Comparing the photodegradation of typical antibiotics in ice and in water: Degradation kinetics, mechanisms, and effects of dissolved substances.

New antibiotic contaminants have been detected in both surface waters and natural ice across cold regions. However, few studies have revealed distinctions between their ice and aqueous photochemistry. In this study, the photodegradation and effects of the main dissolved substances on the photolytic kinetics were investigated for sulfonamides (SAs) and fluoroquinolones (FQs) in ice/water under simulated sunlight.

Cuproptosis-related gene SLC31A1: prognosis values and potential biological functions in cancer.

Cuproptosis is a unique type of cell death that may influence tumour formation by targeting lipoylated tricarboxylic acid cycle proteins. Solute carrier family 31 member 1 (SLC31A1), an important copper transporter, influences dietary copper absorption in the cell membrane. However, various SLC31A1 properties in pan-cancer profiles remain unknown.

Insight into typical photo-assisted AOPs for the degradation of antibiotic micropollutants: Mechanisms and research gaps.

Due to the incomplete elimination by traditional wastewater treatment, antibiotics are becoming emerging contaminants, which are proved to be ubiquitous and promote bacterial resistance in the aquatic systems. Antibiotic pollution has raised particular concerns, calling for improved methods to clean wastewater and water. Photo-assisted advanced oxidation processes (AOPs) have attracted increasing attention because of the fast reaction rate, high oxidation capacity and low selectivity to remove antibiotics from wastewater.

Peutz-Jeghers syndrome with gastric-type mucinous endocervical adenocarcinoma and sex-cord tumor with annular tubules: A case report.

Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant genetic disorder characterized by mucocutaneous pigmentation and multiple hamartomatous polyps in the gastrointestinal tracts. About 11% of female PJS patients are diagnosed with Gastric-type endocervical adenocarcinoma (G-EAC) and about one third have a sex-cord tumor with annular tubules (SCTATs). Gastric-type endocervical adenocarcinoma is a special subtype of cervical adenocarcinoma which accounts for only 1-3%.

2,4,6-Trimethyl-N-[1-(1H-pyrrol-2-yl)ethyl-idene]aniline.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(18)N(2), each of which features a syn disposition of the N atoms. In each mol-ecule, the pyrrole and benzene rings are essentially perpendicular, with dihedral angles of 78.90 (9) and 79.

N-[1-(1H-Pyrrol-2-yl)ethyl-idene]aniline.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2), in which the pyrrole and benzene rings form dihedral angles of 72.37 (7) and 82.34 (8)°.
