A cognitive fingerprint in human random number generation.

Is the cognitive process of random number generation implemented via person-specific strategies corresponding to highly individual random generation behaviour? We examined random number sequences of 115 healthy participants and developed a method to quantify the similarity between two number sequences on the basis of Damerau and Levenshtein's edit distance. "Same-author" and "different author" sequence pairs could be distinguished (96.5% AUC) based on 300 pseudo-random digits alone.

Time Restricted Eating: A Dietary Strategy to Prevent and Treat Metabolic Disturbances.

Time-restricted eating (TRE), a dietary approach limiting the daily eating window, has attracted increasing attention in media and research. The eating behavior in our modern society is often characterized by prolonged and erratic daily eating patterns, which might be associated with increased risk of obesity, diabetes, and cardiovascular diseases. In contrast, recent evidence suggests that TRE might support weight loss, improve cardiometabolic health, and overall wellbeing, but the data are controversial.

Dysfunction of the key ferroptosis-surveilling systems hypersensitizes mice to tubular necrosis during acute kidney injury.

Acute kidney injury (AKI) is morphologically characterized by a synchronized plasma membrane rupture of cells in a specific section of a nephron, referred to as acute tubular necrosis (ATN). Whereas the involvement of necroptosis is well characterized, genetic evidence supporting the contribution of ferroptosis is lacking. Here, we demonstrate that the loss of ferroptosis suppressor protein 1 (Fsp1) or the targeted manipulation of the active center of the selenoprotein glutathione peroxidase 4 (Gpx4) sensitize kidneys to tubular ferroptosis, resulting in a unique morphological pattern of tubular necrosis.

Numerical analysis of trajectories in a Cassinian ion trap of second order with trap door ion inlet.

Ion traps like the Orbitrap are well known mass analyzers with very high resolving power. This resolving power is achieved with help of ions orbiting around an inner electrode for long time, in general up to a few seconds, since the mass signal is obtained by calculating the Fourier Transform of the induced signal caused by the ion motion. A similar principle is applied in the Cassinian Ion Trap of second order, where the ions move in a periodic pattern in-between two inner electrodes.

Effects of Levodopa on quality of sleep and nocturnal movements in Parkinson's Disease.

Background: Sleep disturbances are common in Parkinson's Disease (PD), with nocturnal akinesia being one of the most burdensome. Levodopa is frequently used in clinical routine to improve nocturnal akinesia, although evidence is not well proven.

Methods: We assessed associations of Levodopa intake with quality of sleep and perception of nocturnal akinesia in three PD cohorts, using the Parkinson's Disease Sleep Scale (PDSS-2) in two cohorts and a question on nocturnal immobility in one cohort.

In situ observations show vertical community structure of pelagic fauna in the eastern tropical North Atlantic off Cape Verde.

Distribution patterns of fragile gelatinous fauna in the open ocean remain scarcely documented. Using epi-and mesopelagic video transects in the eastern tropical North Atlantic, which features a mild but intensifying midwater oxygen minimum zone (OMZ), we established one of the first regional observations of diversity and abundance of large gelatinous zooplankton. We quantified the day and night vertical distribution of 46 taxa in relation to environmental conditions.

Structure, Function and Insertion of the Human Vocal Folds.

We here summarize the structures of the laryngeal vocal fold as well as its insertion structures at the anterior commissure and at the area of the vocal process and place these findings within the context of biomechanical, functional, and clinical implications.

Benign versus malignant Parkinson disease: the unexpected silver lining of motor complications.

Objective: We sought to evaluate demographic, clinical, and habits/occupational variables between phenotypic extremes in Parkinson's disease (PD).

Methods: Databases from nine movement disorders centers across seven countries were retrospectively searched for subjects meeting criteria for very slowly progressive, benign, PD (bPD) and rapidly progressive, malignant, PD (mPD). bPD was defined as Hoehn and Yahr (H&Y) stage ≤ 3, normal cognitive function, and Schwab and England (S&E) score ≥ 70 after ≥ 20 years of PD (≥ 10 years if older than 60 at PD onset); mPD as H&Y > 3, S&E score < 70, and cognitive impairment within 10 years from PD onset.

Living with Male Breast Cancer: A Qualitative Study of Men's Experiences and Care Needs.

