We compared menstrual pain, uterine contractility and blood circulation, and plasma concentrations of vasopressin and prostaglandin F(2alpha) metabolite in women with versus without primary dysmenorrhea, and determined the effects of a vasopressin antagonist, 1-deamino-2-D-Tyr(OEt)-4-Thr-8-Orn-oxytocin (Atosiban), on these parameters. Our results do not support the contention that vasopressin is i
The haptophyte Prymnesium parvum is known to produce a set of highly potent exotoxins, commonly called prymnesins. These toxins have been shown to have several biological activities, including ichthyotoxic, neurotoxic, cytotoxic, hepatotoxic and hemolytic activity towards a range of marine organisms. In addition, recent studies have shown that the toxicity of P parvum is enhanced when the cells ar
Implantation of surgical meshes is a common procedure to increase abdominal wall stability in hernia repair. To improve biocompatibility of the implants, sophisticated in vivo animal models are needed to study inflammation and incorporation of biomaterials. Herein, we have established a new model that allows for the quantitative analysis of host tissue response and vascular ingrowth into surgical
Ejection of the genome from the virus, phage, is the initial step in the infection of its host bacterium. In vitro, the ejection depends sensitively on internal pressure within the virus capsid; however, the in vivo effect of internal pressure on infection of bacteria is unknown. Here, we use microfluidics to monitor individual cells and determine the temporal distribution of lysis due to infectio
The study purpose was to evaluate sleep structure following Vagus Nerve Stimulation (VNS) in 15 children with therapy resistant epilepsy and to correlate possible alterations with changes in epileptiform activity and clinical effects. Fifteen children were examined with ambulatory polysomnographic recordings initially, and after 3 and 9 months of VNS-treatment. Sleep parameters, all-night delta po
I den norska författaren Hanne Ørstaviks sjunde roman Prästen från 2004 förflyttas läsaren till Nordens yttersta utposter. Berättarjaget, vid namn Liv, har som en följd av ett tragiskt händelseförlopp avbrutit sina doktorandstudier i systematisk teologi i södra Tyskland. Istället har hon förpassat sig själv till den karga Finnmarken, där hon nu verkar som präst och febrilt brottas med att ge liv å
This paper presents the development of a system dynamic model to simulate and analyze desertification. The human-environment coupled model integrates socio-economic drivers with bio-physical drivers of biomass production, land degradation and desertification. It is based on the UN and GEF definitions of desertification. It illustrates the concept of desertification through differential equation an
Early peat surveys demonstrated the potential to detect Holocene climatic changes in southern Sweden through analysis of the degree of decomposition of Sphagnum peat and motivated systematic collection of peat-strati graphic information during subsequent geological mappings in central and northern Sweden. The resulting (published and unpublished) data was compiled and reanalysed, taking into accou
OBJECTIVE: To investigate long-term sick leave among primary care patients with musculoskeletal disorders and the predictive value of health-status and sense-of-coherence measures. METHODS: Patients aged 17 to 64 years who, during seven weeks, attended one of six primary care centers because of non-traumatic musculoskeletal pain and who completed the SF-36 health questionnaire and the sense of coh
The question "what makes therapy work?" has many facets. For instance, if there is evidence for a certain form of psychotherapy, one must question whether the positive effects are due to its methods or rather to "common factors" that may be shared with a number of other procedures. Second, because all evidence-based forms of psychotherapy represent treatment packages that involve a large number of
Ghrelin is produced by A-like cells (ghrelin cells) in the mucosa of the acid-producing part of the stomach. The mobilization of ghrelin is stimulated by nutritional deficiency and suppressed by nutritional abundance. In an attempt to identify neurotransmitters and regulatory peptides that may contribute to the physiological, nutrient-related regulation of ghrelin secretion, we challenged the ghre
The synthesis and reactivity of the thiophyne and furyne clusters [Ru-3(CO)(7)(mu-dppm)(mu(3)-eta(2)-C4H2E){mu-P(C4H3E)(2)}(mu-H)] (E = S, O) is reported. Addition of P(C4H3E)(3) to [Ru-3(CO)(10)(mu-dppm)] (1) at room temperature in the presence of Me3NO gives simple substitution products [Ru-3(CO)(9)(mu-dppm)-P(C4H3E)(3)}] (E = S, 2; E = O, 3). Mild thermolysis in the presence of further Me3NO af
We tested the hypothesis that controlled hypoxemic resuscitation improves early cerebral metabolic and electrophysiological recovery in hypoxic newborn piglets. Severely hypoxic anesthetized piglets were randomly divided into three resuscitation groups: hypoxemic, 21% O2, and 100% O2 groups (8 in each group). The hypoxemic group was mechanically ventilated with 12-18% O2 adjusted to achieve a cere
During an international breath-hold diving competition, 19 of the participating divers volunteered for the present study, aimed at elucidating possible symptoms and signs of pulmonary edema after deep dives. Measurements included dynamic spirometry and pulse oximetry, and chest auscultation was performed on those with the most severe symptoms. After deep dives (25-75 m), 12 of the divers had signs
To elucidate the role of the gonadotropins in the multiple spawner Atlantic halibut (Hippoglossus hippoglossus) full length cDNAs encoding FSHbeta, LHbeta, and the common alpha-subunit were cloned from pituitary glands by RACE-PCR. The three cDNAs consisted of 614, 595, and 666 nucleotides encoding peptides of 131, 146, and 124 amino acids, respectively. Halibut FSHbeta and LHbeta showed unique st
In this study, the relationships between dietary fat [as measured by serum cholesterol ester fatty acids (CE-FA)], age, smoking, body mass index, and serum lipids were analyzed in 151 subsistence horticulturalists, aged 20-86 yr, from Kitava, Trobriand Islands, Papua New Guinea. Their diet consists of tubers, fruit, coconut, fish, and vegetables with a negligible influence of western food and alco
This article explores to what extent married middle-aged individuals in Europe are governed by the risk of experiencing divorce, when shaping their physical appearance. The main result is that divorce risks, proxied by national divorce rates, are negatively connected to body mass index (BMI) among married individuals but unrelated to BMI among singles. Hence, it seems that married people in societ
The neurohypophysial peptide arginine vasotocin, and its mammalian ortholog arginine vasopressin, influence a wide range of physiological and behavioral responses, including aspects of sexual and social behaviors, osmoregulation, stress response, metabolism, blood pressure, and circadian rhythms. Here, we demonstrate that, in zebrafish (Danio rerio), the vasotocin precursor gene arginine vasotocin
Clinical experience since decades and numerous retro- and, recently, also prospective studies clearly demonstrate that prophylactic treatment, albeit much more expensive, is superior to on-demand treatment regardless if outcome focus on number of joint- or life-threatening bleeds or arthropathy, evaluated by X-ray or MRI, or quality of life measured by general or hemophilia specific instruments. O
