    We experienced a case of the complications following glycerin enema which suggested malignant hyperthermia. A 73-year-old man with knee osteoarthritis was scheduled for total knee arthroplasty under general and epidural anesthesia. The patient received glycerin enema before surgery. After epidural catheterization, anesthesia was induced with thiopental, fentanyl, vecuronium and sevoflurane. The trachea was intubated and the patient was ventilated with sevoflurane-air-oxygen. Then, cola-like urine was drained and he became febrile up to 37.9 degrees C. Although there were no other symptoms suggesting malignant hyperthermia, the surgery was cancelled. We suspected not only hemolysis by the color of the serum and the blood chemistry, but also rhabdomyolysis by increased levels of serum creatine phosphokinase and myoglobin as well as urine myoglobin. He recovered uneventfully. On the third day, perirectal abscess and anal fissure were diagnosed, which were considered to be the cause of the fever. It is well-known that glycerin enema could cause hemolysis, but rabdomyolysis as a complication of glycerin enema has rarely been reported. We speculate that injection of hypertonic glycerin into the perirectal tissue could have caused rhabdomyolysis as well as hemolysis, which led to cola-like urine. The complications following glycerin enema can be incorporated to a differential diagnosis of malignant hyperthermia.

    Premature infants are often given glycerin enemas or suppositories to facilitate meconium evacuation and transition to enteral feeding. The purpose of this study was to assess the available evidence for this treatment strategy. We conducted a systematic search of Medline, Embase, Central, and trial registries for randomized controlled trials of premature infants treated with glycerin enemas or suppositories. Data were extracted in duplicate and meta-analyzed using a random effects model. We identified 185 premature infants treated prophylactically with glycerin enemas in one trial (n = 81) and suppositories in two other trials (n = 104). All infants were less than 32 weeks gestation and had no congenital malformations. Treatment was associated with earlier initiation of stooling in one trial (2 vs 4 days, P = .02) and a trend towards earlier meconium evacuation in another (6.5 vs 9 days, P = .11). Meta-analysis demonstrated no effect on transition to enteral feeding (0.7 days faster, P = .43) or mortality (P = 0.50). There were no reports of rectal bleeding or perforation but there was a trend towards increased risk of necrotizing enterocolitis with glycerin enemas or suppositories (risk ratio = 2.72, P = .13). These three trials are underpowered and affected by one or more major methodological issues. As a result, the quality of evidence is low to very low. Three other trials are underway. The evidence for the use glycerin enemas or suppositories in premature infants in inconclusive. Meta-analyzed data suggest that treatment may be associated with increased risk of necrotizing enterocolitis. Careful monitoring of ongoing trials is required.

    A 94-year-old female patient with femoral neck fracture received 60 ml glycerin enema prior to surgery, according to the preoperative preparation protocol. She was found unconscious and unresponsive 60 minutes after the treatment. Vital signs were checked and ECG monitoring was started. The results were unremarkable and similar to those recorded at the time of admission. A neurologist was consulted, and a thorough evaluation was performed. None of physical and neurological examination, laboratory testing and urgent intracranial imaging revealed significant abnormalities or lesion responsible for the depressed consciousness. Vasovagal reflex triggered by enema and the consequent hypotension was thought to be the most likely cause of transient cerebral hypoperfusion resulting in loss of consciousness. The patient remained unresponsive for the next 2 hours, and came to open her eyes with tapping stimuli. She took another hour to fully regain consciousness without any residual neurologic deficit. Her surgery was cancelled. Vasovagal reflex is known to be one of the potential complications associated with enema. Our experience suggests that the necessity of glycerin enema for preoperative bowel preparation in elderly patients should be cautiously determined and it should be given, if necessary, under adequate vigilance.

    This study compared the efficacy and patient acceptability of two methods of bowel preparation for flexible sigmoidoscopy. Patients attending for outpatient flexible sigmoidoscopy were prospectively randomized to receive one Fleet ready-to-use enema or 2 x 4 g glycerin suppositories, 2 h preprocedure. Patient and endoscopist questionnaires were used to compare the outcomes. From November 2000 to August 2001, 203 (male = 95; female = 108) patients were randomized. Patient data available for 163 patients (enema = 93; suppository = 70) revealed: ease of use (enema = 52; suppository = 25; P suppository = 3; P suppository = 44; P suppository = 24; P = 0.016, Fisher's exact). Endoscopist data available for 151 patients (enema = 76; suppository = 75) revealed: average depth of insertion (enema = 53.6 +/- 11.6 cm; suppository 46.3 +/- 13.7 cm; P suppository = 34 (45.3%); P suppositories.

    Rectal perforations due to glycerin enemas (GE) typically occur when the patient is in a seated or lordotic standing position. Once the perforation occurs and peritonitis results, death is usually inevitable. We describe two cases of rectal perforation and fistula caused by a GE. An 88-year-old woman presented with a large rectal perforation and a fistula just after receiving a GE. Her case was further complicated by an abscess in the right rectal wall. The second patient was a 78-year-old woman who suffered from a rectovesical fistula after a GE. In both cases, we performed direct endoscopic abscess lavage with a saline solution and closed the fistula using an over-the-scope-clip (OTSC) procedure. These procedures resulted in dramatic improvement in both patients. Direct endoscopic lavage and OTSC closure are very useful for pararectal abscess lavage and fistula closure, respectively, in elderly patients who are in poor general condition. Our two cases are the first reports of the successful endoscopic closure of fistulae using double OTSCs after endoscopic lavage of the debris and an abscess of the rectum secondary to a GE.

    Full Text Available Abstract Background Enemas are used during labour in obstetric settings with the belief that they reduce puerperal and neonatal infections, shorten labour duration, and make delivery cleaner for attending personnel. However, a systematic review of the literature found insufficient evidence to support the use of enemas. The objective of this RCT was to address an identified knowledge gap by determining the effect of routine enemas used during the first stage of labour on puerperal and neonatal infection rates. Methods Design: RCT (randomised controlled trial; randomized clinical trial. Outcomes: Clinical diagnosis of maternal or neonatal infections, labour duration, delivery types, episiotomy rates, and prescription of antibiotics Setting: Tertiary care referral hospital at the Javeriana University (Bogotá, Colombia that attended 3170 births during study period with a caesarean section rate of 26%. Participants: 443 women admitted for delivery to the obstetrics service (February 1997 to February 1998 and followed for a month after delivery. Inclusion criteria were women with: low risk pregnancy and expected to remain in Bogotá during follow up; gestational age ≥ 36 weeks; no pelvic or systemic bacterial infection; intact membranes; cervix dilatation ≤7 cm. Intervention: 1 litre saline enema, versus no enema, allocated following a block random allocation sequence and using sealed opaque envelopes. Results Allocation provided balanced groups and 86% of the participants were followed up for one month. The overall infection rate for newborns was 21%, and 18% for women. We found no significant differences in puerperal or neonatal infection rates (Puerperal infection: 41/190 [22%] with enema v 26/182 [14%] without enema; RR 0.66 CI 95%: 0.43 to 1.03; neonatal infection 38/191 [20%] with enema v 40/179 [22%] without enema; RR 1.12, 95% CI 95% 0.76 to 1.66, and median labour time was similar between groups (515 min. with enema v 585 min. without

    Current summaries of effective maintenance dose ranges for subcutaneous immunotherapy (SCIT) are based on administration of 0.5-mL volumes. Extract formulations delivering equivalent dose ranges for practices using different injection volumes have not been reported, and calculation of the final glycerin concentrations in these solutions remains an inconvenient and repetitive process. To create math-free guides for allergen doses and glycerin concentrations that identify the extract concentrate volumes required to deliver doses within the ranges cited in the 2011 immunotherapy practice parameters for clinicians using 5.0-mL maintenance vials and injection volumes ranging from 0.2 to 1.0 mL. Algebraic calculations were performed to determine the specific combinations of extract concentrate strengths, volumes of these products in patient vaccines, and injection volumes needed for administration of target allergen doses spanning the current SCIT practice parameter recommendations. For each product or group (nonstandardized extracts), tables were constructed to define the allergen doses provided by various combinations of extract concentrate volumes and injection volumes. The values within the effective dose ranges for each product were highlighted to facilitate comparisons of specific conditions relevant to allergy specialists. Glycerin tables were also created to permit convenient assessments of the final concentrations of this stabilizer in patient prescriptions. SCIT dosing and glycerin tables are useful tools to assist allergists with practice decisions that involve variable patient formulas and injection volumes and can help identify suitable conditions for treatment of patients presenting with diverse allergen sensitivities and specificity profiles.

    The misuse of sodium phosphates enemas has resulted in reports of potentially severe metabolic and hemodynamic disturbances. Despite their long availability, these products have not been fully characterized pharmacokinetically. This trial sought to evaluate changes in the metabolic and hemodynamic parameters following the administration of one of two standard sodium phosphates enemas. Enema Casen (250 ml) is available only in Spain, and Fleet Enema (133 ml) is available in 66 countries in six continents of the world. These changes were correlated with scientific literature reports of hyperphosphatemia following phosphate enema use. Forty-five adult participants aged 50 years or older enrolled in the trial. Twenty-five participants were given one Enema Casen, whereas 20 participants received one Fleet Enema. Blood pressure, pulse, and serum chemistries were evaluated at screening; baseline; and 10, 60, and 120 minutes after receiving the enema. Each participant had a bowel movement within 10 minutes of receiving his enema. Asymptomatic, transient hyperphosphatemia was associated with increase in retention time but not with increase in volume of sodium phosphates enemas. Increased serum phosphate concentration and increased area under the curve of serum phosphate were associated with increased enema retention time. The Enema Casen induced a greater mean AUC of serum sodium concentration than did the Fleet Enema. There were no drug-related adverse events. Transient hyperphosphatemia following the use of sodium phosphates enemas correlates with retention time but not with dose. A scientific literature review of serious adverse events revealed that overdose, concomitant use of oral and rectal sodium phosphates products, and use in a contraindicated patient were associated with sodium phosphates enema and hyperphosphatemia.

    Rectal enemas that contain prophylactic levels of anti-HIV microbicides such as tenofovir have emerged as a promising dosage form to prevent sexually transmitted HIV infections. The enema vehicle is promising due to its likely ability to deliver a large amount of drug along the length of the rectal canal. Computational models of microbicide drug delivery by enemas can help their design process by determining key factors governing drug transport and, more specifically, the time history and degree of protection. They can also inform interpretations of experimental pharmacokinetic measures such as drug concentrations in biopsies. The present work begins rectal microbicide PK modeling, for enema vehicles. Results here show that a paramount factor in drug transport is the time of enema retention; direct connectivity between enema fluid and the fluid within rectal crypts is also important. Computations of the percentage of stromal volume protected by a single enema dose indicate that even with only a minute of enema retention, protection of 100% can be achieved after around 14 minutes post dose. Concentrations in biopsies are dependent on biopsy thickness; and control and/or knowledge of thickness could improve accuracy and decrease variability in biopsy measurements. Results here provide evidence that enemas are a promising dosage form for rectal microbicide delivery, and offer insights into their rational design. PMID:28114388

    The present study investigated the feasibility of a mono fermentation of the glycerine-fraction from biodiesel production. Part of the experiments took place in a single-stage, continuous system with 700 l usable volume. The maximum yield of biogas of the glycerine-fraction is 1100 l/l of glycerine, or 870 l/kg of glycerine, in continuous operation. The average methane content is 70 %. The adaptation rate of the biomass at the substrate of glycerine-fraction is high. Two or three days after starting the feed 100 % degradation rates will be achieved. The single-stage, continuous fermentation of the glycerine-fraction at 40 {sup o}C runs only stable at very low organic loading rate (0.65 kg oDM/(d m{sup 3})) and is therefore not currently economical. At higher organic loading rates (1.5 to 3.0 kg oDM/(d m{sup 3})) the adapted biomass collapsed after about 20 days due to massive instability of the process. A two-stage system with separate hydrolysis stage could probably allow a stable fermentation as search for literature has shown. Fed-batch experiments in the laboratory of the University of Waedenswil, Switzerland (ZHAW) demonstrated that the glycerine-fraction from biodiesel production is slightly better degradable than pure glycerine. The process dysfunctions arise because of the inhibition of intermediates resulting from the degradation of glycerine. At higher concentrations of 1.2-propanediol and 2.3-butanediol the degradation was incomplete. Further inhibitors can not be excluded. The failed stability of the process is not due to the lack of main nutrients or trace elements. (author)

  10. Retrograde spreading of hydrocortisone enema in inflammatory bowel disease

    A hydrocortisone suspension enema was radiolabeled with (/sup 99m/Tc)technetium sulfur colloid and administered to four normal subjects and eight patients with varying degrees of inflammatory bowel disease. The extent of enema spreading was monitored using external scintigraphy for a period of up to 4 hr after administration. Pretreatment of normal subjects with an evacuation enema resulted in spreading of the radiolabeled enema throughout the entire colon. In seven of the eight patients studied, the enema migrated a distance equal to or greater than the extent of disease involvement. An in vivo stability study with an indium-111-labeled enema, using the perturbed angular correlation technique, revealed that the enema retains its stability for up to 90 min after administration. These results indicate that the use of hydrocortisone enemas may not be restricted to distal bowel disease, but may also be effective in inflammatory bowel diseases involving proximal regions of the colon.

    Dássia Daiane Oliveira

    2014-02-01

    Full Text Available Two experiments evaluated the pure glycerin in broiler chicken diets. Experiment 1 was a metabolism test using total feces sampling method with 96 male chickens aging from 17 to 25 d when animals were fed on two treatments: diet1 = no glycerin and diet2 = 60g/kg of glycerin. The apparent metabolized energy measured 4015 kcal/kg and the apparent metabolized corrected for nitrogen balance was 3911 kcal/kg. Experiment 2 evaluated weight gains, feed intake and feed conversion in 480 chicks at 6, 20 and 34 d old fed on diets with 0, 40, 80 and 120 g/kg of glycerin. The results indicate that pure glycerin in chicken diets, as a source of energy must take into consideration the age of the animals and it may be added up to 120 g/kg, from 20 to 41 d of age.

    Objective: To evaluate the pituitary-adrenal axis (PA axis) reserve in patients with ulcerative colitis (UC) treated with steroid enemas, we performed 1mug ACTH test.Methods: Patients with UC (n=8) given beclomethasone dipropionate enema (Betnesol) for 4 weeks. Fasting serum cortisol and the response at 30 and 60 minutes following an IV 1mug ACTH injection were determined after 2 weeks of Betnesol enemas. Patients were retested, one month after discontinuation of enemas.Results: Fasting and peak cortisol responses to ACTH were suppressed in six patients. Additional patient had suppressed fasting cortisol and another patient had blunted response to ACTH. One month off Betnesol enema, basal and peak cortisol response to ACTH were normal in all but one patient.Conclusion: Betnesol enemas are associated with severe suppression of the PA axis in almost all patients. Caution is required in patients with UC after withdrawal of rectal steroids as adrenal insufficiency can occur.

    Three energy balance experiments were conducted to determine AMEn of glycerin using broiler chickens of diverse ages. In experiment 1, two dietary treatments were fed from 4 to 11 d of age. Dietary treatments consisted of a control diet (no added glycerin) and a diet containing 6% glycerin (94% control diet + 6% glycerin). Four dietary treatments were provided in experiment 2 (from 17 to 24 d of age) and 3 (from 38 to 45 d of age). Diets in experiment 2 and 3 were 1) control diet (no added glycerin); 2) 3% added glycerin (97% control diet + 3% glycerin); 3) 6% added glycerin (94% control diet + 6% glycerin); and 4) 9% added glycerin (91% control diet + 9% glycerin). Diets in experiment 1 and 2 were identical, but the diet used in experiment 3 had reduced nutrient levels based on bird age. In experiments 2 and 3, broilers were fed 91, 94, 97, and 100% of ad libitum intake so that differences in AMEn consumption were only due to glycerin. A single source of glycerin was used in all experiments. Feed intake, BW, energy intake, energy excretion, nitrogen intake, nitrogen excretion, AMEn, and AMEn intake were determined in all experiments. In experiment 1, AMEn determination utilized the difference approach by subtracting AMEn of the control diet from AMEn of the test diet. In experiments 2 and 3, AMEn intake was regressed against feed intake with the slope estimating AMEn of glycerin. Regression equations were Y = 3,331x -72.59 (P glycerin was determined as 3,621, 3,331, and 3,349 kcal/kg in experiments 1, 2, and 3, respectively. The average AMEn of glycerin across the 3 experiments was 3,434 kcal/kg, which is similar to its gross energy content. These results indicate that AMEn of glycerin is utilized efficiently by broiler chickens.

    Initial management of intussusception is enema reduction. Data are scarce on predicting which patients are unlikely to have a successful reduction. Therefore, we reviewed our experience to identify factors predictive of enema failure. A retrospective review of all episodes of intussusception over the past 10 years was conducted. Demographics, presentation variables, colonic extent of intussusceptions, and hospital course were collected. Extent of intussusception was classified as right, transverse, descending, and rectosigmoid. Episodes were grouped as success or failure of enema reduction and compared using the Student t test for continuous variables and χ(2) test for dichotomous variables. Significance was P less than .05. We identified 405 episodes of intussusception and 371 attempts at enema reduction. There were 285 successful enema reductions. There was no difference between groups in age; sex; or the presence of emesis, fever, or abdominal mass. The failed enema group was more likely to have had symptoms over 24 hours before presentation (P = .006), bloody diarrhea (P Predictors of failed enema reduction of intussusception include presence of symptoms over 24 hours, diarrhea, lethargy, and distal extent of intussusception.

    Phosphate enemas are frequently used in the treatment of constipation. Errors in dosage and administration can lead to severe complications. To report a case of severe toxicity of phosphate enemas in a child with no risk factors. 2 years old female, with functional constipation, was brought to emergency department because abdominal pain. She was diagnosed with fecal impaction and received half a bottle of Fleet Adult® (Laboratorio Synthon, Chile) two times, with no clinical resolution, deciding to start proctoclisis in pediatric ward. Soon after admission, she presented painful tetany, but alert and oriented. Patient was transferred to PICU where severe hyperphosphatemia and secondary hypocalcemia were confirmed. Her treatment included electrolyte correction; removal of residual phosphate enema and hyperhydration. Tetany resolved over 2 hours after admission and no other complications. Proctoclisis was performed and patient was discharged three days after admission with pharmacological management of constipation. Phosphate enemas may cause serious complications in children with no risk factors. Errors in dosage, administration and removal of the enema are causes of toxicity in this group. Pediatricians and health personnel must be aware of risks and signs of toxicity of phosphate enema.

    A double blind multicentre study comparing sodium cromoglycate (600 mg/100 ml) by enema with prednisolone (20 mg/100 ml) by enema is reported. The study was conducted over a nine week period in the treatment of 70 patients with ulcerative colitis. Analysis of symptoms showed significant decreases in scores for patients in both groups, both at four and eight weeks; the only difference between the two groups was a significantly greater improvement in the reduction of rectal bleeding after four weeks in the prednisolone group. On sigmoidoscopy, both treatment groups showed a highly significant improvement after four and eight weeks with no significant differences being seen between the groups. Histology of the rectal biopsies showed a significant improvement in the inflammation of the mucosa for both treatment groups after four and eight weeks with no differences being observed between the groups. There were no significant changes in eosinophils from baseline and no difference between the groups at four and eight weeks. PMID:3102323

    2005-10-01

    Glycerin is applied to cigarette tobacco at levels in the range of about 1-5% to improve moisture holding characteristics of tobacco and act as a surface active agent for flavor application. Neat material pyrolysis studies, smoke chemistry and biological activity studies (bacterial mutagenicity, cytotoxicity, in vivo micronucleus, and sub-chronic rodent inhalation) with mainstream smoke, or mainstream smoke preparations from cigarettes containing various target levels (5%, 10%, and 15%) of the glycerin were performed to provide data for an assessment of the use of glycerin as a cigarette tobacco ingredient. The actual levels of glycerin in the respective test cigarettes were determined to be 3.2%, 6.2% and 8.4% after cigarette production. At simulated tobacco burning temperatures up to 900 degrees C, neat glycerin did not pyrolyze extensively suggesting that glycerin would transfer intact to mainstream smoke (smoke was not analyzed for glycerin in this study). On a tar basis, nicotine in smoke was significantly decreased at 10% and 15% glycerin while water was increased at all addition levels. Addition of 10% or 15% glycerin also resulted in a statistically significant increase in acrolein (9%) and a decrease in acetaldehyde, propionaldehyde, aromatic amines, nitrogen oxides, tobacco specific nitrosamines, and phenols. Addition of 5% glycerin produced the same decrease in smoke constituents as the 10% and 15% groups but there was no concomitant increase in acrolein. Biological tests indicated no relevant differences in the genotoxic or cytotoxic potential of either mainstream smoke (or smoke preparations) from cigarettes with added glycerin compared to control cigarettes. Cigarette smoke atmosphere dilution, coupled with the lower nicotine delivery in the test cigarettes containing glycerin resulted in a lower nicotine delivery to the glycerin cigarette smoke exposed rats of the 90-day inhalation study. Smoke atmosphere acrolein was also reduced in a concentration

    1983-12-01

    The results of 1,500 barium enema studies done by vigorous manual palpation under fluoroscopy were reviewed to determine the adequacy of this technique in detecting polyps above the proctoscopic level. Of the 1,500 patients examined, 103 (7%) were diagnosed radiographically as having a total of 149 polyps. Polyps were found at proctoscopy in about 10% of the 1,500 patients. Colonoscopy or surgery was performed on 35 of the 103 patients. Of the 52 polyps discovered during these procedures, only three were missed at fluoroscopic barium enema study, a false-negative rate of 6%. Fourteen patients whose barium enemas initially were reported as negative for polyps or neoplasia had colonoscopy. Two of the 14 patients had positive findings, for a true-negative rate of 86%. If the detection rate of 7% found at barium enema, taking into account an overlap of 10%, is combined with the rate of 7.5% found at proctoscopy, a frequency of about 14% emerges in detecting polyps in the rectum and in the colon. Thus, the fluoroscopic barium enema when combined with proctoscopy is a sensitive method in the detection of colorectal polyps. In addition, it has the advantage of rapid execution and relatively low cost.

    We wanted to evaluate the barium enema findings of milk allergy in infants. Retrospective evaluation of the plain abdominal radiography and barium enema findings was performed in fifteen young infants suffering with milk allergy. The presence of gaseous distension, rectal gas, paralytic ileus and mechanical obstruction was evaluated on the plain radiography. The presence of spasm, a transitional zone, a reversed rectosigmoid index and mucosal irregularity was analyzed on the barium enema; the presence of barium retention was also evaluated on 24-hour-delayed plain radiography. Paralytic ileus was the most common finding on the plain radiography (93%). On the barium enema, continuous spasm of the colon, ranging from the rectum to the descending colon, was revealed in ten infants (67%). A transitional zone was observed in one infant and a reversed rectosigmoid index was revealed in four. Mucosal irregularity was observed in two infants. Barium retention was demonstrated in 11 of fifteen cases: throughout the entire colon (n = 3), from the rectum to the descending colon (n = 7), and up to the transverse colon (n = 1). The most common barium enema finding of milk allergy in infants was spasm of the distal colon. The other findings were a transitional zone, a reversed rectosigmoid index, mucosal irregularity and barium retention.

    Full Text Available The research for not pollutants and renewable sources of energy, made the biodiesel is reused. But, its production generates the “Glycerin” (10% of biodiesel volume. This production is increasing and accumulating year by year, like other industrious by-products. With no law about discarding, scientists started to feed animals in different species with it. Rich in glycerol, it gives energy for animals and doesn't have other nutrients. It improves the alimentary conversion and does not change ruminal ambient or carcass production. For ruminants is used glycerin originated just from vegetables. This experiment aimed to discover what glycerin’s level can be used on diet. Made at the Unesp University of Campus of Jaboticabal, were used 24 heifers of Nellore in feedlot, weight of ± 265 kg in individuals stalls for 112 days. Were used three crossbreed cattle (Angus x Nellore castrated and cannulated, with ± 400 kg of weight for incubation. The “blond glycerin” used has 83% of glycerol. The proportion of Forage: Concentrate was 30:70. Corn silage was the forage. The concentrate was composed of: soy hulls, sunflower meal, urea and corn or corn more glycerin. All treatments had same percentages of protein and energy and were identified as “without glycerin” (G0, “with 10% of glycerin” (G10 and “20% of glycerin inclusion” (G20 in the dry matter of diet. Samples of food, leavings and excrements were collected. The collections of excrements were made at the superior part of them, without contact with the floor, at the moment of defecation for three consecutive days. Leavings and food were collected just before feeding. Bromatologics analyses were made according AOAC (1995, VAN SOEST and WINE (1967, HENDRIX (1993 and the digestion was made in autoclave (0,5 Kgf/cm2, 111ºC for 50 minutes, proceeding adapted of PELL and SCHOFIELD (1992.

    Crossbred heifers (n = 373; 421.6 kg +/- 28.9) were fed finishing diets containing 0, 2, 4, 8, 12, or 16% crude glycerin (DM basis). Diets consisted of steam-flaked corn with 6% alfalfa hay and 1.2% urea and provided 300 mg of monensin, 90 mg of tylosin, and 0.5 mg of melengestrol acetate per animal daily. Cattle were stratified by BW and allocated randomly, within strata, to concrete-surfaced feedlot pens each containing 6 to 7 heifers, with 9 pens per dietary treatment. Cattle were transitioned from the control diet to diets containing increasing proportions of glycerin over a period of 10 d. Cattle had ad libitum access to feed, and diets were delivered once daily throughout the 85-d trial period. As the concentration of glycerin increased, DMI decreased linearly (P glycerin had ADG of 1.19, 1.34, 1.29, 1.25, 1.17, and 1.03 kg, respectively (linear, P = 0.013; quadratic, P = 0.010). Feeding glycerin had a quadratic effect on G:F, and G:F was optimal when glycerin was fed at 2% of the diet (quadratic, P = 0.046). Glycerin increased the final BW by 12.7, 8.1, and 5.3 kg when fed at 2, 4, and 8% of the diet, respectively, but reduced the final BW by 1.9 and 14.3 kg when included at 12 and 16% of the diet (linear, P = 0.009; quadratic, P = 0.006). Similarly, HCW increased by 8.1, 5.1, and 3.3 kg when glycerin was fed at 2, 4, and 8% of the diet, respectively, but were 1.2 and 9.1 kg less than controls when glycerin was fed at 12 and 16%, respectively (linear, P = 0.009; quadratic, P = 0.006). Longissimus muscle area decreased linearly as glycerin concentrations increased (P glycerin resulted in linear decreases in subcutaneous fat over the 12th rib and marbling scores (P = 0.045). Glycerin tended to decrease the percentage of cattle grading USDA Choice (P = 0.084) and increase the percentage of cattle grading USDA Select. Adding glycerin to cattle-finishing diets improved BW gain and feed efficiency, particularly when added at concentrations of 8% or less on a DM

    The aim of the study is to investigate the effectiveness of Peristeen retrograde continence enema (RCE) in the management of faecal incontinence in children with spina bifida. We identified a homogenous group of spina bifida patients in whom RCE was initiated (Jan 2006-July 2013). Confidential assessments included (i) Fecal Incontinence Quality Of Life (FIQOL), (ii) St Marks Faecal Incontinence score, (iii) Cleveland Clinic Constipation score and (iv) Neurogenic Bowel Dysfunction score. Of 20 patients, 11 (mean age 14.5 ± 5.3 years) were male. Of 20 patients, nine were still using RCE (mean follow-up 4.1 years). Three patients ceased RCE within 10 days, six after 4-12 months and two after 36-48 months. Reasons for cessation included balloon difficulties (n = 4), procedure deemed too difficult (n = 4) and pain (n = 3). There were no differences between the groups in length of training time for technique, instillate fluid/volume used and time taken to perform RCE. There were no differences between the groups for quality of life, faecal incontinence or constipation scores. We demonstrated a high rate of cessation with RCE in patients with spina bifida. This could not be explained by associated conditions, or by enema-related parameters. One possible explanation is the lack of ongoing outpatient support for the children and their families. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Avicenna (980-1037 AD), also known as Sheikh or-Raeis, was an Muslim philosopher, physician, surgeon, astronomer, politician, encyclopedist, and mathematician. Avicenna's writings comprise of five books, know as the Al-Qanun fi al-Tibb (The Canon of Medicine) and the canon covers a wide variety of medical issues. This canon of medicine was the main reference for medical education in Western countries up until the 16th century and in the Middle East until the 19th century. Several chapters of the 3rd book of the Canon are devoted to a detailed description of gastrointestinal diseases including bowel obstruction, hemorrhoids anal fissures, perianal fistulas and perianal itching. Additionally, that same volume contains an illustration of an enema device. The aim of this paper was to present a brief review of Avicenna's 11th century views on bowel obstruction and to present his description of an enema device that has remained relatively unnoticed until now. Finally, this article illustrates similarities between Avicenna's explanation and modern medical science that celebrate Avicenna as an important contributor to medieval knowledge on gastrointestinal diseases, the science of which has been passed on to later generations.

    Full Text Available Glycerin is a major co-product resulting from biodiesel production, and it has been proposed as a highenergy source for use in swine diets. However, it is necessary to determine the nutritional value of neutral semi-purified glycerin (NSPG. In this study two experiments were carried out to determine the nutritional value, evaluated the performance and economic feasibility of starting piglets fed on neutral semi-purified glycerin. A digestibility trial (Experiment I was conducted using 30 crossbred barrows with an initial average body weight of 42.91±1.58 kg. The glycerin levels used in the digestibility assay were 4, 8, 12 and 16% of the basal diet (corn + soybean meal based. The digestible energy (DE and metabolizable (ME energy values of glycerin were estimated by regression of DE and ME (kcal/kg intake associated with glycerin vs. glycerin intake (kg. The values (as-fed-basis of DE and ME (kcal/ kg obtained were 3,298 and 2,531, respectively. In Experiment II, 100 piglets (50 gilts and 50 barrows with BW = 15.14±0.06 to 30.28±0.65 were allotted in a randomized design using four inclusion levels (3.5, 7.0, 10.5 and 14% of NSPG. There were ten replicates with two piglets per experimental unit. Additionally, a control diet containing no glycerin (0% was formulated. The results show it is feasible to use up to 14% NSPG in piglet feed without impairing performance and plasma chemistry.

    The colographic appearance of intussusception is variously described as a claw sign, pincer defect, shouldering effect, and coiled-spring pattern. This report adds a new radiographic sign to the list. An end-on view of an intussusception on barium enema shows a ring of contrast resembling a solar eclipse. Familiarity with this bizarre appearance is desirable, lest it may be mistaken for spillage of barium due to a colonic perforation.

    2014-02-01

    Full Text Available Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30 were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass characteristics were collected. In experiment 2, a digestibility trial was performed using indigestible acid detergent fiber (iADF as internal marker, and five rumen-cannulated steers. Both experiments were conducted as a randomized complete block design and data were analyzed using mixed procedures. In experiment 1 no differences were observed among treatments on dry matter intake, and performance variables. Regarding carcass characteristics, no effect was observed, except for carcass fat estimates, which were greater in treatments with crude glycerin. In experiment 2, crude glycerin promoted a decrease in digestibility of fibrous fractions NDF and HEM, and increased digestibility of crude protein by 6%. Although it caused negative effect on digestibility of fibrous fraction of diets, crude glycerin can be a good energy source for Nellore bulls, since no losses are observed on performance and carcass characteristics when animals are fed up to 30% of this by-product.

    To define whether volume of water, administered during water enema CT (WE-CT) for local staging of rectal cancer, may be reduced without compromising the diagnostic value of the examination. Materials and Methods: 29 patients with rectum cancer underwent preoperative WE-CT. Contrast-enhanced CT (equilibrium phase) measurements were performed after i.v. injection of smooth muscle relaxant and rectal administration of 400 - 500 ml lukewarm tap water. Quality of the obtained scans was evaluated and the images were analyzed for depth of tumor invasion. Results of the CT examinations were compared to findings at surgery. Results: Despite reduced dose of water enema, 19/29 examinations were of excellent quality, 6/29 good, and 4/29 poor, but still diagnostic. We achieved sensitivity (90.1), specificity (70.1) and accuracy (86.2) in differentiating tumors confined to the bowel wall from those extending beyond it. Conclusion: Large volume of water enema administered during CT examination of the rectum may cause complaints and increases the risk of complications. Our results prove that using lower amount of water does not impair the quality of examination and accuracy of local staging of rectum carcinomas. (orig.)

    The paper discusses a possibilities of usage a simple alcohols to fuelling of spark ignition engines. Methanol and blends of methanol with glycerin, being a waste product from production of bio-components to fuels based on rapeseed oil, have been used in course of the investigations. The main objective of the research was to determine possibilities of utilization of glycerin to blending of engine fuels. The investigations have been performed using the Fiat 1100 MPI engine. Parameters obtained with the engine powered by pure methanol and by methanol- glycerin mixtures with 10÷30%vol content of glycerin were compared to parameters of the engine fuelled conventionally with the E95 gasoline. The investigations have shown increase of overall efficiency of the engine run on pure methanol with 2.5÷5.0%, and run on the mixture having 10% addition of glycerin with 2.0÷7.8%. Simultaneously, fuelling of the engine with the investigated alcohols results in reduced concentration of toxic components in exhaust gases like: CO, THC and NOx, as well as the greenhouse gas CO2.

    Coffee enemas are believed to cause dilatation of bile ducts and excretion of bile through the colon wall. Proponents of coffee enemas claim that the cafestol palmitate in coffee enhances the activity of glutathione S-transferase, an enzyme that stimulates bile excretion. During video capsule endoscopy (VCE), excreted bile is one of the causes of poor preparation of the small bowel. This study aimed to evaluate the feasibility and effect of coffee enema for preparation of the small bowel during VCE. In this pilot study, 17 of 34 patients were assigned to the coffee enema plus polyethylene glycol (PEG) 2 L ingestion group, whereas the 17 remaining control patients received 2 L of PEG only. The quality of bowel preparation was evaluated in the two patient groups. Bowel preparations in the proximal segments of small bowel were not differ between two groups. In the mid and distal segments of the small intestine, bowel preparations tend to be better in patients who received coffee enemas plus PEG than in patients who received PEG only. The coffee enema group did not experience any complications or side effects. Coffee enemas may be a feasible option, and there were no clinically significant adverse events related to coffee enemas. More prospective randomized studies are warranted to improve small bowel preparation for VCE.

    Full Text Available Our objective was to evaluate the efficacy of daily enemas for the treatment of overactive bladder (OAB in children. This study was a prospective, controlled trial of 60 children with nonneurogenic OAB. The control patients (40 were treated with standard therapies, including timed voiding, constipation treatment with osmotic laxatives, anticholinergics, and biofeedback physical therapy, whereas the treatment patients (20 received only daily enemas and osmotic laxatives. On assessment of improvement of OAB symptoms, only 30% of the traditionally treated patients’ parents reported resolution of symptoms at 3 months, whereas 85% of enema patients did. At the onset of the study, the average pediatric voiding dysfunction score of all patients was 14, whereas on follow-up, the average scores for traditionally treated patients and enema-treated patients were 12 and 4, respectively. This study demonstrated that daily enema therapy is superior to traditional methods for the treatment of OAB.

    A series of H3PW12O40 nano-catalysts supported on silica-alumina (XH3PW12O40/SA (X = 10, 15, 20, 25, and 30)) with different H3PW12O40 content (X, wt%) were prepared, and they were applied to the dehydration of glycerin to acrolein. The effect of H3PW12O40 content on the physicochemical properties and catalytic activities of XH3PW12O40/SA nano-catalysts was investigated. Surface area and pore volume of XH3PW12O40/SA catalysts decreased with increasing H3PW12O40 content. Formation of H3PW12O40 aggregates was observed in the catalysts with high H3PW12O40 loading. Brønsted acidity of the catalysts showed a volcano-shaped trend with respect to H3PW12O40 content. It was revealed that yield for acrolein increased with increasing Brønsted acidity of XH3PW12O40/SA catalysts. Brønsted acidity of XH3PW12O40/SA catalysts served as a crucial factor determining the catalytic performance in the dehydration of glycerin. Among the catalysts tested, 25H3PW12O40/SA catalyst with the largest Brønsted acidity showed the best catalytic performance.

    Double-contrast barium enema has a reduced sensitivity in patients with severe sigmoid diverticulosis. Therefore a carboxy methyl cellulose enema was employed after the conventional double-contrast examination in 15 patients with sigmoid diverticulosis. A significant increase in lumen diameter and a superior removal of barium residue from the diverticulas facilitated the interpretation of the sigmoid loops. Conclusion: The addition of methyl cellulose enema to double-contrast barium imaging improves diagnostic imaging in diverticulosis by expanding the lumen and emptying the diverticulas. (orig.).

