RESUMO
Vasculogenesis (the process of differentiation of angioblasts toward endothelial cells and de novo formation of crude vascular networks) and angiogenesis (the process of harmonized sprouting and dispersal of new capillaries from previously existing ones) are two fundamentally complementary processes, obligatory for maintaining physiological functioning of vascular system. In clinical practice, however, the later one is of more importance as it guarantees correct embryonic nourishment, accelerates wound healing processes, prevents uncontrolled cell growth and tumorigenesis, contributes in supplying nutritional demand following occlusion of coronary vessels and is in direct relation with development of diabetic retinopathy. Hence, discovery of novel molecules capable of modulating angiogenic events are of great clinical importance. Recent studies have demonstrated multiple angio-regulatory activities for endocannabinoid system modulators and endocannabinoid-like molecules, as well as their metabolizing enzymes. Hence, in present article, we reviewed the regulatory roles of these molecules on angiogenesis and described molecular mechanisms underlying them.

WHAT IS KNOWN AND OBJECTIVES: Present study evaluated the safety profile and efficacy of G-Rup® syrup (100 mg/ml ginger extract plus 150 mg/ml honey) in symptomatic treatment of knee osteoarthritis (OA). METHODS: Patients diagnosed with knee OA were randomly assigned (1:1) to receive either of a 30 ml twice daily regimen of G-Rup® syrup or placebo over a 12-week period. Primary endpoints of the study comprised of an improvement in the joint's stiffness, physical functioning and pain score, assessed by WOMAC questionnaire and the visual analog scale (VAS). Secondary objectives comprised of safety and tolerability of the syrup by patients. RESULTS AND DISCUSSION: The 30 ml twice-daily regimen of G-Rup® syrup was safe and well tolerated by patients. Moreover, in whole studied time points, treatment with G-Rup® syrup could significantly Power the VAS score (p < 0.001) whereas improving WOMAC total score (p < 0.001) and pain (p < 0.001), physical functioning (p < 0.001), and stiffness sub-scores (p = 0.006) compared to the placebo receiving group. WHAT IS NEW AND CONCLUSION: Based on obtained results, the G-Rup® syrup, composed of a combination of honey and ginger, may be a proper supplementary choice, along with routine therapeutic regimens, for improvement of symptomatic treatment of OA.

The goal of the current study was to evaluate the efficiency of a phytotherapeutic intervention consisting of a combination of Nigella sativa and Vitex agnus-castus with citalopram in the control of hot flashes in healthy menopausal women. An 8 week, double-blind, randomized, placebo-controlled study was performed among 46 women aged between 40 and 60 years experiencing an average of more than four hot flashes per day recruited during July 2016 to June 2017. Data on severity of vasomotor symptoms were collected at the end of the eighth week. Herbal medication or placebo capsules were administered once daily in morning. At the end of the 8-week treatment period, analyses of covariance demonstrated the superiority of herbal combination with citalopram over placebo and citalopram for three MENQOL domain scores including vasomotor (p < .001), physical (p = .036), psychosocial (p = .001) but no significant differences were observed in terms of sexual function (p = .231). Based on the results, the addition of a combination of N. sativa and V. agnus-castus to the citalopram may be a potential clinical application for improving therapeutic outcomes. Larger randomized, controlled trials are also warranted for further investigations of these symptoms.

