Sympatho‐Excitation in Pulmonary Hypertension: The Potential Role of Pulmonary Arterial Baroreceptors: An Acute Physiologic Intervention Study

open access: yesRespirology, EarlyView.
Pulmonary arterial baroreceptors reflexively stimulate sympathetic nerve activity (SNA) in response to elevated pulmonary artery pressure and distension. In pulmonary hypertension patients, changes in muscle SNA were proportional to changes in pulmonary haemodynamics following nebulised iloprost.

Novel Therapeutics for Chronic Obstructive Pulmonary Disease: From Empirical Bronchodilation to Precision Medicine

open access: yesRespirology, EarlyView.
ABSTRACT Chronic obstructive pulmonary disease (COPD) remains the third leading cause of death worldwide, and conventional bronchodilator‐based therapies have limited efficacy in preventing exacerbations and disease progression. The 2024–2026 period represents a historic inflection point: three mechanistically distinct agents received Food and Drug ...

G Protein–Coupled Receptors in Olfactory Signaling and Related Disorders: Mechanisms and Therapeutic Implications

open access: yesSensory Neuroscience, EarlyView.
This schematic highlights GPCRs as the central hub of olfactory signaling in health and disease. The central GPCR shows odorant activation and downstream pathways. Surrounding quadrants illustrate four GPCR‐mediated themes: odor perception and adaptation, mucosal immunity and regeneration, memory consolidation via neural circuits, and GPCR‐related ...

Dopamine: The Essential Bridge Mediating Obstructive Sleep Apnea and Hippocampus‐Dependent Learning and Memory Impairments

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea is a clinical syndrome that triggers a series of pathophysiologic changes, including disturbed sleep architecture, chronic intermittent hypoxia and hypercapnia, and ultimately severe cognitive dysfunction. The hippocampus plays a key role in various cognitive processes such as learning and memory.

Ca2+-dependent changes in cyclic GMP levels are not correlated with opening and closing of the light-dependent permeability of toad photoreceptors. [PDF]

open access: yes, 1982
We have measured the levels of 3',5'-guanosine monophosphate (cyclic GMP) in isolated retinas from toad to investigate their correlation to the opening and closing of the light-dependent permeability of photoreceptors. When Ca2+-induced changes in cyclic

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Targeted Systemic Therapies for Atopic Dermatitis in Australia: A Narrative Review

open access: yesAustralasian Journal of Dermatology, EarlyView.
ABSTRACT Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease estimated to affect approximately 30% of children and 10%–15% of adults in Australia. Of those with this condition, one in five is estimated to have moderate‐to‐severe disease.
