Blood can form a gel when there are high concentrations of proteins, such as IgM and/or IgG antibodies, that precipitate at low temperatures (cryoglobulins) or agglutinate red blood cells (cold agglutinins) (1, 2 ). A bone marrow biopsy performed on this patient revealed Waldenström macroglobulinemia, which produces large amounts of IgM (3, 4). Warming this patient’s sample in a water bath, kee...

Immunofluorescence sections of cells embedded within a micropatterned collagen gel. Cells generate forces within a tissue that can feedback to regulate the accumulation of cytoskeletal proteins such as actin (green) and structural matrix proteins such as fibronectin or tenascin C (red). These forces can be measured using elastomeric cantilevers (white) that deflect in response to tissue forces....

A quick, reliable, purification procedure was developed for purifying both benzyl alcohol dehydrogenase and benzaldehyde dehydrogenase II from a single batch of Acinetobacter calcoaceticus N.C.I.B. 8250. The procedure involved disruption of the bacteria in the French pressure cell and preparation of a high-speed supernatant, followed by chromatography on DEAE-Sephacel, affinity chromatography o...

OBJECTIVES The aim of this study was to evaluate the intrapulpal temperature variation after bleaching treatment with 35% hydrogen peroxide using different sources of activation. MATERIAL AND METHODS Twenty-four human teeth were sectioned in the mesiodistal direction providing 48 specimens, and were divided into 4 groups (n=12): (G1) Control - Bleaching gel without light activation, (G2) Blea...

This work was aimed to study the stability, and activity of topical products formulated with red leaves extract Vitis Vinifera encapsulated in liposomes, produced, Tuscany (Italy). Recent studies have suggested a possible moisturizing elasticizing Vinifera. For such characteristics appears an appropriate ingredient be used preparations for treatment skin hydration. The liposomes then incorporat...
