Head and neck cancer remains a significant public health concern. About 60% of patients die within 5years due to local recurrence. Head and neck squamous cell carcinoma (HNSCC) cell lines are important preclinical models in the search for new therapies against this disease. Furthermore, there is a need to test novel drugs before introduction into clinical practice. A preclinical model that closely resembles the in vivo situation would be highly valuable. In the last few decades, a multicellular spheroid model has gained attention as its behavior was comparable to in vivo tumors...

Systemic treatments are tailored to breast cancer (BC) heterogeneity, which is not yet taken into account for radiotherapy (RT) personalization. The primary objective of this review is to summarize existing data suggesting BC subtypes and genetic assays are prognostic and predictive biomarkers useful for RT decision-making and to provide implications for their incorporation into future translational and clinical research. The evidence suggesting that BC subtypes also exhibit distinct "locoregional recurrence (LRR)" patterns is retrospective but consistent and validated in over fifteen studies...

: National guidelines for smoking cessation in primary care can be effective in improving clinical practice. This study assessed which parties are involved in the development of such guidelines worldwide, which national guidelines address primary care, what recommendations are made for primary care settings, and how these recommendations correlate with each other and with current evidence. We identified national guidelines using an online resource. Only the most recent version of a guideline was included...

BACKGROUND: National sporting achievement at the Olympic Games is important for national pride and prestige, and to promote participation in sport. Summer Olympic Games medal tallies have been associated with national wealth, and also social development and healthcare expenditure. It is uncertain however, how these socioeconomic factors translate into Olympic success. The objective of this study was therefore to examine the relationship between population muscle strength and Olympic medal tallies...

BACKGROUND: Guatemala exhibits the sixth highest rate of child stunting worldwide, and stunting disproportionately affects Guatemala indigenous communities. In a country struggling to combat this result of malnutrition, early child nutrition is especially critical. Specifically, early initiation of breastfeeding is important for the development of newborn infants. Understanding beliefs and practices related to early initiation of breastfeeding in Maya Guatemala may provide an avenue to guide nutrition interventions in indigenous communities...

Hepatobiliary and pancreatic (HBP) cancers are associated with high cancer-related death rates. Surgery aiming for complete tumor resection (R0) remains the cornerstone of the treatment for HBP cancers. The current progress in the adjuvant treatment is quite slow, with gemcitabine chemotherapy available only for pancreatic ductal adenocarcinoma (PDA). In the advanced and metastatic setting, only two targeted drugs have been approved by the Food & Drug Administration (FDA), which are sorafenib for hepatocellular carcinoma and erlotinib for PDA...

Precision medicine is based on a simple precept that deep information about an individual patient can be used to guide his or her health care. In the not-too-distant future, clinicians may have point-of-care access to an individual's entire genome, dense data captured from wearable devices, and informatics tools that aggregate data from clinical experience to allow for real-time decision support. The innovative technologies being developed in pursuit of precision medicine afford researchers and clinicians the opportunity to generate and consume information at an unprecedented scale...

N(6)-methyladenosine (m(6)A) is the most abundant internal modification in eukaryotic messenger RNAs (mRNAs), and plays important roles in cell differentiation and tissue development. It regulates multiple steps throughout the RNA life cycle including RNA processing, translation, and decay, via the recognition by selective binding proteins. In the cytoplasm, m(6)A binding protein YTHDF1 facilitates translation of m(6)A-modified mRNAs, and YTHDF2 accelerates the decay of m(6)A-modified transcripts. The biological function of YTHDF3, another cytoplasmic m(6)A binder of the YTH (YT521-B homology) domain family, remains unknown...

Retinoid X receptors (RXRs) form a unique subclass within the nuclear receptor (NR) superfamily of ligand-dependent transcription factors. RXRs are obligatory partners for a number of other NRs, placing RXRs in a coordinating role at the crossroads of multiple signaling pathways. In addition, RXRs can function as self-sufficient homodimers. Recent advances have revealed RXRs as novel regulators of osteoclastogenesis and bone remodeling. This review outlines the versatility of RXR action in the control of transcription of bone-forming osteoblasts and bone-resorbing osteoclasts, both through heterodimerization with other NRs and through RXR homodimerization...

Proteomic plasticity undergirds stress responses in plants, and understanding such responses requires accurate measurement of the extent to which proteins levels are adjusted to counter external stimuli. Here, we adapt bioorthogonal non-canonical amino acid tagging (BONCAT) to interrogate protein synthesis in vegetative Arabidopsis thaliana seedlings. BONCAT relies on the translational incorporation of a non-canonical amino acid (ncAA) probe into cellular proteins. In this study, the probe is the methionine surrogate azidohomoalanine (Aha), which carries a reactive azide moiety in its amino acid side chain...

Although irritability is among the most common reasons that children and adolescents are brought for psychiatric care, there are few effective treatments. Developmentally sensitive pathophysiological models are needed to guide treatment development. In this review, the authors present a mechanistic model of irritability that integrates clinical and translational neuroscience research. Two complementary conceptualizations of pathological irritability are proposed: 1) aberrant emotional and behavioral responding to frustrative nonreward, mediated by reward-system dysfunction; and 2) aberrant approach responding to threat, mediated by threat-system dysfunction...

Activation and proliferation of resident cardiac progenitor cells has therapeutic potential to repair the heart after injury. However, research has been impeded by a lack of well-defined and characterized cell sources and difficulties in translation to screening platforms. Here, we describe the development, validation, and use of a 384-well phenotypic assay in primary human epicardium-derived cells (EPDCs) to identify compounds that induce proliferation while maintaining the progenitor phenotype. Using this assay, we screened 7400 structurally diverse compounds where greater than 90% are biologically annotated and known to modulate a broad range of biological targets...

Development of safe non-viral carrier systems for efficient intra-cellular delivery of drugs and genes hold promise in the area of translational research. Liposome based delivery systems have emerged as one of the attractive strategies for efficient delivery of drugs and nucleic acids. To this end, number of investigations was carried on liposomal formulations using lipids for achieving higher efficiency in transfection with lower cytotoxicities. In our efforts to develop safer and efficient liposomal delivery systems, we synthesized a novel anti-oxidant lipid, α-lipoyl, oleyl-sn-phosphatidylcholine (LOPC) and used as a helper lipid in combination with a cationic amphiphile, Di-Stearyl Dihydroxy Ethyl Ammonium Chloride (DSDEAC) and 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) at varying concentrations of LOPC...

REVIEW
Miranda S C Wilson, Adolfo Saiardi
Inositol polyphosphates, in their water-soluble or lipid-bound forms, represent a large and multifaceted family of signalling molecules. Some inositol polyphosphates are well recognised as defining important signal transduction pathways, as in the case of the calcium release factor Ins(1,4,5)P3, generated by receptor activation-induced hydrolysis of the lipid PtdIns(4,5)P2 by phospholipase C. The birth of inositol polyphosphate research would not have occurred without the use of radioactive phosphate tracers that enabled the discovery of the "PI response"...
