Objective: Tumour-associated macrophages (TAMs) are crucial in the progression and treatment response of oral squamous cell carcinoma (OSCC). TAMs infiltrate OSCC, adopting an M2-like phenotype that promotes tumour growth, metastasis and immune suppression. The current narrative review explored the roles of TAMs in OSCC, focusing on their impact on the tumour microenvironment, invasion, metastasis, angiogenesis, immunosuppression and potential therapeutic targeting.

The past decade witnessed a surge in discoveries where biological systems, such as bacteria or living cells, inherently portray active polar or nematic behavior: they prefer to align with each other and form local order during migration. Although the underlying mechanisms remain unclear, utilizing their physical properties to achieve controllable cell-layer transport will be of fundamental importance. In this study, the ratchet effect is harnessed to control the collective motion of neural progenitor cells (NPCs) in vitro.

Genet Med

January 2025

Newborn Screening Ontario, Children's Hospital of Eastern Ontario, Ottawa, ON, Canada; Children's Hospital of Eastern Ontario Research Institute, University of Ottawa, Ottawa. Electronic address:

Purpose: Universal newborn hearing screening (UNHS) programs using audiometric techniques alone are limited in ability to detect non-congenital childhood permanent hearing loss (PHL). In 2019, Ontario launched universal newborn screening (NBS) for PHL risk factors: congenital cytomegalovirus (cCMV) and 22 common variants in GJB2 and SLC26A4. Here we describe our experience with genetic risk factor screening.

Purpose: MR-based FID navigators (FIDnavs) do not require gradient pulses and are attractive for prospective motion correction (PMC) due to short acquisition times and high sampling rates. However, accuracy and precision are limited and depend on a separate calibration measurement. Besides FIDnavs, stationary NMR field probes are also capable of measuring local, motion-induced field changes.

Background: Supraglottic squamous cell carcinoma (SCC) is a significant portion of head and neck cancers, with the management of clinically negative necks (cN0) through selective neck dissection (SND) being debated due to potential morbidities and low metastasis rates in levels IIb and IV.

Methods: This study is a retrospective, multicenter examination of the potential feasibility of limited neck dissection (LND), including only levels IIa and III in cN0 supraglottic SCC patients. It analyzed occult metastasis rates and explored relapse occurrences alongside potential predictors of lymph node metastasis.

Reductive Adjuvant Nanosystem for Alleviated Atopic Dermatitis Syndromes.

ACS Nano

January 2025

College of Pharmaceutical Sciences, Zhejiang University, 866 Yuhangtang Road, Hangzhou, Zhejiang 310058, P. R. China.

Atopic dermatitis (AD) is a recurrent and chronic inflammatory skin condition characterized by a high lifetime prevalence and significant impairment of patients' quality of life, primarily due to intense itching and discomfort. However, current pharmacological interventions provide only moderate efficacy and are frequently accompanied by adverse side effects. The immune-pathogenesis of AD involves dysregulation of the Th2 immune response and exacerbation of inflammation related to excessive reactive oxygen species (ROS).

Upper arm movements in the last days of life: A new possible sign of impending death.

Palliat Support Care

January 2025

Faculdade de Medicina da Universidade de Coimbra, Universidade de Coimbra, Coimbra, Portugal.

One of the most crucial stages of palliative care is the last days and hours of life, which require special attention and knowledgeable identification of clinical signs described as signs of impending death (SID). Our case series of 11 patients receiving home palliative care describes bilateral hypoactive, stereotyped upper arm movements (scratching of the head, forehead, and nose) that were previously unknown or described, often accompanied by SID.

Background: Scalp itch without evident cause is an uncomfortable symptom that annoys many people in life but lacks adequate attention in academic.

Aims: To investigate the relationship between scalp itching and microorganisms, and identify the key microbes and predicted functions associated with scalp itching, furtherly to provide useful targets for scalp itch solution.

Methods: We performed microbial comparison between 44 normal subjects and 89 subjects having scalp itching problem with un-identified origin based on 16S rRNA gene sequencing and ddPCR (digital droplet PCR), and identified itch relevant microbes and predicted functions.

Mycophenolate mofetil: an update on its mechanism of action and effect on lymphoid tissue.

Front Immunol

January 2025

Department of Pharmacology and Toxicology, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Olsztyn, Poland.

Introduction: Mycophenolate mofetil (MMF) is an immunosuppressive drug administered in the management of both autoimmune diseases and organ transplantation. The main aims of the study were: (a) to obtain information regarding the safety of using MMF in respect of its effect on normal T and B cells in lymphoid tissues; (b) to investigate whether the generation of inducible Foxp3-expressing regulatory T cells (Treg) might constitute additional mechanisms underlying the immunosuppressive properties of MMF.

Methods: The effect of MMF ( studies) and its active metabolite, mycophenolic acid, ( studies) on murine CD4 and CD8 T cells as well as B cells was determined, regarding: (a) absolute count, proliferation and apoptosis of these cells ( studies); (b) absolute count of these cells in the head and neck lymph nodes, mesenteric lymph nodes and the spleen ( studies).

Blood-based biomarkers have been revolutionizing the detection, diagnosis and screening of Alzheimer's disease. Specifically, phosphorylated-tau variants (p-tau, p-tau and p-tau) are promising biomarkers for identifying Alzheimer's disease pathology. Antibody-based assays such as single molecule arrays immunoassays are powerful tools to investigate pathological changes indicated by blood-based biomarkers and have been studied extensively in the Alzheimer's disease research field.

Giant rhinoliths are uncommon, mineralized concretions that usually develop around an intranasal foreign substance in the nasal canal. These lesions frequently cause respiratory problems, foul-smelling discharge, and nasal blockage. Clinical examination, endoscopy, and radiological imaging are used to make the diagnosis, and surgical removal is the only effective therapy.

is Expressed on the Left Side of the Brain Vesicle in the Ascidian Larva.

Dev Reprod

December 2024

Department of Marine Bioscience, Gangneung-Wonju National University, Gangneung 25457, Korea.

The ascidian larvae, which display a chordate ground body plan, are left-right asymmetric in several structures, including the brain vesicle. In ascidian larvae, the ocellus and otolith pigment cells, which are thought to detect light and gravity respectively, are located on the right side of the brain vesicle, while the coronet cells, which are presumed to be dopaminergic, are located on the left side. To study how left-right asymmetry of the brain vesicle in the ascidian larva is determined, I attempted to isolate a gene that is expressed in the brain vesicle.

Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.

Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.
