Abstract:

The human brain is a large-scale complex network whose function relies on the interaction between its various regions. Recent studies of the human brain connectivity using resting-state/sleep functional magnetic resonance imaging (rsfMRI), diffusion tensor imaging (DTI), and, more recently, diffusion tensor spectroscopic imaging (DSI) data have provided deeper insight on the organization of structural and functional brain networks that continuously share information. Brain's energy is largely consumed at rest during spontaneous neuronal activity (~20%), while task-related increases in metabolism energy are minor (<5%). Spontaneous ultralow-frequency fluctuations in BOLD-based rsfMRI signals (<0.01Hz) at the level of large-scale neural systems are not noise, but orderly and organized in a series of functional networks that permanently maintain a high level of temporal coherence among brain areas that are structurally segregated and functionally linked in resting state networks (RSNs). There is evidence suggesting that such signals permit to extract information about the connectivity and functionality of specific networks. It is also documented that functional connectivity reflects the underlying structural connectivity, which, at rest undergoes specific alterations in several neurological and psychiatric disorders. Human brain function imaged by rsfMRI allows accessing both sides of human mind-brain interface (subjective experience and objective observations). As such, functional neuroimaging moves onto new potential applications like reading the brain states, discriminate neurological dysfunctions (if any), artificial intelligence (AI), brain-computer interfaces (BCI), lie detection, and alike. The presentation aims to review and evaluate the most current approaches for early detection and classification of various forms of dementia, particularly among syndromes with relatively similar behavioral effects, as well as stages in a given syndrome, based on modifications of the brain connectivity at rest explored by rsfMRI, DTI, and DSI.

Abstract:

Introduction:

We have previously shown beneficial effects of manipulating the renin-angiotensin system (RAS) to improve functional outcome following spinal cord injury in rats. Furthermore, corresponding analyses of changes in gene expression at the injury site suggest that drug treatment altered several chemokines associated with infiltration of inflammatory cells. Compounds such as captopril, an angiotensin-converting enzyme (ACE) inhibitor, and losartan, an angiotensin II type 1 receptor (AT1R) blocker, have been associated with beneficial regulatory control of the neuroinflammatory response in models of CNS disorders (e.g., Alzheimer disease).

Within the injured spinal cord, macrophages express distinct functional phenotypes. M1 phenotypes exhibit tissue destructive properties while M2 phenotypes promote tissue repair. Although our previous work showed that treatment with captopril or losartan did not affect the overall macrophage response to injury at the injury epicenter, it is possible that the functional profile of the macrophages was altered by drug treatment. The aim of the present study was to extend these initial data and determine whether losartan treatment promoted deviation toward an M2 phenotype in macrophages either at the site of injury or rostral and caudal to the injury site. We used immunohistochemical techniques to analyze histopathological changes in response to spinal cord injury in rats treated with losartan and examined the functional phenotype of macrophages entering the spinal cord after compression injury. Tissues were stained with an antibody that specifically binds to mannose receptor, type C, a scavenger receptor associated with a reparative M2 macrophage phenotype. Rostral and caudal to the site of injury (lesion margins) we observed a decrease in the M2 response over time from 7 days post-injury to 28 days post-injury with an associated increase in the M1 response. These data suggest that the beneficial effects of RAS inhibition following SCI are not due to promotion of an intraspinal M2 phenotype.

Hypothesis: We hypothesized that inhibition of RAS via administration of an angiotensin receptor blocker (ARB) would alter the phenotype of recruited macrophages and other immune cells in spinal-injured rats.

