High Serum Testosterone Is Associated With Reduced Risk of Cardiovascular Events in Elderly Men The MrOS (Osteoporotic Fractures in Men) Study in Sweden

Objectives We tested the hypothesis that serum total testosterone and sex hormone-binding globulin (SHBG) levels predict cardiovascular (CV) events in community-dwelling elderly men. Background Low serum testosterone is associated with increased adiposity, an adverse metabolic risk profile, and atherosclerosis. However, few prospective studies have demonstrated a protective link between endogenous

Inhibition of geranylgeranyltransferase attenuates neutrophil accumulation and tissue injury in severe acute pancreatitis.

Leukocyte infiltration and acinar cell necrosis are hallmarks of severe AP, but the signaling pathways regulating inflammation and organ injury in the pancreas remain elusive. In the present study, we investigated the role of geranylgeranyltransferase in AP. Male C57BL/6 mice were treated with a geranylgeranyltransferase inhibitor GGTI-2133 (20 mg/kg) prior to induction of pancreatitis by infusion

Towards eliminating systematic errors caused by the experimental conditions in Biochemical Methane Potential (BMP) tests.

The Biochemical Methane Potential (BMP) test is increasingly recognised as a tool for selecting and pricing biomass material for production of biogas. However, the results for the same substrate often differ between laboratories and much work to standardise such tests is still needed. In the current study, the effects from four environmental factors (i.e. ambient temperature and pressure, water va

Testing for predictability in panels of any time series dimension

The few panel data tests for predictability of returns that exist are based on the prerequisite that both the number of time series observations, $T$, and the number of cross-section units, $N$, are large. As a result, these tests are impossible for stock markets where lengthy time series data are scarce. In response to this, the current paper develops a new test for predictability in panels where

Assessment of human sinus cavity air volume using tunable diode laser spectroscopy, with application to sinusitis diagnostics.

Sinusitis is a very common disease and improved diagnostic tools are desirable also in view of reducing over-prescription of antibiotics. A non-intrusive optical technique called GASMAS (GAs in Scattering Media Absorption Spectroscopy), which has a true potential of being developed into an important complement to other means of detection, was utilized in this work. Water vapor in the frontal sinus

Representing Pain in Film : A Phenomenological Approach to Gibson, Tarantino and Lynch

What does pain look like? Pain is felt, as every human being knows. But what about its visibility? Is it possible to depict pain? We can represent its visible expressions. We can also, to a certain extent, capture that which causes pain. But what about pain itself? This paper addresses the question of how to represent pain from a phenomenological perspective. Adopting the phenomenological analysis

Autonomous and Controlled Motivation for Parenting: Associations with Parent and Child Outcomes

The present investigation examined motivation for parenting and some of its correlates in parents and children. The data came from samples of 151 first-time mothers of infants, 153 mothers of middle school children, and 260 mothers and fathers of high school children. Parents provided self-report data about their motivation in their parenting role as well as reports of role satisfaction, parental

Integrating candidate gene and quantitative genetic approaches to understand variation in timing of breeding in wild tit populations.

Two commonly used techniques for estimating the effect of genes on traits in wild populations are the candidate gene approach and quantitative genetic analyses. However, whether these two approaches measure the same underlying processes remains unresolved. Here, we use these two methods to test whether they are alternative or complementary approaches to understanding genetic variation in the timin

Involvement of Matrix Metalloproteinase-9 in Amyloid-β 1-42-Induced Shedding of the Pericyte Proteoglycan NG2.

Deposition of amyloid-β (Aβ) 1-42, the major component of senile plaques characteristic of Alzheimer disease, affects brain microvascular integrity and causes blood-brain barrier dysfunction, increased angiogenesis, and pericyte degeneration. To understand the cellular events underlying Aβ1-42 effects on microvascular alterations, we investigated whether different aggregation forms of Aβ1-42 affec

Swelling and polymer erosion for poly(ethylene oxide) tablets of different molecular weights polydispersities.

The aim of the study was to determine and compare the degree of swelling and the swelling kinetics of poly(ethylene oxide) (PEO) hydrophilic matrix tablets without any additives for matrixes with different molecular weight polydispersities. A wide range of "mixed" polydisperse PEO tablets were obtained by mixing two PEO batches with average molecular weights of 10(5) and 2 x 10(6), respectively. T

Ras regulates alveolar macrophage formation of CXC chemokines and neutrophil activation in streptococcal M1 protein-induced lung injury.

Streptococcal toxic shock syndrome (STSS) is associated with a high mortality rate. The M1 serotype of Streptococcus pyogenes is most frequently associated with STSS. Herein, we examined the role of Ras signaling in M1 protein-induced lung injury. Male C57BL/6 mice received the Ras inhibitor (farnesylthiosalicylic acid, FTS) prior to M1 protein challenge. Bronchoalveolar fluid and lung tissue were

Optical Properties Assessment for Liquid Phantoms Using Fiber Based Frequency-Modulated Light Scattering Interferometry

Fiber based frequency-modulated light scattering interferometry (FMLSI) is developed for optical properties studies of liquid phantoms, made of Intralipid (R). By employing optical frequency modulation on a tunable diode laser, the power spectrum of the heterodyne-detected intensity fluctuations through the dynamic turbid medium is a combination of the time-of-flight distribution and the Doppler p

New rules for the spaces of urbanity.

The best way to conceive semiotical spaces that are not identical to single buildings, such as a cityscape, is to define the place in terms of the activities occurring there. This conception originated in the proxemics of E. T. Hall and was later generalized in the spatial semiotics of Manar Hammad. It can be given a more secure grounding in terms of time geography, which is involved with trajecto

Comparing design processes for the BOP and TOP markets

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. About two-fifths of the world population can be categorized as poor. Poverty is a trap because children born to poor parents are likely to grow up to be poor adults. In recent years, a poverty reduction approach that combines business development with povert

Cysteinyl leukotrienes and their receptors: Bridging inflammation and colorectal cancer.

Long-standing inflammation has emerged as a hallmark of neoplastic transformation of epithelial cells and may be a limiting factor of successful conventional tumor therapies. A complex milieu composed of distinct stromal and immune cells, soluble factors and inflammatory mediators plays a crucial role in supporting and promoting various types of cancers. An augmented inflammatory response can pred

The Experience of GPU Calculations at Lunarc

To meet the ever increasing demand for computational speed and use of ever larger datasets, multi GPU installations look very tempting. Lunarc and the Theoretical Astrophysics group at Lund Observatory collaborate on a pilot project to evaluate and utilize multi-GPU architectures for scientific calculations. Starting with a small workshop in 2009, continued investigations eventually lead to the pr

A literature review of the outcomes after robot-assisted laparoscopic and conventional laparoscopic Nissen fundoplication for gastro-esophageal reflux disease in children.

Robot-assisted surgery is a promising technical innovation. Given the similarities between laparoscopic and robot-assisted surgery it is unlikely that randomized controlled trials would be conducted to disclose any differences between these two technical instruments. Thus, skepticism remains due to lack of any definitive conclusions in the literature.
