Hereditary right Jacobson radicals of type-1(e) and 2(e) for right near-rings
Authors: Rao Ravi Srinivasa , Prasad K. Siva 
Published: August 2013

Abstract
Near-rings considered are right near-rings. In this paper two more radicals, the right Jacobson radicals of type-1(e) and 2(e), are introduced for near-rings. It is shown that they are Kurosh-Amitsur radicals (KAradicals) in the class of all near-rings and are ideal-hereditary radicals in the class of all zero-symmetric near-rings. Different kinds of examples are also presented.

Authors: Cholamjiak Prasit , Je Cho Yeol , Suantai Suthep 
Published: August 2013

Abstract
In this paper, we first prove a path convergence theorem for a nonexpansive mapping in a reflexive and strictly convex Banach space which has a uniformly Gˆateaux differentiable norm and admits the duality mapping jφ, where φ is a gauge function on [0,∞). Using this result, strong convergence theorems for common fixed points of a countable family of nonexpansive mappings are established.
Rad-⊕-Supplemented Modules
Authors: Türkmen Ergül 
Published: August 2013

Abstract
In this paper we provide various properties of Rad-⊕-supplemented modules. In particular, we prove that a projective module M is Rad- ⊕-supplemented if and only if M is ⊕-supplemented, and then we show that a commutative ring R is an artinian serial ring if and only if every left R-module is Rad-⊕-supplemented. Moreover, every left R-module has the property (P*) if and only if R is an artinian serial ring and J2 = 0, where J is the Jacobson radical of R. Finally, we show that every Rad-supplemented module is Rad-⊕-supplemented over dedekind domains.

Abstract Let A(p) denote the class of functions of the form f(z) = zp Σ∞k=1+p akzk (p ∈ N = {1, 2, 3,...}) which are analytic in the open unit disk U = {z : z ∈ C and |z| < 1} By making use of the Noor integral operator, we obtain some interesting properties of multivalent analytic functions.
If I want to perform better, then how should I feel?
Authors: Lane Andrew M. 
Published: August 2013

Abstract
Research indicates that emotions are predictive of sports performance. The application of emotion research to practice is that intervention strategies can be used to change emotions to enhance performance. The present study examined emotional profiles associated with successful performance. A review of studies indicate that there are general trends, that is, high activation emotions such as excitement and vigor tend to associate with good performance and low activation unpleasant emotions such as depression and dejection tend to associate with poor performance. Studies show mixed results for high activation unpleasant emotions (anger and anxiety). Athletes like to feel emotions that can be functional, and so some athletes will seek to increase or sustain relatively high levels of anger or anxiety if they believe they are helpful for performance. It is proposed that practitioners identify individual emotion-performance relationships and examine underlying beliefs associated with each emotion.
Emotional intelligence as a moderator in the relationship between negative emotions and emotional exhaustion among employees in service sector occupations
Authors: Szczygieł Dorota , Bazińska Róża 
Published: August 2013

AbstractTraditionally, most of the research on occupational burnout has focused on organizational stressors, such as workload and time pressure, and has overlooked the emotional nature of customer service work and its effect on burnout. This study was designed to examine the effects of individuals’ affective traits (i.e., dispositional affectivity and emotional intelligence) and affective states (i.e., emotions experienced at work) on burnout. The main hypothesis of this study was that emotional intelligence acts as a moderator in the relationship between negative emotions felt by employees during their interactions with clients and emotional exhaustion. A total of 137 service sector employees rated the extent to which they felt four positive emotions (i.e., contentment, enthusiasm, joy, and liking) and four negative emotions (i.e., irritation, annoyance, antipathy, and anger) while interacting with clients. The results indicated that negative affectivity was significantly associated with higher levels of emotional exhaustion, whereas high positive affectivity showed the reverse pattern. It was also observed that employees who declared greater intensity of negative emotions reported more symptoms of emotional exhaustion. However, as predicted, this effect was observed only among employees who were low in the trait of emotional intelligence. Negative emotions and emotional exhaustion were unrelated among employees who were high in trait emotional intelligence.
Personality Traits and Subjective Health in Retirement Age – The Role of Personal Resources
Authors: Finogenow Maria 
Published: August 2013

Abstract
The aim of the study was to analyse the relationship between five-factor personality traits and subjective health in retirement age, including the mediating role of personal resources. The sample comprised of 240 older adults approaching or of retirement age; aged 55-70 (M = 60.1 years). Subjective health was negatively associated with neuroticism and positively associated with extraversion and openness to experiences. Multiple mediation analyses indicated that personal resources (especially the sense of meaningfulness) mediated most of the analyzed associations between personality and subjective health. For conscientiousness suppressive effects were found
Recognition of facial expressions of emotions in schizophrenia
Authors: Łosiak Władysław , Siedlecka Joanna 
Published: August 2013

