    The present article reports two experiments examining the impact of recollecting emotionally valenced autobiographical memories on subsequent working memory (WM) task performance. Experiment 1 found that negatively valenced recollection significantly disrupted performance on a supra-span spatial WM task. Experiment 2 replicated and extended these findings to a verbal WM task (digit recall), and found that both negative and positive autobiographical recollections had a detrimental effect on verbal WM. In addition, we observed that these disruptive effects were more apparent on early trials, immediately following autobiographical recollection. Overall, these findings show that both positive and negative affect can disrupt WM when the mood-eliciting context is based on autobiographical memories. Furthermore, these results indicate that the emotional disruption of WM can take place across different modalities of WM (verbal and visuo-spatial).

    Reduced fetal movement is a worrisome common complaint, not only for mothers but also for the attending medical personnel. The aim of this study was to analyse the pregnancy outcomes of women who presented primarily with reduced fetal movements (RFM). A retrospective study was performed based on patients' perception alone. Obstetric, past medical history, current presentation and outcomes of pregnancy were analysed. A total of 230 case notes were reviewed, with the majority being primigravidae. Less than half (48.7%) of the women had spontaneous labour, 45.7% had induction and 5.6% had elective caesarean section. There were no maternal complications in 97.4% (n = 224) of them. About 0.9% (n = 2) and 1.7% (n = 4) had primary postpartum haemorrhage and extended perineal tear, respectively. Although there was no major neonatal mortality and morbidity, until a randomised trial with a significant sample is conducted in the management of RFM, careful selections for elective delivery or conservative management would prevent untoward complications.

    This paper details the study on the changes in riding behaviour, such as changes in speed as well as the brake force and throttle force applied, when motorcyclists ride over a curve section road using an instrumented motorcycle. In this study, an instrumented motorcycle equipped with various types of sensors, on-board cameras, and data loggers, was developed in order to collect the riding data on the study site. Results from the statistical analysis showed that riding characteristics, such as changes in speed, brake force, and throttle force applied, are influenced by the distance from the curve entry, riding experience, and travel mileage of the riders. A structural equation modeling was used to study the impact of these variables on the change of riding behaviour in curve entry section. Four regression equations are formed to study the relationship between four dependent variables, which are speed, throttle force, front brake force, and rear brake force applied with the independent variables.

    Trans-mesenteric hernia is a form of internal hernia which is an extremely rare cause of intestinal obstruction in adults compared with the pediatric population. It often presents with complications such as acute intestinal obstruction and peritonitis requiring immediate surgical intervention. We report a case of a 21-year-old woman who presented to us with an acute abdomen and peritonitis that required an immediate exploratory laparotomy. She was found to have a small congenital mesenteric defect with strangulated segment of ileum. Gangrenous portion of the ileum was resected and the congenital defect was closed. The patient made an uneventful recovery. The occurrence of trans-mesenteric hernia in adults is rare and difficult to be diagnosed clinically; thus, the patient's clinical features may lead to early surgical intervention in order to reduce morbidity and mortality.

    This study evaluated the effect of a Probiotic mouthrinse containing nisin, a bacteriocin extracted from Lactococcus lactis on dental plaque and gingivitis in young adult population. A group of 32 subjects were randomly assigned into two groups of 16 each. The first group started using the control mouthrinse (placebo) for 2 weeks followed by a washout period of 4 weeks. This group then used the test mouthrinse (Probiotic) for a further duration of 2 weeks. The second group followed a similar protocol as the first except that this group started with the test mouthrinse (Probiotic). Plaque Index (PI) and Gingival Index (GI) were recorded at baseline and after 2 weeks for each group. All subjects were given full mouth prophylaxis after each measurements. The results of this study showed that rinsing with Probiotic mouthrinse resulted in a statistically significant reduction of plaque accumulation and gingivitis compared to rinsing with placebo. The results indicated that Probiotic mouthrinse containing nisin had the potential of inhibiting plaque accumulation and was effective in reducing gingivitis.

    Human adipose tissue has been recognized as an alternative source of adult stem cells. The abundance and ease of harvest of adipose tissue has made it suitable for use in regenerative medicine and tissue engineering. Adipose-derived stem cells isolated from human adipose tissue are able to differentiate into several mesenchymal lineages and secrete growth factors that exhibit therapeutic potential. Protein profiles have been established using various isolation methods, which has expanded researchers’ understanding of adipose-derived stem cells in clinical applications. This review highlights the properties, isolation methods, immunophenotype and clinical applications of adipose-derived stem cells.

    We report a 21-year old female patient who presented with an 18-month history of a swelling in the distal phalanx of her right little finger. Although the history, clinical features and MRI were suggestive of a benign tumour or a tuberculous lesion, the histo-pathological examination of the swelling was reported as a conventional osteosarcoma. Osteosarcoma of the hand is very rare. This article highlights the possibility of a seemingly benign lesion seen in a routine clinic could well turn out to be malignant, and the need to maintain a high index of suspicion.

