The Association Between Janus Kinase 2 and Factor V Leiden Mutations and Thrombotic Complications in Patients With Myeloproliferative Disorders: A Study From Saudi Arabia.

Background The Janus kinase 2 (JAK2) V617F mutations are related to increased thrombotic risk in patients with myeloproliferative disorders (MPDs). However, little is known about whether inherited thrombophilia represents an additive risk factor in mutated subjects. We addressed the association between combined mutations of JAK2 and factor V Leiden (FVL) and thrombotic complications in Saudi Arabian patients with MPDs.

Clinical, biochemical and molecular characteristics of classic homocystinuria in Saudi Arabia and the impact of newborn screening on prevention of the complications: A tertiary center experience.

Background: Classic homocystinuria (HCU) is a rare inborn metabolic disease that is generally asymptomatic at birth. If untreated, it can cause a wide range of complications including intellectual disability, lens dislocation, and thromboembolism. This study aimed to describe the natural history and the molecular findings of patients with HCU, and to assess the importance of early diagnosis.

ICT-based fluorescent nanoparticles for selective cyanide ion detection and quantification in apple seeds.

In this report, we successfully engineered a novel probe based on an acceptor-donor-acceptor (A-D-A) architecture featuring dicyanovinyl-substituted thieno[3,2-]thiophene, termed DCVTT. The designed probe self-assembles into luminous nanoparticles (DCVTT NPs) upon introducing mixed aqueous solutions. These fluorescent nanostructures served as a ratiometric probe for detecting cyanide (CN) ions in aqueous-based environments, owing to the robust Intramolecular Charge Transfer (ICT) characteristics of DCVTT.

Efficacy of Antibiotic Therapy Alone Versus Antibiotics With Percutaneous Drainage in Periappendiceal Abscess: A Systematic Review and Meta-Analysis.

Acute appendicitis is one of the most common surgical emergencies. Simple appendicitis can be a complicated periappendiceal abscess. Despite the fact that there are several treatment options for periappendiceal abscesses, there is no consensus on the optimal treatment method; some surgeons prefer appendectomy, while others prefer relying on non-operative approaches using antibiotic therapy with or without percutaneous drainage.

Design, Synthesis and Pro-Inflammatory Activity of Palmitoylated Derivatives of Thioglycolic Acid as New Immunomodulators.

The immune system is essential for the defense against infections and is critically implicated in various disorders, including immunodeficiency, autoimmunity, inflammation and cancer. The current study includes a new design of palmitoylated derivatives of thioglycolic acids (PTGAs) capable of triggering innate immune responses. The new series were accessible through a three-step synthetic route, including N-palmitoylation, Claisen-Schmidt condensation and thia-Michael addition.
