Amia Calva

The age of 80 bowfins (Amia calva L.) from the Montreal area has been read from the scales, the gular plate, and the otoliths. Both sexes have the same growth rate. The growth in length of all specimens collected can be summarized in one logarithmic equation: log L = 2.35137 + 0.54922 log A, where L is the total length (in mm) and A the age group. All the age groups can then be described by a particular measured mean length and also by a back-calculated mean length. The ponderal growth is obtained first from the mean weight of different classes, and then from the length–weight relation: log P = −4.961 + 2.992 log L, in which P is the weight (in g) and L the mean length (in mm) determined by back calculation. Maximum length and weight recorded were 870 mm and 6800 g respectively; a 12-year life span seems to be rarely exceeded. The results are compared with those available in the literature.

Abstract Background Early diagnosis and treatment of ACS can reduce the risk of complications and death. Delay calling for help can increase morbidity and mortality. It is unclear which age group among patients with acute coronary syndrome tend to delay their call for help. Results Our observational retrospective study showed that men and women in their 50s and 40s respectively tend to delay their call for help from symptoms onset. For the former, the mean time delays (590 ± 71.1 min), whereas for the latter it was (1084 ± 120.1 min). Moreover, these groups tend to have a longer time delay between symptoms onset and arrival at the hospital. Among deaths, we observed that the death rate was proportional to the time delay, which is not unexpected. Next step, we plan to perform a qualitative study in the form of questionnaires to target the individuals with a high risk of CVD within these age groups. Conclusion Middle age group of both genders tend to delay their call for help when they experience symptoms of ACS; moreover, regardless of the age, the longer the delay, the higher the mortality rate. The results of this study gave us a better understanding of our local population and will pave the road for a well-structured teaching programme for them to minimise the time delay for calling for help.

ABSTRACT: The aim of this research was to measure the intraocular pressure (IOP) of normal chinchilla eyes using the rebound tonometer. A further aim was to assess whether there were differences in the values of intraocular pressure in relation to animals age, gender and time of day. Thirty-six chinchillas were divided into three groups of 12 chinchillas each, by age: Group I (2-6-month-old), Group II (20 and 34 months) and Group III (37 and 135 months). Ophthalmic examination was performed previously by Schirmer tear test, slit lamp biomicroscopy, indirect ophthalmoscopy and fluorescein test in all chinchillas. Three measurements of intraocular pressure were assessed on the same day (7, 12 and 19h). Tonometry was performed on both eyes using the rebound tonometer after calibration in "p" mode. Statistical analysis was performed with SigmaPlot for Windows. The mean IOP for groups I, II and III were 2.47±0.581mmHg, 2.47±0.581mmHg and 2.51±0.531mmHg, respectively. No significant differences were reported between age and IOP and no significant differences were reported between the time of day and IOP. The IOP in chinchillas did not differ significantly between genders or ages of the animals, and did not change with time of day.

 Background: Acute appendicitis is very common surgical cause of acute abdomen and needs surgical removal either by laparoscopic or open appendicectomy. The aim of this study is to compare frequency of surgical site infection (SSI) in patients undergoing laparoscopic and open appendicectomy. Materials and Methods: The study was prospective study conducted in NMCTH, Biratnagar. Total 200 patients with diagnosis of acute appendicitis admitted through the emergency department of our hospital were included in the study. The patients were randomly allocated in two groups: Laparoscopic appendicectomy group (LA) and Open appendicectomy group (OA). Both groups underwent successful emergency appendicectomy. Wound infections in terms of surgical site infection (SSI) if present were recorded. All age groups and both sexes were included.  Results: Two hundred patients underwent appendicectomy, one hundred Laparoscopic appendicectomy (LA) and another hundred open appendicectomy (OA). The mean age of patients with acute appendicitis was 30.63±16.14 years with minimum of 6 years and maximum of 77 years. The highest number of patients were in age group of 10 to 20 years (29.5%). In LA group SSI noted in 3 patients (3%) whereas in OA group it was found in 12 patients (12%). Conclusion: Laparoscopic appendicectomy is better and offers great advantages in terms of SSI as compared to Open appendicectomy.

