Dimethyl sulfoxide (DMSO) is a stabilizing co-solvent for G-quadruplex DNA.

We report the effect of dimethyl sulfoxide (DMSO) on the stability of the four-stranded structures formed by the oligodeoxyribonucleotides d[5'-AGGG(TTAGGG)-3'] (HTel), d[5'-(GGGT)GGG-3'] (G3T), d[5'-GGTTGGTGTGGTTGG-3] (TBA), d[5'-GGGGTTTTGGGG-3'] (Oxy-1.5), and d[5'-TGGGGT-3'] (TG4T). In these measurements, influence of the co-solvent was assessed by the change in the mid-point of the heat-induced unfolding, T, by monitoring the change in the UV absorption of the sample.

Prognostic value of pretreatment systemic immune-inflammation index in patients with gastrointestinal cancers.

Background: Numerous studies have reported the relationship between systemic immune-inflammation index (SII) and prognosis in gastrointestinal (GI) cancers, but no consensus has been reached. We aimed to systematically evaluate the prognostic value of SII in patients with GI cancers.

Methods: Relevant published papers regarding the prognostic value of SII in patients with GI cancers were obtained from a number of electronic databases.

Effects of 200 Gy Co-γ Radiation on the Regulation of Antioxidant Enzymes, Hsp70 Genes, and Serum Molecules of (Linnaeus).

The diamondback moth, (Linnaeus), is one of the notorious pests causing substantial loses to many cruciferous vegetables across the nations. The effects of Co-γ radiation on physiology of were investigated and the results displayed that 200 Gy irradiation significantly alters the antioxidant enzyme regulation in six-day-old male pupae of . First, in our research, we detected Oxidase system and stress response mechanism of irradiated pupae, the results displayed that 200 Gy irradiation significantly alters the antioxidant enzyme regulation in six-day-old male pupae of .

Geometry and Evolution of the Cangdong Sag in the Bohai Bay Basin, China: Implications for Subduction of the Pacific Plate.

The Cangdong Sag is a complex Cenozoic rift basin at the center of the Bohai Bay Basin. Cenozoic structures in the Cangdong Sag can be subdivided into the Cangdong Fault System in the west and the Xuxi Fault System in the east. The geometry of the boundary faults varies along the axes of half-grabens.

TPGS-Functionalized Polydopamine-Modified Mesoporous Silica as Drug Nanocarriers for Enhanced Lung Cancer Chemotherapy against Multidrug Resistance.

A nanocarrier system of d-a-tocopheryl polyethylene glycol 1000 succinate (TPGS)-functionalized polydopamine-coated mesoporous silica nanoparticles (NPs) is developed for sustainable and pH-responsive delivery of doxorubicin (DOX) as a model drug for the treatment of drug-resistant nonsmall cell lung cancer. Such nanoparticles are of desired particle size, drug loading, and drug release profile. The surface morphology, surface charge, and surface chemical properties are also successfully characterized by a series of techniques such as transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) method, thermal gravimetric analysis (TGA), dynamic light scattering (DLS), and Fourier transform infrared spectroscopy (FTIR).

Molecular Effects of Irradiation (Cobalt-60) on the Control of Panonychus citri (Acari: Tetranychidae).

The effective dose of irradiation to control pest mites in quarantine has been studied extensively, but the molecular mechanisms underlying the effects of the irradiation on mites are largely unknown. In this study, exposure to 400 Gy of γ rays had significant (p < 0.05) effects on the adult survival, fecundity and egg viability of Panonychus citri.
