Certain clinical pelvic examination (PE) teaching methods have been critiqued for prioritising student learning over patient autonomy and for not accurately representing diverse patient communities. As such, patient-centred and culturally competent approaches to the PE may need further emphasis in the medical curriculum-in particular, in content delivered to students before patient interaction. Classroom materials serve as students' first exposure to the sensitive procedure. This research explores how patients are represented in these materials.

A situational analysis was conducted on 10 purposively sampled PE learning materials for the 2019/20 academic year from five undergraduate medical schools in Canada. Situational analysis focuses on analysing discourse but is epistemically aligned with post-structuralism (most notably Foucault's theories involving discursive power) and allows for specific consideration of 'silences' in the data. Collected data were analysed using cartographic approaches according ttent approaches to the procedure that (i) may not be covered in other parts of the PE curriculum and (ii) can reduce known health disparities.

Depictions contained in these materials may be perpetuating stereotypes and biases in medicine and may be working to maintain teaching practices that cause harm to patients (standardised and regular) who students interact with in both clinical and educational settings. Efforts may be needed to improve classroom materials on the PE so that they more adequately centre patients and provide opportunities to discuss culturally competent approaches to the procedure that (i) may not be covered in other parts of the PE curriculum and (ii) can reduce known health disparities.

Propionate is widely used as a preservative in the food and animal feed industries. Propionate is currently produced by petrochemical processes, and fermentative production of propionate remains challenging.

In this study, a synthetic propionate pathway was constructed in the budding yeast Saccharomyces cerevisiae, for propionate production under aerobic conditions. Through expression of tdcB and aldH from Escherichia coli and kivD from Lactococcus lactis, L-threonine was converted to propionate via 2-ketobutyrate and propionaldehyde. The resulting yeast aerobically produced 0.21 g L

propionate from glucose in a shake flask. Subsequent overexpression of pathway genes and elimination of competing pathways increased propionate production to 0.37 g L

. To further increase propionate production, carbon flux was pulled into the propionate pathway by weakened expression of pyruvate kinase (PYK1), together with overexpression of phosphoenolpyruvate carboxylase (ppc). The final propionate production reached 1.05 g L

during fed-batch fermentation in a fermenter.

In this work, a yeast cell factory was constructed using synthetic biology and metabolic engineering strategies to enable propionate production under aerobic conditions. Our study demonstrates engineered S. cerevisiae as a promising alternative for the production of propionate and its derivatives.

A DSSC with a fast ion conducting solid polymer electrolyte is required for the arid atmosphere of Gulf countries. In this work, a new matrix, poly(ethylene oxide)-tetramethyl succinonitrile blend to synthesize a blend-LiI-I2 solid polymer electrolyte for the DSSC application has been proposed. The tetramethyl succinonitrile is a member of plastic crystal with a solid-solid phase transition temperature (Tpc ) of ≈71 °C and melting temperature (Tm ) of ≈170.5 °C. Its molar fraction, 0.1-0.15 is sufficient enough for synthesizing a polymer electrolyte with electrical conductivity of >10-4 S cm-1 at room temperature. This electrolyte shows Vogel-Tamman-Fulcher type behavior with a low value (≈0.083 eV) of pseudo-activation energy for easy ion transport. The results of Fourier-transform infrared spectroscopy, X-ray diffractometry, and differential scanning calorimetry studies reveal the plasticizing effect of tetramethyl succinonitrile to form an amorphous phase. This electrolyte results in a ≈661% gain in short-circuit current density and thereby a ≈552% gain in the cell efficiency (≈3.5%) with respect to the DSSC prepared with the tetramethyl succinonitrile-free electrolyte.We performed pharyngolaryngectomy with thoracoscopic esophagectomy via the left thoracic approach and reconstruction of the elongated gastric conduit with microvascular anastomosis for an 83-year-old male patient with esophageal cancer and right aortic arch. For such cases, a surgical approach via the left thoracic cavity is rational, and cases of pharyngolaryngectomy with thoracoscopic esophagectomy require a long reconstruction organ. Also, in cases of right aortic arch, a longer reconstruction route is made to avoid Kommerell's diverticulum. The patient had laryngeal cancer and was diagnosed with cervical esophageal cancer and preoperative computed tomography revealed right aortic arch. There were no complications after surgery, and food intake was good. Pharyngolaryngectomy with thoracoscopic esophagectomy via the left thoracic approach and reconstruction of the elongated gastric conduit with microvascular anastomosis is suggested to be a safe and feasible technique for cases of cervical esophageal cancer with right aortic arch.

