Pengaruh Perbedaan Jenis Kelamin dan Kastrasi Pada Kambing Kacang terhadap Perubahan Lingkar dan Lebar Dada yang Dihasilkan

Penelitian ini bertujuan untuk mengetahui perubahan lingkar dada dan lebar dada yang dihasilkan Kambing Kacang berdasarkan perbedaan jenis kelamin dan kastrasi. Penelitian berlangsung pada bulan Juni-September 2021, bertempat di kandang Fakultas Pertanian, Universitas Timor. Ternak yang digunakan adalah 15 ekor kambing yang terdiri dari Kambing Kacang kastrasi 5 ekor, kambing betina tanpa kastrasi 5 ekor, dan kambing betina 5 ekor. Metode yang digunakan dalam penelitian ini merupakan metode rancangan acak lengkap (ANOVA). Hasil penelitian menunjukkan bahwa rata-rata lingkar dada kambing kastrasi 0,04±0,11, lingkar dada kambing jantan tanpa kastrasi 0,08±0,11, dan lingkar dada kambing betina 0,04±0,10. Selanjutnya, rata- rata lebar dada kastrasi 0,02±0,04, kambing jantan tanpa kastrasi 0,02±0,04, dan kambing betina 0,02±0,04. Disimpulkan bahwa Kambing Kacang jantan kastrasi, jantan non kastrasi, dan kambing betina yang diberikan complete feed menghasilkan lingkar dada dan lebar dada yang relatif sama

Enterococcus faecalis Endocarditis After Endoscopic Mucosal Resection of a Large Sessile Colonic Polyp

A 71-year-old man with mitral regurgitation and apical cardiomyopathy underwent endoscopic mucosal resection of a 22-mm transverse colon tubulovillous adenoma with high-grade dysplasia. Six weeks later, he presented with fever, valvular vegetations, and positive blood cultures for Enterococcus faecalis. To our knowledge, this is the first reported case of endocarditis involving native heart valves after endoscopic mucosal resection

Flight Initiation Distance Differs Between Populations of Western Fence Lizards (Sceloporus occidentalis) at a Rural and an Urban Site

Abstract.—Flight initiation distance (FID) is the distance to which a predator is permitted to approach before the prey initiates flight behavior. This can be influenced by factors including predator density and distance to cover. We measured flight initiation distances in two populations of Western fence lizards (Sceloporus occidentalis), one in a rural and one in an urban environment. Lizards at the rural site initiated flight at significantly longer distances than those at the urban site. These results support the prediction that lizard behavior can be influenced by differences in human exposure and predator recognition in their environments. Lizards develop tolerance to humans in urban areas in order to maximize fitness by reserving energy and utilizing resources for longer periods of time. The findings from this study demonstrate that researchers should be aware of differences in human exposure between populations of study animals and should choose study sites appropriately when designing FID studies

The role of fat mass index in determining obesity

Objectives: The objective of this study is to compare body mass index (BMI), percent body fat (PBF), and fat mass index (FMI) and to investigate the accuracy of FMI as a convenient tool for assessing obesity. Design: Anthropometric measurements and bioelectrical impedance analyses were performed on 538 Mexican Americans (373 women and 165 men). Correlations between BMI and PBF and between FMI and PBF were investigated. The percentage of persons misclassified as obese using different classifications was calculated. Multiple linear regression analysis was performed to generate predictive models of FMI for males and females separately. Results: BMI and PBF were correlated in men (rho = 0.877; P \u3c 0.0001) and women (rho = 0.966; P \u3c 0.0001); however, 20 and 67.2% of the men and 9.2 and 84.2% of women, classified as normal weight and overweight by BMI, respectively, were diagnosed as obese by PBF. FMI and PBF were also correlated in men (rho = 0.975; P \u3c 0.0001) and women (rho = 0.992; P \u3c 0.0001). Four percent of the men classified as normal weight and 65.5% classified as overweight by BMI were obese by FMI, while 71.3% of women classified as overweight by BMI were obese by FMI. Misclassification of obesity between FMI and PBF categories was observed in 5.4% of men and 7.8% of women. Conclusions: The discrepancy observed between BMI and PBF reflects a limitation of BMI. Conversely, FMI accurately assessed obesity in our study of Mexican Americans, but further studies are necessary to confirm our findings in different ethnic groups

Hyperfine interaction and magnetoresistance in organic semiconductors

We explore the possibility that hyperfine interaction causes the recently discovered organic magnetoresistance (OMAR) effect. Our study employs both experiment and theoretical modelling. An excitonic pair mechanism model based on hyperfine interaction, previously suggested by others to explain magnetic field effects in organics, is examined. Whereas this model can explain a few key aspects of the experimental data, we, however, uncover several fundamental contradictions as well. By varying the injection efficiency for minority carriers in the devices, we show experimentally that OMAR is only weakly dependent on the ratio between excitons formed and carriers injected, likely excluding any excitonic effect as the origin of OMAR.Comment: 10 pages, 7 figures, 1 tabl
