Thyroid Hormone Replacement Dosing after Bariatric Surgery in Patients with Primary Hypothyroidism And Severe Obesity: Tehran Obesity Treatment Study.

Obesity and hypothyroidism are common medical conditions that are associated with each other. Bariatric surgery (BS) is a common approach used to achieve substantial weight loss in obese patients. However, there is limited evidence regarding the need for postsurgery levothyroxine (LT4) dose adjustment in patients with hypothyroidism undergoing BS.

Umbilical cord mesenchymal stem cells: A powerful fighter against colon cancer?

Colon cancer (CC) stands as one of the most common malignancies related to the gastrointestinal system, whose increasing incidence and death rates have been reported all over the world. Standard treatments for fighting cancers like CC comprise surgical approaches, chemotherapy, and radiotherapy, which are suggested by clinicians according to patients' conditions and disease stages. However, patients who utilize these modalities may suffer from serious side effects and adverse outcomes, for example, toxicity and tumor recurrence, as well as a low 5-year survival rate.

Potential of Natural Products in the Treatment of Glioma: Focus on Molecular Mechanisms.

Despite the waning of traditional treatments for glioma due to possible long-term issues, the healing possibilities of substances derived from nature have been reignited in the scientific community. These natural substances, commonly found in fruits and vegetables, are considered potential alternatives to pharmaceuticals, as they have been shown in prior research to impact pathways surrounding cancer progression, metastases, invasion, and resistance. This review will explore the supposed molecular mechanisms of different natural components, such as berberine, curcumin, coffee, resveratrol, epigallocatechin-3-gallate, quercetin, tanshinone, silymarin, coumarin, and lycopene, concerning glioma treatment.

Association of Functional Genetic Variations in Uric Acid Transporters with the Risk of Idiopathic Male Infertility: A Genetic Association Study and Bioinformatic Analysis.

Uric acid plays an important role in sustaining and improving sperm morphology, viability, and motility. It is known that SLC2A9 and ABCG2 protein are the main urate transporter and genetic variations in these genes could be associated with the levels of serum uric acid. This study aimed to investigate the association between single-nucleotide polymorphisms (SNPs) SLC2A9-rs16890979, SLC2A9-rs3733591, ABCG2-rs2231142, and ABCG2-rs2231137 with male infertility.

Gelatin-based nanoparticles and antibiotics: a new therapeutic approach for osteomyelitis?

The result of infection of bone with microorganisms is osteomyelitis and septic arthritis. Methicillin-resistant (MRSA) is responsible for most of its cases (more than 50%). Since MRSA is resistant to many treatments, it is accompanied by high costs and numerous complications, necessitating more effective new treatments.

Antimicrobial susceptibility and virulence gene analysis of species causing dysentery in Iranian children: Implications for fluroquinolone resistance.

species significantly impact global health due to their role in diarrheal diseases. A 2019-2022 cross-sectional study on 432 stool samples from pediatric patients in Mashhad, Iran, identified spp. and tested their susceptibility to 12 antimicrobials by the disk diffusion method.

Relationship Between Ankylosing Spondylitis and Cerebrovascular Disorders: A Systematic Review.

Cerebrovascular events are linked to ankylosing spondylitis. Accelerated atherosclerosis and endothelial dysfunction against a backdrop of inflammation have been widely blamed for the increased cerebrovascular risk in ankylosing spondylitis. The absence of a comprehensive review encouraged us to consider the link between ankylosing spondylitis and cerebrovascular diseases.

Telomerase and mitochondria inhibition promote apoptosis and TET2 and ANMT3a expression in triple negative breast cancer cell lines.

Introduction: High metastasis, resistance to common treatments, and high mortality rate, has made triple-negative breast cancer (TNBC) to be the most invasive type of breast cancer. High telomerase activity and mitochondrial biogenesis are involved in breast cancer tumorigenesis. The catalytic subunit of telomerase, telomerase reverse transcriptase (hTERT), plays a role in telomere lengthening and extra-biological functions such as gene expression, mitochondria function, and apoptosis.

Clues of HLAs, metabolic SNPs, and epigenetic factors in T cell-mediated drug hypersensitivity reactions.

Drug hypersensitivities are common reactions due to immunologic responses. They are of utmost importance because they may generate severe and fatal outcomes. Some drugs may cause Adverse Drug Reactions (ADRs), such as drug hypersensitivity reactions (DHRs), which can occur due to the interaction of intact drugs or their metabolites with Human Leukocyte Antigens (HLAs) and T cell receptors (TCRs).
