Corazonin Stimulates Ecdysteroid Synthesis during the Molting Process of the Swimming Crab, Portunus trituberculatus

open access: yesBiology
The neuropeptide corazonin (Crz) exerts diverse physiological effects in insects, yet its role in crustaceans remains elusive. The abundant expression of Crz receptor (CrzR) in the Y-organs of several crustaceans suggests a potential involvement of Crz ...

Evidence of parental care as a newly identified reproductive isolating barrier

open access: yesJournal of Animal Ecology, EarlyView.
Behavioural variation can contribute to reproductive isolation and can be an important driver of speciation. Here, we show that a previously undescribed mechanism, parental care, can function as a postzygotic reproductive isolating barrier when dysregulated in hybrids.

Quantitative receptor radioautography in the study of receptor-receptor interactions in the nucleus tractus solitarii

open access: yesBrazilian Journal of Medical and Biological Research, 1998
The nucleus tractus solitarii (NTS) in the dorsomedial medulla comprises a wide range of neuropeptides and biogenic amines. Several of them are related to mechanisms of central blood pressure control.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Is PP56 (D-myo-inositol-1,2,6-trisphosphate) an antagonist at neuropeptide Y receptors?

open access: yes, 1993
PP56 (D-myo-inositol-1,2,6,-trisphosphate) has been reported to specifically inhibit neuropeptide Y-mediated effects in vasculature, heart and brain; because of its reversible but non-competitive antagonism interaction with neuropeptide Y receptor ...

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Comparative effectiveness, safety and acceptability of pharmacological and psychosocial interventions for the treatment of cannabis use disorder: A network meta‐analysis

open access: yesAddiction, EarlyView.
Abstract Aim Our primary aim was to conduct a network meta‐analysis (NMA) for the effectiveness, safety and acceptability of all psychosocial interventions and all pharmacotherapies for cannabis use disorder (CUD). Methods We conducted a NMA of studies identified from two completed systematic reviews examining the effectiveness, safety and ...
