Oxidative stress has been connected to various forms of cardiovascular diseases. Previously, we have been investigating the potential of new nitrogen-containing synthetic compounds using a neuronal cell model and different oxidative stress conditions in order to elucidate their potential to ameliorate neurodegenerative diseases. Here, we intended to extend these initial studies and investigate the protective role of four of those new synthetic compounds (FMA4, FMA7, FMA762 and FMA796) against oxidative damage induced to H9c2 cardiomyoblasts by tert-butylhydroperoxide (t-BHP). The data indicates that FMA762 and FMA796 decrease t-BHP-induced cell death, as measured by both sulforhodamine B assay and nuclear chromatin condensation evaluation, at non-toxic concentrations. In addition, the two mentioned compounds inhibit intracellular signalling mechanisms leading to apoptotic cell death, namely those mediated by mitochondria, which was confirmed by their ability to overcome t-BHP-induced morphological changes in the mitochondrial network, loss of mitochondrial membrane potential, increased expression of the pro-apoptotic proteins p53, Bax and AIF and activation of caspases-3 and -9. Importantly, our results indicate that the compounds' ROS scavenging ability plays a crucial role in the protection profile, as a significant decrease in t-BHP-induced oxidative stress occurred in their presence. Data obtained indicates that some of the test compounds may clearly prove valuable in a clinical context by diminishing cardiac injury associated to oxidative stress without any toxicity.

Introduction/objective: Emotional, mental, or psychological distress, defined as increased symptoms of depression, anxiety, and/or stress, is common in patients with chronic diseases, such as cardiovascular (CV) disease (CVD).
Methods: Literature was reviewed regarding data from studies and meta-analyses examining the impact of emotional stress on the occurrence and outcome of several CVDs (coronary disease, heart failure, hypertension, arrhythmias, stroke). These influences' pathophysiology and clinical spectrum are detailed, tabulated, and pictorially illustrated.

Immune checkpoint blockade (ICB) has fundamentally transformed cancer treat-ment by unlocking the potency of CD8+ T cells by targeting the suppression of the CTLA-4 and PD-1/PD-L1 pathways. Nevertheless, ICBs are associated with the risk of severe side effects and resistance in certain patients, driving the search for novel and safer immune check-point modulators. Monoamine Oxidase A (MAO-A) plays an unexpected role in the field of cancer.

Background: This study aimed to evaluate the effects of administering flunixin meglumine (FM) and meloxicam (M) on specific days post-mating on progesterone (P4), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), pregnancy-specific protein B (PSPB), pregnancy-associated glycoprotein (PAG) concentrations and fertility parameters in Awassi sheep.
Methods: Seventy-five Awassi sheep were divided into three groups of 25: control, M and FM. On days 9 and 10 post-mating, the control group received saline, the M group received 0.

Atopic dermatitis (AD) is a chronic skin inflammatory ailment commonly observed in young children and adults. Various therapeutic modalities are already explored for mitigation of AD but for prolong application very few modalities are recommended. Considering these challenges, we have successfully developed gliclazide-loaded hydrogels using the physical dispersion method.
