introduction: tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .this paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  materials and methods: sixty re...

introduction: nodular fasciitis is described as a benign reactive proliferation of myofibroblasts. due to its rapid-growing nature, a precise clinical diagnosis is difficult and the condition is frequently misdiagnosed as malignant lesions.   case report: in this study, we present the case of a young woman with an auricular nodular fasciitis as an example of one of the rarest sites of this tumo...

ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. it also is advertised for cerumen and debris (bacteria and fungi) removal. ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. it is however not free of...

Maize plays an important role both as food and feed throughout the world. For morphological characterization evaluation of yield attributes maize genotypes experiment was carried out at experimental field Department Crop Botany Tea Production Technology, Sylhet Agricultural University (SAU). The materials were seven exotic viz.ZM 0001, ZM 0002, 0003, 0004, 0005, 0006ZM 0007 along with BARI 6 co...

Screening genotypes have a crucial role to increase the efficiency of selections in plant breeding program. Therefore, this study was emphasized determine combining ability and association between traits among themselves yield. The experiment conducted at Haramaya University Research Station (Raare) for two years (2018 2019) using 4x7 alpha-lattice design with three replications. Pooled analysi...

The experiment was carried out at the “La María” Campus of State Technical University Quevedo, located in Mocache canton, province Los Ríos. This consisted establishment experimental lots simple maize hybrid called “Centella”, classified as high yielding and medium segmentation, subjected to different planting densities, which corresponded following treatments: T1 (60 x 25 cm), T2 (70 cm) T3 (8...

The canonical correlation analysis has been successfully used in many areas aiming to extract important information from a pair of data sets. Thus, the objective this work was determine sample size (number plants) required estimate correlations corn characteristics. Six characteristics were measured 361, 373, and 416 plants, respectively, single, three-way double cross hybrids 2008/2009 crop ye...

The fall armyworm, Spodoptera frugiperda (J.E. Smith), is one of the chief pests of maize in the Americas. The study of its spatial distribution is fundamental for designing correct control strategies, improving sampling methods, determining actual and potential crop losses, and adopting precise agricultural techniques. In São Paulo state, Brazil, a maize field was sampled at weekly intervals, ...

1. By use of rabbit isolated perfused intact ears and isolated perfused segments of central and first generation daughter branch ear arteries, we investigated the actions of charybdotoxin (ChTX), a blocker of calcium-activated K+ channels (KCa channels), and N omega-nitro-L-arginine methyl ester (L-NAME) on pressure-flow and diameter-flow relationships. 2. ChTX (1 nM) induced an upwards shift i...

a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...
