Background: Doxorubicin (DOX) drugs used in cancer treatment can cause various adverse effects, including hepatotoxicity. Natural-derived constituents have shown promising effects in alleviating chemotherapy-induced toxicities. This study addressed the effect of Avenanthramides-C (AVN-C) treatment in rats with DOX-indued hepatotoxicity.

Doxorubicin (DOX), an anticancer drug, is used to treat several types of tumors, but it has detrimental side effects that restrict its therapeutic efficacy. One is the iron-dependent form of ferroptosis, which is characterized by elevated ROS production and iron overload. has a diverse range of biological and pharmaceutical actions due to their antioxidant properties.

Atorvastatin (ATOR) acts on certain antitumor pathways; the consequences of chemotherapies continue to be a major concern, notwithstanding the increased efficacy provided by contemporary therapies. This study investigated the synergistic effects and underlying mechanisms of different treatment protocols using ATOR on the THP-1 cell line and on lung cancer in mice. For the in vitro study, an MTT assay was performed, and then different combinations against the THP-1 cell line were used as follows: non-treated cells, THP-1/ATOR IC, THP-1/cytarabine (CYT) IC, THP-1/doxorubicin (DOX) IC, THP-1/DOX/CYT, THP-1/ATOR/CYT, THP-1/ATOR/DOX, and THP-1/ATOR/CYT/DOX.

Translation is a fundamental process in biology, and understanding its mechanisms is crucial to comprehending cellular functions and diseases. The regulation of this process is closely linked to the structure of mRNA, as these regions prove vital to modulating translation efficiency and control. Thus, identifying and investigating these fundamental factors that influence the processing and unwinding of structured mRNAs would be of interest due to the widespread impact in various fields of biology.

Introduction: The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in regulating blood pressure (BP), with dysregulation of RAAS resulting in hypertension and potentially heart failure (HF), myocardial infarction (MI), cardio-renal syndrome, and stroke. RAAS inhibitors, such as angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs), have advantages beyond BP control. However, differences between these two drug classes need to be considered when choosing a therapy for preventing cardiovascular events.

Background: Heart failure (HF) poses a major health problem, where frequent HF rehospitalizations (HFH) heavily burden national health systems. HFH are predominantly linked to inadequate decongestion before discharge. It is uncertain if systematic implementation of cardio-pulmonary ultra-sound imaging (CPUSI) to standard HF management can improve outcomes and reduce HFH.

Maintaining cellular homeostasis in the face of stress conditions is vital for the overall well-being of an organism. Reactive oxygen species (ROS) are among the most potent cellular stressors and can disrupt the internal redox balance, giving rise to oxidative stress. Elevated levels of ROS can severely affect biomolecules and have been associated with a range of pathophysiological conditions.

Article Synopsis
  • Managing chronic hepatitis B virus (HBV) infection is essential for the goal of eliminating viral hepatitis by 2030, but challenges like medication access and adherence issues persist.* -
  • A specific case study highlights a patient with both HBV and HIV who faced virological breakthrough despite receiving nucleos/tide analogue therapy due to factors like high viral load and interruptions in therapy.* -
  • The situation illustrates the need for personalized treatment plans and better support systems, especially for marginalized groups, along with comprehensive data collection to enhance patient care and retention.*

Article Synopsis
  • Worsening renal function (WRF) is common in patients with acute decompensated heart failure (ADHF) and indicates a higher risk of negative outcomes, with a potential connection to abdominal congestion that needs further investigation.
  • A study involving 100 ADHF patients assessed factors like intra-abdominal pressure and splenic Doppler indices to predict WRF, defining it as a rise in serum creatinine levels.
  • Results showed that 37% of patients developed WRF, with significant predictors identified as high splenic resistivity index, elevated intra-abdominal pressure, and low left ventricular ejection fraction during hospitalization.

The agricultural fungicide cymoxanil (CMX) is commonly used in the treatment of plant pathogens, such as Phytophthora infestans. Although the use of CMX is widespread throughout the agricultural industry and internationally, the exact mechanism of action behind this fungicide remains unclear. Therefore, we sought to elucidate the biocidal mechanism underlying CMX.

Using Density Functional Theory (DFT) and Time Dependent DFT (TD-DFT) methods, this inquiry theoretically examines seven novel hole-transport materials (HTMs) namely DFBT1, DFBT2, DFBT3, DFBT4, DFBT5, DFBT6, and DFBT7 based on the 2,2'bithiophene core for future use as HTMs for perovskite solar cells (PSCs). The model molecule has been modified through substituting the end groups situated on the diphenylamine moieties with a tow acceptor bridged by thiophene, this modification was performed to test the impact of the π-bridge and acceptor on the electronic, photophysical, and photovoltaic properties of the newly created molecules. DFBT1 - DFBT7 displayed a lower band gap (1.
