RESUMEN
In the present study 220 stool samples collected from diarrheic children admitted to different hospitals and nursing homes of Uttar Pradesh and Uttarakhand were screened for rotavirus. Of 220 diarrheic samples screened 46 samples were found to be positive for rotavirus by RNA PAGE. All the isolates exhibited 4-2-3-2 migration pattern suggesting group A rotavirus. Both long and short electropherotypes were prevalent in these regions. Six different electropherotypes were detected in this study period. Male diarrheic children were found to be more susceptible to rotavirus infection (22.96 %) than that of the female ones (17.64 %). Viral RNA isolated from stool samples again subjected to VP4 gene amplification by RT-PCR using con2 and con3 primer which resulted 876 bp product suggesting group A rotavirus. Besides virus isolation was successfully done using MA104 cell line.
RESUMEN
Nano-particle embedded system plays an importance in developing of future terahertz (THz) radiation source for real-world applications. The laser interactions with nanoparticle embedded system can produce a wide range of THz radiation due to plasma oscillations excitation. We investigate THz field generation from the laser-beat wave interaction with a mixture of spherical and cylindrical graphite nanoparticles in argon gas. Different laser intensity distributions such as Gaussian, cosh-Gaussian, flat-top and ring shape laser pulses have been studied in this work. The relevant plasmon resonance conditions with appropriate symmetry of spherical nanoparticles and cylindrical nanoparticles are discussed. THz field is enhanced upto the order of 10 2 when the laser intensity redistributes along the polarization direction for a ring shape field envelope.
RESUMEN
Although the health benefits of exercise in adults with obesity are well described, the direct effects of exercise on adipose tissue that may lead to improved metabolic health are poorly understood. The primary aims of this study were to perform an unbiased analysis of the subcutaneous abdominal adipose tissue transcriptomic response to acute exercise in adults with obesity, and to compare the effects of moderate-intensity continuous exercise versus high-intensity interval exercise on this response. Twenty-nine adults with obesity performed a session of either high-intensity interval exercise (HI; 10 × 1 min at 90%HRpeak, 1 min recovery between intervals; n = 14) or moderate-intensity continuous exercise (MI; 45 min at 70%HRpeak; n = 15). Groups were well matched for BMI (HI 33 ± 3 vs. MI 33 ± 4 kg/m2), sex (HI: 9 women vs. MI: 10 women), and age (HI: 32 ± 6 vs. MI: 29 ± 5). Subcutaneous adipose tissue was collected before and 1 h after the session of HI or MI, and samples were processed for RNA sequencing. Gene set enrichment analysis revealed 7 of 21 gene sets enriched postexercise overlapped between HI and MI. Interestingly, both HI and MI upregulated gene sets involved in inflammation (IL6-JAK-STAT3 signaling, allograft rejection, TNFα signaling via NFκB, and inflammatory response; FDR q value < 0.25). Exercise also downregulated adipogenic and oxidative metabolism gene sets in both groups. Overall, these data suggest genes involved in subcutaneous adipose tissue metabolism and inflammation may be an important part of the initial response after a session of exercise.NEW & NOTEWORTHY This study compared the effects of a single session of high-intensity interval exercise versus moderate-intensity continuous exercise on transcriptional changes in subcutaneous abdominal adipose tissue collected from adults with obesity. Our novel findings indicate exercise upregulated inflammation-related gene sets, while it downregulated metabolism-related gene sets - after both high-intensity and moderate-intensity exercise. These data suggest exercise can alter the adipose tissue transcriptome 1 h after exercise in ways that may impact inflammation and metabolism.

