No full textEstrogen depletion leads to bone loss in almost all mammals with frequent regular ovarian cycles. However, subordinate adult female common marmosets (Callithrix jacchus) undergo socially induced anovulation and hypoestrogenism without clinically apparent adverse skeletal consequences. Thus, we speculated that this non human primate might have evolved a mechanism to avoid estrogen-depletion bone loss. To test this possibility, we performed three experiments in which lumbar-spine (L5-L6) bone mineral content (BMC) and density (BMD) were assessed using dual-energy X-ray absorptiometry: (i) cross-sectionally in 13 long-term ovariectomized animals and 12 age- and weight-matched controls undergoing ovulatory cycles; (ii) longitudinally in 12 animals prior to, 3-4 and 6-7 months following ovariectomy (ovx), and six controls; and (iii) cross-sectionally in nine anovulatory subordinate and nine dominant females. In Experiments 1 and 3, plasma estradiol and estrone concentrations were measured and uterine dimensions were obtained by ultrasound in a subset of animals as a marker of functional estrogen depletion. Estrogen levels, uterine trans-fundus width, and uterine dorso-ventral diameter were lower in ovariectomized and subordinate females than in those undergoing ovulatory cycles. However, no differences were found in L5-L6 BMC or BMD. These results indicate that estrogen depletion, whether surgically or socially induced, is not associated with lower bone mass in female common marmosets. Thus, this species may possess unique adaptations to avoid bone loss associated with estrogen depletion.R03 MH60728/MH/NIMH NIH HHS/United StatesP01 AG11915/AG/NIA NIH HHS/United StatesP01 AG011915/AG/NIA NIH HHS/United StatesR03 AG15621/AG/NIA NIH HHS/United StatesP51 OD011106/OD/NIH HHS/United StatesIBN-9604321/National Science Foundation/InternationalP51 OD011106/CD/ODCDC CDC HHS/United StatesR01 MH060728/MH/NIMH NIH HHS/United State
Simplified Attachable EEG Revealed Child Development Dependent Neurofeedback Brain Acute Activities in Comparison with Visual Numerical Discrimination Task and Resting
No full textThe development of an easy-to-attach electroencephalograph (EEG) would enable its frequent use for the assessment of neurodevelopment and clinical monitoring. In this study, we designed a two-channel EEG headband measurement device that could be used safely and was easily attachable and removable without the need for restraint or electrode paste or gel. Next, we explored the use of this device for neurofeedback applications relevant to education or neurocognitive development. We developed a prototype visual neurofeedback game in which the size of a familiar local mascot changes in the PC display depending on the user’s brain wave activity. We tested this application at a local children’s play event. Children at the event were invited to experience the game and, upon agreement, were provided with an explanation of the game and support in attaching the EEG device. The game began with a consecutive number visual discrimination task which was followed by an open-eye resting condition and then a neurofeedback task. Preliminary linear regression analyses by the least-squares method of the acquired EEG and age data in 30 participants from 5 to 20 years old suggested an age-dependent left brain lateralization of beta waves at the neurofeedback stage (p = 0.052) and of alpha waves at the open-eye resting stage (p = 0.044) with potential involvement of other wave bands. These results require further validation

No full textThe The rapid development of science and technology has encouraged people to seek and implement new ways and methods in the process of work in order to run more easily and smoothly. By looking at the current technological sophistication, especially information and communication technology that can help facilitate the work of an organization or company that can be used as consideration in making a decision and provide timely and accurate information. So the author tries to take advantage of this to design an application Management Applications Communications And Information At Anisa Apotek as a tool to improve the effectiveness and accuracy of work, which during this process of data processing on Apotek anisa still done manually. With this application, it is expected Anisa Pharmacy can be more developed, so many customers who use it.</p
Fathering style influences health outcome in common marmoset (Callithrix jacchus) offspring.
No full textIn the cooperative breeding common marmoset monkey, Callithrix jacchus, fathers share the care responsibility and energetic load with their mate from the time their infants are born. However, not all fathers show the same level of participation in direct infant care. Here we present the first results demonstrating that fathering style can improve both survival and growth trajectory of a male's offspring during the first 30 weeks of life and that these infant outcomes are consistent within a father throughout successive births. Twenty-four marmoset fathers were tested for their responsiveness to an infant distress call when their infants were approximately two weeks old. These fathers were categorized as either responsive (RS) or nonresponsive (NRS) based on their response to the calls. Survival past 1 month was then determined and bi-monthly weights of current infants through 30 weeks of age were taken. Infant survival to the first month was significantly higher with RS fathers than with NRS fathers during this critical time period. Infants from RS fathers also had a higher growth trajectory with significant differences in body weight in the 28th and 30th week after birth. Only the RS fathers showed a significant increase in serum testosterone in response to infant cries suggesting a physiological role of testosterone in the motivation to search for the infant. Furthermore, all offspring born to RS fathers from subsequent births also showed a significantly higher survival rate and higher growth trajectory than for offspring of NRS fathers. These results suggest that fathering style is a consistent trait and responsive fathers improve infant survival rate and growth during the first 30 weeks. Such fathering style traits may be passed on to the male offspring due to environmental or genetic factors

No full textThe article discusses the carnivorous plant the Purple Pitcher Plant, or Sarracenia purpurea L., on Prince Edward Island. It focuses on research at the University of Prince Edward Island (UPEI) on the Purple Pitcher Plant, noting its presence in bogs such as the Glenfinnan Bog. The author comments on research conducted by UPEI undergraduate students Ricki Sulis and Vaneeta Verma from the laboratory of biologist Christian Lacroix on pitcher plant developmental morphology and anatomy and on research conducted by undergraduate students Loretta Hardwick, Dylan Blacquiere, and Jackie Wood from the laboratory of entomologist D.J. Giberson on aquatic insects that live inside pitcher plants.Source type: Print(0
