REVIEW
David M G Halpin
Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy...

The main purpose of this study was to address the performance of virtual screening methods based on ligands and the protein structure of acetylcholinesterase (AChE) in order to retrieve novel human AChE (hAChE) inhibitors. In addition, a protocol was developed to identify novel hit compounds and propose new promising AChE inhibitors from the ZINC database with 10 million commercially available compounds. In this sense, 3D similarity searches using rapid overlay of chemical structures and similarity analysis through comparison of electrostatic overlay of docked hits were used to retrieve AChE inhibitors from collected databases...

Immune checkpoint inhibitors (ICPIs) have recently emerged as a novel treatment for cancer. These agents, transforming the field of oncology, are not devoid of toxicity and cause immune-related side effects which can involve any organ including the nervous system. In this study, we present 9 patients (7 men and 2 women) with neurologic complications secondary to ICPI treatment. These included meningoencephalitis, limbic encephalitis, polyradiculitis, cranial polyneuropathy, myasthenic syndrome and myositis...

Tumor-reactive T lymphocytes can promote the regression of established tumors. However, their efficacy is often limited by immunosuppressive mechanisms that block T cell accumulation or function. ACT provides the opportunity to ameliorate immune suppression prior to transfer of tumor-reactive T cells to improve the therapeutic benefit. We evaluated the combination of lymphodepleting whole body irradiation (WBI) and agonist anti-CD40 (αCD40) antibody on control of established autochthonous murine neuroendocrine pancreatic tumors following the transfer of naïve tumor-specific CD8 T cells...

Hepatocyte nuclear factor 4-alpha (HNF4α) is a well-established master regulator of liver development and function. Restoration of HNF4α can treat multiple liver disorders and liver cancers. To date, HNF4α is still "undruggable" due to lack of known activating ligands. Thus, understanding the regulatory mechanism of HNF4α expression may help develop an alternative approach to modulate HNF4α protein levels. G-quadruplexes (G4) are non-canonical stable secondary structures discovered mostly in the promoters of oncogenes...

BACKGROUND: Early detection of Alzheimer's disease (AD) pathology is a serious challenge for both diagnosis and clinical trials. The aspartyl protease, Cathepsin D (CatD), is overexpressed in AD and could be a biomarker of disease. We have previously designed a unique contrast agent (CA) for dual-optical and magnetic resonance imaging of the activity of the CatD class of enzymes. OBJECTIVE: To compare the uptake and retention of a novel, more sensitive, and clinically-translatable 68Ga PET tracer targeting CatD activity in 5XFAD mice and non-Tg littermates...

BACKGROUND: In patients with chronic low back pain (CLBP), postural control is a demanding task in terms of attention. Although the attentional demands of postural control have been investigated in these patients, the attentional demands of postural recovery during dual task performance have not been evaluated in patients with nonspecific CLBP. OBJECTIVE: To investigate the effect of dual tasking on anticipatory and compensatory postural adjustments in response to an external perturbation in patients with nonspecific CLBP...

Abnormal concentrations of ATP are associated with many diseases and cancers, and quantitative detection of ATP is thus of great importance for disease diagnosis and prognosis. In the present work, we report a new dual recycling amplification sensor integrated with catalytic hairpin assembly (CHA) to achieve high sensitivity for fluorescent detection of ATP. The association of the target ATP with the aptamer beacons causes the allosteric structure switching of the aptamer beacons to expose the toehold regions, which hybridize with and unfold the fluorescently quenched hairpin signal probes (HP1) to recycle the target ATP and to trigger CHA between HP1 and the secondary hairpin probes (HP2) to form HP1/HP2 duplexes...

OBJECTIVE: The prevalence of Alzheimer's disease and Parkinson's disease increases with the raising number of elderly, which will be a challenging situation for the healthcare systems and society in the future. There is evidence that there are modifiable risk-factors e.g. physical activity for these diseases. Here, we study the interaction between sports inactivity with prodromal markers for neurodegeneration. PATIENTS AND METHODS: We investigated 667 neurologically healthy individuals cross-sectional and a subgroup longitudinal over six years...

