Coenzyme Q10 ameliorates chemotherapy-induced cognitive impairment in mice: a preclinical study.

BACKGROUND: Among the three most used anticancer drugs, cyclophosphamide, Adriamycin, and 5-Fluorouracil (CAF), the most significant outcome is chemobrain, caused by increased oxidative stress, inflammatory insult, and mitochondrial dysfunction. OBJECTIVE: In this study, endogenous antioxidant coenzyme Q10 (CoQ10) was evaluated for its neuroprotective effects in CICI. MATERIALS AND METHODS: The chemobrain was induced in Swiss albino female mice by administering CAF (40 + 4 + 25 mg/kg) intraperitoneal (i.p.) in three cycles (single injection per week) followed by treatment with CoQ10 (40 mg/kg; p.o.) for up to 3 weeks followed by behavioral, biochemical, molecular and histopathological analysis. RESULTS: Treatment with CoQ10 significantly improved cognition by improving exploring time in novel objects recognition test followed by increasing the time spent in the target quadrant in MWM test as compared to CAF-treated animals. Moreover, CoQ10 demonstrated antioxidant properties by reducing the expression of LPO while increasing levels of GSH, SOD, and catalase as compared to CAF-treated animals. While the levels of AChEs were significantly reduced after CoQ10 treatment in CAF-treated animals. In terms of its mechanism, it effectively counteracted the pro-inflammatory substances (TNF-α and IL-1ß) triggered by CAF while also enhancing the levels of anti-inflammatory markers (IL-10 and Nrf2). Moreover, CoQ10 showed mitochondrial enhancers and it improved the level of Complex (I, II, and IV). Besides that, mitochondrial morphological analysis was done by TEM, and neuronal morphology along with quantification analysis was performed by H&E staining using Image J software to confirm the neuroprotective effect of CoQ10 over CAF-induced cognitive impairment. CONCLUSION: This study suggests CoQ10 can protect the mitochondria by imposing antioxidant, and anti-inflammatory properties, which could be a potential therapy for CICI.

Brain resident microglia in Alzheimer's disease: foe or friends.

The neurobiology of Alzheimer's disease (AD) is unclear due to its multifactorial nature. Although a wide range of studies revealed several pathomechanisms of AD, dementia is yet unmanageable with current pharmacotherapies. The recent growing literature illustrates the role of microglia-mediated neuroinflammation in the pathogenesis of AD. Indeed, microglia serve as predominant sentinels of the brain, which diligently monitor the neuroimmune axis by phagocytosis and releasing soluble factors. In the case of AD, microglial cells are involved in synaptic pruning and remodeling by producing inflammatory mediators. The conditional inter-transformation of classical activation (proinflammatory) or alternative activation (anti-inflammatory) microglia is responsible for most brain disorders. In this review, we discussed the role of microglia in neuroinflammatory processes in AD following the accumulation of amyloid-ß and tau proteins. We also described the prominent phenotypes of microglia, such as disease-associated microglia (DAM), dark microglia, interferon-responsive microglia (IRMs), human AD microglia (HAMs), and microglial neurodegenerative phenotype (MGnD), which are closely associated with AD incidence. Considering the key role of microglia in AD progression, microglial-based therapeutics may hold promise in mitigating cognitive deficits by addressing the neuroinflammatory responses.

The Role of Mitophagy in Various Neurological Diseases as a Therapeutic Approach.

Mitochondria are critical to multiple cellular processes, from the production of adenosine triphosphate (ATP), maintenance of calcium homeostasis, synthesis of key metabolites, and production of reactive oxygen species (ROS) to maintain necrosis, apoptosis, and autophagy. Therefore, proper clearance and regulation are essential to maintain various physiological processes carried out by the cellular mechanism, including mitophagy and autophagy, by breaking down the damaged intracellular connections under the influence of various genes and proteins and protecting against various neurodegenerative diseases such as Parkinson disease (PD), amyotrophic lateral sclerosis (ALS), Alzheimer disease (AD), and Huntington disease (HD). In this review, we will discuss the role of autophagy, selective macroautophagy, or mitophagy, and its role in neurodegenerative diseases along with normal physiology. In addition, this review will provide a better understanding of the pathways involved in neuron autophagy and mitophagy and how mutations affect these pathways in the various genes involved in neurodegenerative diseases. Various new findings indicate that the pathways that remove dysfunctional mitochondria are impaired in these diseases, leading to the deposition of damaged mitochondria. Apart from that, we have also discussed the therapeutic strategies targeting autophagy and mitophagy in neurodegenerative diseases. The mitophagy cycle results in the degradation of damaged mitochondria and the biogenesis of new healthy mitochondria, also highlighting different stages at which a particular neurodegenerative disease could occur.

