Glycosylation Heterogeneity of Hyperglycosylated Recombinant Human Interferon‑β (rhIFN-β)
We previously developed a biobetter
version of rhIFN-β (R27T)
that possesses an additional glycosylation site compared with rhIFN-β
1a. Herein, we characterized N-glycosylation heterogeneity of R27T,
which includes both N-glycan site occupancy heterogeneity (macro-heterogeneity)
and complexity of carbohydrate moieties (micro-heterogeneity). N-glycan
site occupancy manifested as distinct differences in size and isoelectric
point. The analysis of complex carbohydrate moieties of R27T involved
the common biopharmaceutical glycosylation critical quality attributes
such as core fucosylation, antennary composition, sialylation, N-acetyllactosamine extensions, linkages, and overall glycan
profiles using weak anion-exchange and hydrophilic interaction high-performance
liquid chromatography with 2-aminobenzoic acid-labeled N-glycans.
The double-glycosylated form accounted for approx. 94% R27T, while
the single-glycosylated form accounted for 6% R27T. N-glycans consisted
of a mixture of bi-, tri-, and tetra-antennary glycans, some with N-acetyllactosamine extensions, but neither outer arm fucose
nor α-galactose was detected. Sialic acid major variants, N-acetyl- and N-glycolyl-neuraminic acid,
were more abundant in R27T than in Rebif. The major N-glycan, accounting
for ∼42% of total N-glycans, had a di-sialylated, core-fucosylated
bi-antennary structure

Table_1_Clinical outcomes following robotic versus conventional DIEP flap in breast reconstruction: A retrospective matched study.docx
BackgroundA robotic deep inferior epigastric perforator (DIEP) flap created through a totally extraperitoneal approach minimizes violation of the donor site, which may lead to postoperative pain reduction and rapid recovery. The authors compared the clinical outcomes of robotic and conventional DIEP flap breast reconstructions.MethodsData from consecutive patients who underwent mastectomy with DIEP flaps for breast reconstruction between July 2017 and January 2021 were retrospectively reviewed. Patients were divided into robotic and conventional DIEP groups, and the two groups were matched using the inverse probability of treatment weighting method. They were compared based on the reconstruction time, drainage amount, postoperative pain, rescue analgesics, hospital stay, complications, and BREAST-Q scores.ResultsAfter matching, a dataset of 207 patients was formed, including 21 patients in the robotic DIEP group and 186 patients in the conventional DIEP group. The mean reconstruction time was longer in the robotic DIEP group than in the conventional DIEP group (PConclusionsThis study suggests that a robotic DIEP flap offers enhanced postoperative recovery, accompanied by a reduction in postoperative pain and hospital stay.</p

Gate-Tunable Multiband van der Waals Photodetector and Polarization Sensor
A single
photodetector with tunable detection wavelengths and polarization
sensitivity can potentially be harnessed for diverse optical applications
ranging from imaging and sensing to telecommunications. Such a device
will require the combination of multiple material systems with different
structures, band gaps, and photoelectrical responses, which is extremely
difficult to engineer using traditional epitaxial films. Here, we
develop a multifunctional and high-performance photosensor using all
van der Waals materials. The device features a gate-tunable spectral
response that is switchable between near-infrared/visible and short-/midwave
infrared, as well as broad-band operation, at room temperature. The
linear polarization sensitivity in the telecommunication O-band can
also be directly modulated between horizontal, vertical, and nonpolarizing
modes. These effects originate from the balance of photocurrent generation
in two of the active layers that can be manipulated by an electric
field. The photodetector features high detectivity (>109 cmHz1/2W–1) together with fast operation
speed (∼1 MHz) and can be further exploited for dual visible
and infrared imaging
High-Performance Mid-IR to Deep-UV van der Waals Photodetectors Capable of Local Spectroscopy at Room Temperature
The ability to perform broadband
optical spectroscopy with subdiffraction-limit
resolution is highly sought-after for a wide range of critical applications.
However, sophisticated near-field techniques are currently required
to achieve this goal. We bypass this challenge by demonstrating an
extremely broadband photodetector based on a two-dimensional (2D)
van der Waals heterostructure that is sensitive to light across over
a decade in energy from the mid-infrared (MIR) to deep-ultraviolet
(DUV) at room temperature. The devices feature high detectivity (>109 cm Hz1/2 W–1) together with
high bandwidth (2.1 MHz). The active area can be further miniaturized
to submicron dimensions, far below the diffraction limit for the longest
detectable wavelength of 4.1 μm, enabling such devices for facile
measurements of local optical properties on atomic-layer-thickness
samples placed in close proximity. This work can lead to the development
of low-cost and high-throughput photosensors for hyperspectral imaging
at the nanoscale
