The analysis of dissolved inorganic carbon in liquid using a microfluidic conductivity sensor with membrane separation of CO2.

The analysis of dissolved inorganic carbon in liquid using a microfluidic conductivity sensor with membrane separation of CO2.

Autonomous steady analysis of oceanic dissolved inorganic carbon (DIC) focus with depth is of nice significance with regard to ocean acidification and local weather change. However, miniaturisation of in situ analysis programs is hampered by the dimensions, price and energy necessities of conventional optical instrumentation.

Here, we report a low-cost microfluidic various based mostly on CO2 separation and conductance measurements that would result in built-in lab-on-chip programs for ocean float deployment, or for moored or autonomous floor car purposes.

Conductimetric willpower of focus, in the seawater vary of 1000-3000 µmol kg-1, has been achieved using a microfluidic thin-film electrode conductivity cell and a membrane-based fuel alternate cell. Sample acidification launched CO2 by means of the membrane, reacting in a NaOH service, later drawn by means of a sub-µL conductivity cell, for impedance versus time measurements.

Precision values (relative normal deviations) had been ~ 0.2% for peak peak measurements at 2000 µmol kg-1. Comparable precision values of ~ 0.25% had been obtained using a C4D electrophoresis headstage with related measurement quantity.

The required complete pattern and reagent volumes had been ~ 500 µL for the low quantity planar membrane fuel alternate cell. In distinction, earlier conductivity-based DIC analysis programs required complete volumes between 5000 and 10,000 µL. Long membrane tubes and macroscopic wire electrodes had been prevented by incorporating a planar membrane (PDMS) in the fuel alternate cell, and by sputter deposition of Ti/Au electrodes instantly onto a thermoplastic (PMMA) manifold. Future efficiency enhancements will handle membrane chemical and mechanical stability, additional quantity discount, and part integration into a single manifold.

Overcoming the bottleneck to widespread testing: A fast assessment of nucleic acid testing approaches for COVID-19 detection.

The present COVID-19 pandemic presents a severe public well being disaster, and a higher understanding of the scope and unfold of the virus could be aided by extra widespread testing. Nucleic-acid based mostly checks at the moment supply essentially the most delicate and early detection of COVID-19.

However, the “gold normal” take a look at pioneered by the United States Center for Disease Control & Prevention, takes a number of hours to finish and requires intensive human labor, supplies comparable to RNA extraction kits that would turn out to be in quick provide and comparatively scarce qPCR machines. It is evident that a enormous effort must be made to scale up present COVID-19 testing by orders of magnitude. There is thus a urgent want to guage various protocols, reagents, and approaches to permit nucleic-acid testing to proceed in the face of these potential shortages.

There has been a great explosion in the quantity of papers written throughout the first weeks of the pandemic evaluating potential advances, comparable reagents, and options to the “gold-standard” CDC RT-PCR take a look at.

Here we current a assortment of these latest advances in COVID-19 nucleic acid testing, together with each peer-reviewed and preprint articles. Due to the fast developments throughout this disaster, we’ve got included as many publications as potential, however many of the cited sources haven’t but been peer-reviewed, so we urge researchers to additional validate outcomes in their very own labs.

We hope that this assessment can urgently consolidate and disseminate data to assist researchers in designing and implementing optimized COVID-19 testing protocols to extend the supply, accuracy, and velocity of widespread COVID-19 testing.

Corona virus stays problematic

Harvar Epidemiologist sounds the alarm
Coronavirus worse than expected
Harvard epidemiologist explains.

Dr. Eric Feigl-Ding, a Harvard-trained epidemiologist who taught at the school for 15 years, published his alarming analysis of the corona virus outbreak on Twitter Saturday and called the virus “thermonuclear pandemic level poor” and declared “I really hate to the epidemiologist who must admit this, but we may be confronted with an uncontrolled pandemic that the world has not seen since the Spanish flu of 1918. “

His full Twitter thread is shown below:

Dr. Eric Feigl-Ding
@DrEricDing
HOLY MOTHER OF GOD – the new coronavirus is a 3.8!!! How bad is that reproductive R0 value? It is thermonuclear pandemic level bad – never seen an actual virality coefficient outside of Twitter in my entire career. I’m not exaggerating… #WuhanCoronovirus #CoronavirusOutbreakDr. Eric Feigl-Ding

Replying to @DrEricDing
2/ “We estimate the basic reproduction number of the infection (R_0) to be 3.8 (95% confidence interval, 3.6-4.0), indicating that 72-75% of transmissions must be prevented by control measures for infections to stop increasing…

Dr. Eric Feigl-Ding
@DrEricDing
3/ … We estimate that only 5.1% (95%CI, 4.8-5.5) of infections in Wuhan are identified, and by 21 January a total of 11,341 people (prediction interval, 9,217-14,245) had been infected in Wuhan since the start of the year. Should the epidemic continue unabated in Wuhan….
4/ we predict the epidemic in Wuhan will be substantially larger by 4 February (191,529 infections; prediction interval, 132,751-273,649), infection will be established in other Chinese cities, and importations to other countries will be more frequent. Our model suggests that..
5/ travel restrictions from and to Wuhan city are unlikely to be effective in halting transmission across China; with a 99% effective reduction in travel, the size of the epidemic outside of Wuhan may only be reduced by 24.9% on 4 February. Our findings are…
6/ …critically dependent on the assumptions underpinning our model, and the timing and reporting of confirmed cases, and there is considerable uncertainty associated with the outbreak at this early stage. With these caveats in mind, our work suggests that…
7/ a basic reproductive number for this 2019-nCoV outbreak is higher compared to other emergent coronaviruses, suggesting that containment or control of this pathogen may be substantially more difficult.”!!!! #wuhanvirus #CoronavirusOutbreak #ChinaCoronaVirus …

Western Blot antibodies

Western blot uses monoclonal and polyclonal antibodies.

Western blot does not recognize proteins. Western blot monoclonal antibodies recognize a protein which is present in natural cell supernatant or fluid named an antigen.

The antigen has an epitope. Usually the epitopes used to inject mouse for monoclonal and rabbits for polyclonal antibodies are not larger than 35 amino acids and larger than 10 amino acids.

Alternatively whole protein can be injected with KLH into mouses or rabbits.

Monoclonal recognize one specific epitope or part of that epitope.

Poly-clonal antibodies recognize different epitopes but since in an epitope of only 35 amino acids is very small most polyclonal are like virtual monoclonal antibodies. Often there is 1 dominant epitope even in whole protein immunizations.

Antibodies are very powerful tools. dilution of 1/500 are used for WB incubation. Most companies sell 100 ul that will give 50 ml of incubation reagent. Concentrations are often 100 ug /ml. Santa Cruz, in California close to San Francisco sells 200 ul antibody vials.

Western blot can discriminate between proteins which are present in natural serum of cell extract and they cannot differentiate between DNA.

An example of this is when antigens are found in both cell supernatural or cell extract for extracellular proteins.

Only when antibodies are bound to a molecular marker or to a secondary anti rabbit or mouse, than a response will be generated.

In the human body, Antibodies are essentially used to avoid rejection of the transplanted cancerous cells. Antibodies bound to antigens produced by the cancer cells, the antibodies will prevent them from being properly accepted by the host cells. Antibodies are also necessary in diagnosing and in treating cancer. The antibodies can be used to identify cancer cells, but there are other techniques which use antibodies. Antibodies are also used to protect cells from natural or synthetic contaminants. A lot of research has been done in the last few years to detect cancer cells. The antibodies in cancer cells can block the effectiveness of immune cells in fighting cancer.
