Background: Cytokeratins are intracellular proteins known as diagnostic biomarkers or prognostic factors for certain cancers. Cytokeratin 19 (CK-19) expression has been proven to have prognostic value for some cancers, but its relationship with others, such as prostate cancer (PCa), remains unclear. This systematic review article aimed to examine the relationship between CK-19 expression and prostate adenocarcinoma (PAC).

Background: Chronic kidney disease (CKD) affects 10% of the global population and leads to end-stage renal disease (ESRD). Hemodialysis is a common treatment for ESRD, but patients often have low carnitine levels, leading to dyslipidemia, a risk factor for cardiovascular disease and the leading cause of mortality. This study aimed to assess the effects of L-carnitine on lipid profiles in adult hemodialysis patients.

This study aimed to evaluate the concentrations of both essential and non-essential elements in the breast milk of lactating mothers from Tehran, Iran, during the colostrum period. Neutron activation analysis (NAA) was used to measure the element concentrations. Additionally, the study assessed how these element concentrations were influenced by maternal factors such as age and economic status.

Article Synopsis
  • The integration of artificial intelligence (AI) in healthcare, particularly in radiology, has led to improved efficiency, diagnostic accuracy, and patient care, while also presenting new challenges.
  • Despite the potential benefits of AI in diagnosing conditions like intracranial hemorrhage and spinal fractures, limitations such as data imbalances and algorithm transparency hinder its widespread implementation.
  • Addressing these limitations is crucial for maximizing AI's advantages in emergency radiology and ensuring patient safety.

Introduction: This study investigates the long-term effectiveness and safety of endovenous laser treatment (EVLT) for chronic venous insufficiency (CVI), a condition commonly caused by dysfunctional valves in the venous circulation system.

Materials And Methods: In this retrospective cohort study, patients underwent EVLT and were followed up for successive short intervals and one last time after a median duration of 9-year postprocedural. Pre- and postprocedure duplex ultrasound was used to assess changes in the great saphenous vein (GSV) diameter, reflux, and saphenofemoral junction incompetence.

Article Synopsis
  • Bidirectional brain-machine interfaces (BMIs) utilize algorithms to connect brain activity with external devices, allowing for neural responses to control artificial limbs and provide feedback through electrical stimulation.
  • A new approach proposes a neural network model linking the sensory and motor cortex, utilizing a structured setup of neurons to improve the communication between the brain and mechanical devices.
  • Results show that the developed BMI algorithm enables real-time information exchange between brain activity and external devices, successfully controlling movements in both simulation and practical tests with anesthetized rats.
