Anyone who has ever been called to come and speak or perform in front of a public gathering knows the importance of holding nerves.
From the time we are in school, some of us have dreaded raising our hands and speaking out the right answer even though we know what we are.
We have looked at astonishment at so-called confident individuals and wondered what makes them do things that we cannot.
Common terms like ‘performance anxiety, ‘stage fright’, ‘nervousness’, etc. are all common emotions and feelings that we harbor. The key is- how do we overcome the same?
In this resource article, we are going to help a lot of people come to grips with their nerves. If you are someone who dreads talking in front of a crowd, we recommend that you stick around till the end of the article.
Being ‘Nervous’ Versus Being ‘Excited’- How a Change in Terms Can Help:
‘I am too nervous; I can’t go out there and speak’!
According to leading psychologists, a simple interchanging of the terms nervous and excited can go a long way in dispelling the fear.
Rather than say or think that you are getting the nervous try and say to yourself that you are feeling excited. What you need to understand is that nervousness is associated with being a negative feeling. On the other hand, excitement is something that is deemed to be positive.
This simple exercise wires your brain in a specific way, which then lets the body flow from the same feeling. For example, as soon as your brain starts comprehending that you are nervous, it sends a signal to your body, which then results in stomach pains and churnings.
This is why you need to start feeling excited and look forward to the opportunity. There is a lot of energy that builds up in the body in such situations. The key is to effectively manage the same productively and positively.
The ‘Fight’ and ‘Flight’ Instinct that Defines a Nervous State of Being:
To understand these better leading scientists have spoken about the ‘Fight and Flight Syndrome’. They point out that whenever the brain is faced with a complex and problematic situation, it does one of two things-
It either wants to escape and run away from the scenario. Or,
It starts to swing madly to bring the situation under control.
However, in some instances, and I am sure, you are going to relate to this, the brain goes into a hung position. Meaning, it neither fights nor flights. In this situation, the resultant action is a freeze! You get frozen and cannot do anything.
According to experts, the fight or flight instinct needs to be properly managed by telling your brain some important things. What are those things?
In very simple words, not every such scenario is going to be a life and death one. Meaning it is not at all serious and does not amount to anything. Once your brain can understand this, it starts processing emotions and feelings differently. Following this, it then sends these signals to the rest of your body.

Oral cancer is one of the most common cancers worldwide. It can affect the mouth, tongue, gums, and throat. In fact, there are several factors that contribute to its development. These include tobacco use, excessive alcohol consumption, prolonged sun exposure, and infections like HPV.
However, early detection plays a crucial role in increasing the chances of successful treatment. Also, it helps in improving outcomes. In this article, you will get details about the early signs of oral cancer and what you should be mindful of. Hence, to learn more, read on to the end of the article.
What Is Oral Cancer?
Oral cancer is one of the most common forms of neck/head cancer. Generally, it affects people above 60 years of age. In fact, oral cancer first affects your lips, tongue, mouth roof, and mouth floor. Apart from that, it also affects your oropharynx, which is the last part of your tongue. Also, it might affect the roof of your mouth, the sides and the back of your throat, and your tonsils.
At first, oral cancer can look like a common problem in your mouth and your lips. For instance, you can see white patches or bleeding sores. Basically, the difference between a common problem and a potential cancer is that the problems do not go away.
Here, if you leave the problems without any treatment for a long time, it can spread through your mouth and your throat. Moreover, it will also spread to other areas of your head and neck.
8 Common Warning Signs of Oral Cancer You Shouldn't Ignore
Recognizing the early signs of oral cancer can significantly improve treatment outcomes. Here are eight common symptoms you must watch for and discuss with a cancer specialist promptly.
1. Presence of White/Red Patches in the Mouth
A classic sign of potential oral cancer is the presence of white or red patches in the mouth without any reason. Patches can occur on the tongue, roof of the mouth, inner cheeks, or gums. Patches can be painful sometimes but are usually asymptomatic.
However, you must not ignore them. If you see any of these patches extending more than a few weeks, visit an oncologist for a checkup at Apollo Hospital Belapur. Here, you will get a thorough examination.
