Development and evaluation of silver-infused Biopolymer coated cotton wound dressings as possible wound healing material.

Wound management is a critical clinical issue, with substantial economic and social implications. Traditional dressings often lead to poor healing, impacting the effective wound repair is an ongoing challenge. So, this research aimed to investigate the development of a novel medical textile auxiliary in the form of a padded cotton bandage coated with a blend of agricultural biopolymers (xanthan gum and gum arabic) containing AgNPs with an emphasis on environmental friendliness and sustainability.

A nature-based closed-loop wastewater treatment system at vehicle-washing facilities: From linear to circular economy.

Pakistan, among the top five most water-stressed nations globally, grapples with water scarcity owing to inadequate treatment infrastructure and groundwater overextraction. We demonstrate a successful nature-based closed-loop system to treat wastewater from urban vehicle-washing facilities, previously reliant on groundwater. An eco-friendly integrated system containing floating treatment wetlands (FTWs), subsurface flow constructed wetlands (SSF-CWs), and sand filtration (SF) was designed and installed at three vehicle-washing facilities for wastewater treatment and reuse in a loop.

Correlation of Serum Erythropoietin Levels with Different Stages of Diabetic Retinopathy.

Objective: To determine the correlation of serum erythropoietin concentration with diabetic retinopathy in patients with type 2 diabetes mellitus.

Study Design: Cross-sectional study. Place and Duration of the Study: Department of Chemical Pathology and Endocrinology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from July to December 2021.

Determination of pesticide residues in dates using UHPLC-QqQ-MS/MS: method development and validation.

A modified, efficient, and sensitive acetate-buffered QuEChERS extraction method was developed for the quantitative study of 16 commonly applied multiclass pesticides on date palm fruit. The date palm fruit samples were rehydrated by adding water during comminution. Samples were extracted with acidified acetonitrile, buffered with acetate salt.
