Socioecological models of bystander intervention suggest that a complex decision-making process is required for a prosocial bystander to intervene, starting with intrapersonal variables of cognition and personality. This study investigates how rape myth acceptance, personality, and just world beliefs impact the frequency of positive bystander intention. The study's sample size consisted of 139 college students.

However, the translation from patterns of allele frequency change to rapid adaptation of complex traits remains unresolved. We used abdominal pigmentation in as a model phenotype to address the nature, genetic architecture, and repeatability of rapid adaptation in the field.

Mitochondria are the hubs of metabolism, crucial for energetic functions and cellular homeostasis. The mitochondrion's bacterial origin and preservation of their own genome, which encodes proteins and RNAs essential to their function, make them unique organelles.

Such applications often require forming the sheets into the final components, which is typically aided by an oil-based lubricant, followed by joining them using adhesives, which is hampered by residual lubricant. In this work, aluminum surfaces were modified with different self-assembled monolayers (SAMs), with the goal of significantly reducing the amount of lubricant while simultaneously improving friction properties, forming, and bonding performance.
View Article and Find Full Text PDFImmune checkpoint inhibitors (ICIs) have changed therapy strategies in breast cancer (BC) patients suffering from triple-negative breast cancer (TNBC). For example, in Europe the anti-programmed cell death 1 ligand 1 (PD-L1) ICI Azetolizumab is approved for adult patients with locally advanced or metastasized TNBC (mTNBC), depending on the immunohistochemical (IHC) PD-L1 expression of immune cells in the tumor area [immune cell (IC) score ≥1%); the anti-programmed cell death 1 (PD-1) ICI pembrolizumab is approved for mTNBC if PD-L1 Combined Positive Score (CPS), that is PD-L1 expression on tumor and/or immune cells, is ≥10. For early TNBC, in contrast, neoadjuvant use of pembrolizumab is approved in the United States and Europe independent from PD-L1 IHC expression.

Furthermore, to provide the differential diagnoses of the observed alterations, with special attention to the cranial osteolytic lesions. During the macro- and micromorphological examinations of KB67, the skull revealed three small, well-circumscribed, punched-out osteolytic lesions accompanied by endocranial granular impressions, abnormal blood vessel impressions, periosteal appositions, and cortical erosion.

Objectives of this process evaluation were to investigate whether the patient-centered matching guidelines (PCPM) are consistently applied in referral decision-making from an inpatient qualified withdrawal program to a level of care in aftercare, which factors affect whether patients actually receive matched aftercare according to PCPM, and whether its use is feasible and accepted by clinic staff.
Methods: The study was conducted as process evaluation within an exploratory randomized controlled trial in four German psychiatric clinics offering a 7-to-21 day qualified withdrawal program for patients suffering from alcohol dependence, and with measurements taken during detoxification treatment and six months after the initial assessment.
Single-color reflectrometry is a sensitive and robust detection method in optical biosensor applications, for example for bioanalysis. It is based on the interference of reflected monochromatic radiation and is label free. We present a novel setup for single-color reflectometry based on the patented technology of Berner et al.

The core of the device is a disposable plastic chip where an immunoassay for the determination of immunosuppressants takes place. The chip is designed in order to have ten parallel microchannels allowing the simultaneous detection of more than one analyte with replicate measurements.

Seventeen college student volunteers responded to an online survey questionnaire assessing their motivations for volunteering and how they were impacted by their experiences. Motivational functions for volunteering (values, understanding, social, career, protective, enhancement) were assessed using the Volunteer Functions Inventory.

Design: Prepost study design.
Setting: Cooking Matters for Kids programs offered by 35 organizations.
Objectives: To quantify the number and type of students failing to secure basic needs.
Participants: Students attending 22 postsecondary schools in the United States in Fall 2019.
Methods: The Adult Food Security Module and part of the #RealCollege Survey were used to measure food and housing insecurity, respectively.
Objective: This paper aims to contribute to the definition of ancient rare diseases in skeletons displaying pathologies associated with paralysis. It uses a new suite of methods, which can be applied to challenging cases of possible paralysis in archaeologically-derived human skeletal material, specifically applied to the identification of poliomyelitis.
Materials: An adult male skeleton from Roman Halbturn, Austria.
For bone preparation, several maceration techniques are available; however, gentle defleshing and soft tissue removal from bones without damaging the bone surface remains a challenge. The study aims to develop a novel, inexpensive, rapid, and resource-saving maceration technique that does not lead to bone surface changes and allows the study of signs of violence on the bone surface. Pig ribs and femurs were covered in aluminum foil and treated in the oven for 5 h at different temperatures with and without detergent.

Patients with neurofibromatosis type 1 syndrome (NF1), an autosomal dominant tumor predisposition syndrome, are at a high risk for MPNSTs, which usually develop from pre-existing benign Schwann cell tumors called plexiform neurofibromas. NF1 is characterized by loss-of-function mutations in the gene, which encode neurofibromin, a Ras GTPase activating protein (GAP) and negative regulator of RasGTP-dependent signaling.

Design: An online survey was administered. Food insecurity was assessed using the ten-item Adult Food Security Survey Module.
The prevalence of food insecurity in the USA has increased since the start of the COVID-19 pandemic; however, past studies have not examined how the food security status of college students has been impacted. The purpose of this study was to examine changes in the prevalence of food insecurity; determine the proportion of students experiencing a change in food security status; and identify characteristics associated with changes in food security status from before to during the COVID-19 pandemic among a sample of college students. We administered a cross-sectional online survey to students from a large public university in the Southeastern USA.

Design: Cross-sectional online survey.
Background: Placement matching guidelines are promising means to optimize patient-centered care and to match patients' treatment needs. Despite considerable research regarding placement matching approaches to optimize alcohol abuse treatment, findings are inconclusive.
Objectives: To investigate whether the use of patient-centered placement matching (PCPM) guidelines is more effective in reducing heavy drinking and costs 6 months after discharge from an inpatient alcohol withdrawal treatment compared to usual referral to aftercare.
Background: A number of studies have measured college student food insecurity prevalence higher than the national average; however, no multicampus regional study among students at 4-y institutions has been undertaken in the Appalachian and Southeast regions of the United States.
Objectives: The aims of this study were to determine the prevalence of food insecurity among college students in the Appalachian and Southeastern regions of the United States, and to determine the association between food-insecurity status and money expenditures, coping strategies, and academic performance among a regional sample of college students.
Methods: This regional, cross-sectional, online survey study included 13,642 college students at 10 public universities.
