In the diagnosis of various cancers by analyzing histological images, automatic nuclear segmentation is an important step. However, nuclear segmentation is a difficult problem because of overlapping nuclei, inhomogeneous staining, and presence of noisy pixels and other tissue components. In this paper, we present an automatic technique for nuclear segmentation in skin histological images. The proposed technique first applies a bank of generalized Laplacian of Gaussian (gLoG) kernels to detect nuclear seeds...

Polypharmacy is growing in Canada, along with adverse drug events and drug-related costs. Part of the solution may be deprescribing, the planned and supervised process of dose reduction or stopping of medications that may be causing harm or are no longer providing benefit. Deprescribing can be a complex process, involving the intersection of patients, health care providers, and organizational and policy factors serving as enablers or barriers. This article describes the justification, theoretical foundation, and process for developing a Canadian Deprescribing Network (CaDeN), a network of individuals, organizations, and decision-makers committed to promoting the appropriate use of medications and non-pharmacological approaches to care, especially among older people in Canada...

Intake of sugary beverages is strongly associated with weight gain and obesity among children; however, differences between mothers' and grandmothers' attitudes and practices concerning young children's beverage consumption remain unclear. This is notable since about a quarter of families in the US and the UK rely on grandparents as the main providers of informal childcare. The aim of this study is to examine mothers' and maternal grandmothers' attitudes, knowledge, and practices regarding preschool-age children's beverage consumption...

REVIEW
Waqar Arif, Gandhar Datar, Auinash Kalsotra
Intermediary metabolism studies have typically concentrated on four major regulatory mechanisms-substrate availability, allosteric enzyme regulation, post-translational enzyme modification, and regulated enzyme synthesis. Although transcriptional control has been a big focus, it is becoming increasingly evident that many post-transcriptional events are deeply embedded within the core regulatory circuits of enzyme synthesis/breakdown that maintain metabolic homeostasis. The prominent post-transcriptional mechanisms affecting intermediary metabolism include alternative pre-mRNA processing, mRNA stability and translation control, and the more recently discovered regulation by noncoding RNAs...

Mutsumi Nagai, Mami Ishikawa
OBJECTIVE: During a decompressive craniectomy performed for a severe cerebral infarction, sufficient coverage of the underlying bulging brain by converting the flat dura mater to a more dome-like shape is essential. In this procedure, suturing to patch dural substitutes on the dural rifts occupies most of the operative time and is cumbersome. We present a new dural incision design that provides an appropriate volume of subdural space with minimal incisions. METHODS: The ideal incision design was geometrically analyzed and verified by simulations using a physics engine...

BACKGROUND: Diffusion Tensor Magnetic Resonance Imaging (DT-MRI, also known as DTI) measures the diffusion properties of water molecules in tissues and to date is one of the main techniques that can effectively study the microstructures of the brain in vivo. Presently, evaluation of DTI registration techniques is still in an initial stage of development. METHODS AND RESULTS: In this paper, six well-known open source DTI registration algorithms: Elastic, Rigid, Affine, DTI-TK, FSL and SyN were applied on 11 subjects from an open-access dataset, among which one was randomly chosen as the template...

HIV testing is a 'gateway' technology, enabling access to treatment and HIV prevention. Biomedical approaches to prevention, such as pre-exposure prophylaxis and treatment as prevention, require accurate and regular HIV test results. HIV testing also represents a powerful 'teachable moment' for behavioural prevention. An increasing range of HIV tests and the emergence of self-managed diagnostic technologies (e.g. self-testing) means there is now considerable diversification of when, where and how results are available to those who test...

REVIEW
Cameron S Osborne, Borbála Mifsud
There is a strong interrelationship within the cell nucleus between form and function of the genome. This connection is exhibited across multiple hierarchies, ranging from grand-scale positioning of chromosomes and their intersection with specific nuclear functional activities, the segregation of chromosome structure into distinct domains and long-range regulatory contacts that drive spatial and temporal expression patterns of genes. Fifteen years ago, the development of the chromosome conformation capture method placed the nature of specific, long-range regulatory interactions under scrutiny...

Cannabis use among older Americans is increasing. Although much of this growth has been attributed to the entry of a more tolerant baby boom cohort into older age, recent evidence suggests the pathways to cannabis are more complex. Some older persons have responded to changing social and legal environments and are increasingly likely to take cannabis recreationally. Other older persons are experiencing age-related health care needs, and some take cannabis for symptom management, as recommended by a medical doctor...

