The medicine development and upwardly raised standard of living brings out the increased dental needs at dental hospital OPD. The dental college hospital, follows up the raised dental needs, was subdivided by specialized dental office. And now a specialized dental office needs co-work with the other specialized dental office for special dental illness and treatment. The purpose of this study is to provide a proper area distribution and location of each specialized dental office and relationship between dental office, clinic and other department by analyzing the space, area and characteristics of dental hospital OPD. The results could be used for helping its users, of patients and dentists.

This review article described the electrochemical Frumkin, Langmuir, and Temkin adsorption isotherms of over-potentially deposited hydrogen (OPD H) and deuterium (OPD D) for the cathodic $H_2$ and $D_2$ evolution reactions (HER, DER) at Pt, Ir, Pt-Ir alloy, Pd, Au, and Re/normal ($H_2O$) and heavy water ($D_2O$) solution interfaces. The Frumkin, Langmuir, and Temkin adsorption isotherms of intermediates (OPD H, OPD D, etc.) for sequential reactions (HER, DER, etc.) at electrode/solution interfaces are determined using the phase-shift method and correlation constants, which have been suggested and developed by Chun et al. The basic procedure of the phase-shift method, the Frumkin, Langmuir, and Temkin adsorption isotherms of OPD H and OPD D and related electrode kinetic and thermodynamic parameters, i.e., the fractional surface coverage ($0{\leq}{\theta}{\leq}1$) vs. potential (E) behavior (${\theta}$ vs. E), equilibrium constant (K), interaction parameter (g), standard Gibbs energy (${\Delta}G_{\theta}{^{\circ}}$) of adsorption, and rate (r) of change of ${\Delta}G_{\theta}{^{\circ}}$ with ${\theta}$ ($0{\leq}{\theta}{\leq}1$), at the interfaces are briefly interpreted and summarized. The phase-shift method and correlation constants are useful and effective techniques to determine the Frumkin, Langmuir, and Temkin adsorption isotherms and related electrode kinetic and thermodynamic parameters (${\theta}$ vs. E, K, g, ${\Delta}G_{\theta}{^{\circ}}$, r) at electrode/solution interfaces.

한국 내 물쇠뜨기 여섯 개 자연 집단의 표현형적 유연 관계를 RAPD 마커에 근거하여 집단수준에서 조사하였다. 또한 RAPD로 물쇠뜨기 집단의 유전적 다양성과 집단구조를 분석하였다. 물쇠뜨기는 평균 26.7%의 유전적 다형성을 나타내었다. 물쇠뜨기는 대립유전자좌위당 적은 수의 좌위(1.267)와 유효한 유전자좌위(1.176)를 나타내었다. 물쇠뜨기의 유전적 다양도(H)는 0.102로 유사한 생활사를 가진 다른 종에 비해 낮았다. 전체 유전적 다양도($H_T$)는 0.112(OPD-07)에서 0.445(OPD-16)까지였으며 평균은 0.141이었다. 전체 유전적 다양도에서 집단 내 다양도($H_S$)는 0.102로 낮았다. 이런 낮은 물쇠뜨기의 다양도는 무성적 생식, 작은 집단 크기, 집단화 과정 등으로 설명될 수 있었다. 유전자좌위에 근거한 집단간 분화를 나타내는 다양도는 비율은 OPD-07의 0.129에서 OPD-09에 0.455로 평균은 0.277이었다. 전체 유전적 변이에서 집단간 변이는 27.7%였으며 나머지 변이의 72.3%는 집단 내에 있었다. 본 결과는 물쇠뜨기의 분류학적 연구 및 집단유전학에 기여할 수 있을 것이다.

The seven selected primers OPA-02, OPA-04, OPA-18, OPD-07, OPD-08, OPD-15 and OPD-16 were used to generate unique shared loci to each species and shared loci by the two species. The hierarchical dendrogram indicates three main branches: cluster 1 (RORETZI 01~RORETZI 11) and cluster 2 (HILGENDORF 12~HILGENDORF 22) from two geographic populations of ascidians, Halocynthia roretzi and H. hilgendorfi. The shortest genetic distance displaying significant molecular difference was between individuals' HILGENDORF no. 14~HILGENDORF no. 19 (genetic distance =0.008). Ultimately, individual no. 02 of the RORETZI ascidian was most distantly related to HILGENDORF no. 21 (genetic distance=0.781). These results demonstrate that the H. roretzi population is genetically different from the H. hilgendorfi population. From what has been said above, the potential of PCR analysis to identify diagnostic markers for the identification of two ascidian populations has been demonstrated. Generally speaking, using a variety of decamer primers, this PCR method has been applied to identify specific markers particular to line, species and geographical population, as well as genetic diversity/polymorphism in diverse species of organisms.

