As products of genome mining, the stereochemical assignment macrolide antibiotics stambomycins A–D has been made on basis sequence analysis associated polyketide synthase, aside from...

Aim. To evaluate strength of magnesium ion complexes with levofloxacin and moxifloxacin. Materials methods . Complexation levofloxacin, moxifloxacin, reference ligands (ethylenediaminetetraacetate (EDTA), sodium citrate, glycine) ions in the range from 0.0 to 1.0 mmol / l was studied. The technique developed by authors (patent RU 2680519 C1) used measure rate a model formation reaction phosphat...

1. We studied the effect of varying excitatory and inhibitory drive on the N-methyl-D-aspartate (NMDA) receptor-mediated component of the visual responses of neurons in the cat dorsal lateral geniculate nucleus (dLGN) by varying the contrast and size of stimuli presented to the receptive fields of these cells. 2. Cells were classified as either on- or off-center, X or Y, and lagged or nonlagged...

Tulisan ini mengkaji kualitas parameter akustik, dari lima ruangan di Univeristas XYZ, yang terbagi ke dalam tiga klaster fungsi (studio, ruang rapat, dan kelas). Rekaman suara sumber impulsif dianalisis dengan menggunakan perangkat lunak REW untuk menghasilkan reverberation time RT60 speech clarity C50 dapat digunakan memeringkat kelima tersebut. Analisis menunjukkan adanya korelasi erat antar...

Over the course of evolution, nature continually discovers new small molecules through the alteration of biosynthetic enzymes and pathways by mutation and gene transfer. Hundreds of these natural products have proven indispensable to medicine, culture, and technology, greatly contributing to increases in the length and quality of human lives. Chemists have found that the “chemical space” surrou...

Aim: To evaluate the cardiovascular effect of carvacrol treatment in a D(+)galactose accelerated aging model, investigating effects on vascular reactivity, oxidative stress, and systolic blood pressure (SBP).
 Methodology: Eight-week-old male Wistar rats (Rattus norvegicus) were used for oral eight weeks. Organ baths reactivity studies (FEN, ACh, NPS), fluorescence microscopy to detect rea...

This paper considers the nonparametric identification and estimation of the average effect of a dummy endogenous variable in nonseparable models. The analysis includes the case of a dummy endogenous variable in a discrete choice model as a special case. This paper establishes conditions under which it is possible to identify and consistently estimate the average effect of the dummy endogenous v...
