An integrative approach for management of post-traumatic dorsal foot wounds - A case report.

Crush injuries to the foot have become increasingly prevalent in contemporary settings, primarily arising from incidents such as the impact of large objects falling onto the foot or involvement in traffic accidents. The complexity of treating these injuries is compounded by the intricate anatomy of the foot. In specific scenarios, the implementation of an integrated management approach could prove advantageous. In this report, we depict the case of a 23-year-old male who visited the Shalya OPD with a wound on his left foot caused by trauma. The wound covered the medial portion of the foot, involving the dorsal area, and measured roughly 20 cm by 9 cm and was unable to walk. We successfully managed the case by adopting an integrative approach. The Ayurvedic treatment included Panchavalkala kashaya for wound irrigation, as well as oral administration of Amalaki rasayana, Triphala guggulu, Shatavari churna and Ashwagandha churna. Jatyadi taila was topically applied. For the first seven days, in addition to these ayurvedic medications, we also employed analgesics and antibiotics to treat infection and pain. To accomplish early closure, we employed a split-thickness skin graft after sufficient granulation tissue had appeared. The wound was completely healed within three months and the patient was able to walk freely without any support. The combined approach yielded a promising result in this case.

Physiological and biochemical regulation of Valeriana jatamansi Jones under water stress.

Understanding the physiological and biochemical regulations in a medicinal plant under stress environments is essential. Here, the effect of water stress such as flooding and water deficit [80% (control), 60%, 40%, 20% field capacity (FC)] conditions on Valeriana jatamansi was studied. Both types of water stresses retarded the plant growth and biomass. Photosynthetic pigments were reduced with maximum reduction under flood stress. Chlorophyll fluorescence study revealed distinct attributes under applied stresses. Better performance index (PI) of flood-grown plants (than 20% and 40% FC) and higher relative fluorescence decrease ratio (Rfd) in 40% FC and flood-grown plants than that of control plants, indicated the adaptation ability of plants under water deficit (40% FC) and flood stress. Reduction in net photosynthetic rate was lesser in flood stress (40.92%) compared to drought stress (73.92% at 20% FC). Accumulation of starch was also decreased (61.1% at 20% FC) under drought stress, while it was increased (24.59%) in flood stress. The effect of water stress was also evident with modulation in H2O2 content and membrane damage. Differential modulation of biosynthesis of secondary metabolites (valtrate, acevaltrate and hydroxyl valerenic acid) and expression of iridoid biosynthetic genes under water stress was also revealed. The present study demonstrated the distinct effect of drought and flood stress on V. jatamansi plants, and drought [20% FC] caused severe loss and more damage than flood stress. Therefore, severe drought should be avoided during cultivation of V. jatamansi and regulated water stress-applications have potential for modulation of biosynthesis of specific secondary metabolites.

Uncovering the genomic regions underlying grain iron and zinc content using genome-wide association mapping in finger millet.

Finger millet, being rich source of essential minerals like iron and zinc, is an ideal model to identify candidate genes contributing to high grain iron content (GIC) and zinc content (GZC) in plants. Hence, finger millet diversity panel comprised of 202 genotypes was evaluated in two geographical locations and found to have a wide variation for GIC and GZC. A genome-wide association study using 2977 single nucleotide polymorphism (SNP) markers identified reliable marker-trait associations (MTAs). The use of general linear model (GLM) and mixed linear model (MLM) approaches revealed 5 and 8 common MTAs linked to GIC and GZC, respectively, for both Almora and Pantnagar locations, with a high level of significance (P < 0.01). However, 12 significant MTAs were found to be linked with GIC for Pantnagar location alone. The MTAs were associated with specific genes that produce ferritin (Fer1), iron-regulated transporter-like protein (IRT2), and yellow stripe-like 2 proteins (YSL2). These genes are likely linked to GIC variation in finger millet. Additionally, the variation in GZC in finger millet was connected to genes that encode zinc transporters, namely ZIP1 protein (ZIP1) and ZTP29-like protein (ZTP29). Compared to low GIC and GZC genotypes, high GIC and GZC genotypes exhibited greater relative expression of these genes.

