RESUMEN

OBJECTIVE: Cakile maritima scop. (CKM) is a herbaceous plant (Brassicaceae) growing also in high salinity environment. It is an annual plant growing in clumps or mounds in the sand on beaches and bluffs. MATERIALS AND METHODS: Stems, seeds, leaves and flowers of CKM were used to obtain 70% of ethanol extracts. The phenolic content of the different extracts was evaluated by the Folin-Ciocalteu method. The separation of phytochemical compounds was based on ultra-performance liquid chromatography coupled to mass spectrometry. Radical scavenging activity was determined by 1,1-diphenyl-2-picrylhydrazyl assay. The qualitative assay for the inhibition of α-glucosidase was quantified spectrophotometrically and the anti-inflammatory activity was determined in the U937 cell line by using gene expression of pro-inflammatory cytokines. Cell viability assay was done in U937, MM1S, and U266 cells by using the 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay. The antimicrobial activity was investigated by MIC determination, "double-triple combinations assay", and growth inhibition curves analysis, using the extracts individually or in various combination. Statistical analysis was performed by the Student's t-test and ANOVA. RESULTS: All parts of the plant exhibited a high antioxidant capacity as measured by DPPH assay. Furthermore, all extracts reduced (about 10 folds) the expression of inflammatory cytokines in macrophage following LPS treatment. As regards the antibacterial activity, only the seeds extract was able to inhibit both Gram-negative and Gram-positive bacteria when tested alone, whereas dual combinations of different extracts (leaves, flowers, stems and seeds) caused bacterial inhibition exhibiting a synergic action. Finally, we showed that the extracts did not exhibit cytotoxic effects in normal cells and that, surprisingly, it exhibited an anti-proliferative effect (inhibition ≈80%) in multiple myeloma U266 cells. CONCLUSIONS: Our study suggests that CKM possesses antioxidant, anti-inflammatory, antibacterial, anti-proliferative activities and such pleiotropic effects may be exploited under various pathological conditions.

RESUMEN

OBJECTIVE: Moringa oleifera Lam., a multipurpose tree, is used traditionally for its nutritional and medicinal properties. It has been used for the treatment of a variety of conditions, including inflammation, cancer and metabolic disorders. MATERIALS AND METHODS: We investigated the effect of Moringa oleifera Lam. on adipogenic differentiation of human adipose-derived mesenchymal stem cells and its impact on lipid metabolism and cellular antioxidant systems. RESULTS: We showed that Moringa oleifera Lam. treatment during adipogenic differentiation reduces inflammation, lipid accumulation and induces thermogenesis by activation of uncoupling protein 1 (UCP1), sirtuin 1 (SIRT1), peroxisome proliferator-activated receptor alpha (PPARα), and coactivator 1 alpha (PGC1α). In addition, Moringa oleifera Lam. induces heme oxygenase-1 (HO-1), a well established protective and antioxidant enzyme. Finally Moringa oleifera Lam. significantly decreases the expression of molecules involved in adipogenesis and upregulates the expression of mediators involved in thermogenesis and lipid metabolism. CONCLUSIONS: Our results suggest that Moringa oleifera Lam. may promote the brown remodeling of white adipose tissue inducing thermogenesis and improving metabolic homeostasis.

RESUMEN

The antihypertensive treatments have resulted in favorable effects in terms of cardiovascular morbidity and mortality in the elderly, but the therapeutic approaches raise problems linked to the pathophysiological aspects of hypertensives and to the reduced homoeostatic capacity of the senile organism. The antihypertensive treatment in elderly must be aimed at achieving a maximal improvement in the cardiovascular risk profile with possibly minimal side effects. The first step is the non-pharmacological therapy which is a hygienic-behavioral program aimed at changing the patient's life style (physical exercise, reduced salt intake, body weight control, etc.). Non-pharmacological therapy in the elderly patients requires a preliminary evaluating protocol and a close monitoring of the individual responses. The diet, restriction of sodium intake (4-6 g/day), and aerobic physical exercise are important for decrease the development and persistence of hypertension. The non-pharmacological therapy has a low antihypertensive action, however, once established, it should not be abandoned, as its association with pharmacological treatment allows the use of fewer and lower doses of drugs, with a consequent reduction of the risks due to side effects.

RESUMEN

Sixty-two patients with breast cancer treated with Adriamycin-containing adjuvant chemotherapy developed recurrent disease. Four patients refused to take any form of systemic therapy at the time of relapse. Fifty-eight patients were managed with various treatment modalities, and of these 33 (57%) achieved on objective remission, 11 (19%) had stable disease and 14 patients (24%) did not respond to any form of therapy. Twenty-four patients received more than one treatment modality. Thirty-eight patients were treated with chemotherapy and 35 received endocrine therapy. Eight of 20 patients (40%) achieved objective remission upon retreatment with higher dose of 5-fluorouracil, Adriamycin, and cyclophosphamide at time of relapse, and seven of 18 patients (38%) treated with other chemotherapeutic agents showed objective remission. Fourteen of 35 patients (40%) achieved objective remission with hormonal therapies. The median survival from first relapse was 15 months for all patients, and was 25.7 months for responding patients. Survival was significantly longer in asymptomatic patients compared with those who were symptomatic from recurrent disease.

RESUMEN

A phase II evaluation of anguidine was carried out in 30 patients with advanced refractory breast cancer. A dose of 5.0 mg/m2 daily for 5 days was explored. The main toxic effects were nausea and vomiting, fever and chills, hypotension, skin erythema, somnolence, confusion, and lethargy. Myelosuppression was minimal. Among these extensively pretreated patients, there was one partial responder and one additional patient who showed improvement (less than a partial response); both responses occurred in soft tissue sites.
