RESUMO

Investigating enzyme activity is central to our understanding of biological function, and the design of biocatalysts continues to find applications in synthesis. While a role for active site residues can be proposed based on structure and mechanism, our understanding of the catalytic importance for residues surrounding the active site is less well understood. In triosephosphate isomerase (TIM), Glu97 is situated adjacent to the active site and is found in essentially all sequences. Prior studies reported mutation of Glu97 to Asp and Gln in TIM from Plasmodium falciparum (PfTIM) led to a 100- and 4000-fold decrease in activity, respectively, while the E97D mutation in TIM from Gallus gallus (cTIM) had no effect on activity. To investigate further the question of how mutations in essentially superimposable structures give different effects, we mutated E97 in TIM from Trypanosoma brucei brucei (TbbTIM), Saccharomyces cerevisiae (yTIM), and human (hTIM). The E97D, E97A, and E97Q mutations led to a ∼three-tenfold decrease in activity, a modest effect compared to the 102-103-fold effect in PfTIM. CD and fluorescence studies showed the overall structures for the mutants were essentially unchanged. Structural analysis shows that several residues surrounding E97 differ between PfTIM and TIM from the other organisms, and rearrangements or mispositioning of residues in PfTIM may lead to the different rate effects. The results illustrate the interplay of active site and surrounding residues in affecting catalysis and highlight that understanding of the role of residues surrounding the active site may aid in the incorporation of favorable or avoidance of unfavorable interactions when designing enzymes.

RESUMO

Obesity is a disorder of body weight regulatory systems characterized by an accumulation of excess body fat. World Health Organization recommended that 66% of deaths now occur in developing countries and recognizes obesity as a leading risk factor. Obesity is associated with chronic, low grade, systemic inflammation. The inflammatory state play a causal role in the development of insulin resistance, type 2 diabetes and the metabolic syndrome. This descriptive type of cross sectional study will design to evaluate the relation between obesity with hemoglobin concentration. One hundred obese and 100 normal weight persons from both sexes, aged between 25 to 60 years will be selected from Mymensingh Medical College, Mymensingh and locality from July 2014 to January 2016. Data are collected through a simple questionnaire after informed consent taken. The result was calculated and analyzed by using SPSS (statistical package for social science, version 11.5). Statistical significance of difference between two groups were evaluated by unpaired Student's 't' test. Data were expressed as Mean±SE. P value less than 0.05 was taken as the level of significance. Anthropometric measurements such as height and weight were taken in meter and kilogram respectively. Pulse, systolic and diastolic blood pressure was measured by aneroid sphygmomanometer (ALPK2, Japan), laboratory analysis of hemoglobin was done by Cyanmethemoglobin Method. In this study we found that hemoglobin concentration is significantly increased in both male and female obese persons.

RESUMO

Asthma is a chronic inflammatory disorder of the airways, in which many cells and cellular elements play a role. Asthma is one of the most common diseases globally and currently affects 300 million people. Asthma and obesity have an enormous impact on public health. Since the 1990s, various studies have shown a correlation between an increase in body mass index (BMI) and asthma prevalence. This descriptive type of cross sectional study was done to find the levels of BMI in adult asthmatic patients and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty male and 50 female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. BMI were calculated by weight in kg divided by height in square meter (m²). For statistical analysis unpaired Student's 't' test was used. Mean BMI were significantly increased in both study group in comparison to control group and the result was statistically significant (p<0.001). From this study, it may be concluded that increase body mass index that is overweight or obesity can increase the prevalence and incidence of asthma. Obesity, by means of inflammatory mechanism or changes in lifestyle can trigger asthmatics symptoms in susceptible individuals.

