Deletion or mutation of the gene encoding the deubiquitinating enzyme CYLD is a common genomic aberration in multiple myeloma (MM). However, the functional consequence of CYLD loss and the mechanism underlying its putative role as a tumor suppressor gene in the pathogenesis of MM has not been established. Here, we show that CYLD expression is highly variable in myeloma cell lines and primary MMs and that low CYLD expression is associated with disease progression from monoclonal gammopathy of undetermined significance to MM, and with poor overall and progression free-survival of MM patients...

The aim of this study was to examine the cytotoxic and genotoxic potential of a hydroethanolic extract of Schefflera vinosa (SV), a plant with schistosomicidal activity, as well as its influence on DNA damage induced by different mutagens, methyl methane sulfonate (MMS) and hydrogen peroxide (H2O2), in V79 cells and Swiss mice. Schefflera vinosa extract produced cytotoxicity at concentrations of 312.5 µg/ml or higher using the XTT cell proliferation assay kit. Treatment of V79 cell cultures with the highest SV concentration tested (150 µg/ml) significantly increased the frequency of micronuclei (MN) compared to controls...

The knowledge of HLA characteristics of a patient's population helps to predict the probability of finding a MUD. The study included transplanted 170 patients for whom a search for a MUD in BMDW was performed and a sample of 4000 volunteer unrelated donors from the Croatian Bone Marrow Donor Registry (CBMDR). Patients and their MUDs were typed for HLA-A, -B, -C, -DRB1, and -DQB1 loci using PCR-SSO and PCR-SSP methods while donors were typed for HLA-A, -B, -C and -DRB1 loci using the PCR-SSO method. A comparison of allele frequencies at tested HLA loci between patients and donors from CBMDR did not reveal significant differences...

BACKGROUND: Basal cell carcinoma (BCC) is the most common malignancy in the United States. Most BCCs occur on cutaneous surfaces, but rare cases on the mucosal lip have also been documented. Because only a small number of mucosal BCC (mBCC) cases have been reported, data on their clinical characteristics and management are limited. OBJECTIVE: To perform an updated literature review of the management of mBCCs on the lip. METHODS: A comprehensive literature review was conducted through a search of the PubMed database with the key phrases "mucosal basal cell carcinoma," "basal cell carcinoma mucosa," and "basal cell carcinoma lip mucosa...

The primary constraints for efficient oral delivery of anticancer drugs include the efflux pump function of the multidrug transporter P-glycoprotein (P-gp) for anticancer drugs and the barriers to drug absorption in gastrointestinal (GI) tract. To improve bypassing P-gp drug efflux pumps and oral bioavailability of doxorubicin hydrochloride (DOX), Multilayer micro-dispersing system (MMS) was constructed by co-immobilization of DOX loaded chitosan/carboxymethyl chitosan nanogels (DOX:CS/CMCS-NGs), along with quercetin (Qu) in the core of multilayer sodium alginate beads (DOX:NGs/Qu-M-ALG-Beads)...

Spermatogenesis is threatened by DNA alkylating agents, one major category of DNA damaging agents. Currently, little is known about the alterations in transcriptome profiling of the mouse spermatogenic cells in response to DNA alkylation at distinct stages of spermatogenesis. In this study, RNA sequencing (RNA-seq) was performed in pachytene spermatocytes (PS) and round spermatids (RS) at 0 or 30min following Methyl Methanesulfonate (MMS) treatment and with untreated controls. A large number of differentially expressed genes (DEGs) were identified by comparison of the three groups in PS and RS, respectively...

Malignant mesothelioma (MM) is an aggressive malignancy of the pleura and other serosal membranes originating from mesothelial cells that, despite decades of research, continues to have limited therapeutic options and is associated with a poor prognosis. Areas covered: MMs induce a strong inflammatory response that is also associated with neoangiogenesis and activation of proangiogenic factors. Given this, several anti-angiogenic agents have been trialled in a variety of malignancies including mesothelioma...

The E. coli dnaN-encoded β sliding clamp protein plays a pivotal role in managing the actions on DNA of the 5 bacterial DNA polymerases, proteins involved in mismatch repair, as well as several additional proteins involved in DNA replication. Results of in vitro experiments indicate that the loading of β clamp onto DNA relies on both the DnaX clamp loader complex as well as several discrete sliding clamp-DNA interactions. However, the importance of these DNA interactions to E. coli viability, as well as the ability of the β clamp to support the actions of its numerous partner proteins, have not yet been examined...

OBJECTIVE: Anomia is the second most common disorder after episodic memory loss in patients with Alzheimer's disease. Our objective was to develop a speech therapy protocol for patients with Alzheimer's disease (Mini-Mental State Examination or MMSE≥15) and suffering from a lack of words, in order to improve access to words. MATERIAL/PATIENTS AND METHODS: We stimulated the three stages in the men: - stimulation of lexical selection involved working on the multiple meanings of a word, searching for the relevant and specific features of a word in order to make a guess, and bringing to mind a target word from specific features; - stimulation of morphological encoding involved extracting the meaning of a morpheme by comparing two words, one of which is derived from the other, and then identifying the meaning of an affix by slipping it into a sentence; - phonological encoding was stimulated by the isolation of the initial two-syllable words and merging them to form a third word...

New Magnetospheric Multiscale (MMS) observations of small-scale (~7 ion inertial length radius) flux transfer events (FTEs) at the dayside magnetopause are reported. The 10 km MMS tetrahedron size enables their structure and properties to be calculated using a variety of multispacecraft techniques, allowing them to be identified as flux ropes, whose flux content is small (~22 kWb). The current density, calculated using plasma and magnetic field measurements independently, is found to be filamentary. Intercomparison of the plasma moments with electric and magnetic field measurements reveals structured non-frozen-in ion behavior...
