Complex interspecific relationships between parasites and their insect hosts involve multiple factors and are affected by their ecological and evolutionary context. A parasitoid (Hymenoptera: Bethylidae) and an entomopathogenic fungus (Hypocreales: Cordycipitaceae) shared the same host in nature, (Coleoptera: Cerambycidae). They often encountered the semi-enclosed microhabitat of the host larvae or pupae.

Methods: Positron emission tomography with 2-[F]fluoro-2-deoxy-D-glucose (FDG-PET) was used to evaluate brain glucose metabolism, presented as the rate of 2-[F]fluoro-2-deoxy-D-glucose standardized uptake value ratio (FDG SUVR) in patients with AD or control subjects and in mice with or without thiamine deficiency induced by a thiamine-deprived diet. Brain amyloid-β (Aβ) deposition in patients with clinically diagnosed AD was quantified by performing assays using C-Pittsburgh compound B PET.
Aim: We evaluated the diagnostic value of blood thiamine metabolites for Alzheimer's disease (AD) by using positron emission tomography with C-Pittsburgh compound B (C-PiB PET) scanning.
Methods: Thirty-eight clinically diagnosed AD patients were voluntarily recruited. Blood thiamine metabolites were measured by high-performance liquid chromatography.
To date, we still lack disease-modifying therapies for Alzheimer's disease (AD). Here, we report that long-term administration of benfotiamine improved the cognitive ability of patients with AD. Five patients with mild to moderate AD received oral benfotiamine (300 mg daily) over 18 months.

Thiamine diphosphate (TDP) is a critical coenzyme for glucose metabolism and significantly reduced in brain and blood samples of patients with Alzheimer's disease (AD).
Aims: To explore the diagnostic value of the measurement of blood thiamine metabolites for AD.

Objective: To investigate the frequency of anaplastic lymphoma kinase (ALK) expression in non-small cell lung cancer (NSCLC) patients and its correlation with the clinicopathologic features.
Methods: ALK immunohistochemistry and ALK fluorescent in situ hybridization (FISH) were performed on formalin-fixed, paraffin-embedded tissue in 100 cases of NSCLCs between 2011 and 2013. Relevant clinicopathologic data were collected and correlated with ALK expression.
The subvastus and medial parapatellar approaches are 2 commonly performed techniques in total knee arthroplasty, but the optimal approach for total knee arthroplasty remains controversial. The purpose of this study was to compare the effectiveness and safety of the subvastus vs medial parapatellar approach.The PubMed, Embase, Cochrane Library, Inter-Services Intelligence Web of Knowledge, and Chinese Biomedical Literature databases were searched for eligible quasi-randomized, controlled and randomized, controlled trials.

In Arabidopsis (Arabidopsis thaliana), only one putative CCS gene (AtCCS, At1g12520) has been identified. The predicted AtCCS polypeptide contains three distinct domains: a central domain, flanked by an ATX1-like domain, and a C-terminal domain.
