Bile's Hidden Weapon: Modulating the Microbiome and Tumor Microenvironment.

The human gut microbiome is a dynamic and intricate ecosystem, composed of trillions of microorganisms that play a pivotal role in maintaining overall health and well-being. However, the gut microbiome is constantly exposed to various environmental factors, including the bile produced by the liver, which can significantly impact its composition and function. Bile acids, secreted by the liver and stored in the gallbladder, modulate the gut microbiome, influencing its composition and function.

Background: Increased attention among healthcare workers, particularly nurses, is crucial for preventing medical errors and patient harm. This study uses an objective approach that overcomes the limitations of the subjective self-report measures employed in prior research on nurses' attention.

Methods: This cross-sectional study was conducted from January to March 2023 among 108 nurses at Besat Hospital in Tehran, Iran.

A national platform for advancing self-care processes for the most common illnesses and conditions: designing, evaluating, and implementing.

Background: Effective self-care practices are crucial for maintaining health and well-being, as inadequate self-care can lead to increased health risks and decreased overall quality of life. To address these issues, one promising approach involves leveraging progressive web app (PWA) platforms to educate and empower individuals with necessary self-care services. This study aims to design, implement, and evaluate a national self-care PWA platform, aiming to enhance accessibility and effectiveness in promoting health and self-care practices.

CRISPR-Cas9 in basic and translational aspects of cancer therapy.

Introduction: The discovery of gene editing techniques has opened a new era within the field of biology and enabled scientists to manipulate nucleic acid molecules. CRISPR-Cas9 genome engineering has revolutionized this achievement by successful targeting the DNA molecule and editing its sequence. Since genomic changes are the basis of the birth and growth of many tumors, CRISPR-Cas9 method has been successfully applied to identify and manipulate the genes which are involved in initiating and driving some neoplastic processes.

Identification of meat adulteration in minced meat samples labeled as beef and mutton in Tehran stores using duplex PCR.

Food fraud and profiteering are becoming increasingly common in the meat industry. Therefore, it is essential to identify such practices to prevent consumer deception and maintain food safety. This study aimed to determine the contents of minced meat samples labeled as beef and mutton in retail stores across Tehran province, Iran, to identify instances of meat adulteration.

Non-Mutational Changes of Autophagy Marker LC3A in Patients with Acute Myeloid Leukemia; Effect of DNA Methylation and Expression Level of LncRNA-GAS5 and miRNA-155-5p, A Case Control Study.

Unlabelled: Clinical translation of autophagy modulators is tied to thoroughly acquainted with the precise state of this process and its regulators in a particular cancer. LC3Av1 is a marker of autophagosome membrane that has been contributed with pathobiology of myriad of human cancers. In the present study, we examined the effect of promoter methylation and miR-155 and LncRNA-GAS5 (GAS5) expression levels on transcription of LC3Av1 in AML patients.

Nanodiagnostics in global eradication of hepatitis C virus.

Hepatitis C, caused by the hepatitis C virus (HCV), is a prevalent liver disease with severe outcomes, including cirrhosis and hepatocellular carcinoma. Traditional diagnostic methods primarily detect antiviral antibodies (anti-HCV) or viral RNA, but these approaches have limitations. Anti-HCV antibodies may take 2-4 weeks to develop in acute cases and can be absent in some individuals, leading to undiagnosed early-stage infections.
