    We propose an approach to the study of the evolution of high-apogee twelve-hour orbits of artificial Earth's satellites. We describe parameters of the motion model used for the artificial Earth's satellite such that the principal gravitational perturbations of the Moon and Sun, nonsphericity of the Earth, and perturbations from the light pressure force are approximately taken into account. To solve the system of averaged equations describing the evolution of the orbit parameters of an artificial satellite, we use both numeric and analytic methods. To select initial parameters of the twelve-hour orbit, we assume that the path of the satellite along the surface of the Earth is stable. Results obtained by the analytic method and by the numerical integration of the evolving system are compared. For intervals of several years, we obtain estimates of oscillation periods and amplitudes for orbital elements. To verify the results and estimate the precision of the method, we use the numerical integration of rigorous (not averaged) equations of motion of the artificial satellite: they take into account forces acting on the satellite substantially more completely and precisely. The described method can be applied not only to the investigation of orbit evolutions of artificial satellites of the Earth; it can be applied to the investigation of the orbit evolution for other planets of the Solar system provided that the corresponding research problem will arise in the future and the considered special class of resonance orbits of satellites will be used for that purpose.

    Full Text Available Introduction: Rapid-response teams (RRTs are interdisciplinary groups created to rapidly assess and treat patients with unexpected clinical deterioration marked by decline in vital signs. Traditionally emergency department (ED disposition is partially based on the patients’ vital signs (VS at the time of hospital admission. We aimed to identify which patients will have RRT activation within 12 hours of admission based on their ED VS, and if their outcomes differed. Methods: We conducted a case-control study of patients presenting from January 2009 to December 2012 to a tertiary ED who subsequently had RRT activations within 12 hours of admission (early RRT activations. The medical records of patients 18 years and older admitted to a non-intensive care unit (ICU setting were reviewed to obtain VS at the time of ED arrival and departure, age, gender and diagnoses. Controls were matched 1:1 on age, gender, and diagnosis. We evaluated VS using cut points (lowest 10%, middle 80% and highest 10% based on the distribution of VS for all patients. Our study adheres to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology guidelines for reporting observational studies. Results: A total of 948 patients were included (474 cases and 474 controls. Patients who had RRT activations were more likely to be tachycardic (odds ratio [OR] 2.02, 95% CI [1.25-3.27], tachypneic (OR 2.92, 95% CI [1.73-4.92], and had lower oxygen saturations (OR 2.25, 95% CI [1.42-3.56] upon arrival to the ED. Patients who had RRT activations were more likely to be tachycardic at the time of disposition from the ED (OR 2.76, 95% CI [1.65-4.60], more likely to have extremes of systolic blood pressure (BP (OR 1.72, 95% CI [1.08-2.72] for low BP and OR 1.82, 95% CI [1.19-2.80] for high BP, higher respiratory rate (OR 4.15, 95% CI [2.44-7.07] and lower oxygen saturation (OR 2.29, 95% CI [1.43-3.67]. Early RRT activation was associated with increased healthcare

    BACKGROUND Hypothermic machine perfusion of donor hearts has the theoretical advantage of continuous aerobic metabolism and washes out toxic metabolic byproducts. Here, we studied the effect of hypothermic machine perfusion on cardiac myocyte integrity when hearts are preserved for longer ischemic times (12 hours). MATERIAL AND METHODS Pig hearts were harvested and stored in Celsior® solution for 12 hours using either conventional cold storage on ice (12 h CS, n=3) or pulsatile perfusion with the Paragonix Sherpa Perfusion™ Cardiac Transport System at different flow rates (12 h PP, n=3 or 12 h PP low flow, n=2). After cold preservation, hearts were reperfused using an LV isovolumic Langendorff system. Controls (n=3) were reperfused immediately after organ harvest. Biopsies were taken from the apex of the left ventricle before storage, after storage and after reperfusion to measure ATP and endothelin-1 content in the tissue. TUNEL staining for signs of apoptosis and electron microscopy of the donor hearts were performed. RESULTS 12 h PP hearts showed significantly more weight gain than 12 h CS and controls after preservation. Pulsatile perfused hearts showed less ATP depletion, lower endothelin-1 levels and less apoptosis after preservation compared to CS. Electron microscopy showed damaged muscle fibers, endothelial cell rupture, and injury of mitochondria in the 12 h CS group, while machine perfusion could preserve the cell structures. CONCLUSIONS Hypothermic machine perfusion of donor hearts can preserve the cell structures better than conventional cold storage in prolonged ischemic times. Hypothermic pulsatile perfusion may therefore enable longer preservation times of donor hearts. Whether this method is able to avoid primary graft failure after orthotopic heart transplantation remains to be evaluated in further studies.

    Patients with drug-induced type 1 Brugada electrocardiograms (BrECGs) are considered to have good prognosis. Spontaneous type 1 is, instead, considered a risk factor; however, it is probably underestimated because of the BrECG fluctuations. The aim of this study was to analyze, in a large population of patients with Br, the real prevalence of type 1 BrECG using 12-lead 24-hour Holter monitoring (12L-Holter) and its correlation with the time of the day. We recorded 303 12L-Holter in 251 patients. Seventy-five (30%) patients exhibited spontaneous type 1 BrECG at 12-lead ECG (group 1) and 176 (70%) had only drug-induced type 1 (group 2). Type 1 BrECG was defined as "persistent" (>85% of the recording), "intermittent" (Holter, 57% intermittent type 1%, and 31% never had type 1; in group 2, none had persistent type 1, 20% had intermittent type 1%, and 80% never showed type 1. To evaluate the circadian fluctuations of BrECG, 4 periods in the day were considered. Type 1 BrECG was more frequent between 12-noon and 6 p.m. (52%, p Holter than with conventional follow-up with periodic ECGs and this has important implications in the risk stratification. 12L-Holter recording might avoid 20% of the pharmacological challenges with sodium channel blockers, which are not without risks, and should thus be considered as the first screening test, particularly in children or in presence of borderline diagnostic basal ECG.

    The objective of this double-blind clinical study, conducted in harmony with American Dental Association guidelines, was to compare a new dentifrice formulation variant of Colgate Total Toothpaste containing a special grade of silica (Colgate Total Plus Whitening Toothpaste) to the commercially available, ADA-Accepted and clinically proven Colgate Total Toothpaste for controlling breath odor twelve hours after brushing the teeth. Breath odor was evaluated by a panel of three examiners using a nine-point hedonic scale. Following a baseline evaluation of breath odor, prospective study subjects who scored above the threshold value for unpleasant breath odor were stratified by score and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints or mounthrinses for the next twelve hours, after which they were again evaluated for breath odor. Eighty-three (83) adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. At twelve hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. Importantly, there was no statistical difference between the two dentifrices of the mean twelve-hour breath odor scores. The mean twelve-hour breath scores for the Colgate Total Plus Whitening Toothpaste group and the Colgate Total Toothpaste group were 4.89 and 4.67, respectively, which are within the range of values corresponding to pleasant breath odor. Thus, the results of this double-blind clinical study, conducted according to a protocol which had been approved by the Council on Scientific Affairs of the American Dental Association, support the conclusion that Colgate Total Plus Whitening Toothpaste and Colgate

    Full Text Available Background: Police officers have been reported to exhibit a high incidence of pathologies, which present prematurely in an otherwise healthy population. Shift work has also been associated with an increased risk of cardiovascular and sleep disorders, attributable to its propensity for circadian rhythm dysfunction. However, contention exists as to whether shift work has a direct effect upon blood pressure (BP regulation. Methods: This cross-sectional study sought to determine changes in BP and associations with the overall sleep quality and fatigue in 206 general duties police officers (n = 140 males of the New South Wales Police Force in Australia. The subjects’ BP was assessed before and after their twelve hour shift, during which time they also completed the Lifestyle Appraisal Questionnaire, Pittsburgh Sleep Quality Index (PSQI, Epworth Sleepiness Scale and Fatigue Severity Scale (FSS. Results: Poor sleep quality (PSQI and fatigue severity (FSS were found to predominate in the sample (69% and 51% respectively. Although there was no change in BP for male participants, female officers’ systolic blood pressure (SBP was found to increase significantly across the shift (p < 0.001, but with no change found in females’ diastolic blood pressure (DBP. Finally, higher pre and post-shift SBP (r = −0.26, p = 0.001; r = −0.25, p = 0.001, respectively and DBP (r = −0.26, p = 0.001; r = −0.26, p = 0.001, respectively were significantly correlated with lower FSS scores after accounting for age, waist-hip ratio and lifestyle risk factors. Conclusions: Based on these preliminary findings, there was a significant increase in SBP of female police officers after shift work, while BP and fatigue levels in all police officers were strongly related. Moreover, the predominating poor sleep quality and impact of fatigue in this sample remain a concern. Further research is required to ensure the physiological welfare of police officers, while strategies

    In multiple myeloma, secondary infiltration of adjacent muscles from bone lesions is common. However, plasmacytoma directly arising within the skeletal musculature is rare. Imaging findings of this rare entity have been described only sporadically. The purpose of this study was to identify the clinical signs and radiological features of intramuscular plasmacytoma (IP). Eleven patients with IP were retrospectively identified in the pathological and radiological databases of our institution. Computed tomography (CT) was performed in nine patients and magnetic resonance imaging (MRI) in four cases. IP presented clinically with local pain in four patients. In one case with involvement of the rectus lateralis muscle of the eye, the patient showed a painless bulbus proptosis. In another patient, IP manifested as a massive bilateral forearm swelling with compartment syndrome. In four patients, IP was identified incidentally on computed tomography during staging examination. On imaging, two patterns of IP were found: intramuscular mass (n = 5) or diffuse muscle infiltration (n = 6). On CT with contrast, IP showed a moderate enhancement. With MRI on T1-weighted images, IP was isointense in comparison to the unaffected musculature, whereas on T2-weighted images, IP showed high signal intensity. After intravenous administration of contrast medium, a slight-to-moderate inhomogeneous enhancement was seen in all cases. IP should be considered in the differential diagnosis of muscle tumors. It manifests with two radiological patterns, either as intramuscular mass or as diffuse muscle infiltration. (orig.)

    Compartment syndrome is difficult to diagnose, particularly in patients who are not able to undergo adequate clinical examination. Current methods rely on pressure measurements within the compartment, have high false-positive rates, and do not reliably indicate presence of muscle ischemia. We hypothesized that measurement of intramuscular glucose and oxygen can identify compartment syndrome with high sensitivity and specificity. Compartment syndrome was created in 12 anesthetized adult mixed-sex beagles, in the craniolateral compartment of a lower leg, by infusion of lactated Ringer's solution with normal serum concentration of glucose. The contralateral leg served as a control. Hydrostatic pressure, oxygen tension, and glucose concentration were recorded with commercially available probes. Compartment syndrome was maintained for 8 hours, and the animals were recovered. Two weeks later, compartment and control legs underwent muscle biopsy. Specimens were reviewed by a blinded pathologist. Within 15 minutes of creating compartment syndrome, glucose concentration and oxygen tension in the experimental limb were significantly lower than in the control limb (glucose, p = 0.02; oxygen, p = 0.007; two-tailed t test). Intramuscular glucose concentration of less than 97 mg/dL was 100% sensitive (95% confidence interval [CI], 73-100%) and 75% specific (95% CI, 40-94%) for the presence of compartment syndrome. Partial pressure of oxygen less than 30 mm Hg was 100% sensitive (95% CI, 72-100%) and 100% specific (95% CI, 69-100%) for the presence of compartment syndrome. Pathology confirmed compartment syndrome in all experimental limbs. Our results show that intramuscular glucose concentration and partial pressure of oxygen rapidly identify muscle ischemia with high sensitivity and specificity after experimentally created compartment syndrome in this animal model.

    Infantile hemangiomas demonstrate a pattern of proliferative growth in infancy followed by a slow phase of involution. In contrast a rare type of vascular tumor, intramuscular capillary-type hemangioma, usually presents beyond the period of infancy with nonspecific symptoms and no evidence of involution. The purpose of this study was to characterize the clinical, imaging, histopathological characteristics and management of intramuscular capillary-type hemangioma. We performed a retrospective review of a 20-year period to identify children diagnosed with intramuscular capillary-type hemangioma. Patient demographics, imaging and histopathological findings were recorded. We included 18 children (10 boys, 8 girls) with histologically proven intramuscular capillary-type hemangioma - and adequate imaging. The mean age at presentation was 8.1 years (range 1 day to 19 years). Twelve lesions involved muscles of the extremities, 4 were located in the trunk and 2 were in the head and neck. MRI had been performed in all children and demonstrated a soft-tissue mass with flow voids, consistent with fast flow. The lesion was well-circumscribed in 16 children and intralesional fat was seen in 14. Doppler US demonstrated a heterogeneous lesion, predominantly isoechoic to surrounding muscle, with enlarged arterial feeders. Enlarged feeding arteries, inhomogeneous blush and lack of arteriovenous shunting were noted on angiography (n = 5). The most common histopathological findings were lobules of capillaries with plump endothelium and at least some adipose tissue. The lesions were excised in six children. Two children were lost to follow-up. In the remaining 10, follow-up MRI studies ranging from 3 months to 10 years showed that the lesion enlarged in proportion to the child (n = 7), demonstrated slow growth (n = 2) or remained stable (n = 1). There was no change in imaging characteristics on follow-up. Intramuscular capillary-type hemangioma is a rare benign vascular tumor of

    Full Text Available Berker Bakbak, Banu Turgut Ozturk, Sansal Gedik, Bengu Ekinci Koktekir, Saban Gonul Selcuk University Medical Faculty, Department of Ophthalmology, Konya, Turkey Abstract: A 56-year-old man noted a sudden decrease of vision in his right eye 4 hours after intramuscular triamcinolone acetonide (TA injection. A diagnosis of unilateral nonarteritic anterior ischemic optic neuropathy (NAION was made, and the patient was counseled to discontinue using TA. Examination for possible risk factors revealed controlled hypertension. Final visual acuity was finger counting at 1 m, and the optic disc was pale in his right eye. This is the first reported case of unilateral NAION that has occurred in a patient after intramuscular corticosteroid injection. Although a cause-and-effect relationship is difficult to prove, the short duration between the TA injection and the NAION is noteworthy. The history of corticosteroid injection should be questioned in cases with predisposing conditions such as hypertension. Keywords: ischemic optic neuropathy, corticosteroids, optic disc edema

    We treated a selected group of children attending a difficult asthma clinic with intramuscular triamcinolone acetonide. This study retrospectively reviews markers of asthma severity in those who received one or more monthly doses for three periods: 1) 3 months preceding the first injection (pretreatment), 2) from the first injection to 1 month after the last injection (treatment period), and 3) 3 months after the treatment period (follow-up period). Severity markers during the treatment and follow-up periods were compared with the pretreatment period by paired t-test. Five children (5-13 years old) received a single dose, and 8 children (12-15 years old) received multiple doses. Multiple doses of triamcinolone (n = 3-5) were associated with a fall in the number of asthma exacerbations (P < 0.01) and hospital admissions (P < 0.01) in both the treatment and follow-up periods. A single dose reduced exacerbations (P < 0.05, treatment vs. pretreatment) but not hospital admissions. We conclude that intramuscular triamcinolone is a useful short-term therapy in difficult asthma. Whether its efficacy is due to improved compliance, or an improved anti-inflammatory profile compared with oral steroids, remains unclear. Copyright 2005 Wiley-Liss, Inc

    2003-01-01

    The effect of oral and intramuscular clonidine premedication on the duration of sensory and motor blockade and postoperative analgesia during bupivacaine spinal anaesthesia was studied in 102 ASA physical status I-II patients scheduled for lower limbs orthopaedic surgery. In all cases one hour before anaesthesia midazolam (0.1-0.15 mg/kg) was applied orally and isotonic saline solution (10 ml/kg) was infused intravenously. The patients were randomly allocated into one of the following groups: oral (A) or intramuscular (B) clonidine premedication (0.15 mg) (n = 33) and oral or intramuscular premedication by placebo (C) (n = 36). All patients received 10-20 mg of 0.5% hyperbaric bupivacaine intrathecally. Sensory blockade (SB) was evaluated by pinprick and motor blockade (MB) according to Bromage's scale. The following parameters were measured: duration of motor and sensory block, requirement for postoperative analgesia (buprenorfine); systolic, diastolic and mean blood pressures; heart rate; oxyhemoglobin saturation (SpO2) and adverse events. As far as sex, body weight, age, height, ASA grade, dose of midazolam and bupivacaine, the onset of sensory and motor blockade, level of sensory analgesia, type of surgery and its average duration between groups were concerned, no differences were observed (p > 0.05). Both oral and intramuscular premedication with clonidine increased significantly the duration of motor (A--185.9 +/- 59.3; B--190.9 +/- 66.3 min) and sensory (A--216.2 +/- 69.4; B--254.2 +/- 76.8 min) blockade in comparison with placebo (MB--141.9 +/- 56.6; SB--156.7 +/- 62.9 min) (p premedication with clonidine intensified the sedative effect of midazolam (p clonidine (A--0.6 +/- 0.2; B--0.5 +/- 0.2 mg) nearly twice as small as than in a control group (1.1 +/- 0.2 mg) (p premedication with 0.15 mg of oral and intramuscular clonidine.

    The pharmacokinetic behaviour of oxytetracycline (OTC) was studied in 11 sheep after intravenous and intramuscular administration at a single dosage of 20 mg kg(-1) bodyweight. A conventional formulation was injected by the intravenous route and two different preparations were administered by the intramuscular route: a conventional formulation (T-100) and an aqueous solution of OTC with lidocaine (1 per cent) (OTC-L). The objective was to determine whether there are differences between both formulations in the disposition kinetics of OTC after intramuscular administration to sheep. After intravenous administration of the conventional formulation, plasma oxytetracycline concentrations were best fitted to an open two-compartment model. Mean apparent volume of distribution was 0.77+/-0.02 litre kg(-1) and the harmonic mean half-life was three hours. The OTC transfer process between central and peripheral compartments was fast and that did not influence the elimination process. After intramuscular administrations of both formulations, half-lives were longer than after intravenous administration (mean values of 14.1 and 58.2 hours for T-100 and OTC-L respectively). In both cases, a biphasic absorption, a 'flip-flop' model and a complete bioavailability were found. OTC-L provided therapeutic plasma concentrations over 0.5 microg ml(-1) (the minimum inhibitory concentration for most susceptible pathogens) for a longer period of time than T-100 (72 hours compared with 36 or 48 hours).

    2011-07-01

    Full Text Available Abstract Background Intramuscular pethidine is routinely used throughout the UK for labour analgesia. Studies have suggested that pethidine provides little pain relief in labour and has a number of side effects affecting mother and neonate. It can cause nausea, vomiting and dysphoria in mothers and can cause reduced fetal heart rate variability and accelerations. Neonatal effects include respiratory depression and impaired feeding. There are few large studies comparing the relative side effects and efficacy of different opioids in labour. A small trial comparing intramuscular pethidine with diamorphine, showed diamorphine to have some benefits over pethidine when used for labour analgesia but the study did not investigate the adverse effects of either opioid. Methods The Intramuscular Diamorphine versus Intramuscular Pethidine (IDvIP trial is a randomised double-blind two centre controlled trial comparing intramuscular diamorphine and pethidine regarding their analgesic efficacy in labour and their side effects in mother, fetus and neonate. Information about the trial will be provided to women in the antenatal period or in early labour. Consent and recruitment to the trial will be obtained when the mother requests opioid analgesia. The sample size requirement is 406 women with data on primary outcomes. The maternal primary outcomes are pain relief during the first 3 hours after trial analgesia and specifically pain relief after 60 minutes. The neonatal primary outcomes are need for resuscitation and Apgar Score Discussion If the trial demonstrates that diamorphine provides better analgesia with fewer side effects in mother and neonate this could lead to a change in national practice and result in diamorphine becoming the preferred intramuscular opioid for analgesia in labour.

Total 202 patients received single intramuscular injection of dexketoprofen 50 mg or diclofenac 50 mg postoperatively. The pain intensity (PI was self-evaluated by patients on VAS at baseline 1, 2, 4, 6, and 8 hours. The efficacy parameters were number of responders, difference in PI (PID at 8 hours, sum of analogue of pain intensity differences (SAPID, and onset and duration of analgesia. Tolerability assessment was done by global evaluation and adverse events in each group. Results. Dexketoprofen showed superior efficacy in terms of number of responders (P=.007, PID at 8 hours (P=.02, and SAPID 0–8 hours (P<.0001. It also showed faster onset of action (42 minutes and longer duration of action (6.5 hours. The adverse events were comparable in both groups. Conclusion. Single dose of dexketoprofen trometamol 50 mg given intramuscularly provided faster, better, and longer duration of analgesia in postoperative patients of hernia repair surgery than diclofenac 50 mg, with comparable safety.

    Full Text Available Nicolau syndrome is a rare complication of intramuscular injection consisting of ischemic necrosis of skin, soft tissue, and muscular tissue that arises locoregionally. The characteristic pattern is pain around the injection site, developing into erythema, a livedoid dermatitis patch, and necrosis of the skin, subcutaneous fat, and muscle tissue. Three patients were injected with drugs (diclofenac sodium, ketoprofen, meperidine for pain relief. Three patients complained of pain, and a skin lesion was observed, after which necrosis developed on their buttocks. Each patient underwent debridement and coverage. The wound healed uneventfully. We report three cases of Nicolau syndrome in the buttocks following diclofenac intramuscular injection.

    Human cysticercosis is caused by Cysticercus cellulosae, larvae of a tapeworm, Taenia solium. Cysticercosis can involve any tissue in the body; the most common affected sites are central nervous system, subcutaneous tissue, eyes, and muscles. A few cases of isolated intramuscular cysticercosis without any other tissue involvement have been reported in pediatric population. Here, we report a case of intramuscular cysticercosis diagnosed by ultrasonography in a 5.5 year-old boy who presented with the swellings over the calf and the scapular region, without any associated neurological or ocular involvement. The patient responded well to the course of steroids and Albendazole with complete resolution of both the swellings. PMID:26023298

    The pharmacokinetics of amoxicillin/clavulanic acid (4:1) combination were studied after intravenous and intramuscular administration of single doses (25 mg kg(-1) bodyweight) to 50 pigeons. The plasma concentrations-time data were analysed by compartmental pharmacokinetics and non-compartmental methods. The disposition curves for both drugs after intravenous administration were best described by a two-compartment open model. The apparent volumes of distribution of amoxicillin and clavulanic acid were 1.77 litres kg(-1) and 1.30 litres kg(-1) respectively. The body clearances of amoxicillin and clavulanic acid were not significantly different. The elimination half-lives of amoxicillin after intravenous and intramuscular administration were 1.22 (0.09) hour and 1.52 (0.09) hour respectively, and those of clavulanic acid were 1.15 (0.08) hour and 1.49 (0.08) hour. After intramuscular administration both drugs had a significantly longer half-life (P or =0.5 mg litre(-1) (minimum inhibitory concentration of most susceptible pathogens).

    Full Text Available Introduction: Intramuscular myxoma is a rare benign soft tissue tumor involving the musculoskeletal system. The incidence is reported as varying from 0.1 to 0.13 per 100,000 population. Most patients present between the fifth and sixth decade of life. The swelling commonly occurs in the large muscles of the thigh, shoulder, buttocks and arms. The tumor can be diagnosed with certainty only with histopathological examination. Local recurrence is rare after excision. Case Report: A 73 year old male patient presented to us with a swelling of the anterior aspect of the middle third of the right thigh measuring about 8 x 4 centimeters. He was thoroughly investigated and the swelling excised in toto. The soft cystic swelling excised was found on histopathology to be an intramuscular myxoma. Conclusion: This case report is being presented since the tumor is rare and also an important consideration in the differential diagnosis of sarcomas, intramuscular lipoma, hemangioma, hematoma, and desmoid tumor. Another important feature is that it can be diagnosed with certainty only after excision. Keywords: Intramuscular myxoma, soft tissue swelling, benign.

    The purpose of this study was to examine the intramuscular temperature response during an ice massage treatment. In addition, the effect of subcutaneous tissue thickness and limb circumference on temperature changes was investigated. Intramuscular temperature was measured by intramuscular thermocouples each minute during ice massage treatments of five, ten and fifteen minutes. It was shown that ice massage produces a significant drop in intramuscular temperature. However, there was no significant difference in temperature change after five minutes of treatment. In addition it was shown that there is a high multiple correlation between logarithmic time, subcutaneous tissue thickness, limb circumference, and intramuscular temperature change.

    We report a case of granulocytic sarcoma exclusively manifesting as diffuse intramuscular infiltration of the proximal upper and lower limb girdle and the torso muscles in a patient with previous history of acute myelogenous leukemia 5a. Whole-body CT showed widespread distribution of ill-defined intramuscular, homogeneously enhancing lesions. On whole-body MRI, lesions were homogeneously hyperintense on fat saturated T2-weighted images, isointense on T1-weighted images and strongly enhancing after intravenous gadolinium contrast administration. Histopathology revealed muscular infiltration of blast cells with identical immunochemistry to the initial manifestation of leukemia, diagnostic for an extramedullary relapse manifesting as granulocytic sarcoma. CT and MRI characteristics of this previously undocumented manifestation of granulocytic sarcoma should assist in the identification of such cases. (orig.)

    Full Text Available Nicolau syndrome (NS is a rare complication of an intramuscular injection characterized by severe pain, skin discoloration, and varying levels of tissue necrosis. The case outcomes vary from atrophic ulcers and severe pain to sepsis and limb amputation. We describe a case of a seven-year-old boy with diagnosis of NS after intramuscular benzathine penicillin injection to the ventrolateral aspect of the left thigh. Characteristic violaceous discoloration of skin and immediate injection site pain identified it as a case of NS. The case was complicated by rapid progression of compartment syndrome of the lower limb, proceeding to acute renal failure and death. Associated compartment syndrome can be postulated as a poor prognostic factor for NS.

    Full Text Available Lipomas are common soft tissue tumors of mesenchymal origin.They contain mature adipose tissue. They are usually located in the subcutaneous tissue. They rarely ocur within the muscle and then are called intramuscular lipomas. Ultrasonography is the first diagnostic method to be selected. However, cross-sectional imaging methods are more useful in the diagnosis. On Magnetic resonance imaging (MRI, with the help of signal characteristics and fat suppression techniques,diagnosis is easily achieved. In addition, the relationship of lesion with the adjacent anatomical structures can be assessed better with MRI. Here, will be explained two different intramuscular lipoma cases and imaging findings will be reviewed. [J Contemp Med 2016; 6(3.000: 221-225

    Full Text Available Bioavailability and pharmacokinetics of two commercially available preparations of norfloxacin i.e. A (imported and B (locally prepared were determined in six healthy female goats after single intramuscular administration @ 5 mg/kg b.wt following crossover study design. The blood samples collected at 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8 and 12 hours postmedication were also analysed for drug concentration by microbiological assay. Results revealed that preparation A showed higher (p<0.05 plasma drug levels than the preparation B at 1, 3, 6 and 8 hours after medication. Among bioavailability parameters AUC (g.h/ml and relative bioavailability (F% were higher for preparation A than the preparation B, while other parameters did not differ between the two preparations. Similarly, various pharmacokinetic parameters did not show any statistical difference between preparation A and B. The study revealed comparable elimination kinetics but different bioavailability of two commercial preparations of norfloxacin. It is concluded from the study that for optimal dosage regimen of drugs, the bioequivalence studies and kinetic behavior of the drugs are of paramount importance.

    We report on a rare manifestation of Erdheim-Chester disease with intramuscular lipogranuloma. The patient was a 66-year-old man who noted a soft tissue mass in the right quadriceps femoris muscle. Radiographs revealed symmetrical osteosclerosis in the diametaphysis of both femora and tibiae. An open biopsy revealed a proliferation of lipid-laden histiocytes in the femoral bone marrow and the quadriceps femoris muscle. To our knowledge, this is the second case of Erdheim-Chester disease involving muscle. (orig.)

    Myxomas rare benign mesenchymal neoplasms composed of undifferentiated stellate cells in the myxoid stroma and can affect the heart, subcutaneous tissues, bone and skin. Myxomas arising from muscle tissue are called intramuscular myxomas, and account for 17% of all myxomas. Intramuscular myxomas are most commonly located in the large muscles of the thigh, shoulder, and buttocks. However, intramuscular myxomas of the head and neck region are rarely reported. In this study, we report a case of intramuscular myxoma arising from the paraspinal space of the head and neck region.

    Science.gov (United States)

    Fletcher, C D; Martin-Bates, E

    1988-03-01

    Fifty-four cases of lipoma arising either within or between skeletal muscles are presented. Of these, 52 were identified in a systematic review of 2478 tumours of adipose tissue diagnosed and treated in one hospital over a 25 year period. Intramuscular lipomas account for 1.8% of fatty tumours, arise predominantly in middle to late adult life and, in our series, are commonest on the trunk. They may be divided into infiltrative and well-circumscribed types, respective local recurrence rates being 19 and 0%. Intermuscular lipomas are comparatively rare, 0.3% of fatty tumours, have a similar age distribution and arise most often in the anterior abdominal wall; none of the seven cases recurred. It is important that both pathologists and surgeons appreciate the significant tendency of infiltrative intramuscular lipomas to recur. Hence, preventative surgical measures may be undertaken and worries that the lesion may be sarcomatous can be avoided. Differential diagnosis, most importantly from well-differentiated liposarcoma, is discussed.

    2007-01-01

    Intramuscular hemangioma, an infrequent but important cause of musculoskeletal pain, is often difficult to establish the diagnosis clinically. This report describes a case of a 32-yr-old woman who presented with severe left calf pain for 10 yr. Initial conservative treatments consisting of intramuscular electrical stimulation, herb medication, acupuncture, and intramuscular lidocaine injection under the diagnosis of myofascial pain syndrome in other facilities, failed to alleviate the symptoms. On physical examination, there was no motor weakness or sensory change. Conventional radiography of the leg revealed a soft tissue phlebolith. Conventional angiography study showed hemangioma. Intramuscular hemangioma within the soleus muscle was confirmed by magnetic resonance imaging. Following surgical excision of the hemangioma, the patient's symptom resolved completely. Intramuscular hemangioma is a rare cause of calf pain and should be considered in the differential diagnosis if a patient with muscle pain, particularly if associated with a soft tissue mass, fails to respond to conservative treatment.

    Full Text Available Abstract Background Clinical trials assessing efficacy and safety of Intramuscular (IM Olanzapine in acute schizophrenia and acute mania have previously been undertaken in studies required for drug registration in patients who were required to give informed consent. These patients may have less severe forms of psychosis than patients treated in routine practice. Data derived from naturalistic practice following the launch of IM olanzapine may be helpful for clinicians in assessing efficacy and safety of IM olanzapine. The PANSS-EC scale used in the clinical studies may represent a tool that could be used in routine clinical practice. Case presentation We report on an early unselected case series of 7 patients who received IM olanzapine in routine clinical practice settings in the UK. In this case series, olanzapine IM was generally effective, and no adverse events were reported. Adjunctive benzodiazepines were given concomitantly in 1 of the 7 subjects. This is relevant as concomitant benzodiazepines are not recommended for a minimum of 1 hour post IM olanzapine administration. PANSS-EC data was collected in 2 of the 7 subjects. Conclusion Although patients had greater severity of psychosis than clinical trial patients there were no unexpected findings. In addition the PANSS-EC scale is a scale that may be useful in assessing the efficacy of IM antipsychotics in routine clinical practice.

    This paper outlines twelve tips for undertaking peer observation of teaching in medical education, using the peer review model and the experiences of the authors. An accurate understanding of teaching effectiveness is required by individuals, medical schools, and universities to evaluate the learning environment and to substantiate academic and institutional performance. Peer Observation of Teaching is one tool that provides rich, qualitative evidence for teachers, quite different from closed-ended student evaluations. When Peer Observation of Teaching is incorporated into university practice and culture, and is conducted in a mutually respectful and supportive way, it has the potential to facilitate reflective change and growth for teachers.

    2002-01-01

    Full Text Available Genetic progress depends on germplasm quality and breeding methods. Twelve maize populations and their crosses were evaluated to estimate combining ability and potential to be included as source populations in breeding programs. Plant height, point of insertion of the first ear, number of ears per plant, number of grains per ear, root and stalk lodging and grain yield were studied in two locations in Brazil, during the 1997/98 season. Genotype sum of squares was divided into general (GCA and specific (SCA combining ability. Results indicated the existence of genetic divergence for all traits analyzed, where additive effects were predominant. The high heterosis levels observed, mainly in Xanxerê, suggested the environmental influence on the manifestation of this genetic phenomenon. Populations revealed potential to be used in breeding programs; however, those more intensively submitted to selection could provide larger genetic progress, showing the importance of population improvement for the increment of the heterosis in maize.

  3. Intramuscular Pressure Measurement During Locomotion in Humans

    1996-01-01

    To assess the usefulness of intramuscular pressure (IMP) measurement for studying muscle function during gait, IMP was recorded in the soleus and tibialis anterior muscles of ten volunteers during, treadmill walking, and running using transducer-tipped catheters. Soleus IMP exhibited single peaks during late-stance phase of walking (181 +/- 69 mmHg, mean +/- S.E.) and running (269 +/- 95 mmHg). Tibialis anterior IMP showed a biphasic response, with the largest peak (90 +/- 15 mmHg during walking and 151 +/- 25 mmHg during running) occurring shortly after heel strike. IMP magnitude increased with gait speed in both muscles. Linear regression of soleus IMP against ankle joint torque obtained by a dynamometer in two subjects produced linear relationships (r = 0.97). Application of these relationships to IMP data yielded estimated peak soleus moment contributions of 0.95-165 Nm/Kg during walking, and 1.43-2.70 Nm/Kg during running. IMP results from local muscle tissue deformations caused by muscle force development and thus, provides a direct, practical index of muscle function during locomotion in humans.

    To assess the usefulness of intramuscular pressure (IMP) measurement for studying muscle function during gait, IMP was recorded in the soleus and tibialis anterior muscles of 10 volunteers during treadmill walking and running by using transducer-tipped catheters. Soleus IMP exhibited single peaks during late-stance phase of walking [181 +/- 69 (SE) mmHg] and running (269 +/- 95 mmHg). Tibialis anterior IMP showed a biphasic response, with the largest peak (90 +/- 15 mmHg during walking and 151 +/- 25 mmHg during running) occurring shortly after heel strike. IMP magnitude increased with gait speed in both muscles. Linear regression of soleus IMP against ankle joint torque obtained by a dynamometer produced linear relationships (n = 2, r = 0.97 for both). Application of these relationships to IMP data yielded estimated peak soleus moment contributions of 0.95-1.65 N . m/kg during walking, and 1.43-2.70 N . m/kg during running. Phasic elevations of IMP during exercise are probably generated by local muscle tissue deformations due to muscle force development. Thus profiles of IMP provide a direct, reproducible index of muscle function during locomotion in humans.

    Abstract Introduction: Intramuscular hemangioma (IMH) is a rare congenital soft tissue tumor. Here, we report a case of IMH patient who had undergone several surgeries and other treatments that were all ineffective before he visited us. Clinical Findings: This IMH patient was a 16-yearold male who was born with a tumor of unknown size in his right hand and forearm. On physical examination, the tumor and skin flap complex was seen with a size of 14 cm_12 cm in his right hand, and the multiple postoperative scars were shown on his right hand and forearm. The patient was not able to raise his right shoulder, and the ranges of motion of his right elbow, wrist, and finger were almost zero degrees. Interventions: Considering that the tumor had been surgically excised for several times and the multiple recurrences had affected adversely his daily life, an amputation of his right hand, forearm, and the part of his right arm was performed. Diagnoses: The pathological examination confirmed the diagnosis of IMH. Outcomes: After the amputation surgery, the patient gained a functional recovery and the tumor did not recur during the 2 years after the surgery. Conclusion: A treatment of choice should be personalized according to an IMH patient's overall situation. For an IMH patient like our case with a history of multiple tumor recurrences, we suggest that an amputation surgery should be performed as early as possible to avoid the repeated, but ineffective surgical excisions and the unnecessary sufferings.

  10. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

    Full Text Available Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009, Tethya maza (p = 0.0039, Petromica citrina (p = 0.0277, and Hymeniacidon heliophila (p = 0.00003. These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.

This paper clarified the relationships between compliance coefficients and engineering elastic constants combined with orthotropic properties of wood, and twelve elastic constants of Betula platyphylla Suk. were measured by electrical strain gauges. Spreading the adhesive quantity cannot be excessive or too little when the strain flakes were glued. If excessive, the glue layer was too thick which would influence the strain flakes' performance, and if too little, glues plastered were not firm, which could not accurately transmit the strain. Wood as an orthotropic material, its modulus of elasticity and poisson's ratios are related by two formulas:μij /Ei =μji /Ej and μij 0.95) between the reciprocal of elastic modulus MOE-1 and the square of the ratio of depth to length (h/l)2, which indicate that shear modulus values measured were reliable by three point bending experiment.

    The abundance and cross-linking of intramuscular connective tissue contributes to the background toughness of meat, and is thus undesirable. Connective tissue is mainly synthesized by intramuscular fibroblasts. Myocytes, adipocytes and fibroblasts are derived from a common pool of progenitor cells during the early embryonic development. It appears that multipotent mesenchymal stem cells first diverge into either myogenic or non-myogenic lineages; non-myogenic mesenchymal progenitors then develop into the stromal-vascular fraction of skeletal muscle wherein adipocytes, fibroblasts and derived mesenchymal progenitors reside. Because non-myogenic mesenchymal progenitors mainly undergo adipogenic or fibrogenic differentiation during muscle development, strengthening progenitor proliferation enhances the potential for both intramuscular adipogenesis and fibrogenesis, leading to the elevation of both marbling and connective tissue content in the resulting meat product. Furthermore, given the bipotent developmental potential of progenitor cells, enhancing their conversion to adipogenesis reduces fibrogenesis, which likely results in the overall improvement of marbling (more intramuscular adipocytes) and tenderness (less connective tissue) of meat. Fibrogenesis is mainly regulated by the transforming growth factor (TGF) β signaling pathway and its regulatory cascade. In addition, extracellular matrix, a part of the intramuscular connective tissue, provides a niche environment for regulating myogenic differentiation of satellite cells and muscle growth. Despite rapid progress, many questions remain in the role of extracellular matrix on muscle development, and factors determining the early differentiation of myogenic, adipogenic and fibrogenic cells, which warrant further studies.

    Spiramycin is a macrolide antibiotic that is active against most of the microorganisms isolated from the milk of mastitic cows. This work investigated the disposition of spiramycin in plasma and milk after intravenous, intramuscular and subcutaneous administration. Twelve healthy cows were given a single injection of spiramycin at a dose of 30,000 IU/kg by each route. Plasma and milk were collected post injection. Spiramycin concentration in the plasma was determined by a high performance liquid chromatography method, and in the milk by a microbiological method. The mean residence time after intravenous administration was significantly longer (P less than 0.01) in the milk (20.7 +/- 2.7 h) than in plasma (4.0 +/- 1.6 h). An average milk-to-plasma ratio of 36.5 +/- 15 was calculated from the area concentration-time curves. Several pharmacokinetic parameters were examined to determine the bioequivalence of the two extravascular routes. The dose fraction adsorbed after intramuscular or subcutaneous administration was almost 100% and was bioequivalent for the extravascular routes, but the rates of absorption, the maximal concentrations and the time to obtain them differed significantly between the two routes. Spiramycin quantities excreted in milk did not differ between the two extravascular routes but the latter were not bioequivalent for maximal concentration in the milk. However, the two routes were bio-equivalent for the duration of time the milk concentration exceeded the minimal inhibitory concentration (MIC) of various pathogens causing infections in the mammary gland.(ABSTRACT TRUNCATED AT 250 WORDS)

    OBJECTIVE Hepatic angiosarcoma (HAS), a lethal disease, is the most common sarcoma arising in the liver. Little information about the epidemiology, etiology, diagnosis and management of HAS has been reported. Increased familiarity with this disease will facilitate correct diagnosis and help to improve management of this condition in the future.The objective of this study was to describe cases of hepatic angiosarcoma and to discuss the etiologic, diagnostic, therapeutic features and prognosis of this tumor. This report not only serves to give more evidence of the relationship between hepatic angiosarcoma and carcinogenic exposure, but also demonstrates the key points in different methods of diagnosis and the optimal treatment of hepatic angiosarcoma.METHODS Twelve cases of hepatic angiosareoma were analyzed retrospectively, representing the different character in clinical presentations and laboratory computed tomographical scans; pathological data and treatment are described. Clinical and biologic follow-up was carried out for two years after surgical treatment.RESULTS There were nine men and three women varying in ages from 57 to 71 years with an average of 64.3 years. Ten patientshad a history of exposure to vinyl chloride or thorotrast. Mild or moderate abdominal pain and bloating, abdominal mass and fever were the common clinical presentations. Tumors were visualized by ultrasonography and CT scans in all patients. Biochemical profiles yielded variable results and proved to be of little value in detection or diagnosis. Surgical resection was feasible for each patient who was treated as follows: two wedge resections, six segementectomies and four bisegmentectomies. Five patients received Neoadjuvant chemotherapy postoperatively. The survival rate of those cases was poor. The maximum survival time was fourteen months. The mean survival time for this chemotherapeutic group was 11 months. The difference between the survival time of those treated with an operation

    2007-04-01

    Glut1 is a marker of infantile hemangioma, and its positivity has resulted in defining this tumor at several sites (eg, skin, breast, salivary glands, liver, and placenta). We herein report on the presence of Glut1 positivity in the endothelial cells of 2 examples of intramuscular hemangioma, a peculiar tumor considered to be most probably congenital. The finding expands the sites where infantile hemangioma may be recognized and suggests that this intramuscular variety should be renamed intramuscular infantile hemangioma. An additional previously unreported finding was the presence of a strong membranous pattern of staining for Glut1 in the intralesional fat cells, a known component of the tumor, which parallels that of another endothelial marker, namely CD34. These findings could prove useful for diagnostic purposes in small biopsies.

    The goal of this study is to improve instructional classes for “Extensive Reading”. We compare two approaches. The traditional method is based on the original procedure; the method we try is a “task-placemented” one. inspired by the method we try is a “task-placemented” one. inspired by the theory of “Tasks of Ascending Difficulty”.This paper provides a comparative evaluation of our experiments on Extensive Reading. Our aim is to resolve the logistical problem of heavy teaching loads and limited class hours, which often prevents English learners from fulfilling their study targets and our intended learning outcomes. In view of the experimental data,we have managed to establish a “feedback” to test the two hypotheses, and demonstrate that the new approach contributes to efficient acquisition of the information in the presented reading materials. Our study concludes with an interpretation of the function and merits of this approach.

    Full Text Available Introduction. Rotator cuff intramuscular calcification is a rare condition usually caused by heterotopic ossification and myositis ossificans. Case Presentation. We describe a patient with voluminous calcified mass entrapped in supraspinatus muscle associated with corresponding tendon tear. Histological examination corresponded to a calcified hematoma or necrosis. Patient was surgically managed with open excision of the calcified hematoma and rotator cuff arthroscopic repair. At 6 months, supraspinatus muscle was healed, and functional outcome was good. Discussion and Conclusion. We hypothesized that supraspinatus intramuscular calcified hematoma was responsible for mechanical stress on the tendon. This association has never been described.

    2011-09-01

    Full Text Available Platelet-rich plasma (PRP to increase levels of platelets and growth factors has been used for the treatment of sports injuries suggesting to improve healing and regeneration. This method offers some potential especially for elite athletes. However, the insulin like growth factor-1 (IGF-1 is prohibited by the World Anti Doping Agency and, in addition, there may be a possible link between increased levels of IGF-1 and cancer risk. Aim of the study was to evaluate a systemic increase of IGF-1 after local intramuscular administration of PRP in young healthy moderately trained male subjects. Blood samples were drawn and PRP preparation was performed by means of centrifugation. Enriched plasma was injected into the gluteus muscle. Venous blood was collected and serum prepared before as well as after 0.5, 3 and 24 hours after PRP administration. IGF-1 analysis was performed applying an ELISA test kit. No significant systemic increase of mean IGF-1 was found after the PRP injection. Only one subject showed an increase after 24 h, but all IGF-1 values were found within reference limits. We conclude that a single intramuscular application of PRP does not significantly increase systemic IGF-1 levels. Therefore, a single application of PRP is safe with respect to systemic IGF-1 response and cancer risk and this should be allowed for treatment of muscle injuries in elite athletes

    Postlaparoscopic surgery pain management can reduce the discharge and recovery time. Thus conventional nonsteroidal anti-inflammatory drugs and opioids have been used for this purpose. The aim of this trial was to compare the analgesic and opioid-sparing efficacy of diclofenac sodium intramuscular (IM) with diclofenac transdermal patch in the management of postlaparoscopy pain. Patients were randomized to receive IM diclofenac 75 mg (n=30) 15 minutes before anesthesia or transdermal diclofenac (n=30) 3 hours before laparoscopic surgery. Transdermal or IM diclofenac were reapplied 12 hours later. All patients were administered tramadol intravenously before surgery. Postoperative pain management was maintained with tramadol using a patient-controlled analgesia device. Postoperative visual analogue pain scores (VAS, 0 to 10 cm) and adverse reactions were recorded over a 24-hour period. If VAS values were >4, 25 mg tramadol was given intravenously as a rescue analgesic. In both groups, VAS scores were higher in the first 4 hours. There were no significant differences in postoperative pain between the 2 groups. The postoperative tramadol consumption, and rescue analgesic needs of the patients between both groups were not statistically significant. Injection pain was observed in the IM diclofenac group, but for both groups no skin reactions were observed at the application sites of the drugs. Diclofenac transdermal patch provided pain relief for postoperative laparoscopic surgery as effectively as IM diclofenac and can be used.

