It was proposed that the power stroke in primates has two distinct periods of occlusal contact, each with a characteristic motion of the mandibular molars relative to the maxillary molars. The two movements are called phase I and phase IT, and they…
Objectives. To prospectively evaluate quality of life (QoL), use of complementary and alternative medicine (CAM), and diet/exercise changes in ovarian cancer patients during the first 6 months following diagnosis. Methods. Patients with newly…
Recent morphometric analyses have led to dissimilar conclusions about whether the jaws of tree-gouging primates are designed to resist the purportedly large forces generated during this biting behavior. We further address this question by comparing…
Background and context: There is a basis for the assumption that feedback can be used to enhance physicians' performance. Nevertheless, the findings of empirical studies of the impact of feedback on clinical performance have been equivocal.…
The multiple disease etiologies that lead to neuropsychiatric disorders, such as Parkinson's and Alzheimer's disease, amyotrophic lateral sclerosis, Huntington disease, schizophrenia, depressive illness and stroke, offer significant challenges to…
Background: Cancer risk assessment begins in the primary care clinician's office. Essential components of that process include: 1) documentation of personal and family cancer information; 2) identification of families at increased risk for cancer; 3)…
Objectives: In recognition of the fact that police are often the first responders for individuals who are experiencing a mental illness crisis, police departments nationally are incorporating specialized training for officers in collaboration with…
Objectives. To assess the utility of positional instillation of contrast (PIC) cystography in detecting vesicoureteral reflux (VUR) in patients with renal scarring from recurrent febrile urinary tract infections that standard voiding…
Purpose: To present a novel in-vitro pig model for testing the design and function of different internal catheter constructs, along with the resulting exit wound resulting from removal. Materials and Methods: We compared the pullout parameters of two…
The current study examines regulation of CYP7B1, a DHEA 7 alpha-hydroxylase, by sex hormones. Transfection with estrogen receptor alpha and treatment with 17 P-estradiol in human embryonic kidney 293 cells significantly increased CYP7B1 catalytic…
Purpose Lymph node (LN)-negative breast cancer tumors >= 5 cm occur infrequently, and their optimal management is not well defined. In this study, we assess patterns of locoregional failure (LRF) in LN-negative patients who underwent mastectomy,…
A recent lack of availability of the anesthetic agent methohexital in the United States allowed for a naturalistic study of the efficacy and the adverse effects of alternatives. Methohexital, propofol, and thiopental were compared as anesthetic…
Some investigators have reported that endogenous beta-adrenoceptor tone can provide protection against acute lung injury. Therefore, we tested the effects of beta-adrenoceptor inhibition in mice with acute Escherichia coli pneumonia. Mice were…
Background: Foot burns in children often result from contact with heated surfaces due to high ambient temperatures during summer in the southwestern United States. The objective of this study was to describe the unique cause and clinical…
A complex plasma disc (CPD) is a stable two-dimensional arrangement of it particles, each with mass in and charge q, confined by a parabolic well and interacting through a shielded Coulomb force (i.e. a Yukawa potential). It is shown that the…
The transcription of the cholesterol 7 alpha-hydroxylase gene (CYP7A1) is greatly decreased in cholesterol-fed rabbits. To determine whether the molecular structure of the promoter is responsible for this downregulation, we cloned the rabbit CYP7A1…
Objectives: The aim of this study was to correlate the anatomic and clinical significance of the prepubic course of dorsal nerve of penis and its groove on the pubic bone from the perspective of the surgeon. Methods: The course of the dorsal nerve of…
As part of a broader effort to identify postreceptor signal regulators involved in specific diseases or organ adaptation, we used an expression cloning system in Saccharomyces cerevisiae to screen cDNA libraries from rat ischemic myocardium, human…
Background/Aims: Hemodialysis patients are often hospitalized, during which time they require continuity of care in the inpatient setting. The goal of the present study was to evaluate the clinical outcomes associated with a conversion algorithm from…
Objectives. Because several experimental studies have demonstrated that cyclic adenosine monophosphate generation following beta-adrenoceptor activation can markedly stimulate alveolar fluid clearance, we determined whether the endogenous levels of…
The purpose of this study was to assess birds as a potential model for osteoarthritis. Compromised by confounding factors, it has not been possible to clearly delineate causation in humans. Nonhuman mammals manifest osteoarthritis in the natural…
The hypothesis of disease-related large mammal extinction has new support. A unique pathologic zone of resorption was first noticed in a Hiscock Mammut americanum metacarpal. The pathognomonic zone of resorption was present in fifty-nine (52%) of 113…
Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population…
There is significant diversity in growth plate behavior among sites within an individual skeleton and between skeletons of different species. This variation within wild-type animals is an underutilized resource for studying skeletal development. One…
The construct of "other-directed versus self-directed career choice" has existed for quite some time. The current focus of vocational psychologists and counselors has made them question the relevance of this construct for contemporary American…
One of the intents of tissue engineering is to fabricate biological materials for the augmentation or replacement of impaired, damaged, or diseased human tissue. In this context, novel models of the human phalanges have been developed recently…
Objective. The purpose of this series was to describe the fetal echocardiographic findings in hypoplastic left heart syndrome with aortic atresia and ventriculocoronary arterial communication and implications of these findings. Methods. We describe 2…
Objective. The purpose of this series is to describe the prenatal echocardiographic findings of vascular rings. Methods. The 3-vessel and trachea view consists of the axial view of the upper mediastinum. The normal left aortic arch appears as a…
We have generated immortal neuronal cell lines from normal and trisomy 16 (Ts16) mice, a model for Down syndrome (DS). Ts16 lines overexpress DS-related genes (App, amyloid precursor protein; Sod1, Cu/Zn superoxide dismutase) and show altered…
The marsupial middle ear performs an anatomical impedance matching for acoustic energy travelling in air to reach the cochlea. The size of the middle ear sets constraints for the frequencies transmitted. For generalized placental mammals, it has been…
The skulls and isolated tympanics are described for the earliest whales, pakicetids, from the H-GSP Locality 62 in the Ganda Kas area in Northern Pakistan. Currently three pakicetid genera are known: Pakicetus, Ichthyolestes, and Nalacetus.…
The Sequential Intercept Model provides a conceptual framework for communities to use when considering the interface between the criminal justice and mental health systems as they address concerns about criminalization of people with mental illness.…
