Institute for Risk Assessment Sciences (IRAS), Faculty of Veterinary Medicine, Utrecht University, P.O. Box 80.177, 3508TD Utrecht, the Netherlands. Electronic address:

Physiologically-based kinetic (PBK) models can simulate concentrations of chemicals in tissues over time without animal experiments. Nevertheless, in vivo data are often used to parameterise PBK models. This study aims to illustrate that a combination of kinetic and dynamic readouts from in vitro assays can be used to parameterise PBK models simulating neurologically-active concentrations of xenobiotics.

Centre for Host-Microbiome Interactions, Faculty of Dentistry, Oral & Craniofacial Sciences, King's College London, London, SE1 9RT, UK; Science for Life Laboratory, KTH - Royal Institute of Technology, Stockholm, SE-17121, Sweden. Electronic address:

Glioblastoma (GB) is the most common and aggressive primary malignant astrocytoma correlated with poor patient survival. There are no curative treatments for GB, and it becomes resistant to chemotherapy, radiation therapy, and immunotherapy. Resistance in GB cells is closely related to their states of redox imbalance, and the role of reactive oxygen species and its impact on cancer cell survival is still far from elucidation. Read More

Measuring Postprandial Metabolic Flexibility To Assess Metabolic Health and Disease.

J Nutr 2021 Jul 22. Epub 2021 Jul 22.

Hubert Department of Global Health, Rollins School of Public Health, Emory University, Atlanta, Georgia, USA.

Metabolic abnormalities substantially increase the risk of noncommunicable diseases, which are among the leading causes of mortality globally. Mitigating and preventing these adverse consequences remains challenging due to a limited understanding of metabolic health. Metabolic flexibility, a key tenet of metabolic health, encompasses the responsiveness of interrelated pathways to maintain energy homeostasis throughout daily physiologic challenges, such as the response to meal challenges.

Cefaclor-induced hypersensitivity: Differences in the incidence of anaphylaxis relative to other 2nd and 3rd generation cephalosporins.

PLoS One 2021 22;16(7):e0254898. Epub 2021 Jul 22.

Ajou Regional Pharmacovigilance Center, Ajou University Hospital, Suwon, Korea.

Cefaclor, a second-generation oral cephalosporin, is the most frequently prescribed cephalosporin in Korea. Studies, however, have yet to analyze the incidence of cefaclor-associated adverse drug reactions (ADRs), including hypersensitivity (HS), according to total national usage rates. This study aimed to investigate the incidence rates and clinical features of cefaclor ADRs reported to the Korean Adverse Event Reporting System (KAERS) and Health Insurance Review and Assessment Service (HIRA) database for the most recent 5 years.

Fungal species in endodontic infections: A systematic review and meta-analysis.

PLoS One 2021 22;16(7):e0255003. Epub 2021 Jul 22.

College of Dental Medicine, University of Sharjah, Sharjah, UAE.

Fungal infections are common on oral mucosae, but their role in other oral sites is ill defined. Over the last few decades, numerous studies have reported the presence of fungi, particularly Candida species in endodontic infections, albeit in relatively small numbers in comparison to its predominant anaerobic bacteriome. Here, we review the fungal biome of primary and secondary endodontic infections, with particular reference to the prevalence and behavior of Candida species. Read More

Miltefosine enhances infectivity of a miltefosine-resistant Leishmania infantum strain by attenuating its innate immune recognition.

PLoS Negl Trop Dis 2021 Jul 22;15(7):e0009622. Epub 2021 Jul 22.

University of Antwerp, Department of Biomedical Sciences, Laboratory of Microbiology, Parasitology and Hygiene (LMPH), Wilrijk, Belgium.

Background: Miltefosine (MIL) is currently the only oral drug available to treat visceral leishmaniasis but its use as first-line monotherapy has been compromised by an increasing treatment failure. Despite the scarce number of resistant clinical isolates, MIL-resistance by mutations in a single aminophospholipid transporter gene can easily be selected in a laboratory environment. These mutations result in a reduced survival in the mammalian host, which can partially be restored by exposure to MIL, suggesting a kind of drug-dependency. Read More

Predictors of use of dental care by children in north-central Appalachia in the USA.

PLoS One 2021 22;16(7):e0250488. Epub 2021 Jul 22.

Center for Oral Health Research in Appalachia, Appalachia, New York, United States of America.

Use of dental services in childhood, especially preventive care, is associated with many important oral health outcomes throughout life. The Andersen behavioral model of healthcare utilization posits that predisposing characteristics, enabling resources, and need factors predict utilization in oral and other healthcare domains. Inequities that produce lower utilization of dental services in north-central Appalachia have been documented in comparison to the USA generally. Read More

Fertility-sparing approach for endometrial cancer: the role of office hysteroscopy.

Minim Invasive Ther Allied Technol 2021 Jul 22:1-8. Epub 2021 Jul 22.

Department of Obstetrics and Gynecology, University of California Davis Medical Center, Sacramento, CA, USA.

Endometrial cancer is the most common gynecologic malignancy in developed countries, with increasing incidence among younger, nulliparous patients. These epidemiological shifts are attributed to increasing rates of obesity, in combination with delayed childbearing. This highlights a need for fertility-sparing options for individuals who wish to delay standard surgical management with hysterectomy, bilateral salpingoophorectomy, and assessment of pelvic/para-aortic lymph nodes.

Colon-Targeted Adhesive Hydrogel Microsphere for Regulation of Gut Immunity and Flora.

Adv Sci (Weinh) 2021 Jul 22:e2101619. Epub 2021 Jul 22.

Department of Orthopaedics, Shanghai Key Laboratory for Prevention and Treatment of Bone and Joint Diseases, Shanghai Institute of Traumatology and Orthopaedics, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, 197 Ruijin 2nd Road, Shanghai, 200025, P. R. China.

Intestinal immune homeostasis and microbiome structure play a critical role in the pathogenesis and progress of inflammatory bowel disease (IBD), whereas IBD treatment remains a challenge as the first-line drugs show limited therapeutic efficiency and great side effect. In this study, a colon-targeted adhesive core-shell hydrogel microsphere is designed and fabricated by the ingenious combination of advanced gas-shearing technology and ionic diffusion method, which can congregate on colon tissue regulating the gut immune-microbiota microenvironment in IBD treatment. The degradation experiment indicates the anti-acid and colon-targeted property of the alginate hydrogel shell, and the in vivo imaging shows the mucoadhesive ability of the thiolated-hyaluronic acid hydrogel core of the microsphere, which reduces the systematic exposure and prolongs the local drug dwell time.

Photothermal-Enhanced Fenton-like Catalytic Activity of Oxygen-Deficient Nanotitania for Efficient and Safe Tooth Whitening.

ACS Appl Mater Interfaces 2021 Jul 22. Epub 2021 Jul 22.

State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases & Engineering Research Center of Oral Translational Medicine, Ministry of Education & National Engineering Laboratory for Oral Regenerative Medicine, West China Hospital of Stomatology, Sichuan University, Chengdu 610041, China.

The growing demand for charming smiles has led to the popularization of tooth bleaching procedures. Current tooth bleaching products with high-concentration hydrogen peroxide (HP, 30-40%) are effective but detrimental due to the increased risk of enamel destruction, tooth sensitivity, and gingival irritation. Herein, we reported a less-destructive and efficient tooth whitening strategy with a low-concentration HP, which was realized by the remarkably enhanced Fenton-like catalytic activity of oxygen-deficient TiO (TiO).
