The seasonal distribution of marine viruses and their relationship with heterotrophic bacteria in the coastal and offshore area of the central and southern Adriatic were studied. Additionally, the percentage of high (HNA) and low (LNA) nucleic acid bacteria between the total number of bacteria and the distribution of heterotrophic nanoflagellates (HNF) as a major predator of bacteria were studied as well. The viral abundance ranged from 3.55 to 27.32 × 106 virus-like particles mL-1, and was on average 25-fold higher than bacterial abundances at all investigated stations. The highest viral abundances were found at coastal stations, especially in the area influenced by the rivers Krka and Jadro, whereas the lowest values were found in the open sea and in the coastal area of the southern Adriatic. No significant difference in relationship of viruses with HNA and LNA bacterial groups were established. The ratio between viruses and bacteria (VBR) was higher during the colder part of the year, which coincided with lower HNF abundance and vice versa during the warmer part of the year. This suggests that HNF grazing could be more important in controlling bacterial abundance during the warmer part of the year, and viral lysis during the colder part of the year.

Southern Adriatic (Eastern Mediterranean Sea) is a region strongly dominated by large-scale oceanographic processes and local open-ocean dense water formation. In this study, picoplankton biomass, distribution, and activity were examined during two oceanographic cruises and analyzed in relation to environmental parameters and hydrographic conditions comparing pre and post-winter phases (December 2015, April 2016). Picoplankton density with the domination of autotrophic biomasses was higher in the pre-winter phase when significant amounts of picoaoutotrophs were also found in the meso-and bathy-pelagic layers, while Synechococcus dominated the picoautotrophic group. Higher values of bacterial production and domination of High Nucleic Acid content bacteria (HNA bacteria) were found in deep waters, especially during the post-winter phase, suggesting that bacteria can have an active role in the deep-sea environment. Aerobic anoxygenic phototrophic bacteria accounted for a small proportion of total heterotrophic bacteria but contributed up to 4% of bacterial carbon content. Changes in the picoplankton community were mainly driven by nutrient availability, heterotrophic nanoflagellates abundance, and water mass movements and mixing. Our results suggest that autotrophic and heterotrophic members of the picoplankton community are an important carbon source in the food web in the deep-sea, as well as in the epipelagic layer. Besides, viral lysis may affect the activity of the picoplankton community and enrich the water column with dissolved organic carbon.

To investigate the relationship of MUC1, MUC5AC, and the syndrome of spleen and stomach, 109 subjects (34 peptic ulcer (PU), 62 chronic gastritis (CG), and 13 healthy volunteers (CON)) were included. All the subjects included were surveyed with questionnaire to classify them into damp-heat syndrome of spleen and stomach (DHSS), spleen-qi deficiency syndrome (SQD), and CON, examined by gastric endoscope, and biopsied. Rapid urease and methylene blue staining (MBS) were performed on every subject to diagnose for Helicobacter pylori (Hp) infection, and both were defined as Hp-positive. Hematoxylin and eosin (HE) staining was performed on every specimen to explore the histomorphology, inflammatory degree, and inflammatory activity of different groups; then Elivision™ plus kit was used to test the expression of MUC1 and MUC5AC. All the results of digital images were reviewed by two experts blindly. The inflammatory degree with Hp infection was higher than those uninfected or CON, but no significant difference was found between DHSS and SQD. And the expressions of MUC5AC with positive Hp was higher than those with negative Hp or CON regardless of the deficiency and solid syndrome of spleen-stomach but not for MUC1. We speculate that the deficiency and solid syndrome of spleen-stomach is a condition like Tai Ji symbol of dynamic equilibrium, showing the higher expression of MUC5AC but no change of MUC1 in the circumstance of Hp infection.

