The objective of the investigations presented in this paper was to establish the frequency of the incidence of subacute acidosis in the rumen of cows (SARA) in the first three months of lactation and the possibilities for its prevention using a mineral mix based on bentonite, zeolite, magnesium oxide, and sodium bicarbonate (Mix plus). The values obtained for the rumen pH content show that subacute rumen acidosis occurs in in 20 percent of the examined cows in the early stage of lactation. For these investigations, cows in early stages of lactation were chosen and divided into 2 groups. Cows of the experimental group were administered a fodder mix which contained the mineral mix for a buffer effect (Mix plus). The average values of the rumen pH content in the control and the experimental group of cows at the beginning and on the 30th day of the experiment were approximately the same and did not differ significantly (p>0.05). On the 60th day of the experiment, the values for the electrochemical reaction of the rumen content for the control group amounted to an average of 6.219?0.18, and for the experimental group of cows it was 6.772?0.23. The obtained difference was statistically very significant (p<0.001). At the end of the experiment, on the 90th day, the average pH value of the rumen content of cows of the control group was 6.308?0.16, while this value in the experimental group of cows was significantly higher and amounted to 6.676?0.29 (p<0.01).

After high fractures of the mandibular condyle, the insufficient blood supply to the condyle often leads to poor bone and cartilage repair ability and poor clinical outcome. Parathyroid hormone (PTH) can promote the bone formation and mineralization of mandibular fracture, but its effects on cartilage healing after the free reduction and internal fixation of high fractures of the mandibular condyle are unknown. In this study, a rabbit model of free reduction and internal fixation of high fractures of the mandibular condyle was established, and the effects and mechanisms of PTH on condylar cartilage healing were explored. Forty-eight specific-pathogen-free (SPF) grade rabbits were randomly divided into two groups. In the experimental group, PTH was injected subcutaneously at 20 µg/kg (PTH (1–34)) every other day, and in the control group, PTH was replaced with 1 ml saline. The healing cartilages were assessed at postoperative days 7, 14, 21, and 28. Observation of gross specimens, hematoxylin eosin staining and Safranin O/fast green staining found that every-other-day subcutaneous injection of PTH at 20 µg/kg promoted healing of condylar cartilage and subchondral osteogenesis in the fracture site. Immunohistochemistry and polymerase chain reaction showed that PTH significantly upregulated the chondrogenic genes Sox9 and Col2a1 in the cartilage fracture site within 7–21 postoperative days in the experimental group than those in the control group, while it downregulated the cartilage inflammation gene matrix metalloproteinase-13 and chondrocyte terminal differentiation gene ColX. In summary, exogenous PTH can stimulate the formation of cartilage matrix by triggering Sox9 expression at the early stage of cartilage healing, and it provides a potential therapeutic protocol for high fractures of the mandibular condyle.

World Health Organization (WHO), cervical cancer is the number two cause of death in the world for women from all existing cancer. Every two minutes a woman dies of this disease. This cancer attack at an early stage does not cause any symptoms. That is why, why does this type of cancer fall into the category of the silent killer. One of the promotive and preventive efforts in women of childbearing age as primary prevention can be through the provision of health education about cervical cancer using the Acetic Acid Inspection (IVA) method. The purpose of this study is to find out whether there is an influence of health education about IVA on WUS motivation in cervical cancer detection in health centers. Putri Ayu Jambi. This type of quantitative research with non randomized pretest-posttest with control group design, with purposive sampling technique totaling 22 WUS, 11 people as controls and 11 experimental people. The instrument in the form of questionnaires was analyzed by univariate and bivariate Paired Test t-test, which was conducted from April to July 2018.  The results of the study revealed that of the 22 WUSs studied, the average motivation of the pretest in the experimental group was 41.1818 and the control group was 39.9091, while the results of the posttest of the experimental group after being given counseling and leaflets increased by 42.9091 with p-value 0.034. There is an influence of health education about IVA tests on WUS motivation in detecting cervical cancer. It is suggested that the Puskesmas can improve activities in planning disease control programs, especially carrying out counseling and counseling both in the puskesmas building and in the working area of the puskesmas by involving cadres in their environment so that WUS is moved to take the IVA examination.

