Characterization of an AAC-11-derived anticancer peptide
AAC-11 is an anti-apoptotic protein that is upregulated in most cancer cells. Increased expression of AAC-11 confers a survival advantage when cancer cells are challenged with various stresses and contributes to tumor invasion and metastases whereas its deregulation reduces resistance to chemotherapeutic drugs. The antiapoptotic effect of AAC-11 may be clinically relevant as its expression correlates with poor prognosis in several human cancers. Thus, inactivation of AAC-11 might constitute an attractive approach for developing cancer therapeutics. We have developed an AAC-11-deri... περισσότερα »

Clathrin regulates lymphocyte migration by driving actin accumulation at the cellular leading edge
[image: cover.gif?v=1&s=a7ea901f55e135f2a892ad12] Lymphocyte migration, which is essential for effective immune responses, belongs to the so-called amoeboid migration. The lymphocyte migration is up to 100 times faster than between mesenchymal and epithelial cell types. Migrating lymphocytes are highly polarized in three well-defined structural and functional zones: uropod, medial zone and leading edge. The actiomyosin-dependent driving force moves forward the uropod, whereas massive actin rearrangements protruding the cell membrane are observed at the leading edge. These actin re... περισσότερα »

BOIN: A Simple, Well-Performing Bayesian Phase I Design
Alexandros G. SfakianakisστοSquamous cell carcinoma (SCC) - Cancer - MelanomaΠριν από 25 δευτερόλεπτα
Despite more than two decades of publications that offer more innovative model-based designs, the classical 3+3 design remains the most dominant phase I trial design in practice. In this article, we introduce a new trial design, the Bayesian optimal interval (BOIN) design. The BOIN design is easy to implement in a way similar to the 3+3 design, but is more flexible for choosing the target toxicity rate and cohort size and yields a substantially better performance that is comparable to that of more complex model-based designs. The BOIN design contains the 3+3 design and the acceler... περισσότερα »

Voltage imaging to understand connections and functions of neuronal circuits
Understanding of the cellular mechanisms underlying brain functions such as cognition and emotions requires monitoring of membrane voltage at the cellular, circuit, and system levels. Seminal voltage-sensitive dye and calcium-sensitive dye imaging studies have demonstrated parallel detection of electrical activity across populations of interconnected neurons in a variety of preparations. A game-changing advance made in recent years has been the conceptualization and development of optogenetic tools, including genetically encoded indicators of voltage (GEVIs) or calcium (GECIs) and ... περισσότερα »
Physiological modulators of Kv3.1 channels adjust firing patterns of auditory brain stem neurons
Many rapidly firing neurons, including those in the medial nucleus of the trapezoid body (MNTB) in the auditory brain stem, express "high threshold" voltage-gated Kv3.1 potassium channels that activate only at positive potentials and are required for stimuli to generate rapid trains of actions potentials. We now describe the actions of two imidazolidinedione derivatives, AUT1 and AUT2, which modulate Kv3.1 channels. Using Chinese hamster ovary cells stably expressing rat Kv3.1 channels, we found that lower concentrations of these compounds shift the voltage of activation of Kv3.1 ... περισσότερα »
Frequency-specific insight into short-term memory capacity
The digit span is one of the most widely used memory tests in clinical and experimental neuropsychology for reliably measuring short-term memory capacity. In the forward version, sequences of digits of increasing length have to be reproduced in the order in which they are presented, whereas in the backward version items must be reproduced in the reversed order. Here, we assessed whether transcranial alternating current stimulation (tACS) increases the memory span for digits of young and midlife adults.
