A new story from Inverse with a quote I gave: https://www.inverse.com/article/11766-how-instant-translatio…nd-listens #future

People can save lives when they speak the same language.

Technology has advanced such that we can instantaneously communicate with people in the farthest reaches of the world without breaking a sweat. Furthermore, we can do so in their own languages without even a single credit hour of exploratory language class. When language tools like Google Translate and Yandex. Translate meet communication apps like Skype and Telegram, the world shrinks in the best way.

Dan Simonson, a computational linguist and Ph.D. candidate at Georgetown University, endorses such language technology as a force for good, and it’s not just because he recently had to find the bathroom while visiting Beijing as a novice Mandarin speaker. “Humanitarian relief efforts are often executed by enlisted soldiers who have neither the time nor the resources to learn the language of where they are assigned to provide relief,” he says. “For these people to have access to even poor translation tools in low-resource languages — ones for which there isn’t a lot of data available to create translation tools — could immediately improve the efficiency of such relief efforts, saving thousands of lives as a result.”

3D printed bridge in Spain. Could this some day be our answer to reducing costs around US state and county infrastructure costs related to bridges and other structural repairs related to infrastructure?

The pedestrian crossing 3D-printed bridge installed in the urban park of Castilla La Mancha in Madrid, Spain, back in December is now ready to be used.

The 39-foot-long bridge was printed in micro-reinforced concrete at the Institute for Advanced Architecture of Catalonia.

In addition to the 3D printing, the production process was also environmentally friendly allowing the team to optimize the distribution of materials, minimize the amount of water, and recycle the raw material during manufacture.

Testing treatments for bone cancer tumors may get easier with new enhancements to sophisticated support structures that mimic their biological environment, according to Rice University scientists.

A team led by Rice bioengineer Antonios Mikos has enhanced its three-dimensional printed scaffold to see how Ewing’s sarcoma (bone cancer) cells respond to stimuli, especially shear stress, the force experienced by tumors as viscous fluid such as blood flows through bone. The researchers determined the structure of a scaffold, natural or not, has a very real effect on how cells express signaling proteins that help cancer grow.

Sarcoma Cells on a scaffold

Sarcoma (bone cancer) cells proliferate on the surface of a 3D printed scaffold created at Rice University. Experiments at Rice showed that the size of pores in the scaffold, which mimics the extracellular matrix in bone, and the pores’ orientation make a difference in how cells proliferate in the presence of a flowing fluid, like blood.

SWARM still only restricts itself to sample sets/ group representation of the population. And, when we place AI in this mix; I get concerned still where daily lives are impacted by decisions coming out from this model. For example, I would hate to see laws and policies rely on SWARM data reasoning as Laws and Policies often have special exceptions that Judges and Policy makers must still have the ability to call not AI with SWARM.

US intelligence is investing millions of dollars in a global research effort to boost analytical thinking by unlocking the reason in crowds.

Interesting read on recent Gastric Cancer research. I do a lot of work with the National Esophageal Cancer (EC) Awareness Association; I can tell you that this disease is truly a killer as gastric related cancers are horrible to detect early enough and have a horrible record of reoccurring. Survival rates are some of the worst and today the rates of EC have skyrocketed especially in the younger age groups such as 25 to 35 year olds.

When you work for these foundations, read the stories from patients and their families looking for answers and help with everything from help on what types of food can their love eat and hopefully keep down for nutrition, to how can they get help with transportation to simply go to work or the doctor as meds restrictions on driving, to knowing the end is near and how to prepare, etc. The worst ones are the 27 to 36 yr old fathers and mothers whose love one is saying good bye to the person they married only recently married the year before or spent 7 years with. This is why I work for my foundations as every small step does in the end create a larger impact in the end and hopefully helps us finally beat this disease.

