    Notes: Abstract The Duffy blood group system consists of three alleles, FYA, FYB, and FY. To study the molecular evolution of the three alleles, we established the polymorphism of a dinucleotide (GT) repeat sequence (designated FyGT/ C) in the 3′ flanking region of the Duffy gene, and studied the relationship between FyGT/C and Duffy polymorphism in Japanese, people of African origin, and chimpanzee. By single-strand conformation polymorphism and sequence analysis, five and two alleles were identified in Japanese and Africans, respectively. In 110 random Japanese, the FyGT/C genotypes observed were in agreement with Hardy-Weinberg law. From the sequence of the chimpanzee Duffy gene, including both flanking regions, FYB was identified as the ancestral gene of the human alleles. The FyGT/C sequences associated with the FY allele of Africans were distinct from those of Duffy positives, whereas the FYB and FYA alleles shared common FyGT/C sequences. Thus, it is suggested that the first split took place between the FYB and FY alleles, and the second between the FYB and FYA alleles.

    Notes: Photoluminescence (PL) investigation was carried out on GaInP/GaAs multiple quantum wells structures grown on (001) and (311) B surfaces of GaAs by gas source molecular beam epitaxy. Superlattice structures of GaAs/GaInP grown on (001) GaAs substrate were also studied in comparison. Deep-level luminescence was seen to dominate the PL spectra from the quantum wells and superlattice structures that were grown on (001) GaAs substrate. In contrast, superior optical properties were exhibited in the same structures grown on (311) B GaAs surfaces. The results suggested that GaAs/GaInP quantum well structures on (311) B oriented substrates could efficiently suppress the deep-level emissions, result in narrower PL peaks indicating smooth interfaces. © 1998 American Institute of Physics.

    Notes: Abstract A styrene/divinylbenzene copolymer has been used as precursor for making porous carbons with bimodal pore size distributions (i.e., with both microporosity and mesoporosity). Pretreatment of the as-received copolymer by mild oxidation in air, significantly increased the carbon yield after carbonization. Reactivity studies of the polymer-based chars to CO2 clearly show the influences of some important factors such as carbonization temperature, heating rate, soak time on char reactivities. Bimodal porous carbons were prepared by carbonization of the preoxidized styrene/divinylbenzene copolymer in N2, followed by activation in CO2 at different temperatures to different levels of burnoff. The pore structures of the porous carbons produced have been characterized by various techniques such as gas adsorption and mercury porosimetry. The surfaces of the porous carbons produced, and a commercial carbon adsorbent, have been modified with HNO3 and H2O2 treatment at various conditions. Characterization of the surface oxygen functionality, both quantitatively and qualitatively, has been achieved using techniques such as Linear Temperature Programed Desorption (LTPD) and selective neutralization of bases.

    Notes: Abstract Angiotensin II (Ang II) is an important regulator of the function of medullary thick ascending limb of loop of Henle (MTAL). Recent studies showed that changes in Ang II receptor expression occur and underlie changes in the function of proximal tubules during altered sodium intake. The present experiment was designed to determine (1) whether expression of the type 1 Ang II (AT1) receptor in the MTAL is regulated by altered sodium intake, and (2) the specific pathway(s) mediating sodium-induced AT1 expression in the MTAL. Wistar rats were fed a normal sodium (0.5%, NS), low sodium (0.07%, LS), or high sodium (4%, HS) diet for 2 weeks. Northern blot analysis and radioligand binding showed that in rats fed a normal sodium diet the rank of order for both AT1 mRNA expression and receptor density was outer medulla 〉 cortex 〉 inner medulla. Sodium restriction significantly increased both AT1 mRNA expression and receptor density in the outer medulla. In contrast, neither AT1 mRNA expression nor receptor density in the outer medulla was altered by sodium loading. Losartan treatment (3 mg/kg/per day by oral gavage for 2 weeks) prevented low sodium-induced upregulation of the AT1 receptor in the outer medulla, but it had no effect on AT1 expression in the outer medulla of rats fed a normal sodium diet. Highly purified suspensions of MTAL were isolated from rats fed a normal or low sodium diet. Low sodium intake significantly increased AT1 mRNA level by 184% and AT1 receptor density by 58% in MTALs. Primary cultures of MTAL cells were treated with PBS, Ang II (10-8 M), and Ang II + 17 octadecynoic (17 ODYA, 10 μM). Ang II caused about 2-fold increase in AT1 mRNA levels, and this increase was diminished by about 30% by the addition of 17 ODYA. We conclude that (1) sodium restriction but not sodium loading increases AT1 receptor expression in the MTAL, (2) low sodium-induced upregulation of the AT1 receptor in the MTAL is Ang II-dependent, and (3) Ang II-induced upregulation of the AT1 receptor in the MTAL is mediated, at least in part, by cytochrome P450 pathways.

    Notes: Cells of the human promyelocytic HL-60 line, when treated with a variety of antitumor agents in the presence of the protein synthesis inhibitor cycloheximide (CHX), or with CHX alone, rapidly undergo apoptosis (“active cell death”). It is presumed, therefore, that such cells are “primed” to apoptosis in that no new protein synthesis is required for induction of their death. We have studied apoptosis of HL-60 cells triggered by the DNA topoisomerase I inhibitor camptothecin (CAM) in the absence and presence of CHX and apoptosis induced by CHX alone. Two different flcw cytometric methods were used, each allowing us to relate the apoptosis-associated DNA degradation to the cell cycle position. Apoptosis induced by CAM was limited to S phase cells, e.g., at a CAM concentration of 0.15 μM, nearly 90% of the S phase cells underwent apoptosis after 4 h. In contrast, apoptosis triggered by CHX was indiscriminate, affecting all phases of the cycle: ∼40% of the cells from each phase the cycle underwent apoptosis at 5 μM CHX concentration. When CAM and CHX were added together, the pattern of apoptosis resembled that of cycloheximide alone, namely, cells in all phases of the cycle in similar proportion were affected. Thus, CHX, while itself inducing apoptosis of a fraction of cells, protected the S phase cells against apoptosis triggered by CAM. Because CHX (5 μM) did not significantly affect the rate of cell progression through S phase, the observed protective effect was most likely directly related to inhibition of protein synthesis, rather than to its possible indirect effect on DNA replication. Furthermore, whereas apoptosis (DNA degradation) triggered by CAM was prevented by the serine protease inhibitor N-tosyl-L-lysylchloromethyl ketone (TLCK), this process was actually potentiated by this inhibitor when induced by CHX. The present data indicate differences in mechanism of apoptosis triggered by CAM (and perhaps other antitumor drugs) as compared with CHX. Apoptosis caused by CHX may be unique in that it may not involve new protein synthesis. These data are compatible with the assumption that the loss of a hypothetical, rapidly turning over suppressor of apoptosis may be the trigger of apoptosis of HL-60 cells treated with CHX, whereas de novo protein synthesis is required when apoptosis is triggered by other agents. © 1993 Wiley-Liss, Inc.
