A viscoelastic-plastic deformation model of hemisphere-like tip growth in Arabidopsis zygotes.

Quant Plant Biol

December 2024

Department of Mechanical Engineering, Faculty of Systems Science and Technology, Akita Prefectural University, Yurihonjo, Japan.

Plant zygote cells exhibit tip growth, producing a hemisphere-like tip. To understand how this hemisphere-like tip shape is formed, we revisited a viscoelastic-plastic deformation model that enabled us to simultaneously evaluate the shape, stress and strain of Arabidopsis () zygote cells undergoing tip growth. Altering the spatial distribution of cell wall extensibility revealed that cosine-type distribution and growth in a normal direction to the surface create a stable hemisphere-like tip shape.

Genetic diversity within a tree and alternative indexes for different evolutionary effects.

Quant Plant Biol

December 2024

Department of Biology, Faculty of Science, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan.

Trees, living for centuries, accumulate somatic mutations in their growing trunks and branches, causing genetic divergence within a single tree. Stem cell lineages in a shoot apical meristem accumulate mutations independently and diverge from each other. In plants, somatic mutations can alter the genetic composition of reproductive organs and gametes, impacting future generations.

Getting it right: suppression and leveraging of noise in robust decision-making.

Quant Plant Biol

November 2024

Department of Forest Genetics and Plant Physiology, The Swedish University of Agricultural Sciences, Umeå Plant Science Center, Umeå, Sweden.

Noise is a ubiquitous feature for all organisms growing in nature. Noise (defined here as stochastic variation) in the availability of nutrients, water and light profoundly impacts their growth and development. Not only is noise present as an external factor but cellular processes themselves are noisy.

Plant growth and development are tightly regulated by cell division, elongation, and differentiation. A visible plant phenotype at the tissue or organ level is coordinated at the cellular level. Among these cellular regulations (cell division, elongation and differentiation), cell division in plants follows the same universal mechanisms across kingdoms of life, and involves conserved cell cycle regulatory proteins (cyclins, cyclin-dependent kinase and cell cycle inhibitors).

Atopic dermatitis is a chronic inflammatory skin disease associated with immune dysregulation, particularly overexpression of T helper 2 cytokines. Cytotoxic T lymphocyte-associated antigen 4 deficiency, a primary immune disorder, can exacerbate atopic dermatitis. Dupilumab, an IL-4 and IL-13 receptor antagonist, has demonstrated efficacy in controlling severe, recalcitrant atopic dermatitis by mitigating T helper 2-driven inflammation.

(), a periodontal pathogen, has been implicated in the impairment of anti-tumor responses in colorectal cancer (CRC). The tumor microenvironment in CRC involves tumor-associated macrophages (TAMs), which are pivotal in modulating tumor-associated immune responses. The polarization of TAMs towards an M2-like phenotype promotes CRC progression by suppressing the immune system.

Diabetic cardiomyopathy (DCM) is a major complication of type 2 diabetes mellitus (T2DM), but its effective prevention and treatment are still limited. We investigated the effects of GYY4137, a slow-releasing hydrogen sulfide donor, and its downstream mediator forkhead box protein O1 (FOXO1) on T2DM-associated DCM. , T2DM mice were induced by a high-fat diet coupled with streptozotocin injection.

Anim Cells Syst (Seoul)

December 2024

School of Systems Biomedical Science, Soongsil University, Seoul, Republic of Korea.

Tissue growth is controlled by various signaling pathways, such as the insulin/IGF-signaling (IIS) pathway. Although IIS activation is regulated by a complex regulatory network, the mechanism underlying miRNA-based regulation of the IIS pathway in wing development remains unclear. In this study, we found that the wing size of adult flies was negatively affected by miR-263b expression.

The anti-tumor effect of the IFNγ/Fas chimera expressed on CT26 tumor cells.

Anim Cells Syst (Seoul)

January 2025

Department of Biochemistry, College of Natural Sciences, Chungnam National University, Daejeon, Korea.

Interferon gamma (IFNγ) is well-known for its ability to stimulate immune cells in response to pathogen infections and cancer. To develop an effective cancer therapeutic vaccine, CT26 colon carcinoma cells were genetically modified to express IFNγ either as a secreted form (sIFNγ) or as a membrane-bound form. For the membrane-bound expression, IFNγ was fused with Fas (mbIFNγ/Fas), incorporating the extracellular cysteine-rich domains, transmembrane, and cytoplasmic domains of Fas.

It is essential in combat sports such as boxing for athletes to perceive the relevant visual information that enables them to anticipate and respond to their opponent's attacking and defensive moves. Here, we used virtual reality (VR), which enables standardization and reproducibility while maintaining perception-action coupling, to assess the influence of a gaze-contingent blur on the visual processes that underpin these boxing behaviours. Eleven elite French boxers were placed in an immersive and adaptive first-person VR environment where they had to avoid by dodging one or two punches, and then counterattack to strike their opponent.

Developing the aquaticity level in healthy adolescents. A randomized control study.

Front Sports Act Living

December 2024

Department of PE and Sports Science, School of Physical Education, Sport Science and Dietetics, University of Thessaly, Volos, Greece.

Unlabelled: Aquaticity is an important parameter of human aquatic performance and behavior and can be objectively assessed by the aquaticity assessment test. Low aquaticity score can unveil a person's high risk in the water while it could dictate the specific characteristics that need to be addressed or developed for improving water competence.

Aim: The aim of the current study was to assess whether human aquaticity can be developed by systematic exercise and which type of training is more effective in improving aquaticity score.

Cannabis inflorescences represent an important source of many high-value bioactive specialized metabolites, among which the family of terpenes or terpenoids that are the largest classes of natural products known. Besides their biological activities either alone or synergistic with other terpenoids and/or cannabinoids, they are responsible for their distinctive flavour. In this study, we exploited the separation power and identification capabilities of comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC-MS) for the profiling of terpenes and terpenoids in cannabis inflorescences.

Proper identification and management of post-kala-azar dermal leishmaniasis (PKDL) and canine leishmaniasis (CanL) cases are among the prerequisites to the effective control of visceral leishmaniasis worldwide. Unlike PKDL, CanL still awaits effective improvement because of its cryptic nature, absence of parasites in lesions or lymph nodes and not complete sensitivity of some diagnostic tools in use. Because of the need for certain skills and equipment, both the liquid direct agglutination test and freeze-dried direct agglutination test (FD-DAT) versions are, in comparison with the indirect immunofluorescence antibody test (IFAT) or enzyme-linked immunosorbent assay (ELISA), practical and feasible diagnostic alternatives.
