Non-destructive subsurface detection of encapsulated, coated, or seal-packaged foods and pharmaceuticals can help prevent distribution and consumption of counterfeit or hazardous products. This study used a Spatially Offset Raman Spectroscopy (SORS) method to detect and identify urea, ibuprofen, and acetaminophen powders contained within one or more (up to eight) layers of gelatin capsules to demonstrate subsurface chemical detection and identification. A 785-nm point-scan Raman spectroscopy system was used to acquire spatially offset Raman spectra for an offset range of 0 to 10 mm from the surfaces of 24 encapsulated samples, using a step size of 0...

Parenteral beta-blocker therapy via continuous infusion has shown promising results for improved outcomes for patients with septic shock. As patients with septic shock may require multiple intravenous medications, compatibility is necessary to co-infuse these medications through a y-site connector. The purpose of this study was to examine the physical compatibility of select intravenous drugs used for patients with septic shock combined with various intravenous beta-blockers including esmolol, labetalol, and metoprolol through a simulated y-site infusion...

RATIONALE: We have reported that levetiracetam, a novel anticonvulsant with analgesic properties, synergizes with ibuprofen/aspirin/paracetamol in a model of diabetic painful neuropathy (DPN). Most guidelines recommend gabapentin, pregabalin, and duloxetine as first- or second-line agents for DPN. OBJECTIVE: We examined the effects of combination treatment of first-/second-line analgesics with levetiracetam in a model of DPN. Additionally, the levetiracetam's combinations with antioxidants, low dose of aspirin, coenzyme Q10, or α-lipoic acid were evaluated...

Idiopathic carotidynia is a syndrome characterized by pain and tenderness over the carotid artery without an associated structural luminal abnormality. Controversy exists over whether this is a distinct disease entity or merely a symptom attributable to other causes of neck pain, such as carotid dissection or vasculitis. A 50-year-old woman presented with sudden-onset right neck pain. Imaging studies demonstrated transmural inflammation of the proximal internal carotid artery, without evidence of intraluminal pathology...

BACKGROUND: Post-tonsillectomy pain is 1 of the most intense postoperative pain conditions. However, optimal and sufficient postoperative analgesic treatment remains unclear. We investigated the effect of topical ropivacaine for post-tonsillectomy pain in 160 adult outpatient surgery patients over 2 postoperative weeks. METHODS: At the end of tonsillectomy, 2 swabs soaked in either 1% ropivacaine or saline were packed into the tonsillar beds for 5 minutes. We used ibuprofen and a combination of acetaminophen (500 mg)-codeine (30 mg) tablets as postoperative analgesics for 2 weeks...

Geranyl flavones have been studied as compounds that potentially can be developed as anti-inflammatory agents. A series of natural geranylated flavanones was isolated from Paulownia tomentosa fruits, and these compounds were studied for their anti-inflammatory activity and possible mechanism of action. Two new compounds were characterized [paulownione C (17) and tomentodiplacone O (20)], and all of the isolated derivatives were assayed for their ability to inhibit cyclooxygenases (COX-1 and COX-2) and 5-lipoxygenase (5-LOX)...

INTRODUCTION: Ibuprofen sodium dihydrate, a new formulation of ibuprofen, was introduced with the claim of faster onset of analgesia. Most of the data on this new ibuprofen formulation are drawn from studies using the oral surgery model. Because this model differs significantly from the endodontic pain model, we conducted a study comparing ibuprofen sodium dihydrate with conventional ibuprofen acid in endodontic pain patients. METHODS: This randomized, double-masked study recruited subjects experiencing moderate to severe pain from a tooth diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis (n = 41)...

Periodic mesoporous organosilicas (PMOs) nanospheres with tubular structure were prepared with compressed CO2 using cationic and anionic mixed surfactant (CTAB/SDS) and triblock copolymer Pluronic P123 as bi-templates. TEM, N2 adsorption-desorption, solid NMR, and FTIR were employed to characterize the obtained materials. Compressed CO2 severed as acidic reagent to promote the hydrolysis of organosilicas, and could tune the morphology and structure of the obtained PMOs nanomaterials simple by adjusting the CO2 pressure during the synthesis process...

When using lipid nanoparticles as drug carrier system it is important to know how much drug can be loaded to the nanoparticles. The mainly used drug loading procedure is an empirical approach dissolving the drug in the liquid lipid during preparation of the nanoparticles. This approach does not necessarily lead to the truly loadable amount, as the lipid can, e.g. be overloaded, in particular when it is processed in the heat. In this work, a different procedure, passive drug loading, was evaluated to determine the drug loading capacity of various lipid nanoparticles (supercooled trimyristin emulsion droplets, solid trimyristin nanoparticles, tristearin nanoparticles in the α-modification and cholesteryl myristate nanoparticles in the supercooled smectic as well as in the crystalline state)...

Many drugs with unknown safety profiles are administered to pregnant women, placing their offspring at risk. I assessed whether behavioral outcomes for children exposed during gestation to antidepressants, anxiolytics, anti-seizure, anti-nausea and sedative medications can be predicted by more extensive animal studies than are part of the FDA approval process. Human plus rodent data were available for only 8 of 33 CNS-active drugs examined. Similar behavioral and cognitive deficits, including autism and ADHD emerged in human offspring and in animal models of these disorders after exposure to fluoxetine, valproic acid, carbamazepine, phenytoin, phenobarbital, acetaminophen and ibuprofen...

Hydroxyl radical ((•)OH) and sulfate radical anion (SO4(•-)) based advanced oxidation technologies (AOTs) are effective methods to treat trace organic contaminants (TrOCs) in engineered waters. Although both technologies result in the same overall removal of TrOCs, the mechanistic differences between these two radicals involved in the oxidation of TrOCs remain unclear. In this study, we experimentally examined the degradation kinetics of neutral ibuprofen (IBU), a representative TrOC, by (•)OH and SO4(•-) at pH3 in UV/H2O2 and UV/persulfate systems, respectively...

Sequence-defined chiral polyimides comprising identical asymmetric diamine monomers arranged in different directions along the main chain were designed and prepared. These new sequence-defined polymers exhibit sequence-dependent self-assembly behaviors and responses to ibuprofen enantiomers, as revealed by their chiroptical spectra and gelation properties. For the first time, the self-assembly of polymers and their interactions with guest molecules have been successfully controlled by means of the directional arrangement of the monomers in their polymer backbones...

Emerging contaminants including pharmaceuticals are a class of compounds that are causing great concern due to several environmental problems. Conventional water and wastewater treatments do not achieve high removal efficiencies for many of these drugs. Therefore, the present work investigated the removal of ibuprofen (IBP) by heterogeneous photocatalysis using TiO2 irradiated with artificial UV light or solar radiation. The treated solutions were tested against Daphnia similis and Raphidocelis subcapitata, which are species commonly used as bioindicators of environmental conditions...

BACKGROUND: Low-dose aspirin irreversibly inhibits platelet cyclooxygenase-1 (COX-1) and suppresses platelet aggregation. It is effective for secondary prevention of cardiovascular events. Because nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly bind with COX-1, the antiplatelet effects of aspirin may be suppressed when NSAIDs are co-administered. This interaction could be avoided by avoiding simultaneous administration; however, the minimum interval that should separate the administration of aspirin and loxoprofen is not well known...
