*Pray for Paris*
Tragedi paris membuat kita sedih sekaligus geram. berbagai kejadian yang issue-nya ditimpakan kepada umat islam bukan saja terjadi di luar negeri, namun juga banyak kita temui di dalam negeri.
Dibutuhkan kekuatan ukhuwah di dalam diri umat islam agar pihak di luar islam tidak lagi mudah menuduh umat islam sebagai dalang di berbagai kejadian buruk yang terjadi. salah satu contohnya saat ini adalah peristiwa terorisme di paris yang saat ini menjadi pembicaraan hangat di dunia.
PRAY FOR PARIS. mereka saudara kita....!!!
============================
In the 24 hours following the terror attacks that claimed the lives of 129 people in Paris, more than 70 million people took to Instagram to share their support and prayers for the French capital, according to the social network.
In total 430 million interactions–that’s posts, likes and comments–were created in these first 24 hours, with people in more than 200 countries participating. Jean Julien’s “Peace for Paris” logo became a symbol in this wave of support, especially after Instagram shared the drawing on its official account, which has 114 million followers.
Users also embraced hashtags, which were trending for most of the weekend. They were:
#prayforparis
#paris
#jesuisparis
#france
#prayersforparis
#peace
#pray
#prayfortheworld
#love
#peaceforparis
Emojis expressing grief (from sad faces to broken hearts) were also among the most used hashtags, topped by the French flag and prayer hands emojis.
The high number of interactions comes a few weeks after Instagram announced it had 400 million unique users and that it was putting more resources on curating content. “We believe you can see the world happening in real time through Instagram,” Instagram’s co-founder Kevin Systrom told TIME.

Perceived Parental Criticism, Self-Criticism and Depression: An Exploratory R...Gabriele Caselli
This study explored the relationships between perceived parental criticism, self-criticism, rumination, concern over mistakes, and depression. The researchers found that perceived parental criticism indirectly predicted self-criticism through its effects on rumination and concern over mistakes. Self-criticism directly predicted depression, over and above the effects of rumination and concern over mistakes. The results suggest early experiences with parental criticism can influence negative cognitive styles like self-criticism, which then maintain depressive symptoms. Addressing self-criticism may be important for preventing and treating depression.

Commercial considerations in early drug developmentSunil Ramkali
It is important in the drug development process that marketers and researchers collaborate early to ensure that products being developed are truly innovative and deliver brand value to the different end users in a way that the product and the subsequent brand messaging is relevant, compelling and differentiating compared to the competition. T
In the market place that is heavily cost constraint, innovation is no longer about a unique mode of action or a new formulation, but more about the incremental brand value offered by new pharmaceutical products over existing treatments (standard of care) and how much healthcare systems are prepared to pay for these incremental benefits. My lecture at the Department of Innovation, Lund University, Sweden explored the importance of R&D functions getter closer to external stakeholders to really understand their needs, how they define brand value and the importance of considering this early in the drug development process.

The document discusses neural correlates of higher level brain functions. It covers several topics:
1) Experience arises at the quantum level in ion channel proteins, with quantum properties like coherence and entanglement playing a role.
2) Construction of perception involves transitions from quantum to classical domains in the brain, mediated by ion channel proteins. Top-down processes and long-range connections in large brains are important for conscious perception.
3) Perception emerges from complex interactions between ascending and recurrent signaling in the brain, with feedback thought to be crucial for awareness. Receptive field properties evolve along synaptic distances in hierarchical cortical networks.

