The 52.8-hour activity of Pm149 has been investigated using a high resolution beta spectrometer, a lens type coincidence spectrometer, and a scintillation spectrometer in conjunction with a multichannel analyzer. The beta spectrum was found to consist of two groups with maximum energies of 1.072 ± 0.002 Mev and 0.786 ± 0.004 Mev, and intensities of 97.1 ± 0.4% and 2.9 ± 0.4% respectively. A gamma ray of energy 285.7 ± 0.3 kev was found to be in coincidence with the 0.786-Mev beta group. No other gamma rays with intensities greater than 0.1% were found. The K conversion coefficient for the 286-kev transition was measured to be 0.075 ± 0.008. This together with the values of 6.5 ± 0.7 and 4 ± 1 obtained for the K/L and L/M conversion ratios respectively indicate that this transition is M1 in character with less than 10% E2 admixture.

Antenatal glucocorticoids are administered to women at risk of preterm delivery to prevent neonatal respiratory morbidity. The effects of exogenous glucocorticoids on the development of lactation are unknown. This study investigated the effects of a single dose of antenatal glucocorticoids on secretory activation in sheep before and after parturition. Pregnant ewes (N=36) were randomised to receive either medroxyprogesterone acetate (MPA) at 118 days of pregnancy and betamethasone at 125 days (BETA group), MPA at 118 days and saline at 125 days (MPA group) or saline at 118 and 125 days (SALINE group). The concentration of lactose, progesterone, cortisol and prolactin in maternal plasma was measured during pregnancy. After term parturition, the concentration of lactose in milk and maternal plasma was measured daily for 5 days. Lambs were weighed at birth and at 5 days of age; milk volume was measured on day 5. The concentration of lactose in maternal plasma increased significantly after betamethasone administration, corresponding to a fall in plasma progesterone. No changes in lactose were observed in MPA or SALINE ewes. Transient decreases in cortisol and increases in prolactin were observed in the BETA group, but not in either the MPA or SALINE group. After parturition, BETA ewes experienced reduced milk yield and lamb weight gain, and delayed increases in milk lactose levels compared with MPA and saline controls. This study demonstrated that, in sheep, antenatal glucocorticoid administration disrupted secretory activation, causing precocious mammary secretion before parturition and compromising postpartum milk production and lamb growth.

Several Proteins, receptors, S proteins including s1 and s2 such as 6LU7, 6Q05, 4oW0, 6nur, 6Y84, 5zVK and 6vW1 were modeled and simulated via docking. All water molecules were deleted, then the covalently bound ligands were unbound from necessary places in those macromolecules including α, β double bond of the ligand, that behave as acceptors. The Structure Preparation modules of MOE were used to correct PDB inconsistencies and to assign the protonation state at biological ph. It is notable the structural knowledge of the CoV-RNA synthesis complexes was a structure of the NSP- RNA polymerase. Its structural gaps are containing information regarding the single N-terminal extension of the virus polymerases. CoV is partitioned into alpha, beta, gamma and delta categories. Among them the beta group initially consists of A, B, C, and D subunits.

Background: Beta-carotene (BETA) is a precursor of retinol (Vitamin A) and positively influenced on reproductive efficiency in cows. The aim of the study was to determine the effect of orally supplementation of beta-carotene on plasma carotene content and fertility rate of lactating crossbred Sahiwal cows. Methods: Twenty-four disease-free lactating crossbred Sahiwal cows with a close date of calving were randomly divided into two homogeneous groups for Control group (CONT; n = 12) and Beta-carotene group: 500 mg/cow/d (BETA; n = 12) from 7 days post partum (dpp) until 105 dpp thereafter on concentrations of beta-carotene and selected protein and energy parameters in plasma were determined. In addition, effects on fertility rate were studied. Result: Beta-carotene concentrations increased in plasma of beta-carotene (BETA-group) supplemented cows compared to control (CONT-group) cows (p less than 0.001). In BETA-group cows, urea concentration in blood plasma decreased significantly compared to cows of CONT-group (p less than 0.001) but did not differ in total protein, albumin, glucose and total cholesterol content in cows of both groups. Occurrence of first post partum estrus decreased (p less than 0.001) in beta-carotene (BETA-group: 74 dpp) cows compared to control (CONT-group: 81 dpp) cows. In this study, it was observed that the overall conception rate was higher (p greater than 0.001) in BETA-group: 83.33% (cows pregnant: 10/12) and lesser in the CONT-group: 50.00% (cows pregnant: 6/12). The results of this study indicated that oral supplementation with beta-carotene increased the concentration of beta-carotene and decreased the concentration of urea in plasma and cows with higher blood plasma beta-carotene content improved fertility over cows with lower blood plasma beta-carotene content.

