Aluminium foil dampened the adverse effect of 2100 MHz mobile phone–induced radiation on the blood parameters and myocardium in rats

Mobile phones emit a radiofrequency radiation (RFR) that might have adverse health effects. We aimed to investigate the possible protective effects of aluminium foil (AF) as a physical shield against the RFR from mobile phones on the blood parameters and the myocardium in rats. The effects of whole body 2100 MHz with 0.84–1.86 W/kg of SAR, 4 h/day for 30 days Global System for Mobile Communications (GSM)-RFR exposure for 4 h/day for 30 days on blood parameters (i.e. haemoglobin, leucocytes, thrombocytes, erythrocyte sedimentation rate, white blood cell differential count, corticosterone, CKMB), and the histology of myocardium were investigated. Three-month-old male rats (n = 32) were studied and randomised equally in the following four groups: K1 (non-AF non-RFR control), K2 (AF non-RFR control), P1 (non-AF RFR-exposed), P2 (AF RFR-exposed). Data were analysed with level of significance of p < 0.05. In P1, lower leucocytes and neutrophils counts with high corticosterone levels were found compared with the control groups, whilst a significantly higher CKMB was observed compared with P2 (p = 0.034). Lower cardiomyocyte counts congruent to the area fraction of the non-fibrotic myocardium were observed in P1 compared with the other groups (p < 0.01). AF might decrease the inflammatory-oxidative stress on rodent’s blood cells and myocardium induced by the exposures of radiofrequency radiation of the mobile phones

EXPOSURE TO GOAT BILE FOR 28-DAYS CAUSES HEPATOCYTE INJURY: A HISTOPATHOLOGICAL STUDY

Highlights: 1. Bile consumption, especially goat bile, is believed to have therapeutic effects even though it contains harmful ingredients that can cause toxic effects on the liver 2. The administration of goat bile for 28 days had a toxic effect on the liver of the mice based on histopathological findings Abstract: Background: Bile consumption by Indonesians is believed to have therapeutic effects, especially goat bile. Goat bile is thought to contain harmful ingredients that can cause toxic effects on the liver. However, the 28-days oral toxicity study of goat bile has not been performed. Objective: To analyze the hepatotoxic effect of subchronic administration of goat bile on the liver of mice (Mus musculus). Material and Method: This was an experimental research with a post-test-only control group design. The samples used were 32 Balb/C mice (Mus musculus), which were grouped into 4 groups. The samples were administered with goat bile orally (3.2, 6.4, or 12.8 mL/kg/day) for 28 days. The liver was taken for histopathological examination and the hepatocytes injury score was performed. The scoring results were analyzed using Kruskal-Wallis, Mann-Whitney, and Spearman correlation tests (p<0.05). Result: Goat bile administration was associated with hepatocyte injury (p= 0.004). Groups with goat bile administration of 6.4 and 12.8 mL/kg/day had significant differences with the control group (p= .015 and .029 respectively) and the 3.2 mL/kg/day administered group (p= 0.006 and 0.009 respectively). Moreover, the increased administration of goat bile had a positive correlation with the level of hepatocyte injury (p= 0.004 and r_s= 0.504) Conclusion: Goat bile administration for 28 days had a significant toxic effect on the liver of mice at a dose of 6.4 mL/kg/day

A Rare Case of Dural Tail Sign in the Patient with Glioblastoma Multiforme: A Case Report

Highlight: A dural tail sign was found in T1W1-MR-images with contrast of a patient with glioblastoma multiforme. Glioblastoma multiforme as a grade IV malignancy of the astrocytes' glioma, the dura mater can be infiltrated and shown as DTS, although rarely reported.   ABSTRACT Introduction: The dural tail sign (DTS), which is rarely seen in patients with glioblastoma multiforme (GBM), is reported here. This sign is generally found as a manifestation of meningioma due to the reactive changes of the tumor’s invasion. Case: A 61-year-old Javanese man presented with a gradually worsening headache two months prior to hospital admission. He also suffered from paralysis of his right extremities. His complete blood tests and clinical chemistry were within normal limits. A head CT scan showed a large mass near the convexity of the brain in the left parietal lobe, along with edema and a shift of the midline structures to the right. This was confirmed on the T1W1 MR images with contrast, where DTS was clearly shown. Following surgical resection and tumor excision, histopathology analysis revealed GBM with malignant cell infiltration to the dura in the vicinity of the neoplasm. Conclusion: Here we showed a DTS in GBM as a malignant infiltration marker into the dur

