This research aims to examines the influence of age on masculinization of Clarias gariepinus larvae immersed by methyl testosterone (MT) natural hormone. This research used 270 catfish larvae divided into 3 groups of age those are 5, 10, and 20 days. The research implemented complete random design (CRD). Immersion was performed using methyl testosterone hormone at the dose of 0.25 g/L for 20 hours. Observation of fish was done after 60 day-old fish. Data obtained was analyzed using one-way analysis of variance The average percentages of male-sex catfish after immersing in natural MT on group I, II, and III were 97.67, 91.07, and 86.67%, respectively. The results showed that the age of the larvae did not affect significantly (P>0.05) on the percentage of male sex of Clarias gariepinus. The average percentage of male sex in 5 days age group was higher than 10 and 20 days age group. In conclusion, the masculinization of Clarias gariepinus larva immersed by MT natural hormone is not influenced by age of fish before dipping.

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.

Abstract How the self perceives reality is a traditional topic of research across several disciplines. I examine the perceived self on Facebook, as a case-study of self-knowledge on „classical” social media. Following Blascovich & Bailenson (2011), I consider the distinction between the real and the virtual as relative. Perceptual self-knowledge, filtered through social media, requires rethinking the perceived self in terms of social reality (Neisser, 1993). This claim dovetails Jenkins’s (2013) notion of the self as an active participant in consumption. I argue that the perceived self in social media could be conceived in terms of how it would like to be perceived and appraised by its virtual audience. Using Neisser’s (1993) typology of self-knowledge and Castañeda’s (1983) theory of I-guises, I analyse seven samples from Anglo-American and Bulgarian Facebook sites and show that the perceived self produces itself online as a captivating presence with a credible story. My samples are taken from FB community pages with negligible cultural differences across an online teenage/twens (twixter) age group. I then discuss some problematic aspects of the perceived self online, as well as recent critiques of technoconsumerism.

Hematological parameters have been recognized as valuable tools for monitoring fish health. The aim of the present study was to obtain a basic knowledge of the hematological responses of different groups of fresh water teleosts during acclimation period. Haematological analysis was carried out in three different groups of teleosts namely Group I: Heteropneustes fossilis and Clarias gariepinus (Siluriformes), Group II: Anabas testudineus and Channa striatus (Perciformes), Group III: Labeo rohita and Cyprinus carpio (Cypriniformes). In all groups of teleosts, RBC and Hb were significantly (p<0.05) decreased after 7 days of captivity in response to stress factors raised in capture, handling and sampling procedure. WBC was found to be significantly (p<0.05) increased in group I (Siluriformes), group II (Perciformes) and group III (Cypriniformes) of teleosts after 7 days of captivity due to enhanced production of leucocytes in the hematopoietic tissue of the kidney and the spleen. RBC count and WBC count were found to be higher in H. fossilis and C. gariepinus than other groups of teleosts due to their active predacious nature. Hb values were high in 2nd group (Perciformes) consisting of A. testudineus and C. striatus by virtue of their possessions of accessory respiratory organs. PCV, MCV and MCHC were significantly (p<0.05) increased in three groups of teleosts during acclimation and values were high in second group of consisting of A. testudineus and C. striatus. MCH was higher in 3rd group of fishes consisting of L. rohita and C. carpio.

ABSTRACT Aim To estimate the prevalence of ocular morbidity among primary school children in Delhi area. Materials and methods This was a descriptive cross-sectional study. The study was conducted among primary school children of age group 5–12 years in Delhi area. A total of 1,100 school-going children were evaluated. After questionnaire administration, visual acuity, examination of anterior and posterior segment structures of the eyes of the children were carried out. For the statistical analysis, children were divided into three groups: group I (5–7 years), group II (8–10 years), and group III ((<12 years) based on age. Results A total of 1,100 school children (625 boys and 475 girls) participated in the study. A total of 282 (25.6%) children had visual impairment and 315 (28.6%) children had ocular morbidities. The common ocular morbidities identified were refractive error 25.6%, color vision defective 0.9%, convergence defect 1.8%, and squint 0.2%. The older age group (8–10 years) had a higher prevalence of refractive error, especially myopia, compared to the younger age group (5–7 years) and group ((<12 years) (p < 0.001). Conclusion A high prevalence of ocular morbidity among school children of age group 8–10 years was observed. Refractive errors were the most common ocular disorders. This study emphasized that a simple school visual screening program is effective for the early detection of ocular problems. How to cite this article Reddy S, Velamakanni GS, Mogra S.

