This paper deals with latchup effect in CMOS retrograde well, focusing on their dependence on I/I energy conditions, so we derived some latchup characteristics from simulation for different I/I conditions on implantation energies which were used in process simulation. From these results, we could understand the dependency of CMOS retrograde well latchup on I/I energy condition.

Retrograde ejaculation is a condition that causes male infertility. Infertiltiy treatment is usually based on assisted reproductive technology with the use of sperms recovered from the bladder after ejaculation. Many pregnancies have been tried by artificial intrauterine insemination with the husband's sperm recovered from voided urine. In this case, ovulation was induced by clomiphene citrate and human menopausal gonadotropin, pH and osmorality of urine was controlled by modified Ham's F-10 contained 10% serum substitute supplement and immediately semen collection, to improve sperm motility. We had experienced a successful pregnancy case by above method, and reported with brief review of literature as well.

The properties of ideal retrograde filling materials include the ability to seal the root canal system in three dimensions and well tolerated by periradicular tissues. Biocompatibility testing has been done mainly with cytotoxicity tests using cell culture. Little attention has been paid to the potential adverse influence on the inflammatory and immune reaction in the periapical tissue. The purpose of this study was to investigate the effects of retrograde filling materials on human mononuclear cells in vitro. Freshly mixed and set specimens from six materials (Z100, Tetric Ceram, Fuji II, Fuji II LC, F2000, Compoglass Flow, and ZOE) were eluated with cell culture medium for 24 hours. Cytotoxic effects of these extracts were evaluated by determining cell viability and enzyme activity using MTT and lactate dehydrogenase (LD). The production of inflammatoy bone resorptive cytokine, TNF-${\alpha}$ was measured from human peripheral blood mononuclear cells (PBMC) exposed to the extracts by means of Endogen Human TNF-${\alpha}$ ELISA kit (Wobrun, MA, U.S.A.). Eluates and diluted (1 : 10) eluates with cell culture medium from freshly mixed Fuji IT had cytotoxic effects on mononuclear cells using MTT and LD. However, eluates from set Fuji II were not cytotoxic. Eluates form set ZOE exhibited cytotoxicity with LD test. TNF-${\alpha}$ levels were high in eluates from freshly mixed Fuji II and Z100. Diluted eluates from freshly mixed Z100 and F2000 stimulated the production of TNF-${\alpha}$. However, there were no significant difference in TNF-${\alpha}$ levels compared to controls. These results indicate that some materials could possibly stimulate bone resorption in the periapical tissue by means of the production of bone resorptive cytokine.

A retrograde tracer, WGA-apo-HRP-gold, was injected into midline thalamic nuclei and subsequently orexin-A immunostaining was performed on the tuberal region of the hypothalamus in order to investigate orexinergic projections to the midline thalamus. Injection site was targeted within one specific region, i.e., paraventricular, centromedian, rhomboid, reuniens, or intermediodorsal nucleus, but it proved to be either one or a combination of these thalamic nuclei. The distribution of WG/orexin-double-labeled neurons exhibited a general pattern in that the majority of labeled cells were observed within the ventral portion of the lateral hypothalamus as well as the perifornical nucleus (PeF). A small number of double-labeled cells were also observed at the dorsomedial nucleus, the area dorsal to the PeF, dorsal portion of the lateral hypothalamus, and the posterior hypothalamus. These orexin-immunoreactive neurons might have wake-related influences over a variety of functions related with midline thalamic nuclei, which include autonomic control, associative cortical functions, and limbic regulation.

A 64-year-old man was admitted due to jaundice for 2 weeks. Radiologic findings revealed biliary stricture at the hepatic hilum with intrahepatic duct dilation suggesting Bismuth type IV Klatskin tumor. Jaundice improved spontaneously several days after hospitalization. Surgical treatment was considered but he only wanted to observe without specific treatment. Ten months later, he was re-admitted due to the recurrence of jaundice. Computed tomography (CT) showed no significant difference compared to previous results. Serum cancer antigen 19-9 and Immunoglobulin G4 were normal. Endoscopic forcep biopsy during endoscopic retrograde cholagiopancreatography (ERCP) revealed chronic inflammation. After steroid use under possible diagnosis of IgG4 related cholangiopathy, biliary stricture improved slightly. Four years later, he was hospitalized with the occurrence of acute cholangitis. Endoscopic retrograde biliary drainage was performed following endobiliary forcep biopsy. Pathology revealed well-differentiated adenocarcinoma at this time. Combined chemotherapy based on gemcitabine and cisplatin was performed. Six months later, CT revealed partial response.
