Zinc and RNA Binding Is Linked to the Conformational Flexibility of ZRANB2: A CCCC-Type Zinc Finger Protein.

Ran-binding domain-containing protein 2 (ZRANB2) is a zinc finger (ZF) protein that plays a key role in alternative splicing. ZRANB2 is composed of two ZF domains that contain four invariant cysteine residues per domain. ZRANB2 binds RNA targets that contain AGGUAA sequence motifs.

DART.2: bidirectional synaptic pharmacology with thousandfold cellular specificity.

Precision pharmacology aims to manipulate specific cellular interactions within complex tissues. In this pursuit, we introduce DART.2 (drug acutely restricted by tethering), a second-generation cell-specific pharmacology technology.

[Intravesical oxybutynin treatment for neurogenic detrusor overactivity : Efficacy and safety data from clinical practice with the first intravesical oxybutynin treatment authorized in Germany].

Existing therapies for neurogenic detrusor overactivity (NDO), i.e. oral anticholinergics and botulinum toxin injections, can be associated with serious adverse effects or are not always sufficiently effective.

From rare events to systematic data collection: the RESCUED registry for sudden cardiac death in the young in Germany.

Background: Approximately one-third of sudden cardiac deaths in the young (SCDY) occur due to a structural cardiac disease. Forty to fifty percent of SCDY cases remain unexplained after autopsy (including microscopic and forensic-toxicological analyses), suggesting arrhythmia syndromes as a possible cause of death. Due to the possible inheritability of these diseases, blood relatives of the deceased may equally be carriers of the causative genetic variations and therefore may have an increased cardiac risk profile.

Potency of a small molecule that targets the molluscum contagiosum virus processivity factor increases when conjugated to a tripeptide.

We recently developed compound FC-7269 for targeting the Molluscum contagiosum virus processivity factor (mD4) and demonstrated its ability to inhibit viral processive DNA synthesis in vitro and cellular infection of an mD4-dependent virus (Antiviral Res 211, 2023,105520). However, despite a thorough medicinal chemistry campaign we were unable to generate a potent second analog as a requisite for drug development. We overcame this impasse, by conjugating a short hydrophobic trivaline peptide to FC-7269 to produce FC-TriVal-7269 which significantly increased antiviral potency and reduced cellular toxicity.

PROTAC-mediated degradation of HIV-1 Nef efficiently restores cell-surface CD4 and MHC-I expression and blocks HIV-1 replication.

The HIV-1 Nef accessory factor enhances the viral life cycle in vivo, promotes immune escape of HIV-infected cells, and represents an attractive antiretroviral drug target. However, Nef lacks enzymatic activity and an active site, complicating traditional occupancy-based drug development. Here we describe the development of proteolysis targeting chimeras (PROTACs) for the targeted degradation of Nef.

Assessing Longitudinal Treatment Efficacies and Alterations in Molecular Markers Associated with Glutamatergic Signaling and Immune Checkpoint Inhibitors in a Spontaneous Melanoma Mouse Model.

Previous work done by our laboratory described the use of an immunocompetent spontaneous melanoma-prone mouse model, TGS (TG-3/SKH-1), to evaluate treatment outcomes using inhibitors of glutamatergic signaling and immune checkpoint for 18 weeks. We showed a significant therapeutic efficacy with a notable sex-biased response in male mice. In this follow-up 18-week study, the dose of the glutamatergic signaling inhibitor was increased (from 1.

[Obstetrical outcome of renal transplant patients followed in a type III maternity hospital. Retrospective study from 2000 to 2020].

Aim: To describe pregnancy outcome of kidney transplant patients till 1 year postpartum.

Methods: This retrospective, monocentric study included 15 kidney transplant patients who presented 18 pregnancies, between January 2000 and January 2020. For each of them, we searched for possible obstetrical, fetal and renal complications and we evaluated renal function before, during and after pregnancy.

Standardized Comparison of Voice-Based Information and Documentation Systems to Established Systems in Intensive Care: Crossover Study.

Background: The medical teams in intensive care units (ICUs) spend increasing amounts of time at computer systems for data processing, input, and interpretation purposes. As each patient creates about 1000 data points per hour, the available information is abundant, making the interpretation difficult and time-consuming. This data flood leads to a decrease in time for evidence-based, patient-centered care.

PROTAC-mediated Degradation of HIV-1 Nef Efficiently Restores Cell-surface CD4 and MHC-I Expression and Blocks HIV-1 Replication.

The HIV-1 Nef accessory factor is critical to the viral life cycle where it promotes immune escape of HIV-infected cells and viral persistence. While these features identify Nef as an attractive antiretroviral drug target, Nef lacks enzymatic activity and an active site, complicating development of occupancy-based drugs. Here we describe the development of proteolysis targeting chimeras (PROTACs) for the targeted degradation of Nef.

Amide- and bis-amide-linked highly potent and broadly active antifungal agents for the treatment of invasive fungal infections- towards the discovery of pre-clinical development candidate FC12406.

Most fungal infections are common, localized to skin or mucosal surfaces and can be treated effectively with topical antifungal agents. However, while invasive fungal infections (IFIs) are uncommon, they are very difficult to control medically, and are associated with high mortality rates. We have previously described highly potent bis-guanidine-containing heteroaryl-linked antifungal agents, and were interested in expanding the range of agents to novel series so as to reduce the degree of aromaticity (with a view to making the compounds more drug-like), and provide broadly active high potency derivatives.

Levamisole derivatives as immune modulators for the treatment of amyotrophic lateral sclerosis (ALS).

