The prevalence of overweight and obesity in children and adolescents represents an emerging public health problem in Peru, so it is necessary to be aware of the different risk factors in order to establish suitable and efficient prevention measures. These should contribute to health strategies such as promoting physical activity and a healthy diet to ensure that the infant population reaches adulthood without chronic diseases and with an adequate quality of life.

REVIEW
John Withers, Xinnian Dong
Plants have evolved multi-layered molecular defense strategies to protect against pathogens. Plant immune signaling largely relies on post-translational modifications (PTMs) to induce rapid alterations of signaling pathways to achieve a response that is appropriate to the type of pathogen and infection pressure. In host cells, dynamic PTMs have emerged as powerful regulatory mechanisms that cells use to adjust their immune response. PTM is also a virulence strategy used by pathogens to subvert host immunity through the activities of effector proteins secreted into the host cell...

Volatile organic compounds (VOCs) severely threaten human health and the ecological environment because most of them are toxic, mutagenic, and carcinogenic. The persistent increase of VOCs together with the stringent regulations make the reduction of VOC emissions more imperative. Up to now, numerous VOC treatment technologies have emerged, such as incineration, condensation, biological degradation, absorption, adsorption, and catalysis oxidation et al. Among them, the adsorption technology has been recognized as an efficient and economical control strategy because it has the potential to recover and reuse both adsorbent and adsorbate...

This paper proposes a regional competitive governance and management of response and recovery from disasters. It presents problems experienced in major disasters, analyzes the failures, and suggests how a competitive system that relies on private and volunteer regional leaders, personnel, and capital can improve preparation, response and recovery efforts over the existing government system. A Public Choice approach is adopted to explain why government often fails, and how regional governance may be socially more efficient than the existing federal- state-local funded and managed disaster system...

Trifluoromethylselenylated compounds are emergent compounds with interesting physicochemical properties that still suffer from a lack of efficient synthetic methods. We recently developed an efficient one-pot strategy to generate in situ CF₃SeCl and use it in various reactions. Herein, we continue our study of the reactivity scope of this preformed reagent. Cross-coupling reactions with aromatic and heteroaromatic boronic acids have been investigated. The expected products have been obtained, using a stoichiometric amount of copper, with moderate yields...

Breast cancer is the leading cause of cancer related deaths in women and one of the most common cancers globally. The major obstacle in the management of breast cancer, especially at advanced stages, is metastasis. Metastasis in the advanced stages of breast cancer could decrease survival to approximately 5 years. The reasons could include lack of targeted receptors or chemotherapeutic agents for the management of advanced-stage breast cancer metastasis. The new emerging avenues for the management of this deadly pathological state include local manipulations like radiofrequency ablation (RFA), microwave thermotherapy, cryosurgery (cryotherapy), chemoembolization, radioembolization, breast surgery, or metastasectomy...

Synthetic polymer chemistry is a fundamental part of polymer science, and highly efficient polymerization reactions are essential for the synthesis of high-performance polymers. Development of new synthetic methods for emerging polymer science is of great importance in this regard. Bergman cyclization is a chemical process in which highly reactive aryl diradicals form from enediyne precursors, having a strong impact in a number of fields including pharmaceutics, synthetic chemistry, and materials science. Diradical intermediates stemming from enediynes can cause DNA cleavage under physiological conditions, leading to the strong cytotoxicity of many naturally occurring enediyne antibiotics...

Familial hypercholesterolemia (FH) is the most common inherited form of dyslipidemia and a major cause of premature cardiovascular disease. Management of FH mainly relies on the efficiency of treatments that reduce plasma low-density lipoprotein (LDL) cholesterol (LDL-C) concentrations. MicroRNAs (miRs) have been suggested as emerging regulators of plasma LDL-C concentrations. Notably, there is evidence showing that miRs can regulate the post-transcriptional expression of genes involved in the pathogenesis of FH, including LDLR, APOB, PCSK9, and LDLRAP1...

The inflammatory bowel diseases (IBD) are chronic incurable inflammatory disorders of the gut. Some 10% run a downhill course, requiring emergency medical support and often surgery; another small subset are monogenic, and, threatening pediatric patients, are the challenge of these days. The majority of the IBDs, however, are polygenic low-penetrance diseases, running a lifetime waxing-and-waning course. The prevalent trend is towards a slow worsening and steady cost increase. Each and all drugs of the available arsenal exhibit strengths and weaknesses: Mesalamines are chiefly effectively for mild-moderate colitis, and do not work in Crohn's; steroids do not control some 40% of the ulcerative colitis cases, and are not indicated for Crohn's; thiopurines are effective in the maintenance of the IBDs but do not prevent relapses on withdrawal; biologics are still being used empirically (not monitored) causing further increase of their cost over that of hospitalization...

