Amoxicillin-associated hemorrhagic colitis: A case report and literature review.

Rationale: Antibiotic-associated hemorrhagic colitis (AAHC) is a special type of antibiotic-associated colitis. Due to the increased use of antibiotics, especially amoxicillin, which is commonly used in clinical practice, the incidence of antibiotic-associated hemorrhagic colitis has also increased. However, doctors have insufficient understanding of this disease, and patients may be missed or misdiagnosed.

Power equipment supplier evaluation under a q-rung orthopair fuzzy set based decision making model.

The quality performance of power equipment suppliers is directly related to the stable and safe operation of the grid. This study presents a decision-making model based on q-rung orthopair fuzzy sets (q-ROFS) to evaluate suppliers, focusing on quality as the key criterion. To assess the objectivity and comprehensiveness of the results, we provide an innovative information fusion method that integrates the four dimensions of supply risk, supplier quality capability, profit impact, and willingness into the decision-making process.

Building hydrophobic substrate pocket to boost activity of laccase-like nanozyme through acetonitrile-mediated strategy.

Nanozymes, as promising alternatives to natural enzymes, offer several advantages with biocatalytic functions but remain inferior in catalytic activity. It is crucial to focus on factors that affect the enzymatic activity of nanozymes and develop strategies to make them more competitive with natural enzymes. Herein, CuVO nanorods are confirmed to own the intrinsic laccase-like activity, and an acetonitrile (MeCN)-mediated strategy is proposed for reaction acceleration by mimicking the enzymatic substrate pocket.

Experimental and simulation study on compressive failure of rock with pre-Y-shaped cracks.

A large number of joints and fissures are prevalent in the rock mass, which has an important influence on the mechanical properties of the rock mass. To study the failure mechanical characteristics of Y-cracked rocks, the paper analyzes the influence of different angles of prefabricated Y-cracked rocks on the mechanical strength characteristics of the rocks and the crack extension evolution through uniaxial compression indoor tests and discrete element PFC2D numerical simulation. The results indicate that the stress-strain curves of rocks containing prefabricated cracks exhibit five stages: the initial pore-fracture compaction stage, the elastic stage, the crack stable development stage, the crack unstable development stage, and the post-peak rupture.

Theoretical analysis and application of immobilized methanotrophs as typical adsorbent materials for adsorption/degradation of trichloroethylene.

Trichloroethylene (TCE) contamination presents a significant environmental challenge, necessitating efficient treatment solutions. This study aimed to develop an optimized immobilized bioreactor using methanotrophs for TCE degradation. Activated carbon fibres were identified as the optimal immobilization material, with an adsorption rate of 6-23 h - significantly faster than over 50 h for other materials - and the highest methane oxidation capacity of 0.

DYRK1A interacts with the tuberous sclerosis complex and promotes mTORC1 activity.

DYRK1A, a ubiquitously expressed kinase is linked to the dominant intellectual developmental disorder, microcephaly, and Down syndrome in humans. It regulates numerous cellular processes such as cell cycle, vesicle trafficking, and microtubule assembly. DYRK1A is a critical regulator of organ growth; however, how it regulates organ growth is not fully understood.

Sulfate-mediated Fe(III) mineral reduction accelerates arsenic mobilization by a Desulfovibrio strain isolated from paddy soil.

The biogeochemical cycling of arsenic (As) is often intertwined with iron (Fe) and sulfur (S) cycles, wherein Fe(III)- and sulfate-reducing bacteria (SRB) play a crucial role. Here, we isolated strain DS-1, a strictly anaerobic Fe(III)- and sulfate-reducing bacterium, from As-contaminated paddy soil. Using 16S rRNA gene sequence analysis, strain DS-1 was identified as a member of the genus Desulfovibrio.

Bifunctionally Electrocatalytic Bromine Redox Reaction by Single-Atom Catalysts for High-Performance Zinc Batteries.

Aqueous zinc-bromine (Zn||Br) batteries are regarded as one of the most promising energy storage devices due to their high safety, theoretical energy density, and low cost. However, the sluggish bromine redox kinetics and the formation of a soluble tribromide (Br ) hinder their practical applications. Here, it is proposed dispersed single iron atom coordinated with nitrogen atoms (FeN) in a mesoporous carbon framework (FeSAC-CMK) as a conductive catalytic bromine host, which possesses porous structure and electrocatalytic functionality of FeN species for enhanced confinement and electrocatalytic effect.

Clinical efficacy of dienogest against endometriomas with a maximum diameter of ≥4 cm.

Objective: This prospective observational study aims to demonstrate the clinical efficacy of dienogest in treating endometriomas with a maximum diameter of ≥4 cm.

Methods: Patients ( = 81) with endometriomas (diameter of ≥4 cm) were enrolled and administered orally with dienogest (2 mg daily) and followed up for a year [Ethical approval code: 2020 Research 343]. Further, the efficacy was determined by recording the largest diameter and volume of the endometriomas, uterine volume, endometrial thickness, and the largest diameter of uterine fibroids in the patients during 0, 6, and 12 months.

Spatiotemporal Analysis of Mesenchymal Stem Cells Fate Determination by Inflammatory Niche Following Soft Tissue Injury at a Single-Cell Level.

Heterotopic ossification (HO), often arising in response to traumatic challenges, results from the aberrant osteochondral differentiation of mesenchymal stem cells (MSCs). Nevertheless, the impact of trauma-induced inflammatory exposure on MSC fate determination remains ambiguous. In this study, the cellular diversity within inflammatory lesions is elucidated, comprising MSCs and several innate and adaptive immune cells.

Target Fishing Reveals a Novel Mechanism of -Acylamino Saccharin Derivatives Targeting Glyceraldehyde-3-Phosphate Dehydrogenase toward Cyanobacterial Blooms Control.

Based on current challenges of poor targeting and limited choices in chemical control methods of cyanobacterial blooms (CBs), identifying new targets is an urgent and formidable task in the quest for target-based algaecides. This study discovered -acylamino saccharin derivatives exhibiting potent algicidal activity. Thus, using -acylamino saccharin as the probes, glyceraldehyde-3-phosphate dehydrogenase from cyanobacterial (GAPDH) was identified as a new target of algaecides through the activity-based protein profiling (ABPP) strategy for the first time.

LINC00461 promotes bladder cancer cells EMT through miR-518b/HNRNPUL1 axis.

Bladder cancer (BC) is a prevalent type of tumor in the urinary system, and it has been discovered that long non-coding RNA (lncRNA) plays a significant role in its occurrence and development. However, thus far, no reports have been published on the involvement of LINC00461 in BC. Here, we found that LINC00461 levels were upregulated in BC tissues and cell lines.

Ginsenoside Rg3 Restores Mitochondrial Cardiolipin Homeostasis via GRB2 to Prevent Parkinson's Disease.

Regulating cardiolipin to maintain mitochondrial homeostasis is a promising strategy for addressing Parkinson's disease (PD). Through a comprehensive screening and validation process involving multiple models, ginsenoside Rg3 (Rg3) as a compound capable of enhancing cardiolipin levels is identified. This augmentation in cardiolipin levels fosters mitochondrial homeostasis by bolstering mitochondrial unfolded protein response, promoting mitophagy, and enhancing mitochondrial oxidative phosphorylation.
