Abstract:

Abstract. A novel and non-invasive technique of growth measurement is introduced. By this method the length of the human lower leg is measured with an accuracy of 0.1 mm. Thus, growth velocities can be estimated within a few weeks. In the present study the immediate changes of growth velocity are demonstrated, following the transfer of growth hormone administration from three times weekly im to daily sc in 9 growth hormone deficient children, age 7.4 to 20.5 years. The first observation period (3 times weekly im administration) ranged from 32 to 72 days, the second observation period (daily sc

Abstract. Two patients, aged 5 and 12 years, with Silver-Russell type dwarfism are presented. As shown by standard tests and examination of the spontaneous nocturnal hGH secretion, there was only mild regulative hGH deficiency. HGH treatment was started with daily subcutaneous injections at age 5.5 years (height 90.3 cm, −6.1 SDS, bone age 2.75 years) and 12.6 years (height 125.7 cm, −3.7 SDS, bone age 8.75 years), respectively. Treatment was monitored by serial somatomedin-C (SM-C) determinations and by knemometry (lower leg measurement). SM-C values increased in both patients by 10.5 and 4.8

Abstract:

✓ The growth and metastatic behavior of five human glioblastoma multiforme xenografts and nine human xenografts of various histological types were compared in severe combined immunodeficient (SCID) mice. The results demonstrate that the metastatic behavior of the human glioblastoma multiforme xenografts did not differ significantly from a variety of other histological xenografts when evaluated at the same transplantation site in the SCID model. These results are consistent with the hypothesis that the site of glioblastoma multiforme growth influences the extraneural metastatic spread of this d

Heat therapy has been shown to promote capillary growth in skeletal muscle and in the heart in several animal models, but the effects of this therapy on angiogenic signaling in humans are unknown. We evaluated the acute effect of lower body heating (LBH) and unilateral thigh heating (TH) on the expression of angiogenic regulators and heat shock proteins (HSPs) in healthy young individuals.

Abstract:

Background Humans life histories have been described as “slow”, patterned by slow growth, delayed maturity, and long life span. While it is known that human life history diverged from that of a recent common chimpanzee-human ancestor some ~4–8 mya, it is unclear how selection pressures led to these distinct traits. To provide insight, we compare wild chimpanzees and human subsistence societies in order to identify the age-specific vital rates that best explain fitness variation, selection pressures and species divergence. Methods We employ Life Table Response Experiments to quantify vital rate

The results revealed that compared with normal walking, Tai Chi movement had more double support and less single support total duration. The duration of each support pattern was longer and movement from

Abstract:

This chapter focuses upon one particular geographic region in suburban Washington, DC, which serves as a microcosm for the challenges and opportunities of the larger drug development enterprise. Our story begins with the efforts to sequence the human genome, an ambitious project that led to an increasingly bitter and highly publicized rivalry between the personalities of Craig Venter and Francis Collins from the private and public sectors, respectively. This same initiative gave rise to the dramatic growth in a cadre of biotechnology companies in suburban Maryland dedicated to exploiting the commercial opportunities associated with the human genome. The bubble would ultimately be burst as a result of various legal and executive decisions and in doing so, obliterated billions of dollars in wealth and effectively shudder an entire sector. All the while, another upstart biotechnology company, MedImmune, continued on a lower profile but ultimately more successful path to introduce innovative new medicines. However, this company would itself suffer a series of setbacks of its own making that resulted from the failed commercial launch of an improved influenza vaccine.

Abstract:

Comparative endocrinology is the study of the endocrine glands and their hormones in different species of animals. It is undergoing a renaissance because of the new tools and techniques provided by genome sequencing and molecular biology. Until relatively recently, characterization and detection of hormones in lower vertebrates relied on biological assays and protein chemistry approaches, whereas now gene sequences can be readily revealed from whole genome sequencing. Gene expression and synthesis can be used to develop antibodies and other reagents for sensitive assays and revealing physiological experiments can be carried out. Endocrinology traditionally used a range of animal species, including many lower vertebrates. Comparative endocrinology became a separate specialty only in the last 50 years when endocrinologists concentrated on rodents as their model animals. In 1933, Riddle demonstrated that an avian pituitary factor that promoted growth of the pigeon crop-sac was identical to a mammalian pituitary factor that earlier had been found to initiate and maintain milk secretion in mammals. Riddle called this avian factor prolactin and the response of the crop-sac provided a sensitive assay for the detection of human prolactin in pituitary extracts. Pigeon prolactin was the first pituitary hormone to be crystallized and purified in 1937 and led to the purification of mammalian prolactin. Prolactin has a number of roles in lower vertebrates, including a vital role as a hypercalcaemic factor in fish. The first part of this chapter focuses on the calcium-regulating factors including parathyroid hormone (PTH), parathyroid hormone-related protein (PTHrP), and stanniocalcin (STC), and the second part will discuss comparative endocrinology of thyroid hormones and transthyretin (a thyroid hormone distributor in blood the cerebrospinal fluid).

A lightweight adjustable exoskeleton is designed to exercise human legs of varying size and weights. The exoskeleton is actuated by three DC motors at the hip, knee, and ankle. An experimental setup with motor controllers, power supplies, a controlled board, and a computer is developed for closed loop control. A sliding mode control law is designed and implemented to exercise an articulated mannequin leg. It is shown that the exoskeleton is able to adapt to external forces making it suitable to aid in the human leg rehabilitation process.

Abstract:

The field of control of powered lower-leg prostheses has advanced due to the improvements in sensors and computational power. Much effort has been done to improve the capabilities of prostheses, such as mimicking the stiffness, weight, and mobility of a human ankle-foot [1] and autonomously commanding the robotic prosthesis for gait [2].

Abstract:

The first functional load-carrying and energetically autonomous exoskeleton was demonstrated at U.C. Berkeley, walking at the average speed of 0.9 m/s (2 mph) while carrying a 34 kg (75 lb) payload. The original BLEEX sensitivity amplification controller, based on positive feedback, was designed to increase the closed loop system sensitivity to its wearer’s forces and torques without any direct measurement from the wearer. The controller was successful at allowing natural and unobstructed load support for the pilot. This article presents an improved control scheme we call “mixed” control that

Abstract:

This rapid review synthesises the literature from academic, policy, and knowledge institution sources on how demography affects labour markets (e.g. entrants, including youth and women) and labour market outcomes (e.g. capital-per-worker, life-cycle labour supply, human capital investments) in the context of sub-Saharan Africa. One of the key findings is that the fast-growing population in sub-Saharan Africa is likely to affect the ability to get productive jobs and in turn economic growth. This normally happens when workers move from traditional (low productivity agriculture and household bus

Abstract:

The Kyrgyz Republic has overcome some complex challenges to now have one of the most open economies in Central Asia. The country has improved its per capita income and living standards and is on the threshold of becoming a lower-middle-income economy. Looking ahead, the main challenge for the Kyrgyz Republic is to build on these successes to stimulate stronger, more broad-based economic growth. This book identifies the economic and governance reforms needed within key sectors to drive this growth. It provides policy suggestions to enhance the country’s trade, agriculture, tourism, finance, inf
