—Many songbirds are seasonally frugivorous and eat primarily fruit during migration and insects or seeds during nonmigratory periods. Previous work has suggested that most wild fruits may have inadequate protein for birds. Assessing the nutritional adequacy of fruit requires knowing the protein requirements of birds in relation to the composition of available fruits. We tested predictions of tw...

objective: : loneliness is one of the fundamental problems of old people that many factors are involved in the development or aggravation of that. any factor, such as migration, that reduces the kinship network, can be considered as effective factor. there are many studies about migration as a common phenomenon in most rural of iran, but few answered to this question: what is the effects of mig...

objective(s): berberine is one of the main alkaloids and it has been proven to have different pharmacological effects including inhibition of cell cycle and progression of apoptosis in various cancerous cells; however, its effects on cancer metastasis are not well known. cancer cells obtain the ability to change their chemokine system and convert into metastatic cells. in this study, we examine...

The population development of the 1998 year class of the bivalve Macoma balthica was studied by repeated sampling of a tidal flat area in the eastern Dutch Wadden Sea from May 1998 to August 2000. The juveniles migrated twice, once in mid-1998 from their primary settlement locations in the low sandy intertidal to the nursery in the high intertidal (spring migration, 25% of all juvenile M. balth...

ventriculoperitoneal (vp) shunt is one of the most common pediatric neurosurgical procedures. it has various complications that may have serious consequences such as shunt dysfunction, and unusual migration. although, migration of shunt catheter to bladder, heart, umbilicus, rectum, pulmonary artery, and stomach has been reported, migration to vagina is a rare one. in this report we present a 1...

Airway smooth muscle cells produce extracellular matrix proteins, which in turn can promote smooth muscle survival, proliferation and migration. Currently available therapies have little effect on airway smooth muscle matrix production and migration. Peroxisome proliferator-activated receptor (PPAR) ligands are reported to decrease migration and matrix production in various cell lines. In this ...

Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

Bipolar hemiarthroplasty of the hip joint has been used for the treatment of femoral neck fractures and osteonecrosis of the femoral head.1-2 This prosthesis originally was believed to decrease shear stress on the acetabular cartilage, resulting in decreased migration.3,4 However, osteolysis of the acetabulum and migration of the head have been reported after bipolar hemiarthroplasty.5-7 This a...
