RESUMO

Chronic obstructive pulmonary disease (COPD) is a major public health problem. This study was done to evaluate the changes of hemoglobin concentration in COPD patients in comparison to healthy person. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Bangladesh from July 2018 to June 2019. A total number of 160 male subjects, ages ranged from 30-70 years were included in this study. Among them, eighty (80) male COPD subjects were taken as study group (Group II) and eighty (80) age matched male healthy subjects were taken as control group (Group I). Hemoglobin concentration was estimated by cyanmethemoglobin method. Data were expressed as mean (±SD) and statistical significance of difference among the group was calculated by unpaired students' 't' test. The mean±SD of hemoglobin concentration of Group I and Group II were 13.79±1.08gm/dl and 11.63±1.33gm/dl respectively. The mean ±SD of hemoglobin concentration significantly lower in study group in comparison with control group. Patients with COPD with greater changes in hemoglobin concentration causes more frequent hospitalization and increased mortality and morbidity due to COPD related complications. So, assessment of this parameter is important for early detection and prevention of complication related to COPD for leading a healthy life.

RESUMO

Plant pathogens secrete proteins, known as effectors, that function in the apoplast or inside plant cells to promote virulence. Effector recognition by cell-surface or cytosolic receptors results in the activation of defence pathways and plant immunity. Despite their importance, our general understanding of fungal effector function and recognition by immunity receptors remains poor. One complication often associated with effectors is their high sequence diversity and lack of identifiable sequence motifs precluding prediction of structure or function. In recent years, several studies have demonstrated that fungal effectors can be grouped into structural classes, despite significant sequence variation and existence across taxonomic groups. Using protein X-ray crystallography, we identify a new structural class of effectors hidden within the secreted in xylem (SIX) effectors from Fusarium oxysporum f. sp. lycopersici (Fol). The recognised effectors Avr1 (SIX4) and Avr3 (SIX1) represent the founding members of the Fol dual-domain (FOLD) effector class, with members containing two distinct domains. Using AlphaFold2, we predicted the full SIX effector repertoire of Fol and show that SIX6 and SIX13 are also FOLD effectors, which we validated experimentally for SIX6. Based on structural prediction and comparisons, we show that FOLD effectors are present within three divisions of fungi and are expanded in pathogens and symbionts. Further structural comparisons demonstrate that Fol secretes effectors that adopt a limited number of structural folds during infection of tomato. This analysis also revealed a structural relationship between transcriptionally co-regulated effector pairs. We make use of the Avr1 structure to understand its recognition by the I receptor, which leads to disease resistance in tomato. This study represents an important advance in our understanding of Fol-tomato, and by extension plant-fungal interactions, which will assist in the development of novel control and engineering strategies to combat plant pathogens.

RESUMO

Adolescence may be defined as the period from 10 to 19 years of age. Adolescence is a significant period of human growth and maturation when various changes occur and requirement of nutrients is increased in girls due to increase demands for growth. This prospective type of analytical cross-sectional study was carried out to observe the status of Hb concentration and serum total iron binding capacity (TIBC) levels among iron deficiency anemic adolescent girl. This study was conducted in the Department of Physiology, Mymensingh Medical College, Bangladesh from July 2019 to December 2020. For this purpose, 140 adolescent girl's age ranged from 10-19 years were selected in this study, among them, 70 healthy adolescent girls as control group (Group I) and 70 girls selected as study group (Group II) and they are iron deficiency anemic adolescent girls. Estimation of hemoglobin by cyanmethaemoglobin method and estimation of serum total iron binding capacity (TIBC) was determined by Ferrozine method using Globals iron and TIBC kit, UK. All data were expressed as mean ±SD and statistical significance of difference among the Group I and Group II were calculated by unpaired students''t' test. Hemoglobin (Hb) concentration significantly lowers in study group (Group II) in comparison with control group (Group I), Result is highly significant (p<0.001). Total iron binding capacity (TIBC) significantly higher in study group (Group II) in comparison with control group (Group I), Result is highly significant p<0.001). Immediate, long term and sustainable public health intervention would require for overcome the situation.

