Zinc-based fixative as a novel approach for histological preservation: A comparative study with formalin-based fixatives.

Background: Formalin is a widely used histological fixative despite its carcinogenic properties, inadequate nucleic acid preservation, and prolonged fixation time.

Aim: The study intended to prepare a novel zinc-based fixative that is, formalin-free, and cost-effective, provides optimal preservation, with rapid penetration rates, and enhanced Hematoxylin/Eosin-stained sections.

Methods: Liver, kidney, brain, and small intestine specimens were collected from 10 adult laboratory rats () and preserved in formalin 4%, formalin 10%, neutral buffered formalin (NBF), and the experimental EZAT solution.

A Repurposing Programme Evaluating Transdermal Oestradiol Patches for the Treatment of Prostate Cancer Within the PATCH and STAMPEDE Trials: Current Results and Adapting Trial Design.

Aims: Androgen deprivation therapy (ADT), usually achieved with luteinising hormone releasing hormone analogues (LHRHa), is central to prostate cancer management. LHRHa reduce both testosterone and oestrogen and are associated with significant long-term toxicity. Previous use of oral oestrogens as ADT was curtailed because of cardiovascular toxicity.

Healthcare systems data in the context of clinical trials - A comparison of cardiovascular data from a clinical trial dataset with routinely collected data.

Background: Routinely-collected healthcare systems data (HSD) are proposed to improve the efficiency of clinical trials. A comparison was undertaken between cardiovascular (CVS) data from a clinical trial database with two HSD resources.

Methods: Protocol-defined and clinically reviewed CVS events (heart failure (HF), acute coronary syndrome (ACS), thromboembolic stroke, venous and arterial thromboembolism) were identified within the trial data.

Magnetic Resonance Imaging Findings in High School Football Players: Brain and Cervical Spine.

Football exposes its players to traumatic brain, neck, and spinal injury. It is unknown whether the adolescent football player develops imaging abnormalities of the brain and spine that are detectable on magnetic resonance imaging (MRI). The objective of this observational study was to identify potential MRI signatures of early brain and cervical spine (c-spine) injury in high school football players.
