Ecotoxicity testing is a crucial component of chemical risk assessment. Still, due to methodological difficulties related to controlling exposure concentrations over time, data on long-term effects of organic chemicals at low concentrations are limited. The aim of the present study was therefore to test the applicability of passive dosing to maintain stable concentrations of the organochlorine bacteriocide triclosan in the water phase during a 6-week multi-generation population development test with the harpacticoid copepod Nitocra spinipes...

BACKGROUND: Parents are a major supplier of alcohol to adolescents, yet there is limited research examining the impact of this on adolescent alcohol use. This study investigates associations between parental supply of alcohol, supply from other sources, and adolescent drinking, adjusting for child, parent, family and peer variables. METHOD: A cohort of 1927 adolescents was surveyed annually from 2010 to 2014. Measures include: consumption of whole drinks; binge drinking (>4 standard drinks on any occasion); parental supply of alcohol; supply from other sources; child, parent, family and peer covariates...

The Central American tribe Neaenini, originally comprising only the monobasic genus Neaenus Fowler, was thought to be transitional between Cercopinae and Aphrophorinae. The genus is here enlarged by 5 (1 unnamed)  additional species including 2 in a distinctive new subgenus Neaniskus. Keys are presented to 5 species of Neaenus, to 12 allied Neotropical genera and their 57 species: 12 of Tomaspisinella Lallemand, 1927 (=Hemitomaspis Lallemand, 1949, syn.nov. and 3 distinctive new subgenera Meretricula, Merinx and Merulatomus), 14 species of Microsargane Fowler, 1897 (=Ecothera Melichar, 1915, syn...

A new species of Falsopodabrus Pic, 1927 is described, Falsopodabrus tridentatus Yang, sp. n. (Yunnan, China). Geometric morphometric analyses based on the shapes of pronotum and hind wing and comparisons with two sibling species, Falsopodabrus himalaicus Wittmer, 1974 and Falsopodabrus martensi (Wittmer, 1979), support the valid status of the new species, also confirmed by the characters of tarsal claws. In addition to Falsopodabrus himalaicus and Falsopodabrus martensi, Falsopodabrus kostali Švihla, 2004 and Falsopodabrus rolciki Švihla, 2004 are recorded from China for the first time...

AIM: Conformity to traditional masculine gender norms may deter men's help-seeking and/or impact the services men engage. Despite proliferating research, current evidence has not been evaluated systematically. This review summarises findings related to the role of masculinity on men's help-seeking for depression. METHOD: Six electronic databases were searched using terms related to masculinity, depression and help-seeking. Titles and abstracts were reviewed and data systematically extracted and examined for methodological quality...

BACKGROUND: The monotypic genus Wenchengia (Lamiaceae) has been thought to be endemic to Hainan, China. This paper reports on historic records of Wenchengia alternifolia collected from Vietnam. The recent recuration and modernisation of the Paris herbarium greatly facilitated this discovery. NEW INFORMATION: During preparatory work supporting the account for the Lamiaceae of the Flora of Thailand, three specimens of Wenchengia from central Vietnam were found in the Herbarium of the Musuem National d'Histoire Naturelle in Paris (P), and subsequently two duplicates were found in the Herbarium at Kew (K, abbreviations following Thiers 2016)...

David Kasner, MD (1927-2001), used his extensive dissections of eye bank eyes and experiences in teaching cataract surgery to resident physicians to realize that excision of vitreous when present in the anterior chamber of eyes undergoing cataract surgery was preferable to prior intraoperative procedures. Noting that eyes tolerated his maneuvers, he then performed planned subtotal open-sky vitrectomies; first on a traumatized eye in 1961, then on two eyes of patients with amyloidosis (1966-1967). The success of these operations was noted by others, most particularly Robert Machemer, MD...

Einstein was wrong with his 1927 Solvay Conference claim that quantum mechanics is incomplete and incapable of describing diffraction of single particles. However, the Einstein-Podolsky-Rosen paradox of entangled pairs of particles remains lurking with its 'spooky action at a distance'. In molecules quantum entanglement can be viewed as basis of both chemical bonding and excitonic states. The latter are important in many biophysical contexts and involve coupling between subsystems in which virtual excitations lead to eigenstates of the total Hamiltonian, but not for the separate subsystems...