To discover derivatives of the anthelmintic drug levamisole, which has been reported to possess immune-modulatory properties, as treatments for amyotrophic lateral sclerosis (ALS), which has been suggested to be in part an autoimmune disease. We have synthesized ten analogs of the racemic version of levamisole, tetramisole, as well as eleven analogs on a related system. All of the analogs have been tested for their ability to affect the response of five ALS-relevant cytokines.

Fluorescence confocal microscopy on liver specimens for full digitization of transplant pathology.

Fluorescence confocal microscopy (FCM) is a rapidly evolving tool that provides real-time virtual HE images of native tissue. Data about the potential of FCM as an alternative to frozen sections for the evaluation of donor liver specimens are lacking so far. The aim of the current study was to determine the value of FCM in liver specimens according to the criteria of the German Society for Organ Procurement.

A Spontaneous Melanoma Mouse Model Applicable for a Longitudinal Chemotherapy and Immunotherapy Study.

Mouse models that reflect human disorders provide invaluable tools for the translation of basic science discoveries to clinical therapies. However, many of these in vivo therapeutic studies are short term and do not accurately mimic patient conditions. In this study, we used a fully immunocompetent, transgenic mouse model, TGS, in which the spontaneous development of metastatic melanoma is driven by the ectopic expression of a normal neuronal receptor, mGluR1, as a model to assess longitudinal treatment response (up to 8 months) with an inhibitor of glutamatergic signaling, troriluzole, which is a prodrug of riluzole, plus an antibody against PD-1, an immune checkpoint inhibitor.

The NeuroSAFE frozen section technique during radical prostatectomy - Implementation and optimization of technical aspects in a routine pathology workflow.

Background And Aims: In prostate cancer patients, application of the NeuroSAFE frozen section technique during radical prostatectomy has been shown to increase the rate of nerve sparing surgery and to improve functional outcome for the patients. The aim of this study is to report on technical and organizational optimization opportunities of the procedure.

Material And Methods: All patients submitted to bilateral intraoperative frozen section from January 2018 until December 2020 (n = 452) were retrospectively analyzed and parameters such as turnaround time, staff situation in the laboratory and histologic properties of the tumors were assessed.

A small molecule that targets the processivity factor of molluscum contagiosum virus has therapeutic potential.

Molluscum contagiosum (MC) is an infectious disease that occurs only in humans with a tropism that is narrowly restricted to the outermost epidermal layer of the skin. Molluscum contagiosum virus (MCV) is the causative agent of MC which produces skin lesions that can persist for months to several years. MCV is efficiently transmitted by direct physical contact or by indirect contact with fomites.

Troriluzole inhibits methamphetamine place preference in rats and normalizes methamphetamine-evoked glutamate carboxypeptidase II (GCPII) protein levels in the mesolimbic pathway.

Riluzole, approved to manage amyotrophic lateral sclerosis, is mechanistically unique among glutamate-based therapeutics because it reduces glutamate transmission through a dual mechanism (i.e., reduces glutamate release and enhances glutamate reuptake).

Outcomes of Early Versus Late Tracheostomy in Patients With COVID-19: A Multinational Cohort Study.

Unlabelled: Timing of tracheostomy in patients with COVID-19 has attracted substantial attention. Initial guidelines recommended delaying or avoiding tracheostomy due to the potential for particle aerosolization and theoretical risk to providers. However, early tracheostomy could improve patient outcomes and alleviate resource shortages.

Personality maturation through sense of mastery? Longitudinal evidence from two education-to-work transition studies.

Objective: Why personality changes in young adulthood remains a critical theoretical and empirical question. We studied personality change during the education-to-work transition, including mean-level personality change and its specific timing, the degree of individual variability in change, and the link between sense of mastery and personality change.

Methods: We used two intensive longitudinal studies.

Antiretroviral Drug Discovery Targeting the HIV-1 Nef Virulence Factor.

While antiretroviral drugs have transformed the lives of HIV-infected individuals, chronic treatment is required to prevent rebound from viral reservoir cells. People living with HIV also are at higher risk for cardiovascular and neurocognitive complications, as well as cancer. Finding a cure for HIV-1 infection is therefore an essential goal of current AIDS research.

Tracheostomies of Patients With COVID-19: A Survey of Infection Reported by Health Care Professionals.

Background: Health care professionals (HCPs) performing tracheostomies in patients with COVID-19 may be at increased risk of infection.

Objective: To evaluate factors underlying HCPs' COVID-19 infection and determine whether tracheostomy providers report increased rates of infection.

Methods: An anonymous international survey examining factors associated with COVID-19 infection was made available November 2020 through July 2021 to HCPs at a convenience sample of hospitals, universities, and professional organizations.

From MAX Phase Carbides to Nitrides: Synthesis of VGaC, VGaN, and the Carbonitride VGaCN.

The research in MAX phases is mainly concentrated on the investigation of carbides rather than nitrides (currently >150 carbides and only <15 nitrides) that are predominantly synthesized by conventional solid-state techniques. This is not surprising since the preparation of nitrides and carbonitrides is more demanding due to the high stability and low diffusion rate of nitrogen-containing compounds. This leads to several drawbacks concerning potential variations in the chemical composition of the MAX phases as well as control of morphology, the two aspects that directly affect the resulting materials properties.

Surgery in combination with systemic chemotherapy is associated with improved survival in stage IV gallbladder cancer.

Background: Gallbladder cancer (GBC) is the most common biliary malignancy frequently metastatic at diagnosis with poor prognosis. While surgery remains the standard for early-stage GBC, the role of surgery in patients with metastatic gastrointestinal cancers is expanding due to improvements in systemic therapies. We sought to evaluate the survival of patients with stage IV GBC undergoing surgery in an era of improved multi-agent systemic therapy.
