Efficacy of a smartphone application assisting home-based rehabilitation and symptom management for patients with lung cancer undergoing video-assisted thoracoscopic lobectomy: a prospective, single-blinded, randomised control trial (POPPER study).

Background: Video-assisted thoracoscopic (VATS) lobectomy can affect patients' pulmonary function and quality of life significantly. No optimal protocol combining patient-reported outcome-based symptom management and post-discharge rehabilitation programme has yet been established. This study aimed to assess the efficacy of a novel smartphone app designed for home-based symptom management and rehabilitation.

A cell hybridization-based method of generating recombinant rabbit monoclonal antibodies for detecting cytokines.

Recombinant rabbit monoclonal antibodies (rabbit rAbs) have shown promise in various biomedical fields. However, it is challenging and costly to generate rabbit rAbs using traditional techniques. Here we describe a convenient and cost-effective method.

Application of sodium bicarbonate in extraction and determination of synthetic colorant in processed grain products.

Unlabelled: As the only standard of its kind, GB5009.35-2016 provides the determination of water-soluble synthetic colorants in processed grain products with high starch content for the purpose of food safety risk monitoring. However, it's only applicable to candy products and liquid foods as beverages, but not solid grain products.

Aqua-bis-(4-chloro-benzoato)-κ(2) O,O';κO-bis-(pyridine-κN)cobalt(II).

In the title compound, [Co(C7H4ClO2)2(C5H5N)2(H2O)], the Co(II) atom is six-coordinated by three O atoms from a bidentate and a monodentate 4-chloro-benzoate ligand, two N atoms from two pyridine ligands and a water O atom, giving a distorted octa-hedral geometry. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds and π-π interactions between the benzene rings [centroid-centroid distance = 3.8924 (17) Å] into a chain along [010].

Genomic and clinical analysis of fusion gene amplification in rhabdomyosarcoma: a report from the Children's Oncology Group.

Alveolar rhabdomyosarcoma (RMS) is an aggressive pediatric cancer of the myogenic lineage with frequent chromosomal translocations involving the PAX3 or PAX7 and FOXO1 genes. Based on previous studies indicating that the fusion genes are amplified in a subset of these cancers, we conducted a comprehensive molecular and clinical investigation of these amplification events. Using oligonucleotide arrays to localize amplicons, we found that the minimal 1p36 amplicon measured 0.

Genomic and clinical analysis of amplification of the 13q31 chromosomal region in alveolar rhabdomyosarcoma: a report from the Children's Oncology Group.

Purpose: This study determined the molecular characteristics and clinical significance of amplification of the 13q31 chromosomal region in alveolar rhabdomyosarcoma (ARMS), an aggressive pediatric cancer with frequent PAX3-FOXO1 and PAX7-FOXO1 gene fusions.

Experimental Design: The 13q31 amplicon was localized in an initial panel of ARMS cases using oligonucleotide arrays. A fluorescence in situ hybridization assay for this localized region was designed, and applied to more ARMS cases to determine the frequency and distribution of amplification.

High expression of the PAX3-FKHR oncoprotein is required to promote tumorigenesis of human myoblasts.

PAX3-FKHR is a fusion oncoprotein generated by the 2;13 chromosomal translocation in alveolar rhabdomyosarcoma (ARMS), a cancer associated with the skeletal muscle lineage. Previous studies determined that high-level PAX3-FKHR expression is a consistent feature in ARMS tumors. To investigate the relationship between expression and phenotype in human myogenic cells, PAX3-FKHR was introduced into immortalized human myoblasts to produce a low overall PAX3-FKHR expression level.

Identification of PAX3-FKHR-regulated genes differentially expressed between alveolar and embryonal rhabdomyosarcoma: focus on MYCN as a biologically relevant target.

Rhabdomyosarcoma is a family of myogenic soft tissue tumors subdivided into two main subtypes: alveolar (ARMS) and embryonal (ERMS). ARMS is characterized by a frequent 2;13 chromosomal translocation that creates a PAX3-FKHR fusion transcription factor. To identify downstream targets of PAX3-FKHR, we introduced an inducible form of PAX3-FKHR into human RD ERMS cells.

IgG antibodies to plasminogen and their relationship to IgG anti-beta(2)-glycoprotein 1 antibodies and thrombosis.

