Evolving stoma appliances to improve patient outcomes and increase stoma acceptance.

Adjusting to life with a stoma can be difficult physically and emotionally. Preoperative counselling, where possible in cases of elective surgery, is fundamental to preparing those facing stoma formation, and a lack of support can be detrimental and can increase the risk of stoma patients experiencing complications. The stoma care nurse specialist (SCN) uses a range of clinical skills and specialist knowledge to support a patient through their surgical pathway; this is important for helping patients gain the skills and confidence to care for their stoma and reduce the risk of stoma-related complications.

Applying association mapping and genomic selection to the dissection of key traits in elite European wheat.

We show the application of association mapping and genomic selection for key breeding targets using a large panel of elite winter wheat varieties and a large volume of agronomic data. The heightening urgency to increase wheat production in line with the needs of a growing population, and in the face of climatic uncertainty, mean new approaches, including association mapping (AM) and genomic selection (GS) need to be validated and applied in wheat breeding. Key adaptive responses are the cornerstone of regional breeding.

Tyrosine phosphorylation of the Rho guanine nucleotide exchange factor Trio regulates netrin-1/DCC-mediated cortical axon outgrowth.

The chemotropic guidance cue netrin-1 mediates attraction of migrating axons during central nervous system development through the receptor Deleted in Colorectal Cancer (DCC). Downstream of netrin-1, activated Rho GTPases Rac1 and Cdc42 induce cytoskeletal rearrangements within the growth cone. The Rho guanine nucleotide exchange factor (GEF) Trio is essential for Rac1 activation downstream of netrin-1/DCC, but the molecular mechanisms governing Trio activity remain elusive.

The missing sense modality: the immune system.

The five senses were handed down by Aristotle. I argue that it has only taken two millennia to recognize that the immune system has been the hidden sensory modality. The immune system completes the range of operation allowing detection of meaningful entities at all distances, from very near to very far.

Sephardic signature in haplogroup T mitochondrial DNA.

A rare combination of mutations within mitochondrial DNA subhaplogroup T2e is identified as affiliated with Sephardic Jews, a group that has received relatively little attention. Four investigations were pursued: Search of the motif in 250 000 control region records across 8 databases, comparison of frequencies of T subhaplogroups (T1, T2b, T2c, T2e, T4, T(*)) across 11 diverse populations, creation of a phylogenic median-joining network from public T2e control region entries, and analysis of one Sephardic mitochondrial full genomic sequence with the motif. It was found that the rare motif belonged only to Sephardic descendents (Turkey, Bulgaria), to inhabitants of North American regions known for secret Spanish-Jewish colonization, or were consistent with Sephardic ancestry.

A perception theory in mind-body medicine: guided imagery and mindful meditation as cross-modal adaptation.

A new theory of mind-body interaction in healing is proposed based on considerations from the field of perception. It is suggested that the combined effect of visual imagery and mindful meditation on physical healing is simply another example of cross-modal adaptation in perception, much like adaptation to prism-displaced vision. It is argued that psychological interventions produce a conflict between the perceptual modalities of the immune system and vision (or touch), which leads to change in the immune system in order to realign the modalities.

The activation of ezrin-radixin-moesin proteins is regulated by netrin-1 through Src kinase and RhoA/Rho kinase activities and mediates netrin-1-induced axon outgrowth.

The receptor Deleted in Colorectal Cancer (DCC) mediates the attractive response of axons to the guidance cue netrin-1 during development. On netrin-1 stimulation, DCC is phosphorylated and induces the assembly of signaling complexes within the growth cone, leading to activation of cytoskeleton regulators, namely the GTPases Rac1 and Cdc42. The molecular mechanisms that link netrin-1/DCC to the actin machinery remain unclear.

Novel α1 and γ2 GABAA receptor subunit mutations in families with idiopathic generalized epilepsy.

Epilepsy is a heterogeneous neurological disease affecting approximately 50 million people worldwide. Genetic factors play an important role in both the onset and severity of the condition, with mutations in several ion-channel genes being implicated, including those encoding the GABA(A) receptor. Here, we evaluated the frequency of additional mutations in the GABA(A) receptor by direct sequencing of the complete open reading frame of the GABRA1 and GABRG2 genes from a cohort of French Canadian families with idiopathic generalized epilepsy (IGE).

Mystery of the anti-McCollough effect.

