A series of salicylanilide compounds was previously identified as antibacterial agents that inhibit the peptidoglycan formation. To find the exact binding mode, we synthesized a benzophenone-containing salicylanilide compound (1) and used it as a photoaffinity probe to label Acinetobacter baumannii penicillin-binding protein (PBP1b). After incubation and photo-irradiation, the labeled protein was subjected to trypsin digestion, dialysis enrichment, LC-ESI-MS/MS analysis, and Mascot search to reveal an octadecapeptide sequence RQLRTEYQESDLTNQGLR that was labeled at E372.

The treatment of heroin addiction is a complex process involving changes in addictive behavior and brain functioning. The goal of this study was to explore the brain default mode network (DMN) functional connectivity using resting-state functional magnetic resonance imaging (rs-fMRI) and decision-making performance based on the Cambridge gambling task in heroin-dependent individuals undergoing methadone treatment (MT, = 11) and medication-free faith-based therapeutic community program (TC, = 11). The DMN involved the medial prefrontal cortex (mPFC), left inferior parietal lobe (IPL), right inferior parietal lobe (IPL), and posterior cingulate cortex (PCC) subregions for all participants in both the MT and TC groups.

Luteolin is a flavonoid that has been identified in many plant tissues and exhibits chemopreventive or chemosensitising properties against human breast cancer. However, the oncogenic molecules in human breast cancer cells that are inhibited by luteolin treatment have not been identified. This study found that the level of cyclin E2 (CCNE2) mRNA was higher in tumour cells (4.

Objective: To study the effects of Huannao Yicong Recipe (HNYCR)extract on the learning and memory ability, and the expressions of amyloid precursor protein (APP), beta-site APP-cleaving enzyme 1 (BACE1), presenilin-1 (PS-1), and beta amyloid protein (Abeta)in hippocampus CA1 area of APP transgenic mice, and to explore its mechanisms for treating Alzheimer's disease (AD).

Methods: Totally 3-month-old APP695V7171 transgenic mice were used to establish the AD model in this research. They were randomly divided into the model group, the Donepezil group, the large dose HNYCR extract group, the small dose HNYCR extract group, and the normal control group (C57BL/6J mice), 15 in each group.

Objective: To observe the effect of Huannao Yicong Prescription (, HNYC, a Chinese medical compound) extract on β-amyloid precursor protein (APP) metabolic signal transduction related protein kinase C (PKC), tyrosine amyloid protein kinase (TrKA), and glycogen synthase kinase-3 (GSK-3) in brain tissue of transgenic mouse dementia model induced by APP.

Methods: Sixty dementia model transgenic 3-month-old mice induced by APP695V717I were randomly allocated in four groups: the model group (A), the Donepezil (0.65×10(-3) g·kg(-1)·(-1))-treated group (B), and the two HNYC-treated groups (C and D) with high dosage (2.

Objective: To observe the effect of early intervention using extract of Huannao Yicong Decoction (, HYD) on the pathological picture of hippocampus, neurocyte apoptosis, and associated regulatory genes in β-amyloid precursor protein (APP) transgenic mice model of dementia.

Methods: Sixty APP695(V7171) transgenic mice were randomly divided into four groups of 15. The model group was treated with distilled water, the positive control group was treated with donepezil (0.

Objective: To observe the effects of early intervention with effective components from a Chinese herbal formula (Huannao Yicong formula, HNYCF) on behavior and related indicators of cholinergic system in β-amyloid precursor protein (APP) transgenic mice.

Methods: Sixty 3-month-old APP695 V717I transgenic mice were randomly divided into model group, high-dose HNYCF group (2.80 g/(kg·d)), low-dose HNYCF group (1.

Objective: To study in vitro whether the bifidobacterium plays a role in the functioning of dendritic cell (DC) stimulating the proliferation of T lymphocyte, and has effect on the generation of cytokine secreted by the DC deriving from the normal adult peripheral blood monocyte.

Methods: Normal adult immature DCs were generated in induction from monocyte cultured with granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4). On the 7th day of cell culture, immature DCs were exposed to various dosage heat-killed bifidobacteria (100 microg/mL, 10 microg/mL), while the control group was exposed to the culture without heat-killed bifidobacterrium, LPS at 1 microg/mL was added to some cultures as positive control.

Objective: The aim of this study is designed to explore the anti-tumor effect of lipoteichoic acid (LTA) of Bifidobacterium on the expression of survivin in colon cancer LoVo cells and its possible regulatory mechanism.

Methods: The changes of survivin mRNA and protein in LoVo cells treated with LTA of Bifidobacterium were detected by RT-PCR and Western blot. Meanwhile, the expressions of pAKT (the key protein kinase in P13K/AKT signal transduction pathway), p53 and PTEN were measured by Western blot.

Aim: To explore the effect of bifidobacterial whole peptidoglycan (BWPG) on cellular immune response to recombinant hepatitis B surface antigen (rHBsAg).

Methods: BWPG was used as an adjuvant of rHBsAg to immunize BALB/c mice. The growth state and development of central lymphoid organ of immunized mice were observed.

Objective: To explore the mechanism of moxibustion arresting the pulmonary fibrosis and provide experimental basis for prevention and treatment of pulmonary fibrosis with acupuncture and moxibustion.

Methods: One hundred and forty SD rats were randomly assigned to 4 groups: a blank group, a model group, a moxibustion group and a prednisone group, 35 rats in each group. The 3 groups expect the blank group were injected with bleomycin via trachea to induce experimental pulmonary fibrosis model, and 7 days after modeling, they were treated with moxibustion at bilateral Feishu (BL 13) and Gaohuang (BL 43), 3 cones each point, once each day, 10 days constituting one therapeutic course with an interval of one day between courses.

Although pneumococcus is one of the most frequently encountered opportunistic pathogen in the world, the mechanisms responsible for its infectiveness have not yet been fully understood. In this paper, we have attempted to characterize the effects of pneumococcal transformation on the pathogenesis of the organism. We constructed three transformation-deficient pneumococcal strains, which were designated as Nos.
