Chloroplasts isolated from a plant species, Dimorphotheca pluvialis Moench (Asteraceae), grown under visible light without supplementary UV-B radiation, have poor grana development. The dominant components in the membrane organizations are doublets and triplets of stroma lamellae. However, such chloroplasts possess the capacity for electron transfer through the whole photosynthetic chain, based on

1. Task-dependent modulation of cutaneous input to climbing fibres projecting to the C1, C2 and C3 zones in the cerebellar paravermal lobule V was investigated in awake cats during performance of a reaching task. 2. Climbing fibre responses resulting from low intensity (non-noxious) electrical stimulation of the ipsilateral superficial radial nerve were recorded as extracellular field potentials i

The aim of this project was to investigate possible methods for the concentration of acid hydrolyzate obtained from hydrolyzing wood. A detailed study of concentration of sugar solution by reverse osmosis, RO, has been performed as well as a comparison with mechanical vapor recompression evaporation. The comparison has, in this specific case, shown that RO is currently more expensive. The result i

The first acedemic volume on the history, ideology and social history of Swedish freemasonry. Contains a membership list with 4300 members in Swedish lodges of the 18th century.

Previous results have shown that severe, prolonged hypoglycemia leads to neuronal cell damage in, among other structures, the cerebral cortex and the hippocampus but not the cerebellum. In order to study whether or not this sparing of cerebellar cells is due to preservation of cerebellar energy stores, hypoglycemia of sufficient severity to abolish spontaneous EEG activity was induced for 30 and 6

Serotonin (5-HT) at low concentrations induces an endothelium-dependent relaxation in the rat jugular vein mediated via a 5-HT1-like receptor. The receptor mediating this relaxation was characterized in vitro using agonists and antagonists in segments precontracted with prostaglandin F2 alpha in the presence of the 5-HT2 receptor antagonist ketanserin. The following substances acted as agonists, w

Using laser-Doppler flowmetry during ventriculocisternal perfusion with inulin-[14C]carboxylic acid, choroid plexus blood flow (CPBF) and CSF production were measured simultaneously in rats during periods of 3 h. Blood flow and CSF production decreased only slightly during control experiments. The effect of vasoactive intestinal polypeptide (VIP) was studied at different concentrations of the pept

OBJECTIVE--Steroid hormones, especially estrogens, are known to affect hemostatic risk factors for thromboembolism, cardiovascular disease, and stroke. We examined these risk factors during depression of the serum estradiol concentration by a GnRH analogue. DESIGN--Patients were treated with a GnRH analogue, goserelin (Zoladex), 3.6 mg/inj monthly, for a period of 6 months. Blood samples were coll

The neuropeptide WE-14 is derived from the posttranslational processing of chromogranin A (CgA). While CgA is expressed in a preponderance of neuroendocrine cells, WE-14 is generated in a distinct subpopulation of CgA-immunopositive cells, most notably in the adrenal, pituitary, and parathyroid glands. Physiological and pharmacological studies have demonstrated that CgA is cleaved to generate WE-1

Lifetimes of fine-structure levels in 2s2p3p D-4 and 2s2p3d F-4(o) quartets are calculated in the boron isoelectronic sequence, for C II to F V, using a multiconfiguration Hartree-Fock approach. These quartets are known from earlier experimental and theoretical studies to have different lifetimes for different J-levels, owing to spin-induced transitions, mainly to doublet states in 2s(2)2p and 2s2

The aim of the present study was to characterize the airway effects of U46619, a stable thromboxane A2 mimetic, instilled into the trachea of guinea pigs in vivo, and to investigate the role of different mediators in these effects. The airflow obstruction was evaluated by measurement of airway insufflation pressure (P1) and plasma extravasation by quantification of Evans Blue dye (EBD) in airways.

This article has a threefold purpose. First, it seeks to show how modern rituals among Mi'kmaq traditionalists in eastern Canada are anchored in and derive their rationale from modern reserve existence. Two rituals are described, a kekunit godparent ceremony for a 14-year-old girl and a sweat lodge ceremony later the same evening. Second, the article also provides an example of the paradoxes of "p

The high-resolution Fourier transform infrared spectrum of trans-glyoxal in the gas phase has been recorded in the spectral regions 700-900 cm(-1), 1200-1400 cm(-1), and 1600-1800 cm(-1) with a resolution ranging from 0.0020 to 0.0025 cm(-1). The spectrum displays extensive rotational structures which are assigned to the three fundamental bands upsilon(6) (A(u), 801.5 cm(-1)), upsilon(10) (B-u, 17

During recent decades, research on quality of life has gained increasing interest. In gerontology, the assessment of objective as well as subjective dimensions is recommendable, and the most innovative research will involve the study of the interrelationships of several components. In empirical research objective environmental factors have rarely been explored. The aim of this study was to explore

The photoinduced excited-state processes in 1,1'-diethyl-2,2'-cyanine iodine are investigated using femtosecond time-resolved pump-probe spectroscopy. Using a broad range of probe wavelengths, the relaxation of the initially prepared excited-state wavepacket can be followed down to the sink region. The data directly visualize the directed downhill motion along the torsional reaction coordinate and

Objective: To investigate the effects of cold storage and vinegar addition on glycaemic and insulinaemic responses to a potato meal in healthy subjects. Subjects and setting: A total of 13 healthy subjects volunteered for the study, and the tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden. Experimental design and test meals: The study included four meals; fresh
