Glioblastoma (GBM) is the most malignant primary tumor in the brain, with poor prognosis and limited effective therapies. Although Bevacizumab (BEV) has shown promise in extending progressionfree survival (PFS) treating GBM, there is no evidence for its ability to prolong overall survival (OS)

As seed oil content (OC) is a key measure of rapeseed quality, better understanding the genetic basis of OC would greatly facilitate the breeding of high-oil cultivars. Here, we investigated the components of genetic effects and genotype × environment interactions (GE) that govern OC using a full diallel set of nine parents, which represented a wide range of the Chinese rapeseed cultivars and pure lines with various OCs.

This work demonstrates the fabrication of a highly selective ammonia (NH3) gas sensor based on Graphene/SilvereSilver Oxide/Polypyyrole (Gr/AgeAg2O/PPy) nanocomposite. To archive this objective, a cost-effective, room temperature mediated solution-based synthesis of Gr/AgeAg2O/PPy nanocomposite was exploited as an efficient performance NH3 gas sensor through combining the exceptional electrical characteristics of Graphene and sensing abilities of AgeAg2O/PPy.

This study investigates the possible synergistic stimulatory effects of prebiotic chitooligosaccharide and some commercial prebiotics on probiotic growth. Different combination of chitooligosaccharide with inulin, fructooligosaccharide, and lactulose were prepared and their ability to stimulate the growth of probiotic strains was evaluated. Following Chou-Talalay method, the combination index was calculated and used for synergistic assessment.

This combination of paclitaxel and curcumin gave a higher efficiency of both drugs in cytotoxicity, induced apoptosis, and effect on cell cycles of KPL4 cell line in comparison with the use of paclitaxel or curcumin alone or even a normal mixture of these two compounds. Furthermore, PTX-Cur/PLA-TPGS nanoparticles exhibited a powerful ability in preventing MCF7 spheroids growth. Interestingly, curcumin also functioned as both a drug and a label. Based on the autofluorescence of curcumin, the absorption of PTX-Cur/PLA-TPGS nanoparticles into MCF7 spheroids could be followed and calculated.

Ferulic acid (FA; 3-methoxy-4-hydroxycinnamic acid) can eliminate stress-induced damage because of its ability to induce antioxidant activity under stress. The aim of this study was to identify the effects of FA on water status, antioxidant system, and lipid peroxidation in wheat (Triticum aestivum L.) roots exposed to boron (B) stress. Plants were grown in hydroponic culture containing the combination or alone form of 25–75 μM FA and 4–8 mM B. Stress significantly decreased growth (RGR), water content (RWC), proline content (Pro), and osmotic potential (YP).

The cotyledons are suitable materials to create multiple shoot for GmCHI transgenic T. paniculatum when using the MS medium supplemented with kinetin. The addition of 2.0 mg/l of BAP gave a higher multi-shooting effect than the addition of 1.5 mg/l of kinetin or the combination of 1.5 mg/l of kinetin with 0.8 mg/l of IBA. Using 0.5mg/l IAA had better rooting ability than combining 0.5mg/l IAA with kinetin.

The present investigation was undertaken for combining ability studies on quantitative and qualitative traits at C.H.F., CAU, Pasighat, A.P. The 28 F1 hybrids were developed by crossing 8 diverse brinjal genotypes/varieties in half diallel fashion. The variances due to GCA and SCA were significant for most of the characters indicating the importance of both additive and non-additive gene action in the inheritance of these characters.

Heterosis or hybrid vigour is the increased or decreased vigour growth, fitness or yield of a hybrid over the parental values, resulting from the crossing of genetically divers genotype. Heterosis has positive association with specific combining ability (sca) variance. For the development of effective heterosis breeding programme in sweet sorghum, one needs to have information about genetic architecture and estimated prepotency of parents in hybrid combinations.

The study becomes much more reliable if a good degree of correspondence is observed between various genetic estimates over filial generations. Further, extent of heterosis will have direct effect on breeding methodology in varietal improvement programmes. Therefore, keeping aforesaid considerations in view, present study was undertaken in soybean to evaluate, identification and selection of better nutritional quality genotypes.
