Previous studies have shown that equine SAA is more stable at room temperature than refrigerated. A small study at Cornell University confirmed this finding. Two equine samples with high values of 481 and 177 ug/ml showed a 2-3% decrease in concentration at 4ºC with storage for 24 hours versus a 3-5% decrease at room temperature. With storage for 72 hours, the drop at 4ºC was greater than at room temperature (7% versus 3-6% at 48 hours and 8-9% versus 2-4% at 72 hours). Very high values (,60 ug/dL) were still abnormal after 10 days of storage at either temperature (Hillstrom et al 2010). SAA concentrations are stable frozen (-20ºC), thus it is recommended that for storage ,24 hours, the samples should be frozen and shipped ensuring that they remain frozen. If freezing is not an option, then the samples should be maintained at room temperature. This also suggests that mildly increased concentrations may drop to within reference intervals (,20 ug/mL in horses) with storage. Stability is unknown ...

OPAT is used for treating a wide range of infections, including skin and soft tissue infections, osteoarticular infections, bacteraemia, endocarditis and complex intra-abdominal and urinary tract infections, even in presence of multiresistant microorganisms. Correct choice of antimicrobial agent and adequate patient selection are crucial for reaching therapeutic success and avoiding readmissions, treatment prolongation or treatment-related toxicity. The optimal antimicrobial for OPAT must be highly effective, have a long half-life and an adequate spectrum of action. Ceftriaxone and teicoplanin are currently the most prescribed antibiotics for OPAT, though daptomycin and ertapenem are also on the rise, due to their high efficiency, safety and wide spectrum of action. Antibiotics that are stable at room temperature can be administered through a continuous perfusion, though self-administration is preferable although it requires training of the patient or the caregiver. Factors that are most ...

Louis Roux from LifeAssay Diagnostics (Pty) Ltd. in South Africa, in collaboration with PATH, will develop an easy-to-use, low-cost, strip test for pregnant women in developing countries to detect the onset of proteinuria, which indicates a highly increased risk of preeclampsia/eclampsia. Preeclampsia/eclampsia is a major cause of maternal death, particularly in developing countries. Onset is rapid, and so early diagnosis is crucial, particularly in remote communities where health care is not immediately available. The test measures the ratio of protein to creatinine, which is more accurate than the current protein-only version, and they will produce a low-cost version that can be locally manufactured. They will evaluate the tests performance in comparison to three similar tools on a minimum of 1100 urine samples collected from the CAP trial in South Africa. The study also includes usability and stability evaluations to inform further prototype improvements and product insert development for ...

It is known that membrane technologies may have a major role to play in the development of environmental-friendly processes, either in gas or liquid separations. In liquid separations, one of the challenging issues is to get membranes with suitable separation properties able also to survive to the exposure of liquid solvents at various temperatures. Aromatic polyimides are known to exhibit a very good stability to a great number of solvents, but their permeability are low because of their rigid carbon skeleton and of their low available free volume; so their uses are mainly limited to gas separations or to filtration processes (MF, UF). To broaden the application area of polyimides in liquid separations, we have prepared and studied the properties of a block ether aromatic copolyimide series where the ether soft block acts both as a selective and a permeable block; we describe attempts to get asymmetric polyetherimide (PEI) membranes having molecular separation properties using various experimental

