Abstract
Roselle (Hibiscus sabdariffa L.) is an increasingly attractive plant for its health and pharmaceutical, beverage, and cosmetic applications. The purpose of this study was to investigate the clinical effects of roselle drink on antioxidant activity, blood pressure, and skin condition. Roselle drink used in this study contained rich phenolics (1.96 g of gallic acid equivalent/100 ml) and anthocyanins (1.65 g of cyanidin-3-glucoside equivalent/100 ml). In a randomized, cross-over, double-blind, placebo-controlled clinical study, 39 healthy adults received drank 200 ml of roselle drink or placebo-control drink for 6 months. A significant reduction in the blood pressure was observed in the roselle drink treated group when compared with preintervention values. After 6 months of treatment with roselle drink, serum phenolics contents, the levels of Trolox equivalent antioxidant capacity (TEAC), glutathione, superoxide dismutase (SOD), glucose-6-phosphate dehydrogenase (G-6-PDH), glutathione peroxidase (GSH-Px), and glutathione reductase (GSH-Rd) were significantly increased in healthy subjects. However, a significant increment in skin redness and skin moisture was observed in the facial skin of roselle drink-treated participants. Oral administration of roselle drink for 6 months significantly lowered the blood pressure, improved antioxidation level, and positively regulated skin redness as well as moisture. Phenolics and anthocyanins in roselle could be the major potential contributors to such health effects. PRACTICAL APPLICATIONS: Roselle is a typical plant. Continuous administration of roselle drink clearly improved antioxidation levels, reduced blood pressure and positively regulated skin redness and moisture. Phenloics and anthocyanins in roselle could be the major potentila contributors of such health benefits.

Abstract
BACKGROUND & AIMS Rhus coriaria L. (Sumac) is a popular spice/herb with several biological functions owing to its antioxidant and insulin-like activities. Many clinical trials have indicated the potent anti-diabetic property of sumac but the results on few glycemic indices were inconclusive. Hence, this systematic review and meta-analysis were aimed to investigate sumac supplementation effect on glycemic indices. METHODS Systematically searched was performed by two independent reviewers using online databases including: PubMed, Scopus, web of science, EMBASE from inception until November 2020. Data were pooled using a random-effects model and weighted mean difference (WMD) with 95 % confidence intervals (CI). RESULTS A total of 6 potentially relevant clinical trials met the inclusion criteria with total of 278 participants. Random-effects meta-analysis suggested no significant effects on the levels of fasting blood glucose [-7.08 mg/dl, 95 % CI: -14.85 to 0.70,P = 0.07, I2 = 59.8 %], glycosylated hemoglobin (HbA1c) [-0.48 %, 95 % CI: -1.01 to -0.04, P = 0.07, I2 = 0.0 %], homeostatic model assessment for insulin resistance (HOMA-IR) [-0.97, 95 % CI: -1.96 to 0.02, P = 0.05, I2 = 83.8 %], and insulin [-2.94 Hedges' g, 95 % CI: -6.67 to 0.80, P = 0.12, I2 = 83.1 %] following supplementation with sumac powder. CONCLUSION This meta-analysis showed no significant effects on any glycemic indices following supplementation with sumac powder.

Abstract
The current study aims to explore the anti-inflammatory activity of Chlorella pyrenoidosa on RAW 267.4 cells and followed by a cross-over clinical trial in healthy subjects to check the antioxidant and anti-aging properties of Chlorella water extract (CWE). For the clinical trial, 44 healthy subjects were requested to consume 27 ml of either placebo or CWE for 90 days (phase I) and vice-versa manner for 90 days (phase II) with 4 weeks of washout period. The RAW 264.7 macrophages treated with Chlorella display potent anti-inflammatory activity by significantly downregulating (p < .05) the protein expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Whereas, the subjects supplemented with CWE showed improved (p < .05) antioxidant status (TEAC, SOD, CAT, and DHEAs) and lower (p < .05) oxidative stress/aging markers (TBARS and 8-OHdG) as well as considerably (p < .05) protected liver (by lowering GOT and GPT). Thus, consumption of chlorella could significantly improve the overall health status by suppressing various oxidative stress markers and aging stress markers. PRACTICAL APPLICATIONS: Chlorella is considered as a popular functional food owing to its rich nutrient value and its array of biological activities. Numerous studies indicated that treatment with Chlorella spp. would considerably lower oxidative stress, inflammation, and regulate immune response which might contribute to anti-aging property in various cell and animal models. Based on the above information, we expected that Chlorella would be a better contender for the development of a novel anti-aging agent. Hence, we designed this clinical trial to assess the beneficial effects of Chlorella pyrenoidosa especially anti-aging. In agreement with our hypothesis, our results also showed that subjected supplemented with Chlorella water extract could significantly improve overall health status by suppressing various oxidative stress markers and aging stress markers. Hence, Chlorella could be developed into a novel anti-aging agent. In the future, it can be prescribed with standard anti-aging agents to improve the overall health status of the elderly population. However, large-scale clinical studies are needed to confirm our statements.

