M. Davani Rad,N. Ghaleh Golab Behbahan,G. Moazeni Jula
International Journal of Animal and Veterinary Advances , 2012,
Abstract: Newcastle Disease (ND) is an acute, highly contagious viral disease in poultry. Despite the intensive vaccination programs to control Newcastle Disease Virus (NDV), the recent infection of NDV in Iran has led to severe morbidity and mortality in Chukar Partridges. The aim of this study was to investigate the ability of Inactivated Oil Adjuvant Vaccine (IOAV) following use of live vaccine to have better protection in Chukar Partridges against ND. Three hundred Chukar Partridges were divided in to 5 groups. The groups were vaccinated according to following program: I-vaccinated with B1 strain of NDV via drinking water at five weeks of age; group II-vaccinated in the same mode as group I with B1 live vaccine and revaccinated at seven weeks of age with la Sota strain of NDV via drinking water; group III-vaccinated at five weeks of age with strain B1 live vaccine given by drinking water in combination with IOAV vaccine administered subcutaneously at the nape of each bird; group IV-vaccinated at five weeks of age with B1 by eye drop in combination with IOAV vaccine also administered as in group III; and group V-not vaccinated. All groups were reared in the same conditions. At 17 weeks of age, all Chukar Partridges were challenged with Hertz 33/56 strain of NDV. All the Chukar Partridges in group V died, indicating that there was no disease resistance of this unvaccinated control group of Chukar Partridges. The disease resistance of chukar Partridges in the vaccine groups (100.00) was significantly different from that of the control group (0.00) (p<0.001). The mean antibody titers between all groups were significantly different (p<0.001). In the groups that vaccinated simultaneously with B1 live vaccine and IOAV, the enhancement of titers was meaningful in comparison to the groups that received only lived vaccines.

International Journal of Poultry Science , 2008,
Abstract: The in vitro activities of aivlosin tylosin tiamulin, erythromycin, oxytetracycline, spectinomycin, lincomycin, lincomycin-spectinomycin (1:2) and enrofloxacin were determined against twenty-eight isolates of Mycoplasma gallisepticum and 4 isolates of Mycoplasma synoviae using microbroth dilution method. The isolates showed various susceptibilities to antimicrobial agents. Aivlosin, lincomycin-spectinomycin (1:2), tylosin, tiamulin, enrofloxacin and also lincomycin were commonly more effective against these field isolates. However, aivlosin was the most effective drugs against Mycoplasma gallisepticum and Mycoplasma synoviae as its MIC was the lowest of all. Oxytetracycline, erythromycin and spectinomycin were not effective against all isolates, as their MICs for some of isolates were extremely high. The MIC of erythromycin and oxytetracycline were distributed across a broad range. Resistant strains to two mentioned antibiotics were obtained from the field.

Research Journal of Biological Sciences , 2012,
Abstract: Although, deaths due to asthma usually happen out of the hospital, but high risk children may be identified upon their previous medical history before admission toPediatric Intensive Care Unit (PICU). Patients who do not respond considerably to primary treatments in emergency department must be transferred to PICU for close observation, monitoring and further treatment. According to burden of asthma and its fatality if not be classified or treated properly, the early recognition of high-risk asthmatic children who must be admitted to PICU and to avoid unnecessary admissions, play a significant role in management of asthma, therefore we planned this study to identify predictive factors of PICU admission for asthmatic children. This comparative (analytical) and cross-sectional study on 70 asthmatic children (40 patients admitted to ward and 30 patients to PICU) carried out to determine epidemiologic and clinical factors, laboratory and radiologic findings and treatments in 2 groups of patients, who admitted to PICU versus respiratory ward. Statistical tests including t-test and Chi-square were used to analyze and compare results between these groups. This study revealed some statistically significant difference in presenting clinical signs such as Cyanosis (p = 0.0001), Tachypnea (p = 0.04) and Tachycardia (p = 0.01) between 2 groups of patients, who admitted to PICU versus respiratory ward. Besides, there were some meaningful differences in their laboratory findings, including lower PaO2 (p = 0.03) and higher PaCO2 (p = 0.02) in patients admitted to PICU than who admitted to ward. Previous positive history of PICU admission and/or inappropriate medical treatment was more common in PICU admitted patients than ward admitted group. We concluded that cyanosis, rapid respiratory and pulse rates, low PaO2, high PaCO2, previous positive history of PICU admission and inappropriate medical treatment, all prepare an asthmatic patient to need PICU readmission.

