... Different studies indicated that pineal gland calcification was significantly associated with age, sex, low altitude, low sunlight exposure, ethnicity, light, cell phone, fluoride intake, nutrition, and neurodegenerative diseases [7]. A modern lifestyle like using electromagnetic field (EMF)-emitting material such as cell phones and audio/video players; using fluoride in mouthwash, toothpaste, and tab water; and using herbicides were also considered as the critical risk factors for pineal gland calcification [12,28,29]. The prevalence of pineal gland calcification was highest in older age individuals compared with those of young and also highest among obese. ...
... In this study, there is a high prevalence of pineal gland calcification detected by CT scan and most studies showed that males have a high prevalence of pineal gland calicifcation [2][3][4][5][6][7]. Even though there is no clear justification for this variation of pineal gland calcification by sex of individuals, many other studies link such differences to the effect of melatonin on gonadotropins [28][29][30]. As a limitation, most of the studies lack clinical and laboratory data on the function of the pineal gland, making it difficult to extrapolate these findings to neurodegenerative changes in a clinically relevant way. ...
Background
Pineal gland calcification is the formation of corpora arenacea predominantly composed of calcium and phosphorus. It plays an important role in regulating the light/dark circadian changes to synchronize their daily physiological activities like feeding, metabolism, reproduction, and sleep through the secretion of melatonin. Therefore, this study aimed to assess the pooled prevalence of pineal gland calcification.
Methods
A systematic review was done using published research articles from different electronic databases. Cross-sectional studies were included for systematic review and only studies conducted on the human population were included for quantitative analysis. Published articles were selected by assessing the title and abstract for relevance to the review objectives. Finally, the full text was retrieved for further assessment.
Results
The pooled prevalence of pineal gland calcification was 61.65% [95% CI: 52.81, 70.49], with a heterogeneity of I² = 97.7%, P ≤ 0.001. According to the qualitative analysis, an increase in age, male sex, and white ethnicity are the major socio-demographic characteristics that increase the prevalence of pineal gland calcification.
Conclusion
The pooled prevalence of pineal gland calcification was higher compared with reports from previous studies. Different studies reported pineal gland calcification was most prevalent in the adult population compared with the pediatric age groups. According to the qualitative analysis, an increase in age, male sex, and white ethnicity are the major socio-demographic characteristics that increase the prevalence of pineal gland calcification.

Based on the impacts on human health as early as the 90s of the last century, investigations of research centers of excellence in the northern hemisphere has proved the highly harmful effects on human health of the herbicide 2-4D used in the Vietnam War, particularly its carcinogenic effect, the damage to the nervous system, and deformations in descendants of the population exposed to its use (Fogel, 2001). In recent years, new research has focused on the growing neurological damage caused by agrochemicals and particularly on the effects of glyphosate on prenatal health (Bellinger et al, 2016;Falnoga et al., 2000;Mesnage et al., 2013;Mesnage et al., 2014;Nevison, 2014;Seneff et al., 2015;Seralini et al., 2014;Swanson et al., 2014). ...

Según un informe de Monsanto, Paraguay es el país más transgénico considerando la superficie cultivada con OGM. Esto supone un desarrollo notable de las fuerzas productivas que alteran profundamente las relaciones de producción con la aparición de nuevos actores y la desaparición de otros. El desarrollo de nuevas tecnologías también tiene consecuencias en la salud humana, en la intensa contaminación ambiental y en la deforestación de ecosistemas frágiles. En lo que va de este siglo, las grandes corporaciones biotecnológicas que promueven el régimen agroalimentario globalizado emplean tecnologías adecuadas para los cultivos transgénicos, siendo el RR más emblemático del Monsanto que requiere una economía de escala asociada con la concentración de la tierra y su acumulación y utiliza pesticidas en cantidades crecientes, una característica que lo hace autodestructivo como una nueva forma de acumulación. Mientras que los actores dominantes se convierten en representantes de grandes corporaciones, los empresarios brasileños de agronegocios, basados en la soja, dependen de quienes controlan la tecnología y los mercados. La reestructuración agraria también implica la instalación y operación de grandes corporaciones brasileñas que controlan la industria de la carne.

