3D‐Printed Unibody Microfluidic Devices for Organ‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A practical approach is demonstrated to 3D printing unibody microfluidic Organ‐on‐Chip (OoC) devices using commercial resins and desktop DLP printers. The demonstrated functional devices support 2D monolayers, 3D spheroids, and barrier tissues. With optimised design and post‐processing techniques, leak‐free, biocompatible microchannels and membranes ...

NUCLEAR RNA POLYMERASE D1 is essential for tomato embryogenesis and desiccation tolerance in seeds

open access: yesCell Reports
Summary: Plant-unique RNA polymerase IV (RNA Pol IV) governs the establishment of small RNA (sRNA)-directed DNA methylation (RdDM). In dicotyledon, elevated RdDM activity is often associated with embryogenesis; however, the loss of RdDM frequently ...

Nanomaterial‐Based Optical Biosensors for SARS‐CoV‐2 Detection: A Retrospective of the Pandemic

open access: yesAdvanced Sensor Research, EarlyView.
This review discusses nanomaterial‐based optical biosensors developed for or adapted to the detection of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). It concludes by providing a perspective on how lessons learned during the coronavirus disease of 2019 (COVID‐19) pandemic may be applied for future research on nanomaterial‐based ...

SMYD3 Promotes Immune Evasion in Clear Cell Renal Cell Carcinoma via SREBP1‐Mediated Transactivation of CD47

open access: yesAdvanced Science, EarlyView.
Cancer cell‐intrinsic SMYD3 orchestrates an immunosuppressive microenvironment and impairs the response to PD‐1 blockade by reprogramming immune cells landscape in the tumor microenvironment of clear cell renal cell carcinoma (ccRCC). The immunomodulatory function of SMYD3 is mediated via the SREBP1/CD47 pathway.

Inhibiting the oligomerization of mycobacterial DNA-directed RNA polymerase (RNAP) using natural compound via in-silico techniques

open access: yesMedicine in Novel Technology and Devices
Mycobacterium tuberculosis (Mtb) is responsible for the spread of tuberculosis (TB). The current study employed virtual screening of 2569 natural compounds against the DNA-directed RNA polymerase (RNAP) of Mtb to identify the possible binders that can ...