Blood-Brain Barrier Dysfunction in Hypertensive Disorders of Pregnancy.

PURPOSE OF REVIEW: The incidence of hypertensive disorders of pregnancy (HDP), especially preeclampsia has increased significantly over the last two decades. Patients with these disorders often report cerebral and visual symptoms, which are listed as potential diagnosis criteria for preeclampsia, if accompanied by new-onset hypertension. Recent studies indicate that cerebral complications in HDP patients are associated with a compromised blood-brain barrier (BBB). The purpose of this review is to highlight the recent literature focused on the BBB in HDP, identify gaps in knowledge, and discuss future directions in this research area. RECENT FINDINGS: Majority of the studies addressing BBB changes in HDP are focused on preeclampsia. Recent studies show that hypertension induces increased association of perivascular macrophages/microglia to the cerebral vessels, increased circulating extracellular vesicles, and decreased autoregulation of cerebral blood flow. There is a critical need for more animal studies targeted to protecting the BBB and preventing cerebrovascular complications in the context of HDP. More clinical studies are needed that investigate both the short- and long-term interplay between each HDP subtype and BBB and cognitive function.

Online Interest for Electronic Cigarettes Using Google Trends in the UK: A Correlation Analysis.

BACKGROUND: Google Trends provides an easily accessible and cost-effective method of providing real-time insight into user interest. OBJECTIVE: to address the gap in UK prevalence data for e-cigarettes by analyzing Google Trends to identify correlations with official data from Action on Smoking and Health. The study further evaluates Google Trend's sensitivity to real-time events and the ability for predictive models to forecast future data based on Google Trends. METHODS: UK Google Trends data from 2012 to 2021 was analyzed to assess (a) the most popular electronic nicotine device terminology; (b) statistically significant points in time; (c) correlations between Relative Search Volumes and official reports on electronic cigarette use and (d) whether Google Trends could predict future patterns in data. These were achieved using Locally Weighted Scatterplot Smoothing regression, Pruned Exact Linear Time Method, cross correlation, and Autoregressive Integrated Moving Average algorithms respectively. RESULTS: "Vape" was revealed to be the most popular electronic nicotine device terminology with a correlation coefficient greater than +0.9 when compared to official electronic cigarette consumption data within a one-year timescale (lag 0). Results from ARIMA modeling were varied with the algorithms forecasted trends line occasionally lying outside of a 95% prediction interval. CONCLUSION: Google Trends may correspond to population-based prevalence of electronic cigarette use. The changing trends coincide with changing policy decisions. Google Trends based prediction for online interest in electronic cigarettes requires further validation so should currently be used in conjunction with other traditional methods of data collections.

Response of the plant core microbiome to Fusarium oxysporum infection and identification of the pathobiome.

Plant core microbiomes consist of persistent key members that provide critical host functions, but their assemblages can be interrupted by biotic and abiotic stresses. The pathobiome is comprised of dynamic microbial interactions in response to disease status of the host. Hence, identifying variation in the core microbiome and pathobiome can significantly advance our understanding of microbial-microbial interactions and consequences for disease progression and host functions. In this study, we combined glasshouse and field studies to analyse the soil and plant rhizosphere microbiome of cotton plants (Gossypium hirsutum) in the presence of a cotton-specific fungal pathogen, Fusarium oxysporum f. sp. vasinfectum (FOV). We found that FOV directly and consistently altered the rhizosphere microbiome, but the biocontrol agents enabled microbial assemblages to resist pathogenic stress. Using co-occurrence network analysis of the core microbiome, we identified the pathobiome comprised of the pathogen and key associate phylotypes in the cotton microbiome. Isolation and application of some negatively correlated pathobiome members provided protection against plant infection. Importantly, our field survey from multiple cotton fields validated the pattern and responses of core microbiomes under FOV infection. This study advances key understanding of core microbiome responses and existence of plant pathobiomes, which provides a novel framework to better manage plant diseases in agriculture and natural settings.

