The aim of the work was to establish optimal regimes for sperm cryopreservation when using nano-complexes in environments. The effect of micronutrients (Сu2+, Zn2+, Mn2+) in the polymer- transporters on the survival and fertilization capacity of sperm bulls was investigated. To assess the validity of the complexes N-derivative PEG400, ejaculates were chosen with volume – from 2 to 5 ml, concentration - 0,7 - 1,2×109 cells/ml and sperm activity 7.0 - 8.0 points. Sperm diluted with lactose-yolk-glycerin diluent was divided into parts: control - without addition and experimental with the addition of N-derivative PEG400 (N-PEG400) with a content of 1 ml of solution: Zn2+ - 0,0319 mmol; Cu2+ - 0.0222 mmol; Mn2+ – 0.0359 mmol. In the test sperm samples were added 0.01 ml of solutions of microelements in the polymer composition in ml of diluted ejaculate. Sperm survival was determined in sperm survival samples, motility, respiratory activity, activity of enzymes-markers of sperm fertility - succinate dehydrogenase (SDG) and cytochrome oxidase (CHO).
It was found that the optimal equilibration time of sperm in the presence of microelements in the diluent of N-derivatives of PEG400 is 2.5 hours. In this case, the activity of sperm in the presence of N-derivatives of PEG400 depends on the exposure of spermatozoa over nitrogen vapor and the ability of trace elements to affect metabolic processes in sperm. The highest values of the values of the dynamic parameters of sperm characterized deconserved sperm with the addition to the dilution medium of Zn2+ and Mn2+ N-derivatives of PEG400 and exposure to nitrogen vapors for 8-10 minutes. It was found that Zn2+ and Mn2+ N-derivatives of PEG400 that were added in the diluent after cooled for 8-10 min over nitrogen vapor are characterized by high spermatozoa survival. The results of enzymes-markers activity show that the use of spermatozoa containing PEG400 Zn2+ or Mn2+ N-derivatives after 8-10 min exposure to nitrogen vapor, will ensure fertilization of 65% or more heifers and cows after the first insemination. Studied dose (0.01 ml of 0.0222 mmol solution / ml of diluted semen) of Cu2+ N-PEG400 should not be used in the diluent, when freezing the ejaculate of bulls, as the intensity of oxidative processes was elevated, which was manifested by a decrease in physiological characteristics of germ cells.

Published: February 2021

Background/Objective: Traumatic loss of the lower eye lid is usually combined with the paucity of adjacent flaps to reconstruct composite defects. We describe the use of Glabellar flaps with composite or cartilage graft to reconstruct total or near total composite lower eyelid defects and its outcome.
Material and Methods: This case series was done from January 2017 to December 2019. Patients of either gender, with unilateral post traumatic partial or full thickness lower eyelid defect of 75% eyelid loss or more and Glabellar flap as only remaining option to reconstruct the anterior lamella were included. Patients with medial, lateral canthi, upper eyelid and injuries to orbital contents were excluded. The outcome was assessed on follow-up by the presence of epiphora, ectropion, lagophthalmos, obstruction of vision, graft infection/ extrusion, lower lid retraction, donor site scarring and the need for flap debulking.
Results: 12 patients were operated for lower eyelid defects. 2 (16.7%) patients had total loss of eyelid, while 10 (83.3%) had near total loss, 7 (58.3%) patients presented with partial thickness loss of the eyelid, while rest presented with full thickness loss. 1 patient (8.3%) presented with epiphora, similarly 1 (8.3%) had obstruction of vision in down gaze and 1 (8.3%) had conjunctivitis. None had any other complaint.
Conclusion: Glabellar flap together with composite or cartilage graft is an excellent option to reconstruct total or near total composite lower eyelid defects.

Objective: Hemorrhagic stroke is a common neurosurgical emergency caused by multiple pathological conditions. Brain tumors can also present with acute neurodeficits secondary to hemorrhagic stroke. This study as case series was conducted to report the clinical presentation, radiological findings, causes and management of brain tumors presenting as hemorrhagic stroke.
Materials and Methods: Clinical assessment and radiological investigations were done, including CT brain and MRI brain with contrast. Surgery was done with evacuation of the hematoma and excision of tumor, and the tissue was sent for histopathology. Post operatively patients were shifted to the intensive care unit for monitoring and ventilator support if needed. Adjuvant treatment was guided according to histopathology report.
Results: Total number of patients who were diagnosed to have a bleed in brain tumor were thirteen (n = 13). There were 6 (46%) males and 7 (54%) females. Mean age was 55 years. Among 13 patients, 4 (31%) patients had metastatic brain tumors and 9 (69%) patients had primary brain tumors. Diagnosis was done on CT brain, MRI brain and confirmed on histopathology of tissue obtained during surgery. Out of 13 patients, 5 (38%) patients were asymptomatic prior to hemorrhage and 8 (62%) patients had neurodeficits before and recent episodes of bleeding, which caused deterioration of neurological state.
Conclusion: Malignant primary and metastatic brain tumors can present as acute focal deficits due to brain hemorrhage. Diagnosis is based on clinical presentation, radiological features and histopathology.