RESUMO

Type 2 diabetes mellitus is a serious public health concern because it produces considerable impact on human life and health expenditures. Overweight and obesity plays a major role in the pathogenesis of type 2 diabetes. Fasting blood sugar is the diagnostic marker for type 2 diabetes mellitus. Glycated hemoglobin is widely used as an index of mean glycemia. The aim of this study was to find out the effect of body mass index, fasting serum glucose, glycated hemoglobin in type 2 diabetic female patients in Mymensingh locality. This cross-sectional analytical type of study was carried out in the department of Physiology, Mymensingh Medical College (MMC), Mymensingh, Bangladesh from July 2022 to June 2023. A total 200 subjects age ranged between 30-59 years were selected and were grouped as control group, Group I (100, non-diabetic female) and study group, Group II (100, female diabetic patients). SPSS was used to calculate and analyzed the result. Anthropometric measurements such as height and weight taken in meter and kilogram respectively, laboratory analysis of fasting serum glucose was determined by GOD- POD method, glycated hemoglobin by fluorescence immunoassay method. Results were expressed as mean (± SD) and by unpaired Student's 't' test. The mean (± SD) of BMI of control group (non-diabetic female) and study group (female diabetic patients) were 22.01±1.50 and 26.86±2.00 kg/m² respectively. In study group BMI was increased in comparison to control group. The mean (± SD) of fasting serum glucose of control group (non-diabetic female) and study group (female diabetic patients) were 4.36±0.84 and 8.25±2.52 mmol/L respectively. In study group fasting serum glucose was increased in comparison to control group. The mean (± SD) of glycated hemoglobin of control group (non-diabetic female) and study group (female diabetic patients) were 5.07±0.47 and 7.45±1.34 % respectively. In study group glycated hemoglobin was increased in comparison to control group. In this study we found that body mass index, fasting serum glucose, glycated hemoglobin was significant in study group (female type 2 diabetic patients) in comparison to control group (healthy female adults of same age group). Therefore, by this study we recommended that for prevention of complications related to type 2 diabetes mellitus routine estimation of these parameters is important.

RESUMO

Menopause is a normal physiological period that is characterized by the completely stoppage of endometrial cycles in women between the age of 45-55 years due to lack of ovarian follicular function. Several postmenopausal syndromes such as hot flushes, night sweats, vaginal dryness, depression, irritability, headache, and sleep disturbance can occur more frequently in this period which hampers the standard of life. This study was done to assess body mass index and fasting serum glucose changes in postmenopausal women in contrast with reproductive women. This cross-sectional analytical type of study was conducted in the Department of Physiology, Mymensingh Medical College, Bangladesh from January 2021 to December 2021. Total 140 women subject's age ranged between 25-65 years were involved in this study. Among them 25-45 years aged 70 (Seventy) reproductive women were involved as control group (Group I) and 45-65 years aged 70 (Seventy) postmenopausal women were taken as study group (Group II). By Anthropometric measurements, Body Mass Index (BMI) such as height and weight were taken in meter and kilogram respectively and fasting serum glucose was measured by GOD-PAP method. Results were expressed as mean (±SD) and by unpaired Student's 't' test, statistical significance of difference among the group was calculated. The mean±SD of BMI of Group I and Group II were 23.05±4.43kg/m² and 29.01±3.12kg/m² respectively. The mean±SD of body mass index is notably increase in study group in contrast with control group. The mean±SD of fasting serum glucose of control Group I and study Group II were 4.77±2.04mmol/l and 6.11±1.61mmol/l respectively. In study Group II fasting serum glucose was increased. Due to increased fasting serum glucose caused by lower level of female sex hormones specially estrogen hormone increased chance of cardiovascular diseases in postmenopausal women. Assessment of these parameters are important for early detection and prevention of complication related to high BMI and fasting serum glucose level for leading a better life.

