Contrasting fertilization response of soil phosphorus forms and functional bacteria in two newly reclaimed vegetable soils.

Fertilization is a pervasive approach to agricultural production enhancing vegetable nutrients such as phosphorus (P) absorption. However, unreasonable fertilization strategies result in high levels of residual P in vegetable planting systems. To better understand the mechanisms of soil phosphorus dynamics responding to inorganic/organic fertilization, we conducted a 3-year field experiment in two newly reclaimed vegetable fields in southern China. The results revealed that soil Olsen-P in CF (mineral fertilization) and OF (Combined application of organic and inorganic fertilizers) increased by approximately 210.6 % and 183.6 %, respectively, while stable P proportion decreased by approximately 9.2 % and 18.1 %, respectively, compared with CK. Combined application of organic and inorganic fertilizer increased the proportion of moderately labile P (NaOH-P) by 1-6 % in comparison with chemical fertilizer and facilitated the conversion from diester-P to monoester-P, indicating that applying pig manure enhanced the potential soil P bioavailability. Besides, organic-inorganic fertilization shaped a bacterial community with more connectivity and stability and changed keystone taxa related to the P transformation of the network. Phenylobacterium, Solirubrobacter, and Modestobacter were regarded as core genera for mobilizing soil phosphorus. However, residual P content in newly reclaimed soils under fertilization, especially for chemical fertilizer, remained non-negligible and may cause potential environmental risks. The partial least squares path modeling results demonstrated that fertilization management had both direct and indirect positive effects on P fraction through the improvement of soil nutrients e.g. total N and soil organic carbon, and bacterial community, while soil properties mainly determined the variation of soil P species. Our results provide comprehensive insights into the current status of legacy P forms and the vital role of fertilizer, key soil properties and bacteria in P dynamics in newly reclaimed vegetable field.

Association of dietary intake with micronutrient deficiency in Indian school children: a cross-sectional study.

Adequate nutrition is necessary during childhood and early adolescence for adequate growth and development. Hence, the objective of the study was to assess the association between dietary intake and blood levels of minerals (calcium, iron, zinc, and selenium) and vitamins (folate, vitamin B12, vitamin A, and vitamin D) in urban school going children aged 6-16 years in India, in a multicentric cross-sectional study. Participants were enrolled from randomly selected schools in ten cities. Three-day food intake data was collected using a 24-h dietary recall method. The intake was dichotomised into adequate and inadequate. Blood samples were collected to assess levels of micronutrients. From April 2019 to February 2020, 2428 participants (50⋅2 % females) were recruited from 60 schools. Inadequate intake for calcium was in 93⋅4 % (246⋅5 ± 149⋅4 mg), iron 86⋅5 % (7⋅6 ± 3⋅0 mg), zinc 84⋅0 % (3⋅9 ± 2⋅4 mg), selenium 30⋅2 % (11⋅3 ± 9⋅7 mcg), folate 73⋅8 % (93⋅6 ± 55⋅4 mcg), vitamin B12 94⋅4 % (0⋅2 ± 0⋅4 mcg), vitamin A 96⋅0 % (101⋅7 ± 94⋅1 mcg), and vitamin D 100⋅0 % (0⋅4 ± 0⋅6 mcg). Controlling for sex and socioeconomic status, the odds of biochemical deficiency with inadequate intake for iron [AOR = 1⋅37 (95 % CI 1⋅07-1⋅76)], zinc [AOR = 5⋅14 (95 % CI 2⋅24-11⋅78)], selenium [AOR = 3⋅63 (95 % CI 2⋅70-4⋅89)], folate [AOR = 1⋅59 (95 % CI 1⋅25-2⋅03)], and vitamin B12 [AOR = 1⋅62 (95 %CI 1⋅07-2⋅45)]. Since there is a significant association between the inadequate intake and biochemical deficiencies of iron, zinc, selenium, folate, and vitamin B12, regular surveillance for adequacy of micronutrient intake must be undertaken to identify children at risk of deficiency, for timely intervention.

Garlic supplementation improves intestinal transit time, lipid accumulation product and cardiometabolic indices in subjects with metabolic syndrome: A randomized controlled trial.