Abstract
Deficits in recognition of facial expressions of emotions are considered to be an important factor explaining impairments in social functioning and affective reactions of schizophrenic patients. Many studies confirmed such deficits while controversies remained concerning the emotion valence and modality. The aim of the study was to explore the process of recognizing facial expressions of emotion in the group of schizophrenic patients by analyzing the role of emotion valence, modality and gender of the model. Results of the group of 35 patients and 35 matched controls indicate that while schizophrenic patients show general impairment in recognizing facial expressions of both positive and the majority of negative emotions, there are differences in deficits for particular emotions. Expressions also appeared to be more ambiguous for the patients while variables connected with gender were found less significant.

Published: August 2013

The aim of the study was to evaluate the effect of Leucas zeylanica against oxidative stress on hepatic tissue. Oxidative stress was induced by exposing hepatic tissue to ethanol and Fentons reagent (H2O2+FeSO4). The effect of oxidative stress on liver also was evaluated by the determination of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activity and the levels of lipid peroxide (LPO). The antioxidative activity of L. zeylanica was determined by estimating it ability to inhibit the hepatic levels of lipid peroxide (LPO), as indicator of oxidative stress. Concomitantly, the antioxidant phytochemicals such as polyphenols and flavonoids were assessed against pyrogallol and quercetin standards. The ALT and AST activities and the levels of LPO of hepatic tissue were significantly increased by oxidative stress. L. zeylanica pretreatment, however, significantly repressed the oxidative stress on hepatic tissue, as indicated by the decreased activities of ALT and AST enzymes and levels of LPO. Analyses of the phytochemicals revealed that the extract of L. zeylanica contained substantial amounts of polyphenols (74.32 ± 4.6 µg of pyrogallol equivalent/mg) and flavonoids (15.69 ± 2.2 µg quercetin equivalent/mg of extract). Finally, the results of the present study demonstrated the presence of antioxidant phytochemicals, including polyphenols and flavonoids in L. zeylanica and henceforth conferred protection against ethanol and H2O2-induced oxidative stress on hepatic tissue.DOI: http://dx.doi.org/10.3329/icpj.v2i9.16076 International Current Pharmaceutical Journal, August 2013, 2(9): 148-151
Clinical Examination Results in Individuals With Functional Ankle Instability and Ankle-Sprain Copers
Authors: Wright Cynthia J. , Arnold Brent L. , Ross Scott E. , Ketchum Jessica , Ericksen Jeffrey , Pidcoe Peter 
Published: August 2013

Context:
Why some individuals with ankle sprains develop functional ankle instability and others do not (ie, copers) is unknown. Current understanding of the clinical profile of copers is limited.

Objective:
To contrast individuals with functional ankle instability (FAI), copers, and uninjured individuals on both self-reported variables and clinical examination findings.

Design:
Cross-sectional study.

Setting:
Sports medicine research laboratory.

Patients or Other Participants:
Participants consisted of 23 individuals with a history of 1 or more ankle sprains and at least 2 episodes of giving way in the past year (FAI: Cumberland Ankle Instability Tool [CAIT] score = 20.52 ± 2.94, episodes of giving way = 5.8 ± 8.4 per month), 23 individuals with a history of a single ankle sprain and no subsequent episodes of instability (copers: CAIT score = 27.74 ± 1.69), and 23 individuals with no history of ankle sprain and no instability (uninjured: CAIT score = 28.78 ± 1.78).

Intervention(s):
Self-reported disability was recorded using the CAIT and Foot and Ankle Ability Measure for Activities of Daily Living and for Sports. On clinical examination, ligamentous laxity and tenderness, range of motion (ROM), and pain at end ROM were recorded.

Main Outcome Measure(s):
Questionnaire scores for the CAIT, Foot and Ankle Ability Measure for Activities of Daily Living and for Sports, ankle inversion and anterior drawer laxity scores, pain with palpation of the lateral ligaments, ankle ROM, and pain at end ROM.

Results:
Individuals with FAI had greater self-reported disability for all measures (P &lt; .05). On clinical examination, individuals with FAI were more likely to have greater talar tilt laxity, pain with inversion, and limited sagittal-plane ROM than copers (P &lt; .05).

Conclusions:
Differences in both self-reported disability and clinical examination variables distinguished individuals with FAI from copers at least 1 year after injury. Whether the deficits could be detected immediately postinjury to prospectively identify potential copers is unknown.
Side-Alternating Vibration Training for Balance and Ankle Muscle Strength in Untrained Women
Authors: Spiliopoulou Styliani I. , Amiridis Ioannis G. , Tsigganos Georgios , Hatzitaki Vassilia 
Published: August 2013

Context:
Side-alternating vibration (SAV) may help reduce the risk of falling by improving body balance control. Such training has been promoted as a strength-training intervention because it can increase muscle activation through an augmented excitatory input from the muscle spindles.