Google Trends Data: A Potential New Tool for Monitoring the Opioid Crisis.

INTRODUCTION: There is a need to strengthen the standard surveillance of the opioid overdose crisis in the USA. The role of Google Trends (GT) was explored in this context. METHODS: In this study, a systemic GT search was done for a period from January 2004 to December 2018. "Naloxone" and "drug overdose" were chosen as search inputs. By using locally weighted scatterplot smoothing, we locally regressed and smoothed the relative search data generated by the GT search. We conducted a changepoint analysis (CPA) to detect significant statistical changes in the "naloxone" trend from 2004 to 2018. Cross-correlation function analyses were done to examine the correlation between 2 time series: year-wise relative search volume (RSV) for "naloxone" and "drug overdose" with the age-adjusted drug overdose mortality rate. Pearson's correlation was performed for the state-wise age-adjusted mortality rate due to drug overdose and RSV for "naloxone" and "drug overdose." RESULTS: Smoothed and regressed GT of "naloxone" were similar to the "opioid overdose" trend published by the National Center for Health Statistics. The CPA showed 2 statistically significant points in 2011 and 2015. CPA of year-wise RSV for "naloxone" and "drug overdose" showed significantly positive correlation with the age-adjusted drug overdose mortality at lag zero. State-wise RSV for "naloxone" and "drug overdose" too showed a strong and significant positive correlation with the state-wise mortality data. DISCUSSION/CONCLUSION: Inexpensive, publicly accessible, real-time GT data could supplement and strengthen the monitoring of opioid overdose epidemic if used in conjunction with the existing official data sources.

Characterization of oleosin genes from forage sorghum in Arabidopsis and yeast reveals their role in storage lipid stability.

MAIN CONCLUSION: Overexpression of forage sorghum oleosin genes in Arabidopsis oleosin-deficient mutant and yeast showed increased germination rate, triacylglycerol content, and protection against lipase-mediated TAG degradation. Plant lipids are an important source of ration for cattle or other livestock animals to fulfil their energy needs. Poor energy containing green forages are still one of the major sources of food for livestock animals, leaving the animals undernourished. This lowers the milk and meat production efficiency, thereby affecting human consumption. Oleosin, an essential oil body surface protein, is capable of enhancing and stabilizing the lipid content in plants. We identified and functionally characterized three forage sorghum oleosin genes (SbOle1, SbOle2, and SbOle3) in Arabidopsis and yeast. Phylogenetic analysis of SbOle proteins showed a close relationship with rice and maize oleosins. Expression analysis of SbOle genes determined a higher expression pattern in embryo followed by endosperm, while its expression in the non-seed tissues remained negligible. Overexpression of SbOle genes in Arabidopsis ole1-deficient mutants showed restoration of normal germination whereas control mutant seeds showed lower germination rates. Heterologous overexpression of SbOle in yeast cells resulted in increased TAG accumulation. Additionally, the TAG turnover assay showed the effectiveness of SbOle genes in reducing the yeast endogenous and rumen bacterial lipase-mediated TAG degradation. Taken together, our findings not only provide insights into forage sorghum oleosin for increasing the energy content in non-seed organs but also opened up the direction towards implication of oleosin in rumen protection of fodders.

Use and interest of electronic nicotine delivery systems (ENDS): Assessing the validity of Google Trends.

