Avian brood parasites reduce host fitness through the addition of parasitic eggs and the removal of host eggs. Both parasitic egg-addition and host egg-removal may be important sources of selection on host behaviour, creating fitness trade-offs with selection imposed by nest predation. However, the relative costs hosts suffer from egg-addition and host egg-removal and the responses to these cos...
BACKGROUND Dengue fever is caused by mosquito-borne arboviral infection that has become a public health concern globally. Recently, an alarming rise of dengue has also been seen in India. Hence the study was undertaken to know profile of clinical manifestations and laboratory findings during the evolution of dengue fever. METHODS In this study, retrospective data analysis was done in 216 sero...
Acute corticosterone secretion helps individuals survive perturbation, particularly when faced with unpredictable conditions. However, elevated corticosterone is often incompatible with reproduction. Male Yellow Warblers (Dendroica petechia) breeding at high latitude avoid this conflict by exhibiting a reduced adrenocortical response while provisioning nestlings. To determine if this reduction ...
The faunas associated with oceanic islands provide exceptional examples with which to examine the dispersal abilities of different taxa and test the relative contribution of selective and neutral processes in evolution. We examine the patterns of recent differentiation and the relative roles of gene flow and selection in genetic and morphological variation in the yellow warbler (Dendroica petec...
With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples th...
Giant chorioangioma is a placental tumor associated with gestational complications such as preeclampsia, polyhydramnios and hemorrhage. In addition, this tumor might lead to the incidence of non-immune fetal hydrops, heart failure, anemia, thrombocytopenia, weight loss and death among neonates. In this case report, the clinical image of a term newborn (weighing 2800 g) with one-minute Apgar sco...
Haemosporidian parasites in the genus Plasmodium were recently detected through molecular screening in the Galapagos Penguin (Spheniscus mendiculus). We summarized results of an archipelago-wide screen of 3726 endemic birds representing 22 species for Plasmodium spp. through a combination of molecular and microscopy techniques. Three additional Plasmodium lineages were present in Galapagos. Lin...
mediastinal neoplasms are uncommon tumors that can occur at any age but are most common through the fifth decades of life. a wide variety of systemic disorders are associated with 71% of thymomas. the symptoms of these as sociated disorders often lead to the original discovery of the mediastinal tumor. a 35-year-old female with petechia and purpura was admitted to sina hospital of the city of h...
Background & Aims : Henoch–Schönlein purpura (HSP) is an autoinflammatory disease and systemic small vessel vasculitis that more frequently occurs in children. It is characterized by skin lesion such as Petechia and purpura, gasterointestinal involvement including abdominal pain and gastrointestinal bleeding and arthiritis. Studies have shown that HSP could be due to different infections an...
Introduction: Crimean-Congo hemorrhagic fever (CCHF) is a viral hemorrhagic fever of the Nairovirus group. Although primarily a zoonosis, sporadic cases and outbreaks of CCHF affecting human do occur. The disease is endemic in many countries in Africa, Europe and Asia. Onset of symptoms is sudden, with fever, myalgia, dizziness, neck pain and stiffness, backache, headache, sore eyes and photo...
