Synthesis of Cyclic Oligomers of Polyether Ketone Ketone (PEKK) for Ring-Opening Polymerisation (ROP) Applications.

Entropy-Driven Ring-Opening Polymerisation represents an attractive mechanism to produce high-performance polymeric materials as it can be performed using neat, low-viscosity precursors and without the production of by-products or release of volatiles. Macrocyclic oligomers (MCOs) of polyether ketone ketone (PEKK) were synthesised and investigated as an method of forming this high-performance thermoplastic. Cyclic oligomers were successfully synthesised by pseudo-high dilution methods, and the reaction conditions were optimised through careful addition of starting materials and carbonate base selection.

A Narrative Review on the Neurocognitive Profiles in Eating Disorders and Higher Weight Individuals: Insights for Targeted Interventions.

: Recent research has increasingly explored the cognitive processes underlying eating disorders (EDs), including anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified feeding or eating disorders (OSFEDs), and individuals with higher weight (HW). This critical narrative review focuses on neurocognitive findings derived from mainly experimental tasks to provide a detailed understanding of cognitive functioning across these groups. Where experimental data are lacking, we draw on self-report measures and neuroimaging findings to offer supplementary insights.

Cytotoxicity and Antimicrobial Efficacy of Fe-, Co-, and Mn-Doped ZnO Nanoparticles.

Zinc oxide nanoparticles (ZnO NPs) are one of the most widely used nanoparticulate materials due to their antimicrobial properties. However, the current use of ZnO NPs is hindered by their potential cytotoxicity concerns, which are likely attributed to the generation of reactive oxygen species (ROS) and the dissolution of particles to ionic zinc. To reduce the cytotoxicity of ZnO NPs, transitional metals are introduced into ZnO lattices to modulate the ROS production and NP dissolution.

Testing Concrete Sewer Maintenance Holes Using an Angular Modulated Penetrometer.

Around the world, a significant proportion of sewers and sewer maintenance holes are constructed from concrete. Unfortunately, one major problem with concrete sewer infrastructure is corrosion caused by biogenic hydrogen sulphide, which causes major issues for concrete structural integrity. Furthermore, concrete may be significantly corroded and softened but still pass a visual inspection.

TLR7 Promotes Acute Inflammatory-Driven Lung Dysfunction in Influenza-Infected Mice but Prevents Late Airway Hyperresponsiveness.

Severe lower respiratory tract disease following influenza A virus (IAV) infection is characterized by excessive inflammation and lung tissue damage, and this can impair lung function. The effect of toll-like receptor 7 (TLR7), which detects viral RNA to initiate antiviral and proinflammatory responses to IAV, on lung function during peak infection and in the resolution phase is not fully understood. Using wild-type (WT) C57BL/6 and TLR7 knockout (TLR7 KO) mice, we found that IAV infection induced airway dysfunction in both genotypes, although in TLR7 KO mice, this dysfunction manifested later, did not affect lung tissue elastance and damping, and was associated with a different immune phenotype.

TRAPPopathies: Severe Multisystem Disorders Caused by Variants in Genes of the Transport Protein Particle (TRAPP) Complexes.

The TRAPP (TRAnsport Protein Particle) protein complex is a multi-subunit complex involved in vesicular transport between intracellular compartments. The TRAPP complex plays an important role in endoplasmic reticulum-to-Golgi and Golgi-to-plasma membrane transport, as well as autophagy. TRAPP complexes comprise a core complex, TRAPPI, and the association of peripheral protein subunits to make two complexes, known as TRAPPII and TRAPPIII, which act as Guanine Nucleotide Exchange Factors (GEFs) of Rab11 and Rab1, respectively.

Exploring Reverse Sural Flap Necrosis in Lupus-like Syndrome: Challenges and Strategies in Lower Limb Reconstruction-A Case Presentation.

