-
(2013-02-04)The cell’s nuclear envelope (NE) has pores that are stabilized by nuclear pore complexes (NPC), large proteinaceous structures whose function is to mediate transport between the nucleus and cytoplasm. Although the transport ...
-
(2017-04-24)The endoplasmic reticulum (ER) in Arabidopsis thaliana is the source of the calcium signal produced by high-fluence blue light sensed by the junction between the ER and chloroplast, the ER-chloroplast nexus. Photostimulation ...
-
The development of protein tags that enable the analysis of proteins with high multiplexity, in the context of cellular interactions. Nanoparticle and metal chelated tags were developed and utilized by Secondary Ion Mass ...
-
(1983)A new in vitro test for susceptibility to induced chromosomal damage is described. It involves treating primary fibroblast cultures with a known clastogen, bleomycin. The test differs from those previously published in ...
-
(2014-01-17)Diesel exhaust particulate matter (DPM) is a major contributor to air pollution and has been recently classified as a group 1 human carcinogen. The combustion of diesel produces a variety of compounds including polycyclic ...
-
(1982)The research reported in this thesis demonstrates that the initial steps for pyrimidine biosynthesis in the cellular slime mold Dictyostelium discoideum are catalyzed by the enzymes carbamoyl phosphate synthetase (CPSase, ...
-
(2019-04-18)Olive ridley sea turtles (Lepidochelys olivacea) are a vulnerable species. During their reproductive season these turtles migrate great distances to mate and lay eggs. Poor nutrition before this migration can result in ...
-
(2012-07-11)Vocal learning is the complex process by which an organism is able to modify its vocal output, such as birdsong or human speech, due to experience. The pathways used in the production and modification of human speech and ...
-
Migration is a behavioral syndrome that integrates morphological, behavioral and physiological traits. This syndrome exhibits considerable variation within and between species. This variation in migratory behavior has been ...
-
(2017-04-27)Six effector proteins of Salmonella enterica serovar Typhimurium - SseC, SseG, SseI, SseK1, SteB, and SopD - were studied in order to determine their molecular contributions to virulence. Data collected from a high-throughput ...
-
(2013-02-04)Clostridium difficile is a Gram-positive, anaerobic, spore-forming bacteria that is the leading cause of antibiotic-associated diarrhea. C. difficile infections (CDI) are thought to be caused by ingestion of spores by a ...
-
(2013-09-25)Microscopic organisms play an important role in carbon cycling in the ocean. Because of their large role, understanding how their activity is affected by other organisms and by particles in the water is important to ...
-
(2011-05-04)To study the effect of hyperosmolarity on the dynamic morphology of the endoplasmic reticulum (ER) form change, Nicotiana benthamiana seedlings with ER-labeled GFP-HDEL were put in a culture chamber and gradually infused ...
-
(1977)A key point in the regulation of pyrimidine biosynthesis by prokaryotic organisms is the enzyme Aspartate Transcarbamylase. This enzyme catalyzes the reaction of carbamyl phosphate plus aspartate to yield carbamyl aspartate, ...
-
(2012-04-26)Protein kinases are enzymes which phosphorylate other proteins and often play critical regulatory roles in cellular metabolism. We studied the effects of deletion of the TDA1 gene in Saccharomyces cerevisiae. TDA1 encodes ...
-
(1979)Microfilaria of Dirofilaria immitis from two heavily infected dogs were detected and measured using the Modified Knott's technique and the Difil Filter testᵃ. Variations in the procedures of the two tests were compared as ...
-
Effects of Experience and Meaningfulness on Learning and Memory in a Sensory Restricted Environment (1984)This study examines two previously untested conditions in a sensory restricted environment: meaningfulness and experience. Meaningfulness was measured by employing three different levels of learning material. The learning ...
-
(2021-04-28)Spinal cord injury (SCI) is an extremely devastating injury that can result in complete loss of all motor and sensory functions. Numerous studies have shown transplantation of neural progenitor cells (NPCs) has great promise ...
-
(1982)Juvenile hormone (JH), a sesquiterpene compound, acts as a morphogenetic hormone in insects; JH permits expression of the larval genome and inhibits expression of the adult genome. Previous experiments have indicated that ...
-
(2019-04-25)Feather damaging behavior, the intentional removal of feathers without the biological need to do so (i.e. lining a nest, breeding display, preening), is a complex syndrome frequently seen in captive parrots. Feather damaging ...
