Calcaneal fractures: Where are we now?

This review article on the current management for calcaneal fractures discusses the advantages and disadvantages of different treatment options including the problems encountered. Controversies are described and the evidence reviewed. The management of some types of displaced intra-articular calcaneal fractures remains contentious; is there a preferred stabilisation method for each type of calcaneal fracture? How constant is the "constant fragment" in an intra-articular calcaneal fracture and what is the evidence for primary arthrodesis and what is its place in these fractures

Effect of the Nuclear Factors EmBP1 and Viviparous1 on the Transcription of the Em Gene in HeLa Nuclear Extracts

Templates constructed from the wheat Em and maize rab28 promoters are efficiently and accurately transcribed in the well-characterized cell-free transcription system prepared from HeLa nuclei. Deletion analysis of the Em promoter indicates that a G-box (CACGTG) element (Em1b) is required for transcription. USF, a Myc transcription factor in HeLa nuclear extracts, activates transcription by binding to Em1b, as shown by the ability of an antibody raised against USF to inhibit transcription and to interfere with Em1b complex formation in an electrophoretic mobility shift assay. The addition of the recombinant Viviparous1 protein from maize to HeLa nuclear extracts specifically stimulated transcription of the Em promoter but was dependent on the presence of USF in the extract. In USF-depleted extracts, the addition of recombinant EmBP1, a basic leucine zipper transcription factor from wheat, activated transcription through Em1b as well as from a similar G-box in the adenovirus major late promoter. Our study demonstrates that the basic transcriptional apparatus in HeLa nuclear extract supports transcription from plant promoters and can be used to assay the function of certain plant nuclear proteins, thereby helping to determine their effects on transcription

MR texture analysis in differentiating renal cell carcinoma from Lipid-poor angiomyolipoma and oncocytoma

OBJECTIVES: To assess the utility of Magnetic resonance texture analysis (MRTA) in differentiating renal cell carcinoma (RCC) from lipid-poor angiomyolipoma (lpAML) and oncocytoma. METHODS: After ethical approval, 42 patients with 54 masses (34 RCC, 14 lpAML and six oncocytomas) who underwent MRI on a 1.5 T scanner (Avanto, Siemens, Erlangen, Germany) between January 2011 and December 2012 were retrospectively included in the study. MRTA was performed on the TexRAD research software (Feedback Plc., Cambridge, UK) using free-hand polygonal region of interest (ROI) drawn on the maximum cross-sectional area of the tumor to generate six first-order statistical parameters. The Mann-Whitney U test was used to look for any statically significant difference. The receiver operating characteristic (ROC) curve analysis was done to select the parameter with the highest class separation capacity [area under the curve (AUC)] for each MRI sequence. RESULTS: Several texture parameters on MRI showed high class separation capacity (AUC > 0.8) in differentiating RCC from lpAML and oncocytoma. The best performing parameter in differentiating RCC from lpAML was mean of positive pixels (MPP) at SSF 2 (AUC: 0.891) on DWI b500. In differentiating RCC from oncocytoma, the best parameter was mean at SSF 0 (AUC: 0.935) on DWI b1000. CONCLUSIONS: MRTA could potentially serve as a useful non-invasive tool for differentiating RCC from lpAML and oncocytoma. ADVANCES IN KNOWLEDGE: There is limited literature addressing the role of MRTA in differentiating RCC from lpAML and oncocytoma. Our study demonstrated several texture parameters which were useful in this regard

Gliotoxin Fermentation Agar (GFA) Medium and Nutrient Glucose Agar   (NGA) medium with different carbon and nitrogen sources were used to study the impact of carbon and nitrogen sources on Trichoderma harzianum Rifai and Bacillus subtillus Cohn antagonistic efficiency against growth of Botrytis allii Munn. Results indicated that Trichoderma harzianum gave the highest inhibition % in growth of Botrytis allii when Sucrose was used as a carbon source while the lowest values of inhibition% were appeared by application of Mannitol as a carbon source. Trichoderma harzianum gave the highest inhibition% in growth of B.allii when use Potassium nitrate  as a nitrogen source while the lowest values of inhibition% in growth of B.allii were obtained by application of Beef extract as a nitrogen source. Results showed also that Bacillus subtillus gave the highest inhibition% in growth of B.allii when Mannitol was used as a carbon source while the lowest values of inhibition% in growth of B.allii were appeared by application of Sucrose as a carbon source. Bacillus subtillus gave the highest inhibition% in growth of B.allii when use Glutamic acid as a nitrogen source while the lowest values of inhibition% in growth of B.allii were appeared by application of Tryptophan as a nitrogen source.