The aim of this study was to evaluate the effect of administration of eCG and intrauterine infusion of povidone-iodine to promote the early recovery of ovary and uterus functions in early stage after delivery on postpartum beef cows. Thirty-three postpartum Japanese Black cows without retention of placenta were used for this investigation. After delivery, cows nursed colostrums to calves for several hours in a pen, and then were separated from calves and returned into a barn managed in a group. In experimental group (n = 14), on Day 10 (Day 0 = day of parturition), an intramuscular administration of 500 IU of eCG and infusion of 30 mL of 2% povidone-iodine into the uterus body were conducted. The untreated cows delivered in the same period were compared as a control group (n = 19). Cows were inseminated artificially using commercial Japanese Black frozen–thawed semen when standing oestrus was detected until Day 90. Pregnancy diagnosis was performed 30 days after insemination by ultrasonography. For all of the experimental group and 8 cows in the control group, the diameter of follicles >8 mm and the diameter of cross-section between endometrium in uterus of the implanted side at the point of ~2 cm from bifurcation of the uterus were measured using an ultrasound scanning machine connected to a 7.5-MHz convex probe. This monitoring was carried out every 10 days from Day 10 until the day of first oestrus (= insemination) or until Day 80 for non-returned oestrus cows. Data were analysed using Fisher’s exact test and ANOVA. The ratio of returned oestrus by Day 90 was 100% (14/14) in experimental group and 89.5% (17/19) in control group. The first oestrus day postpartum in the experimental group and the control group was the almost same: 52.9 ± 12.1 (24–88) days and 57.2 ± 19.9 (29–78) days, respectively. The conception rate until Day 90 tended to be higher (P = 0.07) in the experimental group (78.6%, 11/14) than in the control group (47.4%, 9/19). The days inseminated to cows that were conceived, was almost same between the experimental group (57.5 ± 18.6, 24–87 d) and the control group (55.4 ± 12.9, 36–78 d). The ratio of cows observed follicles more than 8 mm, was higher in the experimental group than control group on Day 50 (90.9% v. 50.0%; P = 0.09) and Day 60 (66.7% v. 0%; P < 0.05), respectively. The diameter of uterus tended to be lesser in the experimental group than in the control group on Day 30 (16.9 ± 2.8 mm v. 19.2 ± 2.8 mm; P = 0.09), and that regressed linearly to Day 30 in the experimental group however that was prolonged until Day 40 (16.4 ± 1.7 mm) in the control group. These results indicate that administration of eCG and uterus infusion of povidone-iodine at an early stage postpartum may promote the early recovery of ovary and uterus functions in beef cows. This research was supported by a grant from the Research Program of MAFF, (REP1004) Development of Innovative Technology for Animal Reproduction.

MATAS Hopscotchtechnique was created to solve the subtraction of three types of fractions. The study involved 56 pupils from two Year 5 classes. A quasi-experimental, nonrandomized control group, pretest-posttest delayed post-test was conducted on two intact groups, randomly assigned into control and experimental groups. A pretest was administered at the early stage of this study. The study described types of error made by the pupils in solving the subtraction of fractions. Rubrics, Hodes and Notling (1998), were used to describe types of error made by the pupils in the pretest and posttest. The findings in the pretest showed both groups made concept, directions, and careless errors. However, in the posttest, the experimental group made careless errors while the control group made concept, directions, and careless errors. The number of errors made by the control group was higher than that made by the experimental group.

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p < 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p > 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p < 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p < 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p < 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.

Bacgraund/Aim. The use of new therapeutic methods to prevent development of fibrothorax as the final complication of the human pleural infections requires research with experimental animals. The aim of this study was to standardize the procedures for the establishment of our own experimental model of empyema in rabbits, since it should be able to offer similar conditions found in human pleural infections. Methods. This experiment included 15 chinchilla rabbits, weighing from 2.3 to 2.8 kg. There were 12 rabbits in the experimental group, while 3 rabbits formed the control group. On the first day, we administered 0.4-0.5 mL of turpentine in the right pleural space of the rabbits from the experimental group in order to provoke sterile exudative pleurisy. After 24 h we injected 1 mL of Staphylococcus aureus and 1 mL of Escherichia coli bacteria in the same concentration of 4.5 x 108 bacteria/mL. Thoracocentesis for the pleural fluid analysis was performed 24, 48, 72, and 96 h after bacteria instillation. In these pleural samples we estimated the number of leucocytes and the values of lactate dehydrogenase (LDH), glucose and pH in pleural fluid, as well as the presence of bacteria. We did not protect the animals with antibiotics, and on the day 7 of the experiment they were sacrificed with the lethal dose of barbiturate (iv). The lung from the empyemic side of all experimental animals and the lung of one control animal were histopathologically examined. Results. A total of 4 animals had a small amount of clear pleural fluids or there was no fluid obtained with thoracocentesis 24 and 48 h after the bacteria instillation. after the bacteria instillation. In the remaining 8 rabbits 24 h after bacteria administration the mean values (? SD) of the parameters monitored were as follows: Le 34.75 ? 6.13 x 109/L, LDH 17,000 ? 4,69 U/L, glucose 1.23 ? 0.45 mmol/L, and pH 6.975 ? 0.15. The obtained values met the criteria for the evaluation of effusion as pleural empyema or complex and complicated pleural effusion (LDH > 1000 U/L, glucose < 2.31 mmol/L and pH < 7.20). Bacterial cultures were positive in 5 out of 8 first pleural samples and in only 2 samples after 48 h of bacteria administration. There was a positive correlation between the number of leukocytes and the LDH value (r = 0.071, p < 0.001), and a negative correlation between the number of leukocytes and the glucose level (r = 0.864, p < 0.001), and the leukocytes number and pH of the pleural fluid (r = 0.894, p < 0.001). The mean glucose value increased after 48 h (3.23 ? 0.44 mmol/L), and the pH value rose after 72 h (7.22 ? 0.03) which was beyond the empyema level. Conclusion. The creation of the experimental empyema model is a very delicate work with uncertain success. Its value and importance are crucial for pleural pathology research. With the intention to obtain a more empyemic pleural reaction we created a model with two different human pathogen bacteria. We generated the satisfactory results, but not as good as those contained in some of the reference literature data.

