Exploring Chronic Pain in Hemodialysis Patients: An Observational Study Based on the New IASP Classification for ICD-11.

Introduction: Pain is one of the most frequently reported symptoms in hemodialyzed (HD) patients, with prevalence rates between 33% and 82%. Risk factors for chronic pain in HD patients are older age, long-lasting dialysis history, several concomitant diseases, malnutrition, and others. However, chronic pain assessment in HD patients is rarely performed by specialists in pain medicine, with relevant consequences in terms of diagnostic and treatment accuracy.

From infection to immortality: The role of HPV and telomerase in head and neck cancer.

Head and neck squamous cell carcinomas (HNSCCs) represent a heterogeneous group of malignancies with multifactorial aetiologies. High-risk human papillomavirus (hrHPV) infections, particularly HPV16, and the dysregulation of telomerase activity, specifically through its catalytic subunit, telomerase reverse transcriptase (TERT) are among the key contributors to HNSCC development and progression. HPV promotes oncogenesis via the E6 and E7 oncoproteins, which inactivate tumour suppressors TP53 and RB1, leading to unchecked cellular proliferation.

Survival analysis of the non-metastatic cohort of the Italian Association for Medical Oncology (AIOM) Guideline Application in Real world: multi-Institutional Based survey of Adjuvant and first-Line pancreatic Ductal adenocarcinoma treatment in Italy (GARIBALDI).

Background: Non-metastatic pancreatic ductal adenocarcinoma (PDAC) presents a challenging scenario: the rarity of the disease, the limited number of completed prospective trials, and the shortcomings of comparability across series produce several controversial topics and unanswered questions. Guideline recommendations usually include all the different therapeutic options, de facto transferring to the multidisciplinary team the responsibility on the final decision. This secondary analysis of the GARIBALDI study was aimed to explore the correlation of center type, self-declared volume, and commitment with the overall survival (OS) in patients with non-metastatic PDAC.

Preretinal abnormal tissue before and after pars plana vitrectomy in macula-on rhegmatogenous retinal detachment: a multimodal imaging study.

Purpose: To quantitatively explore preretinal abnormal tissue (PAT) in macula-on rhegmatogenous retinal detachment (RRD) before and after surgery.

Methods: In this case-series study, PAT was detected by en-face optical coherence tomography images with custom slabs in eyes that underwent pars plana vitrectomy and SF6 for macula-on RRD.Main outcome measures were PAT area at baseline, 3-month and 6-month follow-up, and its relative change.

Self-Interacting Dark Sectors in Supernovae Can Behave as a Relativistic Fluid.

We revisit supernova (SN) bounds on a hidden sector consisting of millicharged particles χ and a massless dark photon. Unless the self-coupling is fine-tuned to be small, rather than exiting the SN core as a gas, the particles form a relativistic fluid and subsequent dark QED fireball, streaming out against the drag due to the interaction with matter. Novel bounds due to excessive energy deposition in the mantle of low-energy supernovae can be obtained.

Basic Science and Pathogenesis.

Background: Research into human brain tissue is important for medical scientific advancement. Brain Banks worldwide allow the receipt of brains for such purposes through voluntary donation. Attitude towards organ donation can be influenced by cultural, ethical and social factors.

Omega 6 fatty acids: helpful, harmless or harmful?

Purpose Of Review: This paper reviews the most recent literature from January 2023 to August 2024 on the physiological effects of n-6 polyunsaturated fatty acids (PUFAs), with a focus on linoleic acid (LA).

Recent Findings: Contrary to previous concerns that high LA intake may increase inflammation, most recent evidence supports the benefits of LA for cardiometabolic health. Several large studies report that higher blood LA levels correlate with reduced risks of coronary heart disease, stroke, and type 2 diabetes.

Search for Fractionally Charged Particles with CUORE.

The Cryogenic Underground Observatory for Rare Events (CUORE) is a detector array comprised by 988 5  cm×5  cm×5  cm TeO_{2} crystals held below 20 mK, primarily searching for neutrinoless double-beta decay in ^{130}Te. Unprecedented in size among cryogenic calorimetric experiments, CUORE provides a promising setting for the study of exotic throughgoing particles. Using the first tonne year of CUORE's exposure, we perform a search for hypothesized fractionally charged particles (FCPs), which are well-motivated by various standard model extensions and would have suppressed interactions with matter.

Paradoxical improvement in exercise tolerance and peak VO2 consumption after treatment with ivabradine and beta-blockers in a patient with mild dilated cardiomyopathy and inappropriate sinus tachycardia-a case report.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.

Not all pancreatic cystic lesions are the same: lesson from a case with three different coexisting neoplasms.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

Primary pulmonary meningioma mimicking a carcinoid tumor in a middle-aged female.

A 46-year-old female complained of cough and dyspnea. A chest X-ray and CT scan showed a solitary subpleural pulmonary nodule in the left upper lobe. Surgical resection was performed.

Influence of indole acetic acid, arginine and mango fruit waste biochar on nutrients, chlorophyll contents and antioxidants of Fenugreek in salt affected soil.

