Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) continues to persist, demonstrating the risks posed by emerging infectious diseases to national security, public health, and the economy. Development of new vaccines and antibodies for emerging viral threats requires substantial resources and time, and traditional development platforms for vaccines and antibodies are often too slow to combat continuously evolving immunological escape variants, reducing their efficacy over time. Previously, we designed a next-generation synthetic humanized nanobody (Nb) phage display library and demonstrated that this library could be used to rapidly identify highly specific and potent neutralizing heavy chain-only antibodies (HCAbs) with prophylactic and therapeutic efficacy in vivo against the original SARS-CoV-2.

This integrated computational and experimental study comprehensively examines the viability of competing inner-sphere electron transfer (ISET) and outer-sphere electron transfer (OSET) processes in [Cu(dap)]-mediated atom-transfer radical additions (ATRA) of olefins and CFSOCl that can deliver both R-SOCl and R-Cl products. Five sterically- and electronically-varied representative alkenes were selected from which to explore and reconcile a range of experimentally observed outcomes. Findings are consistent with photoexcited [Cu(dap)] initiating photoelectron transfer via ISET and the subsequent regeneration of the oxidized catalyst via ISET in the ground state to close the catalytic cycle and liberate products.

Photoredox catalysis is a powerful tool to access challenging and diverse syntheses. Absorption of visible light forms the excited state catalyst (*PC) but photons may be wasted if one of several unproductive pathways occur. Facile dissociation of the charge-separated encounter complex [PC:D], also known as (solvent) cage escape, is required for productive chemistry and directly governs availability of the critical PC intermediate.

Cameron lesions are rare causes of upper gastrointestinal bleeding (UGIB). The lesions are linear erosions or ulcers that develop in the sac of a hiatal hernia, which often go unnoticed in the upper gastrointestinal system, and are a prevalent cause of anemia resulting from iron deficiency. Postponed treatment can result in severe consequences such as potentially fatal hemorrhaging.

Article Synopsis
  • - Hypernatremia is a condition where sodium levels in the blood exceed 145 mmol/L, commonly seen in critically ill patients and psychiatric patients, especially those with major depressive disorder, due to factors like dehydration and medication effects.
  • - Treatment for chronic hypernatremia involves administering isotonic saline and D5W to restore sodium levels safely, aiming for a decrease of 8-10 mmol/day, while acute cases require a more gradual correction of 1 mmol/L/hour in the initial hours.
  • - A case study of a 51-year-old woman with severe depression showed successful management of her severe hypernatremia (191 mmol/L) with careful fluid administration, highlighting the importance of early intervention to prevent complications.

Aortoesophageal fistula (AEF) is an uncommon complication of esophageal cancer and can be extremely fatal if left untreated. Compared to open repair, thoracic endovascular aortic repair (TEVAR), a less invasive technique, is the initial recommended treatment in cases of hemorrhagic shock secondary to AEF, as this procedure showed a favorable outcome in controlling the overt bleeding. Here, we present a case of a patient with a history of stage IV esophageal cancer being treated with chemotherapy and an esophageal stent due to a previous tracheoesophageal fistula who presented to the emergency room due to severe gastroesophageal bleeding and hemorrhagic shock.

Article Synopsis
  • - Two-dimensional MoS nanosheets were created using an exfoliation technique with the help of peptides and sonication in water, achieving better results with uncapped peptides compared to capped ones.
  • - Nanosheets produced with uncapped MoSBP1 are thinner and mostly single-layered, while capped versions tend to form multilayered structures of up to four layers.
  • - Molecular dynamics simulations show that uncapped peptides are more effective at keeping gaps between nanosheets open longer, preventing them from re-stacking and aggregating, which explains the improved exfoliation efficiency observed in experiments.

Here, we report a practical route to medicinally interesting lycorine congeners alongside formal syntheses of various lycorine-type natural products, including lycorine itself. The efficiency of our strategy derives from a back-to-back 5/6 radical cyclization sequence, which we systematically studied both experimentally and computationally. The results of our work will facilitate future development of urgently needed antiviral therapeutics based on lycorine.

Laccases from white-rot fungi catalyze lignin depolymerization, a critical first step to upgrading lignin to valuable biodiesel fuels and chemicals. In this study, a wildtype laccase from the basidiomycete (Fom_lac) and a variant engineered to have a carbohydrate-binding module (Fom_CBM) were studied for their ability to catalyze cleavage of β-O-4' ether and C-C bonds in phenolic and non-phenolic lignin dimers using a nanostructure-initiator mass spectrometry-based assay. Fom_lac and Fom_CBM catalyze β-O-4' ether and C-C bond breaking, with higher activity under acidic conditions (pH < 6).

The optoelectronic properties of colloidal quantum dots (cQDs) depend critically on the absolute energy of the conduction and valence band edges. It is well known these band-edge energies are sensitive to the ligands on the cQD surface, but it is much less clear how they depend on other experimental conditions, like solvation. Here, we experimentally determine the band-edge positions of thin films of PbS and ZnO cQDs via spectroelectrochemical measurements.

Reaction of the dinucleating ligand 2,7-bis(6-methyl-2-pyridyl)-1,8-naphthyridine (L) with the Mn and Mn precursors MnBr(CO) and MnCl resulted in the formation of the monometallic complexes [MnBr(CO)(L)] (1) and [MnCl(L)] (3). In both cases, formation of bimetallic manganese complexes could be achieved by reduction with KC, yielding the carbonyl-bridged complex [Mn(CO)(L)] (2) and the helicate complex [Mn(L)] (4), respectively. EPR results demonstrate that 4 represents a novel, weakly antiferromagnetically coupled homovalent dimer ( = -0.
