Two non-specific indicators of stress: Enamel hypoplasia and Harris lines
Harris lines (HL) and enamel hypoplasia (EH) are two non-specific indicators of stress, commonly used in the reconstruction of the health status in past and present populations. The aim of this study was to determine if there is a correlation between these two markers. To achieve this aim, a sample …

Cell-specific roles for CASK in the pathology of Optic Nerve Hypoplasia
Optic Nerve Hypoplasia (ONH) is the leading cause of childhood blindness in developed nations and its prevalence has been rising. Yet, we know little about the genetic, molecular, or cellular mechanisms underlying ONH. A previous study described ONH in a cohort of patients with mutations in CASK, …

Changes in Suid and Caprine Husbandry Practices Throughout Dynastic Egypt Using Linear Enamel Hypoplasia (LEH)
Linear enamel hypoplasia (LEH) is the most commonly identified form of enamel defect in teeth. Defined as a deficiency in enamel thickness encountered during dental development, LEH can occur as horizontal lines or depressions of irregular enamel, or clusters of pitting on the enamel surface. These …

Enamel hypoplasia in modern and archaeological caprine populations: The development and application of a new methodological approach
… domestic animals has demonstrated that enamel hypoplasia is a potentially valuable tool for investigating a range of archaeological topics including domestication and animal management strategies. However, research into archaeological domestic populations has been hindered by the difficulty of …

Putting teeth into the developmental origins hypothesis: A longitudinal study of early childhood malnutrition, enamel hypoplasia and adolescent health in Amazonian Bolivia
… early childhood exposures and dental enamel hypoplasia (EH) and to evaluate EH as a predictor of adolescent anthropometrics and biomarkers. We conducted analyses using data from 349 Tsimane’ adolescents in Amazonian Bolivia, collected between 2002-2010 and in 2015. In 2015, we examined EH in …

The identification and measurement of autistic features in children with optic nerve hypoplasia, "isolated" hypopituitarism and varying combinations of septo-optic Dysplasia
… with Septo Optic Dysplasia and Optic Nerve Hypoplasia demonstrate autistic phenomenology (Parr et al., 2008; Ek et al., 2005; Pring & Ockelford 2005; Bahar et al., 2003). It was found in fifty-six children, aged between four to sixteen, with isolated Hypopituitarism, Septo Optic Dysplasia …

Pathophysiology of Small Testes in Beef Bulls: Histopathological Features of Testes and Epididymides, Seminal Characteristics, and Endocrine Profiles (Testicular Hypoplasia, Degeneration, Breeding Soundness, Scrotal Circumference)
Seventeen beef bulls (2 to 3 1/2 years of age) with a scrotal circumference (SC) ranging from 27 to 40.5 cm were used to study the pathophysiology of small testes. All four bulls having a SC of 30 cm) and azoospermic or oligospermic (and having a SC < 30 cm) bulls. However, in the latter group, the …

Age-at-Formation and Duration of Linear Enamel Hypoplasia and Accentuated (Pathological) Striae in Ancient, Modern, and Forensic Populations as an Indicator of Differential Developmental Stress
… age-at-formation and duration of linear enamel hypoplasia (LEH) and accentuated striae (AS) in the mandibular canines of pre-Hispanic Maya individuals from Belize, migrants who died crossing the Texas-Mexico border, and modern American individuals from the Texas State Donated Skeletal Collection …

Mechanism of CASK-linked ophthalmological disorders
… and microcephaly with pontine and cerebellar hypoplasia (MICPCH, OMIM# 300749). CASK mutations are also frequently associated with optic nerve hypoplasia (ONH) which is the most common cause of childhood blindness in developed countries. Some patients with mutations in CASK have been also …

The Role of CASK in Central Nervous System Function and Disorder
… in microcephaly with pontine and cerebellar hypoplasia (PCH) and also optic nerve hypoplasia (ONH) in heterozygous mutations. Herein, I used various molecular and genetic strategies to uncover the role of the CASK protein in brain function and pathogenesis of cerebellar hypoplasia associated …

Dental defects and rubella embryopathy: a clinical study of fifty children
… rubella children studied, 90 per cent had enamel hypoplasia, 78 per cent had tapered teeth, and 18 per cent had notched anterior teeth. Among the normal children studied, 26 per cent had enamel hypoplasia, 18 per cent had tapered teeth, and none had notched teeth. No other dentofacial …

Pastoralism, Agriculture, and Stress: A Comparative Analysis of Two 19th Century Qing Dynasty Populations
… cribra orbitalia, and linear enamel hypoplasia were assessed macroscopically. Results show that in all pathological conditions except cribra orbitalia, stress indicators were significantly more frequent in the agriculturalist Karluk sample than in the pastoralist Urga sample; cribra …

Dental pathology, wear and developmental defects in South African hominins
… recorded include antemortem chipping, enamel hypoplasia, caries, occlusal wear, tertiary dentine, abscesses, and periodontal disease. Clear differences in frequencies were found in the different South African hominin species. Homo naledi displays high rates of chipping, especially small …
