Iliopsoas Cyst Causing Persistent Pain After Total Hip Arthroplasty
Authors: Wuenschel Markus , Kunze Beate
Published: May 2011

Persistent pain after total hip arthroplasty (THA) has many potential causes. The most common are aseptic loosening, infection, and heterotopic ossification. Irritation of the iliopsoas tendon due to the acetabular component is an underestimated cause of persistent groin pain and functional disability after THA with rare incidence. Pain specific to iliopsoas tendonitis includes activities such as hyperextension of the hip, forced flexion, and activities of daily living (eg, ascending stairs). This article presents a case of a 50-year old man with clinical and radiological signs of osteoarthritis of the right hip joint. A THA was performed. After a symptom-free interval of several weeks postoperatively, the patient reported pain projecting from the right groin and radiating ventromedially along the leg. Magnetic resonance imaging of the hip showed a fluid-filled cyst in anatomical proximity to the femoral nerve causing an iliopsoas tendonitis. The patient underwent surgical resection of the cyst was performed by an anterior approach; a conjunction to the hip joint was not present. The implanted components of the prosthesis showed good osseointegration with no signs of loosening. The cyst was removed and the iliopsoas tendon was released. A few weeks after the operation, the patient was pain free. At 17-month follow-up, no problems were reported. In cases such as this, finding the correct diagnosis may be difficult and misleading. Conservative and operative therapeutic options are discussed and compared with divergent findings in the literature.
Lower Extremity Bypass Graft Occlusion After Intramedullary Fixation of Intertrochanteric Hip Fracture on a Fracture Table
Authors: Wiltfong Roger E. , Taylor Benjamin C. , Steensen Robert N.
Published: May 2011

This article presents a case of a 90-year-old woman who previously underwent a common femoral to anterior tibial artery bypass grafting with a Gore-Tex graft (Gore Medical, Flagstaff, Arizona). She subsequently sustained an ipsilateral intertrochanteric hip fracture after a mechanical fall and underwent internal fixation with an intramedullary nail using a fracture table. In the immediate postoperative period, she developed limb-threatening ischemia in her leg due to graft thrombosis. The patient underwent a successful thrombectomy and embolectomy. However, she subsequently developed nonhealing ulcers to this extremity over the course of weeks, requiring surgical debridement. Gangrene ensued and she underwent a below-the-knee amputation.

Complications from the use of fracture tables have been described for perineal soft tissue injury, leg malrotation or malalignment, neurologic injury, and iatrogenic compartment syndrome of the healthy leg. Arterial complications after intramedullary fixation of femur fractures are rare and may be caused by direct arterial trauma during placement of the locking screws through the intramedullary nail. This article is the first, to our knowledge, to describe an occlusion of a lower extremity bypass graft after intramedullary fixation on a fracture table. Surgeons should be aware of potential limb threatening ischemia in patients with peripheral vascular disease, especially in those with prior lower extremity bypass grafts. Proper preoperative counseling should be given to these patients when using fracture tables during hip fracture surgery.
Characteristics of Unsafe Undergraduate Nursing Students in Clinical Practice: An Integrative Literature Review
Authors: Killam Laura A. , Luhanga Florence , Bakker Debra
Published: May 2011

Providing quality clinical experiences for nursing students is vital to the development of safe and competent professional nurses. However, clinical educators often have difficulty identifying and coping with students whose performance is unsatisfactory. The purposes of this integrative review were to examine the extent and quality of the literature focusing on unsafe nursing students in clinical settings and to describe the characteristics of nursing students considered unsafe in clinical settings. A structured literature search yielded 11 relevant articles: five theoretical articles and six research studies. Analysis of findings revealed three themes: ineffective interpersonal interactions, knowledge and skill incompetence, and unprofessional image. The themes reflected the attitudes, actions, and behaviors that influenced students’ ability to develop a safe milieu for client care. The findings provide clarity for early identification of students in need of increased support and facilitate clinical educators in meeting students’ learning needs to ensure patient safety.
Update on International Adoption: Focus on Russia
Authors: McGuinness Teena M. , Robinson Cheryl Broadus
Published: May 2011

American families will continue to adopt children from foreign countries; the desire to have a child transcends national boundaries. Sadly, not all adoptions have happy outcomes. A recent and well-reported incident involved an American mother, who, exasperated with her adopted son’s severe behavioral problems, returned him to Russia, alone, on an aircraft. Other tragic reports involve internationally adopted children who have died at the hands of their American parents. This article provides an overview of the consequences of institutionalization as a risk factor for behavioral health of children; implications for nursing care of adoptive families follow.
Methodological Issues in Fall Prevention Research Involving Older Adults in Long-Term Care Facilities
Authors: Kehinde Julius Oluwole , Pope Charlene , Amella Elaine J.
Published: May 2011

The purpose of this study was to conduct a systematic review of the current fall prevention literature, examining methodological issues resulting from variations in fall definitions, methods of data collection, and standards for reporting fall rates in studies involving older adults in long-term care settings. This systematic review used the five stages of Whittemore and Knafl’s review methodology to extract data from the databases, summarize, and synthesize the findings of the 10 studies included. The Critical Appraisal Skill Program checklist for randomized controlled trials criteria was used to appraise the methodological quality of the studies. Inconsistencies in fall definitions, methods of data collection, and standards for reporting fall rates were apparent across the studies reviewed. Standardized approaches to defining falls, collecting data, and reporting fall rates are necessary to interpret, make comparisons among, and disseminate the findings of studies.