Methods:

Anesthetized female Sprague-Dawley rats underwent a laminectomy at vertebral level T8 and were given SCI by lateral compression with modified forceps. Animals were treated daily with losartan (i.p.) and sacrificed at 7, 14, and 28 days post-injury.
Immunohistochemistry

Spinal cords were excised at the above mentioned days and stored at -80°C in a OCT compound before being cut on a cryostat at 10 mm intervals. 0.1 M phosphate buffer was used as our primary buffer solution, and biotinylated horse anti- mouse (BHAM) was used as a secondary antibody. Myelin was evaluated using Eriochrome Cyanine histochemistry and sections were stained macrophage and T-cells using the following specific antibody clones:

GFAP: astrocyte intermediate filament protein
OX-42: recognizes most macrophages via the integrin alpha M antigen which participates in various adhesive interactions of monocytes, macrophages, and granulocytes.
CD-206: mannose receptor type C present on both dendritic cells and macrophages. Selectively expressed on M2 macrophages and associated with initiation of tissue repair

Immunohistochemistry for proportional area of stained tissue was measured using NIH ImageJ software. Images were imported into ImageJ and converted to 8-bit grayscale. The cross-section of the spinal cord was outlined and a thresholding tool was used to highlight the positively stained tissue. To determine the proportional area, the area of positively stained tissue was measured and divided by the total cross-sectional area of the spinal cord. The epicenter section was defined by the tissue section exhibiting the least amount of spared myelin. Sections were analyzed at 2 mm increments up to 6 mm rostral and 6 mm caudal to the epicenter for each animal. Glial cells were assessed using three antibodies that recognize different antigens: GFAP, OX42 and CD206.

Results:

GFAP: There was a significant effect of distance from the epicenter at 7 and 14 dpi, suggesting that the magnitude of GFAP expression differs across the rostrocaudal extent of the lesion. There was a significant effect of treatment with losartan observed at 28 dpi. Treatment with losartan decreased the magnitude of GFAP staining rostral and caudal to the epicenter, suggesting that inhibition of AT1R altered lesion dynamics and the induction of the astroglial scar.

OX-42: There was a significant effect of distance from the epicenter at 7, 14, and 28 dpi, suggesting that the macrophage response decreases as the distance from the epicenter increases. The overall macrophage response to injury was not affected by treatment with losartan, suggesting that beneficial effects on locomotor recovery were not due to changes in the magnitude of the inflammatory response to injury.

CD206: The relative expression of CD206 was similar at all rostrocaudal lesion locations at 7 and 28 dpi. Given that the overall magnitude of the macrophage response diminished at sites distal to the lesion epicenter, but expression of CD206 was maintained suggests that macrophages further from the injury epicenter are more likely to express an M2, or reparative phenotype. There was no effect of losartan on the proportion of M2 macrophages at any time point assessed.

Conclusion:

These findings suggest an effect of losartan on the astroglial scar, but not on the macrophage response to injury. Thus, it is possible that the beneficial effects observed on locomotor recovery in this model, and neuroprotective effects described in other models of CNS injuries, are not due to modulation of neuroinflammation, but instead may be due to effects on endogenous glial cells.

Title: The analysis of exercises stabilise the trunk for the co-ordinated movement of the upper limb
Speaker
Biography:

Abstract:

The motoral co-ordination is the notion which evolves together with the growth of knowledge and developing the science in this subject.
The aim of the work was the analysis of the movement of the upper limb in relation to the patients stable and unstable trunk after the stroke of the brain and also the valuation of practices havings on the aim of the stabiliti of the trunk.
32 patients spending on the department of neurological rehabilitation with the the recognition of the stroke at which any functional deficit stepped out in the upper limb took the part in the investigation. It was 16 women and 16 men in the group. The meaning of trunk for the co-ordination of the upper limb was estimated on the device ArmeoControl using of three games estimating: „Hunting perpendicular”; „Hunting horizontal”; „Time of the reaction” and two the authors' tests: „ wall” and „abacus”.
It was observed essential (p=0,015) the difference of results in the game estimating ”the time of the reaction” executed before practices, engaging work on the stable trunk and after the period 10 days of the therapy. Essential steps out statisticly the difference of results between first and second investigation executed in the supervisory group for the author's test „abacus”, for the game „hunting perpendicular” the and „time of the reaction”, before and after 10 the days of standard neurological physiotherapy in the supervisory group. It was observed also statisticly essential (p=0,040) the difference of results between groups in the game „hunting perpendicular”.
Both physiotherapy with the practices of the stability of the trunk and standard physiotherapy improves the prehensile efficiency of the hand. Physiotherapy steered on the strengthener of the trunk has the influence on enlargement of the co-ordination of the upper limb in the range of movements executed in the front plane. The improvement of the co-ordination of the upper limb is the effect of standard neurological physiotherapy in the range of movements executed in the arrow and front plane.
Key words: motive co-ordination, stable trunk, practices stabilise of the trunk