Evaluation of IR Spectral Analysis and Dyeing Parameters for Plasma and /or Nano-Silver Treatments of Polyester and Nylon Fabrics

In our work of this paper, we study the effect of surface modification of polyester and nylon fabrics induced by DC plasma discharge and/ or nano-siliver treatments .DC plasma discharge was employed at first, as a function of plasma device parameters including different time, different current and different hydrostatic pressure using chemically inert working gas: argon or nitrogen. Optimization of the performance of the applied DC plasma discharge with various applied conditions were performed using Fourier Transform Infra-Red (FTIR) Spectroscopy spectral analysis, by following up the changes in the peak intensity values of the characteristic functional groups that characterize polyester fabric. Then the dyeing properties of different pretreated fabrics with plasma by the best conditions are subjected to nano-silver treatment by concentration 50 ppm under the effect of different dye concentrations, different dyeing temperature and different dyeing time. Finally, the fastness properties to light and washing for the treated samples were studied. The results obtained showed that both of the dyeing parameters and fastness properties were highly improved by the treatment of fabrics by either individual plasma treatment or combined DC cold plasma and nano-silver treatments

MICROPROPAGATION AND EVALUATION OF GENETIC STABILITY OF FOXGLOVE TREE (Paulownia tomentosa)

This reasearch work aimed to fine-tune micropropagation of Paulownia tomentosa in addition to assessing the genetic stability of in vitro raised clones from it. Paulownia tomentosa explants were surface sterilized using clorox (commercial bleach 5.25% sodium hypochlorite) at 10, 20, 25 and 30% + 0.5 g/l mercuric chloride (HgCl2) at different duration times, i.e. 10, 15, 20 and 25 min. In the multiplication stage, shoots were transferred to MS medium at ¾ strength containing BAP and Kin each at (0, 0.5, 1, 2, and 4 mg/l). Whereas, the rooting medium was MS medium at ¾ strength with IBA and NAA treatments each at 0, 0.5, 1, 2, and 4 mg/l. Sterilized explant with 30% Clorox for 20 min recorded highest survival percentage. The treatment of Kin at 4 mg/l gave higher significant shoot length. Whereas BAP application at 2 and 4 mg/l gave highest significant value of both shoot number and leaf number. Both IBA and NAA at 0.5 or 1 mg/l gave highest significant root number/shoot. Whereas, auxin at 4 mg/l gave highest significant root lengths. Young plantlets resulted from in vitro were acclimitized successfully in a mixture of peat moss: perlit (2: 1) by volume that showed 85.93% survival.  The genetic stability of in vitro raised Paulownia tomentosa clones was assessed by using intersimple sequence repeats (ISSRs) markers. All of the three ISSR primers screened, produced clear, reproducible and scorable bands.      The molecular size of Polymerase Chain reaction (PCR) products generated 22 fragments by these ISSR ranged from ≈460 to18660 bp. All banding profiles from micropropagated plants were monomorphic and similar to those of the mother plant, indicating 100% similarity. This confirmed the true to type nature of the in vitro raised clones

However, in recent years, wound-rotor motors have received special attention because of their broad use as generators in wind turbine units, as well as in some large power applications in industrial plants. Some classical approaches perform the detection of certain faults based on the fast Fourier transform analysis of the steady state current (motor current signature analysis); they have been lately complemented with new transient time-frequency-based techniques to avoid false alarms. Nonetheless, there is still a need to improve the already existing methods to overcome some of their remaining drawbacks and increase the reliability of the diagnostic. In this regard, emergent technologies are being explored, such as the analysis of stray flux at the vicinity of the motor, which has been proven to be a promising option to diagnose the motor condition. Recently, this technique has been applied to detect broken rotor bar failures and misalignments in cage motors, offering the advantage of being a noninvasive tool with simple implementation and even avoiding some drawbacks of well-established tools. However, the application of these techniques to wound rotor IMs (WRIMs) has not been studied. This article explores the analysis of the external magnetic field under the starting to detect rotor winding asymmetry defects in WRIMs by using advanced signal processing techniques. Moreover, a new fault indicator based on this quantity is introduced, comparing different levels of fault and demonstrating the potential of this technique to quantify and monitor rotor winding asymmetries in WRIMs.This work was supported by the Spanish "Ministerio de Ciencia Innovacion y Universidades" and Fondo Europeo de Desarrollo Regional program in the framework of the "Proyectos de I+D de Generacion de Conocimiento del Programa Estatal de Generacion de Conocimiento y Fortalecimiento Cientifico y Tecnologico del Sistema de I+D+i, Subprograma Estatal de Generacion de Conocimiento" under Grant PGC2018-095747-B-I00.Zamudio-Ramírez, I.; Antonino Daviu, JA.; Osornio-Rios, RA.; Romero-Troncoso, RDJ.; Razik, H.

