This study evaluated the self-reported patterns of handedness among a large subsample (n = 1612) of the gay/bisexual men comprising the Multicenter AIDS Cohort Study (MACS). There was a small but significant elevation in left-handedness among gay/bisexual men compared to available normative data. However, there were no differences within the ...

The problems associated with Gutierrez model (1986, Resp. Physiol. 63, 79-96) on O2 delivery to tissue are discussed. He has used a dimensionally incorrect function for the oxygen dissociation curve (ODC). The dimensionally correct function for the ODC has been used in the analysis and the correct results are given ...

A transmetatarsal pin was used as part of an Ilizarov apparatus to correct equinovarus deformity of a foot in a 7-year-old patient. The pin created synostosis between the metatarsal bones. The synostosis led to persistent flattening of the transverse arch of the foot, producing a painful gait. To avoid this ...

Attitudes toward victims of AIDS were conceptualized as serving three possible functions: a value-expressive function (e.g., stigmatization), an ego-defensive function (e.g., homosexual prejudice), or a knowledge function (e.g., victim derogation). These functions were evaluated by having a sample of U.S. undergraduates respond to a victim who had contracted AIDS by ...

In 1983, Lezak described executive functioning as the ability to engage in independent, purposeful, self-directive and self-serving behaviour. Self initiation, problem-solving and self-monitoring or regulation of behaviour are important components of executive functioning. This paper presents the results of efforts to improve executive functioning in three areas: problem solving, self-initiation ...

High level, upper extremity amputees have been observed to have problems affecting overall prosthetic function. These include: tendency of the Northwestern Ring to ride upward and difficulty with terminal device function above 90 degrees of elbow flexion. A simple modification of the control strap was tried to resolve these problems ...

It can be argued that all functional appliances are basically similar, using a family of common component parts. The components incorporated into a design should be chosen rationally, after consideration of the particular malocclusion to be treated. This article therefore explains functional appliances in terms of their components. It aims ...

The enhancement of the vestibulo-ocular reflex (VOR) gain in the eccentric rotation is mediated by the otolith organs. Functional recovery of the otolith-ocular reflex after deafferentation of the otolith organs was examined in squirrel monkeys, using the enhancement of the eccentric VOR gain as an indicator of the reflex. After ...

Lower extremity problems in the runner are common and often perplexing. Although many problems such as acute tendinitis and mild sprains can be treated with short periods of rest and nonsteroidal anti-inflammatory drugs, some will be chronic or recurrent in nature. These persistent problems can cause even a serious runner ...

Kernberg's writings on borderline pathology have greatly influenced the mental health world. More recently, Adler has emerged as another psychodynamic authority on this disorder. Adler challenges Kernberg with a different conceptual framework and posits a different core problem for borderline patients. Some writers have contrasted Kernberg's "conflict" theory with Adler's ...

The foot is the most common source of limb pain. The problems vary from simple to quite complex. An accurate diagnosis is dependent upon a thorough and detailed knowledge of anatomy and of what is available in the way of ancillary examination techniques. The correction of most foot problems requires ...

This article discusses the more common pediatric problems of the foot associated with microtrauma. In the author's experience, most pediatric foot problems in sports are related to the biomechanics of the foot and lower extremity and most of their treatment is directed toward improving the immediate problem at hand and ...

The general nature and function of the AFO has been presented. These devices encompass the foot and leg crossing the ankle joint. They may insert into the shoe or attach to the shoe. The more recent AFOs are made of polypropylene and were formerly composed of steel. The indications for ...

Although the development of an HIV vaccine may eventually provide a means of controlling AIDS in developed countries, more immediate and less sophisticated methods are going to have to be developed for use in the rural regions of Africa where AIDS may already have reached epidemic proportions. Evidence from several ...

When Tetrahymena thermophila was incubated with taurolipid A isolated from T. pyriformis NT-1, the exogenously added taurolipid A was deacylated rapidly, and taurolipid B content in the cells was increased. The deacylated taurolipid A (lysotaurolipid A) content reached a maximum early on during incubation, and then declined. Taurolipid B and ...

The author describes the maldistribution of psychiatric physicians in British Columbia, speculates on the causes of that phenomenon, and summarizes the response to the problem provided by the Psychiatric Outreach Program, a project sponsored jointly by the Ministry of Health and the University of British Columbia.

Skin problems are the cause of a high incidence of recurrent clubfoot problems. With respect to the demonstrated vascular territories (angiosomes) of the ankle and foot, the incisions which seem to be safest are vertical as opposed to transverse, and between angiosomes. The safest of all are the posteromedial incision ...

A procedure to assess functional abilities that can make compliance difficult for the older individual is described. The test can be constructed from items commonly found in the pharmacy. It has been designed to assist the pharmacist in identifying problems older individuals will have in taking their medications. The problems ...

In this study of fifty men and women with normal hand function, the strength of thumb to index finger pulp to pulp pinch grip was assessed with the remaining fingers either flexed or extended. When the pinch grip was performed with the remaining fingers flexed the value was up to ...

The foot is a highly cathected appendage that is commonly singled out as the brunt of humorous or derisive remarks, as if it embodies repugnance and disgust. Attitudes toward the foot are overdetermined, bearing the imprint of man's early linguistic patterns and individual dynamics. This article suggests that feet are ...

We treated a case of laryngeal trauma in which difficulty in high-pitched phonation was the main feature of a voice problem. We emphasize the importance of phonatory function tests in determining the mechanism of voice disorders and in monitoring the effects of treatment. Physical examination, phonatory function tests, computed tomographic ...

