This study was conducted in the Korhogo region in an age gradient of mango orchards. The goal was to assess diversity and determine the influence of the environment on the composition of these organisms. Sampling was done using pitfall traps, threshing and manual collection. A total of 82 ant species were sampled on all plots. The cultivated plots are richer in ant species than the natural environment. Of the three (3) sampling methods, the Manual Collection proved to be more efficient (eff = 79.52%), followed by threshing (eff = 75.15%) and finally the least effective trap pit (eff = 73.39%). The number of individuals of the species varies according to the environment. The highest value was obtained in the young plot (485 individuals), followed by the intermediate plot (478 individuals), then the older plot (426 individuals) and finally the control plot (320 individuals). The species Camponotus acvapimensis was harvested mainly with 159 individuals. On the other hand, the species Lepisiota sp.1;Camponotus rufigenis, Camponotus sericeus and Oecophylla longinoda were specifically harvested in the control, young, intermediate and aged plots, respectively. 展开更多

In this paper, the relationship between the geodynamics and cosmic expansion is analyzed and demonstrated from the basic physical principles and various natural phenomena, and the conclusion is drawn that cosmic expansion is the dynamic force source of all planetary tectonic movements in the universe. The energy for the formation and change of landscape and the energy of earthquakes and volcanic eruptions all come from the cosmic expansion. With the cosmic expansion, the energy density of space is decreasing, the atoms and molecules of all matter in the universe are growing, and the magma is expanding and producing gases. As the earth’s internal pressure rises, the mechanical energy that accumulates within the magma forms the driving force of the earth’s various tectonic movements, and the release of these energy and matter (expansive magma and high-pressure gases) leads to the formation and the changes of the landform (such as orogenesis, epeirogenesis, the formation of the earth’s plates, the Earth expansion, the seafloor spreading, and the continental drift), as well as to earthquakes and volcanic eruptions. In this paper, the causes of all kinds of earthquakes, especially deep focus earthquakes, are given and almost all known seismic phenomena are explained, the basic principle and method of earthquake prediction are given, and the direction is pointed out for the elimination of earthquakes and the utilization of earthquake energy. Based on the same principle of physics, this paper also shows that the Ice-Age is caused by the acceleration of the speed of the motion of the solar system relative to the Milky Way in certain regions of the Milky Way. The greater the speed of the solar system relative to the Milky Way, the greater the drop in Earth surface temperature. 展开更多

Background: The relationship between splenic size and age has been well studied in children but reports on adults have been inconsistent. In Nigeria, the relationship between splenic size and age as well as the inter-decade changes in splenic length in adults has not been adequately studied. Objectives: This study aimed at determining the relationship between splenic length and age in adult Nigerians. Methods: This is a retrospective study in which sonographic splenic lengths of adult Nigerians aged 30 years and above were correlated with age. The relevant data were obtained from the medical records of those who had ultrasound splenic examination for the purposes of medical check-up between December 2016 and December 2017. Results: There were 50 cases aged between 34 and 57 years, with a mean age of 42.76 ± 7.73 years. Their spleens had normal shape and echotexture. The mean splenic length was 9.56 ± 1.37 cm. Splenic length correlated negatively with age and decreased from 9.79 ± 1.00 cm in the fourth decade to 9.49 ± 1.67 cm in the fifth decade and to 9.24 ± 1.63 cm in the sixth decade. The mean splenic length of 9.56 recorded in these cases was relatively small when compared to the results by other workers who studied subjects of much younger age groups. Conclusion: The studied cases which were in the fourth, fifth and sixth decades of life had a relatively small mean splenic length. There was no significant change in splenic length with increasing age. 展开更多

