Abstract
INTRODUCTION Methadone and buprenorphine are effective and safe treatments for opioid use disorder (OUD) and also reduce overdose and all-cause mortality. Identifying and reaching providers of medication for opioid use disorder (MOUD) has proven difficult for prospective patients and researchers. OBJECTIVES To assess the accuracy of government-maintained lists of Arizona (AZ) providers prescribing MOUD, and the extent to which these providers are accessible for treatment. METHODS A two-phase study used a listing of 2376 AZ MOUD providers obtained from the U.S. Drug Enforcement Administration and the Substance Abuse and Mental Health Services Administration. Phase 1 assessed the accuracy of the listing using internet confirmatory research from May-October 2022. Phase 2 used the resulting list of 838 providers to assess provider availability, type of MOUD treatment provided, and accepted payment through secret shopper calls between November 16 and 30, 2022. RESULTS Just over half (52.2 %, n = 1240) of providers were removed from the original listing during Phase 1. One quarter (25.9 %) were no longer in practice. Among the 833 eligible for the secret shopper Phase 2 study, 36.6 % (n = 307) were reached and identified as providing MOUD. A vast majority (88.1 %) of MOUD providers indicating treatment type were accepting new patients, however methadone was identified far more frequently than was likely permitted or provided for OUD. Providers were 5.5 times more likely to accept new patients if they accepted cash payment for services, and 4.9 times more likely if they accepted Medicaid. Rural areas remained underserved. CONCLUSIONS The active population of MOUD providers is far smaller than surmised. DEA and SAMHSA provider listings are not sufficiently accurate for survey research sampling. Other means of representative sampling will need to be devised, and trusted lists of providers for prospective patients should be promoted, publicly available, and regularly maintained for accuracy. Providers that offer treatment should assure that public-facing staff have basic information about the practice, the treatment offered, and conditions for taking new patients. Concerted efforts must assure rural access at the most local levels to reduce patient travel burden.

Abstract
Mycotoxins are toxic secondary metabolites produced by fungi. These compounds have different structures and target different organs, acting at different steps of biological processes inside the cell. Around 32 mycotoxins have been identified in fungal Penicillium spp. isolated from food and feed. Some of these species are important pathogens which contaminate food, such as maize, cereals, soybeans, sorghum, peanuts, among others. These microorganisms can be present in different steps of the food production process, such as plant growth, harvest, drying, elaboration, transport, and packaging. Although some Penicillium spp. are pathogens, some of them are used in elaboration of processed foods, such as cheese and sausages. This review summarises the Penicillium spp. mycotoxin toxicity, focusing mainly on the subgenus Penicillium, frequently found in food and feed. Toxicity is reviewed both in animal models and cultured cells. Finally, some aspects of their regulations are discussed.

Abstract
Furoxan derivatives with in vitro cytotoxic activity were investigated as antitumoral agents in vivo. The compounds were tested in murine models of both CCRFS-180 II sarcoma and mammary adenocarcinoma. Two of the furoxan derivatives considered here, 3-formyl-4-phenyl-1,2,5-oxadiazole N2-oxide and 3-carbonitrile-4-phenyl-1,2,5-oxadiazole N2-oxide, present in vivo antitumoral activity. They were able to produce more than 90% of tumoral necrosis under the experimental protocol of administration and posology employed. NO-releasing capacity of furoxans may explain the anti-neoplastic activity of these compounds.
