Cervical Internal OS Cerclage: Description of a New Technique and Comparison with Shirodkar Operation

Internal os cerclage for cervical incompetence was performed in 90 patients who had previous McDonald procedure failure (70 patients) or had unfavorable cervical anatomy (short or lacerated cervix) for primary McDonald type cerclage (20 patients). Two different techniques were used: the Shirodkar operation (n = 44) with Mersilene band, and a simpler new technique (n = 46). The new technique is characterized by anterior colpotomy for exposure of the internal os, and a 0.6 mm nylon suture encircling the cervix to be tied high in the posterior fornix. The pregnancy outcome for both groups was similar. Late abortions of 8.7 and 11% and premature deliveries of 13 and 18% occurred in the new technique and the Shirodkar groups, respectively. The removal of the suture was generally difficult in the Shirodkar group and in eight patients analgesia and sedation were required. In the new technique group, the removal was easier and in only one patient was sedation required (p less than 0.0001). Severe vaginal discharge was found in 52% of the Shirodkar patients and none in the other group. Apparently the monofilament nylon suture prevented this side effect. It seems that the new technique is simpler to perform, involves fewer side effects, the removal of the suture is easier, and it is as effective as the Shirodkar procedure.
On the Peculiarities of Loyalty: A Diary Study of Responses to Dissatisfaction in Everyday Life

Research on exit, voice, loyalty, and neglect suggests an enigma: Whereas responding to dissatisfying incidents with exit or neglect is generally harmful-and whereas voice is generally beneficial loyalty does not reliably yield favorable consequences. A diary study of dating partners' responses to dissatisfying incidents revealed results consistent with two explanations of the unreliable payoffs of loyalty. First, loyalty is less "visible" than the other responses: Partners exhibited less agreement about the occurrence of loyalty than other responses; individuals reported greater frequencies of loyalty for themselves than for their partners; and there were greater discrepancies between perceived frequencies of voice relative to loyalty for partner than for self: Thus, when an individual behaves loyally, this response frequently remains unnoticed (or is misinterpreted). Second, because acts of loyalty operate in an indirect manner; they frequently produce less extreme outcomes: Although loyalty responses were judged to yield more constructive consequences than exit and neglect, loyalty was judged less constructive than voice.
Progestin stimulates the biosynthesis of fibronectin and accumulation of fibronectin mRNA in human endometrial stromal cells.

Fibronectin is a major component of decidual basement membrane. In the present study, we have investigated the effect of progestin on the synthesis and secretion of fibronectin in human endometrial stromal cells. Stromal cells were isolated during the menstrual cycle and cultured in RPMI-1640 with 2% fetal calf serum supplemented with progesterone or medroxyprogesterone acetate (MPA) in a long-term culture system. Indirect immunofluorescent staining showed that fibronectin was uniformly distributed in the intracellular and extracellular regions of stromal cells treated with MPA for 14 days. The biosynthesis and secretion of this protein and the accumulation of cellular fibronectin mRNA were studied after various culture periods. Cells were pulse-labelled with [35S]methionine to determine the amount of newly synthesized fibronectin secreted into the culture medium. A monoclonal antibody (Mab) identified human fibronectin on SDS-polyacrylamide gel electrophoresis (SDS-PAGE), showing a predominant band (Mr 230-250 kDa) which migrated with authentic fibronectin run in parallel. In six endometrial specimens, the amount of radioactivity incorporated as [35S]fibronectin was increased by progestin. Maximal stimulation occurred after 6 days treatment with MPA. Culture beyond 16 days reduced the rate of synthesis and secretion to 40% of the maximum. The effect of progestin was dose dependent with 0.02, 0.2 and 1 microM progesterone, producing 2.0, 3.8 and 11-fold increases respectively, over the control. Medroxyprogesterone acetate was more effective than progesterone, the maximal response (10-fold increase) being achieved at 0.02 microM MPA. (ABSTRACT TRUNCATED AT 250 WORDS)
Effects of instructional and motivational self-talk on balance performance in knee injured

