    Notes: Abstract In recent years there have been many studies demonstrating a correlation between increased arterial blood pressure and altered lipid profiles, and there has been an especially positive correlation between high cholesterol levels and blood pressure. There are differences between the various reports that are important. In our study the lipid distribution in 105 hypertensive patients with mild or moderate arterial hypertension according to WHO criteria without clinically or ultrasonographically apparent atherosclerosis was compared to the lipid distribution in 65 age-matched healthy persons. On the epidemiological level a significant, positive association was found between LDL serum levels (P ≤ 0.001), Apo B serum levels (P ≤ 0.001), serum triglyceride levels (P ≤ 0.05) and VLDL serum levels (P ≤ 0.01) and arterial hypertension. However, in contrast to recent reports, no significant difference was found between total serum cholesterol levels in normotensives and hypertensives, and there was no difference in HDL serum levels. No evidence could be found for a significant increase in lipoprotein (a) serum levels in hypertensives.

    Notes: Summary In a double-blind, placebo-controlled study the antihypertensive efficacy and tolerability of a single morning dose of either 10 mg bisoprolol (n=26) or 20 mg nitrendipine (n=27) were investigated. Blood pressure was measured by three techniques: (1) Casual blood pressure 24 h after the dose; (2) ambulatory 24-h whole-day monitoring; and (3) self-recorded blood pressure in the morning 24 h after the dose (6–8 a.m.) and in the evening (6–8 p.m.). After 4 weeks of therapy bisoprolol had produced a highly significant reduction in blood pressure as assessed by casual, ambulatory day- and night-time monitoring, and self-measured morning and evening readings. Bisoprolol was significantly more effective than nitrendipine, which did not induce a significant reduction in the ambulatory night-time recordings. Whole-day ambulatory blood pressure profiles showed an antihypertensive effect of bisoprolol throughout the entire 24-h period. 24-h blood pressure curves after nitrendipine demonstrated a markedly shorter duration of action, with no reduction in early morning blood pressure. Adverse effects and tolerability of the two drugs were comparable. The average changes in systolic and diastolic blood pressure after bisoprolol and nitrendipine in 2-h periods of ambulatory monitoring (6–8 a.m. and 6–8 p.m.) and self-measured blood pressure (6–8 a.m. and 6–8 p.m.) showed a good agreement between ambulatory and self-measured blood pressure determinations with no significant difference between the methods. The results show that 24 h antihypertensive efficacy was more pronounced for bisoprolol than for nitrendipine at the doses studied. Further, self-measured blood pressures at home were suitable for accurate estimation of the 12-h and 24-h antihypertensive efficacy of the two drugs. The methodological findings of this study have important implications for further pharmacological trials investigating the duration of action of antihypertensive drugs.

    Notes: Abstract The use of an effusive beam of titanium atoms crossed with a CW single-mode tunable dye laser has allowed the high-resolution, Doppler-free study of the isotope shifts between50Ti,48Ti and46Ti, for seven 3d 2 4s 2 a3 F J → 3d 2 4s 4p z 5 D J , visible transitions of Ti I. The measurements show without ambiguity the existence of a non-negligible field shift. Using the values of the nuclear radii of titanium (coming from muonic X-ray measurements), it is possible to determine the respective values of the field and mass shifts.

    Notes: Abstract High accuracy measurements of hyperfine structure due to47Ti and49Ti in the 3d 2 4s 2 a 3 F 2−3d 2 4s4p z 5 D 1 absorption line at σ=18482.772 cm−1 have been performed by use of a Doppler-free experiment, where a beam of titanium atoms is crossed by a CW single mode tunable dye laser. They have allowed for the determination of isotope shifts between46Ti,47Ti,48Ti,49Ti and50Ti. By use of accurate values of mean square nuclear charge radii for the even isotopes, it has been possible to separate mass shifts from field shifts and to determine accurate values for the mean square nuclear charge radii of47Ti and49Ti. The field shift presents a marked odd-even staggering.

    Identification of a set of yeast genes coding for a novel family of putative ATPases with high similarity to constituents of the 26S protease complex (1994)

    Notes: There is accumulating evidence for a large, highly conserved gene family of putative ATPases. We have identified 12 different members of this novel gene family (the YTA family) in yeast and determined the nucleotide sequences of nine of these genes. All of the putative gene products are characterized by the presence of a highly conserved domain of 300 amino acids containing specialized forms of the A and B boxes of ATPases. YTA1, YTA2, YTA3 and YTA5 exhibit significant similarity to proteins involved in human immunodeficiency virus Tat-mediated gene expression but more significantly to subunits of the human 26S proteasome. YTA1 and YTA2 are essential genes in yeast. Remarkably, the cDNA of human TBP-1 can compensate for the loss of YTA1. Preliminary experiments indicate that YTA1 is a component of the 26S protease complex from yeast. Our findings lead us to propose that YTA1, YTA2, YTA3 and YTA5 function as regulatory subunits of the yeast 26S proteasome. YTA10, YTA11 and YTA12 share significant homology with the Escherichia coli FtsH protein, and together with YTA4 and YTA6 may constitute a separate subclass within this family of putative ATPases.

    Molecular analysis of yeast chromosome II between CMD1 and LYS2: The excision repair gene RAD16 located in this region belongs to a novel group of double-finger proteins (1992)

    Notes: We have analysed a region some 30 kb centromere distal form PHO5 on the right arm of yeast chromosome II and determined the nucleotide sequence of a 8.95 kb DNA segment from this region. By this analysis we were able to derive the precise location and the transcriptional orientation of CMD1, ALG1, SSN6 and LYS2. An open reading frame of 2370 bp was locatlized between SSN6 and LYS2, which has recently been identified (Schild et al., 1991) to be the RAD16 gene. The putative gene product, 790 amino acids in length, reveals several interesting freatures. It contains a nuclear target singnature and shares several blocks of similarity with the yeast recombinational repair protein RAD54 and the nuclear factor SNF2 (SW12), which is required for teh transcriptioal activation of a number of yeast genes. The similarity blocks in these three proteins are reminiscent of those found in the helicase superfamily. Furthrmore, RAD16 contains a novel ‘double-finger’ motif, which has been encountered in a variety of proteins from different organisms that are suggested to interact with DNA and are involved in diverse functions including site-specific recombination, DNA repair, and transcriptional regulation. The putative gene product of RAD16 then is the first example of a proteins in which the novel double-finger motif is found to be combined with a poteintial DNA helicase framework.

    Notes: In the framework of the EC programme for sequencing yeast chromosome II, we have determined the nucleotide sequence of a 70 kb region. Subsequent analysis revealed 35 open reading frames, 14 of which correspond to known yeast genes. From structural parameters and/or similarity searches with entries in the current data libraries, a preliminary functional assessment of several of the putative novel gene products can be made. The gene density in this region amounts to one gene in 1.98 kb. Coding regions occupy 75% of the total DNA sequence. Within the intergenic regions, potential regulatory elements can be predicted. The data obtained here may serve as a basis for a more detailed biochemical analysis of the novel genes. The complete nucleotide sequence of the 70 kb segment as depicted in Figure 1 has been deposited in the EMBL data library under Accession Number X78993.
