Green synthesis of silver nanoparticles using seagrass Cymodocea serrulata (R.Br.) Asch. & Magnus, characterization, and evaluation of anticancer, antioxidant, and antiglycemic index.

In the present study, the green synthesis of silver nanoparticles (AgNPs) using ethanol extract of Cymodocea serrulata and biological activity were investigated by UV-visible spectrophotometer, Fourier-transform infrared spectroscopy (FTIR), x-ray powder diffraction (XRD), and scanning electron microscopy. The results show that nanoparticles synthesized were confirmed by color change from green to dark brown. The XRD analysis confirmed that the AgNPs were crystalline and found that their UV maximum specific absorbance was between 200 and 400 nm, and their field emission scanning electron microscopy size was between 60 and 69 nm.

Effect of temperature changes on antioxidant enzymes and oxidative stress in gastropod Nerita oryzarum collected along India's first Tarapur Atomic Power Plant site.

Temperature can be considered as pro-oxidant factor that favor the generation of ROS on the species with lower antioxidant efficiency may leads to affect the level of tolerance. So the basic antioxidant enzyme activity (LPO, CAT, SOD, GPx and GST) of gastropod Nerita oryzarum was evaluated at six stations which located between the thermal effluent discharges points from Tarapur Atomic Power Station, India. The antioxidant enzyme activity was shown that all enzyme at discharge point (SII station) where the maximum temperature of heated effluent released.

Effect of Dietary Amino Acids L-Arginine and Lysine on Implant Osseointegration.

Background: Low protein diets have been linked to decreased bone strength in humans. Arginine and lysine can help improve the healing process and stimulate growth factors.

Aim: To evaluate if dietary arginine and lysine combination aids in reducing the time frame for osseo-integration process and bone formation in animal models.

Prevalence of among Denture Wearers and Nondenture Wearers.

Introduction: A denture wearer is highly prone to develop -associated denture stomatitis (CADS) due to the conversion of the normal oral commensal spp. into a pathogen under favorable conditions. Immuno-compromised status, trauma from the prosthesis, other systemic conditions, and improper maintenance of the dentures by the patient are few of the causative agents which turn the oral balance into an unhealthy and unsuitable foundation for the wearing of the prosthesis.

Scientific and Regulatory Policy Committee Points to Consider for Medical Device Implant Site Evaluation in Nonclinical Studies.

Nonclinical implantation studies are a common and often critical step for medical device safety assessment in the bench-to-market pathway. Nonclinical implanted medical devices or drug-device combination products require complex macroscopic and microscopic pathology evaluations due to the physical presence of the device itself and unique tissue responses to device materials. The Medical Device Implant Site Evaluation working group of the Society of Toxicologic Pathology's (STP) Scientific and Regulatory Policy Committee (SRPC) was tasked with reviewing scientific, technical, and regulatory considerations for these studies.

Baseline assessment of marine actinobacterial diversity around the nuclear power plant sites, India and its application to uranium remediation.

Baseline assessments of marine microbial studies are very limited around ecologically sensitive areas of the Nuclear Power Plant (NPP) site with respect to their occurrence, distribution, role in adaptation, and their potential remediation process. The distribution and diversity of marine microbes are largely dependent on the physicochemical parameters relating to a specific area, especially spore-producing marine actinobacteria are a source for indigenous bioremediation agents. Marine actinobacterial diversity with conventional and 16 S rRNA gene analysis was done with different pre-treatment conditions and selective media.

The predominance of Shiga toxin-producing E. coli in the Southeast Coast of India.

In this study, we reported Shiga toxin-producing Escherichia coli (STEC) in 847 samples, including those in coastal waters, sediments, and fish samples in the Southeast Coast of India. A total of 3742 E. coli strains were identified using conventional and molecular identification methods.

A sprayable Acid-Oxidizing solution containing hypochlorous acid (AOS2020) efficiently and safely inactivates SARS-Cov-2: a new potential solution for upper respiratory tract hygiene.

Introduction: To eliminate the COVID-19 pandemic, the transmission of the virus SARS-CoV-2 among the population needs to be blocked and/or at least reduced. Upper respiratory tract viral loads are highest in the early stages of the disease, and high loads are associated with higher mortality rates. This study aims to evaluate the virucidal efficacy of AOS2020, a novel sprayable Acid-Oxidizing solution containing pure and stable hypochlorous acid (HClO), on human coronavirus SARS-Cov-2 in vitro, and the tolerability profile on nasal and oral mucosa suggesting to be a potential solution for upper respiratory hygiene.

A toxicogenomic approach for the risk assessment of the food contaminant acetamide.

Acetamide (CAS 60-35-5) is detected in common foods. Chronic rodent bioassays led to its classification as a group 2B possible human carcinogen due to the induction of liver tumors in rats. We used a toxicogenomics approach in Wistar rats gavaged daily for 7 or 28 days at doses of 300 to 1500 mg/kg/day (mkd) to determine a point of departure (POD) and investigate its mode of action (MoA).

Lyophilized ZB183 Spores: 90-Day Repeat Dose Oral (Gavage) Toxicity Study in Wistar Rats.

A 90-day repeated-dose oral toxicological evaluation was conducted according to GLP and OECD guidelines on lyophilized spores of the novel genetically modified strain ZB183. Lyophilized spores at doses of 10, 10, and 10 CFU/kg body weight/day were administered by oral gavage to Wistar rats for a period of 90 consecutive days. ZB183 had no effects on clinical signs, mortality, ophthalmological examinations, functional observational battery, body weights, body weight gains and food consumption in both sexes.

Acute Histopathologic Findings Related to Needle Puncture Trauma during Subcutaneous Injection in the Sprague-Dawley Rat Model.

It is important to detect injection site reactions during the nonclinical phases of drug development. However, differentiating between normal changes following needle trauma and changes due to the toxicity of injected drugs can be challenging. Therefore, we used the Sprague-Dawley rat model to evaluate the pathological findings expected following a single subcutaneous injection of normal saline.

Reversibility of dopamine receptor antagonist-induced hyperprolactinemia and associated histological changes in Tg RasH2 wild-type mice.

The purpose of this study was to better understand the biological effects of increased prolactin levels induced in mice by dopamine D2 receptor antagonist molindone treatment. Toxicokinetics, prolactin levels, and reproductive tissue histology were evaluated in Tg rasH2 wild-type mice treated orally with molindone at 0, 5, 15, and 50mg/kg/day for 6 months, followed by a 2-month posttreatment recovery period. A greater than dose-proportional increase in molindone exposure ([AUC]0‒24) was observed on Day 180 for both sexes.
