A novel molecular structure that bridges the fields of molecular optical cycling and molecular photoswitching is presented. It is based on a photoswitching molecule azobenzene functionalized with one and two CaO- groups, which can act as optical cycling centers (OCCs). This paper characterizes the electronic structure of the resulting model systems, focusing on three questions: (1) how the electronic states of the photoswitch are impacted by a functionalization with an OCC; (2) how the states of the OCC are impacted by the scaffold of the photoswitch; and (3) whether the OCC can serve as a spectroscopic probe of isomerization.

Nuclear clocks based on this transition are expected to be more robust than and may outperform current optical atomic clocks. These clocks also promise sensitive tests for new physics beyond the standard model.

She was committed to Saint-Jean-de-Dieu, separated from her newborn and husband, who would send dozens of letters inquiring about her health and longing for the day she could return home. Sadly, that return never happened.

AH is a complex disease encompassing the dysregulation of many cells and cell subpopulations. This study used a hepatic spatial transcriptomic and proteomic approach (10X Genomics Visium) to identify hepatic cell populations and their associated transcriptomic and proteomic alterations in human AH.

However, whether AMPK activity is spatially regulated, and the implications for cell function, have been unclear. We now report that AMPK associates with the Golgi, and that its activation by two specific pharmacological activators leads to Golgi fragmentation similar to that caused by the antibiotic Golgicide A, an inhibitor of Golgi-specific Brefeldin A resistance factor-1 (GBF1), a guanine nucleotide exchange factor that targets ADP-ribosylation factor 1 (ARF1).

However, training initiatives are not sufficient to move effective treatments into routine practice. Patient and clinic factors can impact evidence-based psychotherapies use.

Clinicians accessed symptom reports within electronic patient records.

Background: The purpose of this qualitative study was to identify emergent rehabilitation innovations and clinician perceptions influencing their implementation and outcomes related to hospital discharge decision-making during the Coronavirus 2019 pandemic.
Methods: Rehabilitation clinicians were recruited from the Veterans Affairs Health Care System and participated in individual semi-structured interviews guided by the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework. Data were analyzed using a rapid qualitative, deductive team-based approach informed by directed content analysis.
Background: Locally advanced cervical cancer is treated with chemoradiotherapy (standard of care), but many patients still relapse and die from metastatic disease. We investigated chemoradiotherapy with or without induction chemotherapy to determine whether induction chemotherapy improves both progression-free survival and overall survival.
Methods: The INTERLACE trial was a multicentre, randomised phase 3 trial done at 32 medical centres in Brazil, India, Italy, Mexico, and the UK.
Police officers are increasingly tasked with responding to people in crisis (PIC), often resulting in transfers to emergency departments (EDs) where they can encounter challenges like long wait times, safety concerns, and conflicting perspectives between the medical and legal systems. This qualitative study explores the experiences of police officers during the transfer of PIC to ED nurses and staff. Eleven police officers were recruited and interviewed, providing contextual information about ED transfers in the greater Montreal area.

Background: Whether or not to progress from a pilot study to a definitive trial is often guided by pre-specified quantitative progression criteria with three possible outcomes. Although the choice of these progression criteria will help to determine the statistical properties of the pilot trial, there is a lack of research examining how they, or the pilot sample size, should be determined.
Methods: We review three-outcome trial designs originally proposed in the phase II oncology setting and extend these to the case of external pilots, proposing a unified framework based on univariate hypothesis tests and the control of frequentist error rates.
The "knallgas" bacterium is attracting interest due to its extremely versatile metabolism. can use hydrogen or formic acid as an energy source, fixes CO the Calvin-Benson-Bassham (CBB) cycle, and grows on organic acids and sugars. Its tripartite genome is notable for its size and duplications of key genes (CBB cycle, hydrogenases, and nitrate reductases).

Within these contexts, the term is frequently either left undefined or defined rather narrowly, confined to clinical observations or guidelines targeted at healthcare providers and negating the multifaceted nature of crisis as described by those with lived experience. Therefore, the aim of this paper is to explore the characteristics of and provide a conceptual definition for the concept of 'mental health crisis'.

The results of that efficacy study indicated more clients attended the initial session when receiving the letter (77%) compared to receiving a reminder telephone call (51%). The present study examines the effectiveness of messages addressing prospective clients' motivation and expectations for outpatient gambling treatment across an entire treatment system.

However, to what extent and how Asc modulates metabolism is largely unknown. We investigated the consequences of chloroplastic and total cellular Asc deficiencies by studying chloroplastic Asc transporter mutant lines lacking PHOSPHATE TRANSPORTER 4; 4 and the Asc-deficient vtc2-4 mutant of Arabidopsis (Arabidopsis thaliana).

LiSrAlF_{6} crystals doped with ^{229}Th are used in a laser-based search for the nuclear isomeric transition. Two spectroscopic features near the nuclear transition energy are observed. The first is a broad excitation feature that produces redshifted fluorescence that decays with a timescale of a few seconds.
