Introduction: Elevated pulmonary vascular resistance (PVR) is observed in both physiological and pathological states. Pulmonary hypertension (PH) is a condition associated with significant morbidity and mortality in neonates and children and curative pharmacotherapy is lacking in most cases. In utero, a high PVR allows for blood to bypass the lungs through the open ductus arteriosus (DA). Vascular

Although prior falls are a well-established predictor of future fracture, there is currently limited evidence regarding the specific value of falls history in fracture risk assessment relative to that of other clinical risk factors and bone mineral density (BMD) measurement. We therefore investigated, across the three Osteoporotic Fractures in Men (MrOS) Study cohorts, whether past falls predicted

Groundwater is the general source of drinking water in the Shimabara Peninsula, Nagasaki, Japan, and consequently, occurring nitrate nitrogen (NO3-N) pollution in the groundwater is a significant problem. Although various countermeasures have been implemented, nitrate nitrogen concentrations remain serious. Therefore, it is necessary to evaluate effects of different potentially effective counterme

Background: Carry Life UF is a novel peritoneal dialysis (PD) technology for improved fluid management using steady concentration PD (SCPD). The Carry Life UF treatment starts with a manual peritoneal fill of 1.36% glucose PD fluid, followed by a 5-hour treatment where small amounts of glucose are continuously added to maintain a stable intraperitoneal glucose concentration. A recent in-center cli

Bakgrund: Den kurativa behandlingen för resektabla lokalt avancerade stadier av cancer i munhålan innefattar i regel en kombination av kirurgi och radioterapi (RT). Huruvida RT bör ges först och därefter följas av kirurgi, eller om tumören bör opereras bort först, följt av RT postoperativt, har dock inte studerats i någon större omfattning.Syfte: Denna avhandling undersöker olika aspekter av pre- Background: The curatively intended treatment for resectable locally advanced stages of oral cavity cancer (OCC) generally involves a combination of surgery and radiotherapy (RT). However, whether to apply RT first and then proceed with surgery, or to resect the cancer and subsequently administer RT, has not been extensively studied. Aims: This thesis examines various aspects of pre- versus postop

Fine-grained windblown deposits, known as loess, in which fossil soils (palaeosols) are preserved, serve as excellent records of past climate. However, paleoclimate reconstruction studies on loess-palaeosol sequences (LPS) in Southeastern Europe have primarily focused on climate changes during the last one or two glacial-interglacial cycles. Surprisingly, little attention has been given to the cli

In 1997 Tetra Brik Packaging Systems (TBPS) introduced the Prisma family into the portfolio. The family, which contains four volumes: X ml, 330 ml, 1000 ml and 2000 ml, is characterised by having eight panels at mid height. The new shape of the packages has forced TBPS to make modifications in the equipment and alterations in the distribution chain, from producers to consumers. This master's

Concerns regarding environmental issues have led to increasing efforts for investigating sustainable production routes for the future industry that is based on renewable resources. Among the biobased chemicals, the C3-chemicals 3-hydroxypropionaldehyde (3-HPA), 1,3-propanediol (1,3-PDO) and 3-hydroxypropionic acid (3-HP), have been identified as top candidates for the chemical industry. Lactobacil

Context. Streaming instability is a key mechanism in planet formation, clustering pebbles into planetesimals with the help of self-gravity. It is triggered at a particular disk location where the local volume density of solids exceeds that of the gas. After their formation, planetesimals can grow into protoplanets by feeding from other planetesimals in the birth ring as well as by accreting inward

Changes in the latitudinal position and strength of the Southern Hemisphere westerlies (SHW) are thought to be tightly coupled to important climate processes, such as cross-equatorial heat fluxes, Atlantic Meridional Overturning Circulation (AMOC), the bipolar seesaw, Southern Ocean ventilation and atmospheric CO2 levels. However, many un

Most pathogens can infect a number of different host species, but host species often differ considerably in susceptibility to a given pathogen. In the case of zoonotic pathogens, natural hosts typically present little or no disease symptoms, while humans and other “spill-over” hosts often present severe symptoms. Differences in susceptibility do not only occur between natural and non-natural hosts

Objective: To describe the clinical and ultrasound characteristics of ovarian pure clear cell carcinoma. Methods: This was a retrospective study involving data from 11 ultrasound centers. From the International Ovarian Tumor Analysis (IOTA) database, 105 patients who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 1999 and 2016 were identified with a

This research focuses on the contemporary case study of the Thawra Chronicles, founded by three London-based members of the Lebanese diaspora in the wake of the Lebanese Revolution in early October 2019 to support the social movement from afar, targeting non-Lebanese individuals as well as Lebanese within and beyond its borders. Thawra Chronicles is a multifaceted, independent alternative online o

PurposeThe benefit of adding concurrent systemic therapy to definitive radiation therapy (RT) for patients with T1-2 oropharyngeal squamous cell carcinoma (OPSCC) and limited neck node involvement is uncertain. This study investigates whether chemotherapy (CRT) in patients with early-stage (T1-2) low-volume nodal disease (Union for International Cancer Control Seventh Edition N1-2b) improves overa

Northern Europe was capped by ice during Weichsel (Wurm), the maximum of which occurred approximately 18,000 years before present. When in the latter part of the 19(th) century the view of an all-devastating land ice (the tabula rasa hypothesis) was generally adopted by natural scientists, plant biogeographers used a simple model predicting a post-glacial, northwards re-migration of species in con

Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. The surface associated M protein of Streptococcus pyogenes, a common human pathogen, exhibits antigenic variation due to an N-te

Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. Sandy coasts are dynamic systems. Thus, risk assessments and coastal manage
