    ABSTRACT: Non-porous bare silica nanoparticles, amine modified silica nanoparticles and mesoporous particles, were evaluated as carriers for sodium ibandronate. The synthesized nanoparticles were characterized by SEM, TEM, DLS and porosity. Then, their capacity to incorporate a bisphosphonate drug (sodium ibandronate) and the in vitro release behavior was analyzed by capillary electrophoresis. Mesoporous and amine-modified particles showed higher levels of drug incorporation, 44.68 mg g-1 and 28.90 mg g-1, respectively. The release kinetics from the two types of particles was similar following a first order kinetics. However, when these particles were included into collagen hydrogels only mesoporous nanoparticles had a sustained release for over 10 days. The biocompatibility of mesoporous particles towards Saos-2 cells was also evaluated by the MTT assay observing an increase in cell viability for concentrations lower than 0.6 mg ml-1 of particles and a decrease for concentrations over 1.2 mg ml-1. Furthermore, when these particles were incubated with mesenchymal cells it was observed that they had the capacity to promote the differentiation of the cells with a significant increase in the alkaline phosphatase activity.

    ABSTRACT: Sildenafil ameliorates aortic relaxations in apolipoprotein E knockout (apoE) mice. Now, we tested the hypothesis that endothelial dysfunction (ED) in this model is characterized by contractile hyperresponsiveness to phenylephrine (PE) and that this abnormality may be repaired using sildenafil. The aortic rings were evaluated in apoE mice treated with sildenafil (apoE-sil, 40 mg/kg/day) and compared with apoE and wild-type (WT) mice administered with vehicle (veh). The apoE-veh mice exhibited an imbalance of nitric oxide and reactive oxygen species (NO/ROS) levels and an increased maximum response (Rmax, 20%) and sensitivity (7%) to PE, which were not modified by endothelial removal. Under the prostanoids blockade, vasocontraction was decreased more in apoE-veh (-37%) than in WT (-27%) and apoE-sil (-30%) mice. NADPH-oxidase blockade abolished the enhanced contractile responsiveness in apoE-veh (-33%), without effects in WT and apoE-sil groups. The atherosclerotic lesions and the imbalance of NO/ROS were reduced (40%) in apoE-sil mice. In conclusion, ED in apoE mice was characterized by decreased NO-bioavailability and contractile hyperresponsiveness, due to thromboxane and oxidative stress, and was normalized by sildenafil. The beneficial effects of this phosphodiesterase-5 inhibitor on ED and lipid deposition provide new insights for its use as adjuvant in the treatment of atherosclerosis.

    ABSTRACT: Glucagon-like peptide-1 (GLP-1) is a short peptide that can significantly reduce blood glucose level. Recombination oral long-acting glucagon-like peptide-1 (rolGLP-1), is a GLP-1 analog generated from site-specific mutation of GLP-1. CTB is a non-toxic portion of the cholera toxin and an ideal protein antigen carrier. In this study, we firstly constructed a vector pET-22b (+)-CTB-10×rolGLP-1 to express a fusion protein composed of CTB and ten tandem repeated rolGLP-1 in BL21 (DE3) line of E.coli. The CTB-10×rolGLP-1 was expressed efficiently in the inclusion bodies. The expression product was analyzed by SDS-PAGE electrophoresis and Western blotting. The inclusion bodies were then denatured, refolded and purified by ion exchange chromatography to obtain a high-purity CTB- 10×rolGLP-1. The therapeutic effect of CTB-10×rolGLP-1 was assessed in comparison with 10×rolGLP-1 alone by daily oral-gavage administration up to 10 days in streptozotocin-induced type 2 diabetic mice. The results showed that the level of blood glucose was reduced more effectively and the oral glucose tolerance of mice was improved more significantly with the administration of CTB-10×rolGLP-1. Our results provided a potentially promising oral biological drug for the treatment of type 2 diabetes.

