Perivascular wall tumors (PWTs or haemangiopericytomas) are common in dogs, and they are clinically important in veterinary oncology, but there is no data on the occurrence of these tumors in dogs in Poland. The aim of the present study was an epidemiological analysis of canine perivascular wall tumors. The study included 136 dogs with recognized PWTs (whose frequency of occurrence was the same in females and males). The mean age of the dogs was 9.8±3.0 years, with no statistically significant difference between sexes. Among the dogs, 40.7% were mongrels, and 59.3% were purebred. Among the purebred dogs, 21 (26.3%) were German Shepherds, 17 (21.3%) were Boxers, 5 (6.3%) were Doberman pinchers and Rottweilers. Statistical analysis revealed that four breeds were predisposed to perivascular wall tumors in comparison to the general dog population: German Shepherds, Boxers, Doberman pinchers and Rottweilers. Moreover, large-breed (but not giant-breed) dogs were shown to be predisposed to PWTs. Tumors were located in the skin or subcutis of the entire body, mostly on the legs, more seldom on the trunk or the head. The most typical location for PWTs was the elbow area (11% of all cases).

1. A survey and. statistical analysis of the records of litters born in the N.I.R.D. herd of Large White pigs over a period of 16 years are presented.2. The mean length of gestation was 114 days for both gilts and sows.3. The mean numbers of pigs born alive and born dead per litter from gilts, 10·0 and 0·2 respectively, were both significantly smaller than the corresponding figures for sows, 11·8 and O·8. No seasonal differences were found.4. The mean total losses of pigs from birth to weaning at 8 weeks were 29·5% of pigs born alive. The losses in litters from gilts, 23·0%, were significantly smaller than in litters from sows, 31·0%. The losses during the winter months both for gilts, 32·5%, and for sows, 35·9%, were significantly higher than during the summer months, 19·4% and 26·7% for gilts and sows respectively.5. Over 50% of the total losses were due to crushing by the dam, 74·1% of the losses from this cause occurring during the first 48 hr. after birth.6. The mean number of pigs weaned per litter was 8·0. The difference between the number weaned per litter from gilts, 7·7, and per litter from number of pigs was weaned per litter from sows during the summer months, 8·7, than during the winter months, 7·4.7. There was no significant difference between the number of male and of female pigs weaned.8. The mean weight at weaning was 29·9 lb., male pigs, 30·3 lb., being significantly heavier than females, 29·51b. Pigs in litters from gilts, 27·81b., were significantly lighter at weaning than those from sows, 30·0 lb., and for both gilts and sows, pigs reared during the summer months, 29·7 and 31·8 lb. respectively, were significantly heavier than those reared during the winter months, 25·9 and 28·2 lb. respectively.

The use of novel stimuli for obtaining nasalance measures in young children was the focus of this study. The subjects were 20 children without a history of communication disorders and 20 children at risk for velopharyngeal insufficiency (VPI). Each subject recited three passages; the standard Zoo Passage, and two novel stimuli that were named the Turtle Passage and the Mouse Passage. Like the Zoo Passage, the Turtle Passage contained no normally nasal consonants. The Mouse Passage was about 11% nasal consonants, which is similar to the Rainbow Passage. Statistical analysis showed no significant difference between the mean nasalance for the Zoo Passage and the Turtle Passage for either the subjects without risk of VPI (15.4% vs 15.7%) or for those at risk (30.4% vs 28.8%). Nasalance measures for the Mouse Passage were significantly higher than for either the Zoo Passage or the Turtle Passage. Listeners rated the stimuli on a 5-point equal-appearing intervals scale. The correlation coefficient between listener judgments of hypernasality and nasalance was significant for the Zoo Passage (r = 0.70) and for the Turtle Passage (r = 0.51) but not significant for the Mouse Passage (r = 0.32). Using cut-off scores of 22% for nasalance and 2.25 for hypernasality, the sensitivity for the Zoo Passage was 0.72, and for the Turtle Passage, 0.83.

