Balamuthia mandrillaris: Morphology, biology, and virulence.

open access: yesTrop Parasitol, 2015
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]

open access: yesJournal of the Serbian Chemical Society, 2021
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]

open access: yesCopeia, 1978
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

open access: yesFrontiers in Physiology, 2022
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.

Chronic Treatment with Melatonin Improves Hippocampal Neurogenesis in the Aged Brain and Under Neurodegeneration

open access: yesMolecules, 2022
Adult hippocampal neurogenesis is altered during aging and under different neuropsychiatric and neurodegenerative diseases. Melatonin shows neurogenic and neuroprotective properties during aging and neuropathological conditions.

Intersexual chemo-sensation in a “visually-oriented” lizard, Anolis sagrei [PDF]

open access: yesPeerJ, 2016
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 brown anole dewlap revisited: do predation pressure, sexual selection, and species recognition shape among-population signal diversity? [PDF]

open access: yesPeerJ, 2018
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.

Neurogenic Potential of the 18-kDa Mitochondrial Translocator Protein (TSPO) in Pluripotent P19 Stem Cells

open access: yesCells, 2021
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.

Melatonin Alleviates the Impairment of Muscle Bioenergetics and Protein Quality Control Systems in Leptin-Deficiency-Induced Obesity

open access: yesAntioxidants, 2023
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.

Development of hypobranchial muscles with special reference to the evolution of the vertebrate neck

open access: yesZoological Letters, 2018
Background The extant vertebrates include cyclostomes (lamprey and hagfish) and crown gnathostomes (jawed vertebrates), but there are various anatomical disparities between these two groups. Conspicuous in the gnathostomes is the neck, which occupies the
