PURPOSE: To study whether ethmoidectomy predisposes the orbit to medial wall fracture with lesser trauma. METHODS: An interventional cadaver study of 5 heads (10 orbits); the left or right orbit was randomized to undergo endoscopic complete ethmoidectomy with the fellow orbit as control. Fractures were induced with direct globe trauma, and heads underwent CT scanning. Energy to induce fracture, peak orbital pressure at time of fracture, fracture pattern, and volume of herniated tissue were measured and analyzed...

Tingting Zou, Seiichiro Kizaki, Hiroshi Sugiyama
Capillary electrophoresis coupled with DNA 5 Texas Red labeling was used to investigate the ability of duocarmycin B2, Fe(II) peplomycin, and MNase to access the nucleosome. Distinct accessibility patterns of these species to the nucleosome were observed. Duocarmycin B2 was able to enter and react at the core region, although its alkylating efficiency decreased significantly. Intercalation of peplomycin in the nucleosomal core region was highly suppressed, but reaction sites located at the ends of the nucleosomal core remained accessible, which implied the flexibility of the core DNA end...

BACKGROUND: Stigmatization in society carries a high risk for development of psychopathology. Transgender persons are at particularly high risk for such stigmatization and social rejection by others. However, the neural correlates of ostracism in this group have not been captured. METHOD: Twenty transgender men (TM, female-to-male) and 19 transgender women (TW, male-to-female) already living in their gender identity and 20 cisgender men (CM) and 20 cisgender women (CW) completed a cyberball task assessing both exclusion and re-inclusion during functional magnetic resonance imaging (fMRI)...

This study characterized patterns and correlates of parent-youth agreement on social anxiety in youth with and without autism spectrum disorder (ASD). Participants (279 verbally-fluent youth aged 8-16 years, NASD = 144, NTD = 135) completed the SASC-R. Youth with ASD exhibited higher social anxiety across informants. While TD youth endorsed higher anxiety than did parents, self- and parent-reports did not differ in youth with ASD. For children with ASD, higher parent-youth agreement was associated with lower lifetime ASD symptoms and higher adaptive skills...

We are proposing mechanisms to account for the loss of viability (seed deterioration/ageing) and enhancement in seed quality (post-storage priming treatment). In order to understand the regulatory mechanism of these traits, we conducted controlled deterioration (CD) test for up to 8 d using primed mung bean seeds and examined how CD effects the expression of many genes, regulating the seed metabolism in relation to CD and priming. Germination declined progressively with increased duration of CD, and the priming treatment completely/partially reversed the inhibition depending on the duration of CD...

INTRODUCTION: Over 8500 United States Coast Guard (USCG) personnel were deployed in response to the Deepwater Horizon (DWH) oil spill; however, human respiratory effects as a result of spill-related exposures are relatively unknown. METHODS: USCG personnel who responded to the DWH oil spill were queried via survey on exposures to crude oil and oil dispersant, and acute respiratory symptoms experienced during deployment. Adjusted log binomial regressions were used to calculate prevalence ratios (PRs) and 95% confidence intervals (CI), investigating the associations between oil spill exposures and respiratory symptoms...

Human papillomavirus (HPV) type 18 is predominantly associated with the development of cervical adenocarcinomas, whereas data on HPV18 genetic variability in China are limited. HPV18 genetic variants were formed phylogenetic tree, including lineages A, B, and C. We aimed to evaluate the diversity of HPV18 genetic variants by sequencing the entire E6, E7 and L1 genes. Between 2012 and 2015, a total of 138 (0.8%, 138/17669) women with single HPV18 infection were selected in this study. Finally, we observed 122 HPV18 isolates of the complete E6-E7-L1 sequences, and obtained 36 distinct variation patterns which the accession GenBank numbers as KY457805-KY457840...

Exposing cells to a hypoxic environment leads to significant physiological and molecular alterations. Most of the hypoxic responses are regulated by the transcription factors known as hypoxia-inducible factors (HIFs). HIF1, a heterodimer of hypoxia-stabilized subunit HIF-1alpha and a constitutively expressed subunit HIF-1beta, serves as a key transcription factor that regulates gene expressions which are involved in cell growth, metabolism, and proliferation. The global expression patterns can be analyzed by utilizing RNA-Seq to understand the cellular alterations in hypoxia...

BACKGROUND: The mechanisms by which persistent atrial fibrillation (AF) terminates via localized ablation are not well understood. To address the hypothesis that sites where localized ablation terminates persistent AF have characteristics identifiable with activation mapping during AF, we systematically examined activation patterns acquired only in cases of unequivocal termination by ablation. METHODS AND RESULTS: We recruited 57 patients with persistent AF undergoing ablation, in whom localized ablation terminated AF to sinus rhythm or organized tachycardia...

Cucumber (Cucumis sativus L.) has a large, paternally transmitted mitochondrial genome. Cucumber plants regenerated from cell cultures occasionally show paternally transmitted mosaic (MSC) phenotypes, characterized by slower growth, chlorotic patterns on the leaves and fruit, lower fertility, and rearrangements in their mitochondrial DNAs (mtDNAs). MSC lines 3, 12, and 16 originated from different cell cultures all established using the highly-inbred, wild-type line B. These MSC lines possess different rearrangements and under-represented regions in their mtDNAs...

INTRODUCTION: Past research has shown that marijuana use occurs commonly in social situations for young adults, though few studies have examined the association between immediate social context and marijuana use patterns and associated problems. The current study examined the impact of demographics, marijuana use and problem use, alcohol use, craving, and social context on the likelihood of using marijuana with others via ecological momentary assessment (EMA). METHODS: College-student marijuana users (N=56) were recruited and completed a baseline assessment and training on the two-week signal-contingent EMA protocol...

The evolution, development and coloration of insect wings remains a puzzling subject in evolutionary research. In basal flying insects such as Odonata, genomic research regarding bauplan evolution is still rare. Here we focus on the world's largest odonate species-the "forest giant" Megaloprepus caerulatus, to explore its potential for looking deeper into the development and evolution of wings. A recently discovered cryptic species complex in this genus previously considered monotypic is characterized by morphological differences in wing shape and color patterns...
