Metodo Montessori: una educazione per la pace
Nella Giornata internazionale della Pace, non può di certo mancare un riferimento all’opera di Maria Montessori.
Divenuta famosa per il suo impegno nell’educazione, la Dottoressa ha dedicato però anche grandissima attenzione a temi quali la questione delle donne, il voto politico per le stesse, le condizioni di svantaggio sociale delle classi più deboli, il problema dell’educazione dei bambini con deficit cognitivi e non.
La Pace e le vie per costruirla sono state sempre elemento costituivo della sua riflessione e fu proprio attraverso il suo lavoro con i bambini che ella arrivò alla soluzione: l’educazione è l’arma della Pace.
Con il suo lavoro, ella ci fa capire le guerre dipendono solo in extremis da squilibri economici, mentre le cause più profonde sono da riscontrare già in interventi educativi inadeguati nell’infanzia. La pace è dunque innanzitutto un problema pedagogico, e la responsabilità ultima della sua realizzazione è dell’educazione.
La politica può solo evitare le guerre, ottenere che i conflitti tra i popoli si risolvano attraverso negoziati piuttosto che attraverso la violenza, ma non può costruire la pace.
Ma quale educazione può davvero creare le premesse per un mondo di pace?
Di certo, non l’approccio educativo tradizionale, basato sull’idea che sia l’adulto a plasmare il bambino “come fosse cera molle“. Per tempo immane esso ha piuttosto portato alla formazione di individui dipendenti, eterodiretti, competitivi e alla ricerca continua di approvazione.
Maria Montessori ci parla invece della necessità di una educazione nuova, che porti alla formazione di un uomo nuovo. Una educazione che ponga il soggetto che apprende in una posizione attiva, che tragga da egli stesso i dettami necessari alla propria definizione:
Il bambino non è debole e povero; il bambino è il padre dell’umanità e della civilizzazione, è il nostro maestro anche nei riguardi della sua educazione. Questa non è una esaltazione fuori misura dell’infanzia, è una grande verità.“
Se dunque è vero che l’educazione ha inizio dalla nascita, l’adulto dovrebbe impegnarsi a compiere un profondo lavoro di trasformazione di sé e fare un necessario passo indietro. Ciò significherà lasciar emergere il “maestro interiore” che è nel bambino, lasciare che sia esso la nostra guida nel predisporre l’ambiente e le giuste risorse per lo sviluppo.
Una educazione così concepita consente al bambino di liberare tutto il proprio potenziale e, quindi, di divenire un adulto libero, capace di autodirigersi nella vita, autonomo eppure in perfetta comunione con gli altri, artefice un domani di un mondo migliore.
Senza voler semplificare eccessivamente una questione tanto complessa, il mio invito è a riflettere su queste idee. La rivoluzione auspicata da Maria Montessori è attuabile, ma necessita di impegno e grande responsabilità da parte di tutta la società. I governi dovrebbero rivedere le loro priorità, assegnando all’educazione l’importanza che essa, a pieno titolo, merita. Ma anche il singolo individuo dovrebbe impegnarsi a lavorare su di sé e a diventare egli stesso motore del cambiamento.
La vera difesa dei popoli non può poggiare sulle armi: giacché le guerre … non potranno mai assicurare la pace e la prosperità di nessun popolo, finché non si ricorrerà a questo grande armamento della pace che è l’educazione”

Present attempts at medical application of MSTN inhibitors have encountered challenges with drug
design and illness functions. Muscular dystrophies, the first focus of
MSTN-inhibition therapeutics so far, stem from genetic-based pathways that will
not be easily remedied solely by inhibiting MSTN or augmenting skeletal muscle mass.
Future applications of MSTN inhibition should contemplate the constraints of targeting skeletal muscle mass and discover more suitable disease purposes.
These approaches may mitigate the challenges posed
by the low MSTN levels in patients with extreme muscular dystrophy, which may
in any other case reduce the effectiveness of MSTN inhibitors.
There are additionally future application potentialities
in non-diseased sufferers, like focusing on MSTN to guard in opposition to
muscle and bone mass loss throughout house flight [155].
Regardless of application, future analysis on MSTN inhibitors should prioritize the
event of specific inhibitor designs to mitigate unwanted side effects brought on by cross-reactivity.
The control group had a larger range and interquartile range in LOAD scores for all three time
factors in contrast with the remedy group (Table 2).
The resulting large variance in the control group in contrast with the therapy
group doubtless is the reason for a statistical
distinction within teams however not between groups.
Therefore, this statistically significant distinction within the therapy group could not mirror a clinically relevant change.
Moreover, it has been proven that anionic liposomes can shield ghrelin from enzymatic breakdown by trypsin and carboxylesterase.
