MALAT1-related signaling pathways in colorectal cancer.

Colorectal cancer (CRC) is one of the most lethal and prevalent solid malignancies worldwide. There is a great need of accelerating the development and diagnosis of CRC. Long noncoding RNAs (lncRNA) as transcribed RNA molecules play an important role in every level of gene expression.

P2X7 receptor involved in antitumor activity of atractylenolide I in human cervical cancer cells.

Atractylenolide I (Atr-I) was found to sensitize a variety of human cancer cells in previous studies. Purinergic P2X7R plays important role in different cancers. However, whether Atr-I could generate antitumor activity in human cervical cancer cells and P2X7R get involved in this effect remain unclear.

Does probiotics work for bacterial vaginosis and vulvovaginal candidiasis.

The different Lactobacillus strains of probiotics have been applied to the treatment and prevention of bacterial vaginosis and vulvovaginal candidiasis. The experimental data demonstrated that it works well via reducing the number of harmful bacteria, maintaining the acidic microenvironment, inhibiting the immune response, and so on, to restore the vaginal microecology. However, the clinical data indicated that it is not sufficient to support the use of probiotics in the intervention of vulvovaginal candidiasis rather than bacterial vaginosis.

Effect of a short-term vitamin E supplementation on oxidative stress in infertile PCOS women under ovulation induction: a retrospective cohort study.

Background: Vitamin E, which is critically important in the whole process of reproduction, can antagonize the oxidative stress caused by the oxygen free radicals and antioxidant imbalance and regulate normal physiological function of the reproductive system. The effect of short-term supplementation of vitamin E on outcomes of infertile women with polycystic ovary syndrome (PCOS) when they underwent ovulation induction with clomiphene citrate (CC) and human menopausal gonadotropin (HMG) remains unknown.

Methods: This was a retrospective cohort clinical trial from October 2015 to April 2017.

Tyrosine nitrations impaired intracellular trafficking of FSHR to the cell surface and FSH-induced Akt-FoxO3a signaling in human granulosa cells.

Many infertile women suffered from poor ovarian response, and increased reactive oxygen species with age might mediate the poor ovarian response to FSH. In this study, we collected follicular fluids and isolated granulosa cells from female patients. Increased levels of peroxynitrite, tyrosine nitrations of FSH receptor (FSHR) and apoptosis were obviously detectable with decreased FSHR protein expressions in granulosa cells of the poor ovarian responders.

Mononuclear and three-dimensional metal complexes based on a multidentate hydrazone ligand.

A potentially pentadentate hydrazone ligand, N'-[1-(pyrazin-2-yl)ethylidene]nicotinohydrazide (HL), was prepared from the condensation reaction of nicotinohydrazide and acetylpyrazine. Reactions of HL with MnCl2, Mn(CH3COO)2 and Cd(CH3COO)2 afforded three metal complexes, namely dichlorido{N'-[1-(pyrazin-2-yl-κN(1))ethylidene]nicotinohydrazide-κ(2)N',O}manganese(II), [MnCl2(C12H11N5O)], (I), bis{N'-[1-(pyrazin-2-yl-κN(1))ethylidene]nicotinohydrazidato-κ(2)N',O]manganese(II), [Mn(C12H10N5O)2], (II), and poly[[(acetato-κ(2)O,O'){μ3-N'-[1-(pyrazin-2-yl-κ(2)N(1):N(4))ethylidene]nicotinohydrazidato-κ(3)N',O:N(1)}cadmium(II)] chloroform disolvate], {[Cd(C12H10N5O)(CH3COO)]·2CHCl3}n, (III), respectively. Complex (I) has a mononuclear structure, the Mn(II) centre adopting a distorted square-pyramidal coordination.

Synthesis, crystal structures, and antibacterial evaluation of metal complexes based on functionalized 2-phenylquinoline derivatives.

A series of dinuclear paddle-wheel like transition metal complexes based on 2-phenylquinoline-4-carboxylic derivative L have been synthesized and characterized by IR, elemental analysis, and X-ray diffraction single crystal analysis. The biological activities of L and its complexes were evaluated as assayed antibacterial activities, including Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. The results indicated that these complexes showed better antibacterial activities than the free ligand or metal salts alone.
