Guinea pig production systems demand organic alternatives to improve their productivity, due to the increased demands of this type of livestock operations. The present study aimed to evaluate the effect of organic acids on the productive and reproductive indices in reproductive Guinea pigs in an intensive breeding farm in Lima. 60 pools were used with 10 Guinea pigs in each one (9 females and one male).  They were randomly divided into 4 treatment groups: T1: 1mL/L, T2: 2mL/L, T3: 4mL/L; all with 15 pools in total (5 pools each with dosage of 5, 10 and 15 days, respectively), and T4: Control (15 pools without dosage); the observation period was 3 months. No significant difference was found (p> 0.05) between treatments for weight gain, percentage of maternal mortality, percentage of abortions, percentage of pregnancy, number of offspring born and percentage of viability. For the percentage of mortality of pups and average weight of the offspring, a significant difference was found (p <0.05), demonstrating that T3 reached a higher weight index at birth of offspring (T3: 147.7 / 142.7 / 146.8g) and lower percentage of mortality in rabbits (T3: 0 / 1.8 / 3.0%). No significant difference was found in terms of dosing days. It is concluded that supplementation with organic acids with T3 (4mL/L) improved the weight at birth of the offspring and the mortality percentage in kits.

A total of 28 male BALB/c mice (average weight 20.7 ± 1.6 g) were divided into 4 treatment groups and fed a commercial diet (A), a commercial diet + induced colitis by dextran sodium sulfate (DSS) (B),Inonotus obliquus(IO) administration (C), and IO administration + induced colitis by DSS (D). IO treatment (C, D) decreased the expression of tumor necrosis factor (TNF)-αand signal transducers and activators of transcription (STAT)1 compared to those of the colitis induced group (B). The expressions of IL-4 and STAT6 were decreased in group D compared to the colitis induced group (B). The serum immunoglobulin (Ig)E level decreased in IO treatment groups (C, D) compared to no IO treatment groups (A and B) although there was no significant difference between the IO treatment groups. Extract from IO itself had a weak cytotoxic effect on murine macrophage cell line (RAW264.7 cells). Extract from IO inhibited lipopolysaccharide- (LPS-) induced, TNF-α, STAT1, pSTAT1, STAT6, and pSTAT6 production in RAW264.7 cells.

The aim of this research is to analyze the effect of kebar grass on the diameter and epithelium thickness of seminiferous tubules. Twenty male mice of BALB/C strain with an average weight of 25 gram were used in this research. Total five experimental groups (4 mice each group) were treated with combination of TCDD and kebar grass extract designed as follows: (C-) 0mg/g BW/day dan 0µg/kg BW, (C+) 0mg/g BW/day and 7µg/kg BW, (T1) 0,045mg/g BW/day and 7µg/kg BW, (T2) 0,080mg/g BW/day and 7µg/kg BW, (T3) 0,1350mg/g BW/day and 7µg/kg BW. The TCDD was injected peritoneally in single dose while kebar grass extract was given orally everyday for 53 days. The results showed a significant difference (p<0,05) on group which is treated with kebar grass extract 0,135mg/ g BW/ day is proven could maintain the diameter of seminiferous tubules in T3 group (170,5μmb ± 0,65μm) compared with C+ group (129,50μma ± 8,42μm). Significant difference of epithelial thickness were also found between the control and treatment groups (p<0,05). The C+ group (33,57μmb ± 1,61μm) was different from the T1 group (43,80μmc ± 1,46μm), T2 (48,49μmd ± 1,08μm), T3 (52,15μme ± 0,86μm) and C- (56,17μma ± 1,35μm). This findings might suggest TCDD has the potential to decrease the epithelium thickness and the diameter of seminiferous tubules, while kebar grass extract in various dose were proven to be able maintain the epithelium thickness of seminiferous tubules but could not maintain the diameter of seminiferous tubules.

