High anomalous origin of both coronary arteries is extremely rare. We report the case of a patient with a right coronary artery that originated from the left surface of the ascending aorta approximately 25 mm above the sinotubular junction and a left coronary artery that originated from the sinotubular junction close to the non-left commissure. The patient also had persistent left superior vena cava.

Methods: : Fourteen subjects were candidates for radical retropubic prostatectomy (RRP) and pelvic lymph node dissection (PLND). After an indocyanine green solution was injected into the prostate during RRP, lymphatic vessels draining from the prostate were analyzed using a FN system.
Invasive stage embryos of the parasitic wasp Copidosoma floridanum transmigrate through the epithelium of phylogenetically distant host embryos in a manner that is similar to mammalian leukocyte infiltration. Host embryonic cells appear to recognize the invading wasp embryo by components on the cell surface. We developed an in vitro wasp entry inhibition assay and found that C-type lectins of the wasp embryo bound to N-linked carbohydrate chains with fucose residues on the surface of host embryo.

The planned right donor nephrectomy was uneventful, with a warm ischemic time of 5 minutes, but her right renal vein was too fragile and weak to be repaired for vascular anastomosis. Therefore, we used an artificial vascular graft (polytetrafluoroethylene) interposed between the donor renal vein and the recipient's left external iliac vein.

Design: Prospective study, university hospital setting.
Participants: Twenty-six eyes with a macular hole, seven eyes with a macular hole retinal detachment and four eyes with a macular hole and myopic traction maculopathy underwent vitreous surgery.
Epidemiological studies have revealed that radiation causes brain development abnormalities in atomic bomb survivors exposed in utero. Rat and mouse studies have also shown that prenatal exposure to low-linear energy transfer radiation induces developmental brain anomalies. Because the effects of prenatal irradiation on adult behavior patterns remain largely unknown, the present study investigated the effects of neutron exposure in utero on postnatal behavior patterns in mice.

Methods: The effect of Av was studied in radiation-exposed rats compared with radiation-only and control rats.
Purpose: To investigate the influence of 2% carteolol long-acting solution (long-acting carteolol) and 0.5% timolol gel-forming solution (timolol gel) on ocular wavefront aberrations.
Methods: Ocular aberrations were assessed in the right eye of 24 healthy volunteers at baseline and at 2, 5, 10, and 15 min after instillation of long-acting carteolol, timolol gel or physiological saline using the Hartmann-Shack aberrometer.
Purpose: To measure ophthalmodynamometric pressure (ODP) during vitrectomy in patients with proliferative diabetic retinopathy (PDR).
Design: Prospective, interventional, consecutive case series.
Methods: This study included 75 eyes of 75 patients undergoing vitrectomy for PDR.

Purpose: This prospective study was conducted to assess the influence of overnight orthokeratology (OK) on axial elongation in children, with those wearing spectacles as controls.
Methods: One hundred five subjects (210 eyes) were enrolled in the study. The OK group comprised 45 patients (90 eyes, age 12.
Background: Klebsiella pneumoniae endophthalmitis is rare and despite immediate management, visual outcome is generally poor. We report a case of endogenous K. pneumoniae endophthalmitis that was treated successfully.

Background: To characterize the infrared (IR) and fundus autofluorescence (FAF) images of eyes with optic disc pit maculopathy.
Methods: A retrospective non-comparative study of three patients with optic disc pit maculopathy who were followed by optical coherence tomography (OCT) and retinal angiography (Heidelberg retina angiograph 2) before and after vitreous surgery without laser photocoagulation.
Results: The areas of serous retinal detachment and inner retinal schisis were dark in the IR and FAF images preoperatively; and they changed to brighter areas following reattachment of the retina.

A healthy 64-year-old man presented with a non-tender soft mass in the upper inner quadrant of the anterior left orbit. Magnetic resonance imaging revealed a 14 x 16 x 14-mm homogeneous cystic lesion in the anterior superonasal orbit with a distinct margin. An orbital cyst was suspected, and its surgical removal was planned.

Electron microscopic analyses of cellular interactions between the extraembryonic syncytium of the parasitic morula and the host embryonic epithelial cells showed that morula penetration into the host embryo did not cause obvious damage to the host cells, except for the abrasion of the embryonic cuticle. Epithelial cells of the host embryo extended microvilli toward the invading C.

Methods: This study included 169 eyes of 169 patients undergoing pars plana vitrectomy. After core vitrectomy, the intraocular pressure was gradually raised by using the VGFI system.

Although cytolysis of invading organisms is an innate form of immunity used by invertebrates, so far the underlying mechanism remains less explored. The pupal hemolymph of the mosquito Armigeres subalbatus induces an activity that causes hemolysis of human red blood cells (HRBC). This hemolytic activity was inhibited by sialic acid (N-acetylneuraminic acid) and serine protease inhibitors.

Recently, we have reported that oral administration of cystine and theanine (CT) to mice enhanced the humoral immune response associated with antibody production. Based on this mouse study, we investigated the effects of CT supplementation on the common cold in humans as a pilot study.

The 2D diffraction layer was fabricated by our original nanofabrication technique, the embedded particle monolayer method, which could form a self-assembled particle monolayer. As a result, the electroluminescence intensity of the device with the 2D diffraction layer was improved by 1.