POTENTIAL OF RED OKRA (Abelmoschus esculentus (L.) Moench) ETHANOL EXTRACT TO PROTECT AGAINST 7, 12-DIMETHYLBENZ[A]ANTHRACENE-INDUCED DAMAGE IN RAT’S (Rattus norvegicus) Liver

Highlights: • Red okra pods have a potential antioxidant to protect against DMBA-induced damage in a rat’s liver. • The liver protection with ROE decreased reversible and irreversible cellular damage from 51.8% to 35%, 27.3%, and 18.9%.   Abstract Background: Okra (Abelmonchus esculentus (L.) Moench) is a plant that has potential for humans and health because it contains high antioxidants such as polyphenols. Objective: This study aimed to analyze the red okra pods’ ethanol extract (ROE) antioxidant potential to protect rat (Rattus norvegicus L.) liver against damage by induction of 7, 12-dimethyl-benz[a]anthracene (DMBA). Material and Method: The material used was various doses of red okra pods with ethanol as solvent. Twenty-five female rats (4 weeks, body weight 140—150 g) were divided into five groups: negative control (receiving a single dose of 0.5 mL corn oil as DMBA solvent), positive control (receiving a single dose induction of DMBA 80 mg/kg BW dissolved in 0.5 mL corn oil), and treatment groups 1, 2, 3 (receiving a single dose of DMBA 80 mg/kg BW dissolved in 0.5 mL corn oil and ROE of 50, 100, and 200 mg/kg BW, respectively, daily for 35 days). On day 36, the livers were removed and prepared for histopathological observation using hematoxylin-eosin staining. The method of histopathological score was determined using an ordinal score. Result: The data were analyzed statistically (p>0.05). All ROE doses showed a significant decrease in the histopathological score of rats’ liver damage caused by DMBA-induced. The liver protection with ROE reduced the percentages of reversible and irreversible cellular damage from 51.8% to 35%, 27.3%, and 18.9%, respectively. Conclusion: The red okra pod ethanol extract can protect against DMBA-induced liver damage in rats

The effect of surfactant type on characteristics, skin penetration and anti-aging effectiveness of transfersomes containing amniotic mesenchymal stem cells metabolite products in UV-aging induced mice

Transfersome has been developed to enhance dermal delivery of amniotic mesenchymal stem cell metabolite products (AMSC-MP). AMSC-MP contains many growth factors for managing skin aging, thus improving the quality of an adjusted life year. This study aims to determine the effect of surfactant types acting as the edge activator on transfersome-loading AMSC-MP. Transfersome was prepared by thin-layer hydration method and composed of l-α-phosphatidylcholine as a phospholipid and three types of surfactants, namely; cationic (stearylamine), anionic (sodium cholate), and nonionic surfactant (Tween 80) at a weight ratio of 85:15, respectively. Transfersomes were evaluated for physical characteristics, penetration, effectiveness, and safety. The results showed that sodium cholate, an anionic surfactant, produced the smallest transfersome particle size, i.e., 144.2 ± 3.2 nm, among all formulas. Trans-SA containing stearylamine had a positive charge of 41.53 ± 6.03 mV compared to Trans-SC and Trans-TW, whose respective charges were –56.9 ± 0.55 mV and –41.73 ± 0.86 mV. The small particle size and low negative value of zeta potential enabled high dermal penetration by transfersomes containing AMSC-MP, while the positive charge of stearylamine hindered its penetration of deeper skin layers. Trans-SC and Trans-TW produced higher collagen density values at 77.11 ± of 4.15% and 70.05 ± of 6.95%, than that of Trans-SA. All the AMSC-MP transfersomes were relatively safe with 0.5–1.0 macrophage cell numbers invaded the dermis per field of view. In conclusion, sodium cholate, an anionic surfactant, demonstrated considerable capacity as the edge activator of transfersome-loading AMSC-MP for skin anti-aging therapy

GABRA6 and SLC6A4 genotypes are correlated with the fasting blood glucose and physical fitness in the seemingly healthy young adults

