Genetic diversity analysis of 46 commercially prominent mandarins grown in different countries was carried out based on molecular and fruit traits. Out of 110 SSR markers, 64 polymorphic markers amplified a total of 155 alleles. Twenty SSR primers revealed 20 unique alleles which generated DNA fingerprints in 17 genotypes. The Polymorphism information content values ranged from 0.13 (CIBE 5156) to 0.73 (CCSM 40), with an average value of 0.45 across all genotypes. The diversity analysis illustrating the genetic relationships classified the genotypes into four major clusters. The ‘Nagpur’ and ‘Mudkhed’ mandarins in cluster I were closely related as these showed the highest genetic similarity having a similarity coefficient of 0.99. In fruit traits, higher heritability (h2) was observed in fruit weight while the higher genotypic coefficient of variation (GCV) was estimated for a number of seeds demonstrating the magnitude of genetic variability in a population.
Looking beyond Piriformis Syndrome: Is It Really the Piriformis?
Shivam Sharma,Harmanpreet Kaur,Nishank Verma,Bibek Adhya 대한고관절학회 2023 Hip and Pelvis Vol.35 No.1
Piriformis syndrome is a common differential diagnosis related to sciatica. The following review provides a concise synopsis of the diagnosis, management, history, and alternatives to diagnosis of piriformis syndrome. A search of the literature for research articles related to piriformis syndrome and associated differential diagnosis of sciatica was conducted. A thorough review of the included articles found that the condition known as piriformis syndrome is over-diagnosed and that potential anatomic and biomechanical variations originating in the pelvic region might be related to the complaint of sciatica. The criteria for diagnosis are based on findings from both physical examination and radio imaging. Piriformis syndrome resembles a variety of clinical conditions; therefore, conduct of future studies should include development of a validated method for evaluation as well as clinical criteria for diagnosis of piriformis syndrome.

<P><B>Abstract</B></P> <P>An innovative and facile sensing approach for common inorganic anions present in aqueous media has been developed using nanocomposites of europium doped graphene quantum dots (GQDs:Eu) with zeolitic imidazole frameworks (ZIF-8). GQDs:Eu, prepared initially by solvothermal approach (at <10nm in diameter), exhibited a strong and intense blue emission at 430nm when dispersed in ethanol. ZIF-8 nanocubes, synthesized on a parallel basis, were in a fairly uniform size distribution (e.g., 185nm in diameter). The formation of nanocomposites by surface adsorption (between GQDs:Eu and ZIF-8) led to significant increase in fluorescence intensity as observed through photo-luminescence spectroscopy. Their interactions with anions (e.g., in terms of variations in the fluorescence intensity) were initially checked against sulfide and other anionic species (e.g., Br<SUP>−</SUP>, Cl<SUP>−</SUP>, F<SUP>−</SUP>, and NO<SUB>3</SUB> <SUP>−</SUP>). Among the tested ions, GQDs:Eu-ZIF-8 were found to effectively and sensitively detect sulfide (S<SUP>2−</SUP>) with significantly high turn on fluorescence. The feasibility of this nanosensing system was explored further toward the detection of S<SUP>2−</SUP> ions. These nanocomposites were thus demonstrated to be feasible for solution-based sensing of S<SUP>2−</SUP> ions with high reproducibility and sensitivity at limit of detection (LOD) of 0.12ppm.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An innovative approach for detection of pollutant sulfide ions is proposed. </LI> <LI> The method is built based upon turn on fluorescence intensity of GQDs:Eu in the matrix structure of Zeolitic Imidazole Framework Nanoparticles. </LI> <LI> Among the tested ions (e.g. S<SUP>2−</SUP>, Br<SUP>−</SUP>, Cl<SUP>−</SUP>, F<SUP>−</SUP>, and NO<SUB>3</SUB> <SUP>−</SUP>), the nanocomposites sensitively detect sulfide (S<SUP>2−</SUP>) with significantly high turn on fluorescence. </LI> <LI> This nanocomposite-based sensing method exhibit high reproducibility and sensitivity at limit of detection (LOD) of 0.12ppm. </LI> <LI> This approach can be extended further to the detection of sulfide ions from environmental samples. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>An innovative and facile sensing approach for solution-based sensing of sulfide (S<SUP>2−</SUP>) anions using nanocomposites of europium doped Graphene Quantum Dots (GQDs:Eu) with Zeolitic Imidazole Frameworks (ZIF-8) has been reported.
