Pentatrichomonas hominis, a flagellated parasitic protozoan, predominantly infects the mammalian digestive tract, often causing symptoms such as abdominal pain and diarrhea. However, studies investigating its pathogenicity are limited, and the mechanisms underlying P. hominis-induced diarrhea remain unclear. Establishing an in vitro cell model for P. hominis infection is imperative. This study investigated the interaction between P. hominis and IPEC-J2 cells and its impact on parasite growth, adhesion, morphology, and cell viability. Co-cultivation of P. hominis with IPEC-J2 cells resulted in exponential growth of the parasite, with peak densities reaching approximately 4.8 × 105 cells/mL and 1.2 × 106 cells/mL at 48 h for initial inoculation concentrations of 104 cells/mL and 105 cells/mL, respectively. The adhesion rate of P. hominis to IPEC-J2 cells reached a maximum of 93.82% and 86.57% at 24 h for initial inoculation concentrations of 104 cells/mL and 105 cells/mL, respectively. Morphological changes in IPEC-J2 cells co-cultivated with P. hominis were observed, manifesting as elongated and irregular shapes. The viability of IPEC-J2 cells exhibited a decreasing trend with increasing P. hominis concentration and co-cultivation time. Additionally, the mRNA expression levels of IL-6, IL-8, and TNF-α were upregulated, whereas those of CAT and CuZn-SOD were downregulated. These findings provide quantitative evidence that P. hominis can promote its growth by adhering to IPEC-J2 cells, inducing morphological changes, reducing cell viability, and triggering inflammatory responses. Further in vivo studies are warranted to confirm these results and enhance our understanding of P. hominis infection.

Background: Bromhidrosis, characterized by foul‐smelling sweat, is a prevalent condition that significantly affects patients' social and psychological well‐being. Methods: This review presents novel treatment approaches and discusses the pros and cons of various treatment options for axillary bromhidrosis. Results: Extensive research has explored numerous treatment modalities for bromhidrosis. This article systematically reviews both surgical and nonsurgical interventions utilized in clinical practice. Conclusion: By synthesizing available evidence, this review aims to offer evidence‐based recommendations for effectively managing bromhidrosis, considering factors such as treatment efficacy, safety profiles, patient preferences, and clinical outcomes.

The problem of data heterogeneity is one of the main challenges facing federated learning (FL). Non-IID data usually introduce bias in the training process of FL models, which can impact the accuracy and convergence speed of the models. To this end, we propose a personalized federated learning (PFL) algorithm with adaptive dynamic adjustment of the gradient clipping boundaries and the idea of freezing to reduce the influence of non-IID data on the model, called PerFreezeClip. PerFreezeClip is a design decision regarding parameter architecture, comparing the private and federated models. PerFreezeClip facilitates the training of each device based on an adaptive clipping gradient during training, with more rational updates and more stable gradients. The results based on the CIFAR-10 and CIFAR-100 datasets show that the proposed PerFreezeClip algorithm provides higher test accuracy after controlling the gradient: a maximum of a 50% enhancement compared to typical federated learning (non-personalized) algorithms.

Green leafy vegetables are an essential component of Chinese leafy vegetables. Due to their crisp stems and tender leaves, orderly harvester generally causes significant mechanical clamping damage. The physical and mechanical properties of green leafy vegetables are one of the important basis to design the orderly harvester. At the same time, they provide important parameters for the simulation and optimization of harvester. So, this paper measured the physical characteristic parameters of roots and stems of green leafy vegetables. Then, based on the TMS-Pro texture analyzer, the elasticity modulus of the roots and stems of green leafy vegetables were measured. The static friction coefficient, dynamic friction coefficient, and restitution coefficient of green leafy vegetables root-root, stem-stem, root-steel, and stem-steel were measured separately using a combination method of inclined plane and high-speed photography. Uniaxial compression creep experiments were carried out on whole and single leaf of green leafy vegetables using the TA.XT plus C universal testing machine. The constitutive equation of the four-element Burgers model was used to fit the deformation curve of the sample with time during the constant-pressure loading stage. The fitting determination coefficients R2 were all higher than 0.996, which verified the reasonable validity of the selected model. The above experimental results provide a parameter basis and theoretical support for the design and discrete element simulation optimization of orderly harvester critical components of green leafy vegetables.
