Integrated Transcriptomic and Metabolomic Analyses of Cold-Tolerant and Cold-Sensitive Pepper Species Reveal Key Genes and Essential Metabolic Pathways Involved in Response to Cold Stress.

Int J Mol Sci 2022 Jun 15;23(12). Epub 2022 Jun 15.

Key Laboratory for Quality Regulation of Tropical Horticultural Crops of Hainan Province, College of Horticulture, Hainan University, Haikou 570228, China.

Cold stress, triggered by particularly low temperatures, is one of the most severe forms of abiotic stress in pepper plants and a major constraint to the global pepper industry, threatening crop production and food security. To acclimatize to extreme conditions, the plant undergoes numerous modifications, including genetic and metabolic modulations. A thorough study of both the genetic and metabolic alterations of plants in response to cold stress is vital to understanding and developing the cold stress resistance mechanism. Read More

Follow-Up of a Rare Case of Eosinophilic Gastroenteritis Associated with Persistent Blood Eosinophilia and Multiple Food Allergies.

Diagnostics (Basel) 2022 Jun 2;12(6). Epub 2022 Jun 2.

Clinical Department 5, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania.

Eosinophilic gastroenteritis (EGE) is a subgroup of the eosinophilic gastro-intestinal disorders (EGIDs), characterized by eosinophilic infiltration and chronic inflammation of the gastrointestinal tract. These are rare diseases with still incompletely elucidated causes and mechanisms, with frequently delayed diagnosis and variable outcome. Despite increased interest in eosinophilic diseases in recent years, fewer data have been published on EGE and no standardized diagnostic and therapeutic approach exists. Read More

Dyspepsia is a disorder characterized by dyspeptic symptoms which are located in the epigastrium and related to digestion of food in the initial part of the digestive system. In functional dyspepsia, unlike organic dyspepsia, there is no underlying organic disease that would cause dyspeptic symptoms. Immune and mucosal function changes, gastric dysmotility, different composition of the gastrointestinal microbiota, and altered central nervous system processing are considered responsible for the onset of the disorder.

Toulouse Biotechnology Institute (TBI), Université de Toulouse, CNRS, INRAE, INSA, Toulouse, France.

Gut disorders associated to irritable bowel syndrome (IBS) are combined with anxiety and depression. Evidence suggests that microbially produced neuroactive molecules, like γ-aminobutyric acid (GABA), can modulate the gut-brain axis. Two natural strains of and one mutant were characterized for their GABA production and tested in rat by oral gavage for their antinociceptive properties. Read More

Climate change and allergic diseases in children and adolescents.

Allergol Immunopathol (Madr) 2022 28;50(S Pt 1):7-16. Epub 2022 Apr 28.

Division of Allergy, Clinical Immunology and Rheumatology, Department of Pediatrics, Escola Paulista de Medicina, Federal University of São Paulo, São Paulo, Brazil;

Introduction: The Anthropocene is used to describe the most recent period where major disruptions in Earth's system processes have resulted from humanity's increasing ecological footprint. Climate change affects the social and environmental determinants of good health, such as clean air, stable ecosystems, safe drinking water, and sufficient and safe food, and they seem to be closely related to air pollution.

Objectives: This article aims to review the evidence of how extreme weather events and indoor and outdoor pollution are associated with insufficient lung growth in early life, changes in lung function, and the increase in respiratory infections, favoring the development of allergic respiratory diseases.

The Microbiome as a Gateway to Prevention of Allergic Disease Development.

J Allergy Clin Immunol Pract 2022 Jun 16. Epub 2022 Jun 16.

Department of Health Security, Finnish Institute for Health and Welfare, Kuopio, Finland; Institute of Public Health and Clinical Nutrition, University of Eastern Finland, Kuopio, Finland.

Allergic diseases exclusively affect tissues that face environmental challenges and harbor endogenous bacterial microbiota. The microbes inhabiting the affected tissues may not be mere bystanders in this process but actively affect the risk of allergic sensitization, disease development and exacerbation or abatement of symptoms. Experimental evidence provides several plausible means by which the human microbiota could influence the development of allergic diseases including, but not limited to, effects on antigen presentation and induction of tolerance and allergen permeation by endorsing or disrupting epithelial barrier integrity.

Filaggrin loss-of-function mutations are associated with persistence of egg and milk allergy.

J Allergy Clin Immunol 2022 Jun 14. Epub 2022 Jun 14.

Max-Delbrück-Center for Molecular Medicine (MDC), Berlin, Germany; Clinic for Pediatric Allergy, Experimental and Clinical Research Center, Charité-Universitätsmedizin Berlin, Berlin, Germany.

Background: A genetic defect in the epidermal barrier protein filaggrin plays a major role in the etiology of eczema and associated allergic airways diseases. However, it is still controversial to what extend loss-of-function (LOF) mutations in the filaggrin gene (FLG) contribute to the development and persistence of food allergies.

Objective: We tested association of FLG LOF mutations with allergic reactions to diverse foods and investigated their potential effect on the persistence of early food allergies. Read More

PrEggNut Study: protocol for a randomised controlled trial investigating the effect of a maternal diet rich in eggs and peanuts from <23 weeks' gestation during pregnancy to 4 months' lactation on infant IgE-mediated egg and peanut allergy outcomes.

BMJ Open 2022 Jun 13;12(6):e056925. Epub 2022 Jun 13.

SAHMRI Women and Kids, South Australian Health and Medical Research Institute, Adelaide, South Australia, Australia.

Introduction: Clinical studies supported by immunological data indicate early life intervention strategies to be promising in reducing the growing global burden of food allergies. The events that predispose to food allergy, including the induction of allergen-specific immune responses, appear to be initiated early in development. Early exposure to food allergens in utero and via breast milk is likely to be important in initiating oral tolerance. Read More

Patient selection for milk and egg ladders using a food ladder safety checklist.

Allergy Asthma Clin Immunol 2022 Jun 12;18(1):51. Epub 2022 Jun 12.

Division of Allergy and Immunology, Department of Pediatrics, University of British Columbia, Vancouver, BC, Canada.

A food ladder is a form of home-based dietary advancement therapy that gradually increases exposure to an allergenic food through the gradual introduction of egg or milk containing food with increasing quantity and allergenicity from extensively heated forms, such as baked goods, to less processed products. While widely considered safe, the food ladder is not risk-free and most of the egg and milk ladder studies only included preschoolers with mild egg and milk allergies, and with no or well-controlled asthma. We propose a Food Ladder Safety Checklist to assist with patient selection using "4 A's" based on available evidence for food ladders, including Age, active or poorly controlled Asthma, history of Anaphylaxis, and Adherence.

Electronic address:

Peanut allergy as one of the major causes of food-induced anaphylaxis is usually life-threatening for specific individuals. Nowadays, the effective remedy is avoidance of consuming allergen-containing food, urging monitoring the presence of peanut in foods. Herein, we proposed a closed-tube saltatory rolling circle amplification (SRCA) assay with hydroxynaphthol blue (HNB) for visual on-site detection of peanut allergen, displaying highly specificity for Ara h 1-encoding gene.
