A total of 282 renal scintigrams with Tc-99m DMSA in 238 children ranging in age from 10 days to 13 years performed during a 3-year period were reviewed. The authors present 94 kidneys in 85 children in whom no sign of pathology was demonstrated clinically, either by ultrasound or intravenous urography, or by micturating urethrocystography. By exploring homogeneity or heterogeneity of tracer distr

Treatment of Mn-2(CO)(10) with 3,4-toluenedithiol and 1,2-ethanedithiol in the presence of Me(3)NO(.)2H(2)O in CH2CI2 at room temperature afforded the dinuclear complexes Mn-2(CO)(6)(mu-eta(4)-SC6H3(CH3)S-SC6H3(CH3)S) (1), and Mn-2(CO)(6)(mu-eta(4)-SCH2CH2S-SCH2CH2S) (2), respectively. Similar reactions of Re-2(CO)(10) with 3,4-toluenedithiol, 1,2benzenedithiol, and 1,2-ethanedithiol yielded the d

BACKGROUND: Alcohol as a cause of death in middle-aged patients is well-known from clinical studies. A similarly important correlation in the general population of urban middle-aged men is highly underestimated. Health screening investigations have shown that mortality related to alcohol is five times more common in nonparticipants than in participants. From the mid-70s, the Malmoe Screening and I

Windows and the World Wide Web are two of the keys to the IT-explosion that we are all caught up in. Computers can do more and more and are getting easier to use. But how does a blind person handle a graphical environment like Windows? This article deals with Certec’s efforts to find a way to use haptics, i.e. controlling with movements and getting feedback via the sense of touch, to provide new

During the last 50 years, the distribution and abundance of many European butterfly species associated with semi-natural grasslands have declined. This may be the result of deteriorating habitat quality, but habitat loss, resulting in decreasing area and increasing isolation of remaining habitat, is also predicted to result in reduced species richness. To investigate the effects of habitat loss on

In this study we wanted to examine how an adult neuroretina from an animal with an eye similar to the human one survives in vitro. We also wanted to investigate how the culture process affects the adult retina when used in a transplantation paradigm. Full-thickness neuroretinal sheets from adult porcine eyes were dissected into pieces measuring 3 mm in diameter. These were kept in culture for 1-3

The aim of this study was to demonstrate the potential for holographic interferometry to be used for diffusion studies of large molecules in gels. The diffusion and partitioning of BSA (67,000 g/mol) and pullulans (5,900-112,000 g/mol) in agarose gel were investigated. The gel diffusion coefficients obtained for BSA were higher when distilled water was used as a solvent compared to those obtained

OBJECTIVE: To assess the cost-effectiveness of identifying and treating asymptomatic female carriers of Chlamydia trachomatis. DESIGN: Cost-effectiveness analysis based on previously reported cohort analytic studies and average salaries and costs of medical care in Sweden. SETTING: Women attending youth, family planning, and gynecology clinics. PARTICIPANTS: 1000 women and their male sex partners.

The aim of this study was to evaluate the importance of different endogenous and exogenous factors associated with cirrhosis development among hepatitis C virus (HCV)-positive individuals from an area of low prevalence. We studied 106 consecutive HCV RNA positive patients who had undergone liver biopsy. Each patient was assessed with special attention to risk factors for hepatitis C infection, ave

Box jellyfish have the most elaborate sensory system and behavioural repertoire of all cnidarians. Sensory input largely comes from 24 eyes situated on four club-shaped sensory structures, the rhopalia, and behaviour includes obstacle avoidance, light shaft attractance and mating. To process the sensory input and convert it into the appropriate behaviour, the box jellyfish have a central nervous s

By sending a questionnaire (response rate 93%) to 321 women with a history of venous thromboembolism and previous coagulation tests, 72 patients were identified who had a total of 87 pregnancies after the thromboembolic episode. The main aim of the study was to analyze the influence of prophylaxis during pregnancy and delivery on the development of further thromboembolic complications. During preg

BACKGROUND: The aim of the study was to investigate the value of percutaneous fine-needle aspiration cytology (FNAC) in the diagnosis and management of liver tumours. METHODS: FNAC followed by histopathological examination was carried out in 216 patients with suspected liver tumours. The final diagnosis was primary liver cancer in 106, colorectal metastases in 51, non-colorectal metastases in 46,

We investigated how the degree of autotrophy/heterotrophy and organism trophic position influenced the bioaccumulation of polychlorinated biphenyls (PCBs) in 10 benthic river food webs consisting of terrestrial detritus, periphyton, invertebrates, and age-0 brown trout (Salmo trutta) in southern Sweden. Concentrations of PCBs increased with trophic position, estimated from delta(15)N and delta(13)

We report on room-temperature electrical measurements of multibranch junction (MBJ) devices made from a semiconductor heterostructure. We show that the MBJ devices exhibit an interesting electrical property. If the voltage output at one branch is measured as a function of the voltages inputs to all the other branches, the output voltage is determined predominately by the most negative, or the lowe

Possible measures for prevention of neonatal group B streptococcal (GBS) septicemia include active or passiv immunoprophylaxis and administration of penicillin to mothers and infants. In a previous study we have found GBS to be extremely sensitive to chlorhexidine. Furthermore vaginal washing with chlorhexidine diminished the recovery of GBS from parturients. In order to study the effect of chlorh
