Introduction: The reading process involves several cognitive skills, such as metalinguistic skills and memory. These processes lead the student to understand the ideas of a text for the creation of mental models, based on the context and your point of view. Objective: To analyze the performance of metalinguistic and reading skills in students with dyslexia, learning difficulties, and learning disorders. Methods: This is an observational and cross-sectional study. The group comprised 80 students from the 3rd to the 5th year of elementary, both gender, aged between eight and ten years and 11 months. The sample, distributed in four groups as follows: Group I composed of 20 students with an interdisciplinary diagnosis of dyslexia, Group II make up of 20 students with a multidisciplinary diagnosis of learning disorders, Group III by 20 students with learning difficulties and Group IV comprised 20 students with excellent academic performance. Every student, individually, underwent the application of the Metalinguistic and Reading Skills Tests Protocol. Results: The Groups I and II had more errors than Group III and IV. Group III showed a higher number of mistakes than Group IV. Scores were obtained from the metalinguistic tests, word reading and pseudowords, and repetition of no -monosyllable and polysyllable words. Conclusion: Students with dyslexia and learning disorders had a higher number of mistakes in syllabic and phonemic tests, reading words, and pseudowords than students with learning difficulties and excellent academic performance.

Abstract Objective: To determine the relationship of severity of thrombocytopenia with various grades of esophageal varices in patients with cirrhosis. Study design: A cross sectional observational study. Place and duration of study:  Medicine department of Pakistan Railway General Hospital from 1st September, 2018 to 31st August, 2020. Material and Methods: The record of 100 patients with cirrhosis having concomitant thrombocytopenia and esophageal varices was retrospectively analyzed.  The information about clinical, hematological, biochemical, ultrasound and endoscopic findings was retrieved from medical record. On the basis of platelet count, four groups were made. Group I consisted of patients with a platelet count ≤ 20,000/ µl, group II 21,000-49,000/ µl, group III 50,000-99,000/ µl, and group IV 100,000- 149,000/ µl. Esophageal varices were reclassified as small and large varices group depending on the size. Correlation of thrombocytopenia with grading of esophageal varices was calculated using spearman’s correlation. Results:   Out of 100 patients, 76% had large varices and 24% had small varices. Thrombocytopenia was more severe in patients with large varices group when compared with small varices group. There was significant negative correlation between thrombocytopenia and grading of esophageal varices (r= -.691; P < 0.001). Conclusion: The severity of thrombocytopenia increased with increase in the size of esophageal varices.  Low platelet count can strongly predict large varices in patients with cirrhosis.

BACKGROUND: The increased strength of zirconia has resulted in its widespread application in clinical dentistry. Nevertheless, the fracture of veneering porcelains remains one of the key reasons of failure. OBJECTIVE: The objective of this study was to compare and analyze the influence of surface conditioning methods on the core-veneer bond strength of zirconia restorations. METHODS: Thirty specimens of zirconia core with sizes 10 × 5 × 5 mm were layered with porcelain of sizes 5 × 3 × 3 mm. On the basis of different surface conditioning methods, four groups were made: Group I: abrasion with airborne alumina particles of 110 μm size, Group II: sandblasting with silica coated alumina particles of 50 μm in size, Group III (modified group): alteration with a coating of zirconia powder prior to sintering, and Group IV (control group): metal core specimens. The shear force of all specimens was tested using a universal testing machine with a 0.5 mm/min crosshead speed. One-way analysis of variance (ANOVA) and Tukey’s post hoc pair wise comparison (p= 0.05) were performed to analyze the shear bond strength. A scanning electron microscope was used to assess the fractured specimens. RESULTS: A statistically significant difference was noted between the groups. The mean value of shear bond strength was 40.25 MPa for Group I, 41.93 MPa for Group II, 48.08 MPa for Group III and 47.01 MPa for Group IV. CONCLUSIONS: The modified zirconia group and control group demonstrated a significantly higher mean bond strength than that of Group I, where airborne particle abrasion was used. The scanning electron microscope showed that cohesive fracture in the porcelain veneers was the main problem of failure in altered zirconia. The modified zirconia specimens in Group III demonstrated significantly improved values of shear bond strength.