RESUMO

Obesity is a disorder of body weight regulatory systems characterized by an accumulation of excess body fat. World Heath Organization recommended that 66% of deaths now occur in developing countries and recognizes obesity as a leading risk factor. Obesity is associated with chronic, low grade, systemic inflammation. The inflammatory state plays a causal role in the development of insulin resistance, type 2 diabetes and the metabolic syndrome. This study will design to evaluate the relation between obesity with fasting blood sugar (FBS). This descriptive type of cross sectional study had been performed to investigate the relationship between obesity with serum fasting glucose, of 100 obese and 100 normal weight persons from both sexes, aged between 25 to 60 years will be selected from Mymensingh Medical College, Mymensingh, Bangladesh and locality from July 2014 to January 2016. Data are collected through a simple questionnaire after informed consent taken. The result was calculated and analyzed by using SPSS (statistical package for social science, version 11.5). Statistical significance of difference between two groups was evaluated by unpaired Student's 't' test. Data were expressed as Mean±SE. P value less than 0.05 was taken as the level of significance. Anthropometric measurements such as height and weight were taken in meter and kilogram respectively. Pulse, systolic and diastolic blood pressure was measured by aneroid sphygmomanometer (ALPK2, Japan), laboratory analysis of serum fasting glucose will be estimated by GOD-PAP Method. In this study we found that fasting serum glucose is significantly increased in both male and female obese persons 4.07±0.79mmol/l & 5.58±0.64mmol/l respectively. In obese the values of FBS indicate the subjects are prone to develop cardiovascular & metabolic diseases. That has high morbidity and mortality. Therefore, by this study we recommended that routine estimation of fasting blood sugar is important for prevention of complication related to obesity for leading a healthy life.

RESUMO

In this cross sectional study peak expiratory flow rate (PEFR) were estimated in pregnant women during the first trimester of pregnancy and in third trimester of pregnancy, to observe the alteration in airflow rate during pregnancy. This cross sectional study carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years without any recent history of respiratory diseases were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group. Study group was further subdivided into 100 pregnant women in first trimester and 100 pregnant women in third trimester of pregnancy. The PEFR was estimated by using mini version of Wrights peak flow meter. PEFR was measured during 1st and 3rd trimester of pregnant women and in non pregnant women. In this study, the PEFR significantly decreased both in first and third trimester of pregnancy than that of non pregnant women. Again the PEFR was significantly decreased in 3rd trimester of pregnancy than that of 1st trimester of pregnant women. It may be concluded that PEFR were significantly decreased in pregnancy, most likely due to the mechanical effects of progressively increased size of uterus that progressively decreases lung volumes and capacities.

RESUMO

A 25 years married women having one child delivered vaginaly presented in the department of Obs & Gynae, Bangabandhu Sheikh Mujib Medical University, Bangladesh on April 2013 with pelvic pain and discomfort. No history of previous pelvic trauma was present. Patient examination showed a isolated mass in the right lower abdomen, right adnexa, extending to the pelvic wall upto lower end of ureter. Tumor markers were within normal limit. Intravenous pyelogram (IVP) showed mild right hydroureter and hydronephrosis with obstruction at the lower end of ureter. She was diagnosed as a case of adnexal mass with mild hydroureter & mild hydronephrosis and it was decided to operate on the patient. The surgical approach was transabdominal. On laparotomy a pseudocystic lesion 12×10cm in size was found over the right paracolic gutter and extending down into the pelvis involving the right parametrium. No abnormality was found in the uterus or tubes. The histological examination revealed a desmoid tumor of the pelvis. The patient's recovery was uneventful.

RESUMO

In the present study serum glucose were estimated in pregnant women during the first trimester of pregnancy and third trimester of pregnancy to observe the frequency of hyperglycemia during pregnancy and to assess the incidence of gestational diabetes mellitus. This study was a cross sectional study, carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group. Study group was further divided into 100 pregnant women in first trimester of pregnancy and 100 pregnant women in third trimester of pregnancy. Diagnosed case of type I and type II diabetes, hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug users, regular steroid users were excluded from this study. Serum glucose was evaluated by the glucose-oxidase principle by GOD-PAP method in women with 1st trimester of pregnancy, 3rd trimester of pregnancy and in non pregnant women. Statistical analysis of data was done by unpaired student's t test. The results showed that the serum glucose levels increased significantly in third trimester and the value is not significant in first trimester. The increasing frequency of serum glucose level in third trimester may predispose the women to hyperglycemia of pregnancy or gestational diabetes mellitus.

RESUMO

Asthma is a chronic inflammatory disorder of the airways, in which many cells and cellular elements play a role. Asthma is one of the most common diseases globally and currently affects 300 million people. The epidemic rise in anemia, asthma, and related allergic disease is a common major public health problem worldwide. Asthma and anemia associated with acute infections occur both in children and adults. This descriptive type of cross sectional study was done to find out the levels of hemoglobin concentration in adult asthmatic patients and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and 50 (fifty) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh, Bangladesh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. Hemoglobin concentration was estimated by Cyanmethemoglobin method. For statistical analysis unpaired student's 't' test was used. Mean hemoglobin concentration was significantly decreased in study group in comparison to control group and the result was statistically significant (p<0.001). The study findings showed a high prevalence of anemia among asthmatic patients than non asthmatic healthy persons.

