A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises insoluble amorphous sulfur extracted with zinc dithiocarbamate catalyst at 20° C. to form sulfur chain and transported to interior of synthetic polyisoprene particle forming physical attachment of sulfur to active sites. The degree of pre-vulcanization is verified by expansion of cast and dried film of latex in toluene in 20 minutes by means of a swelling index test. The latex emulsion is vulcanized at 90° C. to 120° C. for 3 to 5 minutes. Post-vulcanization composition with accelerators crosslink between synthetic polyisoprene particles, uniformly curing both in the inter-particle and intra-particle regions to produce high cross link density, uniform distribution of double bonds with zinc segregation at the boundaries of original particles. The condom exhibits high tensile strength, tensile modulus, elongation with excellent tear strength releasing below 10 ppb of nitrosamines.

A shoe cover is a natural latex article with reduced amount of sulfur cross linking agent and accelerators including zinc dithiocarbamate that break catalytically soluble sulfur Ssulfur rings forming sulfur linear chains. Surfactants present in the pre-vulcanization composition wets natural polyisoprene particles and permeates small sized sulfur into the interior of these particles thereby pre-vulcanizing the particles. The latex emulsion also has post-vulcanization composition with accelerators that crosslink between particles during the post vulcanization cure cycle. The dipped natural polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds and zinc segregation at the boundaries or original particles. The natural rubber films exhibit high tensile strength, tensile modulus, tear strength, elongation with low modulus of the shoe cover. The bottom surface of the shoe cover is etched to produce a slip resistant surface.

The hunger minimized fasting system relies on providing a blood glucose level at all times in the range of 5 to 10 mM, satisfying glucose needs of the brain and metabolizing blood glucose through anaerobic glycolysis to release ATP at the extramitocontrial portion of the cell. Consuming only solid free nutrient liquids eliminates brain hunger response. Liquids consumed during fasting include solid filtered vegetable soup and clear fruit juices of 8 to 12 ounces taken every 2 to 4 hours having calorie deficiency of 600 to 1400 as compared to minimal daily calorie requirements for an adult. Fat released from storage is metabolized by ATP produced by glycolysis at the extramitocontrial location and enters the interior of the mitochondria, enabling the TCA cycle. Weight loss observed during fasting is about one half to one pound per day.
