Part northern Henan Province, China taken as area, and cycle divided into five periods (seeding-tillering, overwintering, reviving, jointing-heading, flowering-maturing) based on monitoring obtained from agrometeorological stations. With help Google Earth Engine (GEE) platform, separability between other land cover types analyzed...

Traffic-related air pollution especially in highly socioeconomically developed megacity is usually considered as a severe problem leading to inevitable adverse health outcomes. This study aimed investigate the associations between traffic-related pollutants with risk of dry eye disease (DED) outpatient visits (Guangzhou) along subtropical coast South China. Daily data on DED and environmental variables from 1 January 2014 31 December 2020 Guangzhou were obtained. A time-series using...

Genotoxic stress such as ionizing radiation halts entry into mitosis by activation of the G(2) DNA damage checkpoint. The CHK1 inhibitor 7-hydroxystaurosporine (UCN-01) can bypass checkpoint and induce unscheduled in irradiated cells. Precisely, how cells behave following abrogation remains to be defined. In this study, we tracked fates individual after abrogation, focusing particular on whether they undergo mitotic catastrophe. Surprisingly, while a subset UCN-01-treated were immediately...

This study explored the environmental determinants of different months on snail density measured in April at types habitats (marshlands, inner embankments, and hills) by considering spatial effects. Data were gathered from surveys snails that conducted Hunan Province 2016, information was collected variables. To investigate factors influencing various habitats, ordinary least square model, lag error model all used. The for showed effects three habitats. In marshlands, associated positively...

To acquire phosphorus, cyanobacteria use the typical bacterial ABC-type phosphate transporter, which is composed of a periplasmic high-affinity phosphate-binding protein PstS and channel formed by two transmembrane proteins PstC PstA. A putative pstS gene was identified in genomes cyanophages that infect unicellular marine Prochlorococcus Synechococcus. However, it has not been determined whether cyanophage functional during infection to enhance uptake rate host cells. Here we showed P-SSM2...

Abstract The G2 DNA damage checkpoint is activated by genotoxic agents and particularly important for cancer therapies. Overriding the can trigger precocious entry into mitosis, causing cells to undergo mitotic catastrophe. But some checkpoint-abrogated remain viable progress G1 phase, which may contribute further genome instability. Our previous studies reveal that effectiveness of spindle assembly duration mitosis are pivotal determinants catastrophe after abrogation. In this study, we...

Emerging evidence has highlighted the possible links of environmental pollution with several cardiovascular diseases (CVDs). The current study aimed to explore impact short-term air exposure on CHD hospitalization in Hefei.Data about daily number admissions (from 2014 2021) were retrieved from First Affiliated Hospital Anhui Medical University. Air pollutants and meteorological data obtained China Environmental Monitoring Station Meteorological Data Service Center, respectively. correlation...

Summary Viral infection of marine phytoplankton releases a variety dissolved organic matter (DOM). The impact viral DOM (vDOM) on the uninfected co‐occurring remains largely unknown. Here, we conducted transcriptomic analyses to study effects vDOM cyanobacterium Prochlorococcus , which is most abundant photosynthetic organism Earth. Using MIT9313, showed that its growth was not affected by vDOM, but many tRNAs increased in abundance. We tested tRNA‐gly and found abundance upon addition...

Abstract Cyanopodoviruses affect the mortality and population dynamics of unicellular picocyanobacteria Prochlorococcus Synechococcus, dominant primary producers in oceans. Known cyanopodoviruses all contain DNA polymerase gene (DNA pol) that is important for phage replication widely used field quantification diversity studies. However, we isolated 18 without identifiable pol. They form a new MPP-C clade was separated from existing MPP-A, MPP-B, P-RSP2 clades. The phages have smallest...

Snail abundance varies spatially and temporally. Few studies have elucidated the different effects of determinants affecting snail density between upstream downstream areas Three Gorges Dam (TGD). We therefore investigated differential drivers changes in these areas, as well spatial-temporal changes.A survey was conducted at 200 sites over a 5-year period to monitor dynamic within Yangtze River basin. Data on corresponding variables that might affect abundance, such meteorology, vegetation,...

The eutrophic lake Dianchi, china, is a hotspot for methane (CH4) and nitrous oxide (N2O) emissions. However, the potential factors driving CH4 N2O production in riparian wetlands of Dianchi Lake remain unclear. In current study, was evaluated using incubation experiments. abundance community structure methanogenic communities denitrifying bacteria were measured quantitative polymerase chain reaction Illumina MiSeq sequencing. results indicated that differed significantly among Lake, with...

This paper studies the effects of time delay spread on TCM in portable radio environments. The average irreducible bit error rate (BER) three different schemes are evaluated by simulation. results under low indicate that performance with interleaving/deinterleaving is much better than QPSK and good flat fading also give performance. A scheme frequency-selective channel should have both large Euclidean distance degree built-in diversity. If relatively high, they do not advantages over QPSK....

The long-term global Leaf Area Index (LAI) products are critical supports for characterizing the changes in land surface and its interactions with other components of Earth system under dramatic change. However, intercomparisons between current available LAI present significant spatiotemporal inconsistencies which have been a persistent source uncertainties change ecology. Yet, direct systematic evaluation is still lacking due to absence appropriate references, especially before 2000. Here,...

Rotifers are crucial for the monitoring of aquatic ecosystems because sensitive response rotifer community structure to environmental changes. Comparisons and combinations meta-barcoding (sequence analysis) traditional morphological identification responses rare. To better understand differences between two approaches, we conducted a study using 48 mesocosms (2500 L) combination warming, nutrient loading, pesticide evaluate applicability both methods communities in order how respond multiple...

Abstract To acquire phosphorus, cyanobacteria use the typical bacterial ABC-type phosphate transporter, which is composed of a periplasmic high-affinity phosphate-binding protein PstS and channel formed by two transmembrane proteins PstC PstA. The pstS gene has been identified in genomes cyanophages that infect unicellular Prochlorococcus Synechococcus . However, it unknown how cyanophage interplays with host PstA to function as chimeric ABC transporter. Here we showed P-SSM2 was abundant...

Abstract Most living organisms exhibit diurnal rhythms as an adaptation to the daily light-dark (diel) cycle. However, have not been found in viruses. Here, we studied diel infection patterns of bacteriophages infecting unicellular cyanobacteria Prochlorococcus and Synechococcus , which are most abundant photosynthetic oceans. With lab cultures, that cyanophages used three strategies dark: no adsorption, adsorption but replication, replication. Interestingly, former two exhibited rhythmic...
