Prevalence of immune mediated vesiculobullous lesions among patients visiting a private dental hospital with special emphasis on gingival manifestation.

Background And Aim: Vesiculobullous lesions are a group of mucocutaneous lesions that are predominantly immune-mediated but may also have a genetic or viral origin. The most common site of occurrence is buccal mucosa, whereas the number of cases involving gingiva is comparatively low. Based on the literature, although numerous studies have reported the prevalence of vesiculobullous lesions in the nonkeratinized epithelium, there is a dearth of knowledge about its occurrence in keratinized oral mucosa, especially gingiva.

A PKC that controls polyphosphate levels, pinocytosis and exocytosis, regulates stationary phase onset in Dictyostelium.

Many cells can pause their growth cycle, a topic much enriched by studies of the stationary phase (SP) of model microorganisms. Although several kinases are implicated in SP onset, whether protein kinase C has a role remains unknown. We show that Dictyostelium discoideum cells lacking pkcA entered SP at a reduced cell density, but only in shaking conditions.

PARK2 gene mutations in early onset Parkinson's disease patients of South India.

With the etiology being unclear till date, a combination of age, genetic and environmental factors are known to play a significant role in the pathogenesis of Parkinson's disease. Mutations in PARK2 gene have been implicated to cause autosomal recessive early onset PD. We analyzed the 12 coding exons of PARK2 gene in 16 early onset PD patients of South Indian ethnicity.

Altered angiogenic balance in keloids: a key to therapeutic intervention.

Keloids are manifestations of abnormal wound repair with unresolved clinical complications. An effective therapeutic regimen has not been established for keloids, and current strategies are plagued by problems such as recurrence and side effects. Keloids, being a human-specific dermal fibroproliferative disorder are characterized by an excessive accumulation of extracellular matrix (ECM), thickened basement membrane, unregulated expression of matrix metalloproteases, growth factors, and cytokines.