Xanthan gum coatings augmented with lemongrass oil preserve postharvest quality and antioxidant defence system of Kinnow fruit under low-temperature storage.

Kinnow mandarin is an important citrus fruit that undergoes various postharvest qualitative losses. Therefore, the present study aimed to investigate the effect of polysaccharide-based xanthan gum (XG) coatings and lemongrass essential oil (LG) on the nutritive quality of Kinnow mandarins stored at 5-7 °C, 90-95 % RH for 75 days. The results revealed that in comparison to control the coatings maintained the fruit titratable acidity (TA), soluble solid content (SSC), ascorbic acid (AsA) content, total flavonoid content (TFC), and juice content, along with reduced weight loss and spoilage incidence. The coated fruits also exhibited higher sensory quality, total antioxidant activity (TAA), and activities of enzymes; catalase (CAT), peroxidase (POD), and phenylalanine ammonia-lyase (PAL). At the end of storage, the fruits coated with XG 1.0 % + LG 1.0 % exhibited maximum TA (0.69 %), AsA content (203.5 mg L-1), and TFC (0.21 mg g-1) with minimum weight loss (7.57 %) and spoilage (3.01 %) and SSC (11.87 %). The scanning electron microscopic (SEM) images of the coated fruits also exhibited smooth surfaces with closed stomata pores. Overall, XG 1.0 % + LG 1.0 % proved as a potential postharvest treatment for maintaining the nutritive quality of Kinnow under low-temperature storage.

Adhatoda vasica and Tinospora cordifolia extracts ameliorate clinical and molecular markers in mild COVID-19 patients: a randomized open-label three-armed study.

BACKGROUND: SARS-CoV-2 infections caused mild-to-moderate illness. However, a sizable portion of infected people experience a rapid progression of hyper-inflammatory and hypoxic respiratory illness that necessitates an effective and safer remedy to combat COVID-19. METHODS: A total of 150 COVID-19-positive patients with no to mild symptoms, between the age groups 19-65 years were enrolled in this randomized, open-labeled three-armed clinical trial. Among them, 136 patients completed the study with RT-PCR negative reports. The patients received herbal drugs orally (Group A (Adhatoda vasica; AV; 500 mg; n = 50); Group B (Tinospora cordifolia; TC; 500 mg; n = 43), and Group C (AV + TC; 250 mg each; n = 43)) for 14 days. Clinical symptoms, vital parameters, and viral clearance were taken as primary outcomes, and biochemical, hematological parameters, cytokines, and biomarkers were evaluated at three time points as secondary outcomes. RESULTS: We found that the mean viral clearance time was 13.92 days (95% confidence interval [CI] 12.85-14.99) in Group A, 13.44 days (95% confidence interval [CI] 12.14-14.74) in Group B, and 11.86 days (95% confidence interval [CI] 10.62-13.11) days in Group C. Over a period of 14 days, the mean temperature in Groups A, and B significantly decreased linearly. In Group A, during the trial period, eosinophils, and PT/INR increased significantly, while monocytes, SGOT, globulin, serum ferritin, and HIF-1α, a marker of hypoxia reduced significantly. On the other hand, in Group B hsCRP decreased at mid-treatment. Eosinophil levels increased in Group C during the treatment, while MCP-3 levels were significantly reduced. CONCLUSIONS: All the patients of the three-armed interventions recovered from COVID-19 and none of them reported any adverse effects from the drugs. Group C patients (AV + TC) resulted in a quicker viral clearance as compared to the other two groups. We provide the first clinical report of AV herbal extract acting as a modifier of HIF-1α in COVID-19 patients along with a reduction in levels of ferritin, VEGF, and PT/INR as the markers of hypoxia, inflammation, and thrombosis highlighting the potential use in progression stages, whereas the TC group showed immunomodulatory effects.

