Preserving microbial diversity has become a strategic undertaking. Thus, ex situ microalgal culture conservation results in strategic and functional resource in both biodiversity protection and application domains. Cryopreservation of microalgae has been practiced since the 1960s and is now considered the optimal preservation strategy. Furthermore, the overall monitoring during growth of cultures after freezing/thawing protocols was hardly investigated and there is poor evaluation related to preserve especially the photosystem apparatus. The present study focuses on Stichococcus bacillaris as case study for short-term cryopreservation at −80 °C storage. Various freezing pretreatments using cryoprotective agents, and two thawing methods were compared introducing a novel variable to evaluate viability recovery and assessing growth kinetics of cultures immediately after thawing and after a series batch cultivation. Photosynthetic rate and pigments assessment were proposed to evaluate hidden metabolic cell damage. Results underline cryoprotective agents can increase the kinetic recovery of preserved cells in terms of reduction of lag phase during batch cultivation tests: the use of dimethyl sulfoxide and glycerol granted a growth comparable to unpreserved cells when sudden thawing occurs after 24 hours of storage, but recovery after preservation is less sensitive to cryoprotective agents when gradual thawing and 1 month of storage is considered. However, cells are always able to restore their physiological pathways even without agents, so their kinetic effect has been proved and quantified. Interestingly, both the photosynthetic efficiency and the ratio between total chlorophyll and carotenoids are comparable (0.75 Fv/Fm, 2.2 ± 0.25 g/g) to unpreserved cells and they are unsensitive to chosen agents, but the ratio between chlorophyll a and chlorophyll b was clearly altered (up to 10 times), suggesting that photoactive pigments relative proportions

The water scarcity in quality and quantity is becoming more noticeable and an urgent concern around the world. In Uruguay, these issues become exacerbated by the need to obtain drinking water in coastal areas, influenced by the climate change. Basic and structural geologies are strong conditioners in heterogeneous coastal aquifers. The objective of this study is to characterize the hydrochemistry of the fractured aquifers after having identified the main bearing fractures and the causes of aleatoreous water scarcity and quality problems, for hydric resources sustainable management. Identification of water bearing fracture, hydrogeochemical analysis and water quality evaluation are specific objectives. Some strategies were performed: 1) a base map in QGIS Software;2) fracture photointerpretation;3) geological correlation;4) statistical analysis of the background geochemistry data;5) ions analysis of strategically located wells. There were found water bearing fractures corresponding to 28 m3/h maximum flow rate for the NW-SE and 12 m3/h maximum flow rate for the NE-SW fracture direction, respectively. Besides, there could be a problem related to the high Sodium (Na) and Chloride (Cl) levels. In this respect, having previous data from 25 well samples, ions geochemical analysis has been carried out for 14 wells from Costa Azul and surrounding to have a first approach about the possible cause for the high values of Na (max. 385 mg/L) and Cl (max. 381 mg/L). The selected area for this study has a particular characteristic, because it corresponds to a heterogeneous fractured aquifer, which makes it difficult to catch water with enough flow rates and water quality to meet the population demand.

Treatment of Vulvovaginal Candidiasis with A Strategy Based on Phototherapy (M.A.C.^® Scar Acceleration Method)

引用

Modern Research in Inflammation 2024年第1期13卷 1-7页

Candidiasis, also known as candidiasis vulvovaginitis, is an infection caused by different types of Candida fungi, the most frequent being Candida albicans. The present study reports an effective strategy, which opens new avenues for the treatment of this public health problem. The MAC® Methodology, conventional laser light-emitting (LLLT)/LED) methods are based on the biphasic response demonstrated many times in LLLT research and as with other forms of drugs, a “drug” (irradiation parameters) and a “dose” (irradiation times) and the “Arndt-Schulz Law” is often cited as a suitable model to describe the dose-dependent effects of LLLT. This method uses photopharmaceuticals, cell markers and the use of correct parameters for each case to induce the acceleration of tissue repair. The present study shows a case of a 32-year-old patient diagnosed with recurrent candidiasis 4 years ago. Eighteen sessions were performed (every other day) using a photoactivated component (Methylene blue 1% + Clotrimazole 1%) and LED phototherapy (red, blue and violet) with emission times of 60 - 260 seconds for each applicator, according to the dose recommendations of the scar acceleration method (MAC®). At the sixth treatment session there was a noticeable decrease in the itching sensation reported by the patient. In session 11 she reported feeling a great improvement, indicating that she no longer felt itching in any area after 18 sessions. The present case demonstrates new methodologies to treat common problems in the population that have a positive impact on the quality of life. This methodology has a promising future because it is non-invasive and requires a great biological transformation for inflammatory, fungal and viral control.

冰川是南美洲阿根廷门多萨流域(33°S)重要的淡水资源,冰川作为气候变化的敏感指示器,对于理解和评估全球和区域气候变化具有重要意义。为了解门多萨流域冰川分布及变化趋势,探讨其对区域水资源和生态系统的影响,为应对气候变化提供科学依据,研究基于1990-2020年Landsat遥感影像,参考RGI冰川编目数据和阿根廷国家冰川清单,通过比值阈值法和人工解译法得到7期冰川边界,研究了门多萨流域冰川面积分布与变化特征。并结合TerraClimate气候数据,揭示了该区域在研究期间的气候变化趋势,探讨了区域气候变化对冰川变化的影响。结果表明:①2020年门多萨流域冰川面积为134.09±11.86 km^(2),1990-2020年冰川总体呈极显著波动下降趋势(p10 km^(2)占比最大,10 km^(2)规模冰川退缩速度最大;冰川主要分布在南坡,西北坡冰川最少,东南、东北坡冰川退缩速度最大;冰川主要分布在坡度5°~40°之间,50°~55°的冰川退缩速度最大;冰川主要分布在海拔4200~5400 m之间,<4000 m冰川退缩速率最大。③20世纪50年代末以来门多萨地区气温整体呈现极显著的上升趋势(p<0.001),研究区年均最高、最低气温每十年上升0.53、0.29℃。气温持续上升是门多萨流域冰川退缩的长期原因,降水变化是该区域冰川变化的短期原因。本研究为门多萨流域预防冰川变化导致的水资源可用性变化和地质灾害预防提供参考。

俯冲带中的流体可能对俯冲过程产生重要影响.然而,关于大陆俯冲期间流体规模及其作用的地球物理约束仍然有限.西阿尔卑斯造山带是全球保存最完好的大陆俯冲带之一,为认识大陆俯冲过程中流体作用的影响提供了重要的参考.本文综合多种地球物理方法分析了西阿尔卑斯造山带地区的V_(P)/V_(S)比值,发现在俯冲区的上盘侧存在高V_(P)/V_(S)(>1.9)带,与部分蛇纹岩化的上覆地幔楔位置一致;而在下盘侧存在异常低的V_(P)/V_(S)(<1.7)带,异常深度浅于30km.本文认为,观测到的低V_(P)/V_(S)比值异常是由地壳内广泛分布的富硅岩脉导致,指示了在俯冲时期大陆俯冲界面之上可能存在的富硅流体流动.本文的结果暗示俯冲时期的流体流动可能降低了俯冲界面的有效应力,从而促进了大陆俯冲.
