Considerable advances in oncology over recent decades have led to improved survival, while raising concerns about long-term consequences of anticancer treatments. In patients with breast or prostate malignancies, bone health is a major issue due to the high risk of bone metastases and the frequent prolonged use of hormone therapies that alter physiological bone turnover, leading to increased fracture risk. Thus, the onset of cancer treatment-induced bone loss (CTIBL) should be considered by clinicians and recent guidelines should be routinely applied to these patients...

Interest in research into bioactive peptides (BPs) is growing because of their health-promoting ability. Several bioactivities have been ascribed to peptides, including antioxidant, antihypertensive and antimicrobial properties. As they can be produced from precursor proteins, the investigation of BPs in foods is becoming increasingly popular. For the same reason, production of BPs from by-products has also emerged as a possible means of reducing waste and recovering value-added compounds suitable for functional food production and supplements...

Advances in proteomics have fueled the search for novel cancer biomarkers with higher selectivity. Differential expression of low abundant proteins has been the usual way of finding those biomarkers. The existence of a selective receptor for each biomarker is compulsory for their use in diagnostic/prognostic assays. Antibodies are the receptors of choice in most cases although aptamers are becoming familiar because of their facile and reproducible synthesis, chemical stability as well as comparable affinity and selectivity...

BACKGROUND: Fluoropyrimidine and platinum combination is the standard treatment for advanced or recurrent gastric cancer (AGC). However, fluoropyrimidine monotherapy is commonly used for elderly patients with AGC because of its good tolerability. METHODS: In this multicenter retrospective study, we collected clinical data of AGC patients aged 70 years or older, treated with S-1 alone or S-1 plus cisplatin (SP) as the first-line treatment between January 2009 and December 2011...

REVIEW
Aleksandar Ivetic
L-selectin is a type I transmembrane cell adhesion molecule expressed on most circulating leukocytes, including neutrophils. Engagement of L-selectin with endothelial-derived ligands initiates neutrophil tethering and rolling behaviour along luminal walls of post-capillary venules, constituting the first step of the multi-step adhesion cascade. There is a large body of evidence to suggest that signalling downstream of L-selectin can influence neutrophil behaviour: adhesion, migration and priming. This review will cover aspects of L-selectin form and function and introduce the "triad of L-selectin regulation", highlighting the inextricable links between adhesion, signalling and ectodomain shedding and also highlighting the cytosolic proteins that interconnect them...

Sudden cardiac arrest is a leading cause of death worldwide. Despite significant advances in resuscitation science since the initial use of external chest compressions in humans nearly 60 years ago, there continues to be wide variability in rates of successful resuscitation across communities. The American Heart Association (AHA) and European Resuscitation Council emphasise the importance of high-quality chest compressions as the foundation of resuscitation care. We review the physiological basis for the association between chest compression quality and clinical outcomes and the scientific basis for the AHA's key metrics for high-quality cardiopulmonary resuscitation...

Although prostate cancer can be surgical excised and effectively treated by androgen-deprivation therapy, radiotherapy, or chemotherapy, management of patients with advanced or drug-resistance prostate cancer stills remains a big trouble. Accumulated evidence indicated that miR-182 and Wnt/β-catenin function as tumor oncogene in the progression of a variety of tumors. However, little is known about how miR-182 regulates β-catenin signal molecular and impacts on the tumorigenesis of human prostate cancer. In this study, employing the analyses of qRT-PCR, we found that prostate cancer tissues expressed much more miR-182 than non-cancer tissues did...

BACKGROUND: Nanoparticle albumin-bound (nab)-paclitaxel was developed to improve paclitaxel solubility and does not need premedication to avoid infusion-related reactions associated with solvent-based (sb)-paclitaxel. We conducted a phase II trial to investigate the efficacy and safety of nab-paclitaxel plus ramucirumab combination therapy for previously treated advanced gastric cancer. PATIENTS AND METHODS: Patients with unresectable advanced gastric cancer refractory to first-line chemotherapy were administered nab-paclitaxel 100 mg/m2 intravenously on days 1, 8 and 15, plus ramucirumab 8 mg/kg intravenously on days 1 and 15 of a 28-day cycle...

Immunotherapy has shown encouraging results in lymphoma. Pre-clinical and clinical trials have proven checkpoint blockade, such as PD-1 antibody, as an effective treatment for lymphoma, including diffuse large B-cell lymphoma (DLBCL). Combination of checkpoint blockades has emerged as a new way to treat lymphoma, however, the status of checkpoints expression and their function in DLBCL has not been fully elucidated yet. In this study, we examined the expression of BTLA, PD-1, TIM-3, LIGHT and LAG-3 in tumor micro-environmental T cells of DLBCL using flow cytometry, and compared the cytotoxicity and differentiation status of BTLA+ and BTLA- T-cells...

