Testicular development is an androgen-dependent process, and fetal exposure to antiandrogens disrupts male sexual differentiation. A variety of testicular disorders may result from impaired development of fetal Leydig and Sertoli cells. We hypothesized that antiandrogenic exposure during fetal development interferes with desert hedgehog (Dhh) signaling in the testis and results in impaired Leydig

To test the hypothesis that the cerebral amyloid angiopathy (CAA) of Alzheimer's disease (AD) is quantitatively associated with white matter lesions (WML), the brains of 63 demented patients exhibiting varying degrees of Alzheimer encephalopathy (AE) were examined, along with those of 10 nondemented control cases. The ratio of amyloid-positive to amyloid-negative vessels in the leptomeninges of th

Rapporten behandlar utformning av anslutningen mellan yttervägg och platta på mark samt dess inverkan på fukttillståndet i syllar av främst trämaterial. Undersökningen omfattade dels fältmätningar och dels koretiska beräkningar, dessutom gjordes en del laboratorieförsök. Rekommendationer för utformning.

The ovaries of 377 women between the age of 40 and 70 years were measured by ultrasound. About one third of the patients were postmenopausal. Mean value, standard deviation and S.E.M. of the ovarian volume were calculated and related to age, parity and menstrual cycle. Ovarian size decreased with age in all women but bore no relation to parity and day of menstrual cycle in the menstruating group o

We evaluated the incidence and clinical significance of postfracture shortening of the clavicle in 85 patients. There were 71 mid-clavicular fractures and 14 of the lateral end of the clavicle. 46 fractures were primarily undisplaced and 39 displaced. All fractures were nonoperatively treated with sling immobilization. All patients were reexamined 5 years after the fracture. 35 clavicles had heale

Taxa within the Dactylorhiza incarnata/maculata species complex form a diploid and tetraploid complex. The genetic variation revealed by molecular markers indicate that this is a young complex and that polyploidization may be an ongoing process; most, if not all, of the polyploid taxa may have evolved after the last ice age. This conclusion is supported by 1) a close correspondence in general dist

Responses to isotonic quick release of AC-stimulated smooth muscle strips from rabbit urinary bladder were analysed. Releases were performed at the peak of contraction and at a preset tension level in the contraction and relaxation phase. In other expts. responses at 37 degrees C and 27 degrees C were compared. The length response always consisted of 3 parts: (1) elastic recoil, (2) rapid length c

We calculate the cross section for c(c) over bar g -production in diffractive DIS with finite quark masses at zero momentum transfer t. The calculation is done in the leading log(1/x(P)) approximation and is valid in the region of high diffractive masses M (small 3). We apply our cross section formula including both c (c) over bar- and c(c) over bar g in a Monte Carlo simulation to diffractive D*(

Popular Abstract in Swedish Avhandlingen visar två olika vägar för att skapa brukarinflytande, den kollektiv- och den individinriktade vägen. Den kollektiva inriktningen innebär att medborgarna endast kan utöva inflytande via folkvalda företrädare, medan den individinriktade vägen ger möjlighet att samverka direkt med politiker och tjänstemän i den kommunala organisationen. Två olika teorier har aThe dissertation shows two different means or directions for creating civic participation: the collective and the individual way. The collective way is characterized by the citizen's ability to participate only through elected representatives while the individual way makes it possible for inhabitants to participate face to face with politicians and local civil servants. Two different theories hav

BACKGROUND: Self-reported annoyance from electrical equipment has been in evidence since the mid-1980s, and the first reports of illness from everyday chemicals arose in the 1960s. However, the extent of the problem has not yet been fully established.AIMS: The aim of this study was to estimate the prevalence of annoyance related to electrical and chemical factors in a Swedish general population, a

A resonant tunneling permeable base transistor has been realized experimentally by overgrowing a tungsten grating placed in direct vicinity to a double barrier heterostructure. In this way, we can directly modulate the tunneling current via an embedded gate. Since the quality of the overgrown interface is critical, special attention is paid to this issue, and the effect of different wet etchants p

Popular Abstract in Swedish Gangesfloden i Varanasi (Indien) anses samtidigt vara fullkomligt ren och svårt förorenad, beroende på vem som definierar dess egenskaper, brahminska religiösa specialister eller vetenskapligt orienterade miljöaktivister. Medan kontroversen fortgår, försöker några hinduiska religiösa ledare att anpassa sina traditioner till de nya miljöparadigmen, och deras förhållningsWhether the Ganges river in Varanasi (India) is pristinely pure or heavily polluted depends on by whom it qualities are defined, the Brahmin religious specialists in the city or the science oriented environmentalists. While the controversy continues, some Hindu religious leaders are searching for ways to adjust their respective traditions to the environmental paradigms, an initiative that reflects