Subjects with metabolic syndrome (MetS) are at increased risk for cardiovascular disease (CVD). Altered gut microbiota is involved in the pathogenesis of MetS. It has been hypothesized that garlic can improve intestinal transit time and cardiovascular risks. We investigated the effect of garlic powder supplementation on intestinal transit time, lipid accumulation product (LAP), and cardiometabolic indices in subjects with MetS. A double-blind randomized controlled trial was conducted for 3 months among subjects with MetS. Ninety subjects were randomly assigned to the treatment group (intake of 1,600 mg/d garlic powder) or control group (placebo) using a computer-generated random number table. All participants were asked to follow the common healthy dietary recommendations during follow-up. The primary outcomes included intestinal transit time, LAP, cardiometabolic index (CMI), atherogenic index of plasma (AIP), Castelli risk index I (CRI-I) and Castelli risk index II (CRI-II). Garlic powder compared to the placebo improved intestinal transit time (p = .001), LAP (-21.5 ± 23.4 vs. 0.7 ± 21.5; p < .001), CMI (-0.85 ± 0.8 vs. 0.13 ± 0.8; p < .001), AIP (-0.14 ± 0.1 vs. 0.01 ± 0.1; p < .001), CRI-I (-0.69 ± 0.5 vs. 0.16 ± 0.5; p < .001) and CRI-II (-0.50 ± 0.3 vs. 0.02 ± 0.3; p < .001). Garlic supplementation can improve intestinal transit time, LAP, and cardiometabolic indices.

Design, synthesis, spectroscopic characterizations, single crystal X-ray analysis, in vitro xanthine oxidase and acetylcholinesterase inhibitory evaluation as well as in silico evaluation of selenium-based N-heterocyclic carbene compounds.

Herein, eight new NHC-based selenourea derivatives were synthesized and characterized by using spectroscopic method (1H, 19F, and 13C NMR, FT-IR), and elemental analysis techniques. These compounds were synthesized by mixing benzimidazolium salts, potassium carbonate, and selenium powder in ethyl alcohol. Additionally, the molecular and crystal structures of the three compounds (1c, 2b, and 2c) were determined using the single-crystal x-ray diffraction (XRD) method. Diffraction analysis demonstrated the partial carbon-selenium double-bond character of these compounds. All compounds were determined to be highly potent inhibitors for AChE and XO enzymes. The IC50 values for the compounds were found in the range of 0.361-0.754 µM for XO and from 0.995 to 1.746 µM for AChE. The DNA binding properties of the compounds were investigated. These compounds did not have a remarkable DNA binding property. Also, DPPH radical scavenging activities of the compounds were also investigated. Compounds (1c), (2a), (3a), and (3b) exhibited more pronounced DPPH radical scavenging activity when compared to other compounds. Docking studies were applied by using AutoDock 4 to determine interaction mechanism of the selected compounds (1a), (1b), and (3b). The compound (1b) has good binding affinity (-9.78 kcal/mol) against AChE, and (-6.86 kcal/mol) for XO target. Drug similarity properties of these compounds compared to positive controls were estimated and evaluated by ADMET analysis. Furthermore, molecular dynamics simulations have been applied to understand the accuracy of docking studies. These findings and the defined compounds could be potential candidates for the discovery and progress of effective medicine(s) for AChE and XO in the future.Communicated by Ramaswamy H. Sarma.

Antimicrobial activity of the biologically synthesized zinc oxide nanoparticles against important rice pathogens.

Global rice production is seriously affected by many abiotic and biotic factors. Among the aggressive rice pathogens, Xanthomonas oryzae pv. oryzae (X. o. pv. oryzae), Bipolaris oryzae (B. oryzae) and Sphaerulina oryzina (S. oryzina) cause bacterial leaf blight, brown leaf spot and narrow brown leaf spot diseases, respectively. The objective of this study was to evaluate the efficacy of biogenic zinc oxide nanoparticles (ZnO NPs) as antimicrobial agent to control rice pathogens. This is the first report of antifungal activity evaluation of ZnO NPs against B. oryzae and S. oryzina. A pre-characterized bacterial strain Escherichia sp. SINT7 was bio-prospected for synthesis of green ZnO NPs. The NPs were confirmed by a characteristic peak measured at 360.96 nm through UV-Vis spectroscopy. Further, the NPs were characterized to elucidate the surface capping molecules, crystallite structure and morphology by various spectroscopic and imaging techniques, which confirmed the spherical shape of NPs with size ranging from 13.07 to 22.25 nm. In vitro studies against X. o. pv. oryzae pathogen depicted the substantial antibacterial activity (up to 25.7 mm inhibition zone at 20 µg/ml NPs concentration). Similarly, ZnO NPs reduced the mycelial growth of B. oryzae and S. oryzina up to 72.68 and 95.78%, respectively at 50 µg/ml concentration on potato dextrose agar plates, while the mycelial biomass reduction was found to be 64.66 and 68. 49% for B. oryzae and S. oryzina, respectively on potato dextrose broth media as compared to control without the addition of NPs. The green ZnO NPs also significantly reduced the fungal spore germination and a disintegration of fungal hyphae for both fungal strains was observed under the microscope as a result of NPs treatment. Hence, it was concluded that biologically synthesized ZnO NPs are potential antimicrobials and could be compared in greenhouse pathogenicity assays with commercial pesticides to control rice pathogens.

Effects of curcumin and/or coenzyme Q10 supplementation on metabolic control in subjects with metabolic syndrome: a randomized clinical trial.

