RESUMO

Every year, the World Health Organization reports 500,000 new cases of drug-resistant tuberculosis (TB), which poses a serious global danger. The increased number of XDR-TB and MDR-TB cases reported worldwide necessitates the use of new therapeutic approaches. The main issues with the antitubercular medications now in use for the treatment of multidrug-resistant tuberculosis are their poor side effect profile, reduced efficacy, and antimicrobial resistance. One possible remedy for these problems is bedaquiline. The need for better treatment strategies is highlighted by the strong minimum inhibitory concentrations that bedaquiline (BDQ), a novel anti-TB medicine, exhibits against both drug-resistant and drug-susceptible TB. Bedaquiline may be able to help with these problems. Bedaquiline is a medication that is first in its class and has a distinct and particular mode of action. Bedaquiline is an ATP synthase inhibitor that is specifically directed against Mycobacterium tuberculosis and some nontuberculous mycobacteria. It is metabolized by CYP3A4. Bedaquiline preclinical investigations revealed intralesional drug biodistribution. The precise intralesional and multi-compartment pharmacokinetics of bedaquiline were obtained using PET bioimaging and high-resolution autoradiography investigations. Reduced CFU counts were observed in another investigation after a 12-week course of therapy. Meta-analyses and systematic reviews of phase II trials on bedaquiline's efficacy in treating drug-resistant tuberculosis in patients reported higher rates of cure, better culture conversion, and lower death rates when taken in conjunction with a background regimen. Here is a thorough medication profile for bedaquiline to aid medical professionals in treating individuals with tuberculosis.

RESUMO

Curcumin is a naturally occurring polyphenolic compound extracted from the rhizomes of Curcuma longa, commonly known as turmeric. It has been used for centuries in traditional medicine and is gaining increasing attention in modern medicine owing to its potential therapeutic benefits. Psoriasis is a chronic inflammatory disease characterized by red scaly patches on the skin. Curcumin has been found to be effective in treating psoriasis by inhibiting the activity of various enzymes and proteins involved in the inflammation and proliferation of psoriatic skin cells. Nanogel preparation of curcumin has been found to be a promising approach for the delivery of compounds to treat psoriasis. Nanogels are composed of biocompatible and biodegradable crosslinked hydrogels. The nanogel formulation of curcumin increases its solubility, stability, and bioavailability, indicating that a lower dose is needed to achieve the same therapeutic effect. This review article suggests that the nanogel preparation of curcumin can be a better alternative for psoriasis treatment as it increases the bioavailability and stability of curcumin and also reduces the required dosage. This study suggests that curcumin nanogel preparations are promising alternatives to traditional psoriasis treatments and could potentially be used as a more effective and safe treatment option. This article highlights the need for further research to fully understand the potential of curcumin nanogel preparations for psoriasis treatment in humans.

RESUMO

From ancient times fish has always been considered as an important human food item. The purpose of this article is to introduce the perception that beside consumption, fish can also be used as a raw material for the industrial production of different products. In this article such 19 products have been described. Among them, the conventional fish products described herein include isinglass, pituitary gland, chitin, chitosan, pearl essence, fish skin leather, fish protein hydrolysates and concentrates, fish meal and scrap, fish oil, collagen, gelatin, glue, fish silage, pet food and wet feed from fish, fish fertilizer and compost. These products have important applications in aquaculture, agriculture, food, cosmetics and other industries. Different non-conventional hi-tech fish products has been reported such as novel antimicrobial proteins from skin mucus, enzymes, insulin, protamine, blood proteins, salcotonin, antifreeze proteins, hydroxyapatite, burn treatment bandage, albumins, fishbone calcium powder, biochar, biopolymer, bioplastics, fish industry derived rinse water recovery. These products have many significant applications in chemical, biomedical and pharmaceutical industries. Economical, logistic, environmental and technological considerations from fish waste valorization perspectives has also been presented to evaluate feasibility of industrial-scale production of these products.

RESUMO

Diabetic neuropathy (DN) is a common and debilitating complication of diabetes mellitus that affects the peripheral nerves and causes pain, numbness, and impaired function. The pathogenesis of DN involves multiple molecular mechanisms, such as oxidative stress, inflammation, and pathways of advanced glycation end products, polyol, hexosamine, and protein kinase C. Phytochemicals are natural compounds derived from plants that have various biological activities and therapeutic potential. Flavonoids, terpenes, alkaloids, stilbenes, and tannins are some of the phytochemicals that have been identified as having protective potential for diabetic neuropathy. These compounds can modulate various cellular pathways involved in the development and progression of neuropathy, including reducing oxidative stress and inflammation and promoting nerve growth and repair. In this review, the current evidence on the effects of phytochemicals on DN by focusing on five major classes, flavonoids, terpenes, alkaloids, stilbenes, and tannins, are summarized. This compilation also discusses the possible molecular targets of numerous pathways of DN that these phytochemicals modulate. These phytochemicals may offer a promising alternative or complementary approach to conventional drugs for DN management by modulating multiple pathological pathways and restoring nerve function.

RESUMO

Neurodegeneration is characterized as the continuous functional and structural loss of neurons, resulting in various clinical and pathological manifestations and loss of functional anatomy. Medicinal plants have been oppressed from ancient years and are highly considered throughout the world as a rich source of therapeutic means for the prevention, treatment of various ailments. Plant-derived medicinal products are becoming popular in India and other nations. Further herbal therapies shows good impact on chronic long term illnesses including degenerative conditions of neurons and brain. The use of herbal medicines continues to expand rapidly across the world. The active phytochemical constituents of individual plants are sometimes insufficient to achieve the desirable therapeutic effects. Combining the multiple herbs in a particular ratio (polyherbalism) will give a better therapeutic effect and reduce toxicity. Herbal-based nanosystems are also being studied as a way to enhance the delivery and bioavailability of phytochemical compounds for the treatment of neurodegenerative diseases. This review mainly focuses on the importance of the herbal medicines, polyherbalism and herbal-based nanosystems and its clinical significance for neurodegenerative diseases.

RESUMO

BACKGROUND: Around 1.5 billion people in the world were affected by complex neurological disorders and the figure is increasing alarmingly due to unsatisfactory clinical outcomes. To date, no conventional formulation is able to show a promising effect on the control or prevention of neurodegeneration. However, Nano delivery tools have shown better penetration and profound action on the targeted area of the brain. METHODS: Although existing Nano therapeutic approaches are abundant but would not reach the clinic due to their improper bioavailability, BBB restricts its entry and causes improper biodistribution, so it's a challenge to use certain bioactive as a potential therapy in neurodegenerative disorders. Hybrid nanocarriers are nano-vesicular transported systems, which could be utilized as carriers for the delivery of both hydrophilic and hydrophobic compounds. Available patents on nanodelivery for therapeutic approach will also include in this review. RESULTS: Hybrid Nano delivery system may provide good stability to polar and nonpolar compounds and improve their stability. CONCLUSION: This manuscript updates the available findings on the Nano vesicular system to deliver drugs for neurodegenerative disorders.
