When a new infectious disease emerges, memory cells from previous exposure to related, but different, micro-organism may become activated. This phenomenon has been termed the original antigenic sin. induced antibodies against related would be not functional, sin impair effectivity of primary response. Otherwise, turn out virtue because response contribute elimination emerging disease.

Adsorption of cadmium and lead ions to floc-type biosorbents was reported in this work. Two types of biosorbents containing a marine microalga, Heterosigma akashiwo (Hada) Hada, or a purple non-sulfur bacterium, Rhodobacter sphaeroides, were prepared. The micro-organisms inactivated by steam sterilization were immobilized in casein floc and cross-linked with glutaraldehyde. In the present immob...

Micro actuators for tiny robots could lead to revolutionary advances in many cutting-edge applications (e.g. minimally invasive medicine). Many prototypes were hence developed, which were powered either by micro organism, by onboard mechatronic systems or by remote magnetic fields. This paper presents two evolving designs, aiming at fabricating micro actuators which can be selectively controlle...

In the present work a new series of 3-alkyl-2,6-diarylpiperidin-4-one-2-thienoyl hydrazones have synthesized by the reaction of 3-alkyl-2, 6-diarylpiperidin-4-one with 2-thiophenecarboxylic acid hydrazide and characterized by spectral (IR, H NMR, C NMR, HSQC, HMBC, NOESY and COSY) techniques. The hydrazones were screened for their in vitro antibacterial and antifungal activities against some se...

The micro-organism Mycoplasma hominis is a common commensal of the female genital tract; the organism is found in the vagina and cervical canal of 56 per cent of women attending obstetric and gynaecological clinics (McCormack et al. 1973). It has been implicated as a pathogen in cases of puerperal sepsis (Russell and Fallon 1970; Solomon et al. 1973), particularly after traumatic vaginal delive...

1. A micro-organism similar to Arthrobacter globiformis has been isolated from sewage by elective growth on a medium containing l-threonine as sole source of carbon and nitrogen. 2. Washed cell suspensions of the organism catalyse the complete disappearance of aminoacetone from the medium and its almost complete oxidation. 3. In the presence of iodoacetate, aminoacetone disappearance is accompa...
