Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS The intensive grading system demonstrated normal marrow iron store in 13 (30.2%), depleted iron stores in 3 (7%), functional iron deficiency in 14 (32.6%), and combined deficiency in 13 (30.2%) patients. Mean log ferritin concentration was lower in patients with depleted iron stores (2.2μg/l) than in those with normal (2.7μg/l), and functional iron deficiency (2.4μg/l). The mean log ferritin in combined deficiency was lower than the mean log ferritin concentration in iron store deficiency (1.9μg/l). CONCLUSIONS The prevalence of functional iron deficiency anemia was greatest when the intensive method for assessment of bone marrow iron was used, thus differentiating four different iron status categories, including functional iron deficiency, from actual iron store deficiency, avoiding unnecessary iron supplementation in the former group.INTRODUCTION Fingerprints, serve as one of the crucial tools for identification of the individual for various purposes. Sex, being one of those tools, researchers have suggested the use of fingerprints for gender identification. The objective of the study was to observe the distribution of various fingerprints patterns in the population of a community, together with the most prevalent pattern. METHODS This descriptive cross-sectional study was conducted in the population of Duwakot VDC, Bhaktapur from May 2019 to July 2019. Ethical clearance was obtained from the Institutional Review Committee with reference no. 2812201804. One hundred and ninety-six individuals of 18 to 60 years of age were enrolled. Fingerprints of all ten fingers were taken and studied to see the distribution pattern and analyzed for gender differences. Simple random sampling was done and the sample size was calculated with a prevalence of 50%. The data obtained were computed and analyzed using Excel to find the results. RESULTS The study showed the highest frequency of loops 1033 (52.71%) followed by whorls 537 (27.38%), arches 300 (15.28%) and composite pattern 90 (4.61%). The radial loops were observed more in the males 397 (5.54%) of total males whereas ulnar loops were observed more in the females 636 (96.38%) of total females. Among whorls, the concentric whorls were seen more in males 245 (52.03%) whereas the spiral whorls were seen more in the females 292 (53.27%). CONCLUSIONS For standard authenticity of the sexual dimorphism, fingerprint patterns, can also be considered for gender identification purposes.INTRODUCTION Perinatal asphyxia is one of the major causes of perinatal and early neonatal mortality in developing countries. The main objective of this study was to observe the prevalence of perinatal asphyxia in babies born at Kathmandu Medical College Teaching Hospital. METHODS This was a descriptive cross-sectional study conducted at Kathmandu Medical College Teaching Hospital over six month period (January to June 2019). All preterm, term and post term babies delivered at Kathmandu Medical College Teaching Hospital were included. Ethical clearance was received from Institutional Review Committee of Kathmandu Medical College (Ref.2812201808). Convenient sampling method was applied. Data analysis was done in Statistical Package for Social Sciences (SPSS 18), point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS A total of 1284 babies delivered over six months period were enrolled in this study and 47 (3.66 %) babies were asphyxiated, at 95% Confidence Interval (2.64%-4.68%). The mean birth weight of asphyxiated babies was 2759.75±65 grams and gestational age was 37.57±2 weeks. Among asphyxiated babies, 15 (32%) babies were normal, 15 (32%) babies were in Hypoxic Ischemic Encephalopathy stage I, 14 (30%) were in stage II and 3 (6%) were in stage III. Twenty Three (49%) asphyxiated babies had antenatal risk factors and all 47 babies had intrapartum risk factors leading to asphyxia. CONCLUSIONS Prevalence of perinatal asphyxia was lower compared to that of other similar tertiary care hospitals. Perinatal asphyxia remains a major cause of neonatal morbidity and mortality.BACKGROUND Endothelial cell (EC) injury is underlies for the pathogenesis of atherosclerosis (AS). MicroRNAs (miRNAs) have been indicated play important role in modulating AS occurrence and development. However, how miR-328-3p modulates EC injury molecular level for AS remains unclear. MATERIAL AND METHODS MiR-328-3p and forkhead box protein O4 (FOXO4) expression were detected using quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. Cell viability was analyzed by Cell Counting Kit-8 (CCK-8) assay. Flow cytometry was utilized to analyze the apoptotic rate. The migration and invasion abilities were measured by Transwell assay. Western blot was applied to examine the expression of C-caspase 3, Beclin, LC3-I, and LC3-II. The levels of interleukin (IL)-1ß, IL-10, and tumor necrosis factor-alpha (TNF-alpha) were tested by enzyme-linked immunosorbent assay (ELISA) assay and western blot. RESULTS MiR-328-3p expression was downregulated in oxidized low-density lipoprotein (ox-LDL) induced human umbilical vein endothelial cells (HUVECs). Overexpressed miR-328-3p obviously alleviated ox-LDL induced inhibition on cell viability, migration and invasion, stimulation on apoptosis, autophagy as well as inflammation in HUVECs. FOXO4 was elevated in ox-LDL HUVECs, and functional assay indicated that FOXO4 aggravated ox-LDL induced HUVECs impairment. In addition, FOXO4 was a target of miR-328-3p in HUVECs; rescue experiments suggested miR-328-3p could protect HUVECs against ox-LDL induced injury via regulating FOXO4. CONCLUSIONS