سابقه و هدف: امروزه به منظور بررسی تفاوت های درون گونه ای و نژادی از روش rflp ناحیه igs استفاده می شود. این مطالعه با هدف شناسایی گونه های بیماری زای آلترناریا عامل تولید لکه برگی مرکبات با استفاده از روش های مورفولوژیک و توالی یابی ناحیه its1 در شهرستان ممسنی و نیز بررسی تفاوت های ژنتیکی جدایه های این قارچ بر اساس rflp ناحیه igs انجام گردید. مواد و روش ها: این پژوهش به صورت مقطعی- توصیفی بر ...
background: accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. however, due to a close morphological similarity between the eggs and larval stages of many of these nematodes,such identification is not a trivial task. there are a number of studies showing that molecular targets in ribosomal dna (internal transcri...
Measurements of the dual frequency Global Positioning System (GPS) receivers can be used to calculate the electron density and the total electron content (TEC) of the ionosphere layer of the Earth atmosphere. TEC is a key parameter for investigating the ongoing spatial and temporal physical process of the ionosphere. For accurate estimation of TEC from GPS measurements, GPS satellites and GPS r...
Ulcerative colitis (UC) is a type of inflammatory bowel disease and is considered a chronic gastrointestinal disorder. Igongsan (IGS) is a Korean herbal medicine, which has been used to treat digestive disorders. However, the ameliorative effect and molecular mechanisms of IGS in intestinal inflammation have not yet been studied in detail. The present study aimed to investigate the protective e...
The aim of this study to determine whether the aberrant N-glycosylated serum immunoglobulins (Igs) can be applied as a diagnostic marker of urothelial carcinoma (UC). Between 2009 and 2016, we randomly obtained serum available from 237 UC and also 96 prostate cancer as other cancer controls from our serum bank and also obtained-from 339 healthy volunteers (HV)-controls obtained from community-d...
Post-parturient behavior of mammalian females is essential for early parent-offspring contact. After delivery, lambs need to ingest colostrum for obtaining the related immunological protection, and early interactions between the mother and the lamb are crucial. Despite visual and auditory cues, olfactory cues are decisive in lamb orientation to the mammary gland. In sheep, the inguinal sinus is...
B cell superantigens (SAg) interact with normal human nonimmune Igs (Igs), independently of the light chain isotype, and activate a large proportion of the B cell repertoire. Recently, the major envelope protein of HIV-1, gp120, was found to exhibit SAg-like properties for B cells with potential pathologic consequences for the infected host. This unconventional mode of interaction contrasts wit...
The characteristics of the intergenic spacer rDNAs (IGS rDNAs) of Oesophagostomum dentatum and O. quadrispinulatum isolated from pigs in different geographical locations in Mainland China were determined, and the phylogenetic relationships of the two species were reconstructed using the IGS rDNA sequences. The organization of the IGS rDNA sequences was similar to their organization in other euk...
We present the first interferometric evidence of CO (1–0) emission in the intragroup starburst (IGS) region of HCG 92 (Stephan’s Quintet). BIMA’s large primary beam fully covers both the IGS region and the dominant group member Seyfert galaxy NGC 7319, as well as partially covering the intruder galaxy NGC 7318B. CO emission of *4 j is detected in all of them. The detection of the CO emission as...
Improved gray-scale (IGS) quantization is a known method for re-quantizing digital gray-scale images for data compression while producing halftones by adding a level of randomness to improve visual quality of the resultant images. In this paper, first, analyzing the IGS quantizing operations reveals the capability of conserving a DC signal level of a source image through the quantization. Then,...
