	(Sponsor this newsletter) सर्वश्रेष्ठ देहदान आपल्याकडे देहदान आणि अवयवदान या दोन गोष्टींबाबत आवश्यक तेवढी जागरूकता झालेली नाही. कित्येकांना तर अवयवदान आणि देहदान या दोन भिन्न गोष्टी आहेत याची कल्पनाच नाही. अवयवदान आणि देहदानाची ही माहिती. साधारणपणे मृत्यूबद्दल चर्चेला कोणी तयार नसतं. त्यात देहदान किंवा अवयवदानाबद्दल अनेक गैरसमजुती असतात. दररोज बेवारस प्रेतं खूप मिळत असतील, मग आपण कशाला देहदान किंवा अवयवदान करावं, दान केलेल्या देहाची?विटंबना होत नसेल, नोंदणी केली?तर दान घेणार नाहीत, एखादा अवयव दान दिला तर पुढील जन्म त्या अवयवाशिवाय मिळेल, ज्येष्ठ नागरिकांना यापैकी?काहीच करता येत नाही. नेत्रदान/त्वचादान केलं तर देह रक्तबंबाळ विद्रूप होत असेल, देहदान घेण्यासाठी हॉस्पिटल आपल्या घरी वाहन पाठवत असेल, देहदानानंतर अंत्यविधी करता येत नसतील.. अशा अनेक गैरसमजुती?असतात. मात्र या समजुती दूर झाल्या तर अनेक लोकांना दृष्टी मिळेल, त्वचेचं दान मिळेल. फक्त मुंबईतच दरसाल एक लाख व्यक्तींचं निधन होतं. त्या सगळ्यांनी नेत्रदान किंवा त्वचादान केलं तर भारतात एकही?आगीने जखमी?झालेला रुग्ण त्वचेअभावी संसर्गाने निधन पावणार नाही. प्रत्येक कॉर्निअल-अंध बालकाला दृष्टी मिळेल. रस्त्यांवर वाहनांमुळे होणा-या बहुतेक गंभीर अपघातातील रुग्णांचा मेंदू मृत्यू होतो. त्या सर्वाचे अवयव दानात मिळाले तर संपूर्ण आशियायी देशांत अवयव रोपणासाठी अवयवांची?कमतरता भासणार नाही. मृत्यूशय्येवरील रुग्णाला जीवनदान मिळेल. यासाठीच आपटे काकांची राजहंस प्रतिष्ठान ही संस्था गेल्या दशकभरापासून विनामूल्य कार्यरत आहे. अवयवदान म्हणजे काय? अवयवदान जिवंतपणी करता येते. दानात लिव्हरचा काही भाग व एक किडनी फक्त जवळच्या नातेवाइकांना दान करता येते. मस्तिश्क स्तंभ मृत्यू (ब्रेनडेड अवस्थे)नंतर पण अवयवदान करता येते. रुग्ण अतिदक्षता विभागात (आयसीयू) कृत्रिम श्वसनावर (व्हेंटिलेटर) असला तरच अवयवदान करता येते. साधारणपणे ब्रेन हॅमरेज व अपघातात मेंदूला इजा झाली असली तर ब्रेनडेड अवस्था येण्याची शक्यता असते, बहुतेक सर्व चांगल्या स्थितीत असलेले अवयव जवळच्या नातेवाइकांच्या संमतीने दान करता येतात. दानाचा लाभधारक सहकारी यंत्रणा ठरवते. अवयवदानानंतर देह अंत्यसंस्कारासाठी परत मिळतो. नैसर्गिक मृत्यूनंतर ज्या क्षणी माणसाचं हृदय बंद पडतं, त्या क्षणी अन्य सर्व अवयव दानासाठी निरुपयोगी होतात. नैसर्गिक मृत्यूनंतर अवयवदान करता येत नसलं तरी त्वचादान, नेत्रदान व देहदान यापैकी एक वा तिन्ही दाने करता येतात. तिन्ही दान करायची असतील, तर प्रथम त्वचादान, नंतर नेत्रदान व अखेरीस देहदान हा क्रम अवलंबावा लागतो. या उदात्त दानांनी दात्यास अवयव रूपांनी अजरामर केल्याचे स्वर्गीय समाधान नातेवाइकांस मिळते व दानाबद्दल मेडिकल कॉलेजकडून/ त्वचा, नेत्र पेढीकडून सर्टिफिकेट मिळते. मात्र कोणताही आर्थिक लाभ मिळत नाही. या सर्व उदात्त दानासाठी वयाची अट नाही, मात्र जवळच्या नातेवाइकांची संमती असणे आवश्यक असते. कोणतीही सज्ञान स्त्री-पुरुष व्यक्ती नातेवाइकांच्या संमतीने इच्छादानपत्र नोंदणी करू शकते. तशी नोंदणी झाली नसली तरीही जवळच्या नातेवाइकांच्या संमतीने ही सर्व उदात्त दाने करता येतात. ही सर्व दाने स्वीकारण्याचे कार्य सदा सर्वकाळ (२४ ७ ७) सुरू असते. नातेवाइकांनी कळविल्यानंतर 'राजसंह प्रतिष्ठान'चे कार्यकर्ते प्रत्यक्ष उपस्थित राहून सर्वतोपरी सहाय्य करतात. त्वचादान मृत्यूनंतर २-३ तासांत त्वचादान करणे चांगले असते. यासाठी डॉक्टर दात्याच्या घरी येऊन अध्र्या तासाची शस्त्रक्रिया करतात तेव्हा रक्ताचा थेंबही येत नाही. तसेच दात्याचा देह विद्रूपही होत नाही. त्वचादानामुळे आगीने/ अ‍ॅसिडने होरपळून जखमी झालेल्या अनेक