A meeting of regional experts was convened in Manila, Philippines, to develop a resource-stratified chemotherapy-induced nausea and vomiting (CINV) management guideline. In patients treated with highly emetogenic chemotherapy in general clinical settings, triple therapy with a serotonin (5-hydroxytryptamine-3 [5-HT3]) antagonist (preferably palonosetron), dexamethasone, and aprepitant is recommended for acute CINV prevention. In resource-restricted settings, triple therapy is still recommended, although a 5-HT3 antagonist other than palonosetron may be used...

2',3'-iso-Benzoabscisic acid (iso-PhABA), an excellent selective abscisic acid (ABA) analog, was developed in our previous work. In order to find its more structure-activity information, some structural modifications were completed in this paper, including the substitution of phenyl ring and replacing the ring with heterocycles. Thus, 16 novel analogs of iso-PhABA were synthesized and screened with three bioassays, Arabidopsis and lettuce seed germination and rice seedling elongation. Some of them, i.e., 2',3'-iso-pyridoabscisic acid (iso-PyABA) and 2',3'-iso-franoabscisic acid (iso-FrABA), displayed good bioactivities that closed to iso-PhABA and natural (+)-ABA...

BACKGROUND: Currently, little evidence is available on the length and type of anticoagulation used for extended treatment for prevention of recurrent venous thromboembolism (VTE) in patients with unprovoked VTE who have completed initial oral anticoagulation therapy. OBJECTIVES: To compare the efficacy and safety of available oral therapeutic options (aspirin, warfarin, direct oral anticoagulants (DOACs)) for extended thromboprophylaxis in adults with a first unprovoked VTE, to prevent VTE recurrence after completion of an acceptable initial oral anticoagulant treatment period, as defined in individual studies...

Imprinted genes occur in discrete clusters that are coordinately regulated by shared DNA elements called Imprinting Control Regions. H19 and Igf2 are linked imprinted genes that play critical roles in development. Loss of imprinting (LOI) at the IGF2/H19 locus on the maternal chromosome is associated with the developmental disorder Beckwith Wiedemann Syndrome (BWS) and with several cancers. Here we use comprehensive genetic and genomic analyses to follow muscle development in a mouse model of BWS to dissect the separate and shared roles for misexpression of Igf2 and H19 in the disease phenotype...

The inhibition of cholinesterase (ChE) activity has been used as a biomarker of exposure to organophosphate and carbamate insecticides. ChE of nesting female green turtles (Chelonia mydas) were biochemically characterized using two substrates, acetylthiocholine iodide and butyrylthiocholine iodide, and three ChE inhibitors (eserine sulfate, BW284C51 and iso-OMPA). The results indicated that BChE is the predominant plasma ChE in female C. mydas, but with atypical properties that differ from those found in human BChE...

Candida albicans is well known as a major human fungal pathogen, but it is also a permanent resident of healthy gastrointestinal tracts. Recent studies have shown that the human gut microbial metabolome represents an interesting source of bioactive molecules with a significant degree of chemical diversity. Some of these bioactive molecules may have useful antivirulence activities. For instance, intestinal bacterial species belonging to the Lachnospiraceae family were found to secrete molecules that attenuate Salmonella pathogenicity and repress the expression of virulence genes...

Assessment of pharmacodynamic (PD) drug interactions is a cornerstone of the development of combination drug therapies. To guide this venture, we derive a general pharmacodynamic interaction (GPDI) model for ≥2 interacting drugs that is compatible with common additivity criteria. We propose a PD interaction to be quantifiable as multidirectional shifts in drug efficacy or potency and explicate the drugs' role as victim, perpetrator or even both at the same time. We evaluate the GPDI model against conventional approaches in a data set of 200 combination experiments in Saccharomyces cerevisiae: 22% interact additively, a minority of the interactions (11%) are bidirectional antagonistic or synergistic, whereas the majority (67%) are monodirectional, i...

Drug combinations acting synergistically to kill cancer cells have become increasingly important in melanoma as an approach to manage the recurrent resistant disease. AKT is a major target in this disease but its inhibitors are not effective clinically, which is a major concern. Targeting AKT in combination with WEE1 seems to have potential to make AKT based therapeutics effective clinically. Since agents targeting AKT and WEE1 have been tested individually in the clinic, the quickest way to move the drug combination to patients would be to combine them sequentially, enabling the use of existing phase-I clinical trial toxicity data...

Ozone is an atmospheric pollutant that causes lung inflammation and airway hyperresponsiveness. Ozone's effects occur in two distinct phases that are mediated by different populations of eosinophils. In the acute phase 1 day after exposure, mature airway-resident eosinophils alter parasympathetic nerve function that results in airway hyperresponsiveness. At this time point, the severity of hyperresponsiveness correlates with the number of eosinophils in close proximity to airway nerves, but not with eosinophils in bronchoalveolar lavage...

During metazoan development, Notch signaling drives spatially coordinated differentiation by establishing communication between adjacent cells. This occurs through either lateral inhibition, in which adjacent cells acquire distinct fates, or lateral induction, in which all cells become equivalent. Notch signaling is commonly activated by several distinct ligands, each of which drives signaling with a different efficiency upon binding to the Notch receptor of adjacent cells. Moreover, these ligands can also be distinctly regulated by Notch signaling...

Two key transmitters in the medial prefrontal cortex (mPFC), dopamine and acetylcholine, are believed to interact with each other to modulate local glutamatergic transmission, although molecular mechanisms underlying their crosstalk are poorly understood. Here we investigated effects of pharmacological manipulations of dopamine and muscarinic receptors on phosphorylation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in the adult rat mPFC in vivo. We found that an agonist selective for Gαs-coupled dopamine D1 receptors, SKF81297, increased AMPA receptor GluA1 subunit phosphorylation at a protein kinase A-sensitive site (S845), while SKF81297 had no effect on GluA1 phosphorylation at S831...

Several lines of evidence have indicated that Methamphetamine (METH) exposure leads to neurodegenerative changes in the dopaminergic neurons and subsequently may predispose users to motor deficit. On the other hand, there is a reciprocal regulation between the endocannabinoid and the dopaminergic systems. Previous studies also showed that the endocannabinoids are involved in the signaling mechanisms of various brain regions related to motor and cognitive functions. The cerebellum seems as a rational target to investigate the action of cannabinoids on motor coordination because of the high concentration of the cannabinoid receptor in the molecular layer of it and other regions involved in motor activity...

Cancer immunotherapies were approved in recent years, including immune checkpoint inhibitors. Experience with ipilimumab (CTLA-4 antagonist), nivolumab and pembrolizumab (PD-1 antagonists), and atezolizumab (PD-L1 antagonist) has shown that the impact on overall survival in cancer patients is paramount. Immune checkpoint inhibitors target the immune system and they can be applied across multiple cancers; the response rate is ranging from 20 to 40%. Many studies have shown that thyroid cancer (TC) cells produce cytokines and chemokines, inducing several tumor-promoting effects...

The growth factor midkine has been implicated in various biologic and pathologic events. It has been shown that the peripheral influence of midkine on cardiovascular regulation is due to an influence on the renin-angiotensin system. The nucleus tractus solitarii (NTS) is the primary integrative center for cardiovascular control and other autonomic functions in the central nervous system. However, the signaling mechanisms involved in midkine-mediated cardiovascular effects in the NTS remain unclear. In this study, we investigated whether the renin-angiotensin system and/ or N-methyl-D-aspartate (NMDA) receptor-calmodulin-eNOS signaling pathways were both involved in midkine-mediated blood pressure (BP) regulation in the NTS of Wistar-Kyoto rats...
