The non-abelian tensor product of groups which has its origins in algebraic K-theory as well as inhomotopy theory, was introduced by Brown and Loday in 1987. Group theoretical aspects of non-abelian tensor products have been studied extensively. In particular, some studies focused on the relationship between the exponent of a group and exponent of its tensor square. On the other hand, com...

Abstract It is known that the starlikeness plays a central role in complex analysis, similarly as convexity functional analysis. However, if we consider biholomorphisms between domains $${\mathbb {C}}^{n},$$ Cn, apa...

copper and nickel are an essential micronutrient for plants, playing an important role in maintaining plants' natural metabolism and growth, but in excess both heavy metal are also a proven inhibitor of various physiological functions. in this study maize (zea mays l.) plants grown in hydroponic culture were treated with 0, 50 and 100 μm cuso4 and 0, 100 and 200 μm niso4 . growth parameter...

Background: COVID-19 is a disease that attacks the respiratory system and highly contagious, so cases of spread are increasing every day. The increase in cannot be predicted accurately, resulting shortage services, facilities medical personnel. This number will always if community not vigilant actively reduces rate adding confirmed cases. Therefore, public awareness vigilance need to increased ...

Na,K-ATPase activity, Na,K-ATPase alpha- and beta-subunit mRNA abundance (mRNA alpha and mRNA beta), and gene transcription rates were determined in kidney cortex and liver of hypothyroid and triiodothyronine (T3)-treated rats. In hypothyroid rats, Na,K-ATPase activity (expressed per unit of DNA) was 3.6-fold greater in kidney cortex than liver, and the abundance of mRNA alpha and mRNA beta in ...

Tigecycline is one of the few therapeutic options for treating infections caused by some multi-drug resistant pathogens, such as Klebsiella pneumoniae. However, tigecycline-resistant K. pneumoniae has been discovered recently in China. From 2009 to 2013, nine tigecycline-resistant K. pneumoniae isolates were identified in our hospital. Six of nine strains were identified before using tigecyclin...

Dihydrofolate reductase (EC 1.5.1.3) is a key enzyme in the folate biosynthetic pathway. Information regarding key residues in the dihydrofolate-binding site of Mycobacterium avium dihydrofolate reductase is lacking. On the basis of previous information, Asp31 and Leu32 were selected as residues that are potentially important in interactions with dihydrofolate and antifolates (e.g. trimethoprim...
