Association Between Gastroesophageal Reflux Disease and Laryngeal Disorders: Real-World Evidence.

Objective: The association between gastroesophageal reflux disease (GERD) and laryngeal disorders remains debatable, although it has been the focus of extensive clinical and laboratory research. We conducted this study to obtain evidence on the association.

Study Design: Population-based cohort study.

Astragalus Polysaccharides and Metformin May Have Synergistic Effects on the Apoptosis and Ferroptosis of Lung Adenocarcinoma A549 Cells.

Astragalus polysaccharides (APSs), the compounds extracted from the common herb Astragalus membranaceus, have been extensively studied for their antitumor properties. In this study, we investigated the effect of APS on lung adenocarcinoma A549 cells. The effects of APS and the anti-diabetic drug metformin on apoptosis and ferroptosis were compared.

Context-specific variation and repeatability in behavioral traits of bent-wing bats.

Animals may show consistent among-individual behavioral differences over time and in different contexts, and these tendencies may be correlated to one another and emerge as behavioral syndromes. The cross-context variation in these behavioral tendencies, however, is rarely explored with animals in contexts associated with different locomotion modes. This study assessed the variation and repeatability in behavioral traits of bent-wing bats Miniopterus fuliginosus in southern Taiwan, and the effects of contextual settings associated with locomotion mode.

Develop companion radiopharmaceutical YKL40 antibodies as potential theranostic agents for epithelial ovarian cancer.

Epithelial ovarian cancer (EOC) is usually diagnosed at an advanced stage and has poor prognosis. Theranostic agents are the current trend in drug development, but are lacking in EOC. YKL40 is predominantly expressed and involved in tumorigenesis in EOC.

Pharmacological and Chemical Potential of (Orchidaceae): A Narrative Review.

Orchidaceae is one of the largest families of flowering plants with more than 27,000 accepted species, and more than 31,000-35,000 species are estimated to exist in total. The orchid (Pers.) Ames, having ornamental and medicinal value, is widely distributed throughout Asia and Oceania.

Effects of host state and body condition on parasite infestation of bent-wing bats.

Background: Ectoparasites inhabit the body surface or outgrowths of hosts and are usually detrimental to host health and wellbeing. Hosts, however, vary in quality and may lead ectoparasites to aggregate on preferred hosts, resulting in a heterogeneous distribution of parasite load among hosts.

Results: We set out to examine the effects of host individual state and body condition on the parasite load of multiple nycteribiid and streblid bat flies and Spinturnix wing mites on eastern bent-wing bats Miniopterus fuliginosus in a tropical forest in southern Taiwan.

Hyaluronan-Loaded Liposomal Dexamethasone-Diclofenac Nanoparticles for Local Osteoarthritis Treatment.

Osteoarthritis (OA) remains one of the common degenerative joint diseases and a major cause of pain and disability in older adult individuals. Oral administration of non-steroidal anti-inflammatory drugs (NSAIDs) (such as diclofenac, DIC) or intra-articular injected gluco-corticosteroids (such as dexamethasone, DEX) were the conventional treatment strategies for OA to reduce joint pain. Current limitations for both drugs including severe adverse effects with risks of toxicity were noted.

Effect of valproic acid on overall survival in patients with high-grade gliomas undergoing temozolomide: A nationwide population-based cohort study in Taiwan.

High-grade gliomas (HGGs) are a rapidly progressive and highly recurrent group of primary brain tumors. Despite aggressive surgical resection with chemoradiotherapy, prognoses remained poor. Valproic acid (VPA), a histone deacetylase inhibitor has shown the potential to inhibit glioma cell growth in vitro through several diverse mechanisms.

Liposomal dexamethasone-moxifloxacin nanoparticle combinations with collagen/gelatin/alginate hydrogel for corneal infection treatment and wound healing.

Infectious keratitis is still one of the major causes of visual impairment and blindness, often affecting developing countries. Eye-drop therapy to reduce disease progression is the first line of treatment for infectious keratitis. The current limitations in controlling ophthalmic infections include rapid precorneal drug loss and the inability to provide long-term extraocular drug delivery.

Characterization of electrospun nanofiber matrices made of collagen blends as potential skin substitutes.

Collagen and its blends, collagen/polyvinyl alcohol (PVA) and collagen/chitosan/PVA, were made into nanofibers by electrospinning. The nanofibrous matrices were evaluated for their potential as skin substitutes. The addition of PVA to collagen increased the swelling ratio of the nanofibers, their Young's modulus, strain at break and ultimate tensile strength.

Flavanone and diphenylpropane glycosides and glycosidic acyl esters from Viscum articulatum.

Seven new compounds including three flavanone glycosides, visartisides A-C (1-3), three glycoside acyl esters, visartisides D-F (4-6), and one diphenylpropane glycoside, (4'-hydroxy-2',3',6',3''-tetramethoxy-1,3-diphenylpropane)-4''-O-beta-d-glucopyranoside (7), along with four known flavanone glycosides (8-11) were isolated from the leaves and stems of Viscum articulatum. The structure elucidation of 1-7 was based on spectroscopic data analysis. Biological evaluation showed that 1, 2, and 10 exhibited antioxidant activity using a DPPH method and that compounds 1, 3, and 11 were active in a lipopolysaccharide-induced nitric oxide assay.

Labdane diterpenoid glycosides from Alpinia densespicata and their nitric oxide inhibitory activities in macrophages.

Four new labdane diterpene glycosides (1-4) named alpindenosides A, B, C, and D, two new norditerpene glycosides (5, 6) named noralpindenosides A and B, and three known flavonoid glycosides (7-9) have been isolated from the stems of Alpinia densespicata. Structural elucidation of compounds 1-6 was based on spectroscopic data. Compounds 1-9 all exhibited moderate NO inhibitory activities, whereas they were noncytotoxic at 20 microM against several human tumor cell lines.

Cytotoxic constituents from Podocarpus fasciculus.

A new diterpene, 16-hydroxy communic acid (1), along with thirty one known compounds including five norditerpenes (2-6), twenty two flavonoids containing four biflavonoids (7-10), nine monoflavonoids (11-19) and nine flavanoid glycosides (20-28), as well as four phenolic constituents (29-32) were isolated from the 95% ethanolic extract of Podocarpus fasciculus. The structure of 1 was elucidated using spectral methods. Of these isolates, nagilactone C (2) showed the most significant inhibitory effects against DLD cells (human colon carcinoma) (ED(50)=2.

Two novel sesquiterpene lactones, cytotoxic vernolide-A and -B, from Vernonia cinerea.

Bioassay-directed fractionation of an ethanolic extract of stems of Vernonia cinerea has resulted in the isolation of two novel sesquiterpene lactones, vernolide-A and -B. Their structures were elucidated on the basis of spectroscopic analysis. Biological evaluation showed that vernolide-A demonstrated potent cytotoxicity against human KB, DLD-1, NCI-661, and Hela tumor cell lines (ED(50)=0.
