Stroke is a serious condition often resulting in mortality or long-term disability, causing cognitive, memory, and motor impairments. A reduction in cerebral blood flow below critical levels defines the ischemic core and penumbra: the core undergoes irreversible damage, while the penumbra remains viable but functionally impaired. This functional impairment activates complex cell signaling pathways that determine cell survival or death, making the penumbra a key target for therapeutic interventions to prevent further damage.

Article Synopsis
  • The study investigates the long-term health effects on infants born to mothers with COVID-19, focusing on those with congenital gastrointestinal malformations (CGIMs) who required surgery.
  • A total of 41 patients were analyzed, divided into two groups based on their mothers' COVID-19 status, and a one-year follow-up assessed their growth and developmental milestones.
  • Results showed that infants from COVID-19-positive pregnancies (Group 1) had significantly lower height and weight than those from non-COVID-19 pregnancies (Group 2), with a notable prevalence of antibiotic use and malabsorption syndrome in Group 1.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by beta-amyloid (Aβ) deposition and increased acetylcholinesterase (AchE) enzyme activities. Indole 3 carbinol (I3C) and diindolylmethane (DIM) are reported to have neuroprotective activities against various neurological diseases, including ischemic stroke, Parkinson's disease, neonatal asphyxia, depression, stress, neuroinflammation, and excitotoxicity, except for AD. In the present study, we have investigated the anti-AD effects of I3C and DIM.

Global cerebral ischemia is one of the major causes of memory and cognitive impairment. Hyperactivation of acetylcholine esterase (AChE), oxidative stress, and inflammation are reported to cause memory and cognitive impairment in global cerebral ischemia. Morin, a flavonoid, is reported to have neuroprotective properties through its antioxidant and anti-inflammatory in multiple neurological diseases.

Ischemic stroke is a devastating disease that causes morbidity and mortality. Malnutrition following ischemic stroke is common in stroke patients. During the rehabilitation, the death rates of stroke patients are significantly increased due to malnutrition.

Neurological disorders incidences are increasing drastically due to complex pathophysiology, and the nonavailability of disease-modifying agents. Several attempts have been made to identify new potential chemicals to combat these neurological abnormalities. At present, complete abolishment of neurological diseases is not attainable except for symptomatic relief.

Global cerebral ischemia is commonly associated with neurological deficits, including cognitive and memory impairments. The present study aims to investigate the neuroprotective, cognitive, and memory enhancement effects of Tangeretin, a flavonoid against global cerebral ischemia in rats. Bilateral common carotid artery occlusion (BCCAO) and reperfusion injury method was used to induce global cerebral ischemia in rats.

Alzheimer's disease (AD) is a progressive brain disorder associated with slow loss of brain functions leading to memory failure and modest changes in behavior. The multifactorial neuropathological condition is due to a depletion of cholinergic neurons and accumulation of amyloid-beta (Aβ) plaques. Recently, a multi-target-directed ligand (MTDL) strategy has emerged as a robust drug discovery tool to overcome current challenges.

Wnt/β-catenin (WβC) signaling pathway is an important signaling pathway for the maintenance of cellular homeostasis from the embryonic developmental stages to adulthood. The canonical pathway of WβC signaling is essential for neurogenesis, cell proliferation, and neurogenesis, whereas the noncanonical pathway (WNT/Ca and WNT/PCP) is responsible for cell polarity, calcium maintenance, and cell migration. Abnormal regulation of WβC signaling is involved in the pathogenesis of several neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and spinal muscular atrophy (SMA).

Indole-3-carbinol (I3C) is reported to have hepatic and neuroprotective properties. However, the I3C role in the protection of the liver and brain in the pathological condition of hepatic encephalopathy has not been investigated. Therefore, in the present study, we have assessed the hepatic and neuroprotective roles of I3C against thioacetamide (TAA)- induced hepatic encephalopathy in Wistar rats.

Introduction: Diindolylmethane (DIM), a major acid condensation product of Indole-3- carbinol, is known to inhibit platelet aggregation and thrombosis. The drugs with antiplatelet and antithrombotic activities are used to treat ischemic stroke.

Objective: The present study investigated the role of DIM on platelet aggregation inhibitory properties in middle cerebral artery occluded (MCAO) rats.

Neonatal anoxia is linked to long-lasting neurodevelopmental deficits. Due to the lack of pharmacological intervention to treat neonatal anoxia, there is interest in finding new molecules for its treatment. Indole-3-carbinol (I3C) has shown neuroprotective effects in some disease conditions.

Background And Objectives: Indole-3-carbinol (I3C) is reported to have neuroprotective properties in an animal model of ischemic stroke. However, the pharmacokinetics of I3C in stroke animals are unknown. Furthermore, the most effective method of I3C delivery for the treatment of stroke has yet to be determined.

The present study investigated the cardioprotection of Indole-3-carbinol on isoproterenol (ISO)-induced myocardial infarction in Wistar rats. I3C treatment significantly reduced the prolongation of the QRS complex, QT interval, and ST-segment elevation. I3C was also able to normalise blood pressure (SBP, DBP, and MAP) and HR.

Diindolylmethane (DIM), a major metabolite of indole-3-carbinol (I3C), plays a vital role in the pharmacological actions of I3C. The role of DIM in the inhibition of platelet aggregation and thrombus generation is yet to be revealed. However, how DIM and I3C modulate the interaction of platelets with the glycoproteinVI (GPVI) and purinergic receptor Y (PY) receptors is unknown.

Alzheimer's disease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-target directed ligand (MTDL) strategy has been evolved as an auspicious approach for the treatment of AD.
