Recent studies have shown that mutations in a newly described RNA editing enzyme, activation-induced cytidine deaminase (AID), can cause an autosomal recessive form of hyper IgM syndrome. To determine the relative frequency of mutations in AID, we evaluated a group of 27 patients with hyper IgM syndrome who did not have defects in CD40 ligand and 23(More)
Congenital patients who lack natural killer (NK) cell activity experience repeated polymicrobial infections. NK cell activity varies significantly among normal people, but it is unknown whether this variation influences their ability to fight infections. This study examined this concern. NK cell activity and other variables, i.e. age, sex, performance(More)
During disease progression in myelodysplastic syndromes (MDS), clonal blasts gain a more aggressive nature, whereas nonclonal immune cells become less efficient via an unknown mechanism. Using MDS cell lines and patient samples, we showed that the expression of an immunoinhibitory molecule, B7-H1 (CD274), was induced by interferon-gamma (IFNgamma) and tumor(More)
The present manuscript describes kinetic behaviour of the glass transition and non-equilibrium features of the "Nematic-Isotropic" (N-I) phase transition of a well known liquid crystalline material N-(4-methoxybenzylidene)-4-butylaniline from the effects of heating rate and initial temperature on the transitions, through differential scanning calorimetry(More)
We studied bactericidal activity of 10% povidone-iodine, 0.5% chlorhexidine gluconate, and 0.5% chlorhexidine in 80% ethanol on four strains of methicillin-resistant and two strains of methicillin-susceptible Staphylococcus aureus. The pathogen was exposed to each of the disinfectants for 15, 30, 60, 120, and 240 s at room temperature. The inocula from(More)
BACKGROUND AND OBJECTIVES Stellate ganglion block can promptly relieve acute herpetic pain (AHP) involving the trigeminal and cervical regions. However, repeated blocks are needed to maintain pain relief in most patients with severe AHP. Because continuous epidural block is easily performed using an indwelling catheter, we compared the effect of high(More)
The sensory spread and hemodynamic effects of low-dose thoracic epidural anesthesia were closely studied in 13 elective preoperative patients undergoing thoracotomy. An epidural catheter was inserted at the T4-5 or T5-6 intervertebral space and 5 ml 0.5% plain bupivacaine was injected. Cardiac output was measured by suprasternal Doppler method in all(More)
BACKGROUND AND OBJECTIVES The authors report the role of epidural anesthesia and analgesia (EAA) and the incidence of epidural puncture-related complications in a university hospital in Japan. METHODS Epidural anesthesia and analgesia was the major (39.7%) technique when administering 40,010 anesthetics. For the upper and the lower abdominal procedures,(More)
The TARGET system is an online database that can be easily accessed by physicians. The registration of one's own chronic myeloid leukemia (CML) patients in the TARGET system makes it possible to share experiences among physicians, and, thus, may facilitate appropriate treatment for patients. Patients were registered in the TARGET system from October 2003 to(More)
