The discovery of Chromera velia, a free-living photosynthetic relative of apicomplexan pathogens, has provided an unexpected opportunity to study the algal ancestry of malaria parasites. In this work, we compared the molecular footprints of a eukaryote-to-eukaryote endosymbiosis in C. velia to their equivalents in peridinin-containing dinoflagellates (PCD) to reevaluate recent claims in favor o...

Freshwater sponges (Porifera; Spongillina) include 6 families. Some of them are endemic of ancient lakes Baikal, Tanganyika, Ohrid and Malawi. Others families are cosmopolitan and inhabit inland waters worldwide. Freshwater sponges are important for cleaning of water due their filter activity and are often main part of benthos in the lakes. The taxonomy of freshwater sponges is difficult that c...

We report the assembly of the 14,054 bp near complete sequencing of the mitochondrial genome of the legume pod borer (LPB), Maruca vitrata (Lepidoptera: Crambidae), which we subsequently used to estimate divergence and relationships within the lepidopteran lineage. The arrangement and orientation of the 13 protein-coding, 2 rRNA, and 19 tRNA genes sequenced was typical of insect mitochondrial D...

BACKGROUND Doxorubicin causes a chronic cardiomyopathy of unknown pathogenesis. We investigated whether acquired defects in mitochondrial DNA (mtDNA) and interconnected respiratory chain dysfunction may represent a molecular mechanism for its late onset. METHODS AND RESULTS Rats were treated weekly with intravenous doxorubicin (1 mg/kg) for 7 weeks, starting at 11 weeks of age (group B). Cont...

The paleobiodiversity of the Volutidae (Mollusca: Gastropoda) of the Ranikot Group (Sindh, Pakistan) and particularly of the Lakhra Formation (SBZ 5 biozone, Earliest Eocene), is reconsidered on the basis of new material collected during recent field trips. Ten new species are described (Mitreola brohii sp. nov., Lyrischapa vredenburgi sp. nov., L. brevispira sp. nov., Athleta (Volutopupa) cith...

Each variety is susceptible of being applied in several divers ways ; thus, the Franklinic electricity may be charged into a patient isolated on a glass-legged couch ; the patient is then said to be in an " electric bath sparks may be taken from any part of his body by presenting a rounded brass-knob ; or sparks may be discharged at a non-isolated patient by a coxi* ductor attached to a plate f...
