BACKGROUND: Lyme disease or Lyme borreliosis (LB) is the commonest vector-borne disease in the North America. It is an inflammatory disease caused by the bacterium Borrelia burgdorferi. The role of the inflammatory processes mediated by prostaglandins (PGs), thromboxanes and leukotrienes (LTs) in LB severity and symptoms resolution is yet to be elucidated. OBJECTIVES: We aim to systematically review and evaluate the role of PGs and related lipid mediators in the induction and resolution of inflammation in LB...

BACKGROUND: Right ventricular (RV) dysfunction predicts adverse outcome in peripartum cardiomyopathy (PPCM). We recently demonstrated beneficial effects associated with the prolactin release inhibitor bromocriptine at different doses when added to standard heart failure therapy in PPCM. Here, we evaluated for the first time the therapeutic potential of bromocriptine particularly in PPCM patients with RV involvement. METHODS: In this study, 40 patients with PPCM were included, of whom 24 patients had reduced RV ejection fraction (RVEF < 45%)...

Fine particulate matter (PM 2.5) is a well-known air pollutant threatening public health. Studies has confirmed that long-term exposure to the particles could reduce the pulmonary function, cause exacerbation of asthma and chronic obstructive pulmonary desease, and increase incidence and mortality of lung cancer. Bixin is a natural compound that is widely used as a food additive. Our previous studies demonstrated that bixin i.p. administration could protect against particles intratracheal exposure (56 days)-induced lung injury in an Nrf2-dependent manner...

BACKGROUND: While single (SLT) and double lung transplantation (DLT) are associated with differences in morbidity and mortality, the effects of transplant type on patient-reported outcomes are not widely reported and conclusions have differed. Previous studies compared mean health-related quality of life (HRQOL) scores but did not evaluate potentially different temporal trajectories in the context of longitudinal follow up. To address this uncertainty, this study is designed to evaluate longitudinal HRQOL after SLT and DLT with the hypothesis that temporal trajectories differ between SLT and DLT...

Tau oligomers are emerging as a key contributor to the synaptic dysfunction that drives cognitive decline associated with the clinical manifestation and progression of Alzheimer's disease (AD). Accordingly, there is ample consensus that interventions that target tau oligomers may slow or halt the progression of AD. With this ultimate goal in mind, in the present study, we investigated tau oligomer accumulation and its synaptic and behavioral consequences after an in vivo treatment with near infrared (NIR) light (600-1000 nm) in two transgenic mouse models, overexpressing human tau either alone (hTau mice) or in combination with amyloid beta (3xTgAD mice)...

PURPOSE: Laparoscopic-assisted anorectoplasty (LAARP) is a minimally invasive procedure in which the levator ani muscle is left to potentially improve postoperative fecal continence. This study aimed to retrospectively evaluate postoperative complications and long-term outcomes of fecal continence after LAARP and compare them to those after posterior sagittal anorectoplasty (PSARP). METHODS: Forty-five male patients with high and intermediate anorectal malformation (aged ≥ 4 years) who underwent LAARP or PSARP (LAARP 29, PSARP 16) from 1999 to 2013 were included...

BACKGROUND: Although chemotherapy-induced alopecia (CIA) is considered temporary, some patients report persistent alopecia several years after chemotherapy. There is, however, a paucity of long-term prospective data on the incidence and impact of permanent CIA (PCIA). The objective of our study was to estimate the long-term incidence of PCIA in a cohort of patients with breast cancer whose hair volume and density were measured prior to chemotherapy and who were followed for 3 years after chemotherapy...

REVIEW
Kelly E Carstens, Serena M Dudek
Synaptic plasticity in the hippocampus is thought to play a vital role in both the refinement of neuronal circuits during development and in learning in the mature brain. Synapses in hippocampal area CA1 are known for a robust capacity for long-term potentiation (LTP), whereas synapses in the stratum radiatum of hippocampal area CA2 are particularly resistant to such changes. Although we have yet to fully understand the mechanisms behind this resistance to plasticity, a number of genes and extracellular matrix components highly expressed in CA2 appear to function as molecular brakes on plasticity and develop postnatally in the rodent brain...

Duchenne Muscular Dystrophy is the most common paediatric neuromuscular disorder. Mutations in the DMD gene on the X-chromosome result in progressive skeletal muscle weakness as the main clinical manifestation. However, cardiac muscle is also affected, with cardiomyopathy becoming an increasingly recognised cause of morbidity, and now the leading cause of mortality in this group. The diagnosis of cardiomyopathy has often been made late due to technical limitations in transthoracic echocardiograms and delayed symptomatology in less mobile patients...

The colonial ascidian Didemnum vexillum is a high-profile marine invader, with a geographically widespread distribution after introductions to several temperate regions. D. vexillum has been the focus of several eradication and control programmes globally and the need for specific biological knowledge that relates to establishment processes, persistence, impacts and potential for spread remains. The present study describes temporal patterns of D. vexillum percent cover on experimental substrates over 1.5-years in relation to seasonality of substratum availability, in conjunction with key physical (i...

Water drainage is an important mitigation option for reducing CH4 (methane) emissions from residue-amended paddy soils. Several studies have indicated a long-term reduction in CH4 emissions, even after re-flooding, suggesting that the mechanism goes beyond creating temporary oxidized conditions in the soil. In this pot trial, the effects of different drainage patterns on straw-derived CH4 and CO2 (carbon dioxide) emissions were compared to identify the balance between straw-carbon CH4 and CO2 emissions influenced by soil aeration over different periods, including effects of drainage on emissions during re-flooding...

With the increasing global prevalence of diabetes mellitus, a significant rise in the number of patients suffering from non-healing wounds is expected. However, available treatments, such as revascularization surgery and foot care education are often insufficient to ensure satisfactory wound healing. One therapeutic strategy that has been identified as particularly promising utilizes adipose-derived stem cells (ADSCs). Through a comprehensive literature search of published and ongoing studies, we aimed to provide an overview of the experimental basis, the scientific background, and advances in the delivery of ADSCs for treating non-healing diabetic wounds...

Stroke leads to long term sensory, motor and cognitive impairments. Most patients experience some degree of spontaneous recovery which is mostly incomplete and varying greatly among individuals. The variation in recovery outcomes has been attributed to numerous factors including lesion size, corticospinal tract integrity, age, gender and race. It is well accepted that genetics play a crucial role in stroke incidence and accumulating evidence suggests that it is also a significant determinant in recovery. Among the number of genes and variations implicated in stroke recovery the val66met single nucleotide polymorphism (SNP) in the BDNF gene influences post-stroke plasticity in the most significant ways...

Anxiety disorder is a major psychiatric disorder characterized by fear, worry, and excessive rumination. However, the molecular mechanisms underlying neural plasticity and anxiety remain unclear. Here, we utilized a mouse model of anxiety-like behaviors induced by the chronic administration of corticosterone (CORT) to determine the exact mechanism of each region of the fear circuits in the anxiety disorders. Chronic CORT treated mice showed significant increase in anxiety-related behaviors as assessed by the elevated plus maze, light-dark, open-field, and marble-burying tasks...
