A Role of Corazonin Receptor in Larval-Pupal Transition and Pupariation in the Oriental Fruit Fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae)

Qiu-Li Hou, Guy Smagghe et 7 al.

Feb 15, 2017 in Frontiers in Physiology
Corazonin (Crz) is a neuropeptide hormone, but also a neuropeptide modulator that is internally released within the CNS, and it has a widespread distribution in insects with diverse physiological functions. Here, we identified and cloned the cDNAs of Bactrocera dorsalis that encode Crz and its receptor CrzR. Mature BdCrz has 11 residues with a unique Ser11 substitution (instead of the typical Asn)...

Authenticity of pulmonary Lophomonas blattarum infection: A case report.

Shuang-Shuang Meng, Xu-Hong Lin et 6 al.

Jan 6, 2019 in World journal of clinical cases
Pulmonary protozoal infections are rare. A 28-year-old woman was admitted to hospital with chief complains of cough, sputum, and dyspnea. The clinical laboratory tests for blood revealed an increased eosinophil percentage of 31.3% and significantly elevated total IgE. The chest computed tomography scan revealed that bilateral bronchial walls were thickening, accompanied with patchy spots scattered...

Changes in the Microbiota and their Roles in Patients with Type 2 Diabetes Mellitus.

Qiao-Ling He, Xu-Hong Lin et 9 al.

Mar 9, 2023 in Current microbiology
An association between type 2 diabetes mellitus (T2DM) and gut microbiota is well established, but the results of related studies are inconsistent. The purpose of this investigation is to elucidate the characteristics of the gut microbiota in T2DM and non-diabetic subjects. Forty-five subjects were recruited for this study, including 29 T2DM patients and 16 non-diabetic subjects. Biochemical param...

Horizontal gene transfer via OMVs co carrying virulence and antimicrobial resistant genes is a novel way for the dissemination of carbapenem resistant hypervirulent Klebsiella pneumoniae

Ping Li, Wei Zhang et 10 al.

Dec 1, 2022 in Frontiers in Microbiology
Introduction The rapidly increased isolation rate of CR HvKP worldwide has brought great difficulties in controlling clinical infection. Moreover, it has been demonstrated that the transmission of drug resistant genes among bacteria can be mediated by outer membrane vesicles (OMVs), which is a new way of horizontal gene transfer (HGT). The transmission of virulence genes among bacteria has also be...

Bioactivity-guided Isolation of Antiproliferative Diterpenoids from Euphorbia kansui

Hong-Ying Wang, Ling-Yi Kong et 6 al.

Nov 14, 2011 in Phytotherapy Research
Cytotoxic assay guided multistep separation on the dichloromethane extract of the roots of Euphorbia kansui resulted in the isolation of 10 ingenol‐type diterpenoids (1–4 and 7–12), of which, 5‐O‐(2′E,4′E‐decadienoyl)‐20‐O‐acetylingenol (1) is a new compound, and two are jatrophane‐type diterpenoids (13–14). Interconversion of two pairs of positional ester isomers (1–4) in aqueous alcoholic soluti...

Identification and expression profiles of fifteen delta-class glutathione S-transferase genes from a stored-product pest, Liposcelis entomophila (Enderlein) (Psocoptera: Liposcelididae)

Tian-Xing Jing, Jin-Jun Wang et 5 al.

Apr 1, 2017 in Comparative Biochemistry and Physiology Part B
Glutathione S-transferases (GSTs) comprise a diverse family of enzymes found ubiquitously in aerobic organisms and they play important roles in insecticide resistance. In this study, we tested the sensitivities of Liposcelis entomophila, collected from four different field populations, to three insecticides. The results showed that the insects from Tongliang population had a relatively higher tole...


Novel Tirucallane-Type Triterpenoids from Aphanamixis grandifolia

Jun-Song Wang, Ling-Yi Kong et 5 al.

Nov 1, 2011 in Chemistry & Biodiversity
Phytochemical investigation on the stem bark of Aphanamixis grandifolia afforded five novel tirucallane‐type triterpenoids, (13α,14β,17α,23Z)‐25‐methoxy‐21,23‐epoxylanosta‐7,20(22),23‐triene‐3,21‐dione (1), (13α,14β,17α,23Z)‐21,23‐epoxylanosta‐7,20(22),23,25‐tetraene‐3,21‐dione (2), (3R,5R, 9R,10R,13S,14S,17S)‐17‐{(2R,3S,5R)‐5‐[(2S)‐3,3‐dimethyloxiran‐2‐yl]‐2,3,4,5‐tetrahydro‐2,5‐dimethoxyfuran‐3‐...
