... in Testudines, we studied the hearts of loggerhead sea turtles, Caretta caretta ( n =7), using immunohistochemistry and histology. Surprisingly, we found no evidence of prominent atrial smooth muscle in C. caretta . However, smooth muscle was readily identified in the sinus venosus. Our results suggest...

.... Brown adipose tissue Rat Sucrose overfeeding Immunohistochemistry Ultrastructure Traditionally, the brown adipose tissue (BAT) has been recognised as a highly specialised heat-producing organ in mammals of small body mass, including human newborns ( Himms-Hagen, 1986 ; Nechad, 1986...

...-fertilization, SNP increased ventilation in a concentration-dependent manner. Inhibition of NOS activity with l -NAME or knockdown of nNOS inhibited the hypoxic ( P O 2 =3.5 kPa) ventilatory response. Immunohistochemistry revealed the presence of nNOS in the NECs of larvae. Taken together, these data suggest...

... that in humans. In the present study it was tested whether this is attributable to differences in muscle contractile properties. In biopsies of marmoset m. vastus lateralis (VL) and m. gastrocnemius medialis (GM) ( N =4), fibre-type distribution was assessed using fluorescent immunohistochemistry. In single...

...) in position 3 and methionine (M) in position 8. Reverse transcriptase (RT)-PCR shows that Rhopr-MS is expressed in the CNS and posterior midgut in R. prolixus and immunohistochemistry suggests that an RFamide-like peptide is present in endocrine-like cells in the midgut. Physiological assays using Rhopr-MS...

... is monitoring for changes in their phototactic behavior. In most arthropods, histamine has been shown to play a key role in the visual system. Currently, nothing is known about histaminergic signaling in either D. magna or D. pulex . Here, a combination of immunohistochemistry and genome mining was used...

First, we used synapse-specific immunohistochemistry and proteomics to screen for alterations in the calyx region of the mushroom body, a key structure for memory formation. Using proteomics, we next profiled...

... endocrine cells in the midgut epithelium of the crab Cancer magister ( Mykles, 1979 ). In the years that have followed, these cells have been largely ignored and nothing is known about their hormone content or the functions they play in this species. Here,we used a combination of immunohistochemistry...
