The reproductive organs of conifers, the pollen cones and seed cones, differ in morphology from the angiosperm flower in several fundamental respects. In this report we present evidence to suggest that the two plant groups, in spite of these morphological differences and the long evolutionary distance between them, share important features in regulating the development of the reproductive organs.

BACKGROUND: Hormone-sensitive lipase (HSL) is a key enzyme in the mobilization of fatty acids from stored triacylglycerols. Its activity is regulated by reversible protein phosphorylation. In rat HSL Ser563, Ser659 and Ser660 have been shown to be phosphorylated by protein kinase A (PKA) in vitro as well as in vivo. METHODOLOGY/PRINCIPAL FINDINGS: In this study we employed site-directed mutagenesi

BACKGROUND: Childhood pre-B acute lymphoblastic leukemia (ALL) is a bone marrow (BM) derived disease, which often disseminates out of the BM cavity, where malignant cells to a variable degree can be found circulating in the peripheral blood (PB). Normal pre-B cells are absolutely dependent on BM stroma for survival and differentiation. It is not known whether transformed pre-B ALL cells retain any

Met care demands are key aspects in poststroke quality of care. This study aimed to identify baseline predictors and 12-month factors that were associated with perceived unmet rehabilitation needs 1 year poststroke.

Context: Arginine vasopressin (AVP) is known to affect liver glycogenolysis, insulin, and glucagon secretion and pituitary ACTH release. We previously showed that high copeptin, the stable C-terminal fragment of AVP prohormone, is independently associated with hyperinsulinemia and future development of diabetes mellitus. Objective: The objective of the study was to examine whether plasma copeptin

In the light of a new registration of all apsidal churches in Scandinavia (1,222 in all), the author discusses the occurrence and frequency of apses, and puts forward the hypothesis that the apse symbolizes the seat of the bishop.

Anticoagulation treatment is effective in preventing both death and recurrence in patients with venous thromboembolism (VTE), but at the same time confers a substantial risk of bleeding complications. The aim of this study was to examine the rate of and predictors for bleeding complications in VTE patients on warfarin with high treatment quality. In total 13,859 patients on warfarin for VTE betwee

The success of the IEEE 802.11 standard has prompted research into efficiency of the different medium access methods and their support for different traffic types. A modified version of the point coordination function (PCF) called modified PCF has been introduced as a way to improve the efficiency over the standard method. It has been shown through a simulation study and a mathematical analysis th

Förslag på hur man skall kunna arbeta effektivt vid beskrivning, produktion och dokumentation av datorstyrda klimatanläggningar genom att beskriva anläggningens funktion med ett högnivåspråk. Beskrivs med ett exempel.

Overwash, the flow of water and sediment over the crest of a beach, contributes to flooding and the deposition of sand landward of the beach crest. Washover, the sand deposited by overwash, contributes to the sediment budget and migration of barrier islands. The ability to predict the occurrence, location, and thickness of overwash deposits is important for coastal residents, coastal town planners

Vid nya Barnkliniken, Universitetssjukhuset i Lund provades fuktprofil och emissioner samtidigt i full skala på golvsystem med högaktuella material såsom linoleum, PVC- och gummimatta. Emissionsmätningarna utfördes vid Statens Provnings- och Forskningsinstitut, Borås medan fukt mättes vid LTH Byggnadsmaterial, Lund, 1999-2000. Provningsresultatet visar att det just nu saknas relevanta alternativ t
