Common Parasite With Uncommon Associations

Filaariasis a quite common in some parts of the world including India. It has been reported as an incidental finding in cytology smears. Here we report three cases where microfilariae of Wuchereria Bancrofti were detected incidentally in bone marrow smears, in two cases in special stain slides. All these patients were being investigated for other hematological disorders

Dextransucrase from the mutant of Pediococcus pentosaceus (PPm) is more stable than the wild type

A comparative study on both wild type and mutant of Pediococcus pentosaceus for dextransucrase activity, its stability, dextran synthesizing activity, antibiotic sensitivity and carbohydrate utilization was performed. The wild type P. pentosaceus had specific activity of 0.58 U/mg whereas the mutant showed that of 1.0 U/mg with 72% enhancement. The antibiogram of 27 antibiotics tested against mutant showed significant differences with 9 antibiotics when compared to wild type. In carbohydrate fermentation profile, trehalose, galactose, maltose, lactose and fructose are metabolized by both the strains, but weakly in case of mutant. Stabilization of purified dextransucrase from wild type and mutant with various stabilizers was studied at 30 and 4 °C. Both enzymes were more stable at 4 °C. Among various stabilizers such as dextran (100 kDa, 10 μg/ml), glycerol (0.5%, v/v), PEG 8000 (10 μg/ml) and Tween 80 (0.5%, v/v), Tween 80 provided maximum stabilization at 4 and 30 °C. The mutant showed better stabilization than that of the wild type at both 30 and 4 °C. The loss of activity at 30 °C after 24 h in wild type and mutant in the presence of Tween 80 was only 34 and 32%, respectively, whereas the loss of activity in control of wild type and mutant was 76 and 59%, respectively. After 15 days at 4 °C, the loss of activity in control of wild type and mutant in the presence of Tween 80 was only 15 and 8%, respectively, whereas at 30 °C, the loss of activity in control of wild type and mutant was 49 and 42% respectively. Half-life of the enzyme with Tween 80 was 28.5 and 33.5 h for wild type and mutant, respectively, at 30 °C and 52.1 and 106.6 days for wild type and mutant respectively, at 4 °C

ATRA Induced Reactive Hemophagocytosis: a Case Report

All trans-retinoic acid (ATRA) is a targeted therapy, used in Acute Promyelcytic leukemia (APL) and causes the abnormal promyelocytes to differentiate in to mature leucocytes, however their clearance in vivo is not known. ATRA has been found to be associated with hemophagocytosis, but sometimes one may find phagocytosis of differentiated cells by histiocytes without the overt manifestations of hemophagocytic syndrome. We report a case of APL showing differentiated cells being phagocytosed by marrow histiocytes while patient was getting ATRA therapy

High density linkage mapping of genomic and transcriptomic SNPs for synteny analysis and anchoring the genome sequence of chickpea

This study presents genome-wide discovery of SNPs through next generation sequencing of the genome of Cicer reticulatum. Mapping of the C. reticulatum sequenced reads onto the draft genome assembly of C. arietinum (desi chickpea) resulted in identification of 842,104 genomic SNPs which were utilized along with an additional 36,446 genic SNPs identified from transcriptome sequences of the aforementioned varieties. Two new chickpea Oligo Pool All (OPAs) each having 3,072 SNPs were designed and utilized for SNP genotyping of 129 Recombinant Inbred Lines (RILs). Using Illumina GoldenGate Technology genotyping data of 5,041 SNPs were generated and combined with the 1,673 marker data from previously published studies, to generate a high resolution linkage map. The map comprised of 6698 markers distributed on eight linkage groups spanning 1083.93 cM with an average inter-marker distance of 0.16 cM. Utility of the present map was demonstrated for improving the anchoring of the earlier reported draft genome sequence of desi chickpea by ~30% and that of kabuli chickpea by 18%. The genetic map reported in this study represents the most dense linkage map of chickpea , with the potential to facilitate efficient anchoring of the draft genome sequences of desi as well as kabuli chickpea varieties

