We are taught that gauge transformations in classical and quantum mechanics do not change the physics of the problem. Nevertheless, here we discuss three broad scenarios where under gauge transformations: (i) conservation laws are not preserved in the usual manner; (ii) non-gauge-invariant quantities can be associated ... |

The test bolus was 20 ml of local anaesthetic solution. The concentration was determined by the respon... |
We examined the validity and reproducibility of simulator-based driving evaluations. In Study 1, we examined correlations among Trails A and B, demerit points for simulated drives, and simulator-recorded errors. With one exception, correlations ranged from .44 (p = .103) to .83 (p = .001). In Study 2, we examined corre... |
Although the proteinase inhibitor alpha-2-antiplasmin (alpha 2AP) is known to control the activity of plasmin through rapid formation of stable complexes, it also efficiently inactivates chymotrypsin. These interactions are shown to occur at adjacent, overlapping sites so that plasmin attacks the inhibitor at an Arg364... |
Cyclosporin A is a potent immunosuppressive agent which inhibits activation of T cells and other inflammatory ceils. It has been shown to be of clinical benefit in patients with corticosteroid dependent asthma, but there are no data on its in vivo effects on airways inflammation. In this report, we describe the case of... |
OBJECTIVES |
To determine whether emergency medical technicians (EMTs) and paramedics suffer excessive hearing loss as a result of occupational noise exposure. A secondary objective was to determine noise levels in a modern ambulance. |
METHODS |
This retrospective study reviewed audiograms for EMTs and paramedics currently employed by the Louisville Emergency Medical Services. The age-adjusted threshold shift was calculated for the right and left ears at 1,000, 2,000, and 4,000 Hz in 81 of these individuals. Seventy-four of the subjects also had measurements t... |
RESULTS |
The correlation coefficient of age-adjusted threshold shifts and elapsed time was greatest at 2,000 Hz in the left ear but was still not significant at -0.2692. The noise levels in the ambulance ranged from 58 dBA in the patient compartment while stationary to 84 dBA in the forward cab with the windows down and the sir... |
CONCLUSION |
There was no significant correlation between the number of months elapsed between audiograms and the age-adjusted threshold shift at any frequency in either ear. There appears to be no excessive loss of hearing acuity in ambulance personnel. The noise levels in the study ambulance stayed well below the Occupational Saf... |
Recently, under the impacts of environmental shifts and human activities, marine ecosystem conservation and recovery have become increasingly important for the management and sustainable development of fishery resources.

A celebration is in order: the journal Radiocarbon is now a mature 50 years without drastic changes in its identity. There have been, of course, additions in terms of specific isotopes (it is now an international journal of cosmogenic isotope research), but the 14C content is still very extensive. The triannual offshoo... |

February 2019.Abstract 17103: Elevated NT-proBNP Level is Not a Prognostic Marker for Patients Hospitalized With SARS-CoV-2 Infection |
Introduction: |
NT-proBNP is a widely available and frequently utilized laboratory marker in patients with congestive heart failure. Its availability and use as a surrogate marker for elevated ventricular filling pressures and ventricular strain that frequently manifests as shortness of breath makes it an attractive laboratory marker... |
Hypothesis: |
Elevated NT-proBNP is correlated with higher mortality and/or rate of major adverse cardiovascular events (MACE) in patients admitted with SARS-CoV-2 infection. |
Methods: |
A retrospective analysis was performed on 225 patients admitted for SARS-CoV-2 infection at a major metropolitan hospital located in the Southwestern United States from the period of March 2020 to May 2020. NT-proBNP levels were recorded in 117 patients (52.7%) on admission. Elevated NT-proBNP was defined as: above 45... |
Results: |
Of the 117 SARS-CoV-2 positive patients that had admission NT-proBNP levels available for analysis, 23 (19.66%) met age-adjusted criteria for elevated NT-proBNP. There was no significant correlation between elevated NT-proBNP levels and MACE (p = 0.482) or mortality (p = 0.737) in patients with SARS-CoV-2 infections. ... |
Conclusions: |
An elevated NT-proBNP at time of admission does not significantly correlate with higher rates of MACE, hospital length of stay, ICU admission, and mortality in patients admitted with SARS-CoV-2 infection. |
Zero-quantum frequency-selective recoupling of homonuclear dipole-dipole interactions in solid state nuclear magnetic resonance. |
We describe a method for measuring magnetic dipole-dipole interactions, and hence distances, between pairs of like nuclear spins in a many-spin system under magic-angle spinning (MAS). This method employs a homonuclear dipolar recoupling sequence that creates an average dipole-dipole coupling Hamiltonian under MAS with... |
Several epidemiological and experimental studies have indicated a strong relationship between different types of dietary fats and risk of colon cancer. However, the modulating effects of these nutritional factors at the molecular level are not fully elucidated. It has been documented that the modulation of tumorigenesi... |
