A stable L-form of Streptococcus faecalis (T(53)) was transferred in media containing decreasing concentrations of sucrose until it grew in medium without added osmotic stabilizer. This L-form (designated T(53I)) was compared with T(53) from which it was derived. The survival of these two L-forms suspended at different osmolalities showed that maximal survival for T(53I) was 350 to 400 milliosm...
In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
Cerebrospinal fluid (CSF) is crucial for normal function and mechanical protection of the CNS. The choroid plexus epithelium (CPe) is primarily responsible for secreting CSF and regulating its composition by mechanisms currently not fully understood. Previously, the heteromeric KCNQ1-KCNE2 K(+) channel was functionally linked to epithelial processes including gastric acid secretion and thyroid ...
The subthreshold, voltage-gated potassium channel of skeletal muscle is shown to contain MinK-related peptide 2 (MiRP2) and the pore-forming subunit Kv3.4. MiRP2-Kv3.4 channels differ from Kv3.4 channels in unitary conductance, voltage-dependent activation, recovery from inactivation, steady-state open probability, and block by a peptide toxin. Thus, MiRP2-Kv3.4 channels set resting membrane po...
Organic acids play an important role in improving the bioavailability of soil nutrients. The objectives of this study were to determine the effect of oxalic acid on the release of soluble, exchangeable and non-exchangeable forms of K from micaceous minerals and potassium feldspars, and also to investigate the trend of K release by time. A laboratory study was carried out using a completely rand...
Background and purpose: There are controversies on the association between electrolytes and Coronavirus disease 2019 (COVID-19) and its severity. Studies on these issues may help in resolving ambiguities. The purpose of this study was to assess the association between electrolyte indices and being infected with COVID-19 and developing severe symptoms using a meta-analysis. Materials and method...
Totally water soluble compositions of NPK-fertilizers containing microelements in chelate form were developed. The methods synthesis complexes the most important optimized, structure obtained compounds was confirmed by X-ray phase analysis, IR-spectroscopy and elemental analysis. Obtained fertilizers are perspective for incorporation on technical chlorophobic fruit-berry crops using different a...
The impact that nitrogen (N), phosphorus (P), and potassium (K) application rates on the sulfur (S) fractions in leaves and fruits of greenhouse-grown cucumbers plants (Cucumis sativus L. cv. Brunex) are presented. The treatments were as follows: N (N11⁄4 5 g NO3NH4=m, N21⁄4 10 g NO3NH4=m, N31⁄4 20 g NO3NH4=m , N41⁄4 40 g NO3NH4=m), two levels of P (P11⁄4 8 g H3PO4=m 2 and P21⁄4 16 g H3PO4=m), ...
