Aspects of the reproductive strategy of African carp,Labeobarbus batesii, were investigated from May 2008 to October 2009 in the Mbô Floodplain of Cameroon. Samples were collected monthly from artisanal fishermen. The total length and total body mass of each specimen were measured to the nearest mm and 0.01 g, respectively. Sex was determined by macroscopic examination of the gonads after dissection. The sex ratio was female skewed (overall sex ratio: 1 : 1.42). Females reach sexual maturity at a larger size (213 mm) than the males (203 mm). The mean gonadosomatic index ranges from0.32±0.17% to1.91±1.15%, whereas the meanKfactor ranges from0.90±1.09to1.10±0.13. These two parameters are negatively correlated. The reproduction cycle begins in mid-September and ends in July of the next year, and they are reproductively quiescent for the rest of the year.Labeobarbus batesiiis a group-synchronous spawner with pulses of synchronised reproduction spread over a long period. The mean absolute, potential, and relative fecundities are2898±2837oocytes,1016±963oocytes, and9071±7184oocytes/kg, respectively. The fecundity is higher and positively correlated with the gonad mass than with body size. Its reproductive biology suggests thatL. batesiiis suitable for pond culture.

AbstractThe main purpose of the present study was to compare the reference metabolic equivalent (MET) value and observed resting oxygen uptake (VO2) for defining cardiorespiratory fitness (VO2max) and characterizing the energy cost of treadmill running. A heterogeneous cohort of 114 healthy men volunteered to participate. In Part 1 of the study, 114 men [mean±SD, age: 24±5 years; height: 177.1±7.9 cm; body mass: 75.0±10.0 kg] visited the laboratory twice for assessment of resting and maximal VO2 values to compare the reference MET value vs. observed resting VO2 and to investigate the association between resting VO2 and VO2max. In Part 2, 14 of the 114 men visited the laboratory once more to perform a 30-min bout of running at 8.0 km∙h−1/8.3 METs. The mean observed resting VO2 of 3.26 mL·kg−1·min−1 was lower than the reference MET value of 3.5 mL·kg−1·min−1 (P<0.001). Resting and maximal VO2 values relative to total body mass and fat-free mass were positively correlated (R=0.71 and 0.60, respectively; P<0.001). The maximal MET and energy cost of treadmill running were consequently underestimated when calculated using the reference MET value only for those with low VO2max (P=0.005 to P<0.001). In conclusion, the reference MET value considerably overestimated observed resting VO2 in men with low VO2max, resulting in underestimations of the maximal MET, exercise intensity prescription, and the energy cost of running.

In this research, we discussed bone density for women taking into consideration the method of research, we measure the total body mass of women in premenopausal and comparing it with postmenopausal, since the amount of the bone mineral content and bone mineral density, fat mass and lean mass.A cross sectional study conducted at DXA laboratory, Physiology Department, College of Medicine, University of Ninevah, Mosul-Iraq from Jan. 1 - Dec. 31, 2013. Since 174 healthy women recruited from reviewing of college medical academic center. They were divided into two groups: pre menopause group (n = 42) and post menopause group (n= 130). Detailed anthropometric data were gathered from study subjects. The mean age SD of pre-menopause group was (43.37 7.49) year while the mean age SD postmenopausal group (63.63 9.23) years .The T-score, Z-score, Bone Mineral Density (BMD), Bone Mineral Content (BMC), Fat Mass and Lean Mass were measured in the supine position by the use of DXA bone densitometer scanner type (STRATOS) from (DMS) group, France.Bone Mineral Content (BMC) was significantly lower in arm, rib, and thoracic spines. Bone Mineral Density (BMD) in arm, rib, leg and total were significantly low in postmenopausal women. Non-significant differences were noticed between both groups for lean mass. Postmenopausal women having more fat mass than pre menopause group. Both T-score and Z-score for pre menopause and post menopause groups were from class of osteopenia, but it was significantly lower in post menopause group (p-value =0.001, 0.008 respectively).Postmenopausal women were at higher risk of osteoporosis due to lowered Bone Mineral Density , T & Z scores.