Multiplexed isothermal amplification and detection of nucleic acid sequences and biomarkers is of increasing importance in diverse areas including advanced diagnostics, food quality control and environmental monitoring. Whilst there are several very elegant isothermal amplification approaches, multiplexed amplification remains a challenge, requiring careful experimental design and optimisation, from judicious primer design in order to avoid the formation of primer dimers and non-specific amplification, applied temperature as well as the ratio and concentration of primers...

Helicobacter pylori (H. pylori) infects approximately half the world's population and is especially prevalent in the developing world. H. pylori is as an important cause of global ill health due to its known etiological role in peptic ulcer disease, dyspepsia, gastric cancer, lymphoma and, more recently recognised in iron deficiency anemia and idiopathic thrombocytopenic purpura. Increased antibiotic usage worldwide has led to antibiotic resistance among many bacteria, including H. pylori, resulting in falling success rates of first-line anti-H...

BACKGROUND: In the vast majority of patients with obstructive hypertrophic cardiomyopathy and drug-refractory heart failure, surgical myectomy results in reversal of heart failure symptoms. However, a small patient subgroup fails to experience sustained postoperative improvement despite relief of left ventricular outflow obstruction. Clinical profile of such patients has not been well defined. METHODS: Consecutive obstructive hypertrophic cardiomyopathy patients undergoing myectomy at Tufts Medical Center for drug refractory NYHA III/IV heart failure symptoms, 2004 to 2017, were followed postoperatively for 2...

Despite therapeutic advances that have prolonged life, myocardial infarction (MI) remains a leading cause of death worldwide and imparts a significant economic burden. The advancement of treatments to improve cardiac repair post-MI requires the discovery of new targeted treatment strategies. Recent studies have highlighted the importance of the epicardial covering of the heart in both cardiac development and lower vertebrate cardiac regeneration. The epicardium serves as a source of cardiac cells including smooth muscle cells, endothelial cells and cardiac fibroblasts...

Antitumor immunity relies on the ability of the immune system to recognize tumor cells as foreign and eliminate them. An effective immune response in this setting is due to surveillance of tumor-specific antigens that induce an adaptive immune response resulting in T-cell mediated cytotoxicity. Immune checkpoint inhibitors, specifically those targeting the programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) axis, have demonstrated promising activity in non-small cell lung cancer (NSCLC). However, there remains a crucial need for better treatment strategies for the majority of patients with advanced NSCLC, particularly in the frontline setting...

With the growing incidence of closed schistosomiasis and uncommon presentations, there is a risk of the infection rate being underestimated. A study in Japan reported an unexplained case of endocarditis that was finally diagnosed as a complex Schistosoma japonicum infection; in the absence of advanced techniques, the diagnosis was delayed. We therefore set out to explore the incidence of Schistosoma mansoni in endocarditis patients coming from areas of Egypt where S. mansoni is endemic. We also investigated histopathological changes in the cardiac valves and the presence of cell-free parasite DNA (CFPD) in cardiac tissues of laboratory mice infected with S...

OBJECTIVE: Patients suffering from advanced disease face different care transitions. The transition from acute to palliative care is challenging and may lead to the discontinuity of care. Family caregivers become important sources of information, as patients begin to experience difficulties in coping with emotional transition events. The Care Transition Measure was developed to evaluate care transitions as experienced by the elderly. It has never been used in palliative care. The aim of this study was to test the validity and reliability of a modified version of the Palliative Care Transition Measure, specifically the Palliative Care Transition Measure for Caregivers (PCTM-C)...

Enzyme immobilization with a nanostructure material can enhance its stability and facilitate reusability. However, the apparent activity is often compromised due to additional diffusion barriers and complex interactions with the substrates and solvent molecules. The present study elucidates the effects of the surface hydrophobicity of nano-confinement on CO2 diffusion to the active site of human carbonic anhydrase II (CA), an enzyme that is able to catalyze CO2 hydration at extremely high turnover rates. Using the Markov-state model in combination with coarse-grained molecular dynamics simulations, we demonstrate that a hydrophobic cage increases CO2 local density but hinders its diffusion towards the active site of CA under confinement...

Crizotinib, an inhibitor of anaplastic lymphoma kinase (ALK), MET, and ROS1, is approved for treatment of patients with ALK-positive or ROS1-positive advanced non-small-cell lung cancer (NSCLC). However, ALK rearrangements are also implicated in other malignancies, including anaplastic large-cell lymphoma and inflammatory myofibroblastic tumors (IMTs). In this ongoing, multicenter, single-arm, open-label phase 1b study (PROFILE 1013; NCT01121588), patients with ALK-positive advanced malignancies other than NSCLC were to receive a starting dose of crizotinib 250 mg twice daily...

Blended learning is the integration of different learning approaches, new technologies and activities that combine traditional face-to-face teaching methods with authentic online methodologies. Although advances in educational technology have helped to expand the selection of different pedagogies, the teaching of anatomical sciences has been challenged by implementation difficulties and other limitations. These challenges are reported to include lack of time, costs, and lack of qualified teachers. Easy access to online information and advances in technology make it possible to resolve these limitations by adopting blended learning approaches...
