Electrospinning: the most advanced method of drug delivery

Published

electrospinning drug delivery

At the pharmaceutical level, the need to improve and refine the methods of drug delivery in the body is an area of great importance. Unlike people commonly assume, the effectiveness of a drug is not based solely on its composition, but on its method of application. 

This fact becomes clear if we look at the different presentations that a drug can have regarding ways of being supplied. Likewise, in the creation and composition of the drug for therapeutic use, the best and most efficient ways of providing the treatment are evaluated. 

The need for a drug delivery system that controls and directs the active pharmaceutical ingredients is becoming increasingly evident to achieve a decrease in the adverse side effects of treatment. An example, the need for control in the release of drug’s API into the body is what happened to cancer patients.

The treatment against cancer is hugely abrasive to the patient’s body, and therefore, its administration must be strongly dosed to decrease the intensity of the adverse side effects in the person. However, this also reduces the effectiveness of the treatment.

Delivery directed specifically to the area of the tumour, increasing the effectiveness of the drug and reducing adverse effects. Different methods of encapsulation have been tested but have marked limitations that allow only reduced variables to be controlled, such as the speed of drug delivery to the body once ingested.

The technology of electrospinning drug delivery breaks with the limitations of the previous methods of encapsulation achieving a controlled, directed and even programmed administration in the body. These benefits are due to the variety of materials that can be processed by electrospinning and the structural variations of the capsules, creating a significant variety for drug delivery in the body. 

What is electrospinning

Electrospinning is a fibre manufacturing technique. It works with electromagnetic principles by subjecting substances to high voltages to generate an electrostatic charge in the material that ends up resulting in the formation of the nanometer fibre as a product of electrostatic repulsion and surface tension of the solution.

Electrospinning has several uses because of its property of being able to produce a great variety of fibres with significant differences from each other without changing the method. Although it was initially used for the manufacture of textiles has expanded to other areas such as the manufacture of batteries. Even combine the fibres with building elements such as concrete because of its high strength due to mechanical stress that is subjected to the material in its manufacture.

However, it is in the area of nanomaterial production where its maximum utility is highlighted since nanomaterials present particular interactions depending on the material, and it is at such scale where cellular processes occur. This reason is why medicine, more specifically pharmacology, benefits greatly from such technology. 

In pharmacology, two types of drugs are sold (differentiated by application according to the fibre), dressings and tissues, both of which can be manufactured with the production of fibres derived from electrospinning. 

Differences between electrospinning and other methods for drug delivery

Notable drug encapsulation methods include spray-drying, freeze-drying and emulsification, which are easily recognizable on sight since most consumer drugs are distributed in such presentations. Each one has his own characteristics that make it more suitable for one type of drug than another, and each one has its limitations.

These methods are based on the preservation and dosage of the drug. Such as freeze-drying, which is the procedure of preservation by cryodrying, or emulsification, which consists of mixing immiscible liquids. While such forms of encapsulation work efficiently to preserve the drug and deliver it to the body, their reach goes there. 

Electrospinning systems for drugs delivery work in two ways, by mixing the bioactive compound, i.e. the drug with the polymer solution before applying electrospinning or after the creation of the fibre by coaxial processing. This method allows the efficient supply of the drug’s API as it benefits from the surface-volume area due to the dependence on the surface area where the application of nanofibers is favoured. 

The drug release profiles are highly adaptable to various applications by varying the solution of the polymer with which the nanofiber is created and controlling its area and volume. This process will allow the distribution of drugs that are released in response to chemical stimuli even hours after they have been ingested, that target specific areas if created with magnetic components, and even facilitate their production on a large scale since the other methods find it difficult to produce them massively.Innovation in fibre production in the pharmacological area will create more significant and more efficient scope for the medication of many diseases, improving the treatment of the patient and increasing its effectiveness. Electrospinning technology admits a wide range of natural and synthetic polymers for processing, in turn, lowers production costs, allowing for greater distribution of medicines to various sectors of the population.

