The Beijing Spectrometer (BES) p ex eriment has observed purely leptonic decays of the D, meson in the reaction e+e+ D$D; at a c.m. energy of 4.03 GeV. Three events are observed in which one D, decays hadronically to +r, li*“K, or K”li, and the other decays leptonically to ova or l-v,. With the assumption of p-r universality, values of the branching(More)
We investigated dexamethasone therapy for preventing delayed encephalopathy after carbon monoxide (CO) poisoning. Eighty healthy male rats were exposed to CO and randomly divided into four groups: hyperbaric oxygen treatment (H), treatment (D), combined hyperbaric and dexamethasone treatment (C), and a control (M) group in which the rats inhaled CO to coma(More)
Our project is designed to clone a 1.3kb gene fragment of telomerase catalytic subunit gene which contains seven reverse transcriptase motifs and specific region with conserved sequence termed "T motif". The gene fragment was amplified by PCR and was inserted into expression vector pET28-b. The recombinant plasmid was induced by IPTG for 4h and a 52KD(More)
The Beijing Spectrometer (BES) Collaboration has observed exclusive pair production of D, mesons at the Beijing Electron-Positron Collider (BEPC) at a center-of-mass energy of 4.03 GeV. The D, mesons are detected in the &r+, r*‘K+, and 1?oK+ decay modes; two fully reconstructed events yield the value (3.9 -l.g -1.1 ‘5*1 +l**)% for the D, branching fraction(More)
Although related bone marrow transplantation (BMT) is effective for thalassemia, less than 30% of patients have sibling donors. Here, we report unrelated BMT in nine thalassemic children using a high-resolution HLA typing technique to identify donors. HLA mismatches between donors and recipients were 0, 1 and 2 in 2, 5 and 2 cases, respectively. The results(More)
Objective: To explore the biomarkers that applied to pulmonary acute respiratory distress syndrome (ARDS) and extrapulmonary ARDS respectively. Methods: A total of 49 eligible patients with ARDS were selected from Department of Respiratory intensive care unite (ICU) , Department of General ICU and Department of Emergency ICU, the Second Affiliated Hospital(More)
OBJECTIVE Allogeneic marrow transplantation is a curative therapy for thalassemia, but no more than 30% of patients have HLA-indentical sibling marrow donor. The selection of alternative donors of unrelative marrow and the study on the probability of treating thalassemia major with unrelated donor bone marrow transplantation are of importance. METHODS(More)
OBJECTIVE To verify the pathogenesis in Chinese and to investigate the genetic rule of X-linked lymphoproliferative disease (XLP) therein. METHODS The case history of a proband of XLP, male, aged 1 year and 5 months, who died 40 days after hospitalization, was reviewed. Fourteen his family members were interviewed for the development history, anamnesis,(More)
