Performance of cassia [Cinnamomum cassia (Blume)] genotypes under high rainfall and high altitude Kodagu region of Karnataka

Fifteen cassia (Cinnamomum aromaticum) genotypes were evaluated for their performancefor growth and yield characters under high rainfall and high altitude Kodagu region ofKarnataka.  Analysis of fresh and dry bark yield plant-1 after 7 years of planting showedsignificant variation among the genotypes. Among the genotypes, IC370405 exhibitedsuperiority in terms of dry weight (1083 g plant-1) and IC370408 was superior in quality. &nbsp

Primary and revision lumbar discectomy: A three-year review from one center

<b>Background:</b> Despite variations in technique, the results of primary and revision lumbar discectomy have been good. The aim of this study was to retrospectively review cases of primary and revision lumbar discectomy performed in our institute over a three-year period. <b> Materials and Methods:</b> The case records of 273 patients who underwent lumbar discectomy between January 2001-2004 and fulfilled our inclusion and exclusion criteria were reviewed. Of these, 259 were primary discectomies and 14 were revision surgeries. Recurrence was defined as ipsilateral disc herniation at the previously operated level. Demographic parameters, magnetic resonance imaging of the disc, patient satisfaction and rate of recurrence were analyzed. <b> Results:</b> The primary surgery group had 52 (20.08&#x0025;) contained and 207 (79.92&#x0025;) extruded or sequestered discs, while the numbers in the revision group were three (21.43&#x0025;) and 11 (78.57&#x0025;) respectively. "Satisfactory" outcome was noted in 96.5&#x0025; of the primary surgeries, with a recurrence rate of 3.5&#x0025;. In the revision group 78.6&#x0025; had "satisfactory" outcome. In 9.4&#x0025; of the primary group we encountered complications, while it was 21.43&#x0025; in the revision group. <b> Conclusions:</b> Lumbar discectomy is a safe, simple and effective procedure with satisfactory outcome in 96.5&#x0025; of primary disc surgery and 78.6&#x0025; of revision disc surgery

Dosimetric comparison of manual forward planning with uniform dwell times versus volume-based inverse planning in interstitial brachytherapy of cervical malignancies

AimDosimetic comparison of manual forward planning(MFP) with inverse planning(IP) for interstitial brachytherapy(ISBT) in cervical carcinoma.BackgroundBrachytherapy planning by MFP is more reliable but time-consuming method, whereas IP has been explored more often for its ease and rapidness. The superiority of either is yet to be established.MethodologyTwo plans were created on data sets of 24 patients of cervical carcinoma who had undergone ISBT, one by MFP with uniform dwell times and another IP on BrachyVision 13.7 planning system with a dose prescription of 600 cGy. Isodose shaper was used for improving conformity & homogeneity. Dosimetric parameters for target and organs at risk (OARs) were recorded. Conformity index (COIN), dose homogeneity index (DHI), overdose index (OI), Coverage index (CI) and dose nonuniformity ratio (DNR) were calculated.ResultsMean high risk clinical target volume: 73.05(±20.7)cc, D90: 5.51 Gy vs. 5.6 Gy (p = 0.017), V100: 81.77 % vs. 83.74 % (p = 0.002), V150: 21.7 % vs. 24.93 % (p = 0.002), V200: 6.3 % vs. 6.4 % (p=0.75) for IP and MFP, respectively. CI: 0.81(IP) and 0.83(MFP) (p = 0.003); however, COIN was 0.79 for both plans. D2cc of OARs was statistically better with IP (bladder 54.7 % vs. 56.1 %, p = 0.03; rectum 63 % vs. 64.7 %, (p = 0.0008).ConclusionBoth MFP and IP are equally acceptable dosimetrically. With higher dose achieved to the target, for a similar OAR dose, MFP provides greater user flexibility of dwell positions within the target as well as better optimization. Isodose shaper may be carefully used for fine tuning. Larger sample sizes and clinical correlation will better answer the superiority of one over the other

Not AvailableNine genotypes of cardamom (Elettaria cardamomum Maton) along with two commercial cultivars, Green Gold and Appangala 1 were evaluated for their yield and selected horticultural traits. There were significant differences amongst different genotypes with respect to yield and other traits. The genotype IC 349651 was found to be highest in yield (1048.2 kg ha-1) followed by IC 547167 (987.1 kg ha-1). The genotype IC 547167 (Appangala 2) was found to be moderately resistant to Cardamom mosaic virus under artificial conditions and rich in α terpinyl acetate content which was comparable to Appangala 1. In 2014, the genotype IC 547167 was recommended for high yield and resistance to Cardamom mosaic virus under field conditions and released as Appangala 2 for Karnataka and adjoining areas of Kerala. The variety, Appangala 2 (IC 547167) was developed through hybridization between Appangala 1 x NKE 19.Not Availabl

Not AvailableA high yielding clone CHES Selection, of black pepper was evaluated with 10 released varieties for 13 years at CHES (Central Horticultural Experimental Station), Chettalli and KVK (Krishi Vigyan Kendra), Gonikoppal. The comparative performance of this selection revealed that the yield of green berries of 13 year old vine was higher (9.97 kg/vine) than the leading variety of Coorg region i.e. Panniyur -1 (6.71 kg/vine).This clone produced higher yield than all other varieties evaluated. The average spike length was 14.68 cm which was higher than other varieties. The number of berries per spike (93.93) , weight of berries (5.45g/100) and percent recovery (37.22 %) were also higher in the CHES selection than other varieties. This selection was also found superior than the leading variety Panniyur -1 in an observation trial at KVK, Gonikoppal. On this basis this lines was identified and named as Arka Coorg Excel (IC599082) and recommended for the cultivation in the Coorg region of Karnataka.Not Availabl