Reduced fibrinolytic activity has been described in primary antiphospholipid syndrome (PAPS) and may be responsible for thrombotic events. Some evidence supports a relationship between anti-plasminogen (PLG) antibodies, anti-beta(2)-glycoprotein 1 (beta(2)GP1) antibodies, and fibrinolysis, but their relationship is still unclear. The aim of study is to evaluate the association between IgG anti-beta(2)GP1 and IgG anti-PLG antibodies and thrombosis.

Virion-associated uracil DNA glycosylase-2 and apurinic/apyrimidinic endonuclease are involved in the degradation of APOBEC3G-edited nascent HIV-1 DNA.

Cellular cytidine deaminases APOBEC3 family is a group of potent inhibitors for many exogenous and endogenous retroviruses. It has been demonstrated that they induce G to A hypermutations in the nascent retroviral DNA, resulting from the cytosine (C) to uracil (U) conversions in minus-stranded viral DNA. In this report, we have demonstrated that the result of C to U conversion in minus-stranded DNA of human immunodeficiency virus type 1 (HIV-1) could trigger a degradation of nascent viral DNA mediated by uracil DNA glycosylases-2 (UNG2) and apurinic/apyrimidinic endonuclease (APE).

Inhibition of endogenous reverse transcription of human and nonhuman primate lentiviruses: potential for development of lentivirucides.

In the current study, we extended our previous works on natural endogenous reverse transcription (NERT) and further examined its potential as a virucide molecular target in sexual transmission of primate lentiviruses. HIV-1 and SIV virions were pretreated with select nucleoside (NRTIs) and nonnucleoside RT inhibitors (NNRTIs), either alone or in combination with NERT-stimulating substances. The effects of these antiretrovirals on virion inactivation were analyzed in human T cell lines and primary cell cultures.

Alpha interferon potently enhances the anti-human immunodeficiency virus type 1 activity of APOBEC3G in resting primary CD4 T cells.

The interferon (IFN) system, including various IFNs and IFN-inducible gene products, is well known for its potent innate immunity against wide-range viruses. Recently, a family of cytidine deaminases, functioning as another innate immunity against retroviral infection, has been identified. However, its regulation remains largely unknown.

Characterization of related impurities in megestrol acetate.

Three new compounds, 17alpha-acetoxy-2,6-dimethylpregna-1,4,6-triene-3,20-dione (1), 17alpha-acetoxy-2alpha,6-dimethylpregna-4,6-diene-3,20-dione (2), 17alpha-acetoxy-6alpha-methoxylmethylpregna-4-ene-3,20-dione (3), together with five known ones, 17alpha-acetoxy-6beta-hydroxyl-6alpha-methylpregna-4-ene-3,20-dione (4), 17alpha-acetoxy-6alpha-hydroxyl-6beta-methylpregna-4-ene-3,20-dione (5), 17alpha-acetoxy-pregna-4-ene-3,6,20-trione (6), 17alpha-acetoxy-pregna-4-ene-3,20-dione (7) and 17alpha-acetoxy-6-methylene-pregna-4-ene-3,20-dione (8), were isolated and identified from the residual mother liquor of megestrol acetate. Their structures were established by spectroscopic methods. These compounds seem to be minor impurities in production of the drug megestrol acetate.

Exogenous IL-7 induces Fas-mediated human neuronal apoptosis: potential effects during human immunodeficiency virus type 1 infection.

The use of exogenous cytokines is part of translational immune-antiretroviral approaches to induce immune reconstitution and possibly eliminate the persistence of human immunodeficiency virus type 1 (HIV-1) in virally suppressed infected individuals on highly active antiretroviral therapy (HAART). Recently, our laboratories demonstrated that interleukin-7 (IL-7) has significant efficiency in stimulating HIV-1 replication from proviral latency in CD4+ T lymphocytes of infected patients. The authors now investigated the possible role of IL-7 in HIV-1-associated dementia (HAD).

The cytidine deaminase CEM15 induces hypermutation in newly synthesized HIV-1 DNA.

High mutation frequency during reverse transcription has a principal role in the genetic variation of primate lentiviral populations. It is the main driving force for the generation of drug resistance and the escape from immune surveillance. G to A hypermutation is one of the characteristics of primate lentiviruses, as well as other retroviruses, during replication in vivo and in cell culture.