The development of self-cleaning and anti-fogging durable superliquiphobic coatings for aluminum surfaces has raised tremendous interest in materials science. In this study, a superliquiphobic coating is fabricated on an aluminum surface by a single-step dip-coating method using 1H,1H,2H,2H-Perfluorooctyltrichlorosilane-modified SiO2 nanoparticles. The successful implementation of the aforesaid coating in different applications requires extensive investigations of its characteristics and stability. To understand the properties of the coating, surface morphology, contact angle, self-cleaning, anti-fogging, and water repellency were investigated under perturbation conditions. Additionally, the dynamics of water and oil on the coated sample also were studied. Furthermore, the durability of the coating also was examined by performing thermal, chemical, and mechanical stability tests. It was found that the coating is superliquiphobic for water, ethylene glycol, glycerol and hexadecane, and shows thermal, chemical, and mechanical stability. Further, it exhibits self-cleaning and anti-fogging properties. This approach can be applied to any size and shape aluminum surface; thus, it has great industrial applications.
RESUMEN
This paper integrates the evidential reasoning methodology with the parallel distributed learning paradigm of artificial neural networks (ANN). As such, this work presents an algorithm for the detection and, if possible, subsequent correction of the errors in the neuron responses in the output layer of the multiple adaptive linear element (MADALINE) ANN. A geometrical perspective of the MADALINE ANN processing methodology is provided. This perspective is then used to formulate a statistical specification to identify and quantify the sources of uncertainties in the MADALINE processing methodology. A new algorithm, EMRII, is then developed as an extension to the original MRII (MADELINE rule II) algorithm, to formulate support and plausibility measures based on the statistical specification. The support and plausibility measures, thus formulated, are indicative of the degree of confidence of the ANN, in regards to the correctness of its outputs. Based on the support measure, a scheme utilizing two thresholds is proposed to facilitate the interpretation of the support values for error prediction in the ANN responses. Finally, simulation results for the application of the EMRII algorithm in the prediction of erroneous responses in an example problem is presented. These simulation results highlight the error detection capabilities of the EMRII algorithm.
RESUMEN
Accidental swallowing of a gold cast crown that became loose after separation with brass wire for orthodontic band placement, is reported. The intervention to remove the ingested crown subsequent to its location in the GI tract on immediate radiographic examination of chest and abdomen included endoscopic examination. Since the crown had past distal to the duodenum it was decided to keep a watch on its movement by daily radiographic examination. The crown passed with excreta on the 5th day uneventfully. Literature on ingestion of foreign bodies of dental origin is reviewed. Possible emergencies and their management is discussed.

The present case control study was done on 50 cases of oral cancer and 50 controls These two groups are compared after taking the history in detail with special emphasis on the tobacco and alcohol intake. My various statistical tests, we correlated the strength of association between tobacco/alcohol intake and development of oral cancer. Tobacco only and combined exposure to tobacco and alcohol was found to be strongly related to the development of oral cancer but alcohol alone does not have significant role in causation of oral cancer.
RESUMEN
Fifty children with head and neck masses were evaluated clinically and pathologically. Inflammatory swellings constituted the majority (54%). Congenital - developmental malformations were the next common lesions (30%) and neoplastic masses constituted the rest (16%). Tuberculous lymphadenitis was found to be the single most common etiology (28%). Among congenital-developmental malformations, cystic hygroma was the most frequent lesion. The incidence of branchial cleft abnormalities was found to be low and no thyroglossal duct cyst was observed in this series. Among the neoplastic masses malignant lesions were more common than benign tumours and lymphoma was the most common head and neck malignancy observed.
RESUMEN
This new tympanoplasty technique with homo-ossicles (25 cases) has evolved as a reliable, effective, and durable technique to construct the middle ear conduction system when the total ossicular chain is missing. The isolated footplate is driven by two (primary and secondary) neotympanic membranes; hence this new technique is designated as "twin tympanoplasty." The initial hearing results (air-bone gap closure to 10 dB or less in 88% of the cases) have been good, and follow-up (six to 14 months) audiograms suggest that the hearing gain may survive the test of time. Toenail autograft could be one substitute for the ossicle as proved by satisfactory results in five cases.
