We report light collimation from a point source without the space normally needed for fan-out. Rays emerge uniformly from all parts of the surface of a blunt wedge light-guide when a point source of light is placed at the thin end and the source's position determines ray direction in the manner of a lens. A lenticular array between this light-guide and a liquid crystal panel guides light from color light-emitting diodes to designated sub-pixels thereby removing the need for color filters and halving power consumption but we foresee much greater power economies and wider application.

Repurposing the prostaglandin analogue treprostinil and the calcium-sensing receptor modulator cinacalcet to revive cord blood as an alternate source of hematopoietic stem and progenitor cells for transplantation.

Objective: The expanding field of hematopoietic cell transplantation (HCT) for non-malignant diseases, including those amenable to gene therapy or gene editing, faces challenges due to limited donor availability and the toxicity associated with cell collection methods. Umbilical cord blood (CB) represents a readily accessible source of hematopoietic stem and progenitor cells (HSPCs); however, the cell dose obtainable from a single cord blood unit is frequently insufficient. This limitation can be addressed by enhancing the potency of HSPCs, specifically their capacity to reconstitute hematopoiesis.

Background: Addressing perinatal psychological distress in Sierra Leone faces challenges due to the lack of culturally appropriate assessment tools, despite recent WHO recommendations for screening during the pre- and postpartum periods. While high-income countries use tools like the Edinburgh Postnatal Depression Scale or Patient Health Questionnaire-9 (PHQ-9), their cross-cultural validity and efficacy in developing countries are uncertain. The aim of this study was to address this gap by developing a functional assessment tool, culturally appropriate screening tool for perinatal psychological distress, and validate it with the PHQ-9.

U32 is an industrial strain capable of producing therapeutically useful rifamycin SV. In early days of fermentation studies, nitrate was found to increase the yield of rifamycin along with globally, affecting both carbon and nitrogen metabolism in favor of antibiotic biosynthesis; thus, the (NSE) hypothesis was proposed. Although GlnR is likely the master regulator of the pleotropic effect of NSE, the global metabolism affected by NSE has never been systematically examined.

Objectives: Occupational hearing loss is a significant problem worldwide despite the fact that it can be mitigated by the wearing of hearing protection devices (HPDs). When surveyed, workers frequently report that worsened work performance while wearing HPDs is one reason why they choose not to wear them. However, there have been few studies to supplement these subjective reports with objective measures.

A substantial number of patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) undergo a nephrectomy, especially in work-up for a kidney transplantation. Currently, there is no evidence-based algorithm to guide clinicians which patients should undergo nephrectomy, the optimal timing of this procedure, or the preferred surgical technique. This systematic review-based consensus statement aimed to answer important questions regarding nephrectomy in ADPKD.
