stem cell research is yet to be advanced , once fully developed can alleviate human suffering, this ppt reviews the contemporary evidence, pitfalls and challenges
A stem cell is a "blank" cell that can give rise to multiple tissue types such as a skin, muscle, or nerve cell.
Under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions.
iPSCs are pluripotent; unlike ESC, iPSCs are not derived from the embryo, but instead created from differentiated cells in the lab through a process – cellular reprogramming.
Imagine that you have been told you have an illness that cannot be cured or what if your body has been irreversibly paralysed. There is no hope. But there is a science that could change that. It’s Called Stem Cell Research and it’s an important step in the medical revolution. But it comes with controversies as it uses Human Embryos’ as Raw Material.
But something astounding happened in the year 2006 that removed the usage of surplus embryos from the equation altogether. It’s about a brand new technology that can turn back the clock on your body cells. This is cutting edge of science where new developments are happing all the time. The iPSCs could be the potential medicine of 21st century. So what are stem cells? Why do they Matter? What are iPSCs and how it changed the biological rules?

“Stem Cell, Possibilities And Utility In Health sector” Ajit Tiwari
The role of stem cells in basic biological processes in vivo, namely in development, tissue repair and cancer.
Remarkable progress has been achieved in studying stem cells. The most exciting use of cultured stem cells is the promise for curing many devastating diseases like Parkinson's and diabetes. However, more basic research remains before stem-cell based therapy is widely used.
ES cells have the most capacity to differentiate into a variety of cells and their proliferation capacity is also unsurpassed by any other cell type. There are three major problems with ES cells; ethical issues, immunological rejection problems and the potential of developing teratomas.
In the future, ideally, somatic stem cells from the patient will be extracted and manipulated and then reintroduced into the same patient to cure debilitating diseases.

Stem Cell
Facts
What are stem cells?
Stem cells are the foundation cells for every organ and
tissue in our bodies. The highly specialized cells that make
up these tissues originally came from an initial pool of stem
cells formed shortly after fertilization. Throughout our lives,
we continue to rely on stem cells to replace injured tissues
and cells that are lost every day, such as those in our skin,
hair, blood and the lining of our gut. Stem cells have two
key properties: 1) the ability to self-renew, dividing in a
way that makes copies of themselves, and 2) the ability to
differentiate, giving rise to the mature types of cells that
make up our organs and tissues.
Tissue-specific stem cells
Tissue-specific stem cells, which are sometimes referred to
as “adult” or “somatic” stem cells, are already somewhat
specialized and can produce some or all of the mature
cell types found within the particular tissue or organ in
which they reside. Because of their ability to generate
multiple, organ-specific, cell types, they are described as
“multipotent.” For example, stem cells found within the
adult brain are capable of making neurons and two types of
glial cells, astrocytes and oligodendrocytes.
Tissue-specific stem cells have been found in several organs
that need to continuously replenish themselves, such as the
blood, skin and gut and have even been found in other, less
regenerative, organs such as the brain. These types of stem
cells represent a very small population and are often buried
deep within a given tissue, making them difficult to identify,
isolate and grow in a laboratory setting.

Embryonic stem cells
Embryonic stem cells have been derived from a variety
of species, including humans, and are described as
“pluripotent,” meaning that they can generate all the
different types of cells in the body. Embryonic stem cells
can be obtained from the blastocyst, a very early stage
of development that consists of a mostly hollow ball of
approximately 150-200 cells and is barely visible to the
naked eye. At this stage, there are no organs, not even
blood, just an “inner cell mass” from which embryonic stem
cells can be obtained. Human embryonic stem cells are
derived primarily from blastocysts that were created by
in vitro fertilization (IVF) for assisted reproduction but
were no longer needed.
The fertilized egg and the cells that immediately arise in the
first few divisions are “totipotent.” This means that, under
the right conditions, they can generate a viable embryo
(including support tissues such as the placenta). Within a
matter of days, however, these cells transition to become
pluripote ...
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Editor's Notes
In order to be used clinically, human embryonic stem cells must be differentiated prior to use in patients. Undifferentiated stem cells could produce tumors and multiply unchecked within a patient, causing more problems than providing appropriate therapy. It is uncertain if conditions can be defined such that all embryonic stem cells differentiate into the correct cell type prior to therapeutic use. Complications caused by undifferentiated cells might not be discovered until years after the first clinical trials are begun. This differentiation problem is acknowledged on the International Society for Stem Cell Research website: "Scientists are still working on developing proper conditions to differentiate embryonic stem cells into specialized cells. As embryonic stem cells grow very fast, scientists must be very careful in fully differentiating them into specialized cells. Otherwise, any remaining embryonic stem cells can grow uncontrolled and form tumors." 1 Recently, three established stem cell lines were shown to exhibit abnormalities in chromosome number and structure. 2 , 3 Obviously, stem cell lines must be checked periodically to make sure the cells do not become abnormal during continued culture. The use of abnormal cells in treatment of patients could result in indeterminate complications. References " Frequently Asked Questions ." International Society for Stem Cell Research. Draper, J.S., et al., "Recurrent gain of chromosomes 17q and 12 in cultured human embryonic stem cells," Nature Biotechnology December 7, 2003, advance online publication. C. Cowan et al. 2004.

Undifferentiated stem cells could produce tumors and multiply unchecked within a patient, causing more problems than providing appropriate therapy. According to a recent article ion the New England Journal of Medicine : "There are still many hurdles to clear before embryonic stem cells can be used therapeutically. For example, because undifferentiated embryonic stem cells can form tumors after transplantation in histocompatible animals, it is important to determine an appropriate state of differentiation before transplantation. Differentiation protocols for many cell types have yet to be established. Targeting the differentiated cells to the appropriate organ and the appropriate part of the organ is also a challenge.” Harvard scientists reported in the Proceedings of the National Academy of Sciences that five out of the 19 mice injected with embryonic stem cells developed tumors and died." 2 Stem cell lines will suffer the same tissue rejection problems as adult transplants. Once differentiated, these cells will express the HLA tissue antigens programmed by their parental DNA. These antigens must match those of the recipient or else tissue rejection will occur. An admission of the problem of immune rejection can be found from The Scientist : "[W]ithin the [embryonic stem cell] research community, realism has overtaken early euphoria as scientists realize the difficulty of harnessing ESCs safely and effectively for clinical applications. After earlier papers in 2000 and 2001 identified some possibilities, research continued to highlight the tasks that lie ahead in steering cell differentiation and avoiding side effects, such as immune rejection and tumorigenesis.” 1 References E.