    ABSTRACT: Regeneration in the central nervous system (CNS) of adult mammalian after traumatic injury is limited, which often causes permanent functional motor and sensory loss. After spinal cord injury (SCI), the lack of regeneration is mainly attributed to the presence of a hostile microenvironment, glial scarring, and cavitation. Besides, inflammation has also been proved to play a crucial role in secondary degeneration following SCI. The more prominent treatment strategies in experimental models focus mainly on drugs and cell therapies, however, only a few strategies applied in clinical studies and therapies still have only limited effects on the repair of SCI. Recently, the interests in immunotherapy strategies for CNS are increasing in number and breadth. Immunotherapy strategies have made good progresses in treating many CNS degenerative disorders, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), stroke, and multiple sclerosis (MS). However, the strategies begin to be considered to the treatment of SCI and other neurological disorders in recent years. Besides anti-inflamatory therapy, immunization with protein vaccines and DNA vaccines has emerged as a novel therapy strategy because of the simplicity of preparation and application. An inflammatory response followed by spinal cord injury, and is controled by specific signaling molecules, such as some cytokines playing a crucial role. As a result, appropriate immunoregulation, the expression of pro-inflammatory cytokines and anti-inflammatory cytokines may be an effective therapy strategy for earlier injury of spinal cord. In addition, myelinassociated inhibitors (MAIs) in the injured spinal cord, such as Nogo, myelin-associated glycoprotein (MAG) and oligodendrocyte- myelin glycoprotein (OMgp) are known to prevent axonal regeneration through their co-receptors, and to trigger demyelinating autoimmunity through T cell-mediated harmful autoimmune response. The antagonism of the MAIs through vaccinating with protein or DNA vaccines targeting Nogo, MAG, OMgp, and their co-receptors, may be an effective strategy for the treatment of SCI. However, immunotherapy such as anti-inflammtory therapy or vaccine targeting MAIs or their receptors, accompanied with the potential in risking autoimmune diseases. As a result, in order to optimize the anti-inflammtory therapy and design of protein or DNA vaccines for their use in the future clinical application, we need to further understand the possible mechanisms of neuroprotective immunity. This review presents recent advances in the development of immunotherapy strategies for the treatment of axonal degeneration and demyelination, and improvement of motor function after SCI.

    ABSTRACT: Gymnema sylvestre R. Br. is one of the most important medicinal plants that grows in tropical forests in India and South East Asia. Its active ingredients and extracts of leaves and roots are used in traditional medicine to treat various ailments and they are present in the market for pharmaceutical and parapharmaceutical products. Commercial products based on substances of plant origin that are generally connoted as natural have to be subjected to monitoring and evaluation by health authorities for their potential impacts on public health. The monitoring and evaluation of these products are critical because the boundary between a therapeutic action and a functional or healthy activity has not yet been defined in a clear and unambiguous way. Therefore, these products are considered borderline products, and they require careful and rigorous studies, in order to use them as complement and/or even replacement of synthetic drugs that are characterized by side effects and high economic costs. This review explores the traditional uses, chemical composition and biological activity of G. sylvestre extracts, providing a general framework on the most interesting extracts and what are the necessary studies for a complete definition of the range of activities.

    ABSTRACT: Many natural products influence neurotransmission and are used clinically. In particular, facilitatory agents can enhance neurotransmission and are potentially useful for treating neuromuscular diseases in which muscular weakness is the major symptom. In this work, we investigated the facilitatory effect of apolar to polar fractions of Casearia sylvestris Sw. (guaçatonga) on contractility in mouse phrenic nerve-diaphragm (PND) and chick biventer cervicis (BC) neuromuscular preparations exposed to indirect (via the nerve; 3 V stimuli) and direct (30 V stimuli) muscle stimulation in the absence and presence of pharmacological antagonists. Methanolic and ethyl acetate fractions, but not hexane or dichloromethane fractions, exerted a facilitatory effect on PND (indirect stimulation). The methanolic fraction was chosen for further assays to assess the involvement of: 1) presynaptic sites (axons or nerve terminals), 2) postsynaptic sites (cholinergic receptors, sarcolemma or T-tubules), and 3) the synaptic cleft (acetylcholinesterase enzyme). In preparations treated with d-tubocurarine, the methanolic fraction did not cause facilitation in response to direct stimuli; this fraction was also unable to reverse dantrolene-induced blockade (indirect stimulation). In curarized preparations, the methanolic fraction either restored neuromuscular transmission (mimicking the effect of neostigmine) or failed to cause any recovery of neurotransmission. In the presence of 3,4-diaminopyridine (3,4-DAP), the methanolic fraction decreased twitch amplitude, whereas at a high frequency of stimulation (40 Hz) there was an increase in tetanic tension. In BC preparations, the methanolic fraction did not affect contractures to exogenous acetylcholine or potassium chloride. Incubation with atropine showed there was certain modulation by prejunctional nicotinic receptors, whereas treatment with nifedipine showed that the neurofacilitation required the entry of extracellular calcium. Tetrodotoxin did not prevent the facilitatory effect of 3,4-DAP or neostigmine, but antagonized the response to the methanolic fraction. These findings indicate that neuronal sodium channels have an important role in the facilitatory response to the methanolic fraction, with extracellular calcium entry via calcium channels modulating this neurofacilitation. Possible modulation of prejunctional cholinoceptors was not excluded, particularly in view of certain antagonism by the methanolic fraction at muscarinic receptors. Since facilitation by the methanolic fraction involved enhanced acetylcholine release, use of this fraction could be potentially beneficial in neuromuscular diseases and in the reversal of residual paralysis in the post-operative period or after local anaesthesia.

