Time scale theory on stability of explicit and implicit discrete epidemic models: applications to Swine flu outbreak.

J Math Biol

December 2023

Department of Mathematics and Statistics, Computational Science Research Center, Viral Information Institute, San Diego State University, San Diego, CA, 92182, USA.

Time scales theory has been in use since the 1980s with many applications. Only very recently, it has been used to describe within-host and between-hosts dynamics of infectious diseases. In this study, we present explicit and implicit discrete epidemic models motivated by the time scales modeling approach.

Article Synopsis
  • Consumers are exposed to various chemical mixtures daily through food, water, and products, but risk assessments typically focus on single substances rather than mixtures.
  • To address this issue, a new approach simulates real-life chemical exposure scenarios, emphasizing the impact of long-term exposure to mixtures, particularly pesticides.
  • The study conducted on Sprague Dawley rats investigates the cumulative effects of pesticide mixtures at different doses over 90 days, with a focus on how these exposures might influence miRNA levels as potential biomarkers for health effects.

Department of Occupational Health and Safety, Hamidiye Health Sciences Faculty, University of Health Sciences, Istanbul, Turkey.

Trace elements are cofactors in various enzymes in the antioxidant defense and cell homeostasis required in the tissue during inflammation. In acute kidney injury induced by lipopolysaccharide (LPS), renal cells are affected by cytotoxicity. Renal evacuation and gastrointestinal absorption rates are important in regulating plasma levels of trace elements.

Surg Endosc

December 2023

Department of Computer Engineering, Faculty of Architecture and Engineering, Izmir Bakircay University, İzmir, Turkey.

Background: This study explores the application of machine learning (ML) in analyzing endobronchial ultrasound (EBUS) images for the detection of lymph node (LN) malignancy, aiming to augment diagnostic accuracy and efficiency. We investigated whether ML could outperform conventional classification systems in identifying malignant involvement of LNs, based on eight established sonographic features.

Methods: Retrospective data from two tertiary care hospital bronchoscopy units were utilized, encompassing healthcare reports of patients who had undergone EBUS between January 2017 and March 2023.

Introduction: Accessory pathway (AP) ablation is a straightforward approach with high success rates, but the fluoroscopy time (FT) is significantly longer in conventional technique. Electroanatomical mapping systems (EMS), reduce the FT, but anatomical and activation mapping may prolong the procedure time (PT). The fluoroscopy integration module (FIM) uses prerecorded fluoroscopy images and allows ablation similar to conventional technique without creating an anatomical map.

Pyrethroids (PYRs) may act as endocrine disrupters and lead to infertility. The aim of the study was to analyze the levels of anti-androgenic PYRs (cypermethrin, deltamethrin, and permethrin) and 3-phenoxy benzoic acid (3-PBA), a general metabolite of PYRs, in both semen and urine samples of men with oligozoospermia. The PYRs and 3-PBA metabolite levels in the semen and urine samples of the men were analyzed through GC-MS.

Despite effective therapies for those at risk of osteoporotic fracture, low adherence to screening guidelines and limited accuracy of bone mineral density (BMD) in predicting fracture risk preclude identification of those at risk. Because of high adherence to routine mammography, bone health screening at the time of mammography using a digital breast tomosynthesis (DBT) scanner has been suggested as a potential solution. BMD and bone microstructure can be measured from the wrist using a DBT scanner.

Greater tuberosity medial malposition: does it affect shoulder abductor moment?

Int Orthop

January 2024

Orthopaedics and Traumatology Department, Giresun University Faculty of Medicine, Gazipaşa Yerleşkesi Debboy Mevkii P.K.:28200 Merkez, Giresun, Turkey.

Purpose: The detrimental effect of greater tuberosity malposition on functional scores is well known. Superior or posterior malpositions exceeding five mm lead to excessive loading on the deltoid strength. However, the significance of situations where greater tuberosity becomes medialized due to the compressive effect of the locking plate fixation, especially in fractures with metaphyseal dead space, has not been emphasized.
