Squamate reptiles may have compensated for the lack of γδTCR with a duplication of the TRB locus.

Squamate reptiles are amongst the most successful terrestrial vertebrate lineages, with over 10,000 species across a broad range of ecosystems. Despite their success, squamates are also amongst the least studied lineages immunologically. Recently, a universal lack of γδ T cells in squamates due to deletions of the genes encoding the T cell receptor (TCR) γ and δ chains was discovered.

The impact of pediatric post-cardiac arrest care on survival: A multicenter review from the AHA get with the Guidelines®-resuscitation post-cardiac arrest care registry.

Aim: Adherence to post-cardiac arrest care (PCAC) recommendations is associated with improved outcomes for adults. We aimed to describe the survival impact of meeting American Heart Association (AHA) PCAC guidelines in children after cardiac arrest.

Methods: We conducted a retrospective study using Get With The Guidelines® Resuscitation's (GWTG®-R) registry to describe the PCAC of patients ≤ 18 years old who suffered an in-hospital or out-of-hospital cardiac arrest (IHCA or OHCA).

Insights from a century of data reveal global trends in ex situ living plant collections.

Ex situ living plant collections play a crucial role in providing nature-based solutions to twenty-first century global challenges. However, the complex dynamics of these artificial ecosystems are poorly quantified and understood, affecting biodiversity storage, conservation and utilization. To evaluate the management of ex situ plant diversity, we analysed a century of data comprising 2.

Mental Health Issues Associated With Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency.

Context: The goal of this review is to move beyond summarizing what is known about psychosexual development in females with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency-commonly studied as a natural experiment to understand prenatal androgen effects in 46,XX individuals. Instead, it will explore the various aspects of the condition that significantly impact the daily lives of both male and female patients and their families, with a particular focus on the implications for psychosocial, educational, and vocational adaptation.

Evidence Acquisition: This work represents a selective, yet balanced review of papers highlighting potential threats to positive psychological adaptation in both male and female individuals with CAH.