रुग्णांचे प्राण वाचवता येतात. प्रक्रिया केलेली त्वचा टिकवून ठेवता येते. नेत्रदान मृत्यूनंतर ३-४ तासांत, त्वचादानानंतर लगेच नेत्रदान करणे चांगले असते. डॉक्टर दात्याच्या घरी येऊन अध्र्या तासाची शस्त्रक्रिया करतात तेव्हा रक्ताचा थेंबही येत नाही. नेत्रदानानंतर कृत्रिम नेत्र बसवतात, त्यामुळे देह विद्रूप दिसत नाही. नेत्रदानातून मिळालेल्या कॉर्नियाच्या उपयोगाने दोन वा अधिक अंधांना दृष्टी मिळू शकते. मोतिबिंदू ऑपरेशन झालेली, चष्मा वापरणारी, रक्तदाब/ मधुमेह पीडित व्यक्तीपण निधनानंतर नेत्रदान करू शकते. दानानंतर कॉर्निया प्रयोगशाळेत तपासून, प्रक्रिया करून त्याचे ४८ तासात प्रत्यारोपण केले जाते. ७० वर्षानंतरच्या दात्याचे नेत्र रोपणासाठी उपयुक्त नसल्यास केवळ संशोधनासाठी वापरला जातो. दानानंतर नेत्रपेढीकडून प्रमाणपत्र मिळते. नेत्राचा लाभधारक निवडण्यास वा नाव समजण्यास कायद्याने प्रतिबंध आहे. देहदान मृत्यूनंतर ५-६ तासांत देहदान करणे चांगले असते. त्यासाठी दात्याचा देह नातेवाइकांनी मेडिकल कॉलेजमध्ये नेऊन द्यायचा असतो. देहदात्याचा अत्यंत जवळचा नातेवाईक परदेशात असेल व १-२ दिवसांत येणार असेल तर त्यास देहदानानंतर दात्याचे दर्शन देण्याची खास व्यवस्था करता येते. कोणतीही सज्ञान स्त्री-पुरुष व्यक्ती देहदान इच्छा नोंदणी करू शकते. ज्यास वयाची अट नसते. देहदान मृत्यूच्या गावापासून जवळ असलेल्या मेडिकल कॉलेजमध्ये स्वीकारले जाते. ज्याचा उपयोग प्रयोगशाळेत डॉक्टरांच्या प्रशिक्षणासाठी व संशोधनासाठी होतो. एका देहावर साधारणपणे दहा डॉक्टरांचे प्रशिक्षण अवलंबून असते. अशा प्रकारे निपुण डॉक्टरने आपल्या ४० वर्षाच्या वैद्यकीय सेवेत दररोज एका रुग्णाचा जीव वाचवला तर एका देहदानापासून प्रशिक्षण घेतलेले दहा डॉक्टर १,२०,००० रुग्णांचे प्राण वाचवतील. यावरून देहदानाचे महत्त्व लक्षात येते. जनजागृती व माहितीच्या अभावामुळे दरवर्षी मुंबईत निधन पावलेल्या १ लाख व्यक्तींपैकी फक्त १०० देहच दानात मिळतात यावरून विषयाचे गांभीर्य लक्षात येते. देहदानानंतर फॉर्मेलीन रसायनाचा वापर करून 'एम्बाल्मिंग' प्रक्रियेने देह काही वर्षे टिकवला जातो. प्रयोगशाळेत अत्यंत आदरपूर्वक प्रार्थना करून प्रशिक्षणार्थी डॉक्टर प्रयोग सुरू करतात. प्रयोगशाळेतील कार्य पूर्ण झाल्यावर सरकारी नियमाप्रमाणे तो देह आदरपूर्वक, गांभीर्याने नष्ट केला जातो. कोणते देह स्वीकारले जात नाहीत? अपघाताने मरण पावलेल्या व बेवारस देहांचे पोस्टमॉर्टम करणे बंधनकारक असते. ज्यात नसांना छेद द्यावा लागतो. 'एम्बालिंग' करून असा देह टिकवणे शक्य नसते म्हणून तसा देह दानात स्वीकारता येत नाही. त्याचप्रमाणे संसर्गजन्य रोगाने मरण पावलेल्या व्यक्तींचा देह स्वीकारता येत नाही, म्हणून टीबी, गँगरीन, डेंग्यू, एड्स, हेपिटायटीस, काविळ, सेप्टिसिमिया इ. रोगांनी निधन झालेल्या व्यक्तींचे देह स्वीकारता येत नाहीत, देहदानानंतर मेडिकल कॉलेजकडून महापालिकेच्या वार्ड ऑफिसरला लिहिलेले पत्र नातेवाइकांना मिळते. ते पत्र महापालिकेच्या मृत्यू नोंदणी कार्यालयात दिल्यावर मृत्यूचा दाखला मिळतो.  त्वचा/ नेत्रदान/ देहदान प्रत्यक्ष करण्याच्या वेळी काय करावे : » दात्याचा देह स्वच्छ ठेवा. » एसी असल्यास तो सुरू करावा व पंखा बंद करावा. » डोळ्यावर थंड पाण्याची घडी ठेवावी व डोक्याखाली २ उशा ठेवाव्यात. » डॉक्टरांना उदात्त दानाच्या निर्णयाची माहिती द्यावी व मृत्यूच्या कारणाचा दाखला लवकर मिळवावा. » सर्व नातेवाइकांना उदात्त दानाची माहिती द्यावी. राजहंस प्रतिष्ठानचे आपटे काका यांना एसएमएस केल्यास घरपोच सर्व माहिती?आणि देहदानाचा फॉर्म पाठवतात. इतकंच नव्हे तर हा फॉर्मपाठवण्यासाठी त्यांचा पत्ता असलेले पाकीटही सोबत पाठवतात. आपटे काका : ९८२००७८२७३.

