Background: Sesamum indicum L. (sesame) is one of the most widely used herbs in the world. Sesame oil contains lignans such as sesamin and sesamolin, which are known to possess anti-inflammatory, antioxidant, and anti-apoptotic properties. Parkinson's disease (PD) is recognized as the most common neurodegenerative disease after Alzheimer's disease; however, the exact molecular mechanism of the progression of neural death is not clear yet. In this study, the effect of sesame seed extracts and their main bioactive components (sesamin and sesamolin) on in vitro model of Parkinson's disease has been compared.

Methods: Cell viability, the number of reactive oxygen species (ROS), and apoptosis were determined using resazurin assay, ROS assay, propidium iodide (PI) staining and flow cytometry, and western blot analysis.

Results: 6-OHDA caused cellular death and apoptosis but pretreatment with sesame seed extracts, sesamin, and sesamolin significantly increased cell viability (p<0.001) and decreased ROS (p<0.001) and apoptosis. ERK1/2 is activated by 6-OHDA in PC12 cells, and the level of survivin decreased. Pretreatment with sesame significantly reversed the entire cell death induced by 6- OHDA. Sesame seed extracts at 5 and 10 μg/ml, sesamin and sesamolin at 5 and 10 μM increased surviving (p<0.01), and reduced P-ERK1/2/ERK1/2 (p<0.05) levels close to the control values.

Conclusions: Overall, compounds in sesame seed extract and sesamin may assist as adjuvant therapeutics in PD. It seems sesame seeds have more potent protection effects against neural death compared with individual components, which might reflect the synergism among different phytochemicals present in the extract.

Background: According to the Persian Medicine (PM) point of view, the function of the cardiovascular system and the risk of cardiovascular events would be different between subjects having warm and cold temperaments. Moreover, different foods in terms of temperament may lead to different acute and chronic effects on the body.

Objective: We investigated the postprandial effects of PM-based warm and cold test meals on arterial stiffness indices in healthy men with warm and cold temperaments.

Methods: Twenty-one eligible warm or cold temperament subjects with a similar range of age, weight, and heights were enrolled in this pilot cross-over randomized controlled trial study during February- October 2020. Two test meals (cold and warm PM-based temperament foods) were designed as different interventions. Pulse wave velocity (PWV) and pulse wave analysis (PWA) was obtained at the baseline state (following 12 hours fasting), 0.5, 2, and 4 hours after the test meal consumption during each test day.

Results: Warm temperament participants had higher values of lean body mass, total body water, and protein content (P = 0.03, 0.02, and 0.02, respectively). Cold temperament individuals had higher aortic heart rate (HR) following 12 hours of fasting (P <0.001). On the other hand, the augmentation pressure (AP) of warm temperament individuals was higher than the colds ( P = < 0.001).

Conclusion: According to the results of the present study, although warm temperament individuals could have higher arterial stiffness at the fasting state, arterial stiffness indices had a greater reduction following warm-temperament meal intake compared to cold-temperament meal.

In recent times, bioplastics have become an integrated sustainable alternative to plastic management to lessen the dependency on fossil fuels as well as better plastic disposal methods. Through this study, the focus is laid upon the dire need for developing bio-plastics for transforming to a sustainable future as bio-plastics are renewable, more feasible, and a sustainable option when compared to the high-energy consuming conventional oil-based plastics. Bioplastics might not be a one-stop solution for all environmental issues caused by plastics, but it will be a beneficial step for expanding biodegradable polymer as society's current concerns about the environment makes this an ideal time for further growth of biopolymers. Moreover, the potential market for agricultural materials in bioplastics is leading to an economic push toward the growth of the bioplastic industry, thus providing better alternatives for a future sustainable environment. The objective of the review is to provide detailed knowledge about plastics obtained from various renewable sources, their production, life cycle, market share, applications, and roles to act as a sustainable source of synthetic plastics, thereby featuring various possibilities and potentialities of bioplastics to perform as an alternative solution for waste reduction.

Background: One of the significant problems with peanut butter is oil separation when the product is opened after some time. The selection of vegetable oil, which acts as a stabiliser, plays a significant role in nut butter's textural and sensory quality.