Background: Initial evidence suggests a role for Google Trends (GT) in monitoring use and interest in Electronic Nicotine Delivery Systems (ENDS).Objective: To examine the validity of GT data for assessing population behavior and interest in ENDS.Methods: GT search, done from the US and India to assess: (a) whether descriptive and statistical trends of specific search words depicting online interest in ENDS were similar to the published reports on actual use of these products in the US; (b) correlations between state-wise relative search volumes (RSV) of these words and prevalence of ENDS use; (c) the change in the online interest of ENDS after change in its regulatory policy.Results: Locally weighted scatter plot analysis showed "electronic cigarette," "vaping," and "cigarette" trends mirrored the use trend reported by the US-based National Youth Tobacco Survey (2019). Online interest in "Juul pods" followed the trends of its use. Geo-spatial RSVs of "electronic cigarette" (r=0.74, p<0.0001) and "vaping" (r=0.55, p<0.0001) correlated positively with state-wise prevalence of switch to ENDS in adults. Complete ENDS use prohibition in India was associated with a decrease in the online interest in "electronic cigarettes" (t=3.18, p=0.01) and "vaping" (t=2.3, p=0.04). Regulation of use in New Mexico (USA) was associated with a reduction in "electronic cigarettes" (t=4.09, p=0.0005) but not in "vaping."Conclusion: GT may be used to validate existing information and assess the potential effect of ENDS regulations. Its role can also be extended for monitoring interest and use of other drugs and alcohol.

Informing Environmental Water Management Decisions: Using Conditional Probability Networks to Address the Information Needs of Planning and Implementation Cycles.

One important aspect of adaptive management is the clear and transparent documentation of hypotheses, together with the use of predictive models (complete with any assumptions) to test those hypotheses. Documentation of such models can improve the ability to learn from management decisions and supports dialog between stakeholders. A key challenge is how best to represent the existing scientific knowledge to support decision-making. Such challenges are currently emerging in the field of environmental water management in Australia, where managers are required to prioritize the delivery of environmental water on an annual basis, using a transparent and evidence-based decision framework. We argue that the development of models of ecological responses to environmental water use needs to support both the planning and implementation cycles of adaptive management. Here we demonstrate an approach based on the use of Conditional Probability Networks to translate existing ecological knowledge into quantitative models that include temporal dynamics to support adaptive environmental flow management. It equally extends to other applications where knowledge is incomplete, but decisions must still be made.

Intricate Role of the Cyclic Guanosine Monophosphate Adenosine Monophosphate Synthase-Stimulator of Interferon Genes (cGAS-STING) Pathway in Traumatic Brain Injury-Generated Neuroinflammation and Neuronal Death.

The secondary insult in the aftermath of traumatic brain injury (TBI) causes detrimental and self-perpetuating alteration in cells, resulting in aberrant function and the death of neuronal cells. The secondary insult is mainly driven by activation of the neuroinflammatory pathway. Among several classical pathways, the cGAS-STING pathway, a primary neuroinflammatory route, encompasses the cyclic GMP-AMP synthase (cGAS), stimulator of interferon genes (STING), and downstream signaling adaptor. Recently, the cGAS-STING research domain has gained exponential attention. The aberrant stimulation of cGAS-STING machinery and corresponding neuroinflammation have also been reported after TBI. In addition to the critical contribution to neuroinflammation, the cGAS-STING signaling also provokes neuronal cell death through various cell death mechanisms. This review highlights the structural and molecular mechanisms of the cGAS-STING machinery associated with TBI. We also focus on the intricate relationship and framework between cGAS-STING signaling and cell death mechanisms (autophagy, apoptosis, pyroptosis, ferroptosis, and necroptosis) in the aftermath of TBI. We suggest that the targeting of cGAS-STING signaling may open new therapeutic strategies to combat neuroinflammation and neurodegeneration in TBI.

Role of Autophagy and Mitophagy in Neurodegenerative Disorders.

