Engineering Deletions in the Mg1-Pk1 Gene Cluster of Streptomyces sp. Mg1 to Abolish Production of the Mg1-Pk1 Metabolite
(2013-09-25)
Many species of bacteria produce secondary metabolites in response to competitor species and changes to their local environment. Streptomyces sp. Mg1 (S. Mg1) produces the polyketide metabolite Mg1-Pk1, which participates ...
THE EFFECTS OF DIFFERENT ESTRADIOL DELIVERY METHODS ON PLASMA ESTRADIOL LEVELS IN MICE
(2013-12-16)
Evidence suggests that estrogen plays a role in decreasing the risk of developing colon cancer. Numerous animal studies demonstrate possible mechanisms to explain how estradiol (E2) prevents this disease. Many of these ...
Uterine Biology of the Pig: Gene Expression for Establishment of Pregnancy
(2013-09-25)
Pigs have considerable economic benefits so the death of 20 to 40 percent of their embryos during pregnancy represents a major economic loss [1]. Therefore, identifying the expression of key genes associated with embryonic ...
An Explanation for Beta's Mean-reversion
(2013-09-26)
This study aims to improve upon the CAPM by showing that the beta risk value of a stock is mean reverting and this mean reverting tendency is caused by firms' growth. Ninety stocks categorized into three sets (small ...
The effects of perinatal cadmium exposure on behavioral sensitization to morphine
(Texas A&M University, 2013-02-22)
This study examined the effects of developmental cadmium exposure on morphine-induced locomotor activity. Adult female rats were exposed to 0 ppm, 25 ppm and 50 ppm cadmium via an adulterated food source for 30 days prior ...
The development of a model of Alpha helix formation for transmembrane peptides
(Texas A&M University, 2013-02-22)
Researchers have studied the folding and binding properties of peptides in water for many years, but only recently has anyone attempted to explore those same tendencies in an environment similar to that of a transmembrane ...
Influence of nebulin on the assembly mechanics of desmin
(2013-09-19)
Desmin intermediate filaments (DIFs) bind to nebulin, forming a direct link between the intermediate filament (IF) cytoskeletal network and the Z-discs of myofibrils in muscle cells. As the main IF in muscles, desmin is ...
PDMSstar-PEG Hydrogels for Osteochondral Tissue Engineering
(2013-09-25)
Tissue engineering may utilize a “materials-guided” approach to repair of osteochondral defects (OCDs) – damage extending from cartilage to subchondral bone. Based on the physical and chemical properties of the scaffold ...
Autoimmune Diseases: Hemolytic Anemia
(2013-09-24)
Anemia is a term that defines a condition in which a person’s blood lacks a stable amount of red blood cells or hemoglobin. This condition can cause a person to experience fatigue, and an improper amount of oxygen will be ...
Optimal Motion Planning with constraints for mobile robot navigation
(Texas A&M University, 2013-02-22)
Motion planning is the process of planning a sequence of motions to move an object from one configuration to another. Recently, randomized techniques known as PRMs have shown great potential for solving motion planning ...
