Mnay plant species of this genus have ethnomedicinal properties, which are used to deal various health complications, including dysentery, severe fever, cough, diabetes, hypertension, hyperlipidemia, constipation, and inflammation. This review sought to summarize details on the ethnomedicinal uses, phytochemical composition, safety aspects, and toxicology of Wendlandia species. Additionally, it covered the nomenclature, distribution, taxonomy, and botanical characteristics of this genus. Several electronic databases were used to retrieve the information, including Google Scholar, PubMed, Web of Science, Scopus, Science Direct, and Springer Link. The Plant List (www.theplantlist.org) was used for taxonomical authentications. SciFinder and PubChem were utilized for the verification of chemical structures and IUPAC (International Union of Pure and Applied Chemistry) name of the compounds. Numerous examinations of chemical constituents of the Wendlandia genus have identified approximately 60 essential plant compounds, such as iridoid glycosides, flavonoids, flavonoid glycosides, carotenoids, and triterpenes. Various research studies have showcased the therapeutic potential of Wendlandia species, highlighting their abilities in treating diabetes, combating oxidation, reducing inflammation, fighting microbes, lowering blood pressure, and potentially hindering cancer growth. The significance of Wendlandia in traditional medicine systems and its role as a valuable origin of impactful natural compounds are evident. This review provided scientific basis for future endeavors, including chemical investigations into already studied species and other less studied species of Wendlandia for finding future lead compounds.\u0000J.

On the other hand, more than 80% liquid yield was achieved using silica-alumina catalysts from waste HDPE and LDPE. The highest liquid yield was obtained from LDPE (87.69%) than HDPE (83.25%) at a catalyst-to-plastic ratio of 1:25. The 1H NMR shows that the liquid product does not contain any aromatic compound. The GC-MS, 1H NMR, and FTIR confirmed that the liquid contains linear and branched alkanes and alkenes.\u0000J. Bangladesh Acad.

The results revealed that plant height, leaf number, chlorophyll content, photosynthesis, stomatal conductance, transpiration rate, relative water content and water uptake capacity of soybean drastically reduced due to drought. However, root: shoot ratio increased under drought condition. Across the genotypes, the root : shoot ratio ranged from 0.20 to 0.47 in control, while 0.22 to 59 in drought condition. Genotypes BD2336, AGS383 and G00006 produced higher number of pods and seeds, whereas minimum yield reduction was recorded in AGS383 under drought. Based on drought tolerance index, AGS383 ranked 1st, while BD2336 and PK472 ranked 2nd and 3rd position, respectively. High grain yielding ability of AGS383 suggested that it could be cultivated in drought prone environment.\u0000J. Bangladesh Acad.

Temperature, pH, conductivity, turbidity, and total suspended solids were assessed before and after adding the coagulants. Results obtained on the percentage reduction in interface height show lesser percentages (0.47, 0.76, 1.14, and 0.19%) when varying concentrations (50, 60, 70, and 80 mg/L) of MO seed extract were employed compared to the superior reduction percentages (87.07, 90.09, 95.27 and 94.57%.) when the same varying concentrations of Alum solution were added. Nonetheless, the percentage reduction in interface heights of the coagulants are significantly (p<0.05) different from each other.\u0000J. Bangladesh Acad.

The present research was conducted to appraise the uterine organism in healthy fertile cows (HFC) and repeat breeder cows (RBC) and to establish a relationship with previous disease or disease conditions. A total of 43 uterine samples were collected from 10 healthy fertile and 33 RB cows for bacteriological study. Among RBC, 39.4% harbored bacterial isolates of E. coli (30.3%), Staphylococcus aureus (27.3%), Staphylococcus epidermidis (15.2%), and Bacillus spp. (18.2%). Total Viable Count (TVC) of RBC with isolates was higher (1.81 x 1010CFU/mL) than in normal fertile cows (1.3x1010 CFU/mL). No bacterial isolates were recovered from 60.6% RBCs and 80.0% healthy fertile cows. A single, mixed infection of two, three and four bacterial species was observed in the uterine discharge of 12.1%, 9.1%, 12.1% and 6.1% RBC, respectively. From animal demographic data of RBC, the sub-clinical mastitis, acute mastitis, endometritis, dystocia, retention of placenta, and abortion were 42.4%, 39.4%, 39.4%, 12.1%, 9.1%, and 6.1%, respectively. In contrast, the presence of dystocia, endometritis, subclinical mastitis, retention of placenta and abortion was recorded in 50%, 30%, 30.8%, 23.1%, and 15.4% of healthy cows, respectively.

Shoily, Zinia Haidar, A. Sajib","doi":"10.3329/jbas.v47i1.65144","DOIUrl":"https://doi.org/10.3329/jbas.v47i1.65144","url":null,"abstract":"The severity of the coronavirus disease 2019 (COVID-19) is linked to pro-inflammatory cytokine levels. There are still many unanswered questions regarding COVID-19 pathogenesis and prognosis. Significantly increased levels of pro-inflammatory cytokines characterize severe COVID-19 compared to those with a mild-to-moderate form of the disease. In this study, we used in silico tools to explore the variant allele frequency distributions of three important pro-inflammatory cytokine genes: interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNFA), as well as their linkage disequilibrium (LD) patterns in worldwide populations. These cytokines were chosen for their pro-inflammatory properties, importance in determining COVID-19 outcomes, and potential as disease treatment targets. Twenty-two of the variants correlate with altered cytokine expression levels, which may also influence the expression of several other mediators of immune responses. These variants also appear to be associated with several COVID-19 comorbidities, such as diabetes, asthma, obesity, and heart conditions. At least one variant (rs1800795 in IL6) is likely associated with an altered response to TNFA inhibitors, which are considered COVID-19 treatment options. The European super-population has high variant allele frequencies (VAF ≥ 0.2) at thirteen of these variant loci. High genetic heterogeneity at these loci is present in the admixed American populations, whereas the East Asian populations appear genetically more homogeneous. Interethnic differences are more pronounced at the IL6 SNP loci, which may cause variances in the expression level of a long non-coding RNA gene, IL6-AS1. Stronger and more extensive LD (R2 ≥ 0.8) exists among the IL6 and IL8 variants in the European super-population and among the TNFA variants in the East and South Asian populations. In general, the European super-population has higher frequencies of haplotypes with multiple variant alleles. Such interethnic differences may shed more light on the disparities in COVID-19 severities and the responses to treatments across ethnic groups.\u0000J. Bangladesh Acad.

Four individuals of this species were collected from Cox's Bazar (21.77 N 91.62 E) on 5 October 2018 as bycatch. The species was taxonomically identified through the traditional morphometric method which was further validated by a molecular approach based on partial cytochrome c oxidase subunit I (COI) sequences (DNA barcodes). The body length is three times of the head length and 4.1 times of the body height. Head length is 2.5 times larger than the snout length and 3.2 times of the eye diameter. The number of scales on the lateral line is 60. A smaller blue spot is present on the inner side of the pectoral fin. The average K2P distances of the COI sequence within species were 0.53. In the Maximum likelihood (ML) tree, the sequences clustered together under a single clade. Morphometric, meristic and molecular data thus confirmed the species as L. longimana. J. Bangladesh Acad.
