摘要:
The present invention relates to a method for inhibiting the induction of cell death by inhibiting the synthesis or secretion of AGE-albumin in cells of the mononuclear phagocyte system, to an AGE-albumin synthesis inhibitor, and to a pharmaceutical composition comprising the AGE-albumin synthesis inhibitor for preventing or treating degenerative disease and autoimmune disease. The AGE-albumin of the present invention is synthesized and secreted in human microglia or human macrophages in an Alzheimer's model, stroke model, Parkinson's disease model and rheumatoid arthritis model. The AGE-albumin synthesis and secretion are caused by oxidative stress. The expression of RAGE increases in first-order human neurons or cartilage cells to which AGE-albumin is administered, whereupon a MAPK signaling pathway is activated and the expression of Bax increases to induce an increase in calcium in mitochondria, thus finally inducing cell death. Therefore, the AGE-albumin synthesis inhibitor of the present invention can be valuably used in the diagnosis or treatment of degenerative diseases or autoimmune diseases such as Alzheimer's disease, strokes, Parkinson's disease, amyotrophic lateral sclerosis, rheumatoid arthritis, diabetic retinopathy, AIDS, aging, pulmonary fibrosis, spinal cord injuries, etc.

An image forming apparatus and a fusing unit thereof. The image forming apparatus includes a photosensitive body on which to form an electrostatic latent image, an exposure device to irradiate light to the photosensitive body to form the electrostatic latent image, a developer adhering device to adhere a developer to the photosensitive body on which the electrostatic latent image has been formed to form a visible image, a transfer device to transfer the visible image formed on the photosensitive body onto a printing medium, and a fusing unit to fuse the visible image transferred onto the printing medium to the printing medium. The fusing unit includes a press roller, a heating belt to closely contact the press roller to form a fusing nip to apply heat and pressure to the printing medium onto which the visible image has been transferred, first and second support rollers disposed apart from each other to circulatingly support the heating belt, and an elastic support device to elastically bias the first support roller and/or the second support roller in a direction away from each other to maintain a constant tension of the heating belt.

A sheet separating apparatus for a fusing unit separates a sheet being conveyed through a fusing unit from a heating roller and guides the sheet to a discharging roller without causing damages to a surface of a fusing roller. The sheet separating apparatus comprises a separating claw rotatably disposed toward a discharging side of a heating roller, for separating a sheet from the heating roller, and a contact spring pivoting the separating claw so that a front end of the separating claw is in contact with the heating roller with a predetermined constant pressure. The front end of the separating claw has rounded corners. It is preferred that the front end of the separating claw is chamfered. Also, it is preferred that the separating claw is made of stainless steel.

The present invention relates to a method for diagnosing glioma by comparing the protein location of an individual to be diagnosed with the normal control nerve cells. More particularly, the present invention relates to a method for diagnosing glioma including determining that an individual has glioma when the expression level of GFRα4 in the endoplasmic reticulum is higher than that in the plasma membrane, and a method for screening a therapeutic agent for glioma. In the diagnostic method of the present invention, the protein expression levels in particular subcellular locations are compared, thereby accurately diagnosing glioma, diagnosing progression of glioma, and predicting prognosis after glioma surgery.
摘要:
A fusing apparatus to fuse a toner image transferred to a printing medium by applying heat and pressure. The fusing apparatus includes a separation member that is rotatably mounted on a rotation axis to separate the printing medium from one of a heating roller and a pressing roller. The separation member includes a hollow portion into which the rotation axis is inserted, and a separation portion that contacts an outer circumference of the heating roller. The separation member is installed so as to be pitched around the rotation axis and a pitching axis having an inclination angle within a range of ±10° with respect to a line that connects a contact point between the separation portion and the outer circumference of the roller from which the printing medium is to be separated and a center of the roller from which the printing medium is to be separated.
