Comparative study of haemagglutination inhibition, Agar gel precipitation test, Serum neutralization and Enzyme linked immunosorbent assay for detection to avian influenza viruses  [PDF]
Shahid Faraz, Muhammad Abubakar, Mohammad Farooque, Sarfaraz Ali Fazlani, Ghluam Hussain Jaffar
Health (Health) , 2010, DOI: 10.4236/health.2010.22016
Abstract: The sensitivity, specificity and reproducibility of the serological tests for detection of avian in-fluenza viruses were carried-out by using Ham- agglutination inhibition (HI), Agar gel precipita-tion test (AGPT), and Enzyme linked immu-nosorbent assay (ELISA) and Serum neutraliza-tion test. The geometric mean titre (GMT) of hae- magglutination inhibition antibodies recor- ded as log2 indicated that the post vaccination titres in the field were on higher side i.e., 7.9 for H7 and 5.9 for H9. The correlation between HI titre and AGPT affirmed that for the AGPT test need high antibody titre for positive reaction. The pooled sera were also used to correlate the se-rum neutralization test and enzyme linked im- muno-sorbent assay. The serial two fold dilute- ons were tested for the serum neutralization ac- tivity and concluded that the HI titre log2 4 pro-vided 100% protection, than 52% and 45% pro-tection in 1:2 and 1:4 dilution was recorded, respectively. Similarly, the ELISA test showed positive results up to 1:16 HI titre, i.e. log2 4 and confirmed the linear relation between these two serological tests. In HI test, the concentration of antigen can influence the result. It also needs careful preparation of concentration of eryth-rocyte suspension. Agar Gel immuno-diffusion is basically a qualitative test as it can not de-termine the quantity of antigen or antibody with the help of this test. It lacks the level of sensi-tivity as offered by other test. If serum neutrali-zation test is performed on a pooled serum sam- ples, then it could lead to a false conclusion on antibodies status. ELISA is most sensitive, spe-cific and accurate as compare to all other sero-logical tests.

Faraz Mojab,Bahman Nickavar
Iranian Journal of Pharmaceutical Research , 2003,
Abstract: The essential oil of the root of Heracleum persicum (Apiaceae) was analyzed by capillary GC and GC /MS. The major constituents were identified as viridiflorol (23.05 %), elemol (3.63 %), β-maliene (3.07 %), spathulenol (3.34 %) and 2-tetradecanol (3.38 %).
A Meta Model to Optimally Design the VSI T2 Control Chart
A. Faraz,A. Seif
International Journal of Applied Operational Research , 2011,
Abstract: Recent studies have shown that the variable sampling interval (VSI) scheme helps practitioners to detect process shifts more quickly than the classical scheme (FRS). In this paper, the economically and statistically optimal design of the VSI T 2 control chart for monitoring the process mean vector is investigated. The cost model proposed by Lorenzen and Vance [1] based on the Markov chain approach is modified as the objective function which is intended to be minimized through a genetic algorithm (GA) approach. Then, the effects of the costs and operating parameters on the optimal design (OD) of the chart parameters; and resulting operating loss through a fractional factorial design is systematically studied and finally, based on the ANOVA results, a Meta model to facilitate implementation in industry is proposed to determine the OD of the VSI T control chart parameters from the process and cost parameters. Keywords: Hotelling’s T 2 Control Chart, Variable Sampling Interval (VSI) Scheme, Economic Statistical Design (ESD), Markov Chain, Genetic Algorithm (GA).
A Novel Nanometric Reversible Signed Divider with Overflow Checking Capability
Faraz Dastan,Majid Haghparast
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: One of the best approaches for designing future computers is that we use reversible logic. Reversible logic circuits have lower power consumption than the common circuits, used in computers nowadays. In this study we propose a new reversible division circuit. This reversible division circuit is signed divider and has an overflow checking capability. Among the designed and proposed reversible division circuits, our proposed division circuit is the first reversible signed divider with overflow checking capability which has been designed. In this circuit we use some reversible components like reversible parallel adder, reversible left-shift register, reversible multiplexer, reversible n-bit register and reversible n-bit register with parallel load line. In this paper all the scales are in the nanometric area.
Response to rituximab in a refractory case of thrombotic thrombocytopenic purpura associated with systemic lupus erythematosus
Niaz Faraz,Aleem Aamer
Saudi Journal of Kidney Diseases and Transplantation , 2010,
Abstract: Thrombotic thrombocytopenic purpura (TTP) is a serious disorder with a significant morbidity and mortality. Majority of cases of TTP are idiopathic, but some cases may be secon-dary to connective tissue diseases. TTP has been rarely associated with systemic lupus erythe-matosus (SLE) and may be refractory to treatment with plasma exchange, requiring immuno-suppressive therapy. We describe a patient with TTP and SLE who was refractory to plasma exchange and corticosteroids but responded to anti-CD20 antibody rituximab with continued re-mission after eight months of follow-up. Rituximab appears to be an effective treatment in re-fractory cases of TTP associated with SLE.
Towards Learning free Naive Bayes Nearest Neighbor-based Domain Adaptation
Faraz Saeedan,Barbara Caputo
Computer Science , 2015,
Abstract: As of today, object categorization algorithms are not able to achieve the level of robustness and generality necessary to work reliably in the real world. Even the most powerful convolutional neural network we can train fails to perform satisfactorily when trained and tested on data from different databases. This issue, known as domain adaptation and/or dataset bias in the literature, is due to a distribution mismatch between data collections. Methods addressing it go from max-margin classifiers to learning how to modify the features and obtain a more robust representation. Recent work showed that by casting the problem into the image-to-class recognition framework, the domain adaptation problem is significantly alleviated \cite{danbnn}. Here we follow this approach, and show how a very simple, learning free Naive Bayes Nearest Neighbor (NBNN)-based domain adaptation algorithm can significantly alleviate the distribution mismatch among source and target data, especially when the number of classes and the number of sources grow. Experiments on standard benchmarks used in the literature show that our approach (a) is competitive with the current state of the art on small scale problems, and (b) achieves the current state of the art as the number of classes and sources grows, with minimal computational requirements.
Sickle Injury to Brain  [PDF]
Mubashshir Ali, Apoorva Kumar, Osman Musa Hingora, Faraz Ahmad
Open Journal of Modern Neurosurgery (OJMN) , 2015, DOI: 10.4236/ojmn.2015.51004
Abstract: We reported a case of a 12-year-old girl child with an uncommon intracranial metallic foreign body who was hit by her younger sister with sickle that got stuck to skull. Patient presented to us with stuck sickle in her head and was fully conscious with complaint of headache. She was very much afraid of her injury and was screaming with pain and fear. There was no neurological weakness. Computed tomography scan revealed that metallic foreign body was located adjacent to the confluence of major sinuses posteriorly on her skull. The location and position of foreign body suggested that it was of low velocity, and was hit from pointed end of sickle. It was taken out after doing craniectomy all around the sickle point and dural tear was repaired with pericranium. The postoperative course was uneventful.
