Preformulation and Formulation Development

Optimizing Conformational Stability and Biological ActivityMaintenance of the native three dimensional conformation is critical for the long term stability and biological activity of biotherapeutics. Biophysical characterization techniques such as circular dichroism, differential scanning calorimetry, FTIR, dynamic light scattering, and fluorescence spectroscopy provide a mechanism to assess the conformational and thermodynamic stability of proteins under a range of formulation conditions. These tools allow development scientists to differentiate various various buffer, pH, ionic strength, and excipient conditions, and identify the conditions that confer the optimum environment for the therapeutic protein.

Utilizing Advanced Statistical Design for Preformulation Development Preformulation development includes statistical design of experiments, allowing simultaneous evaluation of multiple factors and evaluation of interactions between factors. It is crucial to use advanced biophysical characterization techniques to evaluate the conformational stability of large molecules in addition to traditional methods for evaluation of chemical stability.

A large molecule preformulation development program typically includes the following activities:
Evaluate the effect of pH, buffer type, and ionic strength on solubility.
Evaluate the effect of various excipients on improving solubility if necessary.
Evaluate effects of pH, buffer type, and excipients on conformational stability.
Evaluate the effect of pH, buffers, excipients and ionic strength on physical and chemical stability.
Utilize a statistical design approach to identify the optimal conditions for structural, physical and chemical stability.
Perform forced degradation to elucidate product degradation pathways and to demonstrate the stability-indicating capacity of the analytical methods.
Forced degradation studies typically include restricted oxidation, deamidation, aggregation (via agitation), and / or acid / base hydrolysis.
Evaluation of heat stress, photo stress, and freeze thaw are also performed.

Formulation scientists are highly skilled in the development of the dosage forms most relevant to biotherapeutics, with particular expertise in lyophilization and development of stable liquid formulations for proteins. High concentration antibody formulation development for subcutaneous administration requires particular emphasis on viscosity and tonicity. Lyophilization cycle development is performed in the context of the unique thermodynamic properties of the API to deliver an efficient, scalable, transferable process resulting in optimum product stability and reconfiguration characteristics. Formulation development capabilities also include:

Effect of excipients on solubility, tonicity, and viscosity Evaluation of antioxidant and conservative compatibility Container-closure compatibility Long term and accelerated stability studies.

Advantages of Formulation Development Approach. This outlined approach to preformulation and formulation development result in significant savings to the client by eliminating the variables associated with suboptimal formulations. Preclinical development efforts in PK, PD, ADME and toxicology occur with confidence that additional uncontrollable variables from unstable formulations are not introduced into the study. This benefit extends far into clinical trials as well, where assessment of toxicity, dosage levels and efficiency are substantially influenced by an optimal formulation that preserves the three dimensional conformation of the therapeutic protein. By eliminating uncontrolled stability variables, the focus is placed solely on the therapeutic performance and clinical outcome.

Freshwater Aquarium Maintenance – Top 4 Areas You Should Not Ignore

Freshwater aquarium maintenance is a priority for any tank owner who wants to display a variety of healthy vibrant fish. Having a filthy fish tank will only cause issues for your little swimmers as well as the room you have your display. If you do not want unusual odors surfacing, or waking up one morning only to see some of your species floating upside down, there are a few things to check for.

First , the all important water in the aquarium must be maintained. This is where you can look into purchasing filters that will make your water maintenance self-cleaning. That's right, filters will help get rid of dirt, odor, discoloration and any general impurities.

The downside is that depending on the filter, you may have to change them every 3-4 weeks. If this is not a problem then you're in for a real treat. Some filters are disposable and can be replaced so there is no hassle, and you can keep the water clean.

Second , Algae are one of the most common problems and can ruin even the most beautiful tanks becoming an eye sore to you and other viewers. There are a few remedies you can use to combat the algae, such as purchasing Plecostomus. Known as algae eaters, this fish will chomp away keeping your freshwater aquarium clean as can be. These fish are not known to be "lookers" but they will get the job done. If you rather pass on the species then you may have to remove them by hand. If you want to remove by hand but you want to minimize the amount you do remove, consider that any exposure to sun will allow the algae to thrive.

Third , you walk into the room where your fish tank is located and you notice a strong scent, what do you do? Change your filter more regularly to ensure this does not occur often, because this can kill your fish if it goes untreated.

Fourth thing should not ignore is unclear water. Is your freshwater aquarium looking a little murky? Determine the "root" cause, possibly your overfeeding. Try not to give your fish more than the recommended amounts instead feed them 2-3 times daily. This will reduce the unclear water, if not use use distilled water or bottled water.

Change the water at least every two weeks if not every week but only about 20 percent of it. Many use siphons to drain the water and then replace it. Understand that eventually the aquarium tank will need to be cleaned which can be a pain experience for many. As bad as the experience may be you have to do it if you want your fish to stay healthy. During this process, use a sponge and gently scrub the aquarium glass and remove everything that is stuck there. Some opt to use scrapers but if you have an acrylic aquarium, this process can be damaging. Soak any decorations you have in your aquarium in hot water with a bit of salt and scrub clean. Do not use soap; the residue will kill your fish very quickly.

Finally , when refilling your tank remember to keep the water temperature the same as the fish can live in. Important Tip: Do not use water from the faucet because it is not designed to help the fish, instead boil 5-10 gallon bucket of distilled water let it cool and use.

How to Get Approved For an Apartment Even With a Criminal Record

One of the most frustrating episodes ones can encounter is a denial of housing. Apartment complexes, which in reality are run by real estate management firms, use a number of factors to determine who should rent and who should not. One of the most common factors that they use is criminal background check. A criminal history can be one of the greatest huddles one can ever come across in the process of renting an apartment.

The reason apartment communities request a criminal background check is first of all for the safety of the overall community. There is a general consensus that people with violent pasts are bound to fall back into their previous destructive habits. The concept of history repeats itself seems to be a prevailing belief in many places when it comes to criminal history and nowhere more so than in apartment leasing offices.

Another reason why apartment leasing offices conduct a criminal background check is so as to create the appearance of safety in the community and in so doing have the justification to charge more for rent. If a neighborhood or apartment housing community has a high level of crime, then tenants will not want to renew their leases and this means that there will be more housing units which are vacant and which the management has to fill (or risk being censored by the owner). The more housing units are vacant in an apartment community the more it hurts the management bottom line because this drives down the rent.

When conducting criminal background checks, apartments normally concentrate on felony convictions. Misdemeanor crimes which are only punishable by fines are generally not a concern. If you have a misdemeanor, you should not be concerned but if it is a felony you may get a denial.

There are two main ways to get an apartment approval if you have a criminal record. The first one is to check the nature of your offense and see whether you received what is called a deferred adjudication. This is a probation granted to first time offenders and is also known as community supervision. If you were convicted of a misdemeanor, and got probation, you can go to the county clerk’s office and request for what is called a court deposition. This is a print-out that shows the offense, the court that heard the case, and the judgment that was rendered and the fact that you have deferred adjudication. The printout also states that you have successfully completed the community service without any other incidences and that you should not be discriminated against when it comes to services. You can take a copy of this document to an apartment manager and in most cases they will approve you.

Another way to get an apartment is to get an expungement. This is the sealing of your criminal records and can be done depending on whether you’re eligible.
