The first detection of Pneumocystis jirovecii in asthmatic patients post-COVID-19 in Jordan.

Pneumocystis jirovecii pneumonia (PCP), caused by fungal species named Pneumocystis jirovecii, is a frequent opportunistic infection in those with human immunodeficiency virus (HIV) infection. However, PCP has been documented in immunocompetent patients. This study aims to determine if P.

Targeting Drug Chemo-Resistance in Cancer Using Natural Products.

Cancer is one of the leading causes of death globally. The development of drug resistance is the main contributor to cancer-related mortality. Cancer cells exploit multiple mechanisms to reduce the therapeutic effects of anticancer drugs, thereby causing chemotherapy failure.

Melatonin in Cancer Treatment: Current Knowledge and Future Opportunities.

Melatonin is a pleotropic molecule with numerous biological activities. Epidemiological and experimental studies have documented that melatonin could inhibit different types of cancer in vitro and in vivo. Results showed the involvement of melatonin in different anticancer mechanisms including apoptosis induction, cell proliferation inhibition, reduction in tumor growth and metastases, reduction in the side effects associated with chemotherapy and radiotherapy, decreasing drug resistance in cancer therapy, and augmentation of the therapeutic effects of conventional anticancer therapies.

Resveratrol and Tumor Microenvironment: Mechanistic Basis and Therapeutic Targets.

Resveratrol (3,4',5 trihydroxystilbene) is a naturally occurring non-flavonoid polyphenol. It has various pharmacological effects including antioxidant, anti-diabetic, anti-inflammatory and anti-cancer. Many studies have given special attention to different aspects of resveratrol anti-cancer properties and proved its high efficiency in targeting multiple cancer hallmarks.
