Objective: To study the biocharacteristics of primary esophageal adenocarcinoma (PEAC) and factors influencing patients’ prognosis and to find rational surgical indications and combined therapy. Methods: To analyze the clinical material of 106 patients with PEAC and compared with that of patients with esophageal squamous-cell carcinoma (ESCC). Results: The overall resectability, morbidity and 30-day...
Carbonization properties and stabilization reactivity of MCMB prepared at a high yield from a particular synthetic naphthalene isotropic pitch with and without carbon black (CB) were evaluated in terms of their fusibility, adhesion ability and graphitizability. MCMB prepared without CB carried much higher hydrogen content which is attributed to aliphatic or naphthenic hydrogens, showing high fusibility...
The preparation of meso-carbon microbeads (MCMB) has been studied by heat-treating two synthetic isotropic naphthalene pitches at 380-430°C for 1-12 hours in the presence of several types of carbon blacks. A larger number of beads with small diameter, ranging from 1 to 10 μm, were obtained. The yields of the beads assessed volumetrically by microscope and gravimetrically by pyridine extraction reached...
