The progression of odontogenic infections to necrotizing soft tissue infections (NSTIs) is unknown. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is used to predict risk of NSTI. This study aimed to (1) estimate the frequency at which odontogenic infections progress to NSTIs, (2) measure the value of LRINEC in predicting progression to NSTI, and (3) estimate the charges associated with managing NSTIs. This retrospective cohort study enrolled all subjects admitted for the management of odontogenic infections from 2001 to 2013. The primary predictor was the LRINEC score. The primary outcome was NSTI. The secondary outcome was billing charges. Descriptive and bivariate statistical analyses were performed, with significance set at a P-value of <0.05. Of 479 odontogenic infections, (1.0%) progressed to NSTI. The mean LRINEC for NSTI was 5.8 and for odontogenic infection was 3.4 (P=0.043). LRINEC parameters for the prediction of NSTIs had 60% sensitivity, 68.4% specificity, 20% positive predictive value, and 92.9% negative predictive value. The mean charge for NSTI was $319,337 and for odontogenic infections was $19,291 (P=0.051). One percent of odontogenic infections progressed to NSTIs. The LRINEC score was not able to identify all NSTIs. NSTIs are 16 times more costly.

Comparative higher-order structure analysis of antibody biosimilars using combined bottom-up and top-down hydrogen-deuterium exchange mass spectrometry
Source:Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, Volume 1864, Issue 12
Author(s): Jingxi Pan, Suping Zhang, Christoph H. Borchers
Hydrogen/deuterium exchange (HDX) coupled with mass spectrometry (MS) is a powerful technique for higher-order structural characterization of antibodies. Although the peptide-based bottom-up HDX approach and the protein-based top-down HDX approach have complementary advantages, the work done so far on biosimilars has involved only one or the other approach. Herein we have characterized the structures of two bevacizumab (BEV) biosimilars and compared them to the reference BEV using both methods. A sequence coverage of 87% was obtained for the heavy chain and 74% for the light chain in the bottom-up approach. The deuterium incorporation behavior of the peptic peptides from the three BEVs were compared side by side and showed no differences at various HDX time points. Top-down experiments were carried out using subzero temperature LC-MS, and the deuterium incorporation of the intact light chain and heavy chain were obtained. Top-down ETD was also performed to obtain amino acid-level HDX information that covered 100% of the light chain, but only 50% coverage is possible for the heavy chain. Consistent with the intact subunit level data, no differences were observed in the amino acid level HDX data. All these results indicate that there are no differences between the three BEV samples with respect to their high-order structures. The peptide level information from the bottom-up approach, and the residue level and intact subunit level information from the top-down approach were complementary and covered the entire antibody.

Polyols (Glycerol and Ethylene glycol) mediated amorphous aggregate inhibition and secondary structure restoration of metalloproteinase-conalbumin (ovotransferrin)
Source:International Journal of Biological Macromolecules, Volume 94, Part A

Under physical or chemical stress, proteins tend to form aggregates either highly ordered (amyloid) or unordered (amorphous) causing many pathological disorders in human and loss of proteins functionality in both laboratory conditions and industries during production and storage at commercial level. We investigated the effect of increasing temperature on Conalbumin (CA) and induced aggregation at 65°C. The enhanced Thioflavin T (ThT) and ANS (1-anilinonaphtalene 8-sulfonic acid) fluorescence intensity, show no shift on Congo red binding, additionally, transmission and scanning electron microscopy (TEM) (SEM) reveal amorphous morphology of the aggregate. Our investigation clearly demonstrated that polyols namely Glycerol (GL) and Ethylene glycol (EG) are so staunch to inhibit amorphous aggregates via restoring secondary conformation. Addition of polyols (15% GL and 35% EG) significantly decrease the turbidity, Rayleigh scattering ThT and ANS fluorescence intensity. The dynamic light scattering (DLS) data show that hydrodynamic radii (Rh) of the aggregates is ∼20 times higher than native CA while nearly similar for GL and EG protected CA due to condensation of core size with little difference.

A lectin from Canavalia virosa, Diocleinae subtribe, was purified by affinity chromatography with Sephadex G-50 matrix and named ConV. The primary structure of ConV was obtained by mass spectrometry and crystals were obtained by the vapor diffusion method at 293K and belonged to orthorhombic space group P21221 with two molecules in its asymmetric unit. The structure obtained presented Rfactor and Rfree of 18.91% and 24.92% respectively, with no residues in nonallowed regions of Ramachandran plot. The crystal structure was solved at 2.53Å and was demonstrated to be very similar to other lectins from the same subtribe. In inflammatory tests, ConV elicited paw edema, but incubation of lectin with glucose beforehand was able to reduce the edematogenic effect, indicating the involvement of the carbohydrate recognition domain in this process. The lectin also showed toxicity to rat C6 glioma cells, disrupting the mitochondrial membrane potential (ΔYm) and decreasing cell viability, indicating an anticancer potential for ConV. In silico studies confirmed that ConV interacts strongly with carbohydrates that comprise the N-glycans of glycoproteins. This finding corroborates the hypothesis which holds that the lectin domain interacts with glycans in molecular targets and that this contributes to the effects observed in biological activities.

