Senile involution is divided into two classes : physiological senile involution and pathological senile involution. Physiological senile involution is a natural process of vital action of decreasing Vital Essence and Energy in kidney that is a necessary physiological phenomenon. Pathological senile involution is an evidence of impairment of True Qi of internal human body. Human vital action is a changing process of life, senility, sickness, and death. In other words, this is a natural process of being full and decreasing of Vital Essence and Energy in kidney, and True Qi of human body decides this process. The Vital Essence and Energy in kidney vary, and they are influenced and restricted by various elements. The time of a senile involution varies individually. Human body protects and makes efforts not to leak out True Qi in effective ways. We can postpone a limit of time of physiological senile involution phenomenon. This is called "Health Preservation" - resistance against senile involution.

This study was undertaken to determine the normal appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in 11 Korea Jin-do dogs. Serial ultrasonographic examination was done daily during the first week, 3 days interval from 8 to 30 days, and weekly from 31 to 100 days postpartum, respectively. Of 11 postpartum bitches, 10 bitches (90.9%) had normal involution and 1 bitch (9.1%) had subinvolution of the placental sites (SIPS) by gross findings, vaginal discharges, and by ultrasographic findings, uterine shape and echogenicity. The excretory period of vaginal discharges in 10 normal bitches of uterine involution was finished completely at $20.2{\pm}4.6$ days (Mean${\pm}$SD) postpartum, but in 1 SIPS at 50 days postpartum. The short axis shape of the uterus was initially often flaccid-appearing. It varied from circular to crescent shaped to polygonal. This lasted until $16.5{\pm}3.7$ days postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was created a beaded appearance of the horns until $29.9{\pm}3.2$ days postpartum. After 30 days, it was appeared as tubular shape without distinguished between placental and interplacental sites. The ultrasonographic image of the postpartum uterus consisted of four echogenicity distinct layers. Uterine wall was represented the very hyperechoic serosa, hypoechoic myometrium, hyper echoic endometrium and anechoic structures of fluid in the uterine cavity until 7 days postpartum. The individual uterine layers were most prominent during the first week postpartum, and they became progressively less distinct throughout the course of uterine involution. Anechoic structures of fluid in the uterine cavity was detected until $25.0{\pm}6.4$ days postpartum, after which time it was not reliably detected. The uterine diameter was decreased not only in the placental sites frorm $24.1{\pm}2.5mm$ at 1 day to $15.4{\pm}1.4mm$ at 7 days postpartum, but also in the interplacental sites $14.9{\pm}1.5mm$ at 1 day, $10.6{\pm}0.8mm$ at 7 days postpartum. There was a general trend of decreasing uterine diameter, which occurred more rapidly at the placental sites. At 31 days pastpartum, these diameter reached almost same size, after that time, they could be not distinguished between placental and interplacental sites. At 87 days postpartum, the uterine diameter was $5.6{\pm}0.6mm$ both placental and interplacental sites, and the uterine horns were uniform hypoechoic, tubular structures without enlargement. Therefore, complete involution of the uterus occurred at that time. It was concluded that normal postpartum uterine involution in Korea Jin-do bitches appeared to be completed around 87 days postpartum by gross findings such as vaginal discharges, and by ultrasonographic findings, uterine shape and echogenicity. Also ultrasonographic characteristics of the postpartum uterine involution were described. Therefore, these result suggest that ultrasonographic assessment is a reliable method for diagnosing the SIPS and uterine dysfunction, such as pyometra in bitch.

ON AN INVOLUTION ON PARTITIONS WITH CRANK 0

Kim, Byungchan The Youngnam Mathematical Society 2019 East Asian mathematical journal Vol.35 No.1

Kaavya introduce an involution on the set of partitions with crank 0 and studied the number of partitions of n which are invariant under Kaavya's involution. If a partition ${\lambda}$ with crank 0 is invariant under her involution, we say ${\lambda}$ is a self-conjugate partition with crank 0. We prove that the number of such partitions of n is equal to the number of partitions with rank 0 which are invariant under the usual partition conjugation. We also study arithmetic properties of such partitions and their q-theoretic implication.

The purpose of this research was to obtain the selectively genes at the involution stage of bovine mammary gland, and to know their function whether these genes induce cell apoptosis or not. The bovine involution-induced cDNAs were isolated by subtractive hybridization method. We selected involution specific clones compared with lactation-specific clones using dot blot analysis. From this method we cloned bovine glycoprotein Ⅲ(clusterin), serum amyloid A3 protein, WDNM1 protein. Three clones were further confirmed to be specifically expressed in involution stage by Northern blot analysis. And we cloned full sequence these three cDNAs. Expression vectors for these cDNA containing full-coding region were constructed into pIRES, expression vector. These expression vectors were transfected into mammary epithelial cell line, HC11 cells. The transfectants were further confirmed by RT-PCR. To further characterize regulated expression of these genes ininvitro system, we treated death inducing agents in HC11. Finally, glycoproteinⅢ, serum amyloid A3 and WDNM1 recombinant proteins were produced in E. coil using pET-expression vectors system.