    Intramuscular myxoma is a benign soft tissue tumor about which very limited genetic information exists. We studied 68 intramuscular myxomas by means of chromosome banding analysis finding abnormal karyotypes in 21 of them. The most clearly nonrandom involvement was of chromosome 8 which was found gained in seven tumors (+8 was the sole change in five myxomas) and structurally rearranged in another two. Since mutation of the gene GNAS (20q13) has been implicated in the pathogenesis of both solitary and hereditary multiple myxomas, we assessed the transcription and mutation status of this gene in five tumors from which we had suitable RNA. All five intramuscular myxomas expressed biallelic transcripts. The mutated GNAS allele found in one tumor was also biallelically transcribed. In none of the five myxomas were maternally expressed transcripts detected. Collectively, the data suggest that intramuscular myxomas have acquired genetic abnormalities that often include chromosome 8 changes but may also involve alterations of GNAS. To what extent these aberrations are pathogenetically important, remains uncertain.

    The purpose of this study was to determine intravenous (IV), intramuscular (IM) and oral (PO) FM PK in mature swine. Appropriate pain management for lameness in swine is a critical control point for veterinarians and producers, but science-based guidance on optimal housing, management and treatment of lameness is deficient. Six mature swine (121-168 kg) were administered an IV, IM, or PO dose of flunixin meglumine at a target dose of 2.2 mg/kg in a cross-over design with a 10 day washout period between treatments. Plasma samples collected up to 48 hours post-administration were analyzed by high pressure liquid chromatography and mass spectrometry (HPLC-MS) followed by non-compartmental pharmacokinetic analysis. No adverse effects were observed with flunixin meglumine administration for all routes. Flunixin meglumine was administered at an actual mean dose of 2.21 mg/kg (range: 2.05-2.48 mg/kg) IV, IM and PO. A mean peak plasma concentration (CMAX) for IM and PO administration was 3748 ng/ml (range: 2749-6004 ng/ml) and 946 ng/ml (range: 554-1593 ng/ml), respectively. TMAX was recorded at 1.00 hour (range: 0.50-2.00 hours) and 0.61 hours (range: 0.17-2.00 hours) after PO and IM administration. Half-life (T ½ λz) for IV, IM and PO administration was 6.29 hours (range: 4.84-8.34 hours), 7.49 hours (range: 5.55-12.98 hours) and 7.08 hours (range: 5.29-9.15 hours) respectively. In comparison, bioavailability (F) for PO administration was 22% (range: 11-44%) compared to IM F at 76% (range: 54-92%). The results of the present study suggest that FM oral administration is not the most effective administration route for mature swine when compared to IV and IM. Lower F and Cmax of PO-FM in comparison to IM-FM suggest that PO-FM is less likely to be an effective therapeutic administration route.

    The aim of this study was to examine possible signs of impairment of the microcirculation in the lower extremities of female patients suffering from primary restless legs syndrome (RLS)/Willis-Ekbom disease. This study was performed in eight female patients, mean age 48 years (range 21-65), diagnosed with primary RLS but otherwise healthy. Eight healthy female control subjects, mean age 47 years (range 27-64), were also included in the study. Laser Doppler flowmetry was used to determine intramuscular blood flow by placing an optical single fiber in the tibialis anterior muscle belly. The studies were performed between 08.00 and 10.00 hours and 20.00 and 22.00 hours. Blood flow was expressed in perfusion units. The median intramuscular blood flow in the RLS patients' tibialis anterior muscles, recorded from both legs, was significantly higher in the morning, at 17.9 perfusion units, than in the evening, at 12.1 perfusion units (P = 0.004). Corresponding values for the healthy controls were 13.1 perfusion units and 12.0 perfusion units, a non-significant difference. The relative fold changes of microcirculation in the RLS group compared to healthy age-matched controls were 0.7 ± 0.3 and 1.1 ± 0.6, respectively (P = 0.04). Our results suggest that in female patients with primary RLS, the microcirculation in the tibialis anterior muscle is higher in the morning compared with in the evening. © 2014 The Authors.

    Introduction Post-caesarean section pain can be both stressful and unfavourable. Effective and rapid reduction of pain facilitates early ambulation and care of the new born. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) and opioids are used for pain relief but they are associated with adverse effects both in the mother and the child. Aim To evaluate efficacy and safety of piroxicam and tramadol in post-caesarean section pain. Materials and Methods Primigravidae who underwent elective caesarean section received either piroxicam 20mg or tramadol 100mg intra-muscularly, following recovery from anaesthesia. Severity of pain was assessed using Visual Analogue Scale (VAS) and side-effects to study drugs were noted. Rescue analgesic butorphanol 2mg was administered if VAS score was more than four. Patient’s satisfaction score was assessed at 12 hours post-operatively. Results Mean age in piroxicam and tramadol groups were 23.32±3.43 and 22.03±2.0 years respectively. Significant reduction in pain was observed at 2, 4, 8, 12 and 24 hours in both groups (ppiroxicam group compared to tramadol. Twenty-one and 12 patients in tramadol and piroxicam groups received rescue analgesic respectively. Sedation and nausea was significantly higher in tramadol group (ppiroxicam group. Conclusion Intra-muscular piroxicam was effective in reducing post-caesarean section pain for 24 hours with minimal side-effects compared to tramadol. PMID:28050391

    The mammalian/mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway appears to be the primary regulator of muscle protein synthesis. A variety of stimuli including resistance exercise, amino acids, and hormonal signals activate mTORC1 signaling. The purpose of this study was to investigate the effect of a protein supplement on mTORC1 signaling following a resistance exercise protocol designed to promote elevations in circulating hormone concentrations. We hypothesized that the protein supplement would augment the intramuscular anabolic signaling response. Ten resistance-trained men (age, 24.7 ± 3.4 years; weight, 90.1 ± 11.3 kg; height, 176.0 ± 4.9 cm) received either a placebo or a supplement containing 20 g protein, 6 g carbohydrates, and 1 g fat after high-volume, short-rest lower-body resistance exercise. Blood samples were obtained at baseline, immediately, 30 minutes, 1 hour, 2 hours, and 5 hours after exercise. Fine-needle muscle biopsies were completed at baseline, 1 hour, and 5 hours after exercise. Myoglobin, lactate dehydrogenase, and lactate concentrations were significantly elevated after resistance exercise (P exercise also elicited a significant insulin, growth hormone, and cortisol response (P growth factor-1, insulin, testosterone, growth hormone, or cortisol. Intramuscular anabolic signaling analysis revealed significant elevations in RPS6 phosphorylation after resistance exercise (P = .001); however, no differences were observed between trials for signaling proteins including Akt, mTOR, p70S6k, and RPS6. The endocrine response and phosphorylation status of signaling proteins within the mTORC1 pathway did not appear to be altered by ingestion of supplement after resistance exercise in resistance-trained men.

  18. Primary intramuscular hydatid cyst: A rare case report

    2012-01-01

    Full Text Available Hydatid disease has a worldwide distribution and causes health problems in endemic countries. The prevalence of primary muscular hydatid disease is reported to be only 0.5% because muscle is an unfavorable site for infestation as a result of its high levels of lactic acid. Primary intramuscular hydatid cyst presents a diagnostic problem not only because of the unusual location and low prevalence, but also because complicated cysts may imitate solid or complex lesions. We report an unusual case of primary hydatidosis of the calf muscles, in which a wide excision was performed without causing any damage to the cyst wall. Injudicious approach in the management of these rare presentations may be the root cause of severe anaphylactic shock and systemic dissemination. Intramuscular hydatid cysts grow gradually and may mimic a soft tissue tumor; thus, the diagnosis of soft-tissue hydatid cysts needs a high index of suspicion.

    Intramuscular dexamethasone is an effective, but painful, treatment for croup. The effectiveness of betamethasone, an oral, palatable, and equally potent glucocorticoid has not been studied. The purpose of this study was to compare the effectiveness of a single oral dose of betamethasone with intramuscular dexamethasone in the outpatient treatment of mild to moderate croup. Children aged 6 months to 6 years presenting to a tertiary care pediatric emergency department (ED) with a modified Westley croup score of 0 to 11 were randomized to receive either 0.6 mg/kg IM dexamethasone or 0.4 mg/kg PO betamethasone. Croup score, heart rate, respiratory rate, pulse oximetry, and need for supplemental treatments were recorded at study entry and at 1, 2, and 4 hours after treatment. Follow-up data were collected by daily telephone follow-up on persistence of symptoms and the need for additional treatment or physician visits up to 7 days after the ED visit. Each study group contained 26 patients. Despite randomization, the mean baseline croup score was higher in the dexamethasone group (3.6 +/- 2.6 vs. 2.0 +/- 2.4, P = 0.03). Patients in both groups showed a significant reduction in the croup score after treatment, and there were no significant differences between croup scores at 4 hours (P = 0.18). Similarly, there were no differences between groups in the hospital admission rate, time to resolution of symptoms, need for additional treatments, or number of return ED visits. There is no difference between oral betamethasone and intramuscular dexamethasonein the management of mild to moderate viral croup. It is palatable and does not require a nurse for administration, making it a good alternative for ambulatory management.

    Full Text Available Abstract Background Influenza vaccines are recommended for administration by the intramuscular route. However, many physicians use the subcutaneous route for patients receiving an oral anticoagulant because this route is thought to induce fewer hemorrhagic side effects. Our aim is to assess the safety of intramuscular administration of influenza vaccine in patients on oral anticoagulation therapy. Methods Design: Randomised, controlled, single blinded, multi-centre clinical trial. Setting: 4 primary care practices in Barcelona, Spain. Participants: 229 patients on oral anticoagulation therapy eligible for influenza vaccine during the 2003–2004 season. Interventions: intramuscular administration of influenza vaccine in the experimental group (129 patients compared to subcutaneous administration in the control group (100 patients. Primary outcome: change in the circumference of the arm at the site of injection at 24 hours. Secondary outcomes: appearance of local reactions and pain at 24 hours and at 10 days; change in INR (International Normalized Ratio at 24 hours and at 10 days. Analysis was by intention to treat using the 95% confidence intervals of the proportions or mean differences. Results Baseline variables in the two groups were similar. No major side effects or major haemorrhage during the follow-up period were reported. No significant differences were observed in the primary outcome between the two groups. The appearance of local adverse reactions was more frequent in the subcutaneous administration group (37,4% vs. 17,4%, 95% confidence interval of the difference 8,2% to 31,8%. Conclusion This study shows that the intramuscular administration route of influenza vaccine in patients on anticoagulant therapy does not have more side effects than the subcutaneous administration route.

  5. The twelve dimensional super (2+2)-brane

    CERN Document Server

    Hewson, S F

    1996-01-01

    We discuss supersymmetry in twelve dimensions and present a covariant supersymmetric action for a brane with worldsheet signature (2,2), called a super (2+2)-brane, propagating in the osp(64,12) superspace. This superspace is explicitly constructed, and is trivial in the sense that the spinorial part is a trivial bundle over spacetime, unlike the twisted superspace of usual Poincare supersymmetry. For consistency, it is necessary to take a projection of the superspace. This is the same as the projection required for worldvolume supersymmetry. Upon compactification of this superspace, a torsion is naturally introduced and we produce the membrane and type IIB string actions in 11 and 10 dimensional Minkowski spacetimes. In addition, the compactification of the twelve dimensional supersymmetry algebra produces the correct algebras for these theories, including central charges. These considerations thus give the type IIB string and M-theory a single twelve dimensional origin.

    2016-04-01

    The objective of this study was to evaluate the ability of linear regression models to decode patterns of muscle coactivation from intramuscular electromyogram (EMG) and provide simultaneous myoelectric control of a virtual 3-DOF wrist/hand system. Performance was compared to the simultaneous control of conventional myoelectric prosthesis methods using intramuscular EMG (parallel dual-site control)-an approach that requires users to independently modulate individual muscles in the residual limb, which can be challenging for amputees. Linear regression control was evaluated in eight able-bodied subjects during a virtual Fitts' law task and was compared to performance of eight subjects using parallel dual-site control. An offline analysis also evaluated how different types of training data affected prediction accuracy of linear regression control. The two control systems demonstrated similar overall performance; however, the linear regression method demonstrated improved performance for targets requiring use of all three DOFs, whereas parallel dual-site control demonstrated improved performance for targets that required use of only one DOF. Subjects using linear regression control could more easily activate multiple DOFs simultaneously, but often experienced unintended movements when trying to isolate individual DOFs. Offline analyses also suggested that the method used to train linear regression systems may influence controllability. Linear regression myoelectric control using intramuscular EMG provided an alternative to parallel dual-site control for 3-DOF simultaneous control at the wrist and hand. The two methods demonstrated different strengths in controllability, highlighting the tradeoff between providing simultaneous control and the ability to isolate individual DOFs when desired.

  8. Intermuscular and intramuscular adipose tissues: Bad vs. good adipose tissues.

    Human studies of the influence of aging and other factors on intermuscular fat (INTMF) were reviewed. Intermuscular fat increased with weight loss, weight gain, or with no weight change with age in humans. An increase in INTMF represents a similar threat to type 2 diabetes and insulin resistance as does visceral adipose tissue (VAT). Studies of INTMF in animals covered topics such as quantitative deposition and genetic relationships with other fat depots. The relationship between leanness and higher proportions of INTMF fat in pigs was not observed in human studies and was not corroborated by other pig studies. In humans, changes in muscle mass, strength and quality are associated with INTMF accretion with aging. Gene expression profiling and intrinsic methylation differences in pigs demonstrated that INTMF and VAT are primarily associated with inflammatory and immune processes. It seems that in the pig and humans, INTMF and VAT share a similar pattern of distribution and a similar association of components dictating insulin sensitivity. Studies on intramuscular (IM) adipocyte development in meat animals were reviewed. Gene expression analysis and genetic analysis have identified candidate genes involved in IM adipocyte development. Intramuscular (IM) adipocyte development in human muscle is only seen during aging and some pathological circumstance. Several genetic links between human and meat animal adipogenesis have been identified. In pigs, the Lipin1 and Lipin 2 gene have strong genetic effects on IM accumulation. Lipin1 deficiency results in immature adipocyte development in human lipodystrophy. In humans, overexpression of Perilipin 2 (PLIN2) facilitates intramyocellular lipid accretion whereas in pigs PLIN2 gene expression is associated with IM deposition. Lipins and perilipins may influence intramuscular lipid regardless of species.

    Full Text Available Moxifloxacin is a novel fourth generation fluoroquinolone with broad spectrum of antibacterial activity. The study was conducted to evaluate the safety of Moxifloxacin (5.0 mg/kg after repeated intramuscular administration at 24 h interval for 14 days in male and female wistar rats. Hematological (Haemoglobin, RBC, WBC, MCV, MCH, MCHC, HCT and DLC, blood biochemical parameters (AST, ALT, ALP, Total Bilirubin, Total Serum Protein, Serum Albumin, Globulin, Serum Creatinine, Urea, Uric acid and Blood glucose and histopathological examination of various tissues were carried out in the present study. Male and female animals of any group did not reveal any clinical symptoms and mortality attributable to the 14 days intramuscular administration of Moxifloxacin. The data were compared by unpaired two tail `t` test using Graph Pad Prism (Version 4.00. All above hematological and blood biochemical parameters were found to fluctuate within normal range during treatment period and the mean values were not significantly differ (p < 0.05 from corresponding control values. Moreover, no gross or microscopic changes were found in the liver, kidney, heart, spleen, stomach, intestine and joint cartilages of the treated wistar rats. Results indicate that daily administration of Moxifloxacin for 14 days seems to be safe and well tolerated in rats. [Veterinary World 2010; 3(10.000: 449-452

    2010-01-01

    Cases of catatonia in patients with renal failure have been rarely reported. In this report, we describe two renal-insufficient patients with catatonia who had a good response to intramuscular lorazepam whereby the catatonic symptoms were relieved. Case 1 involved a patient with end-stage renal disease and severe pneumonia related respiratory failure. He responded well to intramuscular lorazepam (total dose, 4 mg) whereby the catatonia was elieved. Case 2 involved a patient with alcoholic liver cirrhosis and rhabdomyolysis-related acute renal failure. He showed great improvement with intramuscular lorazepam (2 mg) whereby the catatonia was subsequently relieved. This report demonstrates that intramuscular lorazepam is safe, effective and rapid in relieving catatonia associated with renal function impairment. Neither of the patients had a recurrence of catatonia during a period of 6- months follow-up. In conclusion, intramuscular lorazepam may play an important role in the treatment of catatonia associated with renal insufficiency.

    The pharmacokinetics and intramuscular (IM) bioavailability of flumequine (15 mgkg(-1)) were investigated in healthy pigs and the findings related to published minimal inhibitory concentrations (MICs) for susceptible bacteria of animal origin, and to experimentally determined MICs for susceptible strains of porcine origin. We found MICs for Escherichia coli, Salmonella spp., Pasteurella spp. and Bordetella spp. in the range 0.5 to >64 microg mL(-1) isolated from infected pigs in the Forli area of Italy; only the Pasteurella multocida strains were sensitive (MIC(90)=0.5 microg mL(-1)). After intravenous (IV) injection, flumequine was slowly distributed and eliminated (t(1/2lambda(1))1.40+/-0.16 h and t(1/2lambda(2))6.35+/-1.69 h). The distribution volume at steady state (V(dss)) was 752.59+/-84.03 mL kg(-1) and clearance (Cl(B)) was 237.19+/-17.88 mL kg(-1)h(-1). After IM administration, peak serum concentration (4.99+/-0.92 microg mL(-1)) was reached between the 2nd and the 3rd hour. The results on MIC of isolated bacteria, although only indicative, suggest that the efficacy of flumequine on Gram-negative bacteria may be impaired by the emergence of less sensitive or resistant strains.

    2012-09-01

    Full Text Available Platelet-rich plasma (PRP has been employed to treat sports injuries to possibly accelerate healing and regeneration. This method offers some potential, especially for athletes. Growth factors are generally prohibited by the World Anti Doping Agency with exception to PRP which may induce adverse effects. The aim of this study was to evaluate any systemic increase of growth factors such as Insulin Like Growth Factor-1, Endothelial Growth Factors, Platelet-Derived Growth Factors, Fibroblast Growth Factors, Vascular-Endothelial Growth Factor and Transforming Growth Factors after local intramuscular administration of PRP in young, healthy male subjects keeping in mind adverse treatment effects. Enriched plasma from centrifuged blood samples was injected into the gluteus muscle. Venous blood was collected and serum prepared before as well as 0.5, 3 and 24 hours after PRP administration. Growth factors were analyzed using ELISA test kits. No significant systemic increase of growth factor levels was found after PRP injection except TGF-ß2. For that reason the PRP method may be applied for muscle injury treatment in elite athletes although further studies are necessary to clarify the response to the unspecific increased TGF-ß2 blood levels, which could increase the risk for local fibrosis

    With the rapidly developed micromachining technology, various kinds of sophisticated microelectrodes integrated with micro fluidic channels are design and fabricated for not only electrophysiological recording and stimulation, but also chemical drug delivery. As many efforts have been devoted to develop rigid microprobes for neural research of brain, few researchers concentrate on fabrication of flexible microelectrodes for intramuscular electrophysiology and chemical interfacing. Since crude wire electrodes still prevail in functional electrical stimulation (FES) and electromyography (EMG) recording of muscle, here we introduce a flexible micro tube electrode combining electrical and chemical pathway. The proposed micro tube electrode is manufactured based on polymer capillary, which provide circumferential electrode site contacting with electro-active tissue and is easy to manufactured with low cost.

    2006-05-01

    Serum sickness is a type III hypersensitivity reaction mediated by immune complex deposition with subsequent complement activation, small-vessel vasculitis, and tissue inflammation. Although the overall incidence of serum sickness is declining because of decreased use of heterologous sera and improved vaccinations, rare sporadic cases of serum sickness from nonprotein drugs such as penicillins continue to occur. Drug-induced serum sickness is usually self-limited, with symptoms lasting only 1-2 weeks before resolving. We report an unusual case of a severe and prolonged serum sickness reaction that occurred after exposure to an intramuscular penicillin depot injection (probable relationship by Naranjo score) and discuss how pharmacokinetics may have played a role. Clinicians should be familiar with serum sickness reactions particularly as they relate to long-acting penicillin preparations. Accurate diagnosis in conjunction with cessation of drug exposure and prompt initiation of antiinflammatory treatment with corticosteroids can produce complete recovery

    1993-09-01

    The lateral cricoarytenoid (LCA) muscle is one of the adductors of the vocal cords; however, some investigators believe that the lateral edge of the muscle may be involved in abduction. The possibility of functionally distinct compartments within the LCA was investigated by observing the pattern of the intramuscular nerve supply. This technique has previously clearly demonstrated neural compartments in the posterior cricoarytenoid, thyroarytenoid and cricothyroid muscles. Five adult human larynges were processed by the Sihler's stain which clears all soft tissue while counterstaining the nerves. The results of our study showed that the innervation pattern of the human LCA muscle is composed of a homogenous nerve plexus localized to the middle region of the muscle. This pattern correlates with the location of motor endplates described by prior investigators. The consistent neural pattern suggests that the LCA is composed of a single neuromuscular compartment.

    Full Text Available Objective. Intramuscular adipose tissue (IMAT and sarcopenia may adversely impact mobility function and physical activity. This study determined the association of locomotor muscle structure and function with mobility function in older adults. Method. 109 older adults with a variety of comorbid disease conditions were examined for thigh muscle composition via MRI, knee extensor strength via isometric dynamometry, and mobility function. The contribution of strength, quadriceps lean tissue, and IMAT to explaining the variability in mobility function was examined using multivariate linear regression models. Results. The predictors as a group contributed 27–45% of the variance in all outcome measures; however, IMAT contributed between 8–15% of the variance in all four mobility variables, while lean explained only 5% variance in only one mobility measure. Conclusions. Thigh IMAT, a newly identified muscle impairment appears to be a potent muscle variable related to the ability of older adults to move about in their community.

  9. Putative regulatory factors associated with intramuscular fat content.

    Directory of Open Access Journals (Sweden)

    Aline S M Cesar

    Full Text Available Intramuscular fat (IMF content is related to insulin resistance, which is an important prediction factor for disorders, such as cardiovascular disease, obesity and type 2 diabetes in human. At the same time, it is an economically important trait, which influences the sensorial and nutritional value of meat. The deposition of IMF is influenced by many factors such as sex, age, nutrition, and genetics. In this study Nellore steers (Bos taurus indicus subspecies were used to better understand the molecular mechanisms involved in IMF content. This was accomplished by identifying differentially expressed genes (DEG, biological pathways and putative regulatory factors. Animals included in this study had extreme genomic estimated breeding value (GEBV for IMF. RNA-seq analysis, gene set enrichment analysis (GSEA and co-expression network methods, such as partial correlation coefficient with information theory (PCIT, regulatory impact factor (RIF and phenotypic impact factor (PIF were utilized to better understand intramuscular adipogenesis. A total of 16,101 genes were analyzed in both groups (high (H and low (L GEBV and 77 DEG (FDR 10% were identified between the two groups. Pathway Studio software identified 13 significantly over-represented pathways, functional classes and small molecule signaling pathways within the DEG list. PCIT analyses identified genes with a difference in the number of gene-gene correlations between H and L group and detected putative regulatory factors involved in IMF content. Candidate genes identified by PCIT include: ANKRD26, HOXC5 and PPAPDC2. RIF and PIF analyses identified several candidate genes: GLI2 and IGF2 (RIF1, MPC1 and UBL5 (RIF2 and a host of small RNAs, including miR-1281 (PIF. These findings contribute to a better understanding of the molecular mechanisms that underlie fat content and energy balance in muscle and provide important information for the production of healthier beef for human consumption.

    The wind process is essential for hydrometeorology and additionally, is one of the basic renewable energy resources. Most stochastic forecast models are limited up to daily scales disregarding the hourly scale which is significant for renewable energy management. Here, we analyze hourly wind timeseries giving emphasis on the temporal distribution of wind within the day. We finally present a periodic model based on statistical as well as hydrometeorological reasoning that shows good agreement with data.

  12. The twelve theses: a call to a new reformation

    Full Text Available With every discovery emerging from the world of science over the last 500 years concerning the origins of the universe and of life itself, the traditional explanations offered by the Christian Church appeared to be more and more dated and irrelevant.  Christian leaders, unable to embrace the knowledge revolution seemed to believe  that the only way to save Christianity was not to disturb the old patterns either by listening to, much less by entertaining the new knowledge. I tried to articulate this challenge in a book entitled: Why Christianity Must Change or Die, published in 1998.  In that book I examined in detail the issues that I was convinced Christianity must address. Shortly after that book was published I reduced its content to twelve theses, which I attached in Luther-like fashion to the great doors on the Chapel of Mansfield College at Oxford University in the United Kingdom. I then mailed copies of those Twelve Theses to every acknowledged Christian leader of the world. It was an attempt to call them into a debate on the real issues that I was certain the Christian Church now faced.  I framed my twelve theses in the boldest, most provocative language possible, designed primarily to elicit response and debate. I welcome responses from Christians everywhere.  I claim no expertise or certainty in developing answers, but I am quite confident that I do understand the problems we are facing as Christians who are seeking to relate to the 21st century.

    Phosphotyrosine interaction domain containing 1 (PID1), a recently identified gene involved in obesity-associated insulin resistance, plays an important role in fat deposition. However, its effect on porcine intramuscular preadipocyte proliferation and differentiation remains poorly understood. In this study, the plasmid pcDNA3.1(+)-pPID1 was transfected into porcine intramuscular preadipocytes with Lipofectamine 3000 reagent to over-express porcine PID1 (pPID1). Over-expression of pPID1 significantly promoted porcine intramuscular preadipocyte proliferation. Expression of pPID1 mRNA was significantly increased upon porcine intramuscular preadipocyte differentiation. Indirect fluorescent immunocytochemistry demonstrated that pPID1 protein was localized predominantly in the nucleus of porcine intramuscular preadipocyte. The mRNA levels of peroxisome proliferators-activated receptor γ, CCAAT/enhancer binding protein α and lipoprotein lipase were significantly increased by pPID1 over-expression. Over-expression of pPID1 also led to an increase in lipid accumulation which was detected by Oil Red O staining, and significantly increased the intramuscular triacylglycerol content. These results indicate that pPID1 may play a role in enhancing porcine intramuscular preadipocyte proliferation and differentiation.

    2014-06-01

    Full Text Available Intensive production conditions, selection directed to increase the percentage of muscle tissue in carcasses and consumer demand have led to a reduction of intramuscular fat content in pig carcasses. Intramuscular fat is a factor affecting the flavor, juiciness and tenderness of pork meat. FABP protein family causes the differences in the content of intramuscular fat in different pig breeds. FABP3 and LEPR gene are candidate genes for intramuscular fat content and their polymorphisms explain the variability that can occur in different pig breeds. The aim of this paper is to demonstrate the influence of genes on different intramuscular fat content in pig carcasses due to pigs genotype.

    Full Text Available 7 positions in 2 hours (2013 is a drawing that documents the process of making the short film Role Reversal Rehearsal. It became quickly apparent that the process of making the work was more dynamic and interesting than the finished piece itself. Relationships between the childcare arrangements of the participants and the collective working process brought about the necessity of collaboration for parent artists. Each participant gave their time, energy and creative insight towards filming a series of birthing positions with roles reversed. The male performer became the central figure in an attempt to prompt empathy, humour, and to embody the importance of the male role in childbirth. There were two hours to choreograph, rehearse, and film the sequence. The drawing by Ackerman encapsulates the 'rhizomatic' approach to producing creative work under the constraints of parenthood. The 'arborescent' structure of hierarchy encouraged in industrial filmmaking is subsumed in favour of a horizontal structure. This new structure allows for the creative input, and flow of collaboration between all people involved - including the 3 and 5 year olds, who contributed ideas for camera and soundtrack in situ.

    2016-10-01

    A 3-monthly formulation of intramuscular paliperidone palmitate (3-monthly paliperidone palmitate) has recently been approved for the maintenance treatment of schizophrenia in adult patients in the EU (Trevicta(®)), following earlier approval in the USA (Invega Trinza(®)). This narrative review discusses the clinical use of 3-monthly paliperidone palmitate in the maintenance treatment of schizophrenia in adult patients and summarizes its pharmacological properties. The efficacy of the 3-monthly paliperidone palmitate formulation as a maintenance treatment for schizophrenia has been demonstrated in well designed, phase III trials. Three-monthly paliperidone palmitate was more effective than placebo in delaying time to relapse and reducing relapse rates, and was noninferior to 1-monthly paliperidone palmitate in the proportion of patients that remained relapse-free. The 3-monthly formulation was also more effective than placebo in controlling the symptoms of schizophrenia, whilst not differing significantly from the 1-monthly formulation in terms of symptomatic control. Three-monthly paliperidone palmitate was generally well tolerated in clinical trials, with a tolerability profile consistent with that of the 1-monthly formulation. In conclusion, 3-monthly paliperidone palmitate is a useful treatment option for adult patients with schizophrenia who are adequately treated with the 1-monthly formulation, particularly for those who would prefer, or may benefit from, longer dosing intervals.

    2015-05-01

    Full Text Available INTRODUCTION: Hydatid disease has a worldwide distribution and causes health problems in endemic countries. The parasite has a "dog - sheep" cycle with man as an intermediate accidental host. When humans ingest the eggs of the tapeworm, the embryos that emer ge penetrate the intestinal mucosa and are transported via the circulation to various organs. Most commonly they reach the liver, lungs and the other organs are rarely affected. Primary hydatid cyst of skeletal muscle is rare, occurring in 1 - 3% of all case s. (1,2 The prevalence of intramuscular hydatid disease is reported to be less than 0.5% , because muscle is an unfavourable site for infestation because of high levels of lactic acid in muscle. (3 The diagnosis is difficult because of the unusual location, low prevalence and complicated cysts may mimic solid or complex lesions. (4 The differential diagnosis in these cases must include malignant soft - tissue tumors such as myxoid liposarcoma, soft tissue abscesses and chronic hematoma. (5 Hydatid disease of h umans caused by Echinococcus granulosus has been recognized as a major public health problem. It is found in all sheep - raising countries of the world. In India, the highest prevalence is reported from Andhra Pradesh and Tamil Nadu. (6 Injudicious approach in the management of these rare presentations may be the root cause of severe anaphylactic shock and systemic dissemination. We report an unusual case of primary hydatidosis of the paraspinal muscles

    The purpose of this study was to determine the pharmacokinetics of buprenorphine following intravenous (i.v.) and intramuscular (i.m.) administration in horses. Six horses received i.v. or i.m. buprenorphine (0.005 mg/kg) in a randomized, crossover design. Plasma samples were collected at predetermined times and horses were monitored for adverse reactions. Buprenorphine concentrations were measured using ultra-performance liquid chromatography with electrospray ionization mass spectrometry. Following i.v. administration, clearance was 7.97±5.16 mL/kg/min, and half-life (T(1/2)) was 3.58 h (harmonic mean). Volume of distribution was 3.01±1.69 L/kg. Following i.m. administration, maximum concentration (C(max)) was 1.74±0.09 ng/mL, which was significantly lower than the highest measured concentration (4.34±1.22 ng/mL) after i.v. administration (PBuprenorphine has a moderate T(1/2) in the horse and was detected at concentrations expected to be therapeutic in other species after i.v. and i.m. administration of 0.005 mg/kg. Signs of excitement and gastrointestinal stasis may be noted.

    In order to extend scientific knowledge on autochthonous Italian equine meat, the physical-chemical parameters of Catria Horse Longissimus thoracis (LT) muscle and its nutritional characteristics have been investigated. Ten steaks of Catria foal raised at pasture and fattened indoors for 2 months were dissected, and LT muscle was analyzed for chemical composition, total iron, drip loss, colorimetric characteristics, intramuscular fat, fatty acid profile and nutritional indexes. Steak dissection showed that LT muscle accounted for 36.78% and fat accounted for 9.19% of weight of steak. Regarding chemical composition, protein and fat content was 20.31% and 2.83%, respectively. Total iron content (1.95 mg/100 g) was lower than data reported in the literature. Color parameters showed a luminous and intense red hue muscle. The sum of unsaturated fatty acid composition (50.3%) was higher than the sum of saturated fatty acids (46.64 %). The fatty acid profile and nutritional values of Catria Horse meat could be modified adopting extensive rearing systems and grazing. The data suggests that further investigation on the composition of Catria Horse meat should be carried out to valorize this autochthonous breed, reared in sustainable livestock systems, and its meat in local short-chain systems. © 2016 Japanese Society of Animal Science.

    Conduction of electrical signals along the surface of muscle fibers is acknowledged as an essential neuromuscular component which is linked with muscle force production. However, it remains unclear whether muscle fiber conduction velocity (MFCV) is also linked with explosive performance. The aim of the present study was to investigate the relationship between vastus lateralis MFCV and countermovement jumping performance, the rate of force development and maximum isometric force. Fifteen moderately-trained young females performed countermovement jumps as well as an isometric leg press test in order to determine the rate of force development and maximum isometric force. Vastus lateralis MFCV was measured with intramuscular microelectrodes at rest on a different occasion. Maximum MFCV was significantly correlated with maximum isometric force (r = 0.66, p rate of force development at 100 ms, 150 ms, 200 ms, and 250 ms (r = 0.85, r = 0.89, r = 0.91, r = 0.92, respectively, p rate of force development than with maximum isometric leg press force. Lower, but significant correlations were found between mean MFCV and countermovement jump power (r = 0.65, p rate of force development than with isometric force, perhaps because conduction velocity is higher in the larger and fastest muscle fibers which are recognized to contribute to explosive actions.

    Full Text Available Introduction: Epinephrine is the treatment of choice for anaphylaxis. We surveyed emergency department (ED healthcare providers regarding two methods of intramuscular (IM epinephrine administration (autoinjector and manual injection for the management of anaphylaxis and allergic reactions and identified provider perceptions and preferred method of medication delivery. Methods: This observational study adhered to survey reporting guidelines. It was performed through a Web-based survey completed by healthcare providers at an academic ED. The primary outcomes were assessment of provider perceptions and identification of the preferred IM epinephrine administration method by ED healthcare providers. Results: Of 217 ED healthcare providers invited to participate, 172 (79% completed the survey. Overall, 82% of respondents preferred the autoinjector method of epinephrine administration. Providers rated the autoinjector method more favorably for time required for training, ease of use, convenience, satisfaction with weight-based dosing, risk of dosing errors, and speed of administration (p<0.001 for all comparisons. However, manual injection use was rated more favorably for risk of provider self-injury and patient cost (p<0.001 for both comparisons. Three participants (2% reported a finger stick injury from an epinephrine autoinjector. Conclusion: ED healthcare providers preferred the autoinjector method of IM epinephrine administration for the management of anaphylaxis or allergic reactions. Epinephrine autoinjector use may reduce barriers to epinephrine administration for the management of anaphylaxis in the ED.

    The pharmacokinetics of marbofloxacin was investigated after intravenous (IV) and intramuscular (IM) administration, both at a dose rate of 5 mg/kg BW, in six clinically healthy domestic ostriches. Plasma concentrations of marbofloxacin was determined by a HPLC/UV method. The high volume of distribution (3.22+/-0.98 L/kg) suggests good tissue penetration. Marbofloxacin presented a high clearance value (2.19+/-0.27 L/kgh), explaining the low AUC values (2.32+/-0.30 microgh/mL and 2.25+/-0.70 microgh/mL, after IV and IM administration, respectively) and a short half life and mean residence time (t(1/2 beta)=1.47+/-0.31 h and 1.96+/-0.35 h; MRT=1.46+/-0.02 h and 2.11+/-0.30 h, IV and IM, respectively). The absorption of marbofloxacin after IM administration was rapid and complete (C(max)=1.13+/-0.29 microg/mL; T(max)=0.36+/-0.071 h; MAT=0.66+/-0.22 h and F (%)=95.03+/-16.89).

    1997-11-01

    The purpose was to investigate the activation pattern of five major hip flexor muscles and its adaptation to changing speed and mode of progression. A total of 11 healthy subjects performed walking and running on a motor-driven treadmill at speeds ranging from 1.0 to 6.0 m s-1. Intramuscular fine-wire electrodes were used to record myoelectric signals from the iliacus, psoas, sartorius, rectus femoris and tensor fascia latae muscles. The basic pattern, with respect to number of activation periods, remained the same irrespective of speed and mode of progression. However, differences in the relative duration and timing of onset of activation occurred between individual muscles. Over the speed range in walking, a progressively earlier onset was generally seen for the activation period related to hip flexion. Changes in EMG amplitude were measured in the iliacus and psoas muscles and showed a marked increase and difference between walking and running at speeds above 2.0 m s-1. Thus, the alternating flexion-extension movements at the hip during locomotion appear to be governed by a rather fixed 'neural program' which normally only needs minor modulations to accomplish the adjustments accompanying an increase in speed of progression as well as a change from walking to running.

The research objective was to evaluate several drug combinations for intramuscular anesthesia in chickens for physiologic, nutritional, pharmacological and other investigations. Meterial & Methods: Sixty healthy chickens were randomly assigned in six treatment groups and received Ketamine in combination with Xylazine, Midazolam or Acepromazine. Heart and respiratory rate, induction time, duration of surgical anesthesia and light anesthesia were measured. Results: Induction of anesthesia was significantly longer following Acepromazine- Ketamine and Midazolam- Ketamine compared to other groups (P<0.05. Duration of surgical anesthesia was longest with Xylazine- Midazolam- Ketamine and shortest with Midazolam-Ketamine and Acepromazine- Ketamine (P<0.05. Conclusion: In conclusion, the most effective drug combinations resulting in longer duration of surgical anesthesia, were Xylazine- Acepromazine- Ketamine and Xylazine- Midazolam- Ketamine. Other combinations did not produce appropriate surgical anesthesia, but they make slight changes in physiological data.

    The partitioning of total dissectible body fat and the amounts of intramuscular fat in Psoas major, Semitendinosus and Biceps brachii muscles were determined in two groups of A. Angus and AA × Nelore steers with similar averages of total dissectible fat (27·7 kg). In addition, the fatty acid composition of total fat and the triglyceride fraction from dissectible and intramuscular fats were determined. The AA × Nelore steers have higher levels of subcutaneous fat and lower levels of intermuscular fat than the A. Angus but contain lower levels of intramuscular fat in the three muscles. The allometric regressions varied according to the muscle and breed type. The fatty acid composition of subcutaneous and kidney fats were similar but differences in the percentages of 14:0, 18:0, 18:2 and 20:4 fatty acids in intramuscular fats between the two genetic groups were detected.

    Dyslexia is a common learning difficulty. As a result of SS' own experiences as a medical student with dyslexia, we have been researching and teaching on this topic for the past two years. Here, we present twelve tips for teaching medical students with dyslexia. These are gathered from our personal experiences and research, discussions with other educators, and wider literature on the topic. This article aims to shed some light on dyslexia, and also to make practical suggestions. Teaching students with dyslexia should not be a daunting experience. Small changes to existing methods, at minor effort, can make a difference - for example, adding pastel colors to slide backgrounds or avoiding Serif fonts. These tips can help educators gain more insight into dyslexia and incorporate small, beneficial adaptations into their teaching.

    2017-09-17

    Medical education is an expanding area of specialist interest for medical professionals. Whilst most doctors will be familiar with the compilation of clinical portfolios for scrutiny of their clinical practice and provision of public accountability, teaching portfolios used specifically to gather and demonstrate medical education activity remain uncommon in many non-academic settings. For aspiring and early career medical educators in particular, their value should not be underestimated. Such a medical educator's portfolio (MEP) is a unique compendium of evidence that is invaluable for appraisal, revalidation, and promotion. It can stimulate and provide direction for professional development, and is a rich source for personal reflection and learning. We recommend that all new and aspiring medical educators prepare an MEP, and suggest twelve tips on how to skillfully compile one.

    We present spectra of twelve Type Ia supernovae obtained in 1999 at the William Herschel Telescope and the Nordic Optical Telescope during a search for Type Ia supernovae (SN Ia) at intermediate redshift. The spectra range from z=0.178 to z=0.493, including five high signal-to-noise ratio SN Ia spectra in the still largely unexplored range 0.15 < z < 0.3. Most of the spectra were obtained before or around restframe B-band maximum light. None of them shows the peculiar spectral features found in low-redshift over- or under-luminous SN Ia. Expansion velocities of characteristic spectral absorption features such as SiII at 6355 angs., SII at 5640 angs. and CaII at 3945 angs. are found consistent with their low-z SN Ia counterparts.

    Neurofibromas are uncommon benign tumours and are still rarer in intramuscular locations. They are not detected until they cause a significant damage to the neighbouring tissues. We present a case of a giant intramuscular myxoid neurofibroma of the left forearm which eroded the radius and ulna, restricting the movements at the elbow and wrist joints and causing wrist drop resulting in an above elbow amputation. It was diagnosed by histopathology and was later confirmed by immunohistochemistry. PMID:23198230

    It has been reported that the quantity of fibrillation potentials (FP) decreases with drop in the intramuscular temperature. However, the quantitative measurement of the FP with intramuscular temperature changes has not been reported. Under anesthesia of intraperitoneal sodium pentobarbital, the sciatic nerve of 6 rats (Sprague-Dawley) was surgically isolated. A 1-cm segment was excised after tying the proximal and distal ends of the nerve segment. A concentric needle electrode and thermomete...

    In settings where most workers have full-time schedules, hourly wages are appropriate primary indicators of job quality and worker outcomes. However, in sectors where full-time schedules do not dominate - primarily service-producing activities - total hours matter, in addition to hourly wages, for job quality and worker outcomes. In this paper we employ a sector-focused, comparative framework to further examine hours levels - measured as average weekly hours - and trends in Canada, the United...

    Intramuscular bleeding of the tongue is frequently observed in autopsy cases of house fire victims. The meaning of this finding has not yet been fully discussed. We examined 69 autopsy cases of house fire victims and investigated several factors contributing to intramuscular bleeding of the tongue. Victims comprised 45 males and 24 females, ranging in age from 1 to 95 years old. Sixty-four cases (93%) involved severely charred bodies, while the remaining five bodies displayed slight burns. Factors studied were age, sex, posture of the body at the scene of the fire, degree of burn injury and carboxyhemoglobin (CO-Hb) levels in blood. CO-Hb level proved to be the only factor relevant to intramuscular bleeding of the tongue. Of 69 autopsy cases, 23 (33%) demonstrated intramuscular bleeding of the tongue (13 cases of slight bleeding, ten cases of severe bleeding). Low concentrations of CO-Hb (fire victims. The burned regions of the body in the early stage of the fire process were unclear due to severe charring in most victims. However, asphyxiation due to neck compression is known to often induce intramuscular bleeding of the tongue. Lack of skin elasticity following burns, particularly in the neck, might act in a similar manner to asphyxial neck compression. In conclusion, intramuscular bleeding of the tongue in fire victims may occur as a vital reaction to burns.

    Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunately impossible to achieve through the asynchronous exchange of classical and quantum messages. Perfect security can nonetheless be achieved if each party splits into two agents exchanging classical information at times and locations satisfying strict relativistic constraints. A relativistic multiround protocol to achieve this was previously proposed and used to implement a 2-millisecond commitment time. Much longer durations were initially thought to be insecure, but recent theoretical progress showed that this is not so. In this Letter, we report on the implementation of a 24-hour bit commitment solely based on timed high-speed optical communication and fast data processing, with all agents located within the city of Geneva. This duration is more than 6 orders of magnitude longer than before, and we argue that it could be extended to one year and allow much more flexibility on the locations of the agents. Our implementation offers a practical and viable solution for use in applications such as digital signatures, secure voting and honesty-preserving auctions.

    Full Text Available ABSTRACT: The skin shelters vast micro biota, which could penetrate more internal, layers during the medicine application through parenteral via, therefore the importance of antisepsis for this procedure. We aimed to identify the application of antisepsis through intravenous (IV and intramuscular (IM via for medicine administration as measures for the infection prevention. Descriptive study, accomplished with a nursing team, in eight units from an educational hospital in Goiânia’s district. The data was obtained through observation and filling out the check-list. We observed 212 professionals. As far as the administration via, 19,8% of the procedures were accomplished through direct IV via, 72,6% through IV via with an already installed system and 7,6% through IM via. Most of the professionals, 79,2%, did not wash their hands before accomplishing the procedure. From the 154 medications done in the venous system already installed, the disinfection of the rubber injector was not accomplished in 47 (30,5%. As far as the antisepsis, 72,4% of the medications were accomplished through IV via and 27,6% through IM via, but spite the use of the antiseptic in all the situations, only in 40,5% of the IV injections and in 37,5% of the IM were done five or more movements in the same way with soaked cotton with alcohol at 70%, which is the extolled procedure for the accomplishment for the skin antisepsis. After the antisepsis, 25 professionals touched the place, contaminating it, of these just 13 (52,0% made new antisepsis, therefore, there was recontamination in 12 situations. The data reveals that: necessary measures for the infection prevention in the medicine through parenteral via are not always adopted, representing a challenge for the permanent education and for the infection control at the hospital in study.

    Compliance to osteoporosis treatment with oral bisphosphonates is very poor. Intermittent intravenous bisphosphonate is a useful alternative, but this route is not readily available. Neridronate, a nitrogen-containing bisphosphonate that can be given intramuscularly (IM), was tested in a phase 2 clinical trial in 188 postmenopausal osteoporotic women randomized to IM treatment with 25 mg neridronate every 2 weeks, neridronate 12.5 or 25 mg every 4 weeks, or placebo. All patients received calcium and vitamin D supplements. The patients were treated over 12 months with 2-year posttreatment follow-up. After 12-month treatment, all three doses were associated with significant bone mineral density (BMD) increases at both the total hip and spine. A significant dose-response relationship over the three doses was observed for the BMD changes at the total hip but not at the spine. Bone alkaline phosphatase decreased significantly by 40-55% in neridronate-treated patients, with an insignificant dose-response relationship. Serum type I collagen C-telopeptide decreased by 58-79%, with a significant dose-response relationship (P < 0.05). Two years after treatment discontinuation, BMD declined by 1-2% in each dose group, with values still significantly higher than baseline at both the spine and the total hip. Bone turnover markers progressively increased after treatment discontinuation, and on the second year of follow-up the values were significantly higher than pretreatment baseline. The results of this study indicate that IM neridronate might be of value for patients intolerant to oral bisphosphonates and unwilling or unable to undergo intravenous infusion of bisphosphonates.

