Urinary dysfunction (UD) is a common non-motor feature of Parkinson's disease (PD), and might be secondary to neurodegeneration involving cortical and subcortical brain areas. The possible link between UD and cognitive deficits has never been examined in frontal cortex impairment, and is still not completely understood in PD. In the present study, 94 PD patients underwent a comprehensive motor, cognitive and non-motor assessment. It was shown that 55.3% of patients reported UD, of which 17% needed specific urological treatment...

Individual Placement and Support (IPS) is an evidence-based employment model for people with severe mental illness, but it has not been evaluated for clients enrolled in substance abuse treatment programs. This study evaluated the effectiveness of IPS for people with opioid use disorders enrolled in an opioid treatment program. Within a randomized controlled experiment, 45 patients receiving methadone maintenance therapy were assigned to either IPS or a 6-month waitlist. The waitlist group received IPS after 6 months...

Anodal transcranial direct current stimulation (tDCS) of the prefrontal cortex has been repeatedly shown to improve working memory (WM). Since patients with attention deficit hyperactivity disorder (ADHD) are characterized by both underactivation of the prefrontal cortex and deficits in WM, the modulation of prefrontal activity with tDCS in ADHD patients may increase their WM performance as well as improve the activation and connectivity of the WM network. In the present study, this hypothesis was tested using a double-blind sham-controlled experimental design...

In 1953, investigators at the Rocky Mountain Laboratories in Hamilton, Montana, described the isolation of a spotted fever group Rickettsia (SFGR) species from Dermacentor parumapertus collected from black-tailed jackrabbits (Lepus californicus) in northern Nevada. Several decades later, investigators characterized this SFGR by using mouse serotyping methods and determined that it represented a distinct rickettsial serotype, related closely to Rickettsia parkeri; nonetheless, the parumapertus agent was not further characterized or studied...

Marine algae produce varieties of glycans, which fulfill diverse biological functions and fuel the carbon and energy demand of heterotrophic microbes. A common approach to analyze marine organic matter uses acid to hydrolyze its glycans into measurable monosaccharides. These, however, may derive from different glycans that are built with the same monosaccharides, hence this approach does not distinguish between glycans in natural samples. Here we use enzymes to selectively digest and thereby quantify laminarin in particulate organic matter...

BACKGROUND: Excessive ethanol consumption remains an important health concern and effective treatments are lacking. The central oxytocin system has emerged as a potentially important therapeutic target for alcohol and drug addiction. These studies tested the hypothesis that oxytocin reduces ethanol consumption. METHODS: Male C57BL/6J mice were given access to ethanol (20% v/v) using a model of binge-like drinking ("drinking-in-the-dark") that also included the use of lickometer circuits to evaluate the temporal pattern of intake as well as 2-bottle choice drinking in the home cage...

OBJECTIVES: The aim of this study was to evaluate the diagnostic accuracy of a multipurpose image analysis software based on deep learning with artificial neural networks for the detection of breast cancer in an independent, dual-center mammography data set. MATERIALS AND METHODS: In this retrospective, Health Insurance Portability and Accountability Act-compliant study, all patients undergoing mammography in 2012 at our institution were reviewed (n = 3228). All of their prior and follow-up mammographies from a time span of 7 years (2008-2015) were considered as a reference for clinical diagnosis...

In search of antiparasitic agents, we here identify arylmethylamino steroids as potent compounds and characterize more than 60 derivatives. The lead compound 1o is fast acting and highly active against intraerythrocytic stages of chloroquine-sensitive and resistant Plasmodium falciparum parasites (IC50 1-5 nM) as well as against gametocytes. In P. berghei-infected mice, oral administration of 1o drastically reduces parasitaemia and cures the animals. Furthermore, 1o efficiently blocks parasite transmission from mice to mosquitoes...

