Genome report: Genome sequence of tuliptree scale, Toumeyella liriodendri (Gmelin), an ornamental pest insect.

Scale insects are of interest both to basic researchers for their unique reproductive biology and to applied researchers for their pest status. In spite of this interest, there remain few genomic resources for this group of insects. To begin addressing this lack of data, we present the genome sequence of tuliptree scale, Toumeyella liriodendri (Gmelin) (Hemiptera: Coccomorpha: Coccidae).

The U1-70K and SRSF1 interaction is modulated by phosphorylation during the early stages of spliceosome assembly.

In eukaryotes, pre-mRNA splicing is vital for RNA processing and orchestrated by the spliceosome, whose assembly starts with the interaction between U1-70K and SR proteins. Despite the significance of the U1-70K/SR interaction, the dynamic nature of the complex and the challenges in obtaining soluble U1-70K have impeded a comprehensive understanding of the interaction at the structural level for decades. We overcome the U1-70K solubility issues, enabling us to characterize the interaction between U1-70K and SRSF1, a representative SR protein.

An annotated and illustrated catalog of the primary type material of Hemiptera deposited in the Florida State Collection of Arthropods.

The Florida State Collection of Arthropods (FSCA) is one of the largest and most diverse insect collections in North America and the largest in the southeastern United States with over twelve million curated specimens and significant amounts of materials in bulk collections and other unprocessed samples. The order Hemiptera currently comprises approximately 95,000 species in three suborders. The FSCA houses type material in the auchenorrhynchan families Cicadidae, Cicadellidae, Cixiidae, Delphacidae, Derbidae, and Membracidae; the heteropteran families Coreidae, Corixidae, Curaliidae, Lygaeidae, Miridae, Pentatomidae, Reduviidae, Schizopteridae, Scutelleridae, and Tingidae; the sternorrhynchan families Aleyrodidae, Aphalaridae, Aphididae, Coccidae, Diaspididae, Matsucoccidae, Pseudococcidae, Phacopteronidae, and Triozidae.

Conspicuous stripes on prey capture attention and reduce attacks by foraging jumping spiders.

Many animals avoid predation using aposematic displays that pair toxic/dangerous defences with conspicuous achromatic warning patterns, such as high-contrast stripes. To understand how these prey defences work, we need to understand the decision-making of visual predators. Here we gave two species of jumping spiders ( and ) choice tests using live termites that had their back patterns manipulated using paper capes (solid white, solid black, striped).

Juvenile leg autotomy predicts adult male morph in a New Zealand harvestman with weapon polymorphism.

Intraspecific weapon polymorphisms that arise via conditional thresholds may be affected by juvenile experience such as predator encounters, yet this idea has rarely been tested. The New Zealand harvestman has three male morphs: majors (alphas and betas) are large-bodied with large chelicerae used in male-male contests, while minors (gammas) are small-bodied with small chelicerae and scramble to find mates. Individuals use leg autotomy to escape predators and there is no regeneration of the missing leg.

Peptides that Mimic RS repeats modulate phase separation of SRSF1, revealing a reliance on combined stacking and electrostatic interactions.

Phase separation plays crucial roles in both sustaining cellular function and perpetuating disease states. Despite extensive studies, our understanding of this process is hindered by low solubility of phase-separating proteins. One example of this is found in SR and SR-related proteins.

Sexually dimorphic dorsal coloration in a jumping spider: testing a potential case of sex-specific mimicry.

To avoid predation, many animals mimic behaviours and/or coloration of dangerous prey. Here we examine potential sex-specific mimicry in the jumping spider . Previous work proposed that males' conspicuous dorsal coloration paired with characteristic leg-waving (i.

Factors associated with cognitive impairment during the first year of treatment for nonmetastatic breast cancer.

Background: Women with breast cancer are more likely to develop cognitive impairment (CI), insomnia, fatigue, and mood disturbance than individuals with other cancers. The main objectives of this study were to establish the prevalence of CI and examine the relationships between CI, insomnia, fatigue, and mood over the first year of breast cancer treatment.

Methods: Participants were recruited after diagnosis and completed validated measures of insomnia, objective and perceived CI, fatigue, and mood disturbance at four time points during the first year of treatment.

Muscle mass drives cost in sexually selected arthropod weapons.

Sexually selected weapons often function as honest signals of fighting ability. If poor-quality individuals produce high-quality weapons, then receivers should focus on other, more reliable signals. Cost is one way to maintain signal integrity.

Surgical treatment choices for breast cancer in Newfoundland and Labrador: a retrospective cohort study.

Background: Mastectomy is often chosen by women for treatment of breast cancer, even when breast-conserving surgery (BCS) is an option. Newfoundland and Labrador has a high mastectomy rate. We documented the number of breast cancers over a given period in the province and their related surgical treatments, and explored the impact of several variables on surgical choice.

Specialists and generalists coexist within a population of spider-hunting mud dauber wasps.

