BACKGROUND:Adjustable piezoelectric effect can promote tissue regeneration and repair.Piezoelectric materials are widely used in weight-bearing tissue engineering. OBJECTIVE:To prepare a piezoelectric film material that can promote bone regeneration,and to explore its structural characterization,electrical output performance,biocompatibility,and effect of electrical output on osteogenic differentiation of rabbit bone marrow mesenchymal stem cells. METHODS:Using poly-3-hydroxybutyrateco/4-hydroxybutyrate(P34HB)as raw material,barium calcium stannate titanate powder(Ba0.94Ca0.06Sn0.08Ti0.92O3,BCST)was added according to mass ratios of 0%,5%,10%,15%,and 20%.Dichloromethane was added to solve P34HB,and the thickness of 150-200 μm BCST/P34HB piezoelectric film was prepared by vacuum drying method.After polarization in the oil bath,the surface morphology,crystal phase composition,piezoelectric coefficient and open circuit voltage were tested.The effect of BCST/P34HB electrical output at 110 Hz and 0.25 N force on the proliferation and osteogenic differentiation of rabbit bone marrow mesenchymal stem cells was tested. RESULTS AND CONCLUSION:(1)Scanning electron microscopy,X-ray diffraction,water contact angle,piezoelectric coefficient and electrical output performance tests showed that when the mass ratio of BCST increased to 20%,the BCST/P34HB piezoelectric film had good piezoelectric properties(d33=5.9 pC/N)and electrical output performance(180 mV),which was closer to the suitable range of 500 mV for electrical stimulation.(2)Live and dead staining showed that on the first day of co-culture,15%group and 20%group showed less red fluorescence.On the 5th day of culture,the number of green fluorescence in each group was significantly higher than that on the first day,and the red fluorescence was not observed in the 10%,15%and 20%groups,and only a small amount of red fluorescence was observed in the 0%and 5%groups.(3)On the 1st,3rd and 5th days of co-culture with rabbit bone marrow mesenchymal stem cells,Almar blue staining exhibited that the number of cells in each group showed an increasing trend with the increase of time.On the 5th day of culture,the number of cells in the 20%group was significantly more than that in the 0%group(P<0.05).(4)On day 10 of osteogenic induction,alkaline phosphatase staining results showed that the positive rate of the 20%group was significantly higher than that of the 0%group(P=0.000 1).On day 21,alizarin red staining and quantitative analysis of calcium nodules showed a similar trend to alkaline phosphatase staining.Compared with the 0%group,the 15%group and 20%group showed significant differences(P<0.01,P<0.000 1).(5)The results showed that 20%BCST/P34HB films had good piezoelectric properties,electrical output properties,biocompatibility and the ability of promoting osteogenic differentiation of bone marrow mesenchymal stem cells.

AIM: To investigate the effect of unilateral endoscopic dacryocystorhinostomy on binocular surface indexes.METHODS: Totally 45 cases with monocular primary acquired nasolacrimal duct obstruction(PANDO)who successfully underwent endoscopic dacryocystorhinostomy between 1 December 2022 and 31 July 2023 were enrolled in the study. Ocular surface indexes, including the non-invasive tear break-up time(NIBUT), Sj&#x0026;#xF6;gren's International Collaborative Clinical Alliance ocular staining score(SICCA OSS), Korb score of lid wiper and Schirmer test scores, were collected preoperatively and at 0.5, 1 and 3 mo post-operatively. Subsequently, various indexes were compared at each time point between the operated and healthy eyes pre- and post-operatively.RESULTS: There was no significant differences between operated and healthy eyes in NIBUT, SICCA OSS, Korb scores and Schirmer test(all P&#x003E;0.05). Furthermore, the Korb scores of operated eye at 0.5, 1 and 3 mo post-operatively were significantly lower than the preoperative value(P=0.034, 0.044, 0.027). Moreover, the Schirmer test score of the operated eye at 1 mo post-operatively was significantly lower than the preoperative value(P=0.0461).CONCLUSION:After a successful endoscopic dacryocystorhinostomy, tear drainage is restored, however, ocular surface damage worsens. These changes typically peak at 1 mo post-operatively before gradually improving.

