Copper Is Accumulated as Copper Sulfide Particles, and Not Bound to Glutathione, Phytochelatins or Metallothioneins, in the Marine Alga (Chlorophyta).

To analyze the mechanism of copper accumulation in the marine alga , it was cultivated with 10 μM of copper, with 10 μM of copper and increasing concentrations of a sulfide donor (NaHS) for 0 to 7 days, and with 10 μM of copper and a concentration of the sulfide acceptor (hypotaurine) for 5 days. The level of intracellular copper was determined as well as the level of glutathione (GSH) and phytochelatins (PCs) and the expression of metallothioneins (UcMTs). The level of intracellular copper in the algae treated with copper increased at day 1, slightly increased until day 5 and remained unchanged until day 7.

Decreasing Intraoperative Skin Damage in Prone-Position Surgeries.

Objective: To determine if subepidermal moisture (SEM) measures help detect and prevent intraoperative acquired pressure injuries (IAPIs) for prone-position surgery.

Methods: In this clinical trial of patients (n = 39 preintervention, n = 48 intervention, 100 historical control) undergoing prone-position surgery, researchers examined the use of multidimensionally flexible silicone foam (MFSF) dressings applied preoperatively to patients' face, chest, and iliac crests. Visual skin assessments and SEM measures were obtained preoperatively, postoperatively, and daily for up to 5 days or until discharge.

Parallel evolution of integrated craniofacial traits in trophic specialist pupfishes.

Populations may adapt to similar environments via parallel or non-parallel genetic changes, but the frequency of these alternative mechanisms and underlying contributing factors are still poorly understood outside model systems. We used QTL mapping to investigate the genetic basis of highly divergent craniofacial traits between the scale-eater () and molluscivore () pupfish adapting to two different hypersaline lake environments on San Salvador Island, Bahamas. We lab-reared F2 scale-eater x molluscivore intercrosses from two different lake populations, estimated linkage maps, scanned for significant QTL for 29 skeletal and craniofacial traits, female mate preference, and sex.

"The Wild West:" Nurse Experiences of Responding to the 2017 Las Vegas Mass Shooting.

Objective: The purpose of this study was to explore the experiences of nurses who responded to a public mass shooting in 2017.

Methods: This qualitative study was conducted with a sample of nurses who responded to a mass shooting, recruited purposively from a hospital in Las Vegas, Nevada. Intensive interviews were conducted with a total of 7 nurses, audio-recorded and transcribed for thematic analysis.

Academic Health Centers and Humanitarian Crises: One Health System's Response to Unaccompanied Children at the Border.

University of California Health (UCH) provided a system-wide, rapid response to the humanitarian crisis of unaccompanied children crossing the southern U.S. border in the midst of the COVID-19 pandemic in 2021.

Transcriptomic analyses reveal increased expression of dioxygenases, monooxygenases, and other metabolizing enzymes involved in anthracene degradation in the marine alga .

To analyze the mechanisms involved in anthracene (ANT) degradation in the marine alga , total RNA was obtained from the alga cultivated without ANT and with 5 μM of ANT for 24 h, and transcriptomic analyses were performed. A transcriptome was assembled, transcripts differentially expressed were selected, and those overexpressed were identified. Overexpressed transcripts potentially involved in ANT degradation were: one aromatic ring dioxygenase, three 2-oxoglutarate Fe (II) dioxygenases (2-OGDOs), and three dienelactone hydrolases that may account for anthraquinone, phthalic anhydride, salicylic acid, and phthalic acid production (pathway 1).

Investigating a Substance Abuse Screening in a Trauma Setting.

Introduction: Drug and alcohol consumption are often associated with trauma-related injuries. Various studies have been conducted which have shown the benefits of screening and brief intervention (SBI) tools for alcohol consumption. Despite their success, there are few SBI tools utilized for substance use and minimal reports of computerized versions.

Prenatal Screening for Thrombophilias: Indications and Controversies, an Update.

Pregnancy is associated with increased clotting potential and decreased fibrinolysis. Women with thrombophilias have an increased risk of venous thromboembolism during pregnancy. At least 50% of cases of venous thromboembolism in pregnant women are associated with an inherited or acquired thrombophilia.

Correlation of serum fructosamine and recurrent pregnancy loss: Case-control study.

Aim: Pre-gestational diabetes is associated with an elevated risk of pregnancy loss, but it is unclear whether subclinical glucose intolerance is associated with pregnancy loss, especially recurrent pregnancy loss (RPL). The aim of this study was therefore to compare maternal serum fructosamine (a marker of glycemic control) in patients with and without RPL.

Methods: A case-control study was carried out of 117 women with unexplained RPL, defined as two or more pregnancy losses with no more than one live birth, and 117 age-matched controls with at least one full-term uncomplicated pregnancy and no more than one pregnancy loss.

An extension of the theory of planned behavior to predict pedestrians' violating crossing behavior using structural equation modeling.

This paper aimed to examine pedestrians' self-reported violating crossing behavior intentions by applying the theory of planned behavior (TPB). We studied the behavior intentions regarding instrumental attitude, subjective norm, perceived behavioral control, the three basic components of TPB, and extended the theory by adding new factors including descriptive norm, perceived risk and conformity tendency to evaluate their respective impacts on pedestrians' behavior intentions. A questionnaire presented with a scenario that pedestrians crossed the road violating the pedestrian lights at an intersection was designed, and the survey was conducted in Dalian, China.

Cervical length screening: a randomized trial assessing the impact on visit length and patient attitudes.

Objectives: The purpose of this study was to quantify the time required for transvaginal cervical length measurements during a second-trimester anatomy scan and to evaluate patient attitudes regarding cervical length assessment.

Methods: Consenting women were randomly assigned to one of the following: (1) standard arm-cervix visualized, no prespecified cervical length measurement; (2) sequential arm-3 transabdominal cervical length measurements obtained, transvaginal sonography performed if images were inadequate or if any measurement was 3 cm or less; and (3) screening transvaginal sonography arm-3 transvaginal cervical length measurements obtained. Times were recorded for the entire examination and cervical length evaluation.

Celiac disease serum markers and recurrent pregnancy loss.

Celiac disease has been associated with numerous unfavorable health outcomes, including pregnancy complications such as infertility, preterm birth, and preeclampsia. However, the association between celiac disease and recurrent pregnancy loss (RPL) remains uncertain. Our purpose was to compare serum markers of celiac disease in women with and without RPL.

Cesarean delivery on maternal request: a western North Carolina perspective.

Cesarean delivery on maternal request (CDMR), a primary cesarean without medical indication for a singleton, term pregnancy, has been identified by physicians as one factor in the increasing rate of cesarean delivery despite nationwide efforts to the contrary. The purpose of this project was to better understand women's preferences and motivations for their desired mode of delivery. A 62-item survey was administered to pregnant women asking for their delivery preference, their reasons, sources of information, feelings about this pregnancy, and opinions about delivery options.
