    Notes: Abstract The quantization of the Hall resistivity ρxy in the form of plateaus in the dependence of ρxy on the magnetic field B is observed in the semiconductors Bi2Te3 and Sb2Te3; the minima of the transverse magnetoresistivity ρxx correspond to the start of the plateaus. The quantization of ρxy is due to the presence of a current-carrier reservoir. An impurity band with a high density of states or a different band with a much higher current-carrier effective mass serves as the reservoir.

    Notes: Abstract Laparoscopic surgery is being used in an increasing number of operations today. We have been performing various types of laparoscopic techniques in our department. A problem we sometimes have encountered involves a ring of pressure that develops around the surgeon's thumb at the end of the procedure, which is accompanied by an area of paresthesia in the distribution of the lateral digital nerve. We report our own experience and a small review of the literature.

    Notes: Abstract Members of the RAB protein family are important regulators of vesicular fusion and trafficking. A putative new member of the RAB family of genes was identified through a public database search, and its full-length cDNA was isolated from a human fetal brain cDNA library. The predicted protein product of the gene consists of 190 amino acid residues and has 87% identity with rat Rab26. Thus, we designated this gene as the human RAB26-related gene. Reverse transcription-coupled polymerase chain reaction (RT-PCR) demonstrated that the RAB26-related messenger RNA was predominantly expressed in adult and fetal brain. Furthermore, an RT-PCR experiment for brain subregions showed that the mRNA was highly expressed in the amygdala, cerebellum, caudate nucleus, and hippocampus. By PCR-based analysis with both a human/rodent monochromosomal hybrid cell panel and a radiation hybrid panel, the gene was mapped to the chromosome 16p13.3 region between markers WI-7742 and WI-3061. The RAB26-related gene consists of eight exons that span about 44 kb of the genome DNA.