This article presents a novel approach for distance management for e-learning platforms based on VeSMp protocol. VeSMEL results from the integration of VeSMp to xMoodle 2.0 platform that has been developed. It offers a compromise between the mobility of actors and the availability of xMoodle 2.0 content in zones where internet is inaccessible. The GSM system is used like support for communication allowing the actors to reach servers from their cell phone.
End of Life: A Family Narrative
Authors: Black Helen K. , Moss Miriam S. , Rubinstein Robert L. , Moss Sidney Z.
Published: May 2011

This paper is based on ethnographic research that examines family reaction to an elderly husband and father's end of life. From a group of 30 families in our study (family defined as a widow aged 70 and over and two adult biological children between the ages of 40 and 60), we offer an extreme case example of family bereavement. We report our findings through the open-ended responses of a widow and two children who were interviewed ten months after the death of the husband and father. Three general themes emerged: (1) how the family imputes meaning to the end of life, (2) changes in the roles of family members, and (3) the family's ways of coping with the death, particularly through their belief system. A key finding is that the meaning family members find in their loved one's death is tied to the context of his death (how and where he died), their perception of his quality of life as a whole, and their philosophical, religious, and spiritual beliefs about life, death, and the afterlife that are already in place.
Differential Gene Expression in Primary Breast Tumors Associated with Lymph Node Metastasis

Published: May 2011

Lymph node status remains one of the most useful prognostic indicators in breast cancer; however, current methods to assess nodal status disrupt the lymphatic system and may lead to secondary complications. Identification of molecular signatures discriminating lymph node-positive from lymph node-negative primary tumors would allow for stratification of patients requiring surgical assesment of lymph nodes. Primary breast tumors from women with negative () and positive () lymph node status matched for possible confounding factors were subjected to laser microdissection and gene expression data generated. Although ANOVA analysis (, fold-change >1.5) revealed 13 differentially expressed genes, hierarchical clustering classified 90% of node-negative but only 66% of node-positive tumors correctly. The inability to derive molecular profiles of metastasis in primary tumors may reflect tumor heterogeneity, paucity of cells within the primary tumor with metastatic potential, influence of the microenvironment, or inherited host susceptibility to metastasis.
Eicosanoid Production following One Bout of Exercise in Middle-Aged African American Pre- and Stage 1 Hypertensives
Authors: Williamson Sheara , Varma Deepti , Brown Michael , Jansen Susan
Published: May 2011

Endothelial dysfunction and a sedentary lifestyle may be involved in the development of hypertension which is proliferative among middle-aged African Americans (AA). Signaling molecules derived from the oxidation of 20-carbon fatty acid molecules known as eicosanoids influence vascular tone. The relationship between aerobic fitness and eicosanoid formation following exercise in middle-aged African American hypertensives is unknown.Purpose. To determine the relationship between aerobic capacity and eicosanoid formation after a bout of moderate-intensity exercise in middle-aged AA hypertensives.Methods. Ten sedentary hypertensive AA underwent 50 min of aerobic exercise at 65% VO2max. Urine was collected for 24 hr on two occasions, prior to testing and immediately following the bout of exercise. Urinary metabolites of prostacyclin (6-keto PGF1α) and thromboxane (11-dTXB2) were measured during the day and night periods by high-performance liquid chromatography (HPLC).Results. 6-keto PGF1αlevels significantly increased () following the bout of exercise compared to the control day. There was a significant relationship (, ) between 6-keto PGF1αlevels and VO2max during the exercise day.Conclusion. Based on this preliminary study, there appears to be a relationship between aerobic capacity and exercise-induced 6-keto PGF1αproduction in middle-aged hypertensive AAs. AAs with lower VO2max had lower 6-keto PGF1αformation.
Prosthetic Aortic Valve Stenosis in End-Stage Renal Failure
Authors: Mao Michael , El Ters Mirelle , Mankad Sunil , Keddis Mira , Park Soon , Qian Qi
Published: May 2011

