We retrospectively reviewed and compared the results of corporal plication procedures for the correction of congenital penile curvature (CPC) between pre-pubertal and post-pubertal boys and find whether age matters in the success rates. We reviewed the records of 32 patients with CPC without hypospadias treated by simple plication near the 12 o’clock position between 1998 and 2018 in our clinic. ART0380 inhibitor Patients under 13 years of age and not had puberty yet were accepted as pre-pubertal. Residual curvature less than 10° during follow-up was accepted as a surgical success. The mean age of the pre-pubertal group was 8.3 (2-12) years, while 16.2 (14-21) for the post-pubertal patients. The mean follow-up was 38.7 (24-154) months in the pre-pubertal group and 45.1 (23-150) months in the post-pubertal group. The success rates of corporal plication in pre-pubertal and post-pubertal groups were 78% and 83% respectively (p = .753). The success rates of corporal plication were similar between pre-pubertal and post-pubertal boys. However, as the series was small further studies should be favoured to determine the effect of age on success rates.Since the outbreak of the novel coronavirus (COVID-19) pandemic, reports of xenophobic and racist incidents directed at Chinese Americans have escalated. The present study adds further understanding to potential psychosocial effects of the COVID-19 pandemic by comparing self-reported questionnaire data from two groups of Chinese students attending a public university in western United States the group who participated in the study before the outbreak of COVID-19 (Pre-COVID, N = 134), and the group who participated at the beginning (during-COVID, N = 64). The aim of the study was to (a) compare mean differences in perceived discrimination and anxiety between the two groups, (b) test whether COVID-19 moderated the link between perceived discrimination and anxiety, and (c) examine whether media exposure portraying Chinese individuals negatively mediated relations between COVID-19 and discrimination. Results showed that the During-COVID group reported higher perceived discrimination and anxiety than the Pre-COVID group. The link between perceived discrimination and anxiety was stronger for the During-COVID group. Mediation analyses suggested that negative Chinese media exposure partly accounted for the group difference in perceived discrimination. Results suggest that future studies on the psychosocial implications of the COVID-19 pandemic should consider the role of discrimination in understanding the mental health of Chinese American college students.Peptidoglycan recognition proteins (PGRPs) are well known for their abilities to recognize or hydrolyze peptidoglycan (PGN), one of the major bacterial cell wall components. However, much less is known about their antifungal activities. PGRP-S1 was previously identified from a crop pest, Mythimna separata (Walker) (Lepidoptera Noctuidae). PGRP-S1 showed bacteriolytic activities against Gram-positive and Gram-negative bacteria. In this study, tissue expression analysis showed that PGRP-S1 was mainly expressed in the midgut of naïve larvae. The induction analysis showed that it was significantly induced in the larval midgut 12 h post the injection of Beauveria bassiana conidia. To identify the key residues that are related to its microbicidal activities, the structure of PGPR-S1 was predicted for structural comparison and molecular docking analysis. Six residues (H61, H62, Y97, H171, T175, and C179) were mutated to Ala individually by site-directed mutagenesis. The recombinant wild-type (WT) and mutant proteins were expressed and purified. The recombinant proteins bound to different polysaccharides, PGNs, and bacteria. H61A, Y97A, H171A, and C179A lost amidase activity. Accordingly, antibacterial assay and scanning electron microscopy confirmed that only H62A and T175A retained bacteriolytic activities. The germination of B. bassiana conidia was significantly inhibited by WT, H61A, Y97A, T175A, and C179A mutants. Electron microscopy showed that some conidia became ruptured after treatment. The growth of hyphae was inhibited by the WT, H61A, H62A, and T175A. In summary, our data showed that different residues of PGRP-S1 are involved in the antibacterial and antifungal activities.The buried or hidden penis in adults is troublesome in males, whereas the length of the penile shaft is buried under the skin surface of the suprapubic fat to a degree that reveals the concept of a little penis. We aimed to assess a new modality of treatment to increase the apparent penile length by using the cryolipolysis in the reduction of male suprapubic fat as a noninvasive procedure. This prospective study was performed on 46 male patients complaining of buried short apparent small size penis. All patients were subjected to full medical history, body mass index and examination of penile (length, size and abnormalities). The measures of the apparent penile length from the skin to the tip of the glans penis and suprapubic skin fold thickness using (adipometer) were recorded before the three consecutive suprapubic cryolipolysis sessions. The mean apparent stretched penile length at session 1, 2 and 3 were 12.1 ± 0.5 cm, 12.66 ± 0.48 and 12.88 ± 0.72, respectively, with a statistically significant increase between three sessions (p less then .001), whereas the mean skin fold suprapubic fat at session 1, 2 and 3 was 2.99 ± 0.49 cm, 2.37 ± 0.48 and 2 ± 0.37, respectively, with a statistically significant decrease (p less then .001). The cryolipolysis of suprapubic fat is a safe, effective, noninvasive and applicable procedure that successfully decreases the suprapubic fat in males and increases the apparent length of the buried penises.
Rice grains can be contaminated easily by certain fungi during storage and in the market chain, thus generating a risk for humans. Most classical methods for identifying and rectifying this problem are complex and time-consuming for manufacturers and consumers. However, E-nose technology provides analytical information in a non-destructive and environmentally friendly manner. Two-feature fusion data combined with chemometrics were employed for the determination of Aspergillus spp. contamination in milled rice.
Linear discriminant analysis (LDA) indicated that the efficiency of fusion signals (’80
s values’ and ‘area values’) outperformed that of independent E-nose signals. Linear discriminant analysis showed clear discrimination of fungal species in stored milled rice for four groups on day 2, and the discrimination accuracy reached 92.86% by using an extreme learning machine (ELM). Gas chromatography-mass spectrometry (GC-MS) analysis showed that the volatile compounds had close relationships with fungal species in rice.