  5. Intramuscular architecture of the autochthonous back muscles in humans.

    Many training concepts take muscle properties such as contraction speed or muscle topography into account to achieve an optimal training outcome. Thus far, the internal architecture of muscles has largely been neglected, although it is well known that parameters such as pennation angles or the lengths of fascicles but also the proportions of fleshy and tendinous fascicle parts have a major impact on the contraction behaviour of a muscle. Here, we present the most detailed description of the intramuscular fascicle architecture of the human perivertebral muscles available so far. For this, one adult male cadaver was studied. Our general approach was to digitize the geometry of each fascicle of the muscles of back proper (Erector spinae) - the Spinalis thoracis, Iliocostalis lumborum, Longissimus thoracis and the Multifidus thoracis et lumborum - and of the deep muscles of the abdomen - Psoas minor, Psoas major and Quadratus lumborum - during a layerwise dissection. Architectural parameters such as fascicle angles to the sagittal and the frontal planes as well as fascicle lengths were determined for each fascicle, and are discussed regarding their consequences for the function of the muscle. For example, compared with the other dorsovertebral muscles, the Longissimus thoracis can produce greater shortening distances because of its relatively long fleshy portions, and it can store more elastic energy due to both its relatively long fleshy and tendinous fascicle portions. The Quadratus lumborum was outstanding because of its many architectural subunits defined by distinct attachment sites and fascicle lengths. The presented database will improve biomechanical models of the human trunk by allowing the incorporation of anisotropic muscle properties such as the fascicle direction into finite element models. This information will help to increase our understanding of the functionality of the human back musculature, and may thereby improve future training concepts.

    Ataxia telangiectasia (A-T) is an autosomal recessive disease characterized mainly by progressive cerebellar ataxia, oculocutaneous telangiectasia, and immunodeficiency. This disease is caused by mutations of the ataxia telangiectasia mutated (Atm) gene. More than 500 Atm mutations that are responsible for A-T have been identified so far. However, there have been very few A-T cases reported in China, and only two Chinese A-T patients have undergone Atm gene analysis. In order to systemically investigate A-T in China and map their Atm mutation spectrum, we recruited eight Chinese A-T patients from six unrelated families nationwide. Using direct sequencing of genomic DNA and the multiplex ligation-dependent probe amplification, we identified twelve pathogenic Atm mutations, including one missense, four nonsense, five frameshift, one splicing, and one large genomic deletion. All the Atm mutations we identified were novel, and no homozygous mutation and founder-effect mutation were found. These results suggest that Atm mutations in Chinese populations are diverse and distinct largely from those in other ethnic areas.

    Papillary squamous cell carcinoma (PSCC) is a distinct histological subtype of oral squamous cell carcinoma (SCC), described in both dogs and man. In dogs, PSCC has long been considered a malignant oral tumour of very young animals, but it has recently been reported to occur in adult dogs as well. The aim of this study was to describe the major clinicopathological characteristics of canine oral PSCC (COPSCC). Twelve dogs diagnosed with COPSCC were included in this retrospective study (1990-2012). The majority (75%) of the dogs were >6 years of age (median age 9 years). All tumours were derived from the gingiva of dentate jaws, with 66.7% affecting the rostral aspects of the jaws. The gross appearance of the lesions varied, with one having an intraosseous component only. The majority (91.7%) of the tumours were advanced lesions (T2 and T3), but no local or distant metastases were noted. Microscopically, two patterns were seen: (1) invasion of bone forming a cup-shaped indentation in the bone or a deeply cavitating cyst within the bone (cavitating pattern), (2) histologically malignant growth, but lack of apparent bone invasion (non-cavitating pattern). The microscopical appearance corresponded to imaging findings in a majority of cases, with cavitating forms presenting with a cyst-like pattern of bone loss or an expansile mass on imaging and non-cavitating forms showing an infiltrative pattern of bone destruction on imaging. These features suggest two distinct biological behaviours of COPSCC.

    Twelve cultivars of Elatior begonia (Begonia X hiemalis Fotsch.) were exposed to O/sub 3/ at 25 and 50 pphM. The 'Schwabenland' group, 'Whisper 'O' Pink', and 'Improved Krefeld Orange' were the most sensitive, whereas 'Ballerina', 'Mikkell Limelight', and 'Turo' were the least sensitive. 'Rennaisance', 'Heirloom' 'Nixe', and 'Fantasy' were intermediate in sensitivity. The dry weight of foliage (stems plus leaves) of 9 cultivars exposed to O/sub 3/ was significantly less than that of control plants. Ozone at 25 and 50 pphM inhibited flower growth (including peduncles) and development in 4 and 8 of the 12 cultivars, respectively. Differences in flower weight ranged from 43 to 105% of the control at 25 pphM and from 25 to 98% of the control at 50 pphM, depending on cultivar. 1 table.

    Longitudinal integrated clerkships (LICs) involve learners spending an extended time in a clinical setting (or a variety of interlinked clinical settings) where their clinical learning opportunities are interwoven through continuities of patient contact and care, continuities of assessment and supervision, and continuities of clinical and cultural learning. Our twelve tips are grounded in the lived experiences of designing, implementing, maintaining, and evaluating LICs, and in the extant literature on LICs. We consider: general issues (anticipated benefits and challenges associated with starting and running an LIC); logistical issues (how long each longitudinal experience should last, where it will take place, the number of learners who can be accommodated); and integration issues (how the LIC interfaces with the rest of the program, and the need for evaluation that aligns with the dynamics of the LIC model). Although this paper is primarily aimed at those who are considering setting up an LIC in their own institutions or who are already running an LIC we also offer our recommendations as a reflection on the broader dynamics of medical education and on the priorities and issues we all face in designing and running educational programs.

  10. Commercializing Government-sponsored Innovations: Twelve Successful Buildings Case Studies

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies.

  11. The strong coupling regime of twelve flavors QCD

    2012-01-01

    We summarize the results recently reported in Ref.[1] [A. Deuzeman, M.P. Lombardo, T. Nunes da Silva and E. Pallante,"The bulk transition of QCD with twelve flavors and the role of improvement"] for the SU(3) gauge theory with Nf=12 fundamental flavors, and we add some numerical evidence and theoretical discussion. In particular, we study the nature of the bulk transition that separates a chirally broken phase at strong coupling from a chirally restored phase at weak coupling. When a non-improved action is used, a rapid crossover is observed at small bare quark masses. Our results confirm a first order nature for this transition, in agreement with previous results we obtained using an improved action. As shown in Ref.[1], when improvement of the action is used, the transition is preceded by a second rapid crossover at weaker coupling and an exotic phase emerges, where chiral symmetry is not yet broken. This can be explained [1] by the non hermiticity of the improved lattice Transfer matrix, arising from the c...

    The influence of three cooking methods (stewing, microwaving and Aluminium (Al) foil-baking) was evaluated on the content of intramuscular lipid and the composition of intramuscular fatty acids of Hyla rabbit. The percentage of intramuscular lipid in cooked-longissimus dorsi (LD) (dry weight %) were in the order mentioned below: microwaving > foil-baking > stewing. All treated samples showed decrease in the proportion of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA), whilst increase in the proportion of saturated (SFA) and n-6/n-3 value during processing. All of the cooked samples had the n-6/n-3 ratio within the recommended range (5-10). By the analysis of partial least squares regression (PLSR), the microwaving treatment was better to keep the stability of unsaturated fatty acids (UFA), whilst the long-time Al foil-baking did the most serious damage to UFA, especially the PUFA. In addition, the heating method showed greater influence on the samples than the processing time. The shorter processing time was better to retain the intramuscular PUFA of Hyla rabbit, especially the LC-PUFAs (C20-22). Considering all the factors, microwaving showed the superiority in reserving the composition of intramuscular fatty acids of Hyla rabbit.

    The purpose of this study was to compare the effectiveness of intramuscular and intranasal midazolam used as a premedication before intravenous conscious sedation. Twenty-three children who were scheduled to receive dental treatment under intravenous sedation participated. The patients ranged in age from 2 to 9 years (mean age, 5.13 years) and were randomly assigned to receive a dose of 0.2 mg/kg of midazolam premedication via either intramuscular or intranasal administration. All patients received 50% nitrous oxide and 50% oxygen inhalation sedation and local anesthetic (0.2 mL of 4% prilocaine hydrochloride) before venipuncture. The sedation level, movement, and crying were evaluated at the following time points: 10 minutes after drug administration and at the times of parental separation, passive papoose board restraint, nitrous oxide nasal hood placement, local anesthetic administration, and initial venipuncture attempt. Mean ratings for the behavioral parameters of sedation level, degree of movement, and degree of crying were consistently higher but not significant in the intramuscular midazolam group at all 6 assessment points. Intramuscular midazolam was found to be statistically more effective in providing a better sedation level and less movement at the time of venipuncture than intranasal administration. Our findings indicate a tendency for intramuscular midazolam to be more effective as a premedication before intravenous sedation.

    In this study, a hyperspectral imaging system in the spectral region of 400-1000 nm was used for visualization and determination of intramuscular fat concentration in beef samples. Hyperspectral images were acquired for beef samples, and spectral information was then extracted from each single sample from the fat and non-fat regions. The intramuscular fat content was chemically extracted and quantified for the same samples. Chemometrics including analysis of variance (ANOVA) and spectral similarity measures involving spectral angle measure (SAM), and Euclidian distance measure (EDM) were then used to analyze the data. An ANOVA analysis indicates that the two selected spectral variables (e.g., 650.4-736.4 nm) are effective to generate ratio image for visualization of the intramuscular fat distribution in beef. The spectral similarity analysis methods, which is based on the quantifying the spectral similarities by using predetermined endmember spectrum vector, provided comparable results for characterization and detection of intramuscular fat in beef. In term of overall classification accuracy, spectral similarity measure methods outperformed the ratio image of selected bands based on the result of ANOVA analysis. The results demonstrate that proposed technique has a potential for fast and nondestructive determination of intramuscular fat in beef.

    Full Text Available Abstract Intramuscular myxoma is a rare benign soft tissue tumor which may be mistaken for other benign and low-grade malignant myxoid neoplasms. We present the case of a 63-year-old woman with an asymptomatic intramuscular myxoma discovered incidentally on a whole-body F-18 fluorodeoxyglucose (FDG positron emission tomography (PET/computed tomography. PET images showed a mild FDG uptake (maximum standardized uptake value, 1.78 in the left gluteus maximus. Subsequent magnetic resonance (MR imaging revealed a well-defined ovoid mass with homogenous low signal intensity on T1-weighted sequences and markedly high signal intensity on T2-weighted sequences. Contrast-enhanced MR images showed heterogeneous enhancement throughout the mass. The diagnosis of intramuscular myxoma was confirmed on histopathology after surgical excision of the tumor. The patient had no local recurrence at one year follow-up. Our case suggests that intramuscular myxoma should be considered in the differential diagnosis of an oval-shaped intramuscular soft tissue mass with a mild FDG uptake.

    The Brazzaville cancer registry was created in 1996 with the support of the International Agency Research against Cancer (IARC) which is located in Lyon, France. The Brazzaville cancer registry is a registry which is based on population which records new cancer cases occurring in Brazzaville by using Canreg 4.0 Software. Its aim is to supply useful information to fight against cancer to physicians and to decision makers. We conducted this study whose target was to determine the incidence of cancer in Brazzaville during twelve years, from January 1st, 1998 to December 31, 2009. During that period 6,048 new cancer cases were recorded: 3,377 women (55.8%), 2,384 men (39.4%), and 287 children (4.8%) from 0 to 14 years old with an annual average of 504 cases. Middle age to the patient's diagnosis was 49.5 years in female sex and 505.5 years old for male sex. The incidence rate of cancers in Brazzaville was 39.8 or 100.000 inhabitants per year and by sex we observed 49 to female sex and 35.2 for male sex. The first cancers localizations observed to women were in order of frequency: breast, cervix uterine, liver ovaries, hematopoietic system, to men : liver, prostate, hematopoietic system, colon and stomach; to children : retina, kidney, hematopoietic system, liver and bones. These rates are the basis to know the burden of cancer among all pathologies of Brazzaville and the achievement of a national cancer control program.

    Hyperinsulinism and hyperammonemia syndrome has been reported as a cause of moderately severe hyperinsulinism with diffuse involvement of the pancreas. The disorder is caused by gain of function mutations in the GLUD1 gene, resulting in a decreased inhibitory effect of guanosine triphosphate on the glutamate dehydrogenase (GDH) enzyme. Twelve unrelated patients (six males, six females) with hyperinsulinism and hyperammonemia syndrome have been investigated. The phenotypes were clinically heterogeneous, with neonatal and infancy-onset hypoglycemia and variable responsiveness to medical (diazoxide) and dietary (leucine-restricted diet) treatment. Hyperammonemia (90-200 micromol/L, normal carbamylglutamate administration. The patients had mean basal GDH activity (18.3 +/- 0.9 nmol/min/mg protein) not different from controls (17.9 +/- 1.8 nmol/min/mg protein) in cultured lymphoblasts. The sensitivity of GDH activity to inhibition by guanosine triphosphate was reduced in all patient lymphoblast cultures (IC(50), or concentrations required for 50% inhibition of GDH activity, ranging from 140 to 580 nM, compared with control IC(50) value of 83 +/- 1.0 nmol/L). The allosteric effect of ADP was within the normal range. The activating effect of leucine on GDH activity varied among the patients, with a significant decrease of sensitivity that was correlated with the negative clinical response to a leucine-restricted diet in plasma glucose levels in four patients. Molecular studies were performed in 11 patients. Heterozygous mutations were localized in the antenna region (four patients in exon 11, two patients in exon 12) as well as in the guanosine triphosphate binding site (two patients in exon 6, two patients in exon 7) of the GLUD1 gene. No mutation has been found in one patient after sequencing the exons 5-13 of the gene.

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies. 27 refs., 21 figs., 4 tabs.

    Full Text Available Os ácidos graxos são uma importante fonte de energia para exercício de endurance. Os ácidos graxos plasmáticos encontram-se disponíveis para as fibras musculares sob a forma de ácidos graxos associados à albumina ou agregados à molécula de triacilglicerol (TAG encontrada nas lipoproteínas. Entretanto, além dessas fontes plasmáticas, a hidrólise do TAG encontrado no músculo também pode contribuir com a oferta de ácidos graxos durante o exercício de endurance. O objetivo do presente trabalho foi realizar uma extensa revisão da literatura sobre a importância do TAG intramuscular como substrato energético. A revisão da literatura sugere que a contribuição dos estoques endógenos de TAG durante a realização do exercício de endurance é bastante relevante. Além disso, pode-se concluir que uma adaptação induzida pelo treinamento de endurance é o aumento dos estoques intramusculares de TAG. Após o treinamento de endurance, também é observado aumento na capacidade de utilização desses estoques. Apesar de parecer importante, a contribuição do TAG intramuscular ainda é motivo de controvérsia na literatura. Essa discrepância de resultados está relacionada às metodologias empregadas para estimar a sua oxidação no exercício. A fim de esgotar este assunto de maneira apropriada, mais pesquisas, com novos métodos (ex.: utilização de isótopos, ressonância magnética nuclear e microscopia eletrônica, precisam ser conduzidas.Los ácidos grasos son una fuente importante de energía para el ejercicio de endurance.

    Currently available cyanide antidotes must be given by intravenous injection over 5–10 min, making them illsuited for treating many people in the field, as could occur in a major fire, an industrial accident, or a terrorist attack. These scenarios call for a drug that can be given quickly, e.g., by intramuscular injection. We have shown that aquohydroxocobinamide is a potent cyanide antidote in animal models of cyanide poisoning, but it is unstable in solution and poorly absorbed after intramuscular injection. Here we show that adding sodium nitrite to cobinamide yields a stable derivative (referred to as nitrocobinamide) that rescues cyanide-poisoned mice and rabbits when given by intramuscular injection. We also show that the efficacy of nitrocobinamide is markedly enhanced by coadministering sodium thiosulfate (reducing the total injected volume), and we calculate that ∼1.4 mL each of nitrocobinamide and sodium thiosulfate should rescue a human from a lethal cyanide exposure.

    Full Text Available Abscess formation following intramuscular injections is rare and they are most commonly seen in immunocompromised individuals. In this case series we present a cohort of three patients presented to us in a critically ill condition with an abscess due to intramuscular injection. Vancomycin resistant staphylococcus aureus was isolated from all three patients. These patients posed a major challenge to the healthcare system and the treating physician because of the: severity of illness, virulence and resistance of the organism, rarity of the situation, immune state of the patient, and lack of supporting evidence to properly guide management in the use of health resources. To the best of our knowledge, there is no report available in the English literature on vancomycin resistant staphylococcus aureus associated with intramuscular injection abscess.

    Full Text Available BACKGROUND: As an important factor affecting meat quality, intramuscular fat (IMF content is a topic of worldwide concern. Emerging evidences indicate that microRNAs play important roles in adipocyte differentiation. However, miRNAome has neither been studied during porcine intramuscular preadipocyte differentiation, nor compared with subcutaneous preadipocytes. The objectives of this study were to identify porcine miRNAs involved in adipogenesis in primary preadipocytes, and to determine whether intramuscular and subcutaneous adipocytes differ in the expression and regulation of miRNAs. RESULTS: miRNAomes in primary intramuscular and subcutaneous adipocytes during differentiation were first sequenced using the Solexa deep sequencing method. The sequences and relative expression levels of 224 known (98.2% in miRbase 18.0 and 280 potential porcine miRNAs were identified. Fifty-four of them changed in similar pattern between intramuscular vascular stem cells (IVSC and subcutaneous vascular stem cells (SVSC differentiation, such as miR-210, miR-10b and miR-99a. Expression levels of 10 miRNAs were reversely up-or down-regulated between IVSC and SVSC differentiation, 19 were up-or down-regulated only during IVSC differentiation and 55 only during SVSC differentiation. Additionally, 30 miRNAs showed fat-depot specific expression pattern (24 in cells of intramuscular origin and 6 in cells of subcutaneous origin. These adipogenesis-related miRNAs mainly functioned by targeting similar pathways in adipogenesis, obesity and syndrome. CONCLUSION: Comparison of miRNAomes in IVSC and SVSC during differentiation revealed that many different miRNAs are involved in adipogenesis, and they regulate SVSC and IVSC differentiation through similar pathways. These miRNAs may serve as biomarkers or targets for enhancing IMF content, and uncovering their function in IMF development will be of great value in the near future.

    Full Text Available Aims: Pains caused by the invasive actions such as intramuscular injection lead to the physical and mental tensions in the children. Therefore, such pains should be given relief. One of the main priorities in the nursing is to notice methods that reduce pains due to the invasive actions in the children. The aim of this study was to investigate the effects of injection displayed on a doll on the pain intensity due to the intramuscular injection in the preschool children. Materials & Methods: In the randomized controlled clinical trial, 62 kids aged between 4 and 6 years with pharyngitis were studied in the clinic of the health network of Khalil-abad Township in 2015. The intramuscular injection of penicillin 6.3.3 was administrated for the kids. The subjects, selected by simple lottery, were divided into two groups including experimental and control groups (n=31 per group. Data was collected using a demographic characteristic collecting form and Oucher standard pain assessment tool. In experimental group, the kid watching, one intramuscular injection was displayed on a doll by a nurse; then, the kid underwent an intramuscular injection. In control group, the routine injection method was done. Data was analyzed by SPSS 19 software using Mann-Whitney, independent T, and Chi-square tests. Findings: Mean pain intensity after injection in experimental group (3.22±0.90 was significantly lower than control group (4.19±0.83; p<0.001. Conclusion: The injection displayed on a doll before the intramuscular injection might lead to pain reduction in the preschool kids.

    Previous research indicates that metabolism and fiber type of skeletal muscle is related to intramuscular lipid content. It is hypothesized that changes in skeletal muscle gene expression influence adipose tissue development. The objective of this study was to determine differences in the metabolism and intercellular signaling of skeletal muscle fibers within the same muscle group that could be responsible for the initiation of intramuscular adipose tissue development and differentiation. Longissimus dorsi muscle samples were collected from steers ( = 12; 385 d of age; 378 kg BW) grazing wheat pasture. Longissimus muscle samples were dissected under magnification and sorted into 3 categories based on visual stage of adipose tissue development: immature intramuscular adipose tissue (MM), intermediate intramuscular adipose tissue (ME), and mature intramuscular adipose tissue (MA). Additionally, muscle fibers lying adjacent to each intramuscular adipose tissue (IM) category and those not associated with IM tissue were collected and stored separately. Quantitative real-time PCR was used to determine relative fold change in genes involved in metabolism, angiogenesis, formation of extracellular matrix, and intercellular signaling pathways in both LM and IM samples. Gene expression data were analyzed using a GLM that included the fixed effect of tissue. Pearson correlation coefficients were also computed between gene expression in LM and IM tissue samples that were at the same stage of development. and γ mRNA expression were 3.56- and 1.97-fold greater ( development categories. Genes associated with metabolism and angiogenesis in LM tissue showed no differences among stages of development. Myostatin expression did not change in LM tissue; however, expression of and mRNA decreased ( tissue had a strong positive correlation ( ≥ 0.69) with angiogenic growth factors in LM associated with MM IM; however, no correlation was observed in ME or MA IM. These data indicate a

    2006-01-01

    Full Text Available Two cases of fibrous myopathy associated with repeated, long-term intramuscular injections for treatment of chronic temporomandibular joint pain and chronic headache, respectively, are described. Both patients developed severe, function-limiting contractures in upper and lower extremity muscles used as injection sites. In one of the cases, the contractures were painful. Electrophysiological testing, magnetic resonance imaging and muscle biopsy results were all consistent with myopathy and replacement of skeletal muscle with noncontractile fibrous tissue. These cases are presented to increase awareness of fibrous myopathy and to promote surveillance for this serious potential complication of long-term intramuscular injections in chronic headache and other pain patients.

    A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method. Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand, and/or by injecting mannitol into the caudal vein twice daily. Brain tissue was collected at 24, 48 and 72 hours after modeling, and blood was collected through the retinal vein before Evans blue was injected, approximately 1 hour prior to harvesting of brain tissue. Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats. Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees. There was no significant difference between single treatment and combined treatment. Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion, and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection.

    Objective With the same times of injection to compare low-dose intradermal regimen with routine-dose intramuscular inoculation in revaccination of non-responders to hepatitis B vaccine. Methods 40 healthy non-responder children collected by screening were administrated a three-dose revaccination randomly by intramuscular or intradermal route (10 vs 2 g per dose), and regularly tested for serologic markers up to five years. By the end of follow-up, a booster dose (5 μg) was given to those who had lost anti-HBs of ≥10 mIU/mL (seroprotection) and anamnestic response was estimated thereafter. Results All 17 intramuscular and 22 of 23 intradermal children effected seroprotection after revaccination. Intradermal children lost seroprotection over time significantly rapider compared with intramuscular children (Log Rank test, P= 0.029). In year 5, 50% of intramuscular but only 18.2% of intradermal children still maintained seroprotection (P=0.075). 12-14 days after the booster dose, all the eight intramuscular children developed an anamnestic response with anti-HBs titer increasing greater, but two of the 18 intradermal children failed to mount seroprotective level. Conclusion Three-routine-dose intramuscular revaccination was significantly effective than low-dose intradermal one with the same times of injection, especially in long-term immunity. We recommend routine-dose intramuscular protocol in revaccination of non-responders.

    The twelve-hour shift system, first introduced in the U.S. in 1967 to address a nursing shortage, is now the main system of shift rotation used in numerous countries. In recent years, several hospitals in Taiwan have implemented the 12-hour shift model as one initiative to improve the problems of overtime and high turnover rate among nursing staff. Under this model, nurses work only three to four days per week for 12-hour shifts per day. Despite the increase in numbers of days off, there is growing concern that long shift hours may harm both the safety of patients and the well being of the nurses. The aim of the present article is to explain the application of the 12-hour shift system and to review the potential impacts of this model. Benefits of the 12-hour shift system include improving quality of life for nursing staff, reducing the turnover rate, and increasing job satisfaction. Primary concerns regarding this system include patient safety, nurse fatigue, and the potential negative effects on the sleep quality of nurses. These findings may be referenced by policymakers considering the development / implementation of flexible work schedules in Taiwan. The government must set a ceiling on work hours allowed per week and impose limits on overtime in order to prevent burnout in nursing staff.

    It has been suggested that tooth clenching may be associated with local metabolic changes, and is a risk factor for myofascial temporomandibular disorders (M-TMD). This study investigated the effects of experimental tooth clenching on the levels of 5-HT, glutamate, pyruvate, and lactate, as well as on blood flow and pain intensity, in the masseter muscles of M-TMD patients. Fifteen patients with M-TMD and 15 pain-free controls participated. Intramuscular microdialysis was performed to collect 5-HT, glutamate, pyruvate, and lactate and to assess blood flow. Two hours after the insertion of a microdialysis catheter, participants performed a 20-minute repetitive tooth clenching task (50% of maximal voluntary contraction). Pain intensity was measured throughout. A significant effect of group (Ppain intensity (Ppain intensity; or between (2) pyruvate, lactate, and blood flow. This experimental tooth clenching model increased jaw muscle pain levels in M-TMD patients and evoked low levels of jaw muscle pain in controls. M-TMD patients had significantly higher levels of 5-HT than controls and significantly lower blood flow. These 2 factors may facilitate the release of other algesic substances that may cause pain.

    To investigate whether experimental tooth clenching leads to a release of algesic substances in the masseter muscle. Thirty healthy subjects (16 females, 14 males) participated. During two sessions, separated by at least 1 week, intramuscular microdialysis was performed to collect masseter muscle 5-hydroxytryptamine (5-HT) and glutamate as well as the metabolic markers pyruvate and lactate. Two hours after the start of microdialysis, participants were randomized to a 20-min repetitive experimental tooth-clenching task (50% of maximal voluntary contraction) or a control session (no clenching). Pain and fatigue were measured throughout. The Friedman and Wilcoxon tests were used for statistical analyses. No alterations were observed in the concentrations of 5-HT, glutamate, pyruvate, and lactate over time in the clenching or control session, or between sessions at various time points. Pain (P pain and fatigue developed with this experimental tooth-clenching model, but they were not associated with an altered release of 5-HT, glutamate, lactate, or pyruvate. More research is required to elucidate the peripheral release of algesic substances in response to tooth clenching.

Uncontrolled postoperative pain may produce a range of detrimental acute and chronic health consequences and increase mortality and morbidity. Practically, the analgesic efficacy of opioids is typically limited by the development of tolerance to them or by opioid-related side-effects such as nausea, vomiting, sedation or respiratory depression. This study aims to assess the effects of suppository diclofenac on post-herniorrhaphy pain management."n"nMethods: In this prospective double-blind clinical trial, 60 patients who were candidate for the surgical repair of inguinal hernia were divided into two groups. Patients in group A received 100 mg of suppository diclofenac and patients in group B 50 mg of pethidine after the induction of anesthesia and before surgical incision. Postoperative pain assessment was done by an unbiased observer on the arrival of patients in the recovery room, using a 10-cm visual analogue scale (VAS( at 2-hour intervals for 6 hours."n"nResults: Pain relief was similar in the two groups (P=0.3.

    Nonspecific clinical presentations often lead to misdiagnosis of focal cysticercal myositis. This report emphasizes the role of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of solitary intramuscular cysticercosis. Six patients with persistent post-traumatic isolated muscular swelling were treated with analgesic and antibiotics, but the swelling did not subside. Radiographs showed soft tissue swelling with no bony abnormalities. Laboratory markers were inconclusive. Ultrasonographic and magnetic resonance images (MRI) showed typical features of intramuscular cysticercosis. Clinical, radiological, and fundoscopic evaluation of brain and eyes could not isolate any cysticercosis focus in these organs. Patients were treated with 3 weeks albendazole therapy. The identifying sonographic features of intramuscular cysticercosis, as evident from this case series, included an intramuscular elliptical or oval anechoic lesion with echogenic intralesional focus likely to be scolex. Magnetic resonance images showed orientation of the cyst along the direction of muscle fibers with T2W hyperintense signal and post-contrast perilesional enhancement. All patients responded to medical treatment. Cysticercosis may manifest as isolated muscular swelling without neurological or ocular involvement. Clinicians should be aware of this clinical condition to avoid misdiagnosis. Ultrasonography and magnetic resonance imaging are good diagnostic aids to establish soft tissue cysticercosis. (orig.)

    The 12-h brain lithium concentration was measured by lithium-7 magnetic resonance spectroscopy in ten manic-depressive patients receiving daily or alternate-day lithium carbonate treatment. The median dose of lithium carbonate was 800 mg in the daily treatment group and 1200 mg in the alternate......-day group. Median 12-h serum lithium concentration in the two groups was 0.86 mmol l-1 and 0.55 mmol l-1, respectively, while the corresponding concentration in brain was 0.67 mmol l-1 and 0.52 mmol l-1, respectively. The 12-h brain lithium concentration was independent of lithium dosing schedule (multiple...... linear regression), but correlated significantly with the 12-h serum lithium concentration (P = 0.003; B = 0.53, 95% c.l. 0.24-0.82; beta = 0.83). Thus at identical 12-h serum lithium concentrations the 12-h brain lithium concentration is similar with both treatment regimes. As the risk of manic...

    Objective To determine the ability of an intramuscular cobinamide sulfite injection to rapidly reverse the physiologic effects of cyanide toxicity. Background Exposure to cyanide in fires and industrial exposures and intentional cyanide poisoning by terrorists leading to mass casualties is an ongoing threat. Current treatments for cyanide poisoning must be administered intravenously, and no rapid treatment methods are available for mass casualty cyanide exposures. Cobinamide is a cobalamin (vitamin B12) analog with an extraordinarily high affinity for cyanide that is more water-soluble than cobalamin. We investigated the use of intramuscular cobinamide sulfite to reverse cyanide toxicity induced physiologic changes in a sublethal cyanide exposure animal model. Methods New Zealand white rabbits were given 10 mg sodium cyanide intravenously over 60 minutes. Quantitative diffuse optical spectroscopy and continuous wave near infrared spectroscopy monitoring of tissue oxy- and deoxyhemoglobin concentrations were performed concurrently with blood cyanide level measurements and cobinamide levels. Immediately after completion of the cyanide infusion, the rabbits were injected intramuscularly with cobinamide sulfite (n=6) or inactive vehicle (controls, n=5). Results Intramuscular administration led to rapid mobilization of cobinamide and was extremely effective at reversing the physiologic effects of cyanide on oxyhemoglobin and deoxyhemoglobin extraction. Recovery time to 63% of their baseline values in the central nervous system was in a mean of 1032 minutes in the control group and 9 minutes in the cobinamide group with a difference of 1023 minutes (95% confidence interval [CI] 116, 1874 minutes). In muscle tissue, recovery times were 76 and 24 minutes with a difference of 52 minutes (95% CI 7, 98min). Red blood cell cyanide levels returned towards normal significantly faster in cobinamide sulfite-treated animals than in control animals. Conclusions Intramuscular

    Background The use of midazolam for dental care in patients with intellectual disability is poorly documented. The purpose of this study was to determine which method of premedication is more effective for these patients, 0.15 mg/kg of intramuscular midazolam or 0.3 mg/kg of oral midazolam. Material and Methods This study was designed and implemented as a non-randomized retrospective study. The study population was composed of patients with intellectual disability who required dental treatment under ambulatory general anesthesia from August 2009 through April 2013. Patients were administered 0.15 mg/kg of midazolam intramuscularly (Group IM) or 0.3 mg/kg orally (Group PO). The predictor variable was the method of midazolam administration. The outcome variables measured were Observer’s Assessment of Alertness/ Sedation (OAA/S) Scale scores, the level of cooperation when entering the operation room and for venous cannulation, post-anesthetic agitation and recovery time. Results Midazolam was administered intramuscularly in 23 patients and orally in 21 patients. More patients were successfully sedated with no resistance behavior during venous cannulation in Group PO than in Group IM (p=0.034). There were no differences in demographic data and other variables between the groups. Conclusions The results of this study suggest that oral premedication with 0.3 mg/kg of midazolam is more effective than 0.15 mg/kg of midazolam administered intramuscularly, in terms of patient resistance to venous cannulation. If both oral and intramuscular routes of midazolam are acceptable in intellectually disabled patients, the oral route is recommended. Key words:Premedication, midazolam, intellectual disability.

    Postoperative pain is one of the main postoperative adverse outcomes following caesarean section. Its management still remains a challenge especially in a low resource setting. To compare the efficacy of intramuscular pentazocine alone and combined intramuscular pentazocine with diclofenac for pain relief within 24 hours after caesarean section. This was a double blind randomized control study of post caesarean section pain management of 140 participants between April and December, 2015 at the Federal Teaching hospital, Abakaliki. Inclusion criteria involved consenting and low risk parturients who had caesarean section under spinal anaesthesia. The participants were randomly grouped into Pentazocine-Placebo (PP) group and Pentazocine-Diclofenac (PD) group. The PP group received pentazocine 30 mg every 4 hours for 24 hours and 3 milliliters of water for injection as placebo 12 hourly for 24 hours while the PD group received pentazocine 30 mg every 4 hours and diclofenac 75 mg every 12 hours for 24 hours. The level of pain control was assessed using the Visual Analog Scale (VAS). The data was analysed with IBM SPSS version 20.0. The level of significance was set at section analgesia achieved better pain relief, faster onset of postoperative ambulation, bowel sound auscultation and oral feeding than the use of PP (p-value ≤0.002). However, the use of PD is more expensive than PP (p-value =0.0001). There was no difference between the two groups of participants on the passage of flatus and duration of hospital stay (p-value≥0.05). The use of PP was associated with more maternal side effects (p-value=0.009). There was no difference on the level of satisfaction between the two groups of participants (p-value≥0.05). The use of PD for post caesarean section analgesia is more effective in achieving a satisfactory pain relief and has less side effects.

The objective of this study was to confirm the efficacy of rapid-acting IM olanzapine 10 mg was greater than IM placebo in patients with exacerbation of schizophrenia with acute psychotic agitation by comparing changes from baseline to 2 hours after the first IM injection, as measured by the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC total score. Methods We conducted a placebo-controlled, randomized, double-blind, parallel-group study in Japanese patients diagnosed with schizophrenia according to the diagnostic criteria specified in the DSM-IV-TR. Patients were randomized to 2 treatment groups: IM olanzapine (10 mg or IM placebo. The primary efficacy outcome was the change in PANSS-EC from baseline to 2 hours after the first IM injection. Treatment groups were compared with an analysis of variance model which included treatment and site as factors. During the 24-hour treatment period, safety was assessed by clinical examination and laboratory investigations, electrocardiograms, extrapyramidal symptoms scales, and recording spontaneously reported adverse events. Results Of the 91 randomized patients, 90 patients (45 IM olanzapine-group; 45 IM placebo-group were in the full analysis set. The mean change of PANSS-EC total score from baseline to 2 hours after the first IM injection (mean±standard deviation was −9.2±4.5 for the IM olanzapine group and −2.8±5.6 for the IM placebo group. The difference between treatment groups was statistically significant (p Conclusion The efficacy of IM olanzapine 10 mg in patients with exacerbation of schizophrenia with acute psychotic agitation was greater than IM placebo in the primary efficacy measure, PANSS-EC. Intramuscular olanzapine 10 mg was shown to be generally safe and tolerable, and could be a new option for treatment

    Full Text Available Abstract Artesunate (AS is a clinically versatile artemisinin derivative utilized for the treatment of mild to severe malaria infection. Given the therapeutic significance of AS and the necessity of appropriate AS dosing, substantial research has been performed investigating the pharmacokinetics of AS and its active metabolite dihydroartemisinin (DHA. In this article, a comprehensive review is presented of AS clinical pharmacokinetics following administration of AS by the intravenous (IV, intramuscular (IM, oral or rectal routes. Intravenous AS is associated with high initial AS concentrations which subsequently decline rapidly, with typical AS half-life estimates of less than 15 minutes. AS clearance and volume estimates average 2 - 3 L/kg/hr and 0.1 - 0.3 L/kg, respectively. DHA concentrations peak within 25 minutes post-dose, and DHA is eliminated with a half-life of 30 - 60 minutes. DHA clearance and volume average between 0.5 - 1.5 L/kg/hr and 0.5 - 1.0 L/kg, respectively. Compared to IV administration, IM administration produces lower peaks, longer half-life values, and higher volumes of distribution for AS, as well as delayed peaks for DHA; other parameters are generally similar due to the high bioavailability, assessed by exposure to DHA, associated with IM AS administration (> 86%. Similarly high bioavailability of DHA (> 80% is associated with oral administration. Following oral AS, peak AS concentrations (Cmax are achieved within one hour, and AS is eliminated with a half-life of 20 - 45 minutes. DHA Cmax values are observed within two hours post-dose; DHA half-life values average 0.5 - 1.5 hours. AUC values reported for AS are often substantially lower than those reported for DHA following oral AS administration. Rectal AS administration yields pharmacokinetic results similar to those obtained from oral administration, with the exceptions of delayed AS Cmax and longer AS half-life.

A total of 35 different hydrocarbons were identified in this study. Some differences were found in the levels of branched, cyclical and unsaturated hydrocarbons as a function of the diet of the pigs (3-hexyl-1,1-dimethyl cyclopentane, p<0.05; 3-octadecene, p<0.01; neophytadiene, p<0.001; 1-ethylundecyl benzene, p<0.01; cyclohexadecane, p<0.001; cyclotriacontane, p<0.05). However, the genotype had a limited effect in the level of branched hydrocarbons found. The study of branched hydrocarbons in intramuscular fat from dry-cured Iberian ham allows differentiation between the pigs management systems.

    The patient was a 51-year-old male with a 3-year history of a slow-growing, asymptomatic, subcutaneous mass in the left temporal region. Magnetic resonance imaging revealed a well-defined extracranial lesion with heterogeneous enhancement and without invasion of the skull. A variety of soft tissue tumors were included in the differential diagnosis. The patient underwent total resection of the tumor, and a diagnosis of intramuscular myxoma was confirmed histologically. There was no evidence of recurrence at 6-month follow-up. The present case is the first characterization of the radiological appearance of intramuscular myxoma in the temporal muscle. I emphasize that increased awareness of this rare lesion and a careful clinical and radiological preoperative assessment are crucial in determining an appropriate treatment strategy for patients with a soft tissue tumor of the head.

    Full Text Available The impact of feeding CLA has been thoroughly investigated in pigs, and Thiel- Cooper et al. (2001, Ostrowska et al. (2003, Lo Fiego et al. (2004, found that CLA modifies lipid fatty acid profile, negatively affecting some nutritional lipid indexes. So far,much less attention has been paid to rabbits. Recently, Corino et al. (2003 have shown that supplementing rabbit diets with CLA has limited effect on the chemical composition of meat and at a high slaughter weight reduces intramuscular fat content. The present research has been carried out to evaluate the effect of dietary CLA supplementation on cis-9, trans-11 and trans-10,cis-12- C18:2 isomers content, and on fatty acid composition of rabbit intramuscular lipids.

    Although limb swelling is a well-known complication of vaccination, its rarity and wide band of differential diagnosis of limb swelling make it a diagnostic challenge. In this case report, we describe three cases of vaccine-induced myositis with intramuscular sterile abscess formation in patients with limb swelling and their magnetic resonance imaging and ultrasonography findings. Both radiologists and clinicians should be familiar with this rare entity, its clinical and imaging spectrum, and follow-up strategies. (orig.)

    The objective of this study was to quantify intramuscular tenderness variation within four muscles from the beef round: biceps femoris (BF), semitendinosus (ST), semimembranosus (SM), and adductor (AD). At 48 h postmortem, the BF, ST, SM, and AD were dissected from either the left or right side of ten carcasses, vacuum packaged, and aged for an additional 8 d. Each muscle was then frozen and cut into 2.54-cm-thick steaks perpendicular to the long axis of the muscle. Steaks were broiled on electric broilers to an internal temperature of 71 degrees C. Location-specific cores were obtained from each cooked steak, and Warner-Bratzler shear force was evaluated. Definable intramuscular shear force variation (SD = 0.56 kg) was almost twice as large as between-animal shear force variation (SD = 0.29 kg) and 2.8 times as large as between-muscle variation (SD = 0.20 kg). The ranking of muscles from greatest to least definable intramuscular shear force variation was BF, SM, ST, and AD (SD = 1.09, 0.72, 0.29, and 0.15 kg, respectively). The BF had its lowest shear force values at the origin (sirloin end), intermediate shear force values at the insertion, and its highest shear force values in a middle region 7 to 10 cm posterior to the sirloin-round break point (P 0.05). These data indicate that definable intramuscular tenderness variation is substantial and could be used to develop alternative fabrication and(or) merchandising methods for beef round muscles.

  4. Optimization of mucosal responses after intramuscular immunization with integrase defective lentiviral vector.

    Directory of Open Access Journals (Sweden)

    Alessandra Rossi

    Full Text Available Many infectious agents infiltrate the host at the mucosal surfaces and then spread systemically. This implies that an ideal vaccine should induce protective immune responses both at systemic and mucosal sites to counteract invasive mucosal pathogens. We evaluated the in vivo systemic and mucosal antigen-specific immune response induced in mice by intramuscular administration of an integrase defective lentiviral vector (IDLV carrying the ovalbumin (OVA transgene as a model antigen (IDLV-OVA, either alone or in combination with sublingual adjuvanted OVA protein. Mice immunized intramuscularly with OVA and adjuvant were compared with IDLV-OVA immunization. Mice sublingually immunized only with OVA and adjuvant were used as a positive control of mucosal responses. A single intramuscular dose of IDLV-OVA induced functional antigen-specific CD8+ T cell responses in spleen, draining and distal lymph nodes and, importantly, in the lamina propria of the large intestine. These results were similar to those obtained in a prime-boost regimen including one IDLV immunization and two mucosal boosts with adjuvanted OVA or vice versa. Remarkably, only in groups vaccinated with IDLV-OVA, either alone or in prime-boost regimens, the mucosal CD8+ T cell response persisted up to several months from immunization. Importantly, following IDLV-OVA immunization, the mucosal boost with protein greatly increased the plasma IgG response and induced mucosal antigen-specific IgA in saliva and vaginal washes. Overall, intramuscular administration of IDLV followed by protein boosts using the sublingual route induced strong, persistent and complementary systemic and mucosal immune responses, and represents an appealing prime-boost strategy for immunization including IDLV as a delivery system.

    Background There is an increasing interest in alternative implantation sites to the liver for islet transplantation. Intramuscular implantation has even been tested clinically. Possibilities to monitor β-cell mass would be of huge importance not only for the understanding of islet engraftment but also for the decision of changing the immunosuppressive regime. We have therefore evaluated the feasibility of quantifying intramuscular β-cell mass using the radiolabeled glucagon like peptide-1 receptor agonist DO3A-VS-Cys40-Exendin-4. Methods One hundred to 400 islets were transplanted to the abdominal muscle of nondiabetic mice. After 3 to 4 weeks, 0.2 to 0.5 MBq [177Lu]DO3A-VS-Cys40-Exendin-4 was administered intravenously. Sixty minutes postinjection abdominal organs and graft bearing muscle were retrieved, and the radioactive uptake measured in a well counter within 10 minutes. The specific uptake in native and transplanted islets was assessed by autoradiography. The total insulin-positive area of the islet grafts was determined by immunohistochemistry. Results Intramuscular islet grafts could easily be visualized by this tracer, and the background uptake was very low. There was a linear correlation between the radioactivity uptake and the number of transplanted islets, both for standardized uptake values and the total radiotracer uptake in each graft (percentage of injected dose). The quantified total insulin area of surviving β cells showed an even stronger correlation to both standardized uptake values (R = 0.96, P = 0.0002) and percentage of injected dose (R = 0.88, P = 0.0095). There was no correlation to estimated α cell mass. Conclusions [177Lu]DO3A-VS-Cys40-Exendin-4 could be used to quantify β-cell mass after experimental intramuscular islet transplantation. This technique may well be transferred to the clinical setting by exchanging Lutetium-177 radionuclide to a positron emitting Gallium-68.

