The Social Determinants of Organ Trafficking: A Reflection of Social Inequity
Debra A. Budiani,Kabir Karim
Social Medicine , 2008,
Abstract: Organ trafficking has become evident in its global scope and consequences. Poverty, vulnerability, destitution and a system of exploitative transplant practices are social determinants for commercial living organ donation. Guided by the WHO resolution on organ transplants and the Istanbul Declaration, transplant practices can advanced standards of greater social equality rather than exploit social determinants of poverty, vulnerability and destitution by way of exploitative health systems.
Effect of Potassium on Salinity Tolerance of Mungbean (Vigana radiata L. Wilczek)
M.E. Kabir,M.A. Karim,M.A.K. Azad
Journal of Biological Sciences , 2004,
Abstract: It is established that salinity disturbs mungbean plant growth by creating nutrient imbalance and disturbance in plant water relations. This study was undertaken to observe whether external application of K mitigates the harmful effect of salinity. Mungbean plant (var. BARI mung 3) was grown in pot at three levels of K viz. 14, 40 and 60 kg ha ha-1 under 0 and 75 mM NaCl saline conditions. Salinity decreased seriously relative water content and water retention capacity, while increased water saturation deficit and water uptake capacity. Salinity also decreased xylem exudation rate and leaf water potential. Application of higher amount of K improved the plant water relationship in mungbean plant. Salinity disturbed dry matter distribution in different plant parts as well decreased total dry matter. Similarly yield and yield contributing characters were also seriously affected by salinity, except number of seeds per pod. Application of different levels of potassium did not influence on dry matter production. However, yield and yield contributing characters were improved to some extent with the increasing levels of K. Salinity decreased significantly the uptake of N, P, K and Ca, while increased Na uptake several fold. Mg accumulation was unchanged due to salinity. K doses had no significant influence on nutrient uptake by mungbean plant, though the uptake of most of the nutrients showed an increasing tendency with the increased levels of K application. It was concluded that application of higher levels of K improves water relations as well as growth and yield of mungbean under mild level of saline conditions.

Gilchrist Carol A,Ali Ibne Karim M,Kabir Mamun,Alam Faisal
BMC Microbiology , 2012, DOI: 10.1186/1471-2180-12-151
Abstract: Background The outcome of an Entamoeba histolytica infection is variable and can result in either asymptomatic carriage, immediate or latent disease (diarrhea/dysentery/amebic liver abscess). An E. histolytica multilocus genotyping system based on tRNA gene-linked arrays has shown that genetic differences exist among parasites isolated from patients with different symptoms however, the tRNA gene-linked arrays cannot be located in the current assembly of the E. histolytica Reference genome (strain HM-1:IMSS) and are highly variable. Results To probe the population structure of E. histolytica and identify genetic markers associated with clinical outcome we identified in E. histolytica positive samples selected single nucleotide polymorphisms (SNPs) by multiplexed massive parallel sequencing. Profile SNPs were selected which, compared to the reference strain HM-1:IMSS sequence, changed an encoded amino acid at the SNP position, and were present in independent E. histolytica isolates from different geographical origins. The samples used in this study contained DNA isolated from either xenic strains of E. histolytica trophozoites established in culture or E. histolytica positive clinical specimens (stool and amebic liver abscess aspirates). A record of the SNPs present at 16 loci out of the original 21 candidate targets was obtained for 63 of the initial 84 samples (63% of asymptomatically colonized stool samples, 80% of diarrheal stool, 73% of xenic cultures and 84% of amebic liver aspirates). The sequences in all the 63 samples both passed sequence quality control metrics and also had the required greater than 8X sequence coverage for all 16 SNPs in order to confidently identify variants. Conclusions Our work is in agreement with previous findings of extensive diversity among E. histolytica isolates from the same geographic origin. In phylogenetic trees, only four of the 63 samples were able to group in two sets of two with greater than 50% confidence. Two SNPs in the cylicin-2 gene (EHI_080100/XM_001914351) were associated with disease (asymptomatic/diarrhea p = 0.0162 or dysentery/amebic liver abscess p = 0.0003). This study demonstrated that there are genetic differences between virulent and avirulent E. histolytica strains and that this approach has the potential to define genetic changes that influence infection outcomes.
Conceptual Analysis and Fieldwork in Macroeconometric Methodology: Modeling Unemployment, Inflation and Production  [PDF]
Karim Errouaki
Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.53015
Abstract:

