Further research confirmed that ferroptosis was triggered by aluminum in PC12 cells by means of activating the oxidative damage signaling pathway, which was displayed as inhibition of the cysteine/glutamate antiporter system (system Xc-), causing the depletion of cellular glutathione (GSH) and inactivation of glutathione peroxidase (GSH-PX) eventually lead to accumulation of reactive oxygen species (ROS). Taken together, ferroptosis was a means of neuronal death induced by aluminum and oxidative damage may be its underlying mechanism, which also provided some new clues to potential target for the intervention and therapy of AD.
To investigate the efficacy of inspiratory muscle training (IMT) on respiratory functions, respiratory muscle strength, and asthma symptoms in asthmatic children.
In a randomized placebo-controlled assessor-blinded study, 34 children with asthma were randomized to receive either the IMT at 40% of the maximal inspiratory pressure (IP
) for 20 min/session, thrice/week, over 12 consecutive weeks (IMT group;
= 17) or placebo IMT at 5% of IP
(placebo group;
= 17). Additionally, both groups received the conventional respiratory rehabilitation (CRR) program. Outcome measurements performed pre- and post-treatment, included respiratory functions [forced expiratory volume at the first second (FEV
), forced vital capacity (FEV), and FEV
/FVC], respiratory muscle strength [represented by IP
and maximal expiratory pressure (EP
), and asthma control test (ACT).
At a significance level adjusted to
<.008, there were significant post-treatment differences between the IMT and placebo groups in FEV
(
=.003), FVC (
=.001), FEV
/FVC (
=.004), IP
(
=.002), EP
(
=.004), and ACT (
=.001) adjusted to the pretreatment values, in favor of the IMT group.
Incorporation of IMT in the CRR program for children with asthma can improve respiratory function, enhance respiratory muscle strength, and improve children's perception of asthma symptoms.

Here we describe a metastatic Merkel cell carcinoma patient with a severe acute respiratory syndrome coronavirus 2 infection while receiving pembrolizumab. Case presentation A 66-year-old man, with a metastatic Merkel cell carcinoma receiving pembrolizumab, presented with fever. Chest computed tomography (CT) showed pulmonary ground-glass opacities, suggesting viral or immuno-related etiology. On day 7, the patient was hospitalized due to dyspnea and worsening of the radiological findings. Real time polymerase chain reaction (RT-PCR) testing confirmed COVID-19. The patient developed acute respiratory distress syndrome and acute kidney injury. Hydroxychloroquine was administered for 5 days, but discontinued after supraventricular extrasystoles. Clinical improvement allowed the patient's discharge after 81 days of hospitalization. Conclusion A careful evaluation of oncologic patients receiving immunotherapy during the COVID-19 pandemic is of utmost importance.Recent studies have reported the crucial role of stanniocalcin-2 (STC2) in hepatocellular carcinoma; however, its role in head and neck squamous cell carcinoma (HNSCC) remains elusive. In this study, microRNA-206 (miR-206) was predicted to target STC2 gene. The study herein aimed to elucidate the effect of miR-206 on HNSCC by targeting STC2. STC2 was highly expressed in HNSCC tissues and cells. By targeting STC2, miR-206 decreased mRNA and protein expression of STC2. Importantly, our study showed that miR-206 blocked the Akt signaling pathway by inhibiting STC2. Intriguingly, our data from in vitro and in vivo experiments suggested that miR-206 overexpression led to decreased cell proliferation and increased cell apoptosis and autophagy, as well as suppressed tumor growth; whereas, STC2 silencing reversed the effects of miR-206 inhibitor on those biological behaviors. In this study, we investigated the antioncogenic effect of miR-206 on HNSCC by targeting STC2, and highlighted miR-206/STC2 aixs as potential therapeutic targets for HNSCC.Dietary patterns have been associated with breast cancer (BC) in Argentina. However, little evidence exists relating the inflammatory potential of diet and BC in Latin American countries and how this may relate to rurality. The aim of the present study was to evaluate the association between the Dietary Inflammatory Index (DII®) and BC considering urbanization contexts in Córdoba, Argentina. A frequency-matched case-control study (317 BC cases, 526 controls) was conducted from 2008 through 2016. DII scores were computed based on dietary intake assessed by a validated food frequency questionnaire. NE 52-QQ57 research buy Multi-level logistic regression models were fit to evaluate the association between DII and BC, following adjustment for age, body mass index, age at menarche, number of children, smoking habits, socio-economic status and family history of BC as first-level covariates and urbanization level as the contextual variable. Increasing DII score showed significant positive associations with BC risk (ORtertile3vs.tertile1 1.34; 95%CI 1.05, 1.70). The association was stronger in overweight and obese women (ORtertile3vs.tertile1 1.98; 95%CI 1.86, 2.10). The DII effect on BC was higher with increased urbanization. A pro-inflammatory diet, reflected by higher DII scores, was positively associated with BC, especially in overweight women and with increased urbanization.
Hydrogen sulfide (H
S) has antihypertension and anti-inflammatory effects, and its endogenous-generation key enzyme cystathionine γ lyase (CSE) is expressed in CD4
T cells. However, the role of CD4
T-cell endogenous CSE/H
S in the development of hypertension is unclear.
Peripheral blood lymphocytes were isolated from hypertensive patients or spontaneously hypertensive rats, then H
S production and expression of its generation enzymes, cystathionine β synthase and CSE, were measured to determine the major H
S generation system changes in hypertension. Mice with CSE-specific knockout in T cells (conditional knockout, by CD4
mice hybridization) and CD4 null mice were generated for investigating the pathophysiological relevance of the CSE/H
S system.
In lymphocytes, H
S from CSE, but not cystathionine β synthase, responded to blood pressure changes, supported by lymphocyte CSE protein changes and a negative correlation between H
S production with systolic blood pressure and diastolic blood pressure, but positive correlation with the serum level of interleukin 10 (an anti-inflammatory cytokine).
