क्या मिलेगा अंधेपन से छुटकारा? 

फोटोरिसेप्टर रेटिना में उपस्थित वे कोशिकाएँ है जो हमारे देखने की क्षमता को प्रभावित करती हैं

जैव प्रौद्योगिकी पर किए गये एक शोध से पता चला है कि आँख का वह हिस्सा जो रोशनी को पकड़ता है, उसे अब स्टेम कोशिकाओं के ज़रिए ठीक किया जा सकेगा.

मूरफील्ड क्लिक करेंनेत्र अस्पताल एवं यूनिवर्सिटी कॉलेज, लंदन की टीम के मुताबिक पहली बार सच में इंसानों पर यह परीक्षण किया जा सकता है. विशेषज्ञों ने इसे एक 'महत्वपूर्ण सफलता' और आगे के लिए बड़ा कदम बताया है.

लोगों में फोटोरिसेप्टर कोशिकाओं को जीवित रखने के लिए स्टेम कोशिकाओं के प्रयोग का परीक्षण पहले से हो रहा है. लंदन स्थित टीम ने यह दिखाया कि रोशनी को ढूँढने वाली कोशिकाओं को बदला जा सकता है जिससे अंधेपन को दूर करने की संभावना बढ़ जाती है.फोटोरिसेप्टर रेटिना में उपस्थित वे कोशिकाएँ है जो रोशनी को यांत्रिक तरंगों में परिवर्तित कर मस्तिष्क में भेज देती हैं. हालाँकि ये कोशिकाएँ अंधेपन की कुछ स्थितियों में मर भी सकती हैं जैसे कि किसी गंभीर बीमारी के होने या उम्र के ढलने पर.

चूहों पर परीक्षण

फोटोरिसेप्टर रेटिना में उपस्थित वे कोशिकाएँ है जो हमारे देखने की क्षमता को प्रभावित करती हैं और उन्हे यांत्रिक तरंगों में परिवर्तित कर मस्तिष्क में भेज देती हैं.

उन्होंने बताया कि प्रयोगशाला में रेटिना को बनाने की नई तकनीक का प्रयोग किया है. इसमें हज़ारों स्टेम कोशिकाओं को इकठ्ठा किया गया जिन्हें क्लिक करेंफोटोरिसेप्टरकोशिकाओं से बदल कर एक अंधे चूहे की आँख में इंजेक्ट कर दिया गया.

अध्ययन में यह पता चला है कि इन कोशिकाओं ने पहले से मौजूद कोशिकाओं के साथ जुड़कर आँख में ठीक से कम करना शुरू कर दिया.

हालाँकि इसका असर अभी भी बहुत कम है क्योंकि लगभग दो लाख कोशिकाओं में से सिर्फ़ एक हज़ार कोशिकाओं ने ही वाकई में कम करना शुरू किया था.

मुख्य शोधकर्ता प्रोफेसर रॉबिन अली ने बीबीसी को बताया, ''अब इससे हमें मानवों में प्रयोग करने का तरीका भी मिल गया है. इसलिए हम बहुत ही उत्साहित हैं. पाँच साल से चल रहे इस शोध का चिकित्सीय परीक्षण करना अब हमारा लक्ष्य है.''

आँख का प्रतिरक्षी तंत्र बहुत कमजोर होने से भी इस प्रतिरोपण के खारिज होने के अवसर बहुत कम हैं. हज़ारों स्टेम कोशिकाएँ आँख की दृष्टि को सुधार सकती हैं जबकि इतनी ही संख्या में स्टेम कोशिकाएँ खराब लीवर जैसे बड़े अंग को दोबारा नहीं बना सकती. (Courtesy-BBC)

Teachers training and quality education.

Teachers training and quality education.

Boarding schools play very vital role for grooming the personality of child. But this grooming needs directional approach by teachers, housemasters and parents.

In boarding schools hyperactive children are much more as compared to day schools. The boarding schools of India has very good track record for bringing up many great personalities. Today boarding schools are facing the problems of lack of trained teachers/human resource. In India B.Ed colleges are not giving any precise training to pupil teachers about the working culture of boarding schools. It seems that education department and HRD ministry ignore the role of boarding schools in spreading the education.

Management of day school vs. boarding school, teaching skills, decentralization of powers, role of student council and school captains, emphasis on co-curricular activities in both type of schools are totally different.

 Teacher has to play dual role in boarding schools i.e. teacher as well as guardian. In India the quality of teachers are very poor because of low salary package as compared to other professions. Teaching is last option in front of youth of this country. Without proper training of teachers and not giving adequate salary the standard of education cannot be improved.Govt. along with private sector should come forward to improve the overall standard of education in India and to make India as developed nation in 21th century.

Time has come to rethink about the policy of education in India.Good quality and equal education should be a fundamental right to each citizen of this world.

TEACHING AND PREACHING

HOW TO CELEBRATE WED (WORLD ENVIRONMENT DAY)

5th June every year is celebrated as WORLD ENVIRONMENT DAY.Few years back I went to Mussoorie to attend a seminar on rainwater harvesting and environment conservation.Different speakers and officials have given long speeches for the protection of environment and to frame policies for environment conservationAt the end of this seminar snacks were served to us in plastic cups along with Pepsi.In the seminar the told not to use plastic cups but in real life they were using it.One of my student told me -Sir ,is this is the way to conserve the environment?I was speechless in front of the student.Sometimes small questions give us a sort of wisdom for  self introspection.Indian culture has a very rich traditional wisdom.This wisdom allows us to worship water,sun,moon,forests,animals and soil.Now in 21 century we are talking about green economy.Under the flowing wind of globalization we have done number of activities to degrade our environment.

As it is rightly said by Suderlal Bahuguna that Ecology is the real economy.We are least worried about the sustainable development.India and few other developing nations have become dumping ground for electronic waste.Now the time has come to say good bye to all these harmful practices and to adopt good practices.
