Multitarget ligands that comprise opioid/nonopioid pharmacophores for pain management: Current state of the science.

Chronic pain, which affects more than one-third of the world's population, represents one of the greatest medical challenges of the 21st century, yet its effective management remains sub-optimal. The 'gold standard' for the treatment of moderate to severe pain consists of opioid ligands, such as morphine and fentanyl, that target the µ-opioid receptor (MOP). Paradoxically, these opioids also cause serious side effects, including constipation, respiratory depression, tolerance, and addiction.

Barriers to Mohs Micrographic Surgery in Japanese Patients With Basal Cell Carcinoma.

Mohs micrographic surgery (MMS) is a well-recognized treatment for nonmelanoma skin cancer worldwide, but Japan has lagged behind many other countries in adopting MMS. We present a series of 5 cases of MMS utilized in Japanese patients. All cases had a favorable outcome, each benefiting from MMS with a smaller final defect or a higher likelihood of cure than standard excision.

Plutonium isotopes can be used to model soil erosion in Kenya.

Climate change poses an immediate threat to tropical soils with changes in rainfall patterns resulting in accelerated land degradation processes. To ensure the future sustainability of arable land, it is essential to improve our understanding of the factors that influence soil erosion processes. This work aimed to evaluate patterns of soil erosion using the activity of plutonium isotopes (Pu) at sites with different land use and clearance scale in the Winam Gulf catchment of Lake Victoria in Kenya.

High species richness in the lichen genus (): 34 species in the dolichorhizoid and scabrosoid clades of section , including 24 new to science.

Applying molecular methods to fungi establishing lichenized associations with green algae or cyanobacteria has repeatedly revealed the existence of numerous phylogenetic taxa overlooked by classical taxonomic approaches. Here, we report taxonomical conclusions based on multiple species delimitation and validation analyses performed on an eight-locus dataset that includes world-wide representatives of the dolichorhizoid and scabrosoid clades in section of the genus . Following the recommendations resulting from a consensus species delimitation approach and additional species validation analysis (BPP) performed in this study, we present a total of 25 species in the dolichorhizoid clade and nine in the scabrosoid clade, including respectively 18 and six species that are new to science and formally described.
