Dear Editor,Gliomas are the most prevalent malignant tumors affecting the central nervous system (CNS), categorized into low-grade gliomas (LGG) comprising CNS WHO grades 2–3, and high-grade gliomas(HGG) encompassing CNS WHO grade 4(Aldape et al., 2015). The current standard therapeutic approach involves maximal safe margin excision followed by radiotherapy and temozolomide (TMZ)treatment (Armstrong et al., 2020).However, due to the unique site and microenvironment of gliomas, patients experience limited benefits from emerging revolutionary therapies such as targeted therapy and immunotherapy (Sampson et al., 2020; Yang et al., 2022).

Grooming is an innate behavior that serves multiple purposes and has a dual nature, reflecting both comfort and stress. Auto-grooming, in particular, is highly sensitive to stressors and can be influenced by natural and synthetic anxiolytics. Researchers believe that rodent grooming can be a valuable tool in translational neurobiological studies, specifically focusing on aberrant grooming, such as the syntactic chain of grooming, which can serve as an experimental model for certain human psycho-nervous disorders.

Genetic load and inbreeding are recognized as important factors to be considered in conservation *** levels of both can increase the risk of population extinction by negatively impacting fitness-related characters in many species of plants and animals,including humans(inbreeding depression).Genomic tech-niques are increasingly used in measuring and understanding genetic load and inbreeding and their importance in evolution and *** used whole genome resequencing data from two sibling grouse species in subarctic Eurasia to quantify *** found a large range of inbreeding measured as FROH(fraction of runs of homozygosity)in individuals from different populations of Chinese Grouse(Tetrastes sewerzowi)and Hazel Grouse(***).FROH estimated from genome-wide runs of homozygosity(ROH)ranged from 0.02 to 0.24 among Chinese Grouse populations and from 0.01 to 0.44 in Hazel *** from a population of Chinese Grouse residing in the Qilian mountains and from the European populations of Hazel Grouse(including samples from Sweden,Germany and Northeast Poland)were the most inbred(FROH ranged from 0.10 to 0.23 and 0.11 to 0.44,respectively).These levels are comparable to other highly inbred populations of *** Grouse from northern China and Chinese Grouse residing in the Qinghai-Tibetan Plateau showed relatively lower inbreeding *** of the ratio between deleterious missense mutations and synonymous mutations revealed higher levels in Chinese Grouse as compared to Hazel *** results are possibly explained by higher fixation rates,mutational melt down,in the range-restricted Chinese Grouse compared to the wide-ranging Hazel ***,when we compared the relatively more severe class of loss-of-function muta-tions,Hazel Grouse had slightly higher levels than Chinese Grouse,a result which may indicate that purifying selection(purging)has been more efficient in Chinese Grouse on this class of mutations.
