Cea mai tare chestie pe care am citit-o in ultimele zile (despre refugiatii din Siria)

A fost AMA-ul (ask me anything) de pe Reddit cu un refugiat sirian de 18 ani, care e de 9 luni in Germania (in Lebach, undeva langa granita cu Franta/Luxemburg).

Foarte tari raspunsurile lui (spicuiesc):

[–]StraightOuttaSyria[S] 598 points 12 days ago

Well, I had to enter Turkey illegally, so my first encounter in Turkey was with a boot of a soldier, I got beaten up, jailed for three days, then returned back to Syria, one week later I payed ( via a smuggler) some soldiers to let me in Turkey, they took me to the nearest police station where I got a piece of paper with my name on it as an ID card, the town was a majority Kurds, who support PKK, I couldn’t leave the town because that “ID Card” was just for that town, couldn’t work or rent, and they didn’t accept me in the camps on the borders because I’m a single guy ( priority for families and single mothers ), so here’s me, no place to sleep, not allowed to work, can’t go to a school, in the streets, so I decided that Europe was my last solution.

2- “You come to our countries and take our hard earned money, leeching off the welfare system…”

I don’t know how the welfare system works in you country, so I can only speak about the German one, here every refugee gets assistance after being granted asylum, they have to take mandatory integrating and languages courses, which qualify them later to find a job and live on their own, these courses take about 9 months, after passing them, they start pressing you to look for a job, if you couldn’t find one, they look for one for you, and you have to work, you can’t live off the system all your life, I imagine it’s the same through the EU, read about your welfare system in country please.

3- “You are coming in mass numbers, you’re backwards and will commit many crimes…”

Yup, many people came in mass numbers, but we won’t commit crimes, why do you think all these people are criminals? if in Syria, where the judicial and executive branches are well corrupted, and poverty is wide spread, crime wasn’t common at all, at least in my region, so why exactly would these people have a change of heart in a more welcoming and safe country?

4- “Are there ISIS jihadists among the refugees?”

Yes, that is quite a high possibility.

7- “Why does people leave Hungary, Greece, Bulgaria even though it’s quite safe there?”

Because they want a better life, I know it’s such a bad excuse but that’s reality, and I think western Europe take them, not to fulfill their dreams, but to ease the burden on these countries, which can’t possibly manage such huge floods of people, specially in their current economic environment. Does everyone deserve to go to western Europe? nope, personally If I got to Hungary I would definitely stay there, because leaving the country for Germany would be a huge insult to the people of Hungary ( it’s like telling them I’m better than the whole 10 millions of you! ), so take the families from these countries, ease the burden on your neighbors.

Cum a strans banii?

How did you finance your trip? How much did the smuggler(s) ask for?
[–]StraightOuttaSyria[S] 825 points 12 days ago
sorry didn’t notice your reply.
I had an internet cafe in Syria which brought in very well, and my Dad completed the necessary amount, which was around 11000 euros.
[–]Legendoflemmiwinks 277 points 12 days ago
Did your internet cafe require goverment compliance. Did you have to allow them to install a monitoring system? Were you aware of such things going on that relates to this?
[–]StraightOuttaSyria[S] 425 points 12 days ago
I opened it after the war started, there’s no internet connection, or any telecommunication for that matter, there’s no goverment where I was, no I didn’t monitor anyone.
[–]fuck_with_me 586 points 12 days ago
internet cafe
no internet connection
..what?
[–]StraightOuttaSyria[S] 841 points 12 days ago
hahhha, there was no internet connection through ADSL or 3G, so I bought a satellite subscription and opened my cafe, sorry for the confusion.

Si partile amuzante:

[–]TheMindsEIyIe 80 points 12 days ago
Pretty fucking genius for a 16-17 year old (since you are 18 now). What was stopping other Syrians from getting satellite internet?
[–]ValikorWarlock 227 points 12 days ago
not having internet to order it

[–]Consilio_et_Animis 353 points 12 days ago
Ha! That is the most wonderful question. Thank you.
It get’s right to the heart of why mixing folks from different countries is so good. I live in EU, and if I step out of my door now, I am 50m from these restaurants/take-aways.
Turkish / Greek / Indian / Bangladesh / Italian Pizza / Asian Fusion (whatever that is) / Israeli deli & coffee shop
And many of these establishments have authentic people from the relevant countries running them.
[–]StephenSwat 197 points 12 days ago
I live in Amsterdam and there’s an actual North Korean restaurant near my house. It serves proper North Korean food and is staffed by actual North Koreans.
It is also probably a money laundry run by the North Korean government, but whatever.
[–]el___diablo 492 points 12 days ago
It serves proper North Korean food
Can’t help but imagine you being served an empty plate.

