Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Analysis of Fang Puncture Wound Patterns in Isfahan Province’s, Iran, Venomous and Non-Venomous Snakes

open access: yesInternational Archives of Health Sciences, 2015
Aims Venomous snake bites are public health problems in different parts of the world. The most specific mainstay in the treatment of envenomation is anti-venom. To treat the envenomation, it is very important to identify the offending species.

Mass landscapes of seven scorpion species: the first analyses of Australian species with 1,5-DAN matrix [PDF]

open access: yes, 2012
Scorpion venoms have been studied for over fifty years; however, the majority of research has focussed primarily on medically important Buthidae species. Additionally, venoms of the estimated 200 species of scorpion native to Australia have received very

Memory Effect of Bacteria‐Killing Properties of Piezo‐Catalysts Nanomaterials through Defect Engineering

open access: yesAdvanced NanoBiomed Research, EarlyView.
It was discovered by Omid Amiri and co‐workers that piezo‐catalysts or piezo materials exhibit an intriguing memory effect in their ability to kill bacteria. The effect is that the piezo materials can retain their activity even days after the mechanical force has been applied. The piezo‐catalysts can preserve their ability to kill bacteria for up to 11

Biochemical and immunochemical characterization of venoms from snakes of the genus Agkistrodon

open access: yesToxicon: X, 2019
In the present work, venoms from five species of the genus Agkistrodon were evaluated in terms of their enzymatic (Phospholipase A2 and caseinolytic) and biological (edema forming, hemorrhagic, procoagulant and lethal) effects.
