Lactate and hydrogen ions play a predominant role in evoking the exercise pressor reflex during ischaemic contractions but not during freely perfused contractions
J Physiol. 2024 Apr 29. doi: 10.1113/JP286488. Online ahead of print.ABSTRACTWe investigated the role played by lactate and hydrogen in evoking the exercise pressor reflex (EPR) in decerebrated rats whose hindlimb muscles were either freely perfused or ischaemic. Production of lactate and hydrogen by the contracting hindlimb muscles was manipulated by knocking out the myophosphorylase gene (pygm). In knockout rats (pygm-/-; n = 13) or wild-type rats (pygm+/+; n = 13), the EPR was evoked by isometrically contracting the triceps surae muscles. Blood pressure, tension, blood flow, renal sympathetic nerve activity and blood la...

Cardiovascular Reflexes - Vagus as the Key Player
This article intends to explain various reflexes involved in the homeostasis of the cardiovascular system and the role of vagus as the key component in all these reflexes. The article also explains the components of the reflex arc, the stimulus and response, and the role of reflex in a few diseases. This article describes 22 different cardiovascular reflexes in detail.PMID:38685784 | DOI:10.2174/011573403X284831240408053528 (Source: Current Cardiology Reviews)

Influence of Thyroglobulin (Tg) Autoantibodies on Tg levels Measured by Different Methodologies: (IMA, LC-MS/MS and RIA)
CONCLUSIONS: 1) Between-method Tg variability necessitates method continuity when monitoring the Tg trends of TgAb- DTC patients. 2) The presence and concentration of TgAb appeared to have a lowering effect on serum Tg measured by all methodologies (IMA, MS and RIA). 3) Since the reliability of Tg measured in the presence of TgAb is often uncertain, the TgAb trend (measured by the same method) may be a useful surrogate DTC tumor marker.PMID:38686504 | DOI:10.1210/clinem/dgae286 (Source: The Journal of Clinical Endocrinology and Metabolism)

Relationships Among Baseline Concussion Balance Test and Gaze Stability Test Scores in Division-I Collegiate Athletes
CONCLUSIONS: The direction of these relationships indicated that greater Concussion Balance Test errors were associated with greater Gaze Stabilization Test performance. These relationships may be attributed to the difficulty created by the foam conditions and the integration of more complex sensory tasks required to maintain balance during the more difficult conditions.PMID:38688463 | DOI:10.1123/jsr.2023-0254 (Source: Journal of Sport Rehabilitation)

Different neuropsychological and brain volumetric profiles in a pair of identical twins with myotonic dystrophy type 1 indicate a non-genetic modulation of clinical phenotype
Myotonic Dystrophy type 1 (DM1) is an autosomal dominant [1] genetic disorder caused by a CTG triplet repeat expansion within the DM1 protein kinase gene (DMPK) located on chromosome 19q13.3 [2]. DM1 is a heterogeneous multisystemic syndrome characterised by congenital, childhood-juvenile or adult clinical onset [1]. Psychopathological/psychiatric [3-4] and cognitive symptoms including social cognition disorders [5-6] have been previously described. Social cognition is a complex of cognitive and affective functions that entail the recognition of believes and intentions of others (theory of mind), emotional processing, and ...

336. Autonomic Nervous System Coordination Alters PTSD Risk Following Childhood Maltreatment
Individuals with post-traumatic stress disorder (PTSD) often exhibit dysregulation of the autonomic nervous system (ANS), characterized by heightened sympathetic nervous system (SNS) activity or reduced parasympathetic nervous system activity (PNS), which may contribute to the hyperarousal and hypervigilance symptoms commonly observed in PTSD. Additionally, altered ANS functioning has been associated with the severity and persistence of PTSD symptoms. However, most studies have included only one measure of the ANS (i.e., SNS or PNS) without attention to the role of ANS coordination. (Source: Biological Psychiatry)

209. Angiotensin Converting Enzyme Polymorphism Affects Ventricular and Gray Matter Volume in Patients With Recurrent Depression – Interaction With Childhood Trauma
High aldosterone concentrations are associated with worse treatment outcome in MDD. Aldosterone release is regulated by the sympathetic nervous system and the hypothalamus-pituitary-adrenocortical (HPA) axis. A high aldosterone/cortisol ratio is associated with enlarged ventricular and choroid plex volumes and treatment refractoriness. For the angiotensin-converting-enzyme ACE, a key regulator of the RAAS, polymorphisms exist, which are associated with treatment outcome. Also, childhood trauma is associated with increased ventricular volume and aldosterone saliva concentration. (Source: Biological Psychiatry)

208. Heart Rate Variability in Patients With Treatment-Resistant Depression During Ketamine Infusion
Depression is associated with reduced heart rate variability (HRV) and compromised vagal control. Acute ketamine administration triggers significant cardiovascular shifts, increasing heart rate (HR) and blood pressure through sympathetic activation. This autonomic response provides potential understanding of ketamine's antidepressant mechanisms. This investigation examines ketamine's influence on HR and HRV in major depressive disorder (MDD), assessing their potential as treatment response predictors. (Source: Biological Psychiatry)
