The poultry industry suffers from various diseases or stresses. In poultry, apart from being antipyretic, acetylsalicylic acid (ASA) is widely used to cope with different issues including heat stress, and respiratory and digestive orders. This study evaluated the beneficial and toxic effects of ASA at different dose levels in broiler birds. To evaluate these toxic and beneficial effects it is necessary to examine the physical and serum biochemical parameters as well as the histopathological changes with tissue sections taken from broiler birds under experimental trial. This study was conducted on 60 one-day-old broiler chicks purchased from a local market in Faisalabad. Chicks were reared for the first 14 days under similar conditions. On the 15th day, birds were randomly divided into 4 groups (1-4) with 15 birds in each group. Group 4 was kept as control, while groups 1, 2, and 3 were treated with ASA at the dose of 300, 600, and 1200 mg/L of drinking water for 21 days. There were 3 samplings performed at 21, 28, and 35 days post-treatment. The live body weight and carcass weight were noted on each sampling. All the visceral organs were recorded for gross pathological changes. The serum samples were collected for biochemical evaluation. Histopathology of all the visceral organs was performed to observe the microscopic changes. A significant (P<0.05) increase in live body weight at a 300mg/L dose was noted after the first 2 samplings. A significant (P<0.05) increase in the relative organ weight was recorded at 1200 mg/L. The groups treated with ASA 600 and 1200 mg/L showed increased (P<0.05) AST, ALT, and creatinine levels from that of the control group. The group treated with 1200 mg/L of ASA showed increased (P<0.05) urea, serum total protein, and albumin level in all the samplings. Histopathological changes revealed swollen hepatocytes, increased sinusoidal spaces in the liver, congestion and abnormal glomerular spaces in the kidney, congestion and alveolar disruption in the lungs, and generation of villi and cellular degeneration in the intestine in a high-dose group. The study concluded that ASA at a low dose can be used for a long time in broilers and has a growth promontory role, while high-level doses cause hepatorenal toxicity.

In breast cancer treatment, chemotherapy resistance is a major problem where many receptive tumors rebound and develop resistance. When provided in combination, cancer drugs are most successful, thus reducing the risk of developing resistant cancer cells. However, the evaluation of combination therapies has increased rapidly in recent years. Consequently, by repurposing old treatments, the discovery of additional medicines that may interact synergistically with chemotherapy is considered a current medical aim through discovering a new cancer medication or therapeutic strategy. The purpose of this research is to increase the anti-cancer activity of carboplatin (CP) by increasing the apoptotic effect of breast cancer cells (MCF-7) during in vitro experiments in combination with oxytetracycline. Our results showed a high synergistic effect between oxytetracycline and carboplatin, MCF-7 representative cell treated with carboplatin with/without different concentrations of oxytetracycline (5% and 10% of IC50). Oxytetracycline, which potentiated the action of carboplatin and/or had notable activity was reported as a single agent. This research demonstrated the synergistic relationship between oxytetracycline and carboplatin in viability assays. Surprisingly, our findings suggest that inhibiting treatment strategies can extend carboplatin’s therapeutic window, potentially allowing for cancer therapy.

Intraocular melanocytic neoplasms are common in dogs. However, the choroidal location of these neoplasms and their infiltration into the optic nerve are unusual. This paper reports a case of primary choroidal melanoma in a 12-year-old male Dachshund. On the first examination, the animal presented left eye blepharospasm, protrusion of the nictitating membrane, conjunctival hyperemia, moderate congestion, hyphema, and intraocular hypertension. Opacity hindered the performance of fundoscopy in the affected eye. The ocular ultrasound examination revealed a cupuliform mass in the choroid. Due to suspected intraocular neoplasia, an exenteration was performed. Histopathological examination revealed primary choroidal melanoma with scleral and optic nerve invasion.

Chemotherapy agents have some undesirable and non-selective cytostatic effects. Considering that kidneys are vulnerable to drug-induced toxicity, this study evaluated renal injury caused by vincristine sulfate (VS) in 12 female dogs diagnosed with transmissible venereal tumor (TVT). The animals were treated with VS (0.025 mg/kg IV) every 7 days for 4 weeks. During treatment, the animals were subjected to clinical examination, blood count, serum measurement of symmetric dimethylarginine (SDMA), blood urea nitrogen (BUN), creatinine, alanine aminotransferase, and alkaline phosphatase. In addition, urinalysis and urinary gamma-glutamyl transferase (GGT) measurements were performed. All parameters were determined three times: before beginning the treatment (T0), after 14 days (T1), and after 28 days (T2). During the study period, there were no changes in serum urea or creatinine levels, urine specific gravity, or persistent proteinuria. Furthermore, urinary GGT measurement did not indicate tubular lesions, and consistent elevation of SDMA was found in only one patient above the reference range. The results showed that weekly therapy with VS as a single agent for 28 days does not induce renal injury in most cases.

