A cyanobacterial extracellular sheath pigment from Scytonema sp. R77DM was partially characterized and investigated for its increased production under abiotic factors, and UV-screening function. HPLC with PDA detection, and ion trap liquid chromatography/mass spectrometry analysis revealed the presence of a pigment scytonemin and its reduced counterpart. Ultraviolet radiation showed more stimul...

a Society for Community Health Awareness, Research and Action (SOCHARA), Bangalore, Karnataka, India. Correspondence to Ravi Narayan (email: [email protected]) The WHO South-East Asia Region was one of the crucibles for development of the primary health care (PHC) concept. The Bandung Conference on Rural Hygiene held in 1937 drew global attention, through the League of Nations Health Organizatio...

Let G have order 2013. For p = 3, 11, 61 denote by np the number of Sylow p-groups in G. By Sylow’s theorems we have 61 | (n61 − 1) and n61|33, which is possible only for n61 = 1. Hence the 61-Sylow subgroup B is unique and therefore normal in G. Similarly, n11 | 3× 61 and 11 | (n11 − 1) yields n11 = 1; and the unique 11-Sylow subgroup A is normal in G. Note that A ∩ B is the trivial subgroup {...

Cosmopolitan Gram-negative cyanobacteria may affect human and animal health by contaminating terrestrial, marine and freshwater environments with toxins, such as lipopolysaccharide (LPS). The cyanobacterial genus Scytonema (S) produces several toxins, but to our knowledge the bioactivity of genus Scytonema LPS has not been investigated. We recently reported that cyanobacterium Oscillatoria sp. ...

The ability to identify the functional correlates of structural and sequence variation in proteins is a critical capability. We related structures of influenza A N10 and N11 proteins that have no established function to structures of proteins with known function by identifying spatially conserved atoms. We identified atoms with common distributed spatial occupancy in PDB structures of N10 prote...

Objective: The nature of somatosensory evoked potential (SEP) studies of normal subjects is obviously much different from the patients. In this study our aim was to find out the effects of the change of stimulus frequencies on absolute latencies, amplitudes and central conduction time in median SEPs of normal subjects. Methods: Normal values of somatosensory evoked potentials were obtained from...

Solution. Let np denote the number of p-Sylow subgroups. Since n11 is 1 mod 11 and divides 12, we know n11 is either 1 or 12. If it is 1, then it is normal and we are done. So instead, assume n11 is 12. Then there must be 120 elements of order 11 in G, leaving only 12 more elements available. Since n3 is 1 mod 3 and divides 44, we know that n3 is 1, 4 or 22. If it is 1, then again it is normal ...

The cyanobacterial genus Scytonema (S) produces several toxins, but to our knowledge the 17 bioactivity of genus Scytonema LPS has not been investigated. We recently reported that 18 cyanobacterium Oscil...

Experimental data for density, viscosity, refractive index and surface tension are reported, for the first time, in the temperature range between 288.15 K and 353.15 K and at atmospheric pressure for two protic ionic liquids, namely 2-(dimethylamino)-N,N-dimethylethan-1-ammonium acetate, [N11{2(N11)}H][CH3CO2], and N-ethyl-N,N-dimethylammonium phenylacetate, [N112H][C7H7CO2]. The effect of the ...
