Bioplastic fishing nets as a sustainable alternative against ghost fishing: Results from the year-long testing among artisanal fishermen for operational effectiveness and social acceptance.

This study investigated the operational effectiveness and social acceptance of bioplastic gillnets made from a biobased polyester blend used to develop a monofilament 0.33 mm in diameter, with linear density of 108 tex, tenacity of 24.4 cN/tex and breaking force of 3.

Post-exercise ankle blood pressure and ankle to brachial index after heavy load bicycle exercise.

The American Heart Association (AHA) recommendations for diagnosing peripheral artery disease (PAD) after exercise are a decrease >20% of ankle brachial index (ABI) or >30 mm Hg of ankle systolic blood pressure (ASBP) from resting values. We evaluated ABI and ASBP values during incremental maximal exercise in physically active and asymptomatic patients. Patients (n = 726) underwent incremental bicycle tests with pre- and post-exercise recording of all four limbs arterial pressures simultaneously.

Can the scoring of the walking estimated limitation calculated by history (WELCH) questionnaire be simultaneously simplified and improved?

Background: The WELCH questionnaire includes 4 items (A, B, C and D) and estimates the maximal walking time (MWT) on treadmill in patients with claudication. Its scoring was empirically defined. We aimed to test various methods for scoring to estimate whether the scoring of the WELCH could be improved or simplified.

External validation of the "walking estimated limitation calculated by history" (WELCH) questionnaire in patients with claudication.

Objective: To externally validate the recently proposed "Walking Estimated Limitation Calculated by History" (WELCH) questionnaire.

Methods: A prospective study was performed on 450 new patients referred to our laboratory for treadmill testing (constant load 3.2 km/h and 10% slope for 15 minutes and then incremental increases).

[Giant mitochondria in the A cells of the pancreas of a lizard: Varanus niloticus].

Pancreatic A cells of the lizard Varanus niloticus are characterized by the presence of two types of mitochondria: (a) normal, small mitochondria (about 0.4 X 1 micron), and (b) giant mitochondria, measuring up to 9 micron in length and 1 micron in diameter. Giant mitochondria show various shapes.

Alterations of endocrine pancreas B cells in a sahelian reptile (Varanus exanthematicus) during starvation.

During the long starvation period (November to June) of the lizard (Varanus exanthematicus), pancreatic B cells undergo profound modification. The degeneration of beta granules observed in electron microscopy appears correlated with the diminution of the immunoreactive insulin-like content of the pancreas. The analogy between the phenomena observed here and those reported in animals treated with alloxan is discussed.

Ultrastructure of the exocrine pancreas in a sahelian reptile (Varanus exanthematicus) during starvation.

During the sahelian dry season (November to June) the lizard Varanus exanthematicus fasts, and during these 8 months its pancreatic acinar cells lack zymogen granules and show an inactive Golgi body and damaged mitochondria. The main peculiarity can be observed in the granular endoplasmic reticulum (GER): Each acinar cell posesses a great number of GER vesicles (mean diameter 0.15 μm) and a large spheroid GER resulting from either the nesting of some cisternae or the rolling up of a single cisternae on itself.
