toxic optic neuropathy (ton) is a group of medical disorders which can be defined by visual impairment due to optic nerve damage by a toxin. the exposure to a toxic substance can occur at the workplace, with ingestion of materials/ foods containing a toxin, or the use of systemic medications. ton is a disease entity which is not only under-diagnosed, but also often diagnosed at a stage when rec...

conclusions the nps-induced ots may increase the pro-inflammatory responses. on the other hand, administration of antioxidants such as nac and vitamin c and e prior to exposure to metal nps significantly decreases ots conditions. evidence acquisition here, a nanotechnology approach is evaluated using nps in human neuronal protection against ots. it may be wide therapeutic applications in the ca...

Aim: To compare patients with toxic and non-toxic nodular/multinodular goiter in terms of clinical, sonographical cytological features.
 Material Method: The medical data 326 were reviewed retrospectively. Clinical sonographic features examined. Four hundred eighty-one nodules compared sonographically cytologically. One twenty-four had nodular 202 them goiter.
 Results: group was olde...

IMPORTANCE Polycyclic aromatic hydrocarbons are common carcinogenic and neurotoxic urban air pollutants. Toxic exposures, including air pollution, are disproportionately high in communities of color and frequently co-occur with chronic economic deprivation. OBJECTIVES We examined whether the association between child IQ and prenatal exposure to polycyclic aromatic hydrocarbons differed betwee...

Chitosan is a biocompatible material that has been researched in many areas in recent years. As it can be obtained from renewable sources, has antimicrobial properties, is biocompatible, and has no toxic effect, chitosan is currently a widely-used material. The use of chitosan was investigated in different areas related to dentistry. Chitosan is used in the prevention of caries and wear, to inc...

Here, we report the first draft genome sequence (42.38 Mb containing 13,657 genes) of Coniochaeta ligniaria NRRL 30616, an ascomycete with biotechnological relevance in the bioenergy field given its high potential for bioabatement of toxic furanic compounds in plant biomass hydrolysates and its capacity to degrade lignocellulosic material.

While starch and fat digestion can be carried out satisfactorily without the help of pancreatic enzymes, the proteases are critical to proper protein digestion. Incomplete digestion of proteins creates a number of problems for the body including the development of allergies and formation of toxic substances produced during putrefaction. Putrefaction refers to the breakdown of protein material b...

Among them, perfluorooctane sulfonate (PFOS) is speculated to be highly persistent, bioaccumulative and toxic (PBT) compound. Afterwards, PFOS and its synthetic starting material, perfluorooctyl sulfonyl fluoride (PFOSF), have been designated as persistent organic pollutants (POPs) by the Stockholm Convention on POPs in 2009. Therefore, to efficiently reduce PFC pollution, an understanding of P...
