RESUMEN

Background: Dental anxiety is a matter of serious concern to pediatric dentists as it may impede the efficient delivery of dental care. If not adequately resolved, a persistent negative response pattern may emerge. Thaumaturgy, commonly known as magic trick, has become popular recently. It is a tool that distracts and relaxes the child by using magic trick while the dentist performs necessary treatment. Hence, the aim of this study was to evaluate the effectiveness of Thaumaturgic aid in alleviation of anxiety in 4-6 - year-old children during administration of local anesthesia using the inferior alveolar nerve block (IANB) technique. Methods: Thirty children aged between 4-6 years with dental anxiety requiring IANB were included in this study. Patients were divided equally into two groups: Group I, thaumaturgic aid group and Group II, conventional non-pharmacological group using randomization. Anxiety was measured before and after using the intervention with Raghavendra Madhuri Sujata-Pictorial scale (RMS-PS), Venham's anxiety rating scale, and pulse rate. All the data were tabulated and compared using statistical analysis. Results: Children in thaumaturgy group (Group- I) exhibited significantly lower anxiety during IANB in comparison with children in the conventional group (Group- II) and the difference was statistically significant. Conclusion: Magic tricks are effective in reducing anxiety among young children during IANB; Moreover, it expands the arsenal of behavior guidance techniques for treatment of children with anxiety and plays an important role in shaping the behavior of a child in pediatric dentistry.

RESUMEN

This study aimed to assess the combined use of extraoral vibratory stimulation and extraoral cooling in reducing the pain (subjective and objective) of dental local anesthesia administration in children. PubMed, Cochrane Central Register of Controlled Trials, and Ovid SP databases were searched up to July 2021. Article titles were screened and full-text evaluations of the selected articles were performed. Finally, seven studies (391 children, aged 4 - 12 years) were included in this qualitative and quantitative analysis. The pooled data determined the combined effect of extraoral vibration and extraoral cooling as a single measure. Extraoral vibration or cooling alone were not compared. The measured primary and secondary outcomes were pain perception and subjective and objective pain, respectively. When compared with the control, extraoral vibration and cooling resulted in significant differences in the mean combined data for the variables, pain perception, and pain reaction. Children's subjective pain as measured by pain scores were reduced when extraoral vibration and cooling was used during local anesthesia administration (mean difference -3.52; 95% confidence interval [-5.06 - 1.98]) and objective pain (mean difference -1.46; 95% confidence interval [-2.95 - 0.02] ; mean difference -1.93; 95% confidence interval [-3.72 - 0.14]). Within the confines of this systematic review, there is low-quality evidence to support the use of combined extraoral vibration and cooling for reducing pain (subjective and objective) during intraoral local anesthesia administration in children.

RESUMEN

The complexities of multi-use landscapes require sophisticated approaches to addressing disease transmission risks. We explored gastro-intestinal nematode (GINs) infections in the North India Trans-Himalayas through a socio-ecological lens, integrating parasite transmission modelling with field surveys and local knowledge, and evaluated the likely effectiveness of potential interventions. Bharal (blue sheep; Pseudois nayaur), a native wild herbivore, and livestock share pasture year-round and livestock commonly show signs of GINs infection. While both wild and domestic ungulates had GINs infections, egg counts indicated significantly higher parasite burdens in bharal than livestock. However, due to higher livestock densities, they contributed more to the total count of eggs and infective larvae on pasture. Herders also reported health issues in their sheep and goats consistent with parasite infections. Model simulations suggested that pasture infectivity in this system is governed by historical pasture use and gradually accumulated larval development during the summer, with no distinct short-term flashpoints for transmission. The most effective intervention was consequently predicted to be early-season parasite suppression in livestock using temperature in spring as a cue. A 1-month pause in egg output from livestock could lead to a reduction in total annual availability of infective larvae on pasture of 76%, potentially benefitting the health of both livestock and bharal. Modelling suggested that climate change over the past 33 years has led to no overall change in GINs transmission potential, but an increase in the relative influence of temperature over precipitation in driving pasture infectivity. Our study provides a transferable multi-pronged approach to investigating disease transmission, in order to support herders' livelihoods and conserve wild ungulates.

RESUMEN

The beauty and golden proportions of a face are largely determined by the shape and size of the nose one inherits. When the subunits of the nasal structure are considered, the width and structure of Ala and Alar rims determine to a large extent the beauty of the nose itself. Various classifications exist to evaluate the alar rim deformities that are inherited as well as iatrogenic, but occurrence of twin alar rims as a deformity has rarely been reported. This article reports the deformities of drooping tip, hanging columella, and asymmetry of alar rims along with twin alar rims. All the problems were addressed with an open rhinoplasty approach and combining the alar incision with the sail technique to achieve the correction of twin alar rim.

