Parkin absence accelerates microtubule aging in dopaminergic neurons

Loss-of-function caused by mutations in the parkin gene (PARK2) lead to early-onset familial Parkinson's disease. Recently, mechanistic studies proved the ability of parkin in regulating mitochondria homeostasis and microtubule (MT) stability. Looking at these systems during aging of PARK2 knockout mice, we found that loss of parkin induced an accelerated (over)acetylation of MT system both in dop

Serotype distribution of clinical streptococcus pneumoniae isolates before the introduction of the 13-valent pneumococcal conjugate vaccine in Cambodia

Childhood vaccination with the 13-valent pneumococcal conjugate vaccine (PCV13) was introduced in Cambodia in January 2015. Baseline data regarding circulating serotypes are scarce. All microbiology laboratories in Cambodia were contacted for identification of stored isolates of Streptococcus pneumoniae from clinical specimens taken before the introduction of PCV13. Available isolates were serotyp

Characterization of Patients with Embolic Strokes of Undetermined Source in the NAVIGATE ESUS Randomized Trial

Background: The New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial vs. ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial is a randomized phase-III trial comparing rivaroxaban versus aspirin in patients with recent ESUS. Aims: We aimed to describe the baseline characteristics of this large ESUS cohort to explore relationships among key subgroups.

Tumor-associated autoantibodies as early detection markers for ovarian cancer? A prospective evaluation

Immuno-proteomic screening has identified several tumor-associated autoantibodies (AAb) that may have diagnostic capacity for invasive epithelial ovarian cancer, with AAbs to P53 proteins and cancer-testis antigens (CTAGs) as prominent examples. However, the early detection potential of these AAbs has been insufficiently explored in prospective studies. We performed ELISA measurements of AAbs to C

Mutational spectrum in a worldwide study of 29,700 families with BRCA1 or BRCA2 mutations

The prevalence and spectrum of germline mutations in BRCA1 and BRCA2 have been reported in single populations, with the majority of reports focused on White in Europe and North America. The Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) has assembled data on 18,435 families with BRCA1 mutations and 11,351 families with BRCA2 mutations ascertained from 69 centers in 49 countries on six

Pulmonell hypertension vanligt vid vänstersidig hjärtsjukdom - Kunskapsläget är dåligt – fler kliniska studier behövs

Pulmonell hypertension är en vanlig komplikation till vänstersidig hjärtsjukdom och medför såväl försämrad livskvalitet som försämrad prognos.Den pulmonella hypertensionen beror initialt på passiv stockning av blod i lungkretsloppet men kan kompliceras av såväl pulmonell vasokonstriktion som vaskulär remodulering.2015 års europeiska riktlinjer innefattar en ny definition av pulmonell hypertension Pulmonary hypertension (PH) is a serious complication to left heart disease (LHD), affecting a majority of the patients during the course of the disease. Initially, PH-LHD is caused by passive congestion of the pulmonary vessels due to increased left atrial pressures, a condition that is currently denoted as isolated post-capillary PH (Icp-PH). In the majority of patients the increased atrial pres

Vitamin D and probiotics supplement use in young children with genetic risk for type 1 diabetes

Background/Objectives:Vitamin D and probiotics are nutrients of interest in the context of type 1 diabetes (T1D). We assessed the prevalence of and factors associated with vitamin D and probiotic supplementations among young children with genetic risk of T1D.Subjects/Methods:Use of supplements during the first 2 years of life was collected prospectively from 8674 children in The Environmental Dete

Mass Media : Introduction and Schools of Thought

After a brief discussion on the varying nomenclature applied to the field, this article discusses the two basic orientations: academic and applied. From there, the discussion takes up the sprawling character of the field, underscoring that the field can be conceptually organized in a variety of ways. The main part of the discussion consists of a presentation of four major schools of thought. These

Boredom in Meetings

For managers, meetings may be an arena “where the action is”: situations to display competence and moral character. However, others may feel less involved, and meetings may be experienced as nonsense, as meaningless and worthless. A recurring theme in various studies is complaints about meetings, particularly regarding their frequency, their emptiness, and the forced attendance, taking time from wFor managers, meetings may be an arena “where the action is”: situations to display competence and moral character.

Risk Screening, Testing, and Diagnosis : Ethical Aspects

After an initial clarification of the notion of the risk, a brief discussion of the distinction between testing and screening, and of the difficulties of defining genetic information in a precise way follows an overview of public concerns raised by genetic testing and screening. Next section reviews various types of ethical issues in this context. The challenges are not the same for all types and

A Large-Scale Multi-ancestry Genome-wide Study Accounting for Smoking Behavior Identifies Multiple Significant Loci for Blood Pressure

Genome-wide association analysis advanced understanding of blood pressure (BP), a major risk factor for vascular conditions such as coronary heart disease and stroke. Accounting for smoking behavior may help identify BP loci and extend our knowledge of its genetic architecture. We performed genome-wide association meta-analyses of systolic and diastolic BP incorporating gene-smoking interactions i

Fashion, Sociology of

Fashion is a social phenomenon par excellence. A simple sociological definition of fashion is 'being first with the latest.' Its underlying principle is revealed in the link between the modus derivatives and the term 'modern,' with its original meaning of 'now' or 'for today.' Fashion revolves around imitation and diffusion, and it applies to all domains of social life, though most of the research

The Cambridge Prognostic Groups for improved prediction of disease mortality at diagnosis in primary non-metastatic prostate cancer : A validation study

Background: The purpose of this study is to validate a new five-tiered prognostic classification system to better discriminate cancer-specific mortality in men diagnosed with primary non-metastatic prostate cancer. Methods: We applied a recently described five-strata model, the Cambridge Prognostic Groups (CPGs 1-5), in two international cohorts and tested prognostic performance against the curren

Everyday Life, Anthropology of

The study of everyday life is an interdisciplinary field that stands for a special interest in the commonplace and the seemingly trivial routines and activities of daily life as well as a focus on ordinary people as creative actors rather than passive consumers or objects of domination. Like few other similar concepts, the study of everyday life has been used not only as a research perspective or

Stellate cells and mesenchymal stem cells in benign mammary stroma are associated with risk factors for breast cancer - an observational study

Background: It is not known whether stromal cells in benign breast tissue can mediate risk of breast cancer. We recently described aldehyde dehydrogenase 1 A1 (ALDH1) positive (+) cells in morphologically normal breast stroma of premenopausal women, and the data indicated that their distribution is associated with clinical risk factors for breast cancer. The aim of the present study was to define

The serotonergic system in L-DOPA-induced dyskinesia : pre-clinical evidence and clinical perspective

During the last decade, the serotonergic system has emerged as a key player in the appearance of L-DOPA-induced dyskinesia in animal models of Parkinson’s disease. Clinical investigations, based on imaging and postmortem analyses, suggest that the serotonin neurons are also involved in the etiology of this complication of long-term L-DOPA treatment in parkinsonian patients. These findings have sti
