Estrogen-related mechanisms in sex differences of hypertension and target organ damage

open access: yesBiology of Sex Differences, 2020
Hypertension (HTN) is a primary risk factor for cardiovascular (CV) events, target organ damage (TOD), premature death and disability worldwide. The pathophysiology of HTN is complex and influenced by many factors including biological sex.

Patterns of the electric organ discharge during courtship and spawning in the mormyrid fish, Pollimyrus isidori [PDF]

open access: yes, 1989
Pollimyrus isidori's electric organ discharge (EOD) is of the pulse type. Patterns of EOD intervals were investigated prior to, during and following spawning behaviors as related with overt behaviors, and with the sound production by the nestbuilding ...

Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]

open access: yes, 2007
An F broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

Electric communication during courtship and spawning in two sibling species of dwarf stonebasher from southern Africa, Pollimyrus castelnaui and P. marianne (Mormyridae, Teleostei): evidence for a non species-specific communication code? [PDF]

open access: yes, 2007
The fixed part of the electrocommunication signal, the electric organ discharge (EOD) waveform, is well differentiated in the two vicariant dwarf stonebasher species, Pollimyrus castelnaui and P. marianne. However, differentiation regarding the variable,