    To evaluate the effects of rectal enemas on rectal doses during postoperative high-dose-rate (HDR) vaginal cuff brachytherapy (VCB). This prospective trial included 59 patients. Two rectal cleansing enemas were self-administered before the second fraction, and fraction 1 was considered the basal status. Dose-volume histogram (DVH) values were generated for the rectum and correlated with rectal volume variation. Statistical analyses used paired and unpaired t-tests. Despite a significant 15 % reduction in mean rectal volume (44.07 vs. 52.15 cc, p = 0.0018), 35.6 % of patients had larger rectums after rectal enemas. No significant rectal enema-related DVH differences were observed compared to the basal data. Although not statistically significant, rectal cleansing-associated increases in mean rectal DVH values were observed: D{sub 0.1} {sub cc}: 6.6 vs. 7.21 Gy; D{sub 1} {sub cc}: 5.35 vs. 5.52 Gy; D{sub 2} {sub cc}: 4.67 vs. 4.72 Gy, before and after rectal cleaning, respectively (where D{sub x} {sub cc} is the dose to the most exposed x cm {sup 3}). No differences were observed in DVH parameters according to rectal volume increase or decrease after the enema. Patients whose rectal volume increased also had significantly larger DVH parameters, except for D{sub 5} {sub %}, D{sub 25} {sub %}, and D{sub 50} {sub %}. In contrast, in patients whose rectal volume decreased, significance was only seen for D{sub 25} {sub %} and D{sub 50} {sub %} (D{sub x} {sub %} dose covering x % of the volume). In the latter patients, nonsignificant reductions in D{sub 2} {sub cc}, D{sub 5} {sub cc} and V{sub 5} {sub Gy} (volume receiving at least 5 Gy) were observed. The current rectal enemas protocol was ineffective in significantly modifying rectal DVH parameters for HDR-VCB. (orig.)

    Glycyrrhizic acid diethyl ester (GZ-DE) was developed as a prodrug of glycyrrhizic acid (GZ), a hepatitis therapeutic drug. We fortuitously found that GZ-DE gels with glycerin selectively while searching for a safe solvent with which to dissolve GZ-DE. Based on this gelation, the aim of this study was to investigate the preparation of the gel and study the rheology, physicochemical and structural properties of the glycerin gel by differential scanning calorimeter (DSC), capillary electrophoresis (CEP), nuclear magnetic resonance (NMR), and small angle X-ray scattering (SAXS). The glycerin gel was prepared by the addition of at least 2.0% w/w GZ-DE. This gel did not flow at room temperature. After mixing glycerin and GZ-DE, a gel was formed after 2 days at 25°C or 3 h at 60°C. Glycerin gel containing 2.4% w/w GZ-DE provided the following results: 1) The glycerin gel exhibited creep at a constant stress of less than 10 Pa, but it is a fragile gel, showing Newtonian flow at 10 Pa stress. 2) Dynamic viscoelastic measurements showed that the elastic modulus (G') exceeds the viscous modulus (G''), indicating that glycerin gel has solid-like properties. 3) DSC showed a significant difference between the glass transition temperature of glycerin and glycerin gel. 4) CEP did not reveal a new compound in the glycerin gel. 5) NMR confirmed that glycerin gel is a physical gel. 6) SAXS measurements revealed that the glycerin gel has an oval-shaped basic frame (119 nm long and 65 nm wide).

    A thermal gravimetric analysis (TGA) and a differential scanning calorimetry (DSC) were carried out to characterize the water property and an alteration of lipid phase transition of stratum corneum (SC) by glycerin. In addition, the relationship between steady state skin permeation rate and skin hydration in various concentrations of glycerin was investigated. Water vapor absorption-desorption was studied in the hairless mouse stratum corneum. Dry SC samples were exposed to different conc. of glycerin (0-50%) followed by exposure to dry air and the change in weight property was monitored over time by use of TGA. In DSC study, significant decrease in DeltaH of the lipid transition in 10% glycerin and water treated sample: the heat of lipid transition of normal, water, 10% glycerin treated SC were 6.058, 4.412 and 4.316 mJ/mg, respectively. In 10% glycerin treated SCs, the Tc of water shifts around 129 degrees C, corresponding to the weakly bound secondary water. In 40% glycerin treated SC, the Tc of water shifts to 144 degrees C corresponding to strongly bound primary water. There was a good correlation between the hydration property of the skin and the steady state skin flux with the correlation coefficient (r2=0.94). As the hydration increased, the steady state flux increased. As glycerin concentration increased, hydration property decreased. High diffusivity induced by the hydration effect of glycerin and water could be the major contributing factor for the enhanced skin permeation of nicotinic acid (NA).

    Full Text Available ABSTRACT The objective of this study was to evaluate the physicochemical and nutritional characteristics of meat from three muscles of Ile de France lambs fed diets containing different levels of glycerin as an alternative to corn. Thirty non-castrated feedlot Ile de France lambs weighing 15±0.2 kg were housed in individual pens and slaughtered at 32±0.2 kg. Treatments consisted of three diets: sugarcane + 0% glycerin; sugarcane + 10% glycerin; and sugarcane + 20% glycerin; and three muscles were evaluated: triceps brachii, semimembranosus, and longissimus lumborum. No interactions were observed among glycerin levels and muscle types for the quality characteristics evaluated. Muscles were similar in terms of physicochemical and nutritional characteristics, and only differed in sarcomere length, diameter of muscle fibers, and cholesterol content. Dietary glycerin did not affect pH, water holding capacity (24 h and 30 days after slaughter, weight loss by thawing and cooking, shear force, diameter of muscle fibers, sarcomere length, lipid oxidation, chemical composition, or meat cholesterol content. Dietary glycerin resulted in a linear decrease of muscle yellowness from 3.99 to 3.29. Dietary glycerin altered intramuscular fat fatty acid profile, increasing the concentration of margaric acid (1.47 to 2.61%. Up to 20% glycerin can be included in the diet of feedlot lambs without any harm to meat quality.

    A small molecular organic depressor glycerine-xanthate was synthesized. The effect of glycerine-xanthate on the flotation of sulfide minerals was investigated based on a function of pH value and concentration of glycerine-xanthate through flotation experiments in the presence and absence of Cu2+. The results show that glycerinee-xanthate has a strong dressing effect on marmatite at pH>6 and on arsenopyrite in weak acid and base conditions with butyl-xanthate as collector. In the presence of glycerine -xanthate,marmatite is activated by addition of Cu2+, but arsenopyrite cannot be activated and remains unfloatable. So the selective separation can be achieved for two minerals. The depression of glycerine-xanthate on sulfide minerals was discussed based on the radical electronegative calculation and the theory of HSAB. Infrared spectrum shows that there are some -OH and -CSS- in glycerine-xanthate molecule, which competes with butyl-xanthate on the mineral surface. As a result of many hydrophilic groups in glycerine-xanthate, the surfaces of marmatite and arsenopyrite become hydrophilic, thus the flotation of marmatite and arsenopyrite is depressed. The collector is adsorbed preferentially on the surface of marmatite and it shows a better floatability in the presence of Cu2+, whereas, the surface of arsenopyrite absorbs glycerine-xanthate and the flotation of arsenopyrite is depressed by glycerine-xanthate.

    To evaluate the usefulness of sonography-guided Gastrografin enema for the diagnosis and treatment of meconium plug syndrome in premature newborns in a neonatal intensive care unit (NICU). Fifteen premature newborns underwent 23 sonography-guided Gastrografin enemas on the 8th day of life on average (range: 3 days-21 days). The gestational age and birth weight (mean{+-}standard deviation) of the patients were 29{+-}2 weeks and 999{+-}148 g, respectively. The diagnosis of meconium plug syndrome was based on relevant clinical and radiological findings. Diluted Gastrografin (1:3, 17-45 ml) was administered through a rectal tube under the guidance of sonography until it reached to the cecum. Thereafter, immediate post-procedure and delayed portable abdominal radiographs were taken. All the procedures were done within the NICU. We reviewed the dates of meconium evacuation and the first feeding after the last enema from the clinical data. Radiologically, the timing of the radiographic improvement after the last enema was checked. In cases of distended distal ileum with meconium on preenema sonography, follow-up sonography was performed to determine the interval change after gastrografin enema. None of the sonography-guided Gastrografin enemas performed within the NICU caused procedure-related complications. Meconium was evacuated within one day in all patients. In 14 patients, on average, feeding was started on the 7th day and radiographic improvement was observed on the 3rd day. Four of the five patients showing a distended distal ileum with meconium revealed a decrease in ileal distension on follow-up sonography. On the other hand, the other patient, who did not show such a decrease on follow-up sonography, was found to have ileal stenosis during subsequent surgery. Sonography-guided Gastrografin enema is a safe and effective bedside procedure, when performed in the NICU for the diagnosis and treatment of meconium plug syndrome.

    To evaluate the pattern of colonic diverticulosis according to age and sex, and recent trend. The authors retrospectively reviewed 120 cases of colonic diverticulosis in 1,020 patients who had undergone a double contrast barium enema examination between January 1st, 1993, and December 31st, 1995, and analyzed the frequency, size, multiplicity and anatomical site, according to age and sex. Diverticulum size was classified into one of three groups : less than 5mm, 5-10mm, over 10mm in diameter. The overall incidence of colonic diverticulosis was 120 cases among 1,020 patients(11.8%) with an incidence 5.3 times higher in males than in females. Peak incidence was in the fifth decade, with 19 cases (15.8%) among males, and after the sixth decade, with four cases(3.3%) among females. Mean age was 57.7 years. Diverticulum size of 5-10mm in diameter was predominant (2% of cases); average diameter was 5-6mm. The incidence of colonic diverticulosis was 5.1 times more frequent in the right colon (101 cases) than in the left (20 cases). The overall incidence of colonic diverticulosis has continually increased; in addition it has also recently increased slightly in left-sided colon. This is thought to be due to various factors, both congenital and acquired, including longer life with good health care, constipation, irritable bowel syndrome, stress and the tendency of eating patterns to more closely resemble those of the west.

    A case of abdominal actinomycosis is described in a woman with recurrent right lower abdominal pain and low-grade fever without history of appendectomy. Past history included the use of an intrauterine device (IUD) until 10 years before manifestation of these symptoms. We followed up the patient, via diagnostic imaging, for 7 months. On initial barium enema, a polypoid lesion was visualized at the bottom of the cecum and there was constriction of the sigmoid colon; the appendix was not seen. Seven months later, poor extension at the cecum, severe constriction in the sigmoid colon, and narrowing of the terminal ileum were also visualized. On computed tomography (CT), the lesion was initially localized only in the ileocecal region adjacent to the sigmoid colon. After 7 months, the lesion had infiltrated adjacent anatomic components and showed direct infiltration of the pelvic space. Differential diagnosis was difficult, as it was not obvious whether this was a pelvic abscess due to inflammation or appendiceal carcinoma. Laparotomy was performed. Macroscopically, the lesion was not limited to the ileocecal region, but involved the right ureter, tubes the Fallopian and ovary, bladder, psoas muscle, and abdominal wall. Pathology findings showed, chronic inflammatory tissue with evidence of actinomycosis. Although previous reports have described a lack of specific findings in this disease. When actinomycosis is suspected, CT is recommended to define its extent.

Enemas can be very effective but may cause serious adverse events, such as perforation or metabolic derangement. Our aim was to evaluate the outcome of the use of cleansing enema for acute constipation and to assess adverse events within 30 days of therapy. Methods: We performed a two-phase study: an initial retrospective and descriptive study in 2010, followed by a prospective study after intervention, in 2011. According to the results of the first phase we established guidelines for the treatment of constipation in the Emergency Department and then used these in the second phase. Results: There were 269 and 286 cases of severe constipation in the first and second periods of the study, respectively. In the first study period, only Fleet® Enema was used, and in the second, this was changed to Easy Go enema (free of sodium phosphate. There was a 19.2% decrease in the total use of enema, in the second period of the study (P < 0.0001. Adverse events and especially, the perforation rate and the 30-day mortality in patients with constipation decreased significantly in the second phase: 3 (1.4% versus 0 (P = 0.0001 and 8 (3.9% versus 2 (0.7% (P = 0.0001, for perforation and death in the first and second period of the study, respectively. Conclusion: Enema for the treatment of acute constipation is not without adverse events, especially in the elderly, and should be applied carefully. Perforation, hyperphosphatemia (after Fleet Enema, and sepsis may cause death in up to 4% of cases. Guidelines for the treatment of acute constipation and for enema administration are urgently needed. Keywords

    An increasing worldwide interest in alternative fuel sources and in a more diversified energy matrix has provided incentives for the biodiesel industry, generating large amounts of the by-product crude glycerin, a potential alternative feed for dairy cows. A replicated 3×3 Latin square study was conducted to evaluate the effects of high concentrations of crude glycerin on dry matter intake, milk yield and composition, milk fatty acid profile, and blood metabolites of medium-yield cows. Ruminally cannulated Holstein cows (n=6; 587 ± 39 kg of body weight; 114 ± 29 d in milk; and 20 ± 1.5 kg/d milk yield) were used in the study. The experimental period included 2 wk for adaptation and 1 wk for data collection. Cows were fed diets containing 0 (control), 15, or 30% crude glycerin (83% glycerol). Cows were milked, milk weights were recorded twice daily, and milk samples were collected for milk quality analyses at d 18 and 19 in each experimental period. Feeding cows with crude glycerin linearly decreased dry-matter intake, the 3.5% fat-corrected milk, and the solid-corrected milk yield. Hepatic enzymes were not affected by dietary treatments, except gamma-glutamyl transferase, which was decreased with the 15% crude glycerin diet. Serum glucose and albumin showed quadratic effect with increasing inclusion of crude glycerin. Plasma cholesterol as well as total protein linearly decreased with increasing inclusion of crude glycerin. Milk fat concentration and yield showed a quadratic effect of treatments. Solid yield decreased linearly with increasing inclusion of crude glycerin. Odd-chain fatty acids and conjugated linoleic acid in milk fat linearly increased with addition of crude glycerin in the diets. Together, these results suggest that crude glycerin has potential to replace corn; however, feeding diets in which corn is replaced with crude glycerin at 30% of dietary DM greatly reduces animal performance.

    The purpose of the present work was to optimise the filtration and dose setting for double-contrast barium enema examinations using a Philips MultiDiagnost Eleva FD system. A phantom study was performed prior to a patient study. A CDRAD phantom was used in a study where copper and aluminium filtration, different detector doses and tube potentials were examined. The image quality was evaluated using the software CDRAD Analyser and the phantom dose was determined using the Monte Carlo-based software PCXMC. The original setting [100 % detector dose (660 nGy air kerma) and a total filtration of 3.5 mm Al, at 81 kVp] and two other settings identified by the phantom study (100 % detector dose and additional filtration of 1 mm Al and 0.2 mm Cu as well as 80 % detector dose and added filtration of 1 mm Al and 0.2 mm Cu) were included in the patient study. The patient study included 60 patients and up to 8 images from each patient. Six radiologists performed a visual grading characteristics study to evaluate the image quality. A four-step scale was used to judge the fulfillment of three image quality criteria. No overall statistical significant difference in image quality was found between the three settings (P > 0.05). The decrease in the effective dose for the settings in the patient study was 15 % when filtration was added and 34 % when both filtrations was added and detector dose was reduced. The study indicates that additional filtration of 1 mm Al and 0.2 mm Cu and a decrease in detector dose by 20 % from the original setting can be used in colon examinations with Philips MultiDiagnost Eleva FD to reduce the patient dose by 30 % without significantly affecting the image quality. For 20 exposures, this corresponds to a decrease in the effective dose from 1.6 to 1.1 mSv.

    An energy balance experiment was conducted to determine the AME(n) of various crude glycerin samples, and to generate an equation to predict AME(n) of crude glycerin based on its chemical composition. Dietary treatments consisted of a corn-soybean meal basal diet with no added glycerin and a basal diet supplemented with 6% glycerin. Crude glycerin samples were obtained from biodiesel production facilities throughout the United States, which use a variety of lipid products as their initial feedstock. Two identical energy balance trials were conducted. In each trial, 864 male broilers (Ross × Ross 708) were fed a common starter diet until 17 d of age when they were switched to 1 of 12 experimental diets (6 replicates per treatment) from 17 to 22 d of age, with a 48-h collection period on d 21 and 22. Nitrogen-corrected apparent metabolizable energy values of crude glycerin samples were estimated by difference, whereby AME(n) of the basal diet was subtracted from the complete diet containing the test ingredient. The AME(n) of the basal diet and US Pharmacopeia-grade glycerin were determined to be 3,085 and 3,662 kcal/kg, respectively, whereas the AME(n) of the 10 crude glycerin samples ranged from 3,254 to 4,134 kcal/kg. Two crude glycerin samples had high levels of fatty acids compared with the other samples (24 and 35% vs. glycerin samples (3,806 vs. 3,611 kcal/kg, P glycerin samples, the stepwise regression equation to predict AME(n) was determined to be: [AME(n) (kcal/kg) = 1,605 - (19.13 × % methanol) + (39.06 × % fatty acid) + (23.47 × % glycerin)]; (R(2) = 0.25; SE = 379; P ≤ 0.01). These data indicate that glycerin is a good source of energy for broilers, and the AME(n) of glycerin is dependent on fatty acid, methanol, and water contents.

    Full Text Available Introduction: ulcerative colitis is a little known chronic inflammatory disease in colonic mucosa. The positive effect of epidermal growth factor was shown in a previous report, with enema use for treatment of mild to moderate left-sided manifestation of the disease. This evidence provided the basis for evaluating the efficacy and safety profile of a viscous solution of this product. Methods: thirty-one patients were randomized to three groups for daily medications during 14 days. Twelve received one 10 mg enema of epidermal growth factor dissolved in 100 mL of viscous solution whereas nine were treated with placebo enema; both groups also received 1.2 g of oral mesalamine per day. The other group included ten patients with 3 g / 100 mL of mesalamine enema. Primary end point was clinical responses after two weeks of treatment, defined as a decreased of, at least three points from baseline, the Disease Activity Index and endoscopic or histological evidences of improvement. Results: remission of disease was observed in all patients in the epidermal growth factor group, and six in both, mesalamine enema and placebo group. All the comparisons between groups showed statistically significant superiority for epidermal growth factor, the only product with significant reduction in disease activity index as well as the presence and intensity of digestive symptoms in patients after treatment. None adverse event was reported. Conclusions: the results agree with previous molecular and clinical evidences, indicating that the epidermal growth factor is effective to reduce disease activity and to induce remission. A new study involving more patients should be conducted to confirm the efficacy of the epidermal growth factor enemas.

    Full Text Available Introduction & Aims: The study aims to investigate barium enema accuracy in diagnosing Hischsprung's disease (HD. Patients & Methods: This study was performed on 58 patients diagnosed with Hischsprung's disease later confirmed by pathology; the patients had undergone surgical operation in the last 3 years. The radiographs were reached from their medical records and were later assessed by a skilled pediatric radiologist. Bar-ium enema findings were also evaluated. Rectosig-moid index with the sign of transitional zone (TZ, and barium evacuation of delayed radiographs were recorded by a radiologist. Results: We measured accuracy of rectosigmoid index in these patients to be 94.8%, the sign of TZ to be 70.7%, and the barium evacuation of delayed radio-graphs to be 100% for diagnosis of HD. Fifty percent of the cases were neonates, 42% infants, and 7% more than 2 years old. Of all the patients, 76% were male and 24% were female. The most common diseases accompanying HD were cardiac abnormalities. We did not find any total aganglionosis. Conclusion & Discussion: Half of the patients were newborn infants. The fact that the ratio is more than usual shows timely diagnosis of the condition by phy-sicians of this center. Barium enema findings in new-borns of our study contradicted significantly the re-searches done in other countries. In this study, it was found that with increasing age, barium enema find-ings would be defined in such a way that in in-fantsover 2 years, it can reach a diagnosis accuracy of up to 100%. Regarding the availability of barium en-ema and its lower costs than other diagnostic meth-ods, its accuracy seems very promising. Our study emphasizes that perhaps with barium enema, we may operate these infants in one stage so that they can get rid of multiphasic operation difficulties.

    In this study, a novel 5-Fluorouracil (5-FU) enema with good bio adhesion and temperature sensitivity was developed using in situ gelling technology. The preparation was formulated as a free-flowing liquid before use, while a layer of gel film was quickly formed when administered in the rectum, with a large contact surface area. It also demonstrated good biocompatibility, appropriate gel strength and bio adhesive force with excellent adhesion to rectal mucosa and prolonged action time, allowing more effective drug absorption and diffusion to surrounding tissues. Poloxamer 407 and poloxamer 188 were applied to adjust the gelling temperature. With the addition of carbopol and polycarbophil (bio adhesive substances), the solubility of 5-FU and gel strength increased, the temperature of gelation and the surface area of drug contact on mucous epithelium decreased. Decreased adhesive force between the preparation and the mucous membrane of the rectum was demonstrated with improving carbopol and polycarbophil's concentration. In vitro release demonstrated that 5-FU in situ gelling enema with different bases had a rapid and almost complete drug release. We used an optimized formulation of P407/P188/polycarbophil/5-FU (17/2.5/0.2/1.0) for animal experiments. The result showed that the drug evenly covered the surface of the rectum and there was no leakage in 6 hours. The in situ gelling enema showed significantly higher rectal tissue levels of 5-FU compared with suppository and intravenous administration, indicating that 5-FU could be well absorbed due to the enlarged releasing area, longer retention time and larger amount of dissolved active ingredients. Systemically, 5-FU levels in the enema group were similar to those in the suppository group and significantly lower than the intravenous group. The enema was not associated with morphological damage to rectal tissue. These results suggest that the bio adhesive and in situ gelling enema could be a more effective rectal

The aims of the present work were to evaluate the effect of crude glycerine on back-fat thickness and the proximate composition of pork and to examine the effect on pork quality of using growing-finishing feeds with different percentages of crude glycerine added. For this purpose 60 crossbreed (Large White × Landrace barrows were subdivided into three groups according to the crude glycerine concentration administered in feed: C, control diet, no crude glycerine; and G2.5 and G5 with 2.5% and 5% added crude glycerine, respectively. This study evaluated proximate composition, pH, cooking losses, texture, colour coordinates, fatty acid profile, and sensorial analysis. No differences were found in any of the three groups studied (C, G2.5, G5 for measurements performed both before (with ultrasound equipment and after slaughter (millimetre ruler. The proximate composition and the physical-chemical parameters of longissimus dorsi were similar between groups. There were no differences detected (p>0.05 between the three groups as regards the CIELab coordinates, textural profile and sensory attributes. Therefore, 5% crude glycerine to replace corn could be used as an ingredient in pig feed without appreciably affecting the back-fat and meat quality characteristics.

    The objective was to evaluate the fatty acid profile and qualitative characteristics of meat from young bulls fed crude glycerin. Forty-four animals with an initial live weight of 368 ± 4 kg were used in a completely randomized design, with four treatments: no glycerin or addition of 6, 12 or 18% glycerin. The animals were slaughtered with 519.5 ± 14.9 kg of live weight. The meat characteristics assessed were chemical composition, shear force, fatty acid concentration, color and lipid oxidation. The addition of glycerin increased the content of ether extract (P<0.05) in the muscle. A linear increase was observed (P<0.05) in the oleic acid contents (C18:1 cis 9). The saturated fatty acid (SFA) contents linearly decreased in the muscle as a function of glycerin addition. The lightness (L*) and yellowness (b*) indices increased with the use of crude glycerin (P<0.05). The crude glycerin increased the intramuscular fat and oleic acid content in the longissimus dorsi muscle. © 2013.

    Full Text Available The objective of this research was to evaluate the effect of crude glycerin in the supplement provided in creep feeding on the physico-chemical and sensory characteristics of meat from suckling lambs kept in pasture ryegrass. Thirty two suckling lambs, sixteen male and sixteen female, were distributed into 4 diets with different concentrations of crude glycerin: 0, 10, 20 and 30% crude glycerin, in the replacement of corn, in the isoproteic supplement (18% CP provided daily in amounts equivalent to 2% of body weight. The experimental design was randomized blocks, with each variable data submitted to analysis of variance at 5% significance and the significant results subjected to regression analysis. There was no effect (P>0,05 of contents of crude glycerin on the chemical composition and cholesterol content of lamb meat. On the other hand, there was increased linearly (P>0,05 pH and cooking losses by the use of crude glycerin. No influence (P>0,05 of crude glycerin concentration on the texture profile analysis (TPA, sensorial analysis by triangular test and even when was evaluated attributes color, tenderness and juiciness of lamb meat. Up to 30% of crude glycerin in the supplement provided in creep feeding for suckling lambs grazing ryegrass do not compromise the physical-chemical and sensorial quality of the lamb meat.

    Full Text Available Serum is widely used for the purpose of monitoring and diagnosis support for most of poultry diseases. In the case of the serum plate agglutination test (SPA, commonly used to detect antibodies for Salmonella Pullorum (SP, Mycoplasma gallisepticum (MG and Mycoplasma synoviae (MS, serum cannot be frozen because it may result in false positive. Without freezing, serum can last only for a few days. In this experiment, glycerin was evaluated as a serum preservering agent. About 50 samples for each disease and analyzed by SPA test previously were separated. Glycerin was added to serum from commercial chickens, with and without antibodies for SP, MG and MS, in the proportion of 1:1 (serum:glycerin and kept at refrigerated conditions (2 to 8 ºC. For four years they were tested by the SPA, initially weekly, afterward monthly and then annually. The results show that serum with glycerin give consistent and valid results according to the kind of antibodies present for the period tested. Sera that glycerin was not added to, the results were valid only for the first week. From the second week on, microbial growth affected the test results of the sera without glycerin. Our investigation shows that glycerin can be used to preserve chicken serum for SPA under refrigerated conditions. It is an easy, simple and cheap procedure that can extend serum shelf life, useful mainly for control sera.

    Full Text Available This study evaluated the use of crude glycerin as an alternative of energy generation to replace the traditional fuels. The Tradescantia stamen hair mutation assay (Trad-SH was applied to study the mutagenic effects caused by the emissions generated in the direct combustion of diesel oil and glycerin in a flame tube furnace. Tradescantia inflorescences were exposed to gaseous emissions from the combustion tests in a fumigation chamber for 30-40 min. The analysis of variance and the Tukey test were applied to compare the differences between six test groups (intoxicated with emissions from glycerin and diesel oil combustion and a control group. Only one glycerin group showed statistical differences (0.05, possibly due to the complexity of the burning process and impurities, besides the acrolein present in its emissions. The high heating value (HHV of crude glycerin (25.5 MJ/kg was lower than diesel oil (45.19 MJ/kg, but it was comparable to other fuels. Although the use of glycerin as a biofuel could be an important aspect to be considered, the results showed that the glycerin had a substantial mutagenic potential similar to that of diesel oil.

    Full Text Available Background: Non-surgical reduction remains the first line treatment of choice for intussusception. The major complication of air enema reduction is bowel perforation. The authors developed a custom made pressure release valve to be added to portable insufflation devices, delivering air at pressures accepted as safe for effective reduction of intussusception in children under fluoroscopic guidance. The aim of this study was to develop a custom made pressure release valve that is suitable for the insufflation devices used for air enema reduction of intussusception and to put this valve into regular clinical practice. Materials and Methods: An adjustable, custom made pressure release valve was assembled by the authors using readily available components. The valve was coupled to a simple air enema insufflation device. The device was used for the trial of reduction of intussusception in a prospective study that included 132 patients. Results: The success rate for air enema reduction with the new device was 88.2%. The mean pressure required to achieve complete reduction was 100 mmHg. The insufflation pressure never exceeded the preset value (120 mmHg. Of the successful cases, 58.3% were reduced from the first attempt while 36.1% required a second insufflation. Only 5.55% required a third insufflation to complete the reduction. In cases with unsuccessful pneumatic reduction attempt (18.1%, surgical treatment was required. Surgery ranged from simple reduction to resection with a primary end to end anastomosis. No complications from air enema were recorded. Conclusions: The authors recommend adding pressure release valves to ensure safety by avoiding pressure overshoot during the procedure.

    To evaluate the radiologic findings of granulomatous colitis on double contrast barium enema and changes on follow-up studies. Serial double contrast barium enema of six patients with granulomatous colitis confirmed by endoscopic biopsy were reviewed. We analyzed the radiologic findings and their follow-up changes, including aphthous ulcers, lymphoid hyperplasia, deep ulcers, cobble stone appearance, geographic ulcers, asymmetric involvement of ulcers, skip lesions, sinus tract, fistula formation, pseudosacculation, focal stricture, and small bowel involvement. Pretreatment double contrast barium enema findings were aphthous ulcers in five patients, deep ulcer in six, cobble stone appearance in five, longitudinal geographic ulcers in two, fistulas in one, pseudosacculations in two, focal stricture in one, and pseudopolyps in six. Also, anal ulcers were observed in two patients, asymmetric involvement of ulcers in three, skip lesions in four, and small bowel involvement in five in five patients proved to have inactive disease after treatment, aphthous ulcers and deep ulcers disappeared. Geographic ulcers of two patients and anal ulcer of one patients decreased in size or depth. Pseudosacculation in one patient disappeared. Pseudopolyps decreased in two patients, increased in one, and decreased after increase in two. One patient whose disease remained active after treatment showed maintenance or increase of ulcers or fistula. And their pseudosacculation or focal stricture unchanged and pseudopolyps decreased. The major radiologic findings of chronic granulomatous colitis on double contrast barium enema are aphthous ulcer, deep ulcer, cobble stone appearance, discontinuity of the lesion and coexistence of ulcers and pseudopolyps. And, double contrast barium enema is good follow-up modality because its findings correlate with clinical course of the granulomatous colitis after treatment.

The aim of this study was to evaluate the addition of crude glycerin in the anaerobic digestion of cassava starch industry effluent (cassava wastewater, in a horizontal semi-continuous flow reactor of one phase in laboratory scale. It was used a reactor with a 8.77 L of useful volume, a medium support for corrugated conduit of polyvinyl chloride (PVC, temperature of 261 ºC, fed with cassava wastewater and glycerin, with hydraulic detention times of 4 and 5 days and increasing volumetric organic load of 3.05; 9.32; 14.83 and 13.59 g COD L-1 d-1, obtained with the addition of glycerin at 0; 2; 3 and 2% (v/v, respectively. The average removal efficiencies of TS and TVS were decreasing from the addition of glycerin to the cassava wastewater, averaging 81.19 to 55.58% for TS and 90.21 to 61.45% for TVS. The addition of glycerin at 2% increased the biogas production compared to the control treatment, reaching 1.979 L L-1 d-1. The biogas production as a function of the consumed COD was higher for the control treatment than for the treatments with addition of glycerin, which indicates lower conversion of organic matter into biogas.O Programa Nacional de Produção e Uso do Biodiesel introduziu o biodiesel na matriz energética brasileira, trazendo a perspectiva de aumento da oferta de glicerina, coproduto gerado na proporção de 10 kg para cada 100 L de biodiesel.

    To be discarded into the environment, cassava wastewater, generated during the processing of the cassava root, needs to be dealt with trying to reduce its organic load and total solids, harmful to water bodies. As for crude glycerin, a byproduct of biodiesel production, need alternatives to its destination, because the cost to its purification is often not feasible, preventing its use by pharmaceutical and food industries. In this study we chose to anaerobic digestion to treat manipueira assessing the behavior of the reactor with the addition of glycerin. The reactor was constructed of PVC with 60cm long, 20cm in diameter and a volume of 8.38 L, and HRT was 5 days. Three treatments were applied: T1, only manipueira, T2 with 0.25% glycerol and T3, with 0.50%. The three treatments showed a great reduction of organic load (above 90%) and higher with the addition of 0.25% crude glycerine. The highest mean removal of solids and total volatile solids occurred in treatment with 0.50% crude glycerine, being 84.18% and 91.41% respectively. (author)

    There is considerable interest in using crude glycerin from biodiesel production as a heating fuel. In this work crude glycerin was emulsified into fuel oil to address difficulties with ignition and sustained combustion. Emulsions were prepared with several grades of glycerin and two grades of fuel oil using direct and phase inversion emulsification. Our findings reveal unique surfactant requirements for emulsifying glycerin into oil; these depend on the levels of several contaminants, including water, ash, and components in MONG (matter organic non-glycerin). A higher hydrophile-lipophile balance was required for a stable emulsion of crude glycerin in fuel oil compared to water in fuel oil. The high concentration of salts from biodiesel catalysts generally hindered emulsion stability. Geometric close-packing of micelles was carefully balanced to mechanically stabilize emulsions while also enabling low viscosity for pumping and fuel injection. Phase inversion emulsification produced more stable emulsions than direct emulsification. Emulsions were tested successfully as fuel for a waste oil burner.

    Full Text Available The objective of this study was to evaluate the economic returns of crossbred calves grazing on pastures formed by Urochloa brizantha fed crude glycerin as a supplement. Thirty-six crossbred calves with initial average weight of 301.5 kg were distributed in a completely randomized design with four treatments and nine replicates per treatment. The animals were maintained on rotational grazing production of Urochloa brizantha cv. Marandu. The tested treatments were 0.0, 3.33, 6.66 and 9.99% inclusion of crude glycerin in the total dry matter as a substitute for corn. The production of meat was not altered by the inclusion of glycerin in the diet. The inclusion of glycerin caused a reduction of up to 14.93% in the price of the concentrate. There was a significant increase in the total balance, which rose from 3.76 to 91.89 R$/ha with the inclusion of glycerin. The inclusion of crude glycerin in the supplement was capable of raising the net present value and the internal rate of return, proving to be an alternative to reduce the cost of production of supplemented pastured animals.

    Full Text Available ABSTRACT The objective of this research was to evaluate the performance of anaerobic co-digestion of swine excreta associated with increasing doses of crude glycerin and different hydraulic retention times (HRT. A completely randomized design was adopted in a 3 × 4 factorial arrangement composed of three HRT (10, 17, and 24 days and four crude glycerin doses (0, 5, 10, and 15 g/100 g of total solids [TS], with four replications per treatment. The assessed parameters were: biogas production potential, reductions of volatile solids (VS, chemical oxygen demand (COD, and most probable number of total and thermotolerant coliforms. The biogas production per added VS presented quadratic effect at 17 and 24 days of HRT, with ideal doses of 5.5 and 5.9 g of crude glycerin/100 g TS, respectively. There was no difference among glycerin doses at 10-day HRT for VS reductions; however, at HRT of 17 and 24 days, there were differences, with greater reduction of 61.1% for 5 g of crude glycerin/100 g TS at 24-day HRT. The COD reduction values showed an effect among retention times, in which the 24-day HRT provided the best results. Reductions in coliforms were greater than 99%, with no difference among treatments. Addition of 5 to 6 g of crude glycerin/100 g TS with a 24-day HRT is more effective in biogas production and reduction of VS, COD, and coliforms from co-digestion of swine excreta.

    Usually, a plasticizer is a relatively low-viscosity liquid ingredient that is added to improve the mechanical properties and the processing properties of a propellant, such as a lower viscosity for casting or a longer pot life of the mixed, but uncured propellant. The effects of many plasticizers on the performance of the composite propellant have been studied in detail. Glycerin is a triol, a low viscosity material, and inexpensive. It seems that the processing properties and the mechanical properties of the HTPB binder would be improved by the addition of glycerin. The curing behavior, the mechanical properties, and the thermal decomposition of a glycerin/HTPB blend have been investigated in this study. The viscosity of the glycerin/HTPB blend and the increasing ratio of the viscosity versus the elapsed time are lower than those of only HTPB. The mechanical properties are improved by the addition of glycerin, even for a low quantity of glycerin. The thermal decomposition behavior of the blend occurs at lower temperatures when compared to that of HTPB. (Abstract Copyright [2009], Wiley Periodicals, Inc.)

    We study the dynamics of a spherical gaseous bubble created by focusing a nanosecond laser pulse at 532 nm into a large volume of glycerin-water solutions. Free oscillation of the bubble and shock wave emission from the bubble dynamics are recorded by a high-speed camera together with a pulse laser stroboscope; concurrently, pressure radiated from the oscillating bubble is measured by a hydrophone. The bubble achieves a mechanical equilibrium after free oscillation is damped out; the equilibrium state stays for a while, unlike vapor bubbles. We speculate that the bubble content is mainly gases originally dissolved in the liquid (i.e., air). The bubble dynamics we observed are compared to Rayleigh-Plesset-type calculations that account for diffusive effects; the (unknown) initial pressure just after laser focusing is tuned to obtain agreement between the experiment and the calculation. Moreover, viscous effects on the shock propagation are examined with the aid of compressible Navier-Stokes simulation.