Salinity stress disrupts water uptake and nutrient absorption, causing reduced photosynthesis, stunted growth, and decreased crop yields in plants. The use of indole acetic acid (IAA), arginine (AN), and mango fruit waste biochar (MFWB) can be effective methods to overcome this problem. Indole acetic acid (IAA) is a natural auxin hormone that aids cell elongation and division, thereby increasing plant height and branching.

Harnessing CRISPR interference to resensitize laboratory strains and clinical isolates to last resort antibiotics.

The global race against antimicrobial resistance requires novel antimicrobials that are not only effective in killing specific bacteria, but also minimize the emergence of new resistances. Recently, CRISPR/Cas-based antimicrobials were proposed to address killing specificity with encouraging results. However, the emergence of target sequence mutations triggered by Cas-cleavage was identified as an escape strategy, posing the risk of generating new antibiotic-resistance gene (ARG) variants.

Crystal structure of Au-pseudocarbyne(C).

Carbyne-related materials permit exploring the potentially extraordinary properties of this long-sought but still elusive carbon allotrope. However, accurate understanding of these materials is challenging. Here we report the crystal structure of a Au-pseudocarbyne, a representative of a possible new family of materials consisting of sp-hybridized carbon chains and stabilizing metal atoms.

Reduced ATP turnover during hibernation in relaxed skeletal muscle.

Hibernating brown bears, due to a drastic reduction in metabolic rate, show only moderate muscle wasting. Here, we evaluate if ATPase activity of resting skeletal muscle myosin can contribute to this energy sparing. By analyzing single muscle fibers taken from the same bears, either during hibernation or in summer, we find that fibers from hibernating bears have a mild decline in force production and a significant reduction in ATPase activity.

Influence of androgen receptor on bone health in transgender adults: insights from the COMET study.

Purpose: Previous studies show that transgender and gender-diverse (TGD) individuals, especially those assigned male at birth (AMAB), often have low bone mineral density (BMD) before beginning gender-affirming hormone therapy (GAHT). The reasons for this are not fully understood, and the potential role of androgen receptor (AR) polymorphisms - known to affect bone density in the general population - has not been explored. This study aims to assess the impact of AR polymorphisms on bone health in the TGD population.

Enhanced cyanophycin accumulation in diazotrophic cyanobacterium through random mutagenesis and tailored selection under varying phosphorus availability.

This study explored a sustainable alternative to the Haber-Bosch process by enhancing production of nitrogen-rich polymer cyanophycin (CGP) in the diazotrophic cyanobacterium Nostoc sp. PCC7120. Applying UV-mutagenesis followed by canavanine selection, we isolate an initial mutant with enhanced CGP accumulation.

Exploring the Phenomenon of Victim Blaming Toward Women With an Intimate Partner Violence Experience and the Role of Empathy.

Women who have experienced intimate partner violence (IPV) often encounter victim blaming from the general population, where individuals attribute responsibility to the victim's behavior for the violent episode. This phenomenon is influenced by levels of empathy, with lower empathy correlating with a higher likelihood of blaming women exposed to partner violence. Two studies were conducted.

Tail Fin Regeneration in Zebrafish: The Role of Non-canonical Crosstalk Between STAT3 and Vitamin D Pathway.

Stat3 is a transcription factor with a key role in cell proliferation and migration. Using the zebrafish line we showed that the genetic ablation results in a marked decrease of tail fin regrowth, demonstrating that this transcription factor is fundamental in the regeneration process. Stat3 activity is finely modulated by post-translational modifications that occur in several residues of the protein (i.

Words before pictures: the role of language in biasing visual attention.

Background: The present study investigated whether semantic processing of word and object primes can bias visual attention using top-down influences, even within an exogenous cueing framework. We hypothesized that real words and familiar objects would more effectively bias attentional engagement and target detection than pseudowords or pseudo-objects, as they can trigger prior knowledge to influence attention orienting and target detection.

Methods: To examine this, we conducted two web-based eye-tracking experiments that ensured participants maintained central fixation on the screen during remote data collection.

The determination of patient-based experiences with smartphone-based report of awake bruxism using a diary.

Objectives: In recent years, a smartphone-based ecological momentary assessment (EMA) approach for assessing awake bruxism (AB) has attracted growing interest, both in clinical and research settings. The present study was designed to investigate subjects' experience using an EMA-based smartphone application to detect factors that could hamper or facilitate its use for clinical and research purposes.

Can brain network connectivity facilitate the clinical development of disease-modifying anti-Alzheimer drugs?

The preclinical phase of Alzheimer's disease represents a crucial time window for therapeutic intervention but requires the identification of clinically relevant biomarkers that are sensitive to the effects of disease-modifying drugs. Amyloid peptide and tau proteins, the main histological hallmarks of Alzheimer's disease, have been widely used as biomarkers of anti-amyloid and anti-tau drugs. However, these biomarkers do not fully capture the multiple biological pathways of the brain.
