Caloric restriction (CR) protects against aging and disease, but the mechanisms by which this affects mammalian life span are unclear. We show in mice that deletion of ribosomal S6 protein kinase 1 (S6K1), a component of the nutrient-responsive mTOR (mammalian target of rapamycin) signaling pathway, led to increased life span and resistance to age-related pathologies, such as bone, immune, and motor dysfunction and loss of insulin sensitivity.

Age-related bone loss is well established in humans and is known to occur in nonhuman primates. There is little information, however, on the effect of dietary interventions, such as caloric restriction (CR), on age-related bone loss. This study examined the effects of long-term, moderate CR on skeletal parameters in rhesus monkeys. Thirty adult male rhesus monkeys were subjected to either a restricted (R, n = 15) or control (C, n = 15) diet for 20 years and examined throughout for body composition and biochemical markers of bone turnover.

OBJECTIVES: To determine if long-term weight loss with associated improvement in physical and metabolic health can be maintained after lifestyle intervention in frail, obese older adults. DESIGN: Thirty-month follow-up pilot study of a 1-year lifestyle intervention trial. SETTING: Community. PARTICIPANTS: Sixteen frail, obese (body mass index=36±2 kg/m2) older (71±1 yr.) adults.

BACKGROUND: Current medical applications for diagnostic ultrasound are numerous. The technology is attractive because of its ease of use, noninvasive nature and low cost. Recent technological advances have improved ultrasound images of spine-related soft tissues. OBJECTIVE: To examine and summarize the spine-related diagnostic ultrasound literature to help aid in understanding its possible applications. DATA SOURCES: This literature search was part of a larger search in which several hundred musculoskeletal diagnostic ultrasound articles were collected.

OBJECTIVES: This study evaluated the possibility of using NeuroModulation Technique (NMT), a form of intention-based medicine, to induce osteogenesis and healing of cavitational osteonecrosis, a common progressive form of ischemic disease of the alveolar arch. DESIGN: Eleven (11) adult patients were enrolled based on the presence of lesions in the jawbone. Ten (10) subjects underwent NMT therapy for up to 10 months, while 1 subject received no treatment.

The study was designed to evaluate the effects of a traditional Chinese herbal medicine Hochu-ekki-to (Bu-zong-yi-qi-tang), which was composed of 10 herbal medicines and had been used for the treatment of oligospermia and as a postoperative medication in Japan, on bone loss in rats treated with a gonadotropin-releasing hormone (GnRH) agonist. Female rats at 40 weeks of age were divided into 4 groups of 8 rats each.

We evaluated the effects of the traditional Chinese medicines, Hachimi-jio-gan, Juzen-taiho-to and Unkei-to, on bone loss in murine model of senile osteoporosis (SAMP6). Two-month-old SAMP6 were divided into control and experimental groups. The control mice had the tap water available as the only drinking fluid. The experimental mice were given 0.05% aqueous solution of Hachimi-jio-gan, Juzen-taiho-to or Unkei-to for three months. The solution intake of a mouse averaged 5 ml per day.

OBJECTIVE: To study the effect of Bushen Zhuanggu, the traditional Chinese medicine for reinforcing kidney and strengthening bone, on bone loss in female rats after simulated weightlessness. METHOD: Thirty-six female SD rats were randomly divided into 3 groups, namely normal control group (group A) and two groups of weightlessness simulated by tail suspension (groups B and C). Group C were treated with the Chinese medicine, while groups A and B were given the same dose of normal saline. The experiment lasted 28 days, and all rats were allowed to drink water freely.

Although human parathyroid hormone (1-34) [hPTH (1-34)] was reported to improve osteoporotic bone loss, little is known about the anti-osteoporotic effect of the traditional Chinese medicine, Gosha-jinki-gan (GJG). The purpose of this present study was to clarify and compare the effects of hPTH (1-34) and GJG on trabecular bone microarchitecture in ovariectomized (OVX) rat tibia by using microcomputed tomography (micro-CT). Thirty 12-week-old Sprague-Dawley female rats were underwent ovariectomy (OVX) or sham operation.

In traditional Chinese medicine (TCM), both velvet antlers (VA) and VA blood can tonify qi, essence, and marrow, nourish the blood, and invigorate bones and tendons. In TCM, the combination of VA and VA blood is believed to have superior pharmacological effects. Scientific evidence supporting the traditional therapeutic preference for redder antler is needed. The effectiveness of the combination therapy of VA middle sections (VAMs) and VA blood (VAM-B) was first examined in promoting proliferation of mouse osteoblastic cells (MC3T3-E1).
