2017 Bangladesh Journal of Neuroscience  
Epilepsy is a common neurological disorder. Sodium valproate is one of the commonest broad spectrum antiepileptic drugs and it is used worldwide. Weight gain is the common side effect which is known to be associated with insulin resistance. The aim of this study was to see the association of sodium valproate therapy with insulin resistance among epileptic patients. Methods: It was a cross-sectional analytical study. Total 102 patients (51 epileptic patients with valproate monotherapy for at

The study was carried out from March 2016 to April 2017 for one year in the epilepsy clinic and outpatient Department of Neurology at Bangabandhu Sheikh Mujib Medical University, Dhaka. Participants underwent anthropometric evaluations and biochemical tests including fasting blood sugar and fasting insulin level. Insulin resistance (IR) index was calculated. Result: In this study mean duration of valproate treatment was 3.12±1.26 years and mean sodium valproate dose was 1133±440.5 mg/day (17.7±6.65 mg/kg/day). This study revealed serum fasting insulin level in valproate group and non-valproate group was 11.05±4.86 (ìU/ml) and 7.39±2.01 (ìU/ml) respectively. Fasting blood glucose was 4.71±0.79 (mmol/L) in valproate group and 4.41±0.62 (mmol/L) in non- valproate group. Calculated IR index in valproate group and non-valproate group was 2.17±0.55 and 1.46±0.39 respectively. IR index, fasting insulin and blood glucose all were significantly higher in valproate group than non- valproate group. This study also revealed mild positive correlation of IR index with dose and duration of valproate treatment. Conclusion: Sodium valproate treated patient had significantly higher IR index than control group. Bangladesh Journal of Neuroscience 2017; Vol. 33 (2): 63-69

Challenges in Using ctDNA to Achieve Early Detection of Cancer [article]

Imran S Haque, Olivier Elemento
2017 bioRxiv   pre-print
Early detection of cancer is a significant unmet clinical need. Improved technical ability to detect circulating tumor-derived DNA (ctDNA) in the cell-free DNA (cfDNA) component of blood plasma via next-generation sequencing and established correlations between ctDNA load and tumor burden in cancer patients have spurred excitement about the possibilities of detecting cancer early by performing ctDNA mutation detection. We reanalyze published data on the expected ctDNA allele fraction in

Instead, new approaches that integrate ctDNA mutations with multiple other blood-based analytes (such as exosomes, circulating tumor cells, ctDNA epigenetics, metabolites) as well as integration of these signals over time for each individual may be needed.

Large-Scale Chemical Informatics on GPUs [chapter]

Imran S. Haque, Vijay S. Pande
2011 GPU Computing Gems Emerald Edition  
In this chapter we present the design and optimization of GPU implementations of two popular chemical similarity techniques: Gaussian shape overlay (GSO) and LINGO. GSO involves a data-parallel, arithmetically intensive iterative numerical optimization; we use it to examine issues of thread parallelism, arithmetic optimization, and CPU-GPU transfer overhead minimization. LINGO is a string similarity algorithm that, in its canonical CPU implementation, is bandwidth intensive and branch heavy,

2018 Sustainability  
The automobile industry has significantly contributed towards China's economy. After producing approximately 24.5 million vehicles in 2015, China's automobile industry has achieved its greatest height by emerging worldwide as the top automobile producer. However, China's automobile industry could not sustain this achievement and it witnessed a sudden growth rate decrease in 2016–2017, reflecting their poor export performance. To address this problem, the prime objective of this research is to

For this reason, a quantitative research approach with cross-sectional research design was adopted by gathering the data from 347 respondents working as export managers at Chinese automobile companies via simple random technique. Partial least square structural equation modeling (PLS-SEM) through software smartPLS-3.2.7 employed to analyze data. Results revealed that the TQM, EO, EMO, BO, and CP has a significant association with FEP. Additionally, findings confirmed CP as a moderating variable that contributes positively to FEP. The research has eminently contributed to the export performance of the automobile industry, specifically in China. It is very beneficial to practitioners in the Chinese automobile industry as it will assist them in regaining and exceeding their record export performance while also contributes to resource-based-view theory.