BACKGROUND: Metabolic syndrome (MetS) as a cluster of conditions including hyperlipidemia, hypertension, hyperglycemia, insulin resistance, and abdominal obesity is linked to cardiovascular diseases and type 2 diabetes. Evidence suggested that intake of curcumin and coenzyme Q10 may have therapeutic effects in the management of MetS. AIMS: We investigated the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components including systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference (WC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-c) and fasting plasma glucose (FPG) as primary outcomes, and total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) and body mass index (BMI) as secondary outcomes in subjects with MetS. METHODS: In this 2 × 2 factorial, randomized, double-blinded, placebo-controlled study, 88 subjects with MetS were randomly assigned into four groups including curcumin plus placebo (CP), or coenzyme Q10 plus placebo (QP), or curcumin plus coenzyme Q10 (CQ), or double placebo (DP) for 12 weeks. RESULTS: The CP group compared with the three other groups showed a significant reduction in HDL-c (P = 0.001), TG (P <  0.001), TC (P <  0.001), and LDL-c (P <  0.001). No significant differences were seen between the four groups in terms of SBP, DBP, FPG, WC, BMI and weight. CONCLUSION: Curcumin improved dyslipidemia, but had no effect on body composition, hypertension and glycemic control. Furthermore, coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 showed no therapeutic effects in subjects with MetS.

Effect of L-carnitine supplementation on lipid accumulation product and cardiovascular indices in women with overweight/obesity who have knee osteoarthritis: a randomized controlled trial.

BACKGROUND: Osteoarthritis is associated with obesity, dyslipidemia and cardiovascular diseases. It has been hypothesized that L-carnitine can improve cardiovascular risk factors. We aimed to investigate the effect of L-carnitine supplementation on lipid accumulation product (LAP) and atherogenic indices in women with overweight/obesity who have knee osteoarthritis. METHODS: In this double-blind randomized controlled trial, seventy-six women with overweight/obesity who had knee osteoarthritis were assigned into the intervention group and control group for 12 weeks. The intervention group received 1000 mg/day L-carnitine as capsule, and the control group received placebo. The primary outcomes were LAP, atherogenic index of plasma (AIP), atherogenic coefficient (AC) and Castelli risk index II (CRI-II). RESULTS: We found no significant difference between the groups in baseline values of LAP, AIP, AC and CRI-II. After the intervention, a significant reduction in LAP was observed in intervention group compared to the control group (- 11.05 (- 28.24 to 0.40) vs. - 5.82 (- 24.44 to 2.68); P = 0.03). However, there was no significant difference between two groups in AIP (- 0.05 ± 0.16 vs. - 0.01 ± 0.13; P = 0.19), AC (- 0.40 ± 0.81 vs. - 0.30 ± 0.67; P = 0.67) and CRI-II (- 0.20 ± 0.76 vs. - 0.21 ± 0.47; P = 0.11). CONCLUSIONS: L-carnitine supplementation for 12 weeks can improve LAP, but it has no effect on cardiovascular outcomes. To reach a definitive conclusion, further clinical trials with larger sample sizes and higher dosages of L-carnitine are needed.

Structural interactions of phytoconstituent(s) from cinnamon, bay leaf, oregano, and parsley with SARS-CoV-2 nucleocapsid protein: A comparative assessment for development of potential antiviral nutraceuticals.