Soft tissue reconstruction in the lower limbs presents a significant challenge, particularly when addressing defects in the distal third of the leg, ankle, and foot. The reverse sural flap reliant on the perforating branches of the peroneal artery has emerged as a versatile option, offering a solution for patients for whom microsurgical techniques are not feasible. Despite its advantages, the procedure carries inherent risks, especially in populations with underlying conditions, such as venous insufficiency, cardiovascular disease, and diabetes, as well as in elderly patients, where the likelihood of flap necrosis is elevated.

Advanced Dynamic Centre of Pressure Diagnostics with Smart Insoles: Comparison of Diabetic and Healthy Persons for Diagnosing Diabetic Peripheral Neuropathy.

Although diabetic polyneuropathy (DPN) has a very high prevalence among people with diabetes, gait analysis using cyclograms is very limited, and cyclogram research, in general, is limited to standard measures available in software packages. In this study, cyclograms (movements of the centre of pressure, COP, on and between the plantar surfaces) of diabetics and healthy individuals recorded with a smart insole were compared in terms of geometry and balance index, BI. The latter was calculated as the summed product of standard deviations of cyclogram markers, i.

An Attachment-Based Family Therapy for Anxiety and Depression in Children: A Mixed-Methods Evaluation of BEST-Foundations.

Background/objectives: Parent-child attachment and family relationships have been identified as risk factors for childhood internalising symptoms such as anxiety and depressive symptoms. This mixed-methods evaluation examined the feasibility of a recently developed attachment-based family intervention, Behaviour Exchange Systems Therapy-Foundations (BEST-F), delivering 16 h of therapy over 8 weeks to treat internalising symptoms in children aged between 3 and 11 years.

Methods: The quantitative outcomes of this uncontrolled study of 17 families were based on the parent-reported Child Behaviour Checklist (CBCL) measure, completed at four-timepoints (baseline, pre-, post-intervention, and follow-up), while qualitative data were collected from interviews with participants at follow-up.

The Role of Caregivers in Promoting Connectedness in Youth with Mental Health Concerns.

Mental health concerns among youth represent a critical global public health issue. Research has found that youth with mental health concerns are often reliant on their caregivers while being isolated from peers. Guided by the recovery model of mental health care, this study investigates the often-overlooked role of caregivers in fostering 'connectedness' in youth; Methods: Semi-structured interviews were conducted with nine caregivers of youth with mental health issue; Results: Thematic analysis underscored three tasks in the role of caregivers in promoting connectedness in youth: (a) understanding the nature and quality of social networks, (b) supporting readiness to engage in social relationships, and (c) promoting their youth's social problem solving and self-efficacy; Discussion: These tasks highlight the complex dialectics faced by caregivers in supporting youth recovery.

The Effect of Increasing the Body's Core Temperature and Improving Blood Flow by Using Far-Infrared Rays Emitted from Functional Loess Bio-Balls.

Background: Low-energy far-infrared rays (FIRs) are widely used in the treatment of wounds, lymphedema, and various vascular diseases, and various types of products that emit infrared rays are being used at home for patients with blood flow-related diseases without experimental evidence.

Methods: Blood flow and epidermal temperature were measured while applying conductive heat and FIRs via an electric mat (non-intervention) or a loess bio-ball mat (intervention).

Results: In the control group ( = 30), there was a minimal change in blood flow and epidermal temperature in the right and left middle fingers (LMF, RMF) as the mat temperature gradually increased.

Do Medical Graduates from a Rural Longitudinal Integrated Clerkship Work in Similar Rural Communities?

(1) Background: Medical graduates who have undertaken longitudinal rural training have consistently been found to be more likely to become rural doctors and work in primary care settings. A limitation of such findings is the heterogeneous nature of rural medical education and contested views of what constitutes 'rurality', especially as it is often reported as a binary concept (rural compared to metropolitan). To address the identified gaps in workforce outcomes for rural medical training and to demonstrate accountability to the communities we serve, we investigated whether Longitudinal Integrated Clerkship (LIC) graduates are practicing in communities with similar rural classification to those where they trained.