Objective: This study aimed to optimise the formulation of cashew nut butter using response surface methodology (RSM). Four different vegetable oils, namely olive oil, virgin coconut oil, soybean oil and palm oil, were used to select efficient vegetable oil based on its effect on the physicochemical characteristics and sensory evaluation of cashew nut butter.

Methods: Thirteen formulations of cashew nut butter from RSM were produced to determine the optimum amount of selected oil (olive oil) and honey.

Results: Cashew nut butter stabilised with olive oil showed the best and similar values to commercial peanut butter with the lowest oil separation 3.91% and lower values of texture data of firmness (85.8 g), shear work (87.8 g.sec), stickiness (-27.44 g) and work of adhesion (-36.07 g.sec). The recommended volumes of olive oil and honey for cashew nut butter production were 1.29% and 6.16%, respectively. Consumers favor cashew nut butter, according to sensory analysis' overall acceptance. In terms of nutritional quality, cashew nut butter contains a high amount of fat (47.25%), followed by carbohydrates (24.51%) and protein (16.4%).

Conclusion: The type of oil showed significant effects on the stability and spreadability of the produced cashew nut butter.

Humans and many other creatures depend on agriculture for survival, but it is impossible to cultivate without the use of pesticides. Different types of harmful organism or pest exists in every agricultural crop. Synthetic pesticides are widely utilised around the world as a solution to this problem, but there are drawbacks associated with their application, the most significant of which are the severe negative impacts on ecosystems and human health. Organically made pesticides should be used instead of synthetic pesticides to reduce their harmful effects. Unlike chemical pesticides, natural pesticides do not cause any harm to non-target creatures and are inexpensive. Most botanical pesticides degrade rapidly, usually in only a few days but sometimes may even take hour. One of the most promising approaches to reducing pesticide pollution and protecting crops, food, and the environment is to use botanical insecticides. Beneficial insects such as earthworms are much less likely to be killed by biopesticides. The source of herbal insecticides is herbal plants. Each plant has distinct effect since every plant have their own chemical constituent. This review explains about numerous herbs and shrubs that feature distinct insecticidal, pesticidal and repelling effect. Insecticidal activity is discovered in a broad variety of herbal plants, and this review analyses those plants in detail, defining the major active ingredient responsible for these effects.

Background: Hydroxychloroquine (HCQ) is a common antimalarial drug that has been used effectively in the treatment of various rheumatic and auto-immunity diseases. The major side effects and drawbacks associated with HCQ are cardiotoxicity, retinopathy, gastrointestinal upset, and neuromyopathy however, cardiotoxicity is an increasing concern and it is critical to avoid heart dysfunction induced by HCQ. The present work is focused on receptor and signaling molecules associated with pathways attributing to drug-induced cardiotoxicity. We analyzed the therapeutic efficacy of selected natural products in HCQ-induced cardiotoxicity through insilico. We selected Syzygium cumini polyphenols, quercetin, and p-coumaric acid. The motivation behind selecting quercetin, and p-coumaric acid is their wide applicability as an antioxidative, anti-inflammatory, antiapoptotic, and cardioprotective.

Methods: For predicting quercetin, p-coumaric acid, and HCQ toxicity and physicochemical properties, in silico studies were performed using ProTox II and Swiss ADME. We further performed molecular docking using Autodock Vina and Discovery Studio visualizer to find the affinity of selected polyphenols against signaling molecules and receptors. Then we performed network pharmacological studies of selected signaling molecules.

Results: We analyzed that the computational method indicated quercetin (Δ G -9.3 kcal/mol) has greater binding affinity than p-Coumaric acid for prevention and restoration of the disease while hydroxychloroquine was taken as a control.

Conclusion: It can be concluded that Syzygium cumini, polyphenols may aid in the future therapeutic potential against HCQ-induced cardiotoxicity.

Background: Essential oils that are extracted from plants have shown beneficial effects on humans and animals, evidenced by traditional medicine. They possess many essential phytocomponents that act as antimicrobial agents, and most of them are safe for external usage.

