Investigation of chemosensitivity during and after an acute cold.

Background: Viral rhinitis (the "common" cold) is a frequent worldwide disease. Olfactory dysfunction is one complication that arises during infection, which in most cases heals up spontaneously upon recovery, whereas in some cases it may persist as a partial or total loss of olfaction. The aim of this prospective study was to investigate the change of other chemosensory systems during a cold.

Toward Quantitative Whole Organ Thermoacoustics With a Clinical Array Plus One Very Low-Frequency Channel Applied to Prostate Cancer Imaging.

Thermoacoustics has the potential to provide quantitative images of intrinsic tissue properties, most notably electrical conductivity in Siemens/meter, much as shear wave elastography provides tissue stiffness in kilopascal. Although thermoacoustic imaging with optical excitation has been commercialized for small animals, it has not yet made the transition to clinic for whole organ imaging in humans. The purpose of this work was to develop and validate specifications for a clinical ultrasound array for quantitative whole organ thermoacoustic imaging.

Does polyomavirus infection interfere with bladder cancer fluorescence in situ hybridization?

Urine cytology is a proven and widely used screening tool for the detection of urothelial carcinoma. However, morphologic features of polyomavirus infected cells, characterized by nuclear inclusions (decoy cells) are a known source of diagnostic confusion with malignancy. Fluorescence in situ hybridization (FISH) is now routinely used to support the cytological diagnosis of urothelial carcinoma and monitor for recurrence.

Doxylamine pharmacokinetics following single dose oral administration in children ages 2-17 years.

To characterize doxylamine pharmacokinetics in children. This study was conducted in 41 subjects, ages 2-17 years. Doxylamine succinate doses based on age/weight ranged from 3.

Acute myeloid leukemia following solid organ transplantation: case report and comprehensive review.

Organ transplant recipients are at an increased risk for subsequent malignancies including hematologic malignancies. The development of acute myeloid leukemia (AML) after solid organ transplantation is a rare but well-documented event. It is thought to be a consequence of immune dysregulation secondary to the use of immunosuppressive agents.

Defining Darwinism.

Evolutionary theory seems to lend itself to all sorts of misunderstanding. In this paper I strive to decrease such confusions, for example, between Darwinism and Darwinians, propositions and people, organisms and individuals, species as individuals versus species as classes, homologies and homoplasies, and finally essences versus histories.

Periodontitis and inflammatory markers in transplant recipients.

Background: Inflammation is associated with the deterioration of solid-organ transplants. Chronic periodontitis is linked to systemic inflammation, although it is unknown whether it plays a causative or comorbid role. We hypothesized that transplant subjects have a greater prevalence of severe periodontitis, accompanied by higher levels of serum interleukin-6 (IL-6) and C-reactive protein (CRP), compared to systemically healthy subjects.

Precursor of prostate-specific antigen expression in prostatic intraepithelial neoplasia and adenocarcinoma: a study of 90 cases.

Objective: To assess the expression of the precursor of prostate-specific antigen (pro-PSA), a distinct molecular form of serum-free PSA that includes native and truncated forms, in benign epithelium, high-grade prostatic intraepithelial neoplasia (PIN) and prostatic adenocarcinoma.

Materials And Methods: We immunohistochemically evaluated 90 formalin-fixed, paraffin-embedded prostate needle biopsies using monoclonal antibodies against [-2] pro-PSA, native [-5/-7] pro-PSA, prostate-specific membrane antigen (PSMA), PSA and racemase. Staining intensity was recorded using a scale of 0-3 (0, no staining; 3, highest staining).

Transplantation of a unilateral fused kidney with inferior ectopia: revascularization utilizing donor aorta and vena cava.

We present a case of kidney transplantation utilizing a fused kidney with inferior ectopia. The kidney had three arteries, five veins and two ureters and was procured en bloc with the donor vena cava and aorta. The caudal end of the donor vena cava was anastomosed to the recipient's external iliac vein.

Donor postextubation hypotension and age correlate with outcome after donation after cardiac death transplantation.

Background: Compared with standard donors, kidneys recovered from donors after cardiac death (DCD) exhibit higher rates of delayed graft function (DGF), and DCD livers demonstrate higher rates of biliary ischemia, graft loss, and worse patient survival. Current practice limits the use of these organs based on time from donor extubation to asystole, but data to support this is incomplete. We hypothesized that donor postextubation parameters, including duration and severity of hemodynamic instability or hypoxia might be a better predictor of subsequent graft function.

Androgen deprivation therapy for precancerous lesions of the prostate.