The relationship between BCG immunotherapy and oxidative stress parameters in patients with nonmuscle invasive bladder cancer.

INTRODUCTION: Environmental chemicals have been associated with the regulation of oxidative stress markers, which have the potential for the development of bladder cancer. However, limited studies on the function of oxidative stress parameters and nonmuscle invasive bladder cancer (NMIBC) in therapy response are available. Here we studied the oxidative stress parameters in response to BCG immunotherapy in NMIBC patients. MATERIAL AND METHODS: A total of 120 patients with NMIBC and treatment with BCG were enrolled and categorized into 2 groups on BCG response, 50 patients were BCG-responsive (BCG-R) and 70 were BCG-nonresponsive (BCG-N). BCG-R have no evidence of tumor recurrence or advancement after 1 year of BCG immunotherapy, but BCG-N has a recurrence of tumor after 3 to 6 months cycles of BCG instillation, as determined by cystoscopy. In all groups, we measured the levels of oxidative stress markers- malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD), and catalase (CAT). RESULTS: The levels of oxidative stress markers viz. MDA, NO, and SOD in the BCG-N group were significantly higher (P < 0.001) than in the BCG-R group. Furthermore, the data demonstrated a significant correlation between oxidative stress marker and NMIBC T1 high grade and tumor size >2.5 cm. However, no statistically significant difference was found between studied groups with CAT. CONCLUSION: The findings suggest that the carcinogenesis of NMIBC is associated with oxidative damage of biomolecules and indicates the involvement of oxidative stress markers in the development and recurrence of NMIBC.; Therefore, it is critical to ensure the management for T1 high grade and tumor size of >2.5 cm for antioxidant protection.

Effect of supplementation of fennel seed powder on intake, growth performance, gut health and economics in goats.

The aim of this study was to evaluate the effect of fennel seed powder (FSP) at varying levels on intake, growth, gut health, body condition, body measurements and economics in post weaned male goats. For this experiment a total of 30 post weaned male kids of Barbari goats with statistically similar body weight (P = 0.575) and age (3-4 months) were randomly distributed in three comparable groups each having 10 kids. Three groups viz. control (no supplementation), T1 (0.5% of DM in diet) and T2 (1.0% of DM in diet) were formed and the study continued up to 5 months. Statistical analysis of results showed significant effect of FSP supplementation on intake, growth, body condition, and gut health and body measurements in goats of treatment groups. Significantly highest body weight (BW), average daily gain (ADG) and dry matter intake (DMI) (P < 0.001) was reported in T2 group, followed by T1 than control group goats. Further, feed conversion ratio (FCR), feed conversion efficiency (FCE%) and body condition score of treatment groups (T1 and T2) was improved significantly (P < 0.001) than control group goats. However, FCR and FCE% in T1 and T2 differed non- significantly (P > 0.05). Analysis of fecal samples indicated significantly higher (P < 0.001) fecal dry matter (FDM%), fecal consistency score (FS) in T1 and T2 group than control group whereas parasitic fecal egg count per gram (EPG) was significantly lower in T1 and T2 group than control group. However, EPG in T1 and T2 differed non- significantly (P > 0.05). Body measures differed significantly (P < 0.05) among groups. Economic evaluation of FSP supplemented showed that T1 and T2 group fetched INR 462 and 501 per goat on selling over control group (1USD = 82.54 INR). It can be concluded from this study that supplementation of FSP @ 1.0% of DM in diet may economically improve intake, growth, gut health, body condition, body measurements and economics in post weaned male Barbari goats.

Computational evaluation of phytochemicals targeting DNA topoisomerase I in Leishmania donovani: molecular docking and molecular dynamics simulation studies.