RESUMO

Context The cerebellum is a part of the hindbrain and consists of cortical gray matter (GM) at the surface and a medullary core of white matter (WM). The GM contains a cell body of neurons that helps process and transmit any command type through nerve fibers found in the WM. The main functions of GM in the central nervous system empower persons to control motor activity, recollection, and passion. So, this research aims to assess the thickness of GM at the summit and bottom of folia by histologically studying the cerebellum cortex. Methods The collection of data was a descriptive type of cross-sectional study. The method was the purposive type. This study was conducted from August 2016 to March 2017, and the research was carried out at Mymensingh Medical College's Department of Anatomy, Bangladesh. Specimens containing cerebellum were preserved from Bangladeshi cadavers according to sexes and ages ranging in years. We chose fresh specimens from people who died within the last 12 hours and preserved them in 10% formol saline. The size of the tissue that was collected for the histological study was not more than 2 cm2 and not more than 4-5 mm thick. Then the tissue was placed in 10% formol saline. This fluid was used for quick fixation and partial dehydration of the tissue. After dehydration, each tissue segment is processed for infiltration and embedding separately. Every section was stained with hematoxylin and eosin stain (H&E) before being coated with dibutyl phthalate polystyrene xylene (DPX) coverslips on slides. Result The mean (±SD) thickness of GM at the summit of folium was 886.2±29.7µm in Group A, 925.2±25.9µm in Group B, 912.7±22.3µm in Group C, and 839.9±40.7µm in Group D. Mean (±SD) GM thickness at the bottom of the fissure was 395.6±12.2 µm, 403.9±26.0µm, 380.4±23.4 µm, and 375.8±28.8 µm in Groups A, B, C, and D respectively. Conclusion The thickness of the cortex is an essential factor in the normal development process, and it was similar in the current study. Normal aging, Alzheimer's disease, and other dementias cause reduced GM which makes the cortical sheet thin. Huntington's disease, corticobasal degeneration, amyotrophic lateral sclerosis, and schizophrenia are all examples of neurological disorders. Cortical thinning is typically locally localized, and the progression of atrophy can thus disclose much about a disease's history and causal variables. The present study correspondingly found that GM was reduced after the age of 50 years onward. Furthermore, longitudinal investigations of cortical atrophy have the potential to be extremely useful in measuring the efficacy of a wide range of treatments.

RESUMO

Menopause, in between the age of 45-55 years every woman faces it, that means completely stoppage of menstruation because the decrease level of estrogen from the normal level. In this period the quality life is disturbed due to hormonal imbalance specially estrogen. This study was done to evaluate the changes of body mass index and blood pressure in post-menopausal women in comparison to reproductive women. This cross-sectional analytical type of study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh and the period is from January 2021 to December 2021. Total 140 women subjects age ranged between 25-65 years were involved in this study. Among them 70 post-menopausal women (45-65 years) were involved as study group (Group II) and 70 (seventy) reproductive women (25-45 years) were taken as control group (Group I). By anthropometric measurements, Body Mass Index (BMI) such as height and weight were taken in meter and kilogram respectively and systolic and diastolic blood pressure by aneroid sphygmomanometer (ALPK2, Japan). Findings were expressed as mean±SD and by unpaired student's 't' test, analytical significance of difference among the group was calculated. The mean±SD of BMI of Group I and Group II were 23.05±4.43kg/m² and 29.01±3.12kg/m² respectively. The mean±SD of body mass index is significantly higher in study group in comparison with control group. The average (±SD) of systolic blood pressure of control group I and study group II were 118.29±10.00 mm of Hg & 134.00±11.91 mm of Hg respectively. The mean±SD of systolic blood pressure was significantly higher in study group in comparison with control group. The mean±SD of diastolic blood pressure of control group I and study Group II were 79.21±6.46 mm of Hg and 89.00±6.23 mm of Hg respectively. The mean±SD of diastolic blood pressure was significantly higher in study group in comparison with control group. Post-menopausal women with high systolic and diastolic pressure have a chance of development of cardiovascular diseases, stroke. So assessment of these parameters are important for early detection and prevention of complication related to high BMI and Blood Pressure for leading a healthy life.

