Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC’s 7.97 ×103mm-3, RBC’s 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

The study was carried out at the Niger Delta University, Faculty of Agriculture Teaching and Research Farm, Bayelsa State. A total of Ninety six (96) growing snails (Archachatina marginata). Using Plantain peel as an additive, four diets were formulated at the levels of 0%, 3%, 6%, and 9% to form the treatment diets. The experiment lasted for eight (8) weeks during which the weight gain, feed intake, shell width, shell length, shell thickness and hematological parameters were obtained. The weight gain, shell width, shell length and shell thickness are not significantly different (p<0.05) whereas, the feed intake differed significantly (p<0.05) for all the treatment diets in the experiment. From the results, it was concluded that concentrate with 0% inclusion of Plantain peel meal was suitable for snail diets as it gave the best performance. The hematological parameters measured in the African giant land snails are White blood cell, Neutrophile and Lymphocyte differed significantly (p<0.05). Plantain peel can serve as source of potassium for other animals, as the highest percentage of potassium was found in the hemolymph of snails fed with 9% inclusion of plantain peel. It is recommended that; there should be no inclusion of plantain peels in the diet of the African giant land snails in order to achieve higher weight gain and feed intake.

Sinusoidal obstruction syndrome (SOS) is a rare complication after allogeneic hematopoietic stem cell transplantation (alloHSCT) caused by endothelial dysfunction. Previous definitions and diagnostic criteria for the presence of SOS include bilirubinemia, hepatomegaly and weight gain, but histological evaluation is still the only way to prove the diagnosis of SOS. However, biopsy remains an invasive technique and is therefore undesirable in the alloHSCT scenario. Hence, a non-invasive diagnostic strategy is critical. Besides thorough clinical assessment and laboratory values, ultrasound examination remains part of the diagnostic workflow in clinical routine. Previous studies defined sonographic abnormalities, which are associated with the occurrence of SOS, but a standardized protocol to perform reliable abdominal ultrasound has not been finally defined. In this study, we evaluated a multi-parameter protocol including laboratory values as well as ultrasound examination pre- and post-alloHSCT. The application of this protocol was feasible in clinical practice and achieved a high inter- and intra-rater reliability. In our population, no case of SOS was identifiable and, in line with previous studies, no changes known to be associated with SOS were detected by ultrasound examination in our cohort. Additionally, we investigated subgroups of patients partly fulfilling SOS diagnostic criteria analyzing correlations between the fulfilled criteria and aberrances in ultrasound measurements pre- and post-alloHSCT. Although statistical examination may be limited by a small sample size and missing SOS cases, hyperbilirubinemia, thrombocytopenia and weight gain showed only a coincidence with selected, enlarged liver dimensions in few patients. This may underline the fact that hepatomegaly occurs as an unspecific finding after alloHSCT. Our protocol, including the ultrasound examination pre- and post-alloHSCT and laboratory parameters, may help to rule out SOS early, but validation in a greater population and different transplantation centers is required to warrant broader appliance. Nevertheless, we aim to contribute to an elaborate and standardized work-flow in peri-alloHSCT patient care.

AbstractFish is an essential source of high-quality protein for people worldwide. The present study was designed to compare the growth performance among the channel-blue hybrid catfish, channel catfish transgenic for the channel catfish growth hormone (ccGH) cDNA driven by the antifreeze protein promoter from an ocean pout Zoarces americanus (opAFP-ccGH), and non-transgenic channel catfish control. Mean body weight of channel-blue hybrid catfish was 15.80 and 24.06% larger than non-transgenic channel catfish control at 4 and 18 months of age, respectively. However, transgenic opAFP-ccGH channel catfish were 5.52 and 43.41% larger than channel-blue hybrid catfish and 22.19 and 77.91% larger than their controls at 4 and 18 months of age, respectively. Significant differences in mean body weight between the sexes within all genetic types were found. Males were larger than females (P < 0.001). However, mean body weight of non-transgenic males was not larger than transgenic opAFP-ccGH females or male and female hybrid catfish. Condition factor of transgenic opAFP-ccGH channel catfish was higher (P < 0.05) than that of full-sibling, non-transgenic channel catfish and hybrid catfish. The mean percentage body weight gain of GH transgenic channel catfish was 559%, the channel-blue hybrid catfish was 384.9% and their non-transgenic controls channel catfish was 352.6%.

