ABSTRACT The Karnal bunt pathogen, Tilletia indica, is heterothallic and depends on encounters on wheat spikes between airborne secondary sporidia of different mating types for successful infection and reproduction. This life history characteristic results in reduced reproductive success for lower population densities. Such destabilizing density dependence at low population levels has been desc...

To strengthen the depth of lightweight rowing talent, we sought to identify experienced heavyweight rowers who possessed physique traits that predisposed them to excellence as a lightweight. Identified athletes (n = 3) were monitored over 16 wk. Variables measured included performance, anthropometric indices, and selected biochemical and metabolic parameters. All athletes decreased their body m...

Background Multiple studies document specific personality traits, relatively homogeneous in the structural aspect. We attempt to extrapolate a purely psychological examination approach, applying the clinical conceptualizations of H. Akiskal. This study aims to asses the existence of statistically significant differences between the TEMPSA scale ratings of subjects serving a prison sentence and ...

Animal movement is a fundamental eco-evolutionary process yet the behaviour of juvenile animals is largely unknown for many species, especially for soaring seabirds which can range widely over the oceans at low cost. We present an unprecedented dataset of 98 juvenile albatrosses and petrels (nine species), tracked for the first three months after independence. There was a startling diversity wi...

Individuals with cytological atypia in sputum may be at increased risk for lung cancer. We conducted a longitudinal analysis of the association between lung cancer incidence and cytological atypia in sputum samples collected prospectively from an ongoing cohort of adults at high risk for lung cancer. Cohort members had a smoking history of > or = 30 pack-years and chronic obstructive pulmonary ...

Background & Objectives: Tumor diathesis (TD) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. It is found in the background of smears of invasive carcinoma but not in all cases. The aim of present study was to determine the prevalence of TD in cervicovaginal smears from patients with uterine cervix carcinoma. Methods: Cytological smears and histological ...

A 60-year-old female developed a right parotid swelling six months after surgery for intra-oral squamous cell carcinoma. Fine needle aspiration (FNA) cytological smears showed dissociated large and small pleomorphic tumour cells with abundant mitoses and oncocytic features. A cytological diagnosis of parotid acinic cell carcinoma (ACC) was made. Histological study of the subtotal parotidectomy ...

The aim of the present study was to investigate the diagnostic efficacy of telomerase activity for discrimination of malignant and benign pleural effusions. Pleural effusions were collected from 109 consecutive patients in whom the diagnosis was confirmed with cytological and/or histological examinations. Cytological samples were classified as malignant (n=63) and benign (n=46). Telomerase acti...
