Гостевая лекция Института биоинформатики. Подробнее: http://bioinformaticsinstitute.ru/lectures/1218
Несмотря на несерьезное название, на лекции разговор пойдет о важной проблеме в работе биоинформатика, почти любая реальная задача которого связана с обработкой и анализом больших данных. И решить задачу нужно не только правильно, но и эффективно. Процесс решения можно условно разделить на две части: «придумать», как решать, и «обучить» этому компьютер. И на лекции речь пойдет именно об эффективном «обучении».
Наивно реализованные алгоритмы работают неприемлемо долго, когда дело доходит до гигабайтов реальных данных. От биоинформатика уже требуются не просто базовые навыки программирования, но и знание технических нюансов. И даже у профессионального программиста уйдет немало времени, например, чтобы выгодно использовать возможности Hadoop при работе с Big Data. Так можно ли современному ученому обойтись без тщательного изучения кучи языков, библиотек и фреймворков и сосредоточиться именно на решении?
Ядерный век прошел, и становится все понятнее, что в фокусе науки 21-го века будут живые системы, медицина, и человек во всех его проявлениях. Здесь осуществляются самые масштабные финансовые вливания, и на эту отрасль человечество возлагает самые большие надежды. Все чаще слышатся предметные обсуждения тем, казавшихся еще недавно научной фантастикой: сможет ли человечество победить старение, рак, и другие смертельные заболевания? Сможет ли менять свой геном по собственному желанию? Будем ли мы хозяевами своим телам в той же мере, как мы хозяйничаем на Земле?
Многие десятилетия биология и медицина развивались как описательные науки. Однако по мере созревания и накопления информации, любая наука рано или поздно переходит на более точный язык - язык математики. Проект "Геном человека" обеспечил технологический прорыв, который будет питать науку о живом еще много лет - но который также поставил много новых глобальных вопросов перед современными учеными.

Гостевая лекция Института биоинформатики, 9 октября 2014. Лектор -- Мария Шутова (ИоГЕН РАН).
За последние десять лет плюрипонтентные клетки стали героями двух Нобелевских премий и многих тысяч научных и научно-популярных статей. Их уникальная возможность превращаться в любую клетку взрослого организма до сих пор дает пищу для ума как биологам развития, так и ученым, ищущим способы лечения генетических заболеваний. В лекции будет рассказано о двух типах плюрипотентных клеток: "естественных" (эмбриональные стволовые клетки) и "искусственных" (индуцированные плюрипотентные стволовые клетки). Отдельно мы остановимся на том, как знания о работе транскрипционных факторов помогли репрограммировать клетки, и как эти "искусственные" плюрипотентные клетки можно использовать в медицине.
В своей лекции Андрей Афанасьев рассказал о стартапах в биотехе и биоинформатике и своем биоинформатическом проекте iBinom, разобрал несколько биотехнологических проектов глазами инноваторов и инвесторов, а также коснулся вопроса поиска инвестиций и поделился личным опытом взаимодействия с венчурными фондами и институтами развития.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule

2. Genetic testing
An individual has symptoms or
An individual is at risk of developing a
disease with a family history.
DNA molecular testing:
A type of testing that focuses on the
molecular nature of mutations associated
with the disease.
3. Complications
Many different mutations can cause
symptoms of a single disease.
BRCA1 and BRCA2 are implicated in the
development of breast and ovarian cancer.
Hundreds of mutations can be found in these
genes; the risk of cancer varies among the
mutations.
General screening and genetic testing are different
(mammograms vs. testing for specific mutations in
the gene).
4. Genetic testing:
Prenatal diagnosis: is the fetus at risk?
(amniocentesis or chorionic villus
samples analyzed).
Newborns can be tested for PKU, sickle
cell anemia, Tay-Sachs.
5. Methods of Genetic Testing
Restriction Fragment Length
Polymorphism analysis:
Loss or addition of a RE site is analyzed.
RFLP is a DNA marker.
RFLPs are useful for:
Mapping the chromosomes.
Finding out different forms of genes/sequences.
6. RFLPs
RFLP’s may be changes in the gene of
interest (such as with sickle cell).
