Malnutrition remains a clinical challenge in AML patients undergoing autologous hematopoietic stem cell transplantation (ASCT), leading to physical deconditioning and prolonged hospitalization. Prospective data are mainly lacking to identify those patients who may particularly benefit from parenteral nutrition in this setting. This observational, non-randomized, retrospective, exploratory cohort study assessed the nutritional development in patients following high-dose chemotherapy (HDCT) with ASCT and explored the [...]

This study examines the effect of e-learning crack-up perception (ECUP) and fear of academic year loss (FAYL) on psychological distress (PD). The study also explores the impact of PD on students' academic performance (AP). It uses a quantitative method based on data collected from Egyptian medical university students using convenience sampling. The study utilized 313 cases to get the final results. Using path analysis through analysis of moment structures (AMOS) software, the study confirmed a positive effect o [...]

6q22.31q27 duplication and Xq28 deletion lead to two specific different rare chromosomal disorders. Partial trisomy 6q22.31q27 is a recognizable syndrome with a distinctive phenotype, and the most common finding in girls with Xqter deletions has been premature ovarian failure (POF) and secondary amenorrhea. To our knowledge, neither abnormality in one patient has yet been reported. A 10-year-old girl with de novo 6q22.31q27 duplication and Xq28 deletion was diagnosed by chromosomal microarray and confirmed by fluor [...]

This study evaluates how chromosomal factors affect assisted reproduction techniques (ART) challenges among infertile couples, impacting their chances of conception. Chromosomal abnormalities, a leading cause of pregnancy failure and miscarriages, were investigated in a four-year retrospective study involving 100 patients with a history of infertility and unsuccessful IVF treatment. Among these cases, nine (9%) displayed aberrant chromosomal patterns, including balanced translocations (5%), sex chromosome deletions [...]

High strength and good conductivity are both critical parameters for copper-based alloys for electrical and other technological applications. This study is aimed to produce copper alloys and metal matrix composites (MMCs) with enhanced physical properties. Cu-Ti-Ni ternary alloys and MMCs samples were sintered at 600 to 700°C using spark plasma sintering (SPS), with a heating rate of 100°C/minutes, uniaxial pressure of 50 MPa, and a holding time of 10 minutes. Scanning electron microscopy (FE-SEM) was used to exami [...]

Recent studies have identified that certain types of migraines, including frontal migraines, may be attributed to the irritation of specific extracranial nerves. This systematic review addresses the following questions: Which surgical techniques are most effective for chronic frontal migraines? How do combined surgical approaches compare to isolated procedures regarding efficacy and complication rates? Our objective is to comprehensively analyze surgical options for frontal migraines, including their success rates [...]

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]

Crohn’s disease is characterized by chronic intestinal inflammation that can result in significant morbidity and loss of intestinal function over time. Many novel treatments for Crohn’s disease are being developed, but a significant portion of patients still requires surgical therapy for structuring or penetrating disease. While the utility of esophagogastroduodenoscopy and ileocolonoscopy in inflammatory bowel disease patients is well established, new endoscopic techniques are being developed to help evaluate prev [...]

The present study investigated the co-gasification of two different lignites blended with the forest residue collected from the land restoration activity sites of open-pit mines located in the region of the Ptolemais basin in North Greece performed under the carbon dioxide stream. All samples were devolatilized in a fixed bed unit prior to the gasification evaluations. The gasification evaluations were performed using a thermal analysis system (TG/DTG) operated at temperatures of up to 1000 °C. The reactivity, [...]
