In the present paper, we offer a preliminary mathematical model that describes the dynamic process of cell infection with baculovirus at low multiplicity of infection (MOI). The model accounts for the chain of events that follow the infection of insect cells, namely the eclipse period, the budding of viral particles from those cells, their attachment to non-infected cells and the initiation of a new infection cycle. These cycles appear as fluctuations in the viral concentration of actual cell culture media. The potential of the present approach in simulating the in vitro production of biological insecticides is demonstrated. The influence of the shape of the virus-budding function is shown, and parameter sensitivity analysis is carried out. The model provides a quantitative tool for the analysis of this complex dynamic system.

Tooth movement is a complex process involving the vascularization of the tissues, remodeling of the bone cells, and periodontal ligament fibroblasts under the hormonal and neuronal regulation mechanisms in response to mechanical force application. Therefore, it will inevitably impact periodontal tissues. Prolonged treatment can lead to adverse effects on teeth and periodontal tissues, prompting the development of various methods to reduce the length of orthodontic treatment.

Background: poses a considerable global public health challenge. In Egypt, approximately 60% of the inhabitants in the Northern and Eastern areas of the Nile Delta are affected by this parasite, whereas the Southern region experiences a significantly lower infection rate of 6%.
Aim: Construction of an immune phage display Nbs library based on the VHH framework for selecting -specific Nbs for seeking cost-effective, sensitive, and specific diagnostic tools for rapidly detecting mansoni.

From a One Health perspective, dogs and cats have begun to be recognized as important reservoirs for clinically significant multidrug-resistant bacterial pathogens. In this study, we investigated the occurrence and genomic features of ESβL producing Enterobacterales isolated from dogs, in the province of Imbabura, Ecuador. We identified four isolates expressing ESβLs from healthy and diseased animals.

Cell-based meat (CBM) technology is a highly promising alternative to traditional animal agriculture, with considerable advantages in terms of sustainability, animal welfare, and food security. Nonetheless, CBM's successful commercialization is dependent on efficiently dealing with several critical concerns, including ensuring biological, chemical, and nutritional safety as well as navigating the global regulatory framework. To ensure CBM's biological safety, detecting and mitigating any potential hazards introduced during the manufacturing process is crucial.

Para-pneumonic effusion in children is often associated with bacterial infections; however, dual viral infections, including respiratory syncytial virus (RSV) and COVID-19, can also lead to severe respiratory complications, as demonstrated in this case. This case report presents the clinical course of a pediatric patient with both RSV and COVID-19 infections, leading to para-pneumonic effusion. A three-year-old girl with a history of asthma and prior febrile convulsions presented to the Emergency Department with fever, cough, vomiting, and fatigue.
