(R)-(+)-γ-Decalactone is Conserved in North America as a Pheromone Component of Osmoderma eremicola (Coleoptera: Scarabaeidae) and a Kairomone of Elater abruptus (Coleoptera: Elateridae).

The scarab genus Osmoderma (Coleoptera: Scarabaeidae) includes several large species called hermit beetles that develop within dead and decaying hardwood trees. Males of at least three Palearctic species produce the aggregation-sex pheromone (R)-(+)-γ-decalactone, including the endangered O. eremita (Scopoli).

Seed mucilage in temperate grassland species is unrelated to moisture requirements.

Myxospermy, the release of seed mucilage upon hydration, plays multiple roles in seed biology. Here, we explore whether seed mucilage occurs in a suite of temperate grassland species to test if the prevalence of species producing seed mucilage is associated with habitat type or seed characteristics. Seventy plant species found in wet or dry North American temperate grasslands were tested for the presence of seed mucilage through microscopic examination of seeds imbibed with histochemical stain for mucilage.

Nutrition and outcomes in venovenous extracorporeal membrane oxygenation: An observational cohort study.

Background: Overfeeding and underfeeding are associated with negative outcomes during critical illness. The purpose of this retrospective study was to assess the association between nutrition intake and outcomes for patients receiving venovenous (VV) extracorporeal membrane oxygenation (ECMO).

Methods: Adults who received VV ECMO August 2017 to June 2020 were screened.

Human iPSC-derived photoreceptor transplantation in the cone dominant 13-lined ground squirrel.

Several retinal degenerations affect the human central retina, which is primarily comprised of cones and is essential for high acuity and color vision. Transplanting cone photoreceptors is a promising strategy to replace degenerated cones in this region. Although this approach has been investigated in a handful of animal models, commonly used rodent models lack a cone-rich region and larger models can be expensive and inaccessible, impeding the translation of therapies.

Neural control of fluid homeostasis is engaged below 10°C in hibernation.

Thirteen-lined ground squirrels (Ictidomys tridecemlineatus) hibernate for several months each winter without access to water, but the mechanisms that maintain fluid homeostasis during hibernation are poorly understood. In torpor, when body temperature (T) reaches 4°C, squirrels decrease metabolism, slow heart rate, and reduce plasma levels of the antidiuretic hormones arginine vasopressin (AVP) and oxytocin (OXT). Squirrels spontaneously undergo interbout arousal (IBA) every 2 weeks, temporarily recovering an active-like metabolism and a T of 37°C for up to 48 h.

Evolution of chemosensory genes in Colorado potato beetle, Leptinotarsa decemlineata.

Associating with plant hosts is thought to have elevated the diversification of insect herbivores, which comprise the majority of global species diversity. In particular, there is considerable interest in understanding the genetic changes that allow host-plant shifts to occur in pest insects and in determining what aspects of functional genomic diversity impact host-plant breadth. Insect chemoreceptors play a central role in mediating insect-plant interactions, as they directly influence plant detection and sensory stimuli during feeding.

Racial and ethnic disparities in knowledge, attitudes, and invitation to participate in clinical trials among cancer survivors in the United States: An analysis of the 2020 U.S. HINTS.

Background: Despite the use of clinical trials to provide gold-standard evidence of cancer treatment and intervention effectiveness, racial/ethnic minorities are frequently underrepresented participants. Our objective was to evaluate racial/ethnic differences in knowledge and attitudes towards clinical trials among U.S.

Understanding poverty through virtual simulation: implications for student clinical practice.

Background: Competency-based education among baccalaureate nursing students is emerging based on American Association of Colleges of Nursing Essentials. With the impact of COVID-19 on nursing education and AACN recommendations, changes were required to provide alternative modes of delivery and means of assessment.

Purpose: Virtual poverty simulation data is limited.

Common analysis of direct RNA sequencinG CUrrently leads to misidentification of mC at GCU motifs.

RNA modifications, such as methylation, can be detected with Oxford Nanopore Technologies direct RNA sequencing. One commonly used tool for detecting 5-methylcytosine (mC) modifications is Tombo, which uses an "Alternative Model" to detect putative modifications from a single sample. We examined direct RNA sequencing data from diverse taxa including viruses, bacteria, fungi, and animals.

Overlapping Localization of MAP65-2, -6, and -7 in Arabidopsis Hypocotyl Cells.

Microtubules are essential components of eukaryotic cells. Myriad proteins associate with microtubules to facilitate the organization and operation of microtubule arrays. Various M icrotubule A ssociated P roteins (MAPs) assist the assembly and function of mitotic spindles and interphase arrays.

Board Leaders' Perspectives of the Impact of Nurses on Boards.

Objective: The purpose of the study was to explore the impact of nurses on boards (NOBs) from the perspectives of board leaders who are not nurses.

Background: Research about the impact of NOBs derives from nurses' recall of board experiences. No studies explore the impact of NOBs from perspectives other than nurses.

A Qualitative Analysis of Latina Migrant Farmworkers' Perception of Mental Health: Voices From Wisconsin.

Introduction: Despite evidence showing Latinos' high prevalence of mental health, little is known about Latina migrant farmworkers' mental health experiences, especially those working in Midwestern states. Considering the multiple vulnerabilities observed among Latina migrant farmworkers, it is necessary to gain insight from own accounts and perceptions of mental health and mental health-seeking experiences.

Method: A qualitative descriptive approach, using in-depth semi-structured interviews with open-ended questions, served to retrieve data from 34 Latina migrant farmworkers.
