Uṣṇīṣavijayā-dhāraṇī: The Complete Sanskrit Text Based on Nepalese Manuscripts
Gergely HIDAS 동국대학교 불교학술원 2020 International Journal of Buddhist Thought & Cultur Vol.30 No.2
While the Uṣṇīṣavijayā tradition received considerable scholarly attention regarding its Central and East Asian aspects, examinations of native South Asian evidence have been sparse. This paper offers now the first critical edition and translation of the Uṣṇīṣavijayā-dhāraṇī as it survives in Sanskrit manuscripts. Using ten Nepalese witnesses, the text with the nidāna, dhāraṇī and kalpa sections is presented, which throws light on key ritual practices involving caitya deposits of various materials to provide longevity.

Purpose: To compare percutaneous nephrolithotomy (PCNL) operations between patients with a preoperative nephrostomy tube and patients that the renal access was obtained at the time of the surgery. Materials and Methods: We retrospectively evaluated PCNL cases. Patients were divided into two groups. Group 1 – a non-nephrostomy tube (percutaneous nephrostomy, PCN) group and Group 2 – patients with a PCN placed before the procedure. All preoperatively placed PCN's were performed in emergency situations by interventional radiologists (IR). Complications were classified according to the Clavien-Dindo classification. We compared stone characteristics, operation time, complications, efficacy and PCN usability at surgery. Results: Five hundred twenty-seven patients who were submitted to PCNL for renal stones were included in the study. In 73 patients (13.9%) the PCNs were placed before the surgery. Patients and stone characteristics, mean operative time (p=0.830), complications (p=0.859) and stone-free rates (93.0%) were similar between the groups. There was a trend toward higher complication rates in Group 1, but the difference was not statistically significant. Only 21 (29.0%) of preoperatively placed PCNs were used during PCNL for establishing a tract. The reasons for not using PCN tract were: pelvic or infundibular insertion (30.0%) and suboptimal anatomic location (70.0%). Conclusions: Preoperative emergency inserted PCNs by IR usage rates were low during PCNL. Its placement neither affects the incidence of complications nor affects the operation time and outcomes. As such, when emergency renal drainage is indicated, the need for a future definitive PCNL should not influence the decision about the modality of renal drainage.
WHITE NOISE APPROACH TO FEYNMAN INTEGRALS
Hida, Takeyuki Korean Mathematical Society 2001 대한수학회지 Vol.38 No.2
The trajectory of a classical dynamics is determined by the least action principle. As soon as we come to quantum dynamics, we have to consider all possible trajectories which are proposed to be a sum of the classical trajectory and Brownian fluctuation. Thus, the action involves the square of the derivative B(t) (white noise) of a Brownian motion B(t). The square is a typical example of a generalized white noise functional. The Feynman propagator should therefore be an average of a certain generalized white noise functional. This idea can be applied to a large class of dynamics with various kinds of Lagrangians.
Pleiotrophin exhibits a trophic effect on survival of dopaminergic neurons in vitro

To understand what kind of trophic factors are up-regulated in dopamine(DA)-depleted striatum, we first analysed the up-regulation of mRNAs using a DNA microarray in DA-depleted striatum where DAergic inputs were denervated by 6-OHDA. We then investigated whether or not such trophic factors had an effect on cultured dopaminergic neurons. The microarray analysis revealed that pleiotrophin (PTN), glial-derived neurotopic factor(GDNF) and others were up-regulated in DA-depleted striatum. As PTN has been reported to have a wide range of trophic effects on neurons, we focused on the functional role of PTN in the present study. The increase in PTN mRNA was confirmed by Northern blotting at 1-3 weeks after the lesion, reaching a peak at 1 week. In embryonic day 15 mesencephalic neuron culture, PTN increased the number of tyrosine hydroxylase (TH)-positive neurons in a dose-dependent manner (125.2±2.0% of the control at 50ng/mL), while a family protein, midkine(10ng/mL) did not show any trophic effect (99.3±0.7%). In addition, the PTN effect on DAergic neurons was additive to the GDNF effect. As PTN did not increase the number of microtubule-associated protein-2(MAP 2)-positive neurons or promote the proliferation of dopaminergic progenitors in a bromodeoxyuridine(BrdU) labelling study, the effect appeared to enhance the specific survival of dopaminergic neurons. Expression of PTN receptors (syndecan-3, PTP-ζ) was detected on the cultured mesencephalic neurons, and also up-regulated in DA-depleted striatum. The data indicate that PTN is up-regulated in DA-depleted striatum and exhibits a trophic effect specifically on the survival of cultured dopaminergic neurons.
