A chronic wound in diabetic patients is usually characterized by poor angiogenesis and delayed wound closure. The exploration of efficient strategy to significantly improve angiogenesis in the diabetic wound bed and thereby accelerate wound healing is still a significant challenge. Herein, we reported a kind of aligned porous poly (L-lactic acid) (PLLA) electrospun fibrous membranes containing dimethyloxalylglycine (DMOG)-loaded mesoporous silica nanoparticles (DS) for diabetic wound healing. The PLLA electrospun fibers aligned in a single direction and there were ellipse-shaped nano-pores in situ generated onto the surface of fibers, while the DS were well distributed in the fibers and the DMOG as well as Si ion could be controlled released from the nanopores on the fibers...

Abnormal signaling pathways mediated by N-methyl-d-aspartate receptors (NMDARs) have been implicated in the pathogenesis of various CNS disorders and have been long considered as promising points of therapeutic intervention. However, few efforts have been previously described concerning evaluation of therapeutic modulators of NMDARs and their downstream pathways in human neurons with endogenous expression of NMDARs. In the present study, we assessed expression, functionality, and subunit composition of endogenous NMDARs in human induced pluripotent stem cell (hiPSC)-derived cortical neurons (iCell Neurons and iCell GlutaNeurons)...

Lipoprotein lipase (LPL) is a rate-limiting enzyme that catalyzes hydrolysis of the triglyceride (TG) core of circulating TG-rich lipoproteins including chylomicrons (CM), low-density lipoproteins (LDL) and very low-density lipoproteins (VLDL). A variety of parenchymal cells can synthesize and secrete LPL. Recent studies have demonstrated that complicated processes are involved in LPL biosynthesis, secretion and transport. The enzyme activity of LPL is regulated by many factors, such as apolipoproteins, angiopoietins, hormones and miRNAs...

BACKGROUND: Aggressive hepatectomy with venous resection has a higher risk of postoperative liver failure (POLF) than hepatectomy without venous reconstruction; however, venous reconstruction is technically demanding. We performed a novel two-stage hepatectomy (TSH) without venous reconstruction in a patient with bilobar multiple colorectal liver metastases located near the caval confluence, waiting for the development of intrahepatic venous collaterals between procedures. CASE PRESENTATION: A 60-year-old man was referred to our hospital with sigmoid colon cancer accompanied by intraabdominal abscess and two synchronous liver metastases...

Sertoli cells, as the unique somatic cells within the seminiferous tubules, play essential roles in regulating normal spermatogenesis. In addition, recent studies have demonstrated that Sertoli cells could have significant applications in regenerative medicine due to their great plasticity. However, the roles of genes in controlling the fate determinations of human Sertoli cells remain largely unknown. Silencing genes of human Sertoli cells utilizing small interfering RNAs (siRNAs) is an important method to explore their functions and mechanisms in human Sertoli cells...

A 15-year old male patient presented to us with dyspnoea for four days. He had a history of fever, pseudo-membranous tonsillitis and cervical adenopathy twenty-five days prior to the presentation. On examination and laboratory investigations, he had features suggestive of myocarditis with biventricular failure. There was no reliable history of immunisation and he had a positive history of contact. He was planned for anti-diphtheria toxin but before the anti-toxin could be initiated, the patient succumbed to refractory cardiogenic shock...

Identifying noncoding risk variants remains a challenging task. Because noncoding variants exert their effects in the context of a gene regulatory network (GRN), we hypothesize that explicit use of disease-relevant GRNs can significantly improve the inference accuracy of noncoding risk variants. We describe Annotation of Regulatory Variants using Integrated Networks (ARVIN), a general computational framework for predicting causal noncoding variants. It employs a set of novel regulatory network-based features, combined with sequence-based features to infer noncoding risk variants...

Integrin αV (ITGAV) gene expression is often dysregulated in cancers especially in hepatocellular carcinoma (HCC); however, the mechanism of regulation is poorly understood. Here, it is demonstrated that sulfatide activated integrin αV gene transcription, through histone H3K9/14 acetylation at the promoter, and high integrin αV expression are closely associated with poor prognosis. To elucidate the mechanism of regulation of acetylation, sulfatide-bound proteins were screened by mass spectrometry (MS), and BRD1 (bromodomain containing protein 1) was identified as an interacting protein that also co-localized with sulfatide in HCC cells...

The adjustment of metabolic patterns is fundamental to fungal biology and plays vital roles in adaption to diverse ecological challenges. Nematode trapping fungi can switch lifestyles from saprophytic to pathogenic by developing specific trapping devices induced by nematodes to infect their prey as a response to nutrient depletion in nature. However, the chemical identity of the specific fungal metabolites used during the switch remains poorly understood. We hypothesized that these important signal molecules might be volatile in nature...

We describe a case of polymicrobial bacterial pericarditis with Klebsiella pneumoniae and Proteus mirabilis , caused by pericardial penetration of the tip of the catheter of a laparoscopic adjustable gastric band (LAGB). The patient developed a cardiac tamponade, and subsequently emergency pericardiocentesis was performed. Analysis of earlier CT scans showed that the tip of the catheter had migrated through the liver and through the diaphragm into the pericardium, and was in contact with the myocardium. After stabilisation he was operated to remove the LAGB...
