WHO 75 gram OGTT-A single step procedure for screening and diagnosis of gestational diabetes mellitus

Background: Indian women have an eleven fold increased risk of developing glucose intolerance during pregnancy compared to Caucasian women .Universal screening for GDM is essential in India. This study was undertaken to find out a single step procedure which serves both as a screening and a diagnostic tool. Methods: This study was carried out in a tertiary care teaching institute in Karnataka. 839 pregnant women with gestational age between 24-28 weeks were subjected to 50 gram OGCT and venous blood was drawn after 1 hour. These patients were requested to come after 72 hours on empty stomach for WHO-75 gram OGTT. Fasting and 2 hour blood samples after 75 gram of glucose were drawn.Results: Amongst the 839 pregnant women who underwent 50 gram OGCT, 136 (16.2%) women had one hour plasma glucose >140 mg/dl. Subsequent 75 gram OGTT revealed that only 43 (31.62%) of screen positive patients were diabetic.93 women who tested positive by 50 gram OGCT were false positive cases (10.58%). Prevalence of GDM in study population was 6.3 % (53/839). Screening OGCT missed 10 (15.87%) of gestational diabetes mellitus cases which were picked up by 75 gram WHO OGTT only.Conclusions: The diagnosis of Gestational Diabetes Mellitus by OGTT based on initial OGCT screening leaves 15.87% undiagnosed. The two step method of screening OGCT and diagnosing GDM with subsequent OGTT is tedious and not economical. Instead a single step WHO 75 gram fasting OGTT with 2 hour PPG ≥ 140 mg/dl is simple and precise

A clinical study of trends of ectopic pregnancy and its management in a tertiary care hospital

Background: Ectopic gestation is a gynaecological emergency which culminates in pregnancy loss and causes significant maternal morbidity, mortality besides jeopardizing future conception. The study discusses the incidence, risk factors, symptomatology and management of ectopic pregnancy in a tertiary care teaching hospital.Methods: This was a prospective study of 45 cases of ectopic pregnancies at a tertiary care teaching hospital from January 2012 to December 2013. Information was collected in a structured proforma, tabulated and descriptive analysis was carried out.Results: The incidence of ectopic pregnancy was 1.17%. Majority of the patients (80%) belonged to 20-30 yrs age group. Second gravidas predominated (42.2%). Fallopian tube was the most common site (95.5%). Rudimentary horn ectopic accounted for 4.65%. Previous abdominopelvic surgery (31.1%), IUCD usage (22.2%), PID (20%), abortions (20%), tubectomy (15.5%) were the principal risk factors. 42% of the patients had no risk factor. The triad of amenorrhea, bleeding per vaginum and abdominal pain was seen in 51.1% of cases. Ultrasound, UPT, β-hCG estimation were the diagnostic tools. Ruptured ectopic pregnancy accounted for 64.4%. Nearly 95.5% of patients underwent surgery; salpingectomy (76%). Methotrexate was successful in 4.44%. There was no maternal mortality.Conclusions: Mostly diagnosis, prompt surgical or medical management is cornerstone of treatment. Primary prevention such as improved access to family planning services, sex education, treatment of STI, PID, surgical asepsis  and haemostasis, implementing legislation for dispensing MTP drugs ameliorate risk factors and hence reduce ectopic pregnancy

Cytological and molecular evidence for Wolbachia infection in uzi flies of Exorista species

The cytoplasmically inherited bacterial symbiont, Wolbachia is well known for inducing a variety of reproductive abnormalities in the diverse arthropod hosts it infects. Wolbachia has been implicated in causing cytoplasmic incompatibility, parthenogenesis, and the feminization of genetic males in different hosts. In the present investigation, electron microscopy and PCR technology was applied on uzi flies of Exorista species (Diptera: Tachinidae), serious pests of silkworm Bombyx mori L. TEM examination of uzi flies of Exorista species showed Wolbachia in the reproductive tissues. Details of the ultrastructure of Wolbachia are described. The application of PCR technique revealed that the Wolbachia is present in uzi fly populations of Exorista species collected from different localities. Thereby it creates a lot of scope for future research on the management of uzi flies by means of Wolbachia

