(FIG. 5) Z o o b a n k r e g i s t r a t i o n: u r n: l s i d: z o o b a n k. org:act: A6005873-8045-40E2-B0E1-DE073A2EC66B. Specific diagnosis: Test diameter 139.20–153.80 µm, average of 146.78 µm (N = 21); aperture 48.70– 59.10 µm, average 53.76 µm (N = 21). Colour ranges from transparent to yellow-orange. The test has a discoid, flattened shape. The edges of the test are somehow curved, giving the whole test a concave outlook, like a bowl. The aboral side of the test is flat. Building units can be partially covered with a proteinaceous matrix preventing the observation of these units. When this proteinaceous matrix is absent, small pores can be observed at the vertices of the building units, which are then located on both the aboral and oral sides. The oral side presents an aperture invaginated outwards forming a short ring or lip surrounded by many small pores. Intraspecific variability: The number of pores at the base of the test and the degree of coverage by the organic matrix can be variable. There may be certain deformations in the test that prevent it from having a perfectly circular morphology. Differences: Galeripora naiadis can be diagnosed by its specific sequences of the mtDNA markers and by its phylogenetic placement. Differs morphologically from other species closely related to Galeripora polypora by presenting (1) morphometric differences (see Morphometrics and morphology; Fig. 2) and (2) by its concave outlook. Habitat: Submerged vegetation, Ceratophyllum submersum, in an artificial lake. Type locality: Bulgaria: Sofia, Sofia Southern Park (42°39’N 23°18’E). Etymology: The name is derived from the Greek Ναϊάδες, the Naiads, who were female spirits or nymphs who ruled the rivers in Ancient Greek mythology. We propose this name to refer to the ecology of this species – pristine freshwater environments.Published as part of González-Miguéns, Rubén, Soler-Zamora, Carmen, Villar-Depablo, Mar, Todorov, Milcho & Lara, Enrique, 2022, Multiple convergences in the evolutionary history of the testate amoeba family Arcellidae (Amoebozoa: Arcellinida: Sphaerothecina): when the ecology rules the morphology, pp. 1044-1071 in Zoological Journal of the Linnean Society 194 (4) on pages 1064-1065, DOI: 10.1093/zoolinnean/zlab074, http://zenodo.org/record/646126

Specific diagnosis: Test diameter: 71.65–74.95 µm, average 73.20 µm (N = 4); aperture 11.15 to 12.10 µm average 11.50 µm (N = 4). Colour ranges from transparent to yellow-orange. General test shape is rounded and flattened. The aboral side of the test has a small elevation at the top that gives the test a helmet shape; the surface does not have pores and presents a granular pattern of irregular shape. Large ridges cross the aboral side of the test. The oral side of the test is smooth, covered with an organic matrix that prevents the observation of test building units, with a central aperture. Pores are localized on the brim of the oral side and around the aperture, following a circular pattern. The aperture is invaginated outwards forming a short ring or lip. Intraspecific variability: The shape and number of ridges on the aboral side of the test can be variable. The number of pores around the aperture is variable. There may be certain deformations in the test that prevent it from having a perfectly circular morphology. Diagnosis with closely related species: Galeripora galeriformis can be diagnosed by its specific sequences of the mtDNA markers and by its phylogenetic placement (see Molecular phylogeny; Fig. 1). Differs morphologically from other species closely related to Galeripora arenaria by presenting (1) morphometric differences (see Morphometrics and morphology; Fig. 2), with a smaller test and aperture diameters than all species presented here; (2) pores along the edge of the base test; (3) presence of a dome in the top part of the test; and (4) irregular granulations of the top surface of the test. Habitat: Moss on dry gypsum; terrestrial. Type locality: Spain, Madrid, Rivas-Vaciamadrid, near Laguna del Campillo (40°19’N 3°30’W). Etymology: The name is derived from the Latin galerus, helmet, and forma, shape. We propose this name because a Roman helmet is round and wide with a flat brim, similar to the test of this species.Published as part of González-Miguéns, Rubén, Soler-Zamora, Carmen, Villar-Depablo, Mar, Todorov, Milcho & Lara, Enrique, 2022, Multiple convergences in the evolutionary history of the testate amoeba family Arcellidae (Amoebozoa: Arcellinida: Sphaerothecina): when the ecology rules the morphology, pp. 1044-1071 in Zoological Journal of the Linnean Society 194 (4) on pages 1062-1063, DOI: 10.1093/zoolinnean/zlab074, http://zenodo.org/record/646126

