Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Absence of knockdown mutations in pyrethroid and DDT resistant populations of the main malaria vectors in Colombia

open access: yesMalaria Journal, 2019
Background Knockdown resistance (kdr) is a well-characterized target-site insecticide resistance mechanism that is associated with DDT and pyrethroid resistance.

Status of insecticide resistance and its biochemical and molecular mechanisms in Anopheles stephensi (Diptera: Culicidae) from Afghanistan

open access: yesMalaria Journal, 2019
Background Insecticide resistance of Anopheles stephensi, the main malaria vector in eastern Afghanistan, has been reported previously. This study describes the biochemical and molecular mechanisms of resistance to facilitate effective vector control and

Branching, Capping, and Severing in Dynamic Actin Structures

open access: yes, 2007
Branched actin networks at the leading edge of a crawling cell evolve via protein-regulated processes such as polymerization, depolymerization, capping, branching, and severing.

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

open access: yesCytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Establishment of an innovative and sustainable PCR technique for 1534 locus mutation of the knockdown resistance (kdr) gene in the dengue vector Aedes albopictus

open access: yesParasites & Vectors, 2019
Background Mutation of the voltage-gated sodium channel (VGSC) gene, or knockdown resistance (kdr) gene, is an important resistance mechanism against DDT and pyrethroids for dengue vector Aedes albopictus.

Pyrethroid resistance in the dengue vector Aedes aegypti in Southeast Asia: present situation and prospects for management

open access: yesParasites & Vectors, 2018
Human arboviral diseases transmitted by Aedes aegypti such as dengue, Zika, chikungunya and yellow fever remain global public health threats to date. Of these diseases, dengue fever is particularly prevalent in Southeast Asia.

Psychometric Properties of the Commitment to Exercise Scale in Inpatients With Anorexia Nervosa and Bulimia Nervosa

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Compulsive exercise is a common behaviour among persons with eating disorders, particularly in those with anorexia nervosa (AN) and bulimia nervosa (BN). In the current study, we examined psychometric properties of a German version of the eight‐item Commitment to Exercise Scale (CES) with a four‐point scale response format.

Enhanced surface plasmon resonance absorption in metal-dielectric-metal layered microspheres

open access: yes, 2006
We present a theoretical study of the dispersion relation of surface plasmon resonances of mesoscopic metal-dielectric-metal microspheres. By analyzing the solutions to Maxwell's equations, we obtain a simple geometric condition for which the system ...
