Titanium dioxide (TiO) photocatalytic technology has the advantages of high catalytic activity, high chemical stability, nontoxicity, and low cost. Therefore, it finds widespread applications in the degradation of organic pollutants in water, antibacterial, environmental purification, and other fields. In this study, we have obtained a photocatalyst by modifying nanoTiO with the photosensitizer thioxanthone.

Design: Prospective validation study.
Setting: The study was conducted in four public hospitals in Hangzhou, a southeast coastal city of China.
To explore features of carbohydrate metabolism and evolution of carbohydrate metabolism-associated genes in herbivorous fishes, the open reading frames (ORF) of PKL, PKMa, and PKMb genes of grass carp (Ctenopharyngodon idella) were obtained, encoding 538, 528, and 532 amino acids, respectively. Comparative genomic analysis showed that adjacent PK genes were highly conserved between fish and mammals. Gene expression profiles were quite different between the three PK genes in tissues and at developmental stages.

Background: With the increasing rate of obstetric anal sphincter injuries, great controversy surrounds the "Hands-on" or "Hands-off" method during childbirth to decrease obstetric anal sphincter injuries incidence. Without regular records and related research, determining the use of this technique in China is difficult.

The mechanisms underlying the initiation and progression of OSCC are complex and not yet fully understood; however, this information is critical for developing novel therapeutic targets and improving patient outcome. Rab14, a Ras related protein, has been implicated in multiple forms of cancer.

In contrast to traditional methods, this paper adopts topology optimization based on the solid isotropic materials with penalization method on the truss structure design. Through reasonable object function and constraint choice, optimal topology results that have concerned the effect of gravity in the X, Y, and Z axis are achieved.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software.

A previous study has shown that miR-335 is downregulated in breast cancer and can suppress tumor invasion and metastasis. Emerging evidences indicate that c-Met is implicated in cell scattering, migration, and invasion.

The Salt Overly Sensitive (SOS) signal-transduction pathway plays a key role in ion homeostasis and salt tolerance in plants. Here, we report that overexpression of Arabidopsis thaliana SOS1+SOS2+SOS3 genes enhanced salt tolerance in tall fescue.

For goldfish (Carassius auratus), there are many varieties with different eye phenotypes due to artificial selection and adaptive evolution. Dragon eye is a variant eye characterized by a large-size eyeball protruding out of the socket similar to the eye of dragon in Chinese legends. In this study, anatomical structure of the goldfish dragon eye was compared with that of the common eye, and a stretching of the retina was observed in the enlarged dragon eye.

A simple, rapid and inexpensive fluorimetric method for simultaneously determining ASA and SA in a single scan of the co-existing specimen had been established. When the wavelength interval (delta lambda) is 80 nm for scaning, the amounts of ASA and AS could be quantitatively determined respectively. The fluorescence intensity was linearly related to the aspirin concentration in the range of 4.

Cystatin, which widely distributed in both tissues and body fluids of animal and plant, was a superfamily of cysteine proteinase inhibitors. It could form activity-inhibitor complexes with cysteine proteinases to inhibit the hydrolytic activity of proteinases. Cystatin played important roles not only in the inhibition of the proteolytic degradation of fish muscle, but also in biological defense systems against invaders.