    Hamstring injury with intramuscular tendon involvement is regarded as a serious injury with a delay in return to play (RTP) of more than 50 days and reinjury rates up to 63%. However, this reputation is based on retrospective case series with high risk of bias. Determine whether intramuscular tendon involvement is associated with delayed RTP and elevated rates of reinjury. MRI of male athletes with an acute hamstring injury was obtained within 5 days of injury. Evaluation included standardised MRI scoring and scoring of intramuscular tendon involvement. Time to RTP and reinjury rate were prospectively recorded. Out of 70 included participants, intramuscular tendon disruption was present in 29 (41.4%) injuries. Injuries without intramuscular tendon disruption had a mean time to RTP of 22.2±7.4 days. Injuries with <50%, 50%-99% and 100% disruption of tendon cross-sectional area had a mean time to RTP of 24.0±9.7, 25.3±8.6 and 31.6±10.9 days, respectively. Injuries with full-thickness disruption took longer to RTP compared with injuries without disruption (p=0.025). Longitudinal intramuscular tendon disruption was not significantly associated with time to RTP. Waviness was present in 17 (24.3%) injuries. Mean time to RTP for injuries without and with waviness was 22.6±7.5 and 30.2±10.8 days (p=0.014). There were 11 (15.7%) reinjuries within 12 months, five (17.2%) in the group with intramuscular tendon disruption and six (14.6%) in the group without intramuscular tendon disruption. Time to RTP for injuries with full-thickness disruption of the intramuscular tendon and waviness is significantly longer (by slightly more than 1 week) compared with injuries without intramuscular tendon involvement. However, due to the considerable overlap in time to RTP between groups with and without intramuscular tendon involvement, its clinical significance for the individual athlete is limited. © Article author(s) (or their employer(s) unless otherwise stated in the text

  8. How extreme is extreme hourly precipitation?

    2016-04-01

    The importance of accurate representation of precipitation at fine time scales (e.g., hourly), directly associated with flash flood events, is crucial in hydrological design and prediction. The upper part of a probability distribution, known as the distribution tail, determines the behavior of extreme events. In general, and loosely speaking, tails can be categorized in two families: the subexponential and the hyperexponential family, with the first generating more intense and more frequent extremes compared to the latter. In past studies, the focus has been mainly on daily precipitation, with the Gamma distribution being the most popular model. Here, we investigate the behaviour of tails of hourly precipitation by comparing the upper part of empirical distributions of thousands of records with three general types of tails corresponding to the Pareto, Lognormal, and Weibull distributions. Specifically, we use thousands of hourly rainfall records from all over the USA. The analysis indicates that heavier-tailed distributions describe better the observed hourly rainfall extremes in comparison to lighter tails. Traditional representations of the marginal distribution of hourly rainfall may significantly deviate from observed behaviours of extremes, with direct implications on hydroclimatic variables modelling and engineering design.

    Background: Intramuscular manifestations of malignant immuno proliferative diseases (IMMID) are very rare. Purpose: To determine the prevalence and the clinical features of IMMID in a large series of patients, and to analyze their radiological appearances. Material and Methods: Between 1997 and 2007, 20 patients with IMMID (non-Hodgkin lymphoma [NHL], n=14, and myeloma, n=6) were identified. All patients underwent computed tomography (CT). In five cases, magnetic resonance imaging (MRI) was additionally performed. Results: Clinically, 16 patients presented with local pain and soft-tissue swelling. In four patients, IMMID was found incidentally. The most common site was the erector spinae muscle, followed by the iliopsoas and pelvic muscles. In 13 cases of IMMID, diffuse mass-forming muscle infiltration was found. Focal intramuscular masses were identified in seven cases. Conclusion: NHL mostly manifests as diffuse muscle enlargement, whereas myelomas form focal intramuscular masses. Nevertheless, CT and MR appearances are nonspecific and can be misinterpreted as muscle sarcoma or inflammatory disease. Although rare, muscle involvement should be considered in the differential diagnosis of muscle disorders in patients with non-Hodgkin lymphoma and myeloma

    Intramuscular oil injections generating slowly degrading oil-based depots represent a controversial subject in bodybuilding and fitness. However they seem to be commonly reported in a large number of non-medical reports, movies and application protocols for 'site-injections'. Surprisingly the impact of long-term (ab)use on the musculature as well as potential side-effects compromising health and sports ability are lacking in the medical literature. We present the case of a 40 year old male semi-professional bodybuilder with systemic infection and painful reddened swellings of the right upper arm forcing him to discontinue weightlifting. Over the last 8 years he daily self-injected sterilized sesame seed oil at numerous intramuscular locations for the purpose of massive muscle building. Whole body MRI showed more than 100 intramuscular rather than subcutaneous oil cysts and loss of normal muscle anatomy. 2-step septic surgery of the right upper arm revealed pus-filled cystic scar tissue with the near-complete absence of normal muscle. MRI 1 year later revealed the absence of relevant muscle regeneration. Persistent pain and inability to perform normal weight training were evident for at least 3 years post-surgery. This alarming finding indicating irreversible muscle mutilation may hopefully discourage people interested in bodybuilding and fitness from oil-injections. The impact of such chronic tissue stress on other diseases like malignancy remains to be determined.

    In this work, we explored the potential of thermo-sensitive PLGA-PEG-PLGA with sol-gel transition temperature around 32℃ as an intramuscular vaccine delivery system by using ovalbumin as a model antigen. First, in vitro release test showed that the PLGA-PEG-PLGA-deriving hydrogels could release ovalbumin in vitro in a more sustainable way. From fluorescence living imaging, 50-200 mg/mL of PLGA-PEG-PLGA formulations could release antigen in a sustainable manner in vivo, suggesting that the PLGA-PEG-PLGA hydrogel worked as an antigen-depot. Further, the sustainable antigen release from the PLGA-PEG-PLGA hydrogels increased antigen availability in the spleens of the immunized mice. The intramuscular immunization results showed that 50-200 mg/mL of PLGA-PEG-PLGA formulations promoted significantly more potent antigen-specific IgG immune response. In addition, 200 mg/mL of PLGA-PEG-PLGA formulation significantly enhanced the secretion of both Th1 and Th2 cytokines. From in vitro splenocyte proliferation assay, 50-200 mg/mL of PLGA-PEG-PLGA formulations all initiated significantly higher splenocyte activation. These results indicate that the thermo-sensitive and injectable PLGA-PEG-PLGA hydrogels (particularly, 200 mg/mL of PLGA-PEG-PLGA-based hydrogel) own promising potential as an intramuscular vaccine delivery system.

    The 2 antidotes for acute cyanide poisoning in the United States must be administered by intravenous injection. In the out-of-hospital setting, intravenous injection is not practical, particularly for mass casualties, and intramuscular injection would be preferred. The purpose of this study is to determine whether sodium nitrite and sodium thiosulfate are effective cyanide antidotes when administered by intramuscular injection. We used a randomized, nonblinded, parallel-group study design in 3 mammalian models: cyanide gas inhalation in mice, with treatment postexposure; intravenous sodium cyanide infusion in rabbits, with severe hypotension as the trigger for treatment; and intravenous potassium cyanide infusion in pigs, with apnea as the trigger for treatment. The drugs were administered by intramuscular injection, and all 3 models were lethal in the absence of therapy. We found that sodium nitrite and sodium thiosulfate individually rescued 100% of the mice, and that the combination of the 2 drugs rescued 73% of the rabbits and 80% of the pigs. In all 3 species, survival in treated animals was significantly better than in control animals (log rank test, Pcyanide poisoning in 3 clinically relevant animal models of out-of-hospital emergency care.

    Full Text Available To inform healthcare professionals of a rare serious reaction leading to leg amputation following intramuscular injection of iron dextran and report comments for preventing such reactions.A case of leg amputation following intramuscular injection of iron dextran reported to Iranian Pharmacovigilance Center was reviewed. Patient and reaction data was collected by assessing the reported yellow card, patient chart review and interviewing with patient and physicians. World Health Organization definition for serious reactions was used to determine the seriousness of the reaction. Naranjo algorithm was used to determine probability scale. The probability of the reaction was determined based on questionnaire of Schumock et al. The studied case is classified as a rare and serious but preventable reaction induced by intramuscular injection of iron dextran in a 32 year old woman. The probability of the reaction is appeared to be “probable” based on Naranjo algorithm. It seems that Iron dextran could cause serious and life threatening adverse effects. It is necessary for healthcare professionals to be informed of such rare but serious reaction in order to apply preventive actions.

    Spinal epidural abscess is a collection of suppurative material that forms between the dura mater and the ligamentum flavum. If not recognized early and treated correctly, it can lead to life-threatening sepsis. Here we report the case of a female patient, 51 years of age, with difficulty walking and bilateral leg pain after having had degenerative discogenic pain for many years. The patient had occasionally received intramuscular non-steroidal anti-inflammatory drug injections. The current report is that of an unusual case of epidural abscess that formed following multiple dose of intramuscular non-steroidal anti-inflammatory drug over a 1-year period. Hematogenous or direct dissemination is the suspected cause. To prevent serious morbidity and mortality, early diagnosis is essential. Patients with localized back pain who are at risk for developing such epidural spinal abscesses should receive a magnetic resonance imaging scan with contrast enhancement without delay. The existence of predisposing factors such as intramuscular injections should be considered in the assessment of suspected spinal epidural abscess.

    Repeatability is an important consideration for gait analysis data that are being used as an adjunct to clinical decision making. An index of repeatability may be based on a statistical criterion (variance ratio) that reflects similarity of wave forms over a number of identical cycles. The purpose of this study was to use the variance ratio to assess the repeatability of phasic muscle activity recorded with surface and bipolar intramuscular wire electrodes during gait on 10 normal subjects. Variance ratios were calculated using rectified and smoothed electromyographic data recorded simultaneously from the two types of electrodes. Three measures of repeatability (reproducibility, reliability, and constancy--defined as the cycle-to-cycle, run-to-run, and day-to-day repeatability of phasic muscle activity) were used to compare the performance of the two electrode techniques. Results show that the reproducibility and reliability were better for surface electrodes than for intramuscular wire electrodes, and constancy was good for surface electrodes and poor for intramuscular wire electrodes. Repeatability improved with increasing smoothing window lengths but was better for surface electrodes than wire electrodes, irrespective of the smoothing window. This study indicates that surface electrode data represent a more consistent measure of activity of superficial muscles, if comparisons are to be made between gait data from different test days.

  17. A case of human intramuscular adrenal gland transplantation as a cure for chronic adrenal insufficiency.

    Intramuscular endocrine gland transplantation has been well described as it pertains to parathyroid autotransplantation; however, transplantation of the adrenal gland is less well characterized. While adrenal autotransplantation in the setting of Cushing's disease has been described, intramuscular adrenal allotransplantation as a cure for adrenal insufficiency to our knowledge has not been previously carried out. Current treatment for adrenal insufficiency leaves patients without diurnal variation in cortisol release and susceptible to the detrimental effects of chronic hypercortisolism. We describe here the case of a 5-year-old girl with renal failure who had adrenal insufficiency following fulminant meningococcemia that led to requirements for both stress-dose steroid and mineralocorticoid replacement. Ten months after the onset of her disease, she received a simultaneous renal and adrenal gland transplant from her mother. The adrenal gland allograft was morselized into 1 mm(3) segments and implanted into three 2 cm pockets created in her rectus abdominis muscle. Three years after surgery, her allograft remains fully functional, responding well to adrenocorticotropin hormone stimulation and the patient does not require any steroid or mineral-corticoid supplementation. We believe this case represents the first description of successful functional intramuscular adrenal allograft transplantation with long-term follow up as a cure for adrenal insufficiency.

    1995-12-01

    The pharmacokinetic behaviour of amoxicillin/clavulanic acid (4:1) combination was studied after intravenous and intramuscular administration of single doses (25 mg/kg body weight) to 15 turkeys and 15 chickens. The objective was to determine whether there are differences between turkeys and chickens in the disposition kinetics of amoxicillin and clavulanic acid. The plasma concentrations-time data were analysed by compartmental pharmacokinetic and non-compartmental methods. The disposition curves for both drugs after intravenous administration were best described by a two-compartment open model in turkeys and chickens. The apparent volumes of distribution of amoxicillin and clavulanic acid were similar in the two species. The body clearances of amoxicillin and clavulanic acid in turkeys were significantly slower than in chickens. The elimination half-life of amoxicillin was similar in turkeys (1.12 +/-0.09 h) and chickens (1.03 +/-0.11 h) after intravenous administration, but that of clavulanic acid differed significantly (P<0.05) between turkeys (1.12 +/-0.03 h) and chickens (0.98 +/- 0.05 h). After intramuscular administration both drugs had a significantly longer half-life (P<0.05) in turkeys and chickens than that after the intravenous treatment. The bioavailability after the intramuscular injection was high and similar with both drugs, but higher values were obtained for chickens than turkeys.

    In order to determine in vivo intramuscular fat content of pigs' biceps femoris, three methods were compared. Gravimetry and FTIR spectroscopy after total fat extraction from a biopsy (about 400 mg skeletal muscle tissue) and in vivo (1)H NMR spectroscopy after imaging and volume of interest selection were used. Mean values (g fat/100 g fresh tissue) were, respectively, 1·47 ± 0·35 (gravimetry), 1·26 ± 0·33 (FTIR) and 0·51 ± 0·19 (NMR); but NMR-values represented only triglycerides. Within an intramuscular fat range from 1·1 to 2·7 g per 100 g fresh muscle tissue, possible to estimate a calibration line between the in vitro and in vivo data for hybrid piglets of about 18 kg. Repeated in vivo NMR measurements on the same muscle volume showed a mean coefficient of variation of 5·5 ± 2·7%. The coefficient of variation of measurements on different volumes within the same muscle was 14 ± 10%. The mean intramuscular fat content of 18 kg or 100 kg pigs was, respectively, 1·64 ± 0·46 (biceps femoris) and 1·32 ± 0·1 (longissimus dorsi) g per 100 g fresh muscle tissue.

    The sensory attributes and flavor chemistry of grilled beef striploins (M. longissimus lumborum, n = 42) varying widely in marbling from commercial production types typical for Southern Australia were extensively characterized. Striploins from Angus grass-fed yearlings (5.2-9.9% intramuscular fat), Angus grain-finished steers (10.2-14.9%), and Wagyu grass-fed heifers (7.8-17.5%) were evaluated. Inherent differences between samples from grass- and grain-fed Angus cattle were minimal when the intramuscular fat content was above ∼5%. After adjusting for intramuscular fat, Wagyu samples had more intense flavor and higher tenderness and juiciness compared to Angus grass-fed samples. Grilled beef flavor, dairy fat, and sweetness increased with the marbling level, and sourness and astringency decreased. Tenderness and juiciness increased with the marbling level and were correlated with Warner-Bratzler peak force measurements. Trained panel sensory differences in flavor corresponded with increases in aroma volatiles and changes in nonvolatile flavor compounds. Unsaturated fatty acids with potential health benefits (vaccenic, oleic, and rumenic acids) increased with the level of marbling.

    The scientific information service. The CERN library is open 24 hours a day, 365 days a year. So how, you might be wondering, can they improve on that? The answer is in the detail. Although you can already use the library whenever you want, items can only be checked out when the front desk is staffed. A decision taken last week by the Scientific Information Policy Board now means that there will someone at the desk through out CERN's official working hours, with an extra 90 minutes at the end of the day so that people can check out material on their way home. In other words, the library will be open from 8:30 to 19:00, Monday to Friday. The library continues, of course, to be open 24 hours a day, all year round, and services provided via the digital library remain at your disposal day and night: http://library.cern.ch

    The present study investigated the role of peripheral opioid receptors in mustard oil-induced nociceptive behavior and inflammation in the masseter muscles of lightly anesthetized rats. Experiments were carried out on male Sprague-Dawley rats weighing between 300 and 400 g. After initial anesthesia with sodium pentobarbital (40 mg/kg, i.p.), one femoral vein was cannulated and connected to an infusion pump for the intravenous infusion of sodium pentobarbital. The rate of infusion was adjusted to provide a constant level of anesthesia. Mustard oil (MO, 30 microl) was injected into the mid-region of the left masseter muscle via a 30-gauge needle. Intramuscularly-administered morphine significantly reduced shaking behavior but not MO-induced inflammation. Intramuscular pretreatment with naloxone, an opioid receptor antagonist, reversed antinociception produced by intramuscularly-administered morphine, while intracisternal administration of naloxone did not affect the antinociception of peripheral morphine. Pretreatment with d-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP), a mu opioid receptor antagonist, but not naltrindole, a delta opioid receptor antagonist, nor norbinaltorphimine (nor-BNI), a kappa opioid receptor antagonist, reversed intramuscularly-administered morphine-induced antinociception. These results indicate that intramuscularly-administered morphine produces antinociception in craniofacial muscle nociception and that this intramuscularly-administered morphine-induced antinociception is mediated by a peripheral mu opioid receptor. Our observations further support the clinical approach of administering opioids in the periphery for the treatment of craniofacial muscle nociception.

    Full Text Available The study examined the influence of weight, sex and month of hunting on the fatty acid composition of intramuscular and subcutaneous fat from 49 free ranging wild boars hunted in Lithuania during the winter season. A total number of 27 and 25 fatty acids were identified in the intramuscular fat and subcutaneous tissue of wild boars, respectively. The weight of the wild boar had mainly affected only the levels of separate fatty acids both in the intramuscular and subcutaneous fat. Higher levels of saturated fatty acids (SFA were found in the intramuscular and subcutaneous fat of males compared with females. The effect of both weight and sex on the levels of fatty acids was higher in the subcutaneous fat than in the intramuscular fat. Weight, sex and hunting month had no effect on PUFA/SFA and n-6 PUFA/n-3 PUFA ratios in the intramuscular and subcutaneous fat. The atherogenic (AI and thrombogenic (TI indexes and hypocholesterolemic/hypercholesterolemic ratio in subcutaneous fat were more favorable in females compared with males and in the January hunting season than in November and December.

    There are no vaccines or therapeutics currently approved for the prevention or treatment of ebolavirus infection. Previously, a replicon vaccine based on Venezuelan equine encephalitis virus (VEEV) demonstrated protective efficacy against Marburg virus in nonhuman primates. Here, we report the protective efficacy of Sudan virus (SUDV)- and Ebola virus (EBOV)-specific VEEV replicon particle (VRP) vaccines in nonhuman primates. VRP vaccines were developed to express the glycoprotein (GP) of either SUDV or EBOV. A single intramuscular vaccination of cynomolgus macaques with VRP expressing SUDV GP provided complete protection against intramuscular challenge with SUDV. Vaccination against SUDV and subsequent survival of SUDV challenge did not fully protect cynomolgus macaques against intramuscular EBOV back-challenge. However, a single simultaneous intramuscular vaccination with VRP expressing SUDV GP combined with VRP expressing EBOV GP did provide complete protection against intramuscular challenge with either SUDV or EBOV in cynomolgus macaques. Finally, intramuscular vaccination with VRP expressing SUDV GP completely protected cynomolgus macaques when challenged with aerosolized SUDV, although complete protection against aerosol challenge required two vaccinations with this vaccine.

    Air temperature is the main climatological element, with major impact on the earth-atmosphere energy balance. The characteristics of the surface air temperature in locations without meteorological measurements are obtained using spatio-temporal interpolation techniques. Gridded surface meteorological data are essential for evaluating the performance of regional climate models (RCMs), for applying Statistical Downscaling (SD) methods and as input data for hydrological models. In this study we proposed a methodolgy for interpolating hourly surface temperatures. Three gridding methods are compared. A two-step multivariate gridding approach was used. First we interpolated the hourly normal maps, considered as multiannual average (1961-2010), of air temperature for each hour (4 meteorological terms) of a standard year (366 days). In this step, the Residual Kriging method was used with potential predictors derived from DEM and Landcover Corinne. For interpolating the residuals of the regression model we tested 3 gridding methods: Multiquadratic (MQ), Ordinary Kriging (OK) and 3D Kriging (using time as a third dimension). In the second step, we calculated the anomalies of each hour, day, year for the period 1961-2010. The anomalies were interpolated using the same methods applied for gridding regression residuals. The final hourly surface air temperature maps were obtained by summing the maps from first step with the anomlies map. The main data used in this work were the hourly air temperatures of the 4 observation terms (01, 07, 13, 19), measured between 1961-2010 at the weather stations of the Romanian Meteorological Administration. The predictors were derived from SRTM (Shuttle Radar Topography Mission) DEM and from CORINE Land Cover 2000 product. The gridding was performed in a Romanian National Grid (Stereo 70), at 1 km2 spatial resolution, using R language. The study has been financed by the research project Changes in climate extremes and associated impact in

    Opioid-induced hyperalgesia (OIH), increased sensitivity to noxious stimuli after repeated opioid exposures, has been demonstrated in preclinical studies. However, there is no accepted, prospective model of OIH after repeated opioid exposures currently available in humans. This study assessed a potential prospective OIH model. Double-blind intramuscular injections of a short-acting opioid (alfentanil 15 mcg/kg; N=8) were compared to active placebo (diphenhydramine 25 mg; N=3) on cold and pressure pain testing and standard abuse liability measures in eight 10-hour sessions (1 injection/session) over 4 to 5 weeks in healthy, pain-free males. Decreases from session baseline pain threshold (PThr) and tolerance (PTol) were calculated to represent hyperalgesia, and were assessed both within and across sessions. Mean decreases in cold PTol were seen in the alfentanil group at 180 minutes (-3.8 s, ±26.5) and 480 minutes (-1.63 s, ±31.5) after drug administration. There was a trend for differences between conditions on cold PThr hyperalgesia but not for pressure PThr. Alfentanil participants had greater mean ratings on Liking and High visual analog scales at peak effects (30 min), but these scores did not change across sessions. Repeated alfentanil exposures over 4 to 5 weeks resulted in within session decreases in cold pain tolerance from baseline but these differences were not substantially different from diphenhydramine controls. The results did not support the phenomenon of OIH in this model, although definitive conclusions regarding the existence of OIH in humans likely requires a larger sample size or an alternative model.

    In this paper we present a computer-based system that is designed to reduce the number of patient calls in physicians' phone-in hours. Simultaneously it will offer a parallel alternative channel for the patients to listen to their laboratory results. The system requirements were reliability, security and the low costs. The results showed after a two-month test period that the tailored system proved extremely successful. The average time that the physician saved by using this system was over 4 minutes and doctors can leave the messages to the server also outside the phone-in hours.

    Due to the highly technical language in the wage and hour laws and regulations, employers often find that they have unknowingly violated the Fair Labor Standards Act (FLSA). This can occur because employers have improperly classified an employee as exempt or because employers do not realize that certain time should be paid in full. Improperly classifying employees as exempt or failing to compensate nonexempt employees for all time worked can lead to costly lawsuits, audits, or enforcement actions by the Wage and Hour Division of the Department of Labor. This article discusses the most common FLSA exemptions and provides best practices to avoid liability under the FLSA.

  11. Determination of α-tocopherol in pork with high intramuscular fat content

    1996-10-01

    Full Text Available Extraction of α-tocopherol from pork samples with low (3% (LF or high (9% (HF amount of intramuscular fat have been carried out by three different methods, two of them based in saponification plus extraction of α-tocopherol and the other one without saponification. All samples were spiked with five different amount of α-tocopherol prior to analysis. In LF samples, recovery was in the range 85-95% in all cases, with not significant differences between methods. Recovery was much lower in HF samples when using methods which involve prior saponification of muscle samples (50-60%. Changes in KOH concentration did not improve markedly the recovery. The method based on direct extraction provided much better recovery in HF samples (85- 92% and consequently is recommended for samples high in fat.

    Se han utilizado tres métodos de cuantificación de α-tocoferol en muestras de tejido muscular de cerdos con un contenido en grasa intramuscular del 3% (LF y del 9% (HF. Dos de los métodos saponifican la muestra antes de extraer el α-tocoferol, y el tercero utiliza una extracción directa con solventes. Antes del análisis se añadieron cinco cantidades de α-tocoferol en cada caso. La recuperación del α-tocoferol en las muestras de bajo contenido en grasa intramuscular fue en todos los casos alrededor del 85-95%, sin encontrarse diferencias según el método utilizado. En las muestras con alto contenido en grasa intramuscular la recuperación fue mucho menor cuando se utilizaron los métodos que saponifican la muestra (50-60%. Al añadir mayor concentración de KOH no se mejoró sustancialmente la recuperación. El método basado en extracción directa con solventes proporcionó una recuperación superior (85-92% y es por tanto el que se recomienda para muestras con alto contenido en grasa intramuscular.

    The commonest opioid used for pain relief in labour is pethidine (meperidine); however, its effectiveness has long been challenged and the drug has known side effects including maternal sedation, nausea and potential transfer across the placenta to the foetus. Over a third of women receiving pethidine require an epidural due to inadequate pain relief. Epidural analgesia increases the risk of an instrumental vaginal delivery and its associated effects. Therefore, there is a clear need for a safe, effective, alternative analgesic to pethidine. Evidence suggests that remifentanil patient-controlled analgesia (PCA) reduces epidural conversion rates compared to pethidine; however, no trial has yet investigated this as a primary endpoint. We are, therefore, comparing pethidine intramuscular injection to remifentanil PCA in a randomised controlled trial. Women in established labour, requesting systemic opioid pain relief, will be randomised to either intravenously administered remifentanil PCA (intervention) or pethidine intramuscular injection (control) in an unblinded, 1:1 individual randomised trial. Following informed consent, 400 women in established labour, who request systemic opioid pain relief, from NHS Trusts across England will undergo a minimised randomisation by a computer or automated telephone system to either pethidine or remifentanil. In order to balance the groups this minimisation is based on four parameters; parity (nulliparous versus multiparous), maternal age (relief provided by each technique will be recorded every 30 min after time zero, until epidural placement, delivery or transfer to theatre, quantified by Visual Analogue Scale. Incidence of maternal side effects including sedation, delivery mode, foetal distress requiring delivery, neonatal status at delivery and rate of initiation of breastfeeding within the first hour of birth will also be recorded. Maternal satisfaction with her childbirth experience will be determined by a postpartum

    The second questionnaire for scientists and engineers was carried out in 2007, and status of Japanese scientists and engineers were analyzed and reported. A part of the data was reanalyzed from the viewpoint of work life balance. In particular, office/laboratory staying hour and home working hour were analyzed and dependences on various factors were investigated. It was found that these hours depend on gender, marital status, number of child, employment status and age. In addition, the total hours tend to be kept constant regardless of various factors.

    The response speed of ambulance calls is very crucial to rescue patients suffering immediately life threatening conditions. The serious health outcomes might be caused by exposing to extreme heat only several hours before. However, limited evidence is available on this topic. This study aims to examine the hourly association between heat and ambulance calls, to improve the ambulance services and to better protect health. Hourly data on ambulance calls for non-accidental causes, temperature and air pollutants (PM10, NO2, and O3) were collected from Brisbane, Australia, during 2001 and 2007. A time-stratified case-crossover design was used to examine the associations between hourly ambulance calls and temperature during warm season (Nov, Dec, Jan, Feb, and Mar), while adjusting for potential confounders. Stratified analyses were performed for sex and age groups. Ambulance calls peaked at 10am for all groups, except those aged heat-ambulance calls relationships were non-linear for all groups, with thresholds between 27 °C and 31 °C. The associations appeared immediately, and lasted for about 24 h. There were no significant modification effect by sex and age. The findings suggest that hot hourly temperatures (>27 °C) increase the demands of ambulance. This information is helpful to increase the efficiency of ambulance service then save lives, for example, preparing more ambulance before appearance of extremely hot temperature in combination with weather forecast. Also, people should better arrange their time for outdoor activities to avoid exposing to extreme hot temperatures. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2005-09-01

    Full Text Available Abstract For patients who require replacement therapy for primary immunodeficiency, subcutaneous infusions of immunoglobulin G (IgG may be preferable to intravenous infusions for several reasons. However, at present, there is no preparation marketed for use by this route in North America. In this article, we describe the reasons patients have selected this route of therapy and the range of treatment regimens used. Approximately 20% of our patients have chosen the subcutaneous route, mainly because of adverse effects from intravenous (IV infusions or difficulties with venous access. Unit dose regimens using whole bottles of currently available 16% intramuscular preparations or sucrose-containing lyophilized preparations intended for IV use but reconstituted to 15% IgG for subcutaneous administration were individually tailored to each patient. In most cases, self-infusions or home infusions were administered once or twice a week, most commonly requiring two subcutaneous sites and 2 to 3 hours per infusion. On average, patients took 0.18 mL of IgG per kilogram of body weight per site per hour. There were no systemic adverse effects. In patients for whom comparative data were available, trough serum IgG levels were higher with subcutaneous therapy than with IV therapy.

    Studies have shown that intramuscular adipogenesis and fibrogenesis may concomitantly occur in skeletal muscle of beef cattle. Thus, we hypothesized that the discrepancy of intramuscular fat content in beef from Nellore and Angus was associated with differences in intramuscular adipogenesis and fibrogenesis during the finishing phase. To test our hypothesis, longissimus muscle samples of Nellore (n = 6; BW = 372.5 ± 37.3 kg) and Angus (n = 6; BW = 382.8 ± 23.9 kg) cattle were collected for analysis of gene and protein expression, and quantification of intramuscular fat and collagen. Least-squares means were estimated for the effect of Breed and differences were considered at P ≤ 0.05. A greater intramuscular fat content was observed in skeletal muscle of Angus compared to Nellore cattle (P≤0.05). No differences were observed for mRNA expression of lipogenic and lipolytic markers ACC, FAS, FABP4, SERBP-1, CPT-2, LPL, and ACOX (P > 0.05) in skeletal muscle of Nellore and Angus cattle. Similarly, no differences were observed in mRNA expression of adipogenic markers Zfp423, PPARγ, and C/EBPα (P>0.05) However, a greater PPARγ protein content was observed in skeletal muscle of Angus compared to Nellore cattle (P≤0.05). A greater abundance of adipo/fibrogenic cells, evaluated by the PDGFRα content, was observed in skeletal muscle of Angus than Nellore cattle (P≤0.05). No differences in fibrogenesis were observed in skeletal muscle of Angus and Nellore cattle, which is in accordance with the lack of differences in intramuscular collagen content in beef from both breeds (P>0.05). These findings demonstrate that difference in intramuscular fat content is associated with a slightly enhanced adipogenesis in skeletal muscle of Angus compared to Nellore cattle, while no difference in fibrogenesis.

Similarly, no differences were observed in mRNA expression of adipogenic markers Zfp423, PPARγ, and C/EBPα (P>0.05 However, a greater PPARγ protein content was observed in skeletal muscle of Angus compared to Nellore cattle (P≤0.05. A greater abundance of adipo/fibrogenic cells, evaluated by the PDGFRα content, was observed in skeletal muscle of Angus than Nellore cattle (P≤0.05. No differences in fibrogenesis were observed in skeletal muscle of Angus and Nellore cattle, which is in accordance with the lack of differences in intramuscular collagen content in beef from both breeds (P>0.05. These findings demonstrate that difference in intramuscular fat content is associated with a slightly enhanced adipogenesis in skeletal muscle of Angus compared to Nellore cattle, while no difference in fibrogenesis.

  9. Why surface nanobubbles live for hours

    CERN Document Server

    Weijs, Joost H

    2012-01-01

    We present a theoretical model for the experimentally found but counter-intuitive exceptionally long lifetime of surface nanobubbles. We can explain why, under normal experimental conditions, surface nanobubbles are stable for many hours or even up to days rather than the expected microseconds. The limited gas diffusion through the water in the far field, the cooperative effect of nanobubble clusters, and the pinned contact line of the nanobubbles lead to the slow dissolution rate.

  12. Resolving issues concerning Eskdalemuir geomagnetic hourly values

    Directory of Open Access Journals (Sweden)

    S. Macmillan

    2011-02-01

    Full Text Available The hourly values of the geomagnetic field from 1911 to 1931 derived from measurements made at Eskdalemuir observatory in the UK, and available online from the World Data Centre for Geomagnetism at http://www.wdc.bgs.ac.uk/, have now been corrected. Previously they were 2-point averaged and transformed from the original north, east and vertical down values in the tables in the observatory yearbooks. This paper documents the course of events from discovering the post-processing done to the data to the final resolution of the problem. As it was through the development of a new index, the Inter-Hour Variability index, that this post-processing came to light, we provide a revised series of this index for Eskdalemuir and compare it with that from another European observatory. Conclusions of studies concerning long-term magnetic field variability and inferred solar variability, whilst not necessarily consistent with one another, are not obviously invalidated by the incorrect hourly values from Eskdalemuir. This series of events illustrates the challenges that lie ahead in removing any remaining errors and inconsistencies in the data holdings of different World Data Centres.

    From 8.30 to 9.30 p.m. on Saturday, 26 March 2011, the Globe of Science and Innovation will be plunged into darkness to mark CERN's participation in Earth Hour. A growing number of countries and cities across the planet are involved in this global initiative against climate change, which was launched by the WWF in 2007.   The lights on the Globe were switched off for the 2009 Earth Hour event. Along with individuals, companies and tourist attractions in thousands of towns and cities all over the world participating in the fourth annual Earth Hour event, CERN will turn off the lights of the Globe for 60 minutes at 8.30 p.m. on Saturday 26 March. CERN's participation in the initiative is one of several examples of its commitment to respect the environment and keep its ecological footprint to the minimum. A recent example under the green transport heading was the replacement of part of CERN's petrol vehicle fleet with cars running on natural gas with a view to reducing air pollution.

    The expression of inflammatory cytokines and growth factors in surgically repaired lacerated muscles over a 12-week recovery phase was investigated. We hypothesized that these expression levels are influenced by both neural and muscular damage within lacerated muscles. Microarrays were confirmed with reverse transcription-polymerase chain reaction assays and histology of biopsies at the lesion of three simulated lacerated muscle models in 130 adult rats. The lacerated medial gastrocnemius with the main intramuscular nerve branch either cut (DN), crushed but leaving an intact nerve sheath (RN); or preserved intact (PN) were compared. At 4 weeks, DN had a higher number of interleukins up-regulated. DN and RN also had a set of Bmp genes significantly expressed between 2 and 8 weeks (P ≤ 0.05). By 12 weeks, DN had a poorer and slower myogenic recovery and greater fibrosis formation correlating with an up-regulation of the Tgf-β gene family. DN also showed poorer re-innervation with higher mRNA expression levels of nerve growth factor (Ngf) and brain-derived neurotrophin growth factor (Bdnf) over RN and PN. This study demonstrates that the inflammatory response over 12 weeks in lacerated muscles may be directed by the type of intramuscular nerve damage, which can influence the recovery at the lesion site. Inflammatory-related genes associated to the type of intramuscular nerve damage include Gas-6, Artemin, Fgf10, Gdf8, Cntf, Lif, and Igf-2. qPCR also found up-regulation of Bdnf (1-week), neurotrophin-3 (2w), Lif (4w), and Ngf (4w, 8w) mRNA expressions in DN, making them possible candidates for therapeutic treatment to arrest the poor recovery in muscle lacerations (250).

    Objective. Myoelectric prostheses use electromyographic (EMG) signals to control movement of prosthetic joints. Clinically available myoelectric control strategies do not allow simultaneous movement of multiple degrees of freedom (DOFs); however, the use of implantable devices that record intramuscular EMG signals could overcome this constraint. The objective of this study was to evaluate the real-time simultaneous control of three DOFs (wrist rotation, wrist flexion/extension, and hand open/close) using intramuscular EMG. Approach. We evaluated task performance of five able-bodied subjects in a virtual environment using two control strategies with fine-wire EMG: (i) parallel dual-site differential control, which enabled simultaneous control of three DOFs and (ii) pattern recognition control, which required sequential control of DOFs. Main results. Over the course of the experiment, subjects using parallel dual-site control demonstrated increased use of simultaneous control and improved performance in a Fitts’ Law test. By the end of the experiment, performance using parallel dual-site control was significantly better (up to a 25% increase in throughput) than when using sequential pattern recognition control for tasks requiring multiple DOFs. The learning trends with parallel dual-site control suggested that further improvements in performance metrics were possible. Subjects occasionally experienced difficulty in performing isolated single-DOF movements with parallel dual-site control but were able to accomplish related Fitts’ Law tasks with high levels of path efficiency. Significance. These results suggest that intramuscular EMG, used in a parallel dual-site configuration, can provide simultaneous control of a multi-DOF prosthetic wrist and hand and may outperform current methods that enforce sequential control.

    A divergent selection experiment on intramuscular fat (IMF) was performed in rabbits. The aim of this study is to estimate the response to selection, the correlated responses in carcass and meat quality traits, and their genetic parameters. Selection criterion was the averaged phenotypic value of IMF measured at 9 wk of age in 2 full-sibs of the candidate. Traits considered were IMF, BW, chilled carcass weight, reference carcass weight, scapular and perirenal fat weights, carcass and meat color, pH, protein and fatty acid composition of meat. Total direct response to selection for IMF was 2.6 phenotypic SD of the trait, around 5% of the mean (1.09 g/100 g) per generation, with both lines following a symmetrical trend. Heritability of IMF was high (0.54), and in general, all traits related to carcass fat depots and IMF fatty acid composition showed high heritabilities (dissectible fat of the carcass, 0.70; MUFA percentage, 0.61; PUFA percentage, 0.45; and PUFA:SFA ratio, 0.42), except SFA percentage (0.09). The other carcass and meat quality traits showed moderate to low heritabilities. Intramuscular fat and dissectible fat percentage showed a low genetic correlation (0.34). Intramuscular fat was positively correlated with MUFA percentage (0.95) and negatively correlated with PUFA percentage (-0.89) and PUFA:SFA ratio (-0.98), corroborated with high correlated responses to selection. The rest of the traits did not show any substantial correlated response except protein content, which was greater in the high-IMF line than in the low-IMF line.

    Some pharmacokinetic parameters of an ampicillin/sulbactam (2:1) combination were studied in six goats, after intravenous and intramuscular injection at a single dosage of 20 mg/kg bodyweight (13.33 mg/kg of sodium ampicillin and 6.67 mg/kg of sodium sulbactam). The drugs were distributed according to an open two-compartment model. The apparent volumes of distribution calculated by the area method of ampicillin and sulbactam were 0.34 +/- 0.04 l/kg and 0.45 +/- 0.15 l/kg, respectively, and the total body clearances were 0.72 +/- 0.11 and 0.38 +/- 0.07 l/kg.h. The half-lives of ampicillin after intravenous and intramuscular administration were 0.32 +/- 0.04 h and 0.71 +/- 0.14 h, respectively. For sulbactam the half-lives were 0.79 +/- 0.18 h and 1.13 +/- 0.21 h after administration by the same routes. The bioavailability after intramuscular injection was high and similar for both drugs (98.29% for ampicillin and 101.84% for sulbactam). The mean peak plasma levels of ampicillin (0.43 +/- 0.27 h) and sulbactam (0.34 +/- 0.14 h) were reached at a similar time, and peak concentrations were also similar and non-proportional to the dose of the products administered (11.02 +/- 3.11 mg/l of ampicillin and 9.5 +/- 0.98 mg/l of sulbactam).

    Intramuscular fat (IMF) content is considered to be a key factor that affects the marbling, tenderness, juiciness and lfavor of pork. To investigate the effects of myristic acid (MA) on the differentiation of porcine intramuscular adipocytes, cells were isolated from longissimus dorsi muscle (LDM) and treated with 0, 10, 50 or 100μmol L-1 MA. The results showed that MA signiifcantly promotes the differentiation of intramuscular adipocytes in a dose-dependent manner. MA also led to a parallel increase in the expression of peroxisome proliferator activated receptor-γ(PPARγ) and adipose-related genes, such as glucose transporter 1 (GLUT1), lipoprotein lipase (LPL), adipocyte fatty acid binding protein 4 (FABP4/aP2), fatty acid translocase (FAT), acetyl-CoA carboxylaseα(ACCα), adipose triglyceride lipase (ATGL) and fatty acid synthase (FASN). However, no signiifcant effects of MA were observed on the expression of CAAT enhancer binding protein-α(C/EBPα) or hormone sensitive lipase (HSL). The expression of pyruvate dehydrogenase kinase 4 (PDK4) was increased by MA during the early stages of differentiation (day 1-3). In addition, MA also increased the absolute content of C14 (P<0.001) and saturated fatty acids (SFA) (P<0.05) to varying degrees, but no effects were observed on other fatty acids. These results suggest that MA might be able to enhance the IMF content of pork and increase the accumulation of myristic and myristoleic acid in muscle, which might have beneifcial implications for human health.

    Lipomas are common benign neoplasms consisting of mature fatty tissue. They are usually of roundish or ovoid shape and are situated in a single anatomical region. They most frequently occur on the back and in the extremities. Most lipomas are subcutaneous and require no imaging evaluation. When deep, large and unusual in location, MRI can identify and localise these tumours and is the best exploration to differentiate lipoma and lipo-sarcoma. We describe a case of a patient with an intramuscular lipoma of the biceps brachii.

    We report a case of solitary intramuscular myxoma in a patient with polyostotic fibrous dysplasia and pigmented macules. MR played an important role in the patient's pre-operative evaluation. It has been demonstrated in a review of the literature that a definite relationship exists between myxoma of soft tissues and fibrous dysplasia of the skeleton. Multiple myxomas in a patient with fibrous dysplasia are common and a relationship also exists between myxoma of the soft tissues and the McCune-Albright syndrome. (orig./GDG).

    The objective of this study was to compare the fatty acid (FA) composition of intramuscular fat from the LM of 3 divergent breeds of cattle: Angus (AN, n = 9), Brahman (BR, n = 7), and Romosinuano (RM, n = 11). Cattle were blocked by breed and finished 129 d before slaughter in one year and 157 d in the next year. Longissimus muscle samples were collected from each carcass between the 10th and 13th ribs, trimmed of external fat, frozen in liquid nitrogen, homogenized, and used for fat extraction, using a modified Folch procedure. Extracted fat was analyzed for FA by using a GLC system with an HP-88 capillary column. Fatty acid composition was expressed using both a normalized percentage (%) and gravimetric calculation (mg/g of fresh muscle tissue) in relation to degree of saturation, which was determined using a saturation index (ratio of total SFA to total unsaturated FA). Crude fat determination revealed that LM from AN purebred cattle had the greatest amount of intramuscular fat (7.08%; P = 0.001). Although intramuscular fat of LM from RM contained a reduced percentage of total SFA (P = 0.002) compared with AN, it had the greatest percentage of total PUFA (P < 0.001 and P = 0.020). The percentages of total MUFA were similar among the 3 breeds (P = 0.675). The gravimetric calculation, a measure of actual FA concentration, showed significantly greater concentrations of SFA (26.67 mg/g), MUFA (26.50 mg/g), and PUFA (2.37 mg/g) in LM from AN cattle, as compared with LM from BR and RM cattle (P < 0.001). Interestingly, BR purebreds had the least PUFA concentration (1.49 mg/g; P intramuscular fat content was similar to that of RM (P = 0.924). Regardless of breed, the MUFA proportion was always the greatest (47.58%; P

    The development of effective vaccines has helped to eradicate or control the spread of numerous infectious diseases. However, there are many more diseases that have proved more difficult to eliminate using conventional vaccines. The recent innovation of DNA vaccines may provide a "boost" to the development efforts. While the early efforts of DNA vaccines in the clinic were disappointing, the use of in vivo electroporation has helped to provide some basis for optimism. Now, there are several ongoing clinical studies of vaccines against such diseases as malaria, HIV, hepatitis C, and even various types of cancer. This review will highlight three recently published clinical studies using intramuscular DNA administration with electroporation.

Randomised controlled trial. The South Glasgow University Hospitals NHS Trust. Primigravidae and multigravidae in labour at term (37-42 weeks). Women were randomised in labour to the study (patient-controlled analgesia) or control group (intramuscular). Randomisation was achieved through a random permuted block design stratified by parity. Study group women were given a loading dose of 1.2 mg diamorphine intravenously and then attached to the pump. Control group women received intramuscular diamorphine as per hospital protocol. Participants were also given 3 mg of buccal Stemetil. Data were collected throughout labour and at six postnatal weeks. Analgesia requirements during labour and women's satisfaction with the method of pain relief. Women in the study group (patient-controlled analgesia) used significantly less diamorphine than women in the control group (intramuscular) but were significantly more likely to state that they were very dissatisfied with their use of diamorphine and were significantly more likely to opt out of the trial before the birth of the baby. The majority of women in both groups used other analgesia concurrent with diamorphine such as Entonox, aromatherapy or TENS. Patient-controlled analgesia administration of diamorphine for the relief of pain in labour offers no significant advantages over intramuscular administration. The results also suggest that diamorphine is a poor analgesic for labour pain irrespective of the mode of administration.

  18. GRIN: “GRoup versus INdividual physiotherapy following lower limb intra-muscular Botulinum Toxin-A injections for ambulant children with cerebral palsy: an assessor-masked randomised comparison trial”: study protocol

    Science.gov (United States)

    2014-01-01

    Background Cerebral palsy is the most common cause of physical disability in childhood. Spasticity is a significant contributor to the secondary impairments impacting functional performance and participation. The most common lower limb spasticity management is focal intramuscular injections of Botulinum Toxin-Type A accompanied by individually-delivered (one on one) physiotherapy rehabilitation. With increasing emphasis on improving goal-directed functional activity and participation within a family-centred framework, it is timely to explore whether physiotherapy provided in a group could achieve comparable outcomes, encouraging providers to offer flexible models of physiotherapy delivery. This study aims to compare individual to group-based physiotherapy following intramuscular Botulinum Toxin-A injections to the lower limbs for ambulant children with cerebral palsy aged four to fourteen years. Methods/Design An assessor-masked, block randomised comparison trial will be conducted with random allocation to either group-based or individual physiotherapy. A sample size of 30 (15 in each study arm) will be recruited. Both groups will receive six hours of direct therapy following Botulinum Toxin-A injections in either an individual or group format with additional home programme activities (three exercises to be performed three times a week). Study groups will be compared at baseline (T1), then at 10 weeks (T2, efficacy) and 26 weeks (T3, retention) post Botulinum Toxin-A injections. Primary outcomes will be caregiver/s perception of and satisfaction with their child’s occupational performance goals (Canadian Occupational Performance Measure) and quality of gait (Edinburgh Visual Gait Score) with a range of secondary outcomes across domains of the International Classification of Disability, Functioning and Health. Discussion This paper outlines the study protocol including theoretical basis, study hypotheses and outcome measures for this assessor-masked, randomised

    Full Text Available PURPOSE: To evaluate the effects of fat embolism in organs such as lung and liver. METHODS: Twenty rabbits underwent autologous intramuscular fat grafting in the right thigh after liposuction. The groups were determined according to the postoperative day that occurred in euthanasia: 60, 90 and 120 day. Then, lung and liver were excised and sent to the histopathology laboratory for analysis in search of late injury secondary to a prior event of fat embolism in the tissues. RESULTS: The results showed a change in the macroscopic sample with discoloration of the liver tissue heterogeneously. There were no changes consistent with embolic effect under the microscope. CONCLUSION: The option of performing a technique of fat grafting with a less traumatic surgical procedure can be considered protective against embolic events, with no impact to late embolic events on the tissues.OBJETIVO: Avaliar a repercussão da embolia gordurosa em órgãos como pulmão e fígado.