Abstract
In recent times many researchers are expressing immense interest in nutraceuticals and functional foods for combating various diseases or abnormal conditions, especially against hypertension (HT). Persistent HT is medically referred to as chronic high blood pressure (BP) and considered to be one of the major risk factors for the deadliest diseases including cardiovascular disease (CVD) and cerebrovascular diseases. Hence HT poses a serious socio-economic burden worldwide, particularly to developing countries. The current treatment strategy for HT includes standard anti-hypertensive drugs, which are associated with many adverse effects and lower drug adherence rates. Therefore, an alternative or complementary natural therapy (functional foods or nutraceuticals or dietary supplements) would be the alternate choice along with a modified lifestyle pattern that might help to manage or combat HT and its related complications. During this review, the author would like to shed light on the basic science behind HT including pathophysiology and the impact of dietary salt on HT and the impact of various functional foods or nutraceuticals against HT in humans (meta-analysis and systemic review). This contribution gives a better idea (public health perspective) for choosing the best functional foods/nutraceuticals for the prevention, management or delaying the onset of HT and its associated conditions along with modified lifestyle patterns and standard anti-hypertensive drugs.

Abstract
Hypertension (HT) is one of the pivotal risk factors for various detrimental diseases like cardiovascular diseases (CVDs), cerebrovascular disease, and renal dysfunction. Currently, many researchers are paying immense attention to various diet formula (dietary approach) with a special focus on micro and macronutrients along with modified lifestyle and standard anti-hypertensive drugs. Micronutrients (minerals/vitamins) play a central role in the regulation of blood pressure (BP) as they aid the function of macronutrients and also improve the anti-hypertensive functions of some anti-hypertensive agents. Even though several studies have demonstrated the beneficial effects of micronutrients on controlling BP, still some ambiguity exists among the nutritionists/doctors, which combination or individual mineral (dietary approach) contributes to better BP regulation. Therefore, this critical review article was attempted to delineate the underlying role of micronutrients (minerals and vitamins) for the management and prevention or delaying of HT and their related complications with strong affirmation from clinical trials as well as its mechanism of controlling BP. Moreover, the major source and recommended daily allowance (RDA) of various micronutrients are included in this review for guiding common readers (especially HT subjects) and dieticians to choose/recommend a better micronutrient and their combinations (other nutrients and standard anti-hypertensive drugs) for lowering the risk of HT and its related co-morbid conditions like CVDs.

Abstract
Several studies have reported that probiotics could modulate host lipid metabolism via altering the intestinal microbiota. Hence, the current study was aimed to assess the efficacy of a mixture of probiotic-contained milk formula (PMF) with three different bacterial strains [Lactobacillus acidophilus (La5), Lactobacillus casei (TMC), Bifidobacterium lactis (Bb12)] on lipid profile and intestinal function in healthy mild hypercholesterolemic volunteers. Totally, 40 healthy mild hypercholesterolemic subjects (180-220 mg/dL) were randomly assigned into two groups as placebo or experimental group. All the subjects were requested to drink either PMF (experimental) or skimmed milk drink formula-placebo (30 g mixed with 200 mL of water) for 10 weeks and continued by 2 weeks of the follow-up period. Supplementation of PMF for 10 weeks significantly improved (p < 0.05) the fecal weight, fecal movement (decreased fecal gastrointestinal passing time) by improving intestinal microbiota (increasing beneficial bacterial species like Lactobacillus, Bifidobacterium spp.), and lag time of low-density lipoprotein (LDL) oxidation. Also, intake of PMF substantially reduced (p < 0.05) the levels of total cholesterol (TC; 8.1%) and low-density lipoprotein cholesterol (LDL-c; 10.4%) and thus showcasing its cardioprotective efficacy. PMF considerably improves gastrointestinal function by modulating fecal movement, intestinal microbiota, and decrease cholesterol and might be helpful in the management of hypercholesterolemia.

Abstract
BACKGROUND Studies on the efficacy of artichoke administration on anthropometric indices gave different outcomes. Hence, a systematic review and dose-response meta-analysis were accomplished to understand the effects of artichoke administration on anthropometric indices. METHODS Related clinical trials were found by searching in PubMed, Embase, the Cochrane Library and Scopus databases up to 29 February 2020. Weighted Mean Differences (WMD) were analyzed using a random-effects model. Heterogeneity, publication bias and sensitivity analysis were assessed for anthropometric indices. RESULTS Pooled analysis of 10 randomized controlled trials (RCTs) suggested that the artichoke administration has effect on waist circumference (WMD: -1.11 cm, 95 % CI: -2.08 to - 0.14), as opposed to the other anthropometric indices including weight (WMD: -0.62 kg, 95 % CI: -1.86 to 0.61) or BMI (WMD: -0.12, 95 % CI: -0.43 to 0.20). However, the analysis of the subgroups according to the health status showed that artichoke supplementation in hypertensive patients significantly reduced weight (WMD: -2.34 kg, 95 % CI: -3.11 to -1.57) but not the other indicators (WMD: -0.06 kg, 95 % CI: 0.78 to 0.67). CONCLUSIONS The artichoke supplementation has effect on the waist circumference, but not on the other anthropometric indices. For establishment of more accurate conclusion more studies with longer administration duration are need to be done.

Abstract
In recent times, many scientists have given great attention to nutraceuticals (complementary medicine) as it widely used for promoting health status. In particular for the prevention and treatment of various neurological diseases or disorders without or less adverse effects. The current mini-review was intended to compile all popular (major) nutraceuticals against various neurodegenerative diseases (NDDs) including Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's disease (HD) with special reference to clinical trials. Preliminary reviews indicated that nutraceuticals like curcumin, resveratrol, Epigallocatechin-3-gallate (EGCG), Coenzyme Q10, ω-3 FA (DHA/EPA/ALA), showed better neuroprotective activity against various NDDs in human setting (clinical trial). Hence this contribution will focus only on those popular nutraceuticals with proposed brief mechanisms (antioxidant, anti-inflammatory, mitochondrial homeostasis, autophagy regulation, promote neurogenesis) and its recommendation. This mini-review would aid common people to choose better nutraceuticals to combat various NDDs along with standard neuroprotective agents and modified lifestyle pattern.

