| Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face. The study -- the first to examine brain activity in chimpanzees after they attempt to match fellow chimps' faces -- offers new insight into the origin of face recognition in humans, the researchers said. | |||

| • | Assisted conception following radical trachelectomy | ||
|
Radical trachelectomy (RT) has been established as a valuable fertility-preserving treatment in women with early stage cervical cancer. A number of these women will require assisted conception which may bring certain challenges to those managing treatment. An awareness of those challenges is essential to maximize outcome in terms of live birth rates. All women who had undergone assisted conception following RT were assessed with respect to treatment management and pregnancy outcome. Pregnancy rates were good, with nine pregnancies in seven women treated. Difficulties in treatment were essentially related to isthmic stenosis. There was a clear need for trial embryo transfer (ET) prior to treatment and dilatation of the isthmus where necessary. The premature delivery rate was high (75% at <37 weeks), highlighting the importance of single ET to avoid multiple pregnancy. Assisted conception following RT is associated with a good pregnancy rate, although there is a high miscarriage and premature delivery rate. Treatment outcome should be maximized by careful patient preparation in terms of assessing the need for isthmic dilatation, and ET should be performed by an experienced operator. |

| A team of researchers has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell. The results contribute to improved understanding of the infection strategies used by viruses that attack bacterial cells and they also may help researchers to devise new ways to kill E. coli bacteria, which can be dangerous to humans. | |||

| The incidence of parasitic isopods in the fish Sphyraena obtusata was studied. The reduction in gill raker count and gill surface area was observed as a function of infestation was found to be statistically significant. Maximum reduction in respiratory surface area was observed in Ist gill arch (10.7%) and minimum (9.2%) in the IIIrd gill arch. The percentage reduction of surface area in the IInd and IVth gill arches was 10.2 and 9.7, respectively. The infestations such as, hemorrhagic lesions, anemia; encapsulation; inflammation and penetration of dactylus usually pressure atrophy often accompanied by the presence of larger parasites. This may lead to huge economic losses in commercial species of fish. | |||

| • | Larvicidal and oviposition-altering activity of monoterpenoids, trans-anithole and rosemary oil to the yellow fever mosquito Aedes aegypti (Diptera: Culicidae) | ||
| BACKGROUND: Aedes aegypti L. is the major vector of dengue fever and dengue hemorrhagic fever. In an effort to find effective tools for control programs to reduce mosquito populations, the authors assessed the acute toxicities of 14 monoterpenoids, trans-anithole and the essential oil of rosemary against different larval stages of Ae. aegypti. The potential for piperonyl butoxide (PBO) to act as a synergist for these compounds to increase larvicidal activity was also examined, and the oviposition response of gravid Ae. aegypti females to substrates containing these compounds was evaluated in behavioral bioassays.RESULTS: Pulegone, thymol, eugenol, trans-anithole, rosemary oil and citronellal showed high larvicidal activity against all larval stages of Ae. aegypti (LC50 values 10.3-40.8 mg L-1). The addition of PBO significantly increased the larvicidal activity of all test compounds (3-250-fold). Eugenol, citronellal, thymol, pulegone, rosemary oil and cymene showed oviposition deterrent and/or repellent activities, while the presence of borneol, camphor and [beta]-pinene increased the number of eggs laid in test containers.CONCLUSIONS: This study quantified the lethal and sublethal effects of several phytochemical compounds against all larval stages of Aedes aegypti, providing information that ultimately may have potential in mosquito control programs through acute toxicity and/or the ability to alter reproductive behaviors.

| • | 7.346 Synaptic Plasticity and Memory, from Molecules to Behavior, Fall 2007 (MIT) | ||
| In this course we will discover how innovative technologies combined with profound hypotheses have given rise to our current understanding of neuroscience. We will study both new and classical primary research papers with a focus on the plasticity between synapses in a brain structure called the hippocampus, which is believed to underlie the ability to create and retrieve certain classes of memories. We will discuss the basic electrical properties of neurons and how they fire. We will see how firing properties can change with experience, and we will study the biochemical basis of these changes. We will learn how molecular biology can be used to specifically change the biochemical properties of brain circuits, and we will see how these circuits form a representation of space giving rise to complex behaviors in living animals. A special emphasis will be given to understanding why specific experiments were done and how to design experiments that will answer the questions you have about the brain. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching. | |||

| • | How to Blog? [A Blog Around The Clock] | ||
Don't be too wordy. HuffPo says that 800 words is the outer-length limit for a blog post; anything longer will turn people off. No. No. No. This feeds nicely in what Ezra Klein wrote about it: The specialized posts mix with the generalized posts -- in my case, health wonkery rubs elbows with garden variety political punditry -- and the two cross-subsidize each other. The rigor of the more technical work gives you credibility in the reader's mind and adds weight to the generalist posts. The generalist posts broaden the blog's potential audience and create access points that new readers wouldn't have if you let the blog become a repository of technical commentary. This is excellent advice - blog about everything that strikes your fancy, but also sometimes blog about your area of expertise. Mix it up, topic-wise, but also mix-it up format-wise: videos, pictures, one-liners, linkfest, short posts and, YES, long essays, especially in your area of expertise. If you write a long essay in your area of expertise, people WILL read. Why? Because your blog post is likely to contain information they can not find anywhere else on the Web, let alone in the media. So, even if you mostly post a bunch of quick-and-dirty posts on various topics, when you have something special to say, don't be afraid to write 2000 or 3000 or 4000 or 5000 words. People will read that. And bookmark it. And put it on social networks. And e-mail it to friends. And discuss it in the comments. And respond to them on their own blogs. Those posts are the real gems of the blogosphere. And how do you become an expert on a topic? You could go the usual way, through school or practice. But you can also become an expert if you constantly blog about something over the years. You dig through the literature, you read other bloggers who write about it, you get corrected by commenters, and soon become a knowledgeable and respected authority. You may still know less (but not always) than a person who got a PhD in the topic, but you will certainly know more than a journalist who writes on that topic because the editor said so - because you write, and thus learn, with passion.

| NALP3 inflammasome functional polymorphisms and gout susceptibility. Cell Cycle. 2009 Jan 31;8(1) Authors: Miao ZM, Zhao SH, Yan SL, Li CG, Wang YG, Meng DM, Zhou L, Mi QS Gout is the most common autoinflammatory arthritis characterized by elevated serum urate and recurrent attacks of intra-articular crystal deposition of monosodium urate (MSU). Although the pathogenesis of gout is still unclear, accumulated studies indicate that genetic factors trigger gout development, including some susceptibility genes that control the production and clearance of urate and lead to hyperuricemia. However, the epidemiological evidence suggests that only less than 10% of hyperuricemia patients develop gout, indicating that other genes unrelated to the urate metabolism may also contribute to th... | |||