    AIMS: To compare the subjective acceptability of CT colonography in comparison with barium enema in older symptomatic patients, and to ascertain preferences for future colonic investigation. MATERIALS AND METHODS: The study population comprised 78 persons aged 60 years or over with symptoms suggestive of colorectal neoplasia, who underwent CT colonography followed the same day by barium enema. A 25-point questionnaire was administered after each procedure and an additional follow-up questionnaire a week later. Responses were compared using Wilcoxon matched pairs testing, Mann-Whitney test statistics and binomial exact testing. RESULTS: Participants suffered less physical discomfort during CT colonography (p=0.03) and overall satisfaction was greater compared with barium enema (p=0.03). On follow-up, respondents reported significantly better tolerance of CT colonography (p=0.002), and were less prepared to undergo barium enema again (p<0.001). Of 52 subjects expressing an opinion, all preferred CT to barium enema. CONCLUSION: Patient satisfaction was higher with CT colonography than barium enema. CT colonography caused significantly less physical discomfort and was overwhelmingly preferred by patients.

    About one-half of patients with meconium ileus (MI) present with a complication such as volvulus, atresia, meconium peritonitis or giant cystic meconium peritonitis. The treatment of these complications requires surgery. However, the preoperative diagnosis of complicated MI is difficult. We describe two neonates with complicated small-bowel obstruction, one with MI related to cystic fibrosis and the other not related to cystic fibrosis. In both, contrast enema depicted a spiral appearance of the distal small bowel, which at surgery proved to be the result of volvulus associated with antenatal bowel perforation. This appearance of the small bowel on contrast enema in this clinical setting has not been previously described. The recognition of this spiral appearance of the distal small bowel suggests the need for surgery. (orig.)

    AIM: To assess Magnetic resonance colonography with fat enema as a method for detection of colorectal neoplasm. METHODS: Consecutive twenty-two patients underwent MR colonography with fat enema before colonoscopy. T1-weighted three-dimensional fast spoiled gradientecho with inversion recovery sequence was acquired with the patient in the supine position before and 75 s after Gadopentetate Dimelumine administration. Where by, pre and post MR coronal images were obtained with a single breath hold for about 20 s to cover the entire colon. The quality of MR colonographs and patients' tolerance to fat contrast medium was investigated. Colorectal neoplasms identified by MR colonography were compared with those identified on colonoscopy and sensitivity of detecting the lesions was calculated accordingly. RESULTS: MR colonography with fat enema was well tolerated without sedation and analgesia. 120 out of 132 (90.9%) colonic segments were well distended and only 1 (0.8%) colonic segment was poor distension. After contrast enhancement scan, mean contrast-to-noise ratio (CNR) value between the normal colonic wall and lumen was 18.5 ± 2.9 while mean CNR value between colorectal neoplasm and lumen was 20.2 ± 3.1. By Magnetic resonance colonography, 26 of 35 neoplasms (sensitivity 74.3%) were detected. However, sensitivity of MRC was 95.5% (21 of 22) for neoplasm larger than 10 mm and 55.6% (5 of 9) for 5-10 mm neoplasm. CONCLUSION: MR colonography with fat enema and T1-weighted three-dimensional fast spoiled gradientecho with inversion recovery sequence is feasible in detecting colorectal neoplasm larger than 10 mm.

For variables in which the F test was considered significant, the statistical interpretation of the effect of CG substitution levels was carried out through regression analyses. Kinetic parameters were not affected by CG inclusion. On in vitro NDF degradation, a significant effect of CG levels was observed on the potentially degradable fraction of NDF, the insoluble potentially degradable fraction of NDF, and the undegradable NDF fraction. The intake and digestibility of nutrients and nitrogen balance were not affected by CG inclusion. The CG levels change in vitro NDF degradability parameters; however, there were no changes in animal intake, digestibility, and nitrogen balance with the inclusion levels used.

    The energy value of crude glycerin from different biodiesel production facilities was determined in nursery pigs (initial BW of 10.4 kg) to predict apparent DE and ME based on the composition of crude glycerin. Dietary treatments consisted of a basal diet, or diets containing crude glycerin from various biodiesel production facilities supplemented in the diet at approximately 9.1%. Because of bulk density differences, 2 glycerin products were supplemented at either 7.7 or 6.9%. In addition, soybean oil and lard were included at 6.7% as 2 dietary treatments to serve as positive controls. Each diet was fed twice daily to pigs in individual metabolism crates. After a 6-d adjustment period, a 4-d balance experiment was conducted. During the collection period, feces and urine were collected daily and stored at 0 degrees C until analysis. The GE of each test ingredient and diet and of urine and fecal samples from each pig were determined by isoperibol bomb calorimetry. The DE and ME values of crude glycerol were estimated by difference, whereby the DE and ME content of the basal diet was subtracted from the complete diet containing the test ingredient. Gross energy, DE, and ME of US Pharmacopeia grade glycerin were determined to be 4,325, 4,457, and 3,682 kcal/kg, respectively. In contrast, GE of the crude glycerin samples ranged from 3,173 to 6,021 kcal/kg, DE ranged from 3,022 to 5,228 kcal/kg, and ME ranged from 2,535 to 5,206 kcal/kg, reflecting the content of glycerol, methanol, and FFA in the crude glycerin. The GE, DE, and ME of soybean oil and lard were determined to be 9,443, 8,567, and 8,469 kcal/kg, and 9,456, 8,524, and 8,639 kcal/kg, respectively. The stepwise regression prediction of the ME in crude glycerin exhibited R(2) of only 0.41 [ME, kcal/kg (as-is basis) = (37.09 x % of glycerin) + (97.15 x % of fatty acids)], whereas prediction of GE achieved an R(2) of 0.99 [GE, kcal/kg (as-is basis) = -236 + (46.08 x % of glycerin) + (61.78 x % of methanol

    Aim: To study the effects of patient variability, technical examination and radiologist-related factors on the radiological diagnosis of barium enema studies. Materials and Methods: Twenty-one residents (12 women and nine men, age 26-39 years) performed 523 double contrast barium enemas in a university hospital. Diagnoses were classified as normal (n=203), diverticulosis (n=224), polyps (n=25), tumours (n=20) and other (n=46); five were missing diagnoses. Binary and multinomial logistic regressions were used to study the relations between the independent variables and the radiological diagnoses. Results: Patients' advanced age (p<0.001) and obesity (p=0.041) were significant positive predictors for the detection of any abnormalities, as was good or moderate study quality (p=0.023). However, patients' obesity was negatively associated with the detection of polyps (p=0.037). Pathological findings were associated with higher dose-area products (p=0.047) than normal cases. Residents' advanced age (p=0.029) and experience (a high number of previously performed barium enemas; p=0.009) were negative predictors for the detection of pathological findings. Conclusion: Patients' obesity hampers polyp detection, possibly due to decreased image quality or coexisting diverticula. The most experienced and oldest residents missed positive findings, possibly due to insufficient consultation of supervising radiologists, emphasizing the need for their optimal cooperation.

    Full Text Available A review of500 cases was undertaken in order to identify which patients undergoing hrsterectomy for benign disease weresubjected topreoperative intravenous pyelogram (lVP and/ or barium enema (BE, and what abnormalities couldbe anticipatedbythese procedures as a surgical screen."nOver 80% ofthe cases reviewed underwent trans-ahdominal hysteredomy, and the remainder hadvaginal hysterectomy. Close to one-third of the patients were admitted with the diagnosis offibroid; and one-sixth with uterine prolapse. Miscellaneous benign conditions included adnexal masses, ovarian cysts, and dysfunctional uterine bleeding. Twentytwo patients (4.4% had IVP preoperatively, while eight patienls (1.6% were given both lIP and barium enema prior to hysterectomy. Over three-fourth ofthe 22 patients revealed normal IVP, while one-half who had received both IVP and/or BE had an unremarkable roentgenogram interpretation. None of the subiects who had unusual findings in either group were ofclinical significance on the pathology report Post-operative coursefor the patients was also quite unremarkable. This review indicates that when benign disease is clear-cut and hysteredomy is indicated there is no needfor IVP and barium enema.

    Crude glycerin, a potential energy source for ruminant animals, has been evaluated, mainly, in diets with high starch content. However, a limit number of studies have evaluated the inclusion of crude glycerin in low starch diets. This study aimed to evaluate the effects of the association of crude glycerin with corn grain or citrus pulp on carcass traits and meat quality of Nellore bulls (n=30, 402±31 kg initial weight). The treatment consisted of: CON=control, without crude glycerin; CG10=10% of crude glycerin and corn grain; CG15=15% of crude glycerin and corn grain; CP10=10% of crude glycerin and citrus pulp; CP15=15% of crude glycerin and citrus pulp. The performance parameters and carcass traits were not affected by treatments (P>0.05). The inclusion of crude glycerin decreased yellow color intensity and increased fatty acids pentadecanoic and heptadecenoic in meat (Pglycerin with corn or citrus pulp has no adverse effects on carcass characteristics and meat quality.

    Pickett, Derek Kyle

    Due to an increased interest in sustainable energy, biodiesel has become much more widely used in the last several years. Glycerin, one major waste component in biodiesel production, can be converted into a hydrogen rich synthesis gas to be used in an engine generator to recover energy from the biodiesel production process. This thesis contains information detailing the production, testing, and analysis of a unique synthesis generator rig at the University of Kansas. Chapter 2 gives a complete background of all major components, as well as how they are operated. In addition to component descriptions, methods for operating the system on pure propane, reformed propane, reformed glycerin along with the methodology of data acquisition is described. This chapter will serve as a complete operating manual for future students to continue research on the project. Chapter 3 details the literature review that was completed to better understand fuel reforming of propane and glycerin. This chapter also describes the numerical model produced to estimate the species produced during reformation activities. The model was applied to propane reformation in a proof of concept and calibration test before moving to glycerin reformation and its subsequent combustion. Chapter 4 first describes the efforts to apply the numerical model to glycerin using the calibration tools from propane reformation. It then discusses catalytic material preparation and glycerin reformation tests. Gas chromatography analysis of the reformer effluent was completed to compare to theoretical values from the numerical model. Finally, combustion of reformed glycerin was completed for power generation. Tests were completed to compare emissions from syngas combustion and propane combustion.

    Full Text Available OBJECTIVE: The aim of the study was to determine which was the optimal side for the conduit to be placed (right or left colon for antegrade continence enema implantation. MATERIALS AND METHODS: Between July 1999 and March 2006, 31 patients underwent the construction of a catheterizable conduit using the Malone principle (MACE In 22 cases the conduit was re-implanted in the right colon and in 9 cases in the left colon. There were 20 male patients and 11 female patients, with a mean age of 10.23 years. The follow-up period varied from 3 from 83 months (average 25 months. Right and left implantation of the conduit in the colon were compared with regards to the presence of complications, volume of the solution utilized, frequency of colonic lavage, time needed for performing the enema, and degree of satisfaction. RESULTS: One patient with the conduit in the right colon, using the appendix, lost the mechanism after two month follow-up. Thirty patients remain clean and are all capable of performing self-catheterization. No statistically significant differences were found between the groups regarding the variables studied: complications (p = 1.000, solution volume (p = 0.996, time required (p = 0.790 and patient's rating (p = 0.670. The lavage frequency required for patients with the conduit in the right colon may be lower. CONCLUSION: The MACE principle was considered effective for treating fecal retention and leaks, independent of the implantation site. The success of this surgery appears to be directly related to the patient's motivation and not to the technique utilized.

    Full Text Available An effective preservation method and decreased rejection are essential for tracheal transplantation in the reconstruction of large airway defects. Our objective in the present study was to evaluate the antigenic properties of glycerin-preserved tracheal segments. Sixty-one tracheal segments (2.4 to 3.1 cm were divided into three groups: autograft (N = 21, fresh allograft (N = 18 and glycerin-preserved allograft (N = 22. Two segments from different groups were implanted into the greater omentum of dogs (N = 31. After 28 days, the segments were harvested and analyzed for mononuclear infiltration score and for the presence of respiratory epithelium. The fresh allograft group presented the highest score for mononuclear infiltration (1.78 ± 0.43, P <= 0.001 when compared to the autograft and glycerin-preserved allograft groups. In contrast to the regenerated epithelium observed in autograft segments, all fresh allografts and glycerin-preserved allografts had desquamation of the respiratory mucosa. The low antigenicity observed in glycerin segments was probably the result of denudation of the respiratory epithelium and perhaps due to the decrease of major histocompatibility complex class II antigens.

    Full Text Available ABSTRACT The objective of this study was to assess the effects of including crude glycerin in the diet on intake, performance, rumen development, and carcass traits of dairy crossbred veal calves fed starter concentrate containing 0, 80, 160, and 240 g kg−1 crude glycerin. Twenty-eight calves with an average weight of 38.03±6.7 kg and five days of age were distributed in a completely randomized design with four treatments with seven replications. Calves were individually housed in covered stalls equipped with feeders and drinkers for 56 days. The calf response to inclusion of crude glycerin in the concentrate changed over the weeks and the inclusion level of 240 g kg−1 resulted in greater dry matter intake and average daily gain. There was no effect on the final weight and total weight gain of the animals, with mean values of 73.60 and 35.16 kg, respectively. The weight of the rumen-reticulum adjusted for body weight, empty body weight, and total stomach weight increased linearly with the inclusion of crude glycerin. Blood total protein, globulin, urea, cholesterol, gamma glutamyl transferase, aspartate aminotransferase, and alkaline phosphatase concentrations did not differ among treatments. Carcass traits and meat color were not affected. Crude glycerin can be added to dairy calf starter concentrate up to 240 g kg−1 dry matter because it benefits concentrate intake, performance, and rumen development without affecting animal health.

    The aims of this study were to simplify the fermentation medium and to optimize the conditions of dark fermentation of residual glycerin to produce biohydrogen. It was possible to remove all micronutrients of fermentation medium and improve biohydrogen production by applying residual glycerin as feedstock. After statistical analysis of the following parameters pH, glycerin concentration and volatile suspended solids, the values of 5.5; 0.5g.L(-1) and 8.7g.L(-1), respectively, were defined as optimum condition for this process. It generated 2.44molH2/molglycerin, an expressive result when compared to previous results reported in literature and considering that theoretical yield of H2 from glycerol in dark fermentation process is 3molH2/molglycerol. This study allowed the improvement of yield and productivity by 68% and 67%, respectively.

    Full Text Available Meniscus alloimplants have been used as a source of tissue for replacement in case of breakage or irreparable damage. To determine possible changes by conservation, the study proposed to geometrically evaluate fresh menisci and menisci preserved in 98% glycerin. 15 medial menisci from eight albino rabbits of New Zealand breed were used, divided into three groups: five fresh menisci (GI; five menisci preserved in 98% glycerin for eight months (GII, and five menisci preserved in 98% glycerin for eight months and then rehydrated in 0.9% saline solution for 24 hours (GIII. All menisci were measured with vernier caliper at seven points of their geometric structure. The study established that there were no statistical differences in the measurements of GII and GIII when compared to GI; there was no difference either in the measurements of GIII when compared to GII, thus rehydration in antibiotic saline solution for 24 hours can be considered unnecessary.

    The objective of this study was to evaluate the effects of crude glycerin on performance and carcass characteristics in finishing wether lambs. Thirty black-faced, Suffolk-cross wether lambs (44.1 +/- 5.6 kg initial BW) were stratified and blocked by BW to 1 of 5 individually fed, isocaloric, isonitrogenous dietary treatments containing 0, 5, 10, 15, or 20% crude glycerin (88% pure) on a DM basis. Diets were fed once daily for ad libitum consumption and contained 15% chopped hay, approximately 25% dried distillers grains with solubles, and the specified treatment combination of cracked corn replaced with increasing amounts of crude glycerin. Wethers were weighed on 14-d intervals and were selected for slaughter when they reached an approximate 12th-rib fat depth of 0.51 cm (28 to 84 d on trial). Carcass characteristics were collected after a 48-h chill. Dry matter intake (linear, P = 0.004) and ADG (quadratic, P = 0.05) increased with increasing concentrations of glycerin in the diet during the first 14 d of the feeding period. Similarly, G:F tended to increase quadratically (P = 0.06) with increasing concentrations of crude glycerin in the diet during the first 14 d. However, there were no differences among treatments for final BW, days on feed, or cumulative DMI, cumulative ADG, and cumulative G:F (P >or= 0.11). Body wall thickness, dressing percent, HCW, LM area, flank streaking, leg score, conformation score, quality grade, yield grade, and percent boneless, closely trimmed retail cuts did not differ (P >or= 0.21). Adding up to 15% crude glycerin to finishing wether diets improved feedlot performance, particularly during the first 14 d, without any concomitant effect on carcass characteristics.

    Full Text Available ABSTRACT: The increasing availability of crude glycerin from biodiesel production has generated great stock in the industries. To solve this problem, crude glycerin is being used as an energy source to replace corn in livestock diets. This study evaluated the effects of the association of crude glycerin (10% on DM of diets with different roughages in Nellore cattle diets on ruminal pH and ammonia, degradability, digestibility of dry matter and nutrients, and greenhouse gas production. Six ruminally cannulated Nellore steers were assigned to a 6×6 Latin square design. The following treatments were evaluated: Hydrolyzed Sugarcane associated or not with crude glycerin, Corn Silage associated or not with crude glycerin or Tifton-85 Hay associated or not with crude glycerin. Association of crude glycerin with roughages did not affect the rumen ammonia concentration and pH and dry matter intake, but reduced the intake of NDF for diets with Hydrolyzed Sugarcane and Corn Silage and reduced the digestibility of DM, OM, NDF, EE, CNF and starch and decreased the effective degradation at the rate of 8% h-1 for diets with Tifton-85 Hay. The association crude glycerin with Hydrolyzed Sugarcane reduced the production of CH4 and CO2 in mL g-1 of DM. The inclusion of crude glycerin affects differently nutrient utilization in diets with Corn Silage, Hydrolyzed Sugarcane or Tifton-85 hay. Moreover, promotes mitigation of greenhouse gases in diets with Hydrolyzed Sugarcane. Association of crude glycerin with Corn Silage in Nellore cattle diets showed better conditions of ruminal fermentation and utilization of nutrients.

    AIM: To attempt rectal administration of rebamipide in the treatment of ischemic colitis patients with ulcers, and evaluate its effects. METHODS: We compared 9 ischemic colitis patients (2 men, 7 women) with ulcers treated by bowel rest only from 2000 to 2005 (conventional therapy group), with 6 patients (2 men, 4 women) treated by rebamipide enema therapy in 2006 (rebamipide enema therapy group) and analyzed the mean duration of fasting and hospitalization, degree of ulcer healing, and decrease in WBC count for the two groups. RESULTS: The mean duration of fasting and hospitalization were 2.7 ± 1.8 d and 9.2 ± 1.5 d in the rebamipide group and 7.9 ± 4.1 d and 17.9 ± 6.8 d in the control group, respectively, and significantly reduced in the rebamipide group (t = -2.915; P = 0.0121 and t = -3.054; P = 0.0092). As for the degree of ulcer healing at 7 d after admission, the ulcer score was reduced by 3.5 ± 0.5 (points) in the rebamipide group and 2.8 ± 0.5 (points) in the control group (t = 1.975; P = 0.0797), while the decrease in WBC count was 120.0 ± 55.8 (× 102/μL) in the rebamipide group and 85.9 ± 56.8 (× 102/μL) in the control group (t = 1.006; P = 0.3360). CONCLUSION: In left-sided ischemic colitis patients with ulcers, rebamipide enema therapy significantly reduced the duration of fasting and hospitalization, recommending its use as a new and effective therapeutic alternative.

    Background The few studies on MR colonography with air enema involved feasibility of bowel distention and imaging quality and lacked detection sensitivity of colorectal neoplasms. The purpose of this prospective study was to assess the detection sensitivity of colorectal neoplasms with the three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema.Methods A total of 30 patients scheduled for optical colonoscopy due to rectal bleeding, positive fecal occult blood test results or altered bowel habits were recruited and successfully underwent entire colorectal examinations with three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography and subsequent optical colonoscopy on the same day. Detection sensitivity of colorectal neoplasms with MR colonography was statistically analyzed on a per-neoplasm size basis by using findings from optical colonoscopy and histopathological examinations as the reference standards.Results Seventy-six neoplasms were detected with optical colonoscopy, consisting of 1 mm-5 mm (n=11), 6 mm-9 mm (n=29) and >10 mm (n=36) in diameter. Detection sensitivities of 1 mm-5 mm, 6 mm-9 mm, ≥10 mm and >6 mm colorectal neoplasms with MR colonography were 9.1%, 75.9%, 100% and 89.2%, respectively; overall detection sensitivity for all sizes colorectal neoplasms was 77.6%.Conclusions Detection sensitivity of three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema is low for 1 mm-5 mm colorectal neoplasms, but the detection sensitivity is 89.2% for ≥6 mm neoplasms, and all ≥10 mm neoplasms could be detected.

    Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmonary embolism, was administered an enema resulting in severe abdominal pain unresponsive to blood transfusion. A sigmoid colectomy with end colostomy was performed. Although rare, colonic and recto-sigmoid hematomas should be considered as a possible diagnosis for adults with abdominal pain on anticoagulant therapy. PMID:28108634

    1986-11-01

    A 19-year old female with a bloody, diarrheal illness of acute onset where Crohn's disease primarly was suspected is presented. The double-contrast barium enema revealed multiple, diffusely scattered aphthous erosions of the colonic mucosa: the rectum was scarcely affected. Biopsies taken by endoscopy demonstrated nonspecific inflammatory changes of the mucous membrane. However, routinely taken stool cultures revealed an infectious colitis due to Yersinia enterocolitica. Our case demonstrates the necessity to consider Yersinia enterocolitis in the radiographic differential diagnosis when the diagnosis of Crohn's disease or ulcerative colitis seems obvious.

    During transesterification of vegetable oils in particular, but also animal fats and used frying oils, glycerine is obtained as a by-product. It is important for transesterification economics that the glycerine by-product can be sold for the best possible price. In Sweden today, glycerine is often sold to biogas production for a few Swedish crowns per kilo. If other markets where glycerine replaces a more expensive product can be found, the willingness to pay for glycerine will increase. This project examined whether glycerine can be used as an additive in pelleting some biofuel types, and the value it would have in this use. The project investigated admixtures of appropriate amounts of glycerine of varying quality during pelleting of some types of fuel (straw, reed canary grass and pine wood). To determine how these affect pellet quality, the function of the pellet press, pellet storage properties, the risk of harmful emission levels of carbon monoxide (CO), nitrogen oxides (NO{sub x}), sulphur oxides (SO{sub 2}) and aldehydes during incineration of the pellets, the risk of ash sintering and the risk of corrosive deposits in flue gas channels were examined. In addition, the commercial value of the glycerine when added to pellets was estimated. Pelleting trials were conducted using 1 % and 5 % admixtures of four types of glycerine in three types of fuel. Two of the glycerine products were alkaline, originating from alkaline transesterification of rapeseed oil, and two were acidic, originating from acid esterification/ transesterification followed by alkaline transesterification, of rapeseed oil in one case and used frying oil in the other. The fuel types were pine wood, reed canary grass and straw. After pelleting, pellet durability, the amount of fine fraction and bulk density were measured. Chemical analyses were performed of glycerine types, fuel types and glycerine/fuel mixtures to evaluate ash melting behaviour and the risk of corrosion associated with alkali

    Full Text Available The objective of this study was to evaluate the nutritional and productive characteristics of primiparous lactating cows grazing on tropical pasture, using different levels of crude glycerin in the supplement. The experiment was conducted at Rancho Santana farm, located in Jequié city, Bahia, Brazil, in the period from December 21, 2010 to March 16, 2011. Ten ¾ Holstein × ¼ Dairy Gyr lactating primiparous cows, with 109±24 days of lactation and a mean age of 30±6 months and mean body weight of 426.2±68.29 kg were distributed into five treatments, using two simultaneous 5 × 5 latin squares. Treatments consisted of inclusion levels (0, 94, 191, 289, 389 g/kg dry matter basis of crude glycerin in the supplement. Intake, digestibility, milk production and composition were measured. Results were statistically analyzed by analysis of variance and regression at 0.05 probability. For all consumption variables no significant differences were found between the levels of crude glycerin. Except for the digestibility of ether extract, all digestibility values were similar between treatments. The fat content and yield showed quadratic effect between treatments. No significant differences were observed for protein, lactose, total solids, nonfat dry extract, fat:protein ratio, milk urea nitrogen and somatic cell count between treatments. For primiparous lactating cows grazing on tropical pasture, up to 389 g of crude glycerin/kg of dietary supplement can be included without nutritional and productive interference.

    Surface Plasmon Resonance (SPR) based on Mach-Zehnder interferometer (MZI) is a very accurate tool for the detection and analysis of molecular interactions. The performance of the proposed SPR phase sensor is dependent upon multiple performance parameters that include sensitivity, repeatability, drift and the induction speed of fluid into the flow cell. The SPR Mach-Zehnder interferometer is tested for different glycerin-water concentrations to check its performance based on the different parameters. This paper highlights the enhancement of the performance of SPR phase technique based on MZI that is influenced by different parameters, measured using glycerin solutions. These four performance parameters can affect the performance of SPR based on MZI and have a particular impact on the sensor output. It also provides us information about suitable working conditions for the SPR Mach-Zehnder interferometer sensor. The experiment data shows that the sensor's sensitivity is high for small concentrations of glycerin-water mixtures. Also, any change in drift as well as in induction speed of fluid can affect the performance of SPR Mach-Zehnder interferometer. The sensitivity of SPR phase sensor is high as it can measure glycerin concentration as low as 0.05%.

    Full Text Available The production and rheological properties of xanthan gum from crude glycerin fermentation, a primary by-product of the biodiesel industry with environmental and health risks, were evaluated. Batch fermentations (28 °C/250 rpm /120 h were carried out using crude glycerin, 0.01% urea and 0.1% KH2PO4, (% w/v, and compared to a sucrose control under the same operational conditions, using Xanthomonas campestris strain 2103 isolate from Brazil. Its maximal production by crude glycerin fermentation was 7.23±0.1 g·L-1 at 120 h, with an apparent viscosity of 642.57 mPa·s, (2 % w/v, 25 °C, 25 s-1, 70% and 30% higher than from sucrose fermentation, respectively. Its molecular weight varied from 28.2 to 36.2×10(6 Da. The Ostwald-de-Waele model parameters (K and n indicated a pseudoplastic behavior at all concentrations (0.5 to 2.0 %, w/v and temperatures (25-85 °C, while its consistency index indicated promising rheological properties for drilling fluid applications. Therefore, crude glycerin has potential as a cost-effective and alternative substrate for non-food grade xanthan production.

    Full Text Available ABSTRACT The medium for storing biological tissues is of great importance for their optimal use in surgery. Glycerin has been proven efficient for storing diverse tissues for prolonged time, but the preservation of the bovine amniotic membrane in glycerin 99% at room temperature has never been evaluated to be used safely in surgical procedures. This study evaluated the preservation of 80 bovine amniotic membrane samples stored in glycerin 99% at room temperature. The samples were randomly divided evenly into four groups. Samples were microbiologically tested after 1, 6, 12 and 48 months of storage. The presence of bacteria and fungi in the samples was evaluated by inoculation on blood agar and incubation at 37 ºC for 48 hours and on Sabouraud agar at 25 ºC for 5 to 10 days. No fungal or bacterial growth was detected in any of the samples. It was concluded that glycerin is an efficient medium, regarding microbiology, for preserving pre-prepared bovine amniotic membrane, keeping the tissue free of microorganisms that grow in the media up to 48 months at room temperature.

    Full Text Available Current research studied the effect of partial replacing corn by glycerin and essential oils addition in the diet of Nellore bulls finished in feedlot on feed intake, animal performance and three markers were assessed to estimate apparent digestibility. Thirty bulls with average weight 400 ± 34.1 kg and 22 ± 2 months old were housed in collective pens (10 x 20 m2 for 63 days. The bulls were randomly assigned to 3 diets (10 bulls per treatment: CON – Control (without glycerin or Essential® oils; GLY – Glycerin (15% on dry matter - DM; and GEO – Glycerin (15% on DM and Essential® oils (3 g animal day-1. Three different markers were used to estimate apparent digestibility in the diets: indigestible dry matter –iDM; indigestible neutral detergent fiber – iNDF; and purified lignin – LIPE®. Feed efficiency and animal performance were not affected by the corn partial replacing by glycerin. No effects were found in partial corn replacing by glycerin and Essential® oils addition in the diets on the fecal output, crude protein and ether extract digestibility among the diets. The DM and OM apparent digestibility were higher for bulls fed with glycerin and Essential® oils. The CHO digestibility was higher for CON diet. The markers iDM, iNDF and LIPE® were similarly to estimate apparent digestibility to all nutrients in the diets.

    Kanki demonstrated a high prevalence and frequency of enema practised with newborns in the South-West of Burkina Faso. Little is known about the risks on children's health possibly associated with this practice and about its impact on other treatments in paediatrics. In this study, the authors describe daily administered enema (DAE) and analyse local conceptual frameworks underlying this practice through in-depth-interviews and focus group discussions with 30 mothers, 5 traditional healers and 5 health agents. Various medications are used to compose the liquid introduced by the mothers in the child's anus. Many of these substances are prone to irritate intestinal mucus, others are simply toxic. Practically, enema aims at curing or preventing a variety of diseases caused by an accumulation of impurities (nògò) in the intestines due to the consumption of inappropriate food. With newborns, diseases are transmitted by mothers through breastfeeding after eating food which is too sweet or too fat. In addition to provoking diseases, the nògò also "block" the child's physical and psychic development during his/her first year of life. Therefore, as soon as the child has excreted for the first time, most mothers give enema daily both to protect their children from diseases and to speed their development. In fact, beside prophylaxy and therapy lies a "didactic" function of enema as a medication used to help the child to stand up, to get teeth..., to gain independence from his/her mother. DAE therefore plays an important role in the process of acquiring bio-social aptitudes, i.e., important educational virtues to achieve a successful first step in the socialisation process. Exploring more deeply local perceptions explaining the origin of the n g , the authors found an interesting relationship with religious taboos. Beside prohibited food, the n g are also due to transgression of various taboos surrounding birth and breastfeeding and even suggest a religious, rather than

    An anaerobic sequencing batch biofilm reactor (AnSBBR) with recirculation of the liquid phase (at 30 °C with 3.5 L of working volume and treating 1.5 L per cycle) treating pure glycerin-based wastewater was applied to biohydrogen production. The applied volumetric organic load (AVOL) ranged from 7.7 to 17.1 kgCOD m(-3) d(-1), combining different influent concentrations (3000, 4000 and 5000 mgCOD L(-1)) and cycle lengths (4 and 3 h). The feed strategy used was to maintain the feeding time equal to half of the cycle time. The increase in the influent concentration and the decrease in cycle length improved the molar yield and molar productivity of hydrogen. The highest productivity (100.8 molH2 m(-3) d(-1)) and highest yield of hydrogen per load removed (20.0 molH2 kgCOD(-1)) were reached when the reactor operated with an AVOL of 17.1 kgCOD m(-3) d(-1), with 68% of H2 and only 3% of CH4 in its biogas. It was also found that pretreatment of the sludge/inoculum does not influence the productivity/yield of the process and the use of crude industrial glycerin-based wastewater in relation to the pure glycerol-based wastewater substantially decreased the production and composition of the hydrogen produced.

    Effects of feeding a dry glycerin product (minimal 65% of food grade glycerol, dry powder) to 39 multiparous Holstein dairy cows (19 control and 20 glycerin-supplemented; lactation number = 2.2 +/- 1.3 SD) on feed intake, milk yield and composition, and blood metabolic profiles were investigated. Dry glycerin was fed at 250 g/d as a top dressing (corresponding to 162.5 g of glycerol/d) to the common lactating total mixed ration from parturition to 21 d postpartum. Individual milk was sampled from 2 consecutive milkings weekly and analyzed for components. Blood was sampled from the coccygeal vein at 4, 7, 14, and 21 (+/-0.92, pooled SD) d in milk and analyzed for urea nitrogen, glucose, insulin, nonesterified fatty acids, and beta-hydroxybutyrate. Urine was tested for the acetoacetate level weekly by using Ketostix. Average feed intake, milk yield and components, blood metabolites, and serum insulin concentrations were not affected by dry glycerin supplementation. Glycerin-supplemented cows experienced a more positive energy status (higher concentrations of plasma glucose, lower concentrations of plasma beta-hydroxybutyrate, and lower concentrations of urine ketones), which was observed during the second week of lactation, suggesting that energy availability may have been improved. This glucogenic effect of dry glycerin did not result in an increase in feed intake or milk yield during the first 3 wk of lactation, likely because of the relatively less negative energy status of cows transitioning into lactation. The tendency toward higher milk yield for glycerin-supplemented cows during wk 6 of lactation (52 vs. 46 kg/d) after the supplementation period (dry glycerin was terminated at wk 3 of lactation) suggested a potential benefit of dry glycerin on subsequent milk production, perhaps through changes in metabolism, which requires further investigation.

    Full Text Available The current study aims to assess the effect from crude glycerin inclusion (0, 7, 14, and 21% dry matter in the diet of slaughtered lamb on their development, nutrient consumption, biometrical measures, diet economic viability and carcass features. Thirty two (32 non-castrated male Texel lambs were used in the study, they presented mean initial weight 15.9 ± 4.1 kilos and were distributed in casual outlining. They were fed with four treatments, with 8 repetitions. Animals were slaughtered when they reached approximately 35 kilos. The mean total weight gain was 20.72 kilos and mean daily weight gain was 260 grams. No changes resulted from glycerin use. The carcass performance was similar among treatments (P>0.05 and the cold carcass performance (CCP was 44.68%. There were no effects (P>0.05 on the loin eye area (LEA and on fat thickness (FT; they showed averages of 13.66 cm2 and 0.84 mm, respectively. Nutrition cost per animal during the whole confinement period varied between R$82.60 (eighty-two Reais and forty-eight cents to R$92.48. The smallest nutrition amount consisted of 21% crude glycerin. The gross profit ranged from R$30.75 to R$ 34.01 per animal, for feed without glycerin and 21% glycerin, respectively. Animal development was not impacted by glycerin introduction, even with decrease on dry and organic mass consumption. The result showed that crude glycerin inclusion might be used in lambs’ diet. Whenever there are big amounts of feed involved in the process, the 21% crude glycerin addition may be an interesting cost reduction. Seventy eight percent (78% glycerol crude glycerin to replace corn-based feed in confined lambs’ diet appeared to be nutritionally and economically viable.

    2010-01-01

    Full Text Available Glycerin is a by-product obtained during the biodiesel manufacture, through the transesterification reaction of vegetal oils. The prevision of excedent glycerine in the next few years, due to the increasing of the biodiesel production in Brazil, has been generating a discussion about new applications to this by-product. This article presents a theoretical study about the possible synthesis of a new flocculant agent, from semi-refined glycerine and p-nitrobenzoic acid to produce a quaternary ammonium salt, to be used in water treatment. The reactions which would occur during the synthesis of the flocculant agent and the necessary tests to the product validation are presented.

    Full Text Available Avaliou-se o efeito de diferentes soluções de enema sobre os parâmetros clínicos de eqüinos hígidos. Foram utilizados 15 eqüinos adultos, distribuídos em três grupos de cinco animais cada: grupo 1 - tratados com água de torneira mais sabão neutro; grupo 2 - tratados com solução isotônica e grupo 3 - tratados com água de torneira mais vaselina. O efeito das soluções de enema sobre os parâmetros clínicos variou em função do tipo de solução infundida. A solução com menor efeito sobre os parâmetros clínicos foi a isotônica. A solução de água de torneira e sabão neutro desencadeou um aumento da temperatura retal e edema da mucosa retal. Embora as três soluções tenham se mostrado efetivas em hidratar e amolecer as fezes, a solução de água com sabão foi a que apresentou o melhor efeito.The effect of three different enema solutions on clinical parameters of equines was studied using 15 healthy adult animals. They were alloted into three groups of five animals each: group 1 - treated with tap water associated with neuter soap; group 2 -treated with isotonic solution; and group 3 - treated with tap water associated with vaseline. Effects of enema solutions on clinical parameters were observed. Isotonic solution caused less alteration on clinical parameters. Tap water and soap enema induced inflammatory reaction on colon mucosa. Even though all three solutions showed effectiveness in hydrating and softening the feces, the treatment with water plus soap showed the best results.