NIL-CLEAN RINGS OF NILPOTENCY INDEX AT MOST TWO WITH APPLICATION TO INVOLUTION-CLEAN RINGS

Li, Yu,Quan, Xiaoshan,Xia, Guoli Korean Mathematical Society 2018 대한수학회논문집 Vol.33 No.3

A ring is nil-clean if every element is a sum of a nilpotent and an idempotent, and a ring is involution-clean if every element is a sum of an involution and an idempotent. In this paper, a description of nil-clean rings of nilpotency index at most 2 is obtained, and is applied to improve a known result on involution-clean rings.

This study was undertaken to determine the normal serial ultrasonographic appearance of the postpartum uterine involution in small pet dogs (Yorkshire terrier and Maltese). Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored by ultrasonography in 12 small pet dogs. Serial ultrasonographic examinations were done daily during the first week, 3 days interval from 8 to 30 days, and weekly from 31 to 100 days postpartum. The excretory period of vaginal discharge in 12 normal bitches of uterine involution was finished completely within 3 weeks postpartum. The short axis shape of the uterus was initially often flaccid-appearing. It varied from circular to polygonal. This lasted until 15.75$\pm$3.84 days postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was a beaded appearance until 30.89$\pm$4.25 days postpartum. After 30 days, it was appeared as tubular shape between placental and interplacental sites. The ultrasonographic image of the postpartum uterus consisted of four echogenicity distinct layers. Uterine wall was represented as very hyperechoic serosa, hypoechoic myometrium, hyperechoic endometrium and anechoic structures of fluid in the uterine cavity until 7 days postpartum. The individual uterine layers were most prominent during the first week postpartum, and they became progressively less distinct throughout the course of uterine involution. The thickness of myometrium was decreased rapidly in the placental sites from 4.47$\pm$1.42 mm at 1 day to 1.92$\pm$0.26 mm at 16 day, and in the interplacental sites from 3.19$\pm$0.61 mm at 1 day to 1.39$\pm$0.61 mm at 16 day. And it was decreased slowly until 94 day and was been minimum thickness at 94 day. The thickness of endometrium was also decreased like that of myometrium. The uterine diameter in the placental sites was decreased from 22.28$\pm$3.01 mm at 1 day to 16.11$\pm$1.46 mm at 7 day, and in the interplacental sites was decreased from 13.65$\pm$2.34 mm at 1 day to 9.41$\pm$1.59 mm at 7 day postpartum. From 7 day to 93 day, the change of diameter was more and more slow. At 94 days postpartum, the uterine diameter was 5~6 mm both placental and interplacental sites, and the uterine horns were uniform hypoechoic, tubular structures without enlargement. Therefore, complete involution of the uterus occurred at 94 days. It was concluded that normal post partum uterine involution in small pet dogs appeared to be completed 94 days postpartum by gross findings such as vaginal discharges, and by ultrasonographic findings, uterine shape and echogenicity.

On an Involution on Partitions with Crank 0

김병찬 영남수학회 2019 East Asian mathematical journal Vol.35 No.1

Kaavya introduce an involution on the set of partitions with crank 0 and studied the number of partitions of n which are invariant under Kaavya’s involution. If a partition λ with crank 0 is invariant under her involution, we say λ is a self- conjugate partition with crank 0. We prove that the number of such partitions of n is equal to the number of partitions with rank 0 which are invariant under the usual partition conjugation. We also study arithmetic properties of such partitions and their q-theoretic implication.

The main objective of this paper is to improve the above mentioned result without the condition of the second kind involution. Moreover, a related result has been discussed.

SOME STUDIES ON JORDAN (𝛼, 1)^* -BIDERIVATION IN RINGS WITH INVOLUTION

SK. HASEENA,C. JAYA SUBBA REDDY The Korean Society for Computational and Applied M 2024 Journal of applied and pure mathematics Vol.6 No.1

Let R be a ring with involution. In the present paper, we characterize biadditive mappings which satisfies some functional identities related to symmetric Jordan (𝛼, 1)^*-biderivation of prime rings with involution. In particular, we prove that on a 2-torsion free prime ring with involution, every symmetric Jordan triple (𝛼, 1)^*-biderivation is a symmetric Jordan (𝛼, 1)^*-biderivation.

Liaqat Ali,Muhammad Aslam,Mawahib Elamin,Huda Uones Mohamed Ahamd,Newma Yahia,Laxmi Rathour 한국전산응용수학회 2024 Journal of applied mathematics & informatics Vol.42 No.2

In this research article, we study a class of semirings with involution. Differential identities involving two or three derivations of a semiring with second kind involution are investigated. It is analyzed that how these identities, with a special role for second kind involution, bring commutativity to semirings.
