OBJECTIVE: Abdominal aortic aneurysm (AAA) is a life-threatening vascular pathology, the pathogenesis of which is closely related to oxidative stress. However, an effective pharmaceutical treatment is lacking because the exact cause of AAA remains unknown. Here, we aimed at delineating the role of the paraoxonases (PONs) gene cluster (PC), which prevents atherosclerosis through the detoxification of oxidized substrates, in AAA formation. APPROACH AND RESULTS: PC transgenic (Tg) mice were crossed to an Apoe(-/-) background, and an angiotensin II-induced AAA mouse model was used to analyze the effect of the PC on AAA formation...

Signal transducer and activator of transcription 3 (STAT3) protects the heart from acute ischemic stress. However, the importance of STAT3 to the heart in chronic stress, such as hypertension, is not known. To study this, we used cardiomyocyte-targeted STAT3 knockout (KO) mice and Angiotensin II (ANG II) infusion by osmotic minipumps. After 4 weeks, ANG II induced similar cardiac hypertrophy in wild type (WT) and cardiac Cre-expressing control (CTRL) mice with no impairment of cardiac function. In contrast, STAT3 KO mice exhibited reduced contractile function but similar hypertrophy to CTRL mice...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

BACKGROUND: α-Synuclein is a major component of pathologic inclusions that characterize Parkinson's disease. PRX002 is an antibody that targets α-synuclein, and its murine parent antibody 9E4 has been shown in preclinical studies to reduce α-synuclein pathology and to protect against cognitive and motor deteriorations and progressive neurodegeneration in human α-synuclein transgenic mice. METHODS: This first-in-human, randomized, double-blind, placebo-controlled, phase 1 study assessed the impact of PRX002 administered to 40 healthy participants in 5 ascending-dose cohorts (n = 8/cohort) in which participants were randomly assigned to receive a single intravenous infusion of study drug (0...

: Arresting or regressing growth of abdominal aortic aneurysms (AAAs), localized expansions of the abdominal aorta are contingent on inhibiting chronically overexpressed matrix metalloproteases (MMPs)-2 and -9 that disrupt elastic matrix within the aortic wall, concurrent with providing a stimulus to augmenting inherently poor auto-regeneration of these matrix structures. In a recent study we demonstrated that localized, controlled and sustained delivery of doxycycline (DOX; a tetracycline-based antibiotic) from poly(lactic-co-glycolic acid) nanoparticles (PLGA NPs), enhances elastic matrix deposition and MMP-inhibition at a fraction of the therapeutically effective oral dose...

BACKGROUND: Ultra-low volume (ULV) insecticidal aerosols dispensed from vehicle-mounted cold-foggers are widely considered the method of choice for control of Aedes aegypti and Ae. albopictus during outbreaks of dengue and chikungunya and, more recently, Zika. Nevertheless, their effectiveness has been poorly studied, particularly in Europe. Nearly all published studies of ULV efficacy are bio-assays based on the mortality of caged mosquitoes. In our study we preferred to monitor the direct impact of treatments on the wild mosquito populations...

BACKGROUND: Current pediatric septic shock resuscitation guidelines from the American College of Critical Care Medicine focus on the early and goal-directed administration of intravascular fluid followed by vasoactive medication infusions for persistent and fluid-refractory shock. However, accumulating adult and pediatric data suggest that excessive fluid administration is associated with worse patient outcomes and even increased risk of death. The optimal amount of intravascular fluid required in early pediatric septic shock resuscitation prior to the initiation of vasoactive support remains unanswered...

STUDY OBJECTIVE: High-dose remifentanil during surgery paradoxically increases postoperative pain intensity and morphine consumption. Cyclooxygenase inhibitors decrease prostaglandin synthesis, thereby antagonizing N-methyl-d-aspartate receptor activation, and may reduce hyperalgesia. This study was performed to evaluate whether postoperative morphine consumption increased following intraoperative continuous remifentanil infusion and whether this could be prevented by intravenous ibuprofen pretreatment...

Porphyria is caused by disorders of enzymes that synthetize porphyrins. Both elective and emergency surgical procedures on patient suffering from porphyria may provoke acute symptoms. These patients require special anesthetic management since some of commonly used anesthetic agents may also induce acute manifestation of porphyria. We present the case of 53-year-old woman previously diagnosed with porphyria who underwent elective laparoscopic cholecystectomy. Propofol-based total intravenous anesthesia with target-controlled infusion was used...

BACKGROUND: rhIGF-1/rhIGFBP-3 is being investigated for prevention of retinopathy of prematurity in extremely preterm infants. METHODS: A population pharmacokinetic model was developed using data from phase I/II (Sections A-C) trials of rhIGF-1/rhIGFBP-3 and additional studies in preterm infants to predict optimal dosing to establish/maintain serum IGF-1 within physiological intrauterine levels. In Section D of the phase II study, infants (GA [wk+d] 23+0 to 27+6) were randomized to rhIGF-1/rhIGFBP-3, administered at the model-predicted dose of 250 µg/kg/d continuous i...

Abstinent alcohol-dependent individuals experience an enduring sensitivity to cue-induced craving and relapse to drinking. There is considerable evidence indicating that structures within the midbrain and extended amygdala are involved in this process. Individually, the ventral tegmental area (VTA) and the bed nucleus of the stria terminalis (BNST) have been shown to modulate cue-induced ethanol-seeking behavior. It is hypothesized that cue-induced seeking is communicated through a direct projection from the BNST to VTA...

Mu-opioid-receptor antagonists have been extensively studied in experimental research as pharmacological tools uncovering mechanisms of pain modulation by the endogenous opioid system. In rodents, administration of high doses of mu-opioid-receptor antagonists after the resolution of an inflammatory injury has demonstrated reinstatement of nociceptive hypersensitivity indicating unmasking of latent sensitization. In a recent human study, pain hypersensitivity assessed as secondary hyperalgesia area (SHA), was reinstated 7 days after a mild thermal injury, in 4 out of 12 subjects after a naloxone infusion...

Ana Canseco-Alba, Gabriela Rodríguez-Manzo
Sexual behavior is a natural reward and the mesolimbic (MSL) system is involved in the processing of its motivational component and reinforcing properties. Endocannabinoids control rewarding behaviors through the modulation of MSL system's activity. The endocannabinoid anandamide (AEA), systemically administered, produces dose-based, biphasic effects on male rat copulation, facilitating its expression at low doses in both, sexually experienced and sexually exhausted male rats. We hypothesized that AEA's sexual facilitative effects might be exerted at the MSL circuit...

BACKGROUND: Diabetic nephropathy (DN) is a major complication of type1 and type 2 diabetes. Understanding how diabetes regulate transcriptome dynamics in DN is important for understanding the biology of the disease and for guiding development of new treatments. RESULTS: We analyzed the kidney transcriptome of a DN mouse model, D2.B6-Ins2 (Akita) /MatbJ, before/after treatment with P78-PEDF. Age, weight, and gender-matched mice and wild-type (wt) littermates were treated at 6 weeks (early treatment) or 12 weeks (late treatment) of age for the duration of 6 weeks...
