BACKGROUND: A modest proportion of patients with early stage hormone receptor-positive (HR+), HER2-negative (HER2-) breast cancer benefit from adjuvant chemotherapy. Traditionally, treatment recommendations are based on clinical/pathologic criteria that are not predictive of chemotherapy benefit. Multigene assays provide prognostic and predictive information that can help to make more informed treatment decisions. The MAGIC survey evaluated international differences in treatment recommendations, how traditional parameters are used for making treatment choices, and for which patients treating physicians feel most uncertain about their decisions...

Inhibition of protein degradation is one of strategies for suppression of uncontrolled proliferation of cancer cells. Proteolytic degradation in cells is mainly ensured by proteasome and its inhibition by bortezomib showed benefit in clinical use for the treatment of multiple myeloma. We report here the library of antiproteasomal O-benzyl salicylamides built from leucine and phenylalanine. Prepared compounds displayed antiproliferative activity on K562, CEM and U266 cancer cell lines, ranging from high micromolar to submicromolar GI50 values...

Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the US Environmental Protection Agency (EPA), not including ozone and particulate matter. However, surface observations of HCHO are sparse and the EPA monitoring network could be prone to positive interferences. Here we use 2005-2016 summertime HCHO column data from the OMI satellite instrument, validated with high-quality aircraft data and oversampled on a 5 × 5 km(2) grid, to map surface air HCHO concentrations across the contiguous US...

BACKGROUND: Aspiration can occur in patients of any age group, but it can be prevented. The primary population at risk is made up of survivors of cancer because of their increased risk of mucositis, mucosal atrophy, and dysphagia associated with chemotherapy, radiotherapy, and the disease process itself. The rate of incidence of aspiration cannot be quantified, because minor cases of aspiration often go unreported. Sequelae ensuing from aspirations can include pneumonia, end-stage kidney disease, dialysis, and death...

Mangosteen (Garcinia mangostana L.) is one of the most popular tropical fruits (called the "Queen of Fruits"), and is a rich source of oxygenated and prenylated xanthone derivatives. In the present work, phytochemical investigation has resulted in one new prenylated xanthone and 13 known xanthones isolated from the pericarp of G. mangostana. Their structures were established by spectroscopic data analysis, including X-ray diffraction. The new one was further tested for cytotoxic activity against seven cancer cell lines (CNE-1, CNE-2, A549, H490, PC-3, SGC-7901, U87), displaying the half maximal inhibitory concentration (IC₅0) values 3...

Lead (Pb) contamination of foods and especially of frequently consumed vegetables is a growing public health concern worldwide. Although levels of exposure in developed countries have declined over the past decades, the same cannot be said of developing countries. Health risk assessment has increasingly been employed to determine the potential hazard of heavy metal exposure to humans. In this study vegetable samples (tomatoes, red pepper, brown beans, lettuce, cabbage, Irish potatoes, onions, green beans and carrot), soil samples, irrigation water and sediment samples were collected from the Dilimi River, Bukuru and Barkin Ladi communities in north central Nigeria and analyzed for Pb content using atomic absorption spectroscopy...

Background: HIV-induced immunodeficiency has been implicated as a key factor for risk of cancer. Neoplasia is considered to result from accumulation of damage to the genome. Polymorphisms in repair genes, such as the XRCC1 and WRN, have been associated with susceptibility to development of cancer in patients with HIV/AIDS. The aim of this study was to analyze the frequency of polymorphisms in XRCC1 (Arg399Gln) and WRN (Cys1367Arg) in patients with HIV/AIDS with or without cancer. Materials and Methods: Genotyping for analysis of polymorphisms was carried out by PCR (Polymerase Chain Reaction) and RFLP (Restriction Fragment Length Polymorphism)...

Stine F Pedersen, Ivana Novak, Frauke Alves, Albrecht Schwab, Luis A Pardo
We present here the hypothesis that the unique microenvironmental pH landscape of acid-base transporting epithelia is an important factor in development of epithelial cancers, by rendering the epithelial and stromal cells pre-adapted to the heterogeneous extracellular pH (pHe ) in the tumor microenvironment. Cells residing in organs with net acid-base transporting epithelia such as the pancreatic ductal and gastric epithelia are exposed to very different, temporally highly variable pHe values apically and basolaterally...