PURPOSE: A degenerative meniscus lesion is a slowly developing process typically involving a horizontal cleavage in a middle-aged or older person. When the knee is symptomatic, arthroscopic partial meniscectomy has been practised for a long time with many case series reporting improved patient outcomes. Since 2002, several randomised clinical trials demonstrated no additional benefit of arthroscopic partial meniscectomy compared to non-operative treatment, sham surgery or sham arthroscopic partial meniscectomy...

The continuous presence of recombinant human bone morphogenetic protein 2 (rhBMP-2) inside a scaffold may be crucial to the outcome in bone tissue engineering. This study investigated whether the release of the growth factor rhBMP-2 via different continuous application schemes influences histomorphological aspects of the hard and soft tissues induced. Three-dimensionally printed hydroxyapatite scaffolds were implanted into one latissimus dorsi muscle of 42 female Lewis rats. Simultaneously implanted mini-osmotic pumps were used to provide a continuous application of rhBMP-2 over 1, 2, or 4 weeks (total dose 200μg)...

BACKGROUND: Multi-copy gene integration into microbial genomes is a conventional tool for obtaining improved gene expression. For Penicillium chrysogenum, the fungal producer of the beta-lactam antibiotic penicillin, many production strains carry multiple copies of the penicillin biosynthesis gene cluster. This discovery led to the generally accepted view that high penicillin titers are the result of multiple copies of penicillin genes. Here we investigated strain P2niaD18, a production line that carries only two copies of the penicillin gene cluster...

BACKGROUND: To review the palliative radiation fractionation regimens, trends and survival of men within the National Cancer Database (NCDB) diagnosed with prostate cancer and bony metastases. METHODS: A total of 3,871 patients from the NCDB were included in the analysis (patients treated from 2004-2012). The following fractionation regimens were analyzed [8 Gy × 1, 4 Gy × 5 (short course radiation therapy)], were compared to 3 Gy × 10, 2.50 Gy × 14-15 and 2 Gy × 20-30 (long course radiation therapy)...

Cutaneous leishmaniasis caused by Leishmania mexicana is associated with an important inflammatory response. We here analyzed the kinetics of Th17 cells and neutrophils in earlobe lesions caused by Leishmania mexicana throughout 90 days of disease progresion in susceptible BALB/c and semi-resistant C57BL/6 mice infected with 1x10(5) Leishmania mexicana promastigotes. Cells in the lesions were extracted and quantified by flow cytometry, whereas their distribution in the tissues in relation to the parasites was analyzed by immunohistochemistry...

Chad Peltier, Mark W Becker
Critical real-world visual search tasks such as radiology and baggage screening rely on the detection of rare targets. When targets are rare, observers search for a relatively short amount of time and have a high miss rate, a pattern of results known as the low prevalence effect. Attempts to improve the search for rare targets have been unsuccessful or resulted in an increase in detections at the price of more false alarms. As an alternative to improving visual search performance through experimental manipulations, an individual differences approach found that those with higher working memory capacity were better at finding rare targets...

OBJECTIVE: We aimed to determine the effect of elevated BMI over time on the progression to type 1 diabetes in youth. RESEARCH DESIGN AND METHODS: We studied 1,117 children in the TrialNet Pathway to Prevention cohort (autoantibody-positive relatives of patients with type 1 diabetes). Longitudinally accumulated BMI above the 85th age- and sex-adjusted percentile generated a cumulative excess BMI (ceBMI) index. Recursive partitioning and multivariate analyses yielded sex- and age- specific ceBMI thresholds for greatest type 1 diabetes risk...

Since 1980, mosquito breeding habitats in the Upper Rhine Valley were routinely treated with Bacillus thuringiensis var. israelensis (Bti). Bti is considered to significantly reduce the number of mosquitoes, and - especially when used in higher dosages - to be toxic to other Nematocera species, e.g. Chironomidae, which could be food sources for aerial feeding predators. To investigate direct and indirect effects of routine Bti treatment on food sources for aerial feeding predators, the availability of flying insects in treated and untreated areas was compared...
