In this study, we investigated the effects of one-month exposure to a 220 MHz RF field at two different average power densities (50 W/m2 and 100 W/m2) on the sperm quality in male adult Sprague-Dawley (SD) rats. Sperm quality was evaluated by measuring the number, the abnormality and the survival rate of sperm. The morphology of testis was examined by hematoxylin-eosin (HE) staining. Levels of secreting factors by Sertoli cells (including glial cell line-derived neurotrophic factor (GDNF), stem cell factor (SCF), transferrin (TRF) and androgen binding protein (ABP)) and factor by Leydig cells (testosterone, T) were determined by enzyme linked immunosorbent assay (ELISA). The expression levels of the apoptosis-related protein (Caspase 3, BAX and BCL 2) in testis were assessed by Western Blotting analysis. Compared with the sham group, the sperm quality in RF groups decreased significantly in a dose-dependent manner. Levels of GDNF, SCF, TRF and ABP in testis as well as the morphology of testis, showed on obvious changes after RF exposure. The level of serum T decreased significantly in the rats treated with 50 W/m2 RF exposure and increased significantly in the rats treated with 100 W/m2 RF exposure, compared with sham group. In addition, the protein levels of Caspase 3 and the BAX/BCL 2 ratio in testis increased obviously after RF exposure, compared with sham group. These data collectively suggested that under the present experimental conditions, 220 MHz RF exposure could affect sperm quality in rats, and the disruption of secreting function of Leydig cells and increased apoptosis of testis cells induced by RF field might both account for this damaging effect.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130713883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the adoption of cavity resonators, high unloaded quality factor (Q) and low insertion loss can be obtained. To reduce the vertical height of proposed filter, circular disk capacitive loading on open-end of the resonant rod in the coaxial cavity has been adopted. Besides, by exploiting a type of cross arrangement between the resonators, miniaturization can be further attained. Based on cavity filter design method and cross-coupling theory, two transmission zeros on both sides of the passband are synthesized by introducing capacitive and inductive cross-coupling into cascaded triplet sections. In addition, to adjust center frequency and bandwidth, tuning screws are inserted to the inner conductor of the coaxial cavities. For demonstration, a prototype of filter centered at 3.5 GHz with a bandwidth of 200 MHz is designed and simulated. Results show that the coaxial cavity bandpass filter not only exhibits a sharp roll-off with two transmission zeros located at 3.25 and 3.7 GHz, but also low insertion loss less than 0.09 dB. The overall size of the cavity was $0.2boldsymbol{lambda}_{0}times 0.35boldsymbol{lambda}_{0}times 0.17boldsymbol{lambda}_{0}$, which is more compact in comparison to the conventional fifth order coaxial cavity filters.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"9 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132033976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bio-scientists have been investigating the functional outcomes of dead cells through three classical directions, including morphological manifestations, biochemical features, and biophysical considerations. Usually, only one or two characteristics from one of these directions can be studied in a single experimental setup, providing a narrow view on the complex cell death process. We present here a new technology that could collect 84 kinds of characteristics of cells simultaneously from all of the three classical directions in a single experimental system. The technology essentially combines the method of manipulating individual cells using optically induced electrokinetics (OEK) and analysis of experimental data using data mining techniques. Using this technology, we have revealed a broader connection between the cell variability and its morphological, biophysical, and biochemical manifestations. Unlike other detection methods [1]–[5], as shown in the Supporting Table, our method can be used to quantify many parameters and recognize the living states of 20,000 cells per hour.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127252202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