Specific diagnosis: Test diameter: 86.50–92.65 µm, average 88.89 µm (N = 8); aperture 16.20–16.85 µm, average 16.60 µm (N = 3). Colour ranges from transparent to yellow-orange. General test shape is rounded and flattened. The aboral side of the test has several ridges that elevate the test forming a dome and flap borders; the surface does not have pores and presents a granular pattern of regular shape. The oral side of the test is smooth, covered with an organic matrix that prevents observation of the test building units, with a central aperture. Pores are localized only around the aperture, following a circular pattern. The aperture is invaginated outwards forming a short ring or lip. Intraspecific variability: The shape and number of ridges on the aboral side of the test can be variable. The number of pores around the aperture is variable. There may be certain deformations in the test that prevent it from having a perfectly circular morphology. Diagnosis with closely related species: Galeripora sitiens can be diagnosed by its specific sequences of the mtDNA markers and by its phylogenetic placement. Differs morphologically from Galeripora arenaria and closely related species by (1) morphometric differences (see Morphometrics and morphology; (Fig. 2); (2) the absence of pores along the edge of the aboral side of the test; and (3) a regular granulation of the top surface of the test. Habitat: Moss on dry slate and quartzite terrestrial. Type locality: Spain, Castilla La Mancha, Almonacid de Toledo (39°44’N 3°51’W). Etymology: The name is derived from the Latin sitiens, dry or thirsty. We propose this name because the habitat of this species is characterized by prolonged drought with episodic rainfall.Published as part of González-Miguéns, Rubén, Soler-Zamora, Carmen, Villar-Depablo, Mar, Todorov, Milcho & Lara, Enrique, 2022, Multiple convergences in the evolutionary history of the testate amoeba family Arcellidae (Amoebozoa: Arcellinida: Sphaerothecina): when the ecology rules the morphology, pp. 1044-1071 in Zoological Journal of the Linnean Society 194 (4) on pages 1063-1064, DOI: 10.1093/zoolinnean/zlab074, http://zenodo.org/record/646126

Specific diagnosis: Test diameter 180.06–200.14 µm, average of 187.77 µm (N = 19); aperture 24.37– 33.35 µm, average 29.56 µm (N = 10). Colour ranges from transparent to yellow-orange. Subhemispherical test shape, with flattened edges and dimples in the surface that gives the test a golf-ball shape. The aboral side presents no ribs or keels. Building units are covered with an organic matrix that prevents observation of the building units, giving a smooth outlook to the test. The oral side is also flat and smooth, covered with an organic matrix that prevents observation of the test building units, with a central aperture. The only pores at the base of the test are localized around the aperture, following a circular pattern and curling slightly outwards to form a small ring or lip. Intraspecific variability: The number of pores surrounding the aperture can be variable. There may be certain deformations in the test that prevent it from having a perfectly circular morphology. Diagnosis with closely related species: Galeripora succelli can be diagnosed by its specific sequences of the mtDNA markers and by its phylogenetic placement. Galeripora succelli differs from Arcella guadarramensis by (1) its morphometric differences (see Morphometrics and morphology; Fig. 2) and it is larger than A. guadarramensis (see above); (2) a regular and marked granulation on the top of the test; and (3) the absence of pores along the edge of the arboral side of the test. Habitat: Wet Sphagnum moss, in a bog. Type locality: France, Frasne, La Tourbière (46°49’N 6°9’E). Etymology: The name is derived from the Gaulish god Succellos (-or Succellus, in its latinized form). ‘ Cellos ’ meaning striker and the prefix ‘ su ’ good, the god’s name could, therefore, be translated as ‘the Good Striker’. As god of agriculture, forests and traditional medicine, he was believed to be in charge of keeping the soil fertile. We propose this name in referring to the type locality being a fertile place with a great abundance of vegetation and surrounded by many crops.Published as part of González-Miguéns, Rubén, Soler-Zamora, Carmen, Villar-Depablo, Mar, Todorov, Milcho & Lara, Enrique, 2022, Multiple convergences in the evolutionary history of the testate amoeba family Arcellidae (Amoebozoa: Arcellinida: Sphaerothecina): when the ecology rules the morphology, pp. 1044-1071 in Zoological Journal of the Linnean Society 194 (4) on page 1062, DOI: 10.1093/zoolinnean/zlab074, http://zenodo.org/record/646126

Holotype: MA-Algae11251. Specific diagnosis: Test diameter: clade L: 114.60– 125.90 µm, average 120.30 µm (N = 6); aperture 19.60– 30.00 µm, average 23.63 µm. clade M 141.50–149.95 µm, average 146.06 µm (N = 4); aperture 31.25–34.50 µm, average 33.08 µm. Besides a difference in size, both clades have an identical morphology. Colour ranges from transparent to yellow-orange. Subhemispherical test shape, with flattened edges and dimples in the surface that gives the test a golf ball shape. No ribs or keels on the aboral side. Hexagonal building units are visible, which gives the test a rough appearance; little pores can be seen at the vertices. Building units can also be appreciated at the oral side of the test, with pores at the vertices and a central aperture. The aperture is invaginated outwards forming a short ring or lip. Intraspecific variability: The building units may vary slightly in shape. Some building units may be collapsed, giving a rough surface. There may be certain deformations in the test that prevent it from having a perfectly circular morphology. Diagnosis with closely related species: Arcella guadarramensis can be diagnosed by its specific sequences of the mtDNA markers and by its phylogenetic placement. Arcella guadarramensis differs morphologically from similar-looking G. succelli by (1) its morphometric differences with G. succelli (see Morphometrics and morphology; Fig. 2), both, clade N and O, are notably smaller than G. succelli and (2) the rough outlook of the test. Habitat: Wet Sphagnum moss, in a fen. Type locality: Spain, Madrid, Puerto de Canencia (40°52’N 3°45’W). Etymology: The name is derived from River Guadarrama, a river with a name of Arabic roots: wadi, river, and ar-rama, sandy. We propose this name as a reference to the type locality in ‘Sierra de Guadarrama’, a mountain range named after this river. We provide a key (Supporting Information, Table S3) and a new figure (Supporting Information, Fig. S3) to facilitate the identification of the new species.Published as part of González-Miguéns, Rubén, Soler-Zamora, Carmen, Villar-Depablo, Mar, Todorov, Milcho & Lara, Enrique, 2022, Multiple convergences in the evolutionary history of the testate amoeba family Arcellidae (Amoebozoa: Arcellinida: Sphaerothecina): when the ecology rules the morphology, pp. 1044-1071 in Zoological Journal of the Linnean Society 194 (4) on pages 1065-1066, DOI: 10.1093/zoolinnean/zlab074, http://zenodo.org/record/646126

