Abstract
Neuroinflammation is a complex biological process that typically originates as a protective response in the brain. This inflammatory process is triggered by the release of pro-inflammatory substances like cytokines, prostaglandins, and reactive oxygen and nitrogen species from stimulated endothelial and glial cells, including those with pro-inflammatory functions, in the outer regions. While neuronal inflammation is common in various central nervous system disorders, the specific inflammatory pathways linked with different immune-mediated cell types and the various factors influencing the blood-brain barrier significantly contribute to disease-specific characteristics. The endocannabinoid system consists of cannabinoid receptors, endogenous cannabinoids, and enzymes responsible for synthesizing and metabolizing endocannabinoids. The primary cannabinoid receptor is CB1, predominantly found in specific brain regions such as the brainstem, cerebellum, hippocampus, and cortex. The presence of CB2 receptors in certain brain components, like cultured cerebellar granular cells, Purkinje fibers, and microglia, as well as in the areas like the cerebral cortex, hippocampus, and cerebellum is also evidenced by immunoblotting assays, radioligand binding, and autoradiography studies. Both CB1 and CB2 cannabinoid receptors exhibit noteworthy physiological responses and possess diverse neuromodulatory capabilities. This review primarily aims to outline the distribution of CB1 and CB2 receptors across different brain regions and explore their potential roles in regulating neuroinflammatory processes.

Abstract
The Endocannabinoid System (ECS) is a well-studied system that influences a variety of physiological activities. It is evident that the ECS plays a significant role in metabolic activities and also has some neuroprotective properties. In this review, we emphasize several plant-derived cannabinoids such as β-caryophyllene (BCP), Cannabichromene (CBC), Cannabigerol (CBG), Cannabidiol (CBD), and Cannabinol (CBN), which are known to have distinctive modulation abilities of ECS. In Alzheimer's disease (AD), the activation of ECS may provide neuroprotection by modulating certain neuronal circuitry pathways through complex molecular cascades. The present article also discusses the implications of cannabinoid receptors (CB1 and CB2) as well as cannabinoid enzymes (FAAH and MAGL) modulators in AD. Specifically, CBR1 or CB2R modulations result in reduced inflammatory cytokines such as IL-2 and IL-6, as well as a reduction in microglial activation, which contribute to an inflammatory response in neurons. Furthermore, naturally occurring cannabinoid metabolic enzymes (FAAH and MAGL) inhibit the NLRP3 inflammasome complex, which may offer significant neuroprotection. In this review, we explored the multi-targeted neuroprotective properties of phytocannabinoids and their possible modulations, which could offer significant benefits in limiting AD.

Abstract
Psoriasis is linked with unusual differentiation and hyperproliferation of epidermal keratinocytes that significantly impair the quality of life (QoL) of patients. The present treatment options only provide symptomatic relief and are surrounded by various adverse effects. Recently, nanostructured lipid carriers (NLCs) have emerged as next-generation nanocarriers with better physicochemical characteristics. The current manuscript provides background information on psoriasis, its pathophysiology, existing treatment options, and its limitations. It highlights the advantages, rationale, and mechanism of the permeation of NLCs for the treatment of psoriasis. It further gives a detailed account of various NLC nanoformulations for the treatment of psoriasis. In addition, tabular information is provided on the most relevant patents on NLCs for treating psoriasis. Lastly, light is shed on regulatory considerations related to NLC-like nanoformulations. In the treatment of psoriasis, NLCs display a sustained release drug profile, an ability to incorporate both hydrophobic and hydrophilic drugs, an enhancement in skin hydration, penetrability, retention, and bioavailability of the drug, along with reduced staining potential as compared to conventional ointments, and decreased side effects of drug molecules. This affirms the bright future of NLC nanoformulations in the treatment of psoriasis. However, academic industry collaboration and more sound regulatory controls are required to commercialize the NLC nanoformulations for psoriasis treatment.