Abstract Aims: To examine the influence of motivational and instructional self-talk on balance test performance of knee injured active individuals with meniscectomy. Design: One between-groups factor with four levels (instructional, motivational, no self-talk, neutral self-talk) and one within-groups “time” factor with two levels (pre-test, post-test). Method: 35 men and 25 women physically active and knee injured following meniscectomy 6 months ago participated. After 2 days of familiarization, they completed four dynamic balance stability trials, spaced 3 min apart. After the first two trials (best value as pre-test score), the participants were randomly assigned to four groups: the motivational self-talk group, instructional self-talk group and control groups (no instruction and neutral self-talk). They repeated the two trials (best value as post-test score) expressing aloud the phrases assigned. Results: Analysis of variance repeated-measures and Sidak multiple comparisons tests were performed on the time variable to detect differences in each group for each time point (pre- and post-test). Statistical analysis showed that balance board time score increased significantly only for experimental groups after the intervention period and not for control groups, F(3,56) = 9.93, p < 0.05, η2 = 0.861 for time of keeping stability on the board. Conclusions: The findings of the present study indicate that injured active individuals with meniscectomy may enhance their balance test performance via the use of instructional and motivational self-talk.
Completing Life Histories with Imputed Exit Dates: A Method for Historical Data from Passive Registration Systems

Life histories can often be reconstructed from administrative sources and other documents that report specific events, like birth, death, visiting a physician, applying for insurance, or using a service. In a "passive registration" system, individuals are not under continuous surveillance, and subjects are only known to be present when an event occurs. When individuals move out of the registration area without reporting their movements, the censoring times for those life histories are unobserved. This paper describes a new technique for imputing missing exit dates. Our approach uses information from other events (e.g. births, marriages, deaths) affecting the subject and closely related individuals to estimate the distribution of times between last observed events and (unobserved) exits from the registration area. We take into account differences related to age, sex, marital status, and past migration history. The method is tested on data from nineteenth-century Belgium in which exit dates are explicitly reported.
Measuring distinct types of musical self-efficacy

This research examines the specific nature of self-efficacy beliefs within music. Separate questionnaires assessing self-efficacy for musical learning and self-efficacy for musical performing were developed and tested, and the reliability of the new questionnaires was demonstrated using internal reliability tests and exploratory factor analysis. A sample of 250 conservatoire and university music students completed the two questionnaires and provided self-ratings of musical skills and attributes. The learning and performing questionnaires produced robust Cronbach alphas of . 82 and . 78, respectively. Exploratory factor analysis confirmed a single underlying factor within each questionnaire, and the stability of these questionnaires over time was established through the absence of significant differences in test—retest scores over a period of two to four weeks. Conservatoire students’ self-efficacy for musical learning was higher than that of university students, whereas there were no significant differences between conservatoire and university students in self-efficacy for musical performing. The two questionnaires also showed different patterns of correlations with a range of self-assessed musical skills and attributes, further demonstrating their distinctiveness. These results, which underline the need for differentiation in musical self-efficacy, highlight the importance of specificity and correspondence when measuring self-efficacy beliefs. The implications for measuring self-efficacy within other domains are discussed.
Butches, Bullies and Buffoons: Images of Physical Education Teachers in the Movies

