In modern agriculture, with more emphasis on high input systems, weed problems are likely to increase and become more complex. With heightened awareness of adverse effects of herbicide residues on human health and environment and the evolution of herbicide-resistant weed biotypes, a significant focus within weed science has now shifted to the development of eco-friendly technologies with reduced reliance on herbicides. Further, with the large-scale adoption of herbicide-resistant crops, and uncertain climatic optima under climate change, the problems for weed science have become multi-faceted...

The Ziziphus species are considered to be the medicine and food dual purposes plants. Among them, the seed of Ziziphus jujuba var. spinosa (ZS) has traditionally been used as an ethnomedicine in Asian countries for thousands years. Owing to the significant benefits for human health, the demand for ZS increased year by year, and the wild resources have become increasingly scarce, which resulted in a shortage of market supply for ZS and product adulteration by substituting ZS with the seeds of Z. mauritiana Lam...

The characterization of elemental cycles has a rich history in biogeochemistry. Well known examples include the global carbon cycle, or the cycles of the 'grand nutrients' nitrogen, phosphorus, and sulfur. More recently, efforts have increased to better understand the natural cycling of technology critical elements (TCEs), i.e. elements with a high supply risk and economic importance in the EU. On the other hand, tools such as material-flow analysis (MFA) can help to understand how substances and goods are transported and accumulated in man-made technological systems ('anthroposphere')...

Endophytic actinobacteria play an important role in growth promotion and development of host plant by producing enormous quantities of novel bioactive natural products. In the present investigation, 169 endophytic actinobacteria were isolated from endospheric tissues of Rhynchotoechum ellipticum. Based on their antimicrobial potential, 81 strains were identified by 16rRNA gene analysis, which were taxonomically grouped into 15 genera. All identified strains were screened for their plant growth promoting attributes and, for the presence of modular polyketide synthases (PKSI, PKSII and nonribosomal peptide synthetase (NRPS) gene clusters to correlate the biosynthetic genes with their functional properties...

Paul E Pfeffer, Catherine M Hawrylowicz
There is increasing interest in the therapeutic utility of vitamin D in asthma, supported by a significant body of evidence on epidemiological associations between vitamin D insufficiency and worse asthma control. In support of a causal relationship, vitamin D beneficially modulates diverse immunological pathways in heterogeneous asthma endotypes, regulating the actions of lymphocytes, mast cells, antigen-presenting cells and structural cells to dampen excessive inflammatory responses. Allergic asthma is characterised by a failure of immune tolerance, and development of pathological responses to inhaled aeroallergens, and vitamin D has been extensively shown to support immune regulation...

PURPOSE OF REVIEW: For many diseases that place a large burden on our health care system, men often have worse health outcomes than women. As the largest single provider of health care to men in the USA, the Veterans Health Administration (VA) has the potential to serve as leader in the delivery of improved men's health care to address these disparities. RECENT FINDINGS: The VA system has made recent strides in improving benefits for aspects of men's health that are traditionally poorly covered, such as treatment for male factor infertility...

REVIEW

There is great interest lately, in the use of herbs for the treatment of hypertension and cardiovascular disease (CVD). Herbs and plants contain many phytochemicals that have been effective in the treatment of CVD and hypertension. Accumulating scientific evidence provides a reason for the use of herbs by health practitioners for treating their patients. The rationale for this expanding use of herbs is the belief of patients in a "holistic medicine" and that herbs are natural, safe, and effective. However, there are reasons of concern with the use of herbs, because they are not regulated or supervised carefully and their use could lead to serious complications or interactions with their combination with traditional medicines...

We describe an automated methodology for the analysis of unregistered cranio-caudal (CC) and medio-lateral oblique (MLO) mammography views in order to estimate the patient's risk of developing breast cancer. The main innovation behind this methodology lies in the use of deep learning models for the problem of jointly classifying unregistered mammogram views and respective segmentation maps of breast lesions (i.e., masses and micro-calcifications). This is a holistic methodology that can classify a whole mammographic exam, containing the CC and MLO views and the segmentation maps, as opposed to the classification of individual lesions, which is the dominant approach in the field...

Oxidation generates multiple diverse post-translational modifications resulting in changes in protein structure and function, associated with a wide range of diseases. Of these modifications, carbonylations have often been used as hallmarks of oxidative damage. However, accumulating evidence supports the hypothesis that other oxidation products may be quantitatively more important under physiological conditions. To address this issue we have developed a holistic mass spectrometry-based approach for simultaneous identification, localization and quantification of a broad range of oxidative modifications based on so-called 'dependent peptides'...

Insufficiency fracture care requires more than surgery to ensure rapid and strong union with diminished chance of future fractures. The FLS program provides an opportunity to treat osteoporosis from a public health perspective rather than leaving this to the whims of individual physicians. This is achieved by providing a seamless integration of care by health care providers, nursing staff and administration. The FLS can be adapted to any model of care including academic health systems. FLS provides a holistic approach to identify patients as well as to provide evidence-based interventions to prevent subsequent fractures...

REVIEW
Toshiyuki Nakajima
Evolution by natural selection requires the following conditions: (1) a particular selective environment, (2) variation of traits in the population; (3) differential survival/reproduction among types of organisms; and (4) heritable traits. However, the traditional (standard) model does not unclearly explain how and why these conditions are generated or determined. What generates a selective environment? What generates new types? How does a certain type replace, or coexist, with others? In this paper, based on the holistic philosophy in Western and Eastern traditions, I focus on the ecosystem as a higher-level system and generator of conditions that induce the evolution of local populations; I also aim to identify the ecosystem processes that generate those conditions...

The p53 protein is a sophisticated transcription factor that regulates dozens of target genes simultaneously in accordance with the cellular circumstances. Although considerable efforts have been made to elucidate the functions of p53-induced genes, a holistic understanding of the orchestrated signaling network repressed by p53 remains elusive. Here, we performed a systematic analysis to identify simultaneously regulated p53-repressed genes in breast cancer cells. Consequently, 28 genes were designated as the p53-repressed gene module, whose gene components were simultaneously suppressed in breast cancer cells treated with Adriamycin...

Pasifika Support Services (PSS) was a program managed by a nongovernment organization, Mission Australia, and funded by the New South Wales Premiers Office to meet the needs of young offenders from a Pacific background. PSS ran from June 2005 to June 2009 and implemented a cost-effective integrated case management model with the New South Wales Police Force adapted to address social risk factors specific to Pacific youth offenders and family support networks. Sixty young people were reviewed regarding the outcomes achieved through their participation, further supported by an evaluation carried out by an external evaluator who found that 65% of participants did not reoffend after 18 months of completing the program...

BACKGROUND: Exclusion from school is increasingly recognized as pertinent to child health. National educational data reveal that boys, children who are looked-after, living in poverty, have special educational needs, or from certain ethnic minorities, are disproportionately excluded from school. As population-based data on the wider characteristics of excluded children are scarce, we aimed to describe predictors of school exclusion in the Avon Longitudinal Study of Parents and Children...
