Background: Public healthcare practices, particularly disease prevention, screening, diagnosis, treatment, and rehabilitation of patients, heavily rely on the availability and functionality of medical equipment. The absence of sufficient medical equipment and the malfunctioning of existing equipment impede the ability to provide effective healthcare services and directly affect patient rehabilitation, while the challenges related to medical equipment utilization are huge, especially in countries with limited resources such as Ethiopia. Therefore, this study aimed to assess the availability, functionality, and barriers associated with the use of medical equipment at public comprehensive specialized hospitals in Amhara Regional State, Ethiopia.

Major Depressive Disorder (MDD) is a common and severe neuropsychiatric condition resulting in irregular alterations in affect, mood, and cognition. Besides the well-studied neurotransmission-related etiologies of MDD, several biological systems and phenomena, such as the hypothalamic-pituitary-adrenal (HPA) axis, reactive oxygen species (ROS) production, and cytokine signaling, have been implicated as being altered and contributing to depressive symptoms. However, the manner in which these factors interact with each other to induce their effects on MDD development has been less clear, but is beginning to be understood.

Center for Global Health Research, Saveetha Medical College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai, India.

Cardiovascular illnesses are multifactorial disorders and represent the primary reasons for death worldwide, according to the World Health Organization. As a signaling molecule, nitric oxide (NO) is extremely permeable across cellular membranes owing to its unique molecular features, like its small molecular size, lipophilicity, and free radical properties. Some of the biological effects of NO are vasodilation, inhibition in the growth of vascular smooth muscle cells, and functional regulation of cardiac cells.

Sympathetic nerve signaling rewires the tumor microenvironment: a shift in "microenvironmental-ity".

Cancer Metastasis Rev

January 2025

Cancer Early Detection Advanced Research Center (CEDAR), Knight Cancer Institute, Oregon Health and Science University, Portland, OR, USA.

Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.
