Published: January 2025

An abscess is a localized pocket of pus that forms in tissues, organs, or spaces within the body as a natural defense mechanism against infection or foreign substances. Dorsal cervical abscesses are a common occurrence in cattle, often sequel to bacterial infections or traumatic injuries. This case study presents the successful surgical management of a large dorsal cervical abscess in a five-year-old white Fulani bull. The bull presented with a large, fluctuant swelling on the dorsal aspect of the neck, which was causing significant discomfort and restricting its Appetite for feed. The abscess was surgically lanced on the dependent part and the entire contented was drained and debrided, postoperative management was carried out with penicillin-streptomycin antibiotic and charmil® plus ointment leading to a successful resolution of the infection and a complete recovery of the bull after four weeks post-surgery. This case highlights the importance of effective surgical intervention in the management of large dorsal cervical abscesses in cattle.
Molecular study and phylogenetic analysis of hemotropic Mycoplasma in Baghdad province, Iraq
Authors: Saeed Dunya , Badawi Naseir
Published: January 2025

Background:
Hemotrophic Mycoplasmas (HMs) are uncultivable, pleomorphic, very small epicellular, and like another Mycoplasma species lacking a cell wall. These pathogens damage and alter the erythrocytes by invading or parasitizing their surface, which can lead to persistent infections and complications. The most common hemotrophic Mycoplasmas species in dogs are Candidatus Mycoplasmas haematoparvum (CMhp), and Mycoplasma haemocanis (Mhc).

Aim:
The study aimed to detect infectious rates of hemotrophic Mycoplasma infections in dogs by molecular assay from Baghdad province for the first time.

Methods:
The study included 155 dogs consisting vary breeds, ages and both sexes from October 2023 to March 2024. The target gene for identified HMs in dogs was the 16s rRNA gene, where used two primers to amplify a fragment of approximately 618 bp of the target gene.

Results:
The PCR results indicated 618 bp band of positive 16s rRNA gene of HMs. Six out of 155 dogs tested were positive by PCR, producing a 4% infection rate of HMs in dogs in Baghdad/Iraq (2% of each CMhp and uncultured Mycoplasma spp.), which had 100% matching with Mhc based on the 16S rRNA sequences. The highest infection rates were reported non-significantly in January in dogs older than 1 year, males, and significantly in the Malinois dogs. The main hematological values exhibited significant changes in the MCHC, RDW, and PDWS; also, normocytic normochromic and microcytic normochromic anemia were observed in two dogs infected with hemotropic mycoplasmosis. The phylogenetic analysis revealed that sequence alignment on the NCBI-BLAST site had high identity with M. hacmocanis recorded by NCBI uncultured Mycoplasma spp. and candidatus Mycoplasma hemtoparvum. The relationship between geographical regions and uncultured Mycoplasma spp. and CMhp of the present study in the phylogenic trees revealed that sequences were grouped in the same branch of the several countries in the phylogenic tree, especially neighboring countries (Iran and Turkey).

Conclusion:
This study is the first molecularly and phylogenetically detected of hemotropic Mycoplasma in Baghdad/Iraq. The results of phylogenetic analysis indicated that there was no specific substitution of sequences or genetic diversity of the hemotropic Mycoplasma in dogs from Iraq with other countries.

Authors: Shaldoum Fayez , Alsharari Meshari , Alrashidi Barakat
Published: January 2025

Background:
Wild Birds have hazards of carrying parasites that are possibly transmitted to man.

Aim:
The aim of this work is to recover parasites from the possibly infected wild birds.

Methods:
Three wild birds of each type of quail, doves and pigeon were caught at Al-Jouf region. They were sacrificed and contents of their gut were studied using microscopy.

Results:
Two different species of Cestodes (tapeworms) of order Cyclophyllidea were recovered from wild quail and dove. Only one Mesocestoides sp. worm has been recovered from one wild quail. Mesocestoididae is a family of Cestoda in the order Cyclophyllidea. Members of this family are gut parasites of small mammals and occasionally birds. Cestodes in the genus Mesocestoides are common in carnivores but only very rarely infect humans. Ten Raillietina sp. worms have been recovered from a wild dove. The majority of Raillietina spp. infect avian definitive hosts. It may cause rare accidental innocuous infections in humans.

