Modulating the endogenous stores of gastrointestinal hormones is considered a promising strategy to mimic gut endocrine function, improving metabolic dysfunction. Here, we exploit mouse and human knock-in and knockout intestinal organoids and show that agents used as commercial lipid excipients can activate nutrient-sensitive receptors on enteroendocrine cells (EECs) and, when formulated as lipid nanocarriers, can bestow biological effects through the release of GLP-1, GIP, and PYY from K and L cells. Studies in wild-type, dysglycemic, and gut knockout mice demonstrated that the effect exerted by lipid nanocarriers could be modulated by varying the excipients (e.

The secondary aim included exploring demographics, obstetrics characteristics, and comorbidities among these women.
Methods: A retrospective comprehensive review of the records of 300 cases of pregnant women with COVID-19, who were treated between November 2020 and April 2021 at Queen Alia Military Hospital (a main referral center for patients with COVID-19) in Jordan.
Background: Combination immune checkpoint blockade targeting PD-1 and CTLA-4 leads to high response rates and improved survival in advanced cutaneous melanoma (CM). Less is known about the efficacy of this combination in acral lentiginous melanoma (ALM).
Objectives: To determine the efficacy of combination immune checkpoint blockade targeting PD-1 and CTLA-4 in a real-world, diverse population of ALM.
Background: Enteroendocrine cells (EECs) produce over 20 gut hormones which contribute to intestinal physiology, nutrient metabolism and the regulation of food intake. The objective of this study was to generate a comprehensive transcriptomic map of mouse EECs from the stomach to the rectum.
Methods: EECs were purified by flow-cytometry from the stomach, upper small intestine, lower small intestine, caecum and large intestine of NeuroD1-Cre mice, and analysed by single cell RNA sequencing.
Article Synopsis
- - Deuteration, the process of replacing hydrogen atoms with deuterium, impacts the oxidative stability of squalene, an important ingredient in cosmetics and vaccine adjuvants.
- - The study quantified how different levels of deuteration affect the formation of harmful peroxides that can clog pores (comedogenic peroxides).
- - Results showed that even a low level of deuteration (19%) significantly reduced the formation of these peroxides, indicating its potential benefits for product stability.