Prevailing knowledge links chronic low-grade inflammation in the adipose tissue to obesity and its associated metabolic complications. In this study, we evaluated immunometabolic effects of a recently launched dual peroxisome proliferator-activated receptor (PPAR) α & γ agonist 'Saroglitazar' in a mouse model of diet-induced obesity (DIO). Body composition analysis revealed that saroglitazar treatment promoted hepatic weight gain, while attenuated epididymal white adipose tissue (eWAT) mass in DIO. In the eWAT of saroglitazar treated mice, histological analysis showed reduced adipocyte hypertrophy and matrix deposition (picrosirius red staining)...

Tumor-associated macrophages (TAMs) and angiogenesis are increasingly considered as the pivotal factors that affect tumor progress. Herein, we developed the paclitaxel (PTX)-loaded nanoparticles (NP/PTX) and decorated it with an innovative peptide YI (YINP/PTX) for simultaneously targeting delivery of drug to TAMs and angiogenesis. We demonstrated that the modification of YI peptide significantly enhanced the internalization of nanoparticles by cells, accumulation of nanoparticles in tumor tissues, but down regulated the distribution of them in normal tissues especially the liver...

Bone strength is affected not only by bone mineral density (BMD) and bone microarchitecture but also its microenvironment. Recent studies have focused on the role of marrow adipose tissue (MAT) in the pathogenesis of bone loss. Osteoblasts and adipocytes arise from a common mesenchymal stem cell within bone marrow and many osteoporotic states, including aging, medication use, immobility, over - and undernutrition are associated with increased marrow adiposity. Advancements in imaging technology allow the non-invasive quantification of MAT...

Aphids are pests of chrysanthemum that employ plant volatiles to select host plants and ingest cell contents to probe host quality before engaging in prolonged feeding and reproduction. Changes in volatile and non-volatile metabolite profiles can disrupt aphid-plant interactions and provide new methods of pest control. Chrysanthemol synthase (CHS) from Tanacetum cinerariifolium, represents the first committed step in the biosynthesis of pyrethrin ester insecticides, but no biological role for the chrysanthemol product alone has yet been documented...

BACKGROUND: Macrovascular atherosclerosis is an important long-term complication of type 2 diabetes mellitus. Concurrent dyslipidaemia acts as an additional risk factor for these complications. Hypovitaminosis D has been associated with adverse cardiovascular events. These modifiable risk factors of cardiovascular disease are inter-related. In the presence of an increasing incidence of type 2 diabetes mellitus and its associated metabolic abnormalities and widespread vitamin D deficiency in Pakistan, this association needs to be investigated...

Blackleg disease of Brassica napus caused by Leptosphaeria maculans (Lm) is largely controlled by deploying race-specific resistance (R) genes. However, selection pressure exerted by R genes causes Lm to adapt and give rise to new virulent strains through mutation and deletion of effector genes. Therefore, knowledge of effector gene function is necessary for effective management of the disease. Here we report cloning of Lm effector AvrLm9 that is recognised by the resistance gene Rlm9 in B. napus cultivar Goéland...

BACKGROUND: Psoriasis is a chronic T cell-mediated skin disease with marked social and economic burdens. Current treatments are unsatisfactory, with unpredictable remission times and incompletely understood modes of action. Recent advances in our understanding of the pathogenesis of psoriasis identify the imbalance between CD4+ T effector cells, particularly the T helper (Th) 17 subset, and regulatory T cells (Treg) as key to the development of psoriatic lesions, and therefore a novel therapeutic target...

INTRODUCTION: Previous analyses concluded that patients initiating treatment with sitagliptin are older and have more comorbidities than patients initiating treatment with other oral antihyperglycemic agents (OAHAs). However, these studies focused on the general population or subjects ≤ 65 years of age. We sought to compare differences in baseline characteristics of elderly patients (≥ 65 years of age) with T2DM initiating sitagliptin vs. non-DPP-4 inhibitor (non-DPP-4i) OAHA in the MarketScan® Medicare Supplemental Database...