Agriculture-Industry Interlinkages: Some Theoretical and Methodological Issues in the Indian Context

The inter-relationship between agriculture and industry has been a long debated issue in most of the developing countries. In the Indian context, the issue has acquired interest since the industrial stagnation of the mid 1960s. Over the years the Indian economy has undergone a structural change in its sectoral composition: from a primary agro-based economy during 1970s, the economy has emerged as predominant in the service sector since the 1990s. This structural change and uneven pattern of growth of agriculture, industry and services sector in the post reforms period is likely to appear substantial changes in the production and demand linkages among various sectors, and in turn, could have significant implication for the growth and development process of the economy. This has triggered a renewed interest in studying the inter-relationship between agriculture and industry. The present paper tries to address some of the theoretical and methodological issues in analyzing the agriculture-industry interlinkages in the Indian context

Increasing frailty is associated with higher prevalence and reduced recognition of delirium in older hospitalised inpatients: results of a multi-centre study

Purpose: Delirium is a neuropsychiatric disorder delineated by an acute change in cognition, attention, and consciousness. It is common, particularly in older adults, but poorly recognised. Frailty is the accumulation of deficits conferring an increased risk of adverse outcomes. We set out to determine how severity of frailty, as measured using the CFS, affected delirium rates, and recognition in hospitalised older people in the United Kingdom. Methods: Adults over 65 years were included in an observational multi-centre audit across UK hospitals, two prospective rounds, and one retrospective note review. Clinical Frailty Scale (CFS), delirium status, and 30-day outcomes were recorded. Results: The overall prevalence of delirium was 16.3% (483). Patients with delirium were more frail than patients without delirium (median CFS 6 vs 4). The risk of delirium was greater with increasing frailty [OR 2.9 (1.8–4.6) in CFS 4 vs 1–3; OR 12.4 (6.2–24.5) in CFS 8 vs 1–3]. Higher CFS was associated with reduced recognition of delirium (OR of 0.7 (0.3–1.9) in CFS 4 compared to 0.2 (0.1–0.7) in CFS 8). These risks were both independent of age and dementia. Conclusion: We have demonstrated an incremental increase in risk of delirium with increasing frailty. This has important clinical implications, suggesting that frailty may provide a more nuanced measure of vulnerability to delirium and poor outcomes. However, the most frail patients are least likely to have their delirium diagnosed and there is a significant lack of research into the underlying pathophysiology of both of these common geriatric syndromes

Sequence of a newly identified Mycobacterium tuberculosis gene encoding a protein with sequence homology to virulence-regulating proteins

Analysis of the nucleotide sequence of a gene cloned from a Mycobacterium tuberculosis H37Rv genomic library predicted a 339-amino-acid protein with an Mr of 37656. The protein exhibited significant homology with the Cfad, FapR and Rns proteins from different enterotoxigenic strains of Escherichia coli, VirF protein of Shigella and VirFy protein of Yersinia, all of which regulate virulence-associated genes

Congenital sideroblastic anemia: A report of two cases

Sideroblastic anemia, comprising of acquired and congenital forms, is a heterogeneous group of disorders characterized by the presence of ring sideroblasts in the bone marrow. Congenital sideroblastic anemia is a rare condition which is mostly X-linked, caused by mutations of delta-aminolevulinic acid synthase 2. We describe two cases of congenital sideroblastic anemia, one of them indicating an autosomal recessive inheritance, with their clinico-hematological profile. It is important to recognize this entity early in life as a significant percentage of cases respond to pyridoxine thus avoiding any long-term complications

Aplastic anaemia with microfilaria in marrow aspirate

<span>Wuchereria bancrofti is endemic in many parts of of south east asia including india. The parasite is reported previously in many aspirate cytology smears, however its rare to find this parasite in bone marrow aspirate smear and even rare is it association with aplastic anemia. We report here a case presenting with symptoms related to bone marrow failure and incidentally detected to have microfilaria of Wuchereria bancrofti. The case is reported because of this rare association.</span><br /&gt
