A gene co-expression network (GEN) was generated using a dual RNA-seq study with the fungal pathogen Aspergillus flavus and its plant host Zea mays during the initial 3 days of infection. The analysis deciphered novel pathways and mapped genes of interest in both organisms during the infection. This network revealed a high degree of connectivity in many of the previously recognized pathways in Z. mays such as jasmonic acid, ethylene, and reactive oxygen species (ROS). For the pathogen A. flavus, a link between aflatoxin production and vesicular transport was identified within the network...

A catalogue of all named Nepticulidae and Opostegidae is presented, including fossil species. The catalogue is simultaneously published online in the scratchpad and in Catalogue of Life ( We provide a historical overview of taxonomic research on Nepticuloidea and a brief 'state of the art'. A DNA barcode dataset with 3205 barcodes is made public at the same time, providing DNA barcodes of ca. 779 species, of which 2563 are identified as belonging to 444 validly published species...

Alfonso Luis Herrera (1868-1942) was a Mexican biologist, and significant as the principal promoter of Darwinian thought in that country. However, Herrera's thinking went beyond the evolution of living beings, and extended to the question of the origin of life itself and the place of living phenomena in the larger context of the cosmos. Perhaps more significantly, though now largely forgotten, Herrera was among the first to embark on an experimental program to understand the origin of life, one which may be seen as foundational for later workers, most notably Sidney Fox and Alexander Oparin, and which has been resuscitated recently...

In human rod-mediated vision, threshold for small, brief flashes rises in proportion to the square root of adapting luminance at all but the lowest and highest adapting intensities. A classical signal detection theory from Rose (1942, 1948) and de Vries (1943) attributed this rise to the perceptual masking of weak flashes by Poisson fluctuations in photon absorptions from the adapting field. However, previous work by Brown and Rudd (1998) demonstrated that the square-root law also holds for suprathreshold brightness judgments, a finding that supports an alternative explanation of the square-root sensitivity changes as a consequence of physiological adaptation (i...

OBJECTIVES: The Q80K polymorphism is a naturally occurring resistance-associated variant in the hepatitis C virus (HCV) nonstructural protein 3 (NS3) region and is likely transmissible between hosts. This study describes the Q80K origin and prevalence among HCV risk groups in the Netherlands and examines whether Q80K is linked to specific transmission networks. DESIGN AND METHODS: Stored blood samples from HCV genotype 1a-infected patients were used for PCR and sequencing to reconstruct the NS3 maximum likelihood phylogeny...

: Editor's note: From its first issue in 1900 through to the present day, AJN has unparalleled archives detailing nurses' work and lives over more than a century. These articles not only chronicle nursing's growth as a profession within the context of the events of the day, but they also reveal prevailing societal attitudes about women, health care, and human rights. Today's nursing school curricula rarely include nursing's history, but it's a history worth knowing. To this end, From the AJN Archives highlights articles selected to fit today's topics and times...

We report on a tunable noise-like pulse (NLP) generation in a mode-locked Tm fiber laser with a SESAM. A tuning range of 1895-1942 nm, while keeping the spectral bandwidth of 10-19 nm under NLP mode-locked operation, was obtained by a tunable filter based on chromatic dispersion of telescope lenses. At the center wavelength of 1928 nm, the maximum output power of 195 mW with the spectral bandwidth of 18.9 nm was obtained. The repetition rate was 20.5 MHz and the corresponding pulse energy was 9.5 nJ. To our knowledge, this is the first report of a tunable NLP mode-locked laser based on chromatic dispersion of a lens system...

Temnomastax spielmanni Olivier, 2014 n. syn. is proposed as new synonym of Eumastacops nemorivaga Rehn & Rehn, 1942. New distribution records in Peru and Colombia are provided for the following four species: Eumastax nigrovittata Descamps, 1979; Paramastax nigra (Scudder, 1875); Pseudomastax nigroplagiata Descamps, 1970; and Pseudomastax personata (Bolívar, 1881). New information on the distribution of Paramastax flavovittata Descamps, 1973 and E. nemorivaga is added, resulting in the expansion of the geographic distribution...

Many species have suffered large population declines due to the anthropogenic influence on ecosystems. Understanding historical population trends is essential for informing best efforts to preserve species. We propose a new method to reconstruct the past structure of a regional species pool, based on historical naturalist literature. Qualitative information collected from annotated checklists and reports can be relevant to identify major long-term community changes. We reviewed ornithological literature on the Camargue, the largest wetland in France...

CONTEXT: More than half of the bipolar disorder (BD) cases have an additional diagnosis; one of the most difficult to manage is obsessive-compulsive disorder (OCD). Although some authors recently investigated the co-occurrence of anxiety and BD, the topic remains insufficiently studied. The current study aimed to investigate differences in comorbid OCD between BD-I and BD-II. EVIDENCE ACQUISITION: A systematic review and meta-analysis was conducted on the prevalence and predictors of comorbid BD-I/BD-II and OCD...

BACKGROUND: Visceral leishmaniasis, commonly known as kala-azar in India, is a global public health problem. In Southeast Asia, Bangladesh, Bhutan, India, Nepal, Sri Lanka and Thailand are endemic for visceral leishmaniasis. The role of sandflies as the vector of kala-azar was first confirmed in 1942 in India. Insecticide resistance in Phlebotomus argentipes Annandale and Brunetti, the vector of kala-azar in the Indian subcontinent, was first reported in 1987 in Bihar, India. This article provides a scoping review of the studies undertaken from 1959 to 2015 on insecticide resistance in P...

The chromosomal region, in which the GBA gene is located, is structurally subject to misalignments, reciprocal and nonreciprocal homologous recombination events, leading to structural defects such as deletions, duplications and gene-pseudogene complex rearrangements causing Gaucher Disease (GD). Interestingly deletions and duplications, belonging to the heterogeneous group of structural defects collectively termed Copy Number Variations (CNVs), together with gene-pseudogene complex rearrangements represent the main cause of pitfalls in GD mutational analysis...

Species of North American Cybaeus L. Koch (Araneae: Dictynoidea: Cybaeidae) are classified in Holarctic and Californian clades. We review the Nearctic species of the Holarctic clade of these common moist-forest spiders. Twenty-one species grouped in informal tetricus (nine species) and angustiarum (twelve species) groups based on female genitalic characters are recognized, including four new species endemic to the western Nearctic: C. rothi Bennett sp. nov. (tetricus group) and C. charlesi Bennett sp. nov., C...

Dasypus kappleri is the largest species of the genus Dasypus and is restricted to the Amazonian rainforest biome. Over the last century, related taxa have been described and synonymized without comprehensive analyses, and the current classification involving two subspecies, Dasypus k. kappleri and Dasypus k. pastasae, has never been revised. The aim of this work is to clarify the taxonomy of Dasypus kappleri through integrative morphological and morphometric analyses. We examined 70 specimens housed in scientific collections as well as photographs of the type specimens of five nominal taxa...
