Computer tomography-guided negative pressure drainage treatment of intrathoracic esophagojejunal anastomotic leakage: A case report.

Background: Esophagojejunal anastomotic leakage (EJAL) is a serious and potentially crucial complication of total gastrectomy and represents the major cause of postoperative death, with a mortality rate of up to 50%. However, treatment remains challenging and controversial. We report here the case of a patient whose intrathoracic EJAL was successfully treated with computer tomography (CT)-guided negative pressure drainage treatment.

Albumin-Based LL37 Peptide Nanoparticles as a Sustained Release System against Lung Infection.

(PA) has emerged as a pressing challenge to pulmonary infection and lung damage. The LL37 peptide is an efficient antimicrobial agent against PA strains, but its application is limited because of fast clearance , biosafety concerns, and low bioavailability. Thus, an albumin-based nanodrug delivery system with reduction sensitivity was developed by forming intermolecular disulfide bonds to increase LL37 performance against PA.

TGF-β in pancreatic cancer initiation and progression: two sides of the same coin.

Pancreatic cancer is highly lethal malignant tumor with characterised rapid progression, invasiveness and resistance to radiochemotherapy. Transforming growth factor-β (TGF-β) signaling plays a dual role in both pro-tumorigenic and tumor suppressive of pancreatic cancer, depending on tumor stage and microenvironment. TGF-β signaling components alteration are common in pancreatic cancer, and its leading role in tumor formation and metastases has received increased attention.

Violet/blue chrysanthemums--metabolic engineering of the anthocyanin biosynthetic pathway results in novel petal colors.

Chrysanthemums (Chrysanthemum×morifolium Ramat.) are an important cut-flower and potted plant crop in the horticultural industry world wide. Chrysanthemums express the flavonoid 3'-hydroxylase (F3'H) gene and thus accumulate anthocyanins derived from cyanidin in their inflorescences which appear pink/red.

The association between polymorphisms in the leptin receptor gene and risk of breast cancer: a systematic review and pooled analysis.

Many epidemiological studies have found that leptin correlates to body fat extent and breast cancer. Leptin exerts its physiological action through the leptin receptor (LEPR). However, published data on the association between LEPR alleles and breast cancer occurrence have led to in contradictory results.

Perifosine sensitizes curcumin-induced anti-colorectal cancer effects by targeting multiple signaling pathways both in vivo and in vitro.

Our study shows that coadministration of curcumin and an orally bioactive alkylphospholipid perifosine results in a significant increase in colorectal cancer cell apoptosis and a marked inhibition of cell growth both in vitro and in vivo. This novel combinatorial regimen leads to changes of multiple cell signaling pathways including inactivation of Akt and nuclear factor-κB as well as activation of c-Jun N-terminal kinases and endoplasmic reticulum stress. Further, perifosine and curcumin synergistically increase intracellular level of reactive oxygen species and ceramide, and downregulate the expression of cyclin D1 and Bcl-2 in colorectal cancer cells.

Current treatment of rectovaginal fistula in Crohn's disease.

Rectovaginal fistula (RVF) continues to be the most difficult perianal manifestation of Crohn's disease to treat. This devastating and disabling complication has a significant impact on patients' quality of life and presents unique management challenges. Current therapeutic approaches include many medical therapeutics and surgical treatments with a wide range of success rates reported.

Activation of AMP-activated protein kinase contributes to doxorubicin-induced cell death and apoptosis in cultured myocardial H9c2 cells.

Despite its potent antitumor effect, clinical use of Doxorubicin is limited because of serious side effects including myocardial toxicity. Understanding the cellular mechanism involved in this process in a better manner is beneficial for optimizing Doxorubicin treatment. In the current study, the authors focus on the AMP-activated protein kinase (AMPK) in the said process.

Association between mitogen-activated protein kinase kinase kinase 1 rs889312 polymorphism and breast cancer risk: evidence from 59,977 subjects.

Published data on the association between mitogen-activated protein kinase kinase kinase 1 (MAP3K1) gene rs889312 polymorphism and breast cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Crude ORs with 95% CIs were used to assess the strength of association between them.

Association between polymorphisms of trinucleotide repeat containing 9 gene and breast cancer risk: evidence from 62,005 subjects.

Trinucleotide repeat containing 9 (TNRC9) is a gene located at chromosome 16q12. Although of an uncertain function, it is a newly described risk factor for breast cancer. It contains a putative high-mobility group box motif, suggesting its possible role as transcription factor; it has been implicated in breast cancer metastasis.

Association between polymorphisms of the ataxia telangiectasia mutated gene and breast cancer risk: evidence from the current studies.

Epidemiological studies have evaluated the association between ataxia telangiectasia mutated (ATM) gene polymorphisms and breast cancer risk. However, published data are still inconclusive.