RESUMO

The oral contraceptive pill, 'the pill', was introduced in the starting of the 1960s. Presently, worldwide about 100 million women are current users of combined hormonal contraceptives (COC) most frequently used in the western world. The most frequently used agents are a combination of drugs containing both the estrogen and progesterone. This combination is considered to be highly efficacious, generally considered 99.9% and a use effectiveness of 97.0% to 98.0%. This study was done to evaluate the changes of Body Mass Index (BMI) and Blood pressure ( BP) in combined oral contraceptive pill users in comparison to non- users. This cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2021 to June 2022. Total number of 120 reproductive aged women, age ranged from 15-55 years was included in this study. Among them, sixty (60) combined oral contraceptive pill users subjects were taken as study group (Group II) and sixty (60) age matched oral pill non users subjects were taken as control group (Group I). Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired students' 't' test and Pearson's correlation coefficient test. The mean±SD of BMI of control group (Group I) and study group (Group II) were 22.50±1.50 kg/m² and 27.64±1.28 kg/m² respectively. In study group (Group II) BMI was increased. Result is statistically highly significant (p<0.001). The mean±SD of systolic blood pressure of control group (Group I) and study group (Group II) were 111.17±8.51 mm of Hg and 127.50±6.14 mm of Hg respectively. In this study the mean±SD of diastolic blood pressure of control group (Group I and study group (Group II) were 75.58±5.05mm of Hg and 87.00±4.89 mm of Hg respectively. In study group (Group II) diastolic blood pressure was increased. Result is statistically highly significant (p<0.001). So the assessment of this parameter is important for early detection and prevention of complication related to combined oral contraceptive pill use for leading a healthy life.

RESUMO

Hypertension or elevated blood pressure is a serious medical condition that significantly increases the risks of heart, brain, kidney and other diseases. An estimated 1.28 billion adults aged 30-79 years worldwide have hypertension, most (two-thirds) living in low- and middle-income countries. An estimated 46.0% of adults with hypertension are unaware that they have the condition. In Bangladesh, 21.3 million of the adult population has hypertension and that is 21.0% of total population. About half of them (48.7%) with hypertension are diagnosed and 34.9% are under treatment. One of the global targets for non communicable diseases is to reduce the prevalence of hypertension by 33.0% between 2010 and 2030. This study was done to evaluate the effects of hypertension and to find out the major complications occurring due to hypertension. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. A total number of 120 male subjects, age ranged from 20-59 years was included in this study. Among them, sixty (60) hypertensive subjects were taken as study group (Group II) and sixty (60) ages matched normotensive adult male subjects were taken as control group (Group I). The results were calculated and analyzed by using Statistical package for social science (SPSS). Anthropometric measurements such as height and weight were taken in meter and kilogram respectively. Systolic and diastolic blood pressure were measured by Aneroid Sphygmomanometer (ALPK2, Japan), laboratory analysis of fasting serum total cholesterol by CHOD-POD method, fasting serum triglycerides by GPO-POD method. In this study we found that in study group Mean±SD of body mass index (29.36±2.60, p<0.001), fasting serum total cholesterol (232.05±11.18, p<0.001) and fasting serum triglycerides (180.67±19.44, p<0.001) which were significantly increased with comparison to control group. It's concluded from this study we recommended that routine estimation of these parameters is important for prevention of complication related to hypertension for leading a healthy life.

