Children's episodic foresight, the ability to mentally project oneself into the future to pre-experience an event (e.g., Atance & O'Neill, 2005), begins to emerge early in the preschool years. Results from the Picture-book task (Atance & Meltzoff, 2005) have shown that children are generally capable of selecting an item needed in the future (from provided options), but young preschoolers have difficulty justifying their choice with future-oriented explanations. Because episodic foresight has typically been measured using forced-choice questions (such as the Picture-book task) less is known about children's more naturalistic and "open-ended" future thinking (i.e., more spontaneous forms of episodic foresight). Forty-eight 3-to 5-year-olds completed a new, open-ended version of the Picture-book task. Using a descriptive approach, we found that children were able to generate an appropriate item to bring with them to a future location, and that this ability improved with age. Temporal focus as well as internal (episodic) and external (semantic) details were explored in the context of children's explanations. Children's explanations were mostly present-oriented and included episodic and semantic details equally. Our findings extend our knowledge of children's episodic foresight by highlighting children's ability to solve future-oriented problems in an open-ended manner.This article describes a deep femoral arteriovenous fistula (AVF) diagnosed over a decade after a small caliber gunshot injury to the groin. The fistula persisted following 2 previous attempts at endovascular exclusion and was referred to our institution for further care. We describe the successful exclusion of the AVF via a combination of endovascular techniques. Postoperatively, obliteration was noted to be durable for 4 additional years of follow-up.Respiratory sinus arrhythmia (RSA) has been extensively investigated as a marker of adaptive emotional functioning in both children and adults, with studies linking RSA to temperamental dimensions such as positive affect and extraversion. However, few studies have examined the extent to which relations between RSA and temperament characteristics vary across ethnicity in childhood. We examined relations between respiratory sinus arrhythmia (RSA) and temperament dimensions (Activity Level, Task Orientation, and Affect-Extraversion) and the moderating role of ethnicity among preschoolers. Chinese- American (n = 28, Mage = 54.30 months) and European American (n = 32, Mage = 50.41 months) preschoolers were assessed for their temperament and RSA. Findings indicated higher levels of Affect-Extraversion among European American children. Ethnicity moderated the association between the baseline RSA and the Affect-Extraversion dimension of temperament, with a significant positive association found only for European American children. More research is needed to examine the effects of social-cultural experiences on the relation between children's affective regulation and autonomic functioning development.Chlorophyll (Chl) biosynthesis is one of the most important cellular processes essential for plant photosynthesis. Chl degradation pathway is also important catabolic process occurs during leaf senescence, fruit ripening and under biotic or abiotic stress conditions. Here we have systematically investigated the molecular evolution, gene structure, compositional analysis along with ENc plot, correspondence analysis and codon usage bias of the proteins and encoded genes involved in Chl metabolism from monocots and dicots. The gene and species specific phylogenetic trees using amino acid sequences showed clear clustering formation of the selected species based on monocots and dicots but not supported by 18S rRNA. Nucleotide composition of the encoding genes showed that average GC%, GC1%, GC2% and GC3% were higher in monocots. RSCU analysis depicts that genes from monocots for both pathways and genes for synthesis pathway from dicots only biased to G/C-ending synonymous codons but in degradation pathway most optimal codons (except UUG) in dicots biased to A/U-ending synonymous codons. We found strong evidence of episodic diversifying selection at several amino acid sites in all genes investigated. Conserved domain and gene structures were observed for the genes with varying lengths of introns and exons, involved in Chl metabolism along with some intronless genes within synthesis pathway. ENc and correspondence analyses suggested the mutational or selection constraint on the genes to shape the codon usage.

Sarma.BACKGROUND Anaplastic thyroid carcinoma (ATC) remains one of the most challenging malignancies to treat in the modern era. Most patients present with or develop recurrent/metastatic incurable disease with poor response rates to conventional chemotherapy, and life expectancy is short. Next generation sequencing (NGS) can be leveraged in ATC to identify oncogenic alterations that can be targeted with molecularly specific therapy, offering new, effective treatment options to a subset of patients. PATIENT FINDINGS A 73-year-old man presenting with locally advanced papillary thyroid carcinoma containing a minor component of ATC was treated with surgery and iodine-131. He developed biopsy-confirmed ATC distant metastases that progressed on cytotoxic chemotherapy. NGS revealed several alterations, including a gene fusions.Pre-school children find it difficult to correctly report if it is morning or afternoon. The present study tested whether children could learn a non-verbal Time-Place Learning (TPL) task that depended on time of day. Twenty-five 4-year-olds were repeatedly asked to find a toy in one of two boxes. Children in the Cued condition were told the toy was in one box in the morning and in another box in the afternoon. Children in the Not Cued condition were told the toy was sometimes in one box and sometimes in the other box. After 80 trials, children were asked if it was morning or afternoon. About 65% of the children learned the TPL task, and about three-quarters of the children verbally identified if it was morning or afternoon. However, the children who learned the TPL task were not necessarily the children who correctly answered whether it was morning or afternoon, and those in the Cued condition were no more likely to solve the task than those in the Not Cued condition. The implication is that children have a sense of time that can be used to solve spatio-temporal contingencies, but does not depend on the verbal understanding of time of day.