Immunomodulatory effect of APS and PSP is mediated by Ca2+-cAMP and TLR4/NF-κB signaling pathway in macrophage
Source:International Journal of Biological Macromolecules, Volume 94, Part A
Author(s): Zhixue Wang, Zijing Liu, Lijng Zhou, Tingting Long, Xing Zhou, Yixi Bao
ObjectiveThis study is to investigate the role of second messengers and TLR4/NF-κB signaling pathway in the immunomodulatory activities of Astragalus polysaccharide (APS) and Polysaccharopeptide (PSP) in macrophages.MethodsRAW 264.7 macrophage cells were treated with APS, PSP, lipopolysaccharide (LPS), or NiCl2. Power-spectral method was used to detect protein kinase C (PKC) and Griess reaction to detect nitric oxide (NO). ELISA was conducted to detect cyclic adenosine monophosphate (cAMP), diglycerides (DAG), inositol 1, 4, 5-triphosphate (IP3), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Confocal laser scanning microscopy was performed to detect calcium level. qRT-PCR and Western blot was used to detect mRNA and protein expression of NF-κB.ResultsAPS and PSP significantly increased the concentrations of intracellular second messengers (NO, cAMP, DAG, IP3, Ca2+) and the activity of PKC in macrophages (p<0.05).The intracellular NF-κB mRNA and protein levels were significantly increased in macrophages treated by APS and PSP (p<0.05), whereas those were significantly decreased after NiCl2 incubation (p<0.05). Similarly, the secretion of TNF-α and IL-6 were significantly decreased by the treatment of NiCl2.ConclusionOur findings strongly suggest that Ca2+-cAMP and TLR4/NF-κB signaling pathways are, at least partly, involved in APS and PSP mediated immunomodulatory activities in macrophages.

A new validation technique for estimations of body segment inertia tensors: principal axes of inertia do matter
Source:Journal of Biomechanics
Author(s): Marcel M. Rossi, Jacqueline Alderson, Amar El-Sallam, James Dowling, Jeffrey Reinbolt, Cyril J. Donnelly
The aims of this study were to: (i) establish a new criterion method to validate inertia tensor estimates by setting the experimental angular velocity data of an airborne objects as ground truth against simulations run with the estimated tensors, and (ii) test the sensitivity of the simulations to changes in the inertia tensor components. A rigid steel cylinder was covered with reflective kinematic markers and projected through a calibrated motion capture volume. Simulations of the airborne motion were run with two models, using inertia tensor estimated with geometric formula or the compound pendulum technique. The deviation angles between experimental (ground truth) and simulated angular velocity vectors and the root mean squared deviation angle were computed for every simulation. Monte Carlo analyses were performed to assess the sensitivity of simulations to changes in magnitude of principal moments of inertia within ±10% and to changes in orientation of principal axes of inertia within ±10° (of the geometric-based inertia tensor). Root mean squared deviation angles ranged between 2.9° and 4.3° for the inertia tensor estimated geometrically, and between 11.7° and 15.2° for the compound pendulum values. Errors up to 10% in magnitude of principal moments of inertia yielded root mean squared deviation angles ranging between 3.2° and 6.6°, and between 5.5° and 7.9° when lumped with errors of 10° in principal axes of inertia orientation. The proposed technique can effectively validate inertia tensors from novel estimation methods of body segment inertial parameter. Principal axes of inertia orientation should not be neglected when modelling human/animal mechanics.

Uncertainty quantification of wall shear stress in intracranial aneurysms using a data-driven statistical model of systemic blood flow variability
Source:Journal of Biomechanics
Author(s): Ali Sarrami-Foroushani, Toni Lassila, Ali Gooya, Arjan J. Geers, Alejandro F. Frangi
Adverse wall shear stress (WSS) patterns are known to play a key role in the localisation, formation, and progression of intracranial aneurysms (IAs). Complex region-specific and time-varying aneurysmal WSS patterns depend both on vascular morphology as well as on variable systemic flow conditions. Computational fluid dynamics (CFD) has been proposed for characterising WSS patterns in IAs; however, CFD simulations often rely on deterministic boundary conditions that are not representative of the actual variations in blood flow. We develop a data-driven statistical model of internal carotid artery (ICA) flow, which is used to generate a virtual population of waveforms used as inlet boundary conditions in CFD simulations. This allows the statistics of the resulting aneurysmal WSS distributions to be computed. It is observed that ICA waveform variations have limited influence on the time-averaged WSS (TAWSS) on the IA surface. In contrast, in regions where the flow is locally highly multidirectional, WSS directionality and harmonic content are strongly affected by the ICA flow waveform. As a consequence, we argue that the effect of blood flow variability should be explicitly considered in CFD-based IA rupture assessment to prevent confounding the conclusions.

