Niacin is one of the B-complex vitamins that play an important role in metabolic pathways, while ubiquinone (Coenz-Q) is a component of the electron transport chain required for energy production. This study evaluated the role of niacin combined with ubiquinone in the inhibition of lipoprotein lipase as a mechanism of anti-obesity and antiatherogenic agents in rats fed on a High-Fat Diet (HFD). To achieve this purpose, sixty male albino rats (100– 150 g) were used in this study and divided into six groups (10 each). Group I (control): rats fed on a normal diet. Group II: Rats fed on HFD. Group III: Rats fed HFD and were given Niacin at 10 mg/kg body weight (b.w)/day orally by stomach tube. Group IV: Rats fed HFD and were given Coenz-Q (10 mg /kg b.w/day) orally. Group V: Rats fed HFD were given Niacin (10 mg/kg b.w/day) and Coenz- Q (10 mg /kg b.w/day). Group VI: Rats were given a hypocholesterolemic agent (cholerose) orally (10 mg/kg b.w/day) as positive control. The obtained results showed that treatment with Niacin or Coenz-Q or combined increased the activity of lipoprotein lipase (p < 0.001) and reduced the atherogenic effect and obesity index (p<0.001). The combined treatment is more effective than individual one or cholerose. In conclusion, Niacin combined with Coenz- Q increased lipid clearance and prevented its accumulation in blood. This combination is promising as antiatherogenic agent. Further investigation is required to identify the pathways regulated by these supplements that help in weight management.

Reactive oxygen species play a significant role in the pathogenesis of retinopathy in diabetes patients. The current study aimed to assess the effect of ethyl acetate extract (EAE) from Balanites aegyptiaca (10, 25 or 50 mg/kg b.w.) in experimental diabetic rats. To achieve this aim, five groups of male rats were included: control, diabetic, and diabetic rats treated with 10, 25, and 50 µg/kg b.w. of EAE for eight weeks. Our results suggests a protective role of EAE against oxidative stress induced by streptozocine. EAE treatment produced a reduction in blood glucose levels, HbA1c, malondialdehyde and vascular endothelial growth factor (VEGF) in diabetic retina (p < 0.001), as well as an enhancement in antioxidant capacity against streptozocine-induced oxidative stress. Tumor necrosis factor alpha (TNF-α), interleukin (IL-1β) and vascular endothelial growth factor (VEGF) were significantly reduced in diabetic rats treated with EAE, compared with untreated diabetic rats. Analysis of EAE by GC-MS indicated the presence of β-sistosterol. Overall, EAE modulates oxidative stress induced by streptozocine and enhances antioxidant activity, which may provide additional endothelial protection in retina of diabetic rats. These results hold great promise in the management of diabetic complications.

Impact of sporadic reporting of poultry Salmonella serovars from selected developing countries
2015
This review documents the sporadic reporting of poultry Salmonella serovars in South Africa, Egypt, Indonesia, India, and Romania, five countries selected based on the importance of their distribution in different regions of the world and their cumulative significant population size of 1.6 billion. South Africa reported contamination of its poultry carcasses by S. Hadar, S. Blockley, S. Irumu, and S. Anatum. Results from Egypt showed that S. Enteritidis and S. Typhimurium were predominant in poultry along with other non-typhoid strains, namely S. Infantis, S. Kentucky, S. Tsevie, S. Chiredzi, and S. Heidelberg. In Indonesia, the isolation of Salmonella Typhi was the main focus, while other serovars included S. Kentucky, S. Typhimurium, and S. Paratyhi C. In India, S. Bareilly was predominant compared to S. Enteritidis, S. Typhimurium, S. Paratyphi B, S. Cerro, S. Mbandaka, S. Molade, S. Kottbus, and S. Gallinarum. Romania reported two Salmonella serovars in poultry that affect humans, namely S. Enteritidis and S. Typhimurium, and other non-typhoid strains including S. Infantis, S. Derby, S. Colindale, S. Rissen, S. Ruzizi, S. Virchow, S. Brandenburg, S. Bredeney, S. Muenchen, S. Kortrijk, and S. Calabar. The results showed the spread of different serovars of Salmonella in those five developing countries, which is alarming and emphasizes the urgent need for the World Health Organization Global Foodborne Infections Network (WHO-GFN) to expand its activities to include more strategic participation and partnership with most developing countries in order to protect poultry and humans from the serious health impact of salmonellosis.

The aim of this research is to appraise a newly patented method for control of chicken coccidiosis in comparison to a classical approach. The new method implements an invented Disinfectant (WSD) for decontamination of rearing surfaces, and a developed drinking water-herbal coccidiostat (EOBWE) supplement. The experimental design has 8 treatments (TRTs), with four pens/TRT, and 25 broiler chicks/pen. The floors of TRT1 to TRT7 are contaminated with 4.0 × 10

of each of E. acervulina, E. maxima, and E. tenella, while TRT8-floor is left uncontaminated. The floors of TRTs 1 and 2 are disinfected with chlorine, while that of TRTs 3-6 are disinfected by WSD. Floors of TRTs 7 and 8 are deprived of disinfection. Birds in TRTs 1, 6, 7, and 8 are deprived of coccidiostat, while birds in TRTs 2 and 3 are fed salinomycin in their feed; birds of TRT 4 are administered EOBWE in drinking water, while birds of TRT 5 are administered simultameously both, the salinomycin and EOBWE. Birds in TRT 4 (WSD/EOBWE treated) and TRT 5 (WSD/salinomycin + EOBWE) had improved protection (lowest oocyst output and intestinal lesions) and enhanced production (lowest mortality, lowest feed conversion ratio, and highest live body weight) compared to the other five challenged treatments, associated with significant improvements compared to positive controls (TRT 7) (P < 0.05).

