We report the microwave synthesis of several bis(thiosemicarbazones) and the rapid gallium-68 incorporation to give the corresponding metal complexes. These proved kinetically stable under 'cold' and 'hot' biological assays and were investigated using laser scanning confocal microscopy, flow
The development of gallium-68 -1,4,7,10-tetraazacyclodecane-1,4,7,10-tetraacetic acid ((68)Ga-DOTA) compounds was made possible due to the chemistry of (68)Ga, which matches the pharmacokinetics of many peptides, specially the chelators DOTA and DOTAderivatives with the formation of stable (68)Ga
A patient with medulloblastoma of the cerebellum developed dyspnea and hypoxemia. Pulmonary function tests showed decreased lung volume and diffusing capacity, while the chest radiographs initially showed only mild interstitial infiltrates. Repeated gallium scans showed diffuse lung uptake and
We investigated the effects of gallium (Ga) and tin (Sn) compositions on the structural and chemical properties of Ga-Sn-mixed (Ga:Sn) oxide films and the electrical properties of Ga:Sn oxide thin-film transistors (TFTs). The thermogravimetric analysis results indicate that solution-processed oxide
A 75-year-old man presented with fever, dyspnoea, chest pain and findings suggestive of severe pneumonia including hypoxia and bilateral chest infiltrates. He was given antibiotics without significant effect. He took long-term amiodarone therapy for persistent atrial arrhythmias and also had a
Gallium arsenide is an important semiconductor material marketed in the shape of wafers and thus is not hazardous to the end user. Exposure to GaAs particles may, however, occur during manufacture and processing. Potential hazards require evaluation. In 14-week inhalation studies with small GaAs
BACKGROUND
Hypoxia imaging is an important field in radiopharmaceutical research since hypoxic cells are very resistant to radiation treatment and diffusional limitations restrict the efficacy of chemotherapy. Gallium-68 is a widely used radionuclide for positron emission tomography (PET) due to the
BACKGROUND
Due to in vitro data suggesting antitumor activity with gallium nitrate, we sought to evaluate the safety and activity in patients with androgen-independent prostate cancer.
METHODS
Patients were eligible for this study if they had an ECOG performance status of < or = 2, stage D2
(68)Ga is an attractive radiometal for use in positron emission tomography (PET) imaging. The success of (68)Ga-based agents is dependent on a chelator that exhibits rapid radiometal incorporation, and strong kinetic inertness to prevent transchelation of (68)Ga in vivo. The linear chelating agents
A case of neoplastic angioendotheliosis of the lung is reported. A 56-year-old man presented with a 2-month history of fever, increased serum lactic dehydrogenase, and arterial hypoxemia. Chest radiography revealed diffuse reticulonodular opacity, whereas CT scanning showed diffuse small nodular
A 34 year-old male pigeon breeder developed a sudden fever, cough, and dyspnea with diffuse nodular shadows on the chest X-ray film and computer tomogram. His symptoms and diffuse nodular shadows on the chest X-ray film improved and gallium (Ga) scintigram showed no accumulation of 67Ga-citrate in
Fifteen patients, eleven males and four females, with amiodarone induced pulmonary disease were studied. Their ages ranged between 52 and 79 (mean = 64.0) years. 66% of the patients were taking a daily dose of 200 mg of amiodarone. The time elapsed between the initial dose and the diagnosis of the
A 59-year-old male patient presented with left chest discomfort on admission. His medical history included encephalitis in childhood and his smoking history was 20 cigarettes per day for 40 years. A physical examination showed an anemic and edematous face with weak respiratory sounds in the left
