    Although labor unions traditionally have fought for shorter working hours, there have been recent reversals in this trend. The Pulp and Paperboard Division of Temple-Eastex Incorporated converted to a 12-hour shift and found that safety improved, productivity increased, and overtime decreased. (JOW)

    In April 1985, the operating crews at the Fast Flux Test Facility near Richland, Washington, changed their rotating shift schedule from an 8-hour to a 12-hour a day work schedule. The primary purpose of the change was to reduce the attrition of operators by increasing their job satisfaction. Eighty-four percent of the operators favored the change. A program was established to evaluate the effects on plant performance, operator alertness, attrition, sleep, health, job satisfaction, and off-the-job satisfaction. Preliminary results from that evaluation program indicate that the 12-hour shift schedule is a reasonable alternative to an 8-hour schedule at this facility

    Full Text Available The present study compared a 12-hour and an 8-hour shift system in 18 Austrian rail traffic controllers. To gain objective indicators for arousal and fatigue induced by the whole workrest sequence, we recorded heart rate during the last night shift, in addition to subjective measures that included physical symptoms. A higher increase of monotony, fatigue and saturation emerged during the 8-hour compared to the 12-hour regime, together with a heart rate decrease during the last 8-hour night shift. In line with other researchers, we conclude that flexible working conditions in specific occupational groups may compensate for disadvantages of prolonged working periods, giving way to advantages of longer shifts such as longer pauses and extra days off for social and other personal activities.

    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.)

    Full Text Available intramammary administration to establish the optimum withdrawal time, therapeutic efficacy, and its influence on milk yield. Materials and method. Twelve healthy lactating Holstein cows were selected from the University of Antioquia’s teaching dairy herd (Colombia, were randomly assigned to a control (n=6 group or florfenicol (n=6 group that received 20 mg/kg of florfenicol by intramammary and intramuscular routes, with a 15 days washout period between treatments. Results. The Tmax and Cmax for the intramuscular route were 6 hoursand 2.86 mg/L respectively. The Tmax and Cmax for the intramammary route, were estimated at 0 hour and about 20000 mg/L respectively by extrapolated from regression line. The florfenicol elimination phase in milk had an average half-life of elimination (t½ of 19.8 hours and 4.9 hours for intramuscular and intramammary administration, respectively. The therapeutic efficacy only was reached by intramammary route, when minimal inhibitory concentration (M.I.C. of florfenicol by Stahphylococcus aureus, was used as reference value. There was no statistically significant difference in milk yield between treated and non-treated cows. Conclusions. According to these results, post-treatment milk withdrawal should be no less than 3 days for intramammary administration, and at least 7 days for intramuscular administration. The therapeutic efficacy only was reached by intramammary route. In addition, there was no statistically significant difference in milk yield between treated and nontreated cows.

    To assess the population pharmacokinetics of methadone in deer. Prospective non-randomized experimental trial. Twelve healthy adult sika deer (nine males and three females). Deer received intramuscular administration of racemic methadone hydrochloride at 0.5 mg kg(-1) or 1 mg kg(-1) . Plasma methadone and its metabolite 2-Ethylidene-1,5-Dimethyl-3,3-Diphenyl-Pyrolidine (EDDP) concentrations were determined by validated liquid chromatography coupled to tandem mass spectrometry methods, at times 0, 30 minutes, 1, 2, 3, 4, 5, 6, 8, 12 and 24 hours. Population pharmacokinetics analysis was undertaken using a non-linear mixed effects modelling (NONMEM). A two-compartment linear disposition model best described observed time-concentration profiles of methadone and EDDP. Population parameter estimates of methadone were elimination clearance (17.3 L hour(-1) ), metabolic clearance (34.6 L hour(-1) ), volume of distribution of compartment 1 (216.0 L) and volume of distribution of compartment 2 (384.0 L). Population parameter estimates of EDDP were elimination clearance (121.0 L hour(-1) ), volume of distribution of compartment 3 (1.08 L) and volume of distribution of compartment 4 (499.5 L). The total clearance and total volume of distribution of methadone and EDDP were 51.9 L hour(-1) , 121.0 L hour (-1) , 600.0 L and 500.6 L, respectively. The methadone terminal elimination half-life was 8.19 hours. No adverse effects were observed after methadone administration. Following intramuscular injection, methadone was characterized by a large total volume of distribution, high systemic clearance and intermediate terminal half-life in sika deer. © 2014 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    The purpose of this study was to compare efficacy and safety among intramuscular olanzapine, intramuscular haloperidol, orally disintegrating olanzapine tablets, and oral risperidone solution for agitated patients with psychosis during the first 24 hours of treatment in an acute care psychiatric ward. Forty-two inpatients from an acute care psychiatric ward of a medical center in central Taiwan were enrolled. They were randomly assigned to 1 of the 4 treatment groups (10-mg intramuscular olanzapine, 10-mg olanzapine oral disintegrating tablet, 3-mg oral risperidone solution, or 7.5-mg intramuscular haloperidol). Agitation was measured by using the excited component of the Positive and Negative Syndrome Scale (PANSS-EC), the Agitation-Calmness Evaluation Scale, and the Clinical Global Impression--Severity Scale during the first 24 hours. There were significant differences in the PANSS-EC total scores for the 4 intervention groups at 15, 30, 45, 60, 75, and 90 minutes after the initiation of treatment. More significant differences were found early in the treatment. In the post hoc analysis, the patients who received intramuscular olanzapine or orally disintegrating olanzapine tablets showed significantly greater improvement in PANSS-EC scores than did patients who received intramuscular haloperidol at points 15, 30, 45, 60, 75, and 90 minutes after injection. These findings suggest that intramuscular olanzapine, orally disintegrating olanzapine tablets, and oral risperidone solution are as effective treatments as intramuscular haloperidol for patients with acute agitation. Intramuscular olanzapine and disintegrating olanzapine tablets are more effective than intramuscular haloperidol in the early phase of the intervention. There is no significant difference in effectiveness among intramuscular olanzapine, orally disintegrating olanzapine tablets, and oral risperidone solution.

    As reported in our previous issue (page 27), on 28 February Volker Soergel stepped down after serving as Chairman of the Board of the DESY Laboratory in Hamburg since January 1981, when the previous chairman, Herwig Schopper, moved to become Director General of CERN. DESY is now headed by Bjorn Wiik. During the twelve years of Soergel's mandate, DESY substantially evolved and progressed. Dominating the landscape was the big HERA electron-proton collider - the world's first - proposed, approved, constructed and commissioned under Soergel's leadership. As well as pioneering electron-proton collisions, HERA also broke new ground in international collaboration. At the approval of the project by the German government, it had already been made clear that both the machine and its experiments had to be built with full international cooperation, using material contributions from foreign institutes. With the difficult task of transforming these requirements into hard reality, Volker Soergel succeeded brilliantly. The 'HERA model', with interested countries pledging contributions in equipment and/or manpower, established a new route to major project involvement. For HERA, the substantial Italian contribution, organized by Antonino Zichichi, was vital to the success of the project

    Crossover. To compare the time required to decrease intramuscular temperature 8°C below baseline temperature, and to compare intramuscular temperature 90 minutes posttreatment, between 2 cryotherapy modalities. Cryotherapy is used to treat pain from muscle injuries. Cooler intramuscular temperatures may reduce cellular metabolism and secondary hypoxic injury to attenuate acute injury response, specifically the rate of chemical mediator activity. Modalities that decrease intramuscular temperature quickly may be beneficial in the treatment of muscle injuries. Eighteen healthy subjects received 2 cryotherapy conditions, crushed-ice bag (CIB) and cold-water immersion (CWI), in a randomly allocated order, separated by 72 hours. Each condition was applied until intramuscular temperature decreased 8°C below baseline. Intramuscular temperature was monitored in the gastrocnemius, 1 cm below subcutaneous adipose tissue. The primary outcome was time to decrease intramuscular temperature 8°C below baseline. A secondary outcome was intramuscular temperature at the end of a 90-minute rewarming period. Paired t tests were used to examine outcomes. Time to reach an 8°C reduction in intramuscular temperature was not significantly different between CIB and CWI (mean difference, 2.6 minutes; 95% confidence interval: -3.10, 8.30). Intramuscular temperature remained significantly colder 90 minutes post-CWI compared to CIB (mean difference, 2.8°C; 95% confidence interval: 2.07°C, 3.52°C). There was no difference in time required to reduce intramuscular temperature 8°C 1 cm below adipose tissue using CIB and CWI. However, intramuscular temperature remained significantly colder 90 minutes following CWI. These results provide clinicians with information that may guide treatment-modality decisions.

    To consider to what extent intramuscular injection technique can be described to remain entrenched in ritualistic practice and how evidence-based practice should be considered and applied to the nursing practice of this essential skill. The notion of rituals within nursing and the value or futile impact they afford to this essential nursing skill will be critically reviewed. Discursive paper. Literature review from 2002-2013 to review the current position of intramuscular injection injections. Within the literature review, it became clear that there are several actions within the administration of an intramuscular injection that could be perceived as ritualistic and require consideration for contemporary nursing practice. The essential nursing skill of intramuscular injection often appears to fit into the description of a ritualised practice. By providing evidence-based care, nurses will find themselves empowered to make informed decisions based on clinical need and using their clinical judgement. For key learning, it will outline with rationale how site selection, needle selection, insertion technique and aspiration can be cited as examples of routinised or ritualistic practice and why these should be rejected in favour of an evidence-based approach. The effect on some student nurses of experiencing differing practices between what is taught at university and what is often seen in clinical practice will also be discussed. © 2014 John Wiley & Sons Ltd.

    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

The patient was diagnosed with Nicolau syndrome, a rare complication of intramuscular injection presumed to be related to the inadvertent intravascular injection. It was first reported following intramuscular injection of bismuth salt, but it can occur as a complication of various other drugs. Fasciotomy was carried out due to the resultant compartment syndrome and medical therapy with heparin, corticosteroid, and pentoxifyllin was initiated.

    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.

    Full Text Available Objective. To evaluate the safety and efficacy of intramuscular dexketoprofen for postoperative pain in patients undergoing hernia surgery. Methodology. 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.

    Full Text Available Necrotizing soft tissue fasciitis (NSTIs or necrotizing fasciitis is an infrequent and serious infection. Herein, we describe the clinical course of a female patient who received a diagnosis of NSTIs after gluteus intramuscular injection. We also report the results of our review of published papers from 1997 to 2017. Since now, 19 cases of NSTIs following intramuscular injections have been described. We focus on the correlation between intramuscular injection and NSTIs onset, especially in immunosuppressed patients treated with corticosteroids, suffering from chronic diseases or drug addicted. Intramuscular injections can provoke severe tissue trauma, representing local portal of infection, even if correctly administrated. Otherwise, it is important not to inject drug in subcutaneous, which is a less vascularized area and therefore more susceptible to infections. Likewise, a proper injecting technique and aspiration prior to injection seem to be valid measure to prevent intra-arterial or para-arterial drug injection with the consequent massive inflammatory reaction. Necrosis at the infection site appears to be independent of the drug, and it is a strong additional risk factor for NSTIs.

    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. 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.

    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 Intra-muscular hemangiomas (IMH are relatively uncommon benign vascular tumors, which account for less than 1% of all hemangiomas. IMH may be presented as a perceived sporting injury. Diagnosis of this lesion is important not only because of its rarity, but also due to dangers posed by misdiagnosis and mismanagement. They must be considered in the differential diagnosis of unexplained pain and swelling in muscles. IMH occurring in the oral cavity is reviewed below.

    Previous studies have validated the clinical use of opioids with kaap-receptor affinities for pain management in birds. Butorphanol, a kappa opioid receptor agonist and a mu opioid receptor antagonist, is currently considered by many clinicians to be the opioid of choice for this use. However, despite studies reporting the analgesic properties of butorphanol in psittacine birds, dosing intervals have not been established for any psittacine species. The goals of this study in the Hispaniolan Amazon parrot (Amazona ventralis) were to evaluate the pharmacokinetics of butorphanol tartrate after intravenous (IV), intramuscular (IM), and oral (PO) administration and to determine the bioavailability of butorphanol tartrate after oral administration. Twelve Hispaniolan Amazon parrots were used in the study, with a complete-crossover experimental design and a 3-month period separating each part of the study. The birds were randomly assigned to 3 groups (n = 4) for each stage. Butorphanol tartrate was administered once at a dose of 5 mg/kg in the basilic vein or pectoral muscles or as an oral solution delivered via feeding tube into the crop for the IV, IM, and PO studies, respectively. After butorphanol administration, blood samples were collected at 1, 5, 15, 30, 60, 90, 120, 180, and 240 minutes for the IV and IM studies and at 5, 15, 30, 60, 90, 120, 180, 240, and 300 minutes for the PO study. Because of the size limitation of the birds, naive pooling of datum points was used to generate a mean plasma butorphanol concentration at each time point. For each study, birds in each group (n = 4) were bled 3 times after dosing. Plasma butorphanol concentrations were determined by high-performance liquid chromatography/tandem mass spectrometry, and pharmacokinetic parameters were calculated. Butorphanol tartrate was found to have high bioavailability and rapid elimination following IM administration. In contrast, oral administration resulted in low bioavailability (Amazon

    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.

Open-label trial of IM injections of aripiprazole and 24-hour monitoring of clinical response in patients with major psychoses and acute agitation. Partial analysis of blood levels of the administered drug to correlate with clinical response. Acute psychiatric care wards in a single university hospital. A total of 201 acutely agitated patients (79 with schizophrenia and 122 with bipolar disorder I). Aripiprazole 9.75 mg IM injection. We evaluated clinical response using the Excitatory Component of the Positive and Negative Syndrome Scale (PANSS-EC), the Agitation/Calmness Evaluation Scale (ACES), and the Clinical Global Impressions scale (CGI). Assessments were conducted 30, 60, 90, and 120 minutes and 24 hours after the first injection for PANSS-EC and ACES, and 2, 4, 6, and 24 hours for CGI. Response was at least a 40% decrease in PANSS-EC scores. We measured serum aripiprazole and dehydroaripiprazole levels in a subsample. IM aripiprazole significantly improved clinical measures. PANSS-EC improved progressively, starting after 30 minutes. ACES improved after 90 minutes and continued thereafter. Effects were sustained, with steadily decreasing CGI scores, until the 24th hour. Response rate was 83.6% after 2 hours, but with repeat injections, it rose to over 90% with no differences among diagnostic groups. Although there were gender differences in the response to individual PANSS-EC items, the responses were similar overall. Neither clinical monitoring nor patient reporting revealed any side effects. No therapeutic window was identified, and levels did not correlate with any clinical measure. Aripiprazole was effective and safe in reducing acute agitation in patients with bipolar disorder or schizophrenia. Our results compare favorably to double-blind trials, probably

    Intramuscular degeneration process of Duchenne dystrophy skeletal muscles was investigated by longitudinal skeletal muscle imaging with high-field-strength NMR-CT of 1.5 Tesla. Thigh muscles in 10 cases ranging in age from 4 to 19 years were examined by T 1 -weighted longitudinal images (TR=215∼505 ms, TE=19∼20 ms). The following results were obtained. Skeletal muscle degeneration was depicted as high signal intensity area reflecting its high fat contents. These high signal intensity areas had a longitudinally streaky appearance in parallel direction with myofibers. These findings were more prominent toward myotendon junction than muscle bellies. Skeletal muscle degeneration progressed rapidly between 7 to 10 years of age, and reached a plateau after that. (author)

    Hargens, A. R.; Ballard, R. E.

    1995-01-01

    We review historical and methodological approaches to measurements of intramuscular pressure (IMP) in humans. These techniques provide valuable measures of muscle tone and activity as well as diagnostic criteria for evaluation of exertional compartment syndrome. Although the wick and catheter techniques provide accurate measurements of IMP at rest, their value for exercise studies and diagnosis of exertional compartment syndrome is limited because of low frequency response and hydrostatic (static and inertial) pressure artifacts. Presently, most information on diagnosis of exertional compartment syndromes during dynamic exercise is available using the Myopress catheter. However, future research and clinical diagnosis using IMP can be optimized by the use of a miniature transducer-tipped catheter such as the Millar Mikro-tip.

    The antiemetic effect of clebopride, a new derivative of the orthopramide group, was compared with that of placebo in 298 women undergoing elective surgery. A group of 150 patients received premedication of 1 mg/kg of meperidine, administered intramuscularly (IM), and a group of 148 patients received premedication of 10 mg of diazepam IM. All patients received 0.5 mg of atropine IM. Anesthesia was induced with thiopental and maintained with halogenated N2O/O2. In a double-blind procedure, clebopride (2 mg) or placebo was injected IM at the end of anesthesia and whenever a patient had a second episode of vomiting. Clebopride appeared to be better than placebo in the prevention of nausea (P less than or equal to 0.05) and vomiting (P less than or equal to 0.001) during the 12-hour observation period. The frequency of side effects was virtually the same in patients given clebopride and patients given placebo.

    2007-04-01

    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.

    2011-01-01

    The aim of the present study was to analyse magnetic resonance findings of intramuscular metastases (IM) in a relatively large series. From January 2000 to January 2010, 28 patients (207 metastases) were retrospectively identified in the radiological database of the Martin-Luther-University. Several different scanning protocols were used depending on the localisation of IM. In 12 patients diffusion-weighted (DW) images were obtained with a multi-shot SE-EPI sequence. Apparent diffusion coefficient (ADC) maps were also calculated. Furthermore, fusion images were manually generated between the DW and half-Fourier acquisition single-shot turbo spin echo (HASTE) images. On T2-weighted images, 97% of the recognised IM were hyperintense in comparison to unaffected musculature, and 3% were mixed iso- to hyperintense. On T1-weighted images most IM (91%) were homogeneously isointense in comparison to muscle tissue, whereas 4% were hypointense, and 5% lightly hyperintense. ADC maps were calculated for 91 metastases ranging from 0.99 to 4.00 mm 2 s -1 (mean value 1.99 ± 0.66). ADC values of low ( 3.0) in 6%. Of the IM that were investigated with contrast medium, 88.5% showed marked enhancement. It was homogeneous in 88% and heterogenous in 6%. Rim enhancement with central low attenuation was seen in 6%. There was no difference in enhancement characteristics with respect to ADC values or fusion patterns. Peritumoral enhancement was identified in 2.4%. Magnetic resonance features of muscle metastases are relatively typical and consist of round or oval intramuscular masses with well-defined margins, marked enhancement, low or moderate ADC values, and moderate to high signal intensity on fusion images.

    We present a case of Mazabroud's syndrome, a rare benign disease, with multiple intramuscular myxomas of the thoracic wall associated with fibrous dysplasia of bone. CT, MR imaging and ultrasonography (US) of the thorax showed 2 well circumscribed homogeneous intramuscular tumors. A US-guided needle biopsy with a large-core needle (2.0 mm) and a fine needle (0.8 mm) showed that the tumors were intramuscular myxomas with no sign of malignancy. 99m Tc bone scintigraphy showed a markedly increased uptake in the right lower skull, and multiple smaller foci. CT of the skull revealed a right-sided unilateral bone thickening of the orbit and the ethomoidal cells, and right-sided exophthalmia. This case history suggests that patients with multiple intramuscular myxomas should be preoperatively examined for osseous lesions. A postoperative follow-up should also be performed to detect other soft-tissue myxomas not as yet clinically detectable, or rare osseous complications. (orig.)

    This paper studies the link between working hours and productivity using daily information on working hours and performance of a sample of call centre agents. We exploit variation in the number of hours worked by the same employee across days and weeks due to central scheduling, enabling us to estimate the effect of working hours on productivity. We find that as the number of hours worked increases, the average handling time for a call increases, meaning that agents become less productive. Th...

    From 1988 to June 2000 138 transplantations were performed in 129 adult patients. Actuarial patient and graft survivals have been 80.7% and 75.4% at one year and 67.8% and 63.5% at 10 years. This compares favourably with the statistics of the European Liver Transplant Registry that collected data from more than 30,000 grafts. Over the twelve years of activity, the indications have become more liberal and the techniques have been simplified. The waiting list has therefore grown and some patients are now unfortunately dying before a graft can be found because the number of brain dead donors remains stable. In order to palliate this shortage, older donors are now being accepted even with co-morbidities and/or moderate alterations of the liver function tests. The use of live donors and the split of the best cadaveric grafts for two recipients will also reduce the gap between the demand and the offer.

    Full Text Available Abstract Background The severity of associated soft tissue trauma in complex injuries of the extremities guides fracture treatment and decisively determines patient's prognosis. Trauma-induced microvascular dysfunction and increased tissue pressure is known to trigger secondary soft tissue damage and seems to adversely affect skeletal muscle function. Methods 20 patients with isolated tibial fractures were included. Blood pressure and compartment pressure (anterior and deep posterior compartment were measured continuously up to 24 hours. Corresponding perfusion pressure was calculated. After 4 and 12 weeks isokinetic muscle peak torque and mean power of the ankle joint in dorsal and plantar flexion were measured using a Biodex dynamometer. Results A significant inverse correlation between the anterior perfusion pressure at 24 hours and deficit in dorsiflexion at 4 weeks was found for both, the peak torque (R = -0.83; p Conclusion The functional relationship between the decrease in intramuscular perfusion pressures and muscle performance in the early rehabilitation period indicate a causative and prognostic role of early posttraumatic microcirculatory derangements and skeletal muscle function. Therapeutic concepts aimed at effective muscle recovery, early rehabilitation, and decreased secondary tissue damage, should consider the maintenance of an adequate intramuscular perfusion pressure.

    To compare the efficacy and safety profile between intramuscular (IM) olanzapine and IM haloperidol plus IM lorazepam in acute schizophrenic patients with moderate to severe agitation. This was a prospective, randomized, open-label study. Acutely agitated patients with schizophrenia or schizoaffective disorder (n = 67) were randomized to receive 10 mg IM olanzapine (n = 37) or 5 mg IM haloperidol plus 2 mg IM lorazepam (n = 30). Agitation was measured with Positive and Negative Syndrome Scale Excited Component (PANSS-EC) and Agitation-Calmness Evaluation Scale (ACES) during the first 2 hours and at 24 hours after the first injection. Safety was assessed using the Simpson-Angus Scale and Barnes Akathisia Rating Scale and by recording adverse events at 24 hours following the first injection. The Clinical Global Impression-Severity scale was also rated. The PANSS-EC scores decreased significantly at 2 hours after the first injection in both groups (olanzapine: -10.2, p haloperidol + lorazepam: -9.9, p Haloperidol plus lorazepam was not inferior to olanzapine in reducing agitation at 2 hours. There were no significant differences in PANSS-EC or ACES scores between the two groups within 2 hours following the first injection. The frequencies of adverse events and changes in Clinical Global Impression-Severity, Simpson-Angus Scale, and Barnes Akathisia Rating Scale scores from baseline to 24 hours showed no significant differences between the groups. The findings suggest that IM haloperidol (5 mg) plus lorazepam (2 mg) is not inferior to IM olanzapine (10 mg) in the treatment of acute schizophrenic patients with moderate to severe agitation (ClinialTrials.gov identifier number NCT00797277).

    The heating characteristics of a stationary device delivering sustained acoustic medicine with low-intensity therapeutic ultrasound (LITUS) are unknown. To measure intramuscular (IM) heating produced by a LITUS device developed for long-duration treatment of musculoskeletal injuries. Controlled laboratory study. University research laboratory. A total of 26 healthy volunteers (16 men, 10 women; age = 23.0 ± 2.1 years, height = 1.74 ± 0.09 m, mass = 73.48 ± 14.65 kg). Participants were assigned randomly to receive active (n = 20) or placebo (n = 6) LITUS at a frequency of 3 MHz and an energy intensity of 0.132 W/cm(2) continuously for 3 hours with a single transducer or dual transducers on the triceps surae muscle. We measured IM temperature using thermocouples inserted at 1.5- and 3-cm depths into muscle. Temperatures were recorded throughout treatment and 30 minutes posttreatment. We used 2-sample t tests to determine the heating curve of the LITUS treatment and differences in final temperatures between depth and number of transducers. A mild IM temperature increase of 1 °C was reached 10 ± 5 minutes into the treatment, and a more vigorous temperature increase of 4 °C was reached 80 ± 10 minutes into the treatment. The maximal steady-state IM temperatures produced during the final 60 minutes of treatment at the 1.5-cm depth were 4.42 °C ± 0.08 °C and 3.92 °C ± 0.06 °C using 1 and 2 transducers, respectively. At the 3.0-cm depth, the maximal steady-state IM temperatures during the final 60 minutes of treatment were 3.05 °C ± 0.09 °C and 3.17 °C ± 0.05 °C using 1 and 2 transducers, respectively. We observed a difference between the temperatures measured at each depth (t78 = -2.45, P = .02), but the number of transducers used to generate heating was not different (t78 = 1.79, P = .08). The LITUS device elicited tissue heating equivalent to traditional ultrasound but could be sustained for multiple hours. It is a safe and effective alternative tool

    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.

    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.

    The author proposes twelve brief notes aimed at discussing the reduction of fossil energy consumption in order to reduce CO 2 emissions and to improve the French energy supply security, without any useless expense. These notes address the reason for energy savings, the cost and price of a CO 2 ton, the issue of thermal regulation for buildings (it's not in compliance with the law, and results in higher expenses and increased CO 2 emissions), the introduction of a carbon tax to incite investments for energy saving, the status and health of the CO 2 European market, the support of actions aimed at reducing fossil energy consumption, the fact that bio-heat is ten times more efficient than bio-fuel and that therefore car holders should finance bio-heat, the development of hybrid uses of energy to avoid the difficulty of energy storage, the reduction of CO 2 emissions at low cost (by consuming as much renewable energy as nuclear energy but without wind or photovoltaic energy), the cost of less CO 2 , less fossil energy and less nuclear, and the interest of France to act on its own to reduce CO 2 emissions. The author proposes a brief synthesis of these notes and some proposals regarding thermal regulation for buildings, taxes, the European CO 2 market, the forest biomass, electricity production, and the European and word dimensions of these issues

    Full Text Available Intravenous haloperidol has been associated with torsades de pointes (TdP. These two sudden deaths were probable adverse drug reactions (ADRs following intramuscular (IM antipsychotics. The autopsies described lack of heart pathology and were highly compatible with the possibility of TdP in the absence of risk factors other than the accumulation of antipsychotics with a high serum peak after the last injection, leading to death within hours. The first case was a 27-year-old African-American male with schizophrenia but no medical issues. His death was probably caused by repeated IM haloperidol injections of 10 mg (totaling 35 mg in 2 days. The second case involves a 42-year-old African-American female with metabolic syndrome. Her probable cause of death was the last ziprasidone IM injection of 20 mg in addition to (1 three extra haloperidol doses (2 hours before the ziprasidone injection, 5 mg oral haloperidol; approximately 21 hours earlier, 5 mg oral haloperidol; and 2 days prior, one 10 mg IM haloperidol injection, (2 10 mg/day of scheduled oral haloperidol for 6 days before death, and (3 a long-acting paliperidone injection of 156 mg 18 days before death. The study of haloperidol glucuronidation and its impairment in some African-Americans is urgently recommended.

    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.

    The Zagreb regimen, an abbreviated intramuscular schedule for rabies vaccination, was developed by I. Vodopija and colleagues of the Zagreb Institute of Public Health in Croatia in the 1980s. It was recommended by WHO as one of the intramuscular (IM) schedules for rabies vaccination in 2010. We reviewed the literature on the immunogenicity, safety, economic burden, and compliance of the Zagreb 2-1-1 regimen. Compared to Essen, another IM schedule recommended by WHO, Zagreb has higher compliance, lower medical cost, and better immunogenicity at an early stage.

    Sixty patients presenting for in-patient gynaecological laparoscopic surgery were randomly allocated to receive either diclofenac 75 mg (n = 20), ketorolac 30 mg (n = 20) or piroxicam 20 mg (n = 20) as an intra-muscular injection immediately after induction of anaesthesia. Postoperative visual analogue scores over the first 24 hours, using a 10 cm scale, ranged from 3.2-0.5 in the diclofenac group, 2.7-0.85 in the ketorolac group and 2.8-0.5 in the piroxicam group. The scores did not differ significantly between the three groups (p > 0.05). Mean time (SD) to first analgesia was 27(94) minutes in the piroxicam group, 16 (30) minutes in the diclofenac group and 62 (120) minutes in the piroxicam group. Six out of twenty patients in the diclofenac group required further analgesia compared to nine out of twenty in the other two drug groups. This difference was not significant. There were no reports of increased bleeding, bronchoconstriction, bleeding from the upper gastrointestinal tract, renal impairment or pain from the intra-muscular injection site in any of the groups. The administration of a non-steroidal anti-inflammatory drug to patients presenting for laparoscopic surgery reduces postoperative pain. There were no obvious differences between the agents used.

    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

  14. The neuroprotective effects of intramuscular insulin-like growth factor-I treatment in brain ischemic rats.

    Directory of Open Access Journals (Sweden)

    Heng-Chih Chang

    Full Text Available Brain ischemia leads to muscle inactivity-induced atrophy and may exacerbate motor function deficits. Intramuscular insulin-like growth factor I (IGF-I injection has been shown to alleviate the brain ischemia-induced muscle atrophy and thus improve the motor function. Motor function is normally gauged by the integrity and coordination of the central nervous system and peripheral muscles. Whether brain ischemic regions are adaptively changed by the intramuscular IGF-I injection is not well understood. In this study, the effect of intramuscular IGF-I injection was examined on the central nervous system of brain ischemic rats. Rats were divided into 4 groups: sham control, brain ischemia control, brain ischemia with IGF-I treatment, and brain ischemia with IGF-I plus IGF-I receptor inhibitor treatment. Brain ischemia was induced by right middle cerebral artery occlusion. IGF-I and an IGF-1 receptor inhibitor were injected into the affected calf and anterior tibialis muscles of the treated rats for 4 times. There was an interval of 2 days between each injection. Motor function was examined and measured at the 24 hours and 7 days following a brain ischemia. The affected hind-limb muscles, sciatic nerve, lumbar spinal cord, and motor cortex were collected for examination after euthanizing the rats. IGF-I expression in the central nervous system and affected muscles were significantly decreased after brain ischemia. Intramuscular IGF-I injection increased the IGF-I expression in the affected muscles, sciatic nerve, lumbar spinal cord, and motor cortex. It also increased the p-Akt expression in the affected motor cortex. Furthermore, intramuscular IGF-I injection decreased the neuronal apoptosis and improved the motor function. However, co-administration of the IGF-I receptor inhibitor eliminated these effects. Intramuscular IGF-I injection after brain ischemia attenuated or reversed the decrease of IGF-I in both central and peripheral tissues, and

    To evaluate and compare the effectiveness and adverse effects of intramuscular (IM) olanzapine and IM aripiprazole for the treatment of agitated patients with schizophrenia in clinical practice. A 24-hour randomized double-blind study carried out at a psychiatric hospital in Thailand enrolled adult patients (18-65years old) with schizophrenia experiencing agitation. Patients received one dose of IM olanzapine or IM aripiprazole followed by routine oral psychotropic medications. Efficacy was primarily measured using the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC). A total of 80 patients with a PANSS-EC score range of 22-35 entered the study, of whom 13% had a medical comorbidity and 40% a history of active substance abuse. The 40 patients receiving IM olanzapine showed greater improvement than the 40 patients receiving IM aripiprazole in PANSS-EC scores at 2h after the injection (p=0.002) but not at 24h. The two treatments were well tolerated. Patients receiving IM olanzapine experienced greater somnolence than those receiving IM aripiprazole. There were no clinically relevant changes in vital signs in either group. The results indicate that IM olanzapine and aripiprazole are similarly effective and well tolerated in the real-world treatment of agitation associated with schizophrenia over the first 24h. However, in the early hours, IM olanzapine may produce more sedation and reductions in agitation. Copyright © 2016 Elsevier B.V. All rights reserved.

    Despite advances in surgery, patients with nerve injuries frequently have functional deficits. We previously demonstrated in a rat model that daily electrical muscle stimulation (EMS) following peripheral nerve injury and repair enhances reinnervation, detectable as early as two weeks post-injury. In this study, we explain the enhanced early reinnervation observed with electrical stimulation. In two groups of rats, the tibial nerve was transected and immediately repaired. Gastrocnemius muscles were implanted with intramuscular electrodes for sham or muscle stimulation. Muscles were stimulated daily, eliciting 600 contractions for one hour/day, repeated five days per week. Sixteen days following nerve injury, muscles were assessed for functional reinnervation by motor unit number estimation methods using electromyographic recording. In a separate cohort of rats, surgical and electrical stimulation procedures were identical but muscles and distal nerve stumps were harvested for molecular analysis. We observed that stimulated muscles had significantly higher motor unit number counts. Intramuscular levels of brain-derived and glial cell line-derived neurotrophic factor (BDNF and GDNF) mRNA were significantly upregulated in muscles that underwent daily electrical stimulation compared to those without stimulation. The corresponding levels of trophic factor mRNA within the distal stump were not different from one another, indicating that the intramuscular electrical stimulus does not modulate Schwann cell-derived trophic factor transcription. Stimulation over a three-month period maintained elevated muscle-derived GDNF but not BDNF mRNA. In conclusion, EMS elevates intramuscular trophic factor mRNA levels which may explain how EMS enhances neural regeneration following nerve injury. Copyright © 2016 IBRO. Published by Elsevier Ltd.

    Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. (orig.)

    OBJECTIVE Smoking decreases insulin action and increases the risk of type 2 diabetes in humans. Mechanisms responsible for smoking-induced insulin resistance are unclear. We hypothesized smokers would have increased intramuscular triglyceride (IMTG) and diacylglycerol (DAG) concentration and decreased fractional synthesis rate (FSR) compared with nonsmokers.

    Because the hepatic portal system may not be the optimal site for islet transplantation, several extrahepatic sites have been studied. Here, we examine an intramuscular transplantation site, bioengineered to better support islet neovascularization, engraftment, and survival, and we demonstrate that at this novel site, grafted beta cell mass may be quantitated in a real-time noninvasive manner by positron emission tomography (PET) imaging. Streptozotocin-induced rats were pretreated intramuscularly with a biocompatible angiogenic scaffold received syngeneic islet transplants 2 weeks later. The recipients were monitored serially by blood glucose and glucose tolerance measurements and by PET imaging of the transplant site with [11C] dihydrotetrabenazine. Parallel histopathologic evaluation of the grafts was performed using insulin staining and evaluation of microvasularity. Reversal of hyperglycemia by islet transplantation was most successful in recipients pretreated with bioscaffolds containing angiogenic factors when compared with those who received no bioscaffolds or bioscaffolds not treated with angiogenic factors. PET imaging with [11C] dihydrotetrabenazine, insulin staining, and microvascular density patterns were consistent with islet survival, increased levels of angiogenesis, and with reversal of hyperglycemia. Induction of increased neovascularization at an intramuscular site significantly improves islet transplant engraftment and survival compared with controls. The use of a nonhepatic transplant site may avoid intrahepatic complications and permit the use of PET imaging to measure and follow transplanted beta cell mass in real time. These findings have important implications for effective islet implantation outside of the liver and offer promising possibilities for improving islet survival, monitoring, and even prevention of islet loss.

