A major mechanism for bacterial resistance to antibiotics is through the acquisition of a plasmid coding for resistance-mediating proteins. Described herein is a strategy to eliminate these plasmids from bacteria, thus resensitizing the bacteria to antibiotics. This approach involves mimicking a natural mechanism for plasmid elimination, known as plasmid incompatibility. The compound apramycin ...

The genetic basis of vegetative incompatibility in the cellular slime mold, Dictyostelium discoideum, is elucidated. Vegetatively compatible haploid strains from parasexual diploids at a frequency of between 10(-6) and 10(-5), whereas "escaped" diploids are formed between vegetatively incompatible strains at a frequency of approximately 10(-8). There is probably only a single vegetative incompa...

Uncovering the genetic and molecular basis of barriers to gene flow between populations is key to understanding how new species are born. Intrinsic postzygotic reproductive barriers such as hybrid sterility and hybrid inviability are caused by deleterious genetic interactions known as hybrid incompatibilities. The difficulty in identifying these hybrid incompatibility genes remains a rate-limit...

Many different blood group systems, such as Rh, ABO, Kell, Kidd, Duffy, MNS, have been reported as causes of hemolytic disease of the newborn. Hemolysis due to minor blood group incompatibility in the fetus or newborn has been determined in isolated case reports. Here, we report a case of a patient who had received red cell transfusion due to severe Rh c and E incompatibility, leading to hemoly...

although abo incompatibility between mother and fetus has long been suspected as cause of spontaneous abortion in man, its precise contribution has not been completely resolved. in spite of reports in which the incompatible mating was recognized to be a cause of habitual abortion, and which eventually results in infertility or a reduction in the number of living children compared with the numbe...

Maternally inherited variants, which arose within a laboratory colony of Culex pipiens fatigans, have been studied by rearing cultures from single egg rafts. Segregation, i.e, variation of cytoplasmic incompatibility properties between the male progeny of individual females, was demonstrated. Also, from the daughters of individual females, sub-lines were derived within which all the males showe...

Self-incompatibility is considered to be a growth limiting factor in fruit plants. In species with hermaphrodite flowers, S-locus (S-allele) has been accepted control self-incompatibility, and the genetic of this locus provided by multiple genes (alleles). Pear (Pyrus communis L.) belongs Pomoideae from Rosaceae family found have great potential terms ecological features Turkey. To protect thes...

biochar and activated carbon, as carbon-rich porous materials, have wide environmental applications. in the present research, rice husk (rh) was used for preparation of biochar at 400, 600, and 800 °c under simple pyrolysis, physically-activated carbon with water steam, chemically-activated carbon with potassium hydroxide (koh), and physiochemically-activated carbon with koh and steam. physical...
