The effects of nonsoy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin in overweight/obese adults: A systematic review and meta-analysis of randomized controlled trials.

Nonsoy legumes offer many health benefits, including improved arterial function, reduced cholesterol levels, and better management of cardiovascular diseases and type 2 diabetes. This systematic review and meta-analysis aim to clarify the inconclusive findings from randomized controlled trials (RCTs) by comprehensively evaluating the effects of nonsoy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin. The search encompassed databases up to January 2024, including PubMed, EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL to retrieve all RCTs examining the effects of nonsoy legumes on inflammatory biomarkers or Adiponectin. The effect sizes quantified as mean differences (MD) and standard deviations (SD) of outcomes, and an overall effect estimate was derived using a random-effects model. RCTs examining serum levels of C-reactive protein (CRP), Interleukin-6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α), Interleukin-1ß (IL-1ß), and Adiponectin were included in the final meta-analysis. Results revealed that consumption of nonsoy legumes increased Adiponectin serum levels (P=.0017) and reduced IL-1ß serum levels (P<.0001). However, it may not significantly affect CRP (P=.2951), IL-6 (P=.2286), and TNF-α (P=.6661) levels. Subgroup analyses showed that nonsoy legumes consumption significantly decreased TNF-α serum levels in studies involving healthy participants. Additionally, sensitivity analysis using the leave-one-out method suggested a potential significant reduction in serum levels of IL-6. This study indicates that consuming nonsoy legumes can increase levels of Adiponectin and decrease serum levels of IL-1ß in overweight or obese adults.

Exploring mitochondrial DNA copy number in circulating cell-free DNA and extracellular vesicles across cardiovascular health status: A prospective case-control pilot study.

Cardiovascular disease (CVD) is a leading global cause of mortality, difficult to predict in advance. Evidence indicates that the copy number of mitochondrial DNA (mtDNAcn) in blood is altered in individuals with CVD. MtDNA released into circulation may act as a mediator of inflammation, a recognized factor in the development of CVD, in the long distance. This pilot study aims to test if levels of mtDNAcn in buffy coat DNA (BC-mtDNA), in circulating cellfree DNA (cf-mtDNA), or in DNA extracted from plasma extracellular vesicles (EV-mtDNA) are altered in CVD patients and if they can predict heart attack in advance. A group of 144 people with different CVD statuses (50 that had CVD, 94 healthy) was selected from the LifeLines Biobank according to the incidence of new cardiovascular event monitored in 6 years (50 among controls had heart attack after the basal assessment). MtDNAcn was quantified in total cf-DNA and EV-DNA from plasma as well as in buffy coat. EVs have been characterized by their size, polydispersity index, count rate, and zeta potential, by Dynamic Light Scattering. BC-mtDNAcn and cf-mtDNAcn were not different between CVD patients and healthy subjects. EVs carried higher mtDNAcn in subject with a previous history of CVD than controls, also adjusting the analysis for the EVs derived count rate. Despite mtDNAcn was not able to predict CVD in advance, the detection of increased EV-mtDNAcn in CVD patients in this pilot study suggests the need for further investigations to determine its pathophysiological role in inflammation.

Plant-Derived Epi-Nutraceuticals as Potential Broad-Spectrum Anti-Viral Agents.

Although the COVID-19 pandemic appears to be diminishing, the emergence of SARS-CoV-2 variants represents a threat to humans due to their inherent transmissibility, immunological evasion, virulence, and invulnerability to existing therapies. The COVID-19 pandemic affected more than 500 million people and caused over 6 million deaths. Vaccines are essential, but in circumstances in which vaccination is not accessible or in individuals with compromised immune systems, drugs can provide additional protection. Targeting host signaling pathways is recommended due to their genomic stability and resistance barriers. Moreover, targeting host factors allows us to develop compounds that are effective against different viral variants as well as against newly emerging virus strains. In recent years, the globe has experienced climate change, which may contribute to the emergence and spread of infectious diseases through a variety of factors. Warmer temperatures and changing precipitation patterns can increase the geographic range of disease-carrying vectors, increasing the risk of diseases spreading to new areas. Climate change may also affect vector behavior, leading to a longer breeding season and more breeding sites for disease vectors. Climate change may also disrupt ecosystems, bringing humans closer to wildlife that transmits zoonotic diseases. All the above factors may accelerate the emergence of new viral epidemics. Plant-derived products, which have been used in traditional medicine for treating pathological conditions, offer structurally novel therapeutic compounds, including those with anti-viral activity. In addition, plant-derived bioactive substances might serve as the ideal basis for developing sustainable/efficient/cost-effective anti-viral alternatives. Interest in herbal antiviral products has increased. More than 50% of approved drugs originate from herbal sources. Plant-derived compounds offer diverse structures and bioactive molecules that are candidates for new drug development. Combining these therapies with conventional drugs could improve patient outcomes. Epigenetics modifications in the genome can affect gene expression without altering DNA sequences. Host cells can use epigenetic gene regulation as a mechanism to silence incoming viral DNA molecules, while viruses recruit cellular epitranscriptomic (covalent modifications of RNAs) modifiers to increase the translational efficiency and transcript stability of viral transcripts to enhance viral gene expression and replication. Moreover, viruses manipulate host cells' epigenetic machinery to ensure productive viral infections. Environmental factors, such as natural products, may influence epigenetic modifications. In this review, we explore the potential of plant-derived substances as epigenetic modifiers for broad-spectrum anti-viral activity, reviewing their modulation processes and anti-viral effects on DNA and RNA viruses, as well as addressing future research objectives in this rapidly emerging field.

Reducing the effect of beauvericin on neuroblastoma SH-SY5Y cell line by natural products.

In the present work, different natural compounds from coffee by-product extracts (coffee silverskin and spent coffee) rich in polyphenols, was investigated against beauvericin (BEA) induced-cytotoxicity on SH-SY5Y cells. Spent coffee arise as waste products through the production of instant coffee and coffee brewing; while the silverskin is a tegument which is removed and eliminated with toasting coffee grains. First of all, polyphenol extraction methods, measurement of total polyphenols content and its identification were carried out. Afterwards evaluating in vitro effects with MTT assay on SH-SY5Y cells of coffee by-product extracts and mycotoxins at different concentrations and exposure times was performed. TPC in silverskin coffee by-product extracts was >10 times higher than in spent coffee by-product extracts. Chlorogenic acid was the majority polyphenol detected. Viability for BEA reached IC50 values at 72h (2.5 µM); boiling water silverskin coffee extract reached the highest viability also in pre-treatment BEA exposure and compared with MeOH and MeOH:H2O (v/v, 50:50) extracts. These results in SH-SY5Y cells highlight the use of such residues as supplements or bioactive compounds in the future.
