An attempt was made to advance the spawning period of Labeo dyocheilus (McClelland, 1839) by pretreatment with the synthetic gonadotropin releasing hormone analogue, Ovatide. Total 12 females and 24 males (1: 2 ratio) were used for breeding operations conducted during 30th May to 30th June 2016 comprising six sets. Female fishes of set I to IV were pretreated with intramuscular injection of the ovatide at the rate 0.3 ml kg-1 body weight twice at an interval of two weeks while males were injected @ 0.1 ml kg-1 body weight once before 15 days of induced breeding trial for achieving advance maturity and spawning during pre-spawning phase. Fishes of set V and VI were not subjected to any pretreatment with ovatide. On 30th of June all the six breeding sets were were treated with ovatide for induced spawning. Female and males were injected at 0.7 ml kg-1 and 0.3 ml kg-1 of body weight, respectively and left overnight in FRP tanks for spawning. Results indicated that in sets I to IV, fishes successfully spawned and fertilised eggs were collected in morning hours whereas fishes of set V and VI failed to spawn. Fertilisation and survival rates recorded were 79-82% and 67-71%, respectively. Results indicated that treatment of ovatide during prespawning phase is beneficial for advancing the gonadal maturity, successful induced spawning and prolonging the breeding period which may play a key role in production of substantial quantity of seed of L. dyocheilus.

An experiment to evaluate the effectiveness immunostimulant and bacterin on humpback grouper have been conducted at the Disease Laboratory of Research Institute for Mariculture, Gondol, Bali. The experiment was designed in completely randomized design with four treatments in duplicates. Two hundred of humpback grouper juveniles (15-18 cm of total length, 55-65 g of body weight) were injected intraperitoneally with (A) bacterine at 107 cfu/kg body weight (BW), (B) peptidoglycan at 100 mg/kg BW, and (C) immuno star at 100 ml/kg BW, (D) control. The fish were then challenged with VNN by intramuscular injection at 10 days post treatment. Results showed that survival rates of juvenile after challenged with VNN were 60.00% (B & C), 53.34% (A), and 1.67% (control). Parameters of non-spesific immune respons showed that phagocytic activities were 17.56% (B), 17.55% (C), 13.11% (A), and 9.33% (control). In addition, lisozyme activities were 1.64 cm (B), 1.58 cm (C), 1.55 cm (A), and 1.46 cm (control). Immunostimulant and bacterin stimulated non-specific immune response, and increased survival rate of humpback grouper juvenile.

Abstract Objectives To determine appetite-regulating hormone levels in girls with central precocious puberty (CPP) before and after 20 weeks of gonadotropin-releasing hormone analogue (GnRH-A) treatment. Methods Eighteen newly diagnosed CPP girls were enrolled. Body composition measured by bioelectrical impedance analysis and GnRH-A test were performed with fasting serum leptin, ghrelin and peptide YY (PYY) measurements at baseline (before) and after 20 weeks of GnRH-A treatment. Results Following GnRH-A treatment, all patients had prepubertal gonadotropin and estradiol levels. Mean (SD) fat mass index (FMI) was significantly increased from 4.5 (1.7) to 5.0 (1.8) kg/m2 after treatment. Also, median (IQR) serum leptin level was significantly increased from 6.9 (4.2–8.6) to 7.4 (5.3–13.1) ng/mL. FMI had a positive correlation with serum leptin level (r=0.64, p=0.004). In contrast, no significant changes of serum ghrelin and PYY levels were observed. Conclusions Decreased estrogen following short-term GnRH-A treatment in CPP girls may cause an increase in appetite and consequently an elevation of FMI. Increased serum leptin may be a result of having increased FMI secondary to an increase in appetite.

The Impact

It has been acknowledged that excess body weight increases the risk of colorectal cancer (CRC); however, there is little evidence on the impact of body mass index (BMI) on CRC patients’ long-term oncologic results in Asian populations. We studied the influence of BMI on overall survival (OS), disease-free survival (DFS), and CRC-specific survival rates in CRC patients from the administrative claims datasets of Taiwan using the Kaplan–Meier survival curves and the log-rank test to estimate the statistical differences among BMI groups. Underweight patients (<18.50 kg/m2) presented higher mortality (56.40%) and recurrence (5.34%) rates. Besides this, they had worse OS (aHR:1.61; 95% CI: 1.53–1.70; p-value: < 0.0001) and CRC-specific survival (aHR:1.52; 95% CI: 1.43–1.62; p-value: < 0.0001) rates compared with those of normal weight patients (18.50–24.99 kg/m2). On the contrary, CRC patients belonging to the overweight (25.00–29.99 kg/m2), class I obesity (30.00–34.99 kg/m2), and class II obesity (≥35.00 kg/m2) categories had better OS, DFS, and CRC-specific survival rates in the analysis than the patients in the normal weight category. Overweight patients consistently had the lowest mortality rate after a CRC diagnosis. The associations with being underweight may reflect a reverse causation. CRC patients should maintain a long-term healthy body weight.

