A series of achiral indole analogues of the selective sirtuin inhibitor EX-527 (a racemic, substituted 1,2,3,4 tetrahydrocarbazole) was designed to stabilize the bioactive conformation, and synthesized. These new indoles were evaluated against the isolated sirtuin enzymes SIRT1 and SIRT2, and against a panel of nine human cell lines. Structure-activity relationship studies demonstrated the influence of the substituent at position 3 of the indole. The most potent SIRT1 inhibitor 3h, bearing an isopropyl substituent, was as potent as EX-527, and more selective for SIRT1 over SIRT2. Compound 3g, bearing a benzyl substituent, inhibited both sirtuins at micromolar concentration and was more cytotoxic than EX-527 on several cancer cell lines.

Displacement of oil droplets receding from solid surfaces in aqueous solutions plays a critical role in many household activities and industrial operations. Surfactants are often involved in these activities to control the displacement process. We hypothesize that the influence of surfactants on the displacement process of oil is highly dependent on the type and dosage of surfactants, with the mechanisms being elucidated by the analysis using appropriate dynamic wetting models.

We systematically investigated the spontaneous displacement of a high viscosity oil on curved hydrophilic glass surfaces in aqueous solutions of anionic sodium dodecylbenzene sulfonate, cationic hexadecyl trimethyl ammonium bromide, and nonionic Triton

X-100 over a wide range of concentrations.

The rather different oil displacement behaviors were observed with different surfactant additions. The displacement dynamics of the receding oil droplet was found to be inhibited by surfactant additions and followed two distinct models qynamics.

Hip fracture is one of the most common injuries in adults and can be a life changing experience for most. Many patients are ill-prepared for the changes in their normal daily activity that often occur in the following months after surgery. Community rehabilitation services vary, as management often focuses on acute over community services. This can impact on the patient's experience post hip fracture.

The aim of this review was to understand and examine patients' perspective, views and experiences of physiotherapy rehabilitation in the community after hip fracture surgery, to improve future clinical practice for this population.

A qualitative thematic synthesis was undertaken to investigate the aim. A content thematic analysis approach was used to analyse the qualitative data.

A systematic search was carried out of the following databases CINAHL, PEDro, PubMed, Whiley Online, AMED & CINAHL. Further searches were performed in Google Scholar and backwards citation was used to search within included ort the need for the patient perspective and experience to be considered in the improvement of hip fracture care pathways regarding rehabilitation in the community setting after hip fracture. This can help identify key areas of improvement in rehabilitation to enhance and improve the patient journey after hip fracture. Systematic Review Registration Number PROSPERO CRD42018095434.

To investigate the distribution of patella skin temperature (Tsk) measurements and to explore the presence of temperature subgroups in patellofemoral pain (PFP) patients.

Cross-sectional observational study design.

One dataset of 58 healthy participants and 232 PFP patients from three different datasets.

Patella skin temperature, measured by physiotherapists using a low cost hand held digital thermometer. Selumetinib The distribution of patella skin temperature was assessed and compared across datasets. To objectively determine the clinically meaningful number of subgroups, we used the average silhouette method. Finite mixture models were then used to examine the presence of PFP temperature subgroups. Receiver operating characteristic curves were used to estimate optimal patella Tsk thresholds for allocation of participants into the identified subgroups.

In contrast to healthy participants, the patella skin temperature had an obvious bimodal distribution with wide dispersion present across all three PFP datasets. The fitted finite mixture model suggested three temperature subgroups (cold, normal and hot) that had been recommended by the average silhouette method with discrimination cut-off thresholds for subgroup membership based on receiver operating curve analysis of Cold=<30.0°C; Normal 30.0-35.2°C; Hot ≥35.2°C.

A low cost hand held digital thermometer appears to be a useful clinical tool to identify three PFP temperature subgroups. Further research is recommended to deepen understanding of these clinical findings and to explore the implications to different treatments.

Discrete choice experiments (DCEs) are used in healthcare to measure the relative importance that stakeholders give to different features (or attributes) of medical treatments or services. They may also help to address research questions in health professional education. Several challenges exist regarding the performance-based assessment process (PBA) employed in physiotherapy practice-based education, a process which determines students' readiness for independent practice. Evidence highlights many commonalities among these challenges, but it is unknown which factors are the most important to stakeholders. The use of DCE methodology may provide answers and help to prioritise areas for development. Thus, this study employed DCE to identify clinical educators', practice tutors and physiotherapy students' preferences for developing the PBA process in physiotherapy.

Attributes (aspects of the PBA process known to be important to stakeholders) were derived from focus group interviews conducted with three groupilitates a prioritised pathway for development of this process.Major histocompatibility complex (MHC) molecules bind peptides originated from cellular synthesis and present them at the cell surface for recognition by receptors on immune cells like T lymphocytes, natural killer (NK) cells or mast cells. Such recognition plays a crucial part in autoimmunity, anti-bacterial, anti-viral and anti-tumor responses. Human leukocyte antigen G (HLA-G) is a member of non-classical HLA class I molecules which has been studied deeply in recent years into its role in pregnancy and endometrial diseases, including endometrial tumor, endometriosis and adenomyosis, etc. Understanding the mechanism of the maintenance of pregnancy and immune escape of endometrial diseases in a HLA-G dependent way is of current interest. Perception from studies in the expression of HLA-G and possible pathways is a vital part of understanding mechanisms related to immune escape.
