There is a growing body of evidence supporting the synergistic roles of radiotherapy and immunotherapy in the treatment of malignancy. Published case studies of the abscopal effect have been reported with the use of ipilimumab and radiotherapy in metastatic melanoma, but evidence supporting the routine use of this combination of therapy is limited. We conducted a retrospective analysis to evaluate patients treated with ipilimumab for advanced melanoma at a single institution from May 2011 to June 2015. Patients were grouped into those who had received concurrent radiotherapy while on ipilimumab (Ipi-RT), and those who did not...

The environmental factors are expected to affect the ecotoxicity of heavy metals in the presence of engineered nanoparticles (NPs) in aquatic ecosystems. However, in sediment scenario, little is known regarding their impacts on the ecotoxicity of co-exposure of sediment-associated heavy metals and NPs. This study evaluated the impacts of different levels of organic matter (OM) (4.8-11.6%) and pH (6-9) on the ecotoxicological effects of co-exposure of sediment-associated titanium dioxide nanoparticles (TiO2-NPs) and cadmium (Cd) to a freshwater gastropod Bellamya aeruginosa...

OBJECTIVE: Uterine serous carcinoma(USC)is more aggressive compared to endometrioid adenocarcinoma, and often exhibits intraperitoneal spread, resulting in a poor prognosis. It is a rare subtype of uterine cancers, accounting for 5%of cases in Japan; therefore, optimal chemotherapy regimens for patients with advanced or recurrent disease have not been established. In the present study, we evaluated the safety and efficacy of carboplatin plus taxane chemotherapy for the treatment of patients withadvanced and recurrent USC...

Dried distillers grains with solubles (DDGS) have been used in production animal diets; however, overuse of DDGS can cause toxic concentrations of ruminal hydrogen sulfide gas (HS), resulting in polioencephalomalacia, a deleterious brain disease. Because HS gas requires an acidic rumen environment and diet can influence ruminal pH, it has been postulated that dietary manipulation could help mitigate HS production. The objective of this study was to assess the effect of dietary roughage and sulfur concentrations on HS production and rumen fermentation...

Acute lymphoblastic leukemia (ALL) accounts for 30% of all pediatric cancers. Currently available treatments exhibit toxicity and certain patients may develop resistance. Thus, less toxic and chemoresistance-reversal agents are required. In the present study, the potential effect of curcumin, a component of Curcuma longa, as a pharmacological co-adjuvant of several chemotherapeutic agents against ALL, including prednisone, 6-mercaptopurine, dexamethasone, cyclophosphamide, l-asparaginase, vincristine, daunorubicin, doxorubicin, methotrexate and cytarabine, was investigated in the REH ALL cell line cultures treated in combination with chemotherapeutic agents and curcumin...

We tested a series of sulfur-containing linear bisphosphonates against Toxoplasma gondii, the etiologic agent of toxoplasmosis. The most potent compound ( 22: , 1-[(n-decylsulfonyl)ethyl]-1,1-biphosphonic acid) is a sulfone-containing compound, which had an EC50 of 0.11 ± 0.02 μM against intracellular tachyzoites. The compound showed low toxicity when tested in tissue culture with a selectivity index of >2,000. 22: also showed high activity in vivo in a toxoplasmosis mouse model. The compound inhibited the Toxoplasma farnesyl diphosphate synthase (TgFPPS) but the concentration needed to inhibit 50% of the enzymatic activity (IC50) was higher than the concentration that inhibited 50% of growth...

The AXL receptor and its activating ligand, growth arrest-specific 6 (GAS6), are important drivers of metastasis and therapeutic resistance in human cancers. Given the critical roles that GAS6 and AXL play in refractory disease, this signaling axis represents an attractive target for therapeutic intervention. However, the strong picomolar binding affinity between GAS6 and AXL and the promiscuity of small molecule inhibitors represent important challenges faced by current anti-AXL therapeutics. Here, we have addressed these obstacles by engineering a second-generation, high-affinity AXL decoy receptor with an apparent affinity of 93 femtomolar to GAS6...

