Recyclable covalent organic frameworks/cellulose aerogels for efficient uranium adsorption.

The advancement of efficient, recyclable adsorbents for the economical capture of uranium from seawater is critical for the sustainable progression of nuclear energy. In this work, a unique aerogel composed of covalent organic frameworks (COF-TpTHA)/cellulose nanofibrils (CNF) was synthesized under mild conditions for uranium adsorption. TpTHA/CNF aerogel resolves challenges related to the formability of COF.

Left-versus-right-adrenal-volume ratio as a screening index before adrenal venous sampling to identify unilateral primary aldosteronism patients.

Objectives: The current study aimed to investigate the value of the computed tomography-based left-versus-right adrenal gland volume ratio (L/Rv) in screening patients with unilateral primary aldosteronism.

Methods: The current study recruited 114 patients who underwent successful adrenal venous sampling (AVS) and adrenal computed tomography at West China Hospital of Sichuan University. The patients were divided into three groups according to the AVS results: AVS-left, AVS-bilateral, and AVS-right primary aldosteronism.

Identification of bitter compounds in whole wheat bread crumb.

Consumer acceptability of whole wheat foods is challenged by negative bitter flavour attributes. In this study, bitter compounds in whole wheat bread crumb were investigated. Utilising sensory-guided multi-dimensional fractionation techniques, the compounds with the highest bitterness intensity in the crumb were purified and identified by LC-MS-ToF and NMR techniques.

Influence of endogenous ferulic acid in whole wheat flour on bread crust aroma.

The influence of wheat flour type (refined (RWF)/whole (WWF)) on bread crust aroma was investigated. Differences were characterized by aroma extract dilution analysis and quantified utilizing stable isotope surrogate standards. For RWF breads, five aroma compounds were higher in concentration, 2-acetyl-1-pyrroline, 4-hydroxy-2,5-dimethyl-3(2H)-furanone, 2-phenylethanol, 2-acetyl-2-thiazoline, and 2,4-dihyroxy-2,5-dimethyl-3(2H)-furanone, by 4.

Epidemiology of maxillofacial injury in children under 15 years of age in southern China.

Objective: This retrospective study was conducted to report the epidemiology of maxillofacial injuries of children <15 years old in China.

Study Design: Data collected in this study included age, sex, etiology, date of injury, anatomic site of injury, and treatment modality. Regarding treatment, conservative technique and surgery were both used.

Influence of phenolic compounds on the mechanisms of pyrazinium radical generation in the Maillard reaction.

The generation of pyrazinium radical cations during the early stages of the Maillard reaction has been previously demonstrated. In this study, the effect of food phenolic compounds [4-methylcatechol (4-MeC), (+)-catechin (CAT), and (-)-epigallocatechin-3-gallate (EGCG)] on the fate of these intermediates in Maillard model systems was investigated. Aqueous solutions containing either glyoxal + alanine (GO-A) or glycolaldehyde + alanine (GA-A) were treated with a concentration gradient of each phenolic compound, and quantitative analysis of the resulting pyrazinium radicals in these models was performed using electron paramagnetic resonance (EPR) spectroscopy.

Follow-up study of a pregnant woman 16 years after exposure in the Xinzhou radiation accident.

To investigate the late effects of radiation on child-bearing women, a follow-up study was performed on a 39-year-old survivor 16 years after a (60)Co radiation accident. The woman, Fang, was 19 weeks pregnant at the time of exposure. Physical examinations, a full range of clinical laboratory and imaging tests, as well as cytogenetic analyses were conducted to evaluate Fang's current health conditions.

Immune clearance gastric carcinoma cells in ascites by activating caspase-9-induced apoptosis.

Floating gastric adenocarcinoma cells in ascitic fluid are the main cause of peritoneal dissemination. Activation of apoptosis is an important mechanism by which tumor cells are eliminated by the immune surveillance system. Hence, we examined caspase-9 expression and the apoptosis in gastric adenocarcinoma cells in ascitic fluid using immunohistochemistry, real-time polymerase chain reaction and in situ cell death detection kits, flow cytometry.
