Autophagy and extracellular vesicles mediate cisplatin resistance in oral squamous cell carcinoma with LC3B-II as a potential non-invasive biomarker

Drug resistance remains a critical challenge in cancer chemotherapy, particularly in oral squamous cell carcinoma (OSCC). Recent findings have highlighted the significant roles that autophagy and extracellular vesicles (EVs) play in contributing to chemoresistance. In previous studies, we demonstrated that EVs are essential in mediating cisplatin resistance in human OSCC cells. In this study, we s

Leveraging Landsat and Google Earth Engine for long-term chlorophyll-a monitoring : A case study of Lake Balaton's water quality

Chlorophyll-a (Chl-a) is one of the critical water quality indicators that shows the eutrophication status of aquatic ecosystems. As the largest lake and a well-known attraction in middle Europe, Lake Balaton contributes 70 % or more of local economy through tourism, while also maintaining a unique biodiversity. Therefore, long-term monitoring of water quality is essential for its effective manage

Effects of COVID-19 lockdowns on unintended pregnancies among adolescent girls and young women in low- and middle-income countries : a scoping review

Background: The response to the COVID-19 pandemic involved various lockdown measures, including school closures, which significantly impacted young populations, particularly in low-and middle-income countries (LMICs). Given the well-known protective effect of regular school attendance on sexual and reproductive health and rights (SRHR), reports of disrupted education, compromised SRHR, and an incr

Health and social care staff’s experiences working with adults with complex needs – a focus group study

Background: Multimorbidity is increasing globally, affecting over one-third of the population. Adults with complex needs often experience physical, mental, and cognitive disorders, leading to increased healthcare utilization, reduced quality of life, and social challenges. The frequent co-occurrence of psychiatric conditions, substance abuse, addiction, and homelessness highlights the complexity o

Differential memory enrichment of cytotoxic CD4 T cells in Parkinson’s disease patients reactive to α-synuclein

Parkinson’s disease (PD) is a complex neurodegenerative disease with a largely unknown etiology. Although the loss of dopaminergic neurons in the substantia nigra pars compacta is the pathological hallmark of PD, neuroinflammation also plays a fundamental role in PD pathology. We have previously reported that PD patients have increased frequencies of T cells reactive to peptides from α-synuclein (

Glucose-6-phosphate-dehydrogenase on old peroxisomes maintains self-renewal of epithelial stem cells after asymmetric cell division

Selective inheritance of sub-cellular components has emerged as a mechanism guiding stem cell fate after asymmetric cell divisions. Peroxisomes play a crucial role in multiple metabolic processes such as fatty acid metabolism and reactive oxygen species detoxification, but the apportioning of peroxisomes during stem cell division remains understudied. Here, we develop a mouse model and labeling te

Stress granules : emerging players in neurodegenerative diseases

Stress granules (SGs) are membraneless organelles formed in the cellular cytoplasm under stressful conditions through liquid–liquid phase separation (LLPS). SG assembly can be both dependent and independent of the eIF2α pathway, whereas cellular protein quality control systems mediate SG disassembly. Chaperones and specific domains of RNA-binding proteins strongly contribute to the regulation SG d

A feasibility and safety trial investigating a device for swift and standardized median laparotomy closure

Purpose: Abdominal wall complications can be reduced by adhering to guidelines for midline laparotomy closure. However, implementation of guidelines can be challenging. To address this issue, a laparotomy closure device for swift and standardized abdominal closure was developed. The study evaluated the quality of the suture, safety, and speed of the device in a clinical setting. Methods: A prospec

Differential effects of aging, Alzheimer's pathology, and APOE4 on longitudinal functional connectivity and episodic memory in older adults

Background: Both aging and Alzheimer's disease (AD) affect brain networks, with early disruptions occurring in regions involved in episodic memory. Few studies have, however, focused on distinguishing region-specific effects of AD-biomarker negative “normal” aging and early amyloid- and tau pathology on functional connectivity. Further, longitudinal studies combining imaging, biomarkers, and cogni

CXCL12 links bladder cancer and diabetes as a potential biomarker

Bladder cancer (BLCA) and diabetes mellitus (DM) are two prevalent diseases that may share molecular mechanisms, suggesting potential links between metabolic disorders and cancer. Using bioinformatics approaches, we integrated multiple databases to identify common genes between BLCA and DM, screening for potential biomarkers. CXCL12 (C-X-C motif chemokine 12, also known as stromal cell-derived fac

Predictors of time to recovery from cataract surgery among cataract patients at Menelik II Comprehensive Specialized Hospital : a retrospective follow up study

Background: Cataracts are the leading cause of reversible blindness globally, disproportionately affecting populations in low- and middle-income countries. In Ethiopia, cataracts remain a significant public health concern. Despite the effectiveness of cataract surgery in restoring vision, information on recovery time and its predictors remain limited. The aim of this study was to assess time to re

Commissioning of the Multipole Injection Kicker in the MAX IV 1.5 GeV ring

The Multipole Injection Kicker (MIK) installed in the 3 GeV ring of MAX IV, is a success story in the use of a non-linear field device ensuring an almost transparent injection into the first ever built fourth-generation storage ring. Reducing the transient stored beam perturbations during top-up injections is particularly relevant for such machines operating at emittances in the regime of few hund

No socioeconomic disparities in the availability of personal care assistance : a population-based cohort analysis of children living with respiratory support

Background: Children aged 0–18 years who need long-term respiratory support rely on medical technology and comprehensive medical care. For this care to be provided at home, access to medical and social support and care is essential. In Sweden, the most notable form is personal care assistance (PCA), which is granted based on legislation and individual authority decisions. We aim to explore the imp

Calprotectin as a sepsis diagnostic marker in critical care : a retrospective observational study

Diagnosing sepsis in critical care remains a challenge due to the lack of gold-standard diagnostics. Calprotectin (S100A8/A9) has been proposed as a diagnostic marker to identify sepsis in critically ill patients. This study evaluated the diagnostic performance of calprotectin and C-reactive protein (CRP) to distinguish between sepsis and non-sepsis on intensive care unit (ICU) admission. Admissio

Duality and degeneracy lifting in two-dimensional electron liquids on SrTiO3(001)

Two-dimensional electron liquids (2DELs) have increasing technological relevance for ultrafast electronics and spintronics, yet significant gaps in their fundamental understanding are exemplified on the prototypical SrTiO3. We correlate the exact SrTiO3(001) surface structure with distinct 2DELs through combined microscopic angle-resolved photoemission spectroscopy and non-contact atomic force mic