Pythiosis is caused by an aquatic fungus-like organism (Pythium insidiosum). It is considered an important public health issue as it can affect both animals and humans. This paper reports a case of gastrointestinal pythiosis in a dog. The patient was hospitalized for four days, during which the animal received supportive and symptomatic treatment. But the applied treatment was unsuccessful and the dog’s clinical condition worsened, culminating in death. Complementary imaging tests such as radiography and ultrasonography, as well as hematological tests, were performed during the hospitalization period. The definitive diagnosis was reached in the postmortem as macroscopic and microscopic characteristics suggested the presence of intestinal granuloma and accentuated multifocal suppurative necrotic enteritis. Additionally, the histological evaluation revealed morphological structures compatible with P. insidiosum. Also, the results of nested PCR performed showed partial amplification (105 bp) of the ITS1 region of the ribosomal gene of P. insidiosum.

Leishmaniases comprise a spectrum of diseases caused by protozoan parasites of the genus Leishmania, with some species of rodents being incriminated as reservoirs. The capybara is the largest extant rodent species in the world and is widely distributed in South America. The occurrence of infection by Leishmania spp. was investigated in capybaras captured in Brazil during 2015–2019 from established populations in five highly anthropic areas of the state of São Paulo and two natural areas of the states of Mato Grosso and Mato Grosso do Sul. A total of 186 individuals were captured and subjected to abdominal skin biopsy. All skin samples were Leishmania kDNA-negative, suggesting that capybaras have no role in the transmission cycles of Leishmania species in the studied areas despite the well-known role of other rodents in the life cycle of Leishmania spp.

The objective of this study was to estimate (co)variances and genetic parameters and to predict genetic trends for weight at 120 (W120), 210 (W210), 365 (W365), and 450 (W450) days of age in Nelore cattle raised in the northern region of Brazil. The database comprised records of 30,387 animals born between 2000 and 2013 in the Brazilian North. Estimates were calculated by the Restricted  Maximum Likelihood (REML) method, in single- and multi-trait analyses in an animal model. Heritability as obtained using single- and multi-trait models for W120 (0.22 and 0.31), W210 (0.20 and 0.34), W365 (0.51 and 0.51), and W450 (0.49 and 0.51) indicated moderate to high magnitudes, with the possibility of genetic selection and incorporation into the herd. Genetic correlations between growth traits were favorable, ranging from 0.78 to 0.96. Genetic trends for W120 and W210 varied largely, from -0.31 to 4.68 and -0.53 to 7.62 kg/year, respectively. Smaller fluctuations were observed in genetic trends for W365 and W450, which ranged from -1.08 to 10.90 and -1.29 to 12.51 kg/year, respectively. Selection for W365 and W450 proved to be the criterion of choice for Nelore herds raised in the region; however, it may compromise adult performance because of higher costs and time for production. A thorough analysis of mattings is recommended to allow the selection of earlier-developing animals.

The COVID-19 cases in Tanjung Jabung Barat Regency, Jambi, have has risen significantly daily. This significant increase in cases illustrates that the people are less than optimal in complying with the health protocols established by the government. This phenomenon concluded that public compliance in efforts to prevent COVID-19 has a vital role in preventing the spread. This study aims to describe the level of compliance towards prevention efforts of COVID-19 in the community. We use a descriptive survey method with probability sampling techniques to obtain the data. The subjects in this study were the community of Tanjung Jabung Barat, Jambi Regency, who were17 years old with a sample size of 400 samples. Collecting data using a questionnaire in a validated form and distributed to the public via social media. The data analysis in this study is the frequency distribution analysis (univariate analysis). The results of this study shown were that 172 respondents (43.0%) had a good level of compliance, 146 respondents (36.5%) had a sufficient level of adherence, and as many as 82 respondents (20.5%) had a good level of compliance to prevent COVID-19 spreads.

This study aims to determine beef types Dark, Firm, and Dry (DFD) and Pale, Soft, and Exudative (PSE) that are sold at the Peunayong Market, Banda Aceh. A total of nine samples of beef from different sellers will be used as extracts and the pH is measured three times every 1 hour for 12 hours to determine the trend of decreasing pH. Organoleptic observations were carried out to determine the visual differences shown by the meat samples. Parameters observed were meat color, meat aroma, meat texture and surface state of the meat. The data obtained from pH measurements and organoleptic tests were analyzed descriptively. Based on the results of pH measurements seen from the decreasing trend of pH in nine samples of beef, seven of them were PSE type beef with a pH value of 5.2 and the other two samples were of good quality meat with a pH value ranging from 5.6 to 5.4. From the results of organoleptic tests for color parameters, four samples were pale, one sample was very pale and the rest were red. All the meat samples tasted normal. Meat texture and surface condition for soft-textured meat has a wet surface, while hard-textured meat has a dry surface.