A sensitive, accurate, precise, and stability-indicating high-performance thin-layer chromatographic method has been established and validated for analysis of etoricoxib in both bulk drug and formulations. Chromatography is performed on aluminum-backed silica gel 60F254 plates with toluene-1,4-dioxane-methanol 8.5:1.0:0.5 (v/v) as mobile phase. This system furnished compact bands for etoricoxib (R F 0.24). Rofecoxib (RF 0.38) was used as internal standard. Densitometric analysis of etoricoxib was performed in absorbance mode at 235 nm. Linear regression data for the calibration plots showed there was a good linear relationship between response and amount of etoricoxib in the range 100-1500 ng per band; the correlation coefficient was 0.9922 ± 0.001. The mean values of the slope and intercept of the plot were 280.14 ± 0.26 and 320.01 ± 0.22, respectively. The method was validated for precision, accuracy, ruggedness, and recovery. The limits of detection and quantitation were 30 and 100 ng per ...
In the article below, Jie Ding, associate director of development and validation at the PPD® Laboratories GMP lab, discusses liquid chromatography-mass spectrometry in drug discovery and development.. In a drug stability program, high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection remains the most common and cost-effective methodology. Even so, UV detection has its own limitations, including poor sensitivity for non-UV absorbing compounds and lack of specificity. These shortcomings in turn have motivated scientists to pursue other alternatives. Mass spectrometry detection is such a candidate. Mass spectrometry (MS) is a detection method that measures the mass-to-charge ratio (m/z) of a compound. Compared to UV detection, MS offers higher sensitivity, better detection limits, and the ability to provide additional molecular weight information-making it an information rich detection method.. Over the last two decades, MS has become an important analytical tool to ...
Abstract Present study aimed to develop a microemulsion system for topical application of Amoxicillin to provide various advantages over conventional dosage forms. Amoxicillin is broad-spectrum semisynthetic antibiotic similar to ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration. Amoxicillin is commonly prescribed with clavulanic acid (a beta-lactamase inhibitor) as it is susceptible to beta-lactamase degradation. Clinical studies show that it is highly effective for topical treatment of skin infections. The microemulsion was prepared using oleic acid as an oil phase, tween 20 as surfactant and propylene glycol as co-surfactant. The drug was evaluated for their micropolitical properties like the angle of repose, bulk density; tapped density, Carrs index, and Hausners ratio were studied. In-vitro characterization of the microemulsion of amoxicillin was done through measurement of pH, conductivity, viscosity, drug stability.. ...

Antibacterial tests showed that the surface with AgNPs reduced the number of the bacteria. However, to be used in long-term industrial applications, the surfaces are required to have sufficient chemical stability in the operation environment. This is why the stability of the produced surfaces was studied as a function of pH value of the solution. According the results, the produced surfaces are stable in neutral environments but release silver ions at high rates and dissolve or ...

<i>Background:</i> To ensure the successful treatment of infectious disease using antimicrobial therapy, a sufficient concentration of the stable, active drug is required at the site of infection. For the achievement of this with respect to the ß-lactam group of antibiotics, of which amoxicillin is a member, the presence of an intact ß-lactam ring is essential. Destruction of this sensitive ring can lead to the ingestion of an inactive drug. This can contribute to treatment failure and antibiotic resistance. Thus, the aims of this study were to determine whether the types of packaging in which amoxicillin preparations are dispensed and the temperature and humidity conditions under which they are stored by patients are adequate and appropriate to ensure drug stability. <br><i>Methods:</i> A mini-survey of pharmacies and patients was conducted in order to determine the types of packaging in which amoxicillin preparations are

Parenteral nutrition (PN) provides intravenous nutritional support to patients with reduced gastrointestinal function. A PN bag comprises the basic building blocks of the food groups: lipids, glucose, amino acids, vitamins, electrolytes and trace elements. Recently there has been an increase in demand for extended storage periods for PN bags, to ease management of an increasing home care market. Prior to a PN formulation being deemed safe for a patient, a laboratory simulation is carried out on the proposed admixture under the requested storage and administration conditions. Currently only the physical stability is assessed; physical testing provides no information on the quantity of each component remaining in the bag after storage. Consequently, there is a need for assessing the chemical stability of PN to indicate the quantity of each component that remains in the PN bag. A commonly used amino acid product, Aminoven® 25, contains 16 amino acids; this work aimed to develop a HPLC assay ...

