Bufalin induces apoptosis and autophagy via the Ca2+/CaMKKβ/AMPK/Beclin1 signaling pathway in osteosarcoma cells.

Bufalin, a major cardiotonic compound of the traditional Chinese medicine Chanshu has been used for cancer treatment for several years. However, the molecular mechanisms of Bufalin-induced autophagy in osteosarcoma (OS) is not fully understood. In the present study, it was shown that Bufalin induced crosstalk between apoptosis and autophagy, which resulted in OS cell death.

The Effects of Different Doses of Alfentanil and Dexmedetomidine on Prevention of Emergence Agitation in Pediatric Tonsillectomy and Adenoidectomy Surgery.

Emergence agitation (EA) is a common problem often observed in children after sevoflurane anesthesia, which can be prevented by dexmedetomidine and alfentanil. This study aims to compare the effectiveness of dexmedetomidine alone and with different doses of alfentanil in preventing EA in children under sevoflurane anesthesia. In a double-blind trial, 80 children (ASA I or II, 3-7 years old) undergoing tonsillectomy alone and adenotonsillectomy with sevoflurane anesthesia were randomly assigned into four groups: the control group, dexmedetomidine (DEX) group, dexmedetomidine plus 10 μg/kg alfentanil group (DEX + Alf1), and dexmedetomidine plus 20 μg/kg alfentanil group (DEX + ALf2).

Association of the and gene polymorphisms with COPD risk: a meta-analysis.

Introduction: Given the evidence that the matrix metalloproteinases (MMPs) play an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD), a number of case-control studies have attempted to assess the relationship between genetic polymorphisms in genes and COPD risk. However, reliable measures of these results are lacking.

Material And Methods: We assessed the published evidence for association of the -9 and polymorphisms with COPD risk using meta-analytic techniques.

Nebulization in the Treatment of COVID-19: A Randomized, Double-Blind, Placebo-Controlled Trial.

In this randomized, double-blind, placebo-controlled clinical trial, we included 31 adult patients with moderate COVID-19 who were admitted to the Fourth People's Hospital of Nanning (Nanning, China) between January 22, 2020 and February 17, 2020.

The copper(II) complexes of new anthrahydrazone ligands: In vitro and in vivo antitumor activity and structure-activity relationship.

Two new copper(II) complexes, 9-PMAH-Cu (1) and 9-FPMAH-Cu (2), of anthrahydrazone were synthesized and structurally characterized, in which 9-FPMAH (9-(4'-trifluoromethyl)-pyrimidine anthrahydrazone) is the 4'-CF derivative of 9-PMAH (9-pyrimidine anthrahydrazone). Both complexes 1 and 2 showed similar intercalative binding modes towards DNA and might compete with the typical DNA intercalator, GelRed, in the same binding site. They could also act as topoisomerase (type I) suppressor to effectively inhibit its activity, in which complex 1 was more effective than 2.

Effect of Intravenous Glucose Tolerance Test on Bone Turnover Markers in Adults with Normal Glucose Tolerance.

BACKGROUND It is well known that enteral nutrients result in acute suppression of bone turnover markers (BTMs), and incretin hormones are believed to play a significant role in this physiological skeletal response. However, there is limited research exploring the impact of parenteral nutrients on BTMs. Our aim was to assess the influence of intravenous glucose on BTMs in adults with normal glucose tolerance (NGT).

Effect of BIX-01294 on H3K9me2 levels and the imprinted gene Snrpn in mouse embryonic fibroblast cells.

Histone H3 lysine 9 dimethylation (H3K9me2) hypermethylation is thought to be a major influential factor in cellular reprogramming, such as somatic cell nuclear transfer (SCNT) and induction of pluripotent stem cells (iPSCs). The diazepin-quinazolin-amine derivative (BIX-01294) specifically inhibits the activity of histone methyltransferase EHMT2 (euchromatic histone-lysine N-methyltransferase 2) and reduces H3K9me2 levels in cells. The imprinted gene small nuclear ribonucleoprotein N (Snrpn) is of particular interest because of its important biological functions.
