The detection of pharmaceuticals in water and wastewater has triggered human and ecological health concerns. As highly toxic compounds, chemotherapy agents (CAs), such as the cyclophosphamide (CYP) and ifosfamide (IFO) structural isomers, represent a unique threat. This research elucidated the fate of CYP and IFO during ozonation and advanced oxidation by hydroxyl radicals (HO• ). Novel semi-batch reactors were used to determine the second-order rate constants for CYP and IFO with O3 and HO• . These reactors provided independent control of the oxidant exposure through continuous and constant aqueous ozone and peroxone (O3 -H2 O2 ) addition...

Outcomes with follicular lymphoma (FL) have improved in the modern era and median survival is now beyond 15 years. Therapeutic decisions need to consider this increased survival as well as recent clinical trial data and emerging treatments. In this context, we present here current approaches to front-line management of FL in Australia. Treatment choices depend on the disease stage, tumour burden, the patient's age, symptoms, comorbidities and preferences. Only about 10-15% of patients with FL are diagnosed with early stage disease...

The waste of commonly used medicines is known to contaminate freshwater ecosystems. Pharmaceuticals can be toxic, mutagenic, or modifying to freshwater organisms even at low concentrations if consider their permanent presence in the environment. Chemotherapeutics used to treat cancer, and in particular alkylating agents, contribute significantly to this form of pollution, the latter introducing cytotoxic and/or mutagenic lesions to the DNA and RNA of organisms which can be disruptive to their cells. The aim of the present study was to investigate the influence of the alkylating anticancer agent cyclophosphamide (CP) on Daphnia magna clones...

The presence of anticancer drugs in the environment raises a major concern due to their potentially negative impact on living organisms, as they cause, inter alia, teratogenic, mutagenic, carcinogenic effects on growing cells. The main source of these pharmaceuticals in the environment is the ineffectively treated wastewaters, hence the efficient methods for their removal are required. In this study, we have evaluated for the first time the applicability of different Multi-Walled Carbon Nanotubes (MWCNTs) as alternative adsorbents for the removal of three popular anticancer drugs from water matrices, which are detected in waste/hospital waters at the concentrations even up to μg L-1 : cyclophosphamide (CP), ifosfamide (IF) and 5-fluorouracil (5-FU)...

Pharmaceuticals are environmental micropollutants that pose an emerging challenge because they are poorly eliminated in conventional wastewater treatment plants. Over the last decade, many attempts have been made to solve this problem, and wastewater fungal treatment is a promising alternative. In this study, six different ligninolytic fungi (Trametes versicolor, Ganoderma lucidum, Irpex lacteus, Stropharia rugosoannulata, Gymnopilus luteofolius and Agrocybe erebia) were studied as bioremediation candidates for the removal and degradation of six recalcitrant pharmaceutical micropollutants: Carbamazepine (CBZ), Venlafaxine (VFX), Iopromide (IPD), Diclofenac (DCF), Cyclophosphamide (CFD) and Ifosfamide (IFD)...

A variant of dielectric-barrier discharge named surface desorption dielectric-barrier discharge ionization (SDDBDI) mass spectrometry was developed for high-efficiency ion transmission and high spatial resolution imaging. In SDDBDI, a tungsten nanotip and the inlet of the mass spectrometer are used as electrodes, and a piece of coverslip is used as a sample plate as well as an insulating dielectric barrier, which simplifies the configuration of instrument and thus the operation. Different from volume dielectric-barrier discharge (VDBD), the microdischarges are generated on the surface at SDDBDI, and therefore the plasma density is extremely high...

Drug interactions may dictate the failure or success of a treatment. Patients undergoing hematopoietic stem cell transplantation (HSCT) are exposed to various types of drugs, and understanding how these drugs interact is of the utmost importance. The pharmacokinetics of busulfan, melphalan, and cyclophosphamide, drugs commonly used for HSCT, are known to be affected by a variety of other drugs with differing molecular structures. We hypothesized that these structurally unrelated drugs affect the transport of DNA-alkylating agents...

The binding of the p53 tumor suppression protein to DNA response elements after genotoxic stress can be quantified by cell-based reporter gene assays as a DNA damage endpoint. Currently, bioassay evaluation of environmental samples requires further knowledge on p53 induction by chemical mixtures and on cytotoxicity interference with p53 induction analysis for proper interpretation of results. We investigated the effects of genotoxic pharmaceuticals (actinomycin D, cyclophosphamide) and nitroaromatic compounds (4-nitroquinoline 1-oxide, 3-nitrobenzanthrone) on p53 induction and cell viability using a reporter gene and a colorimetric assay, respectively...

Cyclophosphamide (CP) is one of the widely used anticancer agents; however, it has serious deleterious effects on normal host cells due to its nonspecific action. The essential trace element Selenium (Se) is suggested to have chemopreventive and chemotherapeutic efficacy and currently used in pharmaceutical formulations. Previous report had shown Nano-Se could protect CP-induced hepatotoxicity and genotoxicity in normal Swiss albino mice; however, its role in cancer management is still not clear. The aim of present study is to investigate the chemoprotective efficacy of Nano-Se against CP-induced toxicity as well as its chemoenhancing capability when used along with CP in Swiss albino mice against Ehrlich's ascites carcinoma (EAC) cells...

Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune syndrome that presents with personality changes, autonomic dysfunction, and neurologic deterioration. Most patients with this syndrome progress from psychosis to seizure to catatonia, often associated with abnormal movements, autonomic instability, and hypoventilation. First-line treatment constitutes resection of the associated neoplasm, corticosteroids, intravenous immunoglobulin, and plasma exchange. Second-line treatment includes rituximab and cyclophosphamide...
