Autophagy is a critical cellular process that maintains homeostasis by recycling damaged or aberrant components. This process is orchestrated by a network of proteins that form autophagosomes, which engulf and degrade intracellular material. In cancer, autophagy plays a dual role: it suppresses tumor initiation in the early stages but supports tumor growth and survival in advanced stages.

Article Synopsis
  • Mutations in the PTEN gene are linked to serious neurodevelopmental disorders, primarily by causing hyperactivation of the mTOR pathway through its two complexes, mTORC1 and mTORC2.
  • Researchers used human neurons and neural precursor cells derived from pluripotent stem cells with PTEN mutations to observe disease characteristics like cellular overgrowth and hyperactivity.
  • Their study indicates that the combined activation of both mTORC1 and mTORC2 is crucial for the phenotypes associated with PTEN mutations, pointing to potential new therapeutic targets for treatment.

Background: Employee disengagement in healthcare and business is currently at unexceptionally high levels worldwide. Disengagement negatively impacts productivity, profitability, efficiency (waste reduction), innovation, quality, customer satisfaction and experience, staff well-being, safety, mortality, staff attendance, and turnover. Despite its serious detrimental impacts, no dedicated competency-based training curriculum exists for engagement as a competency.

seeds are used in the treatment of various diseases, especially diabetes and associated complications, in different parts of the world. The present study was undertaken to determine the hypolipidemic and antihyperlipidemic effects of methanolic extract of seeds in rats. The extract was subjected to LC-MS analysis to determine the chemical constituents.

Objectives: To perform a systematic review and meta-analysis of the techniques and outcomes associated with percutaneous decannulation of venoarterial extracorporeal membrane oxygenation (VA-ECMO) using the Manta vascular closure device.

Background: Peripheral VA-ECMO can be used to treat critically ill patients with conditions such as refractory cardiogenic shock. After percutaneous implantation of VA-ECMO, VA-ECMO can also be decannulated completely percutaneously by using a vascular closure device.

The brain is arguably the most complex part of the human body in form and function. Much remains unclear about the molecular mechanisms that regulate its normal and pathological physiology. This lack of knowledge largely stems from the inaccessible nature of the human brain, and the limitation of animal models.

Objectives: We aimed to evaluate neutrophil-to-lymphocyte ratio in children with acute heart failure due to dilated cardiomyopathy, to assess the predictive and prognostic values of neutrophil-to-lymphocyte ratio, and to correlate its levels with brain natriuretic peptide and other various data in these patients.

Method: We included 50 children with acute heart failure due to dilated cardiomyopathy as the patient group. Fifty healthy children of matched age and sex served as the control group.

Diarrheal disease continues to be a leading cause of death in children under five years old in developing countries, where it is responsible for the death of approximately half a million children each year. Establishing the cause of diarrheal disease can be difficult in developing areas due to the lack of diagnostic tests, and thus empirical therapies are often required. In these settings, the choice of antibiotic (or the choice to not give it) depends on suspected agents, host conditions and local epidemiology.

Studies in recent years have shown that aquatic pollution by microplastics (MPs) can be considered to pose additional stress to amphibian populations. However, our knowledge of how MPs affect amphibians is very rudimentary, and even more limited is our understanding of their effects in combination with other emerging pollutants. Thus, we aimed to evaluate the possible toxicity of polyethylene MPs (PE-MPs) (alone or in combination with a mix of pollutants) on the health of Physalaemus cuvieri tadpoles.

Green nanotechnology has attracted attention worldwide, especially in treating cancer and drug-resistant section 6 microbes. This work aims to investigate the anticancer activity of green silver nanoparticles synthesized by phycocyanin (SPAgNPs) on two cancer cell lines: Lung cancer cell line (A-549) and breast cancer cell line (MCF-7), compared to the normal human lung cell line (A138). We also aimed to investigate the bactericidal activity against ATCC29737, ATCC11778, ATCC8379, and , as well as the fungicidal activity against (ATCC6019) and .

Type 2 diabetes mellitus (T2DM) is a heterogeneous disease with numerous abnormal targets and pathways involved in insulin resistance, low-grade inflammation, oxidative stress, beta cell dysfunction, and epigenetic factors. Botanical drugs provide a large chemical space that can modify various targets simultaneously. (MA, golden chamomile) is a widely used herb in Middle Eastern communities for many ailments, including diabetes mellitus, without any scientific basis to support this tradition.

Dandy-Walker malformation is a group of brain malformations that sometimes present with psychotic features, violent and impulsive behavior, or mood symptoms. Here, we present a case report of a patient with Dandy-Walker malformation who presented with intermittent explosive disorder. A young man, aged 18 years, was brought to the author's hospital [Hamad Medical Corporation] with anger outbursts, irritable mood, and violent behavior.

Background: Self-medication and acquisition of over-the-counter (OTC) drugs are emerging community health issues. Besides being a cheap alternative for treating common illnesses, the behavior entails serious ramifications, such as medication wastage, increasing pathogen resistance, and adverse drug reactions. So, the purpose of the present study was to explore and understand the consumption of commonly used OTC drugs and dietary supplements in Dubai and also assess individuals' self-care behaviors related to OTC and dietary supplements.

Despite the toxicity of microplastics (MPs) in freshwater fish has been demonstrated in previous studies, their effects when mixed with other pollutants (organic and inorganic) are poorly understood. Thus, we aimed to test the hypothesis that the association of polyethylene MPs (PE-MPs) to a mix of emerging pollutants induces more adverse genotoxic, mutagenic, and redox unbalance effects in adult zebrafish (Danio rerio), after 15 days of exposure. Although the accumulation of MPs in animals was greater in animals exposed to PE-MPs alone, erythrocyte DNA damage (comet assay) and the frequency of erythrocytic nuclear abnormalities (ENAs) evidenced in zebrafish exposed to PE-MPs alone were as pronounced as those observed in animals exposed to the mix of pollutant (alone or in combination with MPs), which constitutes the big picture of the current study.
