Circulating PD1Vδ1γδ T Cell Predicts Fertility in Endometrial Polyp Patients of Reproductive-Age.

Clinically, immune cell function is correlated with pathogenesis of endometrial polyp (EP) and infertility of women of reproductive-age. However, the underlying immune cell hallmark in EP patients remains unclear. Here, we focused on analyzing circulating immune cells, and attempted to reveal the correlation between peripheral immune cell functional phenotypes and fertility in EP patients.

TMPyP-bound guanosine-borate supramolecular hydrogel as smart hemoperfusion device with real-time visualized/electrochemical bi-modal monitoring for selective blood lead elimination.

Blood lead poisoning is a universal and severe health problem that greatly threatens human health in various industries. Elimination of blood lead relying on chelating agents and combination with hemoperfusion adsorbents has achieved considerable progress, but it is still suffering from the compromised selectivity of adsorbents as well as in absence of real time monitoring during treatment. Herein, we proposed a selective blood lead adsorbent integrated with real-time visualized/electrochemical bi-modal monitoring based on TMPyP-bound guanosine-borate (GB) supramolecular hydrogel as potential smart hemoperfusion device.

[Blastocystis Infection in Pet Dogs in Selected Areas of Anhui and Zhejiang Provinces].

Objective: To determine the prevalence and subtypes of Blastocystis in pet dogs in Anhui and Zhejiang Provinces.

Methods: Pet dog fecal samples were collected from veterinary clinics in Baohe District of Hefei City, Xuanzhou District of Xuancheng City, Fengyang County and Mingguang City of Chuzhou City, Longzihu District of Bengbu City, Si County of Suzhou City in Anhui Province, as well as in Yuhang District of Hangzhou City in Zhejiang Province from April to December, 2013. Blastocystis was detected by microscopic examination as well as nested PCR and single-step PCR based on small subunit ribosomal DNA sequences.

Epidemic spreading on complex networks with general degree and weight distributions.

The spread of disease on complex networks has attracted wide attention in the physics community. Recent works have demonstrated that heterogeneous degree and weight distributions have a significant influence on the epidemic dynamics. In this study, a novel edge-weight-based compartmental approach is developed to estimate the epidemic threshold and epidemic size (final infected density) on networks with general degree and weight distributions, and a remarkable agreement with numerics is obtained.

Star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms: synthesis, drug delivery, and in vitro chemo/photodynamic therapy.

A novel star-shaped polymer, porphyrin-poly(L-lysine) dendrons (PP-PLLD), is synthesized by the click reaction between azido-modified porphyrin and propargyl focal point poly(L-lysine) dendrons. Its chemical structure is characterized by (1) H nuclear magnetic resonance, Fourier transform infrared spectroscopy, and gel permeation chromatography (GPC) is analyses etc. Due to its amphiphilic property, the obtained PP-PLLD has a low critical micelle concentration in an aqueous solution, and can load doxorubicin (DOX) with a loading amount of 64 μg mg(-1) .

BJ-B11, a novel Hsp90 inhibitor, induces apoptosis in human chronic myeloid leukemia K562 cells through the mitochondria-dependent pathway.

In the past few years heat shock protein 90 (Hsp90) inhibitors have been reported to possess significant antitumor activity. We investigated, for the first time, the antitumor activity of a novel Hsp90 inhibitor 2-(4-acetyloxycyclohexylamino)-4-(3, 6, 6-trimethyl-4-oxo-4, 5, 6, 7-tetrahydro-1H-indazol-1-yl)-benzamide (BJ-B11) and the molecular mechanism underlying the apoptosis it induces in human chronic myeloid leukemia K562 cells. The results revealed that BJ-B11 triggered growth inhibition in K562 cells and other malignant cell lines in vitro with only minor toxicity in a normal human cell line.

[Effects of heparin and anticardiolipin antibodies positive serum from patients with recurrent pregnancy loss on proliferation of BeWo cells].

Objective: To investigate the effects of anticardiolipin antibodies positive serum from patients with recurrent pregnancy loss on the proliferation of BeWo cells as well as the modulation of heparin on the growth of BeWo cell.

Methods: Thirty patients with recurrent pregnancy loss whose anticardiolipin antibodies were positive and thirty healthy women with a history of term delivery were selected. Their sera were separately added to BeWo cell culture systems which contained either heparin or not.

Epidemic spreading in complex networks.

The study of epidemic spreading in complex networks is currently a hot topic and a large body of results have been achieved. In this paper, we briefly review our contributions to this field, which includes the underlying mechanism of rumor propagation, the epidemic spreading in community networks, the influence of varying topology, and the influence of mobility of agents. Also, some future directions are pointed out.