Conclusion:
There is much to be learned about possible transmission of these cestodes from birds to humans, and further research in this area could have important implications for both human and animal health. Projects must be adopted for making survey of what Parasites may wild animals carry to raise the level of health, environmental and economic awareness of the community.

Published: January 2025

Myostatin (MSTN) is an essential gene that regulates muscle growth and development in livestock animals, influencing meat production and carcass quality. This review looks at myostatin genetic diversity in a variety of animals, including cattle, sheep, goats, and poultry, focusing on correlations between particular mutations and phenotypic parameters like muscle mass and growth rate. Mutations in the MSTN gene have been linked to desirable features such as greater body weight and higher meat quality, making it an ideal candidate for genetic selection in breeding programs. Animals carrying this mutation frequently transform feed into muscle more efficiently, resulting in faster growth with less feed input. This is advantageous for growers seeking to cut feed costs while raising yields. MSTN-mutated animals convert feed into muscle more efficiently, lowering production costs over time and making them more appealing for commercial breeding operations. Advances in molecular genetics, especially CRISPR-Cas9 technology, have made it possible to precisely manipulate the myostatin gene, allowing for the development of calves with enhanced muscle mass. This article also examines the effects of myostatin variation on meat production efficiency, as well as current issues in animal genetics. This research synthesis emphasizes the significance of myostatin in cattle breeding, specifically its potential as a genetic marker to improve production and meat quality in commercial farming.

Authors: Jamarun Novirman , Ikhlas Zaitul , Zain Mardiati , Negara Windu , Pazla Roni , Yanti Gusri
Published: January 2025

Background:
Alternative feeds for ruminants that can be explored are sugarcane tops as a source of crude fibre and tithonia as a source of protein. Long droughts and direct use of these components may not meet nutritional standards. Processing technologies such as wafer production, using tapioca starch as an adhesive, can improve feed durability, storage and nutritional consistency. The addition of tapioca starch in ruminants feed should be considered, as its high starch content may affect overall feed digestibility.

Aim:
This research aims to assess at knowing the impact of the use of tapioca starch as an adhesive on complete feed wafers based on fermented sugarcane tops and tithonia to produce sturdy physical quality of wafers and increase in vitro digestibility of nutrients.

Methods:
The experiment used a group randomised design with 4 treatments, consisting of 5% tapioca starch in the ration (T1), 10% tapioca starch in the ration (T2), 15% tapioca starch in the ration (T3), 20% tapioca starch in the ration (T4), and 5 groups as replicates. The parameters included physical properties of wafers (aroma, texture, color, water binding capacity, and density), in vitro digestibility of nutrients, VFA production, NH3, pH, methane gas production, and total gas production.

Results:
The results indicated that the use of tapioca starch had a non-significant effect (P>0.05) on colour, and significant effect (P<0.05) on aroma and texture. Digestibility of nutrients, rumen fluid characteristics, and total gas and methane gas production were significant (P<0.05). Has a firm, dense texture (not easily broken), a distinctive aroma of wafers, and a stable rumen pH of 6.96 in the T2 treatment made effective rumen conditions indicated by dry matter digestibility of 62.41%, organic matter digestibility of 62.52%, and protein digestibility of 64.40%.

Conclusion:
The research concludes that in the T2 treatment, the addition of 10% tapioca flour as an adhesive and energy source in a complete feed wafer ration based on fermented sugarcane tops and tithonia being the best treatment for physical quality, and nutrient digestibility.

Authors: Ishizaka Mio , Hsu Huai , Miyagawa Yuichi , Takemura Naoyuki
Published: January 2025

Background:
Omecamtiv mecarbil (OM), a selective cardiac myosin activator, is gaining attention as a potential heart failure treatment because it can enhance cardiac contractility without adverse effects. Concerns were raised about arrhythmias with conventional heart failure treatments in cats. Despite OM’s promise in veterinary medicine, no studies have confirmed its efficacy in cats.

