The Role of Polarizability in Isoelectronic Ions: The Case of Pseudohalides.

Molecules

January 2025

Department of Chemistry "Ugo Schiff" and CSGI, University of Florence, 50019 Sesto Fiorentino, Italy.

Specific ion effects are widespread and have been studied for over a century, yet they remain poorly understood. Terms like "kosmotropes" and "chaotropes" are convenient rules of thumb but the frequent reversal of the Hofmeister series implies their limitations. Polarizability is often used to classify ions, with kosmotropes considered low in polarizability and chaotropes high.

Triply periodic minimal surfaces (TPMSs) are known for their smooth, fully interconnected, and naturally porous characteristics, offering a superior alternative to traditional porous structures. These structures often suffer from stress concentration and a lack of adjustability. Using laser powder bed fusion (LPBF), we have fabricated Inconel 625 sheet-based TPMS lattice structures with four distinct topologies: Primitive, IWP, Diamond, and Gyroid.

Laminated bamboo (LB), as a novel eco-friendly composite material with a high strength-to-weight ratio, has garnered increasing interest. However, there is a gap in comprehending the impact of size on the tensile properties of LB, particularly tensile strength and modulus. In contrast with conventional materials such as concrete and wood, which have specified specimen sizes and size effect factors to address performance variances linked to size, LB lacks such standards and references.

Citric Acid and Sodium Bicarbonate as an Alternative Carbon Dioxide Source for Mosquito Surveillance.

Insects

January 2025

Sydney Infectious Diseases Institute, Faculty of Medicine and Health, The University of Sydney, Camperdown, NSW 2006, Australia.

Most mosquito surveillance programs rely on traps baited with carbon dioxide (CO) to attract host-seeking mosquitoes. The source of CO, traditionally dry ice or gas cylinders, poses operational challenges, especially in remote locations. CO production from citric acid and sodium bicarbonate (NaHCO) using low-cost intravenous fluid bags ('acid traps') was evaluated in laboratory experiments.

Cellular Signaling of Amino Acid Metabolism in Prostate Cancer.

Int J Mol Sci

January 2025

School of Biology and Biological Engineering, South China University of Technology, University Town, Guangzhou 510006, China.

Prostate cancer is one of the most common malignancies affecting men worldwide and a leading cause of cancer-related mortality, necessitating a deeper understanding of its underlying biochemical pathways. Similar to other cancer types, prostate cancer is also characterised by aberrantly activated metabolic pathways that support tumour development, such as amino acid metabolism, which is involved in modulating key physiological and pathological cellular processes during the progression of this disease. The metabolism of several amino acids, such as glutamine and methionine, crucial for tumorigenesis, is dysregulated and commonly discussed in prostate cancer.

Human hematopoietic stem cells (HSCs) have traditionally been viewed as self-renewing, multipotent cells with enormous potential in sustaining essential steady state blood and immune cell production throughout life. Indeed, around 86% (10-10) of new cells generated daily in a healthy young human adult are of hematopoietic origin. Therapeutically, human HSCs have contributed to over 1.

Bile salt hydrolase (BSH), a probiotic-related enzyme with cholesterol-assimilating and anti-hypercholesterolemic abilities, has been isolated from intestinal bacteria; however, BSH activity of bacteria in bile-salt-free (non-intestinal) environments is largely unknown. Here, we aimed to identify BSH from non-intestinal and characterize its enzymatic function. We successfully isolated a plasmid-encoded () from , and the recombinant EfpBSH showed BSH activity that preferentially hydrolyzed taurine-conjugated bile salts, unlike the activity of known BSHs.

Jun, an Oncological Foe or Friend?

Int J Mol Sci

January 2025

Vascular Biology and Translational Research, Department of Pathology, School of Biomedical Sciences, Faculty of Medicine and Health, University of New South Wales, Sydney, NSW 2052, Australia.

Jun/JUN is a basic leucine zipper (bZIP) protein and a prototypic member of the activator protein-1 (AP-1) family of transcription factors that can act as homo- or heterodimers, interact with DNA elements and co-factors, and regulate gene transcription. Jun is expressed by both immune and inflammatory cells. Jun is traditionally seen as an oncoprotein that regulates processes involved in transformation and oncogenesis in human tumours.

The prevalence of infertility is increasing worldwide; poor nutrition, increased sedentary lifestyles, obesity, stress, endocrine-disrupting chemicals, and advanced age of childbearing may contribute to the disruption of ovulation and influence oocyte and sperm quality and overall reproductive health. Historically, infertility has been primarily attributed to female factors, neglecting the importance of male fertility; this has resulted in an incomplete understanding of reproductive health. Male factors account for 40-50% of infertility cases.

(1) Background: The incidence of gestational diabetes mellitus (GDM) is rising globally. The current evidence indicates that GDM, especially in conjunction with maternal overweight, can alter the composition of infants' gut microbiota, potentially increasing the risk of inflammatory diseases, metabolic disorders, and neurodevelopmental issues later in life. Probiotic supplantation early in life might establish eubiosis and mitigate future complications.

Recent interest in the diverse ecosystem of bacteria, fungi, parasites, and viruses that make up the skin microbiome has led to several studies investigating the microbiome in healthy skin and in a variety of dermatological conditions. An imbalance of the normal skin flora can cause some skin diseases, and current culture techniques are often unable to detect a microorganism to further our understanding of the clinical-microbiological correlates of disease and dysbiosis. Atopic dermatitis and rosacea are presentations that GPs often manage that may have an infective or microbiological component and can be challenging to treat.

A High-Precision Micro-Roll Forming Facility for Fuel Cell Metal Bipolar Plate Production.

Micromachines (Basel)

January 2025

School of Engineering, Deakin University, 75 Pigdons Rd., Waurn Ponds, Geelong, VIC 3216, Australia.

The metal bipolar plate is a critical component of the hydrogen fuel cell stack used in proton exchange membrane fuel cells. Bipolar plates must have high accuracy micro-channels with a high aspect ratio () between the channel depth and the half periodic width to achieve optimal cell performance. Conventional forming methods, such as micro-stamping, hydroforming, and rubber pad forming, cannot achieve these high ARs given that in these processes, material deformation is dominated by stretch deformation.

Exploring the Potential of Genome-Wide Hybridization Capture Enrichment for Forensic DNA Profiling of Degraded Bones.

Genes (Basel)

December 2024

Australian Centre for Ancient DNA, The Environment Institute, School of Biological Sciences, The University of Adelaide, Adelaide, SA 5000, Australia.

Unlabelled: In many human rights and criminal contexts, skeletal remains are often the only available samples, and they present a significant challenge for forensic DNA profiling due to DNA degradation. Ancient DNA methods, particularly capture hybridization enrichment, have been proposed for dealing with severely degraded bones, given their capacity to yield results in ancient remains.

Background/objectives: This paper aims to test the efficacy of genome-wide capture enrichment on degraded forensic human remains compared to autosomal STRs analysis.