Negative symptoms (NS) severely affect daily functioning already at the psychosis onset. However, most studies investigating beneficial effects of specific treatments for NS mainly included individuals with prolonged psychotic disorders. Furthermore, evidence on psychosocial rehabilitation for NS in early psychosis is still relatively poor. SAR405 manufacturer The aims of this study therefore were (A) to longitudinally examine NS stability in people with first episode psychosis (FEP) along a 2-year follow-up period, and (B) to overtime explore any relevant association of NS levels with the specific intervention components of an 'early intervention in psychosis' (EIP) protocol during the follow-up.

At baseline, 266 FEP subjects (aged 12-35 years) completed the positive and negative syndrome scale (PANSS). Multiple linear regression analyses were then performed.

Along the follow-up, FEP participants had a relevant improvement in NS levels. This was specifically predicted by the total number of case management sessions offered within our 2-year EIP protocol, as well as by shorter duration of untreated psychosis at entry and by longitudinal reduction in PANSS depressive and positive symptom dimension levels. No association with antipsychotic medication was found.

NS are clinically relevant in FEP, already at the recruitment time in specialized EIP services. However, their severity appears to improve over time together with the delivery of patient-tailored, integrated EIP case management.

We address this problem of trade-offs by extending a recently proposed formal interpretation of the precautionary principle (PP) within a lexical utility framework and using it to prove results about which distribution of resources maximizes lexical utility when several catastrophic risks exist, given different assumptions. We also explain how our lexical utility interpretation of PP can recommend balanced distributions of resources between disaster prevention and other concerns.

Cutibacterium acnes is one of the common multifactorial causes that play an important role in the pathophysiology of acne vulgaris. We aimed to develop novel antimicrobial peptides for reduction of the hypercolonization.

Six cationic peptides were derived by de novo designation. The antimicrobial and cytotoxic activities of peptides were investigated. The peptide conformation was determined by circular dichroism spectrometry. The antimicrobial effects of peptides were evaluated using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and DNA-binding ability assay.

Among designed peptides, WSKK11 and WSRR11 were effective antimicrobials against C. acnes at MICs of 128 and 64 mg/L, respectively. The MICs of WSKK11 against Staphylococcus epidermidis, Staphylococcus aureus and Candida albicans were 8, 8 and 32 mg/L, while those of WSRR11 were 64, 32 and 32 mg/L, respectively. WSKK11 and WSRR11 were less toxic to human erythrocytes (<2%) and not toxic to macrophages, keratinocytes and fibroblasts up to 512 mg/L. WSKK11 and WSRR11 mostly revealed the conformation of the undefined or random coil structures under mimicked environmental conditions. The peptides affected cell surfaces and cell membranes of C. acnes as well as possibly translocating through the cell membrane, observed by a combination of SEM and TEM, respectively. WSKK11 and WSRR11 had the ability to bind bacterial DNA.

The two novel antimicrobial peptides WSKK11 and WSRR11 are members of a new class of antimicrobial agents that could deal with acne problems. Therefore, the antimicrobial peptides may be promising novel active agents for dermatological, beauty and cosmeceutical applications.

The complexity of people's social lives may constitute the dominating factor in the vibrancy of many individuals' environment. The neural substrates linked to social cognition thus appear especially susceptible when people endure periods of social isolation here, we zoom in on the systematic inter-relationships between two such neural substrates, the allocortical hippocampus (HC) and the neocortical default network (DN). Previous human social neuroscience studies have focused on the DN, while HC subfields have been studied in most detail in rodents and monkeys. To bring into contact these two separate research streams, we directly quantified how DN subregions are coherently co-expressed with specific HC subfields in the context of social isolation. A two-pronged decomposition of structural brain scans from ∼40 000 UK Biobank participants linked lack of social support to mostly lateral subregions in the DN patterns. This lateral DN association co-occurred with HC patterns that implicated especially subiculum, presubiculum, CA2, CA3 and dentate gyrus.
