Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by cognitive impairments in the initial stage, which lead to severe cognitive dysfunction in the later stage. Action observation therapy (AOT) is a multisensory cognitive rehabilitation technique where the patient initially observes the actions and then tries to perform. The study aimed to examine the impact of AOT along with usual physiotherapy interventions to reduce depression, improve cognition and balance of a patient with AD. A 67 years old patient with AD was selected for this study because the patient has been suffering from depression, dementia, and physical dysfunction along with some other health conditions like diabetes and hypertension. Before starting intervention, a baseline assessment was done through the Beck Depression Inventory (BDI) tool, the Mini-Cog Scale, and the Berg Balance Scale (BBS). The patient received 12 sessions of AOT along with usual physiotherapy interventions thrice a week for four weeks, which included 45 minutes of each session. After four weeks of intervention, the patient demonstrated significant improvement in depression, cognition, and balance, whereas the BDI score declined from moderate 21/63 to mild 15/63 level of depression. The Mini-Cog score improved from 2/5 to 4/5, and the BBS score increased from 18/56 to 37/56. It is concluded that AOT along with usual physiotherapy intervention helps to reduce depression, improve cognition and balance of people with AD.

A New Approach of Solving Linear Fractional Programming Problem (LFP) by Using Computer Algorithm

引用

Open Journal of Optimization 2015年第3期4卷 74-86页

作者： Sumon Kumar Saha Md.

In this paper, we study a new approach for solving linear fractional programming problem (LFP) by converting it into a single Linear Programming (LP) Problem, which can be solved by using any type of linear fractional programming technique. In the objective function of an LFP, if βis negative, the available methods are failed to solve, while our proposed method is capable of solving such problems. In the present paper, we propose a new method and develop FORTRAN programs to solve the problem. The optimal LFP solution procedure is illustrated with numerical examples and also by a computer program. We also compare our method with other available methods for solving LFP problems. Our proposed method of linear fractional programming (LFP) problem is very simple and easy to understand and apply.

In light of the use of Lannea barteri in the management of diverse illnesses and treatment of wounds in traditional medicine, the current study was conducted to assess the wound-healing efficacy of crude aqueous extract of the stem bark of Lannea barteri and its shea butter formulated ointment using an excision wound model in the rabbit. The herbal ointment (5%, w/w) exhibited a significant wound healing activity, showing 99.9% ± 0.3% wound contraction at the end of the experiment (24th day). There was no significant difference (p > 0.05) between the 5% (w/w) herbal ointment compared with Silver Sulphadiazine cream (positive control), which showed a 97.8% ± 1.0% rate of excision wound contraction on day 24. Compared with the negative control group (administered with only shea butter), the wound healing activity of the ointment was significant (p Lannea barteri for the treatment of wounds and demonstrates that shea butter usage as a base in formulating an herbal ointment might aid in topical application for wound repair and regeneration, as well as the potential for enhanced wound healing.