This experiment was conducted at the Animal Production Department farm to the College of Agriculture, University of Baghdad, located at Jadreya during the period of 21 September 2015 to 24 February 2016 using Four Awasi rams aged 2-4 years and the average weight was 52 kg. Semen collection from rams was done twice weekly by using the artificial vagina to study the effect of using the lactoferrin protein as a replacement by the antibiotic in the semen for controlling the contamination of bacteria in the semen. Four treated groups were used, the control (normal antibiotic Streptomycin 100 mg\100ml Penicillin 100.000 IU / 100ml) , second ,third and fourth treatment groups was used a lactoferrin  protein with the contamination of 400, 800 and 1200 mg \ L-1 , respectively . All additions of the antibiotic and lactoferrin were done to the semen after dilution. Semen from all rams was pooled and the final volume was divided by four parts to groups .The semen diluent was kept at the refrigerator 5 C for 5 days, and every day the physical characteristic was done which included. The individual motility, dead and abnormal sperm, concentration of sperm, mass activity, integrity of the plasma membrane (HOST %) The results showed that: the individual motility of sperm was significantly increased) for all treated groups on the second, third, fourth and the fifth day of semen preservation. No significant difference  in the percentage of live sperm as a result of adding lactoferrin to the semen. There were no significant increase) in the hyper osmotic sperm test (HOST%) between the control and treatment groups. The abnormality of sperm did not differ between the control and the treated groups.

An experiment is described which attempts to derive quantitative indicators regarding the potential relevance predictability of the intermediate stimuli used to represent documents in information retrieval systems. In effect, since the decision to peruse an entire document is often predicated upon the examination of one »level of processing« of the document (e.g., the citation and/or abstract), it became interesting to analyze the properties of what constitutes »relevance«. However, prior to such an analysis, an even more elementary step had to be made, namely, to determine what portions of a document should be examined.An evaluation of the ability of intermediate response products (IRPs), functioning as cues to the information content of full documents, to predict the relevance determination that would be subsequently made on these documents by motivated users of information retrieval systems, was made under controlled experimental conditions. The hypothesis that there might be other intermediate response products (selected extracts from the document, i.e., first paragraph, last paragraph, and the combination of first and last paragraph), that would be as representative of the full document as the traditional IRPs (citation and abstract) was tested systematically. The results showed that:1. there is no significant difference among the several IRP treatment groups on the number of cue evaluations of relevancy which match the subsequent user relevancy decision on the document;2. first and last paragraph combinations have consistently predicted relevancy to a higher degree than the other IRPs;3. abstracts were undistinguished as predictors; and4. the apparent high predictability rating for citations was not substantive.Some of these results are quite different than would be expected from previous work with unmotivated subjects.

SummaryThe efficacy of conventional dose adjusted oral anticoagulation for stroke prevention in patients with non-valvular atrial fibrillation is well- documented but not considered ideal as primary antithrombotic treatment in elderly patients. The antithrombotic effect of fixed minidose warfarin 1.25 mg/day alone or in combination with aspirin 300 mg/day, of conventional dose adjusted warfarin (INR 2.0-3.0), and of aspirin 300 mg/day have been investigated in outpatients with chronic nonvalvular atrial fibrillation in the second Copenhagen Atrial Fibrillation, Aspirin and Anticoagulant Therapy Study (AFASAK 2). In order to investigate the effect on the coagulation system of the treatments, the International Normalized Ratio of the prothrombin time (INR) and prothrombin fragment 1 + 2 (F1 +2) were monitored at baseline and after three months of treatment in 100 patients consecutively included in the trial. At baseline no differences in INR and F1+2 between the four treatment groups were present. After three months of therapy the level of INR increased significantly from baseline in patients receiving warfarin in any dose and the level of F1+2 decreased significantly by combined minidose warfarin-aspirin and by dose adjusted warfarin. When comparing the changes over time in FI +2 (three-month value minus baseline value) during therapy with fixed minidose warfarin, combined minidose warfarin-aspirin and aspirin alone no significant difference between the groups was found. In conclusion, INR was changed by all three warfarin regimens but only dose adjusted warfarin (INR 2.0-3.0) had a marked effect on F1+2.

