Neonatal lingual gastric duplication cyst: A rare case report

Enteric duplication cysts occurring in tongue is rare. They present with feeding difficulty and rarely with respiratory distress. A one day old male baby presented with swelling in the oral cavity, interfering with feeding and inability to close the mouth. Under general anesthesia, subtotal excision was done and histopathology was gastric duplication cyst of fundic variety

Mapping and validation of a major QTL for yellow pigment content on 7AL in durum wheat (Triticum turgidum L. ssp durum)

Yellow pigment content in durum wheat (Triticum turgidum L. ssp. durum) is an important criterion for both pasta bright yellow color and human health because of antioxidant properties of carotenoids involved in this pigmentation. In the present study, QTLs for yellow pigment content in durum wheat were mapped in a population of 140 RILs developed from a intraspecific cross between a released variety (PDW 233) and a landrace (Bhalegaon 4). This trait was evaluated in one location for 3 years and in two more locations for one additional year (five different year x location combinations further called "environments"). Yellow pigment content was highly heritable across the five different environments. Analysis of variance showed the significant effect of genotype, environment and genotype x environment interaction on the trait. Five different QTLs linked to yellow pigment content were identified on chromosome 1A, 3B, 5B, 7A and 7B across five different environments. The strongest one located on the distal part of the long arm of chromosome 7A, QYp.macs-7A, explained 55.22% of the variation in the trait, while, remaining four QTLs explained 5-8.75% of phenotypic variation in yellow pigment content. Marker analysis revealed significant association of one ISSR and one AFLP fragment with the trait. These two markers were linked to the major QTL QYp.macs-7A and were converted into SCAR markers. These SCAR markers were further validated on another population as well as 38 diverse genotypes so as to prove their potential in marker assisted selection. These markers will be very useful for the marker assisted breeding of durum wheat for higher yellow pigment content

Transverse Micro-structuring of Photonic Crystal Fibers for Industrial Sensors and Side Viewing Probes for Optical Coherence Tomography Applications

In this work, we report a simple and easily adaptable technique of lateral micro-machining of Photonic Crystal fibers (PCFs) using modulated CO2-laser in conjunction with electrical arc system. The technique is controlled, convenient and precise over wide dimensions (50-250 mm). Lateral access to the holes of PCF provides additional flexibility for sensitive real time detection of gases such as green-house gases. Long period gratings are made in PCF through inscription of micro-grooves for sensitive detection of longitudinal strain. A unique and versatile PCF based probe for possible endoscopic Optical Coherence Tomography (OCT) applications is reported

Nanocarrier-mediated foliar zinc fertilization influences expression of metal homeostasis related genes in flag leaves and enhances gluten content in durum wheat

<div><p>Background</p><p>Wheat is the staple food for most of the world’s population; however, it is a poor source of zinc. Foliar fertilization of zinc via zinc loaded chitosan nanocarriers (Zn-CNP) post-anthesis has proved to be a promising approach for grain zinc enhancement in durum wheat as evidenced in our earlier study. However, the molecular mechanism of uptake of zinc via Zn-CNP remains unclear.</p><p>Methods/Principle findings</p><p>Foliar application of Zn-CNP was performed at post anthesis stages in two durum wheat cultivars (MACS 3125 and UC1114, containing the <i>Gpc-B1</i> gene), and expression levels of several metal-related genes were analyzed during early senescence. Zn-CNP application indeed caused changes in gene expression as revealed by qPCR data on representative genes involved in metal homeostasis, phloem transporters, and leaf senescence. Furthermore, zinc-regulated transporters and iron (Fe)-regulated transporter-like protein (ZIP) family [<i>ZIP1</i>, <i>ZIP7</i>, <i>ZIP15</i>], <i>CA</i> (carbonic anhydrase), and <i>DMAS</i> (2’-deoxymugineic acid synthase) in flag leaves exhibited significant correlation with zinc content in the seeds. The analysis of grain endosperm proteins showed enhancement of gamma gliadins while other gluten subunits decreased. Gene expression within ZIP family members varied with the type of cultivar mostly attributed to the <i>Gpc-B1</i>, concentration of external zinc ions as well as the type of tissue analyzed. Correlation analysis revealed the involvement of the selected genes in zinc enhancement.</p><p>Conclusion</p><p>At the molecular level, uptake of zinc via Zn-CNP nanocarrier was comparable to the uptake of zinc via common zinc fertilizers i.e. ZnSO₄.</p></div
