In rats, learning and memory performance decline during normal aging, which makes this rodent species a suitable model to evaluate therapeutic strategies. In aging rats, insulin-like growth factor-I (IGF-I), is known to significantly improve spatial memory accuracy as compared to control counterparts. A constellation of gene expression changes underlie the hippocampal phenotype of aging but no studies on the effects of IGF-I on the hippocampal transcriptome of old rodents have been documented. Here, we assessed the effects of IGF-I gene therapy on spatial memory performance in old female rats and compared them with changes in the hippocampal transcriptome...

Botulinum neurotoxin A (BoNT/A) cleaves SNAP25 at the motor nerve terminals (MNT) and inhibits stimulus evoked acetylcholine release (SEAR). This causes skeletal muscle paralysis. However, younger neonatal mice (<P7; less than 7 days old) are resistant to the neuroparalytic effects of BoNT/A. That is, in vivo injection of BoNT/A at the innervations of Extensor digitorum longus (EDL) muscle in the hindlimbs inhibited the toe spread reflex within 24 hours following BoNT/A injection in adult mouse and in older (> P7) neonatal mice younger than 7 days-age remained unaffected by BoNT/A injection...

Endocrine disrupting flame retardant (FR) chemicals form a human health concern, that is investigated mostly from the perspective of adult- and early life exposure. No overview of studies on toddler exposure and health effects exist. However, toddlerhood is a critical developmental period and toddlers are at increased risk for exposure because of their age-specific behavior. This systematic review encompasses toddler FR exposure studies in three countries, associated health effects and potential environmental, demographic, or behavioral risk- or protective factors for toddler exposure...

BACKGROUND: Aggressive and disruptive behaviors often precede the onset of schizophrenia. In this register-based follow-up study with a case-control design, we wanted to investigate if serious delinquency was associated with future diagnoses of schizophrenia or schizoaffective disorder (here, broadly defined schizophrenia) among a nationwide consecutive sample of 15- to 19-year-old Finnish delinquents sent for a forensic psychiatric examination in 1989-2010. METHODS: The sample comprised 313 delinquents with no past or current psychotic disorder...

INTRODUCTION: The conservative surgery is more and more indicated for breast cancer. However, we still fear local recurrence which is mostly due to residual tumors?. Several techniques have been used to minimize theses residual tumors; one of them is the systematic circumferential tumor cavity shaving (SCTCS). METHODS: We sampled 75 female patients who had conservative surgery with positive shaved margins in the anatomopathology examination and to whom a complementary treatment with mastectomy have been decided...

Mitochondria form dynamic networks which adapt to the environmental requirements of the cell. We investigated the aging process of these networks in human skin cells in vivo by multiphoton microscopy. A study on the age-dependency of the mitochondrial network in young and old volunteers revealed that keratinocytes in old skin establish a significantly more fragmented network with smaller and more compact mitochondrial clusters than keratinocytes in young skin. Furthermore, we investigated the mitochondrial network during differentiation processes of keratinocytes within the epidermis of volunteers...

There has recently been an increasing focus on the development of automatic processing of numerical magnitude. However, little effort has been made to explore automatic access to non-symbolic numerical magnitude in preschool children. In experiment 1, we used a non-symbolic physical size comparison task in 3- to 6-year-olds to examine developmental changes and the effect of ratio and counting principle knowledge. Results showed that the existence of automatic non-symbolic numerical processing began at age 3-4 years and size congruity effects tended to reduce with increasing age from 4 years old...

The emergence of first permanent molars (FPMs) and second permanent molars (SPMs) is an important developmental milestone influencing caries risk and the timing of sealant placement. Emergence times have been shown to vary by sex and race/ethnicity, while recent reports suggest a positive association with adiposity. Amid the changing demographics of the US population and the rising rates of pediatric overweight/obesity, we sought to examine the association of body mass index (BMI) with FPM/SPM emergence in a representative sample of US children and adolescents...

OBJECTIVE: The Danish hematuria guidelines were revised in January 2016. Before revision, it was recommended that asymptomatic microscopic hematuria in patients more than 40 years old should be routinely urologically investigated. In the revised guidelines, patients with asymptomatic microscopic hematuria are not recommended to be investigated, irrespective of age. The purpose of this study was to investigate whether asymptomatic microscopic hematuria was predictive of neoplasia of the urinary tract in a referred cohort of patients...

Fibrinogen (Fib) is a useful marker for predicting the severity of coronary artery disease (CAD) in adult population. However, whether Fib can be a predictor for the presence and severity of CAD in very young MI patients (≤35 years old) remains to be determined. A total of 418 males from 61,863 patients with MI who were under 35 years old were sequentially recruited in our study. The patients were divided into two main groups and three subgroups according to coronary angiograph and Gensini score (GS) system: no coronary artery stenosis (group A), the results of the coronary artery stenosis (group B); low GS, intermediate GS and high GS...