RESUMO

Body mass index is an inexpensive and easy method of screening for weight categories that may lead to health problems. Increased BMI in overweight and obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between increasing BMI and glycemic control of body through measuring glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2011 to June 2012 on 180 equally divided male and female persons between the age of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Glycosylated hemoglobin was estimated by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean (±SE) and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. There was no significant difference of glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group (r=0.255, 0.37 and 0.39 in control, overweight and obese respectively). The observed positive correlation between BMI and glycosylated hemoglobin emphasizes the maintenance of normal BMI to prevent early onset of type 2 diabetes mellitus. Health education activities highlighting the danger of becoming overweight and obese should be undertaken.

RESUMO

Pregnancy is a great stressful physiological condition in women during their reproductive period. During pregnancy several hemodynamic, biochemical and hematological modifications occur as a part of the physiological adaptation of the body. Changes in blood pressure occur in third trimester of pregnancy, which may be associated with increased maternal and infant mortality and morbidity. This cross-sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, from July 2013 to June 2014. Study subjects were selected by following purposive sampling procedure and the protocol of this study was approved by Institutional Ethics Committee (IEC) of Mymensingh. This study enrolled 100 pregnant women of third trimester of pregnancy and 100 aged matched non-pregnant women from Mymensingh district. Mean systolic blood pressure in study group were 124.8±14.51 mm of Hg and in control group were 106.50±10.67 mm of Hg, which was statistically increased. Diastolic blood pressure in study group was 83.00±13.37 mm of Hg and in control group 71.05±7.12 mm of Hg, which was also statistically significant. The changes in blood pressure in third trimester of pregnancy is the major concern of developing the risk of pre-eclampsia & eclampsia, and increased prevalence of IUGR, pre-maturity and perinatal mortality. This study reveals significant changes of blood pressure during third trimester of pregnancy.

RESUMO

Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (p<0.0001). The examinations and biochemical investigations revealed that high BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

RESUMO

Various hormones can cause marked changes in pregnant woman's appearance. Decreased level of serum albumin occurs in third trimester of pregnancy, which may be associated with increased maternal and infant mortality and morbidity. So, this study was carried out to evaluate and assess the level of serum albumin in third trimester of pregnancy. This cross-sectional study was carried out in the Department of Physiology Mymensingh Medical College, Mymensingh. This study enrolled 100 pregnant women of third trimester of pregnancy and 100 aged matched non-pregnant women from Mymensingh district. In this study serum albumin level in study group were 33.41 ± 4.62gm/l and in control group were 37.09 ± 4.21 gm/l, which was statistically decreased. The lower level of serum albumin in third trimester of pregnancy is the major concern of development of physiological edema during pregnancy and may be associated with pre-eclampsia.

RESUMO

Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value <0.001) for obese group of BMI. There was no significant difference of glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive correlation between BMI with fasting serum glucose and glycosylated hemoglobin emphasizes the importance of maintenance of normal BMI to prevent early onset of type 2 diabetes mellitus.

RESUMO

Human leukocyte antigen B27 (HLA-B27), a class I molecules of the major histocompatibility complex has a strong disease association with different types of spondarthropathies (SpA). The strength of this disease association varies markedly among racial and ethnic populations. The present study aimed to identify the HLA-B27 antigen frequencies among suspected SpA patients as well as healthy Bangladeshi individuals. The frequency of HLA-B27 was determined in 1500 patients and 1000 healthy subjects attending the Bangabandhu Sheikh Mujib Medical University (BSMMU). HLA-B 27 typing was done by microlymphocytotoxicity test using commercial kit. A total of 738 (49.2%) suspected SpA patients and 107 (10.7%) healthy subjects tested positive for HLA-B27 antigen with higher frequency among younger age groups (54.9%, 52.4% and 56.2% in 0-14 years, 15-24 years and 25-34 years of age respectively). The male female positivity was almost same (11.4% and 9.6%) among control group, but in patient group it was 53.0% and 41.2% respectively. The findings of this hospital based study showed a high frequency of HLA-B27 among suspected SpA patients with male preponderance which is comparable with neighboring countries.

