GENETICALLY ENGINEERED PROBIOTIC THAT TARGETS AND KILLS CANCER CELLS IN THE GUT

Image
Colorectal growth is the third most normal disease around the world, and its frequency is anticipated to ascend in the following couple of years. The investigation, which was coordinated by Dr. Chun-Loong Ho, has as of late been distributed in the diary Nature Biomedical Engineering.

The significant component of this disease focusing on a framework is a built type of E. coli Nissle; a safe type of microbe found in the gut.



The microscopic organisms were hereditarily designed into a probiotic that ties to the surface of colorectal growth cells and secrete a chemical to change over a substance found in cruciferous vegetables, for example, broccoli into an effective anticancer operator. The examination meant to execute growth cells in the gut by enabling them to take up this anticancer specialist. As ordinary cells can't do this change and are not influenced by the poison, the framework is relied upon to target just colorectal malignancy cells.

Over 95% of colorectal malignancy cells t…

Multiple electromagnetic responses from accordion-like plasmonic nanorods

Image
Well-defined complex nanostructures for metamaterials with unique optical properties – such as negative refractive index, strong artificial optical activity, and perfect absorption – are usually prepared by top-down approaches, including direct laser writing, multiple e-beam lithographies, and membrane projection lithography.

However, these methods have two critical drawbacks: 1) Large-scale device fabrication is practically impossible due to time and energy consuming process; and 2), the operating window is limited (not working in visible or UV regime) due to the large feature size of the structures.

In a recent breakthrough, scientists in Korea have combined block copolymer (BCP) self-assembly and an anodized aluminum oxide (AAO) template to fabricate unique complex nanostructures over a large (centimeter) area.



In this work, the scientists introduce a novel method to fabricate a high-density array of plasmonic nanorods over a large area (2.5cm x 2.5cm), exhibiting multiple electro…

Massive Study Clarifies Genetic Risks of Major Depression

Advance in hereditary methodologies is changing numerous regions of a drug, including psychiatry. While the hereditary qualities of schizophrenia have been most effectively considered, real depressive issue (MDD) is a weakening condition that influences a large number of individuals around the world, causing a monstrous toll of human enduring and monetary misfortune, as indicated by the World Health Organization (connect is outer). Similarly, as with mental conditions, all in all, the science of MDD is worked out to a restricted degree just, however that is evolving. Including the profound layer of hereditary examination to understanding the reasons for MDD, recognizing what qualities are influenced, and what they really do, will propel the aversion, conclusion and treatment of MDD, while likewise by and large extending our grip of how the mind attempts to offer ascent to our regular encounters in health and sickness.



Since MDD can introduce in such huge numbers of various courses, e…

NON- TOXIC ALTERNATIVE TO REPLACE LEAD-BASED SOLAR CELLS

Image
Recent research on energy has focused on a variety of novel energy devices and nanomaterials.The frontier energy research has produced such materials as nanocomposites for advanced electrochemical energy storage devices.

The vast majority of the solar based cells which we see covering fields and housetops are produced using silicon. In spite of the fact that silicon is highly proficient at changing light into energy, it has a low "defect resistance," implying that the silicon needs high amounts of purity, making it energy intensive to deliver.


In the course of recent years, specialists have been searching for materials which can perform at comparable or better levels to silicon, however that don't need such high purity levels, making them less expensive to produce. The most promising group of these new materials are called hybrid lead halide perovskites, which seem to guarantee a transformation in the field of solar energy.
Whether the lead contained inside perovskite s…

A few Conditions that may cause leukopenia

Image
What is leukopenia?
Leukopenia is a condition where a person has fewer white blood cells in their bloodstream than they should. Leukopenia is diagnosed with a blood test called a complete blood count or CBC. A healthy white blood cell count is between 3,500 and 11,000 white blood cells per microliter. A person with leukopenia may have fewer than 3,500 white blood cells per microliter. White blood cells are made in the bone marrow and are critical for the immune system. Having too few of them means the body is less able to fight off infections and diseases.

There are five types of white blood cells. Each helps to protect the body from a different kind of infection:
Neutrophils: These make up 55 to 70 percent of total white blood cells. They help fight off fungal and bacterial infections.Lymphocytes: These are the second most common type of white blood cell. They protect the body from viral infections.Basophils: These are the least common type of the white blood cells. They are involved …

Can a brain injury change who you are?

