Reagent

A reagent is an integral part of any chemical reaction. A reagent is a substance or compound that can facilitate a reaction, and they are used in the most commonly used tests. This includes, for example, pregnancy tests, blood glucose tests, and most COVID-19 test kits.

Reagents in chemistry

Reagents trigger chemical reactions. This term encompasses organic substances that trigger natural chain reactions in the body but also includes inorganic substances that can be used in artificially triggered reactions. Reagents are commonly used to test for the presence of certain substances, as the binding of the reagents to the substance or other related substances triggers certain reactions.

While sometimes used interchangeably with the term “reagent,” reagents and reagents are quite different. In a chemical reaction, a reactant binds to something and thus triggers a reaction. It is not consumed during this. However, a reactant is consumed. A reactant is a substrate in a reaction, while a reactant is a catalyst.

Rulers can also be limiting. Limiting reagents stop a chemical reaction when they are used up. The chemical reaction depends on the reactant to continue the reaction and stops when there is no more substance. Limiting reagents, therefore, dictate when a certain chemical reaction does not proceed.

The reagents are commonly used in laboratory settings for various tests. For example, Collins’ reagent is used to convert alcohols to aldehydes and ketones. As such, it can be useful for oxidizing acid-sensitive compounds. Fenton’s reagent, similarly, is used in the oxidation. However, Fenton’s reagent catalyzes the oxidation of contaminants in water and can be used to remove toxic compounds, such as tetrachlorethylene.

Reagents are often used to indicate the presence of compounds by causing changes in colours to indicate presence. For example, Fehling’s reagent can indicate whether carbohydrates or ketones are present and differentiate between the two functional groups. Millon’s reagent can be used to indicate the presence of proteins. The presence of protein, as inferred from the presence of tyrosine residues, causes the solution to which Millon’s reagent has been added to take on a reddish-brown colour.

Reagent kits and how they are used

Reagents, such as those listed above, are commonly used in laboratory or field settings to detect the presence of a variety of substances. For example, one of the widespread uses of reagents in everyday life is the detection of illegal drugs. While most kits, such as those used to test common drugs, are easy to use and involve noticing if there is a colour change, other kits are more complicated and require laboratory equipment such as chromatography.

Mandelin reagent kits are commonly used to detect alkaloids. This means that the kit can turn dark green if the drug amphetamine is present, and cocaine turns the color deep orange. Similarly, Marquis reagent kits can detect the drug LSD by turning olive-black when the drug is present in the solution. Marquis reagent kits can also test for methamphetamine and a variety of other drugs.

Reagents during COVID-19 testing

There are two main methods by which COVID-19 tests are performed: antibody tests and PCR-based tests. Both rely on reagents to successfully test for COVID-19 infections. In antibody tests, the compound that is detected in the reagent test kit is the antibody against the COVID-19 virus. In these cases, the patient’s blood is analyzed with enzymes as reagents. Test reagents bind to antibodies, such as IgG and IgM, and if they are present, a line will indicate this on the test kit. These tests are quick to perform and can indicate previous infection with the virus.

PCR, or polymerase chain reaction, tests whether the genetic material of the COVID-19 virus is present in the blood. Using real-time reverse transcription PCR (RT-PCR), the reagents used are enzymes to detect the specific genetic material, which is very unique to the virus. This is a more complicated form of the reagent test kit as it requires chromatography techniques. Lateral flow device (LFD) tests for COVID-19 have been developed later in the pandemic, to provide rapid, large-scale testing, for example in schools. detect antigens

However, as with other forms of reagents, those used to test for COVID-19 are limited and prone to problems in production and trade. Especially in a pandemic environment, this has become an issue, as previously laboratories and producers were operating at much lower capacity compared to the current need and a shortage of reagents on the same scale has never been encountered before. There are different reagents that are used to extract the virus or viral materials, others to amplify this, and then other reagents to test for its presence.

Polyclonal Antibodies

What are polyclonal antibodies (pAbs)?

Polyclonal antibodies (pAbs) are a complex mixture of various antibodies that are usually produced by different clones of B cells from an animal. These antibodies recognize and bind to many different epitopes on a single antigen and thus can form networks with the antigens.

How are polyclonal antibodies generated?

Antigen preparation

The quality and quantity of the antigen used directly affect the immune response. Even small amounts of impurities will cause the antibodies to react more to the impurity than to the desired antigen. Too little or too much antigen can cause sensitization, suppression, or other unwarranted immunomodulatory effects. Therefore, antigen purification is a crucial process to achieve higher antibody specificity.

The antigen must be prepared under sterile conditions to ensure that it is free from endotoxins. The amount of antigen depends on several factors, such as the properties of the particular antigen, the animal species chosen, the route of injection, the frequency of injection, and the level of purity of the antigen.

