Developmental Origins of Brain Circuit Architecture and Psychiatric Disorders (Day 1)
 
07:43:30
Developmental Origins of Brain Circuit Architecture and Psychiatric Disorders (Day 1) Air date: Thursday, November 29, 2018, 8:30:00 AM Category: Conferences Runtime: 07:43:30 Description: Developmental neurobiology is a critical ingredient for understanding the structure and function of the human brain. Classical anatomists recognized that the brain’s component architecture is most accurately seen through the lens of neurodevelopment. This principle has been further applied to understand the brain’s internal connections, capacity for learning, and functional maturation. By drawing together researchers from different fields, this symposium aims to generate healthy discussion and debate on how advances in neurodevelopment have shaped and will continue to shape, our understanding of brain architecture and function, both in health and in psychiatric disorders.

The AML genome(s): Mutations in four dimensions Air date: Wednesday, September 30, 2015, 3:00:00 PM Category: WALS - Wednesday Afternoon Lectures Runtime: 01:10:11 Description: NIH Director’s Wednesday Afternoon Lecture Series For many years, Dr. Ley's laboratory has used mouse models of acute myeloid leukemia (AML) to establish key principles of AML pathogenesis. The lab established that the initiating event for Acute Promyelocytic Leukemia is the PML-RARA fusion gene created by the t(15;17) that is found in nearly all patients with this disease. The roles of cooperating mutations and the cellular milieu for APL pathogenesis have also been established. In collaboration with the Genome Institute at Washington University, the investigators of the Genomics of AML PPG (TJ Ley, PI) sequenced the first human cancer genome (a patient with AML) and the first mouse cancer genome (from the mouse model of APL), and have discovered several new recurrent mutations that are important for AML pathogenesis and outcomes, including recurring mutations in DNMT3A and IDH1/2, among many others. These data are now being correlated to RNA expression, DNA methylation, protein abundance and modification, and clinical datasets. These efforts will hopefully lead to new tests to better establish prognosis, and new approaches for the therapy of patients with this disease.

Analysis of Genetic Association Studies
 
51:28
Teri Manolio, M.D., Ph.D. Director, Office of Population Genomics, NHGRI. Genetics for Epidemiologists: Applications of Human Genomics to Population Sciences, was a short course for investigators and trainees in the field of epidemiology and related population-based sciences. It was conducted by the National Human Genome Research Institute (NHGRI) on May 13-14, 2008 at Northwestern University in Chicago. The goal of Genetics for Epidemiologists (GFE) was to familiarize epidemiologists and population-based researchers with recent developments in the theory and methods of human genetics that might be applied to the study of the distribution, natural history and etiology of diseases in populations. The course consisted of eight one-hour lectures and focused on the interface between genetics and epidemiology. Emphasis was on the application of modern human genome analysis methodologies to studies of human populations through the design, conduct, analysis, and interpretation of studies which effectively answer the epidemiologic question of interest. GFE is co-sponsored by the Office of Population Genomics, NHGRI, and the Department of Preventive Medicine at Northwestern University's Feinberg School of Medicine. These videocasts are provided as an educational tool for epidemiologic investigators interested in learning more about applying genomics to their work. More: http://www.genome.gov/27026645
The Making of “Fungible Open Data” in Biomedical Research: Governance, Epistemic Trust, Public Good
 
01:08:16
This talk discusses the epistemic, societal, and ethical implications of making publicly available and reusing open data from biomedical research. Today, making scientific data open is promoted by funding agencies and lawmakers as means to speed up the research process, leverage public investments in large-scale data collections, and increase public trust in science. Especially in genomics research, scientists are increasingly encouraged, and sometimes required, to make their data openly available right after data collection and prior to publication. These policies are challenging well-established community norms, scientific collaborative practices, and epistemic processes for knowledge validation. Moreover, scientists are concerned about the possibility for third parties to exploit their data inappropriately, unethically, or in misleading ways. The main case study is the FaceBase Consortium, a consortium for data sharing operating in the craniofacial research domain. Data types include facial images, metrics for facial norms, gene expression data, and results from genome-wide association studies (GWAS). The reuse of these various “kinds” of data has applications beyond their original context of production that span from the design of mobile apps for facial recognition to the development of forensic DNA phenotypic technologies.

