Ongoing ovarian cancer screening trials are investigating the efficacy of a two-step screening strategy using currently available blood and imaging tests [CA125 and transvaginal sonography (TVS)]. Concurrently, efforts to develop new biomarkers and imaging tests seek to improve screening performance beyond its current limits. This study estimates the mortality reduction, years of life saved, an...

Seed coat crude extracts of white-coloured ITA-256, white and brown-coloured TVS-716, deep brown-coloured IT-90K and light brown-coloured Ife brown cowpea varieties were analyzed for the presence and amount of total phenol, tannin and flavonoid content. Crude extracts of the cowpea varieties were analyzed for antioxidant activity using the Thiobarbituric Acid (TBA) assay. The seed coat extracts...

Background: To present bilateral lower extremity agenesis which is a rare anomaly and to point out importance of transvaginal sonography (TVS) for the antenatal diagnosis of such anomalies during early in pregnancy. Case: A 25 year-old pregnant woman admitted to our department for first trimester nuchal translucency screening sonography. TVS revealed a 12 weeks and 2 days fetus with positive ca...

In the new era of IoT (Internet of Things), numerous gadgets and services include innovative IoT technologies that provide customers with convenience and improve their quality of life. Smart TVs are typical IoT devices that offer broadcasting services. However, they are susceptible to security intrusions via e-mail, media players, cameras, and internet connectivity. The frequency of hacking thr...

The case featured in this issue of Vikalpa discusses the journey embarked on by the top management of Lucas-TVS Limited in 1985 to make their firm a world-class manufacturing organization. The company's oldest plant at Padi, Chennai acted as a test bed for several of their initiatives. The case describes the steps that Lucas-TVS management took to implement this change process in manufacturing ...

Hydrogen production (HP) from the organic fraction of municipal solid waste (OFMSW) under thermophilic acidogenic conditions was studied. The effect of nine different organic loading rates (OLRs) (from 9 to 220 g TVS/l/d) and hydraulic retention times (HRTs) (from 10d to 0.25 d) was investigated. Normally, butyrate was the main acid product. The biogas produced was methane- and sulfide-free at ...

OBJECTIVES Tricuspid regurgitation (TR) remains a significant risk factor affecting the survival of patients with hypoplastic left heart syndrome (HLHS). We performed this study to investigate differences in the clinical course based on the timing of the development of TR and the effects of tricuspid valve surgery (TVS). METHODS One hundred and five patients of classic HLHS underwent staged o...

This paper analyzes the noise robustness of vocal tract constriction variable estimation and investigates their role for noise robust speech recognition. We implemented a simple direct inverse model using a feed-forward artificial neural network to estimate vocal tract variables (TVs) from the speech signal. Initially, we trained the model on clean synthetic speech and then test the noise robus...

BACKGROUND A 2-stage ovarian cancer screening strategy was evaluated that incorporates change of carbohydrate antigen 125 (CA125) levels over time and age to estimate risk of ovarian cancer. Women with high-risk scores were referred for transvaginal ultrasound (TVS). METHODS A single-arm, prospective study of postmenopausal women was conducted. Participants underwent an annual CA125 blood tes...

BACKGROUND Triple valve surgery (TVS) is still of choice for advanced rheumatic heart disease (RHD), which has been associated with reported poor early and late outcomes. We describe the short- and long-term results after TVS in last two decades in Mainland China. METHODS From January 1985 to January 2005, a total of 871 patients (217 men, 654 women), with mean age of 42+/-11 years, underwent...
