Cannabinoids, Oxidative Stress and Female Reproduction: Where do we stand?

Published on: 6th June, 2025

Cannabis sativum has long been used globally for hallucination. However, detrimental effects on female reproduction have never been studied. The aim of the present paper is to evaluate cannabinoid-induced oxidative stress and reproductive containment in female mice. Fifteen adult female Parkes strain mice were randomly chosen from institutional animal houses (n = 5/group) with ad libitum access to water and food. Animals were grouped into control (vehicle-treated), treated with 6mg of cannabis/100 g of body weight, and 12 mg of cannabis/100 g of body weight. After 15 days all animals were sacrificed and tissues were collected for histology, immunohistochemistry, and estimations of different parameters. Histology and immunohistochemistry (of Cannabinoid Receptor 1; CB1) were performed following standardized protocols. All parameters were estimated either by standard biochemical protocols or by kit following the manufacturer’s protocol. Stress parameters (Super Oxide Dismutase; SOD, Catalase, CAT; Malonaldehyde, MDA and Glutathione Peroxidase; GPx), apoptotic parameters of thecal cells (by Caspase-3 assay), serum level of Estrogen (E2), steroidogenic parameters (3β Hydroxy-steroid dehydrogenase; 3β HSD and 17β Hydroxy-steroid dehydrogenase; 17β HSD) and expression of CB1 were noted in ovary. Data were analyzed by One-way Analysis of Variance (One-way ANOVA) followed by Duncan’s Multiple Range post hoc Test. We found a significant (p < 0.05) decrease in steroidogenic parameters and a significant increase (p < 0.05)in free radical and apoptotic parameters and CB1 receptor expressions upon dose-dependent cannabis treatment. We may conclude that chronic treatment of cannabis causes reproductive containment in females which has never been addressed previously.

Biodegradation of gold and platinum implants in rats studied by electron microscopy

Published on: 27th November, 2019

OCLC Number/Unique Identifier: 8452128684

Graphical abstract Biodegradation of implanted gold in human tissue. TEM images reveal markedly biodegradation of implanted gold and re-crystallization of dissolved gold as nanoparticle of different size, shape and crystallinity. Highly crystalline icosahedral Au nanoparticle and the corresponding power spectrum are shown on top. Background: Despite the importance of biodegradation for the durability of metal prosthesis and the widely use of gold implants, there exist a lack of knowledge regarding the stability of pure gold in tissue. Methods: We studied biodegradation of grids of pure gold, nickel, and copper as well as middle ear prosthesis of gold, platinum or titanium. Metals were implanted into rat skin and humans. Dissolution and re-crystallization process of the metals was analysed using SEM, TEM, power spectra as well as elemental analysis by EDX and EELS/ESI. Results: Biodegradation of gold was detected, presumably by solving and re-precipitation of gold around implants. Gold cluster, nanoparticles, and mesostructures were detected, formed by dissolution and re-crystallization process. This process results into a migration of gold into the farer off tissue. Cellular filaments as biomolecular templates facilitate the formation of mesostructures. Loss of function of middle ear prosthesis by biodegradation is caused by chronic inflammation and fibrosis. Indeed, similar processes were detected with platinum, but in a very lower level. Conclusion: Noble metal implants undergo biodegradation in oxidative environment in tissue. The dissolution – recrystallization process can be explained by enzyme catalysed redox processes comprising reactive oxygen species and reduction agents as ascorbic acid present in cells and body tissue. Enymes like myeloperoxidase inside lysosomes of inflammatory cells produce hypochloride ions and H2O2 which can dissolve the gold. General significance: The crucial role of the specific chemical environments of gold implants in tissue for their chemical stability and durability of function has been demonstrated. Due to widely use and importance of gold implants, this finding is of general interes.

Published on: 30th November, 2018

OCLC Number/Unique Identifier: 7943307930

Heftiness, a mind boggling interchange among ecological and hereditary factors and is related with critical horribleness and mortality. Utilization of herbs for the administration of heftiness in the ongoing occasions is pulling in consideration. A web and manual based writing overview was led to survey the measure of data accessible on the natural items for weight administration. Customary writing, PubMed, Scopus, Google researcher databases were screened up to February 2012. The pursuit words were “stoutness”, “home grown medication/items/separates”, “restorative plants”, “customary drug”, “Ayurvedic prescription” without narrowing/constraining looking words or components. Distributions just with edited compositions/full articles and books were inspected in the pursuit. In light of the accessible writing, for huge numbers of the natural and weight reduction items, there is minimal distributed data and there have been no clinical preliminaries or the level of proof is restricted. Our writing study additionally demonstrated that these home grown items fall under an adequate level of proof or with no scientific foundation by any stretch of the imagination, or they have a logical discerning however not to an acknowledgment level. Endeavors were made in the audit to characterize the highlights of conceivable natural weight reduction item. A perfect home grown enemy of stoutness item ought to diminish the weight by 10% over fake treatment of treatment by demonstrating a proof of change of bio markers like blood pres-beyond any doubt, lipids and glycemia with no reactions.

