Authors: Praveenkumar S. , Srigitha S. Nath , Dinesh Ram G. , Ramesh R. 
Published: November 2018

Background:
In this paper, the design and computational modeling of microfluidic
channel capable of separating platelets and Red Blood Cell (RBC) from the other blood cells are
proposed.

Materials and Methods:
Separation based on their sizes is made possible by utilizing negative dielectrophoretic
(n-DEP) force in fusion with drag force. An array of 38º angled electrode separated
by 70 μm distance is designed within the microchannel and analyzed for non-uniform electric
field distribution.

Results and Conclusion:
The molecule movement within the microchannel under induced electric
field is simulated to demonstrate the separation using the particle trajectories module. A numerical
study is performed for the calculation of Clausius Mossotti (CM) factor, n-DEP force and drag
force.
Spontaneous Chest Abscess Caused by Salmonella Enterica subsp. Arizonae in the Desert Southwest; A Case Report and Review of the Current Literature
Authors: Antony Suresh , Cooper Leigh 
Published: November 2018

:
Salmonella enterica subspecies arizonae is a rare pathogen but has been reported in the
literature in immunosuppressed and rarely immunocompetent patients. Most disease states have
been reported in animals and reptiles. Human exposure has resulted in a range of complications
from skin and soft tissue infections to bacteremia and periprosthetic joint infections. Predisposing
factors such as age, comorbidities, and use of Mexican folk healing practices increase the risk of
developing an infection. S. arizonae has been associated with gastrointestinal infections in several
parts of the country and on rare occasions have been isolated from skin and soft tissues, prosthetic
joints, and empyema.

Case:
This is a unique case of a large de novo chest abscess that developed in a 59-year-old diabetic
male from the Southwest region with cultures growing Salmonella enterica subspecies arizonae.
This patient presented without predisposing factors and did not appear to be ill at the time of admission.
He was treated successfully by aspirating the abscess along with a 2-week course of ceftriaxone
intravenously.

Published: November 2018

Background:
Alzheimer's disease (AD) is a neurodegenerative disease characterized by the
progressive and incapacitating decay of cognitive, neuropsychiatric, and behavioral manifestations.
L-tryptophan is the precursor amino acid of serotonin, which is a neurotransmitter responsible for
mood balance and the sense of well-being and can be administered in the form of nanoparticles.

Objective:
This study analyzed the effectiveness of L-tryptophan nanoparticles and L-tryptophan on
behavioral physiological alterations resulting from AD in animal models.

Methods:
The sample consisted of 50 Rattus norvegicus rats, divided in 10 groups with 5 animals
each: one negative control (NC), three positive control groups (C3, C7, and C21), three groups treated
with L-tryptophan nanoparticles (T3N, T7N, and T21N) at the concentration of 1.5 mg, and three
groups treated with L-tryptophan (T3L, T7L, and T21L) at the concentration of 1.5 mg. The rats underwent
stereotactic surgery to induce AD through the injection of amyloid beta-amyloid peptide1-42 in
the intracerebroventricular region. All rats were submitted to pre- and post-surgery and post-treatment
motor behavior evaluation through the Later Water Maze (LWM) and elevated cross-labyrinth (ECL).
Histological analysis was performed to verify the presence of senile plaques, and the statistical analysis
used the unpaired T-test.

Results:
Significant intergroup differences were observed in some of the evaluated parameters between
treated and untreated groups.

Conclusion:
It was concluded that the treatment with L-tryptophan nanoparticles was beneficial to
improve behavioral reactions in the Alzheimer's model.
Smart Gn-Keto Nanohybrid Embedded Topical System for Effective Management of Dermatophytosis
Authors: Sharma Nisha , Misra Shashikiran 
Published: November 2018

