Liver is the central organ responsible for whole-body metabolism, and its constituent hepatocytes are the major players that carry out liver functions. Although they are highly differentiated and rarely divide, hepatocytes re-enter the cell cycle following hepatic loss due to liver damage or injury. …

Despite early stagnation in success rates for percutaneous coronary intervention for chronic total occlusion with the traditional antegrade wiring approach, the introduction of dissection/re-entry techniques and the retrograde approach opened new avenues for operators to tackle more complex occlusio …

Terminally differentiated cells of the nervous system have long been considered to be in a stable non-cycling state and are often considered to be permanently in G0. Exit from the cell cycle during development is often coincident with the differentiation of neurons, and is critical for neuronal func …

The study comprised 30 cases. Technical success was 97%. A small, quickly resolved extravasation was the only device related complication. These results are in line with the systematic review which identified 16 studies using the Pioneer RED, reporting a technical success rate of 87.4-100% (median = …

Aberrant neuronal cell cycle re-entry (CCR) is a phenomenon that precedes and may mechanistically lead to a majority of the neuronal loss observed in Alzheimer's disease (AD). Recent developments concerning the regulation of aberrant neuronal CCR in AD suggest that there are potential intracellular …

Endovascular reconstruction of the femoral and popliteal arteries is replacing femoral-popliteal bypass. This is made possible by subintimal recanalization to manage long chronic total occlusions. Re-entry into the true lumen is the most challenging step in this process. This article summarizes the …

Chronological aging is by far the strongest risk factor for age-related dementia and Alzheimer's disease. Senescent cells accumulated in the aging and Alzheimer's disease brains are now recognized as the keys to describing such an association. Cellular senescence is a classic phenomenon characterize …

Of the monomorphic ventricular tachycardias, there are 4 specific tachycardias related to the Purkinje system: 1) idiopathic verapamil-sensitive fascicular ventricular tachycardia (FVT); 2) non-re-entrant FVT; 3) bundle branch re-entry and interfascicular re-entry; and 4) Purkinje-mediated VT in str …

The localization in the jaw and the clinical situation are crucial for the decision which second-stage procedure should be applied.

RVI mapping allows localization of multiple regions susceptible to re-entry and may help guide VT ablation. RVI mapping does not require the induction of arrhythmia and may result in less ablated myocardial volumes with fewer ablation sites.

Septal hypertrophy and cell cycle re-entry in AD

Our findings show that neuronal cell cycle re-entry enhances AD-related neuropathological features in AppNLF mice and highlight our unique AD mouse model for studying the pathogenic role of aberrant cell cycle re-entry in AD.

Altered INa kinetics synergize powerfully with reduced INa amplitude to promote P2R-induced arrhythmias in BrS in the absence of Ito, establishing a robust mechanistic link between altered INa kinetics and the P2R-mediated arrhythmia mechanism.

Coronary chronic total occlusions (CTOs) are a commonly encountered lesion. These present in a diverse patient population with variable anatomy. Technical success rates of ~90% are achievable for CTO lesions in centers with appropriate expertise. Many lesions can be crossed with wire-based technique …

The purpose of this report is to review the evidence-based guidelines regarding the changing of surgical attire upon re-entry to the operating room or the ambulatory care environment in the acute care setting.

This paper provides an overview of maternity information technology (IT) in Britain, questioning the usability, effectiveness and cost efficiency of the current models of implementation of electronic maternity records. UK experience of hand-held paper obstetric notes and computerized records reveals …

Sporadic Alzheimer's disease (AD) exclusively affects elderly people. Using direct conversion of AD patient fibroblasts into induced neurons (iNs), we generated an age-equivalent neuronal model. AD patient-derived iNs exhibit strong neuronal transcriptome signatures characterized by downregulation o …

Eighty-three per cent of elite athletes returned to sport following ACL reconstruction, while 5.2% sustained a graft rupture. Most athletes who returned to sport performed comparably with matched, uninjured controls. This information may assist in guiding expectations of athletes and clinicians foll …

Cardiac optogenetics is an emergent research area involving the delivery of light-sensitive proteins (opsins) to excitable heart tissue to enable optical modulation of cardiac electrical function. Optogenetic stimulation has many noteworthy advantages over conventional electrical methods, including …

Aortoiliac occlusive disease in patients who are poor surgical candidates requires innovative strategies in endovascular surgery. We present a case of a 59-year-old gentleman with significant medical comorbidities and chronic limb-threatening ischemia secondary to a chronically occluded left-to-righ …

To maintain tissue homeostasis, cells transition between cell cycle quiescence and proliferation. An essential G1 process is minichromosome maintenance complex (MCM) loading at DNA replication origins to prepare for S phase, known as origin licensing. A p53-dependent origin licensing checkpoint norm …

In treating post-dissection TAA, entry closure by TEVAR is sometimes insufficient, owing to persistent retrograde flow into the FL from abdominal or iliac re-entries. Adjunctive techniques are needed to close these distal re-entries to obtain complete FL exclusion, especially in rupture cases. Recen …

The purpose of this empirical study is to analyze modalities of announcing the end of attempts at in vitro ferti-lization to women who, for various reasons, were not able to have a child after several trials. What are the problems physicians face when, in the course of their work, they make these an …

Findings demonstrate the relevance of intersectionality theory in HIV care with Black men involved in criminal justice system. Incorporating a social-ecological perspective into intersectionality framework could be useful in theoretical and empirical research. Disenfranchised communities may particu …

In our daily practice in public hospitals, we are regularly confronted with the paradox of helping patients, who do not ask for help. Although the French law is clearly defined to allow us to treat patients suffering from psychiatric conditions, who are unable to give their consent, it is not the ca …

We recognize that many of the issues raised are not simple. Our proposal calls for the same thoughtful deliberation applied in other settings to be brought to bear on reproductive health care. Some have already tried alternative approaches. In Albuquerque, New Mexico, a university hospital neonatolo …

The present paper deals with the basic aspects, influences and elements that constitute Informed Consent seeing it as a process and not only as an administrative format. Both the patient-physician relationship, as well as the research subject-investigator relationship, should be seen in the same man …

Breast reconstruction operations have been on the rise over the last two decades; with recent advances in medical practice, different options of breast reconstruction have been readily available. However, it is challenging for patients to grasp the knowledge and digest differences, advantages, and d …

Measures need to be taken to ensure adequacy of pre-operative counseling in patients undergoing robotic surgery. Misconceptions on benefits and risks of robotic surgery should be cleared before decision on the surgical access and approach.

In robotic surgery we believe in the necessity to follow three arrangements to make the IC more complete. Integrate the information already present in the informed consent with data on the surgeon's experience in RS, the number of procedures of the department and the regional map of expertises by pr …
