Agenesis of right lobe of liver; a rare anomaly: a case report

Agenesis of right lobe of liver is a rare finding and was defined as the absence of liver tissue on the right side with preservation of the middle hepatic vein without previous disease or surgery. Congenital agenesis of right hepatic lobe is a rare anomaly which is found incidentally in radiologic examination. Here we present a case of 22 year old female who came with abdominal distension suspecting liver cirrhosis she was investigated and on imaging studies incidentally it was revealed that there is absence of right lobe of liver

Regulation of fruit and wine quality parameters of 'Cabernet Sauvignon' grapevines (Vitis vinifera L.) by rootstocks in semiarid regions of India

Area under wine grape cultivation is increasing in semiarid tropical regions of India. There is lack of information on role of rootstocks influencing must composition and thereby wine quality under such climatic conditions. Majority of area under table grape cultivation is grafted on Dogridge rootstock, which is also been used for wine grapes. Grapes harvested from vines grafted on Dogridge were known to possess high potassium resulting in high pH which has adverse effect on wine quality. Hence, this study was initiated to understand fruit composition and wine quality of 'Cabernet Sauvignon' grapes grafted with each of the rootstocks 101-14Mgt, 1103P, 110R, 140Ru, Fercal, Gravesac and SO4. Rootstocks significantly influenced many of the must composition parameters such as sugars, organic acids, phenolic compounds, potassium and pH. Significant and positive correlation was observed between potassium content, juice pH and malic acid. Rootstocks 101-14 Mgt and Gravesac accumulated more potassium in fruits which also had higher malic acid and juice pH, while it was least on 110R, 1103P, Fercal and SO4 rootstocks. The potassium content in juice was directly related to wine pH, wherein wines made from 'Cabernet Sauvignon' grafted on 101-14 Mgt and Gravesac had highest pH. Content of most of the phenolic compounds in must and wine were significantly influenced by rootstocks. There was more than two fold increase in the total phenolic content from must to wines with highest phenols recorded in wines made from fruits harvested on 110R rootstock

Hierarchical Growth of ZnO Particles by a Hydrothermal Route

The crystallization of ZnO microrods by hydrothermal treatment of a suspension formed from reaction of zinc acetate and sodium hydroxide has been examined using scanning and transmission electron microscopy. Polycrystalline hexagonal ZnO microrods first appeared after 0.5 h reaction time at 120°C. These early stage rods were composed of stacks of hexagonal layers, each ~50 nm in thickness containing closely aligned assemblies of nanocrystallites <20 nm in size. Further growth of the microrods involved columns of nanoparticles extending from the basal layers of the preformed hexagonal stacks. Re-crystallization produced single-crystal microrods, many of which existed as twin particles

Adiantum philippense

Development of an ecofriendly, reliable, and rapid process for synthesis of nanoparticles using biological system is an important bulge in nanotechnology. Antioxidant potential and medicinal value of Adiantum philippense L. fascinated us to utilize it for biosynthesis of gold and silver nanoparticles (AuNPs and AgNPs). The current paper reports utility of aqueous extract of A. philippense L. fronds for the green synthesis of AuNPs and AgNPs. Effect of various parameters on synthesis of nanoparticles was monitored by UV-Vis spectrometry. Optimum conditions for AuNPs synthesis were 1 : 1 proportion of original extract at pH 11 and 5 mM tetrachloroauric acid, whereas optimum conditions for AgNPs synthesis were 1 : 1 proportion of original extract at pH 12 and 9 mM silver nitrate. Characterization of nanoparticles was done by TEM, SAED, XRD, EDS, FTIR, and DLS analyses. The results revealed that AuNPs and AgNPs were anisotropic. Monocrystalline AuNPs and polycrystalline AgNPs measured 10 to 18 nm in size. EDS and XRD analyses confirmed the presence of elemental gold and silver. FTIR analysis revealed a possible binding of extract to AuNPs through –NH2 group and to AgNPs through C=C group. These nanoparticles stabilized by a biological capping agent could further be utilized for biomedical applications

Synthesis of Gold Nanoanisotrops Using Dioscorea bulbifera

Biosynthesis of metal nanoparticles employing plant extracts and thereby development of an environmentally benign process is an important branch of nanotechnology. Here, the synthesis of gold nanoparticles using Dioscorea bulbifera tuber extract (DBTE) as the reducing agent is reported. Field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDX), X-ray diffraction (XRD), and UV-visible absorption spectroscopy confirmed the reduction of gold ions to AuNPs. The anisotropic nanoparticles consist of a mixture of gold nanotriangles, nanoprisms, nanotrapezoid, and spheres. The kinetics of particle formation was time dependent and was enhanced by the increase of temperature from 6°C to 50°C, the optimum being 50°C. The optimum concentration of chloroauric acid was found to be 1 mM. Complete reduction of the metal ions within 5 hours by DBTE highlights the development of a novel ecofriendly route of biological synthesis of gold nanoparticles. This is the first paper on synthesis of gold nanoparticles using DBTE

Magnetic resonance imaging of benign prostatic hyperplasia patients: A retrospective study

The present study was conducted for assessing Magnetic resonance imaging findings of benign prostatic hyperplasia (BPH) patients. The present study was conducted for assessing Magnetic resonance imaging findings of benign prostatic hyperplasia patients. Data of a total of 25 patients with BPH were enrolled. Complete demographic details of all the patients were evaluated. Wasserman NF et al classified BPH types on MRI as follows: type 0, an equal to or less than 25 cm3 prostate showing little or no zonal enlargement; type 1, bilateral TZ enlargement; type 2, retrourethral enlargement; type 3, bilateral TZ and retrourethral enlargement; type 4, solitary or multiple pedunculated enlargement; type 5, pedunculated with bilateral TZ and/or retrourethral enlargement; type 6, subtrigonal or ectopic enlargement; and type 7, other combinations of enlargements. All the details were recorded in Microsoft excel sheet and were assessed using SPSS software. Out of 25 patients, 28 percent and 24 percent of the patients were type 2 and type 4 according to classification as per MRI finding. 20 percent and 16 percent of the patients were type 3 and type 6, whereas 12 percent were type 5 according to classification as per MRI finding.&nbsp
