A fast-modeling framework for personalized human body models based on a single image.

Finite element human body models (HBMs) are the primary method for predicting human biological responses in vehicle collisions, especially personalized HBMs that allow accounting for diverse populations. Yet, creating personalized HBMs from a single image is a challenging task. This study addresses this challenge by providing a framework for HBM personalization, starting from a single image used to estimate the subject's skin point cloud, the skeletal point cloud, and the relative positions of the skeletons.

Anlotinib treatment for rapidly progressing pediatric embryonal rhabdomyosarcoma in the maxillary gingiva: a case report.

Background: Embryonal rhabdomyosarcoma (ERMS) is a highly aggressive form of soft-tissue sarcoma that predominantly affects children. Due to limited benefits and resistance to therapy, there is an unmet need to explore alternative therapeutic strategies.

Case Presentation: In this report, we present a rare case of pediatric ERMS located on the right side of the maxillary gingiva.

FeO Nanoparticles That Modulate the Polarisation of Tumor-Associated Macrophages Synergize with Photothermal Therapy and Immunotherapy (PD-1/PD-L1 Inhibitors) to Enhance Anti-Tumor Therapy.

Introduction: Traditional surgical resection, radiotherapy, and chemotherapy have been the treatment options for patients with head and neck squamous cell carcinoma (HNSCC) over the past few decades. Nevertheless, the five-year survival rate for patients has remained essentially unchanged, and research into treatments has been relatively stagnant. The combined application of photothermal therapy (PTT) and immunotherapy for treating HNSCC has considerable potential.

Stabilization of EREG via STT3B-mediated N-glycosylation is critical for PDL1 upregulation and immune evasion in head and neck squamous cell carcinoma.

Dysregulated Epiregulin (EREG) can activate epidermal growth factor receptor (EGFR) and promote tumor progression in head and neck squamous cell carcinoma (HNSCC). However, the mechanisms underlying EREG dysregulation remain largely unknown. Here, we showed that dysregulated EREG was highly associated with enhanced PDL1 in HNSCC tissues.

IDENTIFIABLE BOUNDED COMPONENT ANALYSIS VIA MINIMUM VOLUME ENCLOSING PARALLELOTOPE.

In this paper, we revisit bounded component analysis (BCA) and formulate it as a geometric problem of finding the minimum volume enclosing parallelotope (MVEP) of a set of data points in the Euclidean space. A parallelotope is an affine transformation of the standard box, also known as the -norm ball. An immediate benefit of the novel formulation is that the bounds on the supports of the latent components can be arbitrary, unlike most existing BCA works that assume the bounds are symmetric around zero.

A data-mining study on the prediction of head injury in traffic accidents among vulnerable road users with varying body sizes and head anatomical characteristics.

Body sizes and head anatomical characteristics play the major role in the head injuries sustained by vulnerable road users (VRU) in traffic accidents. In this study, in order to study the influence mechanism of body sizes and head anatomical characteristics on head injury, we used age, gender, height, and Body Mass Index (BMI) as characteristic parameters to develop the personalized human body multi-rigid body (MB) models and head finite element (FE) models. Next, using simulation calculations, we developed the VRU head injury dataset based on the personalized models.

A pilot study of camrelizumab with docetaxel and cisplatin for the first line treatment in recurrent/metastatic oral squamous cell carcinoma.

Pembrolizumab with cisplatin and 5-fluorouracil showed survival benefit but relatively high occurrence of treatment-related adverse events (TRAEs) for recurrent/metastatic oral squamous cell carcinoma (R/M OSCC). A more tolerable regime is needed. This trial enrolled 20 R/M OSCC patients with previously untreated and PD-L1 positive.

A fast methodology for generating skeletal FEM with detailed human geometric features based on CPD and RBF algorithms.

Due to the significant effects of the human anatomical characteristics on the injury mechanism of passenger in traffic accidents, it is necessary to develop human body FEM (Finite Element Model) with detailed anatomical characteristics. However, traditional development of a human body FEM is an extremely complicated process. In particular, the meshing of human body is a huge and time-consuming project.

A functional study of zinc-titanium coatings and exploration of the intrinsic correlation between angiogenesis and osteogenesis.

With the development of implant applications, osseointegration has become a criterion for implant success. A good blood supply is essential for successful osseointegration. To improve the pro-angiogenic ability of the implants, in this experiment we introduced zinc into the titanium coating.

Inhibition of Inflammatory Response and Promotion of Osteogenic Activity of Zinc-Doped Micro-Arc Titanium Oxide Coatings.

An early and sustained immune response can lead to chronic inflammation after the implant is placed in the body. The implantable materials with immunomodulatory effects can reduce the body's immune response and promote the formation of ideal osseointegration between the implants and bone tissue. In this study, zinc-coated titanium micro-arc oxide coating was prepared on titanium surface by micro-arc oxidation.

A novel intronic circular RNA, circGNG7, inhibits head and neck squamous cell carcinoma progression by blocking the phosphorylation of heat shock protein 27 at Ser78 and Ser82.

Background: There is increasing evidence that circular RNAs (circRNAs) play a significant role in pathological processes including tumorigenesis. In contrast to exonic circRNAs, which are the most frequently reported circRNAs in cancer so far, the studies of intronic circRNAs have been greatly lagged behind. Here, we aimed to investigate the regulatory role of intronic circRNAs in head and neck squamous cell carcinoma (HNSCC).

EREG-driven oncogenesis of Head and Neck Squamous Cell Carcinoma exhibits higher sensitivity to Erlotinib therapy.

The oncogenesis of head and neck squamous cell carcinoma (HNSCC) is believed to result from oncogene activation and tumor suppressor inactivation. Here, we identified a new oncogenic role for the EREG gene in HNSCC. The TCGA database and immunohistochemistry assay were used to analyze expression of EREG in HNSCC tissues.

