An alternative approach to evaluate the average Nusselt number for mixed boundary layer conditions in parallel flow over an isothermal flat plate
Authors: Stetsyuk Viacheslav , Kubiak Krzysztof J , Liu Lande , Chai John C
Published: December 2017

In this paper, we present an alternative approach to evaluate the average Nusselt number for mixed boundary layer conditions in parallel flow over an isothermal flat plate. This approach can be used regardless of the critical Reynolds number where the flow transitions from laminar flow to turbulent flow. This approach is simple and uses graphical visualisation of the physical situation. This should assist comprehension and retention. It utilises the average quantity for the laminar boundary layer and the average value for turbulent boundary layer to obtain the average quantities for mixed boundary layers without the need to perform the usual integration. It can easily be incorporated into part of undergraduate chemical, mechanical and petroleum engineering curricula. A worked example is included to show the utility of the approach.
Mental Health of Refugees and Asylum Seekers: Assessment and Intervention
Authors: Kronick Rachel
Published: December 2017

With unprecedented numbers of displaced persons worldwide, mental health clinicians in high-income countries will increasingly encounter refugee and asylum-seeking patients, many of whom have experienced significant adversity before and after their migration. This paper presents a summary of the recent evidence on the assessment and treatment of refugees across the lifespan to inform clinicians’ approaches to care of refugee patients in mental health care settings. Assessment and interventions for refugees are grounded in an ecosystemic approach which considers not only pre-migratory trauma, but social, familial, and cultural determinants of mental health in the host country. Evidence for psychotherapy and pharmacological treatments are reviewed, highlighting promising interventions while acknowledging that further research is needed. Ultimately, serving refugees necessitates a biopsychosocial approach that engages clinicians as medical experts, therapists, and advocates.

Transarterial embolization is an established minimally invasive treatment for solid tumors. Unintended inflammation, foreign body reactions and ischemia-triggered neoangiogenesis are clinical drawbacks of permanent embolic materials. The aim of the current study was to characterize a new type of biodegradable starch microsphere with regard to angiographic and histopathological features such as patterns of acute arterial occlusion as well as induction of tissue necrosis, microsphere biodegradation, and inflammation and foreign body reactions during follow-up. Key characteristics of both biodegradable prototypes (L1 and L2; prototype groups) were as follows: microspheres are biodegradable by serum α-amylase, produced from chemically crosslinked potato starch to different extents, in a diameter range of ∼300–800 µm, differing in size distribution and featuring a microsphere deformation of ∼1%. In vivo transarterial embolization with L1 and L2, while applying clinical standard techniques, was performed and compared with clinically established permanent microspheres (Embosphere®500-700 and Embosphere®700-900; control groups). Twenty-four pig kidneys were embolized with the different embolic materials by following the study protocol, and there were no technical failures or complications. Parenchymal necrosis with interstitial calcification was observed in all kidneys independent of the type of embolic material used. Compared with the permanent embolic materials, biodegradable microspheres showed complete (L1) or partial (L2) biodegradation within one week after transarterial embolization, and induced a comparable (L1) or a lower (L2) degree of arterial wall necrosis and a lower degree of inflammation and foreign body reactions. In conclusion, the presented new type of biodegradable microsphere is promising, and could be further evaluated in terms of clinical translation.
Career progression of female librarians in public university libraries in Ghana
Authors: Akpebu Adjah Olive , Van der Walt Thomas
Published: December 2017

The growing interest in gender issues and female employment has generated a number of studies and the library and information profession has not been excluded from this interest in promoting female equality in employment. This study investigates the career patterns of practising professional female librarians in six selected public university libraries in Ghana, in order to establish the enhancers and inhibitors they experience in their career progression. The study, conducted with a survey method, adopted the use of self-administered questionnaires for data collection. Quantitative data gathered from the 128 librarians were analysed to report on descriptive characteristics of respondents, while qualitative data, from open-ended questions, were analysed, using the narrative analysis technique, to present a profile of respondents and their career histories. The findings reveal females in the study were unable to meet requirements for promotion in their various public university libraries, which has resulted in very slow progress in their careers and even stagnated careers. The study concludes by recommending that there should be a career development support system for females, to help them overcome barriers to advancement in university libraries
Diversity in Cycas (Cycadales: Cycadaceae) Species Offered as Larval Food Influences Fecundity of Chilades pandava (Lepidoptera: Lycaenidae) Adults
Authors: Marler Thomas E , Lindström Anders J , Marler Paris N
Published: December 2017

