The iron content in seminal plasma of normal (n19), oligozoospermic (n11), azoospermic (n12), oligoasthenozoospermic (n19), and asthenozoospermic (n17) subjects was estimated by using atomic absorption spectrophotometer. The concentration of iron in normal seminal plasma varied from 265 to 365 mg%. The source of iron in seminal plasma seems to be the adnexal glands and not spermatozoa, as azoos...

It has been suggested that raising soil pH through liming could reduce the impact of whitegrub on crop yield in the treated soil. To test this hypothesis, whitegrub incidence was monitored in a trial designed to examine the effects of various lime treatments on crop yields of varieties N16 and N12. Lime was applied at two rates (5 and 10 t/ha) and in combination with gypsum at 5 t/ha each. Resu...

The effects on sucrose yield of varying the time interval between Ethrel and Fusilade Super applications in a combination treatment were tested on variety NC0376. Results suggested that Ethrel applied 12 weeks, and Fusilade Super applied eight weeks before harvesting were the most beneficial. Other varieties which responded to a combination treatment were N19, N12 and N22. Varieties N14, N19, N...

Sir, Resistance to vancomycin in Enterococcus faecium and Enterococcus faecalis is due to acquired operon structures of two types, namely the D-alanyl-D-lactate and D-alanyl-D-serine operons named for the specific ligase they harbour. The former group consists of the vanA, vanB, vanD and vanM operons and the latter group consists of the vanE, vanG, vanL and vanN operons. – 5 The D-Ala-D-Lac ope...

When NCo376 was released in 1955, it had to compete with the popular NCo310. However, its superior sucrose yield (but lower sucrose content) and wider adaptation to different growing conditions in South Africa, ensured that it became the major variety by 1965. It maintained this status until one of its seedlings, N12, produced more cane than NCo376 in 1995. From 1970/71 until the 1985/86 millin...

In 2017-2019, it was revealed that fertilizers provide 36 - 51% of the annual crops green mass yield, collection raw protein increases by 1.5 1.6 times. When N12 introduced against background phosphorus and potassium fertilizers, its content corresponded to 12.50%, when N75 introduced, increased 13.6 13.7%. Takeaway for N, P, K with use N 75 P 35 130-160 respectively times, 40 80-90% compared c...

In a previously reported model study, sugarcane was genetically engineered with the pat gene conferring resistance to the herbicide Buster®. The sugarcane cultivar used in that work was NCo310, which is no longer grown commercially but responds well to tissue culture and transformation. The field performance of the herbicide resistant sugarcane was assessed and stable transgene expression obser...

Various ethyl and benzyl spermine analogues, including the anticancer agent N1,N12-bis(ethyl)spermine, were studied for their ability to affect the growth of cultured Escherichia coli cells, to inhibit [3H]putrescine and [3H]spermine uptake into cells, and to modulate the peptidyltransferase activity (EC 2. 3. 2. 12). Relative to other cell lines, growth of E. coli was uniquely insensitive to t...
