Humans can be infected by leptospires through direct contact with infected animals or indirect contact with leptospires contaminated water or soil. Outbreaks of leptospirosis usually occur after heavy rainfall and flooding, particularly in endemic areas. The aim of this study was to detect the presence of leptospires in water and soil in livestock farms after a massive flood in Kelantan. Samples were collected from 28 livestock farms in Kelantan, comprising 62 water samples and 62 soil samples, respectively. The samples were filtered and inoculated into a semisolid EMJH medium containing 5-FU for the isolation of Leptospira spp. The Leptospira spp. isolates were then identified using classical methods (1M NaCl, 8-azaguanine, and 13 °C), serology (MAT), multiplex polymerase chain reaction (mPCR), and DNA sequencing. The classical identification methods showed varying results and failed to differentiate between pathogenic and non-pathogenic leptospires. MAT showed the isolates reactions against serovars Autumnalis, Hebdomadis, Pyrogenes, Bataviae, Patoc, and Wolffii. However, mPCR showed that all isolates were non-pathogenic Leptospira spp. Further identification using DNA sequencing found that all isolates were identified as Leptospira wolffii, an intermediate species of Leptospira. The presence of L. wolffii in water and soil provides evidence that this species is circulating in the environment and could potentially transmit to humans and animals.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49124292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oleh itu, kajian ini telah menilai corak pelepasan bahan aktif daripada nanozarah dan gel tersebut serta kesan kesitotoksikannya. Dalam kajian ini, kedua-dua bahan aktif ini telah dimasukkan ke dalam nanozarah kitosan (CSNPs) menggunakan kaedah gelasi ion dan kemudiannya dicampur ke dalam pembawa gel Pluronik F-127 (PF-127) pada kepekatan berbeza. CSNPs yang terhasil telah dioptimumkan untuk memperoleh zarah bersaiz kecil (301.3 ± 57.6 nm) dan cas permukaan yang tinggi (+23.7 ± 0.7 mV). Kebanyakan zarah adalah berbentuk sfera dengan keberkesanan pemerangkapan yang tinggi untuk Cur (86.8 ± 4.2%) dan DsiRNA (100.9 ± 52.5%).

A new robust cut-off point using the median and median absolute deviation for the tree heights to classify the potential outliers are proposed in this study. Experimental results from the simulation study suggest our proposed method is able to identify the presence of multiple outliers with very small probability of swamping and masking. Application in real data also shows that the proposed clustering method for this linear functional relationship model successfully detects the outliers, thus suggesting the method's practicality in real-world problems.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43633444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a pollutant that can adversely affect public health and the ecosystem. Following the issues raised, methylphenol extraction from Selangor rivers need to be done to avoid adverse consequences. In this study, solid phase extraction (SPE) combined with ultraviolet-visible spectroscopy (UV-Vis) detection at 271 nm was utilized to extract methylphenol from Selangor rivers. The challenges reported by applying the SPE technique was to identify the optimum conditions for extraction to guarantee effective recovery of the extracted methylphenol. Therefore, this research aimed to develop an extraction technique to extract methylphenol from Selangor rivers. In this study, 3 mL Supel Swift-HLB cartridges with bed weight of 60 mg were used as SPE cartridges. The optimum conditions for methylphenol SPE were 3 mL methanol as a conditioning solvent, 6 mL of pH 5 water sample with a contact time of 4 min with adsorbent bed was practiced during sample loading, 3 mL of acetonitrile as washing solvent, and 12 mL of acetone as the elution solvent. The concentrations of methylphenol detected at five different locations collected from Sungai Klang, Sungai Selangor, and Sungai Langat ranged from 5 to 6 mg L-1. SPE coupled with UV-Vis is an appropriate method for methylphenol extraction as it simplifies sample preparation, is time saving, and can achieve a high percentage recovery of methylphenol.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48621143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bakh. f. is widely known for its anti-inflammatory and anti-cancer properties. However, there are no previous studies about extracting and purifying protease enzymes from C. vespertilionisleaves. Therefore, this study was conducted to extract and optimise the purification of protease from C. vespertilionis leaves and characterise its anti-inflammatory properties. The optimisation was performed using different levels of ammonium sulphate saturation (20, 40, 60, 80 and 100%). Next, dialysis was carried out for the sample with the highest specific activity (16.88 U/mg), achieved with 100% ammonium sulphate saturation. At 100% saturation, C. vespertilionis leaves showed an increase in the specific activity to 20.06 U/mg after dialysis. The findings demonstrate the successful extraction and purification of C. vespertilionis protease (CVP) with a molecular weight of 48 kDa, as proven by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis. CVP also exhibited anti-inflammatory activity, with an inhibition of 45.6% in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and IC50 of 19.24 µg/mL. The HPLC test further confirmed the presence of gallic acid and quercetin compounds in C. vespertilionis, which cure inflammation. The results indicate that optimised CVP purification was achieved and its anti-inflammatory ability was proven.