    Full Text Available The aim of the study was to compare the development of red blood cell indices after subcutaneous versus intramuscular administration of iron dextran to suckling piglets during early postnatal period. The piglets in group I (n = 17 were injected subcutaneously (into groin with 200 mg Fe3+ as iron dextran on day 3 of life. In group II (n = 16, the piglets received intramuscular injection (into gluteal muscles of 200 mg Fe3+ as iron dextran on day 3 of life. In group III (n = 10, the piglets did not receive any iron till the age of 3 days. The blood was taken and analyzed (Hb, PCV, RBC, MCV, MCH, MCHC, Fe on days 3, 7, 14, 21, 28 and 35. Haematological indices of piglets in group III were characteristic for hypochromic anaemia. Anaemia in group III had a detrimental effect on the growth rate of piglets. The development of red blood cell indices and iron concentration in blood plasma in subcutaneously treated piglets did not differ significantly from that of intramuscularly-treated group. Both treatments prevented development of anaemia.

    1989-01-01

    Twelve-hour scheduling has been a mainstay of the petrochemical industry, is common in the papermill industry, and is relatively new to the nuclear utility industry. A review of industry experiences, research, and a federal Nuclear Regulatory Commission (NRC) study of the 12-hour shift (NUREG/CR-4248) demonstrate that the advantages outweigh the disadvantages. The primary advantages are greater job satisfaction, fewer errors, and the better communications inherent in two shift turnovers versus three. Several companies that implemented the 12-hour shift found an increase in employee morale, no adverse effect on worker health, and no decline in safety. They experienced greater productivity, fewer operator errors, and better communication

    To compare the effectiveness of per rectal misoprostol over oxytocin in primary postpartum haemorrhage (PPH). Randomised controlled trial study. Gynaecology and Obstetrics Department, Unit IV, Bolan Medical Complex Hospital, Quetta, from September 2013 to February 2014. Emergency obstetric patients receiving per rectal misoprostol (800 µgm) were named as group 'A' and those receiving 10 units oxytocin intramuscularly were labelled as group 'B'. The patients were followed within 24 hours of spontaneous vaginal deliveries. Pads soaked were used to assess the amount of blood loss. A total of 1,678 patients were included in the study. The mean age of patients in group-A was 29.11 years while the mean age of patients in group-B was 29.16 years. One hundred and twenty-three (14.66%) patients in group-A and 120 (14.31%) patients in group-B had PPH. Among the total 1,678 patients, 243 (14.49%) had postpartum haemorrhage among whom 24 (9.88%) had major haemorrhage with a blood loss ≥1000 mL. Among the sub-group (839 patients) administered misoprostol had 123 (14.66%) patients with blood loss greater than 500 mL and the rest 716 patients (85.34%) had blood loss less than 500 mL. The sub-group administered oxytocin have 120 (14.31%) out of 839 patients with postpartum haemorrhage while 719 (85.69%) had blood loss less than 500 mL. Active management of 3rd stage of labour with per rectal misoprostol administration was as effective as intramuscular oxytocin. Both were equally effective to reduce PPH and the subsequent need for surgical interventions.

    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.

    Agitation is frequent in the acute psychiatric setting. The observation and treatment of agitation is important to avoid harm to patients or staff, to reduce distress of the patient, and to reduce the risk of coercion, especially physical restraint. To evaluate the effect of intramuscular treatment with psychotropics on agitation in a non-selected acute psychiatric population. The Positive and Negative Syndrome Scale Excitement Component (PANSS-EC) was implemented in the acute psychiatric ward at Psychiatric Center Copenhagen to improve assessment and treatment of agitation. During a period of almost ~2 years the staff was requested to assess agitation before and after administration of intramuscular injections. PANSS-EC was obtained at baseline and within 2 hours after injection for 135 injections with antipsychotics or benzodiazepines administered to 101 acute, non-selected psychiatric patients with high occurrence of co-morbid substance abuse. Mean PANSS-EC at baseline was 26.53 ± 4.87, and mean reduction in PANSS-EC was 14.99 ± 8.48 (p patients were subjected to physical restraint. Patients subjected to restraint had a significantly higher PANSS-EC score. Patients who received a subsequent injection had a significantly lower decline in PANSS-EC score. Besides two cases of acute dystonia following haloperidol injections, no serious side-effects were observed. Treatment of agitation with intramuscular injections of psychotropics was in general effective in this non-selected, highly agitated psychiatric population, and injections were well tolerated.

  14. In vitro simulation of distribution processes following intramuscular injection

    Full Text Available There is an urgent need for in vitro dissolution test setups for intramuscularly applied dosage forms. Especially biorelevant methods are needed to predict the in vivo behavior of newly developed dosage forms in a realistic way. There is a lack of knowledge regarding critical in vivo parameters influencing the release and absorption behavior of an intramuscularly applied drug. In the presented work the focus was set on the simulation of blood perfusion and muscle tissue. A solid agarose gel, being incorporated in an open-pored foam, was used to mimic the gel phase of muscle tissue and implemented in a flow through cell. An aqueous solution of fluorescein sodium was injected. Compared to recently obtained in vivo results the distribution of the model substance was very slow. Furthermore an agarose gel of lower viscosity an open-pored foam and phosphate buffer saline pH 7.4 were implemented in a multi-channel-ceramic membrane serving as a holder for the muscle imitating material. Blood simulating release medium was perfused through the ceramic membrane including filling materials. Transport of the dissolved fluorescein sodium was, in case of the gel, not only determined by diffusion but also by convective transport processes. The more realistic the muscle simulating materials were constituted the less reproducible results were obtained with the designed test setups.

    Intramuscular (IM) antipsychotics are preferred for efficient control of agitation symptoms. Previous studies have demonstrated that IM ziprasidone is efficacious and safe for treatment of agitation in schizophrenia. However, clinicians now recognize that racial differences may contribute to altered therapeutic response and tolerability. This study compared the efficacy and tolerability of IM ziprasidone versus IM haloperidol for the management of agitation in Chinese subjects with schizophrenia. Subjects with acute schizophrenia were randomized to either ziprasidone (n = 189, 10 to 20 mg as required up to a maximum of 40 mg/d) or haloperidol (n = 187, 5 mg every 4 to 8 hours to a maximum of 20 mg/d) for 3 days. Psychiatric assessments and adverse events were assessed at baseline, 2, 4, 24, 48, and 72 hours. In the ziprasidone group, 2.1% of subjects discontinued versus 3.7% in the haloperidol group. The least squares mean change (SE) from baseline to 72 hours in Brief Psychiatry Rating Scale total score was -17.32 (0.7) for ziprasidone (n = 167) and -18.44 (0.7) for haloperidol (n = 152), with a 95% confidence interval treatment difference of -0.7 to 2.9. Fewer subjects experienced adverse events after ziprasidone (n = 54, 28.6%) than haloperidol (n = 116, 62.0%), with a notably higher incidence of extrapyramidal symptoms in the haloperidol group (n = 69, 36.9%) compared to the ziprasidone group (n = 4, 2.1%). For controlling agitation in schizophrenia in this Chinese study, ziprasidone had a favorable tolerability profile and comparable efficacy and safety compared to haloperidol.

    Objective. To analyze the findings of intramuscular vascular malformations of an extremity on MR imaging and to correlate these findings with histopathologic examination.Design and patients. The findings on MR imaging and the medical records of 14 patients with an intramuscular vascular malformation of the extremity were retrospectively studied. All patients underwent surgical excision. Diagnoses were based on the results of pathologic examination. Findings on MR imaging were noted and correlated with the histopathologic findings.Results. Intramuscular vascular malformations of an extremity showed multi-septate, honeycomb, or mixed appearance on MR imaging. Multi-septate areas correlated with dilated and communicating vascular spaces with flattened endothelium. Honeycomb areas corresponded to vascular spaces with inconspicuous small lumina and thickened vascular walls. Areas of increased signal intensity on T2-weighted images were found in all intramuscular vascular malformations. Infiltrative margins were more commonly seen in intramuscular lymphaticovenous malformations. Adherence to neurovascular structures and orientation of the lesion along the long axis of the affected muscle were more commonly seen in intramuscular venous malformations.Conclusions. Intramuscular vascular malformations showed either a multi-septate, honeycomb, or mixed appearance, reflecting the size of the vascular spaces and the thickness of the smooth muscles of the vessel walls. Prediction of the subtype of an intramuscular vascular malformation of an extremity on MR imaging seems to be difficult, although there are associated findings that may be helpful in the differential diagnosis of each subtype.

    Hayes, Ariel; Russ, Mark J

    2016-03-01

    This study examined the impact of eliminating intramuscular PRN medication for agitation on patient and staff safety in an acute psychiatric inpatient setting. The current retrospective chart review investigated the use of PRN medications (oral and intramuscular) to treat acute agitation, including aggression, and related outcomes before and after a mandated change in PRN practice that required real time physician input before administration of intramuscular medications. The use of both oral and intramuscular PRN medications dramatically decreased following implementation of the mandated change in practice. In particular, the use of intramuscular PRNs for agitation decreased by about half. Despite this decrease, the assault rate in the hospital was unchanged, and the utilization of restraint and seclusion continued to decrease. It is possible to reduce the utilization of PRN medications for agitation without broadly compromising safety on acute care psychiatric inpatient units.

    Diaphragm pacing (DP) has been shown to successfully replace mechanical ventilators for adult tetraplegic patients with chronic respiratory insufficiency. This is the first report of DP in ventilator-dependent children. This was a prospective interventional experience under institutional review board approval. Diaphragm pacing involves outpatient laparoscopic diaphragm motor point mapping to identify the site where stimulation causes maximum diaphragm contraction with implantation of 4 percutaneous intramuscular electrodes. Diaphragm conditioning ensues to wean the child from the ventilator. Six children were successfully implanted ranging from 5 to 17 years old with the smallest 15 kg in weight. Length of time on mechanical ventilation ranged from 11 days to 7.6 years with an average of 3.2 years. In all patients, DP provided tidal volumes above basal needs. Five of the patients underwent a home-based weaning program, whereas one patient who was implanted only 11 days post spinal cord injury never returned to the ventilator with DP use. Another patient was weaned from the ventilator full time but died of complications of his underlying brain stem tumor. The remaining patients weaned from the ventilator for over 14 hours a day and/or are actively conditioning their diaphragms. Diaphragm pacing successfully replaced mechanical ventilators, which improves quality of life. Copyright © 2011 Elsevier Inc. All rights reserved.

  9. Streptococcus bovis/S. equinus complex septicemia in a group of calves following intramuscular vaccination.

    2016-07-01

    Organisms previously classified as Streptococcus bovis (i.e., the S. bovis/S. equinus complex) are common in cattle feces, but may also act as opportunistic pathogens. In the current work, Streptococcus infantarius subsp. coli, a member of this complex, was associated of a cluster of calves that died within hours of injection with a modified live viral vaccine. Within 12 h of vaccination of 46 calves at a cow/calf operation, 4 calves had died, 3 calves were ill, and 1 unvaccinated cow was dead. Autopsies were performed on the cow, 2 dead calves, and 1 affected surviving calf, which was euthanized ~24 h after vaccine administration. The animals had similar gross anatomic and microscopic lesions, including subcutaneous and intramuscular dark hemorrhage on the caudal neck, multiorgan ecchymosis and petechiation, and alveolitis to interstitial pneumonia. Gram-positive cocci were in the vasculature of the lung and skeletal muscle, and S. infantarius subsp. coli was cultured from tissues and from the vaccines used on affected animals, but not in vials used on unaffected animals. Together, these findings suggest death caused by streptococcal septicemia and toxemia as a result of contamination. © 2016 The Author(s).

    Efficacy Safety Score (ESS) with "call-out algorithm" developed in Kongsberg hospital, Norway was used for the validation. ESS consists of the mathematical sum ofscorefrom: 2 subjective (Visual Analog Scale: VAS at rest and during mobilization) and 4 vital (conscious levels, PONV circulation and respiration status) parameters and ESS > 10 is a "call-out alarm "for visit ofpatient by anaesthesiologist. Hourly registration of ESS, mobility degree and amounts of analgetics during the first 8 hours after surgery was recorded in the specially designed IPad program. According to the type ofanaesthesia all patients were allocated in 4 groups: I spinal anaesthesia (SA), II general anesthesia (GA), III peripheral blockade (PB) and IV Total intravenous anaesthesia (TIVA). A total of 223 patients were included in the study. Statistically low levels of both VAS and ESS in the first 2-4 postoperative hours were found in SA and PB groups compared to GA and TIVA groups. During 8 post-operative hours, VAS> 3 was recorded in 10.5% of SA, 13.9% in GA, 12.8% in PG and 23.5% in TIVA patients. Intramuscular postoperative analgesia was effective in SA, GA and PG groups. More attention of anaesthesiologist must be paid to patients ofter TIVA.

    Alfaxalone is a neuroactive steroid derivative of pregnanedione that was recently reintroduced to the market for use as an induction agent in small animal anaesthesia. The aim of this study was to determine an intramuscular alfaxalone dose for safe immobilisation. Ten healthy New Zealand white rabbits were used to evaluate a single intramuscular injection of alfaxalone. The design of the study was a three-way, complete block, cross-over trial to compare the effect of alfaxalone at three doses (4, 6 and 8 mg). The mean duration of the effect for the 4, 6 and 8 mg/kg doses was, respectively, 36.9 (95% CI (31.6 to 42.3)), 51.8 (46.4 to 57.2) and 58.4 (52.8 to 63.9) minutes. The loss of the righting reflex was achieved after 3.1 (2.5 to 3.8), 2.4 (1.7 to 3.1) and 2.3 (1.6 to 2.9) minutes, respectively. The mean duration of the effect for the 6 and 8 mg doses was significantly higher than for the 4 mg dose (with estimated differences of 14.8 95% CI (8.8 to 20.8) minutes and 21.4 (15.3 to 27.6) minutes, respectively). No significant dose effect was observed before the loss of the righting reflex (P=0.14). Ear pinching and limb withdrawal were elicited in all groups at every dose. Doses of 4 or 6 mg/kg could be recommended; higher doses do not provide clinical benefits and can be associated with anaesthetic complication. British Veterinary Association.

    First, we review a result in our previous paper, of how a ten-dimensional superparticle, taken off-shell, has a hidden eleven-dimensional super Poincare symmetry. Then, we show that the physical sector is defined by three first-class constraints which preserve the full eleven-dimensional symmetry. Applying the same concepts to the eleven-dimensional superparticle, taken off-shell, we discover a hidden twelve-dimensional super Poincare symmetry that governs the theory

  17. INFLUENCE OF GENETIC POLYMORPHISM IN FABP3 AND LEPR GENES ON INTRAMUSCULAR FAT CONTENT IN PIG CARCASSES

    Directory of Open Access Journals (Sweden)

    Kristina Budimir

    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.

    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

    Full Text Available Background & Objective: Administration of anesthetic substances to chickens requires careful consideration for the safe delivery of the agent to the bird. 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.

  5. Are nursing students safe when choosing gluteal intramuscular injection locations?

    Nurses are required to perform gluteal intramuscular (IM) injections in practice. There are dangers associated with erroneous performance of this task, particularly with dorsogluteal injections. Knowledge regarding safe injection practice is therefore vital for nursing students. Fifty-eight second year students at a New Zealand Nursing School were given schematic drawings of the posterior and lateral aspects of the gluteal region. They were asked to mark and justify the safest location for gluteal IM injections. Fifty-seven students marked the dorsal schematic and one the lateral, with 38 (66.7%) marking in the upper outer quadrant (UOQ). Twenty indicating the UOQ (52.6%) wrote 'sciatic' or 'nerve' in justifying their location. Nineteen (33.3%) marked a location outside the UOQ; nine (47.4%) of these mentioned 'sciatic' or 'nerve' as reasons for injection safety. Overall, 50% of students mentioned 'sciatic' or 'nerve' in justifying the safety of their chosen injection location. Results suggest some second year nursing students do not understand safe gluteal IM injection locations and rationale. Current teaching practices and IM injection techniques could be revisited to prepare students more effectively; this may help prevent pathologies arising from this procedure.

    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.

    Obtaining prompt vascular access in young children presenting to the emergency department (ED) is frequently both necessary and technically challenging. The objective of our study was to describe our experience using intramuscular (IM) ketamine to facilitate the placement of central venous catheters in children presenting to our ED needing vascular access in a timely fashion. We performed a retrospective medical record review of all pediatric patients central venous catheter facilitated by the use of IM ketamine. Eleven children met our inclusion criteria. Most of the children were young and medically complicated. The children ranged in age from 6 months to 8 years. The only complication identified was vomiting experienced by an 8-year-old boy. Emergency physicians successfully obtained central venous access in all subjects in the case series. The use of IM ketamine to facilitate the placement of central venous catheters in children who do not have peripheral venous access appears to be helpful. Emergency physicians may find it useful to be familiar with this use of IM ketamine.

    A procedure to quantify intramuscular fat was developed using common inexpensive laboratory equipment. Three homogenization methods of lyophilized muscle samples (Ball-mill, Grinder and Mortar) and two extraction methods (Ball-mill or Vortex) were used in turkey meat and pork. Two-hundred mg of lyophilized and homogenized samples were accurately weighed and mixed with 1.5 mL of dichloromethane-methanol (8:2) and shaken either in a Mixer Mill (MM400, Retsch Technology) or in a Vortex. The final mixture was separated by centrifugation. Solvent was evaporated under a nitrogen stream and lipid content was gravimetrically determined. Besides, it was checked that the fatty acid profile was not altered by the protocol used. Moreover, the analysis of 4 replicas from the same sample showed different variation coefficients (16-29%) for the new procedures proposed over a wide range of IMF content. The combination of Grinder and Vortex methodologies can be proposed as a simple and inexpensive alternative to previous ones. Copyright © 2015. Published by Elsevier Ltd.

    2017-01-01

    A lipoma is a slow-growing, benign tumor and is usually asymptomatic; hence, surgical intervention can often be avoided in patients with these tumors in the cervical and cranial area. Lipomas arise most commonly in the subcutaneous fat, but occasionally in muscle tissue. Intramuscular lipomas in the cervico-cranial area have rarely been reported. We describe here a patient with a large intramuscular lipoma in the deep cervical tissue. The patient experienced troublesome pain in the neck and occipital area, and surgical treatment was therefore suggested. Particularly in the cervical area, intramuscular lipomas sometimes invade the surrounding muscles and tissue layers and develop into an irregular mass, despite being benign. In addition, the cervical area has one of the most complex muscle structures. Nevertheless, surgical management of intramuscular lipoma in the cervical and cranial area is sometimes indicated, for example, in patients with clinical symptoms or masses with a tendency to grow large.

    To compare the pharmacokinetic parameters of cefuroxime lysine, a new second-generation of cephalosporin antibiotics, after intravenous (IV), intraperitoneal (IP), or intramuscular (IM) administration. Twelve male and 12 virgin female Sprague-Dawley rats, weighing from 200 to 250 g, were divided into three groups (n=4 for each gender in each group). The rats were administered a single dose (67.5 mg/kg) of cefuroxime lysine via IV bolus or IP or IM injection. Blood samples were collected and analyzed with a validated UFLC-MS/MS method. The concentration-time data were then calculated by compartmental and non-compartmental pharmacokinetic methods using DAS software. After IV, IP or IM administration, the plasma cefuroxime lysine disposition was best described by a tri-compartmental, bi-compartmental or mono-compartmental open model, respectively, with first-order elimination. The plasma concentration profiles were similar through the 3 administration routes. The distribution process was rapid after IV administration [t(1/2(d)), 0.10 ± 0.11 h vs 1.36 ± 0.65 and 1.25 ± 1.01 h]. The AUMC(0-∞) is markedly larger, and mean residence time (MRT) is greatly longer after IP administration than that in IV, or IM routes (AUMC(0-∞): 55.33 ± 20.34 vs 16.84 ± 4.85 and 36.17 ± 13.24 mg·h(2)/L; MRT: 0.93 ± 0.10 h vs 0.37 ± 0.07 h and 0.65 ± 0.05 h). The C(max) after IM injection was significantly higher than that in IP injection (73.51 ± 12.46 vs 49.09 ± 7.06 mg/L). The AUC(0-∞) in male rats were significantly higher than that in female rats after IM administration (66.38 ± 16.5 vs 44.23 ± 6.37 mg·h/L). There was no significantly sex-related difference in other pharmacokinetic parameters of cefuroxime lysine between male and female rats. Cefuroxime lysine shows quick absorption after IV injection, a long retension after IP injection, and a high C(max) after IM injection. After IM administration the AUC(0-∞) in male rats was significantly larger than that in

    To evaluate the serial ultrasonographic findings of experimental intramuscular hemorrhaging to determine if there is a correlation with the pathologic findings. An ultrasonography (US) was performed before and immediately after an intramuscular blood injection in nine rabbits. In addition, follow-up US images were obtained at 1, 4, 7, 10, 14, 21, and 28 days after the intramuscular blood injections in seven of the rabbits. The pathologic specimens, compared to the US findings on each date, and consisted of samples of left thigh muscle. A US, performed immediately after a blood injection, showed two patterns; 6 cases of hyperechoic muscle thickening and 3 cases of hyperechoic muscle thickening with extravasation between the epimysium and muscle bundle or within muscle bundle. A follow-up US showed a marked decrease in intramuscular hemorrhaging and microcalcifications, which appeared on the 4th, 7th and 10th day after the blood injection. The pathologic findings revealed several short echogenic lines in the muscular bundles which were hemosiderin. Moreover, a 28 day follow-up US revealed that the normal findings are correlated with the normal gross pathologic findings. The US findings of the intramuscular hemorrhaging, for each of the follow-up dates, in comparison to the pathologic findings, revealed a high correlation with the pathologic specimens. Consequently, a US transducer with high resolution can be considered as a helpful technique in the diagnosing and evaluating the follow-up treatment of intramuscular hemorrhaging

    Full Text Available The comparative pharmacokinetic profile of cefquinome was studied in sheep and goats following repeated intramuscular (IM administrations of 2 mg/kg body weight. Cefquinome concentrations in serum were determined by microbiological assay technique using Micrococcus luteus (ATCC 9341 as test organism. Following intramuscular injection of cefquinome in sheep and goats, the disposition curves were best described by two-compartment open model in both sheep and goats. The pharmacokinetics of cefquinome did not differ significantly between sheep and goats; similar intramuscular dose rate of cefquinome should therefore be applicable to both species. On comparing the data of serum levels of repeated intramuscular injections with first intramuscular injection, it was revealed that repeated intramuscular injections of cefquinome have cumulative effect in both species sheep and goats. The in vitro serum protein-binding tendency was 15.65% in sheep and 14.42% in goats. The serum concentrations of cefquinome along 24 h after injection in this study were exceeding the MICs of different susceptible microorganisms responsible for serious disease problems. These findings indicate successful use of cefquinome in sheep and goats.

    To compare sedation and antinociception after oral transmucosal (OTM) and intramuscular (IM) administration of a dexmedetomidine-buprenorphine combination in healthy adult cats. Randomized, 'blinded' crossover study, with 1 month washout between treatments. Six healthy neutered female cats, weighing 5.3-7.5 kg. A combination of dexmedetomidine (40 μg kg(-1) ) and buprenorphine (20 μg kg(-1) ) was administered by either the OTM (buccal cavity) or IM (quadriceps muscle) route. Sedation was measured using a numerical rating scale, at baseline and at various time points until 6 hours after treatment. At the same time points, analgesia was scored using a dynamic and interactive visual analogue scale, based on the response to an ear pinch, and by the cat's response to a mechanical stimulus exerted by a pressure rate onset device. Physiological and adverse effects were recorded, and oral pH measured. Signed rank tests were performed, with significance set at p < 0.05. Data are presented as median and range. There were no differences in sedation or antinociception scores between OTM and IM dosing at any of the time points. Nociceptive thresholds increased after both treatments but without significant difference between groups. Buccal pH remained between 8 and 8.5. Salivation was noted after OTM administration (n = 2) and vomiting after both OTM (n = 4), and IM (n = 3) dosing. In healthy adult cats, OTM administration of dexmedetomidine and buprenorphine resulted in comparable levels of sedation and antinociception to IM dosing. The OTM administration may offer an alternative route to administer this sedative-analgesic combination in cats. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    Full Text Available Progestins are useful for hormonal prevention of pregnancy in humans and animals. Progestrone and medroxy progestrone acetate are used for treatment of premenopausal syndrome and decreasing complications of estrogen therapy after menopause. Prescription of progesterone in dogs is usually done to control or delay estrus. If this drug is used at anestrous it will inhibit the gonadotropin excretion beyond the basic level and it will prevent cycle from happening again in proestrus or at the beginning of estrus progesterone will prevent ovulation. Use of progesterone is not totally safe in bitches. It can cause several problems such as cystic endometrial hyperplasia and pyrometera. In this study the effects of medroxy progestrone acetat (MPA on electrocardiographic changes are evaluated. After nutritional and environmental uniformity and other evaluations, the animals were divided into two groups with six bitches in each group. MPA was used at 10 mg/kg for the first group and 20 mg/kg for the second group. An ECG was recorded from the first group in time zero. MPA was injected intramuscularly and immediately after ECG recording and the time of injection was noted. Another ECG was recorded 0.5 and 2 hours after injection. The same process was repeated for the second group. It was observed that MPA at 20 mg/kg increased the heart rate and consequently PR interval and RR interval were decreased significantly in normal range. Also administration of drug at 10 mg/kg decreased the heart rate and increased PR interval, QT interval and RR interval significantly in normal range. It is probable that these observations are the result of MPAs dose dependent vasodilatory nature that induces the heart to exhibit compensative reactions such as increasing heart rate.

    We report new results from high precision analysis of an important BSM gauge theory with twelve massless fermion flavors in the fundamental representation of the SU(3) color gauge group. The range of the renormalized gauge coupling is extended from our earlier work [1] to probe the existence of an infrared fixed point (IRFP) in the β-function reported at two different locations, originally in [2] and at a new location in [3]. We find no evidence for the IRFP of the β-function in the extended range of the renormalized gauge coupling, in disagreement with [2,3]. New arguments to guard the existence of the IRFP remain unconvincing [4], including recent claims of an IRFP with ten massless fermion flavors [5,6] which we also rule out. Predictions of the recently completed 5-loop QCD β-function for general flavor number are discussed in this context.

    The author presents twelve reasons which show that the nuclear energy has not a place in the MDP Mechanism of Clean Development: a main loophole for the developed countries, the doubtful ''additionality'' of the nuclear, the treaty ratification is more difficult with the nuclear, the domestic energy conservation is more efficient in Europe than the nuclear development, the nuclear white elephants facing the South debts, the technology transfers are doubtful, the developing countries and the sustainable development policies are evicted from the MDP, some options are more powerful in the South, the reactors and transport networks size are unsuited, the absence of democratic control, the nuclear proliferation, the nuclear safety and the wastes.

    The treatment practices for vitamin D deficiency rickets are highly variable. Though a single intramuscular (IM) megadose of vitamin D is economical, and ensures good compliance, it poses the risk of hypervitaminosis D. This observational study was conducted to assess the duration of effect and safety of single IM megadose of cholecalciferol in the treatment of vitamin D deficiency rickets. Children younger than 14 years with rickets were enrolled. Baseline investigations included radiograph of wrists and estimation of serum calcium, phosphate, alkaline phosphatase (ALP), 25(OH) vitamin D and parathormone (PTH) levels. All children received a single IM megadose of vitamin D3. Biochemical parameters were re-evaluated at 1.5, 3 and 6 months after the megadose and the values were compared to the baseline. We enrolled 21 children, out of which nine remained under active follow-up till 6 months. Radiological evidence of rickets was present in all 21 children, 14 had hypocalcemia at the time of presentation. After IM cholecalciferol megadose, median 25 hydroxy vitamin D [25(OH)D] level remained significantly more than the baseline till 6 months after the megadose. At 1.5 months after the vitamin D megadose, three (30%) of the children were found to develop toxic levels of vitamin D (>150 ng/mL), although none had hypercalcemia or any clinical manifestation of vitamin D toxicity. At 3 months and 6 months after the megadose, 25(OH)D levels remained in the sufficient range (20-100 ng/mL) in seven out of the eight children who came for follow-up. A single IM megadose of vitamin D may be effective in significantly increasing the 25(OH)D levels for at least 6 months in children with rickets, but elevation of 25(OH)D to toxic range raises concern regarding its safety.

    Fine hourly forecast in single station weather forecast is required in many human production and life application situations. Most previous MOS (Model Output Statistics) which used a linear regression model are hard to solve nonlinear natures of the weather prediction and forecast accuracy has not been sufficient at high temporal resolution. This study is to predict the future meteorological elements including temperature, precipitation, relative humidity and wind speed in a local region over a relatively short period of time at hourly level. By means of hour-to-hour NWP (Numeral Weather Prediction)meteorological field from Forcastio (https://darksky.net/dev/docs/forecast) and real-time instrumental observation including 29 stations in Yunnan and 3 stations in Tianjin of China from June to October 2016, predictions are made of the 24-hour hour-by-hour ahead. This study presents an ensemble approach to combine the information of instrumental observation itself and NWP. Use autoregressive-moving-average (ARMA) model to predict future values of the observation time series. Put newest NWP products into the equations derived from the multiple linear regression MOS technique. Handle residual series of MOS outputs with autoregressive (AR) model for the linear property presented in time series. Due to the complexity of non-linear property of atmospheric flow, support vector machine (SVM) is also introduced . Therefore basic data quality control and cross validation makes it able to optimize the model function parameters , and do 24 hours ahead residual reduction with AR/SVM model. Results show that AR model technique is better than corresponding multi-variant MOS regression method especially at the early 4 hours when the predictor is temperature. MOS-AR combined model which is comparable to MOS-SVM model outperform than MOS. Both of their root mean square error and correlation coefficients for 2 m temperature are reduced to 1.6 degree Celsius and 0.91 respectively. The

    Full Text Available Nicolau syndrome is a rare complication of intramuscular injection that leads to local ischemic necrosis of the skin and adipose tissue. In this paper, we discuss etiologies, risk factors, and treatment options for gluteal Nicolau syndrome referring to patients treated in our hospital. Our study includes 17 women who visited our clinic with symptoms of gluteal necrosis secondary to intramuscular injection. The following variables were taken into account: injection site, drug administered, frequency of injections, the person who administered the injections, needle size, and needle tip color. Magnetic resonance images obtained in the aftermath of intramuscular injection application were carefully analyzed for presence of necrosis, cyst formation and the thickness of the gluteal fat tissue layer. Drugs that had been received in intramuscular injection were exclusively non-steroidal anti-inflammatory drugs. Mean patient BMI was 41.8 (all patients were considered as obese, and mean gluteal fat thickness was 54 mm. Standard length of needles (3.8 cm had been used in procedures. The wounds were treated with primary closure in 11 patients and with local flap therapy in 6 patients. The observed necrosis was a consequence of misplaced gluteal injection, where drugs were injected into the adipose tissue instead of the muscle due to the extreme thickness of the fat layer, on one hand, and the inappropriate length of standard needles, on the other hand. Intramuscular injection should be avoided in obese patients whenever possible: if it is necessary, proper injection technique should be used.

  11. Does insertion of intramuscular electromyographic electrodes alter motor behavior during locomotion?

    2015-06-01

    Intramuscular electromyography (EMG) is commonly used to quantify activity in the trunk musculature. However, it is unclear if the discomfort or fear of pain associated with insertion of intramuscular EMG electrodes results in altered motor behavior. This study examined whether intramuscular EMG affects locomotor speed and trunk motion, and examined the anticipated and actual pain associated with electrode insertion in healthy individuals and individuals with a history of low back pain (LBP). Before and after insertion of intramuscular electrodes into the lumbar and thoracic paraspinals, participants performed multiple repetitions of a walking turn at self-selected and controlled average speed. Low levels of anticipated and actual pain were reported in both groups. Self-selected locomotor speed was significantly increased following insertion of the electrodes. At the controlled speed, the amplitude of sagittal plane lumbo-pelvic motion decreased significantly post-insertion, but the extent of this change was the same in both groups. Lumbo-pelvic motion in the frontal and axial planes and thoraco-lumbar motion in all planes were not affected by the insertions. This study demonstrates that intramuscular EMG is an appropriate methodology to selectively quantify the activation patterns of the individual muscles in the paraspinal group, both in healthy individuals and individuals with a history of LBP.

    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.

    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.

    1989-01-01

    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.

    We describe new radial velocity and X-ray observations of extremely low-mass white dwarfs (ELM WDs, ∼0.2 M sun ) in the Sloan Digital Sky Survey Data Release 4 and the MMT Hypervelocity Star survey. We identify four new short period binaries, including two merger systems. These observations bring the total number of short period binary systems identified in our survey to 20. No main-sequence or neutron star companions are visible in the available optical photometry, radio, and X-ray data. Thus, the companions are most likely WDs. Twelve of these systems will merge within a Hubble time due to gravitational wave radiation. We have now tripled the number of known merging WD systems. We discuss the characteristics of this merger sample and potential links to underluminous supernovae, extreme helium stars, AM CVn systems, and other merger products. We provide new observational tests of the WD mass-period distribution and cooling models for ELM WDs. We also find evidence for a new formation channel for single low-mass WDs through binary mergers of two lower mass objects.

    Pilot study to examine the impact of long work hours and shift work on cognitive errors in nurses. Twelve-hour shifts are more commonly used in hospital settings and there is growing concern over the impact that extended and irregular work hours have on nurses' well-being and performance. Twenty-eight nurses working different shifts (8-hr days and 12-hr rotation) participated in this study. Nurses were assessed at the beginning of four consecutive shifts using actigraphy, a sleep diary and an after work questionnaire. Nurses working 12-hr rotations had less total sleep time and less sleep efficiency than 8-hr day nurses. Twelve-hour rotation nurses also napped more than their counterparts. There were no differences between the two groups with respect to cognitive errors. Twelve-hour rotations have a negative effect on nurses' sleep patterns. There is no evidence indicating 12-hr rotations increased errors. Nurse managers can implement specific strategies, such as greater shift work flexibility and designated quiet time, to reduce the effects of disturbed sleep patterns in nurses. © 2017 John Wiley & Sons Ltd.

