        Transcarotid Mechanical Thrombectomy for Embolic Intracranial Large Vessel Occlusion after Endovascular Deconstructice Embolization for Carotid Blowout Syndrome

        Lu Chi-Ju,Lin Yen-Heng,Lee Chung-Wei 대한신경중재치료의학회 2020 Neurointervention Vol.15 No.1

        Carotid blowout syndrome (CBS) is a fatal complication of head and neck cancer. Endovascular treatment, particularly deconstructive embolization, is effective for CBS, but it might result in thromboembolic events. We report the case of a 57-year-old man with underlying recurrent head and neck cancer who had CBS. The patient received endovascular embolization of the right internal, external, and common carotid arteries. Right internal carotid artery to middle cerebral artery embolic occlusion was noted immediately after the procedure, and left-sided weakness and facial palsy were found. Ipsilateral suprabulbar cervical internal carotid artery puncture was performed under fluoroscopic guidance, and rescue suction thrombectomy was successful. The patient had no significant neurological sequela. Transcarotid intraarterial thrombectomy is a reasonable method for managing postembolization large vessel occlusion, even in the neck, after irradiation.

        Over-expression of Chinese cabbage calreticulin 1b, BrCRT1b, induces initiation of organogenesis in Arabidopsis

        Zheng Lu Jin,Sun Hwa Ryu,Joon Ki Hong,Chi Eun Song,Chan Ju Lim,Young Ju Choi,Kyun Oh Lee,Woo Sik Chung,Sang Yeol Lee,Chae Oh Lim 한국유전학회 2007 Genes & Genomics Vol.29 No.3

        Calreticulin (CRT) is a major Ca2+-binding/buffering protein in the lumen of the endoplasmic reticulum. A cDNA encoding CRT, BrCRT1b (Brassica rapa CRT1b), has been isolated from Chinese cabbage flower bud. Recombinant BrCRT1b21-418 protein showed 45Ca2+-binding and chaperone activity. BrCRT1b transcripts accumulated to high levels in the root, young leaf and flower. Constitutive over-expression of BrCRT1b promoted robust shoot production and root formation at sub-optimal concentrations of auxin/cytokinin. In spite of enhanced regeneration in tissue culture, the seedling and plant growth rates were slightly inhibited in soil. Thus, our findings suggest that BrCRT1b is related to organogenesis during in vitro culture.

        Biochemical Compositions of Follicular Fluid and the Effects of Culture Conditions on the In Vitro Development of Pig Oocytes

        Huang, Wei-Tung,Lu, She-Ghi,Tang, Pin-Chi,Wu, Shinn-Chih,Cheng, San-Pao,Ju, Jyh-Cherng Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.10

        The aims of this study were, firstly, to analyze the biochemical compositions of serum and follicular fluid (FF) from prepubertal gilts after PMSG (1,000 IU) treatment. The concentrations of total proteins, lipids, cholesterol, glucose and sex hormones (progesterone, $P_4$; estradiol-$17{\beta}$, $E_2$; testosterone, T) were measured. Secondary, the effects of porcine FF (pFF) addition (40% and 100%) in IVM media and different culture conditions [Exp. 1: mBMOC-2+20% porcine serum (PS), fresh IVM medium, filtered IVMconditioned medium, or rabbit oviducts; Exp. 2: mBMOC-2+20%PS or stepwise medium replacement procedures (SMRP) cocultured with or without cumulus cells] on the in vitro development (IVD) of porcine oocytes were also examined. Results showed that no significant differences were found in total protein levels between serum and pFF from different sizes (large, >7 mm; medium, ~5-7 mm; small, <3-5 mm) of follicles (75-85 and 49-90 mg/dl; p>0.05). Total lipid concentrations remained constant in serum (395-472 mg/dl), and reduced significantly in the pFF from large follicles (287 mg/dl) at 132 h after PMSG treatment when compared to those at other time points (441-480 mg/dl). Basal cholesterol levels in serum and pFF at 12 h were similar (153-161 mg/dl), but increased at 36 h (186-197 mg/dl). Basal P4 and E2 levels in serum (0.1 ng/ml and 5.5 pg/ml) were low, but increased from 0.34 ng/ml and 12.13 pg/ml at 24 h to 0.81 ng/ml and 61.70 pg/ml at 98 h, respectively, after PMSG treatment (p<0.05). P4 levels increased linearly in pFF from large follicles during 12 through 132 h (138-1,288 ng/ml). A similar increase was also observed in $E_2$ levels (22-730 pg/ml) before 60 h post PMSG treatment, and then dropped afterwards (730-121 pg/ml). The development of the oocytes fertilized in 40% pFF-medium was greater than that in 100% pFF-medium group without gonaodtropin addition (31% vs 10%, p<0.05). However, both were lower than those in mBMOC-2+20%PS and in rabbit oviducts (p<0.05). When cocultured with cumulus cell monolayers, a greater cleavage rate was observed in the group cultured in filtered IVM-conditioned medium than the SMRP group (36% vs 18%, p<0.05). A similar phenomenon was also observed in the culture without cumulus cell monolayers (33% vs 19%, p<0.05). It is concluded that neither the fresh IVM nor filtered IVM-conditioned medium has positive effect on the IVD of oocytes. Coculture with cumulus cell monolayers and the SMRP were not beneficial to the development of IVF pig oocytes.
