MS1 full scan based quantification is one of the most popular approaches for large-scale proteome quantification. Typically only three different samples can be differentially labeled and quantified in a single experiment. Here we present a two stages stable isotope labeling strategy which allows six different protein samples (six-plex) to be reliably labeled and simultaneously quantified at MS1...

A 70-year-old man with florid symptoms of hypertrophic osteoarthropathy for over a year presented without radiographic evidence of new bone formation. His symptoms improved after exploratory thoracotomy, but recurred with lesser severity a year later with tumour recurrence on the chest wall. Absence of new bone formation was again demonstrated radiologically as well as by isotope scan.

A 59-year-old man presented with a 7-month history of increasing left shoulder pain. The initial plain films showed near absence of the left scapula and scattered lucent changes in the left humerus. A CT scan confirmed the presence of widespread lytic bony lesions, with a large soft-tissue mass centered around the left scapula. An isotope bone scan demonstrated marked uptake of MDP in the stoma...

UNLABELLED The aim of this study was to elucidate the clinical usefulness of scatter correction with an artificial neural network (ANN) in 99mTc and 123I dual-isotope SPECT. METHODS Two algorithms for ANN scatter correction were tested: ANN-10 and ANN-3 employing 10 and 3 energy windows for data acquisition, respectively. Three patients underwent myocardial or brain SPECT with one of the foll...

We prospectively studied 86 children to assess the value and accuracy of isotope bone scanning in the diagnosis of suspected acute haematogenous osteomyelitis and septic arthritis. The patients were scanned because of difficulty in localising the exact site of the pathology. Characteristic scan appearances were found. In osteomyelitis there was increased or decreased uptake extending beyond the...

NPC is clinically staged according to the International Union Against Cancer (UICC) and American Joint Committee on Cancer (AJCC) staging system (Table 1). Routine staging procedures include history, physical examination including cranial nerve examination, complete blood cell count, serum biochemistry (including liver function test), chest X-ray, nasopharyngoscopy, computed tomography (CT) sca...

AIMS To ascertain the outcome associated with antenatal renal pelvis dilatation; to recommend guidelines for postnatal investigation and determine an upper limit of normal for the anterioposterior dimensions of the fetal renal pelvis. METHODS Infants whose antenatal ultrasound scan showed a fetal renal pelvis of 5 mm or greater were investigated using postnatal renal tract ultrasound and a mi...

Background: This study aimed to evaluate the reaction of organism of laboratory animals on deuterium-depleted drinking diet. To assess the cell energy metabolism, the effect of a liquid medium with different deuterium contents on isolated liver mitochondria of random bred rats and Wistar rats was studied. Methods: This experimental study on the effect of deuterium-depleted drinking water (DDW) ...

intraepiphyseal location of an osteoid osteoma is extremely rare with few cases reported in the literature. they are often present with various atypical and nonspecific clinical features. synovitis of adjacent joint is common and along with chronic inflammation could be misinterpreted as rheumatoid arthritis. initial plain radiographs are often not diagnostic and further radiologic evaluation w...
