Molecular and cellular mechanisms of PDAC progression based on RETN-CAP1-mediated macrophage-fibroblast crosstalk: Action of ITGB5 and ITGB1 recombinant proteins.

Pancreatic ductal adenocarcinoma (PDAC) has a very poor prognosis, and the main objective of this study was to reveal the specific mechanism of action of TN-CAP1-mediated macrophage-fibroblast crossinulation in the progression of PDAC, and to evaluate the function and potential therapeutic value of ITGB5 and ITGB1 recombinant proteins in this process. The expression of TN-CAP1 in tumor tissues of PDAC patients was analyzed by immunohistochemistry and compared with normal pancreatic tissues. The co-culture system of macrophages and fibroblasts was constructed using in vitro cell culture model.

Primary duodenal papilla lymphoma producing obstructive jaundice: a case report.

Background: Obstructive jaundice caused by primary duodenal lymphoma is a rare disease.

Case Presentation: We reported a 59-year-old man who underwent endoscopic ultrasonography for obstructive jaundice and found a duodenal papilla tumor. Light microscopy revealed a non-Hodgkin's lymphoma.

The thalamus and its subnuclei-a gateway to obsessive-compulsive disorder.

Larger thalamic volume has been found in children with obsessive-compulsive disorder (OCD) and children with clinical-level symptoms within the general population. Particular thalamic subregions may drive these differences. The ENIGMA-OCD working group conducted mega- and meta-analyses to study thalamic subregional volume in OCD across the lifespan.

A comprehensive comparison and analysis of soil screening values derived and used in China and the UK.

China and the UK use different risk-based approaches to derive soil screening or guideline values (SSVs; SGVs) for contaminants. Here we compare the approaches and the derived values for 6 illustrative contaminants. China's SSVs are derived using an approach developed in the US as follows: for carcinogens, acceptable level of risk (ACR) is set at 10 and the SSVs calculated as 10 divided by the soil exposure and toxicity data; for non-carcinogens, the hazard quotient is 1 and the SSV is calculated as 1 divided by the soil exposure and toxicity data.

Oncogenicity of lncRNA FOXD2-AS1 and its molecular mechanisms in human cancers.

Objectives: Long non-coding RNAs (lncRNAs) are a group of noncoding RNAs with length larger than 200 nucleotides. LncRNAs have limited or no protein-coding capacity because of lack of obvious open reading frame. An increasing number of researches have shown that lncRNAs participate in the complex regulation network of cancer and play an important role in tumourigenesis and progression such as proliferation, migration and invasion.

LncRNA HOXA-AS2 and its molecular mechanisms in human cancer.

Long non-coding RNAs (lncRNAs), a novel class of noncoding RNAs, are commonly defined as RNA molecules more than 200 nucleotides in length. Emerging research indicated that lncRNA played a vital role in human tumorigenesis and progression by serving as tumor oncogenes or suppressors. LncRNA has been shown to get involved in participate various biological processes, such as cell growth, anti-apoptosis, migration and invasion.

Diagnosis and management of primary hepatic pregnancy: literature review of 31 cases.

Purpose: To summarize the appropriate diagnostic methods and therapeutic options for primary hepatic pregnancy (PHP).

Methods: Literature searches were performed in Pubmed, Web of Science, Cochrane Library and Embase databases (1956-2017), using the following search terms: primary hepatic pregnancy, hepatic pregnancy, liver pregnancy, hepatic ectopic pregnancy and intrahepatic pregnancy. Further literature was confirmed through cross-referencing.

Psychotomimetic effects of different doses of MK-801 and the underlying mechanisms in a selective memory impairment model.

Although N-methyl-d-aspartate receptor antagonists-induced hypoglutamate rodent models are the most well-established models for preclinical studies of schizophrenia-related deficits, they also evoke a wide spectrum of psychotomimetic side effects. It is significant to increase the specificity of hypoglutamate rodent models. In this study, the recognition memory was evaluated in rats by object recognition test (ORT), sensorimotor gating was evaluated by prepulse inhibition of the startle reflex (PPI), and locomotor activity was measured using open field test.

Three dysconnectivity patterns in treatment-resistant schizophrenia patients and their unaffected siblings.

Unlabelled: Among individuals diagnosed with schizophrenia, approximately 20%-33% are recognized as treatment-resistant schizophrenia (TRS) patients. These TRS patients suffer more severely from the disease but struggle to benefit from existing antipsychotic treatments. A few recent studies suggested that schizophrenia may be caused by impaired synaptic plasticity that manifests as functional dysconnectivity in the brain, however, few of those studies focused on the functional connectivity changes in the brains of TRS groups.

Promoter variant rs2301228 on the neural cell adhesion molecule 1 gene confers risk of schizophrenia in Han Chinese.

Background: Schizophrenia is recognized as a disorder of the brain and neuronal connectivity. The neural cell adhesion molecule 1 (NCAM1) gene plays a crucial role in regulating neuronal connectivity.

Methods: We conducted a two-stage association analysis on 17 NCAM1 SNPs in two independent Han Chinese schizophrenia case-control cohorts (discovery sample from Hunan Province: 986 patients and 1040 normal controls; replication sample from Yunnan Province: 564 cases and 547 healthy controls).

White matter microstructural abnormalities in patients with late-onset schizophrenia identified by a voxel-based diffusion tensor imaging.

Reduced fractional anisotropy (FA) has been previously found in diffusion tensor imaging (DTI) studies of white matter in schizophrenic patients. However, there are no reports in the literature that address FA alterations in late-onset schizophrenia (LOS). The current study measured FA in whole white matter and subsequently analyzed its association with psychotic symptoms in LOS.
