A study was conducted to elucidate the topographic location and morphometry of the spleen in 30 Surti goat foetuses at different stages of their development ranging from 44 to 144 days (4.0 to 41.0 cm CRL). On the basis of CR length, the foetuses were divided into three age groups viz., group-I (4.0 to 11.6 cm CRL), group-II (12.2 to 26.8 cm CRL) and group-III (27.2 to 41.0 cm CRL). Special attempt has been made to fit prediction equation (stepwise regression) for estimation of approximate age of Surti goat foetuses by using splenic biometrics. The developing spleen was observed at the age of 44 days (4.0 cm CRL) in abdominal cavity close to the stomach. The shape of spleen was roughly quadrilateral in all age groups. The various spleen measurements viz., length, width, thickness, volume and weight increases in dimensions during different stages of development and all the changes were highly significant (P less than 0.01). The mean relative weight of spleen was maximum (0.15%) in group-III. Among splenic parameters, the length of spleen was found most important variable; which could be used for estimation of age using stepwise regression (R2 = 0.97) model in Surti goat foetuses.

A study was conducted on the adrenal gland of 20 Gohilwadi goats (Capra hircus), age ranging from day old to adult. Animals were divided in three age groups, viz., group-I (day old to 1 month), group-II (1 to 6 months) and group-III (above 6 months). The different gross and biometric parameters, viz., weight, length, width and thickness of both left and right adrenal gland were recorded. The left adrenal gland was roughly oval elongated and right was roughly triangular in shape in all the age groups. Different biometric parameters of adrenal gland increased significantly (P less than 0.05) from group I to group III. There was no significant difference (P>0.05) in various gross and biometric observations between left and right adrenal gland within the same group.

This study evaluated age-related changes in the gross morphology and morphometry of the testis and epididymis of the African Greater Cane Rat (AGCR). Twenty pathogen-free cane rats used for this study were randomly divided into 4 groups; Group I - prepubertal (≤4 months), Group II - pubertal (>4≤12 months), Group III - adult (>12≤30 months), and Group IV - aged (>30 months) of 5 animals each. On day 8th of acclimatization, testis and epididymis were harvested from sedated cane rat, described grossly and standard morphometric parameters (length, width, circumference, weight, and relative weight) determined. Gross morphological observations in the testes of all the different age categories showed similar characteristically cream to milky-white coloration and ellipsoidal shape. The epididymis in the different AGCR group uniquely presents the same inverted S-shaped outline, loose attachment to the testis, and less distinct division into caput, corpus, and cauda segments. Testicular and epididymal morphometric parameters were significantly reduced in the prepubertal cane rat relative to other groups. The parameters consistently displayed an age-dependent increment with the advancing age of the animal. In conclusion, this study has shown that both testicular and epididymal gross morphometrics increase with age advancement and perhaps might be linked to the varying functional reproductive status of the different age groups of the African greater cane rat.

Endurance exercise performance declines with age; however, there is little information on the mechanisms responsible, especially in women. We tested the hypothesis that this performance decline in women is associated with decreases in maximal O2 consumption (VO2max), blood lactate threshold (LT), and running economy (RE). We determined a 10-km race pace, VO2max, LT, and RE in 31 highly trained female runners aged 23–56 yr with similar relative (i.e., age-adjusted) competitive performances. Absolute 10-km race pace declined with age (r = -0.83). Both 10-km performance and age were correlated with VO2max (P < 0.05) and with the running velocity and O2 consumption at LT but not with RE. The runners then were divided into three age groups: group I (23–35 yr), group II (37–47 yr), and group III (49-56 yr). Stepwise regression analyses performed on subjects pooled from groups I and II and from groups II and III indicated that the majority (60%) of the variability in performance for runners aged 23–47 yr was explained by the running velocity at which LT occurred, whereas VO2max explained the majority (74%) of the variability for the runners aged 37–56 yr. We conclude that decreases in VO2max and running velocity at LT are the two physiological phenomena most closely associated with declines in 10-km performance with age in highly trained female runners. However, the contributions of these two mechanisms to the declines in performance are not uniform with advancing age.

AbstractThis study was aimed to evaluate different management modalities for peripheral vascular trauma in children, with the aid of the Mangled Extremity Severity Score (MESS). A single-center retrospective analysis took place between 2010 and 2017 at University Hospitals, having emergencies and critical care centers. Different types of vascular repair were adopted by skillful vascular experts and highly trained pediatric surgeons. Patients were divided into three different age groups. Group I included those children between 5 and 10 years; group II involved pediatrics between 11 and 15 years; while children between 16 and 21 years participated in group III. We recruited 183 children with peripheral vascular injuries. They were 87% males and 13% females, with the mean age of 14.72 ± 04. Arteriorrhaphy was performed in 32%; end-to-end anastomosis and natural vein graft were adopted in 40.5 and 49%, respectively. On the other hand, 10.5% underwent bypass surgery. The age groups I and II are highly susceptible to penetrating trauma (p = 0.001), while patients with an extreme age (i.e., group III) are more susceptible to blunt injury (p = 0.001). The MESS has a significant correlation to both age groups I and II (p = 0.001). Vein patch angioplasty and end-to-end primary repair should be adopted as the main treatment options for the repair of extremity vascular injuries in children. Moreover, other treatment modalities, such as repair with autologous vein graft/bypass surgery, may be adopted whenever possible. They are cost-effective, reliable, and simple techniques with fewer postoperative complication, especially in poor/limited resources.

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.

