Abstract
Video-assisted thoracic surgery esophagectomy (VATS-E) may increase the risk of postoperative nausea and vomiting (PONV) because it uses a high dosage of anesthesia through a long operative duration. However, no study has examined the risk factors for PONV after VATS-E. Therefore, we investigated the risk factors for PONV to support the appropriate risk management of PONV after VATS-E. This prospective cohort study included 155 patients who underwent VATS-E at the Showa University Hospital between April 1st, 2020 and November 30th, 2022. The primary outcome was the incidence of PONV within 24 h after surgery. Significant independent risk factors associated with the incidence of PONV were selected using multivariate analysis. The association between the number of risk factors for PONV and incidence of PONV was analyzed. One-hundred fifty-three patients were included in the analysis. The patients' median age was 67 years (range, 44-88), and 79.1% were male. PONV occurred in 35 (22.9%) patients. In the multivariate analysis, remifentanil dosage > 89.0 ng/kg/ min, albumin ≤ 3.5 g/dL, and eGFR < 60 mL/min/1.73 m 2 were independent significant risk factors for PONV. A significant association was observed between the incidence of and the number of risk factors for PONV (0 factor, 5.8%; 1 factor, 27.3%; ≥ 2 factors, 40.0%; p = 0.001). These three risk factors are useful indicators for selecting patients at high risk of developing PONV after VATS-E. In these patients, avoiding the development of PONV will be possible by performing appropriate risk management.

Abstract
BACKGROUND AND OBJECTIVES This study compares the clinical properties of original breast ultrasound images and those synthesized by a generative adversarial network (GAN) to assess the clinical usefulness of GAN-synthesized images. MATERIALS AND METHODS We retrospectively collected approximately 200 breast ultrasound images for each of five representative histological tissue types (cyst, fibroadenoma, scirrhous, solid, and tubule-forming invasive ductal carcinomas) as training images. A deep convolutional GAN (DCGAN) image-generation model synthesized images of the five histological types. Two diagnostic radiologists (reader 1 with 13 years of experience and reader 2 with 7 years of experience) were given a reading test consisting of 50 synthesized and 50 original images (≥1-month interval between sets) to assign the perceived histological tissue type. The percentages of correct diagnoses were calculated, and the reader agreement was assessed using the kappa coefficient. RESULTS The synthetic and original images were indistinguishable. The correct diagnostic rates from the synthetic images for readers 1 and 2 were 86.0% and 78.0% and from the original images were 88.0% and 78.0%, respectively. The kappa values were 0.625 and 0.650 for the synthetic and original images, respectively. The diagnoses made from the DCGAN synthetic images and original images were similar. CONCLUSION The DCGAN-synthesized images closely resemble the original ultrasound images in clinical characteristics, suggesting their potential utility in clinical education and training, particularly for enhancing diagnostic skills in breast ultrasound imaging.

Abstract
Abstract
Background
Recent clinical study suggests newer-generation drug-eluting stents (DES) that combine ultrathin strut and nano-coating with biodegradable polymers sirolimus-eluting stent (BP-SES) could improve long-term clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over current generation DES. However, the details of vascular response in very early and chronic phase have not been systematically addressed.
Objective and method
We exploratory investigate early and chronic vascular response following BP-SES implantation in patients with STEMI to reveal mechanism of the favorable clinical outcomes in recent studies using frequency domain-optical coherence tomography (FD-OCT).
Consecutive twenty-four patients with STEMI who underwent FD-OCT after primary PCI and were eligible for follow-up FD-OCT at 2 weeks and 1 year after implantation were enrolled between June 2018 and August 2020.
OCT was performed immediately after PCI, at 2-weeks (2W) and 1-year (1Y) after the primary PCI. Struts were recorded as uncovered if any part was visibly exposed in the lumen or covered if a layer of tissue covered all reflecting surfaces. Struts of stents that are smaller than 3.0mm of diameter with more than 80μm between the center reflection and the adjacent vessel surface were recorded as malapposed. The reduction of atherothrombotic protrusion burden within the stent was also assessed.
Results
Twenty-four patients (age 64.9±11.4 years, male 83.3%) were enrolled.
The percentage of uncovered struts significantly decreased from post-PCI to 2W follow-up and from 2W follow-up to 1Y follow-up (62±20% post-PCI versus 27±11% at 2W follow up, p<0.0001 and 2W follow-up versus 3.3±3.3% at 1Y follow up, p<0.0001). Malapposed struts also decreased from post-PCI to 2W follow-up (4.1±3.6% post-PCI versus 1.5±2.2% at 2W follow-up, p<0.0001), but no significant difference was shown between 2W follow-up and 1Y follow-up (2W follow-up versus 1.0±2.3 at 1Y follow up, p=0.12). The average protrusion area of athero-thrombotic burden decreased (0.57±0.32 at post-PCI versus 0.42±0.22 mm2 at 2W follow up, p<0.0001) and its volume showed similar tendency (16.6±10.7 at post-PCI versus 12.9±8.23 mm3 at 2W follow up, p=0.0011). Thrombus was shown in all patients at post-PCI, but two patients (8.0%) showed it at 1Y follow-up.
Conclusion(s)
This study elucidated very early and chronic vascular responses following ultrathin strut BP-SES implantation in STEMI patients by FD-OCT. It showed resolution of athero-thrombotic materials in very early phase and favorable progression of strut coverage in very early and chronic phase.