    The presence of stools in the rectum might affect the quality of the abdominal pressure curve during filling cystometry, but, to date, no study has evaluated the impact of bowel preparation before urodynamics. We evaluated the influence of a sodium phosphate enema before urodynamics on the quality of the abdominal pressure curve. A prospective, controlled, single-blind study was conducted in a single center from May to June 2013. The patients were divided into 2 consecutive groups: patients seen in outpatient clinics during the first 6 weeks (group A) who underwent urodynamics without bowel preparation and patients seen in outpatient clinics during the second 6 weeks (group B) who had a prescription of sodium phosphate enema before urodynamics. The primary endpoint was the quality of the abdominal pressure curve evaluated independently by three physicians who were blinded to the study group. The following data were also collected: age, gender, the presence of a neurological disorder, complicated nature of urodynamics and bother related to preparation for it, assessed using a Likert scale (0 to 10), and the equipment used. A per protocol analysis and an intent-to-treat analysis were conducted. One hundred and thirty-nine patients were included: 54 in group A and 85 in group B. One-third of patients had neurological conditions. 14 patients in group B did not perform their scheduled enema. Thus, 68 patients performed an enema before urodynamics and 71 did not. There was no difference between groups A and B regarding the complicated nature of urodynamics (Likert scale: 3.12 vs. 3.18; P=0.91) or bother related to preparation for it (Likert scale: 3.46 vs. 2.97; P=0.43). In the per protocol analysis, the abdominal pressure curve was considered perfectly interpretable (PI) in 69% of patients who did not receive an enema before urodynamics and in 65% of patients who did (P=0.61). The between-group difference was not statistically significant in intent-to-treat analysis (P

    To examine the effectiveness of screening proctosigmoidoscopy, barium enema radiography, and the fecal occult blood test (FOBT) in decreasing colorectal cancer mortality in a community setting. In this population-based case-control study, cases comprised 218 Rochester, Minn, residents who died of colorectal cancer between 1970 and 1993. Controls were 435 age- and sex-matched residents who did not have a diagnosis of colorectal cancer. Screening proctosigmoidoscopy, barium enema radiography, and FOBT results were documented for the 10 years prior to and including the date of diagnosis of fatal colorectal cancer in cases and for the same period in matched controls. History of general medical examinations and hospitalizations was also recorded. Within the 10 years prior to diagnosis, the percentages of cases vs controls with at least 1 screening proctosigmoidoscopy were 23 (10.6%) of 218 cases vs 43 (9.9%) of 435 controls; at least 1 screening barium enema radiographic study was done in 12 (5.5%) of 218 vs 25 (5.7%) of 435. Within 3 years prior to diagnosis, the percentages of cases vs controls with at least 1 screening FOBT were 27 (12.4%) of 218 vs 44 (10.1%) of 435. Adjusted odds ratios were 1.04 (95% confidence interval [CI], 0.21-5.13) for proctosigmoidoscopy (distal rectosigmoid cancers only), 0.67 (95% CI, 0.31-1.48) for barium enema radiography, and 0.83 (95% CI, 0.45-1.52) for FOBT over the above time periods. In this case-control study within a community setting, a colorectal cancer-specific mortality benefit could not be demonstrated for screening by FOBT, proctosigmoidoscopy, or barium enema radiography. Screening frequency was low, which may have contributed to the lack of measurable effects.

    Early full enteral feeding in preterm infants decreases morbidity and mortality. Our systematic review covered the effectiveness of rectal stimulation, suppositories and enemas on stooling patterns and feeding tolerance in low-birthweight infants born at up to 32 weeks. It comprised seven studies published between 2007 and 2014 and covered 495 infants. Suppositories were ineffective in shortening the time to reach full enteral feeding, and the evidence on enemas was contradictory. Enemas and rectal stimulation did not shorten the time until complete meconium evacuation was reached. Further research into safe, effective interventions to accelerate meconium excretion is needed. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    The increasing availability of crude glycerin from the biodiesel industry has led to an interest in its use as an energy source in ruminant diets. However, its effects on ruminal fermentation patterns and methane (CH4) production are unclear, and there are no reports on the effect of its inclusion in the diet on wool production or growth of Merino sheep. Thus, the objectives of this study were to determine the effects of increasing levels of crude glycerin on in vitro ruminal fermentation and CH4 production and DMI, BW, feeding behavior, and wool growth and quality in Merino ewes. Crude glycerin (99.2% pure, colorless, odorless, viscous liquid) replaced whole wheat grain in completely pelleted diets at levels of 0%, 6%, and 12% DM in both in vitro and in vivo studies. For in vitro studies, diets were dried and ground through a 1-mm screen and incubated on 2 different days for 24 h. Modified McDougal's buffer and rumen liquor were mixed 3:1, and gas production and CH4 concentration was measured after 6, 12, and 24 h of incubation with pH and IVDMD measured at 24 h. Cumulative gas (mL/g DM) and methane (mL) production was similar (P ≥ 0.35) among dietary treatments. In vitro dry matter disappearance (%) increased (P glycerin. For the in vivo study, 39 Merino ewes were randomly assigned to 3 treatments (n = 13 ewes/treatment). Pelleted diets were available continuously for a 10-wk period through the use of automatic feeders. Ewes were weighed every 7 d. Wool yield was determined on mid-side patches of 100 cm(2) shorn at d 0 and d 70. Dye bands were used to determine wool growth and fiber length. Intake and ADG were similar among treatments (P = 0.59). Neither wool yield, length, spinning fineness, nor fiber diameter (μm) were affected after supplementation with crude glycerin (P ≥ 0.13). This study indicates the potential for crude glycerin to be included in the diets of Merino sheep at up to 12% DM without negatively affecting wool yield and quality.

    The objective of this study was to determine the apparent metabolisable energy corrected for nitrogen balance (AMEn) of some products containing glycerine from soybean oil (GOIL), a mixture of frying oil and lard (GMIX) and a semi-purified process (GSP) in broilers of different ages (10, 20, 30 and 40 days post-hatching), using two methodologies. In trial 1, the basal diets were replaced with 100 g/kg of each studied glycerine product and the diets were supplied ad libitum. Three hundred broilers were used in five replicates, with five, four, three and three animals per cage in each age group, respectively. The AMEn was calculated for each experimental unit. In trial 2, dietary treatments included the addition of glycerine at 0, 40, 80 or 120 g/kg for each crude glycerine product, with 900 broilers in six replicates, using the same number of animals per cage as described in trial 1. Depending on the experimental unit, the feeding was restricted in 88%, 92%, 96% and 100% of estimated intake according to the Cobb guide. The AMEn was determined using linear regression between the feed intake and the AMEn of each diet. In both trials, the total excreta collection method was used. Because of the chemical composition, GMIX was not considered crude glycerine. The mean AMEn values of the products were 20.55 MJ/kg, 15.80 MJ/kg and 15.05 MJ/kg for GMIX, GSP and GOIL, respectively. There was a linear decrease (p values with the increasing age of the broilers. Numerically, it was observed that the AMEn values decreased until 28-30 day post-hatching and then remained constant until the finishing phase. It is concluded that products containing glycerine can be used as an energy source for broilers, but that AMEn values can vary according to age. Younger broilers have a higher capacity of energy utilisation from these feedstuffs.

    The continued growth in biofuel production has led to a search for alternative value-added applications of its main by-product, crude glycerin. The surplus glycerin production and a higher cost of feedstuffs have increased the emphasis on evaluating its nutritive value for animal feeding. The aim of this research was to evaluate the effect of the dietary addition of crude glycerin on sow and litter performance, and to determine the serum concentrations of hormones related to energy metabolism and feed intake in sows during gestation and lactation. A total of 63 sows were assigned randomly to one of three dietary treatments, containing 0, 3 or 6% crude glycerin (G0, G3 and G6, respectively) added to a barley-soybean meal-based diet. During gestation, none of the dietary treatments had an effect on performance, while during lactation, glycerin-fed sows consumed less feed than those fed the control diet (3.8 v. 4.2kg DM/day; P=0.007). Although lactating sows fed the G3 diet had a higher BW loss than those fed the control diet (���20.6 v. ���8.7 kg; P=0.002), this difference was not reflected in litter performance. In gestation, the inclusion of glycerin did not affect blood concentrations of insulin or cortisol. However, pregnant sows fed diets supplemented with glycerin showed lower concentrations of acyl-ghrelin and higher concentrations of leptin (���55 and +68%, respectively; Pglycerin did not affect the performance of sows during the gestation period; however it had a negative effect on the feed intake and weight loss of lactating sows. Moreover, further research is needed to elucidate the potential relationship between glycerin inclusion levels in the diet and the serum concentrations of hormones related to feed intake and energy balance control.

    To investigate the curative effect and mechanism of using Cassia angustifolia extract (CAE) in treating gastrointestinal tract dysfunction after abdominal operations. Enema administration of CAE (Clyster method) was used. The result of 130 patients was very effective in reducing the rate of gastrointestinal decompression, accelerating the restitution of borborygmi and the time of exhaustion. Animal experiment showed the CAE function is very obvious in enhancing the bowel movement of rats (P < 0.05). It can enhance peristalsis and contraction amplitude of vibration in the isolated ileum of rats (P < 0.05). It can push on the charcoal powder in intestinal tract of mice obviously (P < 0.05). CAE could regulate disordered function of gastrointestinal tract after abdominal operations.

    Glycerine (a biodiesel co-product) and levulinic acid (a pulp and paper co-product) were used as co-substrates for the fermentative synthesis of short-chain polyhydroxyalkanoate (sc-PHA) biopolymers with tunable monomer and molecular weight characteristics. Pseudomonas oleovorans NRRL B-14682 utilized glycerine alone to produce poly(3-hydroxybutyrate) (PHB). When levulinic acid was added to the media at shake-flask scale in concentrations ≤0.6 wt.%, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHB/V) copolymers were produced with 3-HV contents ranging from 37 to 97 mol%; a glycerine:levulinic acid ratio of 0.2%:0.8% (w/v) resulted in poly(3-hydroxyvalerate) (PHV). Ten-liter batch fermentations using glycerine:levulinic acid ratios of 1%:0, 0.75%:0.25%, 0.5%:0.5% and 0.25%:0.75% (w/v) resulted in PHB, P(73%-3HB-co-27%-3HV), P(30%-3HB-co-70%-3HV) and PHV with increasing number average molecular weights (×10(3) g/mol) of 328, 511, 728 and 1330, respectively, owing to glycerine-based chain termination. These results provide a novel means by which glycerine and levulinic acid can be used collectively to produce an array of distinct sc-PHA biopolymers.

    In this study, we evaluated the effects of total corn replacement with crude glycerin on carcass characteristics and meat quality of feedlot lambs fed high-concentrate diets with low starch. Forty non-castrated Santa Ines lambs (23.5 ± 3.56 kg BW) were assigned to a randomized complete block design with five dietary treatments: 0%, 7.5%, 15%, 22.5%, or 30% crude glycerin, replacing corn. Animals were slaughtered at a BW of 38 kg after 72 ± 20 days. The addition of up to 30% crude glycerin reduced carcass weight and yield (P ≤ 0.02). Odd-chain fatty acids, oleic, palmitoleic, total unsaturated, and monounsaturated fatty acids were increased (P ≤ 0.01) while CLA tended to increase in glycerin-fed lambs (P = 0.06). Crude glycerin decreased stearic, palmitic, transvaccenic, total saturated fatty acids, and atherogenicity index (P glycerin in low-starch diets reduced carcass weights, nevertheless improved meat quality by increasing unsaturated and odd-chain fatty acid contents.

    Anaerobic digestion of manure is a widely accepted technology for energy production. However, only a minimal portion of the manure production in the EU is anaerobically digested and occurs predominantly in codigestion plants. There is substantial potential for biogas plants that primarily operate on manure (>90%); however, the methane yields of manure are less compared to coproducts, which is one of the reasons for manure-based biogas plants often being economically non-viable. Therefore, it is essential to begin increasing the efficiency of these biogas plants. This study investigated the effect of decreasing retention time and introducing a moderate amount of glycerin on the biogas production as methods to improve efficiency. An experiment has been conducted with two different manure types in four biogas reactors. The results of the study demonstrated that, first, it was possible to decrease the retention time to 10-15 days; however, the effect on biogas production varied per manure type. Secondly, the biogas production almost triples at a retention time of 15.6 days with an addition of 4% glycerin. The relative production-enhancing effect of glycerin did not vary significantly with both manure types. However, the absolute production-enhancing effect of glycerin differed per manure type since the biogas production per gram VS differed per manure type. Thirdly, the positive effect of the glycerin input declines with shorter retention times. Therefore, the effect of glycerin addition depends on the manure type and retention time.

    Biogas production by co-digestion of cattle manure with crude glycerin obtained from biodiesel production was studied after pre-treatment of the cattle manure or mixtures of cattle manure with different amounts of added glycerin with ultrasound. Batch experiments with 1,750 mL of medium containing 1,760 g of screened cattle manure or mixtures of cattle manure (screened or ground) and 70-140 mL or crude glycerin were incubated under mesophilic and thermophilic condition in stirred tank reactors. Under mesophilic conditions, the addition of 4% glycerin to screened manure increased biogas production by up to 400%. Application of sonication (20 kHz, 0.1 kW, and 4 min) to a mixture of manure+4% glycerin increased production of biogas by up to 800% compared to untreated manure. The best results were obtained under thermophilic conditions using sonicated mixtures of ground cattle manure with 6% added glycerin (348 L methane/kg COD removed were obtained).

    Full Text Available The current study presents a packed column gas chromatographic technique for the estimation of glycerin using a flame ionization detector from a marketed hair tonic in presence of resorcinol, ethanol, biotin, keratin hydrolysate, undecylenic acid alkylolamide (hyalkyl HBU, D-biotin, nicotinic acid, and polyvinylpyrrolidone. The validation studies show the proposed method to be specific, sensitive, precise, and accurate. The method is found to be linear in the concentration range 1.25 mg/mL to 10.02 mg/mL with r2 value 0.99. The limit of detection and the limit of quantitation were 0.01 mg/mL and 0.05 mg/mL, respectively. The method does not involve any complex sample preparation procedure and is therefore suitable for regular analysis of glycerin from marketed hair tonic.

    Soil microcosms were constructed and monitored to evaluate the impact of substrate addition and transient aerobic and anaerobic conditions on TNT, RDX and HMX biodegradation in grenade range soils. While TNT was rapidly biodegraded under both aerobic and anaerobic conditions with and without organic substrate, substantial biodegradation of RDX, HMX, and RDX daughter products was not observed under aerobic conditions. However, RDX and HMX were significantly biodegraded under anaerobic conditions, without accumulation of TNT or RDX daughter products (2-ADNT, 4-ADNT, MNX, DNX, and TNX). In separate microcosms containing grenade range soil, glycerin and lignosulfonate addition enhanced oxygen consumption, increasing the consumption rate > 200% compared to untreated soils. Mathematical model simulations indicate that oxygen consumption rates of 5 to 20 g/m3/d can be achieved with reasonable amendment loading rates. These results indicate that glycerin and lignosulfonate can be potentially used to stimulate RDX and HMX biodegradation by increasing oxygen consumption rates in soil.

    This paper reports on the results of a case study of a 19-year-old female who presented to the Oral Medicine clinic with a chief complaint of scaly and peeling lips. The lesions had persisted on her lips for more than 7 years and were refractory to previous treatment. Her physician’s diagnosis was contact dermatitis. We diagnosed this patient as having exfoliative cheilitis (EC). A patch test using the toothpaste containing sodium lauryl sulfate (SLS) was positive and the patient discontinued using it. Instead, she started using a toothpaste not containing SLS. One year after treating her lesions with hydrogen peroxide mouthwash 1% and glycerin borax, a gradual improvement was observed until returning to normal. Glycerin borax was safe, low cost and simple to use in treatment of refractory exfoliative cheilitis. SLS may have been a precipitating factor in EC in this case. PMID:27789914

    This study is to develop a methodology to identify and evaluate the emissions and heat transfer associated to combustion of gross glycerin a by-product of the Brazilian biodiesel manufacture process as alternative energy source. It aims to increase the present knowledge on the matter and to contribute to the improvement of the economic and environmental perspective of biodiesel industry. This methodology was considered to be used for assessment of gross glycerin combustion from three different types of biodiesel (bovine tallow, palm and soy). The procedures for evaluation and quantification of emissions of sulphur and nitrogen oxides, total hydrocarbons, carbon monoxide, carbon dioxide, and acrolein were analyzed, described and standardized. Experimental techniques for mutagenic and toxic effects assessment of gases similarly were analyzed and standardized, as well as the calorific power, the associate heat transfer and fundamentals operational parameters. The methodology was developed, using a full-instrumented flame tube furnace, continuous gas analyzers, a chromatograph, automatic data acquisition systems and other auxiliary equipment. The mutagenic and toxic effects of the study was based on Tradescantia clone KU-20, using chambers of intoxication and biological analytical techniques previously developed and others were specially adapted. The benchmark for the initial set up was based on the performance evaluation of the previous equipment tested with diesel considering its behavior during direct combustion. Finally, the following factors were defined for the combustion of crude glycerin, configurations of equipment types, operational parameters such as air fuel ratio adiabatic temperature and other necessary aspect for successful application of the methodology. The developed and integrated methodology was made available to the concern industry, environmental authorities and researchers as procedures to access the viability of gross glycerin or similar fuels as

    To determine if glycerin suppositories were effective in reducing total duration of phototherapy in premature neonates. We hypothesized that glycerin suppositories would have no effect on phototherapy duration or total serum bilirubin levels. Prospective randomized controlled double-blinded trial. Level IV NICU. Neonates born between 30 weeks, 0 days and 34 weeks, 6 days gestational age who developed physiologic hyperbilirubinemia needing phototherapy. Neonates were randomized to the no-suppository group or to the suppository group. Neonates were randomized to receive glycerin suppositories every 8 hours while under phototherapy or to a sham group. The primary outcome was total hours of phototherapy. Secondary outcomes included peak total serum bilirubin levels, time from start to discontinuation of phototherapy, rate of decline in bilirubin levels, repeat episodes of phototherapy, and number of stools while the neonates received phototherapy. A total of 39 neonates were assigned to the no-suppository group and 40 to the suppository group. Withholding suppositories was not inferior to providing suppositories. The total hours of phototherapy were not longer (i.e., noninferior) among neonates not provided suppositories (61 ± 53 hours) than among those given suppositories (72 ± 49 hours). There were no differences in peak bilirubin levels, rate of bilirubin decline, or repeat episodes of phototherapy. Routine use of glycerin suppositories among preterm neonates who receive phototherapy does not affect bilirubin levels or phototherapy duration.

    We have developed a method of measuring the isometric tension in glycerinated stalks of Vorticella convallaria. Using this method, we measured tension vs. pCa relations in glycerinated V. convallaria stalks. The maximum isometric tension was 4 x 10(-8) N on average. The Hill's parameter, n, which is the number of calcium ions bound simultaneously and cooperatively to a contractile element (a force generating element), is approximately 3.2 when the Ca2+ concentration is increased and 2.5 when it is decreased. In order to estimate the efficiency of the energy conversion of Ca2+ binding to mechanical work, we measured the Ca(2+)-induced Carnot cycle in the Vorticella stalk. The energy efficiency was tentatively estimated to be about 7%. With this method, we have also succeeded in measuring the isometric tension of isolated spasmoneme, the rubber-like contractile fibrous organelle in the stalk. The maximum tension of spasmoneme was approximately one tenth that of the glycerinated stalk. We speculate that the isolated spasmoneme was only partially functional due to damage sustained when it was pulled out of the stalk.

    This study aimed to evaluate the co-digestion of cheese whey and glycerin in an anaerobic sequencing batch biofilm reactor (AnSBBR) with recirculation of the liquid phase applied to biomethane production. The applied volumetric organic load (AVOL) in all conditions was 7.5 kgCOD m(-3) day(-1). The feeding time was equal to half of the cycle time. The best condition for co-digestion was the wastewater with 75 % of cheese whey and 25 % of glycerin (chemical oxygen demand (COD) basis); it achieved a productivity of 101.8 molCH4 m(-3) day(-1) and a yield of 13.3 molCH4 kgCOD(-1) with 89 % of COD removal. This represents an increase of productivity of almost 9 and 30 % when compared to the anaerobic digestion of cheese whey and glycerin alone, respectively. The co-digestion proposed is a promising solution for both pollutants with the advantage of high energy production. A first-order kinetic model was fitted efficiently to the process.

    Feed intolerance delays achievement of enteral feeding in preterm infants. Parenteral nutrition is associated with cholestasis and increased risk of sepsis. Glycerin suppositories have been used to promote gastrointestinal motility and feed tolerance. To investigate whether daily glycerin suppositories (a) reduce the time to full enteral feeding in infants born at suppository for 10 days from 24 h of age, 250 mg (24-27(+6) weeks subgroup) or 500 mg (two 250-mg suppositories; 28-31(+6) weeks subgroup); controls - no intervention. The same feeding protocol and departmental guidelines for other aspects of neonatal intensive care were used in all subjects. Analysis was by intention to treat. 54 babies were recruited (31 males), 29 randomized to receive suppositories; 48 achieved full enteral feeds. The median (range) time to full feeds was 1.6 days shorter in intervention group babies than controls, but not statistically significant: 7.4 (4.6-30.9) days versus 9.0 (4.4-13.3) days (p = 0.780; 95% confidence interval: -1.917, 2.166). No significant differences were observed in secondary outcomes. Intervention group babies passed their first stool earlier than controls (median: day 2 vs. day 4; p = 0.016). Regular glycerin suppositories did not reduce the time to full enteral feeds in infants born at <32 weeks' gestation in our setting. Copyright © 2011 S. Karger AG, Basel.

Six fermenters (1,223 ± 21 ml) were used in a replicated 3x3 Latin square arrangement with three periods of 10 d each, with 7 d for diet adaptation and 3 d for sample collections. All diets contained 75% concentrate and three dietary glycerin levels (0, 15, and 30% on dry matter basis), totaling six replicates per treatment. Fermenters were fed 72 g of dry matter/d equally divided in two meals/d, at 0800 and 2000 h. Solid and liquid dilution rates were adjusted daily to 5.5 and 11%/h, respectively. On d 8, 9, and 10, samples of 500 ml of solid and liquid digesta effluent were mixed, homogenized, and stored at -20°C. Subsamples of 10 ml were collected and preserved with 0.2 mL of a 50% H2SO4 solution for later determination of NH3-N and volatile fatty acids. Microbial biomass was isolated from fermenters for chemical analysis at the end of each experimental period. Data were analyzed using the MIXED procedure in SAS with α = 0.05. Glycerin levels did not affect apparent digestibility of DM (PLin. = 0.13; PQuad. = 0.40), OM (PLin. = 0.72; PQuad. = 0.15), NDF (PLin. = 0.38; PQuad. = 0.50) and ADF (PLin. = 0.91; PQuad. = 0.18). Also, glycerin inclusion did not affect true digestibility of DM (PLin. = 0.35; PQuad. = 0.48), and OM (PLin. = 0.08; PQuad. = 0.19). Concentrations of propionate (P glycerin inclusion. Linear increases on NH3-N concentration in digesta effluent (P glycerin inclusion in the diets. Crude protein digestibility (P = 0.04) and microbial N flow (P = 0.04) were greater in the control treatment compared with the other treatments and responded quadratically with glycerin inclusion. Furthermore, the inclusion of glycerin linearly decreased (P = 0.02) non-ammonia N flow. Glycerin levels did not affect the flows of total N (PLin. = 0.79; PQuad. = 0.35), and dietary N (PLin. = 0

    Angus × Gelbvieh rotationally crossbred yearling heifers (n = 99, yr 1; n = 105, yr 2) were used in a 2-yr randomized complete block design experiment with repeated measures to determine the effect of feeding camelina biodiesel coproducts (meal and crude glycerin) on serum concentrations of triiodothyronine, thyroxine, insulin, β-hydroxybutyrate, and glucose, as well as on growth and reproductive performance. Heifers were assigned to 1 of 15 pens, and pens were assigned initially to receive 7.03 k·•heifer(-1)·d(-1) of bromegrass hay plus 0.95 kg·heifer(-1)·d(-1) of 1 of 3 supplements for 60 d before breeding: 1) control (50% ground corn and 50% soybean meal, as-fed basis); 2) mechanically extracted camelina meal; or 3) crude glycerin (50% soybean meal, 33% ground corn, 15% crude glycerin, 2% corn gluten meal; as-fed basis). Preprandial blood samples were collected via the jugular vein on d 0, 30, and 60 of the feeding period. A 2-injection PGF(2α) protocol (d 60 and 70 of the study) was used to synchronize estrus. Heifers were artificially inseminated 12 h after estrus was first detected. Heifers not detected in estrus within 66 h received a GnRH injection and were artificially inseminated. Dietary treatment × sampling period interactions were not detected (P = 0.17 to 0.87). Dietary treatment did not affect BW (P = 0.44 to 0.59) or serum concentrations of thyroxine (P = 0.96), β-hydroxybutyrate (P = 0.46), glucose (P = 0.59), or insulin (P = 0.44). Serum concentrations of triiodothyronine were greater (P = 0.05) in heifers fed camelina meal. Additionally, dietary treatment did not affect the percentage of heifers detected in estrus before timed AI (P = 0.83), first-service pregnancy rates of those heifers detected in estrus (P = 0.97), or overall first-service pregnancy rates (P = 0.58). Heifers fed camelina meal, however, had greater (P = 0.05) first-service pregnancy rates to timed AI than did heifers fed the control and crude glycerin supplements

    Full Text Available Introduction: ulcerative colitis is a little known chronic inflammatory disease in colonic mucosa. The positive effect of epidermal growth factor was shown in a previous report, with enema use for treatment of mild to moderate left-sided manifestation of the disease. This evidence provided the basis for evaluating the efficacy and safety profile of a viscous solution of this product. Methods: thirty-one patients were randomized to three groups for daily medications during 14 days. Twelve received one 10 mg enema of epidermal growth factor dissolved in 100 mL of viscous solution whereas nine were treated with placebo enema; both groups also received 1.2 g of oral mesalamine per day. The other group included ten patients with 3 g / 100 mL of mesalamine enema. Primary end point was clinical responses after two weeks of treatment, defined as a decreased of, at least three points from baseline, the Disease Activity Index and endoscopic or histological evidences of improvement. Results: remission of disease was observed in all patients in the epidermal growth factor group, and six in both, mesalamine enema and placebo group. All the comparisons between groups showed statistically significant superiority for epidermal growth factor, the only product with significant reduction in disease activity index as well as the presence and intensity of digestive symptoms in patients after treatment. None adverse event was reported. Conclusions: the results agree with previous molecular and clinical evidences, indicating that the epidermal growth factor is effective to reduce disease activity and to induce remission. A new study involving more patients should be conducted to confirm the efficacy of the epidermal growth factor enemas.Introducción: la colitis ulcerosa es una enfermedad inflamatoria crónica de etiología poco conocida, que afecta la mucosa del colon.

    Full Text Available The nutritional value and the performance of piglets fed on diets with semipurified glycerin (SPGV and mixed (SPGM vegetable oil was determined and evaluated. Thirty-two crossbred piglets, allotted in a completely randomized block design, were used in the digestibility trial. Two types of glycerin (SPGV and SPGM and three levels of diet (4, 8 and 12% were studied. The experimental unit consisted of one piglet. Glycerins’ metabolizable energy (ME was estimated by regression of ME (kcal kg-1 intake associated with glycerin vs. glycerin intake (kg. ME as-feed-basis rates were 3,373 for SPGV and 2,932 for SPGM, or rather, the glycerins are highly available energy source for piglets. In the performance trial, 90 piglets were allotted in a completely randomized blocks design in a 2 x 4 + 1 factorial scheme, two glycerins, four levels (3, 6, 9 and 12%, five replicates (pens and two piglets per pen. A control diet with no glycerin (0% was additionally formulated. Since no effect of glycerin inclusion on pig performance occurred, it was feasible to use up to 12% of both types of glycerin on piglets feeding.

    Pseudomembranous colitis, an antibiotic-associated diarrhea, needs early diagnosis and treatment for the high fatality rate in severe cases. We report a case of pseudomembranous colitis following the use of antibiotics in febrile neutropenia (FN). A 74-year-old man with non-curative resected sigmoid colon cancer was treated with cefepime in FN induced by chemotherapy. Complications of diarrhea were seen on day 2. Paralytic ileus and disseminated intravascular coagulation were also complications. He was diagnosed as pseudomembranous colitis for Clostridium difficile toxin-positive. Vancomycin enemas were administered because oral administrations were impossible, and the effect was provided. Vancomycin enemas are an effective therapy for patients with severe pseudomembranous colitis unable to tolerate oral medications because of ileus.

    The accuracy of the double-contrast enema for the diagnosis of polypoid lesions in the presence or absence of diverticula was evaluated by retrospectively reviewing the medical records of 202 patients subjected to examination and endoscopy. Analysis of the data on 215 polypoid lesions showed that (a) the diagnostic accuracy of the examination is not affected significantly by the presence of diverticula; (b) the sensitivity of the examination is highly dependent on the size of the polyps (smaller or larger than 0.5 cm) but not on the form (sessile or pedunculated); and (c) the positive predictive value is higher in patients without diverticula. The double-contrast enema was confirmed to be a valid method for the diagnosis of polypoid lesions.

    Forty-eight bulls (335 +/- 8.6 kg of initial BW) were randomly assigned to 4 glycerin levels (0, 4, 8, and 12% of concentrate DM) with the objective of evaluating the effects of glycerin supplementation on performance, ruminal fermentation, metabolism, and carcass and meat quality in Holstein bulls fed high-concentrate diets. Concentrates were formulated to be isonitrogenous and isocaloric (assuming a glycerin ME content of 3.47 Mcal/kg of DM). Concentrate and straw were fed for ad libitum intake. Bull BW and feed consumption were recorded monthly. Additionally, rumen and blood samples were collected every month. Bulls were slaughtered after 91 d of study (460 +/- 11 kg of final BW). Hot carcass weight, carcass backfat, and conformation were recorded. The area, Warner-Bratzler shear force, and intramuscular fat content of LM were determined. Glycerin level did not affect daily concentrate intake (6.89 +/- 0.34 kg/d of DM), straw intake (1.38 +/- 0.069 kg/d of DM), total DMI (8.27 +/- 0.32 kg/d of DM), ADG (1.36 +/- 0.087 kg/d), or G:F (0.17 +/- 0.009). Similarly, rumen molar proportions of propionic, acetic, and butyric acids, and rumen liquid osmolality were unaffected by treatment. However, a decreased rumen pH (P glycerin in concentrate compared with those receiving 0, 4, or 12%. No changes were observed in carcass and meat quality. The ME content of glycerin (86% glycerol) can be assumed to be 3.47 Mcal/kg of DM in Holstein bulls fed high-concentrate diets. In addition, feeding concentrate containing up to 12.1% of glycerin does not lead to detrimental effects on performance, ruminal fermentation, metabolism, and carcass and meat quality variables.

    The effects of dietary crude glycerin on growth performance, carcass characteristics, meat quality indices, and tissue histology in growing pigs were determined in a 138-d feeding trial. Crude glycerin utilized in the trial contained 84.51% glycerin, 11.95% water, 2.91% sodium chloride, and 0.32% methanol. Eight days postweaning, 96 pigs (48 barrows and 48 gilts, average BW of 7.9 +/- 0.4 kg) were allotted to 24 pens (4 pigs/pen), with sex and BW balanced at the start of the experiment. Dietary treatments were 0, 5, and 10% crude glycerin inclusion in corn-soybean meal-based diets and were randomly assigned to pens. Diets were offered ad libitum in meal form and formulated to be equal in ME, sodium, chloride, and Lys, with other AA balanced on an ideal AA basis. Pigs and feeders were weighed every other week to determine ADG, ADFI, and G:F. At the end of the trial, all pigs were scanned using real-time ultrasound and subsequently slaughtered at a commercial abattoir. Blood samples were collected pretransport and at the time of slaughter for plasma metabolite analysis. In addition, kidney, liver, and eye tissues were collected for subsequent examination for lesions characteristic of methanol toxicity. After an overnight chilling of the carcass, loins were removed for meat quality, sensory evaluation, and fatty acid profile analysis. Pig growth, feed intake, and G:F were not affected by dietary treatment. Dietary treatment did not affect 10th-rib backfat, LM area, percent fat free lean, meat quality, or sensory evaluation. Loin ultimate pH was increased (P = 0.06) in pigs fed the 5 and 10% crude glycerin compared with pigs fed no crude glycerin (5.65 and 5.65 versus 5.57, respectively). Fatty acid profile of the LM was slightly changed by diet with the LM from pigs fed 10% crude glycerin having less linoleic acid (P glycerin diets. Dietary treatment did not affect blood metabolites or frequency of lesions in the examined tissues. This experiment demonstrated that

    The aim of this study was to evaluate the carcass traits and meat quality of Nellore bulls (279.5±16.3 initial body weight) raised on pasture supplemented with crude glycerin at 0%, 7%, 14%, 21% or 28% (DM basis). The diets were similar in energy and protein levels, and the glycerin replaced corn in the supplement. After slaughter, the carcass characteristics were measured, and the longissimus muscle was collected to determine the meat quality. The inclusion of crude glycerin in the supplement did not change (P>0.05) any of the carcass characteristics and meat quality assessed; however, the pH decreased linearly (P=0.03), and margaric acid (17:0) increased (P=0.02) in the longissimus muscle with the addition of glycerin in the diet. Our conclusion is that the inclusion of crude glycerin up to the level of 28% of dry matter in the supplement does not alter the carcass characteristics or the meat quality from animals raised on pasture.

    In cases of colorectal cancer, to correlate the spiral CT staging with water enema with the pathologic staging according to the new AJCC classification. Ninety four patients with pathologically proven carcinoma of the colon who had undergone spiral CT with water enema were evaluated. CT scans were obtained after enema involving about 600-1,200mL of water. Scanning was performed from the diaphragmatic dome to the symphysis pubis using 10mm collimation thickness, 12mm table feed, and 10mm reconstruction interval. The TNM stage, as seen on spiral CT, was determined without reference to the pathologic results. Staging was performed according to the new AJCC cancer staging manual(1997). The pathologic T-stage was T1 in four cases(4.3%), T2 in 11(11.7%), T3 in 72(76.6%), and T4 in seven(7.4%). The pathologic N-stage was N0 in 57 cases(60.6%), N1 in 25 cases(26.6%), and N2 in 12(12.8%). The pathologic M-stage was M0 in 90 cases(95.7%) and M1 in four(4.3%). The detection rate of colon cancer using spiral CT with water enema was 97.9%. At the T-stage, pathologic correlation was good in 68.1% of cases(64/94). Nine patients(9.6%) were overstaged and 21(22.3%) were understaged. At the N-stage, pathologic correlation was good in 54.3% of cases(51/94), with 27 patients(28.7%) overstaged and sixteen(17.0%) understaged. At the M-stage, pathologic correlation was good in 95.7% of cases(90/94). Four patients(4.3%) were overstaged. The accuracy of staging of colorectal carcinoma by spiral hydro-CT was 68.1% at the T-stage, 54.3% at the N-stage, and 95.7% at the M-stage. As seen on spiral CT with water enema, the T-stage tended to wards understaging and the N-stage towards overstaging.

    To evaluate the diagnostic contribution of the computed tomography (CT) enema and magnetic resonance imaging (MRI) for multifocal (multiple lesions affecting the same segment) and multicentric (multiple lesions affecting several digestive segments) bowel endometriosis. Prospective cohort study (Canadian Task Force classification II-2). Eighty-five patients. Tenon University Hospital, Paris, France. All patients received a preoperative CT enema and underwent MRI interpreted by 2 radiologists. Patients underwent colorectal resection for colorectal endometriosis from February 2009 to November 2012. Nineteen patients (22%) had multifocal lesions, and 11 patients (13%) had multicentric lesions. Six patients (7%) had both multifocal and multicentric lesions. The sensitivity, specificity, and positive and negative likelihood ratios (LRs) of MRI for the diagnosis of multifocal lesions were 0.58, 0.84, 3.55, and 0.5, respectively. The sensitivity, specificity, and positive and negative LRs of the CT enema for the diagnosis of multifocal lesions were 0.64, 0.86, 4.56, and 0.4, respectively. The sensitivity, specificity, and positive LR of MRI for the diagnosis of multicentric lesions were 1, 0.88, and 8.4, respectively. The sensitivity, specificity, and positive and negative LRs of MRI for the diagnosis of multicentric lesions were 0.46, 0.92, 5.6, and 0.59, respectively. No difference was observed between MRI and the CT enema for the diagnosis of multifocal and multicentric colorectal endometriosis. The interobserver agreement was good for MRI and the CT enema (κ = 0.45 and 0.45) for multifocality, and it was poor for both MRI and the CT enema (κ = 0.32 and 0.34) for multicentricity. Both MRI and the CT enema were able to diagnose multifocal and multicentric bowel endometriosis with similar accuracy. Copyright © 2015. Published by Elsevier Inc.