2. Persistent Mouth Sores
Oral cancer can be indicated by mouth sores that do not heal within two weeks. The sores may be on the tongue, inside the cheeks, or gums, or on the roof of the mouth. However, getting sores in the mouth is quite common.
Still, you must let an oncologist evaluate sores that don’t improve. Don’t ignore the sores if they are painless or persistent. It could mean something more serious.
3. Difficulty Swallowing or Chewing
Pain or discomfort when swallowing or chewing food may be a sign of oral cancer. When there is a tumor blocking the throat or esophagus, difficulty swallowing or dysphagia often occurs. In some cases, this symptom may be accompanied by a feeling that food gets stuck in the throat or chest.
However, if this continues, it is important to see a specialist to help diagnose any underlying health issue early on.
4. Unexplained Bleeding
Unexplained bleeding on the inside of the mouth is a cause for concern. It could be blood in your saliva or while you brush your teeth. However, if there is any unexplained bleeding from the gums, tongue, or mouth, you must immediately visit a healthcare professional.
Apart from that, bleeding from your gums can be a sign of a minor gum problem. However, if it’s consistent or unusual, it could mean something more serious, such as oral cancer. If you are bleeding, don’t hesitate to visit the best oncologist in Mumbai to get it evaluated.
5. Numbness or Pain in the Mouth or Jaw
If you have numbness or persistent pain in the mouth or jaw that doesn’t go away with over-the-counter pain relief, don’t ignore it. This may mean that cancer is affecting the nerves in your mouth or jaw area. This pain can get worse over time and often comes with other symptoms, such as difficulty moving the jaw or feeling fullness in the mouth.
Hence, you must consult a medical expert. Basically, the expert can help in figuring out the reason behind it and suggesting reasonable treatment alternatives.
6. Unexplained Weight Loss
Sudden weight loss, especially if it is unintentional, can be a sign of a number of health conditions, including oral cancer. Cancer cells can interfere with your body’s metabolism, leading to weight loss.
Moreover, if you get sudden weight loss along with other symptoms such as mouth sores, pain, or difficulty swallowing, see a medical expert as soon as possible. Early diagnosis can enhance the prognosis and treatment options for oral cancer.
7. Changes in Voice or Hoarseness
If you find that your voice or hoarseness doesn’t go away, it could be because oral cancer is affecting your vocal cords or the area around them. If the hoarseness lasts more than a couple of weeks, it’s a good idea to consult an oncologist. Any change in voice should be evaluated to rule out any serious condition, including oral cancer.
8. Lumps or Swelling in the Neck
Signs that the cancer may have spread to nearby lymph nodes include swelling or lumps in the neck. At first, these lumps may be painless, but they can become tender as the disease progresses. If you see any lumps or swelling in your neck, you should see a doctor right away.
An oncologist will evaluate these lumps. Also, the expert will ensure an accurate diagnosis to find whether these lumps are cancerous.
Activities that Increase Oral Cancer
The following are some of the major activities that increase oral cancer:
Smoking (cigarettes, pipes, and cigars)
Other tobacco products include chewing tobacco, snuff, water pipes, dip, etc.
Drinking excessive amounts of Alcohol daily.
Spending a lot of time under the sun without protecting the lips.

Biochemistry reflects on the chemical compositions of living organisms. If in a science class one has encountered statements like the chemical composition of blood glucose is C6H12O6, then this lesson is part of biochemistry research that has found its way to textbooks.
Biochemistry also deals with chemical interactions between living cells. For instance, once we eat, the process of digestion that releases energy in the form of ATP and the chemical reaction involved in these metabolic activities are part of biochemistry.
The signals released by the brain in response to pain, how oxygen is used by blood cells, and the entire chemical process involved at the molecular level is studied as part of the biochemistry discipline.
A biochemistry course can be taken both as a specialization or an interdisciplinary course along with a related major or minor for challenging career prospects in life sciences. Interested students can check out this biochemistry course.
Scope And Uses Of Biochemistry
Biochemists hold numerous positions not just in the direct or ancillary healthcare sector but also in any field that involves food and nutrition.
