Abstract
Abstract
Introduction
Oral glucocorticoids are efficacious agents for treating respiratory diseases, with high risk to induce metabolic diseases including diabetes and hypertension
Purpose
To analyse the hypertensive patient population from the rural setting on ongoing glucocorticoid treatment and diagnosed as diabetic due to the extensive chronic methylprednisolone equivalent glucocorticoid dose of more than 4 mg/day for at least 3 months for treatment of respiratory ailments due to occupational hazard
Methods
We diagnosed the identified and analysed a subset of patients from the Redi iron ore miners (n=25,500), who were newly diagnosed diabetics (n=1100) and with associated systemic hypertension (systolic BP >140 mmHg, diastolic BP > than 90 mmHg). Patients diagnosed as Oral Glucocorticoid Induced Diabetes Mellitus (GIDM) and hypertensives (n=847; 572 males and 275 females) were characterised on metabolic parameters. t-test was utilised for statistical analysis
Results
We observed a high incidence of GIDM (4.31%) with a high rate of hypertension (77%, 847/1100). Mean SBP was 150 mmHg (SD ± 9.9, 95% CI 147–152), mean DBP was 90 mmHg (SD ± 8.9, 95% CI 88–92). BMI in GIDM with hypertension (GIDM-H) group was similar to GIDM group (26 kg/m2) (Table), with relatively older age in GIDM–H (53 vs 51 years). The glycemic parameters were relatively more deranged in GIDM-H group. There was significant correlation for a high propensity of relatively younger <50 years (n=506) and near normal weight people with BMI <26 kg/m2 (n=594) to develop GIDM (p=0.006)
Metabolic Parameters GIDM Vs GIDM-H Mean ±SD, min, max, 95% CI GIDM (n=1100) GIDM with Hypertension (n=847) Age (yrs) 51 (SD ±14, 95% CI 48–54) 53 (SD ±13, 95% CI 50–56) HbA1c (%) 7.1 (SD ±0.62, 95% CI 7–7.3), 7.2 (SD ±0.60, 95% CI 7.1–7.3) BMI (kg/m2) 26 (SD ±3.6, 95% CI 25–27) 26 (SD ±3.4, 95% CI 25–27) Fasting Plasma Glucose (mg/dl) 146 (SD ±49, 95% CI 136–155) 149 (SD ±48, 95% CI 138–160) Post Prandial Glucose (mg/dl) 207 (SD ±74, 95% CI 192 - 221) 212 (SD ±74, 95% CI 195–228)
Conclusions
The high rates of hypertension in patients with GIDM is an alarmingly problem which has pronounced harmful comorbid implications, especially in younger, economically productive population in limited resource setting. The health care professionals need to be educated to limit use of glucocorticoids to inhalational therapy with minimal systemic effects. Specific pathophysiological approach to address the steroid induced insulin resistance, strategies to reduce cardiovascular risk and damage, makes treatment of hypertension and GIDM difficult, which calls for action to limit the mining activities and mitigate risk of chronic complications

Abstract
We have developed a large-scale, expression-based gene trap strategy to perform genome-wide functional analysis of the murine hematopoietic and vascular systems. Using two different gene trap vectors, we have isolated embryonic stem (ES) cell clones containing lacZ reporter gene insertions in genes expressed in blood island and vascular cells, muscle, stromal cells, and unknown cell types. Of 79 clones demonstrating specific expression patterns, 49% and 16% were preferentially expressed in blood islands and/or the vasculature, respectively. The majority of ES clones that expressed lacZ in blood islands also expressed lacZ upon differentiation into hematopoietic cells on OP9 stromal layers. Importantly, the in vivo expression of the lacZ fusion products accurately recapitulated the observed in vitro expression patterns. Expression and sequence analysis of representative clones suggest that this approach will be useful for identifying and mutating novel genes expressed in the developing hematopoietic and vascular systems.

Abstract
Macrophages are phagocytic hematopoietic cells involved in several immune processes, but they are also present early in mammalian development and may participate in embryonic tissue remodeling. We have isolated and characterized a cell line, Py-YSA, from the mouse yolk sac. Py-YSA cells have several functional properties of macrophages, including uptake of acetylated low density lipoprotein and phagocytic capability. They express the murine macrophage markers F4/80 and Mac-1, and they express RNA for the c-fms receptor. Their expansion in culture requires fibroblast conditioned medium or exogenous monocyte-colony stimulating factor. Murine ES (embryonic stem) cell cultures that undergo in vitro differentiation recapitulate yolk sac development, and during this process cells arise that express both Mac-1 and F4/80 and morphologically resemble the Py-YSA cells. The kinetics and distribution pattern of the Mac-1+ cells during a time course of ES cell differentiation suggest that they originate in the blood islands, and that they subsequently leave the blood islands and disperse to tissue sites. Both F4/80 and Mac-1 are first expressed in primary cultures from day 9.5 yolk sacs. The Py-YSA cultured cells thus resemble embryonic tissue macrophages by several criteria, and they share a marker profile with a cell type found in yolk sacs and differentiating ES cells. Py-YSA cells will be a useful reagent for further understanding the role of embryonic tissue macrophages in development.

Abstract
The scalloped (sd) locus of Drosophila melanogaster encodes a protein with a novel DNA binding domain bearing a high degree of similarity to the human transcription factor TEF-1 (Campbell et al., 1992). We demonstrate that sd mutants show defects in response to a number of taste stimuli. Higher stimulus concentrations are required to elicit behavioral responses from mutant larvae and adult flies. The electrophysiological responses of the peripheral taste neurons in the labellum were found to be normal, suggesting that an inability to detect stimuli is not the cause of the mutant phenotype. The range of mutant responses of sd alleles to salt and sugar stimuli define a functional requirement for the gene in the nervous system and provide an assay for the genetic and molecular analysis of this role.

Abstract
The scalloped (sd) gene of Drosophila melanogaster was initially characterized by mutants affecting structures on the wing of the adult fly. The sequence of a cDNA clone of the gene reveals a predicted protein sequence homologous to that of a human transcriptional enhancer factor, TEF-1 (68% identity). The homology includes a sequence motif, the TEA domain, that was shown previously to be a DNA-binding domain of TEF-1. An sd enhancer trap strain expresses the reporter gene in a subset of neuroblasts in the central nervous system and in the peripheral sense organs of the embryo. The reporter gene is later expressed in specific regions of the imaginal discs, including regions of the wing disc destined to become structures defective in viable sd mutants. Later still, expression in the adult brain is restricted to subsets of cells, some in regions involved in the processing of gustatory information. These observations indicate that the sd gene encodes a transcription factor that functions in the regulation of cell-specific gene expression during Drosophila development, particularly in the differentiation of the nervous system.