Objective:
To determine the effect of SAV training on static balance during 3 postural tasks of increasing difficulty and lower limb strength.

Design:
Randomized controlled clinical trial.

Setting:
Laboratory.

Patients or Other Participants:
A total of 21 healthy women were divided into training (n = 11; age = 43.35 ± 4.12 years, height = 169 ± 6.60 cm, mass = 68.33 ± 11.90 kg) and control (n = 10; age = 42.31 ± 3.73 years, height = 167 ± 4.32 cm, mass = 66.29 ± 10.74 kg) groups.

Intervention(s):
The training group completed a 9-week program during which participants performed 3 sessions per week of ten 15-second isometric contractions with a 30-second active rest of 3 exercises (half-squat, wide-stance squat, 1-legged half-squat) on an SAV plate (acceleration = 0.91–16.3g). The control group did not participate in any form of exercise over the 9-week period.

Main Outcome Measure(s):
We evaluated isokinetic and isometric strength of the knee extensors and flexors and ankle plantar flexors, dorsiflexors, and evertors. Static balance was assessed using 3 tasks of increasing difficulty (quiet bipedal stance, tandem stance, 1-legged stance). The electromyographic activity of the vastus lateralis, semitendinosus, medial gastrocnemius, tibialis anterior, and peroneus longus was recorded during postural task performance, baseline and pretraining, immediately posttraining, and 15 days posttraining.

Results:
After training in the training group, ankle muscle strength improved (P = .03), whereas knee muscle strength remained unaltered (P = .13). Improved ankle-evertor strength was observed at all angular velocities (P = .001). Postural sway decreased in both directions but was greater in the mediolateral (P &lt; .001) than anteroposterior (P = .02) direction. The electromyographic activity of the peroneus longus increased during the sharpened tandem (P = .001) and 1-legged tasks (P = .007). No changes were seen in the control group for any measures.

Conclusions:
The SAV training could enhance ankle muscle strength and reduce postural sway during static balance performance. The reduction in mediolateral sway could be associated with the greater use of ankle evertors due to their strength improvement.
Therapeutic Interventions for Increasing Ankle Dorsiflexion After Ankle Sprain: A Systematic Review
Authors: Terada Masafumi , Pietrosimone Brian G. , Gribble Phillip A. 
Published: August 2013

Context:
Clinicians perform therapeutic interventions, such as stretching, manual therapy, electrotherapy, ultrasound, and exercises, to increase ankle dorsiflexion. However, authors of previous studies have not determined which intervention or combination of interventions is most effective.

Objective:
To determine the magnitude of therapeutic intervention effects on and the most effective therapeutic interventions for restoring normal ankle dorsiflexion after ankle sprain.

Data Sources:
We performed a comprehensive literature search in Web of Science and EBSCO HOST from 1965 to May 29, 2011, with 19 search terms related to ankle sprain, dorsiflexion, and intervention and by cross-referencing pertinent articles.

Study Selection:
Eligible studies had to be written in English and include the means and standard deviations of both pretreatment and posttreatment in patients with acute, subacute, or chronic ankle sprains. Outcomes of interest included various joint mobilizations, stretching, local vibration, hyperbaric oxygen therapy, electrical stimulation, and mental-relaxation interventions.

Data Extraction:
We extracted data on dorsiflexion improvements among various therapeutic applications by calculating Cohen d effect sizes with associated 95% confidence intervals (CIs) and evaluated the methodologic quality using the Physiotherapy Evidence Database (PEDro) scale.

Data Synthesis:
In total, 9 studies (PEDro score = 5.22 ± 1.92) met the inclusion criteria. Static-stretching interventions with a home exercise program had the strongest effects on increasing dorsiflexion in patients 2 weeks after acute ankle sprains (Cohen d = 1.06; 95% CI = 0.12, 2.42). The range of effect sizes for movement with mobilization on ankle dorsiflexion among individuals with recurrent ankle sprains was small (Cohen d range = 0.14 to 0.39).

Conclusions:
Static-stretching intervention as a part of standardized care yielded the strongest effects on dorsiflexion after acute ankle sprains. The existing evidence suggests that clinicians need to consider what may be the limiting factor of ankle dorsiflexion to select the most appropriate treatments and interventions. Investigators should examine the relationship between improvements in dorsiflexion and patient progress using measures of patient self-reported functional outcome after therapeutic interventions to determine the most appropriate forms of therapeutic interventions to address ankle-dorsiflexion limitation.