Here are a few areas where biochemistry is used:
A. Nutritional science
The molecules like amino acids, lipids, fats, carbohydrates, and fiber constitute the macros of a balanced healthy diet. Biochemistry in food and nutrition deals with the process of generation and maintenance of the essential macros and glucose levels in a body. Any tipping in the readings will be the result of the body's chemical response to any underlying disease condition.
B. Genetic engineering
Genetic engineering is technically a branch of biotechnology. However, to understand DNA sequencing, chemical composition is necessary information. And hence biochemistry becomes an interrelated discipline for genetic engineering.
Biotech is widely used in understanding pathological specimens of microbes, and human, veterinary, and plant genes to help in combating diseases, creating resistant varieties of bloodlines in animal husbandry, and disease-resistant variants of plants.
C. Medicine
Pharmacological advances in new drug formulations, the development of vaccines, immunology, and pathology are some areas where biochemistry is widely used. Only through biochemistry, the rollout of Covid vaccine was possible.
Tips For Preparing For Biochemistry
Biochemistry is a vast subject that deals with humans, animals, and plants. It has other sub-categories like structural biochemistry, enzymology, xenobiotics, and organic and molecular biochemistry.
Considering the numerous topics, although the subject is interesting, studying for coursework can be daunting. But with a little bit of planning and learning hacks, preparing for biochemistry lessons can seem like a breeze for students.
Here are tips to prepare for biochemistry coursework:
1. Memorize The chemical sequence
Biochemistry is one of the least-liked subjects by many because of the many chain reactions and pathways that one needs to remember. The only way one can remember these chemical reactions is by logically grasping them, and then writing them down 2-3 times to memorize them. Once you have understood and memorized it correctly, write it backward. This step seals the content in your memory for a long time.
2. Revise important topics
Biochemistry is easy to forget a subject if you have not grasped the concept and memorized it. Topics related to organic biochemistry, lipid metabolism, amino acids secretion, enzymes secretion by glands like the pituitary and liver, the pentose phosphate pathway, and nucleotides need to be revised through notes revision, flashcards, and practice quizzes.
3. Study groups
Divide the biochemistry topics among members of study groups to make notes. In this manner, all the important topics can be revised easily by dividing the work related to notes and crucial points that form the framework of the lesson
4. Illustrate
Biochemistry is easy to remember when you use imagination and draw the reactions in a fun and easy-to-understand manner. You can always give character names to any of the molecules that are both easy to remember and relatable.
5. Focus on an essential topic
Divide the topics into the most repetitive and course-wise imperative ones. Divide your attention in an 80:20 ratio and give more importance to the core topics. In this manner, the regularly difficult topics are covered and repeated.
Twenty percent dedicated to other least important topics can be revised once. This way is ideal when trying to fit in a lot of work within a short timeframe. For instance, you can give more time to topics on metabolic and organic chemistry, enzymes, and pathways.
6. Comprehend
Biochemistry is a science subject and rote memorization alone can never work. The only way to retain it for a longer time comes from grasping the concepts and even memorizing them. If you can practice explaining the concepts to a five-year-old by following the Feynman technique, then the chances of you understanding the concepts are more.
7. Biochemistry terminology
All the terms used in this subject are different and some concepts will be completely new to you. Enzymes have suffixes like lyases, hydrogenases, oxidases, etc. A grasp on these terms by memorizing through mapping can help a student fare better
8. Structural biochemistry
Learning the chemical structure of molecules of chlorophyll, glucose, enzymes, amino acids, triglycerides and all other compounds within a living being will help biochemistry enthusiasts in their research as well
9. Organize study time
As the syllabus of biochemistry is an expanse, allotting a specific time and sticking to the schedule will help individuals gain confidence and have enough time to revise important topics before tests.
10. Take short breaks
When reading long topics and sequentially memorizing them, it is essential to take short breaks that can help a person rejuvenate and remember the lesson.
Conclusion:
Biochemistry is an important subject in medical school and some of the stem sciences. It is an essential subject in life science. There are a wide array of jobs that can be obtained with an education in biochemistry.
It is an important part of the med school program as well. Anyone interested in studying biochemistry can explore online Medtech platforms that will aid in improving the grasp through multiple immersive topics with animated illustrations.