Abstract
Abstract
Background
Tricuspid regurgitation (TR) has long been neglected due to limited therapeutic options. Within the past five years, transcatheter tricuspid valve edge-to-edge repair (T-TEER) has become a valuable tool in the treatment of TR besides diuretic medical therapy and valve surgery. Owing its novelty, data on long-term survival after T-TEER for relevant TR are sparse. Beyond that, there is uncertainty on the impact of TR reduction on outcomes after successful T-TEER.
Purpose
This study sought to investigate long-term survival outcome after T-TEER for relevant symptomatic TR. We evaluated the impact of TR reduction on outcome in patients with successful T-TEER.
Methods
Consecutive patients who underwent successful isolated T-TEER for relevant TR from 2016 until 2022 at a high-volume university center were included in the study. Procedural success was defined as at least one degree TR reduction. Long-term survival endpoint was three-year all-cause mortality. Survival follow-up was completed via phone calls with the patients themselves, the next of kin, local practitioners and using the German national population registry. Post-procedural TR was assessed by interventionalist and echocardiographer at the end of the T-TEER procedure.
Results
A total of 244 patients who underwent successful T-TEER in the study period were included in the present analysis (mean age 77.7±8.7 years; 50.8% female). Patients were highly symptomatic as represented by New York Heart Association functional class ≥ III in 95.9% of cases. TR was 4+ in 128 patients (52.2%), 3+ in 106 patients (43.4%) and 2+ in 10 patients (6.1%). The etiology of TR was predominately functional (88.5%), while 5.4% presented with degenerative TR and 6.1% with TR of mixed etiology. Median time to last contact or death was 365 days (interquartile range 166–809 days). Three-year follow-up was available in 98% of eligible patients. T-TEER was performed using a mean number of 2.0±0.6 devices (Mitra-/TriClip 53%; PASCAL 47%). Post-procedural TR was 1+ in 126 patients (51.6%), 2+ in 101 patients (41.4%) and 3+ in 17 patients (7.0%). Survival rates at one, two and three years were 76%, 68% and 56%. Among patients with procedural success (at least 1° TR reduction), a higher degree in post-procedural TR was associated with a trend towards reduced postinterventional survival (Figure 1). The absolute degree of TR reduction did not impact survival rates in patients with procedural success (Figure 2).
Conclusion
T-TEER effectively reduces TR severity and shows high rates of procedural success. While the extent of TR reduction did not yield prognostic value in terms of long-term survival, the degree of post-procedural TR showed a trend regarding survival outcome. These results indicate that procedural techniques and strategies should be refined to achieve TR1+ at the end of the procedure.

