"I want to read stuff on boys": white, Latina, and black girls reading seventeen magazine and encountering adolescence.

This study is based on interviews with four focus groups consisting of fourteen white, Latina, and black girls, ages 13 to 16 years, from diverse backgrounds. The objectives of the study are to gain insight into what forum girls use to learn about the adolescent experience and to examine teenage girls' views of their sexuality and femininity. The girls' discussion of their lives and perceptions of the teen magazine Seventeen reveal a displacement of female sexuality. The magazine's message to teenage girls of gaining self-worth through emphasized femininity seems to resonate with these girls regardless of class and race. We conclude that responsible adults need to challenge the distorted media images of adolescent development and teenage girls' sexuality.
Cholesterol efflux potential of sera from mice expressing human cholesteryl ester transfer protein and/or human apolipoprotein AI.

The ability of whole serum to promote cell cholesterol efflux and the relationships between apoprotein and lipoprotein components of human serum efflux have been investigated previously (de la Llera Moya, M., V. Atger, J.L. Paul, N. Fournier, N. Moatti, P. Giral, K.E. Friday, and G.H. Rothblat. 1994. Arterioscler. Thromb. 14:1056-1065). We have now used this experimental system to study the selective effects of two human lipoprotein-related proteins, apoprotein AI (apo AI) and cholesteryl ester transfer protein (CETP) on cell cholesterol efflux, when these proteins are expressed in transgenic mice. The percent efflux values for cholesterol released in 4 h from Fu5AH donor cells to 5% sera from the different groups of mice were in the order: background = human apo AI transgenic (HuAITg) > human CETP transgenic (HuCETPTg) > human apo AI and CETP transgenic (HuAICETPTg) >> apo AI knockout mice. In each group of mice a strong, positive correlation (r2 ranging from 0.64 to 0.76) was found between efflux and HDL cholesterol concentrations. The slopes of these regression lines differed between groups of mice, indicating that the cholesterol acceptor efficiencies of the sera differed among groups. These differences in relative efficiencies can explain why cholesterol efflux was not proportional to the different HDL levels in the various groups of mice. We can conclude that: (a) HDL particles from HuAITg mice are less efficient as cholesterol acceptors than HDL from the background mice; (b) despite a lower average efflux due to lower HDL cholesterol concentrations, HDL particles are more efficient in the HuCETPTg mice than in the background mice; and (c) the coexpression of both human apo AI and CETP improves the efficiency of HDL particles in the HuAICETPTg mice when compared with the HuAITg mice. We also demonstrated that the esterification of the free cholesterol released from the cells by lecithin cholesterol acyltransferase in the serum was reduced in the HuAITg and AI knockout mice, whereas it was not different from background values in the two groups of mice expressing human CETP.
New Algorithms for GPU Stream Compaction - A Comparative Study

With the advent of GPU programmability, many applications have transferred computational intensive tasks into it. Some of them compute intermediate data comprised by a mixture of relevant and irrelevant elements in respect to further processing tasks. Hence, the ability to discard irrelevant data and preserve the relevant portion is a desired feature, with benefits on further computational effort, memory and communication bandwidth. Parallel stream compaction is an operation that, given a discriminator, is able to output the valid elements discarding the rest. In this paper we contribute two original algorithms for parallel stream compaction on the GPU. We tested and compared our proposals with state-of-art algorithms against different data-sets. Results demonstrate that our proposals can outperform prior algorithms. Result analysis also demonstrate that there is not a best algorithm for all data distributions and that such optimal setting is difficult to be achieved without prior knowledge of the data characteristics.
CII Repair Pattern in the Reticular Lamina of the Organ of Corti after Hair Cell Loss