RESUMO

BACKGROUND: Each vertebra is formed by combining the distal portion of one somite and the cranial half of its proximate part. HOX genes regulate the patterning of the shapes of the non-identical spinal column. In the sacral area, anatomical dissimilarity is on account of the distinct shape of the sacral hiatus and the outright non-subsistence of the posticous embankment of the sacral neural tube, which is a consequence of the non-fulfillment of bonding of lamina of all sacral vertebrae. After that, the meninges and the spinal nerve are unprotected and undiagnosable without an X-ray examination. Therefore, it is difficult to detect the reasons for caudal block failure, low back pain, etc. The current research aimed to improve the proficiency of anatomical and developmental errors of the dorsal wall of the sacrum. METHODS: This study was conducted on 60 dried adult sacra of unknown sexes from the stock wing of Anatomy, Sylhet MAG Osmani Medical College, Bangladesh, from 2017 to 2018. The undefined gender of the sacrum was identified. RESULTS: Out of 60 sacra, 30 (50.0%) were found to be that of males and 30 (50.0%) of females. Among the study samples, only three (5%) samples presented a complete absence of the sacrum's dorsal wall and and incidence among males was higher than females. CONCLUSION: This type of sacral aberration has paramount clinical importance. Thereby avoiding caudal epidural block-connected sufferings and backbone operative procedures. The expertise regarding the anatomical variation of sacral hiatus is necessary to reduce the failure rate during caudal epidural anesthesia, helps orthopedic surgeons diagnose the cause of low back pain or in surgical situations, and helps pediatricians deal with congenital anomalies such as meningocele and myelomeningocele.

RESUMO

Background Axial length (AL) and corneal curvature (CC) are one of the furthest critical parameters for optometry and oculoplastic surgery. These two variables are crucial in biometry for accurately measuring the power of the intraocular lens in cataract surgery. This research aimed to determine the association linking axial length and corneal curvature with demographic characteristics in emmetropic eyes of Bangladeshi people. Methods This descriptive cross-sectional research was carried out among 200 emmetropic eyes of Bangladeshi people attending the Department of Ophthalmology at Rajshahi Medical College, Bangladesh, with different eye conditions, between July 2017 and June 2018. Data was gathered by conducting person-to-person interviews, checking visual activity using the Snellen chart, and measuring corneal curvature using an auto-keratometer and axial eyeball length using A-scan ultrasonography. Results A total of 200 attendances were studied, 90 males and 110 females. All were emmetropic. The age range was 21-52 years, and the highest contributors were in the 21-30-year age group. The association between right axial length and right corneal curvature shows a negative relation among both sexes. It was -0.61 (ß-coefficient (ß-coff)), and highly significant in females at -0.89 (ß-coff). Additionally, the association between left axial length and left corneal curvature shows a negative relation of -0.65 (ß-coff), which was again highly significant in females at -0.87 (ß-coff). Both were not significant in males. There was no significant association linking axial length and eye axis in both sexes. The multivariate regression model was used to assess the p-value, and the regression model was adjusted by age. Conclusion Optical parametric measurement is a noninvasive diagnostic and assessment tool that might help in the actual measurement of intraocular lens implantation in cataract surgery and may also provide supplementary information to the researcher domain.

RESUMO

Adolescence explained as a period of age between 10 to 19 years. This is a major contributing period to build up the health of girls. Ferritin is an intracellular protein that contains iron and releases it in a controlled fashion and it reflects body iron stores and systemic inflammation during adolescent period. It is considered the best single test for the diagnosis of iron deficiency anemia during adolescent because its concentration is directly proportional to total body iron stores in adolescent period. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh to evaluate the changes of serum ferritin levels among iron deficient anemic adolescent girls in comparison to healthy adolescent girls in Bangladesh. This was a cross sectional, prospective, analytical type of study. This study ranged from 10-19 years of adolescent girls. Seventy (70) healthy adolescent girls, as control group (Group I). Seventy (70) iron deficiency anemic adolescent girls as study group (Group II). Serum ferritin was estimated by Micro-particle Enzyme Immunoassay Test Kit. Data were expressed as mean (±SD). Statistical significance of difference among the Group I and Group II were calculated by unpaired students 't' test. The mean±SD level of serum ferritin among Group I and Group II were 26.22±4.03µg/L and 13.33±3.18µg/L respectively. Mean values ±SD of serum ferritin significantly lower in (Group II) in comparison with (Group I). Higher numbers of adolescent girls are still suffering from anemia along with low level of serum ferritin in Bangladesh. For combat this situation, immediate, sustainable and long term public health intervention and nutritional supplementation must be required.

