Drought stress affects plant growth and causes significant issues in meeting global demand for food crops and fodder.Drought can cause physiological,physicochemical,and morphological changes in plants,which negatively affects plant growth and productivity.To combat this under the increasing global threat of water shortage and rapid population expansion,it is crucial to develop strategies to meet global food demands.Plant growth-promoting rhizobacteria(PGPR)may provide a safe solution to enhancing crop yields through various mechanisms.These soil bacteria can provide drought tolerance to crop plants,allowing them to survive and thrive in water-scarce conditions.Productions of phytohormones,free radical-scavenging enzymes,and stress-combating enzymes that can increase tolerance to drought-induced stress are key features of plant-associated microbial communities.This review summarizes the beneficial properties of microbes that help plants tolerate water scarcity and highlights the bacterial mechanisms that enhance drought tolerance in plants.

Ovarian cancer(OC)is one of the most common and fatal types of gynecological cancer.OC is usually detected at the advanced stages of the disease,making it highly lethal.miRNAs are single-stranded,small non-coding RNAs with an approximate size ranging around 22 nt.Interestingly,a considerable proportion of miRNAs are organized in clusters with miRNA genes placed adjacent to one another,getting transcribed together to result in miRNA clusters(MCs).MCs comprise two or more miRNAs that follow the same orientation during transcription.Abnormal expression of the miRNA cluster has been identified as one of the key drivers in OC.MC exists both as tumor-suppressive and oncogenic clusters and has a significant role in OC pathogenesis by facilitating cancer cells to acquire various hallmarks.The present review summarizes the regulation and biological function of MCs in OC.The review also highlights the utility of abnormally expressed MCs in the clinical management of OC.

LC射频振荡器的简化设计

引用

移动通信 1975年第2期 58-62页

作者： wunnava Subbarao 謝振海

用物理方法简化复杂的数学运算并确定稳定度与频率设计射频振荡器时,繁杂的数学运算必须简化。用物理方法简化数学运算后,便能更清楚地表明:元件参数的变化对振荡稳定度、负载效应和振荡条件等的影响。