The cytoarchitecture of the organ of Corti has a very regular pattern. The regularity in the mosaic arrangement of the reticular lamina of the organ of Corti is particularly impressive. The organ of Corti, a highly differentiated organ, is known to be so sensitive and fragile that after long-term or high dose administration of amino-glycosidic antibiotics or after intense sound exposure it is easily damaged. In recent years, Kohonen,' Engstrom et al.,2,3 Bredberg,' and [ohnsson and Hawkins" have made use of phase contrast microscopy after osmic acid fixation of the cochlear tissues for studying large areas of the cochlea by surface preparations.Y In 1965, Kohoneu' studied the effect of some ototoxic antibiotics upon the pattern of sensory cell loss using the same method.
Consumer satisfaction and child behaviour problems in child and adolescent mental health services

Consumer satisfaction with health care is one of the goals of health care delivery. Information on what affects satisfaction helps health care providers to deliver patient-centred care. The aim of this study was to explore the relationship between young persons' symptoms and satisfaction with Child and Adolescent Mental Health Services (CAMHS). It also examined differences in satisfaction of the parent/carer and their child. Self-report questionnaires were used to gather information from respondents. High levels of satisfaction were reported, although children and adolescents were less satisfied than parents/carers. Young people with self-reported conduct problems were least satisfied with CAMHS, as were those who rated their problems as having a significant impact on their lives. There was no relationship between carer-reported ‘caseness’ and carer satisfaction with services. Further exploration of the needs and expectations of young people who have behavioural difficulties is necessary so that their needs are better understood and expectations met.
Multiple Primary Malignant Neoplasms in Pancreatic Cancer Patients: A Single-Center Experience in Korea

To the Editor: A second primary malignant neoplasm is a new tumor that is biologically independent of a preceding neoplasm.1 Second primary cancers constitute approximately 4% to 10% of the malignancies diagnosed. Multiple primary malignant neoplasms seem to have increased in frequency over the years. This may be attributed to improved clinical awareness, possible effects of new environmental carcinogenic forces, increased use of chemotherapeutic agents that are carcinogens, and, to some extent, increased longevity of cancer patients, which enables them to live long enough to develop a second primary cancer. A study on second primary malignant neoplasms may thus provide data on the etiologic factors of the second and the first neoplasms, particularly for those with limited etiologic information, such as pancreatic cancer. However, limited studies on multiple primary malignancies in patients with sporadic exocrine pancreatic cancers are documented. The aim of this study was to determine the characteristics of multiple primary malignancies in patients with sporadic exocrine pancreatic cancers.
Testosterone Therapy in Obliterating Arterial Lesions in the Lower Limbs

The basis was established for a rational sex hormone therapy with the isolation of the estrogenicl 2 sand androgenic hormones.3 It has been demonstrated by animal experiments that a basic effect of the sex hormones is hyperemization of the whole organism.4 4 When this observation was confirmed with regards to the skin in the 1930’s in patients treated for well defined gonad insufficiency, the possibility then existed of treating patients with diseases of the circulatory system with sex hormones.
Using an augmentable resource to robustly and purposefully navigate a robot

Presents a scheme for specifying and executing purposive navigation tasks for a behaviour-based mobile robot. A user specifies the robot's navigation task in general and qualitative terms using a graphical resource called the purposive map (PM). The robot navigates using the incomplete and approximate information stored in the PM as an aid to achieve the specified mission. The robot is able to augment the knowledge provided in the PM with environment information learnt by the robot. Using the augmented PM, the robot learns how to perform efficient obstacle avoidance. The authors present experimental results using a real robot to show their scheme is robust. The authors' robot can escape from dead-ends, can deduce that goals are unreachable and can withstand disturbances to the environment between missions.
Prevalence of metabolic syndrome in adult hypopituitary growth hormone (GH)-deficient patients before and after GH replacement.