Chilades pandava (Lepidoptera: Lycaenidae) larval food quality was studied to determine its influence on adult life history traits. A wild population from Cycas nongnoochiae (Cycadales: Cycadaceae) endemic habitat behaved similarly to the population collected from a garden setting. Cycas micronesica, Cycas revoluta, and Cycas seemannii leaves were used as high-quality food, whereas C nongnoochiae, Cycas taitungensis, and Cycas condaoensis leaves were used as low-quality food. The daily oviposition rate was not influenced by food quality, but longevity and lifetime fecundity of females were increased by high-quality larval food. These results indicate that in situ Cycas species impose a physiological constraint on the genetic capacity to produce offspring by C pandava. The removal of that constraint by high-quality novel Cycas species may be one reason this butterfly can increase in population rapidly after an invasion event and express greater herbivory of Cycas species within invaded regions.
The rise and fall of an opt-out system
Authors: Nordfalk Francisca , Hoeyer Klaus
Published: December 2017

Introduction: In Denmark, citizens participate in register-based research without the possibility of opting out. However, in 1995 it was made possible for Danish citizens to register an opt-out called ‘researcher protection’ [ forskerbeskyttelse], which implied that researchers could not contact people to invite them to participate in research projects, such as clinical trials or questionnaries, based on their registrations in national registers. Data already registered could still be used for research. In 2014, this possibility of opt-out was revoked by law. Aims: The aims of this paper are to understand how the Danish researcher protection system came about, why it was terminated and what we can we learn from this example. Methods: We conducted a descriptive analysis of a copy of the former researcher protection register along with policies and media debate surrounding the rise and revocation of the researcher protection system. Results: Our results show how both the inception and the abolishment of researcher protection appear to be ad hoc and without specified criteria of success. An examination of the recorded entries in the researcher protection registry could have led to changes in its administration as an alternative to its total abolition. Conclusions: In future opt-out systems, there should be focus on monitoring register practices and the purpose and criteria for evaluation must be defined prior to implementation.
Changing the home literacy environment through participation in family literacy programmes
Authors: Swain Jon Michael , Cara Olga
Published: December 2017

This paper presents findings from a study of family literacy provision in England and focuses on the effects of family literacy programmes on the home literacy environment. The fieldwork took place between September 2013 and December 2014 and involved 27 school-based programmes for pupils aged between 5 and 7, and their parents. The study used mixed methods, which involved observations of family literary sessions, a quantitative pre- and post-survey of 118 parents, and pre- and post-telephone qualitative interviews with a sub-sample of 24 parents. Building on previous theoretical work, the study conceptualises the home literacy environment into four areas (family resources; parental literacy behaviours and attitudes; parental beliefs and understandings; and family literacy activities and practices). The paper develops understandings of how parents translate and implement messages from family literacy into the home setting, and it shows how participation in these programmes leads to changes in family literacies across all four areas identified.
Adding ‘something more’ to looking: the interaction of artefact, verbiage and visitor in museum exhibitions
Authors: Blunden Jennifer
Published: December 2017

Around the world, museums dedicate enormous resources to developing exhibitions with the aim of making their collections and knowledge accessible to broad public audiences. Interpretive texts, both spoken and written, play an important role in this endeavour, underpinned by the belief that they will add ‘something more’ to the experience gained by looking alone. But is this belief justified? This article draws on recent theoretical developments in systemic functional linguistics (SFL) and multimodal semiotics to explore the complexity of meanings and relations involved in the interaction between (verbal) text, displayed artefact and visitor in an art exhibition and a history exhibition. Focusing on two key dimensions, vergence and presence, it shows how the texts work in very different ways to shape visitor experience, both in terms of scaffolding the interaction and in adding meaning to the encounter. It proposes the idea of ‘verbal vectors’ that are gradable in strength as a feature that explicitly ‘motivates’ visitors to look at the displayed artefacts and the idea of ‘shell’ vectors as a particular feature of texts in art exhibitions.
Why Should the Republicans Pray for Rain? Electoral Consequences of Rainfall Revisited
Authors: Horiuchi Yusaku , Kang Woo Chang
Published: December 2017

