Signal growth in a pure time-modulated transmission line and the loss effect.

We present the first comprehensive study for signal growth in transmission lines (TL) with purely time-modulated characteristic impedance (infinite superluminality). This study pioneers the investigation into the effects of varying the cell's electrical length and the impact of loss on momentum bandgaps and amplification levels. It also thoroughly examines how time-modulated transmission line truncation by a static load influences the sensitivity of amplification gain to the relative phase between the incoming signal and modulation, comparing these findings with the case of parametric amplification.

Molecular evaluation of early-age plasma adiponectin levels in young obese cases with diabetes mellitus type 1.

Objectives: Adiponectin (ADN) is related to insulin resistance and cardiovascular disorders risks. It is negatively controlled in obese cases among diabetes mellitus type 1 (DMT1) patients. The current study evaluates ADN levels in early-aged children 9-12 years old of obese and non-obese cases (DMT1).

Innovative model of surface-enhanced Raman spectroscopy for exosomes identification: An approach for the diagnosis of hepatocellular carcinoma.

Background: The current hepatocellular carcinoma (HCC) diagnostic approaches lack adequate sensitivity and specificity. So, this study was performed to develop an innovative model of surface-enhanced Raman spectroscopy (SERS) that can detect HCC patients by identifying the circulating tumor-derived exosomes.

Methodology: Sixty participants, including normal controls, hepatitis C virus (HCV)-infected patients, and HCV-associated HCC patients, had their whole blood samples and exosomes separated from these samples analyzed using Raman spectroscopy (RS).

Early and Midterm Results of Stent Endarterectomy for Left Anterior Descending Coronary Artery "Full Metal Jacket".

Objective: Modern coronary interventional practice can result in coronary vessels that are totally stented. The term "full metal jacket" has been coined to refer to vessels that have an overlapping stent in series along the whole length of the vessel. This poses a serious challenge to surgical revascularization, particularly when a left internal thoracic artery (LITA) to the left anterior descending (LAD) needs to be undertaken.

The Impact of Royal Jelly against Hepatic Ischemia/Reperfusion-Induced Hepatocyte Damage in Rats: The Role of Cytoglobin, Nrf-2/HO-1/COX-4, and P38-MAPK/NF-κB-p65/TNF-α Signaling Pathways.

Objective: The present study was conducted to elucidate the underlying molecular mechanism as well as the potential hepatoprotective effects of royal jelly (RJ) against hepatic ischemia/ reperfusion (IR) injury.

Methods: Rats were assigned into four groups; sham (received vehicle), IR (30 minutes ischemia and 45 minutes reperfusion), sham pretreated with RJ (200 mg/kg P.O.

Moderate ischemic mitral incompetence: does it worth more ischemic time?

Objectives: Ischemic mitral regurgitation (IMR) is a common finding following myocardial infarction or ischemia. Management of moderate IMR is still a hot topic. Adding mitral valve repair (MVr) to coronary artery bypass grafting (CABG) is questionable.

If post-thoracotomy pain is the target, Integrated Thoracotomy is the choice.

Objectives: Despite the overgrowth of procedures done by VATS, there are still needs for thoracotomy. Post-thoracotomy pain plays an important role in many post-operative morbidities. Surgeons should make efforts to evolve new techniques to reduce post-thoracotomy pain with its associated morbidities.

Serum circulating cell free DNA as potential diagnostic and prognostic biomarker in non small cell lung cancer.

Background: Non-small cell lung cancer (NSCLC) is leading cause of cancer related death and the survival rate for patients with NSCLC remain poor so early diagnosis of NSCLC represents the best opportunity for cure. Cell-free DNA (cf-DNA) is extracellular nucleic acids found in cell-free plasma/serum of humans, given the recent approval of a liquid biopsy in lung cancer, the use of circulating tumor DNA as a novel non-invasive diagnostic and prognostic biomarker is promising.

Objectives: Studying whether the concentrations of circulating Cell Free DNA in serum can be used as a diagnostic and prognostic biomarker for NSCLC patients.