Objective. To investigate the mortality rate, comorbidity prevalence, and etiology of community-acquired pneumonia (CAP) in elderly patient population. Materials and Methods. Hospitalized elderly patients with CAP were distributed into the following age groups: 65–74 years (group I), 75–84 years (group II) and 85–94 years (group III). The patients’ medical records were used for determining comorbidities and mortality rate. In order to determine etiology of CAP, sputum or BAL samples were collected. A total of 171 isolates were identified using MALDI-TOF MS. Results. The mortality rates were 27.1%, 31.5% and 45.7% in age groups I, II, III, respectively. The most common concomitant diseases in all age groups were arterial hypertension (47.4%, 54.6%, and 62.8% for groups I, II, and III, respectively), chronic heart failure (45.7%, 50.9%, and 60.0%, respectively), and coronary heart disease (15.2%, 25.9%, and 24.3%, respectively). The most frequently isolated bacteria by age group were the following: group I – non-fermenting Gram-negative bacteria (NFGNB) (7.4%), Enterobacterales (6.6%), S. aureus (6.6%); group II – Enterobacterales (13.9%), S. aureus (5.6%), Enterococcus spp. (5.6%), NFGNB (2.8%); group III – NFGNB (15.4%), S. aureus (7.7%), Enterococcus spp. (7.7%), Enerobacterales (7.7%). Conclusions. The mortality rates in elderly patients with CAP were high and varied from 27.1% in 65–74 years old patients to 45.7% in 85–94 years old patients. The most common comorbidities in all age groups were arterial hypertension (up to 62.8%), chronic heart failure (up to 60%), and coronary heart disease (up to 25.9%). The main pathogens causing CAP in elderly patient population were Enterobacterales and non-fermenting Gram-negative bacteria.

The objective of this study was to investigate the development of rumen mucosa and the level of plasma IGF-1 in calves induced by different amounts and types of milk replacers and solid diet. Forty-five male Holsteincalves 7 days of age were assigned to three groups: group I milk free replacer, late weaned; group II milk free replacer, early weaned, and group III milk replacer, early weaned. All animals received additional concentrate, water and maize silage were offered ad libitum. In each group, three calves were slaughtered at 41 days of age. The concentration of ruminal total SCFA and the molar proportion of butyrate did not differ between the groups, but the molar proportion of acetate was lower (P = 0.01) and the proportion of propionate was higher (P = 0.02) in early weaned calves. Compared to the late weaned calves (group I) the length, width and surface of the papillae of atrium ruminis, the length and width of the papillae of ventral ruminal sac and the length of the papillae of ventral blind sac were greater (P &lt; 0.05) in the early weaned calves fed low amounts of milk and high amounts of concentrate (group III). Furthermore, there was a tendency of plasma IGF-1 concentration to be increased (P&nbsp;= 0.1) in early weaned calves. The plasma levels of glucose and insulin were decreased (P &lt; 0.01, and P = 0.03, respectively). Positive correlations existed between papillae length and plasma IGF-1 concentrations (P &lt; 0.10). Insulin and glucose concentrations were negatively correlated with parameters of papillae development (P &lt; 0.1). In conclusion, the development of rumen papillae was stimulated in calves consuming increased amounts of concentrate. The effect was not correlated with the molar proportion of butyrate, but with the molar propionate proportion in the rumen and with the plasma IGF-1 concentration

The present study was carried out on tongue measurements in Surti goat fetus to establish the relationship among various biometric measurements of the tongue and body in relation to prediction of fetal age. Total 39 apparently normal Surti goat fetuses were procured and categorized into three groups based on Crown-rump length. The body measurements like Crown-rump length, Curved Crown-rump length, height at withers and height at pin of fetuses were taken. The biometrical measurements of the tongue were recorded identically weight, length, width, thickness and circumference. Tongue biometry and body measurement’s association determined by simple linear correlation. Attempts were made for development of prediction equation for prediction of fetal age with tongue and body measurements. All the biometric measurements of tongue increase significantly (p£0.05) with advancement of age. Association among biometric measurements of the tongue and body expressed high degree of positive correlation. Predictability of regression equations is very high for prediction of fetal age. All biometric and body measurement’s correlations are highly significant (p£0.01).

The reproductive rate of brook trout populations from infertile Pennsylvania streams was determined. The standing crops for eight streams varied between 14 and 41 lb/acre. Trout in age-groups 0 through III were found to grow slowly with very few individuals reaching a total length of 6 inches.The seasonal development of ova was determined by measuring all ova larger than 0.2 mm from selected females. The maturing ova of most females of age-groups II and III increased in diameter from 0.9 mm in February to 1.0 mm in June, 1.75 mm in July, 2.5 mm in August, 3.0 mm in September, and 4.0 mm in October. Maturing females could be distinguished from immature females by late August or early September on the basis of ova diameters. The mean diameter of ripe ova from 67 females was 4.05 mm with a range between 3.37 and 5.01 mm for individual trout ranging from 4.6 to 8.6 inches total length.The relationship between the number of mature ova and the total length of the female for one population was described by a curvilinear regression (log Y = −0.5361 + 3.23 log X, where Y = number of eggs, and X = the total length of the fish) for brook trout between 3.6 inches (18 eggs) and 7.7 inches (213 eggs). Variation in this relationship existed among streams.Ova production was estimated as 9050 ova per acre for one population and 13,620 ova per acre for another. Age-group-I females contributed approximately 9% of this production; age-group-II females, 54%; and age-group-III females, 37%. An ecological life table was constructed for two populations comparing rates of survival, age-specific fecundity rates, and reproductive rates.
