Abstract

Background: Cellphone radiation (CR) has been reported to be related to higher risk of many health problems, but if CR can impair sexual behavior and testosterone synthesis has seldom been studied. Objective: To evaluate the effects of CR on testosterone and luteinizing hormone (LH) levels and sexual behaviors of male mice. Methods: Forty 3-month-old male mice, 22 – 25 g, were randomly allocated into four equal groups (n = 10 per group): the control group and three CR exposure groups including 8-hour group, 16-hour group and 24-hour group. Each mouse received different dose of CR exposure for 30 consecutive days. Sexual behaviors and testosterone and LH levels in serum were measured at the end of experiment. Furthermore, we also observed the weights of reproductive organs of each group, including testis, epididymis and seminal vesicle. Results: The mount latency and intromission latency in 24-hour group were significant higher than the control (both P < 0.01), while no obvious changes were seen in 8-hour group and 16-hour group (all P > 0.05). No difference in ejaculation latency existed among each group after the experiment (all P > 0.05). The frequency of mount and intromission in 24-hour group was statistically significantly lower than that of the control group (P < 0.05 and P < 0.01, respectively). No obvious change in the frequency of mount and intromission of the 8-hour group and 16-hour group was seen (all P > 0.05). Only the copulatory efficacy in the 24-hour group was statistically lower than the control group (P < 0.05). The serum levels of testosterone and LH in the 24-hour group were obviously higher than the control group (testosterone level: P < 0.05; LH level: P < 0.01). No significant differences were seen among the other two experimental groups and the control group (all P > 0.05). After the exposure of CR, the changes in the weights of sexual organs in the 24-hour group were significant compared with the control (testis weights, relative testis weight, epididymis weight, the weight of seminal vesicle, and the relative weight of seminal vesicle, all P < 0.01; the relative epididymis weight, P < 0.05). Conclusions: High dose exposure of CR can decline the testosterone and LH levels in mice and inhibit their sexual behaviors.

Highlights

7 effects have each been repeatedly reported following Wi-Fi & other EMF exposures.•

Established Wi-Fi effects, include apoptosis, oxidat. stress &:•

testis/sperm dysfunct; Neuropsych; DNA impact; hormone change; Ca2+ rise.•

Wi-Fi is thought to act via voltage-gated calcium channel activation.•

One claim of no Wi-Fi effects was found to be deeply flawed.

Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. Each of these effects are also caused by exposures to other microwave frequency EMFs, with each such effect being documented in from 10 to 16 reviews. Therefore, each of these seven EMF effects are established effects of Wi-Fi and of other microwave frequency EMFs. Each of these seven is also produced by downstream effects of the main action of such EMFs, voltage-gated calcium channel (VGCC) activation. While VGCC activation via EMF interaction with the VGCC voltage sensor seems to be the predominant mechanism of action of EMFs, other mechanisms appear to have minor roles. Minor roles include activation of other voltage-gated ion channels, calcium cyclotron resonance and the geomagnetic magnetoreception mechanism. Five properties of non-thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults. These general findings and data presented earlier on Wi-Fi effects were used to assess the Foster and Moulder (F&M) review of Wi-Fi. The F&M study claimed that there were seven important studies of Wi-Fi that each showed no effect. However, none of these were Wi-Fi studies, with each differing from genuine Wi-Fi in three distinct ways. F&M could, at most conclude that there was no statistically significant evidence of an effect. The tiny numbers studied in each of these seven F&M-linked studies show that each of them lack power to make any substantive conclusions. In conclusion, there are seven repeatedly found Wi-Fi effects which have also been shown to be caused by other similar EMF exposures. Each of the seven should be considered, therefore, as established effects of Wi-Fi.

Graphene-based edible electronics will let you make cereal circuits

John Biggs@johnbiggs / 11:03 AM GMT-5•March 1, 2018 Researchers at the have successfully etched edible circuits onto the surface of food, paving the way for RFID tagged edibles that can help us track food from farm to tummy. The project, which uses something called laser-induced graphene (LIG), is a process that creates a “foam made out of tiny cross-linked graphene flakes” that can carry electricity through carbon-rich products like bread, potatoes, and cardboard.

