Bioactive supramolecular peptide nanofibers for regenerative medicine

Cataloged from PDF version of article.Recent advances in understanding of cell-matrix interactions and the role of the extracellular matrix (ECM) in regulation of cellular behavior have created new perspectives for regenerative medicine. Supramolecular peptide nanofiber systems have been used as synthetic scaffolds in regenerative medicine applications due to their tailorable properties and ability to mimic ECM proteins. Through designed bioactive epitopes, peptide nanofiber systems provide biomolecular recognition sites that can trigger specific interactions with cell surface receptors. The present Review covers structural and biochemical properties of the self-assembled peptide nanofibers for tissue regeneration, and highlights studies that investigate the ability of ECM mimetic peptides to alter cellular behavior including cell adhesion, proliferation, and/or differentiation. © 2014 WILEY-VCH Verlag GmbH & Co.

Cerebral Venous Sinus Thrombosis With Internal Jugular Venous Thrombosis In A Male Patient With Nephrotic Syndrome

Cerebral venous sinus thrombosis with internal jugular vein thrombosis is not reported as a complication in nephrotic syndrome. We report a 40-year-old male with nephrotic syndrome, who had headache during his hospitalization. Conventional diagnostic tests showed extensive thrombosis at the proximal part of superior sagittal sinus, left cortical vein, left sigmoid-transverse sinus and left internal jugular vein. The patient underwent medical treatment and was discharged in good health after 2 weeks. The aim of this study is to report a novel case of cerebral venous sinus thrombosis with internal jugular venous thrombosis in a male patient with nephrotic syndrome.WoSScopu

Predicting nurses' organizational and professional turnover intentions

Aim Nursing shortages remain one of the most important problems in health care around the world. Existing nurses' turnover intention further exacerbates this problem. The aim of this study was to investigate the predictors of nurses' organizational and professional turnover intentions. Methods This study was conducted as a secondary analysis of existing data from the original cross-sectional study, which was conducted in three public hospitals between February, 2013 and May, 2013. Of the 1389 nurses who were working in these hospitals, 791 returned usable surveys. The data were collected by using a demographic and organizational characteristics form, an organizational and professional turnover intentions questionnaire, Organizational Commitment Scale, and Professional Commitment Scale. The data were analyzed with a stepwise logistic regression analysis. Results The common variables that predicted the organizational and professional turnover intentions were marital status, work shift, organizational affective and normative commitment, and professional affective commitment. Conclusion The relationship between the commitment and the turnover intention of the nurses was not completely consistent with the collectivist characteristics of Turkish society. The findings showed that the organizational affective and normative commitment and professional affective commitment play a significant role in influencing nurses' organizational and professional turnover intentions. It is important for organizations to recognize the significance of these variables, not only to retain their nursing workforce but also to attract new nurses

Analysis of Denver Neurodevelopmental Screening Test Results of Myelomeningocele, Hydrocephalus, and Microcephaly Patients

WOS: 000433244300005PubMed ID: 29899768Context: Spina bifida, hydrocephalus, and similar congenital central nervous system (CNS) anomalies take origin from embryologic stages weeks before birth, but assessment and follow-up of these patients are important to figure and predict the effects of these anomalies on child's neurodevelopment. Aims: To evaluate of multiple groups of congenital CNS anomalies in the neurodevelopment level. Settings and Design: The study was conducted at a research and treatment center for spina bifida patients. Materials and Methods: The study group included 348 patients with a mean age of 15.4 (+/- 15.1) months, who had spina bifida aperta, hydrocephalus, and microcephaly. Patients with other known intracranial conditions were excluded. The subjects were evaluated into five groups: Group 1, 88 patients with congenital hydrocephalus; Group 2, 48 patients with congenital hydrocephalus and ventriculoperitoneal shunt; Group 3, 148 patients with microcephaly; Group 4, 30 patients who were operated for spina bifida aperta; and Group 5, 39 patients who were operated for spina bifida aperta and also had ventriculoperitoneal shunt implantation. Denver Developmental Screening Test II was used to assess patients' neurodevelopment levels. Statistical Analysis Used: Pearson's chi-square and Fisher's exact tests were used for data analysis. Group comparisons were also made in pairs with chi-square test according to Bonferroni corrections. Frequency of abnormal findings was significantly correlated with age (P = 0.014). Results: Total score differences of five groups appeared to be statistically significant according to Pearson's chi-square test (P = 0.000). When we compared groups in pairs, abnormal results were significantly frequent in shunted groups (P < 0.01). Conclusions: Our results suggested that shunt-dependent hydrocephalus caused serious neurodevelopmental impairments in patients

CLINICAL EVALUATION OF CHILDRENS WITH SUBACUTE SCLEROSING PANENCEPHALITIS

Objective: The purpose of this study was to investigate retrospectively the clinical, electrophysiological and neuro radiological features of patients with subacute sclerosing panencephalitis (SSPE)

The Frequency of Lysosomal Acid Lipase Deficiency in Children With Unexplained Liver Disease

Objectives: Evidence suggests that lysosomal acid lipase deficiency (LAL-D) is often underdiagnosed because symptoms may be nonspecific. We aimed to investigate the prevalence of LAL-D in children with unexplained liver disease and to identify demographic and clinical features with a prospective, multicenter, cross-sectional study

Picturing asthma in Turkey: results from the Turkish adult asthma registry

Introduction: National data on asthma characteristics and the factors associated with uncontrolled asthma seem to be necessary for every country. For this purpose, we developed the Turkish Adult Asthma Registry for patients with asthma aiming to take a snapshot of our patients, thereby assigning the unmet needs and niche areas of intervention. Methods: Case entries were performed between March 2018 and March 2022. A web-based application was used to record data. Study outcomes were demographic features, disease characteristics, asthma control levels, and phenotypes. Results: The registry included 2053 patients from 36 study centers in Turkey. Female subjects dominated the group (n = 1535, 74.8%). The majority of the patients had allergic (n = 1158, 65.3%) and eosinophilic (n = 1174, 57.2%) asthma. Six hundred nineteen (32.2%) of the patients had obese asthma. Severe asthma existed in 670 (32.6%) patients. Majority of cases were on step 3–5 treatment (n: 1525; 88.1%). Uncontrolled asthma was associated with low educational level, severe asthma attacks in the last year, low FEV1, existence of chronic rhinosinusitis and living in particular regions. Conclusion: The picture of this registry showed a dominancy of middle-aged obese women with moderate-to-severe asthma. We also determined particular strategic targets such as low educational level, severe asthma attacks, low FEV1, and chronic rhinosinusitis to decrease uncontrolled asthma in our country. Moreover, some regional strategies may also be needed as uncontrolled asthma is higher in certain regions. We believe that these data will guide authorities to reestablish national asthma programs to improve asthma service delivery
