Comparative in vitro activity of selected antibacterial agents against Escherichia coli isolated from hospitalized patients suffering UTI.

Escherichia coli is the most studied among those bacteria causing urinary tract infections. This study was aimed to find out antibacterial activity and minimum inhibitory concentration of selected antibacterial agents against E. coli isolates of hospitalized UTI patients.

Differentiation of Brain Tumor Microvasculature From Normal Vessels Using Optical Coherence Angiography.

Background And Objectives: Despite rapid advances and discoveries in medical imaging, monitoring therapeutic efficacy for malignant gliomas and monitoring tumor vasculature remains problematic. The purpose of this study is to utilize optical coherence angiography for vasculature characterization inside and surrounding brain tumors in a murine xenograft brain tumor model. Features included in our analysis include fractional blood volume, vessel tortuosity, diameter, orientation, and directionality.

Multimodal imaging of skin lesions by using methylene blue as cancer biomarker.

This study aimed the optical imaging of malignant and normal skin tissues with multimodal wide-field fluorescence polarization imaging (WF) technique, by using methylene blue as fluorescence dye. We present optical imaging of skin tissues by different techniques, including reflectance, fluorescence, and polarization imaging for early detection of skin cancer. We collected the reflectance confocal images at 390 and 500 nm.

Hemoglobin structure at higher levels of hemoglobin A1C in type 2 diabetes and associated complications.

Background: Fourier transform infrared (FTIR) spectroscopy technique has not been used as a diagnostic tool for diabetes in clinical practice. This study was linked to structural changes in hemoglobin (Hb) in type 2 diabetes patients at higher levels of HbA1C using FTIR spectroscopy.

Methods: Fifty-three diabetic patients from the Bahawal Victoria Hospital, Bahawalpur, Pakistan were categorized as group A (6% < HbA1C < 7%; n = 25) and group B (HbA1C ≥9%; n = 28).

Hematological complications under hyper conditions of glucose and distilled water.

This work presents a pilot method of hematological diagnosis about changes in: shape, size and rouleaux formation, cell count of leucocytes and platelet cells in the presence of different glucose [CHO] and water [H2O] concentrations. The 2D microscopic images after addition of ten different glucose concentrations to normal blood (0 mM- 450 mM) revealed the lyses (disintegration) of white blood cells (WBCs). This work provides a baseline to diagnose blood disorders and complications at labs and clinical environment.

Attenuated total reflectance spectroscopy to diagnose skin cancer and to distinguish different metastatic potential of melanoma cell.

Early diagnosing of skin cancer and investigation of metastatic potential of cancer cells are very important to treat it appropriately. Infrared spectroscopy of biological tissues is an emerging technique which gives the spectral differences between healthy and diseased cells. In this work, we have demonstrated that attenuated total reflectance Fourier transform (ATR-FTIR) spectroscopy can be used in diagnostic of skin cancer and in differentiating metastatic potential of cancer cells.