Abstract
This study was designed to check whether complexation of royal jelly (RJ) proteins with green tea extract enriched with EGCG, would enhance the bioavailability on C2BBe1 cells. The total phenolic and EGCG of green tea extract (GTex) as well as the protein level of RJ were measured. The best entrapment efficiency (30.47%) was noted at a 10:4 ratio (RJ:EGCG of GTex) to confirm the maximum EGCG-RJ complexation. Followed by in vitro studies to check the cytotoxicity, morphological changes, EGCG uptake, and TBARS (antioxidant) activity were evaluated on C2BBe1 cells. The EGCG-RJ protein complex showed less toxicity without any morphological changes with better cellular EGCG uptake than GTex or GTex-RJ mixture on CeBBe1 cells. Besides, the EGCG-RJ protein complex display maximum TBARS suppressing activity to showcase better stability. This study infers that complexation of RJ proteins with EGCG (EGCG-RJ protein complex) could significantly improve the bioavailability of EGCG. PRACTICAL APPLICATIONS: EGCG is the major active component of green tea, which is responsible for various biological functions. Previous studies have indicated that complexation of EGCG with proteins (act as a carrier) could considerably improve the bioavailability of EGCG. Hence, the author speculates that complexation or combination of RJ with green tea (EGCG), might improve the bioavailability as well as enhance its biological properties. The outcome of this cell line study showed that the EGCG-RJ protein complex showed better bioavailability than EGCG or GTex, and thus, indicating that this novel complex can be used in the future for better EGCG bioavailability with improved biological function. However, further studies are needed to confirm the types of interaction and the reason for better bioavailability.

Abstract
Propolis is a bee wax rich in various phytocomponents and traditionally used to treat various ailments. Propolis is reported to possess an array of biological properties including anti-inflammatory, antioxidant, anti-cancer, and anti-diabetic as well as cardioprotective, hepatoprotective, renoprotective, and derma protective activities. A plethora of studies confirmed that propolis is effective against various types of cancer including head and neck, lung, liver, brain (glioma), pancreas, kidney, prostate, skin (melanoma), breast, oral, esophagus, gastric, colorectal, and bladder cancers. However, many researchers have demonstrated that propolis displays potent chemoprotective/chemopreventive or anti-cancer activity against only a few types of cancers like oral, gastrointestinal, dermal (melanoma), breast, and prostate cancers. Therefore, this mini-review only summarizes the chemopreventive/chemotherapeutic activities of propolis and its updated underlying mechanisms. Taken together, propolis displays potent chemoprotective or anti-cancer effect due to the presence of various phytocomponents which contribute to pro-apoptotic, cytotoxic, anti-proliferative (cell cycle arrest), anti-metastatic, anti-invasive, anti-angiogenic and anti-genotoxic or anti-mutagenic properties along with antioxidant, immunomodulatory, and anti-inflammatory functions. Hence, propolis could be used as an adjuvant for treating various cancers along with standard chemotherapeutic drugs. However, many large-scale clinical studies are needed to justify such applications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fenugreek is a traditional herbal medicine that has been used for centuries to treat hyperglycemia, muscle spasms, gastritis, constipation, edema, and other metabolic disorders. Recently, lipid-lowering effects of fenugreek have been identified. AIM OF THE STUDY The aim of this systematic review and meta-analysis was to determine and clarify the impact of fenugreek supplementation on anthropometric indices and serum lipid levels. MATERIALS AND METHODS We searched PubMed, Scopus, ISI Web of Science, Cochrane Library, and Google Scholar from inception to June 2019 using relevant keywords. All randomized controlled trials (RCTs) investigating the effects of fenugreek on anthropometric indices and plasma lipids in adults were included. A random-effects model was used for quantitative data synthesis. A sensitivity analysis was conducted using the leave-one-out method. RESULTS A meta-analysis of 12 RCTs (14 arms) with 560 participants suggested a significant decrease in plasma concentrations of total cholesterol (WMD = -9.371 mg/dL; 95% CI: -15.419, -3.323, p = 0.002), triglycerides (WMD = -13.776 mg/dL; 95% CI: -26.636, -0.916, p = 0.036), and low density lipoprotein cholesterol (WMD = -6.590 mg/Dl; 95% CI: -13.042, -0.137, p = 0.045), as well as an increase in plasma high density lipoprotein cholesterol (WMD = 3.501 mg/dL; 95% CI: 1.309, 5.692, p = 0.002), while body weight (WMD = 0.223 kg; 95% CI: -0.509, 0.955, p = 0.551) and body mass index (WMD = 0.091 kg/m2; 95% CI: -0.244, 0.426, p = 0.596) were not altered. CONCLUSION Fenugreek supplementation improved lipid parameters in adults. However, to confirm these results, more studies, particularly among hyperlipidemic patients, are needed.

