Targeting Peroxisome Proliferator-Activated Receptor-ß/δ, Reactive Oxygen Species and Redox Signaling with Phytocompounds for Cancer Therapy.

Significance: Peroxisome proliferator-activated receptors (PPARs) have a moderately preserved amino-terminal domain, an extremely preserved DNA-binding domain, an integral hinge region, and a distinct ligand-binding domain that are frequently encountered with the other nuclear receptors. PPAR-ß/δ is among the three nuclear receptor superfamily members in the PPAR group. Recent Advances: Emerging studies provide an insight on natural compounds that have gained increasing attention as potential anticancer agents due to their ability to target multiple pathways involved in cancer development and progression. Critical Issues: Modulation of PPAR-ß/δ activity has been suggested as a potential therapeutic strategy for cancer management. This review focuses on the ability of bioactive phytocompounds to impact reactive oxygen species (ROS) and redox signaling by targeting PPAR-ß/δ for cancer therapy. The rise of ROS in cancer cells may play an important part in the initiation and progression of cancer. However, excessive levels of ROS stress can also be toxic to the cells and cancer cells with increased oxidative stress are likely to be more vulnerable to damage by further ROS insults induced by exogenous agents, such as phytocompounds and therapeutic agents. Therefore, redox modulation is a way to selectively kill cancer cells without causing significant toxicity to normal cells. However, use of antioxidants together with cancer drugs may risk the effect of treatment as both act through opposite mechanisms. Future Directions: It is advisable to employ more thorough and detailed methodologies to undertake mechanistic explorations of numerous phytocompounds. Moreover, conducting additional clinical studies is recommended to establish optimal dosages, efficacy, and the impact of different phytochemicals on PPAR-ß/δ.

Neuroprotective Potential of Hesperidin as Therapeutic Agent in the Treatment of Brain Disorders: Preclinical Evidence-based Review.

Neurodegenerative disorders (NDs) are progressive morbidities that represent a serious health issue in the aging world population. There is a contemporary upsurge in worldwide interest in the area of traditional remedies and phytomedicines are widely accepted by researchers due to their health-promoted effects and fewer side effects. Hesperidin, a flavanone glycoside present in the peels of citrus fruits, possesses various biological activities including anti-inflammatory and antioxidant actions. In various preclinical studies, hesperidin has provided significant protective actions in a variety of brain disorders such as Alzheimer's disease, epilepsy, Parkinson's disease, multiple sclerosis, depression, neuropathic pain, etc. as well as their underlying mechanisms. The findings indicate that the neuroprotective effects of hesperidin are mediated by modulating antioxidant defence activities and neural growth factors, diminishing apoptotic and neuro-inflammatory pathways. This review focuses on the potential role of hesperidin in managing and treating diverse brain disorders.

New Insights into Pharmaceutical Nanocrystals for the Improved Topical Delivery of Therapeutics in Various Skin Disorders.

Nanotechnology has provided nanostructure-based delivery of drugs, among which nanocrystals have been investigated and explored for feasible topical drug delivery. Nanocrystals are nano-sized colloidal carriers, considered pure solid particles with a maximum drug load and a very small amount of stabilizer. The size or mean diameter of the nanocrystals is less than 1 µm and has a crystalline character. Prominent synthesis methods include the utilization of microfluidic- driven platforms as well as the milling approach, which is both adaptable and adjustable. Nanocrystals have shown a high capacity for loading drugs, utilization of negligible amounts of excipients, greater chemical stability, lower toxic effects, and ease of scale-up, as well as manufacturing. They have gained interest as drug delivery platforms, and the significantly large surface area of the skin makes it a potential approach for topical therapeutic formulations for different skin disorders including fungal and bacterial infections, psoriasis, wound healing, and skin cancers, etc. This article explores the preparation techniques, applications, and recent patents of nanocrystals for treating various skin conditions.

Herbal Medicines - a Fruitful Approach to Periodic Illness Dysmenorrhoea: Evidence-based Review.

Dysmenorrhea (menstrual or periodic pain) is a discomfort that occurs during painful periods. It is the first and most prominent reason for female lower abdominal pain. Most adolescent girls consider it a curse due to the periodic occurrence of painful cramps and bleeding. The pathogenesis of painful periods is most likely because of increased prostanoids, notably prostaglandins, produced by the cyclooxygenase pathway (PGs). Misuse of synthetic medications leads to the development of medication resistance and deposits toxic residues in the body; thus, there is a critical need for safe and effective alternatives. In recent decades, herbal treatment approaches have found extensive applications in the treatment of various ailments. Herbal therapies are an alternate source, which include several bioactive chemicals, and recent improvements in our understanding of the value of herbal therapy methods have caused a sharp rise in their production. The main focus of this review was to study herbal treatment options; the recent studies conducted on herbal therapies and various experimental investigations on dysmenorrhea and herbal therapy methods have been studied, and randomized controlled trials and animal models have been discussed describing the anti-inflammatory properties of some potential herbal medicines that can be used as treatment options for dysmenorrhoea. This review aimed to present herbal treatments that can be used as alternative traditional synthetic medications and oral hormonal contraceptives in the treatment of painful menstruation.

Epidemiology, Risk Factors, Diagnosis and Treatment of Mucormycosis (Black Fungus): A Review.

The COVID-19 pandemic has shown an adverse effect worldwide, but in India, it has been observed during the second wave that people who recovered from COVID-19 infection developed a secondary infection because it grows in tandem with COVID-19 treatment. Meanwhile, news of a new deadly fungus has surfaced known as Mucormycosis (Black fungus). Mucormycosis is a fungal infection that invades the blood vessels and is caused by Mucormycetes, a group of fungi. Due to the post-pandemic effect of COVID-19 many fungal and bacterial diseases have affected the population. The reason behind the frequent development of opportunistic infections like mucormycosis is the use of steroids, oxygen masks, and antibiotics throughout the treatment of critically and severely ill patients with COVID-19. Inhaling filamentous fungi from the natural environment and a lack of supportive care units can be a risk factor for mucormycosis. It is usually found in people who are immunocompromised. Mucormycosis is more common in people with HIV/AIDS, COVID-19, congenital bone marrow disease, viral diseases, malignancies, severe burns, and irregularly or untreated and treated diabetes. This review emphasizes triggers that may precipitate mucormycosis related to corticosteroids, recent epidemiology, and incidence of mucormycosis. The infection was diagnosed and identified using a variety of cutting-edge medical techniques, including clinical diagnosis, histopathology, and serology. Many treatment methods, such as antifungal medications and therapies, have also been successfully used. The mortality rate, however, remains high due to an aggressive surgical excision or debridement and lack of early diagnosis.
