Neuroprotection from inflammation: Experimental allergic encephalomyelitis facilitates traumatic spinal cord injury recovery
Passive immunization with T cells activated against central nervous system (CNS) - associated myelin antigens has been found to provide neuroprotection following CNS trauma, leading to the concept of protective autoimmunity. However, limited research exists about whether actively induced CNS autoimmunity may offer any similar benefit. In this study, the kinetics and the effect of endogenously anti-myelin activated T cells following spinal cord injury (SCI), were investigated. Experimental allergic encephalomyelitis (EAE) was actively induced in Lewis rats following immunization with myelin basic protein (MBP). In vivo 5-Bromo-2-deoxyuridine (BrdU) incorporation from activated T cells was used as a marker of T cell- proliferation. BrdU was injected on 5th, 6th and 7th day post-induction (DPI) at all EAE-animals. On DPI 8, spinal cord compressive injury was induced by a transient extradural application of an aneurysm clip at the T8 spinal level. SCI resulted in spastic paralysis of hindlimbs, in all but sham-injured animals. Recovery from SCI was significantly better in EAE-animals. Activated mononuclear cells were selectively accumulated at the site of the injury. Axonal loss was less in the EAE group following SCI. Our findings indicate that actively induced autoimmunity against CNS myelin antigens may protect spinal cord pathways from mechanical injury

A Modified Technique for Laparoscopic Spleen Preserving Distal Pancreatectomy
Spleen preserving laparoscopic distal pancreatectomy is considered as first choice operation for symptomatic benign or small malignant lesions located at the body or tail of the pancreas. The two main surgical techniques that have been proposed and widely adopted for spleen preserving laparoscopic distal pancreatectomy are the Warshaw and Kimura techniques. A novel modified approach for laparoscopic spleen preserving distal pancreatectomy is presented. The technique was initially performed in a 57-year-old female patient with mucinous cystadenoma. Following the surgical planes created by the fascia fusion and the organ rotation during embryogenesis (fascia of Toldt and renal fascia) with the patient in a right lateral decibutus position, the tumor was accessed retroperitoneally, without dividing the gastrocolic ligament and entering the lesser sac. The tail of the pancreas was mobilized anteriorly and medially, the lesion was visually identified and resected, and short gastric and left gastroepiploic vessels were preserved. We present the technical details and tips; we define the surgical anatomy of it and discuss the perioperative course of the patient as well as the possible benefits of the proposed technique. The proposed technique seems to be safe, easy to perform, and may present a promising alternative approach for patients with pancreatic disease that can be treated by laparoscopic pancreatectomy

UNDERWATER STROKE KINEMATICS DURING BREATHING AND BREATH-HOLDING FRONT CRAWL SWIMMING
The aim of the present study was to determine the effects of breathing on the three - dimensional underwater stroke kinematics of front crawl swimming. Ten female competitive freestyle swimmers participated in the study. Each subject swam a number of front crawl trials of 25 m at a constant speed under breathing and breath-holding conditions. The underwater motion of each subject's right arm was filmed using two S-VHS cameras, operating at 60 Hz, which were positioned behind two underwater viewing windows. The spatial coordinates of selected points were calculated using the DLT procedure with 30 control points and after the digital filtering of the raw data with a cut-off frequency of 6 Hz, the hand's linear displacements and velocities were calculated. The results revealed that breathing caused significantly increases in the stroke duration (t9 = 2.764; p < 0.05), the backward hand displacement relative to the water (t9 = 2.471; p<0.05) and the lateral displacement of the hand in the X - axis during the downsweep (t9 = 2.638; p < 0.05). On the contrary, the peak backward hand velocity during the insweep (t9 = 2.368; p < 0.05) and the displacement of the hand during the push phase (t9 = -2.297; p < 0.05) were greatly reduced when breathing was involved. From the above, it was concluded that breathing action in front crawl swimming caused significant modifications in both the basic stroke parameters and the overall motor pattern were, possibly due to body roll during breathin

The Use of Lupin as a Source of Protein in Animal Feeding: Genomic Tools and Breeding Approaches
Livestock production in the European Union EU is highly dependent on imported soybean, exposing the livestock farming system to risks related to the global trade of soybean. Lupin species could be a realistic sustainable alternative source of protein for animal feeding. Lupinus is a very diverse genus with many species. However, only four of them—namely, L. albus, L. angustifolius, L. luteus and L. mutabilis—are cultivated. Their use in livestock farming systems has many advantages in relation to economic and environmental impact. Generally, lupin grains are characterized by high protein content, while their oil content is relatively low but of high quality. On the other hand, the presence of quinolizidine alkaloids and their specific carbohydrate composition are the main antinutritional factors that prevent their use in animal feeding. This research is mainly related to L. albus and to L. angustifolius, and to a lesser extent, to L. lauteus and L. mutabilis. The breeding efforts are mostly focused on yield stabilization, resistance to biotic and abiotic stresses, biochemical structure associated with seed quality and late maturing. Progress is made in improving lupin with respect to the seed quality, as well as the tolerance to biotic and abiotic stress. It has to be noted that modern cultivars, mostly of L. albus and L. angustifolius, contain low levels of alkaloids. However, for future breeding efforts, the implementation of marker-assisted selection and the available genomic tools is of great importance
