sGC stimulation totally reverses hypoxia-induced pulmonary vasoconstriction alone and combined with dual endothelin-receptor blockade in a porcine model.

AIM: Stimulation of soluble guanylate cyclase (sGC) with BAY 41-8543 was hypothesized to attenuate acute hypoxic pulmonary vasoconstriction alone and combined with dual endothelin (ET)-receptor antagonist tezosentan. METHODS: Measurements were taken in 18 anaesthetized pigs with a mean ± SEM weight of 31.1 ± 0.4 kg, in normoxia (FiO(2) ~0.21) and hypoxia (FiO(2) ~0.10) without (control protocol

Reprogramming of neonatal SVZ progenitors by Islet-1 and Neurogenin-2.

The subventricular zone (SVZ) lining the lateral walls of the lateral ventricles is one of the major neurogenic areas in the postnatal brain. Precursor cells in the SVZ migrate via the rostral migratory stream to the olfactory bulb where they differentiate into neurons. Cell replacement strategies utilizing the recruitment of these endogenous progenitors and their progeny to different areas of the

Effect of successful parathyroidectomy on 24-hour ambulatory blood pressure in patients with primary hyperparathyroidism.

OBJECTIVE: The pathogenesis of hypertension in patients with primary hyperparathyroidism (PHPT) is unclear, and the prevailing opinion is that parathyroidectomy does not affect the blood pressure (BP). Most previous studies have been based on BP measurements at rest in a clinical setting. The aim of this study was to get additional information by 24-hour ambulatory measurements. DESIGN AND PATIENT

Putative role of SUMOylation in controlling the activity of deubiquitinating enzymes in cancer.

Deubiquitinating enzymes (DUBs) are specialized proteins that can recognize ubiquitinated proteins, and after direct interaction, deconjugate monomeric or polymeric ubiquitin chains, thus changing the fate of the substrates. This process is instrumental in mediating or changing downstream signaling pathways. Beside mutations and alterations in their expression levels, the activity and stability of

Withdrawal from Biobank Research: Considerations and the Way Forward.

The right to withdraw one's consent after having agreed to participate in research is a fundamental principle in contemporary research ethics. However, it has been questioned whether this right should apply to research conducted on donated biological samples, including stem cells and tissues from which stem cells can be derived. In this article we present some of the concerns that have been expres

High Brain Tissue Oxygen Tension during Ventilation with 100% Oxygen after Fetal Asphyxia in Newborn Sheep.

The optimal FiO2 for newborn resuscitation is still not settled. We hypothesized that short-lasting oxygen ventilation after intrauterine asphyxia would not cause arterial or cerebral hyperoxia, and therefore be innocuous. The umbilical cord of fetal sheep was clamped and 10 min later, after delivery, ventilation with air (n=7) or with 100% oxygen for 3 (n=6) or 30 min (n=5), followed by air, was

The role of the cartilage matrix in osteoarthritis.

Osteoarthritis (OA) involves all the structures of the joint. How the disease is initiated and what factors trigger the disease process remain unclear, although the mechanical environment seems to have a role. Our understanding of the biology of the disease has been hampered by the lack of access to tissue samples from patients with early stage disease, because clinically recognizable symptoms app

The ADL-staircase: further validation.

The aim was to psychometrically evaluate the activities of daily living (ADL)-staircase in various age groups. This age stratified, cross-sectional study comprised 826 individuals aged 18-102 years. The factor structure was assessed by means of hierarchical cluster analyses, plots and analyses of nonclassifiable responses. Reliability was assessed in terms of internal consistency. In general, the

Injury Is a Major Inducer of Epidermal Innate Immune Responses during Wound Healing.

We examined the importance of injury for the epidermal innate immune response in human skin wounds. We found that injury, independent of infiltrating inflammatory cells, generated prominent chemotactic activity toward neutrophils in injured skin because of IL-8 production. Furthermore, injury was a major inducer of the expression of antimicrobial (poly)peptides (AMPs) in skin wounds. In human skin

A ground-validated NDVI dataset for monitoring vegetation dynamics and mapping phenology in Fennoscandia and the Kola peninsula

An NDVI dataset covering Fennoscandia and the Kola peninsula was created for vegetation and climate studies, using Moderate Resolution Imaging Spectroradiometer 16-day maximum value composite data from 2000 to 2005. To create the dataset, ( 1) the influence of the polar night and snow on the NDVI values was removed by replacing NDVI values in winter with a pixel- specific NDVI value representing t

Group antenatal care: new pedagogic method for antenatal care-a pilot study.

OBJECTIVE: to investigate how women who attended group antenatal care experienced the information they received, compared with women who attended traditional antenatal care, and their satisfaction with the form of care. The aim was also to determine the effect of group antenatal care on women's social networks compared with traditional antenatal care. DESIGN AND SETTING: a pilot study with an inte

Predictors of long-term beneficial effects on blood pressure after percutaneous transluminal renal angioplasty in atherosclerotic renal artery stenosis.

AIM: This retrospective study evaluated long-term effects of percutaneous transluminal renal angioplasty (PTRA) in atherosclerotic renal artery stenosis (ARAS), and predictors of benefit on blood pressure (BP). METHODS: During 1997-2003, 234 patients (age 69+/-11 years, 138 [59%] males) underwent PTRA for ARAS at Malmö Vascular Centre. Cure was defined as diastolic (D)BP

Robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy with short and long term morbidity data.

OBJECTIVE: To evaluate feasibility and morbidity of robot assisted laparoscopic radical hysterectomy. METHODS: From December 2005 to September 2008 robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed on 80 women. Using a prospective protocol, and an active investigation policy for defined adverse events, perioperative, short and long term data were obtained. R

Routine assessment of performance status during palliative chemotherapy when approaching end-of-life.

Palliative chemotherapy treatment (PCT) offered late in the cancer disease trajectory may be problematic. It is not easy to accurately calculate whether the potential benefits will outweigh the side-effects. This study investigates whether routine use of the Performance Status in Palliative Chemotherapy questionnaire (PSPC) affects the proportions of patients receiving PCT during the last month of

Incidence and mortality in epithelial ovarian cancer by family history of any cancer.

BACKGROUND: Practically all data on familial risk in ovarian and other cancers are based on incident cancer, whereas familiality in cancer mortality is largely unknown. If fatal forms of cancer are a highly familial subtype, then familial risk for mortality may exceed that of incidence, which is relevant for clinical decision making and counseling. METHODS: Ovarian cancer patients in the nationwid