DNA topoisomerase I (Topo I) is a ubiquitous enzyme that plays a crucial role in resolving the topological constraints of supercoiled DNA during various cellular activities, including repair, replication, recombination, transcription, and chromatin remodeling. Multiple studies have confirmed the essential role of Topo I in nucleic acid metabolism of Leishmania donovani, the kinetoplastid parasite responsible for visceral leishmaniasis or kala-azar. Inhibition of this enzyme has shown promise as a strategy for therapy against visceral leishmaniasis. However, current treatment options suffer from limitations related to effectiveness, cost, and side effects. To address these challenges, computational methods have been employed in this study to investigate the inhibition of Leishmania donovani DNA topoisomerase I (LdTopo I) by phytochemicals derived from Indian medicinal plants known for their anti-leishmanial activity. A library of phytochemicals and known inhibitors was assembled, and virtual screening based on docking binding affinities was conducted to identify potent phytochemical inhibitors. To assess the drug-likeness of the docked phytochemicals, their physicochemical properties were predicted. Additionally, molecular dynamics (MD) simulations were performed on the docked complexes for a duration of 100 ns to evaluate their stability, intermolecular interactions, and dynamic behavior. Among all the docked phytochemicals, three compounds, namely CID23266147 (withanolide N), CID5488537 (fagopyrine), and CID100947536 (isozeylanone), exhibited the highest inhibitory potential against LdTopo I. These findings hold promise for the development of novel inhibitors targeting LdTopo I, which could potentially lead to improved therapies for visceral leishmaniasis.Communicated by Ramaswamy H.

Bidirectional Effect of Triphala on Modulating Gut-Brain Axis to Improve Cognition in the Murine Model of Alzheimer's Disease.

SCOPE: The emerging role of gut microbiota and their metabolites in the modulation of the gut-brain axis has received much attention as a new hope for the treatment of hard-to-treat chronic neurodegenerative diseases like Alzheimer's disease. The naturally occurring polyphenols can restore the gut-brain axis by modulating gut microbiota and brain neurotransmitters. The Indian traditional medicine Triphala, a rich source of polyphenols, has been used on humans based on Prakriti or disease conditions for many years. METHODS AND RESULTS: In this study, the dual mode (morning and evening) action of Triphala is used to provide scientific evidence of its superior preventive and therapeutic efficacy in C57BL/6 and 5xFAD, APP/PS1 transgenic mouse model of Alzheimer's disease. The study observes that Triphala treatment has significantly improved cognitive function, by modulating the APP pathway, reducing inflammation, and restoring the gut-brain axis by increasing the gut microbiota phyla of Bacteroides, Proteobacteria, Actinobacteria, etc., involved in maintaining the gut homeostasis. CONCLUSIONS: The study paves a new path for using dual modes of Triphala alone or in combination to treat incurable AD.

Opium alkaloids, biosynthesis, pharmacology and association with cancer occurrence.

Papaver somniferum L. (Family: Papaveraceae) is a species well known for its diverse alkaloids (100 different benzylisoquinoline alkaloids (BIAs)). L-tyrosine serves as a precursor of several specific metabolites like BIAs. It has been used as an antitussive and potent analgesic to alleviate mild to extreme pain since ancient times. The extraction of pharmaceutically important alkaloids like morphine and codeine from poppy plant reflects the need for the most suitable and standard methods. Several analytical and extraction techniques have been reported in open literature for morphine, codeine and other important alkaloids which play a vital function in drug development and drug discovery. Many studies suggest that opioids are also responsible for adverse effects or secondary complications like dependence and withdrawal. In recent years, opium consumption and addiction are the most important risk factors. Many evidence-based reviews suggest that opium consumption is directly linked or acts as a risk factor for different cancers. In this review, we highlight significant efforts related to research which have been done over the past 5 decades and the complete information on Papaver somniferum including its phytochemistry, pharmacological actions, biosynthetic pathways and analytical techniques of opium alkaloid extraction and the link between opium consumption and cancer-related updates.

Comparative Genomics and Physiological Investigations Supported Multifaceted Plant Growth-Promoting Activities in Two Hypericum perforatum L.-Associated Plant Growth-Promoting Rhizobacteria for Microbe-Assisted Cultivation.

