Unexpected Populations for Deep Vein Thrombosis: Presentation in an Endurance Athlete.

This case presents an athletic 40-year-old female marathon runner who presented with a headache secondary to dural venous sinus thrombosis and right calf deep vein thrombosis (DVT). Though this is outside of the typical image we portray of a common DVT patient, athletes too experience hypercoagulable risk factors and medical issues, just as their less in-shape peers. This patient's history of oral contraceptive use, Lynch syndrome, colon cancer, and pregnancy indicates potential risk factors for DVT.

Escalation of an Otherwise Curable Cancer: Retroperitoneal Mass Destruction Associated With Testicular Seminoma in a Psychiatric Patient.

We report the case of a 31-year-old male patient with underlying psychiatric illness and substance abuse who presented to the emergency department with a chief complaint of abdominal pain. CT scan of the abdomen revealed a large retroperitoneal mass wrapping around the aorta and obstructing the left ureter causing hydronephrosis. Physical examination found a painless left testicular mass.

Adults blink more deeply: a comparative study of the attentional blink across different age groups.

The attentional blink (AB) is thought to help the visual system parse and categorize rapidly changing information by segmenting it into temporal chunks, and is elicited using Rapid Serial Visual Presentation. It is reflected in a decrease in accuracy at detecting the second of two targets presented within 200-500 ms of the first, and its development appears to be protracted on tasks that require set-shifting. Here, younger (M = 8.

Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults.

Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation.

Plant science. Genomic-scale exchange of mRNA between a parasitic plant and its hosts.

Movement of RNAs between cells of a single plant is well documented, but cross-species RNA transfer is largely unexplored. Cuscuta pentagona (dodder) is a parasitic plant that forms symplastic connections with its hosts and takes up host messenger RNAs (mRNAs). We sequenced transcriptomes of Cuscuta growing on Arabidopsis and tomato hosts to characterize mRNA transfer between species and found that mRNAs move in high numbers and in a bidirectional manner.

Quantification of tomato and Arabidopsis mobile RNAs trafficking into the parasitic plant Cuscuta pentagona.

The cross-species movement of mRNA from hosts to the parasitic plant Cuscuta pentagona has been reported previously, but has not been characterized quantitatively or with attention to uptake patterns and the fate of specific mRNAs. Real-time PCR and RNA-Seq approaches were used to identify and characterize mobile transcripts from tomato and Arabidopsis hosts into C. pentagona.

Optoperforation of single, intact Arabidopsis cells for uptake of extracellular dye-conjugated dextran.

A plant science research goal is to manipulate single cells in an intact organism in order to study their interactions with neighboring cells. Based on a technique previously demonstrated in isolated plant cells, mammalian cells and cyanobacteria, Arabidopsis epidermal cells were optoperforated to allow for uptake of external cascade blue-labeled dextrans. Adverse organelle responses were determined to be minimal and dye retention was demonstrated for at least 72 hours.

RNA trafficking in parasitic plant systems.

RNA trafficking in plants contributes to local and long-distance coordination of plant development and response to the environment. However, investigations of mobile RNA identity and function are hindered by the inherent difficulty of tracing a given molecule of RNA from its cell of origin to its destination. Several methods have been used to address this problem, but all are limited to some extent by constraints associated with accurately sampling phloem sap or detecting trafficked RNA.