Abstract:

Close head injuries have been recognized as an important public health and issues that in the past was ignored or minimized in some settings. In the United States combat veterans returning to the community often were unable to function effectively due to a spectrum of residue effects including frank neuropsychological impairment, attentional problems, irritability, and a host of executive function issues. More recently such issues have gotten publicity in the National Football League where veterans of the game retire with a host of neuropsychological consequences. Public awareness campaigns have led to various programs for screening and recognizing these individuals. Moreover various interventions have been introduced including the use of potential cognitive enhancing agents, educational and employment accommodation, peer support programs. A history of head injury is often found in individuals in the correctional system. Part of the problem may be related to the socioeconomic status of individuals in the system, but it may related to why people are incarcerated in the first place. Those with known mental disorders are overrepresented in the correctional system. It should not be a surprise that individuals with neuropsychological impairments would be over represented.  We will present cases showing how unrecognized impairment may lead to more frequent incarcerations and failure to abide by rules of parole. We will discuss potential cognitive enhancing agents that may be effective and the use of odorants and nasal stimulation to improve function.

Abstract:

There is increasing evidences that favor the prenatal beginning of schizophrenia. These evidences point toward intra-uterine environmental factors that act specifically during the second pregnancy trimester producing a direct damage of the brain of the fetus [1]. The current available technology doesn't allow observing what is happening at cellular level since the human brain is not exposed  to a direct analysis in that stage of the life in subjects at high risk of developing schizophrenia. Methods. In 1977 we began a direct electron microscopic research of the brain of fetuses at high risk from schizophrenic mothers in order to finding differences at cellular level in relation to controls. Results. In these studies we have observed within the nuclei of neurons the presence of complete and incomplete viral particles that reacted in positive form with antibodies to herpes simplex hominis type I [HSV1] virus, and mitochondria alterations [2]. Conclusion. The importance of these findings can have practical applications in the prevention of the illness keeping in mind its direct relation to the aetiology and physiopathology of schizophrenia. A study of the gametes or the amniotic fluid cells in women at risk of having a schizophrenic offspring is considered. Of being observed the same alterations that those observed previously in the cells of the brain of the studied foetuses, it would intend to these women in risk of having a schizophrenia descendant, previous information of the results, the voluntary medical interruption of the pregnancy or an early anti HSV1 viral treatment as preventive measure of the later development of the illness.

Abstract:

Statement of the Problem: There is a lack of awareness about what happy hormones are, how to use positive words to feel energetic and what can be done to get happy hormones. People tend to feel unhappy for multiple reasons and neuropathic pain adds on Stress levels of not only the patient but the caregivers as well. Being in pain leads to feeling depressed and anxious in some cases.

Methodology & Theoretical Orientation: 

Review of Books and Research shows that getting a dosage of happy hormones will not only ease slight pain of the patient but feeling happy will also have a positive impact on the recovery of the patient. Adopting Laughter therapy and getting hormones which makes one feel good will help many to recover from Neuropathic pain /Long term sadness caused by having grief, Anger or Resentment, Depression & Anxiety.

Findings: One needs to work on his/her energies using Laughter Therapy which is a positive approach for not having Depression & Anxiety caused by Neuropathic pain. The therapy can be used as a Holistic way to recovery. 