Selection of animal species

Factors that influence the choice of animal species are the amount of pAb required, the phylogenetic relationship between the animal and the antigen, the age of the animal, the ease of obtaining blood samples, and the application in which the pAb is used.

Animal species commonly used in the laboratory are rabbits, rats, mice, guinea pigs, hamsters, goats, chickens, and sheep. Rabbits are preferred due to their size and relatively long lifespan. However, to produce higher amounts of pAbs, farm animals such as goats, sheep, and horses are used.

Vaccination protocol

The immunization protocol differs for different animal species. Adjuvants are compounds that are used as a form of stimulation in cases where the induced immune response would otherwise be inadequate. The most widely used adjuvant for the production of pAbs is Freund’s complete adjuvant (FCA).

FCA induces high antibody titers against most types of antigens. However, care must be taken that FCA is not over-administered. FCA use should be limited to one-time use, as FCA can cause serious tissue damage. The smallest volume of an antigen capable of inducing an effective immune response is injected into the animal. However, the route of injection depends on the nature of the antigen and the animal used. The antigen can be injected as a single volume or several low volumes at different sites.

Booster injections are given if the antibody titer concentration has reached a plateau or is declining. Such injections do not always require an adjuvant, and very small amounts of the antigen are sufficient to enhance antibody concentration. A maximum of three booster injections is recommended.

Post-immunization observation

Animals are monitored daily for side effects of immunization and bled at regular intervals. Serum from animals is tested to monitor antibody responses and extract antibodies when a sufficient amount is produced.

Advantages of polyclonal antibodies

This is a relatively inexpensive process and can be used to isolate large quantities of an antibody in a single extraction. PAbs are a heterogeneous mixture of antibodies that can bind to a wide range of antigenic epitopes. Therefore, a small change in the epitopes of an antigen is less likely to affect pAbs. These antibodies are very stable over a wide range of salt concentrations and pH values.

Disadvantages of polyclonal antibodies

The affinity of pAbs for antigens can change over time, leading to a lot of lot-to-lot variabilities. Furthermore, the amount of pAbs produced is limited by the size and lifespan of the animal. The purity and concentration levels of a specific antibody are lower in pAbs than in monoclonal antibodies.

How are polyclonal antibodies used?

pAbs have a wide range of applications, including diagnostic tests and qualitative and quantitative biological analyses. For example, pAbs are used in immunofluorescence and immunohistochemical techniques such as sandwich ELISAs to detect tumour markers and other proteins of interest. pAbs are also used for mediating or modulating purposes, such as in immunotherapy, active signalling, or for neutralizing activities. An example of this is the use of pAbs in the treatment of Digoxin Immune Fab in fatal digoxin toxicity.

pAbs such as Rho (D) immunoglobulin are injected into mothers with negative Rhesus blood group to prevent hemolytic disease in a newborn. Rho (D) is produced from a pool of human plasma collected from Rhesus negative donors who have antibodies against the D antigen (present on red blood cells). pAbs also find applications in histopathological analyzes employing immunoperoxidase staining. In addition to these applications, pAbs are used in immunoaffinity purification for the purification or enrichment of antigens.

Recombinant pAbs are used in cancer therapy due to their ability to target multiple tumour cells compared to monoclonal antibodies. Although monoclonal antibodies are widely used in cancer therapy, relapse is common due to the appearance of tumour cells that are resistant to the antibody. By using pAbs, various recombinant antibodies can be developed that cross-react with different types of cancer.

The way forward shows the use of recombinant pAbs to minimize unnecessary polyreactivity as seen when using traditional pAbs. The use of pAbs in different assays not only leads to high throughput but can also be used to develop antibodies specific for human gene products that are also renewable.

Factors influencing scientific achievements of medical students in the Anatomy Research Group: An analysis from the Autonomous University of Nuevo León in Mexico

Scientific analysis and scholar involvement are essential to the formation of physicians, but the variety of medical researchers has decreased over time. To implement corrective methods, the variables related to constructive analysis attitudes and productiveness amongst medical college students have to be recognized. The intention of this examine was to judge the variables related to college students or concerned in analysis. A validated questionnaire was utilized to the coed members of a longtime anatomy analysis group in a Mexican medical faculty with a six-year medical program. Information have been collected and analyzed.

