BACKGROUND Aging is an irreversible natural process characterized by a decline in both the physical and mental status of individuals. Because of multiple factors, this process and its consequences vary greatly between individuals. A successful aging (SA) is the target of current health policies and well-being of individuals. Knowing the factors that contribute to SA and its barriers would trans...

Introduction:Foreign body aspiration is usually a serious condition that is most common among the pediatric population, and rare in adults. In adults, aspiration may be tolerated for a long time.Case Reports:Our first case is a 38-year-old man who presented with a 2-day history of swallowing a foreign body. He was completely asymptomatic. Chest X-ray revealed the presence of 5-cm foreign object...

Endothelial vasomotor function decreases with increasing age. Extracellular superoxide dismutase (ecSOD) protects against vascular dysfunction in several disease states. The purpose of this study was to determine whether endogenous ecSOD protects against endothelial dysfunction in old mice. Vasomotor function of the aorta was studied ex vivo in wild-type (ecSOD(+/+)) and ecSOD-deficient (ecSOD(...

In the village of Badirri, Jalilabad district, coprological studies were conducted and 18.8% ganguleteracidosis infections detected among 3-month-old ducks, 31.3% 6-month-olds, 43.8% 9-month-olds. And in Karayar, examination revealed infection ganguleterakis 36.0%, drepaidotenia 23.0%, amidostoma 27.2%, 6-month-old 29.4%, drepanidotenia 17.1%, 20.0%, 9-month-old 30.0%, 16.0%, 25.0%, adult ducks...

The past year has yielded many insights and a few surprises in the field of axonal regeneration. The identification of oligodendrocyte-myelin glycoprotein as an inhibitor of axonal growth, and the discovery that the three major myelin-associated inhibitors of CNS regeneration share the same functional receptor, has launched a new wave of studies that aim to identify the signaling components of ...

BACKGROUND There is little research evidence as to whether general adult psychiatry or old age psychiatry should look after old people with enduring mental illness. AIMS To compare the extent to which general adult and old age psychiatric services meet the needs of older people with enduring mental illness. METHOD A total of 74 elderly patients with functional psychiatric disorders were ide...

By the age of 80 yr, the skeletal muscles of men and women decrease in mass and maximum force by approximately 30%. Severe contraction-induced injury may contribute to these age-related declines. One to two months after a 225 lengthening contraction protocol (LCP), muscles of young/adult male mice recovered completely, whereas those of old male mice sustained deficits of approximately 15% in ma...

Background & Aims: In developed countries mental disorders are recognized by screening questionnaires and clinical interviews. Since there is a limited number of epidemiological studies about mental disorders in Iranian population, the present study was performed to find the prevalence and type of mental disorders among Kerman residents older than 15 years old. Method: At the first step, GH...

The pancreas of adult and old mice of various ages has been shown to contain a lipid fraction which is not normally stainable, but which is unmasked by the action of the lipid-solvent methanol: chloroform (1:2 v/v) and hence becomes stainable by the acid haematein reaction. This fraction seems to be contained in the zymogen granules of adult and old mice, but is absent from the pancreas of tto ...

Erythropoietic repopulating abilities of fetal liver cells and young and old adult marrow cells were compared as follows: Equal numbers of cells from a donor of each age were mixed with a constant portion of cells pooled from genetically distinguishable competitors. These mixtures were transplanted into stem cell-depleted recipients, and the proportions of recipient hemoglobin that were donor t...
