background botulism is a toxin-induced paralytic illness characterized by cranial nerve palsies and descending flaccid paralysis. botulinum toxin is regarded as the most lethal ever-known substance. the diagnosis in sporadic cases and even in small outbreaks is the main physicians’ challenge. the aim of this study was to assess clinical presentations of 80 cases of botulism referred to loghman ...

Alternaria brown spot disease is caused by the alternata tangerine pathotype, which relies on ACT-toxin for infection. At present, all identified biosynthesis-related genes are multi-copy genes. In this study, we summarized advances in important host-specific toxins (HSTs), and listed key required pathogenicity of A. pathotype. Toxin virulence test results revealed that different citrus species...

brown spot disease caused by alternaria alternata (fr.: fr.) keissl is a serious problem forproduction of tangerines and tangerine hybrids in iran. the tangerine pathotype causes brownspot disease on young leaves and immature fruits of limited varieties of mandarins and tangerines(citrus. reticulata blanco). specificity in the interaction between tangerine and the pathogen isdetermined by a hos...

Background: Considering the severe health and environmental hazards caused by the entry of diazinon toxin into water resources, its removal is very important. Given the high costs of imported adsorbents, this research attempted to evaluate, for the first time, the efficiency of Iranian activated carbon in removing diazinon from aqueous solutions. Methods: In this batch experimental study, the ...

I am the Paul E. Holden Professor of Management Science at the Graduate School of Business, Stanford University. Since September 11, 2001, I have used mathematics to analyze a variety of homeland security problems in bioterrorism (effective responses to terrorist attacks using smallpox, anthrax or botulinum toxin) and in border security (identifying ways to improve the biometric aspects of the ...

Thrice weekly in-center hemodialysis is the standard of care for dialysis patients with end-stage renal disease (ESRD). However, there is ongoing debate as to whether more frequent hemodialysis, with its readier management of both toxin and fluid removal, benefits patients. New evidence from recent studies, both in center dialysis and in home haemodialysis patients, adds further confirmation of...

Methods Electronic medical records of patients requiring CRRT during their stay in our 35-bed medical-surgical ICU (January 2012-December 2013) were reviewed. Patients were excluded if they were dialysis-dependent prior to admission, started on CRRT for toxin removal only, transferred to another hospital while on CRRT or died within 24 hours of admission. Binary logistic regression was performe...

OBJECTIVE To evaluate and permanently improve axillary hyperhidrosis. BACKGROUND Excessive sweating of the axillae is a common problem for which patients frequently seek dermatologic advice and therapy. Many treatments, including aluminum chloride, topical and systemic anticholinergic agents, tranquilizers, iontophoresis, direct surgical excision, botulinum toxin injection, and thoracic sympa...

certain strains of staphylococcus aureus produce a toxin which cause epidermal exfoliation within 18 hours after direct subcutaneous or intraperitoneal injection into newborn mice. the extracellular product responsible for exfoliation is termed exfoliative toxin (et). in the present studies a modified assay system has been developed for detection of exfoliativeactivity in toxin negative strains...
