They are used in many modern-day applications, in agriculture, medicine, and industry. Heavy metal poisoning occurs when body's soft tissues absorb too much of a particular metal. The heavy metals of interest for this review paper were cadmium, arsenic, mercury and lead, since these are the most common metals that the human body can absorb in toxic amounts. Different plant species were investigated in recent years for their effect on oxidative stress parameters after intoxication with heavy metals. OBJECTIVES This review paper is focused on current update to research on heavy metals induced oxidative stress in animal models and improvement of the oxidative stress parameters upon/co-/after treatment with different plant extracts and isolated compounds. RESULTS Various parameters of oxidative stress were investigated and their improvement with plant extracts/compounds was noticed in the brain, lungs, kidneys, liver, uterus, testis, thymus, spleen, heart, skin and blood of experimental animals. Common parameters used to determine oxidative stress in animals were superoxide dismutase; catalase; reduced glutathione; glutathione reductase; glutathione-S-transferase; glutathione peroxidase; lipid peroxidation; oxidized glutathione; malondialdehyde; xanthine oxidase; nonprotein-soluble thiol; thioredoxin reductase; total sulphydryl group; nitric oxide; γ-glutamyl cysteine synthetase. CONCLUSIONS The most investigated species for antioxidant effects upon intoxication with heavy metals seem to be Allium sp., Bacopa monniera, Camellia sinensis, Moringa oleifera, Vitis vinifera and Zingiber officinale. According to literature data, the most promising effect to alleviate symptoms of intoxication was achieved with proanthocyanidins obtained from Vitis vinifera.

AD influences the part of the brain that controls cognitive and noncognitive functions. OBJECTIVE The study focuses on the screening of natural compounds for the inhibition of AChE and BuChE using a computational methodology. METHODS We performed a docking-based virtual screening utilizing the 3D structure of AChE and BuChE to search for potential inhibitors for AD. Selleckchem SBI-0206965 In this work, a screened inhibitor Ajmalicine similarity search was carried out against a natural products database (Super Natural II). Lipinski rule of five was carried out and docking studies were performed between ligands and enzyme using 'Autodock4.2'. RESULTS Two phytochemical compounds SN00288228 and SN00226692 were predicted for the inhibition of AChE and BuChE, respectively. The docking results revealed Ajmalicine, a prominent natural alkaloid, showing promising inhibitory potential against AChE and BuChE with the binding energy of - 9.02 and -8.89 kcal/mole respectively. However, SN00288228- AChE, and SN00226692-BuChE were found to have binding energy -9.88 and -9.54 kcal/mole, respectively. These selected phytochemical compounds showed better interactions in comparison to Ajmalicine with the target molecule. CONCLUSION The current study verifies that SN00288228 and SN00226692 are more capable inhibitors of human AChE and BuChE as compared to Ajmalicine with reference to ΔG values.

Ablation of the arrhythmia has emerged as a putative means of disrupting its natural course by isolating its triggers and modifying its substrate, dependent on the chosen method. An important dilemma lies in the need for continuation of anticoagulation therapy in those previously receiving it following an, apparently, successful intervention, purportedly preventing arrhythmia recurrence with considerably high rates. Current guidance, given scarcity of high-quality data from randomized trials, focuses on established knowledge and recommends anticoagulation continuation based solely on estimated thromboembolic risk. In the present review it will be attempted to summarize the pathophysiological rationale for maintaining anticoagulation post-successful ablation, along with the latter's definition, including the twofold effects of the procedure per se on thrombogenicity. Available evidence pointing to an overall clinical benefit of anticoagulation withdrawal following careful patient assessment will be discussed, including ongoing randomized trials aiming to offer definitive answers. Finally, the proposed mode of post-ablation anticoagulation will be presented, including the emerging, guideline-endorsed, role of direct oral anticoagulants in the field, altering cost/benefit ratio of anticoagulation and potentially affecting the very decision regarding its discontinuation.

Secondary prevention, in particular in the acute phase of stroke with anti-thrombotic therapy has not been validated. The aim of this review is to evaluate the available evidence on the use of antithrombotic therapy in patients with recent stroke who have AF, and suggest a treatment algorithm for the various time points, taking into account both the bleeding and thrombosis risks posed at each stage.

The UPR mechanism is highly conserved in fungi, higher organisms, plants and mammals. The UPR pathway is activated to stabilize ER functions when there are too many unfolded proteins or misfolded proteins in the ER. However, stress continues when ER proteins are stimulated by toxic substances that affect the balance of the UPR pathway, which causes changes in the structure and function of the ER and other organelles. These ultimately disrupt homeostasis in the body and cause pathological reactions that can be fatal. The UPR mechanism has clear effects on stabilizing the protein-folding environment. Dysfunction or disruption of the UPR mechanism is associated with numerous disorders, including neurodegenerative diseases, loss of control of protein secretion, cerebral ischemia and epilepsy, neuropsychiatric diseases, eye diseases, skin diseases, metabolic and inflammatory diseases, atherosclerosis, and heart disease.
