Background: The COVID-19 pandemic disrupted the provision of sexual and reproductive health services, including contraceptive and family planning (FP) services. The World Health Organization conducted a multi-country study in India, Nigeria and Tanzania to assess the impact of the pandemic on the health system's capacity to provide contraceptive and FP services. In this paper, we share the results of a qualitative study aimed at understanding clients' perspectives at the primary healthcare level on accessing contraceptive services in COVID-19-affected areas in the three aforementioned countries.

Background: A DNA barcode is a short DNA fragment used to classify and identify specific organisms, taking advantage of the specificity and diversity inherent in biological molecules. Since Herbert introduced the concept in 2003, DNA barcoding has been increasingly used in precision medicine and related fields, including species identification and environmental monitoring, over the past few decades. Although numerous molecular diagnostic techniques have emerged, many face notable obstacles such as sensitivity to handling conditions, high expenses, and limitations in accuracy.

Radioresistance poses a significant obstacle in the management of Non-Small Cell Lung Cancer (NSCLC), often diminishing the effectiveness of radiotherapy and leading to treatment failures and adverse clinical outcomes. This study develops radioresistant NSCLC models, revealing that Secreted Protein Acidic and Rich in Cysteine (SPARC) as a crucial modulator of this resistance, through the inhibition of ferroptosis. To address this radioresistance, we propose a novel ferroptosis-oriented radiosensitization strategy specifically designed to enhance radiotherapy effectiveness in radioresistant NSCLC.

An increase in para-chloro-meta-xylenol (PCMX) pollution presents a significant obstacle to ecological security. The present study employed a series of microcosmic experiments to investigate the temporal dynamics of NO emissions and key genes involved in nitrogen cycle during the biodegradation process of PCMX. The results demonstrated that the degradation of PCMX exhibited first-order kinetics, with a calculated half-life of 231 days.

Background: ST-elevation myocardial infarction (STEMI) is a major cardiac event that requires rapid reperfusion therapy. The same reperfusion mechanism that minimizes infarct size and mortality may paradoxically exacerbate further cardiac damage-a condition known as reperfusion injury. Oxidative stress, calcium excess, mitochondrial malfunction, and programmed cell death mechanisms make myocardial dysfunction worse.