RESUMO

Gamma interferon (IFN-γ) plays an important role in the immune response to live measles virus vaccination. To study the immune response to measles vaccination, IFN-γ level was estimated in 30 children. Of these, 24 children vaccinated with a single dose of measles vaccine at nine months of age and 06 children vaccinated with a second dose during the Measles Catch-up Immunization campaign. Measles vaccine strain was cultured in Vero cell line and the Tissue Culture Infective Dose (TCID)50 was used as standard live virus. Peripheral blood Mononuclear cells (PBMCs) was separated by Ficoll-Hypaque density gradient centrifugation and stimulated with measles virus antigens and mitogens (lectin), cultured in CO2 and iFN-γ level was measured from culture supernatant by ELISA. On stimulation with measles antigen and lectin respectively, IFN-γ level was highest (105 pg/ml and 226.54 pg/ml) in the 109-120 months age group while it was lowest (12.97 ± 8.16 pg/ml and 13.16 ± 8.0 pg/ml) in the 61-72 months age group. No significant difference was observed in IFN-γ level after stimulation with either measles antigen or lectin among well-nourished (p < 0.8) and mal-nourished (p < 0.7) children suggesting that nutritional status did not have any effect on IFN-γ level. However, IFN-γ level was higher in children who received two dose of measles vaccine than those who received a single dose (p < 0.001).

RESUMO

Now a days, chronic obstructive pulmonary disease (COPD) is a global health problem. This study was done to evaluate the changes of body mass index (BMI) and blood pressure (BP) 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, Mymensingh between the periods from July 2018 to June 2019. Total 160 male subjects, age ranged from 30-70 years was included in this study. Among them, in study group (Group II) eighty (80) male COPD subjects and eighty (80) age matched male healthy subjects were taken as control group (Group I). BMI was calculated as weight in kilogram divided by the height in meter square. Blood pressure was measured with an aneroid sphygmomanometer. 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 BMI of Group I and Group II were 24.52±1.35kg/m² and 21.22±1.30kg/m² respectively. The mean±SD of systolic blood pressure of Group I and Group II were 118.75±7.73 mm of Hg and 134.56±15.24 mm of Hg respectively. The mean±SD diastolic blood pressure of Group I and Group II were 77.63±6.70 mm of Hg and 84.69±8.05 mm of Hg respectively. The mean±SD of BMI was significantly lower in study group and the mean±SD of systolic and diastolic blood pressure was significantly higher in study group than control group. Low BMI and hypertension in subjects with COPD are associated with a high risk of exacerbations and mortality. So assessment of this parameter is important for prevention of complication related to COPD for leading a healthy life.

RESUMO

Sedentary behavior has significant deleterious effects on human health. Sedentary behaviors associated with cardiovascular and metabolic disorders by decreasing lipoprotein lipase activities, impaired lipid and carbohydrate metabolism. This cross sectional study was done to see the association between fasting serum glucose and serum total cholesterol in sedentary male. This study was conducted in the Department of Physiology, Mymensingh Medical College, Bangladesh from Octy 2021 to June 2022. A total number of 100 subjects were included in this study. Among them, fifty (50) sedentary males were taken as study group (Group II) and fifty (50) active males were taken as control group (Group I). Age of both control and study group ranged from 25-60 years. Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired students' 't' test & Pearson's correlation coefficient test. Both of these biochemical parameters showed statistically significant difference in study group. The mean±SD of fasting serum glucose of control group (Group I) and study group (Group II) were 4.45±0.51 mmol/L and 5.91±0.60 mmol/L; and the mean±SD of serum total cholesterol level of control group (Group I) and study group (Group II) were 176.14±27.16 mg/dl and 252.58±18.97 mg/dl respectively. Fasting serum glucose and serum total cholesterol shows positive correlation in study group in comparison to control group. From this finding it can be concluded that there was significant correlation of fasting serum glucose and serum total cholesterol in sedentary males.

RESUMO

Oral contraceptives pills (OCPs) are one of the most commonly used methods of birth control by women worldwide. 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 an estrogen and a progesteron. 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 find out the association of serum total cholesterol and blood pressure in combined oral contraceptive pill users. This cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Bangladesh between the periods from July 2021 to June 2022. A total number of 120 reproductive aged women, age ranged from 15-55 years were included in this study. They were divided into two group, sixty (60) combined oral contraceptive pill users 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. Pearson 'r' value of systolic blood pressure and diastolic blood pressure are 0.582 and 0.416 respectively indicates positive correlation with serum total cholesterol. Correlation is statistically highly significant (p<0.001). Blood pressure and serum total cholesterol were positively connected in study group in comparison to control group respectively. So from this study, it can be concluded that there is a significant association between serum total cholesterol and blood pressure with oral contraceptives.