    Branched-chain amino acids (BCAA) have been clearly demonstrated to have anabolic effects on muscle protein synthesis. However, little is known about their roles in the regulation of net AA fluxes across skeletal muscle in vivo. This study was aimed to investigate the effect and related mechanisms of dietary supplementation of BCAA on muscle net amino acid (AA) fluxes using the hindlimb flux model. In all fourteen 4-week-old barrows were fed reduced-protein diets with or without supplemental BCAA for 28 d. Pigs were implanted with carotid arterial, femoral arterial and venous catheters, and fed once hourly with intraarterial infusion of p-amino hippurate. Arterial and venous plasma and muscle samples were obtained for the measurement of AA, branched-chain α-keto acids (BCKA) and 3-methylhistidine (3-MH). Metabolomes of venous plasma were determined by HPLC-quadrupole time-of-flight-MS. BCAA-supplemented group showed elevated muscle net fluxes of total essential AA, non-essential AA and AA. As for individual AA, muscle net fluxes of each BCAA and their metabolites (alanine, glutamate and glutamine), along with those of histidine, methionine and several functional non-essential AA (glycine, proline and serine), were increased by BCAA supplementation. The elevated muscle net AA fluxes were associated with the increase in arterial and intramuscular concentrations of BCAA and venous metabolites including BCKA and free fatty acids, and were also related to the decrease in the intramuscular concentration of 3-MH. Correlation analysis indicated that muscle net AA fluxes are highly and positively correlated with arterial BCAA concentrations and muscle net BCKA production. In conclusion, supplementing BCAA to reduced-protein diet increases the arterial concentrations and intramuscular catabolism of BCAA, both of which would contribute to an increase of muscle net AA fluxes in young pigs.

    The understanding of the mechanisms that differ between breeds of cattle and their ability to deposit intramuscular adipose tissue is imperative to profitable beef production. Thus, the interactions among breeds, metabolic substrates and specific hormones in bovine intramuscular and subcutaneous adipose tissue were investigated. Subcutaneous and intramuscular adipose tissues were obtained from 10 Angus and 9 Santa Gertrudis steers immediately postmortem. The adipose tissues were incubated for 2 h and 48 h with and without 1 mU/ml insulin and 30 mg/ml bovine serum albumin (BSA) to measure the incorporation of 14 C-labeled acetate and glucose into lipid fractions. At the same chronological age, Angus steers had a more youthful lean maturity score, higher USDA marbling scores and higher USDA quality grades than carcasses from Santa Gertrudis steers

    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.

    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 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 of the article) 2018.

    The systemic and respiratory local immune response induced by the intradermal administration of a commercial inactivated Mycoplasma hyopneumoniae whole-cell vaccine (Porcilis(®) MHYO ID ONCE - MSD AH) in comparison with two commercial vaccines administered via the intramuscular route and a negative control (adjuvant only) was investigated. Forty conventional M. hyopneumoniae-free pigs were randomly assigned to four groups (ten animals each): Group A=intradermal administration of the test vaccine by using the needle-less IDAL(®) vaccinator at a dose of 0.2 ml; Group B=intramuscular administration of a commercially available vaccine (vaccine B); Group C=intramuscular administration of the adjuvant only (2 ml of X-solve adjuvant); Group D=intramuscular administration of a commercially available vaccine (vaccine D). Pigs were vaccinated at 28 days of age. Blood and bronchoalveolar lavage (BAL) fluid samples were collected at vaccination (blood only), 4 and 8 weeks post-vaccination. Serum and BAL fluid were tested for the presence of antibodies by ELISA test. Peripheral blood monomorphonuclear cells (PBMC) were isolated to quantify the number of IFN-γ secreting cells by ELISpot. Moreover, cytokine gene expression from the BAL fluid was performed. Total antibodies against M. hyopneumoniae and specific IgG were detected in serum of intradermally and intramuscularly (vaccine B only) vaccinated pigs at 4 and 8 weeks post-vaccination. M. hyopneumoniae specific IgA were detected in BAL fluid from vaccinated animals (Groups A and B) but not from controls and animals vaccinated with the bacterin D (padministration of an adjuvanted bacterin induces both systemic and mucosal immune responses. Moreover, the intramuscularly administered commercial vaccines each had a different ability to stimulate the immune response both systemically and locally. Copyright © 2013 Elsevier B.V.

    The purpose of the research was to conduct a survey on family poultry to obtain information on disease prevalence, feeding practices, and the management of poultry housing in twelve African countries. The survey data were collected during both the wet and dry seasons and summarised (average and standard deviation) by country, village/region, season, and survey question. The disease data results show that three (greenish/bloody diarrhoea, swollen head, and coughing) of top four reported symptoms are part of Newcastle disease's presenting signs. Chick mortality was also higher in the wet season, when there is a higher incidence of Newcastle disease. This was also supported by the individual country data in that those countries with high chick mortality data also had low hatchability in the wet season with Egypt being the only exception. The types of housing used for shelter for family poultry was quite variable and presented a challenge to determine the level of cleaning/sanitation to assist in controlling Newcastle disease. On the one hand, a large percentage of households reported never cleaning the poultry house (e.g., Cameroon, Morocco, Mauritius, and Sudan). On the other hand, 34% of the responses to housing type were either trees or other forms of housing that would be difficult to clean i.e., old car, fence, surrounding wall, etc. Obviously, these results should be closely examined when instituting control programs for Newcastle disease. The large variety of available scavenged feed without any data on intake raises the question of how to balance the ration for the flock. Family poultry scientists need to determine a method to estimate intake which could assist in determining what supplementary feed is necessary if any. This challenge may be one of the most important aspects to family poultry management because of the importance of nutrition to poultry production with the added difficulty of providing balanced nutrition in an extensive system.

    1989-01-01

    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.

    We report new results for a frequently discussed gauge theory with twelve fermion flavors in the fundamental representation of the SU(3) color gauge group. The model, controversial with respect to its conformality, is important in non-perturbative studies searching for a viable composite Higgs mechanism beyond the Standard Model (BSM). In comparison with earlier work, our new simulations apply larger volumes and probe deeper in fermion and pion masses toward the chiral limit. Investigating the controversy, we subject the model to opposite hypotheses with respect to the conformal window. In the first hypothesis, below the conformal window, we test chiral symmetry breaking (χSB) with its Goldstone spectrum, F π , the χSB condensate, and several composite hadron states as analytic functions of the fermion mass when varied in a limited range with our best effort to control finite volume effects. In the second test, for the alternate hypothesis inside the conformal window, we probe conformal behavior driven by a single anomalous mass dimension under the assumption of unbroken chiral symmetry at vanishing fermion mass. Our results at fixed gauge coupling, based on the assumptions of the two hypotheses we define, show low level of confidence in the conformal scenario with leading order scaling analysis. Relaxing the important assumption of leading mass-deformed conformality with its conformal finite size scaling would require added theoretical understanding of the scaling violation terms in the conformal analysis and a comprehensive test of its effects on the confidence level of the fits. Results for the running coupling, based on the force between static sources, and preliminary indications for the finite temperature transition are also presented. Staggered lattice fermions with stout-suppressed taste breaking are used throughout the simulations.

  8. Fibrous Myopathy as a Complication of Repeated Intramuscular Injections for Chronic Headache

    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.

    Full Text Available Oral-transmucosal (OTM drug delivery refers to noninvasive and painless administration of medical preparations through any oral cavity membrane to achieve systemic effects (Sattar et al., 2014. Regarding sedative drugs, OTM administration is very attractive in veterinary medicine, especially for patients difficult to inject and restrain (Messenger et al., 2016. This study aims to compare the pharmacokinetics of dexmedetomidine after OTM and intramuscular (IM administration combined with methadone. After obtaining Ethical Committee approval and owner’s written consent, eight dogs, were administered with dexmedetomidine (10 mg/kg and methadone (0.4 mg/kg by OTM and other 4 dogs by IM route. Blood samples were collected at prefixed times up to four hours. Dexmedetomidine was quantified by a validated HPLC-MS method. On dexmedetomidine concentrations, a pharmacokinetic analysis was carried out with a noncompartmental approach (Phoenix WinNonlin® 7.0, Pharsight, Cary, NC. Mean ± SD terminal half-lives of dexmedetomidine were 187.42 ± 109.66 and 94.78 ± 34.08 min after OTM and IM administration, respectively. Maximum serum (Cmax concentrations were 0.83 ± 0.32 and 9.09 ± 2.46 ng/mL for OTM and IM administration, respectively. Time to maximum concentration (Tmax were 44.38 ± 32.16 and 21.25±11.39 min by OTM and IM administration, respectively. Area under the curve from 0 to the last measured concentration (AUClast were 103.75 ± 30.23 and 614.87 ± 77.15 min*ng/mL for OTM and IM administration, respectively. Cmax, Tmax and AUClast values by OTM route demonstrate a lower and delayed absorption of the drug compared to IM. To complete the study, the pharmacokinetic analysis of methadone is foreseen, so as a clinical trial to compare the clinical effects of the combination of dexmedetomidine and methadone by OTM and IM administration and to establish an effective dosage of oral-transumucosal route in dogs for this association.

    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.

    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.)

  16. Weekly Intramuscular Injection of Levothyroxine following Myxoedema: A Practical Solution to an Old Crisis

    2015-01-01

    Full Text Available An 82-year-old female with known hypothyroidism was admitted to hospital after being found on the floor. On examination, she was unkempt, confused, bradycardic, hypothermic, and barely arousable. Initial biochemistry revealed a thyroid stimulating hormone (TSH of >100 mU/L and free thyroxine (FT4 level of 1.5 pmol/L which supported a diagnosis of myxoedema coma. She was resuscitated and commenced on liothyronine, levothyroxine, and hydrocortisone and some improvement was made. It became apparent that she was hiding and spitting out her oral levothyroxine including levothyroxine elixir. Given the need for prompt alternative control, we sought advice from international experts where intramuscular levothyroxine was recommended. She was managed from day 50 onwards with intramuscular levothyroxine 200 mcg once a week, which was subsequently increased to 500 mcg. Thyroid function normalized and she made continual cognitive and physical progress and was discharged to a rehabilitation hospital. Her intramuscular levothyroxine was stopped and she was subsequently restarted on oral levothyroxine, with a plan for on-going close monitoring of her thyroid function. This report highlights the potential to use intramuscular levothyroxine in individuals with severe hypothyroidism arising from poor compliance with levothyroxine treatment or other potential causes such as impaired absorption.

  20. Intramuscular dissection of a large ganglion cyst into the gastrocnemius muscle.

    2012-07-01

    Ganglion cysts are lesions resulting from the myxoid degeneration of the connective tissue associated with joint capsules and tendon sheaths. Most common around the wrist joint, ganglion cysts may be found elsewhere in the body, including in and around the knee joint. Uncommonly, ganglion cysts can present intramuscularly. Previous reports document the existence of intramuscular ganglia, often without histologic confirmation. This article describes a case of an intramuscular ganglion cyst in the medial gastrocnemius muscle of a 53-year-old woman. The patient initially presented for discomfort associated with the lesion. Examination was consistent with intramuscular cystic lesion of unknown etiology. Ultrasound and magnetic resonance imaging revealed the origin of the mass at the semimembranosus-gastrocnemius bursa. Because of its location, the mass was initially suspected to be a dissecting Baker's cyst, an uncommon but previously reported diagnosis. The patient underwent surgical excision, and examination of the intact specimen revealed a thin, fibrous, walled cyst with no lining epithelium, which was consistent with a ganglion cyst. To the authors' knowledge, this is the first report in the orthopedic literature of a ganglion cyst dissecting into the gastrocnemius muscle. Because ganglion cysts commonly require excision for definitive treatment and do not respond well to treatment measures implemented for Baker's cysts, including resection of underlying meniscal tears, the authors believe it is important for orthopedic surgeons to be able to distinguish between Baker's and other cysts associated with the knee joint, including ganglion cysts, which may require more definitive treatment.

    Occipital neuralgia (ON) is commonly characterized by a neuralgiform headache accompanied by a paroxysmal burning sensation in the dermatome area of the greater, lesser, or third occipital nerve. The authors report a rare case of ON caused by an intramuscular lipoma originating from the lesser occipital nerve.A 52-year-old man presented with sharp pain in the left postauricular area with a 3 × 2-cm palpable mass. Computed tomography revealed a mass suspiciously resembling an intramuscular lipoma within splenius muscle. In the operation field, a protruding mass causing stretching of the lesser occipital nerve was found. After complete resection, the neuralgiform headache symptom had resolved and the intramuscular lipoma was confirmed through histopathology.Previous studies on the causes of ON have reported that variation in normal anatomic structures results in nerve compression. Occipital neuralgia, however, caused by intramuscular lipomas in splenius muscles have not been previously reported, and the dramatic resolution following surgery makes it an interesting case worth reporting.

  4. Flexibility of working hours in the 24-hour society.

    2006-01-01

    The 24-hour Society undergoes an ineluctable process towards a social organisation where time constraints are no more restricting human life. The borders between working and social times are no more fixed and rigidly determined, and the value of working time changes according to the different economic and social effects you may consider. Shift and night work, irregular and flexible working hours, together with new technologies, are the milestone of this epochal passage. What are the advantages and disadvantages for the individual, the companies, and the society? What is the cost/benefit ratio in terms of health and social well-being? Coping properly with this process means avoiding a passive acceptance of it with consequent maladjustments at both individual and social level, but adopting effective preventive and compensative strategies aimed at building up a more sustainable society. Flexible working times now appear to be one of the best ways to cope with the demands of the modern life, but there are different points of view about labour and temporal 'flexibility" between employers and employees. For the former it means a prompt adaptation to market demands and technological innovations; for the latter it is a way to improve working and social life, by decreasing work constraints and increasing control and autonomy. Although it can be easily speculated that individual-based 'flexibility" should improve health and well-being, and especially satisfaction, whereas company-based flexibility" might interfere negatively, the effective consequences on health and well-being have still to be analysed properly.

  5. Differences in intramuscular vascular connections of human and dog latissimus dorsi muscles.

    1999-02-01

    Distal ischemia and necrosis of the dog latissimus dorsi muscle flap used in experimental cardiomyoplasty have been reported. However, little information on the intramuscular vascular anatomy of the dog latissimus dorsi is available. It is unclear whether there are any anatomic factors relating to the muscle flap ischemia and necrosis, and whether the dog latissimus dorsi is a suitable experimental model. To study the intramuscular vascular territories in the dog latissimus dorsi muscle, and to compare the intramuscular vasculature of the dog with that of the human, 5 fresh dog cadavers and 7 fresh human cadavers were injected with a mixture of lead oxide, gelatin, and water (200 mL/kg) through the carotid artery. Both the dog and the human latissimus dorsi muscles and neurovascular pedicles were dissected and radiographed. The intramuscular vascular anatomy of the latissimus dorsi muscles was compared. Radiographs demonstrate clearly that the pattern of latissimus dorsi intramuscular anastomoses between branches of the thoracodorsal artery and the perforators of posterior intercostal arteries in the proximal half of the muscle are different between the dog and the human. In the dog muscle, vascular connections between the thoracodorsal artery and the posterior intercostal arteries are formed by reduced-caliber choke arteries, whereas four to six true anastomoses without a change in caliber between them are found in the human muscle. The portion of the latissimus dorsi muscle supplied by the dominant thoracodorsal vascular territory was 25.9% +/- 0.3% in the dog and 23.9% +/- 0.5% in the human. For further comparison, an extended vascular territory in the latissimus dorsi muscle was demonstrated, including both the thoracodorsal territory and the posterior intercostal territories. The area of the extended vascular territory was 52% +/- 0.5% of the total muscle. The dog latissimus dorsi model may not be a perfect predictor of the behavior of the human latissimus

  6. Effect of Salted Ice Bags on Surface and Intramuscular Tissue Cooling and Rewarming Rates.

    Many researchers have investigated the effectiveness of different cryotherapy agents at decreasing intramuscular tissue temperatures. However, no one has looked at the effectiveness of adding salt to an ice bag. To compare the cooling effectiveness of different ice bags (wetted, salted cubed, and salted crushed) on cutaneous and intramuscular temperatures. Repeated-measures counterbalanced design. University research laboratory. 24 healthy participants (13 men, 11 women; age 22.46 ± 2.33 y, height 173.25 ± 9.78 cm, mass 74.51 ± 17.32 kg, subcutaneous thickness 0.63 ± 0.27 cm) with no lower-leg injuries, vascular diseases, sensitivity to cold, compromised circulation, or chronic use of NSAIDs. Ice bags made of wetted ice (2000 mL ice and 300 mL water), salted cubed ice (intervention A; 2000 mL of cubed ice and 1/2 tablespoon of salt), and salted crushed ice (intervention B; 2000 mL of crushed ice and 1/2 tablespoon of salt) were applied to the posterior gastrocnemius for 30 min. Each participant received all conditions with at least 4 d between treatments. Cutaneous and intramuscular (2 cm plus adipose thickness) temperatures of nondominant gastrocnemius were measured during a 10-min baseline period, a 30-min treatment period, and a 45-min rewarming period. Differences from baseline were observed for all treatments. The wetted-ice and salted-cubed-ice bags produced significantly lower intramuscular temperatures than the salted-crushed-ice bag. Wetted-ice bags produced the greatest temperature change for cutaneous tissues. Wetted- and salted-cubed-ice bags were equally effective at decreasing intramuscular temperature at 2 cm subadipose. Clinical practicality may favor salted-ice bags over wetted-ice bags.

    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

    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.

    Aims Multimodal analgesia is thought to produce balanced and effective postoperative pain control. A combined therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) and opiates could result in synergistic analgesia by acting through different mechanisms. Currently there are very few parenterally administered NSAIDs suitable for the immediate postoperative period. Therefore, this study was undertaken to assess the analgesic efficacy, relative potency, and safety of parenteral dexketoprofen trometamol following major orthopaedic surgery. Methods One hundred and seventy-two patients elected for prosthetic surgery, were randomized to receive two intramuscular injections (12 hourly) of either dexketoprofen 50 mg, ketoprofen 100 mg or placebo in a double-blind fashion. Postoperatively, the patient's pain was stabilized, then they were connected to a patient- controlled analgesia system (PCA) of morphine for 24 h (1 mg with 5 min lockout). Results The mean cumulative amount of morphine (CAM) used was of 39 mg in the dexketoprofen group and 45 mg in the ketoprofen group vs 64 mg in the placebo group. (Reduction in morphine use was approximately one-third between the active compounds compared with placebo (adjusted mean difference of −25 mg between dexketoprofen and placebo and −23 mg between ketoprofen and placebo. These differences were statistically significant: P ≤ 0.0003; 95% CI −35, −14. Pain-intensity scores were consistently lower with the active compounds, the lowest corresponded to the dexketoprofen-treated patients. Regarding sedation, there were statistically significant differences between the two active compounds and placebo only at the 2nd and 13th hours. Wound bleeding was specifically measured with no statistically significant differences found between all the groups. Conclusions Intramuscular administration of dexketoprofen trometamol 50 mg has good analgesic efficacy both in terms of opioid-sparing effect and control of pain after major

    Three years have passed since the countermeasures against the adverse health effects of overwork started in Japan, and fruitful outcomes have been expected. In the current study, a systematic review of articles was performed regarding the association of long working hours (LWH) with cardiovascular diseases (CVD) to obtain recent evidence of their association. An electronic database search was conducted using PubMed among English-written original articles published until December, 2004. A total of twelve articles were found conforming to the study's inclusion criteria, but evidence supporting the association of LWH and CVD was not detected. However, some distinctive studies related to the prevention of CVD were found relating to the concept of sensitive psychosocial factors such as vital exhaustion, and to the statistical modeling of occupational factors and biological indicators with the interaction term of psychosocial factors. Further studies will be needed to clarify the association of LWH and CVD.

    deficiency anemia in children. Study Design: Randomized controlled trial. Place and Duration of Study: Paediatric department of Combined Military Hospital Kharian, Pakistan, from October 2011 to March 2013. Patients and Methods: In total 200 anemic children from 6 months to 5 years of age were included. Cut off value for Hb was < 8 gm/dl. Patients were divided into two groups, each of 100, randomly. Group A received oral sodium feredetate (iron edetate) and group B received intramuscular iron sorbitol. Rise in Hb > 10 gm/dl was kept as the desired value. Maximum duration of treatment planned was 12 weeks for group A and 2 weeks for group B. Laboratory parameters such as Hb%, mean corpuscular volume (MCV), retic count and serum ferritin level were used to detect the responses in both groups at one week, two weeks, four weeks and twelve weeks of treatment. Results: Among 200 patients, male and female distribution was 45% and 55% respectively. Desired rise in Hb in group B was achieved much earlier i.e. at two weeks as compared to group A. Progressive rise in laboratory parameters was observed but this rise was more evident in group B as compared to group A. After one week treatment in group A, rise in retic count, Hb, ferritin and MCV was 0.759 ± 0.318, 0.814 ± 0.387, 0.47 ± 0.154 and 4.28 ± 2.468 respectively. But rise in these values in group B was 2.235±0.632, 2.335 ± 0.135, 6.31 ± 1.123 and 12.11 ± 0.414 respectively. Same persistent different trend was observed at 2 and 4 weeks. After 12 weeks treatment in group A, rise in retic count, Hb, ferritin and MCV was 1.044 ± 0.222, 5.204 ± 0.134, 17.39 ± 2.551 and 16.61 ± 1.214 respectively but rise in these laboratory indices in group B was 0.551 ± 0.261, 6.097 ± 0.21, 42.49 ± 2.768 and 20.68 ± 2.233 respectively. The comparison of hematological indices after 12 weeks in A and B groups show significant differences. All these parameters improved in both groups but improvement in group B was drastically

    With the aim of assessing the kinetics of a diphosphonate administered by intramuscular injection, we have studied the behaviour of sup(99m)Tc-labelled 1-hydroxy-1, 1-diphosphonate in man and in experimental animals, after intramuscular injection. The curves of plasma and urine radioactivity were analyzed in a six-compartment kinetic model containing seven transition coefficients. The results show that the diphosphonate given by intramuscular injection is absorbed rapidly and completely. Therefore the possibility of using this way of administration should be considered in the pathological conditions in which diphosphonates are used as therapeutic agents.

    The concentration of enrofloxacin in plasma, intestinal tissue, lymph nodes and intestinal contents was investigated in healthy pigs after oral (p.o.) and intramuscular (i.m.) administration of a single dose of 2.5 mg/kg bw. Tissue and content samples were collected from jejunum, ileum, caecum...... administration, and maximum concentrations in tissue and plasma were determined later than after i.m. administration. No difference between route of administration was observed in the intestinal content. Enrofloxacin concentrations in faeces during a 5-day dosing regimen with i.m. and p.o. administration were....... On the basis of these results it was concluded that in order to ensure an immediate high concentration of enrofloxacin, and thereby avoid an initial selection for resistant mutants, the intramuscular route seems to be preferable to the oral route....

    The nonsteroidal antiinflammatory drug ketoprofen (KTP) is a commonly used antiinflammatory and analgesic agent in reptile medicine, but no studies documenting its pharmacokinetics in this species have been published. Ketoprofen was administered as a racemic mixture to green iguanas (Iguana iguana) intravenously (i.v.) and intramuscularly (i.m.) at 2 mg/kg. Pharmacokinetic analyses were performed and indicated that ketoprofen in iguanas administered by the intravenous route has a classical two-compartmental distribution pattern, a slow clearance (67 ml/ kg/hr) and a long terminal half-life (31 hr) compared to ketoprofen studies reported in mammals. When delivered by the intramuscular route, bioavailability was 78%. These data indicate the daily dosing that is generally recommended for reptile patients, as an extrapolation from mammalian data, may be more frequent than necessary.

  17. Sequential decoding of intramuscular EMG signals via estimation of a Markov model.

    2014-09-01

    This paper addresses the sequential decoding of intramuscular single-channel electromyographic (EMG) signals to extract the activity of individual motor neurons. A hidden Markov model is derived from the physiological generation of the EMG signal. The EMG signal is described as a sum of several action potentials (wavelet) trains, embedded in noise. For each train, the time interval between wavelets is modeled by a process that parameters are linked to the muscular activity. The parameters of this process are estimated sequentially by a Bayes filter, along with the firing instants. The method was tested on some simulated signals and an experimental one, from which the rates of detection and classification of action potentials were above 95% with respect to the reference decomposition. The method works sequentially in time, and is the first to address the problem of intramuscular EMG decomposition online. It has potential applications for man-machine interfacing based on motor neuron activities.

    In the past, the only kind of medicines used for symptomatic treatment of space motion sickness (SMS) in space had been oral, transdermal, or suppositories. This paper describes the effect of the first intramuscular (IM) administration of Phenergan (50-mg in single dose) on SMS in one subject who exhibited grade-3 symptoms and signs which persisted unabated throughout the first and the second flight days aboard the Space Shuttle. Thirty minutes after the injection, the subject had completely recovered. His symptoms were gone, his appetite was back, and he had no recurrences for the remainder of the flight. Since that experiment, intramuscular injections have been given nine more times on subsequent flights, with similar results.

    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.

    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.

    To elucidate the intramuscular distribution and branching patterns of the abducens nerve in the lateral rectus (LR) muscle so as to provide anatomical confirmation of the presence of compartmentalization, including for use in clinical applications such as botulinum toxin injections. Thirty whole-mount human cadaver specimens were dissected and then Sihler's stain was applied. The basic dimensions of the LR and its intramuscular nerve distribution were investigated. The distances from the muscle insertion to the point at which the abducens nerve enters the LR and to the terminal nerve plexus were also measured. The LR was 46.0 mm long. The abducens nerve enters the muscle on the posterior one-third of the LR and then typically divides into a few branches (average of 1.8). This supports a segregated abducens nerve selectively innervating compartments of the LR. The intramuscular nerve distribution showed a Y-shaped ramification with root-like arborization. The intramuscular nerve course finished around the middle of the LR (24.8 mm posterior to the insertion point) to form the terminal nerve plexus. This region should be considered the optimal target site for botulinum toxin injections. We have also identified the presence of an overlapping zone and communicating nerve branches between the neighboring LR compartments. Sihler's staining is a useful technique for visualizing the entire nerve network of the LR. Improving the knowledge of the nerve distribution patterns is important not only for researchers but also clinicians to understand the functions of the LR and the diverse pathophysiology of strabismus.

    Objective We wanted to demonstrate the temporal changes of the magnetic resonance imaging (MRI) findings in experimentally-induced intramuscular hematomas in rats and to correlate these data with the concurrent pathologic observations. Materials and Methods Intramuscular hematoma was induced in 30 rats. The MR images were obtained at 1, 4, 7 and 10 days and at 2, 3, 4, 6 and 8 weeks after muscle injury. The characteristic serial MRI findings were evaluated and the relative signal intensities were calculated. Pathologic specimens were obtained at each time point. Results On the T1-weighted imaging (T1WI), the intramuscular hematomas exhibited isointensity compared to that of muscle or the development of a high signal intensity (SI) rim on day one after injury. The high SI persisted until eight weeks after injury. On the T2-weighted imaging (T2WI), the hematomas showed high SI or centrally low SI on day one after injury, and mainly high SI after four days. A dark signal rim was apparent after seven days, which was indicative of hemosiderin on the pathology. The gradient echo (GRE) imaging yielded dark signal intensities at all stages. Conclusion Unlike brain hematomas, experimentally-induced intramuscular hematomas show increased SI on both the T1WI and T2WI from the acute stage onward, and this is pathologically correlated with a rich blood supply and rapid healing response to injury in the muscle. On the T2WI and GRE imaging, high SI with a peripheral dark signal rim is apparent from seven days to the chronic stage. PMID:21228942

    Full Text Available Abstract Background Llamas (Lama glama are induced ovulators and the process of ovulation depends on dominant follicular size. In addition, a close relationship between behavioural estrus and ovulation is not registered in llamas. Therefore, the exogenous control of follicular development with hormones aims to predict the optimal time to mate. Oestradiol-17β (E2 and its esters are currently used in domestic species, including camelids, in synchronization treatments. But, in llamas, there is no reports regarding the appropriate dosages to be used and most protocols have been designed by extrapolation from those recommended for other ruminants. The aim of the present study was to characterize plasma E2 concentrations in intact female llamas following a single intramuscular (i.m. injection of two oestradiol esters: oestradiol benzoate (EB and oestradiol cypionate (ECP. Methods Twelve non pregnant and non lactating sexually mature llamas were i.m. injected on day 0 with 2.5 mg of EB (EB group, n = 6 or ECP (ECP group, n = 6. Blood samples were collected immediately before injection, at 1, 6, 12, 24 h after treatment and then daily until day 14 post injection. Changes in hormone concentrations with time were analyzed in each group by analysis of variance (ANOVA using a repeated measures (within-SS design. Plasma E2 concentrations and area under the concentration-time curve (AUC values were compared between groups by ANOVA. In all cases a Least-Significant Difference test (LSD was used to determine differences between means. Hormonal and AUC data are expressed as mean ± S.E.M.

In all cases a Least-Significant Difference test (LSD) was used to determine differences between means. Hormonal and AUC data are expressed as mean ± S.E.M. Results Peak plasma E2 concentrations were achieved earlier and were higher in EB group than in ECP group. Thereafter, E2 returned to physiological concentrations earlier in EB group (day 5) than in ECP group (day 9). Although plasma E2 profiles differed over time among groups there were no differences between them on AUC values. Conclusions The i.m. injection of a single dose of both

    Prevention of postpartum haemorrhage (PPH) is essential in the pursuit of improved health care for women. Oxytocin, the most commonly used uterotonic agent to prevent PPH, has no established the route of administration. In this study we aimed to compare whether the mode of oxytocin administration, i.e., intravenous and intramuscular administration, has an effect on the potential benefits and side effects. A total of 256 women were randomised into two groups: intramuscular group (128) or intravenous group (128). Estimated blood loss during the third stage of labour was similar between the two groups (p = 0.572). Further there were no statistically significant difference was noted between the two groups in terms of the mean duration of labor, duration of the third stage of labor, manual removal of the placenta, need for instrumental delivery, need for blood transfusion, PPH ≥500 mL, PPH ≥1000 mL, or length of hospital stay. Using oxytocin by intravenous and intramuscular route has a similar efficacy and adverse effects.

    This study aimed to develop a model for pharmacodynamic and pharmacokinetic studies of naloxone antagonism under steady-state opioid agonism and to compare a high-concentration/low-volume intranasal naloxone formulation 8 mg/ml to intramuscular 0.8 mg. Two-way crossover in 12 healthy volunteers receiving naloxone while receiving remifentanil by a target-controlled infusion for 102 min. The group were subdivided into three different doses of remifentanil. Blood samples for serum naloxone concentrations, pupillometry and heat pain threshold were measured. The relative bioavailability of intranasal to intramuscular naloxone was 0.75. Pupillometry showed difference in antagonism; the effect was significant in the data set as a whole (p < 0.001) and in all three subgroups (p < 0.02-p < 0.001). Heat pain threshold showed no statistical difference. A target-controlled infusion of remifentanil provides good conditions for studying the pharmacodynamics of naloxone, and pupillometry was a better modality than heat pain threshold. Intranasal naloxone 0.8 mg is inferior for a similar dose intramuscular. Our design may help to bridge the gap between studies in healthy volunteers and the patient population in need of naloxone for opioid overdose. clinicaltrials.gov : NCT02307721.

    Fatty acid synthase (FASN) is an enzyme involved with fat deposition and fatty acid composition in cattle. This study was conducted to detect single nucleotide polymorphisms (SNPs) of the FASN gene and explore their relationships with ultrasound carcass traits in order to assess the potential use of the FASN gene for the breeding selection of Qinchuan cattle for desirable carcass traits. The frequencies of SNP g.12740C>T, g.13192T>C and g.13232C>T were identified in 525 individual Qinchuan cattle which were also assessed for backfat depth, eye muscle area and intramuscular fat by ultrasound. According to the PIC values, g.13192T>C possessed an intermediate polymorphism (0.25T, g.12740C>T possessed low polymorphism (PICC were in Hardy-Weinberg disequilibrium (c2C was associated with a greater eye muscle area and the TT genotype at g.13232C>T was associated with greater intramuscular fat. When these genotypes were combined there was no difference in eye muscle area and intramuscular fat between the diplotypes. The H 2 H 2 diplotype was associated with carcass traits that are likely to provide economic advantage in Qinchuan cattle. Variations in the FASN genes and their corresponding genotypes may be considered as molecular markers for economic traits in cattle breeding. Copyright © 2017 Elsevier B.V. All rights reserved.

    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

    Allied health care professionals commonly apply cryotherapy as treatment for acute musculoskeletal trauma and the associated symptoms. Understanding the impact of a tape barrier on intramuscular temperature can assist in determining treatment duration for effective cryotherapy. To determine whether Kinesio® Tape acts as a barrier that affects intramuscular temperature during cryotherapy application. A repeated-measures, counterbalanced design in which the independent variable was tape application and the dependent variable was muscle temperature as measured by thermocouples placed 1 cm beneath the adipose layer. Additional covariates for robustness were BMI and adipose thickness. University research laboratory. 19 male college students with no contraindications to cryotherapy, no known sensitivity to Kinesio® Tape, and no reported quadriceps injury within the past six months. Topical cryotherapy: crushed-ice bags of 1 kg and 0.5 kg. Intramuscular temperature. The tape barrier had no statistically significant effect on muscle temperature. The pattern of temperature change was indistinguishable between participants with and without tape application. Findings suggest health care professionals can combine cryotherapy with a Kinesio® Tape application without any need for adjustments to cryotherapy duration.

    A new minimally invasive metabolic test for the diagnosis of susceptibility for malignant hyperthermia measuring intramuscular p(CO(2)) and lactate following local application of caffeine and halothane in humans was recently proposed. The present study tested the hypothesis that a more simplified test protocol allows a differentiation between malignant hyperthermia susceptible (MHS) and malignant hyperthermia nonsusceptible (MHN) and control individuals. With approval of the local ethics committee and informed consent, microdialysis and p(CO(2)) probes with attached microtubing were placed into the lateral vastus muscle of six MHS, seven MHN and seven control individuals. Following equilibration, boluses of 500 microl caffeine 80 mmol l(-1) and halothane 10 vol% dissolved in soybean oil were injected locally. p(CO(2)) and lactate were measured spectrophotometrically. The maximal rate of p(CO(2)) increase was significantly higher in MHS than in MHN and control individuals following application of halothane and caffeine, respectively. Intramuscular caffeine injection leads to a significantly higher increase of local lactate levels in MHS than in MHN and control individuals, whereas halothane increased local lactate levels in all investigated groups. Haemodynamic and systemic metabolic parameters did not differ between the investigated groups. Local caffeine and halothane injection increased intramuscular metabolism in MHS individuals significantly more than in the two other groups. In contrast to previous investigations, direct injection of the concentrations of halothane described here increased lactate and p(CO(2)) even in MHN skeletal muscle.