Although renal failure is one of the known comorbidities associated with rapid progression of aortic stenosis, it is unclear whether hemodialysis alters the progression of prosthetic aortic valve stenosis. We describe a 79-year-old female who underwent bioprosthetic aortic valve replacement 8 years ago with stable prosthetic valve area for the initial 6 years. In the last two years, coinciding with the initiation of maintenance hemodialysis, she developed progressive prosthetic valve stenosis to the point of clinical decompensation. She underwent a second prosthetic aortic valve replacement with symptom resolution. This case suggests that circulating milieu in end-stage renal failure and dialysis can accelerate the progression of prosthetic aortic valve stenosis. More frequent clinical followup and surveillance echocardiogram for dialysis patients with bioprosthetic aortic valve may facilitate timely management of valvular stenosis.
Internal Mammary Arterial Injury from Lead Extraction: A Clinically Subtle yet Important Complication of Implantable Device Removal
Authors: Cruz Cesar , Langberg Jonathan , Lerakis Stamatios , Veeraswamy Ravi , Lloyd Michael
Published: May 2011

Percutaneous implantable device extraction has increased in recent years and is associated with small but significant risk. Arteriovenous fistula formation is an uncommon complication of this procedure. We report two cases where lead extraction was complicated by an arteriovenous fistula between the left internal mammary artery and the left brachiocephalic vein. In both cases, the patients were asymptomatic and the presence of a continuous murmur in the left subclavicular region led to the appropriate diagnosis. These were successfully treated with coil embolization. Auscultation around prior extraction sites should be routinely done to aid in the diagnosis of this potentially harmful complication.
Vitamin D Receptor Activators and Clinical Outcomes in Chronic Kidney Disease
Authors: Gravellone Luciana , Rizzo Maria Antonietta , Martina Valentina , Mezzina Nicoletta , Regalia Anna , Gallieni Maurizio
Published: May 2011

Vitamin D deficiency appears to be an underestimated risk factor for cardiovascular disease in patients with chronic kidney disease. Evidence from both basic science and clinical studies supports the possible protective role of vitamin D beyond its effect on mineral metabolism. Toxicity of pharmacologic doses of active vitamin D metabolites, in particular calcitriol, is mainly due to the possibility of positive calcium and phosphorus balance. Therefore, vitamin D analogs have been developed, which suppress PTH secretion and synthesis with reduced calcemic and phosphatemic effects. Observational studies suggest that in hemodialysis patients the use of a vitamin D receptor (VDR) activator, such as calcitriol, doxercalciferol, paricalcitol, or alfacalcidol, is associated with a reduced mortality when compared with nonusers of any VDR activator. In this article the existing literature on the topic is reviewed, although a more robust answer to the question of whether or not VDR activators have beneficial effects in hemodialysis patients will hopefully come from a randomized controlled trial.
Estimating Premorbid Intelligence among Older Adults: The Utility of the AMNART
Authors: Lowe Deborah A. , Rogers Steven A.
Published: May 2011

This study examines the utility of the American version of the National Adult Reading Test (AMNART) as a measure of premorbid intelligence for older adults. In a sample of 130 older adults, aged 56 to 104, the AMNART was compared to other tests of premorbid intelligence. The results revealed that AMNART-estimated IQ was significantly higher than other premorbid estimates. Across specific educational groups (i.e., 0–12, 13–16, and 17 or more years of education), AMNART-estimated IQ was inflated relative to all other premorbid estimates. The AMNART also declined as cognitive impairment increased, and there was a significant interaction between aging-related diagnostic group and premorbid estimate. The AMNART may therefore overestimate premorbid ability relative to other premorbid measures, particularly among those with greater cognitive impairment and lower levels of education. These results suggest that the AMNART should be used cautiously among older adults and in conjunction with other estimates of premorbid ability.

Published: May 2011

We conducted a prospective, randomized study to compare conventional continuous venovenous hemodiafiltration (CVVHDF) with sustained hemodiafiltration (SHDF) using an acetate-free dialysate. Fifty critically ill patients with acute kidney injury (AKI) who required renal replacement therapy were treated with either CVVHDF or SHDF. CVVDHF was performed using a conventional dialysate with an effluent rate of 25 mL⋅kg−1⋅h−1, and SHDF was performed using an acetate-free dialysate with a flow rate of 300−500 mL/min. The primary study outcome, 30 d survival rate was 76.0% in the CVVHDF arm and 88.0% in the SHDF arm (NS). Both the number of patients who showed renal recovery (40.0% and 68.0%, CVVHDF and SHDF, resp.;P<.05), and the hospital stay length (42.3 days and 33.7 days, CVVHDF and SHDF, resp.;P<.05), significantly differed between the two treatments. Although the total convective volumes did not significantly differ, the dialysate flow rate was higher and mean duration of daily treatment was shorter in the SHDF treatment arm. Our results suggest that compared with conventional CVVHDF, more intensive renal support in the form of post-dilution SHDF with acetate-free dialysate may accelerate renal recovery in critically ill patients with AKI.