SARS-CoV-2 has been responsible for causing 6,218,308 deaths globally till date and has garnered worldwide attention. The lack of effective preventive and therapeutic drugs against SARS-CoV-2 has further worsened the scenario and has bolstered research in the area. The N-terminal and C-terminal RNA binding domains (NTD and CTD) of SARS-CoV-2 nucleocapsid protein represent attractive therapeutic drug targets. Naturally occurring compounds are an excellent source of novel drug candidates due to their structural diversity and safety. Ten major bioactive compounds were identified in ethanolic extract (s) of Cinnamomum zeylanicum, Cinnamomum tamala, Origanum vulgare, and Petroselinum crispum using HPLC and their cytotoxic potential was determined against cancer and normal cell lines by MTT assay to ascertain their biological activity in vitro. To evaluate their antiviral potential, the binding efficacy to NTD and CTD of SARS-CoV-2 nucleocapsid protein was determined using in silico biology tools. In silico assessment of the phytocomponents revealed that most of the phytoconstituents displayed a druglike character with no predicted toxicity. Binding affinities were in the order apigenin > catechin > apiin toward SARS-CoV-2 nucleocapsid NTD. Toward nucleocapsid CTD, the affinity decreased as apigenin > cinnamic acid > catechin. Remdesivir displayed lesser affinity with NTD and CTD of SARS-CoV-2 nucleocapsid proteins than any of the studied phytoconstituents. Molecular dynamics (MD) simulation results revealed that throughout the 100 ns simulation, SARS-CoV-2 nucleocapsid protein NTD-apigenin complex displayed greater stability than SARS-CoV-2 nucleocapsid protein NTD-cinnamic acid complex. Hence, apigenin, catechin, apiin and cinnamic acid might prove as effective prophylactic and therapeutic candidates against SARS-CoV-2, if examined further in vitro and in vivo. PRACTICAL APPLICATIONS: Ten major bioactive compounds were identified in the extract(s) of four medicinally important plants viz. Cinnamomum zeylanicum, Cinnamomum tamala, Origanum vulgare and Petroselinum crispum using HPLC and their biological activity was also evaluated against cancer and normal cell lines. Interestingly, while all extract(s) wielded significant cytotoxicity against cancer cells, no significant toxicity was found against normal cells. The outcome of the results prompted evaluation of the antiviral potential of the ten bioactive compounds using in silico biology tools. The present study emphasizes on the application of computational approaches to understand the binding interaction and efficacy of the ten bioactive compounds from the above plants with SARS-CoV-2 nucleocapsid protein N-terminal and C-terminal RNA binding domains in preventing and/or treating COVID-19 using in silico tools. Druglikeness and toxicity profiles of the compounds were carried out to check the therapeutic application of the components. Additionally, molecular dynamics (MD) simulation was performed to check the stability of ligand-protein complexes. The results provided useful insights into the structural binding interaction(s) that can be exploited for the further development of potential antiviral agents targeting SARS-CoV-2 especially since no specific therapy is still available to combat the rapidly evolving virus and the existing treatment is more or less symptomatic which makes search for novel antiviral agents all the more necessary and crucial.

Prevalence of specific micronutrient deficiencies in urban school going children and adolescence of India: A multicenter cross-sectional study.

INTRODUCTION: Childhood and adolescence require adequate amount of micronutrients for normal growth and development. The primary objective of study was to assess the prevalence of deficiencies of Vitamins (Vitamin A, 25 Hydroxy Vitamin D, Vitamin B12 and Folate) and minerals (Calcium, Zinc, Selenium and Iron), among urban school going children aged 6-11 and 12-16 years in ten cities of India. Secondary objective was to find the association between micronutrient deficiencies with sociodemographic and anthropometric indicators. METHODS: A multi-center cross-sectional study was conducted across India. Participants in the age groups of 6 to 11 years (group 1) and 12 to 16 years (group 2) were selected from randomly chosen schools from each center. Data on socio economic status, anthropometric measures was collected. Blood samples were collected for biochemical analysis of micronutrients. Point estimates and 95% confidence intervals was used to assess the prevalence of deficiencies. Associations were observed using chi square, student t test and ANOVA test. RESULTS: From April 2019 to February 2020, 2428 participants (1235 in group 1 and 1193 group 2) were recruited from 60 schools across ten cites. The prevalence of calcium and iron deficiency was 59.9% and 49.4% respectively. 25 Hydroxy Vitamin D deficiency was seen in 39.7% and vitamin B12 in 33.4% of subjects. Folate, Selenium and Zinc were deficient in 22.2%, 10.4% and 6.8% of subjects respectively. Vitamin A deficiency least (1.6%). Anemia was prevalent in 17.6% subjects and was more common among females. CONCLUSION: One or more micronutrient deficiencies are found in almost one half of school going children in urban area. Hence efforts must be made to combat these on priority. TRIAL REGISTRATION NUMBER: CTRI/2019/02/017783.

Chemical Characterization, In-silico Evaluation, and Molecular Docking Analysis of Antiproliferative Compounds Isolated from the Bark of Anthocephalus cadamba Miq.

