Coexistence of resistance to thyroid hormone and ectopic thyroid: ten-year follow-up

SUMMARY Resistance to thyroid hormone (RTH) coexisting with ectopic thyroid is rare. Here we report a case of RTH with ectopic thyroid. A ten-year-old girl had been misdiagnosed as congenital hypothyroidism and treated with levothyroxine since she was born. Ten-year follow-up showed that the elevated thy...

Shortened telomere length in bipolar disorder: a comparison of the early and late stages of disease

Objective: Bipolar disorder (BD) has been associated with increased rates of age-related diseases, such as type II diabetes, metabolic syndrome, osteoporosis, and cardiovascular disorders. Several biological findings have been associated with age-related disorders, including increased oxidative stress, i...

Presencia de micronúcleos en células exfoliadas de la mucosa oral en personas expuestas a agentes genotóxicos

Con-ciencia (La Paz); 4 (2), 2016
Los micronúcleos son utilizados como biomarcadores para determinar daño en el ADN. Este daño es causado por agentes genotóxicos y puede ser el origen de mutaciones o cáncer. Con el propósito de determinar el riesgo genotóxico debido al trabajo y hábitos nocivos (tabaco y alcohol), se analizaron m...

Polimorfismo (+3954c>T) del gen IL-1B y su asociación con la resorción radicular apical externa post-tratamiento ortodóntico

El objetivo fue determinar la presencia del polimorfismo rs1143634 (+3954C>T) del gen Interleuquina 1 Beta (IL-1B) y su asociación con la resorción radicular apical externa (RRE) post-tratamiento ortodóntico. Se realizó un estudio piloto de individuos tratados con aparatología ortodontica, 13 (ca...

ABSTRACT This article presents a case of tick infestation of the lower eyelid by a previously unreported species. A 71-year-old male presented with a tick attached to the lower eyelid. The tick was identified morphologically, and then molecularly via polymerase chain reaction (PCR) and sequencing of its ...

Prevalence study of SNP c.421G>T in the ADAMTS2 gene responsible for dermatosparaxis in white dorper sheep in Brazil

Pesqui. vet. bras; 36 (2), 2016
Dermatosparaxis is an autosomal recessive disorder of connective tissue; the disorder is clinically characterized by skin fragility and hyperextensibility. Dermatosparaxis in White Dorper sheep is caused by a single nucleotide polymorphism (SNP) (c.421G>T) in the ADAM metalloproteinase with thrombospondi...