CONTEXT AND OBJECTIVE Metabolic and body compositional consequences of GH deficiency (GHD) in adults are associated with a phenotype similar to the metabolic syndrome (MetS). PATIENTS We assessed MetS prevalence in adult GHD patients (n = 2531) enrolled in the Hypopituitary Control and Complications Study. Prevalence was assessed at baseline and after 3 yr of GH replacement in a subset of 346 adult-onset patients. RESULTS Baseline MetS crude prevalence was 42.3%; age-adjusted prevalence in the United States and Europe was 51.8 and 28.6% (P < 0.001), respectively. In the United States, age-adjusted prevalence was significantly higher (P < 0.001) than in a general population survey. Increased MetS risk at baseline was observed for age 40 yr or older (adjusted relative risk 1.34, 95% confidence interval 1.17-1.53, P < 0.001), females (1.15, 1.05-1.25, P = 0.002), and adult onset (1.77, 1.44-2.18, P < 0.001). In GH-treated adult-onset patients, MetS prevalence was not changed after 3 yr (42.5-45.7%, P = 0.172), but significant changes were seen for waist circumference (62.1-56.9%, P = 0.008), fasting glucose (26.0-32.4%, P < 0.001), and blood pressure (59.8-69.7%, P < 0.001). Significantly increased risk of MetS at yr 3 was associated with baseline MetS (adjusted relative risk 4.09, 95% confidence interval 3.02-5.53, P < 0.001) and body mass index 30 kg/m(2) or greater (1.53, 1.17-1.99, P = 0.002) and increased risk (with a P value < 0.1) for GH dose 600 microg/d or greater (1.18, 95% confidence interval 0.98-1.44, P = 0.088). CONCLUSION MetS prevalence in GHD patients was higher than in the general population in the United States and higher in the United States than Europe. Prevalence was unaffected by GH replacement, but baseline MetS status and obesity were strong predictors of MetS after GH treatment.
Uniqueness and approximate computation of optimal incomplete transportation plans

For a given trimming level 2 (0,1) an trimmed version, P , of a probability P is a new probability obtained by re-weighting the probability of any Borel set, B, according a positive weight function, f 1 1 , in the way P (B) = R B f(x)P(dx). If P,Q are probability measures on an euclidean space, we consider the optimization problem of obtaining the best L2 Wasserstein approximation between say a fixed probability and trimmed versions of the other, say trimmed versions of both probabilities. These best trimmed approximations naturally lead to new perspectives in the theory of Mass Transportation, where a part of the mass could be not necessarily transported. Since optimal transportation plans are not easily computable, we provide theoretical support for Monte-Carlo approximations, through a general consistency result. As a remarkable and unexpected additional result, with important implications for future work, we obtain the uniqueness of the optimal solution. Notice that such solution involves an optimal map T transporting some trimmed version P of P to some other Q of Q, thus for any point x in the support of P the weight function associated to P allows to partially or completely avoid the consideration of x in the transport. Our results show that in fact only the non-trimmed points (verifying f(x) = 1 1 ) are transported, while the partially trimmed points (verifying 0 < f(x) < 1 1 ) must remain untransported by T.
Overtreatment with removable partial dentures in shortened dental arches.

In our cultural pattern shortened dental arches are frequently seen, as molars are often seriously afflicted by caries and periodontal disease. The necessary restorative treatment is often omitted because of lack of motivation and/or financial limitations. Clinical investigations among subjects with shortened dental arches show that there is sufficient adaptive capacity to maintain adequate oral function when at least tour occlusal units are left, preferably in a symmetrical position. Treatment by providing free-end removable partial dentures introduces unfavourable conditions for the remaining dentition. Overtreatment with these appliances is caused by traditional mechanically and morphologically oriented occlusal concepts, disregard of the adaptive capacity in biologic systems, and quantity promoting fee schedules. Problem solving approaches in occlusal therapy should be stimulated to prevent overtreatment.
Mobile IP Traversal of Network Address Translation (NAT) Devices

Mobile IP's datagram tunnelling is incompatible with Network Address Translation (NAT). This document presents extensions to the Mobile IP protocol and a tunnelling method which permits mobile nodes using Mobile IP to operate in private address networks which are separated from the public internet by NAT devices. The NAT traversal is based on using the Mobile IP Home Agent UDP port for encapsulated data traffic.
Melatonin and exposure to constant light/darkness affects ovarian follicular kinetics and estrous cycle in Indian desert gerbil Meriones hurrianae.