Existing studies—most importantly, Gomez, Hansford, and Krause—provide empirical support for an idea often embraced by popular media: The vote share of the Republican Party (as the percentage of total votes) increases when it rains, because the magnitude of decrease in turnout is larger among Democratic vis-à-vis Republican supporters. Considering the compositional nature of aggregated data, we show that the alleged Republican advantage derives in part from an increase in the number of votes for the Republican Party. Based on the extensive literature of psychology and related fields, we provide a possible interpretation of this counter-intuitive empirical finding. Methodologically, our evidence suggests that researchers must be alert when using rainfall as an instrument to estimate the causal effects of voter turnout on electoral outcome.
Neuropsychiatric Profile in Early Versus Late Onset Alzheimer’s Disease
Authors: Ferreira Maria do Céu , Abreu Maria João , Machado Célia , Santos Beatriz , Machado Álvaro , Costa Ana Sofia
Published: December 2017

Background:

The aim of this study was to investigate the frequency and severity of neuropsychiatric symptoms (NPS) in patients with early onset Alzheimer’s disease (EAOD) and late onset AD (LOAD).

Methods:

Patients were selected from a specialized memory outpatient clinic. The Mini-Mental State Examination, the Neuropsychiatric Inventory (NPI), and the Global Deterioration Scale results were analyzed.

Results:

By comparing EOAD (n = 35) and LOAD (n = 35) patients, no significant differences were found in clinical or demographic variables, matched for sex, education, and disease severity. There were no differences between groups in total NPI frequency or severity scores. The most common NPS were irritability, apathy, anxiety, and depression. We found an association of NPI scores with disease severity and duration, which was more specific in patients with LOAD and was also associated with the presence of delusions and hallucinations.

Conclusion:

Despite subtle differences, NPS is considered important in the assessment of patients with AD, regardless of the age of onset.
Encoding and Decoding Black and White Cultural Capitals: Black Middle-Class Experiences
Authors: Meghji Ali
Published: December 2017

Drawing upon 23 qualitative interviews, and ethnographic work in London, this article explores how black middle-class individuals in the UK decode forms of middle-class cultural capital. This decoding is two staged. Firstly, black middle-class individuals often decode dominant or ‘traditional’ middle-class cultural capital as white. This involves a recognition that certain forms of middle-class cultural capital are marked as racially exclusive, and are reproduced and recognised in ‘white spaces’. Secondly, black middle-class individuals also decode alternative forms of cultural capital as woven into a greater project of racial uplift. Such alternative forms of cultural capital are defined as ‘black cultural capital’, and tend to be based around fulfilling a cultural politics of black representation.
Mobile Voices: Design as a method to explore the possibilities and limitations of community participation
Authors: Brough Melissa , Lapsansky Charlotte , Gonzalez Carmen , Stokes Benjamin , Bar François
Published: December 2017

Despite the growing significance of mobile devices, especially among marginalized communities, there are few explorations of how participatory design (PD) can be applied to mobile communication technologies. This case study of Mobile Voices (VozMob) explores a community-based approach to PD and its potential to promote the participation of groups typically marginalized from the design process, and to empower users. VozMob is a mobile platform that was codesigned with and for immigrant workers and organizers to facilitate the online publishing of multimedia stories about their lives and their social justice efforts. Through collective visualization methods, observation, and interviews, this study investigates the factors that enabled or hindered meaningful user participation in the VozMob design process. Significant differences emerged between participants’ experiences of the design process, which allow for the exploration of themes related to technology appropriation, design ownership, and power sharing in collaborative processes. Our findings reveal that a community-based approach to PD can shed light on the degree to which—and how—collaborative design and equitable participation is possible through mobile media.

Published: December 2017

Background

The National Wilms Tumor Study (NWTS) approach to treating stage III favorable-histology Wilms tumor (FHWT) is Regimen DD4A (vincristine, dactinomycin, and doxorubicin) and radiation therapy. Further risk stratification is required to improve outcomes and reduce late effects. We evaluated clinical and biologic variables for patients with stage III FHWT without combined loss of heterozygosity (LOH) at chromosomes 1p and 16q treated in the Children’s Oncology Group protocol AREN0532.

