Nucleosomes in pancreatic cancer patients during radiochemotherapy [PDF]
, 2005 Nucleosomes appear spontaneously in elevated concentrations in the serum of patients with malignant diseases as well as during chemo- and radiotherapy. We analyzed whether their kinetics show typical characteristics during radiochemotherapy and enable an

Estimation of median lethal dose of Fenpropathrin in Wistar rat.
Journal of Ecophysiology and Occupational Health, 2021 Background: Fenpropathrin, a synthetic pyrethroid (Type I/II) is commonly used as an insecticide in homes and in agriculture. The present study was planned to determine the median lethal dose (LD 50 ) of Fenpropathrin in adult Wistar rats, both male and female.

Is birthweight associated with total and aggressive/lethal prostate cancer risks? A systematic review and meta-analysis [PDF]
, 2016 BACKGROUND: It has been hypothesised that intrauterine exposures are important for subsequent prostate cancer risk. Prior epidemiological studies have used birthweight as a proxy of cumulative intrauterine exposures to test this hypothesis, but results ...

Epileptic high-frequency network activity in a model of non-lesional temporal lobe epilepsy [PDF]
, 2010 High-frequency cortical activity, particularly in the 250–600 Hz (fast ripple) band, has been implicated in playing a crucial role in epileptogenesis and seizure generation. Fast ripples are highly specific for the seizure initiation zone.

Median Lethal Dose (Ld50) Of Electric Current [PDF]
Current Trends in Biomedical Engineering & Biosciences, 2019 Electric current constitutes potential hazards across the globe. In view of this, literatures were assessed for determination of lethal dose of electric current that would kill 50% of human (LD50), using cardiorespiratory pathological signs. The low LD50 value of electric current (36.5±21.3mA) and voltage (11.0±6.4 V) respectively, suggest very serious
