An?aminobisphosphonate-statin combination has been shown to reduce the toxicity of the mutated protein, progerin, in progeria patient cell cultures and in a mouse model of the disease. This combination is currently being tested in a European Therapeutic Trial for progeria in Marseille (ClinicalTrials.gov identifier NCT00731016). Progerin has been shown to be produced by skin cells during physiological aging. The objective of this study was to assess the efficiency of a new and original cosmetic formulation containing alendronate and pravastatin sodium salts, reduce crow’s feet wrinkles, and cheek hollow in a double blind, randomized and placebo controlled comparative study. Three cosmetic preparations were evaluated using Fast Optical in vivo Topometry of human Skin (FOITS): one containing sodium alendronate and sodium pravastatin, a placebo, and a commercial anti-aging product. Fifty-seven female and twenty-five male volunteers between 51 and 71-year-old were selected. Each subject tested two of the three products once a day, in the evening, by spreading each selected product on one side of the face. Skin micro-relief was analyzed at 0, 28, 56 and 84 days. Statistical analysis of 7 clinical qualitative (left or right side of face, gender, and 3 skin types) and 6 quantitative parameters (age, weight at each test time, wrinkle clinical grade at inclusion time) showed no statistical differences between the three tested products. In contrast, most of the 8 quantitative FOITS parameters describing skin micro-relief were statistically improved by the alendronate-pravastatin combination compared to the placebo or to the commercial anti-aging product. A cosmetic preparation containing alendronate and pravastatin sodium salts exhibited anti-aging effects by reducing crow’s feet wrinkles and restoring cheek volume.展开更多

Subjects who drank habitually and had moderately higher levels of gamma-glutamyl transferase (GGT) (50 - 100 IU/L) were enrolled. The levels of transaminases in these subjects were almost within normal levels (aspartate transaminase (AST) <30 IU/L and alanine transaminase (ALT) <40 IU/L). Either the capsules containing placebo (n = 23) or 130 mg (4.0 × 1010 colony-forming units) of live L. brevis SBC8803 (n = 22) per day were administered for the continuous eight weeks (56 days). During the period, the subjects both in test group and placebo groups have kept each drinking behavior as usual. Regarding lipid metabolism, triacylglycerol (TG) levels in the male test group significantly decreased at week 4 as compared with week 0. Biomarkers of hepatocytes-damage;AST and ALT levels showed no significant differences between the pla- cebo and test groups at both weeks 4 and 8. Oxidative stress marker;GGT at weeks 4 was significantly lower in the test group than that in the placebo group (p = 0.017), but not at weeks 8. However, taking a reduced rate of GGT at weeks 8 comparing with that at week 0, that in the test group showed larger value comparing with that in the placebo group. These data about TG and GGT suggest that, although efficacy of L. brevis SBC8803 is limited in this study, intake of the probiotic may alleviate alcoholic influence in lipid metabolism and oxidative stress.展开更多

However, if needle insertion depth is deeper than anticipated, needle penetration may cause damage to nerves, arteries and veins. Few clinical studies were done to evaluate the depth of needle length insertion reaching the intended gluteal muscle. The aim of this study was to evaluate the suitable depth of injecting RLAI. Twenty-six patients with schizophrenia were treated with RLAI, and randomly divided into two groups: 50 mm needle inserted group (Group-D, deep insertion, n = 13) and 20 mm needle insertion group (Group-S, shallow insertion, n = 13). For Group-S, the needle length was marked with a spacer at exactly 20 mm. Injections were performed by the psychiatrist or nurse, alternating between the two gluteal sites by double-cross method every two weeks. Clinical psychotic symptoms and injection site reactions were recorded throughout the study period. Experienced psychologists who were blinded from the needle-length experimental variable evaluated patients’ psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS) every two weeks. The plasma 9-hydroxyrisperidone (9-OH-RIS) concentrations were measured every two weeks;comparison data were determined on the 8th week and the 14th week. No significant difference was observed in 9-OH-RIS concentrations, psychotic symptoms, injection site skin reactions of subjects in both groups. However, in Group-D, injection site adverse reactions were confirmed in two subjects (15%). In Group-S, injection site reactions were confirmed in six subjects (46%). Although effective 9-OH-RIS concentrations were obtained with the insertion using both depth, it was concluded that the 50 mm insertion length was more suitable for dorsogluteal IM injections in adult patients with schizophrenia as demonstrated by the incidence of local adverse skin reactions.展开更多

Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine（TCM） diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient.METHODS/DESIGN： We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life.DISCUSSION： The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research.TRIAL REGISTRATION NUMBER： Clinical Trials.gov Identifier NCT02553005.展开更多

Two products were tested on 10 healthy volunteers. Each of them suffered from this particular superficial wound characterized by a peeling off a skin tab between at least two inter-toe spaces. The duration of this study belonged of 28 days with an intermediate visit to D14. Initial and outcome evaluation was performed using a 4-grade-scale depending on the severity of the inter-toe cracks. Tolerance and healing were assessed using macrophotographs. At D14 and D 28, the difference of cure between the 2 treatments was in favor of the peptide active product. The clinical score showed a best efficiency of the active compared with the excipient;indeed a significant difference between D28 and D0 was observed for the active ingredient. Active product repairs more quickly inter-toes cracks than the excipient and we noted the complete disappearance of the “severe” and “moderate” stages from the 14th day. This study showed clearly a fast (in 14 days) and beneficial effect of the application of LN-5 compared with the excipient, on the cutaneous repair of inter-toes cracks. Since LN-5 fragment is capable of producing immediate biological activity and reinforcing the dermal-epidermal junction, it can accelerate tissue repair.展开更多