Aim:
This study aimed to investigate the pharmacodynamics of OM in cats.

Methods:
Five clinically healthy cats were used. OM’s efficacy was examined in three doses: 0.1, 0.25, and 1.0 mg/kg. To minimize the effect on heart rates, the cats were under general anesthesia, and baseline measurements were taken after the heart rate and blood pressure had stabilized. OM was administered as a single intravenous injection. Echocardiography was performed 15, 30, 60, 90, and 120 min after administration. Heart rate and blood pressure were measured before each echocardiographic examination.

Results:
The heart rates decreased at all doses; significant reductions were seen at 0.25 and 1.0 mg/kg. All doses enhanced cardiac contractility, showing a dose-dependent effect. Blood pressure remained unchanged.

Conclusion:
OM enhances cardiac contractility in cats, with 0.25 mg/kg being the optimal dose.
Enhanced inhibitory effects of GABA on renal and hepatic function, molecular profiles, and histological changes in male albino mice
Authors: Ajeel Mohammed , Robaiee Israa
Published: January 2025

Background:
The gamma-aminobutyric acid GABA receptors are considered the main inhibitory neurotransmitter receptors in mammalian brain and they have been proved to be existing in non-neuronal cells.

Aim:
Lorazepam which is one of the benzodiazepines, drugs known for their effect of GABA receptors, has been used in this study as an enhancer to determine the impact of GABA activity enhancement on renal and liver functions, molecular and histological characteristics in male albino mice.

Methods:
Male albino mice were divided in to 3 groups (each has 7 animals) each group was treated with a different dose of lorazepam and 9 animals served as a control group. The molecular parameters included the usage of raped -PCR to detect any universal variations. The histological changes were detected using hematoxylin and eosin histopathological examination. Liver and kidney function test were utilized to detect any functional changes.

Results:
The results of the functional parameters (serum urea, creatinine, glutamate-oxaloacetic transaminase (GOT), glutamate-pyruvic transaminase (GPT), gamma glutamyl enzyme (GGT)) and histopathological examination demonstrated that there was a significant change in treated groups compared to the control group. As for the molecular study, seven primers out of ten gave a single and polymorphic bands using random amplification of polymorphic DNA (RAPD) technique. The results revealed great changes in RAPD profiles of treated groups as normal bands lost and new bands appeared in comparison with the control group. The RAPD profiles of the treated and control samples gave 432 bands, 109 as control bands, 167 (loss of normal bands and appearance of new bands) as polymorphic bands and other 156 as a homomorphic band.

Conclusion:
The marked changes in various biochemical, histopathological and RAPD-PCR profiles indicate that lorazepam-mediated GABA modulation brings about widespread alterations in peripheral organ systems. Taken together, these data suggest caution in the use of lorazepam clinically and potentially represents an unmet need for safer therapeutic alternatives or strategies to limit benzodiazepine-induced organ toxicity.

Published: January 2025

En contraste con los métodos convencionales de producción, surge la agricultura biogénica o generadora de vida como una alternativa para alcanzar bienestar, prosperidad y libertad. Un ejemplo de esta práctica es el uso de Azolla en simbiosis con la cianobacteria Anabaena azollae, capaz de fijar nitrógeno atmosférico y convertirlo en formas asimilables por las plantas, constituyéndose así en una fuente importante de nitrógeno para los cultivos de la agricultura familiar campesina. Con el objetivo de evaluar el efecto del nitrógeno bien expresado proporcionado por Azolla en el cultivo de maíz INIAP-182 “Almendral”, se llevó a cabo un experimento en la parroquia San Pedro de la Bendita, cantón Catamayo, utilizando un diseño experimental de bloques al azar con tres réplicas y cinco tratamientos: biomasa de Azolla, aplicación foliar de NitrAgua, riego con NitrAgua, fertilizante convencional (urea) y un grupo control (testigo). Los mejores resultados se obtuvieron con la aplicación de nitrógeno bien expresado a partir de biomasa de Azolla filiculoides, logrando una altura de planta de 162,4 cm, un diámetro de tallo de 4,7 cm, 15 hojas por planta, mazorcas de 22,2 cm de longitud, 599 granos por mazorca y un rendimiento de 15,53 t/ha. Azolla filiculoides se presenta como una alternativa viable y económica como biofertilizante en el cultivo de Zea mays L., ya que contribuye a mejorar las propiedades fisicoquímicas del suelo debido a su alto contenido de nitrógeno disponible y su rápida descomposición.

