Gorilla gorilla and the less-studied G. beringei occupy very different, geographically separate habitats. We studied the occurrence of various forms of arthritis to examine possible nature/nurture causality. The macerated skeletons of 38 G. beringei…

The character of arthritis has not received the same attention in Pan paniscus as it has in P. troglodytes. Reactive arthritis (a form of spondyloarthropathy) in the latter has been considered to be either a sexually transmitted or an…

We examined masseter and temporalis recruitment and firing patterns during chewing in five male Belanger's treeshrews (Tupaia belangeri), using electromyography (EMG). During chewing, the working-side masseters tend to show almost three times more…

ATP, an intracellular energy source, is released from cells during tissue stress, damage, or inflammation. The P2X subtype of the ATP receptor is expressed in rat dorsal root ganglion (DRG) cells, spinal cord dorsal horn, and axons in peripheral…

Heterotrimeric G-proteins are key transducers for signal transfer from outside the cell, mediating signals emanating from cell-surface G-protein coupled receptors (GPCR). Many, if not all, subtypes of heterotrimeric G-proteins are also regulated by…

What lies beneath the formal or overt curriculum may impair students' professional growth and development, including their ability to foster genuine relationships with patients and others, and may contribute to the inadvertent, often negative…

The founding of the William Carlos Williams poetry competition for medical students is recounted. A few highlights from its nearly twenty-five years of operation are offered. Gleanings from the hearts and souls of some of the winning poets are…

Spondyloarthropathy is a common occurrence in Old World primates, with only limited presence in New World monkeys. Clearly distinguished from rheumatoid arthritis, this erosive arthritis afflicts 20% of great apes, baboons, and rhesus macaques and…

Studies of gene expression from bone, cartilage, and other tissues are complicated by the fact that their RNA, collected and pooled for analysis, often represents a wide variety of composite cells distinct in individual phenotype, age, and state of…

This trial was conducted at 11 EDs to test the effectiveness of distributing fall prevention information to patients 65 years or older. Intervention patients were given 2 brochures and received a reminder call 2 weeks later. All patients were called…

During a 3-month period, a 33-year-old man presented to the emergency department on 4 occasions with dyspnea, palpitations, and syncope. His initial presentation was accompanied by acute myocardial injury and ventricular fibrillation. An extensive…

It has been reported that male mice are more susceptible to the neurotoxic effects of methamphetamine (MA) upon the nigrostriatal dopaminergic (NSDA) system. Since MA utilizes the dopamine transporter (DAT) to exert its effects, in the present study,…

A computer model based on relational database techniques was used to analyze the relationship between staging and population compliance to a breast cancer screening protocol. Stage distribution data permitted estimates of compliance to the protocol.…

Upper lid blepharoplasty is the most commonly performed operation in patients seeking facial rejuvenation. When evaluating the patient, attention should be focused on the possibility of concomitant eyelid or eyebrow ptosis. Meticulous planning and…

Community-acquired respiratory tract infections (CARTIs), including community-acquired pneumonia, acute exacerbations of chronic bronchitis, and acute bacterial sinusitis, contribute substantially to health care costs in the United States. Although…

We examined how maxillary molar dimensions change with body and skull size estimates among 54 species of living and subfossil strepsirrhine primates. Strepsirrhine maxillary molar areas tend to scale with negative allometry, or possibly isometry,…

BACKGROUND: Venous leg ulcers are a major cause of morbidity, economic loss, and decreased quality of life in affected patients. Recently, biomaterials derived from natural tissue sources have been used to stimulate wound closure. One such…

This article presents models of human phalanges and small joints developed by tissue engineering. Biodegradable polymer scaffolds support growth of osteoblasts, chondrocytes, and tenocytes after implantation of the models in athymic mice. The…

"Sinus headache" is a common complaint in the otolaryngology office. Recent literature has shown that the majority of patients with this complaint satisfy the diagnostic criteria for migraine. This review article presents an overview of the sinus…

It has been demonstrated that the gonadal steroid hormone estrogen can exert neuroprotective effects upon the nigrostriatal dopaminergic (NSDA) system against methamphetamine (MA)-induced neurotoxicity in female, but not male, mice. In contrast, the…

The nigrostriatal dopamine system shows marked gender differences that, in many cases, can be attributable to estrogen. However, the virtual absence of conventional estrogen receptors within the nigrostriatal dopamine system has made it difficult to…

Patients requesting skin correction and rejuvenation are motivated by a number of clinical problems. Photo damage, abnormal pigmentation or vascularity, textural problems, rhytides, and laxity due to chronological aging are the primary complaints of…

Techniques for facial rejuvenation have long involved specific remedies for each facial segment affected by the aging process. Traditional facial rejuvenation techniques have addressed the anterior neck and platysma complex as well as the acquired…

Techniques and concepts for treatment of the aging neck have been evolving since the late 1960s and rely on two-dimensional anterior approximation with lateral imbrication of the platysma with or without submental fat reduction, However, the medial…

Systematic survey of mammalian skeletons has revealed patterns of disease reproducible over geologic time. Systematic examination of non-passerine bird skeletons also reveals patterns of disease and identifies those disorders amenable to…

Evidence-based research now allows clear separation of syphilis from other diseases in its class of treponematoses. Examination of skeletons from populations with clinically diagnosed bejel and yaws revealed bone alterations distinctive to those…

BACKGROUND AND PURPOSE: Laparoscopic trainers have been shown to be effective tools for transitioning residents in surgical fields into live laparoscopic techniques. There have been few reports of homemade trainers, but each of these reports provides…

STUDY DESIGN: A human growth hormone transgene was bred into mice of the Cola2oim (oim) lineage. Caudal (tail) vertebrae from male and female mice at early skeletal maturity and at midlife were evaluated for physical and biomechanical properties.…

PURPOSE: We investigate the accuracy of urine volumes obtained by an automated bladder scan in complex neonatal cases. MATERIALS AND METHODS: Automated bladder scan determinations of urine volumes were obtained by neonatal intensive care unit nursing…

This is a case of a 3-week-old male who presented to the emergency department with intermittent apnea and cyanosis. While in the emergency department, he had respiratory compromise with stress and required intubation. Further evaluation confirmed the…
