Microwave-assisted synthesis of highly photoluminescent core/shell CuInZnSe/ZnS quantum dots as photovoltaic absorbers.

Water-dispersible core/shell CuInZnSe/ZnS (CIZSe/ZnS) quantum dots (QDs) were efficiently synthesized under microwave irradiation using -acetylcysteine (NAC) and sodium citrate as capping agents. The photoluminescence (PL) emission of CIZSe/ZnS QDs can be tuned from 593 to 733 nm with varying the Zn : Cu molar ratio in the CIZSe core. CIZSe/ZnS QDs prepared with a Zn : Cu ratio of 0.

Mapping the spatial transferability of knowledge-guided machine learning: Application to the prediction of drain flow fraction.

Machine learning (ML) methods continue to gain traction in hydrological sciences for predicting variables at large scales. Yet, the spatial transferability of these ML methods remains a critical yet underexamined aspect. We present a metamodel approach to obtain large-scale estimates of drain fraction at 10 m spatial resolution, using a ML algorithm (Gradient Boost Decision Tree).

More Anastomotic Ulcers, Less Dumping, and Equal Weight Loss in Long vs. Short Gastric Pouch in Laparoscopic Roux-en-Y Gastric Bypass.

Background: Anastomotic ulcers (AU) at the gastroenterostomy are a common postoperative complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). Possible risk factors for ulcer formation include active smoking, the use of non-steroidal anti-inflammatory drugs, increased tension or ischemia at the anastomosis, or factors that increase the acid secretion of the gastric pouch. Therefore, a longer gastric pouch may increase risk of AU formation after LRYGB.

Targeted deletion of the pancreatic β-cell oxytocin receptor and its effects on metabolic regulation and β-cell health.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) have been shown to play an important role in glucose metabolism, and pancreatic islets express this ligand and receptor. In the current study, OXTR expression was identified in α-, β-, and δ-cells of the pancreatic islet by RNA hybridization, and OXT protein expression was observed only in β-cells. In order to examine the contribution of islet OXT/OXTR in glycemic control and islet β-cell heath, we developed a β-cell specific OXTR knock-out (β-KO) mouse.

Macrophage-induced enteric neurodegeneration leads to motility impairment during gut inflammation.

Current studies pictured the enteric nervous system and macrophages as modulators of neuroimmune processes in the inflamed gut. Expanding this view, we investigated the impact of enteric neuron-macrophage interactions on postoperative trauma and subsequent motility disturbances, i.e.