Plants are no longer considered standalone entities; instead, they harbor a diverse community of plant growth-promoting rhizobacteria (PGPR) that aid them in nutrient acquisition and can also deliver resilience. Host plants recognize PGPR in a strain-specific manner; therefore, introducing untargeted PGPR might produce unsatisfactory crop yields. Consequently, to develop a microbe-assisted Hypericum perforatum L. cultivation technique, 31 rhizobacteria were isolated from the plant's high-altitude Indian western Himalayan natural habitat and in vitro characterized for multiple plant growth-promoting attributes. Among 31 rhizobacterial isolates, 26 produced 0.59 to 85.29 µg mL-1 indole-3-acetic acid and solubilized 15.77 to 71.43 µg mL-1 inorganic phosphate; 21 produced 63.12 to 99.92% siderophore units, and 15 exhibited 103.60 to 1,296.42 nmol α-ketobutyrate mg-1 protein h-1 1-aminocyclopropane-1-carboxylate deaminase (ACCD) activity. Based on superior plant growth-promoting attributes, eight statistically significant multifarious PGPR were further evaluated for an in planta plant growth-promotion assay under poly greenhouse conditions. Plants treated with Kosakonia cowanii HypNH10 and Rahnella variigena HypNH18 showed, by significant amounts, the highest photosynthetic pigments and performance, eventually leading to the highest biomass accumulation. Comparative genome analysis and comprehensive genome mining unraveled their unique genetic features, such as adaptation to the host plant's immune system and specialized metabolites. Moreover, the strains harbor several functional genes regulating direct and indirect plant growth-promotion mechanisms through nutrient acquisition, phytohormone production, and stress alleviation. In essence, the current study endorsed strains HypNH10 and HypNH18 as cogent candidates for microbe-assisted H. perforatum cultivation by highlighting their exclusive genomic signatures, which suggest their unison, compatibility, and multifaceted beneficial interactions with their host and support the excellent plant growth-promotion performance observed in the greenhouse trial. IMPORTANCE Hypericum perforatum L. (St. John's wort) herbal preparations are among the top-selling products to treat depression worldwide. A significant portion of the overall Hypericum supply is sourced through wild collection, prompting a rapid decline in their natural stands. Crop cultivation seems lucrative, although cultivable land and its existing rhizomicrobiome are well suited for traditional crops, and its sudden introduction can create soil microbiome dysbiosis. Also, the conventional plant domestication procedures with increased reliance on agrochemicals can reduce the diversity of the associated rhizomicrobiome and plants' ability to interact with plant growth-promoting microorganisms, leading to unsatisfactory crop production alongside harmful environmental effects. Cultivating H. perforatum with crop-associated beneficial rhizobacteria can reconcile such concerns. Based on a combinatorial in vitro, in vivo plant growth-promotion assay and in silico prediction of plant growth-promoting traits, here we recommend two H. perforatum-associated PGPR, Kosakonia cowanii HypNH10 and Rahnella variigena HypNH18, to extrapolate as functional bioinoculants for H. perforatum sustainable cultivation.

"Ayurveda management of Palmoplantar Psoriasis (Vipadika) -a case report".

INTRODUCTION: Palmo-plantar Psoriasis is a non-infectious chronic inflammatory disease of the skin bounded to the palm and soles in extent. In Ayurveda, all skin diseases are recounted under a single rubric i.e., Kushtha (skin diseases); PPP (Palmo-plantar Psoriasis) may be correspondent with Vipadika (one of the Kshudra Kushtha described in Ayurveda), based on its clinical sign & symptom. OBJECTIVES: The role of Ayurvedic regimen in Palmo plantar psoriasis. METHODOLOGY: Here we are presenting a case of 68-year-old man with a long 8-year history of pruritic rashes on his both palms and soles which was diagnosed as Palmo-Plantar Psoriasis (Vipadika) and successfully managed with simple Ayurveda medicines, external application of Jivantyadi Yamaka, external washing with Triphala decoction and 3 sitting of Jalaukavacharana (Leech Application). RESULT: The patient reported a significant improvement in the complaints of itch and rash, on the scale and erythema of the palms and soles in a span of about 3 weeks. CONCLUSION: We, therefore, recommend the treatment of Palmo -plantar Psoriasis starting with leech application along with oral and external Ayurveda medication, and results can be seen.