STING (stimulator of interferon genes) has recently been found to play an important role in host defenses against virus and intracellular bacteria via the regulation of type-I IFN signaling and innate immunity. Chronic infection with Helicobacter pylori is identified as the strongest risk factor for gastric cancer. Thus, we aim to explore the function of STING signaling in the development of gastric cancer. Immunohistochemistry was used to detect STING expression in 217 gastric cancer patients who underwent surgical resection. STING protein expression was remarkably decreased in tumor tissues compared to non-tumor tissues, and low STING staining intensity was positively correlated with tumor size, tumor invasion depth, lymph mode metastasis, TNM stage, and reduced patients’ survival. Multivariate analysis identified STING as an independent prognostic factor, which could improve the predictive accuracy for overall survival when incorporated into TNM staging system. In vitro studies revealed that knock-down of STING promoted colony formation, viability, migration and invasion of gastric cancer cells, and also led to a defect in cytosolic DNA sensing. Besides, chronic H. pylori infection up-regulated STING expression and activated STING signaling in mice. In conclusion, STING was proposed as a novel independent prognostic factor and potential immunotherapeutic target for gastric cancer.

Need to share this with a few folks researching glaucoma disease and treatment/ mutation reversal.

Elderly are frequently hospitalized due to their age-associated organ degeneration, the presence of co-morbidities, and their susceptibility to adverse insults. Alterations in functional status often occur during hospitalization, and the degree of functional decline can parallel the severity of illnesses. For older persons, gauging their pre-morbid and in-hospital functional status facilitates treatment planning and potentially functional restoration1,2,3. While the identification of risk factors or markers of poor pre-morbid and in-hospital functional status may help facilitate this process, this area remains under-researched to date. Factors associated with functional decline in the hospitalized elderly include the types of morbidities and the reasons for their admission. Indeed, elderly with chronic kidney disease (CKD) are more likely to exhibit functional decline, beginning from the earlier stage of CKD to end-stage renal disease (ESRD)4,5; functional dependency also predisposes individuals with CKD and ESRD to recurrent hospitalization and higher mortality.

Albuminuria and proteinuria, as the staging criteria for CKD in the most recent version of Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines, are both well-established predictors of subsequent renal function decline. There is increasing awareness that albuminuria and proteinuria have an independent role in the prediction of adverse outcomes apart from the baseline renal function. As explained above, although CKD is associated with poor functional status, it is still unclear whether proteinuria alone exhibits similar association with functional status regardless of CKD. No reports focus on this association using the severity of proteinuria among geriatric patients with acute medical illnesses.

We hypothesized that elderly with proteinuria on admission, regardless of the presence of CKD, are more likely to have poor functional status, and that a dose-responsive relationship between the severity of proteinuria and that of functional impairment exists. Therefore, we conducted a cross-sectional study to evaluate this theory.

Latest study on chronic kidney disease (CKD) as it relates to the elderly patients and the relationship to the elderly’s organ decline over time. I can most certainly attest that I have seen many patients in their final days/ hours seeing their kidneys shutdown as a final state of life. Key is hopefully what doctors find in this research will enable us to prevent kidney failure or even improve the synbio kidney product that is being experimented on today for dialysis patients who badly need transplants and have a hard time finding donors.

This is definitely a share that is interesting to many studying synthetic organs and their acceptance into the human body as well as the work occurring on Quantum biology as well.