AIMS: The present study aimed to isolate and characterize chemical compounds from Anthocephalus cadamba Miq. bark and evaluate their anticancer activity by in silico, molecular docking, and in vitro studies. BACKGROUND: Anthocephalus cadamba is a traditionally used Indian medicinal plant. The anticancer and phytochemical properties of this plant remain unexplored except for a few studies. OBJECTIVES: The objective of the study was to evaluate the antiproliferative activity of extract and fractions against breast cancer and prostate cancer cell lines and isolate and characterize active compounds from bio-active guided fractions. Moreover, the anticancer activity of isolated compounds against breast and prostate cancer cell lines was also evaluated, in addition to in silico and molecular docking interactions of isolated compounds with VEGFR2 and PDGFRα target proteins. METHODS: The compounds were isolated and purified with the help of repeated column chromatography, and spectral techniques, such as 1D, 2D NMR, and GC-MS/MS, were used to identify and elucidate the structure of the compounds. Moreover, prediction of activity spectra for substances, physiochemical properties, bioactivity radar prediction, bioactivity score, natural-product likeness, ADME, and toxicity parameters of isolated compounds (AC-1 to AC-4) was performed through various in-silico databases and servers. To evaluate the docking interaction profile and binding energies of compounds, three docking tools were utilized, such as AutoDock, AutoDock Vina, and iGEMDOCK, against two targets VEGFR2 and PDGFRα. MD simulation was performed through ligand and receptor molecular dynamic server (LARMD). RESULTS: It was found that the A. cadamba bark chloroform fraction demonstrated a significant inhibitory effect against MDA-MB-231, MCF-7, and PC-3 cells in a dose-time-dependent manner. The bioassay-guided isolation afforded four molecules AC-1 to AC-4 from chloroform fraction. Moreover, the GC-MS/MS profiling identified fourteen new molecules which were not reported earlier from A. cadamba. The in-silico study showed that the isolated compounds (AC-1 to AC-4) followed Lipinski's rule and had good oral bioavailability. While compound AC-4 had positive bioactivity scores except for kinase inhibitor activity. The ADMET profiling revealed that AC-4 was non-toxic and easily absorbed in the human intestine, and transportable in the blood-brain barrier compared to AC-1, AC-2, AC-3, and standard drug doxorubicin. Molecular docking and MD simulation assessment also signified AC-4 anticancer activity with dual inhibitory action against the target proteins VEGFR2 and PDGFRα amongst the studied compounds. The in vitro cell viability assay of isolated compounds demonstrated that AC-1 showed IC50 (µg/mL) value of 34.96 ±3.91, 47.76±3.80 69.1±4.96, AC-2; 68.26±4.22, 54.03±5.14, >100, AC-3; 35.34±4.14, 51.5±51.5, 70.8±5.25 and AC-4; 44.2±3.57, 24.2±2.67, 51.2±2.54 for MDA-MB-231, MCF-7, and PC-3 cancer cell lines, respectively and compared with standard drug doxorubicin. Moreover, fluorescence microscopy confirmed the apoptogenic property of compounds. We also found that AC-4 exhibited significant intracellular ROS production in breast cancer cells, thereby inducing apoptosis and eventually cell death. CONCLUSION: In conclusion, A. cadamba afforded four pure molecules AC-1 to AC-4 with the identification of fourteen new compounds. The entire in-silico studies concluded that the AC-4 compound had better oral bioavailability, bioactivity score, and ADMET profile among studied molecules. Molecular docking analysis and MD simulation also supported AC-4 dual inhibitory action against both VEGFR2 and PDGFRα receptors. Moreover, the isolated molecules AC-1, AC-2, AC-3, and AC-4 were found to be active against MDA-MB-231, MCF-7, and PC-3 cancer cells. The molecule AC-4 was found to induce ROS-mediated apoptosis in breast cancer cells. It was found that the anticancer inhibitory potentiality of AC-4 is directed to its molecular stereochemistry which specifically binds to the target proteins of breast cancer cells with no toxicological effect. Therefore, AC-4 is suggested to be an effective aspirant for novel drug design and discovery.

The effects of saffron (Crocus sativus L.) in conjunction with concurrent training on body composition, glycaemic status, and inflammatory markers in obese men with type 2 diabetes mellitus: A randomized double-blind clinical trial.

AIMS: Chronic inflammation is one of the major challenges in the management of obesity and type 2 diabetes mellitus (T2DM). Our primary aim was to assess the anti-inflammatory effects of Saffron (Crocus sativus L.) supplementation and concurrent training in obese men with T2DM. METHODS: Sixty obese men with T2DM (age = 39 ± 5 years; body mass = 93.9 ± 6 kg) were randomly assigned to four groups; concurrent training + placebo (CT; n = 15), saffron supplementation (S; n = 15), concurrent training + saffron supplementation (CTS; n = 15), or control (CON; n = 15). The participants in the CT group performed concurrent training (resistance + aerobic) three times per week for 12 weeks and received daily one pill of placebo (maltodextrin); the participants in the S group supplemented with one pill of 100 mg of saffron daily, and the participants in the CTS group participated in both saffron and training intervention while CON group continued regular lifestyle (no training and no supplementation). Inflammatory markers, body composition (evaluated by a multi-frequency bioelectrical impedance device; Jawon X-Contact 356), and metabolic profile were evaluated before and after interventions. RESULTS: All three interventions significantly (P < .05) decreased TNF-α (CT = -4.22, S = -1.91, CTS = -9.69 pg/mL), hs-CRP (CT = -0.13, S = -0.1, CTS = -0.32 ng/mL), IL-6 (CT = -6.84, S = -6.36, CTS = -13.55 pg/mL), IL-1ß (CT = -8.85, S = -6.46, CTS = -19.8 pg/mL), FBG (CT = -6.97, S = -2.45, CTS = -13.86 mg/dL), insulin (CT = -0.13, S = -0.03, CTS = -0.21 mU/L), HOMA-IR (CT = -0.12, S = -0.04, CTS = -0.21), HbA1c (CT = -0.17, S = -0.11, CTS = -0.26%), and increased IL-10 (CT = 1.09, S = 0.53, CTS = 2.27 pg/mL) concentrations. There was a positive correlation between changes in BFP with hs-CRP, IL-6, IL-1ß and TNF-α, and IL-10 concentrations across the intervention groups. Additionally, significant differences were observed between the changes for all variables in the CTS group compared to CT, S and CON groups (P < .05). CONCLUSION: It seems that an interaction of saffron supplementation and concurrent training has more efficient effects on anti-inflammatory status compared to saffron supplementation or concurrent training alone.