    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.

    The objective of this work was to demonstrate that the New Zealand White (NZW) rabbit intramuscular model can be used for detecting calcification in bioprosthetic tissue and to compare the calcification in the rabbit to that of native human valves. The rabbit model was compared with the commonly used Sprague–Dawley rat subcutaneous model. Eighteen rabbits and 18 rats were used to assess calcification in bioprosthetic tissue over time (7, 14, 30, and 90 d). The explanted rabbit and rat tissue discs were measured for calcium by using atomic absorption and Raman spectroscopy. Calcium deposits on the human valve explants were assessed by using Raman spectroscopy. The results showed that the NZW rabbit model is robust for detecting calcification in a shorter duration (14 d), with less infection complications, more space to implant tissue groups (thereby reducing animal use numbers), and a more metabolically and mechanically dynamic environment than the rat subcutaneous model . The human explanted valves and rabbit explanted tissue both showed Raman peaks at 960 cm−1 which is representative of hydroxyapatite. Hydroxyapatite is the final calcium and phosphate species in the calcification of bioprosthetic heart valves and rabbit intramuscular implants. The NZW rabbit intramuscular model is an effective model for assessing calcification in bioprosthetic tissue. PMID:19619417

    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. © Georg Thieme Verlag KG Stuttgart · New York.

    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.

    The medial sural artery perforator (MSAP) flap is a versatile fasciocutaneous flap. The main difficulty encountered when raising the MSAP flap is in obtaining adequate pedicle length during intra-muscular dissection. The objective of this study was to determine the pattern of intra-muscular course of the MSAP flap pedicle. 14 cadaveric specimens were dissected and CT angiograms of 84 legs were examined. The intra-muscular branching pattern and depths of the medial sural artery branches were analyzed. The number of perforators, position of the dominant perforator and both intra-muscular and total pedicle length were also recorded and compared to existing anatomical data. Three types of arterial branching pattern were identified within the medial gastrocnemius, demonstrating one (31%), two (59%) or three or more (10%) main branches. A dominant perforator from the medial sural artery was present in 92% of anatomical specimens (13/14). Vertically, the location of the perforator from the popliteal crease was on average 13 cm (±2 cm). Transversely, the perforator originated 2.5 cm (±1 cm) from the posterior midline. Using CT angiography it was possible in 10 consecutive patients to identify a more superficial intra-muscular branch and determine the leg with the optimal branching pattern type for flap harvest. This study is the first to describe the variability of the intra-muscular arterial anatomy of the medial head of gastrocnemius muscle. Surgeons utilizing the MSAP flap option should be aware of the possible branching pattern types and consequently the differing perforator distribution and depths of intra-muscular branches. Routine use of pre-operative CT angiogram may help determine which leg has the most favorable branching pattern type and intra-muscular course for flap harvest.

    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.

    Full Text Available Twenty goats which served as the experimental group were administered ascorbic acid (AA per os at a dosage rate of 100 mg/kg body mass, while 20 others served as controls and were given 10 mt each of sterile water. Forty minutes after the administration and loading, the goats were transported for 12 h. Handling and loading of the experimental and control groups of goats decreased (P < 0.05 the potassium and sodium serum concentrations. The concentration of serum chloride, sodium and calcium increased significantly (P< 0.05 immediately post-transportation, while potassium and magnesium decreased (P < 0.05 in the control goats. In AA-treated goats sodium and magnesium concentrations decreased abruptly (P< 0.05, while calcium increased significantly (P< 0.05 after transportation. Handling, loading and transportation adversely affected the electrolyte balance of the goats which suggested respiratory alkalosis, dehydration and muscular damage in the transported goats, and the administration of AA alleviated the adverse effects of road transportation stress on serum electrolytes.

    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...

    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.

And what happens if there is a misalignment between actual hours worked and preferred hours, the so-called work hours constraints? How does this affect the productivity of workers, their health, and overall life satisfaction? Labor supply and corresponding demand are fundamental to production. Labor economists know for long t...

    Full Text Available Background: Patients with acute renal colic usually require immediate diagnosis and treatment. In this clinical trial analgesic effect of hyoscine N-butyl bromide and desmopressin combination in comparison with hyoscine N-butyl bromide alone in patients with acute renal colic induced by urinary stones was assessed. Methods: The study included 114 patients randomly allocated in two groups (A and B. Patients in group A received 20 mg intramuscular hyoscine N-butyl bromide at admission time and patients in group B received 20 μg of intranasal desmopressin in combination with 20 mg intramuscular hyoscine N-butyl bromide. A visual analogue scale (VAS; a 10-cm horizontal scale ranging from "zero or no pain" to "10 or unbearable pain" was hired to assess the patients′ pain severity at baseline, 30 and 60 minutes after the treatments. Results: On admission, the pain level was similar in both groups (group A: 8.95 ± 0.11 and group B: 8.95 ± 0.12. In group A, the mean of pain level showed a decrease after 30 minutes (group A: 7.26 ± 0.25 and group B: 5.95 ± 0.28 but further decreasing did not occur; however in group B, the pain consistently decreased and the mean after 60 minutes was significantly decreased (group A: 6.80 ± 0.31 and group B: 3.71 ± 0.31. No side effects were detected in this study. Conclusions: The combination of hyoscine N-butyl bromide and desmopressin is more effective than hyoscine N-butyl bromide alone in patients with renal colic. Further studies are recommended to validate these findings and compare the different doses of desmopressin.

    Previous research hypothesizes that long working hours are related to consumerism, the ideal worker norm, high levels of human capital, and a high cost-of-job-loss. The authors test these hypotheses using panel data on working hours for an Australian sample of full-time employed workers. Analyses include a static cross-sectional model and a persistence model for long hours over time. The results suggest that long hours (50 or more hours in a usual week) are often persistent, and provide stron...

    were arranged at a time convenient for the participants. All participants were given information sheets prior to interviews, and participants were asked to sign consent forms before the interviews commenced. These forms were provided in Tongan and English versions. Most of the interviews ranged between one to three hours. Interviews were audiotaped, and confidentiality was maintained throughout the research. Twelve men were interviewed. All participants were Tongan men born and raised in Tonga. The ages of men ranged between 30 and 75 years. Most of the men had been residing in New Zealand for over 30 years, although some men had only been in New Zealand between 2-18 years. Most of the men were employed and a few had retired from work. Most of these men also belonged to a church. All of the men who participated were married.

    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.

    1,1'-Methylenebis[4-[(hydroxyimino)methyl]-pyridinium] dimethanesulfonate (MMB4 DMS) is currently under development for the treatment of chemical warfare organophosphorus nerve agent poisoning. The present study evaluates the absorption, distribution, metabolism, and excretion of (14)C-MMB4 DMS administered intramuscularly to rats and rabbits. The formulated mixture of radiolabeled and nonradiolabeled MMB4 DMS was administered as a single or 7-day repeated dose. Rat doses were 55 or 220 mg/kg (100 µCi/kg), and rabbit doses were 25 or 100 mg/kg (31.25 and 62.5 µCi/kg, respectively). Urine, bile (rats only), feces, blood, and tissues were collected for up to 72 hours. Metabolic profiling using high-performance liquid chromatography with radiodetection was performed on selected urine samples. For both animal species, the majority of the total radioactivity was excreted in the urine (74%-94%) by 72 hours after dosing with greater than 90% of the radioactivity measured in the urine within 8 to 12 hours after dosing. There were no apparent species or dose differences in the urine excretion pattern. The distribution of (14)C-MMB4 DMS-derived radioactivity was rapid and generally reached the highest concentration by the first collection time point (0.25 hours). The tissue-blood concentration ratios were highest at the injection sites and in the kidneys and gastrointestinal tract contents for both the species. Two metabolites of MMB4 DMS were detected in rat and rabbit urine; their structure was confirmed by liquid chromatography with tandem mass spectrometry as 4-pyridine aldoxime and isonicotinic acid (pyridine-4-carboxylic acid).

  7. Intramuscular diclofenac vs periprostatic lidocaine injection for controlling pain undergoing transrectal ultrasound guided prostatic biopsy

    International Nuclear Information System (INIS)

    Alam, S.I.

    2017-01-01

    Background: Transrectal ultrasound (TRUS) technique for getting prostatic tissue for histopathology is now the standard procedure for malignant lesions of the prostate and imperative diagnostic investigation of patients with clinical specks of prostatic neoplasia. During TRUS guided biopsy, pain control has been important issue therefore, highly potent analgesia before this procedure should be considered on high priority according to current census. Therefore, we compared intramuscular diclofenac injection with sensory blockade of injection lidocaine to abolish pain undergoing prostatic biopsy with TRUS technique. Methods: Total 200 patients were selected for this study having raised PSA values and suspicious nodule on Digital Rectal Examination. These patients were segregated into two groups by randomization. Group Ar eceived intramuscular diclofenac and group Bw ere infiltrated with lidocaine injection for sensory blockade. Results: Patients in group A was having mean age of 64.5±5.8 years while for group B patients was 65.6±4.9 years (p=0.16). Both groups have statistically insignificant difference in their mean PSA values (p=0.24) and mean prostatic volume (p=0.22). The mean pain scores on visual analogue scale in groups A was 3.5±0.8 and in group B it was 2.4±0.8 (p<0.001). 60% group A patients reported with mild or no pain compared to 90% in group B. (p<0.001). Conclusion: Local blockade with lidocaine injection has better pain control as compared to patients experienced pain with intramuscular diclofenac used for prostatic biopsy through TRUS technique.

  8. Real-time simultaneous and proportional myoelectric control using intramuscular EMG

    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.

  9. Computed tomographic measurement of gluteal subcutaneous fat thickness in reference to failure of gluteal intramuscular injections

    Casual observation of gluteal region fat thickness on computed tomography (CT) of the pelvis leads to the hypothesis that, in some individuals intended intramuscular injections are not properly deposited in the gluteal muscle. We gathered and analyzed data to determine whether this hypothesis was true. CT scans of the pelvis were analyzed over an 18-day period in the tall of 2005. The thickness of gluteal region subcutaneous fat was measured in a standardized manner. Measurement of gluteal region subcutaneous fat thickness was performed for 298 pelvic CT scans. There were 150 male subjects and 148 female subjects. The average gluteal fat thickness for female subjects was 33.2 mm, whereas the average for male subjects was 23.1 mm. Analysis revealed a significant difference in gluteal region fat thickness between male and female subjects. A 37-mm needle, allowing for 6-mm penetration of the gluteal muscle, would not have entered the gluteal muscle fibres in 81 of 148 female subjects (54.7%), in 21 of 150 male subjects (14%), and in 102 of the 298 total sample (34.2%). Analysis revealed a significant difference between male and female subjects with regard to gluteal muscle needle penetration. An overall predicted failure rate of 34% was identified for intended gluteal intramuscular injections when the standard technique was used. This is important information for care providers who inject medications in the gluteal region. In a significant number of patients, the medications will be injected subcutaneously and not into the gluteal musculature, possibly altering the pharmacokinetics of the administered medication. An alternative injection site should probably be chosen to increase the success rate of intramuscular deposition of medications and vaccines in unselected adults. (author)

    The two most commonly used strategies to evaluate dialysis patients' blood pressure (BP) level are 44-hour and 24-hour ambulatory blood pressure monitoring (ABPM). The objective of this study was to find an appropriate 24-hour period that correlated well with the 44-hour BP level and determine the differences between these strategies. In a group of 51 dialysis patients, the authors performed 44-hour ABPM and extracted data for a fixed 24-hour ABPM. The fixed 24-hour ABPM started at 6 am on the nondialysis day. A strong correlation was found between all parameters of 44-hour and the fixed 24-hour ABPM, with paired sample t test showing only small magnitude changes in a few parameters. Both 24-hour ABPM and 44-hour ABPM were superior to clinic BP in predicting left ventricular mass index (LVMI) by multiple regression analysis. It was found that 44-hour ambulatory arterial stiffness index (AASI), but not 24-hour AASI, had a positive association with LVMI (r=0.328, P=.021). However, after adjustment for 44-hour systolic blood pressure, this association disappeared. Fixed 24-hour ABPM is a good surrogate of 44-hour ABPM to some extent, while 44-hour ABPM can provide more accurate and detailed information. ©2013 Wiley Periodicals, Inc.

    We herein report a rare case of giant intramuscular lipoma of the tongue. A 75-year-old Italian male presented at our department with a large tumor at the tip of the tongue that had been present for over 30 years. Clinical examination revealed a yellowish lesion, measuring 10 cm in maximum diameter, protruding from lingual surface. Histological examination showed an unencapsulated lipomatous tumor composed of mature adipocytes, uniform in size and shape, diffusely infiltrating striated muscle fibers of the tongue. The patient is well with no local recurrence after a 15-month follow-up period.

    Full text: Heavy metals become toxic when they are not metabolized by the body and accumulate in soft tissues. These metals may enter the body through food, water, air or absorption through skin when an individual is exposed to areas with high heavy metal content such as agriculture, pharmaceutical manufacturing, paint and heavy metal industries or residential settings. Majority of population commonly get affected by heavy metal poisoning. Heavy metal poisoning is more likely to result through inhalation or ingestion route. Aim of the present study is to provide an easy, effective and controlled chelating therapy against heavy metal using Ca-disodium EDTA intramuscular injection. Ca-disodium-EDTA and Sesame oil were procured from Merck, India and Sigma Aldrich, USA respectively. Ca-Na 2 EDTA radiolabeling with 99m Tc-pertechnetate was standardized using stannous ions as reducing agent. The hypothesis of present work is to maintain effective concentration of chelating agent in blood for prolong time period. To test this hypothesis, we studied 1% Ca-Na 2 EDTA blood bioavailability after intramuscular depot administration in new zealand white rabbit. The optimized radiolabeled intramuscular formulation was evaluated for its dissolution and permeation studies in isotonic buffer solution were envisaged through radiometry. Sub-acute toxicity studies were performed after a single dose intramuscular administration of 1% Ca-Na 2 EDTA in Sprague Dawley rats. Radiolabeled Ca-disodium-EDTA (>95% labeled) was found to be fairly stable up to 24 h in physiological solution (Serum) as well as in normal saline with negligible degradation of 2.5% and 5.0% respectively, thereby indicating high stability of radiolabeled product. In-vitro data indicates that control release pattern (Cmax 24 hrs) with effective concentration up to seven days. 99m Tc-CaNa 2 EDTA retention at depot site was estimated up to 3 days by scintigraphy.

    Intramuscular pressure (IMP) and electromyography (EMG) mirror muscle force in the nonfatigued muscle during static contractions. The present study explores whether the constant IMP-EMG relationship with increased force may be extended to dynamic contractions and to fatigued muscle. IMP and EMG...... with speed of abduction. In the nonfatigued supraspinatus muscle, a linear relationship was found between IMP and EMG; in contrast, during fatigue and recovery, significant timewise changes of the IMP-to-EMG ratio occurred. The results indicate that IMP should be included along with EMG when mechanical load...... sharing between muscles is evaluated during dynamic and fatiguing contractions....

    2017-07-01

    Knee flexion contracture (KFC) is a common complication of recurrent hemarthrosis in children and young adults with hemophilia. If the KFC is not prevented (by means of primary prophylaxis) and treated properly and early (be means of physical medicine and rehabilitation), it will become fixed. Areas covered: The aim of this article is to review the potential role of botulinum toxin type A (BTX-A) intramuscular injections for the treatment of KFC in people with hemophilia (PWH). Expert commentary: Although two recent reports have mentioned the benefits of intramuscular injections of BTX-A in PWH with KFC, the data are still scant and too preliminary. The use of intramuscular injections of BTX-A in PWH today should not be recommended until more case studies/small series (ideally well-designed clinical trials) fully demonstrate that this is safe and effective. The risks of intramuscular injections to a hemophilia patient cannot be underestimated (iatrogenic muscle hematomas and pseudotumors). This paper calls the attention of hemophilia treaters on the potential risks of this apparently interesting technique. The current use of BTX-A intramuscular injections in KFC of PWH could make no sense. Raising false expectations in these patients should be avoided.

    Byrne, John M; Loo, Lawrence K; Giang, Dan W

    2015-09-01

    Duty hour limits challenge professional values, sometimes forcing residents to choose between patient care and regulatory compliance. This may affect truthfulness in duty hour reporting. We assessed residents' reasons for falsifying duty hour reports. We surveyed residents in 1 sponsoring institution to explore the reasons for noncompliance, frequency of violations, falsification of reports, and the residents' awareness of the option to extend hours to care for a single patient. The analysis used descriptive statistics. Linear regression was used to explore falsification of duty hour reports by year of training. The response rate was 88% (572 of 650). Primary reasons for duty hour violations were number of patients (19%) and individual patient acuity/complexity (19%). Junior residents were significantly more likely to falsify duty hours (R = -0.966). Of 124 residents who acknowledged falsification, 51 (41%) identified the primary reason as concern that the program will be in jeopardy of violating the Accreditation Council for Graduate Medical Education (ACGME) duty hour limits followed by fear of punishment (34, 27%). This accounted for more than two-thirds of the primary reasons for falsification. Residents' falsification of duty hour data appears to be motivated by concerns about adverse actions from the ACGME, and fear they might be punished. To foster professionalism, we recommend that sponsoring institutions educate residents about professionalism in duty hour reporting. The ACGME should also convey the message that duty hour limits be applied in a no-blame systems-based approach, and allow junior residents to extend duty hours for the care of individual patients.

    2017-01-01

    Working hours across the world are falling, but considerable variation remains. In some countries people work 70% more hours per year, on average, than in other countries. Much of this variation is due to differences in the prevalence of part-time work and patterns of female labor market participation. Looking ahead, the question of how reducing working hours will affect productivity is significant. In addition, how individuals divide up their leisure and work time and what the appropriate wo...

    In this paper we set out the economic grounds for restrictions on long working hours and conduct an empirical analysis using surveys from the perspective of behavioral economics. The results of the analysis indicate that, on a year-on-year basis, if state of health improves, the probability of working more than 60 hours per week increases significantly, but that even when state of health deteriorates there is no decrease in the probability of working long hours. Moreover, among male managemen...

    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. 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. This paper outlines the study protocol including theoretical basis, study hypotheses and outcome measures for this assessor-masked, randomised comparison trial comparing group versus

    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. MÉTODOS: Vinte coelhos foram submetidos à enxertia autóloga intramuscular de gordura em coxa direita após lipoaspiração. Os grupos foram determinados conforme os dias pós-operatórios (DPO em que ocorreu a eutanásia: 60 DPO, 90DPO, 120 DPO. Em seguida, o pulmão e o fígado foram ressecados e encaminhados ao laboratório de histopatologia para análise em busca de lesão tardia secundária a evento de embolia gordurosa prévia nos tecidos. RESULTADOS: Foi evidenciada uma alteração na amostra a analise macroscópica com alteração da coloração do tecido hepático de forma heterogênea. Não houve alterações compatíveis com repercussão de processo embólico à microscopia. CONCLUSÃO: A opção pela realização de uma técnica de lipoenxertia menos traumática e com pequeno tempo cirúrgico pode ser considerada protetora para eventos embólicos, não havendo repercussão embólica a tardiamente.

  6. Haematological and biochemical alterations caused by epidural and intramuscular administration of xylazine hydrochloride in dromedary camels (Camelus dromedarius

    2012-09-01

    Full Text Available 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.

  7. Genetics of Marbling in Wagyu Revealed by the Melting Temperature of Intramuscular and Subcutaneous Lipids

    2017-01-01

    Full Text Available Extreme marbling or intramuscular deposition of lipid is associated with Wagyu breeds and is therefore assumed to be largely inherited. However, even within 100% full blood Wagyu prepared under standard conditions, there is unpredictable scatter of the degree of marbling. Here, we evaluate melting temperature (Tm of intramuscular fat as an alternative to visual scores of marbling. We show that “long fed” Wagyu generally has Tm below body temperature but with a considerable range under standardized conditions. Individual sires have a major impact indicating that the variation is genetic rather than environmental or random error. In order to measure differences of lower marbling breeds and at shorter feeding periods, we have compared Tm in subcutaneous fat samples from over the striploin. Supplementary feeding for 100 to 150 days leads to a rapid decrease in Tm of 50% Red Wagyu (Akaushi : 50% European crosses, when compared to 100% European. This improvement indicates that the genetic effect of Wagyu is useful, predictable, and highly penetrant. Contemporaneous DNA extraction does not affect the measurement of Tm. Thus, provenance can be traced and substitution can be eliminated in a simple and cost-effective manner.

    2017-11-01

    We report on a patient with postsurgical cystoid macular edema (CME) after phacoemulsification and multifocal intraocular lens (MIOL) implantation. At first, there was a very good reaction to intravitreal triamcinolone, inducing complete regression of the edema without increasing intraocular pressure (IOP). One year later the patient suffered from retinal detachment and was treated with vitrectomy, laser, and gas tamponade. Afterward, he developed macular pucker with edema. After surgical treatment with pucker peeling and intravitreal triamcinolone, the patient showed a steroid response and an increase IOP. Postoperatively, there was a recurrence of CME. A coincidental administration of a steroid injection intramuscularly by the general practitioner achieved a prompt reduction of the CME without increasing IOP. This case shows that an initially good reaction to triamcinolone without increasing IOP does not rule out a future steroid response, and that a potential treatment option for CME in patients with a known steroid response could consist of intramuscularly injected steroids.

    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. © 2014 John Wiley & Sons Ltd.

    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. © The Author (2015). Published by Oxford University Press on behalf of the Guarantors of Brain. All rights reserved.

    The aim of this study was to prepare riboflavin laurate (RFL) nanosuspensions as an intramuscular injection for long-term riboflavin supplementation. Stable RFL nanosuspensions were obtained by injecting RFL/poloxamer solution in N,N-dimethyl formamide into a trehalose solution. Long soft nanostructures initially appeared and then tube-like rigid nanostructures were obtained after removal of solvents according to the transmission electron microscopic images. The nanosuspensions had narrow size distribution and the mean size was about 300 nm. Molecular self-assembly of RFL may drive the formation of nanostructures. RFL formed a monolayer at the air/water interface and poloxamer 188 could insert into the monolayer. The nanosuspensions were intramuscularly injected into rats to provide long-term riboflavin supplementation for more than 30 days in light of body weight, food intake, and urinary riboflavin. The nanosuspensions were also used to resist the riboflavin deficiency induced by methotrexate chemotherapy. RFL nanosuspensions are a promising nanomedicine for long-term riboflavin supplementation.

    2017-01-01

    Ectopic adiposity has gained considerable attention because of its tight association with metabolic and cardiovascular health in persons with spinal cord injury (SCI). Ectopic adiposity is characterized by the storage of adipose tissue in non-subcutaneous sites. Magnetic resonance imaging (MRI) has proven to be an effective tool in quantifying ectopic adiposity and provides the opportunity to measure different adipose depots including intermuscular adipose tissue (IMAT) and intramuscular adipose tissue (IntraMAT) or in-tramuscular fat (IMF). It is highly important to distinguish and clearly define these compartments, because controversy still exists on how to accurately quantify these adipose depots. Investigators have relied on separating muscle from fat pixels based on their characteristic signal intensities. A common technique is plotting a threshold histogram that clearly separates between muscle and fat peaks. The cut-offs to separate between muscle and fat peaks are still not clearly defined and different cut-offs have been identified. This review will outline and compare the Midpoint and Otsu techniques, two methods used to determine the threshold between muscle and fat pixels on T1 weighted MRI. The process of water/fat segmentation using the Dixon method will also be outlined. We are hopeful that this review will trigger more research towards accurately quantifying ectopic adiposity due to its high relevance to cardiometabolic health after SCI.

    The parameters involved in the induction of resistance against Schistosoma mansoni by injection of irradiated, artificially transformed schistosomula were studied in mice. Single intramuscular injections of 500 schistosomula exposed to radiation doses in the range 2.3 to 160 krad. resulted in significant protection ( in the range 20 to 50% as assessed by reduced worm burdens) against a challenge infection administered at intervals from 3 to 24 weeks post-vaccination. However, schistosomular irradiated with 20 krad. consistently resulted in better protection than those exposed to either higher or lower radiation doses despite the persistence of stunted adults from the infections irradiated with 2.3 krad. Vaccination with 40 krad. schistosomula resulted in significant protection in terms of reduced worm and tissue egg burdens and increased survival following lethal challenge. Varying the number of irradiated schistosomula, the frequency and route of their administration, the site of challenge and the strain of host all failed to enhance the level of resistance. However, percutaneously applied, irradiated cercariae were found to be more effective in stimulating resistance (60%) than intramuscularly injected, irradiated schistosomula (40%). (author)

    Slight differences in formulation may change the plasma kinetics and ecto-endoparasiticide activity of endectocide compounds. This work reports on the disposition kinetics and plasma availability of ivermectin (IVM) after subcutaneous (SC) and intramuscular (IM) administration as an oil-based formulation to cattle. Parasite-free Aberdeen Angus calves (n = 24; 240-280 kg) were divided into three groups (n = 8) and treated (200 microg/kg) with either an IVM oil-based pharmaceutical preparation (IVM-TEST formulation) (Bayer Argentina S.A.) given by subcutaneous (Group A) and intramuscular (Group B) injections or the IVM-CONTROL (non-aqueous formulation) (Ivomec, MSD Agvet) subcutaneously administered (Group C). Blood samples were taken over 35 days post-treatment and the recovered plasma was extracted and analyzed by HPLC using fluorescence detection. IVM was detected in plasma between 12 h and 35 days post-administration of IVM-TEST (SC and IM injections) and IVM-CONTROL formulations. Prolonged IVM absorption half-life (p oil-based formulation examined in this trial, compared to the standard preparation, may positively impact on its strategic use in cattle.

    To evaluate the magnetic resonance (MR) features of intramuscular myxoma (IM) compared with its pathological findings. Two radiologists retrospectively reviewed records and imaging studies of patients with histologically proven IM. Two radiologists also analyzed by consensus all the MR studies (pre- and post-contrast T1-weighted and T2-weighted sequences) and a pathologist reviewed the available histological material. Seventeen patients with 18 histologically proven IM were reviewed. Histological samples of 11 of these 18 tumors were available for pathological analysis. There were 14 women and three men, with a mean age of 58.9 years. IM involved predominantly the thigh (n=10). MR imaging showed well-circumscribed intramuscular masses, hypointense on T1-weighted and hyperintense on T2-weighted images. Eleven masses were homogeneous and seven slightly heterogeneous due to fibrous septa. Enhanced MR imaging demonstrated three different patterns: peripheral enhancement (n=1), peripheral and patchy internal enhancement (n=7) or peripheral and linear internal enhancement (n=4). Intratumoral cysts were detected in four masses. MR imaging showed the presence of a pseudocapsule (n=12), fat around the lesion (n=16) and peritumoral edema (n=16). Histologically, all the tumors were hypocellular, hypovascular and myxoid. Peripheral areas of collagenous fibers formed a partial capsule and IM often merged into surrounding muscular fibers. More cellular tumors and those with scanty myxoid stroma tended to show a more prominent internal enhancement. IM shows several recognizable MR features which suggest its diagnosis. (orig.)

    Full Text Available Ostruthin, a natural bioactive compound mainly occurring in the roots of Peucedanum ostruthium, is the focus of this study. P. ostruthium was collected from twelve locations in the Swiss alpine region and reared in an experimental field, subdivided into twelve lots over two years. In the spring and fall, a portion of each of the twelve accessions was harvested and separated into above and below ground plant parts. The dried plants were then extracted with 60 % ethanol using accelerated solvent extraction (ASE and analyzed using high pressure liquid chromatography (HPLC.The above and below ground plant parts were then analyzed concerning their dry matter yield (DMY, their ostruthin concentration and their ostruthin yield. Focusing on ostruthin, it was found that the below ground plant parts harvested in the fall rendered the highest ostruthin yield. Furthermore, a variability concerning ostruthin among the twelve accessions was found. This variability among the accessions is of interest with regards to a breeding program used to develop a cultivar with a high ostruthin yield.

    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

    2012-10-01

    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

    2014-10-01

    To examine the degree to which states' work hour regulations for nurses-policies regarding mandatory overtime and consecutive work hours-decrease mandatory overtime practice and hours of work among registered nurses. We analyzed a nationally representative sample of registered nurses from the National Sample Survey of Registered Nurses for years 2004 and 2008. We obtained difference-in-differences estimates of the effect of the nurse work hour policies on the likelihood of working mandatory overtime, working more than 40 hours per week, and working more than 60 hours per week for all staff nurses working in hospitals and nursing homes. The mandatory overtime and consecutive work hour regulations were significantly associated with 3.9 percentage-point decreases in the likelihood of working overtime mandatorily and 11.5 percentage-point decreases in the likelihood of working more than 40 hours per week, respectively. State mandatory overtime and consecutive work hour policies are effective in reducing nurse work hours. The consecutive work hour policy appears to be a better regulatory tool for reducing long work hours for nurses. © Health Research and Educational Trust.

    Intramuscular degeneration process of Duchenne dystrophy skeletal muscles was investigated by longitudinal skeletal muscle imaging with high-field-strength NMR-CT of 1.5 Tesla. Thigh muscles in 10 cases ranging in age from 4 to 19 years were examined by T{sub 1}-weighted longitudinal images (TR=215{approx}505 ms, TE=19{approx}20 ms). The following results were obtained. Skeletal muscle degeneration was depicted as high signal intensity area reflecting its high fat contents. These high signal intensity areas had a longitudinally streaky appearance in parallel direction with myofibers. These findings were more prominent toward myotendon junction than muscle bellies. Skeletal muscle degeneration progressed rapidly between 7 to 10 years of age, and reached a plateau after that. (author).

    As part of an enrofloxacin pharmacokinetic study, concentrations of enrofloxacin and ciprofloxacin (metabolite) were measured in various tissues (brain, heart, kidney, liver, lung, and spleen) collected from treated (subcutaneous delivery, n = 3; intramuscular delivery, n = 3; untreated controls, n = 2) adult female Xenopus laevis by using HPLC. Enrofloxacin was rapidly absorbed after administration by either route and readily diffused into all sampled tissues. Enrofloxacin and ciprofloxacin were present in the tissue samples collected at 8 h. The highest average tissue concentrations for enrofloxacin were found in kidney, with the lowest concentrations in liver. Ciprofloxacin tissue concentrations paralleled but were always lower than those of enrofloxacin for all time points and tissues except brain and kidney. These results, together with previously published pharmacokinetic data and known minimal inhibitory concentrations of common pathogenic bacteria, provide a strong evidence-based rationale for choosing enrofloxacin to treat infectious diseases in X. laevis.

    Full Text Available Ketamine, among wide variety of sedative drugs, has shown beneficial effects when using during the procedural sedation, specifically in pediatrics. Various parameters should be considered in order to perform a safe and effective procedural sedation including optimum dosage of the sedative, administration methods of sedation, and need for applying any adjuvant drug. In this study, we aimed to review the studies, which have compared the efficacy of the different ways of the injection of ketamine such as intravenous or intramuscular ketamine application. Based on data obtained from the related articles, efficacy and safety of these two methods of ketamine usage in the pediatric procedural sedation were widely similar, but the intravenously administration of the ketamine can be proposed as the preferable mode.

    Crossbred pigs weighing 80-110 kg were injected intramuscularly in the ham with 8.8 mg/kg tylosin. Animals were slaughtered in groups of 3 at intervals of 4 h, and 1, 2, 4, and 8 days after injection, and samples of blood, injected muscle, uninjected muscle, liver, and kidney were analyzed by liquid chromatography (LC) and by bioassay using Sarcina lutea as the test organism. The LC method was far more sensitive with a detection limit of less than 0.1 ppm, while the detection limit by bioassay was about 0.5 ppm in tissue. Results by bioassay and LC sometimes differed considerably for tissue samples. Residues in all tissues were below the tolerance limit of 0.2 ppm at 24 h, except in the injected muscle in one animal. Residues were not detected in any tissue of any animal at 48 h after treatment.

    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 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.

    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.

    The aim of this study was to investigate whether intramuscular administration of the 5-HT(3) receptor antagonist granisetron reduces experimental muscle pain induced by repeated intramuscular injections of acidic saline into the masseter muscles. Twenty-eight healthy and pain-free volunteers, fourteen women and fourteen men participated in this randomized, double-blind and placebo-controlled study. After a screening examination and registration of the baseline pressure-pain threshold (PPT), the first simultaneous bilateral injections of 0·5 mL acidic saline (9 mg mL(-1) , pH 3·3) into the masseter muscles were performed. Two days later, PPT and pain (VAS) were re-assessed. The masseter muscle was then pre-treated with 0·5 mL granisetron (Kytril(®) 1 mg mL(-1) pH 5·3) on one side and control substance (isotonic saline, 9 mg mL(-1) pH 6) on the contralateral side. Two minutes thereafter a bilateral simultaneous injection of 0·5 mL acidic saline followed. The evoked pain intensity, pain duration, pain area and PPT were assessed. The volunteers returned 1 week later to re-assess VAS and PPT. On the side pre-treated with granisetron, the induced pain had significantly lower intensity and shorter duration (P granisetron on pain duration was significant only in women (P granisetron has a pain-reducing effect on experimentally induced muscle pain by repeated acidic saline injection. © 2013 John Wiley & Sons Ltd.

    Full text: Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) which is available as over-the-counter (OTC) medication for the systemic and topical treatment of painful and inflammatory conditions such as arthritis and back pain. This study was undertaken to investigate the distribution and retention of intramuscularly injected diclofenac sodium (DFN) in white New Zealand rabbit using gamma scintigraphy. A new formulation of the nonselective NSAID diclofenac sodium suitable for intramuscular injection has been developed using sesame oil as a vehicle. The hypothesis of present work is to maintain effective concentration of DFN in blood for prolonged time period. A novel method of radiolabeling with 99m Tc-pertechnetate was adopted using stannous ions as reducing agent. The radiolabeled product was tested for quality control using ascending instant thin layer chromatography (ITLC) technique. ITLC-SG, (Gelman, USA) and acetone were used as the stationary phase and mobile phase respectively in the chromatographic procedure. In vitro and in vivo stability parameters were evaluated. Biodistribution studies and blood kinetics of 99m Tc-DFN was done in balb c mice and white New Zealand rabbit respectively. 99m Tc-DFN retention at depot site was evaluated using gamma scintigraphy. 99m Tc-DFN, when incubated at 37 deg C for 24 hr in normal saline and human serum showed disintegration of only 6.6% and 3.5% respectively, thereby indicating high stability of radiolabeled product. Protein binding studies of 99m Tc-DFN shows more than 85% serum protein binding. Blood clearance of radiopharmaceutical in rabbits, exhibited a biphasic exponential pattern in i.v. bolus while in i.m. linear control release pattern were observed up to 24 hrs

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

    Severe malaria remains a major cause of mortality and morbidity for children living in many tropical regions. With the emergence of strains of Plasmodium falciparum resistant to both chloroquine and quinine, alternative antimalarial agents are required. The artemisinin group of compounds are rapidly effective in severe disease when given by intramuscular or intravenous injection. However, these routes of administration are not always available in rural areas. In an open, randomized comparison 109 Vietnamese children, aged between 3 months and 14 years, with severe P.falciparum malaria, were allocated at random to receive artemisinin suppositories followed by mefloquine (n = 37), intramuscular artesunate followed by mefloquine (n = 37), or intravenous quinine followed by pyrimethamine/sulfadoxine (n = 35). There were 9 deaths: 2 artemisinin, 4 artesunate and 5 quinine-treated children. There was no difference in fever clearance time, coma recovery, or length of hospital stay among the 3 groups. However, parasite clearance times were significantly faster in artemisinin and artesunate-treated patients than in those who received quinine (P children receiving these drugs had lower peripheral reticulocyte counts by day 5 of treatment than those in the quinine group (P = 0.011). No other adverse effect or toxicity was found. There was no treatment failure in these 2 groups, but 4 patients in the quinine group failed to clear their parasites within 7 d of starting treatment and required alternative antimalarial therapy. Artemisinin suppositories are easy to administer, cheap, and very effective for treating children with severe malaria. In rural areas where medical facilities are lacking these drugs will allow antimalarial therapy to be instituted earlier in the course of the disease and may therefore save lives.

