Xiang Zhao, Jinhua Wang, Lusheng Zhu, Weili Ge, Jun Wang
Antibiotics and the corresponding resistant bacteria and resistance genes (ARGs) are generally considered emerging pollutants. To assess the impacts of tetracycline (TC) and sulfonamide (SA) antibiotics that are eliminated with fecaluria as drug prototypes, farmland soil used to research long-term fertilization with chicken manure was collected at four sites in Shandong Province. In this study, the rates of bacterial drug resistance to the same antibiotic decreased with an increase in the concentration of that antibiotic, and the resistance rates to TCs were lower than those to SAs...

REVIEW
Karla A Ruiz-Ceja, Yolanda I Chirino
BACKGROUND: Lung cancer is the leading worldwide cancer with almost 1.5 million deaths every year. Some drugs for lung cancer treatment have been available on the market for decades, but novel drugs have emerged promising better outcomes, especially for Non-Small Cell Lung Cancer (NSCLC), which represents 75% of lung cancer cases. However, how much do drugs have evolved for NSCLC treatment? Are they sharing the same mechanism of action? AIM: In this review we analyzed how the approved drugs by Federal Drug Agency for NSCLC have advanced in the last four decades identifying shared mechanism of action of medicines against NSCLC treatment and some of the potential biomarkers for early detection...

The increasing prevalence of chronic kidney disease (CKD) and diabetes over the last decade has resulted in increasing numbers of frail older patients with a combination of these conditions. Current treatment guidelines may not necessarily be relevant for such patients, who are mostly excluded from the trials upon which these recommendations are based. There is a paucity of data upon which to base the management of older patients with CKD. Nearly all current guidelines recommend less-tight glycaemic control for the older population, citing the lack of proven medium-term benefits and concerns about the high short-term risk of hypoglycaemia...

Introduction.:  Intrathecal drug delivery systems (IDDSs) have dramatically improved analgesia and the functional status of cancer patients and those with chronic pain states. However, given the close proximity to the neuraxis and frequent concomitant use of antiplatelet or anticoagulant medications, this intervention is not without risk. The goal of this investigation was to determine the incidence of bleeding complications following IDDS placement. Methods.:  This is a retrospective review from 2005 through 2014 of adult patients undergoing IDDS implantation or revision at a tertiary care center...

Severe adverse systemic drug events occur commonly as a result of treatment of cancer patients. Nephrotoxicity of chemotherapeutic agents remains a significant complication limiting the efficacy of the treatment. A variety of renal disease and electrolyte disorders can result from the drugs that are used to treat malignant disease. The kidneys are a major elimination pathway for many antineoplastic drugs and their metabolites. Tumour lysis syndrome, an emergency in haematooncology, occurs most often after the initiation of cytotoxic therapy in patients with high-grade lymphomas and acute lymphoblastic leukaemia...

Background.: Glioblastoma (GBM), an aggressive brain tumor with frequent relapses and a high mortality, still awaits an effective treatment. Like many cancers, GBM cells acquire oncogenic properties, including metabolic reprogramming, vital for growth. As such, tumor metabolism is an emerging avenue for cancer therapy. One relevant target is the voltage-dependent anion channel 1 (VDAC1), a mitochondrial protein controlling cell energy and metabolic homeostasis. Methods...

Electronic cigarettes (e-cigarettes) are increasing in popularity with 19% of UK smokers reporting to have used them. The ability to regulate the evaporation temperature in newer electronic nicotine delivery systems (ENDS) facilitates the potential for use of these devices to 'vape' cannabis, novel psychoactive substances (NPS) and other recreational drugs. Vaping cannabis does have the potential to reduce tobacco use and combustible cannabis/tobacco-related disease, but with over one-third of UK adults reporting life-time use of recreational drugs and increasing e-cigarette uptake in adolescent groups the misuse of these devices poses a serious potential public health risk...

Aims: Monocytes/macrophages response plays a key role in post-infarction inflammation that contributes greatly to post-infarction ventricular remodeling and cardiac rupture. Therapeutic targeting of the GABAA receptor, which is enriched in monocytes/macrophages but not expressed in the myocardium, may be possible after myocardial infarction. Methods and results: After MI was induced by ligation of the coronary artery, C57BL/6 mice were intraperitoneally administered with one specific agonist or antagonist of the GABAA receptor (topiramate or bicuculline), in the setting of presence or depletion of monocytes/macrophages...

Cardiac disease is the leading cause of death in the developed world. Ventricular arrhythmias associated with myocardial ischaemia and/or infarction are a major contributor to cardiovascular mortality, and require improved prevention and treatment. Drugs, devices, and radiofrequency catheter ablation have made important inroads, but have significant limitations ranging from incomplete success to undesired toxicities and major side effects. These limitations derive from the nature of the intervention. Drugs are frequently ineffective, target the entire heart, and often do not deal with the specific arrhythmia trigger or substrate...

Mucorales are a group of basal fungi that includes the casual agents of the human emerging disease mucormycosis. Recent studies revealed that these pathogens activate an RNAi-based pathway to rapidly generate drug-resistant epimutant strains when exposed to stressful compounds such as the antifungal drug FK506. To elucidate the molecular mechanism of this epimutation pathway, we performed a genetic analysis in Mucor circinelloides that revealed an inhibitory role for the non-canonical RdRP-dependent Dicer-independent silencing pathway, which is an RNAi-based mechanism involved in mRNA degradation that was recently identified...

FDA issues Drug Safety Communications (DSCs) to alert health care professionals and the public about emerging safety information affecting prescription and over-the-counter drugs. News media may amplify DSCs, but it is unclear how DSC messaging is transmitted through the media. We conducted a content analysis of the lay media coverage reaching the broadest audience to characterize the amount and content of media coverage of two zolpidem DSCs from 2013. After the first DSC, zolpidem news stories increased from 19 stories/week in the preceding 3 months to 153 following its release...

RNA recombination is a major driving force for the evolution of RNA viruses and is significantly implicated in the adaptation of viruses to new hosts, changes of virulence, as well as in the emergence of new viruses including drug-resistant and escape mutants. However, the molecular details of recombination in animal RNA viruses are only poorly understood. In order to determine whether viral RNA recombination depends on translation of viral proteins, a non-replicative recombination system was established which is based on cotransfection of cells with synthetic bovine viral diarrhea virus (family Flaviviridae) RNA genome fragments either lacking the internal ribosome entry site required for cap-independent translation or lacking almost the complete polyprotein coding region...

Metal-organic frameworks (MOFs) have emerged as an important class of hybrid organic-inorganic materials. One of the reasons they have gained remarkable attention is attributed to the possibility of altering them by postsynthetic modification, thereby providing access to new and novel advanced materials. MOFs have been applied in catalysis, gas storage, gas separation, chemical sensing, and drug delivery. However, their bactericidal use has rarely been explored. Herein, we developed a two-step process for the synthesis of zirconium-based MOFs metalated with silver cations as a potent antibacterial agent...

Infectious or septic shock is induced when a toxic microorganism invades blood circulation in the human body. Emergency operation is an effective method for treating infectious shock in the early stages although the use of anesthesia is more complex due to the internal disorders caused by the disease. This study explored the effects of propofol and etomidate anesthesia on the cellular immune function (T lymphocyte subpopulation) of infectious shock patients, aiming to provide a basis for the selection of the proper anesthetic method...

INTRODUCTION AND AIMS: This study tested the measurement invariance of the Drinking Motives Questionnaire-Revised Short Form (DMQ-R-SF) in undergraduates across 10 countries. We expected the four-factor structure to hold across countries, and for social motives to emerge as the most commonly endorsed motive, followed by enhancement, coping and conformity motives. We also compared individualistic and collectivistic countries to examine potential differences in the endorsement of drinking motives when countries were divided according to this broad cultural value...