Methods

From October 2006 to August 2013, 588 prospectively treated, centrally reviewed patients with stage III FHWT were treated with Regimen DD4A and radiation therapy. Tumor LOH at 1p and 16q was determined by microsatellite analysis. Ineligible patients (n = 5) and those with combined LOH 1p/16q (n = 40) were excluded.

Results

A total of 535 patients with stage III disease were studied. Median follow-up was 5.2 years (range, 0.2 to 9.5). Four-year event-free survival (EFS) and overall survival estimates were 88% (95% CI, 85% to 91%) and 97% (95% CI, 95% to 99%), respectively. A total of 58 of 66 relapses occurred in the first 2 years, predominantly pulmonary (n = 36). Eighteen patients died, 14 secondary to disease. A better EFS was associated with negative lymph node status ( P < .01) and absence of LOH 1p or 16q ( P < .01), but not with gross residual disease or peritoneal implants. In contrast, the 4-year EFS was only 74% in patients with combined positive lymph node status and LOH 1p or 16q. A total of 123 patients (23%) had delayed nephrectomy. Submitted delayed nephrectomy histology showed anaplasia (n = 8; excluded from survival analysis); low risk/completely necrotic (n = 7; zero relapses), intermediate risk (n = 63; six relapses), and high-risk/blastemal type (n=7; five relapses).

Conclusion

Most patients with stage III FHWT had good EFS/overall survival with DD4A and radiation therapy. Combined lymph node and LOH status was highly predictive of EFS and should be considered as a potential prognostic marker for future trials.
A Blood Bank Model with Perishable Blood and Demand Impatience
Authors: Bar-Lev Shaul K. , Boxma Onno , Mathijsen Britt , Perry David
Published: December 2017

We consider a stochastic model for a blood bank, in which amounts of blood are offered and demanded according to independent compound Poisson processes. Blood is perishable, i.e., blood can only be kept in storage for a limited amount of time. Furthermore, demand for blood is impatient, i.e., a demand for blood may be canceled if it cannot be satisfied soon enough. For a range of perishability functions and demand impatience functions, we derive the steady-state distributions of the amount of blood kept in storage, and of the amount of demand for blood (at any point in time, at most one of these quantities is positive). Under certain conditions we also obtain the fluid and diffusion limits of the blood inventory process, showing in particular that the diffusion limit process is an Ornstein-Uhlenbeck process.

Does precedence trump in the origins of confidentiality?
Authors: Woolcock Mark
Published: December 2017

Good clinical practice has to be entwined with good ethical practice. Therefore, it follows that the clinical acumen of a modern paramedic develops at the same rate as their moral and ethical practice. As a newer profession, paramedics have relied on rules and codes from others to help maintain this balance, but their ancient and basic structure fails to address the nuances of modern practice. The paramedic profession has required a heuristic approach, as well as relying on the precedent of modern laws and codes, to underpin practice while simultaneously recognising the limitations of oath-based principles. This response has been necessary to address the increasingly complex and complicated situations paramedics encounter in their clinical environment.
The impact of age on major orthopaedic trauma
Authors: Herron J. , Hutchinson R. , Lecky F. , Bouamra O. , Edwards A. , Woodford M. , Eardley W. G. P.
Published: December 2017

Aims

To compare the early management and mortality of older patients sustaining major orthopaedic trauma with that of a younger population with similar injuries.

Patients and Methods

The Trauma Audit Research Network database was reviewed to identify eligible patients admitted between April 2012 and June 2015. Distribution and severity of injury, interventions, comorbidity, critical care episodes and mortality were recorded. The population was divided into young (64 years or younger) and older (65 years and older) patients.

Results

Of 142 765 adults sustaining major trauma, 72 942 (51.09 %) had long bone or pelvic fractures and 45.81% of these were > 65 years old. Road traffic collision was the most common mechanism in the young (40.4%) and, in older people, fall from standing height (80.4%) predominated. The 30 day mortality in older patients with fractures is greater (6.8% versus 2.5%), although critical care episodes are more common in the young (18.2% versus 9.7%). Older people are less likely to be admitted to critical care beds and are often managed in isolation by surgeons. Orthopaedic surgery is the most common admitting and operating specialty and, in older people, fracture surgery accounted for 82.1% of procedures.

