A simple method for the quantitation of the stem cells derived from human exfoliated deciduous teeth using a luminescent cell viability assay.

Stem cells from human exfoliated deciduous teeth are a population of highly proliferative postnatal stem cells and have been characterized as multipotent stem cells. In this study we developed a fast and sensitive method for stem cells derived from human exfoliated deciduous teeth count, using a luminescent viability assay. We isolated stem cells from normal exfoliated deciduous teeth using collagenase/dispase digestions solutions.

Antiidiotypic antibodies carrying the "internal image" of peptide YIGSR inhibit spontaneous metastasis of Lewis lung carcinoma in mice.

Background: It has been reported that the laminin derivative synthetic peptide YIGSR can bind to a metastasis-associated laminin receptor and inhibit experimental metastasis. Several antiidiotypic antibody (anti-Id) vaccines have been used in clinical trials with promising results. We used an anti-Id vaccine based on peptide YIGSR for the inhibition of spontaneous metastasis in Lewis Lung carcinoma-bearing mice.

"Hanseniaspora uvarum" the ultrastructural morphology of a rare ascomycete, isolated from oral thrush.

Superficial fungal infections, including oral thrush, often affect aged full denture wearers and many individuals over 65 years old. The aim of this study was to examine the ultrastructural morphology of a very rare yeast, named Hanseniaspora uvarum/guillermondi, member of the Ascomycetes family, whose pathogenesis and behaviour is not widely known. The yeast was isolated from whitish lesions of the buccal mucosa of an 70 years old woman.

Histochemical localization of salivary glycoproteins in the submandibular gland of aging rats.

It is known that submandibular glands produce serous saliva in the serous demilune cells and mucous saliva in the mucous acinar cells which is a viscous, rich in glycoproteins substance. The aim of this study was the comparative histochemical investigation of acid and neutral salivary glycoproteins in the acinar cells of the submandibular gland in adult and aging rats. Three groups of female Wistar rats were studied: a) young adult rats, 3 months old, b) aged rats 25 months old, c) aged rats 30 months old.
