The report describes successful management of 10 women in 2nd and 3rd pregnancy trimesters with EchiTab IgG antivenom after carpet viper (Echis ocellatus) envenoming. All women survived but foetal loss in a victim with delayed presentation and a case of mild hypersensitivity reaction were recorded. Excellent outcomes can be achieved in rural and semi-nomadic populations without specialized care...

Viviparous reptiles have been used as model species for many studies that seek to explain the evolution of viviparity. The vast majority of such studies have focused on the advantage viviparity provides with regards to maternal control of embryonic developmental temperature. However, viviparity may also allow increased control of nutrient transfer, such that mothers adaptively manipulate offspr...

The molecular events underlying the evolution of the Snake Venom Metalloproteinase (SVMP) family from an A Disintegrin And Metalloproteinase (ADAM) ancestor remain poorly understood. Comparative genomics may provide decisive information to reconstruct the evolutionary history of this multi-locus toxin family. Here, we report the genomic organization of Echis ocellatus genes encoding SVMPs from ...

Background: The global incidence of snakebite has become a major concern to the community. This study aimed to evaluate the effect of mango seed kernel methanol extract on metalloproteases in Carpet Viper (Echis ocellatus) venom. Methods: Mango seed kernel methanolic extract was evaluated in vitro for its anti-venom activity and inhibition of metalloproteases of Carpet Viper's (Echis ocellatus...

RNA:DNA ratios in individual red drum (Sciaenops ocellatus) were measured in laboratory-reared larvae and juveniles (6-20 mm standard length; age 16-40 days) to assess the effects of growth, starvation, and die1 periodicity on biochemical condition. RNA: DNA ratios were correlated positively with both absolute (mm day-') and instantaneous (% day-') growth rates. The effect of starvation was eva...

Abstract Marine invertebrates serve as rich sources of secondary metabolites with intriguing chemical diversities and a wide spectrum biological activities. Particularly, marine shell-less sacoglossan mollusks have attracted much attentions due to the fact that apply complex defense agents against their predators. With purpose discovering bioactive develop marine-derived medicines from South Ch...

The molecular mechanisms underlying phenotypic plasticity are not well understood. Identifying mechanisms underlying alternative reproductive tactics (ARTs) in species for which the behavioural and fitness consequences of this variation are well characterized provides an opportunity to integrate evolutionary and mechanistic understanding of the maintenance of variation within populations. In th...
