Vip And Host Immunity
… of the current dissertation was to examine how VIP regulates host immunity and corneal healing, specifically, its control of growth factors and TLR expression in the P. aeruginosa infected cornea. Firstly, VIP treatment increased growth factor expression (EGF, GHF, FGF and VEGF) in infected …

VIP: Finding Important People in Images
People preserve memories of events such as birthdays, weddings, or vacations by capturing photos, often depicting groups of people. Invariably, some individuals in the image are more important than others given the context of the event. This work analyzes the concept of the importance of …

The role of VIP family members in diabetic retinopathy
… (PACAP) and vasoactive intestinal peptide (VIP) exert a protective effect against retinal injuries, including DR. However, until now, no study has investigated their protective role against the harmful combined effect of both hyperglycemia and hypoxia. The main objectives of this PhD thesis …

Salivary VIP concentrations are elevated in humans after acute stress
… and salivary vasoactive intestinal peptide (VIP) as stress indicators. Secondly, we questioned whether these markers help us in distinguishing between physical and psychological stress. Psychological stress can be experienced in a situation such as that in anticipation of an important exam or …

Neuroprotective effects of PACAP, VIP and NAP against hyperglycaemic retinal damage
… (PACAP), vasoactive intestinal peptide (VIP) and davunetide (NAP) are three pleiotropic related neuropeptides also expressed in the retina. Their protective role has been shown in different retinal injuries, but little is known about the relationship between these peptides and DR. The aim …

Duodenale VIP-Rezeptoren in der Dünndarmmukosa bei Kindern mit nahrungsmittelinduziertem hyperkinetischen Syndrom
… für Vasoaktives Intestinales Polypeptid (VIP), ein Neurotransmitter der „brain-gut“-Achse. Alle Patienten erfüllten die diagnostischen Kriterien des DSM IIIR und des ICD 10 für das hyperkinetische Syndrom. Zudem bestanden bei allen untersuchten Patienten rezidivierende Bauchschmerzen. Die …

Assessing knowledge-transfer in sanitation projects to promote sustainable VIP latrine provision
… can be used to support the sustainability of VIP latrines, and hence address the negative perceptions that people have of the VIP latrine. In South Africa, the basic minimum acceptable level of sanitation is a lined Ventilated Improved Pit (VIP) latrine. Some sanitation projects utilising VIP …

Einfluss der Neurotransmitter PACAP und VIP auf die Aktivität der Mitogen-aktivierten Proteinkinase in Astrozyten
PACAP und VIP sind Neuropeptide, die über mindestens drei gemeinsame Rezeptortypen agieren: PAC1, VPAC1 und VPAC2. <br>Dieser Arbeit liegen Versuche zugrunde, in denen gezeigt werden konnte, dass PACAP und VIP einen antiproliferativen Effekt auf kultivierte Astrogliazellen ausüben. Es ist bekannt, …

Suprachiasmatic nuclei development: A characterization of transcription factors and the influence of retinal innervation and VIP signaling
… retinal ganglion cell development, or functional VIP peptide or VIP receptor 2: VPAC<sub>2</sub>, Vipr2). We found that maturation of TF expression patterns within the SCN occurred independent of retinal innervation and VIP signaling, suggesting that localizations may reflect intrinsic differences …

Tertiary Phosphorus Removal Hampton Roads Sanitation District (HRSD) Virginia Initiative Plant (VIP): Technology Selection and Operational Considerations
… wastewater at its Virginia Initiative Process (VIP) facility. This change requires both improvements to existing biological treatment and the addition of advanced treatment steps to remove the remaining nutrients before discharge. To identify effective solutions, HRSD tested two different …

Nanotechnology approaches for improvoved vasoactive intestinal peptide based-drug delivery systems
… the neuropeptide vasoactive intestinal peptide (VIP). Two main questions have been addressed using VIP engineered NPs: 1. VIP functionalized gold NPs. In this case, VIP could act as a drug/diagnostic molecule for theranostic applications. 2. VIP functionalised liposomes as a targeting agent to …

The roles of vasoactive intestinal polypeptide in circadian entrainment of suprachiasmatic nucleus
… rhythms. Vasoactive intestinal polypeptide: VIP), a neuropeptide produced by SCN neurons, plays a major role in synchronizing SCN neurons to each other. Whether VIP mediates synchrony to environmental cues and how synchrony within the SCN is achieved has not been examined extensively. We …

The Effects of Vasoactive Intestinal Peptide on Adrenal Steroid Hormone Secretion
Vasoactive intestinal peptide (VIP)-immunoreactive nerve fibers have been demonstrated in the rat adrenal cortex in close association with zona glomerulosa cells (Holzwarth, 1984). We have studied the effects of VIP on steroid hormone secretion from the outer zones of the normal rat adrenal cortex. …

Regulation of Thalamic Neuron Excitability and Intrathalamic Rhythms by Vasoactive Intestinal Peptide
I found that VIP selectively increases the excitability of thalamic relay neurons by producing a long-lasting depolarization. These actions lead to antioscillatory actions of VIP on intrathalamic rhythmic activity (Chapter 2). The excitatory and antioscillatory actions of VIP are predominantly …

Caracterización y regulación del sistema receptor-efecto el péptido intestinal vasoactivo en macrófagos peritoneales de rata
La historia del péptido intestinal vasoactivo (VIP) se remonta a 1967, fecha en la que Sami Said, un nuemólogo que investigaba en Houston (Texas), descubre actividad vasoactiva, vasodilatadora, e hipotensiva en extractos acuosos de pulmón (SAID y MUTT, 1969). Pensando que esta actividad se debía a …

Molecular and Genetic Analysis of Neuropeptide Signalling in Mammalian Circadian Timekeeping
… to the periphery. Vasoactive intestinal peptide (VIP), a neuropeptide expressed in the retinorecipient ventrolateral region of the SCN, is vital to this circuit-level co-ordination by signalling to its cognate VPAC2 receptor. In addition, VIP is important for the integration of light input into …

MADD MESSAGE EFFECTS: A TWELVE-YEAR RANDOMIZED TRIAL
… MADD (Mothers Against Drunk Drivers) created VIPs (Victim Impact Panels) where victims impact offenders with gory stories, photos, and threats of punishments and loss of freedom, hoping this message will deter DWIs. It is remarkable that although the VIP message is considered a primary DWI …

Regulation of Neuropeptide Y, Vasoactive Intestinal Polypeptide, and Their Receptors in Trigeminal Ganglion Neurons and Glia in Response to Adjuvant-Induced Inflammation
… Y (NPY), vasoactive intestinal polypeptide (VIP), and their receptors have been implicated in the underlying pathology of temporomandibular joint disorders. The goal of this study was to investigate activation of NPY, VIP, and their receptors in a model of TMJ inflammation using …