Effect of Cornus mas L. fruit extract on lipid accumulation product and cardiovascular indices in patients with non-alcoholic fatty liver disease: A double-blind randomized controlled trial.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with high risk of cardiovascular diseases. The experimental studies have suggested that Cornus mas L. (cornelian cherry) fruit can improve cardiovascular risk factors. We designed a study to investigate the effect of cornelian cherry fruit extract on cardiovascular outcomes in patients with NAFLD. METHODS: We conducted a double-blind, randomized controlled trial. Fifty patients with NAFLD were randomly assigned into the treatment and the control groups. The treatment group received 20 cc/d cornelian cherry fruit extract as liquid form and the control group received 20 cc/d placebo for 12 weeks. The primary outcomes included lipid accumulation product (LAP), atherogenic index of plasma (AIP), Castelli risk index I (CRI-I), CRI-II and atherogenic coefficient (AC). RESULTS: At the baseline, there was no significant difference between two groups in values of LAP, AIP, CRI-I, CRI-II and AC. After the intervention, no significant change was found in the treatment group compared to the control group in LAP (-0.64 (-6.25 to 8.29) vs. 0.0 (-8.66 to 19.01); P = 0.91), AIP (0.0 ± 0.08 vs. 0.0 ± 0.1; P = 0.84), CRI-I (-0.18 ± 0.63 vs. -0.31 ± 0.49; P = 0.42), CRI-II (-0.23 ± 0.56 vs. -0.15 ± 0.32; P = 0.52) and AC (-0.18 ± 0.63 vs. -0.31 ± 0.49; P = 0.42). CONCLUSION: Cornelian cherry fruit extract has no effect on cardiovascular outcomes. Further studies with longer intervention durations are needed.

The effect of L-carnitine supplementation on insulin resistance, sex hormone-binding globulin and lipid profile in overweight/obese women with polycystic ovary syndrome: a randomized clinical trial.

PURPOSE: Polycystic ovary syndrome (PCOS) is a common endocrine disorder among reproductive-age women. Insulin resistance and dyslipidemia are linked to PCOS. L-Carnitine supplementation as a management strategy for women with PCOS has been proposed. The effect of L-carnitine supplementation on insulin resistance, sex hormone-binding globulin (SHBG) and lipid profile in overweight/obese women with PCOS was investigated. METHODS: This randomized, double-blind, controlled clinical trial, was conducted on 62overweight/obese women with PCOS. Participants were randomly assigned into two groups to receive 1000 mg/day L-carnitine or placebo (1000 mg starch) for 12 weeks. RESULTS: L-Carnitine supplementation compared to the placebo showed a significant improvement in insulin [- 0.7 (- 7.3 to 4.0) vs. 0.7 (- 3.0 to 5.2); P = 0.001], homeostatic model assessment for insulin resistance [- 0.4 (- 1.7 to 1.1) vs. 0.0 (- 0.7 to 1.3); P = 0.002], quantitative insulin sensitivity check index (+ 0.01 ± 0.02 vs. - 0.01 ± 0.01; P = 0.02) and a non-significant change toward improvement in SHBG (+ 11.5 ± 40.2 vs. - 3.2 ± 40.2; P = 0.2). However, there was no significant differences between the two groups in serum levels of fasting plasma glucose, total cholesterol, triglyceride, low density lipoprotein-cholesterol and high density lipoprotein cholesterol (P > 0.05). CONCLUSION: 12-week L-carnitine supplementation in overweight or obese women with PCOS ameliorate insulin resistance, but has no effect on SHBG and lipid profile. Studies with higher dosages and duration of L-carnitine intake are required. The trial was registered on 30 December 2019 at Iranian Registry of Clinical Trials IRCT20191016045131N1.

