The locations of the genetic determinants for enterocin L50 (EntL50A and EntL50B), enterocin Q (EntQ), and enterocin P (EntP) in the multiple bacteriocin producer Enterococcus faecium strain L50 were determined. These bacteriocin genes occur at different locations; entL50AB (encoding EntL50A and EntL50B) are on the 50-kb plasmid pCIZ1, entqA (encoding EntQ) is on the 7.4-kb plasmid pCIZ2, and e...

Insects have been proposed as potential alternative animal protein sources to replace fishmeal (FM), which is expensive and has limited availability for fish feed formulation. However, studies on the effects of replacing FM with black soldier fly (Hermetia illucens) larvae (BSF-L) growth performance Nile tilapia (Oreochromis niloticus) fry, water quality economic benefits are currently limited....

Low-grade oncocytic tumour (LOT) of the kidney is one emerging entities included in recently published Fifth Edition WHO classification Tumours.1 It shows overlapping morphological features with oncocytoma and chromophobe renal cell carcinoma but has unique KIT negative Keratin (KRT) 7 diffuse positive immunophenotype. Herein, we describe clinical, morphological, immunohistochemical findings tw...

Abstract This work aimed to describe the reproductive biology of Hypoptopoma inexspectatum in southern Pantanal. A total 538 individuals were sampled and analyzed from February 2009 through January 2011 We did not observe differences sex-ratio, both sexes presented positive allometric length/weight relationship (LWR). Reproduction occurs mainly February. Females reached first maturation (L50) w...

On the basis of the continuous traffic noise data observed at 142 sites distributed in 52 roads from 1989 to 2003, the characteristics of traffic noise and effect factors were analyzed through traffic noise indices, such as Lep, L10, L50, L90, TNI, and Pn. Our findings allow us to reach a number of conclusions as follows: Firstly, traffic noise pollution was serious, and its fluctuant character...

The combination of a general greening of international political debate, and the events of 1992 at the Rio Earth summit have led to great interest in the question of global environmental protection. While it is recognized that international environmental agreements (IEAs) are the means by which the earth's fragile environment is most likely to be protected, this recognition has been recent. Hen...

This study was conducted to assess the reproductive biology and early breeding behaviour of female Oreochromis niloticus reared in monoculture and polyculture with Clarias gariepinus in earthen ponds for 8 months. Results revealed no significant difference in length at first maturity (L50) between females reared in monoculture and polyculture systems. Similarly, no significant differences were ...

This study investigated the dose-dependent response in lamb meat of stable nitrogen isotope ratio to the dietary proportion of legumes, and the ability of the nitrogen isotope signature of the meat to authenticate meat produced from legume-rich diets. Four groups of nine male Romane lambs grazing a cocksfoot pasture were supplemented with different levels of fresh alfalfa forage to obtain four ...

The hole-doped standard and extended t-J models on ladders with anisotropic Heisenberg interactions are studied computationally in the interval 0.0<l<1.0 (l50, Ising; l51, Heisenberg! at small J/t . It is shown that the approximately half-doped stripes recently discussed at l51 survive in the anisotropic case (l ,1.0), particularly in the ‘‘extended’’ model. Due to the absence of spin fluctuati...
