Review of "The Blood-Cerebrospinal Fluid Barrier" by Wei Zheng and Adam Chodobski (editors)

This multi-author volume on the blood-cerebrospinal fluid barrier summarizes past and current research in the areas of choroid plexus and cerebrospinal fluid in health and disease

Physical principles of membrane organization

Membranes are the most common cellular structures in both plants and animals. They are now recognized as being involved in almost all aspects of cellular activity ranging from motility and food entrapment in simple unicellular organisms, to energy transduction, immunorecognition, nerve conduction and biosynthesis in plants and higher organisms. This functional diversity is reflected in the wide variety of lipids and particularly of proteins that compose different membranes. An understanding of the physical principles that govern the molecular organization of membranes is essential for an understanding of their physiological roles since structure and function are much more interdependent in membranes than in, say, simple chemical reactions in solution. We must recognize, however, that the word &lsquo;understanding&rsquo; means different things in different disciplines, and nowhere is this more apparent than in this multidisciplinary area where biology, chemistry and physics meet.<br /

Book of Hours/Ours: Cicely Cottingham I Victor Davson

The Book of Hours/Ours project emerged as a result of curator Cynthia Hawkins’ invitation to have concurrent exhibitions at the Bertha V.B. Lederer Gallery at SUNY Geneseo. It came to us during the height of the Covid-19 crisis in New Jersey when we were confined to our small American Bungalow on the side of the first ridge of the Watchung Mountains called First Mountain (20 minutes up the hill from downtown Newark). The bungalow is designed with windows all around that look out on the surrounding landscape. Because of the abrupt end to the activity of our busy lives, we often found ourselves in dialogue with one another while contemplating the beauty of the nature surrounding us. From conversations, we landed on the idea of a joint project rather than separate exhibitions. The title is a play on the Christian devotional book popular in the Middle Ages called A Book of Hours. Cicely had already embarked on a series of watercolors that were within a larger project called “Tomorrow will come on its green footsteps” (a line from a poem by Pablo Neruda) and she suggested we use the same format for our project. Victor, who does not consider himself a landscape painter nevertheless chose landscape as his subject. The works that comprise the project reference the structure of a printed book that is made up of a “signature” of sixteen pages. Eight works are by Cicely and eight works are by Victor.https://knightscholar.geneseo.edu/geneseo-authors/1011/thumbnail.jp

Riscos ambientais em comunidades subnormais - a comunidade Santa Clara no bairro do Castelo Branco

The rapid and disorderly way as has been occurring urbanization causes conurbations grow chaotically, with the absence of basic infrastructure, poor housing and poor services, further accentuating the environmental problems in urban areas, making the poor live with conditions of disaster risk in areas of geomorphological hazards, flood plains area among others. Given all the problems exposed, this study sought to identify some environmental risks that the population of the Community Subnormal Santa Clara, in the district of Castelo Branco II, the capital city of Joao Pessoa Paraiba, is inserted. Aiming thus contribute to the studies on urban management in community subnormal, with respect to issues related to threats, vulnerabilities and disaster risks. Were found at the study site several factors that may trigger a disaster, such as release of wastewater on the slopes, houses with structural hazards and anthropogenic changes in natural slopes, such as cutting and inappropriate cultivation of some plant species in unstable slopes. Were also seen major structural works undertaken by the municipal government, with respect to slope stabilization and storm water drainage, but all these made no minimal knowledge of the population about its features, generating some fears and misgivings.A forma acelerada e desordenada como vem se dando a urbanização faz com que os aglomerados urbanos cresçam de forma caótica, com ausência de infraestrutura básica, habitações precárias e serviços deficientes, acentuando ainda mais os problemas ambientais no meio urbano, fazendo com que a população carente conviva com condições de risco de desastres, em áreas de riscos geomorfológicos, área de várzeas de inundações entre outros. Tendo em vista toda a problemática exposta, este trabalho buscou identificar alguns riscos ambientais em que a população da Comunidade Subnormal Santa Clara, no bairro do Castelo Branco II, na cidade de João Pessoa capital Paraibana, encontra-se inserida. Objetivando-se assim contribuir para os estudos sobre gestão urbana em comunidade subnormais, no que tange às questões relacionadas às ameaças, vulnerabilidade e riscos de desastres. Foram encontrados no local de estudo vários fatores que podem vir a desencadear um desastre, como lançamento de águas servidas nas encostas, casas com riscos estruturais e modificações antrópicas nos taludes naturais, como corte e cultivo inadequado de algumas espécies vegetais em encostas instáveis. Foram observadas também grandes obras estruturantes realizadas pela prefeitura municipal, no que tange a estabilização de taludes e drenagem pluvial, porém todas estas realizadas sem nenhum conhecimento mínimo da população, sobre as suas funcionalidades, gerando alguns medos e receios