Background: Male breast cancer (MBC) is rare, and most previous studies limited their focus on clinical aspects of the disease. Psychosocial implications and care needs of MBC patients are poorly understood.

Objectives: The aim of this study is to explore the experiences of men living with breast cancer and to identify supportive care needs.

Screening for Platelet Dysfunction and Use of Prophylactic Tranexamic Acid in Patients Undergoing Deep Brain Stimulation: A Retrospective Analysis of Incidence and Outcome of Intracranial Hemorrhage.

Introduction: The rate of intracranial hemorrhage (ICH) after deep brain stimulation (DBS) is between 1.5 and 6.1%, with prolonged deficits occurring in 0.

Short communication: Selection of extended-spectrum β-lactamase-producing Escherichia coli in dairy calves associated with antibiotic dry cow therapy-A cohort study.

Antimicrobial residues in milk have been discussed as a possible selector for Enterobacteriaceae that produce extended-spectrum β-lactamases (ESBL) in dairy herds. Such residues are found in waste milk after antibiotic treatment of mastitis, but antibiotic dry cow therapy might also lead to antibiotic residues in colostrum and in milk during early lactation. While it is known that feeding of waste milk selects ESBL bacteria in calves, this was not investigated for colostrum yet, which is supposed to contain much lower antibiotic concentrations than waste milk.

How to evaluate effects of occupational therapy - lessons learned from an exploratory randomized controlled trial.

Background: Although occupational therapy (OT) is frequently prescribed in clinical practice, there is still insufficient evidence regarding its efficacy to improve Parkinson's Disease (PD)-related activity limitations.

Objectives: To evaluate the efficacy of OT and the validity of different outcome-parameters to reflect efficacy, including gold-standard clinical rating scales and quantitative motor assessments.

Methods: 40 patients were included in an exploratory, randomized-controlled, single-blinded trial, receiving either (I) ten weeks of OT, with a main focus on motor aspects of activity limitations and a ten-week follow-up assessment or (II) no intervention.

Claudin 19 Is Regulated by Extracellular Osmolality in Rat Kidney Inner Medullary Collecting Duct Cells.

The inner medullary collecting duct (IMCD) is subject to severe changes in ambient osmolality and must either allow water transport or be able to seal the lumen against a very high osmotic pressure. We postulate that the tight junction protein claudin-19 is expressed in IMCD and that it takes part in epithelial adaptation to changing osmolality at different functional states. Presence of claudin-19 in rat IMCD was investigated by Western blotting and immunofluorescence.

Effects of Exergaming on Attentional Deficits and Dual-Tasking in Parkinson's Disease.

Impairment of dual-tasking, as an attention-based primary cognitive dysfunction, is frequently observed in Parkinson's Disease (PD). The Training-PD study investigated the efficiency of exergaming, as a novel cognitive-motor training approach, to improve attention-based deficits and dual-tasking in PD when compared to healthy controls. Eighteen PD patients and 17 matched healthy controls received a 6-week home-based training period of exergaming.

KCNJ6 variants modulate reward-related brain processes and impact executive functions in attention-deficit/hyperactivity disorder.

KCNJ6, encoding a potassium channel subunit, regulates the excitability of dopaminergic neurons and is expressed in attention-deficit/hyperactivity disorder (ADHD)-relevant brain regions. As a potential ADHD risk gene, KCNJ6, therefore, may contribute to the endophenotypic variation of the disorder. The impact of two SNPs, rs7275707 and rs6517442, both located in the transcriptional control region of KCNJ6, on reporter gene expression was explored in cultured cells.

Functions of the Microbiota for the Physiology of Animal Metaorganisms.

Animals are usually regarded as independent entities within their respective environments. However, within an organism, eukaryotes and prokaryotes interact dynamically to form the so-called metaorganism or holobiont, where each partner fulfils its versatile and crucial role. This review focuses on the interplay between microorganisms and multicellular eukaryotes in the context of host physiology, in particular aging and mucus-associated crosstalk.

Simultaneous Occurrence of Rosai-Dorfman Disease and Nodal Marginal Zone Lymphoma in a Patient with Sjögren's Syndrome.

