OBJECTIVES Infertility is a worldwide health problem which affects approximately 15% of sexually active couples. One of the factors influencing the fertility is melatonin. Also, protection of oocytes and embryos from oxidative stress inducing chemicals in the culture medium is important. The aim of the present study was to investigate if melatonin could regulate hyaluronan synthase-2 (HAS2) and...

Plant growth regulators (PGRs) are exogenously applied chemicals that alter plant metabolism, cell division, cell enlargement, growth and development by regulating plant hormones or other biological signals. For example, some PGRs regulate stem elongation by inhibiting biosynthesis of gibberellins or through releasing ethylene. PGR effects are widely studied and reported on barley (Hordeum vulg...

In this editorial, we introduce our second issue, centred around the theme of “Virtual, physical, or somewhere in between”. We outline some challenges that PGR teachers have faced over past few years, as well increasing attention being paid to their innovative and important work. explore evolving nature journal discuss what would like see future issues.

Urbanization, generally across developing countries, is accelerating at an ever-increasing pace along with population growth. The growth of built-up space often disproportionate the rate, creating multiple stresses to environment and hindering sustainable development. To account for this disproportionality, SDG 11.3.1 indicator “Ratio land consumption rate (LCR) Population (PGR)” was developed ...

a highly sensitive differential pulse polarographic (dpp) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (viii) on the oxidation of pyrogallol red (pgr) by sodium bromate at ph 7.00 and 25.0 0.1 ? c. the reaction rate was monitored by measuring the differential pulse cathodic current of the oxidation product of pgr and bromate...

FloraMap is a specialized GIS program which was developed to map the predicted distribution, or areas of possible climatic adaptation, of organisms in the wild. The climate at the locations where individuals of a given taxon were observed is assumed to be representative of the environmental range of the organism. The climate at these locations is extracted from a set of interpolated climate gri...

The two commercially important apple rootstocks i.e., MM106 and B9 were micropropagated using a liquid culture system. Three different strengths of 0.8% agar solidified PGR free basal MS medium were first tested to optimize the culture media for both the rootstocks. Full strength medium (MS0) supported maximum in vitro growth, multiplication, rooting and survival under field conditions as oppos...

Available groundwater research work and data levels are very limited due to the wide territory of our country. Potential Groundwater resources need be calculated by basin implement Integrated Water Resources Management Plans. For this purpose, previously calculations were done twice in Orkhon River Basin. The last calculation was 10 years ago, therefore Plan needs redeveloped, using updated lev...

Purpose Hyperglycemic diets are a critical risk factor for diabetes and other chronic diseases; therefore, food innovation is encouraged. In this sense, starchy foods with better postprandial glycemic response (PGR) could contribute to disease prevention consumers. This study aims evaluate the effect of three biscuit formulations on indicators – in general, by sex their acceptability. Design/me...

Phalaenopsis amabilis (L.) Blume Orchid is one of the species in genus and are well-known as exotic beautiful white flowers. Besides that, there little continuity mass propagation that produce many standardized seedlings a relatively short period to satisfy market demand. This study was focusing on evaluating effect natural additives plant growth regulators (PGR). PGR used nutritional constitue...
