If you could, you might hire an army to defend your skin against all the assaults it has to deal with day in and day out: pollution, stress, smoke and less-than-healthy foods, to name just a few. Luckily, you can think of antioxidants like vitamin E as your skin’s own battalion.
Are there any ways to treat or even prevent chapped skin naturally? Of course! Over the years I’ve learned what works—and what doesn’t—for protecting little chins, cheeks, and noses from the dry winter air. Here are the best ways to prevent, and in some cases treat, irritated facial skin in winter.
Looking into the future we know that palm oil is here to stay. Palm oil is a superior vegetable oil when done right. It brings functional benefits to markets and economic progress to producing countries, so it has the capacity to bring benefits to many. But it is up to all of us to decide what the future for palm oil will look like. We can create a bright tomorrow when we make the right choices.
It seems that humankind has been in search of cures for heart diseases for as long as medical science existed. The phenomenon was said to have first reared its ugly head in the 1920s and 1930s, when physicians across Britain and the United States were alerted that an uncommon disease was quickly becoming a leading cause of death.
Atherosclerosis is a major cardiovascular disease and one of the commonest causes of mortality in the world. Speech, balance, fine motor control and cognition are affected by atherosclerosis of cerebellar arteries. This study investigated the protective role of vitamin E against induced atherosclerosis in the rabbit cerebellum.
The aim of the study to develop surface modified targeted moiety α-tocopherol (α-t) encapsulated with 5-fluorouracil (5-FU)-poly-D, L-lactic-co-glycolic acid nanoparticles (PLGA NPs) toward the anticancer activity against oral squamous cell carcinoma (OSCC).
MATERIALS AND METHODS:
5-FU was conjugated with the polymer, PLGA by ionic cross-linking and α-tocopherol use as a functionalized surface moiety. Characterization, drug entrapment efficiency, and in-vitro drug release system were optimized at different pH 7.4 and pH 4.5. The in-vitro cell was performed to optimize the anticancer activity through MTT assay and apoptotic staining assay was also performed by flow cytometry to evaluate the cellular apoptotic activity and cellular uptake.
The particle size was distributed within an average range of 145-162 nm, the polydispersity index values lie 0.16-0.30, and the surface charge was at the negative side, -17mV to -23mV. The in vitro drug release system showed more sympathetic situation at pH 7.4 as compared to pH 4.5, for targeted NPs, approximately 86% and 69%, respectively. The non-targeted 5-FU-PLGA NPs showed drug release of 83% and 64% at pH 7.4 and 4.5 subsequently. In vitro anticancer activity confirmed the intense inhibition by α-t-FU-PLGA NPs of 79.98% after 96 h treatment of SCC15 cells and confirmed the steady-state inhibition of 83.74% after 160 h incubation in comparison to 5-FU-PLGA NPs. Subsequently, the early apoptosis, 27.98%, and 16.45%, and late apoptosis, 47.29%, and 32.57%, suggested the higher apoptosis rate in targeted NPs against OSCC.
The surface modified α-t-FU-PLGA NP was treated over SCC15 cells, and the oral cancer cells have shown the high intensity of cellular uptake, which confirmed that the target moiety has successfully invaded over the surface of cancer cells and shown advanced targeted delivery against OSCC.
Tocotrienols (TTs) are vitamin E derivatives naturally occurring in several plants and vegetable oils. Like Tocopherols (TPs), they comprise four isoforms, α, β, γ and δ, but unlike TPs, they present an unsaturated isoprenoid chain. Recent studies indicate that TTs provide important health benefits, including neuroprotective, anti-inflammatory, anti-oxidant, cholesterol lowering and immunomodulatory effects. Moreover, they have been found to possess unique anti-cancer properties.
The purpose of this review is to present an overview of the state of the art of TTs role in cancer prevention and treatment, as well as to describe recent patents proposing new methods for TTs isolation, chemical modification and use in cancer prevention and/or therapy.
Recent literature and patents focusing on TTs anti-cancer applications have been identified and reviewed, with special regard to their scientific impact and novelty.
TTs have demonstrated significant anti-cancer activity in multiple tumor types, both in vitro and in vivo. Furthermore, they have shown synergistic effects when given in combination with standard anti-cancer agents or other anti-tumor natural compounds. Finally, new purification processes and transgenic sources have been designed in order to improve TTs production, and novel TTs formulations and synthetic derivatives have been developed to enhance their solubility and bioavailability.
The promising anti-cancer effects shown by TTs in several preclinical studies may open new opportunities for therapeutic interventions in different tumors. Thus, clinical trials aimed at confirming TTs chemopreventive and tumor-suppressing activity, particularly in combination with standard therapies, are urgently needed.
Malignant mesothelioma (MM) is an aggressive cancer with poor prognosis. We focused on the anticancer activity of tocotrienol (T3) and have reported that a new redox-inactive T3 derivative (6-O-carboxypropyl-α-tocotrienol; T3E) exerts stronger inhibitory effects on MM cell growth than that of T3 in vitro. Furthermore, we have revealed some mechanisms of T3E that are involved in anti-MM effects. However, the effect of T3E in vivo remains unclear. In this study, we compared the plasma concentrations of T3E to that of T3 using mice to clarify differences in pharmacokinetics. Blood was sequentially collected after oral administration of T3 or T3E, and plasma concentrations were analyzed by HPLC. The area under the plasma T3 and T3E concentration-time curve from 0 to 24 h (AUC0-24 h) of T3E was two times higher than that of T3. In addition, we evaluated the effect of T3E oral administration on tumor growth using a xenograft model of mice that were transplanted with human MM cells (H2052 cell line). Tumor volume was significantly reduced without body weight loss in mice orally administered 150 mg/kg T3E once per 2 d for 10 d, which suggests that T3E has potential anti-MM effects.
This study evaluated if vitamin E consumption affects gut microbiota. Mice were grouped into control, low vitamin E (LV), and high vitamin E (HV). LV and HV were fed DL-α-tocopherol at 0.06 mg/20 g and 0.18 mg/20 g of body weight per day, respectively, for 34 days. Body weight of mice was measured before and after vitamin E treatment. Animals were sacrificed, liver, spleen, small intestine and large intestine collected, and weight and length were measured. Composition of gut microbiota was determined by microbiome analysis. Spleen weight index of LV was the highest. However, liver weight indices and intestinal lengths were not different. Body weights of LV group were higher than those of control. Ratio of Firmicutes to Bacteroidetes was different in LV compared to control and HV. These results indicate that low-level consumption of vitamin E increases spleen and body weight, and changes gut microbiota.
Throughout the body, vitamins serve crucial functions to maintain cells in a state of health. Perhaps unimaginatively named for the letters of the alphabet, the vitamins are A, B, C, D and E. Vitamin K breaks the order but is no less important. A recent conversation with a fellow veterinarian led me to review the function of vitamin E in animals and I thought I would share what I learned. Vitamin E in animals serves as an antioxidant in conjunction with the mineral selenium. Routine cell functions that use energy to move molecules around generate a great deal of waste.
