Se han realizado numerosos estudios acerca de la dieta del oso andino, sin embargo poco se conoce sobre los pequeños vertebrados que consume. El presente trabajo da a conocer nueve especies de vertebrados (siete roedores y dos aves) como presas del oso andino, por medio del análisis de seis fecas provenientes de dos localidades Upa (Amazonas) y Lagunas Arreviatadas (Cajamarca) en el norte de Perú. Seis de estos registros son nuevos ítems alimenticios y una nueva familia Caviidae. Tan solo en la localidad de Upa se encontraron restos de vertebrados. Adicionalmente los pequeños mamíferos no voladores fueron muestreados en esa localidad. Nuestros resultados sugieren que el oso andino sería una especie generalista, si bien puede tener preferencias en la ingesta de plantas, en el caso de los vertebrados pareciera consumirlos según los encuentra en el ambiente.
PGD for HLA typing is a procedure that can be performed when an affected child
requires a transplant to treat a non-hereditary disorder related to the
hematopoietic and/or immune system. Hematopoietic stem cell transplantation from
an HLA-identical donor provides the best treatment option. Three conventional
ovarian stimulation procedures for IVF were performed in a couple with a
10-year-old child diagnosed with T-cell acute lymphoblastic leukemia of high
risk. Trophectoderm biopsy and aCGH examination were performed on 15
blastocysts, three on the first IVF procedure, four on the second cycle, and
eight on the third. Three euploid blastocysts HLA-compatible with the genome of
the affected child were identified. One euploid blastocyst HLA-compatible with
the affected child was warmed and transferred, resulting in an HLA-matched live
birth. In conclusion, combined aCGH for aneuploidy screening and Karyomapping
may be performed in a single biopsy procedure.
Se describe un caso de interacción génica por reversión del color de pelaje del hamster sirio. Se cruzaron parentales blanco acromeliano y gris oscuro, obteniéndose en la F, animales con pelaje tipo agutí y en la F, se obtuvo cuatro mutantes para el color del pelaje. Se discute la importancia de la serie C, y no se descaRta la existencia de una interacción epistática entre el pelaje gris y el blanco acromeliano.
A continuación presentamos la primera serie Peruana lograda íntegramente en nuestro país, que marca el inicio de una nueva era en el adelanto médico que ayuda a la pareja a conseguir el hijo no logrado. Para la primera serie Peruana de Fertilización Asistida por Procedimientos de Alta Complejidad, fueron seleccionadas 20 parejas que habían recibido diversos tratamientos de infertilidad por un mínimo de 48 meses antes de ser incorporadas al programa.
two-tailed t-test. RESULTS: Between December 2010 and November 2020, a total of 1475 TE embryo biopsies were tested, with results reported on 1428 samples (96.8%). The overall aneuploid rate was 42.7% and the mutation positive rate was 50.9%. The aneuploid rate for age-matched controls was 44.6% (Table 1). When divided by CGG repeat length, the aneuploid rate for full FMR1 mutation cases was greater than that of the age matched controls, but this finding was not statistically significant.CONCLUSIONS: Overall, we did not observe an increase in aneuploid rates among all FMR1 mutation carriers compared to age-matched controls. Results indicate a trend toward higher aneuploidy rates with increasing repeat length, however further studies are needed to corroborate these findings. This information could be useful in counseling FMRI carriers regarding IVF and PGT outcomes.IMPACT STATEMENT: We do not see a decreased rate of euploid results in TE biopsy samples from FMR1 expansion carriers, therefore maternal agerelated risks for aneuploidy are appropriate to use for counseling this population.References: 1.
