Congenital blindness with ocular developmental anomalies, including retinal dysplasia, in Doberman Pinscher dogs
Authors: Bergsjø T. , Arnesen K. , Heim P. , Nes N. 
Published: February 2025

Summary
Hereditary, congenital blindness was studied in 15 Doberman Pinscher pups. The eyes were smaller than normal, and there was complete absence of the anterior chamber, aphakia, retinal detachment, and dysplasia as well as an irregular swelling and partial depigmentation of the retinal pigment epithelial cells. It was concluded that the condition was inherited as a recessive, autosomal trait.
Use of hyperimmune serum, vaccination, and certain management procedures for control of pseudorabies in swine
Authors: Hsu Frank S. , Lee Robert C. T. 
Published: February 2025

SUMMARY
A program involving use of hyperimmune serum, vaccination, and certain management procedures for the control of pseudorabies was evaluated on several farms on which the disease was enzootic. Neonatal mortality and reproductive failures on farms utilizing the program were compared with death losses and reproductive failures on farms not utilizing the program. The reduction in preweaning mortality and reproductive failures between the treated and non-treated groups were 42.1% and 39.6%, respectively.
Zinc deficiency in sheep and goats: Three field cases
Authors: Nelson D. R. , Wolff W. A. , Blodgett D. J. , Luecke B. , Ely R. W. , Zachary J. F. 
Published: February 2025

SUMMARY
Zinc deficiency was diagnosed in 2 flocks of sheep and a herd of goats. Alopecia and eating of wool were observed. Skin lesions were hyperkeratosis and parakeratosis. Abnormal hoof growth and a closed stance with arched back and bowed hindlimbs were seen. Anorexia, depression, and foot soreness diminished quickly after zinc supplementation. Skin lesions healed and hair and wool growth resumed. A cause for the deficiency could not be established.
Hyperosmotic oral replacement fluid for diarrheic calves
Authors: Jones R. , Phillips R. W. , Cleek J. L. 
Published: February 2025

SUMMARY
Twenty-five diarrheic neonatal calves, none of which was recumbent, were used to determine oral efficacy of a commercial product for fluid replacement, either by suckle or intubation. Changes in plasma protein, glucose, sodium, potassium, and osmolality as well as blood lactate and pcv were measured. Core body temperature and surface temperature at the hock and fetlock were monitored. Data were analyzed for interaction with time and response according to clinical condition. Significant differences (P< 0.05) following therapy were restricted to glucose and potassium changes. Beneficial posttreatment trends were observed in cutaneous temperature, blood lactate, plasma protein, and pcv values.
Pathologic findings in manatees in Florida
Authors: Buergelt Claus D. , Bonde Robert K. , Beck Cathy A. , O’shea Thomas J. 
Published: February 2025

Summary
Necropsy and microscopic examinations of 16 West Indian manatees (Trichechus manatus) revealed that the mortality of many of the animals was associated with environmental factors such as human-inflicted trauma and cold winters. Natural disease processes accounted for the death of only 1 manatee. In 3 manatees, the cause of death could not be determined.
Predisposition to invasive pneumococcal illness following parainfluenza type 3 virus infection in chimpanzees
Authors: Jones Ellen E. , Alford Patricia L. , Reingold Arthur L. , Russell Harold , Keeling Michael E. , Broome Claire V. 
Published: February 2025