This work thematizes the problem of socio-sanitary and environmental consequences of the vicious circle that links human rights violations, food insecurity, and institutionalized intoxication, mainly in relation to the effects on mental health resulting from environmental contaminants and pesticides. The predatory model of post-industrial capitalism was born linked to central factors, such as: chemical-dependent agriculture, social medicalization, and nutritional transition, associated with the perverse commodification of natural resources. The expansion of large-scale monocultures using pesticides and other environmental contaminants, the expansion of the pharmaceutical industry and medical technology, and the expansion of the industrial additivated food model are consequences associated with these interconnected factors. In addition, this process is stimulated and reproduced in an institutionalized and legalized way and has been producing multiple human rights violations and the deepening of various forms of intoxication and illness: this model can be called the ‘paradigm of the chemicalization of life’.

... Otherwise, a low-quality ecological study that linked U.S. national-level data on glyphosate agricultural applications and various neurological outcomes, including hospital discharge rates, mortality rates, and childhood autism case counts, was identified but not considered further in our weight-of-evidence analysis due to its ecological design and other methodological weaknesses (Seneff et al. 2015) ( Table 2 and Supplemental Table 1). ...
... Ever vs. never use is an extremely limited classification of exposure that obscures a wide range of potential usage scenarios and cumulative doses. Adding the latter seven studies using ever vs. never exposure classification to the six studies with residential proximity-based or ecological exposure metrics (Caballero et al. 2018;Nevison 2014;Rull et al. 2006;Seneff et al. 2015;von Ehrenstein et al. 2019;Yang et al. 2014) and two other low-quality studies that assessed ever vs. never glyphosate use (Garry et al. 2002;Wechsler et al. 1991), three quarters of the available epidemiological studies of glyphosate and neurological outcomes (17 of 23, 74%) offer little to no information on the extent of any individual person's exposure frequency or likely dose of glyphosate. ...
Purpose
Human health risk assessments of glyphosate have focused on animal toxicology data for determining neurotoxic potential. Human epidemiological studies have not yet been systematically reviewed for glyphosate neurotoxicity hazard identification. The objective of this systematic literature review was to summarize the available epidemiology of glyphosate exposure and neurological outcomes in humans.
Methods
As of December 2021, 25 eligible epidemiological studies of glyphosate exposure and neurological endpoints were identified and assessed for five quality dimensions using guidance from the U.S. Environmental Protection Agency. Studies that assessed personal use of glyphosate were prioritized, whereas those assessing indirect exposure (other than personal use) were rated as low quality, since biomonitoring data indicate that indirect metrics of glyphosate exposure almost always equate to non-detectable glyphosate doses.
Results
Overall, the scientific evidence on glyphosate and neurotoxicity in humans is sparse and methodologically limited, based on nine included epidemiological studies of neurodegenerative outcomes (two high quality), five studies of neurobehavioral outcomes (two high quality), six studies of neurodevelopmental outcomes (none high quality), and five studies of other and mixed neurological outcomes (one high quality). The five high-quality studies showed no association between glyphosate use and risk of depression, Parkinson disease, or peripheral nerve conduction velocity. Results were mixed among the eight moderate-quality studies, which did not demonstrate consistent associations with any neurological endpoints or categories. Low-quality studies were considered uninformative about possible neurotoxic effects due primarily to questionable assessments of indirect exposure.
Conclusions
No association has been demonstrated between glyphosate and any neurological outcomes in humans. To move the state of science forward, epidemiological studies should focus on scenarios involving direct and frequent use of glyphosate while collecting information on validated health outcomes, concomitant agricultural exposures, and relevant personal characteristics.
... Since none of the variables of interest can be definitively ruled out as a potential causative factor in an eventual ASD outcome, they must be considered as additive -or even multiplicative as the toxicology shows (Haley, 2005;N. Z. Miller & Goldman, 2011;Seneff et al., 2015;Kennedy et al., 2016) -increasing risk of adverse vaccination outcomes leading to autism and/or related neurological disorders such as Attention Deficit Hyperactivity Disorder (ADHD The authors' use of Inverse Probability of Treatment Weighting Adjustment can only lead to an introduction of error falsely named to imply some kind of "correction". The only error being committed is to regard a known toxicant as if it were a negligible placebo or something of that sort. ...
