Résumé :

This study aimed to develop and optimize polyvinyl alcohol (PVA)-based polymeric films containing resveratrol (RSV) and to evaluate their applicability as oral mucosal wound dressings. Given the dynamic and complex nature of the oral environment, physicochemical parameters such as elasticity, mucoadhesive strength, and the release profile of the RSV were systematically investigated. The therapeutic performance of pure resveratrol was compared with that of an extract derived from Reynoutria japonica. Films were fabricated using a solvent casting method and characterized in terms of thickness un

Résumé :

Abstract As 5G networks evolve to meet increasing demands for high-speed data, the integration of Frequency Range 1 (FR1) and Frequency Range 2 (FR2) bands has emerged as a key focus. While FR1 offers broad coverage, FR2 (mmWave) provides high capacity but faces challenges such as high propagation loss and susceptibility to blockage. Carrier Aggregation (CA) in 5G allows for the simultaneous utilization of multiple frequency bands, enhancing overall network capacity and performance by combining FR1 and FR2 resources. This study evaluates the effectiveness of CA in integrating FR1 and FR2 bands

Object. Diagnosing primary central nervous system lymphoma (PCNSL) may be difficult either because of a paucity of tumor cells in the brain biopsy specimens or a failure to demonstrate monoclonality on immunomorphological studies. Monoclonality can also be demonstrated by amplification of the rearranged immunoglobulin H genes by polymerase chain reaction (PCR) to the framework region (FR)3 and FR2 complementarity determining region (CDR)-III and CDR-II of these genes. The PCR method is feasible with formalin-fixed, paraffin-embedded biopsy material and has proven to be helpful in the diagnosis

Novel treatments in gastrointestinal stromal tumors (GISTs) are essential due to imatinib resistance and the modest results obtained with multi-target tyrosine kinase inhibitors. We investigated the possibility that the hydroalcoholic extract from the leaves of Arbutus unedo L. (AUN) could harbor novel chemotherapeutics. The bio-guided fractionation of AUN led to a subfraction, FR2-A, that affected the viability of both imatinib-sensitive and -resistant GIST cells. Cells treated with FR2-A were positive for Annexin V staining, a marker of apoptosis. A rapid PARP-1 downregulation was observed,

Abstract Two nuclear genes, Fr and Fr2, have been identified that restore pollen fertility to cytoplasmic male sterile (CMS) common bean (Phaseolus vulgaris L.) by apparently distinct mechanisms. Whereas Fr2 appears to suppress the expression of a male sterility associated mitochondrial sequence (designated pvs), Fr restores pollen fertility by causing the elimination of this unusual mitochondrial DNA-segment. To further investigate the mechanism of Fr action, Fr and Fr2 were cointroduced into the nucleus of a bean line containing the sterility inducing cytoplasm. When the effect of pvs was su

Résumé :

Fusarium wilt race 1, caused by the soilborne fungus Fusarium oxysporum Schlechtend.: Fr. f. sp. niveum (E.F. Sm.) W.C. Snyder & H.N. Hans (Fon), is a major disease of watermelon (Citrullus lanatus) in the United States and throughout the world. Although Fusarium wilt race 1 resistance has been incorporated into several watermelon cultivars, identification of additional genetic sources of resistance is crucial if a durable and sustainable level of resistance is to be continued over the years. We conducted a genetic mapping study to identify quantitative trait loci (QTLs) associated with re

Abstract Background: A somatic mutation rate of >2% of the immunoglobulin (IgH) heavy chain gene, in comparison to germline DNA, is a positive prognostic indicator in chronic lymphocytic leukemia (CLL). Genomic DNA is amplified using the Biomed-2 multiplex PCR primer set, sequenced in the reverse direction only using a 3′ JH primer, and compared to the germline sequence in VBase, a comprehensive directory of all human germline variable region sequences compiled from over a thousand published sequences. It is unknown whether forward sequencing using the multiplex 5′ Biomed-2 primers in a sin

Résumé :

This paper presents a 5G new radio (NR) FR2 beamforming system with an integrated transceiver module. A real-time operating module providing enhanced flexibility and capability has been proposed. The integrated RF beamforming system with an integrated transceiver module can be operated in 8Tx-8Rx mode configuration simultaneously. A series-fed structure 8 × 7 microstrip antenna array for compact size and improved directivity is employed in the RF beamforming module. The RF beamforming module incorporates a custom 28 GHz, eight-channel fully differential beamforming IC (BFIC). An eight-channel

In this work, an eight-port MIMOn-s antenna with dual-band operation is presented. The proposed work involves several wireless applications with FR1 and FR2 millimeter-wave bands. Also, a need for conformal antenna with capability of reduced SAR can cater the need for applications in flexible electronics. The antenna includes an oval-shaped radiating patch with a circular slot printed on Rogers RT Duroid TM5880 substrate on one plane and rectangular defected-ground-structure on the other side with a dimension of 70.71 × 70.71 mm2.

Résumé :

A variable domain of heavy chain antibody (VHH) has different binding properties than conventional antibodies. Conventional antibodies prefer binding to the convex portion of the antigen, whereas VHHs prefer epitopes, such as crevices and clefts on the antigen. Therefore, developing candidates with the binding characteristics of camelid VHHs is important. Thus, To this end, a synthetic VHH library that reproduces the structural properties of camelid VHHs was constructed. First, the characteristics of VHHs were classified according to the paratope formation based on crystal structure analyses o

Résumé :

Abstract Developing B cells in mutant ali/ali rabbits predominantly utilize VH4 during VDJ gene rearrangement. However, most of the VH4-utilizing B cells encounter a severe developmental block at the pre-B cell stage. In contrast, wildtype rabbit B cells predominantly rearrange VH1, a gene &gt;90% identical to VH4, and develop normally. We seek to determine how these nearly identical VH genes have profoundly different effects on B cell development. We hypothesize that VH4-utilizing cells are blocked at the pre-B stage due to weak interaction of the μ-chain with surrogate light chain (SL).
