Spatially resolved measurements of the argon excimer, , were performed in the effluent of a cold atmospheric plasma jet (CAPJ), the so called kINPen-sci, using cavity ringdown spectroscopy. The spatial distribution of the density of could be distinguished into two distinct populations: a Gaussian and a toroidally shaped distribution. The production mechanisms of these populations seem to differ.

Background: The anatomy of the hand makes it uniquely sensitive to complications after bacterial infection. The causative organism has been implicated as a predictor of complications after surgery. We hypothesize that bacterial etiology is associated with different operation and reoperation rates in patients with flexor tenosynovitis.

Medical gas plasma is an experimental technology for anticancer therapy. Here, partial gas ionization yielded reactive oxygen and nitrogen species, placing the technique at the heart of applied redox biomedicine. Especially with the gas plasma jet kINPen, anti-tumor efficacy was demonstrated.

As part of a phase Ib clinical trial to determine the tolerability and safety of the highly specific acetylcholinesterase (AChE) inhibitor huperzine A, twelve (12) healthy elderly individuals received an escalating dose regimen of huperzine A (100, 200, 300, and 400 microg doses, twice daily for a week at each dose), with three (3) individuals as controls receiving a placebo. Using the WRAIR whole blood cholinesterase assay, red blood cell AChE and plasma butyrylcholinesterase (BChE) were measured in unprocessed whole blood samples from the volunteers following each dose, and then for up to 48h following the final and highest (400 microg) dose to monitor the profile of inhibition and recovery of AChE. Significant inhibition of AChE was observed, ranging from 30-40% after 100 microg to >50% at 400 microg, and peaking 1.

Coherent anti-Stokes Raman spectroscopy (CARS) has been used to obtain radial temperature profiles in an axisymmetric methane diffusion flame. Temperatures were obtained from analysis of background-free nitrogen Q- and O-branch spectra. The spectra were analyzed with a nonlinear least-squares CARS fitting program and compared to measurements from radiation- and conduction-corrected thermocouples.

Rheumatoid factor (RF)-like substances and heterophil agglutinins (HA) were induced in rabbits by infection with a strain of Trypanosoma equiperdum. Infection with a T. gambiense strain produced HA, but no RF.

The cure of Trypanosoma equiperdum infected Mice obtained after treatment with an association of electromagnetic waves and a magnetic field is probably linked with the immune state of the host. A severe depression of the immune system suppresses the ability of the animals to eliminate the parasites after physical stimulation.

Incomplete information on factors contributing to apparent protein quality and to value of food products as sources of protein and how these factors interact necessitate the use of bioassay procedures. Ideally bioassay procedures should be done using the animal species for which the protein is intended. Practical considerations dictate the use of small animal bioassay rather than human bioassays for routine use in protein product evaluation.

Substantial genetic, variability for grain protein content in wheat has been identified. In appropriate combinations known genes can increase protein content of wheat grain by 5 percentage points. Productive high protein experimental lines with good agronomic traits and satisfactory processing attributes have been identified.

Different evolutions of experimental trypanosomiasis are observed in Mice kept in a permanent 35 degrees C environment. Evolution depends on the individuality or the strain of the host animal. An experimental factor influence on the host mechanism defense rather than on the parasite multiplication rate is shown.

The remarkable efficiency of the physical treatment using such an association enables the mice to handle an infection otherwise lethal in a few days. The recovery is due to a very strong stimulation of defense system of the host-animal particularly those related to the immune responses. This effect can be obtained in spite of the depression of the immunological defenses prior to the infection.

The multiplication of the trypanosomes in a "diffusion chamber" is great during the first 4 or 5 days following implantation. The reduction in numbers of parasites on the following days depends largely on the humoral antibodies resulting from the immune response.

Rheumatoid factor-like substances were induced in rabbits by infection with . There was a certain parallelism with the phenomena described earlier with infections in man. The anti-IgG globulins were IgM with a preference for heterologous (human) IgG in the latex fixation test.