Abstract
This study was aimed to explore the antioxidant and anti-inflammatory activity of various pine needle products (non-fermented, fermented, and commercial) extracted with different solvents (hexane, ethyl acetate, and water) in lipopolysaccharide (LPS) induced RAW 264.7 cells. The phenolic/flavonoid contents of ethyl acetate extract of fermented pine needle (EAE-FPN) is higher than other pine product extracts (hexane/water). The levels of antioxidant indices (TEAC, DPPH) as well as free radical scavenging activity (H2 O2 ) were significantly improved in EAE-FPN than other pine needle product extracts. The levels of ROS and various inflammatory markers (NO, PGE2, TNF-α, and IL-1β/6) were considerably abolished by EAE-FPN in a dose-dependent manner (50-200 μg/ml). Moreover, the protein expressions of inducible NO synthase (iNOS), cyclooxygenase 2 (COX-2), and nuclear factor Kappa B (NF-κB) p65 subunit were also markedly downregulated by EAE-FPN. Collectively, EAE-FPN with phenolic/flavonoid content showed excellent antioxidant and anti-inflammatory properties via modulating NF-κB signaling pathway. PRACTICAL APPLICATIONS: Pine needle drink (Pinus morrisonicola Hay) has been used as a functional beverage for many years due to its various biological properties in Asia especially in Taiwan, China, and Korea. Many researchers hinted various biological activity of fermented pine needle product but none of them explored the in-depth mechanism underpinning its antioxidant and anti-inflammatory properties in LPS-induced RAW 264.7 cell model. Hence, the current cell line study was designed to assess the underlying mechanism behind the antioxidant and anti-inflammatory activity of Pine needles extract (both non-fermented and fermented) in LPS-induced RAW 264.7 cells (macrophage). The outcome of this study distinctly showed that EAE-FPN displayed potent antioxidant and anti-inflammatory activities by regulating NF-κB signaling pathway. Therefore, pine needle could be developed into functional drink to abolish the progression of inflammatory responses in various disease condition.

Abstract
The prevalence of obesity and its related metabolic syndrome (MetS) has shown an upsurge in recent years due to modified lifestyle patterns. The present study was designed to investigate the impact of a nutritionally balanced conventional meal replacement diet with modified macromolecular composition (rich in soy/pea protein and soluble fibers) and caloric restriction on Taiwanese obese subjects. Obese subjects (BMI > 27; n = 50, male 23, female 27) were recruited and requested to replace two meals per day (breakfast and lunch or dinner) with the balanced nutritional meal replacement diet (equal to 240 kcal) for 8 weeks with one regular meal and make sure that the daily target calorie limit (caloric restriction) was less than 1500 kcal day-1 for men and 1200 kcal day-1 for women. After eight weeks of intervention with a calorie-restricted balanced partial meal replacement diet, the levels of body weight, body fat, and waist circumference were significantly reduced by 4.1 kg, 2.38%, and 5.06 cm, respectively. The levels of serum total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-c) were significantly decreased (p < 0.05) with a significant increase (p < 0.05) in high-density lipoprotein cholesterol (HDL-c) levels after 8 weeks of intervention with the meal replacement diet. Moreover, the levels of insulin, homeostatic model assessment-insulin resistance (HOMA-IR), leptin, thiobarbituric acid reactive substances (TBARS) and cardiovascular risk factors were significantly attenuated (p < 0.05). To conclude, the present intervention with meal replacement and caloric restriction on obese subjects could concomitantly decrease the body weight and glycemic and cardiovascular risk factors and thereby lower the risk of various metabolic disorders.

Abstract
This study aimed to compare the beneficial effect of catechin-enriched green tea and oolong tea on mildly hypercholesterolemic subjects. Sixty mildly hypercholesterolemic subjects (180-220 mg dL-1) were enrolled and divided into three groups as catechin-enriched green tea (CEGT), catechin-enriched oolong tea (CEOT) or placebo. The subjects were instructed to drink 2 × 300 mL of CEGT (780.6 mg of catechin), CEOT (640.4 mg of catechin) or placebo beverage for 12 weeks. Drinking CEGT and CEOT significantly decreased (p < 0.05) the body weight, fat, and BMI, lipid peroxidation as well as lipid profile (TC, LDL-c, HDL-c, and TG). Also, intervention with CEGT and CEOT significantly improved (p < 0.05) the oxidative indices (TEAC and GSH) and antioxidant enzymes (SOD, CAT, GPx, and GR). Moreover, ultrasound examination endorsed the hepatoprotective activity of CEGT and CEOT by reverting mild fatty liver to the normal hepatic condition because of antioxidant and hypolipidemic activities. To summarize, both CEGT and CEOT showed similar antioxidant and hepatoprotective activities. However, CEOT displayed superior lipid-lowering activity compared to CEGT or placebo, and hence it could be used to amend the wellness condition of mildly hypercholesterolemic subjects.

Abstract
Cardiovascular disease (CVD) is the most common non-communicable ailment which claims one-third of total global death. This contribution provides an overview of cardiovascular diseases (CVDs), hypercholesterolemia and hyperlipidemia (dyslipidemia) and their related complications as well as the current treatment options with special attention to popular functional foods and nutraceuticals. Currently, many synthetic lipid-lowering drugs are available in the market. However, they trigger several adverse effects. Thus, to overcome this problem nutraceuticals and functional foods which are considered safe, and with multifaceted lipid-lowering activity are highly recommended (adjuvant therapy) for treating dyslipidemia. This review intends to shed light on how to choose the appropriate or better nutraceutical/functional food ingredients to alleviate the risk of CVD, based on recent literature survey with the inclusion of clinical trials and meta-analysis to ensure the efficacy of nutraceuticals/ functional foods on lipid profile.