Dr. Lance Waller from Emory University presents a lecture titled "Data Issues: Multiple Testing, Bias, Confounding, & Missing Data." View Slides https://drive.google.com/open?id=0B4IAKVDZz_JUczRSd0NucjlhT00 Lecture Abstract Once data are scraped, wrangled, linked, merged, and analyzed, what information do they reveal and can we trust the resulting conclusions? In this presentation, we define and review data issues relating to the analysis and interpretation of observational data from the field of epidemiology and consider implications for data science, especially regarding the goal of moving from big data to knowledge. Specifically, we explore concepts of bias, confounding, effect modification, and missing/mismeasured data as applied to data science. We provide an analytic context based on sampling concepts and explore relevant literature and tools from epidemiology, biostatistics, computer science, and data science. As with many issues in data science, the full applicability of the concepts is very much a work in progress and present multiple opportunities for future development. About the Speaker Lance A. Waller, Ph.D. is Rollins Professor and Chair of the Department of Biostatistics and Bioinformatics, Rollins School of Public Health, Emory University.

Genetic studies on Jews | Wikipedia audio article

This is an audio version of the Wikipedia Article: Genetic studies on Jews Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping!

These studies investigate the origins of various Jewish populations today. In particular, they investigate whether there is a common genetic heritage among various Jewish populations. Studies of autosomal DNA, which look at the entire DNA mixture, show that Jewish populations have tended to form relatively closely related groups in independent communities with most in a community sharing significant ancestry. For populations of the Jewish diaspora, the genetic composition of Ashkenazi, Sephardi, and Mizrahi Jewish populations show significant amounts of shared Middle Eastern ancestry. According to Behar and colleagues (2010), this is "consistent with a historical formulation of the Jewish people as descending from ancient Hebrew and Israelites of the Levant" and "the dispersion of the people of ancient Israel throughout the Old World". Jews living in the North African, Italian, and Iberian regions show variable frequencies of admixture with the historical non-Jewish population along the maternal lines. In the case of Ashkenazi and Sephardi Jews (in particular Moroccan Jews), who are closely related, the source of non-Jewish admixture is mainly southern European. Behar and colleagues have remarked on an especially close relationship between Ashkenazi Jews and modern Italians. Some studies show that the Bene Israel and Cochin Jews of India, and the Beta Israel of Ethiopia, while more closely resembling the local populations of their native countries, have some ancient Jewish descent.

이화지식나눔특강 시리즈, 식품영양학과 고광석 교수의 ‘4.0시대의 먹거리( Food In The 4.0 Era)’
 