Published: May 2011

Impairment of olfaction is a characteristic and early feature of Parkinson's disease. Recent data indicate that >95% of patients with Parkinson's disease present with significant olfactory loss. Deficits in the sense of smell may precede clinical motor symptoms by years and can be used to assess the risk for developing Parkinson's disease in otherwise asymptomatic individuals. This paper summarizes the available information about olfactory function in Parkinson's disease, indicating the advantageous use of olfactory probes in early and differential diagnosis.
Nephronophthisis: A Genetically Diverse Ciliopathy
Authors: Simms Roslyn J. , Hynes Ann Marie , Eley Lorraine , Sayer John A.
Published: May 2011

Nephronophthisis (NPHP) is an autosomal recessive cystic kidney disease and a leading genetic cause of established renal failure (ERF) in children and young adults. Early presenting symptoms in children with NPHP include polyuria, nocturia, or secondary enuresis, pointing to a urinary concentrating defect. Renal ultrasound typically shows normal kidney size with increased echogenicity and corticomedullary cysts. Importantly, NPHP is associated with extra renal manifestations in 10–15% of patients. The most frequent extrarenal association is retinal degeneration, leading to blindness. Increasingly, molecular genetic testing is being utilised to diagnose NPHP and avoid the need for a renal biopsy. In this paper, we discuss the latest understanding in the molecular and cellular pathogenesis of NPHP. We suggest an appropriate clinical management plan and screening programme for individuals with NPHP and their families.
Impact of Pentoxifylline and Vitamin E on Ribavirin-Induced Haemolytic Anaemia in Chronic Hepatitis C Patients: An Egyptian Survey
Authors: Assem M. , Yousri M.
Published: May 2011

Background/Aim. We evaluate the impact of combined pentoxifylline and high-dose vitamins E to standard antiviral treatment on RBV-induced haemolytic anaemia.Patients and Methods. Selected 200 naïve chronic HCV patients, were randomized to receive either the standard antiviral therapy (peginterferon α-2b and RBV) plus pentoxifylline (800 mg) and high-dose vitamin E (1000 iu) daily (combined group) or received standard antiviral therapy plus placebo only (control group). They were followed up during treatment course and for 6 months posttreatment to assess the occurrence of anaemia and virological response, respectively.Results. RBV dose modification due to anaemia were significantly less in combined group (8.5 versus 21.5%.P<.05).Withdrawal, secondary to sever anemia (Hb<8.5 gm%), was recorded only in 6 (28.6%) patients of the control group. Both (ETR) and (SVR) were significantly higher in combined group than control group by both intention-to-treat analysis (71 versus 56%,P<.05and 66 versus 49%,P<.05) and per-protocol analysis (85.5 versus 70.9%,P<.05and 79.5 versus 62%,P<.05).Conclusion. Pentoxifylline and vitamin E can ameliorate RBV-associated haemolysis; improve compliance and virologic clearance when combined with the standard antiviral therapy in patients with chronic hepatitis C.
The Use of Auditory Event‐Related Potentials in Alzheimer′s Disease Diagnosis
Authors: Vecchio Fabrizio , Määttä Sara
Published: May 2011

Event‐related potentials (ERPs) are important clinical and research instruments in neuropsychiatry, particularly due to their strategic role for the investigation of brain function. These techniques are often underutilized in the evaluation of neurological and psychiatric disorders, but ERPs are noninvasive instruments that directly reflect cortical neuronal activity. Previous studies using the P300, P3a, and MMN components of the ERP to study dementing illness are reviewed. The results suggest that particularly the P300 brain potential is sensitive to Alzheimer′s disease processes during its early stages, and that easily performed stimulus discrimination tasks are the clinically most useful. Finally, these data suggest that the P300 ERP can aid in the diagnosis of dementia and may help in the assessment of early Alzheimer′s disease.
Combining Transcranial Magnetic Stimulation and Electroencephalography May Contribute to Assess the Severity of Alzheimer′s Disease

Published: May 2011

Alzheimer′s disease (AD) is the most common form of old age dementia, and mild cognitive impairment (MCI) often precedes AD. In our previous study (Julkunen et al. 2008), we found that the combination of transcranial magnetic stimulation (TMS) and electroencephalography (EEG) was able to find distinct differences in AD and MCI patients as compared to controls. Here, we reanalyzed the small sample data from our previous study with the aim to test the sensitivity of the TMS‐EEG characteristics to discriminate control subjects (n = 4) from MCI (n = 5) and AD (n = 5) subjects. Furthermore, we investigated how the TMS‐EEG response characteristics related to the scores of the dementia rating scales used to evaluate the severity of cognitive decline in these subjects. We found that the TMS‐EEG response P30 amplitude correlated with cognitive decline and showed good specificity and sensitivity in identifying healthy subjects from those with MCI or AD. Given the small sample size, further studies may be needed to confirm the results.
Aggressive Palliation in Extensive Stage Small Cell Lung Cancer, Practice Guidelines versus Clinical Practice: A Case Report and Review of the Literature
Authors: Miles Edward F. , Jacimore Laura L. , Nelson John W.
Published: May 2011

