Human whole genome sequencing, experts said that quick and simple sequencing method, will effectively promotes the clinical field of cancer and genetic diseases diagnosis technology, and brings new clues for food safety gene detection. 

When pathogenic bacteria cause infectious diseases, preventive medicine workers will face the following important questions: 1. Where are the pathogenic bacteria from? What may be the transmission route? 2. What survival ability, virulence and drug resistance characteristics do pathogens have? 3. What routines are pathogenic causes of disease? High throughput sequencing technology and the rapid development of information technology provide a new idea and solution for the above problems.

Merry Christmas to all!

What Are Knockout Mice

What are knockout mice? Is it typically alluded to the research facility white mice? Indeed, mice have numerous sorts, and the white mice is only one sort of those. Typically the ordinary white mice are pharmaceutical utilized for clinical trials, while the knockout gene mice are for more complex biomedical exploration.

Quality knockout mice: in the mouse embryonic undeveloped cells by the method for quality alteration, we change the objective quality, and after that embed the "adjusted" embryonic undifferentiated organisms into the early fetuses to frame allophenic mice. At the point when the allophenic mice grow up, the "altered" quality and the quality that has not been adjusted exist in the body in the same time. In the event that the germ cells of a few mice have been "altered", the mice will bring forth a transgenic mice. (what are transgenic mice?)

Quality knockout utilizing quality homologous recombination:

Quality knockout was produced in 80's with the utilization of DNA homologous recombination standard. In the mid 80's, the segregation and society of embryonic stem (ES) cells in vitro had established a framework for the gene knockout. Quality knockout is still the most widely recognized strategy for developing quality knockout animals model.

Impelled quality knockout is additionally taking into account Cre/loxp framework, yet it can control Cre expression and Cre quality expression framework keeping in mind the end goal to control the time, and to accomplish the objective of hereditary alteration of particular qualities in 1oxP creatures. It can be utilized to control Cre expression.

"knockout mice" itself is an extremely spearheading strategy in the biomedical field, and due to the comparability in the middle of human and mouse qualities, it is conceivable to have the potential for the investigation of human hereditary maladies, for example, coronary illness, diabetes et cetera.

Quality knockout innovation is principally utilized as a part of the foundation of creature model, and the most develop test creatures are mice. The quality knockout model for expansive warm blooded animals is still at the exploratory stage.

What are transgenic mice?

What are transgenic mice?

The exogenous recombinant genes are transfected into the genome of the animal receptor, and the genes can be expressed in vivo of the animals. Transgenic animal expression system includes exogenous gene, expression vector and receptor cell. the transfer of genome are nuclear transplantation and animal cloning technology. Artificial synthesis, design of genes and genome of the transgenic technology belong to synthetic biology.

In 1974, Rudolf Jaenisch created the first mouse to carry exogenous genes by injecting DNA of SV40 virus into the blastocyst of mice. Later, researchers injected the Murine leukemia virus into the mouse embryos, which were stably inherited in the mice, and the exogenous genes could be stably expressed in the offspring. These mice that are genetic stably and can express exogenous genes are that we call transgenic mice now in general.

What are transgenic animals model?

For ordinary transgenic genes, the expression region will depend on the promoter. If we choose the promoter expressing the whole body, like Rosa26, CAG, etc, the whole body-expressed transgenic mice can be produced. If the promoter of a number of tissue-specific genes is chosen, we will gain transgenic mice expressing the specific tissue. For example, under the role of AP2 promoter, the transgenic mice with specific expression of adipose tissue will be gained.

It should be noted that this strategy is to inject the gene fragment directly into the zygote of mice. The transgenic fragment will be randomly inserted into the mouse genome. Because it is completely random, it may be inserted into some of the inhibition zone leading to the gene transfer, but also it may be inserted into some of the enhanced zone leading to the gene high-expression. The first generation of transgenic mice are called founder. Because of the randomness, each founder is not the same. Each founder’s original species is called line. The expression of different lines may be different.

