"Goodbye Dolly?" The ethics of human cloning

A randomized controlled study was carried out to assess the efficacy of a single dose of benzathine penicillin for treating children 2-12 years old with presumed S. pneumoniae pneumonia. One-hundred-and-seventy-six children screened at self-referral pediatric emergency services in Belo Horizonte, Brazil, were randomized to only one injection of benzathine penicillin (n = 93, case-group) or a 7-day procaine penicillin regimen (n = 83, control-group), upon diagnosis of pneumococcal pneumonia based on clinical and radiological characteristics. Follow-up was carried out on the second day after treatment and around the 7th and/or 14th day after treatment allocation. No statistical significant difference was found for sociodemographic, clinical, laboratory or radiographic characteristics among the two groups. Evident or total radiographic clearing was demonstrated for 92.3 and 95.1 per cent of the benzathine penicillin and procaine penicillin groups, respectively (P = 0.54). Benzathine penicillin may be considered an alternative to classic regimens for treating pneumonia due to sensitive strains of S. pneumoniae among children 2-12 years old. Other benefits are its lower cost, better compliance and low rates of adverse reactions.

After a child's parent has died

In this preliminary study the author sought to ascertain some understanding of variability in surviving parents' and children's perceptions of family closeness, communication, and of the child's experience following the death of a parent. Data collected in interviews and from the Kvebaeck Family Sculpture Test suggest that not only do parents and children differ in their expectations for and experiences of communications about the parent's death but they also differ in their levels of felt closeness in the family, a situation which might markedly affect the child's subsequent emotional development.

After ASSIST, what next? SCIENCE

Cardiovascular consequences of cocaine use are well known, and surveillance for them is common practice in the routine care of cocaine abusers. However, the cardiac electrical abnormalities that arise, although studied in animal experiments, lack correlation with human reports. The case of a 17-year-old girl, who was admitted after a cocaine binge is reported. She was cardiologically asymptomatic, but an admission electrocardiogram was abnormal, with QT interval prolongation. This returned to normal within 24 hours of observation. The literature on the electrophysiologic effects of cocaine on the heart is reviewed.     

After the storm: Recognition, recovery, and reconstruction.

On August 29, 2005, when Hurricane Katrina made landfall near the Louisiana-Mississippi border, it exposed a large number of people to extraordinary loss and suffering. The enormous swath of physical devastation wreaked across the marshes of Louisiana's Plaquemines Parish to the urban communities of New Orleans and the coastal landscape of Mississippi and Alabama caused a notable change to the demographics of the Gulf Region, making it the most expensive natural disaster in U.S. history. This article describes a disaster responder's experiences of working with displaced survivors of Hurricane Katrina, providing crisis and mental health support in the acute phase of the disaster. This is followed by a discussion of the importance of a multicultural approach to helping survivors of a natural disaster; several guidelines to improve multicultural competence are proposed. In particular, the importance of attending to survivors' racial, socioeconomic, language, and religious differences is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Response of Slab Bridges Before, During, and After Repair

Continuous reinforced concrete slab bridges rely on reinforcing steel bars near the top of the deck over the piers to carry negative moment. Transfer of forces in these bars may be jeopardized by deterioration and repair procedures that involve variable depth removal of deteriorated concrete around the bars. Partial or full loss of continuity could overstress the bottom reinforcement. Truckload testing of three bridges with various levels of damage was conducted before, during, and after repair in an attempt to quantify the level of loss of continuity and to examine the effectiveness of repair in terms of increasing the load transfer and enhancing the overall stiffness. Test results show loss of stiffness during repair but increased stiffness after completion of repair. The continuity was found to be lost during repair, and the slab dead load positive moments may be increased by as much as 50%. After repair, the continuity was restored, and the live-load distribution was essentially unaltered. For the test bridges, the redistribution of dead-load moment to the positive-moment zones did not appreciably affect the overall bridge rating factor. The amount of moment redistribution may be controlled through planning of repair steps.     

After health sector reform, whither lung health?

Despite the importance of limited proteolysis in biological systems it is often difficult to rationalize why a proteinase hydrolyses a particular bond, given a simple sequence specificity alone. Understanding of the structural properties limiting the proteolysis represents a first step on the pathway to control and manipulation of this phenomena. An expanded set of nick-sites in proteins of known tertiary structure, cut by both narrow and broad specificity proteinases, has been generated yielding a robust data set of strictly limited sites. A critical evaluation of an expanded set of conformational parameters revealed a strong correlation with limited proteolytic sites, although they are only modest predictors in isolation. The overall predictive power is significantly improved when the conformational parameters are combined in a weighted predictive scheme that permits their relative importance to be compared via a Metropolis search protocol. A subset of the parameters performs equally well demonstrating the key determinants of susceptibility. The derived predictive algorithm has been made available via the internet. Its utility for predicting other surface-correlated features is also discussed.     

c-Fos After Incentive Shifts: Expectancy, Incredulity, and Recovery.

Rats were used in a successive negative contrast procedure to determine which brain structures were activated by sucrose concentration downshifts, and on what day this occurred. Subjects were given preshift solutions for 12 days before being shifted to their postshift concentrations. Groups included 2 unshifted controls (32%-32% and 4%-4%) and 1 shifted group (32%-4%). Half of each group was killed 1 hr after the first exposure to the shifted solution (Shift 1), and half after the second exposure (Shift 2). Brains were processed for c-Fos-like immunoreactivity (FLI). Two major patterns emerged. Terminal drinking of 32% sucrose activated minimal brainstem regions involved in palatable taste, visceral feedback, and fluid homeostasis. In contrast, shifted subjects showed extensive cortical activation with selective activation in cerebral nuclei and brainstem. Robust FLI on Shift 1 was absent on Shift 2, consistent with evidence for rapid (1-trial) changes in all major motor outputs mediated by expectancy.

Microstructure of a Variety of Cokes After Alkali Enrichment

 It is difficult to distinguish tamping coke and top charging coke by conventional testing methods, such as cold strength, abrasion resistance, reactivity and strength after reaction. Some of tamping coke′s properties were even better than those of top charging coke, but from practical using effects of blast furnace, tamping coke was not as good as top charging coke. The reaction conditions were featured as high temperature, high alkali condition, intense reaction atmosphere and short time. Distribution of porosity in profile, microstructure and slag forming property of ash were analyzed and following conclusions were obtained. After alkali-rich reaction, there were obvious differences between top charging coke and tamping coke in microstructure. The porosity′s unevenness of tamping coke was greater than those of top charging coke, and tamping coke was with less and big pores in out space and inner part was dense with more throughout pores. After phase diagram and microstructure analysis, it could be obtained that ash forming characteristics of top charging coke were better than those of tamping coke, and top charging coke′s pores were blocked more seriously than those of tamping coke. From analysis of tuyere samples, it could be found that calcium content of ash in coke′s pores was small and it should belong to coke′s inherent ash; kalium (wK=28%) was unusually high in coke, so the situation of high alkali was close to real blast furnace reaction condition.
