Benthic foraminifera were cultured for five months at four temperatures (4, 7, 14 and 21 degrees C) to establish the temperature dependence of foraminiferal calcite delta O-18 and Mg/Ca. Two Bulimina species (B. aculeata and B. marginata) were most successful in terms of calcification, adding chambers at all four temperatures and reproducing at 7 and 14 degrees C. Foraminiferal delta O-18 values d

Impact of SBP vs. DBP decrement during orthostasis on cardiovascular events in hypertension is not clear.

Background-Carotid intima-media thickness (cIMT) is a widely accepted marker of subclinical atherosclerosis. To date, large-scale investigations of genetic determinants of cIMT are sparse. Methods and Results-To identify cIMT-associated genes and genetic variants, a discovery analysis using the Illumina 200K CardioMetabochip was conducted in 3430 subjects with detailed ultrasonographic determinati

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65-600 GeV is performed using 20.3 fb^{-1} of sqrt[s]=8 TeV pp collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits

Lack of or dysfunction in osteoclasts result in osteopetrosis, a group of rare but often severe, genetic disorders affecting skeletal tissue. Increase in bone mass results in skeletal malformation and bone marrow failure that may be fatal. Many of the underlying defects have lately been characterized in humans and in animal models of the disease. In humans, these defects often involve mutations in

Mitochondrial metabolism controls insulin secretion from the pancreatic beta-cell. Type 2 Diabetes evolves when the beta-cells fail to release appropriate amounts of insulin, causing metabolic dysregulation and hyperglycemia. It is attractive to assume that mitochondrial dysfunction plays a decisive role in these processes. Indeed, while being a rare condition, genetically determined dysfunction o

BACKGROUND: High doses of aspirin counteract the beneficial effects of angiotensin-converting enzyme (ACE) inhibitors. It is not known how low-dose aspirin, with concomitant ACE-inhibitor treatment, affects renal function. AIM: To study renal effects of different doses of aspirin in elderly healthy volunteers who had an activated renin-angiotensin system. METHODS: Sixteen subjects each received tw

We know little about the health consequences of human exposure to microorganisms in the environment. This may largely be due to the lack of universally accepted, sensitive, reproducible, non-discriminatory, and health relevant methods for characterizing the exposure. In this review, some of the different mass spectrometry methods that have been developed for measuring endotoxin and peptidoglycan f

Previous studies have shown that QRS prolongation is a sign of depressed collateral flow and increased rate of myocardial cell death during coronary occlusion. The aims of this study were to evaluate ischemic QRS prolongation as a biomarker of severe ischemia by establishing the relationship between prolongation and collateral flow experimentally in a dog model, and test if the same pattern of isc

A deficient retinoic acid signaling has been suggested to be an important cause of the clinical inefficacy of all-trans retinoic acid (ATRA) therapy in non-promyelocytic (non-PML) forms of acute myeloid leukemia (AML). The general aim of the present work was to explore novel ways to take advantage of the anti-leukemic potential of ATRA, and, specifically, to search for a synergism between ATRA and

Breathlessness is a major cause of suffering and distress and little is known about the trajectory of breathlessness near death.

The third Human Variome Project (HVP) Meeting "Integration and Implementation" was held under UNESCO Patronage in Paris, France, at the UNESCO Headquarters May 10-14, 2010. The major aims of the HVP are the collection, curation, and distribution of all human genetic variation affecting health. The HVP has drawn together disparate groups, by country, gene of interest, and expertise, who are working

Sclerosing epithelioid fibrosarcoma (SEF), first described in 1995, is a rare aggressive sarcoma morphologically defined by "epithelioid fibroblasts arranged in distinct cords and nests in a densely sclerotic, hyalinised stroma". SEF can mimic metastatic carcinoma within desmoplastic stroma, lymphoma and other mesenchymal neoplasms such as myoepithelioma, making it difficult to diagnose. In a subs

AIMS: Although atrial fibrillation is a frequent complication of an atrial septal defect (ASD) of the secundum type, the underlying mechanisms are poorly understood. Atrial conduction disturbances, manifested as a prolonged P-wave duration, have been suggested as a substrate for arrhythmia. Prolongation of the P-wave in unrepaired ASD has been demonstrated by means of the conventional ECG, but not

BACKGROUND: The amount of myocardium at risk (MaR) during acute coronary occlusion and the duration of occlusion are important determinants of final infarct size. The main goal of early reperfusion therapy is to salvage ischemic myocardium, thereby preserving left ventricular function. The aims of the present study were to test the feasibility of developing polar plot representations of MaR, for p

In a prospective cohort study, we observed that women with a history of irregular cycles have a 28% increased coronary heart disease risk and tended to have a higher type 2 diabetes risk as compared with women who had a regular cycle length of 27 to 29 days. This association could not be explained by metabolic risk factors or altered hormone levels.

BACKGROUND: The aim of the present study was to explore the occurrence of fibrocytes in tissue and to investigate whether the appearance of fibrocytes may be linked to structural changes of the parenchyme and vasculature in the lungs of patients with obliterative bronchiolitis (OB) following lung or bone marrow transplantation. METHODS: Identification of parenchyme, vasculature, and fibrocytes was
