Nivolumab-associated IgA Nephropathy in a Child With Malignant Melanoma.

Immune checkpoint inhibitors are humanized antibodies that inhibit downregulatory receptors on T cells, enhancing the antitumor activity of these cells. However, they have been associated with a wide range of systemic immune-related adverse events, including renal toxicities, among others. Most renal immune-related adverse events are acute interstitial nephritis causing acute kidney injury.

molecular interactions among the secondary metabolites of spp. and colorectal cancer targets.

spp. secrete more than thirty different bioactive chemicals which have already been used in cancer treatment research since they play a pivotal role in cancer metabolism. Colorectal cancer is one of the most common cancer types, thus using novel and effective chemicals for colorectal cancer treatment is crucial.

An Efficient and Quick Analytical Method for the Quantification of an Algal Alkaloid Caulerpin Showed In-Vitro Anticancer Activity against Colorectal Cancer.

Biological invasion is the successful spread and establishment of a species in a novel environment that adversely affects the biodiversity, ecology, and economy. Both invasive and non-invasive species of the genus secrete more than thirty different secondary metabolites. Caulerpin is one of the most common secondary metabolites in genus .

Comparison of Cytotoxic and Ototoxic Effects of Lipoplatin and Cisplatin in Neuroblastoma In Vivo Tumor Model.

Background: This study aimed to compare the cytotoxic, cytostatic, and ototoxic effects of lipoplatin compared to cisplatin application in the subcutaneous xenograft nude mouse neuroblastoma tumor model.
