Since skin is the first organ that come into contact with the surrounding, the habitat of the species should be related to the properties of the frogs’ skin. Thus, we investigated the O. hosii skin histology in relation to water quality parameters at different localities in Sarawak. The goal of study is to uncover a link between O. hosii habitat and its skin histology at four different locations: Ranchan Recreational Park (RRP), Matang Wildlife Centre (MWC), Borneo Highlands (BH), and Santubong National Park (SNP). The water quality criteria for each area were pH, turbidity, temperature, and dissolved oxygen (DO). The results showed that DO concentration of the habitat is the most essential element in affecting the health of the amphibian skin, as well as the forested areas (MWC, SNP, and BH) that protect the skin from direct sunlight. The DO of the habitat differed significantly for the mean number of mucous and seromucous glands at 0.01 (α = 0.05) and 0.03 (α = 0.05), respectively. The number of mucous glands and DO were found to have a strong positive correlation at 0.701. However, the number of seromucous glands showed a strong negative correlation with DO at -0.623. O. hosii skin from the four different localities was found to have cutaneous gland variations that reflect the environment in the number of glands. Mucous glands play an important role in indicating the localities’ water quality, which reflects adaptation of O. hosii to its habitat. This highlights the importance of preserving natural habitats for this sensitive species.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139159697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moringa oleifera has been used traditionally to treat anxiety. However, there is still lack of understanding on the mechanism for its anxiolytic effect. The purpose of this study was to investigate the anxiolytic effects and the mechanism of ethanolic extracts of the leaves of M. oleifera (MOLE) by observing behavioural changes of the Danio rerio and the differential gene expression analysis using custom RT2 Profiler PCR array. A 14-day chronic behaviour study was conducted using three concentrations of MOLE (500 mg/L, 1000 mg/L and 2000 mg/L) fluoxetine as the positive control. Stress-induced D. rerio treated with 1000 mg/L MOLE showed the lowest level of anxiety compared to other groups as evidenced by a decrease in freezing episodes and freezing time, increased entries into the light region. The fish also showed significant changes in the expression of crhb, faah2a, mao, and pah genes. MOLE with the presence of quercetin and kaempferol are believed to exert its anxiolytic effects through differential expression of gene (i) modulating the function of GABAA receptor (crhb), (ii) inhibiting the expression of nitric oxide synthase (NOS) and the production of nitric oxide, (iii) increasing the AEA levels in the brain (faah2a), (iv) increasing the level of dopamine levels in the brain (mao). These findings provide valuable insights into the potential use of MOLE as a treatment for anxiety-related disorders as well as the significance of the molecular pathways involved in its anxiolytic properties.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139159749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This spice contains abundant bioactive compounds that are capable of enhancing human health. However, the prebiotic potential of P. nigrum L. as a food ingredient has not yet been explored. Therefore, this research studied P. nigrum L. through in vitro gastrointestinal digestion and colonic fermentation using human faecal slurry. Samples were analysed for the colonic bacterial changes and its metabolites production using HPLC. Both black and white pepper showed prebiotic responses similar to those in inulin, particularly in stimulating the growth of human gastrointestinal microbiota. This study finds that P. nigrum L. promotes the growth of probiotic strains such as Bifidobacterium spp., and Lactobacillus / Enterococcus. Both black and white pepper also showed the ability to suppress colonic pathogen strain like Clostridium histolyticum. In vitro colonic fermentation of P. nigrum L. also significantly stimulate production of health beneficial metabolites. The production of short-chain fatty acids like acetate and propionate were observed to be particularly abundant. This is the contribution of piperine in both black and white pepper. In which, piperine provide both anti-bacterial and anti-inflammatory properties. Overall, P. nigrum L. showed appreciable prebiotic value similar to the commercial prebiotic, inulin. Thus, black and white pepper from Sarawak, Malaysia helps in promoting human gastrointestinal health. This finding may contribute to the value-added of Sarawak pepper as a functional food that can be involved in daily meals as spices.","PeriodicalId":32107,"journal":{"name":"Borneo Journal of Resource Science and Technology","volume":"2017 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139160052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their small size and unattractive appearance, dung beetles play an important role in the ecosystem, and they are widely recognised as one of the most effective bioindicators of ecosystem health. Although there has been an increase in dung beetle studies in Peninsular Malaysia, there are very few ecological studies of dung beetles conducted in Sarawak, despite being the largest state of Malaysia. Therefore, this study aims to provide recent information on the distributions of dung beetles from the genus Onthophagus in Sarawak. A total of 32 occurrences data for eight selected Onthophagus species representing 11 localities were successfully recorded. All analyses were performed using the Maximum Entropy Modelling Version 3.4.4 (MaxEnt) and Quantum Geographic Information Systems 3.28.2 (QGIS) software. It is revealed that most dung beetles’ distributions are strongly influenced by temperature and precipitation which suggests its capabilities as a bioindicator to identify high biodiversity areas.

This species has scant of scientific formation particularly on population parameters like growth, mortality and recruitment. The present study aimed to estimate the body indices and population parameters of Setipinna breviceps of Batang Lassa Estuary (BLE). Samples were collected between April 2019 and September 2020. A local made bag net known as Gnian (mesh size 1.25 to 4.00 cm) was used for sampling the fish. A total of 287 qualified specimens were used for this study. The length and weight of individual fish was measured to the nearest 0.1 cm and 0.01 g, respectively. The length ranged from 5.50 to 24.00 cm and growth coefficient (b) was 2.563 (R2 = 0.87) which clearly indicated a negative allometric growth. About 50% of individuals showed flat or slender body (Kn<1) and 47% of the specimens were rounded shaped (Kn>1) while 2.44% of fishes measured an ideal shape (Kn = 1). The parameters of growth L∞, K and ϕ’ were estimated at 24.15 cm, 0.23 yr-2 and 2.13, respectively. The estimated natural mortality and fishing mortality were 0.74 and 0.29 yr-2, respectively and exploitation rate was 0.28. The recruitment pattern during the study was observed at two possible unequal peaks. The present study concluded that the anchovy was under exploited (E<0.5) as demonstrated by the under-sized fishes caught with small mesh size net. However, considering the minimum lengths and length at first catch, the BLE could be a productive nursery ground for S. breviceps.