Coating ghrelin with N-(2-hydroxy) propyl-3-trimethyl ammonium chitosan chloride enhanced mucin adsorption capacity (22.9%), with improved
permeability via Calu3 epithelial monolayers recovering 10.8% of ghrelin in the basal compartment versus nonloaded ghrelin was used.
Anionic liposomes coated with chitosan in dry powder form exhibited better mucin adhesion, ghrelin loadings, and
enzymatic protection in opposition to trypsin, and decreased
ghrelin degradation throughout storage at room temperature (Howick et al., 2018).
Every of these components presents unique benefits that may aid
in muscle growth both by immediately inhibiting
myostatin or by supporting muscle well being and decreasing
the elements that can limit development.
Intransgenic mice overexpressing FST exhibit decreased high
quality of skeleton and tibia fractures in distinction to myostatin null mice that
show enhanced BMD with out fractures (Fig. 2) [6].
Above all, these findings strongly emphasize the significance of goal
specificity when growing myostatin inhibitors, especially those supposed for
long-term remedy, to attenuate potential adverse results in several tissues.
ACE-011 in a section 1 medical trial conducted on healthy postmenopausal women additionally increased hematocrit, Hb, and
RBC ranges [56]. These results have evoked a substantial interest in ACE-011, initially developed to deal with bone-loss disorders, as a potential therapeutic option for sufferers with anemia and diseases involving ineffective erythropoiesis.
Furthermore, MYF5, MYOD, MYOG, and MRF4 are crucially concerned in directing
MSCs to regenerate SM [34]. MSTN sustains the quiescent
state of MSCs by negatively regulating Pax7 and its absence ends in the proliferation of active
MSCs [35,36]. Interestingly, following muscle injury, Ac-MIF1
and Ac-MIF2-NH2 peptides induced muscle regeneration by inducing the protein/mRNA
expression of Pax7, MYOD, MYOG, and MYL2. The observed will increase
in Pax7 and MYOD expression might have been as a result of
increased MSC numbers and subsequent myogenesis because of MSTN inhibition. In addition, reduced ACVRIIB protein expression after Ac-MIF2-NH2 therapy during muscle regeneration indicated that Ac-MIF2-NH2 peptide inhibited MSTN by lowering MSTN binding to ACVRIIB.
Altogether, these observations suggest Ac-MIF1 and Ac-MIF2-NH2 peptides induce muscle regenerative capability
in injured muscles. In previous research, we confirmed FMOD regulates MSTN expression by interacting with it and
reducing ACVRIIB to MSTN binding affinity, and that lipid accumulation in myoblasts was elevated in FMOD knockdown cells [10,18].
Myostatin inhibition in the case of the adult mice involves injection of man-made or natural myostatin inhibitors similar
to Follistatin. Even extra advantageous to some persons are the potential medical
purposes for treating (some) muscle-wasting illnesses or conditions
where retaining muscle mass is problematic.
Regardless Of the dearth of evidence, certain companies claim their
workout dietary supplements additionally act as myostatin inhibitors.
Creatine not solely powers workouts however can not directly have an effect on myostatin expression by bolstering muscle hypertrophy.
This is the place epicatechin supplements can turn out to be useful to beat
the variability in dietary sources — however we’re getting
forward of ourselves right here. We just want to underscore that
most dietary supplements, like epicatechin dietary supplements, aren’t the only solution to
rising muscle progress. They’re not magic pills however
could be a half of a holistic strategy for fitness targets.
If you wish to get actually technical, it’s a half of the TGF-β household and works by blocking sure pathways that set off muscle progress, such as the IGF-1/PI3K/Akt/mTOR
pathway [1]. Each of those supplements incorporates distinctive ingredients that help them stand out from the remaining.
They are designed to maximise muscle progress, improve strength, and enhance total bodily efficiency.
This information will take you on a journey via the science and benefits of myostatin inhibitors, highlight prime products in the market, and
give you the inside scoop on the method to maximize their results.
This is essential as a result of past a sure size, including extra mass to muscular
tissues doesn’t really make them stronger – and muscles which are too large are additionally
more susceptible to break. Over-developed muscular
tissues also can get in the way of other essential organs, lowering
their dimension and impairing their capabilities [1, 2].
PureRawz offers a high-quality peptide answer that’s perfect for these exploring the benefits
of myostatin inhibitors.
They are also typically used to deal with different
situations, such as anxiousness and long-term ache, particularly nerve pain. All animal experiments and methods
were carried out in accordance with ARRIVE pointers and rules.