Individual foraging specialization describes the phenomenon where conspecifics within a population of generalists exhibit differences in foraging behavior, each specializing on different prey types. Individual specialization is widespread in animals, yet is understudied in invertebrates, despite potential impacts to food web and population dynamics (Hymenoptera: Sphecidae) is an excellent system to examine individual specialization. Females of these mud dauber wasps capture and paralyze spiders which they store in mud nests to provision their offspring.

Breast cancer surgical treatment choices in Newfoundland and Labrador, Canada: Patient and surgeon perspectives.

Background: Breast cancer remains the second-leading cause of cancer death among Canadian women. Treatment for breast cancer often includes surgery. Many women have a choice between mastectomy (MT; removal of the entire breast) or breast conserving surgery (BCS; removal of the tumour and some noncancerous breast tissue) followed by radiation.

Frequent misdirected courtship in a natural community of colorful Habronattus jumping spiders.

Male courtship display is common in many animals; in some cases, males engage in courtship indiscriminately, spending significant time and energy courting heterospecifics with whom they have no chance of mating or producing viable offspring. Due to high costs and few if any benefits, we might expect mechanisms to evolve to reduce such misdirected courtship (or 'reproductive interference'). In Habronattus jumping spiders, males frequently court heterospecifics with whom they do not mate or hybridize; females are larger and are voracious predators, posing a severe risk to males who court indiscriminately.

Impact of Postoperative Adjuvant Chemotherapy Following Long-course Chemoradiotherapy in Stage II Rectal Cancer.

Objectives: Use of adjuvant chemotherapy (AC) following neoadjuvant chemoradiation (nCRT) is controversial in rectal cancer (RC). We assessed a multi-institutional database to determine if there was benefit from AC for pathologic stage II RC patients and whether the addition of oxaliplatin to fluoropyrimidine (OXAC) therapy impacted outcomes.

Materials And Methods: We included patients who underwent nCRT and had pathologic stage II (ypT3/4 ypN0) tumors.

PROSPECT Eligibility and Clinical Outcomes: Results From the Pan-Canadian Rectal Cancer Consortium.

Background: The PROSPECT trial (N1048) is evaluating the selective use of chemoradiation in patients with cT2N1 and cT3N0-1 rectal cancer undergoing sphincter-sparing low anterior resection. We evaluated outcomes of PROSPECT-eligible and -ineligible patients from a multi-institutional database.

Patients And Methods: Data from patients with locally advanced rectal cancer who received chemoradiation and low anterior resection from 2005 to 2014 were retrospectively collected from 5 Canadian centers.

Predictors of Pathologic Complete Response After Neoadjuvant Treatment for Rectal Cancer: A Multicenter Study.

Background: Pathologic complete response (pCR) to neoadjuvant chemoradiation (CRT) for rectal cancer is associated with better long-term outcomes, and is used as an early indicator of response to novel agents. To assess the rate and predictors of pCR, we performed a retrospective multicenter study involving 5 Canadian cancer centers.

Patients And Methods: Cancer registries identified consecutive patients with locally advanced rectal adenocarcinoma from the Tom Baker Cancer Centre, Cross Cancer Institute, British Columbia Cancer Agency, Ottawa Hospital Cancer Centre, and the Dr H.

Delineation of candidate genes responsible for structural brain abnormalities in patients with terminal deletions of chromosome 6q27.

Patients with terminal deletions of chromosome 6q present with structural brain abnormalities including agenesis of corpus callosum, hydrocephalus, periventricular nodular heterotopia, and cerebellar malformations. The 6q27 region harbors genes that are important for the normal development of brain and delineation of a critical deletion region for structural brain abnormalities may lead to a better genotype-phenotype correlation. We conducted a detailed clinical and molecular characterization of seven unrelated patients with deletions involving chromosome 6q27.

Wheat straw biomass: a resource for high-value chemicals.

Two methods are proposed for increasing the commercial value of wheat straw based on its chemical constituents. The first method involves the determination and extraction of the major organic components of wheat straw, and the second involves those found and extracted in the aqueous and viscous biooils derived from the straw by fast pyrolysis. We used pyrolysis-field ionization mass spectrometry to identify the fine chemicals, which have high commercial values.

Use of bisphosphonates in metastatic breast cancer: single institution review at the Dr. H. Bliss Murphy Cancer Centre.

Purpose: Bone metastases occur in 65-75% of patients with metastatic breast cancer. These patients are at risk of developing skeletal-related events (SREs). SREs are defined as any pathological fracture, spinal cord compression, hypercalcemia, and surgery or radiation required for treatment of bone metastases.

Atrazine exposure leads to altered growth of HepG2 cells.

Atrazine is one of the most commonly used herbicides in the United States. While effective on target plants, it has been associated with harmful health effects in non-target organisms such as fish, amphibians and mammals. In this study, growth effects on human liver cells were determined after exposure to increasing concentrations of this herbicide.
