Recessive lethan mutations in the 3A1 to 3C2 region of the X-chromosome of Drosophila melanogaster were detected in 113 of 33,544 sperm treated by feeding 5 mM methyl methanesulfonate in 1% sucrose for 22 hours. Seven of the 113 lethans were sterile, leaving 106 for analysis by complementation tests. With only one exception, these mutants were found to have lesions restricted to single loci. On...

Although Ziziphus jujuba Mill (jujube) is used in folk medicine for hypnotic sedative, anxiolytic, and many other purposes, to date, only a few studies have revealed its sleep-promoting effects related mechanisms. Currently, drugs the treatment of sleep disorders various side effects, so it essential develop safe natural materials. Therefore, we evaluated sleep-enhancing activity mechanism acti...

In the male mouse the X and Y chromosomes pair and recombine within the small pseudoautosomal region. Genes located on the unsynapsed segments of the X and Y are transcriptionally silenced at pachytene by Meiotic Sex Chromosome Inactivation (MSCI). The degree to which MSCI is conserved in other vertebrates is currently unclear. In the female chicken the ZW bivalent is thought to undergo a trans...

BACKGROUND The injection of botulinum toxin (BTX) to reduce facial wrinkles is one of the most frequently performed plastic surgery procedures. The biocompatible hydrogels are injected with BTX for effective tissue augmentation. However, it is difficult to determine the interval of injection for effective tissue augmentation. METHOD BTX and hyaluronate (HA) hydrogels were labeled with zwitter...

For any positive integer n, the Pseudo Smarandache Squarefree function Zw(n) is defined as Zw(n) = min{m : n|mn, m ∈ N}, and the function Z(n) is defined as Z(n) = min { m : n ≤ m(m + 1) 2 , m ∈ N } . The main purpose of this paper is using the elementary methods to study the mean value properties of the function Zw(Z(n)), and give a sharper mean value formula for it.

In the Givental’s work on the Gromov-Witten invariants for projective complete intersections, [G1], the principal role is played by certain formal power series connected with the quantum cohomology of a manifold. One has a manifold X with a natural torus action, with the finite number of fixed points, and one has a power series Zw associated with each fixed point xw. The coefficients of these s...

II Zw 71 (UGC 9562) was classified as a " probable " polar-ring galaxy in the Polar-Ring Catalog ((Whitmore et al. 1990)), based upon its optical appearance. We present 21 cm and optical observations of this galaxy and its companion, the blue star-forming dwarf II Zw 70. Our 21 cm observations show that 5 × 10 8 solar masses of H I is present in a polar ring orbiting II Zw 71, and show a spatia...

We present new measurments of the gas-phase C/O abundance ratio in both the NW and SE components of the extremely metal-poor dwarf irregular galaxy I Zw 18, based on ultraviolet spectroscopy of the two H II regions using the Faint Object Spectrograph on the Hubble Space Telescope. We determine values of log C/O = −0.63±0.10 for the NW component and log C/O = −0.56±0.09 for the SE component. In ...
