PURPOSE Few epidemiologic studies have investigated aggressive periodontitis in Koreans, but such studies of disease prevalence and other clinical characteristics would be invaluable in providing proper treatment. The aim of this study was to assess the prevalence of aggressive periodontitis and to measure the extent of associated periodontal breakdown. METHODS The study population consisted ...

The "unresolved" state of mind with respect to loss or trauma as assessed in the Adult Attachment Interview is common in clinical and forensic groups, as well as in mothers whose infants are classified as disorganized in their attachment relationship to them. However, questions remain about what the unresolved state represents and what factors predict the unresolved state. This case controlled ...

BACKGROUND AND PURPOSE Chronic infectious diseases may increase the risk of stroke. We investigated whether periodontal disease, including periodontitis and gingivitis, is a risk factor for cerebral ischemia. METHODS We performed a case-control study with 303 patients examined within 7 days after acute ischemic stroke or transient ischemic attack, 300 population controls, and 168 hospital con...

BACKGROUND Loss of the transmembrane mucin, Muc-1, is a molecular correlate of the acquisition of uterine receptivity to embryo adhesion in most species examined. In macaques, two distinct adhesion events occur at opposite sides of the uterus. Attachment to the secondary site is delayed relative to the primary site. The aim was to determine if Muc-1 is removed at secondary sites prior to tropho...

Significant spontaneous fetal loss of unknown cause occurs in North American commercial swine. About 30% of conceptuses, thought to be genetically normal, are lost during the peri-attachment period. An additional 20% are lost at mid-pregnancy. Littermate endometrial and trophoblast biopsies were studied by quantitative real-time PCR for gene expression, and immunohistochemistry for protein expr...

Study of attachment in the 1970s and 1980s focused on operationalizing and validating many of the tenets of attachment theory articulated in Bowlby’s landmark trilogy, Attachment and Loss (Bowlby, 1982, 1973, 1980), robustly underscoring the central role of child to parent attachment in the child’s development and mental health. Attachment theory and its implications have long interested clinic...

BACKGROUND Grieving individuals demonstrate attentional bias toward reminders of the deceased versus neutral stimuli. We sought to assess bias toward reminders of the deceased versus a living attachment figure and to evaluate similarities and differences in the neural correlates of deceased- and living-related attention. We also sought to identify grief process variables associated with decease...

Research on antecedents of organized attachment has focused on the quality of caregiving received during childhood. In recent years, research has begun to examine the influence of genetic factors on quality of infant attachment. However, no published studies report on the association between specific genetic factors and adult attachment. This study examined the link between the 5-HTTLPR promote...