SummaryIt has been reported that blood trombopoietin (TPO) levels can discriminate between thrombocytopenia due to increased platelet destruction and decreased platelet production. With our TPO ELISA and a glycocalicin ELISA we analysed a large group of patients in detail and could confirm and amplify the above notion in detail.TPO levels were determined in plasma from 178 clinically and serologically well-defined thrombocytopenic patients: 72 patients with idiopathic autoimmune thrombocytopenia (AITP), 29 patients with secondary AITP, 5 patients with amegakaryocytic thrombocytopenia and 72 patients who suffered from various diseases (46 in whom megakaryocyte deficiency was not and 26 in whom it was expected). In addition, we measured the level of glycocalicin as a marker of total body mass of platelets.In all patients with primary AITP and secondary AITP, TPO levels were within the normal range or in some (n = 7) cases only slightly increased. The level of glycocalicin was not significantly different from that of the controls (n = 95). The patients with amegakaryocytic thrombocytopenia had strongly elevated TPO levels and significantly decreased glycocalicin levels. Similarly, among the 72 thrombocytopenic patients with various disorders, elevated TPO levels were only found in patients in whom platelet production was depressed. The mean level of glycocalicin in these patients was decreased compared to that in controls and patients with AITP, but was not as low as in patients with amegakaryocytic thrombocytopenia.In conclusion, all patients with depressed platelet production had elevated levels of circulating TPO, whereas the TPO levels in patients with an immune-mediated thrombocytopenia were mostly within the normal range. Therefore, measurement of plasma TPO levels provides valuable diagnostic information for the analysis of thrombocytopenia in general.Moreover, treatment with TPO may be an option in AITP.

1. The kinetics of glucose metabolism were evaluated in rats deprived of food 15-21 h after the administration of hypoglycaemic doses of hypoglycin (100 mg/kg body wt.) by following changes in the specific radioactivities of 14C and 3H in blood glucose after an intravenous dose of [U-14C,2-3H]glucose [Katz, Rostami & Dunn (1974) Biochem. J. 142, 161-170]. 2. During this time, recycling of glucose through the Cori cycle was virtually abolished, the rate of irreversible disposal of glucose and its total body mass were both decreased by about 70%, whereas there was little effect on the mean transit time for glucose. 3. It was concluded that hypoglycaemia is due to inhibition of gluconeogenesis.

ABSTRACT Atlantirivulus riograndensis (Costa & Lanés, 2009) is a fish registered to the basin of Patos lagoon and the adjacent coastal plains in southern states of Rio Grande do Sul and Santa Catarina, Brazil, found in shallow water courses with that have large quantities of aquatic vegetation and forest edges. The objective of this study was to investigate the reproductive strategy and tactics of this species including the sex ratio, the length at first maturity, spawning type, fecundity and the possible associations among reproduction and abiotic factors. Sampling of specimens occurred in perennial wetlands within the Banhado dos Pachecos wildlife refuge, in the city of Viamão, state of Rio Grande do Sul, Brazil, which is a conservation unit that belongs to an area of environmental protection in the Pampa Biome. The capture of 30 A. riograndensis specimens per month occurred from January to December of 2012. A total of 188 females and 172 males were captured and the total sex ratio was 1:1 in the sampled population. Sexual maturity of the species occurs after 13.59 and 11.92 mm (SL) for females and males, respectively. Both a multiple spawning and a long reproductive period (since August to March) were confirmed by the presence of post-ovulatory follicles that were observed through histological analysis and the values of the gonadosomatic index in females considered spawning capable. The average absolute fecundity of the species is of 19.33 (± 6.18) vitellogenic oocytes in mature ovaries. No significant relationship was found between mean GSI and the abiotic data. Reproductive tactics presented by A. riograndensis indicate a species with an opportunistic reproductive strategy, following the pattern of other species of the Rivulidae family.

ABSTRACT Objective: The study aimed to determine the association between postural changes and practice of classical ballet among ballerinas from Integrated Administrative Region of Development (RIDE) in Polo Petrolina/PE and Juazeiro/BA. Methods: Cross-sectional observational study with 19 classical ballerinas aged over 15 years and at least 5 years of uninterrupted classical ballet practice. The anthropometric assessment included measurements of total body mass, height and body mass index (BMI). Postural evaluation was performed using the photogrammetric method with help of Posturograma(r) and SAPO(c) software. Results: The mean age was 25.3±11.7 years and the mean BMI was 21.4±2.9 kg/m². Approximately 74% of classical ballerinas had normal anthropometric profile. The postural profile of the classical ballerinas showed inclination and protrusion of the head, trunk rotation, rectification of cervical lordosis, increased thoracic kyphosis, increased lumbar lordosis, pelvic inclination and anteversion. Conclusion: The practice of ballet led to changes in body alignment of the classical ballerinas evaluated. The results points out to the need of postural re-education in order to contribute for the kinetic-functional balance of classical ballet practitioners.

