Abstract
Observational studies on the association between citrus fruit intake and risk of renal cell carcinoma (RCC) have reported inconsistent results. We quantitatively assessed this association by conducting a meta-analysis. PubMed and Embase databases search was conducted including relevant studies published up to January, 2020. We included epidemiological studies that reported relative risks (RRs) or odds ratios (ORs) with 95% confidence intervals (CIs) for the association between citrus fruit intake and RCC risk. A total of eight epidemiological studies consisting of five cohort and three case-control studies were included. The overall analysis showed a significantly reduced risk of RCC for high intake of citrus fruit (OR = 0.84, 95% CI 0.73-0.95). No heterogeneity was detected among the included studies (p = 0.497 for heterogeneity; I2 = 0). There was no significant publication bias by Begg's test (p = 0.266) or Egger's test (P = 0.578). A statistically significant association between citrus fruit intake and RCC was observed in case-control studies (OR = 0.84, 95% CI 0.71-0.98), while no association was observed in cohort studies (OR = 0.84, 95% CI 0.64-1.05). In addition, the dose-response analysis indicated that the RCC risk reduced by 13% (95%CI 1.0%-27%, p = 0.04 for heterogeneity) for each 100 grams per day increment of citrus fruit intake. In summary, our findings suggest an inverse association between citrus fruit intake and RCC incidence.

Abstract
BACKGROUND Prostate cancer (PC) is currently the most common malignant tumor of the genitourinary system in men. Radical prostatectomy (RP) is recommended for the treatment of patients with localized PC. Adjuvant hormonal therapy (AHT) can be administered postoperatively in patients with high-risk or locally advanced PC. Chemotherapy is a vital remedy for castration-resistant prostate cancer (CRPC), and may also benefit patients with PC who have not progressed to CRPC.
CASE SUMMARY A 68-year-old male was admitted to our hospital because of urinary irritation and dysuria with increased prostate-specific antigen (PSA) levels. After detailed examination, he was diagnosed with PC and treated with laparoscopic RP on August 3, 2020. AHT using androgen deprivation therapy (ADT) was performed postoperatively because of the positive surgical margin, extracapsular extension, and neural invasion but lasted only 6 mo. Unfortunately, he was diagnosed with rectal cancer about half a year after self-cessation of AHT, and was then treated with laparoscopic radical rectal resection and adjuvant chemotherapy using the capecitabine plus oxaliplatin (CapeOx) regimen. During the entire treatment process, the patient's PSA level first declined significantly after treatment of PC with laparoscopic RP and ADT, then rebounded because of self-cessation of ADT, and finally decreased again after CapeOx chemotherapy.
CONCLUSION CapeOx chemotherapy can reduce PSA levels in patients with high-risk locally advanced PC, indicating that CapeOx may be an alternative chemotherapy regimen for PC.

Abstract
In straw return fields, nitrogen-fertilizers are added to mitigate microbial competition for nitrogen with plants. However, in arsenic (As)-contaminated paddy fields, the specific effects of different nitrogen fertilizers on As mobility after straw incorporation and the interactions among iron(Fe)/carbon(C)/nitrogen(N)/As are not well understood. In the reported microcosm experiment we monitored As-mobility as a function of different dosages of KNO3, NH4Cl and rice straw incorporation. Addition of both KNO3 and NH4Cl significantly inhibited the As mobilization induced by straw incorporation. Following the KNO3 addition, the As concentration in porewater dropped by 51-66% after 2 days of the incubation by restraining Fe reduction and enhancing Fe oxidation. High-dose NH4Cl addition reduced As in porewater by 22-43% throughout the incubation by decreasing porewater pH. High-throughput sequencing results demonstrated that KNO3 addition enriches both the denitrifying and Fe-oxidizing bacteria, while diminishing Fe-reducing bacteria; NH4Cl addition has the opposite effect on Fe-reducing bacteria. Network analysis revealed that As and Fe concentrations in porewater were positively correlated with the abundance of denitrifying and Fe-reducing bacteria. This study broadens our insight into the As biogeochemistry associated with the N/C/Fe balance in soil, which are of great significance for agronomic management and mitigation the risk of As-contaminated paddy fields.

