It has previously been shown that the combination of two deleted Pelements in trans, one containing the left functional end and the second element the right functional end, can lead to high levels of male recombination. This finding strongly suggests that P-element, ends from different chromosomes can become associated, followed by “pseudo-excision.” We show that two different processes are inv...

The antioxidant activity of the aqueous crude extract of Ocimum gratissimum Linn. leaf on the basal and traumatized (cadmium-induced) serum levels of alkaline phosphatase (ALP), total acid phosphatase (ACPT) and prostatic acid phosphatase (ACPP) of the male guinea-pig (GP) were evaluated. Preliminary experimentation showed that the effects of the aqueous crude extract of O. gratissimum on basal...

Dear Editor-in-Chief, The paper by Kobayashi entitled “Temperature receptors in cutaneous nerve endings are thermostat molecules that induce thermoregulatory behaviors against thermal load” summarizes a series of elegant studies conducted by Kobayashi and colleagues during the past 30 years. These studies have challenged the “hypothalamic proportional control” model which remains the most widel...

Microsomal fraction from mouse mastocytoma was incubated for 60 min with UDP-[Wlglucuronic acid and unlabeled UDP-N-acetylglucosamine, producing nonsulfated labeled polysaccharide. Continued incubation for an additional 60-min period, in the presence of 3’-phosphoadenylylsulfate, yielded sulfated, heparin-like polymer. The incorporation of W was terminated at the beginning of the sulfation peri...

Seed lots with the genetic background of ‘Baroda’ and ‘Marketer’ cucumber (Cucumis sativus L.) containing all possible combinations (DF Df, Dfdf, dfdf) of df (which increases dormancy) and Df (wild type) were used. Dormancy was not solely due to the genotype dfdf and clear effects of genetic background were apparent. The df allele in the homozygous state induced a strong dormancy in ‘Baroda’, b...

"Nul l" mutations previously isolated at the aGpdh-1 locus of Drosophila rnelanogaster, because of disruption of the energy-producing a-glycerophosphate cycle, severely restrict the flight ability and relative viability of affected individuals. Two "null" alleles, aGpdh-18°-1-4, and otGpdh-1 ~°-~-5, when made hemizygous with a deficiency of the aGpdh-I locus, Df(2L)Gdh,4, were rendered homozygo...

Olivine-type lithium transition-metal phosphates LiMPO4 (M=Fe, Mn, Co, or Ni) have been intensively investigated as promising cathode materials for rechargeable lithium ion batteries (LIBs) owing to their high capacity, excellent cycle life, thermal stability, environmental benignity, and low cost. However, the inherently low ionic and electrical conductivities of LiMPO4 seriously limit Li + in...

The relative effect of a freeze-thaw cycle on photosynthesis, respiration, and ion leakage of potato leaf tissue was examined in two potato species, Solanum acaule Bitt. and Solanum commersonii Dun. Photosynthesis was found to be much more sensitive to freezing stress than was respiration, and demonstrated more than a 60% inhibition before any impairment of respiratory function was observed. Ph...
