Central melanocortin signaling plays an important role in regulation of energy homeostasis by leptin and insulin. We investigated the interaction between leptin, insulin, and melanocortin-4 receptors (MC-4Rs) in the control of renal sympathetic nerve activity (RSNA) in mice. We compared the effects of intracerebroventricular (ICV) administration of leptin, insulin, MC-3/4R agonist (MTII), and c...

BACKGROUND AND STUDY AIMS Retrograde single-balloon enteroscopy (RSBE) facilitates evaluation of the distal small bowel and provision of appropriate therapy when necessary. Intubation of the terminal ileum (TI) is a major rate-limiting step, with failure rates as high as 30 %. Cap-assisted endoscopy has proven beneficial in other aspects of endoscopy. We have noticed that it similarly aids in T...

Hesperetin (Hst) is a well-known bioflavonoid, has low bioavailability. Hesperetin nanoparticles (Nano-Hst) enhance its bioavailability. Nano-Hst were not explored for their potential therapeutic activities in Alzheimer’s disease (AD). Hence, the present study was performed to evaluate the protective effect of Nano-Hst in comparison to free Hesperetin on against intracerebroventricular in...

Dietary and cerebrospinal fluid (CSF) Na(+) may act through brain amiloride-sensitive, Phe-Met-Arg-Phe-NH(2) (FMRFamide)-gated Na(+) channels (FaNaChs) to cause sympathoexcitation and hypertension. We hypothesized that FaNaChs cause sympathoexcitation via the activation of brain "ouabain" and the brain renin-angiotensin system. In conscious Wistar rats, intracerebroventricular (ICV) infusion of...

Background: Intracranial volume (ICV) is an important normalization measure used in morphometric analyses to correct for head size in studies of Alzheimer Disease (AD). Inaccurate ICV estimation could introduce bias in the outcome. The current study provides a decision aid in defining protocols for ICV estimation in patients with Alzheimer disease in terms of sampling frequencies that can be op...

We have recently reported the isolation of a novel virus, provisionally designated C/swine/Oklahoma/1334/2011 (C/OK), with 50% overall homology to human influenza C viruses (ICV), from a pig in Oklahoma. Deep RNA sequencing of C/OK virus found a matrix 1 (M1) protein expression strategy that differed from that of ICV. The novelty of C/OK virus prompted us to investigate whether C/OK virus could...

Different criteria (the drug concentration which inhibited 50% of growth [IC1/2], the lowest drug concentration at which growth was just less than 30% of that in a positive control well [IC30], the visual inhibitory concentration [ICv], and the minimum fungicidal concentration [MFC]) were applied to study the effects of some antifungal agents against Candida albicans. Amphotericin B, flucytosin...

OBJECTIVE To study the relationship between parenchymal head volume (PHV) and intracranial volume (ICV), and to compare the ability of these two measurements to reflect the association between maximum mature brain volume and late-life cognition. METHODS An elderly sample of humans with a range of cognitive functions from normality, via mild cognitive impairment (MCI) to dementia (mean age 78....

Losartan, an AT1 angiotensin II (ANG II) receptor non-peptide antagonist, induces an increase in mean arterial pressure (MAP) when injected intracerebroventricularly (icv) into rats. The present study investigated possible effector mechanisms of the increase in MAP induced by icv losartan in unanesthetized rats. Male Holtzman rats (280-300 g, N = 6/group) with a cannula implanted into the anter...

The management of oil fields that present high gas content is challenging, mainly in cases where this represents a bottleneck for production due to platform constraints. One way deal with problem the use ICVs (Interval Control Valves), which enables be controlled by zones wells. In work, we propose methodology using reactive control rules producers and ICVs, GOR as monitoring variable, improve ...
