ABSTRACT Objective: This study aimed at evaluating whether changes in the insertion angle is a determining factor in the positioning of the miniscrews body in a region with larger interradicular space in the posterior maxilla. Methods: Analysis of 60 posterior maxillary quadrants were made using images obtained by means of cone-beam computed tomographic image (CBCT), with 0.076-mm voxel, which presented a real miniscrew inserted in the mesial region of the maxillary first molars, serving as reference point for the placement of the virtual miniscrews. Measurements of the distances between roots were made in three points on the body of the virtual miniscrews (A, B and C), at four different angulations, 70o, 60o, 50o and 40o (T1 to T4), in relation to the long axis of the second premolar. This evaluation was made in four groups, selected in accordance with the disposition of the roots of the second premolars and first molars: Group 1 (all types of roots), Group 2 (convergent roots), Group 3 (divergent roots) and Group 4 (parallel roots). Results: There were no statistically significant differences in the measurements of points A, B and C, at the different angles (70o, 60o, 50o and 40o) and in the different groups (p > 0.05). Conclusions: Changes in the insertion angle is not a determinant factor in the positioning of miniscrews body in regions with larger interradicular space in posterior maxilla.

This study was conducted to find out hepatoprotective activity of hesperidin (HES) 100mg/kg body weight (b.w.) against ciprofloxacin (CPX) 100 mg/kg induced hepatotoxicity in local breed rabbits .CPX is a broad spectrum antibiotic used for treatment of many bacterial infections. Twenty four male rabbits were divided into four groups ,group1: control, (1 ml/kg Saline orally) group 2: CPX (100 mg/kg orally) for (14) consecutive days , group 3: HES (100 mg//kg) orally for (14) consecutive days group 4: CPX (100 mg/kg orally) plus HES (100 mg//kg orally ) for (14) consecutive days. All the rabbits were killed on the (15) day of the experiment, and then the blood, and livers samples were taken. CPX induced hepatotoxicity was proved by a significant (p less than 0.01) reduction in the body weight ,and a significant (p less than 0.01) increased serum aspartate transaminase (AST), alanine transaminase (ALT) , Malonaldehyde enzyme (MAD) and histopathological changes. Protective hepatic toxicity effect and oxidative damage caused by CPX significantly (p less than 0.01) increasing in body weight and significantly (p less than 0.01) decreasing AST , ALT, MAD and improving tissue morphology in HES (100 mg//kg) . These results assure that HES (100 mg//kg) antioxidant effects can protect CPX-induced hepatotoxicity in rabbits.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

<b>Background:</b> Acute appendicitis is the most common cause of acute abdomen. Delay in diagnosis increases the mortality and morbidity. <br><b>Aim: </b>In this study, we aimed to investigate whether the body mass index is useful in diagnosis and whether the neutrophil /lymphocyte and platelet/lymphocyte ratios can help in determining the inflammation level of acute appendicitis. <br><b>Meterial and Methods:</b> Cases of appendectomy performed between June 2012 and December 2018 in our clinic were analyzed retrospectively. Based on the pathology results of the cases included in the study, 4 groups were formed, i.e.: Group 1 (initial stage), Group 2 (catarrhal stage), Group 3 (phlegmonous-gangrenous stage) and Group 4 (perforation). The study compared age, body mass index, leukocyte values, red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), platelet /lymphocyte ratio (PLR), and mean platelet volume (MPV) between groups. <br><b> Results:</b> 828 cases were included in the study. When compared between groups, the values of Group 3 and Group 4 were higher than those of Group 1 and Group 2 for PLR and NLR. There was no difference in RDW and MPV values in the blood. When Body Mass Index (BMI) was compared between groups, it was found to be significantly higher with increasing histopathological stage. <br><b>Conclusion:</b> In acute appendicitis, the blood leukocyte value, elevated PLR and NLR are helpful in diagnosis. We aimed to emphasize that the diagnosis of acute appendicitis is delayed in patients with a BMI above 30 and/or at age of over 40 years, with the perforation rate being determined more frequently.