PICU EXTUBATION FAILURE: THE ROLE OF NEUROMUSCULAR DISORDERS
N. Billan MD,,A.G. Behbahan MD
Iranian Journal of Child Neurology , 2007,
Abstract: ObjectiveNeuromuscular disorders (diseases of the motor unit), can cause respiratory problems such as impaired cough reflex, chest deformity, recurrent pneumonia and acute respiratory failure; these are the worst most common complications of these diseases and the leading cause of death in such patients (1, 2). Their management hence, very often, entails admission to the Pediatric Intensive Care Unit (PICU) (3,4) and during this phase, endotracheal intubation is almost always necessary, to maintain the patency of airways and to apply Positive Pressure Ventilation (PPV). However, endotracheal intubation is always temporary, and its success or failure depends on the timely decision of its termination to restore the normal respiration or to avoid the risk of recurring respiratory failure (5, 6). We designed this study to evaluate the role of neuromuscular disorders in causing extubation failure as compared to that of other risk factors.Materials & MethodsIn an analytical cross-sectional study, the risk factors of reintubation and duration of mechanical ventilation in two groups of 30 patients each, was compared, the first successful extubation and the second with extubation failure.ResultsNeuromuscular disorders (including Spinal Muscular Atrophy, Guillain- Barre' Syndrome, Congenital Myopathies and Muscular Dystrophies) were the main underlying diseases in extubation-failure group (P= 0.0002). Hypercapnia (PaCO2>50mmHg) was shown to be the most common cause of both the first intubation (P=0.001) and reintubation (P=0.004) in the group of patients who failed extubation. The mean duration of intubation and mechanical ventilation was longer in patients with neuromuscular disorders who had extubation failure (P= 0.01).ConclusionThis study showed that, as underlying problems, neuromuscular disorders are the most common causes of prolonged intubation which defeat weaning from the ventilator and result in reintubation by inducing hypercapnia. Therefore the weaning process needs to be done gradually in these patients, and in conjunction with supportive measures, such as close observation for at least for 72 hours following extubation to monitor any possibility of recurrence of hypercapnic respiratory failure.
A Complexity Separation Between the Cache-Coherent and Distributed Shared Memory Models
Wojciech Golab
Computer Science , 2011,
Abstract: We consider asynchronous multiprocessor systems where processes communicate by accessing shared memory. Exchange of information among processes in such a multiprocessor necessitates costly memory accesses called \emph{remote memory references} (RMRs), which generate communication on the interconnect joining processors and main memory. In this paper we compare two popular shared memory architecture models, namely the \emph{cache-coherent} (CC) and \emph{distributed shared memory} (DSM) models, in terms of their power for solving synchronization problems efficiently with respect to RMRs. The particular problem we consider entails one process sending a "signal" to a subset of other processes. We show that a variant of this problem can be solved very efficiently with respect to RMRs in the CC model, but not so in the DSM model, even when we consider amortized RMR complexity. To our knowledge, this is the first separation in terms of amortized RMR complexity between the CC and DSM models. It is also the first separation in terms of RMR complexity (for asynchronous systems) that does not rely in any way on wait-freedom---the requirement that a process makes progress in a bounded number of its own steps.
Deconstructing Queue-Based Mutual Exclusion
Wojciech Golab
Computer Science , 2013,
Abstract: We formulate a modular approach to the design and analysis of a particular class of mutual exclusion algorithms for shared memory multiprocessor systems. Specifically, we consider algorithms that organize waiting processes into a queue. Such algorithms can achieve O(1) remote memory reference (RMR) complexity, which minimizes (asymptotically) the amount of traffic through the processor-memory interconnect. We first describe a generic mutual exclusion algorithm that relies on a linearizable implementation of a particular queue-like data structure that we call MutexQueue. Next, we show two implementations of MutexQueue using O(1) RMRs per operation based on synchronization primitives commonly available in multiprocessors. These implementations follow closely the queuing code embedded in previously published mutual exclusion algorithms. We provide rigorous correctness proofs and RMR complexity analyses of the algorithms we present.
Effects of Mothers Type of Feeding During Their Infancy on Their Infants Feeding

