HMPV भाइरस के हो ?
HMPV (Human Metapneumovirus) एउटा श्वासप्रश्वाससँग सम्बन्धित भाइरस हो, जसले प्रायः बालबालिका, वृद्धवृद्धा, र कमजोर प्रतिरक्षा प्रणाली भएका व्यक्तिलाई प्रभावित गर्छ। यो Paramyxoviridae परिवारको सदस्य हो र प्रायः सामान्य रुघा जस्तो देखिन्छ तर गम्भीर अवस्थामा पुग्न सक्छ।

HMPV का लक्षण:
HMPV भाइरसका लक्षणहरू संक्रमित व्यक्तिको उमेर र स्वास्थ्य अवस्थामा निर्भर गर्दछन्।
सामान्य लक्षणहरू:
रुघा र खोकी
नाक बन्द वा बग्ने
गला दुख्ने
ज्वरो

गम्भीर लक्षणहरू:
श्वासप्रश्वासमा कठिनाई
छातीको दुखाइ
फोक्सोमा सङ्क्रमण (जस्तै, निमोनिया)
वायुमार्गमा सूजन (ब्रोंकियोलाइटिस)

संक्रमण कसरी हुन्छ?
HMPV भाइरस हावामा रहेका स-साना थोपाहरू (droplets) मार्फत मानिसबाट मानिसमा सर्दछ।

कसरी सर्छ:
संक्रमित व्यक्तिले खोकेको वा हाछ्युँ गरेको हावाबाट।
संक्रमित वस्तुहरू (जस्तै, टेबल, खेलौना) छोएर।

उपचार:
HMPV का लागि कुनै विशेष औषधि वा खोप हालसम्म उपलब्ध छैन। उपचार प्रायः लक्षणहरू कम गर्न केन्द्रित हुन्छ:

आफैं गर्न मिल्ने उपायहरू:
पर्याप्त आराम गर्नु।
तातोपानी वा झोलयुक्त पदार्थ पिउनु।
वायुमार्ग खुला राख्न स्टीम लिनु।

औषधि:
ज्वरो र दुखाइ कम गर्न प्यारासिटामोल।
गम्भीर संक्रमणमा चिकित्सकको सल्लाहअनुसार एन्टिबायोटिक प्रयोग गर्न सकिन्छ (दोस्रो संक्रमण रोक्न)।

गम्भीर अवस्थामा:
अक्सिजन थेरापी।
अस्पतालमा भर्ना गरी गहन उपचार (जस्तै, भेन्टिलेटर)।
रोकथाम:
हाछ्युँ गर्दा वा खोर्दा मुख छोप्नु।
बारम्बार हात धुनु।
संक्रमित व्यक्तिबाट टाढा रहनु।
प्रतिरोधात्मक क्षमता बढाउन स्वस्थ आहार लिनु।
यदि HMPV संक्रमण गम्भीर देखिएमा तुरुन्तै स्वास्थ्यकर्मीको सल्लाह लिनु आवश्यक छ।

भारतको बेङगालुरुमा Human Metapneumovirus को पहिलो case फेला परेको छ।
Be alert🙁🙁🙁🙁

An 8 month old baby in Bengaluru India has been diagnosed with the first known case of humanmetapneumovirus (HMPV).

, a respiratory virus affecting the lungs and airways, poses higher risks for young children, the elderly, and those with weakened immune systems.

Be Alert
सचेत रहनुहोला

चीनमा हाल मानव मेटाप्न्यूमोभाइरस Human Metapneumovirus (HMPV) का कारण श्वासप्रश्वास सम्बन्धी संक्रमणको संख्या बढिरहेको छ। यो भाइरस विशेषगरी साना बालबालिका, वृद्ध व्यक्तिहरू, र कमजोर प्रतिरक्षा प्रणाली भएका व्यक्तिहरूलाई प्रभावित गर्छ। यसले ज्वरो, खोकी, नाक बन्द हुने, र सास फेर्न गाह्रो हुने जस्ता लक्षणहरू देखा पार्छ। गम्भीर अवस्थामा, यसले ठूलो श्वासप्रश्वास समस्या निम्त्याउन सक्छ।

चीनका अस्पतालहरूले HMPV का कारण फ्लूजस्तै लक्षण भएका बिरामीहरूको संख्यामा वृद्धि भएको रिपोर्ट गरेका छन्। इन्टरनेटमा सार्वजनिक भएका भिडियोहरूमा भीडभाड भएका अस्पतालहरू देखाइएको छ, जहाँ इन्फ्लुएन्जा ए, HMPV, माईकोप्लाज्मा निमोनिया, र COVID-19 सहित विभिन्न भाइरसबाट पीडित बिरामीहरू उपचार गराइरहेका छन्। यद्यपि, अहिलेसम्म चिनियाँ अधिकारीहरूले आपतकाल घोषणा गरेका छैनन्।

HMPV एउटा सामान्य भाइरस हो, जसले विश्वभरि श्वासप्रश्वास सम्बन्धी समस्या उत्पन्न गर्दछ। यो भाइरस प्राय: जाडो मौसममा बढी सक्रिय हुन्छ। चीनमा यस भाइरसका केसहरूमा देखिएको वृद्धि मौसमी संक्रमणको सामान्य वृद्धिसँग मेल खान्छ। यसबाट जोगिनका लागि हात धुने, संक्रमित व्यक्तिहरूसँग नजिक नहुने, र भीडभाड भएका स्थानमा मास्क लगाउने जस्ता सावधानी अपनाउनुपर्छ। हालका लागि, HMPV को लागि कुनै विशेष एन्टिभाइरल उपचार वा खोप उपलब्ध छैन। उपचार मुख्यत: लक्षणहरूको व्यवस्थापनमा केन्द्रित हुन्छ।

