Activation State of Human T and NK Cells Increases Sensitivity to Death by Streptococcus pneumoniae
… an infectious agent; Streptococcus pneumoniae (Spn) is the most often isolated bacteria from patients with pneumonia. When Spn undergoes cell lysis, pneumolysin (PLY) and other intracellular proteins are released. These intracellular proteins allow for Spn to acquire nutrients and to evade the …

Security of substitution-permutation network
… design called substitution-permutation network (SPN). We prove that when S-box is chosen uniformly at random as a permutation, the resulting SPN is a strong pseudorandom permutation even against an adversary having oracle access to that S-box. We then examine some special cases of SPN for a fixed …

Mechanisms of neuronal integration in adrenomedullary sympathetic preganglionic neurons.
… neurons innervating the adrenal medulla (AD-SPN) regulate the release of adrenal catecholamines into the bloodstream. This research was undertaken to investigate the intrinsic properties and synaptic pathways characteristic of AD-SPN in neonatal rat spinal cord slice preparation. The presence …

Surgical Outcomes for Solid Pseudopapillary Neoplasm of Pancreas
Background/Aims: Solid pseudopapillary neoplasm (SPN) is a rare exocrine tumor of the pancreas with low malignant potential. This study was designed to evaluate surgical outcome of solid pseudopapillary neoplasm (SPN). Methodology: From Between January 1994 to November 2013, 41 patients were …

Mechanisms and consequences of regulating neurabin and spinophilin's interaction with the tumor suppressor protein p140CAP
… two novel scaffolding proteins Spinophilin (Spn) and neurabin (Nrb) that bind to SRCIN1. They may play a role in regulating SRCIN1 activity, as well as its downstream effects that ultimately decrease SRC’s tumorigenic activity. Spn and Nrb are two scaffolding proteins that are heavily …

Characterization Of Streptolysin O As The Translocator For The Cytolysin-Mediated Translocation Process In Streptococcus Pyogenes
… e>N</underline>AD<super>+</super>-glycohydrolase: SPN) effector into the cytosol of eukaryotic host cells. Although, the fundamentals of this protein translocation process are established the details of the mechanism remain elusive. The current studies illustrate that the translocation process is …

Precise Temporal Processing in the Gerbil Auditory Brainstem
… the rodent superior paraolivary nucleus (SPN) is unknown. Two hypotheses have been tested using extracellular single cell physiology in the gerbil. The existence of binaural inputs indicates that the SPN might be involved in sound localization. Although almost half of the neurons exhibited …

The behavior of RAD51D and XRCC2 in response to drug induced DNA damage and a continuing study of the fly RAD51 paralogs
… Drosophila Rad51 paralogs (dmRad51 D, dmXRCC2, Spn B, and Spn D) and two paralogs from <em>Homo sapiens</em> (hsRad51 D and dmRad51 D) and their interactions.</p>

The effect of a vibration intervention on the somatosensory Cortex of the brain in patients with sensory peripheral Neuropathy secondary to type ii diabetes mellitus
Background: Sensory peripheral neuropathy (SPN) is one of the most common complications of type II Diabetes Mellitus (DM II) and is the most significant risk factor for ulcerations and subsequent lower limb amputations. The vibration perception threshold (VPT) in patients with sensory peripheral …

An Empirical Study on Sum-Product Networks Structure Learning and Deep Convolutional Sum-Product Networks
Sum-product Networks (SPNs) are generative probabilistic models which obtained the attention of the community for its tractability and easy methods for learning. Our rst main contribution is an empirical comparison of methods for SPN learning and inference. LearnSPN is a popular algorithm for …

Pitx3Null Mutant (Striatal Dopamine-Deficient) Mice Have Exaggerated Spiny Projection Neuron Responses to l-DOPA and D1 Agonism and Lack Baseline Striatonigral Spiking
… differences in striatal projection neuron (SPN) spike rates, SPNs <em>should </em>increase spiking during the motor response to l-DOPA. In fact, stimulating specific subsets of these neurons to spike in freely-moving wild type and parkinsonian animals causes or inhibits motor activity as …
