Request or randomized kisses meme || No longer accepting

@technodromes sent: 'I want the K' (yeeting Bishop Rick's way. Confused croaking and burbling intensifies)

{ Randomly generated number: 6. Gentle Peck }

It isn't often that you can find Bishop outside his Norman-Body. While Krang and Subprime are more than content to use their walker or pod respectively, the other Utrom seems to favour the android, even when he is in the company of the Technodrome crew. Morty says that it's both out of habit and because it makes the alien feel like he fits more, while Rick simply calls it "bullshit behaviour", which is the lazy label he assigned to all behaviours he can't be bothered to decipher.

Today, however, is one of the occasions when the Kraang had decided to forgo his human-looking disguise and to move around in his pod. His teen friend probably had something to do with this choice, but Rick doesn't care enough to speculate. All that matters is that this is the perfect chance to literally get his hands on Bishop's real body and he isn't going to waste it.

So, he lurks around in the room where Morty is trying to explain to Bishop this or that human tradition, fixing up some device for Krang as he waits for the right moment to strike. It's a win-win, because the repairs he needs to do is simple enough not to require his full attention, which means that he can easily pretend to be busy while appeasing the aspiring overlord.

...He has no idea of what has gotten into the goddamn Utrom lately, but he's been busting his balls trying to get him to fix his shit, even more than he usually does.

Eventually, his effort to be patient is rewarded when his grandson stands up and leaves the room, most likely to retrieve something that can help him dispel Bishop's obvious confusion over whatever they have been discussing. Rick has to bite back a derisive scoff. Between the Utrom's cluelessness and Morty's verbal clumsiness is no surprise that their conversation hasn't gotten anywhere yet.

Under other circumstances, he might have throw out a mocking comment, but right now he needs the element of surprise.

So, as soon as the automatic doors have closed behind the teen, he makes his move, exploiting the fact that Bishop is still too busy squinting at his tablet to notice him approaching from behind.

Rick's hands close around the sides of the pod without a warning and he spins it around, so that he and the Kraang are face to face. His lips are curled in a predatory grin, and he's almost looking like he's getting read to feast on the poor alien.

"C-C'mere, bubblegum.~"

Once again without waiting for a reaction, he pries the Utrom away from the pod, bringing him closer to his own face. His smirk widens, showing too much teeth for everyone's comfort and strengthening the impression that he's about to do something unspeakable.

However, instead of a lick or a forceful kiss or, even worse, a bite as one would expect from such an act, what Bishop gets is a gentle, even if perhaps a little too slobbery, smooch between his eyes, right under the spot where his interhemispheric fissure begins.

When he breaks away, Rick's expression has turned from rapacious to smug, showing how pleased with himself he is with the prank he had just played. Snickering in delighted amusement, he sets the Kraang back in his pod, giving him a light tap on the top of his brain-like body, before shoving his hands hands in his pockets and heading out of the room, still laughing to himself.

Improving results in cerebral palsy with early intercession: new translational methodologies

Cerebral paralysis (CP) is characterized as a gathering of the perpetual issue of the advancement of development and stance, causing movement constraint, credited to non-dynamic unsettling influences happening in the creating fetal or newborn child mind. Sores to the sensor engine cortex, subcortical axon tracts, and subplot are regularly embroiled, with other engine and non-engine territories every now and again additionally influenced. The etiology is unpredictable and frequently multifactorial; causes incorporate hypoxia, stroke, contamination, injury, and hereditary variables. Before the second's over trimester, corticospinal axons have attacked the spinal dark issue and thalamic afferents the upper layers of the neocortex. These frameworks experience movement subordinate improvement. After early cerebrum damage, plummeting pathways are disturbed, with unusual advancement of reflex and corticospinal hardware. Development variations from the norm are at first unpretentious yet grow in this manner. Abnormal post-injury pliancy without a doubt adds to CP. It is deluding to assume that formative components are self-reparative. The test is to comprehend the movement subordinate calibrating of neural hardware amid typical improvement and advance attractive pliancy while restricting unwanted impacts following formative sores. Nevertheless, before proposing intercessions, we need to improve our result expectation abilities.

Cerebral palsy influences 2/1000 live births: its pervasiveness is a few times more prominent than spinal line damage (SCI) and amyotrophic sidelong sclerosis (ALS), which influence the corticospinal framework. In any case, a Web of Science writing look for 2010– 2014 utilizing the expressions "cerebral palsy" (barring supranuclear palsy), "spinal line damage," and "amyotrophic parallel sclerosis" returned fewer distributions for CP (6653) than SCI (16147) or ALS (8258). For the lead diaries Nature Neuroscience and Neuron, the thing that matters was more noteworthy: only one return for CP contrasted and 39 for SCI and 63 for ALS. Along these lines, CP (Cerebral Palsy) which causes deep-rooted and regularly extreme incapacity is under-examined contrasted and different conditions that connect with neuroscientists and nervous system specialists. We proposed a" cerebral palsy treatment subject" on improving results in CP with early intercession, as a discussion to advance CP-related research. We included creators with skill extending from flagging pathways through useful imaging and neurophysiology to non-obtrusive mediations in people. Articles incorporate long and short audits, unique research, and assessment pieces from fundamental researchers and clinicians. We accomplished our point in covering the forecast of results of pre-and pre-birth injuries, fundamental research in creature models and human subjects, and thoughts for, and preliminaries of, early intercessions.