Allergic Rhinitis in Children
Get PDFThe author points out the special features of the allergic rhinitis in childhood in regards to the epidemiology, the clinics, the diagnosis and the treatment. The high frequency of the disease from early childhood, affects the development of the child and it could lead to different complications, first of which is the bronchial asthma. The diagnosis in children is much harder in comparison to the one in adults. The main principle while curing the disease is for the process to be conservative. A scheme is given for the therapeutic behavior within the different forms of allergic rhinitis in children.--------------------------------------Авторът посочва особеностите на алергичните ринити в детската възраст по отношение на епидемиологията, клиниката, диагнозата и лечението. Изтъква се голямата честота на това заболяване още от ранна детска възраст, което се отразява върху цялостното развитие на детето и може да доведе до различни усложнения, на първо място бронхиална астма. Диагнозата при децата е много по-трудна в сравнение с възрастните, а главният принцип при лечението е последното да бъде щадящо. Дадена е схема за терапевтично поведение при различните форми на алергичен ринит при децата

Lantana viburnoides sp viburnoides var kisi is used in Tanzania ethnobotanically to repel mosquitoes as well as in traditional medicine for stomach ache relief. Bioassay-guided fractionation and subtraction bioassays of the dichloromethane extract of the root barks were carried out in order to identify the bioactive components for controlling Anopheles gambiae s.s. mosquito larvae. Twenty late III or early IV instar larvae of An. gambiae s.s. were exposed to various concentrations of the plant extracts, fractions, blends and pure compounds, and were assayed in the laboratory by using the protocol of WHO 1996. Mean mortalities were compared using Dunnett's test (p < 0.05) and lethal concentration calculated by Lackfit Inversel of the SAS programme. The crude extract (LC50 = 7.70 ppm in 72 h) and fractions exhibited different level of mosquito larvicidal activity with subtraction of some fractions resulting in activity enhancement. The active fractions contained furanonaphthaquinones regio-isomers (LC50 = 5.48-5.70 ppm in 72 h) and the lantadene triterpenoid camaric acid (LC50 = 6.19 ppm in 72 h) as active principles while the lupane triterpenoid betulinic acid (LC50 < 10 ppm in 72 h) was obtained from the least active fraction. Crude extracts and some fractions had higher or comparable larvicidal activity to the pure compounds. These results demonstrate that L. viburnoides sp viburnoides var kisi extracts may serve as larvicides for managing various mosquito habitats even in their semi-purified form. The isolated compounds can be used as distinct markers in the active extracts or plant materials belonging to the genus Lantana
COI Barcoding of Nebelid Testate Amoebae (Amoebozoa: Arcellinida): Extensive Cryptic Diversity and Redefinition of the Hyalospheniidae Schultze
No full textWe used Cytochrome Oxidase Subunit 1 (COI) to assess the phylogenetic relationships and taxonomy of Nebela sensu stricto and similar taxa (Nebela group, Arcellinida) in order to clarify the taxonomic validity of morphological characters. The COI data not only successfully separated all studied morphospecies but also revealed the existence of several potential cryptic species. The taxonomic implications of the results are: (1) Genus Nebela is paraphyletic and will need to be split into at least two monophyletic assemblages when taxon sampling is further expanded. (2) Genus Quadrulella, one of the few arcellinid genera building its shell from self-secreted siliceous elements, and the mixotrophic Hyalosphenia papilio branch within the Nebela group in agreement with the general morphology of their shell and the presence of an organic rim around the aperture (synapomorphy for Hyalospheniidae). We thus synonymise Hyalospheniidae and Nebelidae. Hyalospheniidae takes precedence and now includes Hyalosphenia, Quadrulella (previously in the Lesquereusiidae) and all Nebelidae with the exception of Argynnia and Physochila. Leptochlamys is Arcellinida incertae sedis. We describe a new genus Padaungiella Lara et Todorov and a new species Nebela meisterfeldi n. sp. Heger et Mitchell and revise the taxonomic position (and rank) of several taxa. These results show that the traditional morphology-based taxonomy underestimates the diversity within the Nebela group, and that phylogenetic relationships are best inferred from shell shape rather than from the material used to build the shell.
