title: Antinociceptive activity of Thyme (Thymus vulgaris L.) and interactions with neurotropics and analgesics

description: The plant world represents an important source of potential therapeutic agents, but concomitant administration of herbal and conventional medications may result in interactions with subsequent beneficial or adverse effects. This study was designed to examine the analgesic effect of thyme tincture and thyme syrup, two commonly used thyme formulations, and their interactions with codeine, paracetamol, pentobarbital and diazepam in mice. The identification and quantification of thymol and carvacrol were carried out by GC/MS and GC/FID. The analgesic activity was studied using a hot plate method. Effects of thyme syrup on diazepam-induced motor coordination impairment in rotarod test and on pentobarbital-induced sleeping time were also determined. Thymol (175.3 µg/mL and 9.73 µg/mL) and carvacrol (10.54 µg/mL and 0.55 µg/mL) concentrations were measured in tincture and syrup, respectively. Thyme syrup and tincture exhibited effective analgesic activity in the hot plate pain model. Pretreatment with thyme formulations reduced analgesic activity of codeine, and potentiated the analgesic activity of paracetamol. Co-administration of thyme formulations has led to potentiation of diazepam and pentobarbital depressive central nervous system effects. Thyme formulations interacted with tested conventional drugs, probably through interference with their metabolic pathways and succeeding altered concentrations and pharmacological effects.

title: Clinacanthus nutans: Its potential against diabetic vascular diseases

description: Diabetes is an independent risk factor for the development of cardiovascular disease, with approximately 80% of cardiovascular mortality and morbidity linked to vascular complications such as atherosclerosis. It has been estimated that up to one-third of patients with diabetes mellitus use some form of complementary and/or alternative medicine. One plant that has received attention from diabetic patients for its perceived antidiabetic properties is Clinacanthus nutans, a member of the Acanthaceae family that is known as snake grass. Ethnomedical applications of this herb have been identified for the treatment of certain conditions, including fever, diabetes, skin rashes, and insect bites. This review aims to assess the potential of C. nutans to be used in the prevention and/or treatment of diabetic vasculopathy. Evidence for antidiabetic, anti-inflammatory, and dyslipidemic properties of C. nutans, as shown from experimental studies, is presented and discussed. Diabetes, inflammation, and hyperlipidemia are known to play significant roles in the initiation and severity of diabetic cardiovascular disease; thus, targeting these factors might be beneficial for preventing and/or treating diabetic vasculopathy.

title: Emerging intervention of antidepressant with DMARD in non-cancerous nociceptive persistent pain associated depression in FCA induced rheumatoid arthritic rats

description: Rheumatoid arthritis (RA) is a chronic inflammatory disorder that causes pain, systemic complications and premature mortality. Depression has also been identified as a problem for persons with RA. This association remaining significant even after the degree of disease activity is controlled. In the present study, the efficacy of combination therapeutic effect of antidepressant (amitriptyline) with Disease Modifying Anti rheumatoid drug (leflunomide) was determined in rheumatoid arthritis pain associated depression in Freund’s complete adjuvant (FCA) induced arthritic rats. Drug treatment was started 9 days after induction of FCA induced arthritis in rats. The antiarthritic activity was assessed by measuring paw volume, weight-bearing, hematological, biochemical, serological parameters, Radiographic analysis and Histopathology of tibiotarsal joints. The antidepressant activity was assessed by Forced swimming test, Rota-rod test and confirmed by estimation of brain neuro transmitters (serotonin and norepinephrine) level. Results of this study revealed that leflunomide and amitriptyline combination showed more significant (p&lt;0.001) antiarthritic and antidepressant action and leflunomide alone treatment showed significant (p&lt;0.001) antiarthritic activity only as compared to arthritic control. The leflunomide and low dose amitriptyline combination found to be more effective in pain associated depression in rheumatoid arthritic rats.

title: Quercetin modulates age-induced changes in the transcript levels of some apoptosis related genes in the skeletal muscles of male rats

description: Adverse changes occur gradually in the skeletal muscles with age via continuous exposure to oxidative stress. Quercetin, a member of the flavonoids family, possesses anti-oxidative and radical-scavenging activities. Therefore, this study investigated the role of quercetin to modulate age-induced changes in the transcript levels of some apoptosis-related genes in rat’s gastrocnemius muscles, up to 15 months-old. Half of the rats at each age (1, 5, 10 and 15 months old) were given a vehicle and the other half was given 200 mg/kg quercetin for 2 weeks, respectively. With the increase of age, vehicle groups showed hyalinization of the muscle fibers and a decrease of the catalase and an increase of the malondialdehyde levels. Down-regulation of Bcl2 gene and up-regulation of both NF-κB and Bax genes were recorded. Interestingly, quercetin groups showed focal hyalinization of the muscle fibers at both 10th and 15th months old. An increase in the catalase and a decrease in malondialdehyde levels, up-regulation of Bcl2 gene and down-regulation of both NF-κB and Bax genes were recorded. In conclusion, quercetin minimized age-induced alteration in the morphological structure and the expression of the apoptosis-related genes via increasing the antioxidant defense in the gastrocnemius muscle.