RESUMEN

The antagonistic potential of Trichoderma strains was assayed by studying the effect of their culture filtrate on the radial growth of Sclerotium rolfsii, the causal agent of chickpea collar rot. Trichoderma harzianum-1432 (42.2%) and Trichoderma atroviride (40.3%) were found to be strong antagonists. To enhance their antagonistic potential, mutagenesis of these two selected strains was performed. Two mutants, Th-m1 and T. atroviride m1, were found to be more effective than their parent strains. The enzymatic activities of the selected parent and mutant strains were assayed, and although both mutants were found to have enhanced enzymatic activities compared to their respective parent strains, Th-m1 possessed the maximum cellulase (5.69U/mL) and ß-1,3-glucanase activity (61.9U/mL). Th-m1 also showed high competitive saprophytic ability (CSA) among all of the selected parent and mutant strains, and during field experiments, Th-m1 was found to successfully possess enhanced disease control (82.9%).

RESUMEN

BACKGROUND: Posts are used to enhance crown buildup in pulpless teeth with destructed crown portion. Different types of post are used in endodontically treated teeth. The aim of the present in vitro study was to evaluate fracture resistance of custom made, metal, glass fiber reinforced and carbon reinforced posts in endodontically treated teeth. MATERIALS AND METHODS: An in vitro study was carried out on extracted 40 human maxillary central incisor teeth, which was divided into four groups with 10 samples in each group with custom made, metal post, glass fiber reinforced, and carbon reinforced posts. The samples were decoronated at cemento-enamel junction and endodontically treated. Post space was prepared and selected posts were cemented. The composite cores were prepared at the height of 5 mm and samples mounted on acrylic blocks. Later fracture resistance to the compressive force of samples was measured using Universal Testing Machine. RESULTS: The maximum resistance to the compressive force was observed in carbon reinforced and glass fiber reinforced posts compared others which is statistically significant (P > 0.001) and least was seen in custom fabricated post. CONCLUSION: It is concluded that carbon reinforced fiber post and glass fiber posts showed good fracture resistance compared to custom made and metal posts.

RESUMEN

<p><b>OBJECTIVE</b>To compare and elucidate the antioxidant efficacy of ethanolic and hydroethanolic extracts of Indigofera tinctoria Linn. (Fabaceae family).</p><p><b>METHODS</b>Various in-vitro antioxidant assays and free radical-scavenging assays were done. Quantitative measurements of various phytoconstituents, reductive abilities and chelating potential were carried out along with standard compounds. Half inhibitory concentration (IC50) values for ethanol and hydroethanol extracts were analyzed and compared with respective standards.</p><p><b>RESULTS</b>Hydroethanolic extracts showed considerably more potent antioxidant activity in comparison to ethanol extracts. Hydroethanolic extracts had lower IC50 values than ethanol extracts in the case of DPPH, metal chelation and hydroxyl radical-scavenging capacity (829, 659 and 26.7 μg/mL) but had slightly higher values than ethanol in case of SO2- and NO2-scavenging activity (P<0.001 vs standard). Quantitative measurements also showed that the abundance of phenolic and flavonoid bioactive phytoconstituents were significantly (P<0.001) greater in hydroethanol extracts (212.920 and 149.770 mg GAE and rutin/g of plant extract respectively) than in ethanol extracts (211.691 and 132.603 mg GAE and rutin/g of plant extract respectively). Karl Pearson's correlation analysis (r2) between various antioxidant parameters and bioactive components also associated the antioxidant potential of I. tinctoria with various phytoconstituents, especially phenolics, flavonoids, saponins and tannins.</p><p><b>CONCLUSION</b>This study may be helpful to draw the attention of researchers towards the hydroethanol extracts of I. tinctoria, which has a high yield, and great prospects in herbal industries to produce inexpensive and powerful herbal products.</p>

RESUMEN

The present study describes the genotypic distribution of rotaviruses (RVs) in an Indian bovine population with unexpectedly higher proportions of G3 alone or in combination of G8/G10. PCR-genotyping confirmed that 39.4% (13/33) of the prevalent RVs were the G3 type while 60.6% (20/33) were dual G3G10 or G3G8 types. P typing revealed that 93.9% (31/33) of the samples were P[11] while 6.1% (2/33) possessed a dual P[1]P[11] type. Sequence analysis of the VP7 gene from G3 strains viz. B-46, 0970, and BR-133 showed that these strains had sequence identities of 90.5% to 100% with other bovine G3 strains. The highest identity (98.9% to 100%) was observed with RUBV3 bovine G3 strains from eastern India. The G3 strains (B-46, 0970, and BR-133) showed 97.5% to 98.8% sequence homologies with the Indian equine RV strain Erv-80. Phylogenetic analysis demonstrated that G3 strains clustered with bovine RUBV3 and J-63, and equine Erv-80 G3. Overall, these results confirmed that the incidence of infection by RVs with the G3 genotype and mixed genotypes in the bovine population was higher than previously predicted. This finding reinforces the importance of constantly monitoring circulating viral strains with the G3 genotype in future surveillance studies.

