For inhalational studies and aerosol exposures to viruses, head-out plethysmography acquisition has been traditionally used for the determination of estimated inhaled dose in anesthetized nonhuman primates prior to or during an aerosol exposure. A pressure drop across a pneumotachograph is measured within a sealed chamber during inspiration/exhalation of the nonhuman primate, generating respiratory values and breathing frequencies. Due to the fluctuation of depth of anesthesia, pre-exposure respiratory values can be variable, leading to less precise and accurate dosing calculations downstream...

Apomorphine infusion or injection is an important dopamine agonist non-oral therapy usually used in advanced Parkinson's disease (PD) with refractory motor fluctuations. The drug also has appreciable efficacy for nonmotor fluctuations and is the quickest to reverse predictable "off" periods. Current subcutaneous administration, however, is complicated by problems associated with needle-based therapies, such as skin nodule formation, skin irritation, and avoidance of this treatment option by needle-phobic subjects...

BACKGROUND: Critical care patients are at increased risk of infection. Near-patient surfaces act as reservoirs of microbial soil, which may contain pathogens. AIM: To correlate soil levels with hand-touch frequency of near-patient sites in an intensive care unit (ICU). METHODS: Five sites around each bed in a 10-bed ICU were screened for total microbial soil (cfu/cm(2)) and Staphylococcus aureus every month for 10 months. Selected sites were infusion pump and cardiac monitor, left and right bedrails, and bed table...

Diabetes, rare in the neonatal period, should be evoked in every newborn presenting with unexplained intrauterine and early postnatal growth retardation. This case report illustrates the clinical course and therapeutic approach of a newborn diagnosed with transient diabetes. The baby was born at 37 weeks of gestation with a severe intrauterine growth restriction. Except a mild macroglossia and signs of growth restriction, physical examination was normal. On the fifth day of life, hyperglycemia (180 mg/dl) was noted, and the next day, the diagnosis of diabetes was confirmed (high blood sugar, glucosuria, undetectable levels of insulin and C-peptide)...

A 67-year critically ill patient suffered from a hypertensive crisis (200 mm Hg) because of a norepinephrine overdose. The overdose occurred when the clinician exchanged an almost-empty syringe and the syringe pump repeatedly reported an error. We hypothesized that an object between the plunger and the syringe driver may have caused the exertion of too much force on the syringe. Testing this hypothesis in vitro showed significant peak dosing errors (up to +572%) but moderate overdose (0.07 mL, +225%) if a clamp was used on the intravenous infusion line and a large overdose (0...

INTRODUCTION: When oral or transdermal drug therapy in Parkinson's disease becomes less effective, there are three therapies using assisted devices that can reduce motor and non-motor complications: subcutaneous apomorphine infusion pump (SAIP), continuous levodopa/carbidopa duodenal infusion (LDI) and deep brain stimulation (DBS). AIM: Conduct a comparative pharmacoeconomic analysis of the use of SAIP, with LDI and DBS. As a secondary objective arises discuss the profile of the ideal candidate for each of the technicals...

This study examined the long-term efficacy of insulin pump therapy for type 1 diabetes patients when performed using carbohydrate counting with bolus calculators for one year. Twenty-two type 1 diabetes patients who had just started continuous subcutaneous insulin infusion were examined and divided into 2 groups: one that was educated about carbohydrate counting using bolus calculators (n=14) and another that did not use bolus calculators (n=8). After one year, the hemoglobin A1c levels of the patient group that used bolus calculators decreased persistently and significantly (P=0...

Intraocular injection has become an increasingly important intervention in the treatment of posterior segment diseases. However, an acute intraocular pressure (IOP) elevation after intravitreal injection is a common concern. This study aimed to evaluate the efficacy of intravitreal infusion in maintaining stable IOP in a rabbit model. Trypan blue (TB) 0.06% with an external pump was used to evaluate intravitreal infusion in rabbit eyes. Groups A (50 μL), B (100 μL), C (150 μL), and D (200 μL) were slowly infused over 30 minutes with TB...