This study aimed to reveal relationship between the extensiveness of trichophytosis on the body and serum zinc levels in cattle. This study was carried out on 92 cattle with trichophytosis and 50 healthy ones. Serum zinc levels of healthy cattle were evaluated as control. The cattle with trichophytosis separated into 5 groups according to diffusiveness of the diseases. Experimental groups of this study were designed as follows; Group 1: up to 1 cm, Group 2: 1-5 cm, Group 3: 5-10 cm, Group 4: 10-20 cm and Group 5: widespread on the body. Serum zinc levels measured by atomic absorption spectrophotometer equipped with flame system. In general, the mean level of Zn in trichophytosis groups (0.613±0.013 mg Zn/L) was statistically lower than healthy ones (0.900±0.017 mg Zn/L). A negative correlation was determined between the diffusiveness degree of trichophytosis and serum zinc levels (r = -0.772). Serum Zinc levels were statistically decreased from the control group to group 3. However, a stable course was observed from 3 to 5. Therefore, the value of group 3 (0.6 mgZn/L) was determined as a critical value for the cattle with trichophytosis. According to regression analysis results, it was observed that the extensiveness of the trichophytosis lesions affected the levels of serum Zn levels significantly (r2=59.6%). Consequently, serum zinc levels of cattle decreased in an inversely proportional manner to the diffusiveness degree of trichophytosis and stabilization was observed at the level of 0.6 mg Zn/L.

Abstract Study question Does the body mass index (BMI) have an impact on semen analysis results? Summary answer The increase in BMI has a negative impact on sperm motility. What is known already Obesity is an increasingly prevalent health condition worldwide and can affect male fertility in various ways. It is known that obesity can cause testicular inflammation, higher testicular temperature, hypogonadism, sperm DNA fragmentation, and erectile dysfunction. However, there are still conflicting data regarding the correlation between BMI and semen parameters in the seminal analysis. Study design, size, duration Observational, cross-sectional, retrospective study using data from 1147 patients seen at a private infertility clinic between 2010 and 2020. The data were collected from electronic records in a prospective database. Participants/materials, setting, methods Patients were divided according to BMI (healthy weight, overweight, obesity classes I, II, III), and their seminal profiles were compared, according to 2010’s World Health Organization’s parameters. Cancer, cryptorchidism, viral orchitis, altered karyotype, Y chromosome microdeletions, vasectomy reversion, and testosterone use were excluding factors. Student t-tests and multiple linear regression were used for statistical analysis. The results were adjusted for age, alcohol, tobacco, and drug use, medication intake, physical activity, comorbidities, and scrotum heat factors. Main results and the role of chance From a total of 1384 patients, 219 were excluded. The BMI varied between 18,9 and 50,8 kg/m². From the 1147 patients, 297 had BMI 18.5–24.9 kg/m² (healthy weight, group 1), 611 had BMI 25–29.9 kg/m² (overweight, group 2), 179 had BMI 30–34.5 kg/m² (obese, group 3), 60 had BMI ≥ 35 kg/m² (extremely obese, group 4). The mean age for groups 1 through 4 was 37.6, 38.5, 38.2, and 36.5 years old. The comparison of the groups’ seminal parameters shows a significant decrease in progressive and total motility in patients with BMI ≥ 35 kg/m².The progressive motility was 43.8% in group 1, 44.1% in group 2, 42.4% in group 3, and 35.2% in group 4 (p = 0.07) and the total motility was 54.4%, 54.1%, 53.6%, and 45.9%, respectively (p = 0.012). The complementary analysis determined BMI 29 kg/m² as the cutoff for negative impact on progressive motility (p = 0.044) and 31 kg/m² on total motility (p = 0.036). The results were still significant after age, use of cannabis, and hypertension adjustments – the other possible interfering factors were not significant. Limitations, reasons for caution Besides the fact that this was a retrospective study, it also has a smaller sample size of patients with extreme obesity. This is probably related to the fact that the patients seeking reproductive treatment in a private clinic have a greater purchasing power and lower prevalence of obesity. Wider implications of the findings: In this study, sperm quality is negatively affected by BMI, with impairment since 29 kg/m² for progressive and 31 kg/m² for total motility. Our data support the potential deleterious role of obesity on semen parameters, reinforcing the importance of weight control in infertility prevention. Trial registration number Not applicable

