The influence of subphase characteristics (ionic strength, pH, and the presence of bridging cations) on the conformation and lateral orientation of the hydrophobic polypeptide poly-(L)-leucine (p-leu) has been investigated at the air-water interface with the surface film balance technique as well as with Brewster angle microscopy (BAM). In addition, Langmuir-Blodgett films of p-leu deposited on qu

Objective: To examine nicotine use and its correlates among psychotic patients. Method: Longitudinal naturalistic study of 176 patients, diagnosed with schizophrenia or schizophrenia-related psychotic disorders, and treated with risperidone at study entry. Levels of nicotine use (smoking, snuffing) were measured along with other relevant ratings and measurements (symptoms, drug treatment, side eff

Registered nurses' lived experience of preceptorship was studied in this phenomenological study. To illuminate the meaning of registered nurses' experience of being a preceptor for student nurses, individual tape-recorded interviews were conducted with 17 registered nurses. They narrated their experience of being a personal preceptor for student nurses during practical training on a hospital unit,

In order to study the effect of heparin in inducing osteoporosis, 30 female rats were divided in two groups and treated with daily injections of 2 IU heparin/g body weight for 33 and 65 days and compared with the same number of rats acting as controls. The mineral bone mass in the femora of the animals was measured quantitatively. A significant (p less than 0.001) reduction in bone mineral mass wa

In this paper, the Ge overgrowth of oxidized and reduced Ge/Si islands is studied. The islands were grown in a hotwall ultrahigh vacuum chemical vapour deposition reactor. The oxidation was performed in air at room temperature and the reduction in a hydrogen atmosphere at 600degreesC. After reduction, Ge was deposited at the same temperature. The results of the overgrowth show that the reduced nat

Thirty rats were subjected to a standardized critical aortic injury and divided into six groups. In addition to controls, the animals were treated with a pneumatic antishock garment (PASG), massive intravenous or intra-aortic saline infusion, or PASG in combination with either massive intravenous or intra-aortic saline infusion. Twenty-six rats were subjected to a standardized hepatic injury and d

Research within nursing and medicine is moving at an increasing pace. This makes it difficult for the staff - involved with medical care to find the right path through all the new research and development. Working according to evidencebased procedures within both medicine and nursing means using in one’s work the recommendations which have been based on literature studies that have compiled, revie

The relationships between abdominal and pelvic fat compartments and glucose and lipid metabolism were investigated in early postmenopausal women. Fifty-five healthy, postmenopausal women aged 52-53 yr participated in the study. Fat distribution (intra-abdominal and sc abdominal fat, and intrapelvic and sc pelvic fat) was estimated by computed tomography. Insulin sensitivity was assessed by euglyce

Popular Abstract in Swedish En simuleringsmodell, FARMFLOW, utvecklades för att beräkna förråd, flöden och balanser av fosfor (P), zink (Zn) och kadmium (Cd) på mjölkgårdar. De simulerade kontinuerliga förändringarna av ämnesförråden gör det möjligt att utvärdera de långsiktiga effekterna av olika skötselstrategier. Fältdata från en svensk försöksgård, Öjebyn, användes för att parameterisera FARMFA simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. The FARMFLOW model reproduces feedback mechanisms of the internal cyclin

Sedimentological and morphological changes on the upper and lower shoreface during relatively stable sea-level highstand conditions have been investigated in the Pomeranian Bight, southern Baltic Sea, at time scales ranging from storm events to millennia. In order to cover that variety of time scales, different methods have been applied. Seasonal variations in the morphology of the upper shoreface

Release of cytotoxic granule proteins from activated eosinophil granules is considered to be a key pathogenic mechanism in eosinophilic diseases. Degenerated eosinophils and extracellular eosinophil granules have been repeatedly depicted. The present overview describes evidence that eosinophil lysis and distribution of free eosinophil granules (as opposed to 'classical degranulation') is an import
