The nearly isogenic nature of the introgression lines (ILs) provides a relative advantage over other segregating populations in therapid implementation of pyramiding approach through crosses and marker analysis. A set of 126 ILs carrying various introgressedsegments from a presumed wild progenitor, Oryza rufipogon Griff. Acc. W1944 in the background of an elite Korea japonica cultivar(O. sativa L.), Hwayeongbyeo, was constructed using the marker assisted selection (MAS) technique combined with repeatedbackcrosses. The 126 ILs have different W1944 segments on each chromosome, with 100% coverage of wild segments on chromosome1, while for chromosome 10, the coverage was only 33.3%. The mean number of homozygous and heterozygous donor segmentswere 3 (ranging from 0 to 7) and 4.7 (ranging from 1 to 14.5), respectively, and 31.6% of introgressed segments had sizes ofless than 10.5 cM. A total of 41 quantitative trait loci (QTLs) and two loci associated with pericarp coloration were identified. Thenumber of QTLs per trait ranged from 2 to 6. Phenotypic variance associated with each QTL varied from 9.1 to 52.2%, with an averageof 17.1%. For 11 (26.8%) of the QTLs detected in this study, the O. rufipogon-derived alleles contributed the desired agronomiceffect despite the overall inferior characteristics of the wild phenotype. Favorable alleles from the O. rufipogon accession were identifiedfor panicle number, panicle length, days to heading, secondary branches, spikelets per panicle, and 1,000-grain weight.

Purpose: The aim of this study was to investigate the efficacy of autologous platelet-rich plasma (PRP) in the treatment of stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) refractory to medical treatment. Methods: Thirty-five patients with SUI due to urodynamically proven ISD were prospectively enrolled. Five milliliters of PRP (2.5–5 times the platelet concentration in peripheral blood) was injected into the external sphincter at 5 sites; all patients received 4 injections at monthly intervals. The primary end-point was the change in SUI severity as assessed by a visual analogue scale (VAS of SUI). The secondary-endpoints were the Global Response Assessment score and changes in urodynamic parameters from baseline to 3 months after treatment. Results: The mean age of patients was 68.7±12 years; the median duration of SUI was 4 years. Five patients had neurogenic SUI, while 30 had nonneurogenic SUI (21 with postprostatectomy incontinence, 6 with previous radical cystectomy, and 3 with other etiologies). Complete dryness was achieved in 7 patients (20.0%) while moderate improvement was observed in 14 (40.0%). The mean VAS of SUI score decreased significantly from 6.57±1.89 to 3.77±2.41 after treatment. The abdominal leak point pressure (ALPP) increased significantly from 98.3±55.8 to 157.3±79.3 cm H2O. There was no increase of ALPP in neurogenic SUI and less increase of ALPP in patients with failed treatment outcomes. No perioperative adverse events or severe complications occurred. Conclusions: Urethral PRP injection is safe and effective in increasing urethral resistance and improving SUI. PRP could be an alternative treatment modality for male and female patients with moderate SUI due to nonneurogenic causes.

Background: Ginsenoside Rg3(S) and compound K (C-K) are pharmacologically active components of ginseng that promote human health and improve quality of life. The aim of this study was to produce Rg3(S) and C-K from ginseng extract using recombinant Lactococcus lactis. Methods: L. lactis subsp. cremoris NZ9000 (L. lactis NZ9000), which harbors ${\beta}$-glucosidase genes (BglPm and BglBX10) from Paenibacillus mucilaginosus and Flavobacterium johnsoniae, respectively, was reacted with ginseng extract (protopanaxadiol-type ginsenoside mixture). Results: Crude enzyme activity of BglBX10 values comprised 0.001 unit/mL and 0.003 unit/mL in uninduced and induced preparations, respectively. When whole cells of L. lactis harboring pNZBglBX10 were treated with ginseng extract, after permeabilization of cells by xylene, Rb1 and Rd were converted into Rg3(S) with a conversion yield of 61%. C-K was also produced by sequential reactions of the permeabilized cells harboring each pNZBgl and pNZBglBX10, resulting in a 70% maximum conversion yield. Conclusion: This study demonstrates that the lactic acid bacteria having specific ${\beta}$-glucosidase activity can be used to enhance the health benefits of Panax ginseng in either fermented foods or bioconversion processes.