Abstract
BACKGROUND Burdock complex (BC) constitutes of burdock (Arctium lappa), angelica (Angelica sinensis), gromwell (Lithospermum erythrorhizon), and sesame (Sesamum indicum) oil, which are commonly used in traditional Chinese medicine (TCM) for treating various disorders. This study intended to examine the anti-H. pylori activity of BC on AGS cell model as well as in asymptomatic H. pylori-infected subjects. MATERIALS AND METHODS AGS cell incubated with H. pylori and treated with BC to evaluate the minimum inhibition concentration (MIC), cell viability (MTT) anti-adhesion activity, and inflammatory markers. In case of clinical trial, H. pylori-positive subjects (urea breath test [UBT] >10%, n = 36) were enrolled and requested to intake BC (n = 19) or placebo (n = 17) for 8 weeks. Antioxidant capacity, total phenol, UBT, inflammatory markers were analyzed at the initial, 4th, 8th, and 10th weeks. Moreover, the endoscopic examination was carried out on baseline and 10th week. RESULTS In vitro studies showed that BC treatment significantly inhibited (P < .05) the inflammatory markers and adhesion of H. pylori to AGS cell. However, H. pylori-infected subject ingested with BC for 8 weeks significantly decreased (P < .05) the UBT value, inflammatory markers with improved antioxidant activity, and phenolic levels as compared to placebo. Also, consumption of BC considerably healed the ulcer wound. CONCLUSION Overall, the BC could attenuate H. pylori infection by inhibiting H. pylori adhesion and subsequent inflammatory response on the gastric epithelial cell (AGS) as well as clinically ameliorated UBT, antioxidant capacity, and alleviated inflammation to display its anti-H. pylori activity.

Abstract
CONTEXT Prunus domestica Linn (Rosaceae) has been considered a functional food, owing to its various pharmacological activities, including antioxidant, anti-inflammatory, antidiabetic and anticancer. OBJECTIVE This placebo-controlled, randomized study was framed to check the beneficial activity of prune essence concentrates (PEC) in corroboration with intestinal function and lipid profile in mildly hypercholesterolemic subjects. MATERIALS AND METHODS Sixty healthy mild hypercholesterolemic subjects were randomly chosen and segregated into three groups as placebo (consume 50 mL of simulated prune drink), PEC I (consume 50 mL of PEC/day) and PEC II (consume 100 mL of PEC/day) for 4 weeks with 2 weeks of follow-up without PEC consumption. RESULTS Intake of PEC (I and II) for 4 weeks substantially ameliorated (p < 0.05) the colony number of Bifidobacterium spp. (1.18- and 1.19-fold) and Lactobacillus spp. (1.07- and 1.16-fold), but markedly lowered (p < 0.05) the colony number of Clostridium perfringens (5.97 and 8.35%) and Escherichia coli (6.25 and 9.38%). Meanwhile, the total cholesterol (TC; 5.90 and 6.99%) levels and LDL-c (6.68 and 6.53%) were significantly reduced (p < 0.05), but no change in other lipid parameters. Whereas, the antioxidant capacity was also concomitantly elevated (p < 0.05) upon administration with PEC. DISCUSSION AND CONCLUSION Overall, the results suggest that the use of PEC may positively regulate the intestinal microflora and thereby effectively lower the TC levels and thus act as a hypocholesterolemic agent.

Abstract
CONTEXT Royal jelly (RJ) has been reported for its health promoting factors such as antioxidant, anti-inflammatory and lipid lowering activities. OBJECTIVE The present randomized, placebo-controlled study examines the hypolipidemic beneficial effect of RJ through evaluating anthropometric measurements, lipid profile and various hormone levels in mildly hypercholesterolemic participants. MATERIALS AND METHODS Forty subjects with mild hypercholesterolemia (180-200 mg/dL) were randomly selected and divided into two groups as experimental or placebo, who requested to intake nine capsules (350 mg/capsule) of RJ or placebo/day, respectively, for three months with one month of follow-up without any supplementation. RESULTS No significant changes were noted in any of the anthropometric parameters like body weight, waist and body fat. The serum total cholesterol (TC; 207.05-183.15 mg/dL) and low-density lipoprotein cholesterol (LDL-c; 126.44-120.31 mg/dL) levels were reduced significantly (p < 0.05) after administration of RJ. However, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-c) levels were not considerably altered. Moreover, three months of RJ consumption significantly ameliorated (p < 0.05) the concentration of sex hormones like dehydroepiandrosterone sulphate (DHEA-S; 1788.09-1992.31 ng/mL). Also, intake of RJ did not elicit any hepatic or renal damage. DISCUSSION AND CONCLUSION Intervention with RJ for three months considerably lowered the TC and LDL-c levels through improving the levels of DHEA-S and thus alleviates the risk of cardiovascular disease (CVD).