Abstract
Abstract
Background
Right ventricular dysfunction (RVD) is an important predictor for outcome in patients undergoing transcatheter mitral or tricuspid valve edge-to-edge repair (M/T-TEER). Due to the unique anatomy and contraction pattern of the RV, three-dimensional echocardiography (3DE) has emerged as a valuable tool in the assessment of RV function. While 3DE data showed RV reverse remodeling (RVRR) following T-TEER, respective data are absent in the setting of M-TEER.
Purpose
We sought to assess RVRR after M-TEER using 3DE comparing baseline and follow-up RV measurements.
Methods
Patients undergoing M-TEER treatment for relevant MR between August 2016 and February 2021 with eligible transthoracic 3DE of the RV at baseline and follow-up were included in the study. 3DE comprised RV end-diastolic and end-systolic volumes (RVEDV3D, RVESV3D), total RV stroke volume (RVSV3D) and RV ejection fraction (RVEF3D). Further, RV length (RVL3D) as well as RV basal (RVbase3D) and mid-ventricular diameters (RVmid3D) were derived from 3DE. RVRR was assessed as change in the respective 3DE parameters of RV dimensions between baseline and follow-up.
Results
A total of 66 patients (45.5% female; age 78.5±8.2 years; EuroScore II 4.6±3.6%) were included in the study. From baseline to latest available follow-up (median interval 364 days, interquartile range 180–728 days), a significant reduction of RVEDV3D and RVESV3D was observed (RVEDV3D 140.2±50.2 ml to 128.1±46.1 ml, p<0.01 and RVESV3D 93.1±37.8ml to 87.1±34.7ml, p=0.04). The decrease in 3D-derived linear RV dimensions primarily occurred in the septolateral direction, while RV length did not change significantly. The observed RVRR was associated with significant reduction of TR severity. Of note, patients with RVRR showed also left ventricular reverse remodeling (LVRR).
Conclusion
M-TEER is an effective treatment option for patients with MR which leads to LVRR and RVRR.

Abstract
Abstract
Introduction
In our previous report, the time interval from left ventricular (LV) pacing to the earliest onset of QRS (S-QRS interval) has been found to be an independent predictor of mechanical response to cardiac resynchronization therapy (CRT). The S-QRS interval may indicate the conduction disturbance relevant to the localized tissue property such as scar or fibrotic lesion. Therefore, S-QRS interval longer than 37ms was associated with poor response to CRT, and proposed as suboptimal LV lead position. Then, we hypothesized that the longer S-QRS interval at the LV pacing site could be related to long term mortality and heart failure events in patients with CRT.
Methods
This retrospective study included 82 consecutive heart failure patients with sinus rhythm, reduced LV ejection fraction (≤35%), and a wide QRS complex (≥120ms), who undergone CRT implantation between 2012 January and 2017 December. Patients were divided into Short S-QRS group (<37ms, SS-QRS) and Long S-QRS group (≥37ms, LS-QRS) according to the previously reported optimal cut off value. A responder was defined as one with ≥15% reduction in LV end-systolic volume assessed by echocardiography at 6 months after CRT. The primary endpoint was total mortality, which included LV assist device implantation or heart transplantation. The secondary endpoints included the composite endpoint of total mortality or heart failure hospitalization.
Results
The study patients were divided into SS-QRS (N=43, age 65.9±13.2 years, 77% male) and LS-QRS (N=39, age 63.0±13.4, 85% male). In the electrocardiographic measurements, there were no significant differences in baseline QRS duration (162.4±30.3ms in SS-QRS vs. 154.5±31.6ms in LS-QRS, P=0.19) and LV local activation time assessed as Q-LV interval (118.3±34.3ms in SS-QRS vs. 115.3±32.0ms in LS-QRS, P=0.71). S-QRS interval was 25.9±5.3ms in SS-QRS and 51.5±13.7ms in LS-QRS (P<0.01), and the responder rate was significantly higher in SS-QRS compared with LS-QRS (79% vs. 29%, P<0.01). During mean follow up of 47.7±22.4 months, 24 patients (29%) reached to the primary endpoint, while the secondary endpoints were observed in 47 patients (57%). LS-QRS patients had significantly worse event-free survival for both primary and secondary endpoints (Figure). After the multivariate Cox regression analysis, LS-QRS (≥37ms) was an independent predictor of total mortality (HR=2.6, 95% CI: 1.11 to 6.12, P=0.03) and the secondary composite events (HR=2.4, 95% CI: 1.31 to 4.33, P<0.01).
Conclusion
The S-QRS interval longer than 37ms, which may reflect the conduction disturbance relevant to the scar or fibrotic lesion at the LV pacing site, was a significant predictor of the total mortality and heart failure hospitalization. These findings have implications for the optimal LV lead placement in patients with CRT device.