RESUMO

Patients often present with chronic kidney disease (CKD) complicated with hypocalcaemia. Lower serum calcium is independently associated with chronic kidney disease. Aim of this study was to assess of serum calcium level in chronic kidney diseased patients in order to compare this parameter with healthy subjects. This analytical type of cross-sectional study was carried out in the Physiology department, Mymensingh Medical College, Mymensingh, Bangladesh from July 2018 to June 2019. A total number of 200 subjects, age range 30-70 year were included in this study. Among 200 subjects, 100 healthy were taken as control group (Group I) and 100 chronic kidney diseased patients were taken as study group (Group II). Control group (Group I) subdivided into male healthy subject (Group IA) and female healthy subject (Group IB). Also study group (Group II) subdivided into male chronic kidney diseased patient (Group IIA) and female chronic kidney diseased patient (Group IIB). The results were calculated and analyzed by using SPSS version-21. Expression of data as mean±SE and statistical significance of difference among the group was calculated by unpaired student's 't' test. In this study we found that mean±SE serum calcium of Group IA and Group IIA were 9.60±0.09mg/dl & 8.04±0.03mg/dl respectively. The mean±SE serum calcium of Group IB and Group IIB were 9.38±0.096mg/dl & 8.19±0.05mg/dl respectively. Serum calcium was significantly decreased in study groups in comparison with control groups (p<0.001). By this study we therefore recommended that routine estimation of this parameter is important for prevention of complication related to chronic kidney disease for leading a healthy life.

RESUMO

The most common cause of premature death in developing countries like Bangladesh is ischaemic heart disease. Cardiac troponin-I (cTnI) is 100 percent tissue specific for the myocardium which has been shown to be a very sensitive and specific biomarker for acute myocardial infarction. As acute myocardial infarction is a stressful condition so, plasma glucose level may also increase in this condition which is stress hyperglycemia and also plasma glucose level may be used for prediction of outcome as it is a cheap and easy available test. The aim of the study is to investigate the impact of the elevation of troponin-I level with plasma glucose level of non-diabetic patients in ST-elevation myocardial infarction. This study which was comparative type of analytical and cross- sectional study carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. Data was collected from Cardiology Department of Mymensingh Medical College Hospital, Mymensingh. A total number of 70 subjects participated in this study and were grouped as normoglycemic ST elevation myocardial infarction- Control group (Group I) and non-diabetic hyperglycemic ST elevation myocardial infarction- Study group (Group II). The results were calculated and analyzed by using SPSS. Serum troponin-I was measured by Fluorescence Immunoassay (FIA) and plasma glucose estimated by GOD-PAP method. Data were expressed in mean±SD and statistical significance of difference among the groups were calculated by unpaired Student's 't' test. The correlation between different parameter was done by Pearson's correlation coefficient test. In this study, the result suggests that there is significant positive association between serum troponin-I and plasma glucose level in study group (hyperglycemic non-diabetic STEMI) in comparison to control group (normoglycemic STEMI). So, by this study we recommend that routine estimation of these parameters is important for prevention of complications related to acute myocardial infarction.