Doctorate of Japanese female scientist Obo Kataharuko is officially canceled

Japan's Waseda University reported the official cancelation of Obo Kataharuko's doctoral degree on November second. Waseda University a year prior found that Obo Kataharuko's doctoral suggestion had the issue of picture misappropriation, and asked for that modify in one year and re-submitted papers according to the academic standards. Yet, the last certification of the Waseda University demanded that Obo Kataharuko's adjusted papers fail to meet the necessities of the study, so her doctoral degree was scratched off formally.

Obo Kataharuko had requested to widen the terms from the modification, yet which was rejected by the Waseda University for whole deal impermanent hold issue of paper. Obo Kataharuko, who proceeded onward from Waseda University in 2011, got a doctorate from the University.

Obo Kataharuko circulated papers on the United Kingdom "nature" magazine in mid 2014, ensuring that the viable advancement of another "comprehensive cell" - "STAP cells", scrounging up a buzz in the exploratory world. Regardless, soon, reiterated test's examination gathering pointed out that there were various inquiries in her paper. After an intensive examination, Japan's Institute of science and science reported that the paper is "produced" and "modifying" in April 2014, and in September this year proclaimed that the assumed new comprehensive cell was truly gotten from the security of embryonic undifferentiated life forms.

This academic deception event is clearing. Obo Kataharuko herself surrendered from the Institute of Japanese science and science. Event included American scientist Charles·Vacanti furthermore surrendered from the Harvard joined forces mending office. The more unmistakable calamity is that Obo Kataharuko's aide I Yoshiki presented suicide.

Large Scale Data Analysis Tells You That Whether There Is Gender Difference in the Brain Or Not

What is the qualification amidst male and female brains? This issue is not only a fascinating issue which has long been talked about, furthermore a living job dramatization club relies on upon. In any case, a late study exhibits that there is no obvious qualification amidst men and women's brains. (In fact, even thought related study has not be done on the animal model of disease.)
The study, drove by Lise Eliot at Franklin Rosalind Medical University, found that the hippocampi in the cerebrum of men and women was thought to be a bit of the memory control and feeling control and had no refinements in volume.
Data from this study were performed on cerebrum alluring resonation imaging by 6000 people (It is said such investigation will be driven on the transgenic mice in later future). By researching and numbering the results, the investigators found that hippocampi in men and women's brains were practically identical in size.
It has long been trusted that "sex contrasts" in the brain is the essential driver of "sex differences" in character, and this declaration is across the board. Regardless, we accumulated a considerable measure of data, and show that the affirmed "reason" is in every practical sense non-existent or to a great degree weak.
The hippocampus is a region of the brain responsible for temporary and whole deal memory and the relationship amidst feelings and resources. Before it was seen as that the volume of the hippocampus of the female was more vital than that of men, which further assumed that women were more eager than men, and more fragile to the memory of the word than men.
The study was finished to survey other related asks about. The corpus callosum, which is related between the left and right sides of the cerebrum, was generally considered to have volume complexities between the sexual orientations. It even once has be felt that men and women have a sensible difference in the planning of tongue. On the other hand, the tremendous scale data examination has denied the above announcement.
"Various people feel that there are the gathered" male personality " and " the female cerebrum "thoughts. In any case, through considerable scale data examination, you will find that these refinements are altogether little ".

