Breathing difficulties and exertional dyspnea are frequently reported in hypermobile Ehlers-Danlos syndrome (hEDS); however, they are not clearly explained. An impaired proprioception or the addition of a cognitive task could influence ventilatory control. How can the perception of lung volume be measured? Is lung volume perception impaired in hEDS patients? Is the breathing control impaired during a cognitive task in hEDS patients? A device was developed to assess the accuracy of lung volume perception in patients with hEDS and matched control subjects. In the second step, ventilation was recorded in both groups with and without a cognitive task. Two groups of 19 subjects were included. The accuracy of lung volume perception was significantly (P < 0.01) lower at 30% of inspired vital capacity in patients with hEDS in comparison to the control group, and they showed erratic ventilation (based on spatial and temporal criteria) when performing a cognitive task. These data support the influence of the proprioceptive deficit on ventilatory control in hEDS patients. These elements may help to understand the respiratory manifestations found in hEDS. Future research should focus on this relationship between lung volume perception and ventilation, and could contribute to our understanding of other pathologies or exercise physiology.Trial registration number: ClinicalTrials.gov, NCT05000151.
ABSTRACT: Maternal gut microbiome impairment has garnered attention for its potential role in influencing neurodevelopmental outcomes in offspring, especially in situations that increase brain vulnerability such as perinatal asphyxia (PA). Maternal microbiome and fetal brain interplay emerge as a critical link between maternal health and offspring neurodevelopment. This study aims to generate a model to assess the impact of maternal dysbiosis triggered by gestational antibiotic administration and PA on offspring neurodevelopment. Wistar rats were subjected to antibiotics in drinking water from the 11th gestational day until birth. On the 6th postnatal day, pups were subjected to PA/normoxia, resulting in four experimental groups: control-normoxia, antibiotics-normoxia, control-asphyxia, and antibiotics-asphyxia. Early-life behavioral tests were conducted between postnatal days 7 and 9. The initial antimicrobial cocktail (ampicillin, vancomycin, neomycin, clindamycin, amphotericin-B) led to an increased number of miscarriages, poor weight gain during pregnancy, reduced offspring weight, and changes in the maternal gut microbiome compared to control. Offspring presented impaired neurodevelopmental reflexes in both PA and antibiotic groups and increased hippocampal neuroinflammation. Due to these detrimental effects, a more pregnancy-safe antibiotic cocktail was used for a second experiment (ampicillin, vancomycin, neomycin, meropenem). This resulted in no miscarriages or pregnancy-weight loss but was still linked to gut microbiome disruption. PA impaired neurodevelopmental reflexes and increased neuroinflammation, effects amplified by antibiotic administration. These preliminary findings reveal the cumulative potential of maternal dysbiosis and PA on neurodevelopment impairment, emphasizing caution in gestational antimicrobial use. Further investigations should include offspring long-term follow-up and maternal behavior and integrate probiotics to counteract antibiotic effects.
