The Molecular Mechanisms of Lipopolysaccharides Tolerance
Lipopolysaccharides (LPSs) are complex molecules found in the outer membrane of Gram-negative bacteria, which are composed of three main regions: lipid A, core oligosaccharide, and O antigen.

Hypertensive Heart Failure
Hypertension (HTN) is the leading cause of cardiovascular disease and premature death worldwide, which largely surpasses other important factors of mortality such as smoking and metabolic diseases. HTN is the most important risk factor for heart failure (HF) development, with recent evidence indicating that HTN is present in 76% of incident HF cases, and the lifetime risk of HF is almost twice as high in people with HTN as in those with normal blood pressure (BP).

Enhanced Drug Penetration and Retention in Airway Mucosa
Airway mucus is a complex viscoelastic gel mainly composed of water, glycoproteins, lipids, enzymes, minerals, etc. Among them, glycoprotein is the main factor determining mucus-gel-like rheology. Airway mucus forms a protective barrier by secreting mucin, which represents the absorption barrier, especially for more lipophilic drugs. It rapidly clears the drug from the airways through physiological mucus clearance mechanisms, so the drug does not remain in the lungs or reach the airway epithelial tissue for a long time.

Pathogenesis of Rosacea
Rosacea is a chronic inflammatory skin condition characterized by skin sensitivity, flushing, centrofacial erythema, papules, and pustules. The condition has been classified into four subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular rosacea. Rosacea mainly affects the cheeks, nose, chin, and forehead. It causes flushing or transient erythema, persistent erythema, phymatous changes, papules, pustules, and telangiectasias. The eyes can also be affected by rosacea, causing conditions such as conjunctivitis, blepharitis, and, rarely, keratitis. Physical changes in the face due to rosacea can cause embarrassment, leading to reduced quality of life and self-esteem.

Bioprinting in Renal Regenerative Medicine
In this new era of technological advancement, three-dimensional (3D) printing has emerged in medicine, promising to revolutionize surgical practices. Three-dimensional printing could be defined as “translating” a digital image into a 3D solid object by printing consecutive thin layers of materials. The fusion of tissue engineering and 3D printing has given rise to bioprinting. This technique employs biocompatible printers and "bio-ink" to create intricate tissue structures, while the complete fabrication of functional organs remains a research objective. 3D bioprinting has already shown promising results, especially in the field of microfluidic devices with the development of tissues demonstrating proximal tubules, glomerulus, and tubuloinerstitium functions. Such models could be applied in renal disease modeling and during drug development for nephrotoxicity investigation.

Impact of Heavy Metals on Glioma Tumorigenesis
Heavy metals are capable of generating reactive oxygen, which plays a key role in various pathological mechanisms. Alteration of the homeostasis of heavy metals could cause the overproduction of reactive oxygen species and induce DNA damage, lipid peroxidation, and the alteration of proteins. A large number of studies have shown that iron, cadmium, lead, nickel, chromium, and mercury levels were significantly elevated in patients affected by gliomas.

Regulatory ILC2—Role of IL-10 Producing ILC2 in Asthma
Innate lymphoid cells (ILC) are a family of lineage-negative cells that are are proposed to be critical drivers of inflammation at mucosal interfaces. KLRG1+ILC2 have the capacity to produce the anti-inflam-matory cytokine IL-10. ILC2 respond to microenvironmental cues, including retinoic acid (RA), IL-2, IL-4, IL-10, and IL-33, as well as neuropeptide mediators such as neuromedin-U (NMU), prompting a shift towards IL-10 and away from T2 cytokine production. In contrast, TGF-β attenuates IL-10 production by ILC2. Immune regulation provided by IL-10+ILC2s holds potential significance for the management of T2 inflammatory conditions.

Beneficial Mechanisms of Physical Exercise in Alzheimer’s Disease
Physical exercise has emerged as a promising non-pharmacological intervention for Alzheimer’s disease (AD), with demonstrated effects on promoting neurogenesis, activating neurotrophic factors, reducing Aβ aggregates, minimizing the formation of neurofibrillary tangles (NFTs), dampening inflammatory processes, mitigating oxidative stress, and improving the functionality of the neurovascular unit (NVU). Overall, the neuroprotective effects of exercise are not singular, but are multi-targets.

ECMO Management in Severely Hypothermic Cardiac Arrest Patients
Accidental hypothermia, defined as an unintentional drop of the body core temperature below 35 °C, is one of the causes of cardiocirculatory instability and reversible cardiac arrest. Currently, extracorporeal life support (ECLS) rewarming is recommended as a first-line treatment for hypothermic cardiac arrest patients. The aim of the ECLS rewarming is not only rapid normalization of core temperature but also maintenance of adequate organ perfusion. Veno-arterial extracorporeal membrane oxygenation (ECMO) is a preferred technique due to its lower anticoagulation requirements and potential to prolong circulatory support. Although highly efficient, ECMO is acknowledged as an invasive treatment option, requiring experienced medical personnel and is associated with the risk of serious complications.