This study was carried out in the out patient department of Dhaka Medical College Hospital. 100 patients presented with chronic venous insufficiency during the period of January 2005 to June 2005 were studied to find out the various modes of presentation, risk factors and relationship of symptoms with age, sex and Body Mass Index of the patients. It was found that, maximum patients presented with heaviness in the leg (87%), followed by aching leg pain (75%), leg swelling (70%), cramping leg pain (68%), tiredness (48%), burning pain (43%), engorged leg vein (39%), restless leg at night (21%), throbbing leg pain (18%), itching (13%), various skin changes without active ulceration (7%) and active leg ulceration only 3% of cases. Increasing age of the patients, obesity, increasing number of pregnancy, prolonged standing and sitting position at work were found to be positively correlated with CVI. Advanced age is associated with more advanced stage of CVI according to clinical CEAP classification. There is almost equal sex distribution among the stages of CVI except in advanced stage, in stage C4, C5 and C6 there is 10 patients out of them 9 are male and only 1 is female. Relationship of symptoms with BMI of the patients were also sort out and found that, in C3 group of CEAP classification out of 61 patients 46 are obese according to BMI, of which 32 are female and 14 are male and only 17 patients have BMI within normal range, but in other group there is no significant difference in incidence between two groups.   DOI = 10.3329/jom.v9i1.1421 J MEDICINE 2008; 9 : 20-26

Pathogenic microorganisms can reside transiently or permanently in the gallbladder of cattle. Thus, during slaughter, more attention should be given to the gastrointestinal tract, especially to the accessory organ, the gallbladder. The main aim of this study was to characterize the bacterial microbiota present in bile and gallbladder epithelium of cattle slaughtered in a slaughtering plant under sanitary conditions and to evaluate the antimicrobial resistance in strains of the genus Staphylococcus. Thirty intact gallbladders were collected and the in bile and epithelium were researched for the presence of Aerobic Mesophilic Heterotrophic Bacteria (AMHB), Staphylococcusspp., total Enterobacteriaceae, Enterococcus spp. and Salmonella spp. The frequency of isolation of the microorganism mentioned above were, respectively: 23.02%, 14.39%, 13.67%, 24.46%, 0% and 24.46%. Concerning both gallbladder environments, the frequency of isolation of the microorganisms in the epithelium was 64.03%, and in the bile 35.97%, with no statistical difference, but with significant difference between the population averages. In antimicrobial susceptibility testing, strains of Staphylococcusfrom both bile and gallbladder epithelium showed sensitivity to the antimicrobials: penicillin G, ceftriaxone, chloramphenicol and gentamicin. The observation that the gallbladder supports a high frequency of microorganisms brings us to the possible fact that cattle might be a persistent carrier of pathogens of great importance to public health.

The previous studies show soil microbes play a key role in the material and nutrient cycles in the forest ecosystem, but little is known about how soil microbes respond to plant distribution, especially in the soil bacterial community in woody bamboo forests. Cephalostachyum pingbianense (Hsueh & Y.M. Yang ex Yi et al.) D.Z. Li & H.Q. Yang, 2007 is known as the only bamboo species producing shoots all year round in natural conditions. Endemic to the Dawei mountain in Yunnan of China, this species is a good case to study how soil bacteria respond to plant endemic distribution. In this work, we assayed the soil chemical properties, enzyme activity, changes in the bacterial community along the distribution range of the C. pingbianense forest. The results showed that soil nutrients at the range edge were nitrogen-rich but phosphorus-deficient, and soil pH value and soil urease activity were significantly lower than that of the central range. No significant difference was detected in soil bacterial diversity, community composition, and function between the central and marginal range of C. pingbianense forest. Notably, the relative abundance of heterotrophy bacteria, such as Variibacter and Acidothermus, in the soil of the C. pingbianense forest was significantly higher than that of the outside range, which may lead to a higher soil organic carbon mineralization rate. These results imply that abundant heterotrophy bacteria were linked to the endemism and full-year shooting in C. pingbianense. Our study is amongst the first cases demonstrating the important role of heterotrophy bacteria in the distribution formation of endemic woody bamboos in special soil habitats, and provides insight into germplasm conservation and forest management in woody bamboos.

