Differential modulation and non-coherent detection in wireless relay networks
… bypass the requirement of channel information, differential modulation together with non-coherent detection can be deployed. This thesis is concerned with various issues related to differential modulation and non-coherent detection in cooperative networks. Specifically, the thesis examines the …

LL-37 and citrullinated LL-37: differential modulation of the oxylipin - chemokine axis
Inflammation plays a crucial role in the host immune system, and it involves a complex network of cellular and molecular events. In the lungs, human bronchial epithelial cells release cytokines/chemokines, and other mediators such as bioactive lipids and cationic host defence peptides (CHDPs) to …

Differential modulation of T-type voltage gated calcium channels by G-protein coupled receptors.
… largely unexplored. Investigations into T-type modulation within native neuronal systems have been complicated by the presence of multiple GPCR subtypes and a lack of pharmacological tools to separate currents generated by the three T-type isoforms; Cav3.1, Cav3.2, and Cav3.3. We hypothesize …

Differential modulation of HIV-1 capsid uncoating kinetics revealed by a novel single-particle uncoating assay
… the two phases of uncoating can be modulated differentially. Binding of factors to the CANTD-CTD hexameric interface, such as PF74 and CPSF6p, accelerate or do not alter capsid opening but strongly stabilise the remaining lattice. In contrast, binding of polyanions to the central capsid pore, …

Differential MMSE: A New Approach for Adaptive Interference Suppression Over Time-Varying Channels
… noncoherent communication over such channels is differential modulation and demodulation, which obviates the need to track amplitude and phase by exploiting the fact that channel variations over successive symbols are negligible. However, there are no known methods for adaptive interference …

Monoaminergic Signaling in the Human Brain: New Insights
… emotional Stroop task and identified there were differential modulation of monoamines during the presentation of valenced words in the thalamus and anterior cingulate cortex. In a separate experiment, patients with Parkinson's disease or essential tremors played a social reward task. We observed …

Common and Distinct Neural Mechanisms of Fear Acquisition and Reversal in comorbid Autism with Social Anxiety and Social Anxiety Disorder uncomplicated by Autism
… observed, but within-group differences indicated differential modulation of the ITG in the ASD with SAD group in the Social condition compared to the Nonsocial condition. The SAD group demonstrated differential activation between conditioning stimuli in the Nonsocial condition, but not in the …

Starved State Dependent Modulation of Olfactory Receptor Neuron Function in Drosophila melanogaster larvae
… sensory neuron responses to food odorants and modulation of these responses by hunger, much less is known about the extent of modulation that exists among individual sensory neurons and its impact on driving behavioral output. We hypothesized that starvation differentially alters the …

Presenilins Modulate Cellular Activity of Ryanodine Receptors
… and presenilin 2 (PS2NTF) that resulted in differential modulation of the RyR open probability and mean Ca2+ current at the RyR single channel level. We herein tested the hypothesis that PS1NTF and PS2NTF functionally modulate RyRs in a physiologically relevant in vitro model resulting in …

Carbon Catabolite Regulation of Yersinia pestis Pathogenesis
… sources induce robust biofilm development. The differential modulation of Y. pestis biofilm production was found to be facilitated by the cAMP receptor protein, CRP. The microevolution of Y. pestis biovar Orientalis is characterized by loss of glycerol fermentation resulting from dysfunction of …