Pakistan Journal of Social Sciences , 2012,
Abstract: A woman`s attitude towards breastfeeding and how she chooses to feed her baby are closely linked to the woman`s culture. In evaluating the cultural impact on breastfeeding, one can ask the woman about where she grew up and if her mother, aunts or friends have breastfed a baby and what support from family or friends they had. Although, it has been generally accepted that breastfeeding has valuable effects on nutritional, immunological and emotional aspects of infants health. However, the tendency of some mothers toward bottle-feeding should not be denied, therefore we planned this study to find out how families cultural factors and specially previous feeding of mothers during their infancy can influence their adherence to breastfeeding of their infants. This is a cross-sectional and analytical study on 200 healthy infants at the age of 5 to 6 months who had come in Infants Growth-Surveillance Clinic of Tabriz Children s Hospital (affiliated to Tabriz University of Medical Sciences) during one year from March 2005 to March 2006. The eligible infants were consecutively enrolled and allocated in two groups upon their type of feeding: breastfed versus bottle-fed, every volunteer mother passed an interview with a trained medical staff that gathered and recorded the needed data by completing a questionnaire. Selection and allocation of participants was terminated for each group when it reached to a total number of 100 infants. Total 72% of mothers in breastfed group themselves had received breastfeeding during infancy, while only 41% of mothers in bottle-fed group had previous history of being breastfed. This difference is statistically significant: p = 0.0001, it shows a meaningful correlation between mothers` feeding during their infancy and their decision in choosing the feeding method of their own infants.The most important causative factors for beginning of bottle-feeding in this study was revealed to be lack of maternal motivation for breastfeeding (reported in 69% of mothers of bottle-fed infants) and also physicians` prescription of formula (in 22%). Breastfeeding rates can be increased by appropriate cultural background and skilled lactation support, worksite facilities for breastfeeding mothers, accommodation for human-milk feeding in child care settings and appropriate legislation.

Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.411207
Abstract: The main goal of the present research is to realize a sensitivity analysis of the developed complex micro scale austenite (γ) to ferrite (α) phase transformation model. The proposed solution is implemented in the developed Cellular Automata Framework that facilitates implementation of various microstructure evolution models. Investigated model predicts phase transformation progress starting from the fully austenitic or two-phase regions. Theoretical background of the implemented austenite-ferrite phase transformation model is presented in the paper. The defined transition rules for initiation and subsequent growth as well as internal variables for each particular CA cell are also discussed. Examples of results obtained from the developed model, as well as model capabilities are shown. Finally sensitivity analysis using Morris OAT Design is also presented and discussed.
Immunogenicity of Neonatal BCG Vaccination in Children Entering Primary School

Pakistan Journal of Biological Sciences , 2008,
Abstract: This study has been designed to evaluate the immunogenicity of neonatal BCG-vaccination in children at the age of 7 to 8 years, by skin test using Purified Protein Derivative (PPD), as BCG vaccination at birth is a part of routine program of immunization in our country, Iran; we decided to study its efficacy and also tried to determine if there is any correlation between PPD-test results and BCG scar size. This is a comparative study on 150 children (94 males and 56 females) at the age of 7 to 8 years, who possess neonatal-BCG scar. They were chosen from several primary schools in Tabriz-Iran, by simple random sampling and tested with 0.1 mL of 5-unit-PPD solution (a product of Iran Institute of Razi); then observations recorded. The average diameter of BCG scars were 7.03 mm in girls, 5.45 mm in boys and 6.05 for all. The diameter of induration area resulted from PPD-test after 72 h was less than 5 mm in 95.33% and 5-9 mm in 4.66% of studied children; there was no case with induration area of 10 mm or more at all. Every child who developed an induration area of 5 mm or more by PPD test, had a BCG scar with the diameter of 5 mm or more. There was a statistically meaningful direct correlation between sizes of neonatal-BCG scar and diameter of induration area after PPD-test (r = 0.21 and p = 0.008). This study shows that reactivity to PPD test (and probably immunity against tuberculosis) decreases as age increases; therefore it seems to be necessary to repeat BCG-vaccination in children at the age of entering primary school.