Thyroid hormones have various effects on the reproductive system of female. PCOS and thyroid dysfunction are linked to each other since several years. Objective: To evaluate and detect the thyroid dysfunction in patients with PCOS attending in a tertiary care hospital in Bangladesh. Methodology: This was a prospective cross sectional study conducted from November 2018 to October 2019 at Department of Obstetrics and Gynecology in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on one hundred and fifty (150) PCOS women of reproductive age (15 - 45 years). All data of the study subjects regarding socio-demographic, anthropometric and clinical manifestations were recorded accordingly. Their thyroid function tests (serum level of FT3, FT4, TSH) were done at the hospital laboratory and results were recorded. Result: Mean (±SD) age of the study subjects was 24.57 ± 4.27 years. The maximum numbers [108 (72.0%)] of PCOS women were between 18 - 25 years age group. Among total (150) study population, 51 (34.0%) were overweight, 36 (24.0%) were obese and 63 (42.0%) were within normal weight level. Hirsutism was found in 87 (58%) study subjects while 24 (16%) subjects had acne in their face, 54 (36%) subjects had oligomenorrhea and 45 (30%) subjects had irregular periods. Among 150 PCOS women, 120 (80%) were married and 30 (20%) were single;of them primary infertility was detected in 58 (48.33%) women followed by the normal fertility status [51 (42.5%)] and 11 (9.17%) had secondary infertility. Among total (150) study subjects, 105 (70%) were in euthyroid state, hypothyroidism was found in 33 (22.0%) subjects and hyperthyroidism was detected in 12 (8%) subjects. Conclusions: Present study demonstrated that, thyroid disorders are prevalent in 30.0% of PCOS patients. Hypothyroidism is almost three-fold more prevalent than hyperthyroidism. 展开更多

Although some porphyry-skarn deposits occur in post-collisional extensional settings,the post-collisional deposits remain poorly understood.Here the authors describe the igneous geology,and mineralization history of Tuolangla,a newly-discovered porphyry-skarn Cu-W-Mo deposit in southern Tibet that belongs to the post-collisional class.The deposit is associated with Lower Cretaceous Bima Formation.It was intruded by granodiorite porphyry intrusions at about 23.1 Ma.Field investigation indicated that mineralization is spatially and temporally associated with granodiorite porphyry.Molybdenite yielded a Re-Os weighted mean age of 23.5±0.3 Ma and is considered to represent the age of skarn mineralization at the deposit.Theδ^34S values of sulfides,concentrated in a range between 0.6‰to 3.4‰,show that the sulfur has a homogeneous source with characteristics of magmatic sulfur.The Pb isotopic compositions of sulfides indicate that ore-forming metal materials were derived from the mantle and ancient crust.The granodiorite porphyry displays high SiO2(68.78%–69.75%)and K2O(3.40%–3.56%)contents,and relatively lower Cr(2.4×10^-6–4.09×10^-6),Ni(2.79×10^-6–3.58×10^-6)contents,and positiveεHf(t)values(7.7–12.9)indicating that the mineralization porphyry was derived from the partial melting of juvenile lower crust.The Tuolangla deposit is located in the central part of Zedang terrane.This terrane was once considered an ancient terrane.This terrane is in tectonic contact with Cretaceous ophiolitic rocks to its south and Mesozoic continental margin arc volcanics and intrusions of the Gangdese batholith of the Lhasa terrane to its north.Thus,the authors proposed that the Oligocene porphyry skarn Cu-W-Mo mineralization is probably associated with the Zedang terrane.This finding may clarify why the Oligocene(about 23 Ma)deposits are found only in the Zedang area and why mineralization types of the Oligocene mineralization are considerably different from those of the Miocene(17–14 Ma)mineralization. 展开更多