Small cell lung cancer (SCLC) constitutes approximately 16% of all primary lung cancers, with more than 35,000 new cases per year. Two-thirds of patients present with extensive stage disease (ES-SCLC) due to a tendency to metastasize early. Outcomes remain poor, with a median survival of approximately 10 months and a two-year overall survival of <10%. Current recommendations call for combination chemotherapy alone in patients without localized symptoms. Thoracic radiation therapy following a good clinical response is controversial. We report on a patient with ES-SCLC that had an excellent response to chemotherapy and underwent whole brain radiotherapy for a known brain metastasis and consolidative radiotherapy to the thorax. His latest follow-up demonstrates only a stable residual pulmonary nodule and no evidence of active metastatic disease. ES-SCLC is a relatively common presentation with a variable burden of metastatic disease. In the absence of randomized trials demonstrating the efficacy of thoracic radiation therapy, the community radiation oncologist is placed in a difficult position when addressing these patients, particularly those with otherwise good performance status and a good response to initial systemic chemotherapy. More research in this area is sorely needed to help guide treatment recommendations.
HEALS: A Faith-Based Hypertension Control and Prevention Program for African American Churches: Training of Church Leaders as Program Interventionists
Authors: Dodani Sunita , Sullivan Debra , Pankey Sydney , Champagne Catherine
Published: May 2011

Background. A 12-session church-based HEALS program (healthy eating and living spiritually) was developed for hypertension control and prevention program in African Americans (AAs). This study presents specifics of training lay health educators to effectively deliver HEALS to high-risk AAs.Methods. A one-day workshop was conducted by the research experts in an AA church. Five church members were recruited to be program interventionists called church health counselors (CHCs).Results. Using principles of adult education, a training protocol was developed with the intention of recognizing and supporting CHCs skills. CHCs received training on delivering HEALS program. The process of training emphasized action methods including role playing and hands-on experience with diet portion measurements.Conclusion. With adequate training, the community lay health educator can be an essential partner in a community-based hypertension control programs. This may motivate program participants more and encourages the individual to make the behavior modifications on a permanent basis.
Add-on-Statin Extended Release Nicotinic Acid/Laropiprant but Not the Switch to High-Dose Rosuvastatin Lowers Blood Pressure: An Open-Label Randomized Study
Authors: Kei Anastazia , Elisaf Moses , Moutzouri Elisavet , Tsiara Stavroula , Liberopoulos Evangelos
Published: May 2011

Introduction. Nicotinic acid (NA) and statins have been associated with reductions in blood pressure (BP).Patients and Methods. We recruited 68 normotensive and hypertensive dyslipidemic patients who were treated with a conventional statin dose and had not achieved lipid targets. Patients were randomized to switch to high-dose rosuvastatin (40 mg/day) or to add-on current statin treatment with extended release (ER) NA/laropiprant (1000/20 mg/day for the first 4 weeks followed by 2000/40 mg/day for the next 8 weeks) for 3 months.Results. Switching to rosuvastatin 40 mg/day was not associated with significant BP alterations. In contrast, the addition of ER-NA/laropiprant to current statin treatment resulted in a 7% reduction of systolic BP (from to  mmHg, versus baseline and versus rosuvastatin group) and a 5% reduction of diastolic BP (from to  mmHg, versus baseline and versus rosuvastatin group). These reductions were significant only in the subgroup of hypertensives and were independent of the hypolipidemic effects of ER-NA/laropiprant.Conclusions. Contrary to the switch to high-dose rosuvastatin, the addition of ER-NA/laropiprant to statin treatment was associated with significant reductions in both systolic and diastolic BP.
Low Genetic and Morphometric Intraspecific Divergence in PeripheralCopadichromisPopulations (Perciformes: Cichlidae) in the Lake Malawi Basin
Authors: Anseeuw Dieter , Raeymaekers Joost A. M. , Busselen Paul , Verheyen Erik , Snoeks Jos
Published: May 2011

Peripheral isolated populations may undergo rapid divergence from the main population due to various factors such as a bottleneck or a founder effect followed by genetic drift or local selection pressures. Recent populations of two economically importantCopadichromisspecies in Lake Malombe, a satellite lake of Lake Malawi, were neither genetically nor morphometrically distinct from their source populations in the main lake. Evidence was found for a founder effect which had a different impact on the genetic composition of the two species. In addition, the increased fishing pressure in Lake Malombe may have led to a reduction of the body sizes of both species.
Federally Qualified Health Centers Minimize the Impact of Loss of Frequency and Independence of Movement in Older Adult Patients through Access to Transportation Services
Authors: Knight Krystal Elaine
Published: May 2011

