ABSTRACT
Antimicrobial drug resistance is gradually increasing throughout the globe, and there is practically no newer antimicrobial agent coming soon. Plant secondary metabolites are well known for their various biological activities, and there are few studies targeting mangrove plants. Thus, in this study, we aim to assess the effectiveness of the ethanolic extract of the flowers of Avicennia marina, a commonly found mangrove species in coastal regions, against multi-drug resistant (MDR) microorganisms. The study focused on evaluating the extract's antibacterial activity against Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), Escherichia coli (MDR), Klebsiella sp. (MDR), Acinetobacter sp. (MDR), Pseudomonas sp. (MDR). The results of the study demonstrated that the flower extracts of Avicennia marina exhibited noteworthy antimicrobial properties against all the tested MDR microorganisms. The plant contains several bioactive compounds, such as flavonoids, tannins, and alkaloids, which are believed to contribute to the observed antimicrobial effects. These findings indicate that Avicennia marina flowers could serve as a valuable natural source for developing antimicrobial agents that could combat drug-resistant bacterial infections. However, future studies should focus on evaluating the efficacy and safety of this extract in live organisms (in vivo) to determine its potential as a new drug for treating resistant infections.

ABSTRACT
The need to screen efficient, safe, affordable, and readily available antimicrobial agents from various medicinal plants, for their potential antimicrobial activity has become critical in light of the rapid development of microbial resistance against chemotherapeutic drugs (mainly antibiotics). Despite notable advances in the biological and phytochemical evaluation in recent years, comprehensive reviews of Holarrhena pubescens are limited. The main objective of this study is to evaluate the antimicrobial activities of this plant extract. One significant use of plant extracts can be in treating bacterial infections and develop potential antibacterial agents against multi drug resistant (MDR) and susceptible bacteria. If antimicrobial activities are present, these extracts will provide useful information for discovering new compounds with better activity and more effectiveness against resistant and susceptible bacteria responsible for infections than currently available. The ethanolic extract of leaves of Holarrhena pubescens was prepared and tested against multidrug resistant (MDR) and American type culture collection strains of bacteria. We have obtained two types of results in this experiment. The extract showed antimicrobial properties against Staphylococcus aureus (ATCC 23235), Escherichia coli (MDR) and Acinetobacter (MDR), while, it showed no antimicrobial activities along with some growth promoting role against Escherichia coli (ATCC 25922), and Klebsialla pneumoniae (MDR), which may be due to chemicals other than secondary metabolites.

ABSTRACT
This study aimed to estimate important genetic parameters such as genotypic coefficient of variance (GCV), phenotypic coefficient of variance (PCV), heritability (h2) and expected genetic advance (EGA) for newly developed soybean (Glycine max) genotypes based on yield and yield-related traits. Fifteen genotypes collected from the University of Agriculture Makurdi were studied. The results showed that there was sufficient variability in the material for all the studied traits, with high heritability estimates coupled with high expected genetic advance observed for number of leaves (4, 6 and 8) weeks, plant height (4, 6 and 8) weeks, leave length (6 and 8) weeks and yield per plant.

ABSTRACT
Bakreswar hot spring is a naturally occurring hot spring located at Birbhum district in West Bengal, India. The surface temperatures of the hot springs varies between 35°C to 66°C. The water of hot spring is alkaline with pH 9 and has curative properties. Pseudomonas aeruginosa is an important pathogen causing hospital acquired infections and in this study we used multi-drug resistance (MDR) isolate. The motive of the study is to compare the IL-10 and IFN-γ gene expression changes in Gallus gallus domesticus embryo infected with Pseudomonas aeruginosa by using the Bakreswar hot spring water.The curative properties of the hot spring water collected from Agnikund (65°C) was studied on 14thdays old chick eggs infected with Pseudomonas aeruginosa. After harvesting and allantoic fluid collection, RNA extraction was done and cDNA synthesis and RT-PCR were performed. After infection of the chick embryo with MDR Pseudomonas aeruginosa, both IL-10 and IFN-Ƴ gene expressions were increased, but in the curative sets those were challenged with Bakreswar hot spring water IL-10 and IFN- γ both gene expressions were decreased. From this study we may conclude that hot spring water of Bakreswar has antimicrobial activity against Pseudomonas aeruginosa due to which it decreses the cytokine gene expressions.

ABSTRACT
A study was conducted on sixty-four (64) groundnut genotypes at Pawe northwestern part of Ethiopia. And the analysis of variance revealed the existence of significant variation among the tested groundnut genotypes. Cluster analysis showed the existence of five (5) divergent groups and the maximum inter-cluster distance was observed between cluster (II) and cluster (V) D2=1419.77 and the shortest inter-cluster squared distance was found between cluster (I) and Cluster (III) D2=247.23. The first four principal components for (PCs) accounted for 70.03% of the total variation. Overall, the results of the current study depicted the presence of sufficient genetic diversity existed among tested groundnut genotypes for further use in breeding programs. However, a one-season experiment will not realize variability because quantitative traits are polygenic and highly influenced by the environment. So, further experiments must be conducted over location and seasons.

ABSTRACT
Background: Male infertility affects 7% of males worldwide (i.e. 30 million of men). The diagnosis of the condition is based firstly on the semen analysis which can show various types of abnormalities. In Congo, data on male infertility are poor. This study aimed to determine the prevalence of male infertility in Brazzaville and to provide the profile of the semen parameters from a cohort of infertile men living at Brazzaville. Material and Methods: We studied semens of three hundred and forty-four (344) congolese men affected by infertility. The work was based on medical data to research medical history and the semen to performed the spermogram and spermocytogram in way to precise the sperm parameters, Results: The prevalence of male infertility found was 9% and the average age was 39 years old. Medical history highligts mostly the notion of chronic infection, varicoceles and surgery of the genital tract. The most identified sperm abnormalities were moderate asthenozoospermia followed by severe oligoasthenozoospermia and azoospermia. Conclusion: The prevalence shows that male infertility is not rare in Brazzaville. As the condition seemed to be related to the infectious, tumoral and professional causes, a complete investigation (based on sperm analysis, biochemical markers and genetic tests) is needed to clarify the etiologies.