The recent failure of commonly accepted, inductive, econometric models to provide insights into real, macroeconomic phenomenon during economic crises has provoked a debate concerning contemporary econometric methodology. Based on the foundations laid by Haavelmo, and Hollis and Nell, an assessment of Edward J. Nell’s (1998) “unifying methodological framework” (UMF) is offered. Nell’s UMF places socioeconomic institutions and interdependencies, and technological realities as basis of analysis. Using “conceptual analysis” and “fieldwork” Nell presents an alternative to generally accepted, mainstream, econometric methodology. The purpose of this paper is to look at some examples of the way, and this can help develop useful theory and improve macroeconometric model building. Applying Nell’s UMF to unemployment, inflation, and production reveals a methodological advance that promises more realistic insights into macroeconomic phenomena than is offered by contemporary, mainstream, econometric models.

Ibne Karim M. Ali ,Rashidul Haque,Abdullah Siddique,Mamun Kabir,Nicholas E. Sherman,Sean A. Gray,Gerard A. Cangelosi,William A. Petri Jr.
PLOS Neglected Tropical Diseases , 2012, DOI: 10.1371/journal.pntd.0001643
Abstract: Background The category B agent of bioterrorism, Entamoeba histolytica has a two-stage life cycle: an infective cyst stage, and an invasive trophozoite stage. Due to our inability to effectively induce encystation in vitro, our knowledge about the cyst form remains limited. This also hampers our ability to develop cyst-specific diagnostic tools. Aims Three main aims were (i) to identify E. histolytica proteins in cyst samples, (ii) to enrich our knowledge about the cyst stage, and (iii) to identify candidate proteins to develop cyst-specific diagnostic tools. Methods Cysts were purified from the stool of infected individuals using Percoll (gradient) purification. A highly sensitive LC-MS/MS mass spectrometer (Orbitrap) was used to identify cyst proteins. Results A total of 417 non-redundant E. histolytica proteins were identified including 195 proteins that were never detected in trophozoite-derived proteomes or expressed sequence tag (EST) datasets, consistent with cyst specificity. Cyst-wall specific glycoproteins Jacob, Jessie and chitinase were positively identified. Antibodies produced against Jacob identified cysts in fecal specimens and have potential utility as a diagnostic reagent. Several protein kinases, small GTPase signaling molecules, DNA repair proteins, epigenetic regulators, and surface associated proteins were also identified. Proteins we identified are likely to be among the most abundant in excreted cysts, and therefore show promise as diagnostic targets. Major Conclusions The proteome data generated here are a first for naturally-occurring E. histolytica cysts, and they provide important insights into the infectious cyst form. Additionally, numerous unique candidate proteins were identified which will aid the development of new diagnostic tools for identification of E. histolytica cysts.

Advances in Microbiology (AiM) , 2019, DOI: 10.4236/aim.2019.91001
Abstract: Pectinases, the enzymes which break down pectic substances, have a wide range of applications in food, agriculture and environmental sectors. In the present study, attempts were made to isolate highly efficient pectinase producer from the rhizosphere of a medicinal plant, Andrographis paniculata Nees, known as the “King of bitters”. The total heterotrophic bacterial count of the rhizosphere soil of A. paniculata Nees ranged from 1.53 × 109 to 2.52 × 109 cfu/g. A total of 65 bacterial colonies were randomly selected from the nutrient agar plates, purified and assessed for pectinase activity. Out of the 65 isolates, 62 (95.38%) showed varying degree of pectinase activity in plate assay using pectin as a sole source of carbon. Among the pectinase producing strains, JBST36 showed best pectinase activity which is followed by the JBST22 and JBST27. Morphological characterization, biochemical tests and 16S rRNA gene sequencing were performed to identify the three most potential strains. Based on the morphological, biochemical and molecular data, JBST22 was identified as Bacillus flexus and the other two were identified as Bacillus subtilis. Furthermore, nucleotide sequences of the 16S rRNA gene of these 3 strains were compared and a phylogenetic tree was constructed. The study reveals that there are at least 66 base differences in the 16S rRNA gene sequences of B. flexus JBST22 and the B. subtilis JBST36.
Effect of probiotics on broiler meat quality