We present an exceptionally rare case of co-occurrence of Rosai-Dorfman disease (RDD) and nodal marginal zone lymphoma (NMZL) in a 60-year-old Caucasian female with a 20-year course of Sjögren's syndrome (SS). In response to treatment for lymphoma, the patient presented a short positive response, followed by a rapid progression of the disease accompanied by the development of the peripheral facial nerve palsy. We failed to detect Epstein-Barr virus (EBV) in the NMZL/RDD sample by EBV-encoded RNA (EBER) in situ hybridization but identified genomic DNA of EBV by polymerase chain reaction.

Photoionization and photofragmentation in mass spectrometry with visible and UV lasers.

Ever since the introduction of laser technology to the field of mass spectrometry, several disciplines evolved providing solutions to challenging scientific and analytical tasks in research and industry. Among these are techniques involving multiphoton ionization such as Resonance-Enhanced Multiphoton Ionization (REMPI, R2PI) and Mass-Analyzed Threshold Ionization (MATI) spectroscopy, a variant of Zero Kinetic Energy (ZEKE) spectroscopy, that possess the ability to selectively ionize certain preselected compounds out of complex mixtures, for example, environmental matrices, with a high level of efficiency. Another key feature of multiphoton ionization techniques is the ability to control the degree of fragmentation, whereas soft ionization is most highly appreciated in most applications.

Use of a 4-week up-titration regimen of roflumilast in patients with severe COPD.

Background: The oral selective phosphodiesterase-4 inhibitor roflumilast (ROF) reduces exacerbations in patients with severe COPD. Adverse events (AEs) can cause early ROF discontinuation. Alternative dosing strategies may help patients continue their therapy.

Outcome of childhood anorexia nervosa-The results of a five- to ten-year follow-up study.

Objective: Although admissions of children with anorexia nervosa (AN) are increasing, there remains a dearth of up-to-date knowledge of the course and outcome of early-onset AN. The aim of the present study was to investigate the outcomes of patients with AN onset before the age of 14.

Method: Sixty-eight consecutive former patients who met the DSM-IV criteria for AN and who had been treated at one of three German university hospitals were asked to participate in a follow-up study.

Smoking and physical inactivity increase cancer prevalence in BRCA-1 and BRCA-2 mutation carriers: results from a retrospective observational analysis.

Background: The aim of this analysis in a pilot study population was to investigate whether we can verify seemingly harmful lifestyle factors such as nicotine and alcohol indulgence, obesity, and physical inactivity, as well as a low socioeconomic status for increased cancer prevalence in a cohort of BRCA 1 and 2 mutation carriers.

Methods: The analysis data are derived from 68 participants of the lifestyle intervention study LIBRE-1, a randomized, prospective trial that aimed to test the feasibility of a lifestyle modification in BRCA 1 and 2 mutation carriers. At study entry, factors such as medical history, lifestyle behavior, and socioeconomic status were retrospectively documented by interview and the current BMI was determined by clinical examination.

Genetic polymorphism of thymidine kinase (TK) and DNA polymerase (pol) of clinical varicella-zoster virus (VZV) isolates collected over three decades.

Background: Genotypic resistance testing of varicella-zoster virus (VZV) strains to antivirals is of high relevance in immunocompromised patients with VZV reactivations unresponsive to therapy. However, the knowledge on mutations associated with natural gene polymorphism or resistance is limited.

Objectives: To examine the genotype of the thymidine kinase (TK) and DNA polymerase (pol) of unselected clinical VZV isolates collected between 1984 and 2014 and to verify the phenotype related to novel amino acid (aa) substitutions.

Role of dual bronchodilators in COPD: A review of the current evidence for indacaterol/glycopyrronium.

In this review, we summarize the rationale for combining long-acting bronchodilators in the management of chronic obstructive pulmonary disease (COPD), and the evidence for the long-acting bronchodilator combination indacaterol/glycopyrronium (IND/GLY). Clinical practice guidelines generally recommend the use of long-acting bronchodilators in the treatment of patients with all severities of COPD, either as a first-choice or alternative-choice therapy. Combining classes of long-acting bronchodilators can result in superior improvements in lung function and clinical outcomes compared with bronchodilator monotherapy, as observed in studies of free combinations of long-acting β-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs).
