Meiotic behavior of interspecific hybrids between artificially tetraploidized sexual Brachiaria ruziziensis and tetraploid apomictic B. brizantha (Poaceae).

open access: yes, 2010
The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of B.

Hormone therapy (HT) in women with premature ovarian insufficiency or early menopause: Time to think of a new paradigm for healthy aging. A joint FIGO and IMS position paper

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Premature ovarian insufficiency (POI) and early menopause (EM) affect millions of women worldwide. Compared with normal menopause, they confer a longer duration of estrogen deficiency and are associated not only with a shorter lifespan, but with a reduced healthspan, owing to an increased risk of cardiovascular, skeletal, cognitive and ...

Meiotic analysis in induced tetraploids of Brachiaria decumbens Stapf

open access: yesCrop Breeding and Applied Biotechnology, 2011
The meiotic behavior of three tetraploid plants (2n=4x=36) originated from somatic chromosome duplication of sexually reproducing diploid plants of Brachiaria decumbens was evaluated. All the analyzed plants presented abnormalities related to polyploidy,

Maternal and infant gut microbiome

open access: yesiMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Meiotic Behavior of Accessory Chromosomes and their Distribution in Natural Population of Lilium medeoloides A. GRAY

open access: yes, 1958
It has been reported in many plants, notably in maize (Randolph 1941) and rye (Muntzing 1944), that chromosomes of unknown origin are added to the normal chromosome complement.