Synthesis, Characterization, ADME Study and Anti-proliferative evaluation against MCF-7 breast cancer cell line of new analog of a 4-aminophenyl quinazolinone derivative

New series of 4-aminophenyl quinazolinone attached to an aromatic aldehyde moiety has been designed. Compound (ZA) was synthesized by a reaction of benzene-1,4-diamine with 2-aminobenzoic acid. The reaction between (ZA) intermediate and different substituted aromatic aldehydes (R1- R6) is considered one of the most common chemical reactions for the synthesis of imine compounds (Schiff bases) to produce compound (ZA1-ZA6). FTIR, 1H-NMR, and 13C-NMR have been used to confirm the chemical structures of various substances. MTT assay was used to assess in vitro anti-proliferative action for estrogen receptor alpha. The anti-proliferative study discovered a dose-dependent effect on cell proliferation in breast cancer (MCF-7) with inhibitory concentration In comparison to the reference medication tamoxifen (IC50 of 133.4µg\mL), IC50 of the compounds (ZA1, ZA2, ZA3) was 0.07964, 57.43 & 0.002717 µg\mL, respectively at 72 hours on same cell line mentioned above, that also signifies that compound ZA1 has a significantly greater effect on this cell line typ

Evaluation of the Detectability of Electromechanical Faults in Induction Motors Via Transient Analysis of the Stray Flux

© 1972-2012 IEEE. The stray flux that is present in the vicinity of an induction motor is a very interesting information source to detect several types of failures in these machines. The analysis of this quantity can be employed, in some cases, as a supportive tool to complement the diagnosis provided by other quantities. In other cases, when no other motor quantities are available, stray flux analysis can become one of the few alternatives to evaluate the motor condition. Its noninvasive nature, low cost, and easy implementation makes it a very interesting option that requires further investigation. The aim of this work is to evaluate the suitability of the stray flux analysis under the starting transient as a way to detect certain faults in induction motors (broken rotor bars and misalignments), even when these types of faults coexist in the motor. To this end, advanced signal processing tools will be applied. Several positions of the flux sensors are considered in this study. Also, for the first time, a fault indicator based on the stray flux analysis under the starting is introduced and its sensitivity is compared versus other indicators relying on other quantities. It must be emphasized that, since the capture of the transient and steady-state flux signals can be carried out in the same measurement, the application of the approach presented in this work is straightforward and its derived information may become crucial for the diagnosis of some faults.Ministerio de Economía y Competitividad’ (MINECO) and FEDER program in the framework of the ‘Proyectos I+D del Subprograma de Generación de Conocimiento, Programa Estatal de Fomento de la Investigación Científica y Técnica de Excelencia’ (ref: DPI2014-52842-P)

PRODUCTION OF L-TRYPTOPHAN BY MUTANTS OF CORYNEBACTERIUM GLUTAMICUM

L-Tryptophan, is one of the amino acids, also is one of the 9 essential amino acids of human which cannot be synthesized internally by him, microbial production is the main method for obtaining tryptophan for commercial uses. Typical microorganisms used for tryptophan production are E. coli and C. glutamicum. In this study, random mutations is performed on two strains of C. glutamicum to increase tryptophan production, the produced tryptophan measured by bioassay using tryptophan auxotroph E. coli (JW1254-2) strain, the mutations are performed using UV radiation. To detect and compare the difference between the parent strains and the muted strains genetically two molecular markers were used start codon targeted polymorphism (SCoT) and Inter-simple sequence repeats (ISSR). Tryptophan remarkably increased after C. glutamicum mutation to reach 278.4 µg/ml (1257.4% increment) from one mutated strain. Molecular genetics methods showed an ability to distinguish between the two original strains and their mutants and it showed the importance of the mutation by UV radiation for increasing the productivity of the bacteria to tryptophan
