Summary
Tree nut allergies, affecting almonds to walnuts, are lifelong and can cause severe reactions. Diagnosis is challenging, often requiring advanced molecular techniques for accurate identification.
Area of Science:
- Botany and Immunology
- Focuses on the botanical definition of nuts and the immunological responses to tree nut allergens.
Background:
- Tree nut allergy encompasses a range of nuts including almonds, walnuts, and cashews.
- Unlike many childhood allergies, tree nut allergies typically persist throughout life.
- These allergies are a significant cause of fatal allergic reactions in all age groups.
Purpose of the Study:
- To define tree nuts botanically.
- To outline the scope of tree nut allergies.
- To discuss the persistent nature and severity of tree nut allergies.
Main Methods:
- Botanical classification of nuts.
- Epidemiological analysis of tree nut allergy prevalence.
- Review of diagnostic challenges and molecular techniques.
Main Results:
- Tree nuts are botanically defined as single-seeded fruits with a hard pericarp.
- Allergies to tree nuts are common, persistent, and geographically variable.
- Prevalence differs, with hazelnuts common in Northern Europe and walnuts in the USA.
Conclusions:
- Tree nut allergies are a serious, lifelong health concern.
- Accurate diagnosis is complex and necessitates advanced molecular diagnostic tools.
- Understanding epidemiological variations is crucial for public health strategies.

1.1K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

01:30Hypersensitivities
1.5K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:202° Amines to N-Nitrosamines: Reaction with NaNO2
4.7K
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

3.6K
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
