Burmese Cretaceous amber (∼99 Ma, Myanmar) is famous for the preservation of a wide range of fauna and flora, including representatives of marine, freshwater and terrestrial groups. Here, we report on three ostracod specimens, that came visible as syninclusions to an aquatic isopod. The three specimens represent three different taxa, that were found preserved in a single piece of amber. One of the described specimens was studied using µCT scanning data. On the basis of general carapace morphology we assign all three to the group Podocopida, and (tentatively) its ingroup Cypridocopina. A lack of visibility of more particular diagnostic features such as adductor muscle scars and details of the marginal zone precludes a further identification, but we discuss possible affinities with either the marine-brackish group Pontocypridoidea or the non-marine group Cypridoidea. The taphonomy indicates that the studied ostracods had been subject to limited (if any) post-mortem transport, which could be consistent with marginal marine environments.

The aim of this study was to determine whether glycolytic potential (GP) in pork muscle could be modified by the availability of carbohydrates in the diets and, if so, to what extent meat color and drip loss were affected. Biopsy samples of longissimus muscle (LM) from 48 Swiss Large White pigs (25 gilts, 23 barrows) weighing 70 kg were collected, and the GP was determined to vary from 111 to 187 μmol g-1 wet weight. At 90-kg body weight, pigs were moved into individual pens and assigned (blocked by GP and sex) to be fed 2.8 kg of a diet either high (H) or low (L) in available carbohydrate up to 104 kg. Pigs were fasted overnight (15 h) before slaughter. Glycogen, glucose, glucose-6-phosphate and lactic acid content were determined in samples of LM (predominantly glycolytic muscle) collected 30 min and 24 h post-mortem and in samples of the dark part of the semitendinosus (ST, oxidative part of the muscle) 24 h post-mortem. After slaughter, the decline in pH and temperature was recorded in the LM from 30 min to 24 h after bleeding. Regardless of the diet, content of glycolytic intermediates and lactic acid were higher in the LM compared to the ST. Diet did not alter the GP, and did not affect color or drip loss of the LM. However, in gilts fed the H diet muscle pH was lower by 0.2 units from 30 min until 6 h post-mortem than in gilts fed the L diet. These effects were not observed in barrows. ST of gilts fed the H diet had higher levels of glycolytic intermediates and lactic acid and, therefore, higher GP compared to gilts on the L diet, but no dietary effects occurred in barrows. Increased GP resulted in paler color and higher drip loss, whereas ultimate pH was not affected. The GP was positively correlated with L* (0.52), a* (0.49), b* (0.59) and drip loss (0.77) of the ST, whereas poor correlations were observed in the LM. In conclusion, dietary treatment only affected paleness and drip loss of the ST muscle and the effects were more pronounced in gilts than barrows. Increased GP resulted in paler meat with higher drip loss. Key words: Pig, glycolytic potential, meat quality, carbohydrate supply

1. Post-mortem changes in the concentrations of the following compounds in ox sternomandibularis muscles stored in nitrogen at 1°, 5° and 15° are reported: Pi creatine phosphate, hexose monophosphates, fructose diphosphate, triose phosphates, α-glycerophosphate, phosphoglycerates, lactate, ATP, ADP, AMP, NAD+ and total nucleotides. Some results obtained with muscles stored at 37° are included. 2. At the time the muscles were placed at controlled temperatures (about 1·5hr. post mortem) the phosphorus in the compounds measured accounted for 91±6% (s.d.) of the total acid-soluble phosphate. 3. The results indicated that at all temperatures the activities of the phosphorylase and phosphofructokinase steps limited the rate and the extent of post-mortem glycolysis. 4. The large variations in hexose monophosphate concentrations during storage indicated that the ratio of phosphorylase to phosphofructokinase activity varied considerably with time and temperature. 5. Between 3·5 and 7hr. post mortem the rates of glycolysis and of ATP turnover were not slower at 5° that at 15°, and were probably faster at 1°. The significance of this finding is discussed.

Means Of Transmission

The deleterious effect of post mortem degeneration results in a progressive loss of ultrastructural detail. This had led to reluctance (if not refusal) to examine autopsy material by means of transmission electron microscopy. Nevertheless, Johannesen has drawn attention to the fact that a sufficient amount of significant features may be preserved in order to enable the establishment of a definitive diagnosis, even on “graveyard” tissue.Routine histopathology of the autopsy organs of a woman of 78 showed the presence of a well circumscribed adenoma in the anterior lobe of the pituitary. The lesion came into close apposition to the pars intermedia. Its architecture was more compact and less vascular than that of the anterior lobe. However, there was some grouping of the cells in relation to blood vessels. The cells tended to be smaller, with a higher nucleocytoplasmic ratio. The cytoplasm showed a paucity of granules. In some of the cells, it was eosinophilic.

History Of

Die Geschichte des sackförmigen oder fusiformen Aneurysmas reicht in die Zeit der alten Ägypter, Byzantiner und Griechen zurück. Vesal 1557 und Harvey 1628 führten den Begriff in die moderne Medizin ein, indem sie bei je einem Patienten einen pulsierenden Tumor intra vitam feststellten und post mortem verifizierten. Weitere Eckpfeiler bildeten die Monographien von Lancisi und Scarpa im 18. bzw. beginnenden 19. Jahrhundert. Die erste wirksame Therapie bestand in der Kompression des Aneurysmasacks von außen, die zweite in der Arterienligatur, der John Hunter 1785 zum Durchbruch verhalf. Endoaneurysmoraphie (Matas) und Umhüllung mit Folien wurden breit angewendet, bevor Ultraschalldiagnostik und Bypass-Chirurgie Routineverfahren wurden und die Prognose dramatisch verbesserten. Die diagnostischen und therapeutischen Probleme in der Mitte des 20. Jahrhunderts werden anhand von zwei prominenten Patienten dargestellt, Albert Einstein und Thomas Mann, die beide im Jahr 1955 an einer Aneurysmaruptur verstarben.