    The present study compares the safety and efficacy of a needle-free, intradermal Mycoplasma hyopneumoniae vaccine to an intramuscular one. 420 piglets (21+3 days of age) were randomly assigned to two vaccination groups (intradermal vaccination V1 (n=138), intramuscular vaccination V2 (n=144)) and one unvaccinated control group (CG, n=138). As safety parameters clinical observations, local injection site reactions (ISR) and rectal temperatures were assessed. Average daily weight gain (ADWG) and pneumonic lung lesions (LL) were measured as efficacy parameters. ISRs were minor in V1. After both vaccinations, no adverse impact on appetite was observed and mean rectal temperatures remained within physiological range. ADWG during the fattening period was significantly higher in vaccinated groups (V1: 913.4 g, V2: 924.5 g) compared with CG (875.6 g). No differences in ADWG were observed between V1 and V2. Vaccinated pigs had a significantly reduced mean extent of LL compared with CG. V1 was superior in reducing the extent and prevalence of LL compared with V2. These results reveal that a needle-free intradermal vaccination is safe and efficacious in reducing both the prevalence and extent of lung lesions, as well as in improving performance parameters, in a farrow-to-finish farm with a late onset of M hyopneumonia e infection. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

    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.)

    Intramuscular fat (IMF) has been demonstrated as one of the crucial factors of livestock meat quality. The MAT2B protein with MAT2α catalyzes the formation of methyl donor S- adenosylmethionine (SAMe) to mediate cell metabolism including proliferation and apoptosis. However, the regulatory effect of MAT2B on IMF deposition is still unclear. In this study, the effect of MAT2B on adipogenesis and its potential mechanism during porcine intramuscular preadipocyte differentiation was studied. The results showed that overexpression of MAT2B promoted adipogenesis and significantly up-regulated the mRNA and protein levels of adipogenic marker genes including FASN, PPARγ and aP2, consistently, knockdown of MAT2B inhibited lipid accumulation and down-regulated the mRNA and protein levels of the above genes. Furthermore, flow cytometry and EdU-labeling assay indicated that MAT2B regulate adipogenesis was partly due to influence intracellular SAMe levels and further affect cell clonal expansion. Also, increased expression of MAT2B activated the phosphorylations of AKT and ERK1/2, whereas knockdown of MAT2B blocked AKT signaling and repressed the phosphorylation of ERK1/2. Moreover, the inhibitory effect of LY294002 (a specific PI3K inhibitor) on the activities of AKT and ERK1/2 was partially recovered by overexpression of MAT2B in porcine intramuscular adipocytes. Finally, Co-IP experiments showed that MAT2B can directly interact with AKT. Taken together, our findings suggested that MAT2B acted as a positive regulator through modifying SAMe levels as well as activating AKT/ERK signaling pathway to promote porcine intramuscular adipocyte differentiation. - Highlights: • MAT2B up-regulates the expression of adipogenic marker genes and promotes porcine intramuscular preadipocyte differentiation. • MAT2B influences intracellular SAMe levels and further affects cell clonal expansion. • MAT2B interacts with AKT and activates AKT/ERK signaling pathway.

    Ureaplasma spp are the most commonly isolated microorganisms in association with preterm birth. Maternal erythromycin administration is a standard treatment for preterm prelabor rupture of membranes. There is little evidence of its effectiveness in eradicating Ureaplasma spp from the intrauterine cavity and fetus. We used a sheep model of intrauterine Ureaplasma spp infection to investigate the efficacy of repeated maternal intramuscular and intraamniotic erythromycin treatment to eradicate such an infection. Thirty ewes with singleton pregnancies received an intraamniotic injection of 10(7) color change units of erythromycin-sensitive Ureaplasma parvum serovar 3 at 55 days' gestation. At 116 days' gestation, 28 ewes with viable fetuses were randomized to receive (1) intraamniotic and maternal intramuscular saline solution treatment (n = 8), (2) single intraamniotic and repeated maternal intramuscular erythromycin treatment (n = 10), or (3) single maternal intramuscular and repeated intraamniotic erythromycin treatment (n = 10). Fetuses were surgically delivered at 125 days' gestation. Treatment efficacy was assessed by culture, quantitative polymerase chain reaction, and histopathologic evaluation. Animals treated with intraamniotic erythromycin had significantly less viable U parvum serovar 3 in the amniotic fluid at delivery. However, neither combination of maternal intramuscular and intraamniotic erythromycin treatment successfully cleared U parvum serovar 3 from the amniotic fluid or fetal tissues. Three de novo erythromycin-resistant U parvum isolates were identified in erythromycin-treated animals. Erythromycin treatment, given both to the ewe and into the amniotic cavity, fails to eradicate intrauterine and fetal U parvum serovar 3 infection and may lead to development of erythromycin resistant U parvum.

    First, we review a result in our previous paper, of how a ten-dimensional superparticle, taken off-shell, has a hidden eleven-dimensional superPoincare symmetry. Then, we show that the physical sector is defined by three first-class constraints which preserve the full eleven-dimensional symmetry. Applying the same concepts to the eleven dimensional superparticle, taken off-shell, we discover a hidden twelve dimensional superPoincare symmetry that governs the theory.

    Trypanosoma cruzi, the etiological agent of Chagas disease, is transmitted by triatomines that have been described in a large number of studies. Most of those studies are related to external morphology and taxonomy, but some biochemical, genetic and physiological studies have also been published. There are a few publications in the literature about the internal organs of Triatominae, for instance the spermathecae, which are responsible for storing and maintaining the viability of the spermatozoids until the fertilization of the oocytes. This work aims to study the spermathecae of twelve species of triatomines obtained from the Triatominae Insectarium of the Faculty of Pharmaceutical Sciences, UNESP, Araraquara, using optical microscopy and scanning electron microscopy. The spermathecae of the twelve species studied showed three morphological patterns: a) P. herreri sn, P. lignarius, P. megistus, Triatoma brasiliensis, T. juazeirensis, T. sherlocki and T. tibiamaculata have spermathecae with a thin initial portion and an oval-shaped final portion; b) R. montenegrensis, R. nasutus, R. neglectus, R. pictipes and R. prolixus have tubular and winding spermathecae; c) T. infestans has oval spermathecae. In addition to the three morphological patterns, it was noted that each of the twelve species has particular features that differentiate them. Copyright © 2017 Elsevier B.V. All rights reserved.

    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 (Asian (Pakistani/Indian/Bangladeshi) versus Other) and induced versus spontaneous labour. The effectiveness of pain 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

    2013-01-01

    In July 2011, the ACGME implemented new rules that limit interns to 16 hours of work in a row, but continue to allow 2nd-year and higher resident physicians to work for up to 28 consecutive hours. Whether the ACGME's 2011 work hour limits went too far or did not go far enough has been hotly debated. In this article, we do not seek to re-open the debate about whether these standards get matters exactly right. Instead, we wish to address the issue of effective enforcement. That is, now that new work hour limits have been established, and given that the ACGME has been unable to enforce work hour limits effectively on its own, what is the best way to make sure the new limits are followed in order to reduce harm to residents, patients, and others due to sleep-deprived residents? We focus on three possible national approaches to the problem, one rooted in funding, one rooted in disclosure, and one rooted in tort law. © 2013 American Society of Law, Medicine & Ethics, Inc.

  17. How extreme is extreme hourly precipitation?

    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.

    In this study, the cross-sectional association of paid work hours with episodes of work absence was examined in a cohort of police officers. Study subjects were participants from the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study examined between 2004 and 2009. Among 395 study participants with complete data, day-by-day work history records during the one-year period prior to date of examination were used to determine episodes of one-day and three day work absence. The Negative binomial regression analysis was used to examine rate ratios (RR) of work absence. Analyses were also stratified by gender. A one-hour increase in total work hours was associated with 5% reduction in rate of one-day work absence (RR = 0.95, 95% CI: 0.92 - 0.98) and with 8% reduction in rate of three-day work absence (RR = 0.92, 95% CI: 0.89 - 0.95). The association of total work hours with episodes of one-day work absence was significant only in men while the association with episodes of three-day work absence was evident in men and women. In conclusion, in this cohort of police officers, work hours were negatively associated with both durations of work absence (one-day, > or = 3 consecutive days).

    Full Text Available Background. Acute carbon monoxide poisoning (ACOP is a significant cause of morbidity and mortality in many countries. Twelve Hand Jing Points (THJP have been believed to be effective to treat all kinds of emergency calls in traditional Chinese medicine (TCM for more than 3000 years. This randomized controlled trial (RCT is designed to evaluate the effectiveness of THJP in curing acute carbon monoxide poisoning in first aid treatment. This paper reports the protocol of the trial. Methods/Design. This RCT is a multicenter, randomized, controlled study undergoing in China. The compliant patients are divided into the bloodletting group and standard of care group. With first aid treatments given to both of the groups, the bloodletting group is bleeding at THJP upon being hospitalized. Primary outcomes and secondary outcomes will be measured and compared between these two groups. Before treatment, immediately after treatment, and 30 minutes, 1 hour, and 4 hours after treatment, patients’ basic vital signs and state of consciousness were observed. Before treatment and 1 and 4 hours after treatment, carboxyhemoglobin concentration in venous blood samples was detected. Discussion. The objective of this study is to provide convincing evidence to clarify the efficacy and safety of THJP for early treatment of acute carbon monoxide poisoning.

    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 hourly average wind speed data recorded by CNMCA (Centro Nazionale di Meteorologia e Climatologia Aeronautica) have been used to study the statistical properties of the wind speed at nine locations on Sicily. By grouping the observations month by month, we show that the hourly average wind speed, with calms omitted, is represented by a Weibull function. The suitability of the distribution is judged by the discrepancies between the observed and calculated values of the monthly average wind speed and of the standard deviation. (Author)

  5. Ethical aspects of limiting residents' work hours.

    Science.gov (United States)

    Wiesing, Urban

    2007-09-01

    The regulation of residents' work hours involves several ethical conflicts which need to be systematically analysed and evaluated. ARGUMENTS AND CONCLUSION: The most important ethical principle when regulating work hours is to avoid the harm resulting from the over-work of physicians and from an excessive division of labour. Additionally, other ethical principles have to be taken into account, in particular the principles of nonmaleficence and beneficence for future patients and for physicians. The article presents arguments for balancing the relevant ethical principles and analyses the structural difficulties that occur unavoidably in any regulation of the complex activities of physicians.

    Intramuscularly administered, anti-tumour drugs induce severe side effects due to their direct contact with body tissues and initial burst effect. In this study, to solve this problem, a novel double-reversible thermogel system (DRTG) for the intramuscular administration of irinotecan was developed. This irinotecan-loaded DRTG was prepared by dispersing the irinotecan-loaded thermoreversible solid lipid nanoparticles (SLNs) in the thermoreversible hydrogel. In DRTG, the former was solid at 25°C but converted to liquid at 36.5°C; in contrast, the latter existed in a liquid form but transformed to gel state in the body. The DRTG was easily administered intramuscularly. Its particle size and drug content were not noticeably changeable, resulting that it was stable at 40°C for at least 6months. Compared to the irinotecan-loaded solution and conventional hydrogel, the DRTG significantly delayed drug release, leading to a reduced burst effect. Moreover, it showed decreased C max and maintained the sustained plasma concentrations at a relatively low level for the long period of 60h in rats, resulting in ameliorated side effects of the anti-tumour drug. Furthermore, it gave significantly improved anti-tumour efficacy in tumour-bearing mice compared to the hydrogel but, unlike the conventional hydrogel, induced no body weight loss and local damage to the muscle. Thus, this DRTG with improved antitumor efficacy without initial burst effect and toxicity could provide a potential pharmaceutical system for the intramuscular administration of irinotecan. Intramuscularly administered, anti-tumour drugs induce severe side effects due to their direct contact with body tissues and initial burst effect. To solve this problem, we developed a novel double-reversible thermogel system (DRTG) for the intramuscular administration of irinotecan. Unlike the conventional hydrogel, the DRTG is a dispersion of the irinotecan-loaded thermoreversible solid lipid nanoparticles in the

    Electrochemotherapy provides good local tumor control but requires adjuvant treatment for increased local response and action on distant metastasis. In relation to this, intramuscular interleukin-12 (IL-12) gene electro-transfer, which provides systemic shedding of IL-12, was combined with local electrochemotherapy with cisplatin. Furthermore, the dependence on tumor immunogenicity and immunocompetence of the host on combined treatment response was evaluated. Sensitivity of SA-1 sarcoma and TS/A carcinoma cells to electrochemotherapy with cisplatin was tested in vitro. In vivo, intratumoral electrochemotherapy with cisplatin (day 1) was combined with a single (day 0) or multiple (days 0, 2, 4) intramuscular murine IL-12 (mIL-12) gene electrotransfer. The antitumor effectiveness of combined treatment was evaluated on immunogenic murine SA-1 sarcoma in A/J mice and moderately immunogenic murine TS/A carcinoma, in immunocompetent BALB/c and immunodeficient SCID mice. Electrochemotherapy in vitro resulted in a similar IC 50 values for both sarcoma and carcinoma cell lines. However, in vivo electrochemotherapy was more effective in the treatment of sarcoma, the more immunogenic of the tumors, resulting in a higher log cell kill, longer specific tumor growth delay, and also 17% tumor cures compared to carcinoma where no tumor cures were observed. Adjuvant intramuscular mIL-12 gene electrotransfer increased the log cell kill in both tumor models, potentiating the specific tumor growth delay by a factor of 1.8-2 and increasing tumor cure rate by approximately 20%. In sarcoma tumors, the potentiation of the response by intramuscular mIL-12 gene electrotransfer was dose-dependent and also resulted in a faster onset of tumor cures. Comparison of the carcinoma response to the combined treatment modality in immunocompetent and immunodeficient mice demonstrated that the immune system is needed both for increased cell kill and for attaining tumor cures. Based on the comparison of

    This study aimed to investigate both the mean daily physical activity and the hour-by-hour physical activity patterns across the day using accelerometry and how they are associated with neighborhood walkability and individual income. Moderate physical activity (MPA) was assessed by accelerometry in 2252 adults in the city of Stockholm, Sweden. Neighborhood walkability (residential density, street connectivity, and land use mix) was objectively assessed within 1000m network buffers around the participants' residence and individual income was self-reported. Living in a high walkability neighborhood was associated with more mean daily MPA compared with living in a low walkability neighborhood on weekdays and weekend days. Hour-by-hour analyses showed that this association appeared mainly in the afternoon/early evening during weekdays, whereas it appeared across the middle of the day during weekend days. Individual income was associated with mean daily MPA on weekend days. On weekdays, the hour-by-hour analyses showed that high income was associated with more MPA around noon and in late afternoon/early evening, whereas low income was associated with more MPA at the hours before noon and in the early afternoon. During the weekend, high income was more consistently associated with higher MPA. Hour-by-hour accelerometry physical activity patterns provides a more comprehensive picture of the associations between neighborhood walkability and individual income and physical activity and the variability of these associations across the day.

    Ejiri, A.

    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.

    Full Text Available Abstract Background 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. Methods 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. Results 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

    2007-01-01

    To compare the efficacy and tolerability of oral itraconazole against intramuscular meglumine antimoniate in the treatment of Cutaneous Leishmaniasis (CL). Two hundred eligible and consenting patients of Cutaneous Leishmaniasis (CL) were divided in two groups with 100 patients in each. The number and location of the lesions were documented and clinical types of cutaneous leishmaniasis were noted. The diagnosis was confirmed by skin slit smear and histopathology of the lesional skin. Culture on Nicolle Novy MacNeal (NNN) medium and Leishmanin test was done in all patients. All the patients in both groups were subjected to complete blood picture, urine examination, serum urea and creatinine levels and ECG examination. One group was given itraconazole 100 mg twice daily orally for a duration of 6-8 weeks. The other group was given meglumine antimoniate 10 cc in the form of deep intramuscular injections for 15-30 days. The efficacy of the treatment was judged by clinical and parasitological response. Side effects of the agents were also noted during treatment. Out of 200 patients studied, 185 were males and 15 were females. The mean age of presentation was 30 + 6.6 years. Single lesion was seen in 132 (66%) subjects whereas 68 (34%) subjects had multiple lesions. Slit skin smears were positive in 50 (25%) of the patients. Skin biopsy yielded the presence of LT bodies in 150 (75%) subjects. The culture was positive in 102 (51%) cases. Leishmanin test was positive in 94% subjects. Seventy-five (75%) patients on itraconazole therapy showed complete clinical and parasitological cure in 4-8 weeks duration. A rise in ALT was seen in 12% subjects. Five (5%) subjects did not show any improvement till the end of therapy. Sixty-five (65%) subjects on meglumine antimoniate showed complete healing in 15-30 days. In 35 (35%) of the patients, the treatment had to be stopped due to intolerable side-effects. Four cases of lupoid leishmaniasis and 4 cases of sporotrichoid leishmaniasis

    Objectives Cardiorespiratory parameters and anaesthesia quality in cats anaesthetised with either intramuscular (IM) alfaxalone or ketamine both combined with dexmedetomidine and butorphanol for castration were evaluated. Methods Thirty-two client-owned cats were randomly assigned to receive either alfaxalone (A; 3 mg/kg IM) or ketamine (K; 5 mg/kg IM), combined with dexmedetomidine (10 μg/kg) and butorphanol (0.2 mg/kg). Heart rate (HR), respiratory rate (RR) and rectal temperature (T°) were recorded prior to drug administration. Pulse rate (PR) and RR were recorded 10 (T 10 ) and 15 (T 15 ) mins after injection (T 0 ). Cardiorespiratory values (PR, RR, SPO 2 , blood pressure, P E 'CO 2 ) were recorded every 5 mins for the duration of the procedure. Pain at injection, intubation and recovery were evaluated with simple descriptive scores. Feasibility of anaesthesia was evaluated by the number of top-ups of anaesthetic needed. Cat attitude, ability to walk and presence of ataxia were assessed several times after extubation (T exmin ) and the time between injection and extubation recorded. Pain was assessed at T ex120 and T ex240 with the 4Avet-pain score. Results The RR was significantly lower in group K at T 10 (RR K = 28 ±13.35 breaths per minute [brpm], RR A = 43.24 ±7.04 brpm) and T 15 (RR K = 28 ±11.53 brpm vs RR A = 43 ±12.18 brpm). Time to extubation was significantly longer in group A (T A = 62 ±14.6 mins, T K = 45.13 ± 7.38 mins). Cats in group K needed more top-ups, were more ataxic at T ex120 , had a worse recovery score at T ex60 and were less willing to walk at T ex30 . Conclusions and relevance Cats receiving alfaxalone had a longer but better quality recovery. Cardiorespiratory parameters were stable and within clinically acceptable values following IM injection of either alfaxalone or ketamine in healthy cats. Intramuscular alfaxalone is a suitable alternative to ketamine for short procedures requiring anaesthesia when used in combination

    To investigate the role of the muscular renin-angiotensin system (RAS) in human muscular dystrophy, we used immunohistochemistry and Western blotting to examine the cellular localization of angiotensin-converting enzyme (ACE), the angiotensin II type 1 receptor (AT1) and the angiotensin II type 2 receptor (AT2) in muscle biopsies from patients with Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), and congenital muscular dystrophy (CMD). In normal muscle, ACE was expressed in vascular endothelial cells and neuromuscular junctions (NMJs), whereas AT1 was immunolocalized to the smooth muscle cells of blood vessels and intramuscular nerve twigs. AT2 was immunolocalized in the smooth muscle cells of blood vessels. These findings suggest that the RAS has a functional role in peripheral nerves and NMJs. ACE and AT1, but AT2 immunoreactivity were increased markedly in dystrophic muscle as compared to controls. ACE and the AT1 were strongly expressed in the cytoplasm and nuclei of regenerating muscle fibers, fibroblasts, and in macrophages infiltrating necrotic fibers. Double immunolabeling revealed that activated fibroblasts in the endomysium and perimysium of DMD and CMD muscle were positive for ACE and AT1. Triple immunolabeling demonstrated that transforming growth factor-beta1 (TGF-beta1) and ACE were colocalized on the cytoplasm of activated fibroblasts in dystrophic muscle. Furthermore, Western blotting showed increases in the expression of AT1 and TGF-beta1 protein in dystrophic muscle, which coincided with our immunohistochemical results. The overexpression of ACE and AT1 in dystrophic muscle would likely result in the increased production of Ang II, which may act on these cells in an autocrine manner via AT1. The activation of AT1 may induce fibrous tissue formation through overexpression of TGF-beta1, which potently activates fibrogenesis and suppresses regeneration. In conclusion, our results imply that the intramuscular RAS-TGF-beta1 pathway

    Full Text Available The pharmacokinetic profile of cefoperazone was studied in goats following intravenous and intramuscular administration of 20 mg/kg body weight. Cefoperazone concentrations in serum were determined by microbiological assay technique using Escherichia coli (ATCC 10536 as test organism. Following i.v. administration, the cefoperazone serum concentration–time curve was best fitted in a two compartment open model. Cefoperazone has moderate distribution in the body of goats with Vdss of 0.44 ± 0.03 L/kg. The elimination half-life (T0.5(β, area under curve (AUC and total body clearance (Cltot were 1.97 ± 0.14 h, 149.63 ± 8.61 μg ml−1 h−1, and 2.17 ml/min/kg, respectively. Following i.m. administration, the drug was very rapidly absorbed, with an absorption half-life (T0.5(ab of 0.12 ± 0.01 h. The maximum serum concentration (Cmax of 30.42 ± 3.53 μg ml−1 was attained at (Tmax 0.58 ± 0.02 h, with an elimination half-life (T0.5(el of 2.53 ± 0.11 h. The systemic bioavailability of cefoperazone in the goats after i.m. administration was 83.62% and in vitro protein binding was 20.34%. The serum concentrations of cefoperazone along 12 h post i.m. injection in this study were exceeding the MIC of different susceptible micro-organisms responsible for serious disease problems. Consequently, a suitable intramuscular dosage regimen for cefoperazone was 20 mg/kg repeated at 12 h intervals in goats. The drug was detected in urine up to 12 and 18 h following i.v. and i.m. administration, respectively.

    It is widely believed that persons employed in jobs demanding long working hours are at greater risk of physical inactivity than other workers, primarily because they have less leisure time available to undertake physical activity. The aim of this study was to test this hypothesis using prospective data obtained from a nationally representative sample of employed persons. Longitudinal data from the Household, Income and Labour Dynamics in Australia Survey (93,367 observations from 17,893 individuals) were used to estimate conditional fixed effects logistic regression models of the likelihood of moderate or vigorous physical exercise for at least 30 min, at least four times a week. No significant associations between long working hours and the incidence of healthy levels of physical activity were uncovered once other exogenous influences on activity levels were controlled for. The odds of men or women who usually work 60 or more hours per week exercising at healthy levels were 6% and 11% less, respectively, than those of comparable persons working a more standard 35-40 h/week; however, neither estimate was significantly different from 0 at 95% CI. The findings suggest that there is no trade-off between long working hours and physical activity in Australia. It is argued that these findings are broadly consistent with previous research studies from Anglo-Saxon countries (where long working hours are pervasive) that employed large nationally representative samples.

  2. Definition of a Twelve-Point Polygonal SAA Boundary for the GLAST Mission

    International Nuclear Information System (INIS)

    Djomehri, Sabra I.; UC, Santa Cruz; SLAC

    2007-01-01

    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 ∼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 ∼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

    1995-01-01

    To evaluate the role of magnetic resonance imaging (MRI) and computed tomography (CT) in the diagnosis of intramuscular ganglia (IMG) that arise from the superior tibiofibular joint (STFJ). Our series consisted of three men and three women. Four patients were studied by MRI, one by CT only, and two by both modalities. Contrast was used in one of the two patients studied by CT. MRI was obtained in at least two orthogonal planes to demonstrate the relation of the ganglia to STFJ. The MR and CT appearance of these ganglia was basically that of a well-defined soft tissue mass with low attenuation on CT images consistent with the presence of fluid. On MR studies, they had an isointense signal on T1-weighted images and a homogenous high-intensity signal on T2-weighted images. MRI demonstrated the attachment of these ganglia to the STFJ. CT and MRI were effective, noninvasive modalities in the evaluation of IMG. The imaging features on both modalities were consistent with the presence of fluid-containing lesions that had close proximity and were attached to the STFJ. The combination of location and the fluid consistency of these lesions facilitated the diagnosis. (orig.)

    Intramuscular fat (IMF) content is an important determinant factor of meat quality in cattle. There is significant difference in IMF content between Jinnan and Simmental cattle. Here, to identify candidate genes and networks associated with IMF deposition, we deeply explored the transcriptome architecture of liver in these two cattle breeds. We sequenced the liver transcriptome of five Jinnan and three Simmental cattle, yielding about 413.9 million sequencing reads. 124 differentially expressed genes (DEGs) were detected, of which 53 were up-regulated and 71 were down-regulated in Jinnan cattle. 1282 potentially novel genes were also identified. Gene ontology analysis revealed these DEGs (including CYP21A2, PC, ACACB, APOA1, and FADS2) were significantly enriched in lipid biosynthetic process, regulation of cholesterol esterification, reverse cholesterol transport, and regulation of lipoprotein lipase activity. Genes involved in pyruvate metabolism pathway were also significantly overrepresented. Moreover, we identified an interaction network which related to lipid metabolism, which might be contributed to the IMF deposition in cattle. We concluded that the DEGs involved in the regulation of lipid metabolism could play an important role in IMF deposition. Overall, we proposed a new panel of candidate genes and interaction networks that can be associated with IMF deposition and used as biomarkers in cattle breeding. Copyright © 2017 Elsevier Inc.

    Isolated (localized) idiopathic granulomatous vasculitis (IGV) is an uncommon, heterogeneous, and poorly defined group of disorders characterized by infiltration of the arterial wall caused by compactly grouped mononuclear phagocytes, with or without giant cells, in segmental distribution. We report on a 55-year-old woman with IGV limited to an intramuscular lipoma of the left thigh. The vasculitis was identified incidentally upon microscopic examination of the removed tumor. The IGV was centered on two medium-sized arteries, accompanied by narrowing of the lumens, and not associated with secondary changes such as infart or postinfart fibrosis. The inflammatory infiltrate was rich in T-lymphocytes and macrophages, with the presence of giant cells. The patient was asymptomatic and well in a follow-up period of 2 months, during which she was not treated. To our knowledge, this is the first report of lipoma involvement in localized IGV. It is important to distinguish cases of isolated intratumorous IGV from systemic disease, because the latter implies a poor prognosis and requires an aggressive treatment.

    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.

    Full Text Available Intramuscular fat (IMF content is an important indicator for meat quality evaluation. However, the key genes and molecular regulatory mechanisms affecting IMF deposition remain unclear. In the present study, we identified 75 differentially expressed genes (DEGs between the higher (H and lower (L IMF content of pigs using transcriptome analysis, of which 27 were upregulated and 48 were downregulated. Notably, Kyoto Encyclopedia of Genes and Genomes (KEGG enrichment analysis indicated that the DEG perilipin-1 (PLIN1 was significantly enriched in the fat metabolism-related peroxisome proliferator-activated receptor (PPAR signaling pathway. Furthermore, we determined the expression patterns and functional role of porcine PLIN1. Our results indicate that PLIN1 was highly expressed in porcine adipose tissue, and its expression level was significantly higher in the H IMF content group when compared with the L IMF content group, and expression was increased during adipocyte differentiation. Additionally, our results confirm that PLIN1 knockdown decreases the triglyceride (TG level and lipid droplet (LD size in porcine adipocytes. Overall, our data identify novel candidate genes affecting IMF content and provide new insight into PLIN1 in porcine IMF deposition and adipocyte differentiation.

    The pharmacokinetics of enrofloxacin (ENR) was studied in crucian carp (Carassius auratus gibelio) after single administration by intramuscular (IM) injection and oral gavage (PO) at a dose of 10 mg/kg body weight and by 5 mg/L bath for 5 hr at 25°C. The plasma concentrations of ENR and ciprofloxacin (CIP) were determined by HPLC. Pharmacokinetic parameters were calculated based on mean ENR or CIP concentrations using WinNonlin 6.1 software. After IM, PO and bath administration, the maximum plasma concentration (C max ) of 2.29, 3.24 and 0.36 μg/ml was obtained at 4.08, 0.68 and 0 hr, respectively; the elimination half-life (T 1/2β ) was 80.95, 62.17 and 61.15 hr, respectively; the area under the concentration-time curve (AUC) values were 223.46, 162.72 and 14.91 μg hr/ml, respectively. CIP, an active metabolite of enrofloxacin, was detected and measured after all methods of drug administration except bath. It is possible and practical to obtain therapeutic blood concentrations of enrofloxacin in the crucian carp using IM, PO and bath immersion administration. © 2017 John Wiley & Sons Ltd.

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.

    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. © 2013.

    Kinetic variables for tiamulin in the normal dog have been determined. Serum concentrations of tiamulin were compared after intramuscular (i.m.) and subcutaneous (s.c.) administration of a single dose of tiamulin. Following a single i.m. dose of 10 mg/kg body weight, the compound was calculated to have a Cmax = 0.61 +/- 0.15 micrograms/ml, a Tmax = 6 h and a t1/2 = 4.7 +/- 1.4 h. Tiamulin showed dose-dependent pharmacokinetics when given as a single s.c. dose of either 10 mg or 25 mg/kg body weight. For the lower dose, the values Cmax = 1.55 +/- 0.11 micrograms/ml, Tmax = 8 h and t1/2 = 4.28 +/- 0.18 h were obtained. For the higher dose Cmax = 3.14 +/- 0.04 micrograms/ml, Tmax = 8 h and t1/2 = 12.4 +/- 3.4 h were calculated. When tiamulin was administered subcutaneously at a dose rate of 10 mg/kg body weight, higher and better maintained serum levels were achieved than those following i.m. administration. After repeated s.c. doses no significant accumulation of tiamulin occurred. Assuming that a continuous effective serum concentration is necessary throughout the course of therapy, these data would indicate that tiamulin should be given every 24 h.

    The study describes the pharmacokinetics and predicted efficacy of imipenem after intravenous (IV), intramuscular (IM) and subcutaneous (SC) administration to five adult cats at a dose of 5 mg/kg. Susceptibility to imipenem [minimum inhibitory concentration (MIC)] was determined for antimicrobial resistant Escherichia coli (n = 13) and staphylococci (n = 3) isolated from domestic cat infections (urinary system, skin and conjunctiva). Maximum plasma concentrations of imipenem were 13.45 µg/ml (IV), 6.47 µg/ml (IM) and 3.83 µg/ml (SC). Bioavailability was 93.18% (IM) and 107.90% (SC). Elimination half-lives for IV, IM and SC administration were 1.17, 1.44 and 1.55 h, respectively. All tested bacteria were susceptible to imipenem; MIC values were 0.03 µg/ml for Staphylococcus species and imipenem concentrations remained above a MIC of 0.5 µg/ml for approximately 4 h (IV and IM) and 9 h (SC). Imipenem would be predicted to be effective for the treatment of antimicrobial resistant bacterial infections in cats at a dosage of 5 mg/kg every 6-8 h (IV, IM), or longer for the SC route. However, clinical trials are mandatory to establish its efficacy and proper dosing.

    Full Text Available Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic, and tumor antigens has been reported to trigger protective immunity. The use of plasmid DNA vaccinations against many diseases has produced promising results in animal and human clinical trials; however, safety concerns about the use of DNA vaccines exist, such as the possibility of integration into the host genome, and elicitation of adverse immune responses. Methods: In this study, we examined the potential integration and bio-distribution of pcDNA3.1+PA, a new vaccine candidate with GenBank accession # EF550208, encoding the PA63 gene, in reproductive organs of mice; ovaries and uterus in female, and testis in male. Animals of both sexes were injected intramuscularly with pcDNA3.1+PA. Host genome integration and tissue distribution were examined using PCR and RT-PCR two times monthly for six months. Results: RT-PCR confirmed that pcDNA3.1+PA was not integrated into the host genome and did not enter reproductive organs. Conclusions: This finding has important implications for the use of pcDNA3.1+PA plasmid as a vaccine and opens new perspectives in the DNA vaccine area.

    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.

    Nitric oxide (NO) is a critical component of host defense against invading pathogens; however, its therapeutic utility is limited due to a lack of practical delivery systems. Recently, a NO-releasing nanoparticulate platform (NO-np) was shown to have in vitro broad-spectrum antimicrobial activity and in vivo pre-clinical efficacy in a dermal abscess model. To extend these findings, both topical (TP) and intralesional (IL) NO-np administration was evaluated in a MRSA intramuscular murine abscess model and compared with vancomycin. All treatment arms accelerated abscess clearance clinically, histologically, and by microbiological assays on both days 4 and 7 following infection. However, abscesses treated with NO-np via either route demonstrated a more substantial, statistically significant decrease in bacterial survival based on colony forming unit assays and histologically revealed less inflammatory cell infiltration and preserved muscular architecture. These data suggest that the NO-np may be an effective addition to our armament for deep soft tissue infections.