Loss of mobility in older adults (65 and older) is associated with falling, loss of independence, and mortality. This paper, which to the author's knowledge is the first of its kind, summarizes findings of Federally Qualified Health Center (FQHC) case reports and how FQHCs minimize the impacts of mobility loss in older adult patients (who would not receive primary services without these transportation programs) by providing access to primary care services through transportation programs. This paper features the transportation programs of four FQHCs located in both urban and rural United States areas: LifeLong Medical Care (Oakland, CA); Hudson Headwaters Health Network (Queensbury, NY); North End Community Health Center (Boston, MA); Aaron E. Henry Community Health Services Center, Inc. (Clarksdale, MS). This paper is beneficial to primary care providers and public health officials in outlining how transportation may be used to minimize the effects of mobility loss in older adult patients.
Different Effects of Mg2+ and Zn2+ on the Two Sites for Alkylammonium Compounds in Pseudomonas aeruginosa Phosphorylcholine Phosphatase
Authors: Otero Lisandro Horacio , Beassoni Paola Rita , Boetsch Cristhian , Lisa Angela Teresita , Domenech Carlos Eduardo
Published: May 2011

Pseudomonas aeruginosa phosphorylcholine phosphatase (PchP) catalyzes the hydrolysis of phosphorylcholine (Pcho), is activated by Mg2+ or Zn2+, and is inhibited by high concentrations of substrate. This study has shown that PchP contains two sites for alkylammonium compounds (AACs): one in the catalytic site near the metal ion-phosphoester pocket, and the other in an inhibitory site responsible for the binding of the alkylammonium moiety. The catalytic mechanism for the entry of Pcho in both sites and Zn2+ or Mg2+ follows a random sequential mechanism. However, Zn2+ is more effective than Mg2+ at alleviating the inhibition produced by the entry of Pcho or different AACs in the inhibitory site. We postulate that Zn2+ induces a conformational change in the active center that is communicated to the inhibitory site, producing a compact or closed structure. In contrast, Mg2+ produces a relaxed or open conformation.

Authors: Pogranichniy Roman M. , Schnur Megan E. , Raizman Eran A. , Murphy Duane A. , Negron Maria , Thacker H. Leon
Published: May 2011

Species and biotype distribution was determined in 44 bovine viral diarrhea virus- (BVDV-) positive samples submitted to the Animal Disease Diagnostic Laboratory (ADDL) in Indiana during 2006–2008. BVDV RNA was detected in the 5′-untranslated region and Nproregion using reverse transcriptase PCR followed by sequencing analysis of the PCR product. Additionally, cases were classified into one of six categories according to history and/or lesions: acute symptomatic, hemorrhagic, respiratory distress, reproductive, persistent infection (PI), and mucosal disease (MD). Of 44 BVDV-positive samples, 33 were noncytopathic (ncp), 10 were cytopathic (cp), and one presented both ncp and cp biotypes. Sequencing analysis demonstrated that all samples belonged to BVDV-1a, BVDV-1b, or BVDV-2. The most common isolate was ncp BVDV-1b, (44%) followed by ncp BVDV-2a (24%). Among the six categories, respiratory clinical signs were the most common (36%) followed by PI (25%) and MD (16%).

Published: May 2011

Objectives. To test the relation between white matter lesions (WML) location and physical performance, in aged patients.Methods. Subjects: 29 patients (17 males), aged >65 (mean age72.6±5.2), with leukoaraiosis. WML was quantified with a visual scale; Apparent Diffusion Coefficient (ADC) was measured bilaterally in frontal periventricular lesioned white matter and frontal and parieto-occipital normal appearing white matter (NAWM). Motor performance was studied using the Short Physical Performance Battery (SPPB), single leg stand time, finger tapping and grooved pegboard tests (GPT).Results. There were significant correlations between the frontal region visual scale scores and SPPB chair stands (r=-0.379;P=.039) and Grooved Pegboard (r=0.393;P=.032); frontal NAWM ADC values and SPPB standing balance (r=-0.450;P=.014) and SPPB 4 meter walk (r=-0.379;P=.043).Conclusion. Frontal WML are negatively related to motor performance in patients with leukoaraiosis. DWI results suggest that this may be true even for NAWM.

Authors: Chebolu Sunil K. , Christensen J. Daniel , Mináč Ján
Published: May 2011

Let G be a finite group, and let k be a field whose characteristic p divides the order of G. Freyd's generating hypothesis for the stable module category of G is the statement that a map between finite-dimensional kG-modules in the thick subcategory generated by k factors through a projective if the induced map on Tate cohomology is trivial. We show that if G has periodic cohomology, then the generating hypothesis holds if and only if the Sylow p-subgroup of G is C2 or C3. We also give some other conditions that are equivalent to the GH for groups with periodic cohomology.

