Attentional control in patients with temporal lobe epilepsy
Across different studies, patients with temporal lobe epilepsy (TLE) demonstrate
impairments on numerous measures of attentional control that are classically associated
with frontal lobe functioning. One aspect of attentional control that has not been
examined in TLE is the ability to execute two modality-specific tasks concurrently. We sought to examine the status of dual-task coordination in TLE. We further examined the cohorts’ performance on a range of traditional measures of attentional control. Eighteen
TLE patients and 22 healthy controls participated in the study. Dual-task performance
involved comparing the capacity to execute a tracking and a digit recall task simultaneously with the capacity to execute the tasks separately. We also administered measures of: set
shifting (odd-man-out test), sustained attention (elevator counting), selective attention
(elevator counting with distraction), and divided attention (trail making test). We found that the proportional decrement in dual-task performance relative to single-task performance did not vary between the groups (TLE = 92.48%; controls = 93.70%), nor
was there a significant difference in sustained attention (p > .10). Patients with TLE did demonstrate marked deficits in selective attention (p < .0001), divided attention
(p < .01), and set shifting (p < .01). These findings add to the knowledge about cognitive
dysfunction in TLE, indicating that impairments in attentional control in TLE tend to be
selective. The greatest deficits appear to be on tasks that invoke a high level of processing resources. In contrast, sustained attention is less compromised and the capacity to allocate cognitive resources appears to be normal in patients with TLE

Targeting mutant fibroblast growth factor receptors in cancer
Fibroblast growth factor receptors (FGFRs) play diverse roles in the control of cell proliferation, cell differentiation, angiogenesis and development. Activating the mutations of FGFRs in the germline has long been known to cause a variety of skeletal developmental disorders, but it is only recently that a similar spectrum of somatic FGFR mutations has been associated with human cancers. Many of these somatic mutations are gain-of-function and oncogenic and create dependencies in tumor cell lines harboring such mutations. A combination of knockdown studies and pharmaceutical inhibition in preclinical models has further substantiated genomically altered FGFR as a therapeutic target in cancer, and the oncology community is responding with clinical trials evaluating multikinase inhibitors with anti-FGFR activity and a new generation of specific pan-FGFR inhibitors
Measures of short-term memory: A historical review
Following Ebbinghaus (1885/1964), a number of procedures have been devised to measure short-term memory using immediate serial recall: digit span, Knox's (1913) cube imitation test and Corsi's (1972) blocks task. Understanding the cognitive processes involved in these tasks was obstructed initially by the lack of a coherent concept of short-term memory and later by the mistaken assumption that short-term and long-term memory reflected distinct processes as well as different kinds of experimental task. Despite its apparent conceptual simplicity, a variety of cognitive mechanisms are responsible for short-term memory, and contemporary theories of working memory have helped to clarify these. Contrary to the earliest writings on the subject, measures of short-term memory do not provide a simple measure of mental capacity, but they do provide a way of understanding some of the key mechanisms underlying human cognition
