Revisiting secondary model features for describing the shoulder and lag parameters of microbial inactivation and growth models.

The Baranyi and Geeraerd models are two of the most reliable models for the description of, respectively, microbial growth and inactivation. They are defined as a system of differential equations, whose algebraic solution can describe the microbial response during isothermal conditions, especially when combined with suitable secondary models. However, there are still large uncertainties regarding the best functions to use as secondary models for the lag phase duration (λ) and the shoulder length (S).

Accuracy and clinical applicability of plasma tau 181 and 217 for Alzheimer's disease diagnosis in a memory clinic cohort.

Plasma tau phosphorylated at threonine 181 (p-tau181) and 217 (p-tau217) have demonstrated high accuracy for Alzheimer's disease (AD) diagnosis, defined by CSF/PET amyloid beta (Aβ) positivity, but most studies have been performed in research cohorts, limiting their generalizability. We studied plasma p-tau217 and p-tau181 for CSF Aβ status discrimination in a cohort of consecutive patients attending an academic memory clinic in Spain (July 2019-June 2024). All patients had CSF AD biomarkers performed as part of their routine clinical assessment.

Artificial cell-free system for the sustainable production of acetoin from bioethanol.

The present work introduces and validates an artificial cell free system for the synthesis of acetoin from ethanol, representing a greener alternative to conventional chemical synthesis. The one pot multi-enzymatic system, which employs pyruvate decarboxylase from Zymobacter palmae (ZpPDC), alcohol dehydrogenase from Saccharomyces cerevisiae (ScADH), and NADH oxidase from Streptococcus pyogenes (SpNOX), achieves nearly 100 % substrate conversion and reaction yield within 6 h under optimal conditions (pH 7.5, enzyme activities: ZpPDC 100 U·mL, ScADH 50 U·mL, SpNOX 127 U·mL, and 1 mM NAD).

HeberNasvac: Development and Application in the Context of Chronic Hepatitis B.

Unlabelled: The immune system plays a central role in controlling acute hepatitis B infection and in patients resolving chronic hepatitis B (CHB). Given that 221 million (75%) of CHB patients reside in low- and middle-income countries, the development of a vaccine with therapeutic properties represents a rational and cost-effective approach more than a romantic endeavor. This review systematically analyzes the key variables related to the safety, efficacy, and effectiveness of CHB treatments.

Empowering lives: How deinstitutionalization and community living improve the quality of life of individuals with intellectual and developmental disabilities.

Background: The number of people with intellectual and developmental disabilities (IDD) living in residential settings has not changed substantially in recent years in Spain. To change this situation the project "My House: A Life in the Community" aims to promote the transition of individuals with IDD and high support needs into community settings.

Aims: This paper deepens the understanding of the underlying mechanisms responsible for the changes observed in the process of deinstitutionalization.

Cross-sectional study of the perceived wellbeing of children in palliative care.

Objective: To describe the perceived wellbeing (pWB) and the psychological characteristics of young people with life-limiting and life-threatening conditions (LLTCs).

Methods: We conducted a cross-sectional study in young people aged 8 years or older with collection of data on demographic and disease-related variables from the health records. In the psychological evaluation, we collected data on emotion regulation, cognitive strategies and risk of depression and anxiety, in addition to the assessment of the pWB through a visual analogue scale.

Hemodynamic Management guided by the Hypotension Prediction Index in Abdominal Surgery: A Multicenter Randomized Clinical Trial.

Background: Postoperative acute kidney injury (AKI) after major abdominal surgery leads to poor outcomes. The Hypotension Prediction Index (HPI) may aid in managing intraoperative hemodynamic instability. This study assessed if HPI-guided therapy reduces moderate-to-severe AKI incidence in moderate-to-high-risk elective abdominal surgery patients.

Pacing system analyzers to guide conduction system pacing implantation procedures: A comparison study of intracardiac and surface signals with an electrophysiology recording system.

Background: Left bundle branch area pacing (LBBAP) needs confirmation of left conduction system capture assessed by testing of different electrical parameters. Guidelines recommend the use of an electrophysiology recording system (EP-RS) to guide conduction system pacing procedures. However, some experienced centers perform LBBAP procedures without an EP-RS.

Rickettsia sibirica mongolitimonae Infections in Spain and Case Review of the Literature.

Rickettsia sibirica mongolitimonae is an emerging cause of tickborne rickettsiosis. Since the bacterium was first documented as a human pathogen in 1996, a total of 69 patients with this infection have been reported in the literature. Because of the rising rate of R.

transcription factors regulate promoter activity by a universal, homeostatic mechanism.

Transcription factors (TFs) may activate or repress gene expression through an interplay of different mechanisms, including RNA polymerase (RNAP) recruitment, exclusion, and initiation. TFs often have drastically different regulatory behaviors depending on promoter context and interacting cofactors. However, the detailed mechanisms by which each TF affects transcription and produce promoter-dependent regulation is unclear.

Foramen tympanicum: tomographic study of a large cohort of Europeans.

Purpose: The foramen tympanicum (FT) is an anatomical variation of the tympanic part of the temporal bone located in the anteroinferior part of the external auditory pore (EAP) and posteromedial to the temporomandibular joint (TMJ). The FT is most often asymptomatic, but it can be symptomatic in rare cases. The prevalence of FT varies widely in the literature.

Tracing metals in Mediterranean and Atlantic Sardina pilchardus: Unveiling impacts on food safety.

This study evaluates the concentration of metals and trace elements (Al, Cd, Cu, Fe, Li, Pb, Zn) in the muscle tissue of Sardina pilchardus from three northeast Atlantic localities (Lisbon, Canary Islands, Rabat) and two western Mediterranean sites (Málaga, Cartagena) to assess food safety and environmental impact. A total of 100 sardines were sampled between January and June 2019, with specimens collected, homogenized by size and weight, and analyzed for metal content using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Results show significant geographical variation in metal concentrations, with Cartagena exhibiting the highest levels due to industrial and urban activities, while the Canary Islands had the lowest, likely influenced by geographical isolation and stringent environmental regulations.

Optimizing a Novel Smartphone App to Prevent Postpartum Depression Adapted From an Evidence-Based Cognitive Behavioral Therapy Program: Qualitative Study.

Background: Low-income pregnant patients are at high risk of postpartum depression (PPD). Mothers and Babies (MB) is a cognitive behavioral therapy-based program that prevents up to 50% of de novo PPD when provided in person to low-income Spanish- and English-speaking people who are pregnant without depression. MB is limited by the need for trained personnel to support it.

Unveiling the Mechanism of Lurbinectedin's Action and Its Potential in Combination Therapies in Small Cell Lung Cancer.

Lurbinectedin is a selective inhibitor of oncogenic transcription approved for the treatment of adult patients with metastatic small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy. Preclinical data provide evidence for lurbinectedin exerting its actions in a unique manner that involves oncogenic transcription inhibition, DNA damage, reshaping of the tumor microenvironment, and inducing anticancer immunity. Understanding the mechanism of action (MoA) has facilitated the rational combination of lurbinectedin and anticancer therapies with complementary modes of action, in order to obtain synergistic effects that could potentially lead to improved efficacy.