Dr. Jitendra Jain sets the scene with a far-reaching survey abridging early mental health and talking about the impact of injuries and suggestions for early analysis and intercession audit improvements in development acknowledgment innovation for arranging unconstrained general developments in high-hazard newborn children. Whom center around the utilization of instrumented toys further proceed with this subject of innovation helped evaluation and robot-helped appraisal devices with practical MRI so utilitarian mind action can be mapped in wellbeing and infection even in early stages. Adopting an alternate strategy to early location, investigate the potential estimation of two serum biomarkers of cerebrum harm and neurodevelopment results in neonates with hypoxic-ischemic encephalopathy (HIE), in particular, UCH-LI and GFAP.

We got various fundamental research articles identifying with early cerebrum damage. Demonstrate that the expansion in neural antecedent cell development and multiplication in the subventricular zone after damage relies upon insulin-like development factor receptor motioning just as EGRF. They examine how the idea of the way of life medium utilized could have darkened this imperative finding up to this point. Again, at a flagging pathway level, Frisch considers the job of adenosine monophosphate kinase (AMPK) in instigating versatile fetal mind shut down and smothering master fiery reactions about exacerbating scholarly community amid work. This supposition paper goes with the article, which investigates in an ovine model the overwhelming connection between going before endless fetal hypoxia, intense and intensifying acidosis, timing and span of versatile cerebrum shutdown, and the level of mind aggravation. They recommend that EEG checking notwithstanding fetal pulse observing amid work may recognize prior those babies in danger of creating extreme acidosis. The ovine model sheds light on the human circumstance yet as ever; extrapolations between species must be finished with an alert. Address this issue in detail in a survey of the appropriateness of different creature models for testing early mediation approaches in CP.

Moving from physiology to histology and point-by-point longitudinal neuroimaging. Describe white issue injuries in preterm newborn children as far as the formative elements of "cell compartments in the cerebral divider," exhibiting how if the exact area and timing of the affront are known, the axonal pathways influenced can be anticipated. Mackey et al. additionally use neuroimaging to get the result, however about built up one-sided CP. In this setting, dissemination weighted MRI-based partial anisotropy in the back appendage of the inside case relates to upper appendage practical evaluations. They additionally show deficiencies in intracortical and interhemispheric restraint in those with poor upper appendage work.

We additionally requested articles on early mediation approaches. Two of these secured cell treatment. Gonzales-Portillo et al. investigate the potential for undeveloped cell treatment in neonatal HIE and the exceptional clinical issues to be tended to, while Li et al. talk about umbilical line platelet treatments in preterm newborn children, concentrating on white issue damage. The other two articles address non-obtrusive methodologies in babies with one-sided cerebrum harm survey current information of corticospinal tract improvement including hereditary and movement subordinate impacts and portray interventional approaches conceivably pertinent to hemiplegic CP. Finally, take a clinical stance, portraying the issues looked in hemiplegic CP, customary ways to deal with the executives and their constraints, and mediations as of now under scrutiny in newborn children.

We thank everybody who has bolstered this undertaking by submitting or surveying original copies. We trust this Research Topic will fill its need of showing a portion of the captivating advances in CP research, and raising the profile of this essential condition to advance further examination, at last, to serve those influenced.

Quantitative anatomical comparison of the ipsilateral and contralateral interhemispheric transcallosal approaches to the lateral ventricle

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe best approach to deep-seated lateral and third ventricle lesions is a function of lesion characteristics, location, and relationship to the ventricles. The authors sought to examine and compare angles of attack and surgical freedom of anterior ipsilateral and contralateral interhemispheric transcallosal approaches to the frontal horn of the lateral ventricle using human cadaveric head dissections. Illustrative clinical experiences with a contralateral interhemispheric transcallosal approach and an anterior interhemispheric transcallosal transchoroidal approach are also related.METHODSFive formalin-fixed human cadaveric heads (10 sides) were examined microsurgically. CT and MRI scans obtained before dissection were uploaded and fused into the navigation system. The authors performed contralateral and ipsilateral transcallosal approaches to the lateral ventricle. Using the navigation system, they measured areas of exposure, surgical freedom, angles of attack, and angle of view to the surgical surface. Two clinical cases are described.RESULTSThe exposed areas of the ipsilateral (mean [± SD] 313.8 ± 85.0 mm2) and contralateral (344 ± 87.73 mm2) interhemispheric approaches were not significantly different (p = 0.12). Surgical freedom and vertical angles of attack were significantly larger for the contralateral approach to the most midsuperior reachable point (p = 0.02 and p = 0.01, respectively) and to the posterosuperior (p = 0.02 and p = 0.04) and central (p = 0.04 and p = 0.02) regions of the lateral wall of the lateral ventricle. Surgical freedom and vertical angles of attack to central and anterior points on the floor of the lateral ventricle did not differ significantly with approach. The angle to the surface of the caudate head region was less steep for the contralateral (135.6° ± 15.6°) than for the ipsilateral (152.0° ± 13.6°) approach (p = 0.02).CONCLUSIONSThe anterior contralateral interhemispheric transcallosal approach provided a more expansive exposure to the lower two-thirds of the lateral ventricle and striothalamocapsular region. In normal-sized ventricles, the foramen of Monro and the choroidal fissure were better visualized through the lateral ventricle ipsilateral to the craniotomy than through the contralateral approach. from # All Medicine by Alexandros G.

Endoscopic approach via the interhemispheric fissure: the role of an endoscope in a surgical case of multiple falcine lesions

Endoscopic approach via the interhemispheric fissure: the role of an endoscope in a surgical case of multiple falcine lesions

Acta Neurochir (2017) 159:1243–1246

For treating a patient with multiple falcine and parasagittal lesions, we believe that it is beneficial to resect the maximum possible number of lesions during one operation, even if some lesions are asymptomatic. This practice can potentially reduce the total number of operations during a patient’s lifetime.
