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 Development for Numerous Dosage FormsFormulation development includes dosage forms for parenteral, oral topical and inhalation administration, including liquids, gels, suspensions, emulsions and lyophilized powders. 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.

Simferopol, the Capital of Crimea – Simferopol City Guide

Simferopol is known as the capital and biggest city of Crimea. Every year millions of tourists go through this city to the Crimean resorts, such as Yalta, Sevastopol and Evpatoria. Today Crimea belongs to Ukraine and is its most southern region. After the collapse of the USSR in 1991, former Soviet Republics declared their independence, new countries emerged and Ukraine was one of them.

Simferopol is a pretty old, ancient city. Different civilizations occupied the area where the city is now situated over centuries. Finally, the city of Simferopol was founded by Russians in 1885. In old Greek Simferopol means a city of common good, or city-collector. The city was involved in many wars and battles during its long history. During the Second World War the Crimean region was tormented by the Nazi Germany. They took occupation of the city and used it as a strong base to withstand many attacks. Really, the history of this city is so rich! There is a number of historical attractions and artifacts which makes Simferopol a popular tourist destination for many tourists visiting it every year.

At present the total population of Simferopol is reported to be around four hundred thousand people. Administratively, the city is divided into 3 divisions. Due to its central location on the Crimean peninsula, it is a convenient place for many industries and facilities. Food and engineering industries are the two key ones that were developed in the city years ago, in the Soviet time. However more business is being established here today and the economics of the city keeps growing.

Simferopol has always been a cultural and educational center of the Crimea region. There are several Universities and many more colleges in the city. It is not surprising that Simferopol is called a student city sometimes. This city is also known with its famous theaters, such as the Crimean Academic Russian Drama Theater, Simferopol Puppet Theater and Crimean Ukrainian Music Theater. The city’s main public transport system consists of trolleys and buses that run throughout the city and connect the central area with suburbs. The Simferopol International Airport in the only one in Crimea. Different Ukrainian and international airlines have daily flights to Simferopol from Kiev, Moscow, Istanbul, and in summertime Simferopol is also connected with Germany, Israel, Armenia, Latvia, Uzbekistan and other countries. The majority of tourists get to Simferopol by train through. This transportation remains the most popular one in Ukraine due to affordable prices and a decent level of comfort the trains provide.

Since Simferopol is the capital of the Autonomous Republic of Crimea, the city is responsible for the administrative duties related to the special administrative status of Crimea within Ukraine. The Parliament of Crimea as well as the Cabinet of Ministers and other administrative institutions of the Crimean Republic are situated in Simferopol. Although Crimea has the status of a republic, the Crimean Parliament is subordinate to the Supreme Parliament of Ukraine which is situated in Kiev, the capital city of Ukraine.

Today Simferopol is a political, administrative, educational and cultural center of Crimea and of the whole Southern region of Ukraine as well as a popular tourist destination.

Demonetisation: Impact on E-Commerce Platforms

India is still recovering from the unexpected demonetization of rs 500 and rs 1000 notes. A huge change is encountered in the routine of every business and the e-commerce industry has not been spared even. One of the most significant economic change in the lifetime of Indians experiencing vast tremors. While some people were hailing it as a masterstroke move against against black money, terrorism, and currency counterfeiting. Whereas, certain section of people were creating hue and cry against it. This change is placing a tremendous impact on trade and consumer demand. A lot of discussions and discussions are already going on these topics, so I will spare you on that!

The e-commerce platforms are reeling under pressure due to undelivered orders because a lot of customers have opted for COD, but are still offering the old currency notes only. Such drastic economic change has led to an increase in the use of cashless services but the e-commerce platforms are finding it very difficult to complete orders that have been marked for cash on delivery.

On one hand, there have been a huge increase in digital payments but on the other hand the percentage of undelivered online purchases too have gone up. All of this has claimed in huge returns as the customers who place online orders and choose for COD mode for payments, urge the delivery person to accept the old currency notes or take back the order.

Due to demonitisation, the e-commerce platforms have stopped COD mode of payment which is credited for close to 60% of online shopping in the country. COD is one of the popular payment options for a large section of India consumers who shops online. This is due to the sheer convenience it offers to its customers who wish to receive their orders first and pay later.

In order to compensate, these platforms have added credit card on delivery as one of the payment options to put customers at some ease who are running out of cash. More discounts are offered by renovated websites on online payments as well as zero cost EMI schemes.

The spokesperson of amazon has said that the company has incurred ten times growth due to credit card on delivery mode. However, this is not helping the sellers much who have complained that these efforts are not compensating for the loss incurred over COD mode.

No doubt, there will be a lot of inconvenience in the initial period but in the long run, everyone is hopeful of a better growth, reduction in cash on delivery services, along with a quick return investment.

Mongofiles Review

Emailing large files can be a problem in many cases because majority of email providers place a limit of 25MB. Even if your files don’t exceed that limit, it can take a lot of time for it to upload. Fortunately, there are services that offer quick and hassle-free help. One of the most notable sites today is Mongofiles. Basically, users simply need to visit the provider’s site, select the file to be sent, and write the email address of the recipient.

Mongofiles uploads the file you choose into their server and then gives you a private link. Whoever receives this link can download the file immediately, safely, and quickly. The service is definitely a great solution for those who need to handle large files. Mongofiles allows you to send up to 2GB of files which is more than enough in 99% of cases.

It’s easy to see why the service offered by Mongofiles could be so attractive but there are similar websites out there. So how is it different? One thing that differentiates it is that the provider takes your security seriously. Here are other aspects you should consider:

• Private Link – other providers may offer the same file uploading service but a key selling point for Mongofiles is that they keep your files private. Only people you share the link to would be able to access the files. On the other hand, other providers make your files searchable for other users. There is no encryption or security features offered because they make money from people visiting their website to view potentially useful information.

• No Advertisement – many file uploading and sharing sites make their money from advertisement. That’s why if you register on these websites, expect your emails to be “sold”. Even if it isn’t sold to third-parties, you will still receive advertisements and offers from the company on your inbox.

• 30-Day Active Link – the closest thing to Mongofiles is probably YouSendIt. However, the latter only keeps your sharing link active for 7 days while Mongofiles links are valid for 30 days for the free service. Links on the premium service don’t expire. In many cases, this has proven to be useful because no one wants to keep uploading the files if the recipient lost it or if you need to keep track of files.

• Free Up to 100MB - if you like what you’ve read about Mongofiles so far, then go ahead and try it for yourself; it’s free. But keep in mind that the free service is limited to 100MB of files only. The company has a no-spam policy so you need not worry about your privacy. For those who need to send large amounts of files, 10GB of space is offered at $5 a month. Business users can take advantage of the 100GB of storage with 128-bit encryption. It is available for $50 a month.

Whether you are a personal user or a business user, Mongofiles offers something for everyone. When you compare their prices with online backup providers today, it also becomes clear that you can store so much more with this provider. Read Mongfiles reviews.
