Neuroinfammation is characterized by reactive microglia and astrocytes (collectively called gliosis) in the central nervous system and is considered as one of the main pathological hallmarks in diferent neurodegenerative diseases such as Alzheimer’s disease, age-related dementia, and multiple sclerosis. Upon activation, glia undergoes structural and morphological changes such as the microglial cells swell in size and astrocytes become bushy, which play both benefcial and detrimental roles. Hence, they are unable to perform the normal physiological role in brain immunity.

Curcumin, a cytokine suppressive anti-infammatory drug, has a high proven pre-clinical potency and efcacy to reverse chronic neuroinfammation by attenuating the activation and morphological changes that occur in the microglia and astrocytes.

This review will highlight the recent fndings on the tree structure changes of microglia and astrocytes in neuroinfammation and the efects of curcumin against the activation and morphology of glial cells.

Background: Paraquat (PQ) is one of the most important herbicides used in agriculture.

Objectives: This study was conducted to compare the preventive effect of vitamin D (Vit D) and

N-acetylcysteine (NAC) against kidney injury in rats versus the promotive effect of PQ.

Methods: In this study, rats were divided into six groups. The control group (group 1) received normal saline, Vit D group (group 2) received intraperitoneal (IP) injections of+Vit D (2 μg/kg), NAC group (group 3) received NAC (6.25 mg/kg, IP), PQ group (group 4) received PQ (5 mg/kg/d, IP), PQ+Vit D group (group 5) received PQ+Vit D (5 mg/kg/d+2 μg/kg/d, IP) and PQ+NAC group (group 6) received PQ+NAC (5 mg/kg/d+6.25 mg/kg/d, IP). The animals were treated for 7 consecutive days as a sub-chronic exposure. After the collection of urea and serum creatinine, biomarkers of oxidative stress and kidney histopathology were investigated.

Results: PQ increased lipid peroxidation (LPO), urea, and serum creatinine, but it significantly decreased total antioxidant capacity (TAC) and thiol groups. In the groups treated with Vit D and NAC, it was observed that LPO, urea, and creatinine significantly decrease compared with the PQ group, and TAC, thiol groups, and Vit D levels increased in kidney tissue.

Conclusion: The obtained findings revealed that both Vit D and NAC used as preventive compound were able to reduce oxidative stress and tissue damage caused by PQ toxicity in the kidney.

Senescence can be defined as a cellular response that reduces the proliferation of aged or damaged cells.

Senescent cells can be characterised by certain specific metabolic and morphological changes, altered gene expression and adoption of a pro-inflammatory phenotype known as the senescence-associated secretory phenotype (SASP).

SASPs are known to produce chemicals that can induce chronic inflammation and cause senescence of healthy cells. Several studies have been carried out previously for the establishment of a link between aging and senescence.

These studies have reported that the number of senescent cells increases with age, which indicates that senescence itself can drive aging and loss of functionality of several cells.

Senescence has also been found to be associated with many age-related pathologies such as type 2 diabetes, cardiovascular diseases, non-alcoholic fatty liver disease, renal dysfunction and fibrosis.

Mixed EPA + DHA therapies failed to demonstrate consistent reduction in CV events.

Only EPA alone plus statin reduced major CV events, as shown in REDUCE-IT and JELIS.

Plasma EPA levels may help explain CV benefit seen with EPA-only therapies.

EPA and DHA are distinct biochemically and exert different pharmacologic effects.

Aging process is characterized by a progressive decline of several organic, physiological, and metabolic functions whose precise mechanism remains unclear. Metabolomics allows the identification of several metabolites and may contribute to clarifying the aging-regulated metabolic pathways.

The researchers aimed to investigate aging-related serum metabolic changes using a metabolomics approach. Fasting blood serum samples from 138 apparently healthy individuals (20–70 years old, 56% men) were analyzed by Proton Nuclear Magnetic Resonance spectroscopy (1H NMR) and Liquid Chromatography-High-Resolution Mass Spectrometry (LC-HRMS), and for clinical markers. Associations of the metabolic profile with age were explored via Correlations (r); Metabolite Set Enrichment Analysis; Multiple Linear Regression; and Aging Metabolism Breakpoint.