Published

on

Cleaning is very important to have a good health. Since the Coronavirus appeared in our lives, this practice is very essential for people. Washing your hands is very good for you and for people but public areas must be cleaned as well. For example, your workplace. But if your work is in a big building, how can you clean everything as soon as possible? Or what about hospitals? They are actually full with sick people.

Don´t worry. I have one solution for you. Industrial cleaning machines market growth strategies are everything that you and your business need. This new product uses a system of industrial ultrasonic cleaner at the same time that helps the environment. Some companies use this technique since a lot of years because is very effective in cleaning efficiency. Now, I am going to explain to you some concepts about that. For example:

Why industrial cleaning machines are important to you

Industrial cleaning is a hard work. When you move around the same place that a lot of people, the public areas need stay clean. Everything must be cleaned every time to avoid to get the virus but it´s difficult that workers do this hard work.

They need be helped by the machines which have developed last years. The most important thing about the evolution is the industrial cleaning machines are made thinking about environment.

Effectiveness and respect for the environtment are the best qualities than they have wanted to prove because the health is the most important thing for the world population.

One recent investigation has concluded that industrial cleaning machines are very important to the future. Experts think that we are in front the best market trend in recent times. The investigations include a lot of countries which have some strategies to grow the market in the next five or six years maximum.

Industrial ultrasonic cleaner

Ultrasonic technology is kind to the environment. Apart from this, industrial ultrasonic cleaner gives the best methods of the market respect to others competitors. That means good advantages because their methods are safe and confidence for the customers. These machines are suitable for cleaning hospitals, medical tools or whatever other area from health.

If hospitals are full for Coronavirus or other pathologies, cleaning is essential. Industrial ultrasonic cleaner can be high-power (HPU) or low-power. The first create submicroscopic vapor bubbles which disperses and contract. The temperature and pressure go up and then particles are released entirely. This process guarantees good results because, thanks to deep clean, the machine is able to eliminate the dirt lodged in the pieces, even in places with difficult access. However, industrial ultrasonic with low power only can clean objects like jewelry or medical instruments. Save money and time, quality higher cleaner, support the environment because they use little laundry soap and water, they use automatic system are some advantages to have industrial cleaning machines. So it´s very helpful for you business and it´s very good for your life.

Practical Steps To Become A Critical Care Nurse

Published

on

Being a critical care nurse is a very rewarding job, but before finding open jobs in critical care, it would be best to know the practical steps you can take to become a critical care nurse. There is a process you must go through before you can start practising. You will be treating patients with all kinds of ailments from life-threatening injuries to medical issues. It is important that you are well-equipped to handle anything that may come your way. Here are some practical steps to take to become a critical care nurse.

Earn A Bachelor’s Degree In Nursing

Getting a degree in the science of nursing is the first step you can take to become a critical nurse. While getting your bachelor’s degree you will be learning the principles of nursing. You will develop your critical thinking skills as well as your ability to problem-solve while you learn things like anatomy, nutrition, microbiology, public health, health assessment, physiology and evidence-based practice. Your bachelor’s degree will give you the necessary foundation needed to pick up a speciality. You will also be able to get an up-close and personal look at the day-to-day functions of a nurse. This will help you determine if this is the right career path for you at the start.

Pass Your National Council Licensure Examination

Now that you have earned your bachelor’s degree, you now have to pass your national council licensure exam. This exam is required if you wish to be a licensed nurse practising in the United States. The exam tests your knowledge and retention of the nurse foundations you learned while in school. It is divided into four categories that cover a range of topics like physiological adaptation, reduction of risk potential and physiological integrity just to name a few. Once you pass your exam, it is required that you work a minimum of two years. To be a critical nurse, you should focus your clientele on families, geriatrics, adults and children.

Earn Your Master’s Degree From An Accredited MSN Program

You could always stop after you earn your bachelor’s and you become licensed, but if you want to advance this is the next step. Make sure that your MSN program focuses on critical care or ICU nursing. In addition to studying, you will learn both evidence- and theological-based concepts. The goal would be to build upon the foundation you already laid in undergraduate school. This extra step just allows you the time to learn key skills that you can perform immediately after graduating.

