Pepsin is common digestive enzyme used for fish digestion in the laboratory to collect trematode metacercariae. In a field study, to survey the infected fish is needed a huge yield of pepsin and it is very expensive. Therefore, our purpose of this study was to investigate the candidate enzyme from pineapple juice which has a digestive enzyme called bromelain, a mixture of proteolytic enzymes, to digest fish in order to harvest metacercariae. Fish were divided into 2 groups: one group in which metacercariae were harvested using acid pepsin as a control and other groups in which the fish was digested using fresh pineapple juices...

BACKGROUND: The timed-up-and-go test (TUG) is one of the most commonly used tests of physical function in clinical practice and for research outcomes. Inertial sensors have been used to parse the TUG test into its composite phases (rising, walking, turning, etc.), but have not validated this approach against an optoelectronic gold-standard, and to our knowledge no studies have published the minimal detectable change of these measurements. METHODS: Eleven adults performed the TUG three times each under normal and slow walking conditions, and 3 m and 5 m walking distances, in a 12-camera motion analysis laboratory...

Activity recognition through smartphones has been proposed for a variety of applications. The orientation of the smartphone has a significant effect on the recognition accuracy; thus, researchers generally propose using features invariant to orientation or displacement to achieve this goal. However, those features reduce the capability of the recognition system to differentiate among some specific commuting activities (e.g., bus and subway) that normally involve similar postures. In this work, we recognize those activities by analyzing the vibrations of the vehicle in which the user is traveling...

Yongchuan Tang, Deyun Zhou, Shuai Xu, Zichang He
In real applications, how to measure the uncertain degree of sensor reports before applying sensor data fusion is a big challenge. In this paper, in the frame of Dempster-Shafer evidence theory, a weighted belief entropy based on Deng entropy is proposed to quantify the uncertainty of uncertain information. The weight of the proposed belief entropy is based on the relative scale of a proposition with regard to the frame of discernment (FOD). Compared with some other uncertainty measures in Dempster-Shafer framework, the new measure focuses on the uncertain information represented by not only the mass function, but also the scale of the FOD, which means less information loss in information processing...

Background: Gallbladder stone (GBS) is a common gastrointestinal disease that can progress to severe cholecystitis and is a strong risk factor for gallbladder cancer (GBC). The present study was conducted to evaluate region-specific causes of GBS which was proved as major risk factor for GBC in Jeju Island, Korea. Methods: Age and sex match case-control study was performed among 171 pairs of case and controls. The cases were patients who were diagnosed with GBS, had definite clinical symptoms, and underwent a cholecystectomy in Cheju Halla General Hospital, Jeju, Korea during 2010-2014...

OBJECTIVES: The purpose of this study was to assess the relationship between nonalcoholic fatty liver disease (NAFLD) and arterial stiffness in nondiabetic, nonhypertensive postmenopausal women with and without metabolic syndrome. METHODS: We divided 1007 postmenopausal women into two groups (NAFLD and controls) and then three groups (NAFLD with metabolic syndrome, NAFLD without metabolic syndrome, and controls), respectively. To exclude the influence of confounding factors, we studied a specifically selected group with no additional cardiovascular risk...

STUDY DESIGN: Prospective chart review. OBJECTIVE: It is well-known that radiation exposure during minimally invasive spine procedures can be substantial. Less interest has focused on setup radiation exposure before incision, including preoperative images used for surgical approach. The present study seeks to better quantify the significance of setup radiation in the total radiation exposure of minimally invasive spine surgery. SUMMARY OF BACKGROUND DATA: Radiographic localization is necessary in minimally invasive spine procedures to visualize anatomy, but increased radiation exposure is associated with health risks...

Adipose tissue is a complex and multi-faceted organ. It responds dynamically to internal and external stimuli, depending on the developmental stage and activity of the organism. The most common functional subunits of adipose tissue, white and brown adipocytes, regulate and respond to endocrine processes, which then determine metabolic rate as well as adipose tissue functions. While the molecular aspects of white and brown adipose biology have become clearer in the recent past, much less is known about sex-specific differences in regulation and deposition of adipose tissue, and the specific role of the so-called pink adipocytes during lactation in females...

Potassium (K) plays important roles in the metabolism of carbon (C) and nitrogen (N), but studies of K deficiency affecting C-N balance are lacking. This study explored the influence of K deficiency on C-N interaction in cotton leaves by conducting a field experiment with cotton cultivar DP0912 under two K rates (K0: 0 kg K2O ha(-1) and K67: 67 kg K2O ha(-1)) and a controlled environment experiment with K-deficient solution (K1: 0 mM K(+)) and K-sufficient solution (K2: 6 mM K(+)). The results showed that leaf K content, leaf number, leaf area, boll number, reproductive dry weight and total dry weight were significant lower under K deficiency (K0 or K1)...

This work evaluated the effect of in vitro drought stress on morphological characteristics, phenolic compounds, flavonols, saponin content, and antioxidant activity in plantlets of Agave salmiana. Drought stress was induced with polyethylene glycol (PEG) at 0, 10, 20 and 30% w/v in Murashige and Skoog solid medium. The determination of specific flavonols and saponins was achieved via HPLC-DAD and HPLC-ELSD, respectively. Compared with the control, plants grown in 30% PEG showed a change in the width of the leaves and a different color, showing less clarity and more darkening (L = 21...

Intracellular metabolism in skeletal muscle has been studied for more than a century and is the stuff of textbooks. In contrast, the extracellular secretion of metabolites by muscle cells, and their effects on non-muscle cells near or far, has been investigated much less extensively. Here, we describe a number of cases in which striated muscle secretes a metabolite that elicits complex responses in other cells or tissues, with involvements in normal physiology as well as obesity, type II diabetes, and cardiac remodeling...

Unsaturated ethers are oxygenated volatile organic compounds (OVOCs) emitted by anthropogenic sources. Potential removal processes in the troposphere are initiated by hydroxyl (OH) radicals and photochemistry. In this work, we report for the first time the rate coefficients of the gas-phase reaction with OH radicals (kOH) of 2-chloroethyl vinyl ether (2ClEVE), allyl ether (AE), and allyl ethyl ether (AEE) as a function of temperature in the 263-358 K range, measured by the pulsed laser photolysis-laser induced fluorescence technique...

After ultrasonic-assisted extraction, four lycoris radiata alkaloids: galanthamine, homolycorine, lycorenine, and tazettine were determined by capillary electrophoresis electrochemiluminescence. Polyvinylpyrrolidone was added to the running buffer (RB) to obtain better resolution. Experimental conditions influencing the determination were examined, including the additives, detection potential, separation voltage, injection voltage and time, and RB pH and concentration. Under optimal experimental conditions, the baseline separation of the four alkaloids occurred within 16min...
