Amino Acid Profiles and Nutritional Evaluation of Fresh Sweet–Waxy Corn from Three Different Regions of China. Nutrients 2022; 14:nu14193887. [PMID: 36235541 PMCID: PMC9572857 DOI: 10.3390/nu14193887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 09/15/2022] [Accepted: 09/16/2022] [Indexed: 11/16/2022] Open
Abstract
This study conducted a comparative analysis of the amino acid compositions of Chinese Huangnuo 9 fresh sweet–waxy corn from three different provinces in China—Inner Mongolia, Jilin, and Heilongjiang Province. Moreover, we established a nutritive evaluation system based on amino acid profiles to evaluate, compare, and rank the fresh sweet–waxy corn planted in different regions. A total of 17 amino acids were quantified, and the amino acid composition of fresh sweet–waxy corn was analyzed and evaluated. The amino acid quality was determined by the amino acid pattern spectrum, chemical evaluations (including CS, AAS, EAAI, BV, U(a,u), NI, F, predict PER, and PDCAAS), flavor evaluation, amino acid matching degree evaluation, and the results of the factor analysis. The results showed that the protein content of fresh corn 1–1 from Inner Mongolia was the highest (40.26 ± 0.35 mg/g), but the factor analysis results, digestion, and absorption efficiency of fresh corn 1–2 were the best. The amino acid profile of fresh corn 1–1 was closest to each evaluation’s model spectrum. The results of the diversity evaluations in fresh corn 3–2 were the best, and fresh corn 3–3 had the most essential amino acid content. A total of 17 amino acids in fresh corn were divided into three principal component factor analyses: functional principal components (Leu, Pro, Glu, His, Ile, Ser, Met, Val, Tyr, Thr), regulatory principal components (Lys, Gly, Ala, Asp, Arg, Trp), and protection principal components (Phe). The scores of the three principal components and the comprehensive score in fresh corn 1–2 were all the highest, followed by 3–3 and 1–1. The amino acid nutritional values of fresh corn 1–2 were the highest in 12 samples.

Incorporation of Limosilactobacillus fermentum UCO-979C with Anti- Helicobacter pylori and Immunomodulatory Activities in Various Ice Cream Bases. Foods 2022; 11:foods11030333. [PMID: 35159484 PMCID: PMC8834266 DOI: 10.3390/foods11030333] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 01/17/2022] [Accepted: 01/17/2022] [Indexed: 12/15/2022] Open
Abstract
Limosilactobacillus fermentum UCO-979C is a probiotic strain possessing anti-Helicobacter pylori and immunomodulatory activity. The aim of this work was to examine if this strain maintains its probiotic properties and its viability when added to dairy-based ice creams (cookies and cream, Greek yogurt, and chocolate with brownie) or to fruit-based ice creams (pineapple and raspberry) stored at −18 °C for 90 days. The probiotic anti-H. pylori activity using the well diffusion test, its immunomodulatory activity was measured using transforming growth factor beta 1 (TGF-β1) cytokine production by human gastric adenocarcinoma (AGS) cells, and its viability was measured using the microdrop technique. Assays were performed in triplicate. The L. fermentum UCO-979C strain maintained strong anti-H. pylori activity in dairy-based ice creams and mild activity in fruit-based ice cream. The production of pro-inflammatory cytokine TGF-β1 on AGS cells was higher in the probiotic recovered from Greek yogurt ice cream, maintaining a viability exceeding 107 colony-forming units/mL. The addition of the probiotic to ice creams did not significantly influence the physicochemical properties of the product. These data show the great potential of the L. fermentum UCO-979C strain in producing probiotic dairy-based and fruit-based ice creams.

Development of nano-encapsulated green tea catechins: Studies on optimization, characterization, release dynamics, and in-vitro toxicity. J Food Biochem 2021; 45:e13951. [PMID: 34569069 DOI: 10.1111/jfbc.13951] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 09/02/2021] [Accepted: 09/05/2021] [Indexed: 12/15/2022]
Abstract
Green tea (Camelia sinesis) has been acknowledged for plethora of pharmacological activities attributed by green tea catechins (GTC), however, poor bioavailability, short half-life and stability issues hamper its use as a therapeutic agent. Chitosan and sodium -tripolyphosphate were used to encapsulate GTC, which reduced its degradation in gastro-intestinal tract. The average size, zeta potential, and encapsulation efficiency of nano-encapsulated epigallocatechin-3-gallate (EGCG) rich GTC were observed as 250 nm, +49.8 mV, and 87%, respectively. The morphological and physico-chemical characterizations affirmed the size, stability, and encapsulation efficacy of nano-encapsulated green tea catechins. The In-vitro simulated release model showed the release of GTC in the intestinal phase via zero order kinetics. Cell viability studies were conducted on PC12 cell line to validate safety efficacy of nanoencapsulated GTC. Moreover, the study concluded that stability, bioavailability and bioactivity of EGCG was improved by nanoencapsulation of GTC, thereby rendering it a potent nanoceutical for clinical implications. PRACTICAL APPLICATIONS: Green tea catechin has enormous health endorsing activities. One of the major potentials of GTC is its antioxidant activity that plays a promising role in the prevention of various lethal disorders. In the present study, nanoencapsulation is used as a potential approach to improve the low bioavailability of green tea catechin. The results enlightened that nanoencapsulation of green tea catechin could be useful for improving the stability of green tea catechin in the GI tract as well as its bioaccessibility. Henceforth, this strategy restores the stability and bioavailability of green tea catechin that could be practically implied as a nutraceutical in the food and pharmaceutical industry as it can enhance the biological activity of catechins in catechin rich green tea-related products.

