Env’s transmembrane domain revealed HIV-1’s envelope protein (Env) spans the viral membrane and grants the virus entry into host cells. Env is also the sole protein of HIV-1 that is targeted by antibodies, making it a key target for vaccine design. Dev et al. used nuclear magnetic resonance to determine an atomic-level structure of the membrane-spanning region of Env in a lipid bicelle. Env’s t...

embryo undergoes several synchronized nuclear divisions without cytokinesis, to form a 'syncytial blastoderm'. During these divisions, the nuclei migrate to the cortex of the embryo where the last few divisions take place before cellularization. The dividing nuclei at lower right are all synchronized at metaphase. Mitotic spindles are stained red; DNA is stained green. At cellularization, the o...

study cultured stem cells from human embryos can proceed without violating the federal ban on embryo research in general. Since that decision, a great deal of excitement has arisen over the possibility that treatment of neurological disease may take a giant leap forward in the near future. The secrets to everything from preventing Alzheimer's Disease to reversing spinal cord damage may soon be ...

The implementation of a Structure-from-Motion (SfM) pipeline from a synthetically generated scene as well as the investigation of the faithfulness of diverse reconstructions is the subject of this project. A series of different SfM reconstructions are implemented and their camera pose estimations are being contrasted with their respective ground truth locations. Finally, injection of ground tru...

arginine (arg) requirements of male broilers (ross 308) reared at high altitude (2100 mabove sea level) during the 1-to 3-week period was estimated in a graded supplementationmethod, in which six diets (230 g kg-1 cp and 3200 kcal me kg-1) with arg increments of1.25 g kg-1 were applied to four pens of fifteen birds each. dietary arg content of theexperimental groups ranged from 10 g kg-1 (80% o...
