Background: Migratory birds play an important part in the spread of parasites, with more or less impact on resident birds. Previous studies focus on the prevalence of parasites, but changes in infection intensity over time have rarely been studied. As infection intensity can be quantified by qPCR, we measured infection intensity during different seasons, which is important for our understanding of

A sports-related concussion (SRC) is most commonly sustained in contact sports, and is defined as a mild traumatic brain injury. An exercise-induced elevation of core body temperature is associated with increased brain temperature that may accelerate secondary injury processes following SRC, and exacerbate the brain injury. In a recent pilot study, acute head-neck cooling of 29 concussed ice hocke

Varje minuts fördröjning av hjärt-lungräddning minskar chansen till överlevnad med 10 procent, skriver åtta forskare vid Centrum för hjärtstopp vid Lunds universitet.Eight researchers at the Lund University Center for Cardiac Arrest write that every minute of delay in cardiopulmonary resuscitation reduces the chance of survival by 10 percent.

Background: Bioactive adrenomedullin (bio-ADM) is a vasoactive peptide with a key role in reducing vascular hyperpermeability and improving endothelial stability during infection, but it also has vasodilatory properties. Bioactive ADM has not been studied in conjunction with acute respiratory distress syndrome (ARDS), but it has recently been shown to correlate with outcomes after severe COVID-19.

This paper describes a general picture of efforts to provide women with equal opportunity both on a national political level, and within academia. A report of recent activities within the newly formed National Division for Women in Physics within the Swedish Physical Society is also given

Background: Physiologically guided revascularization improves clinical outcomes. The cutoff values for deferral with fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are the same across all coronary arteries, despite differences in coronary flow patterns. The objective was to compare deferral rates using either FFR or iFR in the right coronary artery (RCA), left anterior desce

Background: Previous studies suggest an antidepressant effect of omega-3 fatty acids (n-3 PUFAs). This effect may be larger in patients with low-grade inflammation, defined as mild elevations of high sensitivity C-reactive protein or other commonly used inflammatory markers. The antidepressant mechanisms of n-3 PUFAs are not fully understood but may involve modulation of immunometabolic processes

We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret a

Popular Abstract in Swedish De svenska framtidsuttrycken (futuralt presens, futuralt skola och futuralt komma) är alla kontextuellt betingade användningar av uttryck som också har andra funktioner. Syftet med min avhandling är att beskriva vilka kontextvillkor som måste vara uppfyllda för att de tre uttrycken ska fungera som framtidsuttryck. I den modell över svenskans temporala system som presentThe main aim of this study is to specify the contextual conditions that apply to the use of the three central expressions for the future in Swedish: the present form and the auxiliaries skola and komma. A tense suffix indicates a temporal domain and states that a mediating element, here called FIX, is placed in the indicated domain. The present suffix points to a domain that overlaps temporally wi

Generative product design systems used in the context of mass customization are required to generate diverse solutions quickly and reliably without necessitating modification or tuning during use. When such systems are employed to allow for the mass customization of product form, they must be able to handle mass production and engineering constraints that can be time-consuming to evaluate and diff

Psychiatric, physical and biological aspects of posttraumatic stress disorder (PTSD) may be associated with dysfunctions in several cellular processes including nitric oxide (NO) production. NO is synthesized from arginine in a reaction carried out by NO synthase (NOS) enzymes. The recently introduced "global arginine bioavailability ratio" (GABR; ratio of arginine to [ornithine+ citrulline]) has

Background: Roux-en-Y gastric bypass (RYGB) is an effective obesity treatment in adults and has become established in adolescents. Lower adherence to supplementation in adolescents confers a risk for long-term nutritional deficiencies. Objectives: To assess adherence to supplementation, micronutrient intake, and biochemistry in adolescents through 5 years after RYGB. Setting: University hospitals,

We demonstrate the generation and in-situ measurement of the electric field and CEP of intense near-single-cycle laser pulses using the new optical technique of CEP dispersion-scan.