Conclusion

Orthopaedic trauma in older people is associated with mortality that is significantly greater than for similar fractures in the young. As with the hip fracture population, major trauma in the elderly is a growing concern which highlights the need for a review of admission pathways and shared orthogeriatric care models.

Minimally invasive surgery for adolescent idiopathic scoliosis
Authors: de Bodman C. , Miyanji F. , Borner B. , Zambelli P-Y. , Racloz G. , Dayer R.
Published: December 2017

Aims

The aim of this study was to report a retrospective, consecutive series of patients with adolescent idiopathic scoliosis (AIS) who were treated with posterior minimally invasive surgery (MIS) with a mean follow-up of two years (sd 1.4; 0.9 to 0 3.7). Our objectives were to measure the correction of the deformity and record the peri-operative morbidity. Special attention was paid to the operating time (ORT), estimated blood loss (EBL), length of stay (LOS) and further complications.

Patients and Methods

We prospectively collected the data of 70 consecutive patients with AIS treated with MIS using three incisions and a muscle-splitting approach by a single surgeon between June 2013 and February 2016 and these were retrospectively reviewed. There were eight male and 62 female patients with a mean age of 15 years (sd 4.5 ) with a mean body mass index of 19.8 kg/m2 (sd 5.4). The curves were classified according to Lenke; 40 curves were type 1, 15 were type 2, three were type 3, two were type 4, eight were type 5 and two were type 6.

Results

The mean primary Cobb angle was corrected from 58.9° (sd 12.6°) pre-operatively to 17.7° (sd 10.2°) post-operatively with a mean correction of 69% (sd 20%, p < 0.001). The mean kyphosis at T5 to T12 increased from 24.2° (sd 12.2°) pre-operatively to 30.1° (sd 9.6°, p < 0.001) post-operatively. Peri-operative (30 days) complications occurred in three patients(4.2%): one subcutaneous haematoma, one deep venous thrombosis and one pulmonary complication. Five additional complications occurred in five patients (7.1%): one superficial wound infection, one suture granuloma and three delayed deep surgical site infections. The mean ORT was 337.1 mins (sd 121.3); the mean EBL was 345.7 ml (sd 175.1) and the mean LOS was 4.6 days (sd 0.8).

Conclusion

The use of MIS for patients with AIS results in a significant correction of spinal deformity in both the frontal and sagittal planes, with a low EBL and a short LOS. The rate of peri-operative complications compares well with that following a routine open technique. The longer term safety and benefit of MIS in these patients needs to be evaluated with further follow-up of a larger cohort of patients. Cite this article: Bone Joint J 2017;99-B:1651–7.
An analysis of 30-day mortality after weekend versus weekday elective joint arthroplasty in England and Wales
Authors: Hunt L. P. , Blom A. , Wilkinson J. M.
Published: December 2017

Aims

To investigate whether elective joint arthroplasty performed at the weekend is associated with a different 30-day mortality versus that performed between Monday and Friday.

Patients and Methods

We examined the 30-day cumulative mortality rate (Kaplan-Meier) for all elective hip and knee arthroplasties performed in England and Wales between 1st April 2003 and 31st December 2014, comprising 118 096 episodes undertaken at the weekend and 1 233 882 episodes performed on a weekday. We used Cox proportional-hazards regression models to assess for time-dependent variation and adjusted for identified risk factors for mortality.

Results

The cumulative 30-day mortality for hip arthroplasty was 0.15% (95% confidence interval (CI) 0.12 to 0.19) for patients operated on at the weekend versus 0.20% (95% CI 0.19 to 0.21) for patients undergoing surgery during the normal working week. For knee arthroplasty, the cumulative 30-day mortality was 0.14% (95% CI 0.11 to 0.17) for weekend-operated patients versus 0.18% (95% CI 0.17 to 0.19) for weekday-operated patients. These differences were independent of any differences in patient age, gender, American Society of Anaesthesiologists grade, surgeon seniority, surgical and anaesthetic practices, and thromboprophylaxis choice in weekend versus weekday-operated patients.

