A computer-aided semen analysis system was used for the objective assessment of hamster spermatozoa during epididymal maturation. The caput epididymal spermatozoa were extremely sluggish, achieved very little progression, and the three velocity parameters, namely curvilinear velocity (VCL), progressive velocity (VSL), and path velocity (VAP), were low. These spermatozoa during progressive ...

OBJECTIVE: To evaluate the effects of continued drug use and other cofactors on progression to AIDS among HIV-infected injecting drug users. DESIGN: A prospective study. SETTING: The Muirhouse Medical Group in Edinburgh, Scotland, UK. SUBJECTS: A total of 156 HIV-infected injecting drug users. MAIN OUTCOME MEASURES: Progression to AIDS and ...

Standardized uptake values (SUVs) are widely used to measure 18F-fluorodeoxyglucose (FDG) uptake in various tumors. It has been reported that normalization of FDG uptake for patient body weight (SUVbw) overestimates FDG uptake in heavy patients, as their fraction of body fat (with low FDG uptake) is often increased. The objective ...

Psychological intimacy develops between a speaker and a listener. Depending on how individuals fulfill these roles, intimacy may occur or be precluded. Intimacy quickly creates a bond and, if repeated, enhances psychological function. Psychological intimacy is the glue of all important relationships, including professional ones. It also is a powerful ...

The progress of the discussion about the 'indicators of humanhood' is reviewed, along with several associated problems. It is argued that a more serious problem is posed by social attitudes about mental handicap. The author concludes that an uncritical use of criteria of humanhood may simply reinforce a morally unjustifiable ...

An unusual case of Progressive Multifocal Leukoencephalopathy (PML) in a Haitian man with AIDS is reported. The lesions involving both white and gray matter are described radiologically and at post-mortem. The implications regarding neuroradiological differential diagnosis in AIDS as well as PML virulence in this type of patient are discussed.

The problem of the relationship between obsession and delusion is dealt with from descriptive, anthropoanalytical and purely phenomenological points of view. The main differential aspects are focused. The phenomenological concept of the progressive fading of the 'feeling of Ego activity' is proposed as the functional bias at the basis of ...

It is difficult to imagine a more perennially vexing topic to philosophers, scientists, and physicians than the mind-body problem. Recent literature bears out its continued vital interest for psychiatrists. This article briefly recapitulates the major perspectives on the problem, examines the relationship of meaning and mind to psychosocial and biological ...

We studied three patients with acquired immune deficiency syndrome (AIDS) and progressive polyradiculopathy. Postmortem examination of one patient disclosed extensive necrosis, inflammatory infiltrates, and focal vasculitis of spinal roots. Typical cytomegaloviral (CMV), intranuclear, and intracytoplasmic inclusions were noted within enlarged endoneurial and endothelial cells. Progressive polyradiculopathy is an unusual complication ...

The concept of the radiological depth is central to all algorithms which calculate radiation dose in a heterogeneous medium. For a discrete heterogeneous medium, consisting of regions of inhomogeneity, the radiological depth is usually presented as the sum over segments of the product of the segment length and the inhomogeneity ...

Since the discovery of the satiety effect of CCK in 1973, progress has been made and problems have been encountered. The progress has included the accumulation of strong, indirect evidence that exogenous CCK acts in the abdomen to activate vagal afferent fibers and that exogenous CCK may be useful in ...

The extraction of some metal values, e.g., uranium or copper, may be accomplished by using solutions to remove metals from ore bodies without practicing conventional mining. This process is referred to as in situ leaching and has been used industrially to recover uranium. The growth of microbial populations during in ...

A review of recent progress in the investigation of the following two problems is given: (a) the origin of actyl groups in the acetylcoenzyme A which is used for the synthesis of actylcholine in mammalian nerve cells; (b) the role of acetylcoenzyme A in the control of acetylcholine synthesis. The ...

Because pneumothorax may impair ventilation, it should be included in the differential diagnosis whenever ventilating problems are encountered during intraoperative procedures. Since pneumothorax is not an expected complication following atraumatic removal of tracheobronchial foreign bodies, it may not be considered if ventilation problems arise. When a foreign body has one ...

Coprolites were collected with the aid of a rectosigmoidoscope from a naturally mummified body of a child. The body dates from 3.490 +/- 120 to 430 +/- 70 BP and was found in the State of Minas Gerais, Brazil. The coprolites were rehydrated with a trisodium phosphate solution and concentrated ...

51 suicides in a rural community of Northern Karnataka were studied for incidence, age and sex distribution, methods adopted for suicides, and causes of suicides. Suicides in rural area did not show any difference from urban suicide pattern.

Problem-oriented style progress notes were implemented in a skilled nursing facility where problem-oriented medical records were not in use. The problem-oriented note consists of subjective information, objective information, analysis or assessment of the problems, and plan for treatment, and is called a SOAP note. Six physical and occupational therapists used ...

All psychologic phenomena occur in consciousness. However, "consciousness" has two meanings: the faculty and the content of awareness. Traditional psychologies have largely concerned themselves with the content, neglecting the problem of the faculty, thus, limiting our understanding of human psyche. Study of meditation is a viable approach to the exploration ...

Recent work in neurophysiology has begun to close the paradigmatic gap between neurophysiology and the psychology of embodied behavior and movement. The present paper surveys these developments, traces the origins of the split between neurophysiology and neuropsychology and suggests that recent work by Pribram may provide a link between the ...

A completely rigorous study of the high frequency asymptotics for the scattering matrix in the exterior of convex bodies is developed. These results are then applied to a variety of inverse problems for convex bodies.

It is concluded that progress in medicine has been maintained at such a rapid pace that the delivery system has had difficulty in keeping up. This has been excellently demonstrated by the progress in the category of vascular surgery. Achievements have placed added demands on available trained personnel, materiel, and ...