All animal experiments have been performed
in accordance with the protocols and rules accredited
by the Ethics Committee of Jiangxi College of Science and Technology (the approval quantity was No.
IACUC Y202445).
Secondly, epicatechin supplementation might improve muscle protein synthesis,
exercise endurance capacity, and relative peak anaerobic energy
via several proposed pathways that we are going to focus on beneath [9].
37 recreationally educated faculty aged males volunteered to take part on this examine
and were divided equally into three groups receiving a placebo macronutrient matched control, 10
or 30 grams of MYOX (MyoS Corp) supplementation for 8 weeks.
DXA determined lean mass, ultrasonography decided
muscle mass, and lower and upper physique strength had been measured pre and publish 12 weeks of coaching.
Nonetheless, the research lacked dietary records, making it
unclear if members consumed extra protein and calories,
which may lead to elevated muscle development. Personally,
I, together with many others, purchased this product and located it lacking in delivering the promised results.
In fact, some analysis implies that myostatin actively triggers muscle atrophy (muscle wasting)
when development triggers are abnormally reduced such as in periods of prolonged inactivity like
hospital bed rest, and persistent muscle disuse atrophy.
Secondly, scientists think about that myostatin inhibition may
also prevent muscle loss that occurs as a end result of different diseases.
For instance, deleting the genes concerned in producing myostatin within the hearts
of mice prevented the severe muscle and weight loss caused by heart failure [11].
Under is an inventory of pathways myostatin inhibition may target,
primarily based on the obtainable research.
In a phase half scientific trial of patients with Becker muscular dystrophy, direct bilateral intramuscular quadriceps injections (3×1011
vg/kg/leg or 6×1011 vg/kg/leg) of rAAV1.CMV.huFollistatin 344 significantly improved
6-min walking distance in 4 out of 6 sufferers [84]. A section half study
performed on sufferers with DMD, in which a higher dose (2.4×1012 vg/kg/patient) of rAAV1.CMV.huFollistatin344 was delivered to gluteal muscular tissues, quadriceps,
and tibialis anterior, is also completed and beneath analysis.
Ramatercept (ACE-031) is a soluble type of ACVR2B
developed by Acceleron Pharma for the remedy of DMD.
Trevogrumab (REGN-1033), developed by Regeneron Prescribed Drugs Inc.,
is a monoclonal anti-myostatin antibody designed to
treat patients with sarcopenia (phase 2 accomplished in 2015).
REGN-1033, which selectively inhibits pro-, latent,
and mature myostatin without binding GDF11 or activin A, effectively enhanced skeletal muscle mass
and improved isometric pressure manufacturing in young and aged mice [67].
Efficacy evaluations of the finished phase 2 clinical
trial with the first endpoint of % change in lean body mass in patients with sarcopenia are presently ongoing.
ACE-2494, also developed by Acceleron Pharma as a possible therapeutic agent for bone fragility and muscle-wasting ailments, is a soluble ACVR2B receptor modified to reduce vascular unwanted effects induced by BMP9/10 inhibition [50].
However, it could be very important notice that using myostatin inhibitors in enhancing athletic efficiency
is taken into account unethical and will have antagonistic well being effects.
Myostatin (or growth differentiation factor-8, GDF-8)
is a unfavorable regulator of muscle development
and a member of the transforming development factor-β
family [7]. Numerous molecular mechanisms regulating protein synthesis and degradation are
influenced by myostatin [8]. Myostatin also negatively regulates the activation and self-renewal of satellite cells (SC)
by inhibiting the progress of SC into the S phase of the cell cycle [9].
In addition, myostatin reduces IGF-Akt pathway activity leading to decreased protein synthesis initiation and increased translocation of Forkhead field protein O1 (Foxo1) into the nucleus.
Previous studies reported an increased myostatin mRNA expression in skeletal muscle after 5
days of single-leg immobilization [10] and a rise in myostatin mRNA and protein expression after 3 days of unilateral lower limb suspension in wholesome young males [11].
Whereas Jones et al. [12] showed no change in myostatin mRNA expression after 2-wk of single-leg immobilization, though there was an increased tendency of myostatin mRNA.
Inhibiting MSTN might have therapeutic applications in selling bone
regeneration and healing in bone fractures, osteoporosis,
rheumatoid arthritis, and osteoarthritis.
In mice, administration of recombinant MSTN propeptide
improved fracture therapeutic in a fibula osteotomy mannequin [150].
Moreover, remedy of young mice with ActRIIB-Fc led to increased
bone mass [151].
Just Lately, we carried out a VS-based evaluation on known muscle-enhancing
natural compounds for MSTN inhibitory activity and recognized curcumin and gingerol as candidates (Baig et al., 2017).
