    Exploring the Role of Natural Bioactive Molecules in Genitourinary Cancers
    (Springer, 2023-10-16) Islam, Fahadul; Nath, Nikhil; Zehravi, Mehrukh; Khan, Jishan; Jashim, Sumiya Ben‑Ta; Charde, Manoj Shrawan; Chakole, Rita Dadarao; Kumar, Praveen; Babu, A. Kishore; Nainu, Firzan; Khan, Sharuk L.; Rab, Safia Obaidur; Emran, Talha Bin; Wilairatana, Polrat
    The primary approaches to treat cancerous diseases include drug treatment, surgical procedures, biotherapy, and radiation therapy. Chemotherapy has been the primary treatment for cancer for a long time, but its main drawback is that it kills cancerous cells along with healthy ones, leading to deadly adverse health effects. However, genitourinary cancer has become a concern in recent years as it is more common in middle-aged people. So, researchers are trying to find possible therapeutic options from natural small molecules due to the many drawbacks associated with chemotherapy and other radiation-based therapies. Plenty of research was conducted regarding genitourinary cancer to determine the promising role of natural small molecules. So, this review focused on natural small molecules along with their potential therapeutic targets in the case of genitourinary cancers such as prostate cancer, renal cancer, bladder cancer, testicular cancer, and so on. Also, this review states some ongoing or completed clinical evidence in this regard.

    Mucormycosis in the COVID-19 Environment
    (Daffodil International University, 2022-07-18) Sharma, Rohit; Kumar, Praveen; Rauf, Abdur; Chaudhary, Ashun; Prajapati, Pradeep Kumar; Emran, Talha Bin; Gonc, Clara Mariana; Lima, Clara Mariana Goncalves; Conte-Junior, Carlos Adam
    The second wave of coronavirus disease 2019 (COVID-19) caused severe infections with high mortality. An increase in the cases of COVID-19-associated mucormycosis (CAM) was reported predominantly in India. Commonly present in immunocompromised individuals, mucormycosis is often a life-threatening condition. Confounding factors and molecular mechanisms associated with CAM are still not well understood, and there is a need for careful research in this direction. In this review, a brief account of the diagnosis, management, and advancement in drug discovery for mucormycosis has been provided. Here, we summarize major factors that dictate the occurrence of mucormycosis in COVID-19 patients through the analysis of published literature and case reports. Major predisposing factors to mucormycosis appear to be uncontrolled diabetes, steroid therapy, and certain cancers. At the molecular level, increased levels of iron in COVID-19 might contribute to mucormycosis. We have also discussed the potential role and regulation of iron metabolism in COVID-19 patients in establishing fungal growth. Other factors including diabetes prevalence and fungal spore burden in India as contributing factors have also been discussed.