Published: February 2021

Riset dan inovasi merupakan cara terbaik untuk membangkitkan daya saing suatu bangsa, dan lembaga pendidikan memegang peranan besar di dalamnya. Sebagai salah satu pelaksana program Madrasah Riset, MAN 2 Kota Malang merupakan madrasah yang berinvestasi pada siswa berkemampuan riset handal. Namun metode penerapan budaya riset tersebut keterbatasan laboratorium, pendanaan, dan pembimbing menyebabkan riset masih sekedar menjadi ekstrakurikuler saja. Siswa masih bergantung pada relasi pembina yang banyak berperan dalam penyediaan alat dan bahan, penggunaan fasilitas, dan juga bimbingan selama penelitian, sehingga kegiatan riset dapat dilakukan dengan biaya yang murah. Solusi terbaik terhadap segala keterbatasan dan ketergantungan ini adalah melalui penerapan suatu sistem berbasis sociopreneur dengan mengintegrasikan seluruh sumber daya dan potensi jaringan antara siswa dan alumni yang ada dengan nama Berdasi (Berdayakan Siswa). Penelitian ini dilakukan untuk meninjau implementasi program Berdasi dalam membangun Budaya Riset di kalangan siswa melaui kerjasama dengan alumni. Implementasi program Berdasi di MAN 2 Kota Malang didasarkan hasil evaluasi pelaksanaan kegiatan penelitian sebelum dilaksanakannya program, dilanjutkan dengan perancangan, rekruitmen, pelaksanaan, dan evaluasi program akhir. Keberhasilan program Berdasi dapat diraih melalui pemenuhan tiga indikator yang dimiliki alumni pada pelaksanaan program, yakni luasnya relasi, penurunan biaya penelitian, dan kemampuan alumni untuk menentukan metode penelitian yang paling sesuai. Melalui program berdasi ini, alumni yang telah diarahkan akan berperan bagi adik kelasnya untuk membantu penentuan dan pelaksanaan tiap tahap penelitian baik dari sisi pengalaman maupun akses laboratorium dan relasi dosen pembimbing. Keseluruhan hasil penelitian ini menunjukkan program Berdasi mampu mewujudkan madrasah unggul dalam bidnag riset, yang berprestasi nasional dan internasional.

El presente trabajo de diploma lleva por título “Sistema de Gestión de Bibliotecas”, se desarrolla en la universidad de Cienfuegos y tiene como objetivo diseñar un sistema informático para gestionar la bibliografía en las unidades de las FAR, a partir de la creación de la Empresa de Tecnologías de la Información para la Defensa (XETID), la cual asumió la responsabilidad de informatizar las unidades militares. Esto trajo consigo el compromiso del soporte y mantenimiento de los softwares que están en explotación. Algunas bibliotecas en unidades militares emplean un gestor bibliográfico creado por el Grupo de Diseño del Ejército, que fue sustituido por XETID, y otras realizan sus labores manualmente porque sus características no se adecuan al mismo, por lo que la empresa XETID con el objetivo de nivelar este proceso, darle soporte y mantenimiento, se ha planteado estandarizar la gestión bibliográfica en las unidades de las FAR. Para el diseño de la aplicación informática se utiliza la arquitectura cliente servidor y el patrón Modelo Vista Controlador y para el modelado se emplea la herramienta Visual Paradigm for UML 8.0. Business Process Model and Notation (BPMN) como lenguaje de modelado para el negocio y Lenguaje Unificado de Modelado (UML) para el diseño.

Esta investigación centra la expresión del “plagio académico” concebida como un factor que afecta a los derechos de los autores e impacta de forma negativa a nivel académico y profesional. Es una investigación de corte cualitativo, donde se analizan y describen a detalle las desventajas de este concepto a través de la técnica de revisión bibliográfica. Los resultados obtenidos demuestran que, el plagio es un obstáculo en el proceso formativo de los estudiantes que limita la capacidad crítica, con causantes principales como el déficit de conocimiento en redacción académica, falta de ética, carencia de sistemas anti-plagio en las instituciones. El plagio es una práctica deshonesta que limita la capacidad de pensamiento crítico, creatividad y ética, tanto en el ámbito académico como en el profesional. El auge de la tecnología ha sido un aliciente para acrecentar las estadísticas de plagio, sin embargo, esto no es un contratiempo reciente, puesto que desde la antigüedad se ha llevado a cabo este tipo de práctica desleal y antiética.

ABSTRACT
This research focuses on the expression of "academic plagiarism" conceived as a factor affecting authors' rights and negatively impacts academically and professionally. It is a qualitative investigation, where the disadvantages of this concept are analyzed and described in detail through the technique of bibliographic review. The results showed that plagiarism is an obstacle in the student process that limits critical ability, with major causes such as the knowledge deficit in academic writing, lack of ethics, and lack of anti-plagiarism systems in institutions. Plagiarism is a dishonest practice that limits critical thinking creativity and ethics, both academically and professionally. The rise of technology has been an incentive to increase plagiarism statistics, however, this is not a recent setback, because this kind of unfair and unethical practice has been carried out since ancient times.
