The authors determined the impact of carcass weight, genotype, sex, and nutrition on the degree of musculature and subcutaneous fattening as well as the level of intramuscular fat in fatteners obtained from market purchase. From among the examined weight groups, carcasses of heavy fatteners were characterized by poorer meatiness, thicker back fat and greater muscle fat content. The evaluation of the examined fattener genotypes revealed a significantly greater fattening of the muscles of crossbreds with 50% proportion of boars of the Duroc breed and purebred pigs than three- and four-breed fatteners obtained using Hampshire and Pietrain breeds. The investigations confirmed better musculature and lower fat content of gilts in comparison with hogs. Moreover, the performed experiments also showed a significant influence of traditional feeding on the reduction of meatiness and increased fattening in comparison with the animals which were fed Grower and Finisher mixtures.

The possibility of local reduction of subcutaneous fatty tissue was investigated in the project discussed in this article. Only one male participated in the experiment. During the experiment the participant trained his abdomen doing additional cardio training for two weeks, while in the following two weeks the abdomen was not trained at all. Instead of abdomen training, only cardio training was performed. This was repeated until the end of the experiment which lasted 9 weeks. The sum of thickness of all 7 observed skin folds was counted. Then, percentage of thickness of abdomen skin folds in relation to all skin folds was calculated. Each successive measurement was compared with the previous one to assess the decrease or increase of abdomen skin fold percentage in relation to all measured skin folds. We put the decreases and increases into a contingency table and calculated probability by using the Fisher’s exact test. Statistical significance was determined at 0.05 level. The local reduction of subcutaneous fatty tissue at abdomen was proven. However, the problem needs more scientific results to conclude this question completely.

Although stem cells are present in various adult tissues and body fluids, bone marrow has been the most popular source of stem cells for treatment of a wide range of diseases. Recent results for stem cells from adipose tissue have put it in a position to compete for being the leading therapeutic source. The major advantage of these stem cells over their counterparts is their amazing proliferative and differentiation potency. However, their pancreatic lineage transdifferentiation competence was not compared to that for bone marrow-derived stem cells. This study aims to identify an efficient source for transdifferentiation into pancreatic islet-like clusters, which would increase potential application in curative diabetic therapy. The results reveal that mesenchymal stem cells (MSC) derived from bone marrow and subcutaneous adipose tissue can differentiate into pancreatic islet-like clusters, as evidenced by their islet-like morphology, positive dithizone staining and expression of genes such as Nestin, PDX1, Isl 1, Ngn 3, Pax 4 and Insulin. The pancreatic lineage differentiation was further corroborated by positive results in the glucose challenge assay. However, the results indicate that bone marrow-derived MSCs are superior to those from subcutaneous adipose tissue in terms of differentiation into pancreatic islet-like clusters. In conclusion, bone marrow-derived MSC might serve as a better alternative in the treatment of diabetes mellitus than those from adipose tissue.

Materiał do przeprowadzonej analizy statystycznej stanowiły dane liczbowe dotyczące ptaków odchowywanych w ogólnie zalecanych dla danego gatunku warunkach do wieku: kurczęta i kaczki - 8, gęsi - 12, indory - 24, a indyczki - 16 tygodni. Do analizy rzeźnej pobrano próby o liczebności od 36 do 100 osobników w obrębie poszczególnych gatunków (płeć w stosunku 1:1). Obliczono oddzielnie dla samców i samic współczynniki korelacji prostej między masą następujących tłuszczów: podskórnego ze skórą, międzymięśniowego i z jamy ciała - sadełkowego i okołojelitowego. Największą współzależność stwierdzono między łączną masą skóry z tłuszczem podskórnym i międzymięśniowym a masą tłuszczu sadełkowego (r od 0.607 u kurek do 0.825 u indyczek).
