In our experiments production performances of Siberian sterlet were tested under intensive tank conditions. During the 25 days long experiment effectiveness of weaning to artificial diet of the fish was investigated. Production performances of fish fed on exclusively dry diet from the beginnings were lower than the other two groups. Between the values of sterlets fed on live food also then suddenly vs. continuously were weaned to dry diet there were no significant differences. Based on our results live food feeding could be suggested for the Siberian sterlet larvae for some days but the method of the weaning to dry diet has no significant influence to the production performances. In 21 days long experiment four different feeding frequencies were tested in Siberian sterlet (~13 g) fingerlings. Dry feed was offered for the fish continuously, 2, 3 and 4 times per day. There were no significant differences between the values of the four treatments. Based on our results there is no high influence of feeding frequency in case of this size group of Siberian sterlet. During the nursing in two different size groups of Siberian sterlet the optimal daily amounts of feed were aimed to determine. In case of growth values of the group fed at 7% of the total biomass were higher than the other two groups (3 and 5%). Feeding performances of fish fed at 5% were significantly better than fish fed at 7%. Based on our results for ~20 g size of the subspecies at least 5% of total body weight could be suggested. In case of ~150 g size of the fish the production performances of fish fed at 1% were lower than the other two groups (2 and 3%). Between the values of stocks fed at 2 and 3% there were no significant differences. Based on these results 2% of total body weight of dry feed could be suggested for the Siberian sterlet with ~150 g body weight.

Induced Changes

Anesthetized cats were supported on electronic scales placed under the head, thorax, abdomen and hindquarters, and the changes in the weights supported by these scales were recorded while blood was withdrawn and while blood and saline were infused. The recorded changes in weight indicated that the abdomen and the thorax both contributed significantly to the volume of withdrawn blood and that infused fluids were taken up by both regions. The blood volume of neither region was conserved at the expense of the other. The average weight change of the hindquarters was 5–10% of the over-all response, but in many cases the weight of the hindquarters was stable during an experiment. The average error in measurement of changes in total body weight was 6%. Interactions between the scales were evaluated by injecting mercury into pouches placed at specific anatomic locations. Interactions did occur, but were not so great as to invalidate the method. Submitted on September 16, 1960

Simplistic Model

Objective: To determine by examining the physical characteristics of pairs of people who cohabitate whether each is physically capable of performing two-inch chest compression on the other. Methods: Name, gender, age, total body weight, and hands on scale weight (“HOSW”) data was collected from couples. HOSW is the reading on a scale when one is kneeling in front of the scale and pressing down with the hands as if performing CPR, until the knees barely leave the ground. One member of the cohort mechanically measured his chest stiffness. Chest stiffness for the cohort was calculated from a simplistic model where the measured subject’s relationship between chest stiffness and total body weight was assumed to prevail in all other test subjects. Doing so yielded an average chest stiffness of 128 pounds, as compared to the actual average adult chest stiffness of 130 pounds. A similar method was used with the heel of the foot. The result was FOSW, the force one could apply to a chest while performing Pedal Compression. A subject with an HOSW or FOSW equal to or greater than their partner’s chest stiffness was judged to be capable of performing guideline-compliant chest compression on the other using manual or pedal compression, respectively. The two outcome measures for each couple were: each’s physical ability to perform two-inch compression on the other, using manual and pedal compression. Results: At the time this abstract was submitted, data from twelve couples showed that slightly more than half the male subjects had sufficient HOSW to perform two-inch manual compression on their wife, and no wives had sufficient HOSW TO PERFORM a two-inch compression on their husband. In the 700 cardiac arrests in a private residence each day, two-thirds of the victims are male and will not receive two-inch compression. The results show the number of females and males that can apply enough force to their spouse’s chest to perform a two-inch compression with manual chest compression and pedal (heel) compression with FOSW at 95 and 90 percent of body weight. Zero of twelve females weighed enough to perform and seven of twelve males weighed enough to perform a two inch compression on their spouse using manual compression. One of twelve females and ten of twelve males weighed enough to perform a two inch compression on their spouse using pedal compression under the 95% of body weight equals FOSW model. Zero of twelve females and ten of twelve males weighed enough to perform a two inch compression on their spouse using pedal compression under the 90% of body weight equals FOSW model. Heel compression increases the likelihood of a male’s being able to perform a two inch compression significantly. Heel compression only improves a female’s likelihood of performing a two-inch compression using the 95% of body weight assumption.

