π‐Expanded Nitrogen‐Cation (N+)‐Doped Polycyclic Aromatic Hydrocarbons: A Review of Intramolecular Cyclization Routes to Benzo[c]Quinolizinium, Triazinium, Pyridoquinazolinium, and Pyridoquinoxalinium Frameworks

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review surveys recent progress in the synthesis of extended aromatic quinolizinium derivatives via intramolecular SNAr and oxidative 6π‐electrocyclization. Conventional thermal approaches are discussed alongside emerging, sustainable activation methods such as electrosynthesis and photochemical processes.

Iodine Deficiency [PDF]

open access: yesEndocrine Reviews, 2009
Abstract Iodine deficiency has multiple adverse effects in humans, termed iodine deficiency disorders, due to inadequate thyroid hormone production. Globally, it is estimated that 2 billion individuals have an insufficient iodine intake, and South Asia and sub-Saharan Africa are particularly affected.

Iodine Deficiency

ODÜ Tıp Dergisi, 2023
Iodine deficiency is an important public health problem both in our country and around the world. Iodine deficiency and the health problems it causes, to the large-scale struggle involving health and aid organizations such as the World Health Organization, United Nations Children's Fund (UNICEF), to accept 21 October as the Global Day for the ...

Iodine-deficiency disorders

The Lancet, 2008
2 billion individuals worldwide have insufficient iodine intake, with those in south Asia and sub-Saharan Africa particularly affected. Iodine deficiency has many adverse effects on growth and development. These effects are due to inadequate production of thyroid hormone and are termed iodine-deficiency disorders.

Iodine deficiency disorders

2011
Abstract Iodine (atomic weight 126.9 g/mol) is an essential component of the hormones produced by the thyroid gland. Thyroid hormones, and therefore iodine, are essential for mammalian life (1). The native iodine content of most foods and beverages is low, and the most commonly consumed foods provide 3–80 μg/serving (1).

Iodine deficiency in Turkey

European Journal of Pediatrics, 1999
Turkey is an iodine deficiency area. The overall goitre prevalence is thought to be 30%, and most epidemiological studies give figures compatible with mild to moderate iodine deficiency. However, it is suspected that there are regions where iodine deficiency might be more severe than previously known.

Epidemiology of iodine deficiency

Trends in Endocrinology & Metabolism, 1992
Iodine deficiency (ID) causes goiter, cretinism, neonatal hypothyroidism, irreversible mental retardation, and child and infant death. Over one billion people are at risk, most of them in developing countries. While ID is the primordial factor in these conditions, other environmental and host factors significantly modify the magnitude and clinical ...