Autophagy is a self-destructive cellular process that removes essential metabolites and waste from inside the cell to maintain cellular health. Mitophagy is the process by which autophagy causes disruption inside mitochondria and the total removal of damaged or stressed mitochondria, hence enhancing cellular health. The mitochondria are the powerhouses of the cell, performing essential functions such as ATP (adenosine triphosphate) generation, metabolism, Ca2+ buffering, and signal transduction. Many different mechanisms, including endosomal and autophagosomal transport, bring these substrates to lysosomes for processing. Autophagy and endocytic processes each have distinct compartments, and they interact dynamically with one another to complete digestion. Since mitophagy is essential for maintaining cellular health and using genetics, cell biology, and proteomics techniques, it is necessary to understand its beginning, particularly in ubiquitin and receptor-dependent signalling in injured mitochondria. Despite their similar symptoms and emerging genetic foundations, Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) have all been linked to abnormalities in autophagy and endolysosomal pathways associated with neuronal dysfunction. Mitophagy is responsible for normal mitochondrial turnover and, under certain physiological or pathological situations, may drive the elimination of faulty mitochondria. Due to their high energy requirements and post-mitotic origin, neurons are especially susceptible to autophagic and mitochondrial malfunction. This article focused on the importance of autophagy and mitophagy in neurodegenerative illnesses and how they might be used to create novel therapeutic approaches for treating a wide range of neurological disorders.

Risk factors and etiology of early-onset neonatal sepsis in Northeastern part of India: Case-control study.

Background: Sepsis, the second most common cause of neonatal mortality, causes more than one million deaths annually. India has the highest incidence of clinical sepsis (17000/100000 live birth). Objective: This study aimed to determine the risk factors and organisms of early-onset neonatal sepsis (EONS) in a tertiary care hospital in Northeast India. Materials and Methods: It was a case-control study conducted in the neonatal unit of MGM Medical College, Kishanganj, Bihar, from January 2022 to April 2023. All neonates admitted to the neonatal intensive care unit (NICU) within 72 hours of life constituted the study population. Neonates diagnosed as EONS by clinical and laboratory parameters were considered as cases and those not diagnosed for EONS as controls. Maternal and newborn information and laboratory parameters were collected and analyzed. For risk factor identification, the bivariate logistic regression was used. Result: An equal number of cases (78) and control (78) were enrolled in the study. Maternal age >30 years (adjusted odds ratio [aOR] = 3.017, confidence interval [CI]: 1.238 to 7.352; P < 0.015), maternal urinary tract infection (UTI) in the third trimester (aOR = 5.435, CI: 2.647 to 11.158; P < 0.0001), and premature rupture of membranes (PROM) (aOR = 2.918, CI: 4.61 to 33.73, P < 0.004) were significant predictors of EONS. Pseudomonas (41.02%), Klebsiella (16.66%), and coagulase-negative Staphylococcus aureus (20.51%) were commonly isolated organisms, which were highly resistant to cephalosporin, meropenem, aminoglycosides, and quinolones. Conclusion: Proper and adequate antenatal screening for diagnosis and treatment of maternal infection and high-risk pregnancies for perinatal management of newborn is recommended to prevent neonatal sepsis-related morbidity and mortality. Rational use of antibiotics may minimize the hazard of antibiotic resistance.

Enhanced antichemobrain activity of amino acid assisted ferulic acid solid dispersion in adult zebrafish (Danio rerio).

Chemotherapy-induced cognitive impairment (CICI), also known as "chemobrain," is a common side effect of breast cancer therapy which causes oxidative stress and generation of reactive oxygen species (ROS). Ferulic acid (FA), a natural polyphenol, belongs to BCS class II is confirmed to have nootropic, neuroprotective and antioxidant effects. Here, we have developed FA solid dispersion (SD) in order to enhance its therapeutic potential against chemobrain. An amorphous ferulic acid loaded leucin solid dispersion (FA-Leu SD) was prepared by utilizing amino acid through spray-drying technique. The solid-state characterization was carried out via Fourier-transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and field emission scanning electron microscopy (FE-SEM). Additionally, in-vitro release studies and antioxidant assay were also performed along with in-vivo locomotor, biochemical and histopathological analysis. The physical properties showed that FA-Leu SD so formed exhibited spherical, irregular surface hollow cavity of along with broad melting endotherm as observed from FE-SEM and DSC results. The XRD spectra demonstrated absence of sharp and intense peaks in FA-Leu SD which evidenced for complete encapsulation of drug into carrier. Moreover, in-vitro drug release studies over a period of 5 h in PBS (pH 7.4) displayed a significant enhanced release in the first hr (68. 49 ± 5.39%) and in-vitro DPPH assay displayed greater antioxidant potential of FA in FA-Leu SD. Furthermore, the in-vivo behavioral findings of FA-Leu SD (equivalent to 150 mg/kg of free FA) exhibited positive results accompanied by in-vivo biochemical and molecular TNF-α showed a significant difference (p < 0.001) vis-à-vis DOX treated group upon DOX + FA-Leu SD. Additionally, histopathological analysis revealed neuroprotective effects of FA-Leu SD together with declined oxidative stress due to antioxidant potential of FA which was induced by anticancer drug doxorubicin (DOX). Overall, the above findings concluded that spray-dried FA-Leu SD could be useful for the treatment of chemotherapy induced cognitive impairment.