Abstract
Abstract
Background
In the last two decades, catheter ablation (CA) for atrial fibrillation (AF) including pulmonary vein isolation (PVI) has been developed as a standard and effective treatment for atrial fibrillation (AF). In patients with chronic heart failure with reduced left ventricular ejection fraction (LVEF) (HFrEF), PVI CA for AF dramatically improves LVEF, resulting in better clinical prognoses. On the contrary, there still has been no data that PVI CA for AF improves the prognosis in heart failure patients with preserved LVEF (HFpEF).
Purpose
The aim of this study was to evaluate the prognostic impact of PVI CA for AF after the hospitalization due to decompensation of heart failureHF, focusing on LVEF.
Methods
From the database including 1,793 consecutive patients who were hospitalized due to congestive HF, we ultimately analyzed 624 AF patients who were discharged alive. They were assigned into two groups due that PVI CA for AF procedure done after the index hospitalization for HF; the PVI CA group (n=62) and Non-PVI CA group (n=562). For the two groups, we performed propensity-score (PS) matching using variables as follows: age, sex, LVEF, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) and estimated glomerular filtration rate (eGFR) at discharge. Further analysis was performed separately in HFrEF (LVEF <50%) and HFpEF (LVEF >50%). The primary endpoint of this study was death from any cause.
Results
In unmatched patients, Kaplan-Meier analysis showed that patients in the PVI CA group had a significantly lower all-cause mortality than those in the Non-PVI CA group during 678 median follow-up period (Log-rank test: P=0.003, Figure A). In 96 PS-matched patients, patients in the PVI CA group still had lower mortality rate than those in the Non-PVI CA group (hazard ratio 0.28, 95% confidence interval 0.09–0.86, p=0.018, Figure B). When the whole study population was classified into HFrEF and HFpEF, HFrEF patients who received PVI showed a significantly lower mortality than those who did not (p=0.007); whereas, in HFpEF patients, PVI CA for AF did not make statistical difference in all-cause mortality (p=0.061).
Conclusions
In this observational study, PVI CA for AF may improve the mortality in HF patients with reduced LVEF. However, the prognostic impact of PVI CA for AF was not observed in HF patients with preserved LVEF.

Abstract
Abstract
Background
Contrast-induced acute kidney injury (CI-AKI) occurs in 10% to 20% of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI), resulting in a poor short- and long-term prognosis. Reducing the amount of contrast medium can prevent CI-AKI.
Objectives
This study aimed to examine the feasibility and safety of non-contrast PCI in patients with ACS.
Methods
The study was a prospective and single-center registry. Successful non-contrast PCI was confirmed when contrast medium was not injected from the guiding catheter engagement to wire removal in ad-hoc PCI. Coronary angiography after the PCI procedure was permitted once. CI-AKI was defined as an increase in the serum creatinine of ≥0.5 mg/dL from or ≥1.25 times the baseline within 72 hours after PCI. Worsening renal function (WRF) was defined as an increase in the serum creatinine of ≥0.3 mg/dL from baseline after the PCI.
Results
The present study included 106 lesions from 81 patients. Forty-eight lesions were (45%) type C lesions. Successful non-contrast PCI was performed in 95 lesions (90%). CI-AKI was observed in 4 (5%); coronary perforation, 0; no/slow flow, 9 (11%); periprocedural death, 0. The follow-up period was 348 (190–492) days. Successful non-contrast PCI was not associated with the incidence of CI-AKI. However, WRF at 6-month was observed in 18 individuals (22%). Successful non-contrast PCI was inversely associated with WRF (hazard ratio, 0.28; 95% confidence interval, 0.09–0.90) after adjustment for renal function.
Conclusions
The present study suggests that non-contrast PCI is feasible and safe in ACS patients with complex lesions.

Abstract
Abstract
Background
It is known that the early coronary revascularization in patients with non-ST-elevation myocardial infarction (NSTEMI) was associated with favorable clinical outcomes. However, it is still unclear whether this efficacy is equivalent over all the ages of the patients.
Methods
Patients with NSTEMI were screened from the database of the Tokyo CCU network registry. Of those, the patients treated without revascularization (medical treatment) were matched with the patients receiving revascularization by propensity score matching. The probabilities of in-hospital death were calculated in the logistic regression model. In two subgroups stratified according to median of the age (elderly and non-elderly subgroups), the odds ratios of revascularization for in-hospital death were calculated.
Results
In the patients registered between 2013 and 2017, 4,851 patients with NSTEMI were identified. After the screening, 370 patients with medical treatment were matched with 370 patients treated with revascularization. The incidence of in-hospital death was significantly higher in the patients with medical treatment (20.3% vs 13.0%, P=0.01). The two probability curves of in-hospital death in patients with and without revascularization converged as age increased. In the elderly subgroup, the revascularization was not significantly associated with favorable outcome of mortality, whereas it had a significant impact on mortality in the non-elderly subgroup (odds ratio: 0.47 [95% CI 0.23–0.95]).
Conclusion
The impact of revascularization on short-term mortality in patients with NSTEMI tended to be reduced as age increased.

