BACKGROUND: Chronic musculoskeletal pain conditions are a prevalent and disabling problem. Preventing chronic musculoskeletal pain requires multifactorial treatment approaches that address its complex etiology. Prior cohort studies identified a high risk subgroup comprised of variation in COMT genotype and pain catastrophizing. This subgroup had increased chance of heightened pain responses (in a pre-clinical model) and higher 12month post-operatives pain intensity ratings (in a clinical model)...

Propranolol, a nonselective blocker of β-adrenergic receptors, has become the first-line treatment for complicated infantile hemangiomas. Therefore, its use in the pediatric population has expanded in recent years. In adults, β-blockers have been reported to be the most common causative agents for drug-induced psoriasis. In infants treated with propranolol for infantile hemangioma, the onset of psoriasiform diaper rash has not yet been reported. Here, to the best of our knowledge, we report the first case of psoriasiform diaper rash possibly induced by oral propranolol in an 18-month-old girl with no family history of psoriasis...

Propranolol was first used in 2008 to treat hemangioma; its efficacy and safety have since changed the classical treatment indications. Infantile hepatic hemangioma presents as a spectrum of clinical conditions varying from simple asymptomatic lesions to lethal complications. Tufted hemangioma and Kaposiform hemangioendothelioma are congenital vascular tumors that lead to Kasabach-Merritt syndrome. Hemangiomas, like pure arteriovenous malformations, can cause hyperdynamic heart failure, and diffuse nodular-type hemangiomas can present with hypothyroidism...

Electro-acupuncture (EA) performed in rats and humans using front-limb acupuncture sites, LI-4 and LI-11, and Du-14 and Du-20 increased functional connectivity between the anterior hypothalamus and the amygdala and mobilized mesenchymal stem cells (MSC) into the systemic circulation. In human subjects, the source of the MSC was found to be primarily adipose tissue whereas in rodents the tissue sources were considered more heterogeneous. Pharmacological disinhibition of rat hypothalamus enhanced sympathetic nervous system (SNS) activation and similarly resulted in a release of MSC into the circulation...

OBJECTIVE: Following thermal burn injury, plasma fibronectin degrades within the interstitium; one possible product is epiviosamine-1 (EVA-1, PSHISKYILRWRPK) found within the first type III repeat of plasma fibronectin (FNIII1 ). EVA-1 ameliorates thermal burn injury progression, and binds to and enhances platelet-derived growth factor-BB (PDGF-BB) in promoting cell metabolism, growth and survival; shorter related peptides lose these abilities. Here we study the effect of EVA-1 and shorter peptides for their vasoactivity under quiescent and stress conditions...

Noradrenaline is responsible for eliciting ∼60% of the reflex cutaneous vasoconstriction (VC) response in young adults, whereas the remainder is due to one or more unidentified coreleased sympathetic adrenergic neurotransmitter(s). Inconsistent evidence has placed neuropeptide Y in this role; however, other putative cotransmitters have yet to be tested. We hypothesize that ATP contributes to the reflex cutaneous VC response. Two protocols were conducted in young adults (n = 10); both involved the placement of three microdialysis (MD) probes in forearm skin and whole-body cooling (Tsk  = 30...

BACKGROUND: Resistant hypertension is defined as an uncontrolled blood pressure despite treatment at best-tolerated doses with at least three antihypertensive agents including a diuretic. It is an emerging public health problem. At present clinical trial data on management of resistant hypertension is limited. Management is largely based on observational studies and expert opinions. Propranolol is a nonselective beta blocker. Several studies have confirmed that propranolol has a significant hypotensive action, both when used alone and as an adjuvant therapy...

BACKGROUND: Infantile hemangiomas (IHs) are the most common benign tumors of childhood. They are characterized by a unique clinical course with two phases, proliferation and involution, which are followed by regression. The therapy of infantile hemangiomas was revolutionized in 2008 by the introduction of propranolol, however, the mechanism of its influence on hemangiomas remains unclear. METHODS: The study included 71 patients with IHs, 27 of whom were treated with propranolol while the remaining 44 were used as a comparative group...

Non-selective β-blocker propranolol has been proved by FDA as the first-line agent for infantile hemangioma (IH) with dramatic response. To reduce the side effects caused by systemic administration of propranolol, timolol maleate treatment has been increasingly used as an alternative to systemic β-blockers and watchful waiting for many IH patients in recent years. However, the appropriate indications, drug dosage, dosing regimen, time for initiation, optimal duration, monitoring for side effects still remains controversial...

INTRODUCTION: It is a widely held view that a progressive reduction of beta-cell mass occurs in the progression of diabetes. RAF-1 kinase and pancreas duodenal homeobox 1 (PDX-1) are major factors that promote survival of cells and maintain normal insulin functions. In this study we investigated the effect of a β-adrenergic receptor agonist and antagonist on RAF-1 and PDX-1, and their respective effects on apoptosis and insulin release in RIN-m5F cells. MATERIAL AND METHODS: RIN-m5F cells were cultured in normal (5 mM) and high (25 mM) glucose to mimic diabetic conditions, followed by treatment with 5 µM, 10 µM and 20 µM of isoproterenol and isoproterenol + propranolol for 6, 12 and 24 h...

Molecularly imprinted polymers (MIPs) gained an expansively growing interest in the past few decades. After an initial, explorative period of preparing MIPs exclusively with bulk polymerization, new polymer synthesis routes have been adapted to overcome the drawbacks of the traditional method. Among these the most appealing is precipitation polymerization that results in nano- and microspheres with narrow size distribution and makes the production of MIPs more straightforward. Here, we describe a precipitation polymerization protocol for a common small molecule template, propranolol that is carried out in the conventional way, in dilute monomer solution...
