The composition of the egg parasitoid guild of the golden egg bug, Phyllomorpha laciniata, in Spain

The golden egg bug (Phyllomorpha laciniata (Villers)) is a phytophagous insectwith an unusual reproductive system. Females use the bodies of conspecifics,bothmales and females, as oviposition substrates. In addition, a varying fractionof the eggs is laid on the food plant. Egg carrying on conspecifics increases offspring survival. Predators and, especially, hymenopteran parasitoids are the main ca

Polymorphism in the oxytocin promoter region in patients with lactase non-persistence is not related to symptoms.

BACKGROUND: Oxytocin and the oxytocin receptor have been demonstrated in the gastrointestinal (GI) tract and have been shown to exert physiological effects on gut motility. The role for oxytocin in the pathophysiology of GI complaints is unknown. The aim of this study was to examine genetic variations or polymorphism of oxytocin (OXT) and its receptor (OXTR) genes in patients with GI complaints wi

Gösta Werners Midvinterblot och fyrtiotalets experimentfilmskultur

Även om Gösta Werner (1908-2009) aldrig var någon centralgestalt inom den svenska experimentfilmen, likt Pontus Hultén eller Peter Weiss, gjorde han starkt avtryck litegrann från sidan. Under närmare nio decennier närde Werner en självreflexiv inställning till filmmediet i rollen som filmstudioordförande, redaktör, filmskapare, föreningsman och forskare och det är i synnerhet bredden på hans engag

Inhibition of MEK5 by BIX02188 induces apoptosis in cells expressing the oncogenic mutant FLT3-ITD.

Fms-like tyrosine kinase-3 (FLT3) is a growth factor receptor normally expressed on hematopoietic progenitor cells. Approximately one third of all patients with AML carry an activating mutation in FLT3 that drives proliferation and survival of the leukemic cells. The most common activating mutation is the so-called internal tandem duplication (ITD), which involves an in-frame duplication of a segm

Risk factors for medial meniscal pathology on knee MRI in older US adults: a multicentre prospective cohort study.

OBJECTIVES: Meniscal pathology in which the aetiology is often unclear is a frequent finding on knee MRI. This study investigates potential risk factors for medial meniscal lesions or extrusion in middle-aged and elderly persons. METHODS: Prospective cohort study using population-based subjects from Birmingham, Alabama and Iowa City, Iowa, USA (the Multicenter Osteoarthritis Study). 644 men and

Location of metastases in cancer of unknown primary are not random and signal familial clustering.

Cancer of unknown primary (CUP) is a fatal disease diagnosed through metastases. It shows intriguing familial clustering with certain defined primary cancers. Here we examine whether metastatic location in CUP patients is related to primary non-CUP cancers in relatives based on the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for CUP patients defined by metastatic

Robust Multichannel Detection of Mixtures Using Nuclear Quadrupole Resonance'

Nuclear quadrupole resonance (NQR) is a radio-frequency (RF) spectroscopic technique, able to detect the presence of many high explosives and narcotics. In practice, the weak NQR signal is often corrupted by strong RF interference (RFI); therefore, various multichannel detection algorithms have recently been proposed for NQR. However, these algorithms allow for only a single compound/polymorph, wh

Biomarkers of early chronic obstructive pulmonary disease (COPD) in smokers and former smokers. Protocol of a longitudinal study.

Chronic obstructive pulmonary disease (COPD) is an irreversible disease, diagnosed predominantly in smokers. COPD is currently the third leading cause of death worldwide. Far more than 15 % of smokers get COPD: in fact, most develop some amount of pulmonary impairment. Smoking-related COPD is associated with both acute exacerbations and is closely correlated to comorbidities, such as cardiovascula