An update on possible alternative therapeutics for future periodontal disease management.

Periodontitis is an inflammatory disease caused by microbial infections of the gum. At an advanced stage, periodontitis can even destroy the alveolar bone. Fusobacterium nucleatum, Prevotella intermedia, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Capnocytophaga gingivalis, and Pr. nigrescens are the major pathogens in periodontitis. Scaling and root planning are used together with local or systemic antibiotics to treat periodontitis. The difficulty in complete eradication of periodontal pathogens frequently leads to the relapse of the disease. As not many new antibiotics are available in the market, many researchers are now focusing on developing alternative strategies against periodontal microbes. This review provides an overview of the possible use of bacteriophages, lysins, honey, plant extracts, metallic salts, nanoparticles, and vaccines as alternative therapeutic agents against periodontal infections. The information provided here could help in designing alternative therapeutics for the treatment of periodontal infections.

Complex Anal fistula treated with IFTAK (Interception of fistulous track with application of ksharsutra) technique- A case report.

BACKGROUND: An anal fistula is a common benign anorectal disease that tends to reoccur simple or low-type fistulas can be treated without affecting the sphincter mechanism; however, repairing a complex ano fistula without compromising anal continence can be difficult for a surgeon. CASE PRESENTATION: Here, we present an anal fistula of complex clinical appearance managed successfully by the IFTAK (Interception of fistulous track with application of ksharsutra) technique practiced at Banaras Hindu University, Varanasi, India. The diagnosis was made via visual and bi-manual digital rectal examination then confirmed by Endoanal ultrasonography (EAUS). The patient showed remarkable improvement and the fistula healed completely in due course of time without impairing the anal continence status of the patient. At four months of follow-up the patient was healthy and no recurrence was found. CONCLUSION: IFTAK is a minimally invasive technique and very effective in managing complex fistula in ano of cryptoglandular origin. The main cause of recurrence in complex anal fistula is non-identification of an infected anal crypt, secondary extensions, associated sepsis, or abscess at the time of examination or surgery. So, precise diagnosis and appropriate surgical measures play an equal role in the successful outcome of anal fistula treatment, failure to either will result in non-healing or recurrence.

Challenges in Accessing and Delivering Maternal and Child Health Services during the COVID-19 Pandemic: A Cross-Sectional Rapid Survey from Six States of India.

BACKGROUND/OBJECTIVES: Globally, the COVID-19 pandemic and its prevention and control policies have impacted maternal and child health (MCH) services. This study documents the challenges faced by patients in accessing MCH services, and the experiences of health care providers in delivering those services during the COVID-19 outbreak, explicitly focusing on the lockdown period in India. METHODS: A cross-sectional study (rapid survey) was conducted in 18 districts from 6 states of India during March to June, 2020. The sample size included 540 MCH patients, 18 gynaecologists, 18 paediatricians, 18 district immunisation officers and 108 frontline health workers. Bivariate analysis and multivariable analysis were used to assess the association between sociodemographic characteristics, and challenges faced by the patients. RESULTS: More than one-third of patients (n = 212; 39%) reported that accessing MCH services was a challenge during the lockdown period, with major challenges being transportation-related difficulties (n = 99; 46%) unavailability of hospital-based services (n = 54; 23%) and interrupted outreach health services (n = 39; 18.4%). The supply-side challenges mainly included lack of infrastructural preparedness for outbreak situations, and a shortage of human resources. CONCLUSIONS/RECOMMENDATIONS: A holistic approach is required that focuses on both preparedness and response to the outbreak, as well reassignment and reinforcement of health care professionals to continue catering to and maintaining essential MCH services during the pandemic.

