in desert reclamation strainer plants can be used for improvement and decrease pollution of soil and water. this technology can be used to remove both inorganic and organic contaminants in soil. in this study, one year old acacia victoriae seedlings were exposed to pb (no3)2 in 5 different concentrations; 0, 50, 250, 500 and 1000 mg pb l-1 for 45 days in two growing seasons. subsequently, the h...

BACKGROUND Depressive symptoms display heterogeneous trajectories across adolescence and early adulthood. Identifying risk and protective factors for distinct trajectory groups, and their respective outcomes, may provide insight into the etiological underpinnings of different symptom courses and inform the targets and timing of intervention. METHODS A school-based sample of 719 adolescents co...

BACKGROUND Schizophrenia is a heterogeneous disorder in terms of patient response to antipsychotic treatment. Understanding the heterogeneity of treatment response may help to guide treatment decisions. This study was undertaken to capture inherent patterns of response to antipsychotic treatment in patients with schizophrenia, characterize the subgroups of patients with similar courses of respo...

BACKGROUND Schedule-based and in-season factors (e.g., competition type) have been shown to be associated with symptom reporting patterns and injury severity in sport-related concussion (SRC). To determine if acute neurocognitive and symptom presentation following SRC differ by time point within a high school football season. METHODS Multicenter ambispective cohort of high school football pla...

Symptom assessment in early psychosis research typically relies on scales validated in chronic schizophrenia samples. Our goal was to inform investigators who are selecting symptom scales for early psychosis research. We described measure characteristics, baseline scores, and scale inter-relationships in clinical-high-risk (CHR) and recent-onset psychotic disorder (RO) samples using the Positiv...

p. vivax malaria with suspected long incubation have been frequently observed mostly in the northwest part of iran in the course of malaria control and malaria eradication operations. a sero-epidemiological study of such cases which present the first symptom in early spring, before anopheles activities season, was carried out in 92 selected villages with a population of 38,726 in two near areas...

Neurobiological markers of stress symptom progression for healthy survivors from a disaster (e.g., an earthquake) would greatly help with early intervention to prevent the development of stress-related disorders. However, the relationship between the neurobiological alterations and the symptom progression over time is unclear. Here, we examined 44 healthy survivors of the Wenchuan earthquake in...

OBJECTIVES The high percentage of failed clinical trials for anti-depressant medications, especially in elderly populations, obscures the fact that some patients may benefit greatly from treatment. Early detection of patients who may benefit most from antidepressant medication may improve treatment decisions. We examined whether depressed patients in a large clinical trial exhibit distinct traj...

A macro vascular embolism is a well-known emergency. In contrast, cutaneous microembolism is a lesser known symptom. However, cutaneous microembolism of fingers and toes is a red flag symptom for vascular emergencies. The underlying cause may involve infectious, immunological, metabolic and physical disorders, coagulation disorders and malignancies. Early recognition can help to live safe.
