Retinoic acid receptor α (RARα) plays important roles in the progression of several cancers such as leukemia, breast cancer, and lung cancer. In this study, we demonstrated that RARα protein was frequently overexpressed in human CRC specimens and CRC cell lines. RARα knockdown decreased cell survival, proliferation, and colony formation in vitro and tumorigenic potential in nude mice. Specifically, RARα knockdown inhibited cell cycle progression at G1 phase through upregulation of cell cycle inhibitor p21, and downregulation of cyclinD1...

In this study, we present a broadband nano-photodetector based on single-layer graphene (SLG)-carbon nanotube thin film (CNTF) Schottky junction. It was found that the as-fabricated device exhibited obvious sensitivity to a wide range of illumination, with peak sensitivity at 600 and 920 nm. In addition, the SLG-CNTF device had a fast response speed (τr = 68 μs, τf = 78 μs) and good reproducibility in a wide range of switching frequencies (50-5400 Hz). The on-off ratio, responsivity, and detectivity of the device were estimated to be 1 × 10(2), 209 mAW(-1) and 4...

BACKGROUND: Denying parents access to their infant in the Neonatal Intensive Care Unit (NICU) is a standard practice in most hospitals across China. Visitation is not usually permitted or may be strictly limited, and NICU care for most neonates is provided by health-care professionals with little participation of the parents. An exception to this rule is the level 2 "Room-In" ward in Qilu Children's Hospital, Shandong University, where parents have 24-hour access to their infants and participate in providing care...

DNA vaccines had been widely used in animal models against various viral infections, while it was not so convincing for many infectious diseases especially bacterial disease in aquaculture. Interleukin-8(IL-8) as one of the CXC chemokines, its immunological role and adjuvant potential which had been proved in mammals were rarely reported in fish species. In this study, recombination plasmid pcDNA3.1/IL-8(pcIL-8) was conducted and the capacity of IL-8 as molecular adjuvant was explored from several aspects by co-injecting with a DNA vaccine encoding α-enolase(pcENO) against Streptococcus iniae infection in channel catfish...

: Mitochondria play a variety of functional roles in cortical neurons, from metabolic support and neuroprotection to the release of cytokines that trigger apoptosis. In dendrites, mitochondrial structure is closely linked to their function, and fragmentation (fission) of the normally elongated mitochondria indicates loss of their function under such pathological conditions as stroke and brain trauma. Using in vivo two-photon microscopy in mouse brain, we quantified mitochondrial fragmentation in a full spectrum of cortical injuries ranging from severe to mild...

BACKGROUND: Small intestinal neuroendocrine tumors (SI-NETs) are uncommon tumors with an annual incidence of about 1 per 100,000. Usually, SI-NETs have a slow progression, and patients often present with generalized disease. Many patients do well, and the disease has a relatively favorable 5-year survival rate. Some SI-NETs, however, have a more negative prognosis. This study aimed to establish prognostic factors for death identifiable at primary surgery. METHODS: A nested case-control study investigated 1150 patients from the cohort of all patients with a diagnosis of SI-NETs in Sweden between 1961 and 2001...

Renal involvement occurs in up to 60% of patients with systemic lupus erythematosus (SLE) and signifies a poor prognosis. The class of lupus nephritis (LN), determined on renal biopsy evaluation, guides the therapeutic management and has prognostic connotations. Our aim is to determine the clinicolaboratory features and histopathological patterns of LN at presentation in our local (South Indian) population. The study was conducted in a tertiary care hospital in South India between 2009 and 2014 on SLE patients with clinical evidence of LN...

OBJECTIVE: New-onset postpartum preeclampsia is a poorly defined condition that accounts for a significant percentage of eclampsia cases. It is unclear whether new-onset postpartum preeclampsia is a different disorder from or belongs to the same spectrum of classic antepartum preeclampsia. The objective of this study was to compare the clinical presentation and pregnancy outcomes of antepartum preeclampsia and new-onset postpartum preeclampsia. METHODS: A retrospective study including 92 patients with antepartum preeclampsia and 92 patients with new-onset postpartum preeclampsia was performed...

Expression of CD30 in blastoid cutaneous infiltrates typically signifies a CD30 lymphoproliferative disorder, often requiring minimal immunohistochemical workup, if clinically consonant. However, myeloid and other hematologic malignancies often express CD30. We retrospectively examined the prevalence of CD30 expression in 41 patients (median age 59) and 55 biopsies with the diagnosis of leukemia cutis (LC) to determine whether an extensive immunohistochemical workup is warranted in all large, round cell CD30 cutaneous infiltrates...

Ovarian carcinoma is initially sensitive to platinum-based therapy, but become resistant over time. The study of cancer sensitizing substance is therefore the major challenge for a number of scientific groups. Our experiments were carried out on human ovarian adenocarcinoma A2780cis cells resistant to cisplatin and their response to 2-(4'fluoro-phenylamino)-4H-1,3-thiazine[6,5-b]indole (thiazine[6,5-b]indole) and/or heat shock protein (Hsp) 90 inhibitor 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) using proliferation assay, cell cycle analysis and monitoring of apoptosis were examined...

BACKGROUND: The recognition of RV overpressure is critical to human life, as this may signify morbidity and mortality. Right ventricle (RV) dysfunction is understood to have an impact on the performance of the left ventricle (LV), but the mechanisms remain poorly understood. It is understood that ventricular compliance has the ability to affect cardiac performance. In this study, a bi-ventricular model of the rat heart was used in preference to other, single-ventricle models. Finite element analysis (FEA) of the bi-ventricular model provides important information on the function of the healthy heart...

Repeated exposures to social exclusion, through a process of sensitization, may result in larger responses to experiences of social stress. The current study tested the hypothesis that healthy Moroccan-Dutch men respond stronger to social stress than Dutch controls 1) in daily life, and 2) in an experimental set-up. A general population sample of 50 Moroccan-Dutch and 50 Dutch young adult males were tested with 1) the Experience Sampling Method, a structured diary technique, assessing reactivity to social stress in daily life, and 2) an experimental exposure to social peer evaluation...

Aging is a complex biological process that leads to several physiological changes. Among these changes, the most striking are those involving the innate and adaptive parts of the immune system. Furthermore, these changes are associated with a low-grade inflammation called inflamm-aging, which is the result of several lifelong antigenic stimulations, including chronic viral infections such as cytomegalovirus. Immunosenescence, concomitantly with inflamm-aging, is considered as the leading cause of age-related diseases including cardiovascular, neurodegenerative and metabolic diseases, and cancer...

Previous research has agreed that meaning-making is a key element in the promotion of patients' well-being during and after a traumatic event such as cancer. In this paper, we focus on an underestimated key element related to the crisis/rupture of this meaning-making process with respect to the time perspective. We consider 40 narratives of breast cancer patients at different times of treatment, undergoing chemotherapy and biological therapy. We collected data through writing technique. We performed an interpretative thematic analysis of the data and highlighted specific ways to signify time during the different treatment phases...

BACKGROUND: In the United States, over 1,650,000 new cases of cancer are being diagnosed yearly with almost 50 % of them being the top five bone-seeking cancers. Since cancer risk increases with age, this suggests that orthopedic oncology services may be a strain on the Medicare system. The femur is the most common site of long bone metastases. Prophylactic fixation techniques prevent pathologic fractures, reduce morbidities, and enhance the quality of life of patients with femoral metastases...