Summary
An outbreak of invasive disease, including pneumococcal bacteremia, meningitis, and pneumonia, involved 17 of 83 (20.5%) chimpanzees at a primate rehabilitation unit. Invasive disease was more common in splenectomized than in nonsplenectomized animals (42.9% vs 18.4%), but the difference was not statistically significant. The outbreak followed closely an outbreak of upper respiratory tract infection (urti) that occurred with equal frequency in splenectomized and nonsplenectomized chimpanzees. Those with urti were 5.7 times as likely to develop invasive disease than those without urti (P<0.005). Fourteen of 20 (70%) chimpanzees with recent urti and serologically examined had a 4-fold or greater rise in titer to parainfluenza type 3 virus.
The outbreak of invasive disease occurred despite the fact that most of the chimpanzees had been vaccinated with pneumococcal vaccine. Efficacy of pneumococcal vaccine could not be demonstrated among any segment of the chimpanzee population, and testing of sera from 23 vaccinated chimpanzees against 4 pneumococcal serotypes (3, 6, 8, and 14) failed to show a meaningful immune response.
The findings demonstrated that viral urti can predispose primates to invasive infections and suggested that pneumococcal vaccine is not protective in chimpanzees.
An epidemiologic study of mortality in veal calves subsequent to an episode of zinc toxicosis on a California veal calf operation using zinc sulfate-supplemented milk replacer
Authors: Graham T. W. , Thurmond M. C. , Clegg M. S. , Keen C. L. , Holmberg C. A. , Slanker M. R. , Goodger W. J. 
Published: February 2025

Summary
Ninety-five 3- to 6-month-old male Holstein veal calves were evaluated after an episode of zinc toxicosis, to describe clinical signs and to identify management and/or host-related factors that may have contributed to death. Clinical signs appeared 23 days after feeding of milk replacer commenced. Of 85 calves examined, 64 had pneumonia (75.5%), 62 had ocular signs (72.9%), 46 had diarrhea (54.1%), 34 were anorectic (40.0%), 15 were bloated (17.6%), 8 had cardiac arrhythmias (9.4%), 3 had convulsions (3.5%), and 3 were polydipsic/polyphagic (3.5%). Clinical signs began to appear when calves each were being fed approximately 1.5 to 2.0 g of zinc/day and exposed to a cumulative zinc intake of 42 to 70 g, from a milk replacer containing 706 μg of elemental zinc/g of milk replacer. Of 95 calves studied, 1 died before zinc was supplemented, 16 died during the episode, 12 were euthanatized, 1 was lost to follow-up evaluation, 1 was culled, and 64 were slaughtered. Deaths attributable to zinc toxicosis were observed between 25 and 53 days after the milk replacer was supplemented with zinc. Calves died while being exposed cumulatively to 30 to 66 g of zinc. The factors of previous pneumonia severity, age, cumulative daily exposure (g) to zinc, and calf location within a bay were examined for possible associations with mortality, using stepwise logistic regression. Though younger calves tended to have a higher mortality than older calves, neither age category nor severity of pneumonia, before zinc supplementation, accounted for a significant mortality. Calves located in the front of a bay and fed first were 6.88 (95% CI = 1.41, 33.72) times more likely to die than were calves in the rear of a bay. When the variable location was included in the saturated logistic model, calves cumulatively exposed to 45 to 65 g of zinc were 60.87 (95% CI = 8.07, 458.58) times more likely to die than calves exposed to less than 45 g and were 362.12 (99% CI = 48.04, 2,729.00) times more likely to die than calves exposed to more than 65 g of zinc. High mortality of the intermediate (45 to 65 g) group was attributed to that group accumulating zinc at the highest rate, and having exceeded a threshold of toxicosis near 45 g.
Sagittal fractures of the third carpal bone in horses: 12 cases (1977–1985)
Authors: Fischer A. T. , Stover S. M. 
Published: February 2025

Summary
Third carpal sagittal fractures were found to be related to racing injuries in 10 of 12 horses. These fractures occurred most commonly on the medial aspect of the bone. A dorsoproximal-dorsodistal view of the carpus was required to visualize the fracture in all cases. Healing of the fracture required periods of rest of up to one year. Conservative management of these fractures resulted in return to function in 7 of 12 horses.
Cardiopulmonary and behavioral effects of fentanyl-droperidol in cats
Authors: Grandy J. L. , Heath R. B. 
Published: February 2025

