Two novel BODIPY dyes, BOC3 and BC12, were synthesized with variable alkyl chains at terminal amide functional units. BC12, featuring a longer alkyl chain (-C12H25), formed a gel compared to BOC3, which has a shorter alkyl chain (-CH2OCH3), due to supra molecular self-assembly in film. Both dyes exhibited absorption peaks around 530 nm in the visible region, with a red shift of about 30 nm in the film state, essential for organic electronic applications.

Enteric fever is a significant health concern in endemic countries. While extensive research has been conducted to understand its presentation and outcomes in non-cancer patients, limited data exist on its impact on cancer patients. This descriptive study aims to investigate the clinical presentation and outcome in cancer patients.

  • Pakistan has been facing a significant outbreak of extensively drug-resistant (XDR) typhoid, and researchers investigated how the COVID-19 pandemic affected its spread from 2020 to 2022.
  • During the early COVID-19 period, typhoid cases declined due to restrictions and improved hygiene, though resistance to antibiotics like ceftriaxone continued to rise, indicating persistent XDR typhoid.
  • As pandemic restrictions eased in 2022, typhoid cases grew again, emphasizing the need for precise testing and vaccination to manage both diseases effectively.

Motivation: To study gene regulation through transcription factors and chromatin modifiers, a variety of genome-wide techniques are used. Recently, CUT&RUN-based technologies have become popular, but a pipeline for the comprehensive analysis of CUT&RUN datasets is currently lacking. Here, we present the "greenPipes" package, which includes fine-tuned parameters specifically for bioinformatic analyses of greenCUT&RUN and CUT&RUN datasets.

Purpose: Rare yeasts species are increasingly reported as causative agents of invasive human infection. Proper identification and antifungal therapy are essential to manage these infections. Candida blankii is one of these emerging pathogens and is known for its reduced susceptibility to multiple antifungals.

Article Synopsis
  • The COVID-19 pandemic has severely affected individuals with hematological malignancies due to their weakened immune systems, resulting in higher mortality rates and severe outcomes.
  • Data from the EPICOVIDEHA registry, which compiles COVID-19 cases from these patients worldwide, was collected from 2020 to 2022, including 8,767 cases from 152 centers across 41 countries.
  • Findings show a significant drop in critical infections and overall mortality rates, but hospitalization (especially in ICU) remains a serious risk factor; vaccination is linked to better survival outcomes, highlighting the need for ongoing monitoring and support for these patients.

Article Synopsis
  • The study aimed to evaluate the factors influencing pneumonia (PJP) in cancer patients, focusing on demographics, disease progression, complications, and treatment outcomes over four years at a cancer hospital in Lahore, Pakistan.
  • Out of 84 patients analyzed, a significant portion had hematological malignancies, with common symptoms being dyspnea, fever, and cough; serious complications included respiratory failure and a notable mortality rate of 32%.
  • Findings emphasize the need for early assessment and treatment of PJP in cancer patients, particularly those with blood-related cancers, as they face higher risks of severe outcomes.

Increasing pollution of plastic waste is one of the major global environmental threats, deteriorating our land, water and air. The shift towards biobased, biodegradable and compostable plastics is considered a green alternative to petroleum-based plastic due to its renewable source or biodegradability. However, there is a misconception about biodegradable plastics and their degradability and behaviour after service life.

Background: Glioblastoma is the most common and aggressive primary brain tumor with extremely poor prognosis, highlighting an urgent need for developing novel treatment options. Identifying epigenetic vulnerabilities of cancer cells can provide excellent therapeutic intervention points for various types of cancers.

Method: In this study, we investigated epigenetic regulators of glioblastoma cell survival through CRISPR/Cas9 based genetic ablation screens using a customized sgRNA library EpiDoKOL, which targets critical functional domains of chromatin modifiers.

Since the beginning of the COVID-19 pandemic, there has been an overall improvement in patient mortality. However, haematological malignancy patients continue to experience significant impacts from COVID-19, including high rates of hospitalization, intensive care unit (ICU) admissions, and mortality. In comparison to other haematological malignancy patients, individuals with chronic myeloid leukemia (CML) generally have better prognosis.

Salmonella Typhi infection in a patient in Pakistan initially responded to standard treatment but failed to respond to subsequent treatment. The first strain was susceptible to carbapenems and azithromycin; subsequent strains harbored the NDM-5 gene. Treatment with a combination of intravenous meropenem and colistin was successful.

Typhoid fever, caused by Salmonella enterica serovar Typhi, is a common cause of febrile illness, especially in lower middle-income countries. The only known reservoirs of this infection are humans, and it is prevalent in areas with limited availability of clean drinking water and sanitary conditions. Lately, extensively drug-resistant Salmonella ser.

The UTX/KDM6A histone H3K27 demethylase plays an important role in development and is frequently mutated in cancers such as urothelial cancer. Despite many studies on UTX proteins, variations in mRNA splicing have been overlooked. Using Nanopore sequencing, we present a comprehensive analysis of UTX/KDM6A splicing events in human cell lines and in tissue samples from bladder cancer cases and normal epithelia.

Background: The TAS2R38 gene carries markers for phenylthiocarbamide (PTC) sensitivity. Various studies have investigated the genotype-phenotype association pattern for bitter tasting ability and other factors in different populations. However, a paucity of such information for endogamous Indian populations is the reason behind this study.

Cleft lip and/or cleft palate (CL/P) is one of the most common congenital anomalies of the human face with a complex etiology involving multiple genetic and environmental factors. Several studies have shown the association of the paired box 7 ( ) gene with CL/P in different populations worldwide. However, the current literature reveals no reported case-parent trio studies to evaluate the association between the gene and the risk of nonsyndromic cleft lip and/or palate (NSCL/P) in the Indian population.

This research examines the impact of COVID-19 on food security in New York state and the innovative approaches employed by food assistance organizations to help address the changing and increasing demand for their services from March 2020 to May 2021. We examine the case study of New York's Capital District region through a qualitative approach. We find that there was a sharp increase in utilization of emergency services during spring of 2020, which tapered off in the summer and fall of 2020 but remained above the levels of need seen the previous year.