title: A nanoemulsion-based delivery system for imatinib and in vitro anticancer efficacy

description: A self-nanoemulsifying drug delivery system (SNEDDS) composed of ethyl oleate, Tween 80 and polyethylene glycol 600 was prepared as a new route to improve the efficacy of imatinib. The drug-loaded SNEDDS formed nanodroplets of ethyl oleate stabilized by Tween 80 and polyethylene glycol 600 with a diameter of 81.0±9.5 nm. The nanoemulsion-based delivery system was stable for at least two months, with entrapment efficiency and loading capacity of 16.4±0.1 and 48.3±0.2%, respectively. Imatinib-loaded SNEDDS was evaluated for the drug release profiles, and its effectiveness against MCF-7 cell line was investigated. IC50 values for the imatinib-loaded SNEDDS and an imatinib aqueous solution were 3.1 and 6.5 µg mL-1, respectively.

title: Economic model for obtaining cyclodextrins from commercial cgtase

description: A repetitive batch process was employed followed by membrane ultrafiltration system to produce low-cost cyclodextrins (CDs) using commercial enzymes Toruzyme® cyclomaltodextrin glucanotransferase (CGTase) and its kinetic parameters were determined. The ultrafiltration system enabled the removalof inhibitory products from the reaction medium, allowing the enzyme to be recovered for reuse. A 10 kDa membrane was used to separate the different CDs produced by the CGTase. The substrates evaluated were maltodextrin, corn starch and cassava starch at 5, 10 and 15% (w/V), in the presence and absence of 10% (V/V) ethanol. After reaction for 132 h, 10% (w/V) cassava starch in the presence of ethanol provided the best results with 32.1 mg/mL of β-CD. Maximum production occurred after 72 h of reaction, with a yield of 87.4% of β-CD and an α-CD, β-CD and γ-CD production ratio of 1:1:0.08 g, respectively. When eight repetitive batches of 72 h followed by ultrafiltration and crystallization of β-CD were performed, 2.1 g of precipitate was obtained with a purity of 67.6% β-CD. The supernatant from the crystallization process was lyophilized and resulted in 35.3% α-CD. The developed model can be used industrially for the production of low cost CDs from easily obtained raw material.

title: Paclitaxel and spirulina co-loaded polymeric nanoparticles: in-vitro and in-vivo anticancer study

description: Paclitaxel spirulina nanoparticles were said to have promising anticancer activity against gastric cancer. Nanoparticles of paclitaxel-spirulina were prepared for treating gastric cancer using precipitation technique. The synergistic anticancer efficiency againstMKN45 cells retains when the paclitaxel and spirulina were encapsulated into nanoparticles. To increase the site specific delivery, intra-tumoral administration was carried in the in vivo evaluation. There was an increase in overall survival in an MKN45-transplanted mice model and notable improvement in anti-tumour efficacy when paclitaxel-spirulina nanoparticles were delivered through intra-tumoral administration. The further investigation of overall anticancer mechanism of these nanoparticles is made as a major part in this research. Hence, the conjecture of this research is that, the paclitaxel-spirulina encapsulated nanoparticles could be an effective chemotherapeutic formulation for gastric cancer.

title: Lipid-rich fraction of the sclerotium of Tiger Milk Mushroom Lignosus rhinocerotis (Agaricomycetes) attenuates LPS-induced inflammation in BV2 cells via Nrf2 pathway

description: Lignosus rhinocerotis (tiger milk mushroom) is widely used by the indigenous people of Malaysia as a traditional remedy. The present study was carried out in order to evaluate the antioxidant, cytotoxic and anti-neuroinflammatory activities of L. rhinocerotis extract on brain microglial cells (BV2). The antioxidant activity was evaluated by 2,2-diphenyl-1-picryhydrazyl (DPPH•), 2,2’-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS•+) scavenging assays, and ferric reducing antioxidant power (FRAP). The FRAP, DPPH and ABTS•+ scavenging capacities of the TE3 fraction were 420.77 mg FE/g, 58.01%, and 7%, respectively. The cytotoxic activity was determined by MTS assay. The in vitro model of anti-neuroinflammatory property was evaluated by measuring the production of nitric oxide (NO) in lipopolysaccharide (LPS)-induced BV2 cells. The TE3 fraction showed a significant NO reduction at 1 to 100 µg/mL. The TE3 fraction down-regulated inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX2) genes while it upregulated heme oxygenase (HO-1) and NADPH quinone acceptor oxidoreductase-1 (NQO-1) genes. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) transcription was also activated. The chemical component of the active fraction (TE3) was identified by gas chromatography-mass spectrometry (GCMS). Overall, the BV2 in vitro model anti-neuroinflammatory activity of L. rhinocerotis may be caused by the lipid constituents identified in the fraction.
