Metabolic remodeling of visceral and subcutaneous white adipose tissue during reacclimation of rats after cold
No full textDeciphering lipid metabolism in white adipose tissue (WAT) depots during weight gain is important to understand the heterogeneity of WAT and its roles in obesity. Here, we examined the expression of key enzymes of lipid metabolism and changes in the morphology of representative visceral (epididymal) and subcutaneous (inguinal) WAT (eWAT and iWAT, respectively) - in adult male rats acclimated to cold (4±1 °C) for 45 days and reacclimated to room temperature (RT, 22±1 °C) for 1, 3, 7, 12, 21, or 45 days. The relative mass of both depots decreased to a similar extent after cold acclimation. However, fatty acid synthase (FAS), glucose-6-phosphate dehydrogenase (G6PDH), and medium-chain acyl-CoA dehydrogenase (ACADM) protein level increased only in eWAT, whereas adipose triglyceride lipase (ATGL) expression increased only in iWAT. During reacclimation, the relative mass of eWAT reached control values on day 12 and that of iWAT on day 45 of reacclimation. The faster recovery of eWAT mass is associated with higher expression of FAS, acetyl-CoA carboxylase (ACC), G6PDH, and ACADM during reacclimation and a delayed increase in ATGL. The absence of an increase in proliferating cell nuclear antigen suggests that the observed depot-specific mass increase is predominantly due to metabolic adjustments. In summary, this study shows a differential rate of visceral and subcutaneous adipose tissue weight regain during post-cold reacclimation of rats at RT. Faster recovery of the visceral WAT as compared to subcutaneous WAT during reacclimation at RT could be attributed to observed differences in the expression patterns of lipid metabolic enzymes.M223.

A new dwarf schendylid centipede (Chilopoda: Geophilomorpha: Schendylidae) with a low number of legs from Serbia, Balkan Peninsula
No full textSchendyla antici sp. nov., a dwarf geophilomorph from the Mt. Medvednik (Western Serbia, Balkan Peninsula), is described and illustrated based on the specimens extracted from the soil samples. A detailed comparison with all species within the genus is provided. The new species has the lowest number of leg-bearing segments within the genus Schendyla Bergse & Meinert, 1866, and one of the lowest in the order Geophilomorpha in general.M230.94014185419

A review of the genus Vitrea Fitzinger, 1833 (Gastropoda, Eupulmonata, Pristilomatidae) in Serbia: diversity, distribution and the description of a new species
No full textIn this paper, the genus Vitrea Fitzinger, 1833 in Serbia is reviewed. All previous literature data on this genus from Serbia are summarised and used to discuss its distribution in the country and create distribution maps, supplemented by new material collected by the authors. All Serbian species are figured. For each species, a brief description of the examined specimens, data on previous findings in Serbia, the material (including types) that were analysed, the distribution and habitats in Serbia they inhabit, as well as remarks on specific species are given. A new species, Vitreavirgo Gojšina & Dedov, sp. nov., is described from a pit on Mt. Devica in eastern Serbia. Vitreapygmaea (O. Boettger, 1880) is reported for the first time for the territory of Serbia. As some Vitrea species have a narrow geographical range and prefer certain habitats, they are particularly vulnerable to habitat changes, which is also discussed in the paper. An identification key for all hitherto known Serbian species is given.M221.3245273120