Metaheuristic algorithm integrated neural networks for well-test analyses of petroleum reservoirs.

In recent years, well-test research has witnessed several works to automate reservoir model identification and characterization using computer-assisted models. Since the reservoir model identification is a classification problem, while its characterization is a regression-based task, their simultaneous accomplishment is always challenging. This work combines genetic algorithm optimization and artificial neural networks to identify and characterize homogeneous reservoir systems from well-testing data automatically. A total of eight prediction models, including two classifiers and six regressors, have been trained. The simulated well-test pressure derivatives with varying noise percentages comprise the training samples. The feature selection and hyperparameter tuning have been performed carefully using the genetic algorithm to enhance the prediction accuracy. The models were validated using nine simulated and one real-field test case. The optimized classifier identifies all the reservoir models with a classification accuracy higher than 79%. In addition, the statistical analysis approves that the optimized regressors accurately perform the reservoir characterization with mean relative errors of lower than 4.5%. The minimized manual interference reduces human bias, and the models have significant noise tolerance for practical applications.

AYURAKSHA, a prophylactic Ayurvedic immunity boosting kit reducing positivity percentage of IgG COVID-19 among frontline Indian Delhi police personnel: A non-randomized controlled intervention trial.

Objective: The world continues to face the COVID-19 crisis, and efforts are underway to integrate traditional medicine interventions for its effective management. The study aimed to determine the efficacy of the "AYURAKSHA" kit in terms of post-interventional percentage of COVID-19 IgG positivity, immunity levels, and quality of life (QoL) against COVID-19. Method: This was a non-randomized controlled, prospective intervention trial, done after the distribution of 80,000 AYURAKSHA kits (constituent of Sanshamani Vati, AYUSH Kadha, and Anu Taila) among Delhi police participants in India. Among 47,827 participants, the trial group (n = 101) was evaluated with the positivity percentage of IgG COVID-19 and Immune Status Questionnaire (ISQ) scores as a primary outcome and the WHO Quality of Life Brief Version (QOL BREF) scores along with hematological parameters as a secondary outcome in comparison to the control group (n = 71). Results: The data showed that the percentage of COVID-19 IgG positivity was significantly lower in the trial group (17.5 %) as compared to the control group (39.4 %, p = 0.003), indicating the lower risk (55.6%) of COVID-19 infection in the trial group. The decreased incidence (5.05%) and reduced mortality percentage (0.44%) of COVID-19 among Delhi police officers during peak times of the pandemic also corroborate our findings. The ISQ score and WHO-QOL BREF tool analysis showed the improved scores in the trial group when compared with the controls. Furthermore, no dysregulated blood profile and no increase in inflammation markers like C-reactive protein, erythrocyte sedimentation rate, Interleukin-6 (IL-6) were observed in the trial group. However, significantly enhanced (p = 0.027) IL-6 levels and random blood sugar levels were found in the control group (p = 0.032), compared to a trial group (p = 0.165) post-intervention. Importantly, the control group showed more significant (p = 0.0001) decline in lymphocyte subsets CD3+ (% change = 21.04), CD4+ (% change = 20.34) and CD8+ (% change = 21.54) levels than in trial group, confirming more severity of COVID-19 infection in the control group. Conclusion: The AYURAKSHA kit is associated with reduced COVID-19 positivity and with a better quality of life among the trial group. Hence, the study encourages in-depth research and future integration of traditional medicines for the prevention of the COVID-19 pandemic.

Our focus was to explain the role of the phytoconstituent molecules in invading the cancer pathways to combat the expansion of cells. Furthermore, we still feel that there is a scope for more in silico and in vivo studies to understand and identify the specific site of action in tumoral cells and their mechanistic pathways. In conclusion, Garcinia mangostana can act as an anticancer agent by attacking various molecular pathways.