Introduction: Lemongrass essential oil is extracted from the grass, such as Cymbopogon flexuosus, and is used for antimicrobial activity for a long time. The efficacy of this oil is limited due to the poor solubility and microbial penetration, easy vaporization, and lower stability. Nanoformulations and nanoencapsulations are nanotechnology fields that aim to improve the bioavailability of many natural compounds and enhance their stability. Lemongrass oil has also been nanoformulated as nanoemulsion, and various antimicrobial activities against various pathogens have been demonstrated, which are superior to free lemongrass oil.

Methodology: We have used the search engines PubMed and Google Scholar for the mentioned keywords and selected the recent references related to this topic.

Conclusion: In this review, we have discussed various antimicrobial properties of lemongrass essential oil nanoemulsion and its application, such as antibacterial, antifungal, pesticidal, food preservative, and antibiofilm activity.

Background: The balanced composition of the gut microbiota is essential for human health. The dysbiotic condition may develop various complex diseases. A metabolic syndrome is a group of biochemical and physiological abnormalities that can increase the risk of cardiovascular diseases, diabetes, and inflammatory diseases. It has become a serious concern worldwide because there is no acceptable medication to overcome this problem.

Objective: This review aims to evaluate the relationship between gut microbiota and metabolic syndrome. The balance of gut microbiota relates to human health as well as diseases. Patents related to significant findings on probiotics, prebiotics, synbiotics, and fecal microbiota transplantation signify the importance of the proposed theme and provide promising therapeutic strategies to modulate the dysbiotic condition and reoccurrence of beneficial microbial species during metabolic syndromes. Screening of patents-related databases can be worth full to track new technology. Therefore, some selected recent patents related to gut microbiota and associated therapies have been discussed in the present manuscript.

Conclusion: Under the existing situation, the role of gastrointestinal microbiota as a therapeutic agent is becoming more utilized for treating human health issues and various metabolic syndromes including obesity, diabetes, and cardiovascular diseases. Understanding gut dysbiosis and associated complex interactions between microbes and hosts would be effective for designing future therapeutic interventions for metabolic syndrome. Our detailed patent analysis reflects that gut dysbiosis has a prominent role in metabolic syndromes and dietary therapeutic strategies can improve health by modulating the human microbiota, their metabolites ad stability.

Background: The glycation of proteins and lipids synthesizes the advanced glycation end products (AGEs), i.e., substances that irreversibly damage macromolecules present in tissues and organs, which contribute to the impairment of biological functions. For instance, the accumulation of AGEs induces oxidative stress, the inflammatory responses, and consequently the on set/worsening of diseases, including obesity, asthma, cognitive impairment, and cancer. There is a current demand on natural and low-cost sources of anti-AGE agents. As a result, food phytochemicals presented promising results to inhibit glycation and consequently, the formation of AGEs.

Objective: Here we describe how the AGEs are present in food via Maillard reaction and in organs via natural aging, as well as the effects of AGEs on the worsening of diseases. Also we described the methods used to detect AGEs in samples, and the current findings on the use of phytochemicals (phenolic compounds, phytosterols, carotenoids, terpenes and vitamins) as natural therapeuticals to inhibit health damages via inhibition of AGEs in vitro and in vivo.

Methods: This manuscript reviewed publications available in the PubMed and Science Direct databases dated from the last 20 years on the uses of phytochemicals for the inhibition of AGEs. Recent patents on the use of anti-AGEs drugs were reviewed with the use of Google Advanced Patents database.

Results and discussion: There is no consensus about which concentration of AGEs in blood serum should not be hazardous to the health of individuals. Food phytochemicals derived from agroindustry wastes, including peanut skins, and the bagasses derived from citrus and grapes are promising anti-AGEs agents via scavenging of free radicals, metal ions, the suppression of metabolic pathways that induces inflammation, the activation of pathways that promote antioxidant defense, and the blocking of AGE connection with the receptor for advanced glycation endproducts (RAGE).

Conclusion: Phytochemicals derived from agroindustry are promising anti-AGEs, which can be included to replace synthetic drugs to inhibit AGE formation, and consequently to act as therapeutical strategy to prevent and treat diseases caused by AGEs, including diabetes, ovarian cancer, osteoporosis, and Alzheimer's disease.
