Emtree terms added and changed (January 2021) This is an overview of new terms added and changes made in the first Emtree release in 2021. Overall, Emtree has grown by 1,617 preferred terms (457 drug terms and 1,198 non-drug terms) compared with the previous version released in September 2020. In total Emtree now counts 88,945 preferred terms. Because the terms added include replacements for existing preferred terms (which become synonyms of the new terms) as well as completely new concepts, the number of terms added exceeds the net growth in Emtree. Other changes could include the merging of two or more existing preferred terms into a single concept. The terms added and changed are summarized below and specified in detail on the following pages. Emtree terms added in January 2021 1,695 new terms (including 78 replacement terms and promoted synonyms) have been added to Emtree as preferred terms in version January 2021 (compared to September 2021): 457 drug terms (terms assigned to the Chemicals and Drugs facet). 1,238 non-drug terms (terms not assigned as Chemicals and Drugs). The new terms (including the replacement terms and the promoted synonyms) are listed as Terms added on the following pages. Note that many of these terms will have been indexed prior to 2021 (typically as candidate terms), sometimes for several years, before they were added to Emtree. Emtree terms changed in January 2021 87 terms (38 drug terms and 40 non-drug terms) from Emtree September 2020 have been replaced by 78 different terms in January 2021 (38 drug terms and 40 non-drug terms). Of these, 64 terms (28 drug terms and 36 non-drug terms) are new (e.g. new generic names for drug chemical names) and have been assigned creation date 2021; the remaining 14 replacement terms (10 drug terms and 4 non-drug terms) were already present in Emtree. 1 drug term was replaced by a non-drug term, no non-drug term was replaced by a drug term. No preferred terms were deleted. Changes are presented in alphabetical order of the new terms.

Labeling Mesenchymal Cells with DMSA-Coated Gold
Silva et al. J Nanobiotechnol (2016) 14:59 DOI 10.1186/s12951-016-0213-x Journal of Nanobiotechnology RESEARCH Open Access Labeling mesenchymal cells with DMSA‑coated gold and iron oxide nanoparticles: assessment of biocompatibility and potential applications Luisa H. A. Silva1, Jaqueline R. da Silva1, Guilherme A. Ferreira2, Renata C. Silva3, Emilia C. D. Lima2, Ricardo B. Azevedo1 and Daniela M. Oliveira1* Abstract Background: Nanoparticles’ unique features have been highly explored in cellular therapies. However, nanoparti- cles can be cytotoxic. The cytotoxicity can be overcome by coating the nanoparticles with an appropriated surface modification. Nanoparticle coating influences biocompatibility between nanoparticles and cells and may affect some cell properties. Here, we evaluated the biocompatibility of gold and maghemite nanoparticles functionalized with 2,3-dimercaptosuccinic acid (DMSA), Au-DMSA and γ-Fe2O3-DMSA respectively, with human mesenchymal stem cells. Also, we tested these nanoparticles as tracers for mesenchymal stem cells in vivo tracking by computed tomography and as agents for mesenchymal stem cells magnetic targeting. Results: Significant cell death was not observed in MTT, Trypan Blue and light microscopy analyses. However, ultra- structural alterations as swollen and degenerated mitochondria, high amounts of myelin figures and structures similar to apoptotic bodies were detected in some mesenchymal stem cells. Au-DMSA and γ-Fe2O3-DMSA labeling did not affect mesenchymal stem cells adipogenesis and osteogenesis differentiation, proliferation rates or lymphocyte suppression capability. The uptake measurements indicated that both inorganic nanoparticles were well uptaken by mesenchymal stem cells. However, Au-DMSA could not be detected in microtomograph after being incorporated by mesenchymal stem cells.

Abstract Engineered nanoparticles are defined as having a dimension that is between one and one hundred nanometres. With toxicology studies reporting various degrees of toxicity the need to investigate nanoparticle fate and behaviour is vital. Monodispersed engineered nanoparticles were synthesised in-house to produce suitable materials to examine such processes. Iron oxide nanoparticles (5 nm) and citrate coated silver nanoparticles (20 nm) were subjected to different conditions of pH, ionic strength and different types of commercially available natural organic matter. Changes in particle size and aggregation were examined using a multi-method approach. Results showed that the natural organic matter was able to adsorb onto nanoparticle surfaces and improve their stability when subjected to changes in pH and ionic strength, where they would normally aggregate.

