The Laws of Physics, Paradox, and Orderly Conduct in the Randomness Zone

submitted by: hsrikm
A conceptualization of the universe as nonrandom consistently with respect to a universal established from certain descriptive properties of space, but random with respect to all perspectives, is proposed as a outline for the interpretation of nature. This view enables the construction of a natural ethic in which many of the orderly conducts of science become exposed as inductive, falling short of being sound and valid, resulting in false interpretation that is potentially damaging in...

The Dynamic Bacterial Cell by Lucy Shapiro, April 2007 - Part 1: Dynamics of Bacterial Chromosome Organization, Segregation, and Cytokinesis (34:32)

submitted by: video_collector
Most bacterial cells have their genes arranged in a single circle of DNA. The circle of DNA plus some attached proteins is referred to as the bacterial chromosome. Up until quite recently, it was thought that the chromosome in the tiny bacteria cell resembled a tangled ball of yarn. It is now known that multiple factors cooperate to condense DNA into a highly dynamic assembly of supercoiled loops. Although there is variability in the lower levels of chromosome structure, the global...

XERODERMA PIGMENTOSUM

Hereditary disease, trasmitted with recessive autosomical modality, the XP is characterized from extreme photosensivity, that causes strict and premature damages to level of the cutis and of the eyes. Its incidence is of 1: 250 thousand in Europe and USA, while in Japan the relationship is of 1:40 thousand. In the child affected by XP, also short exposure to the sun's ultraviolet rays, determines severe cutaneous sunburn with slow resolution, therefore it is from avoiding sources of...

MITOCHONDRIAL DNA LAUNOIS-BENSAUDE's LIPOMATOSIS

submitted by: camdic
Even though Brodie is said to have first described diffuse symmetrical lipomatosis with predilection for the neck already in the 1846 (Clinical Lectures on Surgery, Delivered at St. George's Hospital Philadelphia: Lea and Blanchard pub. Pp 201-201. Brodie, B.C.) still unknown is today the pathogenesis of Launois Bensaude' Lipomatosis. Klopstock et Al. are found in muscle biopsy specimens ragged and red fibers, pathologic subsarcolemmal accumulations of mitochondria, suggesting a...
