A microwave technique for measuring respiratory movements of man and animal is described. The noncontacting based on the scattering continuous wave radiation. Preliminary results are shown both man, indicating usefulness procedure.
2-Aminothiazole (1) was discovered as a novel Src family kinase inhibitor template through screening of our internal compound collection. Optimization successive structure−activity relationship iterations identified analogs 2 (Dasatinib, BMS-354825) and 12m pan-Src inhibitors with nanomolar to subnanomolar potencies in biochemical cellular assays. Molecular modeling used construct putative binding model for Lck inhibition by this class compounds. The framework key hydrogen-bond interactions...
A microwave technique for recording apexcardiograms is reported. The based on detecting changes in the reflected microwaves caused by movement of chest wall response to left-ventricle activity. Results show that useful delineating fine structures precordial movement.
The cataractogenic effects of near-zone 2450-MHz radiation in rabbits are presented. power deposition pattern inside the eyes and head has been determined using a thermocouple technique. It was found that peak absorption 0.92 W/kg occurred between lens eye retina for each milliwatt/square centimeter incident. Time power-density studies indicated threshold 150-mW/cm2 incident, or 138-W/kg behind 100 min. time decreased with increasing density. Agreement vivo intraocular temperature...

Because blood loss attributable to laboratory testing is the primary cause of anemia among preterm infants during first weeks life, we quantified lost phlebotomy overdraw, ie, excess that might be avoided. We hypothesized overdraw in requested by hospital was a common occurrence, clinical factors associated with excessive would identified, and some these are potentially correctable. DESIGN, OUTCOME MEASURES, AND ANALYSIS: Blood samples drawn for purposes from neonates cared our 2 neonatal...
The IEEE Standards Association recently formally approved a new C95.1 "Standard for Safety Levels with Respect to Human Exposure Radio Frequency Electromagnetic Fields, 3 kHz 300 GHz." Official publication of the standard by was expected late 2005, or soon thereafter. contains some features current ICNIRP guidelines, but it also includes number differences. is not identical even frequencies used in cellular mobile communications and wireless devices systems. Moreover, newly departs major...
Abstract Purpose To present and discuss numerical calculations of the specific absorption rate (SAR) temperature in comparison to regulatory limits. While it is possible monitor whole‐body or whole‐head average SAR and/or core body during MRI practice, this not generally true for local values temperatures throughout body. methods calculation are constantly being refined, interpreting results these light limits also warrant discussion. Materials Methods Numerical human head a volume coil at...
The induced fields and the associated power deposition in mail exposed to HF electromagnetic (EM) have been investigated theoretically using spherical models. electric inside model either plane wave or near can be described adequately by a combination of quasi-static magnetic induction solutions. It is shown that for field impedances less than 1200/spl pi//spl Omega/ magnetically energy absorption predominates. Therefore, H must measured obtain any estimate hazards due exposure. For 70-kg...
A search for structurally diversified Tyk2 JH2 ligands from 6 (BMS-986165), a pyridazine carboxamide-derived ligand as clinical inhibitor currently in late development the treatment of psoriasis, began with survey six-membered heteroaryl groups place N-methyl triazolyl moiety 6. The X-ray co-crystal structure an early lead (12) revealed potential new binding pocket. Exploration pocket resulted two frontrunners candidate. hydrogen bonding interaction Thr599 was achieved tertiary amide moiety,...
Nonreceptor protein tyrosine kinases including Lck, ZAP-70, and Itk play essential roles in T-cell receptor (TCR) signaling. Gene knockout studies have revealed that mice lacking these individual exhibit various degrees of immunodeficiency; however, highly selective small molecule inhibitors as potential immunosuppressive agents not been identified. Here we discovered two novel compounds, BMS-488516 BMS-509744, potently selectively inhibit kinase activity. The compounds reduce TCR-induced...
This paper presents a new microwave antenna design with improved heating at the tip for interstitial hyperthermia and thermocoagulation. Temperature distribution patterns surrounding conventional insulated sleeved coaxial slot radiator are measured in saline phantom under transient steady-state conditions. The provides an temperature over active region of radiator. In contrast to cold zone maximal (sixfold greater) power deposition its tip.
We have studied the interaction of microwaves with blood-brain barrier in Wistar rats. Indwelling catheters were placed femoral vein. Evans blue isotonic saline was used as a visual indicator permeation. Irradiation pulsed 2450-MHz for 20 min at average power densities 0.5 to 2600 mW/cm/sup 2/, which resulted specific absorption rages (SARs) 0.04 200 mW/g brain, did not produce staining, except regions that normally are highly permeable. When incident density increased 3000 2/ (SAR 240...
When a human subject is exposed to pulsed microwave radiation, an audible sound occurs which appears originate from within or immediately behind the head. Laboratory studies have also indicated that evoked auditory activities may be recorded cats, chinchillas, and guinea pigs. Using spherical model of head, this paper analyzes process by energy cause observed effect. The problem formulated in terms thermoelasticity theory absorbed represents volume heat source depends on both space time....
Recent interest and current optimism regarding battery-charging wireless power-transfer technology are driven by the ubiquity of cell phones other mobile communication devices. In some ways, this is to make a dream come true: truly or portable device, completely free from being tethered in any way. The concept power transfer not new, even for charging batteries. Cellular service users customers may be annoyed do want bothered with having plug device into an electrical outlet. If true - as...
