न्यूयॉर्क| वैज्ञानिकों ने पाया है कि विटामिन-डी प्रतिरक्षा कोशिकाओं के कारण होने वाली सूजन को कम करने का काम करता है, जो गंभीर कोविड-19 के दौरान प्रतिक्रियाओं के लिए प्रासंगिक हो सकता है। अध्ययन में एक तंत्र प्रदर्शित किया गया, जिसके द्वारा विटामिन-डी, टी कोशिकाओं के कारण होने वाली सूजन को कम करता है। ये प्रतिरक्षा प्रणाली की महत्वपूर्ण कोशिकाएं हैं और कोविड-19 के कारण होने वाले संक्रमण के प्रति प्रतिरक्षा प्रतिक्रिया के हिस्से के रूप में निहित हैं।
पर्डयू विश्वविद्यालय के नेतृत्व में टीम ने कोविड संक्रमित आठ लोगों के फेफड़ों की व्यक्तिगत कोशिकाओं का अध्ययन और विश्लेषण किया। उन्होंने पाया कि कोविड वाले लोगों के फेफड़ों की कोशिकाओं में प्रतिरक्षा प्रतिक्रिया का हिस्सा ओवरड्राइव में जा रहा था, जिससे फेफड़ों की सूजन बढ़ गई।
टीम ने तब जांच की कि वायरस पिछले अध्ययन में फेफड़ों की कोशिकाओं को कैसे प्रभावित करते हैं। साथ ही यह पता लगाया कि वायरस एक जैव रासायनिक मार्ग को ट्रिगर कर सकते हैं, जिसे प्रतिरक्षा पूरक प्रणाली के रूप में जाना जाता है।
पर्डयू विश्वविद्यालय में कंप्यूटर विज्ञान और जैव रसायन विभाग के सहायक प्रोफेसर माजिद काजेमियन ने कहा, सामान्य संक्रमणों में टी कोशिकाओं का एक सबसेट, टी कोशिकाओं का एक सबसेट, प्रो-भड़काऊ चरण से गुजरता है।
प्रो-इंफ्लेमेटरी चरण संक्रमण को साफ करता है, और फिर सिस्टम बंद हो जाता है और एंटी-इंफ्लेमेटरी चरण में चला जाता है। विटामिन-डी टी कोशिकाओं के प्रो-इंफ्लेमेटरी से एंटी-इंफ्लेमेटरी चरण में इस संक्रमण को तेज करने में मदद करता है। (एजेंसी)

When was the last time you ran after a bus or chased through the crowd to board a metro on your way to work? When did you last get to sit by the balcony at leisure and bask in the morning sun without having to worry about missing a Zoom call? These might seem like non-threatening changes in your life, compared to the other major changes imposed by the incessant lockdowns owing to the pandemic, but they could have a long-term adverse effect on the body and mind in the form of a Vitamin D deficiency.
Forced to stay indoors, people have become lethargic, put on weight, and developed various Vitamin deficiencies. With bare minimum exposure to sunlight, the main source of Vitamin D, we are risking our bone health and immune system. Vitamin D helps the body to function well by making the bones healthy, and strengthening the immune system; it is also known to prevent cancers, says celebrity nutritionist and founder of 'Fat To Slim', Sikha A. Sharma.
She explains the vitamin D deficiency in detail:
Importance of Vitamin D
Vitamin D plays a vital role in our body by keeping one away from health issues like heart diseases, hypertension, diabetes, bacterial infections, immunity disorder, rapid-ageing, some types of cancers and multiple sclerosis.
Symptoms of Vitamin D Deficiency
Initially, Vitamin D deficiency does not show any notable symptoms, but acute deficiency may cause muscle cramps, backache, fatigue and depression and sleep disorder among several other disorders.
Getting Enough Vitamin D When Homebound
Sun exposure is the best source of Vitamin D. One must try to soak in the early morning at least twice a week for about 15 to 20 minutes.
There are various food items rich in vitamin D like -- cod liver oil, coriander, orange, yoghurt, cheese, garlic, dark chocolate, black mustard seeds, mushrooms, turmeric, and Kashmiri garlic -- which can help one boost their immunity naturally.
One can also take Vitamin D supplements available at medical stores, however, it is advisable to consult a physician before consuming medical supplements.
Consumption of Vitamin D Rich Foods
Have two cloves of garlic or 4-5 cloves of Kashmiri garlic early in the morning on an empty stomach, and after dinner. A tiny bit of dark chocolate once a day is also a good source of Vitamin D.
Having mushrooms once a week will help balance vitamin D levels in one's body. One should try and include bajra or ragi roti in meals as well, to quicken the process of upping the vitamin level. Consumption of black mustard seeds and half a tablespoon of turmeric powder are helpful to boost vitamin D levels.
Can Too Much Vitamin D be Harmful?
Strangely enough, one cannot get too much Vitamin D from the sun but can overdo the supplements causing various problems. Vitamin D toxicity is, thankfully, quite rare but it can lead to hypercalcemia symptoms of which are: nausea, increased thirst and urination, and poor appetite.
Fret not, and try to lead a more natural way of life by eating seasonal foods and home-cooked meals, and being active in day-to-day life. These simple practices will keep the body and mind fit.