Abstract
BACKGROUND Diabetic foot ulcers (DFU) are one of the most serious complications in diabetic health treatment. The treatment for DFUs is more challenging, especially in individuals with a weakened immune system. Furthermore, due to developing antibiotic resistance characteristics among harmful bacteria and fungi, existing antibiotics may not be helpful in combating microbial infections in the wound site. OBJECTIVE This review will focus on the newest advances in antimicrobial treatments, such as dressings and topical therapies, as well as drugs and debridement methods. METHODS The English-language publications published on DFU were collected from a variety of sources, including Scopus, Web of Science, Bentham Science, Science Direct, and Google Scholar. RESULTS DFU therapy necessitates a multidisciplinary strategy including the use of appropriate diagnostic instruments, expertise, and experience. This begins with patient education and the use of new classifications to direct care in order to avoid amputations. To gain a deeper understanding of the microbiota in DFUs, new diagnostic approaches, such as the 16S ribosomal DNA sequence in bacteria, should become usable. CONCLUSION DFU is said to have a polymicrobial nature and, depending on its geographical area, some distinct characteristics, such as wound characteristics, antibiograms based on local epidemiology, individualized antimicrobial driven treatment, routine debridement, regular wound examination, and dressing changes. New biological and molecular therapies that have been shown to enhance infection prevention, the management of the local inflammatory profile, and the efficiency of the cicatrizing mechanism often help with the above characteristics.

Abstract
OBJECTIVES In the era of globalization, a sedentary lifestyle is highly linked with obesity and neurobehavioral complications such as depression. While depression is associated with dopamine dysfunction in the ventral tegmental area (VTA), ghrelin enhances the dopaminergic activity in the VTA. Therefore, the present study aimed to assess the effect of ghrelin on depression-like behaviour in rats subjected to a high-fat diet (HFD) and disturbed diurnal rhythm (DDR) for 45 days. METHODS The neurobehavioral deficits resulting from HFD and DDR in rats, and the behaviour modulation by intra-VTA administration of ghrelin, alone or in combination with ghrelin receptor antagonist were confirmed by evaluation of behavioural parameters in the elevated plus-maze, forced swim test, open field test, and rotarod assessment. Further, the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6, oxidative stress marker malondialdehyde (MDA), and antioxidants enzymes like superoxide dismutase (SOD), reduced glutathione (GSH), and catalase (CAT) were measured. RESULTS The levels of TNF-α, IL-1β, IL-6, and MDA were increased in the brain of HFD and DDR exposed rats, while that of SOD, GSH, and CAT were reduced. Intra-VTA ghrelin administration from day 41-45 to the HFD and DDR exposed rats improved cognitive behaviour and physical activity confirming the antidepressant effect. Moreover, ghrelin restored the levels of SOD, GSH and CAT efficiently, and reduced that of MDA, TNF-α, IL-1β and IL-6, which signifies its protective effect. CONCLUSION Overall, this study confirmed the ameliorative effect of ghrelin in HFD- and DDR-induced depression-like behaviour.

Abstract
Phloretin is a flavonoid of the dihydrogen chalcone class, present abundantly in apples and strawberries. The beneficial effects of phloretin are mainly associated with its potent antioxidant properties. Phloretin modulates several signaling pathways and molecular mechanisms to exhibit therapeutic benefits against various diseases including cancers, diabetes, liver injury, kidney injury, encephalomyelitis, ulcerative colitis, asthma, arthritis, and cognitive impairment. It ameliorates the complications associated with diabetes such as cardiomyopathy, hypertension, depression, memory impairment, delayed wound healing, and peripheral neuropathy. It is effective against various microbial infections including Salmonella typhimurium, Listeria monocytogenes, Mycobacterium tuberculosis, Escherichia coli, Candida albicans and methicillin-resistant Staphylococcus aureus. Considering the therapeutic benefits, it generated interest for the pharmaceutical development. However, poor oral bioavailability is the major drawback. Therefore, efforts have been undertaken to enhance its bioavailability by modifying physicochemical properties and molecular structure, and developing nanoformulations. In the present review, we discussed the pharmacological actions, underlying mechanisms and molecular targets of phloretin. Moreover, the review provides insights into physicochemical and pharmacokinetic characteristics, and approaches to promote the pharmaceutical development of phloretin for its therapeutic applications in the future. Although convincing experimental data are reported, human studies are not available. In order to ascertain its safety, further preclinical studies are needed to encourage its pharmaceutical and clinical development.

