Arsenic Induced Changes in Growth and Physiology of Maize (Zea mays L.) Seedlings and its Possible Amelioration Using Phosphate

Posted on

The response of maize (Zea mays L.) to different levels of arsenate with or without phosphate was investigated. Arsenic exposure significantly hampered the growth of maize seedlings showing reductions in root and shoot lengths together with reductions in fresh and dry weight. The level of total chlorophyll, chlorophyll a, chlorophyll b and carotenoids decreased in arsenic treated seedlings. Arsenic toxicity was associated with an increase in the activities of the anti-oxidative scavenging enzymes catalase and peroxidase. Arsenic restricted the concentration of nucleic acids (DNA and RNA) and soluble protein content in maize seedlings.

35-Year Studies of Reproduction in Marine Invertebrates and the Influence of Climatic Factors on it

Posted on Updated on

The studies of fouling of pioneer artificial substrates, conducted for the past 35 years near the coast of Primorsky Territory, Sea of Japan, Russia, have revealed an asynchronism in reproduction of invertebrates. Juveniles of Japanese scallop Patinopecten yessoensis and other widely distributed bivalves of boreal origin (Mytilus trossulus and Hiatella arctica) were, as a rule, abundant (over 250 scallops per a square meter of artificial substrate) in the odd-numbered years from 1977 to 1985. This is related mainly to the duration of ice season in previous winter, amount of precipitation, surface water salinity, and wind speed in June.

Prediction Models of Copepods Biomass from the Mass-Length and Carbon Content-Length Relationship

Posted on Updated on

Adult calanoid copepods of six species were collected in the Ensenada de La Paz in autumn 2010. Prosome length, dry mass and carbon content were measured to determine the mass-length relationship and the condition factor. Acartia clause, A. lilljeborgii, Temora discaudata and Undinula vulgaris were the species with high determination coefficients (p <0.05) compared to Centropages furcatus and L. johnsoni (p> .05). The condition factor of the species is the first reference for subtropical copepods in the study area. Depending on the species, organic carbon fluctuated between 20 and 47% of the dry mass and only for A. clause was the premise of 45% carbon dry mass satisfied.

Poisoning of Cattle Feeding on Allium ampeloprasum

Posted on

Ten days after ingesting a large quantity of Allium ampeloprasum (kurrat), 10 one-year-old calves and 2 eight-year-old cows in a group of cattle were referred for voiding dark-red urine, generalized jaundice, anemic or icteric mucous membranes, lack of appetite, and lethargy. Hematologically, Heinz bodies – hemolytic anemia, polychromasia, anisocytosis and leukocytosis were detected.

Pre-Symptomatic Diagnosis of Ebola Virus Infection

Posted on

The epidemic of Ebola virus disease (EVD) that occurred in West Africa during 2013-2014 was a reminder that such outbreaks may continue indefinitely. With the aim of improving diagnosis of EVD early after possible exposure, we worked with data from studies published before the outbreak to ask if changes in the infected host might be assayable within a day of infection, well before the accumulation of viral proteins or nucleic acid which may take several days and on which all existing assays are based. We studied the changes in macaque and human peripheral blood cell gene expression after infection with Zaire Ebolavirus (ZEBOV) to identify host responses that occur before the appearance of indications. We recognised host mRNAs that were differentially communicated at early, middle, and late times after infection.

Hepatitis B Virus Genotype G

Posted on

Hepatitis B virus can be divided into 10 genotypes based on sequence heterogeneity. HBV genotype G (HBV-G) has little genetic variation and often co-exists with another HBV genotype. HBV-G infections have been detected around the world, but rarely from Africa. Over a 9 year period, 3 patients were identified with HBV-G infection while attending a specialist Liver Clinic at a tertiary hospital in Cape Town, South Africa. The aim of this study was to describe the clinical and laboratory features of the patients and sequence the full HBV-G genome to determine the phylogenetic relationship with other HBV-G isolates from around the world. Further, co-infection with other HBV genotypes was determined using a multiplex type- specific PCR and cloning. All patients (2 of Caucasian and 1 of Asian ethnicity) belonged to a high risk group of men who have sex with men and were HBeAg positive. Two patients were co-infected with HIV and HBV co-infection (HBV-A) could only be identified in one case.