Objectives: To evaluate the effects of adding dried guava waste and dried olive cake as substitution of alfalfa in diet on rabbit farm profits. Design: Randomized controlled experimental study. Animals: Thirty-six Hypluse white rabbits at the age of 33 days with an average body weight of 696.6 g. Procedures: Rabbits were allocated into four groups of nine animals each. Group 1 (Control group) was fed on a basal rabbit diet. Group 2 was fed on a diet containing 5% dried guava waste (DGW) as a substitute for alfalfa, Group 3 which was fed on a diet containing 5% dried olive cake (DOC) as a substitute for alfalfa, and Group 4 which received a diet containing combination of both 5% DGW and 5% DOC as a substitute for alfalfa. Results: The addition of 5% DGW and 5% DOC in diets of rabbits as a substitute for alfalfa resulted in improvements in body weights of animals when compared to the basal diets, whereas the inclusion of the two materials in the diet of rabbits lowered the body weights of animals. The feed intake in group (two and three) was lower than that of the control group. Groups (two and three) showed lower values of feed costs, total variable costs and higher total return, and thus had higher values of profits when compared to the control group. Group four showed higher total variable costs and total costs, while the total return was the lowest and consequently the profit was the lowest also. Conclusion and clinical relevance: The addition of either 5% DGW or DOC in diets of rabbits to substitute a portion of alfalfa appeared satisfactory for rabbit farm profit as their profit were higher than control group by 5.37 and 11.74 LE respectively, while their combination did not appear to be useful and therefore was not recommended.

Mercury toxicity leads to cell damage in many organs of the body. The authors comparatively examined the ability of different food additives with medicinal properties to protect against mercury (Hg) accumulation in the liver following different treatment interventions and modes of administration. Rats were fed on either 7% w/w Zingiber officinale, 7% w/w Garlic, 10% w/w Lycopersicon esculentum, or 5%, w/w Garcinia kola (all in rat chow), while Hg (10 ppm) was given in drinking water. The additives were administered together with the metals (group 2), a week after (group 3) or a week before metal exposure (group 4) for a period of six weeks. The metal accumulations in the liver were determined using an Atomic Absorption Spectrophotometer (AAS). All the additives significantly (p<0.05) reduced the accumulation of mercury in the liver, percentage protection being lowest for ginger as an additive and highest for garlic. Percentage protection was significantly higher at weeks 4 (P<0.01) and 6 (P<0.001), compared to week 2. The mode of administration did not interact significantly with either time or additive in their relationship to percentage protection. Each additive provided significant protection from mercury and protection generally varied with time, but variations were not modified by mode of administration.

Menopause was a condition of the body when ovaries stopped producing ovum; ovum is the main producer of estrogen hormone. Menopause can increasing lipid profile in blood; it causes any problems in the cardiovascular system. People of North Sumatra have long used Bangun-Bangun leaves as a breastfeeding agent; it contains flavonoid bioactive compounds, which are be expected to replace lost estrogen hormone. This study determined the estrogenic activity of Bangun-Bangun leaves ethanol extract (BBLEE) on lipid levels of ovariectomized female rats as a menopausal model. BBLEE has obtained by maceration techniques with 96% ethanol and extract used on 24 ovariectomized rats which were divided into 6 groups. Group 1 (normal), group 2 (positive) was treated by estradiol at dose of 0.18 mg/kg BW, group 3 (negative) was treated by 0.5% Na-CMC and group 4, 5, 6 were treated by BBLEE at dose of 30, 60, 90 mg/kg BW given orally for 14 days. The data were analyzed by ANOVA and Post Hoc Tukey HSD test. The result showed that effective dose of BBLEE was 90 mg/kg BW which improved lipid profile (TC = 55.75±0.47; TG = 63.00±0.40; HDL = 37.00±0.81; LDL = 30.50±0.86) in blood of ovariectomized female rats as a menopausal model. BBLEE at the dose of 90 mg/kg BW can ameliorate the lipid profile in the blood of ovariectomized female rats as a menopausal model.

During follicular development in the mammalian ovary, several functional changes occur in the granulosa cells in response to steroid hormones and gonadotropins (1,2). In particular, marked changes in the content of membrane-associated receptors for the gonadotropins have been observed (1).We report here scanning electron microscope observations of morphological changes that occur on the granulosa cell surface in response to the administration of estradiol, human follicle stimulating hormone (hFSH), and human chorionic gonadotropin (hCG).Immature female rats that were hypophysectcmized on day 24 of age were treated in the following manner. Group 1: control groups were injected once a day with 0.1 ml phosphate buffered saline (PBS) for 3 days; group 2: estradiol (1.5 mg/0.2 ml propylene glycol) once a day for 3 days; group 3: estradiol for 3 days followed by 2 days of hFSH (1 μg/0.1 ml) twice daily, group 4: same as in group 3; group 5: same as in group 3 with a final injection of hCG (5 IU/0.1 ml) on the fifth day.
