Study Question: Does a human fallopian tube (HFT) organoid model offer a favourable apical environment for human sperm survival and motility?
Summary Answer: After differentiation, the apical compartment of a new HFT organoid model provides a favourable environment for sperm motility, which is better than commercial media.
What Is Known Already: HFTs are the site of major events that are crucial for achieving an ongoing pregnancy, such as gamete survival and competence, fertilization steps, and preimplantation embryo development. In order to better understand the tubal physiology and tubal factors involved in these reproductive functions, and to improve still suboptimal in vitro conditions for gamete preparation and embryo culture during IVF, we sought to develop an HFT organoid model from isolated adult stem cells to allow spermatozoa co-culture in the apical compartment.
Being honest won't pay. Seven- but not 5-year-olds begin to predict that others will lie for reputational reasons.

Children begin to manage their reputation around school-age, but it remains unclear when they start to explicitly reason about reputational strategies such as lying from a third-person perspective. The current study investigated whether 5- and 7-year-old children would explicitly predict reputational lying in the context of a third party interaction. Participants were told hypothetical stories and asked to predict whether a protagonist would lie to a peer character about a selfish resource allocation.

Visible-light absorbing metal-free organic dyes are of increasing demand for various optoelectronic applications because of their great structure-function tunability through chemical means. Several dyes also show huge potential in triplet photosensitization, generating reactive singlet oxygen. Understanding the structure-property relationships of many well-known fluorescein dyes is of paramount importance in designing next-generation energy efficient dyes, which is currently limited.

Background: Discrete choice experiments (DCEs) are increasingly used to inform the design of health products and services. It is essential to understand the extent to which DCEs provide reliable predictions outside of experimental settings in real-world decision-making situations. We aimed to compare the prediction accuracy of stated preferences with real-world choices, as modelled from DCE data.

We conducted this study to understand the future plans of medical students and their perceptions regarding their medical education and healthcare system.
Method: We performed this cross-sectional study at five public and private Sudanese medical schools in November 2023.