A New Way to Starve Cancer Cells

Lung cancer is a malignant tumor that seriously endangers human health, and it is one of the highest incidence and mortality rate cancer in the world. A new study, published in the Journal Molecular Cell on October 15th, opened a new way for lung cancer treatment. Studies showed that preventing the use of alternative sources of nutrition can stop the growth of lung cancer cells.
What to eat of cancer cells?
The metabolism of cancer cells is very different from that of normal cells. The rapidly proliferating cancer cells have a very high demand for energy, and they will take the main source of glucose. Cancer cells use glucose faster than normal cells 10 times or even hundreds of times. When glucose is destitute , cancer cells need to use other nutrients to maintain their growth and survival.
Scientists at the University of McGill, Washington, ITMO and Bristol have conducted a thorough study of non small cell lung cancer. They found that in the case of glucose deprivation, lung cancer cells will change their eating habits, liking using glutamine. This is an important metabolic mechanism for cancer cell growth.
The researchers point out that lung cancer cells metabolize through the PEPCK enzyme. "In the past, people mainly study PEPCK in the specialized tissues of glucose production, such as the liver," Emma Vincent of McGill University said. "In fact, some cancer cells also express PEPCK, which allows the cancer cells to use glutamine to support their growth. PEPCK is a kind of important metabolic switch, which helps cancer cells to survive and proliferate under the condition of starvation." The study shows that the PEPCK in the tumor cells can delay the growth of tumor in transgenic mice.
For a taste
The researchers also find that PEPCK levels are elevated in the tissues of patients with lung cancer. "This shows that PEPCK plays an important role in human disease (Alzheimer's Disease Models) ," said Russell Jones, an associate professor at McGill University. "The availability of nutrition can affect the development of cancer." Cancer cells will use alternative energy sources under pressure, which can lead fatal death. To understand the specific mechanisms behind this process will bring new hope for cancer treatment.

The Largest Clinical Trials in the History of the UK to Participate in Cancer Testing

According to foreign media reports, the United Kingdom will start the world's largest clinical trial toxicity test of the aspirin efficacy. About 11,000 people who have early colorectal cancer, breast cancer, prostate cancer, gastric cancer and esophageal cancer will be involved in this experiment.
In the last few years, the debate over whether aspirin has an effect on cancer has become more intense because of its uncertainty. Scientists say that if the effect of the drug on disease model is to be confirmed, it will bring revolutionary changes to provide a cheap and effective treatment for cancer patients.
The clinical trial is jointly funded by the UK charity Cancer Research Center and the National Institutes of health, and the patients will take an aspirin every day for 5 years. The researchers will compared patients with different doses who are treated with false drugs (placebo) to examine whether the cancer has a recurrence.
"This clinical trial is particularly exciting because cancer recurrence is often difficult to cure, so finding a cheap and effective way of fighting cancer is likely to bring a revolutionary change to the sick," says Dr. Fiona Reddington of the UK cancer research center.
This clinical trial will be conducted in the UK's 100 medical institutions. Many patients and some who have been cured of early cancers will be involved. This experiment will continue for 12 years. Taking drugs every day also brings a series of health problems, because it may bring side effects, such as stomach ulcers and stomach bleeding, etc..
"There have been some interesting studies that have shown that aspirin can delay or prevent the recurrence of early cancers," says Ruth Langley, the lead researcher at the experiment. The purpose of this experiment is to solve the problem.
"If our study shows that aspirin does prevent cancer, it can completely change the future treatment and provide a simple and inexpensive way to prevent cancer from recurring," Ruth said."
Alex King was diagnosed with breast cancer in December 2009 with age of 51, and has now been cured. He said: "cancer is the worst of my life experience and anything which can reduce the chance of cancer recurrence is very important." Many people now take a small dose of aspirin as a kind of heart disease drugs every day.

Instruction Manual, Can You Read?

They have a frail limit of absorption framework, so should take a little dose.
As demonstrated by a survey, the falls have transformed into the first adversary of the elderly over 65 years old in China of damage passings, and more investigates presentation taking blood, antidiabetic drugs, antipsychotic drugs, diuresis solutions and analgesics will extend the threat of falls.

For growing the risk of falls in the elderly, Professor Lu Yu says that the occasion of falls is related to medication time and estimation, in light of the way that the old man's ability to assimilation framework is decently weak.
"In the pharmaceutical manual, it will show particular people's metabolic data." Lu Yu says. Investigation shows up, taking high estimations of central tangible framework drugs of elderly people will no ifs ands or buts assemble the peril of falling. It generally takes sways in thirty minutes, and after the effects, patients may fall when they get up or go to restroom.

Lu Yu suggested that prescription use in the elderly needs an unmistakable sign. Each one of the prescriptions can realize falling should have toxicity tests. Major solutions are diminished the using estimation entirely far. Should be started from estimation association, close discernment.

