Using Boron Supplementation in Cancer Prevention and Treatment: A Review Article

Cancer is a multistage and multifactorial process in which genetic and environmental factors contribute to it. The results of the studies indicate the effective role of micronutrients, vitamins, and minerals in the treatment of malignancies. One of these elements, endorsed by the American Food and Drug Administration, is boron supplements. The present study reviews the role of boron supplementation in the prevention and treatment of cancer. At ISI, Pub Med, Science Direct, Google Scholar, Scopus, Iranmedex and Magiran  databases, we examined 41 studies conducted in the years 1988-2018 regarding the effect of boron supplementation on cancer. The results showed that boron supplement is a useful and essential ingredient for humans with a daily intake of about 1-3 mg per day. Its rich diets have a significant reduction in the risk of developing a variety of cancers including prostate, breast, cervix and lung, liver, melanoma. The mechanisms by which boron may influence cancer is still unknown, but evidence suggests that boron has antioxidant and anti-inflammatory properties. Proposed mechanisms related to boron activity in cancer cells include inhibition of proteasezonin enzymatic activity, dehydrogenase, mRNA modification, and cell division and induction of apoptosis. Boron-containing compounds indicate promising effects for chemotherapy types of cancer. Its concluded that low levels of boron should be considered as a concern for health, and increasing the consumption of boron with its rich diets should be recognized as a rational and reasonable diet recommendation for the prevention and treatment of cancer, promotion of health and well-being.

Protective effects of boron and vitamin E on ethylene glycol-induced renal crystal calcium deposition in rat

Objectives. Kidney stone disease is a common form of renal disease. Antioxidants, such as vitamin E (Vit E) and boron, are substances that reduce the damage caused by oxidation. Methods. Adult male rats were divided into 5 groups (n=6). In group 1, rats received standard food and water for 28 days (control group); in group 2, standard rodent food and water with 0.75 ethylene glycol/d (dissolved in drinking water) (EG Group); in group 3, similar to group 2, with 3 mg of boron/d (dissolved in water) (EG+B Group); in group 4, similar to group 2, with 200 IU of vitamin E injected intraperitoneally on the fi rst day and the 14th day, (EG+Vit E Group); in group 5, mix of groups 3 and 4, respectively (EG+B+Vit E Group). Results. Kidney sections showed that crystals in the EG group increased signifi cantly in comparison with the control group. Crystal calcium deposition score in groups of EG+B (160), EG+Vit E, and EG+B+Vit E showed a significant decrease compared to EG group. Measurement of the renal tubules area and renal tubular epithelial histological score showed the highest signifi cant dilation in the EG group. Tubular dilation in the EG+B+Vit E group decreased compared to the EG+B and EG+Vit E groups. Conclusions. Efficient effect of boron and Vit E supplements, separately and in combination, has a complimentary effect in protection against the formation of kidney stones, probably by decreasing oxidative stress. � 2016, De Gruyter Open Ltd.

Deep ocean minerals minimize eccentric exercise-induced inflammatory response of rat skeletal muscle.

Background: We have previously shown an accelerated recovery from muscle fatigue in men challenged by prolonged exercise after oral deep ocean minerals (DOM) supplementation. Here, we hypothesized a decrease in eccentric exercise-induced muscle inflammation in rats regularly consuming DOM-containing drinks (hardness 600 mg/L and fructose 11%). Methods: Forty-seven male Sprague Dawley rats were randomized into 4 groups: Control (C, N = 12), Fructose (F, N = 12), Fructose+Exercise (FE, N = 12), and Fructose+Exercise+DOM (FED, N = 11). Since fructose is a commonly used ingredient in beverages, 11% of fructose was added as a vehicle of the study. Soleus muscles of rats were analyzed 24 h after an acute bout of downhill running following 9 weeks of DOM supplementation. Results: Leukocyte infiltration and TNF-a mRNA of muscle in the FE group were 5 times and 4 times greater the F group, respectively, (P eight fold greater than the C group (P < 0.05). The reduced glutathione (GSH) of muscle in the F group was 34% lower than that in the C group (P < 0.05). However, GSH levels were similar for the C and FED groups. Conclusion: Prolonged fructose supplementation modulates inflammatory balance of rat skeletal muscle. The results of the study suggest that DOM can minimize eccentric exercise-induced inflammatory cytokine responses in rat skeletal muscle.This work was supported by grants from Taiwan Yes Corporation, Ministry of Science and Technology (Grant No. 102-2410-H-845-018-MY3), and University of Taipei.

Identifying a Window of Vulnerability during Fetal Development in a Maternal Iron Restriction Model

It is well acknowledged from observations in humans that iron deficiency during pregnancy can be associated with a number of developmental problems in the newborn and developing child. Due to the obvious limitations of human studies, the stage during gestation at which maternal iron deficiency causes an apparent impairment in the offspring remains elusive. In order to begin to understand the time window(s) during pregnancy that is/are especially susceptible to suboptimal iron levels, which may result in negative effects on the development of the fetus, we developed a rat model in which we were able to manipulate and monitor the dietary iron intake during specific stages of pregnancy and analyzed the developing fetuses. We established four different dietary-feeding protocols that were designed to render the fetuses iron deficient at different gestational stages. Based on a functional analysis that employed Auditory Brainstem Response measurements, we found that maternal iron restriction initiated prior to conception and during the first trimester were associated with profound changes in the developing fetus compared to iron restriction initiated later in pregnancy. We also showed that the presence of iron deficiency anemia, low body weight, and changes in core body temperature were not defining factors in the establishment of neural impairment in the rodent offspring

Whole body vibration as a safe exercise training method induces no impaired alterations on rat plasma antioxidant biomarkers

Whole body vibration (WBV) has been regarded as an exercise training method and as a non-pharmacological supportive treatment option appearing to be efficient in chronic disease conditions, such as bone disorders and for cardio-respiratory fitness. Since, data on the safety and efficacy of vibration on oxidative stress parameters are lacking, it was decided to assess the effects of WBV on the plasma antioxidant biomarkers in adult male Wistar rat model. Methods: Male Wistar rats weighing 140–180 g, were divided into control and vibration group. Vibration training consisted of vertical sinusoidal whole body vibration for 8 weeks, followed by blood collection. Results: The vibrated rats weighed more than the control group (135.0 ± 21.0 vs. 157.0 ± 36.0 g,P < 0.048). The plasma Cu and Zn concentrations, vitamin C, uric acid, the activities of antioxidant enzymes, total antioxidant capacity, and malondialdehyde (MDA) levels were similar in the vibration group compared with the controls. The mean of Xantine oxidase level was significantly higher (P = 0.05) in the vibration group. No major difference was observed for selected plasma antioxidant parameters. Discussion: The potential effects of physiological responses of WBV on several physiological systems are without deteriorations concerning plasma antioxidant status
