Macroeconomic Environment and the Level of Cash Holding: A Literature Review  [PDF]
Yingxin Chen
Open Journal of Social Sciences (JSS) , 2021, DOI: 10.4236/jss.2021.91019
Abstract: The level of corporate cash holding is mainly affected by micro factors. In the past 20 years, the relationship between the level of cash holding and macroeconomic environmental factors has attracted more and more attention. This paper first briefly discusses three traditional theories of the level of cash holding, and proposes the leading role of trade-off theory and pecking order theory in this topic. Then, it sorts the relevant literature on macroeconomic fluctuations and macroeconomic policies.
Use the Substance-over-Form Convention to Regulate the Related Transaction

International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n3p156
Abstract: Along with the coming of knowledge economic times, many enterprises form large groups by means of capital operations, including merger and purchase, reengineering, and stockholding. As a result, the relationships between enterprises tend to be more complex. Related parties and amounts of related transactions appear. For transactions or items that have inconsistent substances and forms, we must follow the substance-over-form convention in accounting. By this way, we can guarantee the quality of accounting information, regulate the accounting, and promote the development of market economy.

Journal of Cancer Therapy (JCT) , 2019, DOI: 10.4236/jct.2019.102014
Abstract: Lung cancer is one of the most prevalent cancers in the world. A cisplatin-based chemotherapy regimen is commonly used to major patients who have adenocarcinoma. Because of the limited remission rate, many patients need receive second-line treatment after receiving first-line chemotherapy. Drug screenings carried out currently are mainly from single phase. In consideration of systemic treatment, evaluation of a novel drug candidate from the point of view of first-line and second-line treatment is supposed to be important in the process of drug screening. In this review, we propose a flow of searching for new drugs, which is tailored to accommodate to first-line and second-line treatment in clinic.

Abstract:

We introduce an ultrasound elastography method for examining the ACL. It consisted of imaging the distal ACL while applying a drawer test and analyzing the resulting displacement and strain maps, where a map refers to how a variable is distributed spatially throughout an image. Our method was applied to healthy knees of cadaveric sheep to determine whether 1) our method can consistently generate displacements and strain maps in healthy ACLs; 2) displacement and strain maps are repeatable; and 3) healthy ACLs experience similar maps. We found that our method could consistently provide displacements and strain maps of the distal ACL region. Moreover, these ACLs experienced displacement and strain maps that were positively-correlated between trials, knees, and specimens. This correlation was statistically significant between pairs of trials and between left and right knees (p < 0.05). These results suggest that the maps are indeed repeatable and similar for healthy ACLs.

Abstract: To more reasonably evaluate human intake of PBDEs via dust ingestion, bioaccessibility should be taken into account. Previously, we developed an in vitro method to determine the bioaccessibility of PBDEs in food. Here, this method was adapted to determine the bioaccessibility of PBDEs in dust and the digestion conditions that influenced the bioaccessibility of PBDEs were optimized. The digestion conditions included the incubation time of dust in the intestinal digestion solution (T), the bile concentration in the intestinal digestion solution (Cbile), and the ratio of the volume of the intestinal digestion solution to dust (R). The influence of the concentrations of individual PBDE congeners (CPBDE) on the bioaccessibility of PBDEs was also investigated. Central composite design was used to build an experimental model and set experimental parameters, and response surface methodology was used to analyze the obtained data. The results showed that the bioaccessibility of PBDEs increased with the increases of Cbile and R, and was independent of T and CPBDE. Under the digestion conditions with Cbile and R being at 4.0-7.0 g/L and 150-250, respectively, the bioaccessibility of PBDEs in the method-dust varied from 39.2% to 72.8%, which were comparable with the bioaccessibility or bioavailability of PBDEs in dust/soil in the literature. Thus, the in vitro method to measure the bioaccessibility of PBDEs in dust was established and validated. Finally, the bioaccessibility of PBDEs in four natural dust samples, which ranged from 36.1% to 43.3%, were determined using the adapted method.

International Journal of Biomedical Imaging , 2007, DOI: 10.1155/2007/17131
Abstract: Purpose. To evaluate the diagnosis value of integrated positron emission tomography and computed tomography (PET/CT) with lung masses, this study emphasized the correlation between tumor size and maximum standardized uptake value (SUVmax) in selected regions of interest (ROI) of lung masses. Material and Methods. A retrospective analysis was performed on 85 patients with solid pulmonary lesions, all verified by pathology. The morphology, edge (speculated margins and lobule), size, density of pulmonary masses, and on-chest CT images were reviewed. The SUVmax in ROI of pulmonary masses was calculated. Results. Among the 85 patients with lung masses, 59 patients presented with pulmonary malignant neoplasm and 26 patients with benign lesions. The sensitivity, specificity, and accuracy were 89.8%, 61.5%, 81.2%, respectively, for PET measurement only, 88.1%, 65.4%, 81.2% for CT only, and 96.6%, 80.8%, 91.8% for PET/CT. The size of pulmonary malignant neoplasm in the 59 patients was apparently correlated with the ROI's SUVmax (r=0.617, P<.001). However, the size of pulmonary benign mass in the 26 patients was not correlated with the SUVmax. Conclusion. PET/CT is of greater value in characterization of lung masses than PET and CT performed separately. The examination of lung tumor can be further specified by the correlation between the size of pulmonary malignant neoplasm and the ROI's SUVmax.

Abstract: Aim To test the hypothesis that NAD+-carrying mesoporous silica nanoparticles (M-MSNs@NAD+) can effectively deliver NAD+ into cells to produce cytoprotective effects. Methods & Materials NAD+ was incorporated into M-MSNs. Primary rat astrocyte cultures and PC12 cells were treated with H2O2, followed by post-treatment with M-MSNs@NAD+. After various durations of the post-treatment, intracellular NAD+ levels, intracellular ATP levels and lactate dehydrogenase (LDH) release were determined. Results & Discussion M-MSNs can be effectively loaded with NAD+. The M-MSNs@NAD+ can significantly attenuate H2O2-induced NAD+ and ATP decreases in both astrocyte cultures and PC12 cells. M-MSNs@NAD+ can also partially prevent the H2O2-induced LDH release from both astrocyte cultures and PC12 cells. In contrast, the NAD+ that is spontaneously released from the M-MSNs@NAD+ is insufficient to prevent the H2O2-induced damage. Conclusions Our study has suggested the first approach that can effectively deliver NAD+ into cells, which provides an important basis both for elucidating the roles of intracellular NAD+ in biological functions and for therapeutic applications of NAD+. Our study has also provided the first direct evidence demonstrating a key role of NAD+ depletion in oxidative stress-induced ATP decreases.
