Study of the capsular genome of pneumococcus has shown that it controls a multiplicity of biochemical reactions essential to the synthesis of capsular polysaccharide. Mutation affecting any one of several biochemical reactions concerned with capsular synthesis may result in loss of capsulation without alteration of other biochemical functions similarly concerned. Mutations affecting the synthes...

Accommodation may be restored to presbyopic lenses by refilling the lens capsular bag with a soft polymer. After this accommodative lens refilling prevention of capsular opacification is a requirement, since capsular opacification leads to a decreased clarity of the refilled lens. It has been hypothesized that capsular fibrosis causing the capsular opacification results in increased stiffness o...

Sedimentation constants at infinite dilution have been found to be 1.89 and 4.06 for the somatic and capsular polysaccharides, respectively, from pneumococcus Type III. Intrinsic viscosities have been determined for the somatic and capsular polysaccharides of pneumococcus Type III using the Ostwald viscometer. Molecular weights and dimensions have been calculated for the somatic and capsular po...

Biological encapsulation and the foreign body reaction can impair the performance of implanted drug release devices. In this article, the classic definition of biocompatibility is questioned. Examples are presented of biomaterials showing unique healing behavior. A new paradigm for biomaterials healing is proposed in which non-specific protein adsorption is inhibited and matricellular proteins ...

The main virulence factor of Streptococcus pneumoniae is the capsule. The polysaccharides comprising this capsule are encoded by approximately 15 genes and differences in these genes result in different serotypes. The aim of this study was to investigate the sequence diversity of the capsular genes of serotypes 6A, 6B, 6C, 19A and 19F and to explore a possible effect of vaccination on variation...

Diabetic cataracts are common in diabetic dogs and lead to blindness lens-induced uveitis, the complications of which may need remove eyeball. The objectives this study were provide a clinical ophthalmological characteristics cataract dogs, describe pre-, intra- postoperative phacoemulsification identify relationships between different parameters phacoemulsification, types complications, outcom...

BACKGROUND Capsular block syndrome is an uncommon complication that occurs after cataract surgery. It is characterized by capsular distension, anterior intraocular lens displacement, anterior chamber shallowing, and unexpected myopic shifts. We report a case of recurrent fibrotic capsular block syndrome with Elschnig's pearl-type posterior capsule opacification 10 months after neodymium-yttrium...

Background: Shoulder pain encompasses a diverse array of pathologies and can affect as many one quarter the population depending on age risk factors. It may be caused by problems with neck, glenohumeral joint, acromioclavicular rotator cuff, or other soft tissues around shoulder. Aims Objectives: The main aim study is to compare diagnostic accuracy ultrasound (US) shoulder magnetic resonance im...

The major pneumococcal virulence determinant is its capsule, and pneumococcal epidemiology is based on 91 capsular serotypes, each corresponding to the structure of the capsular polysaccharide determined by the type-specific capsular genome. Here, we provide the beginnings of an approach to intertwine serotype epidemiology, capsular regulatory gene characteristics on the basis of existing seque...
