Safety of carotid artery stenting (CAS) in patients having carotid stenosis with coexistent unruptured intracranial aneurysms (UIAs) is rarely reported. Thus, we studied the 3-month outcome of CAS in the presence of coexistent UIAs in our institution.

A retrospective analysis of patients receiving CAS at our institution from September 2011 to December 2019 was carried out. Patients were stratified into 2 groups group of CAS with UIAs (CAS-UIA) and group of CAS without UIAs (CAS). The main complications within 3 months after stenting were TIA, ischemic stroke, symptomatic intracranial hemorrhage (sICH), rupture of UIAs, and death. The baseline characteristics and complications of the 2 groups were compared.

Five hundred fifty-six patients (CAS, n = 468; CAS-UIA, n = 88) were included and 604 stenting procedures were performed. More patients had hypertension in the CAS-UIA group (87.5 vs. 73.7%, p = 0.006). There was no significant difference in TIAs, ischemic stroke, sICH, and death within 3 months after stenting between the CAS and CAS-UIA groups. None of the 113 coexistent UIAs detected in 88 patients had aneurysm rupture within 3 months after CAS.

In our large cohort of CAS patients, coexistent UIAs are not uncommon. Stenting of a carotid artery in the presence of coexistent UIAs could be conducted safely. Together with 3-month dual antiplatelet therapy, CAS did not increase the rupture risk of the coexistent UIAs within 3 months.

The incidence of oral squamous cell carcinoma (OSCC) shows a constant increase, while the long-term outcome remains poor over the last decades. Radical oxygen and nitrogen species (RONS) - initially released by carcinogens, such as alcohol and tobacco, and later maintained by the tumor microenvironment - appear to be strongly associated to chronic inflammation, tumor induction, progression, and metastatic spread. The aim of this study was to evaluate the role of oxidative and nitrosative stress in primary OSCC compared to healthy tissue specimens and to identify their impact on tumor carcinogenesis.

In this basic research study, tissue samples of 30 patients with primary OSCC were evaluated for the expression of pAKT, pERK, 3-NT, NOS1, NOS3, MAPK1, and IP-8 by immunohistochemistry and RT-PCR and compared to those of a healthy control group (n = 30).

The results showed a significantly increased expression of pAKT (p < 0.001), pERK (p = 0.01), 3-NT (p = 0.039), NOS1 (p = 0.025), NOS3 (p = 0.046), and MAPK1 (p = 0.032) in OSCC tissue samples compared to healthy controls.

The results of this study prove the tested stable degradation products to be suitable for the detection of RONS in OSCC. Moreover, the significantly increased expression underlines the role of RONS in carcinogenesis of OSCC, suggests specific mechanisms of detection, and anticipates supplementary research.

To develop risk predictive models of postpartum stress urinary incontinence (SUI) for both primiparous and multiparous women.

From July 2016 to July 2017, 815 singleton pregnant women without incontinence before pregnancy who were 18 years or older and admitted to 2 hospitals in Shenzhen, China, were enrolled. Pregnancy-related data were collected at enrollment. Delivery information was obtained from electronic medical records. Telephone follow-up was conducted to investigate SUI at 6 weeks postpartum. Multivariable logistic regression analyses using stepwise selection were used to establish predictive models for postpartum SUI for all women, and separately for primiparous and multiparous. Internal validation of the models was performed with discrimination and calibration using a bootstrapping (1,000 resampling) method.

The analysis included 727 participants. The prevalence of postpartum SUI was 15.96% (116/727), 12.5% (49/393) for primiparous women and 20.1% (67/334) for multiparous women, with a signiof postpartum SUI for both primiparous and multiparous women. This approach may provide a useful tool for high-risk prediction of postpartum SUI before and after delivery.Strange as it may seem, von Kempelen's speaking machine from 1791 is the best result obtained in various attempts to build a mechanism similar to the speech apparatus, capable of producing a vocal signal. In this book discussion, we will illustrate von Kempelen's work, along with the attempts, across history, to build talking devices. We will highlight the 2 paths that have been followed over the centuries "vocal transport" and "artificial voice." The first case was a trick, because the voice was produced by a hidden subject and transported through an artifice to a head or a statue. The other path, that of research, has tried to imitate the phonatory apparatus to produce sequences of sounds somewhat similar to those that make up the speech chain. Which of the 2 paths led to the production of today's synthesized speech? The trick or the research? We will try to answer this question.

Numerous studies have documented the in vitro differentiation of human pluripotent stem cells (hPSCs) into kidney cells. Fewer studies have followed the fates of such kidney precursor cells (KPCs) inside animals, a more life-like setting. Here, we tested the hypothesis that implanting hPSC-derived KPCs into an in vivo milieu surgically engineered to be highly vascular would enhance their maturation into kidney tissues.

3D printed chambers containing KPCs were implanted into the thighs of adult immunodeficient mice. GDC-6036 In some chambers, an arterial and venous flow-through (AVFT) was surgically fashioned. After 3 weeks and 3 months, implants were studied by histology, using qualitative and quantitative methods.

After 3 weeks, chambers containing AVFTs were richer in small vessels than contralateral chambers without AVFTs. Glomeruli with capillary loops and diverse types of tubules were detected in all chambers. At 3 months, chambers contained only rudimentary tubules and glomeruli that appeared avascular. In chambers with AVFTs, prominent areas of muscle-like cells were also detected near tubules and the abnormal tissues immunostained for transforming growth factor β1.
