As part of an ongoing survey of scorpion diversity in Colima, Mexico, the isolated mountain Cerro Grande, part of the Biosphere Reserve Sierra de Manantlán, was investigated. Centruroides possanii sp. nov., the fifth species of the genus from the state, was discovered during fieldwork in the massif and is described in the present paper. Physiographical and climatic features of Cerro Grande may restrict the range of this new species; thus, we hypothesized that it may be a microendemic species that requires priority conservation. The new species is not assigned to any Centruroides species group recognized because some of its morphological features do not fit the current diagnosis of any of these groups, and these different groups are non-monophyletic and consequently ill-diagnosed. The new species is profusely illustrated, particularly the hemispermatophore. A distribution map is presented along with the other two more common species distributed in Colima. Because only indirect data on the potency of its venom is available, the medical importance of this new species described here is yet to be known.

We present the results of a 1-year study that quantified salt levels in stormwater, soils, and plant tissues from 14 stormwater detention basins across Northern VA in an above-average snow year. We characterize (1) the level of salt stress plants experience, (2) the extent to which current plant communities feature salt tolerant species, and (3) the capacity of these species to phytoremediate soils and reduce the impacts of deicer and anti-icer use. Our results suggest that detention basin vegetation experience a range of salt stress levels that depend on drainage area type (roads: moderate to high > parking lots: low to moderate > pervious areas: none).

Wound bacterial infections not only impede the healing process but can also give rise to a range of serious complications, thereby posing a substantial risk to human health. Developing effective wound dressings incorporating phototherapy functionalities, specifically photothermal therapy (PTT) and photodynamic therapy (PDT), remains a critical area of research in modern wound care. Existing PTT-PDT systems often suffer from challenges such as nanoparticle aggregation and inefficient reactive oxygen species (ROS) generation, which are essential for therapeutic efficacy.

Targeting DNA repair mechanisms, particularly PARP-1 inhibition, has emerged as a promising strategy for developing anticancer therapies. we designed and synthesized two 2-thiazolecarboxaldehyde thiosemicarbazone palladium(II) complexes (C1 and C2), and evaluated their anti-cancer activities. These Pd(II) complexes exhibited potent PARP-1 enzyme inhibition and demonstrated considerable antiproliferative activity against various cancer cell lines.
