The mechanisms thought to be responsible for these changes are increased energy expenditure resulting from increased basal metabolic rate and/or high levels of physical activity, inadequate energy intake, fluid loss as well as gastrointestinal malabsorption. The severity of hypoxia, the duration of exposure as well as the level of physical activity also seem to play crucial roles in the final outcome. On one hand, excessive weight loss in mountaineers exercising at high altitudes may affect performance and climbi...

This study aimed to determine the effect of the consumption of peel flour or pulp flour from two varieties of Solanum tuberosum (Yungay potato and Canchán potato) on the accumulation of adipose tissue, organ weight, and oxidative stress in the liver of rats. We carried out an experimental study in 24 obese Holtzman rats, divided into four groups and subjected to diets containing 10% flour from both varieties of potato. The groups were T1: Yungay peel; T2: Yungay pulp; T3: Canchán peel; and T4: Canchán pulp. When the study was completed, all the animals were slaughtered to record the weights of organs a...

Authors: Lancellotti P, De Pauw M, Claeys M Abstract Cardiovascular disease (CVD) and cancer represent the two main causes of death in industrialised countries. Both share common risk factors (diabetes, obesity, hypertension, diet, smoking, etc.). The associated timing of CVD and cancer onset is thus largely influenced by modifiable risk factors. Advances in cancer treatment have extended the lives of patients with cancer, but for some at the cost of adverse cardiovascular events. The rapidly growing number of patients surviving cancer, often in the setting of advanced age, new or pre-existing CV disease and risk f...

AbstractTo investigate the prevalence of different patterns of cemento-enamel junction (CEJ) morphology under swept-source optical coherence tomography (SS-OCT). One hundred extracted human teeth were used consisting of incisors, premolars, and molars. Each sample was observed for every 500  μm circumferentially along CEJ and OCT images of the pattern were noted. Microscopic observations were done for the representative sample using confocal laser scanning microscope (CLSM) and transmission electron microscope (TEM). The OCT images exhibited four CEJ patterns: edge-to-edge (type I), exposed dentin (type II), cement...

Authors: Lai G, Guo N, Jiang Y, Lai J, Li Y, Lai R Abstract OBJECTIVE: To assess whether the duration of one-lung ventilation (OLV) affects postoperative pulmonary complications after McKeown esophagectomy for esophageal cancer. METHODS: A retrospective analysis of data stored in a database for esophageal cancer was carried out to identify predictors of postoperative pulmonary complications in patients undergoing McKeown esophagectomy at Sun Yat-sen University Cancer Center between 2010 and 2012. RESULTS: Patients in the OLV ⩾150 minutes group had a higher incidence of postoperative pulmonary complication...

Although the use of Nivolumab prolongs survival in a number of patients, this treatment is hampered b...

In conclusion, cfDNA and cftDNA exhibit the potential to become novel biomarkers for the response assessment following cancer treatment, and may serve as a tool for the estimation of tumor volume. The current study further supports the increasingly important role of cfDNA and cftDNA as new monitoring tools for use during cancer therapy. PMID: 31966080 [PubMed]

Authors: Liu J, Yang L Abstract Effects of propofol and sevoflurane on blood glucose, hemodynamics, and inflammatory factors of patients with type 2 diabetes mellitus (T2DM) and gastric cancer (GC) were investigated. One hundred and ten patients with T2DM and GC, treated in The First Affiliated Hospital of Baotou Medical College (Baotou, China) from January 2017 to December 2018, were selected. Sixty patients anesthetized by propofol were included in the propofol group, whereas 50 patients anesthetized by sevoflurane were included in the sevoflurane group. The level of blood glucose, hemodynamic indicators, and inf...