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

This study aims to examine the variability of rainfall and temperature based on spatio-statistical analysis. Data for the study was gotten from the Nigerian Meteorological Agency and subjected to statistical analysis using mean, standard deviation, time series analysis, t-test and correlation. The results of the study revealed that the mean rainfall in the area is 108.6 mm, mean temperature is 28o C and mean sunshine is 4.7 hours. The result further revealed that mean onset date in the state is 13th march, mean cessation date is 10th October while the mean length of rainy season is 223 days. The result also showed that rainfall anomaly index in the area ranged between -2.12 and 2.28 while temperature anomaly ranged between -2.31 and 1.73.  The correlation coefficient showed that cessation (0.408) and Length of rainy season (0.406) is significantly related to rainfall, sunshine hours (0.380) and Average temperature (0.867) is significantly related to minimum temperature, sunshine hours (-0.389) and average temperature (0.749) is significantly related to maximum temperature while onset (-0.642) and cessation (0.509) is significantly related to length of rainy season. However,there is a significant difference in onset dates, cessation dates and length of rainy season in the area. The area is experiencing a significant increase in temperature, rainfall and sunshine hours and recommends that more tress should be planted in the area and Nigerian meteorological agency should also inform farmers about the onset of the rains so as to help the farmers prepare for the planting season.

Introduction There is currently little research regarding optimum patient position for venous insufficiency assessment although standing is considered the gold standard in many professional guidelines. Some patients are unable to stand for the examination and scanning patients in a standing position is physically challenging for the sonographer. This pilot study aimed to evaluate the effect of varying patient positioning on the duration of venous reflux. Method Venous reflux duration was measured in symptomatic participants with suspected venous insufficiency. Measurements were taken in the standing position (gold standard) and four alternative positions: 25° reverse-Trendelenburg (RT) tilt, sitting on the edge of the examination couch, 10° RT tilt and 0° RT tilt. The mean reflux duration measured in each different position was compared with the gold standard. Results Complete measurements were obtained from 16 patients (8 men and 8 women). For an incompetent vein, statistical analysis demonstrated a significant difference only between the standing position and the 0° position ( U = 19.0; exact P < 0.01 [2-tailed]). Conclusion Results suggest that several alternative positions could be used for assessing incompetent veins as long as the patient is not lying supine with 0° tilt. This would offer much greater flexibility, which may be of benefit to both patients and sonographers.

Abstract Dam construction is one of the most popular solutions for managing water resources. In recent years, changes in patterns of regional seismicity associated with large impoundment dams have raised concerns among environmentalists. In this study, five large dams located in Iran were studied from this perspective. The Gutenberg-Richter, linear regression and T-test were used to examine the seismic changes in the radius of 100 km of each of the dams during a twenty-five-year period before and after the construction of the dams. The results revealed that the seismicity level and relative density of large and small earthquakes in three of these dams have increased after dam construction. A significant difference between the magnitude of earthquakes, as well as the number of earthquakes before and after the construction of dams in the region, was recognized. However, the results of the T-test statistical analysis indicated that the mean depth of the earthquakes and their distance from the dams before and after construction have not changed significantly. Overall, these results indicated that the construction of large impoundment dams has been associated with some changes in patterns of regional seismicity. The findings would guide researchers to further investigate the type of impacts that dam construction may have on seismicity patterns.

Background: Certain plants stimulate spermatogenesis and increase fertility; in contrast, some plants arrest the spermatogenesis cycle. Ceratonia siliqua is an herb plant with a strong antioxidant property. The aim of this study was to evaluate the effects of carob fruit extract on spermatogenesis, testicular apoptosis, and oxidative stress in adult male mice. Methods: Forty adult male mice were randomly divided into five groups: control, sham, and carob 1–3. The sham group was injected with normal saline and the carob 1–3 groups were injected with 200, 400, and 800 mg/kg of the carob fruit extract intraperitoneally for 14 days, respectively. At the end of the injection period, spermatogenesis, testicular apoptosis, and oxidative stress were examined. Results: The sperm parameters increased in the mice that received 200 mg/kg of carob compared to the sham group (p <0.05). There was a significant increase in the weight index of the epididymis in the carob 3 group in comparison to the sham group (p = 0.01). The number of positive tunnel cells was not statistically significant between different groups (p>0.05). The level of malondialdehyde decreased in the carob 1 and carob 3 groups, but this reduction was not statistically significant (p > 0.05). In addition, the statistical analysis showed a significant difference in the mean superoxide dismutase levels in the carob 2 and carob 3 groups in comparison to the sham group (p ≤ 0.001). The statistical analysis showed a significant increase in the mean level of the catalase enzyme in the carob 1 group in comparison to the sham (p = 0.02), and carob 2 groups (p = 0.008). Conclusion: The administration of 200 mg of the carob fruit extract for 14 days increased the testicular index as well as sperm parameters and decreased the level of oxidative stress in the testicular tissue of adult mice.