Image
Our identity and what makes "us" has been the subject of much open deliberation all through history. At the individual level, the elements for the interesting pith of a man comprise for the most part of identity ideas. Things like thoughtfulness, warmth, threatening vibe and childishness. More profound than this, notwithstanding, is the manner by which we respond to our general surroundings, react socially, our ethical thinking, and capacity to oversee feelings and practices.

Thinkers, including Plato and Descartes, credited these encounters to non-physical elements, very separate to the brain. "Souls", they depict, are the place human encounters happen. As indicated by this conviction, souls house our identities and empower moral thinking to happen. This thought still appreciates significant help today. Numerous are support for the possibility that the spirit does not require the cerebrum, and mental life can proceed after death.

In the event that our identity is…

Obesity and Malnutrition: Two Aspects of One Crisis

Image
Obesity is the medical condition in which the person is having excess body fat or considered as overweight. Approximately 30% of the population is believed to be overweight or obese. It is one of the major global issues faced in today’s world. With the strenuous daily schedule, people nowadays prefer fast food for themselves and their family. Fast food products have replaced home-made food at a massive rate. It tends to save the time which is required to cook the food. Moreover, the younger generation prefers junk food due to their appealing taste. Junk Food is the food items consisting of a high amount of calories, fat and carbohydrate and lower levels of protein, fiber, vitamin and minerals thus it contains high calories with low nutritious values which causes serious health problems.
Some of the major health issues faced due to the consumption of junk food are diabetes, obesity, cardiovascular problems which may further lead to chronic health problems. According to a study, 4 out o…

Metamaterial Optical Solar Reflectors (meta-OSRs) radiate IR heat and reflect most of the optical solar spectrum.

Tooth sensitivity with a desensitizing-containing at-home bleaching gel—a randomized triple-blind clinical trial

Desensitizing operators are generally incorporated into the piece of blanching specialists to lessen dying instigated tooth affectability (TS). This randomized clinical trial (RCT) assessed the hazard and power of TS and shading change after at-home dying with a desensitizing-containing (3% potassium nitrate and 0.2% sodium fluoride) and without desensitizing 10% carbamide peroxide (CP) gel (Whiteness Perfect, FGM).

Techniques:
A triple-daze, inside individual RCT was led on 60 without caries grown-up patients. Every member utilized the gel in a fading plate for 3 h day by day for 21 days in both the upper and lower dental curves. The supreme hazard and force of TS were evaluated day by day through the 0– 10 VAS and NRS scale for 21 days. Shading change was recorded utilizing shade guides (Vita Classical and Vita Bleached guide) and the Easy shade spectrophotometer at standard, week after week and 30 days after the finish of the dying. The hazard and force of TS were assessed by the M…

From Massive to Miniature: How Ultrasound Technology Has Changed Towards Portability & User-Friendly

Image
Ultrasound machines have traveled a long path after its invention. The introductory ultrasound machine was a 2-dimensional  scanner introduced in 1958 by Tom Brown and Ian Donald. They called it the Diasonograph, but it was well-known in more informal and unkind circles as the Dinosaurograph,


Fig. 1 Ian Donald operating the Mark 3 Diasonograph

This ascendant of the current day ultrasound device was 8 ft tall and occupied close to a third of the space available in an average scanning room. The ultrasound images were still and were formed by rocking the transducer slowly over the body part that needs to be examined. This was no small effort as the gantry that housed the probe was very large as well, and much physical exertion had to be utilized to alter the scanning plane. The image wholly lacked any greyscale, but it would still look eventually on a cathode ray tube. The Diasonograph’s first contribution to medicine and ultrasound technology is that it glint the ultrasound race.

Full Sized Beating Hearts Grown from Stem Cells!!

Image
About 4000 Americans waiting for heart transplants, only 2500 will receive new hearts in the next year. In those lucky 2500, the biggest risk is their body will reject the new heart and launch a massive immune reaction against the foreign cells. To overcome the problems of organ shortage and to reduce the chance of patient’s body rejecting it, researchers were working to create synthetic organs from patients own cells.

Ideally, scientists would be able to grow working hearts from patients own tissues, but they are not quite there yet. That’s because organs have a particular architecture. It’s easier to grow them in lab if they have a scaffolding on which the cells can build, like building a house with the frame already constructed.

In their previous work, the scientists created a technique in which they use a detergent solution to strip a donor organ of cells that might set off an immune response in the recipient. They did that in mouse hearts, but for this study, the researchers use…

Know what you are eating: Food or Adulterants?