Summary
The combination of the narcotic fentanyl (0.4 mg/ml) and the tranquilizer droperidol (20 mg/ml) was injected into 12 healthy adult cats at a rate of 1 ml/9 kg of body weight, sc. Arterial blood pressure, heart rate, respiratory frequency, PaCO2, and PaO2, arterial pH (pHa), and rectal temperature were measured before and 30, 60, 90, and 120 minutes after injection of fentanyl-droperidol. Respiratory frequency was decreased significantly (P<0.05) and heart rate increased significantly (P<0.05) at all measurement intervals after drug administration. Observed decrements in arterial blood pressure were not significant. Arterial PO2, PCO2, and pH did not change significantly. A significant (P<0.05) decrease in body temperature was measured 90 minutes after drug administration. All cats were calm, tractable, and frequently assumed lateral recumbency after administration of fentanyl-droperidol. This maximal tranquil state was determined to be 30 to 60 minutes after drug administration.
Partial mandibulectomy for treatment of mandibular fractures in dogs: Eight cases (1981-1984)
Authors: Lantz Gary C. , Salisbury S. Kathleen 
Published: February 2025

Summary
Partial mandibulectomy was performed in 8 dogs with open or infected mandibular fractures (3 second degree and 5 third degree) because of economic restriction, osteomyelitis, or severe bone and soft tissue injury. Six dogs ate voluntarily by the second day after surgery, and 2 dogs required pharyngostomy tube feeding for 2 to 6 days. Complications included oral wound dehiscence (3 dogs), shifting of the mandible toward the operated side (6 dogs), and drooping of the tongue (2 dogs). Slight malocclusion was of no consequence, and all dogs were eating normally at follow-up evaluations (10 days to 24 months; median, 13 months). Mandibular function was maintained in all dogs.
Toxicity of high doses of griseofulvin in cats
Authors: Kunkle Gail A. , Meyer Dennis J. 
Published: February 2025

Summary
Eight adult cats were treated with griseofulvin (110 to 145 mg/kg of body weight) daily for 11 weeks; 2 control cats were given a gelatin capsule daily. Hemograms and hepatic enzyme activities were monitored weekly for all cats. Bone marrow examinations were performed before administration of the drug and twice during the study. Cats were observed for untoward clinical effects. Signs of toxicosis (clinical, hematologic, or hepatic) were not found at any time during, or at the cessation of the study. Although the sample number of treated cats was small, it was concluded that hematologic or hepatic abnormalities that develop with the use of high-dose griseofulvin treatment may be an idiosyncratic reaction found only in a few cats.
Coxofemoral luxations in cattle: 22 cases (1980-1985)
Authors: Tulleners Eric P. , Nunamaker David M. , Richardson Dean W. 
Published: February 2025

Summary
Traumatic, unilateral coxofemoral luxation was diagnosed in 22 female dairy cattle (12 calves ≤13 months old, 10 adults). Physical examination differentiated between dorsal and ventral luxations, but could not distinguish luxations from fractures of the proximal aspect of the femur that occurred in 2 additional adults. Luxations were confirmed by radiography in 5 animals.
Closed reduction was accomplished in only 1 calf. A craniolateral surgical approach to the hip, using mechanically assisted traction, was successful in reducing 95% (20/21) of the luxations.
Craniodorsal luxations (16) were most common. Ninety-four percent of the animals were ambulatory before surgery. None had concomitant musculoskeletal injuries and 75% (12/16) survived for a long period. Five of 6 animals with ventral luxations arrived recumbent, with serious complicating musculoskeletal injuries, and only 2 of these animals survived for a long period.
Calves had a better long-term survival rate (75% vs 50%) and a lower reluxation rate (17% vs 40%), compared with adults.
Vertebral canal and spinal cord mensuration: A comparative study of its effect on lumbosacral myelography in the Dachshund and German Shepherd Dog
Authors: Morgan Joe P. , Atilola Matthew , Bailey Cleta Sue 
Published: February 2025

