Interspecific variation in chloroplast low molecular weight (cLMW) HSP (heat shock protein) expression was examined with respect to phylogeny, species specific leaf area, chlorophyll fluorescence, and mean environmental conditions within species ranges. Eight species of Ceanothus (Rhamnaceae) were heat shocked for 4 h at several different temperatures. Leaf samples were collected immediately af...

BACKGROUND Reduction of retinal nerve fibre layer (RNFL) thickness was shown as part of the neurodegenerative process in a range of different neurodegenerative pathologies including Alzheimer's disease (AD), idiopathic Parkinson's disease (PD), spinocerebellar ataxia (SCA) and multiple system atrophy (MSA). To further clarify the specificity of RNFL thinning as a potential marker of neurodegene...

BACKGROUND A small percentage of children with Henoch-Schönlein purpura (HSP) develop a chronic form of the disease that often requires prolonged corticosteroid therapy. Disease modifying anti-rheumatic agents (DMARDs) or biologics have been successfully used to treat those refractory cases. Azathioprine is a DMARD that has been reported to be effective in HSP nephritis and in adult cutaneous l...

Stress or heat shock proteins are constitutively expressed in normal CNS tissues in a variety of cell types (oligodendrocytes, astrocytes, and neurons). Their presence may protect cells from various stresses, such as hypoxia, anoxia, and excessive excitatory stimulation. Increased amounts of hsp are expressed in various cells of the CNS during acute toxic-metabolic states and in chronic degener...

Cold storage and reperfusion injury to transplanted kidneys contributes to increased incidence of delayed graft function and may have a negative impact on graft survival. This study examined the mechanisms by which previous heat shock protects against cell death in an in vitro model of kidney storage. Cold storage is mimicked by incubating human renal proximal tubular epithelial (HK-2) cells in...

Tổn thương da đặc trưng của Henoch-Schönlein (HSP) là ban xuất huyết nổi gồ nhẹ ở phần xa hai chân và mông, thường hồi phục hoàn toàn không cần điều trị. bọng nước biểu hiện hiếm gặp trong HSP trẻ em, gây khó khăn cho chẩn đoán có thể để lại di chứng tại da. Chúng tôi báo cáo một trường hợp nam 9 tuổi cẳng viêm khớp, được trị bằng ibuprofen. Sau 8 ngày, tổn tiến triển thành các chân. Sinh thiết...

Arsenic is a known human carcinogen. These studies were designed to examine the impact of low arsenite concentrations on immediate early gene expression in precision-cut rat lung slices. Precision-cut lung slices are a versatile in-vitro system for toxicity studies, as they preserve the architecture and cellular heterogeneity of the lung. Since 0.1-100 microM arsenite did not compromise slice v...

BACKGROUND Due to an increased frequency of vasculitis in FMF patients, many investigators have studied MEFV mutations in patients with HSP. The aim of the study is to investigate the frequency and clinical significance of MEFV mutations in Egyptian children with Henoch-Schonlein purpura (HSP). Investigating MEFV mutations in controls may help in estimating the prevalence of MEFV mutation carri...

Immunisation against the mycobacterial heat shock protein (hsp-65) has been proposed to lead to production of autoantibodies against human lactoferrin. Such antibodies occur in ulcerative colitis and in primary sclerosing cholangitis. This study analysed the distribution of hsp-65 and lactoferrin in biopsy specimens from patients with inflammatory bowel disease and primary sclerosing cholangiti...

Henoch Schonlein Purpura (HSP) also known as IgA vasculitis, is an immune complex vasculitis affecting small vessels. We report a case of 53 years old female who presented with multiple reddish-brown purpuric papules over bilateral lower limb for 10 days. Her cutaneous findings were suggestive HSP. She had history recurrent dyspepsia the past 6 months which she been taking antacid from local ph...
