🦶Skin fissures :- These are areas of dried, cracked skin that thicken over time. They appear as tiny cuts or cracks in the skin. The surrounding skin is usually thickened and calloused. They most often occur on very dry areas of the skin like the heels, fingertips, and between the toes.
🤔 Causes:- Cracked skin always begins as dry skin. As the skin becomes thick and calloused over time, it loses elasticity, and tiny cracks form. Left untreated, these cracks can deepen and lead to bleeding and infection.
❄️ Weather: Living in a cold, dry climate can be drying to your skin and raise your risk of skin fissures.
🫴 Overuse: Any area of skin that is continually used or washed is at a higher risk of becoming dry.
💦 Water exposure: Frequent exposure to water, such as handwashing, can dry out your skin and raise your risk of experiencing eczema and cracking.
🥗Nutritional deficiencies: Vitamin deficiencies can lead to dry, itchy skin that does not heal as quickly as healthy skin.
🧴Treatment:- you can apply Humectants (glycerine ,urea) , Occlusives (bee wax, mineral oil), Emollients, Emollients like lanolin and propylene glycol linoleate act as lubricants that fill in the crevices between skin cells.
Home remedies to keep skin moisturized , you can apply olive oil, coconut oil, Avocado oil, Oat Oil, almond oil etc.

How ultrasound works
Ultrasound or sonography is a method based on the principles of echolocation. The very first ultrasound machines were used in veterinary medicine to determine the thickness of subcutaneous fat in pigs. The first use of ultrasound for human examination dates back to 1942.
The gel that is applied to the skin creates a sound-conducting environment and eliminates air between the skin and the machine, reducing noise. The transducer, in turn, transmits high-frequency sound waves that reach the object, are reflected from it and displayed in the receiver. And the receiver converts them and displays them on the monitor. In fact, the picture consists of dark and light spots, but a qualified specialist, guided by their shape and location, can judge about the studied organ.
Modern ultrasound machines are more functional and technologically advanced, and allow you to obtain a three-dimensional image of the examined organ.

➕ 10 essential Medicines to Keep at Home
✏️Paracetamol 👉 It is commonly used OTC medication for fever, minor aches, and pain.
✏️Antacid 👉 If an individual experiences heartburn or pain or bloating, it is likely that the digestive acids present in the stomach are causing the problem. In such a case, an antacid can be taken to neutralize the harmful effects of acid and aid digestion.
✏️Antihistamine 👉 Avil and Cetzine are two commonly available antihistamines that can be taken to ease the symptoms caused by allergic reactions. It is important to note that these tend to cause mild drowsiness.
✏️Nasal decongestants 👉 Nasal congestion is one of the most common symptoms of cold and sinusitis. To relieve the stuffy or congested nose, OTC medicines such as nasal decongestants can be taken.
✏️Antitussive lozenges 👉In most cases, a cough or a cold is accompanied by itching or sore throat. Although the intake of antibiotics can help relieve the underlying infection, it is also essential to use medications that can relieve discomfort in the throat.
✏️Antiseptic ointment 👉 The ointment or solution can help prevent any minor scrapes, wounds, or cuts from getting infected with bacteria or other microorganisms. Example - Dettol and Savlon
✏️Antifungal medications 👉 These used to treat fungal infections that affect skin, hair and nails. Some of the common fungal infections are ringworm, athlete's foot, candidiasis, vaginal thrush, etc. Antifungal medications work by directly killing fungal cells or by preventing fungal cells from growing and thriving.
✏️Anti-sickness medications 👉 Anti-sickness medications such as domperidone and meclizine hydrochloride help in preventing and treating nausea and vomiting. These medications work by blocking the action of histamine, which can otherwise trigger the feeling of being sick.
✏️Topical ointments for burns 👉Ointments containing silver nitrate, amorphous hydrogel, silver sulfadiazine, or aminacrine HCl help in treating minor, first-degree burns that affect the outermost layer of the skin. These medications have antimicrobial properties, which exacerbate the healing and prevent further infection.
✏️✏️Aspirin 👉 Aspirin, or salicylic acid, is one of the most well-known OTC medications for aches and pains. It is also sometimes used to get relief from inflammation, cold, and fever. Owing to its anti-blood-clotting properties, the medication is also one of the first-line emergency treatments for heart attack and stroke.

Cataract or glaucoma
Cataracts and glaucoma are eye diseases that cause decreased visual acuity. For this reason, most people often confuse these diseases. Let's get to the bottom of this!
Cataract is a clouding of the lens of the eye. The disease is most commonly diagnosed in elderly patients, but can develop at any age. The change in the transparency of the crystalline lens can be so severe that it leads to complete loss of vision. An effective method of treatment is surgery to replace the crystalline lens with an intraocular lens.
Glaucoma is a complex of pathological changes accompanied by an increase in intraocular pressure. The pathology is treated with eye drops, which improve the outflow of the intraocular fluid and decrease the pressure on the eye nerve. Compared to cataract, glaucoma is associated with irreversible vision loss. Surgery is indicated only when drug therapy fails to maintain eye pressure in the normal range.