The serum Alanine Transaminase (ALT) activity has been regarded as a reliable and sensitive marker of liver disease. In the context of obesity ALT may also be a good indicator of overall health. Obesity has been reported as a risk factor associated with elevation of ALT, which is a surrogate marker of Non-alcoholic fatty liver disease (NAFLD). Elevated ALT may correlate with the severity of NAFLD in obese female. This study was done to evaluate the changes of serum ALT in obese female age ranged 30-60 years in comparison to normal healthy female of same age. At the same time we can know the relationship between body mass index and serum ALT concentration in obese female. This analytical cross-sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2020 to December 2020. A total number of 100 female subjects were included in this study. Among them fifty (50) normal healthy female were taken as control group (Group I) and fifty (50) obese female were taken as study group (Group II). The level of serum ALT was determined by Ultra violet (UV) method. Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired Student's 't' test. Pearson's correlation coefficient test was done to find the correlation of serum ALT with BMI by using SPSS (version 21.0). During interpretation of results, p values of <0.001 were considered as statistically highly significant. In this study, serum level of ALT was significantly higher (p<0.001) in obese female compared to those of healthy control female. In addition, there is a positive correlation of serum ALT with BMI. From the results of the present study, it can be concluded that, elevated ALT was significantly associated with high BMI as well as with other feature of NAFLD.

RESUMO

Menopause is one of the natural parts of women's life when menstrual cycle stops due to lack of estrogen, which occurs in middle age. Various health problems occur in this period which hampers quality of life. This study was done to evaluate the changes of body mass index and serum calcium level in post-menopausal women in comparison to reproductive women. This cross-sectional analytical type of study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. A total number of 140 female subjects age ranged from 25-65 years were included in this study. Among them 70 (seventy) postmenopausal woman (45-65 years) were taken as study group (Group II) and 70 (seventy) reproductive women (25-45 years) were taken as control group (Group I). Body mass index was measured by Anthropometric measurements such as height and weight taken in meter and kilogram respectively and Serum calcium level was measured by colorimetric method with O-Cresolftalein-complexone (OCC). Data were expressed as mean (±SD) and statistical significance of difference among the group was calculated by unpaired Student's 't' test. The mean±SD of BMI of Group I and Group II were 23.05±4.43 kg/m² and 29.01±3.12 kg/m² respectively. The mean±SD of body mass index is significantly higher in study group in comparison with control group. Serum calcium of Group I and Group II were 10.95±0.77 mg/dl and 7.99±0.55 mg/dl respectively. The mean±SD of serum calcium level was significantly lower in study group in comparison with control group. Post-menopausal women with low serum calcium level have a chance of development of osteoporosis. So, assessment of this parameter is important for early detection and prevention of complication related to low serum calcium level for leading a sound life.

RESUMO

Type-2 diabetes mellitus accounts for 90-95% of all diabetes. There is a Correlation between Fasting Serum Glucose and Serum Zinc level in patients with Type-2 Diabetes Mellitus. This study was done to assess the relationship of Fasting Serum Glucose and Serum Zinc in type-2 diabetic patients in order to compare this parameter with healthy subjects. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2018 to June 2019. A total number of 140 subjects, age ranged from 35-65 years was included in this study. Among them, seventy (70) type-2 diabetic patients were taken as study group (Group II) and seventy (70) ages matched healthy subjects were taken as control group (Group I). Group I again subdivided into control group male (Group IA) and control group female (Group IB). Group II also subdivided into study group male (Group IIA) and study group female (Group IIB). Pearson correlation coefficient test is done to correlate the relationship between fasting serum glucose (FSG) and serum zinc. In this study we found that serum zinc level was decreased in study groups in comparison with control groups. Therefore, by this study we recommended that routine estimation of this parameter is important for prevention of complication related to diabetes for leading a healthy life.