Abstract Purpose This study analyzed the morbidity and mortality associated with non-small cell lung cancer (NSCLC) and evaluated treatment strategies for it in a low-risk area of COVID-19 in China. Materials and methods: We selected patients admitted to Sichuan Science City Hospital from September 2019 to February 2020 and divided them into experimental and control groups. The treatment strategy was evaluated by patients’ prognosis. Results: 9,010 patients were hospitalized. The total morbidity was 0.699%, of which 0.504% was observed in the control group and 0.991% in the experimental group (P=0.024). The total mortality was 0.999/103, of which 0.630/103 was observed in the control group and 1.413/103 in the experimental group (P=0.322). Therapy discontinuation and cancer progression in the experimental group were significantly higher than the control group (P＜0.001, P=0.007). The treatment methods and prognosis were not significantly different for early-stage patients between the two groups. Late-stage patients in the experimental group experienced significantly lower percentages of non-surgical treatments (P＜0.001), higher percentages of discontinued therapies (P＜0.001), lower percentages for prognosis of wellness (P＜0.001), and higher percentages of cancer progression (P＜0.001) than the control group. Conclusion: NSCLC exhibited significantly higher morbidities during the COVID-19 pandemic. The mortality in the experimental group was slightly higher than the control group, while the difference in cancer progression was significant. It is feasible to perform surgery for early-stage NSCLC patients, and treatment should not be suspended for late-stage patients in regions with low-risk for COVID-19 infection.

In recent years, the world demand for a low fat and high protein content lean meat had increased to meet the needs of the organism in proteins. This article presents the results of an expedient scientific-research analysis on establishing the influence of Poll Dorset and Texel breed on the particular growth variability, development of both meat and wool productivity of Kazakh mutton-semifine-wool breed of sheep. Results of the study were obtained under the same grazing conditions of 110 head of purebred and 110 crossbreed Texel and Poll-Dorset sheep of second generation. It was found that peers of the experimental group exceeded their peers in the control group on the dynamics of growth in body weight (P£0.05), i.e. crossing helped to improve the performance of daily gain (P£0.05). In terms of slaughter indicators, such as the slaughter and carcass weight, crossbreed male lambs also surpassed purebred male lambs (P£0.05). Herein, it was found that crossbreed lambs of Texel breed observe the superiority in terms of meat output (fat free) in relation to purebred male lambs (P£0.01). The study of longissimus muscle chemical composition showed that crossbreed male lambs of Texel breed in protein content in this very muscle are superior to purebred peers (P£0.05). A study of wool characteristics of experimental sheep showed that at the age of 12 months the high wool clip was observed in male lambs of Texel second generation (P£0.05). The high yield of washed wool was also observed in Texel male lambs (P£0.05) as compared to purebred peers.

The objective of the investigations presented in this work was to establish the effects of a glycerol-based energy supplement in the diet of high-yield dairy cows on their body condition and production results during the early stage of lactation. Forty-seven cows were selected before calving, and they were divided into two groups: controls (n=26) and experimental (n=21). Cows of the experimental group were administered the preparation 'Energy Top' (Biochem GMBH, Germany), in a quantity of 250 ml daily during the final two weeks of the dry period and until the 60th day of lactation. The body condition score (BCS) of all cows was determined 10 days before calving, and on days 15 and 60 after calving. Blood samples were taken 10 days before and 15 days after calving, and concentrations of glucose and beta hydroxi-butyric acid (BHBA) were determined in all samples. Average daily milk production of all cows was measured on days 30 and 60 of lactation. The results showed that the differences in BCS between the dry period and puerperium, or the dry period and the 60th day of lactation, were within physiological values in the experimental group of cows, and higher than physiological values in the control group. Glucose concentration was statistically significantly higher in the experimental group than in the control group of cows 10 days before calving (p<0.05) and 15 days after calving (p<0.01). Fifteen days after calving, the BHBA concentration in the control group of cows was significantly higher (p<0.01) than in the experimental group. On days 30 and 60 of lactation, the milk yield of experimental cows was higher than of those in the control group, but the difference was not statistically significant. The obtained results indicate that energy supplements should be used as an integral part of the feed ration during the peripartal period in order to prevent changes in the body condition score of cows by more than 0.7 points, and also that, in cows with a daily milk production of up to 30 l, an energy supplement has a stimulatory effect on milk production until the establishing of an energy balance, in this case, until around the 30th day following calving. .