Los bosques secos de Ecuador se caracterizan por poseer alta biodiversidad y endemismo, y estar constantemente amenazados. El objetivo de este estudio fue determinar la densidad básica de la madera de 22 especies forestales de bosque seco al sur de Ecuador. Se utilizaron muestras obtenidas mediante un barreno de Pressler, se extrajeron 192 núcleos de madera de 22 especies forestales. Se midió la longitud en verde de cada núcleo de madera, se determinó el diámetro del barreno (0,515 cm), y se calculó el volumen en verde. Las muestras fueron secadas en horno a 105 °C durante cuatro días, y posteriormente pesadas para calcular el contenido de humedad y la densidad básica de la madera. Se registró la altura, ediámetro (DAP) y grosor de la corteza de cada individuo. De las 22 especies estudiadas, 46 % son maderas pesadas, 33 % semipesadas, y 21 % livianas. Las especies con mayor densidad (≥ 0,8 g/cm3) fueron Handroanthus chrysanthus, Terminalia valverdeae, Morisonia scabrida, Morisonia flexuosa y Fulcaldea laurifolia. Las especies con menor densidad (≤ 0,3 g/cm3) fueron Ceiba trischistandra, Cochlospermum vitifolium y Erythrina velutina. No se encontraron diferencias significativas en los 3 rasgos comparados a 600 y 1200 m s.n.m para Erythrina velutina y Eriotheca ruizii. Se detectó una fuerte correlación entre el contenido de humedad y las maderas livianas, mientras que el grosor de la corteza tuvo una baja correlación. Los resultados obtenidos ofrecen una base para futuros estudios ecológicos y estrategias de manejo sostenible en los bosques secos de Ecuador.

Introduction: We aimed to investigate the effect of video-animated information given before flexible cystoscopy under local anesthesia on the anxiety of male patients.
Methods: Before cystoscopy, patients were divided into two groups with 1:1 standard randomization. While one group was given written and verbal information, the other group was additionally given video-animated information. The patients' anxiety levels before the procedure and their hemodynamic parameters during the procedure were compared between the groups. In addition, pain, satisfaction, and willingness to repeat the procedure were compared between the groups.
Results: State-Trait Anxiety Inventory-Sate (STAI-S) levels were found to be statistically significantly lower in the group given video animation information before cystoscopy (p<0.01). It was observed that video information had a positive effect on systolic blood pressure, diastolic blood pressure, and heart rate, and the values were lower than in the comparator group (p <0.01). While there was no statistically significant difference between the two groups in visual analog scale (VAS) pain scores (p=0.24), VAS satisfaction and VAS willingness to repeat the procedure scores were found to be statistically significantly different (p<0.01). It was observed that video-animated information made a positive contribution to satisfaction and willingness to repeat the procedure.
Conclusions: Video-animated information given before a flexible cystoscopy procedure performed on male patients under local anesthesia has positive effects on the patients' anxiety. In addition, it contributes positively to the patient's satisfaction and desire to repeat the procedure. Video-animated information may be routinely used in addition to verbal and written information before the csytoscopy.