LAY SUMMARY: This study investigates the impact of maternal gut microbiome disruptions caused by gestational antibiotic treatment and low oxygen exposure shortly after birth on the development of the rats' babies. We found that both antibiotic exposure and reduced oxygen levels led to changes in early behavior and increased inflammation of the nervous tissue in the baby rats. Although using a different, potentially safer antibiotic combination reduced pregnancy complications, it still changed the bacteria in the mother's gut and worsened early behavior. These findings show that antibiotics during pregnancy can affect the developing brain of baby rats and careful consideration should be used before prescribing them. Future research will explore longer-term effects and potential medicines.
Participants received 1 or 2 doses of placebo (normal saline) directly into the catheter lumen. Participants received the first dose at min 0, and the second dose (if needed) at min 90.
This is a randomized, placebo-controlled, double-blinded crossover study to test the following hypotheses: (1) In normal mid- to late pubertal girls without hyperandrogenism (HA), progesterone acutely suppresses waking LH pulse frequency more than sleep-associated LH pulse frequency; and (2) compared to normal mid- to late pubertal girls without HA, acute progesterone suppression of waking LH pulse frequency is impaired in mid- to late pubertal girls with HA. Studies will be performed in mid- to late pubertal girls (at least Tanner breast stage 3 but no more than 2 years postmenarcheal). Subjects will complete two 18-hour Clinical Research Unit (CRU) admissions in separate menstrual cycles. Immediately before and during the first CRU admission, either oral micronized progesterone (0.8 mg/kg/dose) or placebo (randomized) will be given at 0700, 1500, 2300, and 0700 h. During the CRU admission, blood will be obtained every 10 minutes through an indwelling iv catheter from 1800 to 1200 h. This will allow full characterization of pulsatile LH secretion in addition to other hormone measurements. A second CRU admission (performed at least 2 months later given blood withdrawal limits) will be identical to the first except that placebo will exchanged for progesterone or vice versa (treatment crossover). The primary endpoint is LH pulse frequency while awake. (LH pulse frequency while asleep is an important secondary endpoint.) Results in pubertal girls without HA were recently published (Kim et al, J Clin Endocrinol Metab 2018;103:1112-1121). Data from girls with HA will be compared to recently-published results in girls without HA. Mean LH pulse frequency while awake will be analyzed via a hierarchical linear mixed model (HLMM). HA status (HA vs. non-HA), sleep status (wake vs. sleep), and treatment (progesterone vs. placebo) will represent fixed-effects, along with all associated interactions. Random effects will be used to account for hierarchical variance-covariance structure of the crossover study design. With regard to hypothesis testing, the association between HA status and wake LH pulse frequency will be evaluated via linear contrasts of HLMM least squares pulse frequency means. The differential impact of exogenous progesterone on wake LH pulse frequency in pubertal girls with and without HA (primary analysis) will be evaluated via the same testing method. Using published and preliminary data, we determined that, if 16 pubertal girls with HA complete both admissions, we should have at least an 80% chance of detecting a 0.2 pulse/hour differential effect of P4 on wake LH pulse frequency between the HA and the non-HA groups with a two-sided false positive rejection rate of no more than 0.05.
Patients receiving immunosuppressants, including IMURAN, are at increased risk of developing lymphoma and other malignancies, particularly of the skin. Physicians should inform patients of the risk of malignancy with IMURAN. As usual for patients with increased risk for skin cancer, exposure to sunlight and ultraviolet light should be limited by wearing protective clothing and using a sunscreen with a high protection factor.