“Overall, the process demonstrated that LIG can be burned into paper, cardboard, cloth, coal, potatoes, coconuts, toasted bread and other foods,” wrote the researchers who hail from Rice University’s Smalley-Curl Institute and Ben-Gurion University of the Negev.

The process can embed or burn patterns that could be used as supercapacitors, radio frequency identification (RFID) antennas or biological sensors. Based on these results, the researchers theorized that any substance with a reasonable amount of carbon can be turned into graphene. To test this theory, Tour’s team sought to burn LIG into food, cardboard and several other everyday, carbon-based materials.

Presumably you won’t be etching power sources and other components onto your Pop Tarts but this early research into edible circuits could pave the way for smarter food.

Particle and Fibre Toxicology volume 13, Article number: 57 (2016) Due to their unique physicochemical properties, graphene-family nanomaterials (GFNs) are widely used in many fields, especially in biomedical applications. Currently, many studies have investigated the biocompatibility and toxicity of GFNs in vivo and in intro. Generally, GFNs may exert different degrees of toxicity in animals or cell models by following with different administration routes and penetrating through physiological barriers, subsequently being distributed in tissues or located in cells, eventually being excreted out of the bodies. This review collects studies on the toxic effects of GFNs in several organs and cell models. We also point out that various factors determine the toxicity of GFNs including the lateral size, surface structure, functionalization, charge, impurities, aggregations, and corona effect ect. In addition, several typical mechanisms underlying GFN toxicity have been revealed, for instance, physical destruction, oxidative stress, DNA damage, inflammatory response, apoptosis, autophagy, and necrosis. In these mechanisms, (toll-like receptors-) TLR-, transforming growth factor β- (TGF-β-) and tumor necrosis factor-alpha (TNF-α) dependent-pathways are involved in the signalling pathway network, and oxidative stress plays a crucial role in these pathways. In this review, we summarize the available information on regulating factors and the mechanisms of GFNs toxicity, and propose some challenges and suggestions for further investigations of GFNs, with the aim of completing the toxicology mechanisms, and providing suggestions to improve the biological safety of GFNs and facilitate their wide application. Conclusions In the past few years, GFNs have been widely utilized in a wide range of technological and biomedical fields. Currently, most experiments have focused on the toxicity of GFNs in the lungs and livers. Therefore, studies of brain injury or neurotoxicity deserve more attention in the future. Many experiments have shown that GFNs have toxic side effects in many biological applications, but the in-depth study of toxicity mechanisms is urgently needed. In addition, contrasting results regarding the toxicity of GFNs need to be addressed by effective experimental methods and systematic studies. This review provides an overview of the toxicity of GFNs by summarizing the toxicokinetics, toxicity mechanisms and influencing factors and aimed to provide information to facilitate thorough research on the in vitro and in vivo haemo- and biocompatibility of GFNs in the future. This review will help address safety concerns before the clinical and therapeutic applications of GFNs, which will be important for further development of GFNs in biological applications.

Graphene being an allotrope of carbon is considered one of the best products to be produced for industries throughout the world. Its characteristics and properties make it one of a kind and enable the applications in rather a very vast scenario. One such is in the food and beverage packing industry.

Food and beverages are items related to the health and well-being of humans so they need to be cared for cautiously. Graphene plays a major and vast role in maintaining the hygiene of food and beverages and due to this role, food industries are benefiting a lot from graphene.

Abstract

Graphene is found in charred roasted meat and also in plant charcoal, which is present in the infant’s gripe water. Graphene as graphene oxide (GO) is produced on charring the surface of meat on a barbecue forming nitrogen doped GO originating from the pyrolysis of protein in air. The unintentional intake of such nano carbon stained cooked meat is a traditional delicacy. The presence of graphene and nano carbon particles in plant charcoal, used in the branded formulation of gripe water applied for stomach ailments in infants as a medicine, strongly refutes the toxicity of such nano carbons in humans. The isolation of graphene and nano particulates from both the sources is described here. These are characterized by elemental analysis, Raman spectroscopy, PXRD and by FESEM, TEM and SADP image analysis. The intake of nano carbon contaminated roasted food since the discovery of fire possibly trails mutation to evolve resistance in humans. This work suggests that graphene and other nano carbon particles produced by the pyrolysis of bio-products in air are non-toxic to humans.
