Screening and Characterisation of Antibacterial Actinomycetes Isolated From Earthworm
Abstract: The actinomycetes are considered to be the most potent source for the production of secondary metabolites, antibiotics and other bioactive compounds. The present study dealt with the isolation of the actinomycetes from the earthworm, Eisenia fetida. The actinomycetes were identified using slide culture technique and various biochemical tests. The isolates (S1 and S2) showed activity against Gram positive and Gram negative bacteria in primary screening by perpendicular streak method. In …

Seroprevalence with Clinical Manifestations and Laboratory Profiles of Scrub Typhus Infection in Patients Attending to a Tertiary Care Hospital in Kota, South-East Rajasthan, India
Abstract: Background: Scrub typhus, a zoonotic rickettsial illness, is caused by Orientia tsutsugamushi, an obligate intracellular Gram-negative bacterium. It is transmitted by the bite of larval (chiggers) trombiculid mites.Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is being described as a re-emerging infectious disease in India. Overall mortality varies from 7 to 30%. Objectives: The objective of the present study was to …

To Compare the Anti-Bacterial Activity of Uva Ursi 200 And Cantharis Vesicatoria 200 In Isolated E-Coli of Different Urine Samples by Kirby Bauer Disc Diffusion Method
Abstract: Background: The most common bacterial infections are Urinary Tract Infections (UTI), primarily caused by Escherichia coli (E. coli), a gram negative bacterium responsible for 80-90% of community-acquired UTIs. The rise of antibiotic-resistant E. coli strains has increased the demand for Homoeopathic remedies. This study explores the antibacterial efficacy of Uva ursi 200 and Cantharis vesicatoria 200, using Kirby-Bauer Disc Diffusion Method, by comparing the Zone of Inhibition (ZOI) of those …

Biological Synthesis of Silver Nanoparticles Using Hibiscus Sabdariffa Leaf Extract and It’s Antibacterial Sensitivity Assay
Abstract: In this study, AgNO3 was effectively used to synthesize silver nanoparticles. Hibiscus sabdariffa leaf extract was used to promptly and easily synthesize silver nanoparticles. An UV-Visible spectrophotometer showed absorbance peak in range of 300-600 nm. The procedure was found to be easy to follow, quick, least step and safe for the environment. It is non-toxic, and a viable substitute for traditional physical or chemical procedures. At room temperature, silver ions …

Synthesis of new heterocyclic compounds containing nitrogen, sulphur and study their biological activity
Abstract: Several substituted pyridines with brominated coumarin and with other substituents were achieved by condensing brominated coumarin IV with 4-methoxybenzaldehyde in basic solution forming α,β-unsaturated ketone II. Hantzsch reaction of this ketone with β-ketoester to provide precursor substituted pyridines. The Hantzsch reaction product was subjected to different reactions. The other targeted heterocyclic compound was obtained by reaction of α,β-unsaturated ketone II with hydrazine carbothioamide to give substituted pyrazole with brominated coumarin, …

Improving Photocatalytic and Antibacterial Properties of Zein/Polyvinyl Alcohol Polymer Composite Film by Dispersing TiO2 Nano Particles
Abstract: Zein/polyvinyl alcohol/nano-TiO2 composite film was effectively blended using a solution casting method. Mechanical, photocatalytic, and antibacterial properties of the composite film were evaluated. The breaking elongation of the composite film increased up to the maximum loading of 0.4% of nano-TiO2. The humidity and moisture content relationship was estimated with standard modified models of Halsey, Oswin, Chung Pfost, and Henderson. It was found that the Halsey model was the most suitable …

Neonatal Sepsis: A Study on Isolated Pathogens and Their Susceptibility Pattern at Tertiary Care Hospital in Rural Setting
Abstract: Neonatal sepsis is one of the most important causes of infant mortality and morbidity. In spite of availability of broad spectrum antibiotics, treating sepsis has become a challenge due to emergence of resistant strains from time to time. The present study is aimed at to isolate the organisms causing sepsis in neonates and their antibiotic susceptibility patterns. From April 2013 to June 2014, 167 blood samples were collected from clinically …

Aspect-Based Sentiment Analysis Using a Hybrid Approach with Dependency Parsing
Abstract: The rapid expansion of digital communication has resulted in an unprecedented volume of consumer-generated textual data across online reviews, social media platforms, forums, and e-commerce websites. Extracting meaningful insights from this data is increasingly important for organizations seeking to understand customer opinions, preferences, and behavioral trends. Despite significant advances in sentiment analysis, many existing approaches primarily focus on surface-level features and often overlook deeper syntactic and semantic relationships within text. …

In Silico Investigation of 2,3-Dihydrobenzofuranfrom Centella asiatica: A Possible Pioneer in the Management of Tetanus
Abstract: Objective: Tetanus toxin (TeNT) is a neuroprotein toxin, the most toxic known. They have three functional domains and are structurally similar. They possess an N-terminal catalytic section (light chain), an internal domain for heavy-chain translocation (HN domain), and a C-terminal receptor binding domain for the heavy chain (Hc domain or RBD). Tetanus, an acute nerve-affecting disease, is provoked by a toxin-producing bacterium called Clostridium tetani. This bacterium is environmental, Gram-positive, …
