A 50-year-old man underwent abdominal rectopexy with non-absorbable mesh for complete rectal prolapse 7 years ago with relief of symptoms for 2 months followed by gradual recurrence over more than 6 years. On examination, complete rectal prolapse with part of the mesh extruding from the rectal mucosa into the lumen was observed (Figure 1). The patient was successfully treated with Altemeier’s p...

Alternating bands of acid and base formation have been detected along the length of the internodal cell of Nitella clavata when it is illuminated, while in the dark this phenomenon is minimal. Chloride influx occurs only or largely in the acid-extruding regions, and this is also a light-dependent ion movement. Chloride efflux is slightly dependent on illumination and is not localized as are H(+...

The diameter of the threaded bottom hole determines whether extrusion can proceed smoothly and fullness tooth shape after extrusion. height rate is an important indicator strength connection. In order to establish relationship between extruded internal thread, this paper takes aluminum alloy M8×1.25 mm thread as example, uses a method combining numerical simulation process test. Obtained changi...

Numerous gases produced in industrial processes are known to cause external irritation of the eye. Unfortunately with the evolution of new techniques the possible hazards to those exposed may not at first be fully appreciated. A session on occupational hazards, physical and chemical injuries, and intoxications was held at the recent Congress of the European Society of Ophthalmology at Amsterdam...

A 48-year-old man with a history of splenic artery pseudoaneurysm requiring transarterial embolization 3 months earlier presented to the emergency department with abdominal pain and fever. Computed tomography showed evidence of embolization coil fragments within the gastrointestinal tract. Upper endoscopy showed a large gastric ulcer with numerous embolization coils extruding into the gastric l...

Histogram Equalization (HE) is an effective technique for contrast enhancement. However, the traditional HE method usually results in extreme over-enhancement, which causes the unnatural look and visual artifacts in the processed image. To solve the problem, we propose a novel Modulated Histogram Equalization (MHE) image contrast enhancement algorithm based on Adaptive Inverse Hyperbolic Tangen...

Multidrug resistance is a phenomenon whereby tumors become resistant to structurally unrelated anticancer drugs. P-glycoprotein belongs to the large ATP-binding cassette (ABC) transporter superfamily of membrane transport proteins. P-glycoprotein mediates resistance to various classes of anticancer drugs including vinblastine, daunorubicin, and paclitaxel, by actively extruding the drugs from t...
