These skills can be influenced by factors like age, gender, built of an individual and handedness. It’s a known fact that the dominant hand has more dexterity; nevertheless, proficiency of the non-dominant hand can be improved with repetition of tasks and procedures. The aim of the present study was to examine the influence of biofeedback mechanism on psychomotor skills performance and gender variation in their activity. Eighty participants aged between 20-30 years were recruited after taking the informed consent. All the subjects performed number countdown test and 100 pin dexterity test. Tests were done by fixing the subject’s heart beats instead of stipulated time which was picked up by finger Pulse plethysmography using optocoupler principle. The results were compared between the males and age-matched female participants. The pin dexterity scores with a right and left hands in males (57.2±8.1, 42.16±7.3) were significantly higher than females (48.41±8.4, 37.58±6.8) (p = 0.001 and p = 0.01). There was no significant difference in number countdown test scores. The results suggest that males handle a skilled performance better than females. This is perhaps males were less anxious as the task was designed in such way that it has to be completed by counting down the heart beats. In that way, the males got more time duration as the heart rate did not shoot up when the task was assigned.</p> Chintala Kiran Kumar, A. V. Siva Kumar, Pullaganti Madhurima, K. N.

This study was done to find out whether there are any changes in central arterial parameters during different phases of menstrual cycle. Thirty female&nbsp; subjects&nbsp; in the&nbsp; age&nbsp; group&nbsp; of&nbsp; 18-22&nbsp; years&nbsp; with&nbsp; normal,&nbsp; regular menstrual&nbsp; cycles&nbsp; participated in this prospective observational study at our teaching hospital. Anthropometric parameters were recorded.&nbsp; Blood pressure in all 4 limbs was recorded using cardiovascular risk analyzer-Periscope™ on Day 3<sup>rd</sup> to 5<sup>th</sup> (follicular phase), Day 12<sup>th</sup> to 14<sup>th</sup> (ovulation phase), Day 22<sup>nd</sup> to 24<sup>th</sup> (luteal phase) of their menstrual cycle. We collected blood samples during these three phases for estimation of estradiol and progesterone by ELISA technique. Analysis of variance and correlation statistics were done using SPSS 17.0 statistical software. No significant statistical changes were observed in systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure, aortic systolic pressure, aortic diastolic pressure, aortic augmentation pressure, aortic index and pulse wave velocity during the three recorded phases of the menstrual cycle. There are many studies which correlate changes in peripheral artery blood pressure with different phases of menstrual cycle. But there is scarcity in data available which correlates central arterial pressures and arterial stiffness with natural hormonal variations in different phases of menstrual cycle. However, our results show that although there are subtle changes in blood pressure parameters along with estrogen and progesterone levels throughout the menstrual cycle, yet these were not statistically significant.</p> Nudrat Kahkashan, Mehnaaz Sameera Arifuddin, Mohammed Abdul Hannan Hazari, Safia Sultana, Farah Fatima, Syyeda Anees ##submission.copyrightStatement## Wed, 28 Nov 2018 00:00:00 -0500 Hemorheology: Capturing the fluid dynamics of blood Mohammed Abdul Hannan Hazari ##submission.copyrightStatement## Wed, 28 Nov 2018 00:00:00 -0500 A comparative study on ABO blood group and fertility hormones in infertile women in Calabar, Southern Nigeria <p>Infertility, a disorder of the reproductive system, is commonly linked to hormonal, pituitary, cervical, uterine, immunological or psychological factors. Besides these factors, it can also be idiopathic or unexplained. Hence, there is a need for more research to unravel the causes of the unexplained infertility. This work aimed at finding out whether there is any relationship between ABO blood group system and female infertility. The study design was cross-sectional. Three hundred women between 18 and 40 years attending fertility clinic at the University of Calabar Teaching Hospital, Calabar between 2011 and 2012 were recruited for this study. Serum progesterone, prolactin, follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol were determined using Enzyme linked immunosorbent assay (ELISA) while ABO blood grouping was determined using the tube method. Statistical analysis was done using SPSS version 18. The confidence level was set at 95% where p-value less than 0.05 was considered statistically significant. The mean age of the women was 30.65 ± 5.47 years and the percentage distributions of the blood groups among the women were as follows: 24% A, 12% B, 4% AB and 60% O. The mean FSH levels of blood groups A and O individuals were significantly higher (p&lt;0.05) than that of groups B. However, there was no significant difference (p&gt;0.05) in the mean levels of progesterone, prolactin, LH and estradiol in the respective groups. From this study, 38% of the population had increased levels of progesterone, 58% and 18.7% had elevated prolactin and FSH levels respectively while 11.33% and 43.3% had reduced levels of LH and estradiol levels respectively. Though, there was high prevalence of hyperprolactinemia observed in this study, there was no strong association between ABO blood group and female infertility but, the increased FSH levels observed in blood groups A and O may be a potential link between blood group and infertility and therefore may be beneficial for further study.