    To evaluate the usefulness of pirenzepine for diagnostic double-contrast barium enema study of the large bowel, pirenzepine and scopolamine methyl bromide (SMB) were compared in a single, blind, randomized trial. Sixty consecutive patients were enrolled in the study. Quantitative analysis of bowel distention was done by measuring the maximum diameter of the transverse colon before and after drug administration. Four independent observers blindly evaluated distention and mucosal coating of the large bowel and global quality of the images. No differences were found in the diagnostic performance between the two drugs. However, pirenzepine induced a slight but significantly larger distention of the large bowel (68 +/- 12 vs. 65 +/- 8 mm, p = 0.02). Heart rate and rhythm during the study were recorded by ECG. SMB induced tachycardia in all patients (from 72 +/- 15 to 98 +/- 24 beats/min, p pirenzepine did not (from 76 +/- 13 to 78 +/- 20, p = NS). After SMB, one-patient exhibited faintness, and some patients complained of visual accommodation defects, dryness of the mouth, and dizziness. Pirenzepine had a diagnostic performance similar to SMB in avoiding adverse effects elicited by SMB.

    Purpose: To evaluate the use of laparoscopy, CT, colonic enema (CE), and laboratory tests (white blood cell count (WBC), sedimentation rate (SR), and C-reactive protein (CRP)) in diagnosing diverticulitis of the sigmoid colon. Material and Methods: The diagnostic methods were prospectively evaluated in 88 patients, 30 of whom were referred for laparoscopy. Results: Fity-two patients were found to have sigmoid diverticulitis: 20 patients by lanparoscopy, 21 by CT, and 11 by CE combined with one positive laboratory test. Laparoscopy proved to be superior to the other diagnostic methods in diagnosing diverticulitis of the sigmoid colon. CT had a high specificity (1.0; 95% CI: 0.92-1.0) but low sensitivity (0.69; 95% CI: 0.56-0.79) in detecting diverticulitis. CE had a higher sensitivity (0.82; 95% CI: 0.71-0.90) but a lower specificity (0.81; 95% CI: 0.67-0.91) than CT. Conclusion: CT was the best method for diagnosing abdominal pathology outside the colon. CT can be recommended as the first examination in seriously ill patients where abscesses and other causes of the symptoms than diverticulitis must first be rule out. Laparoscopy is probably the most accurate method in diagnosing diverticulitis. (orig.).

    Objective The objective of this study was to investigate the association between contrast enema (CE) and clinical sepsis (CS) in premature babies (PB) and the role of antibiotics (ABs) in its prevention. Study Design A retrospective electronic chart review of preterm babies, who underwent CE during their stay in the neonatal intensive care unit. Group I includes CEs of babies exposed to AB during or within 48 hours of the procedure. Group II represents CEs of babies, not exposed to AB. Variables for both groups were collected and analyzed. Results There were 161 CEs performed in 133 babies. The overall incidence of CS after CE in preterm babies was 21/160 cases (13%). The incidence was significantly lower in Group I (1/79, 1.2%), compared with Group II (20/81, 24.7%) (p babies from Group II had positive blood culture and all 20 required AB after the CE. There were no statistical differences in the variables between the two groups. Conclusion There is a possible association between CE and CS in preterm babies. ABs given during or before the procedure prevent this complication.

    In order to improve the tensile properties of poly(ethylene terephthalate)(PET), we used the direct esterification method to synthesize PET in a home-made facility, and a certain amount of ethylene glycol (EG), one of the two starting monomers, was substituted by glycerin (GE). Four PETs with different GE contents were prepared to investigate the effect of GE on the crystallization and tensile properties of the prepared copolyester. The results showed largely improved tensile properties and increased crystallization temperature due to the possible crosslinking structure in PET by using a small amount of GE.

    Crude glycerol, also known as glycerin, is the main byproduct of the biodiesel industry. It has been estimated that up to 40,000 tons of glycerin will be produced each year by 2020. This study evaluated the value-added use of crude glycerol derived from soybean biodiesel preparation as a carbon source for heterologous protein production using the yeast Pichia pastoris. Eleven glycerin samples were obtained by methanolysis of soybean oil using different acids or bases as catalysts. Cell growth experiments showed that crude glycerol containing either potassium or sodium hydroxide resulted in 1.5-2 times higher final cell densities when compared to glycerol P.A. Finally, crude glycerol containing sodium hydroxide was successfully utilized for constitutive heterologous α-amylase production in P. pastoris. This study demonstrated that crude glycerol without any purification steps may be directly used as carbon source for protein production in P. pastoris.

    To evaluate prospectively the effect of sodium butyrate enemas on the treatment of acute and the potential influence on late radiation-induced proctitis. 31 patients had been treated with sodium butyrate enemas for radiation-induced acute grade II proctitis which had developed after 40 Gy in median. During irradiation the toxicity was evaluated weekly by the Common Toxicity Criteria (CTC) and subsequently yearly by the RTOG (Radiation Therapy Oncology Group) and LENT-SOMA scale. 23 of 31 patients (74%) experienced a decrease of CTC grade within 8 days on median. A statistical significant difference between the incidence and the severity of proctitis before start of treatment with sodium butyrate enemas compared to 14 days later and compared to the end of irradiation treatment course, respectively, was found. The median follow-up was 50 months. Twenty patients were recorded as suffering from no late proctitis symptom. Eleven patients suffered from grade I and 2 of these patients from grade II toxicity, too. No correlation was seen between the efficacy of butyrate enemas on acute proctitis and prevention or development of late toxicity, respectively.

    Full Text Available This trial aimed to evaluate the inclusion of 10%  of crude glycerin associated with roughage sources on the quality of meat aged for 1, 7 or 14 days post mortem of Nellore young bulls. Thirty feedlot animals (n = 10 with initial body weight of 416.70 ± 24.74 kg and 18 months of age were assigned to three treatments: corn silage (CS, sugar cane (SC and sugar cane bagasse (CB, using a completely randomized design. After 85 days of feeding, animals were slaughtered with 554.51 ± 38.51 kg. Samples of longissimus muscle were collected, after carcass chilling, and vacuum-packed. Diets influenced pH, meat color and subcutaneous fat (SF (p > 0.05. Animals fed CS showed higher values of b* in SF (p 0.05. Aging times influenced pH and shear force of beef (p < 0.05. Beef aged for 14 days showed higher pH (5.90 and lower shear force (2.40 kgf. Diets containing 10% crude glycerin in the DM associated with CS, SC or CB had no effect on the fatty acid profile in beef. The aging process for 14 days reduces shear force, improving meat quality.

    Full Text Available The objective of this study was to evaluate the effect of inclusion of crude glycerin (CG, corrected for protein with a byproduct of processing corn, mazoferm, on intake, production and composition of milk from Holstein cows. A total of 12 Holstein cows distributed in three Latin squares 4x4, with average production of 15 kg. The animals were fed four diets, protein and isocaloric, referring to four levels of replacement of corn grain by mixing PG-80, 0, 33.3, 66.6 and 100.0% based on the total dry matter, which corresponded respectively to 0, 40, 80 and 120 g of CG/kg dry matter. The cows were milked mechanically twice a day, making up the record of milk production of each experimental period and collected a sample of milk for evaluation of lactose, fat, protein, total solids and somatic cell count (SCC. Data were subjected to analysis of variance using the MIXED procedure of the Statistical Analysis System. The dry matter intake, the average milk production and milk production adjusted to 35 g fat / kg milk, were not affected (P>0.05 by the inclusion of GP-80 mixture in the diet. The nutritional composition of milk (fat, protein, lactose and total solids was not affected by treatments (P>0.05. The use of crude glycerin in diets to meet protein and energy requirements of animals does not compromise the dry matter intake, production, composition and milk quality for cows of low production.

    Soil microcosms were constructed and monitored to evaluate the impact of substrate addition and transient aerobic and anaerobic conditions on TNT, RDX and HMX biodegradation in grenade range soils. While TNT was rapidly biodegraded under both aerobic and anaerobic conditions with and without organic substrate, substantial biodegradation of RDX, HMX, and RDX daughter products was not observed under aerobic conditions. However, RDX and HMX were significantly biodegraded under anaerobic conditions, without accumulation of TNT or RDX daughter products (2-ADNT, 4-ADNT, MNX, DNX, and TNX). In separate microcosms containing grenade range soil, glycerin and lignosulfonate addition enhanced oxygen consumption, increasing the consumption rate >200% compared to untreated soils. Mathematical model simulations indicate that oxygen consumption rates of 5 to 20g/m(3)/d can be achieved with reasonable amendment loading rates. These results indicate that glycerin and lignosulfonate can be potentially used to stimulate RDX and HMX biodegradation by increasing oxygen consumption rates in soil. Copyright © 2016 Elsevier B.V.

    Intussusception is a common surgical emergency in infants and children. The incidence of intussusception is from one to four per 2,000 infants and children. If there is no peritonitis, perforation sign on abdominal radiographic studies, and nonresponsive shock, nonoperative reduction by pneumatic or hydrostatic enema can be performed. The purpose of this study was to compare the success rates of both the methods. Two institutional retrospective cohort studies were performed. All intussusception patients (ICD-10 code K56.1) who had visited Chiang Mai University Hospital and Siriraj Hospital from January 2006 to December 2012 were included in the study. The data were obtained by chart reviews and electronic databases, which included demographic data, symptoms, signs, and investigations. The patients were grouped according to the method of reduction followed into pneumatic reduction and hydrostatic reduction groups with the outcome being the success of the reduction technique. One hundred and seventy episodes of intussusception occurring in the patients of Chiang Mai University Hospital and Siriraj Hospital were included in this study. The success rate of pneumatic reduction was 61% and that of hydrostatic reduction was 44% (P=0.036). Multivariable analysis and adjusting of the factors by propensity scores were performed; the success rate of pneumatic reduction was 1.48 times more than that of hydrostatic reduction (P=0.036, 95% confidence interval [CI] =1.03-2.13). Both pneumatic and hydrostatic reduction can be performed safely according to the experience of the radiologist or pediatric surgeon and hospital setting. This study showed that pneumatic reduction had a higher success rate than hydrostatic reduction.

    Investigation of the ionic behavior of glycerinated muscle fibers showed that the residual structures of this biologic cellular material, lacking functional membranes, are able to discriminate between alkaline ions. The characteristics of the ionic selectivity of the glycerinated fibers change with their functional state and with the presence in the medium of certain nonionic substances. Among the more important features of ionic distribution between the membrane-free fibers and the medium are the following: (1) There is evident adsorption of potassium on the fibers, in the absence of ATP. (2) This adsorption increases in contraction and decreases in relaxation. (3) At high ionic concentrations, in contrast to what occurs at low potassium concentrations, the glycerinated muscle prefers sodium to potassium, but even under these conditions both ions are accumulated in the fibers to far greater levels than in the medium. This strongly suggests a Donnan ionic equilibrium developing parallel to the adsorption process. (4) Nonionic substances of the general anesthetic group markedly alter the ionic selectivity of the glycerinated fibers, probably by their action on the water's physical state. A mechanism is proposed for the observed ionic adsorption specific of the muscle-a mechanism in which actin-myosin coupling plays the cardinal adsorption role. In the general interpretation of the data a synthetic concept is advanced according to which an entire set of processes and factors concurs with the distribution of ions between the muscle and the medium.

    The aim of the present research work was to optimise biogas production from cattle manure by adding crude glycerin from the biodiesel industry. For this purpose, 6%v/v crude glycerin (the optimum amount according to previous research) was added to ground manure and the mixture was sonicated to enhance biodegradability prior to anaerobic co-digestion at 55 °C. Two different reactors were used: continuously stirred (CSTR) and induced bed (IBR). The methanol and pure glycerin contents of the crude glycerin used in this study were 5.6% and 49.4% (w/w), respectively. The best results when operating in CSTR were obtained for an organic loading rate (OLR) of 5.4 kg COD/m(3) day, obtaining 53.2m(3) biogas/t wet waste and 80.7% COD removal. When operating in IBR, the best results were obtained for an OLR of 6.44 kg COD/m(3)day, obtaining 89.6% COD removal and a biogas production of 56.5m(3)/t wet waste.

    Full Text Available The objective of this study was to evaluate the effects of partially replacing dry ground corn with glycerin on ruminal fermentation using a dual-flow continuous culture system. Six fermenters (1,223 ± 21 ml were used in a replicated 3x3 Latin square arrangement with three periods of 10 d each, with 7 d for diet adaptation and 3 d for sample collections. All diets contained 75% concentrate and three dietary glycerin levels (0, 15, and 30% on dry matter basis, totaling six replicates per treatment. Fermenters were fed 72 g of dry matter/d equally divided in two meals/d, at 0800 and 2000 h. Solid and liquid dilution rates were adjusted daily to 5.5 and 11%/h, respectively. On d 8, 9, and 10, samples of 500 ml of solid and liquid digesta effluent were mixed, homogenized, and stored at -20°C. Subsamples of 10 ml were collected and preserved with 0.2 mL of a 50% H2SO4 solution for later determination of NH3-N and volatile fatty acids. Microbial biomass was isolated from fermenters for chemical analysis at the end of each experimental period. Data were analyzed using the MIXED procedure in SAS with α = 0.05. Glycerin levels did not affect apparent digestibility of DM (PLin. = 0.13; PQuad. = 0.40, OM (PLin. = 0.72; PQuad. = 0.15, NDF (PLin. = 0.38; PQuad. = 0.50 and ADF (PLin. = 0.91; PQuad. = 0.18. Also, glycerin inclusion did not affect true digestibility of DM (PLin. = 0.35; PQuad. = 0.48, and OM (PLin. = 0.08; PQuad. = 0.19. Concentrations of propionate (P < 0.01 and total volatile fatty acids (P < 0.01 increased linearly and concentrations of acetate (P < 0.01, butyrate (P = 0.01, iso-valerate (P < 0.01, and total branched-chain volatile fatty acids, as well as the acetate: propionate ratio (P < 0.01 decreased with glycerin inclusion.

    Full Text Available The values of apparent metabolizable energy (AME, the AME corrected for nitrogen retention (AMEn and their respective metabolization coefficients (CME and CMEn of crude glycerin were determined utilizing the total excreta collection method with broiler chickens at different ages. A randomized complete design was used, with six treatments, six replications and ten, five and four birds per experimental unit in the periods from 11 to 20 days, from 21 to 30 days and from 31 to 40 days of age, respectively. The test food replaced the reference diet in 0; 3; 6; 9; 12 and 15% and the experimental period lasted ten days, five of which for adaptation and five for total collection. The AME and AMEn values in the phase from 11 to 20 days ranged from 2723 to 3817 and from 2672 to 3666 kcal/kg-1, respectively. In the phase from 21 to 30 days the AME and AMEn values ranged from 3723 to 3982 and from 3555 to 3945 kcal/kg-1, respectively. In the phase from 31 to 40 days the AME and AMEn values ranged from 3029 to 4143 and from 2975 to 4048 kcal/kg-1, respectively. The values of CME and CMEn linearly decreased from 11 to 20 days of age, ranging from 87.39 to 62.90 and 84.41 to 61.53%, respectively. During the phase from 21 to 30 days the coefficients also linearly decreased, ranging from 91.70 to 84.30 for CME and from 90.80 to 81.40% for CMEn. In contrast, during the phase from 31 to 40 days, the coefficients linearly increased, values ranging from 95.39 to 69.76 for CME and from 93.21 to 68.51% for CMEn. The crude glycerin can be used as an energy source in broiler diets, because it has high levels of metabolizable energy. However, the values of AME and AMEn and the metabolization coefficients of crude glycerin vary according to the levels in the reference diet and age of the birds.

    (Trans)-3,7-Dimethyl-2,6-octadien-1-ol, commonly called geraniol (Ge-OH), is an acyclic monoterpene alcohol with well-known anti-inflammatory, antitumoral, and antimicrobial properties. It is widely used as a preservative in the food industry and as an antimicrobial agent in animal farming. The present study investigated the role of Ge-OH as an anti-inflammatory and anti-dysbiotic agent in the dextran sulfate sodium (DSS)-induced colitis mouse model. Ge-OH was orally administered to C57BL/6 mice at daily doses of 30 and 120 mg kg((-1)) body weight, starting 6 days before DSS treatment and ending the day after DSS removal. Furthermore, Ge-OH 120 mg kg((-1)) dose body weight was administered via enema during the acute phase of colitis to facilitate its on-site action. The results show that orally or enema-administered Ge-OH is a powerful antimicrobial agent able to prevent colitis-associated dysbiosis and decrease the inflammatory systemic profile of colitic mice. As a whole, Ge-OH strongly improved the clinical signs of colitis and significantly reduced cyclooxygenase-2 (COX-2) expression in colonocytes and in the gut wall. Ge-OH could be a powerful drug for the treatment of intestinal inflammation and dysbiosis.

    A well-documented, clinically proven per rectum treatment for childhood constipation is needed. This phase two clinical trial evaluated the efficacy of suppositories containing free fatty acids (FFA) compared with Klyx docusate sodium and sorbitol enemas. A randomised, controlled, single-blind study was undertaken on 77 children aged between one and 17 who presented to an emergency department in Iceland and were diagnosed with constipation. In stage one, 23 patients were randomised to receive lower dose FFA suppositories or Klyx (n = 33). In stage two, 21 different patients were randomised to receive higher dose suppositories and compared with the same Klyx control subjects. The suppositories were effective at bowel emptying in 39% of the group who received the lower FFA doses and 81% of the group receiving higher doses, compared with 88% in the Klyx control group. Symptom relief was obtained in 30% of the group receiving the lower doses and 71% of the group receiving the higher doses, compared with 73% in the control group. The higher dose FFA suppositories were as effective as the Klyx enemas with regard to bowel emptying and symptom relief and might provide an important and less invasive alternative for childhood constipation. ©2016 Foundation Acta Paediatrica.

    Among the many inflammatory diseases of the colon, Crohn`s disease and ulcerative colitis occur most frequently. For primary evaluation, endoscopy has widely replaced the barium enema (BE) as diagnostic method. BE, however can provide important additional informations in the differential diagnosis of chronic inflammatory colonic diseases. Purpose of this article is the demonstration of typical, but also of atypical radiological changes in different stages of Crohn`s disease and ulcerative colitis, as well as calling attention to the importance of CT. A BE demands a refined examination technique using double contrast. All CT-examinations have to be scrutinized for changes of the bowel and mesentery. A dedicated spiral-CT examination might be indicated in a known disease in order to obtain special information. The advantage of a BE over endoscopy is a clear and reproducible demonstration of the patterns of distribution and character of the disease as well as the detection of fistulae. The classification into one or the other disease entity can be better accomplished. CT is superior in detecting bowel wall thickening, extraintestinal disease and complications. In diagnostic imaging of chronic inflammatory bowel diseases, endoscopy and radiologic techniques are used complementarily. (orig.)

    Full Text Available Ek kustha is a type of kshudra kustha described in different Ayurvedic classics. It is a vata-kaphaj disorder. The clinical symptom of Ek kustha described in Ayurveda resembles with the clinical symptom of Psoriasis. The clinical feature of Ek kustha described by Kashyap represents remission, relapse and seasonal variation, which are present in Psoriasis. Psoriasis like other skin disorders is challenge to the medical sciences. In modern medicine there is no definite treatment for this disease. The medicines, which are available to treat the disease, are not very effective and cannot be used for long-term management because of their local and systemic side effect as well as toxicity. Medicines, which are used in Ayurveda, are safe and being practiced since thousands of year. A large number of drugs and measures are described in Ayurveda for the treatment of Kustha. This study was designed to access the anti-inflammatory activity of Basti Therapy (Medicated Enema in the treatment of Ek kustha (psoriasis. The study was randomized open phase clinical trial. Basti planned for the therapy was Yoga-basti Karma in which Anuvasana basti was given using Mahanarayan tail while Niruh basti was given using Dashmula quath in accordance with Aharya Charak as mentioned in Siddhi Sthana 1/25. Keeping this view in mind we have started basti therapy in the patients of osteoarthritis and found encouraging results. The patients of age group 18 to 60 were selected on the basis of Ayurvedic signs and symptoms of Ek kustha. Observations were recorded for sharply defined erythemo-squamous lesions varying in size; presence of erythema, scaling and induration in the lesions; surface consists of non-coherent scales; positive Auspitz sign – (Bleeding occurs after scratching of scales; positive onion peeling sign/candle grease sign (after scratching the scales fall like peels of onion.

    Thirty non-castrated male lambs with 20±2.3 kg average body weight (BW) were randomly assigned to five treatments consisted of different dietary concentrations of crude glycerin (CG; 0, 3, 6, 9 and 12% on DM basis) to evaluate the effects on performance, carcass and meat quality traits. A quadratic effect was observed for performance (P=0.04), final BW (P0.05) on carcass pH neither on shear-force, cooking loss and ether extract content in longissimus. The inclusion of CG tended to reduce the Zn content in meat (P=0.09). The data suggests that CG (36.2% of glycerol and 46.5% of crude fat) may be used in diets of finishing lambs with concentrations up to 3% without negative effects on performance and main carcass traits. Moreover, inclusion of CG seems to not affect quality and safety of meat for human consumption.

    The glycerinated stalk of the peritrich ciliate Vorticella, was treated with various reagents to chemically modify the amino acid residues. The influences of these modifcations on spasmoneme contractility were investigated. First, it was confirmed that the spasmoneme contraction is not inhibited by alteration of SH groups. It was also demonstrated that chemical modification of methionine and tryptophan residues abolishes spasmoneme contractility. The reagents used for chemical modification were N-bromosuccinimide (NBS), chloramine T, and 2-hydroxy-5-nitrobenzyl bromide (HNBB), which abolished spasmoneme contractility at concentrations of 40-50 microM, 200-300 microM, and 4 mM, respectively. These results suggest that, along with Ca2+ binding proteins, there are other as yet to be identified proteins involved in contractility.

    Cell therapy with mesenchymal stem cells (MSCs) is expected to provide a new strategy for the treatment of inflammatory bowel disease (IBD). Large amounts of MSCs can be obtained from human amnion. Therefore, we investigated the effect of transplantation of human amnion-derived MSCs (hAMSCs) or enema of conditioned medium (CM) from hAMSCs into rats with 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. In the first experiment, 10-week-old male Sprague-Dawley rats were intravenously injected with hAMSCs (1 × 106 cells) 3 h after rectal administration of TNBS (45 mg/kg). In the second experiment, rats with TNBS-induced colitis received CM by enema into the colon for 3 days. Colitis was investigated by endoscopy, histology, immunohistochemistry, and by measuring mRNA expression of inflammatory mediators. Administration of hAMSCs or CM enema significantly improved the endoscopic score. In addition, these two interventions resulted in significantly decreased infiltration of neutrophils and monocytes/macrophages and decreased expression levels of TNF-α, CXCL1, and CCL2. In conclusion, transplantation of hAMSCs and CM enema provided significant improvement in rats with TNBS-induced colitis. CM from hAMSCs and hAMSCs may be new strategies for the treatment of IBD.

Little is known about their effectiveness in practice. Methods. Using a US health insurance database, we identified new-onset UP patients between January 1, 2005, and December 31, 2007, based on the following: (1 initiation of UP Rx; (2 endoscopy in prior 30 days resulting in diagnosis of UP; and (3 no prior encounters for ulcerative colitis or Crohn’s disease. We examined the incidence of therapy escalation and total costs in relation to initial UP Rx. Results. We identified 548 patients: 327 received mesalamine suppository, 138 received oral 5-ASA, and 83 received mesalamine enema, as initial UP Rx. One-third receiving oral 5-ASA experienced therapy escalation over 12 months, 21% for both mesalamine suppository and enema. Mean cumulative total cost of UP Rx over 12 months was $1552, $996, and $986 for patients beginning therapy with oral 5-ASA, mesalamine enema, and mesalamine suppository, respectively. Contrary to expert recommendations the treatments were often not continued prophylactically. Conclusions. Treatment escalation was common, and total costs of therapy were higher, in patients who initiated treatment with oral 5-ASA. Further study is necessary to assess the significance of these observations.

    Three experiments were conducted to determine the effects of dietary addition of crude glycerin on pellet production efficiency and to evaluate its effect on growth performance and digestibility in growing-finishing pigs. Three dietary treatments were created by addition of 0, 2.5, or 5% crude glycerin to barley-soybean meal-based diet, and 4 batches of each dietary treatment (2 each for grower and finisher diets) were prepared. In the manufacturing process, crude glycerin supplementation linearly increased the feeder speed and production rate (P feed production rate compared with the control. Production efficiency (kg/kWh) increased linearly (P feed increased. A growth experiment was performed with 240 barrows (30 ± 1 kg initial BW) using a 2-phase feeding program over a 12-wk period with 4 pens per treatment and 20 pigs per pen. On the last day of the growth experiment, blood samples were collected to determine circulating glucose, fructosamine, and IGF-1 concentrations. Overall growth performance was not affected (P > 0.05) by dietary treatment, and there was no effect (P > 0.05) of dietary treatment on any plasma metabolite measured. A digestibility experiment involving 9 male pigs housed in metabolic cages was used to determine the coefficients of apparent fecal digestibility and N and mineral balances. Pigs were assigned to 1 of the 3 diets in each feeding period using a 3 × 3 Latin square arrangement of treatments (43 ± 3 and 74 ± 3 kg initial BW in the growing and finishing periods, respectively). In both feeding periods, fecal digestibility of OM and ether extract were affected by dietary treatment, increasing linearly (P feeding period. In conclusion, adding crude glycerin to the diet before pelleting improved feed mill production efficiency. The addition of crude glycerin up to 5% in the diet of growing-finishing pigs had no effect on growth performance, blood metabolites, nutrient digestibility, and N balance, but more studies are needed to

    Two studies were conducted with refined glycerin (97.7 and 97.5% glycerin for studies I and II, respectively) to determine ME content and effects on growth performance and carcass and pork quality measures of finishing pigs. An energy balance study using 24 barrows (21.5 ± 0.6 kg initial BW) determined the apparent ME content of glycerin using a generalized randomized block design with 2 dietary treatments: 1) control (99.85% corn + vitamins and minerals) and 2) glycerin (30% of corn in the control diet replaced with glycerin). A 7-d adaptation was followed by a 5-d collection period for feces and urine. The energy content of diets, feces, and urine was determined by bomb calorimetry. The DE of the glycerin diet was greater (P glycerin (estimated by difference) was 3,584 kcal/kg of DM. A growth study was conducted with 128 gilts housed in groups of 4 and reared from 92.5 ± 0.24 kg of BW for a 28-d period, using a split-plot design with a 4 × 2 factorial arrangement of treatments: 1) dietary glycerin level (0, 5, 10, and 15%) and 2) preslaughter handling (gentle vs. intense). The handling treatment was included to simulate the range in handling intensities that are likely to be experienced in practice. At the end of the 28-d period, one-half of the pens on study were slaughtered and used for carcass and pork quality evaluation with 2 pigs from each pen being subjected to each of the preslaughter handling treatments. There were no interactions (P > 0.05) between dietary glycerin and preslaughter handling treatment. Dietary glycerin had no effect (P > 0.05) on growth performance, carcass measures, or meat quality. There were no differences (P > 0.05) between the gentle and intense handling treatments for carcass or pork quality measures. In conclusion, feeding glycerin to finishing pigs at up to 15% of the diet had no negative effect on growth performance or carcass and pork quality characteristics.

    Sericin/PVA/glycerin scaffolds could be fabricated using the freeze-drying technique; they showed good physical and biological properties and can be applied as wound dressings. However, freeze-drying is an energy- and time-consuming process with a high associated cost. In this study, an alternative, solvent-free, energy- and time-saving, low-cost salt-leaching technique is introduced as a green technology to produce sericin/PVA/glycerin scaffolds. We found that sericin/PVA/glycerin scaffolds were successfully fabricated without any crosslinking using a salt-leaching technique. The salt-leached sericin/PVA/glycerin scaffolds had a porous structure with pore interconnectivity. The sericin in the salt-leached scaffolds had a crystallinity that was as high as that of the freeze-dried scaffolds. Compared to the freeze-dried scaffolds with the same composition, the salt-leached sericin/PVA/glycerin scaffolds has larger pores, a lower Young's modulus, and faster rates of biodegradation and sericin release. When cultured with L929 mouse fibroblast cells, a higher number of cells were found in the salt-leached scaffolds. Furthermore, the salt-leached scaffolds were less adhesive to the wound, which would reduce pain upon removal. Therefore, salt-leached sericin/PVA/glycerin scaffolds with distinguished characteristics were introduced as another choice of wound dressing, and their production process was simpler, more energy efficient, and saved time and money compared to the freeze-dried scaffolds.

    Production of alternative fuels, such as biodiesel, from transesterification of vegetable oil driven by heterogeneous catalysts is a promising alternative to fossil diesel. However, achieving a successful substitution for a new renewable fuel depends on several quality parameters. (1)H NMR spectroscopy was used to determine the amount of methyl esters, free glycerin and acid number in the transesterification of soybean oil with methanol in the presence of hydrotalcite-type catalyst to produce biodiesel. Reaction parameters, such as temperature and time, were used to evaluate soybean oil methyl esters rate conversion. Temperatures of 100 to 180 °C and times of 20 to 240 min were tested on a 1 : 12 molar ratio soybean oil/methanol reaction. At 180 °C/240 min conditions, a rate of 94.5 wt% of methyl esters was obtained, where free glycerin and free fatty acids were not detected.

    The effects of a proprietary topical formulation containing EGCG-stearate in 100% glycerin USP were studied in two volunteer patients with recurrent herpes simplex (HSV) type 1. Application during early onset (prodromal stage) in a patient with herpes labialis prevented lesion progression. In a second patient with herpetic stomatitis, application of the formula during a later stage (inflammation stage) led to a remarkably shortened duration of symptoms. In contrast, a third patient provided 100% glycerin USP only as placebo failed to demonstrate any therapeutic or preventive effect against lesion occurrence or duration of lesion and healing time. These results suggest that this proprietary topical preparation could be used effectively to prevent and treat HSV-induced symptoms, and warrants further clinical investigation.

    The simultaneous production of high quality biodiesel and glycerin was realized by a bench-scale process using expanded-bed reactors packed with cation- and anion-exchange resins. The mixed-solution of crude Jatropha oil and methanol at a stoichiometric molar ratio was supplied to the process. The free fatty acid as well as triglyceride was completely converted to biodiesel. All by-products were adsorbed on the resin and the effluent from the process was free from them. The effluent fully met the international biodiesel standard specifications without any downstream purification processes except for removing methanol. The glycerin adsorbed on the resin was completely recovered as a transparent methanol solution during regeneration of the resin.

    An experiment was conducted with 72 Bovans Brown laying hens to determine the effect of dietary crude glycerin on laying performance; egg quality; retention of N, Ca, and P; and metabolizability of energy. The dietary treatments consisted of a control corn-soybean diet containing 6% corn starch (17% CP, 2,775 kcal/kg of AME(n), 0.81% lysine, 0.36% methionine, 3.60% Ca, and 0.37% available P) and 3 experimental diets. In the experimental diets, 2, 4, or 6% crude glycerin (a coproduct of commercial biodiesel production from rapeseed) was substituted for corn starch. During the experimental period (28 to 53 wk of hen age), the dietary level of glycerin had no significant effects on performance indices [i.e., egg production (mean value of all 4 dietary treatments was 95.6%), egg weight (60.4 g), daily egg mass (57.8 g/hen), daily feed consumption (121 g/hen), and feed conversion (0.477 g of egg mass/g of feed consumed)]. No significant treatment effects were found for egg quality parameters (albumen height, Haugh units, yolk color and thickness, density and breaking strength of eggshell), excretion and retention of N, Ca and P, or metabolizability of energy. Linear regression analysis revealed that the AME(n) value of crude glycerol was 3,970 kcal/kg (as-is basis). The results of this study demonstrated that crude glycerin may be incorporated to a level of 6% in the diet of laying hens without any detrimental effect on egg performance, egg quality, nutrient retention, and metabolizability of energy.

    Highlights: •B{sub 4}C powder was synthesized from a condensed H{sub 3}BO{sub 3}-glycerin product with tartaric acid added. •A precursor consisting of B{sub 2}O{sub 3} and carbon was prepared by the thermal decomposition in air. •The precursors had a three-dimensional bicontinuous B{sub 2}O{sub 3}/carbon network structure. •The dispersion state became more homogeneous and finer with the addition of tartaric acid. •The complete formation of B{sub 4}C powder was achieved at 1250 °C within a shorter heat treatment time. -- Abstract: The effect of the addition of tartaric acid on the synthesis of boron carbide (B{sub 4}C) powder from a condensed boric acid (H{sub 3}BO{sub 3})–glycerin product was investigated in this study. The condensed product was prepared by dehydration condensation after directly mixing equimolar amounts of H{sub 3}BO{sub 3} and glycerin with the addition of 0–50 mol% tartaric acid (based on glycerin), which was followed by thermal decomposition in air to obtain a precursor powder from which excess carbon had been eliminated. The dispersion state of the boron oxide (B{sub 2}O{sub 3}) and carbon components in the precursor prepared from the condensed product with 25 mol% tartaric acid added was finer than that without tartaric acid added, in which both precursors had a three-dimensional bicontinuous B{sub 2}O{sub 3}/carbon network structure. The complete formation of crystalline B{sub 4}C powder was achieved at 1250 °C within a shorter heat treatment time for the precursor with a fine dispersion state. The synthesized B{sub 4}C powders became fine owing to the increased number of nucleation sites.

    Full Text Available Background and Aim: During root canal therapy, it is necessary to remove as many bacteria as possible from the root canal. The use of medicaments is recommended to reduce the microbial population prior to root filling. Calcium hydroxide pastes have been used because of their antibacterial effects and the ability of tissue dissolving. The aim of this study was to evaluate the effect of calcium hydroxide/glycerine mixture, calcium hydroxide/normal saline mixture and calcium hydroxide/distilled water mixture on root dentin microhardness in storage times of 7 and 14 days.Materials and Methods: In this in vitro study, fifteen extracted maxillary canines and central incisors were selected. The crowns of the teeth were removed and the canals were prepared. Teeth were sectioned transversally to produce a total of 30 dentin discs from the middle third of the roots. Specimens were divided into three groups of 10 discs each. Dentin samples were subjected to calcium hydroxide/glycerine, calcium hydroxide/normal saline and calcium hydroxide/distilled water mixtures for 7 and 14 days. Dentin microhardness was measured by a Vickers indenter with a load of 200 g for 15 seconds. Data were analyzed using ANOVA, Paired t-test and LSD with p<0.05 as the level of significance.Results: Statistical analysis showed that all three mixtures decreased dentin microhardness. After 7 days, reduction in dentin microhardness by calcium hydroxide/glycerine combination was significantly higher than calcium hydroxide/normal saline and calcium hydroxide/distilled water combinations. After 14 days, reduction in dentin microhardness by calcium hydroxide/distilled water combination was significantly higher than the other two groups.Conclusion: Based on the results of this study, the use of calcium hydroxide combinations for intracanal dressing reduces dentin microhardness. After 7 days calcium hydroxide/glycerine combination and after 14 days calcium hydroxide/distilled water

    The sensitivity between double contrast barium enema (DCBE) and sigmoideoscopy in diagnosing neoplastic lesions in the sigmoid colon was compared in patients with diverticulosis. In 52 patients with severe diverticulosis ([>=] 15 diverticulas) the DCBE detected one out of 4 polyps found by sigmoideoscopy. In the remaining 54 patients with mild diverticulosis (< 15 diverticulas) DCBE detected 7 out of 10 polyps found by sigmoideoscopy. Successful bowel preparation did not influence the outcome of the DCBE. Sigmoideoscopy was incomplete in 17 (16%) of the patients; females were more difficult to examine than males (p=0.012), as were those with a previous pelvic operation (p=0.032). We conclude that neither DCBE nor sigmoideoscopy alone is sufficient to detect all neoplastic lesions in the sigmoid colon in patients with sigmoid diverticulosis of the colon. (orig.).

