Deep Brain

Deep brain stimulation (DBS) is now a widely accepted treatment option for patients with movement disorders such as parkinsonism and essential tremor. DBS surgery presents challenges to the anesthesiologist as often these patients are required to be awake for accurate placement of the stimulators. Additionally, patients with movement disorders often have comorbidities that increase their risk of perioperative and postoperative complications. DBS surgery is often divided into two stages (1) stereotactic implantation of the DBS leads and (2) internalization of the pulse generator, with each of these stages stage having distinct anesthesia demands. Ongoing studies are exploring other indications for the effective use of DBS surgery.

Cell Line Generation

B-lymphocytes normally synthesize small amounts of immunoglobulin, some of which is incorporated into the cell membrane where it serves as receptor of antigen. These cells, on contact with specific antigen, proliferate and differentiate to plasma cells which synthesize and secrete large quantities of immunoglobulin. The two stages of differentiation of this cell line (generation of B-lymphocytes and antigen-driven maturation to plasma cells) are clearly separable during ontogeny and in some immune deficiency diseases. The present report describes morphologic aberrations of B-lymphocytes in two diseases in which second stage differentiation is defective.

Polycrystalline Molybdenum

The evolution of dislocation channels in irradiated metals during deformation can be envisaged to occur in three stages: (i) formation of embryonic cluster free regions, (ii) growth of these regions into microscopically observable channels and (iii) termination of their growth due to the accumulation of dislocation damage. The first two stages are particularly intriguing, and we have attempted to follow the early stages of channel formation in polycrystalline molybdenum, irradiated to 5×1019 n. cm−2 (E > 1 Mev) at the reactor ambient temperature (∼ 60°C), using transmission electron microscopy. The irradiated samples were strained, at room temperature, up to the macroscopic yield point.Figure 1 illustrates the early stages of channel formation. The observations suggest that the cluster free regions, such as A, B and C, form in isolated packets, which could subsequently link-up to evolve a channel.