Abstract
Verapamil, a calcium channel blocker has poor bioavailability (20-30%) owing to extensive hepatic first-pass metabolism. Hence, the major objective of this research was to improve the oral bioavailability of Verapamil by Solid Lipid Nanoparticles (V-SLNs) using high shear homogenization and ultrasonication technology. A 32 factorial design was employed to statistically optimize the formulation to get minimum particle size with maximum entrapment efficiency. The average particle size was 218 nm and the entrapment efficiency was 80.32%. The V-SLN formulation exhibited biphasic behavior with a rapid release at first, then a steady release (75-80%) up to 24 h following the Korsmeyer Peppas release model. In the Isoproterenol induced myocardial necrosis model, oral administration of V-SLNs positively modulated almost all the studied hemodynamic parameters such as left ventricular end-diastolic pressure, cardiac injury markers, and tissue architecture. The cardioprotective effect was also confirmed with histopathological studies. When compared with free drugs, in-vivo pharmacokinetic studies demonstrated a rise in t1/2, AUC0-∞, and Cmax, indicating that bioavailability has improved. These encouraging results demonstrate the promising potential of developed V-SLNs for oral delivery and thereby improve the therapeutic outcome.

Abstract
Intranasal delivery has great potential to cross the blood-brain barrier and deliver the drug molecule into the central nervous system faster than traditional methods. The olfactory neuronal and trigeminal pathways both are involved in intranasal delivery. The nano-technology is an innovative strategy for the nose to brain delivery. The mucoadhesive nanoemulsion formulation is a modified technology that increases the duration of drug accumulation and provides prolonged delivery at a targeted site. The nanoemulsion formulation oil, surfactant, and co-surfactant components maintain lower surface tension and particle coalescence. The globule dimension and zeta potential are affected in brain targeting. The globule size of the innovative formulation should be < 200 nm for drug permeation because, in humans, the average axon magnitude ranges from around 100 to 700. Furthermore, modified technology of nanoemulsion like nanogel and nanoemulsion in-situ gel provide a great advantage to cure neurodegenerative disorders. Therefore, focusing on the innovative pharmaceutical approaches of nanoemulsion in intranasal drug delivery, the current review provides insight into the applications of nanoemulsion in neurodegenerative disorders like Parkinson's disease, which are due to the depletion of dopamine in substania nigra resulting in cardinal motor activity bradykinesia and tremors. The review also touches upon the pathways for intranasal delivery of nanoemulsion, the pathogenesis of Parkinson's disease, and the future direction of the research on intranasal nanoemulsion.

Abstract
Thymoquinone (TQ), the most prominent constituent of Nigella sativa seeds, essential oil, is reported to possess an organ protective effect via Nrf2 expression and activation of Phase-II antioxidant enzymes. Haemorrhagic cystitis is the sudden onset of haematuria combined with bladder pain and irritable bladder symptoms are the known toxic effects of cyclophosphamide (CYP) chemotherapy. The objective of the present study was to investigate and compare the protective effect of thymoquinone (TQ) and thymoquinone nanoparticles (TQ-NP) in the kidney against CYP-induced haemorrhagic cystitis. Primarily, TQ-NP was fabricated by synthesis of N-acetylated chitosan and nanoparticle preparation by the ionic gelation technique. They were characterized by particle size, polydispersive index (PDI), zeta potential, entrapment efficiency (EE), SEM, and dynamic scattering calorimetry (DSC). Moreover, fluorescein isothiocyanate (FITC) labeled NPs were prepared for biodistribution studies. The protective mechanisms of TQ-NP included its anti-inflammatory activity, inhibitory effects on cytokine levels, and protection against the DNA damage in the bladder epithelium. The cystitis was induced in rats by orally administering 200 mg/kg of CYP. The dose-dependent protective effect of the TQ-NP was determined by intravenously administering 1, 2, and 5 mg/kg of the TQ-NP to CYP-treated rats. The present study revealed that the TQ-NP prepared by ionic gelation method provides kidney targeted delivery of TQ as compared to TQ solution. The mean particle size, PDI, and %EE of TQ-NP were 272.6 nm, 0.216, 70.81 ± 0.12% respectively. The zeta potential of thymoquinone-loaded nanoparticles was found to be -20.7 mV and - 22.6 mV respectively before and after lyophilization. SEM study also confirmed the small size and spherical shape. Pharmacokinetic studies revealed the improvement in half-life and prolonged action of the TQ-NP as compared to the TQ solution. Also, TQ-NP administration showed more protection against the characteristic histological alterations in the bladder in comparison to TQ solution. The present study indicates that TQ-NP exerts potent anti-oxidant, DNA protective and cytokine inhibitory activity at considerably lower concentrations as compared to plain TQ solution. The nano formulation of TQ using N-acetylated chitosan provides effective kidney targeted delivery of TQ, which in turn improves its retention and protective efficacy against CYP-induced haemorrhagic cystitis.

