Phylogeny of Hyadinini (Diptera: Ephydridae) with an Emphasis on Structures of the Proboscis
2014
Abstract. The shape of adult mouthparts (proboscis) of all genera of Hyadinini (Diptera: Ephydridae) is provided, including variability of cibarium, lacinia and the number of pseudotracheae. Its usage in phylogenetic construction is documented. All ten genera are diagnosed, including the genus Lytogaster, which is formally restored from synonymy with Hyadina. The ventral receptacle of four genera (Garifuna, Parahyadina, Parydroptera and Pelinoides) and the male terminalia of Parahyadina are presented for the first time. Monophyly of the tribe is discussed and the relationships among genera of Hyadinini are proposed. Ten Hyadinini genera are grouped into four lineages 1) Pelina group with Pe…
The effectiveness of the information‐motivation model and domestic brushing with a hypochlorite‐based formula on peri‐implant mucositis: A randomized…
2021
OBJECTIVE Management of mucositis is essential for the long-term maintenance of dental implants. This study determined the efficacy, in terms of clinical parameters, of an adjunctive domiciliary agent paired with non-surgical periodontal therapy (NSPT) for patients with peri-implant mucositis. MATERIALS AND METHODS Patients involved in a periodontal maintenance program were randomly distributed to the domestic use of a chlorhexidine toothpaste and mouthwash (control) or a hypochlorite-based formula brushing solution (test) after diagnosis of peri-implant mucositis. A modified approach towards NSPTwas performed after 10 days of domestic use of the assigned maintenance product in both groups.…
The Centetostoma scabriculum complex—a group of three cryptic species (Arachnida: Opiliones: Nemastomatidae)
2011
Nemastoma scabriculum Simon, 1879 turned out to be a group of three closely related species of the Pyrenees in SW Europe (France and Spain). Though the species are similar in general habit they can easily be recognized by external morphology (structure of the apophysis of male chelicerae) and male genital morphology (penial structure). For Nemastoma scabriculum Simon, 1879 sensu stricto a lectotype is designated. The synonymous Nemastoma ventalloi Mello-Leitao, 1936 is considered to be a distinct species and is re-described. The third species of the group is described as new, Centetostoma juberthiei sp. n. Though partly sympatric in their restricted Pyrenean area, the individual species are…
Nikolai Shpanov and the Evolution of the Soviet Spy Thriller
2017
It is a common opinion that Stalinist literature knew no explicitly popular genres, and that, consequently, its whole body can be regarded as popular culture. The case of Nikolai Shpanov is one of the most evident arguments against such an interpretation. From the late Thirties to the early Fifties, Shpanov's works, centered around the fight with fiendish spies, had huge print runs and conspicuous success among the readers; yet, Soviet critics nearly ignored them. The publishing channels were not those of the officially endorsed "classics" of Socialist Realism, but rather what can be regarded as a Soviet equivalent of a separated mass publishing. Shpanov's books are, thus, the living proof …
L’identità della spia: classe e nazione nello spy-thriller sovietico
2019
I territori di confine annessi dall'Unione Sovietica negli anni di guerra costituivano un doppio problema per le autorità: l'eredità del sistema capitalista era ancora viva, e l'identità nazionale dei loro abitanti poco chiara. Questi territori, d'altro canto, erano l'ambientazione ideale per i romanzi di spionaggio, ed alcuni tra questi, come ad esempio Sul Tibisco (1954) di Aleksandr Avdeenko, che si svolge nell'Ucraina transcarpatica, una terra dall'appartenenza a lungo contestata, o L'apprendista stregone (1956) di Nikolaj Španov, ambientato in Lettonia, ottennero un buon successo. L'identità è la questione chiave nella narrativa di spionaggio; l'ossessione per l'identità, e per i doppi…
Effect of over-the-counter whitening strips and toothpaste on shear bond strength of orthodontic brackets
2021
Background To investigate: 1) the effects of over-the-counter white strip enamel bleaching and 2-Step whitening toothpaste application on the shear bond strength of orthodontic brackets at 24-hours and 7-days post-bleaching latent period; and 2) the correlation between amount of bleaching and shear bond strength. Material and Methods Sixty human premolar teeth were randomly assigned into two bleaching groups, white strip group treated with Crest® 3D WHITE™ LUXE Professional Effects Whitestrips (Proctor & Gamble, Greensboro, NC), and whitening toothpaste group, treated with Crest® 3D WHITE™ BRILLIANCE 2-Step Toothpaste (Proctor & Gamble, Greensboro, NC). The groups were further divided into …
Cephalic anatomy of Sinentomon erythranum Yin (Protura : Sinentomidae)
1992
Abstract The structure of the head capsule, endoskeletal structures, oral folds, mouthparts, foregut, maxillary and labial glands, and the central nervous system of the Chinese proturan Sinentomon erythranum Yin (Protura : Sinentomidae) have been described. The most significant features are the unusual thickness of the cuticle with numerous serrated lines, the reduction of sutures and the absence of linea ventralis, the simplification of gnathal pieces, and the reduction of the musculature. A comparison with other Protura and Apterygota leads to some morphological and phylogenetical interpretations of the cephalic structures, in particular those concerning the entotrophy.
Evaluation of a fluorosis prevention educational program: A randomized field trial.
2017
Background A 2-group randomized field trial was conducted to evaluate the impact of a fluorosis educational preventive program in mother´s knowledge and practices, and on the urine fluoride concentration of their preschool children. Material and Methods A group of 139 mother-child pairs participated in the study. Randomly, children were assigned to an intervention group, their mothers were participants of an educational program, or a control group (CG); including 69 and 70 child-mother pairs, respectively, the follow-up period was six months. Mother´s knowledge and practices were evaluated and children´s first urine sample was used to measure fluoride concentration at the beginning of the s…
A novel arousal-based individual screening reveals susceptibility and resilience to PTSD-like phenotypes in mice
2021
Translational animal models for studying post-traumatic stress disorder (PTSD) are valuable for elucidating the poorly understood neurobiology of this neuropsychiatric disorder. These models should encompass crucial features, including persistence of PTSD-like phenotypes triggered after exposure to a single traumatic event, trauma susceptibility/resilience and predictive validity. Here we propose a novel arousal-based individual screening (AIS) model that recapitulates all these features. The AIS model was designed by coupling the traumatization (24 h restraint) of C57BL/6 J mice with a novel individual screening. This screening consists of z-normalization of post-trauma changes in startle …
Bifunctional dentifrice: Amorphous polyphosphate a regeneratively active sealant with potent anti- Streptococcus mutans activity
2017
Abstract Objective In this study we demonstrate that inorganic polyphosphate (polyP) exhibits a dual protective effect on teeth: it elicits a strong antibacterial effect against the cariogenic bacterium Streptococcus mutans and, in form of amorphous calcium polyP microparticles (size of 100–400 nm), it efficiently reseals cracks/fissures in the tooth enamel and dentin. Methods Three different formulations of amorphous polyP microparticles (Ca-polyP, Zn-polyP and Sr-polyP) were prepared. Results Among the different polyP microparticles tested, the Ca-polyP microparticles, as a component of a newly developed formulation of a dentifrice, turned out to be most effective in inhibiting growth of …