MiR-328-3p protected vascular endothelial cells against ox-LDL induced injury via targeting FOXO4, suggesting a novel insight for atherosclerosis treatment.The current strategies to eradicate bacteria require that the antimicrobial agent either penetrate or disrupt the bacterial membrane. In Escherichia coli (E.coli) as a model of Gram-negative strains, the antimicrobials have to cross two barriers - the outer and the inner membrane being the latter composed by ~ 77% phosphatidylethanolamine (PE), ~ 13% phosphatidylglycerol (PG) and ~ 10% cardiolipin (CL) lipids. Each one of these lipid families shares the same headgroup, but contains acyl chains with varying length and degree of unsaturation. Bacteria adapt their membrane lipid composition and metabolism in response to environmental signals, such as the temperature, resulting in different interactions with exogenous molecules, e.g. antibacterial agents. Herein, bacterial model membranes are prepared to evaluate the lipid-lipid interactions in Langmuir monolayers of binary mixtures at several molar ratios of PE and PG or CL at human physiological temperature (37°C). Both PEPG and PECL monolayers were stable at 37°C and presented higher molecular areas (> 20 Å2/molecule) than at 23°C. However, these lipid mixtures presented liquid-expanded state and rigidity (inverse of the compressibility modulus ~ 90 mN/m) slightly lower than at 23°C. Such athermalicity at biologically relevant temperatures may favour the preservation of the biological functions of E.coli.We aimed to investigate the effects of CX-C chemokine receptor type 4 (CXCR4) on transforming growth factor (TGF)-β1-induced cardiac fibrosis in Human cardiac fibroblasts (HCFs). HCFs were stimulated with TGF-β1, and the level of α-smooth muscle actin (α-SMA) was assessed by immunofluorescence assay. The expression of CXCR4 was detected by Western blotting. Then the cells were incubated with CXCR4 antagonist AMD 3465. Cell viability was measured by CCK-8 assay. The expression of α-SMA, proliferating cell nuclear antigen (PCNA) and Ki67 were examined. Collagen synthesis was detected by sirius red staining. Moreover, the expression of phpspho-Smad2 (p-Smad2) and p-Smad3 were determined. We found that the level of α-SMA was increased after induction with TGF-β1. The expression of CXCR4 was upregulated in TGF-β1-treated HCFs. Following treatment with AMD 3465, cell proliferation was inhibited coupled with a decrease in PCNA and Ki67 expression. Additionally, the expression of α-SMA was decreased after being intervened with AMD 3465. Concurrently, the levels of collagen were reduced accompanied by downregulation of Collagen I and III. Furthermore, AMD 3465 treatment decreased the expression of p-Smad2 and p-Smad3. Our findings suggested that CXCR4 antagonist AMD 3465 could alleviate cardiac fibrosis via blocking TGF-β1-induced activation of Smad2/3 in HCFs.The purpose of our study is to evaluate the effects of the translocator protein (TSPO) ligand etifoxine on muscle tone and locomotor activity. In addition, the mechanism of action of etifoxine on the presynaptic membrane and neuromuscular junction is investigated. These effects of etifoxine were examined employing the following methods 1) in vivo experiments using bar holding test and activity cage test, and 2) comparative in vitro studies with nifedipine on indirectly-elicited twitches of striated abdominal muscle preparations. Etifoxine in doses 50 mg/kg and 100 mg/kg i.p. does not produce any significant changes in locomotor activity and muscle tone of intact rats. Nifedipine (10-5 М) induces a significant decrease in the muscle force of striated muscle preparations. Etifoxine (10-8-10-4 М) has no significant effect on indirectly-elicited twitch tension. Results show that the TSPO ligand etifoxine has no myorelaxant effect. The activation of TSPO is not associated with a reduction in muscle tone and motor impairment. Etifoxine does not affect the presynaptic membrane and its influence on L-type Ca2+-channels is insignificant. Etifoxine does not act as a competitive antagonist of acetylcholine and does not impair the impulse transmission in the neuromuscular junction.The present study aimed to investigate the effects of histone deacetylase 6 (HDAC6) inhibitor Cay10603 (Cay) on high glucose (HG)-stimulated human retinal pigment epithelium (RPE) cells and its underlying mechanisms. ARPE-19 cells were cultured under normal glucose (NG) or high glucose (HG) conditions. The results revealed that HDAC6 was upregulated in HG-stimulated ARPE-19 cells. Cay treatment caused a decrease in intracellular reactive oxygen species (ROS). The levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were reduced accompanied by increase in the activities of superoxide dismutase (SOD) and catalase (CAT) after treatment with Cay. Besides, Cay decreased the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6 and monocyte chemoattractant protein-1 (MCP-1) in supernatant. Meanwhile, the apoptotic rate in Cay-treated ARPE-19 cells notably reduced, coupled with an upregulation in Bcl-2 expression and a downregulation in cleaved caspase-3 and cleaved caspase-9 expression. Cay decreased the expression of phospho (p)-NF-κB p65, p-IκB-α, NLRP3, cleaved caspase-1 and ASC while increased the expression of NF-κB p65 (cytoplasm). Taken together, these findings demonstrated that Cay suppressed HG-induced oxidative stress, inflammation and apoptosis via regulating NF-κB and NLRP3 inflammasome pathway in HG-induced ARPE-19 cells, suggesting that Cay might be a therapeutic agent for the treatment of diabetic retinopathy.