Impact of Microplastics on Human Health through the Consumption of Seafood: A Review

Published on: 14th June, 2025

Microplastics (MPs) pose a significant risk to human health, particularly through seafood consumption. Once ingested, MPs can spread from the digestive system to other organs via phagocytosis and endocytosis, leading to toxicological effects. Accumulation of MPs in tissues causes swelling, blockages, oxidative stress, and Cytotoxicity. Studies show MPs alter metabolism, disrupt immune function, and contribute to autoimmune diseases. Chronic exposure has been linked to neurotoxicity, vascular inflammation, and increased cancer risk due to DNA damage. MPs can cross biological barriers, including the placenta, affecting fetal development. Additionally, they serve as vectors for pollutants and bacteria, further complicating health risks. MPs in the bloodstream can trigger inflammatory responses, endothelial adhesion, and red blood cell coagulation, leading to cardiovascular complications. In vitro studies indicate MPs impair renal function and cause long-term inflammation in distal tissues. Moreover, oxidative stress caused by MPs plays a critical role in carcinogenicity. Despite growing evidence of adverse health effects, further research is necessary to understand the full impact of MPs’ exposure on human health and develop effective mitigation strategies.

Non-nutritive Sucking in Preterm Infants-simple Intervention with Substantial Benefits

Published on: 18th June, 2025

Preterm birth, defined as delivery before 37 weeks of gestation, remains a leading cause of neonatal morbidity and mortality globally. One of the developmental challenges in preterm infants is the immaturity of the sucking-swallowing-breathing triad, which hinders successful oral feeding. Non-Nutritive Sucking (NNS) is an innate reflex in neonates that involves sucking motions without the intake of nutrition. This behaviour, often facilitated by pacifiers or a gloved finger, plays a vital role in neurodevelopment, feeding maturity, and physiological regulation in preterm infants. Recent studies also highlight its psychological and lactational benefits for mothers. This review presents a synthesis of current evidence supporting NNS as a low-cost, non-invasive intervention with multidimensional benefits for both preterm infants and their mothers.

Ra-223 dichloride management in a Nuclear Medicine Unit: experience of a referral institution

Published on: 27th August, 2017

OCLC Number/Unique Identifier: 7286425794

Ra-223 dichloride is a first-in-class alpha-emitting radiopharmaceutical recently introduced into clinical practice for treatment of men with Castration-Resistant Prostate Cancer (CRPC) and symptomatic bone metastases. Due to the proven benefit on Overall Survival and the favorable toxicity profile, Ra-223 therapy is gaining widespread use in both US and Europe. In this article, we describe the routinary management of patients undergoing Ra-223 treatment in our Institution. Currently, Ra-223 therapy is indicated for 6 intravenous injections (55 kBq per kg of body weight) administered every 28 days. In comparison to other radiopharmaceuticals, Ra-223 handling and administration do not need any additional training for authorized users. Due to the minimal external dose rate emission, Ra-223 dichloride can be delivered in an outpatient setting. Moreover, no particular precautions other than standard hygiene measures must be taken by patients’ family members or caregivers. Ra-223 therapy is associated to a favorable hematologic toxicity profile, while non-hematologic adverse events are generally mild and easy to manage. Given the favorable toxicity profile of this treatment, clinical trials are currently ongoing to evaluate efficacy and safety of Ra-223 treatment in combination or sequence with recently approved drugs such as abiraterone acetate, enzalutamide and sipuleucel-T. In addition, the recent interest in Ra-223 bone lesion dosimetry could open the way to a dosimetric-based therapeutic approach with Ra-223. In this new scenario, results of these promising clinical trials may help clarifying the optimal sequencing of new therapeutic possibilities for metastatic CRPC and the appropriate eligibility criteria for Ra-223 treatment in oncologic patients.

Evaluation of Uranium in Organs of Residents from an Uranium-Rich Region using Teeth as Bioindicators

Published on: 26th March, 2020

OCLC Number/Unique Identifier: 8588716918

The Uranium extraction and processing plant of INB (Brazilian Nuclear Industries) is in Caetité, a city located in a region hosting the largest Uranium reserve of the country. The degree of Uranium contamination in the Caetité population was investigated before using teeth as bioindicator, where a quite high Uranium concentration was measured in this region, about 160 times higher than the world-wide average. Radiobiological risks are here evaluated from Uranium burdens in organs as skeleton, kidneys, liver, tissues and blood, which were estimated from transfer coefficients and effective internal doses. This was accomplished by means of calculations with the use of the STATFLUX/ICRP approach, plus a set of Uranium transfer rate parameters as function of individual’s age assuming an uninterrupted exposure over a period of 60 years. It was found that U ingestion rates by residents of Caetité are three orders of magnitude higher than worldwide average, indicating that food and water would exhibit high levels of contamination. Calculated effective internal doses range from a minimum of one to a maximum of three orders of magnitude higher than background doses, for blood and bones respectively. The likelihood that this circumstance could lead to serious health problems as e.g. neoplasia is addressed. The methodology presented in this work offers subsidies for further studies on environmental pollution by radionuclides.

