Contribution to the study of insect stress hormones [PDF]

open access: yes, 2009
The present study considers the versatile role of adipokinetic hormones (AKHs). Using the firebug Pyrrhocoris apterus as a model insect, the hypothesis that AKHs mediate stress response mechanisms was explored.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Neuroendocrinological and molecular aspects of insect reproduction4406 [PDF]

open access: yes, 2004
This review summarizes recent advances and novel concepts in the area of insect reproductive neuroendocrinology. The role of 'classic' hormones, such as ecdysteroids and juvenoids, to control reproduction is well documented in a large variety ...

Status and future of recombinant adeno‐associated virus vector manufacturing

open access: yesBiotechnology Progress, EarlyView.
Abstract Sixty years of adeno‐associated virus (AAV) research illustrates a trajectory marked by basic science exploration, iterative innovation, persistent challenges, a number of clinical setbacks, as well as commercial therapeutic triumphs. This continual evolution has led to recombinant AAV (rAAV) becoming a cornerstone of modern gene therapy ...

Peptide hormones in plants

open access: yesMolecular Horticulture
Peptide hormones are defined as small secreted polypeptide-based intercellular communication signal molecules. Such peptide hormones are encoded by nuclear genes, and often go through proteolytic processing of preproproteins and post-translational ...

The role of insect adipokinetic hormones in oxidative stress [PDF]

open access: yes, 2011
In this work, the role of adipokinetic hormones (AKHs) in specific pathological conditions known as oxidative stress (OS) was evaluated in insects. A previous suggestion that the AKHs reverse the OS status elicited by the herbicide paraquat was confirmed

Adipokinetic hormone enhances laminarin and bacterial lipopolysaccharide-induced activation of the prophenoloxidase cascade in the African migratory locust, Locusta migratoria [PDF]

open access: yes, 2002
Lom-AKH-I enhances the activation in vivo of prophenoloxidase in the haemolymph of the African migratory locust, Locusta migratoria, in response to challenge with laminarin.

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.

Regulation of the juvenile hormone titre in the Colorado potato beetle [PDF]

open access: yes, 1978
Three main topics were investigated in regulation of the titre of juvenile hormone in haemolymph of the Colorado potato beetle ( Leptinotarsa decemlineata Say): enzymic breakdown of the hormone; binding and protection of the hormone by carrier proteins ...

Navigating the future of nano‐pesticides: A perspective on design, efficacy, mechanisms, and environmental stewardship

open access: yesiMeta, EarlyView.
Nano‐pesticides are driving a paradigm shift toward sustainable plant protection. This review systematically synthesizes recent advances across four interconnected domains: (i) intelligent formulation design for targeted delivery and controlled release; (ii) interfacial behavior regulation to enhance foliar deposition; (iii) multi‐omics elucidation of ...
