Introduction. In contrast to research findings describing the localization of nitric oxide synthases (NOS), guanylyl cyclases, and cyclic adenosine monophosphate (cAMP)- and cyclic guanosine monophosphate (cGMP)-degrading phosphodiesterase isoenzymes in the human vagina, the distribution of proteins known as major targets for cyclic nucleotides has not yet been evaluated. cAMP- and cGMP-dependent

Retinal ganglion cell (RGC) isodensity maps indicate important regions in an animal's visual field. These maps can also be combined with measures of focal length to estimate the theoretical visual acuity. Here we present the RGC isodensity maps and anatomical spatial resolving power in three budgerigars (Melopsittacus undulatus) and two Bourke's parrots (Neopsephotus bourkii). Because RGCs were st

Studies on the influence of alcohol consumption on lung function have shown conflicting results. Self-reported alcohol consumption may be inaccurate. This study used both a validated alcohol questionnaire and a blood marker of heavy alcohol consumption, and examined potential associations with different lung physiological variables.

This article describes some historical and significant contributions in the field of heat transfer from various Swedish universities and researchers. It also gives an overview of what kind of heat transfer-related research has been going on recently, as well as some current activities. Traditionally, research projects have been associated with the Ph.D. education programs and in these, common thes

Human neurospheres are free-floating spherical clusters generated from a single neural stem cell and comprising cells at different stages of maturation in the neuronal and glial lineages. Although recent findings have disproved the original idea of clonally derived neurospheres according to the paradigm of one stem cell - one neurosphere, they still represent a valid model for growing neural stem

Haemophilia is an X-linked recessive genetic disease of haemostasis. Women carriers may present with a bleeding tendency similar to milder forms of the disease. Haemophilic newborns present risk factors and patterns of bleeding that are challenging. Identification of carriers and genetic counselling before conception is considered optimal to help decide on available conception options and during p

In this paper volume average relations related to the multilevel modeling process in continuum mechanics are analyzed and the concept of average consistency is investigated both analytically and numerically. These volume averages are used in the computational homogenization technique, where a transition of the mechanical properties from the local, microscopic, to the global, macroscopic, length sc

Introduction: The aim of this study was to investigate the role of hand bone mineral density (BMD) loss analyzed with digital X-ray radiogrammetry (DXR) in early rheumatoid arthritis (RA) as a predictor for progression of joint damage. Methods: In 379 patients with early RA, baseline and one-year hand BMD was measured with DXR and the hand bone loss (HBL) was analyzed using the smallest detectable

STUDY QUESTION: What are the diagnostic benefits of using ultrasound in patients with a clinical suspicion of acute salpingitis and signs of pelvic inflammatory disease (PID)? SUMMARY ANSWER: In patients with a clinical suspicion of acute salpingitis, the absence of bilateral adnexal masses at ultrasound decreases the odds of mild-to-severe acute salpingitis about five times, while the presence of

Cardiac resynchronization therapy (CRT) has a well-documented positive effect on mortality and heart failure morbidity. The aim of this study was to assess the long-term survival and the predictive value of self-assessed functional status on the long-term prognosis of patients treated with CRT-pacemaker (CRT-P).METHODS AND RESULTS: Data were retrospectively collected from medical records of 446 co

Haemophilia A severity is closely correlated to the factor VIII (FVIII) activity, which can be measured in different ways. The original one-stage clotting assay is still the most widely used. The two-stage coagulation assay eliminated many of the drawbacks of the one-stage assay and was further developed into the chromogenic assay, a two-staged test with purified coagulation factors in the first s

Simulations of climate over the Last Millennium (850-1850 CE) have been incorporated into the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3). The drivers of climate over this period are chiefly orbital, solar, volcanic, changes in land use/land cover and some variation in greenhouse gas levels. While some of these effects can be easily defined, the reconstructions of sol

Parkinson's disease (PD) is associated with extensive degeneration of dopaminergic neurons originating in the substantia nigra pars compacta, but neuronal loss is also found in the ventral tegmental area (VTA). The VTA projects to areas involved in cognitive and emotional processes, including hippocampus, amygdala, nucleus accumbens and prefrontal cortex, and has thus been proposed to play a role

In this work we demonstrate experimentally the dependence of InSb crystal structure on the ratio of Sb to In atoms at the growth front. Epitaxial InSb wires are grown by a self-seeded particle assisted growth technique on several different III-V substrates. Detailed investigations of growth parameters and post-growth energy dispersive x-ray spectroscopy indicate that the seed particles initially c

Bone and soft tissue sarcomas are a group of histologically heterogeneous and relatively uncommon tumors. To explore their genetic origins, we sequenced the exomes of 13 osteosarcomas, eight myxoid liposarcomas (MLPS), and seven synovial sarcomas (SYN). These tumors had few genetic alterations (median of 10.8). Nevertheless, clear examples of driver gene mutations were observed, including canonica

A fast and simple method for the identification of nonlinear constitutive functions in scalar convection–diffusion equations is presented. No a priori information is needed on the form of the constitutive functions, which are obtained as continuous piecewise affine functions. Accurate and frequent measurements in space and time are required. Synthetic data of batch sedimentation of particles in a

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and adolescents. Alveolar (ARMS) and embryonal (ERMS) histologies predominate, but rare cases are classified as spindle cell/sclerosing (SRMS). For treatment stratification, RMS is further subclassified as fusion-positive (FP-RMS) or fusion-negative (FN-RMS), depending on whether a gene fusion involving PAX3 or PAX7 is prese