We report flaws and inconsistencies in a critically important study of autism risk following maternal Tdap vaccination. The authors of the 2018 study, Prenatal Tetanus, Diphtheria, Acellular Pertussis Vaccination and Autism Spectrum Disorder (BC18), concluded that Tdap gestational vaccination is not associated with increased autism risk and claimed to provide “evidence supporting the ACIP’s recommendation to vaccinate pregnant women”. Our observations, based on information from the study itself, challenge these conclusions. We find evidence of a peculiar study design and approach to data analysis forcing outcomes by arbitrary data adjustments, overlooked variables of importance such as Bordetella pertussis infection prevalence and vaccine injury rates, insufficient consideration of likely interactions between multiple historical medical challenges by vaccines and other interventions on their participants, exclusion from the study individuals likely at risk of vaccine intolerance due to genetics, and indications that the study samples were not representative of the general population. Their first-year data show a concerning spike in ASD rates, and their findings and conclusions did not hold up to real-world data, which currently reports 3.8% ASD rate in California. Our observations, based on information from the study itself, challenge the conclusions of Becerra-Culqui et al, 2018.
... In keeping with this, early postnatal pesti-cide exposure has been demonstrated to influence brain development, and a growing body of research suggests that early pesticide exposure has neurobehavioral implications (Heyer and Meredith, 2017). Furthermore, an epidemiological survey found a direct association between the increased use of agricultural chemicals and the prevalence of multiple neurological illnesses at various ages, including autism, dementia, and anxiety disorder (Seneff and Li, 2015). Biochemical markers that might express energy distribution characteristics or be linked to other individual endpoints, such as breeding or development and population health viability, can assist investigators in better understanding the processes associated with environmental stressor exposure (Sokolova et al., 2012). ...
Pesticides, for example, are thought to be essential drivers of brain injury and dysfunction. Abamectin (ABA) is by far the most routinely used pesticide in farming and healthcare, and its toxicity to nontarget organisms has attracted considerable interest. The effect of abamectin pesticide delivered at the postnatal period on the antioxidant defense system was assessed. This study also examined apoptotic gene expression indicators in the brains of rat pups over neonatal weeks. Pregnant Wister rats were split into two groups: G1 received deionized water (control), and G2 received 0.211 mg/L of abamectin. The first day of abamectin exposure was the first day after delivery and continued until the tenth day of lactation. After 10 days (mid lactation) and the lactation period, rat pup brain samples were taken for oxidative biochemistry investigations and apoptotic gene expression (RT–qPCR). In comparison to the control group G1, Abamectin reinforces protein carbonyl levels and glutathione-based enzymes (transferase and peroxidase), whereas superoxide dismutase and glutathione levels are reduced in the pup's brain. Furthermore, Abamectin induced considerable upregulation of proapoptotic (Bax) and antiapoptotic (Bcl-2) mRNA gene expression. Overall, our findings characterize the relationship between brain changes and abamectin administration during lactation periods, even at low doses that are considered safe, and indicate that this abamectin insecticide is harmful to the growing neurological system.

... Of the 104 total journal articles reviewed here, 57 investigated the relationship between pesticide exposures in agricultural work and known areas of the brain. Of the 57 articles concerning pesticide exposure, 20 considered all pesticides without mentioning subcategories, nine focused on insecticides [96,98,100,104,105,109,113,116,149], six focused on organophosphate pesticides [92,93,95,103,112,117,123,139], three focused on herbicides [111,133,136], and the rest focused on either a specific pesticide (e.g., cypermethrin) [134], or a type of pesticide defined by the type of agriculture where it's used (e.g., pesticides used on vineyards) [137]. Because some reviews exist on certain specific types of pesticides, we included all chemicals used to eliminate insects, fungi, and unwanted plants in our definition of pesticides and do not separate them into subgroups below [24,27,42,150,151]. ...
Certain exposures related to agricultural work have been associated with neurological disorders. To date, few studies have included brain health measurements to link specific risk factors with possible neural mechanisms. Moreover, a synthesis of agricultural risk factors associated with poorer brain health outcomes is missing. In this systematic review, we identified 106 articles using keywords related to agriculture, occupational exposure, and the brain. We identified seven major risk factors: non-specific factors that are associated with agricultural work itself, toluene, pesticides, heavy metal or dust exposure, work with farm animals, and nicotine exposure from plants. Of these, pesticides are the most highly studied. The majority of qualifying studies were epidemiological studies. Nigral striatal regions were the most well studied brain area impacted. Of the three human neuroimaging studies we found, two focused on functional networks and the third focused on gray matter. We identified two major directions for future studies that will help inform preventative strategies for brain health in vulnerable agricultural workers: (1) the effects of moderators such as type of work, sex, migrant status, race, and age; and (2) more comprehensive brain imaging studies, both observational and experimental, involving several imaging techniques.