Introduction: We examined environmental and genetic factors potentially correlated with the blood glucose and physical fitness in Kediri, East Java, Indonesia to elucidate the predominant cardiovascular disease risk.Methods:This was a cross-sectional study on 68 adults aged 18-22 years. Direct interview was conducted to get socio-economy, daily diets (rice/ R, snacks and sweets/ SS, veggies and fruits/ VF), daily activity (locomotors and non-locomotors) data. Peripheral blood-GABRA6 and SLC6A4 polymorphisms, fasting blood glucose (FBG), blood pressure, 3 fitness parameters (1 min push-up, 3 minutes step up, pulse rate after 3 minutes step-up) were measured by 2 independent and pre-trained medical doctors. Kruskal-Wallis, Chi-Square, andeta-coefficient tests were used to seek differences between genotypes and correlation strength between variables, respectively (significant if p<0.05).Results:Both gene’s genotypes showed significant correlations with the FBG (p=0.042, p=0.013, respectively); GABRA6 polymorphism significantly correlated with SU (p=0.033). There was a significant difference in the FBG between 2 VF subgroups (p=0.02). Strongest association was found between FBG and SLC6A4 (η=0.3); PR and GABRA6 (η=0.168), PU and SLC6A4 (η=0.38); SU and Locomotors (η=0.237).Conclusions:In these seemingly healthy young adults, daily diets and the genotypes of both genes have a good association with the FBG and physical fitness levels

N-nitrosodiethylamine induces inflammation of liver in mice

Objectives: For designing early treatment for liver cancer, it is important to prepare an animal model to evaluate cancer prevention treatment by using inflammation disease. The hepatocarcinogenic N-Nitrosodiethylamine (NDEA) has been reportedly able to produce free radicals that cause liver inflammation leading to liver carcinoma. This study aimed to evaluate the inflammation disease model of mice induced with hepatocarcinogenic NDEA for five weeks induction. Methods: The BALB-c mice were induced with NDEA 25 mg/kg of body weight once a week for five weeks intraperitonially and it was then evaluated for the body weight during study periods. The mice were then sacrificed and excised for evaluating their organs including physical and morphological appearances and histopathology evaluations. Results: The results showed a significant decrease of body weight of mice after five times induction of 25 mg NDEA/kgBW per week intraperitonially. Different morphological appearances and weight of mice organs specifically for liver and spleen had also been observed. The histopathology examination showed that there were hepatic lipidosis and steatohepatitis observed in liver and spleen, respectively that might indicate the hepatocellular injury. Conclusions: It can be concluded that inducing mice with NDEA intraperitonially resulted in fatty liver disease leading to progress of cancer disease

Dissolving microneedle patches for delivery of amniotic mesenchymal stem cell metabolite products for skin regeneration in UV-aging induced mice

Microneedles offer a promising solution to enhancing dermal delivery of amniotic mesenchymal stem cell metabolite product (AMSC-MP), which contains hydrophilic protein components with high molecular weight, for the purposes of skin rejuvenation and improving human health. This study aimed to evaluate the physicochemical characteristics and in vivo efficacy of AMSC-MP-loaded microneedle patches for effectively regenerating skin tissues in UV-aging induced mice. Dissolving microneedle patches, composed of polyvinyl alcohol with an MW of 9–10 kDa and polyvinylpyrrolidone with an MW of 56 kDa, were fabricated using the double-casting method at three AMSC-MP concentrations: i.e., 30 % (MN30), 25 % (MN25), and 20 % (MN20). The microneedles patches were then evaluated for morphological, mechanical resistance, and insertion properties. An ex vivo release study was also conducted using the Franz cell method, and in vivo efficacy and irritation were then determined through collagen density scores, fibroblast cell counts, and skin irritation studies of UV-aging induced mice. The AMSC-MP microneedles displayed a pyramidal shape with 500 µm sharp tips. Mechanical testing revealed that MN30 achieved its deepest insertion into Parafilm® M (447.44 ± 37.21 µm), while MN25 achieved its deepest insertion into full-thickness porcine skin (717.92 ± 25.40 µm). The study revealed a controlled EGF release for up to 24 h, with MN20 exhibiting the highest deposition (55.94 ± 12.34 %). These findings demonstrate the successful penetration of microneedles through the stratum corneum and viable epidermis. Collagen density scores and fibroblast cell counts were significantly higher in all microneedle formulations than the control, with MN30 having the highest values. Inflammatory cell counts indicated minimal presence suggesting non-irritation in the in vivo study. Dissolving microneedle patches exhibited favorable characteristics and efficiently delivered AMSC-MP with minimal potential for irritation, providing potential technology for delivering biological anti-aging agents for the purposes of fostering skin regeneration.</p
