A highly efficient cloning vector was constructed for cloning PCR products by inserting an 80 bp DNA fragment into pGEM-5zf (+) vector. The Xcm I digestion of this vector gave rise to a 3' overhanging deoxythymidine offering the possibility of cloning PCR products with 3' adenosine overhang created by Taq DNA polymerase. Furthermore, two EcoR I sites were added to the construct for identification of recombinant plasmids using a single restriction enzyme. Taken together, the more efficient cloning performance and the lower cost of this vector as compared to the commercial T vector, suggests that it may be one of the best T vectors for cloning of PCR products.

Passion fruit woodiness disease (PWD), caused by cowpea aphid-borne mosaic virus (CABMV), severely damages leaves and fruits, compromising passion fruit production. The dynamics of this infection in Passiflora spp. are still poorly understood.

Background: Macrophage activation and polarization play pivotal roles in the inflammatory response and myocardial injury associated with myocardial infarction (MI). Modulating macrophage polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype is a promising therapeutic approach for MI. Shuxuening injection (SXNI) is extensively utilized in clinical settings for MI treatment and has demonstrated therapeutic efficacy.

Reactive oxygen species (ROS) produced by NADPH oxidase promote contraction of peripheral arteries, which is especially pronounced in early postnatal period in comparison to adulthood, but the mechanisms of such vasomotor influence are poorly understood. We tested the hypothesis that Rho-kinase and protein kinase C (PKC) mediate procontractile influence of NADPH oxidase derived ROS in peripheral artery of early postnatal rats. In addition, we evaluated the involvement Src-kinase and L-type voltage-gated Ca channels (LTCC) into procontractile influence of ROS, produced by NADPH oxidase, because of their known interplay with Rho-kinase and PKC pathways.

We aimed to explore the role of ikarugamycin (IKA) in breast cancer, its connection with hexokinase-2 (HK-2) repression, and tissue factor (TF). This study sought to extend the role of HK-2 as a TF activator in a comprehensive analysis of these interactions from the enzyme, gene, and protein levels. The investigation was performed with MDA-MB-231 and MCF-7 breast cancer lines.