What is the which method for contraindications and unfavorable reactions? 

Contraindications patients ought not take remedy. Hostile reactions may not happen.

"There will be a couple of equal words taking drugs rules. Individuals as a rule should moreover appreciate about these matters." Lu Yu took an example, "contraindications" and "disagreeable effects" on rules are critical. both of which have assorted perception.

In case your case fits in with a "contraindications", so you mustn't take drugs. "Unfavorable effects" is used to the reaction after medication, however not as is normally done to appear on the customers. It just reminds the patients legitimately before taking pills, in the occasion of threatening reactions without help.

Likewise, there are fundamental used things like unlawful, refrain from using and RY. From the perilous degree, unlawful has a bigger number of genuine risk than that of swear off using, refuse using more conspicuous than RY. All things considered, RY is that in the wake of taking prescription, if there are hostile reactions viewed. Stopped taking if yes and continue if no.

"Keep away from using", that is to say, not to use. It may appears to be apparent disagreeable reactions and unfavorable results taking meds by patients. Regardless, there are particular differentiations, we can not whole up. So this word is used to alert.

"Precluded" suggests that there is no space to pick. It will have certifiable unfavorable reactions or hurting if such medicine is manhandled.

Primates Like Cradlesong the Same as Human Infants

As everybody knows, for people, everyone likes music and feel the music bliss going on. In any case, specialists discovered beginning late creatures are also playing a little music from fish to monkeys to welcome the life favorable. 

Music inclinations of creatures may be identified with the prompting of music. 

As appeared by a study scattered by diary information appears, through primates creature acknowledgment to music inclinations of focal and south American monkeys, the scientists find non-human primate animals appear to slant toward fundamental kids' tunes to fast pace moving tunes. 

Josh Mcdermott from Massachusetts Institute of advancement and his accomplice Mark House from Harvard University put the a horn close to the supporting of the branches. Right when there is little monkey own colliding with the branch, the analysts will make the horn discharge some music. 

In different tests, masters played the Russian people rest time tunes with woodwinds, Mozart's Concerto in B level major k458, Germany cradlesong, and Alec Empel' solid tune "no getaway from component". 

In the emphasized tests, the monkeys were gathered in the branches of the most direct music. The music was all things considered a hypnotizing. Mader Mott said that the music inclinations of creatures may be identified with the some affectation of the music. He cleared up: "in like way edgy environment occasions like battling and tornadoes, when in doubt there was an enthusiastic voice. Monkeys and unmistakable creatures in this way passed on an impelled reaction to the savage occasions on sound. Straightforward course stable means the circumstance is frightful." 

The monkey felt that the lively cadence of the music is nervous, yet different individuals simply revered the solid slant, which was clearly the weekend's tune to enter the top. Assorted studies by Mader Mott demonstrated that human infant youngsters are really like primates, as to listen to the music. It might be a side eagerness for grown-ups to recognize solid music.

The PK Studies of the Patients

On occasion we use the practical and theoretical schedules to judge whether the individual or the patient or the volunteer is met all necessities for a certain exploratory study. Regardless, as a general rule, in the first run through of the prescription headway, we have consistent PK data accumulated from the patients to upgrade the results. It is so urgent to judge whether the volunteer is suitable for the treatment. From the United States FDA, with a particular deciding objective to see the medicine obsession time profiles, it is discriminating to explore about PK study. 

To focus on PK 

Now and again, various people or patients have particular exercises towards the drugs. The key inspiration to ponder PK is do arranged examination to those particular patients. 

There are a couple of outlines with PK considers: 

PK examinations of patients with insufficient renal limit; 

PK examinations of patients with insufficient liver limit; 

PK looks at with lacking overpowering patients; 

PK considers in poor fields and broadly; 

PK examinations of patients in youths; 

PK examinations of patients with the elderly. 

We can do PK considers in various people with unmistakable prescriptions, which can achieve through the PK data and some other joining data like smoking status, age, sexual introduction, body weight, renal limit, disease status,genetic or genomics data. 

