Invasive microwave antenna array for hyperthermia and brachytherapy

A microwave hyperthermia apparatus that can be inserted into the body which includes a hollow central tube for the insertion of radioactive therapy sources. The use of a coaxial transmission line impedance transformation along the insertable portion of the coaxial cable enables a reduction in the characteristic impedance by increasing the outer diameter of the inner coaxial conductor so that the center conductor can be a metal tube. If the ratio of the outer coaxial conductor diameter vs. the inner coaxial conductor is decreased, the characteristic impedance of the transmission line is lowered. This enables the inner conductor diameter to increase sufficiently to make the central hollow opening large enough to receive standard radioactive sources therein. This provides for a good impedance match that improves microwave energy efficiency while at the same time permitting a large hollow center opening. The combination of the microwave antenna device and brachytherapy sources provides for enhanced effectiveness when the two treatments are delivered simultaneously or in close time proximity to each other.

Channel estimation and/or equalization using repeated adaptation

A novel approach of repeated adaptation is provided that can be applied to either one or both of channel estimation and / or equalization. From an incoming data packet that includes data and a training sequence, a modified data packet is generated that includes the data, the training sequence, and at least one additional copy of the training sequence. From the format of this modified data packet, the same training sequence can be used over and over again a desired number of times to perform channel estimation and subsequent calculation of equalizer tap coefficients. Alternatively, the same training sequence can be used over and over again a desired number of times to converge the equalizer coefficient taps directly without doing any preliminary channel estimation. Generally, either of these approaches can be characterized as a cyclic adaptation operation that provides improved performance without incurring any reduction in throughput of the communication channel.

Antimicrobial amino acid sequences derived from alpha-melanocyte-stimulating hormone

The presence of the ancient anti-inflammatory peptide α-melanocyte stimulating hormone (α-MSH [1-13], SYSMEHFRWGKPV) in barrier organs such as gut and skin suggests a role in the nonspecific (innate) host defense system. α-MSH and other amino acid sequences derived from α-MSH were determined to have antimicrobial influences, including against two major and representative cutaneous and mucosal pathogens: Staphylococcus aureus and Candida albicans. C-MSH peptides had antimicrobial effects against S. aureus and significantly reversed the enhancing effect of urokinase on S. aureus colony formation. α-MSH and other amino acid sequences reduced C. albicans viability and germination. α-MSH peptides also enhanced C. albicans killing by human neutrophils. The antimicrobial agent is selected from the group consisting of one or more peptides including the amino acid sequence KPV, one or more peptides including the amino acid sequence MEHFRWG, or a biologically functional equivalent of any of the foregoing. The most effective of the peptides were those bearing the C-terminal amino acid sequence of α-MSH, i.e., α-MSH (1-13), (6-13), and (11-13). The α-MSH “core” sequence (4-10), important for melanotropic effects, was also effective but significantly less potent. Antimicrobial influences of α-MSH peptides could be mediated by their well-known capacity to increase cellular cAMP; this messenger was significantly augmented in peptide-treated yeast. α-MSH has potent anti-inflammatory effects and is expected to be useful for treatment of inflammation in human and veterinary disorders. Reduced killing of pathogens is a detrimental consequence of therapy with corticosteroids and nonsteroidal anti-inflammatory drugs during infection. Therefore, anti-inflammatory agents based on α-MSH peptides that do not reduce microbial killing, but rather enhance it, would be very useful. The antimicrobial effects of these α-MSH peptides occurred over a broad range of concentrations including the physiological (picomolar) range.

Differentiated tissue excitation in MRI

Selectively exciting bulk protons in certain tissue components, e.g. water, while suppressing the excitation of others, e.g. fat, can lead to images with better contrast for desired features. The invention provides binomial, off-resonance RF excitation pulses for differentiating tissue excitation that yields a larger fat suppression that prior art water excitation methods. Proper balancing of the frequency offset and the pulse duration with a relative phase offset between the pulses leads to large-bandwidth pass- and stopbands for water and fat, respectively. The pulses can be applied with short, or even zero, interpulse delay, leading to substantial time savings in the imaging sequence.