Why don't people wake up from their own snoring?
Since even in sleep the brain analyzes sounds, and the sleeper wakes up if the sound is unexpected or has a signal meaning (call, name calling). A person may also be awakened by the absence of a sound, for example, if a night train, which constantly passes by his house at the same time, for some reason did not pass by.
At the same time, the loud but familiar noise does not bother the person, which is known to anyone who has fallen asleep in the subway. Here, too, the snorer's brain does not perceive snoring as an unexpected sound.

Premaram becomes first Asian to undergo total arm transplant at Mumbai hospital
33-year-old Prema Ram from Rajasthan's Ajmer became the first man in Asia to undergo a total bilateral arm transplant. Premaram lost his both hands in an electric accident a decade ago. The feat, a medical milestone for India, was achieved by a team of doctors in Mumbai's Global Hospital who performed a 16-hour grueling surgery.
Previously, a bilateral total arm transplant was done in Europe, and this is the first bilateral total arm transplant in Asia. Doing a hand transplant at such a proximal level is very challenging. It is a race against time. During the procedure, timing and coordination are important so that limbs are attached to the body as early as possible so that blood circulation begins immediately due to a large number of muscles being transferred. Doing the similar surgery on both sides adds up to technical and logistical challenges.

WHY do wounds itch when they heal?
The injured tissue releases the neurotransmitter histamine abundantly. Immediately after injury, it triggers an inflammatory response and later prompts tissue stem cells to migrate to the damaged area and repair the tissue.
It turns out that histamine irritates the nerve endings in the skin, causing itching.

WHY are there many drugs against bacterial infections and few against viral ones?
A bacterium is an integral single-celled organism which biochemistry is quite different from that of humans. Therefore, it is possible to find drugs that block the enzymes vital for bacteria or destroy their cell wall, while being harmless or minimally toxic for humans.
A virus, on the other hand, is much simpler, and after infecting the target cell, it has nothing of its own except for the genome. Genome duplication and synthesis of viral proteins are performed by the same molecular mechanisms of the infected cell that ensure the vital activity of healthy cells.

Blood under the microscope 🩸🔬
The red color of human blood comes from iron inside the red blood cells. Iron is a very important part of the protein responsible for carrying oxygen, called hemoglobin. Each red blood cell is filled with these proteins and is ideal for transporting oxygen from the lungs throughout the body, like microscopic oxygen buses.

Physical activity improves mental performance
Physical activity improves recovery from stress and creates conditions for neurogenesis:
The following proteins are produced in the body during physical activity and are involved in recovery processes:
- Insulin-like growth factor-1 (IGF-1)
- vascular endothelial growth factor (VEGF)
- Fibroblast growth factor (FGF).
All of these increase our brain's working potential. Scientists are still working on how to develop creativity through physical activity, identifying the most effective ones. However, there are already precedents. It is known, for example, that the theory of relativity was born in Einstein's head while riding a bicycle.

WHY is it better to breathe through your nose in the cold?
The nasal cavity has the ability to raise or lower the temperature of inhaled air. As an example, if you run cold water through a hot pipe, after a while the water will warm up. It is the same with air. This nasal breathing makes the air temperature in the nasopharynx only 1-2 ° C different from the body temperature (36.6 ° C).
Even when it is -25° C outside, the air in a person's nasal cavity heats up to +35°-36.6° C in a matter of seconds.

How exactly does the Sun provide us with Vitamin D?
It is a myth that sunlight provides us vitamin D or vitamin D is present in sunlight.
The fact is vitamin D is synthesized in plants, animals and humans in presence of sunlight.
There are two types of vitamin D - vitamin D2 (Ergocalciferol) present in plants including ergot and mushrooms and vitamin D3 (Cholecalciferol) in animals.
Vitamin D2 (Ergocalciferol) and vitamin D3 (Cholecalciferol) are synthesised in presence of ultraviolet light (UV) of sunlight as given below.
In plants, the ergo-calciferol (vitamin D2) is derived from UV irradiation of ergosterol (a kind of sterol present in plants).
In animals and humans, when skin is exposed to sunlight, chole-calciferol (vitamin D3) is produced in skin by UV irradiation of 7-dehydro-cholesterol (a kind of cholesterol present in animals and humans).
Sunlight triggers the first of three chemical reactions that converts an inactive compound in the skin into active vitamin D. Ultraviolet B rays from the sun convert a natural vitamin D precursor present in your skin, 7-dehydrocholesterol, into vitamin D3. This travels to the liver where the addition of oxygen and hydrogen to vitamin D3 changes it into 25-hydroxyvitamin D. Doctors test for this intermediate and still inactive form of vitamin D in blood to determine your vitamin D status. Final activation of 25-hydroxyvitamin D takes place in the kidneys, where more oxygen and hydrogen molecules attach to 25-hydroxyvitamin D and convert it into its active form known as 1,25 dihydroxyvitamin D, or calcitriol.