The existence of COVID-19 pandemic brought extraordinary challenges to the stakeholders, teachers, parents, and students. Thus, the researcher believed that there is an effect of teaching-learning process in new normal education to students’ performance most especially using modular type of learning in Mathematics. With this, the study sought to determine the perception of the students regarding modular distance learning approach (MDLA) in Mathematics, identify the challenges of the students, examine the effect of MDLA to academic performance of students in Mathematics, determine the level of academic performance of students, determine the significant difference on perceptions when they grouped according to their gender and age, and determine the relationship of students’ perceptions regarding MDLA to their academic performance in Mathematics. The descriptive research design was utilized in this study. The researcher gathered one hundred seventy eight (178) grade 11 STEM students currently enrolled in MSU-Sulu Senior High School through the use of purposive random sampling. The survey questionnaire was applied in the study. Mean, frequency counts and percentage, t-test for independent samples, one-way analysis of variance (ANOVA), and person product-moment correlation were used to analyze and interpret the data. Based on the result, the study revealed that students’ perceptions agreed on using modular distance learning approach (MDLA). It means the students had positive perceptions regarding MDLA in Mathematics. The study also revealed that students agreed on using modular distance learning approach (MDLA) in Math have little challenges. It had also a positive effect to students’ performance in which students performed very satisfactory in Mathematics which means they had good quality performance. However, the study also revealed that it has no significant difference on their perceptions when they are grouped by gender and age which means the students had the same perceptions. Moreover, the findings revealed that there is no enough evidence to conclude that there is significant relationship of the students’ perceptions to the academic performance of the STEM grade 11 students using the new method of teaching modular distance learning approach (MDLA) amid COVID-19 pandemic. Therefore, the researcher concluded that the academic performances of STEM students were not affected by their perceptions in MDLA. This means that the quality of performance did not depend on their perceptions. And the researcher also concluded that this approach helped students to improve their math performance. Since it proved that this approach improved the mathematical understanding and helped the students to have good performance then the researcher recommended that MDLA must be continued in face-to-face instruction and highly recommended to use modules. Teachers guided those who need special attention and need to prepare easy type of modules in Mathematics to understand well. Any member of the family can help to guide and serve as para-teachers. Trainings, workshops, and seminars should be provided to the teachers to improve themselves and academic performances of the students.

Introduction/Objective. Maxillary incisors, when exposed during smile, are one of the most important facial features. In an attempt to overcome limitations of standard cephalometric methods, Andrews described an approach to determine ideal anteroposterior (AP) position of maxillary central incisors in smiling profile in relation to the forehead. We compared traditional Steiner cephalometric method, using surrounding skeletal landmarks, to the method proposed by Andrews, with the aim of determining whether distant but very noticeable craniofacial structures can affect our impression of tooth position. Methods. The study comprised 90 randomly selected lateral cephalograms, divided into three groups according to maxillary central incisors AP position according to Steiner cephalometric norms. The AP relationship of the maxillary central incisors was measured as a perpendicular distance from facial axis point to the nasion A line and to the vertical line through forehead facial axis point respectively. Student?s t-test and Pearson?s correlation were used to compare tested variables. Results. There was statistically significant difference between two methods (p = 0.01108). According to the Steiner method 46.67% subjects had retrusive incisors and 53.33% subjects had protrusion. Andrews?s method showed different results; 35.56% subjects had retrusion, while 64.4% had protrusion. Conclusion. The method proposed by Andrews showed consistently more protrusion than the traditional cephalometric method according to Steiner. Slightly retruded position of maxillary central incisors according to Steiner analysis does not always imply poor facial esthetics, if they have favorable position to the forehead. Low levels of correlation indicate that we should never rely on just one set of parameters.

