Evaluating CAPO®: A biocompatibility, transparency, and fitment assessment for use with CEREBO® in traumatic intracranial injury detection.

Healthcare-associated infections (HAIs) are a global concern affecting millions of patients, requiring robust infection prevention and control measures. In particular, patients with traumatic brain injury (TBI) are highly susceptible to nosocomial infections, emphasizing the importance of infection control. Non-invasive near infrared spectroscopy (NIRS) device, CEREBO® integrated with a disposable component CAPO® has emerged as a valuable tool for TBI patient triage and this study evaluated the safety and efficacy of this combination. Biocompatibility tests confirmed safety and transparency assessments demonstrated excellent light transmission. Clinical evaluation with 598 enrollments demonstrated high accuracy of CEREBO® in detecting traumatic intracranial hemorrhage. During these evaluations, the cap fitted well and moved smoothly with the probes demonstrating appropriate flexibility. These findings support the efficacy of the CAPO® and CEREBO® combination, potentially improving infection control and enhancing intracranial hemorrhage detection for TBI patient triage. Ultimately, this can lead to better healthcare outcomes and reduced global HAIs.

Genotoxicity evaluation of 1,2 dichlorobenzene in the Indian major carp, Catla catla L. using alkaline comet assay.

The genotoxic effect of 1,2 dichlorobenzene (1,2 DCB), a volatile organic compound in the Indian Major Carp, Catla catla L. was assessed using the alkaline comet assay in the gills and blood. Fish were exposed to various sub-lethal concentrations of 1,2 DCB in vivo. At 24 h, DNA damage scores (expressed as arbitrary units) increased at 0.35 and 0.7 mg/L whereas at 28 days, there was a statistically significant increase in the DNA damage score at all the doses tested (0.175, 0.23, 0.35 and 0.7 mg/L). When the DNA damage scores were considered in the blood samples, the trend was similar to that observed in the gills - significant increase at 0.35 and 0.7 mg/L at 24 h and at all doses at 28 days. The results indicate that 1,2 DCB induces genotoxicity in the form of strand breaks in the DNA of fish as evidenced by the alkaline comet assay.

Antihyperlipidemic effect of iridoid glycoside deacetylasperulosidic acid isolated from the seeds of Spermacoce hispida L. - A traditional antiobesity herb.

ETHNOBOTANICAL RELEVANCE: The interest on herbal health supplements for obesity is increasing globally. Our previous ethnobotanical survey in Tiruvallur district, Tamil Nadu, India indicated the use of Spermacoce hispida L. seeds for the treatment of obesity. AIM OF THE STUDY: This study was aimed to validate the traditional claim and to identify the antihyperlipidemic principle in the seeds of Spermacoce hispida using bioassay guided fractionation method. METHODS: Bioassay monitored fractionation of the aqueous extract from Spermacoce hispida seeds was carried out using triton WR 1339 induced hyperlipidemic animals. It yielded deacetylasperulosidic acid (DAA) as the active ingredient. Pharmacokinetic properties of DAA were predicted using DataWarrior and SwissADME tools. In vitro antiobesity and antihyperlipidemic effects of DAA were evaluated in 3T3L1 preadipocytes and HepG2 cells, respectively. The chronic antihyperlipidemic efficacy of DAA was evaluated in high fat diet fed rats. RESULTS: DAA did not show any mutagenic and tumorigenic properties. It bound with PPARα with comparable ligand efficiency as fenofibrate. The treatment with DAA significantly lowered the proliferation of matured adipocytes, but not preadipocytes. The treatment of steatotic HepG2 cells with DAA significantly decreased the LDH leakage by 43.03% (P < 0.05) at 50 µM concentration. In triton WR 1339 induced hyperlipidemic animals, the treatment with 50 mg/kg dose significantly lowered the TC, TG and LDL-c levels by 40.27, 46.00 and 63.65% respectively. In HFD fed animals, the treatment at 10 mg/kg decreased BMI and AC/TC ratio without altering SRBG. It also improved serum lipid, transaminases and phosphatases levels of HFD fed animals. The treatment lowered adipocyte hypertrophy and steatosis of hepatocytes. CONCLUSION: This preliminary report supported the traditional use of Spermacoce hispida for the treatment of obesity. Further detailed investigations on the long term safety, efficacy and molecular mode of action of Spermacoce hispida and DAA will throw more light on their usefulness for the management of obesity.

Transplacental genotoxicity evaluation of cypermethrin using alkaline comet assay.

Transplacental genotoxic effect of cypermethrin technical was investigated. Three doses (25, 50 and 75 mg/kg body weight) were administered to groups of pregnant Wistar rats during 6-15 days of gestation. Animals were killed on gestation day 20. Fetal blood and liver samples were evaluated for DNA damage using alkaline comet assay. A marginal increase in the mean percentage of DNA damage was recorded in both blood and liver samples of fetuses from cypermethrin-treated dams, but the values were not statistically significant. No skeletal or visceral fetal abnormalities were recorded in treated groups. Nevertheless, the results lead to an understanding that transplacental exposure to cypermethrin can induce low levels of DNA damage in fetuses. This observation could be an explanation for the teratogenic effect exhibited by this chemical in many other studies. The results indicate that cypermethrin may be transplacentally genotoxic. The authors propose more detailed investigations for validating the current findings.
