Association of Anemia with Neurodevelopmental Disorders in a Nationally Representative Sample of US Children.

OBJECTIVE: To examine the associations of anemia with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and learning disability in US children. STUDY DESIGN: We included children and adolescents aged 3-17 years from the National Health Interview Survey (NHIS), 1997-2018. Information about physician-diagnosed history of anemia, ASD, ADHD, and learning disability was reported by a parent or guardian. Multiple logistic regression with sample weights was used to estimate the ORs and 95% CIs of neurodevelopmental disorders according to the presence of anemia. RESULTS: Of the total population of 213 893 children aged 3-17 years (mean age [SE], 10.01 [0.01] years), 2379 were reported to have a diagnosis of anemia, for a weighted prevalence of 1.06% (95% CI, 1.01-1.12). The prevalence of ASD was 1.94% (95% CI, 1.20-2.68) among children with anemia and 1.07% (95% CI, 1.01-1.14) among those without anemia. The corresponding prevalences were 12.24% (95% CI, 10.47-14.00) and 7.73% (95% CI, 7.58-7.88) for ADHD and 15.03% (95% CI, 13.08-16.99) and 7.75% (95% CI, 7.39-7.70) for learning disability, respectively. Compared with those without anemia, children with anemia were more likely to have neurodevelopmental disorders, with an aOR of 2.07 (95% CI, 1.39-3.08) for ASD, 1.84 (95% CI, 1.55-2.19) for ADHD, and 2.22 (95% CI, 1.90-2.60) for learning disability. CONCLUSIONS: In a nationally representative sample of US children, we found significant associations between anemia and neurodevelopmental disorders including ASD, ADHD, and learning disability. Further investigation is warranted to assess the causality and elucidate the underlying mechanisms.

Minimal hydrocelectomy with the aid of scrotoscope: a ten-year experience.

BACKGROUND: Since hydrocelectomy remains the choice of surgical treatment of hydrocele and standard surgical procedures may cause postoperative discomfort and complications, a new minimal surgery procedure is needed. The scrotoscope was used for the diagnosis and treatment of intrascrotal lesions. The aim of the study is to illustrate a new minimal hydrocelectomy with the aid of scrotoscope, in an effort to decrease complications. MATERIALS AND METHODS: Between 2002 and 2012, 65 patients underwent hydrocelectomy with the aid of a scrotoscope. Before carrying out hydrocelectomy, the scrotoscopy was first used to examine the intrascrotal contents to exclude any pathological lesions. After determining the condition of testis, epididymis and spermatic cord and excluding any other secondary causes of hydrocele, a 2.0 cm scrotal incision was performed. The parietal tunica vaginalis was then grasped out of scrotum, and the mobilized tunica was excised. The scrotoscopy was then performed again to inspect the intrascrotal contents. RESULTS: Mean operative time was 35.4 minutes. No major complications occurred during the post-operative follow-up period. Of these 65 patients, 61 underwent scrotoscopy and minimal hydrocelectomy, two patients underwent open hydrocelectomy because thickening of hydrocele wall was identified; two patients with acute inflammation only underwent scrotoscopy. Pathological changes were observed among eight patients. All patients were satisfied with the outcomes. CONCLUSIONS: Minimal hydrocelectomy shows commendable results and fewer complications. The combination of minimal hydrocelectomy and scrotoscopy seems to be an encouraging technique. This novel surgical procedure proves to be a viable option for the diagnosis and treatment of hydrocele.

Growth of in vitro Fusarium oxysporum f. sp. niveum in chemically defined media amended with gallic acid.

Gallic acid was artificially added to the media to grow Fusarium oxysporum f.sp.niveum to investigate its effect on the pathogenic fungus. Results indicate that gallic acid inhibited the growth of F. oxysporum f.sp.niveum. The colony diameter, the conidia germinating rate and the conidia yield were reduced by 5.7-22.9%%, 35.8-55.6% and 38.9-62.2% respectively. However, the virulence factors by the fungus were stimulated. The activity of pectinase, proteinase and cellulase increased by 12.3-627.8%, 11.8-41.2% and 0.5-325.0% respectively, while the activity of amylase increased slightly. The results suggest that gallic acid repressed growth but facilitated the relative pathogenicity of invading pathogens.

The proapoptotic activity of C-terminal domain of apoptosis-inducing factor (AIF) is separated from its N-terminal.

Apoptosis-inducing factor (AIF) is a mitochondrial flavoprotein that mediates both NADH-oxidizing and caspase-independent apoptosis. Further, the proapoptotic activity of AIF is located in the C-terminus of AIF, although the precise minimum sequence responsible for apoptosis induction remains to be investigated. In the present study, we generated two truncated AIFs, AIFDelta1-480-FLAG, which is a FLAG-tagged C-terminal peptide comprising amino acids from 481 to 613, and AIF360-480 containing amino acids from 360 to 480 of AIF. We used confocal microscopy to demonstrate that both the truncated proteins are expressed and located in the cytoplasm of transfected cells. AIFDelta1-480 but not AIF360-480 induces apoptosis in transfected cells. We also found that the expression of AIFDelta1-480 could initiate the release of cytochrome c from the mitochondria. The suppression of caspase-9 via siRNA blocked the proapoptotic activity of AIFDelta1-480. Therefore, AIFDelta1-480 is sufficient for inducing caspase-9-dependent apoptotic signaling, probably by promoting the release of cytochrome c. At last, we generated a chimeric immuno-AIFDelta1-480 protein, which comprised an HER2 antibody, a Pseudomonas exotoxin A translocation domain and AIFDelta1-480. Human Jurkat cells transfected with the immuno-AIFDeltal-480 gene could express and secrete the chimeric protein, which selectively recognize and kill HER2-overexpressing tumor cells. Our study demonstrates the feasibility of the immuno-AIFDeltal-480 gene as a novel approach to treating HER2-overexpressing cancers.

Xylomexicanins A and B, new Delta14,15-mexicanolides from seeds of the Chinese mangrove Xylocarpus granatum.

Two new mexicanolide-type limonoids, named xylomexicanin A (1) and xylomexicanin B (2), were isolated from seeds of the Chinese mangrove Xylocarpus granatum. Their structures were elucidated on the basis of spectroscopic methods. Compound 1 exhibited antiproliferative activity against human breast carcinoma cells (KT), while 2 did not show inhibitory effects on eleven human tumour cell lines tested.
