Chick cDNA clones for a new member of the FACIT (fibril-associated collagens with interrupted triple helices) subfamily have been isolated and sequenced. The collagen chain encoded by these cDNAs was assigned the next consecutive number, making it the alpha1(XX) collagen chain. Assignment of type XX collagen to the FACIT family was based on sequence similarities to types XII and XIV collagen. T...

Blow-up phenomena are analyzed for both the delay-differential equation (DDE) u(t) = B(t)u(t− τ), and the associated parabolic PDE (PDDE) ∂tu = ∆u+B (t)u(t− τ, x), where B : [0, τ ] → R is a positive L function which behaves like 1/ |t− t∗| , for some α ∈ (0, 1) and t∗ ∈ (0, τ). Here B′ represents its distributional derivative. For initial functions satisfying u(t∗ − τ) > 0, blow up takes place...

BACKGROUND SOX9 is a widely expressed transcription factor playing several relevant functions during development and essential for testes differentiation. It is considered to be the direct target gene of the protein encoded by SRY and its overexpression in an XX murine gonad can lead to male development in the absence of Sry. Recently, a family was reported with a 178 kb duplication in the gene...

Differentiation of mouse embryonic germ cells as male or female is dependent on the somatic environment of the gonad rather than the sex chromosome constitution of the germ cell. However, little is known about the initiation of germ cell sexual differentiation. Here, we traced the initiation of germ cell sexual differentiation in XX gonads using the Stra8 gene, which we demonstrate is an early ...

BACKGROUND AND AIMS Chronic obstructive pulmonary disease (COPD) is currently the 5th cause of morbidity and mortality in the developed world and represents a substantial economic and social burden. The aim of this study is to report on hospital admissions and related costs of hospital treatment for COPD in the Puglia Region of Italy in the years 2005-2007. MATERIALS AND METHODS Patients were...

The diagonal component ␧ xx and off-diagonal component ␧ xy of the complex dielectric tensor for the ferromagnetic compound NiMnSb are determined using ex situ spectroscopic ellipsometry and magneto-optic analysis over the spectral range from 0.7 to 6.2 eV. The effects of the overcoat on the raw data are removed by the analysis. First, the complex ␧ xx of thin-film NiMnSb were determined by ex ...

In this study, we aimed to investigate the influence of ACTN3 R577X gene polymorphism on muscle damage responses in athletes competing in an ultra-endurance race. Twenty moderate to well-trained ultra-runners who had entered in an official 37.1 km adventure race (22.1 km mountain biking, 10.9 km trekking, 4.1 km water trekking, 30 m rope course, and orienteering) volunteered for the study. Bloo...

In this paper, we consider a set of HTTP flows using TCP over a common drop-tail link to download files. After each download, a flow waits for a random think time before requesting the download of another file, whose size is also random. When a flow is active its throughput is increasing with time according to the additive increase rule, but if it suffers losses created when the total transmiss...

  Poverty is a multi-dimensional problem and various researchers, based on their field, have investigated different aspects of poverty. Moreover, poverty, as a global problem, could be an interesting subject for both developed and developing countries. In recent decades, both international org...
