Еще двух пациентов удалось вывести из комы при помощи ультразвука

Пять лет назад команда ученых из Калифорнийского университета под руководством профессора Мартина Монти впервые применила направленное ультразвуковое излучение для стимуляции мозга человека в коме. Они сфокусировали его на таламусе, центральном органе мозга, и сразу добились успеха – 25-летний мужчина пришел в сознание, смог разговаривать и отвечать на вопросы. Однако он и так шел на поправку, поэтому результаты эксперимента считались спорными.

После доработки методики команда Монти провела три новых операции. Они сконструировали компактный излучатель размером со смартфон, который размещается сбоку от головы пациента. Обработка мозга излучением низкой интенсивности длится 10 минут, 10 сеансов по 30 секунд каждый. Суммарная излученная энергия меньше, чем в традиционном аппарате УЗИ, поэтому такое воздействие безопасно.

Первым пациентом стал 56-летний мужчина, который провел в коме 14 месяцев после инсульта. После первого воздействия ультразвуком он смог поймать брошенный мяч и узнать людей на фото, после второго – отвечать на вопросы и писать текст. Второй пациент, женщина 50 лет, провела в коме 2,5 года после остановки сердца. Ее результаты хуже – она пришла в сознание и смогла узнать простые предметы, вроде расчески и ручки, но не более того.

Увы, третий пациент, 58-летний мужчина, который после ДТП пролежал в коме 5,5 лет, на воздействие ультразвуком не отреагировал. Видимо, деградация нервной системы пациента в коматозном состоянии со временем приобретает слишком сложный характер. С другой стороны, сама возможность выведения людей из него всего за несколько дней очень обнадеживает ученых.

2 КОММЕНТАРИИ

  1. Similar to different peptides that improve growth hormone ranges, we now
    have observed BPC 157 to stimulate collagen synthesis, inducing anti-aging effects.
    BPC-157 is derived from human gastric juice and is a peptide drug composed of 15 amino acids.

    However, each user’s physical situation and structure are different,
    and some side effects might occur, similar to nausea, headache and fatigue.

    BPC 157 was added to cells at the concentrations of zero (control group),
    0.1, 0.25 and 0.5 μg/mL. After incubation at 37 °C in a humidified ambiance of 5% CO2/95% air for 1, 2 and
    three days, cells were collected for analysis of the
    expression of progress hormone receptors by RT PCR and Western blotting.

    Progress hormone increased the PCNA gene expression in BPC 157-treated tendon fibroblasts.
    Tendon fibroblasts at 50%–60% confluency had been pretreated with BPC 157 at concentrations
    of 0, 0.1, 0.25, 0.5 μg/mL for twenty-four h (A) or 0.5 μg/mL
    for one to three days (B).
    BPC 157 also protects nerve cells preventing memory loss
    and harm in lab checks. This means it may help mind well being by
    making neurons extra resilient and slicing down on oxidative stress.
    BPC 157 represents an artificial peptide structure consisting of
    15 amino acids, initially derived from a protein present in gastric tissue.
    Laboratory investigations, significantly those performed with animal models, counsel this compound possesses fascinating properties
    worthy of scientific examination. Its technical classification as a steady gastric pentadecapeptide underscores its significance inside the analysis community.
    Analysis means that BPC 157 could aid in muscle restore and tendon outgrowth,
    probably dashing up recovery occasions for
    athletes.
    While the findings are promising, continued research is necessary to completely perceive the therapeutic
    results of BPC 157. Wholesale Peptide remains dedicated to
    providing high-quality peptides for analysis to help additional research in this space.
    Nonetheless, it’s essential to say that prime levels of nitric oxide can result in undesirable processes, corresponding
    to inhibiting heme insertion in hemoglobin and affecting
    mitochondrial respiration. This underscores the
    essential function of careful analysis, as it has been suggested
    to steadiness the beneficial and potential antagonistic results.

    Interestingly, a latest study confirmed that the energy of the
    lower a part of healthy men has also been elevated by growth hormone therapy and a scientific trial is now present process for older population. Progress
    hormone was also reported to have results of migration and adhesion of
    different cells. Taub et al. reported that by way of chemokinetic impact, growth hormone
    may significantly induce the migration of resting
    and activated human T cells [31]. Savino also reported that development hormone has a role in migration of developing thymocytes [32].

    Taking BPC-157 orally comes with unique challenges
    because of its interplay along with your digestive system.
    The mostly reported unwanted effects of BPC-157 are relatively gentle and infrequently
    resolve on their own within a couple of days. However, human physiology can differ considerably from that of rodents and
    different lab animals. The World Anti-Doping Agency (WADA) has added it to
    its listing of banned substances underneath the «Non-approved Substances» category in 2022 as a
    end result of it might give athletes an unfair advantage in recovery pace.

    For additional exploration and validation of the data mentioned on BPC 157 and TB-500, check with reputable sources
    similar to NIH, Forbes, and research research by consultants like
    Dr. Jason Phan NMD. When used together, they synergistically enhance their individual effects, resulting in a stronger therapeutic response.
    We are committed to offering respectful, inclusive services and work environments
    where all individuals really feel accepted, safe,
    affirmed and celebrated.
    Athletes, particularly, discover BPC-157 helpful for promoting rapid restoration from injuries.
    It aids in rebuilding damaged connective tissues and strengthening blood vessels, finally enhancing total bodily resilience and efficiency on the sector.

    They are grasp controllers of capabilities throughout the physique, including hormone manufacturing, cell signaling, and cell-to-cell communication. The peptide binds to the
    receptor of a selected cell, causes that chemical reaction, and
    then goes away. Peptides have a really brief half-life, so
    they are thought to be very protected. This is doubtless considered one of
    the key variations between peptides and hormones, like steroids, which stay round in your body
    a lengthy time and cause every kind of results, each good and bad.

    Additional BPC 157 peptide has been discovered to profit smooth muscle
    and skeletal muscle restore following harm non return to baseline values and as properly.
    Has many other healing possibilities within the body, the intestine, brain and mood.
    BPC 157 capsules show promise for therapeutic tissues,
    soothing the gut, and muscle restoration all based mostly on early lab research.

    Collectively, these findings suggest a two-part mannequin for how TB-500 would possibly perform as an anti-inflammatory
    agent in lab studies. First, it raises microRNA-146a
    to curb the necessary thing adaptor proteins IRAK1 and TRAF6.

    Second, it reshapes MAPK signaling in a way which will steer
    cells away from acute inflammation and towards recovery.

    Based on the obtainable data, BPC-157 seems to be extra completely researched when it comes to its potential for the healing
    of muscle, tendon, and bone injuries [29, 30, 31, 32].
    TB-500 and BPC-157 have undergone intensive analysis for
    varied wound therapeutic functions, together with within the therapeutic of skin ulcers, corneal abrasions, and recovery following gastrointestinal surgery.
    In this part, we will break the newest scientific data on the benefits
    and analysis purposes of TB-500 and BPC-157.
