Meta-analysis of antiviral protection of white spot syndrome virus vaccine to the shrimp.

Currently, white spot syndrome virus (WSSV) is one of the most serious pathogens that impacts shrimp farming around the world. A WSSV vaccine provides a significant protective benefit to the host shrimp. Although various types of vaccines against WSSV have emerged, the immune effects among them were not compared, and it remains unclear which type of vaccine has the strongest protective effect.

The protective effect of the earthworm active ingredients on hepatocellular injury induced by endoplasmic reticulum stress.

The earthworm is a widely used Chinese herbal medicine. There are more than 40 prescriptions including earthworms in the "Compendium of Materia Medica". TCM theory holds that earthworms exert antispasmodic and antipyretic effects through the liver meridian to calm the liver.

Neutralization of ADAM8 ameliorates liver injury and accelerates liver repair in carbon tetrachloride-induced acute liver injury.

Although some studies have described the function of ADAM8 (a disintegrin and metalloprotease 8) related with rheumatoid arthritis, cancer and asthma, etc., the concrete role of ADAM8 in acute liver injury is still unknown. So mice respectively received anti-ADAM8 monoclonal antibody (mAb) of 100 μg/100 μl, 200 μg/100 μl or 300 μg/100 μl in PBS or PBS pre-injection.

Proper heat shock pretreatment reduces acute liver injury induced by carbon tetrachloride and accelerates liver repair in mice.

Whether proper heat shock preconditioning can reduce liver injury and accelerate liver repair after acute liver injury is worth study. So mice received heat shock preconditioning at 40°C for 10 minutes (min), 20 min or 30 min and recovered at room temperature for 8 hours (h) under normal feeding conditions. Then acute liver injury was induced in the heat shock-pretreated mice and unheated control mice by intraperitoneal (i.

[Construction of lentiviral mediated CyPA siRNA and its functions in non-small cell lung cancer].

Objective: To construct a lentiviral-vector-mediated CyPA small interference RNA (siRNA) and study its function in non-small cell lung cancer.

Methods: First, four target sequences were selected according to CyPA mRNA sequence, the complementary DNA contained both sense and antisense oligonucleotides were designed, synthesized and cloned into the pGCL-GFP vector, which contained U6 promoter and green fluorescent protein (GFP). The resulting lentiviral vector containing CyPA shRNA was named Lv-shCyPA, and it was confirmed by PCR and sequencing.

[Antagonistic effects of vitamin E on the testicular injury by cyclophosphamide in mice].

Objective: To observe the protective effects of vitamin E on the testicular injury by cyclophosphamide in mice, and the correlative mechanism.

Methods: Fifty sexually mature male mice were randomly divided into five groups: the cyclophosphamide group (the CP group), the low-dose vitamin E group (the low-dose group), the middle-dose vitamin E group (the middle-dose group), the high-dose vitamin E group (the high-dose group), the matched control group (the control group). The first four groups were given cyclophosphamide by gavage at a dose of 5 mg/(kg x d).

[Analysis of sterile male semen of occupational drivers].

Objective: To explore the possible correlation between the driver's occupation and male semen quality.

Methods: Semen samples were collected from 1,223 infertile men (78 drivers and 1,145 non-drivers) and 100 normal men, and their liquefaction, sperm density, sperm vitality, sperm motility and sperm shape were analysed.

Results: The abnormal rates of semen quality in sterile male drivers were significantly higher than in non-drivers(P < 0.
