Download Optical Coherence Tomography: A Clinical and Technical by Conceição Lobo, Isabel Pires, José Cunha-Vaz (auth.), Rui PDF

By Conceição Lobo, Isabel Pires, José Cunha-Vaz (auth.), Rui Bernardes, José Cunha-Vaz (eds.)

Optical Coherence Tomography represents the last word noninvasive ocular imaging method even supposing being within the box for over two-decades. This publication encompasses either clinical and technical advancements and up to date achievements. the following, the authors hide the sphere of program from the anterior to the posterior ocular segments (Part I) and current a complete evaluate at the improvement of OCT. vital advancements in the direction of scientific purposes are lined partially II, starting from the adaptive optics to the combination on a slit-lamp, and passing via new structural and practical info extraction from OCT information. The ebook is meant to be informative, coherent and accomplished for either the clinical and technical groups and goals at easing the verbal exchange among the 2 fields and bridging the space among the 2 clinical communities.

This publication is an updated evaluate of present wisdom within the box of a number of drug resistance in human melanoma. The literature as much as the center of 1993 is surveyed in expert chapters written through various specialists. subject matters coated comprise the molecular genetics, cytogenetics and biochemistry of the mdr genes and P-glycoprotein; substitute delivery proteins in MDR; topoisomerases I and II; cytochrome p450-enzymes and glutathione- S-transferases in MDR; mobile versions for MDR in sturdy tumours and haemopoietic tumours; immunochemical and molecular organic strategies for detection of MDR-related gene expression; and medical and pharmacological thoughts to bypass resistance.

Clinical Transplantation: Current Practice and Future Prospects

This quantity has been written in particular for the working towards clinician. All facets of medical transplantation have increased significantly in recent times, yet some of the medical professionals concerned have bought very little school in immunology as clinical scholars. a few of the chapters, written by means of physicians, surgeons, pathologists and immunologists current a number of the at present vital concerns in transplantation and exhibit uncomplicated venture of immunology is now crucial in lots of components of medical perform.

The nationwide Institute on getting older (NIA) has traditionally been thinking about the safety of human topics. In July 1977, the NIA backed a gathering to replace and complement consultant­ traces for safeguarding these engaging in Federal study professional­ jects. even supposing the elemental directions have been in impression for the reason that 1966, it were overlooked to incorporate the aged as a susceptible inhabitants.

Retinal opacification is more prominent in the posterior pole, becoming less apparent in the periphery. Yellowish white peripapillary area which represents axoplasmic material accumulation can be noticed (white arrows). (b) OCT shows increased reflectivity and diffuse mild thickening (edema) in the inner retinal area. “Prominent middle limiting membrane” is a hyperreflective line visible near the synaptic portion of outer plexiform layer (white triangles) in acute ischemic inner retinal area. The outer retina shows hyporeflective change, which is caused by shadowing from the abnormally hyperreflective inner retina.

5 Acute CRAO with cilioretinal artery sparing. 52-year-old male with CRAO with acute cilioretinal artery sparing. (a) In the early-phase fluorescein angiography, a large inferotemporal cilioretinal artery shows early-phase dye filling and subsequent dye filling in adjacent vein. Retrograde filling of an arteriole at the superior macula is noticed. (c–g) On OCT, increased reflectivity and mild thickening of the retina are noticed at nonperfused area. There is sharp demarcation between perfused area and nonperfused ischemic area.