The document discusses brain nutrition and glucose homeostasis. It notes that the brain relies primarily on glucose as an energy source and that impaired glucose regulation can contribute to cognitive decline and Alzheimer's disease. Maintaining normal blood glucose levels is important for brain health. The document also discusses how omega-3 fatty acids like DHA found in fish are important for brain structure and function and may help protect against cognitive decline. Following a Mediterranean diet with fish, olive oil, fruits and vegetables may help support brain health.
This document discusses the possibility of using computational drug design for neurological disorders. It summarizes research showing that microtubules in neurons may function as quantum computers capable of vast information processing and storage comparable to the human brain. Various neurological diseases like Alzheimer's, Parkinson's, and ALS involve disruption of microtubule structure and function. The document proposes that stabilizing microtubules through drug design could help treat and prevent neurodegeneration in these diseases. It reviews evidence that general anesthetics may interact with and alter microtubules, influencing memory formation and consciousness. Overall, the document argues microtubules are promising targets for computational drug design approaches to neurological disorders.

This document summarizes research on fatty acid alterations in mood disorders and metabolic syndrome. Key points:
1) Studies have found low omega-3 PUFA levels and increased omega-6/omega-3 ratios in depressed patients compared to controls. Lipid peroxidation products and homocysteine are also elevated while folate is decreased.
2) Alterations in fatty acid composition in erythrocytes and plasma of depressed patients involve saturated, monounsaturated, and polyunsaturated fatty acids of different chain lengths. Desaturase and elongase enzyme activity is affected.
3) These fatty acid changes are partly due to diet but also reflect increased oxidative stress from genetic, lifestyle, metabolic
This document discusses David Bohm's interpretation of quantum theory and its implications for the mind-body problem. It summarizes Bohm's view that particles have both particle and wave properties, with the wave guiding the particle. Bohm proposed that information carried by a quantum field actively guides particles. Similarly, mental information may be carried by subtle fields or potentials that actively organize brain processes. This provides a framework for understanding how mind and matter can mutually influence each other.
1. Microtubules may be involved in psychopathology through their roles in cellular processes and potential for information processing.
2. Dysfunction of microtubule polymerization and depolymerization cycles could underlie mental illnesses like depression through abnormal protein transport and neural activity.
3. Impaired quantum information processing in microtubules has been proposed as a potential mechanism contributing to mental illnesses. More research is needed to validate these microtubule-based models of psychopathology.
This document discusses paradigm shifts in psychiatry, specifically moving away from the dominant biomedical model. It outlines Thomas Kuhn's theory of paradigm shifts in science and provides examples. The document argues for a new paradigm in psychiatry based on quantum physics, which avoids mind-body dualism and allows for concepts like psychogenic causality, backward causality, and free will. It suggests quantum physics provides insights used intuitively by psychiatrists.
1) Quantum theories may help explain emergent self-organization phenomena in life, brain, cognition, and consciousness that traditional mechanistic frameworks cannot.
2) Decoherence due to environmental interactions is a challenge for quantum theories of mind, but decoherence depends on specific contexts and some coherence mechanisms may cooperate.
3) Higher-order statistical analyses of mesoscopic and macroscopic observations may reveal signatures of underlying quantum phenomena in the brain even if simple average quantities do not.
1. Proteina Gs alpha come
biomarker per la depressione
Sabina Bucciarelli
30/03/2012
2. Nonostante decenni di ricerca, le basi biologiche della
depressione non sono note, e gli obiettivi molecolari
