The vast majority of pterosaurs are characterized by relatively large, elongate heads that are often adorned with large, elaborate crests. Projecting out in front of the body, these large heads and any crests must have had an aerodynamic effect. The working hypothesis of the present study is that these oversized heads were used to control the left-right motions of the body during flight. Using digital models of eight non-pterodactyloids ("rhamphorhyncoids") and ten pterodactyloids, the turning moments associated with the head + neck show a close and consistent correspondence with the rotational inertia of the whole body about a vertical axis in both groups, supporting the idea of a functional relationship...

Film formation kinetics significantly impact the molecular processability and power conversion efficiency (PCE) of organic solar cells (OSCs). In this article, we report two kinds of ternary random copolymerization polymers, D18-N-p and D18-N-m, to modulate the aggregation ability of the conventional polymer donor D18 by introducing trifluoromethyl substituted pyridine unit at para- and meta-position, respectively. The introduction of the pyridine unit significantly reduced material aggregation ability and adjusted the interactions with acceptor L8-BO, thereby leading to largely changed film formation kinetics with earlier phase separation and longer film formation times, which enlarged fiber sizes in blend films and improved carrier generation and transport...

BACKGROUND: Carcinosarcoma of the gallbladder is a rare malignant tumor with a very poor prognosis. To date, only approximately 100 patients have been reported in the English literature. The prognosis of this tumor type is poor, the preoperative diagnosis is difficult, and there is a possibility of a misdiagnosis. We present an unsuccessful case of carcinosarcoma of the gallbladder with a preoperative misdiagnosis and rapid early postoperative recurrence. Therefore, we have a deeper understanding of the poor prognosis of gallbladder carcinosarcoma (GBC) patients...

Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks...

Despite significant advancements in the care of patients with hypoplastic left heart syndrome (HLHS) morbidity and mortality remain high. Postnatal right ventricular dysfunction and tricuspid regurgitation (TR) are associated with worse outcomes in HLHS. We aim to determine if right ventricle functional parameters and TR on fetal echocardiogram are associated with postnatal outcomes in HLHS patients. Retrospective review was performed on all fetuses with HLHS from 2014 to 2022 at our institution. Initial and follow up fetal echocardiogram measurements of right ventricular myocardial performance index (MPI), fractional area change (FAC) and global longitudinal strain (GLS) were retrospectively measured...

When the authors were 12 and 14 years old, their worlds shifted suddenly without warning or consent, and bifurcated our lives into "a before" and "an after." They were both diagnosed with inflammatory bowel disease (IBD) and found themselves in an "in between" space-young but not healthy, sick but not dying, treatments but not cures, intestines swollen and bleeding but appearing fine on the outside, in every sense the definition: an invisible illness. Their own chronic illness experiences helped to shape our pursuit of careers in healthcare, with one of them choosing pediatric IBD psychology (Jennie David) and the other choosing pediatric gastroenterology (Samantha R...
