Oral administration is the exclusive method for utilizing the potent third-generation antiepileptic drug perampanel. Potentially, PER could be a valuable tool in the management of anxieties as a component of epilepsy treatment. Our previous findings revealed that the intranasal (IN) administration of PER, incorporated into a self-microemulsifying drug delivery system (SMEDDS), led to enhanced brain targeting and exposure in mice. The PER biodistribution in the mouse brain, its anticonvulsant and anxiolytic properties, and potential olfactory and neuromuscular toxicity were studied after the intraperitoneal injection of 1 mg/kg. When given intranasally, PER demonstrated a characteristic rostral-caudal brain biodistribution pattern. click here High levels of PER were observed in the olfactory bulbs shortly after post-nasal dosing, with olfactory bulb/plasma ratios of 1266.0183 and 0181.0027 for intranasal and intravenous routes, respectively. This strongly implies a fraction of the drug is conveyed to the brain through the olfactory system. The maximal electroshock seizure test revealed that intraperitoneally administered PER protected 60% of the mice from seizure development, a significantly higher percentage than the 20% protection obtained by mice administered oral PER. PER exhibited anxiolytic effects, as evidenced by its performance in the open field and elevated plus maze. The buried food-seeking test yielded no indication of olfactory toxicity. The rotarod and open field tests indicated neuromotor impairments at the times of highest PER concentrations post-intraperitoneal and oral administration. Nonetheless, repeated applications enhanced neuromotor function. Intra-IN administration of the compound, in comparison with intra-vehicle administration, saw a decrease in brain L-glutamate (091 013 mg/mL compared to 064 012 mg/mL) and nitric oxide (100 1562% compared to 5662 495%), with no observable changes in GABA levels. In conclusion, these results indicate that intranasal drug delivery through the developed SMEDDS platform is a potentially safe and promising alternative to oral treatments, supporting further clinical trials exploring its effectiveness in managing epilepsy and associated neurological conditions like anxiety.
Because of glucocorticoids' (GCs) pronounced anti-inflammatory effect, they are utilized in the therapy of practically all inflammatory lung diseases. Intrapulmonary delivery of GC (IGC) allows for potent drug concentrations in the respiratory system, and this localized action may lessen systemic side effects. The highly absorbent nature of the lung epithelium's surface can potentially limit the success of localized therapy by enabling rapid absorption. In view of this, a strategy of inhaling GC that is part of a nanocarrier system could potentially address this constraint. For pulmonary GC delivery via inhalation, lipid nanocarriers, renowned for their high pulmonary biocompatibility within the pharmaceutical domain, hold the greatest potential. This review considers preclinical investigations of inhaled GC-lipid nanocarriers, highlighting the key determinants of local pulmonary GC delivery effectiveness: 1) nebulization resistance, 2) pulmonary deposition patterns, 3) mucociliary clearance, 4) targeted cellular accumulation, 5) prolonged lung retention, 6) systemic absorption profile, and 7) biocompatibility. Finally, a discussion ensues regarding novel preclinical pulmonary models applicable to inflammatory lung diseases.
Globally, oral cancer diagnoses amount to over 350,000, with 90% comprising oral squamous cell carcinoma (OSCC). Chemoradiation's current applications lead to disappointing results and have detrimental consequences for surrounding healthy tissues. Erlotinib (ERB) was the therapeutic agent of interest in this study, aiming to treat oral cavity tumor locations locally. Through a 32-run full factorial experimental design, ERB was encapsulated within liposomal formulations, which were then optimized (ERB Lipo). The optimized batch was subsequently coated with chitosan to produce CS-ERB Lipo, which was then subjected to detailed characterization. Each liposomal ERB formulation's size was under 200 nanometers, and the polydispersity index for each was below 0.4. Evidence for a stable formulation was found in the zeta potential data for ERB Lipo (up to -50 mV) and CS-ERB Lipo (up to +25 mV). Within a gel, freeze-dried liposomal formulations were examined for in-vitro release characteristics and chemotherapeutic properties. The CS-ERB Lipo gel exhibited sustained release, maintaining its effect for 36 hours or more; this was in notable contrast to the control formulation's release characteristics. In vitro cell viability assays indicated a powerful anti-cancer effect on the KB cell line. Live animal studies demonstrated a substantial pharmacological improvement in reducing tumor volume with ERB Lipo gel (4919%) and CS-ERB Lipo gel (5527%) in comparison to the use of plain ERB Gel (3888%) when applied locally. nano-microbiota interaction Histology demonstrated that formulation could reverse the dysplasia condition, transitioning it into hyperplasia. Oral cavity cancers, both pre-malignant and early-stage, show improvement when treated with locoregional therapy involving ERB Lipo gel and CS-ERB Lipo gel.
