Role of gut microbiota in metabolic syndrome: a review of recent evidence.

The metabolic syndrome is a complex entity comprised of multiple cardiovascular risk factors grouped in a single individual, contributing to an increased rate of cardiovascular events which goes beyond what would be expected given the impact of each individual risk factor. It is a multifactorial condition whose complete pathogenesis is not yet fully understood. Several studies have shown that not only the intestinal microbiota and dysbiosis may play a role in its pathogenesis, but also that modulating said microbiota may play a role in treating or at least ameliorating the metabolic syndrome.

Superparamagnetic Iron Oxide Nanoparticles and Essential Oils: A New Tool for Biological Applications.

Carrageenan from red algae: an application in the development of inhalable tuberculosis therapy targeting the macrophages.

Macrophages have unique surface receptors that might recognize preferentially several moieties present on the surface of infecting organisms, including in the bacterial cell wall. Benefiting from a similar composition regarding the referred moieties, polysaccharides might be good candidates to compose the matrix of drug carriers aimed at macrophage targeting, as they can use the same recognition pathways of the infecting organisms. Carrageenan (CRG), a polysaccharide extracted from red edible seaweed, is an interesting possibility for the approach of directly targeting alveolar macrophages, as its composition is reported to be recognized by several macrophage lectin receptors.

In this work, we describe the production of drug-loaded chondroitin sulphate microparticles by spray-drying, testing the effect of using different solvents during the process. Full characterisation of the polymer and of the aerodynamic properties of the obtained microparticles are provided envisaging an application in inhalable tuberculosis therapy.

Muscle-specific SMN reduction reveals motor neuron-independent disease in spinal muscular atrophy models.

Paucity of the survival motor neuron (SMN) protein triggers the oft-fatal infantile-onset motor neuron disorder, spinal muscular atrophy (SMA). Augmenting the protein is one means of treating SMA and recently led to FDA approval of an intrathecally delivered SMN-enhancing oligonucleotide currently in use. Notwithstanding the advent of this and other therapies for SMA, it is unclear whether the paralysis associated with the disease derives solely from dysfunctional motor neurons that may be efficiently targeted by restricted delivery of SMN-enhancing agents to the nervous system, or stems from broader defects of the motor unit, arguing for systemic SMN repletion.

Effectiveness of nanoemulsions of clove and lemongrass essential oils and their major components against and .

Nanoemulsions exhibit a number of advantages to carry and deliver lipophilic compounds such as essential oils (EOs) due to their good stability and high surface area per volume unit. The purpose of this work was to assess the long-term stability of nanoemulsions of clove and lemongrass (LG) EOs and their principal components eugenol and citral (CI), respectively, at 3 different concentrations (2, 5 or 10 times their respective minimum inhibitory concentrations) and at two storage temperatures (1 °C and 21 °C). The initial droplet size of LG and CI-loaded nanoemulsions was below 100 nm and most of them kept droplet sizes in the nano-range until the end of storage at both temperatures.