... Melatonin is a methoxyindole hormone. Roundup disrupts pineal function and reduces melatonin production (99). Melatonin (10 mg/kg b.w.) administration with Roundup (500 mg/kg b.w.) for 7 days improved reproductive parameters, reduced lesions at the implantation site, reduced serum TBARS and GSH levels, and corrected oxidative damage in female Wistar rats that was induced by GLYP (42). ...
Glyphosate (GLYP) is a widely used pesticide; it is considered to be a safe herbicide for animals and humans because it targets 5-enolpyruvylshikimate-3-phosphate synthase. However, there has been increasing evidence that GLYP causes varying degrees of toxicity. Moreover, oxidative stress and metabolism are highly correlated with toxicity. This review provides a comprehensive introduction to the toxicity of GLYP and, for the first time, systematically summarizes the toxicity mechanism of GLYP from the perspective of oxidative stress, including GLYP-mediated oxidative damage, changes in antioxidant status, altered signaling pathways, and the regulation of oxidative stress by exogenous substances. In addition, the metabolism of GLYP is discussed, including metabolites,metabolic pathways, metabolic enzymes, and the toxicity of metabolites. This review provides new ideas for the toxicity mechanism of GLYP and proposes effective strategies for reducing its toxicity.
... Chronic exposure to glyphosate is however noxious and commonly associated with a plethora of human pathologies including epithelial (Samsel and Seneff, 2013;Seneff et al., 2015), neural (Mesnage et al., 2015(Mesnage et al., , 2017Thongprakaisang et al., 2013), cardiocirculatory and muscular disorders (Manas et al., 2009;Sritana et al., 2018;Thongprakaisang et al., 2013), neoplasia, and teratogenic effects (Hokanson et al., 2007;Koller et al., 2012;Kwiatkowska et al., 2017;Richard et al., 2005;Wozniak et al., 2018). According to some studies (Gasnier et al., 2009;Hokanson et al., 2007;Richard et al., 2005) GLY concentrations one hundred times lower than those used in agricultural practices can interact with estrogenic and androgenic receptors on the surface of cells (Cattani et al., 2014;Li et al., 2013b;Parajuli et al., 2015) and behave as a competitive aromatase inhibitor (Hokanson et al., 2007;Richard et al., 2005;Wozniak et al., 2018). ...
... The inhibitory effect as referred for aromatase extends to other cytochrome P450 isozymes constituting the Phase I detoxification pathway in mammals. As a consequence, there is an increment in foodborne chemical residues and other xenobiotics (Seneff et al., 2015). On the other hand, it has been observed that GLY-DNA interaction results in the oxidation of pyrimidines that can induce teratogenic and carcinogenic effects (Koller et al., 2012;Kwiatkowska et al., 2017;Manas et al., 2009;Wozniak et al., 2018). ...
Glyphosate (GLY) is the main ingredient in the weed killer Roundup and the most widely used pesticide in the world. Studies of the harmful effects of GLY on human health began to become more wide-ranging after 2015. GLY is listed by the International Agency for Research on Cancer (IARC) as a carcinogenic hazard to humans. Moreover, GLY has the property to complex with transition metals and are stable for long periods, being considered a high-risk element for different matrices, such as environmental (soil and water) and food (usually genetically modified crops). Since that, it was noticed an increment in the development of new analytical methods for its determination in different matrices like food, environmental and biological fluids. Noteworthy, the application of electrochemical techniques for downstream detection sparked interest due to the ability to minimize or eliminate the use of polluting chemicals, using simple and affordable equipment.
This work aims to review the contribution of the electroanalytical methods for the determination of GLY in different food and environmental matrices. Parameters such as the electrochemical transduction techniques based on the electrical measurement signals, receptor materials for electrodes preparation, and the detection mechanisms are described in this review. The literature review shows that the electrochemical sensors are powerful detection system that can be improved by their design and by their portability to fulfil the needs of the GLY determination in laboratory benches, or even in situ analysis.
