Abstract Introduction: Pigmented odontogenic lesions are rare; to date, only 60 cases have been reported in the literature. Melanocytes have been detected in a wide variety of odontogenic lesions. Several studies have discussed melanocyte presence and melanin production in odontogenic lesions, but its origin is still unclear. Therefore, the present systematic review aimed to gather information...

Background: Facial pigmentation includes various entities such as melasma, lichen planus pigmentosus (LPP), and pigmented contact dermatitis. The pathogenesis may involve certain allergens, which be responsible for causing a disturbance in the dermoepidermal junction. elimination of inciting allergens aid successful treatment these patients. Objective: aim was to detect with patch photopatch te...

tuberculosis (tb), once a disease confined to undeveloped or developing nations is currently in resurgence, which is attributable to pandemic human immunodeficiency virus (hiv) infection and immigration from endemic areas. tuberculous arthritis is difficult to diagnose early because of its atypical insidious clinical manifestations and nonspecific imaging findings. tb is also known as the ‘grea...

background :pigmented villonodularsynovitis (pvns) is characterized by the presence of inflammation and hemosiderin deposition in the synovium. two forms of pvns distinguished in the literature are diffused and localized involvements. there are controversies in the literature about the surgical management of pvns. we report our experience in the management of knee pvns at a mean follow-up of 4 ...

PGE2, Ca21, and cAMP mediate ATP activation of Cl channels in pigmented ciliary epithelial cells. Am J Physiol Cell Physiol 281: C1614–C1623, 2001.— Purines regulate intraocular pressure. Adenosine activates Cl channels of nonpigmented ciliary epithelial cells facing the aqueous humo...

The Yule-Nielsen modified Spectral Neugebauer reflection prediction model enhanced with an ink spreading model provides high accuracy when predicting reflectance spectra from ink surface coverages. In the present contribution, we try to inverse the model, i.e. to deduce the surface coverages of a printed color halftone patch from its measured reflectance spectrum. This process yields good resul...

This article describes an automated rotation rate tracking algorithm for pigmented cells that undergo rotation in a dielectrophoretic (DEP) force field. In a completely automated process, we preprocess each frame of a video sequence, then analyze the sequence frame by frame using a rotating-circle template with a block-matching algorithm, and finally estimate the rotation rate of the pigmented ...
