Abstract
OBJECTIVE Papillary fibroelastomas are associated with an increased risk of embolic strokes. Excision of papillary fibroelastomas may be the primary indication for surgery (primary) or performed during other cardiac operations (secondary). The present study summarizes our experience with primary and secondary fibroelastoma surgery. METHODS We analyzed the medical records of patients who underwent surgical excision of papillary fibroelastoma between January 1998 and February 2020. Patient characteristics, indications for operation, tumor size and location, and operative and long-term outcomes were evaluated. RESULTS Among the 294 patients (median age: 66 years, 62% female), papillary fibroelastoma was the primary indication for surgery in 136 patients (46%), and 51% of patients had a history of stroke or transient ischemic attack. When papillary fibroelastoma was a secondary indication for surgery (158 patients, 54%), the lesion was identified preoperatively in 39%. Papillary fibroelastomas were located most commonly on the aortic valve and least commonly in the right side of the heart. For valvular papillary fibroelastoma resected from a normal valve, valve shave was sufficient in 96% (196/205). Operative mortality was low in both groups (primary, 0% vs secondary, 2.5%, P = .13), and early neurologic events occurred in 1.3%. Recurrence rate was 15.8% at 10 years. The estimated survival for patients with primary papillary fibroelastoma at 10 years was 78.4%, whereas for secondary papillary fibroelastoma removal it was 53.6% (log rank, P = .003). CONCLUSIONS Resection of papillary fibroelastomas can be performed safely, with preservation of the native valve, and with low rates of neurologic events. Operative and long-term outcomes after fibroelastoma resection are excellent.

Abstract
AIM The aim of this systematic review is to explore the pathology, diagnosis, treatment, and genetic basis of Primary Failure of Eruption (PFE) in the field of pediatric dentistry and orthodontics. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed for this review. The databases PubMed, Science Direct, Scopus, and Web of Science were searched from 1 July 2013 to 1 July 2023, using keywords "primary failure of tooth eruption" OR "primary failure of eruption" OR "tooth eruption failure" OR "PFE" AND "orthodontics". The study selection process involved screening articles based on the inclusion and exclusion criteria. RESULTS A total of 1151 results were obtained from the database search, with 14 papers meeting the inclusion criteria. The review covers various aspects of PFE, including its clinical features, diagnosis, treatment options, and genetic associations with mutations in the PTH1R gene. Differentiation between PFE and Mechanical Failure of Eruption (MFE) is crucial for accurate treatment planning. Orthodontic and surgical interventions, along with multidisciplinary approaches, have been employed to manage PFE cases. Genetic testing for PTH1R mutations plays a significant role in confirming the diagnosis and guiding treatment decisions, although some cases may not be linked to this mutation. CONCLUSIONS This systematic review provides valuable insights into the diagnosis, treatment, and genetic basis of PFE. Early diagnosis and personalized treatment planning are crucial for successful management. Genetic testing for PTH1R mutations aids in accurate diagnosis and may influence treatment decisions. However, further research is needed to explore the complex genetic basis of PFE fully and improve treatment outcomes for affected individuals.

Abstract
Pupillometry - the study of temporal changes in pupil diameter as a function of external light stimuli or cognitive processing - requires the accurate and gaze-angle independent measurement of pupil dilation. Expected response amplitudes often are only a few percent relative to a pre-stimulus baseline, thus demanding for sub-millimeter accuracy. Video-based approaches to pupil-size measurement aim at inferring pupil dilation from eye images alone. Eyeball rotation in relation to the recording camera as well as optical effects due to refraction at corneal interfaces can, however, induce so-called pupil foreshortening errors (PFE), i.e. systematic gaze-angle dependent changes of apparent pupil size that are on a par with typical response amplitudes. While PFE and options for its correction have been discussed for remote eye trackers, for head-mounted eye trackers such an assessment is still lacking. In this work, we therefore gauge the extent of PFE in three measurement techniques, all based on eye images recorded with a single near-eye camera. We present both real world experimental data as well as results obtained on synthetically generated eye images. We discuss PFE effects at three different levels of data aggregation: the sample, subject, and population level. In particular, we show that a recently proposed refraction-aware approach employing a mathematical 3D eye model is successful in providing pupil-size measurements which are gaze-angle independent at the population level.