Plagioporus hageli n. sp. is described from the intestine of Oncorhynchus mykiss (Walbaum) collected from the River Yuba, California, USA. Of the accepted, nominal species of Plagioporus Stafford, 1904 from the Nearctic, the new species is morphologically similar to three intestinal species from the western USA parasitising diadromous fishes, including Plagioporus shawi (McIntosh, 1939), Plagioporus kolipinskii Tracey, Choudhury, Cheng & Ghosh, 2009 and Plagioporus siliculus Sinitsin, 1931, and is also similar to Plagioporus serotinus Stafford, 1904 from catostomids from eastern Canada...

Sustained autonomic arousal during eye contact could cause the impairments in eye contact behavior commonly seen in autism. The aim of the present study was to re-analyze the data from a study by Kaartinen et al. (J Autism Develop Disord 42(9):1917-1927, 2012) to investigate the habituation of autonomic arousal responses to repeated facial stimuli and the correlations between response habituation and social impairments among children with and without ASD. The results showed that among children with ASD, the smaller the habituation was, specifically in responses to a direct gaze, the more the child showed social impairments...

Ultrastructural description of Ceratomyxa aegyptiaca Yemmen, Marton, Eszterbauer and Bahri, 2012 infecting the gallbladder of Solea aegyptiaca Chabanaud, 1927 from a tunisian north-east costal lagoon, was presented in this study. The primary cell was attached to the gallbladder epithelium and presented at one side cytoplasmic projections corresponding to pinocytotic invaginations. Netherless, early sporogonic stages development was carried with contact to the epithelial cells of gallbladder. Immature spores were identified in early sporoblasts by their valvogenic, capsulogenic and binucleated sporoplasmic cells...

A molecular phylogeny of the Afrotropical anuran genus Amietia based on 323 16S sequences indicates that there are 19 species, including four not yet described. No genetic material was available for the nominal A. inyangae. We consider them to represent full species, and define them based on 16S genetic distances, as well as differences in morphology, tadpoles and advertisement call where known. An analysis based on two mitochondrial and two nuclear genes (12S, 16S, 28S and tyrosinase exon 1), from 122 samples, confirmed the phylogenetic relationships suggested by the 16S tree...

Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud was first typified in 1927. With the help of electron microscopy, it has been elucidated that CRP arises due to aberrant keratinization. However, till date, there is no clear consensus on the etiologic trigger for CRP. Prevailing postulates include a bacterial trigger by Dietzia papillomatosis (type strain N 1280(T)), an exaggerated cutaneous response to Malassezia furfur, an endocrine basis stemming from insulin resistance, ultraviolet light-induced epidermal change, amyloid deposition, and a loss-of-function mutation in keratin 16...

The prokaryotic genus name Verticia Vandamme et al. 2015 is illegitimate because it is a later homonym of the insect genus name Verticia Malloch, 1927 [Principle 2, Rule 51b(4) of the Prokaryotic Code (2008 Revision)]. This name is therefore not a correct name (Principle 6) and a replacement generic name must be proposed (Rule 54).

Professor Giuseppe Moscati (1880-1927) was canonized by the Catholic Church in 1987. This act recognized the extraordinary qualities of a doctor who, considering his work as a "sublime mission", dedicated his life to helping the sick. The fame of the "Holy doctor" or "doctor of the poor", as people called him, was soon widespread and, immediately after his death, made him the subject of several biographies. These treatises, mainly written by religious hagiographers, have little analyzed Moscati as a doctor and scientist, or, in rare cases, privileged the description of his medical career, touching only marginally salient aspects of his work as a scientist and researcher...

Magnetic resonance spectroscopy (MRS) is a well established modality for investigating tissue metabolism in vivo. In recent years, many efforts by the scientific community have been directed towards the improvement of metabolite detection and quantitation. Quantum mechanics simulations allow for investigations of the MR signal behaviour of metabolites; thus, they provide an essential tool in the optimization of metabolite detection. In this review, we will examine quantum mechanics simulations based on the density matrix formalism...
