Bone marrow contains fat and water. Using magnetic resonance (MR) T1-weighted images, fat appears light gray and water appears dark gray. Black or low signal structures include normal cortical bone, bone islands, hemosiderin deposits, calcification, ossification, metal artifact, gas, and foreign
Acute esophageal necrosis (AEN), also known as Gurvits syndrome, black esophagus, or acute necrotizing esophagitis, is a rare clinical entity and an unusual reason for upper gastrointestinal bleeding. It is typically described in critically ill patients with multiple medical conditions, arising from
SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis and osteitis) is a relatively rare entity. The therapeutic approach of patients with SAPHO syndrome has included multiple drugs with varying success and incoherence responses. The therapy is still empirical today. SAPHO syndrome is commonly
In the early 1980s, in search of the cytokine that triggers disease- associated weight loss and lethal shock, Anthony Cerami and Bruce Beutler purified "cachectin." They soon found out that their malevolent cytokine already had another name-tumor necrosis factor (TNF)-and was being lauded as a
Growth plate chondrocytes of embryonic chick femurs were examined by electron microscopy, cytophotometry and autoradiography. Apart from the well-described 'light' chondrocyte, a different 'dark' type of chondrocyte was present, comprising 10 - 35% of the cell population. They were found at all
"Dark" neurons were produced in the cortex of the rat brain by hypoglycemic convulsions. In the somatodendritic domain of each affected neuron, the ultrastructural elements, except for disturbed mitochondria, were remarkably preserved during the acute stage, but the distances between them were
Cytokines have been implicated in a variety of physiological processes involving lymphoid tissue development, lymphocyte activation, and control of regenerative processes such as wound healing. The first characterization of a cytokine implicated in abolishing or killing tumor cells - the tumor
CD40 is a tumor necrosis factor receptor superfamily member expressed by immune and non-immune cells. CD40:CD154 interactions mediate T-dependent B cell responses and efficient T cell priming. Thus, CD40 is a likely candidate to play roles in autoimmune diseases in which activated T and B cells
A case of endogenous Serratia marcescens endophthalmitis in a patient with diabetes, end-stage renal disease, and an indwelling venous catheter is reported. The patient presented with a tan hypopyon and elevated intraocular pressure. Diagnosis was established by positive blood, vitreous,
A phosphodiesterase inhibitor (PDEI), Ibudilast, which has been in wide use for the management of bronchial asthma and cerebrovascular disease in Japan, was tested for its clinical efficacy on experimental autoimmune encephalomyelitis (EAE) in Dark August rats. The severity of acute EAE was
Morphological aspects of the formation and fate of neurons that underwent dramatic ultrastructural compaction ("dark" neurons) induced by 4-aminopyridine epilepsy were compared in an excitotoxic and a neighboring normal-looking area of the rat brain cortex. In the excitotoxic area, the later the
To determine which clinical or CT imaging factors can help accurately identify complicated sigmoid volvulus (SV), defined as irreversible bowel ischaemia or necrosis requiring emergent surgery in patients with SV.We performed a retrospective study of 51
