  1. Book ; Online: Analysis and object oriented implementation of the Kovacic algorithm

    Abbasi, Nasser M.

    2022  

    Abstract: This paper gives a detailed overview and a number of worked out examples illustrating the Kovacic \cite{Kovacic86} algorithm for solving second order linear differential equation ${A(x) y"+ B(x) y' + C(x) y=0}$ where $A,B,C$ are rational functions with ... ...

    Abstract This paper gives a detailed overview and a number of worked out examples illustrating the Kovacic \cite{Kovacic86} algorithm for solving second order linear differential equation ${A(x) y"+ B(x) y' + C(x) y=0}$ where $A,B,C$ are rational functions with complex coefficients in the independent variable $x$. All three cases of the algorithm were implemented in a software package based on an object oriented design and complete source code listing given in the appendix with usage examples. Implementation used the Maple computer algebra language. The complete Kovacic package in one mpl file accompany the arXiv version of this paper. This package was then used to analyze the distribution of Kovacic algorithm cases on $3000$ differential equations

    Abstract Objectives: Alzheimer's disease (AD), the most common cause of dementia, is one of the leading causes of morbidity and death in the world. Currently, treatment mostly used to slow down the disease progression. Herbal remedies are considered by many in the community as a natural and safe treatment with fewer side effects. Silibinin, the active ingredient of
    Materials and methods: Forty eight male Wistar rats were randomly divided into sham, lesion; Aβ
    Results: Different concentrations of silibinin improved behavioral performance in animals. Higher doses of Silibinin could improve memory and learning function through MWM. Also, increasing the concentration of silibinin resulted in decreased ROS and NO production in a dose-dependent manner.
    Conclusion: Consequently, silibinin may act as a potential candidate for alleviating symptoms of AD.

    Abstract Objective: Red reflex test is an effective screening tool in the early diagnosis of neonatal eye abnormalities. The aim of this study was to detect the sensitivity and specificity of red reflex assessment in neonates, performed by pediatricians (or other care providers) in comparison with ophthalmologists. Also association between red reflex findings and neonatal variables is evaluated.
    Methods: By a prospective study all neonates born from July 2011 until March 2012 in Mustafa Hospital, a general teaching hospital in Ilam city, Iran, were evaluated. Neonates were firstly investigated by pediatrician in substandard conditions at the first day of birth and several days later by ophthalmologist in standard conditions.
    Findings: Totally 255 neonates including 141 boys and 114 girls were investigated, 144 of whom were born by cesarean section. There was a significant relationship between method of childbirth (72.9% disorders in CS vs 56.8% in vaginal delivery (P<0.007)), duration of delivery (disorders in prolonged: 100% and 11.8% vs no prolonged: 56.8% and 6.3% in standard and non standard conditions respectively (P<0.0001)), difficult delivery (98.6% disorders vs 6.5% in standard and non standard conditions respectively (P<0.01)) and increase or decrease of red reflex sensitivity test. A significant difference (identification of ophthalmic problems) was seen among neonates' inspections in primary hours and substandard conditions compared to further inspections in standard conditions particularly from 3(rd) day of birth.
    Conclusion: Due to a considerable difference between the results of ophthalmic examination of neonates in different conditions, red reflex examination by pediatricians is suggested for all neonates to early identification of ophthalmic problems at the first step. It is also suggested a red reflex screening for all neonates before being discharged from hospital as well as 6 weeks later and in case of any problem to be referred to ophthalmologist.
