Comparing Outcomes of Single-Incision Laparoscopic Herniorrhaphy in Newborns and Infants.

Background: As surgical techniques progress, laparoscopic herniorrhaphy is now performed more often in premature babies. The aim of this study was to analyze the outcomes of newborns and infants who underwent single-incision laparoscopic herniorrhaphy (SILH) at our center.

Methods: We retrospectively reviewed patients younger than 12 months old who received SILH at our department from 2016 to 2020.

Splenic Torsion in Heterotaxy Syndrome with Left Isomerism: A Case Report and Literature Review.

Splenic torsion is an unusual condition that results in congenital abnormality, especially in the visceral abnormal arrangement. We report the case of an 8.5-year-old boy with features in the right upper quadrant.

Effect of qigong training on fatigue in haemodialysis patients: A non-randomized controlled trial.

Background: Fatigue is a debilitating symptom in haemodialysis patients. Qigong presents a potentially safe modality of treatment for chronic fatigue patients but has not yet been evaluated in haemodialysis patients.

Objective: The aim of this study is to investigate whether qigong exercise affects fatigue in haemodialysis patients.

Inhibition of HSP90-dependent telomerase activity in amyloid β-induced apoptosis of cerebral endothelial cells.

Although apoptosis induced by amyloid β (Aβ) has been identified, the effect of Aβ on telomerase activity in relation to apoptosis induction remains unclear. In the present study, Aβ(1-40) and Aβ(25-35), but not Aβ(1-16) and Aβ(35-25), reduce the viability of primary cerebral endothelial cells (CECs) in accordance with apoptosis induction. Increases in caspase 3 and PARP protein cleavage with reductions of the Bcl-2/Bax protein ratio accompanied by a loss in the mitochondria membrane potential were identified in Aβ(1-40) and Aβ(25-35)-treated CECs.

Lung abscess predicts the surgical outcome in patients with pleural empyema.

Objectives: Most cases of pleural empyema are caused by pulmonary infections, which are usually combined with pneumonia or lung abscess. The mortality of patients with pleural empyema remains high (up to 20%). It also contributes to higher hospital costs and longer hospital stays.

Granular cell tumor of the lung.

A nodular lesion in the medial segment of right middle lobe was discovered on a chest radiograph for chronic cough in a 42-year-old Asian woman. A chest computed tomography (CT) scan subsequently showed a right middle lobe (RML) nodular lesion, which exhibited intense fluorodeoxyglucose uptake on positron emission tomography scan. A thoracoscopic RML lobectomy was then performed and immunohistochemical study and Ki-67 proliferative index on the pathology sample demonstrated a benign granular cell tumor.

Activation of telomerase and cyclooxygenase-2 in PDGF and FGF inhibition of C2-ceramide-induced apoptosis.

In the present study, the roles of telomerase and prostaglandin E(2) (PGE(2)) in platelet-derived growth factor (PDGF's) and fibroblast growth factor-2 (FGF-2's) effects against C(2)-ceramide-induced cell death were investigated. C(2)-ceramide reduced the viability of NIH3T3 cells in a condition without calf serum (CS) in accordance with decreasing telomerase activity according to the TRAP assay. The addition of CS significantly protected cells from C(2)-ceramide-induced apoptosis through increased telomerase activity, and the phosphorylations of PDGF and the FGF-2-like receptor in NIH3T3 cells were detected.

Plasma nuclear DNA and mitochondrial DNA as prognostic markers in corrosive injury patients.

Study Objectives: Ingestion of a corrosive substance produces an injury to the gastrointestinal tract and it is often difficult to evaluate the severity and prognosis of this injury. Increased concentrations of plasma nuclear DNA and mitochondrial DNA (mtDNA) have been found to be associated with the area of corrosion. This study examined the level of plasma DNA as it relates to the severity of corrosive injury.

Reactive oxygen species-dependent HSP90 protein cleavage participates in arsenical As(+3)- and MMA(+3)-induced apoptosis through inhibition of telomerase activity via JNK activation.