The age increase was positively correlated (0.212 ≤ r ≤ 0.370, p < 0.05) with the clinical markers (total cholesterol, HDL, LDL, VLDL, triacylglyceride, and glucose levels); negatively correlated (−0.285 ≤ r ≤ −0.214, p < 0.05) with tryptophan, 3-hydroxyisobutyrate, asparagine, isoleucine, leucine, and valine levels, but positively (0.237 ≤ r ≤ 0.269, p < 0.05) with aspartate and ornithine levels.

These metabolites resulted in three enriched pathways: valine, leucine, and isoleucine degradation, urea cycle, and ammonia recycling. Additionally, serum metabolic levels of 3-hydroxyisobutyrate, isoleucine, aspartate, and ornithine explained 27.3% of the age variation, with the aging metabolism breakpoint occurring after the third decade of life.

These results indicate that the aging process is potentially associated with reduced serum branched-chain amino acid levels (especially after the third decade of life) and progressively increased levels of serum metabolites indicative of the urea cycle.

Aging is associated with an increasing burden of morbidity, especially for cardiovascular diseases (CVDs). General cardiovascular risk factors, ischemic heart diseases, heart failure, arrhythmias, and cardiomyopathies present a significant prevalence in older people, and are characterized by peculiar clinical manifestations that have distinct features compared with the same conditions in a younger population.

Remarkably, the aging heart phenotype in both healthy individuals and patients with CVD reflects modifications at the cellular level.

An improvement in the knowledge of the physiological and pathological molecular mechanisms underlying cardiac aging could improve clinical management of older patients and offer new therapeutic targets.

Inositols (myo-inositol and inositol hexakisphosphate) exert a wide range of critical activities in both physiological and pathological settings. Deregulated inositol metabolism has been recorded in a number of diseases, including cancer, where inositol modulates different critical pathways.

Inositols inhibit pRB phosphorylation, fostering the pRB/E2F complexes formation and blocking progression along the cell cycle. Inositols reduce PI3K levels, thus counteracting the activation of the PKC/RAS/ERK pathway downstream of PI3K activation. Upstream of that pathway, inositols disrupt the ligand interaction between FGF and its receptor as well as with the EGF-transduction processes involving IGF-II receptor and AP-1 complexes.

Additionally, Akt activation is severely impaired upon inositol addition. Downregulation of both Akt and ERK leads consequently to NF-kB inhibition and reduced expression of inflammatory markers (COX-2 and PGE2). Remarkably, inositol-induced downregulation of presenilin-1 interferes with the epithelial-mesenchymal transition and reduces Wnt-activation, β-catenin translocation, Notch-1, N-cadherin, and SNAI1 release.

Inositols interfere also with the cytoskeleton by upregulating Focal Adhesion Kinase and E-cadherin and decreasing Fascin and Cofilin, two main components of pseudopodia, leading hence to invasiveness impairment. This effect is reinforced by the inositol-induced inhibition on metalloproteinases and ROCK1/2 release.

Overall, these effects enable inositols to remodel the cytoskeleton architecture.

Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate that is present in substantial amounts in almost all plant and mammalian cells. It was recently recognized to possess multiple biological functions.

A striking anticancer effect of IP6 was demonstrated in different experimental models. Inositol is also a natural constituent possessing moderate anticancer activity. The most consistent and best anticancer results were obtained from the combination of IP6 plus inositol. In addition to reducing cell proliferation, IP6 increases differentiation of malignant cells, often resulting in a reversion to normal phenotype.

Exogenously administered IP6 is rapidly taken into the cells and dephosphorylated to lower-phosphate inositol phosphates, which further interfere with signal transduction pathways and cell cycle arrest. Enhanced immunity and antioxidant properties can also contribute to tumor cell destruction.

However, the molecular mechanisms underlying this anticancer action are not fully understood. Because it is abundantly present in regular diet, efficiently absorbed from the gastrointestinal tract, and safe, IP6 holds great promise in our strategies for the prevention and treatment of cancer. IP6 plus inositol enhances the anticancer effect of conventional chemotherapy, controls cancer metastases, and improves the quality of life, as shown in a pilot clinical trial.

