Balamuthia mandrillaris: Morphology, biology, and virulence.
Balamuthia mandrillaris is a protist pathogen that can cause encephalitis with a fatality rate of >95%. This is due to our incomplete understanding of the pathogenesis and pathophysiology of B. mandrillaris encephalitis. B. mandrillaris has two stages in its life cycle, an active trophozoite stage during which it divides mitotically.

Five wild-growing Artemisia (Asteraceae) species from Serbia and Montenegro: Essential oil composition and its chemophenetic significance [PDF]
In this work, the essential oils (EOs) obtained by hydrodistillation from the aerial parts of five Artemisia species: A. alba Turra, A. pontica L., A. scoparia Waldst. & Kitam., A. vulgaris L., originating from Serbia and A. umbelliformis Lam.

Morphology and Biology of Reptiles [PDF]
tion. Since nine-banded armadillos are born in litters of genetically identical quadruplets, there is no genetic variation within families. Therefore, there can be no selection within families as a result of interactions between sibs. The hypothetical evolution of strong sib altruism in the nine-banded armadillo would have to occur by selection at the ...

Molecular insights into the axon guidance molecules Sidestep and Beaten path
The transmembrane protein Sidestep (Side) functions as a substrate-bound attractant for motor axons in Drosophila. Outgrowing motor axons recognize Side via Beaten path Ia (Beat) and migrate along Side-expressing tissues.

The brown anole dewlap revisited: do predation pressure, sexual selection, and species recognition shape among-population signal diversity? [PDF]
Animal signalling structures are amongst the most variable characteristics, as they are subjected to a diversity of selection pressures. A well-known example of a diverse signalling system in the animal kingdom is the dewlap of Anolis lizards.

Intersexual chemo-sensation in a “visually-oriented” lizard, Anolis sagrei [PDF]
While the conspicuous visual displays of anoles have been studied in great depth, the possibility that these lizards may also interact through chemical signalling has received hardly any consideration.

The 18-kDa translocator protein (TSPO) is a key mitochondrial target by which different TSPO ligands exert neuroprotective effects. We assayed the neurogenic potential of TSPO to induce the neuronal differentiation of pluripotent P19 stem cells in vitro.

Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity [PDF]
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa.

Leptin is critically compromised in the major common forms of obesity. Skeletal muscle is the main effector tissue for energy modification that occurs as a result of the effect of endocrine axes, such as leptin signaling.