The effects of six arsenic compounds including As(+3), MMA(+3), DMA(+3), As(+5), MMA(+5), and DMA(+5) on the viability of NIH3T3 cells were examined. As(+3) and MMA(+3), but not the others, exhibited significant cytotoxic effects in NIH3T3 cells through apoptosis induction. The apoptotic events such as DNA fragmentation and chromosome condensation induced by As(+3) and MMA(+3) were prevented by the addition of NAC and CAT, and induction of HO-1 gene expression in accordance with cleavage of the HSP90 protein, and suppression of telomerase activity were observed in NIH3T3 cells under As(+3) and MMA(+3) treatments.

Differential apoptotic effect of wogonin and nor-wogonin via stimulation of ROS production in human leukemia cells.

We investigate the roles of methoxyl (OCH(3)) and hydroxyl (OH) substitutions at C8 of flavonoids on their apoptosis-inducing activities. Wogonin (Wog) and nor-wogonin (N-Wog) are structurally related flavonoids, and respectively contain an OH and OCH(3) at C8. In leukemia HL-60 cells, N-Wog exhibited more-potent cytotoxicity than Wog according to the MTT and LDH release assays, and the IC(50) values of Wog and N-Wog in HL-60 cells were 67.

12-o-Tetradecanoylphorbol 13-acetate prevents baicalein-induced apoptosis via activation of protein kinase C and JNKs in human leukemia cells.

In the present study, we found that baicalein (BE), but not its glycoside baicalin (BI), induced apoptosis in human leukemia HL-60 and Jurkat cells, but not in primary murine peritoneal macrophages (PMs) or human polymorphonuclear (PMN) cells, by the MTT assay, LDH release assay, and flow cytometric analysis. Activation of the caspase 3, but not caspase 1, enzyme via inducing protein processing was detected in BE-induced apoptosis. The ROS-scavenging activity of BE was identified by the anti-DPPH radical, DCHF-DA, and in vitro plasmid digestion assay, and none of chemical antioxidants including allpurinol (ALL), N-acetyl-cystein (NAC), and diphenylene iodonium (DPI) affected BE-induced apoptosis in HL-60 cells.

Baicalein inhibition of oxidative-stress-induced apoptosis via modulation of ERKs activation and induction of HO-1 gene expression in rat glioma cells C6.

In the present study, we examined the protective mechanism of baicalein (BE) and its glycoside, baicalin (BI), on hydrogen-peroxide (H(2)O(2))-induced cell death in rat glioma C6 cells. Results of the MTT assay, LDH release assay, and morphological observation showed that H(2)O(2) addition reduced the viability of C6 cells, and this was prevented by the addition of BE but not BI. Incubation of C6 cells with BE significantly decreased the intracellular peroxide level induced by H(2)O(2) according to flow cytometric analysis using DCHF-DA as a fluorescent substrate.

Quercetin inhibition of ROS-dependent and -independent apoptosis in rat glioma C6 cells.

In the present study, we investigated the protective mechanism of quercetin (QUE) and its glycosides, rutin (RUT) and quercitrin (QUI), on reactive oxygen species (ROS)-dependent (H(2)O(2)) and -independent (chemical anoxia) cell death in rat glioma C6 cells. Induction of HO-1 protein expression was detected in QUE- but not RUT- or QUI-treated C6 cells, and this was prevented by cycloheximide and actinomycin D. Incubation of C6 cells with QUE, but not RUT or QUI, protected C6 cells from H(2)O(2)- and chemical anoxia-induced cytotoxicity according to the MTT and LDH release assays.

Comparison between video-assisted thoracoscopic thymectomy and transternal thymectomy for myasthenia gravis (analysis of 82 cases).

Video-assisted thoracoscopic surgery (VATS) provides a new approach to thymectomy for myasthenia gravis (MG). We compared the results of video-assisted thoracoscopic thymectomy (VATT) and transternal thymectomy (TT) in Taiwanese people with MG. From January 1997 to August 2002, we enrolled a total of 82 patients with MG who underwent TT and anterior mediastinal adipose tissue removal in our study.