Abstract
The endocannabinoid system (ECS) is natural physiological system in the humans. The presence of the ECS system involves different roles in body. The endocannabinoid system involves regulation of most of the centers, which regulates the hunger and leads to changes in the weight. In the present article, we reviewed the role of natural cannabinoid compounds in metabolic disorders and related complications. We studied variety of a plant-derived cannabinoids in treating the metabolic syndrome including stoutness, fatty acid liver diseases, insulin obstruction, dementia, hypertension, lipid abnormalities, non-alcoholic steatohepatitis, endothelial damage, and polycystic ovarian syndrome and so on. The activation of cannabinoid receptors demonstrates a significant number of beneficial approaches concerning metabolic syndrome and reduces the pro-inflammatory cytokines on account of aggravation, decreased oxidative stress and uneasiness, diminishes liver fibrosis, with reduces adiponectin. Pre-clinical investigations of plant-derived cannabinoids resulted in promising outcomes. The different distinctive plant-derived cannabinoids were discovered like cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), and cannabidiol (CBG). It has been observed that endogenous cannabinoids and plant-derived cannabinoids have an advantageous impact on limiting the metabolic disorder arising due to lifestyle changes.

Abstract
INTRODUCTION Methotrexate exhibits poor cutaneous bioavailability and systemic side effects on topical administration, so there is an unmet need for a novel carrier and its optimized therapy. Methotrexate-loaded nanostructured lipid carriers (MTXNLCs) were formulated and characterized to determine in vitro drug release and evaluate the role of MTXNLC gel in the topical treatment of psoriasis. METHODS A solvent diffusion technique was employed to prepare MTXNLCs, which was optimized using 32 full factorial designs. The mean diameter and surface morphology of MTXNLCs was evaluated. The crystallinity of lyophilized MTXNLCs was characterized by differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD). MTXNLCs were integrated in 1% w/w Carbopol 934 P gel base, and in vitro skin deposition studies in human cadaver skin (HCS) were carried out. RESULTS The optimized MTXNLCs were rod-shaped, with an average particle size of 253 ± 8.65 nm, a zeta potential of -26.4±0.86 mV, and EE of 54.00±1.49%. DSC and XRD data confirmed the formation of NLCs. Significantly higher deposition of MTX was found in HCS from MTXNLC gel (71.52 ±1.13%) as compared to MTX plain gel (38.48±0.96%). In vivo studies demonstrated significant improvement in therapeutic response and reduction in local side effects with MTXNLCs-loaded gel in the topical treatment of psoriasis. Anti-psoriatic efficacy of MTXNLCs 100 ug/cm2 compared with plain MTX gel was evaluated using imiquimod (IMQ)-induced psoriasis in BALB/c mice. The topical application of MTXNLCs to the mouse ear resulted in a significant reduction of psoriatic area and severity index, oxidative stress, inflammatory cytokines like TNF-α, IL-1β, and IL-6 and IMQ-induced histopathological alterations in mouse ear samples. CONCLUSION Developed formulation of MTXNLC gel demonstrated better anti-psoriatic activity and also displayed prolonged and sustained release effect, which shows that it can be a promising alternative to existing MTX formulation for the treatment of psoriasis.

