Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

PURPOSE: We evaluated unmet needs of lower urinary tract symptoms-benign prostatic enlargement pharmacological treatment by measuring symptom improvement, persistence and deterioration in real life. A prospective registry was conducted for 24 months in 5 European countries and analyzed by the European Association of Urology Research Foundation. MATERIALS AND METHODS: Previously untreated and treat

Allergic rhinitis is an inflammation in the nose caused by overreaction of the immune system to allergens in the air. Managing allergic rhinitis symptoms is challenging and requires timely intervention. The following are major questions often posed by those with allergic rhinitis: How should I prepare for the forthcoming season? How will the season's severity develop over the years? No country yet

The El Niño - Southern Oscillation (ENSO) influences the global climate and the variability in the terrestrial carbon cycle on interannual timescales. Two different expressions of El Niño have recently been identified: (i) central Pacific (CP) and (ii) eastern Pacific (EP). Both types of El Niño are characterised by above-average sea surface temperature anomalies at the respective locations. Studi

A new setup for burning velocity measurements of liquid fuels at elevated pressures using the Heat Flux method has been constructed. The burner design has been improved comparing to previous studies in this and other laboratories. Laminar burning velocities were determined experimentally for ethanol+air and methanol+air mixtures over a range of conditions including equivalence ratio (0.8 to 1.3),

Wave climate data for the Swedish provinces Skane and Halland, were hindcast using SWAN, a third-generation spectral wave model. The 40-year wave dataset, from 1979 to 2019, is made available through an open-access data portal (https://gis.sgi.se/vagmodell/). The wave data has a three-hour resolution and includes significant wave height, peak wave period, and wave direction. The wave model domain

Semialgebraic proof systems have been studied extensively in proof complexity since the late 1990s to understand the power of Gröbner basis computations, linear and semidefinite programming hierarchies, and other methods. Such proof systems are defined alternately with only the original variables of the problem and with special formal variables for positive and negative literals, but there seems t

We study the organic aerosol (OA) budget in a tropical forest by analyzing a case that is representative for the OP3 campaign at Borneo. A model is designed that combines the essential dynamical and chemical processes that drive the diurnal evolution of reactants in the atmospheric boundary layer (BL). In this way, the model simultaneously represents the effects and interactions of various dynamic

Atopic dermatitis (AD) is a highly pruritic, chronic inflammatory skin disease. The diagnosis is made using evaluated clinical criteria. Disease activity and burden are best measured with a composite score, assessing both objective and subjective symptoms, such as SCORing Atopic Dermatitis (SCORAD). AD management must take into account clinical and pathogenic variabilities, the patient’s age and a

We establish an exactly tight relation between reversible pebblings of graphs and Nullstellensatz refutations of pebbling formulas, showing that a graph G can be reversibly pebbled in time t and space s if and only if there is a Nullstellensatz refutation of the pebbling formula over G in size t + 1 and degree s (independently of the field in which the Nullstellensatz refutation is made). We use t

This paper applies an analytical method for developing policy strategies to optimize municipal waste management systems (MWMSs) to the case of the Land of Fires (LoF). The LoF is an area of Italy’s Campania region that is characterized by a legacy of authoritarian environmental governance and the improper dumping and burning of waste. In this paper, we employ the fuzzy cognitive maps (FCM) method,

Motion-event typology has moved into a “post-Talmian” terrain of approaches focusing on an open-ended number of patterns across languages and construc- tions. Following a proposal to distinguish between four typological clusters, we systematically compared the motion event descriptions in four languages suggested to exemplify these clusters: Swedish, French, Thai and Telugu, with the help of an el

A persistent controversy in language evolution research has been whether language emerged in the gestural-visual or in the vocal-auditory modality. A "dialectic" solution to this age-old debate has now been gaining ground: language was fully multimodal from the start, and remains so to this day. In this paper, we show this solution to be too simplistic and outline a more specific theoretical propo

Lateralization is a fundamental property of the human brain that affects perceptual, motor, and cognitive processes. It is now acknowledged that left-right laterality is widespread across vertebrates and even some invertebrates such as fruit flies and bees. Honeybees, which learn to associate an odorant (the conditioned stimulus, CS) with sucrose solution (the unconditioned stimulus, US), recall t

Only recently, d-amino acids have been identified in mammals. Of these, d-serine has been most extensively studied. d-Serine was found to play an important role as a neurotransmitter in the human central nervous system (CNS) by binding to the N-methyl-d-aspartate receptor (NMDAr), similar to glycine. Therefore, d-serine may well play a role in all physiological and pathological processes in which

Deficiency of subunit 6 of the conserved oligomeric Golgi (COG6) complex causes a new combined N-and O-glycosylation deficiency of the congenital disorders of glycosylation, designated as CDG-IIL (COG6-CDG). The index patient presented with a severe neurologic disease characterized by vitamin K deficiency, vomiting, intractable focal seizures, intracranial bleedings and fatal outcome in early infa

Three-phosphoglycerate dehydrogenase (3- PGDH) deficiency is a rare recessive inborn error in the biosynthesis of the amino acid L-serine characterized clinically by congenital microcephaly, psychomotor retardation, and intractable seizures. The biochemical abnormalities associated with this disorder are low concentrations of L-serine, D-serine, and glycine in cerebrospinal fluid (CSF). Only two m

A growing number of inherited disorders causing severe and progressive neurological deficits are linked to peroxisomal dysfunction. More than 15 peroxisomal diseases with neurological manifestations and some of them with dysmorphic features are identified. The diseases are classified into three groups depending on some similarities in the pathophysiology of the diseases within each group: defectiv