Effect of minimally invasive treatment for intrabony defects using Bio-Oss® collagen.

The potential of Bio-Oss® collagen xenograft for treating intrabony defects using minimally invasive surgical methods is of interest. Hence, 30 defect sites in individuals with mild to severe chronic periodontitis were investigated. Participants were randomly divided into two groups of 15 each. Group A underwent regenerative MIST (minimally invasive surgical technique) with a bovine-derived xenograft, while Group B received only MIST. Periodontal parameters, including plaque index, gingival index, probing pocket depth, clinical attachment levels, and intrabony defect fill, were evaluated at three and six-month intervals. Significant improvements in periodontal parameters were observed in both groups, with Group A showing significantly better results.

Trends of Buprenorphine Prescribing for Opioid Dependence Before, and During the Early and Later Part of the COVID-19: A Study from a Large Publicly-Funded Opioid Agonist Treatment Services in India.

BACKGROUND: The COVID-19 pandemic has affected the availability and access to medications for opioid dependence (OD). We examined the monthly trends in new buprenorphine/naloxone (BNX) treatment episodes, number of clinical visits for BNX, BNX dispensed per person, and BNX prescription over 56-month, which included pre-pandemic, during early, and later part of pandemic (Jan 2017 - Aug 2022). METHODS: Research data were collected from the pharmacy database of a large publicly funded treatment center in India. A flexible, low-threshold service was adopted in April 2020 in response to the lockdown implemented on 25 March 2020. Change Point analyses were performed to examine monthly trends visually and statistically. We used Autoregressive integrated moving averages to forecast trends from April to Aug 2020 and March to August 2022, using Jan 2017 to March 2020 and March 2020 to February 2022 as training datasets. RESULTS: 993 patients were started on BNX treatment, 40452 BNX clinic attendances were made, 1401393 BNX tablets were dispensed, and 6795 new patients with OD were registered. The observed data for clinic attendance for BNX was significantly lower than the projected estimates in April -Aug 2020; however, observed new treatment episodes and monthly BNX prescriptions were within the 95% projected estimates; BNX dispensed per person was significantly more than the projected estimate. In contrast, observed BNX prescription trends surpassed the upper limit of 95% CI in March-Aug 2022. CONCLUSION: A low-threshold and flexible treatment service could mitigate the unintended consequences of pandemic-induced restrictions.

Polymer-mediated nanoformulations: a promising strategy for cancer immunotherapy.

Engineering polymer-based nano-systems have attracted many researchers owing to their unique qualities like shape, size, porosity, mechanical strength, biocompatibility, and biodegradability. Both natural and synthetic polymers can be tuned to get desired surface chemistry and functionalization to improve the efficacy of cancer therapy by promoting targeted delivery to the tumor site. Recent advancements in cancer immunoediting have been able to manage both primary tumor and metastatic lesions via activation of the immune system. The combinations of nano-biotechnology and immunotherapeutic agents have provided positive outcomes by enhancing the host immune response in cancer therapy. The nanoparticles have been functionalized using antibodies, targeted antigens, small molecule ligands, and other novel agents that can interact with biological systems at nanoscale levels. Several polymers, such as polyethylene glycol (PEG), poly(lactic-co-glycolic acid) (PLGA), poly(ε-caprolactone) (PCL), and chitosan, have been approved by the Food and Drug Administration for clinical use in biomedicine. The polymeric nanoformulations such as polymers-antibody/antigen conjugates and polymeric drug conjugates are currently being explored as nanomedicines that can target cancer cells directly or target immune cells to promote anti-cancer immunotherapy. In this review, we focus on scientific developments and advancements on engineered polymeric nano-systems in conjugation with immunotherapeutic agents targeting the tumor microenvironment to improve their efficacy and the safety for better clinical outcomes.