The molded polypropylene orthosis offers many advantages in the treatment of foot and ankle problems in cerebral palsy. Numerous balancing, stance phase, and swing phase difficulties are treated with an ankle-foot orthosis with appropriate molding to correct each specific problem. Various foot orthoses can also be used to control dynamic ...

Postural impositions on the foot and ankle in cerebral palsied patients may be due to neurological or biomechanical causes. Neurological etiology is related to retained neonatal automatisms, mass reflexes, lack of phasic muscle activity, and lack of voluntary control. Biomechanical impositions on the foot and ankle of superincumbent deformities in ...

A type of valgus deformity of the foot which differs from those commonly recognized is described. In this foot, correction of the hindfoot valgus results in the talus assuming an abnormally horizontal position, so that the forefoot is markedly rotated relative to the hindfoot. The condition is usually present at ...

An old problem of the evolution of finitely many interacting point vortices in the plane is shown to be amenable to investigation by critical point theory in a way that is identical to the study of the planar n-body problem of celestial mechanics. For any choice of positive circulations of ...

In this paper I suggest that much of recent experiment in analytic theory, even widely diverse approaches, has a common denominator the problem of the conceptual vacuum created by the shift away from a central creative position of the idea of psychic mechanisms. I try to illustrate, by comparing theories ...

Two of 33 prostatic tumour xenografts were established and passaged. Testosterone supplementation did not improve tumour take rates. The histological grade of the parent tumour was the principal factor affecting xenograft survival. Preliminary studies on established tumour xenografts suggest that their value lies in the study of tumour biology, and ...

Positional communication and the functional coupling of muscular reflexes were examined in grafted hydra. A head and distal gastric region inhibited head regeneration by a host sub-hypostome within 4--5 h of grafting. Functionally coupled pathways which indicated the presence of gap junctions also formed between graft and host during this ...

The problem of consciousness is discussed briefly, including the contrary views of consciousness as a transcendental phenomenon and as an animistic fiction. Measurement of consciousness is possible only indirectly by means of quantitative assessment of accompanying behavioral deficits. Knowledge of the structural basis of consciousness is incomplete. The ascending reticular ...

A simple discriminant function using midshaft femoral circumference for the determination of sex has been tested with 114 skeletons from the Libben Site, Ontario County, Ohio. The results have been shown to be 85% consistent with other, accepted means of determining sex. Femur circumference an be an aid to the ...

In general, painful feet can affect the performance of an athlete in any sport. To prevent skin diseases of the feet, the "Athlete's Foot" should be kept clean and dry with toenails trimmed. Properly fitting athletic shoes should be worn to avoid the formation of blisters. Wearing of sandals in ...

The problem of concern is the minimization of a convex function over a normed space (such as a Hilbert space) subject to the constraints that a number of other convex functions are not positive. As is well known, there is a dual maximization problem involving Lagrange multipliers. Some of the ...

The aims of knee replacement are to provide freedom from pain and a return to a resonable level of function. A survey was undertaken to determine the functional advantages of knee replacement and problems that may still be encountered by the patient. The results of the survey highlighted certain advantages ...

The problem of minimizing a convex function that is subject to the constraint that a number of other convex functions be nonpositive can be treated by the Lagrange multiplier method. Such a treatment was revived by Kuhn and Tucker and further studied by many other scientists. These studies led to ...

Previous work has lead the author to conjecture necessary and sufficient conditions for the subellipticity of the [unk]-Neumann problem on pseudoconvex domains. Here we outline a general method which reduces the problem of subellipticity to inequalities between germs of C(infinity) functions. We then describe how this method can be applied ...

In this paper we investigate a Darboux problem for a polyvibrating equation with analytic data. It is solved by the F-function approach of C. Truesdell, extending his F-equations to functions with several variables.

The application of Phillips' perturbation theorem to Cauchy's problem for higher-order parabolic equations is justified by an argument from the theory of Fourier transforms of entire functions.

A polydactylous right front foot was collected from a white -tailed deer (Odocoileus virginianus) fawn in eastern Ontario, Canada. We determined by gross visual and radiographic examinations that the polydactylous foot had a complete extra digit in the position of the ancestral 1st digit. This is the first documented account ...

Two problems of Fourier analysis on GL(n,R) are studied. The first concerns the decomposition of the additive Fourier operator in terms of the group representation theory of G. The second concerns the analytic continuation of certain zeta-functions defined on G. It is found that the generalized Gamma functions of Gelfand ...

Recent advances in technology are transforming our lives, but in many cases they are also limiting the way children are exposed to local communities and physical spaces. Technology can help young people actively connect with their neighborhoods, but doing that requires different methods and tools from the ones typically available ...

HIV will only be defeated when behavioural means of prevention become the basis of the global response.

In this study the diffusion and adoption framework is used to investigate a family planning innovation. The study indicates the utility of this framework from an analytical point of view both for the researcher to the process by which family planning comes to be adopted, and for the administrator to ...

Allium cernuum, Vicia faba, and Tradescantia paludosa were treated by root immersion in maleic hydrazide (1 mM/liter) labeled with C(14) (C(14)-MH) for 1 hour to determine the location within the cell to which MH moves during various periods of time after treatment. Root tips were fixed 24 hours, 48 hours, ...

The cytoplasm of the hepatic cell contains, besides the well known organelles, microbodies, characterized by a single membrane, a finely granular matrix, and average dimensions below those of mitochondria. Microbodies, rare in normal cells, become more numerous in regenerative livers and in various pathological conditions. In these cases, they either ...