Results: The retention time was observed at 2.718 min. The system suitability results were found to be within limits. The method was precise, with lower than 2 %RSD and the calibration curve was linear (r2=1) over a concentration range of 2.5-160 µg/ml. The detection and quantification limit was found to be 0.045 µg/ml and 0.15 µg/ml, respectively. Recovery of the drug was found between 100.09-100.19%. The assay of ropinirole hydrochloride in ROPITOR® and ROPARK® tablets were found to be 100.4 and 103.60 %, respectively. The forced degradation studies were carried out to demonstrate the specificity of the method by exposing the API under conditions of hydrolysis, oxidation, thermal and photolytic as per ICH Q1A(R2) guidelines. ...
The October 2012 Global Financial Stability Report (GFSR) finds increased risks to the global financial system, with the euro area crisis the principal source of concern, and urges policymakers to act now to restore confidence, reverse capital flight, and reintegrate the euro zone. This GFSR presents a report on whether regulatory reforms are moving the financial system in the right direction, and finds that progress has been limited, partly because many reforms are in the early stages of implementation and partly because crisis intervention methods are still in use in a number of economies, delaying the movement of the financial system onto a safer path. The final chapter examines whether certain aspects of financial structure enhance economic outcomes. Indeed, some structural features are associated with better outcomes. In particular, financial buffers made up of high-quality capital and truly liquid assets tend to be associated with better economic performance.
Summary:. This paper presents an assessment of financial system stability in the Netherlands. The country is home to a global systemically important bank and a global systemically important insurer. The banking system comprises half of the financial sector and is concentrated in four domestic banks. Major reforms, driven by the European Union and global developments, have significantly strengthened financial sector oversight. The authorities response to the global financial crisis was far-reaching and addressed many deficiencies. The Single Supervisory Mechanism has enhanced bank supervision, as have strengthened capital and liquidity regulations. Insurance supervision is also stricter thanks to Solvency II, and there is a new framework for the pension sector.. ...
This paper discusses key findings of the Financial System Stability Assessment for Namibia, including the Report on the Observance of Standards and Codes on Banking Supervision. The financial system of Namibia appears healthy, well-run, and resilient to plausible macroeconomic shocks. Namibia has one of the most sophisticated and highly developed financial systems in Africa. It comprises a diverse range of institutions, which are mostly private. The banking sector is mature, profitable, and well capitalized. The nonbank financial institutions sector is also well developed.
The main goal of this work was to develop an optimal self-microemulsifying paclitaxel prepared with PLGA and solubilizer such as tetraglycol, Cremophor ELP, and Labrasol. The prepared PTx-loaded SMES showed the size of the range of 80-130 nm by dy-namic light scattering and a spherical shape by atomic force microscopy. In experiment of storage stability in deionized water (DW) or blood condition, PTx-loaded SMES showed good stability in DW and comparable stability in blood condition at 37oC for 7 days. In addition, PTx-loaded SMES showed a sig-nificant inhibitory effect on B16F10 melanoma proli-feration. In conclusion, we confirmed that the for-mulations tried in this study could be used as admin-istration form for animal trials of PTx.

Adequate aqueous solubility has been one of the desired properties while selecting drug molecules and other bio-actives for product development. Often solubility of a drug determines its pharmaceutical and therapeutic performance. Majority of newly synthesized drug molecules fail or are rejected during the early phases of drug discovery and development due to their limited solubility. Sufficient permeability, aqueous solubility and physicochemical stability of the drug are important for achieving adequate bioavailability and therapeutic outcome. A number of different approaches including co-solvency, micellar solubilization, micronization, pH adjustment, chemical modification, and solid dispersion have been explored towards improving the solubility of various poorly aqueous-soluble drugs. Dendrimers, a new class of polymers, possess great potential for drug solubility improvement, by virtue of their unique properties. These hyper-branched, mono-dispersed molecules have the distinct ability to bind the

On your initial visit to Tancredi Chiropractic the doctor will take an extremely comprehensive history. Research has shown that 80% of a physicians diagnosis comes from the history provided by the patient. However; first, the doctor has to listen to the patients answers. After the history the doctor will then perform a physical examination. This exam will consist of orthopedic testing, strength and neurologic tests, postural evaluation, core stability evaluation, range of motion tests, palpation of the injury site and an active release evaluation in order to locate possible adhesion sites and nerve entrapments. If the doctor feels you are a candidate for the care we provide; treatment options will be discussed. With Dr. Tancredis extensive sports medicine experience, aggressive care can begin immediately if the patient chooses to do so. In other cases, when time is not vital to participation; a more conservative approach can be taken. In either case; the patients opinion regarding treatment ...
Particle-stabilised emulsions, also known as Pickering emulsions, have recently met rising interest for biocompatible and food applications. This symposium highlights their potential assets in terms of chemical stability.
In this work the development of a series of gold catalysts, essentially based on γ-alumina promoted with a small superficial fraction of Ce-Fe mixed oxides, is reported. The catalytic behaviour is evaluated in the water gas shift reaction. The formation of a Ce-Fe solid solution is evidenced by XRD and related to the catalytic activity where the importance of the Ce-Fe interaction is demonstrated. The best catalyst reached CO conversions very close to the equilibrium limit. A long-term stability test is performed and the loss of activity is observed and attributed to reaction intermediates. Almost complete recovery of the initial conversion is achieved after oxidation treatment, suggesting that the problem of stability could be overcome by a suitable change in the reaction parameters thus leading to a highly efficient catalyst for future applications in H2 production and clean-up. ...
Zn-doped calcium copper titanate (CCTO) was successfully synthesized by rapid laser sintering of sol-gel derived precursors without the conventional long-time heat treatment. The structural, morphological, and crystalline properties were characterized, and the performances of dielectrics and impedance were measured and discussed. The X-ray diffractometer results show that Zn-doped CCTO is polycrystalline in a cubic structure, according to the doping ratio of Ca(Cu2Zn)Ti4O12. Electron microscopy showed that Zn-doped CCTO has a denser microstructure with better uniformness with shrunken interplanar spacing of 2.598 nm for the plane (220). Comparing with undoped CCTO, the permittivity almost remains unchanged in the range of 102–106 Hz, demonstrating good stability on frequency. The electrical mechanism was investigated and is discussed through the impedance spectroscopy analysis. The resistance of grain and grain boundary decreases with rising temperature. Activation energies for the grain