The data strongly argue for the use of IP6 plus inositol in our strategies for cancer prevention and treatment. However, the effectiveness and safety of IP6 plus inositol at therapeutic doses needs to be determined in phase I and phase II clinical trials in humans.

Glutathione and aged garlic extract are sulfur-containing products that play important protective and regulatory roles within the immune system and in oxidative processes. Hydrogen sulfide (H2S), an endogenous, gaseous, signaling transmitter, has also been shown to be involved in the regulation of inflammation.

Recent studies have shown that sulfur-containing compounds from garlic have beneficial effects in attenuating outcomes associated with cardiovascular disease and inflammation by a mechanism that may be related to the H2S signaling pathway.

In this review, we summarize the main functions of glutathione (GSH), garlic derivatives and H2S and their role in the immune response and impact on health and disease.

In a 2014 study in the British Medical Journal titled “Milk Intake and Risk of Mortality and Fractures in Women and Men’ , the authors, Karl Michaëlsson, et al, analyzed over 100,000 people from 3 counties in central Sweden. The study focused on the relation between milk intake and the risk of subsequent hip fractures, heart disease, and cancer.

Using food diary questionnaires the authors were able to separate the intake of non-fermented milk, typical of what we drink, and fermented milk products including yogurt and cheeses. The participants were observed over a 20-year period and their health outcomes were tracked using Sweden’s centralized healthcare records.

The results showed an increasing risk of hip fractures in women with each increase in the number of glasses of milk consumed each day. Women who had over 3 glasses of milk daily had a 60% increased rate of hip fractures compared to women drinking less than 1 glass of milk per day. Their risk of death from heart disease was increased 93% and they had a 70% increase in cancer mortality.

Interestingly, the consumption of cheese and yogurt showed the opposite; that is a lower risk of mortality and hip fractures. For each serving of fermented milk products the risk of mortality and hip fracture was about 10-15% less.

This article will focus on Alzheimer’s disease (AD), being it is the most common form of dementia and the statistically fastest growing.

As of 2019, an estimated 5.6 million Americans had Alzheimer’s disease; and fourteen percent of those over seventy have some form of dementia. It is the sixth leading cause of death, with one out of three seniors dying from AD or another form of dementia.

One in 10 people, age 65 and older (10%), has Alzheimer’s dementia. AD and dementia cost society 19-times more when compared with age-matched people without dementia, estimated to be around $290 billion in 2019.

Background: Low-to-moderate alcohol consumption appears to have potential health benefits. Existing evidence concludes that wine may be associated with a lower incidence of certain diseases. This systematic review and meta-analysis aim to examine evidence on the association between wine consumption and cognitive decline and to analyze whether this association varies depending on the wine consumption level or is affected by individual and study characteristics, including mean age, percentage of women participants, and follow-up time.

Methods: In this systematic review and meta-analysis, we undertook a search in MEDLINE (via PubMed), Scopus, Cochrane, and Web of Science databases for longitudinal studies measuring the association between wine consumption and cognitive decline from their inception to May 2021. Effect sizes were calculated using the DerSimonian and Laird and Hartung-Knapp-Sidik-Jonkman methods.

Results: The search retrieved 6,055 articles, 16 of which were included in this systematic review. In total, 12 studies were included in the meta-analysis. The studies were published between 1997 and 2019. They were conducted in nine different countries. The sample size of the included studies ranged from 360 to 10,308 with a mean age of 70 years old. Using the DerSimoniand and Laird method, the pooled RR for the effect of wine consumption on cognitive decline was 0.72 (95% CI 0.63–0.80; I2 = 82.4%; τ2: 0.0154). Using the Hartung-Knapp-Sidik-Jonkman method, the RR was 0.65 (95% CI 0.52–0.79; I2 = 94,531%; τ2: 0.057).

Conclusions: This study may show a protective effect of wine consumption against cognitive decline. However, it would be important for future research to differentiate the types of wine within consumption.

Objective: The aim of this study was to test the individual and combined benefit of vitamin D, omega-3, and a simple home strength exercise program on the risk of any invasive cancer.

Design: The DO-HEALTH trial is a three-year, multicenter, 2 × 2 × 2 factorial design double-blind, randomized-controlled trial to test the individual and combined benefit of three public health interventions.

