Educational Factors Predicting Middle-Income Trap and International Competitiveness Index in Southeast Asia

The middle-income trap (MIT) refers to the state that middle-income economies have found it challenging to upgrade to reach the high-income stage over an extended period. Overcoming the MIT has long been discussed as an important social issue, notably in Southeast Asia. One major problem in addressing the MIT is directly linked to fewer job opportunities and an unstable income. Promoting industrialization has been the most efficient way to solve the problem. However, little previous research has been conducted on the influence of the enrollment rate in secondary education on the MIT and the international competitive index (ICI) in connection with the barrier issue of industrialization. Tran’s economic development stage model and the industrial development model were used to examine the predictive relationships between the economic development stage and education levels. Using secondary data compiled between 1999 and 2018 primarily from the World Development Indicators and the UN Comtrade Database, and multiple linear regression modeling, the strength of secondary education predicting the percentage change in R2 variance in the MIT and ICI was evaluated in nine Asian economies. Using log transformed data, secondary education alone was not found to be a superior predictor (F [1, 168] = .124, p = .725) for the MIT and (F [1, 175] = .147, p = .702) for the ICI respectively. Tertiary education was found to be a significant predictor in both models (F [1, 168] = 43.09, p = .000) and (F [1, 175] = 7.12, p = .008) respectively and is thus a major factor in escaping the MIT and upgrading the ICI. Positive social change emanates through continued policy support of advancing education as a means to escape the MIT and to promote advancements of the ICI

Comparison of Various Serum Protein Values in the Japanese and the Japanese-Americans Resident in the United States

Measurements were made of various types of proteins, that is α1-antitrypsin, α1-acid glycoprotein, α2-HS glycoprotein, haptoglobin, α2-macroglobulin, transferrin, C3, IgG, IgA and lgM, in the serum of the Japanese-Americans living in Hawaii and the Japanese-Americans living in Los Angeles who are assumed to be genetically almost identical to the Japanese in Hiroshima Prefecture but are known to have a higher intake of animal fats but a lower intake of complex carbohydrates. These were compared with those of the Japanese in Hiroshima Prefecture. α2-macroglobulin values in serum of the male Japanese-Americans living in Hawaii of ages 30-39 years, 40-49 years, and 50-59 years were significantly lower than those of the residents in Hiroshima Prefecture, but no significant difference in these values could be observed between the Japanese-Americans living in Los Angeles and the Japanese in Hiroshima Prefecture. No significant difference could be observed in the values of other serum proteins in all age groups. These findings indicate that the difference in intake volume of animal fats and complex carbohydrates did not affect these serum protein values

Identification of PNG kinase substrates uncovers interactions with the translational repressor TRAL in the oocyte-to-embryo transition

The Drosophila Pan Gu (PNG) kinase complex regulates hundreds of maternal mRNAs that become translationally repressed or activated as the oocyte transitions to an embryo. In a previous paper (Hara et al., 2017), we demonstrated PNG activity is under tight developmental control and restricted to this transition. Here, examination of PNG specificity showed it to be a Thrkinase yet lacking a clear phosphorylation site consensus sequence. An unbiased biochemical screen for PNG substrates identified the conserved translational repressor Trailer Hitch (TRAL). Phosphomimetic mutation of the PNG phospho-sites in TRAL reduced its ability to inhibit translation in vitro. In vivo, mutation of tral dominantly suppressed png mutants and restored Cyclin B protein levels. The repressor Pumilio (PUM) has the same relationship with PNG, and we also show that PUM is a PNG substrate. Furthermore, PNG can phosphorylate BICC and ME31B, repressors that bind TRAL in cytoplasmic RNPs. Therefore, PNG likely promotes translation at the oocyte-to-embryo transition by phosphorylating and inactivating translational repressors.National Institutes of Health (U.S.) (Grant GM39341)National Institutes of Health (U.S.) (Grant GM118090

Effect of Ascorbic Acid on Bronchoconstriction Induced by Methacholine Inhalation Challenge in Healthy Subjects

We investigated the effect of ascorbic acid (1.0 g orally) on bronchoconstriction induced by methacholine inhalation challenge in five healthy subjects. We also measured the serum concentration of ascorbic acid on the control day and on the ascorbic acid day. The serum ascorbic acid levels in all subjects increased on the ascorbic acid day. The protective effect of ascorbic acid against bronchoconstriction was demonstrated in three subjects. The results suggest an anti-bronchoconstrictive action of high dose ascorbic acid in some cases

