As a result, this study assesses the iodine content of ten selected vegetables—water leaf, okra, green, tomatoes, lettuce, “okazi”, “ugu”, cabbage, “uha” leaf, and garden egg leaf. The result revealed varying iodine concentrations among these vegetables: 159.93±2.25 μg/kg for water leaf, 151.27±1.61 μg/kg for okra, and 160.43±4.37 μg/kg for green. Tomatoes exhibited 110.10±2.76 μg/kg, while lettuce had 181.27±1.76 μg/kg. “Okazi”, “ugu”, cabbage, “uha” leaf, and garden egg leaf showed iodine levels of 155.10±3.50 μg/kg, 153.43±2.47 μg/kg, 96.10±2.00 μg/kg, and 127.77±3.01 μg/kg, respectively. The evaluation for goitrogens demonstrated sufficient presence in these vegetables, with notable exceptions such as zinc, which was found in lower concentrations in “ugu”, lettuce, “okazi”, and cabbage, and was absent in “uha” leaf, garden egg leaf, green, water leaf, and okra.  Based on these results, it was concluded that Owerri's vegetables exhibit relatively high iodine content within recommended dietary allowances. Consequently, ongoing vigilance is advised for the salt iodization program to prevent excess iodine intake, particularly among high-risk populations.","PeriodicalId":504014,"journal":{"name":"Asian Journal of Biochemistry, Genetics and Molecular Biology","volume":"21 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141104440","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}

It used in folklore medicine in the management of pain, anti-microbial and insecticide. An investigation was carried out to evaluate the various taxonomic, pharmacognostic and phytochemical standards to ensure the identity, purity, safety and efficacy of the medicinal plant, S. speciosa. Various observations were recorded which included microscopy, micromeritics, fluorescence, chemomicroscopy, soluble extractive values, moisture contents and phytochemical analysis. The results indicated that the epidermal shapes were both polygonal on the adaxial and abaxial surfaces. Stomatal distribution was amphistomatic with anisocytic and diacytic stomata on the adaxial and abaxial surface, respectively. Stomatal index was 21.47% on the adaxial surface and 15.43% on the abaxial surface. Micromeritics results for the leaf powder were bulk volume of 25.33± 0.408, tapped volume of 19.00± 0.00, bulk density of 0.40± 0.006, tapped density of 0.53± 0.021, Hausner’s ratio of 1.34± 0.037, Carr’s index of 25.00± 2.550 and angle of repose of 43.07°. The micromeritics indicated a passable flow. The chemo microscopy indicated presence of lignin, mucilage and starch.

A group (n = 5) was kept as healthy control while the others were pre-treated with 140 mg/kg of alloxan monohydrate in distilled water. The alloxan-induced diabetic mice were randomly divided into four groups: diabetic model control group, 60 mg/kg chloroquine, 120 mg/kg chloroquine, and 10 mg/kg glibenclamide treatment groups respectively. Treatment was done once daily for seven days and the blood glucose level was investigated acutely and then daily throughout the experimental period. A molecular docking study was also conducted to evaluate the interaction of chloroquine with PTEN using PYRX software, while an automated COBAS C 311 machine was used to analyze the lipid profile after the treatment period. \u0000Results: Oral administration of chloroquine gradually and significantly lowered the raised blood glucose level in a time- and dose-dependent manner. A repeated study with 120 mg/kg of chloroquine revealed a decline in blood sugar from 221.5 ± 3.6 on day 1 to 85.5 ± 2.4 on day 7 in comparison to glibenclamide, whose sugar level was reduced to 75.5 ± 3.7 at the end of day 7. The docking study revealed a non-competitive inhibition with an inhibition score of -6.1 in comparison to metformin, which had a score of -4.4, and glibenclamide, which had a score of -9.0. This interaction resulted in a conformational change of the receptor, hence, enhancing glucose uptake and reducing the raised hyperglycemia. Treatment with chloroquine was also observed to reduce the total cholesterol and triglyceride levels from 162 in the model group to 144 and 141 to 116 mmol/L, respectively. The levels of low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein (VLDL) following treatment with chloroquine were not statistically different from the non-diabetic healthy mice. These values were very similar to those obtained with glibenclamide-treated diabetic mice.\u0000Conclusion: From the results, chloroquine possesses potent antidiabetic properties and can improve dyslipidemia imposed by hyperglycemia probably owing to its inhibition of PTEN, a negative regulator of insulin resistance.","PeriodicalId":504014,"journal":{"name":"Asian Journal of Biochemistry, Genetics and Molecular Biology","volume":"6 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141004464","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}

