X-parameters are developed as a superset of S-parameters and they are suitable for modeling systems having only radio-frequency (RF) and DC ports. For a polar power amplifier (PA), the envelope of the input modulated signal is applied at the envelope port, which is neither an RF nor a DC port. In this case, X-parameter may fail to characterize the behavior of the envelope path and consequently ...

BACKGROUND The use of laboratory intervals based on younger and healthier populations is of questionable validity in older populations. The aim of this study was to examine haematological and biochemical profiles in a sample of community-dwelling older people and to study the impact of age, disease, disability and medications. METHODS Basic haematological and biochemical values were obtained ...

The haematological and serum biochemical responses of broilers fed indomie waste-based diets (IWBD) were investigated using one hundred and ninety (180) day-old broiler chicks of Anak strain. The chicks were randomly allotted to the different dietary treatments having graded levels of the IWBD in a Completely Randomized Design (CRD). Each treatment contained 3 replicates and each replicate had ...

Metronidazole is an antibiotic which is widely used in the treatment of parasitic diseases. Several studies have reported its tumorigenic, mutagenic and antimicrobial effects, but there is a dearth of information on its effect on blood chemistry. This study was designed to investigate its effect on haematological parameters in male albino rats. Treatment of rats for 25 days with 400 mg/kg BW of...

Scorpion stings are common in Iran, particularly in the southern and southwest regions of the country, and they pose a serious health problem. Hemiscorpius lepturus is the most venomous scorpion in the region. The present study was conducted to investigate the in vivo effects of scorpion venom in experimental mice. Haematological parameters (white and red blood cells numbers and haematocrit lev...

Long-term exposure to low doses of ionizing radiation may affect cells and tissues and result in various adverse health effects. The purpose of this study was to investigate whether chromosome aberrations and haematological alterations could be used as biomarkers of possible radiation injury in workers exposed to ionizing radiation. Groups totalling 323 medical professionals handling X-ray equi...

OBJECTIVE An experiment was conducted to study the blood haematology, muscle pH, and serum cortisol changes in pigs with different levels of drip loss. METHODS Two groups (low and high) of 20 animals were selected from 100 pigs based on drip loss. All [Duroc× (Large White×Landrace)] pigs were slaughtered according to standard slaughtering procedures. At exsanguinations, blood samples were tak...

A study on the influence of gastrointestinal trichostrongyles on ram fertility was performed. Two groups of semen donor rams (Sarda breed) were utilized; one was experimentally infected with Haemonchus contortus, Trichostrongylus colubriformis and Teladorsagia circumcincta and the other was used as a control group. In all animals, coprological, haematological and reproductive parameters were st...