Get Certified as a Critical Care Nurse by the American Association of Critical-Care Nurses

This is another step that will really set you up for advancement within this career track. Getting certified by the American Association of Critical Care Nurses will help better establish your understanding of caring for someone who is critically ill or injured. There are also several specializations you can be certified in. One thing to note is that the certification is good for three years and it has to be renewed every three years.

How COVID is Changing Global Migration

Published

on

covid 19 coronavirus

The COVID-19 pandemic has changed the way we live. Whether it’s working from home, socializing virtually rather than face-to-face, or spending more time indoors, everyone’s lives have altered since the outbreak of novel coronavirus in late 2019.

One of the biggest changes to our way of life has been travel and transportation. As air, rail, and road travel became safer and cheaper, people routinely traveled from one country or continent to another. In many cases, people relied on these fast forms of transport to facilitate major lifestyle changes, such as emigrating to a different country.

Due to COVID-19, however, the transport industry ground to a halt. In a bid to slow the spread of the virus, airlines stopped flying, trains were halted and even journeys by road were actively discouraged or banned.

Has Migration Been Affected?

On a practical level, COVID-19 has affected migration simply because people have been unable to travel as easily as they normally would. With many countries closing their borders and imposing national lockdowns earlier in the year, there was simply no way for people to enter or leave certain jurisdictions. Even if a country’s borders remained opened, the difficulty in accessing international travel meant that people were largely unable to reach their intended destination.

Although many countries have now re-opened their borders and transport companies are re-started their services, we certainly aren’t ‘back to normal’. On-going quarantine regulations and travel restrictions mean that many people are unable or unsure whether to travel to another country at this time.

In addition to this, the economic impact of COVID-19 means that a significant number of people are concerned about finding work. If your ability to migrate depended on being able to find work, for example, the economic effects of COVID-19 are likely to have thrown your plans into disarray.

Conversely, the availability of work could affect patterns of future global migration. If industries in one country are decimated due to COVID-19, for example, a greater number of people may emigrate in order to find work. Currently, migration in Australia shows that the majority of immigrants settle in New South Wales. However, if future immigrants move to Australia to find work, they may settle in Western Australia, Queensland, or Victoria at higher rates if more work is available.

Will Migration Affect Global Poverty?

Migration has a major impact on poverty worldwide. In developing countries, for example, families often rely on funds being sent from loved ones who have migrated in order to find work. If this migration is prevented, as it has been due to COVID-19, then millions of people will be financially affected. As a result, the number of people living in poverty will inevitably increase.

At the same time, the wealthy have continued to make significant profits during the crisis. While some industries have been brought to a standstill, this hasn’t prevented the 1% from continuing to generate billions. With the economic and practical impact of COVID-19 worsening poverty, global inequality will, therefore, continue to rise.

Are People More Vulnerable?

When migration is prevented, people are increasingly vulnerable. Every year, hundreds of thousands of people migrate due to concerns for their safety, for example. Alternatively, they may be forced out of their homes, towns, and countries due to political instability or threats of war. If they are prevented from accessing a safe jurisdiction to border closures, this renders them stuck in an unsafe environment. As this presents a very real threat to lives, it’s clear that COVID-19 is putting people at risk in a myriad of ways.

Furthermore, the help that has previously been available to migrants is being drastically reduced. With countries investing heavily in industries and being forced to supplement the income of a large number of citizens, the help that has previously been given to migrants simply isn’t forthcoming. Even when movement pathways are fully re-opened, the lack of support available to migrants will have a significant impact on their ability to migrate.

What Does the Future Hold?

The COVID-19 pandemic has been underway for nearly twelve months, yet it continues to be a serious health risk to billions of people. As governments and scientists battle to get it under control, we can expect the impact of the virus to continue for years, if not generations. With the economical, societal, and practical effects of COVID-19 likely to outweigh its risk to individual health, the only thing we can be sure of is that COVID-19 will have a significant impact on the future of migration, travel, and transport.
