The human immune system plays a pivotal role in protecting the body against pathogens, maintaining homeostasis, and preventing disease. Immunomodulation, the process of regulating immune responses, is crucial for optimal health. In recent years, there has been growing interest in natural remedies for immune system modulation, driven by the recognition of their potential efficacy and safety profiles. This project aims to investigate the immunomodulatory effects of drumstick leaves tablets, derived from Moringa oleifera, a plant known for its rich nutritional and medicinal properties. The study will explore the potential of drumstick leaves tablets to modulate immune responses through in vitro and in vivo experiments. Through comprehensive analysis of the immunomodulatory properties of drumstick leaves tablets, this project aims to contribute to our understanding of natural remedies for immune system modulation. The findings could have significant implications for the development of novel therapeutic interventions aimed at enhancing immune function and improving human health.

Objective: Raloxifene hydrochloride (RLX) is used extensively in the treatment of osteoporosis, only 2% of RLX's bioavailability remains after a significant first pass metabolism. Besides coming from BCS class II, RLX is not very soluble in water. Thus, the goal of the current study was to improve RLX solubility by creating an inclusion complex using β cyclodextrin (β-CD) as a carrier and solid dispersion with Poloxamer 407.

Methods: Inclusion complex and solid dispersion were made using a variety of techniques, including kneading, co-precipitation, and physical mixing and solid dispersion using different drug to carrier ratios (1:1, 1:2 and 1:3).

Results: Inclusion complex made using the co-precipitation method had shown 9-fold improvements in water solubility when compared with plain RLX. In order to assess the optimized complex's compatibility, thermal analysis, and crystallinity, X-ray diffraction, differential scanning calorimetry, and Fourier transform infrared spectroscopy were used. The XRD and DSC study's results indicated that RLX changed from a crystalline to an amorphous state. IC-6 exhibits effective water solubility based on the outcome. However, upon comparison of the two techniques, the β-CD complexation method shown an impressive rise in drug solubility when compared to solid dispersion.

Background: Medicinal plants have curative properties due to the presence of various complex chemical substances of different compositions, which are found as secondary plant metabolites in one or more parts of the plants. Moringa oleifera from Moringaceae and Beta vulgaris root are, native to India, grows in the tropical and subtropical regions of the world. It is commonly known as 'drumstick tree' or 'horseradish tree' or 'miracle tree'. Incorporation of more herbal powder leads to much complexity. Above plants were chosen for their utmost nutritional values.

Results: Herbal tablet and granules were prepared and evaluated further for various Physico-chemical parameters as a nutritional supplement. Promising results indicate that prepared formulations have potential as supplements.

Conclusions: Present communication mainly focused on estimation of marker components by Reverse Phase-High Performance Liquid Chromatography. It showed the presence of enough number of secondary metabolites and minerals which can be easily consumed by all age groups.

In the United States, cancer is one of the major causes of death. In 2010 alone, over 1.5 million fresh instances were recorded and over 0.5 billion died. After the completion of human genome sequence, significant progress in characterizing human epigenomes, proteomes and metabolomes has been made; a stronger knowledge of pharmacogenomics has been established and the capacity for individual personalization of health care has grown considerably. Personalized medicine has recently been primarily used to systematically select or optimize the prevention and therapeutic care of the patient through genetic or other data about the particular patient. Molecular profiling in healthy samples and cancer patients can allow for more personalized medications than is currently available. Patient protein, genetic and metabolic information may be used for adapting medical attention to the needs of that individual. The development of complementary diagnostics is a key attribute of this medicinal model. Molecular tests measuring the level of proteins, genes or specific mutations are used to provide a specific treatment for a particular individual by stratify the status of a disease, selecting the right drugs and tailoring dosages to the particular needs of the patient. These methods are also available for assessing risk factors for a patient for a number of conditions and for tailoring individual preventive therapies. Recent advances of personalized cancer medicine, challenges and futures perspectives are discussed.

Silver nanoparticles (AgNPs) have garnered significant attention in recent years due to their unique properties and diverse applications across various industries. This review provides an overview of the synthesis methods, characterization techniques, applications, regulatory guidelines, and challenges associated with AgNPs.

AgNPs find applications in biomedical, environmental, and consumer product sectors, including wound dressings, water purification filters, cosmetics, and medical devices, owing to their antimicrobial, catalytic, and optical properties. Regulatory guidelines play a crucial role in ensuring the safe and responsible use of AgNPs, addressing concerns related to biocompatibility, toxicity, and environmental impact. However, challenges remain in standardization, scalability, and long-term safety assessment of AgNP-based products. Future research efforts should focus on optimizing synthesis methods, enhancing characterization techniques, and addressing regulatory gaps to unlock the full potential of AgNPs while ensuring their safety and sustainability. Overall, AgNPs offer promising opportunities for addressing global challenges and driving technological innovation across diverse sectors.

A peptic ulcer is a lesion (sore) on the stomach lining, or duodenum. Peptic ulcers are probably a twentieth-century condition. The ulcer disease continues to be a significant source of worldwide morbidity and mortality. The Gastrointestinal ulcers and duodenal ulcers are considered the two most extreme types of peptic ulcers. Peptic ulcers are found to be caused by an excess of violent factors including Hydrochloric acid (HCL) pepsin, refluxed bile leukotrienes (LT), reactive oxygen species (ROS) and protective factors, these include mucus-bicarbonate barrier functions, prostaglandins (PGs), mucosal blood flow, cell regeneration and migration, non-enzymatic and enzymatic and certain growth factors. The primary cause of peptic ulcer disease is pylori infection and the use of NSAIDs. This review article underscores the importance of a multidisciplinary approach in the management of ulcers to improve patient outcomes and quality of life.

Mucoadhesive polymers are a new and exciting development in drug delivery systems that have the potential to significantly increase therapeutic efficacy. These polymers stick to mucosal surfaces, increasing the amount of time that medications stay at the site of absorption and improving their bioavailability. These mechanisms include longer contact times with the mucosal surface, better drug solubility, and defence against enzymatic degradation of pharmaceuticals. Mucoadhesive polymers also provide a number of benefits over traditional drug delivery methods, including less frequent dosage, better patient compliance, and fewer adverse effects. Due to their adaptability, Mucoadhesive polymers may be used in the rectal, vaginal, ophthalmic, nasal, and oral routes of drug delivery. Mucoadhesive polymers have advantages now, but they also have potential for the future of medication delivery. Mucoadhesion offers excellent possibilities for the delivery of a range of substances through the nasal, vaginal, buccal, and ocular routes of administration. Furthermore, mucoadhesion facilitates the achievement of an extended local or systemic pharmacological effect. In this study, we covered the mechanisms behind mucoadhesion, possible uses for Mucoadhesive polymers in drug administration, and techniques for assessing Mucoadhesive drug delivery systems. The goal of current research is to create innovative Mucoadhesive polymers that have better biodegradability, biocompatibility, and adhesive qualities. Moreover, it is anticipated that the effectiveness of Mucoadhesive polymers would be increased when combined with other cutting-edge drug delivery technologies, such as micro particles and nanoparticles.
