Genomic characterization of cervical lymph node metastases in papillary thyroid carcinoma following the Chornobyl accident.

Nat Commun

June 2024

Laboratory of Genetic Susceptibility, Division of Cancer Epidemiology and Genetics, National Cancer Institute, National Institutes of Health, Bethesda, MD, USA.

Article Synopsis
  • Childhood exposure to radioactive iodine from the Chornobyl accident increases the risk of papillary thyroid carcinoma (PTC), particularly in younger individuals.
  • A study of 428 PTC cases found that cervical lymph node metastases (cLNM) were more common in PTC with certain genetic fusions compared to mutations, and this frequency varied significantly by specific gene types.
  • Molecular profiling of the cLNM showed strong genetic concordance with primary PTCs and identified 17 differentially expressed genes, pointing to potential biological mechanisms in PTC metastasis that require further investigation.

BMC Endocr Disord

June 2024

Endocrine Research Center, Institute of Endocrinology and Metabolism, Iran University of Medical Sciences, Tehran, Iran, No. 10, Firoozeh St., Vali-asr Ave., Vali-asr Sq, Tehran, Iran.

Objective: Activating mutation in Ubiquitin-specific peptidase (USP8) is identified to enhance cell proliferation and adrenocorticotropic hormone (ACTH) secretion from corticotroph pituitary adenoma. We investigated the USP8 variant status in a population of Iranian people with functional corticotroph pituitary adenoma (FCPA). Moreover, a systematic review was conducted to thoroughly explore the role of USP8 variants and the related pathways in corticotroph adenomas, genotype-phenotype correlation in USP8-mutated individuals with FCPA, and the potential role of USP8 and epidermal growth factor receptor (EGFR) as targeted therapies in PFCAs.

Article Synopsis
  • - The study aimed to assess how European thyroid specialists view levothyroxine (LT4) treatment for euthyroid women with positive thyroid peroxidase antibodies (TPOAb) to improve fertility, as current evidence does not support this practice.
  • - An international survey (THESIS) revealed that 42.8% of over 2,316 respondents believe LT4 might be indicated for these patients, with significant variation across countries, highlighting a range from 22.9% to 83.7% of positive responses.
  • - Factors such as gender, age, and clinical experience influenced opinions; younger specialists and those who treat more thyroid patients were more likely to consider LT4, raising concerns about potential overtreatment risks in

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality worldwide, highlighting the urgent need for advancements in risk assessment and management strategies. Although significant progress has been made recently, identifying and managing apparently healthy individuals at a higher risk of developing atherosclerosis and those with subclinical atherosclerosis still poses significant challenges. Traditional risk assessment tools have limitations in accurately predicting future events and fail to encompass the complexity of the atherosclerosis trajectory.

Renilla luciferase catalyzes the oxidation of coelenterazine to coelenteramide and results in the emission of a photon of light. Although Renilla luciferase has various applications in biotechnology, its low thermal stability limits the development of its applications. Arginine is a well-known stabilizing amino acid that plays a key role in protein stabilization against inactivation.

Although childhood exposure to radioactive iodine-131 (I-131) is an established risk factor for thyroid cancer, evidence for an association with thyroid nodules is less clear. The objective of this study is to evaluate the association between childhood I-131 exposure and prevalence of ultrasound-detected thyroid nodules overall and by nodule histology/cytology (neoplastic/suspicious/non-neoplastic), size (<10 mm/≥10 mm), and number (single/multiple). This is a cross-sectional study of radiation dose (mean = 0.

Objective: Intraocular retinoblastoma (RB) is common in kids. Although the cause of this disease is a mutation in the RB1 gene, the formed cancerous mass in different patients is seen in non-invasive states, limited to the ocular cavity or in invasive states distributed to other parts of the body. Because this tumor's aggressiveness cannot be predicted early, these patients receive systemic chemotherapy with multiple drugs.

Background: Metabolic plasticity gives cancer cells the ability to shift between signaling pathways to facilitate their growth and survival. This study investigates the role of glucose deprivation in the presence and absence of beta-hydroxybutyrate (BHB) in growth, death, oxidative stress and the stemness features of lung cancer cells.

Methods And Results: A549 cells were exposed to various glucose conditions, both with and without beta-hydroxybutyrate (BHB), to evaluate their effects on apoptosis, mitochondrial membrane potential, reactive oxygen species (ROS) levels using flow cytometry, and the expression of CD133, CD44, SOX-9, and β-Catenin through Quantitative PCR.

This mini-review analyzed two approaches to screening bacterial contamination and utilizing pathogen reduction technology (PRT) for Platelet concentrates (PCs). While the culture-based method is still considered the gold standard for detecting bacterial contamination in PCs, efforts in the past two decades to minimize transfusion-transmitted bacterial infections (TTBIs) have been insufficient to eliminate this infectious threat. PRTs have emerged as a crucial tool to enhance safety and mitigate these risks.

Pathol Res Pract

May 2024

Research Center for Biochemistry and Nutrition in Metabolic Diseases, Institute for Basic Sciences, Kashan University of Medical Sciences, Kashan, Iran. Electronic address:

Article Synopsis
  • Long non-coding RNAs (lncRNAs) show promise as predictive markers for gastric cancer, and the natural compound coumarin may enhance this effect.
  • The study investigated how coumarin impacted three specific lncRNAs (BANCR, MALAT1, and FER1L4) and their target genes (PTEN, p-PI3K, and p-AKT) in AGS gastric cancer cells using various assays.
  • Results indicated that coumarin decreased cell viability, reduced expression of target mRNAs linked to BANCR, and led to lower protein levels of PTEN, p-PI3K, and p-AKT, suggesting coumarin could be a viable treatment option for gastric cancer.

Barriers to the Use of Insulin Therapy and Potential Solutions: A Narrative Review of Perspectives from the Asia-Pacific Region.

Diabetes Ther

June 2024

Unidad de Investigación en Enfermedades Metabólicas, Departamento de Endocrinología y Metabolismo, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.

The rising prevalence of type 2 diabetes (T2D) is posing major challenges for the healthcare systems of many countries, particularly in the Asia-Pacific Region, in which T2D can present at younger ages and lower body mass index when compared with Western nations. There is an important role for insulin therapy in the management of T2D in these nations, but available evidence suggests that insulin is under-utilized and often delayed, to the detriment of patient prognosis. The authors of this article gathered as an advisory panel (representative of some of the larger Asia-Pacific nations) to identify their local barriers to insulin use in T2D, and to discuss ways in which to address these barriers, with their outputs summarized herein.

Article Synopsis
  • The study aimed to evaluate the effectiveness of various basal insulins, revealing that existing treatment guidelines do not clearly distinguish the best options for patients starting insulin therapy.
  • A comprehensive analysis included 44 randomized controlled trials involving nearly 24,000 participants to assess outcomes like HbA1c levels, weight changes, and hypoglycemia.
  • Results indicated no significant difference in HbA1c reduction among the insulins, but insulin glargine (300 U/mL) led to less weight gain compared to others, while IDeg insulins showed fewer hypoglycemic events than NPH and lispro, although with low certainty in the findings.
