History In November 2012, a previously healthy 31-year-old woman was admitted to our hospital with a 2-month history of right-sided numbness, diplopia, and intermittent nausea and dizziness. She did not have a history of fever, weight loss, headache, photophobia, seizure, or extremity weakness. Physical examination revealed left abduction limitation and right-sided hypoesthesia. Kernig and Brudzinski signs were absent, and pathergy test results were negative. Laboratory evaluation revealed normal complete and differential blood counts, normal serum chemistry, and normal immune function...

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)...

BACKGROUND: A high proportion of patients with relapsed classical Hodgkin's lymphoma achieve a response with the antibody-drug conjugate brentuximab vedotin, and the drug is well tolerated. We modified the escalated BEACOPP regimen (eBEACOPP; bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) and implemented brentuximab vedotin with the aim to reduce toxic effects while maintaining the protocol's efficacy. METHODS: We did an open-label, multicentre, randomised phase 2 study at 20 study sites in Germany...

Fullerenes with novel structures find numerous potential applications, particularly in the fields of biology and pharmaceutics. Among various fullerene derivatives, those exhibiting amphiphilic character and capable of self-assembly into vesicles are particularly interesting, being suitable for delayed drug release. Herein, we report the synthesis and self-assembly of biocompatible hollow nanovesicles with bilayer shells from amphiphilic functionalized fullerenes C60 R5 Cl (R=methyl ester of 4-aminobutyric/glutamic acid or phenylalanine)...

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...

Although numerous hypotheses have been proposed to prevent chemotherapy-induced alopecia (CIA), effective pharmaceuticals have yet to be developed. In our study, the back hairs of C57BL/6 mice were factitiously removed. These mice were then treated with cedrol or minoxidil daily. Mice with early-stage anagen VI hair follicles were treated with cyclophosphamide (CYP, 125mg/kg) to induce alopecia. The CYP-damaged hair follicles were observed and quantified by using a digital photomicrograph. The results demonstrated that the minoxidil-treated mice suffered from complete alopecia similar to the model 6days after CYP administration...

A model to predict the mass flows and concentrations of pharmaceuticals predominantly used in hospitals across a large number of sewage treatment plant (STP) effluents and river waters was developed at high spatial resolution. It comprised 427 geo-referenced hospitals and 742 STPs serving 98% of the general population in Switzerland. In the modeled base scenario, domestic, pharmaceutical use was geographically distributed according to the population size served by the respective STPs. Distinct hospital scenarios were set up to evaluate how the predicted results were modified when pharmaceutical use in hospitals was allocated differently; for example, in proportion to number of beds or number of treatments in hospitals...

Multiple endpoints can be used to evaluate chemotherapy-induced nausea and vomiting (CINV). These endpoints reflect the various combinations of vomiting, nausea and rescue antiemetic use in the acute (0-24 h), delayed (>24-120 h) and overall (0-120 h) periods after chemotherapy. As the choice of outcome measure could potentially change the interpretation of clinical trial results, we evaluated CINV rates using different endpoints on a single dataset from a prospective cohort. Data from 177 breast cancer patients receiving anthracycline and cyclophosphamide-based chemotherapy was used to calculate CINV control rates using the 15 most commonly reported CINV endpoints...

BACKGROUND: Combination of chemotherapy with a tyrosine-kinase inhibitor is effective in the treatment of Philadelphia chromosome-positive acute lymphoblastic leukaemia. Ponatinib is a more potent BCR-ABL1 inhibitor than all other tyrosine-kinase inhibitors and selectively suppresses the resistant T315I clones. We examined the activity and safety of combining chemotherapy with ponatinib for patients with Philadelphia chromosome-positive acute lymphoblastic leukaemia in this continuing phase 2 trial...

4-(4-Nitrobenzyl)pyridine (NBP) is a colorimetric indicator compound for many types of carcinogenic alkylating agents. Because of the similar reactivity of NBP and guanine in DNA, NBP serves as a DNA model. NBP assays are used in the toxicological screening of pharmaceutical compounds, detection of chemical warfare agents, environmental hygiene technology, preliminary toxicology tests, mutagenicity of medicinal compounds, and other chemical analyses. Nevertheless, the use of NBP as a DNA model suffers from the compound's low water solubility, its lack of reactive oxygen sites, and dissimilar steric encumbrance compared to DNA...