    This study was conducted in 16 healthy immature dromedary camels weighing 120-150 kg to evaluate and compare the effects of epidural and intramuscular injections of xylazine administered at 0.1 mg/kg and 0.2 mg/kg. Haematological parameters included haemoglobin, packed cell volume, total erythrocyte count and total leukocyte count. Biochemical parameters included alkaline phosphates, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and glucose. Parameters were measured at different intervals before (baseline) and after the administration of drugs. Our study showed that the effect of xylazine on haematological and biochemical parameters is dose-dependant and is also related to the route of administration. The low dose of xylazine administered using both intramuscular and epidural methods showed minimal effects, whereas high doses of the drug, especially when injected intramuscularly, caused greater changes in haematological and biochemical parameters.

    2016-04-01

    Myofascial pain syndrome (MPS) is one of the common musculoskeletal conditions of the shoulder which may develop sensory-motor and autonomic dysfunctions at the various level of the neuromuscular system. The pain and dysfunction caused by MPS were primarily treated with physical therapy and pharmacological agents in order to achieve painfree movements. However, in recent years intramuscular electrical stimulation (IMES) with conventional electrode placement was used by researchers to maximise therapeutic values. But, in this study an inverse electrode placement was used to deliver electrical impulses intramuscularly to achieve neuro-modulation at the various level of the nervous system. Nine patients with MPS were treated with intramuscular electrode stimulation using inversely placed electrodes for a period of three weeks. All nine subjects recovered from their shoulder pain and disability within the few weeks of intervention. So, this inverse electrode placement may be more appropriate for chronic pain management.

    In chickens, the nematode Ascaridia galli is found with prevalences of up to 100% causing economic losses to farmers. No avian nematode vaccines have yet been developed and detailed knowledge about the chicken immune response towards A. galli is therefore of great importance. The objective...... of this study was to evaluate the induction of protective immune responses to A. galli soluble antigen by different immunization routes. Chickens were immunized with a crude extract of A. galli via an oral or intra-muscular route using cholera toxin B subunit as adjuvant and subsequently challenged with A....... galli. Only chickens immunized via the intra-muscular route developed a specific A. galli antibody response. Frequencies of γδ T cells in spleen were higher 7 days after the first immunization in both groups but only significantly so in the intra-muscularly immunized group. In addition, systemic...

    In this study we measured 13C values of the main fatty acids (FA) present in neutral and polar intramuscular lipids of meat samples from 24 lambs, fed with four different diets supplemented with sunflower and linseed oil and the tanniferous shrub Cistus ladanifer L. The objective was to understand if the increase in intramuscular fat observed in lambs fed simultaneously C. ladanifer and oil was explained mostly by incorporation of diet derived FA or by increased de novo FA synthesis. De novo FA synthesis was evaluated by 13C enrichment (‰) of 16:0 in intramuscular lipids compared to bulk diet or compared to dietary 16:0. Oil reduced 13C enrichment of 16:0 in muscle lipid, but had no effect when the diet included C. ladanifer (P value < 0.01). Thus dietary C. ladanifer blocked the inhibitory effects of lipid supplementation on de novo FA synthesis.

    There is an urgent need for a therapy that reverses disability after stroke when initiated in a time frame suitable for the majority of new victims. We show here that intramuscular delivery of neurotrophin-3 (NT3, encoded by NTF3) can induce sensorimotor recovery when treatment is initiated 24 h after stroke. Specifically, in two randomized, blinded preclinical trials, we show improved sensory and locomotor function in adult (6 months) and elderly (18 months) rats treated 24 h following cortical ischaemic stroke with human NT3 delivered using a clinically approved serotype of adeno-associated viral vector (AAV1). Importantly, AAV1-hNT3 was given in a clinically-feasible timeframe using a straightforward, targeted route (injections into disabled forelimb muscles). Magnetic resonance imaging and histology showed that recovery was not due to neuroprotection, as expected given the delayed treatment. Rather, treatment caused corticospinal axons from the less affected hemisphere to sprout in the spinal cord. This treatment is the first gene therapy that reverses disability after stroke when administered intramuscularly in an elderly body. Importantly, phase I and II clinical trials by others show that repeated, peripherally administered high doses of recombinant NT3 are safe and well tolerated in humans with other conditions. This paves the way for NT3 as a therapy for stroke.

    With the continuing development of nanomaterials, the assessment of their potential impact on human health, and especially human reproductive toxicity, is a major issue. The testicular biodistribution of nanoparticles remains poorly studied. This study investigated whether gold-silica nanoparticles could be detected in mouse testes after intramuscular injection, with a particular focus on their ability to cross the blood-testis barrier. To that purpose, well-characterized 70-nm gold core-silica shell nanoparticles were used to ensure sensitive detection using high-resolution techniques. Testes were collected at different time points corresponding to spermatogenesis stages in mice. Transmission electron microscopy and confocal microscopy were used for nanoparticle detection, and nanoparticle quantification was performed by atomic emission spectroscopy. All these techniques showed that no particles were able to reach the testes. Results accorded with the normal histological appearance of testes even at 45 days post sacrifice. High-resolution techniques did not detect 70-nm silica-gold nanoparticles in mouse testes after intramuscular injection. These results are reassuring about the safety of nanoparticles with regard to male human reproduction, especially in the context of nanomedicine.

  15. A successfully treated case of necrotizing fasciitis with complicated sepsis due to intramuscular steroid injection

    Full Text Available Necrotising fasciitis is a devastating soft tissue infection which characterised by rapidly progressing necrosis involving mainly fascia and subcutaneous tissues. A 66-year old male patient with chronic obstructive pulmonary disease admitted to our hospital with fever, pain and swelling in the right thigh and right leg, difficulty in walking, dry mouth and weakness. There was a single dose intramuscular steroid injection story in his anamnesis. Physical examination revealed swelling, hyperemia and pain in the right gluteal region spreading through the right femur and popliteal fossa. He was diagnosed necrotizing fasciitis complicated with sepsis. We administered the supportive therapy and broad-spectrum antibiotic therapy in addition to the surgical debridement, vacuum assisted closure and hyperbaric oxygen therapy. The patient was discharged after six months of the follow-up period in hospital. In conclusion, Health-care personnel should be careful when the intramuscular injections planned for patients at the risk of development of necrotizing fasciitis reason of their chronic illnesses or immunosuppressive conditions. In patients who developed necrotizing fasciitis despite everything, we want to strongly emphasise the advantageous hyperbaric oxygen therapy as an additional therapy to the broad spectrum antibiotherapy and surgical debridement [Cukurova Med J 2016; 41(4.000: 787-791

    DNA vaccines are being developed as a potentially safe and effective immunization platform. However, translation of DNA vaccines into a clinical setting has produced results that have fallen short of those generated in a preclinical setting. Various strategies are being developed to address this lack of potency, including improvements in delivery methods. Electroporation (EP) creates transient increases in cell membrane permeability, thus enhancing DNA uptake and leading to a more robust immune response. Here, we report on the safety and tolerability of delivering sterile saline via intramuscular (IM) or intradermal (ID) injection followed by in vivo electroporation using the CELLECTRA® adaptive constant current device in healthy adults from two open-label studies. Pain, as assessed by VAS, was highest immediately after EP but diminishes by about 50% within 5 min. Mean VAS scores appear to correlate with the amount of energy delivered and depth of needle insertion, especially for intramuscular EP. Mean scores did not exceed 7 out of 10 or 3 out of 10 for IM and ID EP, respectively. The majority of adverse events included mild to moderate injection site reactions that resolved within one day. No deaths or serious adverse events were reported during the course of either study. Overall, injection followed by EP with the CELLECTRA® device was well-tolerated and no significant safety concerns were identified. These studies support the further development of electroporation as a vaccine delivery method to enhance immunogenicity, particularly for diseases in which traditional vaccination approaches are ineffective.

  17. Intramuscular Anabolic Signaling and Endocrine Response Following Resistance Exercise: Implications for Muscle Hypertrophy.

    Maintaining skeletal muscle mass and function is critical for disease prevention, mobility and quality of life, and whole-body metabolism. Resistance exercise is known to be a major regulator for promoting muscle protein synthesis and muscle mass accretion. Manipulation of exercise intensity, volume, and rest elicit specific muscular adaptations that can maximize the magnitude of muscle growth. The stimulus of muscle contraction that occurs during differing intensities of resistance exercise results in varying biochemical responses regulating the rate of protein synthesis, known as mechanotransduction. At the cellular level, skeletal muscle adaptation appears to be the result of the cumulative effects of transient changes in gene expression following acute bouts of exercise. Thus, maximizing the resistance exercise-induced anabolic response produces the greatest potential for hypertrophic adaptation with training. The mechanisms involved in converting mechanical signals into the molecular events that control muscle growth are not completely understood; however, skeletal muscle protein synthesis appears to be regulated by the multi-protein phosphorylation cascade, mTORC1 (mammalian/mechanistic target of rapamycin complex 1). The purpose of this review is to examine the physiological response to resistance exercise, with particular emphasis on the endocrine response and intramuscular anabolic signaling through mTORC1. It appears that resistance exercise protocols that maximize muscle fiber recruitment, time-under-tension, and metabolic stress will contribute to maximizing intramuscular anabolic signaling; however, the resistance exercise parameters for maximizing the anabolic response remain unclear.

    This study was conducted to assess optimal needle length for gluteal intramuscular injections (IM) via simple skinfold thickness (SFT). For this study, 190 healthy adults were recruited and grouped into eight groups according to gender and body mass index (BMI) (kg/m²). The Korean Society for the Study of Obesity criteria defines a BMI under 20 as underweight, 20.1-22.9 as normal, 23-24.9 as overweight and over 25 as obese. For each participant, the SFT of dorsoguteal (DG) and ventrogluteal (VG) sites were measured using a caliper. Subcutaneous tissue thickness was acquired through ultrasonic images. For men in the overweight and obese groups at the DG site, for the obese group at the VG site, and for women in the normal weight, overweight and obese groups at both sites, the mean subcutaneous tissue thickness exceeded 1.84 cm, the minimal length for a 1 inch needle used for IM. At the DG site, optimal intramuscular needle length (OINL) was 1.4 times in women and 1.0 times in men compared to SFT. At the VG site, OINL was 1.3 times in women and 0.9 times in men compared to SFT. The results of this study suggest that SFT is a reliable index to determine optimal needle length with minimal effort prior to IM.

    Data on early biochemical and hematological responses to cobalamin therapy in vitamin B12-deficient patients are scarce. Therefore, we investigated whether cobalamin injections would include prompt biochemical and hematological responses in vitamin B12-deficient patients. Seven female patients (mean age: 69.4 years, range: 61-78) with a mean serum cobalamin level of 104 ± 38 pmol/l mean ± SD and 7 male patients (mean age: 67.0 years, range: 53-78) with a mean serum cobalamin level of 84 ± 40 (±SD) participated in the study. They were administered 1 mg i.m. cyanocobalamin per week for 3 weeks. Blood samples were collected before and 1, 3, 7, 14 and 21 days after cobalamin injection. The concentrations of plasma aminothiols and serum methylmalonic acid (MMA) were measured with high-performance liquid chromatography and gas chromatography/mass spectrometry, respectively, and hematological parameters were determined with a hematological analyzer. Already 1 day after intramuscular Cobalamin injections, the concentrations of serum vitamin B12 and plasma total cysteine were significantly increased while the concentrations of serum folate, plasma total homocysteine and serum MMA were decreased. Mean cell volume was also significantly decreased first after 14 days of therapy. Intramuscular cobalamin administration causes swift and significant changes in plasma aminothiols, whereas the first change in hematological parameters was detected only after 14 days.

    Plasma concentrations and pharmacokinetics of dexmedetomidine and buprenorphine after oral transmucosal (OTM) and intramuscular (i.m.) administration of their combination in healthy adult cats were compared. According to a crossover protocol (1-month washout), a combination of dexmedetomidine (40 μg/kg) and buprenorphine (20 μg/kg) was given OTM (buccal cavity) or i.m. (quadriceps muscle) in six female neutered cats. Plasma samples were collected through a jugular catheter during a 24-h period. Plasma dexmedetomidine and buprenorphine concentrations were determined by liquid chromatography-tandem mass spectrometry. Plasma concentration-time data were fitted to compartmental models. For dexmedetomidine and buprenorphine, the area under the plasma concentration-time curve (AUC) and the maximum plasma concentrations (Cmax ) were significantly lower following OTM than following i.m. administration. For buprenorphine, time to reach Cmax was also significantly longer after OTM administration than after i.m. injection. Data suggested that dexmedetomidine (40 μg/kg) combined with buprenorphine (20 μg/kg) is not as well absorbed from the buccal mucosa site as from the intramuscular injection site.

    An innovative fiber optic pressure microsensor has been developed that is based upon on Luna Innovations' patented extrinsic Fabry-Perot interferometric (EFPI) technique. The basic physics governing the operation of these sensors makes them relatively tolerant or immune to the effects of high-temperature, high-EMI, and highly-corrosive environments. Luna's pressure microsensor is extremely small, with an outer diameter of only 200 microns and a length of less than 1mm. The pressure microsensor has a high sensitivity that allows for sub-mmHg resolution over a dynamic range of 0-300 mmHg. The combination of these features makes this pressure microsensor ideal for medical applications where small size, high sensitivity and accuracy, EMI immunity, biocompatibility, and survivability (e.g. sterilizable - steam, ethylene oxide) are important. One example medical application of the pressure microsensor has been to adapt the microsensor for measurement of intramuscular pressure in vivo during active and passive muscle activation. Clinically it is difficult to study the in vivo mechanical properties of individual skeletal muscles for a variety of reasons. Initial experiments have demonstrated a correlation between intramuscular pressure and force. Such measurements can be a useful diagnostic tool for clinicians assessing muscular deficits in patients.

    Aluminum-adjuvanted vaccines are administered through an intramuscular injection (IM) in the US and EU, however, a subcutaneous injection (SC) has been recommended in Japan because of serious muscle contracture previously reported following multiple IMs of antibiotics. Newly introduced adjuvanted vaccines, such as the human papillomavirus (HPV) vaccines, have been recommended through IM. In the present study, currently available vaccines were evaluated through IM in mice. Aluminum-adjuvanted vaccines induced inflammatory nodules at the injection site, which expanded into the intra-muscular space without any muscle degeneration or necrosis, whereas non-adjuvanted vaccines did not. These nodules consisted of polymorph nuclear neutrophils with some eosinophils within the initial 48h, then monocytes/macrophages 1 month later. Inflammatory nodules were observed 6 months after IM, had decreased in size, and were absorbed 12 months after IM, which was earlier than that after SC. Cytokine production was examined in the injected muscular tissues and AS04 adjuvanted HPV induced higher IL-1β, IL-6, KC, MIP-1, and G-CSF levels in muscle tissues than any other vaccine, but similar serum cytokine profiles were observed to those induced by the other vaccines. Currently available vaccines did not induce muscular degeneration or fibrotic scar as observed with muscle contracture caused by multiple IMs of antibiotics in the past.

    Meloxicam is an anti-inflammatory and analgesic drug used to treat many pathological conditions in turtles. With the aim to fill the lack of data about its pharmacokinetic in this species, eighteen turtles (Trachemys scripta scripta) were divided in three groups and treated with a single dose of meloxicam (0.2 mg/kg) by intramuscular, intracoelomic and oral route, respectively. At scheduled time points, blood samples were collected and meloxicam concentrations were determined by HPLC. Pharmacokinetic parameters were calculated from the obtained concentration-time curves. After intramuscular treatment, a plasma peak of meloxicam equal to 1590.03 ± 1845.32 ng/mL (mean ± SD) and a Tmax of 1.17 ± 0.45 h were reached, indicating a quick absorption of the drug. The intracoelomic administration brought to the largest AUC (12621.04 ± 6203.79 h*ng/mL) and to a Cmax and a Tmax equal to 1154.52 ± 662.78 ng/mL and 2.82 ± 1.39 h, respectively. Following oral treatment, the plasma concentrations of meloxicam were very low indicating a scarce absorption. Further studies are warranted to determine the effective plasma concentration of meloxicam in turtles and, consequently, the dosage regimen.

    The feasibility of percutaneous intramuscular functional electrical stimulation (P-FES) in children with cerebral palsy (CP) for immediate improvement of ankle kinematics during gait has not previously been reported. Eight children with CP (six with diplegia, two with hemiplegia; mean age 9 years 1 month [SD 1 y 4 mo; range 7 y 11 mo to 11 y 10 mo]) had percutaneous intramuscular electrodes implanted into the gastrocnemius (GA) and tibialis anterior (TA) muscles of their involved limbs. Stimulation was provided during appropriate phases of the gait cycle in three conditions (GA only, TA only, and GA/TA). immediately after a week of practice for each stimulation condition, a gait analysis was performed with and without stimulation. A significant improvement in peak dorsiflexion in swing for the more affected extremity and dorsiflexion at initial contact for the less affected extremity were found in the GA/TA condition. Clinically meaningful trends were evident for improvements in dorsiflexion kinematics for the more and less affected extremities in the TA only and GA/TA conditions. The results suggest that P-FES might immediately improve ankle kinematics in children with CP.

    Currently, the definitive diagnosis of chronic compartment syndrome is based on invasive measurements of intracompartmental pressure. We measured the intramuscular pressure and the relative oxygenation in the anterior compartment of the leg in eighteen patients who were suspected of having chronic compartment syndrome as well as in ten control subjects before, during, and after exercise. Chronic compartment syndrome was considered to be present if the intramuscular pressure was at least fifteen millimeters of mercury (2.00 kilopascals) before exercise, at least thirty millimeters of mercury (4.00 kilopascals) one minute after exercise, or at least twenty millimeters of mercury (2.67 kilopascals) five minutes after exercise. Changes in relative oxygenation were measured with use of the non-invasive method of near-infrared spectroscopy. In all patients and subjects, there was rapid relative deoxygenation after the initiation of exercise, the level of oxygenation remained relatively stable during continued exercise, and there was reoxygenation to a level that exceeded the pre-exercise resting level after the cessation of exercise. During exercise, maximum relative deoxygenation in the patients who had chronic compartment syndrome (mean relative deoxygenation [and standard error], -290 +/- 39 millivolts) was significantly greater than that in the patients who did not have chronic compartment syndrome (-190 +/- 10 millivolts) and that in the control subjects (-179 +/- 14 millivolts) (p compartment syndrome (184 +/- 54 seconds) than for the patients who did not have chronic compartment syndrome (39 +/- 19 seconds) and the control subjects (33 +/- 10 seconds) (p < 0.05 for both comparisons).

    Full Text Available Introduction. Intramuscular lipoma is a very rare form of lipoma, known to be categorized as an infiltrating lipoma due to its tendencies to infiltrate the muscle or the synovium. Contrary to other subcutaneous lipomas, even after surgical removal, the rate of local recurrence ranges at a high rate from 50∼80% and differential diagnosis with liposarcoma is very difficult. Patients and Methods. A retrospective chart review was conducted for a total of 27 patients. Before performing a surgery based on the types of mass, a radiologic imaging study was performed. An intraoperative frozen biopsy was performed on every patient and the results were compared. The progress was monitored every 3 to 6 months for recurrence or struggles with rehabilitation. Results. There were 13 male and 14 female patients with an average age of 54.6. The average tumor size was 8.2 cm (1.1 cm∼31.6 cm. Excision was performed using a wide excision. All 27 individuals were initially diagnosed as intramuscular lipoma; however, 1 of the patients was rediagnosed as liposarcoma in the final checkup. The patients had an average of 3 years and 1 month of follow-up and did not suffer recurrences. Conclusion. Thus, it is essential that a frozen biopsy is performed during the surgery in order to identify its malignancy. And a wide excision like malignant tumor operation is a principle of treatment.

    Excessive abdominal fat content (AFC) has negative impacts on feed efficiency and carcass quality. Unlike AFC, intramuscular fat content (IMFC) could be a favourable trait, which has a positive impact on meat quality. To meet consumers' needs, a long-term goal of broiler breeders is to decrease AFC and improve the IMFC simultaneously. The current study was designed to investigate the relationship between AFC and IMFC and to compare IMFC, including the pectoral major muscle fat content (PIMFC) and intramuscular fat content of leg muscle (LIMFC), between two broiler lines divergently selected for abdominal fat percentage over 17 generations. The results showed that there was a significant difference in PIMFC and LIMFC between the two lines in all five generation populations used. The birds in the lean line had significantly lower AFC but higher PIMFC and LIMFC than the birds in the fat line. We also detected differences in the liver fat content (LFC) between the two lines and the results showed that birds in the fat line had significant higher LFC than birds in the lean line. Our results indicated that a desirable broiler line with higher IMFC but lower AFC could be obtained by genetic selection.

    Given the substantial rise in obesity, depot-specific fat accumulation and its associated diseases like diabetes, it is important to understand the molecular basis of depot-specific adipocyte differentiation. Many studies have successfully exploited the adipocyte differentiation, but most of them were not related to depot-specificity, particularly using freshly isolated primary preadipocytes. Using 2-dimensional polyacrylamide gel electrophoresis coupled with sequencing mass spectrometry, we searched and compared the proteins differentially expressed in undifferentiated and differentiated preadipocytes from bovine omental, subcutaneous and intramuscular adipose depots. Our proteome mapping strategy to identify differentially expressed intracellular proteins during adipogenic conversion revealed 65 different proteins that were found to be common for the three depots. Further, we validated the differential expression for a subset of proteins by immunoblotting analyses. The results demonstrated that many structural proteins were down-regulated during differentiation of preadipocytes from all the depots. Most up-regulated proteins like Ubiquinol-cytochrome-c reductase complex core protein I (UQCRC1), ATP synthase D chain, Superoxide dismutase (SOD), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), Sulfotransferase 1A1 (SULT1A1), Carnitine O-palmitoyltransferase 2 (CPT2) and Heat-shock protein beta 1 (HSPB1) across the three depots were found to be associated with lipid metabolism and metabolic activity. Further, all the up-regulated proteins were found to have higher protein expression in omental than subcutaneous or intramuscular depots.

    This year, the 48-hour film project (48hfp) returns to Geneva after a one-year hiatus. Organized by Neal Hartman and the CERN film-making club, Open Your Eyes Films, the 48hfp challenges teams of film-makers to write, shoot, soundtrack and edit a 4 to 7 minute film in 48 hours from 4 to 6 November.   At the start of the festival, contestants picked their film genre from a hat. The films will be screened on 8 and 9 November, with the awards presentation on the 9th. The winner will receive a trip to the US to compete in the international version of the competition. “There are so many short films being made now," says Hartman, “I think, however, that the 48hfp allows a critical creative mass to form. The result is that these 20 teams make 20 better films than if each participant were making their own." Each team draws a genre from a hat and is given a character, a prop and a line of dialogue that must appear in their film. The genres run the gamut from &am...

    Vitamin K1 is frequently used in the treatment and prevention of hypoprothrombinemia and hemorrhagic disease of the newborn. It also serves as an antidote to anticoagulants. Erythematous, indurated, pruritic plaques uncommonly occur in adults after intramuscular injection with vitamin K1. We present a case of a localized cutaneous reaction to intramuscular vitamin K1 in a peripartum patient with acute fatty liver of pregnancy. The history and clinical presentation of our case is presented with a discussion of the pathogenesis pathogenesis of vitamin K1 and available treatment for this condition.

    Nicolau syndrome, also known as embolia cutis medicamentosa or livedo-like dermatitis, is a sudden tissue necrosis, a rare complication of intramuscular injection of some drugs. We report a case of a 6-month-old girl who received intramuscularly the third dose of hexavalent vaccine (DTaP- HVB-IPV/HIb), and immediately presented a livedoid lesion around the injection site, progressing to necrosis. We reinforce the importance of early diagnosis to perform a suitable treatment and clinical follow-up to avoid ischemic secondary complications.

    Full Text Available The use of butafosfan in combination with cobalamin modulates many cellular metabolic functions in several species. Its use enhances productive and reproductive performance and reduces stress responses in animals. Despite all these attributes, so far there have been no controlled studies to evaluate the effects of butafosfan and cobalamin on the quality of stallion semen. The purpose of this study was to evaluate the action of butafosfan in combination with cobalamin on the quality of fresh and cooled stallion semen. Four healthy stallions were kept in the same place and under the same management conditions during the entire experiment. Stallions were randomly assigned to two treatment groups in a 2x2 crossover design. Group A stallions were treated with an intramuscular injection of butafosfan twice a week for 80 days, while group B did not receive any treatment. After that, both groups were not treated for another 80 days allowing a washout period for the treated group. Then, the groups were reversed, and group B was treated with butafosfan and group A acted as the control for another 80 days. Semen was collected twice a week, diluted in skim milk and evaluated for total sperm count, total and progressive sperm motility, membrane integrity (CFDA/PI staining and membrane functionality (HOS test at 0 and 24 hours after preservation at 5ºC. Data were analyzed by comparing the values obtained from the treated stallions between the 60th and 84th days of treatment and the values obtained from the same stallion during the control period. The ejaculates of the washout period and between days 1 and 63 of treatment were not considered. A total of 85 ejaculates were analyzed by one-way ANOVA. Means were compared by the Tukey test at the 5% level of significance. No significant differences were observed in fresh and cooled semen regarding the total sperm count, total motility, progressive motility, membrane integrity and membrane functionality in the

    2010-12-01

    Full Text Available Maintenance of the training aircraft causes downtime of operations and thereby reduces the operational availability, which is crucial for flight planning in a training organisation. Manual daily planning within the fleet delivers suboptimal results and often causes discontinued flight of several aircraft that have to be maintained at the same time. Optimal maintenance schedule of training aircraft can be obtained by a sliding scale method. This paper presents a mathematical model of the sliding scale formulated by a mixed integer linear problem. Allocation of flight hours is optimised by using AMPL programming language, assuring that a sufficient number of aircraft are always available for training. The model can be used by a flight dispatch department in a training organisation as a basis for optimised planning and reduction of maintenance downtime.

    Full Text Available Anatomical studies of leaf and stem of twelve clones of Camellia were investigated. Cross sections of the stem of all the clones exhibited a typical pattern of arrangement of tissues characteristics of woody plants. Two types of idioblastic sclereids were found in the medullary parenchyma of the taxa studied. While astrosclereids werepresent in 10 of the twelve clones, the vesciculose sclereids were found only in the four clones belonging to C. sinensis. Leaves of the clones show variations in the number of palisade layers. Astro sclereids, brachy sclereids, and dendritic forms were observed in the leaves, their distribution varying in the different clones. A few other micromorphological features are also recorded. Our study forms a basis for answering uncertainties in taxonomic revision in the genus Camellia.

    Premarital sex increases the risk of unintended pregnancy and sexually transmitted infections including HIV if unprotected and contraception is not used. Thus, the objective of this study was to assess premarital sex in the last twelve months and its predictors among regular undergraduate students of Wollega University. A cross-sectional survey using pretested, structured questionnaire was conducted on a total of 704 regular undergraduate students of Wollega University from February to March, 2014. We used multistage sampling technique to recruit study participants. Binary and multivariable logistic regressions were performed using SPSS version 20 to assess predictors of premarital sex. Statistical significance was determined through a 95% confidence level. Wollega University youths who had premarital sex in the last twelve months were 28.4%; 55.5% of them did not use condom during last sex while 31.3% engaged in multiple sex. Being male [Adjusted Odds Ratio (AOR)(95% Confidence Interval(CI))=2.7(1.58-4.75)], age 20-24 years [AOR(95%CI)=2.8(1.13-7.20)], training on how to use condom [AOR(95%CI)=1.7(1.17-2.46)], being tested for HIV [AOR(95%CI)=2.3(1.48-3.53)], using social media frequently [AOR(95%CI)=1.8(1.14-2.88)], having comprehensive knowledge of HIV [AOR(95% CI)=1.5(1.01-2.10)], alcohol use [AOR (95%CI)=2.2(1.31-3.56)] were associated with increased odds of premarital sex in the last twelve months. Nearly one-third of regular undergraduate students of the university were engaged in premarital sex in the last twelve months. Being male, using social media frequently and alcohol use were associated with increased odds of premarital sex in the stated period. Thus, higher institutions have to deliver abstinence messages alongside information about self-protection.

    The genomics era has led to an explosion in the study of gene expression in production animals. Intramuscular fat (IMF) content (both high and low) and composition are major quality attributes of meat, and more than 90 transcriptomic studies of IMF deposition have been undertaken in the ruminants and pigs since 2001, with the majority since 2008. The studies have implicated many genes involved in the control of adipogenesis, lipogenesis, and deposition of IMF, but there is relatively little consistency between the different studies. However, the genes encoding the synthesis enzymes acetyl-CoA carboxylase α, fatty acid synthase, and stearoyl-CoA desaturase; the fatty acid binding protein 4; the potential signaling protein thyroid hormone responsive; and the regulators C/EBPα, PPARγ, and sterol regulatory element binding transcription factor 1 are supported by 5 or more of the 90 studies. By combining the results of all the studies, complete pathways for long-chain fatty acid (LCFA) and triacylglyceride (TAG) synthesis are identified, as are a number of genes encoding proteins probably associated with the storage of TAG and genes encoding a number of known and potential adipokines. In contrast, support for the association of lipolytic pathways with IMF percentage is less strong. Differences in experimental design-in particular, the age of the animals, the rate of IMF deposition at sampling, the past nutritional history of the animals used, and the complexities of using a tissue with mixed cell types-have contributed to the differences in results and interpretation. Biomarkers predictive of future IMF percentage, facilitating reaching optimal IMF content at slaughter, may have industry utility, but to be useful in animal biopsy and postslaughter samples, where multiple cell types are present, genes must be carefully chosen to ensure that they are informative about the expected processes. Despite these problems, candidate biomarkers for estimation of de novo

    Full Text Available Abstract Background New advances in high-throughput technologies have allowed for the massive analysis of genomic data, providing new opportunities for the characterization of the transcriptome architectures. Recent studies in pigs have employed RNA-Seq to explore the transcriptome of different tissues in a reduced number of animals. The main goal of this study was the identification of differentially-expressed genes in the liver of Iberian x Landrace crossbred pigs showing extreme phenotypes for intramuscular fatty acid composition using RNA-Seq. Results The liver transcriptomes of two female groups (H and L with phenotypically extreme intramuscular fatty acid composition were sequenced using RNA-Seq. A total of 146 and 180 unannotated protein-coding genes were identified in intergenic regions for the L and H groups, respectively. In addition, a range of 5.8 to 7.3% of repetitive elements was found, with SINEs being the most abundant elements. The expression in liver of 186 (L and 270 (H lncRNAs was also detected. The higher reproducibility of the RNA-Seq data was validated by RT-qPCR and porcine expression microarrays, therefore showing a strong correlation between RT-qPCR and RNA-Seq data (ranking from 0.79 to 0.96, as well as between microarrays and RNA-Seq (r=0.72. A differential expression analysis between H and L animals identified 55 genes differentially-expressed between groups. Pathways analysis revealed that these genes belong to biological functions, canonical pathways and three gene networks related to lipid and fatty acid metabolism. In concordance with the phenotypic classification, the pathways analysis inferred that linolenic and arachidonic acids metabolism was altered between extreme individuals. In addition, a connection was observed among the top three networks, hence suggesting that these genes are interconnected and play an important role in lipid and fatty acid metabolism. Conclusions In the present study RNA-Seq was used

    The present study aimed to evaluate the influence of salt and intramuscular fat (IMF) content on the sensory characteristics of two different types of dry-cured hams (Iberian and Serrano) using the time-intensity (TI) method. All studied TI parameters of flavour attributes (overall flavour, saltiness, cured and rancid flavours) were significantly (p < 0.05) affected by variations in the salt and/or IMF content. However, regarding texture attributes only the maximum intensity (Imax) of hardness was significantly (p < 0.05) affected by the salt content of hams. Compared to Iberian dry-cured hams, the dynamic perception of the flavour and texture of Serrano dry-cured hams was less influenced by variations in salt and/or IMF content. The dynamic sensory techniques may be helpful to guarantee the quality of dry-cured products subjected to strategies of salt and fat reduction.

    Thirty-one thighs were obtained from Iberian pigs fattened with acorns and were processed during 22 months in the traditional dry-curing process. Lipolysis affecting intramuscular fat during the processing of Iberian dry-cured ham has been analyzed by studying the changes of glycerides, phospholipids and free fatty acids in lipids from Biceps femoris muscle. Little change affected the fatty acid composition of glycerides during processing. A double-phased increase in the acidity values and a decrease in the quantity of fatty acids of phospholipids during the processing were observed. There seems to be a relationship between the extension of the lipolysis taking place during the maturing and the processing conditions and raw material used.

    Full Text Available Cylindrical elastomers were prepared through the UV-initiated crosslinking of terminally acrylated, 8,000 Da star-poly(trimethylene carbonate-co-ε-caprolactone and star-poly(trimethylene carbonate-co-D,L-lactide. These elastomers were implanted intramuscularly into the hind legs of male Wistar rats to determine the influence of the comonomer on the weight loss, tissue response, and change in mechanical properties of the elastomer. The elastomers exhibited only a mild inflammatory response that subsided after the first week; the response was greater for the stiffer D,L-lactide-containing elastomers. The elastomers exhibited weight loss and sol content changes consistent with a bulk degradation mechanism. The D,L-lactide-containing elastomers displayed a nearly zeroorder change in Young’s modulus and stress at break over the 30 week degradation time, while the ε-caprolactone-containing elastomers exhibited little change in modulus or stress at break.

    A simple, rapid and specific ion-pair liquid chromatographic method for the routine determination of the marker residue of oxytetracycline in sheep milk, at levels as low as 20 microg/kg, has been developed. Milk samples were acidified and extracted with acetonitrile. The extracts were purified by treatment with ammonium sulphate and concentrated into diluted phosphoric acid. Separation was carried out isocratically on a Nucleosil C(18) column using a mobile phase that contained both positively and negatively charged pairing ions. The in-house validated method gave overall recoveries and overall relative standard deviations better than 86% and 4.6%, respectively. The method was successfully applied to study the depletion of oxytetracycline in sheep milk and to estimate the withdrawal period after intramuscular administration of a commercial oxytetracycline formulation.

    A nearly 5 year-old boy presented with proximal muscle weakness, reduced muscle bulk, a positive Gower sign and Trendelenburg gait. He was known to have cholestatic liver disease. Investigations revealed markedly low serum total calcium, elevated alkaline phosphatase, very low serum 25-hydroxyvitamin D, and radiographs consistent with active rickets despite the ongoing administration of a water-soluble preparation of vitamin D. Only i.v. calcitriol acutely corrected the hypocalcemia, despite trying several oral preparations, suggesting that malabsorption secondary to chronic liver disease was the cause of his rickets. Intramuscular calciferol quickly corrected his muscle weakness and X-ray findings. Myopathy secondary to vitamin D deficiency is an uncommon diagnosis in children. Intermittent calciferol is an inexpensive and practical treatment for vitamin D deficiency, especially if associated with malabsorption.

    A pharmacokinetic study of a commercial florfenicol-tylosin (2:1) combination product was conducted in six beagle dogs after intravenous (IV) and intramuscular (IM) administration at doses of 10 mg/kg (florfenicol) and 5 mg/kg (tylosin). Serum drug concentrations were determined by a validated high performance liquid chromatography (HPLC) using UV detection. A rapid and nearly complete absorption of both drugs with a mean IM bioavailability of 103.9% (florfenicol) and 92.6% (tylosin), prolonged elimination half-life, and high tissue penetration with steady state volume of distribution of 2.63 l/kg (florfenicol) and 1.98 l/kg (tylosin) were observed. Additional studies, including pharmacodynamic and toxicological evaluation are required before recommendations can be made regarding the clinical application of the product in dogs.

    Full Text Available We report a case of a 22-year-old female student nurse who presented to hospital with an acute neuro-ophthalmological syndrome characterized by papilledema, ataxia, ophthalmoplegia and headache after a single first time use of 150 mg medroxyprogesterone intramuscular injection. Clinical, laboratory, radiological and ophthalmological investigations were in keeping with the diagnosis of idiopathic intracranial hypertension but lumbar puncture did not show a raised cerebrospinal fluid pressure suggesting a forme fruste of this entity. Her neuro-ophthalmological clinical features responded well to acetazolamide and diagnostic/ therapeutic lumbar puncture. Full recovery was achieved three months after medroxyprogesterone usage. Health care providers must be aware of this adverse drug reaction.

    For the consumer, tenderness, juiciness and flavour are often described as the most important factors for meat eating quality, all of which have a close association with intramuscular fat (IMF). X-ray computed tomography (CT) can measure fat, muscle and bone volumes and weights, in vivo in sheep and CT predictions of carcass composition have been used in UK sheep breeding programmes over the last few decades. This study aimed to determine the most accurate combination of CT variables to predict IMF percentage of M. longissimus lumborum in Texel lambs. As expected, predicted carcass fat alone accounted for a moderate amount of the variation (R(2)=0.51) in IMF. Prediction accuracies were significantly improved (Adj R(2)>0.65) using information on fat and muscle densities measured from three CT reference scans, showing that CT can provide an accurate prediction of IMF in the loin of purebred Texel sheep.

    Full Text Available The aim of the study was to compare the slaughter value and meat quality of the first farrowing gilts with normal fattening gilts. The study was carried out on 30 primiparous gilts (A and 39 fattening gilts (B. Age of A gilts at slaughter was 371.03 days and that of B gilts was two times lower and attained 179.64 days. However carcass fatness of the younger B gilts was higher than of primiparous gilts (P < 0.05 and carcass lean content was high in both gilt groups. Meat characteristics were determined in longissimus lumborum muscle. Some differences between the compared gilt groups were stated in muscle colour, WHC, protein and intramuscular fat content. Higher IMF content was found in primiparous gilts (1.88 ± 0.50 versus 1.19 ± 0.39%; P< 0.01.

    The method of the proton induced x-ray emission ( PIXE ) was used for the investigation of ion exchange processes on the surface of intramuscularly implanted Bioglass-Ceramics. This method allows a simultaneous analysis free from destruction in concentrations ranges of ppm for several elements. The measurements were carried out with different proton energy, in that manner a relative quantity analysis was possible in different layers. A durable two-layered surface already originates in a short time after the implantation on the implant interface. This one consists of a layer rich in calcium and phosphorus as well as a second zone rich in silicon. The meaning of this two-layered surface for the bio-activity and the bio-stability of the material is discussed.

    Intramuscular fine-wire electrodes monitored the electromyographic activity of quadratus lumborum in four young adults. A wide variety of tasks were performed including flexion tasks, lateral bending, twisting, extension, and lifting tasks. Heavy lifts of barbell weights up to 70 kg activated the quadratus lumborum 74% of their maximum on average while surface recording of erector spinae (L(3)) were only 62% of their maximum activation. The quadratus lumborum was more active (54%) than other muscles during isometric side support postures where the body is held horizontally almost parallel to the floor as the subjects supported themselves on one elbow on the floor together with both feet. Furthermore, it increased activation in response to increasing compression in static upright standing postures. RELEVANCE:--Electromyographic evidence, together with architectural features make the quadratus lumborum a better stabilizer of the spine than psoas. Use of horizontal 'side support' exercise to train this muscle would appear to be a wise choice.

    Full Text Available Background and aim: The third stage of labour is one of the most troublesome stages of child delivery. The basic principle of the third stage management is administrating prophylactic uterotonics. However, the time of its administration varies in different hospitals. This study aimed to determine the effect of intramuscular oxytocin injection after emergence of the fetal anterior shoulder or placental expulsion on bleeding in the third stage of labour. Methodology: This clinical trial was conducted on 100 pregnant women with gestational age of 38-42 weeks, and singleton pregnancies. Subjects were selected using convenience sampling and were then randomly assigned to intervention (injection of 10 IU intramuscular oxytocin after emergence of the fetal anterior shoulder and control (injection of 10 IU intramuscular oxytocin after placental expulsion groups. Blood was collected in containers and weighed with a weighing scale.  A checklist was used to record labor and delivery related data. Data were analyzed by SPSS version 11.5, using Chi-square and t-test. Findings: The mean amount of bleeding during the third stage of labour was 183.4 ± 145.8 and 202.2 ±208.8 ml in intervention and control group, respectively. No significant difference was found between two groups in terms of maternal bleeding. Conclusion: Injection of intramuscular oxytocin either after emergence of the fetal anterior shoulder or placental expulsion does not affect the amount of maternal bleeding during the third stage of labour.

    Current cyanide antidotes are administered by IV infusion, which is suboptimal for mass casualties. Therefore, in a cyanide disaster, intramuscular (IM) injectable antidotes would be more appropriate. We report the discovery of the highly water-soluble sulfanegen triethanolamine as a promising lead for development as an IM injectable cyanide antidote.

    Intramuscular fat (IMF) % contributes positively to the juiciness and flavour of lamb and is therefore a useful indicator of eating quality. A rapid, non-destructive method of IMF determination like computed tomography (CT) would enable pre-sorting of carcasses based on IMF% and potential eating quality. Given the loin muscle (longissimus lumborum) is easy to sample, a single measurement at this site would be useful, providing is correlates well to other muscles. To determine the ability of CT to predict IMF%, this study used 400 animals and examined 5 muscles from three sections of the carcass: from the fore-section the m. supraspinatus and m. infraspinatus, from the saddle-section the m. longissimus lumborum and from the hind-section the m. semimembranosus and m. semitendinosus. The average CT pixel density of muscle was negatively associated with IMF% and can be used to predict IMF% although precision in this study was poor. The ability of CT to predict IMF% was greatest in the m. longissimus lumborum (slope -0.07) and smallest in the m. infraspinatus (slope -0.02). The correlation coefficients of IMF% between the five muscles were variable, with the highest correlation coefficients evident between muscles of the fore section (0.67 between the m. supraspinatus and the m. infraspinatus) and the weakest correlations were between the muscle of the fore and hind section. The correlation between the m. longissimus lumborum to the other muscles was fairly consistent with values ranging between 0.34 and 0.40 (partial correlation coefficient). The correlation between the proportion of carcass fat and the IMF% of the five muscles varied and was greatest in the m. longissimus lumborum (0.41).

  1. Intramuscular Immunisation with Chlamydial Proteins Induces Chlamydia trachomatis Specific Ocular Antibodies.

    Directory of Open Access Journals (Sweden)

    Alexander Badamchi-Zadeh

    Full Text Available Ocular infection with Chlamydia trachomatis can cause trachoma, which is the leading cause of blindness due to infection worldwide. Despite the large-scale implementation of trachoma control programmes in the majority of countries where trachoma is endemic, there remains a need for a vaccine. Since C. trachomatis infects the conjunctival epithelium and stimulates an immune response in the associated lymphoid tissue, vaccine regimens that enhance local antibody responses could be advantageous. In experimental infections of non-human primates (NHPs, antibody specificity to C. trachomatis antigens was found to change over the course of ocular infection. The appearance of major outer membrane protein (MOMP specific antibodies correlated with a reduction in ocular chlamydial burden, while subsequent generation of antibodies specific for PmpD and Pgp3 correlated with C. trachomatis eradication.We used a range of heterologous prime-boost vaccinations with DNA, Adenovirus, modified vaccinia Ankara (MVA and protein vaccines based on the major outer membrane protein (MOMP as an antigen, and investigated the effect of vaccine route, antigen and regimen on the induction of anti-chlamydial antibodies detectable in the ocular lavage fluid of mice.Three intramuscular vaccinations with recombinant protein adjuvanted with MF59 induced significantly greater levels of anti-MOMP ocular antibodies than the other regimens tested. Intranasal delivery of vaccines induced less IgG antibody in the eye than intramuscular delivery. The inclusion of the antigens PmpD and Pgp3, singly or in combination, induced ocular antigen-specific IgG antibodies, although the anti-PmpD antibody response was consistently lower and attenuated by combination with other antigens.If translatable to NHPs and/or humans, this investigation of the murine C. trachomatis specific ocular antibody response following vaccination provides a potential mouse model for the rapid and high throughput

    Full Text Available The Pharmacokinetic aspects of flunixin (FL administered alone and in combination with enrofloxacin (EN, were studied in clinically healthy calves. The experiments were performed on two groups: FL alone {2.2 mg/kg,intramuscular (IM}, and combination of FL (2.2 mg/kg, IM and EN {2.5 mg/kg, IM}. Plasma concentrations of FL were determined using High Performance Liquid Chromatography (HPLC method. Moreover, the effects of FL alone or in combination on liver and kidney functions were also assessed. Flunixin was rapidly absorbed intramuscularly with a half-life of absorption (t of 0.094 h and the peak plasma concentration (C was 1.27 g/mL was attained after 1/2ab max 0.49 h (T . Enrofloxacin significantly altered the pharmacokinetics of FL by delaying its absorption and accelerate its max elimination from body. Significant increases (32% in the area under the curve (AUC and (37% in the elimination rate constant (K from the central compartment and a significant decrease (27% in the elimination half-life (t of FL el 1/2el were found following coadministration with EN, compared with administration of FL alone. The maximum plasma drug concentration (C showed significant increase (28% following the coadministration of EN with FL as max compared to that following the administration of FL alone. It was concluded that the combination of FL and EN negatively altered the kinetics of FL and exaggerated the adverse effect on hepato-renal function in calves consequently; the concomitant use of FL and EN should be avoided in calves.