Centromere/kinetochore is assembled through CENP-C oligomerization

Kinetochore is an essential protein complex required for accurate chromosome segregation. The constitutive centromere-associated network (CCAN), a subcomplex of the kinetochore, associates with centromeric chromatin and provides a platform for the kinetochore assembly. The CCAN protein CENP-C is thought to be a central hub for the centromere/kinetochore organization. However, the role of CENP-C in CCAN assembly needs to be elucidated. Here, we demonstrate that both the CCAN-binding domain and the C-terminal region that includes the Cupin domain of CENP-C are necessary and sufficient for chicken CENP-C function. Structural and biochemical analyses reveal self-oligomerization of the Cupin domains of chicken and human CENP-C. We find that the CENP-C Cupin domain oligomerization is vital for CENP-C function, centromeric localization of CCAN, and centromeric chromatin organization. These results suggest that CENP-C facilitates the centromere/kinetochore assembly through its oligomerization.Hara M., Ariyoshi M., Sano T., et al.

Predictors of sedation period for critical illness patients focusing on early rehabilitation on the bed

There are various interventions of rehabilitation on the bed, but these are time-consuming and cannot be performed for all patients. The purpose of this study was to identify the patients who require early mobilization based on the level of sedation. We retrospectively evaluated the data of patients who underwent physical therapy, ICU admission of > 48 h, and were discharged alive. Sedation was defined as using sedative drugs and a Richmond Agitation–Sedation Scale score of < − 2. Multiple regression analysis was performed using sedation period as the objective variable, and receiver operating characteristic (ROC) curve and Spearman’s rank correlation coefficient were performed. Of 462 patients admitted to the ICU, the data of 138 patients were analyzed. The Sequential Organ Failure Assessment (SOFA) score and non-surgery and emergency surgery cases were extracted as significant factors. The ROC curve with a positive sedation period of more than 3 days revealed the SOFA cutoff score was 10. A significant positive correlation was found between sedation period and the initial day on early mobilization. High SOFA scores, non-surgery and emergency surgery cases may be indicators of early mobilization on the bed in the ICU

Successful Surgical Treatment of a Spontaneous Rupture of the Esophagus Diagnosed Two Days after Onset

Esophageal perforation is a relatively uncommon disease with a high rate of mortality and morbidity. Delay in the diagnosis and treatment occurs in more than 50% of cases, leading to a mortality rate of 40–60%. Primary repair is generally considered the gold standard for patients who present within the first 24 h following perforation of the esophagus. In this paper, we present a case of successful surgical treatment of spontaneous rupture of the esophagus that was diagnosed 2 days after onset. The patient was a 42-year-old man admitted to internal medicine with a diagnosis of pleuritis and complaining of chest and back pain. The next day, computed tomography revealed left-sided pleural effusion and mediastinal emphysema. An esophagogram revealed extravasation of the contrast medium from the lower left esophagus to the mediastinal cavity. These results confirmed a rupture of the esophagus, and an emergency left thoracotomy was performed. The perforation was repaired with a single-layered closure and was covered with elevated great omentum obtained by laparotomy. The patient was discharged 23 days after the first surgery. In conclusion, primary repair surgery must be selected as the best treatment beyond 24 h if the patient's general state was stable and there was no evidence of clinical sepsis

Association between hospital acquired disability and post-discharge mortality in patients after living donor liver transplantation

Background: Hospital-acquired disability (HAD) in patients who undergo living donor liver transplantation (LDLT) is expected to worsen physical functions due to inactivity during hospitalization. The aim of this study was to explore whether a decline in activities of daily living from hospital admission to discharge is associated with prognosis in LDLT patients, who once discharged from a hospital.Methods: We retrospectively examined the relationship between HAD and prognosis in 135 patients who underwent LDLT from June 2008 to June 2018, and discharged from hospital once. HAD was defined as a decline of over 5 points in the Barthel Index as an activity of daily living assessment. Additionally, LDLT patients were classified into four groups: low or high skeletal muscle index (SMI) and HAD or non-HAD. Univariate and multivariate Cox proportional hazard models were used to evaluate the association between HAD and survival.Results: HAD was identified in 47 LDLT patients (34.8%). The HAD group had a significantly higher all-cause mortality than the non-HAD group (log-rank: p < 0.001), and in the HAD/low SMI group, all-cause mortality was highest between the groups (log-rank: p < 0.001). In multivariable analysis, HAD was an independent risk factor for allcause mortality (hazard ratio [HR]: 16.54; P < 0.001) and HAD/low SMI group (HR: 16.82; P = 0.002).Conclusion: HAD was identified as an independent risk factor for all-cause mortality suggesting that it could be a key component in determining prognosis after LDLT. Future larger-scale studies are needed to consider the overall new strategy of perioperative rehabilitation, including enhancement of preoperative physiotherapy programs to improve physical function
