Openable artificial intestinal tract device integrated with a permeable filter for evaluating drug permeation through cells.

Organs-on-chips using cultured cells have been developed and applied for evaluating in vitro biological phenomena. We previously reported an openable artificial intestinal tract system, as an in vitro model of the small intestine, for in vitro drug screening. The intestinal tract device could be transformed using an integrated artificial muscle actuator.

A pediatric case with parvovirus B19-associated uveitis without autoantibody formation.

Acute parvovirus B19 (B19) infection is often accompanied by autoantibody formation, including antinuclear antibodies and rheumatoid factor, and the symptoms of the infection are similar to those of several autoimmune diseases. Uveitis is a representative manifestation of autoimmune diseases and is rarely caused by B19. Autoantibody formation was confirmed in 2 previously reported cases with B19-associated uveitis.

[Effect of Intravitreal Bevacizumab Injection on Iris and Iridocorneal Angle Neovascularization in Neovascular Glaucoma].

Neovascular glaucoma is a serious complication associated with retinal ischemic changes, which increase the production of vascular endothelial growth factor. Vascular endothelial growth factor has been implicated as a key molecule in the development of newly formed vessels and neovascular glaucoma. Intravitreal injection of bevacizumab, a full-length humanized anti-vascular endothelial growth factor monoclonal antibody, leads to a dramatic regression of the new iris and iridocorneal angle vessels on slitlamp examination.

Reconstruction of a nonfunctional trabeculectomy bleb using an amniotic membrane-wrapped silicone sponge to treat refractory glaucoma.

Background: This study was conducted to verify the usefulness of nonfunctional trabeculectomy bleb reconstruction using a silicone sponge wrapped with amniotic membrane. Its purpose was to allow aqueous humor to flow from the flap to the posterior orbital space.

Methods: Seven consecutive patients who had undergone two or more surgeries in one eye for refractory glaucoma followed by our operation were included in this study.

A classic temporal optic disc pit showing progression in the corresponding optic nerve fiber and visual field defects.

Purpose: We report a rare case with a classic temporal optic disc pit (ODP) showing the progression of an associated nerve fiber layer defect (NFLD) with the corresponding visual field defect (VFD).

Methods: We describe the patient's medical records and review the pertinent literature.

Results: A 54-year-old woman had a temporal ODP, which was considered to be congenital, associated with both NFLD expanded to both the upper and lower sides of the horizontal line and corresponding VFD and a small ODP-like excavation at the 6.

Angiographic changes in iris and iridocorneal angle neovascularization after intravitreal bevacizumab injection.

Objective: To evaluate the effects of the intravitreal (IV) injection of bevacizumab on anterior segment neovascularization using anterior segment angiography.

Methods: We observed 1 eye with iris and iridocorneal angle neovascularization and 3 with neovascular glaucoma from 4 patients with diabetic retinopathy in 3 eyes and central retinal vein occlusion in 1 eye. Two healthy eyes from 2 other patients served as control eyes.

Effect of latanoprost on the diurnal variations in the intraocular and ocular perfusion pressure in normal tension glaucoma.

Purpose: To evaluate the effects of latanoprost on the diurnal variations in the intraocular pressure (IOP) combined with the ocular perfusion pressure (OPP) in patients with normal tension glaucoma (NTG).

Patients And Methods: Twenty-two eyes from 22 patients with NTG were used for the study. The diurnal variations in the IOP and blood pressure (BP) were measured every 3 hours without therapy, and then the patients were treated with latanoprost (0.
