[Anatomical landmarks for peripheral neural blocks of the forearm and the wrist: A cadaveric study].

Background: There are no data ensuring a standardized landmark-based-technique for blocking sensitive nerves of the forearm.

Purpose: To identify locations were with use of good palpable bony landmarks and lines between them sensitive nerve blocks on the forearm can be done with great success.

Material And Methods: Dissection of the superficial branch of the radial nerve (SBRN), the dorsal branch of the ulnar nerve (DBUN), the lateral, medial and dorsal antebrachial cutaneous nerve (LACN, MACN, and DACN) as well as the palmar branch of the median nerve (PBMN) was performed on five upper limbs of five different Caucasian cadavers.

Cyanobacterial Toxic and Bioactive Peptides in Freshwater Bodies of Greece: Concentrations, Occurrence Patterns, and Implications for Human Health.

Cyanobacterial harmful algal blooms represent one of the most conspicuous waterborne microbial hazards in aquatic environments mostly due to the production of toxic secondary metabolites, mainly microcystins (MCs). Other bioactive peptides are frequently found in cyanobacterial blooms, yet their concentration and ecological relevance is still unknown. In this paper we studied the presence and concentration of cyanobacterial peptides (microcystins, anabaenopeptins, anabaenopeptilides) in 36 Greek freshwater bodies, using HPLC-DAD, ELISA, and PP1IA.

Altered cortical activation from the hand after facial botulinum toxin treatment.

Plastic interactions between face and hand cortical tactile circuits occur after severe injuries that affect the hand such as in amputation or spinal cord injury. However, whether loss of facial movements alters the cortical circuits involved in processing tactile inputs from the hand remains unknown. In this prospective observational study we used electroencephalography (EEG) to measure cortical activity evoked by tactile stimulation of the hands before and after botulinum toxin-A-induced facial paralysis.

The essential oils of the Greek endemic Satureja horvatii ssp. macrophylla in relation to bioclimate.

The essential oils of the Greek endemic Satureja horvatii subsp. macrophylla collected from 36 areas (among them, 23 are included in twelve sites of the EU network NATURA 2000) belonging to different bioclimatic types were studied. The total essential-oil content is negatively related to the altitude.