Proven one-step process to convert CO2 and water directly into liquid hydrocarbon fuel Posted: 22 Feb 2016 07:08 PM PST Chemists and engineers have proven that concentrated light, heat and high pressures can drive the one-step conversion of carbon dioxide and water directly into useable liquid hydrocarbon fuels.

Almond joy: Eating just a handful a day boosts diet health, study shows Posted: 22 Feb 2016 07:08 PM PST Just add a handful of almonds: a University of Florida study suggests that improving one's diet can be as simple as that.

Species groups follow patterns reacting to climate change on US Northeast Shelf Posted: 22 Feb 2016 12:57 PM PST Researchers studying groups of species with similar depth and temperature distribution have found that those groups have similar responses to the effects of climate change. Interactions between individual species in those groups, however, may be affected by the amount of available habitat, predator-prey relationships, and competition for food resulting from shifts in range and distribution. The study evaluated the pace and magnitude of climate change effects for nearly 70 demersal or bottom-dwelling species on the US Northeast Shelf.

New theorem helps reveal tuberculosis' secret Posted: 22 Feb 2016 12:57 PM PST Researchers seek to streamline the analysis of complex biochemical networks and to reveal inconsistencies in biological data. Their theorem helps to uncover hidden drivers of non-monotonic responses to monotonic stimuli in tuberculosis bacteria.

Time of day can impact spray Posted: 22 Feb 2016 12:57 PM PST Some herbicides are more effective when applied at noon compared to early morning or late evening applications, new research indicates. Researchers say the results have long-term implications for weed management.

Researchers advance understanding of turbulence that drains heat from fusion reactors Posted: 22 Feb 2016 12:56 PM PST Physicists at the US Department of Energy's Princeton Plasma Physics Laboratory appear to have gained important new insights into what affects plasma turbulence, which can impact the leakage of heat from the fusion plasma within tokamaks. Understanding how fusion plasmas lose heat is crucial because the more a plasma is able to retain its heat the more efficient a fusion reactor can be.

Bat 'super immunity' could help protect people Posted: 22 Feb 2016 12:56 PM PST For the first time, researchers have uncovered a unique ability in bats which allows them to carry but remain unaffected by lethal diseases.