Background: The objective was to quantify joint laxity in healthy volunteers by measuring the passive axial rotation of the trapeziometacarpal joint using the axial rotation test. Methods: Eighty volunteers (34 men and 46 women) were subjected to the axial rotation shear test and the degree of total rotational motion (TRM) was assessed. Volunteers were divided into Group I with a range of 18–50 years old and Group II for 51 years and older. Statistical analysis was performed. Results: The average TRM in Group I was 32.3 mm for women, and 27.4 mm, for men (p = 0.04). The average TRM in women of Groups I and II, was 32.3 and 21.6 mm respectively, (p < 0.001). The average TRM in men of Groups I and II, was 27.4 and 19.4 mm (p < 0.001). In Group II the average TRM of women was 21.6 mm, and for men was 19.4 mm, which was not significantly different. Conclusions: Young women have greater degree of rotational laxity in the TM joint compared to men of the same age group and to older women. The axial rotation test can quantify the degree of rotational laxity of the TM joint.

AS THIS is the first general meeting of the Academy since the establishment of a surgical section, it would seem fitting to comment on our hopes for this venture. The last few decades have seen great advances in all fields of medicine. Among the most widely known, perhaps, are insulin, antibiotics, chemotherapy, water balance, vitamin and hormone therapy and other laboratory discoveries. I want, however, to call your attention to some of the advances which have been made in the field of pediatric surgery and to remind you that although these have been aided by laboratory achievements they would have been impossible without the cooperation of the pediatrician. Please recall that roughly 30 years ago atresia of the bile ducts carried a mortality of 100%. Intestinal obstruction due to midgut volvulus had an equally high mortality. Congenital diaphragmatic hernia—other than those through the esophageal hiatus—had an estimated 90% mortality. The recovery of a patient with intestinal atresia was indeed a rare incident. The mortality from intussusception, and even from pyloric stenosis, was nearly 60%. Today the mortality in these and other conditions has been reduced by from 25% to 75%, and in some conditions to nearly zero. This striking lowering of mortality has been brought about largely by men, both medical and surgical, who devote their energies to the care of infants and children. It seems, therefore, particularly opportune and appropriate that these pediatricians and pediatric surgeons should join together in a concerted effort to advance the care of this age group. I, for one, am sufficiently optimistic to believe that greater advances will be made in the decades to come if we all work together and with one goal in mind; namely, the improvement of the lot of the afflicted child. The establishment of a surgical section in this Academy certainly should help the pediatrician, the pediatric surgeon and last, but far from least, sick children.

To test the hypothesis that vasodilatory prostaglandins buffer the renal vasoconstrictor effects of endothelin-1 (ET-1) early in life, renal haemodynamic responses to ET-1 were measured in 2 groups of conscious, chronically instrumented lambs at 1–2 weeks of age (group I, n = 11) and 6 weeks of age (group II, n = 10). Lambs were pretreated with vehicle or 1 mg·kg–1 indomethacin, a nonselective cyclooxygenase inhibitor, and renal haemodynamic effects were measured continuously for 1 min before (control) and 5 min after intra-arterial injection of 250 ng·kg–1 ET-1. In group II lambs, there was a marked decrease in renal blood flow (RBF) and renal vascular conductance (RVC) elicited by ET-1 administration, as we have previously described. This response was not altered by vehicle or indomethacin pretreatment. In group I lambs, there was an initial increase but no decrease in RBF and RVC elicited by ET-1 administration, as we have previously described, and this response was also not altered by either vehicle or indomethacin. These results suggest that endogenously produced prostaglandins do not appear to modulate the renal haemodynamic effects of ET-1 in conscious lambs during postnatal maturation.