45:52
이화지식나눔특강 시리즈, 식품영양학과 고광석 교수의 ‘4.0시대의 먹거리(Food In The 4.0 Era: Eating And Living Well On My Own? )’ 본교 최고의 연사진과 함께하는 2017-2학기 ‘이화지식나눔특강’ 시리즈 다섯번째 강의인 식품영양학과 고광석 교수의 ‘4.0 시대의 먹거리: 나 혼자 잘 먹고 잘 살기?’가 11월 16일(목) ECC B144호에서 개최됐다. 대학인문역량강화사업(CORE 사업)의 일환으로 마련된 이번 특강에서는 4.0시대의 도래와 빅데이터 기술 발전이 식품·외식산업 및 영양과학 분야에 어떻게 적용되는지 살펴보고, 향후 식생활 및 영양 분야가 맞이할 변화와 미래에 대한 이야기를 나누었다. 1986년 개봉영화 ‘The Fly’의 한 장면을 소개하며 특강을 시작한 고광석 교수는 4차 산업의 개념 설명과 함께 ‘기술의 발전이 어떻게 식품·외식산업에서 영향을 미칠 것인가’라는 주제로 특강을 전개했다. 그는 국내외에서 인기를 얻고 있는 외식 관련 어플리케이션 사례들을 소개하며 “끝을 알 수 없는 기술의 발전으로 외식산업 사업모델이 넓어지고 있다”고 설명했다. 고광석 교수는 빅데이터 기술의 핵심이 바로 데이터 분석을 통한 ‘예측(Prediction)’이고, 예측 기술의 효과적 활용이 결국 4.0 시대의 열쇠가 될 것이라고 언급했다. 이어 빅데이터 기반의 레시피 개발 프로그램인 ‘IBM Chef-Watson’과 식품·외식 분야 인공지능 활용 사례를 소개하며 “전 세계의 요리 정보를 데이터화하여 사용자 취향에 따라 새로운 레시피를 창조하는 Chef-Watson이 향후 식품·외식 산업 발전에 있어 하나의 이정표가 될 수 있을 것”이라고 덧붙였다. 뿐만 아니라 고 교수는 영양과학의 발전으로 촉발된 만성질환에 대한 연구가 활발해지고 있고 이는 개인맞춤형 헬스케어 기술 개발로 귀결된다고 말했다. 빅데이터를 활용한 헬스케어 분야에서 가장 중요한 것은 바로 ‘정확한 영양학(Precision Nutrition)’이며, 이를 통해 축적된 영양 및 질병 데이터를 활용하여 질병 발생 가능성이 높은 개인에게 맞춤형 필수 영양소를 공급함으로써 궁극적으로 질병예방 효과를 가져올 수 있음을 강조했다. 끝으로 이러한 원리를 기반으로 한 ‘유전자 동의보감 사업’이 현재 진행 중으로 향후 국민건강증진과 신성장동력 마련에 큰 도움이 될 것이라 예측하며 특강을 마무리했다. 고광석 교수는 미국 University of California Davis에서 영양생물학 박사 학위를 취득한 후 University of Southern California Medical School에서 박사후 연구원으로서 영양과 질병 관련 연구의 기틀을 마련하였다. 2012년부터 본교 식품영양학과 교수로 재직 중이며 현재까지 Hepatology, Journal of Clinical Investigation, Gastroenterology, Journal of Biological Chemistry 등 SCI 저널을 포함한 국내외 저널에 30여 편 이상의 논물을 게재하였다. 또한 이화여대 생명윤리위원회(IRB) 위원장, 신산업융합대학 평의원, 입학처 기획관리위원으로 봉사하고 있으며 이화남성중창단 멤버로서 본교 재학생들에게 매년 큰 즐거움을 주고 있다. 현재 본교 식품영양학과 질병생리학실험실에서 질병관련 영양학 연구를 수행하고 있다.

Defining the Spectrum of Resistance to be Targeted Anti-Cancer Therapeutics
 
01:03:16
Air date: Wednesday, September 05, 2012, 3:00:00 PM Category: Wednesday Afternoon Lectures Description: Dr. Levi Garraway has made seminal research contributions in cancer genomics, drug resistance, and genomics-driven (or "personalized") cancer medicine. He published the first genome sequencing studies of aggressive primary prostate cancer, and has led other major sequencing initiatives in prostate cancer, melanoma and head/neck cancers. This work identified multiple new cancer genes and uncovered mechanisms by which complex rearrangements arise. At the Broad Institute, he leads the Cancer Cell Line Encyclopedia, a collaboration with Novartis that involves a genomic and pharmacological study of ~1000 human cancer cell lines to characterize sensitivity and resistance to anticancer agents. Dr. Garraway is perhaps best known for his contributions to precision cancer medicine. He described the first high-throughput adaptation of a genomic technology to profile human tumors for hundreds of "actionable" cancer gene mutations. This provided a basis for tumor mutation profiling as a means to stratify cancer patients for clinical trial enrollment and, in the future, optimal therapeutic choices. He also demonstrated the promise of massive parallel sequencing as a clinical tumor genomic profiling approach. This research has inspired personalized medicine initiatives at many cancer centers worldwide. Dr. Garraway has been the recipient of several awards and honors, including the Minority Scholar Award from the American Association of Cancer Research, the Partners in Excellence Award, and the Burroughs-Wellcome Fund Career Award in the Biomedical Sciences. In the fall of 2007, he was awarded one of the first prestigious New Innovator Awards from the National Institutes of Health. In 2009, he was inducted into the American Society for Clinical Investigation. For more information go to http://wals.od.nih.gov Author: Levi A.