e cellulari del trattamento antidepressivo rimangono
sfuggenti.
Alcuni ricercatori dell’UIC (University of Illinois
at Chicago) College of Medicine ed in particolare del
dipartimento di Physiology and Biophysics hanno
scoperto che un cambiamento nella posizione di una
proteina nel cervello potrebbe fungere
da biomarker per la depressione.
La proteina oggetto di studio è una proteina di
membrana la Gs alpha implicata nella trasmissione
degli impulsi nervosi, ed importante modulatore del
segnale per la serotonina.
3. Gs Alpha
Le proteine G sono un sottogruppo di
una superfamiglia di GTP asi.
Possiamo distinguere due ampie
classi di GTPasi: le GTPasi
monomeriche e le proteine G
eterotrimeriche, costituite cioè da tre
subunità proteiche. Le subunità α, β e
γ vengono divise generalmente in
subunità α e complesso βγ, agendo
quest'ultimo come un'unità. Queste
proteine sono direttamente associate a
recettori di membrana, conosciuti
come recettori serpentina o recettori
collegati a proteine G.
4. Nello stato inattivo la subunità α lega
GDP ed è strettamente legata al
complesso βγ. Il legame di una
molecola segnale con il recettore ne
provoca un'alterazione
conformazionale, che si riflette
direttamente sulla subunità α che a
sua volta cambia conformazione. Il
cambiamento conformazionale
determina una dissociazione della
subunità α dal complesso βγ, per
sostituire poi il GDP legato con un
GTP assumendo così lo stato attivo.
5. Il Prof. Mark Rasenick, professore emerito dell’UIC di fisiologia e
biofisica insieme alla sua equipe ha scoperto che la Gs alpha è
disposta in modo anomalo sulla membrana delle cellule dei pazienti
depressi e quindi funziona di meno, impedendo il corretto passaggio
del segnale.
La Gs alpha si muove liberamente nelle membrane di pazienti normali,
permettendo la trasmissione del segnale, cosa che non si verifica
nelle persone con problemi di depressione.
6. La proteina Gs Alpha, sulla superficie delle cellule dei pazienti depressi
è intrappolata in una 'palude' detta raft lipido (fig) di molecole di
grasso e non può interagire con la serotonina. La viscosità della
membrana può modificare lo stato delle Gs,un aumento
(colesterolo, lipidi) diminuisce la mobilità o fluidità, e quindi la Gs
rimane intrappolata.
7. La stabilità dell’umore è influenzata dalla perdita
della fluidità della membrana, si perde la
comunicazione tra le cellule, quindi si verificano
fenomeni depressivi.
E’ stato inoltre dimostrato (M.Rasenick) che la Gs
riprende la sua normale funzionalità dopo
trattamenti antidepressivi che ripristinano la
fluidità della membrana.
8. Nel recente studio patrocinato dalla Regione Marche, condotto negli
Stati Uniti, presso il laboratorio del prof. Mark Rasenick, sono stati
analizzati campioni di sangue, in particolare si è quantificata la Gs
nelle membrane piastriniche.
E’ noto che esistono delle strette correlazioni enzimatiche, metaboliche
e similitudini fra le piastrine e le cellule nervose.
Molto verosimilmente perché le piastrine possiedono caratteristiche
molto simili s’ipotizzano come derivate dallo stesso foglio
embrionale del neurone.
Per tali motivi le piastrine da qualche tempo considerate dei markers
biologici in psichiatria, vengono anche chiamate “neuroni circolanti”
o “ambasciatrici del cervello” e potrebbero offrire un rilevante
vantaggio nella comprensione della neurofisiologia di vari disordini
psichiatrici.
9. Nel nostro studio sono state coinvolte diverse
tipologie di pazienti per un totale di 92 campioni:
11. Tecnica del western blot
• Per analizzare i livelli di proteina
Gs alpha abbiamo utilizzato la
tecnica del western blot. Una
tecnica in cui le proteine sono
separate mediante elettroforesi su
gel e successivamente trasferite
su un supporto (membrana o
filtro). Successivamente una
specifica proteina viene
identificata mediante la sua
reazione specifica con un
anticorpo.
12. Fasi di un western blot
Prima fase: elettroforesi su gel.
Le proteine sono separate in base alla dimensione
13.
14. Terza fase: saturazione o “blocking”.
Per saturare i siti idrofobici liberi sulla membrana (BSA)
Quarta fase: legame dell’anticorpo primario.
17. A cosa serve il western blot?

18. Conclusioni
Si potrebbe ,quindi, con una semplice analisi
del sangue, provare a diagnosticare una
sindrome depressiva. Utilizzare questo
come ulteriore strumento per avvalorare le
diagnosi mediche psichiatriche.
