Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Amphiregulin is overexpressed in human cardiac tissue in hypothermia deaths; associations between the transcript and stress hormone levels in cardiac deaths

Annals of Medicine
Background Amphiregulin (AREG) is a growth factor linked to cardioprotection and heart pathology during myocardial stress. Our aim was to investigate cardiac AREG expression, its potential as a postmortem hypothermia marker and its possible stress ...

Thermoregulation in reindeer

Rangifer, 1986
Thermoregulation was studied in Finnish reindeer (Rangifer tarandus L) on captive and herded individuals during 1977-85. Newborn calves maintained a high rectal temperature (Tre) (+39 to +41°C) even at —23°C by increasing heat production 5- to 6-fold ...

Impaired healing following implant placement surgery: A case report of a modern‐day manifestation of scurvy

Clinical Advances in Periodontics, EarlyView.
Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...

Liquid chromatography tandem mass spectrometry for determination of catecholamines using alumina-based extraction method

, 2007
Catecholamines including epinephrine, norepinephrine and dopamine are important neurotransmitters in human species. The levels of catecholamines in biologic sample are utilized to diagnose hypertension, pheochromocytoma and neuroblastoma.

Interventional Mitral Valve Edge‐to‐Edge Repair in Patients Above 85 Years of Age

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mitral valve transcatheter‐edge‐to‐edge repair (M‐TEER) is routinely performed in patients with severe mitral regurgitation (MR) at high operative risk, frequently including elderly patients. Patients ≥ 85 years, however, are frequently excluded in clinical studies.

Determination of catecholamines in urine using hydrophilic interaction chromatography with electrochemical detection

, 2011
The determination of catecholamines in urine was investigated using hydrophilic interaction chromatography (HILIC) as an alternative to the commonly used reversed-phase (RP) method.

Biography as the Missing Variable in Drug Development: A Case for Bio‐Biographical Mechanistic Profiling

Clinical Pharmacology &Therapeutics, EarlyView.
Most clinical trial failures reflect unmeasured biological heterogeneity. Biography — chronic stress, adversity, trauma, and social isolation—is a neglected source of that heterogeneity, operating through the same molecular pathways drugs engage.

Dynamic Network Connectivity: from monkeys to humans

Frontiers in Human Neuroscience
Human brain imaging research using functional MRI (fMRI) has uncovered flexible variations in the functional connectivity between brain regions. While some of this variability likely arises from the pattern of information flow through circuits, it may ...

Increased FGF21 in brown adipose tissue of tyrosine hydroxylase heterozygous mice: implications for cold adaptation

Journal of Lipid Research, 2018
Tyrosine hydroxylase (TH) catalyzes the first step in catecholamines synthesis. We studied the impact of reduced TH in brown adipose tissue (BAT) activation.