Proximal-type epithelioid sarcoma in the maxillary sinus: an unusual presentation.

Epithelioid sarcoma (ES) is a rare histological type of soft tissue sarcoma presenting as a subcutaneous or deep dermal mass in the distal extremities of young adults. Recently, a more aggressive, so called 'proximal-type' ES has been described. The literature is limited on the clinical features and management of ES originating in the head and neck area.

MOF-derived novel porous FeO@C nanocomposites as smart nanomedical platforms for combined cancer therapy: magnetic-triggered synergistic hyperthermia and chemotherapy.

Multifunctional nanomedical platforms have broad prospects in imaging-guided combination therapy in cancer precision medicine. In this work, metal-organic framework (MOF)-derived novel porous Fe3O4@C nanocomposites were developed as an intelligent cancer nanomedical platform for combined cancer therapy with MRI-guided magnetic-triggered hyperthermia and chemotherapy functions. The magnetic behavior, porous character and good surface modification endowed this smart nanoplatform with favorable biocompatibility, high-efficiency MRI imaging, magnetic-triggered on-demand DOX release function, and synergistic therapy of magnetic hyperthermia and chemotherapy, which proposed an all-in-one platform for cancer therapy.

TLR4 activation leads to anti-EGFR therapy resistance in head and neck squamous cell carcinoma.

Epidermal growth factor receptor (EGFR) is highly expressed in head and neck squamous cell carcinoma (HNSCC) and related to cancer progression. The resistance to anti-EGFR therapy remains a major clinical problem in HNSCC. In this study, we found that TOLL-like receptor 4 (TLR4) was highly expressed in 50% of EGFR overexpressed HNSCC biopsies, which correlated to worse prognosis in patients.

Validation of Gene Profiles for Analysis of Regional Lymphatic Metastases in Head and Neck Squamous Cell Carcinoma.

The progress of Head and Neck Squamous Cell Carcinoma (HNSCC) is dependent on both cancer stem cells (CSCs) and immune suppression. This study was designed to evaluate the distribution of CSCs and the characteristic immune suppression status in HNSCC primary tumors and lymph nodes. A total of 303 lymph nodes from 25 patients, as well as tumor and adjacent normal tissue samples, were evaluated by a quantitative PCR assay of the markers of CSCs and the characteristic immune suppression.

A novel IFNα-induced long noncoding RNA negatively regulates immunosuppression by interrupting H3K27 acetylation in head and neck squamous cell carcinoma.

Background: Interferon alpha (IFNα) is a well-established regulator of immunosuppression in head and neck squamous cell carcinoma (HNSCC), while the role of long noncoding RNAs (lncRNAs) in immunosuppression remains largely unknown.

Methods: Differentially expressed lncRNAs were screened under IFNα stimulation using lncRNA sequencing. The role and mechanism of lncRNA in immunosuppression were investigated in HNSCC in vitro and in vivo.

Enhanced corrosion resistance and bioactivity of Mg alloy modified by Zn-doped nanowhisker hydroxyapatite coatings.

In this work, Zn is doped into a hydroxyapatite coating on the surface of ZK60 magnesium alloys using a one-pot hydrothermal method to obtain a corrosion-resistant implant with abilities of osteogenic differentiation and bacterial inhibition. With the addition of Zn, the morphology changes with a nanowhisker structure appearing on the coating. Electrochemical measurements show that the nanowhisker hydroxyapatite coating provides a high corrosion resistance.

Altered expression of TIM-3, LAG-3, IDO, PD-L1, and CTLA-4 during nimotuzumab therapy correlates with responses and prognosis of oral squamous cell carcinoma patients.

Background: Since the inhibitory immune checkpoint receptors have been described to benefit the OSCC patients clinically, it is unknown that whether their expression in tumor immune microenvironment (TME) can determine the clinical outcome in response to nimotuzumab therapy.

Methods: We examined the expression patterns of immune checkpoint receptors (including TIM-3, LAG-3, PD-L1, and CTLA-4) and an immunoregulatory enzyme called IDO in 36 OSCC patients during nimotuzumab therapy by immunohistochemistry. Then, we divided the recruited patients into clinical responders and non-responders according to computed tomography (CT) scan and analyzed the relationship between the immunological parameters and clinical outcome.

Blocking autophagy flux promotes interferon-alpha-mediated apoptosis in head and neck squamous cell carcinoma.

Despite multiple antitumor activities, interferon-alpha (IFNα) therapy alone is less effective in solid tumors. Autophagy has been reported to play a key role in tumor chemoresistance. Therefore, it is meaningful to explore whether autophagy can be activated by IFNα in head and neck squamous cell carcinoma (HNSCC) and serve as a potential target to improve efficacy of IFNα therapy.

Long non-coding RNA ANRIL promotes tumorgenesis through regulation of FGFR1 expression by sponging miR-125a-3p in head and neck squamous cell carcinoma.

ANRIL (CDKN2B antisense RNA 1, CDKN2B-AS1) is involved in the progression of various cancers. However, its role in head and neck squamous cell carcinoma (HNSCC) remains unclear. In this study, we found that ANRIL expression was upregulated in HNSCC and correlated with tumor progression.

Interferon-alpha promotes immunosuppression through IFNAR1/STAT1 signalling in head and neck squamous cell carcinoma.

Background: An immunosuppressive microenvironment is critical for cancer initiation and progression. Whether interferon alpha (IFNα) can suppress immune and cancer cells and its involved mechanism still remain largely elusive.

Methods: We examine the expression of interferon alpha/beta receptor-1 (IFNAR1), CD8, CD56 and programmed death ligand 1 (PDL1) in head and neck squamous cell carcinomas (HNSCC).
