Inhibition of by submerged macrophytes and epiphytic biofilms.

To investigate the potential role of epiphytic biofilms in the inhibition of submerged macrophytes on , we compared the effect of crude extracts from on the growth and photosynthesis pigments of under conditions of retaining and removing biofilms. The results showed that there was a significant enhancement in inhibitory effects of plant extracts against when retaining epiphytic biofilms. By the end of the experiment, the inhibition rate reached up to 85.

Short-term usage of proton pump inhibitors during admission was associated with increased risk of rehospitalization in critically ill patients with myocardial infarction: a cohort study.

Purpose: Previous studies showed that long-term use of proton pump inhibitors (PPIs) was associated with cardiovascular events. However, the impact of short-term PPI exposure on intensive care unit (ICU) patients with myocardial infarction (MI) remains largely unknown. This study aims to determine the precise correlation between short-term PPI usage during hospitalization and prognostic outcomes of ICU-admitted MI patients using Medical Information Mart for Intensive Care IV database (MIMIC-IV).

Application of urinary N-acetyl-β-D-glucosaminidase combined with serum retinol-binding protein in early detection of diabetic nephropathy.

Background: Diabetic nephropathy (DN) is a microangiopathy of type 2 diabetes mellitus (T2DM), which can damage the kidney through various ways and mechanisms due to the nature of the disease, involving the renal interstitium and glomeruli. However, in the early stage of the disease, patients only showed kidney volume increase and glomerular hyperthyroidism, and typical symptoms that are difficult to arouse individual attention were noticed.

Aim: To observe the expression of serum retinol-binding protein (RBP) and urinary N-acetyl-β-D-glucosaminidase (NAG) in patients with DN, and to analyze their value in disease prediction, so as to provide new targets for early diagnosis and treatment of DN.

MiR-125 family improves the radiosensitivity of head and neck squamous cell carcinoma.

Background: MiRNAs can affect the radiosensitization of head and neck squamous cell carcinoma (HNSCC). We aimed to analyze the function of miR-125 family members in HNSCC using The Cancer Genome Atlas (TCGA) and determine their effect on radiation in laryngeal squamous cell cancer (LSCC).

Methods: First, we systematically analyzed the role of the miR-125 family in HNSCC using the TCGA database and found that miR-125a-5p is associated with radiotherapy.

Cholesterol gallstones: Focusing on the role of interstitial Cajal-like cells.

Cholesterol gallstone (CG) is a common, frequent biliary system disease in China, with a complex and multifactorial etiology. Declined gallbladder motility reportedly contributes to CG pathogenesis. Furthermore, interstitial Cajal-like cells (ICLCs) are reportedly present in human and guinea pig gallbladder tissue.

Liver injury in COVID-19: A minireview.

In December 2019, an outbreak of unexplained pneumonia was reported in Wuhan, China. The World Health Organization officially named this disease as novel coronavirus disease 2019 (COVID-19). Liver injury was observed in patients with COVID-19, and its severity varied depending on disease severity, geographical area, and patient age.

Transition-Metal-Free Aryl-Heteroatom Bond Formation via C-S Bond Cleavage.

Aryl-heteroatom bonds (C-Het) are almost ubiquitously present in chemical molecules. However, methods for diverse C-Het bond formations from a simple substrate are limited. Herein, we report a convenient and efficient C-S bond transformation of aryl sulfoniums to various C-Het bonds (C-O, C-S, C-Sn, C-Si, C-Se) in the absence of any transition-metal catalyst.

Non-transition Metal-Mediated Diverse Aryl-Heteroatom Bond Formation of Arylammonium Salts.

Aryl-heteroatom (C-X) bonds ubiquitously exist in organic, medicinal, and material chemistry, but a universal method to construct diverse C-X bonds is lacking. Here we report our discovery of a convenient and efficient approach to construct various C-X bonds using arylammonium salts as the substrate via an SAr process. This strategy features mild reaction condition, no request of transition metal catalyst, and easy formation of various C-X bonds (C-S, C-Si, C-Sn, C-Ge, C-Se, C-N).
