Evaluation of Efficacy of 2 Extended-release Bupivacaine Products in a Porcine Model of Incisional Pain.

Extended-release (ER) local anesthetics are often incorporated in multi-modal analgesia or as an alternative when the effect of systemic analgesics may confound research. In this study, we compared the analgesic efficacy of 2 ER bupivacaine anesthetics with different ER mechanisms, a slow-release bupivacaine-meloxicam polymer (BMP) and a sucrose acetate isobutyrate bupivacaine (SABER-B) system. We used a full-thickness unilateral skin incision porcine model to evaluate the efficacy of these 2 ER bupivacaine analgesics.

Effects of Isoflurane Anesthesia on C57BL/6J Pups after Cervical Dislocation of Dams.

Inhalant anesthesia is routinely used for cesarian section in many animal species, allowing the safe delivery of neonates and smooth recovery of dams. However, in mice, inhalant anesthesia in cesarean section may be avoided due to fear of negative health effects on retrieved pups. This study compared the effects of isoflurane anesthesia on pups after cervical dislocation of conscious and anesthetized dams.

Comparison of Systemic Extended-release Buprenorphine and Local Extended-release Bupivacaine-Meloxicam as Analgesics for Laparotomy in Mice.

Extended-release (ER) local anesthetics can be used in multi-modal analgesia or in situations in which systemic analgesics may alter animal physiology and thus introduce interpretational confounds. In this study, we compared the analgesic efficacy of an ER buprenorphine formulation with that of a synergistic combination of ER bupivacaine and meloxicam. Female and male CD1 mice were randomly assigned to receive subcutaneous buprenorphine (3.

Addressing the mental health needs of learners and nonlearners in an academic medical center during COVID-19.

The coronavirus disease (COVID-19) has impacted life for people throughout the world, especially for those in health care who experience unique stressors. To support the psychological needs of staff, faculty, and learners at a biomedical sciences university, faculty at Baylor College of Medicine created a mental health and wellness support program consisting of multiple behavioral health care pathways, including phone support, a self-guided mental health app, a coping skills group, and individual therapy services. The authors present this program as a model for academic institutions to support the well-being of faculty, staff, and learners.

Influence of PCR cycle number on 16S rRNA gene amplicon sequencing of low biomass samples.

The objective of this study was to evaluate the effects of increased PCR cycle number on sequencing results from samples with low microbial biomass, including bovine milk, and murine pelage and blood. We hypothesized that subjecting DNA from such samples to higher PCR cycle numbers would increase 16S rRNA sequencing coverage. DNA was extracted from matched samples of each type and multiple PCR cycle numbers were evaluated to generate a total of 96 libraries from 24 milk samples, 46 libraries from 23 pelage samples, and 170 libraries from 85 blood samples.

Roles of trans and cis variation in yeast intraspecies evolution of gene expression.

Both cis and trans mutations contribute to gene expression divergence within and between species. We used Saccharomyces cerevisiae as a model organism to estimate the relative contributions of cis and trans variations to the expression divergence between a laboratory (BY) and a wild (RM) strain of yeast. We examined whether genes regulated by a single transcription factor (TF; single input module, SIM genes) or genes regulated by multiple TFs (multiple input module, MIM genes) are more susceptible to trans variation.

Roles of cis- and trans-changes in the regulatory evolution of genes in the gluconeogenic pathway in yeast.

The yeast Saccharomyces cerevisiae proliferates rapidly in glucose-containing media. As glucose is getting depleted, yeast cells enter the transition from fermentative to nonfermentative metabolism, known as the diauxic shift, which is associated with major changes in gene expression. To understand the expression evolution of genes involved in the diauxic shift and in nonfermentative metabolism within species, a laboratory strain (BY), a wild strain (RM), and a clinical isolate (YJM) were used in this study.

Expression evolution in yeast genes of single-input modules is mainly due to changes in trans-acting factors.

Both cis- and trans-regulatory mutations contribute to gene expression divergence within and between species. To estimate their relative contributions, we examined two yeast strains, BY (a laboratory strain) and RM (a wild strain), for their gene-expression divergence by microarray. Using these data and published ChIP-chip data, we obtained a set of single-regulator-regulated genes that showed expression divergence between BY and RM.

How do graduate student therapists incorporate diversity factors in case conceptualization?

Researchers interviewed 17 psychotherapists in training in an analogue study of psychotherapists' use of broadly defined diversity factors in conceptualizing clients and cases. Each therapist watched two 5-minute staged videotapes of clients who varied along dimensions of race and ethnicity, age, and gender. Each acting client described problems in an initial psychotherapy interview, and then participant therapists responded to questions.