PURPOSE: Inadequate analgesia following abdominal surgery may affect outcome. Data in patients undergoing liver surgery suggested that postoperative coagulopathy might delay epidural catheter removal. Thus, alternative analgesic techniques should be evaluated. METHODS: We compared the analgesic efficacy of intraoperative intrathecal morphine [single injection 4 µg/kg before skin incision (ITM group, n = 23)] to intravenous opioids [iv remifentanil infusion during surgery followed by i...

OBJECTIVES: FDA approval of proton-pump inhibitors for infantile GERD has been limited by intra-patient variability in the clinical assessment of GERD. For children 1-17 years old, extrapolating efficacy from adults for IV esomeprazole was accepted. The oral formulation was previously approved in children. Exposure-response and exposure matching analyses were sought to identify approvable pediatric doses. METHODS: Intragastric pH biomarker comparisons between children and adults were conducted...

Nicotinic acid (NiAc) is a potent inhibitor of lipolysis, acutely reducing plasma free fatty acid (FFA) concentrations. However, a major FFA rebound is seen during rapid NiAc washout and sustained exposure is associated with tolerance development, with FFA returning to pretreatment levels. Our aim was to find a rational NiAc dosing regimen which preserves FFA lowering, sufficient to reverse non-adipose tissue lipid accumulation and improve metabolic control, in obese Zucker rats. We compared feeding-period vs...

RATIONAL: Pressure overload induces adaptive and maladaptive cardiac remodeling processes in the heart. Part of the maladaptive process is the cross-talk between cardiomyocytes and macrophages which is dependent on the function of the Activating Transcription Factor 3, ATF3. Yet, the molecular mechanism involved in cardiomyocytes-macrophages communication leading to macrophages recruitment to the heart and cardiac maladaptive remodeling is currently unknown. METHODS AND RESULTS: Isolated peritoneal macrophages from either wild type or ATF3-KO mice were cultured in serum free medium to collect conditioned medium (CM)...

The Na(+) -ATPase, a secondary pump in the proximal tubule, is only weakly responsive to angiotensin II in adult offspring exposed perinatally to high Na(+) intake. We have investigated whether the offspring from mothers given 0.3 M NaCl show an ineffective angiotensin II action to increase in blood pressure. It was hypothesized that functional alterations at adult life are associated with the number angiotensin II-positive cells in the developing kidney, with increased oxidative stress in maternal/foetal organs, or with morphometrical changes in placentas...

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...

Reduced cerebrospinal fluid (CSF) production and increased resistance to CSF outflow are considered to be associated with aging, and are also characteristics of Alzheimer's disease (AD). These changes probably result in a decrease in the efficiency of the mechanism by which CSF removes toxic molecules such as amyloid-β (Aβ) and tau from the interstitial fluid space. Soluble Aβ is potently neurotoxic and dysfunctional in CSF circulation and can accelerate the progression of AD. Current therapies for AD exhibit poor efficiency; therefore, a surgical method to improve the homeostasis of CSF is worthy of investigation...

Intra-cerebrospinal fluid (CSF) injection of recombinant human lysosomal enzyme is a potential treatment strategy for several neurodegenerative lysosomal storage disorders including Sanfilippo syndrome (Mucopolysaccharidosis type IIIA; MPS IIIA). Here we have utilised the MPS IIIA Huntaway dog model to compare the effectiveness of the repeated intermittent bolus injection strategy being used in the trials with an alternate approach; slow, continual infusion of replacement enzyme (recombinant human sulphamidase; rhSGSH) into the spinal CSF using a SynchroMed II® pump attached to a spinal infusion cannula...

BACKGROUND: In this study the effects of a new, highly selective sodium-calcium exchanger (NCX) inhibitor, ORM-10962 were investigated on cardiac NCX current, Ca2+ transients, cell shortening and in experimental arrhythmias. The level of selectivity of the novel inhibitor on several major transmembrane ion currents (L-type Ca2+ current, major repolarizing K+ currents, late Na+ current, Na+/K+ pump current) was also determined. METHODS: Ion currents in single dog ventricular cells (cardiac myocytes; CM), and action potentials in dog cardiac multicellular preparations were recorded utilizing the whole-cell patch clamp and standard microelectrode techniques, respectively...
