Cryopreservation, the preservation of tissues at subzero temperatures, is a mainstay of brain banking that allows for the storage of brain tissue without the use of chemical fixatives. This is particularly important for molecular studies that are incompatible with tissue fixation. However, brain tissue is vulnerable to various forms of damage during the cryopreservation process, in particular due to the phase transition of water from a liquid to a solid state with the formation of ice crystals, which can disrupt cellular morphology.

However, other cellular targets for IL-25 remain poorly defined.
Objective: To investigate induction and expression of IL-25 receptor (IL-17RB) by B cells and evaluate responsiveness of IL-17RB-expressing B cells to IL-25 in vitro.
: Pediatrician recommendations are highly influential in parents' decisions to vaccinate their children against HPV. Unqualified, presumptive, and bundled recommendations (UPBRs) are associated with increased HPV vaccine uptake and are considered best practice. This study analyzes pediatricians' self-reported data to assess changes in UPBR use and the psychosocial determinants of UPBR use as a result of the implementation of a multi-level intervention, the Adolescent Vaccination Program (AVP).

Evidence indicates that metabolic factors, such as insulin resistance and dyslipidemia, which are highly prevalent in MDD, are independently associated with reward disturbances. Herein, we investigate the moderating effect of metabolic factors on effort-based decision-making in individuals with MDD.

Study Design: A didactic and simulation quality improvement initiative focused on teaching and reinforcing specific algorithms endorsed by the American Heart Association (AHA) to target resuscitation needs of older neonates including surgical and cardiac conditions. Qualitative and quantitative data pre and post implementation was audited.
