Characterization of interploid hybrids from crosses between Brassica juncea and B. oleracea and the production of yellow-seeded B. napus.

Yellow-seeded Brassica napus was for the first time developed from interspecific crosses using yellow-seeded B. juncea (AABB), yellow-seeded B. oleracea (CC), and black-seeded artificial B.

The experiences of Chinese patients with coronary heart disease.

Aim: To explore the experiences of patients with coronary heart disease in China.

Background: The morbidity and mortality rates of people with coronary heart disease have been growing rapidly in the past decades in China, yet little is known about the experiences of Chinese patients with the disease.

Design: A qualitative descriptive study.

Rescue intracytoplasmic sperm injection: a prospective randomized study.

Objective: To determine the optimum rescue time by comparison of results of rescue intracytoplasmic sperm injection (ICSI).

Study Design: A total of 112 couples of total fertilization failure, who had retrieved at least four mature oocytes, were prospectively randomized into two groups: the earlier rescue group, rescue ICSI performed between 4 and 6 hours after insemination, and the control group, rescue ICSI performed between 6 and 8 hours after insemination.

Results: There were no statistically significant differences in woman's age, duration of infertility, number of oocytes retrieved every cycle, and number of embryos transferred every cycle between the two groups.

A comparison of postnatal depression and related factors between Chinese new mothers and fathers.

Aims: This study aims to examine the differences in the prevalence of depression and related factors between new mothers and fathers during the postnatal period.

Background: Although the transition to motherhood and postnatal depression has been extensively studied, few studies compared maternal and paternal psychological health during the postnatal period.

Design: A cross-sectional design was used.

Identification, fine mapping and characterisation of a dwarf mutant (bnaC.dwf) in Brassica napus.

In the present study, we have obtained one dwarf mutant (bnaC.dwf) from the Brassica napus inbred line T6 through chemical mutagen ethyl methanesulfonate (EMS). We have determined the phenotypic effects and genetic characteristics of dwarf mutant (bnaC.

Impact of the coxsackie and adenovirus receptor (CAR) on glioma cell growth and invasion: requirement for the C-terminal domain.

Expression of the coxsackie and adenovirus receptor (CAR) is downregulated in malignant glioma cell lines and is barely detectable in high-grade primary astrocytoma (glioblastoma multiforme). We determined the effect of forced CAR expression on the invasion and growth of the human glioma cell line U87-MG, which does not express any CAR. Although retrovirally mediated expression of full-length CAR in U87-MG cells did not affect monolayer growth in vitro, it did reduce glioma cell invasion in a 3-dimensional spheroid model.

[Activation of Ca(2+)-activated K+ channels by oxyphenamone in rabbit mesenteric vascular smooth muscle cells].

Aim: To study the effects of oxyphenamone (Oxy) on activation of Ca(2+)-activated K+ channels in rabbit mesenteric vascular smooth muscle cells.

Methods: To measure the effect of Oxy on the Ca(2+)-activated K+ channel (BK (Ca) channel) activity in rabbit mesenteric vascular smooth muscle cells by using whole cell patch clamp techniques.

Results: Oxy reversibly increase BK (Ca) channel activity in rabbit mesenteric artery smooth muscle cells.

Neuroprotective mechanism of modafinil on Parkinson disease induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine.

Aim: To observe the neuroprotective mechanism of modafinil on Parkinson disease (PD) models induced by 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP).

Methods: The model of PD was induced by intraperitoneally injecting MPTP into C57BL/6J mice for 4 d. Modafinil (i.
