How to use chemical triggers and invertebrate tests in the lower tiers of a bioaccumulation testing strategy.

There are now a reasonable number of invertebrate central pattern generator (CPG) circuits described in sufficient detail that a mechanistic explanation of how they work is possible. These small circuits represent the best-understood neural circuits with which to investigate how cell-to-cell synaptic connections and individual channel conductances combine to generate rhythmic and patterned outp...

doi: 10.4088/JCP.12m08083). Thus, the meditation proved efficient in the activation of the ventrolateral pre-frontal cortex and in increasing the connectivity between amygdala and pre-frontal cortex. Both these neurological changes are believed to be beneficial for the reduction of GAD symptoms. Such findings demonstrating that soft healing approaches like meditation can be backed up by hard ev...

The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...

BACKGROUND There is scarce information about European folk knowledge of wild invertebrate fauna. We have documented such folk knowledge in three regions, in Romania, Slovakia and Croatia. We provide a list of folk taxa, and discuss folk biological classification and nomenclature, salient features, uses, related proverbs and sayings, and conservation. METHODS We collected data among Hungarian-...

1. Two high molecular invertebrate hemoglobins (the erythrocruorins of Lumbricus terrestris and of Nereis virens) as well as the low molecular erythrocruorin of Glycera dibranchiata Ehlers were studied. Their physical chemical properties were compared with those of vertebrate hemoglobin. 2. The hemin of the blood pigment of Glycera dibranchiata Ehlers was shown to be identical with that of vert...

The ubiquitin-proteasome system controls a variety of essential intracellular processes through directed protein turnover. The invertebrate proteasome has recently gained increasing interest with respect to central physiological processes and pathways in different taxa. A pitfall in proteasome activity assays, represented by the trypsin-like, chymotrypsin-like or caspase-like site, lies in the ...

In species with paternal genome elimination, males do not pass on their genes through their sons (they do not make it into their sons' sperm) and might therefore favour daughters. The same is true for the bacteria, because these are only transmitted through the cytoplasm in scale insect eggs (and so through the maternal line of their hosts). Females, however, benefit from both male and female o...
