Chiral recognition of amino acids is very important in both chemical and life sciences. Although chiral recognition with luminescence has many advantages such as being inexpensive, it is usually slow and lacks generality as the recognition module relies on structural complementarity. Here, we show that one single molecular-solid sensor, L-phenylalanine derived benzamide, can manifest the structural difference between the natural, left-handed amino acid and its right-handed counterpart via the difference of room-temperature phosphorescence (RTP) irrespective of the specific chemical structure.

Vanillin, one of lignin-derived aromatics, can be used to synthesize vanillylamine that is a key fine chemical and pharmaceutical intermediate. To produce vanillylamine, a productive whole-cell-catalyzed biotransformation of vanillin was developed in deep eutectic solvent - surfactant - HO media.

Here, we aimed to investigate expression and function of NKD inhibitor of Wnt signaling pathway 1 (NKD1), an antagonist of Wnt-beta-catenin signaling pathways, in glioblastoma.
Methods: The mRNA level of NKD1 was firstly retrieved from TCGA glioma dataset to evaluate its correlation with clinical characteristics and its value in prognosis prediction.
Purpose: To assess the clinical efficiency of a novel ophthalmic viscosurgical device-free (OVD-free) method for intraocular collamer lens (EVO-ICL) implantation in myopic eyes.
Methods: In this study, 40 patients underwent ICL implantation for both eyes: one eye underwent traditional ICL implantation, and the other eye underwent OVD-free (pure) ICL implantation. Preoperative and postoperative UDVA, BCVA, equivalent spherical degree (SE), IOP, visual quality index, subjective visual quality scale, corneal endothelial cell density (ECD), operation time, and complications were compared between and within the traditional and pure ICL implantation groups.

Hypertension is a common cardiovascular disease in clinical scenario. The level of leptin changes with the development of hypertension and is regulated by Aldehyde dehydrogenase2 (ALDH2). Our study explored the relationship between irbesartan treatment and ALDH2.

A total of 86 patients with stage II to III essential hypertension were randomly divided into 4 groups: taking indapamide and losartan potassium together in the morning or in the evening 2 to 4 hours before sleep, indapamide in the morning and losartan potassium in the evening, losartan potassium in the morning and indapamide in the evening. Ambulatory blood pressure monitoring was performed before and 12 weeks after the medication.

HLECs-B3 were incubated in the fresh media containing sodium salicylate at different concentrations for different durations, and allowed to be recovered in fresh medium without sodium salicylate for different durations with or without pretreatment with p38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor (SP600125). The expression of P38MAPK, ERK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 was detected by Western blot.

The biosorption characteristics of Ni2+ by the waste biomass of Saccharomyces cerevisia were investigated, including the biosorption kinetics as well as equilibrium isotherm study. The experimental results showed that when the initial Ni2+ concentration was 65.6 mg/L, the process of Ni2+ biosorption onto the biomass of Saccharomyces cerevisia could be divided into two stages, the first stage was physical sorption and reached equilibrium very quickly (within 10 minutes).

The effect of the initial pH value on the biosorption behavior of 4-CP onto anaerobic granular sludge was investigated in this paper. The experimental results indicated that the initial pH value was the important parameter affecting the biosorption of 4-CP, and the biosorption capacity of anaerobic granular sludge decreased with the increase of pH value. The biosorption capacity of 4-CP was 6.

Sorption isotherms of 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) at various temperatures were determined; the data of 4-CP could be simulated by Langmuir model, while the data of 2,4-DCP could only be reproduced by Freudlich equation. The uptake capacity of 4-CP and 2,4-DCP could reach 1.
