Experimental and clinical studies evidenced the health effects of moderate consumption of beer, mainly due to the presence of bioactive compounds, such as polyphenols, vitamins, or fibers. To exploit the potential beneficial effect on health and in disease prevention of these compounds, a new beverage based on barley malts and hops named Aliophen® has been designed, through a patented production process, with a high total polyphenolic amount compared to alcohol-free beer and similar to the one present in light and dark beers. In the present study, the antioxidant activity of Aliophen® against low-density lipoprotein (LDL) oxidation and its ability to protect erythrocytes from hemolysis have been characterized. Moreover, the chemopreventive effect of Aliophen® against colon cancer has been assessed, employing a mouse model of chemically induced carcinogenesis using azoxymethane (AOM). Data obtained showed that Aliophen at a low dose (3 mg/kg) inhibited the formation of preneoplastic lesions, polyps, and tumors. At higher doses (300 mg/kg) the protective effect was measured in the first phase of the onset of cancer. The antioxidant properties of Aliophen® were also observed in AOM-treated mice where it increased the serum antioxidant capacity. Based on the data presented, Aliophen® can exert promising health effects, including an anticancer capacity presumably associated with its antioxidant properties.

Effective Antioxidant

The hydroxycinnamates, intermediates in the phenylpropanoid synthetic pathway, are effective in enhancing the resistance of low-density lipoprotein (LDL) to oxidation in the order caffeic acid > ferulic acid > p-coumaric acid. It is unclear whether the mode of action of ferulic acid as an antioxidant is based on its activities in the aqueous or the lipophilic phase. Partitioning of 14C-labelled ferulic acid into plasma and its components, LDL and the albumin-rich fractions, has been studied under conditions of maximum aqueous solubility. The majority of ferulic acid associates with the albumin-rich fraction of the plasma, although a proportion is also found to partition between the LDL and aqueous phases; however, ferulic acid does not associate with the lipid portion of the LDL particle, suggesting that it exerts its antioxidant properties from the aqueous phase. This is of particular interest since the results demonstrate that ferulic acid is a more effective antioxidant against LDL oxidation than the hydrophilic antioxidant ascorbic acid.

Coumaric Acid

Mechanisms in which p-coumaric acid (CA) acts as an antioxidant are not well understood. This study investigated whether CA can act as a direct scavenger of reactive oxygen species (ROS) and whether it minimizes the oxidation of low-density lipoprotein (LDL). Rats were administered CA in drinking water at low or high doses for 10, 21, and 30 days (uptakes were 29 and 317 mg/day, respectively). Blood levels of 8-epiprostaglandin F2αwere monitored as a marker of LDL oxidation. Oral administration of CA (317 mg/day) for 30 days significantly inhibited LDL oxidation. CA also reduced LDL cholesterol levels in serum but had no effect on levels of high-density lipoprotein cholesterol. In vitro studies that used electron spin resonance in combination with spin trapping techniques were used to determine the ability of CA to scavenge ROS and alter LDL oxidation. CA effectively scavenged ·OH in a dose-dependent manner. IC50and maximum velocity for CA scavenging of ·OH were 4.72 μM and 1.2 μM/s, respectively, with a rate constant of 1.8 × 1011M−1· s−1. Our studies suggest that the antioxidant properties of CA may involve the direct scavenging of ROS such as ·OH.

Small dense low-density lipoprotein (sdLDL) is an established risk factor in ischemic heart disease. However, its clinical significance in acute ischemic stroke (AIS) is uncertain. This study evaluates the prognostic value of the presence of sdLDL in patients with AIS by determining whether it contributes to clinical outcome or not. We studied 530 consecutive patients admitted within the first 48 hours after onset of ischemic stroke and 50 corresponding controls. Serum lipid parameters were measured on admission by standard laboratory methods. The percentage of AIS patients with sdLDL was significantly higher than the one of matched controls with sdLDL. Concerning comparisons between AIS patients with or without sdLDL, the percentages of males and patients with histories of smoking, hypertension, and cardiovascular disease were significantly higher in AIS patients with sdLDL. Concerning the grade of severity, modified Rankin Scale (mRS) on discharge was significantly higher in AIS patients with sdLDL. On logistic regression analysis, age (OR=2.29, P3). Our study showed that the presence of sdLDL might be independently associated with a poor prognosis after AIS.