Chiar e un lant de restaurante prin care Coreea de Nord spala bani. Ha!

[–]StraightOuttaSyria[S] 501 points 12 days ago
That’ll be a bit hard, so in short:
Got a fake Italian ID card, practiced English with an Italian accent, some high-end clothes and hairstyle, got a plane ticket to Germany, and got here 🙂
[–]alrayyes 72 points 12 days ago
Am I the only one immediately reminded by that one scene in Inglorious Basterds?
[–]VickyRhinoHooffs 34 points 11 days ago
Arrivheerrdheerrshe

Adica scena asta:

Si continuarea, pentru ca m-am gandit ca undeva, cumva, un italian va citi asta si va zice “aha, din cauza astora ma tot freaca politistii vamali in aeroporturi!”:

[–]andythemo 19 points 11 days ago
so THAT’S WHY I always have to spend so much time at passport control whenever I come back to Europe (I’m an Italian living in the middle east)

Ce mai creeaza cercetatorii in laborator? Rinichi, uretere si o vezica urinara – conectate si functionale

P5560008-Kidneys_and_ureters%2C_X-ray-SPL

Nu, nu e vorba de cercetatorii britanici, ci de unii japonezi, care si-au publicat rezultatele in PNAS.

Pentru a fi corecti, au reusit sa creeze niste rinichi embrionari (metanephros*-metanefroi la plural), niste uretere pe care le-au conectat la acestia si o vezica urinara, in care urina secretata de rinichi s-a putut varsa.

In prima faza au creat din celule stem rinichi embrionari functionali (secretau urina) transplantabili si functionali in porci – dar nu aveau nici un mod de-a elimina urina secretata, deci se umflau cu urina (hidronefroza).

Ulterior au folosit un fel de esafodaj pentru a obtine uretere si o vezica urinara incipienta (din cloaca embrionara), le-au conectat pe toate si le-au transplantat intr-un sobolan. Au observat ca sistemul functiona (urina era secretata si stocata in vezica). Au obtinut aceleasi rezultate si la porci – sistemul transplantat a functionat pentru cel putin o vreme.

Desigur, sunt doar rezultate preliminarii, mai trebuiesc facute teste si multe observatii ulterioare (evolutia in timp a organelor, toleranta lor de catre organismul-gazda, eventualele complicatii samd). Deci rinichiul artificial crescut de la 0 este inca la multi ani distanta (daca va exista vreodata).

Stire de aici.

Metanephros e un stadiu al evolutiei rinichilor la embrionul mamiferelor (in jurul a 5 saptamani la oameni) in care rinichii sunt aproape in totalitate formati, avand deja mii de nefroni grupati impreuna (adultul are in jur de 1 milion de nefroni/rinichi) in structurile prin care se strange urina (canale colectoare, calice si pelvisul renal).

I-am “facut” pe americani intr-un top medical

Atata doar ca e vorba de un top in care nu am vrea sa fim.

Conform datelor (la nivelul lui 2013) colectate in spitalele universitare Romania din culturile de sange sau lichid cefalorahidian si raportate in European Antimicrobial Resistance Surveillance Network (EARS-Net) – parte din ECDC, in Romania avem o problema destul de grava cu stafilococul auriu rezistent la meticilina (MRSA). Procentual, stam mai rau ca SUA, India, Vietnam, Belarus sau Grecia si Portugalia (alte tari cu un numar mare raportat de cazuri detectate de s. auriu rezistent la antibiotice. Tot raportul aici. In perspectiva (mai intunecat = mai rau):

Screen Shot 2015-09-18 at 21.49.13

Reprezentare grafica de aici. Pacat ca nu au si o harta interactiva pentru MDR-TB sau XDR-TB, atunci ar fi si mai trist locul nostru (in 2012 aveam 1300 de noi pacienti cu TBC rezistent la medicamente).

Am ajuns la reprezentarea asta grafica citind un articol foarte interesant despre “De ce este India un focar pentru rezistenta la antibiotice si Suedia nu“.

In esenta, se reduce totul la prescrierea antibioticelor intr-un mod rational (adica nu pentru orice raceala) si la educarea populatiei sa le foloseasca cu masura.

E adevarat, nu mentioneaza daca industria alimentara din Suedia foloseste mai putine antibiotice (procentual sau relativ la dimensiune) decat cea din India.

Vii cu un ceas asamblat de tine la scoala si esti arestat ca posibil terorist

Numai in ‘Murrica.

