Accidente ştiinţifice care au dus la mari descoperiri!
Ne este greu să ne imaginăm cum au fost inventate anumite produse, mai ales dacă vorbim despre inovaţii ce au schimbat lumea. Totuşi, unele dintre cele mai cunoscute invenţii au fost create din greşeală în timp ce oamenii de ştiinţă încercau să descopere alte lucruri.Pe lângă penicilină, “Amprenta ADN” în criminalistică, coloranţii sintetici, cipsurile, fursecurile cu ciocolată şi fulgii de porumb, mai există o multitudine de lucruri , (unele pe care chiar le utilizăm frecvent) ce au fost create din greşeală, atunci când oamenii de ştiinţă urmau cu totul şi cu totul altceva.
2. În jurul anului 1675, omul de ştiinţă Hennig Brand, din Germania, păstrează 50 de găleţi de urină în pivniţă, în speranţa că va găsi o metodă prin care să facă aur. De fapt, ceea ce căuta el era „piatra filosofală” despre care se spune că ar avea puterea de a transforma metalele obişnuite în unele preţioase.

June 17, 2011 — Results of a new study provide more evidence that diet may modulate the risk for Alzheimer's disease.
In a 4-week diet intervention study, healthy cognitively intact older adults who stuck to a low-saturated-fat, low-glycemic-index diet experienced decreases in cerebrospinal fluid (CSF) levels of β-amyloid 42, a biomarker of Alzheimer's disease risk.

They concluded that none of the screening tests for autism had high enough accuracy in terms of sensitivity, specificity, and high predictive value. Moreover, there was a serious lack of effective treatment available should such a diagnosis be madeLenea lungeste viata!
Concluzii serioase: lenea lungeste viata! (Tot invatam cate ceva nou... sau confirmam concluzii mai vechi!)
*Lenea lungeste viata! *
Persoanele care nu prea se inghesuie sa munceasca si care au oroare de
exercitiile fizice banuiau de multa vreme acest lucru, dar acum a fost
confirmat de oamenii de stiinta : lenea prelungeste viata.
Doi cercetatori germani, dr. Peter Axt si fiica sa, dr. Michaela
Axt-Gadermann, au publicat o carte ("Bucuria Lenii : Cum s-o lasi mai moale
si sa traiesti mai mult") in care explica pe larg faptul ca toti oamenii
poseda o cantitate limitata de "energie vitala" si ca viteza cu care este
consumata, determina precis speranta de viata a fiecarei persoane.
Cei doi mai spun ca activitatile care sunt mari consumatoare de
energie,precum "trasul de fiare" intr-o sala de forta, accelereaza
imbatranirea si fac organismul mai susceptibil la imbolnavire. "Un stil de
viata mai relaxat este important pentru sanatate...
Daca ai o viata stresanta si faci exercitii fizice in exces, organismul
produce hormoni care determina instalarea hipertensiunii",afirma
Axt-Gadermann.
Ea a adaugat ca una dintre diferentele-cheie intre oamenii mai lenesi si cei
hiperactivi este ca organismele mai active produc mai multi "radicali
liberi" molecule instabile de oxigen despre care se crede ca ar accelera
imbatranirea.
Mai mult, "lenea este, de asemenea, importanta pentru un sistem imunitar
sanatos pentru ca celulele specializate in apararea organismului sunt mai
puternice in conditii de relaxare decat in situatii de stres". Iar in timpul
relaxarii si metabolismul este mai lent, producandu-se mai putini radicali
liberi.
Atat Axt-Gadermann, 34 de ani, cat si tatal sau, in varsta de 65 de ani, au
fost alergatori de cursa lunga, ceea ce le permite sa sustina ca vorbesc in
cunostinta de cauza.
Totodata, ei afirma ca râsul este o alternativa mai sanatoasa decat
alergarea sau exercitiile fizice..
In carte, cei doi cercetatori mai spun ca lenea este foarte buna si pentru
creier. Asta pentru ca exercitiile fizice sau stresul duc la producerea unui
excedent de cortisol, un hormon care vatama neuronii si provoaca pierderi de
memorie si senilitate prematura.
*Nota personala : Bâtrânii nostrii spuneau despre o persoana lenesa : "Asta
traieste 100 de ani" si uite...s-a dovedit ca aveau dreptate*

May 17, 2011 (Washington, DC) — The long-term risk for prostate cancer can be

* munca la batrinete
Many workers benefit significantly from continuing to work into old age. Work is "medicine" -- even better than medicine for many. In
addition to providing economic security and often wider access to healthcare options, work enhances well-being, promotes social interaction, increases the variety and quality of life, and provides
many people with a sense of accomplishment and achievement. Although some older individuals work out of necessity, many report that they continue to work to contribute, or to "make a difference."
Almost all jobs help older people sustain and extend their physical activity level and support increased social engagement and larger support networks. Work provides accountability for many; an
absence from work may serve as the first sign to warn distant family that something is wrong with a loved one. Emerging evidence also suggests that work may improve brain health, sustain healthy
cognition, and protect memory

May 17, 2011 (Honolulu, Hawaii) — The prevalence of alcohol use disorders will increase substantially if proposed
revisions to diagnostic criteria for alcohol abuse and dependence contained in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), are adopted, a new study
suggests.

