Long-acting injectable PrEP could offer an alternative to daily oral PrEP, improve adherence and protection, if found acceptable, safe and effective. HPTN 077 evaluated injectable cabotegravir safety, tolerability and pharmacokinetics among HIV-uninfected males and females in sequentially-enrolled cohorts of two dosing strategies. We compared acceptability of product attributes, prevention preferences and future interest in injectable PrEP (FIIP) by region, sex-at-birth, arm and cohort and used multivariable analysis to identify FIIP determinants. Baseline injectable PrEP preferences were higher in non-U.S. sites and increased in both regions over time. In multivariable models, FIIP was most strongly associated with acceptability of product attributes, was higher in non-U.S. sites and more altruistic participants. Treatment arm and report of pain were not associated with FIIP. Injectable acceptability was highest in non-U.S. sites. Preferences for injectable versus other PrEP methods were higher among U.S. males than females, but higher among males and females in non-U.S. settings.BACKGROUND To fulfil good manufacturing requirements, analytical methods for the analysis of pharmaceuticals for human and vetinary use must be validated. The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) has published guidance documents on the requirements for such validation activities and these have been adopted by the European Medicines Agency, The U.S. Food and Drug Administration (FDA) and other regulatory bodies. These guidance documents do not, however, fully address all the specific tests required for the analysis of radiopharmaceuticals. This guideline attempts to rectify this shortcoming, by recommending approaches to validate such methods. buy Galunisertib RESULTS Recommedations for the validation of analytical methods which are specific for radiopharmaceutials are presented in this guideline, along with two practical examples. CONCLUSIONS In order to comply with good manufacturing practice, analytical methods for radiopharmaceuticals for human use should be validated.Spatial abilities contribute to life and occupational competencies, and certain spatial skills differ, on average, between males and females, typically favoring males when differences occur. Factors contributing to spatial skills could include prenatal as well as experiential/cultural influences, with biological and social influences likely interacting and difficult to disentangle. This meta-analysis examined the potential influence of prenatal androgen exposure on spatial skill by examining studies of patients with congenital adrenal hyperplasia (CAH). CAH involves elevated adrenal androgens prenatally, with overall androgen concentrations higher for females with CAH versus same-sex controls but with little overall difference between males with CAH versus controls. We hypothesized that, if androgens contribute prenatally to neurobehavioral development in humans as in many other species, females with CAH would show spatial enhancement versus control females, but with no definitive hypothesis for males. Meta-analysis of 12 studies examining overall spatial skill and three spatial subcategories failed to support enhanced spatial performance for females with CAH; males with CAH showed lower spatial ability compared to control males, at least for the category of overall spatial skill. Although statistical logic precludes accepting the null hypothesis for females, the meta-analysis failed to support the idea that prenatal exposure to androgens explains spatial gender/sex differences in humans. Alternative explanations for average gender/sex differences in some spatial tasks could include androgen exposure at other times, such as mini-puberty, or different social factors experienced by males and females. We also discuss possible explanations for the different outcomes seen in females versus males with CAH.BACKGROUND Gastrodia elata is a fully mycoheterotrophic orchid and has long been used in traditional Chinese medicine. The life cycle of G. elata requires an association with two different fungi-Mycena for seed germination and Armillaria for tuber growth. The association with Armillaria is representative of the phytophagous type of orchid mycorrhiza the intracellular hyphae are lysed without forming condensed pelotons. However, whether the association with Mycena during seed germination belongs to the same type of orchid mycorrhiza is unknown. RESULTS Histological and ultrastructural studies revealed several notable features in different developmental stages. First, a thickened cell wall with papillae-like structures appeared during fungal penetration in the suspensor end cell, epidermal cells and cortical cells of germinating embryos. In addition, the formation of two distinctive cell types in the colonized region of a protocorm (i.e., the passage canal cell filled with actively growing fungal hyphae) can be observed in the epidermal cell, and the distinctive digestion cell with a dense cytoplasm appears in the cortex. Finally, within the digestion cell, numerous electron-dense tubules form a radial system and attach to degrading fungal hyphae. The fungal hyphae appear to be digested through endocytosis. CONCLUSIONS The present study provides important structural evidence for the phytophagous type of orchid mycorrhiza in the symbiotic germination of G. elata with Mycena. This case demonstrates a particular nutrient transfer network between G. elata and its litter-decaying fungal partner.The fruit fly's natural visual environment is often characterized by light intensities ranging across several orders of magnitude and by rapidly varying contrast across space and time. Fruit fly photoreceptors robustly transduce and, in conjunction with amacrine cells, process visual scenes and provide the resulting signal to downstream targets. Here, we model the first step of visual processing in the photoreceptor-amacrine cell layer. We propose a novel divisive normalization processor (DNP) for modeling the computation taking place in the photoreceptor-amacrine cell layer. The DNP explicitly models the photoreceptor feedforward and temporal feedback processing paths and the spatio-temporal feedback path of the amacrine cells. We then formally characterize the contrast gain control of the DNP and provide sparse identification algorithms that can efficiently identify each the feedforward and feedback DNP components. The algorithms presented here are the first demonstration of tractable and robust identification of the components of a divisive normalization processor.
