Neuroprotective effect of Portulaca oleracea extracts against 6-hydroxydopamine-induced lesion of dopaminergic neurons.

The Portulaca oleracea L. (Portulacaceae) is a cosmopolitan species with a wide range of biological activities, including antioxidant and neuroprotective actions. We investigated the effects of P.

The Effect of Alpinia zerumbet Essential Oil on Post-Stroke Muscle Spasticity.

The essential oil of Alpinia zerumbet (EOAz) presents myorelaxant and antispasmodic actions on cardiac and smooth muscles. The aim of this study was to investigate the effect of EOAz on the skeletal muscle contraction in post-stroke spasticity. Fifteen adults with unilateral hemiparesis and spasticity resulting from stroke were submitted to surface electromyography readings of the gastrocnemius muscle, before and after 10 daily applications (dermal 0.

Human dental pulp stem cell behavior using natural nanotolith/bacterial cellulose scaffolds for regenerative medicine.

Adhesion and Viability study with human dental pulp stem cell using natural nanotolith/bacterial cellulose scaffolds for regenerative medicine are presented at first time in this work. Nanotolith, are osteoinductors, i.e.

Plants with anti-Leishmania activity: Integrative review from 2000 to 2011.

The search for more effective new drugs to treat Leishmaniasis is undoubtedly relevant. Our objective in this study was to investigate research publications addressing plants with anti-Leishmaniasis activity. An integrative review of the literature from 2000 to 2011 was carried out in the databases such as Latin-American and Caribbean Health Sciences (LILACS), Scientific Electronic Library Online (SciELO), and Medical Literature Analysis and Retrieval System Online (MEDLINE).

Novel electrospun nanotholits/PHB scaffolds for bone tissue regeneration.

Nanotholits is an osteoinductor or be, stimulates the bone regeneration, enabling bigger migration of the cells for formation of the bone tissue regeneration mainly because nanotholits are rich in minerals considered essential to the bone mineralization process on a protein matrix (otolin) as hydroxiapatite. In order to improve its biodegrability and bioresorption in new platforms for tissue engineering, it was electrospun PHB/nanotholits from aqueous solutions of this polymer at concentrations of nanotholits 1% (w/v) and compared morphological and thermal properties with PHB/nanotholits casting films. Electrospun PHB/nanotholits mats presents more symmetric nanopore structure than casting films mats observed by SEM images mainly because the orientation of pores along the longitudinal direction of the electrospun fibers.

Brazilian solar saltworks - ancient uses and future possibilities.

Coastal solar saltworks of Brazil are exploited for sea salt, which becomes progressively concentrated by evaporation. This study aimed to review the current and new potential uses of these systems, in order to provide more dynamic for this activity. The first evaporation ponds are also used for artisanal fisheries, ensuring the livelihood of many families.

Antimicrobial activity of broth fermented with kefir grains.

Kefir grains originate from the Caucasus region and are used for preparing beverages using sugar solution, milk, and fruit juice. As long as they are formed by a microbial consortium useful in the intestine, the produced drinks can be called probiotics. The aim of this study was to determine the antimicrobial activity during kefir fermentation in sugar broth.