Various weighted lp-norm inequalities in convolutions are derived by a simple and general principle whose l2 version was obtained by using the theory of reproducing kernels. Applications to the Riemann zeta function and a difference equation are also considered.
Retratos secretos. Figuraciones de la identidad en el espacio virtual
Authors: Tabachnik Silvia
Published: May 2011

Inéditas experiencias del cuerpo, los lenguajes, el espacio y el tiempo, conducen a reformular, más allá de la lógica de la identidad, las preguntas sobre las operaciones que intervienen en los procesos de constitución y de transformación de la subjetividad en el nuevo dominio de lo virtual. En tanto garantiza ciertas condiciones de anonimato, el régimen virtual favorece la suspensión de la identidad establecida para la "vida civil" y propicia diversos procesos semióticos de refiguración identitaria,Dichos procesos son abordados en este trabajo mediante una aproximación analítica a los procedimientos de "presentación de sí" que regulan el ingreso de los sujetos a las comunidades virtuales.
Los hábitos y preferencias televisivas en jóvenes y adolescentes: Un estudio realizado en el País Vasco
Authors: Medrano Samaniego Concepción , Palacios-Navarro Santiago , Aierbe Barandiaran Ana
Published: May 2011

En este trabajo se ha tratado de conocer qué y cuánto ven la televisión en una muestra de 144 jóvenes y adolescentes de la Comunidad Autónoma del País Vasco. El objetivo general ha sido conocer nuestra realidad y contrastarla con los datos disponibles de otras investigaciones. Se presenta una revisión de otros trabajos sobre este mismo tema y a continuación se exponen los resultados obtenidos tras aplicar el Cuestionario de Hábitos Televisivos (CH-TV) creado “ad hoc” para esta investigación. Los datos hallados nos indican que el tiempo dedicado a ver la T.V. no es tan alto como en ocasiones se presupone, ni tampoco desplaza a otras actividades. En cuanto a la dieta televisiva los contenidos preferidos son las series de ficción y los informativos, no siendo los programas más perniciosos los más vistos.
Internet governance y sociedad de la información: problemas de socio-política
Authors: Adinolf Giulio
Published: May 2011

La sociedad de la información refleja un efecto de la creciente expansión de la globalización que determina un aumento general en la velocidad de todo el sistema. El Internetwork World Wide Web representa la síntesis o el núcleo de la sociedad globalizada. La ONU y la Cumbre Mundial de la Sociedad de la Información han otorgado poderes a un organismo el Work Group of Internet Governance el cual tiene el deber de que se elabore una posible gobernanza de “Internet”. Este grupo tiene que enfrentarse a problemas políticos como la gobernabilidad en lo referente a la manifestación estatal del poder público y de gobernanza en lo que afecta a la completa participación de la sociedad.
Cultura y televisión. Concepto y presencia de los canales culturales en Europa Occidental
Authors: Llorens Maluquer Carles , Aymerich Franch Laura
Published: May 2011

A partir de las distintas definiciones de cultura –popular y elitista–, se analiza la realidad del canal cultural en las principales plataformas digitales y en la oferta de canales en abierto públicos y privados de los cinco países europeos con los mercados de televisión más importantes: Alemania, Reino Unido, Francia, Italia y España. Los cincuenta canales hallados se agrupan por temáticas, según la extensión del contenido (generalista o temático) y la titularidad (pública o privada). De estas clasificaciones se desprende que los canales culturales generalistas son operados por las televisiones públicas, mientras que los operadores privados prefieren los canales culturales temáticos. Por último, exceptuando el caso de ARTE, los únicos canales culturales transeuropeos son los de matriz norteamericana como Discovery Channel o National Geographic

En torno a la investigación en relaciones públicas
Authors: Martínez Mendoza Sarelly
Published: May 2011

La investigación es una vía para mejorar continuamente las relaciones públicas (RRPP). De ahí que este ensayo apueste por retomar los procesos de investigación para consolidar la disciplina, y explicar detenidamente los tipos de investigación (básica, introspectiva y aplicada) que se emplean en RRPP. También reflexiona sobre los enfoques de investigación (seguimientos de un ambiente creado, auditorías de relaciones públicas, auditorías en comunicación, etnografías y estudios de caso), las técnicas (análisis de contenido, análisis del discurso, grupos focales y encuesta), y los instrumentos (cuestionarios, pruebas o experimentos) que deben utilizarse en esta disciplina. Se parte del principio de que la investigación, en todas sus fases, es el elemento transformador de las relaciones públicas. De que hoy no es posible poner en marcha un programa de RRPP exitoso sino se apoya continuamente en la investigación. La investigación marca la viabilidad de un programa de RRPP. La intuición, la inspiración y la improvisación, como únicos elementos de apoyo, deben quedar en el pasado, y deben ser sustituidos por la investigación científica.
Valores en alza: guerras, propaganda mediática, cultura del miedo y “hedocinismo”
Authors: Camiñas Hernández Tasio
Published: May 2011