Conclusion

The 30-day mortality rate after elective joint arthroplasty is low. Surgery performed at the weekend is associated with lower post-operative mortality versus operations performed on a weekday. Cite this article: Bone Joint J 2017;99-B:1618–28.
Quantifying the ‘law of diminishing returns’ in magnetically controlled growing rods
Authors: Ahmad A. , Subramanian T. , Panteliadis P. , Wilson-Macdonald J. , Rothenfluh D A. , Nnadi C.
Published: December 2017

Aims

Magnetically controlled growing rods (MCGRs) allow non-invasive correction of the spinal deformity in the treatment of early-onset scoliosis. Conventional growing rod systems (CGRS) need repeated surgical distractions: these are associated with the effect of the ‘law of diminishing returns’. The primary aim of this study was to quantify this effect in MCGRs over sequential distractions.

Patients and Methods

A total of 35 patients with a maximum follow-up of 57 months were included in the study. There were 17 boys and 18 girls with a mean age of 7.4 years (2 to 14). True Distraction (TD) was determined by measuring the expansion gap on fluoroscopy. This was compared with Intended Distraction (ID) and expressed as the ‘T/I’ ratio. The T/I ratio and the Cobb angle were calculated at several time points during follow-up.

Results

The mean follow-up was 30 months (6 to 57). There was a significant decrease in the mean T/I ratio over time (convex rod at 3 months 0.81, sd 0.58 vs 51 months 0.17, sd 0.16, p = 0.0001; concave rod at 3 months 0.93, sd 0.67 vs 51 months 0.18, sd 0.15, p = 0.0001). A linear decline of the mean T/I ratios was noted for both convex rods (r2 = 0.90, p = 0.004) and concave rods (r2 = 0.81, p = 0.015) over 51 months. At the 24-month follow-up stage, there was a significant negative correlation between the mean T/I ratio of the concave rod with weight (r = -0.59, p = 0.01), age (r = -0.59, p = 0.01), and BMI of the child (r = -0.54, p = 0.01).

Conclusions

The ‘law of diminishing returns’ is also seen after serial distraction using MCGR. Compared to previously published data for CGRS, there is a gradual linear decline rather than a rapid initial decline in lengthening. In older, heavier children a reduced distraction ratio in the concave rod of the MCGR device is noted over time. Cite this article: Bone Joint J 2017;99-B:1658–64.
The minimum follow-up required for radial head arthroplasty
Authors: Laumonerie P. , Reina N. , Kerezoudis P. , Declaux S. , Tibbo M. E. , Bonnevialle N. , Mansat P.
Published: December 2017

Aims

The primary aim of this study was to define the standard minimum follow-up required to produce a reliable estimate of the rate of re-operation after radial head arthroplasty (RHA). The secondary objective was to define the leading reasons for re-operation.

Materials and Methods

Four electronic databases, between January 2000 and March 2017 were searched. Articles reporting reasons for re-operation (Group I) and results (Group II) after RHA were included. In Group I, a meta-analysis was performed to obtain the standard minimum follow-up, the mean time to re-operation and the reason for failure. In Group II, the minimum follow-up for each study was compared with the standard minimum follow-up.

Results

A total of 40 studies were analysed: three were Group I and included 80 implants and 37 were Group II and included 1192 implants. In Group I, the mean time to re-operation was 1.37 years (0 to 11.25), the standard minimum follow-up was 3.25 years; painful loosening was the main indication for re-operation. In Group II, 33 Group II articles (89.2%) reported a minimum follow-up of < 3.25 years.

Conclusion

The literature does not provide a reliable estimate of the rate of re-operation after RHA. The reproducibility of results would be improved by using a minimum follow-up of three years combined with a consensus of the definition of the reasons for failure after RHA.

