水分条件是限制西南岩溶地区植物恢复的重要生态因子。目前缺少季节性干旱过程中岩溶区植被恢复过程中主要植被群落水分利用特征差异的系统分析,限制了对岩溶区季节性干旱过程中植物的抗旱机制的理解。为了揭示重度干旱条件下典型岩溶区植被恢复过程中植物水分利用来源和效率,在桂林毛村岩溶生态试验场农田、草地、灌丛和林地等不同植被恢复过程中采集了主要的优势物种附近的0-100 cm深度土壤样品和8种植物茎杆、叶片样品,测定土壤水、植物茎秆水中氢氧同位素与植物叶片的碳同位素,利用贝叶斯同位素混合(MixSIAR)模型确定不同植被恢复阶段主要植物群落水分来源比例,分析水分利用来源和水分利用效率的差异。结果表明,1)重度干旱条件下,研究区除岩溶区灌丛阶段主要利用土壤水外,其他各植被恢复阶段的优势植物均主要利用地下河水。岩溶区农田、草丛、乔木和非岩溶区乔木林的优势物种对地下河水的利用率分别为61.7%±5.3%、70.0%±9.0%、61.5%±10.6%、57.9%±4.8%。而且除岩溶区灌丛阶段优势植物利用0-10 cm深度的土壤水的比例最大外,其他各植被恢复阶段和非岩溶区乔木林的优势植物利用60-100 cm深度的土壤水的比例最大,这与长期干旱表层土壤含水率较低有关。2)除灌丛阶段外,研究区岩溶区各植被恢复阶段优势植物水分利用效率均高于非岩溶区,其中,草丛阶段优势植物的水分利用效率最高,为56.5μmol·mol^(-1)。研究结果有助于理解重度干旱气候下岩溶区生态恢复过程中植物对环境变化的水文调控提供科学数据,为脆弱生态环境保护提供科技支撑。

The prevention of food contamination by pathogenic microorganisms is a very important factor for food safety and security during storage time. The essential oils have the potential to be used as antimicrobial agents, but their full potential is limited due to the sensitivity and volatility of bioactive compounds. This study aimed to characterize Thymus vulgaris essential oil, free and nano-encapsulated in alginate-whey protein concentrate carriers using the freeze-drying technique. GC/MS analysis was done to identify the oil composition. The investigation of the antimicrobial effect of free and encapsulated oil was performed on Escherichia coli, Staphylococcus aureus, and Candida albicans, by microdilution method. The free thyme oil exhibited antimicrobial activity against all tested microorganisms in the range of 0.71–1.43 mg/ml. Interestingly, encapsulated oil was more effective at lower concentrations (0.625–1.25 mg/ml), as a consequence of a nano-size carrier (0.25 ± 0.5 μm) together with other properties (encapsulation efficiency of 86.04%). TGA pointed out a significant effect of encapsulation, in comparison to free oil, on the stability of thyme oil at temperatures from 25 to 500 °C. The results indicated a high potential of thyme oil powder carriers as natural antimicrobial additives in food products.

Hypertension in adolescents is, as in other patients, one of the important cardiovascular risk factors, associated with hypertension in adults and with appearance of cardiovascular complications later in life. In recent years it is in increase, in parallel with occurrence of overweight in this age group. There is mostly essential or obesity-related hypertension. It is often asymptomatic, therefore it holds true also for adolescents, that it has to be actively searched, especially in risk groups such as overweight adolescents, adolescents with positive family history or some of the other classical cardiovascular risk factors. If we have normal-weight adolescent with important hypertension or symptomatic adolescent without positive family history, the possibility of secondary hypertension has to be thinking of and extended, on possible cause focused and stepwise diagnostics performed. In this case, the treatment is etiological. Otherwise, the first-line treatment in adolescents comprises nonpharmacological treatment measures. Sometimes, because of poor nonpharmacological treatment compliance and presence of hypertensive-target organ damage, antihypertensive medications have to be introduced. However, preventive actions represent the most important task, in the form of primary and primordial prevention. In this article, diagnostic approach, prevention and treatment strategies in adolescents are shortly presented.

文章基于广西2001年、2006年、2011年、2016年以及2020年的Landsat数据和土地利用数据，运用GIS方法构建石漠化转移矩阵、土地利用转移矩阵以及两者的交互矩阵以分析土地利用类型变化对石漠化等级的影响，并通过引入生境质量变化指数与贡献指数以评价土地利用转变对石漠化变化的影响。结果表明：（1）广西岩溶区石漠化与土地利用演变趋势均为动态改善趋势，石漠化在空间上呈现出“西重东轻、南重北轻”的特点，与耕地的“东西增、南北减”和林地的“东西减、南北增”的特点在空间分布上具有一定相关性；（2）研究区重度石漠化地区的草地转为林地对石漠化的改善最为显著；中度和轻度石漠化地区的耕地转为林地同样显示出显著的改善效果；潜在石漠化地区的灌丛转为林地对石漠化的改善效果最大；（3）基于生境质量变化指数与贡献指数评估土地利用变化对石漠化治理的成效，植被恢复是石漠化治理中的主要驱动力。根据生境质量贡献指数，研究区耕地转换为林地对石漠化治理的成效贡献最大，生境质量贡献指数为1.967；灌丛转换为林地、林地转换为灌丛的贡献分别排第二和第三，生境质量贡献指数分别为0.328和0.095；排名后三的均为其他土地利用类型转换为草地类型，耕地、林地及灌丛转换为草地，对应的生境质量贡献指数值分别为-0.0035、-0.0032以及-0.0006。
