Natural Densitals.

The concept of natural densitals (NDs) and their amplitudes is introduced. These quantities provide the spectral decomposition of the cumulant of the two-electron density that, by definition, quantifies the extent of electron correlation. Consequently, they are ideally suited for a rigorous description of electron correlation effects in Coulombic systems.

Oligogenic risk score for Gilles de la Tourette syndrome reveals a genetic continuum of tic disorders.

Gilles de la Tourette syndrome (GTS) and other tic disorders (TDs) have a substantial genetic component with their heritability estimated at between 60 and 80%. Here we propose an oligogenic risk score of TDs using whole-genome sequencing (WGS) data from a group of Polish GTS patients, their families, and control samples (n = 278). In this study, we first reviewed the literature to obtain a preliminary list of 84 GTS/TD candidate genes.

Anticancer properties of histone deacetylase inhibitors - what is their potential?

Introduction: Histone modifications are crucial epigenetic mechanisms for regulating gene expression. Histone acetyltransferases and deacetylases (HDACs) catalyze histone acetylation, a process that mediates transcription. Over recent decades, studies have demonstrated that targeting histone acetylation can be effective in cancer treatment, leading to the development and approval of several HDAC inhibitors.

Detection of Human Bladder Epithelial Cancerous Cells with Atomic Force Microscopy and Machine Learning.

The development of noninvasive methods for bladder cancer identification remains a critical clinical need. Recent studies have shown that atomic force microscopy (AFM), combined with pattern recognition machine learning, can detect bladder cancer by analyzing cells extracted from urine. However, these promising findings were limited by a relatively small patient cohort, resulting in modest statistical significance.

Case Studies on Dissocial Personality-Bad or Ill?

Dissocial personality is understood as a personality that does not ideologize most social norms and is characterized by a lack of empathy. Precise criteria for diagnosing dissocial personality are included in the ICD-10 classification, which is still in force in Poland. This classification is widely available in both Polish and English.

From Pseudocyclic to Macrocyclic Ionophores: Strategies toward the Synthesis of Cyclic Monensin Derivatives.

There has been a long search for a simple preparation of new cyclic analogues of ionophore antibiotics. We report a simple and general synthesis of three new cyclic derivatives of polyether ionophore, monensin A (MON). The application of the Huisgen 1,3-dipolar cycloaddition of azides and terminal alkynes to macrocyclization results in a concise, synthetic route to monensin lacton or lactam in only 4 steps.

Use of psychedelic treatments in psychiatric clinical practice: an EPA policy paper.

Background: Recent years show an exponential increased interest ("renaissance") in the use of psychedelics for the treatment of mental disorders and broader. Some of these treatments, such as psilocybin for depression, are in the process of formal regulation by regulatory bodies in the US (FDA) and Europe (EMA), and as such on the brink of real-world implementation. In the slipstream of these developments increasing commercial initiatives are taking shape.

Impact of a very low-calorie ketogenic diet on metabolic and microbiota outcomes in post-bariatric patients and bariatric-Naïve individuals: A comparative pilot study.

Aims: To date, bariatric surgery (BS) is the most effective long-term treatment for obesity, but weight regain (WR) is common. The very low-calorie ketogenic diet (VLCKD) is effective for weight loss and may influence gut microbiota (GM) composition, but it has been scarcely evaluated in post-bariatric patients. This study compared the efficacy and safety of a VLCKD in patients with WR post-bariatric surgery (BS+) and in bariatric surgery-naïve patients (BS-).

Detection of vaccine-derived poliovirus type 2 from sewage samples and public health response, Poland, November to December 2024.

In October and December 2024, circulating vaccine-derived poliovirus type 2 (cVDPV2) was detected from two wastewater samples in Poland during routine environmental surveillance. The first isolate was characterised and matched previous cVDPV2 isolates detected in Spain in September, as well as in Germany, Finland, and the United Kingdom in November and December 2024. In response to the event, active surveillance for acute flaccid paralysis (AFP) has been strengthened, and the frequency of environmental sample collection has been increased.

Towards a long-term stable MAPbBr single crystal-based photoconductor with a high on/off ratio and detectivity.

Photodetectors based on lead halide perovskites often show excellent performance but poor stability. Herein, we demonstrate a photodetector based on MAPbBr single crystals passivated with an ultrathin layer of PbSO, which shows superior detectivity and on/off ratios compared to the control device due to the combined effect of lower surface traps, reduced recombination and low dark current. In addition, the device retained ∼56% of its initial * with an impressive on/off ratio of ∼801 after one year compared to ∼22% of * and an on/off ratio of ∼6 of the control device.

Advances in cryo-electron microscopy (cryoEM) for structure-based drug discovery.

Introduction: Macromolecular X-ray crystallography (XRC), nuclear magnetic resonance (NMR), and cryo-electron microscopy (cryoEM) are the primary techniques for determining atomic-level, three-dimensional structures of macromolecules essential for drug discovery. With advancements in artificial intelligence (AI) and cryoEM, the Protein Data Bank (PDB) is solidifying its role as a key resource for 3D macromolecular structures. These developments underscore the growing need for enhanced quality metrics and robust validation standards for experimental structures.

Provided and received positive and negative social control, relationship satisfaction, and sedentary behavior in parent-child dyads.

Background: The close relationship processes and health model and the dyadic health influence model posit that relationship beliefs (eg, relationship satisfaction) and influence strategies (eg, provision and receipt of positive and negative social control) mediate health behavior change. However, evidence for such mediation in parent-child dyads is limited.

Purpose: Two complementary mediation hypotheses were tested: (1) social control forms indirect relationships with sedentary behavior (SB), via relationship satisfaction acting as a mediator; and (2) relationship satisfaction forms indirect relationships with SB, with social control operating as a mediator.

Population Pharmacokinetic Modeling of Certepetide in Human Subjects With Metastatic Pancreatic Ductal Adenocarcinoma.

Certepetide (aka LSTA1 and CEND-1) is a novel cyclic tumor-targeting internalizing arginyl glycylaspartic acid peptide being developed to treat solid tumors. Certepetide is designed to overcome existing challenges in treating solid tumors by delivering co-administered anticancer drugs into the tumor while selectively depleting immunosuppressive T cells, enhancing cytotoxic T cells in the tumor microenvironment, and inhibiting the metastatic cascade. A population pharmacokinetic (PK) analysis was conducted to characterize the concentration-time profile of patients with metastatic exocrine pancreatic cancer receiving certepetide in combination with nab-paclitaxel and gemcitabine, and to investigate the effects of clinically relevant covariates on PK parameters.