Abstract Background Oral or intravenous beta-blockers have commonly been used to control the heart rate (HR) prior to coronary computed tomography angiography (CCTA). However, the administration after arrival at the hospital was time-consuming, and could not achieve the target heart rate in several cases. Moreover, the efficacy of transdermal beta blockers in HR control for patients who underwent CCTA have not been fully reported. Purpose The purpose of this study was to clarify the usefulness of the bisoprolol patch prior to the arrival at the hospital in HR control for patients who underwent CCTA. Methods A total of 282 consecutive patients (160 male, age 64±12 years) who underwent CCTA were included in this study. The bisoprolol transdermal patch (8mg) was administered before arrival at the hospital in 191 patients (beta group), and no additional medication was administered in 91 patients (control group). Intravenous landiolol hydrochloride was administered when HR remained over 65 bpm on arrival at the hospital. The HR on arrival, during and after CCTA was evaluated. Results The baseline HR was significantly higher in the beta group (80±15 vs. 72±15, P<0.0001). However, the achievement rate of HR ≤65 bpm on arrival was significantly higher in the beta group (56.5% vs. 44.0%, P=0.047). Thus, additional treatment with intravenous landiolol hydrochloride was administered to 43.5% of the patients in the beta group and 56.0% of those in the control group. There were no significant differences in the HR during and after CCTA between the 2 groups. Multivariate analysis revealed that the use of bisoprolol transdermal patch (OR, 3.54; 95% CI 1.67–7.51, P=0.001) and the baseline HR (OR, 0.91; 95% CI 0.89–0.94, P<0.0001) were significant predictors of the achievement rate of HR ≤65 bpm on arrival. There were no serious adverse effects throughout CCTA in all patients. Conclusions The administration of bisoprolol transdermal patch before arrival at the hospital was useful for HR control and reduced the rate of additional intravenous treatment in patients who underwent CCTA.

PURPOSE: To investigate the effect of recombinant human erythropoietin (epoetin beta) on anemia, transfusion need, and quality of life (QOL) in severely anemic patients with low-grade non-Hodgkin’s lymphoma (NHL), chronic lymphocytic leukemia (CLL), or multiple myeloma (MM). PATIENTS AND METHODS: Transfusion-dependent patients with NHL (n = 106), CLL (n = 126), or MM (n = 117) and a low serum erythropoietin concentration were randomized to receive epoetin beta 150 IU/kg or placebo subcutaneously three times a week for 16 weeks. Primary efficacy criteria were transfusion-free and transfusion- and severe anemia–free survival (hemoglobin [Hb] > 8.5 g/dL) between weeks 5 to 16. Response was defined as an increase in Hb ≥ 2 g/dL with elimination of transfusion need. QOL was assessed by the Functional Assessment of Cancer Therapy scale. RESULTS: Transfusion-free (P = .0012) survival and transfusion- and severe anemia–free survival (P = .0001) were significantly greater in the epoetin beta group versus placebo (Wald χ2 test), giving a relative risk reduction of 43% and 51%, respectively. The response rate was 67% and 27% in the epoetin beta versus the placebo group, respectively (P < .0001). After 12 and 16 weeks of treatment, QOL significantly improved in the epoetin beta group compared with placebo (P < .05); this improvement correlated with an increase in Hb concentration (≥ 2 g/dL). A target Hb that could be generally recommended could not be identified. CONCLUSION: Many severely anemic and transfusion-dependent patients with advanced MM, NHL, and CLL and a low performance status benefited from epoetin therapy, with elimination of severe anemia and transfusion need, and improvement in QOL.
