Then cornual wedge resections were performed. Two cases were identified as intramural pregnancy by hysteroscopic and laparoscopic view. Most of the intramural pregnancy tissue of one patient was removed by hysteroscopy. The other one converted to laparoscopy.
Laparoscopically assisted hysteroscopic management could be a feasible surgical option to interstitial pregnancies. Further clinical studies are needed to establish detailed criteria to select the appropriate cases for hysteroscopic management.

To investigate whether hemodynamic changes during balloon occlusion test (BOT) predict future heart failure (HF) deterioration after transcatheter atrial septal defect closure (tASD-closure).
Midterm HF deterioration can sometimes occur after tASD-closure in adults. Whether hemodynamic changes during tASD-closure can help identify patients at risk is unknown.
This prospective observational study enrolled 86 consecutive adult patients who underwent tASD-closure. Hemodynamic parameters, including pulmonary capillary wedge pressure (PCWP), were measured at baseline, during BOT, and after tASD-closure. The changes in PCWP during BOT and after tASD-closure were defined as ΔPCWP (Occ-Pre) and ΔPCWP (Post-Pre), respectively. Clinical parameters were evaluated before tASD-closure and during the 3-month follow-up. We assessed the occurrence of HF deterioration (HF requiring hospitalization or additional diuretics) during a 2-year follow-up period and categorized patients into HF (+) and HF (-) groups accordingly. The aforementioned parameters were compared between groups.
Midterm HF deterioration occurred in 12 patients (13.9%). Compared to the HF (-) group, the HF (+) group presented a significantly higher ΔPCWP (Occ-Pre) (9.5 ± 4.4 mmHg vs. 3.0 ± 3.3 mmHg; p < 0.001) and ΔPCWP (Post-Pre) (4.0 ± 2.8 mmHg vs. 0.6 ± 1.8 mmHg; p=0.004). this website Receiver operating characteristic curve analysis showed that the ΔPCWP (Occ-Pre) cutoff value of 5.5 mmHg had excellent ability to predict HF deterioration (Area under the curve 0.886 , p < 0.001; sensitivity 0.917, specificity 0.824).
Increases in PCWP during BOT predict midterm HF deterioration after tASD-closure. Close surveillance may be needed in patients with a ΔPCWP (Occ-Pre) >5 mmHg.

However, the current reaction selectivity remains unsatisfactory. In this study, the bismuth-containing metal-organic framework CAU-17, with morphological variants of hexagonal prisms (CAU-17-hp) and nanofibers (CAU-17-fiber), is prepared at room temperature through a wet-chemical approach and employed as the electrocatalyst for highly selective CO2 -to-formate conversion. An H3 BTC-mediated morphology reconstruction is systematically investigated and further used to build a CAU-17-fiber hierarchical structure. The as-prepared CAU-17-fiber_400 electrodes give the best electrocatalytic performance in selective and efficient formate production with FEHCOO- of 96.4 % and jCOOH- of 20.4 mA cm-2 at -0.9 VRHE . This work provides a new mild approach for synthesis and morphology engineering of CAU-17 and demonstrates the efficacy of morphology engineering in regulating the accessible surface area and promoting the activity of MOF-based materials for ERCO2 .Developing Type-I photosensitizers is considered as an efficient approach to overcome the deficiency of traditional photodynamic therapy (PDT) for hypoxic tumors. However, it remains a challenge to design photosensitizers for generating reactive oxygen species by the Type-I process. Herein, we report a series of α,β-linked BODIPY dimers and a trimer that exclusively generate superoxide radical (O2 -. ) by the Type-I process upon light irradiation. The triplet formation originates from an effective excited-state relaxation from the initially populated singlet (S1 ) to triplet (T1 ) states via an intermediate triplet (T2 ) state. The low reduction potential and ultralong lifetime of the T1 state facilitate the efficient generation of O2 -. by inter-molecular charge transfer to molecular oxygen. The energy gap of T1 -S0 is smaller than that between 3 O2 and 1 O2 thereby precluding the generation of singlet oxygen by the Type-II process. The trimer exhibits superior PDT performance under the hypoxic environment.Nucleotides, amino acids, sugars, and lipids are almost ubiquitously homochiral within individual cells on Earth. While oligonucleotides and proteins exist as one natural chirality throughout the tree of life, two stereoisomers of phospholipids have separately emerged in archaea and bacteria, an evolutionary divergence known as “the lipid divide”. Within this review, we focus on the emergence of phospholipid homochirality and compare the stability of synthetic homochiral and heterochiral membranes in vitro. We discuss chemical probes designed to study the stereospecific interactions of lipid membranes in vitro. Overall, we aim to highlight studies that help elucidate the determinants of stereospecific interactions between lipids, peptides, and small molecule ligands. Continued work in understanding the drivers of favorable interactions between chiral molecules and biological membranes will lead to the design of increasingly selective chemical tools for bioorthogonal labeling of lipid membranes and safer membrane-associating pharmaceuticals.
Imprecise articulation has a negative impact on speech intelligibility. Therefore, treatment of articulation is clinically relevant in patients with dysarthria. In order to be effective and according to the principles of motor learning, articulation therapy needs to be intensive, well organized, with adequate feedback and requires frequent practice.
The aims of this pilot study are (1) to evaluate the feasibility of a virtual articulation therapy (VAT) to guide patients with dysarthria through a boost articulation therapy (BArT) program; (2) to evaluate the acoustic models’ performance used for automatic phonological error detection; and (3) to validate the system by end-users from their perspective.
The VAT provides an extensive and well-structured package of exercises with visual and auditory modelling and adequate feedback on the utterances. The tool incorporates automated methods to detect phonological errors, which are specifically designed to analyse Dutch speech production. A total of 14 subjects with dysarthria evaluated the acceptability, usability and user interaction with the VAT based on two completed therapy sessions using a self-designed questionnaire.