Titanium dioxide thin films with silver dopant (Ag-TiO2) were successfully prepared on glass substrates using the thermaloxidation method. Ag-doped titanium films were prepared using direct current (DC) and radio frequency (RF) magnetron cosputteringsystems. The thermal oxidation temperature and Ag content effects on the phase evolution, microstructure, andphoto catalytic activity of TiO2 film were studied. The crystalline structures and photo catalytic activity of the annealed AgdopedTiO2 films were methodically investigated using transmission electron microscopy (TEM), field emission scanningelectron microscopy (FESEM), X-ray diffraction (XRD), and ultraviolet spectrophotometry. The results exhibited that thethermal oxidation process at 550 oC clearly caused rutile phase formation in the 2.7% Ag-doped TiO2 films directly affectingthe photo catalytic activity. The Ag-doped TiO2 films showed good photo catalytic activity under UV-light radiation, with 59%methylene blue dye degradation rate.

Purpose: COVID pandemic significantly affected the delivery and maintenance of healthcare system, resulting in greater utilization of digital health interventions. Materials and Methods: This multi-national cross-sectional survey was administered to clinicians working in major Asia-Pacific cities during the mandatory social lockdown period in June 2020. Clinical demographics and professional data, delivery of Andrology-related healthcare services, and patient distress based on validated questionnaires such as Depression and Anxiety Stress Scales (DASS) and Decisional Engagement Scale (DES) were collected. Results: Telehealth medicine was instituted in all the centres with the majority of centres (92.9%) reported a 50% or more reduction in out-patient related services. The numbers of phone calls, emails correspondence and educational webinars have significantly increased. Despite the provision of reasons for changes in healthcare service and delay in surgery, more than half of the patients (57.1%) rated 2 on the DASS score for the item on patients over-react to situations, while a third of the patients (35.7%) scored a 2 for DASS item on patients being more demanding or unreasonable. The DES scores were more positive with most patients reported a score above 7 out of 10 in terms of items on accepting current arrangement (85.7%), confident in clinician decision-making about treatment (92.9%) and comfortable that the decision is consistent with their preferences (71.4%). Most patients (85.7%) indicated their preferences for more detailed information on healthcare provision. Conclusions: Our study showed telehealth services were integrated early and successfully during the COVID pandemic and patients were generally receptive with minimal psychosocial distress.

Objective: To quantitatively assess the pulmonary vasculature using non-contrast computed tomography (CT) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) pre- and post-treatment and correlate CT-based parameters with right heart catheterization (RHC) hemodynamic and clinical parameters. Materials and Methods: A total of 30 patients with CTEPH (mean age, 57.9 years; 53% female) who received multimodal treatment, including riociguat for ≥ 16 weeks with or without balloon pulmonary angioplasty and underwent both non-contrast CT for pulmonary vasculature analysis and RHC pre- and post-treatment were included. The radiographic analysis included subpleural perfusion parameters, including blood volume in small vessels with a cross-sectional area ≤ 5 mm<sup>2</sup> (BV5) and total blood vessel volume (TBV) in the lungs. The RHC parameters included mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), and cardiac index (CI). Clinical parameters included the World Health Organization (WHO) functional class and 6-minute walking distance (6MWD). Results: The number, area, and density of the subpleural small vessels increased after treatment by 35.7% (P < 0.001), 13.3% (P = 0.028), and 39.3% (P < 0.001), respectively. The blood volume shifted from larger to smaller vessels, as indicated by an 11.3% increase in the BV5/TBV ratio (P = 0.042). The BV5/TBV ratio was negatively correlated with PVR (r = -0.26; P = 0.035) and positively correlated with CI (r = 0.33; P = 0.009). The percent change across treatment in the BV5/TBV ratio correlated with the percent change in mPAP (r = -0.56; P = 0.001), PVR (r = -0.64; P < 0.001), and CI (r = 0.28; P = 0.049). Furthermore, the BV5/TBV ratio was inversely associated with the WHO functional classes I-IV (P = 0.004) and positively associated with 6MWD (P = 0.013). Conclusion: Non-contrast CT measures could quantitatively assess changes in the pulmonary vasculature in response to treatment and were correlated with hemodynamic and clinical parameters.
