atherosclerosis is the most common cause of myocardial infarction and ischemic stroke. various risk factors have been identified for atherosclerosis. recently, bacterial and viral organisms, which are involved in chronic inflammatory processes, have been also implicated in atherosclerosis development. individuals with a prior history of periodontal diseases and/or tooth loss are considered to be...

A 3D tomographic reconstruction algorithm for an absorptive perturbation in tissue is derived. The input consists of multiple 2D projected views of tissue that is back-illuminated with diffuse photon density waves (DPDWs). The algorithm is based on a generalization of the Projection-Slice Theorem and consists of depth estimation, image deconvolution, filtering, and backprojection. The formalism...

Our purpose is to report a case of diffuse unilateral subacute neuroretinitis (DUSN) in which an ophthalmoscopically visible worm was found and optical coherence tomography (OCT) scans allowed the precise localization of the parasite in the intraretinal layers. Our findings suggest that the parasite moves in the inner portions of the retina possibly explaining the severe degenerative neural cha...

Traumatic brain injury (TBI) is a leading cause of mortality and morbidity in Americans, especially those under age 45. TBI accounts for more than 500,000 emergency department visits annually (Nirula et al., 2003). Closed head injury produces cerebral edema, hemorrhage, contusions, and ischemia. Diffuse axonal injury (DAI) is also a common consequence of head trauma, and results from rotational...

Diffuse unilateral subacute neuroretinitis (DUSN) is a form of uveitis that can potentially lead to blindness. In Brazil and other parts of South America, diffuse unilateral subacute neuroretinitis is an important cause of posterior uveitis in children and healthy young adults. If diagnosed and treated in early stage, allows a resolution of symptoms with improvement of visual acuity. If the dis...

The present work describes the biological activities using the marine sponges collected from kanyakumari. The sponges are such as the Callyspongia diffusa, Echinodictyum gorgonoides, Callyspongia reticutis, Gelliodes cellaria, and Thalysias vulpine. It is revealed that the sponges showed the antifungal activity against the various fungal strains such as the Aspergillus niger, Pencillium notatum...

Spectra of objects which lie along several lines of sight through the diffuse interstellar medium (DISM) reveal an absorption feature near 3.4 micrometers, which has been attributed to saturated aliphatic hydrocarbons on interstellar grains. The similarity of the absorption bands near 3.4 micrometers (2950 cm-1) along different lines of sight indicates that the carrier of this band lies in the ...

BACKGROUND We describe a case of intraoperative fracture of phacoemulsification sleeve during phacoemulsification surgery. CASE PRESENTATION Phacoemulsification surgery was performed in the left eye of a 58-year-old lady with grade II nuclear sclerosis & grade I cortical cataract. Towards the end of quadrant removal, there was anterior chamber instability with impaired followability of nuclea...

Diffuse optical imaging is highly versatile and has a very broad range of applications in biology and medicine. It covers diffuse optical tomography, fluorescence diffuse optical tomography, bioluminescence, and a number of other new imaging methods. These methods of diffuse optical imaging have diversified instrument configurations but share the same core physical principle - light propagation...

A new and sensitive set-up to swiftly test proposed carriers of the diffuse interstellar bands (DIBs), over a relatively broad spectral range, is described. The instrument utilizes broadband cavity enhanced absorption spectroscopy (BBCEAS) and incorporates an optomechanical shutter to modulate light from a continuous incoherent light source. A pulsed supersonically expanding planar plasma expan...
