甘蔗收获后蔗糖分降低是蔗糖加工单位的主要问题之一,特别是那些在高温下持续压榨的地区。通过研究评估榨季后期甘蔗收获后蔗糖分的损失量及其与酸性转化酶和葡聚糖蔗糖酶活性的关系,结果表明,甘蔗收获后,随着这两种酶活性的上升,甘蔗的商品蔗糖急剧下降。刚收获的甘蔗商品蔗糖值为10.88,在收获48、240h后,则分别降低2.27、6.59个单位,10d后蔗糖分降低约60%。对收获的甘蔗淋水并覆盖蔗叶,其蔗糖分降低约44%,而经化学物质处理并覆盖蔗叶的甘蔗蔗糖分减少27%。在甘蔗贮放期间,其蔗糖酸性转化酶和葡聚糖蔗糖酶活性明显增加。经化学处理并覆盖蔗叶后,收获甘蔗的两种酶活性明显下降。研究结果还表明,通过应用抗菌和抗转化化学物质配方具有使后期收获的甘蔗蔗糖分降低到最小的可能性。

Alzheimer’s disease(AD)is the most common neurodegenerative disorder characterized by slow and progressive decline of cognitive and memory *** only approximately 5%of the cases,AD is familial,as often predisposed by genetic mutations(Hoogmartens et al.,2021),while sporadic AD accounts for approximately 95%of the *** amyloid cascade hypothesis is one of the fundamental hypotheses put out to explain AD pathogenesis as dysregulated homeostasis of amyloid-β(Aβ)peptides that leads to the accumulation of Aβplaques in the parenchyma,an anatomical hallmark of AD.

Climate change is ranked as one of the most severe threats to global biodiversity. This global phenomenon is particularly true for reptiles whose biology and ecology are closely linked to climate. In this study, we used over 1,300 independent occurrence points and different climate change emission scenarios to evaluate the potential risk of changing climatic conditions on the current and future potential distribution of a rock-dwelling lizard; the velvet gecko. Furthermore, we investigated if the current extent of protected area networks in Australia captures the full range distribution of this species currently and in the future. Our results show that climate change projections for the year 2075 have the potential to alter the distribution of the velvet gecko in southeastern Australia. specifically, climate change may favor the range expansion of this species to encompass more suitable habitats. The trend of range expansion was qualitatively similar across the different cli- mate change scenarios used. Additionally, we observed that the current network of protected areas in southeast Australia does not fully account for the full range distribution of this species currently and in the future. Ongoing climate change may profoundly affect the potential range distribution of the velvet gecko population. Therefore, the restricted habitat of the velvet geckos should be the focus of intensive pre-emptive management efforts. This management prioritization should be extended to encompass the increases in suitable habitats observed in this study in order to maximize the microhabitats available for the survival of this species.
