Effect of Vegetable Waste on Growth Performance and Hematology of Broiler Chicks.

Vegetable waste (spinach, potato, and cauliflower) is a rich and natural source of nutrients, potentially good for supplying minerals, essential amino acids, and antioxidants to the birds. Relatively, its cost very low, easily to accessible, easily process & pose little risk of illness. The aim of present study was to evaluate the effect of vegetable waste (VW) as feed supplement on growth performance and hematology of broiler chicks. For this purpose, a total of 200 (4 days old) vaccinated chicks were acquired from a commercial hatchery Multan which was acclimated for three weeks (21 days) on basal starter feed after that 25-day-old chicks with uniform body weight were allocated according to a CRD (completely randomized design) into four dietary treatments with three replicates of each contained 15 chicks in 12 pens. In dietary treatments, chicks were feed with basal feed (BF) and supplemented feed with vegetable waste (VW) of spinach, potato, and cauliflower. For this purpose, the dietary treatments included control treatment (T 1) (100% BF+0% VW) and other dietary treatments (T 2) (75% BF+25% VW), (T 3) (50% BF+50% VW), and (T 4) (25% BF+75% VW). The body weight, feed intake, food conversion ratio (FCR), and mortality were checked on weekly and daily basis. For hematology analysis, after the 1st experimental week (25-day-old chicks) and the last 5th experimental week (56-day-old chicks), the samples of blood were gathered from the wing's veins of two birds from each treatment in random way. At the end of five weeks (35 days), birds with uniform average body weight were selected per treatment with three replicates (2 bird/replicate) and then were manually slaughtered according to the Halal method to analyze the weight of internal body organs of broilers by physical and statistical analysis (ANOVA). There was no significant effect (P > 0.05) on feed intake and FCR among all the dietary treatments. But in average, body weight and BWG were higher in treatment (T 2) (P < 0.01) than all other dietary treatments (T 3) and (T 4) and control treatment (T 1). The blood constituents in this study showed that broilers in control treatment (T 1) and other dietary treatments (T 2), (T 3), and (T 4) fed on different doses were significantly (P < 0.01) different from each other. The week 5 (W 5) shows higher values of blood constituents (P < 0.01) than week 1 (W 1). The carcass yield of the chicks fed on different doses showed that they were significantly different (P < 0.01) among the dietary treatments. The VW inclusion 0%, 25%, 50%, and 75% had positive effect on blood constituents and carcass yield of the broiler chicks; they were significantly (P < 0.01) different among the treatments.

Toxicological Effects of Sewage Water on Chick Embryonic Development.

For toxicity research, a total of 100 fertilized nonincubated eggs were used for this study. There were two trials in this experiment which were further divided into 2 phases based on a different days of sewage water treatment and observation days. In each trial, 50 eggs were used and divided into 5 groups. Group A, B, and C were treated with three different concentrations of pure and diluted sewage water (100%, 70%, and 30%), respectively. Control group D was given 0.3 ml saline solution (0.9% NaCl) and group E was uninjected. Different parameters such as the embryo's body weight, body length, forelimb length, hindlimb length, and head diameter were determined. In trial 1, eggs were treated with sewage water on 7th day of incubation and opened on 8th day (phase I) and 9th day (phase II). When the trial 1 (phase I) findings were compared to the control groups, it was observed that body weight, body length, forelimb length, and hindlimb length were highly statistically significant differences (p < 0.01), but the head diameter was not significant (p > 0.05). Phase II result showed embryo's head diameter was a highly statistically significant difference (p < 0.01), whereas forelimb length was significant (p < 0.05), and body weight, body length, and hindlimb length were nonsignificant (p > 0.05). In trial 2, eggs were treated with sewage water on 14th day of incubation and opened on 15th day (phase I) and 16th day (phase II). Results of 15th day showed a highly statistically significant (p < 0.01) difference in hindlimb length, while body weight, body length, forelimb length, and head diameter were nonsignificant (p > 0.05). Phase II of trial 2 showed that on 16th day, body weight, body length, forelimb length, hindlimb length, and head diameter showed a nonsignificant (p > 0.05) difference between experimental and control groups. Embryos were observed to be deforming on the 9th day (after 48 hours of exposure to sewage water). Other phases showed no signs of deformation. Except on 8th day of incubation, dose-related mortalities were present in experimental groups, while the control group showed no mortality.

Eriocalyxin B induces apoptosis in human triple negative breast cancer cells via inhibiting STAT3 activation and mitochondrial dysfunction.

Eriocalyxin B (EriB), a potent ent-kaurene extracted from Isodon eriocalyx, has turned up as novel anti-cancer agent during recent years against a range of cancer types. TNBC (Triple negative breast cancer) is highly aggressive breast cancer, which is resistant towards current therapeutics due to absence of drug targets. Here, we have probed the molecular mechanism of EriB-induced apoptosis in TNBC (MDA-MB231) cells to check whether its anticancer activity is mediated by modulation of STAT3 and NF-Ï°B. EriB induced apoptosis in MDA-MB231 cells via inhibiting NF-Ï°Bp65, STAT3 phosphorylation, increasing Bax/Bcl-2 ratio, MMP dissipation, and activation of caspase-3. These results provide a rationale for further in vivo investigations on EriB, which might also prove to be a potential drug candidate for developing novel therapeutics against TNBC.

INSECTICIDE RESISTANCE IN THE GROUND SPIDER, Pardosa sumatrana (THORELL, 1890; ARANEAE: LYCOSIDAE).

Elevated levels of insecticides detoxifying enzymes, such as esterases, glutathione S-transferases (GSTs), and cytochrome P-450 monooxygenases, act in the resistance mechanisms in insects. In the present study, levels of these enzymes in the insecticide-resistant ground spider Pardosa sumatrana (Thorell, 1890) were compared with a susceptible population (control) of the same species. Standard protocols were used for biochemical estimation of enzymes. The results showed significantly higher levels of nonspecific esterases and monooxygenases in resistant spiders compared to controls. The activity of GSTs was lower in the resistant spiders. Elevated levels of nonspecific esterases and monooxygenases suggest their role in metabolic resistance in P. sumatrana. The reduced levels of total protein contents revealed its possible consumption to meet energy demands.
