ZnO-reduced graphene oxide composite based photoelectrochemical aptasensor for sensitive Cd(II) detection with methylene blue as sensitizer.

In this paper a photoelectrochemical (PEC) aptasensor based on specific recognition with conformational changed after the target Cd(II) identification was fabricated. A ZnO and reduced graphene oxide (ZnO-rGO) nanocomposite with enhanced PEC activity was designed as photoactive material. After the further incorporation of gold nanoparticles (AuNPs) with ZnO-rGO nanocomposite, the enhanced photocurrent signal could be detected owing to the localized surface plasmon resonance and good conductivity of AuNPs.

Photoelectrochemical aptasensor for lead(II) by exploiting the CdS nanoparticle-assisted photoactivity of TiO nanoparticles and by using the quercetin-copper(II) complex as the DNA intercalator.

A photoelectrochemical (PEC) aptasensor for Pb(II) detection is described. A nanocomposite consisting of CdS (2.5 μm) and TiO nanoparticles (10 nm) was used as a photoactive material, and gold nanochains (Au NCs) as the support for immobilization of the Pb(II)-binding aptamer.

[Infertility in polycystic ovary syndrome treated with acupuncture and clomiphene: a randomized controlled trial].

Objective: To explore the best therapy for infertility caused by polycystic ovary syndrome (PCOS).

Methods: One hundred and twenty patients were randomized into three groups, a clomi-phene group (group A), an acupuncture-moxibustion + Chinese medicine group (group B) and a clomiphene + acupuncture-moxibustion+ Chinese medicine group (group C), 40 cases in each one. In the group A, since the 5th day of menstruation, clomiphene was prescribed for oral administration.

[Effects of warm needling combined with zhangmo decoction on endometrial receptivity in patient with ovulation induction].

Objective: To explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

Methods: One hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied.

A novel nanoparticle containing MOG peptide with BTLA induces T cell tolerance and prevents multiple sclerosis.

Accumulative evidence demonstrates that multiple sclerosis (MS) is caused by activation of myelin Ag-reactive CD4+ T cells. Therefore, the CD4+ T cells specific for myelin Ag may be the important therapeutical target of MS. The novel coinhibitory receptor B and T lymphocyte attenuator (BTLA) may have a regulatory role in maintaining peripheral tolerance, however, its role in MS is still unknown.
