We present a case of fibrous pseudotumor of the epididymis and tunica vaginalis which is one of the rarest paratesticular tumors. Fibrous pseudotumor presents as a solid scrotal mass with normal serum markers. Pathological examination is the only reliable way to make the diagnosis with these tumors exhibiting characteristic macroscopic and microscopic features. It is important to recognize this...

Recently, oxides of Ir(4+) have received renewed attention in the condensed matter physics community, as it has been reported that certain iridates have a strongly spin-orbital coupled (SOC) electronic state, J eff = ½, that defines the electronic and magnetic properties. The canonical example is the Ruddlesden-Popper compound Sr2IrO4, which has been suggested as a potential route to a new clas...

The structure and nature of the metal-metal bonding interaction in the cationic complexes [(eta6-C6Me6)2Ru2(mu2-H)3]+ (1), [(eta6-C6Me6)2Ru2(mu2-H)2(mu2-1,4-SC6H4Br)]+ (2), [(eta6-C6Me6)2Ru2(mu2-H)(mu2-1,4-SC6H4Br)2]+ (3), and [(eta6-C6Me6)2Ru2(mu2-1,4-SC6H4Br)3]+ (4) have been studied at the density functional theory (DFT) level using molecular orbital (MO) theory, bond order (BO) analysis, bo...

Ocular manifestations of cat scratch disease are uncommon. The diagnosis is usually made on the basis of increasing Bartonella henselae serum antibody titers. We report a child presenting with orbital abscess and osteomyelitis who was diagnosed with hepatosplenic cat scratch disease by detection of B. henselae DNA in the orbital abscess fluid.

CLINIC CASE Peribulbar anesthesia is used in daily practice during cataract surgery. It is a safe technique, but not without complications. We present the case of a man who had an orbital abscess secondary to peribulbar anesthesia that led to the perforation of an unknown frontoethmoidal mucocele. DISCUSSION Orbital abscess secondary to an iatrogenic mucocele perforation after anesthesia is a...

9,10-bis(4-(1,2,2-triphenylvinyl)styryl)anthracene (TPE-An) materials have attracted considerable attention in recent years because they have high luminescence efficiency and excellent piezofluorochromic properties, which have potential applications in organic light-emitting display (OLED) area. Scanning tunneling spectroscopy (STS) technique was used to study the piezofluorochromic mechanism o...

We performed angle-resolved photoemission (ARPES) experiments with circularly polarized light and first-principles density functional calculation with spin-orbit coupling to study surface states of a topological insulator Bi2Se3. We observed circular dichroism (CD) as large as 30% in the ARPES data with upper and lower Dirac cones showing opposite signs in CD. The observed CD is attributed to t...

Biomass recalcitrance, the resistance of cellulosic biomass to degradation, is due in part to the stability of the hydrogen bond network and stacking forces between the polysaccharide chains in cellulose microfibers. The fragment molecular orbital (FMO) method at the correlated Møller-Plesset second order perturbation level of theory was used on a model of the crystalline cellulose Iα core with...

INTRODUCTION Rhabdomyosarcoma is the most common primary orbital malignant tumor in children. Orbital lesions represent about 10 % of all the cases of rhabdomyosarcoma. Rhabdomyosarcoma is a rare cause of proptosis in adults. OBJECTIVE To report a case of primary orbital rhabdomyosarcoma in a 45-year-old female. DESIGN Interventional case report. The main outcome measures are a rare cause o...
