The aim of this study was to clarify whether the apolipoprotein E gene (APOE) is related to ischemic stroke subtypes in Taiwan's Chinese population. Using the classification of Cerebrovascular Diseases III, 143 patients with lacunar infarction, 114 patients with atherothrombotic infarction, and 112 healthy controls were enrolled. APOE genotype was determined using polymerase chain reaction. Regarding the distribution of APOE genotypes, the frequency of ϵ3/ϵ4 genotypes in lacunar patients was significantly different from that in control subjects, by logistic regression, using ϵ3/ϵ3 as a referen

Background Postpancreatectomy diabetes can be caused by resection of functioning pancreatic tissue and is associated with postoperative pancreatic islet cell mass loss and subsequent endocrine dysfunction. Diabetes is a well‐known risk factor for ischemic heart disease. However, no previous studies have investigated ischemic heart disease in patients with postpancreatectomy diabetes and pancreatic cancer. Methods and Results Rates of patients with diabetes diagnosed with pancreatic cancer who underwent pancreatectomy between 2002 and 2019 in South Korea were obtained from the Korean National H

Abstract Immune cell infiltration has been implicated in neurotoxic chemotherapy for cancer treatment. However, our understanding of immune processes is still incomplete and current methods of observing immune cells are time consuming or invasive. Corneal dendritic cells are potent antigen-presenting cells and can be imaged with in-vivo corneal confocal microscopy. Corneal dendritic cell densities and nerve parameters in patients treated with neurotoxic chemotherapy were investigated. Patients treated for cancer with oxaliplatin (n = 39) or paclitaxel (n = 48), 3 to 24 months prior to assessme

Objectives: Bone tissue grinding is one of the common and basic applications in orthopedic surgery clinics. The grinding process is energy-intensive and generates a lot of grinding heat. The accumulation of this heat may cause thermal damage to biological tissues. This paper presents experimental research to investigate the bone-grinding heat and the cooling method. Methods: The combined influence of nozzle position and feed direction on the cooling effect of bone grinding under cryogenic spray cooling conditions is experimentally investigated.

The purpose of this study was to examine the effects of exercise in modulating biomarkers of sarcopenia in a treatment naïve transgenic adenocardinoma of the mouse prostate (TRAMP) model. Thirty TRAMP mice were randomized to either exercise (voluntary wheel running) or no-treatment control group for a period of 20 weeks. During necropsy, gastrocnemius muscles and prostate tumors were harvested and weighed. Gastrocnemius concentrations of myostatin, insulin-like growth factor (IGF)-1 and tumor necrosis factor (TNF)-α were quantified. Exercise mice had greater muscle mass than controls (p=0.04).

A cross-sectional microhardness (CSMH) test was carried out in human dental enamel exposed to a demineralizing solution in order to evaluate two different times of indentation in sound tissue and artificially induced caries. Twenty caries-free extracted human molars had one of their smooth surfaces sectioned and the enamel surface was isolated with nail polish except for an area of 6 mm2 . These specimens were submitted to artificially induced enamel caries on a lactate buffer containing 0.1 ppm fluoride (F) during 28 days.

Classroom-based language assessment (CBLA) in the Indonesian context has become more significant since the shift of the assessment model from summative based assessment (Ujian Nasional or the final exam) to formative-based assessment (Asesmen Kompetensi Minimum (AKM); therefore, teachers need to develop their classroom-based language assessment literacy (CBLAL). The model places a greater emphasis on students' learning outcomes in class rather than final test scores.
