Molecular analysis of chickpea using DNA technology has been carried out to identify the diverse genetic base of the cultivars for selected preferential introductions as efficient edible elements. A few of these genetic stocks have been documented here to tap their genetic diversity. The status shows that the level of polymorphism in this species is low. Using PCR based markers, marker assisted selection of polymorphy is one of the established techniques. Here, this procedure has been employed to expedite gene/QTL pyramiding in the chickpea. The study presented here includes analysis of 12 germplasms of chickpea. Standard CTAB method has been performed, with certain modifications, to get better intensity and resolution of DNA bands. Extracted DNA, amplified with 41 RAPD and 21 ISSR primers are thereby tested to determine genetic diversity. The presentation discusses the results of chickpea germplasm diversity on the basis of these observations.展开更多

Titrating catecholamine infusion to achieve higher MAP has been demonstrated to improve tissue oxygenation, microcirculation, renal function and overall outcome of the patient in some studies and literature on actual hemodynamic goals is scarce. AIM: To study the influence of two MAP on tissue oxygenation and perfusion parameters in patients of septic shock on norepinephrine infusion. SUBJECT AND MATERIALS: Forty adult patients with the diagnosis of septic shock were enrolled. In all patients norepinephrine was titrated to first stabilize the MAP at 65 ± 5 mmHg (Set I), followed by MAP of 85 ± 5 mmHg (Set II). Heart rate (HR), Central venous oxygen saturation (SCVO2), Transcutaneous partial pressure of oxygen (PtcO2) by TCM 400/TINA (using miniature Clark electrode), Arterial partial pressure of oxygen(PaO2), PtO2/PaO2 ratio, Urine output and Serum Base deficit were recorded in each Set after 2 hrs of stabilization. RESULTS: There was a significant increase in transcutaneous partial pressure of oxygen PtcO2 (p tO2/PaO2 (p < 0.0001), ScvO2 (p < 0.0001), urine output (p < 0.006) on increasing the MAP from 65mmHg to 85mmHg. Serum base deficit also improved (p < 0.0001). CONCLUSION: Higher MAP with norepinephrine is associated with better perfusion, oxygenation parameters in patients with established septic shock. These findings suggest that there is improvement in tissue oxygenation parameters using escalating doses of norepinephrine to achieve higher MAP without inherent adverse展开更多
