  • Laryngeal cancer is a significant form of advanced head and neck cancer, often treated with invasive methods like total laryngectomy, which can lead to complications such as hypocalcemia, a condition of low calcium levels in the blood.
  • This study analyzed 50 laryngectomy patients over eight years, focusing on demographic and medical data, to examine the prevalence and risk factors for post-operative hypocalcemia.
  • Results indicated that factors like neck dissection, low pre-operative calcium levels, previous radiotherapy, and total thyroidectomy are significant predictors of hypocalcemia after surgery, highlighting the necessity for careful monitoring of calcium levels in affected patients.

Psoriasis is a complex inflammatory skin disease manifested by altered proliferation and differentiation of keratinocytes with dysfunctional apoptosis. This study aimed to identify regulatory factors and comprehend the underlying mechanisms of inefficient apoptosis to open up promising therapeutic approaches. Incorporating human protein interactions, apoptosis proteins, and physical relationships of psoriasis-apoptosis proteins helped us to generate a psoriasis-apoptosis interaction (SAI) network.

  • Non-functioning pituitary adenomas (NFPAs) are tumors that don't secrete hormones, but genes and long non-coding RNAs (lncRNAs) linked to these tumors may show dysregulation.
  • A study explored potential biomarkers involving regulatory lncRNAs associated with hub genes STAT3 and EGFR, finding a consistent down-regulation in NFPAs compared to normal adjacent tissues, except for one lncRNA (FALEC).
  • The research indicated that the expression levels of specific lncRNAs and genes could effectively differentiate NFPAs from normal tissues, suggesting a role for these markers in understanding NFPA pathogenesis.

Introduction: It is well known that peripheral artery disease (PAD) and coronary artery disease (CAD) coexist and therefore, patients diagnosed with PAD have an increased chance of developing concomitant CAD. CAD-related complications could be a leading cause of postoperative mortality in individuals with PAD undergoing vascular surgery. We present a case series of 48 patients who underwent coronary angiography before vascular surgery and an updated review of previous reports to determine the prevalence of concomitant CAD in a convenience sample of Iranian patients.

Backgrounds And Objective: Statins, inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase, are pivotal in managing hypercholesterolemia and reducing cardiovascular risk. While rosuvastatin demonstrates superior efficacy and tolerability compared to other statins, its safety profile in elderly patients older than 75 years old with acute coronary syndrome (ACS) remains underexplored. So, the objective of this study is to evaluate the frequency of adverse reactions and investigate the efficacy of high-dose rosuvastatin on lipid profiles in elderly patients aged over 75 with ACS.

A zoonotic disease called brucellosis can cause flu-like symptoms and heart inflammation. The bacteria responsible for this disease can also enter the brain, causing a condition called neurobrucellosis that can result in long-term neurological problems. In this study, researchers aimed to determine the changes in the hippocampal cells of rats infected with Brucella.

Background And Objective: Autosomal recessive genetic disorders pose significant health challenges in regions where consanguineous marriages are prevalent. The utilization of exome sequencing as a frequently employed methodology has enabled a clear delineation of diagnostic efficacy and mode of inheritance within multiplex consanguineous families. However, these aspects remain less elucidated within simplex families.

Alzheimer's disease (AD) is a progressive disease that causes an impairment of learning and memory. Despite the highly complex pathogenesis of AD, amyloid beta (Aβ) deposition and neurofibrillary tangles (NFTs) formation are the main hallmarks of AD. Neuroinflammation also has a crucial role in the development of AD.

Synaptic plasticity is believed to underlie the cellular and molecular basis of memory formation. Mitochondria are one of the main organelles involved in metabolism and energy maintenance as plastic organelles that change morphologically and functionally in response to cellular needs and regulate synaptic function and plasticity through multiple mechanisms, including ATP generation, calcium homeostasis, and biogenesis. An increased neuronal activity enhances synaptic efficiency, during which mitochondria's spatial distribution and morphology change significantly.