Abstract
CONTEXT Ganoderma lucidum (Leyss: Fr) Karst. (Polyporaceae) is an oriental medicinal fungus, commonly used in traditional Chinese medicine (TCM) for treating various condition or diseases such as hypertension, hyperglycaemia, hepatitis and cancer. OBJECTIVE The current study examines whether triterpenoids and polysaccharide-enriched G. lucidum (GL) influence antioxidation and hepatoprotective efficacy by suppressing oxidative stress. MATERIALS AND METHODS Forty-two healthy subjects (22 male and 20 female) were recruited and segregated into two groups as experimental or placebo and requested to intake GL (n = 21) or placebo (n = 21) capsule (225 mg; after lunch or dinner) for six consecutive months and vice versa with one month washout period in between. The anthropometric analysis and biochemical assays, as well as abdominal ultrasonic examination were performed. RESULTS Consumption of GL substantially improved (p < 0.05) the total antioxidant capacity (TEAC; 79.33-84.04), total thiols and glutathione content (6-8.05) in plasma as well as significant (p < 0.05) enhanced the activities of antioxidant enzymes. Whereas, the levels of thiobarbituric acid reactive substances (TBARS; 3.37-2.47), 8-hydroxy-deoxy-guanosine (8-OH-dG; 15.99-11.98) and hepatic marker enzymes (glutamic-oxaloacetic transaminase; GOT and glutamic-pyruvic transaminase; GPT) were concomitantly reduced (42 and 27%) on treatment with GL. Furthermore, the abdominal ultrasonic examination in GL subjects displayed a notable alteration on hepatic condition by reversing from mild fatty liver condition (initial) to normal condition. DISCUSSION AND CONCLUSION The outcome of the present intervention demonstrated the antioxidation, anti-aging and hepatoprotective nature of GL by effectively curbing oxidative stress.

Abstract
CONTEXT Cranberry has numerous biological activities, including antioxidation, anticancer, cardioprotection, as well as treatment of urinary tract infection (UTI), attributed to abundant phenolic contents. OBJECTIVE The current study focused on the effect of cranberry juice (CJ) on blue light exposed human retinal pigment epithelial (ARPE-19) cells which mimic age-related macular degeneration (AMD). MATERIALS AND METHODS Preliminary phytochemical and HPLC analysis, as well as total antioxidant capacity and scavenging activity of cranberry ethyl acetate extract and different CJ fractions (condensed tannins containing fraction), were evaluated. In cell line model, ARPE-19 were irradiated with blue light at 450 nm wavelength for 10 h (mimic AMD) and treated with different fractions of CJ extract at different doses (5-50 μg/mL) by assessing the cell viability or proliferation rate using MTT assay (repairing efficacy). RESULTS Phytochemical and HPLC analysis reveals the presence of several phenolic compounds (flavonoids, proanthocyanidin, quercetin) in ethyl acetate extract and different fractions of CJ. However, the condensed tannin containing fraction of ethyl acetate extract of CJ displayed the greater (p < 0.05) scavenging activity especially at the dose of 1 mg/mL. Similarly, the condensed tannin containing fraction at 50 μg/mL presented better (p < 0.05) repairing ability (increased cell viability). Furthermore, the oligomeric condensed tannin containing fraction display the best (p < 0.05) repairing efficiency at 50 μg/mL. DISCUSSION AND CONCLUSION In conclusion, this study distinctly proved that condensed tannin containing fraction of CJ probably exhibits better free radicals scavenging activity and thereby effectively protected the ARPE-19 cells and thus, hampers the progress of AMD.

Abstract
Pearl is one of the well-known traditional Chinese medicine (TCM) prescribed for treating various skin and bone related disorders due to its abundant proteins and mineral contents. The present investigation focused on antioxidation and life span prolonging effects from different extracts of pearl powder. During in vitro studies, various oxidative indices were evaluated, along with lifespan-prolonging effect were checked using wild-type Caenorhabditis elegans. For the clinical trial, 20 healthy middle-aged subjects were recruited and separated into 2 groups as experimental and placebo group, who received 3 g of pearl powder/d (n = 10) and 3 g of placebo/d (n = 10) for 8 weeks, respectively. During the initial, 2nd, 4th, 6th, 8th and 10th weeks the blood samples were collected for biochemical analysis. The protein extract of pearl powder recorded maximum (p < 0.05) antioxidant activity (20–68%) as well as efficiently prolonged the life span of C. elegans by 18.87%. Pearl powder supplemented subjects showed a substantial increase (p < 0.05) in total antioxidant capacity from 0.45 to 0.69 mM, total thiols from 0.23 to 0.29 mM, Glutathione content from 5.89 to 9.19 μM, enzymic antioxidant activity (SOD-1248 to 1308; Gpx-30 to 32; GR-2.4 to 2.9) as well as considerably suppressed the lipid peroxidation products from 4.95 to 3.27 μM. The outcome of both in-vitro and in-vivo antioxidant activity inferred that protein extract of pearl powder was a potent antioxidant and thereby prolonged the lifespan of C. elegans. Hence, pearl powder could be recommended for treating various age-related degenerative disorders.

Abstract
In recent years, the use of fermented plant products to protect against various metabolic syndromes has been increasing enormously. The objective of this study was to check the regulatory efficacy of fermented plant extract (FPE) on intestinal microflora, lipid profile, and antioxidant status in mildly hypercholesterolemic volunteers. Forty-four mildly hypercholesterolemic individuals (cholesterol 180–220 mg/dL) were recruited and assigned to two groups: experimental or placebo. Volunteers were requested to drink either 60 mL of FPE or placebo for 8 weeks. Anthropometric measurements were done in the initial, 4th, 8th, and 10th weeks. The anthropometric parameters such as body weight, body fat, and body mass index were markedly lowered (p < 0.05) on FPE intervention participants. Moreover, the total antioxidant capacity and total phenolics in plasma were considerably increased along with a reduction (p < 0.05) in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-c) after FPE supplementation. Participants who drank FPE showed a pronounced increase (p < 0.05) in the number of beneficial bacteria such as Bifidobacterium spp. and Lactobacillus spp., whereas the number of harmful bacteria such as Escherichia coli and Clostridium perfringens (p < 0.05) were concomitantly reduced. Furthermore, the lag time of LDL oxidation was substantially ameliorated in FPE-administered group, thus indicating its antioxidative and cardioprotective properties. Treatment with FPE substantially improved the intestinal microflora and thereby positively regulated various physiological functions by lowering the anthropometric parameters, TC, and LDL-c, and remarkably elevated the antioxidant capacity and lag time of LDL oxidation. Therefore, we recommended FPE beverage for combating hypercholesterolemia.

