Severe Craniocerebral Trauma

This research points out how valuable the brain in humans is, it indicates from the definition of the word brain, of the nervous system, composition of the skull, parts of the brain, responsibilities of the brain, actions to keep the brain in good shape, the power that he has the brain and the senses that he indicates himself. There is a case study of an accident that caused a severe craniocerebral trauma teacher and the sequelae that will already be part of her teacher's daily life and the knowledge that these sequelae may continue to appear during the 3 years of the accident. It also presents the progress that has been achieved over 10 months of recovery, this with the aim of creating awareness in people and understanding how important the brain is to continue living in this magnificent world.

AbstractConditional mutagenesis and fate mapping have contributed considerably to our understanding of physiology and pathology. Specifically, Cre recombinase-based approaches allow the definition of cell type-specific contributions to disease development and inter-cellular communication circuits in respective animals models. Here we compared Cx3cr1CreER and Sall1CreER transgenic mice and their use to decipher the brain macrophage compartment as a showcase to discuss recent technological advances. Specifically, we highlight the need to define the accuracy of Cre recombinase expression, as well as strengths and pitfalls of these particular systems that should be taken into consideration when applying these models.

Considering that Mathematics is a multidimensional problem-solving method that can be effective in all areas of cultural life, it is of great importance because of its contribution to other sciences such as physical and social sciences. It is known that the basic concepts of mathematics, which can also be expressed as a way of life, have helped to increase the usefulness of mathematics to practical and even social sciences such as physics, chemistry, biology, economics, engineering and military, as well as their own values. In addition, if abstract subjects and concepts in mathematics are used in other sciences, concrete results can be obtained, which facilitate the labor of humans. In this case, it is useful to illustrate the mathematics of everyday life in order to understand the importance of mathematics. The word “function”, which is often used in everyday life as in mathematics, is one of the basic concepts in mathematics. Relating the learned knowledge and the acquired skills related to this concept to everyday life can affect the memory duration of learned knowledge and subsequent learning. Considering the importance of the subject, a case study has been conducted with (62) students. In the study, the definition of the function and two daily life examples related to the definition were presented to the candidates in black and white. The candidates were asked to make the definition of the types of functions presented to make sampling from daily life by making analogies. Content analysis was used in the analysis of the data. In the study, it was determined that the candidates could not go beyond the ordinary in writing samples. In addition, the success rates of candidates’ ability to define and write daily life examples have been quite different.

El panhipopituitarismo (PH) hace referencia a la pérdida total de la función de la hipófisis anterior (adenohipófisis) que incluye los ejes somatótropo, tirótropo, corticótropo, gonadótropo, entre otros. La diabetes insípida central (DIC) no está contemplada en la definición de PH y su asociación simultánea implica la destrucción o degeneración de las neuronas localizadas en los núcleos supraóptico y paraventricular a nivel hipotalámico, es decir, un compromiso más extenso, dicha asociación se ha reportado hasta en 27% de los casos de linfoma primario del sistema nervioso central (LPSNC), la presencia de esta alteración obliga siempre a descartar enfermedades de carácter hematológico, infiltrativo, infeccioso y autoinmune. Presentamos el caso de una paciente de 19 años quien debutó con PH y DIC en la que no se pudo esclarecer un diagnóstico definitivo en su abordaje inicial, luego de casi tres años de evolución, una segunda biopsia realizada a nivel cerebral permitió confirmar el diagnóstico de linfoma primario del SNC. El curso lento y progresivo observado en nuestra paciente es propio de dicha neoplasia; sin embargo, el efecto citorreductor de los corticoides utilizados para el manejo de su déficit hormonal, favoreció el retraso en la identificación de esta enfermedad hematológica.Abstract The panhypopituitarism (PH) refers to total loss of function of the anterior pituitary (adenohypophysis), which ultimately can lead to commitment at differents endocrine axes involved at this level. Central diabetes insipidus (CDI) is not covered by the definition of PH and its simultaneous association involves the destruction or degeneration of neurons located in the supraoptic and paraventricular nuclei of the hypothalamus, it means a greater and more extent commitment. We present the case of a 19 years old female who debuted with PH and CDI in which failed to elucidate a definitive diagnosis in its initial approach. Finally, after nearly three years of evolution and a second biopsy performed in the brain the diagnosis of primary central nervous system lymphoma was confirmed.