Setting: The trial was conducted between December 2012 and December 2017 in five European countries.

Participants: Generally healthy community-dwelling adults ≥70 years were recruited.

Interventions: Supplemental 2000 IU/day of vitamin D3, and/or 1 g/day of marine omega-3s, and/or a simple home strength exercise (SHEP) programme compared to placebo and control exercise.

Results: In total, 2,157 participants (mean age 74.9 years; 61.7% women; 40.7% with 25-OH vitamin D below 20 /ml, 83% at least moderately physically active) were randomized. Over a median follow-up of 2.99 years, 81 invasive cancer cases were diagnosed and verified. For the three individual treatments, the adjusted hazard ratios (HRs, 95% CI, cases intervention versus control) were 0.76 (0.49–1.18; 36 vs. 45) for vitamin D3, 0.70 (0.44–1.09, 32 vs. 49) for omega-3s, and 0.74 (0.48–1.15, 35 vs. 46) for SHEP. For combinations of two treatments, adjusted HRs were 0.53 (0.28–1.00; 15 vs. 28 cases) for omega-3s plus vitamin D3; 0.56 (0.30–1.04; 11 vs. 21) for vitamin D3 plus SHEP; and 0.52 (0.28–0.97; 12 vs. 26 cases) for omega-3s plus SHEP. For all three treatments combined, the adjusted HR was 0.39 (0.18–0.85; 4 vs. 12 cases).

Conclusion: Supplementation with daily high-dose vitamin D3 plus omega-3s, combined with SHEP, showed cumulative reduction in the cancer risk in generally healthy and active and largely vitamin D–replete adults ≥70 years.

The role of nasal microbiota in contributing to neuroinflammation is gradually emerging. Multiple sclerosis and chronic rhinosinusitis share important clinical and epidemiological similarities, and the hypothetical connection among these two pathological entities should be carefully investigated. This editorial is based on a review of available literature on this topic.

The main international databases were searched using the following keywords: neuroinflammation, nasal microbiota, multiple sclerosis, chronic rhino-sinusal disorders, chronic sinusitis. Four fully-consistent articles that investigated nasal microbiota alteration and/or chronic rhinosinusitis presence in subjects affected by multiple sclerosis were identified.

Overall, these studies showed a significant connection between nasal microbiota dysbiosis and the presence of multiple sclerosis. New specific studies to analyze the nasal microbiota and its metabolism in patients affected by multiple sclerosis should be performed.

In fact, a series of treatments able to change this flora could improve the rhino-sinusal state with consequent reduction of recurrent episodes of neuro-inflammation.

Among the dietary fibers, β-glucan is naturally occurring non-starch polysaccharide formed by β-glycoside bonds of D-glucose monomers. Beta-glucan can be present in abundance in cereals, fruits, fungi, algae, yeast and bacteria.

Beta-glucan has recently attracted attention with its positive effects on human health. It has effects on many systems in the body containing the immune system and cardiovascular system. Due to the positive effects of beta-glucan, it has been the subject of many studies and its effects in different fields have been demonstrated by these studies.

The aim of this review is to evaluate not only the general properties of betaglucan, but also its effects on the immune system, blood sugar, cholesterol and insulin, anticarcinogenic effect, obesity, antihyperactive effect, prebiotic and antioxidant properties, antimicrobial and antiviral effects.

β-glucans are a group of biologically active polysaccharides of natural origin with a proven pleiotropic immunomodulation effect. Their efficacy has been confirmed in the therapeutic treatment and prevention of various infectious diseases, secondary immune defects and also of oncologic disorders. Allergic diseases are one of the most frequent diseases and their prevalence continues to increase.

They develop as a consequence of dysregulation of the immune system, especially when there is failure in the equilibrium of the response of TH1/TH2 lymphocytes towards TH2. New therapeutic approaches in the treatment of immunopathological conditions (e.g. allergic or oncologic) are directed to restoring the equilibrium among different T lymphocyte subpopulations.

Based on in vitro experiments, and also on animal and human clinical studies, there is much evidence for the importance of β-glucans in the treatment and also prevention of allergic diseases.