Conclusion & Significance: The Laughter therapy which includes ways to get the dosage of happy hormones promotes overcoming Depression & Anxiety caused by Neuropathic pain, is a fun way to manage pain.  Repeated sessions to be conducted to remind patients that life while having pain or during the recovery should go beyond just seeking medical and counselling help and also include rebuilding Spiritual, Physical, Emotional, Relational and Mental health. The model has been put together from for testing in many settings including hospitals, elderly homes and senior citizen centres.  This is not a research book or paper. It is just an effort to demystify the help available for Depression & Anxiety caused by pain. It is an attempt to motivate and encourage people to seek help and take a simple approach to remember and work on all aspects of their recovery.

Abstract:

The present study aimed to elucidate the abnormalities in the development of rat brains and behaviours after drinking desalinated seawater prenatally. Three types of drinking water were employed as an experimental probe (bottled water, filtered desalinated seawater and tap desalinated seawater) to investigate neurobehavioral and morphological changes in the development of pup rats. Female rats from each group were administered water from their birth until gestation and lactation. The 1st and 2nd generation pups were divided into three groups: Group C, mothers and pups administered with bottled drinking water (the control group); Group F, mothers and pups administered with filtered drinking water; Group T, mothers and pups administered with unfiltered desalinated seawater (tap water). Morphological changes (CNS aberration) and neurobehavioral changes were studied. The aberrations recorded in the brain regions (cerebellum, cerebrum, medulla oblongata) and spinal cord of rat’s newborns from groups T and F may be due to oxidative stress in these tissues such as reduced glutathione, lipid peroxidation, peroxidase and super oxide dismutase. In conclusion, drinking desalinated seawater for a long time may cause teratogenic effects in the development of New-born rats.

Title: The meaning of local stability for the co-ordinated movement human palm
Speaker
Biography:

Abstract:

Introduction The motoral co-ordination is ability to executing folded movements: exactly, quickly and in changing conditions. The stability of the part of the human body is the essential element for the possibility of the realization of the movement. It is the special fix point for that part of the human body during the executed movement in space.
The aim of the work is the analysis of dependence between the chosen parameters of the motoral co-ordination wrist and human palm and the local stability or its lack.
The material and methods: 81 persons study (healthy, the stroke of the brain). Age of studied: 20-80 years old, the women and men. To the investigation of the parameters of the co-ordination movement (the range of movement, speed/ frequency of the movement, the strength of the flex of the palm) were used Hand Tutor device and hand dynamometer. The patients were examined in two exit positions: sitting without the support and lying with the stability of the trunk and the tested upper limb.
Results: The introduction of local stability influenced on the change of the parameters of the motoral co-ordination of the palm fingers and wrist.
The conclusions: Local stability influences on the improvement of the co-ordination movements in the radio - carpal joint and the human palm. Local stability applied during exercises with the patient selectively improves the co-ordination movement the practiced parts of the body.
Key words: stability, motoral co-ordination, the range of the movement, speed/frequency, grip hand.

Abstract:

Symptomatic Neonatal Arterial Ischemic Stroke (NAIS) refers to a perinatal ischemic stroke (revealed by brain imaging) with clinical signs; mainly focal seizures. NAIS is surprisingly common, affecting near 1 in 4,000 neonates at birth and produces a significant morbidity and long-term neurologic deficits.

Methods. We performed a multicenter observational prospective study in which 66 neonates more than 35 weeks of gestational age and NAIS were included between 2006-2016.  The objectives of this study were: 1) to investigate the pathogenic factors of NAIS (particularly prothrombotic factors), 2) to generate a distribution map based on early MRI data, 3) to analyze the relationship between CSF-NSE levels and brain lesions in neuroimaging (topology and volume), as well as the correlation between both biomarkers with the outcome at two years of age.

To examine the role of family history, maternal diseases and thrombophilia, 129 controls were recruited prospectively. The correlation between cortico-subcortical lesions and outcomes in motor, cognitive function and language function and epilepsy was performed by means of voxel-based lesion-symptom mapping technique.

Results. Thrombophilia, maternal diseases and thromboembolic events in the families did not differ between cases and controls.

The region posterior to the central sulcus was the most frequently affected in NAIS (71%) and this explains the reason that functional alterations related to language were the most prevalent outcome (40%).