Abstract
Papillary fibroelastomas (PFE) are benign neoplasms, mostly located on valvular surfaces with high embolic potential. This study presents a 27-year single institutional experience on surgical treatment of PFE in an adult patient- cohort with long-term follow-up. This study was approved by the institutional review board. Date and number of IRB approval: 11/23/2017, Institutional Review Board approval number A2014-0149. The need for individual patient consent was waived. We retrospectively evaluated all patients who underwent cardiac surgery for suspected space-occupying lesions in the observation period between June 1991 and June 2018 at our hospital. Clinicopathological features, imaging characteristics, surgical procedures and disease outcome were analyzed. 120 patients were diagnosed with various primary/secondary cardiac tumors and histology confirmed 21 PFEs were found in 16 patients. There was no significant age difference between patients with valvular vs nonvalvular PFEs (P = 0.26). Valvular lesions were found in aortic valve (n = 6), mitral valve (n = 2) and tricuspid valve (n = 1). Nonvalvular PFEs were found in right atrium (n = 2), left ventricle (n = 2), left atrial appendage (n = 2) and aortic wall (n = 1). Valvular lesions were significantly smaller in size compared to non-valvular lesions (P = 0.0013). Left-side PFEs were associated with a high embolization episodes (10/13 patients, 77%) not related to the size. One patient died in-hospital. All other patients were discharged out of the hospital postoperative. Follow-up was performed regularly for a median of 2.8 years (range 0.1-11 years) postoperative. Nonvalvular PFE tended to be larger in size and at least when located on the left sided heart had equally high propensity to embolize compared to valvular PFE. We strongly advocate surgical excision in all left-sided PFE.

Abstract
Collecting 130 electronic medical records and diagnoses from emergency room stays of eleven patients with confirmed psychogenic nonepileptic seizure (PNES) over a 17-year period (2001-2018), 48 different diagnostic terms were retrieved. This emphasized the need for a consensual terminology encompassing not only PNES but also all functional transient (paroxysmal) events, including episodes of motor or sensory deficits, and cognitive symptoms. Rather than defining what it is not (PNES, stroke mimicks…), it would be more accurate to define what it is: a paroxysmal functional event.

Abstract
BACKGROUND Primary failure of eruption (PFE) is a rare disease defined as incomplete tooth eruption despite the presence of a clear eruption pathway. Orthodontic extrusion is not feasible in this case because it results in ankylosis of teeth. To the best of our knowledge, besides the study of Ahmad et al. (Eur J Orthod 28:535-540, 2006), no study has systematically analysed the clinical features of and factors associated with PFE. Therefore, the aim of this study was to systematically evaluate the current literature (from 2006 to 2017) for new insights and developments on the aetiology, diagnosis, genetics, and treatment options of PFE. METHODS Following the PRISMA guidelines, a systematic search was performed using the PubMed/Medline database for studies reporting on PFE. The following terms were used: "primary failure of tooth eruption", "primary failure of eruption", "tooth eruption failure", and "PFE". RESULTS Overall, 17 articles reporting clinical data of 314 patients were identified. In all patients, the molars were affected. In 81 reported cases, both the molars and the premolars were affected by PFE. Further, 38 patients' primary teeth were also affected. In 27 patients, no family members were affected. Additional dental anomalies were observed in 39 patients. A total of 51 different variants of the PTH1R gene associated with PFE were recorded. CONCLUSIONS Infraocclusion of the posterior teeth, especially if both sides are affected, is the hallmark of PFE. If a patient is affected by PFE, all teeth distal to the most mesial tooth are also affected by PFE. Primary teeth can also be impacted; however, this may not necessarily occur. If a patient is suspected of having PFE, a genetic test for mutation in the PTH1R gene should be recommended prior to any orthodontic treatment to avoid ankylosis. Treatment options depend on the patient's age and the clinical situation, and they must be evaluated individually.

Abstract
Under anaerobic conditions, Escherichia coli can carry out a mixed-acid fermentation that ultimately produces molecular hydrogen. The enzyme directly responsible for hydrogen production is the membrane-bound formate hydrogenlyase (FHL) complex, which links formate oxidation to proton reduction and has evolutionary links to Complex I, the NADH:quinone oxidoreductase. Although the genetics, maturation, and some biochemistry of FHL are understood, the protein complex has never been isolated in an intact form to allow biochemical analysis. In this work, genetic tools are reported that allow the facile isolation of FHL in a single chromatographic step. The core complex is shown to comprise HycE (a [NiFe] hydrogenase component termed Hyd-3), FdhF (the molybdenum-dependent formate dehydrogenase-H), and three iron-sulfur proteins: HycB, HycF, and HycG. A proportion of this core complex remains associated with HycC and HycD, which are polytopic integral membrane proteins believed to anchor the core complex to the cytoplasmic side of the membrane. As isolated, the FHL complex retains formate hydrogenlyase activity in vitro. Protein film electrochemistry experiments on Hyd-3 demonstrate that it has a unique ability among [NiFe] hydrogenases to catalyze production of H2 even at high partial pressures of H2. Understanding and harnessing the activity of the FHL complex is critical to advancing future biohydrogen research efforts.

Abstract
Spontaneous aggregation of Aβ is a key factor in the development of Alzheimer's disease. In searching for Aβ aggregation inhibitors from traditional Chinese herbal medicines, we identified two active compounds from Psoraleae Fructus, namely isobavachalcone and bavachinin. We further demonstrated that the two compounds modulate Aβ42 aggregation process through different mechanisms. Isobavachalcone significantly inhibits both oligomerization and fibrillization of Aβ42, whereas bavachinin inhibits fibrillization and leads to off-pathway aggregation. Both of the compounds attenuated Aβ42-induced toxicity in a SH-SY5Y cell model. These findings may provide valuable information for new drug development and Alzheimer's therapy in the future.
