Objectives: Exposure of spleen tissues to ionizing radiation during radiotherapy can induce cellular stress and immune-dysfunction leading to cellular senescence.

Introduction: The process of a cancerous development is facilitated by the accumulation of senescent cells. This justifies the incorporation of anti-senescent medications during splenic irradiation (SI).

This article reports a comparative prospective study aimed to explore and compare nurses' perceptions of bedside clinical handover in 3 different settings (emergency unit, ICU, and medical ward). Results revealed that the participant nurses' perceptions varied significantly for different aspects of the handover process. Our data demonstrate department-specific variations in perceptions related to the adequacy, organization, relevance, availability of charts, use of charts for review, ease of following the information, and timeliness of the information.

This investigation aimed to evaluate the impact of immersion (IM) riboflavin treatment on the hatchability, production efficiency, and carcass characteristics of Japanese quail eggs. A total of 260 eggs of Japanese quail birds were used for hatching and were randomly divided into 4 treatments with 5 replicates (13 eggs/replicate) in a fully randomized design. Hatching eggs were immersed in riboflavin for 2 min before incubation.

Purpose: Despite the effectiveness of ionizing radiation in treating cancer, it can damage healthy tissues in the vicinity. Due to the high radio-sensitivity of testicular tissues, radiation therapy may affect spermatogenesis, which may result in infertility. Hence, in this study testicular damage model is constructed to investigate the mitigation effect of Maca root powder and its potential radioprotective activity through both oxidative and endoplasmic reticulum (ER) stresses, besides the apoptotic pathway.

Several neurological disorders, neurodevelopmental disorders, and neurodegenerative disorders have a genetic element with various clinical presentations ranging from mild to severe presentation. Neurological disorders are rare multifactorial disorders characterized by dysfunction and degeneration of synapses, neurons, and glial cells which are essential for movement, coordination, muscle strength, sensation, and cognition. The cerebellum might be involved at any time, either during development and maturation or later in life.

Background: Self-medication (SM) is a growing phenomenon worldwide that has recently been classified as one of the most serious public health problems. SM can result in an incorrect self-diagnosis, inappropriate treatment, potential adverse reactions, interactions, and the masking of more sinister disease.

Objectives: To assess the prevalence of SM practices amongst healthcare professionals and the general population in Saudi Arabia and to identify the sociodemographic contributing factors to this practice.

This article reports a study aimed at developing and validating an evidence-based, shift-to-shift handover bundle for nurses and physicians to be used at shift changes in intensive care and emergency units. Deficient or absent clinical handovers, or failures to transfer information, responsibility, and accountability can have unwanted consequences for hospitalized patients, particularly those at critical areas. Clinical handovers are practiced every day, in many ways, in all institutional health care settings.

Radiotherapy is a very important tool in the treatment of cancer; nevertheless, its side effects are a hindrance to its use. The present study is designed to evaluate glucosamine effects against radiation-induced brain oxidative stress and depression-like effect in rats. Four groups of female Wister rats were used as control, irradiated (4 × 2 Gy), glucosamine (1 g/kg P.

Organisms frequently suffer negative effects from large doses of ionizing radiation. However, radiation is not as hazardous at lower doses as was once believed. The current study aims to evaluate the possible radio-adaptive effect induced by low-dose radiation (LDR) in modulating high-dose radiation (HDR) and N-nitrosodiethylamine (NDEA)-induced lung injury in male albino rats.

Article Synopsis
  • Lysosomal acid lipase (LAL) is crucial for breaking down triglycerides and cholesteryl esters in the lysosome, and a deficiency in this enzyme leads to a severe condition known as Wolman disease (WD), which can be fatal within a year if untreated.
  • This study focused on the clinical and genetic profiles of seven WD patients from five families in Egypt, employing advanced sequencing methods to identify genetic variants responsible for the disease.
  • Researchers discovered three disease-causing variants in the LIPA gene, including a novel variant that is likely pathogenic, which can aid in understanding the relationship between genetics and disease symptoms and improve genetic counseling efforts.