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.

ObjectiveTo explore possible associations of treatment with biological disease-modifying antirheumatic drugs (bDMARDs), including T-cell-based and interleukin-6 inhibition (IL-6i)-based therapies, and the risk for type 2 diabetes mellitus (T2DM) in patients with rheumatoid arthritis (RA).Study design, setting and participantsFive treatment groups were selected from a United States Electronic Medical Records database of 283 756 patients with RA (mean follow-up, 5 years): never received bDMARD (No bDMARD, n=125 337), tumour necrosis factor inhibitors (TNFi, n=34 873), IL-6i (n=1884), T-cell inhibitors (n=5935) and IL-6i+T cell inhibitor abatacept (n=1213). Probability and risk for T2DM were estimated with adjustment for relevant confounders.ResultsIn the cohort of 169 242 patients with a mean 4.5 years of follow-up and a mean 641 200 person years of follow-up, the adjusted probability of developing T2DM was significantly lower in the IL-6i (probability, 1%; 95% CI 0.6 to 2.0), T-cell inhibitor (probability, 3%; 95% CI 2.3 to 3.3) and IL-6i+T cell inhibitor (probability, 2%; 95% CI 0.1 to 2.9) groups than in the No bDMARD (probability, 5%; 95% CI 4.6 to 4.9) and TNFi (probability, 4%; 95% CI 3.7 to 4.7) groups. Compared with No bDMARD, the IL-6i and IL-6i+T cell inhibitor groups had 37% (95% CI of HR 0.42 to 0.96) and 34% (95% CI of HR 0.46 to 0.93) significantly lower risk for T2DM, respectively; there was no significant difference in risk in the TNFi (HR 0.99; 95% CI 0.93 to 1.06) and T-cell inhibitor (HR 0.96; 95% CI 0.82 to 1.12) groups.ConclusionsTreatment with IL-6i, with or without T-cell inhibitors, was associated with reduced risk for T2DM compared with TNFi or No bDMARDs; a less pronounced association was observed for the T-cell inhibitor abatacept.

Abstract Background and purpose COVID-19 constitutes a worldwide threat, prompting Italian Government to implement specific measures on March 8, 2020, to protect patients and health workers from disease transmission. The impact of preventive measures on daily activity of a radiotherapy facility may hamper the ability to fulfill normal workload burden. Thus, we assessed the number of delivered treatments in a specific observation period after the adoption of preventive measures (since March 11 to April 24, 2020) and compared it with the corresponding period of the year 2019. Materials and methods Overall number of delivered fractions was related to actual time of platform daily activity and reported as a ratio between number of delivered fractions and activity hours (Fr/Hrs). Fr/Hrs were calculated and compared for two different periods of time, March 11–April 24, 2019 (Fr/Hrs1), and March 11–April 24, 2020 (Fr/Hrs2). Results Fr/Hrs1 and Fr/Hrs2 were 2.66 and 2.54 for year 2019 and 2020, respectively, for a Fr/Hrsratio of 1.07 (95% CI 1.03–1.12, p = 0.0005). Fr/Hrs1 was significantly higher than Fr/Hrs2 for SliR and PreciseR, with Fr/Hrsratio of 1.92 (95% CI 1.66–2.23, p < 0.0001) and 1.11 (95% CI 1.03–1.2, p = 0.003), respectively. No significant difference was reported for SynergyR and CyberknifeR with Fr/Hrsratio of 0.99 (95% CI 0.91–1.08, p = 0.8) and 0.9 (95% CI 0.77–1.06, p = 0.2), respectively. Fr/Hrs1 was significantly lower than Fr/Hrs2 for TomotherapyR, with Fr/Hrsratio of 0.88 (95% CI 0.8–0.96, p = 0.007). Conclusion Preventive measures did not influence workload burden performed. Automation in treatment delivery seems to compensate effectively for health workers number reduction.

