Pengen dapet jurnal, tetapi berbayar ??? :'(


Umz ini pengalamanku, kemarin aku searching jurnal terkait penelitianku, eh ternyata penelitian terbaru 2014 semua berbayar, ku coba saja untuk menghubungi author-nya siapa tahu bisa membantu, Alhamdulillah dapat respon baik, dikasih ntu urnal jurnal tentang penelitian beliau dan dikasih id pula……So ada kemauan pasti ada jalan dan alam akan mensingkronkan dirinya untuk mendukung kemauan itu, kalau kata Prof. Yohanes Surya dulu “Mestakung” Semesta Mendukung 🙂

Melalui Goresan


Ku sampaikan pada yang tersimpan

Ku tuangkan impian melalui goresan tangan

Dalam impian tersimpan keinginan

Dalam keinginan ada harapan

Berharap ada kepastian

Menyepi dalam ramainya kerinduan

Bahagia senantiasa bersamanya

dan semua hanya atas ijin Nya

Sang Pemilik rasa

Pencipta dan pemberi segalanya

Could the Intestinal Microbiota Influence Brain Development


Could the microbes that inhabit our guts help explain that old idea of “gut feelings?” There’s growing evidence that gut bacteria really might influence our minds.gutbrain-connectionfinal

“I’m always by profession a skeptic,” says Dr. Emeran Mayer, a professor of medicine and psychiatry at the University of California, Los Angeles. “But I do believe that our gut microbes affect what goes on in our brains.”

Mayer thinks the bacteria in our digestive systems may help mold brain structure as we’re growing up, and possibly influence our moods, behavior and feelings when we’re adults. “It opens up a completely new way of looking at brain function and health and disease,” he says.

So Mayer is working on just that, doing MRI scans to look at the brains of thousands of volunteers and then comparing brain structure to the types of bacteria in their guts. He thinks he already has the first clues of a connection, from an analysis of about 60 volunteers.

Mayer found that the connections between brain regions differed depending on which species of bacteria dominated a person’s gut. That suggests that the specific mix of microbes in our guts might help determine what kinds of brains we have — how our brain circuits develop and how they’re wired.

Of course, this doesn’t mean that the microbes are causing changes in brain structure, or in behavior.

But other researchers have been trying to figure out a possible connection by looking at gut microbes in mice. There they’ve found changes in both brain chemistry and behavior. One experiment involved replacing the gut bacteria of anxious mice with bacteria from fearless mice.

“The mice became less anxious, more gregarious,” says Stephen Collins of McMaster University in Hamilton, Ontario, who led a team that conducted the research.

It worked the other way around, too — bold mice became timid when they got the microbes of anxious ones. And aggressive mice calmed down when the scientists altered their microbes by changing their diet, feeding them probiotics or dosing them with antibiotics.

To find out what might be causing the behavior changes, Collins and his colleagues then measured brain chemistry in mice. They found changes in a part of the brain involved in emotion and mood, including increases in a chemical called brain-derived neurotrophic factor, which plays a role in learning and memory.

Scientists also have been working on a really obvious question — how the gut microbes could talk to the brain.

A big nerve known as the vagus nerve, which runs all the way from the brain to the abdomen, was a prime suspect. And when researchers in Ireland cut the vagus nerve in mice, they no longer saw the brain respond to changes in the gut.

“The vagus nerve is the highway of communication between what’s going on in the gut and what’s going on in the brain,” says John Cryan of the University College Cork in Ireland, who has collaborated with Collins.

Gut microbes may also communicate with the brain in other ways, scientists say, by modulating the immune system or by producing their own versions of neurotransmitters.

“I’m actually seeing new neurochemicals that have not been described before being produced by certain bacteria,” says Mark Lyte of the Texas Tech University Health Sciences Center in Abilene, who studies how microbes affect the endocrine system. “These bacteria are, in effect, mind-altering microorganisms.”

This research raises the possibility that scientists could someday create drugs that mimic the signals being sent from the gut to the brain, or just give people the good bacteria — probiotics — to prevent or treat problems involving the brain.

One group of scientists has tested mice that have behaviors similar to some of the symptoms of autism in humans. The idea is that the probiotics might correct problems the animals have with their gastrointestinal systems — problems that many autistic children also have.

In the mice, many of their autism behaviors were no longer present or strongly ameliorated with probiotics, says Paul Patterson at the California Institute of Technology in Pasadena, Calif. His research will be published soon in the journal Cell.

Experiments to test whether changing gut microbes in humans could affect the brain are only just beginning.

One team of researchers in Baltimore is testing a probiotic to see if it can help prevent relapses of mania among patients suffering from bipolar disorder.

“The idea is that these probiotic treatments may alter what we call the microbiome and then may contribute to an improvement of psychiatric symptoms,” says Faith Dickerson, director of psychology at the Sheppard Pratt Health System.

“It makes perfect sense to me,” says Leah, a study participant who has been diagnosed with bipolar disorder. She agreed to talk with NPR if we agreed not to use her full name. “Your brain is just another organ. It’s definitely affected by what goes on in the rest of your body.”

It’s far too soon to know whether the probiotic has any effect, but Leah suspects it might. “I’m doing really well,” she says. “I’m about to graduate college, and I’m doing everything right.”

Mayer also has been studying the effects of probiotics on the brain in humans. Along with his colleague Kirsten Tillisch, Mayer gave healthy women yogurt containing a probiotic and then scanned their brains. He found subtle signs that the brain circuits involved in anxiety were less reactive, according to a paper published in the journal Gastroenterology.

But Mayer and others stress that a lot more work will be needed to know whether that probiotic — or any others — really could help people feel less anxious or help solve other problems involving the brain. He says, “We’re really in the early stages.”

Sihir


Aku tak tahu ini apa

Ada sinar dari sorot matanya

Ada damai terpancar dari senyumanya

Ada ketenangan terekspresi dari ucapanya

Ada keanggunan dari setiap langkah kakinya

Aku tak tahu ini apa

Darahku mengalir deras saat disisinya

Jantungku berdetak kencang saat mendengar tentang dia

Tak sanggupku berkata-kata

Hanya diam yang mampu kulakukan

Aku tak tahu ini apa

Kehadiranya mampu memnyihirku

Tingkah-lakunya berbeda

Dia unik, dia lucu dan dia …….

Kharakteristiknya mengundang rindu

Ingin selalu ada di dekatnya

Ingin selalu bersamanya

Ingin selalu mendengarkan ceritanya

Inginku tahu lebih tentang dirinya

“Papa”


Usah kau lemparkan batu lantas kau membisu

Usah kau bermain mata lantas kau melanjutkanya

Usah kau bermain telinga lantas kau tahu suaranya

Usah kau bermain kata lantas kau buka mulut semaunya

Merangkak jalan dan berlari

Beribu duri menjadi leri

Berbilah batu menjadi abu

Redam remuk buang dan tinggalkan dalam

detik menit jam

Cukil sejumput rubi

kau jadikan bekal nanti

Alam diam dalam salam

malam membisu penuh kata

Siang bernyanyi tanpa melodi

Nadi mengalir tiada bertepi

Jantung memompa kekosongan

Otak liar dan tandus dalam pikir

Akal bergerak statis

Hati penuh lubang berduri

Berkata tiada tata

Rintih tak berperih

Itulah “Papa