BACKGROUND: Patients with non-alcoholic fatty liver disease (NAFLD) as well as type 2 diabetes mellitus (T2DM) are at increased risk for cardiovascular diseases (CVD). Omega-3 supplementation has been proposed as a possible strategy for management of cardiometabolic risk. Cardiometabolic indices can predict and evaluate the cardiometabolic risk. AIMS: We investigated the effect of omega-3 supplementation on accurate and available cardiometabolic indices including atherogenic index of plasma (AIP), Castelli risk index I, Castelli risk index II and atherogenic coefficient (AC) in diabetic patients with NAFLD. METHODS: We conducted a double-blind, randomized controlled trial (RCT) for 12 weeks. From August 2016 to March 2017, the subjects referred to Faghihi hospital in Shiraz, Iran, were recruited. Sixty diabetic patients with NAFLD were randomly assigned into the omega-3 (2000 mg/d omega-3 capsule contained 360 mg/d eicosapentaenoic acid and 240 mg/d docosahexaenoic acid) and the placebo (liquid paraffin) groups using computer-generated random number table. RESULTS: Omega-3 supplementation compared to the placebo had no significant effect on AIP (- 0.11 ± 0.20 vs. -0.03 ± 0.16; P = 0.11), Castelli risk index I (- 0.25 ± 0.6 vs. -0.07 ± 0.7; P = 0.42), Castelli risk index II (- 0.24 ± 0.5 vs. -0.14 ± 0.5; P = 0.63) and AC (- 0.25 ± 0.6 vs. -0.07 ± 0.7; P = 0.42). After adjusting for confounding factors, the findings remained without change. CONCLUSION: Omega-3 supplementation (2000 mg/d) for 12 weeks has no effect on cardiometabolic risk. It seems, higher doses of omega-3 can improve cordiometabolic risk. The trial was registered at Iranian Registry of Clinical Trials IRCT2016102530489N1.

Effect of l-carnitine supplementation on liver fat content and cardiometabolic indices in overweight/obese women with polycystic ovary syndrome: A randomized controlled trial.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine disorder among reproductive-age women, and is associated with cardiovascular diseases as well as non-alcoholic fatty liver disease. The recent evidence suggested the beneficial effects of l-carnitine in women with PCOS. OBJECTIVE: The present study aimed to investigate the effect of l-carnitine supplementation on liver fat content and cardiometabolic outcomes in overweight/obese women with PCOS. METHODS: The present study was designed as a 12-week double-blind, randomized controlled clinical trial. Sixty-two overweight/obese women with PCOS were assigned into the treatment (received 1000 mg/d l-carnitine capsule) and the control (received placebo capsule) groups. The outcomes included lipid accumulation product (LAP), atherogenic index of plasma (AIP), atherogenic coefficient (AC) and Castelli II indices. RESULTS: At the end of the trial, there was no significant difference between the treatment and the control groups in terms of LAP (-1.1 vs. -4.0; P = 0.45), AIP (0.0 vs. -0.09; P = 0.14), AC (-0.2 vs. -0.8; P = 0.06) and Castelli II index (-0.2 vs. -0.6; P = 0.07) after controlling the mean change of waist circumference. CONCLUSION: l-carnitine supplementation for 12 weeks has no beneficial effect on liver fat content and cardiometabolic outcomes in overweight or obese women with PCOS.

Antioxidant, antibacterial and antifungal potential study of Salvia macrosiphon Boiss. stem extracts.

The aim of present research work was to evaluate the Salvia macrosiphon Boiss. of Lamiaceae (mint family), using biochemical and biological assays. Plant's phytochemicals extraction was performed in methanol, butanol and water by mechanical shaking process. TPC and TFC were determined by Folin-Ciocalteu and aluminum chloride colorimetric procedures, respectively. The highest TPC (99.61±3.45 mg GAE/g) and TFC (234.72±7.12mg CE/g) were obtained in butanol and methanol, respectively. Regarding the antioxidant potential methanol extract showed the highest DPPH° scavenging potential (78.0±2.0%) and reducing activity (0.923±0.020 absorbance). The antibacterial activity of butanol extract against P. aeruginosa were found highest (ZOI = 23±2.00 mm). Antifungal study of methanol extract showed the ZOI (11 ±0.67mm) against F. brachygibbosum. The results revealed that the methanol stem extract of S. macrosiphon bear significant medicinal value and could be used for formulating phytomedicines and food preservers.

Role of Glycation in Type 2 Diabetes Mellitus and Its Prevention through Nymphaea Species.