Abstract Piglets raised in commercial production systems in the U.S. undergo painful management procedures, including surgical castration, tail docking and ear notching, without analgesia or anesthesia provision for pain relief. This is a significant animal welfare concern. There is an immediate need to identify the most practical and effective analgesia or anesthesia option for use on-farm. The objective of this study was to assess the efficacy of 2.0mg/kg firocoxib, administered to the sow and delivered transmammary to her piglets, and a vapocoolant spray (ethyl chloride) to reduce processing pain. Five-day old male and female Yorkshire-cross piglets were used. 2.0mg/kg firocoxib was administered to the sow intramuscularly 7h prior to processing piglets. An ethyl chloride spray was applied to the ears, tail and scrotum of the piglets immediately before ear notching, tail docking and surgical castration, respectively. Piglets were assigned to one of four treatment groups: firocoxib and vapocoolant spray (FV; n=32), firocoxib only (F; n=32), vapocoolant spray only (V; n=32), no treatment (CON; n=32). The observation period was from 24h pre- to 48h post-processing (specific time points = baseline, 0h, 1h, 2h, 4h, 7h, 24h, 30h, 36h, 48h). Preliminary results found piglets displayed significantly more pain-related behaviors at 24h and 30h post-processing than at most other time points (p&lt; 0.05). Piglets had significantly higher cranial temperatures at 7h post-processing than all other time points (p&lt; 0.05). There was a trend in FV and F piglets having a higher cranial temperature at 36h post-processing compared to V and CON piglets (p=0.08). All piglets had significantly higher hair cortisol levels at 4 vs 20-days old (p&lt; .0001); however, there were no significant treatment effects on cranial temperature, hair cortisol or pain behavior, suggesting firocoxib and the ethyl chloride spray were unable to significantly reduce piglet pain post-processing. Further study analysis is needed to confirm these initial findings.

Background: The aim of this study was to compare consequences in single and triple testicular biopsy by biopty gun in pubertal rats using histological and immunohistochemical analysis. Methods: Thirty-two Sprague-Dawley male rats were used as the experimental model. The rats were randomly divided into three study groups. The rats from the first group (n = 12) received a single-biopsy of upper pole of the left testis, while the rats from the second group (n = 10) received triple-biopsy of upper and lower poles and lateral surface of left testis. The third group (n = 10) was a control group. On the eightieth day after the biopsy in all rats bilateral orchiectomy and funiculectomy were performed to obtain testicular tissue and sperm for analysis. The consequences of the puncture were observed by pathohistology, immunohistochemistry and semen analysis. Results: The results of the study showed lower percentage of sperm count (14.5 mill/mL vs. 16 mill/mL, p = 0.130), sperm motility (24.6% vs. 32.7%, p > 0.05), abnormal sperm (30% vs. 27%, p > 0.05), atrophic tubules (21% vs. 6%, p < 0.001), volume (1.7 mL vs. 2.28 mL, p < 0.01) and apoptotic index (1.56 vs. 1.19, p = 0.650) in the testes with a triple-biopsy compared to the testes with a single-biopsy. Semen analysis showed a borderline significant difference between the group with triple-biopsy where sperm count was lower than it in the control group (14.5 mill/mL vs. 17.5 mill/mL, p = 0.05). A single-biopsy has little effect on the testis, especially on overall fertility. A triple-biopsy showed higher degree of the testicular damage but without a significant impact on overall fertility. Semen analysis showed that single- and triple-biopsies did not have a significant effect on sperm count, motility and morphology. Conclusion: Biopty gun procedure is a cheap, simple and reliable method for testicular biopsy in rats without a significant effect on sperm count, motility and morphology.
