Cysteine 230 is essential for the structure and activity of the cytotoxic ligand TRAIL.

Unlike other tumor necrosis factor family members, the cytotoxic ligand tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)/Apo-2L contains an unpaired cysteine residue (Cys(230)) in its receptor-binding domain. Here we show that the biological activity of both soluble recombinant TRAIL and cell-associated, full-length TRAIL is critically dependent on the presence of Cys(230). Mutation of Cys(230) to alanine or serine strongly affected its ability to kill target cells. Binding to its receptors was decreased by at least 200-fold, and the stability of its trimeric structure was reduced. In recombinant TRAIL, Cys(230) was found engaged either in interchain disulfide bridge formation, resulting in poorly active TRAIL, or in the chelation of one zinc atom per TRAIL trimer in the active, pro-apoptotic form of TRAIL.

An Investigation of Signing Needs at Uncontrolled Local Road Intersections, HR-230, 1982

Iowa Counties have been experiencing significant tort claim liability due to the signing of local roads. One such problem is relative to the real or alleged need for signing at uncontrolled intersections of local roads. It has been assumed that the standard CROSS ROAD sign, which calls for a yellow diamond with a black cross, was sufficient to provide the necessary warning that a driver may be approaching an intersection which requires special precautionary driving attention. However, it is possible that this sign on a through highway might conflict with the legal status of the local county road. In light of this situation, it seemed worthwhile to know the extent to which uncontrolled local road intersections were perceived as a potential liability problem; the degree to which the standard CROSS ROAD sign communicated to the driver the message a county engineer wanted at these local road intersections; and whether there were any better signing alternatives available to communicate this hazard to the driver in this situation.

Seasonality of cardiovascular risk factors: an analysis including over 230 000 participants in 15 countries.

OBJECTIVE: To assess the seasonality of cardiovascular risk factors (CVRF) in a large set of population-based studies. METHODS: Cross-sectional data from 24 population-based studies from 15 countries, with a total sample size of 237 979 subjects. CVRFs included Body Mass Index (BMI) and waist circumference; systolic (SBP) and diastolic (DBP) blood pressure; total, high (HDL) and low (LDL) density lipoprotein cholesterol; triglycerides and glucose levels. Within each study, all data were adjusted for age, gender and current smoking. For blood pressure, lipids and glucose levels, further adjustments on BMI and drug treatment were performed. RESULTS: In the Northern and Southern Hemispheres, CVRFs levels tended to be higher in winter and lower in summer months. These patterns were observed for most studies. In the Northern Hemisphere, the estimated seasonal variations were 0.26 kg/m(2) for BMI, 0.6 cm for waist circumference, 2.9 mm Hg for SBP, 1.4 mm Hg for DBP, 0.02 mmol/L for triglycerides, 0.10 mmol/L for total cholesterol, 0.01 mmol/L for HDL cholesterol, 0.11 mmol/L for LDL cholesterol, and 0.07 mmol/L for glycaemia. Similar results were obtained when the analysis was restricted to studies collecting fasting blood samples. Similar seasonal variations were found for most CVRFs in the Southern Hemisphere, with the exception of waist circumference, HDL, and LDL cholesterol. CONCLUSIONS: CVRFs show a seasonal pattern characterised by higher levels in winter, and lower levels in summer. This pattern could contribute to the seasonality of CV mortality.

Proyecto de acondicionamiento del camino rural que une la N-230 con Coscolla en el término municipal de Puente de Montañana (Huesca)

El tema tractat en aquest Projecte es el condicionament del camí rural situat al terme municipal de Pont de Montanyana (Osca). Aquest Projecte conté quatre documents. En primer lloc trobem la memòria amb els seus corresponents annexos on es defineixen les característiques bàsiques a tenir en compte per a realitzar el condicionament. A continuació, trobem els plànols necessaris per a dur a terme l’obra. El tercer document es el plec de condicions en el que s’estipulen les normes que s’han de tenir en compte per executar el Projecte. L’últim document que trobem es el pressupost, on hi ha el cost aproximat de l’obra

Ocorrência de micoses e pitiose em animais domésticos: 230 casos

Para determinar as principais micoses e oomicoses que acometeram animais domésticos na área de abrangência do Laboratório de Patologia Veterinária (LPV) da Universidade Federal de Santa Maria (UFSM), foi realizado um estudo retrospectivo em 9.487 protocolos de necropsias e 20.199 exames histopatológicos (totalizando 29.686 casos), realizados no LPV-UFSM, entre janeiro de 1990 e dezembro de 2012. Do total de protocolos analisados, 230 apresentaram micoses ou pitiose (oomicose), sendo 179 casos (78%) de micoses e 51 casos (22%) de pitiose. Os protocolos foram revisados para determinar os principais achados referentes à epidemiologia, sinais clínicos e às alterações macroscópicas e microscópicas. Em dois casos (0,8%) não foi possível determinar o gênero ou o grupo do fungo observado. As principais doenças diagnosticadas, em ordem decrescente de prevalência, foram: pitiose, candidíase, aspergilose, zigomicose, dermatofitose, malasseziose, criptococose, megabacteriose e esporotricose. Outras doenças diagnosticadas numa única ocorrência cada foram histoplasmose e pneumocistose. Os equinos foram os mais acometidos pela pitiose e os animais de companhia (cães e gatos) foram os mais acometidos pelas micoses.

Coarse grained sediment with fine grained domains, clay material, rotation structures and lineations. Clasts range from sub-angular to sub-rounded. Mainly brown sediment with darker patches of brown throughout. Major amounts of grain crushing can be seen in the coarse grained material.
