As sentinel node biopsy has emerged as a possible alternative to axillary node dissection in patients with operable breast cancer, this procedure is also emerging as a possible alternative in patients who have received prior neoadjuvant chemotherapy.…
Animal models that are biologically and clinically relevant are essential for conducting research to investigate the pathophysiologic progression of disease and to develop diagnostic or therapeutic strategies. Several rodent models that vary in…
Mitochondrial sterol 27-hydroxylase (CYP27A1) catalyses sterol side-chain oxidation of bile acid synthesis from cholesterol, and the first reaction of the acidic bile acid biosynthetic pathway. Hydrophobic bile acids suppress human CYP27A1 gene…
Mitochondrial sterol 27-hydroxylase (CYP27Al) catalyses sterol side-chain oxidation of bile acid synthesis front cholesterol, and the first reaction of the acidic bile acid biosynthetic pathway. Hydrophobic bile acids suppress human CYP27Al gene…
Nasal defects in certain areas such as the columellar-lobular junction, the alar rim and the soft triangle are cosmetically challenging to reconstruct. This paper describes a technique that enables the use of composite grafts for these specific nasal…
To probe the molecular nature of the binding pocket of a G protein-coupled receptor and the events immediately following the binding and activation, we have modified the substance P peptide, a potent agonist for the neurokinin-1 receptor, with a…
We previously found that prolonged isoproterenol (Iso) infusion in rats impaired the ability of beta-adrenoceptor (beta-AR) agonists to increase alveolar liquid clearance (ALC). Here, we determined if postreceptor defects in beta-AR signaling…
To understand further the effects of spaceflight on osteoblast-enriched cultures, normal chicken calvarial osteoblasts were flown aboard shuttle flight STS-77, and the total number of attached cells was determined. Spaceflight and control cultures…
The organization of collagen fibrils differs in woven bone and lamellar bone, and it reflects certain aspects of the nature of the mineral crystals associated with them. In order to investigate the morphology and distribution of apatite crystals in…
Recent discoveries in opioid pharmacology help explain the enormous variability in clinical responses to these powerful analgesics. Although there is only one m opioid receptor gene, splice variants of that gene's expression result in a panoply of…
Background: Eradication of Helicobacter pylori infection has had an impact on the treatment and recurrence rates of peptic ulcer disease and malignancies such as mucosa-associated lymphoid tissue lymphoma. Treatment options are cumbersome, expensive,…
A 67-year-old woman had fever, myalgias, progressive weakness, and respiratory insufficiency. In 9 days, flaccid areflexic quadriparesis and bulbar palsy developed. She died 26 days after the onset of her illness. Serum and cerebrospinal fluid…
The idea of using preoperative or neoadjuvant chemotherapy in patients with operable breast cancer originated from experimental and clinical observations as well as theoretical hypotheses on tumor cell growth and dissemination. Initially,…
Necrotizing soft tissue infections are characterized by necrosis of skin and associated structures. Despite advances in the diagnosis and treatment of these infections, the mortality remains high. There have been increasing reports of necrotizing…
UV-inactivated, infectious, and other forms of herpes simplex virus 1 (HSV-1) induced interferon (IFN) production by different routes in myeloid origin mononuclear cells (MOMC) (consisting predominantly of monocytes). GM-CSF activated the MOMC…
The Acute Care for Elders (ACE) model of care is a multicomponent intervention that improves outcomes for older patients hospitalized for acute medical illnesses. Likewise, stroke units improve outcomes for patients with acute stroke, yet the…
BACKGROUND: Medical Students for Choice is a U.S.-based organization concerned with the shortage of abortion providers, the lack of abortion education in medical schools, and violence against abortion providers. Created in 1993, MSFC has 110 chapters…
Background/aims: The influence of mechanical forces on skin has been examined since 1861 when Langer first reported the existence of lines of tension in cadaver skin. Internal tension in the dermis is not only passively transferred to the epidermis…
Objective. To use noninvasive magnetic resonance imaging (MRI), biochemical analyses, and mechanical testing of engineered neocartilage grown in a hollow-fiber bioreactor (HFBR) to establish tissue properties, and to test the hypothesis that MRI can…
Spinal accessory nerve injury results in a debilitating shoulder dysfunction. The trapezius is a major suspensory muscle of the shoulder girdle, and paralysis results in chronic pain and debility from disruption of synchronous scapulohumeral rhythm.…
Patients with community-acquired pneumonia (CAP) are treated in hospital or in the ambulatory care setting depending on the severity of illness. Despite numerous guidelines proposed, there is no agreement on specific criteria for hospitalization…
In the interest of publicizing examples of funded qualitative health research, the authors share a proposal to the Ageney for Healthcare Research and Quality in Washington, D.C., in which they sought to elicit patient stories of preventable problems…
