External auditory canal cancer is a rare disease which can be treated by surgery or chemoradiation. The most common histological type is squamous cell carcinoma, but rare types such as adenocarcinoma have been reported and are thought to be derived from the ceruminous glands. Here, we present a case of ceruminous adenocarcinoma, not otherwise specified (NOS) in the external auditory canal. A 72-year-old woman was referred to our department with discomfort due to a mass in the external ear canal. No typical symptoms of malignancy, such as pain or bleeding, were noted at the initial examination. The patient underwent a total excision under local anesthesia as a diagnostic treatment. She was diagnosed with ceruminous adenocarcinoma, NOS based on the results of immunostaining of the excised specimen, and is currently being followed up as an outpatient. Adenocarcinoma is thought to originate from the cerumen glands of the ear canal and the lack of specific symptoms may make it difficult to differentiate it from benign tumors. Although adenocarcinoma, NOS has been reported in the head and neck region, there have been no reported cases occurring in the external ear canal, and to the best of our knowledge, this is the first report.

An attitude change perspective represents a central line of research in the smoking literature. This line of research focuses on influencing individuals' attitudes toward smoking in order to alleviate the negative outcomes of smoking and to achieve positive smoking behaviours. This line of research, however, does not explain why attitudes toward cigarette smoking are a weak predictor of cigarette smoking, an indication of a smoking paradox. The current study introduces two domain-general factors to explore this smoking paradox.

We used an online survey and collected data from American subjects (

 = 328) via a crowdsourcing platform, Amazon Mechanical Turk, in 2018.

We found that the association between attitude toward smoking and the likelihood of smoking is significantly weaker when individuals perceive a low probability of risk and/or believe that this probable risk will only occur in the distant future, after many years. These results suggest that smoking may not be consistent with attitude because individuals perceive low probability of risk and/or they temporally discount the occurrence of this probable risk.

The results suggest that novel strategies that incorporate the concepts of perceived risk probability and temporal discounting of the probable risk are needed for smoking cessation.

Similar to C-reactive protein (CRP), AAT is an acute phase reactant, meaning that blood levels rise in response to inflammation, injury or infection. Testing AAT levels is essential in the diagnosis of AATD; however, the presence of inflammation at the time of AATD testing can provide a false 'normal' level reading of the patient's baseline AAT levels. Researchers from a US-wide screening program for AATD found that a large number of individuals with AATD variants (particularly with the PI*MZ genotype) presented with elevated CRP levels (≥5 mg/L), suggesting the presence of inflammation. Using a series of calculations, the relationship between AAT and CRP levels was characterized and found to be genotype specific. We have developed a publicly available, easy-to-use online calculator (PredictAAT) that enables the instant calculation of predicted baseline AAT levels in patients exhibiting elevated CRP levels that accounts for specific AATD genotype. There is a need to raise awareness of the importance of simultaneous determination of AAT and CRP levels to aid the accurate diagnosis of patients with AATD. The PredictAAT calculator is therefore a valuable tool for physicians to enhance early disease diagnosis and individualize treatment.Juvenile idiopathic arthritis-associated uveitis is rare in the Japanese population. In this article, we report a child whose macular edema was controlled for years after cataract surgery with adalimumab, and reviewed 26 Japanese patients in the literature. In this case report, a 4-year-old boy developed band keratopathy, posterior iris synechiae, and complicated cataract in both eyes. Oral prednisolone prescribed at another hospital was discontinued due to high intraocular pressure in both eyes as a steroid responder. At the age of 5 years, he started oral methotrexate 8 mg weekly for recurrent bilateral iridocyclitis and then underwent lensectomy with core vitrectomy in both eyes. Planned intraocular lens implantation was cancelled at surgery because the anterior vitreous had severe inflammatory opacity with diffuse retinal edema in both eyes. Due to persistent macular edema in both eyes 5 months postoperatively, at the age of 6 years, he began to use adalimumab injection 20 mg every 2 weeks. The macular structure depicted by optical coherence tomography became normal in 2 months. At final visit at the age of 11 years, he had the best-corrected visual acuity of 0.8 in the right eye and 0.4 in the left eye, with adalimumab 40 mg every 2 weeks and methotrexate 8 mg weekly. In conclusion, macular edema persistent despite oral methotrexate after cataract surgery could be controlled for long term by adalimumab in a child with juvenile idiopathic arthritis. In the Japanese literature, only 26 additional cases with juvenile idiopathic arthritis-associated uveitis have been reported so far.Efficient cell factories are the core of industrial biotechnology. In recent years, synthetic biology develops rapidly, and more and more modified microbial cell factories are employed in industrial biotechnology. ATP plays vital roles in biosynthesis, metabolism regulation, and cellular maintenance. Regulating cellular ATP supply can effectively modify cellular metabolism. This paper presents a review of recent studies on the regulation of the intracellular ATP supply and its application in industrial biotechnology. Detailed strategies for regulating the ATP supply and the resulting impact on bioproduction are introduced. It is observed that regulating the cellular ATP supply can provide great possibilities for making microbial cells into efficient factories. Future perspectives for further understanding the function of ATP are also discussed.

