भारतीय वैज्ञानिकों की नयी खोज : शरीर में कैसे तेजी से फैलता है डेंगू वायरस

addtop, TOP STORIES, विश्लेषण
डेंगू वायरस शरीर को संक्रमित करता है, तो सफेद रक्त कोशिकाएं इससे लड़ने के लिए सक्रिय हो जाती हैं। लेकिन, वायरस सफेद रक्त कोशिकाओं पर आक्रमण करके उन्हें भी संक्रमित कर देता है और वे वायरस को नष्ट नहीं कर पातीं। इस तरह वायरस मनुष्य के प्रतिरक्षा तंत्र को भ्रमित करके दूसरी कोशिकाओं को भी संक्रमित करने लगता है। सफेद रक्त कोशिकाएं लिम्फैटिक प्रणाली के जरिये प्रवाहित होती हैं, इसलिए वायरस पूरे शरीर में तेजी से फैलने लगता है। भारतीय वैज्ञानिकों की एक टीम के नेतृत्व में संयुक्त रूप से किए गए नये अध्ययन में एक खास प्रोटीन की पहचान की गई है, जो एंटी-वायरल साइटोकिन्स को अवरुद्ध करके मानव शरीर में डेंगू और जापानी एन्सेफलाइटिस वायरस को बढ़ने में मदद करता है। डेंगू और जापानी एन्सेफलाइटिस के उपचार के लिए प्रभावी एजेंट विकसित करने में यह खोज उपयोगी हो सकती है। आमतौर पर पूर्ण एंडोथीलियम परत वाली रक्...
Indo-Pak study reveals extensive arsenic problem in Punjab groundwater

Indo-Pak study reveals extensive arsenic problem in Punjab groundwater

TOP STORIES, राज्य
A new survey has shown that there is a major problem of arsenic contamination of groundwater in flood plains of Ravi river on both sides of the India-Pakistan border. The study covered 30,567 wells in 383 villages dotting along both sides of the border and it found that as much as 23 per cent of them had arsenic content higher than the limit set by the World Health Organisation. The problem appeared to be more severe on the Indian side. The researchers tested water samples from 13,000 wells from 199 villages on the Indian side and 17,567 wells from 184 villages on the Pakistan side. But the proportion of wells with higher level of arsenic was more in the Indian villages at 25 per cent. Water samples were tested using a portable field kit. Later a set of sub-samples was also tested in...
Two-rupee coin should be discontinued rather than one-rupee coin

Two-rupee coin should be discontinued rather than one-rupee coin

addtop, TOP STORIES, आर्थिक
It refers to media-reports that central government is going to discontinue minting of one-rupee coin because of high minting-cost of rupees 1.11. Any such decision is anti-consumer, and will tend to raise prices of many such commodities which are presently priced at rupee one. Minting-cost is one-time spent on a coin with extra long life. It is ridiculous that central government despite adverse opinion of Reserve Bank of India RBI re-introduced one-rupee note on 06.03.2015 which has high printing cost of much more than rupee one and a very short life only for bureaucratic-craze of having signature on the note which is signed by an officer of Secretary rank while notes of all other dominations bear signature of RBI governor. Central government and RBI should produce coins only in denomin...
Subsidy to encourage e-cars and levy on new cars to discourage: Other measures necessary

Subsidy to encourage e-cars and levy on new cars to discourage: Other measures necessary

addtop, TOP STORIES, आर्थिक
It refers to media-reports that central government is planning a heavy subsidy of rupees 50000 on purchase of e-cars while levying levy of rupees 12000 on purchase of new cars to discourage their sale. Both the steps are grossly inadequate to practically discourage sale of traditional cars driven by petrol and diesel. With procurement price of both petrol and diesel being almost same, diesel is priced cheaper because it is used in commercial vehicles. Production of diesel-driven cars is gross misuse of having price of diesel less than that of petrol. There must be a complete ban on production of diesel-cars. All cars must have engines capable of being driven by petrol and CNG both. To discourage production of bigger cars occupying more space in road and parking, GST, road-tax, insura...
99-percent items to be under 18-percent or lower GST-slabs: What about service-sector

