fulvescens aqueous algal extract (without CfAgNPs) showed irregular confluent aggregates with round polygonal cells, similar to the untreated control. Tamoxifen- (TMX) and CfAgNPs-treated cells show significant morphological changes. An apoptosis study was conducted using 4',6-diamidino-2-phenylindole (DAPI) staining, in which CfAgNP-treated MCF-7 cells generated bright blue fluorescence and shortened, disjointed chromatin was evident; control cells displayed less bright fluorescence. Flow cytometry analysis revealed that the percentage of cells in late apoptosis was high following treatment with TMX (77.2%) and CfAgNP (74.6%). A novel anti-cancer agent, developed by generating silver nanoparticles from C. fulvescens extract, showed strong cytotoxic activity against MCF-7 cells.The progress of nanoparticles production by eco-friendly route, with desirable chemical and physical characteristics, and their application in helpful fields is still under investigation. Therefore, this study aimed at biosynthesis, characterization, and biomedical applications of silver nanoparticles (AgNPs) using yeasts metabolite. The yeast strains, Pichia kudriavzeviiHA-NY2 and Saccharomyces uvarumHA-NY3, were used for extracellular biosynthesis of AgNPsK and AgNPsU, respectively. AgNPs were characterized by UV-visible spectrophotometry, transmission electron microscopy (TEM), Fourier Transformed Infrared (FTIR) spectrum and dynamic light scatter (DLS). TEM image showed well dispersed round and cubic regular particles with size ranges of 12.4 ± 6.02 nm for AgNPsU and 20.655 ± 9.48 nm for AgNPsK. According to DLS analysis, the mean size diameters of AgNPsU and AgNPsK were 20.3-21.5 and 29.6-30.14 nm, respectively. Tat-BECN1 clinical trial AgNPs showed highly significant inhibitory activity against gram-positive bacteria (Bacillus subtilis ATCC6633 and Staphylococcus aureus ATCC29213), gram-negative bacteria (Pseudomonas aeruginosa ATCC27953), Candida tropicalis ATCC750, and Fusarium oxysporium NRC21. The anti-inflammatory activity of AgNPs revealed that paw edema was inhibited by the oral administration of the two biosynthesized silver-nanoparticles. In addition, they showed carrageenan activity nearest to indomethacin. All fabricated AgNPs showed a significant analgesic effect after one hour of administration, which was comparable to aspirin. Further, both AgNPsK and AgNPsU demonstrated a significant anticancer activity against HCT-116 (Colon cell line) with IC50 values 0.29, 0.24 µg ml-1, respectively, and PC3 (Prostate cell line) with IC50 values 0.57, 0.50 µg ml-1, respectively. No ulcerogenic effects of AgNPs were detected on the rats' stomach and it was safe on the gastric profile.Arbuscular mycorrhizal fungi (AMF) colonize the roots of numerous aquatic and wetland plants, but the establishment and functioning of mycorrhizal symbiosis in submerged habitats have received only little attention. Three pot experiments were conducted to study the interaction of isoetid plants with native AMF. In the first experiment, arbuscular mycorrhizal (AM) symbiosis did not establish in roots of Isoëtes echinospora and I. lacustris, while Littorella uniflora roots were highly colonized. Shoot and root biomass of L. uniflora were, however, not affected by AMF inoculation, and only one of nine AMF isolates significantly increased shoot P concentration. In the second experiment, we compared colonization by three Glomus tetrastratosum isolates of different cultivation history and origin (aquatic versus terrestrial) and their effects on L. uniflora growth and phosphorus nutrition under submerged versus terrestrial conditions. The submerged cultivation considerably slowed, but did not inhibit mycorrhizal root colonization, regardless of isolate identity. Inoculation with any AMF isolate improved plant growth and P uptake under terrestrial, but not submerged conditions. In the final experiment, we compared the communities of AMF established in two cultivation regimes of trap cultures with lake sediments, either submerged on L. uniflora or terrestrial on Zea mays. After 2-year cultivation, we did not detect a significant effect of cultivation regime on AMF community composition. In summary, although submerged conditions do not preclude the development of functional AM symbiosis, the contribution of these symbiotic fungi to the fitness of their hosts seems to be considerably less than under terrestrial conditions.Immune checkpoint inhibitor (ICI) therapies, including the programmed cell death protein 1 (PD-1) axis blockade, are considered a major oncological breakthrough of the early twenty-first century and have led to remarkable response rates and survival in a subset of patients with non-small cell lung cancer (NSCLC). However, the available therapies work only for one in five unselected, advanced NSCLC patients; thus, patient selection needs to be performed with the use of efficient biomarkers. Although imperfect, programmed death-ligand 1 (PD-L1) expression by immunohistochemistry (IHC) on tumor cells and/or immune cells has been established as a predictive biomarker for response to the PD-1 axis blockade. There remain several pre-analytical, analytical, and post-analytical issues, however, before implementing a PD-L1 IHC assay(s) in the pathology laboratory. In addition, given the lack of robust sensitivity and specificity of PD-L1 IHC for predicting response to ICIs, other biomarkers including tumor mutation burden (TMB) are under investigation. In this review, issues associated with PD-L1 IHC and TMB estimations will be discussed, and other promising biomarkers for predicting response to ICIs will be briefly introduced.

The application of the anatomical parameters of the contralateral hip joint to guide the preoperative template of the affected side relies on the bilateral hip symmetry. We investigated the bilateral hip symmetry and range of anatomical variations by measurement and comparison of bilateral hip anatomical parameters.

This study included 224 patients (448 hips) who were diagnosed with osteoarthritis (OA) and avascular necrosis (AVN) of the femur head, and underwent bilateral primary total hip arthroplasty (THA) in our hospital from January 2012 to August 2020. Imaging data included 224 patients X-ray and 30 CT data at the end of the cohort. Anatomical parameters, including the acetabular abduction angle and trochanteric height, were measured using the Noble method. Postoperative measurements included stem size, difference of leg length and offset.

Except for the isthmus width, there were no significant differences in the anatomical morphology of the hip joint. Among the demographic factors, there was a correlation between body weight and NSA.
