Abstract	Speckle reduction is a crucial technique since the presence of speckle disturbs the quality of the reconstruction in digital holography. In this paper, we present an easy, fast, and efficient single-shot method to reduce speckle noise in digital holography. The method reconstructs subholograms from a single hologram. Then, sub-reconstruction images are randomly shuffled and divided into several groups and low-dimensional noise-reduced images can be achieved by averaging sub-reconstruction image groups by groups. Next, these low-dimensional noise-reduced images are combined to obtain a noise-reduced image. Finally, the noise-reduced image is processed by a mean filter to obtain a final image, which has substantially less speckle noise while preserving the dimensions of the original image. The experimental results demonstrate the effectiveness of the proposed method and indicate its potential in real-time digital holography.

Abstract	Objective: To establish an optimized autologous mitochondria transport technique for oocyte-aging rescue, which minimizes both the patient's pains and the damage to oocytes. Design: Experimental laboratory study. Setting: Laboratory. Animal(s): Institute of Cancer Research mice. Intervention(s): The murine umbilical cord mesenchymal stem cells were isolated from the female pup and cryopreserved. After the female aged, its germinal vesicle (GV) oocytes were collected and treated to weaken the zona pellucida. Its autologous umbilical cord mesenchymal stem cells were induced into granulosa cells (iGCs). The zona-weakened GV oocytes were aggregated with iGCs into iGC-oocyte complexes. Then, these complexes were cultured in growth-differentiation factor 9-containing media for 3 days. Next, they were subjected to in vitro maturation and fertilization. Presumptive zygotes were cultured for 24 hours, and the cleaved 2-cell embryos were selected for embryo transfer. Main outcome measure(s): The oocyte quality was determined by examining mitochondrial ultrastructure using transmission electron microscopy, the adenosine triphosphate content using a luminometer, and intracellular reactive oxygen species levels by confocal microscopy. The spindle organization in mature oocytes was examined by confocal microscopy. The developmental potential of oocytes was evaluated by monitoring the in vitro embryo development and the birth rate after embryo transfer. Result(s): Mitochondria migrated from iGCs into the GV oocyte via transzonal filopodia. The maturation rate, quality, and developmental potential of these oocytes were substantially increased. Furthermore, the birth rate after embryo transfer has been improved. Conclusion(s): This approach used noninvasive procedures to collect mitochondria donor cells and optimized mitochondria transfer manipulations; thus, it may have potential in ameliorating oocyte-aging-related subfertility.

Abstract	In digital holography, the phase is most important, and the quality of the reconstructed phase determines the final reconstructed image effect. However, noise is inevitably introduced in the process of recording the hologram. For regions without object light, the phase has a random distribution, which affects the final phase quality. This kind of noise is called abnormal phase fluctuations in this paper. The correlation between amplitude and phase in digital holography is used to judge whether there is useful phase information. Through structural similarity and the light-dark relationship, a credible probability mask is introduced to extract the phase that needs to be preserved. The simulation and experimental results show that abnormal phase fluctuations are successfully removed, and the useful phase information is retained.

Abstract	In brief: During the morula to blastocyst transformation, polarity establishment in outer cells is a prerequisite for trophectoderm lineage specification. This study reveals the roles of polarity proteins PATJ and MPDZ in trophectoderm lineage fate decision. Abstract: In mouse preimplantation embryos, cell polarity plays a crucial role in the first lineage specification. PATJ and its homolog MPDZ are the main members of CRB-PALS1-PATJ (CRUMBS-Protein associated with Lin7 1-Pals-associated tight junction protein) apical polarity complex. They act as adaptor proteins connecting CRB-PALS1 and tight junction proteins, making them essential for cell polarization and stabilization of apical junctions. However, their roles in regulating trophectoderm differentiation and blastocyst development remain unclear. In this study, PATJ and/or MPDZ were downregulated by the microinjection of specific RNA interference constructs into zygotes. Downregulation of PATJ alone did not severely affect early embryonic development and trophectoderm lineage differentiation although it slowed down the blastocyst formation. Depletion of PATJ and MPDZ did not affect compaction and morula development but impaired blastocyst formation. Furthermore, the expression of trophectoderm-specific transcription factors and trophoblast differentiation was compromised in the absence of PATJ/MPDZ. These abnormalities might result from the breakdown of apical domain in the outer cells of the embryo. The loss of PATJ/MPDZ caused the breakdown of CRB and PAR polarity complexes as well as deficiencies in tight junctions and actin filaments. These defects led to ectopic activation of Hippo signaling in the outer cells of developing embryos, ultimately suppressing Cdx2 expression and trophectoderm differentiation. Altogether, PATJ and MPDZ are essential for trophectoderm lineage differentiation and normal blastocyst morphogenesis via the regulation of the establishment of apical domain, formation of tight junctions, phosphorylation and localization of YAP, and expression of trophectoderm-specific transcription factors.

