The antibiotic is produced by the oral bacterium and is a member of the epidermin family of type AI lantibiotics. The antibiotic exerts its inhibitory activity by binding to the cell wall precursor lipid II, blocking cell wall synthesis, and by disrupting bacterial membranes.

Hot-Melt extrusion coupled with pressurized carbon dioxide for enhanced processability of pharmaceutical polymers and drug delivery applications - An integrated review.

Hot-melt extrusion (HME) technology is one of the primary approaches that has been implemented in recent years to overcome poor drug solubility/dissolution issues through the development of solid dispersion systems. Carbon dioxide (CO) either in supercritical (SupC) or subcritical (SubC) forms has been introduced to HME as a temporary plasticizer, reducing the operating temperature and eventually processing heat-sensitive molecules more efficiently. In this paper, a comprehensive review of CO-HME processes focused on pharmaceutical polymers and applications is presented.

Diet and physical activity in pregnancy to prevent gestational diabetes: a protocol for an individual participant data (IPD) meta-analysis on the differential effects of interventions with economic evaluation.

Introduction: Mothers with gestational diabetes mellitus (GDM) are at increased risk of pregnancy-related complications and developing type 2 diabetes after delivery. Diet and physical activity-based interventions may prevent GDM, but variations in populations, interventions and outcomes in primary trials have limited the translation of available evidence into practice. We plan to undertake an individual participant data (IPD) meta-analysis of randomised trials to assess the differential effects and cost-effectiveness of diet and physical activity-based interventions in preventing GDM and its complications.

Multidrug resistant Mannheimia haemolytica isolated from high-risk beef stocker cattle after antimicrobial metaphylaxis and treatment for bovine respiratory disease.

Antimicrobial resistance (AMR) in bacterial respiratory pathogens in high-risk stocker cattle has been poorly characterized. The objective of this study was to describe the prevalence of multidrug resistant (MDR; resistance to > 3 antimicrobial classes) respiratory pathogens in 50 conventionally managed stocker cattle over 21 days after arrival. Cattle received tildipirosin metaphylaxis on day 0 and were eligible to receive up to 3 additional antimicrobials for bovine respiratory disease (BRD): florfenicol, ceftiofur and enrofloxacin.

Construction and evaluation of type III secretion system mutants of the catfish pathogen Edwardsiella piscicida.

Catfish is the largest aquaculture industry in the United States. Edwardsiellosis is considered one of the most significant problems affecting this industry. Edwardsiella piscicida is a newly described species within the genus Edwardsiella, and it was previously classified as Edwardsiella tarda.

Covalent Structure and Bioactivity of the Type AII Lantibiotic Salivaricin A2.

Lantibiotics are a class of lanthionine-containing, ribosomally synthesized, and posttranslationally modified peptides (RiPPs) produced by Gram-positive bacteria. Salivaricin A2 belongs to the type AII lantibiotics, which are generally considered to kill Gram-positive bacteria by binding to the cell wall precursor lipid II via a conserved ring A structure. Salivaricin A2 was first reported to be isolated from a probiotic strain, K12, but the structural and bioactivity characterizations of the antibiotic have remained limited.

Online Process Phase Detection Using Multimodal Deep Learning.

We present a multimodal deep-learning structure that automatically predicts phases of the trauma resuscitation process in real-time. The system first pre-processes the audio and video streams captured by a Kinect's built-in microphone array and depth sensor. A multimodal deep learning structure then extracts video and audio features, which are later combined through a "slow fusion" model.

Oncologic Risk Stratification Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Appendiceal Carcinomatosis.

Introduction: Patients with peritoneal carcinomatosis (PC) of appendiceal origin demonstrate variable oncologic outcomes, despite aggressive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). We sought to devise a prognostic risk stratification system for oncologic outcomes following CRS-HIPEC.

Methods: A total of 197 patients undergoing CRS-HIPEC for the treatment of appendiceal PC were reviewed from a prospective database.

Characterization of a novel two-component regulatory system, HptRS, the regulator for the hexose phosphate transport system in Staphylococcus aureus.

Hexose phosphate is an important carbon source within the cytoplasm of host cells. Bacterial pathogens that invade, survive, and multiply within various host epithelial cells exploit hexose phosphates from the host cytoplasm through the hexose phosphate transport (HPT) system to gain energy and synthesize cellular components. In Escherichia coli, the HPT system consists of a two-component regulatory system (UhpAB) and a phosphate sensor protein (UhpC) that tightly regulate expression of a hexose phosphate transporter (UhpT).

Effects of jazz on postoperative pain and stress in patients undergoing elective hysterectomy.

Context: Anesthesiologists use various medications to provide surgical patients with pain relief in the postoperative period. Other modalities, such as music, could be used in conjunction with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease pain and lower heart rate and blood pressure. Our hypothesis was that patients listening to jazz in a postanesthesia care unit (PACU) would have lower heart rates and blood pressures and reduced pain and anxiety.

Lactococcosis in Silver Carp.

An adult Silver Carp Hypophthalmichthys molitrix with a focally extensive skin lesion near the caudal peduncle and mild iridial hemorrhage was submitted to the Aquatic Research and Diagnostic Laboratory (ARDL) in Stoneville, Mississippi, as part of a fish kill investigation. Touch impressions of this musculoskeletal lesion revealed small cocci (∼1 μm) in pairs or chains within an inflammatory milieu. A pure Gram-positive cocci isolate was obtained from the brain, while cultures of the kidney and muscle yielded multiple bacterial colony types, including the Gram-positive cocci seen in the brain.

Extensive cytoreductive surgery for appendiceal carcinomatosis: morbidity, mortality, and survival.

Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) are frequently used to treat appendiceal carcinomatosis. Some patients require multivisceral resection because of the volume of disease. It is unclear whether extent of CRS impacts survival in appendiceal carcinomatosis.

A rationally designed A34R mutant oncolytic poxvirus: improved efficacy in peritoneal carcinomatosis.

Oncolytic poxviruses have demonstrated initial promising results in patients with cancer in clinical trials, yet further improvements are needed. It has been shown that a single point mutation in the A34R gene resulted in the production of more total progeny virus and more extracellular enveloped virus (EEV), a form that can be immune-evasive and with enhanced spread. We have genetically engineered a new oncolytic poxvirus (designated vA34R) by incorporating this mutated A34R gene into a viral backbone (vvDD) which was designed for tumor-selective replication.

Significance of serum tumor marker levels in peritoneal carcinomatosis of appendiceal origin.

Background: The significance of tumor markers in patients with appendiceal carcinomatosis is poorly defined. We determined preoperative and postoperative tumor marker levels in patients undergoing cytoreductive surgery (CRS) and heated intraperitoneal chemoperfusion (HIPEC) and examined their association with clinicopathologic features and survival.

Methods: A total of 176 patients undergoing attempted CRS/HIPEC for appendiceal carcinomatosis had at least 1 tumor marker measured.