A relevância assumida pela temática do acesso à justiça no Brasil, na perspectiva da administração pública gerencial, enfatiza a ideia da prestação jurisdicional como serviço público, devendo atender os princípios constitucionais que regem a Administração Pública. Neste artigo, objetivou-se analisar efeitos da implantação de cargos de Juiz de Direito Auxiliar (JDA) no Tribunal de Justiça do Estado de Mato Grosso (TJMT) como forma de garantir o acesso à justiça por meio de uma prestação jurisdicional eficiente e eficaz. Metodologicamente, realizou-se uma pesquisa descritiva com pesquisa documental e estudo de campo. Como técnica de coleta de dados primários, utilizou-se o painel de especialistas com 12 advogados, presidentes de subseções da OAB/MT, considerados stakeholders relevantes. Os resultados demonstram que a criação dos cargos de JDA teria impacto positivo sobre o lotacionograma de magistrados do TJMT. Ademais, os advogados percebem que a prestação jurisdicional é morosa, sendo que a criação dos cargos de JDA teria impacto positivo sobre a eficiência e a efetividade do serviço jurisdicional no Estado. Conclui-se que a criação dos cargos de JDA impactaria positivamente na eficiência e eficácia da prestação jurisdicional, melhorando a qualidade do acesso à justiça no estado.

Reflexões sobre o armário: tramas, resistências e (in)visibilidades
Authors: Silva Robson Aparecido da Costa , Mesquita Marcos Ribeiro
Published: January 2025

O presente artigo objetiva trazer à tona um debate introdutório em relação às questões político-acadêmicas que permeiam as discussões relativas ao armário entre pesquisadores. Neste estudo, o armário é compreendido enquanto um mecanismo de regularidade de vidas LGBTQIA+, um dispositivo epistemológico que forja constantes fluxos e tramas de privilégios, visibilidade e hegemonia de valores às pessoas cis e heterossexuais. Uma estrutura regulatória de nível individual e coletivo, não apenas das dissidências de gêneros e das sexualidades, que define modos de sociabilidade público-privado, ancoradas no binarismo homo/hétero e na heteronormatividade compulsória; além de produzir regimes históricos de (in)visibilidades que vão adquirindo novas configurações de um contexto para outro e forjando sistemas micro e macropolíticos cujas diretrizes podem mudar entre pessoas que nele vivem e resistem às opressões, violências e atos discriminatórios. O estudo traz enquanto norte metodológico, a revisão bibliográfica da literatura acerca do tema, tendo como base de análise diferentes marcadores sociais da diferença para se refletir sobre o armário. Como principais reflexões podemos afirmar que muitos estudiosos vislumbram o armário enquanto racialmente não-marcado, refletido apenas pelo olhar do gênero e da orientação afetivo-sexual; que esse dispositivo não produz apenas opressão e sofrimentos, uma vez que, o armário também se faz trincheira, abrigo, para muitas/os que nele habitam, se resguardam ou se movimentam entre o entrar e sair, vice-versa. Por fim, cumpre dizer, que ele é um conceito guarda-chuva, capaz de abarcar e/ou aglutinar uma multiplicidade de experiências de vida, de modos distintos, entre diferentes pessoas que nele vivem, um mecanismo capaz de regular o controle de vidas, inclusive LGBTQIA+, mesmo depois de terem se assumido, e construir para elas diretrizes conectadas a trajetória de vida de cada qual sobre as sexualidades.

Heat-not-burn tobacco (HnBT): Isu Pengganti Produk Rokok dan Dampak Kesehatannya
Authors: Agustiawan Agustiawan
Published: January 2025

Adanya risiko kesehatan merokok menyebabkan perusahaan mengembangkan dan mengiklankan produk nikotin alternatif, seperti e-cigarettes dan “heat-not-burn” (HnB) tanpa membakar tembakau. United States’ Federal Drug Administration (US FDA) menyetujui peredaran produk komersil I Quit Ordinary Smoking (IQOS) di Amerika Serikat. Produk tembakau HnB memanaskan tembakau (hingga 350°C) untuk menghasilkan aerosol nikotin yang dihirup tanpa membakarnya pada suhu yang jauh lebih tinggi (800°C). Laporan menunjukkan 37% pengguna HnB mengalami setidaknya satu gejala, yang paling umum adalah sakit tenggorokan (25,1%) diikuti oleh rasa tidak nyaman pada mata (22,3%). Keyakinan produk tembakau HnB sebagai alternatif untuk mereduksi dampak rokok konvensional tidak sepenuhnya benar. Tembakau HnB tetap dapat memberikan dampak buruk terhadap kesehatan.
