The study aimed to explore the effects of Nigella sativa oil (NSO) or thymoquinone (TQ), alone or in combination with dexamethasone (DEX), on the development of bleomycin (BLM)-induced PF. Forty-two male rats were divided into seven groups: Control (CTRL); BLM, received a single dose of BLM on day 0, intratracheally; all remaining groups received BLM, as well. DEX, received DEX daily, intraperitoneally, 1 day before BLM and continued for 14 days; NSO and TQ groups, received daily NSO and TQ, respectively, 7 days before BLM and continued for 35 days; DEX + TQ, received both DEX and TQ; DEX + NSO, received both DEX and NSO. At the end, lung tissues were used for histopathological and biochemical analyses. BLM significantly increased the severity of fibrosis and inflammation compared to the CTRL. Bleomycin also significantly increased the amount of hydroxyproline, however, decreased most antioxidant enzymes in the lung tissue compared to the other groups. Group TQ + DEX significantly reduced the severity of BLM-induced PF as well as alterations in biochemical parameters, lung weight and O2 saturation. Nigella sativa oil slightly reduced BLM-induced PF, however, it caused non-significant hyperemia in lung tissue. Thymoquinone potentiated the effects of DEX on most biochemical and pathological alterations of BLM-induced lung injury much better than NSO. More studies are needed to support the use of NSO and TQ as potential protective agents against PF.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 11","pages":"613-620"},"PeriodicalIF":0.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11725293/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142980083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, cancer cell resistance has limited its anti-tumor efficacy. Some molecules called microRNAs (miRNAs), acting like fine-tuned switches, can influence how breast cancer develops and spreads. We conducted a study to examine if augmenting breast cancer cells with a particular molecule, known as miRNA-142-3p, could improve the efficacy of a widely used treatment called DTX. The expression level of miR-142-3p was initially assessed in MDA-MB-468 cells. The miRNA transfection was performed to conduct additional experiments. The impact of a combined treatment involving DTX and miRNA-142-3p on both cell migration (by wound healing assay) and apoptosis (using annexin V/Propidium iodide staining) was examined. Cell viability was determined through the MTT assay, and gene expression was quantified using quantitative real-time polymerase chain reaction. The combined application of DTX and miRNA-142-3p resulted in a significant decrease in the expression of factors promoting tumor growth, such as SOX2, Octamer 4, HMGA2, Kruppel-like factor 4, and Bach-1. Additionally, the combination of miRNA-142-3p and DTX initiated apoptotic cell death. Moreover, the progression of breast cancer cells was impeded by inducing cell cycle arrest at the G1 phase. This combination also efficiently restrained the migration and invasion of breast cancer cells. The DTX or miRNA-142-3p alone can suppress malignant behavior and progression of breast cancer cells, but their combination elicits a synergistic effect that further enhances breast cancer inhibition. In summary, miRNA-142-3p transfection can be administered in conjunction with DTX therapy to enhance its cytotoxicity against breast cancer cells and prevent chemoresistance.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 11","pages":"629-643"},"PeriodicalIF":0.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11725297/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142980007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rose Bengal plate test, standard agglutination test, and indirect enzyme linked immunosorbent assay tests were used to confirm all seropositive animals. A total number of 1,311 bovine samples from seropositive animals including were collected from 224 farms in 21 provinces of different regions of Iran and examined. The discovered Brucella isolates were phenotyped and molecularly characterized. The isolates were all B. abortus or B. melitensis. Bacteria analysis revealed that 70.53% of seropositive farms were tested positive for Brucella strains, predominantly B. melitensis biovar 1 (43.42%) and B. abortus biovar 3 (27.11%). Geographical distribution revealed that B. melitensis biovar 1 was the most common in dairy cow farms (16 provinces), followed by B. abortus biovar 3 (six provinces). Also, the prevalence of B. melitensis biovar 2, B. melitensis biovar 3, B. abortus biovar 1, B. abortus biovar 2 and RB51 vaccine were restricted to certain provinces. AMOS (abortus melitensis ovis suis)-polymerase chain reaction and Bruce-ladder PCR confirmed species identification.

The 20.00 µmol EGCG and a method two significantly affected the amending oxidative conditions as well as an increase in total antioxidant capacity and a decrease in malondialdehyde. The effect of EGCG in both concentrations was more on method two. The desired impact on sperm motility, viability, inhibition of lipid peroxidation and sperm DNA damage was observed in EGCG groups compared to control groups.

Cells had fibroblast-like morphology, plastic-adherent, expressed specific markers of MSCs and multilineage differentiation potential. The growth rate of cells from day 19th embryos was higher than from other ages. Moreover, cells expressed markers of pluripotency such as Nanog, PouV, Sox2, CVH, DAZL, and KIT, known for their role in maintaining stem cell self-renewal and pluripotency. As feeder cells, cbMSCs from three different ages promoted proliferation of H'Mong PGCs during co-culture.

A total number of 325 bovine milk samples (195 raw and 130 mastitic milk specimens) collected from Banaskantha, a milk-shed district of Gujarat, India, were included in the study. A total number of 27 K. pneumoniae isolates were recovered, consisting of 17 (62.96%) isolates from raw milk and 10 (37.03%) isolates from mastitic milk samples, giving an overall prevalence of 8.31%. Antibiotic sensitivity patterns revealed that 20 out of 27 isolates were found to be multi-drug resistant. Based on combination disc diffusion test and HiCrome ESBL agar method, 20 (74.07%) and 25 (92.59%) isolates were detected as ESBL producers, respectively. Among virulence genes studied, presence of wabG (25/27; 92.59%) was higher than kfuBC (5/27; 18.51%). Beta-lactamase genes viz., blaSHV, blaTEM and blaCTX-M-1 were detected in 23/27 (85.18%), 3/27 (11.11%) and 2/27 (7.40%) of isolates, respectively; while, none of the isolates was found to be positive for blaCTX-M-9 and blaOXA-1 genes. Outcome of the study provided an insight into virulence genes and ESBL producing K. pneumoniae isolated from bovine milk samples in India.","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"15 2","pages":"57-64"},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10924294/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140094768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
