A 16-kb DNA fragment designated Rp3-1 and cloned from the genome of rat-derived Pneumocystis carinii was found to contain sequences that were repeated approximately 70 times per genome. The repeated sequences in Rp3-1 spanned at least 10.4 kb. Sequences in Rp3-1 were present on each of the 16 P. carinii chromosomes resolved by field inversion gel(More)
Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs. P.(More)
Sequences of hepatitis B virus (HBV) precore regions from 7 patients with HBV and hepatitis C virus (HCV) dual infection and 2 with HBV, HCV, and hepatitis D virus (HDV) triple infection were analyzed. Two patients, 1 with only acute HBV infection and 1 with only chronic HBV infection, were also included for comparison. All patients had antibodies against(More)
The reported incidence of Pneumocystis carinii pneumonia varies in different areas of the world, but little is known about geographic variation in the antibody response to specific antigens. The frequency of anti-P. carinii antibodies in the serum of normal and human immunodeficiency virus (HIV)-infected individuals from five different regions was compared.(More)
It was evaluated the inhibitory action of quercetin-3-O-beta-D-glucuronopyranoside (QGC) on reflux esophagitis and gastritis in rats. QGC was isolated from the herba of Rumex Aquaticus. Reflux esophagitis or gastritis was induced surgically or by administering indomethacin, respectively. Oral QGC decreased ulcer index, injury area, gastric volume, and acid(More)
The previously unknown crystal structure of magnesium perchlorate anhydrate, determined and refined from laboratory X-ray powder diffraction data, represents a new structure type. The title compound was obtained by heating magnesium perchlorate hexahydrate at 523 K for 2 h under vacuum and it crystallizes in the monoclinic space group P2(1)/c. The(More)
Recently, Wireless Sensor Networks (WSN) became one of the most important areas of research in the world. The Quality of Services (QoS) is the cornerstone of WSN efficiency due to providing the network with all requirements for efficient sending and receiving of data. Because of WSN different infrastructures, there are different QoS parameters required for(More)