Summary
One hundred noncontrast spinal radiographic studies followed by myelography were evaluated to compare vertebral canal size and spinal cord location and size in a chondrodystrophic breed (50 Dachshunds) with those variables in a nonchondrodystrophic breed (50 German Shepherd Dogs). Measurements were made of the sagittal diameter (height) of the vertebral canal, sagittal diameter (height) of the spinal cord, and transverse diameter (width) of the spinal cord in the lumbar and sacral regions. Differences were detected in the craniocaudal location of maximal vertebral canal height and maximal spinal cord height. The spinal cords in the Dachshunds terminated further caudally than those in the German Shepherd Dogs. Location of maximal spinal cord width was different between the breeds, consistent with the apparent, more caudal termination of the cord in the Dachshunds. The ratio of spinal cord to vetebral canal heights was notably greater in the Dachshunds than in the German Shepherd Dogs. These differences in vertebral canal and spinal cord mensuration may influence the choice of radiographic technique and its interpretation. Injection sites may be selected further cranially in German Shepherd Dogs (L4-5) than in Dachshunds (L5-6).
The economic benefit of treating subclinical Streptococcus agalactiae mastitis in lactating cows
Authors: Yamagata M. , Goodger W. J. , Weaver L. , Franti C. 
Published: February 2025

Summary
The economic benefits of treating lactating cows for Streptococcus agalactiae mastitis were studied at a large (689 milking cows) central California dairy. Postcure milk production of case cows (infected, treated, and cured) was compared with production of paired control cows (uninfected) and was matched for yield, days in milk, days in gestation, and parity. A simulation was used to plot expected lactation curves for mastitic cows (infected, not treated) with characteristics similar to those of each control cow, and these curves were compared with actual case-cow lactation curves. The difference in actual and expected production was used to calculate net economic benefits of treatment.
Comparison of expected with actual production indicated a net benefit from treatment of $396/cow for cows treated in early lactation and $237 for cows treated in midlactation, but a net loss of $55 for cows treated in late lactation. Lactation number did not have a significant impact on economic benefits of treatment.
In contrast to other studies indicating no economic benefit from treating mastitis during lactation, this study’s positive results may have been attributable to the high cure rate (98%) and the subclinical form of mastitis being treated. Streptococcus agalactiae mastitis treatment during early and midlactation would appear to be an economically justifiable option for dairy managers.

A new class of unsaturated mappings: Ćirić-Reich-Rus contractions
Authors: Berinde Vasile , Păcurar Mădălina 
Published: February 2025

Abstract
Using the technique of enriching contractive type mappings, we introduce a more general concept of enriched Ćirić-Reich-Rus contraction than the one studied in [Berinde, V.; Păcurar, M. Fixed point theorems for enriched Ćirić-Reich-Rus contractions in Banach spaces and convex metric spaces. Carpathian J. Math.
37 (2021), no. 2, 173–184.] and provide convergence results for the Krasnoselskij iterative algorithm used to approximate their fixed points. Examples to illustrate the effectiveness of the new results as well as comparison to other classes of contractive type mappings existing in literature are also presented. In this context, we also conclude that Ćirić-Reich-Rus contractions form a class of unsaturated mappings.
Finite-dimensional Zinbiel algebras and combinatorial structures
Authors: Ceballos Manuel , Núñez Juan , Tenorio Ángel F. 
Published: February 2025

Abstract
In this paper, we study the link between finite-dimensional Zinbiel algebras and combinatorial structures or (pseudo)digraphs determining which configurations are associated with those algebras. Some properties of Zinbiel algebras that can be read from their associated combinatorial structures are studied. We also analyze the isomorphism classes for each configuration associated with these algebras providing a new method to classify them and we compare our results with the current classifications of 2- and 3-dimensional Zinbiel algebras. We also obtain the 3-vertices combinatorial structures associated with such algebras. In order to complement the theoretical study, we have designed and performed the implementation of an algorithm which constructs and draws the (pseudo)digraph associated with a given Zinbiel algebra and, conversely, another procedure to test if a given combinatorial structure is associated with some Zinbiel algebra.
Operational matrix method to solve nonlinear reaction-advection-diffusion equation in fractional order system
Authors: Craciun E-M. , Singh M. 
Published: February 2025

