Så verkar vi för minskad köttkonsumtion

Forskare har ett särskilt ansvar i klimatfrågan, menar Emma Kritzberg vid Lunds universitet. Hon är en av dem som verkat för vegetariskt som standardval vid biologiska institutionen.

The N680S variant in the follicle-stimulating hormone receptor gene identifies hyperresponders to controlled ovarian stimulation

OBJECTIVE: To study if the follicle-stimulating hormone receptor (FSHR) variant asparagine/serine in amino acid 680 (N680S) can predict hypersensitivity to gonadotropins in women undergoing assisted reproduction.PATIENTS AND METHODS: In this retrospective study, 586 women undergoing their first in-vitro fertilisation treatment were enroled, and their FSHR N680S genetic variant was analysed. The ma

Novel roles of complement in systemic lupus erythematosus - Hypothesis for a pathogenetic vicious circle

We propose that impaired complement function enhances a pathogenetic vicious circle in SLE. In this process, induction and clearance of apoptotic cells is central. Apoptosis could be triggered by various etiological factors, such as infection, UV light, and drug reactions. Clearance of apoptotic material is reduced when complement function is impaired. Apoptosis leads to increased exposure of nucl

Editor's Choice-Is the pre-hospital ECG after out-of-hospital cardiac arrest accurate for the diagnosis of ST-elevation myocardial infarction?

BACKGROUND: Current guidelines recommend that comatose out-of-hospital cardiac arrest patients with ST-segment elevations (STEs) following return of spontaneous circulation (ROSC) should be referred for an acute coronary angiography. We sought to investigate the diagnostic value of the pre-hospital ROSC-ECG in predicting ST-elevation myocardial infarction (STEMI).METHOD: ROSC-ECGs of 145 comatose

KASAM-instrumentets utveckling och psychometriska egenskaper - en översikt.

The Sense of Coherence scale (SOC) is a widely used instrument in medical research as well as in other research areas. The Sense of Coherenceis assumed as a useful concept in assessing an individual’s orientation to life and internal strengths. However, despite the frequent use in vari-ous research studies and several psychometric evaluations there is no unequivocal evidence for its validity and r

Parton Shower Uncertainties with Herwig 7: Benchmarks at Leading Order

We perform a detailed study of the sources of perturbative uncertainty in parton-shower predictions within the Herwig 7 event generator. We benchmark two rather different parton-shower algorithms, based on angular-ordered and dipole-type evolution, against each other. We deliberately choose leading order plus parton shower as the benchmark setting to identify a controllable set of uncertainties. T

Insulin stimulates the uptake of chylomicron remnants in cultured rat hepatocytes

The effects of insulin (10-1000 microU ml-1) on chylomicron remnant uptake and degradation were studied in hepatocyte monolayer cultures. Both uptake and degradation were stimulated by insulin. The degree of stimulation was influenced by cell density, being most pronounced in sparse cultures. The uptake was stimulated in a dose-dependent fashion and was noticed already at a physiological insulin l

Voice evaluation before and after laser excision vs. Radiotherapy of t1a glottic carcinoma

Quality of voice after treatment for T1A glottic squamous cell carcinoma was studied in two matched groups of males treated either with CO2 laser cordectomi (n = 18, mean age 65.2 years) or with full dose radiotherapy (n = 18, mean age 65.1 years). All patients had histologically verified invasive squamous cell carcinoma. Fifteen male patients (mean age 63.9 years) without laryngeal disorders were

Regulation of apolipoprotein A1 synthesis in lymph drained rats

The effect of lymph diversion on plasma apolipoprotein A-I levels was studied. In lymph fistula rats apolipoprotein A-I levels in plasma stayed constant in spite of a loss of an equivalent of one-half plasma pool of apolipoprotein A-I per day through the lymph fistula. This indicates that synthesis of apolipoprotein A-I increases or that catabolism of apolipoprotein A-I decreases in a compensatoryThe effect of lymph diversion on plasma apolipoprotein A-I levels was studied.