The delineations are according to the accompanying: 

PK examinations of patients with torment after operation; 

PK examinations of patients with rheumatoid joint irritation; 

PK examinations of patients with sort 2 diabetes; 

PK examinations of patients with arrhythmias. 

Finally, the third inspiration to do PK study with the patient is that the drug test goes to the first period starting now, when the hostile event profile of the substance and/or its metabolites passes on unnecessarily certifiable a threat, making it difficult to legitimize controlling it to sound volunteers. Those studies are doing in the patients' body and they are used to treat. 

These are a couple tests: 

PK examinations of oncology patients with cytostatics; 

PK examinations of heart transplant patients with immunomodulators; 

PK examinations of schizophrenic patients with antipsychotics. 

The date can be get by expansive blood testing or sparse reviewing.

What the Nature Tell Us!

I went to the Natural History Museum starting late. The display lobby looks like a goliath Nautilus, which is apportioned into 5 layers. The recorded focus shows are extraordinarily rich. There are more than ten thousand bits of samples from the seven territories: a sweeping number of phenomenal fossils and profitable metals, moreover is furnished with numerous visual media, four-dimensional silver screen and other propelled equipment. These cases and fossils let us cross time and space, extend our perspectives, pass on us to the old times. 

On the knolls of Africa Pavilion, there were a photograph with animal models. There were mandrills, puma and crocodile... The animals' life in the African prairies was obviously outlined. The mouthpiece reenacted a blended pack of animal sounds, so we gave off an impression of being on the scene. 

In the entryway and the B1 layer, different antiquated fossils were shown. Also, I feel most captivated by Mamenchisaurus fossils. It is a herbivorous dinosaur with capricious shape, stalwart body, long neck and a watched strong tail. It is said that minimal avaricious dinosaurs couldn't stay away from the "tail". 

For the purpose behind the disposal of dinosaurs, some say that it is a result of a space rock pummeling into earth, and reasons a movement of environmental changes; some say that as a terrain's aftereffect plate skim, the air out of the blue gets the chance to be frigid; and moreover the volcanic launches, so that the earth has been able to be hot, and the dinosaur eggs are cooked... There may be some truth in these conflicts, notwithstanding I think it is certain that the destruction of dinosaurs has relationship with nature depravation. This may moreover be the explanation behind the obliteration of various other antiquated animals! 

In this way, I consider people. Whether the general population have a day like that? Nature tells us that any living things will encounter the methodology of initiation, change and end. As a specie, individuals need to experience this methodology. Fortunately, individuals are in a matter of seconds stirring, seeing the hugeness of guaranteeing the regular habitat, propelling the efforts to establish safety, building organic advancement. We also need to start from ourselves to guarantee the little's way watches.

Brain Science

How huge the universe is, the way vast the mind is. Notwithstanding the obscure zone of the cerebrum, the supposed "mind researchers" and "the laymen" have the relationship like the "Fifty stage" and the "one hundred stage". The most serious issue is to know yourself.

"Ten years of the mind" program. U.S. President Barack Bush marked a record that the most recent ten years in twentieth Century (1990-1999) was named as the "mind ten years". The assignment is to think about the Neural Genetics, neural capacity recuperation, memory misfortune and memory issue, concentrating on assurance of cerebrum, counteractive action and treatment of mind ailment to enhance the comprehension of the cerebrum, furthermore make leap forward on the avoidance and treatment of neurological maladies, for example, Parkinson's ailment (PD), AD, dejection, schizophrenia, and so forth..
New "mind venture". Taking after the April 7, in 2013, the United States formally reported the arrangement. The arrangement's name is "imaginative, front line mind neural innovation". The objective is to cerebrum action to draw the guide. Obama in the White House declared arrangements to caution the partaking researchers that the system could make employments, and may enhance the lives of billions of individuals around the globe. He likewise cautioned the United States not to miss the open door, or the following one to make new work opportunities would likely happen in China, India or germany.

