Even though most people with breast cancer are 65 years old. Women of any age can get this disease. 1 It is thought that 0.0001% of women under 20 will get breast cancer, 0.0014% of women 20 to 24 years old, 0.0081% of women 25 to 29 years old, and 0.0248% of women 30 to 34 years old. Although breast cancer mostly affects women, about 1% of all cases are found in men. Breast cancer is still one of the top reasons women die worldwide. The disease is linked to how well they fight off cancer treatments. 2 It is thought that 90% of all treatment failures are due to drug resistance, which can be acquired or built-in. Only 26% of people with metastatic breast cancer in the US will still be alive after 5 years 3. Drug resistance is thought to be caused by several biological factors, such as changes in genetics, bypass mechanisms, altered effectors in DNA repair, acquired resistance that doesn't depend on a specific route, changes in pH, and increased activity of efflux pumps in cell membranes 4. The cancer gets bigger, physical hurdles make it harder for drugs to move around and reach the levels needed for lethal concentrations in the areas of interest. A thick extracellular matrix, interstitial hypertension, and hostile conditions like ABSTRACT Breast cancer continues to be a prevalent and highly lethal cancer affecting women globally. Despite significant advancements in early detection and the development of specific therapeutic approaches, the issue of medication resistance remains a prominent challenge in managing this intricate ailment. The study offers a comprehensive analysis of the mechanisms behind the development of treatment resistance in breast cancer cells. The objective of this study is to provide a comprehensive understanding of the molecular and cellular mechanisms behind the occurrence of therapeutic ineffectiveness. This study elucidates several molecular subtypes of breast cancer and their pharmacological responses. The significance of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) in the development of treatment resistance is emphasized. Additional research on the intricacies of innate and acquired drug resistance mechanisms, including genetic modifications, tumor heterogeneity, and the presence of cancer stem cells, has shed light on the multifaceted nature of drug resistance and its dynamic evolution throughout treatment. Furthermore, this study provides a comprehensive analysis of the impact of microenvironmental variables, including hypoxia, immune evasion, and tumor-stroma connections, on the development of drug resistance. The investigation of the interplay between tumor suppressors and oncogenes in the emergence of drug resistance is now underway, yielding valuable insights into prospective targets for therapeutic intervention. Additionally, this study examines the limitations associated with conventional chemotherapy, endocrine therapies, and targeted medicines, while elucidating the mechanisms underlying treatment resistance and proposing potential strategies to overcome it. Emerging therapies like immunotherapies, epigenetic modulators, and new drug delivery methods are looked at to see if they have the potential to get around mechanisms of resistance and improve patient outcomes. This review aims to give clinicians, researchers, and other healthcare workers a full picture of breast cancer's complex drug resistance mechanisms. By figuring out the molecular complexities and signaling pathways that lead to treatment resistance, we aim to speed up the development of new therapeutic approaches and personalized interventions. This will bring us closer to the long-awaited goal of beating drug resistance and making breast cancer a manageable, treatable condition.

Methods: The ATN-CE-SD was prepared using the solvent evaporation technique. The pure ATN, physical mixture, CE carrier, and optimized ATN-CE-SD was physicochemically characterized using Scanning electron microscopy, Fourier transforms infrared spectroscopy, differential scanning calorimetry, powder x-ray diffractometry, solubility, and in vitro dissolution was used to evaluate solid dispersions. Results: Physical and chemical analysis showed that ATN-CE-SD formed via the involvement of weak intermolecular forces of attraction between CE carrier and ATN. The prepared solid dispersion showed the drug content around ~ 96.94 % w/w, indicating that the solvent evaporation method improved the encapsulation of ATN and, thus, enhanced its drug content. Compared to pure ATN (~ 0.11 mg/ml), ATN-CE-SD (1:2) significantly increased the aqueous solubility by around ~ 25-fold (~ 2.78 mg/ml), indicating solid dispersion improves the solubility of ATN. ATN-CE-SD enhanced the rate of dissolution of ATV (~ 65 %) compared to pure ATN (~ 25 %) and PM (~ 34 %). Likewise, ATN-CE-SD (1:2) improved the rate and extent of ATN (~ 60 %) across the biological membrane compared to pure ATN (~ 22 %) and PM (~ 32 %). The ATN-CE-SD (1:2) improved the dissolution efficiency by around ~ (57.31%) compared to pure ATN (~ 7.02%) and PM (~ 20.43%). According to the study, co-processed excipients could serve as a promising solid dispersion carrier and improve ATN's water solubility, permeability, and dissolution rate. Conclusion: Based on the results, it is possible to use synthetic solid dispersion carriers as alternatives to improve the low water solubility and permeability of ATN.

