#1
Xiaoqi Zhu, Feiya Chen, Huanfa Peng, Zhangyuan Chen
We propose and demonstrate a novel optical frequency comb (OFC) based microwave photonic filter which is able to realize arbitrary filtering shape with linear phase response. The shape of filter response is software programmable using finite impulse response (FIR) filter design method. By shaping the OFC spectrum using a programmable waveshaper, we can realize designed amplitude of FIR taps. Positive and negative sign of FIR taps are achieved by balanced photo-detection. The double sideband (DSB) modulation and symmetric distribution of filter taps are used to maintain the linear phase condition...

Importance: The Institute of Medicine and The Joint Commission recommend routine documentation of patients' sexual orientation in health care settings. Currently, very few health care systems collect these data since patient preferences and health care professionals' support regarding collection of data about patient sexual orientation are unknown. Objective: To identify the optimal patient-centered approach to collect sexual orientation data in the emergency department (ED) in the Emergency Department Query for Patient-Centered Approaches to Sexual Orientation and Gender Identity study...

Calcium alginate hydrogel is one of the most widely used biocompatible materials in biomedical and tissue engineering. This paper reports a hybrid 3D printing and electrodeposition approach to form the 3D calcium alginate hydrogel in a controllable manner. Firstly, a specific 3D printing system is developed by combining a 3D printer and a customized ejection syringe. Then, the mixed solution (1% w/v sodium alginate and 0.25% w/v CaCO3 nano particles) is filled in the syringe and ejected out from the nozzle to the substrate continuously...

Dendritic cell-specific ICAM-3 grabbing non-integrin (DC-SIGN) expressed on a variety of DCs, is a C-type lectin receptor that recognizes glycans on a diverse range of pathogens, including parasites. The interaction of DC-SIGN with pathogens triggers specific signaling events that modulate DC-maturation and activity and regulate T-cell activation by DCs. In this work we evaluate whether F. hepatica glycans can immune modulate DCs via DC-SIGN. We demonstrate that DC-SIGN interacts with F. hepatica glycoconjugates through mannose and fucose residues...

Multibacillary and paucibacillary paratuberculosis are both caused by Mycobacterium avium subspecies paratuberculosis. Multibacillary lesions are composed largely of infected epithelioid macrophages and paucibacillary lesions contain T cells but few bacteria. Multibacillary disease is similar to human lepromatous leprosy, with variable/high levels of antibody and a dysfunctional immune response. Animals with paucibacillary disease have high cell-mediated immunity and variable levels of antibody. This study aims to characterize the immunological dysfunction using TruSeq analysis of the ileocaecal lymph node that drains disease lesions...

For graphene (a Dirac material) it has been theoretically predicted and experimentally observed that DC resistivity is proportional to $ T^4$ when the temperature is much less than Bloch-Gr\"{u}neisen temperature ($\Theta_{BG}$) and T-linear in opposite case ($T\gg\Theta_{BG}$). Going beyond this case, we investigate the dynamical electrical conductivity in graphene using the powerful methods the memory function formalism. In the zero frequency regime, we obtain the above mentioned behavior which was previously obtained using the Bloch-Boltzmann kinetic equation...

Malignant gliomas (MG), tumors of glial origin, are the most commonly diagnosed primary intracranial malignancies in adults. Currently available treatments have provided only modest improvements in overall survival and remain limited by inevitable local recurrence, necessitating exploration of novel therapies. Among approaches being investigated, one of the leading contenders is immunotherapy, which aims to modulate immune pathways to stimulate the selective destruction of malignant cells. Dendritic cells (DCs) are potent initiators of adaptive immune responses and therefore crucial players in the development and success of immunotherapy...

BACKGROUND: Enzymatically modified low density lipoprotein (eLDL), C reactive protein (CRP), dendritic cells (DCs), and T cells were shown to be involved in the pathogenesis of atherosclerosis. This study aimed to investigate whether eLDL and CRP could cooperatively promote DC-mediated T cell activation and proliferation. METHOD: Low density lipoprotein was isolated from healthy human plasma and treated with proteases and cholesterol esterase. CD14(+) monocytes were isolated from human peripheral blood by gradient centrifugation and enriched with CD14 Microbeads, which were then induced with recombinant human IL-4 and granulocyte-macrophage colony-stimulating factor before treated with eLDL and/or CRP...

A systematic search for carbon-chain cumulenones beyond H2C4O has been undertaken using microwave spectral taxonomy in combination with a pulsed jet discharge source. No evidence was found for the C2υ isomer of H2C5O or its longer derivatives, but HC(O)C4H, the longer variant of propynal, HC(O)CCH, was identified instead. Its rotational and leading centrifugal distortion constants have been derived to high accuracy from detection of both a- and b-type lines; those below 40 GHz were measured using a Fabry-Perot cavity, while lines between 40 and 72 GHz were recorded by double resonance techniques...

We have measured the third-order permittivity spectra ε3(3) of a monocationic and of a dicationic liquid close to the glass transition temperature by applying ac electric fields with large amplitudes up to 180 kV/cm. A peak ("hump") in the modulus of ε3(3) is observed for a mono-cationic liquid after subtraction of the dc contribution from the imaginary part of ε3(3). We show that the origin of this experimental "hump" is a peak in the imaginary part of ε3(3), with the peak height strongly increasing with decreasing temperature...

We present a portable system for personalized blood cell counting consisting of a microfluidic impedance cytometer and portable analog readout electronics, feeding into an analog-to-digital converter (ADC), and being transmitted via Bluetooth to a user-accessible mobile application. We fabricated a microfluidic impedance cytometer with a novel portable analog readout. The novel design of the analog readout, which consists of a lock-in-amplifier followed by a high-pass filter stage for subtraction of drift and DC offset, and a post-subtraction high gain stage, enables detection of particles and cells as small as 1 μm in diameter, despite using a low-end 8-bit ADC...
