Department of Neurology, P. J. Safarik University, Trieda SNP 1, 04011, Kosice, Slovak Republic; Department of Neurology, University Hospital L. Pasteur, Rastislavova 43, 04190, Kosice, Slovak Republic.

Introduction: MDS research criteria for prodromal Parkinson's disease (pPD) were published in 2015 and updated in 2019. We aimed to determine the difference in pPD patient detection rates in two cohorts recruited via gastrointestinal symptoms (PARCAS study) and the presence of a probable REM sleep behaviour disorder (PDBIOM study) using the original and updated criteria.

Methods: We evaluated all risk and prodromal markers, except genetic testing, plasma urate and physical inactivity, in both cohorts and DaT scan, diabetes mellitus type II and cognitive deficit in the PARCAS cohort. Read More

g-CN/MoS based floating solar still for clean water production by thermal/light activation of persulfate.

Chemosphere 2021 Apr 27;280:130618. Epub 2021 Apr 27.

Zhejiang Key Laboratory of Drinking Water Safety and Distribution Technology, College of Civil Engineering and Architecture, Zhejiang University, Hangzhou, 310058, PR China. Electronic address:

Currently, seawater desalination based on air-water interface solar heating has triggered significant research interests because it effectively makes use of the solar energy and avoids fossil fuel consumption. However, to prevent the volatile organic compounds (VOCs) from volatilizing with water vapor which later will liquefy and enter the condensed freshwater is still a challenge. In this work, a g-CN/MoS based floating solar still (CM-FSS) combined with thermal/light activation of persulfate (PS) at air-water interface was applied for clean freshwater production for the first time.

Methods and techniques for in vitro subcellular localization of radiopharmaceuticals and radionuclides.

Nucl Med Biol 2021 Apr 22;98-99:18-29. Epub 2021 Apr 22.

Department of Imaging Chemistry and Biology, School of Biomedical Engineering and Imaging Sciences, King's College London, London SE1 7EH, United Kingdom. Electronic address:

In oncology, the holy grail of radiotherapy is specific radiation dose deposition in tumours with minimal healthy tissue toxicity. If used appropriately, injectable, systemic radionuclide therapies could meet these criteria, even for treatment of micrometastases and single circulating tumour cells. The clinical use of α and β particle-emitting molecular radionuclide therapies is rising, however clinical translation of Auger electron-emitting radionuclides is hampered by uncertainty around their exact subcellular localisation, which in turn affects the accuracy of dosimetry.

Sensitivity of bovine tuberculosis surveillance through intradermal tests in cattle in France: An evaluation of different scenarios.

Prev Vet Med 2021 Apr 24;191:105364. Epub 2021 Apr 24.

INRAE, Oniris, BIOEPAR, 44300, Nantes, France. Electronic address:

The current situation regarding bovine tuberculosis (bTB) in Europe is spatially heterogeneous, with stagnating or increasing trends in bTB prevalence in many European regions, underlying the challenge in controlling this disease. In France, in spite of the implementation of two control programs in 2010-2012 to eradicate the disease and maintain the bTB-free status, bTB prevalence has continued to increase, underlying the need to reinforce and adapt surveillance measures. The goal of this study was to evaluate the effectiveness of bTB surveillance in high-risk areas in metropolitan France, with an emphasis on the criteria to select herds and animals within herds in the context of programmed surveillance and movement testing.

Encephalocele-Associated Drug Resistant Epilepsy of Adult-Onset: Diagnosis, Management, and Outcomes.

World Neurosurg 2021 May 5. Epub 2021 May 5.

Epileptogenic encephaloceles, most frequently located in the temporal lobe, are a known lesional cause of focal epilepsy. Data are limited regarding diagnosis, management, and outcomes of patients with epilepsy in the setting of an encephalocele, as the literature is mostly comprised of case reports, case series, and retrospective studies. We conducted a broad literature review for manuscripts related to encephaloceles and epilepsy regardless of level of evidence. Read More

Clinical presentation, diagnostic findings, and long-term survival time in 182 dogs with meningoencephalitis of unknown origin from Central Europe that were administered glucocorticosteroid monotherapy.

Top Companion Anim Med 2021 May 5:100539. Epub 2021 May 5.

Institute of Mathematics and Statistics, Masaryk University, Brno, 60200 Czech Republic.

Canine non-infectious inflammatory meningoencephalomyelitis is termed meningoencephalomyelitis of unknown origin (MUO) and may affect dogs of every breed at any age. Treatment with immunosuppressive medication, the survival time based on MRI, and cerebrospinal fluid (CSF) findings has been widely reported; however, these studies only included a small number of patients, or they are summaries from the literature. Therefore, the aim of this study was to compare the clinical presentation, diagnostic findings, treatment protocol and long-term survival time in many dogs diagnosed with MUO in one clinic with previously published studies.

Clinical validation of Whole Genome Sequencing for cancer diagnostics.

J Mol Diagn 2021 May 5. Epub 2021 May 5.

Hartwig Medical Foundation, Science Park 408, 1098 XH Amsterdam, the Netherlands; Center for Molecular Medicine and Oncode Institute, University Medical Center Utrecht, Heidelberglaan 100, 3584 CX Utrecht, the Netherlands.

Whole genome sequencing (WGS) using fresh frozen tissue and matched blood samples from cancer patients is becoming in reach as the most complete genetic tumor test. With a trend towards the availability of small biopsies and the need to screen an increasing number of (complex) biomarkers, the use of a single all-inclusive test is preferred over multiple consecutive assays. To meet high-quality diagnostics standards, we optimized and clinically validated WGS sample and data processing procedures resulting in a technical success rate of 95. Read More
