Compositional differences between infant and adult human corneal basement membranes. (1/17)

PURPOSE: Adult human corneal epithelial basement membrane (EBM) and Descemet's membrane (DM) components exhibit heterogeneous distribution. The purpose of the study was to identify changes of these components during postnatal corneal development. METHODS: Thirty healthy adult corneas and 10 corneas from 12-day- to 3-year-old children were studied by immunofluorescence with antibodies against BM components. RESULTS: Type IV collagen composition of infant corneal central EBM over Bowman's layer changed from alpha1-alpha2 to alpha3-alpha4 chains after 3 years of life; in the adult, alpha1-alpha2 chains were retained only in the limbal BM. Laminin alpha2 and beta2 chains were present in the adult limbal BM where epithelial stem cells are located. By 3 years of age, beta2 chain appeared in the limbal BM. In all corneas, limbal BM contained laminin gamma3 chain. In the infant DM, type IV collagen alpha1-alpha6 chains, perlecan, nidogen-1, nidogen-2, and netrin-4 were found on both faces, but they remained only on the endothelial face of the adult DM. The stromal face of the infant but not the adult DM was positive for tenascin-C, fibrillin-1, SPARC, and laminin-332. Type VIII collagen shifted from the endothelial face of infant DM to its stromal face in the adult. Matrilin-4 largely disappeared after the age of 3 years. CONCLUSIONS: The distribution of laminin gamma3 chain, nidogen-2, netrin-4, matrilin-2, and matrilin-4 is described in the cornea for the first time. The observed differences between adult and infant corneal BMs may relate to changes in their mechanical strength, corneal cell adhesion and differentiation in the process of postnatal corneal maturation.  (+info)

A novel phenotype-genotype relationship with a TGFBI exon 14 mutation in a pedigree with a unique corneal dystrophy of Bowman's layer. (2/17)

PURPOSE: Corneal dystrophy of Bowman's layer (CDB) belongs to a group of dystrophies associated with mutations in the transforming growth factor-beta-induced (TGFBI) gene. CDB is further divided into a geographic variant (CDB1/Reis Bucklers, RBCD), and a honeycomb variant (CDB2/Thiel Behnke, TBCD). We undertook mutational analysis of TGFBI in a family with an unusual CDB variant and describe a novel phenotype-genotype association. METHODS: Individuals from a pedigree with CDB underwent extensive phenotyping, including laser scanning in vivo confocal microscopy, and histological examination of four corneal buttons obtained at penetrating keratoplasty. Transmission electron microscopy of an excised allograft cornea from one affected individual was also performed. Following informed consent, DNA samples were collected. Polymerase chain reaction (PCR) and sequencing of all coding exons of TGFBI was performed. Family members were recruited with subsequent phenotyping and genotyping, and paternity testing. RESULTS: Clinical examination and other phenotypic information confirmed a diagnosis of CDB, with various features either more suggestive of CDB1 or of CDB2. A mutation in exon 14, H626P, segregated with the disease in this pedigree. This mutation was confirmed with NlaIII restriction enzyme digest, and was not seen in 100 control chromosomes. CONCLUSIONS: Within this pedigree, CDB segregates with an H626P mutation, which is previously described occurring in lattice corneal dystrophy. The majority of mutations in TGFBI previously described segregating with CDB1 and CDB2 are R124L and R555Q, respectively. Although a Bowman's layer dystrophy, the phenotype in this pedigree does not closely conform to the classical diagnostic criteria for either CDB1 or CDB2, and therefore represents a novel phenotype-genotype correlation.  (+info)

In vivo observation of Langerhans cells by laser confocal microscopy in Thygeson's superficial punctate keratitis. (4/17)

PURPOSE: To characterize the cornea of individuals with Thygeson's superficial punctate keratitis (TSPK) at the cellular level by laser confocal biomicroscopy. METHODS: Both corneas of three patients with TSPK referred to Yamaguchi University Hospital were imaged with a laser confocal biomicroscope. Morphological changes were evaluated for each layer of the cornea. RESULTS: The number of Langerhans cells was greatly increased in the basal cell layer of the focal corneal epithelium and in Bowman's layer in the four eyes affected by TSPK. Aggregates of these cells were associated with the subepithelial nerve plexus. Langerhans cells were also evident in the unaffected eyes of the two patients with unilateral TSPK, although their numbers were much smaller than those in the affected eyes. Topical treatment with betamethasone phosphate resulted in the virtual disappearance of Langerhans cells from the affected eyes. CONCLUSION: The prominent association of Langerhans cells with TSPK suggests that the activation of these cells by inflammatory conditions might contribute to the pathogenesis of this disorder.  (+info)