The bully chamber: Creation of funhouse selves from distorted media
Authors: Shires Jeff , Orgel Nel
Published: December 2017

This article considers how the technological changes have facilitated the establishment of a sense of ‘ressentiment’ in modern political cultures. This is the unease created when someone believes they have been injured by another but feel impotent to act. While technologies have developed at a startling rate, society’s ability to deal with them has not kept up. Consequently, neo-liberal economic principles and political narratives have distorted the culture practices as a range of agencies (political, economic, technology) have become elitist and self-serving. Individual forms of identity are undermined by a surfeit of information in which online gatekeepers (Google, Facebook, Twitter) use algorithms that synthesize real with virtual emotional values. These distortions are now being made tangible with the election of right-wing populists such as Donald Trump and the genuine sense of popular dislocation that contributed to the UK Brexit vote.
Peningkatan Ibadah Mahasiswa Tuli dengan Praktik Salat Bisindo
Authors: Siddicq Achmad
Published: December 2017

Prayer is an obligation for every Muslim. It consIst of speech and movement. The speech aspect of the prayer has been a problem for the deaf. They generally fail to learn and practice the prayer correctly becuase of this speech barrier. This paper is based on an action research designed to help deaf students to learn the prayer better.  The action research was designed by visualizing the Arabic speech into the Indonesian Sign Language (BISINDO). The reasearch shows that the visualization of prayer speech into the Indonesian sign language is more effective than using the Arabic speech-based prayer learning. In addition, this program can affect the daily practice of prayer among deaf students.[Ibadah salat, yang merupakan kewajiban bagi setiap orang Islam, di ditunaikan dengan ucapan dan perbuatan. Unsur ucapan dalam salat menjadi hambatan bagi para Tuli. Karena gaya belajar berbasis visual merupakan cara yang paling optimal bagi Tuli untuk belajar, maka cara yang tepat dan aksesibel dalam belajar salat adalah dengan memvisualisasikan bacaan salat yang berBahasa Arab menjadi Bahasa Isyarat Indonesia (BISINDO). Artikel ini menjelaskan bagaimana cara meningkatkan praktik tata cara salat untuk mahasiswa Tuli melalui program pelatihan salat berbasiskan BISINDO. Penelitian tindakan (action research) yang menjadi dasar tulisan ini membuktikan bahwa visualisasi bacaan salat menjadi bahasa isyarat lebih efektif daripada menggunakan Bahasa Arab secara oral.

Vitamin D (VD) and vitamin C (VC) have been recognized as essential elements for human health.  Animal models, especially mouse models, have been widely used in the study of VD and VC. This study is to investigate how VD and VC interact at molecular level using whole genome expression profiles from spleens of 111 mouse strains and livers from 40 mouse strains. We first identified the genes that are closely correlated to vitamin D receptor (Vdr) and gulonolactone oxidase (Lgo). We next analyzed the potential molecular pathways of Vdrand Lgo correlated genes and examined how these two sets of pathways are connected in liver and spleen. Our results indicated that Vdrand Lgo associate to distinct groups of genes. While most of genes are not the same, a few of them are associated to both Vdrand Lgo.  Our gene network construction suggests that there are interactions between Vdrand Lgopathways.  Our work laid down the foundation for future study of the interactions between VD and VC and revealed the potential bias when using animals for the study of VD or VC, as humans do not produce VC.

Many studies have been examined the association of platelet glycoprotein (GP) Ia C807T polymorphism with ischemic stroke (IS) susceptibility. However, the results of these studies are inconsistent. To further assess the effects of GP Ia C807T polymorphism on the risk of IS, a meta-analysis was performed in a separate ethnic group. Relevant studies were identified using PubMed and Chinese databases through January 2017. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the associations. Finally, 13 studies contained 2438 IS cases and 2308 controls included. In the total analyses, a significantly elevated risk of IS was associated with all variants of GP Ia C807T in the Chinese population (T vs C: OR = 1.24, 95% CI = 1.09-1.40; TT vs CC: OR = 1.59, 95% CI = 1.17-2.15; TT and CT combined vs CC: OR = 1.32, 95% CI = 1.09-1.59; TT vs CC and CT: OR = 1.35, 95% CI = 1.04-1.76). In the subgroup analyses stratified by ethnicity and geographic areas, it revealed the significant results in Chinese Han and in South China. This meta-analysis provides the evidence that GP Ia C807T polymorphism may contribute to the IS development in the Chinese population, especially in South China, and further studies in other ethic groups are required for definite conclusions.
