On the Ultrastructure and Function of Rhogocytes from the Pond Snail Lymnaea stagnalis

2015

Rhogocytes, also termed “pore cells”, occur as solitary or clustered cells in the connective tissue of gastropod molluscs. Rhogocytes possess an enveloping lamina of extracellular matrix and enigmatic extracellular lacunae bridged by cytoplasmic bars that form 20 nm diaphragmatic slits likely to act as a molecular sieve. Recent papers highlight the embryogenesis and ultrastructure of these cells, and their role in heavy metal detoxification. Rhogocytes are the site of hemocyanin or hemoglobin biosynthesis in gastropods. Based on electron microscopy, we recently proposed a possible pathway of hemoglobin exocytosis through the slit apparatus, and provided molecular evidence of a common phylog…

"Kouzlo dálky" i "mechanismus kaváren a vináren" - uwagi o (nie)pamięci w korespondencji Jana Zahradníčka z Františkiem Halasem

2021

The article analyses letters exchanged in the years 1930 to 1949 between two outstanding Czech poets - Jan Zahradníček and František Halas. Despite their contrary views (Zahradníček was perceived as an ardent Catholic, while Hałas – as holding rather left-wing worldviews), their written communication is a testimony of their friendship which lasted for two decades. However, in the letters there are also expressed, especially in the final stage of their correspondence, numerous radical judgments of the thickening atmosphere (years of the war and Soviet domination) surrounding both artists as well as mutual assessments of their social and ethical attitudes. Their correspondence can be also vie…

The assessment of skeletal status in young patients with Turner syndrome by 2 densitometric techniques: Phalangeal quantitative ultrasound and dual e…

2018

Background. Studies using dual energy X-ray absorptiometry (DXA) demonstrate a reduction in bone mineral density (BMD) in children and adolescents with Turner syndrome (TS). However, these studies do not take into account changes in bone size, which influence BMD in the case of short-statured patients. Phalangeal quantitative ultrasound (phQUS) measurements have shown an ability to reveal changes due to skeletal growth, aging, and bone and mineral disorders. There is limited data on bone mineral status in girls with TS assessed by 2 different techniques, i.e., DXA and phQUS. Objectives. The aim of this study was to investigate the potential negative impact of TS on bone status and to assess…

Patterns of trunk spine growth in two congeneric species of acanthocephalan: investment in attachment may differ between sexes and species.

2012

SUMMARYAcanthocephalans have evolved a hooked proboscis and some taxa have trunk spines to attach to their definitive hosts. These structures are generated before being used, thus a key question is how investment in attachment could optimally be allocated through the ontogeny. The number and arrangement of hooks and spines are never modified in the definitive host, but it is unclear whether these structures grow during adult development. A comparison of the size of trunk spines between cystacanths and adults of Corynosoma cetaceum and C. australe indicated that spines grow in both species, but only in females, which also had significantly larger spines than males. This sexual dimorphism did…

Day and Night Control of COPD and Role of Pharmacotherapy: A Review

2020

Abstract The topic of 24-hour management of COPD is related to day-to-night symptoms management, specific follow-up and patients’ adherence to therapy. COPD symptoms strongly vary during day and night, being worse in the night and early morning. This variability is not always adequately considered in the trials. Night-time symptoms are predictive of higher mortality and more frequent exacerbations; therefore, they should be a target of therapy. During night-time, in COPD patients the supine position is responsible for a different thoracic physiology; moreover, during some sleep phases the vagal stimulation determines increased bronchial secretions, increased blood flow in the bronchial circ…

Pourquoi j'ai encore faim ?

2019

Comment les sensations de faim et de satiété sont produites par notre cerveau ? Quelle zone de notre cerveau va s’activer aux horaires des repas et sur la base de quelles stimulations ? À travers quelques exemples, Alexandre Benani illustrera l’importance du dialogue entre nos organes et notre cerveau dans l’élaboration de ces sensations.
