The human microbiota-associated(HMA) mice model, especially the germ-free(GF)-humanized mice, has been widely used to probe the causal relationships between gut microbiota and human diseases such as type 1 diabetes(T1D). However, most studies have not clarified the extent to which the reconstruction of the human donor microbiota in recipient mice correlates with corresponding phenotypic reproducibility. In this study, we transplanted fecal microbiota from five patients with T1D and four healthy people into GF mice, and microbiota from each donor were transplanted into 10 mice. Mice with similar microbiota structure to the donor exhibited better phenotypic reproducibility. The characteristics of the microbial community assembly of donors also influenced the phenotypic reproducibility in mice, and individuals with a higher proportion of stochastic processes showed more severe disorders. Microbes enriched in patients with T1D had a stronger colonization potential in mice with impaired glucose metabolism, and microbiota functional features related to T1D were better reproduced in these mice. This indicates that assembly traits and colonization efficacy of microbiota influence phenotypic reproducibility in GF-humanized mice. Our findings provide important insights for using HMA mice models to explore links between gut microbiota and human diseases.

Backgroud: Current understanding of injury and regeneration of islet β-cells in diabetes is mainly based on rodent studies. The tree shrew is now generally accepted as being among the closest living relatives of primates, and has been widely used in animal experimentation. However, there are few reports on islet cell composition and regeneration of β-cells in tree ***: In this study, we examined the changes in islet cell composition and regeneration of β-cells after streptozotocin(STZ) treatment in tree shrews compared with Sprague-Dawley rats. Injury and regeneration of islet β-cells were observed using hematoxylin and eosin(HE) staining and immunohistochemical staining for insulin, glucagon, somatostatin and ***: Our data showed that in rats islet injury was most obvious on day 3 after injection, and islet morphologies were significantly restored by day 21. Regeneration of islet β-cells was very pronounced in rats, and mainly involved regeneration of centro-acinar cells and transformation of extra-islet ductal cells. In tree shrews, the regeneration of islet β-cells was not as significant. On days 3 and 7, only scattered regenerated cells were observed in the remaining islets. Further, no regeneration of centro-acinar cells was ***: The results suggest that the repair mechanism of islet β-cells in tree shrews is similar to that of humans.

Soil is the largest carbon(C) reservoir in terrestrial ecosystems and plays a crucial role in regulating the global C cycle and climate *** nitrogen(N) deposition has been widely considered as a critical factor affecting soil organic carbon(SOC) storage, but its effect on SOC components with different stability remains unclear. Here, we analyzed extensive empirical data from 304 sites worldwide to investigate how SOC and its components respond to N addition. Our analysis showed that N addition led to a significant increase in bulk SOC(6.7%), with greater increases in croplands(10.6%) and forests(6.0%) compared to grasslands(2.1%). Regarding SOC components, N addition promoted the accumulation of plant-derived C(9.7%–28.5%) over microbial-derived C(0.2%), as well as labile(5.7%) over recalcitrant components(–1.2%), resulting in a shift towards increased accumulation of plant-derived labile C. Consistently, N addition led to a greater increase in particulate organic C(11.9%) than mineral-associated organic C(3.6%), suggesting that N addition promotes C accumulation across all pools, with more increase in unstable than stable pools. The responses of SOC and its components were best predicted by the N addition rate and net primary productivity. Overall, our findings suggest that N enrichment could promote the accumulation of plant-derived and non-mineral associated C and a subsequent decrease in the overall stability of soil C pool, which underscores the importance of considering the effects of N enrichment on SOC components for a better understanding of C dynamics in soils.

三元共晶是在二元共晶的基础上发展的一种新型共晶设计策略,可以在不影响药物固有生物活性和相应药理活性的情况下改善药物的理化性质,因此三元共晶在药物研究和开发方面具有巨大的潜力。由于三元共晶会涉及三种不同分子的复杂组装,其复杂程度随着参与药物共晶的分子种类和数量的增加而增加,潜在的共晶氢键结合位点数量也随之增加,所以很难获得特定的三元共晶,关于特定三元共晶系统的微观分子结构方面的报道也很少。为了理解三元共晶结构的氢键形式,通过检测手段获取三元共晶体系中相关二元及三元共晶的分子结构信息对了解三元药物共晶的复杂形成过程尤为重要。采用机械研磨方法成功地合成了异烟酰胺-戊二酸、吡嗪酰胺-戊二酸二元共晶和异烟酰胺-戊二酸-吡嗪酰胺三元共晶,通过太赫兹时域光谱(THz-TDS)和密度泛函理论(DFT)计算对二元共晶和三元共晶结构进行研究。太赫兹光谱实验结果表明,二元和三元共晶都显示出各自独特的光谱特征。晶体结构分析表明异烟酰胺-戊二酸-吡嗪酰胺三元共晶结构中戊二酸一侧羧基中的羟基与异烟酰胺中的吡啶N形成羧基-吡啶N氢键异合成元,而异烟酰胺中的酰胺与吡嗪酰胺中的酰胺形成酰胺-酰胺氢键同合成元。最后,将DFT计算得到的理论太赫兹光谱与实验进行对比,发现异烟酰胺-戊二酸、吡嗪酰胺-戊二酸二元共晶氢键形式的叠加与异烟酰胺-戊二酸-吡嗪酰胺三元共晶的氢键形式并不是完全一致的,但是这两种二元共晶的氢键形式对预测三元共晶的氢键形式具有极为重要的参考价值。这些结果为新兴的药物共晶领域在分子水平上研究特定三元共晶的分子组装和分子间相互作用提供了丰富的信息和独特的方法。

The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp
