Human cytomegalovirus gH/gL/gO binding to PDGFRα provides a regulatory signal activating the fusion protein gB that can be blocked by neutralizing antibodies.

Unlabelled: Herpesviruses require membrane fusion for entry and spread, a process facilitated by the fusion glycoprotein B (gB) and the regulatory factor gH/gL. The human cytomegalovirus (HCMV) gH/gL can be modified by the accessory protein gO, or the set of proteins UL128, UL130 and UL131. While the binding of the gH/gL/gO and gH/gL/UL128-131 complexes to cellular receptors including PDFGRα and NRP2 has been well-characterized structurally, the specific role of receptor engagements by the gH/gL/gO and gH/gL/UL128-131 in regulation of fusion has remained unclear.

BCAA interactions: how do they influence broiler performance, intestinal morphometry, lipid profile, and liver health?

An experiment was conducted to assess the effects of the BCAA and their interactions on performance, carcass composition, lipid metabolism, liver health, and intestinal morphometry in broiler chickens. Male chickens ( = 1080) were randomly assigned into floor pens in a 3 × 3 factorial design with 3 dietary ratios of SID Leu:Lys (110, 150, and 190%), and 3 dietary ratios of SID Ile-Val:Lys (68-77, 78-87, and 88-97%). Performance parameters were assessed from 1 to 35 days of age.

Elevated CO in dynamic controlled atmosphere storage: Impact on anaerobic metabolism and overall quality of 'Maxi Gala' apples.

Background: The present study investigated the effects of high CO partial pressures (pCO) in dynamic controlled atmosphere monitored by respiratory quotient (DCA-RQ 1.3) on the anaerobic metabolism compounds, physiological disorders and overall quality of 'Maxi Gala' apples after 9 months of storage (2.0 °C), plus 7 days of shelf life (20 °C).

Improved survival of advanced melanoma patients receiving immunotherapy with concomitant antithrombotic therapy - A multicenter study on 2419 patients from the prospective skin cancer registry ADOReg.

Background: Cancer immunotherapy has revolutionized melanoma treatment, but the high number of non-responders still emphasizes the need for improvement of therapy. One potential avenue for enhancing anti-tumor treatment is through the modulation of coagulation and platelet activity. Both have been found to play an important role in the tumor microenvironment, tumor growth and metastasis.

MRI for Scaphoid Nonunion: Utilization Rates, Factors Associated with Utilization, and Subsequent Vascularized Bone Graft Use.

Purpose: The use of magnetic resonance imaging (MRI) for evaluation of scaphoid nonunion may be an example of low-value imaging for the treatment of scaphoid nonunion. The purpose of this study was to investigate variation in MRI use for scaphoid nonunion, the association of MRI with a vascularized bone graft (VBG) and to develop consensus on MRI use for scaphoid nonunion.

Methods: We identified patients >18 years of age who underwent scaphoid nonunion surgery between 2010 and 2019 using a claims database.
