Introduction. The research was conducted with the aim of determining differences in morphological characteristics, basic and specific motor abilities and karate techniques, in relation to fighting efficiency. Material and Methods. The sample of examinees consisted of group of 105 elite Croatian cadet karate athletes, aged 14-16 years. According to the contestant quality, the sample was divided into higher and lower quality karate athletes. Results. The discriminative analysis results showed that higher quality athletes were of greater body height and had significantly less fat tissue. In the area of morphological measures, the fight success, that is, the fighting efficiency, was mostly influenced by body height, in a positive sense, and subcutaneous fat tissue, in a negative sense. In the area of basic motor skills, the fight success, that is, the fighting efficiency, was mostly and dominantly influenced by agility/coordination, explosive power and speed. This very research showed that specific agility-mobility dominantly determined the fighting efficiency of cadet karate athletes. It was also possible to recognize two types of fighters, one dominated by specific technique realization speed over specific agility, and the other dominated by specific agility over specific karate technique realization speed. The second type was significantly more efficient in karate fight. The fight success, that is, the fighting efficiency, was mostly and dominantly influenced by knowledge and/or technique knowledge (Technique efficiency) that was significantly saturated by basic and specific motor abilities. Conclusion. Therefore, the optimum interrelation of karate technique performance quality, and the level of basic and specific motor abilities greatly determined the fighting efficiency of young karate athletes.

In the present, the third publication included to this volume, the main topic considers the explanation of the existence of any relations between studied variables of body build during the period of 22 months, e.g. from the beginning till the end of investigations. At that time the considerable changes related to the pubertal period took place. The results of the correlation matrix between studied variables and factor analysis for the whole material and for each gender separately are presented. It is seen that there are differences between boys and girls in the interrelation concerning studied variables and in separated latent factors. It is rather related to differences in the phase of puberty (more advanced girls than boys in this process), although the same calendar age. Girls who mature earlier are characterized by greater initial stature and greater body weight, BM I fat mass (including subcutaneous fat tissue), and fat-free mass at the beginning and end of the study than girls who mature later. However, later matured girls show, in the whole investigated period, greater increments in stature and weight than earlier matured ones (of the same calendar age). At the earlier stage of puberty (boys under study) the factor one (F I) representing body mass and its increments, is associated with final body height (at the end of study), whereas F3 is associated with initial height (at the beginning of the study). This association is reverse at the latter phase of puberty (girls under study), while F I (also representing body mass but not its increments) is associated with the initial height, whereas final height represents the separate factor (F3).

The aim of this research was to determine the trend change in the morphological features of boys aged 7 to 10, of various nutritional status, with particular emphasis on the trend of occurrence of obesity among the same population. The sample consisted of 1164 boys, divided into four sub-groups (based on their age), and then each sub-group was further divided into three groups depending on their nutritional status. Four morphological factors were measured: the longitudinal, transversal and circular dimensionality of the skeleton, body mass and subcutaneous fat tissue. They were used to determine the morphological characteristics of the participants. The data were processed using the SPSS 20.0 statistics program. To determine the dynamics of change in the increasing or decreasing continuum, a trend analysis was used. By analyzing and evaluating the results obtained during the course of this study, differences in morphological characteristics were determined between children with normal body mass, overweight children and obese children of various ages. The dynamic of the change in the aforementioned characteristics in most morphological spaces of the boys indicated a continued increase that accompanies the age of the participants. Among the participants with normal body mass and overweight participants, a discontinued form of development among the morphological characteristics was noted. The discontinued form of development is visible among obese participants in the space which refers to measuring subcutaneous fat tissue. A significantly greater annual increase in body fat, compared to the average, was also noted.

