BACKGROUND: The role of insulin resistance (IR) in the pathogenesis of cognitive performance is not yet clear. OBJECTIVE: To examine the associations between IR and cognitive performance and change in cognitive functions two decades later in individuals with cardiovascular disease with and without diabetes. METHODS: A subset of 489 surviving patients (mean age at baseline 58±6.6 y) with coronary heart disease who previously participated in the secondary prevention Bezafibrate Infarction Prevention (BIP trial; 1990-1997), were included in the current neurocognitive study...

BACKGROUND: The relationship of obesity with risk for dementia is complex and may change with age. OBJECTIVE: To analyze the relationship between measures of obesity at age 40-65 and dementia prevalence in survivors 36 years later. METHODS: Obesity-related measures of triceps and subscapular skinfold thickness were assessed in 1963 in n = 9,760 men aged 40-65 participating in the Israel Ischemic Heart Disease study. Cognitive evaluation and assessment of dementia prevalence were performed in n = 1,643 participants of the original cohort who survived until 1999/2000 (age ≥76 years) and had anthropometric measures in 1963...

BACKGROUND: Because of the rarity of this condition, information on pregnancy-associated spontaneous coronary artery dissection is limited. We reviewed a large number of contemporary pregnancy-associated spontaneous coronary artery dissection cases in an attempt to define the clinical characteristics and provide management recommendations. METHODS AND RESULTS: A literature search for cases of pregnancy-associated spontaneous coronary artery dissection reported between 2000 and 2015 included 120 cases; 75% presented with ST-segment-elevation myocardial infarction, and 80% had anterior myocardial infarction...

Food entrainment is the internal mechanism whereby the phase and period of circadian clock genes comes under the control of daily scheduled food availability. Food entrainment allows the body to efficiently realign the internal timing of behavioral and physiological functions such that they anticipate food intake. Food entrainment can occur with or without caloric restriction, as seen with daily schedules of restricted feeding (RF) or restricted treat (RT) that restrict food or treat intake to a single feeding time...

BACKGROUND: Antibiotic overuse causes antibiotic resistance, one of the most important threats to human health. Older adults, particularly those in nursing homes, often receive antibiotics when they are not indicated. METHODS: To understand knowledge, attitudes, and behaviors of nursing home (NH) nurses and community-dwelling older adults towards antibiotic use, especially in clinical situations consistent with antibiotic overuse, we conducted a mixed-method survey in two NHs and one Family Medicine clinic in North Carolina, among English-speaking nurses and community-dwelling, cognitively intact adults aged 65 years or older...

BACKGROUND: The importance of mobility impairments in people with multiple sclerosis (PwMS) denotes a need for valid, reliable, sensitive and feasible clinical measuring tools. The Timed Up and Go (TUG) test is a unique mobility measure as it captures other functions apart from walking, ie, rising out of a chair or turning around an object. AIM: To expand the construct validity of the TUG test in PwMS and determine the ability of the TUG score to discriminate between four levels of disability between fallers, recurrent fallers and non-fallers...

REVIEW
Uri Galili
Significance: Rapid recruitment and activation of macrophages may accelerate wound healing. Such accelerated healing was observed in wounds and burns of experimental animals treated with α-gal nanoparticles. Recent Advances: α-Gal nanoparticles present multiple α-gal epitopes (Galα1-3Galβ1-4GlcNAc-R). α-Gal nanoparticles applied to wounds bind anti-Gal (the most abundant antibody in humans) and generate chemotactic complement peptides, which rapidly recruit macrophages. Fc/Fc receptor interaction between anti-Gal coating the α-gal nanoparticles and recruited macrophages activates macrophages to produce cytokines that accelerate healing...

Analysis of coupled variables is a core concept of cell biological inference, with co-localization of two molecules as a proxy for protein interaction being a ubiquitous example. However, external effectors may influence the observed co-localization independently from the local interaction of two proteins. Such global bias, although biologically meaningful, is often neglected when interpreting co-localization. Here, we describe DeBias, a computational method to quantify and decouple global bias from local interactions between variables by modeling the observed co-localization as the cumulative contribution of a global and a local component...

Heparan sulfate (HS) mediates the activity of various growth factors including TGF-β. Heparanase is an endo-glucuronidase that specifically cleaves and modifies HS structure. In this study, we examined the effect of heparanase expression on TGF-β1-dependent signaling activities. We found that overexpression of heparanase in human tumor cells (i.e., Fadu pharyngeal carcinoma, MCF7 breast carcinoma) attenuated TGF-β1-stimulated Smad phosphorylation and led to a slower cell proliferation. TGF-β1-stimulated Akt and Erk phosphorylation was also affected in the heparanase overexpression cells...