Post-transplant

Renal transplant patients are known to have an increased risk of malignancy, predominantly skin cancer and reticulum cell or lymphomatous tumors. The risk of post-transplant lymphomas may be increased in patients who receive aggressive treatment with immunosuppressive drugs, including IMURAN. Therefore, immunosuppressive drug therapy should be maintained at the lowest effective levels. 

Rheumatoid Arthritis

Information is available on the risk of malignancy with the use of IMURAN in rheumatoid arthritis (see ADVERSE REACTIONS). It has not been possible to define the precise risk of malignancy due to IMURAN. The data suggest the risk may be elevated in patients with rheumatoid arthritis, though lower than for renal transplant patients. However, acute myelogenous leukemia as well as solid tumors have been reported in patients with rheumatoid arthritis who have received IMURAN. 

Inflammatory Bowel Disease

Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with IMURAN. These cases have had a very aggressive disease course and have been fatal. The majority of reported cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Some of the patients were treated with IMURAN as monotherapy and some had received concomitant treatment with a TNFα blocker at or prior to diagnosis. The safety and efficacy of IMURAN for the treatment of Crohn's disease and ulcerative colitis have not been established.

This study aims to evaluated the impact of poly(ε-caprolactone) (PCL) microspheres on the pharmacokinetics and pharmacodynamics (PopPK/PD) of 6-methylcoumarin (6MC). For this, PCL microspheres loaded with 6MC were prepared using the emulsification-evaporation method. Particle size, zeta potential, drug loading, and entrapment efficiency were characterised by dynamic light scattering and UV spectrophotometry. In vitro release and pharmacokinetics in Wistar rats were assessed for free and encapsulated 6MC. Anti-inflammatory activity was evaluated using the carrageenan-induced paw edoema model, with PopPK and PopPK/PD models developed. Microspheres showed diameters between 2.9 and 7.1 µm, zeta potentials of -10 to -15 mV, and drug loading of 0.24 mg/mg. Encapsulation efficiency was 45.5% to 75.9%. PopPK models showed enhanced absorption and distribution, with increased anti-inflammatory potency of encapsulated 6MC. PCL microspheres significantly improved the pharmacokinetic and pharmacodynamic profiles of 6MC, enhancing its therapeutic potential for lipophilic drugs.
Cerebral oxygen metabolism is altered in relapsing-remitting multiple sclerosis (RRMS), possibly a result of disease related cerebral atrophy with subsequent decreased oxygen demand. However, MS inflammation can also inhibit brain metabolism. Therefore, we measured cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) using MRI phase contrast mapping and susceptibility-based oximetry in 44 patients with early RRMS and 36 healthy controls. Cerebral atrophy and white matter lesion load were assessed from high-resolution structural MRI. Expanded Disability Status Scale (EDSS) scores were collected from medical records. The CMRO2 was significantly lower in patients (-15%, p = 0.002) and decreased significantly with age in patients relative to the controls (-1.35 µmol/100 g/min/year, p = 0.036). The lower CMRO2 in RRMS was primarily driven by a higher venous oxygen saturation in the sagittal sinus (p = 0.007) and not a reduction in CBF (p = 0.69). There was no difference in cerebral atrophy between the groups, and no correlation between CMRO2 and MS lesion volume or EDSS score. Therefore, the progressive CMRO2 decline observed before the occurrence of significant cerebral atrophy and despite adequate CBF supports emerging evidence of dysfunctional cellular respiration as a potential pathogenic mechanism and therapeutic target in RRMS.

WRKY transcription factors (TFs) can participate in plant biological stress responses and play important roles. SlWRKY80 was found to be differentially expressed in the Mi-1- and Mi-3-resistant tomato lines by RNA-seq and may serve as a key node for disease resistance regulation. This study used RNAi to determine whether SlWRKY80 silencing could influence the sensitivity of 'M82' (mi-1/mi-1)-susceptible lines to M. incognita. Further overexpression of this gene revealed a significant increase in tomato disease resistance, ranging from highly susceptible to susceptible, combined with the identification of growth (plant height, stem diameter, and leaf area) and physiological (soluble sugars and proteins; root activity) indicators, clarifying the role of SlWRKY80 as a positive regulatory factor in tomato defense against M. incognita. Based on this phenomenon, a preliminary exploration of its metabolic signals revealed that SlWRKY80 stimulates different degrees of signaling, such as salicylic acid (SA), jasmonic acid (JA), and ethylene (ETH), and may synergistically regulate reactive oxygen species (ROS) accumulation and scavenging enzyme activity, hindering the formation of feeding sites and ultimately leading to the reduction of root gall growth. To our knowledge, SlWRKY80 has an extremely high utilization value for improving tomato resistance to root-knot nematodes and breeding.