This research investigated the preventive effects of myrtenol (MYR), fatty acid nanocarriers (FANC), and myrtenol-loaded FANC (MYR + FANC) on neurological disturbance, stroke volume, the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and tumor necrosis factor-alpha (TNF-α) in the brain with ischemia-reperfusion injuries induced by middle cerebral artery occlusion (MCAO) in rats. Seventy two Wistar male rats were divided into six main groups. The groups were sham, ischemia-reperfusion group (MACO), MACO-MYR (50 mg/kg), MACO-FANC (50 and 100 mg/kg), and MACO-MYR + FANC (50 mg/kg). Stroke volume, neurological deficit scores, and the brain levels of MDA, SOD, and TNF-α were examined with TTC staining, observation, and ELISA, respectively. Pretreatment with MYR, FANC (100 mg/kg), and MYR + FANC reduced the neurological deficit score and cerebral infarction volume. MYR, FANC (100 mg/kg), and MYR + FANC pretreatment increased and decreased brain SOD and MDA levels compared to MACO group, respectively. The TNF-α level decreased in the MYR + FANC group compared to MCAO and MCAO-MYR groups in the brain. The use of FANC (100 mg/kg), MYR, and MYR + FANC has protective effects against oxidative stress and ischemia-reperfusion injury. FANC probably improve the bioavailability of MYR, as MYR+ FANC had more therapeutic effects on the reduction of ischemia-reperfusion injuries, inflammation, and oxidative stress.

The current study aimed to evaluate the safety profile and efficacy of a cannabis-based sublingual spray, CBDEX10® (containing 100 µg cannabidiol and 10 µg Δ9-tetrahydrocannabinol per puff; CBD/Δ9-THC 10:1), in improving lipid profile and glycemic state of the diabetic patients. Fifty diabetic patients were randomly allocated to the treatment (n = 25; receiving two puffs of CBDEX10® twice daily) or the control groups (n = 25; receiving two puffs of placebo). The primary endpoint of the study was to evaluate the efficacy of the CBDEX10® adjunctive therapy in improving the lipid profile and glycemic state of diabetic patients; the secondary endpoint was to assess the safety profile and tolerability of the spray. A statistically significant decline in total cholesterol [estimated treatment difference (ETD) = -19.73 mg/dL; P < 0.05], triglyceride (ETD = -27.84 mg/dL; P < 0.01), LDL-C (ETD = -5.37 mg/dL; P < 0.01), FBS (ETD = -12 mg/dL; P < 0.01), Hb A1C (ETD = -0.21 mg/dL; P < 0.01) and insulin secretion (ETD = -5.21 mIU/L; P < 0.01) was observable in the patients treated with CBDEX10® at the end of the 8-week treatment period. Regarding safety, the mentioned adjunctive regimen was well, and there were no serious or severe adverse effects. Overall, CBDEX1® sublingual spray could be a new therapeutic agent for lipid and glycemic control in diabetic patients.
RESUMO
Cabergoline is routinely prescribed in the management of prolactin excreting adenomas and is associated with low risk of congenital malformations and teratogenicity. Here, we reported the case of a bilateral simple syndactyly in a toddler with maternal exposure to cabergoline during the pregnancy. This association has not been previously described before.
RESUMO
In this study, we reported the design and fabrication of starch/gelatin/graphene oxide biodegradable nanocomposite films with proper potential for food packaging applications. The experiments were designed using Design Expert software via RSM by defining gelatin/starch weight ratio (G/S wt. ratio) and graphene oxide (GO) wt.% as process parameters affecting on the properties of the prepared films. The optimization was done and various properties of the optimum film were investigated. The XRD and SEM images confirmed that GO layers could intercalate in the starch/gelatin matrix and proper dispersion of nanofillers in the matrix obtained via solution casting method. The mechanical strength, thermal stability, surface hydrophilicity, and water vapor permeability were improved in the present of GO which could be related to reinforcing effect and proper barrier property of GO. Degradation of the prepared films under the soil was investigated during 6 weeks and the results indicated at least 30% weight loss happened throughout the test duration. Overall, the obtained results corroborate that the starch/gelatin/GO compounding can be a good candidate for fabricating of biodegradable nanocomposite films for food packaging applications.

Surfactants are often used to create low or "ultralow" oil-water interfacial tensions (IFTs). These molecules, in some cases, may also lead to the inadvertent formation of microemulsion phases which can obscure IFT measurements. Here, we present a case study of such an issue. We also introduce a little-known micropipette technique which has many advantages over the more common spinning drop method for determining low/ultralow IFTs.
