Males and females are in conflict over genetic transmission in the evolution of parthenogenesis, because it enhances female reproductive output but deprives the males' genetic contribution. For males, any trait that coerces females into sexual reproduction should increase their fitness.

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized by episodically exuberant heterotopic ossification (HO), whereby skeletal muscle is abnormally converted into misplaced, but histologically normal bone. This HO leads to progressive immobility with catastrophic consequences, including death by

The utility of visible-light-mediated polymerization in tissue engineering has been limited due to the necessary use of potentially cytotoxic coinitiator and comonomer. Here, we report a visible-light-mediated thiol-ene hydrogelation scheme using eosin-Y as the only photoinitiator. Under visible light exposure

Interfacial visible light-mediated thiol-ene photoclick reactions were developed for preparing step-growth hydrogels with multilayer structures. The effect of a noncleavage type photoinitiator eosin-Y on visible-light-mediated thiol-ene photopolymerization was first characterized using in situ photorheometry, gel fraction, and equilibrium swelling ratio.

Freshwater prawn Macrobrachium rosenbergii inoculated with 100 μl novel pathogen spiroplasma strain MR-1008 in logarithmic phase (10(8) spiroplasmas ml(-1)) were examined for alkaline phosphatase (AKP) activity, acid phosphatase (ACP) activity, superoxide dismutase (SOD) activity, catalase (CAT) activity, as well as
