Cytoreductive surgery (CRS) and HIPEC results in a median disease-free survival (DFS) of 12-15 months, overall survival (OS) of 23-63 months, and cure in around 15% of patients with colorectal peritoneal metastases (CPM). The wide variation in OS may largely be attributed to different criteria for patient selection employed by different investigators. To evaluate outcomes of CRS and HIPEC for CPM in patients enrolled in the Indian HIPEC registry. A retrospective analysis of patients enrolled in the registry since its inception in March 2016 was performed...

Stable-isotope probing is widely used to study the function of microbial taxa in their natural environment, but sorting of isotopically labelled microbial cells from complex samples for subsequent genomic analysis or cultivation is still in its early infancy. Here, we introduce an optofluidic platform for automated sorting of stable-isotope-probing-labelled microbial cells, combining microfluidics, optical tweezing and Raman microspectroscopy, which yields live cells suitable for subsequent single-cell genomics, mini-metagenomics or cultivation...

There are many downstream targets of mitogen-activated protein kinase (MAPK) signalling that are involved in neuronal development, cellular differentiation, cell migration, cancer, cardiovascular dysfunction and inflammation via their functions in promoting apoptosis and cell motility and regulating various cytokines. It has been reported that cyclic AMP response element-binding protein (CREB) is phosphorylated and activated by cyclic AMP signalling and calcium/calmodulin kinase. Recent evidence also points to CREB phosphorylation by the MAPK signalling pathway...

This study investigated the effect of different specific surface area micronized zinc oxide (ZnO) on growth performance, zinc (Zn) tissue content, jejunal morphology, jejunal antioxidative status, and intestinal mucosa barrier-related gene expression in meat ducks. A total of 480 one-day-old Cherry Valley ducks were randomly divided into 4 dietary treatments, which each had 12 replicates; therefore, each replicate consisted of 10 ducks. Experimental diets included the basal diet supplemented with ZnSO4 (control group) and 3 different treatments of specific surface area micronized ZnO, in which the specific surface area was either 11...

Cathelicidins, a class of antimicrobial peptides, have been widely studied for their antimicrobial role in innate immune responses during infection and inflammation. At sub-antimicrobial concentrations, various cathelicidins from different species have been reported to exert chemotactic activity on neutrophils, monocytes, dendritic cells and T-cells, and also enhance angiogenesis and wound healing. To date, the role of the pig cathelicidin, protegrin-1 (PG-1), in immune modulation and tissue repair in the intestinal tract has not been investigated...

Long-term survival rates for pediatric patients with cancer have significantly improved, but novel approaches are desired for those with refractory/relapsed solid tumors. Recently, programed cell death-1/programed cell death-ligand-1 blockade has emerged as an effective option for many intractable cancers. However, not all patients show objective response to such therapy. On the other hand, several other checkpoint pathways, including Herpes virus entry mediator (HVEM)/B- and T-lymphocyte attenuator (BTLA), galectin-9 (GAL9)/T-cell immunoglobulin and mucin domain-3 (TIM3), and major histocompatibility complex class II (MHC-II)/lymphocyte activation gene-3 (LAG3), also regulate immune responses in the tumor microenvironment and may be alternative targets for novel immune therapies...

OBJECTIVE: Macrophage-mediated inflammation plays a significant role in the development and progression of diabetic nephropathy (DN). However, the underlying mechanisms remain unclear. Studies suggest that T cell immunoglobulin domain and mucin domain-3 (Tim-3) has complicated roles in regulating macrophage activation, but its roles in the progression of DN are still completely unknown. METHODS: We downregulated Tim-3 expression in kidney (intrarenal injection of Tim-3 shRNA expressing lentivirus or global Tim-3 knockout mice) and induced DN by streptozotocin (STZ)...

Human salivary gland (SG) branching morphogenesis is an intricate mechanism divided into stages, prebud, initial bud, pseudoglandular, canalicular, and terminal bud, to form the final lobular structure of the organ. The coordination of molecular cascades, including cell proliferation and apoptosis, are fundamental to this process. The intrinsic apoptosis pathway appears to be important in the early phases of ductal cavitation and luminisation; however, the role of the extrinsic apoptosis pathway has still to be determined...

Exposure to diesel exhaust particles (DEPs) is known to cause serious health problems, owing to a steady increase in the number of diesel vehicles worldwide. DEPs comprise approximately 90% particle mass existing in the fine size range (≤2.5 μm) and are mainly absorbed in the respiratory tract. However, limited information is available on the effects of DEP exposure on the respiratory tract in humans. Here, we investigated the effect and signaling pathways of DEPs on the expression of mucin, especially MUC5AC and MUC5B, in human airway epithelial cells by reverse-transcriptase polymerase chain reaction (PCR), real-time PCR, enzyme-linked immunosorbent assay, western blotting, and immunofluorescence staining...

Developing a biomaterial that promotes regeneration of both respiratory epithelium (RE) and olfactory neuroepithelium (ON) improves the surgical outcome of endoscopic sinus surgery. Although chitosan (CS) inhibits mucociliary differentiation of RE, it has been reported to regenerate ON. In addition, hyaluronic acid (HA) has been demonstrated to promote regeneration of RE. Whether the composite CS + HA would simultaneously benefit RE and ON remains unexplored. Human nasal respiratory epithelial cells (RECs) and olfactory neuroepithelial cells (ONCs) are respectively obtained from the RE and the ON...

Colorectal cancer (CRC) with the V600E mutation of B-Raf proto-oncogene serine/threonine kinase (BRAFV600E ) mutation is insensitive to chemotherapy and is indicative of a poor patient prognosis. Although BRAF inhibitors have a marked effect on malignant melanoma harboring the BRAFV600E mutation, they have a limited effect on patients with CRC with the same BRAF mutation. A previous study identified a novel gene, monopolar spindle protein kinase 1 (Mps1), a downstream target of BRAFV600E only, rather than of wild-type BRAF as well, which contributes to tumorigenesis in melanoma...

A fluorometric method is described for the determination of the tumor biomarker mucin 1 (MUC1). It is based on signal amplification of the hybridization chain reaction (HCR), and the interaction between a luminescent ruthenium(II) complex and CdZnTeS quantum dots (QDs). If MUC1 bind to the biotin-labeled aptamer, it will initiate HCR with hairpins H1 and H2 to form a long-range dsDNA. The long nucleic acid chains are then linked on the surface of streptavidin-modified magnetic microparticles (MMPs) through streptavidin-biotin interaction...

Ciliated muconodular papillary tumors (CMPTs) of the lung are rare, likely benign neoplastic lesions. Here we describe a case of a CMPT, focusing on its cytologic features, which to our knowledge have not been reported previously. Owing to dull back pain, a 69-year-old male non-smoker underwent CT, which revealed a 1.3 × 1.3-cm solid nodule in the peripheral field of the left lower lung lobe. A wedge resection of the nodule was performed, with the provisional diagnosis being primary lung cancer. Macroscopic examination of a resected specimen showed a 1...

Recent data suggest that tumor laterality and mucinous histology may be clinically relevant. We investigated how both variables impact on the prognosis and the response to therapies in a large population-based cohort of cancer patients. Incidence data, clinical and pathological features, and outcome were systematically collected from the Tumor Registry of Parma over the years 2004-2009. Survival data were modeled by multivariable analysis. 1358 patients affected by stage I-IV colon cancer were considered; 661 (49%) had right-sided and 697 (51%) left-sided tumors...