Background
Atrial fibrillation (AF) ablation has been known to contribute to a good prognosis in heart failure patients and improve their systolic function. However, the impact of the post-procedural systolic function on the prognosis in them remains unclear.
Purpose
To investigate the impact of the left ventricular ejection fraction (LVEF) following AF ablation in patients with systolic dysfunction.
Methods
Out of 1078 consecutive patients who underwent AF ablation including extensive pulmonary vein and superior vena cava isolation, 170 with an impaired pre-procedural LVEF (< 50%) were evaluated. They experienced at least one echocardiographic follow-up within one year after the index procedure. The primary outcome was the composite of all-cause death or heart failure hospitalisations (HFHs). In addition, we categorised the patients into three groups according to the post-procedural LVEF within one year to evaluate the outcome: reduced LVEF (rEF, LVEF < 40%), mid-range EF (mrEF, 40% ≤ LVEF < 50%) and preserved LVEF (pEF, LVEF > 50%).
Results
After the index procedure, the patients’ LVEF improved with an average increase of 8%, and the post-procedural LVEF consisted of an rEF in 27 (16%), mrEF in 41 (24%), and pEF in 102 (60%) patients. During a median follow-up of 31 months, a total of 22 (13%) patients experienced the composite outcome, including 18 (11%) HFHs and 10 (6%) all-cause deaths (5 with cardiac issues, 2 any malignancies, and 3 other issues). In the Kaplan-Meier analysis using a Bonferroni correction, there was a significant difference in achieving the outcome between the rEF and mrEF, and rEF and pEF, but not between the mrEF and pEF groups (Figure). In a univariate analysis, the hazard ratio of the outcome was shown as follows: an age ≥ 65 years (hazard ratio, HR: 3.4 [95% confidence interval, CI: 1.4–8.5], p = 0.006), history of HFHs for AF (HR: 1.7 [95%CI: 0.7–4.0], p = 0.25), known underlying heart disease (HR: 1.9 [95%CI: 0.8–1.2], p = 0.13), pre-procedural LVEF < 40% (HR: 3.1 [95%CI: 1.3–7.5], p = 0.009), atrial tachyarrhythmia recurrence (HR: 3.0 [95%CI: 1.2–7.8], p = 0.01), and the post-procedural LVEF category (mrEF and rEF, compared with pEF) (HR: 2.0 [95%CI: 0.4–7.7], p = 0.34; and HR: 8.6 [95%CI: 2.7–37.5], p < 0.0001). Furthermore, in a multivariate analysis, patients with a rEF was the sole independent predictor of the composite outcome after adjusting for confounders including an age≥65 years and pre-procedural LVEF < 40% (HR: 12.0 [95%CI: 3.9–40.0], p < 0.0001), whereas those with a mrEF was not (HR: 1.8 [95%CI: 0.4–7.3], p = 0.42), as compared to those with a pEF.
Conclusions
Patients with a mrEF had a comparable prognosis to those with a pEF in a relatively long follow-up, while those with a rEF had the poorest outcome of the three categories, regardless of the pre-procedural LVEF severity.

Abstract
Abstract
Background
Although the patient's characteristics and outcome of acute myocardial infarction (AMI) have been sufficiently investigated and primary percutaneous coronary intervention (PCI) has been recognized as established treatment strategy, those of recent myocardial infarction (RMI) have not been fully evaluated.
Purpose
The purpose of the present study was to clarify clinical characteristics and in-hospital outcomes of RMI patients from the database of the Tokyo CCU network multicenter registry.
Methods
In Tokyo CCU network multicenter registry database from 2013 to 2016, 15788 consecutive patients were registered as AMI (within 24 hours from onset) and RMI (within 2–30 days from onset). However 1246 patients were excluded because of inadequate data. And we excluded 66 cases because of out of onset period and 129 cases that strongly suspected of involvement of vasospastic events. Therefore, remaining 14347 patients were categorized to RMI group (n=1853) and AMI group (n=12494), and analyzed.
Results
Compared with AMI group, average age was older (70.4±12.9 vs 68.0±13.4 years, p<0.001), male was less (72.4 vs 76.4%, p<0.001), chest pain as chief complaint was less (75.2 vs 83.6%, p<0.001), prevalence of diabetes mellitus was higher (35.9 vs 31.0%, p<0.001), multi-vessel coronary disease was more (54.7 vs 44.6%, p<0.001), patients undergoing PCI was less (79.0 vs 91.2%, p<0.001), and the incidence of mechanical complication was more in RMI group (3.0 vs 1.5%, p<0.001). Although 30-day mortality was equivalent between 2 groups (5.3 vs 5.8%, p=0.360), the major cause of death in AMI group was cardiogenic shock, while in the RMI group it was a mechanical complication. On Kaplan-Meier analysis, the 2 groups had significantly different cumulative incidence of death due to cardiogenic shock (p=0.006, Log-rank test) and mechanical complication (p=0.021, Log-rank test). Furthermore death due to mechanical complication in AMI group was plateau after about 1 week from hospitalization, whereas in RMI group it continued to increase.
Kaplan-Meier analysis
Conclusions
RMI patients had distinctive clinical features in backgrounds and treatment strategies compared with AMI patients, and the major cause of death of RMI patients was different from that of AMI patients. Furthermore, even though treatment during hospitalization of RMI patients was well done, death due to mechanical complications continued to increase.

