TL;DR: This manuscript focuses on the NCCN Guidelines Panel recommendations for the workup, primary treatment, risk reduction strategies, and surveillance specific to DCIS.
Abstract: Ductal carcinoma in situ (DCIS) of the breast represents a heterogeneous group of neoplastic lesions in the breast ducts. The goal for management of DCIS is to prevent the development of invasive breast cancer. This manuscript focuses on the NCCN Guidelines Panel recommendations for the workup, primary treatment, risk reduction strategies, and surveillance specific to DCIS.

TL;DR: The studies described here form the basis for investigations into the molecular mechanisms of Candida biofilm biology and antifungal resistance and provide the means to design novel therapies for biofilm-based infections.
Abstract: Biofilms are a protected niche for microorganisms, where they are safe from antibiotic treatment and can create a source of persistent infection. Using two clinically relevant Candida albicans biofilm models formed on bioprosthetic materials, we demonstrated that biofilm formation proceeds through three distinct developmental phases. These growth phases transform adherent blastospores to well-defined cellular communities encased in a polysaccharide matrix. Fluorescence and confocal scanning laser microscopy revealed that C. albicans biofilms have a highly heterogeneous architecture composed of cellular and noncellular elements. In both models, antifungal resistance of biofilm-grown cells increased in conjunction with biofilm formation. The expression of agglutinin-like (ALS) genes, which encode a family of proteins implicated in adhesion to host surfaces, was differentially regulated between planktonic and biofilm-grown cells. The ability of C. albicans to form biofilms contrasts sharply with that of Saccharomyces cerevisiae, which adhered to bioprosthetic surfaces but failed to form a mature biofilm. The studies described here form the basis for investigations into the molecular mechanisms of Candida biofilm biology and antifungal resistance and provide the means to design novel therapies for biofilm-based infections.

TL;DR: Human neuroblastoma cells transfected with constructs expressing wild-type beta APP or the beta APP717 mutants linked to familial Alzheimer's disease were compared and it was demonstrated that the 4-kilodalton A beta released from wild- type beta APP is primarily but not exclusively A beta 1-40.
Abstract: Normal processing of the amyloid beta protein precursor (beta APP) results in secretion of a soluble 4-kilodalton protein essentially identical to the amyloid beta protein (A beta) that forms insoluble fibrillar deposits in Alzheimer's disease. Human neuroblastoma (M17) cells transfected with constructs expressing wild-type beta APP or the beta APP717 mutants linked to familial Alzheimer's disease were compared by (i) isolation of metabolically labeled 4-kilodalton A beta from conditioned medium, digestion with cyanogen bromide, and analysis of the carboxyl-terminal peptides released, or (ii) analysis of the A beta in conditioned medium with sandwich enzyme-linked immunosorbent assays that discriminate A beta 1-40 from the longer A beta 1-42. Both methods demonstrated that the 4-kilodalton A beta released from wild-type beta APP is primarily but not exclusively A beta 1-40. The beta APP717 mutations, which are located three residues carboxyl to A beta 43, consistently caused a 1.5- to 1.9-fold increase in the percentage of longer A beta generated. Long A beta (for example, A beta 1-42) forms insoluble amyloid fibrils more rapidly than A beta 1-40. Thus, the beta APP717 mutants may cause Alzheimer's disease because they secrete increased amounts of long A beta, thereby fostering amyloid deposition.

TL;DR: The use of population doubling potential as a measure of biological age suggests that MSCs are intermediately between embryonic and adult tissues, and as such, may provide an in situ source for mesenchymal progenitor cells throughout an adult's lifetime.
Abstract: Recent studies have demonstrated the existence of a subset of cells in human bone marrow capable of differentiating along multiple mesenchymal lineages. Not only do these mesenchymal stem cells (MSCs) possess multilineage developmental potential, but they may be cultured ex vivo for many passages without overt expression of a differentiated phenotype. The goals of the current study were to determine the growth kinetics, self-renewing capacity and the osteogenic potential of purified MSCs during extensive subcultivation and following cryopreservation. Primary cultures of MSCs were established from normal iliac crest bone marrow aspirates, an aliquot was cryopreserved and thawed, and then both frozen and unfrozen populations were subcultivated in parallel for as many as 15 passages. Cells derived from each passage were assayed for their kinetics of growth and their osteogenic potential in response to an osteoinductive medium containing dexamethasone. Spindle-shaped human MSCs in primary culture exhibit a lag phase of growth, followed by a log phase, finally resulting in a growth plateau state. Passaged cultures proceed through the same stages, however, the rate of growth in log phase and the final number of cells after a fixed period in culture diminishes as a function of continued passaging. The average number of population doublings for marrow-derived adult human MSCs was determined to be 38 +/- 4, at which time the cells finally became very broad and flattened before degenerating. The osteogenic potential of cells was conserved throughout every passage as evidenced by the significant increase in APase activity and formation of mineralized nodular aggregates. Furthermore, the process of cryopreserving and thawing the cells had no effect on either their growth or osteogenic differentiation. Importantly, these studies demonstrate that replicative senescence of MSCs is not a state of terminal differentiation since these cells remain capable of progressing through the osteogenic lineage. The use of population doubling potential as a measure of biological age suggests that MSCs are intermediately between embryonic and adult tissues, and as such, may provide an in situ source for mesenchymal progenitor cells throughout an adult's lifetime.