AbstractRecent years have seen a rising incidence of male infertility, mostly caused by the decline of sperm quality. The ratio of infertile males to infertile females has escalated from 3:7 in 2013 to current 5:5, which turns male infertility into the research focus of reproductive medicine. This study aimed to clarify the effect of reproductive tract infection by ureaplasma urealyticum (UU) and chlamydia trachomatis (CT) on the DNA integrity and routine semen parameters of infertile males. A retrospective study was performed. A total of 259 infertile males who were treated at the Andrological Laboratory Examination and Reproductive Medicine Center in our hospital were analyzed. qRT-PCR was used to examine the infection status of CT and UU. According to the eligibility criteria, we evaluated the semen parameters and biochemical data of 253 men. Based on the results of PCR, the subjects were divided into four groups: Group I (CT positive, 63 cases), Group II (UU positive, 60 cases), Group III (CT positive and UU positive, 62 cases), and Group IV (no infection, 68 cases). DNA fragmentation index (DFI), sperm count, vitality and morphology, elastase level, seminal plasma malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed. Compared to Group IV, three groups (Group I, Group II and Group III) showed difference in semen volume, proportion of sperm with normal morphology, sperm motility, progressive motility, and vitality (P < 0.05). Compared to Group IV, Group II and Group III showed difference in DFI (P < 0.05). Compared to Group IV, Group II and Group III showed difference in elastase level (P < 0.05). VCL, VSL, VAP, WOB, ROS, TM, HDS showed differences between groups of abnormal/normal WBC (*P < 0.01).UU infection significantly increased the level of seminal leukocytes only in Group II, but not in the other three groups, indicating that UU is a factor to increase the level of seminal leukocytes. Compared with the normal leukocyte group, there were significant differences in total motility, forward motility and normal sperm ratio between the two groups. The proportion of sperm with abnormal morphology (mostly in the head) showed obvious difference between groups of high and normal seminal leukocytic levels. At the same time, in this study, SCGE and SCD verified that leukocytes could damage sperm DNA by increasing ROS, which ultimately affects male fertility.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

We evaluated the dose-response relationship between the plasma amino acid (AA) concentration and renal hemodynamics in eight normal subjects. After an overnight fast, a balanced 10% AA solution was infused for 180 min at five separate infusion rates: 0.5 (group I), 1.0 (group II), 2.0 (group III), 4.0 (group IV), and 6.0 (group V) ml.kg-1.min-1 on separate days. Basal plasma AA concentration was 1.87 +/- 0.1 mmol/l and increased to 2.26 +/- 0.1 (group I), 2.66 +/- 0.2 (group II), 3.79 +/- 0.5 (group III), 5.81 +/- 0.4 (group IV), and 7.41 +/- 0.4 mmol/l (group V). Basal glomerular filtration rate (GFR) and renal plasma flow (RPF) averaged 95 +/- 4 and 476 +/- 29 ml.1.73 m-2.min-1, respectively, and rose to 98 +/- 5 and 506 +/- 40 (group I) [P = not significant (NS)], 102 +/- 3 and 533 +/- 30 (group II) (P < 0.05 vs. basal), 110 +/- 4 and 567 +/- 29 (group III), 115 +/- 7 and 610 +/- 55 (group IV), and 117 +/- 7 and 614 +/- 66 ml.1.73 m-2.min-1 (group V) (P = NS vs. group IV). Basal plasma glucagon concentration averaged 68 +/- 10 pg/ml and increased to 74 +/- 10 (group I), 83 +/- 11 (group II) (P < 0.05 vs. basal), 100 +/- 14 (group III), 121 +/- 14 (group IV), and 229 +/- 35 pg/ml (group V) (P < 0.01 vs. basal). Increases in plasma growth hormone (GH) and insulin levels were observed only during groups IV and V.(ABSTRACT TRUNCATED AT 250 WORDS)