The purpose of this study was to examine the cinematic images of physical educators during the past decade. This study is approached from two perspectives: (a) framing and (b) social cognition. Framing, an approach to media studies most often reserved for critical analysis of news, provides useful generalities for a formative study of movie images, which directs explicit attention toward the construction and use of media frames. Contemporary social cognition theory blends social learning theory with an understanding of the power of media images. Media observers (i.e. movie viewers) can acquire symbolic representations of behavior through media images and these images are powerful and informative enough to inform subsequent behavior. Using the Internet Movie Database (IMDB), each researcher compiled a list of movies. After an initial list from the IMDB was compiled, researchers added films that they knew, from personal knowledge, included physical education teachers. A final list of 18 movies was distributed to each of the four coders, with a stipulation that the coding take place during a specified time period of no more than three months. Each researcher observed the videotapes independently while noting the dialogue and camera shots of all scenes involving physical educators for emerging frames of reference regarding physical education teachers. Ethnographic content analysis, a media studies variation of the constant comparative method, aided in the identification of frames (categories and themes) that emerged from the data. The researchers independently made notes concerning the video observations and then later developed a system of classification by comparing notes and discovering regularities within the data. The constant comparative method was used to assist in the assessment and grouping of framing approaches. Agreement between researchers had to be 100% for a frame to be included in research findings. It was agreed that frames had to be constructed by both verbal and visual indicators in the films, and it had to be strongly associated with at least three films. Although nuances in setting, plot and the personalities of characters might arguably make frames in each film studied 'unique', several frames emerged as characteristic of depictions of physical educators: (a) there is no distinction between physical educators and coaches, (b) physical educators are incompetent teachers, (c) physical educators are drill sergeants and are the proverbial 'bully from hell' who enjoys seeing a student humiliated, and (d) characteristics of physical educators are gendered: women are often depicted as 'butch' or lesbian; men, as buffoons devoid of 'masculine' leadership qualities. An understanding of these frames is important because it provides clues about social cognition and behavior in regard to issues of physical education--from the classroom to the school board meeting, from decisions made about participation in physical education class to decisions made about the priority of physical education in the school setting.
Grafting, going to college and working on road: youth transitions and cultures in an East London neighbourhood

The local neighbourhood has an enduring significance for British urban, working-class youth in relation to their transitions, cultures and leisure practices. This paper examines these interrelated issues by drawing upon ethnographic research undertaken in ‘Manor’, a deprived, multi-ethnic East London neighbourhood. It explores the transitions taken by black, white and mixed-parentage young males (and some of their female peers), transitions that were formed by the interaction of paid work opportunities with youth cultures and leisure practices (‘road’ and ‘grafter’ cultures), ethnicity, gender and social networks. Even within a single deprived and stigmatized neighbourhood such as Manor, a number of transitions could be identified. These include ‘grafting’ at manual, masculine ‘dirty work’ in the construction industry; going to college allied to ‘clean’, service-sector work; and an ‘alternative’ route of ‘working on road’ by undertaking a variety of low-level, illegal money-making activities.
Perceptions of Febrile Illness among Local People Living in Malaria Endemic villages in Central Hill Region of Nepal

Objective of this paper is to explore the perceptions of febrile illness among people living in malaria endemic areas of hill region. Qualitative data were collected from malaria endemic villages in Mahadevesthan VDC of Kavrepalanchok district through in-depth interviews and focus group discussions. Local people perceive febrile illnesses as common health problem. They classified febrile illnesses into sardi ko jwaro, dokh, lagu/laganiko jwaro and aulo jwaro. Fever occurring after engaging in heavy physical work is described as dagdi. Severe and complicated form of fever is interpreted as dokh in cultural meaning and typhoid as biomedical concept. Febrile illness which does not respond to biomedicine, but it is relieved by traditional ritual healing is labeled as lagani ko jwaro. Malaria fever is locally known as aul or aulo jwaro. People often avoid certain food such as sour curd, meat, egg, oily and spicy food during fever to prevent it from resulting in dokh (complicated fever). Herbal home remedy is rarely used in febrile illness. Now a day, local people interpret dokh as typhoid and aulo as malaria fever and seek medical treatment from local health institutions and private practitioners. Local perceptions of febrile illnesses such as dokh and aulo overlap with the biomedical concepts of typhoid and malaria fever due to interaction with both traditional healers and health care providers.