Some distractions while driving are more risky than others, researchers say Posted: 22 Feb 2016 12:56 PM PST Drivers more than double their crash risk for more than half of their trips when they choose to engage in distracting activities.

Antarctic ice sheet is more vulnerable to carbon dioxide than expected Posted: 22 Feb 2016 12:56 PM PST Results from a new climate reconstruction of how Antarctica's ice sheets responded during the last period when atmospheric carbon dioxide reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric carbon dioxide than previously thought.

Tracking prejudices in the brain Posted: 22 Feb 2016 12:18 PM PST We do not always say what we think: we like to hide certain prejudices, sometimes even from ourselves. But unconscious prejudices become visible with tests, because we need a longer time if we must associate unpleasant things with positive terms. Researchers now show that additional processes in the brain are not responsible for this, but some of them simply take longer.

Researchers use Botox-like injection to treat runners, cyclists with knee pain Posted: 22 Feb 2016 12:18 PM PST A painful knee condition that affects more than one in eight active people has been treated effectively with a botulinum toxin injection and physiotherapy.

Which discipline or reward is best for your child? Posted: 22 Feb 2016 12:18 PM PST A new study lends insight into how children react to discipline practices used by parents and teachers, and sheds light on their view of what's fair.

Earth science: Remote predictions of fluid flow in fractures possible with new finding Posted: 22 Feb 2016 12:16 PM PST A team of researchers has created a way to quickly and remotely evaluate fluid flow in subsurface fractures that could impact aquifers, oil and gas extraction, sequestration of greenhouse gases or nuclear waste and remediation of leaked contaminants.

Toddler screening essential for autism detection despite national task force's reservation Posted: 22 Feb 2016 12:16 PM PST Given that earlier diagnoses have been found to be more beneficial for treating children on the autism spectrum, a team of researchers believes that universal screening in 18-24 month-old children remains essential, despite a federal task force deciding there is insufficient evidence to recommend it.

Fungi are at the root of tropical forest diversity, or lack thereof, study finds Posted: 22 Feb 2016 12:16 PM PST The types of beneficial fungi that associate with tree roots can alter the fate of a patch of tropical forest, boosting plant diversity or, conversely, giving one tree species a distinct advantage over many others, researchers report.

Fish of dinosaur era with unique 'hook-shaped sail' on its back Posted: 22 Feb 2016 12:16 PM PST A 90-million-year-old fossil fish, currently on display at the Perot Museum of Nature and Science in Dallas, turns out to be a new species. Research reveals the 5.5-foot-long fossil fish to possess a tuna-like body with a unique 'hook-shaped sail' on its back. The fish's new species name, Pentanogmius fritschi, is in honor of local amateur collector Joseph Fritsch.

Intense deep-ocean turbulence in equatorial Pacific could help drive global circulation Posted: 22 Feb 2016 12:16 PM PST The findings could help solve an outstanding mystery about the global ocean conveyor belt and improve future climate forecasts.

Non-destructive technique measures oxygen levels in 3-D cells used for toxicity testing Posted: 22 Feb 2016 12:16 PM PST A non-destructive technique that can measure the concentration and consumption of oxygen in 3-D models of biological cells has been developed by scientists.

Charging electric vehicles at night can cause more harm than good, says study Posted: 22 Feb 2016 11:45 AM PST While charging electric vehicles at night is more cost-effective, it increases air emissions, new research demonstrates.

Graphic images may not scare smokers off cigarettes, says study Posted: 22 Feb 2016 11:45 AM PST Images of disease and suffering should move smokers to kick the habit – at least, that's the thinking behind graphic warning labels used on cigarette packages in much of the world, and maybe someday in the U.S.

The little things: Gratitude and shared laughter strengthen romantic partnerships Posted: 22 Feb 2016 11:45 AM PST Research suggests gratitude and shared laughter strengthen romantic partnerships.

Phase 2 clinical trial to treat rare hereditary muscle disease shows promise Posted: 22 Feb 2016 11:43 AM PST Researchers present the first clinical study that provides evidence that an extended-release sialic acid supplement may stabilize muscle strength in patients with GNE myopathy (GNEM), a rare hereditary, progressive, adult-onset muscle disease.

Dried plums provide protection from bone loss due to radiation, study shows Posted: 22 Feb 2016 11:43 AM PST Dried plums are effective in protecting from bone loss due to iodized radiation, a new study shows. The study showed consuming dried plums can protect from ionizing radiation that increases oxidative damage in skeletal tissues and results in an imbalance in bone remodeling.

New surgical technique improves biological hip joint replacement Posted: 22 Feb 2016 11:43 AM PST Traditional hip replacement procedures reduce pain and restore mobility.