यद्यपि HMPV का केसहरूमा वृद्धि उल्लेखनीय छ, यो अहिलेको अवस्थामा COVID-19 महामारी जस्तो विश्वव्यापी खतरा भने होइन। स्वास्थ्य अधिकारीहरूले यो अवस्थालाई नजिकबाट निगरानी गरिरहेका छन् र भाइरसको प्रसार रोक्नका लागि आवश्यक कदम चालिरहेका छन्।

China is currently experiencing a surge in respiratory infections, notably due to the Human Metapneumovirus (HMPV).This virus primarily affects young children, older adults, and individuals with weakened immune systems, leading to symptoms such as fever, cough, nasal congestion, and shortness of breath.In severe cases, it can cause significant respiratory issues.

Hospitals in China have reported an influx of patients presenting with flu-like symptoms attributed to HMPV.Videos circulating online depict crowded medical facilities, with patients suffering from various viruses, including influenza A, HMPV, Mycoplasma pneumonia, and COVID-19.Despite these reports, as of now, Chinese authorities have not declared a state of emergency.

HMPV is a common virus that circulates globally, often causing respiratory illnesses, especially during the winter months.The recent increase in cases in China aligns with the seasonal rise in respiratory infections. Preventive measures include practicing good hand hygiene, avoiding close contact with infected individuals, and wearing masks in crowded places.Currently, there is no specific antiviral treatment or vaccine for HMPV; management focuses on relieving symptoms.

It's important to note that while the rise in HMPV cases is notable, it does not currently pose the same level of global threat as the COVID-19 pandemic.Health authorities continue to monitor the situation closely to manage and mitigate the spread of the virus.

Zombie virus revived

जम्बी भाइरस पुनर्जीवन

वैज्ञानिकहरूले साइबेरियाको चिरकालीन हिमभूमिबाट ४८,५०० वर्ष पुरानो "जम्बी भाइरस" पुनर्जीवित गरेका छन्।

यो भाइरस अझै संक्रामक छ र जलवायु परिवर्तनका कारण हिमभूमि पग्लिँदा प्राचीन रोगाणुहरू वातावरणमा फैलने जोखिमलाई देखाउँछ।

यसले प्राचीन रोगाणुहरूका सम्भावित खतराबारे चिन्ता उठाएको छ।

प्लास्टिक खाने सुपरवर्म
Plastic eating superworms

अस्ट्रेलियाका अनुसन्धानकर्ताहरूले Zophobas morio नामको सुपरवर्मले पोलिस्टाइरीन (स्टाइरोफोम) पचाउन सक्ने कुरा पत्ता लगाएका छन्।

यी किराका आन्द्रामा रहेका सूक्ष्मजीवहरूको इन्जाइमले प्लास्टिकलाई जैविक रूपमा विघटन हुनसक्ने तत्वहरूमा परिवर्तन गर्छ।
यो खोजले प्लास्टिक प्रदूषण नियन्त्रणमा नयाँ क्रान्ति ल्याउन र रिसाइकलिङ प्रणालीमा सुधार गर्न मद्दत गर्न सक्ने सम्भावना छ।

प्राणीले त्यस्बेला मात्र सिक्दछ, जब ऊ सिकाइ सिक्न तत्पर हुन्छ ।
तत्परता नभई सिकाइको प्रारम्भ नै हुन सक्दैन ।







In his experiments, Thorndike utilized what is known as puzzle boxes to study how animals learn.

The boxes were enclosed but contained a small lever that, when pressed, would allow the animal to escape. Thorndike would place a cat inside the puzzle box and then place a piece of meat outside the box.
He would then observe the animal’s efforts to escape and obtain the food. He recorded how long each animal took to figure out how to free itself from the box.

Eventually, the cats would press the lever, and the door would open so that the animal could receive the reward. Even though first pressing the lever occurred simply by accident, the cats became likely to repeat it because they had received an award immediately after performing the action.

Thorndike noted that with each trial, the cats became much faster at opening the door. Because pressing the lever had led to a favorable outcome, the cats were much more likely to perform the behavior again in the future

new cancer drug

A group of researchers announced a medical miracle by all standards after they tried a new drug that, during clinical trials, caused the cancer to disappear completely in 12 colon cancer patients and did not return to them again within 6 months, in a precedent that is the first of its kind.
The researchers explained that the drug, scientific name Dostarlimab and trade name Jimperli, is produced by GlaxoSmithKline, an immune protein that stimulates the immune system to attack and eliminate cancer cells.

The researchers added that the treatment is not directed at colon cancer only, but for all types of solid cancers, such as uterine, breast, prostate cancer, and others, and more clinical trials are being conducted on different types of tumors on a larger scale.

And the Food and Drug Administration (FDA) announced that they are very excited about the new drug and are trying to speed up the steps for testing the drug so that they can provide it with approval as soon as possible.

The Food and Drug Authority revealed that the new drug will reduce the number of patients who need major surgeries, chemotherapy or radiotherapy, and this will become a great advantage for young patients because it will preserve their reproductive ability, which was negatively affected by the old treatment methods.

The Food and Drug Administration said that we are on the threshold of a new era at the moment when man will be able, with science, to overcome the most dangerous disease on earth.
