One important determinant of the speed and success of transition will be the efficiency of transformation and development of the infrastructure sectors. A great deal of attention has been paid to issues such as privatisation, restructuring, user prices, and terms of access in these sectors, regarding both developed and developing countries. Some issues regarding vertical restructuring are notab...

Drug design studies targeting one of the primary toxic agents in Alzheimer's disease, soluble oligomers of amyloid β-protein (Aβ), have been complicated by the rapid, heterogeneous aggregation of Aβ and the resulting difficulty to structurally characterize the peptide. To address this, we have developed [Nle(35), D-Pro(37)]Aβ(42), a substituted peptide inspired from molecular dynamics simulatio...

Canadian First Nations (FN) population experiences a high burden of tuberculosis. Vitamin D is known to enhance the expression of innate immune effectors, including cathelicidin LL-37, for protection against infections. In this study we performed longitudinal analyses to investigate the impact of vitamin D supplementation on macrophage responses to Mycobacterium tuberculosis (Mtb) lipoprotein (...

BACKGROUND Allergy is often accompanied by infections and lower levels of antimicrobial peptides (AMPs). Vitamin D has been shown to increase expression of selected AMPs. In this study we investigated whether antimicrobial peptide levels in nasal secretions of allergic asthma patients are lower than in healthy controls, and whether administration of the active form of vitamin D (1,25(OH)2D3) af...

BACKGROUND Concurrent diabetes mellitus and tuberculosis represent a significant health problem worldwide. Patients with diabetes mellitus have a high risk of tuberculosis, which may be mediated by an abnormal innate immune response due to hyperglycaemia or low vitamin D levels. METHODS In the present study, we evaluated inactive vitamin D serum levels and the monocyte response to infection w...

hCAP18/LL-37 is the sole human cathelicidin; a family of host defence peptides with key roles in innate host defence. hCAP18/LL-37 is expressed primarily by neutrophils and epithelial cells, but its production and function in the lower genital tract is largely uncharacterised. Despite the significant roles for cathelicidin in multiple organs and inflammatory processes, its impact on infections ...

constipation in children is a common health problem affecting 0.7% to 29.6% children across the world. exact etiology for developing symptoms is not clear in children and the majority is considered to have functional constipation. alteration of rectal and pelvic floor function through the brain-gut axis seems to play a crucial role in the etiology. the diagnosis is often a symptom-based clinica...
