Although many policosanols from different sources, such as sugar cane, rice bran, and insects, have been marketed worldwide, there has been no comparative study of the in vivo efficacy using a hyperlipidemic animal model. This study compared the efficacy of treating dyslipidemia with four different policosanols, including one sugar cane wax alcohol from Cuba (Raydel®) and three policosanols from China (Xi’an Natural sugar cane, Xi’an Realin sugar cane, and Shaanxi rice bran) in hyperlipidemic zebrafish. After 12 weeks of consumption of each policosanol (final 0.1% in diet, wt/wt) and high cholesterol diet (HCD, final 4%, wt/wt) in a tetrabit, the Raydel policosanol group and Xi’an Natural policosanol group showed the highest survivability of approximately 81%, whereas the Xi’an Realin policosanol group and Shaanxi policosanol group showed 57% and 67% survivability, respectively. Among five HCD groups, the Raydel policosanol group showed the lowest serum total cholesterol (TC, p<0.001 versus HCD control) and triglyceride (TG, p<0.001 versus HCD control) with the highest percentage of high-density lipoproteins (HDL)-C in TC. The Raydel policosanol group also showed the lowest serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels with the least infiltration of inflammatory cells and interleukin-6 production in hepatocytes. In the ovary, the Raydel policosanol group also showed the highest contents of mature vitellogenic oocytes with the lowest production of reactive oxygen species and cellular apoptosis in ovarian cells. In the testis, the Raydel policosanol group also showed the healthiest morphology for spermatogenesis with the least interstitial area and reactive oxygen species (ROS) production in testicular cells. In conclusion, 12 weeks of Raydel policosanol consumption resulted in remarkable improvement of the blood lipid profile, amelioration of inflammation in the liver, and enhancement of the cell morphology in the ovary and testis with the highest survivability under the HCD.

The Relationship between Association between Blood Pressure and Risk of Cancer Development

Background of the Study: We investigated the link between hypertension and cancer since it has been suggested that hypertension may raise the long-term risk of cancer. Previous large observational cohort studies found that greater blood pressure (BP) was related to a higher risk of cancer. Mendelian randomization (MR) was utilized to produce less confounded blood pressure estimates (BP) on overall and site-specific malignancies. The study aims to draw conclusions on the relationship between high blood pressure and cancer. Methods: Studies on high blood pressure and various malignancies are inconclusive, except for renal cell carcinoma. However, given that most meta-analyses only contained a limited number of trials, some relative risks had small to moderate magnitudes, and several may have been impacted by residual confounding, careful interpretation is necessary. The study was conducted using the meta-analysis technique. Cochran's Q test and I2 test were used to assess statistical heterogeneity between studies in the current investigation for research involving two or more cause and outcome combinations. Results: Positive correlations were also reported between high blood pressure and esophageal adenocarcinoma, squamous cell carcinoma, liver, and squamous cell carcinoma. However, most studies lacked multivariable adjustments. Physical and numerical risk of cardiovascular disease is linked to bowel cancer but no other cancers. According to a meta-analysis, hypertensive persons could also be at increased danger of gastrointestinal and breast cancer. Most meta-analyses comprised several trials with moderate or mild hazard ratios.ConclusionDifferent types of cancers have been noted to be directly caused by hypertension. In addition, some treatments have also been associated with the side effects of cancer treatments to cause hypertension. Women facing hypertension have an increased risk of getting breast cancer. Although some cancers showed a real relationship with hypertension, others had no connection at all.

Response of Chlorophyllase and Magnesium Dechelatase Enzymes in Yellow and Green‐Fleshed Kiwifruit to Degreening at Different Temperatures

Angeli Labra, Juan Pablo Zoffoli.

