Bioactivity of betulinic acid nanoemulsions on skin carcinogenesis in transgenic mice K14E6

Alternative therapies for cancer treatment have been developed using bioactive compounds such as betulinic acid (BA). The objective of this study was to investigate the bioactivity of BA in its free form and compare it with its nano-encapsulated form under a skin carcinogenesis protocol in a genetically modified murine model. K14E6 and FVB mice were divided into four groups to be treated with free BA and with betulinic acid nanoemulsion (BANE). Lecithin enriched with medium chain fatty acids (MCFAs) was employed as an emulsifier to prepare the nanoemulsions with a mean droplet size of 40 nm. Skin tumors were induced by exposure to DMBA and TPA directly to the transgenic mice. Tumor development was completely inhibited by BANE and by 70% with free BA. This was validated by histological sections and the gene expression of the Cdk4 and Casp8 genes.

Gestational Diabetes Mellitus: The Crosslink among Inflammation, Nitroxidative Stress, Intestinal Microbiota and Alternative Therapies

Gestational diabetes mellitus (GDM) is characterized by a set of metabolic complications arising from adaptive failures to the pregnancy period. Estimates point to a prevalence of 3 to 15% of pregnancies. Its etiology includes intrinsic and extrinsic aspects of the progenitress, which may contribute to the pathophysiogenesis of GDM. Recently, researchers have identified that inflammation, oxidative stress, and the gut microbiota participate in the development of the disease, with potentially harmful effects on the health of the maternal-fetal binomial, in the short and long terms. In this context, alternative therapies were investigated from two perspectives: the modulation of the intestinal microbiota, with probiotics and prebiotics, and the use of natural products with antioxidant and anti-inflammatory properties, which may mitigate the endogenous processes of the GDM, favoring the health of the mother and her offspring, and in a future perspective, alleviating this critical public health problem.

Plant-Based Polyphenols: Anti-Helicobacter pylori Effect and Improvement of Gut Microbiota

Helicobacter pylori (H. pylori) infection affects more than half of the world’s population, and thus, about 10 to 20% of people with H. pylori suffer from peptic ulcers, which may ultimately lead to gastric cancer. The increase in antibiotic resistance and susceptibility has encouraged the search for new alternative therapies to eradicate this pathogen. Several plant species are essential sources of polyphenols, and these bioactive compounds have demonstrated health-promoting properties, such as the gut microbiota stimulation, inflammation reduction, and bactericidal effect. Therefore, this review aims to discuss the potential effect of plant-based polyphenols against H. pylori and their role in the gut microbiota improvement.

Homeopathy for the treatment of gastrointestinal disorders in children

Background: Colic and diarrhea are among the most common gastrointestinal disorders in childhood, which manifest spontaneously and acute. The allopathic treatment consists, in most cases, in the administration of the association homatropine-dimethicone to relieve colic, and oral rehydration and loperamide in cases of diarrhea [1,2]. The ineffectiveness of the conventional treatment and the possible adverse effects they may cause have led to increase the demand from children’ parents for complementary and alternative therapies, and homeopathy can be one of the first choices in this disorders [3]. Aims: make a literature review evaluating the effectiveness of homeopathic treatment for colic and diarrhea in children, observing the relation between the main medicines prescribed in these disorders and their pathogenesis described in materia medica. Methodology: a literature research was performed applying electronic database, including Medline, HomeoIndex, BIREME, LILACS, PubMed, SciELO, and ScienceDirect in the period from September to December 2010. Results: Data found indicate that few studies are available in the literature to prove the effectiveness of homeopathic medicines for colic and diarrhea in children, but the applicability of this therapeutic modality seems to be useful, safe and low cost, which are important factors for less favored communities. Besides, studies concerning diarrhea are more frequent, not only because of its gravity, but also for the duration, which makes more adequate the monitoring, on the contrary to acute colic. The most cited medicines were Chamomilla, Nux vomica, Arsenicum album and Mercurius solubilis. Conclusions: Homeopathy can be an important source of colic and diarrhea relief. However, more investigations should be performed in order to show parents how valuable this kind of therapy can be to children and the whole family.

Structure-Based Design of an RNase Chimera for Antimicrobial Therapy

Bacterial resistance to antibiotics urges the development of alternative therapies. Based on the structure-function of antimicrobial members of the RNase A superfamily, we have developed a hybrid enzyme. Within this family, RNase 1 exhibits the highest catalytic activity and the lowest cytotoxicity; in contrast, RNase 3 shows the highest bactericidal action, alas with a reduced catalytic activity. Starting from both parental proteins, we designed a first RNase 3/1-v1 chimera. The construct had a catalytic activity much higher than RNase 3, unfortunately without reaching an equivalent antimicrobial activity. Thus, two new versions were created with improved antimicrobial properties. Both of these versions (RNase 3/1-v2 and -v3) incorporated an antimicrobial loop characteristic of RNase 3, while a flexible RNase 1-specific loop was removed in the latest construct. RNase 3/1-v3 acquired both higher antimicrobial and catalytic activities than previous versions, while retaining the structural determinants for interaction with the RNase inhibitor and displaying non-significant cytotoxicity. Following, we tested the constructs’ ability to eradicate macrophage intracellular infection and observed an enhanced ability in both RNase 3/1-v2 and v3. Interestingly, the inhibition of intracellular infection correlates with the variants’ capacity to induce autophagy. We propose RNase 3/1-v3 chimera as a promising lead for applied therapeutics.

Cell-Penetrating Antimicrobial Peptides Derived from an Atypical Staphylococcal δ-Toxin

The continued emergence and global distribution of infections caused by antimicrobial-resistant pathogens fuel our perpetual need for new or alternative therapies. Here, we present the discovery and initial characterization of bacterial cell-penetrating AMPs that were based on a family of virulence factors.

Gout is a joint disease caused by high uric acid in the blood. Patients with this problem usually experience joint pain, so alternative therapies are needed to reduce pain. Ginger compress the rapyisone of the effective alternative therapies to reducepain, by utilizing warn water and greted ginger. It is paharmacological and non-pharmacological process, to reduce side effects and it is better to use non-pharmacological methods for the best result. This paper aims to find out the implication of applying the method as the alternative way to reduce pain in patientwith gout. A case study of nursing care was chosen as the method. It applied in to two patients with gout. The result stated the therapy has effectively reduced pain in the patients. Thus, it suggested to the nurses forapplying thi therapy.Keywords :gout; pain;compress with ginger AbstrakPenyakit Asam Urat atau penyakit gouta dalah penyakit sendi yang disebabkan oleh tingginya asam urat di dalam darah.