    Intramuscular fat (IMF) content is an important indicator for meat quality evaluation. However, the key genes and molecular regulatory mechanisms affecting IMF deposition remain unclear. In the present study, we identified 75 differentially expressed genes (DEGs) between the higher (H) and lower (L) IMF content of pigs using transcriptome analysis, of which 27 were upregulated and 48 were downregulated. Notably, Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated that the DEG perilipin-1 ( PLIN1 ) was significantly enriched in the fat metabolism-related peroxisome proliferator-activated receptor (PPAR) signaling pathway. Furthermore, we determined the expression patterns and functional role of porcine PLIN1. Our results indicate that PLIN1 was highly expressed in porcine adipose tissue, and its expression level was significantly higher in the H IMF content group when compared with the L IMF content group, and expression was increased during adipocyte differentiation. Additionally, our results confirm that PLIN1 knockdown decreases the triglyceride (TG) level and lipid droplet (LD) size in porcine adipocytes. Overall, our data identify novel candidate genes affecting IMF content and provide new insight into PLIN1 in porcine IMF deposition and adipocyte differentiation.

    Nine patients with chronic immune thrombocytopenia and platelet counts anti-D. Phase 1 was anti-D daily for 5 days, followed by phase 2, anti-D weekly for 12 weeks and withheld when platelet counts ≥ 20 × 10(9) /L, and then phase 3 was anti-D once every 2 weeks for 24 weeks. According to the International Working Group criteria, in phase 1, 66.7% of patients responded to the treatment. In phases 2 and 3, 11.1% (0-41.7%) and 7.7% (0-33.3%) of total episodes of follow up, respectively, responded to the treatment. Therefore, intramuscular anti-D given at a dose of 10 mcg/kg for 5 days is an alternative method to raise platelet counts in chronic immune thrombocytopenia children with severe thrombocytopenia where the intravenous form of anti-D is not available. © 2013 The Authors.

    Pharmacokinetic parameters of methadone were studied in adult dairy goats. Five goats were each given methadone hydrochloride as a single 0.2 mg/kg of body weight dosage by intramuscular (IM) administration. Plasma methadone concentrations were determined for 96 h after dosing. Plasma methadone concentrations after IM administration were best described by an open one-compartment model. Overall elimination half-life (t1/2) was 1.38 h. Peak plasma concentrations were reached 0.25 h after dosing, and the actual plasma concentration averaged 37.8 ng/ml (SD = 12.76) at that time. The data obtained from this study suggest that plasma concentrations, similar to those that are analgesic in humans, can be achieved after IM administration of methadone at a dose rate of 0.2 mg/kg of body weight. In addition, these plasma concentrations can be maintained for up to 3 h after a single injection and, therefore, may provide satisfactory analgesia for such period.

    Lower aerobic capacity is a strong and independent predictor of cardiovascular morbidity and mortality in patients with metabolic syndrome (MetS). However, the mechanisms are not fully elucidated. We tested the hypothesis that skeletal muscle dysfunction could contribute to the lower aerobic capacity in MetS patients. The incremental exercise tests with cycle ergometer were performed in 12 male patients with MetS with no habitual exercise and 11 age-, sex- and activity-matched control subjects to assess the aerobic capacity. We performed 31 phosphorus-magnetic resonance spectroscopy (MRS) to assess the high-energy phosphate metabolism in skeletal muscle during aerobic exercise. Proton-MRS was also performed to measure intramyocellular lipid (IMCL) content. Peak oxygen uptake (peak VO 2 ; 34.1±6.2 vs. 41.4±8.4 ml kg -1 min -1 , P -1 min -1 , P 2 (r=-0.64) and AT (r=-0.60), respectively. IMCL content was threefold higher in MetS and was inversely correlated with peak VO 2 (r=-0.47) and AT (r=-0.52), respectively. Moreover, there was a positive correlation between IMCL content and PCr loss (r=0.64). These results suggested that lean-body aerobic capacity in MetS patients was lower compared with activity-matched healthy subjects, which might be due to the reduced intramuscular fatty acid oxidative metabolism.

    The aim of the study was to describe the pharmacokinetics and predicted efficacy of meropenem after intravenous (IV), intramuscular (IM) and subcutaneous (SC) administration to cats at a single dose of 10 mg/kg. Five adult healthy cats were used. Blood samples were withdrawn at predetermined times over a 12 h period. Meropenem concentrations were determined by microbiological assay. Pharmacokinetic analyses were performed with computer software. Initial estimates were determined using the residual method and refitted by non-linear regression. The time that plasma concentrations were greater than the minimum inhibitory concentration (T >MIC) was estimated by applying bibliographic MIC values and meropenem MIC breakpoint. Maximum plasma concentrations of meropenem were 101.02 µg/ml (C p(0) , IV), 27.21 µg/ml (C max , IM) and 15.57 µg/ml (C max , SC). Bioavailability was 99.69% (IM) and 96.52 % (SC). Elimination half-lives for the IV, IM and SC administration were 1.35, 2.10 and 2.26 h, respectively. Meropenem, when administered to cats at a dose of 10 mg/kg q12h,, is effective against bacteria with MIC values of 6 μg/ml, 7 μg/ml and 10 μg/ml for IV, IM and SC administration, respectively. However, clinical trials are necessary to confirm clinical efficacy of the proposed dosage regimen. © The Author(s) 2015.

    Resistive exercise helps prevent muscle atrophy in microgravity, but better exercise equipment is needed. Therefore, the purpose of this study was to determine if a pneumatic, gravity-independent leg-press device (LPD) provides sufficient force to leg musculature. We hypothesized that intramuscular pressure (IMP), a quantitative index of muscle force, is greater in the antigravity superficial posterior and deep posterior compartments than in the non-antigravity anterior compartment during bilateral leg-press exercise. Millar pressure transducers were inserted into the anterior, lateral, superficial posterior, and deep posterior muscle compartments of the left leg of eight healthy subjects (three women, five men). Subjects were supine on the Keiser SX-1, a pneumatic LPD. Then maximal voluntary contraction (MVC) was determined; each subject performed three consecutive voluntary contractions at approximately 18%, 50%, and 100% MVC while continuously measuring IMP. Repeated measures ANOVA were used to determine differences of IMPs between compartments and loads. The magnitudes of IMP (mean +/- SEM) at 18 - 3% (abbreviated approximately 18%), 50%, and 100% MVC in the superficial and deep posterior compartments were significantly greater than that in the anterior compartment during exercise (P antigravity compartments as compared to the non-antigravity compartment. Since antigravity muscles of the leg are contained primarily in the superficial and deep posterior compartments, the LPD may help prevent muscle atrophy associated with microgravity.

    Castration increases intramuscular fat (IMF) deposition, improving beef quality in cattle. The present study was performed to determine the global transcriptome changes following castration of bulls and to identify genes associated with IMF deposition in the longissimus dorsi (LM) of Korean cattle. A customized bovine CombiMatrix oligonucleotide microarray was constructed, and transcriptome changes following castration were determined by microarray hybridization. Transcriptome comparison between bulls and steers indicated that 428 of 8,407 genes were differentially expressed in the LM by greater than two fold (P castration. Castration upregulated transcription of adipogenic perilipin 2 (PLIN2) and visfatin, lipogenic fatty acid synthase, fatty acid esterification 1-acylglycerol-3-phosphate O-acyltransferase 5, and many fatty acid oxidation-related genes. Many TCA cycle and OP genes were also transcriptionally upregulated. Correlation analysis indicated that the IMF content in the LM was highly correlated with mRNA levels of PLIN2 (r = 0.70, P castration shifts transcription of lipid metabolism genes, favoring IMF deposition by increasing adipogenesis, lipogenesis, and triglyceride synthesis. This study also indicated that castration increases transcription of genes involved in fatty acid oxidation and subsequent energy production (TCA and OP genes). Our microarray analysis provided novel information that castration alters the transcriptome associated with lipid/energy metabolism, favoring IMF deposition in the LM.

    IFNβ products and glatiramer acetate are established treatment first-line options in long-term disease-modifying therapy of multiple sclerosis (MS). These self-injectable medications are used once weekly to once daily. Injection-related issues are common patient-cited reasons for nonadherence. Autoinjectors have been shown to support long-term adherence to injectable medications. The ability to self-inject in MS patients has been associated with a reduced risk of missed injections and drug discontinuation, and a beneficial effect on patient independence. The recently introduced easy-to-use prefilled once-weekly pen is a safe and effective device for intramuscular (IM) IFNβ-1a application and provides a convenient method for self-injection. We reviewed the available published evidence on the characteristics of this device. The once-weekly pen facilitates self-injection and was preferred over prefilled syringes by patients in a prospective open-label, multicenter Phase IIIb trial in MS patients who had been using IM IFNβ-1a in prefilled syringes. The simple and safe handling, shielded short needle, single-use disposable design and virtually painless injection by the device may contribute to adherence, quality of life and independence in patients using IM IFNβ-1a.

    Full Text Available Objectives: To investigate the effects of air-lock technique (ALT on pain of intramuscular (IM injection delivered to the ventrogluteal and dorsogluteal site (DS. Methods: A randomized controlled trial design was used to assess the pain intensity associated with IM injections administered using 2 different methods and injection sites. Recruitment of patients was carried out between April and August 2013 at the Department of Brain Surgery, Cekirge State Hospital, Bursa, Turkey. The sample comprised 60 patients who developed no complications at the IM site, and had no illness that could affect their perception of pain. The patients were randomly divided into 2 groups of 30 patients. Patients in the first group received injections in the ventrogluteal site (VS, while the DS was used for injections in the second group. Patients in each group received 2 injections, one using ALT and one not using the technique. After each injection, the pain felt by patients during the injection was immediately assessed using a visual analog scale. Results: The mean pain score after injections to the DS by the ALT was 3.30 ± 2.70, while the mean pain score after injections to the VS using the same technique was 2.53 ± 2.52. Conclusion: Although the difference between groups was not significant, the results of the study supported the idea that injections delivered to the VS by ALT are less painful than those delivered to the DS.

    Testosterone is an anabolic androgenic steroid (AAS) that is endogenously produced by both male and female horses that also has the potential for abuse when administered exogenously to race horses. To recommend appropriate withdrawal guidelines so that veterinarians can discontinue therapeutic use prior to competition, the pharmacokinetics and elimination of testosterone were investigated. An aqueous testosterone suspension was administered intramuscularly in the neck of Thoroughbred horses (n = 20). The disposition of testosterone from this formulation was characterized by an initial, rapid absorption phase followed by a much more variable secondary absorption phase. The median terminal half-life was 39 h. A second focus of this study was to compare the testosterone concentrations determined by two different laboratories using a percentage similarity model with a coefficient of variation of 16.5% showing good agreement between the two laboratories results. Based on the results of this study, a withdrawal period of 30 days for aqueous testosterone administered IM is recommended. © 2011 Blackwell Publishing Ltd.

    Full Text Available 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.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(OHD concentrations were measured in all individuals at defined time points throughout the studies.The mean 25(OHD 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(OHD 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(OHD serum concentrations after 28 days was comparable between both routes of administration (p = 0.264.Oral and intramuscular cholecalciferol supplementation effectively increased serum 25(OHD concentrations.

    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.

    Legal bar closing times in England and Wales have historically been early and uniform. Recent legislation liberalised closing times with the object of reducing social problems thought associated with drinking to "beat the clock." Indeed, using both difference in difference and synthetic control approaches we show that one consequence of this liberalisation was a decrease in traffic accidents. This decrease is heavily concentrated among younger drivers. Moreover, we provide evidence that the effect was most pronounced in the hours of the week directly affected by the liberalisation: late nights and early mornings on weekends. This evidence survives a series of robustness checks and suggests at least one socially positive consequence of extending bar hours. Copyright © 2014 Elsevier B.V. All rights reserved.

    Lipodystrophy syndrome associated with highly active antiretroviral therapy (HAART) may lead to low self-esteem and poor compliance with the drug treatment on patients infected with human immunodeficiency virus (HIV), which is a matter of concern for the health system. The aim of this study was to evaluate patients with HIV submitted to gluteal augmentation with intramuscular silicone implants to correct gluteal lipoatrophy related to the use of HAART. This is a retrospective evaluation of 10 patients submitted to gluteal augmentation with intramuscular silicone implant for correction of gluteal lipoatrophy related to the use of HAART, operated between 2012 and 2015. Postoperative complications and the degree of patient's satisfaction were analyzed. There were 3 postoperative complications including 1 case of surgical wound dehiscence and 2 cases of seroma. Six months after surgery, 8 patients had an excellent degree of satisfaction, and 2 patients had a good degree of satisfaction related to the procedure. Although this intervention does not offer functional advantages, it improves the body contour, increases patients' self-esteem, and helps them to accept their body image. These advantages can lead to higher compliance with prolonged HAART. Gluteal augmentation with intramuscular silicone implant can be a viable option to treat patients with HIV with gluteal lipoatrophy related to the use of HAART. The patients were satisfied with the outcomes of the procedure, and there were only minor self-limited postoperative complications.

    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.

  13. Twelve fundamental life histories evolving through allocation-dependent fecundity and survival.

    An organism's life history is closely interlinked with its allocation of energy between growth and reproduction at different life stages. Theoretical models have established that diminishing returns from reproductive investment promote strategies with simultaneous investment into growth and reproduction (indeterminate growth) over strategies with distinct phases of growth and reproduction (determinate growth). We extend this traditional, binary classification by showing that allocation-dependent fecundity and mortality rates allow for a large diversity of optimal allocation schedules. By analyzing a model of organisms that allocate energy between growth and reproduction, we find twelve types of optimal allocation schedules, differing qualitatively in how reproductive allocation increases with body mass. These twelve optimal allocation schedules include types with different combinations of continuous and discontinuous increase in reproduction allocation, in which phases of continuous increase can be decelerating or accelerating. We furthermore investigate how this variation influences growth curves and the expected maximum life span and body size. Our study thus reveals new links between eco-physiological constraints and life-history evolution and underscores how allocation-dependent fitness components may underlie biological diversity.

    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. 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. 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.

    Does working time causally affect workers' health? We study this question in the context of a French reform which reduced the standard workweek from 39 to 35 hours, at constant earnings. Our empirical analysis exploits variation in the adoption of this shorter workweek across employers, which is mainly driven by institutional features of the reform and thus exogenous to workers' health. Difference-in-differences and lagged dependent variable regressions reveal a negative effect of working hou...

    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.

  17. 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.

    Despite modern treatment approaches and a focus on community care, there remains a group of people who cannot easily be discharged from psychiatric hospital directly into the community. Twenty-four hour residential rehabilitation (a 'ward-in-a-house') is one model of care that has evolved in association with psychiatric hospital closure programmes. To determine the effects of 24 hour residential rehabilitation compared with standard treatment within a hospital setting. We searched the Cochrane Schizophrenia Group Trials Register (May 2002 and February 2004). We included all randomised or quasi-randomised trials that compared 24 hour residential rehabilitation with standard care for people with severe mental illness. Studies were reliably selected, quality assessed and data extracted. Data were excluded where more than 50% of participants in any group were lost to follow-up. For binary outcomes we calculated the relative risk and its 95% confidence interval. We identified and included one study with 22 participants with important methodological shortcomings and limitations of reporting. The two-year controlled study evaluated "new long stay patients" in a hostel ward in the UK. One outcome 'unable to manage in the placement' provided usable data (n=22, RR 7.0 CI 0.4 to 121.4). The trial reported that hostel ward residents developed superior domestic skills, used more facilities in the community and were more likely to engage in constructive activities than those in hospital - although usable numerical data were not reported. These potential advantages were not purchased at a price. The limited economic data was not good but the cost of providing 24 hour care did not seem clearly different from the standard care provided by the hospital - and it may have been less. From the single, small and ill-reported, included study, the hostel ward type of facility appeared cheaper and positively effective. Currently, the value of this way of supporting people - which could be

    Thirty-one nonheparinized patients with suspected deep venous thrombophlebitis (DVT) underwent contrast venography and indium-111 platelet scintigraphy (In-111 PS). Venography permitted identification of acute DVT in 12 of 31 cases (39%). One additional patient was considered to have acute DVT despite nonconclusive venography results. In-111 PS results were positive at 4 hours in nine of 13 cases (69%) and at 24 hours in 12 of 13 cases (92%). Two of four patients with false-negative 4-hour In-111 PS studies had received warfarin. Thus, the sensitivity of 4-hour In-111 PS in patients not receiving anticoagulants was 82%. Venography results were negative for acute DVT in 18 cases, and 4-hour In-111 PS studies were negative or equivocal in each. In-111 PS is an alternative to contrast venography for detecting acute DVT. If 4-hour In-111 PS results are positive, anticoagulation can be initiated. Delayed images are necessary if the 4-hour images are negative or equivocal

  1. Operator alertness and performance on 8-hour and 12-hour work shifts

    International Nuclear Information System (INIS)

    Baker, T.L.; Campbell, S.S.; Dawson, D.; Moore-Ede, M.

    1989-01-01

    Recently, much attention has been paid to the alertness and performance problems of rotational shiftworkers in the nuclear power industry. Growing awareness of higher rates of human errors and accidents on night shifts and reports of operations personnel falling asleep on the job have contributed to the heightened interest in this subject. The industry is now considering the effects of different shift rotation systems, including evaluation of the most recent of industry trends in shift scheduling-schedules that include 12 hour work shifts. Surveys show that within the past 5 years about 20% of commercially operational nuclear power plants have instituted schedules that use only 12 hour shifts, or schedules using a combination of 8-hour and 12-hour shifts. Many more plants routinely use 12-hour work shifts during plant outages and refueling operations. In response to this growing trend, the NRC has funded research which is a first attempt to compare alertness, operator performance, and sleep-wake patterns in subjects working simulated 8-hour and 12-hour shifts at the Human Alertness Research Center (HARC), located at the Institute of Circadian Physiology in Boston, MA. This paper will describe in greater detail the design of the study, measurement techniques for alertness and sleep, work routine, work task performance measures, and cognitive performance test protocols. It will review the role of circadian factors in human alertness and performance, and discuss previous research findings in this area. It will discuss other variables that are known to influence human alertness in the workplace, such as caffeine, alcohol, and working environment. The physiological basis for shift worker sleep problems will be explained in the context of the ongoing research project at HARC. Finally, the paper presents previous research on shift work and fatigue which may be relevant to a comparison of 8-hour and 12-hour shifts

    Increases in standard hours of work have been a contentious policy issue in Germany. Whilst this might directly lead to a substitution of workers by hours, there may also be a positive employment effect due to reduced costs. Moreover, the response of firms may differ between firms that offer overtime and those that do not. For a panel of German plants (2001–2006) drawn from the IAB Establishment Panel, we are the first to analyse the effect of increased standard hours on employment. Using dif...

  4. Gene expression in the muscle and central nervous system following intramuscular inoculation of encapsidated or naked poliovirus replicons

    2003-01-01

    The spread of intramuscularly inoculated poliovirus to the central nervous system (CNS) has been documented in humans, monkeys, and mice transgenic for the human poliovirus receptor. Poliovirus spread is thought to be due to infection of the peripheral nerve and retrograde transport of poliovirus through the axon to the neuron cell body, where final virus uncoating occurs and translation/replication ensues. In previous studies, we have shown that polio-based vectors (replicons) can be used for gene delivery to motor neurons of the CNS. Using a replicon that encodes green fluorescent protein (GFP), we found that following intrathecal inoculation, GFP expression was confined to motorneurons of the spinal cord. To further characterize the gene expression of poliovirus in the periphery and CNS, we have intramuscularly inoculated transgenic mice with poliovirus replicons encoding GFP. Expression of GFP was demonstrated in the muscle, sciatic nerve, dorsal root ganglion, and the ventral horn motorneurons following intramuscular inoculation. There was no evidence of paralysis or behavioral abnormalities in the mice following intramuscular inoculation of the replicon encoding GFP. Injection of replicon RNA alone (naked RNA) into the muscle of transgenic mice or rats, which do not express the poliovirus receptor, also resulted in expression of GFP in the muscle, sciatic nerve, dorsal root ganglion, and ventral horn motorneurons, indicating that transport of the replicon RNA from the periphery to CNS had occurred. GFP expression was found in the muscles and sciatic nerve as early as 6 h after injection of replicons or replicon RNA, even after sciatic nerve section. Analysis at longer times postinjection revealed GFP expression similar to 6 h levels in the cut sciatic nerves and robust expression in the nerves of uncut animals. The infection and expression of GFP in the CNS following intramuscular inoculation of encapsidated replicons encoding GFP occurred in juvenile or

    To evaluate the pharmacokinetics of nalbuphine decanoate after IM administration to Hispaniolan Amazon parrots (Amazona ventralis). 9 healthy adult Hispaniolan Amazon parrots of unknown sex. Nalbuphine decanoate (37.5 mg/kg) was administered IM to all birds. Plasma samples were obtained from blood collected before (time 0) and 0.25, 1, 2, 3, 6, 12, 24, 48, and 96 hours after drug administration. Plasma samples were used for measurement of nalbuphine concentrations via liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were estimated with computer software. Plasma concentrations of nalbuphine increased rapidly after IM administration, with a mean concentration of 46.1 ng/mL at 0.25 hours after administration. Plasma concentrations of nalbuphine remained > 20 ng/mL for at least 24 hours in all birds. The maximum plasma concentration was 109.4 ng/mL at 2.15 hours. The mean terminal half-life was 20.4 hours. In Hispaniolan Amazon parrots, plasma concentrations of nalbuphine were prolonged after IM administration of nalbuphine decanoate, compared with previously reported results after administration of nalbuphine hydrochloride. Plasma concentrations that could be associated with antinociception were maintained for 24 hours after IM administration of 37.5 mg of nalbuphine decanoate/kg. Safety and analgesic efficacy of nalbuphine treatments in this species require further investigation to determine the potential for clinical use in pain management in psittacine species.

  6. The twelve-flavor β-function and dilaton tests of the sextet scalar

    Directory of Open Access Journals (Sweden)

    Fodor Zoltan

    2018-01-01

    Full Text Available We discuss near-conformal gauge theories beyond the standard model (BSM where interesting results on the twelve-flavor β-function of massless fermions in the fundamental representation of the SU(3 color gauge group and dilaton tests of the light scalar with two massless fermions in the two-index symmetric tensor (sextet representation can be viewed as parts of the same BSM paradigm under investigation. The clear trend in the decreasing size of β-functions at fixed renormalized gauge coupling is interpreted as a first indicator how the conformal window (CW is approached in correlation with emergent near-conformal light scalars. BSM model building close to the CW will be influenced by differing expectations on the properties of the emergent light 0++ scalar either as a σ-particle of chiral symmetry breaking (ΧS B, or as a dilaton of scale symmetry breaking. The twelve-flavor β-function emerges as closest to the CW, perhaps near-conformal, or perhaps with an infrared fixed point (IRFP at some unexplored strong coupling inside the CW. It is premature to speculate on dilaton properties of the twelveflavor model since the near-conformal realization remains an open question. However, it is interesting and important to investigate dilaton tests of the light sextet scalar whose β-function is closest to the CW in the symmetry breaking phase and emerges as the leading candidate for dilaton tests of the light scalar. We report results from high precision analysis of the twelve-flavor β-function [1] refuting its published IRFP [2, 3]. We present our objections to recent claims [4, 5] for non-universal behavior of staggered fermions used in our analysis. We also report our first analysis of dilaton tests of the light 0++ scalar in the sextet model and comment on related post-conference developments. The dilaton test is the main thrust of this conference contribution including presentation #405 on the nf = 12 β-function and presentation #260 on dilaton

  10. Work shift duration: a review comparing eight hour and 12 hour shift systems.

    Science.gov (United States)

    Smith, L; Folkard, S; Tucker, P; Macdonald, I

    1998-04-01

    Shiftwork is now a major feature of working life across a broad range of industries. The features of the shift systems operated can impact on the wellbeing, performance, and sleep of shiftworkers. This paper reviews the current state of knowledge on one major characteristic of shift rotas-namely, shift duration. Evidence comparing the relative effects of eight hour and 12 hour shifts on fatigue and job performance, safety, sleep, and physical and psychological health are considered. At the organisational level, factors such as the mode of system implementation, attitudes towards shift rotas, sickness absence and turnover, overtime, and moonlighting are discussed. Manual and electronic searches of the shiftwork research literature were conducted to obtain information on comparisons between eight hour and 12 hour shifts. The research findings are largely equivocal. The bulk of the evidence suggests few differences between eight and 12 hour shifts in the way they affect people. There may even be advantages to 12 hour shifts in terms of lower stress levels, better physical and psychological wellbeing, improved durations and quality of off duty sleep as well as improvements in family relations. On the negative side, the main concerns are fatigue and safety. It is noted that a 12 hour shift does not equate with being active for only 12 hours. There can be considerable extension of the person's time awake either side of the shift. However, the effects of longer term exposure to extended work days have been relatively uncharted in any systematic way. Longitudinal comparative research into the chronic impact of the compressed working week is needed.

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.

    This study assessed the diagnostic accuracy of a novel 24-hour ambulatory blood pressure (ABP) monitor (Microlife WatchBP O3 Afib) with implemented algorithm for automated atrial fibrillation (AF) detection during each ABP measurement. One hundred subjects (mean age 70.6±8.2 [SD] years; men 53%; hypertensives 85%; 17 with permanent AF; 4 paroxysmal AF; and 79 non-AF) had simultaneous 24-hour ABP monitoring and 24-hour Holter monitoring. Among a total of 6410 valid ABP readings, 1091 (17%) were taken in ECG AF rhythm. In reading-to-reading ABP analysis, the sensitivity, specificity, and accuracy of ABP monitoring in detecting AF were 93%, 87%, and 88%, respectively. In non-AF subjects, 12.8% of the 24-hour ABP readings indicated false-positive AF, of whom 27% were taken during supraventricular premature beats. There was a strong association between the proportion of false-positive AF readings and that of supraventricular premature beats ( r =0.67; P ABP monitoring had 100%/85% sensitivity/specificity (area under the curve 0.91; P ABP monitor with AF detector has high sensitivity and moderate specificity for AF screening during routine ABP monitoring. Thus, in elderly hypertensives, a 24-hour ABP recording with at least 26% of the readings suggesting AF indicates a high probability for AF diagnosis and should be regarded as an indication for performing 24-hour Holter monitoring. © 2018 American Heart Association, Inc.

  17. Relationship between medical compression and intramuscular pressure as an explanation of a compression paradox.

    2015-06-01

    Using standing magnetic resonance imaging (MRI), we recently showed that medical compression, providing an interface pressure (IP) of 22 mmHg, significantly compressed the deep veins of the leg but not, paradoxically, superficial varicose veins. To provide an explanation for this compression paradox by studying the correlation between the IP exerted by medical compression and intramuscular pressure (IMP). In 10 legs of five healthy subjects, we studied the effects of different IPs on the IMP of the medial gastrocnemius muscle. The IP produced by a cuff manometer was verified by a Picopress® device. The IMP was measured with a 21G needle connected to a manometer. Pressure data were recorded in the prone and standing positions with cuff manometer pressures from 0 to 50 mmHg. In the prone position, an IP of less than 20 did not significantly change the IMP. On the contrary, a perfect linear correlation with the IMP (r = 0.99) was observed with an IP from 20 to 50 mmHg. We found the same correlation in the standing position. We found that an IP of 22 mmHg produced a significant IMP increase from 32 to 54 mmHg, in the standing position. At the same time, the subcutaneous pressure is only provided by the compression device, on healthy subjects. In other words, the subcutaneous pressure plus the IP is only a little higher than 22 mmHg-a pressure which is too low to reduce the caliber of the superficial veins. This is in accordance with our standing MRI 3D anatomical study which showed that, paradoxically, when applying low pressures (IP), the deep veins are compressed while the superficial veins are not. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

One single-dose, randomized, three-way, crossover relative bioavailability study and one linearity single escalating dose, randomized, three-way cross-over pharmacokinetic study were conducted at two different clinical sites. A total of 42 healthy male and female subjects participated in both studies. Subjects received 75 mg/ml diclofenac sodium HPβCD (i.m. and s.c.) and Voltaren® 75 mg/3 ml (i.m.) in Study 1 and 25, 50, or 75 mg/ml diclofenac sodium HPβCD (s.c.) in Study 2. Study 1 demonstrated bioequivalence of the s.c. test formulation with Voltaren® i.m. with respect to Cmax and AUC. Bioequivalence of the test i.m. with Voltaren® i.m. was also demonstrated (except the upper limit of the 90% confidence interval (CI) for Cmax which marginally exceeded the 80 - 125% range (125.78%)). Study 2 demonstrated that after s.c. administration of the test formulation, both Cmax and AUC are linearly related to the tested diclofenac doses. All tested doses were safe and locally well-tolerated with no serious adverse events reported. Bioequivalence of diclofenac HPβCD 75 mg/ml after s.c. and i.m. administration with Voltaren® i.m. was demonstrated, except for the marginal deviation in Cmax when comparing the i.m. test and Voltaren®. Linearity was also demonstrated for the three doses intended for marketing.

    The metabolism of cefmenoxime (SCE-1365) was studied in four healthy male volunteers after intramuscular administration of a single 500-mg dose of the 14C-labeled drug. Plasma levels of total radioactivity and cefmenoxime peaked at 0.5 and 1.0 h, corresponding to 16.5 micrograms eq/ml and 15.8 micrograms/ml, respectively. Thereafter, parent drug levels declined rapidly, with a terminal elimination half-life of ca. 1.5 h. No significant differences were noted between total radioactivity and parent drug levels up to 2 h after drug administration. After 3 h, low but persistent levels of radioactivity were significantly greater than parent drug levels, indicating metabolism or degradation of cefmenoxime. The terminal elimination half-life of total radioactivity was estimated to be ca. 40 h. The radioactive plasma metabolite(s) remaining at the end of the 5-day study represented only 1% of the administered dose. Urinary excretion was the major route of elimination of cefmenoxime, accounting for ca. 86% of the dose in 12 h. Analysis of cefmenoxime in urine by total radioactivity, high-pressure liquid chromatography, and a microbiological assay showed that 80 to 92% of the excreted dose was parent drug. Radioactivity was also excreted into the feces via the bile and represented ca. 11% of the dose after 5 days. Although extensive degradation of cefmenoxime was found in fecal samples, it was proposed that this may be due to the metabolic activity of the intestinal flora rather than in vivo biotransformation in the liver. This study supports the concept that cefmenoxime undergoes minimal metabolism in humans and is excreted largely as unchanged drug

    Full Text Available The current study was designed to probe pathological effects of colistin in growing broilers. One hundred twenty day-old broiler chicks were divided into six equal groups A-F. These birds were injected colistin sulphate, 0, 5, 10, 20, 40 and 80 mg/kg BW respectively through intramuscular route. The different serum-biochemical parameters including total protein, albumen, globulin, ALT, AST, LDH, GGT, creatinine and BUN were determined at day 21 and 42 of experiment. The hematological parameters including RBC, WBC, PCV and Hb were determined twice. The serum total protein values were significantly higher in group E as compared with control group. At day 42 groups, C-E had significantly lower albumen values as compared to group A. The similar pattern was observed in globulin values. The creatinine & urea was also found significantly higher in group D and E at day 21 of experiment, while at day 42 all the groups having significantly higher urea level in comparison with group A indicating nephrotoxic effect of colistin. The serum enzymes including ALT and AST were significantly higher in group D & E as compared with group A, which is an indication of liver damage. The LDH and GGT values showed significantly increasing trend in experimental groups compared with control. The erythrocytes and leucocytes count were significantly higher in control and low dose groups as compared with higher colistin dose groups. It is concluded that lavish parenteral administration of colistin resulted in increased levels of hepato-renal serum indicators and lower values of hematological parameters.

    Post partum hemorrhage still remains a major cause of maternal morbidity and mortality in developing countries. Most of oxytocics like methylergometrine require parenteral administration, which requires special storage. Misoprostol is thermo stable, has a long shelf life and is widely recommended for prevention of postpartum hemorrhage. This can be a choice of oxytocic in developing countries like ours, where storage facilities and resources are limited. Objectives: To compare efficacy of sublingual Misoprostol versus intramuscular Methylergometrine in prevention of primary postpartum hemorrhage after delivery. Study Design: Quasi experimental study Place and Duration of Study: Department of Gynae/Obs, Military Hospital and Combined Military Hospital Rawalpindi cantt. December 2007 to July 2008. Material and Methods: One hundred and thirty six pregnant ladies were selected. On arrival each patient was examined thoroughly along with baseline investigations. Therapeutic option was allocated to the patients simply by using a table of random numbers and dividing them in two equal groups. Informed written consent was taken. Each patient was observed for blood loss estimation and hematocrit drop. All the data was analyzed using SPSS version 10.0. Mean +- SD for age, pre-delivery and post-delivery hematocrit, percentage of drop in hematocrit and blood loss during labour was calculated. Results: Mean drop of hematocrit and blood loss were compared among two groups. At the end, it was revealed that there was no significant difference among two groups in blood loss (p=0.49) and hematocrit drop (p=0.14). Conclusion: There is no significant better effect in preventing post partum hemorrhage among the two drugs. (author)

    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.

    Full Text Available Abstract Background Acute behavioural disturbance (ABD is an increasing problem in emergency departments. This study aimed to determine the impact of a structured intramuscular (IM sedation protocol on the duration of ABD in the emergency department. Methods A historical control study was undertaken comparing 58 patients who required physical restraint and parenteral sedation with the structured IM sedation protocol, to 73 historical controls treated predominantly by intravenous sedation, according to individual clinician preference. The primary outcome was the duration of the ABD defined as the time security staff were required. Secondary outcomes were the requirement for additional sedation, drug related-adverse effects and patient and staff injuries. Results The median duration of the ABD in patients with the new sedation protocol was 21 minutes (IQR: 15 to 35 minutes; Range: 5 to 78 minutes compared to a median duration of 30 minutes (IQR: 15 to 50 minutes; Range: 5 to 135 minutes in the historical controls which was significantly different (p = 0.03. With IM sedation only 27 of 58 patients (47%; 95% CI: 34% to 60% required further sedation compared to 64 of 73 historical controls (88%; 95%CI: 77% to 94%. There were six (10% drug-related adverse events with the new IM protocol [oxygen desaturation (5, oxygen desaturation/airway obstruction (1] compared to 10 (14% in the historical controls [oxygen desaturation (5, hypoventilation (4 and aspiration (1]. Injuries to staff occurred with three patients using the new sedation protocol and in seven of the historical controls. Two patients were injured during the new protocol and two of the historical controls. Conclusion The use of a standardised IM sedation protocol was simple, more effective and as safe for management of ABD compared to predominantly intravenous sedation.