Bacterial Leaching of Metal Sulfides Proceeds by Two Indirect Mechanisms via Thiosulfate or via Polysulfides and Sulfur

ABSTRACT The acid-insoluble metal sulfides FeS2, MoS2, and WS2 are chemically attacked by iron(III) hexahydrate ions, generating thiosulfate, which is oxidized to sulfuric acid. Other metal sulfides are attacked by iron(III) ions and by protons, resulting in the formation of elemental sulfur via intermediary polysulfides. Sulfur is biooxidized to sulfuric acid. This explains leaching of metal sulfides by Thiobacillus thiooxidans.
Seeing Things Unseen: Fantasy Beliefs and False Reports

Whereas past research has demonstrated that children's beliefs about the real world can influence their memory for events, the role of fantasy beliefs in children's recall remains largely unexplored. We examine this topic in 5- and 6-year-olds by focusing on how belief in a familiar fantasy figure, namely the Tooth Fairy, is related to children's memory for their most recent primary tooth loss. Although children who fully believed in the reality of the Tooth Fairy provided more voluminous and complex accounts than those with less strong beliefs, they also provided the most fictitious reports, frequently characterized by claims of hearing or seeing the Tooth Fairy. Belief in the Tooth Fairy did not affect the accuracy of children's reports of the mundane elements of their tooth loss, and many fantastic claims were linked to real events. Exposure to seemingly tangible evidence of the Tooth Fairy's existence was associated with the provision of fantastic claims. This research was supported by a grant from Ursinus College. Portions of this research were presented at the meetings of the Cognitive Development Society, San Diego, CA, October 2005, and the Society for Research in Child Development, Boston, MA, April 2007.
Field testing of a self-instructional time management manual with managerial staff in an institutional setting.

Despite the extensive literature advocating the virtues of time management, research demonstrating its effectiveness is almost nonexistent. In this study, a step-by-step self-instructional time management manual was prepared and field tested with managerial staff of a large residential institution for retarded individuals. Experiment 1 used a multiple baseline design across groups to assess the effectiveness of the manual with instructor contact. Questionnaire and corroboration data clearly showed an increase in time management practices of participants as a function of training. These improvements were largely maintained at a four-week follow-up. Social validation measures revealed that participants found the manual to be easily readable and relevant to work and/or personal situations. In addition, improvements in participants' time management behaviors were readily discriminable by colleagues. Experiment 2 assessed the effectiveness of the manual versus a best-selling time management paperback book, und.
Beyond Contact: Intergroup Contact in the Context of Power Relations

This work investigated how group-based power affects the motivations and preferences that members of advantaged and disadvantaged groups bring to situations of contact. To measure the preferred content of interactions, desires to address particular topics in intergroup contact were assessed for both experimental groups (Study 1) and real groups (Study 2). As predicted, across both studies, the desire to talk about power was greater among members of disadvantaged than of advantaged groups. This difference was mediated by motivation for change in group-based power. Study 2 further demonstrated that more highly identified members of disadvantaged groups wanted to talk about power more. Members of advantaged groups generally preferred to talk about commonalities between the groups more than about group-based power, and this desire was greater with higher levels of identification. However, perceiving that their group's advantage was illegitimate increased the desire of advantaged group members to address power in intergroup interactions.
The Zinc-Fingers of KREPA3 Are Essential for the Complete Editing of Mitochondrial mRNAs in Trypanosoma brucei