Before And After

Abstract Female hair sheep, 27 Dorper (DOR), 41 Katahdin (KAT), and 39 St. Croix (STC), were used to determine influences of nutritional planes before and after breeding on performance. There were 35 multiparous and 72 primiparous sheep, the latter 2.8±0.20 yr of age. Wheat straw [4% crude protein; dry matter (DM) basis] was consumed ad libitum and supplemented with approximately 0.25% initial body weight (BW) of soybean meal (SBM; Low) or a 1:3 mixture of SBM and rolled corn at 1% BW (High; DM). The supplementation period was 162 d, and with breeding of animals in 2 groups sequentially the pre-breeding period was 84 and 97 d and that after breeding began was 78 and 65 d. Wheat straw DM intake (1.75, 1.30, 1.57, 1.15, 1.80, and 1.38% BW; SEM=0.112), average daily gain (-46, 42, -44, 70, -47, and 51 g; SEM=7.3), and change in body condition score (-0.61, 0.36, -0.53, 0.27, -0.39, and -0.18 for DOR-Low, DOR-High, KAT-Low, KAT-High, STC-Low, and STC-High, respectively; SEM=0.058) were influenced (P &lt; 0.05) by supplement treatment. Birth rate (66.7, 93.5, 84.6, 95.5, 82.8, and 100.0; SEM=9.83) and individual lamb birth weight (4.50, 4.61, 4.28, 3.98, 3.73, and 3.88 kg; SEM=0.201) were not affected by supplement treatment (P = 0.063 and 0.787, respectively), although litter size (0.92, 1.21, 1.17, 1.86, 1.12, and 1.82; SEM=0.221) and total litter birth weight (5.84, 5.74, 5.92, 7.52, 5.04, and 6.78 kg for DOR-Low, DOR-High, KAT-Low, KAT-High, STC-Low, and STC-High, respectively; SEM=0.529) were greater (P &lt; 0.05) for High than for Low. In conclusion, although there was some compensation in wheat straw intake for the different levels of supplementation, SBM given alone rather than with cereal grain adversely affected body weight and condition and reproductive performance, the latter primarily through litter size but also via a trend for an effect on birth rate.

Abstract Background and Aims The prevalence of obesity has increased over the past decade in patients with End Stage Kidney Disease (ESKD). Obesity at the initiation of peritoneal dialysis (PD) was reported to adversely affect clinical outcomes. However, there are few studies on the prognostic relevance of weight gain after PD. Method We reviewed the change in body weight of 954 consecutive PD patients from the initiation of dialysis to 2 years after they remained on PD. Clinical outcomes including patient survival, technique survival, and peritonitis rate in the subsequent two years were reviewed. Results The mean age was 60.3 ± 12.2 years; 535 patients (56.1%) were men and 504 (52.8%) had diabetes. After the first 2 years on PD, the average change in body weight was 1.2± 5.1 kg; their body weight was 63.0 ± 13.3 kg; body mass index (BMI) 24.4 ± 4.4 kg/m2. The patient survival rates in the subsequent two years were 64.9%, 75.0%, and 78.9% (log rank test, p = 0.008) for patients with weight loss ≥3 kg during the first 2 years of PD weight change between -3 and +3 kg, and weight gain ≥3 kg, respectively. The corresponding technique survival rates in the subsequent two years were 93.1%, 90.1%, 91.3%, respectively (p = 0.110), and the peritonitis rates were 0.7±1.5, 0.6±1.7, and 0.6±1.1 episodes per patient-year, respectively (p = 0.3). When the actual BMI after the first 2 years of PD was categorized into underweight, normal weight, marginal overweight, overweight, and obesity groups, the patient survival rates in the subsequent two years were 77.3%, 75.2%, 73.3%, 74.3%, and 75.9%, respectively (p= 0.005), and technique survival 98.0%, 91.9%, 88.0%, 92.8%, and 81.0%, respectively (p= 0.001). After adjusting for confounding clinical factors by multivariate Cox regression models, weight gain ≥ 3kg during the first 2 years of PD was an independent protective factor for technique failure (adjusted hazard ratio [AHR] 0.049; 95% confidence interval [CI] 0.004-0.554, p = 0.015), but was an adverse predictor of patient survival (AHR 2.338, 95%CI 1.149-4.757, p = 0.019). In contrast, weight loss ≥ 3kg during the first 2 years of PD did not predict subsequent patient or technique survival. Conclusion Weight gain during the first 2 years of PD confers a significant risk of subsequent mortality but appears to be associated with a lower risk of technique failure. The mechanism of this discordant risk prediction deserves further study.