Tonometry is a minimally invasive method for estimating gastrointestinal intramural pH (pHi). Tissue pH is calculated by using the Henderson-Hasselbalch equation and measurements of arterial [HCO-3] and CO2 tension (PCO3) of saline contained in a Silastic balloon within the lumen of the gut. The validity of the method rests on two key assumptions: 1) PCO2 in saline in the tonometer balloon is similar to tissue PCO2 and 2) tissue and arterial [HCO-3] are similar. To validate this method, ileal pHi measured directly with a microelectrode was compared with pHi estimated tonometrically in four groups of anesthetized pigs. Group I (n = 4) were controls. In group II (n = 4), intestinal tissue acidosis was induced by total occlusion of the superior mesenteric artery (SMA). In group III (n = 5), acidosis was induced by partial occlusion of the SMA. In group IV (n = 4), tissue acidosis was induced by endotoxemia. Agreement was excellent between direct and tonometric measurements in groups I and IV and less good in groups II and III. Weighted mean correlation coefficients (rw) for the two measurement methods were 0.743 and 0.9447 in groups II and IV, respectively. Correlation coefficients for the individual animals in group III were more variable than the other groups and ranged from 0.547 to 0.990. The tonometric method for measuring GI pHi is invalid under conditions of zero flow and leads to error under conditions of low flow. However, the method is reliable in the setting of tissue acidosis induced by endotoxemia.

The effect of concurrent exposure of toxic concentrations of lead and endosulfan were evaluated on oxidative stress parameters in male wistar rats. Group I served as untreated control whereas Group II received drinking water containing lead as lead acetate @1000 ppm (Pb1000). Group III was exposed to feed containing technical grade endosulfan @ 100 ppm (E100). Group IV was exposed to Pb (1000) +E (100). All the treatments were given daily for 28 days. Combination of lead and endosulfan modified the indices of oxidative stress in the parameters such as lipid peroxidation, reduced glutathione, superoxide dismutase and catalase in rats as compared to their individual compounds. The results suggest that the combination of these individual compounds may have the potential to modify oxidative stress produced by single compounds in male rats

Introduction: Anaemia is a pathologic deficiency in oxygen-carrying haemoglobin in red blood cells which may be the result of genetic diseases, infections and deficiency of several nutrients. Nepal is one of the developing countries where anaemia is one of the most serious public health problems. So, a study was planned to evaluate the prevalence of anaemia among children under five years in tertiary care hospital of Nepal. Methods: A cross-sectional study was carried out from August 2011 to January 2012 using a structured questionnaire interview and observation. The children were divided into three groups: group I (0-1 years), group II (>1-3 years), group III (>3-5 years). Anaemia was assessed using  haemoglobin measurement in gram in decilitre on Sysmex KX -21 (automated haematology analyzer). The severity of anaemia were grouped as follows: severe anaemia, < 7.0 g/dL; moderate anaemia, 7.0 to 8.9 g/dL; and mild anaemia, 9.0 to 10.9 g/dL as per WHO classification. Stool test was also carried out to assess worm infestation. Data were analysed using SPSS 11.5. Results: There were 208 children among which 52.9 % were male while 47.10 % were female.  The overall prevalence of anaemia was found to be 49.5% of which 43.3% had mild, 15.8% had moderate and 0.5% had severe anaemia. Out of 20 children in group I, 70 % were anaemic. Among the 94 each in group II and group III, children suffering from anaemia were 51% and 43% respectively. The stool investigations showed that 5.3 % children suffered from worm infestations.   Conclusions: prevalence of anaemia was seen in 49.5% of children below five years age group and the diet and worm infestations didn’t affect it.doi:  http://dx.doi.org/10.3126/mjsbh.v13i1.12998
