BACKGROUND Current recommendations on how to break bad news are primarily based on expert opinion. Little is known about the association between communication practices and patients' psychological response. PATIENTS AND METHODS One-hundred and thirty-one patients with newly diagnosed melanoma were surveyed 4 months after the initial consultation at the Sydney Melanoma Unit regarding their com...
UNLABELLED Communicating "bad news" to patients and their families can be difficult for physicians. OBJECTIVE This qualitative study aimed to examine residents' perceptions of barriers to delivering bad news to patients and their family members. DESIGN Two focus groups consisting of first- and second-year medical and surgical residents were conducted to explore residents' perceptions of the...
The regulation of mitochondrial permeability, a key event in the initiation of apoptosis is governed by the opposing actions of the pro- and anti-apoptotic members of the BCL2-family of proteins. The BCL2-family can be classified further based on the number of BCL-homology (BH) domains they encode. Pathogen mediated modulation of BCL2-family members play a significant role in their ability to a...
Epidemiological studies have shown that cigarette smoking is a major risk factor for tubal ectopic pregnancy but the reason for this remains unclear. Here, we set out to determine the effect of smoking on Fallopian tube gene expression. An oviductal epithelial cell line (OE-E6/E7) and explants of human Fallopian tubes from non-pregnant women (n = 6) were exposed to physiologically relevant conc...
تنش دمای پایین یکی از مهم ترین عوامل محیطی است که عملکرد گیاهان را محدود می نماید. شبکه وسیعی از ژن های مختلف در تنظیم تحمل گیاه به این تنش نقش ایفا می نمایند. در این تحقیق، نخست 921 عدد از ژن های مذکور از تحقیقات و مقالات معتبر علمی استخراج گردید و سپس به منظور شناسایی ژن های مشابه با آنها در ژنوم کامل دو گیاه سیب (malus domestica)و انگور (vitis vinifera)، توالی آمینو اسیدی این ژن ها در گیاه م...
Solid tumors contain hypoxic cells that are resistant to radiotherapy and chemotherapy. The resistance in glioblastoma has been linked to the expression of antiapoptotic Bcl-2 family members. In this study, we found that in human glioblastoma cells hypoxia induces the phosphorylation of the Bcl-2 family protein Bad, thus protecting hypoxic cells from paclitaxel-induced apoptosis. Akt activation...
Although a causal role of genetic alterations in human cancer is well established, it is still unclear whether dietary fat can modulate cancer risk in a predisposed population. Epidemiological studies suggest that diets rich in omega-3 polyunsaturated fatty acids reduce cancer incidence. To determine the influence of fatty acids on prostate cancer risk in animals with a defined genetic lesion, ...
