Unlabelled: Antimicrobial resistance (AMR) poses a foremost threat to global health, necessitating innovative strategies for discovering antimicrobial agents. This review explores the role and recent advances of techniques in identifying novel antimicrobial agents and combating AMR giving few briefings of recent case studies of AMR. techniques, such as homology modeling, virtual screening, molecular docking, pharmacophore modeling, molecular dynamics simulation, density functional theory, integrated machine learning, and artificial intelligence, are systematically reviewed for their utility in discovering antimicrobial agents.

Biodegradable and sustainable food preservation materials have gained immense global importance to mitigate plastic pollution and environmental impact. Biopolymers like cellulose offer significant advantages for food preservation, including biodegradability and the ability to extend shelf life. Therefore, the present study aims to prepare gallic acid (GA) and zinc oxide nanoparticles (ZnO NPs) incorporated methylcellulose (MC) composite films by employing a solvent casting technique.

Methylcellulose, a prominent polysaccharide prevalent in the food sector, was considered to fabricate the active films with glutaraldehyde as a crosslinker and Noni (Morinda citrifolia) Leaf Extract (NLE) as an active agent. FTIR analysis confirms the intermolecular -OH bonding, and SEM micrograms demonstrate methylcellulose active films' homogeneous, dense morphologic appearance. Due to the crosslinking effect of glutaraldehyde and noni leaf extract, tensile strength (41.

Background Treatment options for traumatic optic neuropathy (TON) are limited and the role of steroids in the treatment of TON is still controversial. Hence this study was planned to highlight the role of steroids in the treatment of TON. Purpose The study aims to highlight the epidemiological and clinical characteristics, as well as the role of steroids, in TON cases seen during a three-year period at a tertiary care center in India.

Solar photovoltaic (PV) energy is one of the most widely used renewable energy options around the world. However, its electrical efficiency drops with increasing PV module temperature, it is therefore necessary to find appropriate ways to improve the performance of the module under high temperature conditions. In this study we evaluated the impact of simultaneous dual surface cooling on the PV module's output performance experimentally.

Cerebral malaria (CM) is a fatal neurological complication of Plasmodium falciparum infection that affects children (below five years old) in sub-Saharan Africa and adults in South-East Asia each year having the fatality rate of 10-25%. The survivors of CM also have high risk of long term neurological or cognitive deficits. The objective of the present investigation was to develop optimised nanostructured lipid carriers (NLCs) of artemether (ARM) for enhanced anti-malarial efficacy of ARM.

Background: To identify the sex of the deceased individual from dental hard tissue such as enamel and dentine.

Objective: To isolate the DNA from dental hard tissue (enamel and dentin) from teeth extracted for prophylactic purpose, to assess the quality and purity of DNA and to identify the sex using polymerized chain reactor (PCR).

Materials And Methods: DNA was extracted following phenol/chloroform (organic) extraction from 20 male and 20 female teeth.

Purpose: Ocular manifestations in snake-bite injuries are quite rare. However, the unusual presentations, diagnosis and their management can pose challenges when they present to the ophthalmologist. Early detection of these treatable conditions can prevent visual loss in these patients who are systemically unstable and are unaware of their ocular condition.

Our understanding of the association between synovial sarcoma and peripheral neurolymphomatosis is limited to a few case reports in literature. Delay in diagnosis or misdiagnosis is possible due to its insidious onset and varied presentation compounded by non-specific imaging findings. Needle biopsy also may not be confirmatory especially, in cases of biphasic sarcoma as in our case, and it may be necessary to proceed to open biopsy.

Context: Serum Alkaline phosphatase (ALP) & phosphate are considered to be indicators of vascular calcification. Link between bone metabolism, vascular calcification, cardiovascular events have been well studied in chronic kidney disease and ischemic heart disease.

Aims: To determine that increased serum phosphate and alkaline phosphatase are predictors of mortality rates and recurrent vascular events in stroke.

Background: In the era of highly active antiretroviral therapy, sensory neuropathies have increased in prevalence. We have documented the frequency and profile of the two most common forms of sensory neuropathies associated with Human Immunodeficiency Virus (HIV) infection and looked into clinicoelectrophysiological correlates to differentiate the two entities.

Methods: The study population comprised of all consecutive patients detected to be HIV positive and attending the Neurology outpatient department (from March 2011 to March 2012) who were aged ≥ 18 years and were able to give informed consent.

Opercular syndrome is a well known but neglected entity and is quite common, but it is difficult for non-neurologists to diagnose this entity because of lack of awareness. Inability to speak and swallow with dissociation of automatic voluntary movements in the affected muscles are the essential features of this syndrome. The aetiology in most of the reported cases is vascular (thrombosis or embolism) involving branches of middle cerebral artery supplying the opercular area.

Background: Epilepsy is a neurological condition affecting men and women of all age groups and is associated with psychiatric comorbid conditions. There is a paucity of published data available regarding psychiatric comorbid conditions in patients with epilepsy (PWEs) from developing countries.

Methods: We compared the psychiatric comorbid conditions in 80 PWEs, 80 patients with asthma (asthma control (AC) subjects), and 80 healthy controls (normal control (NC) subjects) using the Mini International Neuropsychiatric Interview (MINI) for the diagnosis of Axis I psychiatric disorders.

The design, synthesis and evaluation of 3-methylene-substituted indolinones as falcipain inhibitors and antiplasmodial agents are described. These compounds react readily with thiols via an addition-elimination mechanism, indicating their potential as cysteine protease inhibitors. Several indolinones containing a Leu-i-amyl recognition moiety were found to be moderate inhibitors of the Plasmodium falciparum cysteine protease falcipain-2, but not of the related protease falcipain-3, and displayed antiplasmodial activity against the chloroquine-resistant P.