RESUMO

The aim of the study was to assess the status of body mass index (BMI) and blood pressure in elderly male in comparison to younger male and to study the association of BMI and blood pressure with age. This analytical type of cross-sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2019 to December 2019. A total number of 140 male subjects were included in this study. Among them seventy (70) younger males were taken as control group (Group I) and seventy (70) elderly males were taken as study group (Group II). Body mass index (BMI) was calculated as the weight in kilograms divided by the square of the height in meters (kg/m²). Systolic and diastolic blood pressure was measured by aneroid sphygmomanometer (ALPK2, Japan). Data were expressed as Mean±SD and statistical significance of difference among the group was calculated by unpaired student's 't' test. Pearson's correlation coefficient test was done to find the correlation of BMI, systolic blood pressure (SBP) & diastolic blood pressure (DBP) with age. In this study we found that mean BMI, systolic blood pressure & diastolic blood pressure were significantly higher in elderly male persons in comparison to younger male. Although the magnitude of correlation differed, we found that BMI, systolic blood pressure & diastolic blood pressure were positively correlated with age of the subjects. Based on the study carried out it can be concluded that due to aging process geriatric populations are more prone to development of hypertension and other cardiovascular complications than younger individuals.

RESUMO

Adolescent girls are vulnerable in underdeveloped and developing countries due to having public health problems regarding iron deficiency anaemia. As zinc acts as a cofactor in iron metabolism, so the deficiency of this trace element is associated with iron deficiency anaemia. This study was done to evaluate the changes of serum iron and serum zinc levels among iron deficient anaemic adolescent girls in comparison to healthy adolescent girls in Bangladesh. This prospective type of analytical cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2019 to December 2020. Total number of 140 adolescent girl's age ranged from10-19 years included in this study. Among them, 70 healthy adolescent girls, were taken as control group (Group I). Remaining 70 Adolescent girls with iron deficiency anaemia (IDA) were taken as study group (Group II). Estimation of serum iron was determined by Ferrozine method using Globals iron kit, UK. Serum zinc levels were determined by colorimetric method with reagents. All data were expressed as mean (±SD) and statistical significance of difference among the group I ( healthy adolescent girls) and group II (adolescent girls with iron deficiency anaemia) were calculated by unpaired students' 't' test. Correlation of serum iron with serum zinc was done by Pearson's correlation coefficient test. The mean values (±SD) of serum iron level of Group I and Group II were 69.06±18.11µg/dl & 15.61±9.12µg/dl respectively. Mean values (±SD) of serum iron significantly lower in study group (Group II) in comparison with control group (Group I). The mean (±SD) of serum zinc level of Group I and Group II were 75.48±14.26µg/dl & 33.27±12.94µg/dl respectively. Mean value (±SD) of serum zinc levels were significantly lower in study group (Group II) in comparison with control group (Group I). Serum zinc level was positively correlated with serum iron and that was statistically significant. The deficiency of iron does not occur alone; rather it is typically associated and developed with hypozincemia. The study suggests on supplementing iron along with zinc to correct the deficiency especially in adolescent girls when their metabolic demand is high.

RESUMO

Plant pathogens cause disease through secreted effector proteins, which act to promote infection. Typically, the sequences of effectors provide little functional information and further targeted experimentation is required. Here, we utilized a structure/function approach to study SnTox3, an effector from the necrotrophic fungal pathogen Parastagonospora nodorum, which causes cell death in wheat-lines carrying the sensitivity gene Snn3. We developed a workflow for the production of SnTox3 in a heterologous host that enabled crystal structure determination and functional studies. We show this approach can be successfully applied to study effectors from other pathogenic fungi. The ß-barrel fold of SnTox3 is a novel fold among fungal effectors. Structure-guided mutagenesis enabled the identification of residues required for Snn3 recognition. SnTox3 is a pre-pro-protein, and the pro-domain of SnTox3 can be cleaved in vitro by the protease Kex2. Complementing this, an in silico study uncovered the prevalence of a conserved motif (LxxR) in an expanded set of putative pro-domain-containing fungal effectors, some of which can be cleaved by Kex2 in vitro. Our in vitro and in silico study suggests that Kex2-processed pro-domain (designated here as K2PP) effectors are common in fungi and this may have broad implications for the approaches used to study their functions.
