Hunting with firearms decimates primates of large and medium body size (> 2 kg) that disperse the seeds of large-seeded trees. In continuous, un-fragmented forests of southeastern Peru regularly hunted with firearms for 30-40 years, large primates are extirpated and medium-sized (medium) primates are reduced 61% compared with protected forests. At hunted sites seedlings and small juveniles (< 1 m

Copolymers of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with acryamide (AA), N,N-dimethylacrylamide (DMAA), and N-isopropylacrylamide (NIPAM) were found to adsorb on cross-linked agarose gel (Sepharose CL-6B) in the pH range from 7.5-9.2, due to specific boronate-sugar interactions. The molar percentages of phenylboronic acid (PBA) groups in the boronate-containing copolymers (BCCs), as estima

The adsorption and dissociation of carbon monoxide were studied with plane-wave density functional theory on flat Rh(111), stepped and kinked Rh(553), and Ni-decorated Rh(553) surfaces. The theoretical results were compared to high-resolution X-ray photoelectron spectroscopy (HR-XPS) experiments. The most favorable CO adsorption sites for low coverages were identified by a systematic calculation o

Cathelicidins are a family of diverse antimicrobial peptides found in granules of mammalian neutrophils. Cathelicidins are active against a broad range of microbes in different environments. Aside from their antimicrobial activity, cathelicidins possess other biological properties including cytotoxic activity towards mammalian cells. Several studies have shown that the amino acid sequence of cathe

The mobility of mercury (Hg) deposited on soils controls the concentration and toxicity of Hg within soils and in nearby streams and lakes, but has rarely been quantified under field conditions. We studied the in situ partitioning of Hg in the organic top layer (mor) of podsols at two boreal forest sites differing in Hg deposition and climatic regime (S. and N. Sweden, with pollution declining to

The aims of the present study were to assess if MRI gives the same diagnostic information as herniography concerning the presence of hernias and reveals other causes of groin pain. The prospective study enrolled 20 patients referred for herniography, 6 women and 14 men, mean age 48 years. After herniography the patients underwent MRI using T1-weighted, fat-suppressed inversion recovery (STIR), and

A knee injury with anterior cruciate ligament (ACL) rupture may cause deficits in proprioception, increased laxity and decreased muscle strength. Although it may be common knowledge that these factors affect knee function, only a few studies have been performed where this has been investigated in the clinical situation, and the results are not conclusive. The purpose of this study was therefore to

To investigate the Holocene vegetation history and shoreline displacement along the southeastern Swedish coast, two radiocarbon dated pollen, macrofossil and mineral magnetic sequences were studied in the western Blekinge coast: Hunnemara Lake and Smygen Bay. Both pollen records show mosaic vegetation with grasslands, heaths and woodlands prior to 11 300 cal. BP. Pinus-dominated mixed forest was i

Perceived control is of significance in occupational therapy, as revealed in empirical research and suggested in practice models. This study investigated the relationship between perceived control and occupational performance in persons with long-term mental illness. The 177 participants were assessed regarding perceived control (locus of control and self-mastery) and occupational performance (act

A phytochemical investigation of the stem bark of Strychnos scheffleri resulted in the isolation of a new strychnos alkaloid N-a-deacetylmalagashine (1) together with the known derivative malagashine (2). Elucidation of the structures was based mainly on ID and 2D NMR and MS studies and by comparison with related compounds.

The aim of this study was to describe in quantitative terms the effects of ETA and ETB receptor blockade on vascular tone (resistance) in large-bore arterial resistance vessels (> 25 microns), small arterioles (< 25 microns), and veins in the cat gastrocnemius muscle in vivo. In the muscle vascular bed, the combined ETA and ETB receptor antagonist PD145065 (1 mg/kg/min, intra-arterially) abolished

Daily home hemodialysis (HD) patients have a much superior survival rate than patients on regular, 3 times a week in-center HD or on peritoneal dialysis. Present-day HD machines are unsuitable for use at home by patients. We present our concept of the ideal home HD machine that allows daily short and long HD, does all the work preparing for and cleaning up after dialysis, has an intravenous infusi

Previous investigations of hemispheric processes of word perception provide a mixed picture of the sensitivity of each hemisphere to the familiarity of the visual form of lateralized displays. We investigated this issue by presenting words, pseudowords, and nonwords briefly to either the left (LH) or right (RH) hemisphere in lowercase, uppercase, and a matched, unfamiliar mixed-case form, and used

Measurements of the frequency-dependent impedance of a thin wire with ground return is performed. We argue that the results from a downscaled experimental setup are useful and relevant for power-line applications. The experimental result is compared with two categories of line models. The first category is a model that uses fixed line parameters and the second category consists of models where the

Imaginary companions and the characteristics of the children who invent them were explored through interviews. Twenty-six children took part. The first aim was to explore the phenomenon in general, the second to investigate the functions of imaginary companions. General findings concerned the kinds of imaginary companions and some facts about the children who created them. The imaginary companions
