Type A aortic dissection during diagnostic coronary angiography in normal coronary arteries: A case report.

Key Clinical Message: Aortic dissection is one of the rare complication of coronary angiography. The main treatment underlies surgical intervention however; management should be done with patient's decision.

Abstract: Coronary angiography (CA) is a widely utilized diagnostic procedure used to evaluate blood flow through the coronary arteries and detect coronary artery disease (CAD).

Land Premium Effects of Urban Rail Transit and the Associated Policy Insights for TOD: A Case of Ningbo, China.

With considerable investments, mainly from local government budgets, the construction and operation of urban rail transit (URT) can exert significant spillover effects on the surrounding land use and land prices. In particular, China's local governments are actively committed to developing their URT systems and promoting large-scale transit-oriented development (TOD) projects under the public land leasing policy. However, the connection between the land premium effects and TOD policy and practice is still lacking, particularly in the local government contexts, which exhibit significant policy and spatial heterogeneity.

Role of Built Environments on Physical Activity and Health Promotion: A Review and Policy Insights.

As urbanization and motorization continue worldwide, various health issues have emerged as a burden between individuals, families and governments at all levels. Under the prevalence of chronic disease, this review synthesizes research on the impact of the various built environments on the multiple health outcomes from a methodological and mechanistic perspective. Besides, it attempts to provide useful planning and policy implications to promote physical activity and health benefits.

COVAN Leading to ESKD Despite Minimal COVID Symptoms.

We report a case of dialysis dependence in a patient with COVID-19-associated nephropathy (COVAN) who had minimal respiratory manifestations. A 25-year-old man with a history of multiple sclerosis in remission presented with mild dyspnea due to COVID-19 pneumonia and was found to have rapidly worsening kidney function. He only required nasal cannula and was able to be weaned off within a few days.

Curing the incurable: A case of refractory vasospastic angina.

Vasospastic angina (VSA) is the spasm of coronary arteries causing transient myocardial ischemia. VSA is commonly managed with antispasmodic medications including calcium-channel blockers (CCB) and nitrates. When vasospasm is refractory to conventional medications, unconventional treatment modalities may be used for symptomatic relief (Tandon et al.

Extended spectrum beta lactamase producing eustachian valve infective endocarditis.

Endocarditis is an infection of the endocardium caused by a multitude of bacteria, including , viridans streptococci, S. bovis, or S. epidermidis, among others.

[Control Models and Effect Evaluation of Air Pollution in Jing-Jin-Ji Urban Agglomeration].

Controlling air pollution in the Jing-jin-ji urban agglomeration (JJJUA), the most seriously polluted area in China, is related to the integrated development strategy for the region. Based on the national and regional implementation of air pollution control measures in recent years, the hierarchical cross-regional multi-directional linkage (HCML) air pollution prevention and control model was applied in this study. The effect of air pollution control was evaluated by monitoring the pollutants, SO, NO, PM, PM, O, and CO, at 112 monitoring sites in 13 cities in 2014-2015.

Preimplantation-stage stem cells induce long-term allogeneic graft acceptance without supplementary host conditioning.

Hematopoietic stem cells have been successfully employed for tolerance induction in a variety of rodent and large animal studies. However, clinical transplantation of fully allogeneic bone marrow or blood-borne stem cells is still associated with major obstacles, such as graft-versus-host disease or cytoreductive conditioning-related toxicity. Here we show that when rat embryonic stem cell-like cells of WKY origin are injected intraportally into fully MHC-mismatched DA rats, they engraft permanently (>150 days) without supplementary host conditioning.
