Construction of an anchoring SSR marker genetic linkage map and detection of a sex-linked region in two dioecious populations of red bayberry.

Red bayberry () is an evergreen fruit tree found in southern China whose whole-genome sequence has recently been published. We updated the linkage map of the species by adding 118 SSR markers and the female-specific marker MrFT2_BD-SEX. The integrated map included eight linkage groups and spanned 491 cM.

Soft sensor design based on phase partition ensemble of LSSVR models for nonlinear batch processes.

Traditional single model based soft sensors may have poor performance on quality prediction for batch processes because of the strong nonlinearity, multiple-phase, and time-varying characteristics. Therefore, a phase partition based ensemble learning framework upon least squares support vector regression (LSSVR) is proposed for soft sensor modeling. Firstly, multiway principal component analysis (MPCA) is employed to handle high-dimensional datasets and extract essential correlation information.

The red bayberry genome and genetic basis of sex determination.

Morella rubra, red bayberry, is an economically important fruit tree in south China. Here, we assembled the first high-quality genome for both a female and a male individual of red bayberry. The genome size was 313-Mb, and 90% sequences were assembled into eight pseudo chromosome molecules, with 32 493 predicted genes.

Development of chitosan-pullulan composite nanoparticles for nasal delivery of vaccines: optimisation and cellular studies.

Nasal immunisation with nanoparticles has already shown promising results. In this study, nanoparticle composites carrying BSA for nasal vaccination prepared using electrostatic interaction process between polycation N-trimethyl chitosan chloride (TMC), chitosan glutamate (CG), chitosan chloride (CCl) and polyanion carboxymethyl pullulan (CMP). A mass ratio of 2:1 for TMC-CMP combination produced stable nanocarriers.

Whole-Genome Analysis of Diversity and SNP-Major Gene Association in Peach Germplasm.

Peach was domesticated in China more than four millennia ago and from there it spread world-wide. Since the middle of the last century, peach breeding programs have been very dynamic generating hundreds of new commercial varieties, however, in most cases such varieties derive from a limited collection of parental lines (founders). This is one reason for the observed low levels of variability of the commercial gene pool, implying that knowledge of the extent and distribution of genetic variability in peach is critical to allow the choice of adequate parents to confer enhanced productivity, adaptation and quality to improved varieties.

Cloning and identification of a novel thyroid hormone receptor β isoform expressed in the pituitary gland.

We have previously identified a novel Trβ isoform (TrβΔ) in the rat, in which a novel exon N (108 bps) was found between exon 3 and exon 4 of TrβΔ, which represents the only difference between TrβΔ and Trβ1. In this study, we searched for an elongated Trβ2-like subtype with one additional exon N. We successfully isolated the entire mRNA/cDNA of a novel elongated Trβ2 isoform via PCR in the rat pituitary gland.

[Peach genomics and genome-wide association study: a review].

Peach (Prunus persica (L.) Batsch) is one of the most predominant stone fruits in Rosaceae family. The broad climate adaption, diverse cultivation region and good fruit taste make it one of the favorate fruits by consumers.

[Knocking down TRPC1 expression by siRNA inhibits proliferation and invasiveness of human lung adenocarcinoma cell A549 in vitro].

Objective: To evaluate the effects of down-regulated expression of transient receptor potential canonical (TRPC1) by RNA interference (RNAi) on proliferation and invasiveness of human lung adenocarcinoma cell A549 in vitro.

Methods: A549 cells were transfected with chemically synthesized small interfering RNA (siRNA) targeting TRPC1 gene. The mRNA and protein of TRPC1 were analyzed by real-time polymerase chain reaction (PCR) and Western blot respectively.

Peach genetic resources: diversity, population structure and linkage disequilibrium.

Background: Peach (Prunus persica (L.) Batsch) is one of the most important model fruits in the Rosaceae family. Native to the west of China, where peach has been domesticated for more than 4,000 years, its cultivation spread from China to Persia, Mediterranean countries and to America.

Curative effect of pleural lavage on open chest trauma caused by seawater immersion.

Background And Objectives: Open chest trauma with seawater immersion can lead systematic inflammatory response and multiple organ dysfunction syndromes (MODS). Early intervention of seawater immersion significantly decreases mortality. This study aims to explore the curative effect of pleural lavage in the treatment of open chest trauma caused by seawater immersion on dogs.

Development of simple sequence repeat (SSR) markers from a genome survey of Chinese bayberry (Myrica rubra).

Background: Chinese bayberry (Myrica rubra Sieb. and Zucc.) is a subtropical evergreen tree originating in China.

[Clinical efficacy of Yangjing Decoction on idiopathic asthenozoospermia].

Objective: To evaluate the clinical effect of the Chinese medicine Yangjing Decoction on idiopathic asthenospermia.

Methods: This study included 62 patients with idiopathic asthenospermia diagnosed with the computer-assisted semen analysis system and other methods based on the WHO guidelines. The patients were equally randomized to a trial and a control group, the former treated with Yangjing Decoction at the dose of 400 ml bid, and the latter with Yougui Capsules tid, both for a course of 6 months.

TMC-MCC (N-trimethyl chitosan-mono-N-carboxymethyl chitosan) nanocomplexes for mucosal delivery of vaccines.

In this study, for the first time, TMC/MCC complex nanoparticles as a delivery system and as an adjuvant were developed and evaluated to obtain systemic and mucosal immune responses against nasally administered tetanus toxoid (TT). Nanoparticles were developed by complexation between the oppositely charged chitosan derivatives, N-trimethyl chitosan (TMC, polycationic) and mono-N-carboxymethyl chitosan (MCC, polyampholytic) without using any crosslinker for mucosal vaccination. The cellular viability was found to be higher with TMC/MCC complex compared to that of MCC and TMC alone.

Transfection by particle bombardment: delivery of plasmid DNA into mammalian cells using gene gun.

Background: Recently, particle bombardment has become increasingly popular as a transfection method, because of a reduced dependency on target cell characteristics. In this study, we evaluated in vitro gene transfer by particle bombardment.

Methods: gWIZ luciferase and gWIZ green fluorescent protein (GFP) plasmids were used as reporter genes.

Formulation of a microparticle carrier for oral polyplex-based DNA vaccines.

Oral induction of a disseminated mucosal immune response with polyplex-based DNA vaccines requires the delivery of intact polyplexes (polyelectrolyte complexes formed by self-assembly of plasmid DNA with a cationic polymer) to subepithelial lymphoid tissue (e.g. Peyer's patches) within the gastrointestinal tract.

Sustained expression in mammalian cells with DNA complexed with chitosan nanoparticles.

This work investigates the preparation and in vitro efficiency of chitosan gene transfection systems. Chitosan was used to prepare nanoparticles with a size range of 40-200 nm as determined using photon correlation spectroscopy (PCS) and 40-80 nm as determined using transmission electron microscopy (TEM). The ability of particles to complex DNA was investigated using gel retardation.
