Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Except in the family Salamandridae, the head, body, and tail have a number of vertical depressions in the surface which run from the mid-dorsal region to the ventral area and are known as costal grooves. Their function seems to be to help keep the skin moist by channeling water over the surface of the body. [13] Sirens have an eel-like appearance.
However, the interaction between iron and vitamin C can generate free radicals, particularly in cases of iron overload. In iron deficiency, vitamin C aids absorption. Aspirin use in the elderly, often for cardiovascular disease, is linked to lower serum ferritin levels. Iron deficiency can be managed through an iron-rich diet or supplementation.

Micronutrient deficiencies are considered a public health problem worldwide. For over 30 years it has been estimated that more than two billion people of all ages are affected by this burden, [1] while a recently published study based on individual-level biomarker data estimated that there are 372 million children aged 5 years and younger, and 1.2 billion non-pregnant women of reproductive age ...
Animal-source foods are a diverse group of foods that are rich in bioavailable nutrients including calcium, iron, zinc, vitamins B12, vitamin D, choline, DHA, and EPA. [11] Animal-source and plant-based foods have complimentary nutrient profiles and balanced diets containing both reduce the risk of nutritional deficiencies. [ 11 ]
Oxygenated and non-oxygenated blood are mixed together in the venous system, which causes the partial pressure of oxygen within cardiac blood to typically be low. [ 15 ] Plethodontids can tolerate hypoxia for prolonged periods by reducing their metabolic rate instead of by relying on anaerobic cutaneous respiration, as initially theorized.
