Sorption and vapor transmission properties of uncompressed and compressed microcellular starch foam.

Microcellular starch foams (MCFs) are made by a solvent-exchange process and consist of a porous matrix with pores generally ranging from approximately 2 microm to submicrometer size. MCF may potentially be useful as a slow-release agent for volatile compounds because of its ability to sorb chemicals from the atmosphere and to absorb liquids into its porous structure, and because it can be compressed to form a starch plastic. MCF made of high-amylose corn and wheat starches was prepared with or without 2% (w/w) silicone oil (SO) or palmitic acid (PA).

Treatment and biomechanical assessment of patients with chronic sacroiliac joint syndrome.

Objective: To evaluate diagnostic and biomechanical correlates and treatment outcomes of manipulative/adjustive care in patients highly selected for sacroiliac joint syndrome (SIJS).

Design: Descriptive case series, 1 wk baseline, 1 yr follow-up.

Setting: Private chiropractic practice.

Proliferation of cultivated cells from normal, preneoplastic and neoplastic human breast tissue--preliminary report.

The success of cultivation of epithelial cells from normal, neoplastic and preneoplastic tissues is reviewed. MCDB 170 medium with special supplements is useful for epithelial cell culture. The epithelial character was demonstrated by the reaction with 3 different monoclonal antibodies.

Response of different mammary epithelial cell lines to a mammary derived growth inhibitor (MDGI).

MDGI, a 14.5-KDa protein, is a chemically defined growth inhibitor, which we have purified from lactating bovine mammary gland and characterized biologically in a mouse Ehrlich ascites mammary tumour (EAT) short term suspension culture. It has now been tested for its inhibitory activity on proliferation of four malignant mammary epithelial cell lines of human and mouse origin and normal human mammary epithelial cells.

Secretion of phosphoproteins associated with neoplastic transformation and with the action of transforming growth factors.

Incubation of conditioned media derived from mammary epithelial cells and from fibroblasts with [gamma-32P]ATP revealed much higher intensities of labeled polypeptides in transformed cells compared to normal cells. Conditioned media from human mammary carcinoma cells have in common the presence of characteristic phosphoproteins with molecular masses of about 37,22 and 19.5 kDa.
