In the last decades, progress in neuroimaging techniques and cerebrospinal fluid assays has enabled the characterization of several Alzheimer's disease (AD) biomarkers. This knowledge has shifted the conceptualization of AD from a clinical-pathological construct, where its diagnosis required the presence of dementia with distinct pathologic features, toward a clinical-biological one that recognizes AD as a pathological continuum with a clinical picture that ranges from normal cognition to a dementia stage. Specifically, AD is now divided into three stages: preclinical (abnormal biomarkers and no or only subtle cognitive impairment), mild cognitive impairment or prodromal AD (abnormal pathophysiological biomarkers and episodic memory impairment), and dementia (abnormal biomarkers and clear cognitive and functional impairment)...

Robotic assisted surgery system is the most advanced minimally invasive surgical platform in the world, and this system has been widely used in cardiac surgery, urology surgery, gynecology surgery and general surgery. Although the application of this system was relative late in esophageal surgery, it has been developing vigorously. According to the research progress and practical experience in the world, robot assisted minimally invasive esophagectomy (RAMIE) has the same safety and effectiveness as traditional open esophagectomy (OE) and thoracoscopic laparoscopic esophagectomy (TLE)...

To gain insight into the mechanism of sarcopenia and the protective effect of melatonin, the gastrocnemius muscles of young (3-4 months), early-aged (12 months), and old-aged (24 months) wild type C57BL/6J female mice, were examined by magnetic resonance and microscopy. Locomotor activity, lactate production and nuclear apoptosis were also assessed. The results support the early onset of sarcopenia at 12 months of age, with reduction of muscle fibers' number, muscle weight/body weight ratio, lactate, and locomotor activity...

Obesity and type 2 diabetes (T2D) increase the risk for cardiomyopathy, which is the presence of ventricular dysfunction in the absence of underlying coronary artery disease and/or hypertension. As myocardial energy metabolism is altered during obesity/T2D (increased fatty acid oxidation and decreased glucose oxidation), we hypothesized that restricting myocardial glucose oxidation in lean mice devoid of the perturbed metabolic milieu observed in obesity/T2D would produce a cardiomyopathy phenotype, characterized via diastolic dysfunction...

It has been suggested that in environments where there is greater fear of litigation, resident autonomy and education is compromised. Our aim was to examine failure rates on American Board of Surgery (ABS) examinations in comparison with medical malpractice payments in 47 US states/territories that have general surgery residency programs. We hypothesized higher ABS examination failure rates for general surgery residents who graduate from residencies in states with higher malpractice risk. We conducted a retrospective review of five-year (2010-2014) pass rates of first-time examinees of the ABS examinations...

The start of the cue is often used to initiate the feature window used to control motor imagery (MI)-based brain-computer interface (BCI) systems. However, the time latency during an MI period varies between trials for each participant. Fixing the starting time point of MI features can lead to decreased system performance in MI-based BCI systems. To address this issue, we propose a novel correlation-based time window selection (CTWS) algorithm for MI-based BCIs. Specifically, the optimized reference signals for each class were selected based on correlation analysis and performance evaluation...

Due to the high ability of cadmium to cross the blood-brain barrier, cadmium (Cd) causes severe neurological damages. Hence, the purpose of this study was to investigate the possible protective effect of Mangifera indica leaf extract (MLE) against Cd-induced neurotoxicity. Rats were divided into eight groups. Group 1 served as vehicle control group, groups 2, 3 and 4 received MLE (100, 200, 300 mg /kg b.wt, respectively). Group 5 was treated with CdCl2 (5 mg/kg b.wt). Groups 6, 7 and 8 were co-treated with MLE and CdCl2 using the same doses...

BACKGROUND: Heart failure education programs are not standardized. The best form of education is unclear. We evaluated whether addition of a novel tablet application to nurse practitioner (NP) education was superior to NP education alone in reducing 30-day readmission after heart failure hospitalization. METHODS: From 2/2015-3/2016, patients admitted to a quaternary academic center with primary diagnosis of heart failure were randomized to (1) treatment- NP education plus tablet application (interactive conditional logic program that flags patient questions to medical staff) or (2) control- NP education...

BACKGROUND: Stereotactic radiosurgery (SRS) of brain metastases (BM) is recommended in oligometastatic scenarios as a less toxic treatment alternative to whole-brain radiotherapy. Recent findings support SRS for patients with multiple (>3) BM. Furthermore, advances in MR imaging have facilitated the detection of very small BM, as advances in SRS technology have facilitated the highly conformal and simultaneous treatment of multiple target lesions. OBJECTIVE: To compare efficacy and toxicity of repeated frameless robotic SRS of up to 10 simultaneous BM through a single-center prospective randomized trial...

Immune cells are important components of the tumor microenvironment and influence tumor growth and evolution at all stages of carcinogenesis. Notably, it is now well established that the immune infiltrate in human tumors can correlate with prognosis and response to therapy. The analysis of the immune infiltrate in the tumor microenvironment has become a major challenge for the classification of patients and the response to treatment. The co-expression of inhibitory receptors such as Program Cell Death Protein 1 (PD1; also known as CD279), Cytotoxic T Lymphocyte Associated Protein 4 (CTLA-4), T-Cell Immunoglobulin and Mucin Containing Protein-3 (Tim-3; also known as CD366), and Lymphocyte Activation Gene 3 (Lag-3; also known as CD223), is a hallmark of T cell exhaustion...

Ziziphus spina-christi (L.), a traditional Arabian medicinal herb, has been used by Egyptians (Bedouin and Nubian) to treat inflammatory symptoms and swellings, pain, and heat since long. We aimed to investigate whether Ziziphus spina-christi leaf extract (ZSCLE) exerted a myocardial and renal protective effect on mice in which sepsis had been induced with cecal ligation and puncture (CLP). Male C57BL/6 mice were divided randomly into six groups (n = 7): sham-operated group, sham-operated mice treated with ZSCLE (300 mg/kg), CLP-induced sepsis group, ZSCLE (100 mg/kg)-treated group, ZSCLE (200 mg/kg)-treated group, and ZSCLE (300 mg/kg)-treated group...
