Mitochondrial dysfunction is implicated in amyotrophic lateral sclerosis, where the progressive degeneration of motor neurons results in muscle atrophy, paralysis and death. Abnormalities in both central nervous system and muscle mitochondria have previously been demonstrated in patient samples, indicating systemic disease. In this case-control study, venous blood samples were acquired from 24 amy
Five new species of Caloplaca, C. mallacootensis, C. montenegrensis, C. rexii, C. rossii, and C. subgyalectoides are described, illustrated and compared with closely related taxa.
Silicon (Si) is a key element in global biogeochemical cycling and recent research has shown that changes in the biological component of the Si cycle may lead to more rapid variations in the land-ocean Si transfer than previously thought. The objective of this paper is to better understand the controls on temporal Si dynamics in terrestrial ecosystems, by studying Si fluxes from a small forested c
While collision theory successfully describes the kinetics of chemical reactions, very little is known about the processes at the molecular level, especially if the reacting molecules are large. In this study, using single-molecule spectroscopy, we visually observed that collision between two conjugated polymer (CP) molecules in solution leads to simultaneous rupture of both chains. In addition to
Excessive neutrophil recruitment in the colon is a major feature in acute colitis although the signaling mechanisms behind colonic recruitment of neutrophils remain elusive. Herein, we hypothesized that Rac1 activity might play an important role in neutrophil infiltration in the inflamed colon. Female Balb/c mice were treated with the Rac1 inhibitor NSC23766 (0.5 and 5mg/kg) before and daily after
OBJECTIVE: To study whether the incidence and characteristics of acute mastoiditis in children changed in Sweden following the introduction of new guidelines for diagnosis and treatment of acute otitis media advocating "watchful waiting" as an option in children 2-16 years of age with uncomplicated acute otitis media. METHODS: The records for all patients treated for mastoiditis during 1993-2007 a
We develop and implement an experimental strategy for the generation of high-energy high-order harmonics (HHG) in gases for studies of nonlinear processes in the soft x-ray region. We generate high-order harmonics by focusing a high energy Ti:Sapphire laser into a gas cell filled with argon or neon. The energy per pulse is optimized by an automated control of the multiple parameters that influence
The aim of the study was to make an international comparison of blood levels of cadmium (B-Cd), lead (B-Pb) and mercury (B-Hg) of women in seven European, and three non-European cities, and to identify determinants. About 50 women (age: 46-62) from each city were recruited (totally 480) in 2006-2009. Interview and questionnaire data were obtained. Blood samples were analysed in one laboratory to a
It is suggested that in a localized remnant of Kalahari sand at Dufuya, central Zimbabwe, groundwater flows in an integrated pattern inherited from the paleochannel network of the underlying gneiss. Contact springs occur at discrete localities along the Kalahari sand/gneiss boundary and are associated with spring sapping and land surface subsidence. Subsidence is presumed to be due to preferential
The spectrum of laser-generated acoustic phonons in indium antimonide coated with a thin nickel film has been studied using time-resolved x-ray diffraction. Strain pulses that can be considered to be built up from coherent phonons were generated in the nickel film by absorption of short laser pulses. Acoustic reflections at the Ni-InSb interface leads to interference that strongly modifies the res
This study investigated differences in HPA axis function, measured as salivary cortisol concentrations, between 18 women with chronic trapezius myalgia (MYA) and 30 healthy female controls (CON). In addition, the interactions between HPA axis reactions to psychosocial stress and aspects of pain, health and psychological symptoms were analyzed. Salivary cortisol was measured both in daily life, to
For decades, managers have analysed, planned and implemented long-term brand strategies based on customer mindset metrics (MSMs). Typically, such MSMs are customer satisfaction, liking, brand preference and Net Promoter Score (NPS). One of the core pillars, in brand management literature, is the assumed link between certain customer-based brand assets, often operationalized as MSMs, and future lon
The electrocardiogram (ECG) remains the most immediately accessible and widely used diagnostic tool for guiding emergency treatment strategies. The ECG recorded during acute myocardial ischemia is of diagnostic, therapeutic, and prognostic significance. In patients with myocardial ischemia as a result of decreased blood supply, the initial 12-lead ECG typically shows (1) predominant ST-segment ele
Molecular imprinting is a very powerful synthetic method for preparation of robust materials with pre-designed molecular selectivity. Molecularly imprinted polymers (MIPs) are attractive substitutes for antibodies in many analytical and bioanalytical applications, e.g. for development of biosensors and for drug assays. In addition to selective molecular binding, new functions are being added to MI
With increased longevity and more women becoming centenarians, management of the menopause and postreproductive health is of growing importance as it has the potential to help promote health over several decades. Women have individual needs and the approach needs to be personalised. The position statement provides a short integral guide for all those involved in menopausal health. It covers diagno
Abstract in Undeterminedhe influence of adult foreign-language acquisition on human brain organization is poorly understood. We studied cortical thickness and hippocampal volumes of conscript interpreters before and after three months of intense language studies. Results revealed increases in hippocampus volume and in cortical thickness of the left middle frontal gyrus, inferior frontal gyrus, and
The creative class thesis put forward by Florida [(2002a) The Rise of the Creative Class and How it's transforming Work, Leisure, Community and Everyday Life (New York: Basic Books)] has in recent years been subject to vivid debate and criticism. This article applies the creative class thesis onto a Nordic context in order to examine whether Florida's theory proves fruitful in a context different
