[Protective Effect of Endogenous ω-3 Polyunsaturated Fatty Acid Against Cisplatin Induced Myelosuppression].

Objective: To investigate the protective effect of endogenous ω-3 polyunsaturated fatty acid (PUFA) against cisplatin-induced myelosuppression and the mechanism of reducing apoptosis in bone marrow nucleated cells using mfat-1 transgenic mice.

Methods: The experimental animals were divided into 4 groups: wild-type mice normal control group, mfat-1 transgenic mice normal control group, wild-type mice model group and mfat-1 transgenic mice model group. The mice in the model group were injected intraperitoneally with 7.

[Effects of Methionine Restriction on Proliferation, Cell Cycle, and Apoptosis of Human Acute Leukemia Cells].

Objective: To investigate the effects of methionine restriction on proliferation, cell cycle and apoptosis of human acute leukemia cells.

Methods: Cell Counting Kit-8 (CCK-8) assay was used to detect the effect of methionine restriction on HL-60 and Jurkat cells proliferation. The effect of methionine restriction on cell cycle of HL-60 and Jurkat cells was examined by PI staining.

Detection of Specific IgG-Antibodies Against in the Serum and Milk of Domestic Donkeys During Lactation in China: A Potential Public Health Concern.

is a worldwide zoonotic protozoan. Donkeys are often susceptible to many pathological agents, acting as carriers of pathogens for other animal species and humans. However, data on the prevalence of in donkeys during lactation and on the status of antibodies against in donkey milk are lacking.

[The Effect of Novel Phosphodiesterase 4 Inhibitor ZL-n-91 to the Proliferation of Leukemia Cells].

Objective: To investigate the inhibitory effects of novel phosphodiesterase 4 inhibitor ZL-n-91 to the proliferation of leukemia cells L1210 and K562.

Methods: CCK-8 method was used to detect the effect of ZL-n-91 to the proliferation of L1210 and K562 cells, and the proliferation rate, IC were calculated. The effects of ZL-n-91 to the cycle of L1210 and K562 cells was detected by PE single staining, and the effects of ZL-n-91 to the apoptosis of L1210 and K562 cells was detected by PE/7AA-D double staining.

Charge-driven tripod somersault on DNA for ratiometric fluorescence imaging of small molecules in the nucleus.

Although fluorescence tracing of small bioactive molecules in living cells has been extensively studied, it is still a challenging task to detect their variations in the nucleus mainly due to the impermeable nuclear membrane and nucleic acid interference. Herein, we take advantage of the nucleic acid enriched environment in the nucleus to establish a strategy, named "charge-driven tripod somersault on DNA", for ratiometric fluorescence imaging of small bioactive molecules in the nucleus. Taking SO derivatives as a typical target analyte, a tripodal probe has been constructed by conjugating two DNA binding groups containing a SO derivative reaction site.

A mitochondria-targeted iridium(iii)-based photoacid generator induces dual-mode photodynamic damage within cancer cells.

A mitochondria-targeted photodynamic therapy (PDT) agent was designed and synthesized. Upon light irradiation, it can produce photoacid and its photolysis products can further sensitize 1O2 generation, causing dual-mode (oxygen-independent and oxygen-dependent) photodynamic damage in mitochondria and killing cancer cells effectively even under hypoxic conditions.

A new cycloartane triterpenoid glycoside from Souliea vaginata.

One new cycloartane triterpenoid glycoside, soulieoside Q (1), together with four known compounds (2-5) were isolated from the ethanolic extract of the rhizomes of Souliea vaginata Maxim. The structure of the new compound was determined by extensive spectroscopic analysis including 1D and 2D NMR and HRESIMS, as well as chemical methods. Compound 1 was evaluated for its cytotoxic activities against HepG2 and A549 cancer cell lines.

Soulieoside O, a new cyclolanostane triterpenoid glycoside from Souliea vaginata.

A new cyclolanostane triterpenoid glycoside, soulieoside O (1), together with 25-O-acetylcimigenol-3-O-β-d-xylopyranoside (2) and cimigenol-3-O-β-d-xylopyranoside (3), was isolated from the rhizomes of Souliea vaginata. Their structures were characterized by spectroscopic analysis and chemical methods. The new compound showed moderate inhibitory activity against three human cancer cell lines with IC values of 9.

Transdermal Permeation and Anti-Inflammation Activities of Novel Sinomenine Derivatives.

Sinomenine is extracted from Sinomenii caulis (a traditional Chinese medicine), and it is used as the active ingredient in rheumatic arthritis treatments. It has been used in clinical applications for decades. However, there are some disadvantages, including low activity in transdermal permeation and a high dosage being clinically required.

[Long-term follow-up results of synovectomy for rheumatoid knee].

Objective: To continuously observe the long-term effects of synovectomy for improving joint damage and quality-of-life in patients with the rheumatoid knee.

Methods: Twenty-one consecutive patients with rheumatoid arthritis (RA) involving 24 knees underwent open synovectomy from November 1988 to January 1997 between November 1988 and January 1997. The changes in radiographic damage were assessed with Larsen score on plain films before and 6 months after surgery with subsequent annual assessment for 8 years, and the functional recovery of the patients was also evaluated with Health Assessment Questionnaire (HAQ) at the same time.
