Objective: Rice, one of the first solid foods introduced to infants, is 10 times more absorbent of inorganic arsenic than any other grain. An evaluation has not been performed about practitioner knowledge of arsenic content in infant foods. The purpose of this survey was to determine pediatric practitioners' knowledge of current US Food and Drug Administration (FDA) recommendations to limit exposure to arsenic-containing foods in infants.
Methods: This was a convenience sample of pediatric practitioners conducted as an online survey. The survey contained 19 questions related to knowledge of arsenic-containing foods, FDA recommendations, practitioner recommendations on feeding infants, and demographic information. Participants were recruited using organization list servs. Participants were reminded to complete the survey 2 months after the initial email. An infographic on arsenic was provided at the end of the survey.
Results: One hundred thirty-seven individuals completed the survey. The majority of respondents were physicians or pharmacists and have been in practice less than 6 years. Nine percent of respondents (11/123) stated the FDA arsenic limit of 100 ppb. Sixteen percent (20/123) identified white rice as having a lower inorganic arsenic content than brown rice and 27% (36/132) identified that there is no difference in inorganic arsenic content between organic infant rice cereal and conventional infant rice cereal.
Conclusions: The vast majority of participants were not aware of the FDA's proposed limit on arsenic consumption or the concern of heavy metals in baby foods. More education is needed to increase knowledge regarding arsenic in baby foods.

Arsenic (As) occurs naturally in different forms and oxidation states. Amongst them, inorganic arsenic (iAs) is classified as both genotoxic and carcinogenic whilst other organic arsenic species are considered less toxic. As in rice is mainly present in the form of iAs which therefore poses a health risk to populations that consume rice as a staple food.

Breast cancer is the most common type of cancer in women worldwide. A common approach to cancer treatment in clinical practice is to use a combination of drugs to enhance the anticancer activity of drugs while reducing their side effects. In this regard, we evaluated the effectiveness of combined treatment with gemcitabine (GCB) and arsenic (ATO) and how they affect the cell death pathway in cancer cells.

Deep sea microbial communities play a significant role in global biogeochemical processes. However, the depth-wise metabolic potential of microbial communities in hydrothermally influenced Central Indian Ridge (CIR) and Southwest Indian Ridge (SWIR) remains elusive. In this study, a comprehensive functional microarray-based approach was used to understand factors influencing the metabolic potential of microbial communities and depth-driven differences in microbial functional gene composition in CIR and SWIR.

The retention and mobility of arsenic (As) in soil depend on various physical and chemical factors. The knowledge of the sorption-desorption chemistry of As in soil is necessary for predicting the fate and behavior of As in soil environments. Therefore, this study assessed different organic (sugarcane bagasse and vermicompost) and inorganic amendments (steel slag and fly ash) for their impact on sorption-desorption of As in texturally different contaminated soils (of sandy clay (SC) and sandy clay loam (SCL) texture) to understand the effect of amendments on As retention and mobility.