Abstract
We investigated the eplerenone-induced, PI3K/Akt- and GSK-3β-mediated cardioprotection against ischemia/reperfusion (I/R) injury in diabetic rats. The study groups comprising diabetic rats were treated for 14 days with 150 mg/kg/day eplerenone orally and 1 mg/kg wortmannin (PI3K/Akt antagonist) intraperitoneally with eplerenone. On the 15th day, the rats were exposed to I/R injury by 20-min occlusion of the left anterior descending coronary artery followed by 30 min of reperfusion. The hearts were processed for biochemical, molecular, and histological investigations. The I/R injury in diabetic rats inflicted a significant rise in the oxidative stress and apoptosis along with a decrease in the arterial and ventricular function and the expressions of PI3K/Akt and GSK-3β proteins. Eplerenone pretreatment reduced the arterial pressure, cardiac inotropy, and lusitropy. It significantly reduced apoptosis and cardiac injury markers. The histology revealed cardioprotection in eplerenone-treated rats. Eplerenone up-regulated the PI3K/Akt and reduced the GSK-3β expression. The group receiving wortmannin with eplerenone was deprived eplerenone-induced cardioprotection. Our results reveal the eplerenone-induced cardioprotection against I/R injury in diabetic rats and substantiate the involvement of PI3K/Akt and GSK-3β pathways in its efficacy.

Abstract
Loss of pancreatic β-cell function is a hallmark of Type-II diabetes mellitus (DM). It is a chronic metabolic disorder that results from defects in both insulin secretion and insulin action. Recently, United Kingdom Prospective Diabetes Study reported that Type-II DM is a progressive disorder. Although, DM can be treated initially by monotherapy with oral agent; eventually, it may require multiple drugs. Additionally, insulin therapy is needed in many patients to achieve glycemic control. Pharmacological approaches are unsatisfactory in improving the consequences of insulin resistance. Single therapeutic approach in the treatment of Type-II DM is unsuccessful and usually a combination therapy is adopted. Increased understanding of biochemical, cellular and pathological alterations in Type-II DM has provided new insight in the management of Type-II DM. Knowledge of underlying mechanisms of Type-II DM development is essential for the exploration of novel therapeutic targets. Present review provides an insight into therapeutic targets of Type-II DM and their role in the development of insulin resistance. An overview of important signaling pathways and mechanisms in Type-II DM is provided for the better understanding of disease pathology. This review includes case studies of drugs that are withdrawn from the market. The experience gathered from previous studies and knowledge of Type-II DM pathways can guide the anti-diabetic drug development toward the discovery of clinically viable drugs that are useful in Type-II DM.

Abstract
The prevention of doxorubicin (Dox) induced cardiotoxicity may be co-operative to recover future Dox treatment. The aim of this study was to explore the cardioprotective effects of oleanolic acid (OA), an antioxidant agent, on Dox induced cardiotoxicity. OA is a triterpenoid compound, which exist widely in plant kingdom in free acid form or as a glycosidic triterpenoids saponins. Cardiotoxicity was induced in Wistar rats with single intravenous injection of doxorubicin at dose of 67.75 mg/kg i.v for 48 hrs. At 12 hrs of interval following Dox administration the cardioprotective effect of OA (1.5 mg/kg, i.v.) and Amifostine (AMF) (90 mg/kg i.v., single dose prior 30 min) were evaluated. Induction of cardiotoxicity was confirmed by increase in systolic, diastolic, mean arterial pressures, maximal positive rate of developed left ventricular pressure (+LVdP/dtmax, an indicator of myocardial contraction), maximal negative rate of developed left ventricular pressure (-LVdP/dtmax, a meter of myocardial relaxation) and an increase in left ventricular end-diastolic pressure (LVEDP, a marker of pre-load). Cardiac markers in such as CK-MB, LDH and alterations in ECG. Dox administration showed alteration in Biochemical parameters and endogenous antioxidants. Administration of OA Showed maximal protection against Dox induced cardiac toxicity as observed by reduction in blood pressure, prevention of left ventricular function and attenuation of biochemical and antioxidant parameters. Based on the findings, its concluded that OA can be used as an adjuvant with Dox therapy in treating cancers.

