BACKGROUND: The aim of this study was to analyse the effects of an estradiol (E2)–progesterone substitution protocol on the endometrial expression of estrogen-sensitive genes during the peri-implantation period. METHODS: Peripheral blood and endometrial biopsies were obtained from 13 infertile women both in a natural cycle (NC), on days 5 and 7 after ovulation (NC5, NC7), and in an artificial (sub

Children spend a large percentage of their day with their classmates in school. Classmates are not only co-workers, but also individuals interacting socially as friends. The understanding of group affiliation and friendship interaction in school is of great importance to social work in school because of its implications on children’s wellbeing and academic performance. Several studies show that so

Xylose forms the direct carbohydrate-protein link in extra- or pericellular proteoglycans (PGs) that are substituted with either chondroitin sulfate (CS)/dermatan sulfate (DS) and/or heparan sulfate (HS). Cell surface PGs carrying HS are important regulators of cell growth. Xylose coupled to an aromatic compound can enter cells and initiate either CS/DS synthesis or both HS and CS/DS synthesis, de

Background: Septic arthritis (SA) after anterior cruciate ligament reconstruction (ACLR) is a rare yet severe complication. The samples in previous studies have been small and without nationwide coverage, making analysis uncertain with a risk of bias. Conclusions to recommend preventive measures are therefore difficult to draw, and it has not been possible to perform a comprehensive risk factor an

Diamond–Blackfan anemia (DBA) results from haploinsufficiency of ribosomal protein subunits in hematopoietic progenitors in the earliest stages of committed erythropoiesis. Nemo-like kinase (NLK) is chronically hyperactivated in committed erythroid progenitors and precursors in multiple human and murine models of DBA. Inhibition of NLK activity and suppression of NLK expression both improve erythr

Chondrules in primitive meteorites likely formed by recrystallisation of dust aggregates that were flash-heated to nearly complete melting. Chondrules may represent the building blocks of rocky planetesimals and protoplanets in the inner regions of protoplanetary discs, but the source of ubiquitous thermal processing of their dust aggregate precursors remains elusive. Here we demonstrate that esca

In this paper, design and measurements of a fully integrated power amplifier (PA) are presented. The PA consists of two amplifying chains each having a driver and a power stage. A low loss on chip power combiner combines the outputs from two amplifying chains, and also performs impedance transformation and differential to single-ended conversion. To linearize the PA, the driver stage is biased in

The 17 UN Sustainable Development Goals (SDGs) provide a framework for “peace and prosperity for people and the planet, now and into the future” (UN, 2015). Fast-moving societal questions as the ones related to the SDGs are often addressed from within traditional disciplinary research paradigms, which might not be best equipped for tackling the emerging challenges. At Lund University, an interdisc

The aim of this thesis is to explore what impacts the IDF’s Military Orders regarding water have on Palestinians in the West Bank, taking international humanitarian law (IHL) and International Convention on Civil and Political Rights (ICCPR) into consideration. Thus, to discover whether or not Israel’s actions are compatible with IHL and treats everyone equal before the law, as stated in ICCPR Art
