Interspecific reciprocal hybrids between Mesocricetus auratus and M. newtoni

Interspecific Hybrids

The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...

Keloid heterograft in the hamster (Mesocricetus auratus) cheek pouch1 Heteroenxerto de quelóide na bolsa jugal do hamster (Mesocricetus auratus)

Purpose: To study the integration of keloid heterograft in hamster (Mesocricetus auratus) cheek pouch. Methods: The sample is formed by 18 male hamsters, heterogenic ones, aged between 10 and 14 weeks. Keloid fragments were obtained from keloid scars of the breast region of adult female mulatto patient. Each hamster received keloid fragments into both of its pouches, in a total of 36 grafted fr...

Renal function in the hibernating, and hypothermic hamster Mesocricetus auratus.

Plasma and urine concentrations of Na+, K+, and urea were examined in hibernating, hypothermic, and normothermic hamsters. Plasma Na+ and K+ appear unaffected by 48 h of hypothermia (T-re 7 degrees C); however, plasma Na+ increased (P smaller than 0.05) from control values of 125.8 plus or minus 10.2 to 173 plus or minus 9.2 meg/liter in hibernators. Plasma K+ of the hibernator increased to 9.6...
