An Air-Drying Method for Chromosome Preparations from Mouse Eggs Tập 5 Số 6 - Trang 394-400 - 1966
A Tarkowski
The eggs, after being washed out from the genital tract, are put into hypotonic
(1%) sodium citrate and left to stand at room temperature for 5–15 minutes. The
duration of treatment is not very critical, but later stages, especially
blastocysts, need longer treatment. A microdrop of this solution together with
the eggs is placed on a grease-free slide. A few drops of acetic alcohol (3
parts of abs... hiện toàn bộ
An Air-Drying Method for Meiotic Preparations from Mammalian Testes Tập 3 Số 5 - Trang 289-294 - 1964
E. P. Evans, G. Breckon, C. E. Ford
A suspension is made in isotonic (2.2%) sodium citrate solution from the
contents of the tubules from a whole testis or a testicular biopsy specimen. The
germinal cells are sedimented by centrifuging, leaving most of the sperm in the
supernatant fluid, which is discarded. The cells are resuspended in hypo-tonic
(1%) sodium citrate solution and left to stand at room temperature for 12
minutes, afte... hiện toàn bộ
Yeast stimulation of bone marrow mitosis for cytogenetic investigations Tập 26 Số 1 - Trang 36-40 - 1980
M.R. Lee, F.F.B. Elder
We report a simple, dependable method for stimulating bone marrow mitosis in
small mammals. Subcutaneous injections of a suspension of active baker’s yeast
may elevate the mitotic index as much as six times or more. Additionally, the
metaphases obtained are easily spread when air dried, and the chromosomes are
readily banded. This method should prove useful to investigators who wish to use

Stress activation and genomic impact of Tnt1 retrotransposons in Solanaceae Tập 110 Số 1-4 - Trang 229-241 - 2005

Tnt1 elements are a superfamily of LTR-retrotransposons distributed in the
Solanaceae plant family and represent good model systems for studying regulatory
and evolutionary controls established between hosts and transposable elements.
Tnt1 retrotransposons tightly control their activation, by restricting
expression to specific conditions. The Tnt1A element, originally discovered in
tobacco, is exp... hiện toàn bộ
Digitized and differentially shaded human chromosome ideograms for genomic applications Tập 65 Số 3 - Trang 206-219 - 1994
Uta Francke
Human chromosome ideograms that depict 850 bands, numbered in agreement with
ISCN (1981) nomenclature but based on actual measurements of band sizes and
differentiated by five shades of staining intensity, have been digitized using
commercially available graphics software. They provide for more accurate
estimates of distances within chromosome arms, DNA content of chromosome bands
and correlation ... hiện toàn bộ
Isolation, characterization and mapping of the mouse and human PRG4 (proteoglycan 4) genes Tập 90 Số 3-4 - Trang 291-297 - 2000
Shiro Ikegawa, Masataka Sano, Y. Koshizuka, Yoshihiko Nakamura
PRG4 (proteoglycan 4) has been identified as megakaryocyte stimulating factor
and articular superficial zone protein. PRG4 has characteristic motifs including
somatomedin B and hemopexin domains, a chondroitin sulfate-attachment site and
mucin-like repeats. During a screen of genes implicated in ectopic ossification,
we found a novel mouse gene highly homologous to human and bovine PRG4 genes.

A simplified technique for in vivo analysis of sister-chromatid exchanges using 5-bromodeoxyuridine tablets Tập 18 Số 4 - Trang 231-237 - 1977
James W. Allen, Charles F. Shuler, Robert W. Mendes, Samuel A. Latt
A small tablet of 5-bromodeoxyuridine (BrdU), implanted subcutaneously in a
mouse, provides sustained release of base analog sufficient to effect
substitution of DNA throughout an entire replication period. As illustrated by
studies of mouse bone-marrow and spleen cells in the presence or absence of
cyclophosphamide, this depot method of BrdU administration greatly simplifies in
vivo analysis of s... hiện toàn bộ

Meningioma: a cytogenetic model of a complex benign human tumor, including data on 394 karyotyped cases Tập 93 Số 3-4 - Trang 207-220 - 2001
K.D. Zang
Meningioma is the most frequent tumor of neuroectodermal origin in humans. It is
usually benign. Only a minority of cases shows progression to an anaplastic
tumor (WHO grade II and III). Meningioma is generally a sporadic tumor. Multiple
and familial cases are rare and mostly associated with (hereditary)
neurofibromatosis 2 (NF2). Meningiomas show an unexpectedly high recurrence
rate. Also, comple... hiện toàn bộ
