Mitochondrial dysfunction in drug-induced hepatic steatosis: recent findings and current concept.

Mitochondrial activity is necessary for the maintenance of many liver functions. In particular, mitochondrial fatty acid oxidation (FAO) is required for energy production and lipid homeostasis. This key metabolic pathway is finely tuned by the mitochondrial respiratory chain (MRC) activity and different transcription factors such as peroxisome proliferator-activated receptor α (PPARα).

Double trouble? Quantifying the risk from co-exposure to multiple pathogens in Tenebrio molitor at different CO concentrations.

The insect mass-rearing industry to produce feed and food is expanding rapidly. Insects in production frequently encounter multiple pathogens and environmental stressors simultaneously, which can lead to significant economic losses. Our understanding of the interactions between different stressors remains limited, and existing methods primarily focus on determining overall patterns of additivity, synergism, or antagonism.

I-motif formation in the promoter region of the B-MYB proto-oncogene.

Understanding the mechanisms of carcinogenesis is essential to combat cancer. The search for alternative targets for anticancer therapy has gained interest, particularly when focused on upstream pathways. This strategy is particularly relevant when the encoded target proteins are known - or believed - to be "undruggable", as has been reported for the B-MYB oncogene.

Impact of comorbidities on the mortality benefits of lung cancer screening: a post-hoc analysis of PLCO and NLST trials.

Hypothesis: To evaluate how comorbidities affect mortality benefits of lung cancer screening (LCS) with low-dose computed-tomography (LDCT).

Methods: We developed a comorbidity index (PLCO-ci) using LCS-eligible participants' data from the Prostate Lung Colorectal and Ovarian (PLCO) trial (training set) and the National Lung Screening Trial (NLST) (validation set). PLCO-ci predicts 5-year non-lung cancer (LC) mortality using a regularized Cox model; with performance evaluated by the area under the ROC curve (ROC).

Effect of mass campaigns with full and fractional doses of pneumococcal conjugate vaccine (Pneumosil) on the reduction of nasopharyngeal pneumococcal carriage in Niger: a three-arm, open-label, cluster-randomised trial.

Background: In settings with low pneumococcal conjugate vaccine (PCV) coverage, multi-age cohort mass campaigns could increase population immunity, and fractional dosing could increase affordability. We aimed to evaluate the effect of mass campaigns on nasopharyngeal pneumococcal carriage of Pneumosil (PCV10) in children aged 1-9 years in Niger.

Methods: In this three-arm, open-label, cluster-randomised trial, 63 clusters of one to four villages in Niger were randomly assigned (3:3:1) using block randomisation to receive campaigns consisting of a single full dose of a 10-valent PCV (Pneumosil), a single one-fifth dose of Pneumosil, or no campaign.

The effectiveness of two doses of recombinant hepatitis E vaccine in response to an outbreak in Bentiu, South Sudan: a case-control and bias indicator study.

Background: Hepatitis E virus (HEV) is a leading cause of acute viral hepatitis, particularly in Asia and Africa, where HEV genotypes 1 and 2 are prevalent. Although a recombinant vaccine, Hecolin, is available, it has not been used to control outbreaks. The licensed three-dose regimen might pose challenges for it to be an impactful outbreak control tool.

Durvalumab with or without bevacizumab with transarterial chemoembolisation in hepatocellular carcinoma (EMERALD-1): a multiregional, randomised, double-blind, placebo-controlled, phase 3 study.

Background: Transarterial chemoembolisation (TACE) is standard of care for patients with unresectable hepatocellular carcinoma that is amenable to embolisation; however, median progression-free survival is still approximately 7 months. We aimed to assess whether adding durvalumab, with or without bevacizumab, might improve progression-free survival.

Methods: In this multiregional, randomised, double-blind, placebo-controlled, phase 3 study (EMERALD-1), adults aged 18 years or older with unresectable hepatocellular carcinoma amenable to embolisation, an Eastern Cooperative Oncology Group performance status of 0 or 1 at enrolment, and at least one measurable intrahepatic lesion per modified Response Evaluation Criteria in Solid Tumours (RECIST) were enrolled at 157 medical sites including research centres and general and specialist hospitals in 18 countries.

DNA-binding affinity and specificity determine the phenotypic diversity in BCL11B-related disorders.

BCL11B is a Cys2-His2 zinc-finger (C2H2-ZnF) domain-containing, DNA-binding, transcription factor with established roles in the development of various organs and tissues, primarily the immune and nervous systems. BCL11B germline variants have been associated with a variety of developmental syndromes. However, genotype-phenotype correlations along with pathophysiologic mechanisms of selected variants mostly remain elusive.

Tertiary lymphoid structures and cancer immunotherapy: From bench to bedside.