Hypoxia Treatment

A growth trial was conducted to detect the effects of different diets on the growth performance and hypoxia adaptation capacity of Mississippi Paddlefish (Polyodon spathula) larvae. The larvae were fed with live food, formulated diets, and 1/2 live food with 1/2 formulated diets. After a 15-d growth trial, final body weight and total body length were measured, and five larvae from each dietary group were subjected to 1 h of hypoxia treatment. Serum total antioxidant capacity (T-AOC), serum superoxide dismutase (SOD), and liver malondialdehyde (MDA) were measured. Final body weight and weight gain of the fish fed live food were significantly higher than the values for the other two groups. Total body length of the fish fed live food and 1/2 live food with 1/2 formulated diets exhibited no significant difference. After hypoxia treatment, serum T-AOC and SOD activities of the fish fed formulated diets were significantly lower than those of the other two groups. Liver MDA content of the fish fed with live food was significantly higher than that of the other two groups. In conclusion, larval paddlefish fed with an appropriate proportion of live food and formulated diets exhibit improved adaptive capacity to hypoxia.

Abstract Objectives Iodinated contrast media (ICM) could be more appropriately dosed on patient lean body weight (LBW) than on total body weight (TBW). Methods After Ethics Committee approval, trial registration NCT03384979, patients aged ≥ 18 years scheduled for multiphasic abdominal CT were randomised for ICM dose to LBW group (0.63 gI/kg of LBW) or TBW group (0.44 gI/kg of TBW). Abdominal 64-row CT was performed using 120 kVp, 100–200 mAs, rotation time 0.5 s, pitch 1, Iopamidol (370 mgI/mL), and flow rate 3 mL/s. Levene, Mann–Whitney U, and χ2 tests were used. The primary endpoint was liver contrast enhancement (LCE). Results Of 335 enrolled patients, 17 were screening failures; 44 dropped out after randomisation; 274 patients were analysed (133 LBW group, 141 TBW group). The median age of LBW group (66 years) was slightly lower than that of TBW group (70 years). Although the median ICM-injected volume was comparable between groups, its variability was larger in the former (interquartile range 27 mL versus 21 mL, p = 0.01). The same was for unenhanced liver density (IQR 10 versus 7 HU) (p = 0.02). Median LCE was 40 (35–46) HU in the LBW group and 40 (35–44) HU in the TBW group, without significant difference for median (p = 0.41) and variability (p = 0.23). Suboptimal LCE (< 40 HU) was found in 64/133 (48%) patients in the LBW group and 69/141 (49%) in the TBW group, but no examination needed repeating. Conclusions The calculation of the ICM volume to be administered for abdominal CT based on the LBW does not imply a more consistent LCE.

Rate Of Accumulation

Pregnant rats were subjected to either a folic-acid-deficient regimen that produces multiple congenital skeletal malformations, or a control folic-acid-supplemented regimen. Fetal limbs were extirpated on days 16 and 18 of gestation, pooled from each litter, homogenized, and aliquots set aside for hydroxyproline, protein and DNA determinations. We found that (1) the amount of protein recovered per treated limb was approximately half that of controls on both days, (2) the amount of protein recovered per treated or controlday-18 limb was twice that of a day-16 limb, (3) treated limbs constituted the same percentage of total body weight as in controls on day 16, but a smaller percentage than in controls on day 18, and (4) the concentration of hydroxyproline (μg/mg protein) was significantly less for treated limbs than for controls on day 18 of gestation. We noted also that: (1) lowest hydroxyproline concentrations were found in limbs from treated fetuses with gross limb malformations, (2) intermediate concentrations were found in limbs of treated fetuses not exhibiting gross limb malformations, and (3) highest concentrations were found in control limbs. We suggest that the treatment resulted in (1) a decreased rate of accumulation of protein in limbs prior to day 16, but not from day 16 to day 18, (2) a decreased rate of accumulation of some non-protein component(s) in treated limbs from day 16 to day 18, and (3) an altered collagen metabolism.

