Article Synopsis
  • The shift from foraging to farming in the ancient Northeast Baltic reveals significant complexities and regional differences that are not fully understood.
  • This study combines multiple scientific analyses to provide a comprehensive view of early farming practices in the 3rd millennium cal BCE, emphasizing the coexistence of different dietary habits among communities.
  • Rather than a straightforward transition to farming, a diverse system emerged with local hunter-gatherers maintaining their lifestyles while newcomers practiced mixed economies, indicating a long-lasting interaction between these groups without full adoption of agriculture.

Undergraduate research is a valuable experience that increases the likelihood of a STEM major to continue on to postgraduate training in their field. For students from groups underrepresented in the biomedical sciences, a strong mentoring relationship during this undergraduate period is a key component in preparing them for the next stage of their education and can have a significant influence on their ability to persist in the pipeline. Although the ideal scenario to increase the diversity of the biomedical workforce is to provide more BIPOC (Black, Indigenous, People of Color) faculty mentors for our undergraduates, we also need to develop strategies to provide strong mentoring experiences for our BIPOC students when those mentors are not in great number.

Objective: Vitamin and mineral supplements are widely used for self-care of a variety of medical conditions, but little is known about the specific conditions for which they are used. This study mined consumer product reviews to determine specific ways vitamin and mineral supplements are being used therapeutically.

Design/setting: A cross-sectional analysis of user reviews for top-selling, single-ingredient vitamin and mineral products from a popular online retailer was performed to identify the most frequently appearing words associated with medical conditions.

Objective: The biomedical/behavioral sciences lag in the recruitment and advancement of students from historically underrepresented backgrounds. In 2014 the NIH created the Diversity Program Consortium (DPC), a prospective, multi-site study comprising 10 Building Infrastructure Leading to Diversity (BUILD) institutional grantees, the National Research Mentoring Network (NRMN) and a Coordination and Evaluation Center (CEC). This article describes baseline characteristics of four incoming, first-year student cohorts at the primary BUILD institutions who completed the Higher Education Research Institute, The Freshmen Survey between 2015-2019.

Diversity of backgrounds and life experiences on scientific teams is known to lead to more innovative ideas and better scientific products. However, in the United States, the percentages of individuals from underrepresented racial and ethnic groups who obtain doctoral degrees in the Sciences continue to be significantly lower than their percentages in the population. This has resulted in the need for nation-wide initiatives to remedy this inequality, and consequently produce more productive teams of scientific minds.

Xavier University of Louisiana (XULA) is the only historically Black and Catholic institution of higher education in the United States. XULA's mission focuses on "the promotion of a more just and humane society" by educating students in a diverse learning environment. Even though Xavier's reputation in the sciences attracts many of the best and brightest students in the nation, the University also continues to provide an excellent educational opportunity to many students who, due to socioeconomic disparities, lack the appropriate preparation for college.

New Caledonian representation of the cosmopolitan genus Oxyethira Eaton is reviewed, with the description of new species bringing to 26 the total for the genus on the island. The species are referred to three subgenera: Trichoglene Neboiss (11 species), Pacificotrichia Kelley (13 species) and Dampfitrichia Ulmer (one species) and one species is unplaced to subgenus. A key is provided to Oxyethira species of New Caledonia.

Polymerase chain reaction and restriction endonuclease digest are important techniques that should be included in all Biochemistry and Molecular Biology laboratory curriculums. These techniques are frequently taught at an advanced level, requiring many hours of student and faculty time. Here we present two inquiry-based experiments that are designed for introductory laboratory courses and combine both techniques.

The phylogeny of Chimarra has previously been examined using morphological characters for a smaller subset of taxa and geographical representativeness. Here molecular data from three genes (COI, CAD and POL-II) are used to reconstruct the phylogeny of the genus. The results show Chimarra to be monophyletic, and that some of the sister groups are paraphyletic.

Background: Acute incarceration of paraesophageal hernias (PEHs) requiring urgent or emergent surgery is rare. Patients are often elderly with significant comorbidities and have historically been treated with open abdominal or thoracic incisions. Our study was designed to evaluate the feasibility, safety, and efficacy of laparoscopic paraesophageal hernia repair (LPEHR) in patients with PEH and acute gastric volvulus.

Providing a project-based experience in an undergraduate biochemistry laboratory class can be complex with large class sizes and limited resources. We have designed a 6-week curriculum during which students purify and characterize the enzymes invertase and phosphatase from bakers yeast. Purification is performed in two stages via ethanol precipitation and anion exchange chromatography, and students perform both direct and coupled enzyme assays.

The New Caledonian endemic hydroptilid genus Caledonotrichia Sykora (Trichoptera) is reviewed and 6 new species are described: Caledonotrichia bifida, Caledonotrichia capensis, Caledonotrichia minuta, Caledonotrichia ouinnica, Caledonotrichia sykorai and Caledonotrichia vexilla. Together with the established species for which revised diagnoses are given, these raise to 11 the number of species known in this genus. The new species, females of 3 species, and several unusual larval cases are examined and described for further insight into relationships of this enigmatic genus.

Small ubiquitin-like modifier (SUMO) belongs to the family of ubiquitin-like proteins (Ubls) that can be reversibly conjugated to target-specific lysines on substrate proteins. Although covalently sumoylated products are readily detectible in gel-based assays, there has been little progress toward the development of robust quantitative sumoylation assay formats for the evaluation of large compound libraries. In an effort to identify inhibitors of ubiquitin carrier protein 9 (Ubc9)-dependent sumoylation, a high-throughput fluorescence polarization assay was developed, which allows detection of Lys-1201 sumoylation, corresponding to the major site of functional sumoylation within the transcriptional repressor trichorhino-phalangeal syndrome type I protein (TRPS1).

Magadacerina forcipata, new genus, new species (Trichoptera: Leptoceridae), is described from Madagascar. The monotypic genus is characterised by having the tibial spur formula 2,2,2; wings with sessile bifurcation of M; genitalia with preanal appendages fused with segment IX and greatly produced posterad, and a tergum X with an anteriorly extended ventral base articulating with a sclerotised spine-like process of the phallic shield. The new genus is most closely related to Blyzophilus in the tribe Blyzophilini.