Biol Trace Elem Res 2021; 199:1345-1355.

Abstract
In the present study, protective effects of Ananas comosus i.e., pineapple pulp (PA) against cobalt chloride (CoCl2)‑induced hypoxia in Caco-2 cells were evaluated. PA reduces levels of lipid peroxidation, reactive oxygen and nitrogen species. It was proved to be cytoprotective and increased anti-oxidant activity against CoCl2-induced hypoxia. The inference drawn from this experiment was CoCl2-induced hypoxia that regulates hypoxia-inducible factor-1 (HIF-1), a transcription factor. It was also confirmed that PA pre-treatment inhibited the expression of HIF-1α, thereby downregulating the hypoxia-associated gene/protein expressions such as GLUT-1, VEGF, ANG and FGF. Finally, supplementation of PA could help in snow-balling the digestive hormones like leptin and CCK in hypoxic conditions. Therefore, this report provides substantial proof of reducing the hypoxia-induced loss of appetite at high-altitude environments. Graphical Abstract.

Aegle marmelos extract rich in marmelosin exacted ameliorative effect against chromium-induced oxidative stress and apoptosis through regulation of Gadd45 in HepG2 cell line. J Food Biochem 2021; 45:e13704. [PMID: 33719131 DOI: 10.1111/jfbc.13704] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 02/03/2021] [Accepted: 03/02/2021] [Indexed: 11/28/2022]
Abstract
Hexavalent chromium [Cr (VI)] is highly toxic compared to other valence states of chromium. In the process of metabolic reduction, Cr (VI) converts to trivalent chromium. Aegle marmelos (Bael), a sacred plant of India and its fruits are being consumed as traditional formulations against various diseases such as ulcer, gastric mucosal damage, inflammations, febrile delirium, acute bronchitis, anxiety, etc. The present study assessed the protective effects of marmelosin (MAR) from Aegle marmelos against K2 Cr2 O7 -induced toxic effects in HepG2 cell line through its antiapoptotic mechanism. Results of the study revealed that pretreatment of MAR ameliorated cell viability, mitochondrial damage, and DNA damage induced by K2 Cr2 O7 in HepG2 cell line as evidenced by cell morphology, MTT, LDH, and MMP assays. Pretreatment of MAR attenuated K2 Cr2 O7 -induced oxidative stress by downregulating intracellular ROS and RNS. Further, pretreatment of MAR significantly downregulated K2 Cr2 O7 -induced apoptotic markers, such as Bax, Caspase 3, and Gadd45. Our results suggested that application of marmelosin could be beneficial in ameliorating chromium-induced apoptotic cell death by suppressing oxidative stress and regulating excessive DNA damage. PRACTICAL APPLICATIONS: The study focused on protective mechanism of marmelosin from Aegle marmelos against chromium-induced oxidative stress for the first time. In this research, we reported that marmelosin effectively ameliorated K2 Cr2 O7 -induced morphological changes such as oxidative stress and apoptotic cell death by regulating Gadd45, Bcl-2, Bax, and Caspase 3 gene expressions, and inhibition of intracellular ROS and RNS. The study provides a better understanding of the pharmacological mechanisms of Aegle marmelos and its bioactive compound, that is, marmelosin in the management of intoxication of heavy metals associated with excessive DNA damage.

Abstract
The chemical elements are the "conserved principles" or "kernels" of chemistry that are retained when substances are altered. Comprehensive overviews of the chemistry of the elements and their compounds are needed in chemical science. To this end, a graphical display of the chemical properties of the elements, in the form of a Periodic Table, is the helpful tool. Such tables have been designed with the aim of either classifying real chemical substances or emphasizing formal and aesthetic concepts. Simplified, artistic, or economic tables are relevant to educational and cultural fields, while practicing chemists profit more from "chemical tables of chemical elements." Such tables should incorporate four aspects: (i) typical valence electron configurations of bonded atoms in chemical compounds (instead of the common but chemically atypical ground states of free atoms in physical vacuum); (ii) at least three basic chemical properties (valence number, size, and energy of the valence shells), their joint variation across the elements showing principal and secondary periodicity; (iii) elements in which the (sp)8, (d)10, and (f)14 valence shells become closed and inert under ambient chemical conditions, thereby determining the "fix-points" of chemical periodicity; (iv) peculiar elements at the top and at the bottom of the Periodic Table. While it is essential that Periodic Tables display important trends in element chemistry we need to keep our eyes open for unexpected chemical behavior in ambient, near ambient, or unusual conditions. The combination of experimental data and theoretical insight supports a more nuanced understanding of complex periodic trends and non-periodic phenomena.
