Parkinson's disease (PD) is the second most common neurodegenerative disorder producing a variety of motor and cognitive deficits with the causes remaining largely unknown. The gradual loss of the nigrostriatal pathway is currently considered the pivotal pathological event. To better understand the progression of PD and improve treatment management, defining the disease on a structural basis and expanding brain analysis to extra-nigral structures is indispensable. The anatomical complexity and the presence of neuromelanin, make the use of non-human primates an essential element in developing putative imaging biomarkers of PD...

It is of paramount importance for consumers, scientists and industrialists to understand how low-temperature storage of food items affects their bioactive compounds and properties. This study evaluated the effects of cold storage on total phenolics (TP), phenolic acids profile (PA), total anthocyanins (TA), total ascorbic acid (Vit. C) and antioxidant activity (AA) of 19 fruits and vegetables, collected from local Indian markets and stored in refrigerator (4 °C) during 15 days. Content of TP was highest in dill and amaranth and decreased (up to 29...

BACKGROUND: This study seeks to quantify and compare bone marrow tolerance during postoperative chemotherapy therapy between rectal cancer vs. colon cancer patients. During rectal cancer treatment, patients receive neoadjuvant chemoradiation (CRT) irradiation which can exacerbate the hematologic toxicity (HT) via incidental irradiation of the pelvic bone marrow (PBM) during myelosuppressive postoperative chemotherapy. In contrast, colon cancer patients receive the same postoperative myelosuppressive chemotherapy but do not routinely receive preoperative chemoradiation therapy...

BACKGROUND: The aim was to assess whether cardiovascular adaptation to pregnancy in women with repaired tetralogy of Fallot (TOF) adversely affects hemodynamic stability, in particular with respect to right ventricular (RV) dilatation, pulmonary regurgitation, or aortic root dilatation. METHODS AND RESULTS: This was a retrospective cohort study of women with repaired TOF with paired cardiovascular magnetic resonance scans before and after their first pregnancy (baseline RV end systolic volume index 49 mL/m(2) and RV end diastolic volume index 118 mL/m(2)) matched with a comparison group of nulliparous women with TOF...

Multiple groups of patients have been recognized for having high rates of non-responders to the Hepatitis B vaccine including those with HIV, inflammatory bowel disease, and chronic kidney disease. These patients are at increased risk for infection due to both the nature of their underlying diseases and the immunosuppressive drugs they are commonly prescribed. Identification of groups with high non-response rates is essential in order to establish vaccination guidelines and prevent serious infections in already susceptible patients...

Infections with the Zika virus (ZIKV) are responsible for congenital abnormalities and neurological disorders. We here demonstrate that ZIKV productively infects three types of human iPSC (induced pluripotent stem cells)-derived cells from the neural lineage, i.e. cortical and motor neurons as well as astrocytes. ZIKV infection results in all three cell types in the production of infectious virus particles and induces cytopathic effects (CPE). In cortical and motor neurons, an Asian isolate (PRVABC59) produced roughly 10-fold more virus than the prototypic African strain (MR766 strain)...

BACKGROUND: Skin cancer is the most common malignancy after solid organ transplant and can lead to significant morbidity. The likelihood of developing squamous cell carcinomas and melanomas is 100 and 2.4 times more likely, respectively, in kidney transplant recipients when compared with the general population. There are few data regarding the assessment and influence of solid organ transplant recipient (SOTR) knowledge of skin cancer and its effect on short- and long-term awareness and behavior...

Despite major advances, ischemic cardiomyopathy (ICM) remains a significant cause of death and disability worldwide, with coronary artery disease (CAD) the leading cause of left ventricular (LV) systolic dysfunction. Coronary revascularization may improve LV function, heart failure symptoms and cardiovascular outcomes in high-risk patients with myocardial viability. Multiple imaging modalities have been utilized to detect viable myocardium and predict functional recovery following revascularization. Dobutamine stress echocardiography (DSE), nuclear imaging and cardiac MRI (CMR) are frequently used to assess viability...

We assessed the usability of consultation order templates and identified problems to prioritize in design efforts for improving referral communication. With a sample of 26 consultation order templates, three evaluators performed a usability heuristic evaluation. The evaluation used 14 domain-independent heuristics and the following three supplemental references: 1 new domain-specific heuristic, 6 usability goals, and coded clinicians' statements regarding ease of use for 10 sampled templates. Evaluators found 201 violations, a mean of 7...

Estrogen-related receptor α (ERRα) is an orphan nuclear receptor that has been functionally implicated in the regulation of energy homeostasis. Herein is described the development of indazole-based N-alkylthiazolidenediones, which function in biochemical assays as selective inverse agonists against this receptor. Series optimization provided several potent analogues that inhibited the recruitment of a co-activator peptide fragment in vitro (IC50s < 50 nM) and reduced fasted circulating insulin and triglyceride levels in a sub-chronic pre-diabetic rat model when administered orally (10 mg/kg)...

Wnt signaling is an important pathway that regulates several aspects of embryogenesis, stem cell maintenance, and neural connectivity. We have recently determined that opioids decrease Wnt secretion, presumably by inhibiting the recycling of the Wnt trafficking protein Wntless (Wls). This effect appears to be mediated by protein-protein interaction between Wls and the mu-opioid receptor (MOR), the primary cellular target of opioid drugs. The goal of this study was to identify novel protein interactors of Wls that are expressed in the brain and may also play a role in reward or addiction...

PURPOSE: Dosimetric studies have suggested greater cardiopulmonary sparing with protons over photons for left-sided postmastectomy radiation therapy (PMRT). Modern techniques such as deep inspiration breath hold (DIBH) can help spare the heart. This analysis compares photon and proton delivery with and without DIBH. METHODS AND MATERIALS: Ten women with left breast cancer referred for PMRT on a prospective clinical trial with unfavorable cardiac anatomy underwent free breathing (FB) and DIBH computed tomography simulation...

REVIEW
Shetal A Patel, Angela DeMichele
PURPOSE OF REVIEW: Residual disease after neoadjuvant chemotherapy is a poor prognostic factor; however, proven strategies to reduce recurrence risk and improve overall survival in this patient population are limited. Previous studies of residual disease have illustrated the importance of tumor intrinsic subtypes in treatment response and mechanisms of resistance. This review summarizes the rationale for various therapeutic approaches as well as completed and ongoing clinical trials for this high-risk group of patients...

Predictive and tempo-flexible synchronization to an auditory beat is a fundamental component of human music. To date, only certain vocal learning species show this behaviour spontaneously. Prior research training macaques (vocal non-learners) to tap to an auditory or visual metronome found their movements to be largely reactive, not predictive. Does this reflect the lack of capacity for predictive synchronization in monkeys, or lack of motivation to exhibit this behaviour? To discriminate these possibilities, we trained monkeys to make synchronized eye movements to a visual metronome...
