Comparative Micro-Morphology and Reproductive Studies in Three Mulberry Varieties (Moraceae)

Three evolved mulberry verities, viz., RFS175, S41 and Morus cathyana were selected for the micro morphology and reproductive studies. Height, internodal distance, colour of leaves, stem, stomatal frequency, length and number of inflorescence and pollen fertility were studied for these three varieties. Mulberry varieties studied exhibited considerable variations in height, internodal distance, leaf texture, stomatal frequency and pollen stain ability. Stomatal frequency and pollen stain ability was higher in diploids when compared to triploid and tetraploid variety. Tetraploid showed reduction in height, number of branches and internodal distance followed by diploid and triploid varieties

Highly sensitive N-(1-naphthyl)ethylene diamine method for the spectrophotometric determination of trace amounts of nitrite in various water samples

A rapid, simple, sensitive and selective spectrophotometric determination of trace nitrite is described. The method is based on a diazotization-coupling reaction between dapsone and N-(1-naphthyl)ethylenediamine dihydrochloride (NEDA) in a hydrochloric acid medium. The molar absorptivity and Sandell's sensitivity were found to be 7.2x10(4) 1 mol(-1) cm(-1) and 0.00063 mug ml(-1), respectively. The calibration graph is linear for 0.002-0.6 mug ml(-1) of nitrite. The interference effects of various cations and anions were also studied and reported. This method has been found to be applicable to the determination of nitrite in various water samples

A Study Of The Role Indian Accountants In Managerial Decision Making

This paper studies the extent of participation of accountants in the managerial decision making process in India.  In general, accountants had the most influence over decisions relating to management information systems (MIS), financing, production, resource allocation, new product introduction and discontinuance of old products. They had the least influence over decisions relating to marketing and personnel.  For some of the decision variables studied, professional experience and size of firm were significant factors affecting responses.  Factor and cluster analyses identified two distinct factors/clusters: a participation factor/cluster consisting of eight of the nine participatory variables studied, and a MIS-budgeting factor/cluster consisting of usefulness of the budget, involvement in MIS decisions, and the level of top management support

Second order cone programming approaches for handling missing and uncertain data

We propose a novel second order cone programming formulation for designing robust classifiers which can handle uncertainty in observations. Similar formulations are also derived for designing regression functions which are robust to uncertainties in the regression setting. The proposed formulations are independent of the underlying distribution, requiring only the existence of second order moments. These formulations are then specialized to the case of missing values in observations for both classification and regression problems. Experiments show that the proposed formulations outperform imputation

Morphological, Anatomical and Reproductive Parameters in few Varieties of Mulberry (Morus spp.)

Regarding anatomical, morphological and reproductive studies of four mulberry verities namely, Channapatna local, Thailand, Morus cathyana HEMSLEY and Morus multicaulis were selected. Height, internodal distance, colour of leaves, stem, stomatal frequency, length and number of inflorescence and pollen fertility were studied for these four varieties. Mulberry varieties studied exhibited considerable variations in height, internodal distance, leaf texture, stomatal frequency, length, breadth and pollen stain ability. Height, stomatal frequency and pollen stain ability was higher in diploid and uneuploid when compared to triploid and tetraploid varieties. Tetraploid and triploid varieties showed increased stomatal size, reduction in height, number of branches and internodal distance followed by diploid and triploid varietie

Management of the hospitalized transplant patient.

Significant hyperglycemia is commonly observed immediately after solid organ and bone marrow transplant as well as with subsequent hospitalizations. Surgery and procedures are well known to cause pain and stress leading to secretion of cytokines and other hormones known to aggravate insulin action. Immunosuppression required for transplant and preexisting risk are also major factors. Glucose control improves outcomes for all hospitalized patients, including transplant patients, but is often more challenging to achieve because of frequent and sometimes unpredictable changes in immunosuppression doses, renal function, and nutrition. As a result, risk of hypoglycemia can be greater in this patient group when trying to achieve glucose control goals for hospitalized patients. Key to successful management of hyperglycemia is regular communication between the members of the care team as well as anticipating and rapidly implementing a new treatment paradigm in response to changes in immunosuppression, nutrition, renal function, or evidence of changing insulin resistance

Efficacy and safety of sitagliptin for the treatment of new-onset diabetes after renal transplantation.

New-onset diabetes after transplantation (NODAT) is a common comorbidity after renal transplantation. Though metformin is the first-line agent for the treatment of type 2 diabetes, in renal transplant recipients, metformin is frequently avoided due to concerns about renal dysfunction and risk for lactic acidosis. Therefore, alternative first-line agents for the treatment of NODAT in renal transplant recipients are needed. Sitagliptin, a dipeptidyl-peptidase-4 (DPP-4) inhibitor, has a low incidence of hypoglycemia, is weight neutral, and, in a small study, did not affect immunosuppressant levels. However, long-term sitagliptin use for the treatment of NODAT in kidney transplant recipients has not been studied. We retrospectively analyzed renal transplant recipients diagnosed with NODAT and treated with sitagliptin to assess safety and efficacy. Twenty-two patients were started on sitagliptin alone. After 12 months of followup, 19/22 patients remained on sitagliptin alone with a significant improvement in hemoglobin A1c. Renal function and immunosuppressant levels remained stable. Analysis of long-term followup (32.5 ± 17.8 months) revealed that 17/22 patients remained on sitagliptin (mean hemoglobin A1c \u3c 7%) with 9/17 patients remaining on sitagliptin alone. Transplant-specific adverse events were rare. Sitagliptin appears safe and efficacious for the treatment of NODAT in kidney transplant recipients