Approximately 15% of saphenous vein grafts (SVGs) occlude during the first year after coronary artery bypass graft surgery (CABG) despite aspirin use. The POPular CABG trial (The Effect of Ticagrelor on Saphenous Vein Graft Patency in Patients Undergoing Coronary Artery Bypass Grafting Surgery) investigated whether ticagrelor added to standard aspirin improves SVG patency at 1 year after CABG.

In this investigator-initiated, randomized, double-blind, placebo-controlled, multicenter trial, patients with ≥1 SVGs were randomly assigned (11) after CABG to ticagrelor or placebo added to standard aspirin (80 mg or 100 mg). The primary outcome was SVG occlusion at 1 year, assessed with coronary computed tomography angiography, in all patients that had primary outcome imaging available. A generalized estimating equation model was used to perform the primary analysis per SVG. The secondary outcome was 1-year SVG failure, which was a composite of SVG occlusion, SVG revascularization, myocardial infarction in myocarot reduce SVG occlusion at 1 year after CABG.

Biomaterials and stem cell transplantation are promising treatments for functional recovery in SCI. Seven patients with acute complete SCI diagnosed by a combination of methods were included in the study, and different lengths (2.0-6.0 cm) of necrotic spinal cord tissue were surgically cleaned under intraoperative neurophysiological monitoring. Subsequently, NeuroRegen scaffolds loaded with autologous bone marrow mononuclear cells (BMMCs) were implanted into the cleaned site. All patients participated in 6 months of rehabilitation and at least 3 years of clinical follow-up. No adverse symptoms associated with stem cell or functional scaffold implantation were observed during the 3-year follow-up period. Additionally, partial shallow sensory and autonomic nervous functional improvements were observed in some patients, but no motor function recovery was observed. Magnetic resonance imaging suggested that NeuroRegen scaffold implantation supported injured spinal cord continuity after treatment. These findings indicate that implantation of NeuroRegen scaffolds combined with stem cells may serve as a safe and promising clinical treatment for patients with acute complete SCI. However, determining the therapeutic effects and exact application methods still requires further study.Tools for tuning transcription in mammalian cells have broad applications, from basic biological discovery to human gene therapy. While precise control over target gene transcription via dosing with small molecules (drugs) is highly sought, the design of such inducible systems that meets required performance metrics poses a great challenge in mammalian cell synthetic biology. Important characteristics include tight and tunable gene expression with a low background, minimal drug toxicity, and orthogonality. Here, we review small-molecule-inducible transcriptional control devices that have demonstrated success in mammalian cells and mouse models. Most of these systems employ natural or designed ligand-binding protein domains to directly or indirectly communicate with transcription machinery at a target sequence, via carefully constructed fusions. Example fusions include those to transcription activator-like effectors (TALEs), DNA-targeting proteins (e.g. dCas systems) fused to transactivating domains, and recombinases. Similar to the architecture of Type I nuclear receptors, many of the systems are designed such that the transcriptional controller is excluded from the nucleus in the absence of an inducer. Techniques that use ligand-induced proteolysis and antibody-based chemically induced dimerizers are also described. Collectively, these transcriptional control devices take advantage of a variety of recently developed molecular biology tools and cell biology insights and represent both proof of concept (e.g. targeting reporter gene expression) and disease-targeting studies.Uncontrolled hypertension is a leading contributor to cardiovascular disease. A cluster-randomized trial in 16 primary care clinics showed that 12 months of home blood pressure telemonitoring and pharmacist management lowered blood pressure more than usual care (UC) for 24 months. We report cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, hospitalized heart failure, coronary revascularization, and cardiovascular death) and costs over 5 years of follow-up. In the telemonitoring intervention (TI group, n=228), there were 15 cardiovascular events (5 myocardial infarction, 4 stroke, 5 heart failure, 1 cardiovascular death) among 10 patients. In UC group (n=222), there were 26 events (11 myocardial infarction, 12 stroke, 3 heart failure) among 19 patients. The cardiovascular composite end point incidence was 4.4% in the TI group versus 8.6% in the UC group (odds ratio, 0.49 [95% CI, 0.21-1.13], P=0.09). Including 2 coronary revascularizations in the TI group and 10 in the UC group, the secondary cardiovascular composite end point incidence was 5.
