This research was to observe patients,who underwent orthodontic tooth alignment correction with dental brackets,for the purpose of early detection of white spots(early satge of caries)and dynamic measurement of distance between teeth edges based on the digital photographs taken with a smartphone Sony Xperia *** reading was realized taking into account the adjustment of color features of a standard ceramic surface(tile)that was selected during the dental brackets installation period,the photo of which was taken simultaneously during the dynamic observation *** color scale RGB was transformed into CIE L*a*b scale of color measurement with regard to the correction of RGB components of image by usage of correction coefficient for calibration tile surface RGB *** expert appraisal showed sensitivity of proposed method was between 88.7%and 96.2%(the mean 93.1%)and specificity between 68.4%and 84.2%(the mean 75.4%).The positive predictive value was between 89.5%and94.0%(the mean 91.5%);and the negative predictive value was between 72.7%and 86.7%(the mean 80.6%).The measurement of the distance between teeth edges during the first 10 days following the brackets installation was carried out using a self-scalable ruler that was calibrated,according to the standard sizes of the dental bracket system *** Android application of self-scalable ruler was developed using *** development of a pronounced pain syndrome was observed when the velocity of distance changes between teeth edges was rather high-0.051+0.004 mm/*** improvement of efficiency of the suggested method is expected due to application of illumination standards during the shooting period.

Enteroenteric intussusception is a condition in which full-thickness bowel wall becomes telescoped into the lumen of distal bowel. In adults, there is usually an abnormality acting as a lead point, usually a Meckels＇ diverticulum, a hamartoma or a tumour. Duodeno- duodenal intussusception is exceptionally rare because the retroperitoneal situation fixes the duodenal wall. The aim of this report is to describe the first published case of this condition. A patient with duodeno-duodenal intussusception secondary to an ampullary lesion is reported. A 66 year-old lady presented with intermittent abdominal pain, weight loss and anaemia. Ultrasound scanning showed dilated bile and pancreatic ducts. CT scanning revealed intussusception involving the full-thickness duodenal wall. The lead point was an ampullary villous adenoma. Congenital partial （type r[） malrotation was found at operation and this abnormality permitted excessive mobility of the duodenal wall such that intussusception was possible. This condition can be diagnosed using enhanced CT. Intussusception can be complicated by bowel obstruction, ischaemia or bleeding, and therefore the underlying cause should be treated as soon as possible.

Objective: To explore the protective effect of Polygonum minus ethanolic extract on cisplatininduced ***: In vitro test, total phenolic content assay and DPPH assay were performed to determine the antioxidant activity of Polygonum minus. For in vivo test, 30 male SpragueDawley rats were randomly divided into 5 groups: the control group, cisplatin 10 mg/kg, Polygonum minus 100 mg/kg, Polygonum minus 200 mg/kg and Polygonum minus 400 mg/kg. The control group and the cisplatin group were given distilled water whereas Polygonum minus groups received the respective dose of Polygonum minus extract orally for 14 d. On day 15, a single intraperitoneal administration of normal saline was given to the control group; while 10 mg/kg of cisplatin was given to the cisplatin group and Polygonum minus groups. Body weight, signs of illness, daily activity and mortality were observed at least once daily throughout the experimental period. On day 18, the anterior part of the brain was collected and processed for histological and ultrastructural analyses(right hemisphere). The remaining part(left hemisphere) of the brain was assayed to determine malondialdehyde and catalase levels for oxidative stress ***: Polygonum minus ethanolic extract possessed high phenolic content(977.6 mg GAE/g) and 95.9% DPPH radical scavenging activities. No mortality was observed in all groups. Rats in the cisplatin group were weak and less active compared to Polygonum minus treated rats. In the cisplatin group, disorganised cellular layers of the cerebral cortex were observed whereas rats treated with low and mid doses of Polygonum minus extract had normal cerebral cortex as in the control group. Mild ultrastructural changes were observed in rats treated with low and mid doses of Polygonum minus extract. Meanwhile, low and mid doses of Polygonum minus extract significantly reduced malondialdehyde level whereas low and mid doses of Polygonum minus extracts groups significantly

It is shown that an n × n matrix of continuous linear maps from a pro-C^＊-algebra A to L（H）, which verifies the condition of complete positivity, is of the form [V^＊TijФ（·）V]^n i,where Ф is a representation of A on a Hilbert space K, V is a bounded linear operator from H to K, and j=1,[Tij]^n i,j=1 is a positive element in the C^＊-algebra of all n×n matrices over the commutant of Ф（A） in L（K）. This generalizes a result of C. *** in Proc. Amer. Math. Soc., 112（3）, 1991, 709-712. Also, a covariant version of this construction is given.

BACKGROUND AND OBJECTIVE Cervical radiculopathy is a common complaint of middle to older patients at orthopedic outpatient clinics. As research has suggested that biochemical sensitizers make nerve roots susceptible to mechanical effects of a herniated mass, interleukin one and prostaglandins are commonly seen as involved in producing radiculopathy. Autologous conditioned serum (ACS) is derived by processing the patient''s blood to produce high concentrations of interleukin I receptor antagonists. This study evaluated the efficacy of ACS in patients with cervical radiculopathy who had failed conservative *** Forty patients with neck pain radiating into one upper limb for at least six weeks were randomized to receive either ACS or methylprednisolone (MPS). The subjects were assessed with a visual analogue scale (VAS) for pain, the Neck Pain Disability Scale (NPDS) and the Neck Disability Index (NDI). Measurements were made at baseline, and then at three weeks, three months and six months after *** The mean, six-month improvement in VAS scores for patients receiving ACS was 73.2%, while that for those receiving MPS was 58.4%. Over the same timeframe, the mean NPDS score decreased in the ACS group by 73.76% and in the MPS group by 55.6%. The mean NDI scores decreased by 74.47% in the ACS group and by 52.8% in the MPS *** This study of patients with cervical radiculopathy found that epidural injections of autologous condition serum are at least as effective as steroid injections for reduction of pain and disability.

The 1998 Conference of Parties to the Convention on Biological Diversity asked national governments to demonstrate the importance of biological diversity in supporting rural communities. This paper introduces‘agrodiversity’as the primary way in which farmers use biological diversity and, more generally, the natural diversity of the environment for production, including their choice of crops, and management of land, water and biota as a whole. Promoting agrodiversity and understanding how it functions in tropical smallholder farming systems is the best way that importance may be shown. A win-win scenario is presented which links agrodiversity to land degradation control and sustainable rural livelihoods as evidenced by food security. It is argued that policies that encourage biological diversity in areas of land use will not only meet countries’ responsibilities under the Convention but will also address land degradation problems and support to rural livelihoods. The human significance of various types of biological diversity is shown. Sustainable rural livelihoods are presented in the new capital assets framework to demonstrate how rural households may use various components to control land degradation. To enable agrodiversity to be implemented practically, it has been codified into core elements of: biophysical diversity, the diversity of the natural environment that controls the resource base for food production; management diversity that embraces the practices (many of them indigenous) of farmers such as live hedges, soil amendments and ridge tillage techniques; agro-biodiversity which is the diversity of crop, plant and animal combinations; and organisational diversity, the way that farms are owned and operated, and the way that capital assets are allocated. Each element is then systematically related to show how agrodiversity controls land degradation and how it promotes food security. The example of the maize-Mucuna system in South America is cited as an evide