Fifty-three patients (mean age 70 years) with extra-rectal colon cancer proven by colonoscopy and biopsy were prospectively evaluated by preoperative WE-MDCT. CT scans were both intraluminal (water enema or WE) and intravenous (iodinated) contrast enhanced (CE). All patients underwent surgery. Tumors were classified with the TNM staging system. Noted CT features were: tumor size and location; tumor form and edges; spread to the pericolic fat or neighboring organs; thickening of retroperitoneal fascia; number, size, and enhancement of the peritumoral lymph nodes. Tumors were classified on CT into 3 T-stage groups: T1/T2, T3, and T4. Lymph nodes were classified by their density after injection [positive over 100 Hounsfield units (HU)]. Tumor localization to the specific colon segment was correct in all the cases. The agreement between WE-MDCT staging and histopathology staging was good (k = 0.64). An irregular and bowl-shaped aspect of the external edges of tumor provided excellent sensitivity for T3/T4 inclusion (Se 97.7%, NPV 85.7%). Thickening of a fascia or the abdominal wall provided good specificity for T4 stage (Sp 88.1%, NPV 94.9%). Enhancement over 100 HU of at least one peritumoral lymph node was the best criterion of N+ staging (Sp 67.7%, NPV 87.5%). WE-MDCT permits good staging of colon cancer based on objective features.

    The objective was to determine whether crude glycerin could partially replace concentrate ingredients in corn silage- or cottonseed hull-based diets formulated to support minimal milk fat production without reducing milk production. Multiparous, lactating Holstein cows (n=24; 116 ± 13d in milk) were assigned to dietary treatments arranged in a 2 × 3 factorial design; namely, 2 dietary roughage sources (cottonseed hulls or corn silage) and 3 dietary concentrations of glycerin [0, 5, or 10% on a dry matter (DM) basis]. Four different cows received each dietary treatment in each of 3 periods such that each diet was evaluated using 12 cows. Crude glycerin, produced using soybean oil, contained 12% water, 5% oil, 6.8% sodium chloride, and 0.4% methanol. Glycerin partially replaced ground corn, corn gluten feed, and citrus pulp. Diets of minimum fiber concentrations were fed to lactating dairy cows and resulted in low concentrations of milk fat (averaging 3.12% for cows fed diets without glycerin). The effects of glycerin on cow performance and ruminal measurements were the same for both dietary roughage sources with the exception of feed efficiency. Replacing concentrate with crude glycerin at 5% of dietary DM increased DM intake without increasing milk yield. Concentration and yield of milk fat were reduced when glycerin was fed at 10% of dietary DM. This was accompanied by a 30% reduction in apparent total-tract digestion of dietary neutral detergent fiber. Crude glycerin affected the microbial population in the rumen as evidenced by increased molar proportions of propionic, butyric, and valeric acids and decreased molar proportions of acetic acid. Efficiency of N utilization was improved as evidenced by lower concentrations of blood urea nitrogen and ruminal ammonia-N. Cows fed cottonseed hull-based diets consumed 5.3 kg/d more DM but produced only 1.7 kg/d more milk, resulting in reduced efficiency. Increased production of ruminal microbial protein, molar

    The effect on process performance of adding increasing proportions of biodiesel waste glycerin (BWG) to municipal wastewater sludge (MWS) was studied using two 1300 L pilot-scale digesters under mesophilic conditions at 20 days SRT. The highest proportion of BWG that did not cause a process upset was determined to be 23% and 35% of the total 1.04 kg VS/(m(3)d) and 2.38 kg COD/(m(3)d) loadings, respectively. At this loading, the biogas and methane production rates in the test digester were 1.65 and 1.83 times greater than of those in the control digester which received only MWS, respectively. The COD and VS removal rates at this loading in the test digester were 1.82 and 1.63-fold those of the control digester, respectively. Process instability was observed when the proportion of BWG in the test digester feed was 31% and 46% of the 1.18 kg VS/(m(3)d) and 2.88 kg COD/(m(3)d) loadings, respectively.

    To meet the growing demand of environmental protection and resource saving, it is imperative to explore bio-based elastomers as next-generation dielectric elastomers (DEs). In this study, we used a bio-based gelatin/glycerin (GG) elastomer as the DE matrix because GG exhibits high dielectric constant (ɛr). Cellulose nanocrystals (CNCs), extracted from natural cellulose fibers, were used to improve the mechanical strength of GG elastomer. The results showed that CNCs with a large number of hydroxyl groups disrupted the hydrogen bonds between gelatin molecules and formed new stronger hydrogen bonds with gelatin molecules. A good interfacial adhesion between CNCs and GG was formed, and thus a good dispersion of CNCs in GG matrix was obtained, leading to the improved mechanical strength of GG. More interestingly, the ɛr of GG elastomer was obviously increased by adding 5 wt% of CNCs, ascribed to the increase in the polarizability of gelatin chains caused by the disruption of hydrogen bonds of gelatin. As a result, a 230% increase in the actuated strain at low electric field of GG was obtained by adding 5 wt% of CNCs. Since CNCs, gelatin and glycerol are all bio-based, this study offers a new method to prepare high performance DE for its application in biological and medical fields.

    Full Text Available In order to improve patient's compliance in taking glycerine trinitrate (GTN nylon hollow fiber which has been successfully used for release of chlorhexidine diacetate and levonorgestrel was employed to make nylon hollow fiber releasing GTN. Hollow nylon fibres of external diameter 0.63 mm, 75 mm long with an internal capacity of 16 μl, were filled with GTN (190 mg/ml in 70% ethanol (v/v or vehicle alone and the ends were heat-sealed. The fibers were then immersed in 10 ml of 0.9% (w/v saline in a separating funnel. The GTN release pattern from fiber, the effect of the product on blood pressure and its potential dermal toxicity were assessed. The release of GTN from the fibres was approximately 2.7 μg/min when the fibres contained 16 mg of drug. The results showed that the amount of GTN within the single fibre was enough to reduce blood pressure significantly, while it did not show significant dermal toxicity. It is concluded that GTN fiber, if used as monofilament, is not an alternative method for GTN delivery.

    Chemical modification of glycerinated stalks of Vorticella with TNM is used to investigate the role of tyrosine residues in the Ca(2+)-induced contraction of the spasmoneme. Tetranitromethane (TNM) is often employed as a specific reagent for the nitration of tyrosine residues in a protein at neutral and slightly alkaline pHs although TNM can also oxidize cysteine residues in the acidic and neutral pH range. Prior incubation with Ca(2+) of stalks to be treated with TNM can protect the spasmoneme from irreversible denaturation. On the other hand, TNM treatment in the absence of free Ca(2+) causes an irreversible denaturation of the spasmoneme. It was revealed by us that an isolated Ca(2+)-binding protein called spasmin could not bind with Ca(2+) after TNM treatment, even if the treatment was performed in the presence of Ca(2+). In an additional experiment, we confirmed that the chemical modification of cysteine residues in the spasmoneme with N-7-dimethyl-amino-4methyl- coumarinyl- maleimide (DACM) has no effect on the contractibility. These results suggest that tyrosine residues in spasmin are essential for spasmoneme contraction and are protected from TNM in the presence of Ca(2+) when spasmin binds with its receptor protein in the spasmoneme.

    Full Text Available Assessment of carcass and meat characteristics of Holstein-Zebu crossbred young bulls finished in feedlot with crude glycerin levels (0, 60, 120, and 240 g kg-1 dry matter in replace of ground pearl millet grain and babassu mesocarp bran mixture-based diets. Twenty four bulls 30-month-old and initial average body weight of 390 ± 31.5 kg were used. The animals were distributed in a completely randomized design with four treatments and six replicates. The absolute weight (kg of commercial cuts did not fit any of the tested regression models. However, the weight of the short ribs and the pistol cut were higher for animals fed with crude glycerin in relation to those fed without inclusion of this food in the diet. The proportion of the commercial cuts, however, was not changed. The increase of the crude glycerin levels linearly increased the proportion of carcass fat and reduced the muscle proportion, without changing the proportion of bone and the edible portion of the carcasses. The ratio muscle/fat reduced linearly with the advance of crude glycerin level of diets. The color of the meat, evaluated subjectively, increased linearly with the advance of crude glycerin levels of the diets, from dark red to slightly dark red. The texture, marbling, shear force, thawing loss and cooking loss were not changed by dietary levels of crude glycerin. The inclusion of up to 240 g kg-1 of crude glycerin in the diets increases the proportion of fat without changing the marketable portion of carcasses. The benefits to the meat quality refer to the improvement of color, without changing the other characteristics of economic interest.

    To study the usefulness of glycerin fatty acid ester Poem TR-FB (TR-FB) and Poem TR-HB (TR-HB) as lubricants, pressure transmission ratio, ejection force, disintegration time, and tensile strength were measured at different concentrations and mixing times for granules and tablets. When each lubricant was mixed at 0.1-3.0%, the increase in the pressure transmission ratio that was equal to or greater than that of Mg-St as well as the reduction in the ejection force was observed at a low concentration in both TR-FB and TR-HB, proving that they have excellent lubrication performance. The granules that were lubricated with TR-FB and TR-HB at even low concentration of 0.4% showed a more stable and sufficiently lower ejection force than with Mg-St from the first tablet after the start of compression. When they were mixed for 5-60 min, while the mixture with Mg-St showed a low pressure transmission ratio of 82% and a high ejection force of 500 N in the first tablet even when the mixing time was 60 min, a high pressure transmission ratio and a low ejection force were observed in TR-FB and TR-HB from the first tablet after mixing for 5-60 min, and these were maintained thereafter. As for the disintegration time and the tensile strength, a prolonged disintegration time and a decreased tensile strength, which are disadvantages of Mg-St, were not observed in TR-FB and TR-HB. Based on these results, it was concluded that TR-FB and TR-HB are useful as alternative lubricants to Mg-St. Copyright 2009 Elsevier B.V. All rights reserved.

    Full Text Available Two experiments were carried out to determine the nutritional value of neutralized semi-purified glycerin (NSPG and to evaluate the performance of pre-starting piglets (6-15 kg fed on diets containing increasing levels of NSPG. In Experiment I, a digestibility trial with 30 barrows (11.80 ± 5.12 kg live weight was conducted, in which they were allotted in a randomized block design. Replacement levels of the basal diet by NSPG were 3, 6, 9, and 12%. The values (as-fed-base of digestible energy (DE and metabolizable energy (ME of NSPG were 3535 and 3279 kcal/kg, respectively. In Experiment II, 135 piglets, weaned at 21 days of age (6.85 ± 1.28 to 15.04 ± 2.06 kg, were allotted in a randomized-block design. Treatments consisted of five diets (3, 6, 9, and 12% NSPG as well as a control diet with 0% of NSPG, with nine replications, and three piglets per experimental unit. The results show that, in the pre-starting I (6-10 kg phase, adding NSPG promoted a linear improvement in the average daily gain (ADG and the feed-to-gain ratio (F:G. For the total period (6-15 kg, only linear improvements (P ? 0.05 to ADG were observed. The plasma variables were not influenced (P ? 0.05 by the inclusion of NSPG, as it remained within the biological range of the species. The results suggest that up to 12% NSPG can be included in the diets of piglets (6-15 kg without impairing the plasmatic variables, performance, and economic feasibility.

    In recent years, the number of cancer patients and their families desiring palliative home-based care in Japan has increased. Subarachnoid phenol-glycerin block therapy is offered to relieve refractory anal pain in cancer patients, and to reduce the side effects of systemic administration of opioids, such as drowsiness. The effects of phenol-glycerin, which is a medicine used for neurodegenerative diseases, lasted for 1 week to 3 months. Eight patients with this manipulation showed a significant improvement in their pain level, calculated by the numerical rating scale(NRS). Five of these patients could proceed to homebased care. It is important to establish common guidelines for the management of phenol-glycerin. The participation of pharmacists in the palliative care team will contribute to further growth of home-based care.

    AIM: To determine whether the timing of buscopan administration during double-contrast barium enema examination (DCBE) affects diagnostic quality. MATERIALS AND METHODS: In a prospective setting, 100 consecutive adult out-patients referred for DCBE received 20 mg buscopan (hyoscine-N-butylbromide) intravenously, either before infusion of barium suspension (Group A) or after barium infusion and gas insufflation (Group B). A subjective assessment of ease of contrast medium infusion was made at the time of examination and the films subsequently analysed by two radiologists unaware of the mode of relaxant administration, who noted the quality of mucosal coating and made subjective and objective measurements of segmental distension. RESULTS: There was no significant difference in screening times, infusion difficulty or colonic contrast medium coating between the two groups. Subjective assessment of distension of the caecum, ascending colon, transverse colon and rectum were not significantly different. Patients receiving intravenous relaxant after barium and gas infusion had less subjective descending (P = 0.05) and sigmoid (P = 0.04) colon distension, but there was no significant difference with respect to maximal bowel diameter in any of the segments measured. CONCLUSION: The timing of intravenous administration during DCBE is likely to have no significant effect on the diagnostic quality of the study. Elson, E.M. (2000)

    Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant trait characterized by presentation of colorectal cancer (CRC) at an early age and by an increased risk of other primary malignancies, including those of the endometrium. ovaries, stomach, small bowel, upper biliary tract, skin, and brain, as well as by transitional cell carcinoma (TCC) that especially involves the renal pelvis and ureter. Because specific genetic mutations causing HNPCC have been recently discovered, genetic screening options have been developed for some families. Subsequently, radiology has an increasing role in surveillance for and management of these HNPCC-associated tumours. Although colonoscopy is the mainstay of a screening regimen for colon cancer, the barium enema has been a standard radiologic investigation. Further, computed tomography (CT) colonography (now practised in various centres) will, with further refinement, prove to be of increasing value. Ultrasonography is a standard investigation for endometrial and ovarian cancer, with CT and magnetic resonance (MR) imaging often playing a central role. As for TCC, intravenous urography (IVU) had been a standard investigation tool. However, with continued evolution of multidetector row CT with postprocessing manipulation (CT urography [CTU]), the role of IVU is diminishing in most centres. Newfoundland has a high prevalence of HNPCC exhibiting a broad range of manifestations. In this article, radiologic images of various tumours from individuals with HNPCC demonstrate a radiologic spectrum of this fascinating hereditary disease. Screening implications and specific screening methods are reviewed. (author)

    Thiel-fixed specimens have outstandingly lifelike visual and haptic properties. However, the original Thiel method is expensive and requires an elaborate setup. It is therefore of principal interest to modify the Thiel method in order to make it available to a broader user group. A modified Thiel embalming method will be described in detail and compared to ethanol-glycerin fixation with the help of illustrative examples. The visual properties, haptic properties, the usability for performing histological investigations, costs and potential health aspects will be considered. Tissues fixed with the modified Thiel technique gave results similar to the original method, providing more realistic visual and haptic properties than ethanol-glycerin embalming. However, Thiel fixation is significantly more expensive and requires more precautions to minimize potential health hazards than ethanol-glycerin-fixed tissues. In contrast to ethanol-glycerin-fixed specimens, the Thiel-fixed specimens are not suitable for histological investigations. Both modes of fixation are inappropriate for biomechanical testing. Modified Thiel embalming simplifies the availability of body donors with lifelike properties and has cost-saving advantages to the original technique. Thiel-embalmed body donors are ideally suited for clinical workshops but have restrictions for student dissection courses in facilities with limited storage space, air circulation or technical staff. Vice versa, ethanol-glycerin-fixed body donors are well suited for student dissection courses in such an environment but are limited in their use for clinical workshops. Modified Thiel embalming therefore ideally complements ethanol-glycerin fixation in order to provide customized solutions for clinical workshops and student dissection courses in a wide range of applications.

    The addition of plasticizers seeks improvements in mechanical properties of dense membranes of silk fibroin with possible interactions by hydrogen bonds. The aim of the present study was to produce and characterize dense membranes of silk fibroin containing glycerin in two different concentrations. The characterization of the membranes was performed from scanning electron microscopy (SEM), mechanical traction tests, infrared spectroscopy (FTIR-ATR) and X-ray diffraction (XRD). The results indicated that the addition of glycerin allowed obtaining homogeneous and more crystalline membranes and improved their properties of elongation. (author)

    This study was initiated when it was suspected that syringe blockage experienced upon administration of a compounded rifampin suspension was caused by the recrystallization of toxic glycol solvates of the drug. Single crystal X-ray structure analysis, powder X-ray diffraction, thermal analysis and gas chromatography were used to identify the ethylene glycol in the solvate crystals recovered from the suspension. Controlled crystallization and solubility studies were used to determine the ease with which toxic glycol solvates crystallized from glycerin and propylene glycol contaminated with either ethylene or diethylene glycol. The single crystal structures of two distinct ethylene glycol solvates of rifampin were solved while thermal analysis, GC analysis and solubility studies confirmed that diethylene glycol solvates of the drug also crystallized. Controlled crystallization studies showed that crystallization of the rifampin solvates from glycerin and propylene glycol depended on the level of contamination and changes in the solubility of the drug in the contaminated solvents. Although the exact source of the ethylene glycol found in the compounded rifampin suspension is not known, the results of this study show how important it is to ensure that the drug and excipients comply with pharmacopeial or FDA standards.

    Objectives: the main objective of the present work was to determine the diagnostic value of CT-enterography with water enema (CTe-WE) in the assessment of the ileocolic anastomosis in patients with Crohn's disease (CD). The prevalence of synchronous inflammatory lesions (SILs) involving gastrointestinal segments distinct from the anastomosis was also determined. Further, the association between the type of ileocolic anastomosis and the behavior (i.e. inflammatory, stricturing, penetrating) of CD recurrence was evaluated. Methods: 51 patients were retrospectively included (26 [51%] male and 25 [49%] female; mean age: 52.88 years ± 13.35). Ileocolic anastomoses were: 18 (35.3%) stapled side-to-side, 17 (33.3%) end-to-side, and 16 (31.4%) end-to-end. CTe-WEs were reviewed in consensus by two gastrointestinal radiologists. Endoscopy and medical records were used as reference standards. Results: CTe-WE yielded 95.35% sensitivity (CI 95%: 84.19–99.43%), 75.00% specificity (CI 95%: 34.91–96.81%), and 92.15% diagnostic accuracy (CI 95%: 81.31–98.02%). Anastomotic recurrence was found in 41/51 (80.4%) patients, including 30/41 (73.2%) cases of isolated anastomotic recurrence, and 11/41 (26.8%) cases of anastomotic recurrence with a SIL. A significant lower prevalence of stricturing recurrence was observed in patients with stapled side-to-side anastomoses (p = 0.033). Conclusions: CTe-WE provides a good distension of both sides of ileocolic anastomoses allowing the detection of SILs.

    There have been few innovations in the management of penetrating trauma of the flank and back since that reported by Peck and Berne in 1981. During 1984-1985 our Trauma Service treated 119 patients with injuries in these areas. In 56 patients management was based on the results of the contrast-enhanced CT enema (CECTE), a computerized tomographic technique designed to delineate all of the retroperitoneal viscera by simultaneously opacifying the small bowel, duodenum, colon, GU tract, and major vessels. Specific radiographic findings were present on 44 scans. Twelve scans were negative. Six scans were considered indications for angiography because of the proximity of the identified missile wounds or their hematomas to major vascular structures. One of these arteriograms revealed a renal artery pseudoaneurysm which would otherwise have remained undiagnosed. In 30 cases the penetrating wounds were well delineated by CECTE, and their nature and location were considered appropriate for nonoperative management. None required subsequent exploration. In eight cases CECTE demonstrated that the wounds were located so as to place specific viscera at risk for significant injury, but no definite injury was identified. Five of these patients were successfully managed by further evaluation and close observation, two were explored, and one signed out of the hospital. No scan demonstrated extravasation from a hollow viscus. Overall, 52 of our 56 patients (92%) were successfully managed nonoperatively on the basis of the interpretation of their CECTE findings. CECTE can be useful in the management of stable patients with penetrating trauma to the back and flank by identifying the nature and location of the resulting retroperitoneal injuries.(ABSTRACT TRUNCATED AT 250 WORDS)

    To compare the CT colonography (CTC) and double-contrast barium enema (DCBE) for colonic evaluation in patients with renal insufficiency. Two sequential groups of consecutive patients with renal insufficiency who had a similar risk for colorectal cancer, were examined by DCBE (n = 182; mean {+-} SD in age, 51 {+-} 6.4 years) and CTC (n = 176; 50 {+-} 6.7 years), respectively. CTC was performed after colon cleansing with 250-mL magnesium citrate (n = 87) or 4-L polyethylene glycol (n = 89) and fecal tagging. DCBE was performed after preparation with 250-mL magnesium citrate. Patients with colonic polyps/masses of {>=} 6 mm were subsequently recommended to undergo a colonoscopy. Diagnostic yield and positive predictive value (PPV) for colonic polyps/masses, examination quality, and examination-related serum electrolyte change were retrospectively compared between the two groups. Both the CTC and DCBE were positive for colonic polyps/masses in 28 (16%) of 176 and 11 (6%) of 182 patients, respectively (p = 0.004). Among patients with positive findings, 17 CTC and six DCBE patients subsequently underwent a colonoscopy and yielded a PPV of 88% (15 of 17 patients) and 50% (3 of 6 patients), respectively (p = 0.089). Thirteen patients with adenomatous lesions were detected in the CTC group (adenocarcinoma [n = 1], advanced adenoma [n = 6], and non-advanced adenoma [n = 6]), as compared with two patients (each with adenocarcinoma and advanced adenoma) in the DCBE group (p = 0.003). Six (3%) of 176 CTC and 16 (9%) of 182 DCBE examinations deemed to be inadequate (p 0.046). Electrolyte changes were similar in the two groups. In patients with renal insufficiency, CTC has a higher diagnostic yield and a marginally higher PPV for detecting colorectal neoplasia, despite a similar diagnostic yield for adenocarcinoma, and a lower rate of inadequate examinations as compared with DCBE.

    Background: Enemas are used by individuals with constipation and are often required before certain medical diagnostic procedures and surgical interventions. However, abnormalities in serum electrolyte concentrations have been associated with enema use. Objective: The aim of this study was to determine the changes in serum electrolyte concentrations (phosphorus, calcium, sodium, and potassium) and urinary phosphorus elimination after the administration of a sodium phosphate enema. Methods: Healthy volunteers aged 35 to 70 years were eligible for this open-label, randomized, controlled, 2-period, crossover clinical trial at the Clinical Research Unit of the University Hospital of Navarra, Pamplona, Spain. The study comprised 2 one-day periods separated by a 7-day washout. All subjects were randomly assigned in a 1:1 ratio to 1 of 2 study sequences: (1) a single dose of Enema Casen® 250 mL in the first period followed by no treatment (control) in the second period, or (2) no treatment in the first period followed by a single dose of the study drug in the second period. The sequence of treatment was assigned using a randomization table that was prepared before the beginning of the study. Serum concentrations of phosphorus, sodium, potassium, and calcium were measured in both periods. Urinary phosphorus elimination was measured for 12 hours after enema administration (Ae0–12) in a subset of the subjects in the second period. Adverse events (AEs) were monitored by the investigators throughout the study. Normal ranges for the electrolytes were as follows: phosphorus, 2.5 to 5 mg/dL; calcium, 8.5 to 10.5 mg/dL; sodium, 135 to 145 mEq/L; and potassium, 3.5 to 5 mEq/L. Results: Twenty-four subjects (12 men, 12 women; mean [SD] age, 47.8 [9.6] years [range, 36–68 years]) participated in the study. All of the subjects were white and none were smokers. Twelve hours after enema administration, mean serum phosphorus and sodium concentrations increased by a mean of 1.18 mg

    Ratcliffe, J.F.

    Stercoral obstruction in a young woman with disseminated phaeochromocytoma was diagnosed and treated successfully using an enema of isosmolar iohexol (Omnipaque) and 1% polysorbate 80 (Tween 80) without complication. Surgical intervention was thus avoided. A low osmolality water-soluble contrast medium (iohexol 150 mg I/ml) with a wetting agent (1% Tween 80) was used because a barium suspension would have inspissated, exacerbating the constipation and a hyperosmolar contrast medium might have precipitated a hypertensive crisis and destablished her critical salt and water balance.

    Full Text Available Abstract Background and Aims The standard whole-colon tests used to investigate patients with symptoms of colorectal cancer are barium enema and colonoscopy. Colonoscopy is the reference test but is technically difficult, resource intensive, and associated with adverse events, especially in the elderly. Barium enema is safer but has reduced sensitivity for cancer. CT colonography ("virtual colonoscopy" is a newer alternative that may combine high sensitivity for cancer with safety and patient acceptability. The SIGGAR trial aims to determine the diagnostic efficacy, acceptability, and economic costs associated with this new technology. Methods The SIGGAR trial is a multi-centre randomised comparison of CT colonography versus standard investigation (barium enema or colonoscopy, the latter determined by individual clinician preference. Diagnostic efficacy for colorectal cancer and colonic polyps measuring 1 cm or larger will be determined, as will the physical and psychological morbidity associated with each diagnostic test, the latter via questionnaires developed from qualitative interviews. The economic costs of making or excluding a diagnosis will be determined for each diagnostic test and information from the trial and other data from the literature will be used to populate models framed to summarise the health effects and costs of alternative approaches to detection of significant colonic neoplasia in patients of different ages, prior risks and preferences. This analysis will focus particularly on the frequency, clinical relevance, costs, and psychological and physical morbidity associated with detection of extracolonic lesions by CT colonography. Results Recruitment commenced in March 2004 and at the time of writing (July 2007 5025 patients have been randomised. A lower than expected prevalence of end-points in the barium enema sub-trial has caused an increase in sample size. In addition to the study protocol, we describe our approach to

    Glycerin soap has been colored with red pigment from Streptomyces K-4 B and Dayak onion (Eleutherine palmifolia (L.) Merr). Both red pigments from Streptomyces K-4B and Dayak onion were extracted with ethanol by maceration method, followed with soxhlet extraction. The concentration of red pigment added was varied (0, 200, 300, 400 μL) to evaluate the best product. The resulted glycerine soaps were characterized and analyzed based on SNI 06-3532-1994. The research results indicated that the glycerine soap has water content ranged from 0.36% to 12.56%; the amount of fatty acid ranged from 14% to 36.75%; the amount of free fatty acids ranged from 0% to 0.37%; the non-saponifiable fat ranged from 0.001 to 0.019%; the pH ranged from 10.33 to 11.06; the foam stability ranged from 0.61% to 89.09%. The results of analysis of variance showed that the effect between treatments significantly different at 95% confidence level (α = 0.05) on the characteristics of glycerine soap.

    Anaerobic digestion of organic waste plays an important role for the development of sustainable energy supply based on renewable resources. For further process optimization of anaerobic digestion, biogas production with the commonly used substrates, grass, maize, and green weed silage, together with industrial glycerine, were analyzed by the Weender analysis/van Soest method, and a simulation study was performed, based on the International Water Association's (IWA) Anaerobic Digestion Model No. 1 (ADM1). The simplex algorithm was applied to optimize kinetic constants for disintegration and hydrolysis steps for all examined substrates. Consequently, new parameters were determined for each evaluated substrate, tested against experimental cumulative biogas production results, and assessed against ADM1 default values for disintegration and hydrolysis kinetic constants, where the ADM1 values for mesophilic high rate and ADM1 values for solids were used. Results of the optimization lead to a precise prediction of the kinetics of anaerobic degradation of complex substrates.

    The use of renewable resources has been increasing, due to the development of materials that have viable applications that are environmentally friendly. In this paper, a polyester was synthesized from glycerin, with the addition of adipic acid in a molar ratio of 1: 1.5, with dilauryl tin catalyst, which was added in proportions of 1 to 3% obtained PUs from castor oil (Ricinus communis) and MDI (diphenyl methane diisocyanate). The materials were characterized by infrared spectroscopy (FTIR), nuclear magnetic resonance {sup 1}H NMR, thermogravimetry (TG) and derivative thermogravimetry (DTG). The reaction for obtaining the polyester was confirmed by FTIR, the absorption band between 1708-1730 cm{sup -1} and {sup 1}H NMR, in the region 1.4 to 1.8 ppm and 2.2 to 2.6 ppm. The thermal decomposition of polyester occurred with temperature above 300 ° C. PUs showed similar thermal stability. (author)

    Two 10 L completely mixed reactors operating at 37°C and 20 days SRT were used to evaluate the relationships between reactor performance and microbial community dynamics during anaerobic co-digestion of biodiesel waste glycerin (BWG) with municipal wastewater sludge (MWS). The addition of up to 1.35% (v/v) BWG to reactor feeds yielded increased VS and COD removal together with enhanced the biogas production and methane yield. This represented 50% of the MWS feed COD. Pyrosequencing analysis showed Methanosaeta (acetoclastic) and Methanomicrobium (hydrogenotrophic) to be the methanogenic genera present in greatest diversity during stable reactor operation. Methanosaeta sequences predominated at the lowest BWG loading while those of Methanomicrobium were present in greatest abundance at the higher BWG loadings. Genus Candidatus cloacamonas was present in the greatest number of bacterial sequences at all loadings. Alkalinity, pH, biogas production and methane yield declined and VFA concentrations (especially propionate) increased during the highest BWG loading.

    Crude glycerin is a by-product of biodiesel production and has recently become more available as a livestock feed with the growth of the biofuel industry. Two experiments were conducted to evaluate the use of crude glycerin (GLY) as a feed ingredient in steam-flaked corn (SFC)-based growing diets fed to beef cattle. In Exp. 1, crossbred steers (n = 50; initial BW = 282 ± 2 kg) were used to determine the effects of GLY when included at 0, 2.5, 5, 7.5, and 10% of DM in a growing diet on cattle performance. In Exp. 2, crossbred steers (n = 54; initial BW = 283 ± 1 kg) were used to determine the effects of replacing SFC (REPSFC) or alfalfa hay (REPAH) with 7.5% GLY or a control diet without GLY (CON) on growing steer performance. In Exp. 1, final BW tended to respond in a quadratic manner (P = 0.09) in which it increased from 0 to 7.5% GLY and decreased from 7.5 to 10% GLY. Dry matter intake did not differ (P > 0.23), yet ADG responded quadratically (P = 0.04), where it increased from 0 to 7.5% GLY and decreased from 7.5 to 10% GLY. Feed efficiency (G:F) decreased linearly (P = 0.05) with increasing GLY concentration. In Exp. 2, final BW was greater for steers fed REPAH than CON or REPSFC (P = 0.04). Steers fed REPAH had a greater ADG than CON or REPSFC (P = 0.04). When GLY replaced SFC, ADG increased from 0 to 7.5% GLY where it was maximized before decreasing from 7.5 to 10% GLY inclusion. Replacing 7.5% of alfalfa hay (AH) in a growing diet with GLY can be beneficial to animal performance, which is likely the result of GLY being greater in energy than AH.

    Our study was directed not only towards the diagnosis of small bowel Crohn's disease, but especially to a quantitative analysis, for a correct therapeutical approach. This experimental trial is based on the relationship between radiological evidence, measured during small bowel enema, and the seriousness of the morphological and functional damage to the intestinal mucosal membrane, evaluated with a post-heparin diamine-oxidase activity test. With this method we studied 35 selected patients; 16 of them were affected by the disease with an exclusive localization in the small bowel and 5 have been considered separately, because 3 patients had already been operated and the other 2 showed different localizations. In our results, the two parameters were not constantly related to each other. In other words the enema's morphological data sometimes do not accord with the mucosal membrane integrity index expressed by the enzyme. Anyway the importance of this study is the attempt of making an objective comparison between an anatomic situation and its functional consequence. These aspects have a great significance in Crohn's disease.

    Background. We wanted to evaluate the indication for ordering small bowel enema and whether specific clinical symptoms and signs are associated with the diagnostic yield. Material and methods. Medical charts and requisition slips for 241 patients examined with small bowel enema at Harstad Hospital from 1986 to 1995 were reviewed. Results. The most common symptom leading to small bowel radiography was pain, registered in almost three fourths of the patients, about one half reported diarrhoea. Elevated sedimentation rate and occult blood in the faeces were reported in one fourth of the patients. For a large proportion of the patients there was no information about adequate preliminary tests in the medical charts. Normal radiography was reported in three fourths of the patients. Lesions consistent with Crohn's disease were found in one of eight patients. No symptoms or signs except for elevated sedimentation rate, clearly indicate a positive diagnostic finding. Many requisition slips did not contain available information. Interpretation. Small bowel radiography is performed on wide indications. It is difficult to make a careful selection of patients based on reported symptoms and signs. However, some preliminary tests are helpful and should be done.

    Full Text Available After transesterification reaction, biodiesel and glycerin (the resulting co-product, coupled to reaction excesses and impurities, make up two distinct phases that must be separated. The use of ethanol as a transesterificating agent impairs the above-mentioned separation due to the greater affinity of ethyl esters (biodiesel from ethanol to glycerin. Current research provides an analysis of the influence of temperature on the rheology of biodiesel and the bio-diesel-glycerin-ethanol blend. Rheology behavior is highly important not merely in issues involving, for instance, discharging and pumping, but also as a factor that should be evaluated within the process of separation of the biodiesel-glycerin phases by decantation and centrifugation.

    Previous investigators have shown significant benefit using CO{sub 2} for bowel insufflation. Others have suggested that the long-acting smooth muscle relaxant, Mebeverine, may be of benefit. We subjected this to a randomised double-blind trial. A total of 181 outpatients were randomised to receive either Mebeverine or placebo as pre-medication, and either air or CO{sub 2} for bowel insufflation, thus creating four treatment groups. Visual-analogue lines were used to record pain scores before, during, and up to 8 h following the enema. All groups showed increased pain scores during the enema, with peak pain scores at the end of the examination, falling to baseline scores by 8 h. Patients receiving the combination of C0{sub 2} and placebo had significantly lower pain scores at 1 and 4 h (P=0.00 and P=0.014, respectively; Kruskal-Wallis test) compared with all other groups. Having Mebeverine as a pre-medication did not significantly lower pain scores compared with placebo, and decreased the amount of benefit received from the CO{sub 2}. We confirm that CO{sub 2} is of benefit in decreasing pain during barium enema, and we recommend its routine use to improve the comfort of patients. Mebeverine is not of benefit, and its use as a pre-medication for enemas is not recommended. (orig.)

    Full Text Available The effect of glycerin inclusion on the intake behavior of heifers was analyzed. During the 102-day experimental period, thirty-six 13-month old heifers, average initial weight 226±12 kg, were distributed in a completely randomized design with four treatments and nine replications: G0.0 = control, G2.8 = 2.8%, G6.1 = 6.1%, and G9.1 = 9.1% glycerin in DM intake. Intake behavior was undertaken by monitoring animal activities for 24 hours every five minutes. The inclusion of glycerin in the diet resulted in a linear decrease in grazing time, linear increase in idle time and quadratic effect on trough time. Moreover, glycerin inclusion did not affect the number of grazing and rumination periods. The number of idle periods showed a quadratic effect, whereas trough period decreased linearly with increasing glycerin. Glycerin did not affect grazing time and rumination period. Idle time increased linearly with increasing glycerin in the diets. Time had a quadratic effect and feeding and total chewing time showed a linear decrease with glycerin inclusion in the diets.O experimento foi realizado para estudar a inclusão de glicerina sobre o comportamento ingestivo de novilhas.

    In 2007, the United States Food and Drug Administration released guidance recommending testing of glycerin used in regulated consumer products, such as cough syrup preparations, toothpaste, and other pharmaceutical and food products, for the toxic compounds ethylene glycol and diethylene glycol. Regulatory laboratories routinely test glycerin, and products containing glycerin or related compounds for these toxic glycols, using an official gas chromatographic method, to ensure the safety of these products. The current work describes a companion technique to compliment this GC-FID method utilizing Orbitrap mass spectrometry with direct analysis in real time ionization to rapidly screen these samples qualitatively, with results in as little as five seconds, with no sample preparation required. This allows the more time and resource intensive method to be reserved for those rare cases when these compounds are detected, potentially greatly improving laboratory efficiency. The technique was evaluated for qualitative sensitivity and repeatability, and compared against the GC-FID method. The method appears to perform well against these metrics.

    Porous ethyl cellulose (EC) microspheres were prepared from the acetone-glycerin-water ternary system using an oil/water (O/W)-type emulsion solvent extraction method. The O/ W type emulsion was prepared using acetone dissolved ethyl cellulose as an oil phase and aqueous glycerin as a water phase. The effects of the different solvent extraction modes on the porosity of the microspheres were investigated. The specific surface area of the porous EC microspheres was estimated by the gas adsorption method. When the solvent was extracted rapidly by mixing the emulsion with water instantaneously, porous EC microspheres with a maximum specific surface area of 40.7±2.1 m2/g were obtained. On the other hand, when water was added gradually to the emulsion, the specific surface area of the fabricated microspheres decreased rapidly with an increase in the infusion period, with the area being 25-45% of the maximum value. The results of an analysis of the ternary phase diagram of the system suggested that the penetration of water and glycerin from the continuous phase to the dispersed phase before solidification affected the porosity of the fabricated EC microspheres.