INTRODUCTION: The most effective treatment for osteoarthritis is TKR and THR but sizeable patient experience chronic pain causing discomfort. There has been shift in the usage of local anesthesia technique (LIA) over the general anesthesia in orthopedic surgeries mainly TKR. Pain control is important post surgery which includes opioid use, and other analgesics. LIA technique has taken increased focus due to early rehabilitation in patients with TKR and THR. METHOD: It was prospective, non-interventional and observational study. RESULTS: Outcomes were assessed with regards to the pain score and analgesic use post LIA. Patients with this technique experienced early mobilization and better pain control after surgery. There was decreased in the opioid usage and increased patient satisfaction. Break-through pain was also found to have decreased with LIA comparatively with only analgesic usage. CONCLUSION: The use of preoperative patient education as an important component in their fast-track recovery program. LIA protocol can achieve meaningful results and can be easily implemented both in tertiary care centers & community hospitals.

Chick Embryo Chorio Allantoic Membrane [CAM] is an extra embryonic membrane used mainly for gas exchange and transport of calcium from the egg shells to the embryo during its development. It is used to study new blood vessel formation and its inhibition in response to tissues, cells or soluble factors such as antibodies. CAM is broadly used in oncology, biology, pharmacy and tissue regeneration research. There are 46 morphologically distinct stages of chick development beginning with a freshly laid egg and ending with a fully developed and hatched chick. These stages help provide consistency and coordination between the various areas that use the chick embryo model. It is a novel technique to facilitate the discovery and development of newer drugs, circumventing the use of animals. Due to its ease of availability, extensive vascularisation, and immuno deficient environment, it is used to study morpho functional aspects of angiogenesis process in vivo. Progress in imaging and chick culture technologies is advancing real-time visualization of dynamic biological events. Cell line studies have attained utmost importance due to advanced technologies and are used as an alternative to animal experiments. Jurkat cells derived from T Lymphocyte have been developed to provide a link between the Immunomodulatory and anti angiogenic aspect of the drug. The present study was carried out to evaluate the anti-angiogenetic activity of crude extract of Anogeissus latifolia using chick embryo chorioallantoic membrane and cell line models. Direct drug injection and disc impregnation methods were followed for chick embryo. Sulphorhodamine B assay was followed for cell line study. Reduction in the blood vessel branching was observed in chorio allantoic membrane and reduction in cell number was observed for cell line studies indicating that the drug possess anti angiogenic activity.

Highly sensitive, simple and economic spectrophotometric and fluorimetric methods were developed for the determination of posaconazole (POS) in pharmaceutical preparations and spiked human plasma through solvent solvent extraction technique. The proposed methods are based on measuring the absorbance of the drug in methanol at 262 nm and the native fluorescence intensity in isopropanol at 378 nm after excitation at 262 nm. The absorbance concentration plot and fluorescence intensity-concentration plot were rectilinear over the range 0.612-17.500 μg/ml and 22-550 ng/ml with a lower detection limit of 0.202 μg/ml for the spectrophotometric and 7 ng/ml for the fluorimetric analysis and the mean percent recovery were found to be 100.192 and 100.002 for spectrophotometric and fluorimetric techniques respectively. Both methods were validated according to ICH guidelines and showed good accuracy and precision with no significant difference compared with the reported HPLC method. It can be concluded that these methods can be used for determination of POS in dosage form and spiked human plasma.

Immune thrombocytopenia and its association with lymph node tuberculosis A dilemma!
2016-10-16T05-23-22Z
Source: The Southeast Asian Journal of Case Report and Review
Sangita Deepak Kamath, Neeraj Jain, Saurabh Pathak, Ballamudi Srinivas Rao.
Background: Although various hematologic abnormalities are known to occur with tuberculosis, association of immune mediated thrombocytopenia with tuberculosis is uncommon. Newly diagnosed immune thrombocytopenia in TB is rare; only 27 cases have been reported so far. Case: We report a case of axillary lymph node tuberculosis who presented with immune thrombocytopenia. An eighteen year old girl was admitted to our hospital with excessive vaginal bleed of one week duration followed by the development of petechial lesions and ecchymosis over legs, hands and mouth. She also had solitary, firm, left axillary lymphadenopathy. A diagnosis of immune mediated thrombocytopenia (ITP) was made from peripheral blood smear and bone marrow examination. Intravenous methylprednisolone (30mg/kg body weight) followed by oral prednisolone (1mg/kg) failed to elicit any sustained platelet response. Fine needle aspiration cytology of the left axillary lymphadenopathy done later revealed tuberculosis. After two weeks of starting anti-tuberculous therapy, the platelet count returned to normal and she was off all therapy for ITP thereby suggesting likely association between tuberculosis and immune thrombocytopenia. Conclusion: This case report illustrates the causal association between immune thrombocytopenia and tuberculosis.