99-percent items to be under 18-percent or lower GST-slabs: What about service-sector

TOP STORIES, आर्थिक
It refers to media-reports about lowering GST on many more items so that 99-percent items will be under 18-percent or lower GST-slab as yet other unneeded financial gimmick. It is not proper to reduce GST-slab on items of long-term use like air-conditioners, refrigerators etc because it is one-time payment. Lower GST-slabs are beneficial on items of day-to-day use. But government has never thought of lowering GST-slab on invisible service-sector where it needs urgent lowering from existing 18-percent slab to 12-percent. Such a high rate of GST-slab hurts badly those honest tax-payers where professional service-providers have to pay from their pocket heavy dose of 18-percent GST when those having availed service do not pay GST. For examples even government-departments and TV channels do ...
Malpractices of Banks in respect of credit-cards

Malpractices of Banks in respect of credit-cards

TOP STORIES, आर्थिक
Union government and Reserve Bank of India (RBI) should take note of malpractices of Banks in respect of credit-cards. Arguments put by Banks to have extra-ordinary interest-rate to overcome heavy cost in credit-card operation is in itself confessional for giving banks permission to levy ‘hidden charges’ to befool customers. Banks can instead levy charges on issuing and transactions made through credit-cards. Even credit-card statements are designed in a manner like ‘Minimum Amount Due’ to befool customers that they put themselves in heavy dose of interest-rate. Banks also resort to malpractice by deliberately not sending credit-cards statements to make customers defaulters forcing them to pay heavy interest-dose apart from penalty. Any shortfall in payment attracts penalty and interest...

Loan-waivers, subsidies and promises directly affecting economy must not be allowed as part of poll-manifestoes

Former Governor of Reserve Bank of India RBI Raghuram Rajan has very rightly raised concern of vote-catching gimmicks like loan-waivers for farmers which very adversely affect the economy and mute middle-class tax-payers, with farmers ultimately at loss by one-time advantage of availing gimmick loan-waiver. There must be a complete ban on such promises like subsidies, loan-waivers etc to be part of poll-manifestoes of political parties. Ultimate sufferer of such loan-waivers is mute category of middle-class tax-payer who has to bear burnt of additional taxes or cost-inflation due to deficit economy caused due to loan-waivers, subsidies or other schemes directly affecting public-exchequers. Even subsidy-system should be fast abolished in a gradual manner. Agricultural income over certain...
Simplify Income Tax procedure by merging TAN with PAN

Simplify Income Tax procedure by merging TAN with PAN

addtop, BREAKING NEWS, TOP STORIES, आर्थिक
Presently Income Tax Department provides two types of numbers namely Permanent Account Number -PAN, and Tax Deduction and Collection Account Number -TAN. While PAN is to be obtained for every tax-payer, TAN is a special number required only by those responsible for Tax Deducted at Source -TDS. Those required to obtain TAN number have to go through cumbersome procedure of filing TDS returns every quarter even though tax is deducted at source only say once in a complete year. Moreover there can be cases where TDS provision may required to be used only once in several years. It troubles very much to such TAN holders who are unnecessarily compelled to file TDS returns as nil every quarter. Even Income Tax Department has to spend much on staff and other overheads for managing those registered u...

She further asked me to approach Consumer Court in case I wished to challenge GoAir rules. If consumers are to approach consumer-courts for such petty matters and anti-public rules, ...

It refers to welcome Supreme Court order directing central government to make appointment-process of Central Information Commissioners CICs including the Chief transparent by putting list of applicants on website making clear service-conditions of CICs. Supreme Court has also directed to initiate appointment-process of other three CICs wherein presently the process is initiated only for appointment of Chief Information Commissioner and four more Commissioners because at that time there were only four vacancies at CIC with four more retired after wards in November-December 2018. But instead of further delaying and spending extra on the appointment-process, central government can better select all the eight new Commissions from the existing list of applicants by seeking appropriate direct...