CSF-NSE appears to be an early biomarker after an NAIS due to there was a relation between size, arterial territory of the infarct, and neurodevelopment at two years of age. Outcome at two years correlated well with infarct volume and topology. While descending corticospinal tracts diffusion-weighted MRI signal is predictive of motor outcome, cognitive function was mainly correlated with Stroke volume, being the most important cognitive predictor the stroke involving main branch MCA

Speaker
Biography:

Professor G. Dyachkova has 45 years of experience in traumatology and orthopedics, radiology. With her participation, 15 new diagnostic methods based on multislice and magnetic resonance tomography were developed, comprehensive studies were carried out to study the quality of bone in patients with diseases of the musculoskeletal system, which made it possible to increase the effectiveness of radiology diagnostics in justifying Ilizarov treatment methods for patients with injuries and bone diseases, improve the quality of life of patients. Professor Dyachkova published more than 350 papers on various aspects of radiology, the organization of health care, and received 18 patents for new methods of treatment and diagnostics.

Abstract:

Statement of the Problem: Congenital pseudoarthrosis of the tibia (CPT) remains one of the most complicated and rare condition, and this pathology still remains the subject of focus for many specialists, because complicated long and multi-stage surgical treatment and poor outcomes in 20-50% of cases. To study changes of bone and soft tissues in patients with congenital pseudoarthrosis by MSCT and MRI.

 Methodology & Theoretical Orientation:: The work is based on the study of results of treatment and examination of 25 patients with CPT, among them 11 were females, 14–males. In 93% of patients CPT was located in the lower third of the tibia. In most of the cases, etiology of CPT was associated with neurofibromatosis type 1 (46%), in 23%-fibrous dysplasia and in 31%-was idiopathic. We studied condition of bone and soft tissues at the site of congenital pseudoarthrosis of the tibia before commencing treatment, using radiographic methods- multi slice computed tomography (MSCT), magnetic resonance imaging (MRI) in order to make prognosis of treatment outcome and recurrence of the disease.

Findings: 25 patients with congenital pseudoarthrosis of the tibia (CPT) in the age group 8 to 40 years were examined by above mentioned radiographic methods, multi slice computed tomography (MSCT), magnetic resonance imaging (MRI) before treatment and after recurrence. The peculiarities and changes in structure of tibial and fibular cortex, periosteum and muscles at the site of pseudoarthrosis. We derived at complex findings and changes that cause recurrence, of pseudarthrosis after deformity correction, or treatment. We developed criteria for evaluation of bone quality in patients with CPT.

Conclusion & Significance: Structural changes in the soft tissue and the bone at the site of CPT, detected by MRI and MSCT, allow for rather precise interpretation of condition of bone, periosteum, muscles during various stages of treatment and this information can be used to choose appropriate technique and methods of treatment.

Title: Cell lineage reprogramming of astroglia into region-specific induced neurons
Speaker
Biography:

Areas of interest: Desenvolvimento do córtex cerebral, neurogênese adulta e terapias celulares

 

Abstract:

Astroglial cells are abundant in the injured central nervous system and have been proposed as an endogenous source of cells for neuronal repair. Notably, genetic manipulation of these cells using exogenous genes, micro RNAs or small molecules has been shown to induce their phenotypic conversion into induced neuronal cells (iN), capable of integrating into the brain circuitry following in situ transplantation. Recent work in my laboratory has contributed to unravel the potential of astroglial cells isolated from distinct central nervous system structures. Using astroglial cells isolated from the neocortex, cerebellum and retina, we could show the widespread potential of these cells to be lineage reprogrammed into iNs. Importantly, we show that astroglia isolated from different regions differentiate into iNs with phenotypes resembling that of endogenous neurons, suggesting that region-specific astroglia are prompted to regenerate neurons of the same region. However, integration of astroglia-derived iNs in the adult mouse brain is limited as compared to the post-natal brain, indicating that further improvements are required towards the development of astroglia-based therapies.