    Herein we present an unusual phosphine-free method to fabricate water soluble CdSeS nanocrystals in cubic structure. In this method, glycerin was used as a stabilizing agent replacing tri-n-octylphosphine oxide (TOPO). Water solution of Na2SeO3 in polyethylene glycol was utilized as Se source. 3-Mercaptopropionic acid (MPA) provides S source. The phosphine-free Se and S sources were found to be highly reactive and suitable for the synthesis of CdSeS nanocrystals. XRD and HRTEM images confirm the formation of CdSeS nanocrystals in zinc blende structure. The absorption peaks on UV-vis spectra of as-prepared CdSeS nanocrystals are tunable from 330 nm to 440 nm, which blue shifts to shorter wavelength side in comparison with that of pure CdSe nanocrystals. The cubic CdSeS nanocrystals demonstrate narrow PL emissions spectra between 464 and 615 nm. Transmission electron microscopy images show the uniformity for the size distribution of the ternary QDs. Series water soluble CdSe(1-x)S(x) (x = 0:1) nanocrystals have also been synthesized using Na2SeO3 and Na2S solution as the Se-S co-sources. Tunable band gap energies of CdSe(1-x)S(x) (x = 0:1) nanocrystals upon chemical composition x have been achieved, the gap ranges from 290 nm to 558 nm.

    The aim of the present research work was to boost biogas production from cattle manure (CM) by adding food waste (FW) and crude glycerin (Gly) from the biodiesel industry as co-substrates. For this purpose, different quantities of FW and Gly were added to CM and co-digested in an induced bed reactor (IBR) at 55 °C. Sonication pre-treatment was implemented in the CM+Gly mixture, applying 550 kJ/kg TS to enhance the biodegradability of these co-substrates. The best results were obtained with mixtures of 87/10/3 (CM/FW/Gly) (w/w) operating at an organic loading rate of 7 g COD/L day, obtaining 92% COD removal, a specific methane yield of 640 L CH4/kg VS and a methane production rate of 2.6L CH4/L day. These results doubled those obtained in the co-digestion of CM and FW without the addition of Gly (330 L CH4/kg VS and 1.2L CH4/L day).

    Full Text Available Sodium beta-alumina is an efficient ion conducting solid electrolyte due to fast ionic conductivity arising from its favourable crystal structure. Other main requirements of a material to serve as solid electrolyte are fine grain structure, minimum porosity and good electrical properties at the operating temperature, which is usually about 300 °C. Mg-doped sodium beta-alumina powder was synthesized using citrate sol-gel route (wherein glycerine was used as a fuel and calcined at different temperatures (950–1100 °C. The synthesized powders have β′′-alumina as a dominant phase and particle size in range 75–95 nm. The obtained powders were compacted by uniaxial pressing at 100 MPa and sintered at 1500 °C for 3–10 h. Maximal density of the sintered samples was 92% TD and the primary phase was β′′-alumina. The highest conductivity of 0.38 S/cm was measured at 300 °C and the lowest activation energy for conduction of 0.20 eV was obtained.

Treatments diets contained 0%, 5%, 10%, and 20% of dietary DM of CGLY. Based on this experiment, there were no significant differences (p>0.05 among treatment groups regarding DM intake and digestion coefficients of nutrients (DM, OM, CP, EE, NDF, and ADF. Likewise, mean serum glucose, BHBA, and PCV concentrations were not affected (p>0.05 by dietary treatments, whereas serum insulin concentration linearly increased (L, p = 0.002 with increasing the amount of CGLY supplementation. Ruminal pH, NH3-N, and BUN concentration were unchanged by dietary treatments, except for 20% of CGLY, NH3-N, and BUN were lower (p<0.05 than for the diets 10% of CGLY, while the difference between the diets 0%, 5%, and 20% of CGLY were not significant. The amount of N absorption and retention were similar among treatments. Based on this study, CGLY levels up to 20% in total mixed ration could be efficiently utilized for goats and this study elucidates a good approach to exploiting the use of biodiesel production for goat production.

    Hydrophobic poly(hydroxyethyl methacrylate/glycerin) [poly(HEMA/GR)] gel with a three-dimensional (3D) framework was successfully fabricated and employed to integrate with polyaniline (PANi). The resultant poly(HEMA/GR)/PANi gel electrolyte exhibited interconnective porous structure for holding I{sup −}/I{sub 3}{sup −}, giving a similar conduction mechanism and ionic conductivity to that of liquid system but a much enhanced retention of I{sup −}/I{sub 3}{sup −} redox couple. Fourier transform infrared spectroscopy, X-ray diffraction patterns, cyclic voltammograms as well as electrochemical impedance spectroscopy were employed to evaluate the molecular structure, crystallinity, and the electrochemical behaviors, showing that the combination of PANi with poly(HEMA/GR) caused a lower charge-transfer resistance and higher electrocatalytic activity for the I{sub 3}{sup −}/I{sup −} redox reaction in the gel electrolyte. An efficiency of 6.63% was recorded from the quasi-solid-state DSSC assembled with the poly(HEMA/GR)/PANi gel electrolyte at 100 mW cm{sup −2}. - Graphical abstract: A poly(HEMA/GR)/PANi gel electrolyte is synthesized through in situ polymerization of PANi in 3D framework of poly(HEMA/GR) hydrophobic hydrogel. The recorded ionic conductivity and electrochemical performances are significantly enhanced by integrating with PANi The resultant overall photo-to-electric conversion efficiency is 6.63%. The high ionic conductivity, along with good electrolyte retention ability, reasonable DSSC performance, low cost, simple and scalable synthesis procedure, and competitive cost, promises the electrolyte to find applications in quasi-solid-state DSSCs. - Highlights: • Poly(HEMA/GR) was employed to combine with PANi in the 3D framework. • The conductivity and electrochemical performances were enhanced. • The conversion efficiency of the quasi-solid-state DSSC was 6.63%.

    This experiment was evaluation of the effects of increasing concentrations of crude glycerin from waste vegetable oil (CGWVO) in diets on feed intake, digestibility, ruminal fermentation characteristics, and nitrogen balance of goats. Four crossbred male (Thai Native × Anglo Nubian) goats, with an average initial body weight (BW) of 31.5 ± 1.90 kg, were randomly assigned according to a 4 × 4 Latin square design. The dietary treatments contained 0, 2, 4, and 6 % of dietary dry matter (DM) of CGWVO. Based on this experiment, there were significantly different (P > 0.05) among treatment groups regarding DM intake and digestion coefficients of nutrients (DM, OM, CP, EE, NDF, and ADF), which goats receiving 6 % of CGWVO had lower daily DMI and nutrient intake than those fed on 0, 2, and 4 % of CGWVO. Ruminal pH, NH3-N, and blood urea nitrogen (BUN) concentration were unchanged by dietary treatments, except that for 6 % of CGWVO supplementation, NH3-N, and BUN were lower (P absorption and retention were similar among treatments, except that for 6 % of CGWVO which N absorption was lower (P < 0.05) than among treatments while the difference between the diets 0, 2, and 4 % of CGWVO were not significant. Based on this study, CGWVO levels up to 4 % in total mixed ration could be efficiently utilized for goats. This study was a good approach in exploiting the use of biodiesel production from waste vegetable oil for goat production.

    Full Text Available A new technique was developed to make highly loaded (up to 95% formaldehyde free natural fiber boards. The purpose of the paper is to report a broad study on 85% kenaf boards using linear thermoplastic polymers as the binder in preparing the boards to determine if these materials have potential in commercial applications by comparing them to other commercial materials. In these materials, linear thermoplastic polymer chains act as an adhesive and the product resembles a typical wood based panel (e.g., phenol formaldehyde fiber board. The process involved the use of small amount of glycerine in the fiber to enhance processibility in a thermo-kinetic mixer followed by hot pressing. In this paper, we report the properties of 85% by weight kenaf fiber boards using polypropylene as the adhesive. A maleated polypropylene was used to improve the adhesion and stress transfer between the adhesive and kenaf fiber. The addition of 2% by weight of glycerine based on the dry weight of kenaf fiber resulted in the best properties of the boards. Differential scanning calorimetric studies suggested that the glycerine had a little effect on the percent crystallinity of the matrix. Dynamic mechanical tests of the 85% boards showed some differences compared to conventional 60% by weight kenaf-PP composites. The 85% kenaf boards had a flexural strength of 75 MPa and a flexural modulus of 6.8 GPa with a specific gravity of 1.24. These properties are comparable to standard formaldehyde free high density hardboards with flexural strengths of 48.3 MPa and flexural modulus of 5.5 GPa, and a specific gravity of 1.28. This paper gives a broad overview of an initial study of these new materials.

    X-ray examinations of the colon (barium enema) and the kidneys (IVU) are combined with rather high radiation doses to the patients when using analogue technique with film-screen systems. It is therefore of great interest to see if the change from analogue to digital technique involves a reduction of doses. Barium enema and IVU examinations were monitored with DAP-meters before and after the X-ray department changed to digital techniques. For IVU also the change from storage phosphor plates to a Direct Digital detector is included. The study comprises between 53 and 87 patients for each modality of the two examinations. A considerable dose reduction was observed. In barium enema the overview images with large field sizes were omitted when using digital technique. On the other hand the number of spot images was increased from 6 to 22. The fluoroscopy time was increased from 4 minutes to 6 minutes. The DAP value was reduced from 54,3 Gy cm sup 2 to 21,9 Gy cm sup 2. For IVU a dose reduction from 44,5 Gy cm sup 2...

    Twenty-three patients with attacks of distal ulcerative colitis were treated randomly with either 2 or 3 mg of topically administered beclomethasone dipropionate (BDP) or 30 mg of prednisolone sodium phosphate (PP). The effect of the steroid enemas on adrenocortical function was assessed by ACTH tests, which were performed before and after treatment. Endoscopic, clinical and histological scores were comparable in the three treatment groups in this pilot trial. Fasting cortisol in the PP group decreased significantly from 0.47 +/- 0.12 mumol/l before to 0.22 +/- 0.14 mumol/l (P less than 0.05) after therapy; in the BDP group no significant changes were found. Urinary cortisol excretion in the PP group was not detectable after therapy; in the BDP group no changes were found. It is concluded that in the topical treatment of ulcerative colitis, BDP may be preferable to PP because it exerts a promising anti-inflammatory action without affecting adrenocortical function.

    Despite numerous body moisturizers being available, cosmetic xerosis continues to be a leading skin problem for consumers. We performed two 35-day studies to evaluate the ability of a variety of body moisturizers containing various levels of oils/lipids, humectants, as well as other ingredients (e.g., niacinamide) to improve stratum corneum integrity. 63 and 58 female subjects were enrolled and randomized in an incomplete block design to six of nine products (eight moisturizers or no treatment control) in studies 1 and 2, respectively. The primary endpoints included visual dryness by a qualified skin grader, skin hydration as measured by Corneometer, and barrier integrity as measured by transepidermal water loss (TEWL). The primary comparisons for the two niacinamide/glycerin moisturizers were to the other six moisturizers and to the no treatment control for each endpoint. The two niacinamide/glycerin moisturizers demonstrated an overall better solution towards rapid and prolonged improvement of cosmetic xerosis due to functional improvement of stratum corneum barrier function compared to no treatment and the other moisturizers tested. These studies establish the benefit of including niacinamide in a body moisturizer to improve the integrity of the stratum corneum and thus reduce cosmetic xerosis over time.

    Expansion of the biodiesel industry has increased the glycerin (GLY) supply. Glycerin is an energy-dense feed that can be used in ruminant species; however, the energy value of GLY is not known. Therefore, the effects of GLY inclusion at 0, 5, 10, and 15% on energy balance in finishing cattle diets were evaluated in 8 steers (BW = 503 kg) using a replicated Latin square design. Data were analyzed with the fixed effects of dietary treatment and period, and the random effects of square and steer within square were included in the model. Contrast statements were used to separate linear and quadratic effects of GLY inclusion. Glycerin replaced dry-rolled corn (DRC) at 0, 5, 10, and 15% of dietary DM. Dry matter intake decreased linearly (P = 0.02) as GLY increased in the diet. As a proportion of GE intake, fecal energy loss tended to decrease linearly (P 0.31) as a proportion of GE as GLY increased in the diet. Methane energy loss as a proportion of GE intake tended to respond quadratically (P = 0.10), decreasing from 0 to 10% GLY inclusion and increasing thereafter. As a proportion of GE intake, ME tended to respond quadratically (P = 0.10), increasing from 0 to 10% GLY and then decreasing. As a proportion of GE intake, heat production increased linearly (P = 0.02) as GLY increased in the diet. Additionally, as a proportion of GE intake, retained energy (RE) tended to respond quadratically (P = 0.07), increasing from 0 to 10% GLY inclusion and decreasing thereafter. As a proportion of N intake, urinary and fecal N excretion increased linearly (P < 0.04) as GLY increased in the diet. Furthermore, grams of N retained and N retained as a percent of N intake both decreased linearly (P < 0.02) as GLY increased in the diet. Total DM digestibility tended (P < 0.10) to respond quadratically, increasing at a decreasing rate from 0 to 5% GLY inclusion. Overall, RE tended to decrease as GLY increased in the diet in conjunction with a decrease in N retention, which could indicate

    Building on a technical result by Brunnemann and Rideout on the spectrum of the Volume operator in Loop Quantum Gravity, we show that the dimension of the space of the quadrivalent states --with finite-volume individual nodes-- describing a region with total volume smaller than $V$, has \\emph{finite} dimension, bounded by $V \\log V$. This allows us to introduce the notion of "volume entropy": the von Neumann entropy associated to the measurement of volume.

    PURPOSE: The aim of the study was to evaluate the efficacy of a double-contrast barium enema (DCBE) with CO{sub 2} as a distending gas after a screening flexible sigmoidoscopy for reducing abdominal distension after an examination. PATIENTS AND METHODS: A total of 165 DCBEs for patients with positive faecal occult blood tests were randomly allocated to a CO{sub 2} group (n = 83) and a control group (n = 82) using air. Abdominal radiograph were taken before the DCBE, immediately following it, and 30 minutes later to determine residual bowel gas. The degree of abdominal discomfort was recorded using a scoring system. RESULTS: The patients in the CO{sub 2} group had significantly smaller amounts of residual gas 30 minutes after the DCBE than did the control group, both in the colon (P < 0.02) and in the small intestine (P < 0.001). There was significantly less abdominal distension after the DCBE in the CO{sub 2} group compared to the control group (P < 0.001). The abdominal discomfort score at 30 minutes after CO{sub 2} correlated with the residual gas in the small intestine(r = 0.390,P = 0.003) but not in the colon(r = 0.155, P 0.15). The quality of the images and the number of polyps detected did not differ between two groups. CONCLUSIONS: We concluded that using CO{sub 2} when administering a DCBE after a screening sigmoidoscopy was useful for relieving abdominal discomfort following the examination; furthermore, it did not impair the diagnostic ability of the DCBE.

    AIM: To assess inter-observer error for the diagnosis of neoplasia on double contrast barium enema (DCBE) in the light of claims that no additional interpretative training would be needed for implementation in a national screening programme. MATERIALS AND METHODS: 10 experts, 10 consultants, and 10 experienced trainees each reported 20 DCBE studies, of which two showed cancer, three showed large polyps, four showed small polyps, and 12 were normal. Inter-observer variation was compared using odds ratios with the trainee group as reference (baseline group). RESULTS: Experts were significantly more likely to correctly identify neoplasia on DCBE than trainees. The odds of a correct diagnosis for experts were 2.79 (95% CI 2.04, 3.81) for cancer, 2.36 (1.88, 2.97) for large polyps, and 3.50 (1.98, 6.18) for small polyps. While consultants were more likely to correctly diagnose a large polyp than trainees, 1.45 (1.15, 1.84), there was no significant difference between these two groups for the correct diagnosis of either cancer, 1.24 (0.52, 2.96), or small polyps, 1.26 (0.83, 1.90). A cancer was missed by 6 (60%) experts, 9 (90%) consultants, and 8 (80%) trainees. Large polyps were missed by 4 (40%) experts, 5 (50%) consultants, and 6 (60%) trainees. There was no significant difference between any group when false positive diagnoses were considered. CONCLUSIONS: There is considerable inter-observer perceptive error for the diagnosis of neoplasia on DCBE. Experts performed significantly better than other observers but the overall standard of performance was poor, even amongst experts.

The major findings are as follows: the high contrast barium-filled colon can be readily recognized among intestinal loops of different contrasty in the abdomen on the film. It is easy to make a differential diagnosi between a complete mechanical obstruction and a paralytic ileus. With the former, the contrast between a smaller gas-free colon and the gas-distended bigger small intestine with fluid-levels will be seen on the film;while with the latter, a gas-disteuded colon with barium-levels should be present on the film:Among the small intestines, the prestence of "coffee bean sign", "concentric loop" shadow, long air-fluid-level in a hypotonic loop, and the presence of peritoneal fluid should call attention to the possible strangulation of the intestine. Some of the primary causes of intestinal obstruction can also be shown on the film by using barium enema, such as the specific "cupping" shadow in intussusception, widening of interloop opacity in necrotic enteritis, microcolon in intestinal atresia of newborn, and spastic colon segment in Hirschsprung's disease. Methods, indications and contraindications of the use of barium enema are discussed in detail in the text.

    Forty-eight individually fed crossbred steers (initial BW = 381 ± 7.61 kg) were used to determine the effects of glycerin (GLY) concentration in steam-flaked corn (SFC)-based diets with added yellow grease on animal performance and carcass characteristics. Glycerin was included at 0, 2.5, 5, and 10% dietary DM replacing SFC. A completely randomized design was used with steers as the experimental unit, and the model included the fixed effects of diet. Contrast statements were used to determine linear and quadratic effects of GLY inclusion. Final BW and DMI were not affected (P > 0.27) by GLY concentration. Average daily gain and G:F based on live BW did not differ as GLY level increased in the diet from 0 to 10% of DM (P > 0.33). Carcass-adjusted final BW and carcass-adjusted G:F were also not affected by GLY concentration (P > 0.22); however, carcass-adjusted ADG tended to respond quadratically by decreasing from 2.5 to 5% GLY inclusion and increasing thereafter (P = 0.10). Calculated dietary NEm and NEg did not differ as GLY increased in the diet (P > 0.37). Hot carcass weight tended to respond quadratically, decreasing from 2.5 to 5% GLY and increasing thereafter (P = 0.10). Likewise, dressing percentage tended to respond quadratically by decreasing from 2.5 to 5% GLY inclusion and increasing to 10% GLY inclusion (P = 0.09). Fat thickness decreased linearly as GLY inclusion increased in the diet (P 0.21). Calculated yield grade (YG) decreased linearly as GLY increased in the diet from 0 to 10% of DM (P = 0.04). Based on our results, there was no animal performance benefit for replacing SFC with GLY in diets containing yellow grease, and the only change in carcass merit was a slight improvement in YG.

    Objective To analyze the different success rates of air enema in intussusception cases at different ages and evaluate the value of plain film in assessing the pathogenetic condition of intussusception and intussusception with vascular compromise in children. Methods A retrospective analysis was performed on the success rates of air enema in 1119 pediatric cases of intussusception at different ages. The radiographic findings of 190 cases were analyzed. Air enema reduction failed in 95 cases. And 95 control cases were randomly selected for reduction by air enema. Their operative and pathological data were analyzed and compared with the findings of plain film. Intestinal obstruction with vascular compromise was analyzed by a comparison of plain film and pathology. The plain films of patients were analyzed by two experienced radiologist independently. Whenever there was dissension, they discussed and reached an agreement. Results In all cases of intussusception, the successful reduction rate was 91.5%. The cases within l-year-old were 627 cases, air enema success rate was 87.1% and the success rate of air enema was 97.2% in beyond 1-year-old group. There was significant difference between two groups (x2 = 36. 01, P <0. 01). In 95 cases of failed air enema reduction, 14 cases were ileoileal, 10 ileocaecal and 25 ileocolic.And 44 cases were ileoilealcolic and 2 ileocoliccolic. Eleven cases had intestinal necrosis. Four cases had small bowel duplication cyst and 3 with Meckel's diverticulum. Intestinal obstruction with vascular compromise in plain film had a high concordance with pathology (kappa = 0. 7128). The pathology type was somewhat correlated with the finding of plain film (P < 0. 01). As assessed by plain film, there were intussusceptions with vascular compromise (n = 30) with a coffee-bean sign or banana sign, a paucity of bowel gas (n = 36), quadrant gas (n = 51) and mass or crescent (n = 73). Through an analysis between plain film signs and the onset of

    We determine the results and complications of continent urinary diversion and simultaneous Malone antegrade continent enema (MACE) and the Mitrofanoff principle using the divided appendix, and report on the VQQ and VQ technique for prevention of complications at the stoma level. Between June 1995 and June 1999, 40 patients 4 to 22 years old (mean age 9.5) underwent Mitrofanoff procedures in conjunction with the MACE and augmentation cystoplasty as primary (5) or salvage (35) therapy. Of the patients 35 had neuropathic bladder, and 5 had bladder and bowel dysfunction without detectable neurological abnormalities. All patients had an antireflux Mitrofanoff channel constructed using distal part of the appendix with its divided mesothelium. The proximal half of the appendix was preserved as a modified MACE. Average length of appendix was 10.3 cm. (range 9 to 15) and no correlation was found between the length of appendix and age of child. The stoma construction was performed as 2 different techniques. The 2 appendix stomas were initially anastomosed with 2 separate triangular posterior V shape skin flaps on the right lower abdominal wall. Both appendix mucosae were completely buried with a single or double quadrilateral skin flap (VQQ and VQ technique). All patients are continent day and night without diapers. Mean followup was 22 months (range 8 to 48) and the overall incidence of complications was 7.5%. Mitrofanoff stomal stenosis due to catheter false passage occurred postoperatively in 1 case, gas leakage from the MACE in 1 and partial mucosal prolapse in 1. The MACE and Mitrofanoff principle have proved invaluable for the treatment of children with urinary and fecal incontinence. The divided appendix with 2 separate mesotheliums is an ideal channel for simultaneous Mitrofanoff and MACE when the appendix length is 9 cm. or more with a suitable branching mesothelium. When the appendix is short we prefer to use it as the Mitrofanoff and create a pediculed tube flap

    Full Text Available The objective of this study was to evaluate the ingestive behavior of lactating dairy cows grazing on tropical pasture supplemented with different levels of crude glycerin in the diet. Ten lactating cows, ¾ Gir x ¼ Holstein Dairy cows, primiparous, and 109 ± 24 days of lactation, mean age 30 ± 6 months and mean body weight of 426.2 ± 68.29 kg, distributed into five treatments, in double (5x5 Latin square design, were used. The treatments consisted of inclusion levels of crude glycerin in the diet (0.0, 4.5, 9.0, 13.5, and 18.0% dry matter basis. The behavior evaluation was performed on the 14th day of each period, with observations every five minutes for a period of 24 hours. The results were analyzed statistically using analysis of variance and regression at 5% probability. For the grazing time, other activities, rumination, feeding trough, the number of grazing periods, other activities, rumination and feeding trough, as well as bit rate, number and time of chews per bolus, and efficiencies of eating and ruminating were not significant differences among crude glycerin levels in the diet (P>0.05. The inclusion of crude glycerin in diets for lactating cows in tropical pastures does not promote changes in ingestive behavior. The absence of negative effects related to the use of this byproduct in substitution of corn in these conditions allows its use in up to 18% crude glycerin in diets for dairy cows without changing the behavioral parameters related to food intake.

    Additives are added to the electrodeposition of metal coatings to improve the characteristics of the deposit. However, the objective was to investigate the effect of adding glycerin and formic acid in the deposition efficiency and deposit structure of zinc-nickel alloy obtained by electrodeposition. The depositions were made at a galvanostatic current density of 10 mA/cm{sup 2} to obtain a deposit of about 5 mm in thickness. The deposition efficiency was determined through measures of mass, chemical composition of the deposit in the presence and absence of additives was examined by X-ray Spectrometer Fluorescence (XRF) and surface characterization of coatings was performed by Scanning Electron Microscopy (SEM). The high levels of glycerin (0,07 M) and formic acid (0,26 M) in bath deposition increased the deposition efficiency of around 10% to 12% by mass, respectively. (author)

    One experiment was conducted to evaluate the influence of glycerin (GLY) on animal performance and health when used as a partial replacement for roughage in receiving diets. The second experiment was conducted using ruminally and duodenally cannulated steers in a 4 × 4 Latin square to determine the site of nutrient digestion and ruminal fermentation characteristics when GLY replaced roughage at 0%, 2.5%, 5%, and 10% of diet DM. In Exp. 1, steers (initial BW = 245 ± 2.3 kg) were fed treatment diets over a 42-d period that consisted of a control diet based on steam-flaked corn with GLY inclusion in replacement of dietary roughage at 0%, 5%, and 10% of diet DM. A linear reduction in DMI was observed as GLY increased (P = 0.01). Glycerin incorporation tended to improve G:F in a linear manner (P = 0.07); efficiency was improved 5.4% and 4.7% at 5% and 10% GLY. The number of animals receiving treatment for bovine respiratory disease did not differ among treatments. Furthermore, there were no differences among treatments for mortality or the frequency of steers that were seropositive for serum antibody titers to infectious bovine rhinotracheitis on d 28. In Exp. 2, apparent OM and apparent and true starch digestibility increased linearly (P < 0.05) as GLY concentration increased, whereas true OM digestibility responded in a quadratic (P < 0.01) manner. Bacterial OM and bacterial starch flow responded quadratically (P ≤ 0.02), and flow increased from 0% to 5% GLY inclusion and decreased thereafter. Feed OM flow responded quadratically (P ≤ 0.05), where it decreased from 0% to 2.5% GLY and increased from 2.5% to 10% GLY inclusion. Feed starch (P = 0.02) and total starch (P = 0.02) flow from the duodenum decreased linearly as the concentration of GLY increased in the diet. Bacterial N flow to the duodenum responded quadratically (P < 0.01); it increased with increasing GLY in the diet up to 5% and then decreased from 5% to 10%. The acetate to propionate (A:P) ratio in

    Full Text Available PURPOSE: To evaluate the antioxidant effects of enemas containing aqueous extract of Ilex paraguariensis, comparing segments with and without fecal stream and correlating the segments with the duration of intervention. METHODS: Twenty-six Wistar rats were subjected to a diversion of the fecal stream in the left colon by a proximal colostomy and distal mucosal fistula. The rats were distributed randomly into two experimental groups of 13 animals each based on the time of sacrifice after surgical procedure (two or four weeks. Each group was then divided into two experimental subgroups that received either second daily enemas containing 0.9% saline solution or aqueous extract of Ilex paraguariensis at 0.2g/100g. Colitis was diagnosed by histopathological analysis and the detection of oxidative tissue damage by measuring the levels of malondialdehyde. The Mann-Whitney test was used to compare the tissue levels of malondialdehyde between colon segments with and without fecal stream in each experimental group, and the Kruskal-Wallis test was used to verify the variance between the levels of oxidative stress according the duration of the irrigation; both tests determined significance at 5% (pOBJETIVO: Avaliar os efeitos antioxidantes de clisteres contendo extrato aquoso de Ilex paraguariensis comparando segmentos com e sem trânsito fecal e correlacionando com o tempo de intervenção.

    .18 [0.43], negative predictive value 0.97 [0.96], positive likelihood ratio result 1.6 [5.63], negative likelihood ratio result 0.27 [0.29], kappa 0.31 [0.43]. Tumour prevalence was 12%. A graph of conditional probabilities was generated and analysed. A variety of unsuspected pathology was also found in this series of patients. CONCLUSIONS: MPCT should be double-reported, at least initially. 'Possible' lesions should be ignored. Analysis of the graph of conditional probability applied to a group of frail, elderly patients with a high mortality from all causes (33% in our study) suggests: (1) if MPCT suggests definite or probable carcinoma, regardless of the pre-test probability, the post-test probability is high enough to warrant further action, (2) frail, elderly patients with a low pre-test probability for CRC and a negative MPCT should not have further investigation, (3) frail, elderly patients with a higher pre-test probability of CRC (such as those presenting with rectal bleeding) and a negative MPCT should have either double contrast barium enema (DCBE) or colonoscopy as further investigations or be followed clinically for 3-6 months. MPCT was acceptable to patients and clinicians and may reveal significant extra-colonic pathology.

    Full Text Available Twelve ruminally cannulated steers (401.0 ± 41.5 kg and 24 mo were used in a replicated arrangement truncated Latin Square with six animals in six treatments and four periods to evaluate the effect of crude glycerine (CG; 80.3% of glycerol with starch or fiber-based energy ingredients in the concentrate on DMI, DM (DMD and NDF digestibility (NDFD and ruminal parameters. Experimental periods were 19 days (14 days for adaptation and 5 days to sampling. Diets were: CO - without CG and corn as ingredient of concentrate; CGC - inclusion of CG (10% of DM with corn in the concentrate; and CGSH - inclusion of CG (10% of DM with soybean hulls (SH in the concentrate. All three diets were offered at low (LC or high (HC concentrate level, CL (40 or 60%. Animals fed LC or HC diets had similar DMI, DMD and NDFD. Animals fed diets with CG associated with corn or SH had higher propionate concentrations and lower A:P ratio. Diets with HC increase the propionate but do not affect the NDFD. CG (10% of DM can be used to replace corn or SH in diets with 40 or 60% of concentrate, without affect NDFD.

    Carcass and meat quality traits of 60 Nellore young bulls fed diets without crude glycerin (CG); with CG replacing corn (CGc; 10% of dry matter - DM) in the concentrate; and with CG replacing soybean hull (CGsh; 10% of DM) in the concentrate were evaluated. Diets were evaluated at two concentrate levels (CLs). The CL did not affect cold carcass weight (CCW; P=0.6074), cold carcass dressing (CCD; P=0.9636), rib fat thickness (RFT; P=0.8696) and longissimus muscle area (LMA; P=0.7524). Animals fed diets with CGc or CGsh showed meat with greater deposition of monounsaturated fatty acid (MUFA; P=0.0022) and CLA (18:2 cis-9, trans-11) contents (P=0.0001) than animals fed diets without CG. The inclusion of 10% of CG in diets CGc or CGsh does not affect the carcass and meat quality traits; however, it increases the MUFA and CLA contents in beef, although these changes are very small in nutritional terms.

    The effects of aeration and agitation on the properties and production of xanthan gum from crude glycerin biodiesel (CGB) by Xanthomonas campestris mangiferaeindicae 2103 were investigated and optimized using a response surface methodology. The xanthan gum was produced from CGB in a bioreactor at 28 °C for 120 h. Optimization procedures indicated that 0.97 vvm at 497.76 rpm resulted in a xanthan gum production of 5.59 g L(-1) and 1.05 vvm at 484.75 rpm maximized the biomass to 3.26 g L(-1). Moreover, the combination of 1.05 vvm at 499.40 rpm maximized the viscosity of xanthan at 0.5% (m/v), 25 °C, and 25 s(-1) (255.40 mPa s). The other responses did not generate predictive models. Low agitation contributed to the increase of xanthan gum production, biomass, viscosity, molecular mass, and the pyruvic acid concentration. Increases in the agitation contributed to the formation of xanthan gum with high mannose concentration. Decreases in the aeration contributed to the xanthan gum production and the formation of biopolymer with high mannose and glucose concentrations. Increases in aeration contributed to increased biomass, viscosity, and formation of xanthan gum with greater resistance to thermal degradation. Overall, aeration and agitation of CGB fermentation significantly influenced the production of xanthan gum and its properties.

    Full Text Available Introduction: Intravenous therapy is indicated for many reasons. A significant number of patients admitted into hospital receive some forms of intravenous therapy through peripheral venous cannula, which is a common procedure carried out in hospital to allow rapid and accurate administration of medication. However, the intravenous cannulation can have undesirable effects, the most of which is phlebitis, which is due to mechanical, chemical or infectious cause. Method: In this study quasi-experimental research approach was used. Non probability purposive sampling technique was used to select the sample from the selected hospital. The research design adopted for the study was pre-test, post-test control group design. In the present study a sample of 60 hospitalised patients and who met the inclusion criteria was selected from the target population. In this study the instruments used are baseline Performa, structured interview schedule to assess the subjective symptoms and observation scale to observe the objective symptoms. Result: In experimental group post test mean score 1.10, SD was 0.71 respectively. In control group post test mean score 2.53, SD was 0.78 respectively. The obtained value 7.454 statistically was significant at 0.001 levels. So research hypothesis was accepted. So there was significant difference between post intervention phlebitis among the experimental group and control group. Discussion: In the research study findings revealed that Glycerin Magnesium sulphate dressing is highly effective in decrease phlebitis level to the patients.

    This study evaluated the influence of the applied volumetric organic load on biohydrogen production in an anaerobic sequencing batch biofilm reactor (AnSBBR) with 3.5 L of liquid medium and treating 1.5 L of glycerin-based wastewater per cycle at 30 °C. Six applied volumetric organic loads (AVOLCT) were generated from the combination of cycle periods (3 and 4 h) and influent concentrations (3000, 4000, and 5000 mg chemical oxygen demand (COD) L(-1)), with values ranging from 7565 to 16,216 mg COD L(-1) day(-1). No clear relationship was found between the applied volumetric organic load and the hydrogen production. However, the highest hydrogen molar production (MPr 67.5 mol H2 m(-3) day(-1)) was reached when the reactor was operated with a cycle period of 4 h and an influent concentration of 5000 mg COD L(-1) (AVOLCT 12,911 mg COD L(-1) day(-1)). This condition also reached the highest molar yield per applied load based on the organic matter (MYALC,m 21.1 mol H2 kg COD(-1)). In addition, the pretreatment of the sludge/inoculum was found to not influence the productivity/yield of the process, and the use of crude glycerol as a sole source of carbon exhibited a clear disadvantage for hydrogen production compared to pure glycerol. The AnSBBR used for the hydrogen production experiments operated with pure glycerol as a sole carbon source exhibited important practical potential.

    To study the effect of glycerin fatty acid ester (Poem TR-FB) concentrations on the dissolution rate of acetaminophen (APAP), the dissolution and disintegration behaviors of APAP tablets formulated using various lubricants were examined. The change over time in the available surface area of APAP (S(t)), which is in direct contact with solvent, was also analyzed using these dissolution data. In the dissolution tests, a retarded dissolution of APAP was not observed with TR-FB, whereas magnesium stearate (Mg-St), which is widely used as a lubricant, retarded the dissolution. However, no significant difference in the disintegration time between the two lubricants was observed. With regard to the time course of the S(t), Mg-St at 0.1% gave a maximum surface area value at 9.19 min (peak time); however, the profiles for APAP with Mg-St at greater than 0.5% showed downward curvature indicating a gradual decrease in surface area over time. Conversely, with TR-FB, even when its concentration was increased, the S(t) profile for APAP had a maximum value that was more than twice that of APAP with that of 0.5-3.0% of Mg-St. Scanning electron microscopy (SEM) observations showed that the differences in the dissolution rate and S(t) patterns between Mg-St and TR-FB could be explained by differences in extensibility deriving from their morphology. Therefore, it was concluded that TR-FB does not cause retardation of drug dissolution and may prove to be a superior alternative lubricant to Mg-St. Copyright © 2011 Elsevier B.V.

  11. Co-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane Production

    2009-01-01

    Full Text Available Problem statement: Refined Glycerin Wash Water (RGWW from the oleochemical industry contains high Chemical Oxygen Demand (COD and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME for its treatment and methane recovery. Approach: A large 500 m3 semi-commercial closed digester tank was used to study the effect of co-digesting POME and RGWW under mesophilic condition at different RGWW percentage. The digester performance in terms of COD removal efficiency and methane production rate and stability based on total Volatile Fatty Acids (VFA accumulation, Mixed Liquor Volatile Suspended Solid (MLVSS and pH were evaluated. Results: At 1.0% of RGWW co-digested, both COD removal efficiency and methane production rate showed satisfactory results with higher than 90% and 505 m3 day-1, respectively. However, once the percentage was increased to a maximum of 5.25%, COD removal efficiency remains high but the methane production rate reduced significantly down to 307 m3 day-1. At this stage, the digester was already unstable with high total VFA recorded of 913 mg L-1 and low cells concentration of 8.58 g L-1. This was probably due to the effect of plasmolysis on the methanogens at high concentration of NaCl in the digester of nearly 4000 mg L-1. Conclusion: Co-digesting of RGWW with high NaCl content and POME is satisfactory for COD removal but not for increasing the methane production.