    Mitochondrial free radical formation has been implicated as a potential mechanism underlying degenerative senescence, although human data are lacking. Therefore, the present study was designed to examine if resting and exercise-induced intramuscular free radical-mediated lipid peroxidation is indeed increased across the spectrum of sedentary aging. Biopsies were obtained from the vastus lateralis in six young (26 + or - 6 yr) and six aged (71 + or - 6 yr) sedentary males at rest and after maximal knee extensor exercise. Aged tissue exhibited greater (P < 0.05 vs. the young group) electron paramagnetic resonance signal intensity of the mitochondrial ubisemiquinone radical both at rest (+138 + or - 62%) and during exercise (+143 + or - 40%), and this was further complemented by a greater increase in alpha-phenyl-tert-butylnitrone adducts identified as a combination of lipid-derived alkoxyl-alkyl radicals (+295 + or - 96% and +298 + or - 120%). Lipid hydroperoxides were also elevated at rest (0.190 + or - 0.169 vs. 0.148 + or - 0.071 nmol/mg total protein) and during exercise (0.567 + or - 0.259 vs. 0.320 + or - 0.263 nmol/mg total protein) despite a more marked depletion of ascorbate and uptake of alpha/beta-carotene, retinol, and lycopene (P < 0.05 vs. the young group). The impact of senescence was especially apparent when oxidative stress biomarkers were expressed relative to the age-related decline in mitochondrial volume density and absolute power output at maximal exercise. In conclusion, these findings confirm that intramuscular free radical-mediated lipid peroxidation is elevated at rest and during acute exercise in aged humans.

    The potential for postmortem redistribution of olanzapine was investigated in beagle dogs. Olanzapine pamoate monohydrate was administered once every 14 days by intramuscular injection for 3 months to fed male dogs (n=15) at a dose of 20 mg/kg olanzapine (equivalent to 46 mg/kg olanzapine pamoate monohydrate). Blood samples were collected after the fifth (Day 57) and sixth (Day 71) doses to determine olanzapine and N-oxide olanzapine concentrations. On Day 71 at 72 h postdose, dogs were euthanized and placed on their backs without additional manipulation and held for postmortem blood, urine, and tissue collection at room temperature for up to 168 h postdose (96 h after euthanasia). Concentrations of olanzapine and N-oxide olanzapine were determined by liquid chromatography-mass spectroscopy/mass spectroscopy (LC-MS/MS). Postmortem olanzapine concentrations in blood increased up to seven-fold compared to the last quantified antemortem blood concentration. Olanzapine concentrations in vein tissue samples (surrogates for peripheral blood) also increased, whereas other tissue concentrations, such as myocardium, lung, liver, and kidney decreased over the postmortem period. An increase in blood concentration of olanzapine after death was observed in all but one animal, suggesting that postmortem redistribution may occur in dogs following biweekly intramuscular administration of olanzapine pamoate monohydrate. The rise in olanzapine concentrations in blood after death in this study may potentially be attributed to diffusion from multiple tissues to blood and, to a lesser extent, reduction of the N-oxide olanzapine metabolite back to olanzapine. However, the generalizability of these results to humans cannot be confirmed by the present study.

    Leukemia is a group of malignant diseases involving peripheral blood and bone marrow. Extramedullary tumor manifestation in leukemia can also occur. They more often involve lymph nodes, skin, and bones. Intramuscular leukemic relapse (ILR) is very unusual. The aim of this analysis was to summarize the reported data regarding clinical signs and radiological features of ILR. The PubMed database was searched for publications related to ILR. After an analysis of all identified articles, 20 publications matched the inclusion criteria. The authors of the 20 publications were contacted and provided imaging of their cases for review. The following were recorded: age, gender, primary diagnosis, clinical signs, pattern, localization and size of the intramuscular leukemic relapse. Images of 16 patients were provided [8 computer tomographic (CT) images and 15 magnetic resonance images, MRI]. Furthermore, one patient with ILR was identified in our institutional database. Therefore, images of 17 patients were available for further analysis. Overall, 32 cases with ILR were included in the analysis. In most cases acute myeloid leukemia was diagnosed. Most ILRs were localized in the extremities (44 %) and in the extraocular muscles (44 %). Clinically, ILR manifested as local pain, swelling and muscle weakness. Radiologically, ILR presented most frequently with diffuse muscle infiltration. On postcontrast CT/MRI, most lesions demonstrated homogeneous enhancement. ILRs were hypo-/isointense on T1w and hyperintense on T2w images. ILR manifests commonly as focal pain, swelling and muscle weakness. ILR predominantly involved the extraocular musculature and the extremities. Radiologically, diffuse muscle infiltration was the most common imaging finding. (orig.)

    A serious problem experienced by astronauts during long-duration space flight is muscle atrophy. In order to develop countermeasures for this problem, a simple method for monitoring in vivo function of specific muscles is needed. Previous studies document that both intramuscular pressure (IMP) and electromyography (EMG) provide quantitative indices of muscle contraction force during isometric exercise. However, at present there are no data available concerning the usefulness of IMP versus EMG during dynamic exercise. Methods: IMP (Myopress catheter) and surface EMG activity were measured continuously and simultaneously in the tibalis anterior (TA) and soleus (SOL) muscles of 9 normal male volunteers (28-54 years). These parameters were recorded during both concentric and eccentric exercises which consisted of plantarflexon and dorsiflexon of the ankle joint. A Lido Active Isokinetic Dynamometer concurrently recorded ankle joint torque and position. Results: Intramuscular pressure correlated linearly with contraction force for both SOL (r exp 2 = 0.037) and TA (R exp 2 = 0.716 and r exp 2 = 0.802, respectively). During eccentric exercises, SOL and TA IMP also correlated linearly with contraction force (r(exp 2) = 0.883 and r(exp 2) = 0.904 respectively), but SOL and TA EMG correlated poorly with force (r(exp 2) = 0.489 and r(exp 2) = 0.702 respectively). Conclusion: IMP measurement provides a better index of muscle contraction force than EMG during concentric and eccentric exercise. IMP reflects intrinsic mechanical properties of individual muscles, such as length tension relationships. Although invasive, IMP provides a more powerful tool and EMG for developing exercise hardware and protocols for astronauts exposed to long-duration space flight.

    The aim of this study was to evaluate the efficacy and safety of intramuscular midazolam in controlling convulsive status epilepticus in children, by comparing it with rectal diazepam. In this randomized trial, 100 children (50 in each group) with convulsive status epilepticus aged 1 month to 16 years were enrolled and randomly assigned into two groups to receive either 0.3 mg/kg intramuscular midazolam or 0.5 mg/kg rectal diazepam. Main outcome measure was stopping of all motor activity after drug administration. Another measures were times between patient's arrival to emergency department till drug administration, between drug administration to seizure cessation, and between patient's arrival to seizure cessation. Both medication were effective for seizure control and no significant difference was found between successful treatments after administering the medication (P = 0.061). In the midazolam group, in 96% (48/50) of cases treatment was successful and in the diazepam group, in 94% (47/50) of cases treatment was successful. Time from arrival to administering the medication was significantly shorter in midazolam group (P = 0.017). The majority of seizures in midazolam group were stopped in less than 66 s (median) compared to 130 s (median) for diazepam group, (P midazolam is not superior but may be at least as effective as rectal diazepam for controlling of status epilepticus in children. Midazolam via IM route could be one of the choices in children with convulsive status seizures who have difficult IV access. Copyright © 2014 European Paediatric Neurology Society.

    Currently, the definitive diagnosis of chronic compartment syndrome is based on invasive measurements of intracompartmental pressure. We measured the intramuscular pressure and the relative oxygenation in the anterior compartment of the leg in eighteen patients who were suspected of having chronic compartment syndrome as well as in ten control subjects before, during, and after exercise. Chronic compartment syndrome was considered to be present if the intramuscular pressure was at least fifteen millimeters of mercury (2.00 kilopascals) before exercise, at least thirty millimeters of mercury (4.00 kilopascals) one minute after exercise, or at least twenty millimeters of mercury (2.67 kilopascals) five minutes after exercise. Changes in relative oxygenation were measured with use of the non-invasive method of near-infrared spectroscopy. In all patients and subjects, there was rapid relative deoxygenation after the initiation of exercise, the level of oxygenation remained relatively stable during continued exercise, and there was reoxygenation to a level that exceeded the pre-exercise resting level after the cessation of exercise. During exercise, maximum relative deoxygenation in the patients who had chronic compartment syndrome (mean relative deoxygenation [and standard error], -290 +/- 39 millivolts) was significantly greater than that in the patients who did not have chronic compartment syndrome (-190 +/- 10 millivolts) and that in the control subjects (-179 +/- 14 millivolts) (p resting level of oxygenation was significantly longer for the patients who had chronic compartment syndrome (184 +/- 54 seconds) than for the patients who did not have chronic compartment syndrome (39 +/- 19 seconds) and the control subjects (33 +/- 10 seconds) (p < 0.05 for both comparisons).

    Botulinum toxin (BoNT) can relieve muscle spasticity by blocking axon terminals acetylcholine release at the motor endplate (MEP) and is the safest and most effective agent for the treatment of muscle spasticity in children with cerebral palsy. In order to achieve maximum effect with minimum effective dose of BoNT, one needs to choose an injection site as near to the MEP zone as possible. This requires a detailed understanding about the nerve terminal distributions within the muscles targeted for BoNT injection. This study focuses on BoNT treatment in children with muscle spasms caused by cerebral palsy. Considering the differences between children and adults in anatomy, we used child cadavers and measured both the nerve entry points and nerve terminal sense zones in three deep muscles of the anterior forearm: flexor digitorum profundus (FDP), flexor pollicis longus (FPL), and pronator quadratus (PQ). We measured the nerve entry points by using the forearm midline as a reference and demonstrated intramuscular nerve terminal dense zones by using a modified Sihler's nerve staining technique. The locations of the nerve entry points and that of the nerve terminal dense zones in the muscles were compared. We found that all nerve entry points are away from the corresponding intramuscular nerve terminal dense zones. Simply selecting nerve entry points as the sites for BoNT injection may not be an optimal choice for best effects in blocking muscle spasm. We propose that the location of the nerve terminal dense zones in each individual muscle should be used as the optimal target sites for BoNT injection when treating muscle spasms in children with cerebral palsy.

    The aim of this study was to compare the efficacy of oral, intra muscular and transdermal diclofenac sodium for pain treatment in patients undergoing laparoscopic cholecystectomy, and their effect on postoperative opioid consumption. Following informed consent, 90 ASA I-II patients scheduled for laparoscopic cholecystectomy were randomized into three groups. Group PO got oral diclofenac sodium 1 hour before the operation, Group IM 75 mg diclofenac sodium intra muscular and Group TD diclofenac sodium patch 6 hours before the operation. Patients were not premedicated. Routine anaesthesia induction was used. After the operation in post anaesthesia care unit tramadol HCl infusion was delivered by intravenous patient controlled analgesia (iv PCA). Ramsey Sedation Score (RSS), Modified Aldrete's Score System(MASS) and Visual Analog Scale Pain Score (VAS) was used for postoperative evaluation. Postoperative opioid consumption was recorded. Demographic characteristics, intraoperative and postoperative hemodynamics of the patients were similar between groups. Postoperative VAS were lower at all time points in Group IM and Group TD than in Group PO. Lowest Postoperative RSS were in Group IM and the highest were in Group PO, and the difference between groups was significant. There was no significant difference in Postoperative MASS between groups. Postoperative tramadol consumption was statistically different between groups. Tramadol consumption in Group IM and Group TD was lower than Group PO. Postoperative nausea and vomiting was not observed. Local complications related to transdermal and intra muscular applications was not reported. In patients undergoing ambulatory laparoscopic cholecystectomy, a noninvasive application transdermal diclofenac sodium is as effective as intramuscular diclofenac sodium and can be preferred in postoperative pain treatment.

    The Gamma-Ray Large Area Space Telescope (GLAST), set to launch in early 2008, detects gamma rays within a huge energy range of 100 MeV - 300 GeV. Background cosmic radiation interferes with such detection resulting in confusion over distinguishing cosmic from gamma rays encountered. This quandary is resolved by encasing GLAST's Large Area Telescope (LAT) with an Anti-Coincidence Detector (ACD), a device which identifies and vetoes charged particles. The ACD accomplishes this through plastic scintillator tiles; when cosmic rays strike, photons produced induce currents in Photomultiplier Tubes (PMTs) attached to these tiles. However, as GLAST orbits Earth at altitudes {approx}550km and latitudes between -26 degree and 26 degree, it will confront the South Atlantic Anomaly (SAA), a region of high particle flux caused by trapped radiation in the geomagnetic field. Since the SAA flux would degrade the sensitivity of the ACD's PMTs over time, a determined boundary enclosing this region need be attained, signaling when to lower the voltage on the PMTs as a protective measure. The operational constraints on such a boundary require a convex SAA polygon with twelve edges, whose area is minimal ensuring GLAST has maximum observation time. The AP8 and PSB97 models describing the behavior of trapped radiation were used in analyzing the SAA and defining a convex SAA boundary of twelve sides. The smallest possible boundary was found to cover 14.58% of GLAST's observation time. Further analysis of defining a boundary safety margin to account for inaccuracies in the models reveals if the total SAA hull area is increased by {approx}20%, the loss of total observational area is < 5%. These twelve coordinates defining the SAA flux region are ready for implementation by the GLAST satellite.

    Dissecting how genetic and environmental influences impact on learning is helpful for maximizing numeracy and literacy. Here we show, using twin and genome-wide analysis, that there is a substantial genetic component to children's ability in reading and mathematics, and estimate that around one half of the observed correlation in these traits is due to shared genetic effects (so-called Generalist Genes). Thus, our results highlight the potential role of the learning environment in contributing to differences in a child's cognitive abilities at age twelve.

    Direct chromosome analysis and FISH were performed on twelve primary gastric carcinomas. Two of them had simple chromosome changes: 48,XX, +8, +20, and 49, XY, +2, +8, +9, and the others had complicated chromosome changes, which includes much more numerical and structural chromosome aberrations. Frequent structural changes in the complicated types involved chromosome 7, 3, 1, 5 and 12 etc. The del 7q was noted in eight cases. The del (3p) and del (1p) were noted in six and five cases, respectively. The results provide some important clues for isolation of the genes related to gastric cancer.

    BACKGROUND: Recent advancements in gene therapy have provided new methodology for treating ischemia in lower extremities. Gene transfer of angiogenic factors to ischemic tissues may promote local proliferation of new vessels and form collateral circulation. OBJECTIVE: To observe histopathological changes in the femoral and intramuscular nerve three months after intramuscular injection of hepatocyte growth factor (HGF) into the peripheral skeletal muscle in a canine model of lower limb ischemia. DESIGN: Randomized occlusion modelled and verification animal study. SETTING: Experimental Center, Lanzhou General Hospital of Lanzhou Military Area Command of Chinese PLA. MATERIALS: This study was performed at Animal Experimental Center, Lanzhou General Hospital of Lanzhou Military Area Command of Chinese PLA from September to November 2006. A total of eight male mongrel dogs, weighing 12-15 kg and 1.5-3 years of age, were selected for this study. This experimental study was in accordance with local ethics standards. Recombinant plasmid carrying HGF (pUDKH) and occlusion model plasmid (pUDK) were provided by the Third Laboratory of Radiation Medical Institute, Academy of Military Medical Sciences of PLA. METHODS: Grouping and model establishment: under anesthesia, complete vascular occlusion models were established on the left lower extremities. The experimental dogs were randomly divided into a model group and a pUDKH treatment group, with four dogs in each group. Dogs in the pUDKH group were injected with 0.15 mg/kg pUDKH. Ten minutes later, intramuscular injections were performed at three spots into the peripheral skeletal muscle of the left hind limb, as well as lateral injections at two spots. The injection volume at each spot was 0.2 mL. Dogs in the model group were injected with pUDK, and dosage and injection method were identical to the treatment group.MAIN OUTCOME MEASURES: Histopathological changes in the femoral nerve, as well as internal and external

Postmarketing and claims data were analyzed to determine the risk of malignancy in MS patients treated with intramuscular IFNβ-1a.Materials and methods: The cumulative reporting rates of suspected adverse drug reactions coded to malignancy in the intramuscular IFNβ-1a global safety database were compared with malignancy incidence rates in the World Health Organization GLOBOCAN database. In addition, using data from a large US claims database, the cumulative prevalence of malignancy in MS patients treated with intramuscular IFNβ-1a was compared with non-MS population controls, MS patients without intramuscular IFNβ-1a use, and untreated MS patients. Mean follow-up was approximately 3 years for all groups, ie, 3.1 years for the intramuscular IFNβ-1a group (range 0.02–6.0 years, 2.6 years for non-MS population controls (range 0–6.0 years, 2.6 years for the intramuscular IFNβ-1a nonuse group (range 0.01–6.0 years, and 2.4 years for the untreated MS group (range 0.01–6.0 years.Results: An estimated 402,250 patients received intramuscular IFNβ-1a during the postmarketing period. Cumulative reporting rates of malignancy in this population were consistent with GLOBOCAN incidence rates observed within the general population. The claims database included 12,894 MS patients who received intramuscular IFNβ-1a. No significant difference in malignancy prevalence was observed in intramuscular IFNβ-1a users compared with other groups.Conclusion: Results from this evaluation provide no evidence of an increased risk of

    Medetomidine and its active d-enantiomer, dexmedetomidine, are highly selective alpha-2 agonists with potent sedative, anaesthetic-sparing and analgesic effects. These properties make them an ideal pre-anaesthetic medication for noxious surgical procedures. However, sheep can develop adverse hypoxaemic effects after intravenous alpha-2 agonists. Objective of the present study was to compare intramuscular injection of medetomidine or dexmedetomidine at equipotent doses as preanaesthetic medication prior to isoflurane anaesthesia in sheep. Nineteen healthy, adult, non-pregnant, female sheep of various breeds were used. The study was carried out as a randomised, blind trial. Group A received 15 micrograms/kg bwt dexmedetomidine and group B received 30 micrograms/kg bwt medetomidine intramuscularly (i.m.) 30 minutes prior to induction of anaesthesia. Anaesthesia was induced with ketamine (2.0 mg/kg bwt i.v.) and maintained with isoflurane in 100% oxygen. End expired anaesthetic concentration (FEiso), respiratory frequency (fR), direct arterial blood pressures and heart rates (HR) were measured. Arterial blood samples were taken at intervals. Data were averaged over time (sum of measurements/number of measurements) and tested for differences between groups by independent t-tests, and ANOVA for repeated measures followed by Bonferroni corrected t-tests. There were no differences in demographic data between the groups. Duration of anaesthesia [A: 170 (42) minutes, B: 144 (33) minutes] and duration of surgery [A: 92 (32) minutes, B: 85 (31) minutes] were similar in both groups. Average FEiso concentrations required to maintain a surgical plane of anaesthesia were not significantly different between groups [A: 0.82 (0.14)%; B: 1.00 (0.25)%]. Mean average fR, did not differ between groups [A: 31 (14), B: 37 (15)]. Heart rates were significantly lower in group B over the course of the anaesthesia. Mean arterial blood pressures (MAP) were not significantly different between

    A workplace's design can have various positive or negative effects on the employees and since the 1970s the advantages and disadvantages of open-plan offices have been discussed. The aim of this study was to investigate perceived health, work environment and self-estimated productivity one month before and at three, six and twelve months after relocation from individual offices to an open-plan office environment. Employees from three departments within the same company group and who worked with relatively similar tasks and who were planned to be relocated from private offices to open-plan offices were invited to participate. Questionnaires comprising items from The Salutogenic Health Indicator Scale, The Work Experience Measurement Scale, the questionnaire by Brennan et al. about perceived performance and one question from the Work Ability Index were sent to participants one month before relocation (baseline) to open-plan offices and then at three, six and twelve months after relocation. At baseline, 82 questionnaires were sent out. The response rate was 85%. At the follow-ups 77-79 questionnaires were sent out and the response-rate was 70%-81%. At follow-ups, perceived health, job satisfaction and performance had generally deteriorated. The results of the study indicate that employees' perception of health, work environment and performance decreased during a 12 month period following relocation from individual offices to open-plan offices.

    Global surface temperature change is one of the most important aspects in global climate change research. In this study, in order to overcome shortcomings of traditional observation methods in meteorology, a new method is proposed to calculate global mean surface temperature based on remote sensing data. We found that (1) the global mean surface temperature was close to 14.35 °C from 2001 to 2012, and the warmest and coldest surface temperatures of the global in the recent twelve years occurred in 2005 and 2008, respectively; (2) the warmest and coldest surface temperatures on the global land surface occurred in 2005 and 2001, respectively, and on the global ocean surface in 2010 and 2008, respectively; and (3) in recent twelve years, although most regions (especially the Southern Hemisphere) are warming, global warming is yet controversial because it is cooling in the central and eastern regions of Pacific Ocean, northern regions of the Atlantic Ocean, northern regions of China, Mongolia, southern regions of Russia, western regions of Canada and America, the eastern and northern regions of Australia, and the southern tip of Africa. The analysis of daily and seasonal temperature change indicates that the temperature change is mainly caused by the variation of orbit of celestial body. A big data model based on orbit position and gravitational-magmatic change of celestial body with the solar or the galactic system should be built and taken into account for climate and ecosystems change at a large spatial-temporal scale.

    The World Health Organization (WHO) recommends injectable artesunate given either intravenously or by the intramuscular route for definitive treatment for severe malaria and recommends a single intramuscular dose of intramuscular artesunate or intramuscular artemether or intramuscular quinine, in that order of preference as pre-referral treatment when definitive treatment is not possible. Where intramuscular injections are not available, children under 6 years may be administered a single dose of rectal artesunate. Although the current malaria treatment guidelines in Ethiopia recommend intra-rectal artesunate or alternatively intramuscular artemether or intramuscular quinine as pre-referral treatment for severe malaria at the health posts, there are currently no WHO prequalified suppliers of intra-rectal artesunate and when available, its use is limited to children under 6 years of age leaving a gap for the older age groups. Intramuscular artesunate is not part of the drugs recommended for pre-referral treatment in Ethiopia. This study assessed the perspectives of health workers, and policy-makers on the use of intramuscular artesunate as a pre-referral and definitive treatment for severe malaria at the health post level. In-depth interviews were held with 101 individuals including health workers, malaria focal persons, and Regional Health Bureaus from Oromia and southern nations, nationalities, and peoples' region, as well as participants from the Federal Ministry of Health and development partners. An interview guide was used in the data collection and thematic content analysis was employed for analysis. Key findings from this study are: (1) provision of intramuscular artesunate as pre-referral and definitive treatment for severe malaria at health posts could be lifesaving; (2) with adequate training, and provision of facilities including beds, health posts can provide definitive treatment for severe malaria using intramuscular artesunate where referral is

    Hepatitis C virus (HCV) affects millions of individuals worldwide. In most cases, HCV infection progresses to chronic liver disease and, subsequently, to liver cirrhosis and hepatocellular carcinoma. HCV is transmitted by the parenteral route, for example by transfusion of blood or blood products, injection during drug abuse, etc., and by the inapparent parenteral route (penetration of the virus through difficult-to-identify microlesions present on the skin or mucosae), for example, sexual exposure or household exposure to infected contacts, etc. The cost of chronic hepatitis C and its sequelae is high in both financial and human terms. At present, only anti-HCV screening of blood/organ/tissue donors and universal precautions for the prevention of blood-borne infections are recommended for HCV prevention. Before the discovery of the main aetiological agent of non-A, non-B hepatitis (HCV), several randomised controlled clinical trials demonstrated that standard intramuscular immunoglobulin exerted a preventive effect on post-transfusional and sexual and /or horizontal transmission of non-A, non-B hepatitis. When serological tests for HCV infection became available, bimonthly inoculation of standard unscreened intramuscular immunoglobulin (prepared from plasma pools containing about 2% of anti-HCV-positive units) was demonstrated to significantly prevent sexually transmitted HCV infection. The immunoglobulin used contained high titres of anti-HCV neutralising antibodies (anti-E2 neutralisation of binding assay), whereas currently available commercial screened immunoglobulin (prepared from anti-HCV-negative blood units) did not. This finding suggested that anti-HCV neutralising antibodies are concentrated only in anti-HCV-positive units (which are currently discarded). Thus, anti-HCV hyperimmune globulin (HCIg) can be produced only from anti-HCV-positive units. The neutralising titre can be increased by the exclusive use of units with higher titres of neutralising

    Pharmacokinetics of difloxacin, a fluoroquinolone antibiotic, was determined in pigs and broilers after intravenous (i.v.), intramuscular (i.m.), or oral (p.o.) administration at a single dose of five (pigs) or 10 mg/kg (broilers). Plasma concentration profiles were analyzed by a compartmental pharmacokinetic method. Following i.v., i.m. and p.o. doses, the elimination half-lives (t(1/2beta)) were 17.14 +/- 4.14, 25.79 +/- 8.10, 16.67 +/- 4.04 (pigs) and 6.11 +/- 1.50, 5.64 +/- 0.74, 8.20 +/- 3.12 h (broilers), respectively. After single i.m. and p.o. administration, difloxacin was rapidly absorbed, with peak plasma concentrations (C(max)) of 1.77 +/- 0.66, 2.29 +/- 0.85 (pigs) and 2.51 +/- 0.36, 1.00 +/- 0.21 microg/mL (broilers) attained at t(max) of 1.29 +/- 0.26, 1.41 +/- 0.88 (pigs) and 0.86 +/- 0.4, 4.34 +/- 2.40 h (broilers), respectively. Bioavailabilities (F) were (95.3 +/- 28.9)% and (105.7 +/- 37.1)% (pigs) and (77.0 +/- 11.8)% and (54.2 +/- 12.6)% (broilers) after i.m. and p.o. doses, respectively. Apparent distribution volumes(V(d(area))) of 4.91 +/- 1.88 and 3.10 +/- 0.67 L/kg and total body clearances(Cl(B)) of 0.20 +/- 0.06 and 0.37 +/- 0.10 L/kg/h were determined in pigs and broilers, respectively. Areas under the curve (AUC), the half-lives of both absorption and distribution(t(1/2ka), t(1/2alpha)) were also determined. Based on the single-dose pharmacokinetic parameters determined, multiple dosage regimens were recommended as: a dosage of 5 mg/kg given intramuscularly every 24 h in pigs, or administered orally every 24 h at the dosage of 10 mg/kg in broilers, can maintain effective plasma concentrations with bacteria infections, in which MIC(90) are <0.25 microg/mL and <0.1 microg/mL respectively.

    Simple Summary Physical castration (PC) of piglets is a painful and stressful procedure and alternatives are being sought to improve animal well-being, such as immunological castration (IC). However, IC requires injections which may also cause pain and stress during handling. In this study, piglets and finishing pigs were placed in the following treatment groups: no handling or treatment (NO), sham-handling (SHAM), intramuscular injection (IM), subcutaneous injection (SQ), or PC on piglets only. Behavior was monitored for 1 h prior and 1 h post treatment in each age group. Social behavior and feeding behavior, and signs of pain were recorded. Physical castration caused measurable pain-like behaviors and general behavioral dysregulation at a much higher level than changes associated with handling associated with IM or SQ injections. Overall, injections did not cause a change in weaning pig behaviors. Finishing pigs given SQ injections showed a lower number of feeding behaviors post treatment but other changes were not observed in the other treatment groups. Abstract Physical castration (PC) is painful and stressful for nursing piglets. One alternative to PC is immunological castration (IC), but the pain and stress of handling associated with injections have not been assessed. The objectives of this study were to measure the pain and distress of subcutaneous (SQ) and intramuscular (IM) injections compared to PC in piglets, and to compare SQ or IM injections in finishing pigs. After farrowing, 3 to 5 d old male piglets were randomly assigned to (control) no handling treatment (NO), sham-handling (SHAM), IM, SQ, or PC. Finishing pigs were assigned to NO, SHAM, IM, or SQ. Behavior was monitored for 1 h prior and 1 h post treatment in each age group. Social, feeding behaviors, and signs of pain were recorded. Finishing pigs treated with SQ injections had higher feeding behaviors pre-treatment than they did post-treatment. Overall, physical castrations caused measurable

    Background Intravenous (IV), intramuscular (IM), and subcutaneous (SC) are the three most frequently used injection routes in medication administration. Comparative studies of SC versus IV, IM versus IV, or IM versus SC have been sporadically conducted, and some new findings are completely different from the dosage recommendation as described in prescribing information. However, clinicians may still be ignorant of such new evidence-based findings when choosing treatment methods. Methods A literature search was performed using PubMed, MEDLINE, and Web of Sciences™ Core Collection to analyze the advantages and disadvantages of SC, IV, and IM administration in head-to-head comparative studies. Results “SC better than IV” involves trastuzumab, rituximab, antitumor necrosis factor medications, bortezomib, amifostine, recombinant human granulocyte-macrophage colony-stimulating factor, granulocyte colony-stimulating factor, recombinant interleukin-2, immunoglobulin, epoetin alfa, heparin, and opioids. “IV better than SC” involves ketamine, vitamin K1, and abatacept. With respect to insulin and ketamine, whether IV has advantages over SC is determined by specific clinical circumstances. “IM better than IV” involves epinephrine, hepatitis B immu-noglobulin, pegaspargase, and some antibiotics. “IV better than IM” involves ketamine, morphine, and antivenom. “IM better than SC” involves epinephrine. “SC better than IM” involves interferon-beta-1a, methotrexate, human chorionic gonadotropin, hepatitis B immunoglobulin, hydrocortisone, and morphine. Safety, efficacy, patient preference, and pharmacoeconomics are four principles governing the choice of injection route. Safety and efficacy must be the preferred principles to be considered (eg, epinephrine should be given intramuscularly during an episode of systemic anaphylaxis). If the safety and efficacy of two injection routes are equivalent, clinicians should consider more about patient preference and

    1.The aim of the present study was to determine the PKs of marbofloxacin in beagle dogs after intravenous (i.v.) and intramuscular (i.m.) administration, the ex vivo and in vitro PK/PD indices of marbofloxacin against clinical isolates of Staphylococcus pseudintermedius, and the ex vivo AUC/MIC ratios associated with different levels of antibacterial activity. 2.After i.v. of marbofloxacin (2 mg/kg), the mean ± SEM values of AUC, t1/2β, Vss, and CL were 8.47 ± 3.51 h µg/mL, 8.08 ± 6.25 h, 2.32 ± 1.00 L/kg and 0.23 ± 0.06 L/kg/h and corresponding values after intramuscular injection were 11.37 ± 3.07 h µg/mL, 7.51 ± 3.70, 1.80 ± 0.90 L/kg and 0.17 ± 0.04 L/kg/h. After i.m. administration, a Cmax of 1.76 ± 0.09 µg/mL was achieved at Tmax of 0.47 ± 0.08 h. The ex-vivo AUC/MIC ratios required to produce bacteriostasis, bactericidal action and elimination of S. pseudintermedius were 65.03, 97.02 and 136.84 h. 3.The in vivo AUC/MIC ratios obtained after i.v. and i.m. administration of 2 mg/kg marbofloxacin (67.76 ± 1.23 and 91.18 ± 2.61) were below the ex vivo AUC/MIC ratios required for bactericidal activity and bacterial elimination (97.02 ± 9.24 2 mg/kg and 136.21 ± 7.58), suggesting that the recommended daily dosage (2 mg/kg) may not suffice to kill and eradicate S. pseudintermedius strains encountered in clinical area.

    Testosterone replacement therapy results in decreased serum gonadotropins and intratesticular testosterone, and impairs spermatogenesis, leading to azoospermia in 40% of patients. However, intratesticular testosterone can be maintained during testosterone replacement therapy with co-administration of low dose human chorionic gonadotropin, which may support continued spermatogenesis in patients on testosterone replacement therapy. We retrospectively reviewed the records of hypogonadal men treated with testosterone replacement therapy and concomitant low dose human chorionic gonadotropin. Testosterone replacement consisted of daily topical gel or weekly intramuscular injection with intramuscular human chorionic gonadotropin (500 IU) every other day. Serum and free testosterone, estradiol, semen parameters and pregnancy rates were evaluated before and during therapy. A total of 26 men with a mean age of 35.9 years were included in the study. Mean followup was 6.2 months. Of the men 19 were treated with injectable testosterone and 7 were treated with transdermal gel. Mean serum hormone levels before vs during treatment were testosterone 207.2 vs 1,055.5 ng/dl (p testosterone 8.1 vs 20.4 pg/ml (p = 0.02) and estradiol 2.2 vs 3.7 pg/ml (p = 0.11). Pretreatment semen parameters were volume 2.9 ml, density 35.2 million per ml, motility 49.0% and forward progression 2.3. No differences in semen parameters were observed during greater than 1 year of followup. No impact on semen parameters was observed as a function of testosterone formulation. No patient became azoospermic during concomitant testosterone replacement and human chorionic gonadotropin therapy. Nine of 26 men contributed to pregnancy with the partner during followup. Low dose human chorionic gonadotropin appears to maintain semen parameters in hypogonadal men on testosterone replacement therapy. Concurrent testosterone replacement and human chorionic gonadotropin use may preserve fertility in hypogonadal males

    Full Text Available To study age-related variations in fatty acid composition of covering and intramuscular fat (IMF, 60 half siblings, Pic X Camborough, of the same age, 30 barrows and 30 gilts, chosen from 10 litters were used. Groups of 20 subjects each, 10 castrated males and 10 females, balanced for litter, were sacrificed at 6, 8.5 and 9.5 months of age, corresponding to the common slaughter age of the three Italian pig production types, at live weights averaging approximately 90, 145 and 160 kg, respectively. Samples of backfat and longissimus thoracis (LT muscle, taken at the last rib, were analysed. On LT samples, moisture, fat content and drip loss were determined. Fatty acid composition was determined in lipids from subcutaneous adipose tissue and in lipid fractions from LT. Further, backfat lipids were submitted to iodine value (I.V. determination. The data were evaluated by means of analysis of variance with age at slaughter and sex as the independent variables. As age increased (6, 8.5 and 9.5 months, higher contents of saturated fatty acids (SFA (36.36, 39.08 and 39.19%, respectively; P<0.01 and monounsaturated fatty acids (MUFA (41.78, 43.44 and 44.37%, respectively; P<0.01 were observed in backfat, whereas polyunsaturated fatty acids (PUFA content, PUFA/SFA ratio and I.V. lowered (P<0.01. As total IMF is concerned, by increasing age, MUFA content increased (43.30; 46.76 and 47.28%, respectively; P<0.01, PUFA content decreased (18.63, 15.14 and 14.82%, respectively; P<0.01 and PUFA/SFA decreased as well (P<0.05; neutral lipids followed the same pattern, while an opposite trend was observed in polar lipids. IMF content (1.65% was modified neither by sex nor age. The study shows that fatty acids composition of subcutaneous and intramuscular fats differs among the 3 slaughtering ages typical of the Italian pig industry. The variations observed, which could be ascribed to the increase of carcass fatness at increasing slaughter age, can affect both the

    We herein present a case of acquired hemophilia A with a normal activated partial thromboplastin (aPTT), intramuscular hematoma and cerebral hemorrhage occurring in a 73-year-old man. The patient visited our emergency department with gait disturbance, pain and swelling in his right leg. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed intramuscular hematoma and intracranial hemorrhage. The results of initial coagulation studies were normal, but repeated coagulation studies revealed an isolated prolongation of the aPTT. Additional laboratory tests confirmed the diagnosis of acquired hemophilia A. If the initial aPTT is normal, we should therefore repeat the aPTT and also perform other coagulation studies including a mixing study, factor VIII level and inhibitor, to investigate the underlying diseases in elderly patients with spontaneous hemorrhaging of unknown etiology.

  20. 'Serious thigh muscle strains': beware the intramuscular tendon which plays an important role in difficult hamstring and quadriceps muscle strains.

    Brukner, Peter; Connell, David

    2016-02-01

    Why do some hamstring and quadriceps strains take much longer to repair than others? Which injuries are more prone to recurrence? Intramuscular tendon injuries have received little attention as an element in 'muscle strain'. In thigh muscles, such as rectus femoris and biceps femoris, the attached tendon extends for a significant distance within the muscle belly. While the pathology of most muscle injures occurs at a musculotendinous junction, at first glance the athlete appears to report pain within a muscle belly. In addition to the musculotendinous injury being a site of pathology, the intramuscular tendon itself is occasionally injured. These injuries have a variety of appearances on MRIs. There is some evidence that these injuries require a prolonged rehabilitation time and may have higher recurrence rates. Therefore, it is important to recognise the tendon component of a thigh 'muscle strain'.

    Motor control and learning possibilities of scapular muscles are of clinical interest for restoring scapular muscle balance in patients with neck and shoulder disorders. The aim of the study was to investigate whether selective voluntary activation of intra-muscular parts within the serratus...... anterior can be learned with electromyographical (EMG) biofeedback, and whether the lower serratus anterior and the lower trapezius muscle comprise the lower scapula rotation force couple by synergistic activation. Nine healthy males practiced selective activation of intra-muscular parts within...... to selectively activate the lower serratus anterior, and two subjects learned to selectively activate the upper serratus anterior. During selective activation of the lower serratus anterior, the activity of this muscle part was 14.4+/-10.3 times higher than the upper serratus anterior activity (P

    In the present study, we proposed an original and robust methodology which combines the spatial normalization of skeletal muscle images, the statistical parametric mapping (SPM) analysis and the use of a specific parcellation in order to accurately localize and quantify the extent of skeletal muscle damage within the four heads of the quadriceps femoris. T2 maps of thigh muscles were characterized before, two (D2) and four (D4) days after 40 maximal isometric electrically-evoked contractions in 25 healthy young males. On the basis of SPM analysis of coregistrated T2 maps, the alterations were similarly detected at D2 and D4 in the superficial and distal regions of the vastus medialis (VM) whereas the proportion of altered muscle was higher in deep muscle regions of the vastus lateralis at D4 (deep: 35 ± 25%, superficial: 23 ± 15%) as compared to D2 (deep: 18 ± 13%, superficial: 17 ± 13%). The present methodology used for the first time on skeletal muscle would be of utmost interest to detect subtle intramuscular alterations not only for the diagnosis of muscular diseases but also for assessing the efficacy of potential therapeutic interventions and clinical treatment strategies.

    1988-06-01

    The pharmacokinetic properties of a long-acting formulation of chloramphenicol were determined in six yearling cattle after a single intravenous (i.v.) administration (40 mg/kg body weight) and after two sequential subcutaneous (s.c.) or intramuscular (i.m.) administrations (90 mg/kg/48 h). The two extravascular routes were studied during a crossover trial for a bioequivalence test. After i.v. administration, the plasma concentration-time graph was characteristic of a two-compartment open model. Mean values were a half-life of 4.1 h, a volume of distribution of 0.86 l/kg and a body clearance of 0.128 l/kg/h. Plasma concentrations of chloramphenicol following i.m. and s.c. administrations increased slowly to a broad peak at 10-15 micrograms/ml between 9 and 12 h. Bioavailability was 19.1% after i.m. injection and 12.4% after s.c. administration. The extent of absorption from the two routes did not differ significantly. The rate of absorption was significantly lower after s.c. application than it was after i.m. injection. The time necessary for the plasma concentration to exceed 5 micrograms/ml was the same for the two routes. Thus, i.m. and s.c. routes are bioequivalent.

    2011-10-01

    This paper presents a density-based method to automatically decompose single-channel intramuscular electromyogram (EMG) signals into their component motor unit action potential (MUAP) trains. In contrast to most previous decomposition methods, which require pre-setting and (or) tuning of multiple parameters, the proposed method takes advantage of the data-dependent strategies in the pattern recognition procedures. In this method, outliers (superpositions) are excluded prior to classification and MUAP templates are identified by an adaptive density-based clustering procedure. MUAP trains are then identified by a novel density-based classifier that incorporates MUAP shape and discharge time information. MUAP trains are merged by a fuzzy system that incorporates expert human knowledge. Finally, superimpositions are resolved to fill the gaps in the MUAP trains. The proposed decomposition algorithm has been experimentally tested on signals from low-force (muscles. Comparison with expert manual decomposition that had been verified using a rigorous statistical analysis showed that the algorithm identified 80% of the total 229 motor unit trains with an accuracy greater than 90%. The algorithm is robust and accurate, and therefore it is a promising new tool for decomposing single-channel multi-unit signals.

    Full Text Available Bacillus Calmette-Guérin (BCG is indicated for treatment of primary or relapsing flat urothelial cell carcinoma in situ (CIS of the urinary bladder. Disseminated infectious complications occasionally occur due to BCG as a vaccine and intravesical therapy.  Intramuscular (IM or Intravenous (IV administrations of BCG are rare medication errors which are more probable to produce systemic infections. This report presents 13 years old case that several steps medication errors occurred consequently from physician handwriting, pharmacy dispensing, nursing administration and patient family. The physician wrote βHCG instead of HCG in the prescription. βHCG was read as BCG by the pharmacy staff and 6 vials of intravesical BCG were administered IM twice a week for 3 consecutive weeks. The patient experienced fever and chills after each injection, but he was admitted 2 months after first IM administration of BCG with fever and pancytopenia. Unfortunately four month after using drug, during second admission duo to cellulitis at the sites of BCG injection the physicians diagnosed the medication error. Using handwritten prescription and inappropriate abbreviations, spending inadequate time for taking a brief medical history in pharmacy, lack of verifying name, dose and wrote before medication administration and lack of considering medication error as an important differential diagnosis had roles to occur this multi-steps medication error.

  6. Relationship between muscle stress and intramuscular pressure during dynamic muscle contractions.

    2007-09-01

    Intramuscular pressure (IMP) has been used to estimate muscle stress indirectly. However, the ability of this technique to estimate muscle stress under dynamic conditions is poorly characterized. Therefore, the purpose of this study was to determine the extent to which IMP is a valid surrogate for muscle stress during dynamic contractions. IMP and muscle stress were compared under steady-state isotonic conditions and during complex dynamic length changes. During concentric contractions the shape of the IMP-velocity curve mimicked the basic shape of the force-velocity curve but with much higher variability. For eccentric contractions, a precipitous drop in IMP was observed despite increased muscle stress. The dissociation between muscle stress and IMP during dynamic contractions was partially explained by sensor movement. When the muscle was not moving, IMP explained 89% +/- 5% of the variance in muscle force. However, when transducer movement occurred the linear relationship between IMP and stress was no longer observed. These findings demonstrate the difficulty in interpreting IMP under dynamic conditions when sensor movement occurs. They also illustrate the need to control transducer movement if muscle stress is to be inferred from IMP measurements such as might be desired during clinical gait testing.

    During sustained static contractions an increase in the root mean square (rms) amplitude and a decrease in mean power frequency (MPF), or median power frequency (MF) of the electromyographic (EMG) signal are indicators for the development of muscle fatigue. However, when studying dynamic contractions the interpretation of these variables has been questioned. Therefore, the purpose was to compare the EMG variables recorded from a non-fatigued muscle during a slow low level dynamic contraction to those during a static contraction of similar force level. Surface and intramuscular EMG registrations were obtained from the brachial biceps muscle during: (a) a static isotonic contraction, (b) a dynamic contraction and (c) a static anisotonic contraction. During contractions (a) and (b) the recruitment pattern was analysed using the precision decomposition method. No differences in rms, MPF or MF between the dynamic and static contractions or between the concentric and eccentric phase of the dynamic contraction were found. Furthermore 60% of the identified motor units were active both in the concentric and the eccentric phase. This indicates that motor control during a slow dynamic contraction at low force level does not influence the power spectrum. We suggest that in occupational studies a possible muscle fatigue development with time can be estimated using EMG recordings from the work tasks.

    Full Text Available Pain in neonates can be associated with various risks and it seems essential to find a simple and acceptable method for relieving pain. Pharmacologic agents are not recommended in neonates for pain relief in minor procedures but orally administered glucose solution is found to be effective. The objective of this study was to assess the efficacy of oral 30% glucose during intramuscular injection in term neonates. Sixty-four healthy term neonates were recruited for this study during 1 month. The inclusion criteria were gestational age 37-42 weeks, birth weight 2500-4000 gr, and Apgar score > 7. The intervention consists of administration of either 2 ml of oral 30% glucose or 2ml of sterile water 2 minutes before injection. The primary out come measure was the cumulative Neonatal Infant Pain Scale (NIPS score at 3 minutes after injection. Thirty-two neonates received 30% glucose and 32 neonates received sterile water. The cumulative NIPS score at 3 minutes after injection for neonates given 30% glucose was significantly (P = 0.000 lower than for neonates given sterile water. The heart rate immediately after injection for neonates given 30% glucose was significantly (P = 0.002 lower than for neonates given sterile water. Oral 30% glucose given 2 minutes before injection was effective in reducing neonatal pain following injection. It is a simple, safe and fast acting analgesic and should be considered for minor invasive procedures in term neonates.

    The significant expansion in the use of nanoparticles and submicron particles during the last 20 years has led to increasing concern about their potential toxicity to humans and particularly their impact on male fertility. Currently, an insufficient number of studies have focused on the testicular biodistribution of particles. The aim of our study was to assess the distribution of 450 nm fluorescent particles in mouse testes after intramuscular injection. To this end, testes were removed from 5 groups of 3 mice each at 1 h (H1), 4 days (D4), 21 days (D21), 45 days (D45) and 90 days (D90) after the injection of 7.28 × 10⁹ particles in the tibialis anterior muscles of each mouse. We examined histological sections from these samples by epifluorescence microscopy and confocal microscopy and identified testicular biodistribution of a small number of particles in groups H1, D4, D21, D45 and D90. Using CD11b immunostaining, we showed that particles were not carried into the testis by macrophages. The intratesticular repartition of particles mainly followed testicular vascularization. Finally, we found some particles in seminiferous tubules but could not determine if the blood-testis barrier was crossed.

