BACKGROUND Remitting seronegative symmetrical synovitis with pitting edema syndrome is characterized by symmetrical synovitis with pitting edema in the dorsum of the hands or feet. Most cases of remitting seronegative symmetrical synovitis with pitting edema syndrome are idiopathic, but some are secondary to malignancy, autoimmune disease, or neurodegenerative disorders. Pleural and pericardial...

Variations in the course and distribution of common palmar digital nerves and arteries are rare. A classic common palmar digital nerves and arteries are defined as concomitant. During routine dissection classes to undergraduate medical students we observed formation of each common palmar digital nerve divided into 2 or 3 branches and formed a ring enclosing the corresponding common palmar digit...

Remitting Seronegative Symmetrical Synovitis with Pitting oedema syndrome, a rare inflammatory arthritis, commonly affects people in the older age group. It can present as an acute onset polyarthritis with associated pitting oedema of the extremities. Patients show excellent response to low dose steroids with complete and sustained remissions. It can also be a paraneoplastic manifestation of an...

There were severe pitting corrosions on the surface of transmission gears in diesels. The cause of metal fatigue pitting of gear surface is analyzed in the paper, which based on the contact fatigue experiment of 18Cr2Ni4WA carburizing and quenching gears used in the diesel engine. Causes of pitting on harden tooth surface are studied from three aspects: gear surface residual stress field, oil f...

Background: Few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. Case Presentation: A 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. At ulrasonographic examination, a simple cyst was detected. Sensory response of palmar cutaneous branch of median nerve was absent at the affec...

According to the characteristics of low-carbon steel pitting acoustic emission signal, one new characteristic analysis-WICA is proposed. The main idea of WICA is that based on the independent component analysis blind source separation technology as well as the wavelet transformation decomposition technology, proposed determines the low-carbon steel pitting source number according to the energy ...

Interactions between copper and chlorine disinfectants were examined from the perspective of disinfectant decay and copper pitting corrosion. Sparingly soluble cupric hydroxide catalyzed the rapid decay of free chlorine, which in turn, led to production of less soluble and more crystalline phases of cupric hydroxide. The catalytic activity of the cupric hydroxide was retained over multiple cycl...

The arterial supply of the digits of the forelimb of the Bactrian camel is described. The arteries supplying the digits were the palmar metacarpal and common palmar digital arteries III. The palmar metacarpal artery III was the continuation of the deep medial proximal metacarpal branch which was derived from the medial branch of the radial artery. It gave rise to a nutrient branch, medial branc...

This review attempts to present the current understanding of the mechanism of pitting corrosion of heat treatable aluminium alloys and their welds. The role of alloying elements and intermetallic phases on the corrosion behavior of these alloys has been discussed. Pitting mechanism of aluminiumcopper alloys is specifically discussed. Finally effect of welding on the pitting corrosion of these a...

Biocorrosion, also known as microbiologically influenced corrosion (MIC), is caused by various corrosive biofilms. So far, laboratory experimental MIC pitting tests in the published literature have overwhelmingly focused on sulfate reducing bacteria (SRB) that use sulfate as the terminal electron acceptor because SRB and sulfate are often found at anaerobic pitting sites. Many laboratory pure-c...