ABSTRACT Objective: To determine the relationship of the surgeon handedness and operative site laterality on operative duration and hearing improvement in otologic surgery, and to further explore whether this relationship may be related to surgeon experience. Methods:Design: Retrospective CohortSetting: Tertiary Private Teaching HospitalParticipants: Seventy-three (73) patients aged 18 to 65 years old who underwent primary ear surgery under general anesthesia between January 2016 and December 2019 were retrospectively divided into two groups: 39 contralateral and 34 ipsilateral. The operative durations and hearing improvements were compared using independent t-tests, with consideration of surgeon experience in years further stratifying patients. Results: There was no significant difference in operative duration, t(71) = 1.14, p = .26, between the contralateral (M = 281.95 minutes, SD = 71.82) and ipsilateral (M = 261.15, SD = 79.26) groups. This same pattern was more pronounced among surgeons with 10+ years of experience although there was also no significant difference in operative time, t(33) = 1.31, p = .19 for both ipsilateral and contralateral surgeries There was no statistically significant difference, t(36) = -0.72, p = .47, in overall mean hearing gain among patients in the contralateral (M = +2.22 dB, SD = 10.54) and ipsilateral (M = +5.12 dB, SD = 14.26) groups. Although the difference was also not statistically significant, t(16) = -1.94, p = .07 for contralateral (M = 0.00, SD = 5.43) and ipsilateral (M = +7.95 dB, SD = 11.52) procedures performed by surgeons with experience of 10 years or more, a mean hearing gain of +7 dB in the ipsilateral group compared to 0 dB in the contralateral group was notable. Conclusion: This study did not prove that regardless of surgeon experience, right-handed surgeons operating on the right ear and left-handed surgeons operating on the left ear have better ear surgery outcomes of operative duration and hearing improvement compared to right- handed surgeons operating on the left ear and left-handed surgeons operating on the right ear. Future studies on larger samples with more complete data may yet demonstrate this effect.

Background: Studies on the relationship of urinary sodium with overweight and obesity led to controversial results. Furthermore, no study has ever investigated the association between sodium status and obesity in Iranian adults. The present study examined the association of urinary sodium levels with overweight and obesity in adults living in Yazd, Iran. Methods: The present study recruited 240 adults randomly selected from adults, who participated in Yazd Health Study (YaHS). A 24-hour urine sample was collected from the participants. Participants' demographic information, history of chronic diseases, and smoking status were obtained. The height and weight of the participants were also assessed using standard methods. We compared the weight and body mass index (BMI) of the participants based on the urinary sodium excretion tertiles. The logistic regression model in crude and multivariable adjusted models was used to compare the odds of obesity between urinary sodium tertiles. Results: The findings showed that the mean urinary sodium was not significantly different among overweight, obese, and individuals with normal BMI (P > 0.05) using the crude and multivariable models. Furthermore, no significant difference was observed in the mean BMI according to urinary sodium excretion tertiles. In addition, the analyses showed that the sodium status was not significantly associated with odds of developing obesity in crude and in multivariable adjusted models. Conclusion: No significant relationship was seen between sodium status and overweight or obesity. Future prospective studies are highly recommended to confirm these results.

The study was designed to investigate the relationship of psychological well-being with depression and anxiety among heart patients.1 For this purpose, a sample of 200 patients was taken, including 100 men and 100 women, educated uneducated, employed and unemployed volunteers. The sample was taken from Nishtar Hospital, Combined military hospital and other private hospitals in Multan. The age range from 25 to 60 (mean age 43.085).2,3 Objective: To observe the effect of demographic variables (age, education, gender and source of finance) on psychological well-being and depression, anxiety in heart patients. Methods: 1. Low psychological well-being would be positively correlated with depression and anxiety. 2. Older age (above 50) heart patients would have low sense of psychological well-being as compared to younger age (above 35) heart patients. Results: Different statistical procedures were used to determine the relationship of psychological well-being with depression and anxiety among heart patients. Correlation was computed to see the relationship among variables. It was found that there is negative correlation between psychological well-being with depression and anxiety. Since the p-value in less than α (p-value < 0.01), so we reject null hypothesis Ho, and conclude that low psychological well-being is positively correlated with depression and anxiety. Conclusion: This study also finds out important findings on the role of stresses, feeling of worthlessness in depression and anxiety disorder. It is concluded that psychological well-being, depression and anxiety are not significant correlated with each other. Source of income or job and sex of the heart patients have significant effect on psychological well being. However there is no significant difference between men and women regarding the rate of depression and anxiety. Keywords: P-Value, Correlation, Null Hypothesis , Depression