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42715670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being a greener and more economical material, amino acid-based deep eutectic solvents (AADES) have attracted interest in CO2 capture applications. In this paper, the effect of L-arginine (Arg) in binary AADES of arginine-ethylene glycol (Arg-EG) and ternary AADES of choline chloride-ethylene glycol-arginine (ChCl-EG-Arg) on adsorption of CO2 was studied. The solubility, basicity, and physicochemical characteristics were compared with the binary DES (ChCl-EG) before and after being impregnated into a silica gel (SG) via the wet impregnation method. The AADES/SG adsorbents were evaluated for CO2 sorption performance using an automated gas sorption analyzer at 100% CO2 loading and thermogravimetric analysis (TGA) at flue gas conditions (15% CO2/85% N2). Findings show the basicity and the nitrogen content (N%) of AADES/SG were increased as Arg was added and DES/AADES functional group peaks (amino, hydroxyl, alkyl groups) were observed after the impregnation. The CO2 sorption of 16.0 mg/g at 25 °C and 1 atm was achieved by 30% Arg-EG(1:8)/SG followed by 30% ChCl-EG-Arg (1:2:0.1)/SG (14.8 mg/g) and 30% ChCl-EG/SG(1:2) (14.5 mg/g) using an Autosorb iQ2 instruments with 100% CO2 loading. The CO2 uptake was increased almost linearly with increasing pressure and decreased with increasing temperature. The Arg-EG(1:8)/SG shows the highest selectivity toward CO2 than other sorbents with 8.10 mg/g adsorption for 1 h at 15% CO2 loading at 25 °C with higher thermal stability and surface area. Considering environmental, technological, and economic viewpoints, the Arg-EG(1:8)/SG can be explored more as a potential solid sorbent for CO2 capture.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44717189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this research was to test and evaluate the ability of clove oil nanoparticles produced from polyethylene glycol 6000 (PEG 6000) to control DBM utilizing a solid dispersion technique. Bioassay by leaf dip method in laboratory was used to test the lethal effect of clove oil nanoparticles (CO-NPs) on DBM. Clove oil nanoformulation was successful because it produced nanoparticles (179.98 nm in diameter) while maintaining high levels of the active component eugenol. Clove oil nanoparticles may increase clove oil's toxicity to DBM, seen from the LC50 value after 24 h of treatment.

Flow-cytometric analysis was performed on single cell suspension prepared from formalin fixed paraffin embedded tissue (FFPET) sections of HNSCC using anti-CD44 and anti-MDR1/ABCB-1 primary monoclonal antibodies. Immunohistochemical (IHC) staining was also carried out using both of these antibodies on HNSCC tissue sections mounted on super frosted glass slides. On immunohistochemical analysis, the mean IRS for CD44 and MDR1 were 8.6364 ±3.02114 and 1.5909 ±1.27674 respectively. When mean immune-expression scores of CD44 antibody and MDR1/ABCB-1 were compared with histological grades and subtypes of HNSCC, the relationship was found to be statistically insignificant. Interestingly, a strong statistical difference (p = 0.000) was observed when the mean score of subset of dysplastic squamous epithelial cells with characteristics of cell stemness (CD326+CD44+) was compared among different histological subtypes of HNSCC using flowcytometric analysis. While no statistically significant association was observed when the mean score for subset of dysplastic cells with potential of drug resistance (CD44+MDR1+) was compared among different histological subtypes of HNSCC. Although potential cancer stem cell marker CD44 and the multidrug resistance maker ABCB-1/MDR1 co-expressed in HNSCC but the proportion of CD326+CD44+ subset of tumour cells (potential cancer stem cells/CSCs) significantly correlates with least aggressive to more aggressive tumour subtypes.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41770307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These chemicals leach from polycarbonate plastics and epoxy resins into the environment when exposed to heat. Human exposure to these chemicals causes various health issues; hence, the detection of BPA and PAEs has become more sensitive, and thus it is the most important environmental issue to be reduced due to consequences on human health. This research aimed to determine the optimum parameter of extraction process for BPA and PAEs from water samples by using deep eutectic solvent (DES) coupled with high performance liquid chromatography- ultraviolet spectroscopy (HPLC-UV). Water samples for BPA and PAEs extraction were from various rivers and lakes in Selangor. The solvent used in the DES was a mixture of decanoic acid and tetrabutylammonium iodide. The extraction parameters that have been studied are molar ratio i.e., 1:2, 1:3 and 1:4, extraction time i.e., 10, 15 and 20 min, extraction temperature i.e., 50, 60 and 70 ºC and solvent volume i.e., 3, 6 and 9 mL. The optimum molar ratio of solvent and extraction time were 1:2 and 20 min, respectively. The best extraction temperature and volume of solvent with the highest recovery rate were 70 ºC and 3 mL. Sungai Kuang shows the highest bisphenol-A concentration of 23.9613 µg/L while Sungai Nada has the highest benzyl-butyl phthalates concentration of 73.6834 µg/L. Sungai Damansara shows the highest dibutyl phthalates concentration of 7.3163 µg/L. In conclusion, data obtained in this research will contribute a new knowledge in the Sustainable Development Goals 6, which is clean water and sanitation because the world is progressing to increase access to clean drinking water and sanitation. There are also some other endocrine disrupting chemicals (EDC) such as disinfection byproducts and pesticides which is more suitable to be extracted from water samples using solid phase microextraction due to low contamination in water. It is very important to research, detect and extract the bisphenol and phthalates from water sources as these pollutants might cause health issues and environmental pollutions which cannot be resolved in future due to its smaller size and its existence in large quantity.","PeriodicalId":21366,"journal":{"name":"Sains Malaysiana","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48819560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
