Exploration and validation of a novel reactive oxygen species-related signature for predicting the prognosis and chemotherapy response of patients with bladder cancer.

Background: Reactive Oxygen Species (ROS), a hallmark of cancer, is related to prognosis, tumor progression, and treatment response. Nevertheless, the correlation of ROS-based molecular signature with clinical outcome and immune cell infiltration has not been thoroughly studied in bladder cancer (BLCA). Accordingly, we aimed to thoroughly examine the role and prognostic value of ROS-related genes in BLCA.

Long-term survival of a kidney transplant patient with advanced renal cancer after combination therapy: a case report and literature review.

renal transplant carcinoma, especially in the context of bilateral renal carcinoma, is rare and often presents as small, low-grade papillary renal cell carcinoma (RCC). There is currently no consensus or effective treatment for advanced metastatic RCC after kidney transplantation. A 40-year-old man developed renal transplant carcinoma with venous thrombus and lung metastases 13 years after transplantation.

Mycobacterium paragordonae pulmonary disease with rapidly growing solitary lesions: a case report and literature review.

Introduction: Mycobacterium paragordonae (MPG) is a novel and uncommon nontuberculous mycobacterium (NTM). We describe a case of MPG pulmonary disease (MPGPD) with a single, rapidly growing, pulmonary mass, which has rarely been reported.

Case Report: A chest CT scan of a 66-year-old woman revealed a rapidly growing solitary mass-like lesion in the upper lobe of the right lung, which was not seen in the previous chest CT scan six months ago.

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.

The Discovery of Novel α Adrenergic Receptor Agonists Only Coupling to Gαi/O Proteins by Virtual Screening.

Most α-AR agonists derived from dexmedetomidine have few structural differences between them and have no selectivity for α-AR or Gi/Gs, which can lead to side effects in drugs. To obtain novel and potent α-AR agonists, we performed virtual screening for human α-AR and α-AR to find α-AR agonists with higher selectivity. Compound P300-2342 and its three analogs significantly decreased the locomotor activity of mice ( < 0.

Designing Chromane Derivatives as α-Adrenoceptor Selective Agonists via Conformation Constraint.

Enhancing the selectivity of alpha-adrenoceptor (α-AR) agonists remains an unresolved issue. Herein, we reported the design of an α-AR agonist using the conformation constraint method, beginning with medetomidine. The structure-activity relationship indicated that the 8-substituent of chromane derivatives exerted the most pronounced effect on α-AR agonistic activity.

Protective efficacy of a universal influenza mRNA vaccine against the challenge of H1 and H5 influenza A viruses in mice.

Current influenza vaccines need to be updated annually owing to constant antigenic drift in the globular head of the viral surface hemagglutinin (HA) glycoprotein. The immunogenic subdominant stem domain of HA is highly conserved and can be recognized by antibodies capable of binding multiple HA subtypes. Therefore, the HA stem antigen is a promising target for the design of universal influenza vaccines.

A self-supported porous NiMo electrocatalyst to boost the catalytic activity in the hydrogen evolution reaction.

To develop hydrogen energy production and address the issues of global warming, inexpensive, effective, and long-lasting transition metal-based electrocatalysts for the synthesis of hydrogen are crucial. Herein, a porous electrocatalyst NiMo/Ni/NF was successfully constructed by a two-step electrodeposition process, and was used in the hydrogen evolution reaction (HER) of electrocatalytic water decomposition. NiMo nanoparticles were coated on porous Ni/NF grown on nickel foam (NF), leading to a resilient porous structure with enhanced conductivity for efficient charge transfer, as well as distinctive three-dimensional channels for quick electrolyte diffusion and gas release.

Therapeutic stapled peptides: Efficacy and molecular targets.

Peptide stapling, by employing a stable, preformed alpha-helical conformation, results in the production of peptides with improved membrane permeability and enhanced proteolytic stability, compared to the original peptides, and provides an effective solution to accelerate the rapid development of peptide drugs. Various reviews present peptide stapling chemistries, anchoring residues and one- or two-component cyclization, however, therapeutic stapled peptides have not been systematically summarized, especially focusing on various disease-related targets. This review highlights the latest advances in therapeutic peptide drug development facilitated by the application of stapling technology, including different stapling techniques, synthetic accessibility, applicability to biological targets, potential for solving biological problems, as well as the current status of development.

Robust and flexible polyester fiber membrane with under-liquid dual superlyophobicity for efficient on-demand oil-water separation.

Functional materials with under-liquid dual superlyophobicity have generated a great deal of concern from researchers due to their switchable separation ability oil-water mixtures and emulsions. Conceptually, under-liquid dual superlyophobicity is a Cassie state achievable under-liquid through the synergy of an under-liquid double lyophobic surface and the construction of a highly rough surface. However, obtaining an under-liquid dual superlyophobic surface remains difficult due to its thermodynamic contradiction and complex surface composition.

All-hydrocarbon stapling enables improvement of antimicrobial activity and proteolytic stability of peptide Figainin 2.

Figainin 2 is a cationic, hydrophobic, α-helical host-defense peptide with 28 residues, which was isolated from the skin secretions of the Chaco tree frog. It shows potent inhibitory activity against both Gram-negative and Gram-positive pathogens and has garnered considerable interest in developing novel classes of natural antibacterial agents. However, as a linear peptide, conformational flexibility and poor proteolytic stability hindered its development as antibacterial agent.

A New Phenothiazine-Based Fluorescent Sensor for Detection of Cyanide.

A new fluorescent sensor for the detection of CN was developed based on the conjugation of phenothiazine fluorophore and benzofuran unit. By the nucleophilic attacking of CN to the fluoroacetylamino group in the sensor, the additional reaction of CN and carbonyl group induced the ICT (intramolecular charge transfer) effect in the molecule and caused the fluorescence quenching sensor. The titration experiments show that the sensor has good sensitivity, selectivity and quick response for CN.