The dysregulation of glucose metabolism that includes the modification of biomolecules with the help of glycation reaction results in the formation of advanced glycation end products (AGEs). The formation of AGEs may activate receptors for advanced glycation end products which induce intracellular signaling, ultimately enhancing oxidative stress, a well-known contributor to type 2 diabetes mellitus. In addition, AGEs are possible therapeutic targets for the treatment of type 2 diabetes mellitus and its complications. This review article highlights the antioxidant, anti-inflammatory, and antidiabetic properties of the Nymphaea species, and the screening of such aquatic plants for antiglycation activity may provide a safer alternative to the adverse effects related to glucotoxicity. Since oxidation and glycation are relatively similar to each other, therefore, there is a possibility that the Nymphaea species may also have antiglycating properties because of its powerful antioxidant properties. Herbal products and their derivatives are the preeminent resources showing prominent medicinal properties for most of the chronic diseases including type 2 diabetes mellitus. Among these, the Nymphaea species has also shown elevated activity in scavenging free radicals. This species has a load of phytochemical constituents which shows various therapeutic and nutritional value including anti-inflammatory and antioxidant profiles. To the best of our knowledge, this is the first article highlighting the possibility of an antiglycation value of the Nymphaea species by inhibiting AGEs in mediation of type 2 diabetes mellitus. We hope that in the next few years, the clinical and therapeutic potential may be explored and highlight a better perspective on the Nymphaea species in the inhibition of AGEs and its associated diseases such as type 2 diabetes mellitus.

Effect of omega-3 supplementation on fatty liver and visceral adiposity indices in diabetic patients with non-alcoholic fatty liver disease: A randomized controlled trial.

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) as the most common chronic liver disease is closely linked to type 2 diabetes mellitus (T2DM). Omega-3 supplementation has been proposed as a strategy to manage T2DM and NAFLD. The present study aimed to investigate the effect of omega-3 supplementation on fatty liver index, lipid accumulation product and visceral adiposity index in diabetic patients with NAFLD. METHODS: In this 12-week double-blind, randomized controlled clinical trial, sixty diabetic patients with NAFLD were randomly assigned into the omega-3 and placebo groups for 12 weeks. The omega-3 group received 2000 mg/d omega-3 as capsule. RESULTS: Fifty-six participants completed the study. No significant difference was found between the two groups in the terms of fatty liver index, lipid accumulation product and visceral adiposity index at the baseline. Omega-3 supplementation compared with the placebo led to a significant improvement in fatty liver index (-3.6 ± 12.1 vs. 0.9 ± 8.9; P = 0.04), lipid accumulation product (-14.2 ± 27.9 vs. 8.0 ± 26.3; P = 0.002) and visceral adiposity index (-0.5 ± 0.9 vs. 0.0 ± 0.8; P = 0.01). CONCLUSION: Omega-3 supplementation for 12 weeks improves fatty liver index, lipid accumulation product and visceral adiposity index. The study protocol was registered under Iranian Registry of Clinical Trials identifier number IRCT2016102530489N1.

Influence of flaxseed with rumen undegradable protein level on milk yield, milk fatty acids and blood metabolites in transition ewes.

An experiment was conducted to determine the effects of two levels of rumen undegradable protein (RUP) without or with whole or extruded flaxseed on milk yield, milk component, milk fatty acids (FAs) profile and plasma metabolites in transition ewes. Three weeks before and after lambing, seventy-two Baluchi ewes were used in a completely randomized design with a 3 × 2 factorial arrangement of treatments. The treatments contained 1) no flaxseed + 20% RUP (no flaxseed, low RUP [NFLR]); 2) no flaxseed + 40% RUP (no flaxseed, high RUP [NFHR]); 3) 10% whole flaxseed + 20% RUP (whole flaxseed, low RUP [WFLR]); 4) 10% whole flaxseed + 40% RUP (whole flaxseed, high RUP [WFHR]); 5) 10% extruded flaxseed + 20% RUP (extruded flaxseed, low RUP [EFLR]), and 6) 10% extruded flaxseed + 40% RUP (extruded flaxseed, high RUP [EFHR]). Ewes fed 10% extruded flaxseed exhibited higher (p < 0.001) dry matter intake (DMI) and colostrum yield (p < 0.1) compared to other treatments. Two types of flaxseed and RUP levels had no significant effect on milk yield, but milk fat and protein contents decreased and increased in diets containing 40% RUP, respectively. Ewes fed extruded flaxseed produced milk with lower concentrations of saturated fatty acids (SFA) and higher α-linolenic and linoleic acids and also polyunsaturated fatty acids (PUFA) compared to other groups (p < 0.05). During post-lambing, the ewes fed diets containing flaxseed exhibited higher concentration of serum non-esterified FAs (NEFA) compared to diets without flaxseed (p < 0.01). The concentration of serum ß-hydroxybutyric acid (BHBA) decreased in the diets containing flaxseed types at pre-lambing, but increased in diets containing extruded flaxseed at post-lambing (p < 0.01). The serum glucose concentration of ewes (pre and post-lambing) which consumed diets containing extruded flaxseed or 40% RUP increased, but blood urea concentration was elevated following supplementation of diet with whole flaxseed or 40% RUP (p < 0.001). In conclusion, utilization of 10% extruded flaxseed in the diets of transition ewes had positive effects on animal performance with favorable changes in milk FAs profile. However, there is no considerable advantage to supply more than 20% RUP level in the diet of transition dairy sheep.
