The psychosocial consequences of pediatric multiple sclerosis.

Although psychological distress and cognitive dysfunction are well documented in adults with multiple sclerosis (MS), they are poorly understood in children with the disease. Psychosocial difficulty experienced by children and adolescents with MS involves factors common to all chronic illnesses in children, as well as MS-specific factors. The psychosocial manifestations of the disease may affect the patient's self-image, role functioning, mood, and cognition to adversely affect schooling, interpersonal relationships, and treatment compliance. Furthermore, the impact of having a family member with MS may affect overall family functioning. Assessment and interventions for psychosocial and cognitive problems in pediatric MS should be multidisciplinary in nature and address the child's functioning at home, school, and among peers, as well as the effect on the family.

Stimulation of benzyladenine-induced in vitro shoot organogenesis and endogenous proline in melon (Cucumis melo L.) by fish protein hydrolysates in combination with proline analogues.

A previous study demonstrated that proline is beneficial for improving melon in vitro shoot organogenesis. A natural source of proline and proline precursors can be obtained from fish protein hydrolysates (FPH), a byproduct of the fishery industry. Proline analogues azetidine-2-carboxylate and hydroxyproline in combination with standardized FPH were used to stimulate proline synthesis and benzyladenine-induced shoot organogenesis by exploiting the proposed proline-linked pentose phosphate pathway (PPP). In the presence of elevated levels of endogenous proline, potential stimulation of cytokinins and auxin may occur via the PPP and shikimate pathways, respectively. Treatments with FPH singly and in combination with the above proline analogues significantly increased the endogenous proline content and the extent of differentiation, suggesting that in vitro organogenesis is closely linked to proline synthesis, strengthening the hypothesis that purine metabolism via the proline-linked PPP may be important for organogenesis. Thioproline addition resulted in increased proline levels but without corresponding stimulation of organogenesis. This study also provides potential use of fishery waste for value-added application in plant micropropagation industry.