Mitotane is widely used for the treatment of adrenocortical cancer (ACC), although the drug-related toxicity complicates its use. The aim of this study is to assess comprehensively the different endocrine and metabolic unwanted effects of the drug, and to provide data on the supportive therapies. We retrospectively analyzed 74 ACC patients adjuvantly treated with mitotane for ≥12 months. During the treatment period (40 months, 12–195), 32.4% of patients needed replacement therapy for mineralocorticoid deficit, 36.2% for hypothyroidism and 34.3% for male hypogonadism. In fertile women, hypogonadism was uncommon, while 65.4% of women developed ovarian cysts. Although no significant change in low-density lipoprotein (LDL) was observed, statins were started in 50% of patients for a significant increase in total cholesterol and triglycerides. Dyslipidemia occurred early, after a median time of 6 months from mitotane start. Conversely, testosterone replacement was usually started after >2 years. In many cases, ranging from 29.4% to 50% according to the side effect, toxicity occurred well before the achievement of the target mitotane concentrations. Supportive therapies were able to revert the biochemical alterations induced by mitotane, although higher doses were needed for a likely pharmacokinetic interaction of exogenous steroids and statins with mitotane. In conclusion, adjuvant mitotane therapy is associated with a spectrum of unwanted effects encompassing the function of different endocrine glands and requires a careful clinical and biochemical assessment associated with the therapeutic drug monitoring.

The goal of this research is to analyze the change of students’ physical health during the one year of studies in context of lifestyle. The research participants were 103 Medical College’s students aged 19 to 56 years. All tests, measurements and questionnaires were done at falls of 2015 and 2016. Students’ physical health was evaluated in accordance with Apanasenko’s methods based on investigative anthropometric and functional testing measurements. These measurements included body mass index, lungs vital capacity, strength index, Robinson index and Recovery Heart Rate. Students’ lifestyle habits were determined with the help of questionnaire that included question groups regarding the self-evaluation of health status, health problems and illnesses, eating habits, and physical activities. During the research, lipid parameters in blood were also measured determining the total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL).

Raised total homocysteine (tHcy) levels may be involved in the etiology of cardiovascular disease and can lead to damage of vascular endothelial cells and arterial wall matrix. Folic acid supplementation can help negate these detrimental effects by reducing tHcy. Recent evidence has suggested an additional anti-atherogenic property of folate in protecting lipoproteins against oxidation. This study utilized both an in vitro and in vivo approach. In vitro: Very-low-density lipoprotein (VLDL) and low density lipoprotein (LDL) were isolated by rapid ultracentrifugation and then oxidized in the presence of increasing concentrations (0→ μmol/L) of either folic acid or 5-methyltetrahydrofolate (5-MTHF). In vivo: Twelve female subjects were supplemented with folic acid (1 mg/day), and the pre- and post-VLDL and LDL isolates subjected to oxidation. In vitro: 5-MTHF, but not folic acid, significantly increased the resistance of VLDL and LDL to oxidation. In vivo: Following folic acid supplementation, tHcy decreased, serum folate increased, and both VLDL and LDL displayed a significant increase in their resistance to oxidation. These results indicated that in vitro, only the active form of folate, 5-MTHF, had antioxidant properties. In vivo results demonstrated that folic acid supplementation reduced tHcy and protected both VLDL and LDL against oxidation. These findings provide further support for the use of folic acid supplements to aid in the prevention of atherosclerosis.
