Cold and Fertile: Cryopreservation as an Innovative Tool in Addressing Challenges in Teratozoospermia

引用

Journal of Biosciences and Medicines 2024年第2期12卷 274-281页

作者： Víctor Manuel Soto-Márquez Jorge mulia-Rodríguez Daniel Osorio-González Molecular Biophysics Laboratory Faculty of Sciences Autonomous University of State of Mexico Toluca Mexico

Teratozoospermia is an infertility issue that affects a significant number of couples of reproductive age. One of the potential causes contributing to the global decline in seminal quality includes factors such as diet, alcohol and tobacco consumption, high levels of stress, and environmental influences. This underscores the need to preserve the fertility of these patients through cryopreservation techniques. In this review, we explore the latest methods for freezing seminal samples, highlighting their advancements and advantages in addressing the challenge of perpetuating animal species, particularly in the context of human infertility.

Application of a Pulsed Electric Field to Modify the Free Energy of the Active Site of an Azoreductase

引用

Journal of Applied Mathematics and Physics 2024年第1期12卷 249-255页

作者： Jesus Magyber de Jesus Miranda Pedro Guillermo Reyes-Romero Jorge mulia-Rodríguez Daniel Osorio-González Molecular Biophysics Laboratory Faculty of Sciences Autonomous University of State of Mexico Toluca Mexico Advanced Physics Laboratory Faculty of Sciences Autonomous University of State of Mexico Toluca Mexico

The Gibbs free energy is strongly related to the stability and catalytic function of an enzyme through the energetic changes that occur in the chemical reactions the enzyme catalyzes. In this in silico study, a pulsed electric field was applied to an azoreductase, and its effect on the Gibbs free energy of molecular docking with two dyes was measured. We propose that certain stimuli from a pulsed electric field favor the structural stability of the enzyme by promoting an arrangement in the active site, potentially leading to an enhancement of enzymatic activity overall.

Objective: To optimize the ionic liquid based microwave-assisted extraction(IL-MAE)of polyphenolic content from Peperomia pellucida(L) ***: The IL-MAE factors as experimental design parameters, including microwave power, extraction time, ionic liquid concentration, and liquid–solid ratio had been involved. Response surface methodology and Box–Behnken design were used to obtain predictive model(multivariate quadratic regression equation) and optimization of the extraction process. The response surface was analyzed by using the yields of total polyphenolic content as response ***: Based on the obtained results the optimum extraction condition, including microwave power of 30% Watts, extraction time of 18.5 min, the ionic liquid concentration of 0.79 mol/L, and the liquid–solid ratio of 10.72 mL/g 1-Buthyl-3-methylimidazolium tetrafluoroborate([bmim]BF_4) as a solvent was selected. The regression model was obtained to predicts the yields from Peperomia pellucida:Y = 30.250 – 1.356X_1+ 2.655X_2+ 2.252X_3– 0.565X_4+ 0.990 X_1X_3– 8.172X_1X_4– 3.439 X_3X_4– 4.178 X_1~2– 3.210 X_3~2– 6.786 X_4~2– 7.290 X_1~2X_3+ 5.575X1_X_3~2– 4.843 X_3~2X_4 with R^2= 0.82519. Scale-up confirmation test was obtained the maximum yields of total polyphenolics content with the amount of 31.172 5 mg GAE/***: The IL-MAE method produced a higher extraction polyphenolic and performed rapidly, easily and efficiently.

目前,印度尼西亚的森林资源信息管理仍然停留于使用GIS的部分功能模块对森林资源进行管理的阶段,能够将森林资源属性数据及地图数据整合在一起的系统开发仍然空白。而购买国外商业性的林业信息管理软件不仅价格昂贵,导致林场的森林资源信息管理成本高昂,而且此类林业软件往往不符合林场的实际需要。因此,亟需开发能够将林场的属性数据及图形数据集成与一个系统中的软件,以方便林场管理人员对森林资源信息管理,提高管理水平及效率。本研究以Parung Panjang林场为研究点,以现有二类调查数据和林场基本图为数据源,以建立区域林业专题地理信息系统为核心,进行了GIS系统集成技术在此系统中的应用研究,并结合印度尼西亚林场的实际需要开发了部分相关功能模块。本项研究使用Visual Basic 6.0平台和MapObjects嵌入式的地理信息系统ActiveX控件,包含组件对象模块COM、环境系统研究所(ESRI公司)研发的地理信息系统,首次实现了印度尼西亚林业二类调查数据的图文一体化管理,具备多期数据同时管理分析的功能,以及数据的编辑、查询、更新等功能,如图层操作,地图缩放,地图属性管理,数据查询,数据编辑,以及统计图显示等。该系统可以根据用户的要求根据时间、林班和小班或其他特定条件进行空间数据和属性数据查询。同时,系统能够对以前的森林统计数据通过灵活多样的方式进行对比分析。该系统的研制是适应印度尼西亚森林资源管理新形势的需要,填补了印度尼西亚森林资源信息管理的一项空白,对印度尼西亚森林资源信息管理系统的研究起到了开拓性的作用。目前,本系统现已应用于印度尼西亚西爪哇Parung Panjang林场,它能够帮助Parung Panjang林场的管理者提高管理水平,能有效、先进、科学地辅助决策者决策,有助于林场森林可持续规划的制定及顺利执行,同时,也为以后印度尼西亚森林资源信息管理的研究的奠定了基础,促进印度尼西亚数字林业的建设。

Carbon Characterization of Size-Segregated Particulate Matters (PMs) in Residential and Educational Areas in Padang City, Indonesia

引用

Journal of Geoscience and Environment Protection 2021年第8期9卷 225-238页

作者： Muhammad Amin Rahmi mulia Putri Fadjar Goembira Mitsuhiko Hata Masami Furuuchi Graduate School of Natural Science and Technology Kanazawa University Kanazawa Ishikawa Japan Department of Environmental Engineering Faculty of Engineering Andalas University Padang Sumatera Barat Indonesia Faculty of Geoscience and Civil Engineering Institute of Science and Engineering Kanazawa University Kanazawa Ishikawa Japan Faculty of Environmental Management Prince of Songkla University Hat Yai Songkhla Thailand

Size-segregated of particulate matter (PM) including PM0.1 at two different sites, i.e., educational (EA) and residential (RA) areas in Padang city, Indonesia were sampled by using a cascade type air sampler for 24 hours with the average flowrate 40 l/m throughout three weeks (March, 08th-25th 2018). Carbonaceous components were analyses by a carbon analyzer following the IMPROVE_TOR protocol. Average PM2.5 and PM10 concentrations in RA were higher than those in EA while being below the NAAQS of Indonesia. However, it was much higher compared to the WHO limit for 24 hours in RA. OC was the dominant fraction in TC. OC/EC ratio ranging from 2.4 to 33.0 was similar at both sites, suggesting the OC was emitted from various sources. Char-EC and soot-EC ratio were founded to be minimized for PM0.1 (0.40 ± 0.27 and 0.39 ± 0.39, respectively at each site), indicating a more influence of burning of fossil fuel as vehicles exhaust and coal combustion. The transboundary influence of open biomass burning was not so significant although it cannot be ignored.
