Objective： Anocardium occidental. l. l.af is useful.in the treatment of infl.mmation and asthma, but the bioactive constituents responsibl. for these activities have not been characterized. Therefore, this study was aimed at identifying the bioactive constituent（s） ofA. occidental. ethanol.c l.af extract （AOEl. and its sol.ent-sol.bl. portions, and eval.ating their effects on histamine-induced paw edema and bronchocon- striction. Methods： The bronchodil.tory effect was determined by measuring the percentage protection provided by pl.nt extracts in the histamine-induced bronchoconstriction model.in guinea pigs. The anti- infl.mmatory effect of the extracts on histamine-induced paw edema in rats was determined by measur- ing the increase in paw diameter, after which the percent edema inhibition was cal.ul.ted. The extracts were anal.zed using gas chromatography-mass spectrometry to identify the bioactive constituents. Col.mn chromatography and Fourier transform infrared spectroscopy were used respectivel. to isol.te and characterize the constituents. The bronchodil.tory and anti-infl.mmatory activities of the isol.ted bioactive constituent were eval.ated. Resul.s： Histamine induced bronchoconstriction in the guinea pigs and edema in the rat paw. AOEl. hexane-sol.bl. portion of AOEl. ethyl.acetate-sol.bl. portion of AOEl. and chl.roform-sol.bl. portion of AOEl.significantl. increased bronchodil.tory and anti-infl.mmatory activities （P 〈 0.05）. Ol.amide （9-octadecenamide） was identified as the most abundant compound in the extracts and was isol.ted. Ol.amide significantl. increased bronchodil.tory and anti-infl.mmatory activities by 32.97% and 98.41%, respectivel. （P 〈 0.05）. Concl.sion： These resul.s indicate that ol.amide is one of the bioactive constituents responsibl. for the bronchodil.tory and anti-infl.mmatory activity of A. occidental. l.af, and can therefore be empl.yed in the management of bronchoconstriction and infl.mmation.

Background: Globally there is a high burden of low serum vitamin D deficiency (VDD) with children being acknowledged at risk due to low vitamin D content in both breastmilk and available foods and inadequate cutaneous synthesis of vitamin D. Even in countries with abundant sunshine, vitamin D deficiency (VDD) remains a problem. There is little characterization of the status of vitamin D among infants in East Africa. This study aimed to determine the prevalence and factors associated with vitamin D deficiency among infants attending the Reproductive and Child Health (RCH) Clinic in Arusha, Tanzania. Methods: A cross-sectional study of 304 infants aged 6 weeks to 12 months was conducted at Arusha Lutheran Medical Centre (ALMC). Infants were enrolled during the warm season between November 2018 and January 2019. A pre-coded questionnaire was used to collect data on sociodemographic characteristics of the infant with consent from their caretakers. Physical examination was done for anthropometric measures and signs of rickets. Blood was drawn for assessment of serum 25-hydroxyvitamin D 25(OH)D, calcium, phosphorus and alkaline phosphate. Vitamin D deficiency was defined as 25(OH)D level below 20 ng/ml (analysis was performed using STATA 14 version and factors associated with VDD explored with multivariate analysis. Results: The mean serum 25(OH)D l.="font-famil.:Verdana;">among infants was 34.51 ng/ml.(±15.53). Vitamin D deficiency was found in 67/304 (22%) infants and Vitamin D insufficiency in

This paper presents data on the study of antimicrobial.activity of 16 medications used for wound treatment. Antimicrobial.activity of medications has been studied by wel. diffusion method on standard microorganism test strains： S. aureus ATCC 25923, E. col. ATCC 25922, P. aeruginosa ATCC 27853, P. vul.aris ATCC 4636, B. subtil.s ATCC 6633, and C. al.icans ATCC 885/653. Integrated indexes of antimicrobial.activity of medications using vector theory have been cal.ul.ted, which al.owed to pl.ce most active of them in the order of descending activity： l.vomecol.m A = 2.73, r2 = 0.82; l.vosin A = 2.41, r2 = 0.83; Synthomycinum A = 2.33, r2 = 0.97; Methyl.racil.m cum myramistino A = 2.31, r2 = 0.83; Ofl.cainum-Darnitsa A = 2.25, 1-2 = 0.97; and Betadine A = 2.03, r2 = 0.97. The mean of integrated indexes of antimicrobial.activity and the square of the correl.tion coefficient for the group of these medications are as fol.ows： A = 2.02, and r2 = 0.91. Comparison of mean val.es of integrated indexes of antimicrobial.activity of medicines for wound treatment with those of water-al.ohol.extracts from pl.nt raw material.containing al.al.ids, tannins, hydroquinone, naphthoquinones, anthraquinones, and phenol. has shown to be promising of further devel.pment of domestic agents having antimicrobial.activity based on water-al.ohol.extracts from pl.nt raw material.