We present new element organic frameworks based on Sn, Sb and Bi atoms connected via organic linkers by element-carbon bonds. The open frameworks are characterized by specific surface areas (BET) of up to 445 m2 g-1 and a good stability under ambient conditions resulting from a highly hydrophobic inner surface. They show good performance as heterogeneous catalysts in the cyanosylilation of benzaldehyde as a test reaction. Due to their catalytic activity, this class of materials might be able to replace common homogeneous element-organic and often highly toxic catalysts especially in the food industry.

A common approach for drug development includes the use of ICH stability conditions to subject the product to varying environmental conditions. Subsequent stability pulls are tested against a battery of tests to ensure the safety, purity, and potency of the drug product. Take the case of an injectable biologic product. Depending on the firms risk appetite and the regulatory pathway, the initial GMP batches are; filled in a vial or pre-filled syringe, packaged, and carefully carted to the stability chambers for their iterative cadence of stability followed by analytical testing. Acceptable stability profiles against the various product tests keep the program alive. Fast forward to design verification, where the device portion of the combination product is put through the ringer. Typically, this includes a bombardment of physical stressors on the final-finished package configuration, which simulates a variety of transit conditions one would expect for the mode of distribution chosen for the given ...

Cryopreservation is the preferred method for the long-term storage of many micro-organisms ... [more ▼]. Long-term genetic and functional stability is a fundamental requirement for the maintenance of microorganisms. Cryopreservation is the preferred method for the long-term storage of many micro-organisms, including cyanobacteria. The BCCM/ULC collection currently holds over 200 cyanobacterial strains as living cultures, but only 62 are maintained in a cryo-preserved state. The main limiting factors are the low levels of survival of some strains, as well as the long periods required to recover from cryopreservation, and thus the inability to rapidly deliver strains to clients.. The BRAIN-be project PRESPHOTO (preservation of photosynthetic micro-algae in the BCCM collections) (www.presphoto.ulg.ac.be) aims to improve the preservation of cyanobacterial and ...

This study aimed to evaluate the chemical stability of sincalide at 2 common storage conditions-room temperature and refrigeration-in an attempt to simulate the conditions faced during centralized reconstitution and subsequent distribution to regional clinical facilities. Sincalide is a peptide hormone product administered parenterally as an aid for diagnostic imaging of hepatobiliary conditions. With an estimated postreconstitution shelf-life of 8 h (updated by the manufacturer in 2014 with limited supporting data) and frequent shortages due to an intermittent supply, there is both clinical and economic value in the experimental determination of the true chemical stability of this agent. Methods: Sincalide was reconstituted and stored at both temperatures (n = 4 each), and samples were collected at predetermined time points. A validated high-performance liquid chromatography analytic method was used for quantification of the active ingredient in these samples. Results: Little to no chemical ...
Context • Intravenous ascorbic acid (IVAA) has been used extensively as part of the management plan for cancer patients in various medical clinics throughout the United States. The current research team has evaluated its effectiveness in patients with cancer as part of an ongoing research program. However, no data are available that support the chemical stability of intravenously injectable ascorbic acid (AA) to ensure its safety and efficacy in that patient population. Its clinical use as well as its use in research conducted in US Food and Drug Administration-approved clinical trials require validation of its stability.. Objective • The study intended to evaluate the chemical stability of the compounded IVAA that it prepares.. Design • The research team conducted a stability analysis within a 6-h period, a period longer than the time required for most infusions, which typically take approximately 2 h. The study evaluated the stability of AA intravenous sets, which are compounded ...