    ABSTRACT: In the current study we reported cultivation, extraction procedure, analysis and preliminary characterization of the aqueous extract from Cereus peruvianus callus culture and evaluated its anti ulcerogenic activity in vivo models of experimental ulcers in Wistar rats. The obtained aqueous extract from callus (AC) was dialyzed and subjected to freeze-thaw process, providing a possible polysaccharide. The carbohydrate and protein contents of the aqueous extract were estimated at 53.4% and 0.66%, respectively, composed primarily of galactose, arabinose and galacturonic acid, with minor amounts of glucose. This appeared heterogeneous when analyzed by high-performance size-exclusion chromatography and a multiangle laser light scattering detector (HPSEC-MALLS). The AC was found to be significantly effective against ethanolinduced lesions but was ineffective against indomethacin-induced lesions. The callus culture of C. peruvianus is an alternative source for the synthesis of substances originally produced by plants. The calluses grown indefinitely in vitro under controlled conditions are stable tissues, and the aqueous extract from calluses may be used instead of fully developed plants using the protocols described in this study.

    ABSTRACT: Objective: CME-1 is a polysaccharide purified from the mycelia of medicinal mushroom Cordyceps sinensis, its molecular weight was determined to be 27.6 kDa by using nuclear magnetic resonance and gas chromatography-mass spectrometry. The initiation of arterial thromboses is relevant to various cardiovascular diseases (CVDs) and is believed to involve platelet activation. Our recent study exhibited that CME-1 has potent antiplatelet activity via the activation of adenylate cyclase/cyclic AMP ex vivo and in vivo. Methods: The aggregometry, and immunoblotting were used in this study. Results: In this study, the mechanisms of CME-1 in platelet activation is further investigated and found that CME-1 inhibited platelet aggregation as well as the ATP-release reaction, relative intracellular [Ca+2] mobilization, and the phosphorylation of phospholipase C (PLC)γ2 and protein kinase C (PKC) stimulated by collagen. CME-1 has no effects on inhibiting either convulxin, an agonist of glycoprotein VI, or aggretin, an agonist of integrin α2β1 stimulated platelet aggregation. Moreover, this compound markedly diminished thrombin and arachidonic acid (AA) induced phosphorylation of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase 2, c-Jun N-terminal kinase 1, and Akt. Treatment with SQ22536, an inhibitor of adenylate cyclase, markedly diminished the CME-1-mediated increasing of cyclic AMP level and reversed prostaglandin E1- or CME-1-mediated inhibition of platelet aggregation and p38 MAPK and Akt phosphorylation stimulated by thrombin or AA. Furthermore, phosphodiesterase activity of human platelets was not altered by CME-1. Conclusion: The crucial finding of this study is that the antiplatelet activity of CME-1 may initially inhibit the PLCγ2-PKC-p47 cascade, and inhibit PI3-kinase/Akt and MAPK phosphorylation through adenylate cyclase/ cyclic AMP activation, then inhibit intracellular [Ca+2] mobilization, and, ultimately, inhibit platelet activation. The novel role of CME-1 in antiplatelet activity indicates that this compound exhibits high therapeutic potential for treating or preventing CVDs.

    ABSTRACT: L-asparaginase is an effective anti-neoplastic agent used in the chemotherapy of acute lymphoblastic leukemia. One hundred and thirty actinomycete isolates were isolated from several soil samples collected from different localities in Egypt. All these isolates were purified and evaluated for their ability to produce L-asparaginase activity. Among them, strain NEAE-95 was selected and identified as Streptomyces parvus strain NEAE-95 based on morphological, cultural, physiological characteristics and 16S rRNA sequence. The sequence was deposited in the NCBI GenBank database under accession number KJ200341. L-asparaginase production by Streptomyces sp. NEAE-95 was optimized in shake flask culture. The Plackett–Burman statistical design was used for initial screening of sixteen factors for their significances on L-asparaginase production. Among the variables screened, incubation time, L-asparagine and yeast extract had significant effects on L-asparaginase production. The levels of these significant variables and their interaction effects were optimized by Box–Behnken statistical design. As a result, the maximal L-asparaginase production is achieved at the following fermentation conditions: g/L (dextrose 2, starch 20, L-asparagine 14, KNO3 2, yeast extract 2, K2HPO4 2, MgSO4.7H2O 0.1, NaCl 0.1, FeSO4.7H2O 0.01), pH 7, temperature 30°C, agitation speed 200 rpm/min, inoculum size 2%,v/v and incubation time 8 days.
