- Abstract
Anger is a common emotion in everyday life, and in the context of driving, the experience of greater anger has been positively associated with aggressive behaviour, near-misses and crashes. Although the effect of anger on driver behaviour has been studied, the role of the source of anger and the perceived level of skill of the driver experiencing anger, based on self-reported behaviour, is not well understood. In this context, the aim of the current study was to investigate the relationships of trait anger and driving anger with driver behaviours in relation to driver skills. A total of 369 drivers aged 18–58 years (M = 24.53, SD = 7.65) completed a questionnaire consisting of the Trait Anger Scale (TAS), the Measure for Angry Drivers (MAD), the Driver Skills Inventory (DSI), the Driver Behaviours Questionnaire (DBQ), the Positive Driver Behaviour Scale (PDBS) and the Driving Anger Expression Inventory (DAX). The factor analyses for the Turkish adaptations of the MAD and DAX supported the original factorial structures. For less skilled drivers, experiencing more anger due to the behaviours of others was associated with more errors. For skilled drivers, higher levels of anger due to the behaviours of others were associated with more personal physical anger expression and positive behaviours. Similarly, for the same group of drivers, higher levels of anger due to traffic delays were associated with more errors. The findings revealed a complex relationship between driving-specific anger and driver behaviours based on different levels of driver skills, contrary to non-significant relations of trait anger. Anger provoked by the context/situation-based reason, as opposed to trait anger, was associated with more general driving style (i.e., errors and positive behaviours) through driver skills. For the first time in literature, the relationship between anger and driver behaviour has been addressed in this study within the context of driver skill. The results provided valua

- Abstract
The bread wheat cultivar ( Triticum aestivum L. cv. Sagittario) as a parental line and its mutant, drought-tolerant lines (Mutant lines 4 and 5) were subjected to polyethylene glycol (PEG)-induced drought. Drought stress resulted in decreased chlorophyll levels and the accumulation of proline and TBARS, despite increases in activities of catalase, peroxidase, and superoxide dismutase enzymes. Transcription of the genes encoding these enzymes and delta-1-pyrroline 5-carboxylase synthetase was induced by drought. 2-DE gel electrophoresis analysis identified differentially expressed proteins (DEPs) in the mutant lines, which are distinguished by "chloroplast", "mitochondrion", "pyruvate dehydrogenase complex", and "homeostatic process" terms. The drought tolerance of the mutant lines might be attributed to improved photosynthesis, efficient ATP synthesis, and modified antioxidant capacity. In addition to proteomics data, the drought tolerance of wheat genotypes might also be assessed by chlorophyll content and TaPOX gene expression. To our knowledge, this is the first proteomic analysis of gamma-induced mutants of bread wheat. These findings are expected to be utilized in plant breeding studies.

- Abstract
This study aimed to investigate the mid-to-long-term surgical outcomes of open reduction and internal fixation (ORIF) using a hybrid locking plate/cable technique for the treatment of Vancouver type B1 and type C periprosthetic femoral fractures (PPFs) in a consecutive group of patients from a single tertiary referral center. Twenty-five patients (25 PPFs; 17 female, 8 male) in whom a Vancouver type B1 or type C PPF was diagnosed and treated by a hybrid locking plate/cable technique from 2005 to 2016 were included in the study. Patients' functional status was categorized into 4 groups based on the Harris Hip Score (HHS) at the final follow-up: 70=poor result; 70-80=fair; 80-90=good, and 90-100=excellent. Intraand postoperative complications were also recorded. PPF union was defined clinically as the patient's ability to bear full weight with or without assistance and radiographically as the presence of a callus bridging the fracture. Subgroup analyses were conducted according to the Vancouver classification and type of fixation regarding the HHS and time to union. The mean age was 57 ± 16.6 (range, 17-82) years at the time of the primary hip replacement and 64 ± 18.7 (range, 24-88) years at the time of PPF. The mean follow-up was 5.6 ± 3.3 (range, 2-14) years from primary procedure to PPF and 6.5 ± 4.1 (range, 3-15) years following PPF. There were 7 type B1 and 18 type C PPFs. At the final follow-up, the mean HHS was 71 ± 7.74 (range, 57-89). According to HHS, functional results were poor in 8 patients, fair in 14 patients, and good in 3 patients. No major intra- or postoperative complications were noted. Fracture union was achieved in all patients without complications at an average of 13 ± 4.9 (range, 6-24) weeks. In subgroup analysis, while no significant differences were observed in the HHS (P=.87 for the Vancouver type, P=.96 for the type of fixation), time to union differed among groups. Time to union was significantly shorter in type B1 than in type C PPFs (P=.006). Time to union was considerably shorter in the uncemented group compared to the cemented one (P=.017). Adding cables to the locking plate can provide adequate stability to preserve fracture alignment and achieve bony union in Vancouver type B1 and C PPFs. Although union can be achieved by ORIF in such patients, a longer union time may be required for PPFs in the setting of a cemented femoral stem or Vancouver type C. Level IV, Therapeutic study.