Necrobiotic Xanthogranuloma Sucessfully Treated with Cyclosphospamide-Methyl Prednisolon Lesmono Bayu, Dewi Yussy Afriani, Ratunanda Sinta Sari, Aroeman Nur Akbar Departement of Otorhinolaryngology Head and Neck Surgery Faculty of Medicine Padjadjaran University-Dr. Hasan Sadikin General Hospital Bandung ABSTRACT Objective: Necrobiotic Xanthogranuloma (NXG) is a rare, chronic, and progressive disease that provokes skin lesions, such as damage of the histiocytes of Non-Langerhans cell, skin lesions (yellowish or noduled ulcerative lesions) in the induration skin. The most common predilection areas are on the face, orbital, and extremities. The etiology is still unknown, but sometimes is often associated with monoclonal gammopathy. The granulomatous infiltrate was composed of lymphocytes, epithelioid cells, foamy histiocytes and giant cells, many of them of Touton type. Some patients who had lesions are asymptomatic, sometimes they will feel paresthesias, burning pain. Nowadays, this management still vary widely, include medicamentous (cytostatics, steroids), radiotherapy, and surgery. Sets forth the results of two patients NXG. Methods: The subjects in this study were a 44-years-old male patient with some lesions on both cheeks and forehead since 5 months ago and a 29-years-old female patient with some lesions on both cheeks and ears. Results: First patient treated with Methylprednisolon 0.8 mg/Kg and tappered off for a month with improved results. Second patient treated with Cyclosphosphamide 750 mg/m2 with improved results within three weeks. Conclusion: Necrobiotic Xanthogranuloma treatment still required further research by the number of samples that much to find out the efficiency management NXG. Keywords: Cyclosphosphamide, methylprednisolon, necrobiotic xanthogranuloma 1 Introduction Necrobiotic Xanthogranuloma (NXG) is a rare disease, a chronic, progressive and cause skin lesions in the form of damage to the cell Non-Lagerhans histiocytes.

An Unusual Juvenile Xanthogranuloma on a Finger MCP Joint
200 An Unusual Juvenile Xanthogranuloma on a Finger MCP Joint Sang Hee Cha, M.D., Sang Hyun Cho, M.D., Jeong Deuk Lee, M.D. Department of Dermatology, College of Medicine, The Catholic University of Korea, Seoul, Korea Juvenile xanthogranuloma (JXG) is a benign self-limited histiocytic proliferative disorder that usually occurs in early childhood. JXG appears as reddish to yellow, papules, or nodules, and although the head, neck, and trunk are the most frequent locations, it can occur at any body site. However, JXG involving the finger is rare. Histologically, JXG is characterized by an ill-defined, unencapsulated, dense histiocytic infiltrate within the dermis, some of which is contained in Touton giant cells, foreign body giant cells and foamy cells. Because the cutaneous lesions spontaneously regress, treatment is not usually indicated. The authors report a case of JXG in a 4-year-old girl who had tender, yellowish papule on the ventral aspect of the MCP joint of the right fourth finger consistent with JXG.

Nongenetic Reactivation and Is Caused by the Action of the Uncoating Protein
Poxviruses Dr. Ali Hashemi Department of Microbiology, School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Introduction Structure and Composition Poxviruses are the largest and most complex of viruses infecting humans. Poxviruses are large enough to be seen as featureless particles by light microscopy. By electron microscopy, they appear to be brick-shaped or ellipsoid particles. An outer lipoprotein membrane,or envelope, encloses a core and two structures of unknown function called lateral bodies Cont…. The core contains the large viral genome of linear double- stranded DNA. The DNA contains inverted terminal repeats of variable length, and the strands are connected at the ends by terminal hairpin loops. The chemical composition of a poxvirus resembles that of a bacterium. Vaccinia virus is composed predominantly of protein (90%), lipid (5%), and DNA (3%). Classification Poxviruses are divided into two subfamilies based on whether they infect vertebrate or insect hosts. Most of the poxviruses that can cause disease in humans are contained in the genera Orthopoxvirus and Parapoxvirus; there are also several that are classified in the genera Yatapoxvirus and Molluscipoxvirus. Cont… Cont… The orthopoxviruses have a broad host range affecting several vertebrates. They include ectromelia (mousepox), camelpox, cowpox, monkeypox, vaccinia, and variola (smallpox) viruses. Some poxviruses have a restricted host range and infect only rabbits (fibroma and myxoma) or only birds. Others infect mainly sheep and goats (sheeppox, goatpox) or cattle (pseudocowpox, or milker’s nodule). Poxvirus replication Poxviruses are unique among DNA viruses in that the entire multiplication cycle takes place in the cytoplasm of infected cells. Poxviruses are further distinguished from all other animal viruses by the fact that the uncoating step requires a newly synthesized, virus-encoded protein.

NUMBER 1870 FEBRUARY 26, 1958 The Role of the "Third Eye" in Reptilian Behavior BY ROBERT C. STEBBINS1 AND RICHARD M. EAKIN2 INTRODUCTION The pineal gland remains an organ of uncertain function despite extensive research (see summaries of literature: Pflugfelder, 1957; Kitay and Altschule, 1954; and Engel and Bergmann, 1952). Its study by means of pinealectomy has been hampered in the higher vertebrates by its recessed location and association with large blood vessels which have made difficult its removal without brain injury or serious hemorrhage. Lack of purified, standardized extracts, improper or inadequate extrac- tion techniques (Quay, 1956b), and lack of suitable assay methods to test biological activity have hindered the physiological approach. It seems probable that the activity of the gland varies among different species (Engel and Bergmann, 1952), between individuals of the same species, and within the same individual. This may also have contrib- uted to the variable results obtained with pinealectomy, injection, and implantation experiments. The morphology of the pineal apparatus is discussed in detail by Tilney and Warren (1919) and Gladstone and Wakely (1940). Only a brief survey is presented here for orientation. In living vertebrates the pineal system in its most complete form may be regarded as consisting of a series of outgrowths situated above the third ventricle in the roof of the diencephalon. In sequence these outgrowths are the paraphysis, dorsal sac, parapineal, and pineal bodies. The paraphysis, the most I University of California Museum of Vertebrate Zoology.