</p> Uwem Okon Akpan, Iya Eze Bassey, Nnenna Nkiruka Nwatu, Sunday Jeremiah Offor ##submission.copyrightStatement## Sun, 01 Jul 2018 02:17:33 -0400 Nanophysiology: Real-time phenomenal perspective in biology Mohammed Abdul Hannan Hazari ##submission.copyrightStatement## Sun, 01 Jul 2018 01:45:58 -0400 Vitamin D status in medical students and risk factor analysis <p>Vitamin D is finding increasing health implications beyond calcium homeostasis. Vitamin D deficiency is prevalent globally including India. Many asymptomatic individuals have hypovitaminosis implicating the need for intervention. The present study aimed at evaluating vitamin D levels among healthy medical students from southern India and its association with well-known risk factors. Hundred apparently healthy medical students between the age group of 18-25 years were recruited based on defined inclusion and exclusion criteria. A questionnaire form with details of sun exposure, tanning, milk intake, general health and drug history were obtained. Vitamin D levels were assessed by chemiluminescent immunoassay (CLIA). Vitamin D values were considered normal for 30-60 ng/ml, deficient for &lt;20 ng/ml and insufficient for levels between 21-29 ng/ml. Majority of the students (89%) had deficient 25-hydroxyvitamin D levels while 8% of the student had insufficient and 3% of the students had sufficient 25-hydroxyvitamin D levels. The mean 25-hydroxyvitamin D level was 14.01±6.20 ng/ml, median level was 12.95 ng/ml and ranged between 5.15 to 43.01 ng/ml. No statistically significant association was noted with sex, BMI, sun exposure, dietary intake or serum calcium levels. To conclude, vitamin D deficiency is highly prevalent in asymptomatic medical students and showed lack of relationship with the well-defined risk factors in literature prompting to look for newer risk factors in this country.</p> Vidya Sunil Joshi, Rahul Mandal ##submission.copyrightStatement## Sat, 31 Mar 2018 06:12:23 -0400 Immediate and delayed effect of Ramadan fasting on spirometry parameters <p>Fasting in the month of Ramadan is an obligatory duty for muslims. Researchers have investigated health benefits of fasting and reported conflicting results. The purpose of this study was to determine the immediate and delayed effects of Ramadan fasting on spirometric parameters. 50 apparently healthy young adults aged between 17-27 years, belonging to both genders who fast during the month of Ramadan were enrolled for the study. Spirometric recordings were done at three different time points. First: 5-10 days before the start of Ramadan (Pre-Ramadan); second: within 10 days of the beginning of Ramadan fasting (Ramadan); third: within 7 days of the end of Ramadan (Post-Ramadan). There were no statistically significant differences between the three phases with respect to tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR) and forced expiratory flow 25% to 75% (FEF25-27). To conclude, Ramadan fasting does not have any significant effect on pulmonary function tests as assessed by spirometry. Hence, the diagnosis and prognosis of a respiratory disorder made on spirometry findings are reliable and need no error correction if an individual is fasting.</p> Adiba Sayeed, Mohammed Abdul Hannan Hazari, Mehnaaz Sameera Arifuddin ##submission.copyrightStatement## Sat, 31 Mar 2018 06:01:09 -0400 Menarcheal age of blind girls <p>Menarche is a developmental milestone. Age at which menarche is attained is highly variable and highly sensitive to a variety of internal and external forces like climatic conditions, physical and mental factors, nutrition and socio-economic status. Exposure to light and other visual cues may influence the pubertal changes. Menarcheal age (MA) of 110 blind girls was compared to that of 102 normal girls of same age group and of same area of residence. An advancement of 9 months in MA was seen in blind girls. Influence of light and other factors on menarche is discussed.</p> Kalanghot Padmanabhan Skandhan, Spandana Reddy, Amita Pandya, Sumangala Balakrishnan, Dayani Osuki, Jaya Vasudevan ##submission.copyrightStatement## Sat, 31 Mar 2018 05:48:02 -0400 Target with-in target Mohammed Abdul Hannan Hazari ##submission.copyrightStatement## Sat, 31 Mar 2018 00:00:00 -0400