The strain was obtained from soil enriched with paclobutrazol, and its degradation ability was assessed using gas chromatography (GC). \u0000Methods: A single strain was isolated from the soil solution of Ophiopogon japonicus, a plant exposed to excessive paclobutrazol spraying. Initial isolation utilized dilution and plating methods, followed by separation and purification through the streak plate technique. BLAST analysis revealed the strain's highest similarity to Deinococcus arenae SA1, with 100% homology after removing excess sequences. Subsequently, the degradation efficiency of this bacterium on paclobutrazol was evaluated by gas chromatography. \u0000Results: Quantification using the external standard method yielded a standard curve equation of y=0.0977x-0.412, with a correlation coefficient (R²) of 0.99842. Testing at different time showed that the Deinococcus arenae achieved a degradation rate of 2.49% after three days of degrading paclobutrazol. After five days, the degradation rate increased to 17.58%, reaching 38.66% after seven days, 42.20% after nine days, and 43.87% after eleven days. \u0000Conclusion: The Deinococcus arenae strain exhibited a significant degradation effect on paclobutrazol.

However, cases of toxicological effects have been reported. The present study aims to assess the safety level of herbal medicines by monitoring the organochlorine pesticide (OCP) residues content. This study assessed the presence of seventeen organochlorine pesticide residues in twenty-seven (27) herbal medicine samples (14 liquid and 13 solid) collected from seven Local Government Area of Lagos state, Nigeria. The residues were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) with solid phase extraction. Results showed the presence of banned OCP residues in all the selected samples at concentrations greater than the Maximum Residue limit, MRL. The Estimated Daily Intake, EDI measures the level of exposure to the pesticide residues for all the samples were found to be lower than the Acceptable Daily Intake, ADI. Health Risk Index (HRI) of all the selected samples was generally lesser than one (1) which indicates that long term exposure may not be of immediate concern to the consumers. The solid herbal medicines were found to have higher mean concentration, EDI and HRI when compared to the liquid herbal samples, suggesting that processing and preparation techniques for solid herbal medicines should be improved. The presence of the banned OCP residues in herbal medicine is, however, of public health interest and should be regularly monitored.","PeriodicalId":504014,"journal":{"name":"Asian Journal of Biochemistry, Genetics and Molecular Biology","volume":"11 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141048080","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}

Escherichia coli was isolated from the samples using standard microbiological methods. Antibiotic susceptibility testing was evaluated as described by the Clinical and Laboratory Standards Institute (CLSI). The detection of ESBL production in E. coli isolates was carried out using double disc synergy test.  In addition, molecular detection of ESBL genes was carried out using Polymerase Chain Reaction (PCR) method.\u0000Results: The prevalence of E. coli was 17.5% (21/120), out of which two (2) of the positive isolates (9.5%) were male, and 19 (90.5%) female. Antibiotic resistances in the isolates in decreasing order were as follows: sulphamethoxazole / trimethoprim (SXT: 81.0%), amoxicillin/clavulanic acid (AMC: 61.9%), ofloxacin (OFX: 66.7%), cefotaxime (CTX: 53.4%), gentamicin (CN: 42.9%), ceftriaxone (CRO: 33.3%), imipenem (IPM: 33.3%), meropenem (MOR: 42.4%), nitrofurantoin (NET: 20.3%) and ciprofloxacin (CIP: 23.8%). The commonest antibiotic resistant resistance phenotype was CIP-OFX-SXT (23.8%). Multiple antibiotic resistance (MAR) was observed in 90.5% (19/21) of the isolates, with the common MAR index being 0.3 (23.8%). Six of the twenty one beta-lactam resistant isolates (28.5%) were confirmed ESBL producers. The 6 ESBL positive isolates carried bla genes as follows: blaTEM (1/6, 16.7%) and blaCTX-M (1/6, 16.7%). blaSHV only was not found in any of the isolates.\u0000Conclusion: The E. coli isolates from urine of patients in General Hospital, Karshi, Abuja, Nigeria was less resistant to ciprofloxacin, nitrofurantoin, meropenem and imipenem.
