Solvent-Dependent Reactivity of Fe(CO) under Superacidic and Oxidative Conditions.

Herein, we report the solvent-dependent reactivity of Fe(CO) toward AsF in either anhydrous HF or liquid SO. The reaction of Fe(CO) with the superacid HF/AsF leads to the protonation of the iron center and allows for the first-time structural characterization of [FeH(CO)] in the solid state, representing one of the most acidic transition metal hydride complexes to ever be isolated and structurally characterized. In the aprotic but oxidation-stable solvent SO, Fe(CO) is oxidized and dimerized to [Fe(CO)], which is isoelectronic with well-known Mn(CO).

Gastric remnant volvulus following gastric sleeve conversion to Roux-en-Y gastric bypass: a case report.

Gastric remnant volvulus following Roux-en-Y gastric bypass (RYGB) surgery is rare, with only two previously reported cases. Herein, we present the first case of gastric remnant volvulus following gastric sleeve conversion to RYGB in a 32-year-old female. Management for gastric remnant volvulus has not been clearly described in the literature due to the rarity of cases; however, previously documented cases of gastric remnant volvulus following RYGB were managed with gastropexy or resection of the gastric remnant.

One organ to infect them all: the Cuscuta haustorium.

Background: Research on the parasitic plant genus Cuscuta has flourished since the genomes of several of its species were published. Most of the research revolves around the iconic infection organ that secures the parasite's sustenance: the haustorium. The interest in understanding the structure-function-regulation relationship of the haustorium is based as much on the wish to find ways to keep the parasite under control as on the opportunities it offers to shed light on various open questions in plant biology.

Using large language models to detect outcomes in qualitative studies of adolescent depression.

Objective: We aim to use large language models (LLMs) to detect mentions of nuanced psychotherapeutic outcomes and impacts than previously considered in transcripts of interviews with adolescent depression. Our clinical authors previously created a novel coding framework containing fine-grained therapy outcomes beyond the binary classification (eg, depression vs control) based on qualitative analysis embedded within a clinical study of depression. Moreover, we seek to demonstrate that embeddings from LLMs are informative enough to accurately label these experiences.