    Introduction: Accurate yet inexpensive methods for measuring free-living energy expenditure (EE) are
    much needed. The aim of this study was to determine the feasibility of heart-rate monitoring method
    (HRM) in measuring EE as compared to the established activity diary (AD) method. Methodology:
    Minute-by-minute HRM and an activity diary (AD) were used simultaneously in 34 young adults (18
    females, 16 males; mean age 21.5 ± 1.5 years). Estimates of the EE from HRM were based on individual
    calibration using the Flex-HR procedure while EE from AD were calculated using both individually
    measured and published energy cost of various activities. Total daily energy expenditure (TDEE) and its
    components (EE during sleep, during rest and during physical activity) were compared using Student
    paired-t tests. Results: TDEE from HRM method averaged 8.17 ± 2.00 MJ/day compared to 8.50 ±
    1.28 MJ/day from AD method. Although large intra-individual differences were found (ranging from
    -36.9% to 47.4%), there was no significant difference between the two methods (mean difference -3.6 ± 19.4%). The limits of agreement (mean ± 2SD) were -3.77 and 3.11 MJ/day. There were no significant
    differences for any of the TDEE components between the two methods, except for EE during sleep

    This exploratory study is part of an on-going project about digital cultures on ageism, anonymity, and gendering. An avatar is the graphical representation of the online user. The study investigates the avatars drawn by a group of 76 young adults studying in a local university. A face-to-face interview was conducted to ascertain the features drawn. Results show that the avatars are more characterized by the sexual features related to the body, face, clothes, and a major number of context elements. The females tend to represent themselves in greater detail than the males. The former created gendered identities for themselves according to their offline gender identity and social contexts. The study illustrates that the hand drawing is an effective tool that analyses the online representation in an unobtrusive way. The expressions of gendering show that gender is consciously constructed. Gendering of avatars does permeate the virtual world. This study is a valuable addition to the growing body of work on social interaction in cyberspace.

    For patients with acute respiratory distress syndrome (ARDS), mechanical ventilation (MV) is an essential therapy in the intensive care unit (ICU). Suboptimal PEEP levels in MV can cause ventilator induced lung injury, which is associated with increased mortality, extended ICU stay, and high cost. The ability to predict the outcome of respiratory mechanics in response to changes in PEEP would thus provide a critical advantage in personalising and improving care. Testing the potentially dangerous high pressures would not be required to assess their impact. A nonlinear autoregressive (NARX) model was used to predict airway pressure in 19 data sets from 10 mechanically ventilated ARDS patients. Patient-specific NARX models were identified from pressure and flow data over one, two, three, or four adjacent PEEP levels in a recruitment manoeuvre. Extrapolation of NARX model elastance functions allowed prediction of patient responses to PEEP changes to higher or lower pressures. NARX model predictions were more successful than those using a well validated first order model (FOM). The most clinically important results were for extrapolation up one PEEP step of 2cmH2O from the highest PEEP in the training data. When the NARX model was trained on one PEEP level, the mean RMS residual for the extrapolation PEEP level was 0.52 (90% CI: 0.47-0.57) cmH2O, compared to 1.50 (90% CI: 1.38-1.62) cmH2O for the FOM. When trained on four PEEP levels, the NARX result was 0.50 (90% CI: 0.42-0.58) cmH2O, and was 1.95 (90% CI: 1.71-2.19) cmH2O for the FOM. The results suggest that a full recruitment manoeuvre may not be required for the NARX model to obtain a useful estimate of the pressure waveform at higher PEEP levels. The methodology could thus allow clinicians to make informed decisions about ventilator PEEP settings while reducing the risk associated with high PEEP, and subsequent high peak airway pressures.

    Journal of Sports Science and Physical Education 5(2): 15-23, 2016 - This study was
    conducted to determine the relationship between lower body muscle architectures and lunges
    performance. Thirty recreationally active, untrained men (mean age = 22.21 ± 1.59 yrs old)
    were recruited and involved in two testing sessions; i) anthropometrics and muscle
    architecture, and ii) multiple-repetition maximum (RM) lunge test. Muscle thickness,
    pennation angle and fascicle length of vastus lateralis (VL), vastus medialis (VM), rectus
    femoris (RF) and biceps femoris (BF) were analysed using ultrasonography. Multiple-RM
    lunge testing was used as an estimation of 1RM lunges performance. Correlation analysis was
    used to determine the relationship between lower body muscle architectures and lunges
    performance calculated absolutely and relatively (1RM/body mass). The overall results
    showed that muscle thickness and pennation angle of all muscles were significantly positive
    correlated with lunges performance. However, fascicle length was shown to be negatively
    correlated with lunges performance. Findings of this study suggested the important for having
    thicker, more pennated and shorter fascicle of lower body muscle in enhancing lunges
    performances that is one of the most specific movements in sport.