Undoubtedly, there are limitations of the VS approach that should be taken into consideration. The prevalence of stereochemical and
valence errors in biochemical compound libraries could probably result in inviable molecules
(Williams et al., 2012; Santana et al., 2021).
This study examined 12-weeks of resistance coaching and cystoseira canariensis supplementation on serum
ranges of myostatin and muscle power and body composition in twenty-two untrained males.
Coaching consisted of three days per week utilizing three sets of 6
to 8 repetitions at 85–90% 1 RM. The researchers concluded that 12-weeks of heavy resistance coaching and 1200 mg/d of
cystoseira canariensis supplementation gave the impression to
be ineffective at inhibiting serum myostatin and growing muscle strength and mass or lowering fat mass.
The clarification for the dramatic results in animals while no noticed results in people in all probability lies
in the truth that myostatin particular antibodies were used
within the animal model, whereas human models
use sulfo-polysaccharides which are solely advertised to bind to myostatin.
Outcomes of this study support this prior report in that CSP3 supplementation had no
significant effects on body composition, training variations, or
markers of anabolic/catabolic status in resistance-trained men.
In 2004, Wyeth Pharmaceuticals (now owned by Pfizer) developed
the monoclonal anti-MSTN antibody MYO-029, the primary MSTN inhibitor to enter
scientific trials. MYO-029 binds to mature MSTN, thereby stopping its interplay with ActRIIA/B receptors.
Muscle cells possess an innate mechanism to control their own progress,
and on the heart of this regulation stands myostatin. This protein acts as a pure limiter, stopping muscles from reaching their full potential.
However what if we may deactivate myostatin and pave
the way for unparalleled muscle mass and strength?
This tantalizing idea has captivated scientists worldwide,
leading to a relentless quest for myostatin inhibitors.
In the muscles, extra blood circulate means more nutrients for the cells to use so as to grow and multiply.
Researchers reported ~96 mg of epicatechin within the chocolate, however the exact stereoisomer
was not reported (+ or –). Other researchers found no benefit to ingesting
flavanol-containing (specific flavanols not reported) cocoa beverages on indices of muscle
harm after downhill working (19). Regardless Of promising proof in rodent fashions,
the paucity of evidence involving (–)-epicatechin supplementation in people topics in combination with train training is inadequate for interpretation as to if
and how flavanols modulate exercise diversifications. As A
End Result Of of the aforementioned observations with (–)-epicatechin supplementation, it has been advised
that it could be useful as a method to increase exercise diversifications (13).
Fifteen days of (–)-epicatechin supplementation alone resulted in increased train efficiency, reduced
muscle fatigue, elevated muscle capillarity and
elevated mitochondrial biogenesis in mice (14). In mice selectively bred for
low working capacity, 30 days of (–)-epicatechin supplementation successfully
increased skeletal muscle capillarity and mitochondrial biogenesis (15).
In one other research, (–)-epicatechin supplementation in mice, together with treadmill train over the
course of 8 weeks, elevated angiogenesis
and mitochondrial biogenesis (16).
During this session, each participant performed a apply trial for the Wingate anaerobic cycle test to become conversant in the calls for of
the check. Paul Michael Levesque, better often identified
as Triple H, has ruled the world of WWE for a couple of years.
Paul Levesque gave us “Connecticut Blueblood,” who later became generally recognized as Hunter Hearst Helmsley, shortened as Triple
H…. This group is designed for people thinking about
DIY biology, typically referred to as biohacking. Members can collaborate,
share information, and discover topics such as genetic engineering, experimental pharmacology, life extension, longevity, and bio-enhancement.
This space encourages scientific inquiry and sensible experimentation in accessible, hands-on ways.
When mixed with a correct food regimen and train routine, supplements containing these ingredients can help break through development
plateaus and improve each muscle measurement and power.
At All Times consult with a healthcare professional earlier than beginning any new
complement routine, especially when you have underlying health circumstances or are taking other drugs.
Stamulumab (Myo-29), developed by Wyeth Prescription Drugs (now Pfizer), is the first myostatin inhibitor to
progress to clinical trials. Myo-29 is a monoclonal anti-myostatin anti-body designed to treat patients with
Becker muscular dystrophy, facioscapulohumeral
muscular dystrophy (FSHD), or limb-girdle muscular dystrophy
(LGMD). Despite encouraging results of the preclinical studies
[59] and safety profile, Myo-29 failed to indicate important enhancements in muscle energy or function doubtless as
a end result of high price of clearance [60], which halted its additional improvement.
Myostatin-induced phosphorylation of Smad3 interferes with the exercise of MyoD, a master transcription consider myogenesis, impairing
myoblast differentiation [35].
