Blood-Brain-Barrier (BBB) Targeting Nanoparticulate Drug Delivery Modules to Treat Cerebrovascular Disorders: Current State of the Art
Blood Brain Barrier (BBB) provides a protective shield for the human nervous system facilitating essential biochemical processes while also acting as a strong defense mechanism against pathogens and harmful substances including drugs. While this barrier protects the brain it makes it difficult to deliver therapeutics to treat cerebral diseases such as ischemia and acute arterial thrombosis both of which cause significant global mortality and morbidity. The urgent need for thrombolytic agents to treat cerebral ischemia emphasizes the importance of drugs that can efficiently penetrate the BBB. However conventional thrombolytics have limitations due to low BBB permeability. To overcome this barrier various nanoparticle-based targeting strategies have been developed. These nano-technological solutions provide advantages such as enhanced permeability decreased toxicity risks and increased bioavailability when compared to other drug delivery methods.
Phyto-Active Components Delivered through Lipid Nanodrug Carriers as a Promising Avenue for the Treatment of Alzheimer’s Disease: Their Present Status and Industrial Viability
Present years have witnessed an unprecedented growth of Alzheimer’s disease (AD) with limited scope for conventional therapeutics. Plant-derived active components (PACs) are being widely utilized as alternate compatible efficacious eco-friendly strategies to ameliorate therapeutic benefits in AD while minimizing toxic effects. However delivery of PACs in the regular dosage form often faces challenges due to low stability and bioavailability brain-specific delivery dose-related toxic effects etc. which can be subsided by experimentally fabricated lipid nanodrug carriers (LNCs). The objective of this study was to provide a comprehensive evidence-based review on recent progress in the PACs-loaded lipid nanocarriers (PLNs)-based therapeutic strategies for AD.
For the study implementation a systematic literature review was carried out from various scientific potential databases like Scopus Pubmed Web of Science etc. and relevant evidence-based pre-clinical research data was pooled to draw conclusive outcomes.
LNCs are treated as promising avenues to effectively deliver various PACs into the brain due to their high lipophilicity with ultra-micron size and tunable surface features which make them eligible to pass through the blood-brain barrier. Both passive and active targeting of PLNs has been explored to target AD by overcoming the off-target bio delivery problems.
The review provided updated preclinical study-based data on the potentialities of PLNs in overcoming AD. Simultaneously equal weightage was devoted to the issues faced beyond the laboratory in their successful technology transfer. The study would be beneficial in unveiling important insights into the implications of PLNs for their futuristic clinical applicability.

Niosomes: A Comprehensive Review of Their Potential as Drug Carriers
Nanomaterials for medication delivery have attracted interest owing to their potential for on-target delivery to infected areas while sparing healthy tissue. The aim of the current review was to explore the factors that make niosomes a superior drug delivery system compared to other methods. The study was conducted using the databases such as PubMed Elsevier Springer and others in order to set up the required research articles based on the keyword as niosomes. The articles that were relevant to the topic and in English were included in the study. Niosomes differ from liposomes because they are non-ionic spherical surfactants with advantages such as they are less poisonous less prohibitive to access non–toxic and comparatively much more stable. Niosomes range from 20-1000 nm; however they can be classified as nanoparticles or/and nanostructures. Another property attributed to niosomes is their ability to entrap and release both polar and non-polar active compounds with equal effectiveness. For a drug to work it needs to reach the right place in the body and attach to its target. This allows the drug to have its intended effect. Niosomes can best be described as a potential drug carrier system because well-formulated niosomes can target drugs to specific locations of the body without much harm. This approach minimises the effects that may arise from the drug interacting with other sites or getting into the systemic circulation in the wrong manner. Hence there is hope for the future advancement in drug delivery systems using niosomes distinguishing it from conventional techniques. The potential to encapsulate and deliver hydrophilic as well as lipophilic drugs and the capacity of target delivery make them suitable for a number of therapeutic uses. Therefore with advancement in the research more extensive applications of niosomes can be visualized in the formulation of advanced drug delivery systems with lesser side effects.

Novel Application of Alumina Nanoparticle-enriched Cutting Fluid for the Surface Integrity and Machining of 17-4PH Steel
Stainless steel 17-4 PH is said to be a challenging material to cut due to its limited thermal conductivity. Early tool failure and inadequate surface finishing were observed because excessive cutting temperatures have a negative impact on productivity when machining 17-4 PH steel.
Therefore the present study explored the viability of alumina-reinforced ricebran oil (Al2O3 (80 nm)) nanoparticles with ricebran oil and divyol oil as lubricants. A diverse volume fraction of alumina was mixed with 5 vol. % rice bran oil ordivyol oil. Subsequently twenty-seven turning operations were performed on the 17-4PH material in the optimal lubricating medium. When Al2O3 nanoparticles are added to rice bran oil there is an 18.22% improvement in surface roughness.
The particle volumetric range that the authors chose was 0.25 vol.% to 1.25 vol.% to achieve equilibrium between the benefits of higher heat conductivity and the reduced pumping power resulting from high viscosity. The machining values were statistically analyzed via analysis of variance. In addition response surface methodology (RSM) was employed to develop a mathematical equation linking the input and machining responses.
A comparison of the two analyzed fluid systems revealed that the cutting force (Fz) feed force (Fx) thrust force (Fy) and surface roughness (Ra) of the Al2O3 mixed Rice Bran Oil cutting fluid were considerably lower than those of the other methods (8.89% 4.659% 9.1416% and 18.22% respectively).

Experimental and Statistical Assessment of the Interaction of Ether and Naphthalene-based Superplasticizers with Concrete
The significant concerns surrounding the interaction between cement and superplasticizers have led to several challenges in the performance of concrete in real-world applications. This study investigates the interaction between different types of cement and superplasticizers and presents findings on their compatibility. Additionally various interactions between cement and superplasticizers are utilized to assess the strength and durability properties of concrete.
Three distinct types of superplasticizers were utilized: sulfonated naphthalene (SNF) polycarboxylic ether (PCE) and polymeric ether (PME) based superplasticizers in combination with Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). Multiple concrete mixes with varying addition times of these superplasticizers were prepared and evaluated for their fresh and hardened concrete characteristics including workability strength and sorptivity among others. Moreover statistical analyses concerning different combinations of superplasticizers and cement as well as varying addition times were conducted to assess their respective impacts on concrete qualities.
The findings of the hypothesis testing indicated a substantial correlation between the delayed addition time of PPC mixes and variables such as compressive strength and workability with correlation coefficients ranging from 0.95 to 0.98. Conversely the correlation between these variables and OPC mixes was not found to be entirely significant (r; 0.85-0.89).
The established relationship indicated an improvement in the properties of fresh concrete due to enhanced compatibility between different superplasticizers and cement potentially aiding in the selection of optimal superplasticizer-cement combinations and addition times for superplasticizers.
In the present study numerous interactions between cement and superplasticizer are utilized to assess the strength and durability characteristics of the concrete.