Tertiary lymphoid structures (TLSs) are organized ectopic lymphoid aggregates within the tumor microenvironment that serve as crucial sites for the development of adaptive antitumor cellular and humoral immunity. TLSs have been consistently documented in numerous cancer types, correlating with improved prognosis and enhanced responses to immunotherapy, especially immune-checkpoint blockade (ICB). Given the potential role of TLSs as predictive biomarkers for the efficacy of ICB in cancer patients, the therapeutic manipulation of TLSs is gaining significant attention as a promising avenue for cancer treatment.

Species-specific mercury speciation in billfishes and its implications for food safety monitoring and dietary advice.

Humans are exposed to toxic methylmercury mainly by consuming marine fish, in particular top predator species like billfishes or tunas. In seafood risk assessments, mercury is assumed to be mostly present as organic methylmercury in predatory fishes; yet high percentages of inorganic mercury were recently reported in marlins, suggesting markedly different methylmercury metabolism across species. We quantified total mercury and methylmercury concentrations in muscle of four billfish species from the Indian and the Pacific oceans to address this knowledge gap.

Objective: To compare the corneal topographic parameters and ocular surface parameters of ocular rosacea (OR) patients across skin subtypes of the disease and healthy controls.

Methods: This prospective study included 180 eyes of 90 OR patients and 60 eyes of 30 healthy controls. Among the OR patients, 30 had phymatous (60 eyes), 30 had erythematotelangiectatic (60 eyes) and 30 had papulopustular skin types (60 eyes).

Intermodulation frequencies reveal common neural assemblies integrating facial and vocal fearful expressions.

Effective social communication depends on the integration of emotional expressions coming from the face and the voice. Although there are consistent reports on how seeing and hearing emotion expressions can be automatically integrated, direct signatures of multisensory integration in the human brain remain elusive. Here we implemented a multi-input electroencephalographic (EEG) frequency tagging paradigm to investigate neural populations integrating facial and vocal fearful expressions.

Machine learning and statistical shape modelling for real-time prediction of stent deployment in realistic anatomies.

The rise in minimally invasive procedures has created a demand for efficient and reliable planning software to predict intra- and post-operative outcomes. Surrogate modelling has shown promise, but challenges remain, particularly in cardiovascular applications, due to the complexity of parametrising anatomical structures and the need for large training datasets. This study aims to apply statistical shape modelling and machine learning for predicting stent deployment in real time using patient-specific models.

Influence of meteorological changes on the occurrence of cerebral aneurysm rupture in the Montpellier region: A retrospective study.

Background/context: Aneurysmal subarachnoid hemorrhage (aSAH) is a sudden and potentially serious event. Recognized risk factors of aSAH include smoking, high blood pressure, and alcohol consumption. Some studies have reported associations between risk of aSAH and climatic conditions, but no consensus exists.

Quality-adjusted time without symptoms or toxicity analysis of trastuzumab deruxtecan versus trastuzumab emtansine in HER2- positive metastatic breast cancer patients based on secondary use of the DESTINY-Breast03 trial.

Objective: DESTINY-Breast03, a randomised, phase 3 trial, evaluated trastuzumab deruxtecan (T-DXd) versus trastuzumab emtansine (T-DM1) in patients with human epidermal growth factor receptor (HER2)-positive unresectable and/or metastatic breast cancer who progressed on or after treatment with trastuzumab and a taxane. At the current data cut off overall survival analysis, T-DXd demonstrated a substantial improvement in overall survival over T-DM1. This secondary analysis use of DESTINY-Breast03 aimed to further evaluate the treatment differences using quality-adjusted survival time without symptoms or toxicity (Q-TWiST) methods.

Assessment of a 6-arylaminobenzamide lead derivative as a potential core scaffold for S1P positron emission tomography radiotracer development.

Sphingosine-1-phosphate-5 receptors (S1P) are predominantly expressed in oligodendrocytes and as a result have been proposed as an important target in Multiple Sclerosis (MS). Selective S1P radiotracers could enable in vivo positron emission tomography (PET) imaging of oligodendrocytes activity. Here we report the synthesis, radiolabelling and first preclinical evaluation of the pharmacokinetics and binding properties of a lead 6-arylaminobenzamide derivative, 6-(mesitylamino)-2-methoxy-3-methylbenzamide (also named as TEFM180), as a potential core scaffold for development of novel S1P PET radiotracers.

CAR-T cell therapy for breast cancer: Current status and future perspective.

Within the expanding therapeutic landscape for breast cancer (BC), metastatic breast cancer (MBC) remains virtually incurable and tend to develop resistance to conventional treatments ultimately leading to metastatic progression and death. Cellular immunotherapy (CI), particularly chimeric antigen receptor-engineered T (CAR-T) cells, has emerged as a promising approach for addressing this challenge. In the wake of their striking efficacy against hematological cancers, CAR-T cells have also been used where the clinical need is greatest - in patients with aggressive BCs.