Background and Objectives: Dermatophytosis (topical fungal infection) is the 4th common
disease in the last decade, affecting 20-25% world’s population. Patients of AIDS, cancer, old age senescence,
diabetes, cystic fibrosis become more vulnerable to dermatophytosis. The conventional topical
dosage proves effective as prophylactic in preliminary stage. In the advanced stage, the therapeutics
interacts with healthy tissues before reaching the pathogen site, showing undesirable effects, thus resulting
in pitiable patient compliance. The youngest carbon nano-trope “Graphene” is recently used to manipulate
bioactive agents for therapeutic purposes. Here, we explore graphene via smart engineering by
virtue of high surface area and high payload for therapeutics and developed graphene–ketoconazole
nanohybrid (Gn-keto) for potent efficacy towards dermatophytes in a controlled manner.
</P><P>
Methods: Polymethacrylate derivative Eudragit (ERL100 and ERS 100) microspheres embedded with
keto and Gn-keto nanohybrid were formulated and characterized through FTIR, TGA, and SEM. In vitro
drug release and antifungal activity of formulated Gn-keto microspheres were assessed for controlled
release and better efficacy against selected dermatophytes.
</P><P>
Results: Presence of numerous pores within the surface of ERL100 microspheres advocated enhanced
solubility and diffusion at the site of action. Controlled diffusion across the dialysis membrane was observed
with ERS100 microspheres owing to the nonporous surface and poor permeability. Antifungal
activity against T. rubrum and M. canis using microdilution method focused on a preeminent activity
(99.785 % growth inhibition) of developed nanohybrid loaded microspheres as compared to 80.876% of
keto loaded microspheres for T. rubrum. The culture of M. canis was found to be less susceptible to
formulated microspheres.

Conclusion:
Synergistic antifungal activity was achieved by nanohybrid Gn-Keto loaded microspheres
against selected topical fungal infections suggesting a vital role of graphene towards fungi.

Authors: Rajendiran Anjana , Vijayakumar Saravanan , Pan Archana 
Published: November 2018

Background:MicroRNAs (miRNAs) are a class of small non-coding, endogenous RNAs that regulate gene expression at post-transcriptional level. In plants, miRNAs are usually of 18-24 nucleotide in length and play humongous role by aiding in development, growth, defense, biotic and abiotic stress responses, etc.Objective:Arachis hypogaea is an economically important oil seed crop and human dietary source cultivated mostly in tropical and subtropical regions. In the present study, an initiative was taken to uncover miRNAs, their targets and functions in this important plant species. </P><P> Method: Comparative genomics strategy coupled with bioinformatics approaches was deployed for the identification of miRNAs, their corresponding targets and functions by exploiting biological databases and tools.Results:The study was able to identify 34 conserved miRNA candidates, belonging to 17 miRNA families, contributed by 23 and 3 precursor miRNAs from A. hypogaea Expressed Sequence Tags (EST) and Genome Survey Sequences (GSS), respectively. As well, 495 EST and 917 unigene sequences were predicted as targets for the identified miRNAs. Herein, psRNAtarget server and TargetFinder tool were used to predict unigene targets, whereas comparative genomics strategy was used for identifying EST targets. Functional annotation of the identified targets revealed that the identified miRNAs regulate mRNAs that participate in key biological and metabolic processes. Pathway enrichment analysis using KEGG database also revealed that they regulate important metabolic pathways including antibiotic biosynthesis, biosynthesis of unsaturated fatty acids, amino acids metabolism and flavonoid biosynthesis.Conclusion:The outcome of the study would aid experimental biologists to focus on these miRNAs to facilitate improved crop development and yield.

A modification is done in the patch structure by introducing an asymmetrical pentagon slot.Results:The proposed pentagonal antenna resonates at 5.7 GHz frequency. Further, modified antenna resonates at two bands. The lower band resonates at 5 GHz and having a bandwidth of 1.5 GHz. This band corresponds to C-band, which is suitable for satellite communication. The upper band is at 7.9 GHz with a bandwidth of 500 MHz. Performance parameters such as return loss, VSWR, input impedance and radiation pattern are obtained and analysed using ANSYS High- Frequency Structure Simulator. The radiation patterns obtained are directional, which are suitable for mobile communication.Conclusion:The antenna is compact in size and suitable for radar, satellite and vehicular communication.
New Approach to Modeling and Simulation of Chemical and Mass Transfer Processes in Column Apparatuses
Authors: Boyadjiev Christo , Boyadjiev Boyan 
Published: November 2018

