Abstract. This study was conducted to determine the current prevalence of nematode infections in small ruminants and the management of farms in Terengganu, Malaysia. A total of 267 faecal samples from sheep and goats were collected and examined by the Modified McMaster method, larval culture and third stage larva identification. Results revealed that the worm egg count (WEC) for nematode infections ranged between 0–26,800 e.p.g. and the distribution of the WEC was different between farms (χ2 (15) = 165.72, p<0.05). Haemonchus contortus was the dominant species observed (75.0%), followed by Trichostrongylus sp. (24.0%) and Oesophagostomum sp. (1.0%) (χ2(2, N=100)=86.06, p<0.05). The schedule for grazing management, limited grazing area and extensive usage of anthelminthic could have been the main influences of nematode infections to be severe in small ruminants. The results obtained from this study will update the status of nematode infection in small ruminants in Terengganu. This information will help the farmers and the Department of Veterinary Services to plan on treatment and management to improve the animals’ health.

The expression profiles of inflammatory cytokines viz. interleukins (IL)-6, IL-8, IL-12, granulocyte macrophage-colony stimulating factor, interferon-gamma and tumor necrosis factor-alpha in response to subclinical mastitis in indigenous cattle breed Kankrej (n = 6), Gir (Bos indicus) (n = 12) and crossbred (Bos taurus x Bos indicus) (n = 7) were investigated using quantitative real time PCR. Significant correlation (p < 0.05) was observed between total bacterial load and somatic cell count (SCC) in all three breeds of cattle. All the cytokines were observed to be up-regulated compared to cows with healthy quarters, however, level of their expression varied among three breeds of cattle. In Kankrej most cytokines were found to be transcribed to higher levels than in other two breeds; the milk had higher load of bacteria but not so high SCC, implying that Kankrej has a higher inherent resistance against mastitis. The results of present study indicated that mammary glands of crossbred cattle are more sensitive to bacterial infection than indigenous breed of cattle as they elicit immune response at lower bacterial load and result into higher SCC. Research on identification of factors responsible for differentially expressed cytokines profiles and use of cytokines as immunomodulatory tools can pave way for formulating control strategies against bovine mastitis.

Objective: To explore the antiproliferative activity and apoptosis in cells caused by active compounds present in plants using different techniques. Methods: We investigated the antiproliferative effects of methanolic extracts from different parts of seven plants on A-549 (lung cancer) cells and primary cell culture (chick embryo fibroblast cells, as normal cells) using MTT assay and the potent plant was fractioned further. All these fractions were screened again for anti-proliferative activity. DNA fragmentation and DAPI staining were used to study apoptosis. Quantitative real-time was used to investigate the expression of apoptotic-related genes. LC-MS and

Objective To evaluate the anti-obesity activity of bixin (BIX) on C57BL/6J mice which were fed a high-fat diet (HFD) and to determine the mechanism of this effect. Methods C57BL/6J mice were separately fed a high-calorie diet or a normal diet for 8 weeks, then they were treated with BIX for another 13 weeks. After administration for 13 weeks, the animals were sacrificed. Body adiposity, serum lipid level, and insulin resistance were evaluated. In addition, a histological assay of pancreas and liver, an evaluation of the inhibitory properties on pancreatic lipase, and α-amylase were conducted. Results Administration of BIX significantly decreased the body weight gain, adipocyte size, fat pad weights, hepatic lipid levels in HFD-induced obese mice. In addition, reduced liver weight exhibited decreased serum leptin levels, malic enzyme, glucose-6-phosphate dehydrogenase, hepatic fatty acid synthase, aspartate aminotransferase, alanine aminotransferase and hepatic phosphatidate phosphohydrolase activity. However, superoxide dismutase, catalase, glutathione peroxidase, and glutathione levels were increased in hepatic tissue. BIX also decreased lipid and carbohydrates absorption due to inhibition of pancreatic lipase and α-amylase. Long term supplementation of BIX significantly decreased hyperlipidemia, insulin resistance and glucose level. Decreased levels of hepatic steatosis and the islets of Langerhans appeared less shrunken in HFD-fed mice. Conclusions The antiobesity effect of BIX appears to be associated at least in part, to its inhibitory effect on lipids and carbohydrate digestion enzymes such as pancreatic lipase, α-glucosidase, and α-amylase. The results suggested that BIX also act as an antioxidant and may treat visceral obesity normalizing glucose levels, improving insulin resistance and increasing energy expenditure. Therefore, achiote which has a main component, the carotenoid BIX, could be a viable food for the treatment of obesity and diabetes.

Background: and Purpose We compared the outcomes of endovascular therapy (EVT) in an extended time window in patients with large-vessel occlusion (LVO) between patients with and without pre-stroke disability. Methods: In this prespecified analysis of the multinational CT for Late Endovascular Reperfusion study (66 participating sites, 10 countries between 2014 and 2022), we analyzed data from patients with acute ischemic stroke with a pre-stroke modified Rankin Scale (mRS) score of 0–4 and LVO who underwent EVT 6–24 hours from the time last seen well. The primary outcome was the composite of functional independence (FI; mRS score 0–2) or return to the pre-stroke mRS score (return of Rankin, RoR) at 90 days. Outcomes were compared between patients with pre-stroke disability (pre-stroke mRS score 2–4) and those without (mRS score 0–1). Results: A total of 2,231 patients (median age, 72 years; median National Institutes of Health Stroke Scale score, 16) were included in the present analysis. Of these, 564 (25%) had pre-stroke disability. The primary outcome (FI or RoR) was observed in 30.7% of patients with pre-stroke disability (FI, 16.5%; RoR, 30.7%) compared to 44.1% of patients without (FI, 44.1%; RoR, 13.0%) (P<0.001). In multivariable logistic regression analysis with inverse probability of treatment weighting, pre-stroke disability was not associated with significantly lower odds of achieving FI or RoR (adjusted odds ratio 0.73, 95% confidence interval 0.43–1.25). Symptomatic intracranial hemorrhage occurred in 6.3% of both groups (P=0.995). Conclusion A considerable proportion of patients with late-presenting LVO and pre-stroke disability regained pre-stroke mRS scores after EVT. EVT may be appropriate for patients with pre-stroke disability presenting in the extended time window.