The McCollough Effect (ME) is a complex perceptual aftereffect that remains of interest half a century after its discovery. It is argued that a recently reported variant, dubbed the anti-McCollough effect, is not the reverse of the ME, with aftereffect colors in the same direction as the inducing stimuli. A red-horizontal stimulus leads to a reddish aftereffect not because of red-horizontal parings, but despite them.

Identification of a novel di-leucine motif mediating K(+)/Cl(-) cotransporter KCC2 constitutive endocytosis.

The neuron-specific potassium-chloride cotransporter 2 (KCC2) plays a crucial role, by controlling chloride extrusion, in the development and maintenance of inhibitory neurotransmission. Although it is now well established that activity-dependent mechanisms can down regulate KCC2 gene expression, the role of post-translational mechanisms in controlling KCC2 expression, specifically at the cell-surface, are poorly understood. We therefore set out to identify the mechanisms and motifs regulating KCC2 endocytosis, one important pathway that may control KCC2 membrane expression.

Compartmentalized DCC signalling is distinct from DCC localized to lipid rafts.

Background Information: Netrin-1 is a bi-functional cue that attracts or repels different classes of neurons during development. The netrin-1 receptor DCC (deleted in colorectal cancer) acts as a tyrosine kinase-associated receptor to mediate the attractive response towards netrin-1. The lipid raft-localized Src family kinase Fyn is required for DCC-mediated axon guidance.

Is prism adaptation "for" growth?

The assumption that prism adaptation mechanisms evolved for developmental plasticity was questioned by analyzing natural transformations (magnification, rotation, displacement) of the arm and shoulder. Accommodating ordinary movement was found to be a closer match to prisms than transformations caused by growth. In addition, overlap between equations of movement and growth may point to a distal function of adaptation that is very general.

Can a space-perception conflict be solved with three sense modalities?

A cross-modal conflict over location was resolved in an unexpected way. When vision and proprioception provide conflicting information, which modality should dominate is ambiguous. A visual-proprioceptive conflict was created with a prism and, to logically disambiguate the problem, auditory information was added that either agreed with vision (group 1), agreed with proprioception (group 2), or was absent (group 3).

The UBL domain of PLIC-1 regulates aggresome formation.

Defects in protein folding and the proteasomal pathway have been linked with many neurodegenerative diseases. PLIC-1 (protein linking IAP to the cytoskeleton) is a ubiquitin-like protein that binds to the ubiquitin-interacting motif (UIM) of the proteasomal subunit S5a. Here, we show that PLIC-1 also binds to the UIM proteins ataxin 3--a deubiquitinating enzyme--HSJ1a--a co-chaperone--and EPS15 (epidermal growth factor substrate 15)--an endocytic protein.

Analysis of a constraint on perception, cognition, and development: one object, one place, one time.

It has become increasingly common for theories to rely on a constraint that 1 object cannot be in more than 1 place at the same time. Analysis suggests that a 1 object-1 place-1 time constraint as literally stated is false, that a modified constraint is biased toward the visual modality, that it may not be a correct description of the physical world, is not true of how objects must appear on sensory surfaces, and does not mean that 2 simultaneous spatially separated samples must be interpreted as 2 different objects, even for vision. However, once such object numerosity or identity is determined in some other way, then a modified constraint can be used to trigger learning, such as prism adaptation.

The amino terminus of the glial glutamate transporter GLT-1 interacts with the LIM protein Ajuba.

We have identified a cytoplasmic LIM protein, Ajuba, which interacts with the amino terminus of GLT-1, the most abundant plasma membrane glutamate transporter in the brain. Ajuba has a cytoplasmic location when expressed alone in COS cells, but translocates to colocalize with GLT-1 at the plasma membrane when GLT-1 is coexpressed. Ajuba is expressed in cerebellum, cortex, hippocampus, and retina and also in organs outside the CNS.

GABA(A) receptor cell surface number and subunit stability are regulated by the ubiquitin-like protein Plic-1.

Controlling the number of functional gamma-aminobutyric acid A (GABA(A)) receptors in neuronal membranes is a crucial factor for the efficacy of inhibitory neurotransmission. Here we describe the direct interaction of GABA(A) receptors with the ubiquitin-like protein Plic-1. Furthermore, Plic-1 is enriched at inhibitory synapses and is associated with subsynaptic membranes.
