The aim of the paper was to find out the level of changes in the sperm quality in two groups of boars in the insemination (A and B) with diametrically different contents of morphologically abnormal spermatozoa (AS) with an interval of 25 weeks between semen collection I and collection II. In the group A there were 22 boars with the AS content up to 10%, in the group B 16 of boars with the AS content above 40% in collection I. Both groups were comparable concerning the parameters of the performance test results and in quantitative parameters of the semen from collection I. They differed significantly in the AS content (P < 0.01) and in the age (P < 0.05). In collection II in both groups the semen volume increased significantly (A – P < 0.01; B – P < 0.05), in the group A the number of spermatozoa per ejaculate and per day also increased (P < 0.01). In the group B there was an insignificant clear decrease in the sperm concentration (P > 0.05). In comparison with the group B the group A can be characterized as a group with significantly higher dynamics in the sperm production per ejaculate. An opposite trend was noted in the total AS content. In the group A there was a significant increase (P < 0.001) and in the group B a significant decrease (P < 0.001) in collection II. In the group A there was a deterioration of the AS content in 7 boars (31.8%), in the group B an improvement in 7 boars (43.7%). Particular monitored AS forms are given. A significant difference in the total AS content between both groups was in favour of the group A (P< 0.001). While no boars from the group A exceeded the limit in the AS content for the applicability of semen for insemination (in theCzech   Republic25%), in the group B they remained above this limit without applicability possibility. The detected variations and prevailing stability in the AS occurrence in boars kept in the same conditions lead us to a consideration of hereditary characteristics of the spermatogenesis factor, of considerable persistence of the level of monitored characteristics and to a consideration of applicability of the phenotype AS presentation to selection of boars for artificial insemination.

The objective of this study was to investigate the effect of using different extenders <italic>viz.</italic> Androhep, Safecell Plus and SUS during cryopreservation on quality of frozen-thawed boar semen. Semen volume, sperm motility, sperm concentration, percentage of morphologically abnormal spermatozoa, total number of spermatozoa per ejaculate and activity of the enzyme aspartate aminotransferase (AST) were assessed in fresh semen collected from 39 fertile AI boars. Semen from each boar was divided into three portions and diluted 1:1.5 in extender Androhep, Safecell Plus and SUS and keep at 17°C for 15-h holding time before cryopreservation. Then sperm was cryopreserved. Straws were thawed in a water bath at 38°C for 40s and post-thaw sperm motility with AST activity was assessed. Significant difference in post-thaw sperm motility was found between extender Androhep and Safecell Plus (P<0.05). AST activity did not differ significantly between tested extenders (P>0.05). In conclusion, the results of the study indicate that using Safecell Plus extender during holding period before cryopreservation significantly affected post-thaw sperm motility.

Objective: To compare clinical efficacy of diacerein-ginger with diacerein alone in treating knee osteoarthritis. Duration and place of study: It was a randomized clinical trial conducted from 21st September 2018 to 31stMarch 2019, in medical OPD of a private hospital in Karachi. Methodology: 60 diagnosed patients of knee osteoarthritis were included in this study. Male and female patients 50 years of age, fulfilling the inclusion criteria and after written informed consent experienced a wash-out period of 72 hours. These patients were systematically randomized into 2 groups each having 30 members. Group A received capsule Diacerein 50mg + capsule Ginger 550 mg twice daily and group B received capsule Diacerein 50mg twice daily, for 12 weeks. Parameters checked at 0, 6 and 12 weeks were: Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index, pain at rest and movement (Visual Analogue Scale). Comparison of the two groups was done by independent t-test. Results: Among 60 patients; 20 (33.33 %) were males and 40 (66.66%) were females. 4 patients in group A and 4 in B, dropped out during the study. Comparison of group A with group B in WOMAC and pain (at rest and movement) scores showed insignificant difference at day 0 before prescription of the drugs. However comparison showed highly significant difference (P-value < 0.001) between the two groups in WOMAC, pain at rest and movement scores at the end of 6th and 12th weeks of intervention. Conclusion: Diacerein-Ginger is clinically more efficacious for management of knee OA than Diacerein alone

