The interaction between sites A, B and X with passivation molecules is restricted when the conventional passivation strategy is applied in perovskite（ABX3） photovoltaics. Fortunately, the revolving A-site presents an opportunity to strengthen this interaction by utilizing an external field. Herein, we propose a novel approach to achieving an ordered magnetic dipole moment, which is regulated by a magnetic field via the coupling effect between the chiral passivation molecule and the A-site（formamidine ion） in *** strategy can increase the molecular interaction energy by approximately four times and ensure a well-ordered molecular arrangement. The quality of the deposited perovskite film is significantly optimized with inhibited nonradiative recombination. It manages to reduce the open-circuit voltage loss of photovoltaic devices to 360 mV and increase the power conversion efficiency to 25.22%. This finding provides a new insight into the exploration of A-sites in perovskites and offers a novel route to improving the device performance of perovskite photovoltaics.

AIM: To evaluate the ocular response analyzer(ORA)measurements of patients with pathological myopia in comparison with those of emmetropic control subjects,and to investigate the correlation between these ORA measurements and spherical equivalent(SE).METHODS: Measurements of 53 eyes of 53 subjects with pathological myopia(SE >-6.00 D) were compared with those of 60 eyes of 60 emmetropic controls. Corneal hysteresis(CH), corneal resistance factor(CRF),noncontact tonometer intraocular pressure(IOPg), and corneal-compensated IOP(IOPcc) were obtained for each subject. The refractive error value was determined as SE via a cycloplegic refraction ***: The mean age was 54.1±18.9y(ranging from5 to 88) in the pathological myopic group and 56.2±19.0y(ranging from 6 to 89) in the control group. There were no significant differences between the groups concerning age and sex. CH and CRF were significantly lower in the pathological myopic group than in the control group(P <0.001, P =0.005, respectively). IOPcc and IOPg were significantly higher in the pathological myopic group than in the control group(P <0.001, P =0.009,respectively). There were significantly positive correlations between CH and SE(r =0.565, P <0.001) and between CRF and SE(r =0.364, P =0.007). There were significantly negative correlations between IOPcc and SE(r =-0.432, P =0.001) and between IOPg and SE(r =-0.401,P =0.003).CONCLUSION: The present study displayed that pathological myopia affected biomechanical properties measured by ORA. The results of corneal biomechanicalproperties measured by ORA may need to be appreciated by taking refraction into account. Further, pathological myopia might be related with the increased IOP.

Multiple myeloma is a neoplasm of mature and immature plasma cells. A 50-year-old woman with lumbago, dysphagia, and left arm pain was presented. Upper endoscopical examination was performed. There was an exudate-covered ulcer in the distal esophagus, located at 30-32 cm from the incisors, covering the whole mucosa. Histopathological examination of the specimens obtained from the lesion showed the involvement of plasma cells consistent with multiple myeloma of IgG kappa subtype. Esophageal involvement of multiple myeloma should be kept in mind in patients presenting with dysphagia.

BACKGROUND: The highest rate of workplace violence occurs in the health sector, although most cases remain unreported. Emergency services face the majority of these incidents for many reasons, such as the patient profile, long waiting time, and overcrowding. We aimed to determine the characteristics and causes of violence toward emergency physicians. METHODS: The acts of violence toward emergency physicians over a one-year period were prospectively recorded. After a violent incident took place, a third party separately interviewed the physician exposed to the violent behavior and the perpetrator who displayed this behavior. We examined the perpetrator's reasons for violence, their demographic characteristics, and the medical complaints of patients involved in such events to determine the characteristics and causes of ***: Of the violent acts investigated, 85.1% were verbal, and most were directed toward male doctors by the young male relatives of the patients. More than half of the violent acts occurred within the 15 minutes of presentation to emergency service(60.5%) and at off-hours(69.4%). Concerning the health insurance, 20.4% of the cases were covered by the free green card system, and a small number of the perpetrators of violence lived in rural areas(38.2%). The most common reason for violent behavior was the patients' or their relatives' dissatisfaction with the examination or treatment method(38.2%).CONCLUSIONS: Appropriate communication should be established with the patients, and they should be adequately informed about the treatments and interventions to be performed in order to prevent possible acts of violence.