PURPOSE: Sterilization via bilateral total salpingectomy is slowly replacing partial salpingectomy, as it is believed to decrease the incidence of ovarian cancer. Our objective was to compare short-term intra and post-operative complication rates of bilateral total salpingectomy versus partial salpingectomy performed during the course of a cesarean delivery. METHODS: A large series of tubal sterilizations during cesarean sections were studied in a single tertiary medical center between 1/2014 and 8/2016 before and after a policy change was made, switching from partial salpingectomy to total salpingectomy...

Lital Davidi, Uri Pick
We identified and demonstrated the function of 9-cis/all-trans β-carotene isomerases in plastidic globules of Dunaliella bardawil, the species accumulating the highest levels of 9-cis β-carotene that is essential for humans. The halotolerant alga Dunaliella bardawil is unique in that it accumulates under light stress high levels of β-carotene in plastidic lipid globules. The pigment is composed of two major isomers: all-trans β-carotene, the common natural form of this pigment, and 9-cis β-carotene. The biosynthetic pathway of β-carotene is known, but it is not clear how the 9-cis isomer is formed...

Temporary abdominal closure (TAC) techniques are routinely used in the open abdomen. Ideally, they should prevent evisceration, aid in removal of unwanted fluid from the peritoneal cavity, facilitate in achieving safe definitive fascial closure, as well as prevent the development of intra-abdominal complications. TAC techniques used in the open abdomen were compared with negative pressure wound therapy (NPWT) to identify which was superior. A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines involving Medline, Excerpta Medica, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and <ext-link ext-link-type="uri" xlink:href="http://Clinicaltrials...

William E Cross
Urie Bronfenbrenner (1992) helped developmental psychologists comprehend and define "context" as a rich, thick multidimensional construct. His ecological systems theory consists of five layers, and within each layer are developmental processes unique to each layer. The four articles in this section limit the exploration of context to the three innermost systems: the individual plus micro- and macrolayers. Rather than examine both the physical features and processes, the articles tend to focus solely on processes associated with a niche...

We present new evidence for the existence of a large pockmark field on the continental slope of the Santos Basin, offshore southeast Brazil. A recent high-resolution multibeam bathymetric survey revealed 984 pockmarks across a smooth seabed at water depths of 300-700 m. Four patterns of pockmark arrays were identified in the data: linear, network, concentric, and radial. Interpretation of Two-dimensional multi-channel seismic reflection profiles that crosscut the surveyed area shows numerous salt diapirs in various stages of development (e...

Structurally diverse inhibitors of the protein kinase CK2 are required for regulation of this ubiquitous protein to establish biological roles of the enzyme which catalyzes the phosphorylation of a vast number of substrate proteins. In this article we disclose a series of new bisubstrate inhibitors of CK2 that are structurally represented by the oligo(l-Asp) peptide conjugates of benzo[c][2,6]naphthyridine-8-carboxylic acid. This fragment originated from CX-4945, the first in class inhibitor taken to clinical trials...

BACKGROUND: Drugs often kill some cancer cells while others survive. This stochastic outcome is seen even in clonal cells grown under the same conditions. Understanding the molecular reasons for this stochastic outcome is a current challenge, which requires studying the proteome at the single cell level over time. In a previous study we used dynamic proteomics to study the response of cancer cells to a DNA damaging drug, camptothecin. Several proteins showed bimodal dynamics: they rose in some cells and decreased in others, in a way that correlated with eventual cell fate: death or survival...

This paper reviews the state-of-the-art in simulation-based studies of Tumor Treating Fields (TTFields) and highlights major aspects of TTFields in which simulation-based studies could affect clinical outcomes. A major challenge is how to simulate multiple scenarios rapidly for TTFields delivery. Overcoming this challenge will enable a better understanding of how TTFields distribution is correlated with disease progression, leading to better transducer array designs and field optimization procedures, ultimately improving patient outcomes...

Tumor Treating Fields (TTFields) are low intensity alternating electric fields in the 100-500 KHz frequency range that are known to have an anti-mitotic effect on cancerous cells. In the USA, TTFields are approved by the Food and Drug Administration (FDA) for the treatment of glioblastoma (GBM) in both the newly diagnosed and recurrent settings. Optimizing treatment with TTFields requires a deep understanding of how TTFields distribute within the brain. To address this issue, simulations using realistic head models have been performed...