Muhammad Imran, Talat Naseer Pasha, Muhammad Qamer Shahid, Imran Babar, Muhammad Naveed ul Haque
2016 Asian-Australasian Journal of Animal Sciences  
Objective: The objective of the study was to determine the effects of increasing levels of meta bolizable protein (MP) on lactation performance and nitrogen (N) efficiencies in lactating dairy cows. Methods : Nine multiparous cows in mid lactation [113±25 days in milk] received three treat ments in a 3×3 Latin square design with a period length of 21 days. The treatments were three diets, designed to provide similar energy and increasing supply of MP (g/d) (2,371 [low], 2,561 [medium], and

Results: Increasing MP supplies did not modify dry matter intake, however, it increased milk protein, fat, and lactose yield linearly. Similarly, fat corrected milk increased linearly (9.3%) due to an increase in both milk yield (5.2%) and milk fat content (7.8%). No effects were observed on milk protein and lactose contents across the treatments. Milk nitrogen efficiency (MNE) decreased from 0.26 to 0.20; whereas, the metabolic efficiency of MP decreased from 0.70 to 0.60 in low to high MP supplies, respectively. The concentration of blood urea nitrogen (BUN) increased linearly in response to increasing MP supplies. Conclusion: Increasing MP supplies resulted in increased milk protein yield; however, a higher BUN and low MNE indicated an efficient utilization of dietary protein at low MP supplies.

SSCM: A method to analyze and predict the pathogenicity of sequence variants [article]

Sharad Vikram, Matthew D Rasmussen, Eric A Evans, Imran S Haque
2015 bioRxiv   pre-print
The advent of cost-effective DNA sequencing has provided clinics with high-resolution information about patients' genetic variants, which has resulted in the need for efficient interpretation of this genomic data. Traditionally, variant interpretation has been dominated by many manual, time-consuming processes due to the disparate forms of relevant information in clinical databases and literature. Computational techniques promise to automate much of this, and while they currently play only a

Here, we present SSCM-Pathogenic, a genome-wide, allele-specific score for predicting variant pathogenicity. The score, generated by a semi-supervised clustering algorithm, shows predictive power on clinically relevant mutations, while also displaying predictive ability in noncoding regions of the genome.

Gabriel A. Lazarin, Imran S Haque, Eric A Evans, James D. Goldberg
2016 bioRxiv   pre-print
Objective: To tabulate individual allele frequencies and total carrier frequency for Smith-Lemli-Opitz syndrome (SLOS) and compare expected versus observed birth incidences. Design: Retrospective analysis of patients from the general population who have undergone carrier screening for SLOS. Setting: Individuals were offered and elected carrier screening in their respective physician's offices. Patients: 262,399 individuals with no indication of family or personal history of Smith-Lemli-Opitz
more » ... drome, primarily US-based, screened for Smith-Lemli-Opitz syndrome mutations as part of an expanded carrier screening panel. Intervention(s): Data on mutations in the DHCR7 gene causing SLOS were analyzed to estimate carrier frequencies in multiple ethnic groups. SLOS birth incidences obtained from existing literature are then compared to our data to estimate the effect of SLOS on fetal survival. Main Outcome Measure(s): Individual and cumulative allele frequencies stratified by self-reported patient ethnicity. Results: SLOS carrier frequency is highest in individuals of Ashkenazi Jewish ancestry (1 in 43) and Northern Europeans (1 in 54). Comparing predicted birth incidence to that observed in published literature suggests that approximately 42% to 88% of affected conceptuses experience fetal demise. Conclusion: SLOS is relatively frequent in certain populations and, due to its impact on fetal survival, merits preconception screening.
