Aim: To evaluate whether epigallocatechin-3-gallate acts on endometriosis mouse, and changes the status of DNA methylation of E-cadherin promoter region.
Methods: According to our previous research, the tracing nude mouse model of endometriosis was built up and randomly divided into three groups: control group (group A), epigallocatechin-3-gallate group (group B) and decitabine group (group C). Normal saline, epigallocatechin-3-gallate and decitabine were isometrically intraperitoneally injected into each group once in 2 days.
Genetically modified (GM) crops have achieved success in the marketplace and their benefits extend beyond the overall increase in harvest yields to include lowered use of insecticides and decreased carbon dioxide emissions. The most widely grown GM crops contain gene/s for targeted insect protection, herbicide tolerance, or both. Plant expression of Bacillus thuringiensis (Bt) crystal (Cry) insecticidal proteins have been the primary way to impart insect resistance in GM crops.

PARs mediate the activation of cells via thrombin, serine and other proteases. Such protease-triggered signaling events are thought to be critical for hemostasis, thrombosis and other normal pathological processes.

Methods: The patients enrolled in the study were treated for more than one year by sublingual immunotherapy (SLIT) using Dermatophagoides farinae drops and were divided into a monosensitized group (n = 20) and a polysensitized group (n = 30). Total nasal symptom scores of patients before and after SLIT were analyzed to evaluate the curative effect.
Per a 6 and Bla g 6 are cockroach allergens found in Periplaneta americana and Blattella germanica, respectively. The objective of the present study was to predict the B‑ and T‑cell epitopes of the Per a 6 and Bla g 6 allergens. Three immunoinformatics tools, the DNAStar Protean system, the Bioinformatics Predicted Antigenic Peptides system and the BepiPred 1.

Background: ADULT syndrome (acro-dermato-ungual-lacrimal-tooth syndrome) is a rare ectodermal dysplasia disorder known as autosomal dominant inheritance. Recent studies have linked p63 gene mutation to the development of this disease. However, the genetic characteristics of ADULT syndrome were still not well understood.

Objective: To explore the establishment of the mimetic aging effect in guinea pigs induced by D-galactose, and to detect the biological indicatrix associated with hearing loss and provide a new tool for molecular pathogenesis of hearing loss.
Methods: Total of 51 guinea pigs were randomly divided into three groups: group A (model aging group, n = 25), which were injected with D-galactose (200 mgxkg(-1)xd(-1)) by intra peritoneum for 6 weeks, group B (model control group, n = 18), which were given the same amount of saline only, and group C (vacant group, n = 15) were not treated. Then, The guinea pigs in group A and B were exposed in noise for 8 days, 8 hours once a day.
Aim: To clone the pollen allergen genes in Humulus scandens (Lour) Merr (LvCao in Chinese) and short ragweed (Ambrosia artemisiifolia L) for recombinant allergen production and immunotherapy.
Methods: The allergen genes were selectively amplified in the weed pollen cDNA pool by using a special PCR profile, with the primers designed by a modeling procedure. Following truncated gene cloning and confirmation of the pollen source, unknown 3'cDNA ends were identified by using the 3'-RACE method.
Aim: To obtain the entire gene open reading frame (ORF) and to construct the expression vectors for recombinant allergen production.
Methods: Gene fragments corresponding to the gene specific region and the cDNA ends of pollen allergens of short ragweed (Rg, Ambrosia artemisiifolia L.) were obtained by pan-degenerate primer-based PCR and rapid amplification of the cDNA ends (RACE), and the products were mixed to serve as the bridging PCR (BPCR) template.

Aim: To establish a stable and reliable method for fast cloning homologous genes of pollen allergens in allergen-containing plants.
Methods: Degenerate primers were designed based on the bioinformatic analysis of numerous allergens available from the database. Subsequent amplification of the allergen genes was conducted in the weed pollen cDNA pool by a selective PCR profile.
It has been a long haul but photoperiod- and thermo-sensitive genic male sterile (PTGMS) rice has not been freely used in hybrid rice production because there are two perplexing problems corresponding to the critical sterility temperature point (CSTP): the uncertainty of the CSTP segregating pattern and the instability of CSTP for every originally useful line. N5088S, the most widely commercialized japonica-type PTGMS line in China, also saw that its CSTP variants have been isolated but with all other agronomic characteristics unchanged. In this report we analyzed the genetic basis of CSTP, by employing the iterated expectation and conditional maximization (IECM) algorithm on four tiller-splitting-formed sets of seven generations from N5088S and its CSTP-variant H5088S, each set treated with one temperature regime.

The results showed that, whether it was under long daylight and high temperature or under long daylight and middle temperature, the mean natural seed-set percent of F1 was higher than 68.75%, suggesting that Nanjing11 could completely restore the fertility of Pei'ai 64S.