Abstract
Clinical pharmacodynamic evaluation is a key component of the "pharmacologic audit trail" in oncology drug development. We posit that its value can and should be greatly enhanced via application of a robust quantitative pharmacology framework informed by biologically mechanistic considerations. Herein, we illustrate examples of intersectional blindspots across the disciplines of quantitative pharmacology and translational science and offer a roadmap aimed at enhancing the caliber of clinical pharmacodynamic research in the development of oncology therapeutics.

Abstract
Background Si-Wu-Tang (SWT) is used to treat various gynecological disorders in Chinese medicine. This study investigated the antioxidant and physiological effects of SWT on the skin and liver in healthy adults. Methods This randomized, crossover, double-blind, placebo-controlled clinical trial was conducted at Chung Shan Medical University Hospital in December 2008. Participants with uncontrolled diabetes, heart disease, liver disease, kidney disease, cancer, and pregnancy were excluded. Sixty healthy volunteers taking no medications were recruited from the community based on the results of their medical history questionnaires and biochemical analyses to confirm their health status. The participants were assigned to two groups: one group drank 125 mL of placebo (n = 30) and the other drank SWT (n = 30) for six continuous days per month for 6 months. The placebo and SWT were then switched between the groups after a 1-month washout period. Anthropometric measurements (body weight, body fat, and body mass index) were performed and fasting blood samples were drawn for various biochemical assays at 1, 3, 6, 10 and 13 months. Abdominal ultrasound and skin examinations were performed at 1, 6 and 13 months. The skin examinations involved assessment of skin roughness, sebum content, hydration, surface water loss, erythema, melanin index, and elasticity on the face (sunlight-exposed sites: middle of ear and nose) and inner arm (sunlight-unexposed sites: center of wrist and elbow joint). Results Administration of SWT significantly increased the antioxidant index (P = 0.001) and antioxidant enzymes activities (P = 0.001) from baseline to month 6. SWT also suppressed the concentration of serum lipids (triglycerides, P = 0.01; high-density lipoprotein cholesterol, P = 0.23; low-density lipoprotein cholesterol, P = 0.48) and hepatic marker enzymes (glutamic pyruvic transaminase, P = 0.76; glutamic oxaloacetic transaminase, P = 0.65) when compared with the placebo group. Abdominal ultrasound in the SWT group revealed a positive impact of SWT on mild fatty liver, gallstones, and mild splenomegaly. Moreover, SWT intake concomitantly elevated erythema (P = 0.011) and markedly lowered skin surface water loss (P = 0.016), sebum content (P = 0.021), and wrinkles (P = 0.024). Conclusions Oral administration of SWT for 6 months improved the antioxidant level and positively regulated the lipid profile, liver function, and skin integrity and texture.

Abstract
The objective of this study was to evaluate the efficacy of the red wine extract of onion (RO) and red wine (RW) on alleviating the risk factors of cardiovascular disease. During in vitro studies, various antioxidant activities [trolox equivalent antioxidant capacity (TEAC), DPPH, and H2 O2 scavenging ability] of RO and RW group were evaluated. Both RO and RW showed the maximum antioxidant capacity. During in vivo studies, 23 healthy hypercholesterolemic volunteers were randomly selected and assigned into two groups, who drunk 250 mL of RO (n = 11) or RW (n = 10) for 10 weeks. No significant changes were observed in anthropometric parameters (body weight, height, body mass, and BMI) in each group. Both RW and RO extracts elevated (p < 0.05) antioxidant activity and thereby prolonging the lag time of low-density lipoprotein oxidation. However, RO extract intake substantially suppressed (p < 0.05) the total cholesterol and low-density lipoprotein cholesterol levels when equivalence with RW thus, indicating its additional hypocholesterolemic effect. The inflammatory markers such as factor VII were also positively modulated by RO extract. Results indicated that RO extract consumption rendered better cardio protective effect than RW by altering cholesterol, improving antioxidation and suppressing inflammatory marker levels and thereby, attenuating the cardiovascular disease incidence.

Abstract
We introduce a hybrid nanostructured biomaterial that is a combination of rare phases of immiscible gold and silicon oxide, functionalized via ultrafast laser synthesis. For the first time, we show cancer controlling properties of rare phases of gold silicides, which include Au7Si, Au5Si, Au0.7Si2.3 and Au8Si2. Conventionally, pure forms of gold and silicon/silicon oxide are extensively employed in targeted therapy and drug delivery systems due to their unique properties. While silicon and silicon oxide nanoparticles have shown biocompatibility, gold nanoparticles show conflicting results based on their size and material properties. Several studies have shown that gold and silicon combinations produce cell controlling properties, however, these studies were not able to produce a homogenous combination of gold and silicon, owing to its immiscibility. A homogenous combination of gold and silicon may potentially enable properties that have not previously been reported. We describe rare phased gold-silicon oxide nanostructured hybrid biomaterials and its unique cancer controlling properties, owing to material properties, concentration, size and density. The gold-silicon oxide nanostructured hybrid is composed of individual gold-silicon oxide nanoparticles in various concentrations of gold and silicon, some nanoparticles possess a gold-core and silicon-shell like structure. The individual nanoparticles are bonded together forming a three dimensional nanostructured hybrid. The interaction of the nanostructured hybrids with cervical cancer cells showed a 96% reduction in 24h. This engineered nanostructured hybrid biomaterial presents significant potential due to the combination of immiscible gold and silicon oxide in varying phases and can potentially satiate the current vacuum in cancer therapy.

