We demonstrated crystallization retardation of CH3NH3PbI3 thin film during single-coating of presursor solution by simple addition of NaCl. NaCl was co-dissolved into a precursor mixture solution containing PbI2 and methylammonium iodide (MAI). Dissolved NaCl interacted with the PbI2 in solution and produced a stable intermediate phase, which was converted to a full-coverage uniform perovskite absorber layer via reaction with MAI during a single spin coating. The resulting planar-structure perovskite solar cell made from NaCl-supplemented precursor solution showed a 48% improvement in power conversion efficiency (PCE) (maximum value 15...

BACKGROUND: Although pituitary adenomas are considered benign lesions, a small group may exhibit a clinically aggressive behavior, sometimes independently from the classic markers of aggressiveness, including the Ki67 labeling index and/or p53 expression. METHODS: We selected 7 subjects harboring a pituitary tumor with clinical features of aggressiveness. Patients underwent a full preoperative and postoperative endocrinological and neuroradiological work-up. Two were non-functioning, two PRL-secreting, two ACTH-secreting, and one a GH-secreting adenoma...

O-linked β-N-acetylglucosamine (O-GlcNAc) glycosylation is an important post-translational modification in many cellular processes. It is mediated by O-GlcNAc transferases (OGTs), which catalyze the addition of O-GlcNAc to serine or threonine residues of the target proteins. In this study, we expressed a putative Yarrowia lipolytica OGT (YlOGT), the only homolog identified in the subphylum Saccharomycotina through bioinformatics analysis, and the human OGT (hOGT) as recombinant proteins in Saccharomyces cerevisiae, and performed their functional characterization...

BACKGROUND: Life-long specialized care is of the utmost importance to safeguard longevity as well as the quality of life in children diagnosed with a chronic condition (CC). Provision of life-long care, however, infers transfers to different settings in line with person's development status. Young people with CC (10-25 years) will transfer care from a pediatric towards an adult-oriented care setting. As a transfer of care is associated with a change of care context, healthcare team, responsibilities, expectations, and roles, patients need to be prepared for this alteration...

Occupational injuries to digits due to hydrofluoric acid (HFA) are frequently encountered. They have distinctive features, including intense pain, progressive tissue necrosis, and possible bone erosion. To minimize tissue damage, it is of great importance to execute prudent preoperative assessment and determine the correct surgical modality to reconstruct and maintain the function of the hand. However, proper protocols for fingers have not been presented in previous studies. Eight cases with HFA burn to digits were presented to the emergency room...

Prediction models should be externally validated before being used in clinical practice. Many published prediction models have never been validated. Uncollected predictor variables in otherwise suitable validation cohorts are the main factor precluding external validation. We used individual patient data from 9 different cohort studies conducted in the United States, Europe, and Latin America that included 7,892 patients with chronic obstructive pulmonary disease who enrolled between 1981 and 2006. Data on 3-year mortality and the predictors of age, dyspnea, and airflow obstruction were available...

BACKGROUND: N-containing bisphosphonates (BPs), such as pamidronate and risedronate, can inhibit osteoclastic function and reduce osteoclast number by inducing apoptotic cell death in osteoclasts. The aim of this study is to demonstrate the effect of pamidronate, second generation nitrogen-containing BPs and to elucidate matrix metallo-proteinases (MMPs) mRNA expression under serum starvation and/or tumor necrosis factor alpha (TNF-α) stimulation on metabolism of intervertebral disc (IVD) cells in vitro...

There are growing opportunities and demands for image sensors that produce higher-resolution images, even in low-light conditions. Increasing the light input areas through 3D architecture within the same pixel size can be an effective solution to address this issue. Organic photodiodes (OPDs) that possess wavelength selectivity can allow for advancements in this regard. Here, we report on novel push-pull D-π-A dyes specially designed for Gaussian-shaped, narrow-band absorption and the high photoelectric conversion...

GTP and branched-chain amino acids (BCAAs) are metabolic sensors that are indispensable for the determination of the metabolic status of cells. However, their molecular sensing mechanism remains unclear. CodY is a unique global transcription regulator that recognizes GTP and BCAAs as specific signals and affects expression of more than 100 genes associated with metabolism. Herein, we report the first crystal structures of the full-length CodY complex with sensing molecules and describe their functional states...

There is a popular belief that the lunar cycle influences spontaneous delivery in both humans and cattle. To assess this relationship, we investigated the synodic distribution of spontaneous deliveries in domestic Holstein cows. We used retrospective data from 428 spontaneous, full-term deliveries within a three-year period derived from the calving records of a private farm in Hokkaido, Japan. Spontaneous birth frequency increased uniformly from the new moon to the full moon phase and decreased until the waning crescent phase...

We evaluated the effectiveness of aripiprazole among bipolar patients who had switched to this medication as a result of difficulty maintaining on their prestudy atypical antipsychotics (AAPs) because of subsyndromal mood symptoms or intolerance. This study included 77 bipolar patients who were in syndromal remission with an AAP as monotherapy or with an AAP combined with a mood stabilizer(s) who needed to switch from their present AAP because of subsyndromal symptoms or intolerance. At 24 weeks after switching to aripiprazole, the remission rates on the Montgomery-Åsberg Depression Rating Scale (MADRS) and on both the MADRS and the Young Mania Rating Scale were increased significantly in the full sample and in the inefficacy subgroup...

A novel method based on Pulse Coupled Neural Network(PCNN) algorithm for the highly accurate and robust compass information calculation from the polarized skylight imaging is proposed,which showed good accuracy and reliability especially under cloudy weather,surrounding shielding and moon light. The degree of polarization (DOP) combined with the angle of polarization (AOP), calculated from the full sky polarization image, were used for the compass information caculation. Due to the high sensitivity to the environments, DOP was used to judge the destruction of polarized information using the PCNN algorithm...
