BACKGROUND Receptor for advanced glycation endproducts (RAGE) expression contributes to the impaired angiogenic response to limb ischemia in diabetes. The aim of this study was to detect the effect of increased expression of RAGE on the angiogenic response to limb ischemia in diabetes by targeting αvβ3 integrin with 99mTc-labeled Arg-Gly-Asp (RGD). METHODS Male wild-type (WT) C57BL/6 mice wer...

BACKGROUND Extranodal nasal-type natural killer (NK)/T-cell lymphoma is a very uncommon disease process often mimicking refractory sinusitis. The diagnosis may be discovered after an extensive exclusion process. Careful immunohistochemical evaluation is crucial to differentiate NK/T-cell lymphoma from other malignancies. METHODS AND RESULTS We describe a 46-year-old white man presenting with ...

INTRODUCTION Renal oncocytomas are benign neoplasms derived from cells of the distal renal tubule, and comprise 5% to 7% of primary renal neoplasms. Oncocytomas are mostly asymptomatic, and the majority of tumors are discovered incidentally. In this case report, we present a case of a patient with a giant oncocytoma arising from her left kidney. CASE PRESENTATION We describe a 25-year-old Tur...

BACKGROUND The pathogenic mechanisms of UV-induced skin lesions of lupus erythematosus (LE) are unknown. In a recent study of pathogenic mechanisms of polymorphic light eruption (PLE), significantly more Langerhans cells (LCs) persisted in the epidermis after UVB overexposure than in healthy individuals. Interestingly, the same phenomenon was observed in one subacute cutaneous lupus erythematos...

Leydig cell tumor as a sex-cord stromal tumor is a relatively uncommon ovarian tumorin bitch. A 10-year-old female German Shepherd dog was presented because of protrusion of a large tumor-like mass of 16 × 14 × 7 cm in dimensions from her vagina. After stabilization of the patient, the mass was removed surgically and concurrent ovariohysterectomy was also performed. Macroscopically, the healthy...

The immunofluorescent localization of antisera to human glomerular basement membrane (GBM), collagen, and smooth muscle actomyosin was examined in 15 specimens of normal renal tissue and 98 specimens from patients with renal disease. The anti-GBM and anticollagen antisera normally localize to GBM, while antiactomyosin localizes to the mesangium. Diabetic nephropathy revealed a striking expansio...

Background: Experimentally-induced total sleep deprivation (TSD) and chronic partial sleep restriction (CPSR) leads to the emergence of cognitive impairments. This is hypothesized to result from a consequent neuroinflammation which may also hasten the neurodegenerative processes. Neuroinflammatory markers such as tumor necrosis factor-alpha (TNFα) are thought to be potential culprits in SD-indu...

Rationale: Primary central nervous system diffuse large B-cell lymphoma (PCNSL) is a rare and aggressive entity that resides in an immune-privileged site. The tumor microenvironment (TME) the disruption of immune surveillance influence pathogenesis immunotherapy resistance. Despite growing knowledge on heterogeneous therapeutic responses, no comprehensive description PCNSL TME available. We hen...

From June 1992 to March 1993, a group of patients suffering from different types of warts were treated with intralesional injections of bleomycin sulfate. This study reviews the literature concerning this modality of treatment and the pathophysiology and immunohistopathology of warts and options for treatment. In this prospective study, a combination of a I mg/mL solution of bleomycin in...