    Full Text Available The purpose of the study was to determine whether uniform intramuscular heating is achieved throughout a treatment area 2 times the transducer head at both 1 and 3 MHz. Seven male and three female subjects (Age: 23.6 ± 1.0 yrs, Weight: 83.8 ± 23.2 kg, Site Skinfold: 13.9 ± 7.3 mm underwent two ultrasound treatments (1 and 3 MHz in the triceps surae muscle group. Thermocouples were inserted at the midpoint and periphery of the treatment area. Ten minute baseline temperatures were recorded followed by a ten minute ultrasound treatment. Two (site X 10 (time repeated measures ANOVAs were separately used to determine significance for 1 and 3 MHz treatments. Post-hoc testing was performed using the Bonferroni adjustment. A significant site-by-time interaction was observed for both the 1 and 3 MHz treatments. From baseline to the end of the treatment, temperature increased approximately 2.62°C and 1.58°C for the midpoint and periphery of the 1 MHz treatment and 5.88°C and 3.64°C for the 3 MHz treatment. The differences in temperature suggest that uniform heating does not occur throughout the treatment area

    Gluteus minimus is believed to consist of two structurally and functionally unique segments (anterior and posterior); however there is a lack of electromyography (EMG) research that attempts to verify current theoretical knowledge of this muscle. The purpose of this study was therefore to evaluate the function of gluteus minimus during gait, and to determine whether anterior and posterior segments are functionally independent. Bipolar fine wire intramuscular EMG electrodes were inserted into anterior and posterior gluteus minimus segments of fifteen healthy volunteers (9 males) according to previously verified guidelines. Participants completed a series of four walking trials, followed by maximum voluntary isometric contractions in five different positions. Temporal and amplitude variables for each segment were compared across the gait cycle with independent t-tests. The relative contribution of each segment to the maximum resisted trials was compared with Mann-Whitney U tests (α = 0.05). Anterior and posterior segments were contracting at different relative intensities for three of the five maximum resisted trials (effect size = 0.39 to 0.62, P gait cycle (effect size = 0.96 to 1.03, P phase (effect size = 0.83, P = 0.034). Gluteus minimus is therefore composed of functionally independent segments. These results build on contemporary theoretical knowledge and may signify hip stabilising roles for each segment across different phases of the gait cycle.

    Fat deposition is a complex process involving proliferation, differentiation, and lipogenesis of adipocytes. Bamei and Landrace are considered to represent fat- and lean-type pig breeds. Subcutaneous (SC) and intramuscular (IM) pre-adipocytes were cultured to compare the proliferation and lipogenesis in these breeds. The differentiated adipocytes were exposed to glucose or insulin to evaluate their effects on lipogenesis and lipogenic gene expression. Pre-adipocytes proliferated dramatically faster in SC vs. IM cells, and in Bamei vs. Landrace breeds. Lipogenesis and lipogenic gene expression had a greater increase in Bamei than in Landrace, and in SC vs. IM in the process of differentiation. Glucose markedly promoted lipogenesis and lipogenic gene expression in differentiated adipocytes. The stimulation of high-glucose levels on lipogenesis and ChREBP and lipogenic gene expression was higher in SC than IM adipocytes, and in Bamei vs. Landrace. Insulin largely increased SREBP-1c expression, however it modestly stimulated lipogenesis and lipogenic gene expression, and there was no difference between cell populationsor between breeds. These data demonstrated that regional and varietal differences obviously existed in the development of porcine adipocytes. The proliferation and differentiation capacity of pre-adipocytes, and the adipocyte lipogenesis stimulated by glucose, are stronger in Bamei than Landrace, and in SC vs. IM adipocytes independent of breed.

    Intramuscular fat (IMF) is one of the main parameters affecting meat quality. This work analyzes the effect of selection for IMF on sensory attributes and instrumental texture parameters in rabbit meat. A total of 115 rabbits after 6 generations of divergent selection for IMF were slaughtered at 9 or 13 wk (57 and 58 animals, respectively). For each animal, the left longissimus dorsi muscle (LD) was analyzed by near-infrared spectroscopy to measure IMF whereas the right LD was used for the sensory or instrumental texture analysis. Sensory attributes measured were rabbit odor, liver odor, rabbit flavor, liver flavor, aniseed flavor, hardness, juiciness, and fibrousness. The instrumental texture parameters maximum shear force, shear firmness, and total work to cut the sample were measured by a Warner-Bratzler shear test. The line selected for high IMF showed 58% greater IMF than the line selected for low IMF. This divergence affected firmness that was 9.9% greater in the low-IMF line, although no effect was found for the other instrumental texture traits. No effect of selection was observed in any odor or flavor, except for aniseed flavor, which was greater in the high-IMF line than in the low-IMF line. Age had an effect on IMF, instrumental texture parameters, and sensory attributes. Rabbits at 13 wk showed greater IMF and instrumental and sensory hardness and more intense odor and flavor and lower juiciness than rabbits at 9 wk.

    Intramuscular fat (IMF) content contributes to meat flavor and improves meat quality. Excessive abdominal fat, however, leads to a waste of feed resources. Here, an independent up-selection for IMF was used as a control (Line C), and a balanced selection program, with up-selection for IMF and down-selection AFP (Line B), was studied in JingXing yellow chickens. The mean of IMF and AFP within a family was the phenotypic value upon which selection was based. The selective pressures of IMF in line B and line C were the same in each generation. At G5, the IMF was significantly higher (P  0.05). IMF increased by 11.4% and AFP decreased by 1.5% in Line B compared with the G0 generation. In contrast, the IMF increased by 17.6%, but was accompanied by an 18.7% increase in AFP, in control Line C. Of 10 other traits measured, body weight at 56 d age (BW56) and the percentages of eviscerated weight (EWP) showed a significant difference between the 2 lines (P IMF and AFP, estimated by the DMU package, were 0.16 and 0.32, respectively. A moderate positive correlation existed between IMF and AFP (0.35). A balanced selection program for increasing IMF while controlling AFP (Line B) is shown here to be effective in practical chicken breeding. © 2016 Poultry Science Association Inc.

    The aim of this study is to identify SNPs and genes related to pig IMF and estimate the heritability of IMF. Genome-wide association study (GWAS) on 704 inbred Berkshires was performed for intramuscular fat content (IMF). To consider the inbreeding among samples, associations of the SNPs with IMF were tested as random effects in a mixed linear model using the genetic relationship matrix by GEMMA. Significant genes were compared with reported pig IMF QTL regions and functional classification of the identified genes were also performed. Heritability of IMF was estimated by GCTA tool. Total 365 SNPs were found to be significant from a cutoff of p-value IMF QTL regions. BMPER, FOXO1, EDAR, RNF149, CD40, PTPN1, SOX9, MYC, MIF were related to mitogen-activated protein kinase (MAPK) pathway which regulates the differentiation to adipocytes. These genes and the genes mapped on QTLs could be the candidate genes affecting IMF. Heritability of IMF was estimated as 0.52, which was relatively high, suggesting that a considerable portion of the total variance of IMF is explained by the SNP information. Our results can contribute to breeding pig with better IMF and therefore, producing pork with better sensory qualities.

    The disposition kinetics of tylosin tartrate administered intravenously (i.v.) at 10 mg/kg and intramuscularly (i.m.) at 20 mg/kg were studied in normal camels and in the same camels at the end of a 14 day water-deprivation period. After i.v. treatment, serum tylosin concentrations in the water-deprived camels were significantly higher, rate of drug elimination was slower, the volume of distribution was significantly smaller, and total body clearance was significantly slower than in the normal camels. On the other hand, serum drug concentrations were lower in the water deprived camels after i.m. dosing, the mean absorption time was significantly shorter and the i.m. availability was significantly smaller than in the normal camels. Water-deprivation was thought to cause reduced rate of tylosin elimination by the liver, as was shown for antipyrine--a drug which is eliminated from the body exclusively by the liver. Redistribution of tylosin in tissues concomitant with a greater proportion of drug in blood and extracellular fluid of water-deprived camels was suggested as a partial explanation for the higher serum drug levels seen after i.v. dosing. The low i.m. availability observed in the water-deprived camels implies that i.v. is the route of choice for tylosin administration to ill, dehydrated camels.

    Insulin-induced gene 2 (INSIG2) single-nucleotide polymorphism (SNP rs7566605) is linked to lipid metabolism, and this study assessed its potential influence on fat in the upper arm following arm training. Twenty healthy sedentary volunteers (22.0 ± 1.1 years, body mass index 25.4 ± 4.0 kg/m(2......) ; mean ± standard deviation) carried out a 12-week two-arm elbow extensor training (10 maximal extensions with 1 min recovery between bouts) five times per day, five times per week. For 17 volunteers, upper arm muscle and adipose tissue [subcutaneous (SCAT) and intramuscular (IMAT)] volumes were...... evaluated by magnetic resonance imaging before, immediately after, and 12 months after training and variables were related to the subjects' INSIG2 SNP rs7566605 genotype. Muscle volume and SCAT for the upper arm, as the decrease in IMAT during training were not related to INSIG2 SNP rs7566605: GG: %IMAT 1...

    A better understanding of skeletal muscle lipid metabolism is needed to identify the molecular mechanisms relating intramuscular triglyceride (IMTG) to muscle metabolism and insulin sensitivity. An increasing number of proteins have been reported to be associated with intracellular triglyceride (TG), among them the PAT family members: perilipin, ADRP (for adipocyte differentiation-related protein), and TIP47 (for tail-interacting protein of 47 kDa). Hormone-sensitive lipase (HSL) is thought to be the major enzyme responsible for IMTG hydrolysis in skeletal muscle. In adipocytes, regulation of HSL by intracellular redistribution has been demonstrated. The existence of such regulatory mechanisms in skeletal muscle has long been hypothesized but has never been demonstrated. The aim of this study was to characterize the PAT family proteins associated with IMTG and to investigate the effect of epinephrine stimulation or muscle contraction on skeletal muscle TG content and HSL intracellular distribution. Rat soleus muscles were either incubated with epinephrine or electrically stimulated for 15 min. Single muscle fibers were used for morphological analysis by confocal and transmission electron microscopy. We show a decrease in IMTG in response to both lipolytic stimuli. Furthermore, we identify two PAT family proteins, ADRP and TIP47, associated with IMTG. Finally, we demonstrate HSL translocation to IMTG and ADRP after stimulation with epinephrine or contraction.

    Maternal nutrition is important for the risk of the offspring to develop insulin resistance and adiposity later in life. The study was undertaken to determine effects of maternal butyrate supplementation on lipid metabolism and insulin sensitivity in the offspring skeletal muscle. The offspring of rats, fed a control diet or a butyrate diet (1% sodium butyrate) throughout gestation and lactation, was studied at weaning and at 60 days of age. The offspring of dams fed a butyrate diet had higher HOMA-insulin resistance and impaired glucose tolerance. This was associated with elevated mRNA and protein expressions of lipogenic genes and decreased amounts of lipolytic enzyme. Simultaneously, enhanced acetylation of histone H3 lysine 9 and histone H3 lysine 27 modification on the lipogenic genes in skeletal muscle of adult offspring was observed. Higher concentration of serum insulin and intramuscular triglyceride in skeletal muscle of offspring from the butyrate group at weaning were accompanied by increasing levels of lipogenic genes and enrichment of acetylation of histone H3 lysine 27. Maternal butyrate supplementation leads to insulin resistance and ectopic lipid accumulation in skeletal muscle of offspring, indicating the importance of short chain fatty acids in the maternal diet on lipid metabolism.

    Intramuscular fat percentage (IMF%) has been shown to have a positive influence on the eating quality of red meat. Selection of Australian lambs for increased lean tissue and reduced carcass fatness using Australian Sheep Breeding Values has been shown to decrease IMF% of the Muscularis longissimus lumborum. The impact this selection has on the IMF% of other muscle depots is unknown. This study examined IMF% in five different muscles from 400 lambs (M. longissimus lumborum, Muscularis semimembranosus, Muscularis semitendinosus, Muscularis supraspinatus, Muscularis infraspinatus). The sires of these lambs had a broad range in carcass breeding values for post-weaning weight, eye muscle depth and fat depth over the 12th rib (c-site fat depth). Results showed IMF% to be highest in the M. supraspinatus (4.87 ± 0.1, Plambs born as multiples and raised as singles. For each per cent increase in lean meat yield percentage (LMY%), there was a reduction in IMF% of 0.16 in all five muscles examined. Given the drive within the lamb industry to improve LMY%, our results indicate the importance of continued monitoring of IMF% throughout the different carcass regions, given its importance for eating quality.

    The pharmacokinetic properties of ketoprofen were determined in 4-week-old calves after intramuscular (i.m.) injection of a racemic mixture at a dose of 3 mg/kg body weight. Due to possible enantioselective disposition kinetics and chiral inversion, the plasma concentrations of the R(-) and S(+) enantiomer were quantified separately, using a stereospecific HPLC-UV assay. A distinct predominance of the S(+) enantiomer was observed, as well as significantly different pharmacokinetic parameters between R(-) and S(+) ketoprofen. More in specific, a greater value for the mean area under the plasma concentration-time curve (AUC(0→∞)) (46.92 ± 7.75 and 11.13 ± 2.18 μg·h/mL for the S(+) and R(-) enantiomer, respectively), a lower apparent clearance (Cl/F) (32.8 ± 5.7 and 139.0 ± 25.1 mL/h·kg for the S(+) and R(-) enantiomer, respectively) and a lower apparent volume of distribution (V(d)/F) (139 ± 14.7 and 496 ± 139.4 mL/kg for the S(+) and R(-) enantiomer, respectively) were calculated for the S(+) enantiomer, indicating enantioselective pharmacokinetics for ketoprofen in calves following i.m. administration.

    1. The pharmacokinetics of doxycycline in ducks were investigated after a single intravenous (IV), intramuscular (IM) or oral (PO) dose at 20 mg/kg body weight. 2. The concentrations of doxycycline in plasma samples were assayed using a high performance liquid chromatography method, and pharmacokinetic parameters were calculated using a non-compartmental model. 3. After IV administration, doxycycline had a mean (±SD) distribution volume (Vz) of 1761.9 ± 328.5 ml/kg and was slowly eliminated with a terminal half-life (t₁/₂λz) of 21.21±1.47 h and a total body clearance (Cl) of 57.51 ± 9.50 ml/h/kg. Following PO and IM administration, doxycycline was relatively slowly absorbed - the peak concentrations (Cmax) were 17.57 ± 4.66 μg/ml at 2 h and 25.01 ± 4.18 μg/ml at 1.5 h, respectively. The absolute bioavailabilities (F) of doxycycline after PO and IM administration were 39.13% and 70.71%, respectively. 4. The plasma profile of doxycycline exhibited favourable pharmacokinetics characteristics in Muscovy ducks, such as wide distribution, relatively slow absorption and slow elimination, though oral bioavailability was low.

    Full Text Available Intramuscular fat (IMF deposition is a physiological process in cattle and is highly variable among breeds suggesting a large influence of genetic factors besides environmental factors. In order to elucidate molecular pathways underlying the genetic variation in this trait we compared transcriptomes of Musculus longissimus dorsi (MLD in steers of Japanese Black and Holstein Friesian cattle breeds fed a high energy diet typically applied in Japan to achieve maximum IMF content. We identified a total of 569 differentially expressed genes (DEGs with the majority (433 up-regulated in Japanese Black cattle. This breed is characterized by an extreme capacity for IMF deposition. Subsequent Ingenuity Pathway Analysis (IPA revealed a gene network linking parameters of cell morphology and maintenance with lipid metabolism. The data from this study were deposited in NCBI's Gene Expression Omnibus and are accessible through GEO Series accession number GSE75348. We provide here a dataset which is of potential value to dissect molecular pathways influencing differences in fat deposition under high-energy nutrition.

    Full Text Available The pharmacokinetics of diminazene aceturate following intramuscular (i.m. administration at 4.2 mg/kg was evaluated in 8 healthy German Shepherd dogs. Blood samples were collected at 19 intervals over a period of 21 days. Diminazene plasma concentrations were measured using a validated HPLC method with UV detection and a sensitivity of 25 ng/m . The in vitro and in vivo binding of diminazene to blood elements was additionally determined. Diminazene pharmacokinetics showed a large inter-individual variation after i.m. administration. It had a short absorption half-life (K01-HL of 0.11 + 0.18 h, resulting in a Cmax of 1849 + 268.7 ng/mℓ at Tmax of 0.37 h and a mean overall elimination half-life (T1/2ß of 5.31 + 3.89 h. A terminal half-life of 27.5 + 25.0 h was measured. At 1 h after i.m. injection, 75% of the diminazene in whole blood was in the plasma fraction. The results of this study indicate that diminazene is rapidly distributed and sequestered into the liver, followed by a slower terminal phase during which diminazene is both redistributed to the peripheral tissues and/or renally excreted. It is recommended that diminazene administered i.m. at 4.2 mg/kg should not be repeated within a 21-day period.

    Biocompatibility of layered double hydroxides (LDHs), also known as hydrotalcite-like materials or double metal hydroxides, was investigated by in vivo assays via intramuscular tablets implantation in rat abdominal wall. The tablets were composed by chloride ions intercalated into LDH of magnesium/aluminum (Mg2Al-Cl) and zinc/aluminum (Zn2Al-Cl). The antigenicity and tissue integration capacity of LDHs were assessed histologically after 7 and 28 days post-implantation. No fibrous capsule nearby the LDH was noticed for both materials as well any sign of inflammatory reactions. Sidestream Dark Field imaging, used to monitor in real time the microcirculation in tissues, revealed overall integrity of the microcirculatory network neighboring the tablets, with no blood flow obstruction, bleeding and/or increasing of leukocyte endothelial adhesion. After 28 days Mg2Al-Cl promoted multiple collagen invaginations (mostly collagen type-I) among its fragments while Zn2Al-Cl induced predominantly collagen type–III. This work supports previous results in the literature about LDHs compatibility with living matter, endorsing them as functional materials for biomedical applications. PMID:27480483

    Intramuscular adrenaline is the treatment of choice for food-related anaphylactic reactions. Although auto-injectable adrenaline devices are routinely prescribed for patients at risk of serious reactions, previous studies have shown that only one-third to one and a half of patients or their carers are able to properly use these devices. The aim of this study was to determine which factors are most strongly associated with the effective use of these devices. A 122 children with food allergies who had previously been prescribed EpiPens and were attending a single specialist pediatric allergy center in the UK. were studied prospectively. A 69% of parents were unable to use the EpiPen, did not have it available, or did not know when it should be administered. A prior practical demonstration was associated with a 4-5 fold greater chance that parents would be able to use the device (p EpiPens to be used safely and effectively it is essential to educate the carer at the time the device is prescribed.

    The passive properties of skeletal muscle are often overlooked in muscle studies, yet they play a key role in tissue function in vivo. Studies analyzing and modeling muscle passive properties, while not uncommon, have never investigated the role of fluid content within the tissue. Additionally, intramuscular pressure (IMP) has been shown to correlate with muscle force in vivo and could be used to predict muscle force in the clinic. In this study, a novel model of skeletal muscle was developed and validated to predict both muscle stress and IMP under passive conditions for the New Zealand White Rabbit tibialis anterior. This model is the first to include fluid content within the tissue and uses whole muscle geometry. A nonlinear optimization scheme was highly effective at fitting model stress output to experimental stress data (normalized mean square error or NMSE fit value of 0.993) and validation showed very good agreement to experimental data (NMSE fit values of 0.955 and 0.860 for IMP and stress, respectively). While future work to include muscle activation would broaden the physiological application of this model, the passive implementation could be used to guide surgeries where passive muscle is stretched.

    The aim of the study was to investigate the thickness of subcutaneous (SC) tissue in the dorsogluteal and thigh sites in obese adults and its suitability for intramuscular injection using a standard-length needle. The sample for this prospective study consisted of 54 obese adults who presented to the ultrasound unit of the radiology clinic of a university hospital in the province of İzmir, Turkey, between June 2012 and August 2013. The study received Institutional Review Board approval, and informed written consent was obtained from all participants. The thickness of the SC tissue in the dorsogluteal and thigh sites was measured by sonography. The sonographic measurements were performed by a radiology specialist. The mean thicknesses of the SC tissue were 61.70 ± 15.73 mm in the dorsogluteal site, 27.05 ± 8.52 mm in the rectus femoris site, and 23.23 ± 8.44 mm in vastus lateralis site. The SC tissue was thicker in the dorsogluteal than the thigh site (P njections to the thigh site would be effective in reaching the muscle in the rectus femoris and vastus lateralis sites in all men and in 77.8% of women, although it is not usually adequate for gluteal injection. © 2015 by the American Institute of Ultrasound in Medicine.

    The purpose of this study was to examine the interaction of a single dose of Toradol and head impact in an in vivo rat model for sport-related concussion using a validated rat concussion model. Thirty-five Sprague-Dawley rats were placed into one of four groups: (1) Control, (2) Impact Only, (3) Toradol Only, (4) Impact and Toradol. Animals in the impact groups were subjected to a single head impact. Animals in the Toradol group received a single intramuscular injection of Toradol prior to impact. We examined magnetic resonance imaging, serum S100-B and cognitive function using a Morris Water Maze. In the control group, latency decreased significantly from day 0 (74.9 s) to 24 h (57.4 s) after anesthesia. There was no statistically significant difference between time zero and 24 h after impact in the Impact only or Impact and Toradol group. Our findings indicate that there were no differences between cognitive ability, MRI findings or S100B in rats that were administered a single dose of Toradol and subjected to a single impact and rats that were subjected to a single impact only. In both impact groups there were transient changes in cognitive ability as measured by the Morris Water Maze.

    The purpose of this study was to investigate the pharmacokinetic characteristics of amoxicillin (AMX) trihydrate in male Asian elephants, Elephas maximus, following intramuscular administration at two dosages of 5.5 and 11 mg/kg body weight (b.w.). Blood samples were collected from 0.5 up to 72 h. The concentration of AMX in elephant plasma was measured using liquid chromatography electrospray ionization mass spectrometry. AMX was measurable up to 24 h after administration at two dosages. Peak plasma concentration (Cmax ) was 1.20 ± 0.39 μg/mL after i.m. administration at a dosage of 5.5 mg/kg b.w., whereas it was 3.40 ± 0.63 μg/mL at a dosage of 11 mg/kg b.w. A noncompartment model was developed to describe the disposition of AMX in Asian elephants. Based on the preliminary findings found in this research, the dosage of 5.5 and 11 mg/kg b.w. produced drug plasma concentrations higher than 0.25 mg/mL for 24 h after i.m. administration. Thereafter, i.m. administration with AMX at a dosage of 5.5 mg/kg b.w. appeared a more suitable dose than 11 mg/kg b.w. However, more studies are needed to determine AMX clinical effectiveness in elephants.

    A direct method for measuring force production of specific muscles during dynamic exercise is presently unavailable. Previous studies indicate that both intramuscular pressure (IMP) and electromyography (EMG) correlate linearly with muscle contraction force during isometric exercise. The objective of this study was to compare IMP and EMG as linear assessors of muscle contraction force during dynamic exercise. IMP and surface EMG activity were recorded during concentric and eccentric isokinetic plantarflexion and dorsiflexion of the ankle joint from the tibialis anterior (TA) and soleus (SOL) muscles of nine male volunteers. Ankle torque was measured using a dynamometer, and IMP was measured via catheterization. IMP exhibited better linear correlation than EMG with ankle joint torque during concentric contractions of the SOL and the TA, as well as during eccentric contractions. IMP provides a better index of muscle contraction force than EMG during concentric and eccentric exercise through the entire range of torque. IMP reflects intrinsic mechanical properties of individual muscles, such as length-tension relationships, which EMG is unable to assess.

    Full Text Available Physical castration (PC is painful and stressful for nursing piglets. One alternative to PC is immunological castration (IC, but the pain and stress of handling associated with injections have not been assessed. The objectives of this study were to measure the pain and distress of subcutaneous (SQ and intramuscular (IM injections compared to PC in piglets, and to compare SQ or IM injections in finishing pigs. After farrowing, 3 to 5 d old male piglets were randomly assigned to (control no handling treatment (NO, sham-handling (SHAM, IM, SQ, or PC. Finishing pigs were assigned to NO, SHAM, IM, or SQ. Behavior was monitored for 1 h prior and 1 h post treatment in each age group. Social, feeding behaviors, and signs of pain were recorded. Finishing pigs treated with SQ injections had higher feeding behaviors pre-treatment than they did post-treatment. Overall, physical castrations caused measurable pain-like behaviors and general behavioral dysregulation at a much higher level than the other treatment groups. SQ and IM injections did not cause either significant behavioral or physiological alterations in piglets. SQ injections caused a decrease in finishing pig feed behaviors post treatment ( p = 0.02 and SHAM treated finishing pigs spent significantly more time lying than the other treatment groups. In general IM and SQ injections did not cause any other significant changes in behavior or physiology.

    The thermal property of bovine intramuscular adipose tissue (IAT) was evaluated using differential scanning calorimetry (DSC) and compared with the melting point temperature (MP) of the fat extract of IAT, which was measured using the slip point method. The beef samples were classified according to the beef marbling score (BMS). Beef with a high BMS contained less protein than that with middle or low BMS. Beef with a high BMS contained significantly more fat than that with a low BMS (P < 0.05). The endothermic point temperature (EP) of IAT, measured by DSC, was significantly higher than the MP of IAT fat (P < 0.05). The EP showed no significant difference among the three marbling grade groups. Although the MP was correlated with the monounsaturated fatty acids (MUFA) content of IAT (R(2)  = 0.505), there was no correlation between the EP and the MUFA (R(2)  = 0.040). However, the EP of IAT treated with collagenase was relatively highly correlated with the MP (R(2)  = 0.655). Thus, these results suggested that DSC analysis would give us the practical thermal information regarding the melt-in the-mouth of beef such as the gelatinization of collagen, along with the melting of fat in IAT. © 2017 The Authors.

    The disposition kinetics of marbofloxacin, a fluoroquinolone antibiotic, after intravenous (i.v.), intramuscular (i.m.) and subcutaneous (s.c.) administration was determined in rabbits at a single dose of 2 mg/kg. Plasma concentrations of marbofloxacin were determined by high performance liquid chromatography with fluorescence detection. The concentration-time data were analysed by compartmental and non-compartmental pharmacokinetic methods. Steady-state volume of distribution (V(ss)) and clearance (Cl) of marbofloxacin after i.v. administration were 1.99±0.27 L/kg and 0.42±0.04 L/h kg, respectively. Following i.m. and s.c. administration marbofloxacin achieved maximum plasma concentrations of 2.04±0.32 and 1.64±0.15 mg/L at 0.33±0.16 and 0.50±0.18 h, respectively. The absolute bioavailabilities after i.m. and s.c. routes were 123.30±17.64% and 114.81±12.11%, respectively. From these data (kinetic parameters and absence of adverse reactions) marbofloxacin is likely to be effective in rabbits.

    Pharmacokinetic (PK) parameters of marbofloxacin (MRFX) in Korean cattle, Hanwoo, were determined following its intravenous (i.v.) or intramuscular (i.m.) administration at a dose of 2 mg/kg. Area under the curve (AUC0-24 hr), half-life (t1/2) and total body clearance (CLB) of i.v. MRFX were 6.87 hr∙µg/ml, 2.44 hr and 0.29 l/kg∙hr, respectively, and the corresponding values for i.m. administration of MRFX were 5.07 hr∙µg/ml, 2.44 hr and 0.39 l/kg∙hr. The suggested optimal doses of MRFX in Hanwoo cattle, calculated by integration of PK data obtained in the present study and previously reported minimum inhibitory concentration (MIC) for MRFX against susceptible (MIC ≤1 µg/ml) and intermediate (MIC ≤2 µg/ml) pathogenic bacteria, were 2.1 and 4.2 mg/kg/day by i.v. route and 3.9 and 7.8 mg/kg/day by i.m. route.

    Patients with chronic exertional compartment syndrome (CECS) have pain during exercise that subsides with rest. Diagnosis is usually confirmed by intramuscular compartment pressure (IMCP) measurement. Controversy exists regarding the accuracy of existing diagnostic criteria. (1) To compare dynamic IMCP measurement and anthropometric factors between patients with CECS and asymptomatic controls and (2) to establish the diagnostic utility of dynamic IMCP measurement. Cohort study (diagnosis); Level of evidence, 2. A total of 40 men aged 21 to 40 years were included in the study: 20 with symptoms of CECS of the anterior compartment and 20 asymptomatic controls. Diagnoses other than CECS were excluded with rigorous inclusion criteria and magnetic resonance imaging. The IMCP was measured continuously before, during, and after participants exercised on a treadmill, wearing identical footwear and carrying a 15-kg load. Pain experienced by study subjects increased incrementally as the study progressed (P compartment IMCP is elevated immediately upon standing at rest in subjects with CECS. In patients with symptoms consistent with CECS, diagnostic utility of IMCP measurement is improved when measured continuously during exercise. A cutoff of 105 mm Hg in phase 2 provides better diagnostic accuracy than do the Pedowitz criteria of 30 mm Hg and 20 mm Hg at 1 and 5 minutes after exercise, respectively. © 2014 The Author(s).

    The purpose of this study was to assess relationships between intramuscular adipose tissue (IntraMAT) content determined by MRI and intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL) determined by (1)H magnetic resonance spectroscopy ((1)H MRS) or echo intensity determined by B-mode ultrasonography of human skeletal muscles. Thirty young and elderly men and women were included. T1-weighted MRI was taken from the right mid-thigh to measure IntraMAT content of the vastus lateralis (VL) and biceps femoris (BF) using a histogram shape-based thresholding technique. IMCL and EMCL were measured from the VL and BF at the right mid-thigh using (1)H MRS. Ultrasonographic images were taken from the VL and BF of the right mid-thigh to measure echo intensity based on gray-scale level for quantitative analysis. There was a significant correlation between IntraMAT content by MRI and EMCL of the VL and BF (VL, r=0.506, Plipids, not intramyocellular lipids, in human skeletal muscles.

    Full Text Available Little is known about the fatty acid composition of the major muscles in goats from different breeds. Forty entire male suckling kids, 20 Criollo Cordobes and 20 Anglo Nubian, were slaughtered at 75 days of age and the fatty acid composition of their longissimus thoracis (LT and semitendinosus (ST muscles was analysed to clarify the effects of genotype and muscle type on goat kid meat. Genotype had a great influence on the fatty acid composition of goat kid meat. Meat from Criollo Cordobes had greater saturated (P<0.001 and lower monounsaturated (P<0.001 and polyunsaturated fatty acids (P=0.002 concentration than meat from Anglo Nubian, showing higher saturated fatty acids (SFA. On the other hand, intramuscular fat content from both genotypes was higher (P=0.042 in ST muscle, while the lowest cholesterol levels were observed in ST of Criollo Cordobes (P=0.038. That higher fat content resulted in lower relative contents of total polyunsaturated (P<0.001 and n-3 (P=0.002 fatty acids due to the lower contribution of the membrane phospholipids.

    Our goal was to assess the toxicity of two strengths (200 and 400 μg) of HER1 cancer vaccine (Center of Molecular Immunology, Cuba), presented in two different formulations, in Sprague Dawley rats after repeated intramuscular administration (14 days). Four groups (5 animals/sex) were established: Control, Placebo (adjuvant), and two Treated groups receiving a dose representing ten times of human total dose (10×), 28.6 and 57.1 μg/kg. Clinical observations, body weight and rectal temperature were measured during the study. Clinical pathology analysis was performed, besides gross necropsy and histological examination of tissues on animals at the end of the assay. The assay ended with a 100% survival. Injection site damage, with the presence of cysts and granulomas, was observed in adjuvant and vaccine treated groups, with most severe cases predominating at higher strength. Administration of Placebo and Her1 vaccine induced increase in polymorphonuclear cells, with relative lymphopenia conditioned by primary neutrophilia. In summary, results suggest that Her1 immunization was capable of inducing an inflammatory effect at the injection site, leading to systemic alterations, more significant at higher strength (400 μg, 57.1 μg/kg), probably affected by the immunizations' schedule used. The vaccine was shown to be well tolerated without any obvious signs of systemic toxicity, with findings largely attributable to the adjuvant used.

    Fat infiltration within skeletal muscle is known as intramuscular fat (IMF), which increases with aging. Studies have assessed IMF content, using the mid-thigh as a representative location. However, three-dimensional IMF distribution is not well understood. The aim of this study was to compare the IMF content in young and old adults by assessing its distribution along the length of the thigh. Consecutive transaxial images of the right thighs in 15 young (age, 21.0 ± 0.4) and 15 old (age, 70.7 ± 3.8) were obtained by magnetic resonance imaging. We measured IMF cross-sectional area (CSA), skeletal muscle CSA and calculated volume- and CSA-based IMF content for the quadriceps femoris (QF), hamstring (HM) and adductor (AD). CSA-based calculations were performed at every 10% of femur length (Lf), with 0% Lf and 100% Lf indicating the proximal and distal ends of femur. IMF CSAs along the length of the thigh were similar in both age groups. In contrast, skeletal muscle CSAs in all three muscle groups were significantly lower in old adults than in young adults (variation: -15.2 to -1.6 cm(2), P increase in IMF content-confirmed in areas of the thigh-primarily based on finding lower amounts of skeletal muscle mass in CSAs in the older adults.

    Selection for lean growth through Australian Sheep Breeding Values (ASBVs) for post weaning weight (PWWT), eye muscle depth (PEMD) and c-site fat depth (PFAT) raises concerns regarding declining intramuscular fat (IMF) levels. Reducing PFAT decreased IMF by 0.84% for Terminal sired lambs. PEMD decreased IMF by 0.18% across all sire types. Female lambs had higher IMF levels and this was unexplained by total carcass fatness. The negative phenotypic association between measures of muscling (shortloin muscle weight, eye muscle area) and IMF, and positive association between fatness and IMF, was consistent with other literature. Hot carcass weight increased IMF by 2.08% between 12 and 40 kg, reflective of development of IMF as lambs approach maturity. Selection objectives with low PFAT sires will reduce IMF, however the lower impact of PEMD and absence of a PWWT effect, will enable continued selection for lean growth without influencing IMF. Alternatively, the negative impact of PFAT could be off-set by inclusion of an IMF ASBV. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

    This study aimed to construct DNA vaccines encoding the mouse P1A tumor antigen and to generate a protective immune response against the P815 mastocytoma, as a model for vaccines against human MAGE-type tumor antigens. DNA vaccines were constructed and delivered to mice by intramuscular electroporation before tumor challenge. Immunization with a plasmid coding for the full-length P1A significantly delayed tumor growth and mice survived at least 10 days longer than untreated controls. 10% of the mice completely rejected the P815 tumors while 50% of them showed a regression phase followed by tumor regrowth. Mice immunized by electroporation of a P1A(35-43) minigene-encoding plasmid failed to reject tumor and even delay tumor growth. The P1A(35-43)-encoding plasmid was modified and helper epitope sequences were inserted. However, these modified plasmids were not able to improve the response against P815 mastocytoma. Consistent with these results, a 12-fold higher CTL activity was observed when the plasmid coding for full-length P1A was delivered as compared to the plasmid encoding the P1A(35-43) epitope. Our results demonstrated that electroporation is an efficient method to deliver DNA vaccines against P815 and suggested the superiority of full-length as compared to minigene constructs for DNA vaccines.

    Previous electromyographic (EMG) studies of gluteus medius (GMed) have not accurately quantified the function of the three proposed structurally and functionally unique segments (anterior, middle and posterior). Therefore this study used anatomically verified locations for intramuscular electrode recordings in three segments of GMed to determine whether the segments are functionally independent. Bipolar fine wire electrodes were inserted into each segment of GMed in 15 healthy individuals. Participants completed a series of four walking trials, followed by maximum voluntary isometric contractions (MVICs) in five different positions. Temporal and amplitude variables for each segment were compared across the gait cycle using ANOVA. The relative contributions of each segment to the MVIC trials were compared with non-parametric tests. All segments showed a biphasic response during the stance phase of gait. There were no differences in amplitude variables (% MVIC) between segments, but the anterior segment had a later peak during both the first and second bursts.For the MVIC trials, there were significant differences in amplitude between segments in four of the five test positions. These data indicate that GMed is composed of three functionally independent segments. This study contributes to the theoretical understanding of the role of GMed.

    Keratocystic odontogenic tumor (KCOT), a developmental jaw cyst previously referred to as odontogenic keratocyst (OKC), typically arises in the jawbone. In this article, however, we report a case of KCOT located within the temporalis muscle. We compared its immunohistochemical profiles with those of authentic jaw KCOT, orthokeratinized odontogenic cyst, and epidermoid cyst in order to consider whether a soft tissue counterpart of KCOT could be a separate disease entity. The patient was a 46-year-old man with a well-defined cystic lesion within the left temporalis muscle. On computed tomographic images, the lesion was recognized as a cystic lesion, although KCOT was not included in the clinical differential diagnoses. The location of the lesion was not within bone but, rather, within the temporalis muscle that was attached to the jawbones. Our review of the literature has disclosed more than 20 peripheral KCOT cases of the oral mucosa and more than 10 cases of the skin, but only 1 case arising in muscle. Immunohistochemical investigation of the present intramuscular case reveals KCOT-characteristic profiles distinct from the other 3 types of cysts investigated. The results indicate that KCOT-like lesions can arise within soft tissues, although use of the term odontogenic might seem inappropriate in those cases.

    Restoring dexterous motor function equivalent to that of the human hand after amputation is one of the major goals in rehabilitation engineering. To achieve this requires the implementation of a effortless human-machine interface that bridges the artificial hand to the sources of volition. Attempts to tap into the neural signals and to use them as control inputs for neuroprostheses range in invasiveness and hierarchical location in the neuromuscular system. Nevertheless today, the primary clinically viable control technique is the electromyogram measured peripherally by surface electrodes. This approach is neither physiologically appropriate nor dexterous because arbitrary finger movements or hand postures cannot be obtained. Here we demonstrate the feasibility of achieving real-time, continuous and simultaneous control of a multi-digit prosthesis directly from forearm muscles signals using intramuscular electrodes on healthy subjects. Subjects contracted physiologically appropriate muscles to control four degrees of freedom of the fingers of a physical robotic hand independently. Subjects described the control as intuitive and showed the ability to drive the hand into 12 postures without explicit training. This is the first study in which peripheral neural correlates were processed in real-time and used to control multiple digits of a physical hand simultaneously in an intuitive and direct way.

    Obese sheep were used to assess the effects of palmitoleic (C16:1 cis-9) acid infusion on lipogenesis and circulating insulin levels. Infusion of 10 mg/kg body weight (BW)/day C16:1 intravenously in obese sheep reduced (Psubcutaneous adipose tissue was not altered. Total lipid content of the liver was also unchanged with C16:1 infusion. Palmitoleic acid infusion upregulated (Psubcutaneous adipose, and ST muscle compared to the controls. However, mRNA expression of glucose transporter type 4 (GLUT4) and carnitine palmitoyltransferase 1b (CPT1B) differed between tissues. In the subcutaneous adipose and liver, C16:1 infusion upregulated (P<0.05) GLUT4 and CPT1B, whereas these genes were downregulated (P<0.05) in ST muscle with C16:1 infusion. These results show that C16:1 infusion for 28 days reduced weight gain, intramuscular adipocyte size and total lipid content, and circulating insulin levels. These changes appear to be mediated through alterations in expression of genes regulating glucose uptake and fatty acid oxidation specifically in the muscles.

    The lethal toxicity of inorganic (HgCl2) and organic (CH3HgCl) mercury chloride was compared for Coturnix (Japanese quail, Coturnix japonica) of different ages from hatch through adulthood by single-dose acute oral and intramuscular injections and by a 5-d dietary trial. Sublethal mercury toxicity was studied by evaluation of plasma and brain cholinesterase activity. CH3HgCl was more toxic than HgCl2 in all tests at each age tested. LD50s consistently increased over the first 4 wk for both acute methods and both mercurials and then stabilized. The striking difference between single-dose acute and 5-d dietary tests was that CH3HgCl averaged about twice as toxic as HgCl2 by both acute methods, compared to 100 times as toxic by the dietary method. For example, at 2 wk of age, the oral LD50s for CH3HgCl and HgCl2 were 18 and 42 mg/kg and the dietary LC50s were 47 and 5086 ppm. When birds were fed HgCl2 and developed clinical signs of intoxication, they could recover once treatment was withdrawn; however, on CH3HgCl, clinical signs often commenced after treatment was withdrawn, and then actually intensified for several days and culminated in death.

    Full Text Available OBJECTIVE A genuine attempt was made to find ideal drug for premedication in paediatric surgical patients. Dexmedetomidine a newer, highly selective alpha-2 agonist was compared to midazolam via intramuscular route. Setting: Institute-Department of Anaesthesiology, Krishna Institute of Medical Sciences. METHODS Dexmedetomidine group (Group D with the conventional Midazolam group (Group M was compared for premedication in cases of paediatric surgical patients. A total of sixty patients, scheduled for elective surgery of duration 15 to 90 minutes, were enrolled and randomly assigned in a double blind manner to Group D and Group M. Intramuscular Dexmedetomidine (1.5 mcg/kg in Group D or midazolam (0.05 mg/kg in Group M, as a premedication in preoperative room was given and sedation score with Ramsay sedation scale and parent separation anxiety score were recorded. After 45 mins, patient was shifted in the operation room and a standard technique of anaesthesia was applied to all patients. Mask acceptance score, wake up score, demand of post-op analgesia, time for first analgesia requirement were recorded. RESULTS Our study comparing dexmedetomidine with midazolam premedication found a stable heart rate and blood pressure with comparable sedative effects, (90% vs 56%, P value 0.0074 concluded that dexmedetomidine group had better sedative effect. Parent separation anxiety score was better with dexmedetomidine group compared to midazolam group with p value 0.0419 (93% vs 70%. Mask acceptance was better with dexmedetomidine group compared to midazolam group with p value 0.0153 (90% vs 60%. Wake up score were compared and dexmedetomidine was better than midazolam with p value 0.0001 (93% vs 46%. CONCLUSION Premedication with low-dose intramuscular dexmedetomidine resulted in better sedation, lower anxiety levels during parent separation, better mask acceptance and wake up behaviour as compared with low-dose intramuscular midazolam.

    Background and Objectives Vitamin D deficiency is frequent during the winter and occurs throughout the year in the elderly or patients suffering from autoimmune diseases. The objective of this study was to evaluate the pharmacokinetic properties of oral supplementation versus a single intramuscular injection of cholecalciferol in healthy individuals. Research design and methods Up to 8,000 I.U. oral cholecalciferol was administered daily for 84 days in a 4 week dose-escalation setting to vitamin D deficient individuals. In another cohort, a single intramuscular injection of 100,000 I.U. cholecalciferol was given. In both cohorts, individuals without vitamin D intake served as the comparison group. 25-hydroxyvitamin D (25(OH)D) concentrations were measured in all individuals at defined time points throughout the studies. Results The mean 25(OH)D serum concentration increased significantly after oral cholecalciferol intake compared to the control group (day 28: 83.4 nmol/l and 42.5 nmol/l; day 56: 127.4 nmol/l and 37.3 nmol/l; day 84: 159.7 nmol/l and 30.0 nmol/l). In individuals receiving 100,000 I.U. cholecalciferol intramuscular, the mean 25(OH)D serum concentration peaked after 4 weeks measuring 70.9 nmol/l compared to 32.7 nmol/l in the placebo group (p = 0.002). The increase of 25(OH)D serum concentrations after 28 days was comparable between both routes of administration (p = 0.264). Conclusions Oral and intramuscular cholecalciferol supplementation effectively increased serum 25(OH)D concentrations. PMID:28114352

    Full Text Available CONTEXT AND OBJECTIVE: Dipyrone is a widely used over-the-counter antipyretic in Latin America, and elsewhere among Latin immigrants. Despite limited evidence, physicians often prescribe oral ibuprofen or intramuscular dipyrone as the most effective antipyretics. Our aim was to compare the antipyretic efficacy and tolerability of a single dose of oral ibuprofen, oral dipyrone or intramuscular dipyrone in febrile children. DESIGN AND SETTING: Randomized, single-blind clinical trial, at San Bartolomé Mother-Child National Teaching Hospital, Lima, Peru. METHODS: Children from six months to six years old with fever (rectal temperature: 38.3 to 39.8° C in the emergency ward between February and June 2003 were eligible. Seventy-five children were randomly assigned to receive a single dose of oral ibuprofen (10 mg/kg, oral dipyrone (15 mg/kg or intramuscular dipyrone (15 mg/kg. The primary outcome was mean temperature reduction after 30, 45, 60, 90 and 120 minutes. Secondary outcomes were fever-associated symptoms and clinical adverse events. RESULTS: Fever decreased by about 0.5° C after 45 minutes and by about 1.0° C after 120 minutes in all three groups. Mean temperatures were similar for the three groups at all times. There was a significant decrease in fever-associated symptoms for all groups. Six patients (four receiving oral dipyrone and two receiving ibuprofen were withdrawn because of vomiting within 20 minutes after first dose of study medication. One patient assigned to oral ibuprofen presented transient urticaria. CONCLUSIONS: Antipyretic efficacy and tolerability were similar for oral ibuprofen, oral dipyrone and intramuscular dipyrone. Oral antipyretics seem more appropriate for feverish children.

    Estrogen (E2 )-responsive peripheral tissues, such as skeletal muscle, may suffer from hormone deficiency after menopause potentially contributing to the aging of muscle. However, recently E2 was shown to be synthesized by muscle and its systemic and intramuscular hormone levels are unequal. The objective of the study was to examine the association between intramuscular steroid hormones and muscle characteristics in premenopausal women (n = 8) and in postmenopausal monozygotic twin sister pairs (n = 16 co-twins from eight pairs) discordant for the use of E2 -based hormone replacement. Isometric skeletal muscle strength was assessed by measuring knee extension strength. Explosive lower body muscle power was assessed as vertical jump height. Due to sequential nature of enzymatic conversion of biologically inactive dehydroepiandrosterone (DHEA) to testosterone (T) and subsequently to E2 or dihydrotestosterone (DHT), separate linear regression models were used to estimate the association of each hormone with muscle characteristics. Intramuscular E2 , T, DHT, and DHEA proved to be significant, independent predictors of strength and power explaining 59-64% of the variation in knee extension strength and 80-83% of the variation of vertical jumping height in women (P strength and power regulation in female muscle providing novel insight to the field of muscle aging.