Development, method validation and simultaneous quantification of eleven bioactive natural products from high-altitude medicinal plant by high-performance liquid chromatography.

Herein, a novel, rapid, reliable, simple method validation and simultaneous quantification of 11 bioactive compounds (mostly xanthones) have been described. International Conference on Harmonization guidelines were used for the analytical method validation. Good linearity, repeatability, intra- and inter-day precision, accuracy and reliability were well-illuminated in the method validation procedure. The calibration curves showed a good linear relationship (r > 0.999) within test range. Precision was evaluated by intra- and inter-day tests with relative standard deviation <2.79% and accuracy validation recovery of 74.16%-91.84%. On quantification study, the validated method described the high content of bioactive xanthone derivatives, including 1-hydroxy-3, 5-dimethoxyxanthone (7), 2-(allyloxy)-8-hydroxy-1, 6-dimethoxyxanthone (6) 1, 7, 8-trihydroxy-3-methoxyxanthone (9) and Coxanthone E (5) in Codonopsis ovata, which is advantageous given the numerous pharmacological and biological effects associated with these compounds, which mostly exhibit anti-cancerous, antioxidant, anti-inflammatory, anti-mutagenic and anti-obesity effects. The bulk abundance of these compounds can also be used for further modification to produce better lead molecules for drug discovery with low toxicity and high potency. The proposed method makes it possible to simultaneously determine all bioactive compounds in one run and can be extended to marker-based standardization of herbal formulations in medicinal and pharmaceutical industries.

Garlic exosome-like nanoparticles reverse high-fat diet induced obesity via the gut/brain axis.

Background: Obesity is becoming a global epidemic and reversing the pathological processes underlying obesity and metabolic co-morbidities is challenging. Obesity induced chronic inflammation including brain inflammation is a hallmark of obesity via the gut-brain axis. The objective of this study was to develop garlic exosome-like nanoparticles (GaELNs) that inhibit systemic as well as brain inflammatory activity and reverse a HFD induced obesity in mice. Methods: GELNs were isolated and administrated orally into HFD fed mice. GaELNs were fluorescent labeled for monitoring their in vivo trafficking route after oral administration and quantified the number particles in several tissues. The brain inflammation was determined by measuring inflammatory cytokines by ELISA and real-time PCR. Mitochondrial membrane permeability of microglial cells was determined using JC-10 fluorescence dye. The in vivo apoptotic cell death was quantified by TUNEL assay. The brain metabolites were identified and quantified by LC-MS analysis. Memory function of the mice was determined by several memory functional analysis. The effect of GaELNs on glucose and insulin response of the mice was determined by glucose and insulin tolerance tests. c-Myc localization and interaction with BASP1 and calmodulin was determined by confocal microscopy. Results: Our results show that GaELNs is preferentially taken up microglial cells and inhibits the brain inflammation in HFD mice. GaELN phosphatidic acid (PA) (36:4) is required for the uptake of GaELNs via interaction with microglial BASP1. Formation of the GaELNs/BASP1 complex is required for inhibition of c-Myc mediated expression of STING. GaELN PA binds to BASP1, leading to inhibition of c-Myc expression and activity through competitively binding to CaM with c-Myc transcription factor. Inhibition of STING activity leads to reducing the expression of an array of inflammatory cytokines including IFN-γ and TNF-α. IFN-γ induces the expression of IDO1, which in turn the metabolites generated as IDO1 dependent manner activate the AHR pathway that contributes to developing obesity. The metabolites derived from the GaELNs treated microglial cells promote neuronal differentiation and inhibit mitochondrial mediated neuronal cell death. GaELNs treated HFD mice showed improved memory function and increased glucose tolerance and insulin sensitivity in these mice. Conclusion: Collectively, these results demonstrate how nanoparticles from a healthy diet can inhibit unhealthy high-fat diet induced brain inflammation and reveal a link between brain microglia/diet to brain inflammatory disease outcomes via diet-derived exosome-like nanoparticles.
