From Federalism, Chinese Style to Privatization, Chinese style

In 1994 China began a profound reform of its state-owned enterprises. We first describe and characterize this progress in two areas: privatization of small state-owned enterprises at the county level and mass layoffs of excess state workers at the city level. Local governments have initiated these reforms, which are proceeding in economically and politically sensible ways. We then argue that privatization, Chinese style, rests on an adequate economic and political foundation - federalism, Chinese style. We suggest a range of incentives that propel local governments toward SOE reform, including their harder budget constraints and increased competition from the non-state sector. In this sense, federalism, Chinese style, has induced privatization, Chinese style.http://deepblue.lib.umich.edu/bitstream/2027.42/39516/3/wp126.pd

Evaluate the effects of low-intensity pulsed ultrasound on dental implant osseointegration under type II diabetes

Objective: The objective of this study is to assess the impact of low-intensity pulsed ultrasound (LIPUS) therapy on the peri-implant osteogenesis in a Type II diabetes mellitus (T2DM) rat model.Methods: A total of twenty male Sprague-Dawley (SD) rats were randomly allocated into four groups: Control group, T2DM group, Control-LIPUS group, and T2DM-LIPUS group. Implants were placed at the rats’ bilateral maxillary first molar sites. The LIPUS treatment was carried out on the rats in Control-LIPUS group and T2DM-LIPUS group, immediately after the placement of the implants, over three consecutive weeks. Three weeks after implantation, the rats’ maxillae were extracted for micro-CT, removal torque value (RTV), and histologic analysis.Results: Micro-CT analysis showed that T2DM rats experienced more bone loss around implant cervical margins compared with the non-T2DM rats, while the LIPUS treated T2DM rats showed similar bone heights to the non-T2DM rats. Bone-implant contact ratio (BIC) were lower in T2DM rats but significantly improved in the LIPUS treated T2DM rats. Bone formation parameters including bone volume fraction (BV/TV), trabecular thickness (Tb.Th), bone mineral density (BMD) and RTV were all positively influenced by LIPUS treatment. Histological staining further confirmed LIPUS’s positive effects on peri-implant new bone formation in T2DM rats.Conclusion: As an effective and safe treatment in promoting osteogenesis, LIPUS has a great potential for T2DM patients to attain improved peri-implant osteogenesis. To confirm its clinical efficacy and to explore the underlying mechanism, further prospective cohort studies or randomized controlled trials are needed in the future

Embracing the Market: Entry into Self-Employment in Transitional China, 1978-1996

This paper introduces labor market transition as an intervening process by which the macro institutional transition to a market economy alters social stratification outcome. Rather than directly addressing income distribution, it examines the pattern of workers’ entry into self-employment in reform-era China (1978-1996), focusing on rural-urban differences and the temporal trend. Analyses of data from a national representative survey in China show that education, party membership and cadre status all deter urban workers’ entry into self-employment, while education promotes rural workers’ entry into self-employment. As marketization proceeds, the rate of entry into self-employment increases in both rural and urban China, but urban workers are increasingly more likely to take advantages of the new market opportunities. In urban China, college graduates and cadres are still less likely to be involved in self-employment, but they are becoming more likely to do so in the later phase of reform. The diversity of transition scenarios is attributed to rural-urban differences in labor market structures.http://deepblue.lib.umich.edu/bitstream/2027.42/39897/3/wp512.pd

Research progress on dedifferentiated fat cells and their application in oral and maxillofacial bone tissue engineering

The identification of suitable seed cells represents a critical scientific problem to be solved in the field of oral and maxillofacial bone tissue regeneration. The application of adipose-derived stem cells (ASCs) in tissue and organ repair and regeneration has been studied extensively. In recent years, dedifferentiated fat (DFAT) cells have also shown broad application prospects in the field of bone tissue engineering. DFAT cells express stem cell-related markers and have the potential to differentiate into adipocytes, osteoblasts, chondrocytes, nerve cells, cardiomyocytes and endothelial cells. In addition, DFAT cells also have the advantages of minimally invasive acquisition, strong proliferation and high homogeneity. Currently, all studies involving the application of DFAT cells in scaffold-based and scaffold-free bone tissue engineering can confirm their effectiveness in promoting bone regeneration. However, cytological research still faces some challenges, including relatively low cell culture purity, unclear phenotypic characteristics and undefined dedifferentiation mechanisms. It is believed that with the continuous development and improvement of isolation, culture, identification and directional induction of osteogenic differentiation methods, DFAT cells are expected to become excellent seed cells in the field of oral and maxillofacial bone tissue engineering in the future