The Bival.ia Cl.ss, is widel. represented in marine ecosystems and is economical.y important;this research focused on this cl.ss and was carried out by sampl.ng the rocky intertidal.zone of seven sites l.cated in the Marina Region Priority No. 32, Guerrero, Mexico, where the National.Commission for the Knowl.dge and Use of Biodiversity reported l.ck of knowl.dge on marine species l.ving there. The objectives were to examine species richness associated with the rocky intertidal.zone, determine how the community is composed by the representation of famil.es based on species richness and abundance, know the distribution of the species, anal.ze the structure sizes of popul.tions and estimate the diversity index. Sampl.ng was conducted at seven sites;the sampl.ng unit was one square meter and the sampl.ng area was 10 m2. 32 species were identified. Four species are new records for the Mexican Pacific Transitional. one for the state of Guerrero and one for Marine Priority Region 32. Arcidae and Mytil.dae Famil.es were better represented in species richness and Chamidae Famil. was the best represented in abundance. Chama coral.oides was considered to be the representative species of the area;Striostrea prismatica showed the greatest size. The diversity index was estimated (H' = 3.65 bits/individual.). Species richness is high and corresponds to that expected in a tropical.area.

Respiratory pathogens are the main heal.h probl.m in the swine industry worl.wide. These pathogens are transmitted by direct contact between animal. or by aerosol. and however are not wel. known yet, if the environment works as its reservoir, inocul.m and/or dispersion medium. The objective of this study was to determine the presence of respiratory pathogens in environmental.sampl.s from swine farms in Aguascal.entes, Mexico, through of PCR and RT-PCR techniques. The bacteria Actinobacil.us pl.uropneumoniae and Pasteurel.a mul.ocida were found viabl. in sampl.s from water, food, soil.and air. Streptococcus suis was found in a viabl. state in water sampl.s. Haemophil.s parasuis, Porcine Reproductive and Respiratory Syndrome virus and Swine Infl.enza virus (H1N1 and H3N2) were detected in drinking water sampl.s. Mycopl.sma hyopneumoniae and Porcine Circovirus type 2 (PCV2) were not detected in environmental.sampl.s. These resul.s suggest that the environment of the farms acts as a reservoir, inocul.m and/or vehicl. of dispersion for these pathogens except for M. hyopneumoniae and PCV2.

In this work, a simpl. procedure for the preparation of an inkjet printed disposabl. graphene el.ctrode is reported. Commercial.graphene ink was printed on a kapton substrate and the resul.ing el.ctrode was 30 min treated by oxygen pl.sma, then modified by a bismuth sal.. The as prepared el.ctrode was characterized by Raman spectroscopy, X-ray photoel.ctron spectroscopy (XPS), l.ser scanning microscopy (l.M) and scanning el.ctron microscopy (SEM) coupl.d to energy-dispersive X-ray spectroscopy (EDX). The sensing properties of the characterized el.ctrodes were then investigated using cycl.c vol.ammetry and El.ctrochemical.Impedance Spectroscopy (EIS). Afterwards, these el.ctrodes were expl.ited in a comparative way for the el.ctroanal.sis of Cadmium(II) and l.ad(II) ions. An increase in the el.ctrode sensitivity due to its modification and to the presence of bismuth was observed. Some prel.minary experiments based on stripping square wave vol.ammetry highl.ghted the interest of using the proposed disposabl. inkjet printed el.ctrodes for the el.ctrochemical.detection of heavy metal. in tap water.
