The structural and bioactive behaviour of strontium‑doped titanium dioxide nanorods
Rinmayee Praharaj,Snigdha Mishra,Tapash R. Rautray 한국세라믹학회 2020 한국세라믹학회지 Vol.57 No.3
In the present work, various concentrations of strontium ions loaded titanium dioxide nanorods and common titanium dioxide nanorods (control) were synthesized by electrochemical anodization technique to get the implant with superior bioactivity. Cell viability and antibacterial efficacy studies were estimated using MTT assay and solid agar medium. The characterisation results confirmed that Sr2+ was successfully incorporated into TiO2 nanorods. Compared with common TiO2 nanorods (control), Sr2+ loaded TiO2 nanorods showed higher surface roughness, adhesion strength, and water wetting angle. MTT assay showed better cell response on Sr-TiO2 nanorod surface as compared to control and the antibacterial test showed that Sr2+ loaded TiO2 nanorods have superior antibacterial activity against pathogenic bacterial strain E. coli and S. aureus. Sr2+ incorporated TiO2 nanorod arrays can be used as a potential candidate for hard tissue implant applications.
A peculiar liver with surgically and radiologically important variations: a case report

A peculiar liver was found in an adult male cadaver during a dissection class for undergraduate medical students. Th e quadrate lobe and fi ssure for the ligamentum teres were totally absent. Th us, the cystic notch on the inferior border was very broad and deep, and the fundus and body of the gall bladder popped out through this notch. Th e cystic duct terminated into the right hepatic duct at the porta hepatis instead of terminating into the common hepatic duct. Awareness of variations of the lobes and fi ssures may minimize a misdiagnosis of liver problems. Th e aim of the current study was to alert radiologists and surgeons about possible variations in the external appearance and anomalies of the lobes and fi ssures of the liver.
Surgical and radiological importance of a rare cysto-duodeno-colic peritoneal fold

It is quite common to see abnormal peritoneal folds in the abdominal cavity. Some of them might compress or strangulate the viscera and others might determine the direction of the flow of peritoneal fluid, pus or blood. Many unusual clinically important peritoneal folds such as Ladd’s band, cysto-gastro-colic fold, omento-cystic fold, and cysto-colic fold have been reported earlier. Knowledge of these folds is important for radiologists, gastroenterologists, and surgeons. We report an unusual cysto-duodeno-colic fold observed during our dissection classes. The fold was seen to compress the duodenum and colon. The fold extended from the descending part of the duodenum and the transverse colon to the gallbladder. It enclosed the entire gallbladder. A case similar to this has not been reported yet. It is important for the gastroenterologists and laparoscopic surgeons to be aware of this fold to avoid misdiagnosis and iatrogenic injuries.
Sessile ileum, subhepatic cecum, and uncinate appendix that might lead to a diagnostic dilemma
Satheesha B. Nayak,Bincy Muthukattu George,Snigdha Mishra,Sudarshan Surendran,Prakashchandra Shetty,Surekha Devadasa Shetty 대한해부학회 2013 Anatomy & Cell Biology Vol.46 No.4
The subhepatic position of the cecum and appendix is a result of embryological reasons. Subhepatic appendicitis can cause diagnostic dilemmas. During the dissection of an adult male cadaver aged approximately 70 years, the subhepatic position of the cecum and appendix was noted. The appendix made a "U"-shaped bend and its tip was located in the paracolic position. The cecum had appendices epiploicae, and the terminal part of the ileum was retroperitoneal and had ascended vertically to the cecum from the right iliac fossa. Functionally, the sessile part of the ileum might restrict its peristaltic movements. The abnormal position of the terminal ileum might be mistaken for an ascending colon during laparoscopic surgery. The subhepatic position of the cecum and appendix might cause confusion in the diagnosis of acute appendicitis because the tenderness in such cases is not located at the McBurney's point.

Hybrid rice has a considerable yield advantage over inbred lines, but the adoption rate in India is quite slow. In a three-line hybrid rice breeding programme, the development of fertility restorer lines that have enhanced grain quality is crucial. Employment of doubled haploid (DH) technology will accelerate the development of improved R lines in a short period of time, thus hastening the pace of hybrid rice breeding. This investigation was carried out for the evaluation of genetic diversity and assessment of population differentiation in 113 DHs derived from BC1F1s of IMP. IR 42266-29-3R and Nagina 22. A total of 46 SSR (Simple Sequence Repeat) markers resulted in an average of 2.00 alleles per locus. Polymorphism information content (PIC) value ranged from 0.31 to 0.37 with an average of 0.36. RM496, RM25520, RM483 and RM553 were found to be the best markers for the identification of genetic diversity. Structure analysis classified 113 DHs into four groups, which matched the Neighbour-Joining method using UPGMA cluster analysis. The AMOVA results demonstrated substantial genetic variations within subpopulation than among sub-population. The SSR marker-based molecular fingerprinting could serve as a sound basis in the identification of genetically distant as well as in the duplicate sorting of the morphologically close population in future breeding programmes
