Effectiveness of Developmental Therapy in Children with Cerebral Palsy
Khondoker Ehsanul Arefin,Mizanur Rahman,Kanij Fatema 아시아지적장애인연맹 산하 아시아저널센터 2018 Asia-Pacific Journal of Intellectual Disabilities Vol.5 No.2
Cerebral palsy (CP) describes a group of motor syndromes resulting from disorders of early brain development. Physiotherapy is an important part of the management of children with CP. In Bangladesh a single approach therapy has been adopted in any medical institutes as developmental therapy where a developmental therapist assesses the child and provides physiotherapy, occupational therapy, cognitive stimulation, feeding therapy, speech and language therapy to the children according to the need by a holistic approach. There are limited published evidences on effectiveness of developmental therapy among Bangladeshi children with cerebral palsy. So this study was designed to measure the effectiveness of developmental therapy in children with cerebral palsy. A quasi-experimental study was conducted in the department of Pediatrics of Bangabandhu Sheikh Mujib Medical University from February 2009 to May 2010 on 135 children with CP aged 6 months to 3 years. The motor, mental and behavioral functions of the selected children were initially measured by Bayley Scales of Infant Development II. They were reassessed after 3 months and 6 months following developmental therapy. Only 62 (45.9%) children have completed the 2 follow up sessions and hence were evaluated against their baseline motor, mental and behavior score. The study result showed that motor, mental and behavior functions were significantly improved after 6 months following developmental therapy. Nearly half (46.8%) of the children improved on motor skills, 40.3 on mental skills and about 69% on behavior skills. Epilepsy and duration of therapy at home interfered developmental outcome. This study has demonstrated a beneficial effect of single approach developmental therapy for children with cerebral palsy.

Probiotics may offer a safe intervention for diarrheal diseases. The aim of the present study was the assessment of the antidiarrheal property of probiotic bacteria. For their antidiarrheal efficacy assessment, yogurt was prepared using the isolated bacteria from selective regional yogurt of Bangladesh, and mice model trails were conducted using castor oil induced diarrheal mice. The probiotic treatment was applied on three mice groups, each having 6 mice and their respective doses were 50 mL/kg body weight in treatment group (TG) 1, 100 mL/kg body weight in TG2, and 150 mL/kg body weight in TG3. A four week treatment of probiotic significantly (P<0.001) reduced the percentage (67.37%) of diarrhea in TG3 (150 mL yogurt/kg body weight). All the treatment groups showed a significant (P<0.001) increase in the latent periods, reduced the total fecal output, and frequency and fecal water content compared to the negative control group. Serum electrolytes (Na<SUP>+</SUP> and K<SUP>+</SUP>) and total protein levels were higher in the TG3 compared to the negative control group. Further research regarding molecular characterization and identification of specific genes and proteins of interest may help to develop the next generation bacteriocins and antidiarrheal drugs.
Molecular Characterization of Selected Local and Exotic Cattle Using RAPD Marker
Khatun, M. Mahfuza,Hossain, Khondoker Moazzem,Rahman, S.M. Mahbubur Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.6
In order to develop specific genetic markers and determine the genetic diversity of Bangladeshi native cattle (Pabna, Red Chittagong) and exotic breeds (Sahiwal), randomly amplified polymorphic DNA (RAPD) analysis was performed using 12 primers. Genomic DNA was extracted from 20 cattle (local and exotic) blood samples and extracted DNA was observed by gel electrophoresis. Among the random primers three were matched and found to be polymorphic. Genetic relations between cattle's were determined by RAPD polymorphisms from a total of 66.67%. Statistical analysis of the data, estimating the genetic distances between cattle and sketching the cluster trees were estimated by using MEGA 5.05 software. Comparatively highest genetic distance (0.834) was found between RCC-82 and SL-623. The lowest genetic distance (0.031) was observed between M-1222 and M-5730. The genetic diversity of Red Chittagong and Sahiwal cattle was relatively higher for a prescribed breed. Adequate diversity in performance and adaptability can be exploited from the study results for actual improvement accruing to conservation and development of indigenous cattle resources.
