  Title Ice planktonic algae of the strand White Sea Type Journal Article
  Year 2003 Publication Vestnik Moskovskogo universiteta Abbreviated Journal Vestn Mosk Univ (Biol)  
  Volume Issue 1 Pages 24-31  
  Keywords Phytoplankton; Cryoplankton; Biomass; Sea ice; Bays; Ecological distribution; Quantitative distribution; Pne; White Sea; Kandalakshskiy Bay  
  Abstract The species composition and abundance of algae at the upper and bottom layers of ice were investigated in the Kandalakshskiy Bay of the White Sea (Russia). The samples were collected on four stations with the different distance from the shore (depth 2-10 m). The number of littoral species decreased and the number of ice planktonic species increased with distance from the shore. The abundance of ice algae was maximal (about 1x106 cells/l) in April, with the greatest value on the station located far from the shore. The abundance of algae at the upper layer of ice was in two times lower than at the bottom ice layer. The maximum value of biomass (4 mg/l) was found at the lower layer of ice on the near shore station in April.

  Title Comparison of daily averaged reflection, transmission, and absorption for selected radiative flux-transfer approximations Type Journal Article
  Year 1994 Publication Journal of the Atmospheric Sciences Abbreviated Journal  
  Volume 51 Issue 24 Pages 3580-3592  
  Keywords Planetary-Atmospheres; Climate; Scattering; Aerosols  
  Abstract This paper compares accuracy for the daily averaged reflection, transmission, and absorption of solar flux derived from the delta-four-stream approximation and a few selected two-stream approximations. In the chosen variety of two-stream approximations, a two-stream approximation suggested by Zhu produces the most accurate reflection and transmission for conservative scattering with optical thickness tau(1) < 3. Otherwise, the delta-Eddington approximation is superior to other two-stream approximations. The delta-four-stream approximation produces errors that are smaller than the delta-Eddington approximation by at least a factor of 2.

  Title Pharmacologic rescue of axon growth defects in a human iPSC model of hereditary spastic paraplegia SPG3A Type Journal Article
  Year 2014 Publication Human Molecular Genetics Abbreviated Journal Hum Mol Genet

  Abstract Hereditary spastic paraplegias are a large, diverse group of neurological disorders (SPG1-71) with the unifying feature of prominent lower extremity spasticity, owing to a length-dependent axonopathy of corticospinal motor neurons. The most common early-onset form of pure, autosomal dominant hereditary spastic paraplegia is caused by mutation in the ATL1 gene encoding the atlastin-1 GTPase, which mediates homotypic fusion of ER tubules to form the polygonal ER network. We have identified a p.Pro342Ser mutation in a young girl with pure SPG3A. This residue is in a critical hinge region of atlastin-1 between its GTPase and assembly domains, and it is conserved in all known eukaryotic atlastin orthologs. We produced induced pluripotent stem cells from skin fibroblasts and differentiated these into forebrain neurons to generate a human neuronal model for SPG3A. Axons of these SPG3A neurons showed impaired growth, recapitulating axonal defects in atlastin-1-depleted rat cortical neurons and impaired root hair growth in loss-of-function mutants of the ATL1 ortholog rhd3 in the plant Arabidopsis. Both the microtubule cytoskeleton and tubular ER are important for mitochondrial distribution and function within cells, and SPG3A neurons showed alterations in mitochondrial motility. Even so, it is not clear whether this change is involved in disease pathogenesis. The SPG3A axon growth defects could be rescued with microtubule-binding agents, emphasizing the importance of tubular ER interactions with the microtubule cytoskeleton in hereditary spastic paraplegia pathogenesis. The prominent alterations in axon growth in SPG3A neurons may represent a particularly attractive target for suppression in screens for novel pharmacologic agents.

  Title Oral health knowledge, attitudes and behaviour of adults in China Type Journal Article
  Year 2005 Publication International Dental Journal Abbreviated Journal Int Dent J  
  Volume 55 Issue 4 Pages 231-241  
  Keywords Adult; Age Factors; Aged; *Attitude to Health; Cariostatic Agents/therapeutic use; China; DMF Index; Dental Care/economics/utilization; Dietary Sucrose/administration & dosage; Fluorides/therapeutic use; Gingival Hemorrhage/therapy; *Health Behavior; *Health Education, Dental; Health Knowledge, Attitudes, Practice; Humans; Insurance, Health, Reimbursement; *Oral Health; Risk Factors; Sex Factors; Sick Role; Toothbrushing; Toothpaste/therapeutic use; Urbanization  
  Abstract OBJECTIVES: To describe oral health behaviour, illness behaviour, oral health knowledge and attitudes among 35-44 and 65-74-year-old Chinese; to analyse the oral health behaviour profile of the two age groups in relation to province and urbanisation, and to assess the relative effect of socio-behavioural risk factors on dental caries experience. METHODS: A total number of 4,398 35-44-year-olds and 4,399 65-74-year-olds were selected by multistage stratified cluster random sampling which involved 11 provinces in China. Data were collected by self-administered structured questionnaires and clinical examinations (WHO criteria). RESULTS: 32% of the 35-44-year-olds and 23% of the 65-74-year-olds brushed at least twice a day but only 5% used fluoridated toothpaste; 30% and 17% respectively performed 'Love-Teeth-Day' recommended methods of tooth brushing. A dental visit within the previous 12 months was reported by 25% of all participants and 6% had a dental check-up during the past two years. Nearly 15% of the subjects would visit a dentist if they experienced bleeding from gums; about 60% of the subjects paid no attention to signs of caries if there was no pain. Two thirds of the urban residents and one fifth of the rural participants had economic support for their dental treatment from a third party, either totally or partially. Significant variations in oral health practices were found according to urbanisation and province. At age 35-44 years 43% of participants had daily consumption of sweets against 28% at age 65-74 years. Dental caries experience was affected by urbanisation, gender, frequency, time spent on and method of tooth brushing. Knowledge of causes and prevention of dental diseases was low with somewhat negative attitudes to prevention observed. CONCLUSION: Systematic community-based oral health promotion should be strengthened and preventive-oriented oral health care systems are needed, including promotion of further self-care practices and the use of fluoridated toothpaste.
