Quantum sensing of microRNAs with nitrogen-vacancy centers in diamond.

Label-free detection of nucleic acids such as microRNAs holds great potential for early diagnostics of various types of cancers. Measuring intrinsic biomolecular charge using methods based on field effect has been a promising way to accomplish label-free detection. However, the charges of biomolecules are screened by counter ions in solutions over a short distance (Debye length), thereby limiting the sensitivity of these methods.

ND0701, A Novel Formulation of Apomorphine for Subcutaneous Infusion, in Comparison to a Commercial Apomorphine Formulation: 28-Day Pharmacokinetic Study in Minipigs and a Phase I Study in Healthy Volunteers to Assess the Safety, Tolerability, Pharmacokinetics and Relative Bioavailability.

Background: Subcutaneous apomorphine is used for the treatment of Parkinson's disease (PD); however, infusion site reactions are a common adverse event (AE), which can lead to treatment discontinuation. Apomorphine formulations that are more tolerable and convenient for use are needed.

Objective: Our aim was to compare the toxicity and bioavailability of ND0701, a new concentrated formulation of apomorphine free base, with one of the commercially available apomorphine HCl formulations (APO-go, Britannia Pharmaceuticals Ltd).

Ninety-day Local Tolerability and Toxicity Study of ND0612, a Novel Formulation of Levodopa/Carbidopa, Administered by Subcutaneous Continuous Infusion in Minipigs.

A 90-day study in Göttingen minipigs was conducted to test the local tolerability and systemic toxicity of ND0612, a novel aqueous solution of carbidopa (CD)/levodopa (LD) intended for the treatment of Parkinson's disease by continuous subcutaneous administration using a discrete infusion pump. To evaluate tissue site reactions, we used a unique study design involving multiple infusion sites to evaluate the effect of dose per site (270/63, 360/45, and 360/84 mg LD/CD), volume of infusion per site (4.5 and 6 ml per site), formulation concentration (60/14 and 60/7.

An aquarium hobbyist poisoning: Identification of new palytoxins in Palythoa cf. toxica and complete detoxification of the aquarium water by activated carbon.

Palytoxin (PLTX) is a lethal natural toxin often found in Palythoa zoantharians that, together with its congeners, may induce adverse effects in humans after inhalation of toxic aerosols both in open-air and domestic environments, namely in the vicinity of public and private aquaria. In this study, we describe a poisoning of an aquarium hobbyist who was hospitalized after handling a PLTXs-containing zoantharian hexacoral. Furthermore, we provide evidence for water detoxification.

Combined antihypertensive and cardioprotective effects of nebivolol and hydrochlorothiazide in spontaneous hypertensive rats.

The antihypertensive and cardioprotective effects of the combination of nebivolol (NEB) and hydrochlorothiazide (HCTZ) in spontaneously hypertensive rats (SHR) were investigated. SHR and age-matched Wistar-Kyoto normotensive rats were randomly assigned to one of six groups: SHR treated with NEB (1 mg/kg/day, intragastric); SHR treated with HCTZ (5 mg/kg/day, intragastric); SHR treated with NEB plus HCTZ (1 + 2.5 mg/kg/day); SHR treated with NEB plus HCTZ (1 + 5 mg/kg/day), along with a SHR and a WKY control group.

Factors affecting injury severity among recreational skiers and snowboarders: an epidemiology study.

Different results have been reported for skiing and snowboarding injuries worldwide. Few studies consider the injury severity score (ISS) for the evaluation of differences among injured skiers-snowboarders. The aim of this study is to identify possible risk factors that affect the severity of skiing and snowboarding injuries in three winter seasons (2002-2005) in South Tyrol.

Is antibiotic prophylaxis necessary in elective laparoscopic surgery for benign gynecologic conditions?

Background: The use of prophylactic antibiotics in gynecologic laparoscopic surgery is still popular and many gynecologic surgeons believe that prophylactic antibiotic therapy will decrease the incidence of postoperative infection complications.

Aim: The aim of this prospective cohort study was to investigate the opportunity of prophylactic antibiotics to prevent early postoperative infections and febrile morbidity in elective laparoscopic surgery for benign gynecological conditions.

Methods: 300 women who underwent laparoscopic surgery for benign gynecological conditions were included in the study.

ACE inhibition and protection from doxorubicin-induced cardiotoxicity in the rat.

The angiotensin converting enzyme inhibitor zofenopril has been shown to possess cardioprotective effects toward myocardial damage induced by chronic doxorubicin treatment in the rat. In the present study we have investigated the relationship between cardioprotection exerted by 2 angiotensin converting enzyme inhibitors (zofenopril and lisinopril) and degree of inhibition of cardiac versus serum angiotensin converting enzyme. Both zofenopril and lisinopril produced a dose-dependent inhibition of serum and cardiac angiotensin converting enzyme in rats (0.

Skiing and snowboarding injuries and their impact on the emergency care system in South Tyrol: a restrospective analysis for the winter season 2001--2002.

Objectives: To evaluate the incidence and the pattern of skiing and snowboarding injuries in South Tyrol and their impact on the emergency medical system in the winter season 2001--2002 in an attempt to rationalize and improve the emergency care and assist in prevention strategies.

Methods: All medical records of patients referred to our emergency department (ED) that sustained a skiing or snow-boarding injury during the study period were retrospectively reviewed. Age, sex, local or non-local residency, type of injury, data and time of accident, type of transport to the hospital, hospital admission or ED discharge, Injury Severity Score, outcome (including mortality) were evaluated.

Study Design: From January 1996 to December 2000, 36 women referred to our endoscopy center underwent hysteroscopic metroplasty. Follow-up covered the incidence of pregnancy, term pregnancies and mode of delivery.

Carbon dioxide versus normal saline in outpatient hysteroscopy.

Background: The aim of this prospective randomized study was to measure patients' discomfort after hysteroscopy with CO(2) or normal saline.

Methods: A total of 415 patients was randomized to two groups according to distension medium (CO(2), n = 201; normal saline, n = 214). The nature of randomization was to alternate distension media on a weekly basis.

Chronic cardiotoxicity of anticancer anthracyclines in the rat: role of secondary metabolites and reduced toxicity by a novel anthracycline with impaired metabolite formation and reactivity.

(1) The anticancer anthracycline doxorubicin (DOX) causes cardiomyopathy upon chronic administration. There is controversy about whether DOX acts directly or after conversion to its secondary alcohol metabolite DOXol. Here, the role of secondary alcohol metabolites was evaluated by treating rats with cumulative doses of DOX or analogues--like epirubicin (EPI) and the novel disaccharide anthracycline MEN 10755--which were previously shown to form less alcohol metabolites than DOX when assessed in vitro.