Application of optical coherence tomography in orthokeratology fitting / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To assess the gap between the peak of the base curve to the surface of the cornea, as well as examines the correlation between the thickness of the tear film and the fitting of the orthokeratology lens through optical coherence tomography(OCT), providing an intuitive and quantitative clinical evaluation method for the fitting of the orthokeratology lens.METHODS: Myopia patients who fitted orthokeratology at our hospital from January to December 2023 were included. Examinations, including naked vision, slit lamp, non-contact intraocular pressure, ocular fundus, eye position, corneal diameter, corneal topography, tear film rupture time, optometry, etc., were performed on all patients before fitting. The trial lens parameter was selected according to the examination results, and fluorescein staining was performed to evaluate lens fitting state after patients adapted to wearing glasses. According to the performance of fluorescein staining, the inspected eyes are divided into three groups: lens loose group, lens fitting group, and lens tight group. In addition, the tear film thickness of three groups of subjects was measured by OCT, and the differences between the three groups of data were evaluated.RESULTS: A total of 49 myopic patients(77 eyes)were included. The average sphere degree was -3.10±1.25 D, the average cylinder degree was -0.43(-0.75, 0)D, the average horizontal keratometry(HK)was 42.48±0.81 D, and vertical keratometry(VK)was 42.98(42.25, 43.50)D. There were 21 cases(34 eyes)in the lens fitting group, with 13 cases of bilateral eyes, 8 cases of one eye, 14 cases(22 eyes)in the lens loose group, with 8 cases of bilateral eyes, 6 cases of one eye, and 14 cases(21 eyes)in the lens tight group, with 7 cases of bilateral eyes, 7 cases of one eye. There was no statistical difference in the main basic data of the subjects in the three groups(all P&#x003E;0.05). OCT showed that the tear film thickness of the lens fitting group, the lens loose group, and the lens tight group was 231.18(219.0, 243.0), 220.41(214.0, 224.3), and 249.00(241.5, 258.0)μm, respectively, and there was statistical significance in the thickness among the three groups(P&#x003C;0.05).CONCLUSION: OCT can serve as a safe and reliable method for measuring the tear film thickness, which can help evaluate the suitability of orthokeratology and provide a non-invasive, more intuitive, and quantitative evaluation method for the fitting and evaluation of orthokeratology.

Instability of tear film and loss of meibomian glands in patients with acne vulgaris / Instabilidade do filme lacrimal e perda de glândulas meibomianas em pacientes com acne vulgaris

ABSTRACT Purpose: In this prospective study, we compared ocular clinical variables in patients with acne vulgaris with those of healthy controls. These variables included tear film break-up time, meibomian gland dropout rate, and anterior chamber parameters. Methods: Our sample comprised 73 eyes from 73 patients with acne vulgaris and 67 eyes from 67 healthy controls. All participants underwent a non-invasive first tear film break-up time test and the average tear film break-up time was evaluated. Meibography was used to identify any meibomian gland dropout. The parameters of the cornea and anterior chamber were measured using Scheimpflug topography imaging. Finally, the ocular surface disease index questionnaire was administered to score each participant on their subjective experience of ocular complaints. Results: The noninvasive first tear film break-up time values of the acne vulgaris Group and the control Group were 4.7 ± 2.8 and 6.4 ± 3.5 sec, respectively. There was a significant difference between the groups (p=0.016). The number of eyes with tear break-up at any time during the measurement period was also significantly higher in the acne Group (p=0.018). In the acne vulgaris Group, the mean meibomian gland dropout rates were 33.21 ± 15.5% in the upper lids and 45.4 ± 14.5% in the lower lids. In the control group, these rates were 15.7 ± 6.9% and 21 ± 9.7% respectively. Dropout was significantly higher in the acne group for both the upper and lower lids (p=0.000). Conclusion: We found impaired tear stability in patients with acne vulgaris and a high rate of meibomian gland dropout. These glands play a key role in tear stability and their dropout is likely to result in evaporative dry eye. Measurement of the variables in this study allows objective diagnosis of this condition using a non-invasive, dye-free methodology, with minimum contact.

