Assessment of growth, biomass, and carbon sequestration potential of urban tree species in greenbelts.

This study assessed the growth, biomass, and carbon storage potential of four urban tree species-Pinus roxburghii, Broussonetia papyrifera, Jacaranda mimosifolia, and Eucalyptus camaldulensis-in Islamabad's greenbelts. Sampling was conducted using a quadrat method, covering five sites (F-9, G-8, H-8, I-8, Zero-Point), with 400 trees analyzed. Growth parameters such as diameter at breast height (DBH), height, aboveground biomass (AGB), aboveground carbon density (ACD), belowground carbon density (BCD), basal area (BA), and volume were measured.

V-ATPase Disassembly at the Yeast Lysosome-Like Vacuole Is a Phenotypic Driver of Lysosome Dysfunction in Replicative Aging.

Declines in lysosomal acidification and function with aging are observed in organisms ranging from yeast to humans. V-ATPases play a central role in organelle acidification and V-ATPase activity is regulated by reversible disassembly in many different settings. Using the yeast as a replicative aging model, we demonstrate that V-ATPases disassemble into their V and V subcomplexes in aging cells, with release of V subunit C (Vma5) from the lysosome-like vacuole into the cytosol.

Industrial prospects on regulatory gaps and barriers in pharmaceutical exports and their counteraction: Local experiential with global implication.

Background: The pharmaceutical sector in Pakistan has grown over a period with export potential, however, there are certain barriers in the framework that regulate the growth and export of domestically manufactured pharmaceuticals. The purpose of this study was to highlight the current challenges that hinder the export of pharmaceuticals, especially to the countries with stringent regulatory authorities (SRA), as perceived by the domestic pharmaceutical industry experts, and to highlight the facilitators that may help to resolve the identified challenges.

Methods: In a qualitative study, the data were collected from the consented experts from the pharmaceutical industries in Lahore, Karachi, Peshawar, and Quetta.

Exploring the Clinical Features, Management of Hypertension, and Predictors of Severity in Hospitalized Hypertensive COVID-19 Patients.

Background Hypertension significantly contributes to the severity, prolonged hospitalization, the need for intensive care, and mortality of COVID-19 patients. However, the data is still evolving. This study investigated the predictors of severity among hypertensive COVID-19 patients.