Abstract
In the present paper, a numerical scheme is discussed to solve one-dimensional nonlinear diffusion equation of fractional order in which collocation is performed using the Lucas operational matrix. Since the spectral collocation method is used in the proposed method, therefore the residual, initial and boundary conditions of the presented problem are collocated at fixed collocation points. The result is a system of nonlinear equations that can be solved by using Newton’s method. Through error analysis and application to some existing problems, the accuracy of the method is confirmed. The obtained results are presented in tabular forms, which clearly show the higher accuracy of the proposed method. The variations of the solute profile of the proposed model are shown graphically due to the presence or absence of advection and reaction terms for different particular cases.
On (1,2)-absorbing primary ideals and uniformly primary ideals with order ≤ 2
Authors: Alhazmy Khaled , Almahdi Fuad Ali Ahmed , Bouba El Mehdi , Tamekkante Mohammed 
Published: February 2025

Abstract
This paper introduces a subset of the set of 1-absorbing primary ideals introduced in [3]. An ideal I of a ring R is (1,2)-absorbing primary if, whenever non-unit elements α, β, γ ∈ R with αβγ ∈ I,then αβ ∈ I or γ
2 ∈ I. The introduced notion is related to uniformly primary ideals introduced in [5]. The first main objective of this paper is to compare (1,2)-absorbing primary ideals with uniformly primary ideals with order less than or equal 2, as well as to characterize them in many classes of rings. The second part of this paper characterizes, by using (1,2)-absorbing primary ideals, the rings R for which all ideals lie between N(R) (the nil-radical of R)and N(R)2.
Green-Lindsay thermoelasticity for double porous materials
Authors: Emin Anamaria N. , Florea Olivia A. 
Published: February 2025

Abstract
The main purpose of this paper is to obtain new results in the thermoelasticity for double porous materials, starting from the classical theory of Green-Lindsay’s elasticity. The novelty of the proposed method consists in proving a reciprocal theorem and obtaining the energy equation in the context of Green-Lindsay’s thermoelasticity for double porous materials. The added value in this article is the result regarding the uniqueness of the solution of the problem with mixed data for bodies with double porosity.
Weighted pseudo almost automorphic functions with applications to impulsive fractional integro-differential equation
Authors: Kavitha Velusamy , Arjunan Mani Mallika , Baleanu Dumitru , Grayna Jeyakumar 
Published: February 2025

Abstract
This paper’s main motivation is to study the notion of weighted pseudo almost automorphic (𝒲𝒫𝒜𝒜) functions and establish the existence results of piecewise continuous mild solution of fractional order integro-differential equation with instantaneous impulses. The usual 𝒲𝒫𝒜𝒜 functions may not work since the solution of impulsive differential equations may not be continuous. Thus in order to give a broader spectrum, we introduce this concept. We establish main results by using the Banach contraction mapping principle and Sadovskii’s fixed point theorem. An example is shown to exhibit our analytic findings.
Predictability and uniqueness of weak solutions of the stochastic differential equations
Authors: Merkle Ana 
Published: February 2025

Abstract
Causality is a topic which receives much attention nowadays and it represents a prediction property in the context of possible reduction of available information in order to predict a given filtration. In this paper we define the concept of dependence between stochastic processes and between filtrations, named causal predictability, which is based on the Granger’s definition of causality. This definition extends the ones already given in the continuous time. Then, we provide some properties of the given concept.
Finally, we apply the concept of causal predictability to the processes of the diffusion type, more precisely, to the uniqueness of weak solutions of the stochastic differential equations.

A Voronovskaja type theorem will be proved as well.
Regular and Boolean elements in hoops and constructing Boolean algebras using regular filters
Authors: Aaly Kologani M. , Jun Y.B. , Borzooei R.A. 
Published: February 2025

Abstract
We study hoops in order to give some new characterizations for regular and Boolean elements in hoops and we study the relationship between them. Specially, we prove that any bounded v-hoop is a Stone algebra if and only if MV -center set and Boolean elements set are equal. Then we define the concept of regular filter in hoops and v-hoops with RF-property and peruse some properties of them. In addition, we show that each v-hoop with RF-property, is a Boolean algebra and any hoop A with RF-property such that B(A) = {0, 1}, is a local hoop. Finally, we prove that any hoop A has RF-property if and only if Spec(A) = Max(A) and if and only if A is a hyperarchimedean.