RESUMO Objetivo: Neste estudo prospectivo, pacientes com acne vulgaris e indivíduos saudáveis do grupo controle foram comparados em relação ao tempo de ruptura do filme lacrimal, taxa de abandono de glândulas meibomianas e parâmetros da câmara anterior, usando o tempo de ruptura do filme lacrimal topográfico não invasivo, meibografia não invasiva e fotografia de Scheimpflug, respectivamente. Métodos: Setenta e três olhos de 73 pacientes com acne vulgaris e 67 olhos de 67 indivíduos saudáveis foram incluídos. Todos os participantes submetidos ao primeiro tempo de ruptura do filme lacrimal não-invasivo e ao tempo médio de ruptura do filme lacrimal não-invasivo foram avaliados pelo uso do tempo de ruptura do filme lacrimal; perda de glândulas meibomianas foram avaliadas por meibografia; os parâmetros da córnea e da câmara anterior foram medidos por fotografia de Scheimpflug; e, finalmente, as queixas oculares subjetivas foram pontuadas com o uso do questionário do Indice de doenças de superfície ocular. Resultados: Os valores do tempo de ruptura do primeiro filme lacrimal não-invasivo do Grupo com acne vulgaris e do Grupo controle foram 4,7 ± 2,8 e 6,4 ± 3,5 segundos, respectivamente, refererindo-se a uma diferença significativa entre os valores dos grupos (p=0,016). Qualitativamente, o número de olhos com ruptura lacrimal a qualquer momento durante o período de medição foi significativamente maior no grupo de pacientes. (p=0,018). No Grupo com acne vulgaris, a perda de glândulas meibomianas nas pálpebras superiores foi de 33,21 ± 15,5% e nas pálpebras inferiores foi de 45,4 ± 14,5%; por outro lado, no Grupo controle foi de 15,7 ± 6,9% e 21 ± 9,7% respectivamente; ambos os casos referem-se a uma diferença significativa entre os grupos (p=0,000). Conclusão: Encontramos estabilidade comprometida do filme lacrimal em pacientes com acne vulgaris. No entanto, o comprometimento foi de grau muito menor, em comparação com a taxa de perda das glândulas meibomianas que desempenham um papel fundamental na estabilidade do filme lacrimal. Esta condição pode ser documentada de forma objetiva - uma metodologia parcialmente sem contato, totalmente não-invasiva e livre de corantes.

O fascismo e os usos políticos do corpo negro de Jesse Owens no filme "Raça" (2016) / El fascismo y los usos políticos del cuerpo negro de Jesse Owens en la película "Race" (2016) / Fascism and the political exploitation of Jesse Owens' black body in the movie "Race" (2016)

O escrito tem como objetivo interpelar o fascismo propagado no filme "Raça" (2016), tensionando-o a partir de questões ligadas à raça, à eugenia, ao dispositivo da imunidade e às políticas do corpo e da vida como formas de regulação. A partir de trechos do filme, discutem-se os modos pelos quais os argumentos científicos embasam as possibilidades de eliminação de uns em detrimento da valoração da vida de outros. Os mecanismos fascistas descritos e analisados no filme operam como práticas biopolíticas por meio de dispositivos diversos. Entende-se que isso conforma práticas políticas de regulação sobre os corpos na direção da manutenção ou supressão da vida, de acordo com as características que são atribuídas, arbitrariamente, aos indivíduos e à população. Considera-se que o filme é retrato de um contexto em que tais práticas foram exacerbadas ao limite, e que o esporte olímpico e os Jogos Olímpicos são arenas privilegiadas paras esses ensaios sociais

El objetivo del escrito es cuestionar el fascismo propagado en la película "Raça" (2016) tensionando lo mismo desde cuestiones vinculadas a la raza, la eugenesia, el dispositivo de inmunidad y las políticas corporales y de vida como formas de regulación. Utilizando extractos de la película, discutimos las formas en que los argumentos científicos sustentan las posibilidades de eliminar a algunos en detrimento de valorar la vida de otros. Los mecanismos fascistas descritos y analizados en la película operan como prácticas biopolíticas a través de diferentes dispositivos. Se entiende que esto configura prácticas políticas de regulación de los cuerpos hacia el mantenimiento o supresión de la vida, según las características que arbitrariamente se atribuyen a los individuos y a la población. La película se considera un retrato de un contexto en el que tales prácticas se exacerbaron hasta el límite, y el deporte olímpico y los Juegos Olímpicos son escenarios privilegiados para estos ensayos sociales