Stire de aici, aici sau aici.

Elevul de 14 ani de mai jos are o placere aparte in a asambla si dezasambla electronice acasa. A adus un ceas electronic asamblat de el la scoala, i l-a aratat profesorului sau, care a chemat prompt politia sub suspiciunea unui atentat cu bomba. Pentru ca, nu-i asa, un terorist vine la scoala si ii arata unui tampit o bomba. “Terorist” care arata asa (NASA!):

Asta se intampla intr-un orasel din Texas in care ai voie sa mergi cu arme la scoala (ca elev – atata timp cat nu o aduci in interiorul cladirii de cursuri fara permisiune). Deci daca aduci un pistol, e ok. Daca aduci un ceas, esti detinut 5 ore si amenintat cu tot felul de porcarii.

Apoi scoala mai are si nerusinarea sa trimita o scrisoare catre toti elevii in care se aplauda singura pentru actiunea “excelenta” luata pentru a “proteja” elevii sai albi de un elev (intamplator) musulman care indrazneste sa asambleze un ceas electronic. Evident, scrisoare cu un dezacord gramatical, ca sa stim cine are fraiele in situatii din astea.

Recunosc, “ceasul” cu pricina poate arata relativ bizar, dar bomba? Cat de tampit sa fii sa crezi asta – mai ales ca profesor?

Cu o populatie din ce in ce mai abrutizata si speriata si tampita cu mass-media… la ce te poti astepta?

Cel mai trist e faptul ca tot felul de tampiti vor considera ca elevul cu pricina merita acest comportament execrabil, doar pentru ca avea alta religie, exista protocoale pentru a raspunde la orice fel de amenintare si… “freedom has to be preserved”.

Cui ii mai pasa de libertatea copilului asta?

Microbiologie si arta

In microbiologia clinica se foloseste cultivarea in discuri Petri cu agar-agar pentru a izola si identifica bacteriile (si fungii) sau pentru a testa/monitoriza terapia antimicrobiana.

Agarul este un amestec organic (polizaharide 70-80%, apa si substante minerale), extras cu ajutorul apei fierbinti din niste alge rosii marine (agarofite), care se prezinta sub forma gelificata. Agarul asigura suprafata de cultura pentru bacterii – dar nu e chiar “hrana”, pentru ca majoritatea bacteriilor nu pot sa-l foloseasca pentru metabolismul lor. Pentru asta se adauga alte ingrediente, nutrienti, factori de crestere si indicatori de pH in mediul cu agaroza. Exista medii lichide, solide (selective, neselective, diferentiale) sau semisolide.

Ok, suficienta teorie. Site-ul educational microbeworld.org al American Society for Microbiology a organizat un mini-concurs zilele acestea, cautand imagini interesante cu culturi bacteriene sau fungice in discuri petri. Ce a iesit puteti vedea aici. O mica selectie am facut si eu:

Ce se intampla cand o asistenta medicala incurca 2 perechi de gemeni intre ei?

Exact ce ai crede: 2 familii cresc cate 1 copil care nu e al lor pentru cateva zeci de ani.

La sfarsitul lui 1988, 2 perechi de gemeni se nasteau prematur in 2 orase diferite din Columbia. Unii in regiunea mai saraca Santander, altii intr-o clinica din Bogota. Cei din provincie sunt transferati in clinica mai bine dotata din capitala, unde incurcatura se petrece. De aici, cei 4 baieti cresc incurcati pentru 25 de ani, convinsi ca sunt gemeni fraterni (dizigoti), nu gemeni din acelasi ovul (monozigoti).

2 perechi de gemeniSi, pentru ca viata bate filmul, cei 4 reusesc sa se intalneasca printr-o serie de intamplari fericite si… minunea retelelor sociale.

N-o sa stric tot articolul pentru cine e curios, doar vroiam sa adaug ca, in afara de povestea de Hollywood, cazul asta are si implicatii foarte interesante pentru genetica, in special pentru cercetarea in domeniul epigeneticii. Adica influenta pe care o au factorii de mediu asupra celulei si felul in care activeaza si inactiveaza acestia anumite gene.

Cercetarile pe gemeni sunt foarte utile in genetica – pentru ca se pot cuantifica diferentele din viata acestora si efectul lor asupra sanatatii lor (si psihicului si nu numai). Gemenii de genul acesta (separati 25 de ani) sunt foarte greu de gasit si pot fi folositi ca brat blind al unei cercetari – nestiind ca sunt gemeni, nu pot influenta cu nimic voit anumite date ale cercetarii.