Each molecular subtype defines different disease behavior and requires different treatment. The different molecular subtypes have different risk factors and different distribution across age classes. Aim of the study: To detect the incidence of cancer breast subtypes by age among Egyptian patients treated at the Clinical Oncology Department, Faculty of Medicine, Ain Shams University, in the period between April 2016 and December 2018. Patients and Methods: Inclusion criteria: Cases with proven pathological diagnosis and underwent IHC studies for the molecular subtype while exclusion criteria were: Bilateral cases, cases with unknown molecular subtype or age at presentation, cases with multiple primaries, cases with in situ cancer, male breast cancer cases, and cases diagnosed during pregnancy. Age classes were computed in four groups: from 20 - 35, >35 - 50, >50 - 65 and those older than 65 years of age. Immunohistochemical studies were done;ER, PR and HER2 were recorded for each case, Molecular subtypes were defined as follows: HR+/HER2-, HR+/HER2+, HER2 overexpressed (HER2 positive, HR-) and Triple Negative Breast Cancer;TNBC (HER2 negative, ER negative and PR negative). Results: one thousand and two cases were included in the study. The median age was 51 years and the mean age was 51.64 ± 11.74, with range from 24 to 85 years. The total number of ER positive patients was 706 patients (70.5%), the total number of PR positive patients was 667 (66.6%), and the total number of Her2 positive patients was 286 patients (28.5%). While there were no statistically significant differences in the incidence of ER and PR positivity among all age classes, Her2 over expression decreased with age and the difference was statistically significant (P-value: 0.012). Her2 overexpression subtype incidence decreased by age and it was highest in the younger age group 17.6% compared to 8.2% in the older age group and the difference was statistically significant.

About a third of women affected are aged less than 40 years. Chemotherapy (CT) could alter ovarian function and thereby compromise future fertility in these women. We therefore described the fertility of women following CT for BC in women treated at the Yaounde General Hospital (YGH). Methods: It was a retrospective, descriptive, cross-sectional study conducted over 8 months, from January to August 2017. We used the files of patients managed for BC from January 2011 to December 2015 in the medical oncology unit of the YGH. Results: We included 265 patients for the study following at least one year of CT. The mean age at the onset of CT was 35.9 ± 6.9 years. Most of the patients had fewer than 2 deliveries (68.3%). Intraductal carcinoma was the most frequent histological lesion (90.6%) and most often diagnosed in advanced stages (73.5%). As per CT, the FAC protocol was the most used (44.5%). The menstrual cycles of the patients were more regular prior to the onset of chemotherapy (89.4% vs. 58.9%), while the mean period of resumption of menstrual activity following cessation of chemotherapy was 6.3 ± 2.0 months. Chemotherapy-related amenorrhoea was observed in 29.1% of patients after 12 months of treatment. More than half of these women (51.3%) complained of a drop in libido and 6.4% achieved pregnancy within 13 months following cessation of chemotherapy. Conclusion: Following chemotherapy for BC, menstrual cycle disorders are more frequent and this can affect the patients’ reproductive potential. Fertility consultations should be integrated into the management plan of such patients. 展开更多

Previous studies have focused on the damaging effects of smoking and alcohol on sperm parameters;however, some of these studies have failed to find a significant correlation between these variables. Herein we have investigated the relationship of infertility with smoking and/or alcohol consumption in one hundred and thirty-six men with varicocele, admitted consecutively to the Outpatients Department of Infertility at the University of Rome La Sapienza (Italy) between 2005-2007. The sample size was small because we have selected couples with both marital infertility lasting for more than two years and the male partner with varicocele. Statistical analyses were carried out using the software of Statistical Package for the Social Sciences (SPSS). We showed a highly significant association of infertility with alcohol consumption. As the mean value was 32 years, comparing men of age less than or equal to 32 years and men of age over 32 years, this association is present only in men of age less than or equal to 32 years. A discriminant analysis with infertility as dependent variable and age, alcohol consumption and smoking habit as independent variables has shown a significant discrimination only in men of age less than or equal to 32 years. The most important contribution to this discrimination was given by alcohol followed by age while contribution from smoking was small. Our analyses suggest that alcohol consumption contributes to infertility in men of age less than or equal to 32 years whereas smoking does not. 展开更多