Lupus mastitis Systemic lupus erythematosus (SLE) infrequently presents itself as lupus panniculitis. In lupus panniculitis the subcutaneous fat tissue is involved in the inflammatory process. Lupus mastitis is again a rare variant of lupus panniculitis, probably caused by an immune-mediated inflammatory process. In literature on the topic we can find 30 cases of lupus mastitis in men and women. Lupus mastitis may present like a breast lesion suspected to be malignant, clinically and radiologically. In the differential diagnosis we consider inflammatory breast cancer, subcutaneous panniculitis-like T-cell lymphoma (SPTL) and diabetes mastopathy. With a medical history of SLE and signs of inflammation of the skin above the lesion however, a diagnosis of lupus mastopathy is more presumable. Medical treatment seems more indicated in lupus mastitis, because delayed healing after surgical procedures is often reported. Even though methylprednisolone and chloroquine give clinical improvement, they need to be repeated often because of a high risk of relapse.

<p><strong>Objective:</strong> Obesity is a very common and important health problem and it has become widespread all over the world. Fat tissue is one of the major endocrine organs. Subcutaneous adipose tissue is associated with many diseases such as coronary artery disease, metabolic syndrome, diabetes, impaired lipid profile. Pregnancy is a special condition with metabolic changes involving all systems. We aimed to investigate the relationship and correlation between abdominal fat and HbA1c because of the specific metabolic conditions in pregnancy.</p><p><strong>Study Design:</strong> This is a retrospective study. Ninety-nine (n=99) pregnant women between the ages of 20 and 40 were included in the present study. They have not any other chronic diseases. Ultrasonography was performed between 16.-28. weeks. Abdominal subcutaneous fat tissue was measured during 16-28 weeks of pregnancy. Routine biochemical parameters and HbA1c were evaluated.</p><p><strong>Results:</strong> Subcutaneous fat tissue had a positive correlation with metabolic parameters such as weight and BMI, and a negative correlation with vitamin D level. There is a positive strong correlation with HbA1c level. There was not any correlation between HbA1c and metabolic parameters like triglyceride, LDL, HDL, and cholesterol.</p><p><strong>Conclusion:</strong> There was a strong positive correlation between abdominal subcutaneous fat tissue thickness and HbA1c. However, we didn’t find any correlation between infant weight and metabolic parameters.</p>

The study included the progeny of three boar-sires breeds (SL - Swedish Landrace; LW - Large White and P - Pietrain). A total of 201 progeny of both sexes (93 female and 108 male castrated animals), originating from 16 boar-sires, were tested. The study included the progeny of 10 SL boar-sires (sires nuRWer: 1, 2, 3, 7, 8, 9, 15, 16, 17 and 18), progeny of 3 LW sires (sires nuRWer: 4, 5 and 6) and 3 P boar-sires (sires nuRWer 14, 19 and 20), born in four seasons (winter, spring, summer and autumn). Studies have shown that, with an mean weight of a warm carcass side of 81.20 kg, the highest mean values for ham weight (RW; 10.456 kg), mass of intermuscular fatty tissue (RINT; 0.477 kg), ham bone (RB; 0.837 kg) and muscle tissue RMT, 7,939 kg) have progeny of the sires of Pietrain breed (P) compared to SL and LW sires. In comparison to animals sired by SL and LW boars, the progeny of P sires had less skin and subcutaneous fat tissue (RSFT) by 30 and 549 grams. Studies have shown that we have progeny of sires 7 and 9 of SL breed which have the lowest LSMean values for the yield of skin and subcutaneous fat tissue (869 and 876 g), which is below the mean for breed by 364 and 357 g. In addition, when it comes to intermuscular fatty tissue, the lowest established value was recorded in the progeny of sire no. 8 of SL breed (182 g), which is by 220 g less than the general mean and by 132 g below the mean of the sire breed. The animals originating from sires n. 19 and 20 showed the highest weight of muscle tissue (RMT) (8.489 and 8.118 kg) in the ham, which is by 2.853 and 2.482 kg more meat compared to the progeny of sire no. 5 of LW breed. The total weight of the ham and the ham muscle yield were influenced by (P <0.01 and P <0.001) sire breed, sires within the breed, gender and season of birth. A very significant (P <0.001) influence of the weight of warm carcass sides on the ham weight and tissue yield was determined.
