Non-invasive assessment of gastric secretory function in centenarians

Geriatric Care, 2017
Gastric acid secretion is believed to decrease in the aging stomach, but the number of elderly patients on proton pump inhibitor (PPI) therapy is increasing.

BLOC: Buildable and Linkable Organ on a Chip

Advanced Materials Technologies, EarlyView.
We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...

Effects of supplemental hydrochloric acid and sodium bicarbonate on gastric acid secretion, digestive enzyme activities, intestinal microflora of early weaned piglets

浙江大学学报. 农业与生命科学版, 2005
Thirty crossbred weanling piglets with an average initial weight of 5.25 kg, weaned at (28±1) d of age, were divided into five groups to determine the effect of hydrochloric acid (HCl) and sodium bicarbonate (NaHCO3) supplementation on gastric acid ...

Gastric acid secretion after chemical sympathectomy

Gastroenterology, 1978
Adrenergic nerve terminals in several organs are selectively destroyed by 6-hydroxydopamine (6-OHDA) resulting in a chemical sympathectomy that is reversible. In this study the acute and chronic effects of 6-OHDA on gastric mucosa and acid secretion were evaluated. Four dogs were given 6-OHDA (40 mg/kg, intravenously).

Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

Advanced Science, EarlyView.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

Advanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Nitric oxide-an endogenous inhibitor of gastric acid secretion in isolated human gastric glands

BMC Gastroenterology, 2004
Background Endothelial nitric oxide synthase (eNOS) has previously been detected in the glandular part of the human gastric mucosa. Furthermore, nitric oxide (NO) has been shown to influence gastric secretion in various animal models.

Microenvironment Self‐Adaptive Nanoarmor to Address Adhesion‐ and Colonization‐Related Obstacles in Impaired Intestine Promote Bacteriotherapy Against Parkinson's Disease

Advanced Science, EarlyView.
A microenvironment self‐adaptive nanoarmor is developed to effectively address the adhesion‐ and colonization‐related challenges posed by multiple physiological and pathological characteristics in the intestine. L. plantarum@MPN@CS showed significant therapeutic potential in treating Parkinson's disease (PD), a model for extraintestinal disorders, as ...
