Gate dielectrics are essential components in nanoscale field-effect transistors (FETs), but they often face significant instabilities when exposed to harsh environments, such as radioactive conditions, leading to unreliable device performance. In this paper, we evaluate the performance of ultrascaled transition metal dichalcogenide (TMD) FETs equipped with vacuum gate dielectric (VGD) as a means to circumvent oxide-related instabilities. The nanodevice is computationally assessed using a quantum simulation approach based on the self-consistent solutions of the Poisson equation and the quantum transport equation under the ballistic transport regime.

Use of Immunostimulants in Shrimp Farming-A Bioeconomic Perspective.

Animals (Basel)

January 2025

Immunology & Vaccinology Group, Centro de Investigaciones Biológicas del Noroeste (CIBNOR), Av. Instituto Politécnico Nacional 195, Playa Palo de Santa Rita Sur, La Paz 23096, Mexico.

Aquaculture is the fastest-growing food industry worldwide because it allows faster intensive production in a limited space and short time. However, the trade-off of this production scheme has led to infectious disease outbreaks that harm food production with economic impacts. Immunostimulants have entered the industry to fight against diseases by enhancing the immune system and conferring better protection against pathogens.

CCL5 Induces a Sarcopenic-like Phenotype via the CCR5 Receptor.

Antioxidants (Basel)

January 2025

Laboratory of Muscle Pathology, Fragility and Aging, Department of Biological Sciences, Faculty of Life Sciences, Universidad Andres Bello, Santiago 8370146, Chile.

Sarcopenia corresponds to a decrease in muscle mass and strength. CCL5 is a new myokine whose expression, along with the CCR5 receptor, is increased in sarcopenic muscle. Therefore, we evaluated whether CCL5 and CCR5 induce a sarcopenic-like effect on skeletal muscle tissue and cultured muscle cells.

Occurrence of Intersex in the Marine Mussel (Mollusca: Bivalvia): Does Gonadal Parasitism Play a Role?

Biology (Basel)

January 2025

Instituto de Ciencias Marinas y Limnológicas, Universidad Austral de Chile, Independencia 631, Valdivia 5090000, Chile.

Intersexuality is a reproductive phenomenon that occurs in some gonochoric species and refers to the simultaneous presence of both male and female gametes within the same individual. Although this phenomenon has been reported in various invertebrate species, many aspects remain poorly understood, especially in marine mussels. However, it has been suggested that the prevalence of parasites within populations could induce the occurrence of intersex animals.

An Exploration of the Cellular Microenvironment of the Female Pig Urethra: Translational Insights for Urological Research.

Biology (Basel)

January 2025

Escuela de Medicina Veterinaria, Facultad de Ciencias de la Vida, Universidad Andres Bello, República 239 3° Piso, Santiago 8370146, Chile.

Urinary incontinence is a widespread issue, particularly among women, with effective treatments remaining elusive. The pig, and especially the female pig, stands as a promising animal model for the study of this condition, due to its anatomical similarities to humans. The aim of this study was to explore the largely uncharted muscular structure of the female pig urethra, linking urethral muscle dysfunction to incontinence.

We used otolith chemistry to test and complement current hypotheses regarding habitat use and connectivity between sub-populations in Area 48 of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Sagittal otoliths from 45 fish sampled near the South Orkney Islands were analysed. Their elemental (Li, Na, Mg, Cr, Mn, Sr, Sn, and Ba relative to Ca) and isotopic (δO and δC) signatures were examined in both the nuclear and marginal regions, representing juvenile and adult stages.

: Aging involves a series of changes in non-pathological age-related conditions, some of which impact the cognitive functioning of older adults. Executive functions are cognitive skills that are often affected in this process, although they have been shown to improve after physical exercise interventions. This protocol aims to describe the procedures that will be carried out in a systematic literature review, including a meta-analysis of the effects of resistance interventions on the main dimensions of executive function in cognitively healthy older adults compared to active or passive control groups.

Ready-to-eat (RTE) foods are the most common sources of transmission. Whole-genome sequencing (WGS) enhances the investigation of foodborne outbreaks by enabling the tracking of pathogen sources and the prediction of genetic traits related to virulence, stress, and antimicrobial resistance, which benefit food safety management. The aim of this study was to evaluate the efficacy of WGS in the typing of 16 strains isolated from refrigerated foods in Chile, highlighting its advantages in pathogen identification and the improvement of epidemiological surveillance and food safety.

January 2025

Exercise Applied Physiology Laboratory, Biomedical Department, Research Center in High Altitude Medicine and Physiology, Faculty of Health Sciences, University of Antofagasta, Antofagasta, Chile.

Amoebas are characterized by their unique ability to exist both as free-living organisms and, occasionally, as parasites within host tissues, earning them the designation 'amphizoic amoebae'. While amoebic infections are less prevalent, their health impact can be tremendous, leading to several diseases. In low-income countries, poor sanitation and socioeconomic conditions significantly increase the risk of amoebic infections, particularly E.