Most mitochondrial mRNAs in trypanosomes undergo uridine insertion/deletion editing that is catalyzed by ∼20S editosomes. The editosome component KREPA3 is essential for editosome structural integrity and its two zinc finger (ZF) motifs are essential for editing in vivo but not in vitro. KREPA3 function was further explored by examining the consequence of mutation of its N- and C- terminal ZFs (ZF1 and ZF2, respectively). Exclusively expressed myc-tagged KREPA3 with ZF2 mutation resulted in lower KREPA3 abundance and a relative increase in KREPA2 and KREL1 proteins. Detailed analysis of edited RNA products revealed the accumulation of partially edited mRNAs with less insertion editing compared to the partially edited mRNAs found in the cells with wild type KREPA3 expression. Mutation of ZF1 in TAP-tagged KREPA3 also resulted in accumulation of partially edited mRNAs that were shorter and only edited in the 3′-terminal editing region. Mutation of both ZFs essentially eliminated partially edited mRNA. The mutations did not affect gRNA abundance. These data indicate that both ZFs are essential for the progression of editing and perhaps its accuracy, which suggests that KREPA3 plays roles in the editing process via its ZFs interaction with editosome proteins and/or RNA substrates.
Cathepsin L Inhibition Prevents Murine Autoimmune Diabetes via Suppression of CD8+ T Cell Activity

Background Type 1 diabetes (T1D) is an autoimmune disease resulting from defects in central and peripheral tolerance and characterized by T cell-mediated destruction of islet β cells. To determine whether specific lysosomal proteases might influence the outcome of a T cell–mediated autoimmune response, we examined the functional significance of cathepsin inhibition on autoimmune T1D-prone non-obese diabetic (NOD) mice. Methods and Findings Here it was found that specific inhibition of cathepsin L affords strong protection from cyclophosphamide (CY)-induced insulitis and diabetes of NOD mice at the advanced stage of CD8+ T cell infiltration via inhibiting granzyme activity. It was discovered that cathepsin L inhibition prevents cytotoxic activity of CD8+ T cells in the pancreatic islets through controlling dipeptidyl peptidase I activity. Moreover, the gene targeting for cathepsin L with application of in vivo siRNA administration successfully prevented CY-induced diabetes of NOD mice. Finally, cathepsin L mRNA expression of peripheral CD8+ T cells from NOD mice developing spontaneous T1D was significantly increased compared with that from control mice. Conclusions Our results identified a novel function of cathepsin L as an enzyme whose activity is essential for the progression of CD8+ T cell-mediated autoimmune diabetes, and inhibition of cathepsin L as a powerful therapeutic strategy for autoimmune diabetes.
A Pilot Study of a Kindergarten Summer School Reading Program in High-Poverty Urban Schools

This pilot study examined an implementation of a kindergarten summer school reading program in 4 high-poverty urban schools. The program targeted both basic reading skills and oral language development. Students were randomly assigned to a treatment group (n = 25) or a typical practice comparison group (n = 28) within each school; however, randomization was compromised due to school circumstances, resulting in a quasi-experimental design. Instruction was delivered by the schools' regular teachers during 20 full-day summer school sessions. Each day treatment group students received large-group listening comprehension and vocabulary lessons anchored in storybook reading, along with small-group lessons focused on basic reading skills and listening comprehension. The intervention was associated with improved outcomes for treatment group students in word reading and listening comprehension with mixed results for phonemic awareness and no significant between-group differences in reading fluency or vocabulary. Such an approach is potentially efficacious, suggesting the need for further research.
Detecting Moving Shadows: Algorithms and Evaluation

Moving shadows need careful consideration in the development of robust dynamic scene analysis systems. Moving shadow detection is critical for accurate object detection in video streams since shadow points are often misclassified as object points, causing errors in segmentation and tracking. Many algorithms have been proposed in the literature that deal with shadows. However, a comparative evaluation of the existing approaches is still lacking. In this paper, we present a comprehensive survey of moving shadow detection approaches. We organize contributions reported in the literature in four classes two of them are statistical and two are deterministic. We also present a comparative empirical evaluation of representative algorithms selected from these four classes. Novel quantitative (detection and discrimination rate) and qualitative metrics (scene and object independence, flexibility to shadow situations, and robustness to noise) are proposed to evaluate these classes of algorithms on a benchmark suite of indoor and outdoor video sequences. These video sequences and associated "ground-truth" data are made available at http://cvrr.ucsd. edu/aton/shadow to allow for others in the community to experiment with new algorithms and metrics.