A study on the reproductive strategy of Chrysichthys nigrodigitatus was conducted from October 2015 to August 2016, in the Nkam River in Yabassi, Littoral Region of Cameroon. For this purpose, 154 specimens of C. nigrodigitatus with total mean weight of 829.96 ± 829.58 g and total mean length of 367 ± 156 mm collected from artisanal fishermen were used. Twenty-nine (29) females at stage V of sexual maturity were selected for the evaluation of the fecundity. It appears that the oogenesis in C. nigrodigitatus is of an asynchronous type with multiple laying spread over a long period. The gonadosomatic index (GSI) peaks in June (17.9 ± 7.1 for females and 1.06 ± 0.27 for males). Hepatosomatic index (HSI) was higher in females than in males throughout the year. The mean condition factor K was 1.07 ± 0.09%. The breeding season occurred from April to October during the rainy season. Gonadosomatic and hepatosomatic indices were positively correlated with rainfall, contrary to the K factor, which has been strongly and negatively correlated with this physical parameter. The sex ratio of 1M: 1.5F was in favour of females, thus reflecting an “r” type reproductive strategy. Absolute fecundity was estimated at 1374 ± 1022 oocytes for individuals of 107.3 ± 111.9 g mean weight. Mean relative fecundity was 14 ± 3 oocytes/g of body weight. It was recommended that future work focuses on the captivity of this species.

Parrot Population

Parrots are ornamental birds that are found in the wild and those in domestication end up in animal units of schools and houses of the wealthy individuals. The wild African Senegal parrot population is at risk of extinction due to its high popularity with urban dweller. Despite their high popularity, there is scanty documentation of the anatomical features of its gastrointestinal tract (GIT). The Wild West African Senegal Parrots were caught around forested area of a farm settlement in Shika, Zaria, Kaduna state, in the Northern part of Nigeria. The mean body weight of the wild Senegal parrot was observed to be 120.50 ± 5.42 g. The mean weights of the GIT with content and without content were 18.01 ±4.80 g and 13.54 ± 5.51 g respectively which accounted for 12.95 % and 10.24 % of the total body mass. The mean weights (small and large intestines) were 2.10 ± 1.09 g and 0.70 ± 0.27 g. The caecum was not noticed and gall bladder had the least mean weight 0.17 ± 0.007 g. while the gizzard the highest of all mean weight 4.28 ± 2.25 g. The mean lengths (GIT, small and large intestines) were; 82. 61 ± 2.36 cm, 41.75 ± 2.97 cm and 18.06 ± 2.01 cm. The glandular area of the proventriculus was longer than the non glandular portion and the left liver was longer compared to the right 3.03 ± 1.53 cm. The ileum is the longest segment of the small intestine which constituted 22.90 ± 2.92 cm.Keywords: Macrometry, Gastrointestinal Tract, Senegal Parrots

This study was undertaken to investigate the total body and segmental centers of mass of individuals with Down’s syndrome. The 40 subjects were divided equally by gender into the following age groups: (a) ages 6 to 10, (b) ages 11 to 18, (c) adult females, and (d) adult males. Data on mass centroid locations were collected through a photogrammetric technique. Frontal and right sagittal-view slide photographs on each subject were digitized and the data logged into a computer program. The program calculated the segmental mass centroid locations and total body center of mass. Differences in total body and segmental center of mass locations were found between individuals with Down’s syndrome (DS) and nonhandicapped individuals. Analysis of the data on the DS children indicated that the mean center of mass location for the total body was within the range reported for nonhandicapped children. The adult DS male and female subjects were found to have a lower total body center of mass when compared to existing data on nonhandicapped adults. It was also found that the segmental mass centroid locations for the head and trunk segment of DS subjects were consistently lower than those found in nonhandicapped individuals. This finding points to an overall lowering of the center of mass found with DS subjects.
