5 ± 0.9 [26.8, 30.3] vs 28.5 ± 0.6 [27.1, 29.9] ms, P = 0.719) were nonsignificant. T2∗ was significantly increased in the lesion-sided MT vs the LT for the JOCD-affected knees (21.5 ± 0.7 [20.1, 22.9] vs 18.0 ± 0.7 [16.5, 19.5] ms, P = 0.002), but this same difference was also observed between the MT and LT in control knees (21.0 ± 0.6 [19.7, 22.3] vs 18.1 ± 1.1 [15.8, 20.4] ms, P = 0.037). There was no significant T2∗ difference between the affected- and control-knee MT (21.5 ± 0.7 [20.1, 22.9] vs 21.0 ± 0.6 [19.7, 22.3] ms, P = 0.905). T2∗ within the lesion-sided MFC was not correlated with patient age (R = 0.20, P = 0.28) or lesion volume (R = 0.06, P = 0.75). T2∗ values were slightly increased near lesions in later-stage JOCD subjects but without statistical significance. CONCLUSIONS T2∗ relaxations times were not significantly different from control sites in the articular cartilage overlying JOCD lesions in the MFC or adjacent MT cartilage in early-stage JOCD. The R51Q mutation in sorting nexin 10 (SNX10) was shown to cause a lethal genetic disease in humans, namely autosomal recessive osteopetrosis (ARO). We describe here the first R51Q SNX10 knock-in mouse model and show that mice homozygous for this mutation exhibit massive, early-onset, and widespread osteopetrosis. The mutant mice exhibit multiple additional characteristics of the corresponding human disease, including stunted growth, failure to thrive, missing or impacted teeth, occasional osteomyelitis, and a significantly-reduced lifespan. Osteopetrosis in this model is the result of osteoclast inactivity that, in turn, is caused by absence of ruffled borders in the mutant osteoclasts and by their inability to secrete protons. These results confirm that the R51Q mutation in SNX10 is a causative factor in ARO and provide a model system for studying this rare disease. Xuezhikang (XZK), an extract derived from red yeast rice, is commonly employed as a traditional Chinese medicine for treating coronary heart disease, improving endothelial function, decreasing blood lipids and preventing other cardiovascular events both within China and globally. However, there have not been studies of the toxicity associated with XZK. In this publication we hope to summarize and evaluate an acute study, a 26-week chronic toxicity study, and the genetic toxicity potential of XZK. Firstly, Sprague Dawley (SD) rats were treated with XZK at dose of 10 g/kg to observe the acute toxicity. Then, we sought to assess the toxicity of XZK (0, 500, 1000, and 2000 mg/kg) in SD rats for 26 weeks with a 4-week recovery period. Lastly, we assessed the genotoxicity of XZK utilizing an Ames test, chromosomal aberration assay, and mammalian micronucleus test. The results of the acute study, XZK did not induce toxicity up to the maximum doses of 10 g/kg in rats, so an LD50 could not be determined. In the chronic study, XZK administrated via gavage did not alter weight, food intake, urinalysis parameters, hematological analysis parameters, organ weight, organ to weight ratio, microscopic and macroscopic examination of organs. Also, we found no genotoxicity markers at any dose of XZK tested. The results revealed that the no observed adverse effect level (NOAEL) for XZK, based on the 26-week toxicity study, was 2000 mg/kg. BACKGROUND ST11 Klebsiella pneumoniae is among the most important clinical pathogen in China, and KL47 and KL64 are the dominant K-types of these strains. Understanding the genomic characteristics of these strains would be critical to their anti-infection treatment. METHODS 364 genome sequences of ST11 K. pneumoniae strains isolated from 13 countries from 2003 to 2018 were collected. These genome sequences included 338 downloaded from NCBI database and 26 newly sequenced. Phylogenic analysis, pan-genome and unique genes, resistance and virulence genes analysis were conducted to elucidate the molecular characteristics of these strains. RESULTS A total of 19,732 genes were identified from the 364 ST11 strains, and the pan-genome was open, indicating the genetic diversity of ST11 K. pneumoniae. These strains were clustered into 3 clades. Clade 1 contained the most various K-types (14/15, 93.3%) and unique genes. KL47 and KL64 were the dominant K-types of clade 2 and clade 3, accounting for 100% and 99.4% of strains in each clade. KL64 strains contained the most virulence genes, including iucA and rmpA, and the two genes tend to coexist. In addition, strains in clade 1 were isolated from all 13 countries, and the strains in clade 2 and 3 mainly from China. CONCLUSION ST11 K. pneumoniae strains of KL64 was becoming a newly emerged superbug with more resistance and virulence genes in China, which was significant different from other countries, and we should be alert the dissemination of this subclone. Thiamet G Alcohol Use Disorder (AUD) has a major national impact, affecting over 18 million people, causing approximately 88,000 deaths and costing upward of $220 billion annually in the US. Unfortunately, FDA-approved AUD pharmaceuticals are few, and clinical benefits are mostly ineffective in patients suffering AUD. Therefore, the identification of novel targets and/or innovative methods for the development of safe and effective medications represents a critical public health need. Previously, we reported that avermectin compounds (Ivermectin [IVM] and moxidectin [MOX]) significantly reduced ethanol intake in male and female mice. However, avermectin compounds are readily effluxed by P-glycoprotein (Pgp/ABCB1) in the blood-brain barrier (BBB), resulting in reduced retention time by the drugs in the central nervous system (CNS). As such, the doses of IVM or MOX and the timeframe for significant reductions of ethanol intake is not ideal. Here we evaluate a novel combinatorial strategy involving IVM and tariquidar (TQ), a third-generation efflux inhibitor of Pgp, to reduce the dosing necessary for improving alcohol (ethanol) consumption behavior. We tested male C57BL/6J mice using a two-bottle choice study to evaluate ethanol consumption and preference. We found that injecting 10 mg/kg of TQ 30 minutes prior to IVM, resulted in a five-fold improvement in the efficacy of IVM (dosed at 0.5 mg/kg), resulting in a significant reduction in ethanol intake and preference. Notably, the reduction by IVM was well tolerated, and no adverse effects were identified when tested at doses ranging from 0.50 mg/kg to 2.0 mg/kg. Collectively, our findings indicate that IVM, in combination with TQ, increases its efficacy in the CNS for reducing ethanol consumption. This work demonstrates a novel combinatorial drug strategy that allows new opportunities for drugs with poor CNS retention, such as IVM, to demonstrate improved potency and potentially improved safety.
