Genome-wide Association and Meta-analysis of Age-at-Onset in Parkinson Disease: Evidence From COURAGE-PD Consortium.

Neurology 2022 May 26. Epub 2022 May 26.

Sorbonne Université (SU) Unité Mixte de Recherche (UMR) 1127, INSERM U1127, CNRS UMR 7225, Institut du Cerveau et de la Moelle épinière, ICM, Paris, France.

Background And Objectives: Considerable heterogeneity exists in the literature concerning genetic determinants of the age of onset (AAO) of Parkinson's disease (PD), which could be attributed to lack of well-powered replication cohorts. The previous largest GWAS identified nd loci on chromosome (Chr) 4 with a significant influence on AAO of PD, these have not been independently replicated. The present study aims to conduct a meta-analysis of GWAS of PD AAO and validate previously observed findings in worldwide populations. Read More

Antibacterial activity of enrofloxacin loaded gelatin-sodium alginate composite nanogels against intracellular small colony variants.

J Vet Sci 2022 May;23(3):e48

Engineering Laboratory for Tarim Animal Diseases Diagnosis and Control, College of Animal Science, Tarim University, Alar 843300, China.

Background: The poor intracellular concentration of enrofloxacin might lead to treatment failure of cow mastitis caused by small colony variants (SASCVs).

Objectives: In this study, enrofloxacin composite nanogels were developed to increase the intracellular therapeutic drug concentrations and enhance the efficacy of enrofloxacin against cow mastitis caused by intracellular SASCVs.

Methods: Enrofloxacin composite nanogels were formulated by an electrostatic interaction between gelatin (positive charge) and sodium alginate (SA; negative charge) with the help of CaCl (ionic crosslinkers) and optimized by a single factor test using the particle diameter, zeta potential (ZP), polydispersity index (PDI), loading capacity (LC), and encapsulation efficiency (EE) as indexes.

Bufalin stimulates antitumor immune response by driving tumor-infiltrating macrophage toward M1 phenotype in hepatocellular carcinoma.

J Immunother Cancer 2022 May;10(5)

Institute of Infectious Disease, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai, 201203, People's Republic of China

Background: Immunotherapy for hepatocellular carcinoma (HCC) exhibits limited clinical efficacy due to immunosuppressive tumor microenvironment (TME). Tumor-infiltrating macrophages (TIMs) account for the major component in the TME, and the dominance of M2 phenotype over M1 phenotype in the TIMs plays the pivotal role in sustaining the immunosuppressive character. We thus investigate the effect of bufalin on promoting TIMs polarization toward M1 phenotype to improve HCC immunotherapy. Read More

Development and optimization of sustained-release drug-loaded intravesical inserts via semi-solid micro-extrusion 3D-printing for bladder targeting.

Int J Pharm 2022 May 23:121849. Epub 2022 May 23.

Institute of Pharmaceutics and Biopharmaceutics, Heinrich Heine University Düsseldorf, Universitätsstr. 1, 40225 Düsseldorf, Germany.

Discontinued treatment and non-adherence are oftentimes weaknesses of common first-line drug therapy against bladder conditions due to their negative side-effects. To overcome these limitations and increase patients' quality of life, intravesical therapies are continuously being explored. 3D-printing offers the possibility of freely tailoring drug delivery systems to manufacture indwelling devices that may administer drugs locally over an extended time and avoiding frequently repeated administrations while minimizing systemic side-effects.

J Pharmacol Toxicol Methods 2022 May 23:107184. Epub 2022 May 23.

Sophion Bioscience A/S, Ballerup, Copenhagen, Denmark. Electronic address:

There is no refuting that America's population is growing older: for the first time in US history, by 2034 older adults (defined as >65 years of age) are projected to outnumber children under the age of 18, representing approximately 70 million people or almost 25% of the population (Lloyd-Jones et al., 2010). Described as the "silver tsunami", this flood of older adults is driven by the baby boomers (people born after World War II, from 1946 to 1964): they are now reaching old age, living longer due to significant advances in healthcare coupled with a record low birth rate, resulting in a skewed elderly population demographic.

Laboratory of Experimental Neuropsychobiology, Department of Biochemistry and Molecular Biology, Natural and Exact Sciences Center, Federal University of Santa Maria, 1000 Roraima Avenue, Santa Maria, RS 97105-900, Brazil; Graduate Program in Biological Sciences: Toxicological Biochemistry, Federal University of Santa Maria, 1000 Roraima Avenue, Santa Maria, RS 97105-900, Brazil; The International Zebrafish Neuroscience Research Consortium (ZNRC), 309 Palmer Court, Slidell, LA 70458, USA. Electronic address:

Pathological anxiety is a set of diseases characterized by specific clinical manifestations and the use of alternative models may provide novel insights in translational neurobehavioral research. In zebrafish, the separate performance of novel tank and light dark tests in different order to assess anxiety using same animals may provide conflicting data due to the battery effect and/or time-drug-response and variability across tests. To improve data reliability, we aimed to characterize a novel behavioral paradigm to measure geotaxis and scototaxis as anxiety-like responses in the same trial. Read More

Developing new and efficient technologies for environmental remediation is becoming significant due to the increase in global concerns such as climate change, severe epidemics, and energy crises. Air pollution, primarily due to increased levels of HS, SO, NH, NO, CO, volatile organic compounds (VOC), and particulate matter (PM) in the atmosphere, has a significant impact on public health, and exhaust gases harm the natural sulfur, nitrogen, and carbon cycles. Similarly, wastewater discharged to the environment with metal ions, herbicides, pharmaceuticals, personal care products, dyes, and aromatics/organic compounds is a risk for health since it may lead to an outbreak of waterborne pathogens and increase the exposure to endocrine-disrupting agents.