Objectives When there is a difference in hearing on both ears, where to perform the first cochlear implantation (CI) becomes an important issue. The purpose of the study was to evaluate which ear should be chosen for the first implantation in sequential bilateral CI with a long inter-implant period. Methods The study population consisted of 34 severe-to-profound sensorineural hearing loss pediatrics with the inter-implant period of ≥3 years between the first CI (CI-1) and the second CI (CI-2) before the age of 19 (mean of inter-implant period: 7.1-year). The patients were classified into Group A (CI-1 was performed on the ear with better hearing), Group B (CI-1 on the ear with worse hearing), or Group C (symmetrical hearing in both ears). Speech intelligibility test results were compared between the groups. Results The monosyllabic word scores of CI-1 were excellent in Groups A (91.7±7.9%) and B (92.5±3.6%) but slightly lower in Group C (85.7±14.9%) before the second implantation ( P = .487). At 3 years after the second implantation, all groups demonstrated excellent scores in the bilateral CI condition (95.9±3.0% in Group A; 99.1±.8% in Group B; 97.5±2.9% in Group C, P = .600). However, when the patients were tested in using CI-2 only in Groups A and B after using bilateral CI for 3 years, the scores were inconsistent in Group A (79.6±23.9%; range: 22.2-94.4%), while those were higher and more constant in Group B (92.9±4.8%; 86.8-100.0%). Conclusions The first CI is strongly recommended to perform on a worse hearing ear if they had different hearing levels between ears. Even with the first CI on a worse hearing ear, its performance never deteriorates. In addition, if they receive the second CI several years later, it will be likely that the second one functions better.

Background: Present research studied the surface hardness and roughness dependence on polymerization. Polymerization of composites occurs through chain reaction that is induced by free radicals. Oxygen in the air decreases the excitability of the photo initiator, causing polymerization interference. Oxygen inhibition layer (OIL) is formed on the surface. OIL can be reduced by curing the composite through by application of glycerin to the surface. Purpose: To determine the effect of glycerin on the surface hardness and roughness of nanofill composite. Material and Methods: 64 specimens of composite (Z350 XT, 3M) were prepared using a disc-shaped acrylic. The groups were divided into group A surface hardness (N=32) and group B surface roughness (N=32). Group A1, the specimen was coated with glycerin and light cured for 20 s and group A2, the specimen was exposed to air and light cured for 20 s. Group B1 was coated with glycerin and light cured for 20 s and Group B2 was exposed to air and light cured for 20 s. The specimens were stored in distilled water for 24 h at 370. Measuring with Vickers and surface roughness tester and. Data were statistically analyzed using Mean-whitney U Test. Results: There were statiscally significant difference between the surface hardness and roughness of nanofill composite coated with glycerin and without glycerin (p<0,05) Conclusion: The surface hardness of nanofill composite resin coated with glycerin is higher than composite without glycerin and the surface roughness of nanofill composite resin coated with glycerin is lower than composite without glycerin

The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars. Ejaculates were collected as sperm-rich fractions (SRF) and bulk samples (BE) using a gloved-hand technique. Fresh semen quality in terms of semen volume, sperm concentration, total sperm motility and pH were conventionally evaluated. Then, semen was cryopreserved using the liquid nitrogen vapour method. The post-thaw sperm quality was evaluated by assessing sperm motility, live sperm with normal apical ridge and high mitochondrial energy status, lipid peroxidation was evaluated using CASA and fluorescent multiple staining and MDA levels were determined using a spectrophotometer, respectively. In terms of fresh semen quality, sperm motility in fresh semen did not differ significantly between the two groups. The treatment with the greater mean volume (BE; P &lt; 0.05) had a lower mean sperm concentration (P &lt; 0.05); meanwhile, the mean ejaculate pH collected as BE was more basic compared with SRF (P &lt; 0.05). However, there were no significant post-thaw quality changes between sperm-rich fractions and bulk samples of semen. In conclusion, ejaculates can be collected as bulk samples without the need to classify fractions for boar semen cryopreservation.

