[Removal Performance and Mechanism of Potassium Permanganate Modified Coconut Shell Biochar for Cd(Ⅱ) and Ni(Ⅱ) in Aquatic Environment].

In this study, coconut shell biochar modified by KMnO (MCBC) was used as the adsorbent, and its removal performance and mechanism for Cd(Ⅱ) and Ni(Ⅱ) were discussed. When the initial pH and MCBC dosage were separately 5 and 3.0 g·L, respectively, the removal efficiencies of Cd(Ⅱ) and Ni(Ⅱ) were both higher than 99%.

Novel gene mutation in maturity-onset diabetes of the young: A case report.

Background: Maturity-onset diabetes of the young (MODY) is the most common monogenic type of diabetes. Recently, 14 gene mutations have been found to be associated with MODY. In addition, the gene mutation is the pathogenic gene of MODY7.

P2X7 Receptor in Alcoholic Steatohepatitis and Alcoholic Liver Fibrosis.

Alcoholic liver disease is one of the most common chronic liver diseases in the world. It is a liver disease caused by prolonged heavy drinking and its main clinical features are nausea, vomiting, enlargement of the liver, and jaundice. Recent studies suggest that Kupffer cell-mediated inflammatory response is a core driver in the development of alcoholic steatohepatitis and alcoholic liver fibrosis.

Real microgravity condition promoted regeneration capacity of induced pluripotent stem cells during the TZ-1 space mission.

Induced pluripotent stem cells (iPSCs) are reprogrammed somatic cells that gained self-renewal and differentiation capacity similar to embryonic stem cells. Taking the precious opportunity of the TianZhou-1 spacecraft mission, we studied the effect of space microgravity (µg) on the self-renewal capacity of iPSCs. Murine iPSCs carrying pluripotency reporter Oct4-GFP were used.

Tetrahydroquinoline and tetrahydroisoquinoline derivatives as potential selective PDE4B inhibitors.

Tetrahydroquinoline and tetrahydroisoquinoline derivatives containing 2-phenyl-5-furan moiety were designed and synthesized as phosphodiesterase type 4 (PDE4) inhibitors. The bioassay results showed that title compounds showed good inhibitory activity against PDE4B and blockade of LPS (lipopolysaccharide) induced TNF-α release, which also exhibited considerable in vivo activity in animal models of asthma/COPD (chronic obstructive pulmonary disease) and sepsis induced by LPS. The bioactivity of compounds containing tetrahydroquinoline (series 4) was higher than that of tetrahydroisoquinoline derivatives (series 3).

Fluoroquinolone derivatives and their anti-tubercular activities.

Tuberculosis (TB) remains one of the most widespread and leading deadliest diseases, around one-third of the world's population harbor a latent infection by Mycobacterium tuberculosis (MTB), and 5-10% eventually develop an active TB. The emergency of MTB new virulent forms as well as the co-infection between MTB and HIV alarming the serious problem in TB control and demanding the need for new drugs more potent than earlier with safe ADME profile. Fluoroquinolones are emerged as a large family of synthetic broad spectrum antibiotics, and some of them were recommended as the second-line agents for the treatment of TB mainly in cases involving resistance or intolerance to first-line anti-TB therapy by WHO.

Antiplasmodial and antimalarial activities of quinolone derivatives: An overview.

Malaria remains one of the most deadly infectious diseases globally. Considering the growing spread of resistance, development of new and effective antimalarials remains an urgent priority. Quinolones, which are emerged as one of the most important class of antibiotics in the treatment of various bacterial infections, showed potential in vitro antiplasmodial and in vivo antimalarial activities, making them promising candidates for the chemoprophylaxis and treatment of malaria.

Intramolecular etherification and polyene cyclization of π-activated alcohols promoted by hot water.

Hot water, acting as a mildly acidic catalyst, efficiently promoted intramolecular direct nucleophilic substitution reactions of unsaturated alcohols with heteroatom or carbon nucleophiles. In a mixed solvent of water and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), polyene cyclizations using allylic alcohols as initiators gave the desired cyclized products, and in neat HFIP, a tricyclization reaction gave a tetracyclic product in 51% chemical yield.

Supplementation of iron alone and combined with vitamins improves haematological status, erythrocyte membrane fluidity and oxidative stress in anaemic pregnant women.

Pregnancy is a condition exhibiting increased susceptibility to oxidative stress, and Fe plays a central role in generating harmful oxygen species. The objective of the present study is to investigate the changes in haematological status, oxidative stress and erythrocyte membrane fluidity in anaemic pregnant women after Fe supplementation with and without combined vitamins. The study was a 2 months double-blind, randomised trial.

Promoter hypermethylation correlates with the Hsulf-1 silencing in human breast and gastric cancer.

The HSulf-1 gene is an important factor that modulates the sulfation status of heparan sulfate proteoglycans (HSPGs) in the extracellular matrix, resulting in disturbance of HSPG-related signal transduction pathways. Recently, HSulf-1 has been reported to be down-regulated in several human cancers. In this study, we first cloned and characterized the 5' promoter region of the HSulf-1 gene (around 400 bp) that contained high basal promoter activity.
