Aim: To achieve a better understanding of the pathogenesis of new type gosling viral enteritis virus (NGVEV) and the relationship between NGVEV and host cells.
Methods: The apoptosis of duck embryo fibroblasts (DEF) induced by NGVEV was investigated by fluorescence-activated cell sorter (FACS) and fluorescence microscope after the cells were stained with Annexin V-FITC and propidium iodide (PI).
Results: By staining cells with a combination of fluorescein annexin V-FITC and PI, it is possible to distinguish and quantitatively analyze non-apoptotic cells (Annexin V-FITC negative/PI negative), early apoptotic cells (Annexin V-FITC positive/PI negative), late apoptotic/necrotic cells (Annexin V-FITC positive/PI positive) and dead cells (Annexin V-FITC negative/PI positive) through flow cytometry and fluorescence microscope.
Introduction: Epidemiological studies of rheumatic diseases have been conducted during the past 20 years in China. The aim of this study was to clarify prevalence rates of common rheumatic diseases in China.
Methods: Relevant reports of population-based surveys conducted from 1980 to 2006 were retrieved.
Objectives: A restricted neurological deficit is not uncommon in patients with cortical lesions. However, in cheiro-oral syndrome (COS) associated with cortical involvement, the topographic disparity of the cheiral and oral representation area is hardly explained by the restricted sensorium at the homolateral mouth angle/lip and finger/hand, with sparing of the facial structures.
Patients And Methods: In order to elucidate the factors of clinical significance and pathogenesis in cortical COS, 11 patients with COS associated with contralateral cortical lesions were analyzed, and the cases of similar patients described in the literature were reviewed.
Objective: To validate the differences of the prevalence of rheumatic symptoms between the north and south part of China and to investigate the associated risk factors for rheumatic complaints in Shantou, China.
Methods: Four samples together comprising 10,638 people > or = 16 years of age were surveyed in 1987, 1992, 1995, and 1999. The protocol of the ILAR-China Collaborative Study or the WHO-ILAR COPCORD Core Questionnaire was implemented.
Article Synopsis
- - The study aimed to assess the prevalence of knee pain (KP) and lumbar pain (LP) in a southern urban population of Chenghai City, comparing it to previous findings in rural southern and northern China, with a sample size of 2040 adults.
- - Results showed that 18.1% of participants reported rheumatic symptoms, with 7.5% experiencing KP (55% had osteoarthritic changes) and 11.5% with LP (69% showed degenerative changes).
- - Findings indicated that the prevalence of knee and lumbar pain in the southern urban population was lower than that in northern rural areas, and pain rates varied based on housing type, with those living in multi-level apartments reporting higher
Resistance in wheat (Triticum aestivum) to the Hessian fly (Mayetiola destructor), a major insect pest of wheat, is based on a gene-for-gene interaction. Close linkage (3 +/- 2 cM) was discovered between Hessian fly avirulence genes vH3 and vH5. Bulked segregant analysis revealed two DNA markers (28-178 and 23-201) within 10 cM of these loci and only 3 +/- 2 cM apart.

Methods: The Community Oriented Program for Control of Rheumatic Disease (COPCORD) Stage I study was carried out in 16 groups in the Trung Liet Commune, Dong Da District, Hanoi City, Vietnam. Phase 1: the WHO ILAR COPCORD Core Questionnaire was applied by primary health care workers to 2119 urban subjects aged 16 years and over.