RESUMEN

OBJECTIVE@#To develop a standard enzyme-linked immunosorbent assay (ELISA) for the detection of bovine herpesvirus type 1 (BHV-1).@*METHODS@#The assay was based on hyperimmune rabbit and guinea pig antisera raised against purified BHV-1. Polyethylene glycol precipitation and sucrose density gradient methods were adopted for viral concentration and purification. Antisera were raised using Freund's adjuvant followed by extraction of IgG of high purity.@*RESULTS@#Optimum antisera dilutions as determined by titrations were chosen as 1:4 000, whereas the conjugate was used at 1:2 000 dilution. Using 95 clinical specimens, the ELISA test showed a sensitivity and specificity of 91.90 % and 93.10 %, respectively when compared to PCR. The cut-off value was fixed at 0.15 (A(490)) and a P/N ratio of >1.30 indicated a significant positive reaction.@*CONCLUSIONS@#The results have demonstrated that this ELISA could efficiently detect BHV-1 and can be used as an important diagnostic tool.

RESUMEN

Fat, oil and grease in wastewater can be difficult to treat because of their slow decomposition. Traditional pretreatment facilities to remove fat, oil and grease from wastewater are increasingly costly. The hypothesis in this study was that pretreatment of animal fat-containing wastewater in sand and sand/gravel filters facilitates the conversion of slowly degradable organic matter measured as the difference between chemical oxygen demand (COD) and 5-day biochemical oxygen demand (BOD(5)) for subsequent biological treatment. The pretreatment was evaluated using simulated turkey-processing wastewater and coarse sand and sand/gravel filters at a constant hydraulic loading rate of 132L/m(2)/day. Two types of fixed media reactors were employed: (i) one set with a varying depth of coarse sand, and (ii) the second was similar but with an additional pea gravel cap. The results indicated that the relative removal of COD was slightly improved in the sand bioreactors with a pea gravel cap irrespective of the depth of coarse sand, but partial conversion to BOD(5) was not consistently demonstrated. Pea gravel may act as a sieve to entrap organic matter including fat globules from the wastewater. Multiple dosing at the same daily loading rate slightly improved the treatment efficiency of the sand bioreactors. The ratios of influent-COD/effluent-COD were always greater than 1.0 following a change in the dosing frequency after a rest period, suggesting that organic matter, specifically fat globules in this case, was retained by the column matrix.

RESUMEN

The present study evaluates the effect of temperature on the sensitivity of the freshwater tubificid sludge worm Tubifex tubifex Müller to 10 heavy metal ions. Metals used in this study were cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, nickel, and zinc. The acute toxicity of these heavy metals was studied at 15, 20, 25, and 30 degrees C. The percentage mortality, relative toxicity, and EC50 values and their 95% confidence limits from 24 to 96 h were determined at varying temperatures. The EC50 values (mg/liter) of metal ions at 15 degrees C were Hg2+, 0.034; Cu2+, 0.340; Cr6+, 1.846; Zn2+, 10.99; Ni2+, 25.10; Cd2+, 56; Fe3+, 86.09; Co2+, 239.39; Pb2+, 456.76; and Mn2+, 164.55. At 30 degrees C the values were Hg2+, 0.014; Cu2+, 0.031; Cr6+, 0.872; Zn2+, 3.37; Ni2+, 18; Cd2+, 28.55; Fe3+, 71.26; Co2+, 95.35; Pb2+, 165.22; and Mn2+, 239.39. The results indicate that the acute toxicity of cadmium, chromium, cobalt, copper, lead, mercury, nickel, and zinc increases with temperature increase. The toxicity of manganese was not influenced by temperature, and temperature had little effect on iron toxicity. The rank order of toxicity of metal ions at 15, 20, 25, and 30 degrees C is presented and discussed. It is concluded that temperature is an important factor in short-term acute toxicity tests. The study indicates that seasonal temperature changes are an important variable in determining the amount of heavy metals that may be safely released from metal industries and other similar sources into the aquatic environment. Influence of temperature on the short- and long-term toxicity of chemicals should be considered for establishing appropriate water-quality criteria and standards to protect aquatic flora and fauna and human health.