Introduction: Dentin hypersensitivity (DH) is the most common concern faced by most dentists in their day-to-day clinical practice. It is characterized by short-term, acute pain of variable intensity, which occurs in response to thermal, tactile, osmotic or chemical stimuli that cannot be attributed to any other type of defect or dental decay. Casein phosphopeptide varnish is a newer material used to treat dentinal hypersensitivity as it reduces demineralization and promotes remineralization. The aim of this study is to evaluate the efficacy of casein phosphopeptide based varnish (MI Varnish®) vs sodium fluoride-based varnish (Fluoritop SR® varnish) in treating dentinal hypersensitivity. Materials and methods: 40 subjects with a chief complaint of DH were divided into two equal groups, Group A (MI varnish®) and Group B (Fluoritop SR® varnish). Scaling and root planing was done and sensitivity was assessed using Visual analog scale (VAS) at baseline. On the 14th day, sensitivity was reassessed using VAS. The data obtained were subjected to statistical analysis using students‘t’ test. Results: On intragroup comparison, VAS scale showed a statistically significant difference for both the groups. On intergroup comparison, no statistical difference was found between both groups. (p = 0.139) Conclusions: From the above results, it can be concluded that MI varnish® and Fluoritop SR® varnish are equally efficacious in reducing dentinal hypersensitivity.

Abstract Objective: To evaluate the effect of acephalic spermatozoa syndrome on sperm quality in semen with different proportions of headless sperm.Design: Case control study.Setting: Andrology Laboratory.Patient(s): A total of 391 patients with headless sperm and 400 prenatal examination patients with no headless sperm who underwent semen analysis at the andrology laboratory.Intervention(s): None.Main Outcome Measure(s): The correlation of the proportion of headless sperm in semen with semen parameters.Result(s): All semen parameters except the semen volume were negatively (P<0.05) correlated with the proportion of headless sperm in the semen. The semen samples were divided into three groups based on the proportion of headless sperm (PHS) as follows: 0<PHS≤10% (n=249, group A), 10<PHS≤20% (n=71, group B) and PHS>20% (n=71, group C). Nearly all semen parameters were significantly lower in group B and group C than in the control group (P<0.05). However, in group A, only the vitality and motility parameters were lower than those of the control group.Conclusion(s): Semen samples containing headless sperm tend to have lower semen parameters than samples without headless sperm. Increases in the proportion of headless sperm in semen samples are associated with decreases in semen quality.

Abstract Background The role of sexually transmitted infections (STIs) in semen parameters and male infertility is still a controversial area. Previous studies have found bacterial infection in a minority of infertile leukocytospermic males. This study aims to investigate the prevalence of STIs in semen from subfertile men with leukocytospermia (LCS) and without leukocytospermia (non-LCS) and their associations with sperm quality. Methods Semen samples were collected from 195 men who asked for a fertility evaluation. Infection with the above 6 pathogens was assessed in each sample. Sperm quality was compared in subfertile men with and without LCS. Results The LCS group had significantly decreased semen volume, sperm concentration, progressive motility, total motility and normal morphology. The infection rates of Ureaplasma urealyticum (Uuu), Ureaplasma parvum (Uup), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), herpes simplex virus-2 (HSV-2) and Neisseria gonorrhoeae (NG) were 8.7 %, 21.0 %, 8.2 %, 2.1 %, 3.6 %, 1.0 and 0 %, respectively. The STI detection rates of patients with LCS were higher than those of the non-LCS group (52.3 % vs. 39.3 %), although there was no statistically significant difference between the two groups (P = 0.07). All semen parameters were not significantly different between LCS with STIs and without STIs, except the semen volume in the MG-infected patients with LCS was significantly lower than that in the noninfected group. Conclusions LCS was associated with a reduction in semen quality, but was not associated with STIs.
