The study investigated musculotendinous adaptations in high and low performance triathletes compared to a control group, using ultrasonography to analyze the Achilles tendon and triceps surae muscles. Only the pennation angle of the medial gastrocnemius muscle showed statistically significant differences between the groups (p = 0.002), with higher values ​​in the control group compared to the triathletes. The pennation angle directly influences the capacity to generate force and muscular endurance, standing out for the greater cross-sectional area in efficiently packed muscle fibers. This study suggests that these adaptations may influence performance and predisposition to injuries in triathletes.

A novel meroterpenoid cabagranin D was isolated with related neolignans cabagranins A–C from the leaves of Piper cabagranum (Costa Rica). Cabagranins A–C represent the first examples of 3,3′-neolignans isolated from the plant genus Piper, and the meroterpenoid cabagranin D displays an unprecedented Diels–Alder conjugate of an unsubstituted phenylpropenone and α-phellandrene. Details of the full structural elucidation of these compounds and a discussion of their potential biosynthetic relationships are presented.

We identified (a) sources of and communication about HPV information and (b) factors (e.g., religious affiliations) related to information sources and communication regarding HPV among Hispanic/Latino college students attending US institutions. Applying a cross-sectional design, we recruited 209 participants from US colleges. Most participants used healthcare professionals for their sources and communication about HPV-related information. Respondents who were practicing Catholics tended to use the Internet and healthcare professionals as their sources for HPV-related information. Healthcare professionals, TV, schoolteachers, same-sex friends, and family members affected participants' HPV vaccination, knowledge, and attitudes. Religious faith may influence information-seeking behaviors and requires more research.

Nursing student failure affects the number of nurses prepared to enter practice. Currently, there is a dearth of literature examining program factors that influence clinical failure. This survey of nursing directors used multiple linear regression to determine if the percentage of adjunct faculty, the number of simulation hours, and the number of clinical hours affect clinical failure rates. The results of the study showed a positive correlation between each of the independent variables and the percentage of student clinical failures.

Phylogenomic investigations of biodiversity facilitate the detection of fine-scale population genetic structure and the demographic histories of species and populations. However, determining whether or not the genetic divergence measured among populations reflects species-level differentiation remains a central challenge in species delimitation. One potential solution is to compare genetic divergence between putative new species with other closely related species, sometimes referred to as a reference-based taxonomy. To be described as a new species, a population should be at least as divergent as other species. Here, we develop a reference-based taxonomy for Horned Lizards (Phrynosoma; 17 species) using phylogenomic data (ddRADseq data) to provide a framework for delimiting species in the Greater Short-horned Lizard species complex (P. hernandesi). Previous species delimitation studies of this species complex have produced conflicting results, with morphological data suggesting thatP. hernandesiconsists of five species, whereas mitochondrial DNA support anywhere from 1 to 10 + species. To help address this conflict, we first estimated a time-calibrated species tree forP. hernandesiand close relatives using SNP data. These results support the paraphyly ofP. hernandesi;we recommend the recognition of two species to promote a taxonomy that is consistent with species monophyly. There is strong evidence for three populations withinP. hernandesi, and demographic modeling and admixture analyses suggest that these populations are not reproductively isolated, which is consistent with previous morphological analyses that suggest hybridization could be common. Finally, we characterize the population-species boundary by quantifying levels of genetic divergence for all 18Phrynosomaspecies. Genetic divergence measures for western and southern populations ofP. hernandesifailed to exceed those of otherPhrynosomaspecies, but the relatively small population size estimated for the northern population causes it to appear as a relatively divergent species. These comparisons underscore the difficulties associated with putting a reference-based approach to species delimitation into practice. Nevertheless, the reference-based approach offers a promising framework for the consistent assessment of biodiversity within clades of organisms with similar life histories and ecological traits.

This study presents a methodology to reveal traces of viral particles, as aerosol with known chemical and molecular structure, in a sample by means of photon and electron interactions. The method is based on Monte Carlo simulations and on the analysis of photon-electron fluxes-spectra through energy channels counts as a function of different aerosol viral concentrations in the air sample and looking at the peculiar photon/electron interactions with the potential abnormal atomic hydrogen (H), oxygen (O), carbon (C), and phosphorus (P) compositions present in the air sample as a function of living and nonliving matter with PO4 group RNA/DNA strands in a cluster configuration.

The study presented hereafter shows a new methodology to reveal traces of polyethylene (the most common microplastic particles, known as a structure of C2H4) in a sample of ocean water by the irradiation of a 50 keV, 1 µA electron beam. This is performed by analyzing the photon (produced by the electrons in water ) fluxes and spectra (i.e. fluxes as a function of photon energy) at different types of contaminated water with an adequate device and in particular looking at the peculiar interactions of electrons/photons with the potential abnormal atomic hydrogen (H), oxygen (O), carbon (C), phosphorus (P) compositions present in the water, as a function of living and not living organic organisms with a PO4 group RNA/DNA strands in a cluster configuration through a volumetric cells grid.

Addie Kinsinger served AECT and all its members for more than seven decades. Her dedication to the teaching/learning profession and her love for the educators that kept that community of educators in the classroom lived in her heart. She was driven to serve. As a library-media specialist, she loved books and film and children and parents and teachers. And she fell in love with instructional television, its power for learning and its appeal for generating the very basic learning needs of all people: curiosity for the world we live in, discovery of new ideas, and the amazement that comes from the learning experience.

My dad was often called “leader,” as was his father before him and who knows others in the line of “Millers” in East Lampeter Township, Pennsylvania. The Millers were often elected to local offices, chosen to represent the congregation on the church council, and recruited to help solve problems in the communities they served. I particularly remember a time when my father negotiated a solution to a problem generated by changes in state health regulations. My dad was a dairyman, not a dairy farmer but rather an employee of a dairy that processed milk for sale. In the mid-fifties, Pennsylvania regulations regarding storage of milk at the farm before delivery to the dairy forced the farmer to revise storage from milk cans (those collector’s items we often see revamped into planters) to refrigerated storage tanks, delivering the milk to the processing dairy in tank trucks. As might be expected, many of the large dairy farms that were the source of fresh milk were Amish farms, where electricity was forbidden by their religion. Starting with the respect held by the Amish for “the Millers,” my father was able to convince the Amish farmers that there must be a way to allow access to electricity ensuring refrigerated milk storage. The solution was simple. The Amish were forbidden to use electricity in their daily living but not in their livelihoods. Installation of generators to refrigerate the milk, controlled by the farmers themselves and not connected to the “Englisher’s” world, were the answer. At the heart of the leadership demonstrated by my dad to resolve this issue was his ability to listen, to hear the needs of both the Amish farmers and the State health officers, and to bring them together to share their needs and find a way to satisfy both sides. I watched both my father and my grandfather as they provided similar services to community. And by the time I was a teenager, I was acting in similar leadership roles in school, church, 4-H, Y-Teens. As I look back, I was copying leadership as I had learned it from my first mentor, my father.
