Effects on brain edema of crystalloid and albumin fluid resuscitation after brain trauma and hemorrhage in the rat.

BACKGROUND: It has been hypothesized that resuscitation with crystalloids after brain trauma increases brain edema compared with colloids, but previous studies on the subject have been inconclusive. To test this hypothesis, the authors compared groups resuscitated with either colloid or crystalloid. METHODS: After fluid percussion injury, rats were subjected to a controlled hemorrhage of 20 ml/kg

Restrictions on the rate of absorption when evaluating sorption isotherms obtained using a micro-calorimetric technique

One interestingway of measuring sorption isotherms and heats of sorption is the newly developed micro-calorimetric method. It turns out, however, that the adsorption kinetics must be proven to be rapid enough to fulfill the assumptions behind the theory for the determination of the isotherm to be valid. Here, the lower limit of the accepted rate of adsorption will be analyzed by making calculation

Intra-individual variation of the sperm chromatin structure assay DNA fragmentation index in men from infertile couples.

BACKGROUNDThe sperm chromatin structure assay (SCSA) is a valuable tool for prediction of fertility in vivo, with DNA fragmentation index (DFI) of 30% as a clinically useful cut-off level. Previous studies on fertile men have shown a high level of repeatability, with an intra-individual variability in DFI of ∼10%. However, conflicting data on how much the DFI fluctuates within individuals exist. T

Psychosocial coping profiles after pain rehabilitation: associations with occupational performance and patient characteristics.

Purpose The aims of the present study were to assess: (i) changes in coping by use of Multidimensional Pain Inventory profiles from baseline to follow-up, (ii) associations between Adaptive Coper (AC) profiles at follow-up and improvements in occupational performance (by Canadian Occupational Performance Measure COPM) and (iii) ability to predict AC profiles at follow-up by participants' baseline

Reduced expression of CYLD in human colon and hepatocellular carcinomas

CYLD was originally identified as a tumor suppressor that is mutated in familial cylindromatosis. Recent studies suggested a role for CYLD in nuclear factor-kappaB (NF-kappaB) regulation. NF-kappaB activation has been connected with multiple aspects of oncogenesis but the underlying molecular mechanisms of persistent NF-kappaB activation in tumors remain largely unknown. Thus, we evaluated CYLD tr

Practical suggestions on how to differentiate dementia with Lewy bodies from Alzheimer's disease with common cognitive tests.

OBJECTIVE: Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia, but it is often underdiagnosed and mistaken for Alzheimer's disease (AD) with sometimes lethal consequences. Over 35 studies have established the differences between DLB and AD in neuropsychological tests, but none have provided easy interpretations of common tests suitable for the clinician. The aim o

Mucosa-associated bacteria in two middle-aged women diagnosed with collagenous colitis.

AIM: To characterize the colon microbiota in two women histologically diagnosed with collagenous colitis using a culture-independent method. METHODS: Biopsies were taken from the ascending colon and the total DNA was extracted. Universal bacterial primers were used to amplify the bacterial 16S rRNA genes. The amplicons were then cloned into competent Escherichia coli cells. The clones were sequen

Smoking-Related Changes in Cerebral Perfusion in a Population of Elderly Men.

Aim: Smoking and hypertension are known causes of stroke and dementia. This study was designed to test the longitudinal effect of lifestyle factors and hypertension on cerebral blood flow (CBF) in old age. Method: A study of an unselected population cohort of 703 men, born in 1914, has been in progress since 1968 and the last clinical examination occurred at age 69. CBF was examined in 129 survivo

Soil metaproteomics: a review of an emerging environmental science. Significance, methodology and perspectives

Soil is a dynamic system in which microorganisms perform important tasks in organic matter transformations and nutrient cycles. Recently, some studies have started to focus on soil metaproteomics as a tool for understanding the function and the role of members of the microbial community. The aim of our work was to provide a review of soil proteomics by looking at the methodologies used in order to

Association between plasma homocysteine levels and mortality in elderly patients with mental illness.

BACKGROUND/METHOD: Total plasma homocysteine (tHcy) concentration is elevated in elderly patients with mental illness. Plasma tHcy is known to be associated with cardiovascular disease, renal impairment and negative lifestyle factors, and has been shown to predict mortality in human subjects. Epidemiological data on this topic in elderly patients with mental illness are missing. We therefore inves

Correlation of Geographical Location with Stable Isotope Values of Hydrogen and Carbon of Fatty Acids from New Zealand Milk and Bulk Milk Powder

The aim of this study was to investigate the correlation of δ²H and δ¹³C of bulk milk powder and milk powder fatty acids to their production region. A total of 46 milk powder samples from across New Zealand were collected and analyzed. Principal component analysis (PCA) showed that the δ²H and δ¹³C of four fatty acids (C4:0, C14:0, C16:0, C18:1) and bulk milk powder were found to be correlated wit

Theory of high-order harmonic generation by an elliptically polarized laser field

We generalize a recently formulated theory of high-order harmonic generation by low-frequency laser fields [Anne L'Huillier et al., Phys. Rev. A 48, R3433 (1993)] to the case of an elliptically polarized light. Our theoretical description includes both the single-atom response and propagation. Phase matching significantly modifies the results obtained in the single-atom response. The results of ou

A school-based exercise intervention program increases muscle strength in prepubertal boys.

This prospective controlled intervention study over 12 months evaluated the effect of exercise on muscular function, physical ability, and body composition in pre-pubertal boys. Sixty-eight boys aged 6-8 years, involved in a general school-based exercise program of 40 min per school day (200 min/week), were compared with 46 age-matched boys who participated in the general Swedish physical educatio

A genotype dependent intermediate ECG phenotype in patients with persistent lone atrial fibrillation

Background— Atrial fibrillation (AF) is heterogeneous at the clinical and molecular levels. Association studies have reported that common single-nucleotide polymorphisms in KCNE1 and SCN5A may predispose to AF. In this study, we tested the hypothesis that specific AF-associated genotypes confer variation on the appearance of AF assessed by analysis of fibrillatory rate of the atria. Methods and R
