Polymorphism of Xenobiotic Detoxification Genes and Male Infertility

Infertility is a multifactorial disease caused by both genetic and environmental factors. It is observed in 10–15% of couples, among which male infertility contributes for half the cases. Thus, identifying underlying causes of male infertility and for proper methods for treating and/or preventing sperm damage is of paramount importance. It is found that one of the factors that has been recently implicated in male infertility is oxidative stress, mediated by reactive oxygen species (ROS) that are produced during the metabolic process, as well as during the exposure to environmental chemical agents and their interaction with tissue-specific enzymes. Several studies have identified genetic variations at different loci, connected with male infertility, that may shed light on some idiopathic cases of seminal fluid abnormalities. In this chapter, we make an effort to decipher the contribution of polymorphisms in xenobiotic detoxification genes in the male infertility development

THE EFFECT OF CROSS-BORDER MERGERS AND ACQUISITIONS ON INDIAN FIRMS’ PERFORMANCE

The purpose of this paper is to examine the effect of cross-border M&As on Indian firms’ performance. It also mentions the literature review about M&As background and existing findings and methodology. In order to evaluate the effect, this paper uses the dataset including 151,141 observations of Indian companies in the period 1988-2009. The accounting-based data methodology is used in this research. The determinants for analyzing the effect of cross-border M&As are the effect of size of company, age, market share, leverage and M&As status on PBDIT (profit before depreciation, interest and tax) and PBIT (profit before interest and tax). All the results show that the most of factors bring the positive impacts on profitability except leverage. The results also demonstrate that companies which are involved in cross-border M&As have a higher profitability than non-cross-border M&As company. Although there have some limitations of this project in sample size of observations and methodology, this research still contribute some helpful implications about the effect of cross-border M&As in Indian companies. That is also a background step to carry out this project in the future to improve the above limitations and expand in a larger size and combined methodology

Developing Rural Tourism with the Participation of Related Parties in Bac Kan Province

Tourism development policy will pay attention to stakeholders, especially the people, who play an important role. However, in reality, when people participate in rural tourism development, they are not equipped with basic knowledge and skills in managing and serving tourists. Because the benefits between stakeholders are still not clear, the participation of people in rural tourism development is currently only passive. Active participation need to be directed from the Government and local authorities because the concept that rural tourism development is not only about creating economic benefits but also associated with conservation and preservation, together with keeping and promoting cultural - historical values in rural areas

How scientific research changes the Vietnamese higher education landscape: Evidence from social sciences and humanities between 2008 and 2019

Background: In the context of globalization, Vietnamese universities, whose primary function is teaching, there is a need to improve research performance. Methods: Based on SSHPA data, an exclusive database of Vietnamese social sciences and humanities researchers’ productivity, between 2008 and 2019 period, this study analyzes the research output of Vietnamese universities in the field of social sciences and humanities. Results: Vietnamese universities have been steadily producing a high volume of publications in the 2008-2019 period, with a peak of 598 articles in 2019. Moreover, many private universities and institutions are also joining the publication race, pushing competitiveness in the country. Conclusions: Solutions to improve both quantity and quality of Vietnamese universities’ research practice in the context of the industrial revolution 4.0 could be applying international criteria in Vietnamese higher education, developing scientific and critical thinking for general and STEM education, and promoting science communication

An improved method for lateral surface development of a circular truncated cone using vertical projection and its applications

In the field of mechanical engineering, particularly within the automotive, shipbuilding the utilization of metal sheets to create intersecting componentsis of great importance. However, the precise development of the circular surfaces that intersect with the circular truncated conical surface poses a critical challenge. It is essential to establish the intersection and accurately represent it on engineering drawings. This paper aims to overcome the limitations of existing approximate methods for the 2D development of circular truncated conical surfaces. This research offers a comprehensive solution for the accurate development of circular truncated cones, thereby enhancing precision and efficiency in engineering designs within industries such as automotive, shipbuilding, and pipeline engineering. By providing a quick and versatile development method based solely on vertical projection, contribute to the advancement of practical applications in these industries

Effect of plant growth regulators on growth and lipid accumulation of microalgal Haematococcus pluvialis Flotow in two-stage culture

Haematococcus pluvialis cells were cultured in aerated liquid Bold’s Basal medium in two-stage (initial stage during in 7 weeks for increased biomass growth and second stage during in 3 weeks for increased lipid accumulation) with different volumes 250 mL, 10 L, and 1,000 L. With a volume of 250 mL, the medium was supplied with benzyl adenine (BA), indole-3-acetic acid (IAA) or gibberellic acid (GA3) at concentration from 0.1 - 0.2 mg/L in initial stage and IAA or GA3 at concentration from 0.1 - 0.2 mg/L in second stage. After 10 weeks of culture, results showed that supplement of 0.1 mg/L BA in initial stage and 0.125 mg/L IAA in second stage increased cell density, and microalgal cells had green color with a spherical shape. On the contrary, supplement of 0.15 mg/L IAA in initial stage and 0.175 mg/L GA3 in second stage increased lipid accumulation, and microalgal cells had red color with a spherical shape. With a volume of 10 L, the medium was supplied with 0.1 mg/L BA in initial stage, and treated with separation or combination from 2 - 3 of these factors (nitrogen starvation, 0.5% NaCl, 4.98 mg/L FeSO4) were applied in second stage. The result showed that the cultures was treated with nitrogen starvation increased dry biomass and biofuel, but treated with 4.98 mg/L FeSO4 only increased biofuel. With a volume of 1,000 L, microalgal cells were cultured in BB liquid medium in initial stage, and treated with 4.98 mg/L FeSO4 increased fresh 78.67 mg/mL and dry biomass 2.05 mg/L and total lipid content 28.24 %/ DW
