Management of inorganic elements by overwintering physiology of cold hardy larvae of European corn borer (Ostrinia nubilalis, Hbn.) J. Comp. Physiol. B (IF 2.0) Pub Date : 2024-03-13
Abstract The European corn borer (Ostrinia nubilalis, Hbn.), enters diapause, a strategy characterized by arrest of development and reproduction, reduction of metabolic rate and the emergence of increased resistance to challenging seasonal conditions as low sub-zero winter temperatures. The aim of this study was to investigate the potential role of inorganic elements in the ecophysiology of O. nubilalis

The intersection of sleep and synaptic translation in synaptic plasticity deficits in neurodevelopmental disorders J. Comp. Physiol. B (IF 2.0) Pub Date : 2024-02-24
Abstract Individuals with neurodevelopmental disorders experience persistent sleep deficits, and there is increasing evidence that sleep dysregulation is an underlying cause, rather than merely an effect, of the synaptic and behavioral defects observed in these disorders. At the molecular level, dysregulation of the synaptic proteome is a common feature of neurodevelopmental disorders, though the mechanism

Mechanism of post-tetanic depression of slow muscle fibres J. Comp. Physiol. B (IF 2.0) Pub Date : 2024-02-12 Joseph Foon Yoong Hoh
A brief tetanic stimulation has a very different effect on the subsequent isometric twitch force of fast and slow skeletal muscles. Fast muscle responds with an enhanced twitch force which doubles that of the pre-tetanic value, whereas slow muscle depresses the post-tetanic twitch by about 20%. Twitch potentiation of fast muscle has long been known to be due to myosin light chain 2 phosphorylation

Phylogenetic conservation of the interdependent homeostatic relationship of sleep regulation and redox metabolism J. Comp. Physiol. B (IF 2.0) Pub Date : 2024-02-07
Abstract Sleep is an essential and evolutionarily conserved process that affects many biological functions that are also strongly regulated by cellular metabolism. The interdependence between sleep homeostasis and redox metabolism, in particular, is such that sleep deprivation causes redox metabolic imbalances in the form of over-production of ROS. Likewise (and vice versa), accumulation of ROS leads

Involvement of sodium–glucose cotransporter-1 activities in maintaining oscillatory Cl− currents from mouse submandibular acinar cells J. Comp. Physiol. B (IF 2.0) Pub Date : 2024-02-03
Abstract In salivary acinar cells, cholinergic stimulation induces elevations of cytosolic [Ca2+]i to activate the apical exit of Cl− through TMEM16A Cl− channels, which acts as a driving force for fluid secretion. To sustain the Cl− secretion, [Cl−]i must be maintained to levels that are greater than the electrochemical equilibrium mainly by Na+-K+-2Cl− cotransporter-mediated Cl− entry in basolateral

Abstract Mus musculus enters a torpid state in response to caloric restriction in sub-thermoneutral ambient temperatures. This torpid state is characterized by an adaptive and controlled decrease in metabolic rate, heart rate, body temperature, and activity. Previous research has identified the paraventricular nucleus (PVN) within the hypothalamus, a region containing oxytocin neurons, as a location

Developmental, physiologic and phylogenetic perspectives on the expression and regulation of myosin heavy chains in mammalian skeletal muscles J. Comp. Physiol. B (IF 2.0) Pub Date : 2023-06-05 Joseph Foon Yoong Hoh
The kinetics of myosin controls the speed and power of muscle contraction. Mammalian skeletal muscles express twelve kinetically different myosin heavy chain (MyHC) genes which provides a wide range of muscle speeds to meet different functional demands. Myogenic progenitors from diverse craniofacial and somitic mesoderm specify muscle allotypes with different repertoires for MyHC expression. This review
