Circulatory recovery is as fast with air ventilation as with 100% oxygen after asphyxia-induced cardiac arrest in piglets.
We investigated return of spontaneous circulation and of cerebral oxygenation after asphyxia-induced cardiac arrest, using ventilation with air, throughout, or with 100% oxygen for a shorter or longer period. Arterial pressure, heart rate, regional cerebral oxygen saturation (CrSO2) and brain tissue oxygen tension (PbtO2) were measured in one day old piglets that were hypoventilated with air and l
Circulating maternal cortisol levels during vaginal delivery and elective cesarean section.
Maternal S-cortisol levels increase throughout pregnancy and peak in the third trimester. Even higher levels are seen during the physical stress of delivery. Since analgesia for women in labor has improved, it is possible that maternal stress during labor is reduced. The aim of this study was to compare maternal S-cortisol during vaginal delivery and elective cesarean section.
The idic(X)(q13) in myeloid malignancies: breakpoint clustering in segmental duplications and association with TET2 mutations.
Myelodysplastic syndromes and acute myeloid leukemia with an isodicentric X chromosome [idic(X)(q13)] occur in elderly women and frequently display ringed sideroblasts. Because of the rarity of idic(X)(q13), little is known about its formation, whether a fusion gene is generated, and patterns of additional aberrations. We here present a SNP array study of 14 idic(X)-positive myeloid malignancies,
A mathematical model for predicting the temperature distribution in laser-induced hyperthermia. Experimental evaluation and applications
A time-dependent mathematical model for the heat transfer in laser-induced hyperthermia has been developed. The model calculates the temperature distribution in surface-irradiated tissues. Good agreement was found between the predictions of the model and in vitro experimental results obtained for bovine liver irradiated with an expanded beam from a Nd:YAG laser. Surface evaporation of water was in
The expression of pluripotency marker Oct 3/4 in prostate cancer and benign prostate hyperplasia.
BACKGROUND: Oct 3/4 (Octamer 3/4), a member of POU family has been considered as an important stem cell marker and essential transcription factor during human embryogenesis. In recent years, there have also been reports on presence of Oct 3/4 in differentiated benign and malignant human cells. The objective of this study was to investigate the transcription and the protein expression of Oct 3/4 is
The OA Trial Bank: meta-analysis of individual patient data from knee and hip osteoarthritis trials show that patients with severe pain exhibit greater benefit from intra-articular glucocorticoids.
To evaluate the efficacy of intra-articular (IA) glucocorticoids for knee or hip osteoarthritis (OA) in specific subgroups of patients with severe pain and inflammatory signs using individual patient data (IPD) from existing trials.
Clinical application of long-term intensity and pitch matches in fluctuating low-frequency hearing loss.
The purpose of this study was to measure changes in intensity and pitch matches to better assess disease activity in fluctuating hearing loss. Long-term suprathreshold audiometry was carried out at home on a subject with a unilateral fluctuating low-frequency hearing loss during a period when the subject demonstrated no symptoms and a period when the subject reported hearing loss, aural pressure,
Serum transferrin carrying the xeno-tetrasaccharide NeuAc-Gal-GlcNAc2 is a biomarker of ALG1-CDG.
ALG1-CDG (formerly CDG-Ik) is a subtype of congenital disorders of glycosylation (CDG) where the genetic defect disrupts the synthesis of the lipid-linked oligosaccharide precursor required for N-glycosylation. The initial step in the investigation for these disorders involves the demonstration of hypoglycosylated serum transferrin (TF). There are no specific biomarkers of this CDG subtype known t
The “Perennial” Question: Nations in Antiquity or the Antique Shop of History?
Human pathogens utilize host extracellular matrix proteins laminin and collagen for adhesion and invasion of the host.
Laminin (Ln) and collagen are multifunctional glycoproteins that play an important role in cellular morphogenesis, cell signaling, tissue repair and cell migration. These proteins are ubiquitously present in tissues as a part of the basement membrane (BM), constitute a protective layer around blood capillaries, and are included in the extracellular matrix (ECM). As a component of BMs, both Lns and
Interactional resistance between patients with atrial fibrillation and cardiologists in consultation on treatment with warfarin: the value of shared decision-making
Rationale: Atrial fibrillation (AF) increases the risk of stroke and it can be reduced by treatment with warfarin. Some patients consider that warfarin is a stressful treatment with undesired effects and the perceived barriers include unwillingness to take it. Knowledge of patients resisting warfarin treatment may be useful for the potential threat to maintaining shared decision-making in the cons

Repeatability of T1-quantification in dGEMRIC for three different acquisition techniques: two-dimensional inversion recovery, three-dimensional look locker, and three-dimensional variable flip angle.
PURPOSE: To evaluate the repeatability of the dGEMRIC (delayed gadolinium enhanced MRI of cartilage) method in osteoarthritis-prone knee joints for three different T1 quantification techniques: two-dimensional inversion recovery (2D-IR), three-dimensional Look-Locker (3D-LL), and three-dimensional variable flip angle (3D-VFA). MATERIALS AND METHODS: Nine subjects were examined twice, with a 2-week
Abort-on-Fail Based Test Scheduling
The long andincreasing test application time for modular core-basedsystem-on-chips is a major problem, and many approaches have beendeveloped to deal with the problem. Different from previousapproaches, where it is assumed that all tests will be performeduntil completion, we consider the cases where the test process isterminated as soon as a defect is detected. Such abort-on-failtesting is common
ISO 9001 within the Swedish construction sector
This study analysed how the ISO 9000 framework could be employed in the construction process. Interviews were conducted at twelve companies in Sweden that utilized the quality system standard ISO 9001. Many of the concepts contained in the quality system standard were experienced as being too abstract and too difficult to comprehend. Frequently quality mangement was considered as serving the funct
Lung function, forced expiratory volume in 1 s decline and COPD hospitalisations over 44 years of follow-up.
The use of baseline lung function in the prediction of chronic obstructive pulmonary disease (COPD) hospitalisations, all-cause mortality and lung function decline was assessed in the population-based "Men Born in 1914" cohort.Spirometry was assessed at age 55 years in 689 subjects, of whom 392 had spirometry reassessed at age 68 years. The cohort was divided into three groups using fixed ratio (F

Serum chlamydial lipopolysaccharide as a prognostic factor for a new cardiovascular event.
BACKGROUND: Infections caused by Chlamydia pneumoniae are considered to participate in inflammatory processes leading to coronary artery disease. After a primary infection, the bacteria remain dormant intracellularly causing a chronic inflammatory stimulus. MATERIALS AND METHODS: Blood samples were obtained from 235 patients with acute myocardial infarction (AMI) and 108 patients with unstable ang
Atrial fibrillation in the Malmö diet and cancer study: a study of occurrence, risk factors and diagnostic validity.
The validity of atrial fibrillation (AF) diagnoses in national registers for use as endpoints in prospective studies has not been evaluated. We studied the validity of AF diagnoses in Swedish national hospital discharge and cause of death registers and the occurrence of and risk factors for AF in a middle-aged Swedish population using these registers. Our study included the 30,447 individuals (age
