Chronic stressful events are key risk factors for major depressive disorder (MDD), yet some individuals exposed to stressful events do not develop MDD. This disparity suggests the significance of resilience to deleterious stress effects. However, the underlying molecular mechanisms of stress resilience are poorly understood. In the present study, the(More)
Four new lycodine-type alkaloids, namely 16-hydroxyhuperzine B (1), N-methyl-11-acetoxyhuperzine B (2), 8,15-dihydrolycoparin A (3) and (7S,12S,13R)-huperzine D-16-O-β-d-glucopyranoside (4), along with ten known analogues 5-14, were isolated from the whole plant of Lycopodiastrum casuarinoides. The structures of the new compounds were elucidated by means of(More)
The winter and summer microbial community structure in sediment samples obtained from the estuaries of the wastewater-polluted River Ou (DO and XO), River Feiyun (DF and XF), and River Ao (DA and XA) in the south of Zhejiang Province in China was determined using 454 pyrosequencing. Sediment samples (DD and XD) were also correspondingly collected near the(More)
Intraventricular hemorrhage is associated with poor functional outcomes in patients with intracerebral hemorrhage (ICH). We aimed to investigate the association between intraventricular hemorrhage and early hematoma expansion in patients with ICH. Patients with ICH who underwent a baseline CT scan within six hours after onset of symptoms were included. The(More)
MicroRNA-27a (miR-27a) is deemed as an oncogene in malignancies including colorectal cancer (CRC), and rs895819 within pre-miR-27a may affect its secondary structure, leading to its aberrant expression and dysfunction of its targeted gene. We investigated genotype and allele frequencies of the locus in 412 I-III stage CRC cases and 412 age- and sex-matched(More)
Previous studies have demonstrated inconsistent findings regarding the efficacy of bilateral vs. unilateral repetitive transcranial magnetic stimulation (rTMS) in treating major depressive disorder (MDD). Therefore, this meta-analysis was conducted to compare the efficacy of these two rTMS modalities. Data were obtained from seven randomized controlled(More)
Epimedium sagittatum (Sieb. et Zucc) Maxim is a member of the Berberidaceae family of basal eudicot plants, widely distributed and used as a traditional medicinal plant in China for therapeutic effects on many diseases with a long history. Recent data shows that E. sagittatum has a relatively large genome, with a haploid genome size of ~4496 Mbp, divided(More)
The title compound, C(20)H(26)O(6)S, synthesized by the reaction of 3-O-meth-oxy-methyl-16β-epiestriol and sulfonyl-diimidazole, is composed of a 3-meth-oxy-methyl group connected via two O atoms to a 16,17-O-sulfuryl-16-epiestriol group. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into [001] chains.
OBJECTIVE To investigate the Methionine Enkephalin (M-Enk) expression in lamina II of cat spinal cord and the atypical complex terminal (ACT) after complete dorsal rhizotomy. METHODS 10 male adult cats were divided into 2 groups after carrying out the complete dorsal rhizotomy: acute group, which survived 2 weeks; chronic group, which survived 2 months.(More)
