LINC complexes, consisting of inner nuclear membrane SUN proteins and outer nuclear membrane KASH proteins, connect the nucleus to the cytoskeleton, transmitting forces that control the nucleus's position within the cell. But how LINC complexes affect the cytoskeleton, and thus the balance of forces across cells and tissues, is less well understood. Stewart et al. now demonstrate that the LINC ...
long exposure of uv radiation increases risk of skin diseases such as cancer and photoallergic reactions. uv-b (280-320 nm) radiation is mainly responsible for inducing skin problems. skin protection is a suitable method in the fight against ultraviolet radiation induced damage. various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...
OBJECTIVES To investigate factors influencing the effectiveness of intensive sound masking therapy on tinnitus using logistic regression analysis. DESIGN The study used a retrospective cross-section analysis. PARTICIPANTS 102 patients with tinnitus were recruited at the Sun Yat-sen Memorial Hospital of Sun Yat-sen University, China. INTERVENTION Intensive sound masking therapy was used as...
We propose a new model for the initiation of a solar coronal mass ejection (CME). The model agrees with two properties of CMEs and eruptive Ñares that have proved to be very difficult to explain with previous models : (1) very low-lying magnetic Ðeld lines, down to the photospheric neutral line, can open toward inÐnity during an eruption ; and (2) the eruption is driven solely by magnetic free ...
در این پایان نامه توزیع آماره های ترتیبی از توزیع نرمال دو متغیره و سه متغیره محاسبه می کنیم. همچنین به معرفی توزیع چوله نرمال یکریخت که با نماد sun نمایش می دهیم تابع مولد گشتاور این توزیع و برخی از خواص آن می پردازیم. نحوه ساختن توزیع sun را از توزیع نرمال سه متغیره ارائه می دهیم و نشان می دهیم که توزیع آماره های ترتیبی از توزیع نرمال سه متغیره به صورت مخلوطی از توزیع sun می شود.
OBJECTIVES The present research examined the sun protection intentions and behaviours of young people in a high risk skin cancer area using an extended theory of planned behaviour (TPB) incorporating additional social influences of group and image norms. DESIGN The study employed a prospective design to examine young people's sun protection intentions and behaviour. METHOD Participants (N=1...
Skin cancer is increasing, and prevention programs are essential. This study evaluated the impact of a skin cancer prevention program on sun-protection habits and swimming pool environments. The intervention included staff training; sun-safety lessons; interactive activities; providing sunscreen, shade, and signage; and promoting sun-safe environments. A randomized trial at 28 swimming pools in...
New information reported by researchers at the University of Texas Southwestern Medical Center in Dallas could eventually help scientists develop better ways to protect against and treat the adverse effects of too much sunlight. In a paper published in the June 1999 issue of Molecular Cell, the researchers demonstrated that the interaction between a protein called Rad23 and a protein complex kn...
BACKGROUND Ultraviolet radiation (UVR) exposure and a history of sunburn are important risk factors for skin cancer. Sunburn is more common among men, younger age groups, and people in higher income households. Sun protection measures also vary by sex, age, and socioeconomic characteristics. Associations between ambient UVR and sunburn and sun safety measures have not been quantified. DATA AN...
OBJECTIVE Despite long-standing social psychological research supporting the influence of injunctive norms (i.e., what is commonly approved or disapproved) on behavior, support for this influence on health behaviors is limited. We examined the utility of correcting misperceptions of injunctive norms for improving sun protection and whether changes in attitudes mediated the injunctive norm-inten...