BACKGROUND & AIMS: Among the greatest hurdles to pancreatic cancer (PC) therapy is the limited tissue penetration of systemic chemotherapy due to tumor desmoplasia. The primary study aim was to determine the toxicity profile of EUS-guided fine-needle injection (EUS-FNI) with gemcitabine. Secondary endpoints included ability to disease downstage leading to a R0 resection, and overall survival at 6 months, 12 months, and 5 years after therapy. PATIENTS AND METHODS: In a prospective study from a tertiary referral center, gemcitabine (38mg/ml) EUS-FNI was performed in PC patients before conventional therapy...

Snakebite is a serious occupational hazard affecting mainly rural populations of tropical and subtropical developing countries. Lachesis muta (Bushmaster) bites are extremely serious but are rarely reported in the literature. Bushmaster envenomings are characterized by intense local pain, edema, neurotoxicity, hypotension, local hemorrhage, and dramatic systemic alterations. Antivenom treatment has regularly been used for more than a century; however, it fails to neutralize local tissue damage and hemorrhage, leading to morbidity or disabilities in victims...

BACKGROUND: α-Synuclein is a major component of pathologic inclusions that characterize Parkinson's disease. PRX002 is an antibody that targets α-synuclein, and its murine parent antibody 9E4 has been shown in preclinical studies to reduce α-synuclein pathology and to protect against cognitive and motor deteriorations and progressive neurodegeneration in human α-synuclein transgenic mice. METHODS: This first-in-human, randomized, double-blind, placebo-controlled, phase 1 study assessed the impact of PRX002 administered to 40 healthy participants in 5 ascending-dose cohorts (n = 8/cohort) in which participants were randomly assigned to receive a single intravenous infusion of study drug (0...

Mosquito-borne diseases are of major concern as they cause devastating health effects, morbidity, and mortality in the human population. Conventional pesticides have failed to curb the mosquito population due to the development of insensitivity in mosquitoes. Hence, higher dosages of pesticides along with their toxic solubilizers have been employed, which have led to raise in pesticide pollution load, environmental toxicity, and human health concerns. As a realisation for the requirement of alternative pesticides, the present study has involved in the formulation of a hydrodispersive nanometric colloidal form of deltamethrin (NDM), a type-II pyrethroid pesticide, from its hydroimmisicible parental form (PDM)...

BACKGROUND: Various polymorphisms have been detected in the UDP-glucuronosyltransferase 1A ( UGT1A ) gene, and UGT1A1 *28 and UGT1A1 *6 have important effects on the pharmacokinetics of irinotecan and the risk of severe toxicities during irinotecan therapy. This study was conducted to determine the maximum tolerated dose (MTD) of irinotecan chemotherapy according to the UGT1A1 genotype in previously treated lung cancer patients with the UGT1A1 *28 or UGT1A1 *6 polymorphism. METHODS: The eligibility criteria were as follows: lung cancer patients that had previously been treated with anticancer agents other than irinotecan, possessed the UGT1A1 *28 or UGT1A1 *6 polymorphism (group A included *28/*28, *6/*6, and *28/*6, and group B included *28 /- and *6 /-), were aged ≤75 years old, had a performance score of 0-1, and exhibited adequate bone marrow function...

Astrocytes, which have various important functions, have previously been associated with Parkinsons disease (PD), particularly in 1-methyl-4-phenylpyridinium (MPP+) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) models of PD. MPP+ is the toxic metabolite of MPTP and is generated by the enzymatic activity of monoamine oxidase B, which is predominantly located in astrocytes. MPP+ acts as a mitochondrial complex I inhibitor. Autophagy is an evolutionarily conserved self-digestion pathway in eukaryotic cells, which occurs in response to various types of stress, including starvation and oxidative stress...

Chemotherapy-containing regimens are effective for the treatment of advanced MALT lymphoma but due to the indolent course of this disease investigating the use of immunomodulatory, chemotherapy-free strategies appears reasonable. Based on the activity of lenalidomide (LEN) monotherapy for MALT lymphoma and promising results with LEN plus rituximab (R) in several B-cell malignancies, we have studied this combination for MALT lymphoma. In this multicenter phase II study (AGMT MALT-2), patients received R 375 mg/m2 d1 and LEN 20 mg d1-21 every four weeks...