Intelligence is the ability to find solutions to complex problems a life faces in a complex and uncertain environment. This cannot be captured by a standardized numerical score, such as IQ, that focuses on a narrow range of cognitive capabilities, such as working memory or verbal fluency. Intelligence also cannot be separated from the most essential property of all life forms, which is self-replication. This chapter briefly reviews the evolutionary history and diversity of intelligence from single-cell organisms to humans. The chapter includes a definition of intelligence and a discussion of how the nervous system works, the simple behavior of reflexes and the limitations of reflexes, connectome (the comprehensive map of all the connections in an animal’s nervous system), the multiple controllers for muscles, and the social nature of many behaviors. The chapter also includes a case study on eye movements.

It is spent electroencephalographic (EEG) research, the computer analysis with definition of indexes of the basic rhythms, the vegetative status under the program of variability of a rhythm of heart is studied, functional classes (FC) on D.I. Zhemajtite are defined. At all patients changed types EEG prevailed. It is noted low FC at patients with I, II, V types ЭЭГ. Correlation of type EEG with level FC is revealed: at patients with V type EEG prevailed IV and V, with I and II types EEG — higher (II, III) FC. The high index of an alpha rhythm correlates with high II FC, and a beta rhythm with III FC. Decrease in adaptable mechanisms of vegetative regulation defines necessity of medicament correction.

Underage drug users show very large numbers, so understanding the dangers of drugs needs to be planted as early as possible. Supervision is not only done by parents at home, but also by teachers and the surrounding community. Through the method of telling children, it is expected to be able to distinguish good deeds and bad deeds so that they can be applied in daily life. The method of telling stories using illustrated storybooks that are packaged in an interesting way can be of particular concern to children. The adverse effects of drug use, for children not only will lose their future but will also lose their identity as young people who are creative and innovative, using drugs means children damage themselves, because as we all know that drug use will continually damage the nervous system the brain that will be felt throughout his life, even if the person has stopped using drugs. The method of telling stories by conveying information and knowledge to early childhood about the adverse effects of drug use is fun and will be stored in memory until adulthood so that the hopes and desires to make the younger generation will avoid drugs will be realized.

When the transmission electron microscope was commercially introduced a few years ago, it was heralded as one of the most significant aids to medical research of the century. It continues to occupy that niche; however, the scanning electron microscope is gaining rapidly in relative importance as it fills the gap between conventional optical microscopy and transmission electron microscopy.IBM Boulder is conducting three major programs in cooperation with the Colorado School of Medicine. These are the study of the mechanism of failure of the prosthetic heart valve, the study of the ultrastructure of lung tissue, and the definition of the function of the cilia of the ventricular ependyma of the brain.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Barnacles are very specialized Crustacea, with strongly reduced head and abdomen. Their nervous system is rather simple: the brain or supra-oesophageal ganglion (SG) is a small bilobed structure and the toracic ganglia are fused into a single ventral mass, the suboesophageal ganglion (VG). Neurosecretion was shown in barnacle nervous system by histochemical methods and numerous putative hormonal substances were extracted and tested. Recently six different types of dense-core granules were visualized in the median ocellar nerve of Balanus hameri and serotonin and FMRF-amide like substances were immunocytochemically detected in the nervous system of Balanus amphitrite. The aim of the present work is to localize and characterize at ultrastructural level, neurosecretory neuron cell bodies in the VG of Balanus amphitrite.Specimens of Balanus amphitrite were collected in the port of Genova. The central nervous system were Karnovsky fixed, osmium postfixed, ethanol dehydrated and Durcupan ACM embedded. Ultrathin sections were stained with uranyl acetate and lead citrate. Ultrastructural observations were made on a Philips M 202 and Zeiss 109 T electron microscopy.

Abstract Complex trauma resulting from chronic maltreatment and prenatal alcohol exposure can significantly affect child development and academic outcomes. Children with histories of maltreatment and those with prenatal alcohol exposure exhibit remarkably similar central nervous system impairments. In this article, I will review the effects of each on the brain and discuss clinical implications for these populations of children.
