Spatiotemporal ATF3 Expression Determines VSMC Fate in Abdominal Aortic Aneurysm.

Background: Abdominal aortic aneurysm (AAA) is a catastrophic disease with little effective therapy, likely due to the limited understanding of the mechanisms underlying AAA development and progression. ATF3 (activating transcription factor 3) has been increasingly recognized as a key regulator of cardiovascular diseases. However, the role of ATF3 in AAA development and progression remains elusive.

Solutal Marangoni effect determines bubble dynamics during electrocatalytic hydrogen evolution.

Understanding and manipulating gas bubble evolution during electrochemical water splitting is a crucial strategy for optimizing the electrode/electrolyte/gas bubble interface. Here gas bubble dynamics are investigated during the hydrogen evolution reaction on a well-defined platinum microelectrode by varying the electrolyte composition. We find that the microbubble coalescence efficiency follows the Hofmeister series of anions in the electrolyte.

N-acetylcysteine ameliorates erectile dysfunction in rats with hyperlipidemia by inhibiting oxidative stress and corpus cavernosum smooth muscle cells phenotypic modulation.

Hyperlipidemia is a major risk factor for erectile dysfunction (ED). Oxidative stress and phenotypic modulation of corpus cavernosum smooth muscle cells (CCSMCs) are the key pathological factors of ED. N-acetylcysteine (NAC) can inhibit oxidative stress; however, whether NAC can alleviate pathological variations in the corpus cavernosum and promote erectile function recovery in hyperlipidemic rats remains unclear.

Ablation of Basic Leucine Zipper Transcription Factor ATF-Like Potentiates Estradiol to Induce Atopic Dermatitis.

Background: Atopic dermatitis (AD) is an inflammatory and immune skin disorder. Basic leucine zipper transcription factor ATF-like (BATF) plays a key role in regulating the differentiation and functions of lymphocytes. However, the mechanism underlying the transcriptional regulation of BATF on AD is still not well understood.

Comparison of color Doppler ultrasonography and computed tomography angiography (CTA) and computed tomography venography (CTV) in the diagnosis of arteriovenous thrombosis after simultaneous pancreas-kidney transplantation: a retrospective diagnostic accuracy study.

Background: Simultaneous pancreas-kidney transplantation is an important treatment approach for diabetic renal insufficiency, but pancreatic arteriovenous thrombosis is among the early serious surgical complications that can lead to graft loss and even be fatal. Ultrasound is considered to be a safe and non-invasive approach, but it is often affected by intestinal gas interference and operator proficiency, partial thromboses may be easily missed. Computed tomography angiography (CTA) and computed tomography venography (CTV) are highly accurate but radiative, requiring the use of contrast agents.

removal of stones in donor kidneys by pyelotomy prior to renal transplantation: a single-center case series.

Background: Donors with incidentally discovered asymptomatic renal stones was considered a relative contraindication to the kidney donation because of a potential increased morbidity risk for renal transplant recipients. Stone clearance from the donors should be done before donation to ensure safety of the recipient. This study aimed to observe the safety and efficacy of kidney transplantation from donors with nephrolithiasis who received pyelolithotomy before transplantation.

Two-Dimensional Room-Temperature Magnetic Nonstoichiometric FeSe Nanocrystals: Controllable Synthesis and Magnetic Behavior.

Two-dimensional (2D) magnetic materials have attracted significant attention for promising applications in energy-saving logic and robust memory devices. However, most 2D magnets discovered so far typically feature drawbacks for practical applications due to low critical temperatures. Herein, we synthesize ultrathin room-temperature (RT) magnetic FeSe nanoflakes via the space-confined chemical vapor deposition method.

Methods: Seventy-nine RTRs treated in our hospital from February 2015 to February 2016 were interviewed for allergic diseases by using a standard questionnaire.

A PSCA/PGRN-NF-κB-Integrin-α4 Axis Promotes Prostate Cancer Cell Adhesion to Bone Marrow Endothelium and Enhances Metastatic Potential.

Distant metastasis, predominantly to bone, is the leading cause of morbidity and mortality in prostate cancer. However, the mechanisms underlying prostate cancer metastases remain unknown. Prostate cancer cells exhibited discrete adhesion to bone marrow endothelial cells (BMEC), resulting in osteotropic metastasis.
