The “Patagonian Sheepdog” is a local working dog breed that was produced by selection from European working sheepdogs that arrived in the Magallanes region of southern Chile in the late nineteenth and early twentieth centuries. Currently, the Patagonian Sheepdog is most commonly found in the Chilean Patagonian region (43°12’ S to 56°30’ S), where it plays a fundamental role as a working dog in sheep and, to some extent, in cattle farming. Dog types that may have contributed to the Patagonian Sheepdog include the Old Welsh Grey and other old UK herding dogs. The modern Patagonian Sheepdog has been selectively bred by local sheep farmers to produce a herding dog that is well adapted to the area: a medium body size, long or semi-long fur, drooping or semi-erect ears, a docile character, and a great aptitude for sheep herding. Morphological studies have determined the body measurements, zoometric indices, coat color, and marking for Patagonian Sheepdogs. The objective of this investigation was to collect historical information related to the presence of this dog in Chilean Patagonia, providing general aspects of the morphology and behavior, all key factors for the recognition and conservation of this little-known herding dog.

The aims of this reseach were both to identification of coat color and to characterization several body measurements of Bali cattle male categorized in three types of age which reared in traditional farming system. The study conducted by using survey observatory method with total of  154 tails of beef cattle using for coat color identification and 29 tails of male Bali cattle were measured. Observed variables were coat color, chest circumference, shoulder height and body lenght. The data obtained were analyzed descriptively. The results showed that the distribution of Bali cattle with normal coat color was 100 %, but if diveded into native and unnative color then the frequencies were 64 % and 36 % respectively. The average rate of chest circumference, shoulder height and body lenght of male Bali cattle respectively were follows  108.47, 86.92, and 84.07 cm for Io ; 120.62, 96.98, dan 96.61 cm for I1 ; and 144.75, 116.93, and 112.22 for I2 cm. The body size of male Bali cattle is still relatively low and does not meet the quality standards of good beef cattle.

Abstract Background An exploratory field research was conducted in northwestern Ethiopia, to characterize the morphological features of Arab and Oromo goat populations as an input to design community-based breeding programs. Ten qualitative and nine quantitative traits were considered from 747 randomly selected goats. All data collected during the study period were analyzed using R statistical software. Results Plain white coat color was predominantly observed in Arab goats (33.72%) while plain brown (deep and light) coat color was the most frequent in Oromo goats (27.81%). The morphometric measurements indicated that Oromo goats have significantly higher body weight and linear body measurements than Arab goats. Positive, strong and highly significant correlations were obtained between body weight and most of the body measurements in both goat populations. The highest correlation coefficients of chest girth with body weight for Arab (r  =  0.95) and Oromo (r  =  0.92) goat populations demonstrated a strong association between these variables. Live body weight could be predicted with regression equations of y  =  − 33.65  +  0.89  ×  for Arab goats (R2  =  90) and y  =  − 37.55  +  0.94  ×  for Oromo goats (R2  =  85), where y and x are body weight and chest girth, respectively, in these goat types. Conclusions The morphological variations obtained in this study could be complemented by performance data and molecular characterization using DNA markers to guide the overall goat conservation and formulation of appropriate breeding and selection strategies.

Abstract Background: An exploratory field research was conducted in Northwestern Ethiopia, to characterize the morphological features of Arab and Oromo goat populations as a first step to design breeding programs. Ten qualitative and nine quantitative traits were considered from 747 randomly selected goats. All data collected during the study period were analyzed using R statistical software, version 3.5.2, 2018. Results: Plain white coat color was predominantly observed in Arab goats (33.72%) while plain brown (deep and light) coat color was the most frequent in Oromo goats (27.81%). The morphometric measurements indicated that Oromo goats have significantly (P < 0.001) higher body weight and linear body measurements than Arab goats. Positive, strong and highly significant (P < 0.001) correlations were obtained between body weight and most of the body measurements in both goat populations. The highest correlation coefficients of chest girth with body weight for Arab (r = 0.95) and Oromo (r = 0.92) goat populations demonstrated a strong association between these variables. Live body weight could be predicted with regression equations of y = -33.65 + 0.89x for Arab goats (R2 = 90) and y = -37.55 + 0.94x for Oromo goats (R2 = 85), where y and x are body weight and chest girth, respectively, in these goat types. Conclusions: The morphological variations obtained in this study could be complemented by performance data and molecular characterization using DNA markers to guide the overall goat conservation and formulation of appropriate breeding and selection strategies.

AbstractSkin is the body’s first barrier against external pathogens that maintains the homeostasis of the body. Any serious damage to the skin could have an impact on human health and quality of life. Tissue engineering aims to improve the quality of damaged tissue regeneration. One of the most effective treatments for skin tissue regeneration is to improve angiogenesis during the healing period. Over the last decade, there has been an impressive growth of new potential applications for nanobiomaterials in tissue engineering. Various approaches have been developed to improve the rate and quality of the healing process using angiogenic nanomaterials. In this review, we focused on molecular mechanisms and key factors in angiogenesis, the role of nanobiomaterials in angiogenesis, and scaffold-based tissue engineering approaches for accelerated wound healing based on improved angiogenesis.

In summarizing the findings of this paper it may be said that degenerative changes have been noted in practically every parenchymatous organ. Among these the most striking has been that of serous imbibition by the most active cells of these organs. In regard to the changes in the glands of internal secretion, the findings corroborate the statements of Cushing in regard to hypophysectomy, that removal of one gland of internal secretion results in changes in all the other glands. In this case, degenerative changes predominate in the hypophysis, thymus, ovary, and testis, while hyperplasia is seen in the islands of Langerhans and the medullas of the adrenal glands. Finally, in the rabbit athyroidism is responsible for grave degenerative changes in practically all organs and tissues of the body, and many of the symptoms of cretinism have an anatomical basis in organic cellular changes.

