Ergot Alkaloids Mycotoxins in Cereals and Cereal-Derived Food Products: Characteristics, Toxicity, Prevalence, and Control Strategies
agronomy Review Ergot Alkaloids Mycotoxins in Cereals and Cereal-Derived Food Products: Characteristics, Toxicity, Prevalence, and Control Strategies Sofia Agriopoulou Department of Food Science and Technology, University of the Peloponnese, Antikalamos, 24100 Kalamata, Greece; [email protected]; Tel.: +30-27210-45271 Abstract: Ergot alkaloids (EAs) are a group of mycotoxins that are mainly produced from the plant pathogen Claviceps. Claviceps purpurea is one of the most important species, being a major producer of EAs that infect more than 400 species of monocotyledonous plants. Rye, barley, wheat, millet, oats, and triticale are the main crops affected by EAs, with rye having the highest rates of fungal infection. The 12 major EAs are ergometrine (Em), ergotamine (Et), ergocristine (Ecr), ergokryptine (Ekr), ergosine (Es), and ergocornine (Eco) and their epimers ergotaminine (Etn), egometrinine (Emn), egocristinine (Ecrn), ergokryptinine (Ekrn), ergocroninine (Econ), and ergosinine (Esn). Given that many food products are based on cereals (such as bread, pasta, cookies, baby food, and confectionery), the surveillance of these toxic substances is imperative. Although acute mycotoxicosis by EAs is rare, EAs remain a source of concern for human and animal health as food contamination by EAs has recently increased. Environmental conditions, such as low temperatures and humid weather before and during flowering, influence contamination agricultural products by EAs, contributing to the Citation: Agriopoulou, S. Ergot Alkaloids Mycotoxins in Cereals and appearance of outbreak after the consumption of contaminated products. The present work aims to Cereal-Derived Food Products: present the recent advances in the occurrence of EAs in some food products with emphasis mainly Characteristics, Toxicity, Prevalence, on grains and grain-based products, as well as their toxicity and control strategies. -

Symptoms are caused by an enterotoxin, for which 6% of type A strains carry the structural gene. This enterotoxin is released when ingested cells sporulate in the small intestine. Research on C. perfringens has been limited to a couple of strains that sporulate well in Duncan and Strong (DS) medium. These abundantly sporulating strains in vitro are not necessarily a representation of the most dangerous strains in vivo. Therefore, sporulation was optimized for C. perfringens strains in general. None of the tested media and methods performed well for all strains, but Peptone-Bile- Theophylline medium (with and without starch) yielded highest spore numbers. -
Advances in Anticancer Antibody-Drug Conjugates and Immunotoxins

These bio- pharmaceuticals have potential in this field, as they can selectively direct highly potent cytotoxic agents to cancer cells that present tumor-associated surface markers, thereby minimizing systemic toxicity. The activity of some conjugates is of particular interest receiving increasing attention, thanks to very promising clinical trial results in hematologic cancers. Over twenty antibody-drug conjugates and eight immunotoxins in clinical trials as well as some recently approved drugs, support the maturity of this approach. This review focuses on recent advances in the development of these two classes of biopharmaceuticals: conventional toxins and anticancer drugs, together with their mechanisms of action. The processes of conjugation and purification, as reported in the literature and in several patents, are discussed and the most relevant results in clinical trials are listed. Innovative technologies and preliminary results on novel drugs and toxins, as reported in the literature and in recently-published patents (up to February 2013) are lastly examined.

AMATOXIN MUSHROOM POISONING in NORTH AMERICA 2015-2016 by Michael W
VOLUME 57: 4 JULY-AUGUST 2017 www.namyco.org AMATOXIN MUSHROOM POISONING IN NORTH AMERICA 2015-2016 By Michael W. Beug: Chair, NAMA Toxicology Committee Assessing the degree of amatoxin mushroom poisoning in North America is very challenging. Understanding the potential for various treatment practices is even more daunting. Although I have been studying mushroom poisoning for 45 years now, my own views on potential best treatment practices are still evolving. While my training in enzyme kinetics helps me understand the literature about amatoxin poisoning treatments, my lack of medical training limits me. Fortunately, critical comments from six different medical doctors have been incorporated in this article. All six, each concerned about different aspects in early drafts, returned me to the peer reviewed scientific literature for additional reading. There remains no known specific antidote for amatoxin poisoning. There have not been any gold standard double-blind placebo controlled studies. There never can be. When dealing with a potentially deadly poisoning (where in many non-western countries the amatoxin fatality rate exceeds 50%) treating of half of all poisoning patients with a placebo would be unethical. Using amatoxins on large animals to test new treatments (theoretically a great alternative) has ethical constraints on the experimental design that would most likely obscure the answers researchers sought. We must thus make our best judgement based on analysis of past cases. Although that number is now large enough that we can make some good assumptions, differences of interpretation will continue. Nonetheless, we may be on the cusp of reaching some agreement. Towards that end, I have contacted several Poison Centers and NAMA will be working with the Centers for Disease Control (CDC). -

Changing Pattern of Epidemic Dropsy in North India
Epidemic Dropsy in North India N. Sharma et al. ORIGINAL ARTICLE Changing Pattern of Epidemic Dropsy in North India NAVNEET SHARMA1,*, NAINA MOHAN 2, ASHISH BHALLA1, AMAN SHARMA1, SURJIT SINGH 1 1 The Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, Chandigarh, India 2 King's College London, Strand, London, United Kingdom Abstract Background: Epidemic dropsy occurs due to ingestion of mustard oil contaminated with oil from Argemone mexicana, leading to edema and tenderness of the abdomen, upper and lower limbs. In this study, clinical profiles of patients presented with epidemic dropsy in north India are described. Methods: This was a prospective study of patients presented with epidemic dropsy to the emergency department of Nehru Hospital, during the period from March 2004 to December 2011. Inclusion criteria were patients presenting with tender bilateral pitting leg edema and dermal telangiectasia. Clinical and laboratory data of patients were entered into case record forms at the time of presentation until discharge from the hospital. Results: Leg edema was the principal symptom in our series, and was in concurrence with current literature. Erythema has only been reported in 35-82% of published series, though it was present in all of our patients. Similarly, features such as diarrhea, hepatomegaly and anemia were more frequent in our cases compared to the literature. Furthermore, pancytopenia which was documented on peripheral blood counts in 54% of our cases has never been reported before. Conclusion: Epidemic dropsy should be considered in patients presenting with progressive erythema, edema, and tenderness of the limbs who had a history of consumption of mustard oil and confirmation of Argemone oil contamination according to laboratory tests. -

Less well publicized are the cases of psychoses associated with convulsive ergotism. Lysergic acid amide a powerful hallucinogen having one.-tenth the hallucinogenic activity of LSD-25 is produced by natural sources. This article attempts to show that convulsive ergot psychoses are mixed psychoses caused by lysergic acid amide or similar hallucinogens combined with nervous system -