Melatonin mediates photoperiodic influence on reproduction and constant light and darkness affect pineal biosynthesis of melatonin. The present study was undertaken to assess the effects of melatonin and drastic photoperiodic changes on reproduction in a tropical desert species with a fossorial lifestyle. Ovarian follicular kinetics and estrous cycle were studied in the Indian desert gerbil Meriones hurrianae, after treatment with melatonin and exposure to constant light (LL) and darkness (DD) regimes. Melatonin treatment increased (P < 0.001) ovarian weights without changing the uterine weights. While exposure to LL decreased (P < 0.001) both ovarian and uterine weights, exposure to DD had no effect on these weights. Follicular kinetics of growing and regressing follicles revealed that ovaries of melatonin-treated and DD-exposed animals had significantly more growing follicles. Melatonin treatment increased all types of growing follicles, especially antral and Graafian follicles. Exposure to DD increased all types of growing follicles, with the medium sized antral and Graafian follicles being significant (P < 0.01). In contrast to stimulation of follicular growth by melatonin and DD, LL caused regression of all stages of follicular growth and also reduced the number of small preantral follicles. Melatonin treatment increased (P < 0.001) the length of estrous cycle (5.08 to 7.29 days). Gerbils treated with melatonin, exposed to LL and DD, had a longer (P < 0.001) metestrus. Animals held in LL, had the least number (P < 0.001) of estrous smears (1 in 30 days). The results suggest that melatonin is involved in growth of ovarian follicles in the Indian desert gerbil.
Race and Ethnic Differences and Human Figure Drawings: Clinical Utility of the DAP:SPED

This study examined race and ethnic differences on the Draw A Person: Screening Procedure for Emotional Disturbance (DAP:SPED; Naglieri, McNeish, & Bardos, 1991) for youths 6 though 17 years of age for 2 matched samples. Samples were drawn from the DAP:SPED nationally representative standardization sample and matched on gender, grade, and school classroom. No statistically significant differences were found for big figure, small figure, or shading item composites. A statistically significant difference was found between Black-White pairs on figure omissions but showed a small effect size (d value = .25). Further, no statistically significant differences were found between the DAP:SPED Total T scores for Black and White youth (M = 47.67, SD = 10.09; N =138) or Hispanic and White youth (M = 48.20, SD = 9.56; N = 59), showing very small effect sizes. In addition, equivalence testing showed similarities across race and ethnic pairs for all composites and DAP:SPED total score, lending preliminary support to the DAP:SPED's clinical utility as a measure that yields similar scores across these groups.
Inappropriate Prescribing and Health Outcomes in Elderly Veteran Outpatients

OBJECTIVE: To determine the relationship of inappropriate prescribing in the elderly to health outcomes. SETTING: General Medical Clinic of the Durham Veterans Affairs Medical Center. PATIENTS: A total of 208 veterans more than 65 years old who were each taking five or more drugs and participated in a pharmacist intervention trial. MEASUREMENTS: Prescribing appropriateness was assessed by a clinical pharmacist using the medication appropriateness index (MAI). A summed MAI score was calculated, with higher scores indicating less appropriate prescribing. The health outcomes were hospitalization, unscheduled ambulatory or emergency care visits, and blood pressure control. RESULTS: Bivariate analyses revealed that mean MAI scores at baseline were higher for those with hospital admissions (18.9 vs. 16.9, p = 0.07) and unscheduled ambulatory or emergency care visits (18.8 vs. 16.3, p = 0.05) over the subsequent 12 months than for those without admissions and emergency care visits. MAI scores for antihypertensive medications were higher for patients with inadequate blood pressure control (> 160/90 mm Hg) than for those whose blood pressure was controlled (4.7 vs. 3.1, p = 0.02). CONCLUSIONS: Inappropriate prescribing appeared to be associated with adverse health outcomes. This finding needs to be confirmed in future studies that have larger samples and control for potential confounders.
MR‐search: massively parallel heuristic search