In 2013, World-Universe Model (WUM) proposed a principally different way to solve the problem of Newtonian Constant of Gravitation measurement precision. WUM revealed a self-consistent set of time-varying values of Primary Cosmological parameters of the World: Gravitation parameter, Hubble’s parameter, Age of the World, Temperature of the Microwave Background Radiation, and the concentration of Intergalactic plasma. Based on the inter-connectivity of these parameters, WUM solved the Missing Baryon problem and predicted the values of the following Cosmological parameters: gravitation G, concentration of Intergalactic plasma, relative energy density of protons in the Medium, and the minimum energy of photons, which were experimentally confirmed in 2015-2018. Between 2013 and 2018, the relative standard uncertainty of G measurements decreased x6. The set of values obtained by WUM was recommended for consideration in CODATA Recommended Values of the Fundamental Physical Constants 2014. 展开更多

Introduction: The impact of growth hormone therapy in children with short stature on cardiovascular prognosis seems to be unpredictable from big databases. The enhanced cardiovascular risk in this group of patients may be related to adverse autonomic imprinting by early life stress. Autonomic dysfunction and possible effects of growth hormone therapy on the autonomic nervous system can be measured easily by calculating heart rate variability (HRV) from Holter electrocardiogram monitoring. Methods: We performed HRV analysis prior to growth hormone therapy (N = 33), within the first year of growth hormone therapy between 4 and 10 years of age (N = 19), at least a further HRV measurement between 10 and 15 years (N = 30). Additional measurements were performed before and after cessation of growth hormone therapy (N = 14). Data were compared to untreated pediatric patients with short stature and to age matched healthy controls. Results: Untreated patients with short stature due to growth hormone deficiency or intrauterine growth restriction in early childhood have significantly increased heart rates most of all at night and concomitantly reduced global HRV indicated as Standard Deviation of Normal to Normal Intervals (SDNN). Growth hormone treated adolescents and the untreated patients with short stature show significantly elevated mean heart rates and concomitantly reduced vagus activities measured as reduced Route Mean Square Standard Deviation (RMSSD). After cessation of growth hormone treatment SDNN significantly increases and heart rate decreases to normal values in formerly treated patients with catch-up growth. Conclusion: There is a comparable autonomic dysfunction in treated and untreated children with short stature as an indicator for enhanced cardiovascular risk. After cessation of growth hormone therapy, we found a significant improvement of reduced HRV to normal values. 展开更多

The prostate examination included digital rectal examination and measurement of serum prostate-specific antigen levels. Demographic and clinical characteristics of subjects were obtained using a structured questionnaire. The serum levels of Testosterone (Te), Luteinizing hormone (LH), Follicle stimulating hormone (FSH) and Prolactin (PRL) were measured using ELISA method. <strong>Results:</strong> Our study indicated that age and levels of prostate specific antigen (PSA), LH and FSH were significantly (p < 0.05) higher in men with BPH compared with healthy controls. In contrast, the control group indicated significantly (p < 0.05) higher Te level compared with the BPH group. In patients with BPH, age was significantly (p < 0.05) correlated with the hypothalamic-pituitary-testicular axis hormones (LH, FSH and PRL), but not with the sex hormone, and testosterone. Majority (62.1%) of the patients with BPH indicated they had poor libido, while none of them indicated regular sexual activity with their spouses. <strong>Conclusion:</strong> This study suggests that the rise in serum levels of the hypothalamic-pituitary-testicular axis hormones in BPH patients as demonstrated by the present findings may be age-related since testicular dysfunction in aging men is associated with the decrease in androgen production which may stimulate an increased production of gonadotropins by negative feedback. 展开更多