The U.S. Barrier Advanced Research Projects Agency additionally declared that it would put $70,000,000 in the following 5 years, supporting the improvement of therapeutic gadgets for the treatment of neurological issue and memory misfortune. White House authorities likewise urged researchers to intensely set forward "more eager objectives", in light of the fact that it is a long procedure to examine from the organic product fly, mice, puppies and after that people. The current infection patients have lost the tolerance to hold up.

Along these lines, the cerebrum science project includes the "human mind exploration and fundamental animal models of synchronous examination" content. The venture grows to the cerebrum illness mediation. Truth be told, American mind venture usage has been quickened, and attempt to "seize" high cerebrum framework!

Conditional Knockout and Recombinant Cre/loxP, Flp/FRT System

To do this experiment, I have checked some conditional gene knockout, Cre / loxP and FLP / frt recombination system materials and make a summary.

Classical gene knockout is sometimes unable to give birth due to the effects of the gene on the development of the embryo, or the experimental animals die of severe physiological defects after birth, or the animals can not produce offspring to obtain a homozygous animal model. These can be avoided through conditional gene knock-out or knock in. That is to say, in specific cells or tissues and specific cell development stages a particular gene is knocked in. It has important significance to study the features of specific gene in specific organization.

Currently Cre/loxP and Flp/FRT restructuring system is wildly used.

Cre / LoxP and Flp - LRT system derived from yeast can be used to study the phenotype of target gene inactivation in specific tissues and organs. Through the conventional gene targeting, equipping two loxP aligned in the same direction in the genomic target sites and mounting loxP floxed produced by ES cells. Then making the loxP floxed mice and CRE transgenic mice hybridize to produce modified conditional mutant mice. In the "floxed loxP" mice, although the target gene has been loaded on both sides of a loxP, but the target gene has not changed. So the "floxed 1oxP" mouse phenotype is still the same as the wild type’s. But when it crosses with Cre transgenic mice, the offspring will have "floxed loxP" target gene and Cre gene. The Cre gene expresses to produce Cre recombinant which can mediate the 1oxP of the target gene, cut a loxP and a target gene. Thus, the modification of the target gene is based on the expression of Cre. The expression characteristic of Cre determines the modification of target gene. That means which cells the Cre choose to express, where the modification of target gene will happen. The expression level of Cre will affect the efficiency of target gene in the cells. So as long as the expression specificity and the expression level can be controlled, it is possible to achieve the specificity and extent of target gene modification in mice.

Propose Environmental "Foundational microorganism Toxicology"

Marks: basic toxicology, foundational microorganism science, undeveloped cell toxicology, animal models 

Virtuoso Francescofaiola examination get-together joined trademark toxicology with undifferentiated living thing science to put forwart the "undeveloped cell toxicology" which is focusing on the regular contamination amazing for the world. 

More specialists have gotten a handle on that the establishment of a beneficial and inducing framework for the wide toxicological examination of human wellbeing is energetic drawing nearer. Yet, the standard studies rely on upon animal models. In spite of the way that the procedure has extended bewildering ground as of late, however the toxicological examination still goes up against distinctive issues, for case, the high cost, drawn out and animal ethics dialog. 

Isolated and the detainments of the typical in vitro toxicology explores, the usage of undeveloped cell change in the field of toxicology has brought new bits of knowledge and purposes of relaxation action. Vigorous microorganisms are more tricky to the surprising hurtfulness of harmful substances than the ordinary cells. The bizarre phenotypes of the sullyings can be used to reproduce the right on time times of human embryonic change, and can be used to utilitarian examination of diverse sorts. 

The undeveloped cell toxicology similarly gives an examination system which is not subject to animal tests. It can complete an expansive blended pack of malevolence appraisal, including exceptional hazardous quality, hatchling lethality, developmental threat, organ destructive quality, regenerative toxic quality and down to business unsafe quality examination. In the meantime, it can evidently seclude and evaluate the effect of human wellbeing. The essential results are depended on to give a convincing exploratory reference to the unmistakable confirmation, exchange and relationship of standard taintings.