Abstract
In this study, low-field nuclear magnetic resonance(LF-NMR) and magnetic resonance imaging(MRI) were employed to analyze the water distribution, status, and migration in the moistening process of Arecae Semen. Peleg model was adopted to study the water absorption kinetics of Arecae Semen moistened at different water temperatures(10, 30, and 50 ℃). The Arecae Semen samples soaked at different water temperatures all contained four water states: binding water T_(21), non-flowing water T_(22), free water T_(23), and unbound water T_(24). Non-flowing water had the largest increase in peak area during the moistening process, followed by free water. The peak areas of non-flowing water, free water, and total water were correlated with the water content(P<0.01). Therefore, LF-NMR can quickly and non-destructively predict the water content of Arecae Semen during moistening. The peak area of non-flowing water and the content of free water were correlated with the content of arecoline in the soaking solution(P<0.01), which indicated that the faster flow of non-flowing water and more free water corresponded to more arecoline dissolved. The MRI images showed that the water migration pathway varied at different soaking temperatures, and the moistening degree obtained by this means was consistent with that obtained based on traditional experience. The rate constant K_1 fitted by Peleg model decreased with the increase in water temperature, while the capacity constant K_2 showed an opposite trend. The Arrhenius equation fitting of K_1 with temperature showed that the activation energy of Arecae Semen in the moistening process was 32.98 kJ·mol~(-1). LF-NMR/MRI can be used to analyze the water status and content and determine the end moisturing point of Arecae Semen. Peleg model can accurately describe the water absorption properties of Arecae Semen in the moistening process. The findings of this study can guide the moistening optimization and mechanism research of other seed Chinese medicinal materials.

Abstract
INTRODUCTION Treatment options for lymph node positive prostate cancer are limited. We retrospectively compared patients who underwent external radiotherapy (ERT) to patients treated by radical prostatectomy (RPX). MATERIALS AND METHODS A total of 102 lymph node positive patients from the RPX series at Ulm University were evaluated. In all, 76 patients received adjuvant androgen withdrawal as part of their primary treatment. In the ERT group, 44 patients were treated at the University of Michigan using a fractionated regimen. Of these, 21 patients received early adjuvant hormonal therapy. Patients with neoadjuvant therapy before RPX or ERT were excluded. RESULTS In the RPX group, PSA nadir (nadir < or = 0.2 vs > 0.2 ng/ml) showed a strong association with outcome. In the ERT group, pretreatment PSA was an independent predictor of outcome (P = 0.04) and patients with adjuvant hormonal therapy had a significant longer recurrence-free interval compared to patients without adjuvant therapy (P = 0.004). Comparing only patients with adjuvant hormonal treatment after cancer-specific therapy, the ERT-treated patients had a borderline longer PSA recurrence-free survival time compared to the RPX-treated patients (P = 0.05). CONCLUSIONS In case of positive lymph nodes, RPX and ERT might be considered and need to be explained to the patient. For future treatment decisions, the presented findings and a potential survival benefit need to be evaluated in a larger prospective setting.

Abstract
We used a modification of fracture-flip to reveal the nanoanatomy of the inner surface of the plasma membrane in promastigotes of Leishmania. After freeze-fracture, lightly fixed promastigotes were coated with a stabilizing layer of carbon evaporated from an electron gun, thawed, and washed. Fractured promastigotes attached to the carbon casts by the protoplasmic (i.e., inner) halves of their plasma membranes were treated with Triton X-100, followed by exposure to low concentrations of trypsin and thorough washing. This was followed by picking up and flipping of the replicas, followed by air-drying. The actual inner surfaces of the plasma membrane were then imaged by platinum shadowing. Extended, three-dimensional, high-resolution views of the inner surface of the plasma membrane showed parallel arrays of microtubules (average spacing 47 nm) closely apposed to the inner surface. Cytochemical labeling confirmed the morphological identification of both subpellicular and flagellar microtubules, as determined by treatment with mouse monoclonal anti-alpha- or anti-beta-tubulin, followed by labeling with goat anti-mouse IgG adsorbed to colloidal gold. Removal of the microtubules revealed parallel arrays of particles (average diameter 17 nm). We hypothesize that these particles represent the cytoplasmic portion of proteins that link the microtubules to the plasma membrane.

