Open AccessIn vivo dynamics of pro-inflammatory factors, mucins, and polymorph nuclear neutrophils in the bovine oviduct during the follicular and luteal phase
Dynamic functional changes in the oviductal microenvironment are the prerequisite for the establishment of pregnancy. The objective of this study was to gain the first insights into oestrous cycle-dependent dy...

An unusual side chain C-C cleavage at the MeBmt amino acid in cyclosporin A
The mixture of products obtained by alkaline treatment of cyclosporin A was analyzed by HPLC-continuous-flow-FAB/MS. The changes involve the atypical amino acid (4R)-4-((E)-2-butenyl)-4,N-dimethyl-L-threonine (Me...

Lack of effect of baclofen on substance P and somatostatin release from the spinal cord in vitro
High concentrations of K+ increase the release of substance P (SP) and somatostatin (SRIF) from superfused slices of rat spinal cord. This increase is Ca-dependent. Baclofen (100–500 μM) does not significantly al...

High K+-induced release of somatostatin from the cortical preparation of rat brain
Release of endogenous somatostatin (SRIF) from the rat cerebral cortical slices incubated in Krebs-bicarbonate buffer was increased from the basal rate of 3.4±0.6% of the total SRIF content in 15 min at [K+]o=5.6...

Temperature dependent EPR of octahedral S-state ions in garnets
Temperature dependence of EPR of the octahedral Fe3+ and Mn2+ ions in four different garnets is studied between 77 K and the room temperature. The observed change of the spin hamiltonian parametersB ...

Intraventricular Met5-enkephalin causes unexpected lowering of pain threshold and narcotic withdrawal signs in rats
PEPTIDES with opiate properties have been demonstrated in brain1–3 and pituitary4–7. Goldstein8 has postulated that sustained low-intensity pain might promote the central mobilisation of endogenous opioid as part...

Nonparallel changes in brain monoamines of pyridoxine-deficient growing rats
The effects of a large number of neurotropic drugs have been attributed to changes in the metabolism of 5-hydroxytryptamine. The aromatic amino acid decarboxylase considered to decarboxylate both dihydroxyphen...

Supertransferred hyperfine structure in EPR of V4+ ion in Ca3In2Ge3O12 garnet
Interaction of an unpaired electron of the tetrahedral V4+ ion in Ca3In2Ge3O12 garnet with the four nearest In nuclei gives rise to clearly resolved structure of EPR spectra. We report the observation and analysi...

EPR line-width intensity of V4+ ion in NaCa2Mg2V3O12 garnet
We report on measurements of width and intensity of EPR lines corresponding to V4+ ion, which is located at the tetrahedral site of NaCa2Mg2V3O12 garnet. At 77 K the strange dependence of line-width on nuclear qu...
