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...

The interesting history of papillomavirus (PV) research has been reviewed before. The history of human papillomavirus (HPV) in head and neck region starts in 1901 when the contagious transmission of warty lesions into the mouth via oral sex was described, although the confirmation of their viral etiology had to wait until 1907. Ullman was the first to associate the human wart virus with laryngeal warts. Parsons and Kidd described the natural history of oral PV infections in rabbits already in 1942, but these findings were corroborated in humans only recently...

BACKGROUND: Effects of early-life stunting on adiposity development later in childhood are not well understood, specifically with respect to age in the onset of overweight and obesity. OBJECTIVES: We analyzed associations of infant stunting with prevalence of, incidence of, and reversion from high body mass index-for-age z score (BMIZ) later in life. We then estimated whether associations of infant stunting with BMIZ varied by sex, indigenous status, and rural or urban residence...

Phylogenetic analysis of Plasmodium parasites has indicated that their modern-day distribution is a result of a series of human-mediated dispersals involving transport between Africa, Europe, America, and Asia. A major outstanding question is the phylogenetic affinity of the malaria causing parasites Plasmodium vivax and falciparum in historic southern Europe-where it was endemic until the mid-20th century, after which it was eradicated across the region. Resolving the identity of these parasites will be critical for answering several hypotheses on the malaria dispersal...

INTRODUCTION: Neoadjuvant treatment might increase resectability of thymic epithelial tumors (TET). No standardized pathologic grading scheme for tumor response is available. Also, it is unclear whether radiologic treatment response can predict pathologic response. METHODS: Patients with unresectable TET who underwent neoadjuvant treatment before surgery at Mayo Clinic Rochester (1942-2014) were included. The pathologic tumor response grade (TRG) was based upon Mandard-grading (1994) ranging from TRG 1 (no viable tumor) to TRG 5 (no regression)...

OBJECTIVES: The Q80K polymorphism is a naturally occurring resistance-associated variant (RAV) in the hepatitis C virus (HCV) 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...

Molecular methods were used to determine the generic placement of two species of Entomophthorales known only from resting spores. Historically, these species would belong in the form-genus Tarichium, but this classification provides no information about phylogenetic relationships. Using DNA from resting spores, Zoophthora independentia, infecting Tipula (Lunatipula) submaculata in New York State, is now described as a new species and Tarichium porteri, described in 1942, which infects Tipula (Triplicitipula) colei in Tennessee, is transferred to the genus Zoophthora...

This article explores the medical use of techniques for psychological evaluation in the dispensarios de lactantes (infant and toddler clinics) in Buenos Aires within the framework of historical studies of psychology in Argentina. It analyzes the institutional environment in order to shed light on the framework of discourses within which the interest in controlling psychological development may be situated. It studies the tests used, the characteristics of application and the most significant results. It explores the vicissitudes of the professional field, in the light of which psychology was useful for consolidating the legitimacy of medical knowledge...

BACKGROUND: The coexistence of woody vegetation and grass is a key characteristic of savanna ecological balance. Gains in woody vegetation at the expense of grass can lead to changes in grazer and browser carrying capacities on the savannas. This study examined long-term change in woody cover at four study sites representative of the geology and rainfall in the Kruger National Park, South Africa. Scanned 1940/1942, 1968, and 1977 high spatial resolution (0.44-1.35 m) panchromatic aerial photographs were used, supplemented by 5 and 10 m resolution 1998 and 2012 panchromatic and red band grey scale digital SPOT images...

Since the introduction of penicillin into the clinic in 1942, antibiotics have saved the lives of millions of people around the world. While penicillin and other traditional broad spectrum antibiotics were effective as monotherapies, the inexorable spread of antibiotic resistance has made alternative therapeutic approaches necessary. Compound combinations are increasingly seen as attractive options. Such combinations may include: lethal compounds; synthetically lethal compounds; or administering a lethal compound with a nonlethal compound that targets a virulence factor or a resistance factor...

: Spouses tend to share habits and therefore have an increased risk of same diseases. We followed all married couples in Sweden, born 1902 to 1942, in hospital records from 1987 to 2002, and found that individuals whose spouse had a hip fracture had an increased risk of hip fracture. INTRODUCTION: The purpose of this study was to determine whether spouses of hip fracture patients have an elevated risk of hip fracture. METHODS: We performed a retrospective cohort study of all couples married for at least 5 years in Sweden and born between 1902 and 1942 (n = 904,451) and all patients registered with a hip fracture (n = 218,285) in the National Inpatients Register in Sweden from 1987 to 2002...

In Eukarya and Archaea, in addition to protein-only pseudouridine (Ψ) synthases, complexes containing one guide RNA and four proteins can also produce Ψ. Cbf5 protein is the Ψ synthase in the complex. Previously, we showed that Ψ's at positions 1940, 1942, and 2605 of Haloferax volcanii 23S rRNA are absent in a cbf5-deleted strain, and a plasmid-borne copy of cbf5 can rescue the synthesis of these Ψ's. Based on published reports of the structure of archaeal Cbf5 complexed with other proteins and RNAs, we identified several potential residues and structures in H...

As early as 1942, Epstein suggested a photoallergic concept for photodermatoses [s1]. Since then much progress has been made in understanding the pathophysiology of photodermatoses and their most common form, polymorphic light eruption (PLE) (1) (s2-s13). However, specific photoantigens that initiate PLE have not yet been identified. We hypothesize that PLE may be initiated by elements resulting from UV-induced damage to microbial communities of the skin, leading to a cascade of events eventually resulting in the skin rash of the disease...

Annual census data spanning seventy-five years document mortality and regeneration in a population of saguaro cactus (Carnegiea gigantea) in the Cactus Forest of the Rincon Mountain District of Saguaro National Park near Tucson, AZ. On 6 four-hectare plots, each saguaro was censused and a methodical search for new saguaros was conducted annually each year from 1942 through 2016, with the exception of 1955. Regeneration has been episodic with 828 plants established from 1959 through 1993 compared with 34 plants established between 1942 and 1958 and only three plants established after 1993...

Presents an obituary for Richard Michael Suzman, who died on April 16, 2015. Suzman was trained as a sociologist and anthropologist, but he was attracted to the approaches of demography and economics. He came to know a great deal about diverse fields of science, including health, physiology, psychology, genetics, and economics. He was a scientific leader who was on a quest to develop new transdisciplinary fields and to mobilize the best scientists to work in them. Suzman's passion for transdisciplinary science was fully expressed in his greatest achievement: the famous Health and Retirement Survey (HRS), which he initiated in 1988 and continued to guide and inspire...
