RESEARCH ARTICLE Anti-Glioma Effect of Pseudosynanceia
DOI:10.31557/APJCP.2021.22.7.2295 Effect of Pseudosynanceia Melanostigma Venom on Glioblastoma Cells RESEARCH ARTICLE Editorial Process: Submission:02/14/2021 Acceptance:07/15/2021 Anti-Glioma Effect of Pseudosynanceia Melanostigma Venom on Isolated Mitochondria from Glioblastoma Cells Maral Ramezani, Fatemeh Samiei, Jalal Pourahmad* Abstract Background: Glioblastoma is the most common primary malignant tumor of the central nervous system that occurs in the spinal cord or brain. Pseudosynanceia Melanostigma is a venomous stonefish in the Persian Gulf, which our knowledge about is little. This study’s goal is to investigate the toxicity of stonefish crude venom on mitochondria isolated from U87 cells. Methods: In the first stage, we extracted venom stonefish and then isolated mitochondria have exposed to different concentrations of venom. Finally, mitochondrial toxicity parameters (Succinate dehydrogenase (SDH) activity, Reactive oxygen species (ROS), cytochrome c release, Mitochondrial Membrane Potential (MMP), and mitochondrial swelling) have evaluated. Results: To determine mitochondrial parameters, we used 115, 230, and 460 µg/ml concentrations. The results of our study show that the venom of stonefish selectively increases upstream parameters of apoptosis such as mitochondrial swelling, cytochrome c release, MMP collapse and ROS. Conclusion: This study suggests that Pseudosynanceia Melanostigma crude venom has selectively caused toxicity by increasing active mitochondrial oxygen radicals. This venom could potentially be a candidate for the treatment of glioblastoma.

Gulf Radio: Dancing on the Sealing? Chart Chat
August 16, 2010 Issue 205 Gulf Radio: Dancing On The Sealing? Programmers across the Gulf region weren’t sure what to expect from the big BP spill when Country Aircheck checked in with them 11 weeks ago (Country Aircheck Weekly 6/1). Now, the well has been contained, a final “kill” to seal it is proceeding and the area’s waters are suitable for Presidential swimming. So what do our Gulf radio friends say from the other side of the spill? Beaches, fishing and radio revenues: Not that bad. Perception and tourism: That bad. WKSJ/Mobile PD Bill Black calls it “a summer gone” and says worries remain. “Our fishing industry still suffers, although some waters have Vette Dreams: A few of Brad Paisley’s friends played hooky Monday (8/16) reopened for shrimping and crabbing.

Spider Bites
Infectious Disease Epidemiology Section Office of Public Health, Louisiana Dept of Health & Hospitals 800-256-2748 (24 hr number) www.infectiousdisease.dhh.louisiana.gov SPIDER BITES Revised 6/13/2007 Epidemiology There are over 3,000 species of spiders native to the United States. Due to fragility or inadequate length of fangs, only a limited number of species are capable of inflicting noticeable wounds on human beings, although several small species of spiders are able to bite humans, but with little or no demonstrable effect. The final determination of etiology of 80% of suspected spider bites in the U.S. is, in fact, an alternate diagnosis. Therefore the perceived risk of spider bites far exceeds actual risk. Tick bites, chemical burns, lesions from poison ivy or oak, cutaneous anthrax, diabetic ulcer, erythema migrans from Lyme disease, erythema from Rocky Mountain Spotted Fever, sporotrichosis, Staphylococcus infections, Stephens Johnson syndrome, syphilitic chancre, thromboembolic effects of Leishmaniasis, toxic epidermal necrolyis, shingles, early chicken pox lesions, bites from other arthropods and idiopathic dermal necrosis have all been misdiagnosed as spider bites. Almost all bites from spiders are inflicted by the spider in self defense, when a human inadvertently upsets or invades the spider’s space. Of spiders in the United States capable of biting, only a few are considered dangerous to human beings. Bites from the following species of spiders can result in serious sequelae: Louisiana Office of Public Health – Infectious Disease Epidemiology Section Page 1 of 14 The Brown Recluse: Loxosceles reclusa Photo Courtesy of the Texas Department of State Health Services The most common species associated with medically important spider bites: • Physical characteristics o Length: Approximately 1 inch o Appearance: A violin shaped mark can be visualized on the dorsum (top). -

Stingray Bay: Media Kit
STINGRAY BAY: MEDIA KIT Stingray Bay has been the talk of the town! What is it? Columbus Zoo and Aquarium guests and members will now have the opportunity to see stingrays up close and to touch these majestic creatures! The Stingray Bay experience will encourage visitors to interact with the Zoo’s brand new school of stingrays by watching these beautiful animals “fly” through the water and dipping their hands in the water to come in contact with them. Where is located? Located in Jungle Jack’s Landing near Zoombezi Bay, Stingray Bay will feature an 18,000-gallon saltwater pool for stingrays to call home. Staff and volunteers will monitor the pool, inform guests about the best ways to touch the animals and answer questions when the exhibit opens daily at 10 a.m. What types of stingrays call Stingray Bay home? Dozens of cownose and southern stingrays will glide though the waters of Stingray Bay. Educational interpreters will explain the role of these stingrays in the environment. Stingrays are typically bottom feeders with molar-like teeth used to crush the shells of their prey such as crustaceans, mollusks, and other invertebrates. I’m excited to touch the stingrays, but is it safe? Absolutely! The rays barbs have been carefully trimmed off their whip-like tails. The painless procedure is similar to cutting human fingernails. Safe for all ages, the landscaped pool features a waterfall and a wide ledge for toddlers to lean against when touching the rays. This sounds cool! How much does it cost? Admission to Stingray Bay is free for Columbus Zoo and Aquarium Gold Members and discounted for Members. -

Awareness, Prevention and Treatment of World-Wide Marine Stings and Bites
Awareness, Prevention and Treatment of world-wide marine stings and bites Dr Peter Fenner Honorary Medical Officer, Surf Life Saving Australia International Life Saving Federation Medical/Rescue Conference Proceedings September 1997 Abstract The most common world-wide first aid treatment used by the average lifesaver/lifeguard is the treatment of marine envenomation, especially the treatment of jellyfish stings. It is important to use the correct first aid treatment for each type of envenomation. This study provides a simplified protocol for: - 1. Awareness of the geographical distribution and possibilities of envenomation enabling: - 2. Preventative strategies to reduce morbidity and mortality from marine envenomation 3. First aid treatment of marine envenomation by jellyfish or other marine animals This discussion is based on protocols developed for Surf Life Saving Australia and other first aid providers in Australia over the past ten years. Their success has been proven by a 30% reduction in the number of stings over the past 10 years (statistics from the author’s records). Information for this article has been taken from: - 1. Venomous and poisonous marine animals: a medical and biological handbook produced by Surf Life Saving Queensland 2. The global problem of cnidarian stinging. MD Thesis by the author for the University of London. Introduction The global problem of marine envenomation is not fully appreciated. Each year hundreds of deaths occur from poisoning (by ingestion or eating) or by envenomation (stinging by jellyfish, or biting by venomous marine animals). The morbidity is even greater with jellyfish stings world-wide being numbered in their millions. Each summer it is estimated that up to half a million stings occur on the east coast of the United States from the Portuguese man-o’-war (Physalia physalis). -