Abstract	Speckle reduction is a crucial technique, since the presence of speckle disturbs the quality of the reconstruction in digital holography. In this paper, we present a redundant speckle elimination method to suppress the speckle noise. For the same position in each of the reconstructed sub-images, we consider pixels with the same gray value as information with the same speckle distribution. Therefore, a speckle-suppressed gray value can be obtained by extracting pixels with different gray values and then averaging. Through theoretical analysis and experiments, we demonstrate that speckle contrast can be decreased significantly by using the proposed method. Moreover, we show that the despeckle strength of the proposed method highly depends on the number of binary masks. These results indicate the potential of the proposed method for various applications.

Abstract	Phyllosphere and rhizosphere are unique and wide-ranging habitats that harbor various microbial communities, which influence plant growth and health, and the productivity of the ecosystems. In this study, we characterized the shared microbiome of the phyllosphere and rhizosphere among three plants (Ipomoea pes-caprae, Wedelia chinensis, and Cocos nucifera), to obtain an insight into the relationships between bacteria (including diazotrophic bacteria) and fungi, present on these host plants. Quantitative PCR showed that the abundances of the microbiome in the soil samples were significantly higher than those in the phyllosphere samples, though there was an extremely low abundance of fungi in bulk soil. High-throughput sequencing showed that the alpha-diversity of bacteria and fungi was higher in the rhizosphere than the phyllosphere samples associated with the same plant, while there was no obvious shift in the alpha-diversity of diazotrophic communities between all the tested phyllosphere and soil samples. Results of the microbial composition showed that sample-specific bacteria and fungi were found among the phyllosphere and rhizosphere of the different host plants. About 10%-27% of bacteria, including diazotrophs, and fungi overlapped between the phyllosphere and the rhizosphere of these host plants. No significant difference in microbial community structure was found among the tested rhizosphere samples, and soil properties had a higher influence on the soil microbial community structures than the host plant species.

Abstract	Roundup is a widely used glyphosate-based herbicide worldwide. Roundup residues can be detected in the organs and urine of animals. However, its toxicity on mammalian preimplantation embryos has not been well investigated. Here, we show Roundup impairs the development and quality of bovine preimplantation embryos in a dose-dependent manner. Exposure to the agricultural recommended doses of Roundup caused in vitro developmental arrest and quick death of bovine embryos. Furthermore, even a very low concentration (0.9 ppm) of Roundup was harmful to bovine preimplantation development. In addition, Roundup increases intracellular calcium levels and induces oxidative stress and apoptosis in bovine embryos. Even if the embryos developed to morphologically normal blastocysts when cultured with low concentrations of Roundup, abnormal intracellular calcium and oxidative stress could be detected inside the embryos and led to an increased incidence of apoptosis in the blastocysts. These data suggest Roundup residues from the agricultural application are potentially dangerous to mammalian preimplantation embryos.

Abstract	Abscisic acid (ABA), as one of the foremost signaling molecules in plants, is an important hormone which plays versatile functions in regulating developmental process and adaptive stress process. A set of introgression lines were previously generated via a backcrossing program using an elite indica cultivar rice Teqing (O. sativa L.) as recipient and an accession of Yuanjiang common wild rice (O. rufipogon Griff.) as donor. In this study, the previously developed introgression lines were evaluated for ABA sensitivity. Here we reported that a total of 14 quantitative trait loci (QTLs) associated with ABA sensitivity were identified. An ABA sensitive introgression line, YIL53, was identified and characterized. Physiological characterization, including chlorophyll content, malondialdehyde content, soluble sugar content, and stomata movement, demonstrated that YIL53 exhibited the characteristics associated with ABA sensitivity. Genotypic analysis revealed that YIL53 harbored one QTL related to ABA sensitivity, qASS1-2, which was located on chromosome 1 within one introgressed segment derived from the Yuanjiang common wild rice. Furthermore, the qASS1-2 was finally narrowed down to a 441-kb region between simple sequence repeats (SSR) marker RM212 and single nucleotide polymorphism (SNP) marker M3 using the segregation population derived from the cross between Teqing and YIL53, and three candidate genes associated with ABA sensitivity were identified using a strategy combined gene expression analysis with QTL mapping. Identification of the QTLs related to ABA sensitivity and characterization of the ABA sensitive line YIL53 would provide a helpful basis for isolating novel genes related to ABA sensitivity.

Abstract	The surfaces of a leaf are unique and wide habitats for a microbial community. These microorganisms play a key role in plant growth and adaptation to adverse conditions, such as producing growth factors to promote plant growth and inhibiting pathogens to protect host plants. The composition of microbial communities very greatly amongst different plant species, yet there is little data on the composition of the microbiome of the host plants on the coral island in the South China Sea. In this study, we investigated the abundances and members of a major microbial community (fungi, bacteria, and diazotrophs) on the leaves of five dominant plant species (
