Jaihwan Kim
Endoscopic retrograde cholangiopancreatography (ERCP) is a key endoscopy skill used to diagnose and treat pancreatobiliary diseases. However, its diagnostic use is decreasing in favor of other less invasive methods such as magnetic resonance cholangiopancreatography and endoscopic ultrasound. Alternatively, its use has become more important in the therapeutic area. ERCP trainees must know the anatomy and physiology of the pancreatobiliary system, several key basic skills, and complications of a successful procedure...

JUSTIFICATION AND OBJECTIVES: Patients affected by gynecological or gastrointestinal tract neoplasms that evolve to peritoneal carcinomatosis experience a significant drop in their quality of life, high morbidity and short survival times with currently available chemotherapeutic schemes. The surgical treatment based on cytoreduction and the employment of hyperthermic intraperitoneal chemotherapy in the intra-operative period is a true challenge to anesthesiologist. CASE REPORT: A 67 years old patient diagnosed with mucinous adenocarcinoma of the Appendix associated with mucinous carcinomatosis, was submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), under general anesthesia and epidural block...

The present study investigated the reactivity and oxidation mechanisms of salbutamol (SAL) and terbutaline (TBL), two typical β2-adrenoceptor agonists, towards sulfate radical (SO4(-)) by using photo-activated persulfate (PS). The reaction pathways and mechanisms were proposed based on products identification using high resolution HPLC-ESI-MS, laser flash photolysis (LFP) and molecular orbital calculations. The results indicated that SO4(-) was the dominant reactive species in the UV/PS process. The second-order rate constants of sulfate radical reaction with SAL and TBL were measured as (3...

By performing an in-depth analysis of one high profile example, this article aims to help breastfeeding support professionals understand the methodological flaws that characterize recent studies claiming to show the efficacy of frenotomy for the diagnoses of posterior tongue-tie and upper lip-tie. The example study does not address definitional confusion or control for the effects of the passage of time. It does not consider the effects of caring attention, validation, and lactation consultant support. It also does not consider the extensive research over the past three decades that has established that reflux in the first 6 months of life is benign, even though increased reflux frequency may correlate with unsettled infant behavior...

Toxoplasma gondii primary infection in pregnancy is associated with poor obstetric outcomes. This study aimed to determine the seroprevalence of Toxoplasma infection in pregnant migrant and refugee women from Myanmar attending antenatal care in Thailand. A random selection of 199 residual blood samples from first antenatal screen in 2014-2015 was tested for Toxoplasma IgG and IgM antibodies. Seroprevalence of Toxoplasma infection was 31.7% (95% confidence interval = 25.6-38.4). Avidity testing in the three positive IgM cases indicated all were past infections...

Aqueous-phase oxidation of cis-pinonic acid (CPA) by hydroxyl radicals (OH) was studied using a relative rate technique under acidic and basic conditions. Liquid chromatography (LC) coupled to the negative electrospray ionization (ESI) quadrupole tandem mass spectrometry (MS/MS) was used to monitor a disappearance of CPA and reference compounds. The measured second order reaction rate coefficients of CPA with OH were: 3.6 ± 0.3 × 10(9) M(-1)s(-1) (pH=2) and 3.0 ± 0.3 × 10(9) M(-1)s(-1) (pH = 10) - combined uncertainties are 2σ...

Clinicians have long been aware of the danger of overreliance on opioids to manage acute pain, such as the pain accompanying surgery. The risk of adverse drug events is higher with opioids than with any other common class of drugs. Overreliance on opioids increases length of stay and hospital costs, while decreasing patient satisfaction. Opioids can lead to problems that continue well after discharge, including chronic pain, abuse and addiction, and even death. Increasingly, prescribed opioids have proved to lead to heroin addiction...

During evolution, the cell as a fine-tuned machine had to undergo permanent adjustments to match changes in its environment, while "closed for repair work" was not possible. Evolution from protists (protozoa and unicellular algae) to multicellular organisms may have occurred in basically two lineages, Unikonta and Bikonta, culminating in mammals and angiosperms (flowering plants), respectively. Unicellular models for unikont evolution are myxamoebae (Dictyostelium) and increasingly also choanoflagellates, whereas, for bikonts, ciliates are preferred models...

The emerging, next generation of people engaged as managers in agriculture differs from the "baby boomer" farm generation that relishes certain traditions and an agrarian lifestyle. These futuristic producers and managers have been raised in a society that promulgates safety environment rules. They have witnessed lives saved by automobile seatbelts and lives improved from clean air and water. They know the basic cost of effective safety compliance is relatively fixed, regardless of the number of employees, and they are willing to invest resources that ensure a culture of safety, because it is economically beneficial, socially responsible, and probably required by the companies to whom they need to market their products...

A systematic study of the N-substitution reactions of 3-substituted pyrazoles under basic conditions has been undertaken. Regioselective N1-alkylation, -arylation, and -heteroarylation of 3-substituted pyrazoles have been achieved using K2CO3-DMSO. The regioseletivity is justified by the DFT calculations at the B3LYP/6-31G**(d) level. A consistent steric effect on chemical shift has been observed for N-alkyl pyrazole analogs. 25 X-ray crystallographic structures have been obtained to confirm the regiochemistry of the major products...

The development of cathode-active material of Li battery is important for the current emerging energy transferring and saving problems. A stable crystalline microporous complex metal oxide based on Mo, V, and Bi is an active and suitable material for Li battery. High capacity (380 Ah/kg) and stable cycle performance are achieved. X-ray absorption near-edge structure analyses demonstrate that the original Mo(6+) and V(4+) ions are reduced to Mo(4+) and V(3+) in the dis-charging process, respectively, which results in a 70-electron reduction per formula...

Nearly 38% of unplanned pregnancies occur because of unmet contraceptive needs. In HIV-positive women, these figures triple, a phenomenon explained by social determinants such as poverty, access to health services, violence, and forced displacement, all of which are frequent elements in the lives of these women. Unplanned pregnancies represent a psychological burden related to women's fear of transmitting the infection to their children, orphanhood, and assuming risks during pregnancy, in addition to family and social consequences that are expressed in lack of prenatal care, neglect of their health, and an increased likelihood of vertical transmission...

In recent years, it has been demonstrated that malignancy arises and advances through the molecular interplay between tumor cells and non-malignant elements of the tumor stroma, that is, fibroblasts and extracellular matrix. However, in contrast to the mounting evidence about the role of tumor stroma in the genesis and progression of the malignant disease, there are very few data regarding the uninvolved stromal tissue in the remote surrounding of the tumor. Using the objective morphometric approach in patients with adenocarcinoma, we demonstrate the remodeling of extracellular matrix of the lamina propria in the uninvolved rectal mucosa 10 and 20 cm away from the neoplasm...

BACKGROUND: Body Mass Index (BMI) is considered as a major determinant of health. The objective of study was to find out differences between dietary practices, as well as BMI in educated housewives and working woman. It is supposed that both study groups may have difference in work pressures with resultant diverse preferences for food. This can affect health status particularly in relation to obesity in women. Furthermore, we selected participants with 14 years' education expecting basic awareness of healthful diet...
