“…Proses sonikasi diterapkan dalam farmasi, makanan, kosmetik, air, pelapis, tinta, cat, pengerjaan logam, perawatan kayu, pengerjaan logam(37), nanokomposit, pestisida, bahan bakar, produk kayu dan banyak industri lainnya. Sonikasi juga dapat digunakan untuk mempercepat pembubaran, dengan cara memecah interaksi antarmolekul serta menganalisis dinamika molekular dan kinetika reaksi pada pembelahan molekul (38).Ini sangat berguna ketika tidak memungkinkan untuk mengaduk sampel, seperti tabung NMRdan juga dapat digunakan sebagai penyedia energi (39) [19] , 2012-2016 oksidasi [20] 2017-2018 sonochemic al [21] , PCR [22] 2019> langsung (AS) [16] , Depolimerisasi [17] , Degradasi [18] , Tes triple negative praktis tidak termasuk PJI(64).…”

Sonikasi merupakan teknologi yang memanfaatkan gelombang ultrasonik. Ultrasonik adalah suara atau getaran dengan frekuensi yang terlalu tinggi untuk bisa didengar oleh manusia, yaitu kira-kira di atas 20 kHz. Review ini bertujuan untuk mengetahui pemanfaatan teknologi sonikasi dalam berbagai bidang. Hasil menunjukkan bahwa teknologi telah digunakan pada berbagai bidang seperti:industri, kesehatan, biologi, kimia, dan fisika.

“…We can observe the cross sections of the cerebellum, lateral ventricle, and thalamus to determine whether there is an abnormal intracranial structure. However, the diagnostic accuracy of conventional two-dimensional ultrasonography is still insufficient to meet the clinical expectations and actual needs[ 4 , 5 ].…”

BACKGROUND Prenatal examination is an important measure for the screening and diagnosis of fetal malformations. AIM To investigate the accuracy of ultrasonography in the diagnosis of fetal central nervous system (CNS) malformations. METHODS One hundred and thirteen pregnant women suspected of having fetal CNS malformations were examined at our hospital from December 2018 to October 2020 using two-dimensional ultrasonography and three-dimensional ultrasonography, respectively. RESULTS According to the pathological results, there were 79 cases of CNS malformations and 34 cases of non-CNS malformations among the 113 pregnant women suspected of having fetal CNS malformation. Fifty-one cases of CNS malformation and 26 cases of non-CNS malformation were detected by two-dimensional ultrasonography, and 73 cases of CNS malformation and 30 cases of non-CNS malformation were detected by three-dimensional ultrasonography. The diagnostic sensitivity (92.41%) and accuracy (91.15%) of three-dimensional ultrasonography were higher than those of two-dimensional ultrasonography (64.56% and 68.14%, respectively) ( P = 0.000). The specificity of three-dimensional ultrasonography (88.24%) was higher than that of two-dimensional ultrasonography (76.47%); however, the difference was not significant ( P = 0.203). CONCLUSION Three-dimensional ultrasonography has high application value in the diagnosis of fetal CNS malformations. In addition, the image quality is clear, and the diagnostic sensitivity and accuracy are high.

“…In particular, identification of an abnormal vermis size is a critical component in the diagnosis of vermis hypoplasia, which can occur as an isolated lesion or accompany Dandy Walker malformation 2 and many other syndromes. However, a number of published nomograms for vermis size as well as techniques for measurement are described in the literature 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 . Many of these studies are flawed by small sample size or unclear measurement techniques.…”

Purpose To conduct a systematic review and meta-analysis of published nomograms for fetal vermis biometry. Materials and Methods A structured literature search was conducted to identify studies that reported normal measurements of the fetal vermis. A customized quality assessment tool was used to review the selected articles. Random effects meta-analysis was used to calculate normal ranges for vermian craniocaudal diameter, anteroposterior diameter, and surface area. Results A total of 21 studies were included for qualitative review and 3 studies were included for quantitative synthesis. The 3 included articles comprised a total of 10 910 measurements from gestational ages 17–35 weeks. The quality assessment demonstrated that there was generally poor reporting regarding maternal characteristics and neonatal outcomes. Except for one article with a large sample size, the mean number of fetuses per week of gestational age was 15.9, with the lowest number being 5. There was significant statistical heterogeneity. Non-visualization rates ranged from 0–35.4 %. The craniocaudal diameter (reported in 3 articles) increased from a mean of 7.90 mm (95 % confidence interval [CI] 7.42, 8.38) at 17 weeks to 21.90 mm (95 % CI 20.63, 23.16) at 35 weeks gestation. The anteroposterior diameter (reported in 2 articles) increased from 6.30 mm (95 % CI 5.42, 7.18) at 17 weeks to 15.85 (95 %CI 15.49, 16.21) at 32 weeks. Conclusion Reference ranges for vermis biometry across gestation based on meta-analysis of existing references are provided. However, because many of the underlying studies suffered from significant methodological issues, the ranges should be used with caution.