    BACKGROUND: Multiple sclerosis (MS) is the most widespread disabling neurological condition in young adults around the world. The purpose of this study was to investigate the impact of explicit information (EI) on motor-sequence learning in MS patients.

    METHODS: Thirty patients with relapsing-remitting MS (RRMS), age: 29.5 (SD = 5.6) years and 30 healthy gender-, age-, and education-matched control group participants, age: 28.8 (SD = 6.0) years, were recruited for this study. The participants in the healthy group were then randomly assigned into an EI (n = 15) group and a no-EI (n = 15) group. Similarly, the participants in the control group were then randomly assigned into EI (n = 15) and no-EI (n = 15) groups. The participants performed a serial reaction time (SRT) task and reaction times. A retention test was performed after 48 hours.

    RESULTS: All participants reduced their reaction times across acquisition (MS group: 46.4 (SD = 3.3) minutes, P < 0.001, and healthy group: 39.4 (SD = 3.3) minutes, P < 0.001). The findings for the within-participants effect of repeated measures of time were significant (F(5.06, 283.7) = 71.33. P < 0.001). These results indicate that the interaction between group and time was significant (F(5.06, 283.7) = 6.44. P < 0.001), which indicated that the reaction time in both groups was significantly changed between the MS and healthy groups across times (B1 to B10). The main effect of the group (MS and healthy) (F(1, 56) = 22.78. P < 0.001) and also the main effect of no-EI vs EI (F(1, 56) = 4.71. P < 0.001) were significant.

    CONCLUSION: This study demonstrated that that RRMS patients are capable of learning new skills, but the provision of EI prior to physical practice is deleterious to implicit learning. It is sufficient to educate MS patients on the aim and general content of the training and only to provide feedback at the end of the rehabilitative session.

    A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year. The burden of disease was significant in the adult population; 74.5% of patients with RHD were female, of which 77.1% were in the reproductive age group of 15-45 years old. Rheumatic mitral valve disease constituted almost half (46.7%) of all mitral valve repairs, ranging from 44.8 - 55.8 patients per year from 1997 - 2003. From 2010-2012, mitral valve interventions increased to 184 per year, of which 85.7% were mitral valve repair. In children with ARF, 25.4% - 41.7% had past history of rheumatic fever or RHD. In patients with rheumatic mitral valve disease undergoing surgical or medical interventions, only 6% reported history of ARF, none had history of GABHS pharyngitis or antibiotic prophylaxis. Only 44.7% of patients with RHD on follow-up were on intramuscular benzathine penicillin prophylaxis. Overall, there is scarcity of publications on ARF and RHD in Malaysia. Priority areas for research include determination of the incidence and prevalence of ARF and RHD, identification of high-risk populations, evaluation on the implementation and adherence of secondary preventive measures, identification of subclinical RHD especially amongst the high-risk population, and a surveillance system to monitor and evaluate preventive measures, disease progression and outcomes.

    This study compared bite force in adults older than 60 years with that of young adults. The participants were 20 healthy adults (9 men) older than 60 years (median age, 66 years) and 44 healthy young adults (22 men; age range, 18-25 years; median age, 22 years) at the International Medical University, Malaysia. All participants had at least 20 teeth, and bite force was measured and evaluated using the Dental Prescale system. Average (SD) bite force was 420.5 (242.0) N for the older adults and 541.4 (296.3) N for the young adults. Although mean bite force was higher for the young adults, the difference was not significant. These findings suggest that bite force is unaffected by age in adults with adequate dentition.

    This study investigates the mediating role of identity confusion and materialism in the relationship between social networking site (SNS) excessive usage and online compulsive buying among young adults. A total of 501 SNS users aged 17 to 23 years (M = 19.68, SD = 1.65) completed an online survey questionnaire. A serial multiple mediator model was developed and hypotheses were tested using structural equation modeling. The results showed that excessive young adult SNS users had a higher tendency toward compulsive buying online. This was partly because they experienced higher identity confusion and developed higher levels of materialism. Targeted psychological interventions seeking to gradually increase identity clarity to buffer the detrimental effects of SNS usage and identity confusion in young adults are suggested.

    Prosthetic alignment is an essential process to rehabilitate patients with amputations. This study presents, for the first time, an invented device to read and record prosthesis alignment data. The digital device consists of seven main parts: the trigger, internal shaft, shell, sensor adjustment button, digital display, sliding shell, and tip. The alignment data were read and recorded by the user or a computer to replicate prosthesis adjustment for future use or examine the sequence of changes in alignment and its effect on the posture of the patient. Alignment data were recorded at the anterior/posterior and medial/lateral positions for five patients. Results show the high level of confidence to record alignment data and replicate adjustments. Therefore, the device helps patients readjust their prosthesis by themselves, or prosthetists to perform adjustment for patients and analyze the effects of malalignment.