The analysis results showed that the positions entered into the regression model (OR = 2.339);the expected retirement age (OR = 3.280);and delayed retirement can better solve the pension problem (OR = 0.553). Retirement can relieve child financial pressure (OR = 0.217), emotional exhaustion (OR = 0.913) and social opportunities (OR = 1.132). The OR of job title, expected retirement age, and social opportunities is greater than 1, and the others are less than 1. <strong>Conclusion:</strong> The most expected retirement age for nurses is 50 to 55 years old, and they are more inclined to retire early. Factors affecting the willingness to postpone retirement include position and expected retirement age. Postponement of retirement can better solve pension problems. Postponement of retirement can alleviate child financial pressure, social opportunities and emotional exhaustion. </p> 展开更多

The objective was to evaluate the impact of gender and age on the profile of Graves’ disease in Senegalese subject in order to understand the evolution and improve the therapeutic choices. <strong>Methods:</strong> This is a retrospective study conducted from January 1, 2010 to December 31, 2017 (07 years) at Abass Ndao University Hospital (Senegal), focused on patients with Graves’ disease followed up under antithyroid drugs treatment for at least 18 months. <strong>Results:</strong> There were 244 men, 404 subjects between [0 - 25 years], and 101 subjects more than 50 years old. Factors associated with goitre size were male gender (p < 0.001), young age (p < 0.001). Graves orbitopathy was correlated with male gender (p = 0.015), and young age (p < 0.001). Among 580 patients who had stopped medical treatment after more than 18 months of follow-up, relapse involved in 30.3%. Durable remission was achieved in 38.8% of all included patients and 69.7% of subjects who had a cessation of medical treatment. The factors associated with sustained remission were female gender (p = 0.049), absence of orbitopathy (p = 0.011), small goiter (p < 0.001), advanced age (p = 0.006) and early start of the maintenance treatment (p = 0.006). <strong>Conclusion:</strong> In our Senegalese study, men and young patients are particularized by a trend of voluminous goitre and low rate of remission. These data remain a basis for predicting the outcome of medical treatment and make timely use of radical treatments such as surgery or irratherapy in the presence of risk factors for recurrence. 展开更多

Technological advances, a deeper understanding of disease processes and increased sophistication of therapeutic methods have all led to better outcomes in rare diseases which previously had devastating effects on many women’s lives. The inevitable result of this progress is that women, who in the past did not contemplate pregnancy because of significant morbidity, now get to adulthood and are reasonably “disease free” enough to have their own families. The ever expanding, but relatively new specialty of Obstetric medicine seeks to further improve the outcome in pregnant women with intercur</span><span style="font-family:"">r</span><span style="font-family:"">ent disease by enhancing the literature base, thereby contributing to the creation of appropriate guidance in the management of these patients. This article is a brief but useful guide for the busy obstetrician who may have limited experience in dealing with multiple sclerosis in pregnant women. 展开更多

Median age at presentation was 4 years, range 1 day - 16 years. Males 73 (100%), only 17 (23.3%) were referred by health personnel, while 56 (76.7%) self-referred. Commonest site involved was the left 33 (45.2%), 29 (39.7%) right and 11 (15.1%) bilateral.

Hypospadias 7</span><span style="font-family:Verdana;"> (53.8%), isolated micropenis 4 (30.8%) and 1 each (7.7%) had myelomeningocele and hernia. Median age at presentation for bilateral involvement was 30 days, with associated hypospadias was 12 days, while those with isolated micropenis was 7.5 years. Median age at surgery for bilateral involvement was 2 years, overall median age at surgery was 4 years. </span><b><span style="font-family:Verdana;">Surgery Findings:</span></b><span style="font-family:Verdana;"> Supra-scrotal testis 47, canalicular 25 (34.2%), and bilateral abdominal 1 (1.4%). </span><b><span style="font-family:Verdana;">Outcome:</span></b><span style="font-family:Verdana;"> Wound infections 4 (5.5%), scrotal wound breakdown 1, Recurrence 3 and testicular atrophy 1. </span><b><span style="font-family:Verdana;">Conclusion:</span></b><span style="font-family:Verdana;"> Our patients presented very late beyond the recommended age for surgery, evaluating for DSD also contributed to delay in intervention even when these patients presented early.
