Weeping forsythia is an important ornamental, ecological and medicinal plant. Brown leaf spots limit the large-scale production of weeping forsythia as a medicinal crop. Alternaria alternata is a pathogen causing brown leaf spots in weeping forsythia; however, its pathogenesis and the immune response mechanisms of weeping forsythia remain unclear.

Twenty patients diagnosed as end-stage ankle arthritis with large talar cysts between 04/2010 and 02/2016 were randomly divided into experimental group (10 cases) and conventional group (10 cases) by random number method. Patients in the experimental group were treated with ankle arthrodesis combined with a concomitant procedure of mosaic bone autograft transplantation, the conventional group under the ankle arthrodesis.
View Article and Find Full Text PDFLithium (Li) metal is deemed as an ideal and promising star anode for high energy storage but its application still is impeded due to uncontrollable Li dendrite growth and tremendous dimension change. Although the flexible and conductive three-dimensional (3D) skeleton can improve the structural and interfacial stability of Li anode, its inherently lithiophobic feature usually brings a high nucleation barrier, uneven Li flux, and large concentration polarization, leading to inhomogeneous Li plating/stripping. Here, we develop target material (denoted as MoC NPs@CC) consisting of well-distributed molybdenum carbide nanoparticles (MoC NPs) with intrinsic lithiophilicity serving as lithiophilic seeds implanted onto the carbon cloth, breaking the dilemma of ordinary 3D conductive skeletons.

Herein, α-MnS nanoparticles (NPs) are in situ encapsulated into N,S-NTC, preparing an advanced anode material (α-MnS@N,S-NTC) for lithium-ion/sodium-ion batteries (LIBs/SIBs). It is for the first time revealed that electrochemical α → β phase transition of MnS NPs during the 1st cycle effectively promotes Li-storage properties, which is deduced by the studies of ex situ X-ray diffraction/high-resolution transmission electron microscopy and electrode kinetics.

However, it is not yet known whether electroencephalography can predict development of post-cerebral infarction depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Scale assessment to analyze the relationship between electroencephalography and post-cerebral infarction depression.

Methods: The clinical data of patients with osteoporotic vertebral compression fractures who underwent unilateral vertebroplasty from January 2012 to January 2015 was retrospectively analyzed. Of them, 56 cases including 22 males and 34 females aged from 60 to 78 years old were treated by PVP operation; Fouty-eight cases including 17 males and 31 females aged from 61 to 79 years old were treated by PKP operation; Forty-three cases including 15 males and 28 females aged from 60 to 76 years old were treated by manipulative reduction PVP operation.
In this work, oxygen-deficient anatase TiO nanosheets (A-TiO NSs) are proposed as a substrate to improve the electrochemical properties of sulfur electrodes for lithium-sulfur (Li-S) batteries. The A-TiO NSs are prepared by partly reducing pristine TiO nanosheets (A-TiO NSs) in NaBH solution. With some oxygen vacancies on the surface of the TiO nanosheets, A-TiO NSs not only promote electronic transfer, but also act as more effective polysulfide reservoirs to minimize the dissolution of lithium polysulfides (LiPSs) than the A-TiO NSs control.

Methods: In this retrospective controlled study, 69 cases with lumbar spondylolytic spondylolisthesis treated in Qilu hospital from April to November 2014 were randomly assigned to Wiltse approach (31 cases, 16 male, 15 female; mean age 45.1 years) and traditional approach groups (38 cases, 21 male, 17 female; 47.
Fe/N/C is a promising non-Pt electrocatalyst for the oxygen reduction reaction (ORR), but its catalytic activity is considerably inferior to that of Pt in acidic medium, the environment of polymer electrolyte membrane fuel cells (PEMFCs). An improved Fe/N/C catalyst (denoted as Fe/N/C-SCN) derived from Fe(SCN)3, poly-m-phenylenediamine, and carbon black is presented. The advantage of using Fe(SCN)3 as iron source is that the obtained catalyst has a high level of S doping and high surface area, and thus exhibits excellent ORR activity (23 A g(-1) at 0.

Pretreatment with taurine zinc (50, 100 or 200mg/kg) SDs dose-dependently protected rat gastric mucosa against cold-restraint stress (CRS)-induced gastric injury, and significantly attenuated increases in gastric mucosal H(+)K(+)-ATPase activity and lipid peroxidation and enhanced SOD activity. Taurine zinc also inhibited CRS-induced elevation of the serum stress hormones adrenocorticotropic hormone and corticosterone and upregulated HSP70 expression in the gastric mucosa.

A novel Zn(II)-curcumin complex was synthesized and its effects against cyclophosphamide (CP)-induced reproductive damage were compared with curcumin. Oral administration of Zn(II)-curcumin significantly prevented CP-induced elevation of malondialdehyde (MDA) level and reductions in superoxide dismutase (SOD) activity and glutathione (GSH) content in mouse testis.

This study is to investigate the effect of anterior cervical discectomy with internal fixation and fusion at different levels on adjacent segments in rabbits. Sixty New Zealand rabbits were randomly divided into four groups, one control group and three model groups, with 15 in each group. Each group underwent anterior cervical internal fixation and fusion at C3-4, C4-5, and C5-6 levels respectively.

The aim of this study was to investigate the possible mechanisms underlying the anti-ulcerogenic effects of the Zn(II)-curcumin complex, a curcumin derivative, on the healing of acetic acid-induced gastric ulcers in rats. The severely ulcerated gastric mucosa of control animals had a lower glutathione level (GSH) and superoxide dismutase activity (SOD), and increased malondialdehyde (MDA) content compared to sham operated rats (P<0.

Chronic fatigue syndrome (CFS) is a relatively new condition of unknown etiology. Research suggests that psychosocial factors such as perceived social support, life stress, and acculturation may significantly influence individuals who are prone to CFS. For 57 Chinese American individuals initially diagnosed with CFS, those who recovered after one year reported lower levels of life stress than those who did not recover.
