Background: Elimination disorders are highly prevalent in childhood and often associated with clinically relevant comorbid psychological disorders. The aim of this study is to determine if, and to what extent, children with elimination disorders show higher internalizing and externalizing problems than their healthy peers.

Methods: A multistep literature search was performed from database inception until May 1st, 2022.

Longitudinal change in neurocognitive functioning in children and adolescents at clinical high risk for psychosis: a systematic review.

Clinical high risk of psychosis (CHR-P) population has become an attractive area of interest in preventing transitions to psychosis. The consequences of developing a psychotic disorder may be worse in cases of early onset. Thus, childhood and adolescence represent a critical developmental window, where opportunities to gain social and adaptive abilities depend on the individuals' neurocognitive performance.

Remodeling of the Actin/Spectrin Membrane-associated Periodic Skeleton, Growth Cone Collapse and F-Actin Decrease during Axonal Degeneration.

Axonal degeneration occurs in the developing nervous system for the appropriate establishment of mature circuits, and is also a hallmark of diverse neurodegenerative diseases. Despite recent interest in the field, little is known about the changes (and possible role) of the cytoskeleton during axonal degeneration. We studied the actin cytoskeleton in an in vitro model of developmental pruning induced by trophic factor withdrawal (TFW).

Automated quantification of protein periodic nanostructures in fluorescence nanoscopy images: abundance and regularity of neuronal spectrin membrane-associated skeleton.

Fluorescence nanoscopy imaging permits the observation of periodic supramolecular protein structures in their natural environment, as well as the unveiling of previously unknown protein periodic structures. Deciphering the biological functions of such protein nanostructures requires systematic and quantitative analysis of large number of images under different experimental conditions and specific stimuli. Here we present a method and an open source software for the automated quantification of protein periodic structures in super-resolved images.

Effects of exogenous nitric oxide on growth, proline accumulation and antioxidant capacity in Cakile maritima seedlings subjected to water deficit stress.

Nitric oxide (NO) - an endogenous signalling molecule in plants and animals - mediates responses to biotic and abiotic stresses. In the present study, we examined the role of exogenous application of NO in mediating stress responses in Cakile maritima Scop. seedlings under water deficit stress using sodium nitroprusside (SNP) as NO donor and as a pre-treatment before the application of stress.

Hydrogen peroxide produced by NADPH oxidases increases proline accumulation during salt or mannitol stress in Arabidopsis thaliana.

Many plants accumulate proline, a compatible osmolyte, in response to various environmental stresses such as water deficit and salinity. In some stress responses, plants generate hydrogen peroxide (H2 O2 ) that mediates numerous physiological and biochemical processes. The aim was to study the relationship between stress-induced proline accumulation and H2 O2 production.

Involvement of Phosphatidylinositol 3-kinase in the regulation of proline catabolism in Arabidopsis thaliana.

Plant adaptation to abiotic stresses such as drought and salinity involves complex regulatory processes. Deciphering the signaling components that are involved in stress signal transduction and cellular responses is of importance to understand how plants cope with salt stress. Accumulation of osmolytes such as proline is considered to participate in the osmotic adjustment of plant cells to salinity.

Biochemical characterization of proline dehydrogenase in Arabidopsis mitochondria.

Proline has multiple functions in plants. Besides being a building block for protein biosynthesis proline plays a central role in the plant stress response and in further cellular processes. Here, we report an analysis on the integration of proline dehydrogenase (ProDH) into mitochondrial metabolism in Arabidopsis thaliana.

Phospholipases C and D modulate proline accumulation in Thellungiella halophila/salsuginea differently according to the severity of salt or hyperosmotic stress.

Proline accumulation is one of the most common responses of plants to environmental constraints. Thellungiella halophila/salsuginea, a model halophyte, accumulates high levels of proline in response to abiotic stress and in the absence of stress. Recently, lipid signaling pathways have been shown to be involved in the regulation of proline metabolism in Arabidopsis thaliana.

[Long-term results of the treatment of urinary incontinence with bulbar implantation of artificial urinary sphincter in men: a single-center experience].

Objective: To report the functional results and morbidity after implantation of bulbar artificial urinary sphincter (AUS) in incontinent men with at least 5 years of follow-up.

Patients And Methods: The files of patients treated between 1984 and 2003 by setting up a SAU at bulbar location were reviewed. The following data were recorded: age, etiology of incontinence, intra-operative complications.

A new method for accurately measuring Delta(1)-pyrroline-5-carboxylate synthetase activity.

Proline is a key factor in plant adaptation to environmental stresses. The Delta(1)-pyrroline-5-carboxylate synthetase catalyzes the first committed step and the rate-limiting step for proline biosynthesis in both plants and mammals. This enzyme catalyzes the reduction of glutamate to pyrroline-5-carboxylate in two sequential steps including the phosphorylation and the reduction of its precursor.

Comparative salt tolerance analysis between Arabidopsis thaliana and Thellungiella halophila, with special emphasis on K(+)/Na(+) selectivity and proline accumulation.

The eco-physiology of salt tolerance, with an emphasis on K(+) nutrition and proline accumulation, was investigated in the halophyte Thellungiella halophila and in both wild type and eskimo-1 mutant of the glycophyte Arabidopsis thaliana, which differ in their proline accumulation capacity. Plants cultivated in inert sand were challenged for 3 weeks with up to 500mM NaCl. Low salinity significantly decreased A.

Calcium signaling via phospholipase C is essential for proline accumulation upon ionic but not nonionic hyperosmotic stresses in Arabidopsis.

Proline (Pro) accumulation occurs in various plant organisms in response to environmental stresses. To identify the signaling components involved in the regulation of Pro metabolism upon water stress in Arabidopsis (Arabidopsis thaliana), a pharmacological approach was developed. The role of phosphoinositide-specific phospholipases C (PLCs) in Pro accumulation was assessed by the use of the aminosteroid U73122, a commonly employed specific inhibitor of receptor-mediated PLCs.
