Background/aim: The oral bacteria involved in the development of periodontitis alter the tissue conditions and modify immune responses in a way that may also influence tumor development. We investigated the prevalence of R gingipain (Rgp), a key virulence factor of the oral pathobiont Porphyromonas gingivalis, and the tissue-destructive enzymes matrix metalloproteinase 8 (MMP-8) and 9 (MMP-9) in 202 unselected consecutive oropharyngeal squamous cell carcinoma (OPSCC) samples. We further investigated the relationships between these factors and human papillomavirus (HPV) status, Treponema denticola chymotrypsin-like proteinase (Td-CTLP) immunoexpression, clinical parameters, and patient outcome.

"Theory of Mechanisms and Robots" Department, Faculty of Industrial Engineering and Robotics, University Politehnica of Bucharest, Splaiul Independentei Street 313, 060042 Bucharest, Romania.

Utilizing solid wastes and industrial by-products as a partial replacement for raw materials has become an acceptable practice among researchers and scientists in the civil engineering field. Sawdust and wood shavings are not an exception; they are being used in concrete as a partial or total replacement for some of its constituents. The main goal of this research is to establish a relation between destructive and non-destructive testing for concrete containing wood shavings as a partial replacement of sand (woodcrete).

September 2021

Academic Unit of Child Health, Department of Oncology and Metabolism, University of Sheffield, Damer Street Building, Western Bank, Sheffield S10 2TH, United Kingdom; Radiology Department, Sheffield Children's NHS Foundation Trust, Western Bank, Sheffield, United Kingdom.

Background: Skeletal imaging techniques have become clinically valuable methods for measuring and assessing bone mineral density in children and young people. Dual-energy X-ray absorptiometry (DXA) is the current reference standard for evaluating bone density, as recommended by the International Society for Clinical Densitometry (ISCD). Various bone imaging modalities, such as quantitative ultrasound (QUS), peripheral quantitative computed tomography (pQCT), high-resolution peripheral quantitative computed tomography (HR-pQCT), magnetic resonance imaging (MRI), and digital X-ray radiogrammetry (DXR) have been developed to further quantify bone health in children and adults.

To obtain new anti-inflammatory agents, recent studies have aimed to replace the carboxylate functionality of nonsteroidal anti-inflammatory drugs with less acidic heterocyclic bioisosteres like 1,3,4-oxadiazole to protect the gastric mucosa from free carboxylate moieties. In view of these observations, we designed and synthesized a series of 3,5-disubstituted-1,3,4-oxadiazole derivatives as inhibitors of prostaglandin E (PGE ) and NO production with an improved activity profile. As initial screening, and to examine the anti-inflammatory activities of the compounds, the inhibitions of the productions of lipopolysaccharide-induced NO and PGE in RAW 264.

The year 2019 witnessed the first approval of an immune checkpoint inhibitor (ICI) for the management of triple negative breast cancers (TNBC) that are metastatic and programmed death ligand (PD)-L1 positive. Extensive research has focused on testing ICI-based combinatorial strategies, with the ultimate goal of enhancing the response of breast tumors to immunotherapy to increase the number of breast cancer patients benefiting from this transformative treatment. The promising investigational strategies included immunotherapy combinations with monoclonal antibodies (mAbs) against human epidermal growth factor receptor (HER)-2 for the HER2 + tumors versus cyclin-dependent kinase (CDK)4/6 inhibitors in the estrogen receptor (ER) + disease.

Exploratory investigation on the antibacterial effect of antimicrobial peptides of four mammalian plasmas.

Microb Pathog

July 2021

Omar Al-Mukhtar University, Faculty of Science, Department of Microbiology, Box 919, Al-Bayda, Libya; Omar Al-Mukhtar University, Faculty of Medical Technology, Box 919, Al-Bayda, Libya. Electronic address:

Antimicrobial peptides (AMPs) are presently being revisited as promising potential antimicrobial combat agents. Acquisition of resistance to AMPs is very rare compared to conventional antibiotics as they kill microbes by direct disruption of cellular components including the microbial membrane and DNA. In this study four sources of mammalian plasma (human, bovine, caprine and ovine) were explored for presence and effectiveness of antimicrobial peptides by the spot-on-lawn method, followed by the agar well diffusion assay to confirm their antibacterial activity.