This paper aims to question the fascism propagated in the film "Race" (2016), putting it under pressure based on issues related to race, eugenics, the device of immunity, and the politics of the body and life as forms of regulation. Excerpts from the film discuss how scientific arguments support the possibility of eliminating some at the expense of valuing the lives of others. The fascist mechanisms described and analyzed in the film operate as biopolitical practices through various devices. It is understood that this shapes political practices of regulating bodies to maintain or suppress life according to the characteristics that are arbitrarily attributed to individuals and the population. The film portrays a context in which these practices have been taken to the limit, with Olympic

Producción y distribución de largometrajes de ficción en maranhão: contradicciones de un mercado invisible en brasil

El estado de Maranhão ocupa un escenario peculiar en el mercado cinematográfico brasileño. Las producciones de ficción en forma de largometrajes tuvieron sus primeras incursiones a mediados de la década de 2000. En un marco desarrollado por la investigadora en su disertación de maestría en curso de História (Silva, 2018), y actualizado hasta 2022, catalogamos veintidós películas, solo seis de los cuales fueron registrados en la Agencia Nacional de Cine. La principal metodología utilizada fue la recolección e interpretación de datos, además de entrevistas no estructuradas o no estructuradas (Lakatos y Marconi, 2003). Como principales resultados podemos señalar: en Maranhão, el mercado es predominantemente informal, con momentos ocasionales de formalidad. La conclusión inicial de nuestra investigación es que el factor económico asociado a la falta de políticas públicas, sumado a la falta de cursos de educación superior en la zona, son los principales impulsores de este incipiente escenario.

The State of Maranhão occupies a peculiar scenario in the Brazilian film market. Fiction productions in the form of feature films had their first forays in the mid-2000s. In a framework developed by the researcher in her masters dissertation in History (Silva, 2018), and updated up to 2022, we cataloged twenty-two films, only six of which were registered in the National Film Agency. The main methodology to be used will be the collection and interpretation of data, in addition to unstructured or unstructured interviews (Lakatos and Marconi, 2003). As main results, we can point out that, in Maranhão, the market is predominantly informal with occasional moments of formality. The initial conclusion of our research is that the economic factor associated with the lack of public policies, added to the lack of higher education courses in the area, are the main drivers of this incipient scenario.

Effect of Clinician-directed Technical Specifications on Entrance Skin Doses in Neonates

Objectives: To compare the entrance skin doses (ESD) before and after implementation of a radiation safety policy in neonates (RSN), which focused on clinician-directed technical specifications on the digital X-ray machine. Methods: Prospective observations included two sets of X-rays: Before (BRSN) and after (ARSN) implementation of RSN (documented indication for Xray/expected posttest findings, settings of 40 kVp, 0.5 mAs, film-focus distance 100 cm, gonadal-shield, optimal collimation, and post-shoot image-enhancement). Results: 33 and 32 X-rays were analyzed in respective groups. Mean (SD) of calculated and machine-quantified ESD (µGy/m2) was higher in BRSN group as compared to ARSN group (P <0.001). All ARSN X-rays were interpretable for expected post-test findings. Conclusion: Clinicians’ cognizance of ability to make consequential bedside technical specifications, can reduce ESD without affecting interpretability. These single observations could have a larger impact in sick neonates, where multiple X-rays are done.