Chandigarh, July 5 (IANS) Vitamin D, which is primarily related to bone and mineral metabolism, has shown promising results in COVID-19 treatment, said doctors of the PGI Hospital here on Monday.
But they warned against the use of its high doses, especially injectable preparations, to prevent the virus.
Summarising the available clinical evidence, the doctors at the Postgraduate Institute of Medical Education and Research have published a study in the Journal of Endocrinological Investigation entitled "Vitamin D supplementation and clinical outcomes in COVID-19: A systematic review and meta-analysis".
The study was conducted by Rimesh Pal, Mainak Banerjee, Sanjay K. Bhadada, Anirudh J. Shetty, Birgurman Singh and Abhinav Vyas.
"Pooled data from 13 studies showed that vitamin D supplemented after the diagnosis of COVID-19 leads to improved clinical outcomes in terms of reduced mortality and/or intensive care unit admission," Prof Sanjay K. Bhadada, PGI's Head of Endocrinology Department, told the media.
The study lends ample support to the fact that vitamin D can be used as an effective adjuvant treatment modality in patients hospitalised with COVID-19. The anti-viral and the immunomodulatory role of vitamin D are perhaps helpful in this regard.
Nevertheless, the irrational and rampant use of vitamin D to prevent COVID-19 should not be a norm.
"The use of vitamin D in high doses, especially injectable preparations, to prevent COVID-19 should be strongly discouraged. Vitamin D, supplemented prior to the diagnosis of COVID-19, was not found to improve clinical outcomes in our meta-analysis. Instead, overuse can lead to vitamin D toxicity," added Bhadada and Rimesh Pal.

Whether you are a skincare fanatic or have just started your journey towards creating your own beauty regime, you would have come across a multiplicity of ingredients on skincare product labels that often leave you wondering what's a good fit for you. The most versatile yet tricky amongst those is Vitamin C.
Most people get a fair dose of this vitamin from the food, fruits, and vegetables they eat. It is a legendary supplement required to keep our immune system robust and fortify our bodies against diseases. It has also played a crucial part in our fight against Covid-19.
With countless benefits internally, the vitamin has equal, if not more, dermatological advantages. Arushi Thapar, Senior Marketing Manager, Plum, PurePlay Skin Sciences Pvt Ltd. shares more on the new 'in' natural additive.
C the advantage! : Vitamin C is a potent antioxidant that can neutralize free radicals, but what does that mean for your skin? Vitamin C is known to be a difficult ingredient to develop and work with owing to its fragility and photosensitivity. With advancements in research, we know that the potent L- Ascorbic acid or also known as the most stable form of Vitamin C which can effectively reduce dark spots, protect from sun damage & treat dull skin.
With age and due to sun exposure, collagen synthesis in the skin decreases, leading to wrinkles- once again Vitamin C is the only antioxidant proven to stimulate the synthesis of collagen, minimize fine lines, scars, and wrinkles. Therefore, its important to understand the make of such a potent concoction with multifold benefits. Many skincare products on the market today, deep dive into the skincare science and highlight the vitamin C derivatives, which is an important part for consumers to understand and choose the right Vitamin C serum. Products with the right concentration, formulation and other mix of ingredients like Japanese Mandarin and Kakadu plum that boost the performance of the Vitamin C, are important factors to take into consideration before purchasing a Vitamin C serum.
Why Plum Mandarin & Vitamin C serum should be your holy grail: Make sure your Vitamin C serum checks these boxes before purchasing or using them.A greater absorption of skin is possible with the use of vitamin C in serum-based formulations. The concentration should be between 10-20% with the sweet spot at 15%- any higher nullifies the benefits and could damage your skin. Another important aspect to pay attention to is the pH value. Human skin tends to have a pH value between 4-5 hence, the serum should have a similar value to be effective.
Other factors to consider while adding Vitamin C to your beauty shelf include packaging, colour, and smell. As mentioned before, Vitamin C is photosensitive i.e its properties change with exposure to light. It is, therefore, important for the serum to be packaged in a dark or amber coloured bottle. Store away from sunlight and in a dry environment. Be mindful of the colour and smell- ideally any skincare product should be free of artificial colours & fragrances. A change into a yellow, orange, or brown colour means it has oxidised; a sour or rancid smell means the product has lost stability and its use must be discontinued.
Once you have the ideal Vitamin C infused serum you can mix it up with your existing AM/PM regime- As a base alongside sunscreen is basic but an absolute must-have for glowing skin. It can also be used with Hyaluronic acid for hydration; combined with peptides making it a specialist for mature skin, or mixed with Vitamin E for ultimate nourishment for your skin! Ingredients such as niacinamide, chemical exfoliants, and retinol should not be applied together. Vitamin C with Niacinamide could be potent, with exfoliants causing destabilization, and combined with retinol becomes too much for the skin to handle at one time.
Now that you know all there is to know about Vitamin C, add one to your cart that suits your skin the best. Go ahead, #CtheGlow for yourself!
