Tropospheric ozone is one of six criteria pollutants regulated by the US EPA, and has been linked to respiratory and cardiovascular endpoints and adverse effects on vegetation and ecosystems. Regional photochemical models have been developed to study the impacts of emission reductions on ozone levels. The standard approach is to run the deterministic model under new emission levels and attribut...

Amplitude-weighted mean velocity from continuous wave (CW) Doppler spectra was used to measure aortic flow (QAo) and left ventricular mitral inflow (QLVin). These flows were used to quantify mitral regurgitation fraction: RFm = (QLVin-QAo).QLVin-1.100(%).QLVin was calculated from the diastolic time integral of amplitude-weighted mean velocity that was derived from CW spectra with the transducer...

A class of rifampin-resistant (rfm) mutations of Bacillus subtilis suppresses the temperature-sensitive sporulation of a fusidic acid-resistant mutant. FUS426, which has an altered elongation factor G. The rfm mutation suppressed only the sporulation defect caused by the elongation factor G mutation, but could not suppress other types of induced sporulation defects. Genetic and biochemical anal...

Poly(ADP-ribose) glycohydrolase (PARG) is the enzyme which degrades poly(ADP-ribose) polymers synthesized by poly(ADP-ribose) polymerase (PARP). Both enzymes are activated in response to different stimuli like oxidative stress and are involved in DNA repair processes. The retention of bovine foetal membranes (RFM) is supposed to be connected with oxidative stress conditions. The aim of the stud...

The objective of this study was to determine the effect of a calcium-energy supplement at calving on the incidence of calving-related disorders (CRD), fertility, BCS and milk yield in cows fed anionic diets and to establish any associations among outcome variables. In Florida, from October to December 1997, 479 cows were assigned to three groups and treated at calving as follows: Group 1: 160 n...

Over-parameterization and over-correction are two of the major problems in the rational function model (RFM). A new approach of optimized RFM (ORFM) is proposed in this paper. By synthesizing stepwise selection, orthogonal distance regression, and residual systematic error correction model, the proposed ORFM can solve the ill-posed problem and over-correction problem caused by constant term. Th...

Research Associate, College of Vety.Sc.& A.H., Anjora, Durg, Chhattisgarh (India) The present study was performed in 12 buffaloes, six with retained fetal membrane and six normal parturient buffaloes. Blood samples were taken for estimation of some haematological and biochemical constituents. The total leucocyte count, and eosinophil, monocyte and basophil percent did not vary significantly bet...

We reveal that males of two members of the Anopheles gambiae s.l. species complex, Anopheles coluzzii and Anopheles gambiae s.s. (hereafter A. gambiae), which are both malaria vectors, perform a stereotypical acoustic behaviour in response to pure tones at frequencies that encompass the frequency range of the female's flight-tones. This behaviour resembles that described for Culex quinquefascia...

OBJECTIVES To access the effectiveness of radiofrequency myolysis (RFM) in women with midline dysmenorrhea. METHODS We designed RFM in two ways laparoscopic RFM (LRFM), vaginal ultrasound-guided RFM (URFM). One hundred and thirty-two patients were in the LRFM group and, 140 patients were in the URFM group. RESULTS Upon receipt of surgery, both the LRFM and the URFM groups demonstrated a sig...
