BACKGROUND Young cancer patients may occasionally face infertility and premature gonadal failure. Apart from its direct effect on follicles and oocytes, chemotherapy may induce ovarian toxicity via an impact on the entire ovary. The role of doxorubicin in potential ovarian failure remains obscure. Our intention was to elucidate doxorubicin-related toxicity(More)
This study compared qualitative aspects of problem solving among suicide attempters, suicide ideators, and nonsuicidal patients. The subjects completed a suicidal intent scale and a problem-solving task involving three dilemmas. Problem solving was analyzed along eight qualitative categories: versatility of the various solutions, reliance on self versus(More)
INTRODUCTION Chemotherapy may induce deleterious effects in normal tissues, leading to organ damage. Direct vascular injury is the least characterized side effect. Our aim was to establish a real-time, in vivo molecular imaging platform for evaluating the potential vascular toxicity of doxorubicin in mice. METHODS Mice gonads served as reference organs.(More)
Ovarian failure is a-known side-effect observed in women treated for cancer. Doxorubicin (DXR) was found to be detrimental to MII mouse oocytes. We aimed at characterizing the effect of DXR on germinal vesicle (GV) oocytes that comprise the majority of oocytes within ovaries encountering chemotherapy. Mouse follicles and oocytes were exposed to DXR in(More)
Three-hundred ninety-three adolescents from six schools participated in a study aimed at examining the effectiveness of an experiential suicide prevention program with regard to suicidal tendencies, hopelessness, ego identity, and coping ability. The subjects were randomly divided into experimental (n = 215) and control (n = 178) groups. The experimental(More)
Pigment epithelium-derived factor (PEDF) is highly expressed in the female reproductive system and is subjected to regulation by steroid hormones in the ovary. As the uterine endometrium exhibits morphological and functional changes in response to estrogen (E2) and progesterone (P4), we aimed at characterizing the expression of PEDF in this component of the(More)
The physiological function of the female reproductive organs is hormonally controlled. In each cycle, the reproductive organs undergo tissue modifications that are accompanied by formation and destruction of blood vessels. Proper angiogenesis requires an accurate balance between stimulatory and inhibitory signals, provided by pro- and anti-angiogenic(More)
Certain classes of chemotherapies may exert acute vascular changes that may progress into long-term conditions that may predispose the patient to an increased risk of vascular morbidity. Yet, albeit the mounting clinical evidence, there is a paucity of clear studies of vascular toxicity and therefore the etiology of a heterogeneous group of(More)
OBJECTIVE To determine whether supplementing granulosa cells cultures with pigment epithelium-derived factor (PEDF) can protect them from oxidative stress. DESIGN We used either granulosa cell line or human primary granulosa cell culture from women undergoing in vitro fertilization (IVF) treatments. SETTING University research facilities. ANIMAL(S)(More)
