Foot deformities are frequently observed in patients with Charcot Marie tooth disease (CMT) and orthopaedic surgery is often required. Currently there is no evidence-based guideline on surgical management and only a few studies which have evaluated long-term outcomes of surgical procedures. The aim of the study was to evaluate longitudinally the effect of foot surgery in a cohort of CMT patients. Twenty-five CMT adult patients were assessed using a comprehensive group of validated scales and questionnaires before and after surgery. A wide range of surgical procedures was performed by one team of dedicated foot ankle orthopaedic surgeons. Foot alignment as measured by the foot posture index, pain, quality of life and callosities significantly improved after one year and the improvement was maintained up to 4 years after surgery. There was a trend towards a reduction in the number of falls post-operatively. Surgery had no effect on fatigue, balance and CMT examination score. Our findings showed significant improvement of pain, foot alignment, callosities and quality of life after surgery and suggested that foot deformity correction in adults with CMT performed in a specialised foot and ankle unit is beneficial.Hospital-acquired infections due to multi-drug resistant Gram-negative organisms (MDRGNO) pose a major threat to global health. A vaccine preventing colonization and consecutive infection with MDRGNO could be particularly valuable, as therapeutic options become increasingly limited. Outer membrane vesicles (OMV) of Escherichia coli strain CFT073 as well as three MDRGNO strains that had caused severe infections in humans were administered intranasally to mice, with and without cholera toxin as an adjuvant. The humoral immune responses were comparatively matched with the sera of patients, who had suffered an infection caused by the respective bacterium. Additionally, systemic and local toxicity was evaluated. Intranasal vaccination with OMV could elicit solid humoral immune responses (total IgM and IgG), specific for the respective MDRGNO in mice; decoration of vital bacterial membranes with antibodies was comparable to patients who had survived systemic infection with the respective bacterial isolate. After intranasal vaccination of mice with OMV no signs of local or systemic toxicity were observed. Intranasal vaccination with OMV may open up a rapid vaccine approach to prevent colonization and/or infection with pathogenic MDRGNOs, especially in an outbreak setting within a hospital. It may also be an option for patients who have to undergo elective interventions in centers with a high risk of infection for certain common MDRGNO. Future studies need to include challenge experiments as well as phase I trials in humans.A rapid ultra-fast liquid chromatography tandem mass spectrometry method was developed and validated to determine ginsenosides Rk1 and Rg5, a pair of isomers, in rat plasma, which was successfully applied to their pharmacokinetic studies. Two ginsenosides were given to male Sprague-Dawley rats via intragastrical and intravenous routes, respectively, and the impact of double bond position on the pharmacokinetic features of the two ginsenosides was elucidated in rats. Ginsenoside Rg3 was used as internal standard and ethyl acetate was applied to extract analytes and internal standard. Chromatographic separation was carried out on a reverse-phase UPLC HSS T3 column (100 × 2.1 mm, 1.8 μm). The flow rate was set to 0.4 ml/min. The fragmentation transition was m/z 765.4 → m/z 101.1 for two ginsenosides. The mobile phases were composed of 0.1% formic acid aqueous solution and acetonitrile. The linear range was 2-1,000 ng/ml for the two ginsenosides. Intra- and inter-day precisions were less then 11.67%, and accuracy fluctuated from -7.44 to 6.78%. The extraction recovery, matrix effect and stability were within acceptable levels. After treatment with ginsenosides Rk1 and Rg5, some differences were found in their pharmacokinetic profiles in rats. The maximum plasma drug concentration and the area under the plasma drug concentration-time curve of ginsenoside Rg5 were about 5 times bigger than those of ginsenoside Rk1 after oral administration, and 3 times higher after intravenous administration. The oral bioavailabilities of ginsenosides Rk1 and Rg5 were 0.67 and 0.97%, respectively. The results indicated that ∆20(22) -ginsenosides showed better pharmacokinetic features than ∆20(21) -ginsenosides with the same glycosylation.In recent years, neurodegeneration has been recognized as a clinical condition that is characterized by neuronal death, dementia, and gradual diminish of cognitive function, poor body coordination and motor disorders. Several studies deciphering cellular and molecular mechanisms show a promising insight for several kinds of damages including neurodegeneration in central nervous system. In addition, there has been an inflammatory key mechanism involved in neurodegenerative disorders. There is a paucity of literature in both cellular- and molecular-mediated targets in damaged neurons at both in vitro and in vivo research models. It has been notified that CNS has a very restricted magnitude of regeneration. Numerous key factors have also been studied and considered as possible culprit of neurodegeneration. Autophagy is a well-known degradation process wherein vesicular machinery as autophagosome transports cytoplasmic contents to the lysosomes. In earlier reports, a bridging connection between autophagy and its associated mechanism has been established. Natural compounds as a neuro-therapeutics have been recognized in neurodegeneration. In our review, we discuss the mechanisms for the onset and progression in neurodegeneration, via inflammation and autophagic machine available in cellular compartments in CNS. This review also discusses about the neuroprotective efficacy of natural compounds against neurodegeneration episodes displays in neuronal platform.Vascular stiffening, an early and common characteristic of cardiovascular diseases (CVDs), stimulates vascular smooth muscle cell (VSMC) proliferation which reciprocally accelerates the progression of CVDs. Osimertinib However, the mechanisms by which extracellular matrix stiffness accompanying vascular stiffening regulates VSMC proliferation remain largely unknown. In the present study, we examined the role of the intermediate-conductance Ca2+ -activated K+ (IKCa ) channel in the matrix stiffness regulation of VSMC proliferation by growing A7r5 cells on soft and stiff polydimethylsiloxane substrates with stiffness close to these of arteries under physiological and pathological conditions, respectively. Stiff substrates stimulated cell proliferation and upregulated the expression of the IKCa channel. Stiff substrate-induced cell proliferation was suppressed by pharmacological inhibition using TRAM34, an IKCa channel blocker, or genetic depletion of the IKCa channel. In addition, stiff substrate-induced cell proliferation was also suppressed by reducing extracellular Ca2+ concentration using EGTA or intracellular Ca2+ concentration using BAPTA-AM.
