In a recent series of papers, Kates (7-9) has presented a wealth of information in regard to the breakdown of lecithin by plant enzymes. A part of the work has been concerned with the degradation of phosphatidylcholine by carrot chromoplasts. The initial impetus to investigations concerned with phospholipide hydrolyzing plant enzymes which release free choline came from Hanahan and Chaikoff. Th...

PURPOSE This study assessed the impact of mandibular bone height on masticatory performance following treatment with a mandibular conventional denture (CD) or implant-retained overdenture (IOD). MATERIALS AND METHODS Evaluation of masticatory performance in 63 participants was made with original CDs and 6 months after treatment completion with new dentures; 25 patients received a mandibular C...

A total of 417 lung cancer cases and 849 controls were interviewed on their life-long tobacco usage and their current intake of four food items rich in retinol or carotene. The study was a hospital-based case control where 'cases' were lung cancer patients diagnosed during the period 1979/80 at seven hospitals in the Lombardy region (90% pathologically confirmed) and controls were patients admi...

Quantitative major polyacetylenes of carrots (falcarinol and falcarindiol) and American ginseng roots (falcarinol and panaxydol) were isolated and tested in human intestinal epithelial cells of normal (FHs 74 Int.) and cancer (Caco-2) origin. A hormesis effect was seen for all isolated polyacetylenes when added to Caco-2 cells in concentrations ranging from 1 ng/mL to 20 microg/mL. The relative...

The influences of barrier properties of packaging materials and storage conditions on selected quality attributes of carrot samples processed by pressure-assisted thermal processing (PATP) were investigated. Baby carrots were packaged in three different pouches made of multilayer films (Nylon/EVOH/EVA, Nylon/EVA and MetPET/PE) and processed at 600 MPa and 110 °C for 10 minutes. Processed pouche...

I present a model of corruption with incomplete information where the bureaucrat may request bribe from citizen for providing service. show that is detrimental to social welfare and consider new policy prevent it. propose punishing bureaucrats who take bribes rewarding citizens report such cases. Neither punishment nor rewards can alone. However, proper combination completely prevents corruptio...

Investigations were carried out to study the effects of selected blanching treatments on the quality of carrots over a temperature range of 80–100C. The blanching treatments selected were steam, water, 0.05 N acetic acid solution and 0.2% calcium chloride solution. These blanching treatments were evaluated with respect to the inactivation time of peroxidase (POD) and catalase, and the process w...

ated state of tissues and particularly the skin, it has Health Food become increasingly valuable in the treatment of more than 100 dermatological disorders and of various cancers. Probably the most well known of its uses is in the Vitamin A and Retinoids: An Update of Biological treatment of acute promyelocytic leukemia, where RA Aspects and Clinical Applications induces complete remission rate...