ABSTRACT BACKGROUND: The bacterium Helicobacter pylori is strongly associated with the development of gastric adenocarcinoma. Currently, the prevalence in developed countries is 40%, but this value increases considerably in developing countries, which can reach rates bigger than 90%. OBJECTIVE: The objective of this study was to determine the mean and annual prevalence of Helicobacter pylori infection in patients from Itajaí during the period from July 1992 to April 2016, as well as the gender and age groups most affected. METHODS: After consent of the clinical director of the Gastroclinica Itajaí and confidentiality commitment about the research, the database of the Endoscopy Service of the clinic was evaluated. All the patients who underwent their first upper digestive endoscopy with urease test and/or histological analysis were included. The data were submitted to statistical analysis of prevalence by gender, age group and years of study, with subsequent correction through the confidence interval. RESULTS: The mean prevalence of Helicobacter pylori infection thru all years of study was 50.07%. With the calculation of the annual prevalences, it was evident the gradual reduction of infection in the population of Itajaí, that was 81.3% in 1992, declining to 33% in the year of 2016. When classifying the prevalence of infection by gender, it was higher in males (53.59%), and gender distribution by age group showed no statistically significant difference among genders between the ages of 40 and 80 years. In relation to the age group, the highest prevalence was in the group between 40 and 49 years. CONCLUSION: Although this study is retrospective and based on endoscopic database analysis, without access to clinical data of patients such as prior use of proton pump inhibitor and antibiotics to endoscopy, its results are important because they may reflect the current panorama of Helicobacter pylori infection in the city under study, where it has been presenting a gradual reduction of prevalence over the years, with current rates similar to that of developed countries (33%). Future studies are needed to confirm our data.

Following our earlier reports on one-year-old oyster populations of Prince Edward Island (Singh and Zouros, 1978, 1981; Zouros et al., 1980), cohorts of three-year classes were studied from Cape Breton, Nova Scotia. Random samples of about 200 individuals from each year class were analyzed for four polymorphic enzymes. A number of generalizations emerged. There was a general deficiency of heterozygotes in the three age groups and this deficiency decreased with age (reflecting reduction in heterozygote deficiency). This suggests genotype-specific mortality during ontogeny. The deficiency of heterozygotes was more pronounced in slower growing, lighter individuals than in faster growing, heavier individuals. The number of heterozygous loci per individual was positively correlated with mean growth rate. The variance in weight was lower in heterozygotes; it decreased with increase in number of heterozygous loci in a given age group. Overdominance in growth rate appears to be the most plausible explanation for these observations.

Visual perception is the process by which individuals assign meaning, understanding, and interpretation to what they have seen. The aim of this study was to determine the visual perceptual skills of typically developing Indian children on MVPT-4. A sample of 180 typically developing Indian students were included in the study using convenience sampling method. They were divided in six age groups with age ranging from 6years to 12 years with 30 children in each age group. It was found that visual perceptual skills of typically developing Indian children in 6-12 years of age group can be assessed using MVPT-4. Analysis was done using One-way Anova to compare the mean raw score of each age group. There was a significant difference between the age groups at statistical value of p< 0.001. The score improved with age, signifying refined and matured visual perceptual skills in older children. Age influences visual-perceptual skills of these children. This study also provides a foundation for further researches and highlights the importance of MVPT-4 as a screening tool to be used by the occupational therapist in order to assess the visual perceptual skills of children.

Background : The study was carried out in the department of neurosurgery, BSMMU, Dhaka during the period of July 2003 to June 2005. Objective: This study was done to elucidate the relationship between age groups and histopathologicas subtypes in case of intracranial astrocytoma patients. For this purpose, a total number of 44 cases were studied. Results: The mean age of all the patients was 33.1 years (range:1-65 years). The highest incidence was found in the age group of 20 years or below group. Male were more commonly effected than female. WHO grade I astrocytoma was the commonest type. Mean age of low grade astrocytoma (WHO grade II) and glioblastoma were nearly similar to other studies, but the mean age of presentation of grade I astrocytomas patients was little late and for anaplastic actrocytoma a little early in comparison to other study. Conclusion: This showed subtype of astrocytoma has definitive relation to age. Bangladesh Journal of Neuroscience 2011; Vol. 27 (2) : 87-93 DOI: http://dx.doi.org/10.3329/bjn.v27i2.17575