MR‐Search is a framework for massively parallel heuristic search. Based on the MapReduce paradigm, it efficiently utilizes all available resources: processors, memories, and disks. MR‐Search uses OpenMP on shared memory systems, Message Passing Interface on clusters with distributed memory, and a combination of both on clusters with multi‐core processors. Large graphs that do not fit into the main memory can be efficiently processed with an out‐of‐core variant. We implemented two node expansion strategies in MR‐Search: breadth‐first frontier search and breadth‐first iterative deepening A*. With breadth‐first frontier search, we computed large and powerful table‐driven heuristics, so‐called pattern databases that exceed the main memory capacity. These pattern databases were then used to solve random instances of the 24‐puzzle with breadth‐first iterative deepening A* on systems with up to 4093 processor cores. MR‐Search is conceptually simple. It takes care of data partitioning, process scheduling, out‐of‐core data merging, communication, and synchronization. Application developers benefit from the parallel computational capacity without having the burden of implementing parallel application code. Copyright © 2011 John Wiley & Sons, Ltd.
Exposure to Schistosoma mansoni infection in a rural area in Brazil. Part III: household aggregation of water‐contact behaviour

Much research points to the importance of the household in the study of water‐borne diseases such as schistosomiasis. An important aspect of the household is the clustering of domestic activities associated with water collection, storage and usage. Such activities can result in the sharing of water‐contact sites and water‐contact behaviour, which expose household members to similar risks of infection. In previous studies, we determined that shared residence accounted for 28% of the variance in Schistosoma faecal egg excretion rates. We now quantify the effect of shared residence on the variation in water‐related health behaviours. We found that shared residence accounted for 30% of the variation in total water contacts per week. It also accounted for a large proportion of the variation in individual water‐contact behaviour: e.g. agricultural contacts (63%), washing limbs (56%) or bathing (41%). These results implicate the household as an important composite measure of the complex relationships between socioeconomic, environmental and behavioural factors that influence water‐contact behaviour and, therefore, the transmission of schistosomiasis. Our results also support a focus on the household in the implementation of schistosomiasis prevention and control efforts.
Parallel Programming with Polaris

Parallel programming tools are limited, making effective parallel programming difficult and cumbersome. Compilers that translate conventional sequential programs into parallel form would liberate programmers from the complexities of explicit, machine oriented parallel programming. The paper discusses parallel programming with Polaris, an experimental translator of conventional Fortran programs that target machines such as the Cray T3D.
Cascade induction of c-fos, c-myc, and heat shock 70K transcripts during regression of the rat ventral prostate gland.

Castration of an adult male rat results in the rapid regression of the ventral prostate gland. Most of the acinar epithelial cells lining the ducts of the gland will die during the first 5 days after androgen withdrawal. The molecular events which accompany the death of these cells were studied by examining RNA isolated from ventral prostate glands of normal and from a sequential 24-h series of castrate rats. These RNAs were analyzed by Northern blot methods to quantify the expression of growth-related (c-fos, c-myc, and heat shock 70K) and cell maintenance (alpha-tubulin) genes during prostatic regression. Each of these genes showed a bimodal pattern of expression. Within the first few days after castration, transcript levels decline; whereas later, during the most active period of cell death, their expression was transiently induced. Levels of mature c-myc, and alpha-tubulin transcripts increased approximately 6- to 8-fold on the third day after castration, while transcripts encoding hsp 70-related genes increased greater than 6-fold on the fourth day after castration. Further analysis of RNA extracted from regressing ventral prostate glands at sequential 12-h intervals after castration showed that the c-fos gene was induced at 36 h, earlier than c-myc, alpha-tubulin, and hsp 70.
