Detection, sequence analysis, and antibody prevalence of porcine deltacoronavirus in Taiwan.

Porcine deltacoronavirus (PDCoV) was initially documented in Hong Kong and later in the United States, South Korea, and Thailand. To investigate if PDCoV is also present in Taiwan, three swine coronaviruses-PDCoV, porcine epidemic diarrhea virus (PEDV), and transmissible gastroenteritis coronavirus (TGEV)-were tested using real-time reverse transcription polymerase chain reaction (rRT-PCR) in 172 rectal swab samples from piglets exhibiting diarrhea between January 2016 and May 2017 on 68 pig farms in Taiwan. The rRT-PCR results were positive for PDCoV (29/172, 16.

[Diurnal activity pattern and seasonal variations of captive Papio hamadryas.].

Activity rhythms and time budgets are two important components of ecological influences on animal individual behaviors. We collected data on activity pattern using instantaneous scan sampling on captive hamadryas baboons (Papio hamadryas) in Hangzhou Wild Animal Zoo in Zhejiang, China from November 2012 to October 2013. The results showed that: 1) In the activity time allocation, the main activities (frequency percentage was more than or equal to 5%) included resting (42.

Reduced tumorigenicity and drug resistance through the downregulation of octamer-binding protein 4 and Nanog transcriptional factor expression in human breast stem cells.

Breast cancer is the most common type of malignancy among females. Previous studies examining breast cancer tissue have demonstrated the presence of stem cells, and have detected octamer‑binding protein 4 (Oct4) and Nanog transcription factor expression. In the present study, breast cancer stem cells (CSCs) were isolated and enriched from MDA‑MB‑231 breast cancer cell lines, and were defined as MDA‑MB‑231 stem cells using flow cytometry.

[The clinical significance of preoperative enteral immune nutrition in patients with malignant gastrointestinal tumors].

Objective: To study the impact of preoperative enteral immune nutrition on patients with malignant gastrointestinal tumors.

Methods: 82 patients with malignant gastrointestinal tumors were divided equally into 2 groups:enteral nutrition group (EN) and normal diet group (Control). Enteral Nutritional Emulsion (TPF-T) served as nasogastically-fed liquid diet for the patients in EN group over a period of 7 days prior to surgery.