- Abstract
Radiopharmaceuticals are currently a key tool in cancer diagnosis and therapy. Metal-based radiopharmaceuticals are characterized by a radiometal-chelator moiety linked to a bio-vector that binds the biological target (e.g., a protein overexpressed in a particular tumor). The right match between radiometal and chelator influences the stability of the complex and the drug's efficacy. Therefore, the coupling of the radioactive element to the correct chelator requires consideration of several features of the radiometal, such as its oxidation state, ionic radius, and coordination geometry. In this work, we systematically investigated about 120 radiometal-chelator complexes taken from the Cambridge Structural Database. We considered 25 radiometals and about 30 chelators, featuring both cyclic and acyclic geometries. We used quantum mechanics methods at the density functional theoretical level to generate the general AMBER force field parameters and to perform 1 µs-long all-atom molecular dynamics simulations in explicit water solution. From these calculations, we extracted several key molecular descriptors accounting for both electronic- and dynamical-based properties. The whole workflow was carefully validated, and selected test-cases were investigated in detail. Molecular descriptors and force field parameters for the complexes considered in this study are made freely available, thus enabling their use in predictive models, molecular modelling, and molecular dynamics investigations of the interaction of compounds with macromolecular targets. Our work provides new insights in understanding the properties of radiometal-chelator complexes, with a direct impact for rational drug design of this important class of drugs.

- Abstract
Computed tomography (CT) has been recognized as a robust and dependable technique for delineating osseous alterations and anomalies within hard tissues. The necessity for accurate diagnosis and management of patients with temporomandibular disorders in dental practices has increasingly come to the forefront. There is ongoing scholarly debate regarding the equivalence of diagnostic outcomes yielded by cone beam computed tomography (CBCT), which offers greater accessibility in dental settings than traditional CT, in identifying bony changes within the temporomandibular joint (TMJ). Our principal aim was to conduct a systematic review of studies that compare the efficacy of CT and CBCT in the detailed assessment of bone conditions affecting the TMJ. An electronic search was conducted across databases: PubMed, Medline, Web of Science, Cochrane and Scopus. Two independent reviewers screened titles and abstracts against predefined inclusion criteria. The included articles underwent rigorous critical appraisal, during which relevant data were extracted and systematically presented in a tabular format. This systematic review incorporates 5 studies published between 2006 and 2015. In 3 studies, CBCT demonstrated comparable outcomes to CT, while 2 investigations revealed significantly enhanced accuracy for CBCT compared to CT, with reported accuracies of 0.95 ± 0.04, 0.77 ± 0.17, and 89-91% for CBCT. The aggregated evidence from the included studies indicates that CBCT offers comparable or superior accuracy in detecting osseous changes within TMJ structures. Owing to its lower radiation exposure and increased accessibility, CBCT emerges as the preferred choice over conventional CT for evaluating bony structures of the TMJ., (© Pol J Radiol 2024.)

- Abstract
Objective: Numerous factors affect abductor strength after Total hip arthroplasty (THA), including surgical technique, prosthesis type, postoperative rehabilitation program, and preoperative patient condition. We prospectively investigated the effects of the modified Hardinge approach on hip muscle strength, which was evaluated using the isokinetic test, functional results, and gait function of patients who underwent primary THA., Methods: The hip muscles strength were measured using an isokinetic dynamometer. The primary outcomes of the present study were measurement of isokinetic strength of hip abductor muscle strengths using an isokinetic evaluator and gait analyses preoperatively and at 6 months postoperatively in 27 patients., Results: Isokinetic muscle strength test, abductor and other hip circumference groups achieved the preoperative muscle strength at 3 months postoperatively, and the postoperative sixth month values showed a statistically significant improvement compared with the preoperative and third month values. In gait analyze, our temporospatial data showed a slight regression at postoperative 3 months but reached the same values at 6 months postoperatively. Kinematic data showed a significant regression, but the data were not compared with those in the preoperative period., Conclusions: Adequate muscle strength and physiological gait pattern, similar to the preoperative status, can be achieved at 6 months postoperatively., Level of Evidence: Level III., (© 2023.
