Viral diseases are a serious threat to humans while the most antiviral drugs have low efficiency and side effects on human health. Therefore, using microbial biopolymers as the drugs alternate to treat viral infections seems cost-effective and human friendly option. In the present study, thirty-four exopolysaccharides (EPSs) producing bacteria were isolated, and EPSs production capacity of five salt-tolerant isolates was determined under 0, 100 and 150 mM NaCl.

Article Synopsis
  • Fossil fuels, while essential energy sources, release significant sulfur when burned, contributing to air pollution and prompting increasing demand for fuels with ultra-low sulfur content.
  • Microorganisms effectively remove sulfur through biodesulfurization, targeting thiophenic structures like dibenzothiophene (DBT) found in coal and oil.
  • The study used surface-enhanced Raman spectroscopy (SERS) and multivariate data analysis techniques to identify and characterize DBT desulfurizing bacteria, achieving high accuracy and sensitivity in differentiating these species for better biodesulfurization strategies.

Human activities and climate change have resulted in frequent and intense weather fluctuations, leading to diverse abiotic stresses on crops which hampers greatly their metabolic activities. Heat stress, a prevalent abiotic factor, significantly influences cotton plant biological activities resulting in reducing yield and production. We must deepen our understanding of how plants respond to heat stress across various dimensions, encompassing genes, RNAs, proteins, metabolites for effective cotton breeding.

Mucilage is a gelatinous mixture of polysaccharides secreted from the seed coat and/or pericarp of many plant seeds when soaked in water. Mucilage affected seed germination while maintaining hydration levels during scarcity. Cydonia oblonga (quince) seeds are natural hydrocolloids extruding biocompatible mucilage mainly composed of polysaccharides.

Cotton (Gossypium hirsutum) is an economically potent crop in many countries including Pakistan, India, and China. For the last three decades, cotton production is under the constant stress of cotton leaf curl disease (CLCuD) caused by begomoviruses/satellites complex that is transmitted through the insect pest, whitefly (Bemisia tabaci). In 2018, we identified a highly recombinant strain; Cotton leaf curl Multan virus-Rajasthan (CLCuMuV-Raj), associated with the Cotton leaf curl Multan betasatellite-Vehari (CLCuMuB).

October 2024

Department of Physics, Islamia College Peshawar, Khyber Pakhtunkhwa 25120, Pakistan.

Fluorescence spectroscopy coupled with a random forest machine learning algorithm offers a promising non-invasive approach for diagnosing glycosuria, a condition characterized by excess sugar in the urine of diabetic patients. This study investigated the ability of this method to differentiate between diabetic and healthy control urine samples. Fluorescent spectra were captured from urine samples using a Xenon arc lamp emitting light within the 200 to 950 nm wavelength range, with consistent fluorescence emission observed at 450 nm under an excitation wavelength of 370 nm.

  • Hereditary neurodevelopmental disorders (NDDs) are common in serious pediatric illnesses, and irregular myelination may contribute to their development.
  • A Pakistani family with NDDs underwent whole exome sequencing, revealing a novel homozygous variant in the DOP1A gene that could disrupt protein interactions, potentially affecting myelin formation.
  • The study suggests that deficiencies in myelinogenesis, particularly during fetal and early development stages, may lead to NDDs, highlighting DOP1A as a significant gene in these conditions.
