Deciphering the Vulnerability of Pollen to Heat Stress for Securing Crop Yields in a Warming Climate.

Climate change is leading to more frequent and severe extreme temperature events, negatively impacting agricultural productivity and threatening global food security. Plant reproduction, the process fundamental to crop yield, is highly susceptible to heatwaves, which disrupt pollen development and ultimately affect seed-set and crop yields. Recent research has increasingly focused on understanding how pollen grains from various crops react to heat stress at the molecular and cellular levels.

Pesticide pollution: toxicity, sources and advanced remediation approaches.

The Food and Agricultural Organization of the United Nations (FAO) estimates that food production must rise by 70% to meet the demands of an additional 2.3 billion people by 2050. This forecast underscores the persistent reliance on pesticides, making it essential to assess their toxicity and develop effective remediation strategies.

An ecofriendly approach to bioremediate nickel oxide nanoparticles using a macrofungus, Pleurotus fossulatus.

Nowadays, nickel oxide nanoparticles are in great demands owing to their use in many sectors.

Therefore, an effective and efficient method is required to remove these nanoparticles from contaminated water.

A Foreign Body Aspiration Leading to Pneumothorax: A Case of Airway Emergency.

Foreign body (FB) aspiration is a matter that should not be taken lightly. The presence of a foreign object might lead to hazardous complications, particularly in the pediatric population. These complications depend on the type and location of the aspirated object as the tracheobronchial tree has a very small diameter, and foreign bodies become stuck in the upper airways of children, causing stridor and sudden difficulty in breathing.

A Case of an Uncommon Lower Lip Swelling.

A woman in her fifty-seventh year appeared with a painless swelling on her left lower lip that had been present for three years. The size of the swelling was noticeably increasing in size over time. On examination, there was a lump that was firm, non-tender, and measured 2 cm x 1 cm above the lower lip.

Findings from a Malaysian multicentre study on oropharyngeal squamous cell carcinoma.

Background: In addition to the conventional aetiologic agents of oropharyngeal squamous cell carcinoma (OPSCC) such as tobacco usage, alcohol consumption and betel quid usage, it has been established that a proportion of OPSCC are driven by persistent oncogenic human papillomavirus (HPV) infections. Currently, there is a lack of data on the burden of HPV- associated OPSCC in Asian countries including Malaysia.

Methods: A cross-sectional multicentre study with tissue analysis of Malaysian patients diagnosed with primary OPSCC within a five-year period, from 2015 to 2019 between 01/01/2015 to 31/12/2019 was undertaken.

Computational Approaches to Designing Antiviral Drugs against COVID-19: A Comprehensive Review.

The global impact of the COVID-19 pandemic caused by SARS-CoV-2 necessitates innovative strategies for the rapid development of effective treatments. Computational methodologies, such as molecular modelling, molecular dynamics simulations, and artificial intelligence, have emerged as indispensable tools in the drug discovery process. This review aimed to provide a comprehensive overview of these computational approaches and their application in the design of antiviral agents for COVID-19.

Nasal Septal Ancient Schwannoma: Ancient and Rare.

Schwannoma is a rare benign neurogenic tumor arising from the Schwann cells of peripheral nerves. A 77-year-old man presented with progressively worsening left nasal block and hyposmia for the past six months. Nasal endoscopy revealed a polypoidal reddish mass occupying the left middle meatus.

Pathological analysis and antimicrobial susceptibility of Chryseobacterium balustinum RTFCP 298 isolated from diseased rainbow trout, Oncorhynchus mykiss.

In this study, six isolates of Chryseobacterium balustinum were characterized from diseased rainbow trout fingerlings. The virulence characteristics, pathogenicity, and antimicrobial susceptibility pattern of these isolates were investigated.
