Stroke is the second most common cause of death worldwide. It occurs due to the insufficient supply of oxygen-rich blood to the brain. It is a complex disease with multiple associated risk factors including smoking, alcoholism, age, sex, ethnicity, etc. Calcium ions are known to play a vital role in cell death pathways, which is a ubiquitous intracellular messenger during and immediately after an ischemic period. Disruption in normal calcium hemostasis is known to be a major initiator and activator of the ischemic cell death pathway. Under Ischemic stroke conditions, glutamate is released from the neurons and glia which further activates the N-methyl-D-aspartate (NMDA) receptor and triggers the rapid translocation of Ca2+ from extracellular to intracellular spaces in cerebral tissues and vice versa. Various studies indicated that Ca2+ could have harmful effects on neurons under acute ischemic conditions. Mitochondrial dysfunction also contributes to delayed neuronal death, and it was established decades ago that massive calcium accumulation triggers mitochondrial damage. Elevated Ca2+ levels cause mitochondria to swell and release their contents. As a result oxidative stress and mitochondrial calcium accumulation activate mitochondrial permeability transition and lead to depolarization-coupled production of reactive oxygen species. This association between calcium levels and mitochondrial death suggests that elevated calcium levels might have a role in the neurological outcome in ischemic stroke. Previous studies have also reported that elevated Ca2+ levels play a role in the determination of infarct size, outcome, and recurrence of ischemic stroke. The current review has been compiled to understand the multidimensional role of altered Ca2+ levels in the initiation and alteration of neuronal death after ischemic attack. The underlying mechanisms understood till date have also been discussed.The article has been withdrawn at the request of the co-authors due to the death of the corresponding author (Dr. Aliev).

Cancer immunotherapy has revolutionized cancer treatment in recent years. In particular, Immune Checkpoint Inhibitors (ICIs) as new therapeutic tools have demonstrated encouraging antitumor activity and manageable tolerability in HCC. Immunologic checkpoint blockade with antibodies targeting Programmed cell Death-1 (PD-1), Programmed cell Death Ligand-1 (PD-L1), and Cytotoxic T Lymphocyte-Associated protein-4 (CTLA-4) strengthens tumor immunity by restoring exhausted T cells. Although the efficacy of combination treatment strategies using ICIs combined with other ICIs, molecular targeted agents, systemic therapy, or locoregional therapy has been well documented in numerous preclinical and clinical studies on several types of cancers, most HCC patients do not benefit from ICI treatment. This review highlights recent developments and potential opportunities related to ICIs and their combination in the management of HCC. The present article also includes recent patent review coverage on this topic.
Accumulation of toxic strands of amyloid beta (AB), which cause neurofibrillary tangles and, ultimately, cell death, is suspected to be the main culprit behind clinical symptoms of Alzheimer's disease. Although the mechanism of cell death due to AB accumulation is well known, the intermediate phase between the start of accumulation and cell death is less known and investigated, partially due to technical challenges in identifying partially affected cells.

First, we aimed to establish an in vitro model that would show resilience against AB toxicity. Resiquimod in vitro Then we used morphological, molecular and electrophysiological assays to investigate how the characteristics of the surviving cells changed after AB toxicity.

To investigate this phase, we used differentiation of SH-SY5Y neuroblastoma stem cells by Retinoic Acid (RA) and Brain Derived Neurotrophic Factor (BDNF) to establish an in vitro model which would be able to demonstrate various levels of resistance to AB toxicity. We utilized fluorescent microscopy and whole cell patch clamp recordings to investigate behavior of the model.

We observed significantly higher morphological resilience against AB toxicity in cells which were differentiated by both Retinoic Acid and Brain Derived Neurotrophic Factor compared to Retinoic Acid only. However, the electrophysiological properties of the Retinoic Acid + Brain-Derived Neurotrophic Factor differentiated cells were significantly altered after AB treatment.

We established a transient survival model for AB toxicity and observed the effects of AB on transmembrane currents of differentiated neurons.