    Abstract Background: Uterine niche is defined as a triangular anechoic structure at the site of the scar or a gap in the myometrium at the site of a previous caesarean section. The main clinical manifestations are postmenstrual spotting and intrauterine infection, which may seriously affect the daily life of nonpregnant women. Trials have shown an excellent safety and efficacy for the potential of mesenchymal stem cells (MSCs) as a therapeutic option for scar reconstruction. Therefore, this study is designed to investigate the safety and efficacy of using MSCs in the treatment for the uterine niche. Methods/design: This phase II clinical trial is a single-center, prospective, randomized, double-blind, placebo-controlled with 2 arms. One hundred twenty primiparous participants will be randomly (1:1 ratio) assigned to receive direct intramuscular injection of MSCs (a dose of 1∗107 cells in 1 mL of 0.9% saline) (MSCs group) or an identical-appearing 1 mL of 0.9% saline (placebo-controlled group) near the uterine incision. The primary outcome of this trial is to evaluate the proportion of participants at 6 months who is found uterine niche in the uterus by transvaginal utrasonography. Adverse events will be documented in a case report form. The study will be conducted at the Department of Obstetric of Southern Medical University Affiliated Maternal & Child Health Hospital of Foshan. Discussion: This trial is the first investigation of the potential for therapeutic use of MSCs for the management of uterine niche after cesarean delivery. Conclusion: This protocol will help to determine the efficacy and safety of MSCs treatment in uterine niche and bridge the gap with regards to the current preclinical and clinical evidence.

    Fenneropenaeus chinensis, an economically important shrimp species, currently suffers from epizootic diseases due to high density stocking and bacterial infections. Oxytetracycline (OTC) has been widely used to treat various systemic bacterial infections in shrimp farming. In the present study, the effect of gender on pharmacokinetics of OTC in F. chinensis was investigated. The OTC concentrations in hemolymph of shrimp after single intramuscular administration (75 mg OTC per kg body weight) were analyzed by high performance liquid chromatography and best described with a two-compartment open model which is characterized by a short elimination half-life, low clearance, and a relatively large apparent volume of distribution. The pharmacokinetic equations were C t = 58.54e-0.38 t + 11.67e-0.04 t for females; and C t = 27.94e-0.28 t + 14.87e-0.04 t for males. The distribution and elimination half-lives of OTC were 1.82 and 19.58 h, respectively, in females and 2.50 and 16.11 h, respectively, in males at 22°C. The areas under the drug concentration curve were 480 mg L-1 h-1 in females and 430 mg L-1 h-1 in males. The total body clearance of the drug was 157.11 mL kg-1 h-1 in females and 172.47 mL kg-1 h-1 in males. The apparent volume distribution was 4.44 in females and 4.01 L kg-1 in males. There was no significant difference in pharmacokinetic parameters between female and male shrimps, indicating that there is no need to consider the gender effect in clinical use of OTC in F. chinensis farming.

    Drug treatment of severe malaria must be rapidly effective. Suppositories may be valuable for childhood malaria when circumstances prevent oral or parenteral therapy. We compared artesunate suppositories (n = 41; 8 to 16 mg/kg of body weight at 0 and 12 h and then daily) with intramuscular (i.m.) artemether (n = 38; 3.2 mg/kg at 0 h and then 1.6 mg/kg daily) in an open-label, randomized trial with children with severe Plasmodium falciparum malaria in Papua New Guinea (PNG). Parasite density and temperature were measured every 6 h for ≥72 h. Primary endpoints included times to 50% and 90% parasite clearance (PCT50 and PCT90) and the time to per os status. In a subset of 29 patients, plasma levels of artemether, artesunate, and their common active metabolite dihydroartemisinin were measured during the first 12 h. One suppository-treated patient with multiple complications died within 2 h of admission, but the remaining 78 recovered uneventfully. Compared to the artemether-treated children, those receiving artesunate suppositories had a significantly earlier mean PCT50 (9.1 versus 13.8 h; P = 0.008) and PCT90 (15.6 versus 20.4 h; P = 0.011). Mean time to per os status was similar for each group. Plasma concentrations of primary drug plus active metabolite were significantly higher in the artesunate suppository group at 2 h postdose. The earlier initial fall in parasitemia with artesunate is clinically advantageous and mirrors higher initial plasma concentrations of active drug/metabolite. In severely ill children with malaria in PNG, artesunate suppositories were at least as effective as i.m. artemether and may, therefore, be useful in settings where parenteral therapy cannot be given.

    To assess quality of sedation following intramuscular (IM) injection of two doses of alfaxalone in combination with butorphanol in cats. Prospective, randomized, 'blinded' clinical study. A total of 38 cats undergoing diagnostic imaging or noninvasive procedures. Cats were allocated randomly to be administered butorphanol 0.2 mg kg -1 combined with alfaxalone 2 mg kg -1 (group AB2) or 5 mg kg -1 (group AB5) IM. If sedation was inadequate, alfaxalone 2 mg kg -1 IM was administered and cats were excluded from further analysis. Temperament [1 (friendly) to 5 (aggressive)], response to injection, sedation score at 2, 6, 8, 15, 20, 30, 40, 50 and 60 minutes, overall sedation quality scored after data collection [1 (excellent) to 4 (inadequate)] and recovery quality were assessed. Heart rate (HR), respiratory rate (f R ) and arterial haemoglobin saturation (SpO 2 ) were recorded every 5 minutes. Groups were compared using t tests and Mann-Whitney U tests. Sedation was analysed using two-way anova, and additional alfaxalone using Fisher's exact test (p cats in AB2 and two in AB5 (p = 0.005). Recovery quality, HR, f R and SpO 2 were similar. Seven cats required oxygen supplementation. Complete recovery times were shorter in AB2 (81.8 ± 24.3 versus 126.6 ± 33.3 minutes; p = 0.009). Twitching was the most common adverse event. In combination with butorphanol, IM alfaxalone at 5 mg kg -1 provided better quality sedation than 2 mg kg -1 . Monitoring of SpO 2 is recommended.

    The pharmacological effects of the anesthetic alfaxalone were evaluated after intramuscular (IM) administration to 6 healthy beagle dogs. The dogs received three IM doses each of alfaxalone at increasing dose rates of 5 mg/kg (IM5), 7.5 mg/kg (IM7.5) and 10 mg/kg (IM10) every other day. Anesthetic effect was subjectively evaluated by using an ordinal scoring system to determine the degree of neuro-depression and the quality of anesthetic induction and recovery from anesthesia. Cardiorespiratory variables were measured using noninvasive methods. Alfaxalone administered IM produced dose-dependent neuro-depression and lateral recumbency (i.e., 36 ± 28 min, 87 ± 26 min and 115 ± 29 min after the IM5, IM7.5 and IM10 treatments, respectively). The endotracheal tube was tolerated in all dogs for 46 ± 20 and 58 ± 21 min after the IM7.5 and IM10 treatments, respectively. It was not possible to place endotracheal tubes in 5 of the 6 dogs after the IM5 treatment. Most cardiorespiratory variables remained within clinically acceptable ranges, but hypoxemia was observed by pulse oximetry for 5 to 10 min in 2 dogs receiving the IM10 treatment. Dose-dependent decreases in rectal temperature, respiratory rate and arterial blood pressure also occurred. The quality of recovery was considered satisfactory in all dogs receiving each treatment; all the dog exhibited transient muscular tremors and staggering gait. In conclusion, IM alfaxalone produced a dose-dependent anesthetic effect with relatively mild cardiorespiratory depression in dogs. However, hypoxemia may occur at higher IM doses of alfaxalone.

    The pharmacokinetic properties and tissue distribution of enrofloxacin (EF) were investigated after single intramuscular (i.m.) dose of 10 mg/kg body weight (b.w.) in Pacific white shrimp at 22 to 25°C. EF and its metabolite ciprofloxacin (CF) were determined by high-performance liquid chromatography. After i.m. administration, EF was absorbed quickly, and the peak of EF concentration (C max ) reached at first time point in hemolymph. The volume of distribution V d(area) of EF was 3.84 L/kg, indicating that the distribution of EF was good. The area under the concentration-time curve (AUC) of EF was 90.1 and 274.2 μg hr/ml in muscle and hepatopancreas, respectively, which was higher than 75.8 μg hr/ml in hemolymph. The EF elimination was slow in muscle and hepatopancreas with the half-life (T 1/2β ) of 52.3 and 75.8 hr, respectively. CF, the mainly metabolite of EF, was detected in hemolymph, muscle and hepatopancreas. The C max was 0.030, 0.013 and 0.218 μg/ml, respectively. Based on a minimum inhibitory concentration (MIC) of 0.006-0.032 μg/ml for susceptible strains, EF i.m. injected at a dose 10 mg/kg could be efficacious against common pathogenic bacteria of Pacific white shrimp. © 2017 John Wiley & Sons Ltd.

    Working hours in Australia are quite widely distributed around the population mean. That is, there are relatively many people working both relatively short hours and relatively long hours each week. From a welfare perspective, however, it is not the actual number of hours worked that is of importance, but whether the hours being worked are consistent with individual preferences. In this paper the question of how closely hours preferences are being met is examined using data collected in the f...

    As time and cost constraints in the conduct of systematic reviews increase, the need to consider the use of existing systematic reviews also increases. We developed guidance on the integration of systematic reviews into new reviews. A workgroup of methodologists from Evidence-based Practice Centers developed consensus-based recommendations. Discussions were informed by a literature scan and by interviews with organizations that conduct systematic reviews. Twelve recommendations were developed addressing selecting reviews, assessing risk of bias, qualitative and quantitative synthesis, and summarizing and assessing body of evidence. We provide preliminary guidance for an efficient and unbiased approach to integrating existing systematic reviews with primary studies in a new review. Copyright © 2016 Elsevier Inc.

    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.

    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.

    To find the longitudinal genetic effects on mandibular position in mixed dentition. The sample used in this study consisted of lateral cephalograms of eighty-nine pairs of female twins in Beijing. With a mixed longitudinal method, the effective twins were 183 pairs(monozygous 110 pairs and dizygous 73 ones). The genetic and environmental effects on mandibular position were analyzed by statistical methods in female twins from six to twelve years old. Statistical comparisons revealed significant (Pchin is the most subjective to environment change, then the mandibular angle, and the condyle is the least. Using N and S as references, the environmental influence on heights showed different order from the most to least changeable: The mandibular angle, the condyle and the chin. In later stage of our observation, the mandibular morphology and growth type might be family inherited. For environmental influences plays important roles on mandibular position, these findings can be used in orthodontic treatment planning.

    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.

    A suite of tetra-, penta-, and hexa-nucleotide microsatellite loci were developed from Roche 454 pyrosequencing data for the cold-water octocorals Primnoa resedaeformis and P. pacifica. Twelve of 98 primer sets tested consistently amplified in 30 P. resedaeformis samples from Baltimore Canyon (western North Atlantic Ocean) and in 24 P. pacifica samples (Shutter Ridge, eastern Gulf of Alaska). The loci displayed moderate levels of allelic diversity (average 7.5 alleles/locus) and heterozygosity (average 47 %). Levels of genetic diversity were sufficient to produce unique multi-locus genotypes and to distinguish species. These common species are long-lived (hundreds of years) and provide essential fish habitat (P. pacifica), yet populations are provided little protection from human activities. These loci will be used to determine regional patterns of population connectivity to inform effective marine spatial planning and ecosystem-based fisheries management.

    Child development is a marker of well-being in childhood and recognition of developmental delay allows timely investigation and intervention for children with developmental disabilities. Despite this, child development and disabilities are not given emphasis in the medical curriculum. This under representation of teaching combined with the stigma associated with disabilities contributes to the sub-optimal health care of people with disabilities. As well as, addressing the stigma of disability a medical undergraduate curriculum should include: the key concepts of child development; the clinical presentation of the most common developmental disabilities; developmental history taking and the infant neurodevelopmental examination. The following twelve tips provide practical advice about how to teach this knowledge and these skills during medical training.

    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.

    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...

    The authors aggregated the results of observational studies examining the association between long working hours and coronary heart disease (CHD). Data sources used were MEDLINE (through January 19, 2011) and Web of Science (through March 14, 2011). Two investigators independently extracted results from eligible studies. Heterogeneity between the studies was assessed using the I2 statistic, and the possibility of publication bias was assessed using the funnel plot and Egger's test for small-study effects. Twelve studies were identified (7 case-control, 4 prospective, and 1 cross-sectional). For a total of 22,518 participants (2,313 CHD cases), the minimally adjusted relative risk of CHD for long working hours was 1.80 (95% confidence interval (CI): 1.42, 2.29), and in the maximally (multivariate-) adjusted analysis the relative risk was 1.59 (95% CI: 1.23, 2.07). The 4 prospective studies produced a relative risk of 1.39 (95% CI: 1.12, 1.72), while the corresponding relative risk in the 7 case-control studies was 2.43 (95% CI: 1.81, 3.26). Little evidence of publication bias but relatively large heterogeneity was observed. Studies varied in size, design, measurement of exposure and outcome, and adjustments. In conclusion, results from prospective observational studies suggest an approximately 40% excess risk of CHD in employees working long hours. PMID:22952309

    Background Tennis elbow is an overuse injury affecting people performing repetitive forearm movements. It is a soft tissue disorder that causes significant disability and pain. The aim of the study was to establish that an intramuscular steroid injection is effective in the short-term pain relief and functional improvement of tennis elbow. The severity of pain at the injection site was monitored to determine whether the intramuscular injection is better tolerated than the intralesional injection. Methods and results 19 patients, who had no treatment for tennis elbow in the preceding 3 months, were recruited from Whipps Cross University Hospital, London, and were randomised to receive either 80 mg of intramuscular Depo-Medrone or 40 mg of intralesional Depo-Medrone injection. Blinding proved difficult as the injection sites differed and placebo arms were not included in the study. A Patient-Rated Tennis Elbow Evaluation (PRTEE) Questionnaire and a 10-point Likert scale were used to assess primary outcome. Six weeks after the treatment, there was a reduction in pain, improvement in function and total PRTEE scores in both intramuscular and intralesional groups (p=0.008) using a 95% CI for mean treatment difference of −26 to +16 points. A statistically significant result (p=0.001) in favour of intramuscular causing less pain at the injection site was noted. Conclusion Non-inferiority of intramuscular to intralesional injections was not confirmed; however, the intramuscular injection proved to be effective in reducing tennis elbow-related symptoms and was found less painful at the site of injection at the time of administration.

    Violent patients in the prehospital environment pose a threat to health care workers tasked with managing their medical conditions. While research has focused on methods to control the agitated patient in the emergency department (ED), there is a paucity of data looking at the optimal approach to subdue these patients safely in the prehospital setting. Hypothesis This study evaluated the efficacy of two different intramuscular medications, midazolam and haloperidol, to determine their efficacy in sedating agitated patients in the prehospital setting. This was a prospective, randomized, observational trial wherein agitated patients were administered intramuscular haloperidol or intramuscular midazolam to control agitation. Agitation was quantified by the Richmond Agitation and Sedation Scale (RASS). Paramedics recorded the RASS and vital signs every five minutes during transport and again upon arrival to the ED. The primary outcome was mean time to achieve a RASS less than +1. Secondary outcomes included mean time for patients to return to baseline mental status and adverse events. Five patients were enrolled in each study group. In the haloperidol group, the mean time to achieve a RASS score of less than +1 was 24.8 minutes (95% CI, 8-49 minutes), and the mean time for the return of a normal mental status was 84 minutes (95% CI, 0-202 minutes). Two patients required additional prehospital doses for adequate sedation. There were no adverse events recorded in the patients administered haloperidol. In the midazolam group, the mean time to achieve a RASS score of less than +1 was 13.5 minutes (95% CI, 8-19 minutes) and the mean time for the return of normal mental status was 105 minutes (95% CI, 0-178 minutes). One patient required additional sedation in the ED. There were no adverse events recorded among the patients administered midazolam. Midazolam and haloperidol administered intramuscularly appear equally effective for sedating an agitated patient in the

    To evaluate single- and repeated-dose pharmacokinetics (PK) and dose proportionality of hydroxypropyl-β-cyclodextrin (HPβCD)-diclofenac compared with Voltarol after intravenous (IV) and intramuscular (IM) administration. Study 1: Single-dose randomized four-way crossover study. Study 2: Multiple-dose randomized three-way crossover study. Clinical research center. Healthy adult volunteers. Study 1: Subjects received HPβCD-diclofenac and Voltarol, IV and IM, with a 5-day washout between treatment periods. Study 2: Subjects received two doses of IV HPβCD-diclofenac and oral Cataflam once every 6 hours for four doses with a 48-hour washout period between treatment periods. Study 1: IV HPβCD-diclofenac had a higher peak plasma concentration (Cmax ) and earlier time to reach maximum plasma concentration (Tmax ), but equivalent plasma exposure (area under the curve from time zero to t [AUC0-t ]) to IV Voltarol. The geometric mean ratio of HPβCD-diclofenac (IV) to Voltarol (IV) for AUC0-t was 106.27%. The geometric mean ratio of HPβCD-diclofenac (IM) to Voltarol (IM) for AUC0-t was 110.91%. The geometric mean ratio of HPβCD-diclofenac (IV) to HPβCD-diclofenac (IM) for AUC0-t was 101.25%. The geometric mean ratio of HPβCD-diclofenac (IM) to Voltarol (IV) for AUC0-t was 104.96%. Study 2: Cmax for diclofenac was 2904 and 6031 ng/ml after the first IV dose of 18.75 and 37.5 mg HPβCD-diclofenac, respectively, and was 3090 and 5617 ng/ml after the fourth dose, indicating no accumulation. Plasma exposures to 18.75 mg (866 ng·hour/ml) and 37.5 mg (1843 ng·hour/ml) IV HPβCD-diclofenac bracketed that of oral Cataflam 50 mg (1473 ng·hour/ml). Study 1: Bioavailability in terms of AUC after IV administration was equivalent for HPβCD-diclofenac compared with Voltarol and after IM administration of HPβCD-diclofenac and Voltarol. Bioavailability in terms of AUC after IM administration of HPβCD-diclofenac was equivalent to IV administration of HP

    Full Text Available The skeletal muscle develops various degrees of atrophy and metabolic dysfunction following nerve injury. Neurotrophic factors are essential for muscle regeneration. Human amniotic fluid derived stem cells (AFS have the potential to secrete various neurotrophic factors necessary for nerve regeneration. In the present study, we assess the outcome of neurological function by intramuscular injection of AFS in a muscle denervation and nerve anastomosis model.Seventy two Sprague-Dawley rats weighing 200-250 gm were enrolled in this study. Muscle denervation model was conducted by transverse resection of a sciatic nerve with the proximal end sutured into the gluteal muscle. The nerve anastomosis model was performed by transverse resection of the sciatic nerve followed by four stitches reconnection. These animals were allocated to three groups: control, electrical muscle stimulation, and AFS groups.NT-3 (Neurotrophin 3, BDNF (Brain derived neurotrophic factor, CNTF (Ciliary neurotrophic factor, and GDNF (Glia cell line derived neurotrophic factor were highly expressed in AFS cells and supernatant of culture medium. Intra-muscular injection of AFS exerted significant expression of several neurotrophic factors over the distal end of nerve and denervated muscle. AFS caused high expression of Bcl-2 in denervated muscle with a reciprocal decrease of Bad and Bax. AFS preserved the muscle morphology with high expression of desmin and acetylcholine receptors. Up to two months, AFS produced significant improvement in electrophysiological study and neurological functions such as SFI (sciatic nerve function index and Catwalk gait analysis. There was also significant preservation of the number of anterior horn cells and increased nerve myelination as well as muscle morphology.Intramuscular injection of AFS can protect muscle apoptosis and likely does so through the secretion of various neurotrophic factors. This protection furthermore improves the nerve

    Full Text Available Objectives: This experiment was conducted to examine the toxicity of WCF (Water soluble Carthmi-Flos herbal acupuncture by administering a single intramuscular dose of WCF in 6-week-old, male and female Sprague-Dawley rats and to find the lethality dose for WCF. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices under a request by the Korean Pharmacopuncture Institute. This experiment was performed based on the testing standards of “Toxicity Test Standards for Drugs” by the Ministry of Food and Drug Safety. Subjects were divided into 4 groups: 1 control group in which normal saline was administered and 3 test groups in which 0.1, 0.5 or 1.0 mL of WCF was administered; a single intramuscular dose was injected into 5 males and 5 females in each group. General symptoms and body weights were observed/measured for 14 days after injection. At the end of the observation period, hematological and clinical chemistry tests were performed, followed by necropsy and histopathological examinations of the injected sections. Results: No mortalities were observed in any group. Also, symptoms, body weight, hematology, clinical chemistry and necropsy were not affected. However, histopathological examination of the injected part in one female in the 1.0-mL group showed infiltration of mononuclear cells and a multi-nucleated giant cell around eosinophilic material. Conclusion: Administration of single intramuscular doses of WCF in 3 groups of rats showed that the approximate lethal dose of WCF for all rats was in excess of 1.0 mL, as no mortalities were observed for injections up to and including 1.0 mL.

    A scintigraphic technique employing technetium pyrophosphate uptake was used to identify the area of skeletal muscle damage in the lower leg of four runners 24 h after an ultramarathon footrace (160 km). Most of the race had been run downhill which incorporated an extensive amount of eccentric work. Soreness was diffuse throughout the posterior region of the lower leg. In order to interpret what increased technetium uptake reflects and to express extreme endurance related damages, a biopsy was taken from the 3-D position of abnormal uptake. In addition, intramuscular pressures were determined in the deep posterior compartment. Scintigraphs revealed increased technetium pyrophosphate uptake in the medial portion of the gastrocnemius muscle. For 3698 fibres analysed, 33 fibres (1%) were necrotic, while a few other fibres were either atrophic or irregular shaped. A cluster of necrotic fibres occurred at the fascicular periphery for one subject and fibre type grouping occurred for another. Ultrastructural analysis revealed Z-line streaming near many capillaries and variously altered subsarcolemmal mitochondria including some with paracrystalline inclusions. The majority of the capillaries included thickened and irregular shaped endothelial cells. Intramuscular pressures of the deep posterior compartment were slightly elevated (12-15 mmHg) for three of the four subjects. Increased technetium uptake following extreme endurance running does not just reflect muscle necrosis but also subtle fibre abnormalities. Collectively, these pathological findings are attributed to relative ischaemia occurring during the race and during pre-race training, whereas, intramuscular pressure elevations associated with muscle soreness are attributed to mechanical stress caused by extensive eccentric work during the race.

    To analyze intramuscular soft-tissue tumors with fatty rind, and to evaluate the difference between fatty rind and split fat sign on magnetic resonance imaging (MRI). We retrospectively analyzed 50 pathologically confirmed intramuscular masses on MRI. We evaluated the distribution and shape of fatty rind and muscle atrophy. Fatty rind was found more frequently in benign lesions (80% [36 out of 45]) compared with malignant lesions (25% [1 out of 5]; P = 0.013). Thirty-six benign lesions were peripheral nerve sheath tumors (PNSTs; n = 19), hemangiomas (n = 11), myxomas (n = 2), ganglion cysts (n = 2), giant cell tumor (n = 1), and leiomyoma (n = 1). One malignant lesion was a low-grade fibromyxoid sarcoma. In all masses with fatty rind, fat was confined to the proximal and the distal ends. In 12 cases, complete or partial circumferential fatty rind was also noted. Fatty rinds at both ends showed crescent, triangular, or combined shape. The prevalence of crescent-shaped fatty rind was significantly higher in benign PNST (17 out of 38) compared with the other tumors (1 out of 32; P < 0.001). Complete circumferential fat was noted only in hemangioma (n = 5). Triangular fatty rind was related to peripheral location of the mass or muscle atrophy. Most intramuscular tumors with fatty rinds were benign, and PNST was the most common tumor type. Fatty rind could be caused by displaced neurovascular bundle fat, fatty atrophy of the muscle involved, or intermuscular or perimysial fat. Crescent-shaped fatty rind was noted more frequently in benign PNSTs. (orig.)

    Mycoplasma hyopneumoniae (M. hyopneumoniae) vaccine strain 168 is an intrapulmonically injected attenuated live vaccine that is available in the Chinese market. The aim of this study was to develop suitable adjuvants for this live vaccine to provide effective protection after intramuscular inoculation. Several adjuvant components were screened to assess their toxicity for the live vaccine, and various adjuvant formulations were then designed and prepared. Vaccines supplemented with these adjuvants were used to immunize mice intramuscularly to assess the capacity of the adjuvants to induce a specific immune response. The screened formulations were then evaluated in pigs. Seven of the eight adjuvant components did not affect the viability of the live vaccine, and seven different adjuvant formulations were then designed. In mice, the ISCOM-matrix adjuvant and the levamisole-chitosan mixture adjuvant significantly enhanced serum IgG responses against M. hyopneumoniae, while lymphocyte proliferation was enhanced by the ISCOM-matrix adjuvant, the carbomer-astragalus polysaccharide mixture adjuvant and an oil-in-water emulsion adjuvant. These four adjuvants were evaluated in pigs. Enhancement of specific lymphocyte proliferation responses was observed in the groups vaccinated with the ISCOM-matrix adjuvant and the carbomer-astragalus polysaccharide mixture adjuvant. Significant enhancement of serum IgG antibody production was observed before challenge in pigs vaccinated with the carbomer-astragalus polysaccharide mixture adjuvant and the levamisole-chitosan mixture adjuvant, while after challenge, all of the animals that received vaccines containing adjuvants had higher antibody concentrations against M. hyopneumoniae than unvaccinated animals. Animals inoculated with a vaccine containing the ISCOM-matrix adjuvant (median score 3.57) or the carbomer-astragalus polysaccharide mixture adjuvant (median score 5.28) had reduced lesion scores compared to unvaccinated animals

    Development of prodrug of 9-hydroxyrisperidone (paliperidone) long-acting intramuscular injection has enabled delivery over four-week time period with improved compliance. The key aim of this work was to establish a reliable preclinical model which may potentially serve as a screening tool for judging the pharmacokinetics of paliperidone formulation(s) prior to human clinical work. Sparse sampling composite study was used in rats, (Wistar/Sprague-Dawley (SD; n = 10)) and a serial blood sampling study design was used in rabbits (n = 4). Animals received intramuscular injection of paliperidone palmitate in the thigh muscle at dose of 16 (rats) and 4.5 mg/kg (rabbits). Samples were drawn in rats (retro-orbital sinus) and rabbits (central ear artery) and were analysed for paliperidone using liquid chromatography-mass spectrometry/ mass spectrometry (LC-MS/MS) assay. The plasma data was subjected to pharmacokinetic analysis. Following intramuscular injection of depot formulation in Wistar/SD rats and rabbits, absorption of paliperidone was slow and gradual with median value of time to reach maximum concentration (T max ) occurring on day 7. The exposures (i.e. area under the curve (AUC; 0-28) days) were 18,597, 21,865 and 18,120 ng.h/mL, in Wistar, SD and rabbits, respectively.

    Flexible work hours, including 12-hour shifts, have become a common scheduling option for nurses. The author explores whether 12-hour shifts are an ethical scheduling option for nurses because recent research suggests that 12-hour shifts are a potential hazard to patients. A multistep model for ethical decision making, reflecting the concept of procedural justice, is used to examine this issue.

    The present study sought to evaluate the effect of a change from a rotating 3-shift (8-hour) to a 2-shift shift (12 hour) schedule on sleep, sleepiness, performance, perceived health, and well-being. Thirty-two shift workers at a chemical plant (control room operators) responded to a questionnaire a few months before a change was made in their shift schedule and 10 months after the change. Fourteen workers also filled out a diary, carried activity loggers, and carried out reaction-time tests (beginning and end of shift). Fourteen day workers served as a reference group for the questionnaires and 9 were intensively studied during a week with workdays and a free weekend. The questionnaire data showed that the shift change increased satisfaction with workhours, sleep, and time for social activities. Health, perceived accident risk, and reaction-time performance were not negatively affected. Alertness improved and subjective recovery time after night work decreased. The quick changes in the 8-hour schedule greatly increased sleep problems and fatigue. Sleepiness integrated across the entire shift cycle showed that the shift workers were less alert than the day workers, across workdays and days off (although alertness increased with the 12-hour shift). The change from 8-hour to 12-hour shifts was positive in most respects, possibly due to the shorter sequences of the workdays, the longer sequences of consecutive days off, the fewer types of shifts (easier planning), and the elimination of quick changes. The results may differ in groups with a higher work load.

Sedation was scored 3 times (every 10 minutes after drugs administration using a descriptive sedation scale (0 = no sedation, 13 = extremely sedated. Induction was performed at T30 with titrate-to-effect propofol and the dosage was recorded. Student T-test was performed. Weight, age, temperament, body temperature and propofol dose were not different between groups. At each time point, excluding T0, IM-group showed a statistically lower HR and fRcompared to IN-group. No undesirable effects were observed in both groups. Sedation score in IM-group was significantlyhigher compared to IN-group at each time point. In conclusion, despite statistical differences, IN administration produces a satisfactory clinical sedation with more gradual hemodynamic effects compared to IM injection; this is probably due to a direct transport of drugs from cranial nerves (I-V to brain with limited systemic absorption. However, the high variability recorded in sedation score between subjects in IN-group (min 1/13; max 13/13 at T30

    1. Adiponectin and its receptors (ADIPOR1 and ADIPOR2) are novel endocrine systems that act at various levels to modulate glucose and lipid metabolism. This study was designed to investigate the spatial expression of adiponectin, ADIPOR1 and ADIPOR2 genes in various tissues in Tibetan chicken. The temporal expression of adiponectin and its receptor mRNAs were also studied in adipose tissue, breast muscle and thigh muscle and the correlations of the levels of adiponectin, ADIPOR1 and ADIPOR2 mRNA with the contents of intramuscular fat in breast muscle and thigh muscle of Tibetan chicken were determined. 2. Quantitative real-time PCR detected chicken adiponectin, ADIPOR1 and ADIPOR2 mRNA transcripts in heart, liver, spleen, lung, kidney, skeletal muscle and adipose tissue. 3. Adipose tissue contained the highest amount of adiponectin mRNA followed by the kidney and liver. The expression levels of ADIPOR1 mRNA were significantly higher in adipose tissue, lung and spleen, and adipose tissue exhibited significantly higher levels of ADIPOR2 mRNA followed by the spleen and lung compared with other tissues. 4. Temporal expression profiles of adiponectin, ADIPOR1 and ADIPOR2 mRNA showed gender differences in adipose tissue and skeletal muscle at certain ages. In adipose tissue, adiponectin mRNA was higher in 154-d-old females and ADIPOR1 mRNA was higher in 154-d-old males: Adiponectin and ADIPOR2 mRNA were higher, and ADIPOR1 mRNA was lower, in thigh muscle in female compared with male chickens. 5. The correlation data showed that, except for adiponectin mRNA, the levels of ADIPOR1 and ADIPOR2 mRNA in thigh muscle of males were significantly positively correlated with IMF (r = 0.206 for the ADIPOR1 gene and r = 0.676 for the ADIPOR2 gene). 6. Taken together, it was concluded that adiponectin and the ADIPOR1 and ADIPOR2 genes are ubiquitously expressed in various tissues of Tibetan chicken and the expression of the adiponectin system is gender-dependant at certain ages

    What happens on the last day of a massive stars life? In the hours before the star collapses and explodes as a supernova, the rapid evolution of material in its core creates swarms of neutrinos. Observing these neutrinos may help us understand the final stages of a massive stars life but theyve never been detected.A view of some of the 1,520 phototubes within the MiniBooNE neutrino detector. Observations from this and other detectors are helping to illuminate the nature of the mysterious neutrino. [Fred Ullrich/FNAL]Silent Signposts of Stellar EvolutionThe nuclear fusion that powers stars generates tremendous amounts of energy. Much of this energy is emitted as photons, but a curious and elusive particle the neutrino carries away most of the energy in the late stages of stellar evolution.Stellar neutrinos can be created through two processes: thermal processesand beta processes. Thermal processes e.g.,pair production, in which a particle/antiparticle pair are created depend on the temperature and pressure of the stellar core. Beta processes i.e.,when a proton converts to a neutron, or vice versa are instead linked to the isotopic makeup of the stars core. This means that, if we can observe them, beta-process neutrinos may be able to tell us about the last steps of stellar nucleosynthesis in a dying star.But observing these neutrinos is not so easilydone. Neutrinos arenearly massless, neutral particles that interact only feebly with matter; out of the whopping 1060neutrinos released in a supernova explosion, even the most sensitive detectors only record the passage of just a few. Do we have a chance of detectingthe beta-process neutrinos that are released in the final few hours of a stars life, beforethe collapse?Neutrino luminosities leading up to core collapse. Shortly before collapse, the luminosity of beta-process neutrinos outshines that of any other neutrino flavor or origin.

    To evaluate the comparative effect of topical versus intramuscular administration of nanoparticle-carried DNA vaccine in preventing corneal herpes simplex virus type 1 (HSV-1) infection. Nanoparticle [polyethylenimine (PEI)-Fe3O4]-carried DNA vaccine (PEI-Fe3O4-pRSC-gD-IL-21) or DNA vaccine (pRSC-gD-IL-21) alone were topically versus intramuscularly inoculated into one eye each of mice on days 0, 14 and 28. Three weeks after the final immunization, the specific immune responses and clinical degrees of primary herpes simplex keratitis were evaluated. Topical inoculation of nanoparticle-carried DNA vaccine induced mice to generate similar levels of specific HSV-1-neutralizing antibody, IFN-γ and IL-4 in serum and specific killing (cytotoxicity) and proliferative activities of the splenic lymphocytes, but a significantly higher level of secretory IgA in tears compared to those of intramuscular inoculation. More importantly, the mice inoculated topically showed a significantly decreased herpes simplex keratitis severity than the mice inoculated intramuscularly after HSV-1 challenge on the corneas of the mice. Topical inoculation of nanoparticle-carried DNA vaccine elicits a stronger specific local immune response and more effectively inhibits herpes simplex keratitis as compared to intramuscular inoculation in an HSV-1 ocular challenge mouse model. Thus, topical administration may be a promising inoculating route for the nanoparticle-carried DNA vaccine to prevent corneal infections. © 2015 S. Karger AG, Basel.

    To determine the pharmacokinetics of ceftiofur sodium after IM and SC administration in green iguanas. 6 male and 4 female adult green iguanas. In a crossover design, 5 iguanas received a single dose of ceftiofur sodium (5 mg/kg) IM, and 5 iguanas received the same dose SC. Blood samples were taken at 0, 20, and 40 minutes and 1, 2, 4, 8, 24, 48, and 72 hours after administration. After a 10-week washout period, each iguana was given the same dose via the reciprocal administration route, and blood was collected in the same fashion. Ceftiofur free-acid equivalents were measured via high-performance liquid chromatography. The first phase intercepts were significantly different between the 2 administration routes. Mean maximum plasma concentration was significantly higher with the IM (28.6 +/- 8.0 microg/mL) than the SC (18.6 +/- 8.3 microg/mL) administration route. There were no significant differences between terminal half-lives (harmonic mean via IM route, 15.7 +/- 4.7 hours; harmonic mean via SC route, 19.7 +/- 6.7 hours) and mean areas under the curve measured to the last time point (IM route, 11,722 +/- 7,907 microg x h/mL; SC route, 12,143 +/- 9,633 microg x h/mL). Ceftiofur free-acid equivalent concentrations were maintained > or = 2 microg/mL for > 24 hours via both routes. A suggested dosing schedule for ceftiofur sodium in green iguanas for microbes susceptible at > 2 microg/mL would be 5 mg/kg, IM or SC, every 24 hours.

