The clinical manifestations of cow's milk protein allergy (CMPA) in neonates are non-specific and involve multiple organ systems. CMPA may also adversely affect physical growth and central nervous system development in neonates, lead to functional disorders, and increase anxiety and stress among family members. Due to the lack of specific clinical manifestations and diagnostic methods, the diagnosis and management of CMPA in neonates continue to pose significant clinical challenges.

Comparative studies of seafood and reptile α- and β-parvalbumins.

Protein Sci

December 2024

Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, Michigan, USA.

Small calcium-binding proteins such as parvalbumins (PVs) are major seafood and fish allergens. However, the impact of structural changes on their capacity to bind IgE has not been studied in detail. Therefore, fish and reptilian PVs, as well as human α-PV, were selected for biochemical, structural, and IgE binding studies.

Article Synopsis
  • Early life stress, like maternal separation in rats, impacts gut-brain communication and the microbiota, affecting later risk for stress-induced disorders differently in males and females.
  • The research involved analyzing fecal samples and assessing changes in pain sensitivity and behavior in adulthood, revealing four distinct clusters: resilient, pain, immobile, and comorbid, each with unique gut microbiota profiles.
  • This study highlights how early gut microbiota changes can define adult behavioral responses, marking a step forward in understanding the relationship between gut health and stress resilience or susceptibility.

Article Synopsis
  • The study aimed to investigate whether maternal egg consumption during lactation can help prevent egg allergies in infants by promoting immune tolerance.
  • Researchers collected data from mothers on their egg intake, breastfeeding practices, and infants' health, particularly looking at instances of eczema and allergies at 6 and 12 months.
  • Results showed that maternal egg consumption did not significantly affect allergy development, but infants with eczema at 6 months had a higher risk of developing egg allergies by 12 months, highlighting the need to reduce skin exposure to allergens.

Background: Ticks are significant vectors of pathogens, including viruses, bacteria, and protozoa. With approximately 900 tick species worldwide, many are expanding their geographical range due to changing socioeconomic and climate factors. The Danube Delta, one of Europe's largest wetlands, is an ecosystem that, despite its ecological importance, remains understudied concerning the risk of introducing new tick-borne viruses.

Irritable bowel syndrome (IBS) is a common intestinal disease characterized by abdominal pain, abdominal distension and irregular defecation frequency, and it has had a high incidence and low cure rate in recent years. Visceral hypersensitivity (VH) is one of the main physiological indicators of IBS, and TRPV1 and TRPM8 (transient receptor potential vanilloid 1 and melastatin 8) play crucial roles in VH and are widely distributed in the intestine, significantly impacting abdominal pain in IBS patients. Under the guidance of PRISMA, four databases were systematically searched at the outset, including PubMed, Web of Science, Embase, and Cochrane Library.

Oridonin Suppresses Mast Cell Degranulation and Alleviates Ovalbumin-Induced Allergic Rhinitis.

Biol Pharm Bull

November 2024

Laboratory of Bioresponse Regulation, Graduate School of Pharmaceutical Sciences, Osaka University.

Incidence of type I allergies, such as hay fever, is continuously increasing in developed countries, including Japan. Type I allergies are triggered by chemical mediators, such as histamine, which are released via immunoglobulin E (IgE)-mediated mast cell degranulation. Therefore, medications inhibiting the synthesis, release, and receptor binding of these mediators are commonly used to manage type I allergy symptoms.

IgE antibodies raised against innocuous environmental antigens cause allergic diseases like allergic rhinitis, food allergy, and allergic asthma. While some allergies are often outgrown, others (peanut, shellfish, tree nut) are lifelong in the majority of individuals. Lifelong allergies are the result of persistent production of allergen-specific IgE.

The application of the amidohydrolase enzyme, L-asparaginase (ASNase), as a biocatalyst in the food and pharmaceutical industries has garnered significant interest. However, challenges such as hypersensitivity reactions, limited stability, and reusability under various operational conditions have hindered its cost-effective utilization. This paper introduces a novel nano-support for ASNase immobilization, namely the nanocomposite of iron oxide magnetic nanoparticles and amino acid-decorated graphene oxide (GO-Asp-FeO).

Background: The increase in allergic diseases in children has coincided with the westernization of lifestyles. Although clustering of modifiable lifestyles has been frequently reported in children, there is limited research on how lifestyle factors collectively contribute to allergic conditions. Our aim was to identify lifestyle clusters among Finnish school-aged children and explore their associations with the prevalence of allergic disease symptoms and sensitization.