Image
Food adulteration is the process in which the food quality standard is degraded the addition of low-quality components or by the extraction of valuable ingredient or nutrients. The intentional addition or alteration of the ingredients and the biological and chemical contamination during the process of production, storage, processing, transport and distribution of the food products are responsible for the lowering or degradation of the quality of food products and are considered as adulterationAdulterants are those substances which are added during the processing of the food products and are unsafe for human consumption.

Under the food laws and acts by the legislative bodies. any food product with lowered or degraded quality standards are defined as Adulterated Food but under the new law (FSS Act, 2006), the word adulterated food has been coined as Substandard, Unsafe or Food consisting of extraneous substances.

A food product is considered as adulterated if:

An ingredient which is i…

Wound Management: Surgical site infections (SSIs)

Image
Surgical site infections (SSIs) are the foremost and frequent complications in surgery procedures, with the documented incidence in literature starting from 3% to 30%. Patient-specific risk factors are the foremost challenging to manage. By addressing the determined SSI rate as a function of eight specific “risk points” to manage among the operative method (preoperative, intraoperative, postoperative, discharge), the reduction in SSI incidence will be achieved. Addressing the Risk Points 1. Modifiable / Nonmodifiable Risk Factors · Non-modifiable risk factors: advanced age, pre-existing conditions such as cancer, past medical interventions (e.g., radiation), and personal history/propensity for actual infection. · Modifiable risk factors: diabetes mellitus (short-term normalization of blood glucose values is more important than control of HgB A1c), obesity, alcohol abuse, tobacco abuse (current or history of), serum albumin (below 3.5 mg/dL: normal 3.5–5.0 mg/dL), serum bilirubin (total: be…

PROBIOTICS IN NUTRITION ADVANCEMENT

As researchers find more about probiotics, it shows up these infinitesimal microscopic organisms might be instrumental to the treatment and counteractive action of certain irresistible ailments, metabolic conditions, invulnerable disarranges and neurological issue.

Probiotics are live, dynamic microorganisms ingested to adjust the gastrointestinal vegetation for medical advantages. They frequently are alluded to as "great" microscopic organisms in the gut and contend with "terrible" microbes for bond destinations to either freed the collection of pathogens or increment the host's resistant framework. Their advantages were first seen hundreds of years prior, when individuals began eating matured nutrition. Today, those nourishments incorporate matured vegetables, sauerkraut, miso, aged cheddar, kefir, yogurt, tempeh, pickles, kimchi, green olives, wine, natto and sourdough bread. Notwithstanding aged nourishments, probiotic supplements are accessible in pill, p…

Graphene to Disrupt Biofilms on Dental Implants

Image
Graphenethe basic structural element of allotropes of carbon, such as graphite, charcoal, carbon nanotubes andfullerenes. It is also the major research topic in the arena of Materials Science and Engineering, Nanomaterials. Scientists established that the layer of graphene can form a protective film on the surface of implants that can prevent bacterial infection. Systems, for example, dental implant or knee substitution surgery always carries a danger of bacterial infection. Microorganisms that enter the body circulate in liquids, such as, the blood, and discover surfaces to stick to. Once joined, they multiply to frame a protective "biofilm" that can once in a while, stop an implant appending to bone.

As revealed in the journal Advanced Materials Interfaces, analysts at Chalmers could show that a layer of vertical graphene chips can frame a defensive layer over the surface of the implant, hindering bacterial attachment. The sharp graphene flakes cut the microscopic organisms …

Blood stem cells study could pave the way for new cancer therapy.

Individuals with leukemia would benefit from outside intervention by new research that reveals insight into how the body creates its blood supply. Researchers are a bit nearer to making blood undifferentiated cells that could lessen the requirement for bone marrow transplants in patients with growth or blood issue. Empowering researchers to develop the foundational microorganisms falsely from pluripotent undifferentiated cells could likewise prompt the improvement of customized blood treatments, scientists say. Blood immature microorganisms are found in bone marrow and create all platelets in the body. These cells - known as hematopoietic foundational microorganisms (HSCs) - help to re-establish blood supply in patients who have been dealt with for leukemia. Researchers utilized a mouse model to pinpoint precisely how HSCs create in the womb. They appeared out of the blue how three key particles cooperate together to produce the cells, which are later found in grown-up bone marrow. T…
