Effect of Flaxseed on TGF-Β, IL-6, and MMP9 Genes Expression during Wound Healing Process in Rabbits

BACKGROUND: Wound healing is a natural restorative response to tissue injury, and it involves regulated order of cellular and biochemical actions to reinstate tissue after injury, which involves resurfacing reconstitution, and restoration of tensile strength of injured skin. Normal and impaired wound healing post-significant problems related to healthcare and expenditure. Most of the chemical medications which widely used for wound healing might cause unwanted side effects with prolonged use such as hyper scarring, thus studies using natural products are now deemed important. Flaxseed is a natural product that enhances the immune system functioning against different diseases. Nevertheless, limited studies have been done looking into the response triggered by immune cells and the wound-healing-related genes with the use of flaxseed extract onto the wounded skin for the healing process. AIM: The main objective of this study is to analyze the expression of wound healing-related genes during different stages of the wound healing process induced by flaxseed in vivo. METHODS: The effect of flaxseed oil in the early stages (day 4 and 7) and late stages (day 14) of wound healing was explored on New Zealand white rabbits by creating a longitudinal full thickness wound on their back. The gene expression profiles of transforming growth factor-beta (TGF-β), IL-6, and metalloproteinase (MMP9) genes which have roles in wound healing through inflammation, proliferation, and remodeling were studied by polymerase chain reaction method. RESULTS: Flaxseed extract has significant effects in up-regulating anti-inflammatory marker TGF-β in wounds. Flaxseed oil also reduces the expression level of MMP9 on day 14 of wound healing. CONCLUSIONS: This suggests that flaxseed extract has the potential to promote wound healing through the regulation of TGF-β and MMP9 in vivo.

Is "Wild" a Food Quality Attribute? Heavy Metal Content in Wild and Cultivated Sea Buckthorn and Consumers' Risk Perception

Globally, the consumption of herbal supplements is on an upward trend. As the food supplement industry thrives, so does the need for consumers’ awareness of health risks. This contribution is grounded on two assumptions. Firstly, not always “wild” is a food quality attribute, and secondly, the food chain is judged as a noteworthy route for human exposure to soil contamination. Sea buckthorn (SBT) was selected for investigation due to its versatility. In addition to its wide therapeutic uses, it is present in ecological rehabilitation which may raise concerns regarding its safety for human consumption as a consequence of the accumulation of contaminants in the plant. The study aims to discover if the objective contamination of SBT with toxic residues is congruent with people’s subjective evaluation of SBT consumption risk. A quantitative determination of heavy metals was performed by atomic absorption spectrometry. The metals abundance followed the sequence Fe > Cu > Zn > Mn > Cr > Ni > Pb > Cd. Quantitative data on consumers’ subjective risk evaluations were collected through an online survey on 408 Romanians. Binary logistic shows that the consumption of SBT is predicted by the perceived effect of SBT consumption on respondents’ health. The study confirms that the objective contamination of wild and cultivated SBT is in line with the perceived contamination risk. It is inferred that a joint effort of marketers, media, physicians, and pharmacists is needed to inform consumers about the risks and benefits of SBT consumption.

Cationic liposomes mediated transdermal delivery of meloxicam and ketoprofen: Optimization of the composition, in vitro and in vivo assessment of efficiency

New liposomes modified with pyrrolidinium surfactants containing a hydroxyethyl fragment (C_nPB, n = 12, 14, 16) were prepared for transdermal delivery of non-steroidal anti-inflammatory drugs. In order to obtain the optimal composition, the surfactant/lipid molar ratio (0.02/1; 0.029/1; 0.04/1) and the amphiphile hydrocarbon tail length were varied. Rhodamine B was loaded in all formulations, while meloxicam and ketoprofen in selected ones. For liposomes studied the hydrodynamic diameter was in the range of 80-130 nm, the zeta potential ranged from +35 to +50 mV, EE was 75-99%. Liposome modification leads to a prolonged release of the rhodamine B (up to 10-12 h) and faster release of non-steroidal drugs (up to 7-8 h) in vitro. The ability to cross the skin barrier using Franz cells was investigated for liposomal meloxicam and ketoprofen. The total amount of meloxicam and ketoprofen passed through the Strat-M® membranes during 51 h was 51-114 μg/cm² and 87-105 μg/cm² respectively. The evaluation of transdermal diffusion ex vivo showed that total amount of liposomal ketoprofen passed through the skin during 51 h was 140-162 μg/cm². Liposomes modified with C₁₆PB were found as the most effective inflammation reducing formulation in the carrageenan edema model of rat paw.

Topical treatment of radiation-induced dermatitis: current issues and potential solutions

Approximately 95% of patients receiving radiotherapy (RT) will ultimately develop radiation-induced dermatitis (RID) during or after the course of treatment, with major consequences on quality of life and treatment outcomes. This paper reviews the pathophysiology of RID and currently used topical products for the prevention and treatment of RID. Although there is no consensus on the appropriate management, recent evidence suggests that the use of topical products supports to protect and promote tissue repair in patients with RID. Basic recommendations include advice to wear loose clothing, using electric razors if necessary, and avoiding cosmetic products, sun exposure or extreme temperatures. Based on mechanisms involved and on the clinical characteristics of oncological patients, the profile of the ideal topical product for addressing RID can be designed; it should have limited risk of adverse events, systemic adsorption and drug–drug interactions, should be characterized by multiple clinical activities, with a special focus on localized pain, and should have a careful formulation as some vehicles can block the RT beam.

New Insights on Unique Features and Role of Nanostructured Materials in Cosmetics

The cosmetics industry has boomed in recent years as one of the markets that holds enormous growth potential. Among several industrial sectors, the cosmetics industry has considered nanotechnology-based principles and implemented in product management practices. Out of 1000 registered products available on the global market, up to 13% were referred to as products for cosmetic use. A large number of nanoscale materials with unique physicochemical properties are currently being used in the cosmetics formulations or recommended for future use as nano-systems or novel nanocarriers to encapsulate active ingredients for their efficient delivery through the skin barriers. These nano-systems have demonstrated potential in targeted-oriented drug delivery and offered remarkable features such as better stability, site-specificity, excellent encapsulation efficiency, prolonged action, enhanced skin penetration, and high drug-loading capability. Nevertheless, nanotoxicology research has raised concerns over the excessive use of nanomaterials/nanoparticles in cosmetics, as nanoparticles might enter the skin resulting in health problems. This review provides insights on the characteristic physicochemical features and the potential use of various nanostructured materials, including liposomes, noisome, nanoemulsions, nanoparticles, carbon nanomaterials (graphene, fullerenes), carbon nanotubes, dendrimers, and nanospheres in cosmeceuticals. Moreover, the regulatory aspects of nanomaterials in cosmetics, along with concluding remarks and outlook in this field, were also vetted.
