Physical exercise requires integrated autonomic and cardiovascular adjustments to maintain homeostasis. We aimed to observe acute posture-related changes in blood pressure, and apply a portable noninvasive monitor to measure the heart index for detecting arrhythmia among elite participants of a 246-km mountain ultra-marathon. Nine experienced ultra-marathoners (8 males and 1 female) participating in the Run Across Taiwan Ultra-marathon in 2018 were enrolled.

As a broad-spectrum anticancer drug, cisplatin is widely used in the treatment of tumors in various systems. Unfortunately, several serious side effects of cisplatin limit its clinical application, the most common of which are nephrotoxicity and ototoxicity. Studies have shown that cochlear hair cell degeneration is the main cause of cisplatin-induced hearing loss.

Article Synopsis
  • The study investigates testosterone and precursor levels in the testicular interstitial fluid (TIF) of men with azoospermia and their significance for sperm retrieval success.
  • Out of 37 TIF samples, men with non-obstructive azoospermia (NOA) showed higher testosterone and precursor concentrations compared to those with obstructive azoospermia (OA), particularly in untreated cases.
  • Successful sperm retrieval in NOA patients was linked to specific hormonal profiles, highlighting distinct testosterone biosynthesis pathways that may help improve reproductive outcomes.

Article Synopsis
  • Methamphetamine (MA) is a widely abused stimulant that causes neurotoxicity through oxidative stress and apoptosis, particularly affecting dopaminergic neurons.
  • The study investigated how MA influences various proteins related to neuroprotection (Nrf2), mitochondrial dynamics (Mfn1, Drp1), and apoptosis (Caspase 3) in brain tissue of MA users and a rat model.
  • Results showed that levels of Nrf2 and Mfn1 decreased while levels of Drp1, Cyt-c, and Caspase 3 increased in MA users, suggesting that Nrf2 may be crucial in mediating the harmful effects of MA on neurons through oxidative stress and mitochondrial dysfunction.

Unraveling the mechanism of chirality transfer across length scales is crucial to the rational development of functional materials with hierarchical chirality. The key obstacle is the lack of structural information, especially at the mesoscopic level. We report herein the structural identification of helical covalent organic frameworks (COFs) with hierarchical chirality, which integrate molecular chirality, channel chirality, and morphology chirality into one crystalline entity.

Objective This population-based cross-sectional study aimed to investigate the association between thyroid hormones and renal function in euthyroid Chinese individuals, as the relationship between thyroid hormones and renal function in this population remains unclear. Methods A total of 661 participants were included in the study after excluding individuals with thyroid diseases, incomplete clinical measurements, or those taking medications affecting thyroid function. Participants were categorized into three groups based on serum thyroid hormone and antibody levels.

The extensive use of mineral fertilizers has a negative impact on the environment, whereas wastewater and microalgal biomass can provide crops with nutrients such as nitrogen, phosphorus, and potassium, and have the potential to be used as a source of fertilizers in circular agriculture. In this study, a step-by-step resource utilization study of algae-containing wastewater generated from microalgae treatment of swine wastewater was carried out. When wheat seedlings were cultivated in the effluent after microalgae separation, the root fresh weight, seedling fresh weight, and total seedling length were increased by 3.

Hypokalemic Periodic Paralysis Type 2 (HOKPP2) is a rare autosomal dominant disorder characterized by recurrent episodes of muscle weakness, paralysis, and hypokalemia. In this case report, we present the clinical details of a 49-year-old female diagnosed with HOKPP2. Genetic testing revealed a heterozygous mutation in the Sodium Voltage-Gated Channel Alpha Subunit 4 ( gene, confirming the diagnosis of HOKPP2.

  • * A new nanoparticle named VP28-heparin was developed by conjugating heparin with an immuno-stealth protein, showcasing promising properties such as non-immunogenicity and a size that helps it evade rapid removal from circulation.
  • * In tests, VP28-heparin demonstrated improved anticoagulation effects compared to traditional heparin without negatively impacting platelet counts or causing severe side effects, making it a potentially safer therapeutic option.

: Paraquat (PQ) plays an important role in agricultural production due to its highly effective herbicidal effect. However, it has led to multiple organ failure in those who have been poisoned, with damage most notable in the lungs and ultimately leading to death. Because of little research has been performed at the genetic level, and therefore, the specific genetic changes caused by PQ exposure are unclear.

Background: SmeYZ is a constitutively expressed efflux pump in Stenotrophomonas maltophilia. Previous studies demonstrated that: (i) smeYZ inactivation causes compromised swimming, oxidative stress tolerance and aminoglycoside resistance; and (ii) the ΔsmeYZ-mediated pleiotropic defects, except aminoglycoside susceptibility, result from up-regulation of entSCEBB'FA and sbiAB operons, and decreased intracellular iron level.

Objectives: To elucidate the modulatory role of SmeQ, a novel cytoplasmic protein, in ΔsmeYZ-mediated pleiotropic defects.

Arteriosclerosis, as the foundation for the development of cardiovascular diseases, is influenced by disturbances in lipid metabolism. Extensive research has consistently shown a correlation between conventional lipid parameters, arteriosclerosis, and cardiovascular diseases. Guidelines highlight the importance of targeting low-density lipoprotein cholesterol (LDL-C) for primary and secondary prevention of cardiovascular diseases, with reducing LDL-C remaining the primary lipid-lowering strategy.

Background: Non-valvular atrial fibrillation (NVAF) is associated with increased stroke in elderly populations, yet anticoagulant therapy is underutilized. We analyzed clinical characteristics and anticoagulation treatment rates of elderly NVAF patients hospitalized in Dali, China, to identify potential contributing factors.

Methods: We collected data for 155 elderly patients with NVAF aged ≥60 years, from July 01, 2020, to December 31, 2021.

Nanobodies (Nbs) have great potential in immunoassays due to their exceptional physicochemical properties. With the immortal nature of Nbs and the ability to manipulate their structures using protein engineering, it will become increasingly valuable to understand what structural features of Nbs drive high stability, affinity, and selectivity. Here, we employed an anti-quinalphos Nb as a model to illustrate the structural basis of Nbs' distinctive physicochemical properties and the recognition mechanism.

  • The study aimed to assess the sperm retrieval rate in men with persistent azoospermia after chemotherapy, focusing on the impact of cyclophosphamide equivalent dose (CED).
  • Out of 23 patients who had undergone chemotherapy, only 47% successfully retrieved testicular spermatozoa, with lower rates observed in those exposed to alkylating agents.
  • The findings suggest that higher CED correlates with reduced chances of viable sperm retrieval, highlighting the need for informed counseling for affected patients before surgical interventions.

Protein tyrosine phosphatase 1B (PTP1B) is a key negative regulator of the insulin signaling pathway, which is a potential therapeutic target for the treatment of type 2 diabetes mellitus (T2DM). In this study, we identified several PTP1B inhibitors with high activity by using high-throughput virtual screening and in vitro enzyme inhibition activity verification strategies. Among them, baicalin was first reported as a selective mixed inhibitor of PTP1B, with IC value of 3.