Biocatalysts are creating increased interest among researchers due to their unique properties. Several enzymes are efficiently produced by microorganisms. However, the use of natural enzymes as biocatalysts is hindered by low catalytic efficiency and stability during various industrial processes. Many advanced enzyme technologies have been developed to reshape the existing natural enzymes to reduce these limitations and prospecting of novel enzymes. Frequently used enzyme technologies include protein engineering by directed evolution, immobilisation techniques, metagenomics etc...

Metal-organic frameworks (MOFs) have been emerged as promising stationary phases for separations. However, the irregular shapes and wide size distribution of MOF particles have led to the high column backpressure and low column efficiency. We described here a kinetic controlling method to deposit zeolitic imidazolate framework (ZIF-8) onto the pore surface using core-shell silica spheres as support. By varying the volume ratio of N,N-dimethylformamide and methanol, the formation speed of ZIF-8 crystals were greatly suppressed, resulting in the growth of very thin layer (∼3...

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60 years old. The literature search produced 271 records for physical performance (n = 119), frailty (n = 31), and mortality (n = 121)...

Protein synthesis is the outcome of tightly regulated gene expression which is responsive to a variety of conditions. Efforts are ongoing to monitor individual stages of protein synthesis to ensure maximum efficiency and accuracy. Due to post-transcriptional regulation mechanisms, the correlation between translatome and proteome is higher than between transcriptome and proteome. However, the most accurate approach to assess the key modulators and final protein expression is directly by using proteomics. Areas covered: This review covers various proteomic strategies that were used to better understand post-transcriptional regulation, specifically during and early after translation...

Islets from xeno-sources and islet like clusters derived from autologus stem cells have emerged as alternatives to cadaveric pancreas used for treatment of type 1 diabetes. However, the immuno-isolation of these islets from the host immune system suffers from the issue of biocompatibility and hypoxia. To overcome the issues of immunobarrier biocompatibility, we developed a Polysulfone (Psf)/TPGS composite hollow fiber membrane (HFM) using a hollow fiber spinning pilot plant specially developed for this purpose...

The differentiation of induced pluripotent stem cells (iPSCs) in biomaterial scaffolds is an emerging area for biomedical applications. This study proposes, for the first time, the production of pancreatic cells from iPSCs in gelatin-poly(lactide-co-glycolide) nanoparticle (PLGA NP) scaffolds. The porosity and swelling ratio of the scaffolds decreased with increases in gelatin and PLGA NP concentrations. The adhesion efficiency of iPSCs in gelatin-PLGA NP scaffolds was found to be higher at 6.7% (w/w) PLGA NP...

Damnacanthal (Dam) is a phytochemical with many pharmacological properties including anticancer activity. However, its hydrophobicity, poor bioavailability and stability limit its application in many biological approaches. In this study, Dam nanomicelles as an emerging platform were developed to overcome limitations. The deoxycholic and poly(ethylene glycol) methyl ether grafted chitosan (DCA-CS-mPEG) was synthesized and characterized by FTIR and (1)H NMR and the degree of substitution (DS) was determined by elemental analysis (EA)...

This study provided the first comprehensive data on the occurrence and removal of twenty-five target emerging contaminants (ECs) in a full-scale water reclamation plant (WRP) in the Southeast Asian region. Nineteen out of the twenty-five ECs were ubiquitously detected in raw influent samples. Concentrations of the detected ECs in raw influent samples ranged substantially from 44.3 to 124,966ng/L, depending upon the compound and sampling date. The elimination of ECs in full-scale conventional activated sludge (CAS) and membrane bioreactor (MBR) systems at a local WRP was evaluated and compared...

Metabolomics uses advanced analytical chemistry techniques to comprehensively measure large numbers of small molecule metabolites in cells, tissues and biofluids. The ability to rapidly detect and quantify hundreds or even thousands of metabolites within a single sample is helping scientists paint a far more complete picture of system-wide metabolism and biology. Metabolomics is also allowing researchers to focus on measuring the end-products of complex, hard-to-decipher genetic, epigenetic and environmental interactions...

Little is known about the pattern of genetic testing and frequency of genetic diagnoses among children enrolled in structured complex care programs (CCPs). Such information may inform the suitability of emerging genome diagnostics for this population. The objectives were to describe the proportion of children with undiagnosed genetic conditions despite genetic testing and measure the testing period, types and costs of genetic tests used. A retrospective analysis of 420 children enrolled in Toronto's Hospital for Sick Children's CCP from January 2010 until June 2014 was conducted...