    2017-09-01

    We develop a universal distributional calculus for regulated volumes of metrics that are suitably singular along hypersurfaces. When the hypersurface is a conformal infinity we give simple integrated distribution expressions for the divergences and anomaly of the regulated volume functional valid for any choice of regulator. For closed hypersurfaces or conformally compact geometries, methods from a previously developed boundary calculus for conformally compact manifolds can be applied to give explicit holographic formulæ for the divergences and anomaly expressed as hypersurface integrals over local quantities (the method also extends to non-closed hypersurfaces). The resulting anomaly does not depend on any particular choice of regulator, while the regulator dependence of the divergences is precisely captured by these formulæ. Conformal hypersurface invariants can be studied by demanding that the singular metric obey, smoothly and formally to a suitable order, a Yamabe type problem with boundary data along the conformal infinity. We prove that the volume anomaly for these singular Yamabe solutions is a conformally invariant integral of a local Q-curvature that generalizes the Branson Q-curvature by including data of the embedding. In each dimension this canonically defines a higher dimensional generalization of the Willmore energy/rigid string action. Recently, Graham proved that the first variation of the volume anomaly recovers the density obstructing smooth solutions to this singular Yamabe problem; we give a new proof of this result employing our boundary calculus. Physical applications of our results include studies of quantum corrections to entanglement entropies.

    Full Text Available Com a crescente produção de biodiesel no Brasil, aumenta também a produção de glicerina, co-produto dessa indústria. O principal componente da glicerina é o glicerol, altamente energético e, por isso, ela já vem sendo usada como alimento animal em vários países. O objetivo deste trabalho foi avaliar a composição química da glicerina produzida por indústrias de biodiesel no Brasil e discutir seu potencial de utilização na alimentação animal. Dezesseis usinas, responsáveis por 85,1% do biodiesel produzido no país, forneceram 41 amostras para análise. Cromo, cádmio e chumbo não foram detectados em nenhuma das amostras estudadas. Apenas quatro usinas, responsáveis por 36,8% da produção, produzem glicerina que atendem os parâmetros estabelecidos pelo Ministério da Agricultura, Pecuária e Abastecimento para os teores de umidade e glicerol. Apenas uma usina, responsável por 14,1% da produção, produz glicerina apta para uso na alimentação de ruminantes, por não utilizar sebo bovino como matéria prima para o biodiesel.The increasing production of biodiesel in Brazil also increases glycerin production, a co-product of this industry.

    The influence of source and level of inclusion of raw glycerin (GLYC) in the diet on growth performance, digestive traits, total tract apparent retention (TTAR), and apparent ileal digestibility of nutrients was studied in broilers from 1 to 21 d of age. There was a control diet based on corn and soybean meal and 8 additional diets that formed a 2 × 4 factorial with 2 sources of GLYC and 4 levels of inclusion (2.5, 5.0, 7.5, and 10%). The GLYC used were obtained from the same original batch of soy oil that was dried under different processing conditions and contained 87.5 or 81.6% glycerol, respectively. Type of processing of the GLYC did not affect any of the variables studied except DM and organic matter retention (P < 0.05) that was higher for the 87.5% glycerol diet. From d 1 to 21, feed conversion ratio (FCR) improved linearly (L, P ≤ 0.01) as the GLYC content of the diet increased, but ADG was not affected. On d 21, the relative weight (% BW) of the liver and the digestive tract increased (L, P < 0.01) as the level of GLYC in the diet increased, but lipid concentration in the liver was not affected. The TTAR of DM and organic matter increased quadratically (Q, P < 0.05) and the AME(n) content of the diet increased linearly (L, P < 0.01) with increases in dietary GLYC. Also, the apparent ileal digestibility of DM (L, P < 0.05; Q, P = 0.07) and gross energy (L, P < 0.01) increased as the GLYC content of the diet increased. It is concluded that raw GLYC from the biodiesel industry can be used efficiently, up to 10% of the diet, as a source of energy for broilers from 1 to 21 d of age and that the energy content of well-processed raw GLYC depends primarily on its glycerol content.

  6. Renormalized Volume

    For any conformally compact manifold with hypersurface boundary we define a canonical renormalized volume functional and compute an explicit, holographic formula for the corresponding anomaly. For the special case of asymptotically Einstein manifolds, our method recovers the known results. The anomaly does not depend on any particular choice of regulator, but the coefficients of divergences do. We give explicit formulae for these divergences valid for any choice of regulating hypersurface; these should be relevant to recent studies of quantum corrections to entanglement entropies. The anomaly is expressed as a conformally invariant integral of a local Q-curvature that generalizes the Branson Q-curvature by including data of the embedding. In each dimension this canonically defines a higher dimensional generalization of the Willmore energy/rigid string action. We show that the variation of these energy functionals is exactly the obstruction to solving a singular Yamabe type problem with boundary data along the...

    Objective] To observe effect to micro-inflammation state in experimental chronic renal failure (CRF) rats treated with TCM enema and explore it's mechanism. [Methods] The 44 SD male rats were randomly divided into normal control group, model control group, enema group and simvastatin group. All rats were 5/6 nephrectomy surgery to become CRF animal models except normal control group. After model establishment, each group began to fill the stomach or enema for 6 weeks. The blood serum creatinine (SCr), blood urea nitrogen (BUN), triglyceride (TG), C reactive protein (CRP), transforming growth factor alpha (TNF-α), and toll like receptor 4 (TLR4) were detected respectively at 1, 3, 6 weeks in each group, Animals were sacrificed at the end of the experiment to observe the morphologi-cal change of kidney and small intestine. [Results] The concentration of CRP and TNF-α were no statistical difference between enema group and simvastatin group. It suggested that the function of TCM enema was also similar to the role of statins in improving the micro-in-flammatory state, and its mechanism may be related to blocking the expression of TLR4. Pathological results showed that enema group has a certain improving effect on renal interstitial fibrosis. [Conclusion] TCM enema can improve the CRF rat survival state, delay the progress of the disease, and have certain positive effect on renal interstitial fibrosis. The mechanism of action of TCM enema may relate to reducing inflammation factor expression, improve micro-inflammation state function. The function of TCM enema is similar to simvastatin.%[目的]观察中药灌肠改善慢肾衰模型大鼠的微炎症状态情况,探讨其机制。[方法]将44只 SD 雄性大鼠随机分为正常对照组、模型对照组、灌肠方组和辛伐他汀组,除正除对照组外均行5/6肾切除术制作 CRF 动物模型。造模后各组开始灌胃或灌肠给药6周。分别于造模后1、3、6周取血检测大鼠的血肌酐

    Purpose: To evaluate the efficacy of sodium butyrate enemas (NABUREN) in prostate cancer radiation therapy (RT) in reducing the incidence, severity, and duration of acute RT-induced proctitis. Methods and Materials: 166 patients, randomly allocated to 1 of 4 groups (rectal sodium butyrate 1 g, 2 g, or 4 g daily or placebo), were treated with NABUREN during and 2 weeks after RT. The grade of proctitis was registered in a daily diary. The correlation between NABUREN and proctitis was investigated through χ{sup 2} statistics. The toxicity endpoints considered were as follows: total number of days with grade ≥1 proctitis (≥G1); total number of days with grade ≥2 proctitis (≥G2); ≥G1 and ≥G2 proctitis lasting at least 3 and 5 consecutive days starting from week 4 (≥G1+3d, ≥G2+3d); damaging effects of RT on rectal mucosa as measured by endoscopy. The relationship between endpoints and pretreatment morbidities, hormonal therapy, presence of diabetes or hypertension, abdominal surgery, or hemorrhoids was investigated by univariate analysis. Results: The patients were randomly allocated to the 4 arms. No difference in the distribution of comorbidities among the arms was observed (P>.09). The mean ≥G1 and ≥G2 proctitis were 7.8 and 4.9 for placebo and 8.9 and 4.7 for the NABUREN group, respectively. No favorable trend in reduction of incidence, severity, and duration of ≥G1 and ≥G2 proctitis was observed with NABUREN use. In univariate analysis, ≥G1+3d toxicity was found to be related to hemorrhoids (P=.008), and a slight correlation was found between ≥G2 proctitis and hormonal therapy (P=.06). The RT effects on rectal mucosa as based on endoscopic assessment were mainly related to diabetes (P<.01). Endoscopy data at 6 week showed no significant difference between the placebo and butyrate arms. The other investigated endpoints were not correlated with any of the clinical risk factors analyzed. Conclusion: There was no evidence of efficacy

However, some topical hydrating products could have negative effects on skin barrier function. In addition, hydrating effects of moisturizers are not commonly evaluated up to 24 hours after a single application. Hyaluronic acid (HA and glycerin are very well-known substances able to improve skin hydration. Centella asiatica extract (CAE could exert lenitive, anti-inflammatory and reepithelialization actions. Furthermore, CAE could inhibit hyaluronidase enzyme activity, therefore prolonging the effect of HA. A fluid containing HA 1%, glycerin 5% and stem cells CAE has been recently developed (Jaluronius CS [JCS] fluid. Study aim: To evaluate and compare the 24-hour effects of JCS fluid on skin hydration and on transepidermal water loss (TEWL in healthy subjects in comparison with the control site. Subjects and methods: Twenty healthy women, mean age 40 years, were enrolled in an intra-subject (right vs left, randomized, assessor-blinded, controlled, 1-day trial. The primary end points were the skin hydration and TEWL, evaluated at the volar surface of the forearm and in standardized conditions (temperature- and humidity-controlled room: 23°C and 30% of humidity using a corneometer and a vapometer device at baseline, 1, 8 and 24 hours after JCS fluid application. Measurements were performed by an operator blinded for the treatments. Results: Skin hydration after 24 hours was significantly higher (P=0.001; Mann–Whitney U test in the JCS-treated area in comparison with the control site. JCS induced a significant (P=0.0001 increase in skin hydration at each evaluation time (+59% after 1 hour, +48% after 8 hours and +29% after 24 hours in comparison with both baseline (P=0.0001 and non-treated control site (P=0

    Purpose: A previous, unblinded study demonstrated that an alcohol-free barrier film containing an acrylate terpolymer (ATP) was effective in reducing skin reactions compared with a 10% glycerine cream (sorbolene). The different appearances of these products precluded a blinded comparison. To test the acrylate terpolymer principle in a double-blinded manner required the use of an alternative cream formulation, a moisturizing durable barrier cream (MDBC); the study was conducted by the Trans Tasman Radiation Oncology Group (TROG) as protocol 04.01. Methods and Materials: A total of 333 patients were randomized; 1 patient was ineligible and 14 patients withdrew or had less than 7 weeks' observations, leaving 318 for analysis. The chest wall was divided into medial and lateral compartments, and patients were randomized to have MDBC applied daily to the medial or lateral compartment and sorbolene to the other compartment. Weekly observations, photographs, and symptom scores (pain and pruritus) were collected to week 12 or resolution of skin reactions if earlier. Skin dose was confirmed by centrally calibrated thermoluminescent dosimeters. Results: Rates of medial and lateral compartment Common Toxicity Criteria (CTC), version 3, greater than or equal to grade 3 skin reactions were 23% and 41%, but rates by skin care product were identical at 32%. There was no significant difference between MDBC and sorbolene in the primary endpoint of peak skin reactions or secondary endpoints of area-under-the-curve skin reaction scores. Conclusions: The MDBC did not reduce the peak skin reaction compared to sorbolene. It is possible that this is related to the difference in the formulation of the cream compared with the film formulation. Skin dosimetry verification and double blinding are essential for radiation skin care comparative studies.

    A new precision volume measurement system based on a Kansas City Plant (KCP) design was built to support the volume measurement needs of the Gas Transfer Systems (GTS) department at Sandia National Labs (SNL) in California. An engineering study was undertaken to verify or refute KCP's claims of 0.5% accuracy. The study assesses the accuracy and precision of the system. The system uses the ideal gas law and precise pressure measurements (of low-pressure helium) in a temperature and computer controlled environment to ratio a known volume to an unknown volume.

Os experimentos em batelada foram realizados em uma unidade piloto de micro e ultrafiltração que utiliza o princípio de filtração tangencial com membranas. Foram utilizadas membranas tubulares cerâmicas de α-Al2O3/TiO2 com diâmetros médios de poro de 0,2; 0,4 e 0,8 µm e área de filtração de 0,005 m2, na temperatura de 60ºC e pressões aplicadas através da membrana de 1,0; 2,0 e 3,0 bar. O desempenho das membranas foi avaliado pela capacidade de retenção de glicerina e pelos valores de fluxos permeados após estabilização. O baixo teor de glicerina obtido no permeado demonstra forte perspectiva da utilização de membranas cerâmicas na etapa de separação de biodiesel.This study investigated the efficiency of microfiltration with ceramic membranes in separating biodiesel and glycerin. Synthetic blends (feed solution were prepared with mass composition of 80% biodiesel, 10% glycerin and 10% anhydrous ethanol. Runs were performed in the micro and ultrafiltration module, in batch mode, using tangential filtration. Experiments were carried out with Al2O3/TiO2 tubular ceramic membranes with average pore size of 0.2, 0.4 and 0.8 µm, filtration area of 0.005 m2, at 60ºC and transmembrane pressures of 1.0, 2.0 and 3.0 bar. Membrane performance was evaluated based on its capacity to retain glycerin and permeate flux values. The low content of glycerin in the permeate, 0.04-0.1 wt%, demonstrates a high potential with respect to the use of ceramic membranes in the separation stage of biodiesel.

    2015-01-01

    It has been recently conjectured that scattering amplitudes in planar N=4 super Yang-Mills are given by the volume of the (dual) amplituhedron. In this paper we show some interesting connections between the tree-level amplituhedron and a special class of differential equations. In particular we demonstrate how the amplituhedron volume for NMHV amplitudes is determined by these differential equations. The new formulation allows for a straightforward geometric description, without any reference to triangulations. Finally we discuss possible implications for volumes related to generic N^kMHV amplitudes.

    Flow volumes are extended for use in unsteady (time-dependent) flows. The resulting unsteady flow volumes are the 3 dimensional analog of streamlines. There are few examples where methods other than particle tracing have been used to visualize time varying flows. Since particle paths can become convoluted in time there are additional considerations to be made when extending any visualization technique to unsteady flows. We will present some solutions to the problems which occur in subdivision, rendering, and system design. We will apply the unsteady flow volumes to a variety of field types including moving multi-zoned curvilinear grids.

    Full Text Available Surgical lung volume reduction can improve exercise performance and forced expiratory volume in one second in patients with emphysema. However, the procedure is associated with a 5% mortality rate and a nonresponse rate of 25%. Accordingly, interest has focused on alternative ways of reducing lung volume. Two principle approaches are used: collapse of the diseased area using blockers placed endobronchially and the creation of extrapulmonary pathways. Preliminary data from the former approach suggest that it can be successful and that the magnitude of success is related to reduction in dynamic hyperinflation.

    2015-10-01

    Using an athermal quasistatic simulation protocol, we study the distribution of free volumes in sheared hard-particle packings close to, but below, the random-close packing threshold. We show that under shear, and independent of volume fraction, the free volumes develop features similar to close-packed systems — particles self-organize in a manner as to mimick the isotropically jammed state. We compare athermally sheared packings with thermalized packings and show that thermalization leads to an erasure of these structural features. The temporal evolution in particular the opening-up and the closing of free-volume patches is associated with the single-particle dynamics, showing a crossover from ballistic to diffusive behavior.

    We develop a general regulated volume expansion for the volume of a manifold with boundary whose measure is suitably singular along a separating hypersurface. The expansion is shown to have a regulator independent anomaly term and a renormalized volume term given by the primitive of an associated anomaly operator. These results apply to a wide range of structures. We detail applications in the setting of measures derived from a conformally singular metric. In particular, we show that the anomaly generates invariant (Q-curvature, transgression)-type pairs for hypersurfaces with boundary. For the special case of anomalies coming from the volume enclosed by a minimal hypersurface ending on the boundary of a Poincare--Einstein structure, this result recovers Branson's Q-curvature and corresponding transgression. When the singular metric solves a boundary version of the constant scalar curvature Yamabe problem, the anomaly gives generalized Willmore energy functionals for hypersurfaces with boundary. Our approach ...

    Based on the speed of sound tester, the velocity of longitudinal waves which propagates in different concentrations of glycerol solution were measured by using transit time ultrasonic. With wave theory, the bulk modulus in different concentrations of glycerol solution were obtained indirectly. Meanwhile, the relationship between the bulk modulus and concentration of Glycerol solution was discussed and analyzed qualitatively and quantitatively. Finally, the bulk modulus of glycerin solution and its concentration were given by the experimental diagram and the fitting equation. The results show that when the concentration of glycerol increases, the bulk modulus increases. And there is a linear relationship between glycerol solution volumetric modulus and its concentration. This finding has important reference and application for further study of the mechanics of materials, chemical industry and mechanical properties of liquids and so on.%基于声速测试仪,利用时差法测量了超声波在不同浓度甘油溶液中传播纵波的速度,结合波动学理论间接求出了不同浓度下甘油溶液的体变模量.对甘油溶液的体变模量与其浓度的关系进行了定性和定量的研究与分析,给出了甘油溶液的体变模量与其浓度的关系图及线性拟合方程.研究结果表明,随着甘油溶液浓度的不断增加,甘油溶液的体变模量也随之增加,而且甘油溶液的体变模量与其浓度呈线性关系.这一研究结论在材料力学、化学工业以及进一步研究液体力学特性等方面有着重要的参考和应用价值.

  14. Reachable volume RRT

    KAUST Repository

    McMahon, Troy

    2015-05-01

    © 2015 IEEE. Reachable volumes are a new technique that allows one to efficiently restrict sampling to feasible/reachable regions of the planning space even for high degree of freedom and highly constrained problems. However, they have so far only been applied to graph-based sampling-based planners. In this paper we develop the methodology to apply reachable volumes to tree-based planners such as Rapidly-Exploring Random Trees (RRTs). In particular, we propose a reachable volume RRT called RVRRT that can solve high degree of freedom problems and problems with constraints. To do so, we develop a reachable volume stepping function, a reachable volume expand function, and a distance metric based on these operations. We also present a reachable volume local planner to ensure that local paths satisfy constraints for methods such as PRMs. We show experimentally that RVRRTs can solve constrained problems with as many as 64 degrees of freedom and unconstrained problems with as many as 134 degrees of freedom. RVRRTs can solve problems more efficiently than existing methods, requiring fewer nodes and collision detection calls. We also show that it is capable of solving difficult problems that existing methods cannot.

  19. Volumes of chain links

    Kaiser, James; Rollins, Clint

    2011-01-01

    Agol has conjectured that minimally twisted n-chain links are the smallest volume hyperbolic manifolds with n cusps, for n at most 10. In his thesis, Venzke mentions that these cannot be smallest volume for n at least 11, but does not provide a proof. In this paper, we give a proof of Venzke's statement. The proof for n at least 60 is completely rigorous. The proof for n between 11 and 59 uses a computer calculation, and can be made rigorous for manifolds of small enough complexity, using methods of Moser and Milley. Finally, we prove that the n-chain link with 2m or 2m+1 half-twists cannot be the minimal volume hyperbolic manifold with n cusps, provided n is at least 60 or |m| is at least 8, and we give computational data indicating this remains true for smaller n and |m|.

    2005-01-01

    Full Text Available The topological active volumes (TAVs model is a general model for 3D image segmentation. It is based on deformable models and integrates features of region-based and boundary-based segmentation techniques. Besides segmentation, it can also be used for surface reconstruction and topological analysis of the inside of detected objects. The TAV structure is flexible and allows topological changes in order to improve the adjustment to object's local characteristics, find several objects in the scene, and identify and delimit holes in detected structures. This paper describes the main features of the TAV model and shows its ability to segment volumes in an automated manner.

  4. Aperiodic Volume Optics

    Science.gov (United States)

    Gerke, Tim D.

    Presented in this thesis is an investigation into aperiodic volume optical devices. The three main topics of research and discussion are the aperiodic volume optical devices that we call computer-generated volume holograms (CGVH), defects within periodic 3D photonic crystals, and non-periodic, but ordered 3D quasicrystals. The first of these devices, CGVHs, are designed and investigated numerically and experimentally. We study the performance of multi-layered amplitude computer-generated volume holograms in terms of efficiency and angular/frequency selectivity. Simulation results show that such aperiodic devices can increase diffraction efficiency relative to periodic amplitude volume holograms while maintaining angular and wavelength selectivity. CGVHs are also designed as voxelated volumes using a new projection optimization algorithm. They are investigated using a volumetric diffraction simulation and a standard 3D beam propagation technique as well as experimentally. Both simulation and experiment verify that the structures function according to their design. These represent the first diffractive structures that have the capacity for generating arbitrary transmission and reflection wave fronts and that provide the ability for multiplexing arbitrary functionality given different illumination conditions. Also investigated and discussed in this thesis are 3D photonic crystals and quasicrystals. We demonstrate that these devices can be fabricated using a femtosecond laser direct writing system that is particularly appropriate for fabrication of such arbitrary 3D structures. We also show that these devices can provide 3D partial bandgaps which could become complete bandgaps if fabricated using high index materials or by coating lower index materials with high index metals. Our fabrication method is particularly suited to the fabrication of engineered defects within the periodic or quasi-periodic systems. We demonstrate the potential for fabricating defects within

    There exists, in general, no unique definition of the size (volume, area, etc., depending on dimension) of a soliton. Here we demonstrate that the geometric volume (area etc.) of a soliton is singled out in the sense that it exactly coincides with the thermodynamical or continuum-mechanical volume. In addition, this volume may be defined uniquely for rather arbitrary solitons in arbitrary dimensions.

Esses tecidos foram usados na restauração da jugular externa e se constituíram de artéria carótida comum homóloga (ACCHo, no grupo I, e veia jugular externa heteróloga (VJEHe, no grupo II. Para a restauração, utilizaram-se duas técnicas de anastomose da jugular, sendo, no grupo I, a técnica de bypass e, no grupo II, a substituição de um segmento da jugular esquerda por meio de anastomose vascular término-terminal. Para avaliar a trombogênese local e a histocompatibilidade, foram realizados exames clínicos, hematológicos, ecoDopplercardiográficos e histológicos dos segmentos vasculares enxertados. Os segmentos foram colhidos após 45 dias da avaliação pós-operatória, tendo a jugular direita como testemunha para os exames histológicos. Ambos os tecidos foram compatíveis quando implantados nos eqüinos, sem processo inflamatório acentuado, indicativo de rejeição. A técnica de bypass não foi eficiente na restauração da jugular, ocorrendo trombose obliterante dos enxertos de ACCHo.

    In the perioperative period, anesthesiologists and postanesthesia care unit (PACU) nurses routinely prepare and administer small-volume IV injections, yet the accuracy of delivered medication volumes in this setting has not been described. In this ex vivo study, we sought to characterize the degree to which small-volume injections (≤0.5 mL) deviated from the intended injection volumes among a group of pediatric anesthesiologists and pediatric postanesthesia care unit (PACU) nurses. We hypothesized that as the intended injection volumes decreased, the deviation from those intended injection volumes would increase. Ten attending pediatric anesthesiologists and 10 pediatric PACU nurses each performed a series of 10 injections into a simulated patient IV setup. Practitioners used separate 1-mL tuberculin syringes with removable 18-gauge needles (Becton-Dickinson & Company, Franklin Lakes, NJ) to aspirate 5 different volumes (0.025, 0.05, 0.1, 0.25, and 0.5 mL) of 0.25 mM Lucifer Yellow (LY) fluorescent dye constituted in saline (Sigma Aldrich, St. Louis, MO) from a rubber-stoppered vial. Each participant then injected the specified volume of LY fluorescent dye via a 3-way stopcock into IV tubing with free-flowing 0.9% sodium chloride (10 mL/min). The injected volume of LY fluorescent dye and 0.9% sodium chloride then drained into a collection vial for laboratory analysis. Microplate fluorescence wavelength detection (Infinite M1000; Tecan, Mannedorf, Switzerland) was used to measure the fluorescence of the collected fluid. Administered injection volumes were calculated based on the fluorescence of the collected fluid using a calibration curve of known LY volumes and associated fluorescence.To determine whether deviation of the administered volumes from the intended injection volumes increased at lower injection volumes, we compared the proportional injection volume error (loge [administered volume/intended volume]) for each of the 5 injection volumes using a linear

    Natural fatty alcohols have become the important base feedstock of fine chemical industry. The lifetime of the commercial Cu/Zn catalyst was shortened· due to its deaetivation. Deactivation of Cu/Zn catalyst caused by glycerine and glyceryl triaeetate in hydrogenation of methyl lanrate to lanryl alcohol was studied. The catalysts were characterized by XRD, BET, TG-DTA, and the product was analyzed by GC-MS. The results indicated that glycerine and glyeeryl triacetate, in the presence of Cu/Zn catalyst,could be decomposed to oleophobic 1,2-propanediol and insoluble cross-linked solids, respoetively, which caused surface area decrement and deactivation of the catalyst by adsorption and then active site occlusion.%脂肪醇是精细化工的重要原料,工业Cu/Zn催化剂易失活,使用寿命较短.在间歇釜高压反应器中考察了甘油和三乙酸甘油酯对Cu/Zn催化剂上月桂酸甲酯加氢制月桂醇催化活性的影响,采用XRD、BET、GC-MS和TG-DTA等分析和表征方法对失活催化剂和反应产物进行了分析.结果表明,甘油和三乙酸甘油酯在催化剂作用下分别得到强疏油性的1,2-丙二醇和难溶的交联物,并吸附在催化剂上,导致催化剂活性中心被覆盖,催化剂比表面积减小,引起催化剂失活.

    Full Text Available We were able to determine the volume of an industrial autoclave sterilization tank using a technique learned in calculus. By measuring the dimensions of the tank and roughly estimating the equation of curvature at the ends of the tank, we were able to revolve half of the end of the tank around the x axis to get its fluid volume. Adding the two volumes of the ends and the volume of the cylindrical portion on the tank yielded the total volume.

  4. Cosmological Measures without Volume Weighting

    CERN Document Server

    Page, Don N

    2008-01-01

    Many cosmologists (myself included) have advocated volume weighting for the cosmological measure problem, weighting spatial hypersurfaces by their volume. However, this often leads to the Boltzmann brain problem, that almost all observations would be by momentary Boltzmann brains that arise very briefly as quantum fluctuations in the late universe when it has expanded to a huge size, so that our observations (too ordered for Boltzmann brains) would be highly atypical and unlikely. Here it is suggested that volume weighting may be a mistake. Volume averaging is advocated as an alternative. One consequence would be a loss of the argument for eternal inflation.

  6. Volume and Surface-Enhanced Volume Negative Ion Sources

    CERN Document Server

    Stockli, M P

    2013-01-01

    H- volume sources and, especially, caesiated H- volume sources are important ion sources for generating high-intensity proton beams, which then in turn generate large quantities of other particles. This chapter discusses the physics and technology of the volume production and the caesium-enhanced (surface) production of H- ions. Starting with Bacal's discovery of the H- volume production, the chapter briefly recounts the development of some H- sources, which capitalized on this process to significantly increase the production of H- beams. Another significant increase was achieved in the 1990s by adding caesiated surfaces to supplement the volume-produced ions with surface-produced ions, as illustrated with other H- sources. Finally, the focus turns to some of the experience gained when such a source was successfully ramped up in H- output and in duty factor to support the generation of 1 MW proton beams for the Spallation Neutron Source.

    Full Text Available Com o objetivo de testar o implante de cartilagem auricular heteróloga conservada em glicerina a 98% como alternativa para reparar defeitos na parede torácica em felinos, foram estudados doze animais adultos, sendo distribuídos em dois grupos GI e GII, e avaliados após 60 dias de pós-operatório. Todos os animais foram submetidos à ressecção costal na porção média do tórax abrangendo a 7ª, 8ª e 9ª costelas e posterior implante de cartilagem conchal heteróloga conservada em glicerina a 98%. No GI, foi preservada a musculatura adjacente, já no GII, a musculatura foi retirada. Os animais foram avaliados clinicamente no pós-operatório e, ao final do período, submetidos à eutanásia e necropsia para avaliação macroscópica e microscópica da região do implante. Observou-se proliferação de tecido fibrovascular neovascularizado sobre o implante, com aderência pulmonar e diafragmática em algumas das unidades experimentais. O implante de cartilagem heteróloga conservado em glicerina a 98% pode ser utilizado para reconstrução de parede costal cujo defeito abranja o espaço de parte de três costelas. O implante em 60 dias é substituído por tecido cicatricial, sem apresentar sinais clínicos de rejeição.Twelve adult cats were divided in groups GI and GII with the objective of testing a dog auricular cartilage implant conserved in 98% glycerin as an alternative to repair thoracic wall defects.

  13. Discretized Volumes in Numerical Methods

    CERN Document Server

    Antal, Miklós

    2007-01-01

    We present two techniques novel in numerical methods. The first technique compiles the domain of the numerical methods as a discretized volume. Congruent elements are glued together to compile the domain over which the solution of a boundary value problem is sought. We associate a group and a graph to that volume. When the group is symmetry of the boundary value problem under investigation, one can specify the structure of the solution, and find out if there are equispectral volumes of a given type. The second technique uses a complex mapping to transplant the solution from volume to volume and a correction function. Equation for the correction function is given. A simple example demonstrates the feasibility of the suggested method.

    2004-01-01

    The need of taking into account the change of compartment volume when developing chemical kinetics analysis inside the living cell is discussed. Literature models of a single enzymatic Michaelis-Menten process, glycolytic oscillations, and mitotic cyclin oscillations were tested with appropriate theoretical extension in the direction of volume modification allowance. Linear and exponential type of volume increase regimes were compared. Due to the above, in a growing cell damping of the amplitude, phase shift, and time pattern deformation of the metabolic rhythms considered were detected, depending on the volume change character. The performed computer simulations allow us to conclude that evolution of the cell volume can be an essential factor of the chemical kinetics in a growing cell. The phenomenon of additional metabolite oscillations caused by the periodic cell growth and division was theoretically predicted and mathematically described. Also, the hypothesis of the periodized state in the growing cell as the generalization of the steady-state was formulated.

    As the development of computer graphics, scientific visualization and advanced imaging scanner and sensor technology, high quality animation making of volume data set has been a challenging in industries. A simple animation framework by using current volume visualization techniques is proposed in this paper. The framework consists of two pipelines: one is surface based method by using marching cubes algorithm, the other is volume rendering method by using shear-warp method. The volume visualization results can not only be used as key frame sources in the animation making, but also can be directly used as animation when the volume visualization is in stereoscopic mode. The proposed framework can be applied into fields such as medical education, film-making and archaeology.

  16. Sparse PDF Volumes for Consistent Multi-Resolution Volume Rendering

    KAUST Repository

    Sicat, Ronell Barrera

    2014-12-31

    This paper presents a new multi-resolution volume representation called sparse pdf volumes, which enables consistent multi-resolution volume rendering based on probability density functions (pdfs) of voxel neighborhoods. These pdfs are defined in the 4D domain jointly comprising the 3D volume and its 1D intensity range. Crucially, the computation of sparse pdf volumes exploits data coherence in 4D, resulting in a sparse representation with surprisingly low storage requirements. At run time, we dynamically apply transfer functions to the pdfs using simple and fast convolutions. Whereas standard low-pass filtering and down-sampling incur visible differences between resolution levels, the use of pdfs facilitates consistent results independent of the resolution level used. We describe the efficient out-of-core computation of large-scale sparse pdf volumes, using a novel iterative simplification procedure of a mixture of 4D Gaussians. Finally, our data structure is optimized to facilitate interactive multi-resolution volume rendering on GPUs.

    We consider a sphere of 7.5 Mpc radius, which contains 355 galaxies with accurately measured distances, to detect the nearest empty volumes. Using a simple void detection algorithm, we found six large (mini)voids in Aquila, Eridanus, Leo, Vela, Cepheus and Octans, each of more than 30 Mpc^3. Besides them, 24 middle-size "bubbles" of more than 5 Mpc^3 volume are detected, as well as 52 small "pores". The six largest minivoids occupy 58% of the considered volume. Addition of the bubbles and pores to them increases the total empty volume up to 75% and 81%, respectively. The detected local voids look like oblong potatoes with typical axial ratios b/a = 0.75 and c/a = 0.62 (in the triaxial ellipsoide approximation). Being arranged by the size of their volume, local voids follow power law of volumes-rankes dependence. A correlation Gamma-function of the Local Volume galaxies follows a power low with a formally calculated fractal dimension D = 1.5. We found that galaxies surrounding the local minivoids do not differ...

    Full Text Available Analysis of raw volume data generated from different scanning technologies faces a variety of challenges, related to search, pattern recognition, spatial understanding, quantitative estimation, and shape description. In a previous study, we found that the Volume Cracker (VC 3D interaction (3DI technique mitigated some of these problems, but this result was from a tethered glove-based system with users analyzing simulated data. Here, we redesigned the VC by using untethered bare-hand interaction with real volume datasets, with a broader aim of adoption of this technique in research labs. We developed symmetric and asymmetric interfaces for the Bare-Hand Volume Cracker (BHVC through design iterations with a biomechanics scientist. We evaluated our asymmetric BHVC technique against standard 2D and widely used 3D interaction techniques with experts analyzing scanned beetle datasets. We found that our BHVC design significantly outperformed the other two techniques. This study contributes a practical 3DI design for scientists, documents lessons learned while redesigning for bare-hand trackers, and provides evidence suggesting that 3D interaction could improve volume data analysis for a variety of visual analysis tasks. Our contribution is in the realm of 3D user interfaces tightly integrated with visualization, for improving the effectiveness of visual analysis of volume datasets. Based on our experience, we also provide some insights into hardware-agnostic principles for design of effective interaction techniques.

    This article presents a solution to volume measurement object packing using 3D cameras (such as the Microsoft KinectTM). We target application scenarios, such as warehouses or distribution and logistics companies, where it is important to promptly compute package volumes, yet high accuracy is not pivotal. Our application auto- matically detects cuboid objects using the depth camera data and computes their volume and sorting it allowing space optimization. The proposed methodology applies to a point cloud simple computer vision and image processing methods, as connected components, morphological operations and Harris corner detector, producing encouraging results, namely an accuracy in volume measurement of 8mm. Aspects that can be further improved are identified; nevertheless, the current solution is already promising turning out to be cost effective for the envisaged scenarios.

    Knowledge of in vivo thyroid volume has both diagnostic and therapeutic importance and could lead to a more precise quantification of absolute activity contained in the thyroid gland. In order to improve single-photon emission computed tomography (SPECT) quantitation, attenuation correction was performed according to Chang's algorithm. The dual-window method was used for scatter subtraction. We used a Monte Carlo simulation of the SPECT system to accurately determine the scatter multiplier factor k. Volume estimation using SPECT was performed by summing up the volume elements (voxels) lying within the contour of the object, determined by a fixed threshold and the gray level histogram (GLH) method. Thyroid phantom and patient studies were performed and the influence of 1) fixed thresholding, 2) automatic thresholding, 3) attenuation, 4) scatter, and 5) reconstruction filter were investigated. This study shows that accurate volume estimation of the thyroid gland is feasible when accurate corrections are perform...

    Black holes that have nearly evaporated are often thought of as small objects, due to their tiny exterior area. However, the horizon bounds large spacelike hypersurfaces. A compelling geometric perspective on the evolution of the interior geometry was recently shown to be provided by a generally covariant definition of the volume inside a black hole using maximal surfaces. In this article, we expand on previous results and show that finding the maximal surfaces in an arbitrary spherically symmetric spacetime is equivalent to a 1 +1 geodesic problem. We then study the effect of Hawking radiation on the volume by computing the volume of maximal surfaces inside the apparent horizon of an evaporating black hole as a function of time at infinity: while the area is shrinking, the volume of these surfaces grows monotonically with advanced time, up to when the horizon has reached Planckian dimensions. The physical relevance of these results for the information paradox and the remnant scenarios are discussed.

    A method is disclosed for determining the volume of compressible gas in a system including incompressible substances in a zero-gravity environment consisting of measuring the change in pressure (delta P) for a known volume change rate (delta V/delta t) in the polytrophic region between isothermal and adiabatic conditions. The measurements are utilized in an idealized formula for determining the change in isothermal pressure (delta P sub iso) for the gas. From the isothermal pressure change (delta iso) the gas volume is obtained. The method is also applicable to determi