Abstract
Heightened interest in meibomian glands dysfunction prompted the authors to examine the ultrastructure of the glandular epithelium in specimens of surgical origin, by thin section and freeze-fracture electron microscopies. In meibomian glands, the morphology and ultrastructure of acinar cells varies considerably according to their stage of holocrine differentiation. This study shows close interdependence between fat droplets and Golgi apparatus or endoplasmic reticulum. As the cells initiate their differentiation, the smooth endoplasmic reticulum and the Golgi apparatus become prominent and the first small lipid droplets appear in the cytoplasm. When fractured through a plane close to their surface, lipid droplets appear onion-like structured, ie made up of a variable number of irregular shaped concentric lamellae. This lamellar organization suggests that membranes are not only involved in synthesis, but also that some of their components are incorporated in the fat droplets. The authors conclude that human meibomian glands are a holocrine glandular complex that, despite great differences in type and location, present basic similarities with sebaceous glands.

Abstract
The product of protooncogene c-mos, pp39mos, is expressed and functions during oocyte maturation. We have previously found that pp39mos is complexed with and phosphorylates tubulin. In addition, part of pp39mos is localized on mitotic spindle and spindle pole regions in c-mosxe-transformed NIH/3T3 cells. Here, we further characterized the interaction between pp39mos and tubulin. We show that mos product synthesized in vitro appears in a 500 kD complex and can oligomerize with tubulin in vitro under tubulin polymerization conditions. Moreover, conditions which favor microtubule depolymerization facilitate pp39mos extraction from c-mosxe-transformed NIH/3T3 cells. We also show by immunofluorescence and immunoelectron microscopy that pp39mos is localized on microtubules. Thus, in vitro and in vivo the mos product is associated with tubulin and microtubules, respectively. Therefore, the mos product may be involved in the modification of microtubules and formation of the spindle.

Abstract
Freeze-fracture electron microscopy reveals that intramembrane particles are concentrated in a band encircling the posterior portion of the acrosome of Strongylocentrotus purpuratus sperm. Two colloidal gold labeling methods, label-fracture and replica-staining fracture-flip, were employed to show that the plant lectin wheat germ agglutinin, which recognizes a 210 kDa sperm surface glycoprotein, binds to this localized band of intramembrane particles. Monoclonal antibody J18/2, which also recognizes the 210 kDa surface glycoprotein, shows this localized binding in approximately 20% of the sperm observed in this study. The majority of sperm displayed a uniform distribution of receptor sites for monoclonal antibody J18/2. Since wheat germ agglutinin and monoclonal antibody J18/2 are known to agglutinate Strongylocentrotus purpuratus sperm but not sperm of another sea urchin, Lytechinus pictus, similar determinations were made for the latter species. Lytechinus pictus sperm are not labeled with wheat germ agglutinin and are only sparsely labeled with monoclonal antibody J18/2. The acrosomal localizations of wheat germ agglutinin and monoclonal antibody J18/2 receptors in Strongylocentrotus purpuratus sperm are consistent with the involvement of the 210 kDa surface glycoprotein in an egg jelly-induced sperm acrosome reaction. Low-temperature post-embed labeling of thin sections with wheat germ agglutinin and monoclonal antibody J18/2 show concentrations of label within the acrosomal vesicle of Strongylocentrotus purpuratus sperm, suggesting the presence of an intracellular storage site for the 210 kDa glycoprotein.
