Abstract The objective of this study was to determine the effect of two commercial mineral supplements on ewes/lamb pairs DMI and ADG. All ewes prior to lambing were maintained a sheep pellet formulated for no mineral, vitamin, or probiotic content at a rate of 2% body weight, ad libitum Bermuda hay, and ad libitum access to the control mineral supplement. Ewe/lamb pairs were randomly assigned based on twining and parity to study groups four days post-lambing. The treatment (TRT) group had 12 ewes/18 lambs, and a control (CNTRL) group had 11 ewes/17 lambs, and was conducted over 6wks. Lambs in both groups were offered ad libitum alfalfa via a creep feeding gate. The TRT group received a commercial chelated mineral mix that included Ascophyllum nodosum seaweed extract in the blend and the CNTRL received a commercial non-chelated mineral without seaweed extract. Chelated minerals were Cu, Mn, and Zn. Daily feed and ort samples were collected 2x week and dried at 55℃ for analysis. Feed was adjusted daily to maintain a 3–5% refusal rate. Samples were compiled by week and analyzed for DM, Ash, aNDF, aADF, EE, and CP. Blood samples were collected from a subset of 7 ewes per group, 3x during the study (wk1, wk3, wk6) for later trace mineral analysis (Co, Cu, Fe, Mn, Mo, Se). Results indicate a significant difference in mineral DMI between groups (P = 0.03), but no significant impact on DMI of Bermuda or alfalfa. ADG for lambs was numerically increased 0.25±0.01 TRT versus 0.23±0.01 kg CNTRL but was not statistically significant (P = 0.18). No significant differences in trace mineral levels between groups or over time were seen. All mineral levels were in the normal range for both groups. It appears the addition of the chelated mineral with Ascophyllum nodosum seaweed extract did not improve ADG or DMI, but the results of this study were potentially affected by severe weather conditions. Further study is needed under more favorable conditions to confirm product impacts in ewe/lamb pairs.

The aim of the study was to study the headache features in patients with dyscirculatory encephalopathy of different genesis. Materials and methods: Clinical-neurological and clinical-instrumental examination of 90 persons aged 40 to 68 was performed. The first group consisted of 60 patients with dyscirculatory encephalopathy and arterial hypertension (DE and AH), the second group – 30 patients with dyscirculatory encephalopathy and cerebral atherosclerosis (DE and CA). Results: In the study of headache in patients with DE + AH and DE + CA, the frequency of detection, the intensity on the VAS scale, and the nature of the headache, no significant difference was found between study groups. Conclusions: According to the results of the study, it was proved that patients with DE + CA had headache in the root area, with the circumstances of headache being significantly outweighed «for no apparent reason» (p = 0.007) and with changing weather conditions (р = 0.001). Arterial hypertension was a major factor in headache (p = 0.008) and in patients with DE + AH.

Thirteen South Australian strong-wool Merino ewes and eight Border Leicester × Merino ewes mated to Poll Dorset rams were fed on lucerne pellets ad libitum during late pregnancy and lactation in pens. Each of their single-born progeny was slaughtered at 33 kg full liveweight. Breeds were compared for efficiency of the ewe (organic matter intake per unit liveweight and clean wool per unit intake), efficiency of the lamb (liveweight and body solids gain per litre of milk), and efficiency of the ewe-lamb unit (liveweight and carcass weight per unit intake). Border Leicester × Merino ewes ate 7% less organic matter per unit liveweight than Merino ewes during lactation; however, there was no significant difference during late pregnancy. In terms of absolute intake 120 Merinos = 100 Border Leicester × Merinos. Border Leicester × Merino ewes were 73% as efficient in converting feed to clean wool as Merino ewes. Merino ewes grew wool of smaller diameter and higher crimp frequency than crossbreds. Lambs from the Merino ewes were as efficient in converting milk into animal tissue as the progeny from Border Leicester x Merino ewes during the first 4 weeks of suckling. Lambs from Merino ewes required on average 25 extra days to grow to the same slaughter weight and ate 110% more organic matter from solid feed than lambs from crossbred ewes. However, the proportion of feed eaten by the lamb was small (10%) compared with that eaten by the ewe. Lambs from crossbred ewes were 23% heavier than those from Merino ewes at the same age. The crossbred ewe-lamb unit, however, consumed 20% more feed and hence was as efficient as the Merino ewe–lamb unit. The Merino ewe–lamb unit was more efficient than the crossbred ewe-lamb unit when the lamb genotypes were slaughtered at the same liveweight (P < 0.05); however, the difference was not significant when expressed as carcass weight per unit intake.

