Development of an indirect immunofluorescence technique for the evaluation of generated antibody titers against Erysipelothrix rhusiopathiae in captive bottlenose dolphins (Tursiops truncatus)
submitted by moreonni 10 minutes ago - Topic: Biology
Erysipelothrix rhusiopathiae is the causative agent of erysipelas, a disease of many mammalian and avian species, mainly swine and turkeys. In cetaceans, erysipelas is considered to be the most common infection in juvenile individuals, which have not been vaccinated. Moreover, the disease manifest in both forms, the dermatologic and the acute septicemic forms, has been reported in various speci...



Optimizing Sterilization Condition for the Initiation of Sweet Potato (Ipomoea batatas) Culture in vitro
submitted by mpeipir 12 minutes ago - Topic: Biology
This study is aimed at investigating the most efficient and cost effective sterilization condition for initiation of sweet potato culture in-vitro. Different concentrations of common or local household bleach (Power zone and Dettol) and non-readily available mercuric chloride as well as variation in their duration for sterilization were used to sterilize sweet potato buds to study their effecti...

Transport effects on the vertical distribution of tropospheric ozone over western India
submitted by phainex 13 minutes ago - Topic: Geography
In situ tropospheric ozone measurements by balloon borne electrochemical concentration cell (ECC) sensors above Ahmedabad in western India from May 2003 to July 2007 are presented, along with an analysis of the transport processes responsible for the observed vertical ozone distribution. This analysis is supported by 12-day back trajectory calculations using the FLEXPART Lagrangian particle dis...

Scattering properties of modeled complex snowflakes and mixed-phase particles at microwave and millimeter frequencies
submitted by phainex 13 minutes ago - Topic: Geography
A microphysically-based algorithm (named Snow Aggregation and Melting, SAM) that models snowflakes composed of a collection of hexagonal columns by simulating a random aggregation process is presented. SAM combines together pristine columns with multiple dimensions to derive complex aggregates constrained to size-mass relationship obtained by data collected from in-situ measurements. The model ...

Characterizing the radiative impacts of precipitating snow in the ECMWF IFS global model
submitted by phainex 13 minutes ago - Topic: Geography
Global weather and climate models often exclude the effects of precipitating hydrometeors and convective core mass on radiative fluxes. In particular, many models split the ice phase into separate “cloud ice” and “snow” categories representing the smaller and larger ice particles respectively; a separation that is generally not well defined in observations. A version of the ECMWF global...



Attribution of Snow Melt Onset in Northern Canada
submitted by phainex 13 minutes ago - Topic: Geography
In the region of Earth most sensitive to climate change, spring snow melt serves as a measurable indicator of climate change and plays a strong role in the feedbacks that amplify Arctic warming. We characterize the melt season and attribute melt onset in a region of northern Canada during the spring snow melt season from 2003 to 201Melt onset dates are obtained from Advanced Microwave Scanning ...

Laboratory and field evaluations of chemical and plant-derived potential repellents against Culicoides biting midges in northern Spain
submitted by bappir234 14 minutes ago - Topic: Agriculture
The efficacy of 23 compounds in repelling Culicoides biting midges (Diptera: Ceratopogonidae), particularly Culicoides obsoletus (Meigen) females, was determined by means of a Y-tube olfactometer. The 10 most effective compounds were further evaluated in landing bioassays. The six most promising compounds (including chemical and plant-derived repellents) were evaluated at 10% and 25% concentrat...


SPES/SCOPA and MDS-UPDRS: Formulas for converting scores of two motor scales in Parkinson’s disease
submitted by bolzonmv 15 minutes ago - Topic: Health
Motor impairment in Parkinson’s disease (PD) can be evaluated with the Short Parkinson’s Evaluation Scale/Scales for Outcomes in Parkinson’s disease (SPES/SCOPA) and the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS). The aim of this study was to determine equation models for the conversion of scores from one scale to the other. 148 PD patients were evalu...

Association analysis of PARP1 polymorphisms with Parkinson’s disease
submitted by bolzonmv 15 minutes ago - Topic: Health
Alpha-synuclein accumulation in intracellular inclusions, oxidative stress and microglia-mediated inflammation in the substantia nigra are crucial events in the pathogenesis of Parkinson’s disease (PD). Poly (ADP-ribose) polymerase-1 (PARP1), a DNA-binding enzyme and transcriptional regulator, plays an important role in modulating the cellular response to oxidative stress, inflammatory stimul...


Complaints about impairments in executive functions in Parkinson's disease: The association with neuropsychological assessment
submitted by bolzonmv 15 minutes ago - Topic: Health
Impairments in executive functions are frequently reported in Parkinson's disease (PD). However, little is known about patients' experience regarding these impairments. This knowledge is crucial because if patients do not experience their cognitive impairments they do not report them to their attending neurologist. Consequently, patients might not get appropriate treatment. This study investiga...

Freezer or non-freezer: Clinical assessment of freezing of gait
submitted by bolzonmv 15 minutes ago - Topic: Health
Freezing of gait (FOG) is both common and debilitating in patients with Parkinson's disease (PD). Future pathophysiology studies will depend critically upon adequate classification of patients as being either ‘freezers’ or ‘non-freezers’. This classification should be based ideally upon objective confirmation by an experienced observer during clinical assessment. Given the known difficu...


SNCA and MAPT genes: Independent and joint effects in Parkinson disease in the Italian population
submitted by bolzonmv 15 minutes ago - Topic: Health
Significant efforts have been focused on investigating the contribution of common variants to Parkinson disease (PD) risk. Several independent GWAS and metanalysis studies have shown a genome-wide significant association of single nucleotide polymorphisms (SNPs) in the α-synuclein (SNCA) and microtubule-associated protein tau (MAPT) regions. Here we investigated the role of SNCA and MAPT as PD...

Paroxysmal kinesigenic dyskinesia: Cortical or non-cortical origin
submitted by bolzonmv 15 minutes ago - Topic: Health
Paroxysmal kinesigenic dyskinesia (PKD) is characterized by involuntary dystonia and/or chorea triggered by a sudden movement. Cases are usually familial with an autosomal dominant inheritance. Hypotheses regarding the pathogenesis of PKD focus on the controversy whether PKD has a cortical or non-cortical origin. A combined familial trait of PKD and benign familial infantile seizures has been r...

Reliability and structural validity of the Multidimensional Fatigue Inventory (MFI) in patients with idiopathic Parkinson's disease
submitted by bolzonmv 15 minutes ago - Topic: Health
The Multidimensional Fatigue Inventory (MFI) is commonly used in patients with Parkinson's disease (PD). However, most measurement properties have not been investigated in this population. The aim of this study was to investigate internal consistency, test-retest reliability, measurement error, structural validity, and floor and ceiling effects of the MFI in PD. Patients with PD (N = 153) com...
