Measuring stress in animals is an important component of many research studies, and it has traditionally been performed via sampling levels of corticosterone in plasma. A secondary, ‘‘hematological’’ approach used most commonly by researchers of birds, mammals, and other taxa involves evaluating leukocyte profiles from blood smears. Such research has shown that leukocytes have a characteristic ...

BACKGROUND Malaria is considered as the main differential diagnosis of acute febrile illness in the tropics, and alteration of various hematological parameters has been observed in patients with malaria. AIM To ascertain if certain hematological parameters increase the probability of malaria in patients with acute febrile illnesses. SETTINGS AND DESIGN Hospital based, prospective cohort stu...

Hematological parameter changes are the most common complications in malaria. We aimed to determine the hematological parameters and hemozoin-containing leukocytes and their association with disease severity in malaria infected children aged between 1 and 15 years. A facility-based cross-sectional study was conducted at Pawe General Hospital from July 31 to December 30, 2014. Demographic and cl...

BACKGROUND There is need for locally-derived age-specific clinical laboratory reference ranges of healthy Africans in sub-Saharan Africa. Reference values from North American and European populations are being used for African subjects despite previous studies showing significant differences. Our aim was to establish clinical laboratory reference values for African adolescents and young adults ...

Para-clinical tests and gross lesion play important roles in identifying parasite disease as all organs ofpigeonsuch as skin, eyes, kidneys, liver and digestive tube can be affected by the parasites. Consequently, there is a possibility to use the feces of pigeon in order to observe parasite ovum and larva to identify the disease. This research was conducted from May to September 2011 and the n...

This experiment was conducted to evaluate the efficacy of different levels of Echinacea (Echinacea purpurea) methanol extract on the growth performances (final weight (FW), daily growth ratio (DGR), feed conversion rate (FCR), voluntary feed intake (VFI) and protein efficiency ratio (PER) and some of hematological parameters (hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) and white blo...

We study the dynamics of a model of white-blood-cell (WBC) production. The model consists of two compartmental differential equations with two discrete delays. We show that from normal to pathological parameter values, the system undergoes supercritical Hopf bifurcations and saddle-node bifurcations of limit cycles. We characterize the steady states of the system and perform a bifurcation analy...

Diagnosis of infections in cancer patients is usually problematic since differentiating between infection and fever of unknown origin is often a considerable clinical challenge. In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detectin...
