SSR marker-based DNA fingerprinting of Sub1 introgressed lines in the background of traditional rice varieties of Assam India-Supplementary data

Rice varieties are usually characterized by agro-morphological descriptors used for seed certification and seed characterization by following distinctiveness, uniformity, and stability (DUS) test. But in fact, these primary distinguishing morphological descriptors among rice varieties are very limited and hence face problems to distinguish germplasm accessions. Germplasm certification in NBPGR requires a DNA fingerprinting profile to explain germplasm uniqueness compared to existing varieties. Varietal identification has gained a key role worldwide, particularly in plant variety protection. Sixty-two morphological descriptors studies have shown the Sub1 introgressed advanced lines E-6, C-210, C-196, 1189-1 and 1160-1 are distinct from the other varieties for more than 15morphological traits, based on these variations the lines were selected for DNA fingerprinting. About68 SSRs markers were used for DNA fingerprinting in seven genotypes, two of which were parents (Ranjit, Bahadur) and three Sub1 introgressed advanced lines (E6, C210, C196) in Ranjit background, and two Sub1 introgressed advanced lines (1189-1, 1160-1) in Bahadur background. DNA fingerprinting was done on these genotypes of rice using SSR markers. Among the 68 SSR markers, total 65 markers were amplified and three were found not amplified. Out of 65 markersfour of them viz. RM 152, RM 172, RM 251, and RM 346 showed better polymorphism with amplicon size ranges from 155-163 bp, 150-159 bp, 137-147 bp, and 166-175 bp, respectively, and remaining 61 showed monomorphic amplification. Therefore, SSR (Simple-sequence repeats) based DNA fingerprinting helped to differentiate Ranjit, Bahadur, E-6, C-210, C-196, 1189-1, and 1160-1. Hence, the research reveals that newly developed high-yielding Sub1 introgressed advanced lines in the background of traditional Assam rice varieties (Ranjit and Bahadur) are unique in their identity.

Nephrotic Syndrome: A Rare Presentation of AIDS.

The clinical presentation of HIV-associated nephropathy (HIVAN) include proteinuria, typically in nephrotic range (often massive) and renal insufficiency. HIVAN can be an early manifestation of HIV infection. The term HIVAN is reserved for focal segmental glomerulosclerosis (FSGS) but other glomerular lesions may be there. We are reporting a case of nephrotic syndrome (MPGN) in an otherwise asymptomatic HIV-infected patient.

Pseudomembranous Colitis: Do We Need A Screening.

In the last few decades, increasing use of antibiotics has dramatically increased incidences of antibiotic associated diarrhea. An unopposed homing of Clostridium difficile in ICU and wards put forward new challenges for physicians. Development of diarrhea during or just after hospital stay especially in old patients is a typical clinical presentation of C. difficile diarrhea. Cytotoxin assay from tissue culture is a gold standard diagnostic test but its poor availability, high cost, time bound results and rapidly development of life-threatening complications made us to think of a screening test. Demonstration of pathognomonic summit lesions and pseudomembrane with colonoscopy or sigmoidoscopy is relatively inexpensive, easily available and diagnosis is prompt. Our experience in few patients with colonoscopy makes us to recommend it as a screening test for all clinically suspected patients. Till today, it is refuted as first-line investigation because of good number of false negative results but demonstration of pathognomonic lesions even in few patients saves the life with minimal expenditure and least time wastage before initiation of definitive treatment.
