Using foreign inclusion detection to improve parsing performance
Inclusions from other languages can be a significant source of errors for monolin-gual parsers. We show this for English in-clusions, which are sufficiently frequent to present a problem when parsing German. We describe an annotation-free approach for accurately detecting such inclusions, and de-velop two methods for interfacing this ap-proach with a state-of-the-art parser for Ger-man. An evaluation on the TIGER cor-pus shows that our inclusion entity model achieves a performance gain of 4.3 points in F-score over a baseline of no inclusion de-tection, and even outperforms a parser with access to gold standard part-of-speech tags.
Preparation and evaluation of herbal cream
A herbal fairness cream was formulated using herbal extracts which have potential antioxidant activity. Creams were basically formulated using the hydro alcoholic extracts of Glycyrrhiza glabra (root and Stolons),Camellia sinensis (leaf), Pleurotus osttreatus (mushroom plant). The prepared formulation were subjected to different evaluation like spreadability, pH, appearance, viscosity, drug content, irritability and antioxidant properties. The prepared formulation was found stable and effective. Among the several combination Liquorice & Green Tea based preparation shows better results. From the results it was concluded that it is possible to develop creams containing herbal extracts having potent antioxidant and fairness property and can be used as the provision of a barrier to protect skin.  
Modulation of arsenic-induced oxidative stress and protein metabolism by diphenyleneiodonium, 24-epibrassinolide and proline in Glycine max L.
Arsenic (As)-toxicity is a major constraint for crop production. The present study was intended to examine the comparative ameliorative effects of diphenyleneiodonium (DPI), 24-epibrassinolide (EBL) and proline (Pro) on As-stress in Glycine max L. Seeds of Glycine max L. were subjected to As (100 μM) singly, and together with DPI (10 μM), EBL (0.5 μM) or Pro (10 mM), for five days, and were then analyzed. Experimental results showed that As treatment caused a substantial fall in growth traits like germination percentage, radicle length and dry mass, which was accompanied by As accumulation. Additionally, As application also revealed reduced viability, total protein content and activities of antioxidative enzymes (superoxide dismutase, catalase and ascorbate peroxidase), while it increased the levels of total sugar, proline and oxidative stress markers such as electrolyte leakage, reactive oxygen species, lipid oxidized products, protein carbonyls and hydroperoxides, Amadori and Maillard reaction products, malondialdehyde-/4-hydroxy-2-nonenal-protein adducts, protease and proteasome. Isozymes of antioxidative enzymes were also observed to be altered considerably under As-stress. Impressively, DPI, EBL and Pro played their role as protective agents, hence caused enhanced growth and reduced As accumulation. These protective chemicals also improved the viability, accruals of total protein, total sugar and endogenous proline, and activities of antioxidants, while they reduced the levels of oxidative stress markers. Our findings demonstrated the involvement of DPI, EBL and Pro in As-stress tolerance in Glycine max L. Further, Pro appears to be superior to DPI and EBL, in alleviating As-induced responses in Glycine max L
Study and analysis of the coagulation factors and their natural inhibitors levels in apheresis derived platelet concentrate units over a five-day storage period
Background: The possibility of utilizing clotting factors in the plasma phase of apheresis platelet concentrates, as a supplement to the standard FFP transfusion for clotting factor replacement needs to be explored. In this study, it was proposed to assess the effect of storage on clotting factors and inhibitors in stored apheresis platelet concentrates. This would give an insight into the hemostatic potential of the plasma phase of the apheresis platelet concentrates.Methods: This study was conducted on a sample size of 45 apheresis platelet concentrate units harvested on Amicus cell separator. Basic coagulation workup along with various coagulation factors and their natural inhibitors were studied in the apheresis platelet concentrates on day ‘0’ and day ‘5’ of the collection.Results: Prothrombin time and activated partial thromboplastin time of the apheresis platelet concentrates was increased on day ‘5’ of the collection but were within the normal range. Fibrinogen, Factor XII, and VWF: Ag showed an increase on day ‘5’ of collection. Protein C, protein S activity, and antithrombin decreased on day ‘5’ of collection. Also, Factors II, VII, IX, X, XI decreased on day ‘5’. The highest fall in activity was seen in the case of Factors V and VIII. Despite the fall, all the clotting factors were maintained within their normal range.Conclusions: Although the activity of most of the coagulation factors showed a decrease, it was maintained within their normal range and efficacy. Therefore, a reasonable hemostatic potential of the clotting factors is expected to be maintained in apheresis platelet concentrates after a storage period of five days at room temperature