The goal of in vitro and in vivo toxicity testing is to identify compounds that would predict adverse reactions in humans. Olson et al. found that only 70% of human toxicity was predicted from animal testing. Currently we rely on traditional toxicity testing in animals, a 1930’s methodology that is now challenged due to questionable relevance to human risk, high cost, ethical concerns, and throughput that is too limited for the nearly 80,000 industrial chemicals not yet tested for safety. Additionally, testing usually extrapolates acute, high dose animal results to chronic, low dose human exposures, thereby risking rejection or limiting the use of drugs, industrial chemicals or consumer products. Moreover, the ability of lab animal target organ toxicity to predict dose-limiting toxicity in the corresponding human organ varies widely, from a low of 30% for human cutaneous toxicity, to 50–60% for human hepatotoxicity, to a high of 90% for hematological drug toxicity. Animal drug efficacy models are also notoriously discordant. In an analysis of six drugs to treat head injury, hemorrhage, acute ischemic stroke, neonatal respiratory distress syndrome, and osteoporosis, it was found that efficacy was similar in animals and humans for three drugs but was dissimilar for another three. In oncology drug development, animal models often over-predict anti-tumor efficacy in humans3,4. Examples such as these highlight the need to continue research into methods that reduce the dependence on laboratory animals for toxicity testing of environmental chemicals, determine efficacy and toxicity in drug development, serve as a mimic of human diseases, and provide patient-specific guidance in the emerging field of precision medicine.

Recent advances in bioengineered materials, microfluidic technology, and the availability of human primary, immortalized, and induced pluripotent stem cell (iPSC)-derived cells are enabling development of human microphysiological systems (MPS), sometimes called “organs-on-a-chip” or “human-on-a-chip,” that use multiple organ-specific human cells to recapitulate many functional and structural properties of a human organ. It is now generally accepted and supported by data that cellular responses to drugs in most human organs are more accurately approximated in 3D cell cultures than in traditional static 2D cell cultures5,6. Microfluidic perfusion further improves model performance by providing a flow of nutrients and oxygen and the removal of waste products from the cell cultures. Physiologically relevant flow increases oxygen consumption, Krebs cycle activity and secretion of synthesized proteins, and decreases expression of the hypoxia HIF1 gene. Flow also improves the absorption and metabolism of compounds like benzo[a]pyrene6,8,9. The large number of recent publications reviewing organ MPS models indicates a high degree of interest by industrial and academic researchers, granting agencies and other stakeholders10,11,12,13. In addition to the stand-alone MPS, investigators are linking MPS to study organ-organ functional interactions, efficacy, PK and toxicology14,15,16,17,18.

An obvious approach to linking organs is direct coupling of the media stream outflow from one organ into the inflow of the next by use of tubing or a connecting channel. Some limitations to this approach include the requirement for a common medium, difficulty in reducing metabolic wastes to the next organ, organ-specific flow rates and adequate oxygenation of all modules in the system19. These requirements are most easily addressed when the linked organ modules are designed and developed at the same time and in the same laboratory, but even when the organ modules are co-developed, the proper scaling between organ modules is a significant design and calculation challenge. Although organ modules can be sized using allometric scaling20, the resulting functional capacity of the individual organ models may not scale the same.

Interesting read for those interested in inorganic protein (NP) states from a solid to a liquid as the research proves inorganic NPs are in a ‘glassy’ state while transitioning from a solid to a liquid form.

Molecular dynamics simulations of ubiquitin in water/glycerol solutions are used to test the suggestion by Karplus and coworkers that proteins in their biologically active state should exhibit a dynamics similar to ‘surface-melted’ inorganic nanoparticles (NPs). Motivated by recent studies indicating that surface-melted inorganic NPs are in a ‘glassy’ state that is an intermediate dynamical state between a solid and liquid, we probe the validity and significance of this proposed analogy. In particular, atomistic simulations of ubiquitin in solution based on CHARMM36 force field and pre-melted Ni NPs (Voter-Chen Embedded Atom Method potential) indicate a common dynamic heterogeneity, along with other features of glass-forming (GF) liquids such as collective atomic motion in the form of string -like atomic displacements, potential energy fluctuations and particle displacements with long range correlations (‘colored’ or ‘pink’ noise), and particle displacement events having a power law scaling in magnitude, as found in earthquakes. On the other hand, we find the dynamics of ubiquitin to be even more like a polycrystalline material in which the α-helix and β-sheet regions of the protein are similar to crystal grains so that the string -like collective atomic motion is concentrated in regions between the α-helix and β-sheet domains.
