A human brain atlas of χ-separation for normative iron and myelin distributions.

Iron and myelin are primary susceptibility sources in the human brain. These substances are essential for a healthy brain, and their abnormalities are often related to various neurological disorders. Recently, an advanced susceptibility mapping technique, which is referred to as χ-separation (pronounced as "chi"-separation), has been proposed, successfully disentangling paramagnetic iron from diamagnetic myelin.

Ergonomics in Dermatologic Laser Procedures.

Due to working in static positions and use of repetitive movements over long periods of time, dermatologists are at increased risk of work-related musculoskeletal injury. Historically, studies on procedural ergonomics have focused on dermatologic surgery, however, laser procedures can also have a significant cumulative effect on physician posture. Here, we aim to highlight ergonomic challenges specific to dermatologic laser procedures and suggest areas of improvement in operating room organization, patient positioning, physician mechanics, and instrumentation.

Immunoglobulin class-switch recombination: Mechanism, regulation, and related diseases.

Maturation of the secondary antibody repertoire requires class-switch recombination (CSR), which switches IgM to other immunoglobulins (Igs), and somatic hypermutation, which promotes the production of high-affinity antibodies. Following immune response or infection within the body, activation of T cell-dependent and T cell-independent antigens triggers the activation of activation-induced cytidine deaminase, initiating the CSR process. CSR has the capacity to modify the functional properties of antibodies, thereby contributing to the adaptive immune response in the organism.

Sciatic nerve stimulation alleviates neuropathic pain and associated neuroinflammation in the dorsal root ganglia in a rodent model.

Background: Satellite glial cells (SGCs) in the dorsal root ganglia (DRG) play a pivotal role in the formation of neuropathic pain (NP). Sciatic nerve stimulation (SNS) neuromodulation was reported to alleviate NP and reduce neuroinflammation. However, the mechanisms underlying SNS in the DRG remain unclear.

Activity of botulinum neurotoxin X and its structure when shielded by a non-toxic non-hemagglutinin protein.

Botulinum neurotoxins (BoNTs) are the most potent toxins known and are used to treat an increasing number of medical disorders. All BoNTs are naturally co-expressed with a protective partner protein (NTNH) with which they form a 300 kDa complex, to resist acidic and proteolytic attack from the digestive tract. We have previously identified a new botulinum neurotoxin serotype, BoNT/X, that has unique and therapeutically attractive properties.

Recent Progress in the Applications of MXene-Based Materials in Multivalent Ion Batteries.

Multivalent-ion batteries have garnered significant attention as promising alternatives to traditional lithium-ion batteries due to their higher charge density and potential for sustainable energy storage solutions. Nevertheless, the slow diffusion of multivalent ions is the primary issue with electrode materials for multivalent-ion batteries. In this review, the suitability of MXene-based materials for multivalent-ion batteries applications is explored, focusing onions such as magnesium (Mg), aluminum (Al), zinc (Zn), and beyond.

Acoustofluidic Virus Isolation via Bessel Beam Excitation Separation Technology.

The isolation of viruses from complex biological samples is essential for creating sensitive bioassays that assess the efficacy and safety of viral therapeutics and vaccines, which have played a critical role during the COVID-19 pandemic. However, existing methods of viral isolation are time-consuming and labor-intensive due to the multiple processing steps required, resulting in low yields. Here, we introduce the rapid, efficient, and high-resolution acoustofluidic isolation of viruses from complex biological samples via Bessel beam excitation separation technology (BEST).

Enhanced In Vitro Recapitulation of In Vivo Liver Regeneration by Co-Culturing Hepatocyte Organoids with Adipose-Derived Mesenchymal Stem Cells, Alleviating Steatosis and Apoptosis in Acute Alcoholic Liver Injury.

Hepatocyte organoids (HOs) have superior hepatic functions to cholangiocyte-derived organoids but suffer from shorter lifespans. To counteract this, we co-cultured pig HOs with adipose-derived mesenchymal stem cells (A-MSCs) and performed transcriptome analysis. The results revealed that A-MSCs enhanced the collagen synthesis pathways, which are crucial for maintaining the three-dimensional structure and extracellular matrix synthesis of the organoids.

Monocytic Phagocytes in the Immunopathogenesis of Cytokine Storm Syndromes.

Cytokine storm syndromes (CSSs) are caused by a dysregulated host immune response to an inciting systemic inflammatory trigger. This maladaptive and harmful immune response culminates in collateral damage to host tissues resulting in life-threatening multisystem organ failure. Knowledge of the various immune cells that contribute to CSS pathogenesis has improved dramatically in the past decade.

Background: The benefits of HCV eradication on distinct recurrence patterns and long-term hepatic outcomes in patients with hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA) remain uncertain. This study aims to assess the impact of HCV eradication on HCC recurrence patterns and long-term hepatic outcomes after RFA and to identify predictors of recurrence in patients achieving sustained virological response (SVR).

Methods: We retrospectively enrolled 274 patients receiving RFA for HCV-related HCC, including 73 and 88 patients treated with interferon-based (IFN) and direct-acting antivirals (DAA) therapy, respectively.

Sero-Kinship: How Young People Living With HIV/AIDS Survive in Southeast Nigeria.

Research on the lived experiences of HIV survivors, including young people living with HIV, has primarily emphasized broader sociocultural concerns, such as stigmatization and cultural attitudes toward sexuality and gender, while giving less attention to the interconnectedness of these issues with the mental well-being of those affected by the illness. This study, drawing on relational ethnography including observations and interviews at four antiretroviral-administering healthcare facilities in Enugu State, southeast Nigeria, explores how young people living with HIV strive toward viral suppression and how they develop collaborative psychosocial support along with the global efforts in eradicating the HIV epidemic. We found that, in and between themselves, young people living with HIV weave for themselves a network of relationships, though discreetly, to foster and encourage survivorship.

Quantum modeling simulates nutrient effect of bioplastic polyhydroxyalkanoate (PHA) production in Pseudomonas putida.

Polyhydroxyalkanoates (PHAs) could be used to make sustainable, biodegradable plastics. However, the precise and accurate mechanistic modeling of PHA biosynthesis, especially medium-chain-length PHA (mcl-PHA), for yield improvement remains a challenge to biology. PHA biosynthesis is typically triggered by nitrogen limitation and tends to peak at an optimal carbon-to-nitrogen (C/N) ratio.
