Combined 17alpha-hydroxylase/17,20-lyase defi ciency is a rare, autosomal recessive form of congenital adrenal hyperplasia characterized by the coexistence of hypertension, caused by the hyperproduction of mineralocorticoid precursors and DSD in males and sexual infantilism in females, due to impaired production of sex hormones. Several CYP17 mutations resulting in 17alpha-hydroxylase/17,20-lya...

BACKGROUND The role of chemotherapy in addition to combined endocrine therapy for premenopausal women with endocrine-responsive early breast cancer remains an open question, yet trials designed to answer it have repeatedly failed to adequately accrue. The International Breast Cancer Study Group initiated two concurrent trials in this population: in Premenopausal Endocrine Responsive Chemotherap...

Structural domains are considered as the basic units of protein folding, evolution, function and design. Automatic decomposition of protein structures into structural domains, though after many years of investigation, remains a challenging and unsolved problem. Manual inspection still plays a key role in domain decomposition of a protein structure. We have previously developed a computer progra...

Renal Fanconi syndrome (RFS) refers to the generalized dysfunction of the proximal tubule (PT) (Kleta R. Fanconi or not Fanconi? Lowe syndrome revisited. Clin J Am Soc Nephrol 2008; 3: 1244-1245). In its isolated form, RFS only affects the PT, but not the other nephron segments. The study of isolated RFS can thus provide specific insights into the function of the PT. In a recent paper, Klootwij...

Mycoplasma hyopneumoniae colonizes the swine respiratory tract at the level of ciliated cells by attaching specifically to the cilium membrane. This interaction involves an adhesin called P97; the cilium binding activity of this protein was localized to the carboxy terminus, which included two repeat regions, R1 and R2 (T. Hsu, S. Artiushin, and F. C. Minion, J. Bacteriol. 179:1317-1323, 1997)....

The Kittlitz's Murrelet (Brachyramphus brevirostris) is a rare, non-colonial seabird often associated with tidewater glaciers and a recent candidate for listing under the Endangered Species Act. We estimated abundance of Kittlitz's Murrelets across space and time from at-sea surveys along the coast of Alaska (USA) and then used these data to develop spatial models to describe abundance patterns...

The differential sensitivities to permanganate oxidation of the red and far-red forms of native phytochrome from Avena sativa L. cv Mulaga (isolated as Pfr from red-irradiated tissue) and of partially degraded phytochrome (isolated as Pr from nonirradiated tissue) were determined. The far-red absorbing form of partially degraded phytochrome was 5 times more sensitive than its red-absorbing form...

Oxygen exchange between (18O4)Pi in the medium and water accompanies ATP hydrolysis catalyzed by the calcium-regulated MgATPase of vertebrate skeletal muscle. Exchange was observed in chemically skinned fibers from rabbit psoas muscle held isometrically and activated by 30 microM free Ca2+. The rate of exchange was approximately proportional to Pi concentration (up to 10 mM) and was characteriz...

OBJECTIVE To investigate whether pregnancies with small for gestational age (SGA) neonates, defined as customized birth weight below the 10th centile, are associated with altered levels of metastin in maternal plasma in the first trimester. STUDY DESIGN Maternal blood was obtained between 8 and 14 weeks of pregnancy. Levels of metastin were measured in pregnancies with (n = 31) or without SGA...