Abstract
Onion (Allium cepa L.) is widely employed as a food ingredient as well as traditional remedy to treat fever, burns, and scurvy. The present study focused on the modulator efficacy of the quercetin rich onion juice on lipid profile and antioxidant status in mildly hypercholesterolemic subjects. Twenty-four healthy subjects with mild hypercholesterolemia (≧ 200 mg/dL) were recruited and divided into two groups, and they consumed 100 mL of onion juice or placebo every day for 8 weeks. Fasting blood samples were collected at initial, 2nd, 6th, 8th, 10th week for estimating various biochemical assays, as well as anthropometric indices. After 8 weeks of intervention, onion juice greatly decreased (p < 0.05) waist circumference, total cholesterol and LDL-c. In addition, it elevates (p < 0.05) total antioxidation capacity and prolong lag-time of LDL oxidation were also noted. To conclude, drinking onion juice could markedly suppress cholesterol level and elevate total antioxidation capacity. Hence, onion juice was probably recommended for combating various cardiovascular diseases.

Abstract
The state-of-the-art in synthesis of nanostructured cell and contra-cell surfaces relies on techniques that utilize elaborate precursor chemicals, catalysts, or vacuum conditions, and any combination thereof. Two type s of nanostructures, sodium oxide (Na2O) nanotips and silicon oxide (SiO2) nanofibers, have been fabricated on soda-lime glass using ultrafast laser ablation. Control over nanotip width was demonstrated via laser dwell time and a new tip formation mechanism is proposed. The nanofibers generated in this work display a level of nanomorphology unseen in other fiber fabrication methods. The resulting fibers show striking morphological similarity to proteins that comprise the natural extra cellular matrix. The interaction of both nanostructures with NIH 3T3 fibroblasts was explored by incubating nanostructured glass with fibroblasts over periods of 12 hours, 1 day, or 1 week. The Na2O nanotip surfaces dissolved within a day yet appeared to induce apoptosis in cells while the SiO2 nanofibers degraded over time but influenced cells to display unique, healthy characteristics such as preferential adhesion to nanofibers and increased microvilli generation. These growth-positive and growth-negative surfaces for cells could find use in novel biological testing equipment.

Abstract
Currently, the use of nano silicon in cancer therapy is limited as drug delivery vehicles and markers in imaging, not as manipulative/controlling agents. This is due to limited properties that native states of nano silicon and silicon oxides offers. We introduce nano-functionalized multi-phased silicon/silicon oxide biomaterials synthesized via ultrashort pulsed laser synthesis, with tunable properties that possess inherent cancer controlling properties that can passivate the progression of cancer. This nanostructured biomaterial is composed of individual functionalized nanoparticles made of a homogenous hybrid of multiple phases of silicon and silicon oxide in increasing concentration outwards from the core. The chemical properties of the proposed nanostructure such as number of phases, composition of phases and crystal orientation of each functionalized nanoparticle in the three dimensional nanostructure is defined based on precisely tuned ultrashort pulsed laser-material interaction mechanisms. The amorphous rich phased biomaterial shows a 30 fold (95%) reduction in number of cancer cells compared to bulk silicon in 48 hours. Further, the size of the cancer cells reduces by 76% from 24 to 48 hours. This method exposes untapped properties of combination of multiple phases of silicon oxides and its applications in cancer therapy.

Abstract
Physiologically based pharmacokinetic (PBPK) modeling and classical population pharmacokinetic (PK) model‐based simulations are increasingly used to answer various drug development questions. In this study, we propose a methodology to optimize the development of drugs, primarily cleared by the kidney, using model‐based approaches to determine the need for a dedicated renal impairment (RI) study. First, the impact of RI on drug exposure is simulated via PBPK modeling and then confirmed using classical population PK modeling of phase 2/3 data. This methodology was successfully evaluated and applied to an investigational agent, orteronel (nonsteroidal, reversible, selective 17,20‐lyase inhibitor). A phase 1 RI study confirmed the accuracy of model‐based predictions. Hence, for drugs eliminated primarily via renal clearance, this modeling approach can enable inclusion of patients with RI in phase 3 trials at appropriate doses, which may be an alternative to a dedicated RI study, or suggest that only a reduced‐size study in severe RI may be sufficient.

Abstract
Despite advances in biomedical research that have deepened our understanding of cancer hallmarks, resulting in the discovery and development of targeted therapies, the success rates of oncology drug development remain low. Opportunities remain for objective dose selection informed by exposure-response understanding to optimize the benefit-risk balance of novel therapies for cancer patients. This review article discusses the principles and applications of modeling and simulation approaches across the lifecycle of development of oncology therapeutics. Illustrative examples are used to convey the value gained from integration of quantitative clinical pharmacology strategies from the preclinical-translational phase through confirmatory clinical evaluation of efficacy and safety.
