PURPOSE Human eyes with exfoliation syndrome (XFS) exhibit a distinctive pattern of iris transillumination defects that are recapitulated in Lyst mutant mice carrying the beige allele. The purpose of this study was to determine the anatomic basis for Lyst-mediated transillumination defects, test whether Lyst mutant mice develop other features of XFS, and describe the molecular basis of the beig...
Abstract Background Submucous cleft palate (SMCP) is a congenital abnormality with various clinical and anatomical features. pathologies may be unrecognized during routine examinations. Current diagnostic techniques are constrained unrevealing in presurgical patients. This prospective study aimed to evaluate transnasal palatal transillumination technique diagnosis of SMCP at our institute hospi...
BACKGROUND The present study aimed to compare the safety and efficacy for novices to conduct intubation with the Bonfils intubation fiberscope (BIF) using the transillumination-assisted or midline approach technique in patients with normal airways. METHODS In this prospective randomized control study, 10 trainees were assigned to the transillumination-assisted technique group (T group) or the...
Bladder endometriosis is uncommon yet a cause of cyclical disabling urinary symptoms. Surgical excision the bladder endometriotic nodule using combined cystoscopic and laparoscopic approach (“light to light technique”) remains best where surgery deemed mode treatment. A 31-year-old infertile woman underwent resection by this method. The main surgical steps included ureteric stenting, mobilizati...
RATIONALE Occult small bowel bleeding is always difficult to locate by either radiological examination or endoscopy. When the site of bleeding cannot be found by nonsurgical measures, exploratory laparotomy becomes necessary. PATIENT CONCERNS A 63-year-old woman with a half-month history of occult gastrointestinal bleeding failed to many conservative therapies. INTERVENTIONS Intraoperative ...
To realize three-dimensional (3D) optical imaging of the internal structure of an animal body, we have developed a new technique to reconstruct optical computed tomography (optical CT) images from two-dimensional (2D) transillumination images. In transillumination imaging of an animal body using near-infrared light, the image is blurred because of the strong scattering in the tissue. To overcom...
The structural pattern of the iris in 13 patients with Fuchs's heterochromic cyclitis (FHC) was studied by infra-red transillumination stereophotography. All eyes with FHC showed atrophic changes of the iris. Extensive iris atrophy appeared as light, even translucence of the iris, associated in some cases with occasional dense small patches or pigment clumps. Moderate punctate, patchy or radiat...
The composite insulator sheath plays an important role in protecting the core rod and insulation. thickness of must meet corresponding standard requirements. During manufacturing process, decentration leads to uneven sheath, which is easy cause risk insulators premature failure during operation. phased array detection technology can accurately detect so that defects such as (decentration rod) b...
L'albinisme regroupe un ensemble d'affections héréditaires liées à une anomalie de biosynthèse de la mélanine secondaire à un déficit variable en tyrosinase, enzyme impliquée dans la synthèse de ce pigment. La mélanine est élaborée dans des cellules spécialisées de la peau, des cheveux, de l'épithélium pigmenté de la rétine et au niveau de l'iris. L'examen à la lampe à fente d'un sujet albinos ...
