Micromethod for MN antigen grouping of dried bloodstains

A micromethod based on the absorption elution technique was shown to be applicable to the detection of M and N blood groups of dried bloodstains on cotton cloth. Each antigen M and N was tested using two different types of antisera. Two hundred different bloodstains, stored up to six months, were analyzed. Conclusive results were obtained for M typing on 2.5-mm-long bloodstained threads. For N typing, some cross-reactivity of homozygous M stains with anti-N sera was observed. This may be explained by the structure of the M and N antigens on the red cell membrane.     

Proposed: a comprehensive health care system for the poor.

More than half the poor are not covered by Medicaid, the program designed to serve them. Louise Russell outlines a program that would make health care available to all of the poor.     

Identification of mechanical asphyxiation in cases of attempted masking of the homicide

Five homicides are described that had remained unexplained as to the causes of death after gross pathology. Although general signs of asphyxiation were present, they were lacking injuries specific of strangulation or oro-nasal occlusion. The diagnoses of asphyxiation were established by microscopical investigation of the lung and confirmed by subsequent police inquiries. An oro-nasal occlusion was involved in three cases, a strangulation or an oro-nasal occlusion, in another case. The victims were young and healthy. Toxicological investigations remained negative in four cases; one victim was anaesthetized by bromazepam and ether and had a blood alcohol concentration of 80 mg/100 ml. Lung histology and electron microscopy revealed acute emphysema, the development of a haemorrhagic-dysoric syndrome and a microembolism syndrome. With regard to the haemorrhagic-dysoric syndrome, the development of alveolar-interstitial edema is particularly important. This finding may also be diagnosed by light microscopy in semi-thin sections. It is emphasized that the combined action of several pathomechanisms is responsible for the rapid manifestation of the pulmonary lesions. Especially, the haemorrhagic-dysoric syndrome is brought about by the combined action of inspiratory intrapulmonary vacuum and raised intracapillary pressure. The complex pattern allows to compile the diagnosis of mechanical asphyxia even if there is no corresponding injury.     

The examination of vaginally inserted plastic tampon applicators for genetic markers and evidence of prior sexual intercourse

Vaginally inserted plastic tampon applicators were obtained from 42 female volunteers. The applicators were examined for the presence of ABH blood group substances, phosphoglucomutase (PGM), amylase, acid phosphatase, P30, and intact spermatozoa. Each applicator was accompanied by a control blood sample, a saliva specimen, a brief sexual and menstrual history, and method of birth control of the donor. Eight of the male sexual partners of the donors submitted blood and saliva samples. One male sexual partner submitted only a saliva sample. ABH blood group substances corresponding to the donor were recovered from 36 of the 42 applicators. The remaining 6 applicators revealed a combination of the donor's and sexual partner's ABH substances. The female's PGM type was recovered from 34 of the applicators. The remaining 8 applicators failed to show PGM activity. Of the applicators, 15 indicated evidence of prior sexual intercourse by the detection of ABH substances not consistent with the applicator donor (6 samples), high levels of acid phosphatase (11 samples), or recovery of spermatozoa (8 samples) or some combination of these. All applicator samples failed to show the presence of either P30 activity or PGM factors foreign to the female.     

Providing service--or aiding and abetting discrimination?

Even though federal antidiscrimination laws do not include third-party liability, a number of states now have statutes containing aiding-and-abetting provisions that may provide a basis for causes of action. For instance, in a recent decision, the Colorado Supreme Court held that a third-party insurance company will be held liable along with the employer for providing health insurance coverage that does not cover normal pregnancy expenses. Similarly, cases involving newspapers have shown that newspaper classifieds may occasion liability solely to the newspaper, and not the advertiser, even absent intent. The author provides a full discussion of such issues as standard of proof and exactly who is liable and offers solutions to these new liability problems.     

An evolving technology-transfer system in an R&D consortium: The EPRI approach

The Electric Power Research Institute (EPRI) is a consortium of utility companies whose existence depends on member perceptions that valuable technologies and information have been developed and transferred. This paper outlines eight issues that EPRI, after 17 years of operation had determined to be critical in transferring technology: [1] establishing a perception of value received, [2] creating a sense of full partnership, [3] balancing the R&D portfolio with projects for different members, [4] packaging results for easy understanding and use, [5] reducing information overload by using targeted media, [6] assuring that members have the needed infrastructure to receive and process transfer, [7] integrating EPRI's R&D program with those of the members, and [8] monitoring impact to be sure that value is being received.     

THE EFFECT OF LONGITUDINAL ARREST PATTERNS ON THE DEVELOPMENT OF ROBBERY TRENDS AT THE NEIGHBORHOOD LEVEL *

Although the current resurgence of ecological deterrence research has addressed many of the methodological and theoretical problems of earlier studies, the question concerning the appropriate level of aggregation for such models has not been resolved. In this paper, we argue that there is strong evidence in the criminological literature that the neighborhood is the most meaningful level of aggregation for such studies. However, in an analysis of robbery incidents and arrests over 100 weeks in five Oklahoma City neighborhoods we did not find any significant support for the deterrent effect of arrests on subsequent illegal behavior. We propose that the lack of such a relationship reflects periods of short-term equilibrium in the local community, during which the levels of crime and arrests are relatively stabilized.     

Suicide by nitrous oxide poisoning

Fatal nitrous oxide poisoning usually occurs accidentally during the administration of general anesthesia. It seldom occurs during autoerotic behavior or in acute drug abuse. We report an unusual case of a health professional who committed suicide by inhaling nitrous oxide.     

Mass spectrometry as an aid in the detection and identification of piperidyl benzilates and related glycolates.

On the basis of the data presented above the following conclusions may be drawn. 1. The molecular ion peaks of most of the compounds examined are relatively weak but usually easily discernible to permit molecular weight determination. 2. The mass spectra of benzilate esters exhibit a relatively intense peak at m/e 183, and monitoring of this ion can serve as a means for preliminary screening for the presence of this type of a system. 3. Related esters exhibit a similar type of fragmentation resulting in a fragment ion analogous to m/e 183 but shifted by the appropriate number of mass units according to the substituents present. 4. Cleavage of the piperidine ring-ester oxygen bond in 3 and 4-substituted isomers is followed by selective losses of hydrogen radicals to produce ions of type e, f, and g as indicated above. It is significant that in a related piperidine ring system (methylphenidate) substituted in the 2 position, the same type of cleavage results in no further hydrogen losses [16] because of charge stabilization from the ring nitrogen (ion j, Fig. 17) [17]. In other words, the tendency to form a conjugated ion following initial bond cleavage can serve as a means for identifying the position of substitution on the ring and for distinguishing positional isomers.