Este artículo es una reflexión crítica basada en el estudio de los acontecimientos derivados del 11-S vistos a través del discurso de los expertos reflejado en la prensa española de referencia. En este análisis se ha observado la evidencia de un discurso propagandístico oficial que es diseminado a diario por las empresas de comunicación globales y los poderes político y económico para imponer una cultura del miedo y de guerra permanente en una sociedad sumergida en dos valores en alza: el cinismo y el hedonismo (“hedocinismo”). Los acontecimientos del 11 de septiembre de 2001 iniciaron esta nueva era de “guerra contra el terrorismo”, que ha provocado un nuevo enfrentamiento entre Oriente y Occidente, un choque de fanatismos religiosos (cristianismo radical frente a islamismo radical), y que puede desembocar en una tercera fase de la globalización basada en una nueva etapa de disuasión armamentística a escala mundial.
YouTube, el mediador de la cultura popular en el ciberespacio
Authors: Porto Renó Denis
Published: May 2011

El mundo vive cambios en los medios de comunicación de masa, tornando elles cada vez más globalizados. Por otro lado, la tecnología tiene cambiado los procesos y las limitaciones de estos procesos comunicacionales, con la simplificación de estos y quien tiene acceso a la Internet puede criar comunidades, publicar informaciones y exhibir sus videos producidos en tecnología digital. El artículo discute el YouTube como agente mediador de producciones de carácter folkcomunicacional disponibles en la Internet a través de uno estudio de caso del acervo folkmediático del mismo, tenido como suporte teórico especialmente los métodos de Luiz Beltrão y el optimismo de Néstor Canclini con relación a los efectos de la globalización.
La economía política de la investigación informacional
Authors: Almirón Roig Núria
Published: May 2011

Este trabajo presenta un análisis de los actores que impulsan actualmente las principales actividades de investigación relacionadas con la llamada sociedad de la información y la comunicación digital (denominada aquí investigación informacional). Tal análisis pone de manifiesto un estrecho vínculo de ésta investigación con unos determinados sectores económicos y empresariales, que son los que construyen hoy el discurso dominante en este ámbito. El trabajo defiende que la actual investigación informacional mantiene las mismas limitaciones de la investigación administrada estadounidense del siglo pasado, fruto de un enfoque igualmente descontextualizado e igualmente basado esencialmente en los efectos.
La crisis de los discursos radiofónicos
Authors: Garcés Raúl
Published: May 2011

Dentro de un contexto mediático marcado por la revolución de la ‘prensa’ digital y el impacto cada vez mayor de la televisión, se habla con frecuencia de la radio desde posiciones polarizadas: de un lado figuran quienes la estigmatizan como un medio perteneciente al pasado, cuya relación con las audiencias más jóvenes tiende a languidecer; de otro, quienes le auguran larga vida como gestora de experiencias de comunicación comunitaria y alternativa. El autor repasa algunos de los argumentos que sostienen ambos enfoques y alerta sobre la necesidad de despojar al discurso radiofónico actual de recursos trillados, para revestirlo con formas experimentales de realización cada vez más audaces y creativas. Asimismo, reflexiona en torno a los desafíos de la radio cubana para conquistar nuevas audiencias, dentro de un contexto donde la televisión y la prensa escrita de la Isla empiezan a recuperarse de la crisis económica que azotó Cuba tras la desaparición del campo socialista.
La música como recurso expresivo en los informativos radiofónicos. Análisis de su uso en los noticiarios de mediodía
Authors: Jiménez Martín Silvia
Published: May 2011

La música es uno de los elementos más expresivos del lenguaje radiofónico y no existen razones por las que se deba prescindir de ella en el discurso informativo. Sin embargo, los editores de los programas principales de noticias nacionales no la utilizan, restando de este modo atractivo a los noticiarios. Un análisis formal de los informativos de mediodía de más audiencia del país, en el que se contabilizan los segundos dedicados a la música diegética y extradiegética, revela que los editores construyen su discurso casi exclusivamente con palabras. La escasa armonización de elementos que presentan los noticiarios reduce sus posibilidades comunicativas. En este artículo tratamos de promover el uso de la música en los informativos, un elemento que, combinado con las palabras, ayuda a comprender mejor los densos contenidos que se ofrecen en este tipo de programas, capta la atención de la audiencia y, en un segundo nivel, despierta su interés por la información.