December 2, 2010 — A joint research project between Harvard University and University of Utah scientists has resulted in
the development of a new biological test for autism.
The test, which uses magnetic resonance imaging (MRI) to measure deviations in brain circuitry, is an objective way of identifying individuals with the disorder and could someday replace the subjective methods that are currently used
* Clozapine/clorpromazine
The study authors compared the 9-year outcomes of 160 individuals with treatment-naive, first-episode schizophrenia or
schizophreniform disorder treated in a mental health center in Beijing, China. They were initially randomly assigned to clozapine or chlorpromazine (with benztropine) treatment
for up to 2 years followed by up to an additional 7 years of naturalistic treatment. Individuals in both groups spent essentially equal amounts of time in remission during the follow-up
time period (78%). There were no significant differences on other measures of illness severity. There were no significant differences between the 2 groups on other secondary
efficacy outcomes. However, the clozapine group was more likely than the chlorpromazine group to remain on the medication to which they were originally assigned (26% vs 10%;

[PPIs] and histamine 2 receptor antagonists (H2RAs) are the most popular [acid-suppressive drugs] available, and millions of

potent drugs are used to treat various disorders, and indications for long-term maintenance therapy with this drug class continue to expand. The relationship between [acid-suppressive drug] use and

Advances in Adult ADHD
•Attention-deficit/hyperactivity disorder (ADHD) affects an estimated 4.4% of US adults, an incidence second only to major depression in the spectrum of psychiatric disorders. Despite this
high prevalence, less than 11% of these adults are treated. The economic and public health consequences of untreated ADHD are wide-ranging and include lower wages and a higher rate of risk-taking;
the prevalence of addictive, antisocial, and destructive behaviors in adults with ADHD is nearly twice that of the general population. Given that ADHD is a very treatable condition, it is essential
that healthcare professionals better understand the disorder's complexities and corresponding diagnostic and treatment techniques.
* schizofrenia se poate trata de la prodroame
Rabindra Tambyraja, MD: I would hazard a guess that some of the over-reliance on medication and skepticism toward psychosocial interventions stems from a belief that psychotic disorders are "worse"
than mood or anxiety disorders, and therefore require more "serious" treatments. Hopefully, my quotes show my thoughts about dismissing psychosocial treatments. There is evidence that high-conflict
environments can be associated with a faster progression of psychosis, so it's a worthy hypothesis that decreasing the conflict and increasing the strength of psychosocial support could have a
positive effect.
DMT - Molecula spiritului
Acest film documentar online este povestea DMT (sau dimetiltriptamina), un
compus simplu, găsit în natură, cu efect profund asupra conştiinţei umane.
Lansat în 2010 în Statene Unite ale Americii, documentarul are la bază
cercetările lui Rick Strassman, profesor de psihiatrite la Universitatea New
Mexico. DMT este o substanţă foarte simplă, un compus halucinogenic din familia
triptaminei, prezent în plante, în organismul unor mamifere, dar şi în
cel uman.
Deşi ştiinţa nu a reuşit să dea un răspuns cu privire la sursa sau
rolul acestei
substanţe, unii o consideră a fi "limbajul comun molecular", un mediator
spiritual natural.

1 Evaluarea antipsihoticelor(BJP)
Aims
To assess the clinical relevance of findings in the literature.
Method
A systematic review identified studies of antipsychotics that used the Brief Psychiatric Rating Scale (BPRS) and Positive and Negative Syndrome Scale (PANSS). A published method of translating these into Clinical Global Impression – Change scale (CGI–C) scores was used to measure clinical relevance.
Results
In total 98 data-sets were included in the BPRS analysis and 202 data-sets in the PANSS analysis. When aggregated scores were translated into notional CGI–C scores, most drugs reached 'minimal improvement' on the BPRS, but few reached that level for PANSS. This was true of both first- and second-generation drugs, including clozapine. Amisulpride and olanzapine had better than average CGI–C scores.
Conclusions
Our findings show improvements of limited clinical relevance. The CGI–C scores were better for the BPRS than for the PANSS.April 8, 2011 — For the first time, researchers have found that peripheral blood mononuclear cells express amyloid precursor protein

15. tratamentul bulimiei
Psychological treatments for bulimia and depression
Even when treatments have demonstrated efficacy in a specific disorder, the optimal manner in which to apply them can still remain unclear. Mitchell et al (pp. 391–397) studied a stepped care approach to treating bulimia – starting with a self-help technique, then going on to fluoxetine, and finally using cognitive–behavioural therapy (CBT), if patients are not responding to the earlier treatment. They found that this stepped care was superior to standard CBT augmented with fluoxetine at 1 year follow-up. At the end of treatment, a brief supervised self-help version of CBT, delivered by less experienced therapists and augmented with fluoxetine treatment, was as effective as a longer period of traditional CBT by expert therapists, with added fluoxetine. The stepped care approach was also likely to be more cost-effective. The value of family intervention in depression is highlighted by Shimazu et al (pp. 385–390): they found that time to relapse was significantly reduced after four sessions of a family psychoeducation intervention. Interestingly, these effects did not appear to be mediated by changes in familial expressed emotion and were achieved without the patient attending the sessions. An accompanying editorial by Colom (pp. 338–340) reviews the benefits of psychoeducation and also refers to the important, but often neglected, necessary multiple components of effective psychoeducation. He is clear that psychoeducation is not the mere provision of educational material, general guidance on prevention, or advice on crisis management, but is a more interactive process of developing a shared understanding of the management of a patient s condition. Towards this end, he sets out some of the necessary environmental conditions for effective psychoeducation to flourish.