Cosmetic is a translation of the word "kosm tikos" in Greek, which signifies having the ability to plan and decorate. Cosmetics are a group of cosmetics and health products utilized to improve and may alter someone's appearance and additionally care for the body and face parts. In almost every civilization on earth, cosmetics have such a tradition that spans more than 7,000 years. It is clear that the beauty business has done an amazing job at influencing our minds' perceptions. India now counts among the developing nations that has the fastest-growing cosmetic industries with each passing year. The Indian cosmetics industry registered revenues of more than 350 billion rupees in 2009, despite the global economic downturn. Soaps, creams, and sunscreens are a few of the common cosmetics. Despite the fact that a sizable portion of the world's population views cosmetics as a boon, cosmetics do carry some danger and toxicity. Some of the most recent trends in cosmetics include releases based on biological stimuli, Circular Economy, and in vitro modeling for cosmetics. The category of cosmetics known as "hypoallergenic" can be characterized as those that, when compared to other cosmetic formulas, tend to cause fewer allergic reactions. FDA was affirmed by the court despite claims from the two companies that it lacked the authority to impose the regulation. Subsequently, the United States Court of Appeals ruled that cosmetic businesses may continue to use the phrase "hypoallergenic" on their labels. Those with sensitive skin and hair may have fewer severe allergic reactions thanks to the labeling process. It is clear that cosmetics play a significant part in daily life and are utilized by people of all sexes, resulting in a rise in cosmetic usage.

Methods: The niosome carriers were formulated using non-ionic surfactants and cholesterol ratio of 1:1. The effects of non-ionic surfactant and cholesterol on the average particle size and percent entrapment efficiency were studied. Optimization of the formulation was performed by factorial design using Design expert software 11.0. Results: Based on the solutions provided by the design expert software, the formulation resulted in the particle size of 490 nm and 92.4% EE as compared to the predicted values of 491.02nm for particle size and 90% EE. The optimized niosome carriers appeared as multilamellar vesicles, as evident by a scanning electron microscopy study. Anticonvulsant activity of the niosomal dispersion was determined by Pentylenetetrazol (PTZ) induced convulsions in mice. Pregabalin-loaded niosomal dispersion displayed a sustained and moderate anticonvulsant effect upto 24 h. Conclusion: Therefore, the present study revealed the possibility of using non-ionic surfactant niosomes as carrier systems for prolonged release of pregabalin.

Cosmetic is a translation of the word "kosm tikos" in Greek, which signifies having the ability to plan and decorate. Cosmetics are a group of cosmetics and health products utilized to improve and may alter someone's appearance and additionally care for the body and face parts. In almost every civilization on earth, cosmetics have such a tradition that spans more than 7,000 years. It is clear that the beauty business has done an amazing job at influencing our minds' perceptions. India now counts among the developing nations that has the fastest-growing cosmetic industries with each passing year. The Indian cosmetics industry registered revenues of more than 350 billion rupees in 2009, despite the global economic downturn. Soaps, creams, and sunscreens are a few of the common cosmetics. Despite the fact that a sizable portion of the world's population views cosmetics as a boon, cosmetics do carry some danger and toxicity. Some of the most recent trends in cosmetics include releases based on biological stimuli, Circular Economy, and in vitro modeling for cosmetics. The category of cosmetics known as "hypoallergenic" can be characterized as those that, when compared to other cosmetic formulas, tend to cause fewer allergic reactions. FDA was affirmed by the court despite claims from the two companies that it lacked the authority to impose the regulation. Subsequently, the United States Court of Appeals ruled that cosmetic businesses may continue to use the phrase "hypoallergenic" on their labels. Those with sensitive skin and hair may have fewer severe allergic reactions thanks to the labeling process. It is clear that cosmetics play a significant part in daily life and are utilized by people of all sexes, resulting in a rise in cosmetic usage.

Because of the difficulties associated with the oral administration of DOX, there is not yet a commercially available oral formulation of DOX. Nanocarrier system was manufactured utilizing poly (lactic-co-glycolic acid) (PLGA) and treated with chitosan to provide a surface coated. Nanoparticles (NPs) were created using a modified emulsification solvent diffusion (nanoprecipitation) method by electrostatic conjugation of chitosan to modify nanoparticle surfaces. The model was built using a Box-Behnken design with three independent components: X1 (PLGA), X2 (poloxamer 188), and X3 (chitosan concentration). The optimized chitosan-PLGA NPs had a mean particle size of 153.6 nm and a positive zeta potential of 21.51 mV. More than 85% DOX permeated through the everted gut by DOX-loaded chitosan-NPs as compared to NPs prepared with PLGA alone. Chitosan ...
