Pyrimidine bases are the central precursors for RNA and DNA, and their intracellular pools are determined by de novo, salvage and catabolic pathways. In eukaryotes, degradation of uracil has been believed to proceed only via the reduction to dihydrouracil. Using a yeast model, Saccharomyces kluyveri, we show that during degradation, uracil is not reduced to dihydrouracil. Six loci, named URC1-6 (f

The Ga(x)In(1-x)Sb ternary system has many interesting material properties, such as high carrier mobilities and a tunable range of bandgaps in the infrared. Here we present the first report on the growth and compositional control of Ga(x)In(1-x)Sb material grown in the form of nanowires from Au seeded nanoparticles by metalorganic vapor phase epitaxy. The composition of the grown Ga(x)In(1-x)Sb na

Elements of family dynamics have been shown to be related to onset, course, as well as prognosis of anorexia nervosa and bulimia nervosa. The goal was to explore the experience of family relations in a group of patients with eating disorders using a projective family test. The Patient group (anorexia=21, bulimia=16), as well as a healthy Control group, were given a projective family test, the Eati

Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc

This article reports on the successful stabilization of the carrier-envelope phase of a 1-kHz laser system that includes a large grating stretcher, a regenerative amplifier, a multipass amplifier and a grating compressor. Phase stability for pulse energies up to 6 mJ is demonstrated using electronic feedback to the oscillator locking electronics as well as feedback via an acousto-optic programmabl

We analyze a similar to 70 ks Chandra Advanced CCD Imaging Spectrometer exposure of the globular cluster omega Cen (NGC 5139). The similar to 17' x 17' field of view fully encompasses three core radii and almost twice the half-mass radius. We detect 180 sources to a limiting flux of similar to 4.3 x 10(-16) erg cm(-2) s(-1) (L-x = 1.2 x 10(30) erg s(-1) at 4.9 kpc). After accounting for the number

This article analyzes the development of the practice for receiving non-Orthodox in Greek Orthodox canon law. The main argument is that the development of this canonical institution was influenced by a pneumatological realist ecclesiology. This historical study of the development of a canonical institution will shed light on how Greek Orthodox canon law has functioned in practice.

Soil phosphorus (P) composition changes with ecosystem development, leading to changes in P bioavailability and ecosystem properties. Little is known, however, about how soil P transformations proceed with ecosystem development in boreal regions. We used 1-dimensional P-31 and 2-dimensional H-1, P-31 correlation nuclear magnetic resonance (NMR) spectroscopy to characterise soil organic P transform

Life expectancy is increasing in most developed countries, in part due to improved socioeconomic conditions and in part to advances in healthcare. It is widely acknowledged that the promotion of healthy ageing by delaying, minimizing or preventing disabilities or diseases is one of the most important public health objectives in this century. In contrast to the menopausal transition in females, we

Background. Although short-term graft survival has improved substantially in renal transplant recipients, long-term graft survival has not improved over the last decades. The lack of knowledge of specific causes and risk factors has hampered improvements in long-term allograft survival. There is an uncertainty if inflammation is associated with late graft loss. Methods. We examined, in a large pro

Pancreatic beta-cells secrete insulin by Ca2+-dependent exocytosis of secretory granules. beta-cell exocytosis involves SNARE (soluble NSF-attachment protein receptor) proteins similar to those controlling neurotransmitter release and depends on the close association of L-type Ca2+ channels and granules. In most cases, the secretory granules fuse individually but there is ultrastructural and bioph

Strategic change, infused with new data, perspectives and concepts may change the inherent meaning of the central tenets in an existing strategy. It taps into the cognitive aspects of a journey where language, in verbal and written form, aids in the process of communicating, understanding and creating new meaning. Hence, it comes as no surprise that communication is argued to be an important means

OBJECTIVE The long-term association between dietary protein and type 2 diabetes incidence is uncertain. We aimed to investigate the association between total, animal, and plant protein intake and the incidence of type 2 diabetes. RESEARCH DESIGN AND METHODS The prospective European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study consists of 12,403 incident typ

Rewetting a dry soil can result in two response patterns of bacterial growth and respiration. In type 1, bacterial growth starts to increase linearly immediately upon rewetting and respiration rates are highest immediately upon rewetting. In type 2, bacterial growth starts to increase exponentially after a lag period with a secondary increase in respiration occurring at the start of the exponentia

Purpose: Flattening filter free (FFF) beams generated by medical linear accelerators have recently started to be used in radiotherapy clinical practice. Such beams present fundamental differences with respect to the standard filter flattened (FF) beams, making the generally used dosimetric parameters and definitions not always viable. The present study will propose possible definitions and suggest

Context Preterm birth is the leading cause of infant mortality in developed countries, but the association between gestational age at birth and mortality in adulthood remains unknown. Objective To examine the association between gestational age at birth and mortality in young adulthood. Design, Setting, and Participants National cohort study of 674 820 individuals born as singletons in Sweden in 1

Preeclampsia (PE) complicates 3-8% of all pregnancies and manifests clinically as hypertension and proteinuria in the second half of gestation. The pathogenesis of PE is not fully understood but recent studies have described the involvement of cell-free fetal hemoglobin (HbF). Hypothesizing that PE is associated with prolonged hemolysis we have studied the response of the cell-free Hb- and heme de