Androgen deprivation therapy has become well-established in the treatment of prostate cancer. Luteinizing-hormone-releasing hormone (LHRH) agonists, anti-androgens, orchiectomy, and combination hormonal therapy are treatment options offered to select patients. The prospect of intervention prior to the development of adenocarcinoma is appealing, and high-grade prostate intra-epithelial neoplasia (PIN), the only known precursor, is the best possible target.

Adult urinary bladder rhabdomyosarcoma.

Rhabdomyosarcomas, malignant neoplasms exhibiting skeletal muscle differentiation, are the most common childhood sarcomas and most commonly arise in the head-and-neck region. Embryonal rhabdomyosarcomas of the genitourinary tract also occur in children, but are distinctly uncommon in adults. We report a case of embryonal rhabdomyosarcoma arising in the bladder of a 39-year-old woman who presented with urgency, frequency, and gross hematuria.

Assessment of antitussive efficacy of dextromethorphan in smoking related cough: objective vs. subjective measures.

What Is Already Known About This Subject: Dextromethorphan is widely used as a cough suppressant in over the counter medications. Its efficacy in altering cough reflex sensitivity has been shown in healthy volunteers. In contrast evidence for an effect on clinically important cough is poor.

Low pH gel intranasal sprays inactivate influenza viruses in vitro and protect ferrets against influenza infection.

Background: Developing strategies for controlling the severity of pandemic influenza is a global public health priority. In the event of a pandemic there may be a place for inexpensive, readily available, effective adjunctive therapies to support containment strategies such as prescription antivirals, vaccines, quarantine and restrictions on travel. Inactivation of virus in the intranasal environment is one possible approach.

A severely affected female infant with x-linked dominant chondrodysplasia punctata: a case report and a brief review of the literature.

We recently performed an autopsy on a premature female newborn with rhizomesoacromelic limb shortening of the upper and lower extremities, craniofacial dysmorphism, and chondrodysplasia punctata. A diagnosis of Conradi-Hunermann-Happle syndrome or X-linked dominant chondrodysplasia punctata was made based on elevated cholest-8(9)-ene-3beta-ol in serum and tissues. Molecular analysis of EBP, mutations of which are responsible for this malformation syndrome, revealed a monoallelic missense mutation, c.

Carbon nanostructure examined by lattice fringe analysis of high-resolution transmission electron microscopy images.

The dimensions of graphitic layer planes directly affect the reactivity of soot towards oxidation and growth. Quantification of graphitic structure could be used to develop and test correlations between the soot nanostructure and its reactivity. Based upon transmission electron microscopy images, this paper provides a demonstration of the robustness of a fringe image analysis code for determining the level of graphitic structure within nanoscale carbon, i.

Investigations in subjects with cough following upper respiratory tract infection.

The study aimed to investigate subjects with cough following acute upper respiratory tract infection (URTI), and to compare those subjects unable to suppress cough ("non-suppressors") with those who were able to suppress cough ("suppressors"). Forty-three URTI subjects participated, 31 with cough associated with acute URTI and 12 healthy controls; 21 of the coughing subjects were "suppressors", 10 were "non-suppressors". We obtained responses to chemical and mechanical stimulation of the nasal cavity or the pharynx using both psychophysical measures and event-related potentials.

Deconstructing Darwin: Evolutionary theory in context.

The topic of this paper is external versus internal explanations, first, of the genesis of evolutionary theory and, second, its reception. Victorian England was highly competitive and individualistic. So was the view of society promulgated by Malthus and the theory of evolution set out by Charles Darwin and A.

The antitussive effect of placebo treatment on cough associated with acute upper respiratory infection.

Objective: The objective of this study was to determine the effects of a placebo treatment on cough in patients with cough associated with acute upper respiratory tract infection (URTI).

Methods: Patients with dry or slightly productive cough associated with a history of URTI were recruited. Cough frequency (CF) over 15 minutes was recorded by means of a microphone connected to a pen recorder.

Primary carcinoid tumor of the common hepatic duct: A rare case with immunohistochemical and molecular findings.

We report immunohistochemical (IHC) and molecular findings in a rare case of a carcinoid tumor of the extrahepatic bile ducts in a 33-year-old woman, who presented with a 3.9x2.8x2.

Recent philosophy of biology: a review.

Academia is subdivided into separate disciplines, most of which are quite discrete. In this review I trace the interactions between two of these disciplines: biology and philosophy of biology. I concentrate on those topics that have the most extensive biological content: function, species, systematics, selection, reduction and development.

Assessment of pharyngeal sensitivity to mechanical stimuli using psychophysical and electrophysiological techniques.

The investigation was aimed to assess pharyngeal sensitivity by means of intensity ratings and event-related potentials (ERPs) to mechanical stimulation. Twenty healthy subjects participated (14 female, mean age 23.6 years).