Purpose.: To investigate the ultrastructure of advanced Salzmann nodular degeneration (SND) and to correlate it to confocal in vivo findings. Methods.: The corneal degenerative nodules from four patients with SND were examined with confocal microscopy and then removed and processed for light microscopy (LM) and transmission electron microscopy (TEM). Results.: The confocal examination revealed elongated basal epithelial cells and activated keratocytes in the anterior stroma near the nodules. Occasional subbasal nerves and tortuous stromal nerve bundles were observed. With LM and TEM, five zones were described: one internodular and four pertaining the nodule, each characterized by peculiar aspects of the epithelium and stroma. As also confirmed by the morphometry, in the zones corresponding to the nodules, the epithelium was lower and with fewer cell layers than the peripheral zones. Over the nodules, the basement membrane was discontinuous or absent and the Bowmans layer, when present, had a ...
The Bowmans membrane (Bowmans layer, anterior limiting lamina, anterior elastic lamina) is a smooth layer in the eye. It is located between the front epithelium and the stroma in the cornea. It is composed of strong collagen fibers and helps the cornea maintain its shape. If the Bowmans membrane is damaged, scarring would normally occur. In adult humans, this layer is 8-12 μm thick.[1] Bowmans layer is absent in cats, dogs, and other carnivores.[2] The Bowmans membrane is named after Sir William Bowman (1816 - 1892), an English physician, anatomist and ophthalmologist, who discovered this membrane. ...

Several methodological limitations became evident during the course of this study. It was noted that IVCM imaging of BL can be difficult due to patient and operator-induced motion artifacts, and an experienced operator performing multiple volume scans through BL is necessary to obtain quality image stacks for analysis. Also, as noted earlier, initial use of the section scan method in transplant patients precluded direct comparison of Method 2 thickness values with LM in the same corneas. Another limitation is the axial resolution of laser-scanning IVCM, which, at 4 μm presently, is almost half the thickness of BL in sections. To better locate the borders of BL, a finer axial resolution is required, combined with a finer axial spacing of adjacent confocal images. Also, as observed in LM sections in this study not included in the analysis, BL thickness may not be constant over the entire central cornea, particularly in pathologic cases. The assumption of constant BL thickness in the central ...

The present invention provides method of adjusting a thickness profile of a top metal layer of a workpiece using a processing solution. A thickness profile control member is included that has at least first and second regions that will allow for processing at respective first and second rates that are different from each other. When processing the workpiece, the processing system establishes relative lateral movement between the workpiece and the thickness profile control member so that a certain portion of the workpiece is disposed in locations that correspond to the first and second regions at different points in time during the processing. In a preferred aspect, the lateral movement is controlled as a result of data obtained from sensors relating to the thickness of a removed or deposited layer.

With the use of HRTII-RCM, we have obtained in vivo images of the central cornea in eyes affected by TSPK. Although dendritic cells were observed in the unaffected healthy corneas of the two patients with unilateral TSPK, these cells were greatly increased in number and formed aggregates in both the basal cell layer of the corneal epithelium and in Bowmans layer of the affected eyes. The dendritic cells in Bowmans layer appeared associated with the nerve fibers that form the nerve plexus of the corneal epithelium. Medical intervention reduced the numbers of these dendritic cells to normal values. With use of HRTII-RCM, we were able to observe abnormalities of cell shape and cell density in the eyes affected by TSPK. In the affected eyes, accumulation of dendritic cells was apparent in the focal lesions. Tandem scanning confocal microscopy of eyes affected by TSPK previously revealed multiple highly reflective filamentous structures in Bowmans layer of the corneal epithelium, but these ...

switch-pumped supercontinuum (QS-SC) source, operating in the kilohertz regime, for ultra-high resolution optical coherence tomography (UHR-OCT) in the 1300 nm region. The QS-SC source proves to be more intrinsically stable from pulse to pulse than a mode-locked-based SC (ML-SC) source while, at the same time, is less expensive. However, its pumping rate is lower than that used in ML-SC sources. Therefore, we investigate here specific conditions to make such a source usable for OCT. We compare images acquired with the QS-SC source and with a current state-of-the-art SC source used for imaging. We show that comparable visual contrast obtained with the two technologies is achievable by increasing the readout time of the camera to include a sufficient number of QS-SC pulses.. © 2017 Optical Society of America.

