Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 8, Page 887-893, October 2026.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Reduced Food Availability Amplifies Behavioral Depression and Impairs Locomotor Performance After Immune Challenge in Xenopus laevis

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 8, Page 894-902, October 2026.
Food restricition amplifies the reduction in voluntary locomotion after immune challenge in Xenopus laevis, ilustrating the energetic trade‐off between immunity and performance. ABSTRACT Mounting an immune response and locomotor activity are energetically costly processes that can generate trade‐offs affecting energy allocation, muscle performance, and

Repeated Moderate and Severe Heat Exposure Has Divergent Effects on Skeletal Muscle Mitochondrial, Proteostatic and Neuromuscular Outcomes in Mice

open access: yesActa Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Repeated heat exposure may promote adaptive remodeling or cumulative tissue burden depending on thermal dose, but its graded molecular and functional consequences during recovery remain unclear. We examined whether repeated moderate (39°C) and severe (41°C) whole‐body hyperthermia produce distinct skeletal muscle trajectories involving ...

Stressor‐ and Tissue‐Specific Regulation of the Corticotropin‐Releasing Factor System Across Epithelial Tissues in Rainbow Trout

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
The gill and intestinal corticotropin‐releasing factor (CRF) systems in rainbow trout are differentially regulated by immune, osmotic, and nutritional stressors. Seawater transfer suppressed gill CRF system transcription and induced time‐dependent changes in the middle intestine. An immune challenge (vaccination) altered only intestinal CRF expression.

Lactation is Associated with Accelerated Postpartum Pelvic Floor Muscle Recovery in a Pregnant Simulated Birth Injury Model

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
ABSTRACT Healthy pelvic floor muscles (PFMs) are essential for proper pelvic floor function. The biggest risk factor for PFM dysfunction is injury sustained during vaginal childbirth, yet the factors that facilitate or impair PFM recovery from birth injury remain unknown.

The Impact of Overtraining on Anxiety‐Like Behavior and Tight Junction Proteins of the Blood–Brain Barrier in Mice

open access: yesBrain and Behavior, Volume 16, Issue 9, September 2026.
ABSTRACT Purpose: Overtraining Syndrome (OTS) is a chronic maladaptive condition characterized by persistent performance decline due to excessive training and inadequate recovery. OTS is associated with mood disturbances, but the underlying neurobiological mechanisms remain unclear.

Sleep Deprivation Induces Glial Dysfunction, Synaptic Loss, Metabolic Imbalance, and Cognitive Impairment in 12‐Month‐Old Mice: Protective Effects of D30

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Sleep deprivation induces neuroglial atrophy and dendritic spine loss, accompanied by metabolic disturbances involving 1‐methyladenosine, citric acid, L‐kynurenine, and berberine, indicating disrupted neuroenergetic and immunometabolic homeostasis. These alterations result in deficits in spatial recognition, fear conditioning, nesting, and Morris Water

Cancer‐related pain: A bidirectional modulator of cancer progression

open access: yesClinical and Translational Medicine, Volume 16, Issue 9, September 2026.
CRP and tumour progression engage in a dynamic, bidirectional circuit mediated by multiple mechanisms involving neuroimmunology and cancer ‐neuroscience. Analgesic interventions may affect tumour progression, while anticancer therapies can influence pain. Targeting pain in cancer may have promising therapeutic value in cancer progression.
