Advancement in piezoelectric nanogenerators for acoustic energy harvesting.

The demand for sustainable energy sources to power small electronics like IoT devices has led to exploring innovative solutions like acoustic energy harvesting using piezoelectric nanogenerators (PENGs). Acoustic energy harvesting leverages ambient noise, converting it into electrical energy through the piezoelectric effect, where certain materials generate an electric charge in response to mechanical stress or vibrations. This review paper provides a comprehensive analysis of the advancements in PENG technology, emphasizing their role in acoustic energy harvesting.

Genetic polymorphism of the CYP11B2 gene in an Iraqi patient with essential hypertension.

Objective: Aim: To demonstrate the genetic variant of CYP11B2 Gen rs1799998 and rs4539 and their ef f ect on systolic and diastolic blood pressure in Iraqi patient with essential hypertension in Aldiwania province.

Patients And Methods: Materials and Methods: This is an observational cross sectional descriptive single centre study for hypertensive patients at Al-Diwaniyah province, Iraq which is diagnosed according to 2020 ISH. All candidate patients were diagnosed and recruited by specialist caregiving physician/ cardiologist.

Association between plasma angiotensinogen level and response to valsartan among sample of Iraqi hypertensive patients.

Objective: Aim: The main aim of the present paper is to investigate allele frequencies of rs1799983 polymorphism eNOS genes and to determine association between rs1799983 polymorphism of eNOS gene and essential hypertension in Iraqi hypertensive patients.

Patients And Methods: Materials and Methods: Data obtained at the Al-Diwaniyah teaching hospital in Iraq by researchers from the Department of Pharmacology and Therapeutics in the College of Medicine at University of Al-Qadisiyah from July 2022 to July 2023. All participants (aged 20 to 70) had been taking valsartan 160 mg once day for essential hypertension for at least two weeks before to the study.

Radiation dose to health care workers measured by thermoluminescent dosimetry.

Aim: To evaluate radiation dose among physicians, nurses, nuclear medicine (NM) technicians, and radiographers at a single institution and to compare the difference in the measured dose during COVID-19 with other periods.

Materials And Methods: A retrospective analysis of the occupational radiation doses received by all workers in diagnostic radiography and NM departments at a single institution during a 5-year period (2018-2022) was performed. Dose measurements were recorded for 94 radiology personnel: radiographers, NM technicians, physicians, and nurses.

Triboelectric nanogenerator based on silane-coupled LTA/PDMS for physiological monitoring and biomechanical energy harvesting.

Energy harvesting from ambient sources present in the environment is essential to replace traditional energy sources. These strategies can diversify the energy sources, reduce maintenance, lower costs, and provide near-perpetual operation of the devices. In this work, a triboelectric nanogenerator (TENG) based on silane-coupled Linde type A/polydimethylsiloxane (LTA/PDMS) is developed for harsh environmental conditions.
