Background And Objectives: Plants contain a wide variety of bioactive compounds, which have attracted the interest of researchers in finding novel sources of natural medicine. In the following paper, we aim to evaluate the antibacterial potential of extract fractions associated with Parkia speciosa pods and beans against human pathogenic bacteria.

Methods: Antimicrobial activity was determined with disc diffusion and broth microdilution assays against eight skin colonising microorganisms including Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia followed by further fractionation of the pods ethyl acetate fraction by column chromatography along with preparative thin-layer chromatography.

Wound is defined as the damage to biological tissues including skin, mucous membranes and organ tissues. The acute wound heals in less than 4 weeks without complications, while a chronic wound takes longer than 6 weeks to heal. Wound healing occurs in 4 phases, namely, coagulation, inflammatory, proliferative and remodeling phases.

Plant pathogens with their abundance are harmful and cause huge damage to different agricultural crops and economy of a country as well as lead towards the shortage of food for humans. For their management, the utilization of entomopathogenic fungi is an eco-friendly technique, sustainable to the environment, safe for humans and has promising effect over chemical-based pesticides. This process requires a biochemical mechanism, including the production of enzymes, toxins, and other metabolites that facilitate host infection and invasion.

Introduction: In the recent year's literature, attachment insecurity is described as a vulnerability factor among patients with chronic pain, associated with poor pain coping, anxiety, depression, catastrophizing, greater pain intensity, and disability. Self-compassion, on the other hand, is described as a protective factor, associated with lower levels of negative affect, catastrophizing, depression, and anxiety in patients with chronic pain.

Methods: In this study, we aim to explore the association between attachment, self-compassion quality, and coping strategies, in patients with chronic pain.

The biosynthesis of nanoparticles using the green route is an effective strategy in nanotechnology that provides a cost-effective and environmentally friendly alternative to physical and chemical methods. This study aims to prepare an aqueous extract of (-based silver nanoparticles (AgNPs) through the green route and test their antibacterial activity. The biosynthesized silver nanoparticles were characterised by colour change, UV spectrometric analysis, FTIR, and particle shape and size morphology by SEM and TEM images.

A series of novel macroacyclic Schiff base ligands and their Cu (II) complexes were synthesised via reacting dicarbonyls of varying chain lengths with -methyl dithiocarbazate (SMDTC) and -benzyl dithiocarbazate (SBDTC) followed by coordination with Cu (II) ions. X-ray crystal structures were obtained for compound , an SBDTC-diacetyl analogue, and , an SMDTC-hexanedione Cu (II) complex. Anticancer evaluation of the compounds showed that , an SMDTC-glyoxal complex, demonstrated the highest cytotoxic activity against MCF-7 and MDA-MB-231 breast cancer cells with IC values of 1.

The WHO declared coronavirus disease 2019 (COVID-19) a pandemic in March 2020, which was caused by novel coronavirus severe acute respiratory coronavirus 2 (SARS-CoV-2). SARS-CoV-2 made its first entry into the world in November 2019, and the first case was detected in Wuhan, China. Mutations in the SARS-CoV-2 genome distressed life in almost every discipline by the extended production of novel viral variants.

Article Synopsis
  • Infections caused by the protozoan Giardia can be asymptomatic or lead to symptoms like diarrhea (non-bloody), abdominal cramps, bloating, flatulence, and weight loss, making it a significant health concern, especially for children under five.
  • Giardia is the third leading cause of diarrhea and death in young children, following rotavirus and other infections, and is primarily treated with antimicrobial drugs like 5-nitroimidazole.
  • The review suggests that individuals with weak immune systems are more susceptible to Giardia infections, but those in endemic areas may develop some resistance, indicating that future vaccination efforts, aided by advancements in nanoparticle technology and antigen research, could effectively mitigate this parasitic disease.