Abstract A study was conducted in fall 2019 at Sul Ross State University to evaluate the effects of Total Equine™ containing Ascophyllum nodosum seaweed and chelated minerals on intake and cecal digestibility in comparison to a product without Ascophyllum nodosum seaweed or chelated minerals. Six quarter horse mares (avg 9 yrs) were used in a complete randomized block study. Horses were offered an ad libitum Bermuda hay for a 2wk standardization period and then blocked into pairs based on weight, age, and fitness level. Horses were assigned randomly within block to the Ctrl or Trt diets for an 8wk study with ad libitum access to water. Hay was offered 2xd in port-a-grazer tubs to control for waste. Grain was offered at a rate of 0.5% BW (manufacturer suggestions) and divided into 2 equal feedings. Horses were weighed weekly and grain amounts were adjusted weekly. Hay orts were collected 2x daily and hay offered was adjusted daily for a 3% refusal rate. Horses were exercised 6 d/wk on a hot-walker for 2 hrs. Horses were conditioned prior to the study and speed and duration were increased throughout the study. Horses worked 30 min at a walk and 1.5 hrs at a trot broken into periods. Feed samples were collected 2xwk and dried for DM and ground for analysis for NDF, ADF, CP, EE, and Ash. Blood samples were collected for 3x (1 wk, 4 wk, 8 wk) pre/post exercise to be tested for cortisol levels. A significant difference in total DMI was observed at 13.1 ± 0.14 kg Ctrl versus 12.02 ± 0.11 kg Trt (P = 0.0001). When looking at forage intake only 10.07 ± 0.13 kg Ctrl versus 9.04 ± 0.11 kg Trt (P = 0.0001). Overall, it appears that the inclusion of the grain product with Ascophyllum nodosum and chelated minerals reduced forage intake and overall DMI without affecting weight or animal performance.

Background: Although cardiac resynchronisation therapy (CRT) is an important player in the treatment of heart failure (HF) patients, the proportion of CRT patients with no improvement in either echocardiographic or clinical parameters remains consistently high and accounts for about 30% despite meeting CRT implantation criteria. Furthermore, in patients suffering from HF, renal dysfunction accounts for as many as 30-60%. Accordingly, CRT may improve renal function inducing a systemic haemodynamic benefit leading to increased renal blood flow. Objectives: The aim of the present study was to evaluate the importance of renal function in response to resynchronisation therapy during a 12-month follow-up period. Materials and methods: The study consisted of 46 HF patients qualified for implantation of cardiac resynchronisation therapy defibrillator (CRT-D). A CRT responder is defined as a person without chronic HF exacerbations during observation whose physical efficiency has improved owing to New York Heart Association (NYHA) class improvement ≥1. Results: A statistically significant difference was noted between responders and non-responders regarding creatinine level at the 3rd month (p=0.04) and, particularly, at the 12th month (p=0.02) of follow-up (100±23 vs 139±78 μmol/l). Moreover, there was a remarkable difference between both study groups with regard to GFR CKD-EPI (glomerular filtration rate (GFR) assessed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula) at the 6th (p=0.03) and 12th month (p=0.01) of follow-up. The reference values for initial creatinine concentrations (101 μmol/l) as well as GFR CKD-EPI (63 ml/min/1.73m2 ) were empirically evaluated to predict favourable therapeutic CRT response. Conclusions: Predictive value of GFR CKD-EPI and creatinine concentration for a positive response to CRT were found relevant.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract Background The immune mechanisms that determine whether a Plasmodium falciparum infection would be symptomatic or asymptomatic are not fully understood. Several studies have been carried out to characterize the associations between disease outcomes and leucocyte numbers. However, the majority of these studies have been conducted in adults with acute uncomplicated malaria, despite children being the most vulnerable group. Methods Peripheral blood leucocyte subpopulations were characterized in children with acute uncomplicated (symptomatic; n = 25) or asymptomatic (n = 67) P. falciparum malaria, as well as malaria-free (uninfected) children (n = 16) from Obom, a sub-district of Accra, Ghana. Leucocyte subpopulations were enumerated by flow cytometry and correlated with two measures of parasite load: (a) plasma levels of P. falciparum histidine-rich protein 2 (PfHRP2) as a proxy for parasite biomass and (b) peripheral blood parasite densities determined by microscopy. Results In children with symptomatic P. falciparum infections, the proportions and absolute cell counts of total (CD3 +) T cells, CD4 + T cells, CD8 + T cells, CD19 + B cells and CD11c + dendritic cells (DCs) were significantly lower as compared to asymptomatic P. falciparum-infected and uninfected children. Notably, CD15 + neutrophil proportions and cell counts were significantly increased in symptomatic children. There was no significant difference in the proportions and absolute counts of CD14 + monocytes amongst the three study groups. As expected, measures of parasite load were significantly higher in symptomatic cases. Remarkably, PfHRP2 levels and parasite densities negatively correlated with both the proportions and absolute numbers of peripheral leucocyte subsets: CD3 + T, CD4 + T, CD8 + T, CD19 + B, CD56 + NK, γδ + T and CD11c + cells. In contrast, both PfHRP2 levels and parasite densities positively correlated with the proportions and absolute numbers of CD15 + cells. Conclusions Symptomatic P. falciparum infection is correlated with an increase in the levels of peripheral blood neutrophils, indicating a role for this cell type in disease pathogenesis. Parasite load is a key determinant of peripheral cell numbers during malaria infections.
