<Case Report> Seven Years' Experience with Cardiac Valve Surgery in Consecutive Patients over Sixty Years of Age

From May 1984 through March 1991, 19 consecutive patients 60 years of age and older (mean age 65.9; range 60-78 years) underwent valvular surgery. These comprised 6 isolated aortic valve replacements (Group 1), 9 isolated mitral valve replacements and one mitral commissurotomy (Group 2), and 3 patients with combined aortic and mitral procedures (Group 3) which included replacement of at least the aortic valve. Carpentier-Edwards bioprosteses were used in most cases. Three patients had undergone previous cardiac operations. Five Patients underwent semi-emergency procedures for acute valve perforation due to infectious endocarditis and prosthetic valve failures. Operative mortality was 11% (2/19 patients). Late death occured in two patients, but the cause of death was not related to prosthetic valves in either. At follow-up, the 15 surviving patients were in New York Heart Association functional class I or II.journal articl

Two-Photon Ionization of Benfluralin in the Presence of Cyclodextrin

Photoionization of benfluralin(N-butyl-N-ethyl-α, α, α-trifluoro-2, 6-dinitro-p-toluidine: Benf.) of typical agricultural chemical was achieved with two-photon two-step excitation by using 266-nm laser pulse irradiation in the presence of cyclodextrins (CDs). The formation of the Benf./CDs inclusion complex was studied by minimize energy of Molecular Mechanics program 2. Ionization of Benf. within the laser flash (5 ns)produced a radical cation of Benf. and hydrated electrons. The ionization quantum yield (Φion) of Benf. in the presence ofα-, β-and γ-CD calculated to be 6.2±0.1%, 16.0±1.0%and 3.3±0.1%, respectively, and it is due to the property of the Benf./CDs inclusion complex. The Φion of Benf. in the presence of CDs(1.0×10-2M)was dependent on the stabilization energy of solvation. In the case of CD concentration (1.0×10-3M),Φion of Benf. was also dependent on the stabilization energy of solvation. Additionally, we found that bulky substituted amino groups is important for the two-photon ionization (TPI)of agricultural chemical when compared with TPI of carbamate based agricultural chemicals. These results suggest the possibility of the photolysis of agricultural chemicals in aqueous solution by using TPI of UV light irradiation.departmental bulletin pape

Throughput Performance of CDMA Slotted ALOHA Systems Based on Average Packet Success Probability Considering Bit-to-Bit Dependence

We propose the analytical calculation method of average packet success probability of CDMA Slotted ALOHA systems, which derives accurate probability, and that is applicable to the system with any spreading codes and any amplitude distributions. In the method, we consider the bit-to-bit dependence of amplitude of signals, used spreading sequences, relative timing delays, and relative carrier phases. This bit-to-bit dependence is the case that the parameters above mentioned are constant for a slot time. By using the method to obtain the average packet success probability, we derive useful throughput performance of CDMA Slotted ALOHA systems on fading channel, and show that the normalized throughput becomes worse in the case of larger spreading factor.journal articl