    BACKGROUND: Combined hepatitis B immune globulin (HBIg) and lamivudine in prophylaxis of the recurrence of hepatitis B after liver transplantation has signiifcantly improved the survival of HBsAg positive patients. This study was undertaken to evaluate the outcomes of liver transplantation for patients with hepatitis B virus (HBV). METHODS: A retrospective chart analysis and a review of the organ transplant database identiifed 51 patients (43 men and 8 women) transplanted for benign HBV-related cirrhotic diseases between June 2002 and December 2004 who had survived more than 3 months. HBIg was administered intravenously during the ifrst week and intramuscularly thereafter. RESULTS: At a median follow-up of 14.1 months, the overall recurrence rate in the 51 patients was 3.9%(2/51). The overall patient survival was 88.3%, and 82.4%after 1 and 2 years, respectively. A daily oral dose of 100 mg lamivudine for 2 weeks before transplantation for 10 patients enabled 57.1%(4/7) and 62.5%(5/8) of HBV-DNA and HBeAg positive patients respectively to convert to be negative. Intramuscular HBIg was well tolerated in all patients. CONCLUSION:Lamivudine combined with intramuscular HBIg can effectively prevent allograft from the recurrence of HBV after liver transplantation.

    Misoprostol is an effective agent for the induction of labor. Existing guidelines recommend oral misoprostol solution 25 μg every 2 hours. However, more research is required to optimize the use of oral misoprostol solution for the induction of labor. The purpose of this study was to compare efficacy and safety of hourly titrated-dose oral misoprostol solution with static-dose oral misoprostol solution every 2 hours for labor induction. In this randomized controlled study, oral misoprostol solution was administered as (1) 20 μg hourly (≤4 doses) that was increased in the absence of regular uterine contractions to 40 μg hourly (≤4 doses) and then to 60 μg hourly (≤16 doses) or (2) 25 μg every 2 hours until active labor began (≤12 doses). A sample size of 146 women was planned with the use of a projected 95% rate for the primary endpoint (vaginal delivery within 24 hours) for hourly titrated-dose misoprostol and 80% rate for static-dose misoprostol every 2 hours. Safety outcomes included maternal morbidity and adverse neonatal outcomes. From December 2013 to July 2015, 146 women were assigned randomly to treatment. Demographic and clinical factors were similar between groups, except for age. Vaginal delivery was achieved within 24 hours in 47 women (64.4%) who received hourly titrated-doses of misoprostol solution and 48 women (65.8%) who received 2-hourly static-dose misoprostol solution (P=1.00). Rates of vaginal delivery within 24 hours did not differ significantly between treatment groups for women who were nulliparous (P=1.00) or who had postterm pregnancies (P=.66), a Bishop score of ≤3 (P=.84), or oxytocin augmentation (P=.83). Cesarean deliveries were performed within 24 hours in 9 women who received hourly titrated-dose misoprostol solution and 2 women who received 2-hourly static-dose misoprostol solution (P=.056). Pyrexia and meconium-stained liquor occurred more frequently with the hourly titrated-dose regimen. The static-dose oral

    Elevated intraocular pressure (IOP) is a clinically relevant factor in glaucoma progression. As a dynamic parameter the IOP depends on various internal and exogenic influencing factors. Therefore, we analysed intraindividual IOD variations between ambulant care and 24-h home-monitoring using self-tonometry. This study is based on paper-based glaucoma cards of 25 patients with primary open angle glaucoma. Additionally, all patients participated in a telemedical home-monitoring study with self-measurements of IOP and blood pressure stored in an electronic patient record. The glaucoma cards contained a total number of 409 IOP values with documentation periods from 0.5 to 10 years. In the teletonometry project all 25 patients were observed for 6 months with 1490 recorded IOP values. Statistical analysis was performed with SPSS software. Average IOP values for all 25 glaucoma patients were 16.3 +/- 2.9 mmHg for both eyes in glaucoma card documentation, whereas the electronic patient records showed IOP averages of 18.9 +/- 4.7 mmHg for right eyes and 18.2 +/- 4.4 mmHg for left eyes. Corresponding to the practice opening hours the glaucoma cards contained no IOP records from 12:00 pm to 01:30 pm as well as between 06:00 pm and 07:15 am. In these time periods 17 % of all IOP values recorded in 24-hour teletonometry were higher than 20 mmHg. However, statistical analysis and clinical evaluation of device parameters and measurement characteristics revealed sporadic measuring errors. The additional involvement of self-tonometry in telemedical 24-h home-monitoring is a feasible method to record and detect intraday IOP fluctuations. Compared to single IOP measurements documented in common paper-based glaucoma cards, the 24-h electronic patient record showed more frequent circadian IOP variations. As a result, self-tonometry and home-monitoring can be a useful link to fill the gap between singular ambulant IOP measurement and hospitalisation with 24-hour IOP profiles.

    Full Text Available This paper will discuss the aspects of content schemata in second language reading among diploma level students who were taking a reading course in Universiti Teknologi MARA Perlis. In this qualitative case study, the researcher had selected two short stories that are categorized as content-familiar texts, i.e. The Hunted Fox and Twelve and Not Stupid. Six participants were asked to write a 150-word entry response on the short story and a grading criteria was used to assess the participants’ level of comprehension. An in-depth interview was also conducted on each participant. The entry responses and the interview patterns were analyzed to determine whether content schemata had contributed to the learners’ understanding of the text. This study discovered that content schemata had contributed to the learners’ understanding of the text because the learners’ comprehension was facilitated by their background knowledge on the content-familiar texts.

    The genus Porphyra (and its sister genus Pyropia) contains important red algal species that are cultivated and/or harvested for human consumption, sustaining a billion-dollar aquaculture industry. A vast amount of research has been focused on species of this genus, including studies on genetics and genomics among other areas. Twelve novel microsatellite markers were developed here for Porphyra linearis. Markers were characterized using 32 individuals collected from four natural populations of P. linearis with total heterozygosity varying from 0.098 to 0.916. The number of alleles per locus ranged from 2 to 18. All markers showed cross amplification with Porphyra umbilicalis and/or Porphyra dioica. These polymorphic microsatellite markers are useful for investigating population genetic diversity and differentiation in P. linearis and may become useful for other genetic research on the reproductive biology of this important species.

    Human milk is a rich source of bioactive proteins that support the early growth and development of the newborn. Although the major components of the protein fraction in human milk have been studied, the expression and relative abundance of minor components have received limited attention. We examined the expression of low-abundance proteins in the whey fraction of human milk and their dynamic changes over a twelve-month lactation period. The low-abundance proteins were enriched by ProteoMiner beads, and protein identification was performed by liquid chromatography tandem mass spectrometry. One hundred and fifteen proteins were identified, thirty-eight of which have not been previously reported in human colostrum or milk. We also for the first time described differences in protein patterns among the low-abundance proteins during lactation. These results enhance our knowledge about the complexity of the human milk proteome, which constitutes part of the advantages to the breast-fed infant.

    Massive open online courses (MOOCs) are a novel mode of online learning. They are typically based on higher education courses and can attract a high number of learners, often in the thousands. They are distinct from on-campus education and deliver the learning objectives through a series of short videos, recommended readings and discussion fora, alongside automated assessments. Within medical education the role of MOOCs remains unclear, with recent proposals including continuing professional development, interprofessional education or integration into campus-based blended learning curricula. In this twelve tips article, we aim to provide a framework for readers to use when developing, delivering and evaluating a MOOC within medical education based on the literature and our own experience. Practical advice is provided on how to design the appropriate curriculum, engage with learners on the platform, select suitable assessments, and comprehensively evaluate the impact of your course.

    Twelve novel 7'-hydroxy lignan glucosides (1-12), including two benzofuran-type neolignans, two 8-O-4' neolignans, two dibenzylbutyrolactone lignans, and six tetrahydrofuranoid lignans, together with six known lignan glucosides (13-18), were isolated from the fruit of Arctium lappa L. (Asteraceae), commonly known as Arctii Fructus. Their structures were elucidated using spectroscopy (1D and 2D NMR, MS, IR, ORD, and UV) and on the basis of chemical evidence. The absolute configurations of compounds 1-12 were confirmed using rotating frame nuclear overhauser effect spectroscopy (ROESY), the circular dichroic (CD) exciton chirality method, and Rh2(OCOCF3)4-induced CD spectrum analysis. All of the isolated compounds were tested for hepatoprotective effects against D-galactosamine-induced cytotoxicity in HL-7702 hepatic cells. Compounds 1, 2, 7-12, and 17 showed significantly stronger hepatoprotective activity than the positive control bicyclol at a concentration of 1 × 10(-5) M.

    Review of studies published in medical education journals over the last decade reveals that teaching medical professionalism is essential, yet challenging. According to a recent Best Evidence in Medical Education (BEME) guide, there is no consensus on a theoretical or practical model to integrate the teaching of professionalism into medical education. The aim of this article is to outline a practical manual for teaching professionalism at all levels of medical education. Drawing from research literature and author's experience, Twelve Tips are listed and organised in four clusters with relevance to (1) the context, (2) the teachers, (3) the curriculum, and (4) the networking. With a better understanding of the guiding educational principles for teaching medical professionalism, medical educators will be able to teach one of the most challenging constructs in medical education.

    Ambulance diversion is a problem in many communities. When patients are diverted prompt and appropriate medical care may be delayed. Compare diversion hours and drop-off times before and after a dramatic change in diversion policy restricting each hospital to 1 hour out of every 8. This study was a retrospective study in a county of 600,000 people and 10 hospitals from September 2004 to February 2006. A countywide diversion protocol was implemented in March 2005 that limited diversion hours to 1 hour out of every 8 (maximum of 90 h/mo). No other changes were implemented during the study period. Pretrial (9/04-2/05), interim (3/05-8/05), and posttrial (9/05-2/06) periods were compared. The main outcome measures were ambulance diversion hours and emergency medical service (EMS) drop-off times. Results were compared using analysis of variance and a Tukey post hoc analysis. P ambulance diversion hours (difference, 251 hours; 95% CI, 136-368) and significant increase in additional time that EMS crews required to transport patients (drop-off times) (difference, 178 hours; 95% CI, 74-283) were observed. Posttrial diversion hours decreased to 18% of the pretrial values (from 305 to 54). This novel ambulance diversion protocol dramatically reduced diversion hours at the cost of increasing EMS drop-off times in a large community.

    Full Text Available Abstract Background M. catarrhalis is a gram-negative, gamma-proteobacterium and an opportunistic human pathogen associated with otitis media (OM and exacerbations of chronic obstructive pulmonary disease (COPD. With direct and indirect costs for treating these conditions annually exceeding $33 billion in the United States alone, and nearly ubiquitous resistance to beta-lactam antibiotics among M. catarrhalis clinical isolates, a greater understanding of this pathogen's genome and its variability among isolates is needed. Results The genomic sequences of ten geographically and phenotypically diverse clinical isolates of M. catarrhalis were determined and analyzed together with two publicly available genomes. These twelve genomes were subjected to detailed comparative and predictive analyses aimed at characterizing the supragenome and understanding the metabolic and pathogenic potential of this species. A total of 2383 gene clusters were identified, of which 1755 are core with the remaining 628 clusters unevenly distributed among the twelve isolates. These findings are consistent with the distributed genome hypothesis (DGH, which posits that the species genome possesses a far greater number of genes than any single isolate. Multiple and pair-wise whole genome alignments highlight limited chromosomal re-arrangement. Conclusions M. catarrhalis gene content and chromosomal organization data, although supportive of the DGH, show modest overall genic diversity. These findings are in stark contrast with the reported heterogeneity of the species as a whole, as wells as to other bacterial pathogens mediating OM and COPD, providing important insight into M. catarrhalis pathogenesis that will aid in the development of novel therapeutic regimens.

    Developing an effective anthrax vaccine that can induce a rapid and sustained immune response is a priority for the prevention of bioterrorism-associated anthrax infection. Here, we developed a recombinant replication-deficient adenovirus serotype 5-based vaccine expressing the humanized protective antigen (Ad5-PAopt). A single intramuscular injection of Ad5-PAopt resulted in rapid and robust humoral and cellular immune responses in Fisher 344 rats. Animals intramuscularly inoculated with a single dose of 10⁸ infectious units of Ad5-PAopt achieved 100% protection from challenge with 10 times the 50% lethal dose (LD₅₀) of anthrax lethal toxin 7 days after vaccination. Although preexisting intranasally induced immunity to Ad5 slightly weakened the humoral and cellular immune responses to Ad5-PAopt via intramuscular inoculation, 100% protection was achieved 15 days after vaccination in Fisher 344 rats. The protective efficacy conferred by intramuscular vaccination in the presence of preexisting intranasally induced immunity was significantly better than that of intranasal delivery of Ad5-PAopt and intramuscular injection with recombinant PA and aluminum adjuvant without preexisting immunity. As natural Ad5 infection often occurs via the mucosal route, the work here largely illuminates that intramuscular inoculation with Ad5-PAopt can overcome the negative effects of immunity induced by prior adenovirus infection and represents an efficient approach for protecting against emerging anthrax.

    This study investigates the determinants of long working hours from the perspectives of the demand-control model [Karasek, 1979] and social exchange theory [Blau, 1964; Goulder, 1960]. These two theoretical perspectives are tested to understand why individuals work longer (or shorter) hours. The hypotheses are tested with a representative sample of 1,604 employed Canadians. In line with Karasek's model, the results support that high job demands are positively associated with longer work hours. The social exchange perspective would predict a positive association between skill discretion and work hours. This hypothesis was supported for individuals with a higher education degree. Finally, the results support a positive association between active jobs and longer work hours. Our research suggests that job demands and social exchange dynamics need to be considered together in the explanation of longer (or shorter) work hours.

Using PISA scores of students in ninth grade, we analyse the effect of a German education reform that increased weekly instruction hours by two hours (6.5 percent) overalmost five years. In the additional time, students are taught new learning content. On average, the reform improves student performance. However, treatment effects are small and differ across the student performance distribution. While low-performing stude...

    Full Text Available OBJECTIVE: to analyse the differences between genders in the description in the professional, domestic and total work hours and assess its association with health-related behaviour among nurses. METHODS: this is a transversal study carried out in 18 different public hospitals in the municipality of Rio de Janeiro. The data collection procedure was based on questionnaires. All nurses working with assistance were considered eligible (n=2,279. RESULTS: men and women showed significant differences in relation to working hours. The female group showed longer domestic and total work hours when compared to the group of men. In contrast, the number of hours spent on professional work was higher among men. For the women, both the professional hours and total work hours were often associated with excessive consumption of fried food and also coffee, lack of physical exercise and also the greater occurrence of overweight and obesity. CONCLUSION: both the professional hours and the domestic work hours need to be taken into account in studies about health, self-care and also the care provided within the context of nursing workers, particularly among women. The results add weight to the need for actions for health promotion in this occupational group and the importance of assessing the impact of long working hours on the health of workers.

Comparative studies of SC versus IV, IM versus IV, or IM versus SC have been sporadically conducted, and some new findings are completely different from the dosage recommendation as described in prescribing information. However, clinicians may still be ignorant of such new evidence-based findings when choosing treatment methods.Methods: A literature search was performed using PubMed, MEDLINE, and Web of Sciences™ Core Collection to analyze the advantages and disadvantages of SC, IV, and IM administration in head-to-head comparative studies.Results: “SC better than IV” involves trastuzumab, rituximab, antitumor necrosis factor medications, bortezomib, amifostine, recombinant human granulocyte-macrophage colony-stimulating factor, granulocyte colony-stimulating factor, recombinant interleukin-2, immunoglobulin, epoetin alfa, heparin, and opioids. “IV better than SC” involves ketamine, vitamin K1, and abatacept. With respect to insulin and ketamine, whether IV has advantages over SC is determined by specific clinical circumstances. “IM better than IV” involves epinephrine, hepatitis B immunoglobulin, pegaspargase, and some antibiotics. “IV better than IM” involves ketamine, morphine, and antivenom. “IM better than SC” involves epinephrine. “SC better than IM” involves interferon-beta-1a, methotrexate, human chorionic gonadotropin, hepatitis B immunoglobulin, hydrocortisone, and morphine.

    Single-dose disposition kinetics of difloxacin (5mg/kg bodyweight) were determined in clinically normal male dromedary camels (n=6) following intravenous (IV) and intramuscular (IM) administration. Difloxacin concentrations were determined by high performance liquid chromatography with fluorescence detection. The concentration-time data were analysed by compartmental and non-compartmental kinetic methods. Following a single IV injection, the plasma difloxacin concentration-time curve was best described by a two-compartment open model, with a distribution half-life (t(1/2alpha)) of 0.22+/-0.02h and an elimination half-life (t(1/2beta)) of 2.97+/-0.31h. Steady-state volume of distribution (V(dss)) and total body clearance (Cl(tot)) were 1.02+/-0.21L/kg and 0.24+/-0.07L/kg/h, respectively. Following IM administration, the absorption half-life (t(1)(/)(2ab)) and the mean absorption time (MAT) were 0.44+/-0.03h and 1.53+/-0.22h, respectively. The peak plasma concentration (C(max)) of 2.84+/-0.34microg/mL was achieved at 1.42+/-0.21h. The elimination half-life (t(1/2el)) and the mean residence time (MRT) was 3.46+/-0.42h and 5.61+/-0.23h, respectively. The in vitro plasma protein binding of difloxacin ranged from 28-43% and the absolute bioavailability following IM administration was 93.51+/-11.63%. Difloxacin could be useful for the treatment of bacterial infections in camels that are sensitive to this drug.

    Full Text Available The aim of the experiment was to study the effect of concentrates including legume seeds (Vicia faba var. minor or Pisum sativum on lamb performances and on meat quality, with an emphasis on intramuscular fatty acid composition. Thirty lambs (14.5 ± 3.45 kg live weight were randomly assigned to three dietary treatments: PEA group (concentrate including 400 g/kg of peas; FB group (concentrate including 380 g/kg of faba bean; SBM group (concentrate including 180 g/kg of soybean meal. Growth and slaughter performances were not affected by treatments as well as physical and proximate chemical meat characteristics. FB and SBM meat showed higher (P<0.001 vaccenic acid levels compared to PEA meat. Oleic acid was higher (P<0.05 in PEA meat compared to SBM meat while its level in FB meat was similar to counterparts. Linoleic acid levels tended to increase (P<0.10 in SBM lambs compared to PEA animals. PEA group showed higher (P<0.001 α-linolenic acid proportions compared to FB and SBM groups and a tendentially higher (P<0.10 eicosapentaenoic acid content compared to SBM meat. As a result, total n-3 fatty acids were higher (P<0.05 in PEA meat compared to SBM one while the proportions in FB meat were at intermediate level. These findings accounted for a lower and more favourable (P<0.001 n-6/n-3 ratio in PEA group compared to counterparts. Peas based-concentrate seemed to be more effective than faba bean- or soybean meal-included concentrates to improve the acidic profile of meat leading to higher α-linolenic acid levels and a lower n-6/n-3 ratio.

    Although goat milk production represents today a very small percentage of the world milk market, this percentage has been growing continuously during the past 20 years. Goat milk is the basic milk supply in many developing countries and provides tasteful derivative products in developed countries. Goats, as well as all milk-producing animals, can be affected by mastitis, but goats being considered a minor species, few drugs are specifically registered for these animals; most, at least for mastitis treatment, are usually tested and registered for use in cows. This situation leads often to the adoption for goat milk of withdrawal periods defined for cows even if these extrapolations prove almost never valid for goats. In the present study, the elimination of the β-lactam antibacterial agent ampicillin in goat milk was investigated. Ampicillin was chosen because it is one of the most common antibiotics used by goat farmers against mastitis due to the fact that it is well tolerated and has short elimination times in cows. Goats were treated with long-acting ampicillin at 15 mg (kg of body weight)(-1) by double intramuscular injection at 72 h interval. Milk was collected in a 12 h milking scheme. The method used to determine the levels of ampicillin in goat milk was based on a liquid-liquid extraction of this drug from the matrix, successive derivatization with formaldehyde, and final separation by HPLC with fluorescence detection. The results point out a slow depletion of ampicillin and, consequently, a withdrawal period (13 milkings) longer than that extrapolated and authorized for cows and sheep.

The USDA Choice boxed beef subprimals were purchased and aged for 14 d from boxed date. The AF, BF, GL, PT, SR, SM, SO, VI, VM, and VL (n = 10 each) were fabricated from subprimals. Crust-frozen AF, BF, SO, SM, and VL were cut into 2.54-cm steaks perpendicular to the long axis and grilled (71 degrees C). The PT, SR, VI, and VM were grilled (71 degrees C) as whole muscles, whereas the GL was grilled after cutting into anterior and posterior regions. Grilled muscles were cut into equal size sections perpendicular to long axis of muscles. Location-specific cores were prepared from each steak/section, and Warner-Bratzler shear force (WBSF) was measured. The muscle fiber orientations of BF, PT, and VI were bipennate, SR and SO were fusiform, and AD, SM, VL, GL, and VM were unipennate. The overall mean WBSF values for BF, SO, AF, SM, PT, SR, GL, VI, VM, and VL were 5.62, 4.86, 4.18, 4.90, 3.76, 4.44, 4.75, 4.78, 4.24, and 6.53 kg, respectively. Based on WBSF values, PT was tender, BF and VL were tough, and VM, VI, SM, GL SR, AF, and SO were intermediate. The first 2 proximal steaks of long head BF were more tender than the rest (P Dry or moist heat oven roasting, as compared with grilling, significantly tenderized SO (P = 0.002) and VL (P beef round.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are an integral component of equine analgesia, yet currently available NSAIDs are both limited in their analgesic efficacy and have adverse effects. The NSAID ketorolac tromethamine (KT) is widely used in humans as a potent morphine-sparing analgesic drug but has not been fully evaluated in horses. The purpose of this study was to determine the pharmacokinetic profile of KT in horses after intravenous (i.v.), intramuscular (i.m.), and oral (p.o.) administration. Nine healthy adult horses received a single 0.5-mg/kg dose of KT via each route of administration. Plasma was collected up to 48 h postadministration and analyzed for KT concentration using HPLC/MS/MS. Noncompartmental analysis of i.v. dosage indicated a mean plasma clearance of 8.4 (mL/min)/kg and an estimated mean volume of distribution at steady-state of 0.77 L/kg. Noncompartmental analysis of i.v., i.m., and p.o. dosages indicated mean residence times of 2.0, 2.6, and 7.1 h, respectively. The drug was rapidly absorbed after i.m. and p.o. administration, and mean bioavailability was 71% and 57% for i.m. and p.o. administration, respectively. Adverse effects were not observed after i.v., i.m., and p.o. administration. More studies are needed to evaluate the analgesic and anti-inflammatory properties of KT in horses.

    Full Text Available Abstract Objective The objective of this study was to compare intramuscular (IM ziprasidone to conventional IM medications (haloperidol combined with lorazepam for the treatment of severe agitation in adolescents (age 12–17. Methods We retrospectively identified consecutive severe agitation episodes (defined as requiring physical restraint in adolescents treated with either IM ziprasidone or conventional IM agents in a psychiatric emergency room. For ziprasidone, the dosage was 20 mg for 23 episodes and 10 mg for 5 episodes. For 24 episodes treated with combined haloperidol and lorazepam, the dosages were 4.8 ± 0.3 SEM mg and 1.9 ± 0.4 mg respectively. Outcomes were the duration of restraint and need for adjunctive "rescue" medications within 60 minutes. These outcomes were decided prior to reviewing any records. Results No difference was found in restraint duration (ziprasidone, N = 28, 55 ± 5 minutes; haloperidol with lorazepam N = 24, 65 ± 7 minutes, P = NS. Use of "rescue" medications did not differ between the two groups. No changes in blood pressure were found, but pulse decreased 8.3 ± 2.4 for haloperidol with lorazepam and 8.9 ± 4.24 for ziprasidone (P = NS. No instances of excessive sedation or extra-pyramidal symptoms were documented. Conclusion In this study, IM ziprasidone appeared effective, well tolerated, and similar in clinical profile to combined conventional IM medications for treating severe agitation in adolescents. Given the reportedly favorable acute side effect profile of parenteral atypical agents, they may provide an alternative to conventional antipsychotics for treating acute agitation in both adult and adolescent populations. Future randomized, controlled studies are needed.

    There is little information about the simultaneous changes of intramuscular pressure (IMP) and oxygen saturation (StO(2)) of the paraspinal muscle under various conditions of posture and load. To measure simultaneously and compare IMP and StO(2) across a range of static trunk postures commonly observed during normal work tasks. A prospective study using a repeated-measure design in clinical setting. Sixteen healthy young men with no history of back pain. Simultaneous measurements of IMP by a flexible slit catheter and StO(2) by near infrared spectroscopy of the multifidus muscle were performed. The two measures were taken in six static posture tasks: standing upright and bending forward with and without load (20kg), bending backward and during a sustained isometric contraction (ie, Sorensen test). To compare the influence of the tasks on IMP and StO(2) variables, a one-way variance analysis with repeated measures was used. Spearman's rank correlation coefficient (rho) was determined between the two variables for each posture task. We observed only a moderate but significant correlation between IMP and StO(2) values in upright standing and a trend in bending forward positions with load (ppostures. In the mutifidus muscle, there is no evident linear relationship between IMP and StO(2) values in various static postures of the trunk in young males. This preliminary study shows that IMP may play a role on StO(2) only in some circumstances, such as a prolonged endurance test or in a bending forward position with a significant load bearing.

    Aims: The aim of this study was to determine the rate of response to weekly intramuscular (IM methotrexate (MTX in patients with low-risk GTN (LR-GTN. Settings and Design: The study was designed cross-sectional and prospectively. Patients followed for 1 year. Materials and Methods: From 2006 to 2011, a total of 117 women with LR-GTN were studied. A weekly MTX regimen (50 mg/m 2 with dose escalation to 75 mg/m 2 was administered to 87 of patients. A biweekly pulsed intravenous bolus of 1.25 mg/m 2 of actinomycin D was administered in patients resistant to MTX (n = 30 and combination therapy was performed in those who did not respond to aforesaid treatments (n = 8. Statistical Analysis: The data were analyzed using Statistical Package for Social Sciences (SPSS 11.5 and Chi-square model was applied. Descriptive statistics and compare means (t-test was used as well. P < 0.05 was statistically significant. Results: All 117 patients with LR-GTN were cured. The primary remission rate was 74.3%, with primary dose of 50 mg/m 2 of MTX and escalation to 75 mg/m 2 . Another patient achieved complete remission with actinomycin and combination chemotherapy. There were significant statistical correlation between remission and World Health Organization (WHO scoring, International Federation of Gynecology and Obstetrics (FIGO staging, pretreatment beta-human chorionic gonadotropin (β-hCG level, and antecedent pregnancy (P < 0.05. Conclusion: We suggest that cases with score ≥6 should be considered high risk. First-line combination chemotherapy is advised in GTN with score ≥6.

    Having acquired near infrared (NIR) hyperspectral images of intact pork loin samples through an NIR hyperspectral imaging system, the efficiency of a variety of image processing techniques including texture pattern analysis techniques were applied to process hyperspectral images so as to determine the intramuscular fat (IMF) content non-destructively. After the segmentation of region of interest (ROI), the raw spectral, texture-based spectral and textural characteristics of pork images were extracted by spectral averaging and pattern recognition techniques namely Gabor filter and improved gray level co-occurrence matrix (GLCM), respectively. First derivatives of the non-filtered and the Gabor filtered spectra were also investigated. Full waveband partial least squares regression (PLSR) was employed to determine the optimal parameters of Gabor filter and GLCM, and to select optimal wavelengths for IMF prediction. A stepwise procedure was applied to the optimal wavelengths to further optimize them to key wavelengths. Multiple linear regression (MLR) models were built based on the key wavelengths. Mean spectra and the Gabor filtered spectra outperformed GLCM. The best result, represented by correlation coefficients of calibration (Rc), cross validation (Rcv) and prediction (Rp) of 0.89, 0.89, and 0.86, respectively, was achieved using the first derivative of Gabor filtered spectra at 1193 and 1217 nm. To visualize the IMF content in pork, the distribution maps of IMF content in pork were drawn using a mean spectra-based MLR model. These promising results highlight the great potential of NIR hyperspectral imaging for non-destructive prediction of IMF content of intact pork.

    A 30-year-old man was referred for a painful mass in the left calf and planovalgus deformity of the left foot. The pain had been present for 15 years but recently had become severe. On examination there was a visible, exquisitely tender mass in the medial distal aspect of the lower leg. There was valgus deformity of the hindfoot, abduction of the forefoot, and complete loss of the longitudinal arch which was passively correctable to neutral. Magnetic resonance imaging showed a 3.035.5312.0-cm complex mass in the calf with a "bag of worms" appearance consistent with a vascular tumor. An incisional biopsy resulted in diagnosis of benign intermuscular hemangioma. A marginal resection of the mass was later performed. During operative resection, the tumor was found to involve the entire posterior tibialis muscle to the musculotendinous junction. The patient began full weight bearing 4 weeks postoperatively and was placed in an ankle-foot orthosis for correction of the planovalgus. At 19 months postoperative, he reported no pain and mild weakness of the left foot, and he had returned to full-time work. There was no recurrence of the tumor. Intermuscular hemangioma of the calf may cause acquired spasticity and equinus deformity of the foot. In addition, intramuscular hemangiomas have been reported to cause muscle weakness and tendon rupture. In this patient, the authors believe that the posterior tibialis muscle was weakened and elongated secondary to the replacement of the muscle tissue by the tumor, ultimately leading to the planovalgus deformity.

    Intramuscular triglycerides (IMTG) are assumed to form an important substrate source during prolonged endurance exercise in trained males. This study investigated the effects of endurance exercise and recovery diet on IMTG content in vastus lateralis muscle. Nine male cyclists were provided with a standardized diet for 3 days, after which they performed a 3-h exercise trial at a 55% maximum workload. Before and immediately after exercise and after 24 and 48 h of recovery, magnetic resonance spectroscopy (MRS) was performed to quantitate IMTG content. Muscle biopsies were taken after 48 h of recovery to determine IMTG content by using quantitative fluorescence microscopy. The entire procedure was performed two times; in one trial, a normal diet containing 39% energy (En%) as fat was provided (NF) and in the other a typical carbohydrate-rich athlete's diet (LF: 24 En% fat) was provided. During exercise, IMTG content decreased by 21.4 +/- 3.1%. During recovery, IMTG content increased significantly in the NF trial only, reaching preexercise levels within 48 h. In accord with MRS, fluorescence microscopy showed significantly higher IMTG content in the NF compared with the LF trial, with differences restricted to the type I muscle fibers (2.1 +/- 0.2 vs. 1.4 +/- 0.2% area lipid staining, respectively). In conclusion, IMTG content in the vastus lateralis muscle declines significantly during prolonged endurance exercise in male cyclists. When a normal diet is used, IMTG contents are subsequently repleted within 48 h of postexercise recovery. In contrast, IMTG repletion is impaired substantially when a typical, carbohydrate-rich athlete's diet is used. Data obtained by quantitative fluorescence microscopy correspond well with MRS results, implying that both are valid methods to quantify IMTG content.

    The aim of this study was to investigate cytokine levels in the masseter muscle, their response to experimental tooth-clenching and their relation to pain, fatigue and psychological distress in patients with temporomandibular disorders (TMD) myalgia. Forty women, 20 with TMD myalgia (Diagnostic Criteria for TMD) and 20 age-matched healthy controls participated. Intramuscular microdialysis was performed to sample masseter muscle cytokines. After 140 min (baseline), a 20-minute tooth-clenching task was performed (50% of maximal voluntary contraction force). Pain (Numeric rating scale 0-10) and fatigue (Borg's Ratings of Perceived Exertion 6-20) were assessed throughout microdialysis, while pressure-pain thresholds (PPT) were assessed before and after microdialysis. Perceived stress (PSS-10) and Trait Anxiety (STAI) were assessed before microdialysis. The levels of IL-6, IL-7, IL-8 and IL-13 were higher in patients than controls (Mann Whitney U-test; P's tooth-clenching in both groups (Wilcoxon test; P's pain and fatigue than controls before and after tooth-clenching (P pain or fatigue. Also, there were no differences in stress or anxiety levels between groups. In conclusion, the masseter levels of IL-6, IL-7, IL-8 and IL-13 were elevated in patients with TMD myalgia and increased in response to tooth-clenching. Tooth-clenching increased jaw muscle pain and fatigue, but without correlations to cytokine levels. This implies that subclinical muscle inflammation may be involved in TMD myalgia pathophysiology, but that there is no direct cause-relation between inflammation and pain.

    Data on reptile analgesia are scarce for nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids and almost completely lacking in sea turtles, even though emergencies requiring correct pain management are very frequent in their rehabilitative medicine; therefore, dosage regimens extrapolated from other species involve the risk of clinical failure and damage to the animals. We describe the pharmacokinetic behavior of meloxicam in the loggerhead sea turtle (Caretta caretta). We chose meloxicam because of its selective anti-cyclooxygenase-2 activity and lesser adverse side effects. No data are available on the capacity of turtles to tolerate NSAIDs, so we chose a dose of 0.1 mg/kg of meloxicam. Plasma concentrations of meloxicam were unexpectedly low both for intravenous (IV; maximum concentration [C(max)] = 0.04±0.02 µg/mL) and intramuscular (IM; C(max) = 0.07±0.09 µg/mL) administration. A double-peak phenomenon occurred after both IV (time for second peak concentration T(max2) = 10.33±10.89 h) and IM (T(max2) = 1.17±0.75 h). The second peak after IM injection was premature, so some difficulty and delay in absorption appears to be an appropriate explanation. Furthermore, the area under the curve, and therefore systemic bioavailability (F = 31.82±28.24%), after both IV (0.30±0.29) and IM (0.10±0.03) injection appeared particularly limited. Terminal elimination slope and mean residence time indicated fast elimination after IM dosing; as a consequence, plasma concentrations dropped below analytic limits in 8 h. Considering that IM is the favored route of administration of drugs in rescue centers, it is unlikely that meloxicam at 0.1 mg/kg is an appropriate choice, particularly in long-term pain management protocols.

    Individual responses in creatine kinase (CK) release after eccentric exercise are divergent. This study aimed to identify whether this could be related to selected humoral or intramuscular inflammatory factors. Twenty-three subjects were divided into non-exercising (n = 5) and downhill run (DHR; n = 18) groups (12 × 5 min, 10% decline at 15 km/h). Blood samples were analyzed for white blood cell differential count, CK, myoglobin, tumor necrosis factor-α, granulocyte colony-stimulating factor, interleukin (IL)-1β, IL-6, and IL-10. Muscle biopsies were analyzed for signal transducer and activator of transcription-3 (STAT3), IκBα, and myeloperoxidase (MPO). DHR participants clustered as early (DHR1) recovery, biphasic response (DHR2), or classic delayed exaggerated CK response (DHR3), with a delayed CK peak (4784 ± 1496 U/L) on day 4. For DHR1 and DHR2, CK peaked on day 1 (DHR1: 1198 ± 837 U/L) or on day 1 and day 4 (DHR2: 1583 ± 448 U/L; 1878 ± 427 U/L), respectively. Immediately post-DHR, IL-6 increased in DHR2 and DHR3 whereas IL-10 increased in all DHR groups. STAT3 signaling increased for DHR1 and DHR2 at 4 h, but MPO at day 2 only in DHR2. Objective cluster analysis uncovered a group of subjects with a characteristic biphasic CK release after DHR. The second elevation was related to their early cytokine response. The results provide evidence that early responses following eccentric exercise are indicative of later variation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The pharmacokinetics of cefquinome was studied in plasma after a single dose (10 mg/kg) of intramuscular (i.m.) or intraperitoneal (i.p.) administration to tilapia (Oreochromis niloticus) in freshwater at 30 °C. Ten fish per sampling point were examined after treatment. The data were fitted to two-compartment open models following both routes of administration. The estimates of total body clearance (CL/F), volume of distribution (Vd/F), and absorption half-life (T1/2ka ) were 0.049 and 0.037 L/h/kg, 0.41 and 0.33 L/kg, and 0.028 and 0.035 h following i.m. and i.p. administration, respectively. After i.m. injection, the elimination half-life (T1⁄2β ) was calculated to be 5.81 h, the maximum plasma concentration (Cmax ) to be 49.40 μg/mL, the time to peak plasma cefquinome concentration (Tmax ) to be 0.14 h, and the area under the plasma concentration-time curve (AUC) to be 204.6 μg h/mL. Following i.p. administration, the corresponding estimates were 6.05 h, 44.39 μg/mL, 0.17 h and 267.8 μg h/mL. The minimum inhibitory concentrations of cefquinome, determined for 30 strains of Streptococcus agalactiae isolated from diseased tilapia, ranged from 0.015 to 0.12 μg/mL. Results from these studies support that 10 mg cefquinome/kg body weight daily could be expected to control tilapia bacterial pathogens inhibited in vitro by a minimal inhibitory concentration value of ≤2 μg/mL.

    The incidence of vitamin B12 deficiency after bariatric surgery can range from 26 to 70 %. There is no consensus on optimal vitamin B12 supplementation in postbariatric patients. The objective of this study was to compare three different regimes. In this retrospective matched cohort study, we included 63 patients with methylmalonic acid (MMA) levels ≥300 nmol/L. Group A (n = 21) received 6 intramuscular (im) vitamin B12 injections including a loading dose, group B (n = 21) received 3 im vitamin B12 injections without loading dose and group C (n = 21) received no im vitamin B12 injections. The total post-bariatric patient population consisted of 14 males (22.2 %) and 49 women (77.8 %) with a mean current body mass index of 30.6 ± 8.0 kg/m(2). There was no significant difference in vitamin B12 and MMA levels between 3 groups at baseline. There was a significant difference in follow-up vitamin B12 levels of group A compared to group B (p = 0.02) and group A compared to group C (p = 0.03). In the follow-up results, there is also a significant decrease in MMA levels of group A compared to group B (p = 0.02), group A compared to group C (p vitamin B12 deficiency. An injection regime with 6 injections recovered all vitamin B12 deficiencies biochemically. MMA levels cannot recover spontaneously over time without additional im injection regime.

    Full Text Available The quality of 40 carcasses of light lambs of the synthetic population of Slovak Dairy sheep from (a artificial rearing (AR and (b traditional rearing (TR was assessed on the basis of fatty acids profile of intramuscular fat (IMF. Lambs from AR in comparison with TR were of lower quality as assessed on the basis of fatty acids (FAs profile. The content of conjugated linolic acid (CLA in the fat of TR lambs was severalfold higher (0.749 vs. 0.193 g.100g-1 FAME, P<0.001 than in AR lambs. Similarly, the content of trans-vaccenic (TVA, á-linolenic (ALA, rumenic (RA, eicosapentaenoic (EPA and docosahexaenoic acid (DHA was in TR lambs significantly higher (P<0.001 than in AR lambs (0.955 vs. 0.111; 0.715 vs. 0.251; 0.672 vs. 0.148; 0.352 vs. 0.061; 0.252 vs. 0.079 g.100g-1 FAME. In contrary, the content of linoleic acid (LA, the ratio of LA/ALA and n-6/n-3 in AR lambs was higher than in TR lambs (9.07 vs. 4.81 g.100 g-1 FAME; 39.11 vs. 6.80; 14.56 vs. 3.25, P<0.001. In TR lambs the content of n-3 PUFA and BCFA was significantly higher (P<0.001 than in AR lambs (2.08 vs. 0.84 and 1.95 vs. 0.45. The value of thrombogenic index was higher in AR lambs in comparison with TR lambs (1.44 vs. 1.31; P<0.05. Significant differences between FAs of IMF of ram lambs and ewe lambs were observed only in the case of arachidonic acid (P<0.05.

    Cattle behavior, including measures of docility, is important to beef cattle producers not only from a human safety perspective but also due to potential correlations to economically relevant traits. Field data from the American Hereford Association was used to estimate genetic parameters for chute score (CS; = 25,037), weaning weight (WW; = 24,908), yearling weight (YW; = 23,978), and intramuscular fat percentage (IMF; = 12,566). Single-trait and bivariate animal models were used to estimate heritabilities and genetic correlations. All models included fixed effects of sex and contemporary group, defined as herd-year-season, and direct genetic and residual components were included as random effects. For CS and WW, additional random effects of maternal genetic and maternal permanent environment were also fitted. For CS, WW, YW, and IMF, heritability estimates were 0.27 ± 0.02, 0.35 ± 0.03, 0.36 ± 0.02, and 0.27 ± 0.02, respectively. Genetic correlations between CS and WW, CS and YW, CS and IMF, WW and YW, WW and IMF, and YW and IMF were -0.12 ± 0.06, -0.10 ± 0.05, -0.08 ± 0.06, 0.47 ± 0.05, -0.19 ± 0.09, and -0.41 ± 0.05, respectively. Heritability estimates for all traits suggest that they would respond favorably to selection and that selection for increased WW or YW could decrease marbling. Genetic correlations between CS and WW, YW, and IMF were all favorable but weak, suggesting that selection for improved docility will not have negative consequences on growth or carcass quality. Furthermore, maternal additive and maternal permanent environmental variances for CS were near 0, suggesting that their inclusion in National Cattle Evaluations is not warranted.

    The objective of this study was to assess the role of AMPK in intramus-cular fat (IMF) and fiber type in chicken muscle. The chickens were slaughtered and their muscles were col ected at the ages of 4, 8, and 16 weeks so as to de-termine the IMF contents, as wel as the expression levels of AMPK subunits, regu-lators of adipogenesis. In addition, the myosin heavy chains (MyHCs) in thigh mus-cle tissues were also measured. The results showed that the IMF contents in 16-week old chickens were higher than those in 4 and 8-week-old chickens (P<0.05). The expression levels of fatty acid synthase (FAS) and fatty aicd translocase CD36 (FAT/CD36) mRNA were increased significantly in samples col ected at the ages of 4 and 16 weeks (P<0.05). The expression levels of MyHC IIa and IIb differed sig-nificantly among al the developmental stages (P<0.05). The AMPKα2, AMPKγ1, and AMPKγ3 mRNA levels were dramatical y decreased with the increase of age (P<0.05). To examine the role of AMPK in adipogenesis regulation, the SV cel s were cultured in an adipogenesis medium and treated with AICAR and Compound C respectively, the specific activator and inhibit of AMPK. The Compound C induced dramatical y a greater expression of C/EBPβ, SREBP1 and PPARγ (P<0.05). In conclusion, the expression of AMPKα2, AMPKγ1, and AMPKγ3 mRNA is signifi-cantly correlated with the adipogenesis in skeletal muscle of chickens.

    The article introduces the hypothesis that intramuscular connective tissue, in particular the fascial layer known as the perimysium, may be capable of active contraction and consequently influence passive muscle stiffness, especially in tonic muscles. Passive muscle stiffness is also referred to as passive elasticity, passive muscular compliance, passive extensibility, resting tension, or passive muscle tone. Evidence for the hypothesis is based on five indications: (1) tonic muscles contain more perimysium and are therefore stiffer than phasic muscles; (2) the specific collagen arrangement of the perimysium is designed to fit a load-bearing function; (3) morphological considerations as well as histological observations in our laboratory suggest that the perimysium is characterized by a high density of myofibroblasts, a class of fibroblasts with smooth muscle-like contractile kinetics; (4) in vitro contraction tests with fascia have demonstrated that fascia, due to the presence of myofibroblasts, is able to actively contract, and that the resulting contraction forces may be strong enough to influence musculoskeletal dynamics; (5) the pronounced increase of the perimysium in muscle immobilization and in the surgical treatment of distraction osteogenesis indicates that perimysial stiffness adapts to mechanical stimulation and hence influences passive muscle stiffness. In conclusion, the perimysium seems capable of response to mechanostimulation with a myofibroblast facilitated active tissue contraction, thereby adapting passive muscle stiffness to increased tensional demands, especially in tonic musculature. If verified, this new concept may lead to novel pharmaceutical or mechanical approaches to complement existing treatments of pathologies which are accompanied by an increase or decrease of passive muscle stiffness (e.g., muscle fibroses such as torticollis, peri-partum pelvic pain due to pelvic instability, and many others). Methods for testing this new concept

    The plasma and milk pharmacokinetics of marbofloxacin, a fluoroquinolone antibacterial compound, were evaluated in dairy cows, as well as its pharmacodynamic characteristics against mastitis-isolated pathogens. Marbofloxacin was given intramuscularly as a 10% aqueous solution to dairy cows either at a single dose or at repeated doses of 2 mg/kg once daily for 3 d. Blood and milk samples were collected for the determination of the concentration of marbofloxacin and of its putative metabolites: N-desmethyl-marbofloxacin and N-oxide-marbofloxacin. Bacterial field isolates were from milk samples collected from dairy cows suspected of having an intramammary infection. After identification, the minimal inhibitory concentration (MIC) was determined against the isolated strains. The maximal marbofloxacin concentration (Cmax) observed in milk after the first administration was 1.024 microg/mL, and the area under the curve during the first dosing interval was 6.513 microg/h per milliliter. After the third administration, these parameters were slightly increased (about 20% at most). Both metabolites were detected in the milk, but their concentrations were below the limit of quantification. The MIC against 90% of the population (MIC90) of Escherichia coli was 0.016 microg/mL, and it was 0.229 microg/mL against Staphylococcus aureus. The following surrogate clinical outcome markers were obtained against E. coli strains: a Cmax/MIC ratio of 67 and an area under the curve/MIC ratio of 407 h. Hence, a possible efficacy of marbofloxacin in the treatment of E. coli-induced mastitis could be expected as the endpoints of 10 and 250 h, respectively, are reached.