Abstract
Piccolo (PCLO) inhibits methamphetamine-induced neuropharmacological effects via modulation of dopamine (DA) uptake and regulation of the transport of synaptic vesicles in neuronal cells. Clinical studies have recently suggested that the single nucleotide polymorphism (SNP) rs13438494 in the intron 24 of the PCLO gene is associated with psychiatric disorder, in the meta-analysis of GWAS. Therefore, in this study, we attempted to evaluate the possible role of the PCLO SNP in the mechanisms of uptake of monoamines. To characterize rs13438494 in the PCLO gene, we constructed plasmids carrying either the C or A allele of the SNP and transiently transfected them into SH-SY5Y cells to analyze genetic effects on the splicing of PCLO mRNA. The C and A allele constructs produced different composition of the transcripts, indicating that the intronic SNP does affect the splicing pattern. We also transfected DA and serotonin (5-hydroxytryptamine; 5- HT) transporters into cells and analyzed their uptakes to elucidate the association to psychiatric disorders. In the cells transfected with the C allele, both the DA and 5-HT uptake were enhanced compared to the A allele. We also conducted a clinical study, in order to clarify the genetic associations. PCLO rs13438494 exhibits a relationship with the symptoms of drug dependence or related parameters, such as the age of first exposure to methamphetamine, eating disorders, tobacco dependence and fentanyl requirement. Our findings suggest that rs13438494 is associated with drug abuse and contributes to the pathogenesis of psychiatric disorders via modulation of neurotransmitter turnover.

Abstract
OBJECTIVE Development of the knee joint was morphologically investigated, and the process of cavitation was analyzed by using episcopic fluorescence image capture (EFIC) to create spatial and temporal three-dimensional (3D) reconstructions. METHODS Knee joints of Wister rat embryos between embryonic day (E)14 and E20 were investigated. Samples were sectioned and visualized using an EFIC. Then, two-dimensional image stacks were reconstructed using OsiriX software, and 3D reconstructions were generated using Amira software. RESULTS Cavitations of the knee joint were constructed from five divided portions. Cavity formation initiated at multiple sites at E17; among them, the femoropatellar cavity (FPC) was the first. Cavitations of the medial side preceded those of the lateral side. Each cavity connected at E20 when cavitations around the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) were completed. CONCLUSION Cavity formation initiated from six portions. In each portion, development proceeded asymmetrically. These results concerning anatomical development of the knee joint using EFIC contribute to a better understanding of the structural feature of the knee joint.

Abstract
In this study, we employ a thiol-functionalized polymer (P3HT-SH) as a leverage to tailor the nanomorphology and electronic coupling in polymer-nanocrystal composites for hybrid solar cells. The presence of the thiol functional group allows for a highly crystalline semiconducting polymer film at low thiol content and allows for improved nanomorphologies in hybrid organic-inorganic systems when employing non-toxic bismuth sulfide nanocrystals. The exciton dissociation efficiency and carrier dynamics at this hybrid heterojunction are investigated through photoluminescence quenching and transient absorption spectroscopy measurements, revealing a larger degree of polaron formation when P3HT-SH is employed, suggesting an increased electronic interaction between the metal chalcogenide nanocrystals and the thiol-functionalized P3HT. The fabricated photovoltaic devices show 15% higher power conversion efficiencies as a result of the improved nanomorphology and better charge transfer mechanism together with the higher open circuit voltages arising from the deeper energy levels of P3HT-SH.
