Perturbation Theory in the Cobar-Bar Resolution
Presented
by Corr. Member of the Academy N. Berikashvili,
Abstract. In this article one specific
property of cobar-bar resolution of graded algebra H is shown: any
perturbation of differential in this resolution can be "shorten",
i.e. it is equivalent to one, which maps the generator module into itself. Any
such short perturbation can be interpreted as -algebra structure on H. This
allows to obtain some known results about the classification of
differential-graded algebras.
Key words: perturbation, bar construction, -algebra.

Abstract. The influence of partial

of grapevine has been studied. The enhancement of source activity under

Total Paradoxical Sleep Deprivation through Partial
Deprivation of Slow-Wave Sleep
Presented
May 24, 1999
Abstract. Analysis of the results of total
paradoxical sleep deprivation (PSD) through partial deprivation of deep
slow-wave sleep (DSWS) clearly indicates that the formation of PS need in the
sleep-wakefulness (S-W) cycle occurs exclusively during SWS and especially
during DSWS. The phase of wakefulness cannot be involved in PS need
accumulation. On the contrary, it someway prevents PS need accumulation even in
that case when its fragments arise during SWS. These data are in conformity
with our earlier evidence that the replacement of PS in the cycle by the
fragments of active wakefulness equivalent in length to mean PS duration, leads
to a complete and selective PS deprivation without accumulation of the need for
it. In a normal S-W cycle wakefulness and PS appear to be competitive and in
this competition it is wakefulness that has an advantage. This is perhaps
reasonable and necessary for a precise determination of the place of PS in the
S-W cycle. Otherwise there would be disturbance of the normal integrative
activity of the brain and disruption of the S-W cycle that not infrequently
manifest itself in a number of psychoneurologic diseases.
Key words: paradoxical sleep, slow-wave sleep, sleep-wakefulness

Changes of the Rat Brain and Liver Cell Nuclear
Matrices Poly (ADP-ribose) Polymerase and DNA Topoisomerase II
Activities by X-irradiation
Presented
October 12, 1998
Abstract. It is shown, that X-irradiation
of isolated rat brain and liver matrices at the doses of 1.7 Gy and 6.7 Gy
increases their endogenous poly(ADP-ribose) polymerase activity in a
dose-dependent manner. This indicates that the breaks induced in DNA tightly
bound with matrices is a reason for poly(ADP-ribose) polymerase activity
increasing. It is revealed also, that DNA topoisomerase II activity of the
isolated matrices of both brain and liver cells is inhibited after
X-irradiation of rats as compared to control matrices isolated from
nonirradiated rats. This testifies to the involvement of DNA topoisomerase II activity
in DNA repair and gives possibility to suppose that the induction of
ADP-ribosylation directly of DNA topoisomerase II in vivo after
X-irradiation of rats decreases topoisomerase activity of isolated matrices.

Abstract.. HLA promoter alleles of DQA1 and
DQB1 genes were analyzed in a group of 65 Czech healthy individuals and 54
members of 13 RA multicase families by PCR and oligonucleotide hybridization.
QAP4.1 and QBP3.1 were the most frequent alleles (gf=0.315, gf=0.254) due to
the linkage disequilibrium with DQA1*0501 and DQB1*0301. The second most
frequent allele QAP1.2 (gf=0.162) was found to be common for DR2 alleles.The
analysis of RA multicase families showed promoter alleles and haplotypes
similar to those reported in the healthy population. QBP3.21 was in a complete
positive association with DQB1*0302-DRB1*04, except DQB1*0302-DRB1*0408, where
was detected QBP3.1, associated also with DQB1*0301-DRB1*0401. Promoter