Solubility enhancement of biperidine HCl by complexation with hydroxypropyl β-cyclodextrin
Oral route is the simplest and easiest way of drug administration, because of the greater stability, lesser bulk, and cheap cost of production, accurate dosage and easy process, solid oral dosage forms have several advantages over other dosage forms. All the poor water soluble drugs after oral administrations are not well absorbed and thus leads to decrease in inherent efficiency of drugs. Therefore, for oral drug delivery system the improvement of drug solubility thereby its oral bio-availability is the most important aspect of drug development process. Biperiden HCl is a potent drug (Maximum daily dose is 16mg/day), having extensive first pass metabolism resulting in poor Bioavailability. The pharmacokinetic profile of this drug showed 33±5 % Bioavailability and 18-24 hours elimination half-life (t1/2). In the present study attempt has been made to prepare and characterize inclusion complex of Biperiden HCl with Hydroxypropyl β-Cyclodextrin. The inclusion complexes prepared by different methods i.e. Physical mixture, Kneading and Solvent evaporation methods. The prepared complexes were characterized using FT-IR. The inclusion complex prepared by Kneading method exhibited greatest enhancing in solubility and faster dissolution (93.98% drug release in 60 min) of Biperiden HCl
DEVELOPMENT OF CIPROFLOXACIN LOADED THROAT PAINT FOR THE TREATMENT OF STREP THROAT INFECTION
Objective: This study is to enhance the solubility and sustained release of ciprofloxacin (CPX) drug by amplifying the adhesive capability of formulation by forming throat paint for the Streptococcal pharyngitis, a sore throat infection.
Methods: Solid dispersion was prepared by solvent evaporation technique, in which three different ratios of Polyethylene glycol-6000 (PEG-6000) were selected, and the best ratio of solid dispersion was selected after characterization including Scanning electron microscopy (SEM) and Differential scanning calorimetry (DSC) with evaluation parameters including % yield, drug content, and drug solubility. In the case of throat paint, out of six different formulations, the best formulation was selected through viscosity, in vitro mucoadhesion, in situ release study, and spreadability parameters.
Results: The DSC and SEM data proved that solid dispersion has a different moiety than its ingredients but it is quite a stable form. Formulation MD-2 was selected as the best formulation which able to increase the solubility of the drug by more than 3.5 folds, at the same time it shows the highest rate of drug dissolution of 13.951 μg/ml with % yield (97.199±0.167%) and drug content (96.425%). Throat paint was formed by fusion and trituration process and out of all six formulations F3 was selected as the best formulation on the basis of Viscosity (11932 Centi poise), Spreadability (17.621), Mucoadhesion (3937.481 dyne/cm2), and drug release (90.336±0.6%).
Conclusion: Solid dispersion was successfully prepared with 3.5 times of solubility enhancement capability in comparison with pure CPX drug. The throat paint releases the drug (≥3 h) in a sustained manner with high mucoadhesive force
A comparison of platelet count in severe preeclampsia, mild preeclampsia and normal pregnancy
Background: Preeclampsia, the most common of hypertensive disorders of pregnancy is an idiopathic multisystem disorder affecting 2 – 10% of all pregnancies and together they form one member of the deadly triad, along with hemorrhage and infection that contribute greatly to the maternal morbidity and mortality rates. The identification of this clinical entity and effective management play a significant role in the outcome of pregnancy. Platelet count is emphasized to play a significant role in hemostasis mechanism of preeclampsia and the degree of thrombocytopenia increases with severity of preeclampsia. This study was conducted to find correlation of platelet count in severe preeclampsia, mild preeclampsia and normal subjects.Methods: Total 140 subjects, 70 control and 70 cases were enrolled in the study. Samples for platelet count were collected and estimation was carried out by the auto-analyzers. The statistical evaluation is done using SPSS version 22 along with Anova and student t-test.Results: The mean platelet count was significantly lower (p <0.05) in mild and severe preeclampsia than that in the normal pregnancy. Decreased platelet count in severe preeclampsia was significant compared to that in mild preeclampsia.Conclusions: The frequency of thrombocytopenia was found to be directly related with the severity of disease, so platelet count can be used as a simple and cost effective tool to monitor the progression of preeclampsia, thereby preventing complications to develop during the gestational period