Total body weight of 9749 reindeer calves and 4798 adult reindeer were measured from 1984 to 1999 on the Seward Peninsula, western Alaska, USA. Growth rates of male and female calves, and annual growth patterns of adults were determined. Male calves grew faster than female calves. Reproductive females were lighter than non-reproductive females during summer but there was no effect of reproduction on average body weights the following winter. Adult males age 3-5 were heavier during summer than winter. Castrated males weighed the same as uncastrated males in summer, but were significantly heavier in winter, and did not display the large annual fluctuations in weight typical of reproductive males and females. Growth rates were higher and body weights greater in this herd than many other cir-cumpolar reindeer populations. We suggest these kinds of physiological indices should be used to monitor the possible effects of spatial and temporal variation in population density and to evaluate changes in herding practices.

Total Body Weight Loss

Abstract Over 2.5 billion people worldwide are overweight or obese. Multidisciplinary weight management interventions have evolved to address the complexity of weight loss for those with one or more chronic diseases, and the trend of weight regain. The aim of these interventions is to encourage sustainable lifestyle changes, resulting in weight loss and weight maintenance and improvements in comorbidities. While some prospective clinical trials have demonstrated efficacy, results are often not reported by real life practices. The aim of this study was to evaluate the effectiveness of a Sydney based multidisciplinary weight management clinic with endocrinology, dietetics, exercise physiology, psychology, and bariatric surgical domains. All patients who attended the clinic for weight loss purposes between March 2017 and April 2019 were included (n=220). A retrospective chart review was conducted. Patient data on weight, BMI, waist circumference, body composition measurements, and selected blood test results and co-morbidities were analysed. All patient therapy included endocrinological input for co-morbidity identification and management, lifestyle intervention (dietetic and exercise physiology input) with optional adjunct pharmacotherapy or psychological counselling. Of the 220 cohort, 20 of the patients had sleeve gastrectomy. Patient retention in the clinic after the first consultation was 85% (n=186), a high rate within the weight management community. 59% of patients achieved a minimum of 5% total body weight loss, including 18% who achieved greater than 10% total body weight loss. Additionally, 31% of patients lost enough weight to decrease their BMI class by up to 2 or more classes. Of the gastric sleeve cohort average excess body weight loss was 32kg (21-56kg) enhanced by multidisciplinary care in the lead up to surgery. Across the cohort some patients completely reversed co-morbidities; including dyslipidaemia (n=1), hypertension (n=3), NAFLD (n=1), pre-diabetes (n=8) and type 2 diabetes (n=3), OSA (n=1). These results demonstrate that obesity is a chronic condition that can be successfully managed. We have demonstrated significant durable weight loss and improvement in metabolic co-morbidities with holistic coordinated care. Future directions include translating this model of care into standard practice in Australia and other countries where obesity to date not received the same coordinated approach as other chronic conditions.

1. Water content varies from 64 to 73% of the total body weight and 72-76% of the fatless body weight of 24 hr. old unflown alatae of Aphis fabae. 2. Water loss during flight may be attributed to evaporation and excretion. A mean of 0.07 mg. water is lost per aphid during a 6 hr. tethered fligh a 25-26° C. and 57-82% R.H., corresponding to c. 9% body weight; at least 66% of the loss (c. 1% body weight/hr.) is by evaporation. 3. Excretion during fligh is not affected by relative humidity differences over the range 41-75% at 25%26° C., but the relative amounts of water lost during prolonged flight are inversely related to relative humidity, because of the effect of humidity on evaporation. 4. Proportion of water in he body does no change significantly during tethered fligh. Mean percentage water to total body weight increases from c. 68-69% during 6 hr.; mean percentage water to fatless body weight decreases from c. 74 to 73%. 5. Water loss is evidently not a limiting factor to fligh in atmospheres of saturation deficit less than c. 23 mm. Hg.

Studies on vancomycin pharmacokinetics in acute kidney injury (AKI) patients on high-volume peritoneal dialysis (HVPD) are lacking. We studied the pharmacokinetics of intravenous (IV) vancomycin in AKI patients treated by HVPD who received a prescribed single IV dose of vancomycin (15 - 20 mg/kg total body weight) to determine the extent of vancomycin removal and to establish vancomycin dosing guidelines for the empirical treatment of AKI patients receiving HVPD. The application of 18 mg/kg vancomycin every 48 - 72 hours in AKI patients undergoing HVPD was required to maintain therapeutic concentrations.