Abstract Thermal barrier coating plays a vital role in protecting materials' surfaces from high-temperature environment conditions. This work compares the demeanour of uncoated and air plasma sprayed Cr3C2-25NiCr and NiCrMoNb coated X8CrNiMoVNb16-13 substrates subjected to air oxidation and molten salt (Na2SO4 + 60%V2O5) environment condition at 900°C for 50 cycles. Coating characteristics have been analyzed through microstructure, thickness, porosity, hardness, and bond strength. SEM, EDS and XRD analysis were used to analyze corrosion's product at the end of the 50th cycle. Coating microstructures showed a uniform laminar structure that is adherent and denser with a coating thickness of 150 ± 20 μm and porosity less than 3.5%. The Microhardness of both the coated substrates were higher than that of the bare substrate. Cr3C2-25NiCr and NiCrMoNb coating bond strength was 38.9 MPa and 42.5 MPa. Thermogravimetric analysis showed the parabolic rate law of oxidation for all the substrates in both environments. In the molten salt environment, all the substrates exhibited higher weight gain compared to the air oxidation environment. In both environmental conditions, the uncoated X8CrNiMoVNb16-13 alloy exhibited higher weight gain than the coated substrates. The formation of Cr2O3, NiO and spinel oxide NiCr2O4 offers good resistance to corrosion to all the substrates in both the environmental condition. However, the presence of Mo and Nb significantly accelerated the corrosion of the substrate, thereby increasing the weight of the NiCrMoNb substrate. It is observed that Cr3C2-25NiCr and NiCrMoNb coating over the X8CrNiMoVNb16-13 substrate significantly protected the substrate against the hot corrosion than the bare alloy exposed to similar environmental conditions.

The summer months have recently been identified as a time of the year when children gain excess weight. Despite contrary beliefs, youth are more susceptible to weight gain and fitness losses during this time. Summer camps have been identified as a possible solution to reduce declines in overall health during these months. The purpose of this study was to establish expected step counts and moderate to vigorous physical activity (MVPA) values for a variety of activities in one residential camp. Participants included 188 campers (M age = 8.7). Sessions included a variety of invasion, target, net/wall and fitness activities. Step counts and MVPA were tracked across 51 days, incorporating 839 activity sessions using a NL–1000 (New Lifestyle Inc., Lee Summit, MO, USA) accelerometer to track campers’ activity. Means and steps/minute were calculated for each activity. Invasion games represented the greatest opportunity for campers to engage in physical activity. Findings are useful for researchers and practitioners to evaluate physical activity and MVPA at camp settings.

Background: Premature and low birth weight (LBW) infants are at increased risk of having inadequate growth in post-discharge periods. In this study, lyophilized human milk was used as an immune-nutrition supplement along with breastfeeding for a period of 1 month in preterm infants discharged from neonatal intensive care unit (NICU). Objectives: Primary objective was to assess the percentage change in serum immunoglobulins for the duration of supplementation, and secondary objectives were to correlate changes in immunoglobulins to number of episodes of infections including respiratory infections and diarrhea, requirement of antibiotics, weight gain, and episodes of feed intolerance during the study period. Methods: A total of 10 preterm and LBW infants were included in the study at the time of discharge from NICU after satisfying the inclusion and exclusion criteria. The serum immunoglobulins were estimated at baseline and at end of the study, other parameters such as episodes of infections, feed intolerance, and weight gain were recorded on the weekly follow-up visits. All the infants received supplementation with NeoLact 70 – 1.55 g on a TID frequency along with the regular breastfeeding for a period of 1-month post-discharge from NICU and were followed up on a weekly basis. Results: Ten infants completed the study, mean birth weight and gestational age were 1779.4±576 gm and 33.5±4.9 weeks, respectively. There was increase in immunoglobulins IgA, IgE, IgG, and IgM by 38.29%, 85.36%, 17.45%, and 48.25%, respectively, from baseline to end of study. None of the infants experienced feeding intolerance, diarrhea, abdominal distension, fever, respiratory infections, or rehospitalizations, none of the infants required antibiotics or probiotics during the study period. The average weight gain in the 1st, 2nd, 3rd, and 4th week of supplementation was 28.42 g/day, 31.57 g/day, 35.17 g/day, and 39.24 g/day, respectively, with a mean weight gain of 30.4 g/day achieved for the entire duration of the study. Conclusion: The immune-nutritional supplementation with lyophilized human milk (NeoLact 70 – 1.55 g) helps to ensure exclusive human milk diet post-discharge and reduce the risk of infections, diarrhea, and rehospitalization through the enhancement of immunoglobulins and ensuring optimal weight gain. However, these results should be confirmed through multicentric studies with larger sample size. Supplementation with NeoLact 70 – 1.55 g can clinically benefit premature and LBW infants post-discharge.
