Efficacy Of Repeatedly Used Cidr Device In Cattle Reproduction: A Metaanalysisreview Of Progesterone Concentration And Conception Rate, Muhammad Furqan Asghar Chacher, Armağan Çolak, Armağan Hayirli Jan 2017

Efficacy Of Repeatedly Used Cidr Device In Cattle Reproduction: A Metaanalysisreview Of Progesterone Concentration And Conception Rate, Muhammad Furqan Asghar Chacher, Armağan Çolak, Armağan Hayirli

Turkish Journal of Veterinary & Animal Sciences

n order to reduce estrus synchronization cost, utilization of residual progesterone (P4) in the used controlled internal drug release (CIDR) device upon sanitization can be possible. Two datasets were compiled from 8 and 7 research articles involving 3434 (2653 heifers + 771 lactating cows + 10 ovariectomized cows) and 7301 cattle (3879 heifers + 3422 lactating cows) to evaluate blood P4 concentration and conception rate, respectively, in response to repeatedly used CIDR devices after sanitization via autoclaving and disinfection. As the number of CIDR usages increased, blood P4 concentration decreased linearly (y = -0.484X + 3.135, R2 = 0.99, P < 0.001). Blood P4 concentration (1.52 vs. 2.20 ng/mL; P < 0.002) and conception rate (40.76 vs. 32.96%, P < 0.05) for lactating cows were lower than those for heifers. The sanitization method did not affect blood P4 concentration, but reused CIDR device subjected to disinfection was associated with reduced conception rate. In summary, depending upon the initial P4 load (1.38-1.90 g), the CIDR device could be used twice in lactating cows and four times in heifers after autoclaving to achieve target blood P4 concentrations.

The “Precautionary Principle” – A Work In Progress, Shelley Adamo Jan 2017

The “Precautionary Principle” – A Work In Progress, Shelley Adamo

Animal Sentience

The target article by Birch illustrates the practical difficulties with the “Animal Sentience Precautionary Principle” (ASPP) while presenting potential solutions. However, the ASPP will be difficult to use without guidelines detailing how evidence of sentience should be assessed. Moreover, extrapolating conclusions found for a single species to all species within an Order is problematic. Finally, I recommend that Birch demonstrate his ASPP framework using a controversial test case to help show how it could be used in real-world situations.

What If All Animals Are Sentient?, Arthur S. Reber Jan 2017

What If All Animals Are Sentient?, Arthur S. Reber

Animal Sentience

Birch develops a useful framework for determining when the Animal Sentience Precautionary Principle (ASPP) should be invoked. He rightly notes that there is a lack of agreement among social scientists, ethicists, and legislators even about whether the precautionary principle is useful, let alone when and how it should be implemented. His proposal is to establish a kind of cognitive threshold, and only when an animal shows a sufficient level of sentience would the ASPP be appropriate. From the point of view of the Cellular Basis of Consciousness model (Reber, 2016), all animals are sentient. If correct, the problems Birch identifies …

Cognitive Dissonance Or Contrast? It Could Be Both, Thomas Zentall Jan 2017

Cognitive Dissonance Or Contrast? It Could Be Both, Thomas Zentall

Animal Sentience

My target article suggested that cognitive dissonance may be accounted for by a simpler mechanism: contrast. Whether contrast can explain all cognitive dissonance effects is an empirical question, but it is always useful to try to distinguish simpler mechanisms from more complex cognitive ones. The insistence that cognitive dissonance is a human-only process quite different from contrast may be a self-serving means of justifying the exploitation of animals.

Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka Jan 2017

Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka

University of the Pacific Theses and Dissertations

Dirofilaria immitis Leidy (dog heartworm) is a life-threatening parasite transmitted by mosquitoes to domestic dogs. Endemic in the eastern United States, cases have become more prevalent over the last few decades. While prevalence in California is generally low, Lake and San Joaquin Counties have reported rates comparable to the East Coast at 3.73% and 0.71%(CAPC 2017), respectively. Aedes sierrensis is thought to be responsible for transmission in California, but in some cases, it exists in inadequate quantities and temporal ranges to explain parasite activity. Based on Huang et al. (2013) and Tran (2016), bloodfeeding patterns, and other vector criteria, Culex …

Effects Of Aluminum, Copper, And Titanium Nanoparticles Onsome Blood Parameters In Wistar Rats, Esi̇n Gülnaz Canli, Mustafa Canli

Turkish Journal of Zoology

In this study, Al2O3, CuO, and TiO2 nanoparticles (NPs) were individually administered to 60 mature female rats via oral gavage (0, 0.5, 5, and 50 mg/kg b.w. per day) for 14 days and then responses of ATPases in the erythrocytes, total oxidant status (TOS), total antioxidant status (TAS), and liver enzyme (alkaline phosphatase, ALP; alanine transaminase, ALT; aspartate transaminase, AST) levels in the serum were determined. There were sharp decreases in Na,K-ATPase activity in the erythrocytes following NP exposures. All doses of CuO caused significant (P < 0.05) inhibitions in Na,K-ATPase activity (up to 94%), while only higher doses of Al2O3 and TiO2 inhibited (76%-80%) the activity of Na,K-ATPase. Oppositely, the activities of Ca-ATPase (up to 274%) and Mg-ATPase (up to 290%) increased significantly following TiO2 exposures. TOS levels significantly increased following Al2O3 (167%) and CuO (240%) exposures, though TAS levels did not change significantly in any of the exposure groups. The levels of ALP, AST, and ALT increased following NP administrations. Ti-NP increased the levels of all liver enzymes in the serum (up to 84%), while Al-NP (58%) and Cu- NP (43%) increased only ALP levels. The present study demonstrated evidence of the toxic effects of NPs, as they altered the measured parameters in the blood, and suggests further research to better understand the environmental fate of NPs.
