  • Streptococcus pneumoniae, pneumococcus, is the most common cause of community-acquired pneumonia (CAP). CAP is an important infectious disease with high morbidity and mortality, and it is still one of the leading causes of death worldwide. Many genetic factors of the host and various environmental factors surrounding it have been studied as important determinants of the pathophysiology and outcomes of pneumococcal infections. Various cytokines, including transforming growth factor $(TGF)-{\beta}1$, are involved in different stages of the progression of pneumococcal infection. $TGF-{\beta}1$ is a cytokine that regulates a wide range of cellular and physiological functions, including immune and inflammatory responses. This cytokine has long been known as an anti-inflammatory cytokine that is critical to preventing the progression of an acute infection to a chronic condition. On the other hand, recent studies have unveiled the diverse roles of $TGF-{\beta}1$ on different stages of pneumococcal infections other than mitigating inflammation. This review summarizes the recent findings of the role of $TGF-{\beta}1$ on the pathophysiology of pneumococcal infections, which is fundamental to developing novel therapeutic strategies for such infections in immune-compromised patients.

  • The main aim of study is to identify the factors that affect the purchasing intention of young adults. The reference group is an important factor in determining the underlying causes of young adults' purchasing intentions. However, the literature states that young adults prefer to buy brands they trust in order to eliminate the risks that may arise when buying products they may not know. Moving from this perspective, the study proposes a conceptual model that including structural relationships between brand trust, reference group, and purchasing intention. The study aims to contribute to the literature by discussing the moderator role of brand trust in this structure. A series of hypotheses are tested via a survey completed by 749 young people between the ages of 20 and 30 living in Istanbul, Turkey. The data were analyzed with IBM SPSS-23 and AMOS-18 program. In addition to descriptive, reliability, and factor (exploratory and confirmatory) analysis, hierarchical regression analysis was performed to test the research hypotheses. The results show that the reference group positively influences the purchasing intention, and brand trust plays a moderating role in this relationship. The findings are discussed and some practical suggestions are made for mobile phone manufacturers.

  • The purpose of the current study is to examine the role of mothers' personality traits in predicting their parenting stress. The study subjects were married working woman who live at Gyeonggi-do and has their first child studying in elementary, middle, or high school. Collected data were analyzed with SPSS WIN 18.0 program. The results were as follows.: First, it has been shown through examination of the general tendency of observation subjects' relative factor, that many have above average parenting stress. The compositing factor for parenting stress were mainly the burden and distress of the parent role. Second, the differences in parenting stress were affected by relative variables in accordance with the general features of the study object. If the younger the parent, the higher the education, the lower the age of the first child, and if there were a child assistant after school, the parenting stress became larger. Third, after controlling for demographic characteristics, employed mothers' neuroticism significantly predicted greater parenting stress. When mothers had more conscientiousness and openness, they reported less parenting stress which implied that interpretation and perception of child rearing experiences can vary depending on personality and predict parenting stress of working mothers.

  • The antioxidant responsive element (ARE) is a cis-acting regulatory element of genes encoding phase II detoxification enzymes and antioxidant proteins, such as NAD(P)H: quinone oxidoreductase 1, glutathione S-transferases, and glutamate-cysteine ligase. Interestingly, it has been reported that Nrf2 (NF-E2-related factor 2) regulates a wide array of ARE-driven genes in various cell types. Nrf2 is a basic leucine zipper transcription factor, which was originally identified as a binding protein of locus control region of ss-globin gene. The DNA binding sequence of Nrf2 and ARE sequence are very similar, and many studies demonstrated that Nrf2 binds to the ARE sites leading to up-regulation of downstream genes. The function of Nrf2 and its downstream target genes suggests that the Nrf2-ARE pathway is important in the cellular antioxidant defense system. In support of this, many studies showed a critical role of Nrf2 in cellular protection and anti-carcinogenicity, implying that the Nrf2-ARE pathway may serve as a therapeutic target for neurodegenerative diseases and cancers, in which oxidative stress is closely implicated.

  • Panax ginseng is a well-known economic medical plant that is widely used in Chinese traditional medicine. This species contains a unique class of natural products-ginsenosides. Recent clinical and experimental studies have presented numerous lines of evidence on the promising role of ginsenosides on different diseases including neurodegenerative diseases, cardiovascular diseases, and certain types of cancer. Nowadays, most of the attention has focused on ginsenoside Rd as a neuroprotective agent to attenuate ischemic stroke damages. Some of the evidence showed that ginsenoside Rd ameliorates ischemic stroke-induced damages through the suppression of oxidative stress and inflammation. Ginsenoside Rd can prolong neural cells' survival through the upregulation of the endogenous antioxidant system, phosphoinositide-3-kinase/AKT and extracellular signal-regulated protein kinase 1/2 pathways, preservation of mitochondrial membrane potential, suppression of the nuclear factor-kappa B, transient receptor potential melastatin, acid sensing ion channels 1a, poly(ADP-ribose) polymerase-1, protein tyrosine kinase activation, as well as reduction of cytochrome c-releasing and apoptosis-inducing factor. In the current work, we review the available reports on the promising role of ginsenoside Rd on ischemic stroke. We also discuss its chemistry, source, and the molecular mechanism underlying this effect.