In computer science AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".The scope of AI is disputed: as machines become increasingly capable, tasks considered as requiring "intelligence" are often removed from the definition, a phenomenon known as the AI effect, leading to the quip in Tesler's Theorem, "AI is whatever hasn't been done yet." For instance, optical character recognition is frequently excluded from "artificial intelligence", having become a routine technology. Modern machine capabilities generally classified as AI include successfully understanding human speech, competing at the highest level in strategic game systems (such as chess and Go), autonomously operating cars, and intelligent routing in content delivery networks and military simulations. Artificial intelligence was founded as an academic discipline in 1956, and in the years since has experienced several waves of optimism, followed by disappointment and the loss of funding (known as an "AI winter"), followed by new approaches, success and renewed funding. For most of its history, AI research has been divided into subfields that often fail to communicate with each other. These sub-fields are based on technical considerations, such as particular goals (e.g. "robotics" or "machine learning"), the use of particular tools ("logic" or artificial neural networks), or deep philosophical differences. Subfields have also been based on social factors (particular institutions or the work of particular researchers).The traditional problems (or goals) of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception and the ability to move and manipulate objects. General intelligence is among the field's long-term goals. Approaches include statistical methods, computational intelligence, and traditional symbolic AI. Many tools are used in AI, including versions of search and mathematical optimization, artificial neural networks, and methods based on statistics, probability and economics. The AI field draws upon computer science, information engineering, mathematics, psychology, linguistics, philosophy, and many others. The field was founded on the claim that human intelligence "can be so precisely described that a machine can be made to simulate it". This raises philosophical arguments about the nature of the mind and the ethics of creating artificial beings endowed with human-like intelligence which are issues that have been explored by myth, fiction and philosophy since antiquity. Some people also consider AI to be a danger to humanity if it progresses unabated. Others believe that AI, unlike previous technological revolutions, will create a risk of mass unemployment.In the twenty-first century, AI techniques have experienced a resurgence following concurrent advances in computer power, large amounts of data, and theoretical understanding; and AI techniques have become an essential part of the technology industry, helping to solve many challenging problems in computer science, software engineering and operations research.

It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's inner core.Use of nickel (as a natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who personified the fact that copper-nickel ores resisted refinement into copper. An economically important source of nickel is the iron ore limonite, which often contains 1–2% nickel. Nickel's other important ore minerals include pentlandite and a mixture of Ni-rich natural silicates known as garnierite. Major production sites include the Sudbury region in Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, and Norilsk in Russia. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant. Historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 9% of world nickel production is still used for corrosion-resistant nickel plating. Nickel-plated objects sometimes provoke nickel allergy. Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements (the others are iron, cobalt, and gadolinium) that are ferromagnetic at approximately room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is valuable in modern times chiefly in alloys; about 68% of world production is used in stainless steel. A further 10% is used for nickel-based and copper-based alloys, 7% for alloy steels, 3% in foundries, 9% in plating and 4% in other applications, including the fast-growing battery sector. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms a ...

It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's inner core.Use of nickel (as a natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who personified the fact that copper-nickel ores resisted refinement into copper. An economically important source of nickel is the iron ore limonite, which often contains 1–2% nickel. Nickel's other important ore minerals include pentlandite and a mixture of Ni-rich natural silicates known as garnierite. Major production sites include the Sudbury region in Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, and Norilsk in Russia. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant. Historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 9% of world nickel production is still used for corrosion-resistant nickel plating. Nickel-plated objects sometimes provoke nickel allergy. Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements (the others are iron, cobalt, and gadolinium) that are ferromagnetic at approximately room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is valuable in modern times chiefly in alloys; about 68% of world production is used in stainless steel. A further 10% is used for nickel-based and copper-based alloys, 7% for alloy steels, 3% in foundries, 9% in plating and 4% in other applications, including the fast-growing battery sector. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site.