The fast rate of urbanization, has considerably elevated the prevalence of upper respiratory tract diseases, especially that of allergic rhinitis (AR).More than 10-30 % of the population, world-wide, is found to be affected by AR. Conventional therapy of AR is dominated by oral dosage forms of H1 blocker anti-histaminic agents and nasal decongestants while the use of steroids is reserved only for severe and non-responsive cases. Frequent administration of these agents, the severity of their side effects, significantly contributes to poor compliance by the patients. In view of this, an in-situ gelling nasal system for combined and sustained delivery of Deslorantadine (DSL), a third generation antihistaminic and Phenylephrine hydrochloride, α1-adrenergic blocker has been designed. The mechanism employed for sustained release of APIS is based on in- situ transition of trigger sensitive polymeric solutions, into more viscous and muco-adhesive gel in the nasal passage. The sol and gel phases of the formulations were characterized for pH, viscosity, muco-adhesive strength, contents and diffusion profiles of APIs. The formulation CP4H1K1DP, based on pH sensitive carbomer, possessed superior gelling characteristics, physiologically acceptable pH range, muco-adhesive strength (5865 dynes/cm2) and prolonged diffusion (in-vitro) over 6 hrs. The key stability parameters of this formulation were unaffected during the storage over 30 days, suggesting its suitability as an alternative to the existing treatment options for AR.

Background: A surgical site infection or SSI, is an infection of a wound developed from surgery which may affect either closed wounds or wounds that were left open to heal whereas, diabetic foot ulcers are caused by neuropathic (nerve) and vascular (blood vessel) complications of the disease. Treatment of wound site infections needs a multidimensional approach, includes the right choice of antibiotic, the cleanliness of wound site, choice of topical agent, rate of bacterial killing, plasma drug concentration(PDC) at site of infection and in diabetic cases glycemic control. Antibiotic therapy plays the most important role in management of wound site infections; the choice is made by performing culture sensitivity. The killing effect of an antimicrobial agent can be expressed as the rate of killing a fixed concentration of drug under controlled conditions. The resulting graphic depiction is known as "Time kill curve". Objectives: To determine 3log phase decrease between growth control and antibiotic serial dilutions and selecting drug of choice and also to compare 100 fold decrease between growth control and antibiotic plus add on therapy and further establishing time kill curve, by plotting CFU on Y-axis and time on X-axis. Method: Its an Observational and Comparative study carried out for 6 months, designed to study different antibiotics effect on 35 patients at different concentrations. Results: Viable colonies from those dilutions containing 5-50CFU were counted. The colony counts were multiplied with dilution factor to obtain CFU per milliliter. The results were tabulated as CFU per milliliter (y-axis) vs time (x-axis) on semi-log paper (CFU per milliliter can be converted to log10values).The antimicrobial agent concentration that showed 3log10CFU/ml fold decrease when compared with the growth control was determined. The time when the 3log10CFU/ml fold decrease occurred when compared with the growth control was determined. Conclusions: According to Time-Kill Curve we can conclude that Amoxicillin+Clavulanic acid is effective on Escherichia coli, Amikacin is effective on Pseudomonas aeruginosa, Ampicillin + Ciprofloxacin is effective on Staphylococcus aureus, Ampicillin + Sulbactam is effective on Klebsiella pneumonia. Time-Kill Curve method may be employed to establish the log phase difference in killing effect by the desired groups of antibiotics and therefore the Antibiotic that shows the highest log phase difference can be the selected as drug of choice to treat the condition.

A purpose was to develop and validate a simple, sensitive, high throughput LC-MS/MS method for quantification of mirabegron in human plasma. Mirabegron is a selective agonist for human beta 3-adrenoceptor. The method involves solid-phase 96 well plate extraction using mirabegron-d5 as an internal standard (ISTD). Chromatographic separation was achieved on Unisol C18 3μ 100Ǻ 4.6 X 100mm column with a mobile phase consist of 0.1% ammonia solution (v/v) and methanol (40:60 v/v) at a flow rate of 1.0mL/min and the total run time was 4.0 min. Detection was carried out through positive electro-spray ionization mode by multiplexing of two product ions. Finally the method was developed with the lower limit of quantification as low as 0.1 ng/ml. The method was validated for linearity, precision, accuracy and stability. All the results were within the pre defined acceptance criteria. The method is ready to use in a pharmacokinetic studies.