Subject: Biology And Life Sciences, Agricultural Science And Agronomy Keywords: flesh color; enzyme activity; high temperature; chlorophyll breakdown

The kiwifruit cultivars include fruit having a diversity of flesh colors in the range red to yellow to green, associated with specific pigment accumulations. In the yellow-fleshed cultivars, chlorophyll degradation is necessary to unmask the underlying carotenoid pigments, which are responsible for the yellow color. This study aimed to conform the enzymatic activity involved in chlorophyll degradation using different degreening temperatures in the yellow-fleshed kiwifruit (cv. ‘Kiss,’ Actinidia chinensis var. chinensis) and in the contrasting green-flesh kiwifruit (cv. ‘Hayward’, Actinidia chinensis var. deliciosa). ‘Kiss’ was harvested at hue angle 106.9 ° and degreening was carried out at 0, 5, 10 or 15 °C for 41 d. Additionally, one week later, a second batch of kiwifruit was subsequently treated at 30 °C for one week to explore the inhibitory effect on degreening and to elucidate the roles of chlorophyllase and magnesium dechelatase enzymes in the process. Fruit degreened at 30 °C was maintained at 15°C for 23 d afterward and was compared with fruit stored at 0 °C or at 15 °C for 30 d. Similar degreening treatments were applied to cv. ‘Hayward’ at commercial maturity. Every seven days, flesh color, pigment concentrations and the activities of chlorophyllase and magnesium dechelatase in the flesh were evaluated. Degreening of ‘Kiss’ kiwifruit was enhanced by the 15 °C treatment or by 30 °C treatment for seven days and was associated with increasing of carotenoids and decreasing of chlorophyll a. The magnesium dechelatase activity was greater in fruit degreening at 15°C, which was consistently maintained throughout the degreening period; however, the activity remained low at very high temperature (30 °C). Regardless of the above, degreening at 30 °C was not inhibited, showing faster color change and high chlorophyllase activity during the exposure time. In contrast, ‘Hayward’ maintained its green color with high concentrations of the chlorophylls and carotenoids. However, the high chlorophyllase and the low magnesium dechelatase activities found in ‘Hayward’, suggest the chlorophyllase enzymes are not the only ones involved in flesh degreening.

(1) Background: Lifestyle changes, eventually associated with a nutraceutical, are recommended strategies for managing high-normal blood pressure (BP) patients with low-moderate cardiovascu-lar (CV) risk. Nitrates-enriched products (i.e., red beet extracts) may help reduce BP, exerting vas-oactive properties and enhancing adherence to lifestyle advice. Our study aimed to evaluate the effectiveness in clinical practice of generic written lifestyle advice and a beetroot-based nutraceu-tical prescription based on the 2018 ESC/ESH guidelines on 24-hour BP in a population with high-normal BP and low-moderate CV risk.; (2) Methods: A longitudinal observational study was con-ducted in two ESH hypertension excellence centres on 43 consecutive subjects with high-normal BP based on repeated office BP (OBP) measurements and a low-moderate CV risk. Twenty-four-hour ambulatory BP monitoring (ABPM) was carried out at baseline and three months after ge-neric written ESC/ESH advice for lifestyle changes associated with a nutraceutical containing 500 mg of dry beetroot extract; (3) Results: Mean age 50±11 years, 54% males, 58% overweight/obese, mean OBP 135±3/85±3 mmHg. At baseline, 24-hour BP, daytime BP and night-time BP were 127±7/80±6 mmHg, 131±8/83±6 mmHg and 118±8/70±5 mmHg, respectively, BP profiles compat-ible with hypertension status in some subjects. After a median follow-up of 98 (92-121) days, all BPs, except night-time diastolic BP, were significantly decreased: -3±6/-2±4 mmHg for 24-hour BP, -3.9±6.0/-3.0±4.0 mmHg for daytime BP and -3.3±7.4/-1.3±4.7 mmHg for night-time BP, respec-tively. No significant clinical changes in weight were detected. BP decreased independently of baseline BP level, gender, smoking status and BMI, while a more substantial decrease in BP was observed in older patients; (4) Conclusions: Our pilot study shows for the first time that written generic lifestyle advice based on ESC/ESH hypertension guidelines coupled with a beetroot-based nutraceutical may represent a valid initial non-pharmacological approach in subjects with high-normal BP and low-moderate CV risk even without personalized diet interventions.