Cancer response to chemotherapeutic agents and its side effects remain a challenge for the development of new anticancer compounds. Dates are consumed worldwide due to their high nutritional value. We investigated the cytotoxicity and expression of the proapoptotic BAX gene in human hepatocellular carcinoma (HepG2) cells treated with Ruthana date ethanolic extract (RDE). The RDE ingredients analyzed by GC/MS and HepG2 cells were treated with different concentrations of RDE for 24, 48, and 72 h. Cytotoxicity, cell viability, DNA fragmentation, and BAX expression were determined. The GC/MS analysis of RDE showed its high content of quercetin, myricetin kaempferol, thymine, and catechol as the most active ingredients. HepG2 treated with RDE showed a significant change in morphological characteristics related to cell death. The antiproliferative activity determined by WST-1 demonstrated that RDE significantly reduced cell viability. Cells treated with RDE (10-60 mg) showed gradual DNA fragmentation in a dose-dependent manner. Gene expression analysis showed upregulation of BAX at 30 mg/ml of RDE (p < 0.001). However, it showed downregulation at (40-60 mg/ml) as compared to control. Our findings indicated that RDE exert cytotoxicity against HepG2 cells due to its high content of flavonoids. This effect through DNA fragmentation and activation of the proapoptotic BAX gene.

Metagenomic Analysis of Antibiotic-Induced Changes in Gut Microbiota in a Pregnant Rat Model
2016
Food and Drug Administration (FDA, USA)-approved category B antibiotics are commonly prescribed to treat infections during pregnancy. The aim of this study was to investigate antibiotic-induced changes in gut microbiota (GM) that occur during pregnancy. The 16S rRNA amplicon deep-sequencing method was used to analyze the effect of category B antibiotics (azithromycin, amoxicillin and cefaclor) on GM during pregnancy using a rat model. The GM composition was substantially modulated by pregnancy and antibiotics administration. Firmicutes, Bacteroidetes, Proteobacteria, Chlamydiae, Actinobacteria, and Cyanobacteria were the dominant phyla. Antibiotic treatment during pregnancy increased the relative abundance of Proteobacteria and reduced Firmicutes. The genera Shigella, Streptococcus, Candidatus Arthromitus, and Helicobacter were significantly (p < 0.05) more abundant during pregnancy. Antibiotics significantly (p < 0.05) reduced the relative abundance of Lactobacillus but increased that of Enterobacter. There was a significant (p < 0.05) decrease in Lactobacillus sp., Lactobacillus gallinarum and Lactobacillus crispatus during pregnancy. Antibiotic treatment reduced bacterial diversity; the lowest number of operational taxonomic units (OTUs) were detected in the cefaclor-treated groups. Antibiotics significantly (p < 0.05) promoted weight gain during pregnancy, and increased relative abundance of Shigella sonnei, Enterococcus hormaechei, and Acinetobacter sp. GM perturbations were accompanied by increases in Proteobacteria abundance and weight gain in pregnancy following antibiotic treatment.

Introduction: Avian influenza viruses of the H9N2 subtype have been reported to cause human infections. This study demonstrates the impact of nasal viral passaging of avian H9N2 in hamsters on its cross species-pathogenic adaptability and variability of amino acid sequences of the hemagglutinin (HA) and neuraminidase (NA) stalk. Methodology: Three intranasal passagings of avian H9N2 in hamsters P1, P2, and P3 were accomplished. Morbidity signs and lesions were observed three days post viral inoculation. The HA test was used for presumptive detection of H9N2 virus in the trachea and lungs of the hamsters challenged with the differently passaged viruses. Different primers were used for PCR amplification of the HA1 and NA stalk regions of the differently passaged H9N2 viruses, followed by sequence alignment. Results: The morbidity signs indicated low pathogenicity of the differently passaged H9N2 viruses in hamsters. The frequency of gross and microscopic lesions in the tracheas and lungs were insignificantly different among hamsters challenged with the differently passaged H9N2 viruses (p > 0.05). There was 100% similarity in the amino acid sequence of the HA gene of most passaged viruses. The amino acid sequence of the neuraminidase in the third passaged H9N2 virus recovered from lungs showed a R46P mutation that might have a role in the pathogenic adaptability of P3 viruses in hamsters’ lungs. Conclusions: The apparent adaptation of avian H9N2 virus to mammalian cells is in agreement with the World Health Organization’s alertness for a possible public health threat by this adaptable virus.