AngioJetTM rheolytic thrombectomy induced intravascular haemolysis leading to Acute Kidney Injury requiring Dialysis

Published on: 3rd August, 2018

OCLC Number/Unique Identifier: 7815114583

Background: AngioJetTM rheolytic thrombectomy has been used in the treatment of deep vein thrombosis (DVT) to prevent post-thrombotic syndrome. Though not widely appreciated, it has the potential to cause intravascular haemolysis. Report: A 37 year old man with no previous medical history presented to his GP with a three week history of progressive right upper limb swelling. Doppler imaging confirmed right upper limb DVT and CT scan demonstrated thoracic outlet syndrome. The patient underwent AngioJetTM thrombectomy followed by IV heparin infusion. Successful revascularisation of the occluded vein was achieved. Overnight he developed haematuria, which was initially attributed to IV heparin. Urinalysis however revealed no red cells or casts. Apart from an Hb drop from 134 to 117 his blood profile and blood film showed no abnormality. He subsequently developed progressive oliguria with marked oedema and acute kidney injury (AKI). His creatinine peaked at 1070umol/l at 96 hours post procedure and he was started on intermittent dialysis. He remained dialysis dependent for 6 days. Ultrasound imaging excluded urinary obstruction. Autoimmune and vasculitic serology were negative. Intravascular haemolysis and haemoglobinuria was confirmed by raised LDH (1714u/L) and low haptoglobin (<0.1units). Direct Coomb’s test, Cold agglutinin test and paroxysmal nocturnal haemoglobinuria screen were negative. The patient’s renal function normalised over 3 months. Conclusions: The likely cause of this man’s AKI is heme pigment nephropathy from intra-vascular haemolysis. Increased awareness of this condition may allow early identification and intervention to reduce the risk of renal injury from AngioJetTM associated haemolysis.

High energy lasers and new applications

Published on: 14th August, 2020

OCLC Number/Unique Identifier: 8656784701

In the beginning of 1973 in the USSR the study of possibility of LJE designing was conducted. The reflector, located in the tail of the rocket prototype, concentrated the obtained radiation in air and ensured micro-burst that the reactive thrust was created. The successful results of different models of the reflectors tests, which were at the same time the laser light receivers, had been obtained. One should note that all experiments pointed out above were conducted with the use of electric discharge CO2- lasers with power up to 10 kW, while for the injection into orbit of different highly and technologically effective equipment (global network connections, Internet, photo-monitoring of Earth surface, debris cleaning) the radiated power substantially higher is required. Thus, for example, for SC launching with the weight 1000 kg the laser with power not less than 15 MW is necessary [1,2].

A study of 12c +12c nuclear reaction using a new M3Y-type effective interaction

Published on: 20th August, 2020

OCLC Number/Unique Identifier: 8872658487

This paper is a study of nuclear reactions involving 12c + 12c nuclei carried out with a heavy-ion nucleus-nucleus optical potential derived from a new M3Y-type effective interaction, called B3Y-Fetal, within the framework of optical model at the incident energies of 112, 126.7, 240, 300, 1016 MeV. Folding analyses of the differential cross sections associated with the elastic scattering of the nuclear system, determined at these incident energies with four B3Y-Fetal-based folded potentials constructed from double folding model, have shown the DDB3Y1- and BDB3Y1-Fetal potentials to be the best in excellent agreement with previous work done with the M3Y-Reid. The agreement of the B3Y-Fetal with the famous M3Y-Reid effective interaction, which is also used for folding analysis in this work, is further buttressed and well-established by the findings of this study Herein, the values of the renormalization factor, NR ranging from 1.1117 to 0.8121, obtained with the B3Y-Fetal have been found to be slightly higher, with lower reaction cross sections, aR = 1418 - 1047 millibarns, than NR = 0.9971 - 0.8108 obtained with the M3Y-Reid effective interaction whose accompanying reaction cross sections, being higher, range from 1431 to 1050 millibarns. This depicts the B3Y-Fetal as having a better performance. Additionally, results of folding analyses have shown the best-fit folded potentials, DDB3Y1- and BDB3Y1-Fetal potentials to be in agreement at all incident energies, implying that the cold nuclear matter has an underlying soft equation of state.