Objective:The classical mass transfer theory is not applicable for modeling the mass transfer of chemical, absorption, adsorption and catalytic processes in column apparatuses, where the velocity distributions and interphase boundaries are unknown. The modeling of these processes is related with the creation of new type of convection-diffusion models (for qualitative analysis) and average-concentration models (for quantitative analysis), where the surface reactions are replaced by equivalent volume reaction, while the velocity and concentration distributions are replaced by average velocity and concentrations. The effect of the radial non-uniformity of the velocity in the average-concentration models is introduced by model parameters, which must be obtained experimentally.Methods:The new convection-diffusion and average-concentration models are obtained in the cases of different processes in column apparatuses: simple and complicated chemical reactions, physical and chemical absorption, physical and chemical adsorption, heterogeneous catalytic processes (physical and chemical adsorption mechanism). These models are presented in the monograph Chr. Boyadjiev, M. Doichinova, B. Boyadjiev, P. Popova-Krumova, “Modeling of Column Apparatus Processes” (Second edition), Springer- Verlag, Berlin Heidelberg, 2018.Results:Two hydrodynamic situations are considered, when the radial velocity component is equal to zero, in the cases of an axial modification of the radial non-uniformity of the axial velocity component and when the radial velocity component is not equal to zero.Conclusion:The use of experimental data, for the average concentrations at the column end, for a concrete process and column, permits to obtain the model parameters, related with the radial non-uniformity of the velocity. These parameter values permit to use the averageconcentration models for modeling of different processes.

Outcomes of elective gonadectomy procedures performed on dogs and cats by veterinary students and shelter veterinarians in a shelter environment
Authors: Kreisler Rachael E. , Shaver Stephanie L. , Holmes John H. 
Published: November 2018

Abstract
OBJECTIVE To determine complication rates for elective gonadectomy procedures performed by veterinary students on dogs and cats in an animal shelter, characterize these complications, and compare rates with those for shelter-employed veterinarians (SEVs).
DESIGN Retrospective cohort study.
ANIMALS 10,073 dogs and cats for which gonadectomy was performed by a veterinary student (n = 3,048 surgeries) or SEV (7,025 surgeries) at an urban animal shelter over a 16-month period.
PROCEDURES Electronic medical records for included dogs and cats were reviewed and data collected regarding patient signalment, duration of gonadectomy, surgeon type (student or SEV), and types of surgical complications recorded (including death or euthanasia) during the period from anesthetic induction to 72 hours after surgery. Complication and mortality rates were compared between veterinary students and SEVs.
RESULTS No significant differences were identified between students and SEVs regarding rates of overall complications for both species, minor complications for both species, major complications for both species, and overall complications for dogs or cats specifically. The most common complications were self-limiting, with no long-term consequences, for both students and SEVs. Differences in mortality rates between students and SEVs could not be definitively determined owing to low numbers of nonsurviving patients.
CONCLUSIONS AND CLINICAL RELEVANCE With judicious case selection and as a part of a surgical training program, complication rates for veterinary student–performed gonadectomy procedures for dogs and cats were no different from those for SEV-performed gonadectomy procedures. We believe such information regarding patient outcomes will allow shelter staff to make informed decisions and help them in discussions with stakeholders who may have concerns about student participation.
Laptop Versus Longhand Note Taking in a Professional Doctorate Course: Student Performance, Attitudes, and Behaviors
Authors: Desselle Shane Paul , Shane Patricia 
Published: November 2018

Objective: To determine the relationship between longhand note taking versus laptop note taking on pharmacy students’ examination performance and identify differences in attitudes and behaviors as it relates to the note taking process.
Methods: A small group of students consented voluntarily to take longhand notes, doing away with their laptops during portions of the course administered by study investigators. Analyses were conducted on block examination performance, with each student’s score on the first examination serving as a performance benchmark to assess change. Laptop and longhand note takers completed a survey regarding various aspects of their note taking attitudes and behaviors, and also included open text comments to capture qualitative experiential data.
Results: Based upon a relatively small number of participants in the longhand cohort (n=11), the differences between the groups on subsequent examinations was approximately 3.5 percentage points in favor of the longhand note-takers. There were significant differences observed between the two groups on several survey items, with longhand note takers less likely to be distracted in class and more likely to agree that other students ask to review their notes due to the quality of those notes.
Conclusions: Longhand note taking might facilitate more accurate recall or retrieval in test situations, thus producing improved test scores for certain types of students in certain types of courses; however additional research is needed. Faculty may consider whether modifying students’ classroom note taking practices may contribute to an improved learning experience.
