Objective: validate method of fixation of dressings on excisional cutaneous wounds of mice. Method: preclinical study. Sample made up of animals of the C57BL/6 strain, which had two excision wounds made in the dorsal region. Different methods and products, widely accepted in clinical practice, for fixing dressings in the animal model were evaluated. The evaluated outcomes were the length of stay of the dressing and the occurrence of adverse events. Results: crepe bandage, microporous tape and self adhesive bandage had a shorter residence time when compared to polyurethane film. This, in turn, varied the time when comparing different marks (E, F, G and H) and number of turns around the animal’s body. With 1 lap, the time varied from <24 to 36 hours. With 2 laps, the marks E and G remained 48 and 96 hours, respectively, and F and H time <24 hours. G-brand film, cut to size 3 cm x 15 cm, giving the mouse body 2 turns, kept the dressing for 96 hours. The skin remained intact, with no adverse event. Conclusion: a dressing fixation model for wounds in mice was created with a product available in Brazil and compatible with the animal’s body structure.

Pancreatic cancer (PC) is one of the most common malignant tumors in the digestive tract worldwide, with increased morbidity and mortality. In recent years, with the development of surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy, and the change of the medical thinking model, remarkable progress has been made in researching comprehensive diagnosis and treatment of PC. However, the present situation of diagnostic and treatment of PC is still unsatisfactory. There is an urgent need for academia to fully integrate the basic research and clinical data from PC to form a research model conducive to clinical translation and promote the proper treatment of PC. This paper summarized the translation progress of mass spectrometry (MS) in the pathogenesis, diagnosis, prognosis, and PC treatment to promote the basic research results of PC into clinical diagnosis and treatment.

Despite the complexity of neurodevelopmental disorders (NDDs), from their genotype to phenotype, in the last few decades substantial progress has been made in understanding their pathophysiology. Recent accumulating evidence shows the relevance of genetic variants in thousand and one (TAO) kinases as major contributors to several NDDs. Although it is well-known that TAO kinases are a highly conserved family of STE20 kinase and play important roles in multiple biological processes, the emerging roles of TAO kinases in neurodevelopment and NDDs have yet to be intensively discussed. In this review article, we summarize the potential roles of the TAO kinases based on structural and biochemical analyses, present the genetic data from clinical investigations, and assess the mechanistic link between the mutations of TAO kinases, neuropathology, and behavioral impairment in NDDs. We then offer potential perspectives from basic research to clinical therapies, which may contribute to fully understanding how TAO kinases are involved in NDDs.

The recent resurgence of interest in the use of intravital microscopy in lung research is a manifestation of extraordinary progress in visual imaging and optical microscopy. This review evaluates the tools and instrumentation available for a number of imaging modalities, with particular attention to recent technological advances, and addresses recent progress in use of optical imaging techniques in basic pulmonary research. 1 Limitations of existing methods and anticipated future developments are also identified. Although there have also been major advances made in the use of magnetic resonance imaging, positron emission tomography, and X-ray and computed tomography to image intact lungs and while these technologies have been instrumental in advancing the diagnosis and treatment of patients, the purpose of this review is to outline developing optical methods that can be evaluated for use in basic research in pulmonary biology.

The structural and functional properties of neurons have intrigued scientists since the pioneering work of Santiago Ramón y Cajal. Since then, emerging cutting-edge technologies, including light and electron microscopy, electrophysiology, biochemistry, optogenetics, and molecular biology, have dramatically increased our understanding of dendritic properties. This advancement was also facilitated by the establishment of different animal model organisms, from flies to mammals. Here we describe the emerging model system of a Caenorhabditis elegans polymodal neuron named PVD, whose dendritic tree follows a stereotypical structure characterized by repeating candelabra-like structural units. In the past decade, progress has been made in understanding PVD's functions, morphogenesis, regeneration, and aging, yet many questions still remain.

A constant demand in engineering design is to couple aesthetics and functionality of design. In this paper, a method is proposed to rapidly update the structural analysis models given the modifications made in the styling/packaging designs, forming a concurrent mechanism for developing the automotive styling and body structure. The seemingly disparate domains are represented by and thus coupled through a pair of wireframes. A joint mapping based on the hard points in packaging and a part mapping encoding local influences between wireframes are established. The deformation transfer from one of the wireframes to the other is solved as an optimization with constraints obtained from the two mappings. Finally, the finite element mesh model is adapted in accordance with the deformed structural wireframe, using a mesh morphing method based on the free-form deformation technique. Numerical results validate the proposed method and demonstrate its effectiveness.

Microglia is one of the major resident immune cells in the central nervous system and is considered to be the key cellular mediator of neuroinflammatory processes. Identification of different Microglial states of activation by morphologic means has been one of the major challenges in the field of neurobiology of diseases. Therefore, microglial biology demands techniques to identify differing stages of microglia in different neuroanatomic locations as well as understanding the role of Microglia in different Neurological diseases. This present study is aimed towards summarizing the literature and for understanding the progress made in different Cytomorphological and Cytochemical techniques of identifying Microglia. This study also review recently used Immunohistochemistry techniques, along with Ultrastructural studies determining different morphological features of resting to activated phagocytic Microglia in a viral induced experimental animal model of neuroinflammation. Results revealed that chronic Microglial activation is considered to be an important component of neuronal dysfunction, injury, and loss (and hence to disease progression). Thus, Microglial research with special emphasis on identification of different activation states of Microglia has gradually become significant.

Animal models serve as powerful tools for investigating the pathobiology of cancer, identifying relevant pathways, and developing novel therapeutic agents. They have facilitated rapid scientific progress in many tumor entities. However, for establishing a powerful animal model of uveal melanoma fundamental challenges remain. To date, no animal model offers specific genetic attributes as well as histologic, immunologic, and metastatic features of uveal melanoma. Syngeneic models with intraocular injection of cutaneous melanoma cells may suit best for investigating immunologic/tumor biology aspects. However, differences between cutaneous and uveal melanoma regarding genetics and metastasis remain problematic. Human xenograft models are widely used for evaluating novel therapeutics but require immunosuppression to allow tumor growth. New approaches aim to establish transgenic mouse models of spontaneous uveal melanoma which recently provided preliminary promising results. Each model provides certain benefits and may render them suitable for answering a respective scientific question. However, all existing models also exhibit relevant limitations which may have led to delayed research progress. Despite refined therapeutic options for the primary ocular tumor, patients’ prognosis has not improved since the 1970s. Basic research needs to further focus on a refinement of a potent animal model which mimics uveal melanoma specific mechanisms of progression and metastasis. This review will summarise and interpret existing animal models of uveal melanoma including recent advances in the field.

For the past few years, the number of structural genomics projects has been growing enormously worldwide. All these projects are supported by substantial financial resources and therefore are able to employ robotics for setting up high-throughput platforms. This paper addresses a simple question: how can basic research laboratories draw profit from the efforts and innovations that have been made to establish high-throughput facilities? To answer this question, the implementations that have been made in the authors' laboratory to improve manual crystallization setup with very limited financial investments are presented. In combination with 96-well microplates, an advanced protocol has been introduced and several simple devices have been designed to speed up different aspects of the manual crystallization setup, from storage of solutions to the setting of drops. These implementations lead to the reduction of costs in terms of time and money without any loss of quality. In addition, the crystallization throughput in the manual setup has been significantly increased.