Review of Microwave Assisted Manufacturing Technologies
김재환,문성철,고현우,김기백,Mohammad Abu Hasan Khondoker,Lindong Zhai 한국정밀공학회 2012 International Journal of Precision Engineering and Vol.13 No.12
This paper reviews recent advancement of microwave (MW) assisted manufacturing technologies. Because MW energy interacts with materials in unique ways, MW assisted manufacturing technologies have the potential to develop entirely new or enhanced manufactured products and materials as well as new approaches for producing such materials. There have been various fields MW technologies have been applied: material processing of ceramics, polymers, metals, carbon nanotubes and composites; machining;synthesis of organic and inorganic compounds; waste remediation and environmental applications; solvent extraction from foods and bioproducts. This review introduces some fundamental knowledge of MW and current status of MW applications focusing on manufacturing technologies. Also, some suggestions for future research are addressed.
Improvement in DRX Power Saving for Non-real-time Traffic in LTE
Mohammad Tawhid Kawser,Mohammad Rakibul Islam,Khondoker Ziaul Islam,Mohammad Atiqul Islam,Mohammad Mehadi Hassan,Zobayer Ahmed,Rafid Hasan 한국전자통신연구원 2016 ETRI Journal Vol.38 No.4
A discontinuous reception (DRX) operation is included in the Long Term Evolution (LTE) system to achieve power saving and prolonged battery life of the user equipment. An improvement in DRX power saving usually leads to a potential increase in the packet delay. An optimum DRX configuration depends on the current traffic, which is not easy to estimate accurately, particularly for non-real-time applications. In this paper, we propose a novel way to vary the DRX cycle length, avoiding a continuous estimation of the data traffic when only non-real-time applications are running with no active real-time applications. Because a small delay in non-real-time traffic does not essentially impact the user’s experience adversely, we deliberately allow a limited amount of delay in our proposal to attain a significant improvement in power saving. Our proposal also improves the delay in service resumption after a long period of inactivity. We use a stochastic analysis assuming an M/G/1 queue to validate this improvement.

Ismet Ara Jahan,Md. Hemayet Hossain,Khondoker Shahin Ahmed,Zakia Sultana,Pizush Kanti Biswas,Katrun Nada 경희대학교 융합한의과학연구소 2018 Oriental Pharmacy and Experimental Medicine Vol.18 No.4
The present research evaluates the phytochemical and antioxidant activity of Moringa oleifera Lam. seed kernel grown in Bangladesh. M. oleifera seed kernel was extracted with methanol, acetone and water individually. The phytochemical content was evaluated through the determination of total phenolic, total flavonoid and total tannin contents. In vitro antioxidant capacity was determined following four complementary methods: DPPH (2,2-diphenyl-1-picrylhydrazyl, ABTS{2,2′-azinobis- (3-ethylbenzothiazoline-6-sulfonic acid)}, and NO (nitric oxide) free radical scavenging and reducing power tests. The total phenolic contents 60.99 ± 0.153, 30.78 ± 0.101 and 90.97 ± 0.134 mg gallic acid eq./g dry extract, total flavonoids contents 10.13 ± 0.171, 13.32 ± 0.101 and 221.76 ± 0.221 mg quercetin eq./g and total tannins contents 97.10 ± 0.153, 73.91 ± 0.107 and 21.74 ± 0.086 mg tannic acid eq./g dry extract were found to be present in methanol, acetone and water extracts respectively. Among the three extracts, the water extract exhibited significant activities for scavenging DPPH, ABTS and NO free radicals with EC50 values 36.89 ± 0.154, 13.20 ± 0.049 and 217.95 ± 0.327 μg/mL respectively against the standard antioxidant compound ascorbic acid and butylated hydroxy anisole. The results of this research revealed that among the three extracts of M. oleifera seed kernel the water extract exhibited significant free radical scavenging activity. Reducing power, total phenolic and total flavonoid contents were also observed to be significant for the water extract. So in contrast of all the results of this study it can be concluded that among the three extracts (methanol, acetone and water) the water extract possessed potent antioxidant activity which support the use of M. oleifera seed kernel as natural antioxidant.
