Euphorbia humifusa Willd. (EH), rich in flavonoids, has long been used for the treatment of bacillary dysentery and enteritis in China, and is known to have antioxidant, hypotensive and hypolipidemic properties. However, the vasorelaxant effect of total flavonoids of EH (TFEH) and action mechanisms are not clearly defined yet. The aim of the present study was to investigate the effects of TFEH on the vascular tension and its underlying mechanisms. Experiments were performed in rat thoracic aorta using the organ bath system...

STUDY DESIGN: Randomized, prospective clinical trial. ANIMALS: A group of 44 healthy client-owned cats presenting for ovariectomy. METHODS: Cats were randomly assigned to one of the two treatment groups: DAM (n=22), which was administered intramuscularly (IM) dexmedetomidine (15 μg kg(-1)), methadone (0...

Sildenafil is an approved drug for the treatment of erectile dysfunction. The drug exerts its action through the relaxation of smooth muscles and the modulation of vascular endothelial permeability. In this work, we tested whether the aforementioned effects of Sildenafil on tumor vasculatures could result in an improvement of anticancer drug concentration in tumor tissues, and hence improve its anticancer effect. Sildenafil when added to doxorubicin showed synergistic anticancer activity against 4T1 breast cancer cells in vitro...

PURPOSE: The purpose of this study was to compare regional elastic properties between anterior and posterior regions of the patellar tendon, and individual quadriceps muscles, over a range of knee flexion angles. METHODS: An isokinetic dynamometer passively positioned the non-dominant knee of 19 young, healthy participants, at 25°, 40°, 55°, 70° and 85° flexion. Shear wave velocity (SWV, an index of tissue elasticity) was measured using ultrasound shear wave elastography in a relaxed (passive) state, confirmed by electromyography...

BACKGROUND: Botulinum toxin A treatment involves injecting botulinum toxin A to relax muscle spasticity. Using ultrasonography, this study examined changes in the muscle architecture before and after treatment to evaluate the influence of botulinum toxin A injection on muscles. METHODS: The participants included 18 children (mean age, 6.2 years) with cerebral palsy who were treated with botulinum toxin A for lower extremity spasticity and 27 healthy children (mean age, 6...

Calcium-dependent cardiac muscle contraction is regulated by the protein complex troponin. Calcium binds to the N-terminal domain of troponin C (cNTnC) which initiates the process of contraction. Heart failure is a consequence of a disruption of this process. With the prevalence of this condition, a strong need exists to find novel compounds to increase the calcium sensitivity of cNTnC. Desirable are small chemical molecules that bind to the interface between cTnC and the cTnI switch peptide and exhibit calcium sensitizing properties by possibly stabilizing cTnC in an open conformation...

BACKGROUND: COPD patients experience a sustained deterioration of several capacities. Those with severe COPD undergo a considerable decline in their physical and functional capacities, but pulmonary rehabilitation (PR) is used to reduce the weakness of such patients. To date, neuromuscular electrical stimulation (NMES) has been used in acute COPD patients but NMES superimposed onto voluntary muscular contraction has not been tested in COPD patients. AIM: The aim of this study was to evaluate the effects of superimposed NMES on the cardiorespiratory performance and functionality of severe COPD patients undergoing a home-based rehabilitation program...

Diaphragmatic myoblasts (DMs) are precursors of type-1 muscle cells displaying high exhaustion threshold on account that they contract and relax 20 times/min over a lifespan, making them potentially useful in cardiac regeneration strategies. Besides, it has been shown that biomaterials for stem cell delivery improve cell retention and viability in the target organ. In the present study, we aimed at developing a novel approach based on the use of poly (L-lactic acid) (PLLA) scaffolds seeded with DMs overexpressing connexin-43 (cx43), a gap junction protein that promotes inter-cell connectivity...

AIM: To investigate whether glucagon-like peptide-2 (GLP-2) influences the neurally-induced responses in gastric strips from mice, since no data are available. METHODS: For functional experiments, gastric fundal strips were mounted in organ baths containing Krebs-Henseleit solution. Mechanical responses were recorded via force-displacement transducers, which were coupled to a polygraph for continuous recording of isometric tension. Electrical field stimulation (EFS) was applied via two platinum wire rings through which the preparation was threaded...

Two dogs presented to the emergency service after accidental ingestion of afloqualone tablets, a muscle relaxant used for back pain in humans. Toxic effects of the drug in these dogs included vomiting, respiratory depression, seizures, ataxia, bradycardia, and hematuria. Treatment consisted of fluid diuresis, furosemide, and propofol. Flumazenil, a gamma-amino butyric acid antagonist, was administered intravenously; however, it was not effective in stopping the seizures in these dogs. Both dogs recovered with supportive treatment...

Tension-type headache (TTH) is the most common type of chronic recurring head pain. It can occur twice as often in women as in men. It is the most common type of headache. Its lifetime prevalence is 30% to 78% in the general population. TTH treatment should be multilevel. It often consists of taking pain medication, muscle relaxants, antidepressants, using biofeedback therapy, acupuncture, and attending behavioral therapy. Several clinical trials also suggest that botulinum toxin (BTX) may be an effective treatment option for such patients...

OBJECTIVE: Identify associations between early care decisions and long-term opioid use in opioid-naïve patients with a new physician consultation for low back pain at which an opioid was prescribed. METHODS: Retrospective study of claims data was used to identify opioid-naïve low back pain patients who were prescribed opioids at the index physician visit. Early care variables captured included additional non-opioid medications prescribed within 14 days, and provider visits or diagnostic imaging within 30 days of the index visit...

Oviducts play roles in reproductive processes, including gametes transport, fertilization and early embryo development. Oviductal transport is controlled by various factors such as endothelins (EDNs) and nitric oxide (NO), smooth muscle contracting and relaxing factor, respectively. EDNs and NO production depend on an ovarian steroid hormone, oestradiol-17β (E2) and E2 quickly exerts their biological functions through G protein-coupled oestrogen receptor 1 (GPER1), which mediates rapid intracellular signalling...

PURPOSE OF REVIEW: Over the past 10 years, there has been a dramatic increase in basic and clinical research involving functional gastrointestinal disorders (FGIDs). New diagnostic and biomarker procedures are helping to identify physiologic disruptions associated with FGIDs on cellular and molecular levels. Simultaneously, clinicians are using new approaches to help manage patients with FGIDs. Among these, an important component of care has been the use of medical foods. These include probiotics, prebiotics, synbiotics, peppermint oil, caraway oil, curcumin, bovine immunoglobulin and many others...

HSPB6(Heat shock protein B6), is also referred to as P20/HSP20. Unlike other many other members of sHSP(small Heat shock protein) family, which tend to form high-molecular-mass oligomers, in solution, human HSPB6 only forms dimers. However, it still exhibits chaperon-like activity comparable with that of HSPB5. It is expressed ubiquitously, with high and constitutive expression in muscular tissues. sHSPs characteristically function as molecular chaperones and HSPB6 also has a molecular chaperone activity. HSPB6 is up-regulated in response to diverse cellular stress or damage and protect cells from otherwise lethal conditions...
