BACKGROUND: Leukoencephalopathy with calcifications and cysts is a rare, autosomal recessive cerebral microangiopathy that causes progressive white matter disease, calcifications, and cysts within the brain. It is typically associated with slowly progressive psychomotor regression, seizures, and movement disorders. Although leukoencephalopathy with calcifications and cysts affects only the central nervous system, it demonstrates remarkable neuropathologic and radiologic overlap with Coats plus, a disorder of small vessels of the brain, eyes, gastrointestinal tract, and bone...

The present investigation was carried out to evaluate anti-inflammatory and membrane stabilizing properties of methyl jasmonate (MJ) in experimental rat models of acute and chronic inflammation. The effects of MJ on acute inflammation were assessed using carrageenan-induced rat's paw edema model. The granuloma air pouch model was employed to evaluate the effects of MJ on chronic inflammation produced by carrageenan in rats. The number of white blood cells (WBC) in pouch exudates was estimated using light microscopy...

Asbestos is a mineral-mined form the rocks, consisting in amosite (brown asbestos), crocidolite (blue asbestos) and÷or chrysotile (white asbestos) used in many industries. Researches about the exposure to asbestos dust and asbestosis related diseases started almost a century ago. The first case report of fatal asbestosis disease was published in 1906, in England, by Dr. Hubert Montague Murray. A decade after, asbestos "curious bodies" were firstly described in the lung tissue by Cooke (1926) and McDonald (1927)...

BACKGROUND: Cardiovascular disease occurs at lower incidence in premenopausal females compared with age-matched males. This variation may be linked to sex differences in inflammation. We prospectively investigated whether inflammation and components of the inflammatory response are altered in females compared with males. METHODS: We performed 2 clinical studies in healthy volunteers. In 12 men and 12 women, we assessed systemic inflammatory markers and vascular function using brachial artery flow-mediated dilation (FMD)...

Warthin tumor (WT) is the second most common benign salivary gland neoplasm and has characteristic cytologic and histologic findings. Fine-needle aspiration is a common and useful preoperative diagnostic technique, which sometimes leads to ischemic injury resulting in the infarction of these lesions. Infarcted WT may demonstrate variable gross and histologic alterations that may render the diagnosis challenging, particularly during intraoperative frozen section evaluation. In this study, we collected 11 resection specimens from 9 patients with infarcted WT...

BACKGROUND: The development of platelet-rich fibrin (PRF) drastically simplified the preparation procedure of platelet-concentrated biomaterials, such as platelet-rich plasma (PRP), and facilitated their clinical application. PRF's clinical effectiveness has often been demonstrated in pre-clinical and clinical studies; however, it is still controversial whether growth factors are significantly concentrated in PRF preparations to facilitate wound healing and tissue regeneration. To address this matter, we performed a comparative study of growth factor contents in PRP and its derivatives, such as advanced PRF (A-PRF) and concentrated growth factors (CGF)...

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by a marked eosinophilic infiltrate in the esophageal mucosa. What was once considered a rare disease has nowadays become one of the most frequent esophageal diseases in the Western countries, occupying a place just next to the gastroesophageal reflux disease. EoE etiology and pathogenesis remain largely unknown, although most studies consider that allergic and genetic factors play the most important role...