One hundred and thirty rabbits were used to evaluate the effect of genotype, gestation length, season, parity and sex on growth traits of two breeds of rabbit and their crosses. The rabbit used for the experiment were breeds of the New Zealand White (NZW) and Chinchilla (CH) breed. Six breeding bucks (three/breed) and eighteen breeding does (nine/breed) served as the foundation stock. Traits measured include: body weight (BW), nose to shoulder length (NTS), shoulder to tail length (STL), heart girth (HG), trunk length (TL) and length of ear (LE). Results revealed that, BW of the rabbits were influenced (p<0.05) by genotype, gestation length and season. CH x (CH x NZW) progenies had better BW at 35-d and 49-d of age while NZW x CH progenies had better BW at 21-d of age. Kittens born late (32-34 days) had better BW at 21-d, 35-d and 49-d while kittens kindled during early dry season had better BW at 21-d, 35-d and 49-d. Genotype affected (p<0.05) all the body measurements at 21-d, 35-d and 49-d. Gestation length affected (p<0.05) all the body measurements except for NTS at 21-d and HG at 49-d respectively. Season of birth also influenced (p<0.05) all the body measurements except for LE 21-d. Parity and sex had no effect (p>0.05) on BW, NTS, STL, HG, TL and LE. It was concluded that genotype, gestation length and season influenced BW and body dimensions of the two breeds of rabbit and their crosses while parity and sex had no effect.

Dragonfly Species

Urothemis edwardsii is one of the most threatened dragonfly species in the Mediterranean. Recent investigations and conservation efforts have increased the local geographic distribution of the species in Northeast Algeria, where a new population (named El Graeate) has been discovered. In the absence of information about the biology and behavior of U. edwardsii in this new site, a study was conducted on the emergence ecology of the species taking into account the temporal pattern of emergence, sex ratio, body size and microhabitat selection. Emergence, which was quite asynchronous, lasted for 50 days, with 50% of the population emerging within the first half of the period. Sex ratio at emergence was slightly female biased despite the absence of sexual size dimorphism, suggesting that size is not the only driving force behind mortality bias during the larval stage. There was a slight seasonal increase in the body size of exuviae (exoskeletons) in both sexes. Microhabitat selection, assessed as the vertical stratification of exuviae at ecdysis, was positively correlated with the height of supporting plants, but the relationship reached a plateau suggesting that there are predetermined limits to the vertical distribution of exuviae. These data will be essential for the future species protection, restoration and management attempts in the region.

Man and nature is a unity between body and individual in behavior. Humans are liberty, creative, happy subjects in behavior and labor. By behavior and labor, humans produce tools, spare parts, machines, and robots to replace internal organs, lengthen the senses, and lengthen defective body parts. Evolution is no longer a mutation in the body but the assembly of accessories into organs, senses, and body parts when needed. People use devices that are manufactured to be used for what people want depending on specific conditions and circumstances. Labor and behavior make objectification of people, but alienated behavior and alienated labor make humanize the object. The time to enjoy liberty, creativity, and happiness is human, and the time to perform alienated behavior and alienated labor is the time to live for the non-human. People are corrupted into slavery to standards, money. It is the process of self-torture, torturing oneself; and the nobility of standards, the wealth of money is the unhappy product of life. Humans are liberty, creative and happy subjects; alienated human beings are all helpless, unhappy, deceit. Money, standards are products of helplessness, unhappiness, lies. Standards, money remove people from life.

Aim. To study the advantages of ultrasound versus anthropometric assessment of muscle mass for early diagnosis of sarcopenia in patients >45 years of age.Material and methods. The study included 79 patients aged 4589 years with coronary artery disease (CAD), hypertension, type 2 diabetes, heart failure, class 1-3 obesity. Diagnosis of hypertension was carried out according to the European (2018) and Russian (2019) guidelines; CAD — according to Russian Society of Cardiology (2020) guidelines. Sarcopenia was diagnosed according to 2010 European Working Group on Sarcopenia in Older People (EWGSOP) criteria and 2018 EWGSOP2 guidelines. Muscle mass (MM) was determined by two methods: 1 — by measuring the rectus abdominis muscle (RAM) thickness using the ultrasound; 2 — by measuring the arm and lower leg circumference. Muscle strength was determined by wrist dynamometer. Muscle function was assessed using the 4-m gait speed test.Results. The study showed that in patients aged >45 years admitted to the emergency cardiology department, the body mass index exceeded 25 kg/m2 in 88,6% of cases. The incidence of sarcopenia of varying severity was 55,7% (n=44). The differences in RAM thickness, arm and lower leg circumference between the groups of patients with/without sarcopenia were significant (p<0,001), but were less than the threshold only for RAM thickness. RAM thickness levels progressively decreased with increasing severity of sarcopenia and significantly differed at all stages compared to patients without sarcopenia (p<0,001), regardless of body mass index. A decrease in lower leg circumference below the threshold values determining a MM decrease was observed only in severe sarcopenia, and arm circumference — in both men and women only in severe sarcopenia. There were no significant differences for arm and lower leg circumference depending on sarcopenia stages in overweight and obese patients.Conclusion. MM assessment by measuring RAM thickness with ultrasound in comparison with the anthropometric method makes it possible to diagnose sarcopenia in patients >45 years of age with cardiovascular diseases and obesity at earlier stages and to promptly recommend preventive measures.
