The major histocompatibility complex class I related protein (MR1) presents microbially derived vitamin B2 precursors to mucosal-associated invariant T (MAIT) cells. MR1 can also present other metabolites to activate MR1-restricted T cells expressing more diverse T cell receptors (TCRs), some with anti-tumor reactivity. However, knowledge of the range of the antigen(s) that can activate diverse MR1-reactive T cells remains incomplete.

View Article and Find Full Text PDFAvapritinib (AVA) is the first medication authorized by the US-FDA in 2020 for the management of gastrointestinal stromal tumours (GISTs) that can't be treated by surgery. Cancer is among the most common causes of death worldwide and is the second most common cause of death after cardiovascular disease. Therefore, a quick, easy, sensitive, and straightforward fluorimetric approach was used to analyse AVA in pharmaceutical materials and blood plasma (pharmacokinetic).

This study introduces the first and unique Molecular-mass-Related Fluorescence Sensor as the first fluorimetric strategy for determining amlodipine. An environmentally friendly, single-step, and direct spectrofluorimetric approach was utilized to evaluate the analyte. In an acidic setting, combining the amlodipine medication and the fluorescent dye Cilefa Pink B generated an instantaneous ultra-fluorescent product.

Method: The quasi-experientialstudy was conducted at the Paediatric Medical Department of Kafrelsheikh University Hospital, Egypt, from November 2021 to April 2022, and comprised children of either gender aged 6-12 years. The subjects were randomised into flippits group A, virtual reality group B and control group C in which only traditional care was provided.
Objectives: To evaluate the relationship between left ventricular hypertrophy (LVH) and coronary artery bypass grafting (CABG) procedure especially on the early outcome during the first 6 months following surgical intervention.
Method: This prospective cohort study included 82 patients with coronary artery disease indicating CABG. These patients were admitted, operated and followed -up in cardiothoracic surgery departmentsin the faculty of medicine, Kafrelsheikh university hospitals in the period from April 2019 till November 2021.
Objectives: To assess safety; efficacy and efficiency of mini-sternotomy in aortic valve replacement in comparison to conventional sternotomy on short term follow up.
Method: This comparative study between 45 patients having aortic valve replacement via fullsternotomy versus 45 others planned for upper j-shaped mini-sternotomy, was conducted from May 2019 to February 2022 in Kafrelsheikh university hospital, Egypt. Data was collected and statistically analysed to assess outcomes.
Objectives: To compare the outcome of off-pump and on-pump coronary artery bypass graftsurgery in patients with left main coronary artery disease.
Methods: The randomised, controlled, prospective, multicentric study was conducted in 2020 during the period from January 2020 to December 2020 at Kafrelsheikh University Hospital, International Cardiac Centre and Alexandria New Medical Centre, Egypt, and comprised patients with left main coronary artery disease who underwent coronary artery bypass graftsurgery. The patients were randomised to on-pump surgery group I (Control Group) and off-pump surgery group II(Interventional Group).
Purpose: For patients with a failed forearm autogenous fistula (AF) and an exhausted cephalic vein, there is controversy about whether a brachial basilic AF with transposition or an arteriovenous prosthetic bridging graft (BG) must be the second vascular access option. This work measured and compared these two modalities according to patency rates, complications, and revisions.
Patients And Methods: A retrospective study of 104 cases that had either a brachial basilic AF (72) or an Arteriovenous BG (32).
