Eggs of mallard ducks (Anas platyrhynchos) and ring-necked pheasants (Phasianus colchicus) were incubated in clutches arranged to stimulate embryos to hatch earlier or later than normal. This manipulation of hatching time was achieved by combining eggs of different age in the same clutch. To ensure hatching synchrony, embryos communicate with each other during the last stage of incubation, resulti
The right middle cerebral artery was permanently occluded in 12-week-old male spontaneously hypertensive rats. After the surgery the rats were subjected to repeated behavioural tests during the observation period. Fourteen weeks after surgery the fast-twitch extensor digitorum longus (EDL) and the slow-twitch soleus muscle of both sides were removed and examined with regard to muscle fibre charact
The effect of postoperative housing conditions on functional outcome and brain-derived neurotrophic factor (BDNF) gene expression was evaluated 1 month after a distal ligation of the right middle cerebral artery (MCA) in spontaneously hypertensive rats. Two days postoperatively the rats were randomized into four groups; individually housed with no equipment (deprived group), individually housed wi
Two subspecies of Nigella degenii (Ranunculaceae) possess a dimorphism in pollen colour and vary extensively in frequency of the two morphs in natural populations. Here we investigate the role of selection on pollen colour during the pollination phase in the two subspecies and its potential contribution to the maintenance of this colour variation. In a combination of common garden experiments and
Aim. This paper reports a study to investigate coping strategies and sense of coherence in relation to gender, the extent of care, caregiving activities and health-related quality of life in a population-based sample of caregivers aged 75 and over. Background. Caring for another person can be stressful both emotionally, and caregiver burden may affect quality of life in a negative way for the car
The purpose of this study was to investigate the effect of temperature on the release of polycyclic aromatic hydrocarbons (PAHs) from aged contaminated soil. The release of fluorene, phenanthrene, anthracene, fluoranthene and pyrene at 7, 15, 18 and 23 °C was studied using a column leaching method with a hydraulic retention time of 0.5 h. As the temperature declined from 23 to 7 °C the concentrati
Background: To study the impact of social participation, trust and the miniaturisation of community, i.e. high social participation/low trust, on consumption of homemade liquor and smuggled liquor during the past year. Methods: The Scania 2000 public health survey is a cross-sectional, postal questionnaire study. A total of 13,604 persons aged 18–80 years were included. A logistic regression model
Most, but not all, studies have found that women with a high urinary 2-hydroxyestrogen (2OHE) to 16 alpha-hydroxyestrone (16 alpha OHE1) ratio are at reduced risk for breast cancer and have a better prognosis. The aim was to identify factors associated with the pre-operative 2OHE to 16 alpha OHE1 ratio and factors that predicted the change in the ratio between the pre-operative visit and first fol
Background Exposure to metalworking fluid (MWF) aerosols has been shown to be associated with a variety of respiratory and skin diseases of workers. Methods Measurements of particulate aerosols, bacterial bioaerosol, and endotoxins and 3-hydroxy fatty acids (3-OH FAs) content in water-based and straight oil MWFs were done during an 8 hr work shift in the grindery and oil basement sections of a ste
Objective: To delineate the health profile in middle-aged women with cardiovascular disease (CVD). Methods: The Women's Health in the Lund Area (WHILA) project covered all women born 1935 - 1945 ( n = 10,766) living in the Lund area; 6917 (64.2%) women completed a generic questionnaire and underwent physical and laboratory assessments. Of the 6917 women, 6416 were postmenopausal women, of whom 104
Abundance and respiration of free and attached microorganisms were monitored during the decomposition of the seagrass Scirpus maritimus leaves in laboratory microcosms for 30 days. There was a clear succession between bacteria and heterotrophic flagellates during the course of the study. The beginning of the study (1-4 days) was characterized by higher rates of bacterial respiration, compared to t
The ammoxidation of toluene was studied both in presence and absence of gaseous oxygen over MoO3 and in situ prepared Mo4O11 (orth.) and MoO2. Irrespective of the partial pressure of oxygen, total reaction rates decrease in the following order: MoO3 > Mo4O11 > MoO2. The corresponding sequence for the selectivity towards formation of benzonitrile was found to depend on the partial pressure of oxyge
The enzymatic synthesis of PC with decanoic acid in the sn-1 and hexanoic acid in the sn-2 position is described. The procedure comprises the following enzymatic steps: (i) treatment of egg yolk with phospholipase A(2) (PLA(2)) to hydrolyze egg yolk PC to 1-acyl lysophosphaticlylcholine (LPC) (ii) esterification of I-acyl LPC with hexanoic acid catalyzed by PLA(2) to yield PC with hexanoic acid in
Objective: Young adults with childhood-onset GH deficiency (GHD) have reduced memory and attention, which can be improved by treatment with GH. Little information is available on cognitive function in elderly GHD patients. Design: Single center, double-blind, randomized, placebo-controlled study of 52-week duration. Methods: Elderly GH therapy naive GHD patients (n = 34; age range 60-77 years) wer
The electronic properties of the cyclometalated ((CN)-N-and) complexes of iridium and platinum metals with a catechol ligand have been studied experimentally and computationally. The synthesis and characterization of (p-tolylpyridine)Ir(3,5-di-tert-butylcatechol) (abbreviated Ir-sq) and (2,4-diflorophenylpyridine)Pt(3,5-di-tert-butylcatechol) (abbreviated Pt-sq) are reported along with their struc
Within the European Prospective Investigation into Cancer and Nutrition (EPIC), the authors examined the association of ethanol intake at recruitment (1,119 cases) and mean lifelong ethanol intake (887 cases) with lung cancer. Information on baseline and past alcohol consumption, lifetime tobacco smoking, diet, and the anthropometric characteristics of 478,590 participants was collected between 19
