Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...

Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

Our aim was to identify the nociceptin receptor and its endogenous ligand, nociceptin, in human peripheral tissue. Synovial tissue was obtained from 11 patients (ASA I-III, 66-84 yr) undergoing elective total knee replacement. Synovial fluid was obtained from another 10 patients (ASA I-III, 57-81 yr). Fluid was mixed with trifluoroacetic acid and the tissue with isopentone before freezing at -7...

The sudden death of a diabetic patient (NIDDM) during Holter monitoring is described. The patient was a 64-yr-old male with an 11-yr history of diabetic nephropathy, retinopathy, autonomic nervous dysfunction, and old myocardial infarction. In spite of all these complications, he remained asymptomatic and eventually resumed his normal activities, including a daily 1-h walk, until his sudden dea...

CASE REPORT A 53-yr-old female presented with a 1-month history of cough productive of blood-flecked white sputum and right-sided chest pain. She had undergone a mastectomy 11 months previously for breast cancer. At surgery, the resection margins were free of tumour, lymph node sampling was negative, and no additional therapy was given. A chest radiograph at that time was normal. The patient’s ...

Results. During the past 5 yr, 75 consecutive patients were catheterized and usable records were available in 70. The age range was 0.1–18 yr (mean 7.1). Four children required external cardiac massage [6% (95% confident limits 1–11%)] and one of these died. Of the four, two had an arrhythmia related to the mechanical effects of catheterization, one was hypotensive during anaesthesia and the ot...

Mixed livestock grazing can offer an alternative management system for rearing dairy replacement heifers (Bos taurus). A 2-yr study was conducted during 2009 (yr 1) and 2010 (yr 2) to determine the effects of co-grazing Holstein heifers under rotational stocking with Boer × Kiko goats on animal performance, pasture DM yield, and botanical composition. Each year, 24 heifers (134 ± 6 d of age and...

Trends and periodicities in the annual rainfall of India were studied using data for 48 stations having record lengths of over 70 yr. Increasing or decreasing rainfall tendencies were found over large continuous areas in India. These trends, however, are not significant over all the stations in the areas but only at a few places distributed a t random. Wherever a trend is significant, i t has p...

We investigated the prevalence of pertussis in Korean adolescents and adults with persistent cough. Study population was adolescents (aged 11-20 yr) and adults (≥ 21 yr old) who showed persistent cough of 1-8 weeks' duration. Pertussis was diagnosed by culture, polymerase chain reaction (PCR), and serology. A total of 310 subjects participated in this study, and 76 cases (24.5%) met the criteri...
