BACKGROUND: Predictive testing for Huntington's disease (HD) has been available for individuals at risk of HD by direct mutation analysis since 1993. International Predictive test guidelines recommend that support is offered following the result regardless of test outcome. However, there is lack of an evidence base regarding what this support should look like and how it might work in practice. OBJECTIVE: A service improvement initiative looked at the feasibility of offering a narrative group session co-facilitated by a genetic counsellor and clinical psychologist, to individuals who had tested mutation negative for HD...

Acid proteins capable of nucleating Ca2+ and displaying aggregation capacity play key roles in the formation of calcium carbonate biominerals. The helix-loop helix EF-hands are the most common Ca2+ -binding motifs in proteins. Calcium is bound by the loop region. These motifs are found in many proteins that are regulated by calcium. Gad m 1, an Atlantic cod β-parvalbumin isoform, is a monomeric EF-hand protein that acts as a Ca2+ buffer in fish muscle; the neutral and acid apo-forms of this protein can form amyloids...

GABAergic interneuron loss, maturational delay or imbalance of glutamatergic to GABAergic signaling has been implicated in several neuropsychiatric disorders including Tourette syndrome and attention-deficit/hyperactivity disorder (ADHD). In schizophrenia, decreases in parvalbumin (PV), somatostatin (Sst) and glutamic acid decarboxylase (GAD) RNA have been observed and seem to indicate a failure in maturation in PV and Sst neurons. In Tourette syndrome, which has a high level of comorbid ADHD, reduced numbers of parvalbumin expressing neurons have been observed in the basal ganglia of affected patients...

The neural mechanisms underlying alcohol dependence are not well-understood. GABAergic neurons in the ventral tegmental area (VTA) are a relevant target for ethanol. They are inhibited by ethanol at physiologically-relevant levels in vivo and display marked hyperexcitability during withdrawal. In the present study, we examined the effects of the GABA(A) receptor agonist muscimol on VTA neurons ex vivo following withdrawal from acute and chronic ethanol exposure. We used standard cell-attached mode electrophysiology in the slice preparation to evaluate the effects of muscimol on VTA GABA neuron firing rate following exposure to acute and chronic ethanol in male CD-1 GAD-67 GFP mice...

BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

BACKGROUND: Babesia spp. and Hepatozoon spp. are apicomplexan parasites that infect a variety of animals, including canids. Their life-cycle includes an invertebrate hematophagous vector as a definitive host and vertebrates as intermediate hosts. The aims of this study were to investigate the prevalence and risk factors for Babesia spp. and Hepatozoon spp. infections in wild golden jackals (Canis aureus) and red foxes (Vulpes vulpes) in Israel and to compare spleen with blood sample polymerase chain reaction (PCR) for the detection of infection...

BACKGROUND: Cardiovascular magnetic resonance (CMR) imaging has been used to visualise post-ablation atrial scar (PAAS), generally employing a three-dimensional (3D) late gadolinium enhancement (LGE) technique. However the reproducibility of PAAS imaging has not been determined. This cross-over study is the first to investigate the reproducibility of the technique, crucial for both future research design and clinical implementation. METHODS: Forty subjects undergoing first time ablation for atrial fibrillation (AF) had detailed CMR assessment of PAAS...

BACKGROUND: The severity of canine leishmaniosis (CanL) due to Leishmania infantum might be affected by other vector-borne organisms that mimic its clinical signs and clinicopathological abnormalities. The aim of this study was to determine co-infections with other vector-borne pathogens based on serological and molecular techniques in dogs with clinical leishmaniosis living in Spain and to associate them with clinical signs and clinicopathological abnormalities as well as disease severity...

BACKGROUND: Cognitive models of generalized anxiety disorder (GAD) suggest that maladaptive behaviours may contribute to the maintenance of the disorder; however, little research has concentrated on identifying and measuring these behaviours. To address this gap, the Worry Behaviors Inventory (WBI) was developed and has been evaluated within a classical test theory (CTT) approach. AIMS: As CTT is limited in several important respects, this study examined the psychometric properties of the WBI using an Item Response Theory approach...

Enteropathogenic Escherichia coli (EPEC) subvert host cell signaling pathways by injecting effector proteins via a Type 3 Secretion System (T3SS). The T3SS-dependent EspB protein is a multi-functional effector protein, which contributes to adherence and translocator pore formation and after injection exhibits several intracellular activities. In addition, EspB is also secreted into the environment. Effects of secreted EspB have not been reported thus far. As a surrogate for secreted EspB we employed recombinant EspB (rEspB) derived from the prototype EPEC strain E2348/69 and investigated the interactions of the purified protein with different human epithelial and immune cells including monocytic THP-1 cells, macrophages, dendritic cells, U-937, epithelial T84, Caco-2, and HeLa cells...

BACKGROUND: Both adverse early life-events and distressed personality are associated with an increased cardiovascular risk. As there is an important link between these psychological factors, we investigated how these might cluster in sex-specific psychological profiles. We further examined the association of these profiles with cardiovascular risk markers. METHOD: 446 women (mean age = 49.8 ± 17.9 years) and 431 men (mean age = 49.4 ± 17.5 years) from the Dutch general population completed questionnaires on demographics, adverse early life-events (ETI), Type D personality (DS14), anxiety (GAD-7) and depressive (PHQ-9) symptoms, and traditional cardiovascular risk markers...

BACKGROUND: Congestion is the main reason for hospital admission for acute decompensated heart failure (ADHF). A better understanding of the clinical course of congestion and factors associated with decongestion are therefore important. We studied the clinical course, predictors and prognostic value of congestion in a cohort of patients admitted for ADHF by including different indirect markers of congestion (residual clinical congestion, brain natriuretic peptides (BNP) trajectories, hemoconcentration or diuretic response)...