A complete of 85.5% (n = 77/90) answered the survey with most respondents being second-year medical college students. An important element of conducting analysis was acknowledged to be contributing to new data (45.5%) and to the scientific group (42.9%) by most respondents. Greater than half point out a professor or a peer because the preliminary motivation to turn out to be concerned in analysis. Lack of time was the principle limitation (59.7%) to analysis involvement. Perceived advantages have been data and team-work expertise. Of these concerned, most (85.7%) wished to proceed collaborating in analysis as a complement to their medical work.

to focus on the principle attributes of Convergent Care Analysis that ratify it as a way of scientific analysis. Strategies: it’s a theoretical-reflective examine on Convergent Care Analysis’s theoretical-methodological assumptions. Improvement: Convergent Care Analysis is appropriate with the Social Constructionism paradigm. Convergent Care Analysis initiatives have two approaches: sensible and conceptual. The Convergent Care Analysis course of corpus incorporates 5 phases: conception; instrumentation; scrutiny; evaluation and theorizing.

Remaining Concerns: Convergent Care Analysis rigor encompasses the connection between analysis and care observe, and this corresponds to the convergence of those two dimensions. Attributable to its theoretical basis and standards of methodological rigor, Convergent Care Analysis is aligned with scientific analysis strategies. Professors and scholar colleagues have been discovered to play an necessary motivational and recruitment position for medical analysis. These efforts in flip will become mentor-mentee relationships. Early involvement in analysis as a scholar is anticipated to positively affect the probability of future physicians contribution and collaborating in analysis.

Reporting consciousness in coma: media framing of neuro-scientific research, hope, and the response of families with relatives in vegetative and minimally conscious states

Reporting consciousness in coma: media framing of neuro-scientific research, hope, and the response of families with relatives in vegetative and minimally conscious states

This paper examines the general public illustration of, and household responses to, scientific research into consciousness in coma-like states. We look at the publicity surrounding high-profile research utilizing purposeful Magnetic Resonance Imaging (fMRI) on ‘vegetative’ or ‘minimally aware’ sufferers and evaluate this with household views. Our findings present how, with a couple of notable exceptions, the analysis was offered as a tremendous breakthrough providing a possible ‘voice’ and selection for sufferers and hope and luxury for his or her households. We argue that such representations ignored key limitations, evoked unrealistic visions of restoration, and promoted very slim representations of household reactions.

The comparability between public representations of the science and responses from households with expertise of this situation highlights the complicated social/medical world into which neurotechnologies intervene, and factors to the absence of a variety of affected person/household views in public discourse. We conclude with recommendations for the way these selling the analysis, and the journalists reporting its implications, may act to make sure extra accountable protection and improve public debate.

First, we affirm earlier analysis in suggesting that e-cigarettes appeared to have triggered a breakdown of outdated public well being alliances. Second, we display that, amid issues about analysis high quality and amount, actors are guided by normative outlooks (and/or financial pursuits) of their assessments of proof. Third, we present that, regardless of describing e-cigarette debates as contentious and polarised, actors partaking in Scottish coverage debates exhibit a spectrum of views, with most interviewees occupying an unsure ‘center floor’ that’s attentive to new proof.

Fourth, we propose that the perceived divisiveness of e-cigarette debates is attributed to recurrent media simplifications and tensions arising from the behaviours of some actors with settled positions working to advertise explicit coverage responses (together with by strategically enrolling supportive proof). Fifth, we argue that the actions of those actors are doubtlessly defined by the prospect that e-cigarettes may usher in a brand new tobacco ‘coverage paradigm’. Lastly, we present how scientific authority is employed as a device inside these debates.

Chemosensory Programs in COVID-19: Evolution of Scientific Analysis

COVID-19 illness induced by coronavirus SARS-CoV-2 presents amongst its signs alterations of the chemosensory capabilities. Within the first research on the Chinese language inhabitants, this symptomatology was not notably related, and hyposmia and hypogeusia have been excluded from the signs to be evaluated to diagnose the illness. With the pandemic unfold of the sickness, there was an increase in reviews on chemosensory dysfunctions amongst sufferers. The primary information evaluation confirmed the presence of those problems primarily in paucisymptomatic and asymptomatic sufferers. The curiosity in chemosensory techniques due to this fact elevated significantly, as a result of the olfactory and gustatory signs could possibly be the important thing to cease the an infection unfold.
Moreover, the diploma of alert and a focus grew, contemplating that these kind of dysfunctions are prognostic signs of significant neurodegenerative illnesses. About 9 months have handed because the first anecdotal reviews on the involvement of the olfactory and gustatory techniques within the COVID-19 pathology. Because of this, a cautious evaluation of the literature was performed to grasp whether it is clearer which individuals current chemosensory signs and if these are associated to the severity of the illness. Moreover, we have now recognized which facets nonetheless stay to be clarified. This novel consequence may be defined with self-determination of students as an important determinant supporting scientific manufacturing that outclasses shrinking public analysis lab budgets and organizational deficiencies.
Throughout the early levels of the pandemic, analysis performed on hydroxychloroquine (HCQ) was chaotic and sparked a number of heated debates with respect to the scientific strategies used and the standard of data generated. Analysis on HCQ is used as a case research in each papers. The authors explored biomedical databases, peer-reviewed journals, pre-print servers, and media articles to establish related literature on HCQ and COVID-19, and examined philosophical views on medical analysis within the context of this pandemic and former world well being challenges.