Backgrounds/Aims: Postoperative pancreatic fistula is the key worry in the ongoing debate about the safety and effectiveness of total laparoscopic pancreaticoduodenectomy (TLPD). Laparoscopic-assisted pancreaticoduodenectomy (LAPD), a hybrid approach combining laparoscopic resection and anastomosis with a small incision, is an alternative to TLPD. This study compares the short-term outcomes and oncological efficacy of LAPD vs. open pancreaticoduodenectomy (OPD). Methods: A retrospective analysis of data of all patients who underwent LAPD or OPD for periampullary carcinoma at a tertiary care center in Northeast India from July 2019 to August 2023 was done. A total of 30 LAPDs and 30 OPDs were compared after 1:1 propensity score matching. Demographic data, intraoperative and postoperative data (30 days), and pathological data were compared. Results: The study included a total of 93 patients, 30 underwent LAPD and 62 underwent OPD. After propensity score matching, the matched cohort included 30 patients in both groups. The LAPD presented several advantages over the OPD group, including a shorter incision length, reduced postoperative pain, earlier initiation of oral feeding, and shorter hospital stays. LAPD was not found to be inferior to OPD in terms of pancreatic fistula incidence (Grade B, 30.0% vs. 33.3%), achieving R0 resection (100% vs. 93.3%), and the number of lymph nodes harvested (12 vs. 14, p = 0.620). No significant differences in blood loss, short-term complications, pathological outcomes, readmissions, and early (30-day) mortality were observed between the two groups. Conclusions: LAPD has comparable safety, technical feasibility, and short-term oncological efficacy.

In order to improve their hospital services in unlimited competitive situations, the general hospitals, particularly, have since the 1990s been concentrating more on hospital information processing systems and the automation of the patients' convenience. They also give priority to the advance of integrated hospital information systems centred around the patients. Introducing more progressive information technology to already established hospitals, the OPD has been most affected by HIS because there are a lot of patients and doctors. On this background, this study analyse the change of OPD and some related departments around the 1990s with the general hospitals as it's object. It investigates the way of building hospitals and presents some information about the planning of building hospitals.

Oligopeptidase B (OpdB) is a serine peptidase widespread among bacteria and protozoa that has emerged as a virulence factor despite its function has not yet been precisely established. By using an OpdB-overexpressing Escherichia coli strain, we found that the overexpressed peptidase makes the bacterial cells specifically less susceptible to several proline-rich antimicrobial peptides known to penetrate into the bacterial cytosol, and that its level of activity directly correlates with the degree of resistance. We established that E. coli OpdB can efficiently hydrolyze in vitro cationic antimicrobial peptides up to 30 residues in length, even though they contained several prolines, shortening them to inactive fragments. Two consecutive basic residues are a preferred cleavage site for the peptidase. In the case of a single basic residue, there is no cleavage if proline residues are present in the $P_1$ and $P_2$ positions. These results also indicate that cytosolic peptidases may cause resistance to antimicrobial peptides that have an intracellular mechanism of action, such as the proline-rich peptides, and may contribute to define the substrate specificity of the E. coli OpdB.

Background: The purpose of this study was to examine the extent and evaluation of pain after total abdominal hysterectomy (TAH) and to establish correlation between three types of pain; pain at rest, pain with movement and pain with coughing (maximum pain). Methods: The present study compared quality of pain during pain management in 48 patients undergoing TAH. Patients received i.v. meperidine as loading dose in the recovery room and PCA with nalbuphine 90 mg, ketorolac 180 mg, buprenorphine 0.9 mg, droperidol 5 mg, plasma solution A 28 ml for 3 days. The PCA device used was the Baxter infusor$^{(R)}$ (PCA module PC-19-55, 0.5 ml/hr basal rate, 15 minute lockout interval). Patients were then interviewed on Operative Day (OPD), Postoperative Day 1, 2, and 3 (POD 1, 2 and 3) to assess their pain on a visual analogue scale (VAS) of 0 (none) to 10 (worst imaginable). Results: The mean pain score at rest was 2.0 on OPD and decreased to 0.7 on POD 3. The mean pain score with movement was 3.2 on OPD and decreased to 1.6 on POD 3. The mean pain score with coughing was 4.2 on OPD and decreased to 2.2 on POD 3. Conclusions: Patients' experience of three types of postoperative pain emphasizes the need for more effective pain management.
