The US population is becoming more racially and ethnically diverse. Research suggests that cultural diversity within organizations can increase team potency and performance, yet this theory has not been explored in the field of surgery. Furthermore, when surveyed, patients express a desire for their care provider to mirror their own race and ethnicity. In the present study, we hypothesize that there is a positive correlation between a high ranking by the US News and World Report for gastroenterology and gastrointestinal (GI) surgery and greater racial, ethnic, and gender diversity among the physicians and surgeons.

We used the 2019 US News and World Report rankings for best hospitals by specialty to categorize gastroenterology and GI surgery departments into 2 groups 1-50 and 51-100. Hospital websites of these top 100 were viewed to determine if racial diversity and inclusion were highlighted in the hospitals' core values or mission statements. To determine the rates of diversity within departments, Betafimportance of having a culturally diverse staff, yet their care providers may not adequately reflect the populations they serve. UPF 1069 in vivo Further work is needed to prospectively track diversity rates over time and correlate these changes with measurable outcomes.In the secretome of Phanerochaete chrysosporium, a white-rot fungus serving as a model organism to elucidate lignocellulose deconstruction, the copper containing metalloprotein glyoxal oxidase (GLOX) is potentially involved in the crucial production of hydrogen peroxide to fuel and initiate oxidative biomass degradation by lignin-degrading peroxidases. Its ability to oxidize a variety of aldehydes and α-hydroxy carbonyls with the concomitant reduction of dioxygen to hydrogen peroxide has attracted attention for its application as green biocatalyst in different industrial fields. Here we report and compare two efficient processes for the heterologous production of GLOX from P. chrysosporium using the well-established methanolytic yeast Pichia pastoris and the filamentous fungus Trichoderma reesei as expression hosts with subsequent purification by anion exchange and hydrophobic interaction chromatography. Both processes were shown to be suitable for the production of the target protein at high levels. GLOX produced in T. reesei carries mainly Man5 glycosylation while the enzyme produced in P. pastoris exhibits the typical high-mannose type N-glycosylation. The enzyme expressed in P. pastoris showed slightly higher specific activities which correlates with the higher copper loading of 65.5 % compared to 51.9 % for the protein from T. reesei. The pH optimum for both recombinant proteins was 6.0, however, GLOX activity was found to be highly affected by different buffer species. Both enzymes showed very similar substrate affinities and turnover numbers with the highest catalytic efficiency observed for methylglyoxal. GLOX from both expression hosts is therefore a suitable enzyme for further mechanistic characterization and application studies.Filamentous fungi belonging to the Aspergillus genus are one of the most favored microorganisms for industrial enzyme production because they can secrete large amounts of proteins into the culture medium. α-Amylase, an enzyme produced by Aspergillus species, is important for food and industrial applications. The production of α-amylase is induced by starch, mainly obtained from the edible biomass; however, the increasing demand for foods is limiting the application of the latter. Therefore, it is expected that using the non-edible biomass, such as rice straw, could improve the competition for industrial application starch containing resources. The transcription factor AmyR activates the transcription of amylolytic enzyme genes, while the transcription factor XlnR activates the transcription of xylanolytic enzyme genes in response to xylose. In this study, we aimed to construct an artificial AmyRXlnR transcription factor (AXTF) by replacing the DNA-binding domain (1-159 amino acids) of XlnR with that (1-68 aa)dible xylan-containing hemicellulosic biomass by transforming it with the chimeric transcription factor AXTF. Furthermore, the use of genes encoding engineered transcription factors is advantageous because introducing such genes into an industrial Aspergillus strain has similar simultaneous effects on multiple amylase genes controlled by AmyR.Alcohol oxidase (AOx) from P. pastoris has potential applications in the production of carbonyl compounds and for the detection and quantification of alcohols. However, AOx's poor stability and low activity have hindered its practical application. There are two fractions of AOx in P. pastoris with different thermal stability. High hydrostatic pressure (HHP) increased the activity of the labile (L) + resistant (R) combined fractions but not of the R fraction alone. The activity of the L + R fractions increased 2.4-fold at 160 MPa and 30 °C compared to the activity at 0.1 MPa. At higher temperatures, the increase in activity with pressure was greater due to the combined stabilization and activation effects. The reaction rate of the R fraction at 50 °C was 17.9 ± 3.6 or 17.7 ± 0.8 μM min-1 at 80 or 160 MPa, respectively, and was not significantly different from the activity of the L + R fractions under the same conditions (18.4 ± 2.7 μM min-1). The activation energy of the R fraction was not significantly different between 80 MPa (41.5 ± 10.5 kJ mol-1) and 160 MPa (43.8 ± 7.8 kJ mol-1). The combined increase in the stability of the R fraction at HHP enables the use of the enzyme at 50 °C with little loss of activity and an increased catalytic rate.The objective of this project was to ferment lactose and whey to ethanol in one-step process. Models of cell factory of non-engineered S.cerevisiae have been proposed to ferment lactose. The cell factory of non-engineered S. cerevisiae/SG-lactase was prepared by the addition, of a starch gel solution containing lactase on non-engineered S. cerevisiae, and freeze drying of it. The 2-layer non engineered S.cerevisiae-TC/SG-lactase factory was prepared by immobilizing S. cerevisiae on the internal layer of tubular cellulose (TC), and the lactase enzyme was contained in the upper layer of starch gel (SG) covering cells of S. cerevisiae. Using such cell factory for the fermentation of lactose, alcohol yield of 23-32 mL/L at lactose conversion of 71-100%. The improvement in alcohol yield by cell factory versus co-immobilization of lactase enzyme and S. cerevisiae on alginates, was found in the range of 28-78%. Likewise, the cell factories are more effective than engineered S. cerevisiae. The fermentation of whey instead of lactose resulted in a significant reduction of the fermentation time.
