Oxidative stress is involved in the progression of aging and Alzheimer's disease. It is known that lutein is a carotenoid having antioxidant properties. The present research explores Lutein loaded chitosan nanoparticles for Suppressing Oxidative Stress in the treatment of Alzheimer's. The developed nanoparticles are administered through the nose to target brain via nose-to-brain pathway. For optimization of formulation a systematic QbD approach was used. The developed nanoparticles further characterized for Physicochemical parameters, Morphology, In-vitro drug releases, Ex-vivo diffusion, In-vitro Cell viability, cellular uptake, In-vitro BBB Permeation, antioxidant properties, In-vivo biodistribution, and stability study. The developed nanoparticles' surface morphology suggested homogeneously dispersed spherical nanoparticles having &lt; 200 nm size. The drug release study demonstrate the controlled release of lutein for more than 96 h while less than 50% lutein was released after 24 h in an <em>ex-vivo</em> diffusion study. The cell cytotoxicity assay confirms the nontoxicity of <span>l</span>-CNPs. The cellular uptake study shows enhanced internalization of <span>l</span>-CNPs through the caveolae-mediated endocytosis pathway.

The antioxidant assay shows significant ROS scavenging activity of <span>l</span>-CNPs. <em>In-vitro</em> BBB permeation demonstrates the efficient passage of <span>l</span>-CNPs through BBB compared to pure lutein. This was further supported by bio-distribution demonstrating the deposition of nanoparticles in the brain through nasal administration.

The method is low cost, simple, practically active, and suitable to determine the sample due to color changes which are accessed visually even at low concentrations of target analysis. Hence, different methods are applied for detecting and determining pesticides (insecticides) and phenolic compounds (bisphenol A). Moreover, researchers detected OCPs (Organochloride pesticides) in breast milk and adipose tissues, which may exhibit estrogenic, and antiestrogenic activities mostly associated with breast cancer. The common thing between two the analytes is nature because they both show endocrine-disrupting properties. Bisphenol A (phenolic compound) is commonly used in the high-volume production of monomers and plastics. Bisphenol A is used to manufacture polycarbonate plastics, used in food cans coating, baby formula bottles, milk containers, paints, etc. Pesticides and phenolic compounds identification methods can be sluggish and need extremely skilled workforces to function cultured instruments that are mostly too expensive, delicate, or immense to a position outside of a devoted laboratory facility. This review deals with the discriminatory and low-cost method for the colorimetric detection of pesticides and phenolic compounds (bisphenol A) with different bio-synthesized metals and metal-doped nanocomposites. Based on existing publications, using colorimetry with nanocomposites provides low detection limits and good reproducibility for the detection of pesticides and phenolic compounds in various samples such as food samples.

This infectious bacterium remains a formidable global health challenge, necessitating urgent attention and comprehensive strategies to combat its profound impact on public health. MTB is a finicky bacterium that manages to sneak into macrophages and fibroblasts to avoid being eliminated. Current first-line treatments allow the control of the spread of an active MTB, but are not capable of effectively controlling when MTB is in its latent phase and struggle against MTB resistant strains. Lipid-based nanoparticles have gained significant attention in the field of tuberculosis nanotechnology treatments, owing to their compelling logical underpinnings, remarkable merits, and acknowledged demerits. These nanoparticles offer a rational approach by harnessing the unique properties of lipids, such as biocompatibility and stability, to encapsulate and protect anti-tuberculosis drugs. Their inherent ability to actively target infected macrophages holds immense promise for precise drug delivery to the infection site, enhancing therapeutic efficacy. However, it is crucial to consider potential limitations, such as the restricted payload capacity due to their small size and challenges in achieving sustained drug release. Despite these challenges, lipid-based nanotechnology represents an exciting frontier for combating drug resistance and advancing tuberculosis treatment strategies, warranting further exploration and development in this field. In addition, we emphasize the characteristics of lipid-based nanoparticles with the ability to improve the administration, stability, and dosage of these molecules.

Under pathological conditions such as cancer, the release of exosomes enhances tremendously, which are either fused or internalized by the recipient cells to elicit specific biological responses.

However, a deterministic mathematical modelling could overcome these limitations. In this study, we develop a model, based on a system of two differential equations (accounting for nanoparticle (NP) degradation and then drug release from degraded NM), which enable us to estimate per capita rate constant α (#NP degraded/hr) and β (Drug Amount Released/NP), the net effect of the nanomedicine (NE factor ɣ= α.β) and the controlled release index (φ, ratio of drug release to NP degradation). The model analysis conducted with tenofovir loaded hyaluronidase sensitive NM clearly shows the α factor significantly increased with triggering stimuli due to its enzymatic action on its substrate (hyaluronic acid). However, the β factor remained relatively unchanged, due to intrinsic physicochemical properties of the drug as limiting factor. The application of the solutions of this model clearly enabled us to effectively screen among various nanoformulations and identified the best hyaluronidase-sensitive NM formulation, exhibiting the highest ratio (3.7-fold increase compared to no enzyme). The φ value confirmed the controlled release and stimuli sensitivity of the nanosystem. Moreover, the computed drug release rate (dM/dt) is consistent with other existing mathematical models (under valid assumption). The key advantages of this approach are i) relevancy to underlying physicochemical and biochemical process, ii) versatility and application to various NM kinetics, and iii) prediction of temporo-spatial distribution of the drug loaded NP that could potentially improve <em>in-vitro/in vivo</em> correlation study.