Abstract
Cardamom is a popular spice that has been commonly used in cuisines for flavor since ancient times. It has copious health benefits such as improving digestion, stimulating metabolism, and exhibits antioxidant and anti-inflammatory effects. The current study investigated the effect of cardamom on hemodynamic, biochemical, histopathological and ultrastructural changes in isoproterenol (ISO)-induced myocardial infarction. Wistar male albino rats were randomly divided and treated with extract of cardamom (100 and 200 mg/kg per oral) or normal saline for 30 days with concomitant administration of ISO (85 mg/kg, subcutaneous) on 29th and 30th days, at 24 h interval. ISO injections to rats caused cardiac dysfunction evidenced by declined arterial pressure indices, heart rate, contractility and relaxation along with increased preload. ISO also caused a significant decrease in endogenous antioxidants, superoxide dismutase, catalase, glutathione peroxidase, depletion of cardiomyocytes enzymes, creatine kinase-MB, lactate dehydrogenase and increase in lipid peroxidation. All these changes in cardiac and left ventricular function as well as endogenous antioxidants, lipid peroxidation and myocyte enzymes were ameliorated when the rats were pretreated with cardamom. Additionally, the protective effects were strengthened by improved histopathology and ultrastructural changes, which specifies the salvage of cardiomyocytes from the deleterious effects of ISO. The present study findings demonstrate that cardamom significantly protects the myocardium and exerts cardioprotective effects by free radical scavenging and antioxidant activities.

Abstract
Eplerenone is a competitive antagonist of the aldosterone receptor with an additional PI3K-Akt activity. The existing cram has been intended to explore, whether eplerenone treatment attenuates the expansion of myocardial infarction in isoproterenol treated rats by restoring hemodynamic, biochemical, and histopathological changes. Isoproterenol induced cardiotoxicity was evidenced by marked ST elevation, decrease in systolic, diastolic, mean arterial pressures. Maximal positive rate of developed left ventricular pressure (+LVdP/dt max, a indicator of myocardial contraction), maximal negative rate of developed left ventricular pressure (-LVdP/dt max, a meter of myocardial relaxation) and an increase in left ventricular end-diastolic pressure (LVEDP, a marker of pre-load) were also shown. In addition, a significant reduction in activities of myocardial creatine kinase-MB isoenzyme, lactate dehydrogenase, superoxide dismutase, catalase, and reduced glutathione level along with increase in malondialdehyde content were observed. Oral pre-treatment with eplerenone (50, 100 and 150 mg/kg) daily for a period of 14 days, constructively modulated the studied parameters in isoproterenol-induced myocardial injury. The protective role of eplerenone on isoproterenolinduced myocardial damage was further confirmed by histopathological examinations. Eplerenone at doses of 100 mg/kg and 150 mg/kg produced more pronounced protective effects than 50 mg/kg body weight. Together, our study provides evidence for protective effects of eplerenone on myocardium in experimentally induced myocardial infarction.

Abstract
The present study investigated the effect of hesperidin, a natural flavonoid, in cardiac ischemia and reperfusion (I/R) injury in diabetic rats. Male Wistar rats with diabetes were divided into five groups and were orally administered saline once daily (IR-sham and IR-control), Hesperidin (100 mg/kg/day; IR-Hesperidin), GW9962 (PPAR-γ receptor antagonist), or combination of both for 14 days. On the 15th day, in the IR-control and IR-treatment groups, rats were subjected to left anterior descending (LAD) coronary artery occlusion for 45 minutes followed by a one-hour reperfusion. Haemodynamic parameters were recorded and rats were sacrificed; hearts were isolated for biochemical, histopathological, ultrastructural and immunohistochemistry. In the IR-control group, significant ventricular dysfunctions were observed along with enhanced expression of pro-apoptotic protein Bax. A decline in cardiac injury markers lactate dehydrogenase activity, CK-MB and increased content of thiobarbituric acid reactive substances, a marker of lipid peroxidation, and TNF-α were observed. Hesperidin pretreatment significantly improved mean arterial pressure, reduced left ventricular end-diastolic pressure, and improved both inotropic and lusitropic function of the heart (+LVdP/dt and –LVdP/dt) as compared to IR-control. Furthermore, hesperidin treatment significantly decreased the level of thiobarbituric acid reactive substances and reversed the activity of lactate dehydrogenase towards normal value. Hesperidin showed anti-apoptotic effects by upregulating Bcl-2 protein and decreasing Bax protein expression. Additionally, histopathological and ultrastructural studies reconfirmed the protective action of hesperidin. On the other hand, GW9662, selective PPAR-γ receptor antagonist, produced opposite effects and attenuated the hesperidin induced improvements. The study for the first time evidence the involvement of PPAR-γ pathway in the cardioprotective activity of hesperidin in I/R model in rats.
