Home Harvard Health Blog Premenstrual dysphoria disorder: Its biology, not a behavior choice - Harvard Health Blog Posted May 26, 2017, 10:30 am Almost all women have some mild premenstrual symptoms that signal the imminent arrival of their period every month. These symptoms are typically just an annoyance and dont cause any distress. But for some women, these symptoms are much more significant. About 20% of menstruating women suffer from premenstrual syndrome, or PMS. Women with PMS have mostly physical symptoms and some minor mood disturbances caused by the changing hormone levels in the second half (or luteal phase) of the menstrual cycle. These hormone-induced symptoms can cause significant physical distress in the days leading up to menstruation. Sometimes in about 5% to 8% of menstruating women debilitating mood changes accompany these premenstrual physical symptoms. Globally this is often referred to as severe PMS, but in the United States this combination of physical symptoms and mood disturbances is called premenstrual dysphoria disorder, or PMDD. Unfortunately, women with PMDD are often misdiagnosed. Sometimes they go undiagnosed, being told they are just hormonal and need to get over it. And sometimes they are overdiagnosed. Unfortunately, it is all too common for women … Continue reading →

A moose was at the Foothills Land Conservancy land in Wilton, four years ago. Photo by Tom Oliver WILTON - The Foothills Land Conservancy will hold its annual meeting from 6:30 p.m. to 8 p.m. on Wednesday, June 14 at Academy Hill School Cafeteria in Wilton. The first portion of the event will cover the annual business meeting. Election of officers and board members will take place. The second part of the meeting will be a presentation titled Dragonflies, Butterflies, and Bumble Bees of Western Maine by University of Maine at Farmington Biology Professor Ron Butler. Dr. Butler has studied these important insect groups for many years and at many sites around the state, including the Foothills Preserve. The presentation will focus on background biology of each group, some results from three, statewide, citizen-science initiatives studying these insects, and specifically what we have learned about these important insect groups at the Foothills Land Conservation Area. The event is free and open to the public. Original post: UMF Biology professor to speak at Foothills Land Conservancy meeting - Daily Bulldog … Continue reading →

The 11th q-bio Summer School and Conference (qbSS) will be held at Colorado State University June 4-20, 2017 the first time the event has been held entirely at the CSU campus. The program was started in 2007 at Los Alamos National Laboratory and was geared toward an interdisciplinary audience, including engineers, computer scientists, biochemists, biologists and physicists. qbSS is recognized as one of the worlds best educational programs in quantitative modeling of biological processes. The core topics at the 2017 qbSS will be: single-cell gene regulation, cell signaling, synthetic biology and cancer dynamics. Participants will be introduced to statistical, mathematical, and computational tools for modeling cellular regulatory systems, and they will be engaged in numerous career-focused training and discussion sessions. This years program hasmore than 30 events open to the public including keynote talks, lectures, discussion panels and poster sessions. These events will be accessible to a broad scientific audience, and the events are free to local participants. Public Lectureswill include talks from over 20 invited speakers including two members of the National Academies: ProfessorHerbert Levine (Rice University, June 14) and ProfessorMichael Savageau (UC Davis, June 13). Career Discussion Panelsfeaturing an additional 20-plus senior scientists and experts will include:Choosing the … Continue reading →

New research published in Genome Biology finds that N-BLR, a primate-specific non-coding transcript, modulates the epithelial-to-mesenchymal transition and leads to colo-rectal cancer invasion and migration. Here to tell us about this are authors of the research George Calin and Isidore Rigoutsos. George Calin & Isidore Rigoutsos 26 May 2017 The relevance of sequence conservation in molecular biology cannot be disputed. Ever since the pioneering work of Linus Pauling and Emile Zuckerkandl in the early 60s, it has been the driving force behind numerous discoveries. By the mid-60s, Margaret Dayhoff was already leveraging computers to draw links between sequence similarity and evolutionary relationships while her Protein Atlas introduced the concept of gene families. In the more than 50 years since that time, scores of amino acid and nucleic acid sequences with various degrees of conservation among numerous organisms and viruses have been linked to fundamental pathways. Discoveries over the last 20 years have revealed striking instances of conservation in organisms separated by hundreds of millions of years of evolution. Characteristic examples include the let-7 family of the regulatory non-coding molecules known as microRNAs (miRNAs) that is conserved from worms to humans, and the tumor suppressor gene known as TP53 that is … Continue reading →