In-vitro and in-vivo studies of two-drug cocktail therapy targeting chemobrain via the Nrf2/NF-κB signaling pathway.

Today, we critically need alternative therapeutic options for chemotherapy-induced cognitive impairment (CICI), often known as chemo brain. Mitochondrial dysfunction and oxidative stress are two of the primary processes that contribute to the development of chemobrain. Therefore, the purpose of this study was to investigate how CoQ10 and berberine shield neurons from chemotherapy-induced damage in in-vitro studies and memory loss in vivo studies. For the in-vitro investigation, we employed SH-SY5Y cell lines, and for the in-vivo study, we used female Swiss albino mice divided into seven different groups. Data from in-vitro studies revealed that treatment with coenzyme Q10 (CoQ10) and berberine improved chemotherapy-induced toxicity by reducing mitochondrial and total cellular ROS, as well as apoptosis-elicited markers (caspase 3 and 9). CoQ10 and berberine therapy inhibited the nuclear translocation of NF-κB and, consequently, the subsequent expressions of NLRP3 and IL-1ß, implying the prevention of inflammasome formation. Furthermore, CoQ10 and berberine therapy boosted Nrf2 levels. This is a regulator for cellular resistance to oxidants. The in vivo results showed that treatment with CoQ10 (40 mg/kg) and berberine (200 mg/kg) improved the behavioral alterations induced by CAF (40/4/25 mg/kg) in both the Morris Water Maze (MWM) and Novel Object Recognition (NOR) tests. Furthermore, biochemical and molecular evidence revealed the antioxidant, mitochondrial restorative, and anti-inflammatory potential of CoQ10 (40 mg/kg) and berberine (200 mg/kg) against CAF (40/4/25 mg/kg) subjected mice. In addition, the histological analysis using H&E staining and transmission electron microscopy (for mitochondrial morphology) showed that mice treated with the cocktails had an increased number of healthy neurons with intact mitochondria and a reduced presence of autophagic vacuoles in the hippocampal region of the brain. These findings back up our theory about this novel cocktail method for CAF-induced cognitive impairment.

Unearthing the power of microbes as plant microbiome for sustainable agriculture.

In recent years, research into the complex interactions and crosstalk between plants and their associated microbiota, collectively known as the plant microbiome has revealed the pivotal role of microbial communities for promoting plant growth and health. Plants have evolved intricate relationships with a diverse array of microorganisms inhabiting their roots, leaves, and other plant tissues. This microbiota mainly includes bacteria, archaea, fungi, protozoans, and viruses, forming a dynamic and interconnected network within and around the plant. Through mutualistic or cooperative interactions, these microbes contribute to various aspects of plant health and development. The direct mechanisms of the plant microbiome include the enhancement of plant growth and development through nutrient acquisition. Microbes have the ability to solubilize essential minerals, fix atmospheric nitrogen, and convert organic matter into accessible forms, thereby augmenting the nutrient pool available to the plant. Additionally, the microbiome helps plants to withstand biotic and abiotic stresses, such as pathogen attacks and adverse environmental conditions, by priming the plant's immune responses, antagonizing phytopathogens, and improving stress tolerance. Furthermore, the plant microbiome plays a vital role in phytohormone regulation, facilitating hormonal balance within the plant. This regulation influences various growth processes, including root development, flowering, and fruiting. Microbial communities can also produce secondary metabolites, which directly or indirectly promote plant growth, development, and health. Understanding the functional potential of the plant microbiome has led to innovative agricultural practices, such as microbiome-based biofertilizers and biopesticides, which harness the power of beneficial microorganisms to enhance crop yields while reducing the dependency on chemical inputs. In the present review, we discuss and highlight research gaps regarding the plant microbiome and how the plant microbiome can be used as a source of single and synthetic bioinoculants for plant growth and health.