Often, RFLP’s are associated with, but not in,
the gene of interest. A RFLP which is very
near the allele of interest will usually indicate
the presence of the allele of interest.
RFLP’s can be used to follow a genetic
lineage (in essence, a specific chromosome)
in a population, and is a useful tool in
population biology.
16. Microsatellites and VNTRs as
DNA Markers
Analysis of “microsatellites” ( short tandem repeats or
STR’s, 2-4 bases repeat), and VNTR’s (Variable
number of tandem repeats, 5- 10’s of bases repeat)
sequences is used in many genetic approaches.
Repeated sequences are often more variable (due to
replication errors and errors in crossing over) than
non repeating sequences, therefore lots of alleles are
generally present in a population.
In other words, two individuals have a higher chance
of genetic differences at STR’s and VNTR’s than at
most sequences in the DNA.
18. Analysis of Microsatellites and
VNTR’s
One way of thinking about these analyses is that
this is a specialized RFLP analysis, the power is
that there are lots of alleles in a population, so
there is a high chance that two individuals will be
different in their genotypes (informative).
Two techniques are common in these analyses:
Southern blot followed by hybridization with a probe that
will detect the sequence (as in RFLP analysis).
PCR with a pair of primers which flank the variable
sequence.
19. Applications
Population studies: finding differences in
allele frequencies can identify separate
populations (not interbreeding).
Locating specific genes: associating a
specific VNTR allele with a genetic disease
can help localize the gene to a region of the
chromosome, or trace the allele through a
pedigree.
DNA typing: paternity testing (also useful in
population studies, in animal breeding etc.)
and in forensic analysis.
20. DNA Typing in
Paternity Testing
• Comparison of
VNTR’s can definitely
exclude an individual
from being the parent
of a child (neither
allele the child has is
present in the alleged
father).
21. DNA Typing in Paternity Testing
• Proving paternity is more difficult, and relies on statistical
arguments of the probability that the child and the alleged
father are related. Multiple loci (different VNTR’s) must be
examined to provide convincing evidence that the alleged
father is the true father. The same statements (exclusion
versus proof of identity) are true for forensic arguments.
Ethnicity of the accused is a factor: allele frequencies for
VNTR’s are different in different population, be they elk or
human., and often the frequencies (which are the basis of the
statistical arguments) are not known for a specific group.
22.
23.
24. Finding a Gene: Chromosome
Walking
Identifying the gene associated with a specific
disease requires years of work.
The first step is to identify the region of the
chromosome the gene is in (pedigree analysis,
identifying breaks in chromosomes which cause
the disease, etc.)
Once the gene has been localized to a region of a
chromosome, is to “walk” along the chromosome.
The walk starts at a sequence known to be
nearby, and continues until the gene of interest is
located.
25. Isolation of Human Genes
Positional cloning: Isolation of a gene
associated with a genetic disease on
the basis of its approximate
chromosomal position.
26. Cystic Fibrosis Gene
Cystic fibrosis disease is a common lethal
disease inherited as an autosomal recessive
manner.
Identify RFLP markers linked to the CF gene.
Identify the chromosome on which the CF gene is
located.
Identify the chromosome region on which the CF
gene is located (finer mapping).
Clone the CF gene between the flanking markers.
Identify the CF gene in the cloned DNA.
Identify the defects in the CF gene.
27. RFLP markers linked to the
CF gene (linkage studies)
Screen many individuals in CF
pedigrees with a large number of
RFLPs.
Use Southern blot analysis and hybridize
with probes to identify different forms.
Establish a linkage between the markers
and the occurrence of the disease.
28. Which chromosome?
Use in situ hybridization, where
chromosomes are spread on a
microscope slide, and hybridized with a
labeled probe, results are analyzed by
autoradiography.
A 3H-labeled RFLP probe showed that CF
gene is located on chromosome 7.
29. Which chromosomal region?
Search other RFLPs located on the chr. 7, to
find ones that are linked to the CF gene.
Again, use the pedigrees and test the DNA
for associated RFLP markers.
Two closely linked flanking markers (one marker
on each side of the CF gene) were found that are
0.5 map units apart (~500.000 bp).
Their locations were 7q31-q32.
