INTRODUCTION: Repeated blood transfusions can result in the production of alloantibodies against one or more red cell antigens, which complicates subsequent transfusions. Aims: The study was done to find incidence of various red cell alloantibodies; to determine the type of alloantibody; to identify the factors such as frequency of transfusion, splenectomy status, donor ethnicity and gender and their association with the development of antibody in repeatedly transfused patients. MATERIALS AND METHODS: This study was carried out in Dept...

Chemical and structure properties of Ethanol lignin (EL), alkali lignin (AL), milled wood lignin (MWL) and cellulase enzymatic lignin (CEL) extracted from acorn shell of Quercus variabilis Bl. were studied by GPC, TG, SEM, FT-IR, (13)C NMR, DEPT-135 NMR, 2D-HSQC and functional groups measurement. Results indicated that AL had a lower quantity of ArOH (2.19mmol/g) in four lignin samples. TG results proved the existence of a less thermally stable domain within the lignin polymer. SEM, FT-IR, (13)C NMR, DEPT-135 NMR and 2D-HSQC confirmed the lignin structural characters of the extracted samples, it was found that the relative content of β-O-4' linkage in MWL (51...

Krish Krishnamurthy, Natarajan Hari
The recently published CRAFT (complete reduction to amplitude frequency table) technique converts the raw FID data (i.e., time domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. It offers an alternate approach to decimate time-domain data, with minimal preprocessing step. It has been shown that application of CRAFT technique to process the t1 dimension of the 2D data significantly improved the detectable resolution by its ability to analyze without the use of ubiquitous apodization of extensively zero-filled data...

Vector borne diseases remain the major source of illness and death worldwide. Aedes aegypti is the primary carrier of dengue and dengue haemorrhagic fever in many developing countries in the tropical world. Because A. aegypti populations are becoming more and more resistant to conventional and non conventional insecticides, alternative strategies have to be rapidly implemented in the future for dengue vector control. The present study aimed to evaluate the larvicidal efficacy of slow-release formulations (SRFs) of bacterial insecticide Bactimos briquets blended with tow insect growth regulators (IGRs), Altosid XR - briquets and Dudim DT tablet respectively, against mosquito larvae of A...

PURPOSE OF THE STUDY: The aim of the study was to propose "the risk formula" for obstructive sleep apnea in children according to the general and local clinical parameters and findings relevant for obstructive sleep apnea (OSA) severity. The unmet need for this formula arises from the economic burden of polysomnography (device, staff, training, special sleep centers, etc) as the golden standard for the diagnostics. MATERIALS AND METHODS USED: The study was performed from January 2013 until January 2016 in the Sleep Center, Department for Neuroscience, School of Medicine of the University of Split, Department of Pediatrics, University Hospital Split, Croatia and ENT Dept...

Roccellatol, a new (2'R,3'S)-erythrityl-2,6-dihydroxy-4-methylbenzoate was isolated along with nine known compounds from the fruticose lichen, Roccella montagnei Bel. em. D.D. Awasthi. The structure of the new compound was elucidated by detailed spectroscopic analysis ((1)H, (13)C, DEPT and HRMS). The present isolation of roccellatol (10) assumes significance as the esters of p-orcellinic acid are rare in lichens. Interestingly, among the known compounds, (+)-montagnetol (9) was now isolated in very large quantity (4...
