The pathogenesis of atherosclerosis and abdominal aortic aneurysm involves breakdown of the elastic laminae. Elastolytic cysteine proteases, including cathepsins S and K, are overexpressed at sites of arterial elastin damage, but whether endogenous local inhibitors counterbalance these proteases is unknown. We show here that, whereas cystatin C is normally expressed in vascular wall smooth muscle
BACKGROUND: Alterations of the charge-selective properties of the glomerular capillary wall are important constituents of the pathogenesis of many glomerular diseases. Thus, differences in the degree of such changes could be of help in understanding the mechanisms governing the transport of macromolecules across the glomerular capillary wall.METHODS: The ratio between urine concentrations of neutr
Osteoporosis is a major cause of morbidity worldwide. A number of risk factors, such as age and gender, are well established. High cadmium exposure causes renal damage and in severe cases also causes osteoporosis and osteomalacia. We have examined whether long-term low-level cadmium exposure increases the risk of osteoporosis. Bone mineral density (BMD) in the forearm was measured in 520 men and 5
Urine levels of albumin, orosomucoid (alias alpha1-acid glycoprotein), immunoglobulin G (IgG) and protein HC (alias alpha1-microglobulin) were determined in 247 healthy Swedish infants and children aged 1 day to 15 years. Urine samples were collected and stored in conditions known to guarantee stable protein levels. The protein levels were measured both as mass concentrations (mg l(-1)) and as pro
OBJECTIVES: To study the dose-response relation between cadmium dose and renal tubular damage in a population of workers and people environmentally or occupationally exposed to low concentrations of cadmium.METHODS: Early kidney damage in 1021 people, occupationally or environmentally exposed to cadmium, was assessed from cadmium in urine to estimate dose, and protein HC (alpha(1)-microglobulin) i
Cysteine protease-inhibiting proteins of the cystatin superfamily can inhibit the replication of certain viruses and bacteria. The inhibitory centre of human cystatin C, the most widely distributed human cystatin, comprises three peptide segments. The present work describes the synthesis and antibacterial activity of 27 new peptidyl derivatives or cyclopeptides based upon the aminoterminal segment
In Icelandic pedigrees a cystatin C mutation, glutamine 68 (L68Q), causes autosomal dominant cerebral amyloid angiopathy-related hemorrhage (CAAH). We examined 33 patients with sporadic CAAH for this mutation. None carried L68Q and, including this report, only one of 52 published cases of sporadic CAAH has had the cystatin C mutation. Despite vascular colocalization of cystatin C with amyloid beta
Botaniker donerar varje år tusentals pressade växter till Lunds universitets biologiska museum. Ibland handlar det om nyheter i Sveriges vilda flora. Nya för år 2020 är exempelvis prärielök, brittsommaraster och rosenfibbla.The first Swedish records of 19 taxa that first attracted attention in 2020 in the Lund Botanical Museum (LD) are reported and briefly discussed., viz. Allium ampeloprasum var. ampeloprasum, Allium cernuum, Arisaema amurense, Aster amellus, Crepis rubra, Cyclamen coum subsp. coum, Digitaria sanguinalis subsp. pectiniformis, Eleocharis cf. montevidensis, Fraxinus angustifolia, Helichrysum italicum,
We have purified and characterized a factor, from the conditioned medium of neural stem cell cultures, which is required for fibroblast growth factor 2's (FGF-2) mitogenic activity on neural stem cells. This autocrine/paracrine cofactor is a glycosylated form of cystatin C (CCg), whose N-glycosylation is required for its activity. We further demonstrated that, both in vitro and in vivo, neural ste
The present minireview of the place of cystatin C in clinical medicine emphasizes, and discuss the evidence, that cystatin C-based GFR-estimating equations do not require the use of vague terms like race and sex, that cystatin C-based GFR-esti mating equations are useful for both children and adults, including the elderly, that the best GFR-estimation requires simultaneous use of both cystatin C-
European populations are ethnically and culturally diverse due to international migration. Evidence indicates large ethnic inequalities in the prevalence of type 2 diabetes. This review discusses the burden of type 2 diabetes and its related complications, and the potential explanatory mechanisms among migrants in Europe. The current available data suggest that the rate of type 2 diabetes is highe
