    Abstract Bortezomib (BTZ), a proteasome inhibitor, is a promising therapeutic option for multiple myeloma (MM) patients. However, drug resistance often occurs, leading to disease relapse and poor prognosis. In this study, we aimed to identify novel genes associated with drug resistance and investigate their roles in BTZ resistance. Through the screening of 26 genes frequently associated with chemosensitivity or drug resistance, we discovered that KDM4C, a histone demethylase, exhibited increased expression in BTZ-resistant MM cells compared to their sensitive counterparts. Overexpression of

    Abstract Optical parameter estimation based on the data obtained by coherent optical receivers is critical for optical performance monitoring (OPM) and the stable operation of the receiver digital signal processing (DSP). A robust multi-parameter estimation is intricate due to the interference of various system effects. By resorting to the cyclostationary theory, we are able to formulate a chromatic dispersion (CD), frequency offset (FO), and optical signal-to-noise ratio (OSNR) joint estimation strategy that is resistant to the random polarization effect, including polarization mode dispersion (PMD) and polarization rotation. The method uses data directly after the DSP resampling and matched filtering. Both numerical simulation and field optical cable experiment validate our method.

    Abstract Quantifying hemoglobin is vital yet invasive through blood draws. We developed a wearable diffuse reflectance spectroscopy device comprising control and sensor boards with photodiodes and light-emitting diodes to noninvasively determine hemoglobin. Neural networks enabled recovery of optical parameters for chromophore fitting to calculate hemoglobin. Testing healthy and elderly subjects revealed strong correlation (r=0.9) between our system and invasive methods after data conversion. Bland-Altman analysis demonstrated tight 95% limits of agreement from -1.98 to 1.98 g/dL between the DRS and invasive hemoglobin concentrations. By spectroscopically isolating hemoglobin absorption, interference from melanin was overcome. Our device has the potential for future integration into wearable technology, enabling hemoglobin level tracking.

    Abstract Biologists have long known that animal population dynamics are regulated by a combination of bottom-up (resource availability) and top-down forces (predation). Yet, economists have argued that human population dynamics can also be influenced by intraspecific cooperation. Despite awareness of the role of interspecific cooperation (mutualism) in influencing resource availability and animal population dynamics, the role of intraspecific cooperation (sociality) under different environmental conditions has rarely been considered. Here we examine the role of what we call "lateral forces" that act within populations and interact with external top-down and bottom-up forces in influencing population dynamics using an individual-based model linking environmental quality, intraspecific cooperation, and population size. We find that the proportion of cooperators is higher when the environment is poor and population sizes are greatest under intermediate resources levels due to the contrasting effects of resource availability on behavior and population size. We also show that social populations are more resilient to environmental change than non-social ones because the benefits of intraspecific cooperation can outweigh the effects of constrained resource availability. Our study elucidates the complex relationship between environmental harshness, cooperation, and population dynamics, which is important for understanding the ecological consequences of cooperation.

    Abstract Fluorescence-encoded microbeads (FEBs) have been widely used as a critical component in multiplexed biomolecular assays. Here, we propose a simple, sustainable, low-cost, and safe strategy for preparing FEBs by assembling fluorescent proteins (FPs) onto magnetic microbeads (MBs) via chemical coupling. Combining the type of FP, the concentration of FP, and the size of the magnetic microbeads as encoding elements, an ultralarge encoding capacity with 506 barcodes was obtained. We demonstrate that the FP-based FEBs have good stability during long-term storage and tolerate the use of an organic solution. Multiplex detection of femtomolar ssDNA molecules was achieved via flow cytometry, and the detection procedure is simple and fast because it does not require amplification and washing strategies. The advantages of this advanced method for multiplex detections including high sensitivity, specificity, accuracy, repeatability, rapidity, and cost-effectiveness show a broad application prospect in basic and applied research fields such as disease diagnosis, food safety, environmental protection, proteomics, genomics, and drug screening.

    Abstract Bovine herpes virus -1 (BoHV-1) infection leads to upper respiratory tract infection, conjunctivitis and genital disorders in cattle. To control BoHV-1, it is important to understand the role of viral proteins in viral infection. BoHV-1 has several gene products to help in viral replication in infected cell. One such gene is deoxyuridine triphosphate nucleotidohydrolase (dUTPase) also known as UL50. In this study, we analyzed the amino acid sequence of UL50 (dUTPase) using bioinformatics tools and found that it was highly conserved among herpesvirus family. Then, it was cloned and expressed in Escherichia coli Rosetta (DE3), induced by isopropy1-b-D-thiogalactopyranoside (IPTG) and the recombinant UL50 protein was purified to immunize rabbits for the preparation of polyclonal antiserum. The results indicated that the UL50 gene of BoHV-1 was composed of 978 nucleotides, which encoded 323 amino acids. Western blot analysis revealed that polyclonal sera against UL50 reacted with a band of 34 kDa. Furthermore, immunofluorescence assay showed that UL50 localized in the cytoplasmic area. Taken together, UL50 was successfully cloned, expressed and detected in BoHV-1-infected cells and was localized in the cytoplasm to help in the replication of BoHV-1 in infected cells.