A preliminary assessment of machinability of titanium alloy Ti 6Al 4V during thin wall machining using trochoidal milling

Titanium alloys are of great demand in the aerospace and biomedical industries. Most the titanium products are either cast or sintered to required shape and finish machined to get the appropriate surface texture to meet the design requirements. Ti-6Al-4V is often referred as work horse among the titanium alloys due to its heavy use in the aerospace industry. This paper is an attempt to investigate and improve the machining performance of Ti-6Al-4V. Thin wall machining is an advance machining technique especially used in machining turbine blades which can be done both in a conventional way and using a special technique known as trochoidal milling. The experimental design consists of conducting trials using combination of cutting parameters such as cutting speed (vc), 90 and 120 m/min; feed/tooth (fz) of 0.25 and 0.35 mm/min; step over (ae) 0.3 and 0.2; at constant depth of cut (ap) 20mm and using coolant. A preliminary assessment of machinability of Ti-6Al-4V during thin wall machining using trochoidal milling is done. A correlation established using cutting force, surface texture and dimensional accuracy

Molecular docking studies of benzimidazopyrimidine and coumarin substituted benzimidazopyrimidine derivatives: As potential human Aurora A kinase inhibitors.

Protein kinases are important drug targets in human cancers, inflammation and metabolic diseases. Docking studies was performed for all the benzimidazopyrimidine and coumarin substituted benzimidazopyridimine derivatives with human Aurora A kinase target (3FDN) employing flexible ligand docking approach by using AutoDock 4.2. All the compounds were found to have minimum binding energy ranging from -6.26 to -9.29 kJ/mol. Among the molecules tested for docking study, 10-(6-Bromo-2-oxo- 2H-chromen-4-ylmethyl)-2-isopropyl-10H-benzo[4,5]imidazo[1,2-a]pyrimidin-4-one (2k) showed minimum binding energy (-9.29 kJ/mol) with ligand efficiency of -0.31. All the ligands were docked deeply within the binding pocket region of 3FDN showing hydrogen bonds with Ala 213 and Asn 261. The docking study results showed that these derivatives are excellent inhibitor of human Aurora A kinase target; and also all these docked compounds have good inhibition constant, vdW + Hbond + desolv energy with best RMSD value

Vibrational spectroscopy investigation using M06-2X and B3LYP methods analysis on the structure of 2-Trifluoromethyl-10H-benzo[4,5]-imidazo[1,2-a]pyrimidin-4-one

In this study, the experimental and theoretical vibrational frequencies of a newly synthesized bioactive agent namely, 2-Trifluoromethyl-10H-benzo[4,5]-imidazo[1,2-a]pyrimidin-4-one (TIP) have been investigated. The experimental FT-IR (4000-400 cm(-1)) and Laser-Raman spectra (4000-100 cm(-1)) of the molecule in solid phase have been recorded. The theoretical vibrational frequencies and the optimized geometric parameters (bond lengths and bond angles) have been calculated using density functional theory (DFT/B3LYP: Becke, 3-parameter, Lee-Yang-Parr) and M06-2X (the highly parametrized, empirical exchange correlation function) quantum chemical methods with 6-311++G(d,p) basis set by Gaussian 09W software, for the first time. The assignments of the vibrational frequencies have been done by potential energy distribution (PED) analysis using VEDA 4 software. The theoretical optimized geometric parameters and vibrational frequencies have been found to be in good agreement with the corresponding experimental data and results in the literature. In addition, the highest occupied molecular orbital (HOMO) energy, the lowest unoccupied molecular orbital (LUMO) energy and the other related molecular energy values of the compound have been investigated using the same theoretical calculations.