Black pox
Smallpox is one of the oldest and most terrible diseases. The first outbreaks of the disease were recorded even before our era.
The causative agent of smallpox is Variola virus, which is transmitted from person to person. The main sign of the disease is the appearance of blisters filled with black fluid. The rash spreads quickly throughout the body and can affect the outer and inner mucous membranes. In place of the blisters then form open wounds, which easily "settle" different infections. Treatment is symptomatic, but complete isolation of the patient is mandatory.
The last case of smallpox was recorded at the end of the last century. But the virus that causes the disease still exists and is a biological weapon.

Where are our memories stored?
Memory in the brain is decentralized. In addition, remembering is not a fully understood process.
Memory data is distributed in a complex and intricate synaptic network.
Each fragment of a memory (a word, a view, a feeling) is encoded in the area that created it (temporal or occipital lobe, limbic system) and is activated each time it comes to mind.
There is information that the limbic system is responsible for long-term memory, but it is not the only one. It is accurate to say that memories are scattered throughout the brain.

What foods are good for your bones?
To keep your bones in great condition, you should enrich your diet with these foods:
1. Dairy products. Milk, hard cheeses, yogurt, and cottage cheese are the main suppliers of calcium. They also contain vitamin D, which helps this element to be absorbed.
2. Greens. Spinach, celery all types of cabbage. In addition to calcium, they are rich in vitamins B, E, and PP.
3. Fish. It contains vitamin D, phosphorus, and omega-3 fatty acids, which are necessary for calcium absorption.
4. Cereals and legumes. In addition to calcium, bones and joints need magnesium, which is found in wheat bran, cereals, and beans.
Magnesium, zinc, phosphorus, manganese, and copper should also be in the diet.

"Does tooth decay have nothing to do with sweets?"
The most common disease in the world is tooth decay. Naturally, there are many fabrications and misconceptions surrounding this disease.
So, my point is that it's not the carbohydrates themselves, but the time they stay in the mouth after eating - the small particles of food remain between the teeth.
- Sugar, sweet drinks, chocolate and some confectionery are quickly dissolved by saliva and washed out, but complex carbohydrates take longer, so right in the mouth begins to break them down.
Not only salivary enzymes are involved in the breakdown, but also microorganisms (their waste products are one of the factors of caries).
It turns out that tooth decay does not happen because we love chocolate and candy.

Why do drugs come in different forms?
Medicines are basically given based on their target organ and mode of action desired, so if one wants a medicine for stomach, it makes sense to give a tablet which can then directly go to stomach and act. This works if you have direct access to the organ desired, like stomach, Intestines (especially large intestine through anal suppositories), mouth (through orally solvable tablets), skin (through ointments, lotions etc.). Problem occurs when you need drugs which act on organs you cannot directly have access to, like heart, Brain, small intestine, Pancreas, blood etc. For these we use different route of administration and special formulations like Capsules (which do not get disintegrated by gastric acids and can directly go to small intestine where they can dissolve and initiate their actions), Buccal or dermal patch (where you do not want immediate action but long lasting action) etc.
According to route of action:
1. If we need immediate action we use sublingual tablets, which provide almost immediate action in emergency cases like heart attacks, where nitroglycerine is given for immediate relief.
2. Oral route is the most preferred route if there is no emergency, its the one most comfortable and has the lowest cost but has other disadvantages like irritation of gastric mucosa, delay in onset of arrival and other unwanted metabolic reactions like drug being acted upon by intestinal enzymes. Different forms are Tablets ( It comprises a mixture of active substances and excipients, usually in powder form, pressed or compacted from a powder into a solid dose), Capsules (where the drug is enclosed in a gel like covering allowing it to pass the barriers like stomach acids and be used as anal suppositories, also liquid form of drugs can also be given as capsules), syrup ( not much difference but some drugs are more active in liquid form, and sometimes its more comfortable like in case of children)
3. Topical: By delivering drugs almost directly to the site of action, the risk of systemic side effects is reduced. However, skin irritation may result, and for some forms such as creams or lotions, the dosage is difficult to control as it depends on the person applying the lotion/cream.
4. Inhalation: Inhaled medications can be absorbed quickly, and act both locally and systemically. Proper technique with inhaler devices is necessary to achieve the correct dose. Some medications can have an unpleasant taste or irritate the mouth. Inhalation by smoking or inhaling a substance through inhalers is likely the most rapid way to deliver drugs to the brain, as the substance travels directly to the brain without being diluted in the systemic circulation and effects are more potent. eg Cigarette smoking
5. Injection: The term injection encompasses intravenous (IV), intramuscular (IM), and subcutaneous (SC) administration. Injections act rapidly, with onset of action in 15-30 seconds for IV, 10-20 minutes for IM, and 15-30 minutes for SC. They also have essentially 100% bioavailability meaning all drug injected goes directly into system, this can be used for drugs that are poorly absorbed or ineffective when given orally. Some medications, such as certain antipsychotics, can be administered as long-acting intramuscular injections. Ongoing IV infusions can be used to deliver continuous medication or fluids. Disadvantages of injections include potential pain or discomfort for the patient, and the requirement of trained staff using aseptic techniques for administration. @Health