Karl Murdock Bowman, MD (November 4, 1888 - March 2, 1973) was a pioneer in the study of psychiatry. From 1944 to 1946 he was the president of the American Psychiatric Association. His work in alcoholism, schizophrenia, and homosexuality is particularly often cited. Bowman was born in Topeka, Kansas, and graduated from Washburn University. His nickname in college was Tommy, according to the schools 1910 yearbook. While at Washburn, he was a member and president of the Delta Phi Fraternity, forerunner of the Kansas Beta Chapter of Phi Delta Theta Fraternity. Bowman was initiated into Phi Delta Theta with the chapters founding fathers on October 1, 1910.

The author describes a BOWMAN layer graft FEMTO technique applied to different stages of keratoconus. The donor is prepared using the Femtosecond laser. In keratoconus, the graft button is a 360° disc, 60µm thick inserted in a FEMTO cut pocket. In pellucid marginal degeneration (PMD), the graft is an inferior crescent used to reinforce the lower ectatic zone. Results are briefly summarized ...
Bowmans Capsule and GlomerulusThe structure of the sac of the Bowmans capsule is thin which surrounds the Glomerulus. The glomerulus is composed of clustered together blood capillaries. The Bowmans capsule contains 2 layers. The interior layer that covers the Glomerulus while the exterior layer continues to layer the renal tube walls. Its main role of the Bowmans capsule is to filter out the wastes and other substances such as water and salts. The Glomerulus role is to create urine by filtering down the blood. This is then transported through the Bowmans capsule and then into the proximal convoluted tubules.http://www.innerbody.com/image_card08/card65-new.html#continuedProximal convoluted tubule:The Proximal convoluted tubule is located between the Bowmans capsule and the loop of henle. Its main function is to allow the glucose, water and other substances such as peptides and nutrients to flow back into the bloodstream from the tubule fluid. This happens because the ciliated cells which ...

A method and system for reshaping Bowmans membrane, which lies directly below the anterior epithelial surface of the cornea, to provide correction of refractive errors in the eye by photoablation of selective regions of the Bowmans membrane without substantial penetration into the stroma of the eye is disclosed including a laser and a beam-shaping mask, disposed between the laser and the surface of the cornea, which imposes a defined ablation profile upon the Bowmans membrane by laser radiation. The system can also include a feedback control for measuring the effectiveness of the laser during operation and for controlling the laser such that the reprofiling operation is substantially confined to the Bowmans membrane throughout the procedure. The beam-shaping mask can include either an aperture e.g., a beam-shaping stop means alone or in combination with a beam-shaping window, or an mask which is erodible or otherwise graded in its absorptive capacity to present a predefined profile of resistance to
A combined ultrahigh resolution optical coherence tomography (UHROCT) and a electroretinography (ERG) system is presented for simultaneous imaging of the retinal structure and physiological response to light stimulation in the rodent eye. The 1060-nm UHROCT system provides ~3×5 µm (axial×lateral) resolution in the rat retina and time resolution of 22 µs. A custom-designed light stimulator integrated into the UHROCT imaging probe provides light stimuli with user-selected color, duration, and intensity. The performance of the combined system is demonstrated in vivo in healthy rats, and in a rat model of drug-induced outer retinal degeneration. Experimental results show correlation between the observed structural and physiological changes in the healthy and degenerated retina ...

Freely available reference brain shows virtual human brain anatomy in fine detail. A landmark three-dimensional (3-D) digital reconstruction of a complete human brain, called the BigBrain, now for the first time shows the brain anatomy in microscopic detail-at a spatial resolution of 20 microns, smaller than the size of one fine strand of hair-exceeding that of existing reference brains presently in the public domain. The new tool is made freely available to the broader scientific community to advance the field of neuroscience.. Researchers from Germany and Canada, who collaborated on the ultra-high resolution brain model, present their work in the 21 June issue of the journal Science, which is published by AAAS, the international non-profit science society.. The authors pushed the limits of current technology, said Sciences senior editor Peter Stern about the international scientific effort. Such spatial resolution exceeds that of presently available reference brains by a factor of 50 in ...

Raw 100 is a video series designed to highlight the talent and creativity of filmmakers. If simplicity is the ultimate sophistication, then this series celebrates that idea.. The rules for each video are simple: 100 seconds in length, no slow motion footage and no music. By having to work within these limitations, filmmakers have to get creative and think outside the box.. For the making of this Raw 100 video, Moxley Cinema linked up with Noah Bowman in the dying days of last winter at Calgary Olympic Park. When it comes to style in the halfpipe, Bowman sits atop the throne. In the everyday arms race to have the biggest and baddest tricks in the stunt ditch, Bowman is the fluid reminder of Charles Bukowskis thinking that doing a dangerous thing with style is art. This 100 seconds will have you wanting more. ...
