OBJECTIVE Converging evidence suggests a role for the anterior cingulate cortex (ACC) in the pathophysiology of anorexia nervosa (AN). This study sought to determine whether ACC volume was affected by starvation in active AN and, if so, whether this had any clinical significance. METHOD Eighteen patients with active AN and age- and gender-matched normal controls underwent magnetic resonance i...
One hundred consecutive admissions to an acute geriatric unit were examined for clinical and radiographic evidence of osteoarthritis (OA) and articular chondrocalcinosis (ACC). Thirty-four patients had ACC. This was age related, the prevalence rising from 15% in patients aged 65-74 years to 44% in patients over 84 years. The commonly involved joints were the knee (25%), public symphysis (15%), ...
A wide variety of human and animal experiments suggest that the anterior cingulate cortex (ACC) is one of the key brain substrates subserving higher order processing of noxious information. However, no sufficient data are now available regarding the mediation by ACC of different levels of pain processing as well as its potential descending modulation of spinal nociception. Using the well-develo...
Ethylene, a gaseous plant hormone, is involved in regulation of various physiological responses during plant growth and development. These include seed germination, abscission, fruit ripening, and plant senescence (Yang and Hoffman, 1984). Plants also produce high levels of ethylene when they are under environmental stresses or pathogen attacks. In ethylene biosynthesis, the precursor Met is co...
BACKGROUND Adenoid cystic carcinoma (ACC) is a subtype of malignant salivary gland tumors (MSGT), in which 90% of cases express cKIT. Dasatinib is a potent and selective inhibitor of five oncogenic protein tyrosine kinases (PTKs)/kinase families including cKIT. We conducted a phase II study to determine the antitumor activity of dasatinib in ACC and non-ACC MSGT. PATIENTS AND METHODS In a two...
Adrenocortical carcinoma (ACC) is a malignant endocrine tumor. Moreover, ACC with invasion into the inferior vena cava is rare. Early diagnosis and treatment are crucial for such cases. Radical surgical resection is the key therapeutic option in ACC.
A mononuclear Fe(II) complex bearing 1-aminocyclopropane-1-carboxylic acid (ACCH) was synthesized and characterized. X-ray crystallography demonstrated that ACC binds to the Fe(II) ion in a bidentate mode constituting the first structural mimic of the expected binding of ACC to the Fe(II) center of the ethylene forming enzyme ACC-oxidase (ACCO). [Fe(BPMEN)ACC]SbF6 also constitutes a functional ...
BACKGROUND Acinar cell carcinoma (ACC) of the pancreas is a rare neoplasm, accounting for 1% of all pancreatic neoplasms. There remains a lack of data regarding the use of systemic therapy in this disease. We present a series of 40 consecutive cases of ACC of the pancreas treated at Memorial Sloan-Kettering Cancer Center, with an emphasis on evaluation of activity of new therapeutic agents. M...
Ethylene inhibits nodulation in various legumes. In order to investigate strategies employed by Rhizobium to regulate nodulation, the 1-aminocyclopropane-1-carboxylate (ACC) deaminase gene was isolated and characterized from one of the ACC deaminase-producing rhizobia, Rhizobium leguminosarum bv. viciae 128C53K. ACC deaminase degrades ACC, the immediate precursor of ethylene in higher plants. T...