Comparison of strip meniscometry and Schirmer tear test results and tear film breakup time between healthy dogs and dogs with dry eye disease / Comparação entre o teste de meniscometria em tira, o teste lacrimal de Schirmer e o tempo de ruptura do filme lacrimal em cães normais e com olho seco

ABSTRACT Purpose: To compare strip meniscometry and Schirmer tear test 1 results and tear film breakup time between dogs with normal eyes and dogs diagnosed with keratoconjunctivitis sicca. Methods: One-hundred fifty-six eyes of 78 dogs, 88 normal eyes, and 68 eyes diagnosed with keratoconjunctivitis sicca were included in the study. The tests were performed in the following sequence: Schirmer tear test 1 was used to allocate the dogs to the normal or keratoconjunctivitis sicca group, followed by the strip meniscometry test and tear film breakup time measurement. Results: The results (mean ± standard deviation) of the tests in the normal group were as follows: Schirmer tear test 1, 22.75 ± 3.88 mm/min; strip meniscometry test, 10.01 ± 2.35 mm/5 sec; and tear film breakup time, 25.82 ± 5.47 sec. In the keratoconjunctivitis sicca group, the results were as follows: Schirmer tear test 1, 6.10 ± 4.44 mm/min; strip meniscometry test, 3.03 ± 2.62 mm/5 sec; and tear film breakup time, 10.78 ± 4.23 sec. The Spearman correlation coefficient in the keratoconjunctivitis sicca group was very high, with a significant difference between the strip meniscometry test and Schirmer tear test 1 (r=0.848, p<0.001), and moderate and significant between the strip meniscometry test and tear film breakup time (r=0.773, p<0.001). The cutoff for the strip meniscometry test for keratoconjunctivitis sicca was 7.0 mm/5 sec. Keratoconjunctivitis sicca was suspected when the values were <10 mm/5 sec. Conclusions: This study provided strip meniscometry test values from dogs with normal eyes and eyes with keratoconjunctivitis sicca, with high sensitivity and specificity compared with those of the Schirmer tear test 1. In the future, the strip meniscometry test may be another important quantitative test and could complement the gold standard Schirmer tear test for the diagnosis of keratoconjunctivitis sicca in dogs, an excellent animal model for the study of the disease.

RESUMO Objetivo: Comparar o teste de meniscometria em tira com o teste lacrimal de Schirmer 1 e o tempo de ruptura do filme lacrimal, em cães com olhos normais e cães com diagnóstico de ceratoconjuntivite seca. Métodos: Cento e cinquenta e seis olhos de 78 cães, 88 olhos normais e 68 olhos com diagnóstico de ceratoconjuntivite seca. Os testes foram realizados na seguinte sequência: o teste lacrimal de Schirmer 1 foi utilizado para alocar os cães no grupo normal ou no grupo ceratoconjuntivite seca, seguido pelo teste de meniscometria em tira e tempo de ruptura do filme lacrimal. Resultados: As médias e desvios-padrão para os olhos normais foram: teste lacrimal de Schirmer 1 = 22,75 ± 3,88 mm / min; teste de meniscometria em tira = 10,01 ± 2,35 mm / 5 seg; tempo de ruptura do filme lacrimal = 25,82 ± 5,47 seg; e para os olhos do grupo ceratoconjuntivite seca foram: teste lacrimal de Schirmer 1 = 6,10 ± 4,44 mm / min; teste de meniscometria em tira = 3,03 ± 2,62 mm / 5 seg; tempo de ruptura do filme lacrimal = 10,78 ± 4,23 seg. O teste de correlação de Spearman no grupo ceratoconjuntivite seca foi muito alto, com diferença significativa entre teste de meniscometria em tira e teste lacrimal de Schirmer 1 (r=0,848, p<0,001), moderada e significativa entre teste de meniscometria em tira e tempo de ruptura do filme lacrimal (r=0,773, p<0,001). O cut-off para teste de meniscometria em tira para ceratoconjuntivite seca foi identificado em 7,0 mm / 5 seg, valores abaixo de 10 mm / 5 seg podem ser considerados suspeitos para KCS. Conclusões: Este estudo forneceu valores de teste de meniscometria em tira em olhos normais e com ceratoconjuntivite seca em cães, revelando alta sensibilidade e especificidade em comparação com o teste lacrimal de Schirmer 1. No futuro, o teste de meniscometria em tira pode ser outro teste quantitativo importante e pode complementar o teste lacrimal de Schirmer padrão ouro para o diagnóstico de ceratoconjuntivite seca em cães, um excelente modelo animal para o estudo de ceratoconjuntivite seca.