Immunotherapy for cancer is enhanced by a new method of delivering cancer cell membranes (CM), thus activating the immune system. Introducing melanoma CM locally into the skin effectively stimulates antigen-presenting cells, particularly dendritic cells, promoting immune activation. In the present study, the fabrication of fast-dissolving microneedles (MNs) was undertaken for the delivery of melanoma B16F10 CM. Poly(methyl vinyl ether-co-maleic acid) (PMVE-MA), along with hyaluronic acid (HA), were assessed for their efficacy in the creation of MNs. CM was incorporated into MNs using either a multi-step layering procedure applied to MNs or the micromolding technique. The CM loading process and its subsequent stabilization were bettered by the strategic addition of sugars (sucrose and trehalose) and the surfactant Poloxamer 188, respectively. Ex vivo experiments using porcine skin showed a very quick dissolution of PMVE-MA and HA, taking less than 30 seconds. In contrast to other materials, HA-MN demonstrated superior mechanical properties, resulting in an enhanced resistance to fracture when subjected to compression. A B16F10 melanoma CM-dissolving MN system was developed effectively, hinting at the possibility of future immunotherapy and melanoma treatment breakthroughs.
Various biosynthetic pathways in bacteria contribute to the production of extracellular polymeric substances. Extracellular polymeric substances, originating from bacilli, including exopolysaccharides (EPS) and poly-glutamic acid (-PGA), function as active ingredients and hydrogels, alongside diverse industrial applications. Despite the functional diversity and broad range of applications these extracellular polymeric substances offer, their production yields are low, and their cost is high. The intricate biosynthesis of extracellular polymeric substances in Bacillus remains a poorly understood process, lacking a detailed account of the interactions and regulations between various metabolic pathways. Consequently, a deeper comprehension of metabolic processes is essential for expanding the capabilities and boosting the output of extracellular polymeric substances. Programmed ribosomal frameshifting In Bacillus, this review meticulously summarizes the biosynthesis and metabolic mechanisms of extracellular polymeric substances, yielding a profound understanding of the relationships between EPS and -PGA production. This review presents a sharper picture of how Bacillus metabolism functions during the production of extracellular polymeric substances, ultimately promoting their implementation and market success.
In diverse sectors, from cleaning agents to textiles and paints, surfactants have consistently played a crucial role as a significant chemical. Due to surfactants' exceptional capacity to decrease the surface tension between liquid-liquid interfaces, like water and oil, this outcome occurs. In the contemporary society, the beneficial effects of petroleum-based surfactants in decreasing surface tension have overshadowed the harmful consequences (such as detrimental effects on human health and water quality). These damaging effects will result in substantial environmental damage and negative consequences for human well-being. Subsequently, the need to secure environmentally favorable substitutes like glycolipids is critical to reducing the influence of these synthetic surfactants. Glycolipids, biomolecules similar in properties to naturally synthesized cellular surfactants, exhibit amphiphilic characteristics, forming micelles from clustered glycolipid molecules. This action, akin to surfactant behavior, lowers surface tension between interacting surfaces. Recent advancements in bacterial cultivation for glycolipid production are the focus of this review paper, which also details current laboratory-scale applications, encompassing medical uses and bioremediation of waste.
