PIP: This study examines the relationship between a history of induced abortion and current or previous sexually transmitted diseases (STDs) and other gynecologic symptoms. Study participants consisted of a cohort of women attending 2 family planning and 1 youth clinic; 192 were admitted with history of induced abortion and 804 women served as controls. A structured interview to obtain data on pre

Two parapatric ecotypes of Silene nutans, exhibiting distinct allozyme patterns, morphology and autecology were investigated for differences in exudation of low molecular weight organic acids from germinating seeds, and for differences in seed phosphorus content. The calcicolous ecotype is restricted to calcareous soils, and the silicicolous one predominantly occurs on acid soils, and sometimes, a

Object. The authors have previously shown that longitudinal sutures without artificial tube support regeneration across a 7-mm gap in the rat sciatic nerve. In the present study, the authors, compared this new approach with the use of autologous nerve grafts across short defects and examined whether the approach could be used to support regeneration across extended gaps and whether the interpositi

PURPOSE: Mutations in the NDP gene give rise to a variety of eye diseases, including classic Norrie disease (ND), X-linked exudative vitreoretinopathy (EVRX), retinal telangiectasis (Coats disease), and advanced retinopathy of prematurity (ROP). The gene product is a cystine-knot-containing extracellular signaling molecule of unknown function. In the current study, gene expression was determined i

In migraine and other primary headaches there is a strong vascular component. Besides the trigeminovascular components some of the associated symptoms point to the involvement of brain stem regions. The central limb of the trigeminal vascular pathway is its projection to the trigeminal nucleus caudalis (TNC) and to the C1-C2 levels of the spinal cord. The aim of the present study was to demonstrat

Cyclic nucleotide phosphodiesterase 3B (PDE3B) has been suggested to be critical for mediating insulin/IGF-1 inhibition of cAMP signaling in adipocytes, liver, and pancreatic beta cells. In Pde3b-KO adipocytes we found decreased adipocyte size, unchanged insulin-stimulated phosphorylation of protein kinase B and activation of glucose uptake, enhanced catecholamine-stimulated lipolysis and insulin-

OBJECTIVE: To determine the prevalence of focally growing lesions in the uterine cavity in women with postmenopausal bleeding and endometrium > or = 5 mm and the extent to which such lesions can be correctly diagnosed by D&C. METHODS: In a prospective study, 105 women with postmenopausal bleeding and endometrium > or = 5 mm at transvaginal ultrasound examination underwent diagnostic hysterosco

Eight children (1--17 yr) underwent bone marrow harvesting while in cytostatic-induced remission of their disease (leukemia [n = 6], Ewing sarcoma, and non-Hodgkin lymphoma). After the induction of general anesthesia, all patients were loaded with 10 mL/kg of a 6% high-molecular dextran solution (Macrodex — Pharmacia), which resulted in a significant preoperative decrease in hematocrit (Hct) from

DNA-dependent protein kinase (DNA-PK) has been shown to take part in cell cycle regulatory signal transduction and in the repair of X-ray-induced DNA double-strand breaks. Functional DNA-PK is furthermore needed for the generation of antigen specificity during lymphocyte maturation. The Ku86 subunit of DNA-PK has been reported to exist in human B lymphocytes in a truncated form capable of binding

This thesis studies the computational complexity and polynomial-time approximability of a number of discrete combinatorial optimization problems involving labeled trees and strings. The problems considered have applications to computational molecular biology, pattern matching, and many other areas of computer science. The thesis is divided into three parts. In the first part, we study some proble

Intestinal alk-SMase (alkaline sphingomyelinase) is an ectoenzyme related to the NPP (nucleotide phosphodiesterase) family. It has five potential N-glycosylation sites and predicated transmembrane domains at both the N- and C-termini. The amino acid residues forming the two metal-binding sites in NPP are conserved, and those of the active core are modified. We examined the functional changes of th

Sorption may affect the bioavailability and biodegradation of pesticides in soils. The aim of this study was to test the effect of surface sorption on microbial utilization of the herbicide glyphosate as a source of phosphorus, nitrogen, or carbon. We added goethite to a humus soil to manipulate the soil's glyphosate sorption capacity. The addition of glyphosate generally either decreased microbia

Streptococcus pyogenes, an important human pathogen, expresses several proteins that interact with the immune system of the host. Among the proteins isolated from different bacterial strains are antiphagocytic M proteins, Ig Fc-binding proteins and exotoxins that act as superantigens. Here we report a novel interaction between S. pyogenes and the human immune system, the ability of most S. pyogene

Background: BARD1 was originally identified as a BRCA1- interacting protein but has also been described in tumour-suppressive functions independent of BRCA1. Several studies have indicated that the BARD1 gene is a potential target for germline changes predisposing to breast and ovarian cancer. The C- terminal Cys557Ser change has previously been uncovered to associate with an increased risk of bre

This article deals with how Swedish welfare authorities, governmental as well as municipal, performed personal case studies during the period 1940 to 1970. The visits at home are focused, as a mean of the authorities to generate truth of the inquired woman. The home visit was part of a personal case inquiry, perhaps initiated from the authorities to create basic data for decision-making. The examp