OBJECTIVE: We conceptualize successful aging as a cumulative index of individual resources (the absence of disease and disability, high cognitive and physical functioning, social embeddedness) in the service of successful aging outcomes (global well-being, experienced well-being, and vital status), and conditioned by age, social structure, and environment. METHOD: The study used baseline and follow-up data from the 2008-2014 waves of the Health and Retirement Study (N = 17,230; age = 51-101)...

Using coarse-grained dissipative particle dynamics (DPD) simulations, we systematically study the effect of surface heterogeneity on surfactant adsorption. Here we investigate the adsorption and aggregation of surfactants on hydrophobic stripes crossing each other perpendicularly (i.e., crossing stripes) and on hydrophobic steps. The results are compared with those obtained for isolated stripes. We find that on crossing stripes of moderate stripe widths (e.g., L = 0.61LS, 1.22LS and 1.83LS, where LS is the length of one surfactant molecule) the crossing region hinders the formation of defect-free adsorbed surfactant structures...

Violence has become a characteristic feature of South African society, with women and children often bearing the brunt of this. Contemporary research suggests that the key to stemming the tide of child victimisation is understanding the complete inventory of victimisations that may co-occur during childhood. There is growing recognition that children in South Africa typically experience abuse in the context of other forms of maltreatment and victimisation. This article draws on the empirical data collected for a national prevalence and incidence study on child sexual abuse and maltreatment in South Africa and draws attention to the frequency of poly-victimisation amongst South African children and highlights why some children experience multiple co-occurring forms of victimisations while others do not...

Substituent and solvent effects on the excited state dynamics of the Photoactive Yellow Protein chromophore are studied using the average solvent electrostatic potential from molecular dynamics (ASEP/MD) method. Four molecular models were considered: the ester and thioester derivatives of the p-coumaric acid anion and their methyla ted derivatives. We found that the solvent produces dramatic modifications on the free energy profile of the S1 state: 1) Two twisted structures that are minima in gas phase could not be located in aqueous solution...

Mechanical subacromial rotator cuff compression is one theoretical mechanism in the pathogenesis of rotator cuff disease. However, the relationship between shoulder kinematics and mechanical subacromial rotator cuff compression across the range of humeral elevation motion is not well understood. The purpose of this study was to investigate the effect of humeral elevation on subacromial compression risk of the supraspinatus during a simulated functional reaching task. Three-dimensional anatomical models were reconstructed from shoulder magnetic resonance images acquired from 20 subjects (10 asymptomatic, 10 symptomatic)...

REVIEW
Marcia Elizabeth Sutherland
Caribbean youth comprise about 30 percent of the English-speaking Caribbean population, and about 81,000 Caribbean and Latin American youth are HIV infected. AIDS is the leading cause of death for 15- to 24-year-old English-speaking Caribbean youth. This article relies on intersectionality theory in the assessment of the macro-level, or structural variables, and micro-level, or individual level, variables that influence the risk-taking sexual behaviors of heterosexual English-speaking Caribbean youth and increase their vulnerability to HIV/sexually transmitted infections...

To address the limitation of the existing UAV (unmanned aerial vehicles) photoelectric localization method used for moving objects, this paper proposes an improved two-UAV intersection localization system based on airborne optoelectronic platforms by using the crossed-angle localization method of photoelectric theodolites for reference. This paper introduces the makeup and operating principle of intersection localization system, creates auxiliary coordinate systems, transforms the LOS (line of sight, from the UAV to the target) vectors into homogeneous coordinates, and establishes a two-UAV intersection localization model...

Inappropriate activation of apoptosis may contribute to neurodegeneration, a multifaceted process that results in various chronic disorders, including Alzheimer's and Parkinson's diseases. Several in vitro and in vivo studies demonstrated that neuronal apoptosis is a multi-pathway cell-death program that requires RNA synthesis. Thus, transcriptionally activated genes whose products induce cell death can be triggered by different stimuli and antagonized by neurotrophic factors. Systems biology is now unveiling the series of intracellular signaling pathways and key drug targets at the intersection of neuronal apoptosis and survival...

Most neuronal populations form on both the left and right sides of the brain. Their efferent axons appear to grow synchronously along similar pathways on each side, although the neurons or their environment often differ between the two hemispheres [1-4]. How this coordination is controlled has received little attention. Frequently, neurons establish interhemispheric connections, which can function to integrate information between brain hemispheres (e.g., [5]). Such commissures form very early, suggesting their potential developmental role in coordinating ipsilateral axon navigation during embryonic development [4]...