AbstractInterstitial 2q deletions are very rare chromosome abnormalities. The 2q32q33 deletion was proposed as a distinct entity with characteristic phenotype. Most patients have feeding problems, growth restriction, moderate to severe developmental delay, speech delay or lack of speech, high, prominent forehead, thin sparse hair, teeth abnormalities and a high or cleft palate. We report on another rare case of interstitial 2q33 deletion found during routine karyotyping and further characterized by the use of a genomic SNP array. The patient presented here has a “Marfanoid” phenotype, hypothyroidism, and a marked tactile hypersensitivity. We concluded that hypothyroidism might be caused by the deletion of the CD28 and/or CTLA4 genes; also cardiological monitoring of patients with the deletion including BMPR2 may be considered in order to prevent the possible medical complications associated with pulmonary hypertension. © 2013 Wiley Periodicals, Inc.
Verbal memory functioning in adolescents and young adults with costello syndrome: Evidence for relative preservation in recognition memory

Published: August 2013

ABSTRACTCostello syndrome (CS) is a rare genetic disorder caused by germline mutations in the HRAS proto‐oncogene which belongs to the family of syndromes called rasopathies. HRAS plays a key role in synaptic long‐term potentiation (LTP) and memory formation. Prior research has found impaired recall memory in CS despite enhancement in LTP that would predict memory preservation. Based on findings in other rasopathies, we hypothesized that the memory deficit in CS would be specific to recall, and that recognition memory would show relative preservation. Memory was tested using word‐list learning and story memory tasks with both recall and recognition trials, a design that allowed us to examine these processes separately. Participants were 11 adolescents and young adults with molecularly confirmed CS, all of whom fell in the mild to moderate range of intellectual disability. Results indicated a clear dissociation between verbal recall, which was impaired (M = 69 ± 14), and recognition memory, which was relatively intact (M = 86 ± 14). Story recognition was highly correlated with listening comprehension (r = 0.986), which also fell in the low‐average range (M = 80 ± 12.9). Performance on other measures of linguistic ability and academic skills was impaired. The findings suggest relatively preserved recognition memory that also provides some support for verbal comprehension. This is the first report of relatively normal performance in a cognitive domain in CS. Further research is needed to better understand the mechanisms by which altered RAS‐MAPK signaling affects neuronal plasticity and memory processes in the brain. © 2013 Wiley Periodicals, Inc.

ABSTRACTThe NR5A1 gene encodes for steroidogenic factor 1, a nuclear receptor that regulates proper adrenal and gonadal development and function. Mutations identified by NR5A1 sequencing have been associated with disorders of sex development (DSD), ranging from sex reversal to severe hypospadias in 46,XY patients and premature ovarian failure (POF) in 46,XX patients. Previous reports have identified four families with a history of both 46,XY DSD and 46,XX POF carrying segregating NR5A1 sequence mutations. Recently, three 46,XY DSD sporadic cases with NR5A1 microdeletions have been reported. Here, we identify the first NR5A1 microdeletion transmitted in a pedigree with both 46,XY DSD and 46,XX POF. A 46,XY individual with DSD due to gonadal dysgenesis was born to a young mother who developed POF. Array CGH analysis revealed a maternally inherited 0.23 Mb microdeletion of chromosome 9q33.3, including the NR5A1 gene. Based on this finding, we screened patients with unexplained 46,XY DSD (n = 11), proximal hypospadias (n = 21) and 46,XX POF (n = 36) for possible NR5A1 copy‐number variations (CNVs) via multiplex ligation‐dependent probe amplification (MLPA), but did not identify any additional CNVs involving NR5A1. These data suggest that NR5A1 CNVs are an infrequent cause of these disorders but that array CGH and MLPA are useful genomic screening tools to uncover the genetic basis of such unexplained cases. This case is the first report of a familial NR5A1 CNV transmitting in a pedigree, causing both the male and female phenotypes associated with NR5A1 mutations, and the first report of a NR5A1 CNV associated with POF. © 2013 Wiley Periodicals, Inc.

Published: August 2013

ABSTRACTDeficiency of carbohydrate sulfotransferase 3 (CHST3; also known as chondroitin‐6‐sulfotranferase) has been associated with a phenotype of severe chondrodysplasia and progressive spinal involvement. Recent reports indicate that affected individuals initially present with neonatal multiple joint dislocations. We describe a 14‐year‐old Somali patient and her 3‐year‐old maternal half‐brother with novel homozygous CHST3 mutations. The proband presented at the age 5½ years with short stature and genua valga. Her clinical course was characterized by rapid progression of spinal deformities and large joint contractures. Her half‐brother presented at birth with bilateral knee dislocation and talipes equinovarus. This report of a Somali family with CHST3‐related chondrodysplasia illustrates the intrafamilial variability in phenotypic expression of this rare disorder. © 2013 Wiley Periodicals, Inc.