African Journal of Biotechnology , 2009,
Abstract: The study was carried out on “Hubbard Isa Starbo” broilers to evaluate the raw meat quality of both probiotics and conventional fed broilers in pre-freezing condition and post freezing storage. 80 day old broiler chicks were divided into 4 groups of equal numbers as group A (probitotics fed group vaccinated), B (probiotics fed group nonvaccinated), C (conventional fed group vaccinated) and D (conventional fed group nonvaccinated). The groups C and D were taken as control birds and were fed with commercial ration and the groups A and B as experimental birds which were fed with commercial ration plus 2 g probiotics (Protexin Boost)/10 L drinking water up to 6th week of age. At the end of the 6 week feeding trial, the birds were slaughtered and dressed and subjected to organoleptic examination at 0, 7, 14 and 21 days of frozen storage. The increased panel scores were substantially obtained by all absorbent paper (AP) packed meat samples of probiotics fed group as compared to aluminium foil (AF) packed samples kept at frozen storage for 7, 14 and 21 days. The presence of high number of pathogenic Staphylococci and Escherichia coli encountered in meat from conventional fed broilers is alarming. The presence of these organisms in meat foods should receive particular attention, because their presence indicate public health hazard and give warning signal for the possible occurrence of food borne intoxication. The results of the study evidenced that supplementation of probiotics in broiler ration improved the meat quality both in prefreezing and postfreezing storage.

Similarity Matching Techniques For Fault Diagnosis In Automotive Infotainment Electronics
Mashud Kabir
International Journal of Computer Science Issues , 2009,
Abstract: Fault diagnosis has become a very important area of research during the last decade due to the advancement of mechanical and electrical systems in industries. The automobile is a crucial field where fault diagnosis is given a special attention. Due to the increasing complexity and newly added features in vehicles, a comprehensive study has to be performed in order to achieve an appropriate diagnosis model. A diagnosis system is capable of identifying the faults of a system by investigating the observable effects (or symptoms). The system categorizes the fault into a diagnosis class and identifies a probable cause based on the supplied fault symptoms. Fault categorization and identification are done using similarity matching techniques. The development of diagnosis classes is done by making use of previous experience, knowledge or information within an application area. The necessary information used may come from several sources of knowledge, such as from system analysis. In this paper similarity matching techniques for fault diagnosis in automotive infotainment applications are discussed.
Investigation of the Central and Peripheral Analgesic and Anti-inflammatory Activity of Kutajarishta, an Indian Ayurvedic formulation
Ashraful Kabir
International Journal of Phytopharmacy , 2012, DOI: 10.7439/ijpp.v2i5.746
Abstract: Kutajarishta (KTJ) is an Ayurvedic formulation approved by the “National formulary of Ayurvedic Medicine 2011”, of Bangladesh. It is widely available in the Bangladeshi market as an effective preparation to treat lumbago, sciatia and arthritic pain of joints. Our present studies make an attempt toward identifying probable anti-nociceptive and anti-inflammatory mechanisms of KTJ. KTJ, at three doses, (10mL/kg, 20mL/kg, and 40mL/kg) showed no involvement of the CNS in anti-nociceptive activity of KTJ. Carrageenan induced paw edema and acetic acid writhing tests both gave significant results (P ≤ 0.05), indicating possible peripheral analgesic and anti-inflammatory action. Formalin induced paw-licking test showed that KTJ had significant effect in suppressing inflammatory pain (P≤0.05) but not neurogenic pain. Hence our study shows anti-inflammatory and peripheral analgesic action for KTJ.