fiddle: a tool to combat publication bias by getting research out of the file drawer and into the scientific community

Statistically important findings usually tend to be revealed than non-significant or null findings, leaving scientists and healthcare personnel to make choices based mostly on distorted scientific proof. Repeatedly increasing ´file drawers’ of unpublished information from well-designed experiments waste assets creates issues for researchers, the scientific group and the general public. There may be restricted consciousness of the unfavourable impression that publication bias and selective reporting have on the scientific literature.

Various publication codecs have lately been launched that make it simpler to publish analysis that’s tough to publish in conventional peer reviewed journals. These embody micropublications, information repositories, information journals, preprints, publishing platforms, and journals specializing in null or impartial outcomes. Whereas these different codecs have the potential to scale back publication bias, many scientists are unaware that these codecs exist and do not know how one can use them.

Our open supply file drawer information liberation effort (fiddle) software is a match-making Shiny app designed to assist biomedical researchers to establish essentially the most applicable publication format for his or her information. Customers can seek for a publication format that meets their wants, evaluate and distinction totally different publication codecs, and discover hyperlinks to publishing platforms. This software will help scientists in getting in any other case inaccessible, hidden information out of the file drawer into the scientific group and literature.

Pitfalls in scientific analysis: vital appraisal of articles revealed in one of many worldwide journals in Egypt

To establish and report flaws of Web-published articles within the Journal of the Egyptian Nationwide Most cancers Institute (JENCI), Cairo College, by means of a retrospective documentary research on articles revealed through the interval from 2011 to 2016. All sections have been reviewed in opposition to a collective guidelines. Articles have been grouped by publication yr into 2 intervals: early (from 2011 to 2013) and up to date (from 2014 to 2016) to establish adjustments in research traits over time. The research included 139 unique articles. Half of the titles represented purpose and 9.4% represented research design.
Abstracts have been concise, clear, with structured writing format in 98.6%, 93.5%, and 35.3%, respectively. Most introductions included the research purpose, whereas 41% had a rationale. Examine timing was reported in 59.0%, whereas the research design was reported in 25.9%. Inclusion and exclusion standards have been clearly reported in 43.1% and 40.1%, respectively. Statistical strategies have been talked about in 80.6%, full in 30.4%, and applicable in 85.7%. We briefly spotlight important particulars that ought to be included to make sure reporting high quality, which is able to enable others to make use of and profit from analysis revealed in these new codecs.
4 research reported pattern measurement estimation. Solely 52.5% and 58.3% of outcomes have been exhaustive and reply the analysis query, respectively. Incorrect statistical calculations occurred in 41.0%, inappropriate statistical checks or descriptive parameter choice in 26.6%, whereas inappropriate take a look at software occurred in 49.1%. About 60% of discussions didn’t fully cowl outcomes, 31.7% totally justified the findings, 56.1% adopted a logical circulate, and 36.7% had contradiction inside the textual content. Conclusions have been principally linked to purpose, imprecise, and extrapolating past outcomes.
On evaluating each intervals, solely a major much less misuse of statistical phrases, extra reporting battle of curiosity, extra lacking references for cited texts within the current interval, and extra participation of NCI over different institutes within the early interval have been discovered. Articles revealed in JENCI (from 2011 to 2016) had many methodological and reporting defects and a few factors of energy. Utilizing the collective guidelines developed by this research, steady coaching of researchers, involving epidemiologists all through the entire analysis course of, and making use of strict journal reporting and publication guidelines ought to be inspired.
fiddle: a tool to combat publication bias by getting research out of the file drawer and into the scientific community

Scientific integrity among nursing students participating in the Scientific Initiation Program: An exploratory study.

To determine the position and practice adopted by nursing students in scientific initiation program on the principles of scientific integrity in various stages of the process of doing science.An quantitative exploratory study, in which participants from the nursing students Scientific Initiation Program of the federal District interviewed.

Fifty (50) nursing students participated in the study. Most participants were interviewed presented a good understanding of the process of doing research in different stages. However, it was found that although they were familiar with the practices of good science, students do not always behave in the most responsible way.

It was observed that the knowledge on topics related to the ethics of the scientific process is mainly obtained through formal education, which consists of classes and courses. Nevertheless, the importance of complementary spaces such as study and research groups recognized.

Conclusion: Research experience that education and vocational training room are important for students. Hence, good research practice need to be incorporated at the beginning of the academic curriculum.
