Lack of HER-2 gene amplification and association with pathological and clinical characteristics of differentiated thyroid cancer.

Human epidermal growth factor receptor 2 (HER-2) is a well recognized prognostic and predictive factor in breast cancer. However, the role of HER-2 in thyroid cancer remains controversial. The aim of this study was to evaluate HER-2 expression in differentiated thyroid cancer (DTC) and determine whether there is an association with other clinical and pathological characteristics.

Holocaust survivors: three waves of resilience research.

Children's loneliness, sense of coherence, family climate, and hope: developmental risk and protective factors.

The study examined the contributions of individual and familial variables for the prediction of loneliness as a developmental risk and the sense of coherence as a protective factor. The sample consisted of 287 children from grades 5-6. Their loneliness, sense of coherence, hope, effort, and family climate were assessed.

Differences in pathological and clinical features of breast cancer in Arab as compared to Jewish women in Northern Israel.

Breast cancer (BC) does not affect ethnic groups equally. BC mortality is higher in Israeli Palestinian Arab women than among Israeli Jewish women. This study aims to compare clinical, biological and pathological characteristics of breast cancer in the two populations.

The mediating role of internet connection, virtual friends, and mood in predicting loneliness among students with and without learning disabilities in different educational environments.

This study evaluated a multidimensional model of loneliness as related to risk and protective factors among adolescents with learning disabilities (LD). The authors aimed to identify factors that mediated loneliness among 716 adolescents in Grades 10 through 12 who were studying in high schools or in Youth Education Centers for at-risk populations. There were 334 students with LD, divided into subgroups according to disability severity (three levels of testing accommodations), and 382 students without LD.
