Beautiful economic features of public landscaping in city beautiful
City beautiful was a movement of great reach and inspiration, which apparently, was initiated in Chicago in 1893 during the World’s Columbian Exposition. The movement’s premises were artistic, architectural, social, political and economic. Among the artistic and architectural aspects of the city beautiful movement, the provision of high quality public landscaping was of paramount importance. As for the economic rationale behind the movement, we encounter the thinking that a beautiful city should increase its residents’ enjoyment of the city’s attributes and hence attachment to the city, raise real estate values as well as expand city business, with larger sales of city goods and services to local and touristic customers. This paper examines the economic rationale behind the city beautiful movement. We consider a “regional” economy consisting of two adjacent cities, which are identical in many of its attributes, such as the sizes of their populations. We build a general equilibrium model for the agents (consumers and producers) in this economy and demonstrate that the economic rationale behind the city beautiful movement is sound. Each city’s wealth and welfare are proportional to its quality level and a city’s quality level is proportional to the city’s public landscaping quality
HUMAN HERPESVIRUS-6 - A SURVEY OF PRESENCE AND DISTRIBUTION OF GENOMIC SEQUENCES IN NORMAL BRAIN AND NEUROGLIAL TUMORS
In an attempt to study the frequency and distribution of human herpesvirus-6 (HHV-6) infection both in normal and neoplastic brain tissues in vivo, polymerase chain reaction was used to look for HHV-6 genomes: 1) in samples, obtained at necropsy, from different regions of the brain of immunocompetent adult subjects and of patients who died of AIDS; 2) in the surgical biopsies of a well-characterized series of primary brain tumors of neuroglial origin. HHV-6-specific sequences were identified in six of nine brain samples from immunocompetent subjects, and in four of seven brain samples from AIDS patients. Viral sequences were identified in the specimens derived either from the grey (frontal cortex and basal ganglia) or from the periventricular white matter. HHV-6 DNA was found only in 6 of the 37 primary brain tumor biopsies examined. Th is study provides for the first time molecular evidence of a wide distribution of HHV-6 infection in the brain tissues of a high proportion of subjects, both in normal and in impaired immunity. in this large series of tumor biopsies the presence of HHV-6 genomic sequences is a rare phenomenon, arguing against a major role of this herpesvirus in the pathogenesis of primary brain tumors of neuroglial origin in immuno-competent subjects
Teledermatology and Inflammatory Skin Conditions during COVID-19 Era: New Perspectives and Applications
Background: The most frequent inflammatory skin diseases are psoriasis, atopic dermatitis, hidradenitis suppurativa, and acne. Their management is challenging for dermatologists since their relapsing chronic clinical course is associated with a great impact on quality of life. Nevertheless, the recent introduction of novel therapies, such as biological drugs and small molecules has been changing the history of these diseases. Methods: A systematic review of the scientific literature of case reports, case series, epidemiological studies, reviews, and systematic reviews regarding teledermatology and inflammatory skin disease. Studies were identified, screened, and extracted for relevant data following the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Results: A total of 69 cases articles were included in the review. Conclusions: As we have shown in the review, several experiences of teledermatology for patients affected by inflammatory skin diseases have been demonstrated to increase due to clinical access to hospital and specialized health care services, allowing better access to specialized dermatology care for people living in remote areas, and saving costs and money with health care
Antineoplastic effects of liposomal short interfering RNA treatment targeting BLIMP1/PRDM1 in primary effusion lymphoma
RNA interference (RNAi) has been suggested to represent a promising therapeutic approach in different disease settings. Primary effusion lymphoma (PEL) is a plasmablastic lymphoma consistently expressing B lymphocyte-induced maturation protein 1 (Blimp-1), a pivotal transcriptional regulator during terminal differentiation of B cells into plasma cells. Here we report, for the first time, that transient knockdown of the BLIMP1 gene (also known as PR Domain Containing 1 with ZNF Domain, or PRDM1) using small interfering RNA (siRNA) delivered by liposomes, induced remarkable killing in PEL cell lines. Furthermore, in a murine model of PEL, significantly prolonged survival was achieved by intraperitoneal treatment with such anti-BLIMP1 lipoplexes, while no vector-induced toxicity was observed. This effective and safe RNAi strategy, based on liposomal siRNA targeting a master transcription factor of post-germinal center B cells, may indeed be a potential treatment against plasmablastic lymphom