From Federalism, Chinese Style, to Privatization, Chinese Style

In 1994, China began a profound reform of its state-owned enterprises (SOE). We first describe and characterize this progress in two areas: privatization of small state-owned enterprises (SOEs) at the county level and mass lay-offs of excess state workers at the city level. Local governments have initiated these reforms, which are proceeding in economically and politically sensible ways. We then argue that privatization, Chinese style, rests on an adequate economic and political foundation – federalism, Chinese style. We suggest a range of incentives that propel local governments toward SOE reform, including their harder budget constraints and increased competition from the non-state sector. In this sense, Chinese style federalism, has induced Chinese style privatization.China; Federalism; local governments; Privatization; Restructuring

Theoretical and experimental study of new deep eutectic solvents for extraction of perfluorinated iodoalkanes

There is a lack of attention and reporting in aspects of the neutral/nonionic perfluoroalkyl substances (PFASs) and corresponding treatment mechanisms. Herein, new function-oriented deep eutectic solvents (DESs) with pyridine moiety were designed for perfluorinated iodoalkanes extraction from the oil phase. The effect of hydrogen bond acceptor (HBA) functional groups on the effectiveness of targets retrieval was investigated. Moreover, different structural, quantum-chemical, solvatochromic, and statistical thermodynamics parameters were conducted, calculated, and correlated to the distribution coefficients of the studied DESs. Results showed that functional groups of HBAs significantly affected the extraction effectiveness of eutectic mixtures. The pyridine ring-based DESs with the CO group possessed the highest extraction efficiencies among the studied groups. To some extent, the extraction performances of the DES were substantially affected by the electrostatic potential extrema of the donor halogen atom and pyridine analogues. For targets with relatively short alkyl chain length, the topological indices had a positive relationship with the treatment efficacy of the DESs, and the quantum-chemical parameters of these solvents had a strong negative relationship with them. For targets with long alkyl chain length, the solvatochromic parameters of DES had a great influence on the distribution coefficients and also on the selectivity of these solvents. Furthermore, the halogen and hydrogen bonds presented cooperativity, clarifying via quantum-chemistry calculations. The synergism mechanism between them is beneficial to the extraction of perfluorinated iodoalkanes. Besides shedding light on the structure–property-performance relationships of the DESs, these findings also provided novel insights into the directional design and selection of DESs

The Role of Noncoding RNA in the Transmission and Pathogenicity of Flaviviruses

Noncoding RNAs (ncRNAs) constitute a class of RNA molecules that lack protein-coding capacity. ncRNAs frequently modulate gene expression through specific interactions with target proteins or messenger RNAs, thereby playing integral roles in a wide array of cellular processes. The Flavivirus genus comprises several significant members, such as dengue virus (DENV), Zika virus (ZIKV), and yellow fever virus (YFV), which have caused global outbreaks, resulting in high morbidity and mortality in human populations. The life cycle of arthropod-borne flaviviruses encompasses their transmission between hematophagous insect vectors and mammalian hosts. During this process, a complex three-way interplay occurs among the pathogen, vector, and host, with ncRNAs exerting a critical regulatory influence. ncRNAs not only constitute a crucial regulatory mechanism that has emerged from the coevolution of viruses and their hosts but also hold potential as antiviral targets for controlling flavivirus epidemics. This review introduces the biogenesis of flavivirus-derived ncRNAs and summarizes the regulatory roles of ncRNAs in viral replication, vector-mediated viral transmission, antiviral innate immunity, and viral pathogenicity. A profound comprehension of the interplay between ncRNAs and flaviviruses will help formulate efficacious prophylactic and therapeutic strategies against flavivirus-related diseases