BACKGROUND: The pathogenesis of lower respiratory tract infections (LRTIs) has been demonstrated to be strongly associated with dysbiosis of respiratory microbiota. Scutellaria baicalensis, a traditional Chinese medicine, is widely used to treat respiratory infections. However, whether the therapeutic effect of S. baicalensis on LRTIs depends upon respiratory microbiota regulation is largely unclear.
PURPOSE: To investigate the potential effect and mechanism of S. baicalensis on the respiratory microbiota of LRTI mice.
METHODS: A mouse model of LRTI was established using Klebsiella pneumoniae or Streptococcus pneumoniae. Antibiotic treatment was administered, and transplantation of respiratory microbiota was performed to deplete the respiratory microbiota of mice and recover the destroyed microbial community, respectively. High-performance liquid chromatography (HPLC) was used to determine and quantify the chemical components of S. baicalensis water decoction (SBWD). Pathological changes in lung tissues and the expressions of serum inflammatory cytokines, including interleukin-17A (IL-17A), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), were determined by hematoxylin and eosin (H&E) staining and enzyme-linked immunosorbent assay (ELISA), respectively. Quantitative real-time PCR (qRT-PCR) analysis was performed to detect the mRNA expression of GM-CSF. Metagenomic sequencing was performed to evaluate the effect of SBWD on the composition and function of the respiratory microbiota in LRTI mice.
RESULTS: Seven main components, including scutellarin, baicalin, oroxylin A-7-O-β-d-glucuronide, wogonoside, baicalein, wogonin, and oroxylin A, were identified and their levels in SBWD were quantified. SBWD ameliorated pulmonary pathological injury and inflammatory responses in K. pneumoniae and S. pneumoniae-induced LRTI mice, as evidenced by the dose-dependent reductions in the levels of serum inflammatory cytokines, IL-6 and TNF-α. SBWD may exert a bidirectional regulatory effect on the host innate immune responses in LRTI mice and regulate the expressions of IL-17A and GM-CSF in a microbiota-dependent manner. K. pneumoniae infection but not S. pneumoniae infection led to dysbiosis in the respiratory microbiota, evident through disturbances in the taxonomic composition characterized by bacterial enrichment, including Proteobacteria, Enterobacteriaceae, and Klebsiella. K. pneumoniae and S. pneumoniae infection altered the bacterial functional profile of the respiratory microbiota, as indicated by increases in lipopolysaccharide biosynthesis, metabolic pathways, and carbohydrate metabolism. SBWD had a certain trend on the regulation of compositional disorders in the respiratory flora and modulated partial microbial functions embracing carbohydrate metabolism in K. pneumoniae-induced LRTI mice.
CONCLUSION: SBWD may exert an anti-infection effect on LRTI by targeting IL-17A and GM-CSF through respiratory microbiota regulation. The mechanism of S. baicalensis action on respiratory microbiota in LRTI treatment merits further investigation.
Ferroptosis is a nonapoptotic form of regulated cell death that has been reported to play a central role in cardiac ischemia‒reperfusion (I/R) injury. N-acetyltransferase 10 (NAT10) contributes to cardiomyocyte apoptosis by functioning as an RNA ac4c acetyltransferase, but its role in cardiomyocyte ferroptosis during I/R injury has not been determined. This study aimed to elucidate the role of NAT10 in cardiac ferroptosis as well as the underlying mechanism. The mRNA and protein levels of NAT10 were increased in mouse hearts after I/R and in cardiomyocytes that were exposed to hypoxia/reoxygenation. P53 acted as an endogenous activator of NAT10 during I/R in a transcription-dependent manner. Cardiac overexpression of NAT10 caused cardiomyocyte ferroptosis to exacerbate I/R injury, while cardiomyocyte-specific knockout of NAT10 or pharmacological inhibition of NAT10 with Remodelin had the opposite effects. The inhibition of cardiomyocyte ferroptosis by Fer-1 exerted superior cardioprotective effects against the NAT10-induced exacerbation of post-I/R cardiac damage than the inhibition of apoptosis by emricasan. Mechanistically, NAT10 induced the ac4C modification of Mybbp1a, increasing its stability, which in turn activated p53 and subsequently repressed the transcription of the anti-ferroptotic gene SLC7A11. Moreover, knockdown of Mybbp1a partially abolished the detrimental effects of NAT10 overexpression on cardiomyocyte ferroptosis and cardiac I/R injury. Collectively, our study revealed that p53 and NAT10 interdependently cooperate to form a positive feedback loop that promotes cardiomyocyte ferroptosis to exacerbate cardiac I/R injury, suggesting that targeting the NAT10/Mybbp1a/p53 axis may be a novel approach for treating cardiac I/R.