    Full Text Available Objective: To evaluate antimicrobial activities in methanolic extracts of twelve sponges collected from the Anambas Islands, Indonesia. Methods: The antibacterial activity of methanolic extracts was tested against two Grampositive bacteria, viz. Bacillus subtilis (ATCC 6633 and Staphylococcus aureus (ATCC 25923, and two Gram-negative bacteria, viz. Eschericia coli (ATCC 25922 and Vibrio anguillarum (ATCC 19264 using the disk diffusion assay. The antifungal activity was similarly tested against Candida albicans (ATCC 10231 and Aspergillus niger (ATCC 16404. The minimum inhibitory concentrations of promising sponges extracts were determined by the microdilution technique. Results: All the sponge species in this study showed antimicrobial activities against at least one of the test strains. Antibacterial activities were observed in 66.7% of the sponges extracts, while 30.0% of the extracts exhibited antifungal activities. Among them, the extracts of the sponges Stylissa massa and Axinyssa sp. were the most active against four tested bacteria and the yeast Candida albicans. The sponge Theonella swinhoei and two species of Xestospongia also displayed significant activities against two fungal pathogens Candida albicans and Aspergillus niger. Conclusions: Antimicrobial activities were demonstrated in extracts from various marine sponges collected from the Anambas Islands, Indonesia. The most promising sponges among them were Stylissa massa and Axinyssa sp. This is the first report of antimicrobial activity in extracts of marine sponges from the Indonesian Anambas Islands.

    Full Text Available Animal activists and environmental activists believe that the world and its inhabitants face devastating consequences in the future if behaviour towards and the treatment of animals and the environment do not change. However, despite their predictions many people are not swayed to change their behaviour. This article suggests that these activists experience what is known as Kassandra’s dilemma; the conundrum of knowing what the future holds but being unable to prevent events from happening. Drawing on the film, Twelve Monkeys and Greek mythology this article explores this mythological dilemma and explains how this dilemma is a lived experience for activists. The article suggests that activists can resolve Kassandra’s dilemma by taking a transdisciplinary approach towards animal and environmental activism. Thus, in order to escape Kassandra’s dilemma the article suggests that animal and environmental activists require transdisciplinary knowledge; knowledge of the actual and potential harm done to animals and the environment and how this can be prevented as well as knowledge on how to successfully convey this knowledge to others. The article highlights innovation diffusion theory as an example of the type of transdisciplinary knowledge that could assist in escaping from Kassandra’s dilemma and in order to better advocate on behalf of animals and the environment.

    To estimate the impact of onset of stress urinary incontinence in first pregnancy or postpartum period, for the risk of symptoms 12 years after the first delivery. In a longitudinal cohort study, 241 women answered validated questions about stress urinary incontinence after first delivery and 12 years later. Twelve years after first delivery the prevalence of stress urinary incontinence was 42% (102 of 241). The 12-year incidence was 30% (44 of 146). The prevalence of stress urinary incontinence 12 years after first pregnancy and delivery was significantly higher (Ppregnancy (56%, 37 of 66) and in women with onset shortly after delivery (78%, 14 of 18) compared with those without initial symptoms (30%, 44 of 146). In 70 women who had onset of symptoms during first pregnancy or shortly after the delivery but remission 3 months postpartum, a total of 40 (57%) had stress urinary incontinence 12 years later. In 11 women with onset of symptoms during the first pregnancy or shortly after delivery but no remission 3 months postpartum, a total of 10 (91%) had stress urinary incontinence 12 years later. Cesarean during first delivery was significantly associated with a lower risk of incontinence. Other obstetric factors were not significantly associated with the risk of incontinence 12 years later. Patients who were overweight before their first pregnancy were at increased risk. Onset of stress urinary incontinence during first pregnancy or puerperal period carries an increased risk of long-lasting symptoms.

    This paper describes a high-energy, twelve-channel laser facility (DELFIN) intended for high-temperature heating of thermonuclear targets with spherical symmetry. The facility includes a neodymium-glass laser with the ultimate radiation energy of 10 kJ, a pulse length of approximately 10 -10 to 10 -9 s, beam divergence of 5 x 10 -4 radians, a vacuum chamber in which laser radiation interacts with the plasma, and a system of diagnostic instrumentation for the observation of laser beam and plasma parameters. Described are the optical scheme and construction details of the laser facility. Presented is an analysis of focusing schemes for target irradiation and described is the focusing scheme of the DELFIN facility, which is capable of attaining a high degree of spherical symmetry in irradiating targets with maximum beam intensity at the target surface of approximately 10 15 W/cm 2 . This paper examines the most important problems connected with the physical investigations of thermonuclear laser plasma and the basic diagnostic problems involved in their solution

    Background Stability of personality disorders is assumed in most nomenclatures; however, the evidence for this is limited and inconsistent. The aim of this study is to investigate the stability of DSM-III personality disorders in a community sample of eastern Baltimore residents unselected for treatment. Methods Two hundred ninety four participants were examined on two occasions by psychiatrists using the same standardized examination twelve to eighteen years apart. All the DSM-III criteria for personality disorders were assessed. Item-response analysis was adapted into two approaches to assess the agreement between the personality measures on the two occasions. The first approach estimated stability in the underlying disorder, correcting for error in trait measurement, and the second approach estimated stability in the measured disorder, without correcting for item unreliability. Results Five of the ten personality disorders exhibited moderate stability in individuals: antisocial, avoidant, borderline, histrionic, and schizotypal. Associated estimated ICCs for stability of underlying disorder over time ranged between approximately 0.4 and 0.7–0.8. A sixth disorder, OCPD, exhibited appreciable stability with estimated ICC of approximately 0.2–0.3. Dependent, narcissistic, paranoid, and schizoid disorders were not demonstrably stable. Conclusions The findings suggest that six of the DSM personality disorder constructs themselves are stable, but that specific traits within the DSM categories are both of lesser importance than the constructs themselves and require additional specification.

    Following the works of Ford et al. and Steffen et al. we derived the transit timing of 1960 Kepler objects of interest (KOIs) using the pre-search data conditioning light curves of the first twelve quarters of the Kepler data. For 721 KOIs with large enough signal-to-noise ratios, we obtained also the duration and depth of each transit. The results are presented as a catalog for the community to use. We derived a few statistics of our results that could be used to indicate significant variations. Including systems found by previous works, we have found 130 KOIs that showed highly significant times of transit variations (TTVs) and 13 that had short-period TTV modulations with small amplitudes. We consider two effects that could cause apparent periodic TTV—the finite sampling of the observations and the interference with the stellar activity, stellar spots in particular. We briefly discuss some statistical aspects of our detected TTVs. We show that the TTV period is correlated with the orbital period of the planet and with the TTV amplitude.

    2002-03-07

    At the Department of Community Medicine at Lund University we have given courses in basic research methodology since 1989. The course has yielded 20 points of university credit, the equivalent of one full-time semester of studies, and it has been run part-time, covering one and a half years. Our aim has been to provide a large number of physicians with basic training in research methods, and to stimulate the engagement of new scientific students from the whole Southern Health Care Region. During the first ten years, 138 general practitioners (20% of the GPs of the region) and 202 specialists completed our courses. Up till now, 19 GPs (14%) and 19 specialists (9%) have begun PhD studies. During the last two years, another 100 physicians from southern Sweden have attended our courses, as well as GPs from Zealand in Denmark. We have been developing our course in basic research methods during a twelve-year period, and it is now well established in our health care region. We feel that we have succeeded in reaching the two goals we had set up: to give a large number of physicians a fundamental knowledge of research methods and to recruit and increase the number of PhD students. We believe that medical research and development must flourish also outside the traditional university settings.

    The Advanced Camera for Surveys (ACS) has been a workhorse HST imager for over twelve years, subsequent to its Servicing Mission 3B installation. The once defunct ACS Wide Field Channel (WFC) has now been operating longer since its Servicing Mission 4 repair than it had originally operated prior to its 2007 failure. Despite the accumulating radiation damage to the WFC CCDs during their long stay in low Earth orbit, ACS continues to be heavily exploited by the HST community as both a prime and a parallel detector. Conspicuous examples include the recently completed HST Multi-cycle Treasury programs, and the ongoing HST Frontier Fields (HFF) program.We review recent developments in ACS calibration that enable the continued high performance of this instrument, with particular attention the to the Wide Field Channel. Highlights include: 1) the refinement of the WFC geometric distortion solution and its time dependency; 2) the efficacy of both pixel-based and catalog-based corrections for the worsening WFC charge-transfer efficiency (CTE); 3) the extension of pixel-based CTE correction to the WFC 2K subarray mode; and 4) a novel "self-calibration" technique appropriate for large-number stacks of deep WFC exposures (such as the HFF targets) that provides superior reductions compared to the standard CALACS reduction pipeline.

    To maximize positive health outcomes for youth with HIV as they transition from youth to adult care, clinical staff need strategies and protocols to help youth maintain clinic engagement and medication adherence. Accordingly, this paper describe transition processes across twelve clinics within the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) to provide lessons learned and inform the development of transition protocols to improve health outcomes as youth shift from adolescent to adult HIV care. During a large multi-method Care Initiative program evaluation, three annual visits were completed at each site from 2010-2012 and conducted 174 semi-structured interviews with clinical and program staff (baseline n=64, year 1 n=56, year 2=54). The results underscore the value of adhering to recent American Academy of Pediatrics (AAP) transition recommendations, including: developing formal transition protocols, preparing youth for transition, facilitating youth's connection to the adult clinic, and identifying necessary strategies for transition evaluation. Transitioning youth with HIV involves targeting individual-, provider-, and system-level factors. Acknowledging and addressing key barriers is essential for developing streamlined, comprehensive, and context-specific transition protocols. Adolescent and adult clinic involvement in transition is essential to reduce service fragmentation, provide coordinated and continuous care, and support individual and community level health.

    The aim of the study was to correlate the clinical severity of pectus excavatum with its type and degree based on objective radiographic evaluation. Twelve brachycephalic dogs were included. Grading of the clinical severity was done based on a 6-point grading score. Thoracic radiographs were used to calculate the frontosagittal and vertebral indices at the tenth thoracic vertebra and the vertebra overlying the excavatum. Correlation between the clinical severity score and frontosagittal and vertebral indices was evaluated using Pearson's correlation coefficient. Typical pectus excavatum was recorded in the caudal sternum in seven dogs, with a mean clinical severity score of 1.7 ± 1.4, whereas in five dogs, atypical mid-sternal deviation was recorded with a mean clinical severity score of 3.8 ± 0.7. A strong correlation (r=0.7) was recorded between the clinical severity score and vertebral index in the atypical form, whereas a weak correlation (r=0.02) was recorded in the typical form (Pcorrelated (r=0.3) in the typical form of pectus excavatum, whereas it was strongly correlated (r=0.9) in the atypical form. Pectus excavatum in dogs is associated with compressive cardiopulmonary dysfunction, which depends mainly on the site/type of deviation rather than the degree of deviation.

    Suspended sediment and water samples collected from twelve major rivers in the Northwest Territories were analyzed for aliphatic hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) to assess the sources and transport of hydrocarbons entering the Arctic Ocean. Three stations on the Mackenzie River and one station near the mouth of eleven other northern rivers were selected for sampling. Samples were collected on the Mackenzie River on four occasions to characterize spring, summer and fall flow conditions and once on the remaining eleven rivers during high flow conditions. The Mackenzie River is distinctively different then the other eleven rivers. Naturally occurring hydrocarbons predominate in the river. These hydrocarbons include biogenic alkanes, diagenic PAHs, petrogenic alkanes, and PAHs from oil seeps and/or bitumens. Anthropogenic inputs of PAHs are low as indicated by low concentrations of combustion PAHs. Alkyl PAH distributions indicate that a significant component of the lower molecular weight PAH fraction is petrogenic. The majority of the high molecular weight PAHs, together with the petrogenic PAHs have a principal source in the Mackenzie River

    Full Text Available Thousands of whole-genome and whole-proteome sequences have been made available through advances in sequencing technology, and sequences of millions more organisms will become available in the coming years. This wealth of genetic information will provide numerous opportunities to enhance our understanding of these organisms including a greater understanding of relationships among species. Researchers have used 16S rRNA and other gene sequences to study the evolutionary origins of bacteria, but these strategies do not provide insight into the sharing of genes among bacteria via horizontal transfer. In this work we use an open source software program called pClust to cluster proteins from the complete proteomes of twelve species of Alphaproteobacteria and generate a dendrogram from the resulting orthologous protein clusters. We compare the results with dendrograms constructed using the 16S rRNA gene and multiple sequence alignment of seven housekeeping genes. Analysis of the whole proteomes of these pathogens grouped Rickettsia typhi with three other animal pathogens whereas conventional sequence analysis failed to group these pathogens together. We conclude that whole-proteome analysis can give insight into relationships among species beyond their phylogeny, perhaps reflecting the effects of horizontal gene transfer and potentially providing insight into the functions of shared genes by means of shared phenotypes.

    Full Text Available China has been experiencing severe air pollution and previous studies have mostly focused on megacities and a few hot spot regions. Hefei, the provincial capital city of Anhui province, has a population of near 5 million in its metropolitan area, but its air quality has not been reported in literature. In this study, daily PM10 and visibility data in 2001–2012 were analyzed to investigate the air quality status as well as the twelve-year pollution trends in Hefei. The results reveal that Hefei has been suffering high PM10 pollution and low visibility during the study period. The annual average PM10 concentrations are 2~3 times of the Chinese Ambient Air Quality Standard. PM10 shows fluctuating variation in 2001–2007 and has a slightly decreasing trend after 2008. The annual average visibility range is generally lower than 7 km and shows a worsening trend from 2001 to 2006 followed by an improving trend from 2007 to 2012. Wind speed, precipitation, and relative humidity have negative effects on PM10 concentrations in Hefei, while temperature could positively or negatively affect PM10. The results provide a general understanding of the status and long-term trends of PM10 pollution and visibility in a typical second-tier city in China.

    2002-01-01

    The p sup 4 He elastic scattering at the energy range from 0.695 to 393 GeV is analyzed in the framework of the Glauber theory. The Glauber amplitudes were evaluated using isospin-averaged nucleon-nucleon amplitudes and the sup 4 He wave function as a superposition of the Gaussian functions. The values of the calculated differential cross sections usually exceed the experimental ones. In order to overcome the discrepancy, it is assumed following to the paper by L. G. Dakno and N. N. Nikolaev that the ground state wave function of sup 4 He has an admixture of a twelve quark bag. Neglecting all transition amplitudes, the p - 12q bag scattering amplitude was chosen in a simple Gaussian form.The inclusion of the 12q bag leads to decreasing the p sup 4 He differential cross section and to a shift of the dip position to a large values of t what is needed for a successful description of the experimental data. While fitting the data it is found that the weight of the 12q bag state in the ground state of the sup 4 He ...

  4. What about Gender in Climate Change? Twelve Feminist Lessons from Development

    2018-02-01

    Full Text Available Adaptation and mitigation are two key responses to climate change. In the global South they prompt many questions: what is the direction and degree of change needed? How can new climate change policies be aligned with existing development initiatives? How are core social relations such as gender understood and prioritized in relation to technical and other solutions? In search of synergies between adaptation, development and mitigation, this article asks a pertinent question for sub-Saharan small-scale agriculture in particular: what can adaptation and mitigation learn from development debates on social goal setting, institutional change and gender equality? From the perspective of sustainability science and feminist literature, three main findings emerge. First, as regards social goal setting, adaptation and mitigation should, like development, support the escape out of poverty, ill-health and food-insecurity. Second, as regards institutions, adaptation and mitigation should address how gender regulates access to, use of and control over resources in terms of labor, land and strategic decision-making power. Third, as regards gender equality, adaptation and mitigation should learn from how development in theory and practice has addressed gender, women, nature and the environment. At its core, the analysis contributes twelve salient themes that can significantly inform adaptation and mitigation in research, policy and practice, thus serving as inspiration for a critical debate on much needed synergetic trajectories.

    The ecological conversion efficiencies in twelve species of fish in the Yellow Sea Ecosystem, i.e., anchovy ( Engraulis japonicus), rednose anchovy ( Thrissa kammalensis), chub mackerel ( Scomber japonicus), halfbeak ( Hyporhamphus sajori), gizzard shad ( Konosirus punctatus), sand lance ( Ammodytes personatus), red seabream ( Pagrus major), black porgy ( Acanthopagrus schlegeli), black rockfish ( Sebastes schlegeli), finespot goby ( Chaeturichthys stigmatias), tiger puffer ( Takifugu rubripes), and fat greenling ( Hexagrammos otakii), were estimated through experiments conducted either in situ or in a laboratory. The ecological conversion efficiencies were significantly different among these species. As indicated, the food conversion efficiencies and the energy conversion efficiencies varied from 12.9% to 42.1% and from 12.7% to 43.0%, respectively. Water temperature and ration level are the main factors influencing the ecological conversion efficiencies of marine fish. The higher conversion efficiency of a given species in a natural ecosystem is acquired only under the moderate environment conditions. A negative relationship between ecological conversion efficiency and trophic level among ten species was observed. Such a relationship indicates that the ecological efficiency in the upper trophic levels would increase after fishing down marine food web in the Yellow Sea ecosystem.

  6. Peer teaching in medical education: twelve reasons to move from theory to practice.

    2007-09-01

    To provide an estimation of how often peer teaching is applied in medical education, based on reports in the literature and to summarize reasons that support the use of this form of teaching. We surveyed the 2006 medical education literature and categorised reports of peer teaching according to educational distance between students teaching and students taught, group size, and level of formality of the teaching. Subsequently, we analysed the rationales for applying peer teaching. Most reports were published abstracts in either Medical Education's annual feature 'Really Good Stuff' or the AMEE's annual conference proceedings. We identified twelve distinct reasons to apply peer teaching, including 'alleviating faculty teaching burden', 'providing role models for junior students', 'enhancing intrinsic motivation' and 'preparing physicians for their future role as educators'. Peer teaching appears to be practiced often, but many peer teaching reports do not become full length journal articles. We conclude that specifically 'near-peer teaching' appears beneficial for student teachers and learners as well as for the organisation. The analogy of the 'journeyman', as intermediate between 'apprentice' and 'master', with both learning and teaching tasks, is a valuable but yet under-recognized source of education in the medical education continuum.

    In the course of achieving abstinence from alcohol, longstanding members of Alcoholics Anonymous (AA) typically experience a change in their addiction-related attitudes and behaviors. These changes are reflective of physiologically grounded mechanisms which can be investigated within the disciplines of social and cognitive neuroscience. This article is designed to examine recent findings associated with these disciplines that may shed light on the mechanisms underlying this change. Literature review and hypothesis development. Pertinent aspects of the neural impact of drugs of abuse are summarized. After this, research regarding specific brain sites, elucidated primarily by imaging techniques, is reviewed relative to the following: Mirroring and mentalizing are described in relation to experimentally modeled studies on empathy and mutuality, which may parallel the experiences of social interaction and influence on AA members. Integration and retrieval of memories acquired in a setting like AA are described, and are related to studies on storytelling, models of self-schema development, and value formation. A model for ascription to a Higher Power is presented. The phenomena associated with AA reflect greater complexity than the empirical studies on which this article is based, and certainly require further elucidation. Despite this substantial limitation in currently available findings, there is heuristic value in considering the relationship between the brain-based and clinical phenomena described here. There are opportunities for the study of neuroscientific correlates of Twelve-Step-based recovery, and these can potentially enhance our understanding of related clinical phenomena. © American Academy of Addiction Psychiatry.

    The objective of this study was to establish the pharmacokinetic parameters of ceftiofur crystalline free acid (CCFA) for a single intramuscular injection in green iguanas ( Iguana iguana). Six green iguanas received an injection of 5 mg/kg CCFA into the triceps muscle. Using high-performance liquid chromatography, concentrations of ceftiofur free acid equivalents in plasma samples collected at predetermined time points were evaluated up to 21 days following drug administration. Noncompartmental pharmacokinetic analysis was applied to the data. The observed maximum plasma concentration (C max obs ) was 2.765 ± 0.864 μg/mL, and the time of observed maximum concentration (T max obs ) was 6.1 ± 9.2 hr. The area under the curve (0 to infinity) was 239.3 ± 121.1 μg·hr/mL. No significant adverse drug reactions were clinically observed, and no visible injection site reactions were noted. Minimum inhibitory concentrations of bacterial isolates from iguanas were used to establish a target plasma concentration of 2.0 μg/mL. Based on the results from this study, a potential dosing interval for ceftiofur crystalline free acid administered at 5 mg/kg intramuscularly for iguanas maintained at a temperature of 30°C would be 24 hr based on a target plasma concentration of 2 μg/mL; however, multidose studies still need to be performed.

    To evaluate Korean physiatrists' practice of performing intramuscular botulinum toxin injection in anticoagulated patients and to assess their preference in controlling the bleeding risk before injection. As part of an international collaboration survey study, a questionnaire survey was administered to 100 Korean physiatrists. Physiatrists were asked about their level of experience with botulinum toxin injection, the safe international normalized ratio range in anticoagulated patients undergoing injection, their tendency for injecting into deep muscles, and their experience of bleeding complications. International normalized ratio injection by 41% of the respondents. Thirty-six respondents replied that the international normalized ratio should be lowered to sub-therapeutic levels before injection, and 18% of the respondents reported that anticoagulants should be intentionally withheld and discontinued prior to injection. In addition, 20%-30% of the respondents answered that they were uncertain whether they should perform the injection regardless of the international normalized ratio values. About 69% of the respondents replied that they did have any standardized protocols for performing botulinum toxin injection in patients using anticoagulants. Only 1 physiatrist replied that he had encountered a case of compartment syndrome. In accordance with the lack of consensus in performing intramuscular botulinum toxin injection in anticoagulated patients, our survey shows a wide range of practices among many Korean physiatrists; they tend to avoid botulinum toxin injection in anticoagulated patients and are uncertain about how to approach these patients. The results of this study emphasize the need for formulating a proper international consensus on botulinum toxin injection management in anticoagulated patients.

    The lethal toxicity values (log 1/LD(50)) of 527 aliphatic and aromatic compounds in oral, intravenous, intramuscular and intraperitoneal routes were used to investigate the relationships of log 1/LD(50) from different exposure routes. Regression analysis shows that the log 1/LD(50) values are well correlated between intravenous and intraperitoneal or intramuscular injections. However, the correlations between oral and intravenous or intraperitoneal routes are relatively poor. Comparison of the average residuals indicates that intravenous injection is the most sensitive exposure route and oral administration is the least sensitive exposure route. This is attributed to the difference in kinetic process of toxicity testing. The toxic effect of a chemical can be similar or significantly different between exposure routes, depending on the absorption rates of chemicals into blood. Inclusion of hydrophobic parameter and fractions of ionic forms can improve the correlations between intravenous and intraperitoneal or oral routes, but not between intraperitoneal and oral routes. This is due to the differences of absorption rate in different exposure environments from different routes. Several factors, such as experimental uncertainty, metabolism and toxic kinetics, can affect the correlations between intravenous and intraperitoneal or oral routes. Copyright © 2015 Elsevier Inc.

    The designer antibacterial peptide A3-APO is efficacious in mouse models of Escherichia coli and Acinetobacter baumannii systemic infections. Here we compare the efficacy of the peptide with that of imipenem and colistin in A. baumannii wound infections after burn injury. CD-1 mice were inflicted with burn wounds and different inocula of A. baumannii, isolated from an injured soldier, were placed into the wound sites. The antibiotics were given intramuscularly (im) one to five times. Available free peptide in the blood and the systemic toxicity of colistin and A3-APO were studied in healthy mice. While toxicity of colistin was observed at 25 mg/kg bolus drug administration, the lowest toxic dose of A3-APO was 75 mg/kg. In the A. baumannii blast injury models, 5 mg/kg A3-APO improved survival and reduced bacterial counts in the blood as well as in the wounds and improved wound appearance significantly better than any other antibiotic treatment. The free peptide concentration in the blood did not reach 1 µg/mL. Peptide A3-APO, with an intramuscular therapeutic index of 15, is more efficacious and less toxic than any existing burn injury infection therapy modality against multidrug-resistant Gram-negative pathogens. A3-APO administered by the im route probably binds to a biopolymer that promotes the peptide's biodistribution.

    Full Text Available Background. While behavioral and psychological symptoms are frequent in hospitalized older adults with dementia or delirium, data supporting the off-label use of intramuscular atypical antipsychotics remain scarce. We examined the use of short-acting intramuscular (IM olanzapine in hospitalized older adults to manage behavioral and psychological symptoms. Methods. A retrospective observational study of inpatients 65 years or older with at least one order for olanzapine IM during admission in urban Ontario Canada was conducted. Patient demographics, prescriptions for olanzapine IM, reason for administration, perceived effectiveness, adverse events, concurrently prescribed psychotropics, comorbidities, and patient discharge destination were recorded. Results. Among 82 patients aged 65–96 years (mean ± SD 79.3 ± 7.7 85 cases were identified. Cognitive impairment or dementia affected 63.5% and 50.6% had comorbidities. Olanzapine IM was ordered 102 times and 34 patients (41% received at least one dose. The intended efficacy was achieved in 79.4% of 78 cases of 124 doses given (62.9%. Fourteen (41% patients who received doses experienced adverse events, with sedation and hypotension being the most common. Conclusions. Olanzapine IM appears effective in hospitalized older adults but is associated with potential adverse events. Structured monitoring and documentation are needed to ensure safe use in this high-risk population.

    1983-01-01

    A single oral (10 mg/kg of body weight) or IM (7.5 mg/kg) dose of [ 3 H]levamisole was administered to pigs. Liquid scintillation counting and high performance liquid chromatography were used to determine total radioactivity and drug levels in plasma, duodenal and cecal contents, bile, and urine for 24 and 72 hours after dosing. Pharmacokinetic analysis indicated a 1-compartment open model with higher plasma bioavailability of levamisole after IM injection. Biological half-lives for elimination of the drug were 9.3 and 6.9 hours after oral and IM administration, respectively. Anthelmintic concentrations were higher in intestinal contents after oral gavage than after IM injection. The drug appeared extensively metabolized in all body fluids and particularly in bile, regardless of the route of administration. Biliary excretion of radioactivity and unchanged levamisole represented only slight percentages of the administered dose (approx 0.4% and 4.2%, respectively, in 72 hours). In contrast, about 60% and 20% of the dose were eliminated via urine as tritiated materials and unchanged drug. The choice of the most efficacious route of administration is discussed in regard to localization of helminthic disease

    Both short- and long-acting formulations of oxytetracycline are commonly used in veterinary medicine to treat animals infected with gram-negative and gram-positive bacteria, rickettsiae, mycoplasma, and chlamydiae. To compare pharmacokinetics of short- and long-acting oxytetracycline in chickens, injectable formulations from the same pharmaceutical company were administered to healthy 6-week-old broiler chickens in accordance to the labeled instructions. Fourteen chickens were separated into 2 groups: chickens in group A (n = 7) were administered the short-acting formulation (10 mg/kg IM q24h) for 4 consecutive days, whereas those in group B (n = 7) were treated with a single dose (20 mg/kg IM) of the long-acting formulation. Blood samples were collected into heparinized tubes before and at 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 10, and 24 hours after initial treatment. Thereafter, blood samples were taken every 24 hours up to 120 hours. Plasma concentrations of oxytetracycline were determined by competitive enzyme-linked immunoabsorbent assay, and pharmacokinetic parameters were obtained. Both formulations delivered therapeutic plasma concentrations of oxytetracycline for approximately 100% of their respective dosing intervals as recommended. However, considering the additional labor, patient stress, and mortalities associated with handling, in addition to rejection of the carcass due to tissue necrosis resulting from multiple injections, we recommend use of the long-acting instead of the short-acting injectable formulation in broiler chickens.

  17. Comparison between the Effects of Oral and Intramuscular Administration of Shin’iseihaito (Xinyiqingfeitang in a Streptococcus pyogenes-Induced Murine Sinusitis Model

    Full Text Available Streptococcus pyogenes (S. pyogenes is a species of Gram-positive coccoid bacteria having many virulence factors. Its capsule and exotoxins can cause upper respiratory tract infections such as sinusitis. The general treatment for S. pyogenes-induced sinusitis is administration of antibiotics such as penicillin and macrolides; however, a serious problem associated with these antibiotics is their attenuated effect. Shin’iseihaito (Xinyiqingfeitang, a formula of Japanese traditional Kampo medicine and traditional Chinese medicine, has been used for the treatment of sinusitis. In general, formulas of Japanese traditional Kampo medicine are orally administered. This is in contrast to certain formulas of traditional Chinese medicine, which are being recently administered intramuscularly or intravenously. Regarding these traditional Chinese medicine formulas, the injection methodology is reported to be more effective than oral intake. In this study, we compared the efficacy between orally and intramuscularly administered Shin’iseihaito against S. pyogenes-induced sinusitis. We evaluated the antibacterial effect of Shin’iseihaito extract (SSHT against S. pyogenes by K-B disk diffusion assay. Furthermore, we investigated the nasal colonization of S. pyogenes, determined cytokine (TNF-α, IL-1β, and IL-6 levels, and conducted a splenocyte proliferative assay in a murine sinusitis model. SSHT displayed direct anti-S. pyogenes activity. Intramuscular administration of SSHT decreased the nasal colonization of S. pyogenes compared with oral administration. Thymidine uptake analysis revealed that the proliferation of splenocytes from S. pyogenes-infected mice under intramuscular SSHT treatment was upregulated compared to that of splenocytes from S. pyogenes-infected mice under oral SSHT treatment. We also found that TNF-α, IL-1β, and IL-6 levels in the nasal discharge from intramuscularly treated S. pyogenes-infected mice were lower than those from

    Full Text Available Current artesunate (ARS regimens for severe malaria are complex. Once daily intramuscular (i.m. injection for 3 d would be simpler and more appropriate for remote health facilities than the current WHO-recommended regimen of five intravenous (i.v. or i.m. injections over 4 d. We compared both a three-dose i.m. and a three-dose i.v. parenteral ARS regimen with the standard five-dose regimen using a non-inferiority design (with non-inferiority margins of 10%.This randomized controlled trial included children (0.5-10 y with severe malaria at seven sites in five African countries to assess whether the efficacy of simplified three-dose regimens is non-inferior to a five-dose regimen. We randomly allocated 1,047 children to receive a total dose of 12 mg/kg ARS as either a control regimen of five i.m. injections of 2.4 mg/kg (at 0, 12, 24, 48, and 72 h (n = 348 or three injections of 4 mg/kg (at 0, 24, and 48 h either i.m.

The primary endpoint was the proportion of children with ≥ 99% reduction in parasitemia at 24 h from admission values, measured by microscopists who were blinded to the group allocations. Primary analysis was performed on the per-protocol population, which was 96% of the intention-to-treat population. Secondary analyses included an analysis of host and parasite genotypes as risks for prolongation of parasite clearance kinetics, measured every 6 h, and a Kaplan-Meier analysis to compare parasite clearance kinetics between treatment groups. A post hoc analysis was performed for delayed anemia, defined as hemoglobin ≤ 7 g/dl 7 d or more after admission. The per-protocol population was 1,002 children (five-dose i.m.: n = 331; three-dose i.m.: n = 338; three-dose i.v.: n = 333; 139 participants were lost to follow-up. In the three-dose i.m. arm, 265/338 (78% children had a ≥ 99% reduction in parasitemia at 24 h compared to 263/331 (79% receiving the five-dose i

    Full Text Available A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte during 1996 in order to assess the weight of preterm appropriate-for-gestational-age newborns during the first twelve weeks of life. Two hundred and sixty appropriate-for-gestational-age preterm infants with birth weight <2500 g were evaluated weekly. The infants were divided into groups based on birth weight at 250-g intervals. Using weight means, somatic growth curves were constructed and adjusted to Count's model. Absolute (g/day and relative (g kg-1 day-1 velocity curves were obtained from a derivative of this model. The growth curve was characterized by weight loss during the 1st week (4-6 days ranging from 5.9 to 13.3% (the greater the percentage, the lower the birth weight, recovery of birth weight within 17 and 21 days, and increasingly higher rates of weight gain after the 3rd week. These rates were proportional to birth weight when expressed as g/day (the lowest and the highest birth weight neonates gained 15.9 and 30.1 g/day, respectively. However, if expressed as g kg-1 day-1, the rates were inversely proportional to birth weight (during the 3rd week, the lowest and the highest weight newborns gained 18.0 and 11.5 g kg-1 day-1, respectively. During the 12th week the rates were similar for all groups (7.5 to 10.2 g kg-1 day-1. The relative velocity accurately reflects weight gain of preterm infants who are appropriate for gestational age and, in the present study, it was inversely proportional to birth weight, with a peak during the 3rd week of life, and a homogeneous behavior during the 12th week for all weight groups.

    During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has supported a wide range of Education and Public Outreach (E/PO) activities, targeting K-14 students and the general public. The purpose of the Fermi E/PO program is to increase student and public understanding of the science of the high-energy Universe, through inspiring, engaging and educational activities linked to the mission’s science objectives. The E/PO program has additional more general goals, including increasing the diversity of students in the Science, Technology, Engineering and Mathematics (STEM) pipeline, and increasing public awareness and understanding of Fermi science and technology. Fermi's multi-faceted E/PO program includes elements in each major outcome category: ● Higher Education: Fermi E/PO promotes STEM careers through the use of NASA data including research experiences for students and teachers (Global Telescope Network), education through STEM curriculum development projects (Cosmology curriculum) and through enrichment activities (Large Area Telescope simulator). ● Elementary and Secondary education: Fermi E/PO links the science objectives of the Fermi mission to well-tested, customer-focused and NASA-approved standards-aligned classroom materials (Black Hole Resources, Active Galaxy Education Unit and Pop-up book, TOPS guides, Supernova Education Unit). These materials have been distributed through (Educator Ambassador and on-line) teacher training workshops and through programs involving under-represented students (after-school clubs and Astro 4 Girls). ● Informal education and public outreach: Fermi E/PO engages the public in sharing the experience of exploration and discovery through high-leverage multi-media experiences (Black Holes planetarium and PBS NOVA shows), through popular websites (Gamma-ray Burst Skymap, Epo's Chronicles), social media (Facebook, MySpace), interactive web-based activities (Space Mysteries, Einstein@Home) and activities by
